    Pedestrians are considered as one of the most vulnerable road users in less developed countries (LDCs). Yet, pedestrian safety remains poorly addressed in both urban and rural transportation plans in most LDCs. Since most pedestrian injury severity studies are conducted in developed countries, this study fills the gap with an inquiry focused on a highly urbanized region of an LDC that faces a rapid increase in car ownership and increasing pedestrian-related traffic injuries, documenting specific pedestrian safety issues and providing guidance for injury prevention measures in such places. Using the Metro Manila Accident Reporting and Analysis System (MMARAS) data from 2008 to 2011, this study combines binomial logistic regression and street level analysis that further explores the statistical results and examines other factors that contribute to collisions and increase the potential for serious injury or death in three cities in Metro Manila: Makati, Manila, and Quezon. The results of the binomial regression analysis show that traffic crashes that involve heavy and multiple vehicles, and an elderly pedestrian (60 years old and above), as well as those that occurred during the evening (7 pm to midnight) and late at night (1 am to 5 am) have significantly higher odds of resulting in a fatal outcome; when the crash involves a female pedestrian and when the road surface is wet the odds of a fatal outcome are lower. Moreover, by closely examining the environment of these roadways, the study finds that most pedestrian fatalities occur on high-speed, high-traffic-volume, multilane roadways, that are surrounded by land uses that generate a particularly problematic mix of heavy vehicular and pedestrian traffic. The street level analysis also finds that fatal pedestrian crashes occur close to different types of transit stations. The results of this study of three cities in Metro Manila, reflect the twofold challenge to pedestrian safety in rapidly urbanizing areas in

    A total of 265 chicken parts were collected from 15 wet markets and 15 supermarkets in Metro Manila, Philippines. Campylobacter spp. was isolated on modified charcoal cefoperazone deoxycholate agar plates and identified through biochemical tests and PCR amplification of genus and species specific genes. Antimicrobial resistance profiles were determined following Clinical and Laboratory Standards Institute protocols. Two hundred seven (78%) Campylobacter spp. were isolated. C. jejuni and C. coli were detected from 170 (64%) and 32 (12%) of the samples, respectively. Liver and skin samples had the greatest level of contamination. Most of the isolates were resistant to clindamycin (98.6%), erythromycin (98.6%), nalidixic acid (98.1%), tetracycline (94.2%), gentamicin (65.2%), and chloramphenicol (52.6%). The results indicated that poultry meat sold in markets in Metro Manila is contaminated with drug resistant Campylobacter.

    The Philippines, located in the Northwestern Pacific Typhoon gateway to Asia, is considered one of the most susceptible to tropical cyclone related hazards. One of the most disastrous effects of tropical cyclones is storm surge. With Metro Manila being a coastal area and the most populous region in the country, with approximately 12.8 million people residing in it, it is of great interest to determine the possibility of generating significant level of storm surge in the country's capital. The necessity to determine the storm surge susceptibility was brought upon by the effect of Typhoon Haiyan on eastern Visayas in 2013, where more than 6,000 people died and resulted to about 2.86 billion dollars' worth of damages. To achieve the objectives, the actual tracks and wind speed of historical typhoon (JMA data since 1951) was mapped for the Philippines. The simulated wind speed map shows that the maximum winds are mostly experienced on the eastern side of the country; with a considerable decrease in wind intensity as the typhoon reaches the western seaboard due to land surface. The Haiyan-strength wind speed is then applied to the actual historical typhoon tracks to determine the hypothetical values of wind speed as a typhoon with Haiyan intensity reached Metro Manila. Results show that, if a typhoon with a Haiyan-like intensity is to traverse tracks like those of Rita 1978, Collen 1992, Sybil 1995, Bebinca 2000 and Xangsane 2000, there is a huge possibility of generating storm surge height of 3.9 to 5.6 m in the western seaboard of Metro Manila, even after considering the diminishing effect of surface friction.

    The study looks into the occupational safety and working conditions among bus drivers in Metro Manila, the Philippines. Quantitative data were collected through survey interviews of 95 bus drivers using the stratified sampling technique. Results showed that bus drivers worked an average of 16 h/day and were engaged in risky driving behaviors such as over-speeding and road racing in order to reach their quota for the day. Fifty-nine percent experienced work-related accidents, with a mean of three accidents. The most common accident was hitting another vehicle followed by side swipe. The accidents were blamed on other drivers, followed by vehicle defect, inattentiveness and tiredness/micro-sleep or sudden involuntary sleep while driving. The most common health symptoms experienced by the bus drivers were fatigue, back pain, and cough and colds. This study underlines the need for an occupational health and safety program for bus drivers in the Philippines.

    In many low- and middle-income countries informal communities-also termed slum and squatter areas-have become a dominant and distinct form of urban settlement, with ever increasing populations. Such communities are often located in areas of high hazard exposure and frequently affected by disasters. While often recognised as one of the highest 'at risk' populations, this paper will argue that informal settlers have been directly and indirectly excluded from many formal mechanisms, thereby increasing their vulnerability to disaster events. Household surveys were conducted across several frequently flooded informal coastal communities in Metro Manila, the Philippines, following a major typhoon and storm surge disaster. The study revealed a large level of diversity in socio-economic vulnerability, although all households faced similar levels of physical exposure and physical vulnerability. Disaster risk reduction policies and responses need to better integrate informal settlement areas and recognise the diversity within these communities. © 2016 The Author(s).

    This study examined differences in food preferences and dietary intake among male and female Filipino adolescents of different nutritional status as measured by body mass index (BMI). One hundred and twenty 13-17-year olds from various schools and communities in Metro Manila, The Philippines were selected through quota sampling with BMI, sex and age as criteria. Data on mean dietary intake and food preference were collected using pretested instruments--a 3-day food record and a food preference questionnaire, respectively. Resulting values were analysed using one-way ANOVA, Bonferroni test and Pearson's product-moment and Spearman's correlation using SAS Enterprise Guide version 2. Preference for cereals prepared with added sugar or fat (p=0.21, p=.0240), and low fat meat (p=0.18, p=0.420) were found to be positively correlated with BMI, while preference for fruits that are high in vitamin A (p=-0.18, p=0.430) was negatively correlated with the said variable. Overweight respondents gave lower and significantly different preference scores to donut (p=.02780), banana cue (p=.0489) and mayonnaise (p=.0291). Respondents of different nutritional status also had statistically different intakes of fibre, calcium and phosphorus, corresponding with the positive correlation of fibre (p=0.25231, p=0.0054), calcium (p=0.2529, p=0.0134) and phosphorus (p=0.25887, p=0.0043) intake with BMI. With respect to sex, male respondents gave statistically higher preference for French fries (p=.0370), tofu (p=.0005), garlic (p=.0190) and mussels (p=.0023). Also, males have significantly higher intakes of energy and carbohydrate than female respondents. Results suggest that food preferences should be considered in the nutritional care management of malnourished adolescents.

    A storm surge is the sudden rise of sea water over the astronomical tides, generated by an approaching storm. This event poses a major threat to the Philippine coastal areas, as manifested by Typhoon Haiyan on 8 November 2013. This hydro-meteorological hazard is one of the main reasons for the high number of casualties due to the typhoon, with 6300 deaths. It became evident that the need to develop a storm surge inundation map is of utmost importance. To develop these maps, the Nationwide Operational Assessment of Hazards under the Department of Science and Technology (DOST-Project NOAH) simulated historical tropical cyclones that entered the Philippine Area of Responsibility. The Japan Meteorological Agency storm surge model was used to simulate storm surge heights. The frequency distribution of the maximum storm surge heights was calculated using simulation results of tropical cyclones under a specific public storm warning signal (PSWS) that passed through a particular coastal area. This determines the storm surge height corresponding to a given probability of occurrence. The storm surge heights from the model were added to the maximum astronomical tide data from WXTide software. The team then created maps of inundation for a specific PSWS using the probability of exceedance derived from the frequency distribution. Buildings and other structures were assigned a probability of exceedance depending on their occupancy category, i.e., 1% probability of exceedance for critical facilities, 10% probability of exceedance for special occupancy structures, and 25% for standard occupancy and miscellaneous structures. The maps produced show the storm-surge-vulnerable areas in Metro Manila, illustrated by the flood depth of up to 4 m and extent of up to 6.5 km from the coastline. This information can help local government units in developing early warning systems, disaster preparedness and mitigation plans, vulnerability assessments, risk-sensitive land use plans, shoreline

  10. The demographic impact of the Philippine family planning program: a tale of two Metro Manilas.

    PubMed

    1993-11-01

    This pamphlet predicts the rates of contraceptive prevalence, total fertility, and population growth in the Philippines during 1970-2000. Contraceptive prevalence was 14.5% in 1970 and is expected to be 50% in 2000. Total fertility was 5.9 in 1970 and is expected to be 3.2 in 2000. Population was 36 million in 1970, 65 million in 1993, and is expected to be 75 million in 2000. If the family planning program had not continued to expand after 1970, population would have been 75 million in 1993 and would rise to 96.7 million in 2000. With expanded family planning, the difference in population for 2000 is 22 million people, or the equivalent of 2 metropolitan Manilas. A projected population that is smaller by 22 million is important for carrying capacity. A summary is given of the world situation proposed by Worldwatch. The projection is for increased demand for food from the 90 million people a year added to total world population. Food output during 1950-84 increased dramatically. However recent trends indicate that fish harvests from oceans have leveled off at 100 million tons a year and fish prices have risen rapidly. Fresh water shortages are now apparent in the United States, Mexico, China, India, and the Middle East. Grain production has slowed. Per capita output of rice, corn, and wheat has declined by 11% since 1984. World stocks of rice are low. Grain prices have doubled on the Chicago Board of Trade. Fertilizer use has declined 12% since 1989. Much crop production has reached maximum yields. Topsoil is disappearing, and cropland expanded only 2% in the last 10 years. Since 1945, 2 million hectares of land have been degraded by overgrazing, deforestation, and agricultural mismanagement.

    With a minimum of 6000 tonnes/day municipal waste output, and with NO existing operational sanitary landfill and with incineration illegal, Metro Manila has a very serious solid waste disposal problem. Unsorted municipal waste are being piled in open dumps, the most notorious of which is the Payatas open dump. A recent, tragic garbage-slide in this open dump caused dozens of deaths, news of which were broadcast internationally. Political expediency laced with a lot of corruption, rather than sound science, was the main basis for selecting this site as an open dump. As an example, this dump is situated < 1 km from the Novaliches Watershed Reservation, one of the main sources of drinking water for Metro Manila’s 12 million population! Yet, after dumping operations that have lasted more than 10 years, only recently were the preliminary geologic studies begun. Payatas is not a designed landfill and its untreated leachate is openly polluting the headwaters of the Marikina and Pasig Rivers. In addition, during the summer months, there is always the constant threat of fire due to methane induced burning from the dump, aside from the aerial pollution from dioxins and furans derived from incomplete combustion of municipal solid waste. With limited funding from the Quezon City government, a feasibility study was conducted to assess the methane generation potential of Payatas. This interdisciplinary study comprised bedrock geological studies, topographic mapping of the dump, drilling of the dump to obtain stratigraphic solid waste samples for waste characterization, laying of horizontal methane and dewatering pipes, and preliminary methane flow studies. The waste characterization has highlighted the unusually high organic (especially yard waste) component of the solid waste dumped at Payatas. Waste characterization shows that a significant portion of the waste is plastics. Several cross-sections cut across the dump show that the side slopes of the dump are on the average

    Summarizing the general characteristics of food consumption pattern and dietary status of the country's central urban region, the following are brought to focus: Metro Manila as compared to all urban and rural areas consumes less cereal grains but more sugars and fats and oils; consumes more of the high quality protein foods such as meat, poultry, eggs, milk and dried beans; and consumes less of fruits and vegetables. Availability and affordability of foods in the respective sectors could have affected to a large extent the magnitude of consumption differences. Although urban households had the advantage of a more varied and quantitatively higher food consumption, their nutrient intake was not really very different from rural households. Metro Manila still had a 13.7 percent calorie gap in its intake in 1987, and intake of ascorbic acid was notably lower than the rural sector. However, intake of thiamin and riboflavin as well as fat was appreciably higher in the metropolis. Briefly identifying the trends in food consumption with reference to six survey year periods from 1974 to 1987 (excluding 1984 and 1985), Metro Manila diet disclosed the following: increasing trend for sugars and syrups as well as dried beans, nuts and seeds and decreasing trend for cereal products, fruits and vegetables and condiments and others. There was a decrease in overall food consumption among Metro Manila households during the economic crisis that transpired in 1984 and 1985. However, there was a steady consumption of rice which was under price control, and a significant increase in the intake of some food items particularly green leafy and yellow vegetables which were among the cheapest food items available in Metro Manila markets. Some food adjustments were evidently resorted to during the period of economic dislocation showing the resiliency of the urban population. Metro Manila has been apparently drawing inordinately large amounts of the food supply from the rest of the country

    In recent decades, the practice of environmental impact assessment (EIA) in the planning processes of infrastructure projects has created significant awareness on the benefits of environmentally sound and sustainable urban development around the world. In the highly urbanized megacities in the Philippines, like Metro Manila, high priority is given by the national government to structural flood mitigation measures (SFMM) due to the persistently high frequency of flood-related disasters, which are exacerbated by the on-going effects of climate change. EIA thus, should be carefully and effectively executed to maximize the potential benefits of the SFMM. The common practice of EIA in the Philippines is generally qualitative and lacks clear methodology in evaluating multi-criteria systems. Thus, this study proposes the use of the rapid impact assessment matrix (RIAM) technique to provide a method that would systematically and quantitatively evaluate the socio-economic and environmental impacts of planned SFMM in Metro Manila. The RIAM technique was slightly modified to fit the requirements of this study. The scale of impact was determined for each perceived impact, and based on the results, the planned SFMM for Metro Manila will likely bring significant benefits; however, significant negative impacts may also likely occur. The proposed modifications were found to be highly compatible with RIAM, and the results of the RIAM analysis provided a clear view of the impacts associated with the implementation of SFMM projects. This may prove to be valuable in the practice of EIA in the Philippines. Copyright © 2013 Elsevier B.V. All rights reserved.

    STUDY BACKGROUND AND OBJECTIVES: The Philippines is one of the 22 countries with high TB burden. DOTS was adopted not only by purely public providers (PP) but also by public-private mix (PPM) facilities. This study aims to identify the patient and facility factors that promote completion of TB treatment in DOTS facilities in an urban setting. The study also explores the difference between the PP and PPM DOTS facilities in terms of case management and treatment outcomes. [Methods] A case control study was done by interviewing 394 patients sampled from TB cohort report between 2003 and 2005 of 14 DOTS facilities in Metro Manila. Statistical analyses used include chi-square test and logistic regression analysis. Being female and aged 30-44 (OR = 7.04; 95% CI 1.12-44.35), unemployed (OR = 2.73; 95% CI 1.18-6.33), being above per capita poverty threshold (OR = 2.03; 95% CI 1.03-3.99), having experienced at least one of the signs and symptoms of TB (OR = 4.64; 95% CI 1.29-16.67), taking the medication at health facility (OR = 3.87; 95% CI 1.48-10.16) and patient's understanding of DOT (OR = 2.67; 95% CI 1.37-5.23) predict TB treatment completion. Public-private mix type of DOTS facility was also significantly associated with completing treatment (chi 2 (1) = 54.76, p = 0.000). Patient factors like middle-aged female compared to female aged more than 60, being above per capita poverty threshold, unemployment and having experienced at least one signs and symptoms of TB and facility factors like providing treatment at the facility and explaining the DOT to patient increase the likelihood of completing treatment. Thus, encouraging patients to take their medication at the facility and helping the patients understand the importance of DOT can increase TB treatment completion. The seemingly better DOTS implementation and treatment outcomes by the PPM must be evaluated further through cost effectiveness and efficiency studies.

    A hybrid piecewise rainfall value interpolation algorithm was formulated using the commonly known Inverse Distance Weighting (IDW) and Gauss-Seidel variant Successive Over Relaxation (SOR) to interpolate rainfall values over Metro Manila, Philippines. Due to the fact that the SOR requires boundary values for its algorithm to work, the IDW method has been used to estimate rainfall values at the boundary. Iterations using SOR were then done on the defined boundaries to obtain the desired results corresponding to the lowest RMSE value. The hybrid method was applied to rainfall datasets obtained from a dense network of 30 stations in Metro Manila which has been collecting meteorological data every 5 minutes since 2012. Implementing the Davis Vantage Pro 2 Plus weather monitoring system, each station sends data to a central server which could be accessed through the website metroweather.com.ph. The stations are spread over approximately 625 sq km of area such that each station is approximately within 25 sq km from each other. The locations of the stations determined by the Metro Manila Development Authority (MMDA) are in critical sections of Metro Manila such as watersheds and flood-prone areas. Three cases have been investigated in this study, one for each type of rainfall present in Metro Manila: monsoon-induced (8/20/13), typhoon (6/29/13), and thunderstorm (7/3/15 & 7/4/15). The area where the rainfall stations are located is divided such that large measured rainfall values are used as part of the boundaries for the SOR. Measured station values found inside the area where SOR is implemented are compared with results from interpolated values. Root mean square error (RMSE) and correlation trends between measured and interpolated results are quantified. Results from typhoon, thunderstorm and monsoon cases show RMSE values ranged from 0.25 to 2.46 mm for typhoons, 1.55 to 10.69 mm for monsoon-induced rain and 0.01 to 6.27 mm for thunderstorms.

Yoshihiro Kinugasa (Association for the Development of Earthquake Prediction) Katsumi Kurita (Tokyo Metropolitan College of Industrial Technology) Makoto Omura (Kochi Womes's University) Tomoya Oku (Earth Remote Sensing Data Analysis Center) Many ground deformations have been occurred by earthquakes and volcanic activities in the Republic of the Philippines. The monitoring of deformation using InSAR, which is capable to observe a wide area at high spatial resolution, as well as GPS measurement and leveling survey, which are capable to measure the point-based but subtle land displacement less than a centimeter, is actively conducted in this country. The Valley fault exhibits fault creep displacement. It is a north-south trending active fault on the eastern edge of the Metro Manila district, central Luzon. Some buildings and road pavement are damaged by vertical displacement of the ground where the central segment of the fault passes through. Moreover, overpumping of groundwater in the Metro Manila district has occurred huge ground subsidences. The purpose of this study is to investigate the distribution of spatial and temporal change on the earth surface around Metro Manila. We measured long-term ground deformation from 2003 until 2010 by means of InSAR and time series analysis using ENVISAT/ASAR data. As a result, it shows that the uplift phenomena in the western part of Valley fault are uniform. On the other hand, the land movement in the eastern part of the Valley fault had reversed from subsidence to uplift in around 2007. It would be difficult to conceive that these tendencies resulted from groundwater pumping. We applied DInSAR using TerraSAR-X data in order to measure the detailed spatial distribution of creep displacement around the Valley fault. Additionally, we tried to detect a steep gradient of interferometric phase using the first differentiation. From this analysis, some segments in the direction

    In recent years, the practice of environmental impact assessment (EIA) has created significant awareness on the role of environmentally sound projects in sustainable development. In view of the recent studies on the effects of climate change, the Philippine government has given high priority to the construction of flood control structures to alleviate the destructive effects of unmitigated floods, especially in highly urbanized areas like Metro Manila. EIA thus, should be carefully and effectively carried out to maximize or optimize the potential benefits that can be derived from structural flood mitigation measures (SFMMs). A utility-based environmental assessment approach may significantly aid flood managers and decision-makers in planning for effective and environmentally sound SFMM projects. This study proposes a utility-based assessment approach using the rapid impact assessment matrix (RIAM) technique, coupled with the evidential reasoning approach, to rationally and systematically evaluate the ecological and socio-economic impacts of 4 planned SFMM projects (i.e. 2 river channel improvements and 2 new open channels) in Metro Manila. Results show that the overall environmental effects of each of the planned SFMM projects are positive, which indicate that the utility of the positive impacts would generally outweigh the negative impacts. The results also imply that the planned river channel improvements will yield higher environmental benefits over the planned open channels. This study was able to present a clear and rational approach in the examination of overall environmental effects of SFMMs, which provides valuable insights that can be used by decision-makers and policy makers to improve the EIA practice and evaluation of projects in the Philippines.

    Urban floods from thunderstorms cause severe problems in Metro Manila due to road traffic. Using Light Detection and Ranging (LiDAR)-derived topography, flood simulations and anecdotal reports, the root of surface flood problems in Metro Manila is identified. Majority of flood-prone areas are along the intersection of creeks and streets located in topographic lows. When creeks overflow or when rapidly accumulated street flood does not drain fast enough to the nearest stream channel, the intersecting road also gets flooded. Possible solutions include the elevation of roads or construction of well-designed drainage structures leading to the creeks. Proposed solutions to the flood problem of Metro Manila may avoid paralyzing traffic problems due to short-lived rain events, which according to Japan International Cooperation Agency (JICA) cost the Philippine economy 2.4billionpesos/day.

    Many volcanoes worldwide are located near populated cities that experience monsoon seasons, characterised by shifting winds each year. Because of the severity of flood impact to large populations, it is worthy of investigation in the Philippines and elsewhere to better understand the phenomenon for possible hazard mitigating solutions, if any. During the monsoon season, the change in flow direction of winds brings moist warm air to cross the mountains and volcanoes in western Philippines and cause lift into the atmosphere, which normally leads to heavy rains and floods. Heavy southwest monsoon rains from 18-21 August 2013 flooded Metro Manila (population of 12 million) and its suburbs paralyzing the nation’s capital for an entire week. Called the 2013 Habagat event, it was a repeat of the 2012 Habagat or extreme southwest monsoon weather from 6-9 August, which delivered record rains in the mega city. In both the 2012 and 2013 Habagat events, cyclones, the usual suspects for the delivery of heavy rains, were passing northeast of the Philippine archipelago, respectively, and enhanced the southwest monsoon. Analysis of Doppler data, rainfall measurements, and Weather Research and Forecasting (WRF) model simulations show that two large stratovolcanoes, Natib and Mariveles, across from Manila Bay and approximately 70 km west of Metro Manila, played a substantial role in delivering extreme rains and consequent floods to Metro Manila. The study highlights how volcanoes, with their shape and height create an orographic effect and dispersive tail of rain clouds which constitutes a significant flood hazard to large communities like Metro Manila.

    We report concentrations, enrichment factors, and hazard indicators of 11 metals (Ag, As, Cd, Co, Cu, Fe, In, Mn, Ni, Pb, and Zn) in soil and dust surface matrices from formal and informal electronic waste (e-waste) recycling sites around Metro Manila, the Philippines, referring to soil guidelines and previous data from various e-waste recycling sites in Asia. Surface dust from e-waste recycling sites had higher levels of metal contamination than surface soil. Comparison of formal and informal e-waste recycling sites (hereafter, "formal" and "informal") revealed differences in specific contaminants. Formal dust contained a mixture of serious pollutant metals (Ni, Cu, Pb, and Zn) and Cd (polluted modestly), quite high enrichment metals (Ag and In), and crust-derived metals (As, Co, Fe, and Mn). For informal soil, concentration levels of specific metals (Cd, Co, Cu, Mn, Ni, Pb, and Zn) were similar among Asian recycling sites. Formal dust had significantly higher hazardous risk than the other matrices (p<0.005), excluding informal dust (p=0.059, almost significant difference). Thus, workers exposed to formal dust should protect themselves from hazardous toxic metals (Pb and Cu). There is also a high health risk for children ingesting surface matrices from informal e-waste recycling sites.

    Due to frequent antibiotic exposure, swine is now recognized as potential risk in disseminating drug-resistant Salmonella enterica strains. This study thus subjected 20 randomly selected S. enterica isolates from tonsil and jejunum with lymph node (JLN) tissues of swine slaughtered in Metro Manila, Philippines, to VITEK 2 antimicrobial susceptibility testing (AST). The test revealed all 20 isolates had resistance to at least one antimicrobial agent, in which highest occurrence of resistance was to amikacin (100%), cefazolin (100%), cefuroxime (100%), cefuroxime axetil (100%), cefoxitin (100%), and gentamicin (100%), followed by ampicillin (50%), and then by sulfamethoxazole trimethoprim (30%). Three multidrug-resistant (MDR) isolates were detected. The sole S. enterica serotype Enteritidis isolate showed resistance to 12 different antibiotics including ceftazidime, ceftriaxone, amikacin, gentamicin, and tigecycline. This study is the first to report worldwide on the novel resistance to tigecycline of MDR S. enterica serotype Enteritidis isolated from swine tonsil tissues. This finding poses huge therapeutic challenge since MDR S. enterica infections are associated with increased rate of hospitalization or death. Thus, continual regulation of antimicrobial use in food animals and prediction of resistant serotypes are crucial to limit the spread of MDR S. enterica isolates among hogs and humans. PMID:24724034

    Food poisoning outbreaks and livestock mortalities caused by Salmonella enterica are widespread in the Philippines, with hogs being the most commonly recognized carriers of the pathogen. To prevent and control the occurrence of S. enterica infection in the country, methods were used in this study to isolate and rapidly detect, differentiate, and characterize S. enterica in tonsils and jejuna with jejunal lymph nodes of swine slaughtered in four locally registered meat establishments (LRMEs) and four meat establishments accredited by the National Meat Inspection Services in Metro Manila. A total of 480 samples were collected from 240 animals (120 pigs from each type of meat establishment). A significantly higher proportion of pigs were positive for S. enterica in LRMEs (60 of 120) compared with meat establishments accredited by the National Meat Inspection Services (38 of 120). More S. enterica-positive samples were found in tonsils compared with jejuna with jejunal lymph nodes in LRMEs, but this difference was not significant. A PCR assay targeting the invA gene had sensitivity that was statistically similar to that of the culture method, detecting 93 of 98 culture-confirmed samples. Multiplex PCR-based O-serogrouping and H/Sdf I typing revealed four S. enterica serogroups (B, C1, D, and E) and six serotypes (Agona, Choleraesuis, Enteritidis, Heidelberg, Typhimurium, and Weltevreden), respectively, which was confirmed by DNA sequencing of the PCR products. This study was the first to report detection of S. enterica serotype Agona in the country.

    Abstract Seven species of Hydraenidae, Hydrophilidae and Elmidae are recorded from temporary freshwater habitats at the Ateneo de Manila University Campus in the metropolitan area of Manila, Philippines. They were identified as Enochrus (Lumetus) fragiloides d’Orchymont, Helochares (Hydrobaticus) lepidus d’Orchymont, Helochares (Helochares) pallens (MacLeay), Hydraena (Hydraenopsis) scabra d’Orchymont, Hydraena (Hydraenopsis) palawanensis Freitag & Jäch (new record for Luzon Island), Stenelmis sp. A further hydraenid species was unknown to science and is newly described: Hydraena (Hydraenopsis) ateneo Freitag, sp. n. Aedeagus, gonocoxite, spermatheca, and female tergite X are illustrated by computer-based line drawings. Habitus images of all three Hydraena Kugelann species recorded and a checklist of the Philippine Hydraena are provided. The presence of these seven species in the Ateneo campus is briefly discussed in regard to the area’s history. Measures to maintain and extend semi-natural islands of biodiversity in urban areas are suggested. PMID:24146550

    2009-01-01

    One of the potential solutions in social and environmental sustainability in municipal solid waste management (MSW) in Metro Manila is to combine community-based recycling and sound landfill management strategies. The marriage of the two puts importance on recycling as a source of livelihood while proper landfill management aims to improve the aesthetic and environmental quality of disposal facilities in urban areas. To do this, a social mapping of wastepickers, junkshops and local recycling practices needs to be undertaken and at the same time assess strategies of the national and local governments vis-à-vis existing laws on municipal solid waste. The case of Payatas controlled disposal facility was taken as a pilot study because it represents the general condition of disposal sites in Metro Manila and the social landscape that it currently has. In addition, a waste-to-energy (WTE) project has been established in Payatas to produce electricity from methane gas. Preliminary interviews with wastepickers show that development interventions in disposal sites such as WTE pose no opposition from host communities for as long as alternative livelihood opportunities are provided. Regulating the flow of wastepickers into the landfill has advantages like improved income and security. Felt needs were also articulated like provision of financial support or capital for junkshop operation and skills training. Overall, a smooth relationship between the local government and community associations pays well in a transitioning landfill management scheme such as Payatas.

    Wind energy is one of the best options for renewable energy such that, many researchers work on wind resource assessment, specifically using numerical weather prediction (NWP) model to forecast atmospheric behavior on a given domain. In addition, every combination of parameterization configuration influences wind assessment. At the same time, choosing the optimum vertical and horizontal resolution may affect its output and processing time. Regardless of available researches, most of them focuses on mid-latitude area but not in tropical areas like the Philippines. In the study, sensitivity analysis of Weather Research and Forecasting (WRF) model version 3.6.1 with 4 configurations was performed. The duration of the simulation was from January 1, 2014 00:00 to December 31, 2014 23:00. The parameters involved were horizontal resolution and vertical levels. Also, meteorological input data from NCEP Final Analysis with 1 degree resolution every 6 hours was used. For validation, wind speed measurements at 10 m height from NOAA Integrated Surface Database (ISD) were utilized, of which, the 3 weather stations are located in Manila, Science Garden and Ninoy Aquino International Airport (NAIA). The results show that increasing horizontal resolution from 4 km to 1 km have no significant increase to wind speed accuracy. In majority, higher vertical levels tend to increase its accuracy. Moreover, the model has higher accuracy during the rainy season and months of April and May. Overall, the model overestimated the observed wind speed but the diurnal cycle of wind speed follows all the simulation.

    This study evaluated a brief human rights-focused HIV community mobilization intervention for sex workers in the Philippines, a country with one of the fastest rising number of HIV cases worldwide. Five single-session group interventions to reduce sexual risk and increase HIV testing among 86 sex workers in Manila were evaluated with pre-post-test data via Wilcoxon's signed-ranks and Mann-Whitney tests. The 4-h intervention, Kapihan (August-November, 2013), integrated human rights with HIV skill-building. Demographic data, violence/trafficking victimization, human rights knowledge, and intentions to HIV test and treat were collected. Participants were median aged 23; female (69 %); had children (55; 22 % had 3+ children); used drugs (past 3 months: 16 %); sexually/physically abused by clients (66 %); 20 % street sex workers ever took an HIV test. Pre-post-test scores significantly improved in knowledge of HIV (z = -8.895, p < 0.001), reproductive health (z = -3.850, p < 0.001), human rights (z = -4.391, p < 0.001), ethical rights of research participants (z = -5.081, p < 0.001), and intentions to HIV test (z = -4.868, p < 0.001). Integrating human rights into HIV interventions may empower sex workers to address their health and human rights and test for HIV.

    The experiences and practices of household waste management of people in a barangay (village) in Manila, Philippines are documented. The data were gathered through an interview with household members using open-ended questions. Interviews were also conducted with garbage collectors as well as scavengers. Results showed that the households generated an average of 3.2 kg of solid waste per day, or 0.50 kg/capita/day. The types of wastes commonly generated are food/kitchen wastes, papers, PET bottles, metals, and cans, boxes/cartons, glass bottles, cellophane/plastics, and yard/garden wastes. The respondents segregate their wastes into PET bottles, glass bottles, and other waste (mixed wastes). No respondents perform composting. It is worth noting, however, that burning of waste is not done by the respondents. The households rely on garbage collection by the government. Collection is done twice daily, except Sundays, and household members bring their garbage when the garbage truck arrives. However, there are those who dump their garbage in nondesignated pick-up points, usually in a corner of the street. The dumped garbage becomes a breeding ground for disease-causing organisms. Some household respondents said that it is possible that the dumping in certain areas caused the dengue fever suffered by some of their family members. Mothers and household helpers are responsible for household waste management. Scavengers generally look for recyclable items in the dumped garbage. All of them said that it is their only source of income, which is generally not enough for their meals. They are also aware that their work affects their health. Most of the respondents said that garbage collection and disposal is the responsibility of the government. The results of the study showed that RA 9003, also known as the Ecological Solid Waste Management Act of 2000, is not fully implemented in Metro Manila.

    In 1988, former President Corazon Aquino created the Presidential Task Force on Traffic Management to formulate plans and programs to improve the traffic situation in Metro Manila and to address the emerging problem of air pollution and concern on renewable energy sources for transportation. The Task Force formulated the Metro Manila Traffic Improvement Plan (TRIP) which was approved by President Aquino for implementation. TRIP called for the development of a mass urban transport system, which included the expansion of the light rail transit system and the construction and improvement of the Metro Manila road network. Culled mainly from the TRIP proposals, the Updated Transport and Traffic Management Plan for Metro Manila (1993-1998) was developed through interagency discussions, public consultations, data collation and research work. This plan is directed towards the development of a more responsive public transport system, expansion of road network capacity, and improvement of traffic management and enforcement. Constraints may be present along the way but opportunities and potentials exist for the deliverance of daily commuters struggling to make a living.

    Using the solid waste management programmes of three barangays (the smallest unit of local government in the Philippines) in Quezon City, Metro Manila, as a case study, this research aimed to further the development of efficient organic waste recycling systems through the promotion of urban agricultural activities on green and vacant spaces. First, the quantity of organic waste and compost produced through ongoing barangay projects was measured. The amount of compost that could potentially be utilized on farmland and vacant land within the barangays was then identified to determine the possibility of a local recycling system. The results indicate that, at present, securing buyers for compost is difficult and, therefore, most compost is distributed to large neighbouring farm villages. However, the present analysis of potential compost use within the barangay demonstrates that a more local compost recycling system is indeed feasible.

    Sudden rises in sea water over and above astronomical tides due to an approaching storm are known as storm surges. The development of an early warning system for storm surges is imperative, due to the high threat level of these events; Typhoon Haiyan in 08 November 2013 generated storm surges that caused casualties of over 6,000. Under the Department of Science and Technology, the Nationwide Operational Assessment of Hazards (DOST - Project NOAH) was tasked to generate storm surge hazard maps for all the coastal areas in the Philippines. The objective of this paper is to create guidelines on how to utilize the storm surge hazard map as a tool for planning and disaster mitigation. This study uses the case of the hypothetical situation in which a tropical storm with an intensity similar to Typhoon Haiyan hits Metro Manila. This site was chosen for various reasons, among them the economic, political, and cultural importance of Metro Manila as the location of the capital of the Philippines and the coastal bay length of the area. The concentration of residential areas and other establishments were also taken into account. Using the Japan Meteorology Association (JMA) Storm Surge Model, FLO-2D flood modelling software and the application of other GIS technology, the impact of Haiyan-strength typhoon passing through Manila was analysed. We were able to identify the population affected, number of affected critical facilities under each storm surge hazard level, and possible evacuation sites. The results of the study can be used as the basis of policies involving disaster response and mitigation by city authorities. The methods used by the study can be used as a replicable framework for the analysis of other sites in the Philippines.

The image on the left was created using the best global topographic data set previously available, the U.S. Geological Survey's GTOPO30. In contrast, the much more detailed image on the right was generated with data from the Shuttle Radar Topography Mission, which collected enough measurements to map 80 percent of Earth's landmass at this level of precision.

    The city of Manila is on the eastern shore of Manila Bay at the right edge of the image. The large central plain to the north of the bay, irrigated by the Panpanga and Agno rivers, is the most important agricultural region in the Philippines. The Bataan Peninsula and volcanic Mt. Bataan at lower center along with the small island of Corregidor near the bottom edge became famous when the Allied forces made their last stand there during World War II. Dominating the upper left of the scene is 1,600 meter (5,249 foot) high Mt. Pinatubo, whose violent eruption on June 15, 1991, wrought widespread destruction on Luzon as well as injecting dust and gas into the atmosphere, which lowered global average temperatures for over a year.

    The image on the right combines two types of Shuttle Radar Topography Mission data. The image brightness corresponds to the strength of the radar signal reflected from the ground, while colors show the elevation measurements. Colors range from blue at the lowest elevations to brown and white at the highest elevations.

    For some parts of the globe, Shuttle Radar Topography Mission measurements are 30 times more precise than previously available topographical information, according to NASA scientists. Mission data will be a welcome resource for national and local governments, scientists, commercial enterprises, and members of the public alike. The applications are as diverse as earthquake and volcano, flood control, transportation, urban and regional planning, aviation

    Storm surge is the abnormal rise in sea water over and above astronomical tides due to a forthcoming storm. Developing an early warning system for storm surges is vital due to the high level of hazard they might cause. On 08 November 2013, Typhoon Haiyan generated storm surges that killed over 6,000 people in the central part of the Philippines. The Nationwide Operational Assessment of Hazards under the Department of Science and Technology was tasked to create storm surge hazard maps for the country's coastal areas. The research project aims to generate storm surge hazard maps that can be used for disaster mitigation and planning. As part of the research, the team explored a scenario wherein a tropical cyclone hits the Metro Manila with strength as strong as Typhoon Haiyan. The area was chosen primarily for its political, economic and cultural significance as the country's capital. Using Japan Meteorological Agency Storm Surge model, FLO2D flooding software, LiDAR topographic data, and GIS technology, the effects of a Haiyan-induced tropical cyclone passing through Metro Manila was examined. The population affected, number of affected critical facilities, and potential evacuation sites were identified. The outputs of this study can be used by the authorities as basis for policies that involve disaster risk reduction and management.

    A major source of nutrient load to periodically hypoxic Manila Bay is the urban nutrient waste water flow from humans and industries to surface water. In Manila alone, the population density is as high as 19,137 people/km2. A model based on a global point source model by Morée et al. (2013) was used to estimate the contribution of the population to nitrogen and phosphorus emissions which was then used in a water transport model to estimate the nitrogen (N) and phosphorus (P) loads to Manila Bay. Seven scenarios for 2050 were tested, with varying degrees and amounts for extent of sewage treatment, and population growth rates were also included. In scenario 1, the sewage connection and treatment remains the same as 2010; in scenario 2, sewage connection is improved but the treatment is the same; in scenario 3, the sewage connection as well as treatment is improved (70% tertiary); and in scenario 4, a more realistic situation of 70% primary treatment achieved with 100% connection to pipes is tested. Scenarios 5, 6, and 7 have the same parameters as 1, 2, and 3 respectively, but with the population growth rate per province reduced to half of what was used in 1, 2, and 3. In all scenarios, a significant increase in N and P loads was observed (varying from 27% to 469% relative to 2010 values). This was found even in scenario 3 where 70% of the waste water undergoes tertiary treatment which removes 80% N and 90% P. However, the lowest increase in N and P load into the bay was achieved in scenarios 5 to 7 where population growth rate is reduced to half of 2010 values. The results suggest that aside from improving sewage treatment, the continued increase of the human population in Manila at current growth rates will be an important determinant of N and P load into Manila Bay.

    This social science case study examines the sex trafficking of women and girls in Metro Manila through a public health lens. Through key informant interviews with 51 health care and anti-trafficking stakeholders in Metro Manila, this study reports on observations about sex trafficking in Metro Manila that provide insight into understanding of risk factors for sex trafficking at multiple levels of the social environment: individual (for example, childhood abuse), socio-cultural (for example, gender inequality and a "culture of migration"), and macro (for example, profound poverty caused, inter alia, by environmental degradation disrupting traditional forms of labor). It describes how local health systems currently assist sex-trafficking victims, and provides a series of recommendations, ranging from prevention to policy, for how health care might play a larger role in promoting the health and human rights of this vulnerable population.

    Dengue fever is a serious concern for Japanese people staying in Southeast Asia. In order to implement necessary prophylactic measures for dengue fever in this population, we investigated the characteristics of dengue fever among Japanese nationals living in Manila, Philippines. From 2012 to 2015, 175 Japanese expatriates were diagnosed with dengue fever at the medical clinic of the Japanese Association Manila, Inc. Most of the patients were employees of Japanese companies and their families and were long-term residents of Manila. Most patients were either <10 years or in their 30s to 40s. Two patients (1.1 %) were diagnosed with dengue hemorrhagic fever. No deaths due to dengue fever were reported. The reported number of patients with dengue fever has shown a decreasing trend: from 55 cases in 2012 to 53 in 2013, 31 in 2014, and 36 in 2015. The results of this survey could be useful for the development of effective dengue fever preventive measures such as health education and provision of information among not only Japanese but also other foreigners residing in endemic areas.

    The Sunda plate converges obliquely with the Philippine Sea plate with a rate of ~100 mm/yr and results in the sinistral slip along the 1300 km-long Philippine fault. Using GPS data from 1998 to 2013 as well as a block modeling approach, we decompose the crustal motion into multiple rotating blocks and elastic deformation associated with fault slip at block boundaries. Our preferred model composed of 8 blocks, produces a mean residual velocity of 3.4 mm/yr at 93 GPS stations. Estimated long-term slip rates along the Manila subduction zone show a gradual southward decrease from 66 mm/yr at the northwest tip of Luzon to 60 mm/yr at the southern portion of the Manila Trench. We infer a low coupling fraction of 11% offshore northwest Luzon and a coupling fraction of 27% near the subduction of Scarborough Seamount. The accumulated strain along the Manila subduction zone at latitudes 15.5°~18.5°N could be balanced by earthquakes with composite magnitudes of Mw 8.7 and Mw 8.9 based on a recurrence interval of 500 years and 1000 years, respectively. Estimates of sinistral slip rates on the major splay faults of the Philippine fault system in central Luzon increase from east to west: sinistral slip rates are 2 mm/yr on the Dalton fault, 8 mm/yr on the Abra River fault, and 12 mm/yr on the Tubao fault. On the southern segment of the Philippine fault (Digdig fault), we infer left-lateral slip of ~20 mm/yr. The Vigan-Aggao fault in northwest Luzon exhibits significant reverse slip of up to 31 mm/yr, although deformation may be distributed across multiple offshore thrust faults. On the Northern Cordillera fault, we calculate left-lateral slip of ~7 mm/yr. Results of block modeling suggest that the majority of active faults in Luzon are fully locked to a depth of 15-20 km. Inferred moment magnitudes of inland large earthquakes in Luzon fall in the range of Mw 7.0-7.5 based on a recurrence interval of 100 years.

Design: A descriptive cross-sectional study based on a review of data from household contact registries in local government unit (LGU) and non-government organisation (NGO) facilities during January-December 2012 in Manila and Quezon City. Free discussion sessions were also conducted among health-care workers. Results: Of 6161 children and adult household contacts listed in the LGUs and 1893 in the NGOs, 17% (n = 1086) in the LGUs and 95% (n = 1800) in the NGOs were evaluated. The yield of clinically diagnosed TB among children aged <15 years was 10.2% (127/1245) in the LGUs and 8.4% (63/752) in the NGOs. The yield of isoniazid preventive therapy (IPT) for those aged <5 years was 23.1% (124/537) in the LGUs and 28.0% (78/279) in the NGOs. The NGOs produced a high yield of IPT due to a better logistical system that ensured the availability of supplies and systematic home visits. Conclusion: Screening of household contacts in poor urban areas appears to be effective; it increased the number of children aged <15 years eligible for IPT and should be expanded as an intervention strategy for TB control in the Philippines.

    Failure of gonococcal infections to respond to 500 mg of ciprofloxacin or 400 mg of ofloxacin has been reported from Australia, the United Kingdom, and the United States. Recently, high rates of decreased susceptibility to the fluoroquinolones have been detected in penicillinase-producing Neisseria gonorrhoeae in the Republic of the Philippines. To assess the diversity of antimicrobial-resistant gonococcal strains isolated from female sex workers in Manila and Cebu City in the Republic of the Philippines in 1994. Isolates of N. gonorrhoeae isolated from 92 female sex workers in Manila (n = 28) and Cebu City (n = 64), respectively, were characterized by plasmid profile, auxotype/serovar class, and antimicrobial susceptibility profile. Plasmid-mediated resistance to penicillin or tetracycline was identified in 79.3% (73/92) of the isolates: penicillinase-producing N. gonorrhoeae (65/92; 70.7%), tetracycline-resistant N. gonorrhoeae (6/92; 6.5%), and penicillinase-producing/tetracycline-resistant N. gonorrhoeae (1/92; 1.1%). A beta-lactamase plasmid of 3.9 megadaltons was discovered. Of 54.3% (50/92) of strains resistant to nalidixic acid, 84% (42/50) of strains had minimum inhibitory concentrations of > or = 0.125 microgram/ml ciprofloxacin; penicillinase-producing N. gonorrhoeae (possessing the 3.05-, 3.2-, 3.9-, and 4.4-megadalton beta-lactamase plasmids, respectively) accounted for 68% (34/50) of these strains. In the Republic of the Philippines, gonococcal isolates resistant to penicillin or tetracycline accounted for 85.9% (79/92) of the isolates examined and included strains exhibiting resistance to fluoroquinolones. All gonococcal infections should be treated with antimicrobial therapies known to be active against all gonococcal strains to reduce the spread of strains exhibiting decreased susceptibilities to fluoroquinolones.

    Hypoxia in Manila Bay, Philippines was previously reported during the northeast monsoon (dry season) in February 2010. In this study, four more field surveys of the same 31 stations were conducted in July 2010, August 2011 and 2012 (wet season, southwest monsoon), and February 2011 (dry season, northeast monsoon). During the wet season, bottom hypoxia spread northward towards the coast with dissolved oxygen (DO) ranging from 0.12 to 9.22 mg/L and the bay-wide average reaching 2.10 mg/L. Nutrient levels were elevated, especially near the bottom where dissolved inorganic nitrogen reached 22.3 μM (July 2010) and phosphorus reached 5.61 μM (August 2011). High nutrient concentrations often coincided with low near-bottom DO content. Our work builds on the preliminary assessment of hypoxia in Manila Bay, the importance of repeated temporal studies, and shows hypoxia to prevail significantly during the southwest monsoon (wet season) when increased freshwater discharge caused strong water column stratification.

    The first 14C-based paleoseismic study of an active fault in the Philippines shows that a right-lateral fault on the northeast edge of metropolitan Manila poses a greater seismic hazard than previously thought. Faulted hillslope colluvium, stream-channel alluvium, and debris-flow deposits exposed in trenches across the northern part of the west Marikina Valley fault record two or three surface-faulting events. Three eroded, clay-rich soil B horizons suggest thousands of years between surface faulting events, whereas 14C ages on detrital charcoal constrain the entire stratigraphic sequence to the past 1300-1700 years. We rely on the 14C ages to infer faulting recurrence of hundreds rather than thousands of years. Minimal soil development and modern 14C ages from colluvium overlying a faulted debris-flow deposit in a nearby stream exposure point to a historic age for a probable third or fourth (most recent) faulting event.

    Dengue is the most important mosquito-borne disease in the Philippines, especially in Metropolitan Manila where communities are socially and economically diverse, and city governments struggle to provide basic services such as continuously available, piped water supply to residents. We examined responses to introducing water container management to control dengue vectors in two diverse communities in Masagana City: Village A (gated community) and Village B (informal settlers community). The roll out of the intervention was carried out by the study team, dengue control personnel and local health workers (BHWs). A behavioural change framework was used to describe the community responses to the introduction of a new vector control intervention - household water container management. Although, the desired outcome was not achieved during the study's timeline, observation on processes of behaviour change underscored the importance of understanding the social nature of the urban communities, often overlooked structures when dengue control program and researchers introduce new dengue control interventions.

    The objective of this study was to assess the occupational exposure of jeepney drivers to selected volatile organic compounds (VOCs) in Manila, Philippines. Personal sampling was conducted on 15 jeepney drivers. Area sampling was conducted to determine the background VOC concentration in Manila as compared to that in a rural area. Both personal and area samples were collected for 5 working days. Samples were obtained using diffusive samplers and were analyzed for 6 VOCs (benzene, toluene, ethylbenzene, m,p-xylene and o-xylene) using gas chromatography. Results showed that the average personal exposure concentration of jeepney drivers was 55.6 (± 9.3), 196.6 (± 75.0), 17.9 (± 9.0), 72.5 (± 21.1) and 88.5 (± 26.5) μg/m3 for benzene, toluene, ethylbenzene, m,p-xylene and o-xylene, respectively. The urban ambient concentration was 11.8 (± 2.2), 83.7 (± 40.5) and 38.0 (± 12.1) μg/m3 for benzene, toluene and o-xylene, respectively. The rural ambient concentration was 14.0 (± 6.0) and 24.7 (± 11.9) μg/m3 for toluene and o-xylene, respectively. The personal samples had significantly higher (p<0.05) concentrations for all selected VOCs than the urban area samples. Among the area samples, the urban concentrations of benzene and toluene were significantly higher (p<0.05) than the rural concentrations. The personal exposures for all the target VOCs were not significantly different among the jeepney drivers. PMID:19218755

    Significant levels of potentially carcinogenic bromate were measured in chlorinated tap drinking water in Metropolitan Manila, Philippines, using an optimized ion-chromatographic method. This method can quantify bromate in water down to 4.5 μg l⁻¹ by employing a postcolumn reaction with acidic fuchsin and subsequent spectrophotometric detection. The concentration of bromate in tap drinking water samples collected from 21 locations in cities and municipalities within the 9-month study period ranged from 7 to 138 μg l⁻¹. The average bromate concentration of all tap drinking water samples was 66 μg l⁻¹ (n = 567), almost seven times greater than the current regulatory limit in the country. The levels of bromate in other water types were also determined to identify the sources of bromate found in the distribution lines and to further uncover contaminated sites. The concentration of bromate in water sourced from two rivers and two water treatment plants ranged from 15 to 80 and 12 to 101 μg l⁻¹, respectively. Rainwater did not contribute bromate in rivers but decreased bromate level by dilution. Groundwater and wastewater samples showed bromate concentrations as high as 246 and 342 μg l⁻¹, respectively. Bromate presence in tap drinking water can be linked to pollution in natural water bodies and the practice of using hypochlorite chemicals in addition to gaseous chlorine for water disinfection. This study established the levels, occurrence, and possible sources of bromate in local drinking water supplies.

    Dengue fever (DF) and leptospirosis are serious public problems in tropical regions, especially in Manila, the Philippines. In attempting to understand the causes of DF and leptospirosis seasonality, meteorological factors have been suspected, but quantitative correlation between seasonality and meteorological factors has not been fully investigated. In this study, we investigated correlation of temporal patterns of reported numbers of laboratory-confirmed cases of both DF and leptospirosis with meteorological conditions (temperature, relative humidity, rainfall) in Manila. We used time-series analysis combined with spectral analysis and the least squares method. A 1-year cycle explained underlying variations of DF, leptospirosis and meteorological data. There was a peak of the 1-year cycle in temperature during May, followed by maxima in rainfall, relative humidity and number of laboratory-confirmed DF and leptospirosis cases. This result suggests that DF and leptospirosis epidemics are correlated not only with rainfall but also relative humidity and temperature in the Philippines. Quantifying the correlation of DF and leptospirosis infections with meteorological conditions may prove useful in predicting DF and leptospirosis epidemics, and health services should plan accordingly.

    We examine interseismic coupling of the Manila subduction zone and fault activity in the Luzon area using a block model constrained by GPS data collected from 1998 to 2015. Estimated long-term slip rates along the Manila subduction zone show a gradual southward decrease from 90-100 mm/yr at the northwest tip of Luzon to 65-80 mm/yr at the southern portion of the Manila Trench. We provide two block models (models A and B) to illustrate possible realizations of coupling along the Manila Trench, which may be used to infer future earthquake rupture scenarios. Model A shows a low coupling ratio of 0.34 offshore western Luzon and continuous creeping on the plate interface at latitudes 18-19°N. Model B includes the North Luzon Trough Fault and shows prevalent coupling on the plate interface with a coupling ratio of 0.48. Both models fit GPS velocities well, although they have significantly different tectonic implications. The accumulated strain along the Manila subduction zone at latitudes 15-19°N could be balanced by earthquakes with composite magnitudes of Mw 8.8-9.2, assuming recurrence intervals of 500-1000 years. GPS observations are consistent with full locking of the majority of active faults in Luzon to a depth of 20 km. Inferred moments of large inland earthquakes in Luzon fall in the range of Mw 6.9-7.6 assuming a recurrence interval of 100 years.

    Healthcare facilities in low- and middle-income countries, including the Philippines, face substantial challenges in achieving effective infection control. Early stages of interventions should include efforts to understand perceptions held by healthcare workers who participate in infection control programs. We performed a qualitative study to examine facilitators and barriers to infection control at an 800-bed, private, tertiary hospital in Manila, Philippines. Semi-structured interviews were conducted with 22 nurses, physicians, and clinical pharmacists using a guide based on the Systems Engineering Initiative for Patient Safety (SEIPS). Major facilitators and barriers to infection control were reported for each SEIPS factor: person, organization, tasks, physical environment, and technology and tools. Primary facilitators included a robust, long-standing infection control committee, a dedicated infection control nursing staff, and innovative electronic hand hygiene surveillance technology. Barriers included suboptimal dissemination of hand hygiene compliance data, high nursing turnover, clinical time constraints, and resource limitations that restricted equipment purchasing. The identified facilitators and barriers may be used to prioritize possible opportunities for infection control interventions. A systems engineering approach is useful for conducting a comprehensive work system analysis, and maximizing resources to overcome known barriers to infection control in heavily resource-constrained settings.

  3. Application of ANP and DEMATEL to evaluate the decision-making of municipal solid waste management in Metro Manila.

    2009-09-01

    A municipal solid waste management (MSW) expert group was consulted in order to mirror how government officials might reach an effective solution regarding municipal solid waste management in Metro Manila. A critical issue regarding this is how the expert group can better evaluate and select a favorable MSW management solution using a series of criteria. MSW management solution selection is a multiple criteria decision-making (MCDM) problem, which requires the consideration of a large number of complex criteria. A robust MCDM method should consider the interactions among these criteria. The analytic network process (ANP) is a relatively new MCDM method which can deal with all kinds of interactions systematically. The Decision Making Trial and Evaluation Laboratory (DEMATEL) not only can convert the relations between cause and effect of criteria into a structural model, but also can be used as a way to handle the inner dependences within a set of criteria. Hence, this paper applies an effective solution based on a combined ANP and DEMATEL method to assist the expert group evaluating different MSW management solutions. According to the results, the best solution is for each city to have its own type of thermal process technology and resource recovery facility before landfill rather than entering a joint venture with enterprises or going into build-operate-transfer projects in order to be able to construct thermal process technologies and resource recovery facilities.

    Historical trends of the accumulation of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) in a typical tropical Asian environment were investigated using radio-dated sediment cores from Manila Bay, the Philippines and from the upper Gulf of Thailand. Vertical profiles indicated earlier usage of PCBs than of PBDEs which coincided with their industrial production. The increasing concentrations of total PBDEs and PCBs toward the surface suggested an increased consumption of PBDEs; and possible leakage of PCBs from old machineries into the aquatic environment in recent years. Current input of PCBs to the catchment of Manila Bay was supported by the analyses of air samples and plastic resin pellets. The vertical profiles of total PBDEs in the cores (i.e., rapidly increasing concentrations corresponding to the mid-1980s until mid-1990s, followed by a decrease until the early 2000s, and increasing again toward the surface) likely corresponded to the rapid economic growth in Asia in the 1990s, the Asian financial crisis in 1997, and the economic recovery since early 2000s. BDE-209 was predominant especially on the surface layers. BDEs 47 and 99 generally decreased toward the surface, reflecting the phase-out of the technical penta-PBDE products and the regulation by the Stockholm Convention in recent years. Increasing ratios of BDE-202/209, 206/209, 207/209 and decreasing % of BDE-209 down the core layers may provide evidence for the anaerobic debromination of BDE-209 in the sediment cores. Inventories in ng/cm(2) of total PCBs were higher than total PBDEs (92 vs. 34 and 47 vs. 11 in the Philippines; 47 vs. 33 in Thailand). However, the doubling times indicated faster accumulation of total PBDEs (6-7 years) and BDE-209 (6-7.5 years) than of PCBs (8-11 years). Furthermore, the temporal increase in BDE-209 was comparable to or faster than those reported in other water bodies around the world. © 2013.

  5. Global sea-level rise is recognised, but flooding from anthropogenic land subsidence is ignored around northern Manila Bay, Philippines.

    2006-03-01

    Land subsidence resulting from excessive extraction of groundwater is particularly acute in East Asian countries. Some Philippine government sectors have begun to recognise that the sea-level rise of one to three millimetres per year due to global warming is a cause of worsening floods around Manila Bay, but are oblivious to, or ignore, the principal reason: excessive groundwater extraction is lowering the land surface by several centimetres to more than a decimetre per year. Such ignorance allows the government to treat flooding as a lesser problem that can be mitigated through large infrastructural projects that are both ineffective and vulnerable to corruption. Money would be better spent on preventing the subsidence by reducing groundwater pumping and moderating population growth and land use, but these approaches are politically and psychologically unacceptable. Even if groundwater use is greatly reduced and enlightened land-use practices are initiated, natural deltaic subsidence and global sea-level rise will continue to aggravate flooding, although at substantially lower rates.

    Ultra high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) determination of four paraben preservatives (methyl, ethyl, propyl and butyl) and two antimicrobial agents (triclosan and triclocarban) belonging to personal care products (PCPs) in 20 species of fish from Manila Bay (Philippines) was performed. Detection of PCPs with greater frequency indicates the ubiquitous contamination of Manila Bay. Concentrations of total paraben were one order of magnitude higher than the antimicrobials in almost all fish, except in Stolephorus indicus and Leiognathus equulus. A positive correlation was observed between parabens concentration and fish length (r = 0.31-0.49; p<0.05 to <0.001) and fish weight (r = 0.28-0.49; p<0.05 to <0.001), but not for the antimicrobials. The estimated dietary exposure values of the four parabens in the Philippines through fish is four orders of magnitude lower than the acceptable daily intake (ADI) of 10mg/kg/day, but the values of antimicrobials are just half of the ADI of TCS. To our knowledge, this is the first report of PCPs contamination in fish from Philippines.

    The determinants of the use of family planning, prenatal care, childhood immunizations and oral rehydration salts (ORS) were studied with survey data of 8000 women in Metro Cebu, the Philippines. Polytomous logistic regression methods were used. The level of maternal education was the most consistent and important determinant of use of these four health services in both urban and rural areas. For example, the estimated odds of using modern contraception increased by six and eleven per cent for each additional year of schooling in urban and rural strata respectively. Economic status and access to service variables had less consistent patterns: women's work status, for example, was associated only with contraceptive use.

    The effect of temperature on the risk of mortality has been described in numerous studies of category-specific (e.g., cause-, sex-, age-, and season-specific) mortality in temperate and subtropical countries, with consistent findings of U-, V-, and J-shaped exposure-response functions. In this study, we analyzed the relationship between temperature and mortality in Manila City (Philippines), during 2006-2010 to identify the potential susceptible populations. We collected daily all-cause and cause-specific death counts from the Philippine Statistics Authority-National Statistics Office and the meteorological variables were collected from the Philippine Atmospheric Geophysical and Astronomical Services Administration. Temperature-mortality relationships were modeled using Poisson regression combined with distributed lag nonlinear models, and were used to perform cause-, sex-, age-, and season-specific analyses. The minimum mortality temperature was 30 °C, and increased risks of mortality were observed per 1 °C increase among elderly persons (RR: 1.53, 95% CI: 1.31-1.80), women (RR: 1.47, 95% CI: 1.27-1.69), and for respiratory causes of death (RR: 1.52, 95% CI: 1.23-1.88). Seasonal effect modification was found to greatly affect the risks in the lower temperature range. Thus, the temperature-mortality relationship in Manila City exhibited an increased risk of mortality among elderly persons, women, and for respiratory-causes, with inherent effect modification in the season-specific analysis. The findings of this study may facilitate the development of public health policies to reduce the effects of air temperature on mortality, especially for these high-risk groups.

Satellite-based observations can serve as an alternative source of information if ground-based measurements are not readily available. The data provided by satellites must be validated to ensure reliability and effectiveness of use. In this study, the Integrated Multisatellite Retrievals for GPM (IMERG) Final Run half-hourly product is aggregated to 1-day resolution and compared to interpolated ground measurements derived from sixteen ground stations in Metro Manila for the duration of July 1 - July 8 2014. The space considered in this study is the area within 14.4° - 14.8° latitude and 120.9° - 121.2° longitude, subdivided into twelve 0.1° x 0.1° boxes. The aggregated satellite product is also directly compared to the readings provided by the individual ground stations. The comparisons are done by taking a normalized root-mean-square error between two datasets. The results show that IMERG performed relatively well over the whole Metro Manila area from July 1 to 4 with normalized RMSE values of 0.44 to 0.89 and performed badly from July 5 to 8 with error values of 1.03 up to 4.72. July 3 and July 4 have the highest average amounts of rainfall of 19.475 mm and 19.320 mm and lowest amounts of normalized RMSE error of 0.72 and 0.44, respectively. July 5 had the lowest average amount of rainfall of 1.625 mm and the highest amount of normalized RMSE error of 4.72. The time series of normalized RMSE for each box is also analyzed. The minimum and maximum RMSE values in this analysis are 0.01 and 1.79, respectively. However, onset of typhoon (July 5) can produce normalized RMSE value of 31.77. This can be attributed to the fact that satellite data may observe high water content in the atmosphere but this is not necessarily reflected from ground measurements due to strong winds.

    We sought to determine the epidemiology of carbapenem-resistant Enterobacteriaceae and to investigate the emergence of carbapenem-resistant Klebsiella pneumoniae in two teaching hospitals in Manila, Philippines. We screened 364 Enterobacteriaceae for carbapenem resistance between 2012 and 2013 and detected four carbapenem-resistant K. pneumoniae isolates from three different patients. We used whole genome sequencing to determine the antibiotic resistance profiles and confirmed the presence of carbapenemase genes by multiplex PCR. We used multilocus sequence typing and PCR-based replicon typing to genetically characterize the carbapenem-resistant isolates. The carbapenemase gene blaNDM was detected in K. pneumoniae isolates from two patients. The first patient had ventilator-associated pneumonia and lumbar shunt infection from K. pneumoniae ST273 carrying blaNDM-7. The second patient had asymptomatic genitourinary colonization with K. pneumoniae ST656 carrying blaNDM-1. The third patient had a gluteal abscess with K. pneumoniae ST1 that did not carry a carbapenemase gene, but did carry blaDHA-1, blaOXA-1, and blaSHV-1. In this study, we report the first cases of blaNDM-carrying pathogens in the Philippines and add to the growing evidence of the worldwide spread of ST273 and NDM-7, a more efficient carbapenem hydrolyzer than NDM-1.

    This project investigates the relationship between lactation and female sexual functioning and relationship commitment among partnered women in urban Manila. Previous literature suggests that the time after giving birth is often rife with lower sexual functioning and relationship dissatisfaction. Given the important role of caregiving by multiple individuals in humans, the current cross-sectional study suggests that female sexuality may decline immediately after giving birth but then may increase afterwards. Non-cycling, breastfeeding (n = 86); cycling, breastfeeding (n = 48); and nulliparous, regularly cycling (n = 105) women were recruited from neighborhood health centers in Manila to complete questionnaires that assessed sexual functioning and relationship satisfaction, along with demographic variables. Cycling, breastfeeding women report the highest sexual functioning scores and commitment scores. Females undergoing life history trade-offs between mating effort and parenting effort during the postpartum phase may employ a strategy in which they continue investment both in their offspring and in a romantic relationship. Variations in self-reported sexual functioning, level of commitment in a relationship, and love toward her current partner may indicate that breastfeeding women engage in sexual activities as part of a relationship maintenance strategy. Cultural and life history factors will serve as a framework for the findings. The current findings suggest women in Manila may experience a post-birth increase in sexual functioning that may be higher than pre-pregnancy levels. Future studies should incorporate a longitudinal component or a memory recall on pre-pregnancy and post-birth sexual functioning levels.

    Concentrations of lead (Pb), copper (Cu), zinc (Zn), and cadmium (Cd) were evaluated in the sediments, roots and leaves of a mangrove species (Avicennia marina) in Las Piñas-Parañaque Critical Habitat and Ecotourism Area (LPPCHEA), Manila Bay. The concentrations showed a general pattern of Zn > Pb > Cu > Cd in sediments, Cu > Pb > Zn > Cd in roots and Cu > Zn > Pb > Cd in leaves. The trace metal concentrations in both sediments and plant tissues were below contamination threshold levels. Based on computed bioaccumulation indices, A. marina could be used for the phytostabilization and phytoextraction of Cu and Cd. The LPPCHEA mangrove ecosystem is an ecologically important ecosystem that will limit the spread of trace metals to the surrounding environment.

    Aedes aegypti (L.) is an efficient vector for arboviral diseases such as dengue. The wings of Ae. aegypti has been extensively studied in order to investigate population heterogeneity and structure by utilizing a landmark based geometric morphometrics (GMs) approach. The aim of this study was to examine and assess the wing geometry of Ae. aegypti in Metropolitan Manila. In total, 312 Ae. aegypti mosquitoes were collected from 98 sampling points using a mosquito light-trap from May 2014 to January 2015. A complete coverage of the wing was achieved by removing wing scales with chemical and physical treatment, leading to identification of 26 landmarks. Geometric morphometric analyses were employed and the spatial distance pattern was estimated using isolation by distance (IBD) and spatial autocorrelation (SA). The results of the GM analyses revealed population heterogeneity and structuring in Ae. aegypti populations for both sexes using principal component and canonical variate analyses respectively. Moreover, IBD and SA only detected significant spatial structure in male Ae. aegypti populations while female population structures were homogeneous throughout the geographical area. The newly modified wing preparation procedure was able to capture a complete coverage of the wings of Ae. aegypti, thus providing a stronger separation power for very close populations in an urban area. It is also noteworthy that the results of IBD and SA supported the findings of GM in the population structuring of male and female Ae. aegypti. The outcome of the study increases our understanding of the vector, which would be useful in developing effective control strategies.

    Rats are known to be the most important reservoirs and transmission sources of leptospirosis. However, the status of leptospirosis in the Philippines regarding reservoirs and transmission remains unknown. A survey was conducted in Metro Manila and Laguna that analyzed samples obtained from 106 rats. Using the microscopic agglutination test, we found that 92% of rat serum samples were positive for anti-Leptospira antibodies; the most common infecting serovars were Manilae, Hebdomadis, and Losbanos. On the basis of pulsed-field gel electrophoresis and gyrase B gene sequence analyses, four groups of rat kidney isolates were found: L. interrogans serovar Manilae, serovar Losbanos, and serogroup Grippotyphosa, and L. borgpetersenii serogroup Javanica. Most isolates were lethal after experimental infection of golden Syrian hamsters. Results showed that these four Leptospira serovars and serogroups are circulating among rats, and that these animals may be one of the possible transmission sources of leptospirosis in the Philippines.

    This study determines the prevalence of tobacco use among graduating Public Health students at the College of Public Health, University of the Philippines Manila. It also describes the exposure to environmental tobacco smoke, attitudes, behaviors and smoking cessation training of students. This study used a descriptive cross-sectional study design, adapting a standard questionnaire, pretested and administered to 52 Bachelor of Science in Public Health (BSPH) students at the College of Public Health, University of the Philippines Manila. Data generated from the survey were encoded using Epi Info version 3.5.4 and analyzed using Stata version 12. The prevalence of smoking among 4th year BSPH students was 5.8 % (current smokers). In the past 7 days, respondents have been exposed to secondhand smoke (44 % where they live; 79 % in places other than where they live). Majority were aware of the official policy on smoking ban in school, however, 80 % said that the policy is not enforced. Majority had favorable attitudes in terms of banning tobacco sales to adolescents, banning advertising of tobacco products, banning smoking in restaurants, discos/bars/pubs and enclosed public places. Majority of the respondents also believed that health professionals should get specific training on cessation techniques, that they do serve as role models, and that they have a role in giving advice about smoking cessation. More than three-quarters (76.9 %) of students said that health professionals who smoke are less likely to advise patients to quit. Most of the graduating students learned about the dangers of smoking, importance of obtaining tobacco use history, and providing educational support materials in their public health education but only a few received formal training about smoking cessation approaches. The implementation of the no-smoking policy of the university must be revisited. Smoking cessation approaches should be incorporated in the public health curriculum and the role

    This discussion of the Philippines focuses on the following: the people; geography; history; government; political conditions; economy (agriculture, mining, industry, and foreign trade); defense; foreign relations; and relations between the US and the Philippines. In 1982 the population was estimated at 51.6 million with an annual growth rate of 2.4%. The infant mortality rate was 59/1000 (1982), and life expectancy was 64 years (1981). The Philippine people are mostly of Malay stock, descended from the Indonesians and Malays who migrated to the islands long before the Christian era. The most significant ethnic minority group is the Chinese, who have played an important role in commerce since the 9th century, when they first came to the islands to trade. About 90% of the people are Christian. The Philippine Archipelago extends about 1770 kilometers north to south along the southeastern rim of Asia, forming a land chain between the Pacific Ocean on the east and the South China Sea on the west. The archipelago consists of some 7100 islands and islets. The history of the Philippines may be broken down into 4 distinct phases: the pre Spanish period, the Spanish period (1521-1898); the American period (1898-1946); and the years since independence (1946-present). A new constitution, to replace that of 1935, was completed by a constitutional convention in November 1972 and was proclaimed in effect in January 1973. The 1973 constitution provided for a parliamentary system, initially with extensive powers vested in a prime minister. Major amendments adopted in 1981 revised the system to make the president head of government. From independence of 1972, the Philippines practiced relatively traditional constiutional democracy. In addition to more moderate, legitimate opposition, the government has been opposed by 2 insurgencies, whose roots predated martial law, and by some urban terrorism. The Philippine economy grew rapidly during the period of rehabilitation and expansion

    The Philippines is an archipelago of 7100 islands and islets, 11 of which compose about 95% of the total area and population. The majority of the Filipinos are descendants of Indonesians and Malays. Approximately 90% of the population are Christian with the majority of the remaining 10% being Moslems. In the 1960s, the annual population growth rate was roughly 3%, but it fell to 2.4% in the late 1970s and was still 2.4% in 1985. In 1970, President Marcos implemented an official family planning policy to reduce the high growth rate and thereby stimulate economic development. A population commission coordinates family planning efforts. Both the Spanish (1521-1898) and the United States (1898-1946) have ruled the Philippines with a brief occupation by the Japanese (1942-1945). The US assisted in the reconstruction of the economy following World War II and continues to maintain and operate military bases. Further, from 1946-1986, the Philippines has received $3.7 billion in economic and military assistance from the US. The government operated under a constitutional democracy from 1946-1972, but in 1972 President Marcos declared martial law. In 1981, martial law ended and Marcos called for a presidential election. After winning the election, he called for an amendment of the 1972 constitution making him, rather than the prime minister, the head of government. Even though martial law ended in 1981, the Marcos government retained its wide powers to arrest and detain anyone. In February 1986, popular support backed by a peaceful civilian-military uprising brought Corazon Aquino to the Presidency. In the mid 1980s a severe economic recession hit the Philippines with the real GNP growth rate ranging from -5.3%-0%. The Philippines have diplomatic relations with the south east Asian nations, many East Bloc nations, the US, China, Cuba, and the Soviet Union.

    The Philippines' Clean Water Act was developed to protect the country's remaining water resources by institutionalizing mechanisms to monitor, regulate, and control human and industrial activities which contribute to the ongoing environmental degradation of marine and freshwater resources. Approximately 70 participants attended the Philippine Parliamentarians' Conference on Water Resources, Population and Development held December 3-4, 1997, at the Sulo Hotel in Quezon City. Participants included the legislative staff of the members of the House of Representatives and the Senate, Committee Secretaries of the House and Senate, and government and nongovernmental organization officials. Following the opening programs, panel discussions were held on the role of nongovernmental organizations as legitimate monitors of governments' activities; the need to evaluate water sector assessment methods, water policy and strategy, and water legislation standards; and waste water treatment and sewerage systems used in households and industries. The following issues were raised during the conference's open forum: the need to implement new methods in water resource management; the handling of water for both economic and social purposes; the need to implement guidelines, policies, and pricing mechanisms on bottled water; regulating the construction of recreational facilities such as golf courses; and transferring watershed rehabilitation from the Department of Environment and Natural Resources to local water districts. A declaration was prepared and signed by the participants at the close of the conference.

    The environmental occurrence of polybrominated diphenyl ethers (PBDEs) has been a subject of concern for the past decade because they are persistent, bioaccumulative, and toxic. These compounds have been listed as persistent organic pollutants (POPs) by the Stockholm Convention and are expected to disperse in the global environment even after their use and production. While the occurrence of PBDEs has been well characterized in environmental and biological samples from North America, Europe, and some Asian countries (i.e. China, Japan, and Korea), there is a scarcity of available data in developing Asian countries, such as the Philippines. Examination of PBDE contamination in the Philippine environment is particularly important because regulations have only recently been implemented on the production and use of PBDEs in this country. Additionally, the Philippines receives e-waste from Western countries, which is becoming a major source of organic contaminants in the tropical Asian regions. Ultimately, the Philippines may be a hot spot for contributing to on-going global PBDE pollution due to long-range atmospheric transport. This paper presents a review of the available literature on PBDEs in both environmental and biological samples collected from the Philippines. It is also intended to provide an overview on the levels and congener profiles of PBDEs in samples from the Philippines and to compare these data with other Asian countries. New data are presented on PBDE occurrence and congener profiles in fish commonly consumed by Filipinos and in particulate matter samples collected in Metro Manila, the capital of the Philippines. Both studies contribute to the available knowledge of PBDEs in the Philippines. We aim to stress the importance of future studies in countries receiving e-wastes, such as the Philippines, and suggest what future directions might be taken to enhance the available data on the presence of PBDEs in the Philippine environment.

    Objective To evaluate the validity and reliability of the Philippines (Tagalog) Short Form 36 Health Survey version 2 (SF-36v2®) standard questionnaire among Filipinos residing in two cities. Study Design and Setting The official Philippines (Tagalog) SF-36v2 standard (4-week recall) version was pretested on 30 participants followed by formal and informal cognitive debriefing. To obtain the feedback on translation by bilingual respondents, each SF-36v2 question was stated first in English followed by Tagalog. No revisions to the original questionnaire were needed except that participants thought it was appropriate to incorporate "po" in the instructions to make it more polite. Face-to-face interviews of 562 participants aged 20-50 years living in two barangays (villages) in the highly urbanized city of Makati City (Metro Manila) and in urban and rural barangays in Tanauan City (province of Batangas) were subsequently conducted. Content validity, item level validity, reliability and factor structure of the SF-36v2 (Tagalog) were examined. Results Content validity of the SF-36v2 was assessed to be adequate for assessing health status among Filipinos. Item means of Philippines (Tagalog) SF-36v2 were similar with comparable scales in the US English, Singapore (English and Chinese) and Thai SF-36 version 1. Item-scale correlation exceeded 0.4 for all items except the bathing item in PF (correlation: 0.31). In exploratory factor analysis, the US two-component model was supported. However, in confirmatory factor analysis, the Japanese three-component model fit the Tagalog data better than the US two-component model. Conclusions The Philippines (Tagalog) SF-36v2 is a valid and reliable instrument for measuring health status among residents of Makati City (Metro Manila) and Tanauan City (Province of Batangas).

    Spanish merchant ships, called Manila Galleons, made the round-trip between the Philippine Islands and the ports on the west coast of what is now Mexico, almost every year for the 250-yr period between 1565 and 1815. The log books of these galleons contained weather information which was thought to be of value in the study of the historical climatology of the tropical and mid-latitude areas of the Pacific Ocean. A search was made for the log books of the Manila Galleons to determine how many are still extant and the nature of the weather data that they contained. The search was made with the assistance of expert historians and paleographers who ware experienced in searching archives where the log books wore thought to be on file. The following archives were searched: the Museo Naval in Madrid, Spain; the Archivo General do Simancas in Simancas, Spain; Archiyo De lndias in Seville, Spain; Archivo General do la Nación in Mexico City, Mexico; and the National Archives in Manila, The Philippine Islands. Only sixteen log books were on file In the archives in Madrid and Seville. All of the logs that wore found ware from the period between 1766 and 1808. The inevitable conclusions that were reached were that log books for some of the earlier voyages may never have been written and that most of the log books that were written were either physically lost or were lost due to the ravages of time, moisture, insects or war.

    This study was carried out to document the genotypes of Acanthamoeba present in contact lens cases from 50 randomly selected contact lens wearers living in Quezon City, Metro Manila, Philippines. Acanthamoeba species were isolated from eight (16%) in 50 contact lens cases examined. We analyzed partial 18S ribosomal DNA (Rns) sequences of the eight isolates and found that the sequence differences were sufficient to distinguish the genotypes. After the isolates were genotyped, using the Basic Local Alignment Search Tool program, their phylogenetic positions relative to known Acanthamoeba isolates were determined. The model-based (GTR+Gamma+Iota) neighbor-joining, maximum likelihood, and Bayesian inference analyses, as well as the non-model-based maximum parsimony analysis were used. Results showed that of the eight isolates, six were Rns genotype T5 while two were Rns genotype T4. This present study indicates that genotype T5 is also a common contaminant in contact lens storage cases.

    Recent studies have reported Trichomonas tenax as a cause of pleuropulmonary infections in humans. In this study, sputum and vaginal swab samples were collected from patients suffering from respiratory ailments in Rodriguez, Rizal and sex workers attending the social hygiene clinics in Angeles City in Pampanga, Mandaluyong City and Pasay City in Metro Manila, Philippines, respectively. DNA was extracted from samples and the 18S rRNA gene was amplified and sequenced. Phylogenetic trees were constructed using neighbor-joining, maximum-likelihood, maximum parsimony, and Bayesian inference analyses. Results showed that the new primer sets successfully amplified T. tenax from 14 sputum samples and Trichomonas vaginalis from 19 vaginal swab samples. Consequently, all isolates clustered with high bootstrap support and posterior probability values to their respective reference strains in the phylogenetic tree. Thus, the genus Trichomonas formed a highly supported clade with T. vaginalis in the first clade and T. tenax in the second clade. These findings conclude that T. vaginalis is solely present in the genito-urinary tract of females and that T. tenax can be found in the respiratory tract of humans. To our knowledge, this is the first report of detection and identification of T. tenax from sputum samples in the Philippines. However, further studies are still needed to determine the pathogenicity of this organism in humans. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Human respiratory syncytial virus (HRSV) is a major cause of acute lower respiratory tract infections in infants and children worldwide. We performed molecular analysis of HRSV among infants and children with clinical diagnosis of severe pneumonia in four study sites in the Philippines, including Biliran, Leyte, Palawan, and Metro Manila from June 2012 to July 2013. Nasopharyngeal swabs were collected and screened for HRSV using real-time polymerase chain reaction (PCR). Positive samples were tested by conventional PCR and sequenced for the second hypervariable region (2nd HVR) of the G gene. Among a total of 1,505 samples, 423 samples were positive for HRSV (28.1%), of which 305 (72.1%) and 118 (27.9%) were identified as HRSV-A and HRSV-B, respectively. Two genotypes of HRSV-A, NA1 and ON1, were identified during the study period. The novel ON1 genotype with a 72-nucleotide duplication in 2nd HVR of the G gene increased rapidly and finally became the predominant genotype in 2013 with an evolutionary rate higher than the NA1 genotype. Moreover, in the ON1 genotype, we found positive selection at amino acid position 274 (p<0.05) and massive O- and N-glycosylation in the 2nd HVR of the G gene. Among HRSV-B, BA9 was the predominant genotype circulating in the Philippines. However, two sporadic cases of GB2 genotype were found, which might share a common ancestor with other Asian strains. These findings suggest that HRSV is an important cause of severe acute respiratory infection among children in the Philippines and revealed the emergence and subsequent predominance of the ON1 genotype and the sporadic detection of the GB2 genotype. Both genotypes were detected for the first time in the Philippines. PMID:26540236

    This study examines the relationship between interreligious contact and negative attitudes towards the religious out-group. It uses unique survey data collected by the authors among Christian and Muslim students in Maluku and Yogyakarta (Indonesia) and Mindanao and Metro Manila (the Philippines). Even after taking self-selection effects into account, interreligious friendships reduce negative attitudes towards the religious out-group. However, casual interreligious contact increases negative out-group attitudes. Also individuals who experienced interreligious violence have more negative out-group attitudes than those without such experience. The experience of interreligious violence has no influence on the effect of interreligious friendships but it further deteriorates the relationship between casual interreligious contact and out-group attitudes. Perceived group threat is an important mechanism explaining the effects of both positive and negative interreligious contact. [125].

    Blastocystis sp. is a commonly reported enteric protistan parasite in faecal specimens with a worldwide distribution afflicting both humans and a wide range of animals. The aim of this study is to characterize the subtypes (STs) of Blastocystis sp. isolates from asymptomatic individuals in an urban community in Pateros, Metro Manila, Philippines. The 600-bp small subunit ribosomal RNA (SSU rRNA) barcoding region of Blastocystis sp. isolates was amplified and sequenced using the primers RD5 and BhRDr. Subtypes were identified by uploading the sequences onto the Basic Local Alignment and Search Tool (BLAST) websites, the Blastocystis Subtype (18S) and Sequence Typing (MLST) Database and by construction of a phylogenetic tree. Twenty-nine (29) out of 35 individuals were detected positive for Blastocystis sp. ST3 is the most common among the three STs detected (65.5%), followed by ST1 (31.0%) and ST4 (3.44%). This study showed that DNA barcoding can serve as a helpful tool to investigate the diversity of Blastocystis sp. in the Philippines.

    The Seminar on Adolescent Pregnancy and the First 1000 Days (the Philippine Situation) was held in Metro Manila on September 2013. The objectives were to: 1) describe the current nutrition and health status of Filipino adolescent females, including those pregnant and lactating; 2) discuss existing programs that address their concerns; and 3) identify gaps in existing knowledge and programs, and ways to address these gaps. Adolescent pregnancy rates had increased from 8% in 2003 to 10% in 2008. In 2008, more than 35 percent of pregnant women below 20 years old were considered nutritionally-at-risk. Iodine deficiency and anaemia were major health problems in both pregnant and lactating women of all ages. While government programs exist to address the needs of pregnant women, none were geared towards meeting the specific needs of pregnant adolescents. Studies are needed to find ways to improve adolescent health and to effectively prevent and deal with unwanted pregnancies among adolescents. Recommendations include 1) developing adolescent-friendly health centers, information and education materials to increase reproductive and health awareness among youth and health workers, 2) examining the psychosocial and nutritional factors that determine birth outcomes and nutritional status of pregnant/non-pregnant adolescents, 3) examining adolescent growth patterns following delivery, 4) evaluating the im-pact of current programs and interventions geared towards improving adolescent and maternal health, and more importantly, 5) identifying the underlying reasons for the continued rise in adolescent pregnancy in the country.

    The recently established Master of Science in Genetic Counseling (MSGC) program serves a vital role in implementing and expanding genetic counseling services in the Philippines. Currently, only eight clinical geneticists practice in the Philippines, a country of approximately 94 million people, which yields a clinical-geneticist-to-population-density ratio of 1:11,750,000. The MSGC program was created to train health care providers to become crucial members of medical genetics teams being formed to meet increasing patient and healthcare provider demands. In 2011, the Board of Regents approved our proposed curriculum at the Department of Pediatrics College of Medicine, University of the Philippines Manila. As we relate how the Philippines began its efforts to implement the program and attempted to overcome the challenges the program faced, we hope we can provide an example to those interested in creating a similar MSGC program in other low-income and middle-income countries.

    1980-06-01

    Seismic and volcanic activity in the Philippine Islands was examined in an attempt to decipher the tectonics of this region. Several new fault plane solutions for shallow, intermediate, and deep focus earthquakes were determined. This study has revealed the presence of a zone of eastward underthrusting in the western Philippines which is well developed near Negros Island. Fault plane solutions of several shallow earthquakes in the western Philippines show thrust faulting with slip vectors toward east or northeast. As active eastward subduction of the Eurasian plate is also taking place along the Manila trench near west central Luzon, it suggests that the underthrusting of the Eurasian plate may have occurred at one time along the western Philippines from Taiwan to Sulawesi in the Molucca Sea. Subduction has ceased along sections where continental crust is present. This interpretation is consistent with the geology and gravity anomalies in the area. Near the eastern Philippines the westward subduction of the Philippine Sea plate occurs (1) along the Philippine trench and (2) in a localized zone near the western edge of the Benham rise. The Philippine Islands are therefore flanked in the east and west by active but disjointed subduction systems. Left lateral strike slip faulting has been deduced near one end of several of these active trench systems and suggests movement on transverse features. Seismic activity on the Philippine fault is concentrated in the zone between 10°N and 15°N and appears to be due to stresses generated by opposing movements of the Philippine and Eurasian plates which are not released in underthrusting. Fault plane solutions of shallow earthquakes associated with the Philppine fault show left lateral strike slip motion consistent with field observations. Our study suggests that the extent and magnitude of earthquake activity on the Philippine fault forms one component of movement between the Eurasian plate and the Philippine Sea plate.

    The trade of secondhand electrical and electronic equipment (EEE) from developed to developing countries has become a growing environmental issue owing to concerns about improper recycling of these goods in developing countries. We followed a 12-m cargo container of cathode-ray-tube color TVs exported from Japan to the Philippines in February 2008. We surveyed the number of TVs damaged in transport, as well as the number of malfunctioning TVs from this shipment. In addition, we present the results of interviews with 113 Filipino consumers who intended to buy secondhand EEE at nine secondhand shops in Metro Manila. Approximately 3% of the imported TVs were damaged upon arrival. The importer sold some of the units directly to local dealers, and kept the rest to repair, refurbish and resell. Approximately 40% of the imported TVs malfunctioned and needed repair in addition to basic reconditioning. Most interviewees indicated that they prefer to buy secondhand EEE because the prices are lower than those of brand-new products. Consumers indicated that they planned on using the product for an average of about 5years, but the actual period of use may be lower. Most end-of-life EEE in the Philippines is dismantled and recycled by unregulated companies and untrained individuals in markets or near landfill sites, and it is clear that a proper collection system and treatment methods are needed for e-waste. In addition to the material flow of secondhand TVs, we also discuss several economic aspects and appropriate control measures of the international reuse of secondhand TVs.

    We investigated the high-resolution heavy metal pollution history of Manila Bay using heavy metal concentrations and Pb isotope ratios together with (210)Pb dating to find out the effects of environmental regulations after the 1990 s. Our results suggested that the rate of decline in heavy metal pollution increased dramatically from the end of the 1990 s due to stricter environmental regulations, Administrative Order No. 42, being enforced by the Philippines government. The presented data and methodology should form the basis for future monitoring, leading to pollution control, and to the generation of preventive measures at the pollution source for the maintenance of environmental quality in the coastal metropolitan city of Manila. Although this is the first report of a reduction in pollution in Asian developing country, our results suggest that we can expect to find similar signs of pollution decline in other parts of the world as well.

    A massive landslide devastated the community of Barangay Guinsaugon, Municipality of St. Bernard, Southern Leyte Province, Philippines, at about 10:30 local time on 17 February. The landslide occurred along the steep fault scarp of the Philippine Fault Zone (PFZ) (Figure 1a), a large and active tectonic structure that traverses the entire length of the Philippines [Allen, 1962]. Barangay Guinsaugon is located at the foot of the scarp, directly in the path of the downward moving mass of earth. As of 24 February, the landslide caused 122 confirmed deaths; 1,328 people still are missing. To assist in the search and rescue operations that followed the landside, a team of geologists and physicists from the University of Philippines (UP-Diliman, Quezon City) and Ateneo de Manila University conducted an investigation of this area on 21-25 February. The UP-Ateneo team provided technical advice on the geology, which included the identification of the type and characteristics of the landslide.

  5. Two-dimensional Numerical Models of Accretionary Wedges Deformation in Response to Subduction and Obduction: Evidence from the Middle Part of the Manila Trench

    The Manila Trench is located at the eastern boundary of the South China Sea (SCS). It was created by the subduction of the South China Sea Plate beneath the Philippine Sea Plate since the early Neogene, and also influenced by the northwestern movement of the Philippine Sea Plate. There is wide discussion whether the dual-subduction and widespread seamounts in the South China Sea would have play important roles in the 'S-shaped' geometry and the different diving angle along the Manila Trench. Multi-beam tectono-geomorphological studies on the accretionary wedges have suggested that: (1) the stress direction of the subduction along the middle part of the Manila Trench, between 17o and 18 o N, is NW55 o; (2) The Manila Trench is actually caused by obduction due to the northwestern movement of the Philippine Sea Plate. Although the NW 55 o stress direction has been supported by detailed analysis on the trend of the folds, thrust faults, extension fractures and large sea-floor canyon, its obduction-origin is purely based on regional structure. Here we use 2D numerical modeling experiments to investigate the deformation style of accretionary wedge in response to the seamounts subduction and obduction, and provide new insights into the mechanism responsible for the Luzon obduction along the Manila Trench. Our preliminary results show that: (1) the accretionary wedge is eroded faster in subduction model; (2) the velocity field direction of the slab differs in two models at the beginning of seamount subduction, which is vertical in obduction model, but oblique in subduction model; (3) both sides of the accretionary wedge deform strongly in subduction model, whereas in obduction model only the leading edge shows intensive deformation. Further modelling will focus on other parts of the Manila Trench with different slab age and subduction velocity to see their tectonic influences on the accretionary wedges.

    Torrential and sustained rainfall from tropical cyclones, monsoons, and thunderstorms frequently impact the Philippines. In order to predict, assess, and measure storm impact, it is imperative to have a reliable and accurate monitoring system in place. In 2011, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) established a weather radar network of ten radar devices, eight of which are single-polarization S-band radars and two dual-polarization C-band radars. Because of a low-density hydrometeorological monitoring networks in the Philippines, calibration of weather radars becomes a challenging, but important task. In this study, we explore the potential of scrutinizing the calibration of ground radars by using the observations from the Tropical Rainfall Measuring Mission (TRMM). For this purpose, we compare different TRMM level 1 and 2 orbital products from overpasses over the Philippines, and compare these products to reflectivities observed by the Philippine ground radars. Differences in spatial resolution are addressed by computing adequate zonal statistics of the local radar bins located within the corresponding TRMM cell in space and time. The wradlib package (Heistermann et al. 2013; Heistermann et al. 2015) is used to process the data from the Subic S-band single-polarization weather radar. These data will be analyzed in conjunction with TRMM data for June to August 2012, three months of the wet season. This period includes the enhanced monsoon of 2012, locally called Habagat 2012, which brought sustained intense rainfall and massive floods in several parts of the country including the most populated city of Metro Manila.

    Blastocystis has been considered as the most common intestinal parasite in humans and has an augmented impact on public health. However, the prevalence of this parasite in the Philippines has not been determined. To contribute to a better understanding of the epidemiology of this infection, a cross-sectional study aimed at providing the first documented data on the prevalence and correlates, sociodemographic factors, hygiene practices, source of water supply, and dog ownership, associated with Blastocystis infection was carried out in randomly selected communities at Pateros, Metro Manila. Fecal samples from respondents were collected and cultured in diphasic agar medium for 3-7 days and examined using light microscopy. Of the 1,271 respondents, 12.98% (95% CI: 11.13-14.83) were detected positive for Blastocystis. Among the correlates of Blastocystis infection, dog ownership was found significantly associated as confirmed by multivariate analysis. Therefore, this factor should be considered in information to create awareness about Blastocystis and to prevent and control Blastocystis infection in particular and diarrheal diseases in general. Further studies using molecular approaches to distinguish subtype and to determine genetic characteristics of isolates from humans and dogs are recommended to analyze their relationship and provide more conclusive evidence of cross-transmission.

  10. Earthquake-induced crustal gravitational potential energy change in the Philippine area

    2013-04-01

    The crustal gravitational potential energy change (ΔGPE) caused by earthquakes in the Philippine area from January 1976 to November 2011 was estimated in this study. The active convergence between the Philippine Sea Plate and the Sundaland-Eurasian margin is reflected by the greatest gains in GPE along the Philippine, Negros and Cotabato trenches, whereas the Manila Trench is covered by a GPE loss pattern. Although the Philippine Mobile Belt (PMB) itself is actually affected by the ongoing collision and subduction processes, almost the entire Philippine Fault Zone is dominated by GPE loss, revealing a slightly extensional environment along the fault. The time evolution of the cumulated ΔGPE for different segments along the Philippine archipelago shows distinct patterns. Due to the numerous large underthrusting events that have occurred along the Philippine Trench, the cumulated ΔGPE is regularly increasing in its most southern segment. However, in the middle segments, where the Palawan Block enters into collision with the PMB, the increase in cumulated ΔGPE is relatively small. In the most northern segment, where the North Luzon is located, a decrease of cumulated ΔGPE demonstrates that the seismic characteristic of the Manila Trench is dissimilar from other subduction systems in the world. We suggest that the collision of both the Palawan Block and the Benham Rise with the PMB promotes the rotation of the PMB and facilitates the northward escape of the northeastern Luzon, resulting in a decrease of cumulated ΔGPE in the northern Philippines.

    We quantify along-trench variations in plate flexural bending along the Manila trench in the South China Sea. A 3-D interpreted flexural deformation surface of the subducting South China Sea Plate was obtained by removing from the observed bathymetry the effects of sediment loading, isostatically-compensated topography based on gravity modeling, age-related lithospheric thermal subsidence, and residual short-wavelength features. We analyzed flexural bending of 21 across-trench profile sections along the Manila trench and then calculated five best-fitting tectonic and plate parameters that control the flexural bending for each of the across-trench profile sections. Results of analysis revealed significant along-trench variations: The trench relief of the Manila trench varies from 0.8 to 2.2 km, trench-axis vertical loading (-V0) from -0.4x1012 to 1.21x1012 N/m, and axial bending moment (-M0) from 0.005x1017 to 0.6x1017 N. The effective elastic plate thickness seaward of the Manila outer-rise region (TeM) ranges from 30 to 40 km, while that trench-ward of the outer-rise (Tem) ranges from 11 to 30 km. This corresponds to a reduction in Te of 26-63% for the Manila trench. The transition from TeM to Tem occurs at a breaking distance of 50-120 km from the Manila trench axis. The axial vertical loading, bending moment, and the effective elastic thickness of the Manila trench are much smaller than the Mariana trench (Zhang et al., 2014). The contrast in the flexural bending between the Mariana and Manila trenches might be related to the difference in the ages of the subducting plates and other tectonic variables.

    The Philippine family planning movement has been in existence for 25 years. The Catholic Church, however, has launched a smear campaign against it with the shibboleths of antichild, antifamily, antilife, and pro-abortion that had to be countered by the association. At the Pro-Life's First Training Congress on Love, Life, and Family held in 1995 at the country's oldest Catholic university in Manila (University of Santo Tomas), charges were leveled against it and the International Planned Parenthood Federation as owners of multinational companies that manufacture infant formulas, contraceptives, and abortion machines. At the IPPF Members' Assembly in 1995 this anti-family planning campaign escalated with charges that the IPPF was the agent of free sex, promiscuity, and low morality. All this in the face of IPPF's strong commitment to reproductive rights embodied in the Cairo and Beijing conference concluding documents on reproductive health. The President of the Philippines also addressed this meeting and voiced his support for family planning as an integral part of national development. The major issues in this arena are the gender relations between men and women; prevailing cultural norms and beliefs; lack of information and education; inadequate health care delivery; and poverty. In this climate Pro-Life, Philippines and Human Life International are outspoken in their 1996-98 advocacy campaign to: 1) capture key local government positions and promote their anti-FP agenda; 2) to undertake grassroots education through the Church's Family Life Apostolate; and 3) to campaign for the removal of population education currently being introduced in public schools and replace them with anti-FP and anti-population control education modules. This campaign poses a major challenge for the Philippine FP organization to work toward: 1) changing the knowledge, attitudes, and practices of women and couples toward FP; 2) changing the knowledge, attitudes, and practices of decision

    It has been widely studied on the complexity tectonic structure in the active Taiwan orogenesis, since the converging between the Philippine Sea plate (PSP) and the Eurasian plate (EU) along with the Manila subduction zone extended from the Philippine to offshore the southern Taiwan and the Ryukyu subduction zone in the east. Considering the separate contribution of the crust and the mantle lithosphere to the topography, we try to examine the mantle lithosphere buoyancy (Hm) behavior from the northern Manila subduction zone to the active collision in Taiwan region. In this study, we present several Hm profiles across the northern Manila subduction zone and the Taiwan island. In order to calculate the Hm, the crust structures are constrained by the forward gravity modeling, in which the density is provided from the multi-channel seismic data and on land seismic data (thanks to the Taiwan Integrated Geodynamic Research (TAIGER) project). The result shows that the Hm across the northern Manila subduction zone displays apparent undulations, and undulates more drastic approaching the north end of the subduction zone. It implies that the plate coupling between the PSP and the EU here is weak. The Hm across the southern Taiwan undulates still, but the amplitudes are smaller with relative gentle undulations. This reflects the contribution from the slab underneath while the initial collision occurs in south Taiwan. Into the central Taiwan, the Hm pattern behaves undulating mild comparing with that across the subduction zone because the slab structure effects not obvious. Besides, the Hm in the central Taiwan primarily is affects by both the thickening crust and high elevation caused by the strong lateral external compression stress.

    This paper examined socio-structural factors of consistent condom use among female entertainment workers at high risk for acquiring HIV in Metro Manila, Quezon City, Philippines. Entertainers, aged 18 and over, from 25 establishments (spa/saunas, night clubs, karaoke bars), who traded sex during the previous 6 months, underwent cross-sectional surveys. The 143 entertainers (42% not always using condoms, 58% always using condoms) had median age (23), duration in sex work (7 months), education (9 years), and 29% were married/had live-in boyfriends. In a logistic multiple regression model, social-structural vs. individual factors were associated with inconsistent condom use: being forced/deceived into sex work, less manager contact, less STI/HIV prevention knowledge acquired from medical personnel/professionals, not following a co-workers' condom use advice, and an interaction between establishment type and alcohol use with establishment guests. Interventions should consider the effects of physical (force/deception into work), social (peer, manager influence), and policy (STI/HIV prevention knowledge acquired from medical personnel/professionals) environments on consistent condom use.

    The Philippines ranks eighth among 27 priority countries for multidrug-resistant TB (MDR-TB). To describe a model of public-private partnership in MDR-TB management. An exploratory study of integrating MDR-TB management initiated in private-public mix DOTS into the National TB Programme (NTP). Recognising that MDR-TB was a threat to DOTS, the Tropical Disease Foundation initiated MDR-TB management in 1999. An official mandate for the integration of MDR-TB services into the NTP was issued by the Department of Health in 2008. With an increased government budget augmented by support from the Global Fund to Fight AIDS, Tuberculosis and Malaria, 1294 MDR-TB patients were placed on treatment from 1999 to 2008. The treatment success rate improved from 64% in 1999 to 75% in 2005. There are now five MDR-TB treatment centres with 181 treatment sites in Metro Manila, and three culture centres. People trained include 12 master trainers, 31 trainers, 25 treatment centre and 381 treatment site staff. Mainstreaming into the NTP of this unique model of MDR-TB management through a dynamic public-private collaboration can be considered best practice in implementation science of an evidence-based intervention leading to change in health care policy and practice.

    To assess the prevalence of sex work and its associations with substance use among female bar/spa workers in the Philippines (N = 498), workers from 54 bar or spa venues in Metro Manila (2009–2010) were surveyed on demographics, drug/alcohol use, abuse history, and sex work. Their median age was 23 years and 35% engaged in sex work. Sex work was independently associated with methamphetamine use (19% vs 4%; adjusted odds ratio [AOR] =2.9, 95% confidence interval [CI] = 1.3–6.2), alcohol use with patrons (49% vs. 27%;AOR = 1.9, 95% CI = 1.1–3.4), and alcohol intoxication during sex (50% vs. 24%; AOR = 2.0, 95% CI = 1.2–3.5), but inversely associated with daily alcohol use (13% vs. 16%;AOR = 0.2, 95% CI = 0.1–0.5). Additional significant covariates included sexual abuse history, younger age, and not having a higher education. Findings suggest that interventions with sex workers in bars and spas should focus on methamphetamine use, alcohol use contexts, and violence victimization, to better meet the needs of this population.

    We present a comprehensive crustal deformation model for the Philippine Mobile Belt, based on a newly available suite of geodetic data from a dense nationwide network of newly observed and previously published continuous and campaign GPS sites in the Philippines, collected by PHIVOLCS and Indiana University. We use elastic block models constrained by known fault geometries, observed GPS observations and focal mechanism solutions to invert for an estimate of block rotations, fault coupling, and intra-block deformation. In our preferred model, the Philippine Mobile Belt can be represented by at least 12 independently moving rigid tectonic blocks, separated by active faults and subduction zones. We observe rapid convergence along the Manila Trench, which decreases progressively southwards, from > 100 mm/yr at around 20°N, to less than 20 mm/yr near its southern termination at Mindoro Island reflecting the ongoing collision between Mindoro and the Palawan block. Along the Philippine Trench, we observe ~50 mm/yr of oblique convergence, with the convergence changing from nearly westward in the south to NW near its northern termination. Slip rates along the Philippine fault vary from ~10 - 40 mm/yr, trending subparallel to the fault trace. In northern Luzon, Philippine Fault splays accommodate transpressional strain. The Central Visayas block experiences convergence with the Sundaland block along the Sulu Trench and the Mindoro-Palawan collision zone. Mindanao Island in the southern Philippines is dominated by east-verging subduction along the Cotabato Trench, and strain partitioning in eastern Mindanao along the southern Philippine Fault and Philippine Trench. We examine the spatial variation of subduction zone coupling along the Manila and Philippine trenches and examine their contribution to earthquake potential, through dynamic modeling of subduction-zone creeping and locked segments.

    The Manila trench is the boundary between the South China Sea (SCS) of Eurasian Plate (EU) and Philippine Sea Plate (PSP). The east subducting of SCS is a ceased rifting oceanic crust. To the north, the subduction is obscured and transits to collision extended to the Taiwan orogenesis. The Taiwan Integrated Geodynamics Research (TAIGER) project has implemented several offshore multichannel seismic (MCS) reflection and wide-angle seismic experiments to model the velocity structure of the incipient arc-continental collision. Amongst, along two trench perpendicular transects (MGL0905_23, 25) are associated with ocean bottom seismometer (OBS) deployed in the northern Manila trench. The transect MCS data and tomographic velocity structure provide well constraint on the recognition between the crust and mantle lithosphere that helps to reconstruct synthetic density structure to fit the observation gravity data. The synthetic gravity result along two transects also show that there exists an anomalous high density (~2.97 g/cm3) mass beneath the accretionary prism in the leading edge of overriding plate; however, unfortunately, the MCS and OBS data have no resolution there. Meanwhile, the buoyancies of crust (Hc) and mantle lithosphere (Hm) can be calculated associated with the residual topography based on the isostatic equilibrium. According to the contribution of Hm, the estimation of the plate coupling effect can be approached. Combining two transects data across the northern Manila trench and one profile across the Hengchun Peninsula in southern Taiwan (T29-33, TAICRUST project), a sequence from subduction to collision of plate coupling effect can therefore be evaluated, and also offers the opportunity to examine the lithospheric structure variation in the zone between Taiwan and northernmost Manila trench.

    The Philippine Fault, which extends some 1,400 km through the length of the Philippine archipelago, represents one of the world's major strike-slip fault systems. We investigate the role of the fault in accommodating oblique convergence and strain partitioning along the Philippine plate boundary zone. Oblique subduction between the Philippine Sea Plate and the Eurasian plate is accommodated by near-orthogonal subduction along both the west-dipping Philippine Trench and the east-dipping Manila Trench, and by arc- parallel shear along the PF. We investigate the changing nature of slip along the fault, from northern Luzon through the central Philippines, using topography and satellite imagery, seismicity and earthquake mechanisms, and measurements from a regional GPS network in Luzon to identify active fault traces, investigate slip rates and directions, and degree of coupling along the fault. Inversion of GPS velocities and earthquake focal mechanisms suggests present-day slip rates along the PF ranging from ~22 - 36 mm/yr in the Central Visayas and ~10 - 40 mm/yr in Luzon, largely parallel to the trace of the fault. Our inversion suggests that within Luzon, the fault is segmented into a southern segment (from 12° to 14°N) associated with rift-related features in southwestern Luzon's Macolod Corridor, a central segment (from 15°-16°N) associated with nearly pure strike-slip deformation, and a series of northern splays (from 16°-17.5°N) that accommodate transpressional deformation as the fault extends into Luzon's Cordillera Central. Further north, the deformation scheme again changes to transtensional motion along the Northern Cordillera Fault. The inversion also suggests variations in coupling along the fault interface, ranging from 58% in the central Luzon segment, to nearly fully coupled on its northern and southern segments. Variations in fault motion and coupling may be a consequence of geometric changes associated with arc- continent collisions taking

To evaluate the costs and benefits of a 3-dose immunisation schedule in Manila, Philippines. Government and societal perspectives. A cost-benefit analysis based on a birth cohort of 100,000 children. The state of health of the cohort with and without a Hib immunisation programme was modelled over a 5-year period. A survey of medical records of patients with Hib in Manila provided data on the extent and cost of sequelae following infection. A 3-dose Hib vaccination programme given at ages 2, 3 and 4 months. The model predicted that vaccinating children against Hib meningitis would prevent 553 cases per year in a birth cohort of 100,000, at a cost of 56,200 Philippine pesos (PHP) [$US1,605; 1998 exchange rate] per case (base case assumptions of 90% vaccine efficacy rate, 95 per 100,000 Hib incidence rate, 85% vaccination coverage). Results from the cost-benefit analyses indicated that the saving to the government would be around PHP39 million ($US1.11 million), and the saving to society would be PHP255 million ($US7.28 million). There would be a positive economic benefit for the Philippine government and for the Filipino society if a Hib vaccination programme was introduced in Manila.

    Mayon volcano is the most active volcano in the Philippines, located just north of the coastal town of Legaspi in southern Luzon about 325 km southeast of Manila. Mayon is a near-perfect cone; its steep, forested slopes look rather like a bull's eye when viewed from above. For scale, Mayon's circular footprint is about 16 km in diameter. This photograph was taken from the Space Shuttle on April 8, 1997. At the time the photo was taken, Mayon sported a steam plume from the summit. The lighter (non-forested) regions that radiate from the summit to the southern slopes are flows from eruptions that have occurred over the past twenty-five years. The current eruption, which started June 24, 2001, is sending flows down the southeast slope in the general direction of Legaspi. Image STS083-747-88 was provided by the by the Earth Sciences and Image Analysis Laboratory, Johnson Space Center.

  6. Tertiary arc rifting in northern Luzon, Philippines

    1994-06-01

    The North Luzon terrane (NLT), comprising the section of Luzon north of the Philippine Fault, is one of the largest arc terranes in the Philippine Archipelago. Numerous features suggest that the NLT is a late Oligocene to early Miocene analogue for the processes in the modern intra-arc rift zone at the northern end of the Mariana Trough. First, the NLT has bifurcating magmatic arcs sharing similar magmatic histories. These include the Northern Sierra Madre (NSM) and Cordillera Central (CC) magmatic arcs, which are separated by the Cagayan basin but which are linked in the Caraballo Range to the south. The rock record indicates that the NSM, CC, and Caraballo Ranges were active arcs in late Eocene to late Oligocene time. Second, seismic reflection and well data indicate that the Cagayan basin formed by extensional faulting in late Oligocene to early Miocene time. Third, alkalic arc magmatism, recognized to be a precursor of intra-arc rifting in modern settings, occurred at the juncture of the NSM and CC arcs in late Oligocene to early Miocene time. Fourth, oceanic crust, represented by the Itogon ophiolite, formed at the southwestern end of the Cagayan basin in late Oligocene to early Miocene time. Major and trace element chemistry show that the Itogon sheeted dikes have tholeiitic arc and backarc basin basalt affinities. The rock record and geophysical offshore data suggest that the NLT was developing in an island arc system above the subducting West Philippine plate in late Eocene time. Rifting occurred in the island arc from late Oligocene to early Miocene time but did not mature into backarc spreading, most likely because of the collision of the Benham Rise, a basaltic rise in the West Philippine basin, with the NLT. The arc rifting in the NLT may be another manifestation of the extensional tectonism that affected most of Southeast Asia in late Oligocene to early Miocene time, during which the South China and Southeast Sulu basins formed.

    Objective To explore factors associated with trafficking (deceptive/coercive entry to sex trade) among female bar/spa entertainers who traded sex in the Philippines. Method Female bar/spa entertainers who traded sex in the past 6 months were recruited from 25 bar/spa venues in Metro Manila (April 2009–January 2010) and assessed via cross-sectional survey data collection for HIV-risk-related socio-structural factors associated with deceptive/coercive entry into the sex trade. The study employed hierarchical linear modeling. Results Of 166 bar/spa entertainers assessed, 19 (11.4%) reported being deceived/coerced (i.e. trafficked) into their first jobs. Trafficking history was independently associated with current drug use (adjusted odds ratio [AOR] 2.05; 95% confidence interval [CI] 1.00–3.97) decreased availability of condoms at venues for entertainers (AOR 0.18; 95% CI 0.05–0.71) and, conversely, increased peer support for practicing safer sex behaviors (AOR 3.08; 95% CI 1.63–5.09). Those deceived/coerced into their positions were more likely than non-trafficked women to have been recruited by an agency who came to their rural province (AOR 12.07; 95% CI 1.77-82.25) as opposed to getting the job from advertisement (AOR 0.10; 95% CI 0.02–0.65) or a friend/acquaintance (AOR 0.02; 95% CI 0.00–0.48). Conclusion The findings have implications for designing interventions to prevent and target trafficked women in the Philippines who may be more vulnerable to substance use and, potentially, HIV infection.

  8. Philippines: street children, children at risk.

    PubMed

    Almost 2 million of Manila's 2.5 million children younger than 15 years old live on or below the poverty line. 75,000 of these children live on the streets after having run away from home or being abandoned. They beg, steal, scavenge for food, and sell newspapers, cigarettes, and leis. About 20,000 of the street children prostitute themselves. It is these latter children and adolescents who are at particular risk of HIV infection. Studies in the Philippines indicate that 91% of reported HIV infections are among individuals aged 15-44, the male/female infection ratio is one to one, the transmission rate is 45%, and the most common mode of transmission is through heterosexual intercourse. The high incidence of child sexual abuse and child prostitution in the Philippines would suggest that there are a significant number of children and adolescents under age 15 who are infected with HIV. Caritas Manila has developed an information, education, and communication program for HIV/AIDS prevention focusing upon individuals who have direct influence upon and are in direct contact with people: clergy, religious and civic associations, educators, and social and health workers. Caritas has also to a limited extent reached out directly to populations at risk, while collaborating with human rights advocacy groups and networking with other children-oriented agencies in the interest of providing resources to street children. Efforts must be made to protect the rights of children and provide them with an environment conducive to their growth and development. The author notes how off-duty policemen in Manila help real estate developers forcibly eject the poor from their shelters to clear the way for the construction of new infrastructure without concern for the legal processes and requirements in the humane and peaceful relocation of the homeless poor. Many women and children are hurt and killed in the process. It has also been reported that off-duty policemen in Rio de Janeiro

    Background Social and structural influences of condom negotiation among female sex workers (FSWs) remain understudied. This study assesses environmental and individual factors associated with condom negotiation among FSWs at high risk for acquiring HIV in a large urban setting of Metro Manila, Philippines. Methods Female bar/spa workers (N = 498), aged 18 and over, underwent interview-led surveys examining their sexual health practices in the context of their risk environments. Data were collected from April 2009-January 2010 from 54 venues. Multiple logistic regressions were conducted to assess socio-behavioral factors (e.g., age, education, length of time employed as an entertainer, and alcohol/drug use) and socio-structural factors (e.g., venue-level peer/manager support, condom rule/availability, and sex trafficking) associated with condom negotiation, adjusting for individuals nested within venues. Results Of 142 FSWs who traded sex in the previous 6 months (included in the analysis), 24% did not typically negotiate condom use with venue patrons. Factors in the physical environment - trafficked/coerced into work (AOR = 12.92, 95% CI = 3.34–49.90), economic environment - sex without a condom to make more money (AOR = 1.52, 95% CI 1.01–2.30), policy environment - sex without a condom because none was available (AOR = 2.58, 95% CI = 1.49–4.48), and individual risk - substance use (AOR = 2.36, 95% CI = 1.28–4.35) were independently associated with FSWs' lack of condom negotiation with venue patrons. Conclusions Factors in the physical, economic, and policy environments, over individual (excepting substance use) and social level factors, were significantly associated with these FSWs' condom negotiations in the Philippines. Drawing upon Rhodes' risk environment framework, these results highlight the need for policies that support safer sex negotiations among sex workers in the context of their risk environments.

    In October, 1993, 16 months after the United Nations approved the International Convention on Biodiversity held in Rio de Janeiro, June, 1992, the Philippine Congress ratified and adopted the Convention. This is a manifestation of the full support of the Philippines for the principles and policies adopted by the UN body on the conservation of biodiversity, sustainable development of biological resources and equitable sharing of benefits between users and owners of biodiversity resources. The Philippine scientific community has long recognized the need for and importance of a national guideline and policy with regard to the collection of plants and animals in the Philippines for scientific or commercial purposes. A series of consultative meetings were held by representatives of government agencies, non-government organizations, private organizations, academic and private persons concerned with biodiversity conservation to formulate national guidelines that regulate the collection of plant and animal specimens in the country. Guidelines were unanimously adopted by various government agencies and academia and a Memorandum of Agreement (MOA) was signed on September 28, 1990. Very recently a new document was drafted, specifically to serve as a guideline for those who desire to undertake sample collecting in the Philippines for biodiversity prospecting. The document is now being reviewed by government departments and agencies and will be presented to the President of the Philippines for signing as an Executive Order (EO). Once signed, this EO will serve as a national policy for bioprospecting in the country. The Philippines is one of the countries in Southeast Asia that has endorsed the adoption of regional guidelines on the collection of plant and animal organisms for drug development.

    Barrier, E.; Huchon, P.; Aurelio, M.

    1991-01-01

    On the basis of new geologic data and a kinematic analysis, we establish a simple kinematic model in which the motion between the Philippine Sea plate and Eurasia is distributed on two boundaries: the Philippine Trench and the Philippine fault. This model predicts a velocity of 2 to 2.5 cm/yr along the fault. Geologic data from the Visayas provide an age of 2 to 4 Ma for the fault, an age in good agreement with the date of the beginning of subduction in the Philippine Trench. The origin of the Philippine fault would thus be the flip of subduction from west to east after the locking of convergence to the west by the collision of the Philippine mobile belt with the Eurasian margin.

    In the Philippines, abortion is legally restricted. Nevertheless, many women obtain abortions--often in unsafe conditions--to avoid unplanned births. In 1994, the estimated abortion rate was 25 per 1,000 women per year; no further research on abortion incidence has been conducted in the Philippines. Data from 1,658 hospitals were used to estimate abortion incidence in 2000 and to assess trends between 1994 and 2000, nationally and by region. An indirect estimation methodology was used to calculate the total number of women hospitalized for complications of induced abortion in 2000 (averaged data for 1999-2001), the total number of women having abortions and the rate of induced abortion. In 2000, an estimated 78,900 women were hospitalized for postabortion care, 473,400 women had abortions and the abortion rate was 27 per 1,000 women aged 15-44 per year. The national abortion rate changed little between 1994 and 2000; however, large increases occurred in metropolitan Manila (from 41 to 52) and Visayas (from 11 to 17). The proportions of unplanned births and unintended pregnancies increased substantially in Manila, and the use of traditional contraceptive methods increased in Manila and Visayas. The increase in the level of induced abortion seen in some areas may reflect the difficulties women experience in obtaining modern contraceptives as a result of social and political constraints that affect health care provision. Policies and programs regarding both postabortion care and contraceptive services need improvement.

    Gelia Castillo, a specialist in rural sociology whose ideas have influenced policymakers in government, international development circles, and academe, pioneered the concept of participatory development. Born into a poor family, her father convinced her that academic achievement was the key to her future; her academic training includes a Bachelor of Arts in psychology from the University of the Philippines, a Master's in rural sociology from Pennsylvania State University, and a Doctorate from Cornell University. She served as professor of rural sociology at the College of Agriculture, University of the Philippines, and published extensively on women's roles, the sex roles of Filipino adolescents, agricultural school administration, the team approach in community development, rice and potato farming, the changing social images in a developing society, and the protein gap. "Beyond Manila," her most famous book, was the first comprehensive research work on income distribution, employment, labor, education, and migration in the rural Philippines. She underscored the definition of "household" and observed that the role of women and children contributes greatly to the dynamics of society. Her husband, Leopoldo Castillo, an animal nutritionist who is now professor emeritus at the Institute of Animal Science, has long supported his wife's career. The mother of two daughters and one son was the only female member of the board of the International Potato Center for 6 years and served on the boards of the IDRC, the International Service for National Agriculture Research, and the International Council for Research in Agroforestry. At 66, and retired, she believes affirmative action is necessary and that the feminist movement has only helped professional women.

    The western boundary of the Philippine Sea (PH) Plate in the Philippines and eastern Indonesia corresponds to a wide deformation zone that includes the stretched continental margin of Sundaland, the Philippine Mobile Belt (PMB), extending from Luzon to the Molucca Sea, and a mosaic of continental blocks around the PH/Australia/Sunda triple junction. The GPS GEODYSSEA data are used to decipher the present kinematics of this complex area. In the Philippines, the overall scheme is quite simple: two opposing rotations on either side of the left-lateral Philippine Fault, clockwise to the southwest and counterclockwise to the northeast, transfer 55 per cent of the PH/Sundaland convergence from the Manila Trench to the northwest to the Philippine Trench to the southeast. Further south, 80 per cent of the PH/Sunda convergence is absorbed in the double subduction system of the Molucca Sea and less than 20 per cent along both continental margins of northern Borneo. Finally, within the triple junction area between the Sundaland, PH and Australia plates, from Sulawesi to Irian Jaya, preferential subduction of the Celebes Sea induces clockwise rotation of the Sulu block, which is escaping toward the diminishing Celebes Sea oceanic space from the eastward-advancing PH Plate. To the south, we identify an undeformed Banda block that rotates counterclockwise with respect to Australia and clockwise with respect to Sundaland. The kinematics of this block can be defined and enable us to compute the rates of southward subduction of the Banda block within the Flores Trench and of eastward convergence of the Makassar Straits with the Banda block. The analysis made in this paper confirms that this deformation is compatible with the eastward motion of Sundaland with respect to Eurasia determined by the GEODYSSEA programme but is not compatible with the assumption that Sundaland belongs to Eurasia, as was often assumed prior to this study.

    NASA Image and Video Library

    1999-05-01

    This is an image of Taal volcano, near Manila on the island of Luzon in the Philippines. The black area in the center is Taal Lake, which nearly fills the 30-kilometer-diameter (18-mile) caldera. The caldera rim consists of deeply eroded hills and cliffs. The large island in Taal Lake, which itself contains a crater lake, is known as Volcano Island. The bright yellow patch on the southwest side of the island marks the site of an explosion crater that formed during a deadly eruption of Taal in 1965. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on its 78th orbit on October 5, 1994. The image shows an area approximately 56 kilometers by 112 kilometers (34 miles by 68 miles) that is centered at 14.0 degrees north latitude and 121.0 degrees east longitude. North is toward the upper right of the image. The colors in this image were obtained using the following radar channels: red represents the L-band (horizontally transmitted and received); green represents the L-band (horizontally transmitted and vertically received); blue represents the C-band (horizontally transmitted and vertically received). Since 1572, Taal has erupted at least 34 times. Since early 1991, the volcano has been restless, with swarms of earthquakes, new steaming areas, ground fracturing, and increases in water temperature of the lake. Volcanologists and other local authorities are carefully monitoring Taal to understand if the current activity may foretell an eruption. Taal is one of 15 "Decade Volcanoes" that have been identified by the volcanology community as presenting large potential hazards to population centers. The bright area in the upper right of the image is the densely populated city of Manila, only 50 kilometers (30 miles) north of the central crater. http://photojournal.jpl.nasa.gov/catalog/PIA01768

  20. Constructing vulnerability: the historical, natural and social generation of flooding in metropolitan Manila.

    PubMed

    Bankoff, Greg

    2003-09-01

    Flooding is not a recent hazard in the Philippines but one that has occurred throughout the recorded history of the archipelago. On the one hand, it is related to a wider global ecological crisis to do with climatic change and rising sea levels but on the other hand, it is also the effect of more localised human activities. A whole range of socio-economic factors such as land use practices, living standards and policy responses are increasingly influencing the frequency of natural hazards such as floods and the corresponding occurrence of disasters. In particular, the reason why flooding has come to pose such a pervasive risk to the residents of metropolitan Manila has its basis in a complex mix of inter-relating factors that emphasise how the nature of vulnerability is constructed through the lack of mutuality between environment and human activity over time. This paper examines three aspects of this flooding: first, the importance of an historical approach in understanding how hazards are generated; second, the degree of interplay between environment and society in creating risk; and third, the manner in which vulnerability is a complex construction.

    The author visited Bohol, a picturesque island in the Philippines 350 miles south of Manila, in 1986 and 1990 to observe and record the emerging deaf culture. Before the Peace Corps started a school program on the island some eight years ago, deaf children grew up functionally illiterate. Those who have not been found and are not enrolled in the fledgling school program still do, as they are completely isolated from the deaf community. This article describes heroic efforts to teach vocational skills to the deaf in Bohol. The project not only succeeded but led to the island's best restaurant, The Garden Cafe.

    Reconstructing the evolutionary history, demographic signal and dispersal processes from viral genome sequences contributes to our understanding of the epidemiological dynamics underlying epizootic events. In this study, a Bayesian phylogenetic framework was used to explore the phylodynamics and spatio-temporal dispersion of the O CATHAY topotype of foot-and-mouth disease virus (FMDV) that caused epidemics in the Philippines between 1994 and 2005. Sequences of the FMDV genome encoding the VP1 showed that the O CATHAY FMD epizootic in the Philippines resulted from a single introduction and was characterised by three main transmission hubs in Rizal, Bulacan and Manila Provinces. From a wider regional perspective, phylogenetic reconstruction of all available O CATHAY VP1 nucleotide sequences identified three distinct sub-lineages associated with country-based clusters originating in Hong Kong Special Administrative Region (SAR), the Philippines and Taiwan. The root of this phylogenetic tree was located in Hong Kong SAR, representing the most likely source for the introduction of this lineage into the Philippines and Taiwan. The reconstructed O CATHAY phylodynamics revealed three chronologically distinct evolutionary phases, culminating in a reduction in viral diversity over the final 10 years. The analysis suggests that viruses from the O CATHAY topotype have been continually maintained within swine industries close to Hong Kong SAR, following the extinction of virus lineages from the Philippines and the reduced number of FMD cases in Taiwan.

    High-resolution tomographic images are obtained by inverting a large number of arrival-time data of local earthquakes and teleseismic events to depict the 3-D crustal and upper mantle structure beneath the central Philippines. Our tomographic results show that the subducted South China Sea slab beneath the southern segment of the Manila Trench steepens and tears, resulting in migration of the locus of active volcanism in the Macolod Corridor, due to the collision between the Palawan microcontinental block and the Philippine Mobile Belt. The subduction of the Philippine Sea Plate along the Philippine Trench started at 10-12°N or south of 12°N, the central part of the trench, from at least ∼10 Ma estimated from our tomographic images. Our results reveal clearly a high-velocity anomaly in and around the mantle transition zone, which is interpreted as the subducted Proto South China Sea slab that sinks deeper southeastward, being well consistent with geological results that the age of collision between the Palawan microcontinental block and the Philippine Mobile Belt becomes younger from the south to the north. This collision zone can be divided into northern and southern segments, demarcated by the salient point of the collision zone, which is probably the boundary between the South China Sea slab and the Proto South China Sea slab, and may be ascribed to the complete consumption of the two slabs.

    The Philippine Mobile Belt, a seismically active, rapidly deforming plate boundary zone situated along the convergent Philippine Sea/Eurasian plate boundary, is examined using geodetic and seismological data. Oblique convergence between the Philippine Sea Plate and the Eurasian plate is accommodated by nearly orthogonal subduction along the Philippine Trench and the Manila Trench, as well as by strike-slip faulting along the Philippine Fault system. We develop a model of active plate boundary deformation in this region, using elastic block models constrained by known fault geometries, published GPS observations and focal mechanism solutions. We then present an estimate of block rotations, fault coupling, and intra-block deformation, based on the best-fit model that minimizes the misfit between observed and predicted geodetic vectors and earthquake slip vectors. Slip rates along the Philippine fault vary from ~22 - 36 mm/yr in the Central Visayas and about 10 to 40 mm/yr in Luzon, trending almost parallel to the fault trace. In northern Luzon, Philippine Fault splays accommodate transpressional strain. The Central Visayas block experiences convergence with the Sundaland block along the Negros Trench and the Mindoro-Palawan collision zone. On the eastern side of Central Visayas, sinistral strike-slip faulting occurs along the NNW-SSE-trending Philippine Fault. Mindanao Island in southern Philippines is dominated by east-verging subduction along the Cotabato Trench, and strain partitioning (strike- slip faulting with west-verging subduction) in eastern Mindanao along the southern Philippine Fault and Philippine Trench, respectively. Oblique active sinistral strike slip faults in Central and Eastern Mindanao that were hypothesized to be responsible for basin formation are obvious boundaries for tectonic blocks. Located south of Mindanao Island we define an adjoining oceanic block defined by the N-S trending complex dual subduction zone of Sangihe and Halmahera

    Ethnoastronomy refers to the system of beliefs and practices of ethno-linguistic groups regarding astronomical and meteorological phenomena which form part of the upper world in their three-world view of the universe. For the Philippines, the study is relevant in the investigation of Philippine pre-colonial society and culture. It is also important in showing the diversity, commonality, richness and depth of what would be referred to later on as Philippine cultures. Through this study, various Philippine groups which are usually neglected in the writing of history are brought to the forefront to share in the limelight with mainstream groups in tracing the development of this society and culture. The study focuses on the indigenous world view, beliefs, knowledge and practices regarding the sun, the moon, the eclipse and the stars. It shows how astronomical, as well as meteorological, phenomena influence the way people look at the world and the way they think, behave and live. Beliefs and knowledge regarding these phenomena inform their everyday life then and now as they continuously engage in agriculture, fishing, hunting, and trading, in observing various rituals, in building a house, and even in securing good fortune in any undertaking.

    An estimated 200,000-500,000 men, women, and children work in prostitution in the Philippines in a variety of venues, including brothels, nightclubs, pubs, massage parlors, and other legitimate entertainment establishments. Few, however, are voluntary prostitutes. Many people who work as prostitutes have been recruited from the provinces, kept in conditions similar to slavery, and forced to earn money from prostitution to pay for their transportation, board, and lodging. Many prostitutes work in urban centers and tourist resorts in the countryside. During the 1970s, then President Ferdinand Marcos promoted tourism as a major industry, effectively marketing attractive Filipinas to tourists. Sex tourism has flourished in the country ever since. Thousands of prostitutes are also located in Olongapo and Angeles, 2 cities north of Manila, from where they serve the sexual desires of US military personnel. The presence of US military personnel in the Philippines has always been associated with prostitution. The country's social hygiene centers, prostitutes in Manila and Davao, and AIDS education are briefly discussed.

    The Manila subduction zone is located at the convergent boundary between the Philippine Sea Plate and the Sunda/Eurasian Plate from offshore Taiwan to northern Luzon of Philippines, where only infrequent M7 earthquakes were observed in modern seismological instrumentation history. The lack of great events (M8+) indicates the subduction fault is either aseismically slipping or is accumulating strain energy toward rapid release in a great earthquake. Here we conduct numerical simulations of earthquake rupture sequences in the framework of rate-state-friction along the 15-19.5ºN segment of the 3D plate boundary with subducted seamounts. Rate-state frictional properties are constrained by laboratory friction experiments conducted on IODP Expedition 349, South China Sea (SCS), drilling samples from the basaltic basement rock under 100ºC - 600ºC, effective normal stress of 50 MPa and pore pressure of 100 MPa. During the modeled 2000-year period, the maximum magnitude of earthquakes is Mw7. Each sequence repeats every ~200 years and is consisted of three sub-events, event 1 (Mw7) that can overcome the barrier, where dip angle changes most rapidly along the strike, to rupture the entire fault. Events 2 (Mw 6.4) and 3 (Mw 5.7) are of smaller magnitudes and result in north-south segmented rupture pattern. We further quantify the potential of earthquake nucleation by the S-ratio (lower S ratio means the initial stress is closer to peak strength, hence more likely to nucleate an earthquake). The subducted seamount shows higher S-ratios than its surroundings mostly, implying an unlikely nucleate area. Our results are qualitatively similar to 2D subduction earthquake modeling by Herrendörfer et al. (2015, 2-3 events per supercycle and median long-term S is 0.5-1). Finally, we plan to use our coseismic rupture model results as inputs for a tsunami propagation model in SCS. Compared to the kinematic seafloor deformation input, our physics-based earthquake source model and its

    Expanding the power generation and distribution capability of the Philippines remains a top priority of the Philippine government. It is therefore not surprising that a number of the most significant legislative initiatives approved by the Philippine legislature in the past few years have been designed to encourage these activities in particular. There are several recent, significant statutes that will affect both power and non-power projects undertaken in the Philippines.

    Flood management decision-making is often supported by risk assessment, which may overlook the role of coping capacity and the potential benefits derived from direct use of flood-prone land. Alternatively, risk-benefit analysis can support floodplain management to yield maximum socio-ecological benefits for the minimum flood risk. We evaluate flood risk-probabilistic benefit tradeoffs of livelihood practices compatible with direct human use of flood-prone land (agriculture/wild fisheries) and nature conservation (wild fisheries only) in Candaba, Philippines. Located north-west to Metro Manila, Candaba area is a multi-functional landscape that provides a temporally-variable mix of possible land uses, benefits and ecosystem services of local and regional value. To characterize inundation from 1.3- to 100-year recurrence intervals we couple frequency analysis with rainfall-runoff-inundation modelling and remotely-sensed data. By combining simulated probabilistic floods with both damage and benefit functions (e.g. fish capture and rice yield with flood intensity) we estimate potential damages and benefits over varying probabilistic flood hazards. We find that although direct human uses of flood-prone land are associated with damages, for all the investigated magnitudes of flood events with different frequencies, the probabilistic benefits ( 91 million) exceed risks by a large margin ( 33 million). Even considering risk, probabilistic livelihood benefits of direct human uses far exceed benefits provided by scenarios that exclude direct "risky" human uses (difference of 85 million). In addition, we find that individual coping strategies, such as adapting crop planting periods to the flood pulse or fishing rather than cultivating rice in the wet season, minimize flood losses ( 6 million) while allowing for valuable livelihood benefits ($ 125 million) in flood-prone land. Analysis of societal benefits and local capacities to cope with regular floods demonstrate the

  14. The Philippines: integrated planning for balanced urban growth.

    PubMed

    1981-12-01

    During the past 80 years, the proportion of the Philippine population living in urban areas has nearly tripled, from 13% at the beginning of the 20th century to 36% in 1980. The number of people living in urban areas multipled 17-fold over this period. Currently, an estimated 17 million people live in urban areas, and this number is expected to reach 30 million by the year 2000. Migration from rural areas has been an important component of urban growth, but it has not been the principal one. Natural increase accounted for 54% of total urban growth in the 1960s and 1970s. A combination of reclassification and migration accounted for the rest. Big cities did not grow as rapidly as small cities, since their growth was generated largely by urban inmigration. Small cities tended to grow faster due to more natural increase than to inmigration. Philippine urbanization has been marked by increasing primacy. Metropolitan Manila, the largest city, has more than quadrupled in size since 1950. The phenomenon of primacy has been the cumulative consequence of historical, demographic, political, and socioeconomic factors. It may also have resulted from growth policies which unintentionally and indirectly favored the premier city. For national planners, the issue of urbanization in the Philippines is closely intertwined with the country's development objectives, particularly those of reducing poverty and attaining a more equitable distribution of income and wealth. The integration of population growth and distribution trends into the planning process is very important. Efforts to actively advocate this approach at various planning levels have been initiated. More must be learned about population and development dynamics, and planning capabilities at all levels must be improved.

    The complex tectonics surrounding the Philippine Islands are dominated by the interactions of the Pacific, Sunda, and Eurasia plates with the Philippine Sea plate (PSP). The latter is unique because it is almost exclusively surrounded by zones of plate convergence. At its eastern and southeastern edges, the Pacific plate is subducted beneath the PSP at the Izu-Bonin, Mariana, and Yap trenches. Here, the subduction zone exhibits high rates of seismic activity to depths of over 600 km, though no great earthquakes (M>8.0) have been observed, likely because of weak coupling along the plate interface. In the northeast, the PSP subducts beneath Japan and the eastern margin of the Eurasia plate at the Nankai and Ryukyu trenches, extending westward to Taiwan. The Nankai portion of this subduction zone has hosted some of the largest earthquakes along the margins of the PSP, including a pair of Mw8.1 megathrust events in 1944 and 1946. Along its western margin, the convergence of the PSP and the Sunda plate is responsible for a broad and active plate boundary system extending along both sides of the Philippine Islands chain. The region is characterized by opposite-facing subduction systems on the east and west sides of the islands, and the archipelago is cut by a major transform structure: the Philippine Fault. Subduction of the Philippine Sea plate occurs at the eastern margin of the islands along the Philippine Trench and its northern extension, the East Luzon Trough. On the west side of Luzon, the Sunda Plate subducts eastward along a series of trenches, including the Manila Trench in the north, the smaller Negros Trench in the central Philippines, and the Sulu and Cotabato trenches in the south. Twentieth and early twentyfirst century seismic activity along the boundaries of the Philippine Sea plate has produced seven great (M>8.0) earthquakes and 250 large (M>7) events. Among the most destructive events were the 1923 Kanto, the 1948 Fukui, and the 1995 Kobe, Japan

    reconstruction the Central Luzon basin and Luzon volcanic arc are continuous with the forearc basin and volcanic belt on Panay, as a continuous arc and forearc extending from northern Ilocos to southern Panay. After collision with the Palawan-Mindoro continental block, continued motion along the Manila trench north of Mindoro has ruptured the central Philippines along the Sibuyan Sea branch of the Philippine fault. Thus the Sibuyan Sea branch could account for most of the post-early to middle Miocene relative motion between Luzon and the Visayas.

    Background: Childhood cancer survival estimates from developing nations are rare. Methods: Using the US SEER and the Manila and Rizal Cancer Registry databases in the Philippines, 5-year survival for childhood leukaemia and lymphoma in 2001–2005 among Asian Americans were compared with both Filipinos and Caucasians in the United States. Estimates for patients in the United States in earlier time periods were compared with that of Philippine residents to estimate delay in achievements of comparable levels of survival. Results: Childhood leukaemia and lymphoma relative survival was much lower in Filipinos living in the Philippines (32.9 and 47.7%) than in Asian Americans (80.1 and 90.5%) and Caucasians (81.9 and 87%). Achievement of comparable survival rates of Philippine residents lagged behind by 20 to >30 years compared with patients in the United States. Conclusions: The large differences in survival estimates of US populations and Philippine residents highlight the deficiencies of paediatric cancer care delivery in the Philippines. The long survival lag underlines the need for major improvements in access to diagnostic and treatment facilities. PMID:20485290

    The major French site of Manila clam Ruditapes philippinarum (Adams and Reeves, 1850) cultivation is located in the Chausey Archipelago where the associated practices are highly mechanized: every steps of production are made with tractor-driven machinery. The Manila clam concessions are concentrated on Lanice conchilega (Pallas, 1766) bioherms, which are known to increase alpha-diversity and to locally modify sediment dynamics. This study focus on the impacts of Manila clam cultivation on (i) the natural populations of L. conchilega and on (ii) the structure of the associated benthic assemblages during the different steps of the farming production cycle. We found that the L. conchilega populations are significantly affected within the concessions where their total abundances drastically decrease, their spatial patterns are modified and the associated benthic assemblages are significantly altered. Our results are discussed in a context of a sustainable management of the Manila clam cultivation in coastal areas.

    A ground based sky imaging system was developed at the Manila Observatory in 2012 to measure cloud occurrence and to analyse seasonal variation of cloud cover over Metro Manila. Ground-based cloud occurrence measurements provide more reliable results compared to satellite observations. Also, cloud occurrence data aid in the analysis of radiation budget in the atmosphere. In this study, a GoPro Hero 2 with almost 180o field of view is employed to take pictures of the atmosphere. These pictures are taken continuously, having a temporal resolution of 1min. Atmospheric images from April 2012 to June 2013 (excluding the months of September, October, and November 2012) were processed to determine cloud cover. Cloud cover in an image is measured as the ratio of the number of pixels with clouds present in them to the total number of pixels. The cloud cover values were then averaged over each month to know its monthly and seasonal variation. In Metro Manila, the dry season occurs in the months of November to May of the next year, while the wet season occurs in the months of June to October of the same year. Fig 1 shows the measured monthly variation of cloud cover. No data was collected during the months of September (wherein the camera was used for the 7SEAS field campaign), October, and November 2012 (due to maintenance and repairs). Results show that there is high cloud cover during the wet season months (80% on average) while there is low cloud cover during the dry season months (62% on average). The lowest average cloud cover for a wet season month occurred in June 2012 (73%) while the highest average cloud cover for a wet season month occurred in June 2013 (86%). The variations in cloud cover average in this season is relatively smaller compared to that of the dry season wherein the lowest average cloud cover in a month was during April 2012 (38%) while the highest average cloud cover in a month was during January 2013 (77%); minimum and maximum averages being 39

    In the selection of sites for disposal facilities involving low- and intermediate-level radioactive waste (LILW), International Atomic Energy Agency (IAEA) recommendations require that 'the region in which the site is located shall be such that significant tectonic and surface processes are not expected to occur with an intensity that would compromise the required isolation capability of the repository'. Evaluating the appropriateness of a site therefore requires a deep understanding of the geological and tectonic setting of the area. The Philippines sits in a tectonically active region frequented by earthquakes and volcanic activity. Its highly variable morphology coupled with its location along the typhoon corridor in the west Pacific region subjects the country to surface processes often manifested in the form of landslides. The Philippine LILW near surface repository project site is located on the north eastern sector of the Island of Luzon in northern Philippines. This island is surrounded by active subduction trenches; to the east by the East Luzon Trough and to the west by the Manila Trench. The island is also traversed by several branches of the Philippine Fault System. The Philippine LILW repository project is located more than 100 km away from any of these major active fault systems. In the near field, the project site is located less than 10 km from a minor fault (Dummon River Fault) and more than 40 km away from a volcanic edifice (Mt. Caguas). This paper presents an analysis of the potential hazards that these active tectonic features may pose to the project site. The assessment of such geologic hazards is imperative in the characterization of the site and a crucial input in the design and safety assessment of the repository. (authors)

    The frequent incidents caused by metro passengers in China suggest that it is necessary to explore the classification and effects of passenger behaviors and their relations to incident involvement. A metro passenger behavior questionnaire (MPBQ) and a metro station staff questionnaire (MSSQ), both comprising 32 behavior items, were developed and surveyed on a sample of metro passengers (N=579) and metro staff (N=99). Using the MPBQ, the self-reported frequency of each aberrant behavior was measured and subjected to explanatory factor analysis, which revealed a three-factor solution on the 28 retained behavior items: transgressions, self-willed inattentions and abrupt violations. ANOVA was used to examine the effects of demographic and riding profile variables on different types of behaviors. The MSSQ was used to collect metro staff opinions on behavior frequency, severity and entities that might be affected, given that a specific behavior occurred. An importance hierarchy was established over the 32 identified behaviors to determine the most important riding behaviors. Finally, logistic regression showed that riding time, number of stops experienced by a passenger and, more importantly, transgressions and abrupt violations, were significant predictors of incident involvement. The possible explanations and implications of the findings might help in understanding passenger behaviors and targeting metro safety interventions in ways that promote safer operations.

    Evidence-based practice (EBP) is integral in the health care system whether in developed or developing countries. Thus, all health professionals need to be trained in EBP. An EBP training program was conducted to health professionals in a developing country, the Philippines. The health professionals (medical doctors and allied health professionals [physical therapists and occupational therapists]) were working in hospitals in Manila, Philippines. The program aimed to build capacity in EBP in terms of knowledge and skills. The EBP training program was conducted as a 1-day face-to-face training. Pre- and post-test measures of EBP knowledge and skills were taken prior to and immediately after the 1-day training, using the Fresno test of evidence-based medicine for the medical doctors and the Adapted Fresno test for the allied health professionals. The EBP training program resulted in significant improvements in knowledge and skills for both the medical doctors (change in pre- and post-Fresno test measures, 95% confidence interval [CI]: 14.6-23.5; P≤0.05) and the allied health professionals (change in pre- and post-Adapted Fresno test measures, 95% CI: 32.7-38.5; P≤0.05). The EBP training conducted amongst the health professionals is an effective and tested undertaking in introducing EBP in developing countries such as the Philippines.

    The magnitudes and epicenters of Philippine earthquakes from 1589 to 1895 are estimated based on the review, evaluation and interpretation of historical accounts and descriptions. The first step involves the determination of magnitude-felt area relations for the Philippines for use in the magnitude estimation. Data used were the earthquake reports of 86, recent, shallow events with well-described effects and known magnitude values. Intensities are assigned according to the modified Mercalli intensity scale of I to XII. The areas enclosed by Intensities III to IX [ A(III) to A(IX)] are measured and related to magnitude values. The most robust relations are found for magnitudes relating to A(VI), A(VII), A(VIII) and A(IX). Historical earthquake data are obtained from primary sources in libraries in the Philippines and Spain. Most of these accounts were made by Spanish priests and officials stationed in the Philippines during the 15th to 19th centuries. More than 3000 events are catalogued, interpreted and their intensities determined by considering the possible effects of local site conditions, type of construction and the number and locations of existing towns to assess completeness of reporting. Of these events, 485 earthquakes with the largest number of accounts or with at least a minimum report of damage are selected. The historical epicenters are estimated based on the resulting generalized isoseismal maps augmented by information on recent seismicity and location of known tectonic structures. Their magnitudes are estimated by using the previously determined magnitude-felt area equations for recent events. Although historical epicenters are mostly found to lie on known tectonic structures, a few, however, are found to lie along structures that show not much activity during the instrumented period. A comparison of the magnitude distributions of historical and recent events showed that only the period 1850 to 1900 may be considered well-reported in terms of

    This is an image of Taal volcano, near Manila on the island of Luzon in the Philippines. The black area in the center is Taal Lake, which nearly fills the 30-kilometer-diameter (18-mile) caldera. The caldera rim consists of deeply eroded hills and cliffs. The large island in Taal Lake, which itself contains a crater lake, is known as Volcano Island. The bright yellow patch on the southwest side of the island marks the site of an explosion crater that formed during a deadly eruption of Taal in 1965. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on its 78th orbit on October 5, 1994. The image shows an area approximately 56 kilometers by 112 kilometers (34 miles by 68 miles) that is centered at 14.0 degrees north latitude and 121.0 degrees east longitude. North is toward the upper right of the image. The colors in this image were obtained using the following radar channels: red represents the L-band (horizontally transmitted and received); green represents the L-band (horizontally transmitted and vertically received); blue represents the C-band (horizontally transmitted and vertically received). Since 1572, Taal has erupted at least 34 times. Since early 1991, the volcano has been restless, with swarms of earthquakes, new steaming areas, ground fracturing, and increases in water temperature of the lake. Volcanologists and other local authorities are carefully monitoring Taal to understand if the current activity may foretell an eruption. Taal is one of 15 'Decade Volcanoes' that have been identified by the volcanology community as presenting large potential hazards to population centers. The bright area in the upper right of the image is the densely populated city of Manila, only 50 kilometers (30 miles) north of the central crater.

    Introduction: Typhoon Yolanda (Haiyan) hit the central part of the Philippines on November 8, 2013. To identify possible outbreaks of communicable diseases after the typhoon, nasopharyngeal swabs, stool and blood samples were collected from patients who visited the Eastern Visayas Regional Medical Center due to acute respiratory infection (ARI), acute gastroenteritis (AGE) or other febrile illness (OFI) including suspected dengue fever, between November 28, 2013 and February 5, 2014.   Methods: Samples were tested on-site for selected pathogens using rapid diagnostic tests. Confirmation and further analysis were conducted at the Research Institute for Tropical Medicine (RITM) in Manila using polymerase chain reaction (PCR) and sequencing. Residues of the rapid diagnostic tests and samples collected in the filter papers (FTATM card) were transported to Manila under suboptimal conditions. PCR results were compared between the kit residues and the filter papers.   Results: A total of 185 samples were collected. Of these, 128 cases were ARI, 17 cases were AGE and 40 cases were OFI. For nasopharyngeal swab samples, detection rates for enterovirus and rhinovirus residues were higher than the filter papers. For stool samples, rotavirus positive rate for the filter paper was higher than the kit residues. We also managed to obtain the sequence data from some of the kit residues and filter papers.   Discussion: Our results confirmed the importance of PCR for the laboratory diagnosis of infectious diseases in post-disaster situations when  diagnostic options are limited.

    Marine invertebrate microbiota has a key function in host physiology and health. To date, knowledge about bivalve microbiota is poorly documented except public health concerns. This study used a molecular approach to characterize the microbiota associated with the bivalve Manila clam (Ruditapes philippinarum) by determining (1) the difference among organs either or not under the influence of host habitat, (2) small-scale variability of microbiota, and (3) the experimental response of the Manila clam microbiota submitted to different lateral transmissions. These questions were investigated by sampling two groups of individuals living in contrasting habitats and carrying out a transplant experiment. Manila clam microbiota (i.e., bacterial community structure) was determined at organ-scale (gills, gut, and a pool of remaining tissues) by capillary electrophoresis DNA fingerprinting (CE fingerprinting). The Manila clam microbiota structure differed among organs indicating a selection of Manila clam microbiota at organ scale. Habitat strongly influenced gill and gut microbiota. In contrast, microbiota associated with remaining tissues was similar between group individuals suggesting that these communities are mostly autochthonous, i.e., Manila clam specific. Transplant experiment showed that improving living condition did not induce any change in microbiota associated with remaining tissues. In contrast, the reduction in individual habitat quality led to individuals in declining health as strongly suggested by the increase in phagocytosis activity and decrease in condition index together with the change in internal organ microbiota. This study provides a first description of the Manila clam holobiont which can withstand disturbance and respond opportunistically to improved environmental conditions.

  14. Inter-country and ethnic variation in colorectal cancer survival: Comparisons between a Philippine population, Filipino-Americans and Caucasians

    PubMed Central

    2010-01-01

    Background Previous population-based studies showed differences in international and within country colorectal cancer survival estimates, but few investigated the role of prognostic factors. Using a "high resolution approach", we aimed to determine the effect of ethnicity and health care by comparing Filipino-Americans with Philippine residents, who have the same ethnicity, and with Caucasians living in the US, who have the same health care system. Methods Using databases from the Manila and Rizal Cancer Registries and the United States Surveillance, Epidemiology and End Results, age-adjusted five-year absolute and relative survival estimates were computed and compared between Filipino-American colorectal cancer patients, cancer patients from the Philippines and Caucasian patients. Cox proportional hazards modelling was used to determine factors affecting survival differences. Results Much lower 5-year relative survival estimates were obtained for Philippine residents (37%) as compared to those in Filipino-Americans (60.3%) and Caucasians (62.4%). Differences in age, stage and receipt of surgery explained a large proportion of the survival differences between Philippine residents and Filipino-Americans. However, strong excess risk of death for Philippine residents remained after controlling for these and other variables (relative risk, RR, 2.03, 95% confidence interval, 95% CI, 1.83-2.25). Conclusions Strong survival disadvantages of Philippine residents compared to Filipino-American patients were disclosed, which most likely reflect differences in access to and utilization of health care. Health education and advocacy, for both patients and health practitioners, should likewise be given priority. PMID:20233442

    The Manila clam Venerupis philippinarum is a good biomonitor/bioindicator to marine metal pollution and is frequently used in aquatic toxicology. Two dominant pedigrees (white and zebra) of clam are distributed in the Bohai Sea; however, little attention has been paid to potential biological differences between these two pedigrees. In this study, we tested the sensitivity of both pedigrees to marine metal (cadmium and zinc) pollution biomonitoring and marine environmental toxicology. Results demonstrate significant biological differences in gills of white and zebra clams based on metabolic profiles and antioxidant enzyme activities. In addition, we found that hypotaurine, malonate and homarine were relatively high in white clam gills, while alanine, arginine, glutamate, succinate, 4-aminobutyrate, taurine and betaine were high in zebra clam gills. Zebra clam gills were also more sensitive to a mixture of Cd and Zn, as shown by antioxidant enzyme activities and metabolic profiles, but white clam gills could accumulate more Zn. Therefore, we suggest that the white pedigree can be used as a biomonitor to marine Zn pollution, whereas the zebra pedigree can be used for toxicology studies on Cd and Zn mixed pollution.

    The physiological responses of marine bivalves to chronic cadmium (Cd) exposure at sub-lethal concentrations have been well documented. As of now, few studies have examined the effect of Cd exposure and subsequent recovery period at environmentally realistic concentrations. In this study, environmentally, Cd exposures were performed to assess the physiological responses of the Manila clam Ruditapes philippinarum. The clams were exposed to waterborne Cd at two environmentally realistic concentrations (4 and 40 μg L(-1)) for 35 days and then allowed to recover for another 35 days. The accumulation and elimination of Cd in R. philippinarum were tissue-specific and dose- and time-dependent. Cd accumulation increased sharply in the digestive gland, and Cd elimination was rapid in the gill. Major physiological responses, including clearance rate, absorption efficiency, respiration rate, excretion rate, oxygen to nitrogen ratio, and scope for growth, were significantly affected by Cd exposure. Yet, the clams exposed to 4-μg L(-1) Cd were able to quickly recover their normal physiological processes and clearly exhibited catch-up growth once they were transferred to clean seawater. Hence, R. philippinarum can exhibit good physiological plasticity when confronted with moderately environmental Cd exposure. All physiological responses measured exhibited a highly significant and generally predictable correlation with tissue Cd concentration, which in turn, reflected environmentally realistic exposure conditions. Our results further confirm that the measurement of physiological responses is a sensitive method for assessing stress at environmentally realistic metal concentrations.

    Despite the availability of population-based cancer survival data from the developed and developing countries, comparisons remain very few. Such comparisons are important to assess the magnitude of survival discrepancies and to disentangle the impact of ethnic background and health care access on cancer survival. Using the SEER 13 database and databases from the Manila and Rizal Cancer Registries in the Philippines, a 5-year relative survival for 9 common cancers in 1998–2002 of Filipino-American cancer patients were compared with both cancer patients from the Philippines, having the same ethnicity, and Caucasians in the United States, being exposed to a similar societal environment and the same health care system. Survival estimates were much higher for the Filipino-Americans than the Philippine resident population, with particularly large differences (more than 20–30% units) for cancers with good prognosis if diagnosed and treated early (colorectal, breast and cervix), or those with expensive treatment regimens (leukaemias). Filipino-Americans and Caucasians showed very similar survival for all cancer sites except stomach cancer (30.7 vs 23.2%) and leukaemias (37.8 vs 48.4%). The very large differences in the survival estimates of Filipino-Americans and the Philippine resident population highlight the importance of the access to and utilisation of diagnostic and therapeutic facilities in developing countries. Survival differences in stomach cancer and leukaemia between Filipino-Americans and Caucasians in the United States most likely reflect biological factors rather than the differences in access to health care.

    The authors describe the first parasitological survey of protozoal infections on tissue slide sections of field cases processed at the histopathology laboratory of the College of Veterinary Medicine (CVM) at the University of the Philippines Los Baños (UPLB). Over 80% of the field cases were from Region 4 (CALABARZON) and the rest were equally distributed from other areas of the Philippines, namely: Region 2 (Cagayan Valley), Metropolitan Manila (National Capital Region), Region III (Central Luzon) and Region VI (Western Visayas). Histopathological analyses of tissue sections from 51 archived cases (1972-2010) of parasitic aetiology were performed. Microscopic examination of a total of 286 histopathological slides revealed the presence of several protozoa, including sarcosporidiosis, hepatic coccidiosis, intestinal coccidiosis, balantidiosis and leucocyto-zoonosis. In addition, the finding of Balantidium and Sarcocystis may have zoonotic implications and can therefore be used as markers of public health importance.

    To identify the metacercariae of a gymnophallid trematode in the Manila clam Ruditapes philippinarum from the Ariake Sea, experimental infection and molecular analysis were conducted. Based on the morphology of adult worms obtained from experimentally infected mice, the parasite was identified as Parvatrema duboisi. Comparison of internal transcribed spacer (ITS) region of ribosomal DNA (rDNA) sequences for metacercariae and sporocysts from Manila clams and adult worms collected from wild wigeon Anas penelope showed minor differences ranging from 0 to 0.8%. These data strongly suggest that in the Ariake Sea, the parasite has a lifecycle using the Manila clam as the first and second intermediate hosts and wigeon as the definitive host.

    Akkeshi Lake is a subarctic shallow brackish lagoon located in Hokkaido, Japan. The Manila clam, Ruditapes philippinarum, is cultured in sandy sediments at the shallow, intertidal flat near the mouth of the lake. To quantitatively evaluate the effects of environmental factors such as water temperature and food availability on the growth of the Manila clam and to estimate the responses of Manila clam growth and food availability to global warming in Akkeshi Lake, we developed a numerical model by coupling a three-dimensional ecosystem model with a bioenergetics model for the growth of the Manila clam. We ran the model under two different conditions: the present condition and the global warming condition. For the global warming condition, water temperature was increased by 2 °C at the open boundary for the entire computational period. The growth of the Manila clam was limited by water temperature and food availability. The Manila clam grew up to 1.33 g dry weight ind.-1 at the lake mouth (station A) for 5 years, whereas it grew up to 1.00 g dry weight ind.-1 at the lake center (station B). The difference in the biomass of the Manila clam between two stations was due to the difference in food availability. Under the global warming condition, the water temperature limitation for the Manila clam was relaxed with a water temperature increase. The Manila clam grew up to 1.55 g dry weight ind.-1 at station A and 1.10 g dry weight ind.-1 at station B. While the growth of the Manila clam was improved in the lake under the global warming condition, its food sources, especially phytoplankton, decreased because of ingestion increases of grazers.

    Thousands of street children of Manila are affected by early-in-life oral infection. The aim of the present investigation was to evaluate the effectiveness of a sea-salt mouthrinse solution in street children of Manila affected by mild to severe forms of periodontal disease. These children were all in need of special protection: abandoned, abused, exploited, neglected, orphaned, poor. During 3 oral-health missions in 2003, 2004 and 2005, 617 abandoned children (5 to 13 year-old), received oral examination at a non-sectarian child-caring institution in Metro Manila (Virlanie Foundation) by calibrated examiners. A treatment based on what could be done was proposed: 1. Teaching of a precise tooth brushing technique with sea-salt, controlled and reinforced every two days for one week by calibrated health educators, 2. The application of sea-salt water mouthrinse (2.5 gram in 20 ml). Periodontal measurements were repeated at the end of each mission. All children returned to child-caring institution for the followup examinations. In 2003, 10 male and 11 female (n=21) were diagnosed with aggressive periodontitis. In 2009 and 2010, none was affected by aggressive periodontitis. For all patients, the gingival index decreased from 1.08 at the first mission to 1.04 at the end of the second mission and 0.98 at the end of the third mission. The periodontal index decreased from 1.33 at the first mission to 0.98 at the second mission and 0.92 at the last mission. The present investigation confirms that prevention and early diagnosis can result in success with minimum cost. The provided oral health program empowered street children in the most desperate circumstances to be educated and become self-reliant, independent, and responsible. We propose here an antimicrobial approach which has a high degree of efficacy and tolerability, and can be implemented in virtually all parts of the world using low-cost resources.

    This report presents a description of the trends in growth of the elderly population in the Philippines and their health, disability, education, work status, income, and family support. The proportion of elderly in the Philippines is much smaller than in other Southeast Asian countries, such as Singapore and Malaysia. The elderly population aged over 65 years increased from 2.7% of total population in 1990 to 3.6% in 1990. The elderly are expected to comprise 7.7% of total population in 2025. The proportion of elderly is small due to the high fertility rate. Life expectancy averages 63.5 years. The aged dependency ratio will double from 5.5 elderly per 100 persons aged 15-64 years in 1990 to 10.5/100 in 2025. A 1984 ASEAN survey found that only 11% of elderly rated their health as bad. The 1990 Census reveals that 3.9% were disabled elderly. Most were deaf, blind, or orthopedically impaired. 16% of elderly in the ASEAN survey reported not seeing a doctor even when they needed to. 54% reported that a doctor was not visited due to the great expense. In 1980, 67% of men and 76% of women aged over 60 years had less than a primary education. The proportion with a secondary education in 2020 is expected to be about 33% for men and 33% for women. 66.5% of men and 28.5% of women aged over 60 years were in the formal labor force in 1990. Women were less likely to receive cash income from current jobs or pensions. 65% of earnings from older rural people was income from agricultural production. 60% of income among urban elderly was from children, and 23% was from pensions. Family support is provided to the elderly in the form of coresidence. In 1988, 68% of elderly aged over 60 years lived with at least one child. Retirement or nursing homes are uncommon. The Philippines Constitution states that families have a duty to care for elderly members.

  3. Malnutrition in the Philippines.

    In the Philippines poverty and pervasive malnutrition are not limited to families of deprived seasonal workers. Undernourishment is endemic and increasing throughout most of this archipelago of some 7100 islands, and is compounded by the prevalence of intestinal parasites and gastrointestinal diseases which health workers estimate deprive youngsters of at least 5-10% of the nutritional value in food they do consume. This problem is particularly prevalent in rural villages and city slums where many people eat with their fingers. According to the Philippine Ministry of Health, nearly 1/2 of all reported deaths are among infants and children through age 4, and about 1/2 of the accelerated death rate among those age 5 and younger is related to malnutrition, compounded by diarrhea, measles, and malaria which is returning to areas where it once was almost eradicated. 3 factors critically affect a newborn's survival prospects: the family size he or she is born into; the time or spacing between the mother's pregnancies; and the child's birth order. Evidence indicates that, during the 1970s, as US aid and other family planning assistance became available, they were used most among families in the 2 highest income classes, where reduction of family size is under way. Poverty is the most fundamental cause of malnutrition, although many other factors contribute. Land reform has brought security of tenure and increasingly is transferring ownership of fields to former tenants of rice and corn lands. For the former tenants enhanced security brings greater income and better eating for the farm families retain more of the crop. The undernourished and truly poor of the Philippines number about 1/2 of the population. Although dispersed throughout most of the archipelago, there are important regional differences. These related to marked geographic patterns that affect fertility of the soil, length of the dry season, fortunes of predominant crops, vulnerability to destructive typhoons

    Water samples from Vietnam, The Philippines, and Myanmar were analyzed for artificial sweeteners (ASs) and iodinated X-ray contrast media (ICMs). High concentrations (low micrograms per liter) of ASs, including aspartame, saccharin, and sucralose, were found in wastewater treatment plant (WWTP) influents from Vietnam. Three ICMs, iohexol, iopamidol, and iopromide were detected in Vietnamese WWTP influents and effluents, suggesting that these ICMs are frequently used in Vietnam. ASs and ICMs were found in river water from downtown Hanoi at concentrations comparable to or lower than the concentrations in WWTP influents. The ASs and ICMs concentrations in WWTP influents and adjacent surface water significantly correlated (r (2) = 0.99, p < 0.001), suggesting that household wastewater is discharged directly into rivers in Vietnam. Acesulfame was frequently detected in northern Vietnamese groundwater, but the concentrations varied spatially by one order of magnitude even though the sampling points were very close together. This implies that poorly performing domestic septic tanks sporadically leak household wastewater into groundwater. High acesulfame, cyclamate, saccharin, and sucralose concentrations were found in surface water from Manila, The Philippines. The sucralose concentrations were one order of magnitude higher in the Manila samples than in the Vietnamese samples, indicating that more sucralose is used in The Philippines than in Vietnam. Acesulfame and cyclamate were found in surface water from Pathein (rural) and Yangon (urban) in Myanmar, but no ICMs were found in the samples. The ASs concentrations were two-three orders of magnitude lower in the samples from Myanmar than in the samples from Vietnam and The Philippines, suggesting that different amounts of ASs are used in these countries. We believe this is the first report of persistent ASs and ICMs having ubiquitous distributions in economically emerging South Asian countries.

    This paper presents the spatial variations in the crustal stress field for the Philippine region. Based on the stress configuration, we divided the stress regime in the area of the Philippines into four parts: (1) Trench-perpendicular compressive stress axes (σ1) with an intermediate plunge were observed along the eastern subduction systems of the Philippine Mobile Belt (PMB), which suggests that the subduction of the Philippine Sea Plate (PSP) is the primary factor controlling the stress distribution. (2) Characterized by systematically rotated σ1 with very shallow plunge, the central-western portion of the Philippines appears to be largely affected by the collision between the Palawan Block and the PMB. (3) The σ1 distribution in the northern part of Luzon Island (north of 14°N) is compatible with the plate motion of the PSP, whereas the extensional axes (σ3) has a fan-shaped stress signature with N-S direction at the south and a more spreading direction to the north, which implies its north escapement. (4) Bounded by the Scarborough Seamount, the northern and southern portions of the Manila Trench reveal a very distinct stress pattern with a trench-parallel σ3 to the north and a trench-perpendicular σ3 to the south. This observation may infer a potential effect caused by the presence of the oceanic bathymetric highs on the behavior of the subduction process. In addition to the identification of the four provinces with different stress regimes, we suggest that the Philippine Fault Zone may play an important role to alter the stress state in the region of the Philippines.

    The Philippines is to spend $5.4 billion over the next ten years for the development of alternative sources of energy. These would include the development of fuel woods and other biomass, and the commercialization of a coconut/diesel-oil fuel. It is hoped that the Philippines' dependence on imported oil will be reduced from about 80% today to around 50% by the end of the decade.

    The Asian Regional Conference on Gender and Communication, held in the Philippines, developed a plan of action to improve the portrayal of women in the mass media. Even in developing countries with traditional attitudes toward women, pornographic-type images are used to boost product sales. The conference's recommendations address the challenges posed by globalization of the media, commercialization of local media, and the increased violation of women's human rights in the media and the question of who has control over the media. After the conference, ISIS Maila assembled a report, "Status of Women and Media: Focus on Violence Against Women," which will be presented at a forum held during the 1998 meeting of the United Nations Commission on the Status of Women. Gender justice for women in the media requires collaboration among media specialists, women's groups, researchers, nongovernmental organizations, and local and regional networks.

Manilla Bay is in partial sunglint along the left edge of the frame. The extensive flows of volcanic ash (lahars) extending from the mountain are readily seen despite partial cloud cover. The ash is mobilized with every rain in this typhoon-ridden region, flowing down valleys, filling drainage channels, and covering fields and towns. The STS-68 crew obtained excellent photographs of the region, for comparison to the radar data also obtained on the mission. Photographs in sunglint have proven particularly helpful because they show the exact outlines of surface water, which provides a datum point for the radar returns.

    Blood lead (PbB) and hemoglobin levels (Hb) were determined in 40 battery repair/recycling shop workers, 16 radiator repair shop workers, and 20 children living in the immediate vicinity of these shops. Unexposed residents with similar socio-economic status were also investigated. Mean PbB level was significantly higher for battery workers when compared to radiator workers and unexposed adults. Among battery workers, 94% had PbB levels above the WHO permissible exposure limit of 40 {micro}g/dL for males and 30 {micro}g/dL for females. There was no demarcation between workplace and living quarters; therefore, workers' families were similarly exposed to hazards. Children living in the immediate vicinity of battery shops also had significantly higher mean PbB levels compared to radiator shop children and unexposed children. For workers with PbB > 40 {micro}g/dL, 90% were anemic. Linear regression showed a correlation between Hb level and log{sub 10}PbB. There was no significant relationship between anemia and blood lead in children. The authors conclude that radiator repair activities appeared to increase the body burden of lead, although not up to a level significantly different from unexposed counterparts. Battery recycling/repair activities, however, significantly increased blood lead levels in workers and their children.

Unexposed residents with similar socioeconomic status were also investigated. Mean PbB level was significantly higher for battery workers (54.23 microg/dL) when compared to radiator workers (20.04 microg/dL) and unexposed adults (12.56 microg/dL) (P<0.001). Among battery workers, 94% had PbB levels above the WHO permissible exposure limit of 40 microg/dL for males and 30 microg/dL for females. There was no demarcation between workplace and living quarters; therefore, workers' families were similarly exposed to hazards. Children living in the immediate vicinity of battery shops also had significantly higher mean PbB levels (49.88 microg/dL) compared to radiator shop children (11.84 microg/dL) and unexposed children (9.92 microg/dL). For workers with PbB > 40 microg/dL, 90% were anemic (Hb < 13 g/dL for males and <11.5 g/dL for females). Linear regression showed a correlation (r=-0.214; P=0.03) between Hb level and log(10)PbB. There was no significant relationship between anemia and blood lead in children (r=-0.146). We conclude that radiator repair activities appeared to increase the body burden of lead, although not up to a level significantly different from unexposed counterparts. Battery recycling/repair activities, however, significantly increased blood lead levels in workers and their children.

    The very active Taal Volcano is situated 60 km south of Metro Manila in the southern part of Luzon Island. Based on its frequent explosive eruptions and high potential hazards to nearby population of several million, Taal Volcano is chosen as one of the 15 most dangerous "Decade Volcanoes" in the world. We deployed a temporary seismic network consisting of 8 stations since March 2008. The temporal network was operated from late March 2008 to mid March 2010 and recorded over 2270 local earthquakes. In the early data processing stages, unexpected linear drifting of clock time was clearly identified from ambient noise cross-correlation functions for a number of stations. The drifting rates of all problematic stations were determined as references to correct timing errors prior to further processing. Initial locations of earthquakes were determined from manually picking P- and S-phases arrivals with a general velocity model based on AK135. We used travel times of 305 well-located local events to derive a minimum 1-D model using VELEST. Two major earthquake groups were noticed from refined locations. One was underneath the western shore of Taal Lake with a linear feature, and the other spread at shallower depths showing a less compact feature around the eastern flank of Taal Volcano Island. We performed seismic tomography to image the 3D structure beneath Taal Volcano using a well-established algorithm, LOTOS. Some interesting features are noted in the tomographic results, such as a probable solidified past magma conduit below the northwestern corner of Taal Volcano Island, characterized by high Vp, Vs, and low Vp/Vs ratio, and a potential large hydrothermal reservoir beneath the central of Taal Volcano Island, characterized by low Vs and high Vp/Vs ratio. Combining the results of seismicity and tomographic images, we also suggest the potential existence of a magma chamber beneath the southwestern Taal Lake, and a magma conduit or fault extending from there to the

    This study assessed the book collection of five selected medical libraries in the Philippines, based on Doodys' Essential Purchase List for basic sciences and clinical medicine, to compare the match and non-match titles among libraries, to determine the strong and weak disciplines of each library, and to explore the factors that contributed to the percentage of match and non-match titles. List checking was employed as the method of research. Among the medical libraries, De La Salle Health Sciences Institute and University of Santo Tomas had the highest percentage of match titles, whereas Ateneo School of Medicine and Public Health had the lowest percentage of match titles. University of the Philippines Manila had the highest percentage of near-match titles. De La Salle Health Sciences Institute and University of Santo Tomas had sound medical collections based on Doody's Core Titles. Collectively, the medical libraries shared common collection development priorities, as evidenced by similarities in strong areas. Library budget and the role of the library director in book selection were among the factors that could contribute to a high percentage of match titles.

    Chemical inducement and DDRT-PCR (differential display reverse transcription PCR) are adopted to investigate the effect of epinephrine (EPI) on the settlement and metamorphosis of Manila clam larvae. Chemical inducement shows that EPI has an effect to some extent on the metamorphosis of Manila clam larvae at all concentrations and in all treatments designed. The most significant result of inducement is obtained at the concentration of 10-6 mol L-1 and for 4h. DDRT-PCR using six primer pairs shows that the gene expression pattern is quite different between EPI treatment and the control. Three hundred and forty-three amplification bands are obtained in total, among which, 67 (19.53%) are differentially appeared. Therefore, EPI has an effect on the gene expression of the eye spot larval Manila clam. It can be hypothesized that EPI is a settlement and metamorphosis inducer for Manila clam. EPI may lead to larvae settlement and metamorphosis by binding to the receptors on the membrane and then changing the gene expression of larvae cells.

  5. Spanish Jesuits in the Philippines: geophysical research and synergies between science, education and trade, 1865-1898.

    In 1865, Spanish Jesuits founded the Manila Observatory, the earliest of the Far East centres devoted to typhoon and earthquake studies. Also on Philippine soil and under the direction of the Jesuits, in 1884 the Madrid government inaugurated the first Meteorological Service in the Spanish Kingdom, and most probably in the Far East. Nevertheless, these achievements not only went practically unnoticed in the historiography of science, but neither does the process of geophysical dissemination that unfolded fit in with the two types of transmitter of knowledge identified by historians in the missionary diffusion of the exact sciences in colonial contexts. Rather than regarding science as merely a stimulus to their functionary and missionary tasks, Spanish Jesuits used their overseas posting to produce and publish original research--feature that would place them within the typology of the 'seeker' rather than the 'functionary' (in stark contrast to what the standard typology sustains). This paper also analyses examples of synergies between science, education and trade, which denotes, inter alia, the existence of a broad and solid educational structure in the Manila Mission that sustained the strength of research enterprise.

    Leptospirosis is caused by pathogenic species of Leptospira. The aim of this study was to determine and characterize the pathogenicity of four dominant Leptospira isolates prevailing among rats in the Philippines. The isolates were Leptospira interrogans serovar Manilae strain K64, L. interrogans serovar Losbanos strain K37, L. interrogans serovar Ratnapura strain K5 and Leptospira borgpetersenii serovar Javanica strain K6. Pathogenicities were studied using hamsters, which reproduce severe human leptospirosis. The minimum lethal doses were 10(0) ( = 1) leptospires for K64, K37 and K5, and 10(1) leptospires for K6. Weight loss amongst the Leptospira-infected hamsters was observed from 1 day before death (K64-, K37- and K5-infected hamsters) to as much as 1 week before death for K6-infected hamsters. Similar and varied gross and microscopic lesions were observed amongst infected hamsters, even for strains belonging to the same species (i.e. L. interrogans). The most significant and common histopathological findings were congestion of the glomerulus, disarrangement of hepatic cords and erythrophagocytosis. Other findings were foamy splenic macrophages for K6, severe petechial pulmonary haemorrhage for K64, and hematuria and severe pulmonary congestion for K37. Immunostaining and culture revealed the presence of leptospires in different organs of the infected hamsters. Based on these results, Leptospira isolates from rats in the Philippines were shown to be highly virulent, causing pulmonary haemorrhage, severe hepato-renal damage and death in hamsters even at lower doses. The present findings on experimental leptospirosis support clinical data showing that patients with severe manifestations of leptospirosis, such as pulmonary haemorrhage, are increasing in the Philippines. These findings may serve as a basis to strengthen the early diagnosis and treatment of human leptospirosis.

    Violence against women is recognized by globally as a serious health and social problem that impedes development. To determine the magnitude of physical intimate partner violence against women in six selected communities from Chile, Egypt, India and the Philippines. Population-based household surveys. Selected urban communities in Temuco, Chile; Ismailia, Egypt; Lucknow, Trivandrum, and Vellore non-slum areas of India; and in Manila, the Philippines. Women aged 15-49 years who cared for at least one child younger than 18 years old. The number of participants per community was 442 (Santa Rosa, Chile), 631 (El-Sheik Zayed, Egypt), 506 (Lucknow, India), 700 (Trivandrum, India), 716 (Vellore, India) and 1000 (Paco, the Philippines). Lifetime and Current physical intimate partner violence (IPV) was measured using standard definitions and four behaviors of actions--namely slap, hit, kick and beat. Three derived variables for severity included: disabling IPV, IPV-related injury requiring health care and multiple severe IPV (presence of hit and kick and beat). Percentages of lifetime and current physical intimate partner violence (IPV) against women in our sample of 3975 were as follows: 24.9 and 3.6 (Santa Rosa), 11.1 and 10.5 (El-Sheik Zayed), 34.6 and 25.3 (Lucknow), 43.1 and 19.6 (Trivandrum) 31.0 and 16.2 (Vellore), and 21.2 and 6.2 (Paco). Multiple severe physical IPV was more common in the three communities within India (9.0%, 5.9% and 8.0% in Trivandrum, Lucknow and Vellore) than the other three communities (Santa Rosa 2.1%; El-Sheik Zayed 2.9% and Paco 1.9%). Physical IPV was found to be a common phenomenon in all six communities. Overall, patterns of IPV behaviors were similar among the six communities.

    Lymphatic filariasis caused by Wuchereria bancrofti and Brugia malayi is endemic throughout most of the southern half of the Philippine archipelago. Economic and manpower shortages prior to 1996 made it difficult to acquire new prevalence data and vector control data concurrently from all provinces. Nevertheless, analysis of cumulative prevalence data on filariasis indicates the persistence of filariasis in each of the three major island groups - Luzon, Visayas and Mindanao - including 45 out of 77 provinces. Here, Michael Kron and colleagues summarize the prevalence data, and review host, parasite and vector characteristics relevant to the design and implementation of disease control initiatives in the Philippines planned for the year 2000.

    2014-01-01

    Each year, there are approximately 1.24 million deaths due to road traffic injuries, the majority of which occur in low- and middle-income countries. Since 2008, 35 countries have passed legislation to implement road safety strategies. However, many countries have yet to pass comprehensive legislation while others lack adequate enforcement of current policies. The annual global mortality rate due to road trauma remains unacceptably high and reflects the need for governments to prioritize the passage and implementation of road safety legislation. Alcohol is a leading risk factor for road trauma globally and the leading cause of death and disability in the Western Pacific region. Despite the overwhelming evidence that strict enforcement of drunk-driving policies can lead to a drastic reduction in alcohol-related road incidents, many countries in the Western Pacific lack sufficient data that could facilitate the design of appropriate drunk-driving interventions. This paper provides an analysis of the current status of policies and attitudes related to alcohol and road injuries throughout the Western Pacific region, with a specific focus on the Philippines. Following the passage of drunk-driving legislation in 2013, a medical records review of alcohol-related road trauma patients in Manila Doctors Hospital was conducted. The findings of this pilot project further highlight the pervasive problem of missing or unreliable data regarding alcohol’s role in road trauma. Assessing the burden of drunk driving is an important step in designing effective interventions and systematically changing attitudes about driving under the influence. PMID:25191146

    1990-09-01

    The Philippine Sea plate includes plateaus of thickened crust interpreted as imbricated ophiolite and arc-related terranes of late Mesozoic-early Tertiary age separated by thinner oceanic crust. The arrival of plateaus at the subducting southwest margin of the Philippine Sea plate has caused the Philippine Trench to propagate southward in increments and caused transfer of terranes to the Philippine margin. New data from the Halmahera region indicate that the position, nature and evolution of plate boundaries have been strongly influenced by the heterogeneous character of the Philippine Sea plate. At present the Philippine Trench terminates at an oceanic plateau which is structurally continuous with an old forearc and ophiolite terrane on Halmahera. The position of this terrane has caused Philippine Sea plate-Eurasia convergence to be transferred from subduction at the Philippine Trench to the Molucca Sea Collision Zone through a broad NE-SW dextral transpressional zone across Halmahera. This plate boundary configuration is unstable and requires the future development of a new subduction zone to the east of Halmahera which will result in amalgamation of the Halmahera ophiolite terrane to the Philippine margin. In the Halmahera region amalgamation of terranes to the evolving Philippine microcontinent is currently in process.

    We introduce a focus+context method to visualize a complicated metro map of a modern city on a small displaying area. The context of our work is with regard the popularity of mobile devices. The best route to the destination, which can be obtained from the arrival time of trains, is highlighted. The stations on the route enjoy larger spaces, whereas the other stations are rendered smaller and closer to fit the whole map into a screen. To simplify the navigation and route planning for visitors, we formulate various map characteristics such as octilinear transportation lines and regular station distances into energy terms. We then solve for the optimal layout in a least squares sense. In addition, we label the names of stations that are on the route of a passenger according to human preferences, occlusions, and consistencies of label positions using the graph cuts method. Our system achieves real-time performance by being able to report instant information because of the carefully designed energy terms. We apply our method to layout a number of metro maps and show the results and timing statistics to demonstrate the feasibility of our technique. © 2011 IEEE

    A two-dimensional ocean bottom seismometer (OBS) survey was performed in 2015, along an E-W trending line (OBS2015-2) located in front of the Manila subduction zone. The preliminary results show that OBS data are of high quality for the whole experiment. Seismic phases (such as Pg and PmP) are very clear in the OBSs' record sections. They are further identified by forward modeling using the Rayinvr software. The reflective seismic phases from the Moho interface (PmP) are observed in all OBS sections. The identification of these PmP phases used simultaneously with Fast and Tomo2D tomography results shows that the nature of the crust is essentially continental, not oceanic, except perhaps close to the trench. The obvious PmP phases in the incoming plate along the Manila Trench subduction zone, will further provide good constraints concerning the nature and evolution of the incoming plate in the Manila subduction zone. This research was granted by the Natural Science Foundation of China (91428204, 41176053) and the scientific cruise (NORC2015-8) by the R/V Shiyan 2.

    A numerical taxonomic study of halophilic Vibrio isolated from healthy and brown ring disease (BRD) affected manila clams (Ruditapes philippinarum), harvested from the Atlantic coast of south-western Spain, was performed. Characterization of 123 presumptive Vibrio spp. was carried out using 94 phenotypic tests. Simple matching and Jaccard similarity coefficients were used for numerical analysis. Cluster analysis by the unweighted pair group method with arithmetic averages yielded 15 phena defined at 0.81 similarity. Large phena corresponded to Vibrio tubiashii, V. splendidus biotype I and V. harveyi (phena 1, 5 and 9, respectively). The species V.splendidus biotype II, V. natriegens, V. mediterranei and V. alginolyticus were also represented. The inhibitory effect of diffusible extracellular products of the isolates against 27 strains of V.tapetis, the aetiological agent of BRD, was also investigated. Only five V. tubiashii isolates inhibited the growth of V. tapetis strains. The antimicrobial effect was inhibited by heating and depended on the culture medium. The main Vibrio species associated with manila clams were V. tubiashii, V.spendidus and V. harveyi. The antagonistic relationship established between V. tapetis and the Vibrio spp. clam microbiota may explain the failure of isolation in plating medium of V.tapetis from BRD-affected clams on the south Atlantic coast of Spain. Some of the strains isolated from manila clams correspond to agarolytic strains that constitute phenon 7 and they do not fit into any of the currently described Vibrio species.

    The Manila clam, Ruditapes philippinarum, is an economically important shellfish in marine aquaculture, with a broad thermal tolerance. The ability to cope with cold stress is quite important for the survival of aquatic species under natural conditions. A cold-tolerant clam that can survive the winter at temperatures below 0 °C might extend our understanding of the mechanisms underlying the response to cold stress. In this study, the transcriptional response of the Manila clam to cold stress (-1 °C) was characterized using RNA sequencing. The transcriptomes of a cold-treatment (O) group of clams, which survived under cold stress, and the control group (OC2), which was not subjected to cold stress, were sequenced with the Illumina HiSeq platform. In all, 148,593 unigenes were generated. Compared with the unigene expression profile of the control group, 1760 unigenes were up regulated and 2147 unigenes were down regulated in the O group. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses revealed that signal transduction, mitochondrial metabolism, cellular component organization or biogenesis, and energy production processes were the most highly enriched pathways among the genes that were differentially expressed under cold stress. All these pathways could be assigned to the following biological functions in the cold-tolerant Manila clam: signal response to cold stress, antioxidant response, cell proliferation, and energy production.

    According to the hologenome theory, the microbiota contributes to the fitness of the holobiont having an important role in its adaptation, survival, development, health, and evolution. Environmental stress also affects the microbiota and its capability to assist the holobiont in coping with stress factors. Here, we analyzed the diversity of cultivable bacteria associated with Manila clam tissues (mantle, gills, hemolymph) in two non-contaminated sites (Portugal and France) and one metal-contaminated site (Portugal). A total of 240 isolates were obtained. Representative isolates (n = 198) of the overall diversity were identified by 16S rDNA sequencing and subjected to functional characterization. Isolates affiliated with Proteobacteria, Actinobacteria, Firmicutes, and Bacteroidetes. Proteobacteria (mostly Pseudoalteromonadaceae and Vibrionaceae) were dominant in non-contaminated sites while Actinobacteria (mostly Microbacteriaceae) dominated in the metal-contaminated site. The main factor affecting the microbiota composition was contamination. No significant differences were observed between clam tissues and geographic regions. Several isolates tested positive for antibacterial activity, biofilm formation, protease, and siderophore production. The results show that the Manila clam harbors a diverse microbiota that may contribute to clam protection and overall fitness, as well as to its adaptation to stressful environments. In addition, the Manila clam microbiota is revealed as a promising source of novel probiotics with potential application in aquaculture.

    This paper reports that the Philippines' downstream sector is poised for sharp growth. Despite a slip in refined products demand in recent years, Philippines products demand will rebound sharply by 2000, East-West Center (EWC), Honolulu, predicts. Philippines planned refinery expansions are expected to meet that added demand, EWC Director Fereidun Fesharaki says. Like the rest of the Asia-Pacific region, product specifications are changing, but major refiners in the area expect to meet the changes without major case outlays. At the same time, Fesharaki says, push toward deregulation will further bolster the outlook for the Philippines downstream sector.

    Modern seismicity record along the Manila Trench shows only infrequent Mw7 earthquakes, the lack of great earthquakes may indicate the subduction fault is either aseismically slipping or is accumulating strain energy toward rapid release in a megathrust earthquake. We conduct numerical simulations of the plate coupling, earthquake nucleation and dynamic rupture propagation processes along the Manila subduction fault (15-19.5ºN), taking into consideration the effects of plate geometry (including subducted seamounts), fault strength, rate-state frictional properties and pore pressure variations. Specifically, we use the bathymetry to depict the outline of Manila trench along its strike, 2681 background seismicity (1970/02/13 to 2013/09/06) from Chinese Earthquake Network Center and 540 focal mechanism solutions (1976/01/01 to 2013/01/27) from Global CMT project to constrain the geometry of the subducting Sunda/Eurasian slab. The compilation of seismicity and focal mechanism indicates the plate dipping angle gradually changes from 28º (south of the Scaborough Seamount Chain) to 12º (north of it). This geometric anomaly may due to the subducted part of the seamount chain. Preliminary modeling results using gabbro gouge friction data show that the Scaborough Seamount Chain could be a barrier to earthquake rupture propagation. Only earthquakes larger than Mw7 can overcome the barrier to rupture the entire Manila trench. Smaller earthquakes would cease rupturing when it encounters the seamount chain. Moreover, we propose that Manila trench subduction zone has the potential of rupturing in a Mw8 megathrust earthquake, if the simulation period is long enough for an Mw8 earthquake cycle and dynamic rupture overcomes the subducted Scaborough Seamount Chain. Our model parameters will be further constrained by laboratory rock mechanics experiments conducted on IODP Expedition 349, South China Sea (SCS), drilling samples (work in progress at China Earthquake Administration

    Concentrations of trace metals (Cu, Pb, Zn, Cd, Cr, Hg, and As) were determined for the first time in seawater, sediment, and Manila clam from Deer Island, Liaoning Province, China. The seawater, sediment, and clam samples were collected seasonally at three clam farming sites around Deer Island during 2010-2011. The average concentrations of Cu, Pb, Zn, Cd, Cr, Hg, and As in the seawater samples were 4.16, 0.72, 5.88, 0.45, 2.51, 0.03, and 1.02 μg/l, respectively. The seasonal variations of trace metals in seawater showed a significant difference in the concentrations of Cu, Pb, Zn, Hg, and As among seasons. The average concentrations of Cu, Pb, Zn, Cd, Cr, Hg, and As in the sediment samples were 6.43, 13.80, 53.08, 1.10, 36.40, 0.05, and 4.78 mg/kg dry weight, respectively. Trace metal concentrations in sediment seasonally varied significantly except for Cd and Hg. The average concentrations of Cu, Pb, Zn, Cd, Cr, Hg, and As in the clam samples were 11.28, 0.61, 92.50, 0.58, 3.98, 0.03, and 1.98 mg/kg dry weight, respectively. Concentrations of Cu, Zn, Cd, Cr, and As in Manila clam showed marked seasonal fluctuations with significant difference. Cu and Zn were the metals with the highest mean biosediment accumulation factor values in Manila clam. Besides, significant correlations for the concentrations of Cu and Zn relative to their concentrations in sediment were also found. Such differences in regression analyzes may be explained by differential bioaccumulation of essential and xenobiotic metals. Concentrations of trace metals in Manila clam did not exceed the maximum established regulatory concentrations for human consumption. Moreover, the calculations revealed that the estimated daily intake values for the examined clam samples were below the internationally accepted dietary guidelines and the calculated hazard quotient values were well less than 1, thus strongly indicating that health risk associated with the intake studied metals through the consumption

    Geothermal electrical plants currently in operation in the Philippines are presented. Following a brief review of the geographical and energy situation of the nation, attention is given to the first 55,000-kW unit of the Tiwi Geothermal Electric Plant, which commenced operation in January 1979, the portable 3,000-kE Leyte Geothermal Pilot Plant, which commenced operation in July, 1977 as the first geothermal power plant in the country, the Makiling-Banahaw (Mak-Ban) Geothermal Power Plant, the first 55,000-kW unit of which began operation in May, 1979 and the second 55,000-kW unit of the Tiwi plant, which came into service in June, 1979, thus making the Philippines the fourth largest producer of geothermal electricity in the world. Factors favoring the use of geothermal plants in developing nations are pointed out, including low capital costs, no foreign exchange costs for fuel, small units, and little environmental impact, and the start-up of two more plants, the second 55,000-kW unit at Mak-Ban in September 1979 and the third Tiwi unit in January 1980, are noted. It is predicted that in 1981, when the Philippines is expected to become the largest user of geothermal energy from hot-water fields, it will have a total capacity of 552 MW from the Mak-Ban, Tiwi and Leyte sites. Further areas with geothermal potential are also pointed out.

    Objectives This study assessed the book collection of five selected medical libraries in the Philippines, based on Doodys’ Essential Purchase List for basic sciences and clinical medicine, to compare the match and non-match titles among libraries, to determine the strong and weak disciplines of each library, and to explore the factors that contributed to the percentage of match and non-match titles. Method List checking was employed as the method of research. Results Among the medical libraries, De La Salle Health Sciences Institute and University of Santo Tomas had the highest percentage of match titles, whereas Ateneo School of Medicine and Public Health had the lowest percentage of match titles. University of the Philippines Manila had the highest percentage of near-match titles. Conclusion De La Salle Health Sciences Institute and University of Santo Tomas had sound medical collections based on Doody’s Core Titles. Collectively, the medical libraries shared common collection development priorities, as evidenced by similarities in strong areas. Library budget and the role of the library director in book selection were among the factors that could contribute to a high percentage of match titles. PMID:28096742

    In order to determine whether growth performance could be improved by hybridizing full-sib families of Manila clam ( Ruditapes philippinarum), crosses between two full-sib families including self and reciprocal crosses were carried out. The effects of heterosis, combining ability and interaction on the growth of shell length were estimated. The results showed that the growth of hybrid larvae was intermediate between parents on days 6 and 9. Heterosis on shell length was observed, which varied at juvenile stage. The cross of ♂A × ♀B ( Hp varied between 10.41% and 68.27%) displayed larger heterosis than ♂B × ♀A ( Hp varied between 1.89% and 32.33%) did, suggesting that ♂A × ♀B was an ideal hatchery method of improving the growth performance of Manila clam. The variances of general combining ability (GCA), special combining ability (SCA) and interaction (I) were significant in shell length (P < 0.05), indicating that both additive and non-additive genetic factors were important contributors to the growth of larvae and juveniles. The GCA for shell length of ♂A × ♀B was higher than that of ♂B × ♀A at both larval and juvenile stages. This confirmed that the cross between ♂A and ♀B showed great growth in shell length. In summary, the growth of Manila clam seeds could be improved by hybridizing selected parents from large numbers of full-sib families.

    The assessment of marine environmental health is a complex but fundamental task both for ecosystem conservation and food safety related to the human consumption of marine products. Manila clams inhabiting the Venice Lagoon constitute an excellent case study for evaluating the effects of complex mixtures of industrial and urban effluents on aquatic organisms. Clams were collected in different seasons at four locations within the Venice Lagoon. The sampling sites were characterized by a range of pollutant concentrations and included Porto Marghera, a highly polluted industrial area where clam harvesting for human consumption is strictly forbidden. Pooled soft tissues were subjected to mass spectroscopy analysis to measure the concentrations of PCDDs/PCDFs/PCBs-DL, PCBs, PBDEs, HCB and PAHs, and pooled digestive gland samples were used for gene expression profiling. While seasonal variation was found to be responsible for the largest proportion of transcriptional changes, significance analysis of microarrays quantitative correlation analysis identified 162 transcripts that were correlated with at least one class of chemicals measured in the samples from the four different sampling sites. Prediction Analysis of Microarrays (PAM) identified a minimal set of seven genes that correctly assigned samples collected in the restricted polluted area (Porto Marghera), independent of the season in which they were collected. An integrated approach combining transcriptomics and chemical analyses of the Manila clam provided a global picture of how Manila clams respond to complex mixtures of xenobiotics and their interplay with other biotic and abiotic factors. We were also able to identify gene expression signatures for different classes of chemicals and a set of robust biomarkers of exposure to these chemicals.

    The Manila clam, Ruditapes philippinarum, is one of the major aquaculture species in the world and a potential sentinel organism for monitoring the status of marine ecosystems. However, genomic resources for R. philippinarum are still extremely limited. Global analysis of gene expression profiles is increasingly used to evaluate the biological effects of various environmental stressors on aquatic animals under either artificial conditions or in the wild. Here, we report on the development of a transcriptomic platform for global gene expression profiling in the Manila clam. A normalized cDNA library representing a mixture of adult tissues was sequenced using a ultra high-throughput sequencing technology (Roche 454). A database consisting of 32,606 unique transcripts was constructed, 9,747 (30%) of which could be annotated by similarity. An oligo-DNA microarray platform was designed and applied to profile gene expression of digestive gland and gills. Functional annotation of differentially expressed genes between different tissues was performed by enrichment analysis. Expression of Natural Antisense Transcripts (NAT) analysis was also performed and bi-directional transcription appears a common phenomenon in the R. philippinarum transcriptome. A preliminary study on clam samples collected in a highly polluted area of the Venice Lagoon demonstrated the applicability of genomic tools to environmental monitoring. The transcriptomic platform developed for the Manila clam confirmed the high level of reproducibility of current microarray technology. Next-generation sequencing provided a good representation of the clam transcriptome. Despite the known limitations in transcript annotation and sequence coverage for non model species, sufficient information was obtained to identify a large set of genes potentially involved in cellular response to environmental stress.

    2005-01-24

    A Bragg fiber design with potential for applications in metro networks is proposed for the first time. The average dispersion of the designed fiber is 10 ps/km.nm in the C-band, and in view of its estimated loss being very low, such a Bragg fiber should enable ultra low-loss DWDM transmission over 100 km at 10 Gbits/s. A Bragg fiber based metro network is an attractive proposition because it would not require any amplifier and dispersion compensator for distances approximately 100 km. This should significantly reduce installation and operational cost, and complexity of a metro network.

He notes progress on two fronts: recently enacted legislation regulating physician prescribing practices will improve access by the poor to prescription drugs, and national guidelines on biomedical research provide for the establishment of a National Ethics Committee dominated by nonphysicians.

    On June 15, 1991, Mount Pinatubo in the Philippines exploded in the second largest volcanic eruption on Earth this century. This eruption deposited more than 1 cubic mile (5 cubic kilometers) of volcanic ash and rock fragments on the volcano's slopes. Within hours, heavy rains began to wash this material down into the surrounding lowlands in giant, fast-moving mudflows called lahars. In the next four rainy seasons, lahars carried about half of the deposits off the volcano, causing even more destruction in the lowlands than the eruption itself.

  5. Development of Manila Hemp Fiber Epoxy Composite with High Tensile Properties Through Handpicking Fiber Fragments

    Manila hemp fibers are separated to several sequent fragments from single fiber. The tensile strength of each fiber fragments and their epoxy composite are measured, followed by scanning electronic microscopic (SEM) analysis. The results show that the tensile strength of fiber fragments is almost constant along fiber. For composite, the tensile strength first increases and then decreases at the position near to root. The Young's modulus presents increasing with location from root to top for fiber and composite. Microstructure analysis indicates that the difference of tensile properties between fiber fragments derive from the difference of fiber diameter.

    Fabricated all sky imagers are efficient and cost effective instruments for cloud detection and classification. Continuous operation of this instrument can result in the determination of cloud occurrence and cloud base heights for the paired system. In this study, a fabricated paired sky imaging system - consisting two commercial digital cameras (Canon Powershot A2300) enclosed in weatherproof containers - is developed in Manila Observatory for the purpose of determining cloud base heights at the Manila Observatory area. One of the cameras is placed on the rooftop of Manila Observatory and the other is placed on the rooftop of the university dormitory, 489m from the first camera. The cameras are programmed to simultaneously gather pictures every 5 min. Continuous operation of these cameras were implemented since the end of May of 2014 but data collection started end of October 2013. The data were processed following the algorithm proposed by Kassianov et al (2005). The processing involves the calculation of the merit function that determines the area of overlap of the two pictures. When two pictures are overlapped, the minimum of the merit function corresponds to the pixel column positions where the pictures have the best overlap. In this study, pictures of overcast sky prove to be difficult to process for cloud base height and were excluded from processing. The figure below shows the initial results of the hourly average of cloud base heights from data collected from November 2013 to July 2014. Measured cloud base heights ranged from 250m to 1.5km. These are the heights of cumulus and nimbus clouds that are dominant in this part of the world. Cloud base heights are low in the early hours of the day indicating low convection process during these times. However, the increase in the convection process in the atmosphere can be deduced from higher cloud base heights in the afternoon. The decrease of cloud base heights after 15:00 follows the trend of decreasing solar

    An individual-based mathematical model was developed to investigate the biological and environmental interactions that influence the prevalence and intensity of Brown Ring Disease (BRD), a disease, caused by the bacterial pathogen, Vibrio tapetis, in the Manila clam (Venerupis (= Tapes, = Ruditapes) philippinarum). V. tapetis acts as an external microparasite, adhering at the surface of the mantle edge and its secretion, the periostracal lamina, causing the symptomatic brown deposit. Brown Ring Disease is atypical in that it leaves a shell scar that provides a unique tool for diagnosis of either live or dead clams. The model was formulated using laboratory and field measurements of BRD development in Manila clams, physiological responses of the clam to the pathogen, and the physiology of V. tapetis, as well as theoretical understanding of bacterial disease progression in marine shellfish. The simulation results obtained for an individual Manila clam were expanded to cohorts and populations using a probability distribution that prescribed a range of variability for parameters in a three dimensional framework; assimilation rate, clam hemocyte activity rate (the number of bacteria ingested per hemocyte per day), and clam calcification rate (a measure of the ability to recover by covering over the symptomatic brown ring deposit), which sensitivity studies indicated to be processes important in determining BRD prevalence and intensity. This approach allows concurrent simulation of individuals with a variety of different physiological capabilities (phenotypes) and hence by implication differing genotypic composition. Different combinations of the three variables provide robust estimates for the fate of individuals with particular characteristics in a population that consists of mixtures of all possible combinations. The BRD model was implemented using environmental observations from sites in Brittany, France, where Manila clams routinely exhibit BRD signs. The simulated

    Using WHO definitions of visual loss and a standardised methodology, 256 children were examined in schools for the blind in Thailand (1 school) and the Philippines (3 schools). 244 (95%) were blind (BL) or severely visually impaired (SVI). Causes of SVI and blindness were classified anatomically and aetiologically, and avoidable causes identified. Causes of visual loss in Khon Kaen, Thailand (n = 65) and Manila, Philippines, (n = 113) were similar, with conditions of the whole globe accounting for 27.7 and 27.4% of SVI/BL; retinal disease 29.2 and 23.0%; cataract 16.9 and 16.8%; corneal disease 12.3 and 13.4%; and optic nerve disease and glaucoma 6.2 and 8.8%. Perinatal factors accounted for 20.0 and 23.0% of SVI/BL; hereditary disease 13.8 and 17.7%; and 12.3 and 15.0% was due to events occurring during childhood. The underlying aetiology could not be determined in 50.8 and 41.6% of cases, respectively. In the two schools together twenty six children (15%) were blind from retinopathy of prematurity (ROP) and 16 (9%) from corneal scarring attributed to Vitamin A deficiency. 103 of 178 (58%) children had avoidable causes of visual loss. In the Filipino towns of Baguio and Davao (n = 66), the causes of visual loss were different from those in Khon Kaen and Manila, with 54.8 and 42.9% of SVI/BL being due to corneal disease, and only 3.2 and 8.5% to retinal disease.(ABSTRACT TRUNCATED AT 250 WORDS)

    Whilst being hailed as the remedy to the world’s ills, cities will need to adapt in the 21st century. In particular, the role of public transport is likely to increase significantly, and new methods and technics to better plan transit systems are in dire need. This paper examines one fundamental aspect of transit: network centrality. By applying the notion of betweenness centrality to 28 worldwide metro systems, the main goal of this paper is to study the emergence of global trends in the evolution of centrality with network size and examine several individual systems in more detail. Betweenness was notably found to consistently become more evenly distributed with size (i.e. no “winner takes all”) unlike other complex network properties. Two distinct regimes were also observed that are representative of their structure. Moreover, the share of betweenness was found to decrease in a power law with size (with exponent 1 for the average node), but the share of most central nodes decreases much slower than least central nodes (0.87 vs. 2.48). Finally the betweenness of individual stations in several systems were examined, which can be useful to locate stations where passengers can be redistributed to relieve pressure from overcrowded stations. Overall, this study offers significant insights that can help planners in their task to design the systems of tomorrow, and similar undertakings can easily be imagined to other urban infrastructure systems (e.g., electricity grid, water/wastewater system, etc.) to develop more sustainable cities.

  12. Contraceptive practice in the Philippines.

    PubMed

    1989-01-01

    Contraceptive use increased substantially in the Philippines from 1983 to 1986. Prevalence increased 32.1% in 1983, 45.7% in 1986. Increase in use was among married women in Northern Mindanao, Central Visayas, Southern Tagalog, Bicol, and Western Mindanao. Prevalence remained unchanged in Southern Mindanao. During this period, modern contraceptive methods also increased with more women opting to use the pill, IUD, injectables, and sterilization. In most areas in the Philippines, contraceptive use escalated with the more traditional methods like rhythm and withdrawal. Modern family planning increased most in urban areas such as Northern and Western Mindanao. Age also played a significant part in the study. Women aged 20-24 increased usage between 1983 and 1986. A more substantial increase was noticed in the 25-49 year old group, and the highest increase came from married women aged 30-34, with at least 3-4 children, during 1983. This figure shifted in 1986 with contraceptive use becoming more pronounced among 35-39 year olds. Modern methods declined at the 40-44 age bracket due to low fecundity. Throughout the country, modern contraceptive methods were more widely practiced by working women and was defined occupationally. Women in production, labor, and service occupations displayed a low level of modern usage, while those women in professional, administrative, and technical positions were more likely to use modern methods.

    Microplastics, plastic particles <5 mm, are an emerging concern in aquatic ecosystems. Because microplastics are small, they are available to many filter-feeding organisms, which can then be consumed by higher trophic level organisms, including humans. This study documents the quantity of microplastics present in wild and cultured Manila clams (Venerupis philippinarum). Three active shellfish farms and three reference beaches (i.e., non-shellfish farm sites) in Baynes Sound, British Columbia were chosen to examine the microplastic concentrations in wild and cultured Manila clams. Microplastics were isolated using a nitric acid digestion technique and enumerated from 54 clams (27 farmed and 27 non-farmed). Qualitative attributes, such as colour and microplastic type (fiber, fragment, or film) also were recorded. There was no significant difference (F = 1.29; df = 1,4; P = 0.289) between microplastic concentrations in cultured and wild clams. Microplastic concentrations ranged from 0.07 to 5.47 particles/g (from reference beach and shellfish farm clams, respectively). Fibers were the dominant microplastic (90 %); colourless and dark gray fibers were the most common colours observed (36 and 26 %, respectively). Although this indicates that microplastics are definitely present in seafood consumed by humans, shellfish aquaculture operations do not appear to be increasing microplastic concentrations in farmed clams in this region.

    Globally, the Manila clam (Ruditapes philippinarum) stands as the second most important bivalve species in fisheries and aquaculture. Native to the Pacific coast of Asia, it is now well-established in North America and Europe, where its on-going management reflects local economic interests. The historic record of transfers spans the 20(th) century and suggests sequential movement from Japan to North America, as a hitch-hiker on oysters, and then intentional introduction in Europe, but global genetic data are missing. We have studied mitochondrial DNA and microsatellite markers in nine populations from Asia, North America and Europe. The results from the two types of markers indicated a good concordance of present-day genetic structure with the reported history of clam transfers across continents, and no evidence of relevant concealed introductions from continental Asia in Europe and North America. However, European populations showed a loss of genetic variability and significant genetic differentiation as compared to their American counterparts. Our study shows that in spite of the increasing ease for species to spread out of their native range, in the case of the Manila clam this has not resulted in new invasion waves in the two studied continents.

    Four types of defensins were identified in Manila clam and designated as Rpdef1, Rpdef2, Rpdef3 and Rpdef4, which encoded a polypeptide of 49, 46, 45 and 42 amino acids, respectively. Sequence alignments indicated that Rpdef1 shared 46.9% identity with Rpdef2, 40.8% with Rpdef3, and 34.7% with Rpdef4. Analysis of transcript polymorphism showed that Rpdef3 accounted for about 60% frequency of Rpdefs occurrence in clams from three geographic origins (Dalian, Qingdao and Hangzhou). By quantitative real-time RT-PCR (qRT-PCR) analysis, the transcripts of Rpdefs were mainly detected in hemocytes and they responded sensitively to bacterial challenge in hemocytes. Evolutionary analysis indicated that all Rpdefs were under positive selection with positively selected basic amino acid residues detected in the C-terminal regions, which perhaps have a functional relevance by modifying the charge distribution of Rpdefs. The results also showed some lineages with dN/dS > 1, suggesting positive selection pressures existed in some lineages of phylogeny tree constructed by mollusk defensins. Overall, our results suggest that Rpdefs perhaps played important roles in host defense and positive selection is the major driving force in generating high diversity of defensins in the Manila clam.

    The aim of this work was to evaluate the efficacy of domestic cooking in inactivating Manila clams experimentally infected with human hepatitis A virus (HAV). Electronic temperature probes were positioned to measure the internal temperature of Manila clams during domestic cooking. Two batches were infected with 10(7) and 10(5) TCID50  ml(-1) of HAV. The infected whole-in-shell clams were divided into three replicates and cooked on a conventional stove both singularly and in group and removed from the pan at fixed intervals. Pools of three digestive glands were examined by virus isolation for three blind passages and cell culture supernatant tested with real-time PCR. Results showed that 2-min cooking by a traditional domestic method at a temperature close to 100°C, after the opening up of the valves of all the clams, can completely devitalize the HAV in high viral load-infected clams. This is the first study on inactivation of HAV in experimentally infected Manila clams subjected to domestic cooking. At present, labelling all lagoon products as 'requiring cooking before consumption' is highly recommended, but no specifications are given on how long and at what temperature they should be cooked. Considering the high commercial value of Manila clams, our results can provide both the producers and the consumer with useful indications on how to cook clams to prevent the risk of HAV foodborne illness. © 2016 The Society for Applied Microbiology.

    This paper reports that Alcorn International Inc., Houston, has disclosed a test of another hefty oil flow off Philippines. Alcorn last month completed its third high flowing delineation well in the West Linapacan area off Palawan Island. Development of West Linapacan field will help boost lagging Philippines oil production, which fell 31% in 1991 from 1990 levels. Philippines Office of Energy Affairs (OEA) also outlined other aspects of the country's oil and gas activity in 1991. Recent drilling successes have redirected the country's focus north to the West Linapacan area from older Northwest Palawan oil fields. Meantime, two geophysical survey and exploration contracts (GSECs) were awarded in 1991, and two service contracts (SCs) were relinquished during the year. Several seismic program were completed last year, and in agreement between Australia and Philippines will yield added seismic data during the next 3 years.

    In this paper, we investigate the random walks on metro systems in 28 cities from worldwide via the Laplacian spectrum to realize the trapping process on real systems. The average trapping time is a primary description to response the trapping process. Firstly, we calculate the mean trapping time to each target station and to each entire system, respectively. Moreover, we also compare the average trapping time with the strength (the weighted degree) and average shortest path length for each station, separately. It is noted that the average trapping time has a close inverse relation with the station’s strength but rough positive correlation with the average shortest path length. And we also catch the information that the mean trapping time to each metro system approximately positively correlates with the system’s size. Finally, the trapping process on weighted and unweighted metro systems is compared to each other for better understanding the influence of weights on trapping process on metro networks. Numerical results show that the weights have no significant impact on the trapping performance on metro networks.

  3. The complexity and robustness of metro networks

    Transportation systems, being real-life examples of networks, are particularly interesting to analyze from the viewpoint of the new and rapidly emerging field of network science. Two particular concepts seem to be particularly relevant: scale-free patterns and small-worlds. By looking at 33 metro systems in the world, this paper adapts network science methodologies to the transportation literature, and offers one application to the robustness of metros; here, metro refers to urban rail transit with exclusive right-of-way, whether it is underground, at grade or elevated. We find that most metros are indeed scale-free (with scaling factors ranging from 2.10 to 5.52) and small-worlds; they show atypical behaviors, however, with increasing size. In particular, the presence of transfer-hubs (stations hosting more than three lines) results in relatively large scaling factors. The analysis provides insights/recommendations for increasing the robustness of metro networks. Smaller networks should focus on creating transfer stations, thus generating cycles to offer alternative routes. For larger networks, few stations seem to detain a certain monopole on transferring, it is therefore important to create additional transfers, possibly at the periphery of city centers; the Tokyo system seems to remarkably incorporate these properties.

    This paper describes an automatic mechanism for drawing metro maps. We apply multicriteria optimization to find effective placement of stations with a good line layout and to label the map unambiguously. A number of metrics are defined, which are used in a weighted sum to find a fitness value for a layout of the map. A hill climbing optimizer is used to reduce the fitness value, and find improved map layouts. To avoid local minima, we apply clustering techniques to the map-the hill climber moves both stations and clusters when finding improved layouts. We show the method applied to a number of metro maps, and describe an empirical study that provides some quantitative evidence that automatically-drawn metro maps can help users to find routes more efficiently than either published maps or undistorted maps. Moreover, we have found that, in these cases, study subjects indicate a preference for automatically-drawn maps over the alternatives.

  5. Durability of Starch Based Biodegradable Plastics Reinforced with Manila Hemp Fibers.

    2011-02-25

    The biodegradability of Manila hemp fiber reinforced biodegradable plastics was studied for 240 days in a natural soil and 30 days in a compost soil. After biodegradability tests, weights were measured and both tensile strength tests and microscopic observation were performed to evaluate the biodegradation behavior of the composites. The results indicate that the tensile strength of the composites displays a sharp decrease for up to five days, followed by a gradual decrease. The weight loss and the reduction in tensile strength of biodegradable composite materials in the compost soil are both significantly greater than those buried in natural soil. The biodegradability of these composites is enhanced along the lower portion because this area is more easily attacked by microorganisms.

  6. The Politics of Pipes: The Persistence of Small Water Networks in Post-Privatization Manila

    NASA Astrophysics Data System (ADS)

    Cheng, Deborah

    This project examines the politics of water provision in low-income areas of large, developing cities. In the last two decades, water privatization has become a global paradigm, emerging as a potential means for addressing the urban water crisis. In Manila, the site of the world's largest water privatization project, service to low-income areas has improved significantly in the post-privatization era. But whereas expansion of a water utility typically involves the replacement of informal providers, the experience in Manila demonstrates that the rapid connection of low-income areas actually hinges, in part, on the selective inclusion and exclusion of these smaller actors. Based on an ethnography of the private utilities and community-based providers, I use the persistence of small water networks as a lens for exploring the limits of water privatization in Manila. I focus on what I call micro-networks---community-built infrastructure that extends the formal, private utilities into low-income neighborhoods that the utilities do not wish to serve directly. In such a setup, the utility provides water only as far as the community boundary; beyond that, the micro-network operator constructs internal infrastructure, monitors for leakage and theft, and collects bills. But while these communities may gain access to safer water, they are also subject to higher costs and heightened disciplinary measures. By tracing the ways in which the utilities selectively use micro-networks to manage sub-populations, I show how the utilities make low-income spaces more governable. Delegating localized water management to micro-network operators depoliticizes the utilities' roles, shifting the sociopolitical difficulties of water provision to community organizations, while allowing the utilities to claim that these areas are served. This research leads to three related arguments. First, the persistence of small water networks highlights lingering inequities in access to water, for micro

    Cellular and humoral immune parameters are often used as biomarkers to trace environmental and physiological stresses in marine bivalves. In this study, we compared various immune parameters of Manila clams ( Ruditapes philippinarum) under normal conditions and under a high level of desiccation, using flow cytometry. The immune parameters analyzed included, total hemocyte count, hemocyte mortality, hemocyte DNA damage, reactive oxygen species (ROS) production, and phagocytosis activity. Total hemocyte count, hemocyte DNA damage, and hemocyte mortality were significantly elevated among clams under high desiccation stress, while phagocytosis activity and spontaneous ROS production were significantly lower compared to those parameters of the control clams ( p<0.05). These data suggest that the immune parameters analyzed in this study well reflect the physiological status of clams.

    Seagrass seed bank plays a key role in the regeneration of new vegetation when seagrasses are removed by the natural or man-made disaster. Various factors may affect the development of sediment seed bank. We conducted a microcosm experiment to test the effects of burrowing and feeding activities of Manila clam, Ruditapes philippinarum on the burial of Zostera marina seeds in sediments. The effects of lasting time (3-hour, 1-day, 3-day, 7-day, 14-day and 28-day), clam density (0, 2, 4 and 8 clams with shell length of 3 cm in each microcosm) and clam size (shell length of 2, 3 and 4 cm at 4-clam density) on seed burial were examined in plastic microcosm cores (30 cm high × 10 in inner diameter) in a 28-day period. Results showed that the seed burial depth significantly increased with time, the density and the size of clams. No seeds were buried in the sediment in the cores without clams during the whole experiment period. For the 3-cm clams, about 91.61% of the seeds were buried in the sediment at the end of the experiment in the high-density treatment (8 clams at each core); while in the medium and low-density treatments (4 and 2 clams in each core, respectively), about 76.93% and 60.61% of the seeds were buried in the sediment, respectively. For the size treatments, large (4 cm) clams buried 89.56% of the seeds at the end of the experiment, much more than those of medium (3 cm, 76.93%) and small (2 cm, 61.50%) size clams. During the whole experiment period, nearly all of the buried seeds were at a depth of from 0 cm to 5 cm. These results suggested that Manila clam Ruditapes philippinarum may play an important positive role in seagrass seed bank dynamics in the field.

    This study assessed the effect of Brown Muscle Disease (BMD) on Manila clam Venerupis philippinarum fitness. BMD was discovered in 2005. It affects the posterior adductor muscle and leads to clam gaping and eventually death. Three statuses of clams were compared: buried individuals with no signs of BMD (BUR); clams at the surface of the sediment with no signs of BMD (SURF) and clams at the surface of the sediment exhibiting signs of brown muscle disease (BMD). Physiological (condition index), immune (hemocyte parameters) and molecular (gene expressions) parameters collected seasonally were analyzed and compared. Results demonstrated a seasonal pattern in condition index (CI) with peaks in spring/summer and decreases in autumn/winter. At each season, the highest CI was observed in BUR and the lowest CI was observed in BMD. In terms of immune response, phagocytosis rate and capacity were higher in clams with BMD whereas the health status of the clams did not influence the total hemocyte count. Genes involved in the immune system (comp, tnf, inter) were upregulated in clams with BMD. The molecular analysis of gill and posterior muscle showed higher mitochondrial metabolism (cox-1, 16S) in cells of infected clams, suggesting a stronger energetic demand by these cells. Finally, genes involved in oxidative stress response (cat, sod), detoxification (mt) and DNA repair (gadd45) were also overexpressed due to reactive oxygen species production. Most of the studied parameters underlined a cause-effect correlation between Manila clam health status (BUR, SUR, BMD) and physiological parameters. An important stress response was observed in BMD-infected clams at different scales, i.e. condition index, immune parameters and stress-related gene expression.

    In present study, the inbreeding depression ( ID) of growth and survival of Manila clam (Ruditapes philippinarum) was investigated at larval and juvenile stages. Nine inbred families ( A 2, B 2, C 2, D 2, E 2, F 2, G 2, H 2 and I 2) were established by mating within nine full-sib families with expected inbreeding coefficient of 0.25. Inbred families showed significant differences in shell length and hatching rate of D-larvae (straight-hinged larvae). The larvae of the nine inbred families grew slower than those of control group ( CG), and their ID value ranged from 0.81% ± 6.09% to 16.10% ± 1.49%. The ID value of larval survival rate varied between 27.47% ± 9.36% and 70.50% ± 13.66%. The ID was also detected for juvenile growth in A 2, B 2, C 2, and D 2, which ranged from 4.60 ± 2.21 to 17.71 ± 7.73. The A 2 family maintained the highest juvenile survival rate, whereas the other inbred families exhibited ID values varying between 62.79% ± 4.54% and 96.14% ± 0.87%. The linear relationship of estimated ID between growth and survival was negatively correlated ( R = -0.434, P < 0.05). The results of this study suggested that the ID of growth was common at the larval stage but was less prevalent at juvenile stage. In contrast, the ID of survival increased from larval to juvenile stage. A better understanding of the effect of inbreeding may aid to selective breeding of Manila clam.

    Aerosol optical properties and growth were measured during 2014 and 2016 New Year celebrations at Manila Observatory, Philippines. Measurements were done using a USB2000 spectrometer from 22:00 of 31 December 2013 to 03:00 of 01 January 2014 and from 18:00 of 31 December 2015 to 05:30 01 January 2016. A xenon lamp was used as a light source 150m from the spectrometer. Fireworks and firecrackers were the main sources of aerosols during these festivities. Data were collected every 60s and 10s for 2014 and 2016 respectively. The aerosol volume size distribution was derived using the parametric inversion method proposed by Kaijser (1983). The method is performed by selecting 8 wavelengths from 387.30nm to 600.00nm. The reference intensities were obtained when firework activities were considerably low and the air was assumed to be relatively clean. Using Mie theory and assuming that the volume size distribution is a linear combination of 33 bimodal lognormal distribution functions with geometric mean radii between 0.003um and 1.2um, a least-square minimization process was implemented between measured optical depths and computed optical depths. The 2016 New Year distribution showed mostly a unimodal size distribution (mean radius = 0.3um) from 23:00 to 05:30 (Fig. 1a). The mean Angstrom coefficient value during the same time interval was approximately 0.75. This could be attributed to a constant RH (100%) during this time interval. A bimodal distribution was observed when RH value was 94% from 18:30 to 21:30. The transition to a unimodal distribution was observed at 21:00 when the RH value changes from 94% to 100%. In contrast to the 2016 New Year celebration, the 2014 size distribution was bimodal from 23:30 to 02:30 (Fig 1b). The bimodal distribution is the result of firework activities before New Year. Aerosol growth was evident when the size distribution became unimodal after 02:30 (mean radius = 1.1um). The mean Angstrom coefficient, when the size distribution is

    Nearly 40 years of research provides an extensive body of evidence about human health, well-being, and improved function benefits associated with experiences of nearby nature in cities. We demonstrate the numerous opportunities for future research efforts that link metro nature, human health and well-being outcomes, and economic values. We reviewed the literature on urban nature-based health and well-being benefits. In this review, we provide a classification schematic and propose potential economic values associated with metro nature services. Economic valuation of benefits derived from urban green systems has largely been undertaken in the fields of environmental and natural resource economics, but studies have not typically addressed health outcomes. Urban trees, parks, gardens, open spaces, and other nearby nature elements-collectively termed metro nature-generate many positive externalities that have been largely overlooked in urban economics and policy. Here, we present a range of health benefits, including benefit context and beneficiaries. Although the understanding of these benefits is not yet consistently expressed, and although it is likely that attempts to link urban ecosystem services and economic values will not include all expressions of cultural or social value, the development of new interdisciplinary approaches that integrate environmental health and economic disciplines are greatly needed. Metro nature provides diverse and substantial benefits to human populations in cities. In this review, we begin to address the need for development of valuation methodologies and new approaches to understanding the potential economic outcomes of these benefits.

    2016-01-01

    Thoracic surgery in the Philippines followed the development of thoracic surgery in the United States and Europe. With better understanding of the physiology of the open chest and refinements in thoracic anesthetic and surgical approaches, Filipino surgeons began performing thoracoplasties, then lung resections for pulmonary tuberculosis and later for lung cancer in specialty hospitals dealing with pulmonary diseases—first at the Quezon Institute (QI) and presently at the Lung Center of the Philippines although some university and private hospitals made occasional forays into the chest. Esophageal surgery began its early attempts during the post-World War II era at the Philippine General Hospital (PGH), a university hospital affiliated with the University of the Philippines. With the introduction of minimally invasive thoracic surgical approaches, Filipino thoracic surgeons have managed to keep up with their Asian counterparts although the problems of financial reimbursement typical of a developing country remain. The need for creative innovative approaches of a focused multidisciplinary team will advance the boundaries of thoracic surgery in the Philippines. PMID:27651936

    Phosphogypsum (PG), the major waste material in phosphate fertilizer processing, has been known to contain enhanced levels of naturally-occurring radionuclides especially (226)Ra. The lack of radioactivity data regarding Philippine phosphogypsum and its environmental behavior in the Philippine setting has brought concern on possible contamination of groundwater beneath the phosphogypsum ponds in Isabel, Leyte, Philippines. The radioactivity of Philippine phosphogypsum was determined and the leaching of (226)Ra from phosphogypsum and through local soil was quantified. Level of (226)Ra in groundwater samples in Isabel, Leyte, Philippines was also quantified to address the primary concern. It was found that the (226)Ra activity in Philippine phosphogypsum is distributed in a wide range from 91.5 to 935 Bq/kg. As much as 5% of (226)Ra can be leached from Philippine PG with deionized water. In vitro soil leach experiments suggest that the soil in the phosphate fertilizer plant area would be able to deter the intrusion of (226)Ra into the water table. Compared to reported values of natural groundwater levels of (226)Ra, the concentration of this radionuclide in Isabel, Leyte groundwater suggest that there is no (226)Ra intrusion brought about by the presence of phosphogypsum ponds in the area.

    This paper reports that Kirkland As, Oslo, has received a geophysical survey and exploration contract (GSEC) in a sizzling exploration and development theater off the Philippines. The license covers about 6,000 sq miles of undisputed waters, with depths mostly less than 300 ft, and lies in the Reed Bank area off Northwest Palawan Island, where several major oil and gas strikes have been made recently. Kirkland has 1 year in which to carry out its seismic work commitment. The terms of the GSEC then give an option to drill one well in a 6 month period. Once the results have been analyzed, the company can either drill another well or enter into a service contract for the license. Kirkland has a 65% share in the license, with the remainder split between Philippine companies Philodrill Corp., Beguet Mining Corp. subsidiary Petrofields, and Seafront Resources Corp. The Philippines is one of Kirkland's main areas of activity, the Kirkland Commercial Manager Ralph Baxter.

    Now downgraded to a tropical depression, Typhoon Mitag can be seen at full strength in this true-color image taken on March 6, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The green islands in the lower left-hand corner of the image are the Philippines. The typhoon, which formed to the south, moved northward late last week and skirted dangerously close to the Philippines before turning northwest and dissipating in the Philippine Sea late this week. On Monday, March 4, 2002, the typhoon bore sustained winds of 160 kilometers (99 miles) per hour and gusts of up to 195 kilometers (121 miles) per hour. On average, roughly 20 tropical storms and typhoons pass through this region of the Pacific Ocean each year. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

    The hemocytes of invertebrates play key roles in both cellular and humoral immune reactions by phagocytosis or delivering immune factors such as lectin and anti-microbial peptides. Bacterial infection causes changes in components such as lectins, anti-bacterial peptides, and lysosomal enzymes of plasma or hemolymph in molluscs. Previously, we found that infection with the protozoan parasite, Perkinsus, increases lectin synthesis in hemocytes. In order to investigate the patterns of genes expressed in Manila clams (Ruditapes philippinarum) infected with the protozoan parasite Perkinsus olseni, we constructed a cDNA library and sequenced 1850 clones (expressed sequence tags). A total of 79 ESTs, were related to 29 functional immune genes such as C-type lectin, lysozyme, and cystatin B, in Manila clams. Lectins were the largest group of immune-function ESTs found in our Manila clams library. Among 7 lectin clones, two full length cDNAs of lectins were cloned. MCL-3, which is a simple C-type lectin composed of 151 amino acids, has a relatively short signal sequence of 17aa and single carbohydrate-recognition domain (CRD) of approximately 130 residues. It is highly homologous to eel C-type lectin. The sequence of mc-sialic acid-binding lectin consists of 168 amino acid residues with molecular weight of 19.2 and shows high homology to sialic acid-binding lectin from the snail, Cepaea hortensis. The expression of 7 different lectins in hemocytes was analyzed by RT-PCR using gene-specific primers. Hemocytes from Perkinsus-infected clam expressed different sets of lectins than with Vibrio infection. These results demonstrate that several lectins are involved in Manila clam innate immunity and different challenges induce expression of different lectins.

    This paper reports that Alcorn International Inc., Houston, is producing about 16,500 b/d of oil from West Linapacan A field in the South China Sea off the Philippines. The field's current production alone is more than fivefold the Philippines' total average oil flow of 3,000 b/d in 1991. It's part of a string of oil and gas strikes off Palawan Island that has made the region one of the hottest exploration/development plays in the Asia-Pacific theater.

    Recent studies of the southern end of the Philippine Trench using GLORIA sidescan sonar and single channel seismic data and geological studies on the island of Halmahera suggest that the trench is in the process of propagating south and that some of the ESE-WNW convergence is transferred via a broad NE-SW zone of dextral strike-slip across northern Halmahera into the Molucca Sea Collision Zone. NE-SW ridges and lineaments on the seafloor can be traced into major faults and structural trends on land. The bathymetric expression of the Philippine Trench is lost where it meets an oceanic plateau on the Philippine Sea Plate. This elevated and probably thickened plateau appears to have inhibited any further propagation of the trench southwards. To the north of the plateau there is a well-developed accretionary prism, but to the south deformation of sediments on the seafloor is less intense. A prominent ridge, with sediments passively banked up against it marks the southern limit of deformation associated with the Philippine Trench. To the south lies the eastern Halmahera-Waigeo Ophiolite Terrane, an area of shallow water and islands underlain by ophiolitic basement between Halmahera and the Sorong Fault Zone. There are no bathymetric or structural features to indicate any form of active link between the Philippine Trench and the Sorong Fault through or along the northern side of this ophiolite terrane. There is no earthquake evidence for any form of fault linking the Philippine Trench to either the Palau Trench or the Sorong Fault, but there are numerous earthquake epicentres reported between the southern end of the trench and the Molucca Sea. The island of Halmahera is considered to lie in a diffuse boundary zone at the margin of the Philippine Sea Plate. Continued collision of the opposing arcs in the Molucca Sea will ultimately prevent further E-W convergence between Halmahera and Sulawesi. It is predicted that either the Philippine Trench will propagate south along

    The GEF/UNDP/IMO/PEMSEA project identifies Manila Bay as among the marine pollution hot spots in the Seas of East Asia. (210)Pb dating of its sediment can provide a historical perspective of its pollution loading. However, the validity of (210)Pb dating in a complex dynamic coastal system of Manila Bay may come into question. Land-based sediment input can be high and physical and biological processes can possibly disturb the sediment layers. In this report, the (210)Pb profiles of sediment cores from different parts of the bay are presented. The linear sedimentation rates are shown to be higher in the recent past and are also variable across the bay. The largest change in sedimentation rate, coincided with the occurrence of a volcanic eruption in 1991 and is shown by applying a variant of the CIC model in sedimentation rate calculations. The data suggest that (210)Pb dating can be useful in estimating relative magnitudes of sedimentation rates, even in a complex dynamic coastal system like Manila Bay.

    Manila clam (Ruditapes philippinarum) is a valuable and intensively exploited shellfish species in Korea. Despite its importance, information on its genetic background is scarce. For the genetic characterization of R. philippinarum, expressed sequence tag-derived microsatellite markers were developed using next-generation sequencing. A total of 5879 tandem repeats containing di- to hexanucleotide repeat motifs were obtained from 236,746 reads (mean = 413 bp). Of the 62 loci screened, 24 (38.7%) were successfully amplified, and 10 were polymorphic in 144 individuals from 2 manila clam populations (Incheon and Geoje, Korea). The number of alleles ranged from 2 to 17 in the Incheon population and from 3 to 13 in the Geoje population (overall AR = 7.21). The mean observed and expected heterozygosities were estimated to be 0.402 and 0.555, respectively. Hence, there is less genetic variability in the Geoje population than in the Incheon population, although no significant reductions of genetic diversity were found between the populations (P > 0.05). However, significant genetic differentiation was detected between the populations (FST = 0.064, P < 0.001). Significant deviations from Hardy-Weinberg equilibrium and high inbreeding coefficients (mean FIS = 0.22-0.26) were detected in both populations. The 10 novel polymorphic microsatellite loci used in this study will be useful for future genetic mapping studies and for characterizing population structures, monitoring genetic diversity for successful aquaculture management, and developing conservation strategies for manila clam populations in Korea.

    The Philippines has experienced rapid sociodemographic changes in recent years, with implications for adolescents. This study combines quantitative and qualitative data from Metro Cebu to assess the timing and predictors of adolescent partnerships, as well as the context in which these partnerships are occurring. The majority of adolescents (54%) had premarital sex, though this pattern varied by gender. Wealthier, urban men, and women with less education and lower reported religiosity, were more likely to have premarital sex. Engagement in risk behaviors was predictive of premarital sex for both males and females. The qualitative data contextualize the circumstances under which adolescents engage in sex and form partnerships, and illustrate how sociocultural norms contribute to gender differences in partnership patterns. Given the ‘new’ realities of young Filipinos’ lives, targeted efforts to support adolescents’ transition to adulthood are needed to avert potentially adverse lifeevents. PMID:22587636

    Setting: Socio-economically underprivileged urban areas in the Philippines. Objectives: To identify gaps in the referral pathway of presumptive drug-resistant tuberculosis (DR-TB) patients from initial consultation until initiation of treatment. Design: A retrospective study in which a masterlist of presumptive multidrug-resistant TB (MDR-TB) patients registered in 18 DOTS facilities in Tondo, Manila and Payatas, Quezon City, from October 2012 to September 2013, was analysed and reviewed. Results: Among 378 presumptive DR-TB patients identified and listed in the masterlist, 97% (368/378) were referred, of whom 90% (333/368) were screened at an MDR-TB treatment centre. Of the 368 patients, 35 (9.5%) were not screened, mainly due to loss to follow-up. Among those screened, 86.4% (288/333) were recommended for anti-tuberculosis treatment, of whom 98.2% (283/288) initiated treatment. The time between sample collection and examination was significantly longer at the laboratories of non-government organisations (NGOs) than at local government units (LGUs) (1 day vs. 0 day; P < 0.001). The time to the release of smear examination results to patients was significantly shorter at the NGOs than at the LGUs (4 days vs. 6 days; P = 0.009). Conclusion: The development of the presumptive MDR-TB masterlist facilitated tracking of patients for diagnosis and treatment. The NGOs should reduce delays in diagnosis and the LGUs should intensify patient follow-up to ensure early initiation of treatment. PMID:28123960

  1. Population pressure and migration: implications for upland development in the Philippines.

    1988-01-01

    The identification of Philippine upland sites using topographic maps and photographs, the estimation of population from the 1980 census, and the verification of major migration streams was carried out. The upland population numbered 14.4 million persons according to the 1980 Census. After 1948 up to 1960 the movement of people from the Visayas regions to the frontier lands of Mindanao occurred. The 2nd wave of predominantly urbanward migration occurred after 1960, although in the early 1970s some 47,000 migrants moved to the uplands from Metropolitan Manila. The early-period migrants tended to be young males between 20 and 34 years of age. Migrants tended to be 45-54 years old in the period after 1960. The results of 3 macro-migration econometric models indicated that the availability of land in the uplands was the decisive determinant of movement, and in the long distance interregional flows, the actual length of distance traveled emerged as significant. Factors such as population and education at the areas of destination were significant for the shorter, interprovincial flows. At the municipality level land-related variables were more significant than demographic factors. The factors of distance and demographic size accounted for the large variability in migration. 3 villages in the Mount Makiling watershed were used to evaluate circumstances of movement, frequency, and mode of travel, and the socioeconomic correlates such as income, occupation, ownership status, and education. The average age of migrants was 26 years, about 1/2 of them were married, and the rest were single males in 1960-1970. According to a multiple regression model the determinants of migrant incomes were: 1) acquisition of lands of good quality, 2) access to credit for purchase of inputs, 3) increased commercialization of farming activities, 4) promotion of diversified cropping patterns, and 5) planting of perennials.

    Observing changes in the composition and discharge rates of volcanic gases is an important part of volcanic monitoring programs, because some gases released by progressive depressurization of magma during ascent are highly mobile and reach the surface well before their parental magma. Among volcanic gases, CO2 is widely used in volcano studies and monitoring because it is one of the earliest released gas species from ascending magma, and it is considered conservative. Taal Volcano in Southwest Luzon, Philippines, lies between a volcanic arc front (facing the subduction zone along the Manila Trench) and a volcanic field formed from extension beyond the arc front. Taal Volcano Island is formed by a main tuff cone surrounded by several smaller tuff cones, tuff rings and scoria cones. This island is located in the center of the 30 km wide Taal Caldera, now filled by Taal Lake. To monitor the volcanic activity of Taal volcano is a priority task in the Philippines, because several million people live within a 20-km radius of Taal's caldera rim. In the period from 2010-2011, during a period of volcanic unrest, the main crater lake of Taal volcano released the highest diffuse CO2 emission rates reported to date by volcanic lakes worldwide. The maximum CO2 emission rate measured in the study period occurred two months before the strongest seismic activity recorded during the unrest period (Arpa et al., 2013, Bull Volcanol 75:747). In the light of the excellent results obtained through diffuse degassing studies, an automatic geochemical station to monitor in a continuous mode the diffuse CO2 degassing in a selected location of Taal, was installed in January 2016 to improve the early warning system at the volcano. The station is located at Daang Kastila, at the northern portion of the main crater rim. It measures hourly the diffuse CO2 efflux, atmospheric CO2 concentration, soil water content and temperature, wind speed and direction, air temperature and humidity, rainfall

During the last period of volcanic unrest from 2010 to 2011, the main crater lake of Taal volcano released the highest diffuse CO2 emission rates through the water surface reported to date by volcanic lakes worldwide. The maximum CO2 emission rate measured in the study period occurred two months before the strongest seismic activity recorded during the unrest period (Arpa et al., 2013, Bull Volcanol 75:747). After the unrest period, diffuse CO2 emission has remained in the range 532-860 t/d in the period 2013-2016.

    Bathymetric map of SCS plate shows two subducting buoyancies, the fossil ridge and the oceanic plateau, which are supposed to impact slab segmentation into the north from Taiwan to 18°N, and the south from 17°N to Mindoro. Hypocenter distribution show that slab dip angle turns lower southwards from 45° to 30° in the north segment, and relatively equals ~45° in the south segment at the depth of 100km. Moreover, volcano distribution can be segmented into Miocene WVC, Quaternary EVC in the north and combined SVC in the south (Fig. A). We found that WVC and SVC mostly locate in a parallel belt ~50km apart to Manila trench, however EVC turn father southwards from 50km to 100km (Fig. B). Above characters congruously indicate that SCS plate kept equal dip angle in Miocene; then the north segment shallowed at 18°N and developed northwards in Quaternary, resulting in lower dip angle than the invariant south segment. To check the transformation of slab dip angle from 45° to 30° between 17~18°N, focal mechanism solution nearby 17°N are found 90° in rake and dip angle, strike parallel to the fossil ridge, indicating a slab tear located coincident with the ridge, where is a weak zone of higher heat flow and lower plate coupling ratio than the adjacent zones and slab can be easily tore as an interface for SCS plate segmentation. Subduction of the two buoyancies within SCS plate is supposed as influential dynamic factor: It caused the trench retreat rate reduced, forming a cusp and a flat convex of Manila trench shape; Moreover, the buoyancies resisted subduction, resulting in shear stress heterogeneity of SCS plate, in consequence the fossil ridge as a fragile belt potentially became stress concentration zone that easily tore; Then the buoyant oceanic plateau might lead to shallowing of the northern SCS plate. To examine the hypothesis, dynamic effects of the two subducting buoyancies are being respectively investigated based on numerical models. (Grt. 41376063, 2013

    Agricultural lands near Manila, Utah, have been identified as contributing dissolved solids to Flaming Gorge Reservoir. Concentrations of dissolved solids in water resources of agricultural lands near Manila, Utah, ranged from 35 to 7,410 milligrams per liter. The dissolved-solids load in seeps and drains in the study area that discharge to Flaming Gorge Reservoir ranged from less than 0.1 to 113 tons per day. The most substantial source of dissolved solids discharging from the study area to the reservoir was Birch Spring Draw. The mean daily dissolved-solids load near the mouth of Birch Spring Draw was 65 tons per day.The estimated annual dissolved-solids load imported to the study area by Sheep Creek and Peoples Canals is 1,330 and 13,200 tons, respectively. Daily dissolved-solid loads discharging to the reservoir from the study area, less the amount of dissolved solids imported by canals, for the period July 1, 2004, to June 30, 2005, ranged from 72 to 241 tons per day with a mean of 110 tons per day. The estimated annual dissolved-solids load discharging to the reservoir from the study area, less the amount of dissolved solids imported by canals, for the same period was 40,200 tons. Of this 40,200 tons of dissolved solids, about 9,000 tons may be from a regional source that is not associated with agricultural activities. The salt-loading factor is 3,670 milligrams per liter or about 5.0 tons of dissolved solids per acre-foot of deep percolation in Lucerne Valley and 1,620 milligrams per liter or 2.2 tons per acre-foot in South Valley.The variation of δ87Sr with strontium concentration indicates some general patterns that help to define a conceptual model of the processes affecting the concentration of strontium and the δ87Sr isotopic ratio in area waters. As excess irrigation water percolates through soils derived from Mancos Shale, the δ87Sr isotopic ratio (0.21 to 0.69 permil) approaches one that is typical of deep percolation from irrigation on Mancos

    Philippine migration policy is traced from the early 1970s to the present. The main migration trends in the 1990s are described. An assessment is made of the efficacy and appropriateness of present migration policy in light of the economic crisis. A regional approach to migration policy is necessary in order to encourage placing migration as a greater priority on national agendas and in bilateral agreements. In the Philippines, migrants are considered better paid workers, which diminishes their importance as a legislative or program priority. Santo Tomas (1998) conducted an empirical assessment of migration policies in the Philippines, but refinement is needed. Although migration is a transnational experience, there is little dialogue and cooperation among countries. Philippine migration policy defines its role as an information resource for migrants. Policy shifted from labor export to migrant management in the public and private sectors. Predeparture information program studies are recommending a multi-stage process that would involve all appropriate parties. There is talk of including migration information in the education curriculum. There are a variety of agendas, competing interests, and information resources between migration networks and officiating agencies. The Asian financial crisis may have a mild impact, but there are still issues of reintegration, protection, and employment conditions

    2017-02-21

    The Philippines is a low middle-income, tropical country in Southeast Asia. Infectious diseases remain the main causes of morbidity, including tuberculosis. AIDS/HIV prevalence is still low at <1%, but is rapidly increasing. Fungal disease surveillance has not been done, and its burden has never been estimated. This becomes more important as the population of immunocompromised patients increases, drawn from patients with AIDS, TB, malignancies, and autoimmune diseases requiring chronic steroid use. Using the methodology of the LIFE program ( www.LIFE-worldwide.org ), estimates were derived from data gathered from WHO, UNAIDS, Philippine Health Statistics 2011, Philippine Dermatological Society Health Information System database, HIV/AIDS and ART registry of the Philippines, epidemiological studies such as The TREAT Asia HIV Observational Database 2005, and personal communication. Aspergillosis and candidiasis were the top causes of fungal infections in the Philippines. Chronic pulmonary aspergillosis (CPA), drawn from the number of tuberculosis patients, affects 77,172 people. Allergic bronchopulmonary aspergillosis (ABPA) and severe asthma with fungal sensitization (SAFS) frequencies, which were derived from the number of asthmatic patients, affect 121,113 and 159,869 respectively. Recurrent vulvovaginal candidiasis (RVVC) affects 1,481,899 women. Other estimates were cryptococcal meningitis 84, Pneumocystis pneumonia 391, oral candidiasis 3,467, esophageal candidiasis 1,522 (all in HIV-infected people), invasive aspergillosis (IA) 3,085, candidemia 1,968, candida peritonitis 246, mucormycosis 20, fungal keratitis 358, tinea capitis 846 and mycetoma 97 annually. A total of 1,852,137 (1.9% of population) are afflicted with a serious fungal infection. Epidemiological studies are needed to validate these estimates, facilitating appropriate medical care of patients and proper prioritization of limited resources.

  6. Public higher education in the Philippines

    Clearly, the national government of the Philippines has decided to increase the number and comprehensiveness of its public colleges and universities. While private colleges and universities are likely to dominate higher education in the Philippines for the remainer of this century, it appears that public, tax-supported higher education will become increasingly available there. The Philippines is not a wealthy country but it is devoting a substantial portion of its national resources to public higher education. In 1983, higher education received 2.85 percent of the national budget, a figure that has been rising for years. Compared with some highly developed countries, this is not a large percentage, but for a country that has traditionally relied on private higher education, it is a major and growing investment in the public sector. While many of the better universities in the Philippines are private, many other private educational institutions are small and struggling. As their financial resources become more limited, and as less expensive, tax-supported higher education becomes increasingly available, a lot of the struggling private colleges will probably close. This process is also being hastened by actions of the government to upgrade quality, for example in the case of the many private colleges that developed after World War II. In an attempt to improve the academic quality of these marginal institutions, the Ministry of Education, Culture and Sports has been given extensive authority, and while its intrusion into private institutions has been modest by some measures, its requirements are affecting them all and will speed the demise of some. This is bound to lead to a stronger role for public higher education in the Philippines, a country that is striving diligently to improve the education and hence the quality of life of its people.

    Polyphenol oxidase (PPO) is an enzyme widely distributed in the plant kingdom that has been detected in most fruits and vegetables. PPO was extracted and purified from Manila mango (Mangifera indica), and its biochemical properties were studied. PPO was purified 216-fold by hydrophobic interaction and ion exchange chromatography. PPO was purified to homogeneity, and the estimated PPO molecular weight (MW) by SDS-PAGE was ≈31.5 kDa. However, a MW of 65 kDa was determined by gel filtration, indicating a dimeric structure for the native PPO. The isolated PPO showed the highest affinity to pyrogallol (Km = 2.77 mM) followed by 4-methylcatechol (Km = 3.14 mM) and catechol (Km = 15.14 mM). The optimum pH for activity was 6.0. PPO was stable in the temperature range of 20-70 °C. PPO activity was completely inhibited by tropolone, ascorbic acid, sodium metabisulfite, and kojic acid at 0.1 mM.

    Bioaccumulation of radiocaesium in many marine organisms occurs through complex trophic transfer mechanisms. The present study addresses the trophic transfer of (134)Cs in the widely distributed marine bivalve, the Manila clam Ruditapes philippinarum, by experimentally determining the assimilation efficiency (AE) and the specific role of food quality or diet on the AE in this marine invertebrate. Pulse-chase feeding experiments were carried out on this clam using the phytoplankton species Tetraselmis chuii, Phaeodactylum tricornutum and Isochrysis galbana. Depuration kinetics of (134)Cs over 21 days were analysed using a two-component exponential model. Observed assimilation efficiencies were consistently less than 10% but slightly varied among individuals fed on the three different phytoplankton species diets (T. chuii: AE = 8.4 ± 0.6%; P. tricornutum: AE = 9.8 ± 0.5%; I. galbana: AE = 5.3 ± 0.6%), although no statistical differences were observed. Comparing results from these experiments with existing data from the literature on the same species exposed to caesium through seawater, it appears that trophic transfer processes are the main accumulation pathway, contributing up to 96% of the global (134)Cs bioaccumulation in this bivalve species.

    This paper assesses the impact of tsunamis in the East Vietnam Sea potentially originated from a giant rupture along the Manila Trench to the Vietnamese coast. Tsunami heights and arrival times to the major forecast points along the Vietnamese coast are computed using COMCOT model. The results of the worst case scenario (Mw = 9.3) and two extreme scenarios were used to assess the tsunami hazards. The simulation results show that Vietnamese coast can be divided into three parts with different levels of tsunami hazard. The highest threat exists along the coasts of Central and North-Central Vietnam, from Quang Binh to Ba Ria - Vung Tau provinces, with maximum wave height of 18 m observed near Quang Ngai coast, and a tsunami would reach this coastline in two hours at the earliest. The northern coastal zone of Vietnam has lower tsunami hazard. In the worst case scenario, maximum amplitudes of tsunami waves at Hai Phong sea port and Nam Dinh city, North Vietnam, are 3.5 m and 3.7 m, respectively, while the travel times to these sites are much longer, over 8 h. The southern coastal zone of Vietnam has very low tsunami hazard. In the worst case scenario, the maximum amplitude at Ca Mau is 0.12 m, while the travel time is over 10 h.

    Manila clams (Ruditapes philippinarum) and sediments were collected bimonthly during 2007 at five locations in Jiaozhou Bay near Qingdao, China, to determine heavy metal concentrations and to assess the validation of R. philippinarum as a metal biomonitor. Concentrations of heavy metals in clam soft tissues ranged between 0.75 and 3.31, 0.89 and 15.20, 5.70 and 26.03, 52.12 and 110.33, 10.30 and 72.34, 9.64 and 28.60, and 3.15 and 52.75 μg g(-1) dry weight for Cd, Pb, Cu, Zn, Mn, Cr, and Ni, respectively. Most of the highest values occurred at the northeast bay and the lowest values occurred at the western part. Regarding seasonal variation, relatively high tissue metal concentrations were observed during October or December. A similar pattern was also found in habitat sediments. There was a strong correlation between the concentrations of Cd, Pb, Zn, Mn, Cr, and Ni in soft tissues and surrounding sediments. It is indicated that R. philippinarum could be used as a biomonitor for heavy metal contamination in Jiaozhou Bay.

    Manila mangoes (Mangifera indica L.) have sensory characteristics that make them attractive for consumption as a fresh fruit. A large portion of the annual yield of this fruit is infested by the Mexican fruit fly (Anastrepha ludens), adversely impacting the quality of the crop. Hence, it is necessary to develop economically viable postharvest treatments to reduce the damage caused by this insect. Currently, high hydrostatic pressures are used to guarantee the safety of many processed foods. The objective of this work was to assess the effects of high hydrostatic pressure on mangoes at their physiological maturity. High hydrostatic pressures were applied to mangoes at three levels: 50, 100 and 200 megapascals applied for four different time periods (0, 5, 10 and 20 min). Physiologically mature mangoes were more resistant to changes in response to the pressure of 50 MPa. Reduction of physiological activity by application of high hydrostatic pressure opens a new avenue for the research on treatments intended to enhance preservation of whole fresh fruit.

    Redspotted grouper nervous necrosis virus (RGNNV), genus Betanodavirus, family Nodaviridae, is the causative agent of viral encephalopathy and retinopathy (otherwise known as viral nervous necrosis) and can infect several fish species worldwide. Betanodaviruses, including RGNNV, are very resilient in the aquatic environment, and their presence has already been reported in several wild marine species including invertebrates. In order to investigate the interaction between a bivalve mollusc (Manila clam Ruditapes philippinarum) and RGNNV, we optimised a culture-based method. The bioaccumulation of the pathogenic RGNNV by R. philippinarum and the potential shedding of viable RGNNV from RGNNV-exposed clams were evaluated through a culture-based method. R. philippinarum clearly accumulated viable RGNNV in their hepatopancreatic tissue and were able to release viable RGNNV via faecal matter and filtered water into the surrounding environment. The role of clams as bioaccumulators and shedders of viable RGGNV could put susceptible cohabiting cultured fish at risk. RGNNV-contaminated molluscs could behave as reservoirs for this virus and may modify the virus epidemiology.

  15. Air quality inside subway metro indoor environment worldwide: A review.

    PubMed

    Xu, Bin; Hao, Jinliang

    2017-10-01

    The air quality in the subway metro indoor microenvironment has been of particular public concern. With specific reference to the growing demand of green transportation and sustainable development, subway metro systems have been rapidly developed worldwide in last decades. The number of metro commuters has continuously increased over recent years in metropolitan cities. In some cities, metro system has become the primary public transportation mode. Although commuters typically spend only 30-40min in metros, the air pollutants emitted from various interior components of metro system as well as air pollutants carried by ventilation supply air are significant sources of harmful air pollutants that could lead to unhealthy human exposure. Commuters' exposure to various air pollutants in metro carriages may cause perceivable health risk as reported by many environmental health studies. This review summarizes significant findings in the literature on air quality inside metro indoor environment, including pollutant concentration levels, chemical species, related sources and health risk assessment. More than 160 relevant studies performed across over 20 countries were carefully reviewed. These comprised more than 2000 individual measurement trips. Particulate matters, aromatic hydrocarbons, carbonyls and airborne bacteria have been identified as the primary air pollutants inside metro system. On this basis, future work could focus on investigating the chronic health risks of exposure to various air pollutants other than PM, and/or further developing advanced air purification unit to improve metro in-station air quality.

    Digital coherent technology is considered an attractive way of realizing both high-speed metro links and long distance transmissions. In metro areas, there is a strong demand for a smaller, faster transceiver module. This demand is mainly driven by the rapidly increasing data center interconnection traffic, where transmission capacity per faceplane is a key feature. Therefore, optical integration technology is desired. Since compensation in digital coherent technology is performed in the electrical or digital domain, users can deal with those optics performances that are not compensated for digitally. This means using a new material that cannot provide perfect characteristics but that is suitable for miniaturization and integration is possible. Silicon photonics (SiPh) is considered an attractive technology that would enable the significant miniaturization of optical circuits and be capable of optical integration with high manufacturability. While SiPh-based devices have begun to be deployed for very short or short reach links on the basis of direct detection technology, their digital coherent applications have recently been investigated in view of their integration capability. This paper describes recent progress on SiPh-based integrated optical devices for high-speed digital coherent transceivers targeting metro links. An optical modulator and receiver with related circuits have been integrated into a single SiPh chip. TEC-free operation under non-hermetic conditions and the direct attachment of optical fibers have both been realized. Very thin and small packaging with sufficient performance has been demonstrated by using the SiPh chip co-packaged with high-speed ICs.

    This study investigated the internal osmotic regulatory capabilities of the Manila clam (Ruditapes philippinarum) following in vivo exposure to a range of salinities. A second objective was to measure the health status of the Manila clam following exposure to different salinities using the neutral red retention (NRR) assay, and to compare results using a range of physiological saline solutions (PSS). On exposure to seawater of differing salinities, the Manila clam followed a pattern of an osmoconformer, although they seemed to partially regulate their circulatory haemolytic fluids to be hyperosmotic to the surrounding aqueous environment. Significant differences were found when different PSS were used, emphasizing the importance of using a suitable PSS to reduce additional osmotic stress. Using PSS in the NRR assay that do not exert additional damage to lysosomal membrane integrity will help to more accurately quantify the effects of exposure to pollutants on the organism(s) under investigation.

    Mindoro Island has been proposed to be the product of ancient arc-continent collision between the Palawan microcontinental block at the Eurasian plate and the Philippine mobile belt. This island is also a transition zone from subduction along the Manila trench to a strike slip fault system. Abundant earthquakes are clustered in the northern Mindoro belonging to the Manila subduction system while seldom earthquakes are discovered in central and southern island. However, the mechanism of transition from subduction to strike slip in Mindoro Island is still unclear. In order to comprehend the characteristics of crustal deformation in the island, 8 continuous GPS observations from 2010 to 2015 and multitrack ALOS/PALSAR images from 2007 to 2011 are adopted in this area. In this study, we use the Bernese software v.5.0 to process the GPS data and the Stanford Method for Persistent Scatterers (StaMPS) for PSInSAR. The GPS horizontal velocity field relative to the station JOSE under ITRF2014 indicates that the relative motion changes northward from NNW-trend at rates of 3 mm/yr in southern island to WNW-trend at rates of 30 mm/yr in northern island. It also shows an apparent counterclockwise rotation causing by the collision-induced rotation. The averaging rotation rate is about 10.5° ± 2.4°/Myr derived from the asymmetric portion of the velocity gradient tensor. The major velocity difference ( 27 mm/yr) between the northern and southern island indicates an internal strain results from the motion of unknow structures in Mindoro. The northern island was mainly characterized by a WNW-ESE extension at a rate of 180 nstrain/yr while the southern Island shows strike slip type at a rate of 5 nstrain/yr. The line of sight (LOS) velocity field from PSInSAR shows that the differences of velocity ( 10 mm/yr) in the southern island are parallel to the NNW-SSE trend of the central mountain range which may be the locations of left-lateral strike-slip fault system. Following, we will

    1995-06-01

    The Philippine electricity industry has shown it can change, and change quickly. In contrast with the crises and changes imposed on it in the past, the industry now has as opportunity to forge a progressive, forward-looking strategy, This opportunity is enhanced by the force of law - the Department of Energy Act of 1992 mandates privatization of the National Power Corporation (NPC) - and by the easing of the power crisis which has significantly diminished political interference. In order to position the industry for growth and rising investment requirements and to support the growing role of the Philippine economy in international markets, that strategy must address the structural deficiencies that continue to plague the industry. By addressing structural changes that need to be made now, it can build on the impetus gained from its privatization mandate to improve accountability, increase efficiency and reduce government risk.

    Developed countries facing nursing shortages have increasingly turned to aggressive foreign nurse recruitment, primarily from developing nations, to offset their lagging domestic nurse supplies and meet growing health care demands. Few donor nations are prepared to manage the loss of their nurse workforce to migration. The sole country with an explicit nurse export policy and the world's leading donor of nurse labor - the Philippines - is itself facing serious provider maldistribution and countrywide health disparities. Examining the historical roots of Philippines nurse migration provides lessons from which other nurse exporting countries may learn. The authors discuss factors that have predicated nurse migration and policies that have eased the way. Furthermore, the authors analyze how various stakeholders influence migratory patterns, the implications of migration for nurses and the public in their care, and the challenges that future social policy and political systems face in addressing global health issues engendered by unfettered recruitment of nurses and other health workers.

    Purpose This study aimed to assess the appropriateness of the International Classification for Nursing Practice (ICNP) Palliative Care for Dignified Dying catalogue for palliative nursing in the Philippines. Methods The study recruited 230 nurses to complete the ICNP Dignified Dying survey. Participants rated ICNP nursing intervention items and identified additional interventions for promoting dignified dying. Results All of the intervention items were scored on average as being at least ‘slightly important’. The three top-ranked nursing intervention categories were providing social support, maintaining privacy boundaries, and relieving psychological distress. Conclusions The ICNP Palliative Care for Dignified Dying catalogue lists nursing interventions that are appropriate to promoting dignity at the end of life in the Philippines. PMID:21471908

  8. Post Eruption Hazards at Mt. Pinatubo, Philippines

    Our project focused on the investigation of the post-eruption hazards at Mt. Pinatubo (Philippines) using remote sensing data, and field observations of the 1991 eruption deposits. Through the use of multiple satellite images, field work, and the 1996/2000 PacRim data sets, we conducted studies of the co- and post-eruption hazards of the volcano due to erosion and re-deposition of the extensive pyroclastic flow deposits. A major part of this project was the assembly and analysis of a database of over 50 high resolution (1 - 50 m/pixel) images that will facilitate this study. We collected Ikonos, SPOT, SIR-C/X-SAR, Landsat, ERS, RADARSAT, and ASTER images of the area around Mt. Pinatubo. An example of the changes that could be seen in these data is shown. Our investigation focused on a retrospective analysis of the erosion, redeposition, and re-vegetation of the 1991 pyroclastic flow deposits of Mt. Pinatubo. The primary geologic goal of our work was the analysis of the spatial distribution and volume change of the sources and sinks of materials associated with mudflow ('lahar') events. This included the measurement of river valley gradients and cross-sections using TOPSAR digital elevation data, as we are participating in the PacRim 2000 deployment to the Philippines specifically so that we can collect a second set of TOPSAR data that can then be used to create a topographic difference image of the volcano. The main results from this multi-sensor study have been published as Torres et al.. A discussion of the methodology that we used to assemble an appropriate database was included in Mouginis-Mark and Domergue-Schmidt. As part of an educational outreach effort, we also helped the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in the Philippines to use NASA data to study Mt. Pinatubo and other Filipino volcanoes.

  9. Accreditation of clinical laboratories in the Philippines.

    PubMed

    Maramba, T P

    2002-01-01

    In order to assure the reliability of the results of laboratory services, clinical laboratories are regulated in the Philippines. This started with the passage of the Clinical Laboratory Law in 1965, which required the Licensing of clinical laboratories by the Bureau of Research and Laboratories, Department of Health (BRL, DOH) before they can operate. Standards were set for the various types of laboratory services. In 1988, the minimum standards of laboratory services were formulated for three categories, ie, primary, secondary and tertiary categories. Subsequently, to permit clinical laboratories to offer 'special service', accreditation of clinical laboratories was instituted. In 1968, the Philippine Society of Pathologists (PSP) decided to accredit clinical laboratories for Residency Training Program in Anatomic and Clinical Pathology. The following year after the passage of the Medical Technology Law, the BRL, DOH began accrediting clinical laboratories that trained Medical Technology Interns. A few years later, the BRL, DOH started to accredit clinical laboratories who did Water Analysis. In 1989, after realizing the serious implications of HIV Testing, the DOH mandated the BRL, DOH to set standards for clinical laboratories performing HIV testing. In 1997, upon request of the Philippine Health Insurance Corporation (PhilHealth), the PSP formulated and submitted standards for the accreditation of clinical laboratories, both hospital and free-standing, for reimbursement of fees for laboratory services rendered to patients enrolled in the PhilHealth social insurance program. In 2000, the Philippine Council for Accreditation of Healthcare Organizations (PCAHO) approved the Standards for the accreditation of Hospitals for the provision of quality medical services. Included were the standards for the Department of Pathology.

    Rehabilitation in the Philippines has in the past been based on the Western model, with an emphasis on hospital departments located in the major cities. This approach is inappropriate for the majority of disabled people in the Republic as 70% of the population live in rural areas. A community-based programme was devised using local volunteers who had simple training. These volunteers can identify and support disabled people in their own villages, avoiding long journeys and expensive institutional care.

    Salmonella enterica is a well-known pathogen commonly acquired from the consumption of contaminated food. It has been estimated to affect millions of humans and cause hundreds of thousands of deaths per year globally. Pork, one of the most commonly consumed meats worldwide, has been identified as one of the main sources of human salmonellosis. In this study, we aimed to detect and characterize S. enterica from slaughtered swine and generate antimicrobial resistance profiles of select isolates. Tonsils and jejunum with mesenteric lymph nodes (MLN) were collected from a total of 240 swine from eight abattoirs (five accredited and three locally registered abattoirs) across Metro Manila. S. enterica were isolated using conventional culture methods and confirmed by PCR amplification of the invA gene. Isolates were further characterized based on somatic antigen by multiplex PCR. We report that there is no significant difference (P = 0.42) between the incidences of S. enterica in swine slaughtered in accredited (44.0%) and in locally registered abattoirs (46.7%). Most samples were contaminated with S. enterica under serogroup O:3,10. Antimicrobial susceptibility testing of 183 isolates using the VITEK(®) 2 system revealed high resistance to ampicillin (67.8%) and trimethoprim/sulfamethoxazole (80.3%). Multidrug-resistance was found in 124 (67.8%) isolates. Copyright © 2017 Elsevier Ltd. All rights reserved.

  17. Photovoltaic battery charging experience in the Philippines

    With the turn of the century, people in remote areas still live without electricity. Conventional electrification will hardly reach the remaining 50% of the population of the Philippines in remote areas. With photovoltaic technology, the delivery of electricity to remote areas can be sustainable. Malalison island was chosen as a project site for electrification using photovoltaic technology. With the fragile balance of ecology and seasonal income in this island, the PV electrification proved to be a better option than conventional fossil based electrification. The Solar Battery Charging Station (SBCS) was used to suit the economic and geographical condition of the island. Results showed that the system can charge as many as three batteries in a day for an average fee of $0.54 per battery. Charging is measured by an ampere-hour counter to determine the exact amount of charge the battery received. The system was highly accepted by the local residents and the demand easily outgrew the system within four months. A technical, economic and social evaluation was done. A recovery period of seven years and five months is expected when competed with the conventional battery charging in the mainland. The technical, economic, institutional and social risks faced by the project were analyzed. Statistics showed that there is a potential of 920,000 households that can benefit from PV electrification in the Philippines. The data and experiences gained in this study are valuable in designing SBCS for remote unelectrified communities in the Philippines and other developing countries.

  18. Challenges of Space Education in the Philippines

    Sese, Rogel Mari

    The Philippines has recently started in developing and promoting space science education through the Philippine Space Science Education Program (PSSEP) of the Department of Science and Technology (DOST). However, as a developing country, there are numerous challenges in promoting space education to students and teachers. In this paper, we assessed the recent activities done by the PSSEP and demonstrate their effectiveness. In addition, we will expound on the social, political and logistical challenges of promoting space education in an archipelago such as the Philippines. We will also present the preliminary feedback and assessment of the Space Science Program (SSP), a pilot program which teaches space science as a separate subject in the basic educational system from kindergarten to high school. We will also discuss the various teaching strategies we utilized in the SSP that can be adopted depending on the needs and capabilities of the host school. Finally, we discuss the challenges of instituting a formal astronomy and space science course and the issues that needs to be addressed for an effective and sustainable program.

  19. Transcriptional changes in Manila clam (Ruditapes philippinarum) in response to Brown Ring Disease.

    Brown Ring Disease (BRD) is a bacterial infection affecting the economically-important clam Ruditapes philippinarum. The disease is caused by a bacterium, Vibrio tapetis, that colonizes the edge of the mantle, altering the biomineralization process and normal shell growth. Altered organic shell matrices accumulate on the inner face of the shell leading to the formation of the typical brown ring in the extrapallial space (between the mantle and the shell). Even though structural and functional changes have been described in solid (mantle) and fluid (hemolymph and extrapallial fluids) tissues from infected clams, the underlying molecular alterations and responses remain largely unknown. This study was designed to gather information on clam molecular responses to the disease and to compare focal responses at the site of the infection (mantle and extrapallial fluid) with systemic (hemolymph) responses. To do so, we designed and produced a Manila clam expression oligoarray (15K Agilent) using transcriptomic data available in public databases and used this platform to comparatively assess transcriptomic changes in mantle, hemolymph and extrapallial fluid of infected clams. Results showed significant regulation in diseased clams of molecules involved in pathogen recognition (e.g. lectins, C1q domain-containing proteins) and killing (defensin), apoptosis regulation (death-associated protein, bcl-2) and in biomineralization (shell matrix proteins, perlucin, galaxin, chitin- and calcium-binding proteins). While most changes in response to the disease were tissue-specific, systemic alterations included co-regulation in all 3 tested tissues of molecules involved in microbe recognition and killing (complement-related factors, defensin). These results provide a first glance at molecular alterations and responses caused by BRD and identify targets for future functional investigations.

    Background: The research productivity of a place depends on doctors, patients and available infrastructure to carry research activities. Aims: We aimed to study the publishing trends and research productivity of metro and non-metro cities in the Journal of the Association of Physi cians of India (JAPI). Materials and Methods: Bibliometric analysis of research articles published in JAPI between 2000 and 2011was undertaken. The four types of articles (original articles including brief reports, case reports, correspondence and pictorial image) were studied for research productivity. They were analyzed according to subspecialty, publication times and type of research work from both places. Comparison between groups was done using Fisher exact and Mann-Whitney U test. Descriptive statistics were used and a P < 0.05 was considered significant. Results: Of a total of 2977 articles, 1798 were available for analysis. Metros published 46% (825/1798) and non-metros 54% (973/1798). Original articles and case reports constituted 3/4th of the published literature from both places. Pictorial images were seen more from non-metro cities (P = 0.03). Mumbai and Delhi were leading from the metros, whereas Varanasi and Chandigarh were leading from the non-metro places. Endocrinology, Neurology, Cardiology and Infectious Diseases constituted the top four subspecialties from both places. Neurology articles were published more from non-metros (P = 0.03). The timelines from submission to publication varied between 12 and 15 months, and were lesser for articles from the metros (P = 0.01). Conclusions: Metros and non-metro cities are comparable in publishing trends and research productivity. Places with post-graduate institutes contribute majority of the research articles. Faster publication timelines from metros indicate better manuscript content and preparation. PMID:23919186

    Following the amalgamation of a collage of pre-Neogene terranes largely by strike-slip and convergence mechanisms to form the Philippine islands, volcanic chains, related to oppositely dipping subduction zones, developed along the eastern and western margins of the archipelago. There is ample field evidence that this volcanic activity, predominantly calc-alkaline in chemical character, had commenced by the Oligocene. Volcanoes resulting from subduction along the Manila-Negros trench in the west (e.g. Taal, Laguna de Bay and Arayat) form a high-angle linear array, trending away from the MORE field on Pb-isotopic covariation diagrams; have the highest Sr- and lowest Nd-isotopic compositions, of the two chains (but nevertheless plotting above bulk earth on the 87Sr/86Sr versus 143Nd/144Nd covariation diagram); and exhibit Sm/Nd and Rb/Sr values that are lower and higher, respectively, than the estimated values for bulk earth. While the Sm/Nd and Rb/Sr characteristics are common to both chains, volcanoes associated with the Philippine-East Luzon trench have Pb-isotopic compositions that fall in the Indian Ocean MORB field and that require time-integrated evolution in a high Th/U environment. They also have higher Nd- and lower Sr-isotopic ratios. The source materials of Philippine volcanoes, therefore, have undergone varied recent enrichments in LILE, as indicated by the decoupling of isotopic and elemental ratios. These enrichments, particularly for the western volcanoes, cannot be entirely due to small degrees of partial melting in the mantle wedge, considering that they were accompanied by elevations in radiogenic Pb. Elevated Pb ratios are best explained by the introduction of subducted, continentally derived sediments. The sedimentary component in the western volcanoes is probably the South China Sea sediments derived largely from Eurasia. That this component is not available in the Philippine-East Luzon trench is reflected by the fact that the eastern volcanoes

    With the large-scale application of metro MSTP in recent two years, a lot of problems have emerged inevitably. Some more advanced technologies or mechanisms are needed to deal with the application problems of current version MSTP. RPR and MPLS become new focus of enhanced MSTP"s features and the combination of them will boost maturity and further development of enhanced metro MSTP. The MSTP embedded with RPR and MPLS not only find a solution for perfect transport of TDM service, but also improve the support ability for data traffic and bandwidth utilization. With the help of enhanced MSTP, it"s easy for network carriers to provide a reliable, cost-effective, flexible and competitive transport infrastructure delivering various advanced services. RPR firstly solves the conflict between the transport efficiency and QoS of packet service via some mechanisms such as dual counter-rotating ringlet, statistical multiplexing, bandwidth sharing, topology discovery, fairness control etc. Secondly, RPR guarantees the QoS of subscriber by strict service classification and priority. Thirdly, RPR can provide the carrier-class protection within 50ms. On the other hand, MPLS can solve the lack of VLAN ID by LSP labeling and in addition it offers VPN service for different customers then enhances the SLA. Most of all, MPLS provide cross-networking ability, end-to-end service configuration and QoS guarantee, traffic engineering and network optimization. Enhanced MSTP will be applied in convergence or access layer of metro network first. It could have the function of RPR and MPLS at the same time, the reconciliation sub-layer should adopts GFP or LAPS encapsulation, the mapping granularity can be based on VC-12/VC3/VC4-Xc/v and the LCAS should be supported when the transmission channels are configured by virtual concatenation. Enhanced MSTP can be used to build either a single ring network or multi-ring network for improving the ability and quality of Ethernet transportation and

    The aim of this work was to evaluate the efficacy of domestic cooking in inactivating Manila clams experimentally infected with murine norovirus (MNV). A cooking pan was modified to enable electronic temperature probes to be positioned to record both flesh and environment temperature. Manila clams were infected with 10(4) TCID 50% ml(-1) of MNV. The infected whole-in-shell clams, divided into three replicates, were cooked on an electric stove, and groups of nine clams were removed from the pan at fixed intervals. Pools of three digestive glands were examined by virus isolation to ascertain residual viral load. Results showed that 10 min of cooking by a traditional domestic method at a temperature close to 100°C, for at least 2 min, can completely devitalize the MNV in infected clams. This is generally the time needed for the majority of valves to open up. At present, it is highly recommended to label all lagoon products as 'requiring cooking before consumption', but no specifications are given on how long and at what temperature they should be cooked. Our results can provide the consumer with useful indications on how to cook clams to prevent any risk of foodborne illness. © 2013 The Society for Applied Microbiology.

  10. Geological evolution of the West Luzon Basin (South China Sea, Philippines)

    Interpretation of new multichannel seismic data sheds insights into the geologic evolution of the West Luzon Basin (WLB), Philippines. The basin stretches for about 200 km in north-south direction and for up to 50 km in east-west direction. The West Luzon Basin is a sediment-filled trough that is located between the island of Luzon and the outer arc high of the eastward directed subduction of the South China Sea oceanic crust at the Manila Trench. However, at the southern end of the Manila Trench, where its trend changes from N-S to NW-SE and projects towards Mindoro, continental collision occurs (e.g. Lewis & Hayes, 1985). In 2008 approximately 1000 line-kilometres of regional multichannel seismic (MCS) data were obtained in the area of the WLB during a cruise with the German research vessel SONNE. In our MCS data six major unconformities in the WLB separate major stratigraphic units. We interpret high-amplitude, low-frequency reflection bands as acoustic basement that is dissected by normal faults. In the deep parts (4.5-5 s; TWT) of our E-W running seismic profiles we can trace a major fault system with a fault offset of 1-1.5 s (TWT). We suggest an initial development of the structure as a normal fault system, which later was inverted locally. A major change in the depositional regime occurs in the lower part of the sedimentary infill. A distinct bottom simulating reflector (BSR) is commonly observed. Grid calculations of the sediment thickness of the lower stratigraphic units give detailed values of deposition shifts and reveal variations in subsidence of the basin. Based on the depth of bottom simulating reflectors (BSR) heat flow values of 35-40 mW/m2 were calculated, which are typical for forearc basins. Two peculiarities of the WLB are not well in accordance with a forearc setting: The acoustic basement was affected by extensional deformation resulting in normal faulting with fault offsets up to 400 ms (TWT) but extension did not affect sedimentary layers

    The Manila high, an elliptical area 19 km long (N-S) by 6 km wide (E-W) located west-southwest of Big Lake. Arkansas, has less than 3 m of topographic relief. Geomorphic, stratigraphic and chronology data indicate that Big Lake formed during at least two periods of Holocene uplift and subsequent damming of the south-flowing Little River. Age data of an organic mat located at the base of an upper lacustrine deposit indicates an abrupt, possibly tectonic, formation of the present Big Lake between AD 1640 and 1950. We acquired 7 km of high-resolution seismic-reflection data across the northeastern margin of the Manila high to examine its near-surface bedrock structure and possible association with underlying structures such as the Blytheville arch. Sense of displacement and character of imaged faults support interpretations for either a northwest trending, 1.5 km-wide, block of uplifted strata or a series of parallel northeast-trending faults that bound horst and graben structures. We interpret deformation of the Manila high to result from faulting generated by the reactivation of right-lateral strike-slip fault motion along this portion of the Blytheville arch. The most recent uplift of the Manila high may have occurred during the December 16, 1811, New Madrid earthquake. Published by Elsevier Science B.V.

    The oyster ovarian parasite Marteilioides chungmuensis has been reported from Korea and Japan, damaging the oyster industries. Recently, Marteilioides-like organisms have been identified in other commercially important marine bivalves. In this study, we surveyed Marteilioides infection in the Manila clam Ruditapes philippinarum, Suminoe oyster Crassostrea ariakensis, and Pacific oyster Crassostrea gigas, using histology and Marteilioides-specific small subunit (SSU) rDNA PCR. The SSU rDNA sequence of M. chungmuensis (1716 bp) isolated from C. gigas in Tongyoung bay was 99.9% similar to that of M. chungmuensis reported in Japan. Inclusions of multi-nucleated bodies in the oocytes, typical of Marteilioides infection, were identified for the first time in Suminoe oysters. The SSU rDNA sequence of a Marteilioides-like organism isolated from Suminoe oysters was 99.9% similar to that of M. chungmuensis. Marteilioides sp. was also observed from 7 Manila clams of 1840 individuals examined, and the DNA sequences of which were 98.2% similar to the known sequence of M. chungmuensis. Unlike Marteilioides infection of Pacific oysters, no remarkable pathological symptoms, such as large multiple lumps on the mantle, were observed in infected Suminoe oysters or Manila clams. Distribution of the infected Manila clams, Suminoe oysters and Pacific oysters was limited to small bays on the south coast, suggesting that the southern coast is the enzootic area of Marteilioides infection.

    1992-02-01

    A comparative ranking (0-20) of women's status is given for the Philippines and 50 other developed and developing countries on health, education, marriage and children, employment, and social equality. The Philippines is given a rank score of 15.5 on women's health, which places it behind 29 other countries. The score for education was 14.0 for the Philippines, which ties the Philippines with Austria. Marriage and children scores were 14.5 for the Philippines, which places the country lower than 30 other countries. Women's employment scores for the Philippines were 7.5, with the highest score being 14.5 in Sweden. 18 other countries had the same or higher scores. The Philippines had the same score as Japan, Italy, France, and Austria. The Filipino social equality score was 12.5, which was the same score as Japan, Israel, Hong Kong, China, and Benin. 25 countries had the same or higher scores. Women's status is defined as the degree of women's access to and control over material resources and to social resources within the family, the community, and in society at large. Women's status in the Philippines was equitable during the precolonial period and declined under Spanish colonization. The US regime was paternalistic and protective. In 1949 women were again allowed to own property. In 1973 women rights were expanded to include full employment and opportunities. The Philippines endorses completely the UN conventions on the status of women, including special measures to speed up the process of eliminating discrimination against women. A summary is given of various policies and laws in the Philippines pertaining to equality within marriage, family formation, divorce/separation, employment, education, and property ownership.

    2015-01-01

    Background Despite being a cholera-endemic country, data on cholera in the Philippines remain sparse. Knowing the areas where cholera is known to occur and the factors that lead to its occurrence will assist in planning preventive measures and disaster mitigation. Methods Using sentinel surveillance data, PubMed and ProMED searches covering information from 2008–2013 and event-based surveillance reports from 2010–2013, we assessed the epidemiology of cholera in the Philippines. Using spatial log regression, we assessed the role of water, sanitation and population density on the incidence of cholera. Results and Discussion We identified 12 articles from ProMED and none from PubMed that reported on cholera in the Philippines from 2008 to 2013. Data from ProMed and surveillance revealed 42,071 suspected and confirmed cholera cases reported from 2008 to 2013, among which only 5,006 were confirmed. 38 (47%) of 81 provinces and metropolitan regions reported at least one confirmed case of cholera and 32 (40%) reported at least one suspected case. The overall case fatality ratio in sentinel sites was 0.62%, but was 2% in outbreaks. All age groups were affected. Using both confirmed and suspected cholera cases, the average annual incidence in 2010–2013 was 9.1 per 100,000 population. Poor access to improved sanitation was consistently associated with higher cholera incidence. Paradoxically, access to improved water sources was associated with higher cholera incidence using both suspected and confirmed cholera data sources. This finding may have been due to the breakdown in the infrastructure and non-chlorination of water supplies, emphasizing the need to maintain public water systems. Conclusion Our findings confirm that cholera affects a large proportion of the provinces in the country. Identifying areas most at risk for cholera will support the development and implementation of policies to minimize the morbidity and mortality due to this disease. PMID:25569505

    This paper gives an overview of the application of small scale renewable energy sources in the Philippines. Sources looked at include solar, biomass, micro-hydroelectric, mini-hydroelectric, wind, mini-geothermal, and hybrid. A small power utilities group is being spun off the major utility, to provide a structure for developing rural electrification programs. In some instances, private companies have stepped forward, avoiding what is perceived as overwhelming beaurocracy, and installed systems with private financing. The paper provides information on survey work which has been done on resources, and the status of cooperative programs to develop renewable systems in the nation.

    Shell International Petroleum Co. Ltd. negotiated a farmout in 1990 from Occidental International Exploration and Production Co. for Block SC-38 in the South China Sea off Palawan, Philippines, following Oxy's discovery of gas in 1989 in a Miocene Nido limestone buildup. Under the terms of the farmout agreement, Shell became operator with a 50% share. Following the disappointing well North Iloc 1, Shell was successful in finding oil and gas in Malampaya 1. Water 700-1,000 m deep, remoteness, and adverse weather conditions have imposed major challenges for offshore operations.

    Thiamethoxam (ACTARA® 25WG) was evaluated for its termiticidal properties against three species of economically important subterranean termites (Isoptera: Termitidae) in the Philippines: Nasutitermes luzonicus Oshima, Macrotermes gilvus Hagen, and Microcerotermes losbanosensis Oshima. Results of the study indicated that exposure to soil or ingestion of paper treated with thiamethoxam at concentration above 0.41 ppm may provide an adequate chemical barrier or induce high mortality against N. luzonicus, M. gilvus and M. losbanosensis after 5–9 days. Feeding bioassays showed that thiamethoxam was not repellent to M. gilvus and M. losbanosensis but had an anti-feeding effect on N. luzonicus. PMID:20302537

Discussed are issues relating not only to the recipients of the health services and control programs but also to the people in the control program and disease control managers. Marinduque, a recently described endemic focus of lymphatic filariasis, is used to illustrate the many problems affecting the control efforts in the Philippines. The true impact of the problem has not been described lately, hence the need for epidemiologic, social, and economic impact studies.

    The southern termination of the Ryukyu arc-trench system underwent a complex polyphased and extremely rapid tectonic evolution during the last 5 to 8 My. At first, the relative motion of the Philippine Sea plate (PSP) has changed about 5 My ago from a northward to a northwestward motion relative to Eurasia. Secondly, the Ryukyu trench has propagated from east to west during the same time period resulting in a tectonic inversion along the former passive margin of the South China Sea into the active margin of the S-Ryukyu trench. Thirdly, the convergence rate along the neo-formed S-Ryukyu trench dramatically increased from 8 to 13 cm/yr since at least 2 My when the Southern Okinawa Trough (SOT) started to rift. At the same time, the oceanic subduction of the South China Sea beneath the northern Manila arc progressively evolved into a continental subduction of the Chinese platform at the origin of the Taiwan orogen. The timing of these various kinematic and tectonic events should have been recorded in the deformed sedimentary basins and fold-and-thrust belts in the region. Unfortunately, a large part is now below the sea-level and no or a few age constraints are available. The recent joint project between Taiwan-USA & France (TAIGER & ACTS) gave us the opportunity to considerably increase the resolution of the seismic imagery around the island and especially in the most highly deformed area east of Taiwan along the S-Ryukyu forearc. We already knew that the seismic activity focussed in this region but we ignored how the converging plates deformed. We can now argue that the PSP strongly deforms in the vicinity of its deep interaction with the root of the Taiwan orogen. The north-dipping PSP slab buckles and tears along two diverging directions with a down-faulted part subducting beneath the SOT.

    The United Nations has called for countries to improve access to mobility devices when needed. The World Health Organization has published guidelines on the provision of manual wheelchairs in less-resourced settings. Yet little is known about the extent to which appropriate wheelchairs are available and provided according to international guidelines. This study's purpose was to describe wheelchair users' experiences receiving services and acquiring wheelchair skills in urban and peri-urban areas of Kenya and the Philippines. Local researchers in Nairobi and Manila interviewed 48 adult basic wheelchair users, with even distribution of those who had and had not received wheelchair services along with their wheelchair. Recordings were transcribed in the local language and translated into English. The study team coded transcripts for predetermined and emergent themes, using Atlas-ti software. A qualitative content analysis approach was taken with the WHO service delivery process as an organizing framework. Wheelchair users frequently described past experiences with ill-fitting wheelchairs and little formal training to use wheelchairs effectively. Through exposure to multiple wheelchairs and self-advocacy, they learned to select wheelchairs suitable for their needs. Maintenance and repair services were often in short supply. Participants attributed shorter duration of wheelchair use to lack of repair. Peer support networks emerged as an important source of knowledge, resources and emotional support. Most participants acknowledged that they received wheelchairs that would have been difficult or impossible for them to pay for, and despite challenges, they were grateful to have some means of mobility. Four themes emerged as critical for understanding the implementation of wheelchair services: barriers in the physical environment, the need for having multiple chairs to improve access, perceived social stigma, and the importance of peer support. Interventions are needed to

While the signs of this disease in bivalve larvae are well known, the infection process by pathogenic Vibrio spp. during episodes of vibriosis has not been elucidated. To investigate the infection process in bivalves, the pathogens of larvae as V. tubiashii subsp. europaensis, V. neptunius and V. bivalvicida were tagged with green fluorescent protein (GFP). Larvae of Manila clam (Ruditapes philippinarum) were inoculated with the GFP-labeled pathogens in different infection assays and monitored by microscopy. Manila clam larvae infected by distinct GFP-tagged Vibrio spp. in different challenges showed the same progression in the infection process, defining three infection stages. GFP-tagged Vibrio spp. were filtered by the larvae through the vellum and entered in the digestive system through the esophagus and stomach and colonized the digestive gland and particularly the intestine, where they proliferated during the first 2h of contact (Stage I), suggesting a chemotactic response. Then, GFP-tagged Vibrio spp. expanded rapidly to the surrounding organs in the body cavity from the dorsal to ventral region (Stage II; 6-8h), colonizing the larvae completely at the peak of infection (Stage III) (14-24h). Results demonstrated for the first time that the vibriosis is asymptomatic in Manila clam larvae during the early infection stages. Thus, the early colonization and the rapid proliferation of Vibrio pathogens within the body cavity supported the sudden and fatal effect of the vibriosis, since the larvae exhibited the first signs of disease when the infection process is advanced. As a first step in the elucidation of the potential mechanisms of bacterial pathogenesis in bivalve larvae the enzymatic activities of the extracellular products released from the wild type V. neptunius, V. tubiashii subsp. europaensis and V. bivalvicida were determined and their cytotoxicity was

    Hepatitis C virus (HCV) is currently classified into at least six major genotypes, each of which is further divided into a number of subtypes. It has been reported that prevalence of each subtype varies among different geographical regions of the world and that severity of liver disease and sensitivity to interferon treatment varies with different subtypes. The purpose of this study was to determine and compare the prevalence of each subtype among HCV isolates in different areas in Asia such as southern (Hat Yai) and northern (Chiang Mai) parts of Thailand, Indonesia (Surabaya), the Philippines (Manila) and Japan (Kobe). Sera were obtained from various groups of patients and tested for antibodies against HCV using second and/or third generation ELISA kits. RNA was extracted from anti-HCV-positive sera and reverse-transcribed into cDNA. The cDNA-preparations were subjected to nested PCR to amplify NS5B and 5'-untranslated region (5'UTR) sequences. Amplified fragments were sequenced and subtypes of the isolates were determined based on sequence similarities with reported sequences. In Chiang Mai and Hat Yai, Thailand, HCV-3a, HCV-1a and HCV-1b were common in various populations. HCV type 6 variants were commonly found among blood donors and drug addicts in Chiang Mai, but not in Hat Yai. In Surabaya, Indonesia, HCV-2a was frequently detected in blood donors, but less frequently in patients with chronic liver disease. In blood donors, HCV-1a, HCV-1b and HCV-1d were more strongly associated with elevation of serum aminotransferase levels than HCV-2a. HCV-1a was significantly more common in patients on maintenance hemodialysis than in blood donors or patients with chronic liver disease. HCV-1d was detected exclusively in Indonesia. Another unique subtype HCV-3g was found also in Indonesia, though less frequently than HCV-1d. In the Philippines, a vast majority of the isolates were either HCV-1a or HCV-1b. Thus, HCV subtype prevalence varies among different regions of

  16. Metro Optical Networks for Homeland Security

    Bechtel, James H.

    Metro optical networks provide an enticing opportunity for strengthening homeland security. Many existing and emerging fiber-optic networks can be adapted for enhanced security applications. Applications include airports, theme parks, sports venues, and border surveillance systems. Here real-time high-quality video and captured images can be collected, transported, processed, and stored for security applications. Video and data collection are important also at correctional facilities, courts, infrastructure (e.g., dams, bridges, railroads, reservoirs, power stations), and at military and other government locations. The scaling of DWDM-based networks allows vast amounts of data to be collected and transported including biometric features of individuals at security check points. Here applications will be discussed along with potential solutions and challenges. Examples of solutions to these problems are given. This includes a discussion of metropolitan aggregation platforms for voice, video, and data that are SONET compliant for use in SONET networks and the use of DWDM technology for scaling and transporting a variety of protocols. Element management software allows not only network status monitoring, but also provides optimized allocation of network resources through the use of optical switches or electrical cross connects.

  17. Philippines to seek Thai assistance in fighting AIDS.

    PubMed

    A group of Philippine officials left for Thailand to learn from the Thai government's experience in fighting AIDS. Thailand has one of the highest AIDS levels in Asia and has instituted a variety of public and private programs to deal with the disease. Health Undersecretary Carmencita Reodica, who is leading the delegation, said the Philippines does not expect as many AIDS cases as Thailand. "But if the Philippines does not improve its planning and surveillance system, we could face the same threat in the future," she said. Thailand has a good surveillance program, valuable support services such as mobile clinics, and active private groups fighting AIDS, she said. The group is to meet with Prime Minister Banharn Silpa-archa, who heads the Thai National AIDS Council, and other officials involved in Thailand's anti-AIDS campaign. Thailand has recorded 22,135 AIDS cases and 750,000 people with HIV. In comparison, the Philippine government has documented only 234 AIDS cases in the Philippines and 704 people with HIV. Health officials estimate that as many as 35,000 people in the country are infected with HIV. While Thailand monitors the number of AIDS cases in the general population, the Philippines only monitors the disease among so-called high-risk groups such as prostitutes, homosexuals, and intravenous drug users. Reodica said legislation is needed in the Philippines to support the country's AIDS program, as well as to answer ethical and legal issues concerning AIDS cases. full text

    The Philippine archipelago is globally one of the most important model island systems for studying evolutionary processes. However, most plant species on this archipelago have not yet been studied in sufficient detail. The main aim of this study is to unravel the evolutionary history and biogeographic relationships of the Philippine members of the pantropical genus Ixora. The complex plastid and nuclear divergence patterns in Philippine Ixora, documented using tree and network approaches, reveal a highly dynamic evolution in Ixora, involving several phases of radiation and recolonization. Philippine Ixora comprises at least five lineages, of which one is most closely related to species from Wallacea, and the remaining four to species from Asia. Our study highlights the importance of Philippine species for understanding phytogeographic patterns in the Indomalayan-Australasian eco-region. The overall genetic differentiation, as well as the incongruence between genealogies based on the biparentally inherited nucleome and the maternally inherited plastome in Ixora, reflect the complex tectonic history of the Philippine archipelago. The Ixora lineage related to Wallacean species supports the delimitation of different ecozones along Huxley's line, because it is absent from Palawan. The remaining four lineages are all allied with Asian taxa, reflecting several waves of colonization. Close relationships between some widespread Philippine species and locally adapted narrow endemics suggest that the widespread, genetically diverse species act as pools for the formation of new species in a process of ongoing speciation. Our results suggest that the species concepts of some of the more widespread taxa need to be revised.

  19. Philippines. Church vs. state: Fidel Ramos and family planning face "Catholic Power".

    PubMed

    1994-08-24

    Catholic groups and individuals united in a public rally in Manila's Rizal Park to decry a "cultural dictatorship," which promotes abortion, homosexuality, lesbianism, sexual perversion, condoms, and artificial contraception. Government spokesmen responded that condoms and contraception were part of government policy to spread family planning knowledge and informed choices among the population. Cardinal Jaime Sin and former president Corazon Aquino joined forces to lead the movement against the national family planning program in the largest demonstration since the ouster of Ferdinand Marcos in 1986. Also criticized was the 85-page draft action plan for the International Conference on Population and Development (ICPD) scheduled for September 1994. Cardinal Sin accused President Clinton of using the action plan to promote worldwide abortion. Under the administration of President Fidel Ramos, family planning funding has quintupled and the number of family planning workers has increased from 200 to 8000. President Ramos has gone the farthest of any administration in opposing the Church's positions on contraception and abortion, although years ago Fidel Ramos and Cardinal Sin were allies in the effort to push out Ferdinand Marcos. The population of the Philippines is 85% Catholic, and laws reflect the Church's doctrine against divorce and abortion. The current growth rate is 2.3%, and the goal is to reduce growth to 2.0% by 1998, the end of Ramos's term in office. The population target is in accord with demographic goals proposed in the UN draft action plan. The Vatican has opposed the language in the plan and may have encouraged other religious leaders to join those opposed to the "war against our babies and children." Sin said that contraceptive distribution was "intrinsically evil" and should be stopped now. Ramos's administration stated that their policies and programs are not "in the hands of the devil" and there is support for the Church on family values and

    Population policy of the Philippine government is discussed in its evolution, current status under the 1973 constitution, and future development. Despite the low income, strong family ties, 7000 islands, 87 languages and 82% Catholic population, the Philippines has an official population policy which evolved into the Population Commission in 1969. The commission recommended setting goals, furthering education, removing legal drawbacks, reducing mortality, regulating internal migration and coordinating public and private international funding organizations. The private organizations, international funding,mass media, academic influence, and possibly the Catholic hierarchy influenced events positively. During martial law (September 1972 to January 1973) the government took on responsibility to require licensed professionals to learn family planning, and to change tax exemptions. The constitution now states that the State must achieve a population level conducive to national welfare. The present policy considers population planning an economic priority, has placed 5 cabinet members on the board of the Population Commission (no representatives from private organizations, which recruit 70% of acceptors), and has an extremely optimistic 5 year plan. No public protest had emerged, and because rhythm is included, it is hoped that rhythm users well eventually change to effective methods. Foreign assistance will be needed, and is channeled through the National Economic and Development Authority. Future needs include paramidics, nonclinical methods, rural access, incentives for program workers, and more effective propaganda.

    In anticipation of tightening sulfur specifications on diesel fuel, Petron Corp. built a new 18,000 b/sd gas oil desulfurization unit (GODU) at its refinery in Bataan, Philippines. The GODU gives Petron sufficient diesel oil desulfurization capacity to meet demand for lower-sulfur diesel in the country. The project places the refinery in a pacesetter position to comply with the Philippine government`s moves to reduce air pollution, especially in urban centers, by reducing the sulfur specification for diesel to 0.5 wt% in 1996 from 0.7 wt% at the start of the project. Performance tests and initial operations of the unit have revealed a desulfurization efficiency of 91% vs. a guaranteed efficiency of 90%. A feed sulfur content of 1.33 wt% is reduced to 0.12 wt% at normal operating conditions. Operating difficulties during start-up were minimized through use of a detailed prestartup check conducted during the early stages of construction work.

    Three new begomovirus isolates and one betasatellite were obtained from a tomato plant exhibiting leaf curl symptom in Laguna, the Philippines. Typical begomovirus DNA components representing the three isolates (PH01, PH02 and PH03) were cloned, and their full-length sequences were determined to be 2754 to 2746 nucleotides. The genome organizations of these isolates were similar to those of other Old World monopartite begomoviruses. The sequence data indicated that PH01 and PH02 were variants of strain B of the species Tomato leaf curl Philippines virus, while PH03 was a variant of strain A of the species Tomato leaf curl Philippines virus. These isolates were designated ToLCPV-B[PH:Lag1:06], ToLCPV-B[PH:Lag2:06], and ToLCPV-A[PH:Lag3:06], respectively. Phylogenetic analysis revealed that the present isolates form a separate monophyletic cluster with indigenous begomoviruses reported earlier in the Philippines. A betasatellite isolated from same sample belongs to the betasatellite species Tomato leaf curl Philippines betasatellite and designated Tomato leaf curl Philippines betasatellite-[Philippines:Laguna1:2006], ToLCPHB-[PH:Lag1:06]. When co-inoculated with this betasatellite, tomato leaf curl Philippines virus induced severe symptoms in N. benthamiana and Solanum lycopersicum plants. Using a PVX-mediated transient assay, we found that the C4 and C2 proteins of tomato leaf curl Philippines virus and the βC1 protein of ToLCPHB-[PH:Lag1:06] function as a suppressor of RNA silencing.

    Manila clam stock from Arcachon Bay, France, is declining, as is commercial harvest. To understand the role of environmental biotic interactions in this decrease, effects of a toxic dinoflagellate, Alexandrium ostenfeldii, which blooms regularly in Arcachon bay, and the interaction with perkinsosis on clam physiology were investigated. Manila clams from Arcachon Bay, with variable natural levels of perkinsosis, were exposed for seven days to a mix of the nutritious microalga T-Iso and the toxic dinoflagellate A. ostenfeldii, a producer of spirolides, followed by seven days of depuration fed only T-Iso. Following sacrifice and quantification of protozoan parasite Perkinsus olseni burden, clams were divided into two groups according to intensity of the infection ("Light-Moderate" and "Moderate-Heavy"). Hemocyte and plasma responses, digestive enzyme activities, antioxidant enzyme activities in gills, and histopathological responses were analyzed. Reactive oxygen species (ROS) production in hemocytes and catalase (CAT) activity in gills increased with P. olseni intensity of infection in control clams fed T-Iso, but did not vary among A. ostenfeldii-exposed clams. Exposure to A. ostenfeldii caused tissue alterations associated with an inflammatory response and modifications in hemocyte morphology. In the gills, superoxide dismutase (SOD) activity decreased, and an increase in brown cell occurrence was seen, suggesting oxidative stress. Observations of hemocytes and brown cells in tissues during exposure and depuration suggest involvement of both cell types in detoxication processes. Results suggest that exposure to A. ostenfeldii disrupted the pro-/anti-oxidant response of clams to heavy P. olseni intensity. In addition, depressed mitochondrial membrane potential (MMP) in hemocytes of clams exposed to A. ostenfeldii suggests that mitochondrial functions are regulated to maintain homeostasis of digestive enzyme activity and condition index.

    New marine seismic reflection and coincident wide-angle ocean-bottom seismometer data acquired offshore Taiwan provide high-resolution constraints on the crustal structure of an incipient mountain belt during the earliest stage of arc-continent collision. The new seismic reflection image and travel-time tomography velocity model show evidence for crust of the distal southern Chinese continental margin being subducted eastward beneath the Manila trench and underplated to the accretionary wedge before collision with the southern Chinese continental shelf. The distal margin crust consists of highly extended continental crust interspersed with volcanic bodies and a high-velocity lower crustal layer of likely magmatic intrusions. The distal margin crust is 10-14 km thick outboard of the trench, but thins to 6 km thick beneath the lower slope of the Manila trench accretionary wedge. Along the lower slope of the accretionary prism, we image westward-verging imbricate thrusts and folded strata up to 10 km thick. A sharp decrease in bathymetry marks the transition from lower to upper slope, where we observe a fast (>6.0 km/s) seismic velocity anomaly at the base of the wedge that we interpret as structurally underplated crust from the distal continental margin. Our results support a model of arc-continent collision in Taiwan where the accretionary wedge is first thickened by structural underplating of distal margin crust prior to collision with the continental shelf. The crustal rocks exposed throughout the Central Range in Taiwan may be similarly derived from subducted and structurally underplated crust from the highly extended distal continental margin.

    Lysozymes play an important role in the innate immune responses with which mollusks respond to bacterial invasion through its lytic activity. In the present study, two c-type lysozymes (designed as VpCLYZ-1 and VpCLYZ-2, respectively) were identified and characterized from the manila clam Venerupis philippinarum. The full-length cDNA of VpCLYZ-1 and VpCLYZ-2 was of 629 and 736 bp, encoding a polypeptide of 156 and153 amino acid residues, respectively. The deduced amino acid sequences of VpCLYZs showed high similarity to other known invertebrate c-type lysozymes. Multiple alignments and phylogenetic relationship strongly suggested that VpCLYZ-1 and VpCLYZ-2 belonged to the c-type lysozyme family. Both VpCLYZ-1 and VpCLYZ-2 transcripts were constitutively expressed in a wide range of tissues with different levels. The VpCLYZ-1 transcript was dominantly expressed in hepatopancreas and hemocytes, while VpCLYZ-2 transcript was mainly expressed in the tissues of hepatopancreas and gills. Both the mRNA expression of VpCLYZ-1 and VpCLYZ-2 was significantly up-regulated at 12 h post Vibrio anguillarum challenge. The recombinant VpCLYZ-1 and VpCLYZ-2 (designed as rVpCLYZ-1 and rVpCLYZ-2) exhibited lytic activity against all tested bacteria, and rVpCLYZ-1 showed higher activities than rVpCLYZ-2 in killing Micrococcus luteus and V. anguillarum. Overall, our results suggested that VpCLYZ-1 and VpCLYZ-2 belonged to the c-type lysozyme family, and played important roles in the immune responses of manila clam, especially in the elimination of pathogens.

    The protistan parasite Perkinsus olseni is a deadly causative agent of perkinsosis, a molluscan disease affecting Manila clam (Ruditapes philippinarum), having a significant impact on world mollusc production. Deciphering the underlying molecular mechanisms in R. philippinarum-P. olseni interaction is crucial for controlling this parasitosis. The present study investigated the transcriptional expression in the parasite trophozoite using RNA-seq. Control and treatment (in vitro challenged with Manila clam-plasma) P. olseni trophozoite RNA were extracted and sequenced on the Illumina HiSeq 2000 instrument using a 100-bp paired-end sequencing strategy. Paired reads (64.7 million) were de novo assembled using Trinity, and the resultant transcripts were further clustered using CAP3. The re-constructed P. olseni transcriptome contains 47,590 unique transcripts of which 23,505 were annotated to 9764 unique proteins. A large number of genes were associated with Gene Ontology terms such as stress and immune-response, cell homeostasis, antioxidation, cell communication, signal transduction, signalling and proteolysis. Among annotated transcripts, a preliminary gene expression analysis detected 679 up-regulated and 478 down-regulated genes, linked to virulence factors, anti-oxidants, adhesion and immune-response molecules. Genes of several metabolic pathways such as DOXP/MEP, FAS II or folate biosynthesis, which are potential therapeutic targets, were identified. This study is the first description of the P. olseni transcriptome, and provides a substantial genomic resource for studying the molecular mechanisms of the host-parasite interaction in perkinsosis. In this sense, it is also the first evaluation of the parasite gene expression after challenge with clam extracellular products. Copyright © 2016 Elsevier Inc. All rights reserved.

    Manila clams sampled in Seonjae Island, Korea with shell lengths (SL) below 19.76 mm in average showed a significantly depleted carbon and nitrogen isotope values (P<0.05) by 0.80~1.41 %. This size related variation can be caused by either altered carbon and nutrient source or by affected isotopic incorporation rates and discrimination factors. In order to examine size-related diet shift in manila clams, R. philippinarum with different sizes that were constantly fed on known mixed microalgae for several months were sampled from Incheon Fisheries Hacheries Research Institute (IFRI). These manila clams have shown a high intra-species variation in growth rate with a maximum difference of more or less 2.30 cm. The smallest size groups (3.68±0.17 mm and 6.88±0.21 mm) obtained their nutrition from both P. tricornutum and aggregated organic matter that consists of dead or decomposed microalgae or other detritus. Bigger size groups (10.92±0.34 mm and 14.81±0.25 mm) obtained most of their energy from P.tricorutum and also from other phytoplankton unlike the biggest size group (21.15±1.02 mm) that feeds mainly on fresh microalgae of all diets fed. This variation in diet reveals that smaller clams mostly inhale dead or decomposed microalgae that sinks on the bottom while the bigger clams uptake more fresh ones that are still alive. This variation in feeding behavior could have been caused by morphological constraints such as limited siphon length. The results suggest that manila clams greater than and below 19.76 mm in average have different feeding behavior and P. tricornutum and I. galbana were the two most preferred diets for manila clams cultured in IFHRI. The result of fatty acid composition of manila clams in relation to size or growth rate suggests that fast growing clams would have rapid metabolism of fatty acids not required by the animals and an accumulation of the essential fatty acids (PUFA). In addition, their higher energy requirement and more active state

    Rabies is a fatal disease, claiming the lives of around 59,000 people annually worldwide. It is considered a neglected and underreported disease leading to inadequate support from governments. Apart from dog vaccination and proper animal bite management, an integral part of a successful rabies control program is community education. The Philippine government conducts an extensive nationwide annual World Rabies Day (WRD) celebration as part of its community education. Strong inter-sectoral collaboration at the national level is a key factor for the success of WRD, capitalizing on the partners' strengths to mobilize various sectors. Strategies include the National WRD Celebration and releasing national government memorandums. An invitation letter campaign was initiated, encouraging stakeholders to register their activities. Banners were given as an incentive for those who registered. Mass and social media were also utilized to promote WRD. Registered WRD events held in the Philippines rose from 10 events in 2012, to 37 events in 2013, to 66 events in 2014 and 76 events in 2015. The individual activities involved veterinary services and information, communication, and education (IEC) activities. Nine unique WRD IEC activities are highlighted in this paper. Promotion of WRD through social media was also utilized in recent years. More news items were published online than those printed in newspapers and aired on television. The campaign's success underlines the value of a national government-led program. The national rabies program sets the agenda for priority activities including the WRD campaign. Its capacity to allocate funds for the program also denotes stability which is beneficial for local program implementers. Different segments of society were tapped through various strategies. The campaign's flexibility allowed for a large range of activities and presented opportunities for expanding partnerships and integration with others interventions for its sustainability

    On 15 December 2015, Typhoon Melor made landfall in Oriental Mindoro, Philippines, the eastern province of an island more than 120 km south of Manila. The typhoon brought heavy rains that generated debris flows in multiple watersheds in the municipality of Baco while subsequently triggering debris flows on the watersheds that lined the Digdig segment of the Philippine Fault in the provinces of Aurora and Nueva Ecija, more than 300 km north of Mindoro island. In this study, ground mapping and interviews were conducted in the affected watersheds of Baco, Dingalan in Aurora, as well as Bongabon, Gabaldon, and Laur in Nueva Ecija to determine the extent, lithology, and grain size distribution of the debris-flow deposits. IfSAR images acquired in 2013 and Landsat 8 satellite images were then utilized to determine the watershed characteristics of these areas and to identify the factors that triggered debris flows in each one. Global Satellite Mapping of Precipitation (GSMaP) data was then used to generate intensity-duration plots of the typhoon rainfall for each of the watersheds. Known global thresholds of debris flows and the time of debris-flow occurrence derived from interviews were graphed on the plots to determine the best fit to characterize the debris-flow events. IfSAR images used in characterizing the deposits were utilized to run Flow-R, a Matlab-compiled numerical model for regional scale debris-flow assessments. The same images were used to run FLO-2D, a flood-routing software that has been extensively used for mudflow simulations. Lastly, the IfSAR images were utilized to simulate Debris-2D, another debris flow simulation program. Results show that whereas Flow-R is better suited to assess the probability of debris flows on a larger area prior to an event, Debris-2D and FLO-2D can both generate a more detailed hazard map of an area. Between the two latter programs, Debris-2D can be better simulated even without prior knowledge of debris flows occurring in

    In a country in which contraception is controversial, abortion illegal and in which reproductive rights are limited, IVF is an unaffordable dream for most couples. But things are slowly changing in the only Christian democracy in Asia: the Philippines. In December 2012 the Senate passed the Reproductive Health bill and president Benigno Aquino III signed the measure into a law which is still not implemented due to the opposition of the ultra-orthodox Roman Catholic Church. However, the more liberal perspective of pope Francis on sexuality and human reproduction may have an positive impact on this issue. While government funding for contraceptives is still being opposed, the IVF market is estimated to grow considerable. This creates promising opportunities. PMID:24753955

  3. Fertility continues to decline in Philippines.

    1999-01-01

    During the National Dissemination Seminar of the 1998 Philippine National Demographic and Health Survey, panelists highlighted the national decline in fertility from 4.1 children/woman in 1990-93 to 3.7 in 1995-98. This decline is accompanied by an increase in contraceptive use, with traditional methods accounting to 40% of all contraception used. Prevalence of contraceptive use is 47%, with female sterilization as the most common method. However, there still exists a 40% contraceptive discontinuation, which was largely attributed to contraceptive failure resulting to unplanned pregnancy. In response, the National Seminar planned the implementation of workshops at the regional level to present survey findings and elicit feedback on the implications and possible solutions to the problems encountered. Furthermore, analyses studies are underway on fertility preferences and the transition of the two child norms, and contraceptive use dynamics.

    Nematodes are considered major pests on most economic crops in the Philippines, particularly on banana, pineapple, citrus, tomato, ramie, and sugarcane. Radopholus similis is the most destructive nematode on banana, while Meloidogyne spp. are more serious on various vegetable crops such as tomato, okra, and celery and on fiber crops such as ramie. Tylenchulus semipenetrans is a problem on citrus and Rotylenchulus reniformis on pineapple and some legume crops. Hirschmanniella oryzae and Aphelenchoides besseyi are becoming serious on rice, and Pratylenchus zeae is affecting corn in some areas. Lately, Globodera rostochiensis has been causing serious damage on potato in the highlands. Control measures such as crop rotation, planting resistant varieties, chemical nematicide application, and biological control have been recommended to control these nematodes. PMID:19290204

    This study investigates the effects of climatic variations and extremes captured by variability in temperature, precipitation, and incidents of typhoons on aggregate inter-provincial migration within the Philippines using panel data. Our results indicate that a rise in temperature and to some extent increased typhoon activity increase outmigration, while precipitation does not have a consistent, significant effect. We also find that temperature and typhoons have significant negative effects on rice yields, a proxy for agricultural productivity, and generate more outmigration from provinces that are more agriculturally dependent and have a larger share of rural population. Finally, migration decisions of males, younger individuals, and those with higher levels of education are more sensitive to rising temperature and typhoons. We conclude that temperature increase and to some extent typhoon activities promote migration, potentially through their negative effect on crop yields. The migration responses of males, more educated, and younger individuals are more sensitive to these climatic impacts.

    Limited quantitative research has been conducted on coral disease in the Philippines and baseline data are much needed. Field surveys for prevalence and distribution patterns were conducted from November 2002 to August 2003. Sites included the islands of Negros, Cebu, Siquijor, Panglao, Olango, Sumilon, Bantayan, Pescador, Balicassag and Palawan. In 154 belt transects, 10 026 Porites colonies were examined at 28 sites covering 3080 m2. Two syndromes, Porites ulcerative white spot (PUWS) and coral tumors, occurred at high prevalence. Tumors as high as 39.1% occurred among massive Porites, and PUWS was as high as 53.7% among massive and branching Porites. In 8 mo, 116 tagged colonies showed slow progression and low mortality. Along a 41 km human impact gradient centered on Dumaguete City (Negros), 15 sites were examined. Correlation analyses linked higher disease prevalence to anthropogenic influence (Spearman's rank correlation coefficient [r(s)] = -0.54, p = 0.04 for tumors and r(s) = -0.69, p = 0.005 for PUWS). In most sites disease prevalence was lower than in the sites near Dumaguete. High PUWS prevalence near uninhabited Sumilon Island appeared to be linked to the highly diseased reefs near Dumaguete City due to transmission of disease along a cross-shelf front formed between the Tañon Strait and Bohol Sea. Other observations included 12 potential new host species for PUWS (4 new genera and 1 octocorallia) and 5 likely new hosts for black band disease (BBD) in the Philippines, and a relatively high prevalence (7.8%) of BBD in 1 site in western Palawan.

    Mollusks lack an adaptive immune system and rely solely on the innate immune response. The nuclear factor-kappa B (NF-κB) signaling pathway is one of the most important components of the innate immune system and its activity is regulated by physical interaction with the inhibitor of NF-κB (IκB) protein. The manila clam, Ruditapes philippinarum (Rp), is a key species of the world's aquaculture industry, and recent pathogenic threats, such as the Gram-negative lipopolysaccharide (LPS)-expressing Vibrio tapetis bacteria, have produced severe adverse economic impacts. Here, we describe identification, characterization and immune responses of novel IκB (Rp-IκB) in the manila clam. The Rp-IκB cDNA is comprised of a 1,032 bp open reading frame, which encodes 343 amino acid residues and has a predicted molecular mass of 38 kDa. The Rp-IκB protein exhibits typical structural features of IκB family members, including the IκB degradation motif, PEST sequence, and six ankyrin repeats. Phylogenetic analysis showed that manila clam and other known molluscan IκB proteins grouped together in the invertebrate cluster. Analysis of the tissue expression distribution revealed that Rp-IκB was ubiquitously expressed. However, immune challenge with V. tapetis and purified LPS endotoxin induced significant up-regulation of Rp-IκB expression in gill and hemocytes. These results indicated that Rp-IκB may play an important role in manila clam defense against bacterial infection.

    Coastal ecosystem modifications have contributed to the spread of introduced species through alterations of historic disturbance regimes and resource availability, and increased propagule pressure. Frequency of occurrence of the Manila clam (Venerupis phillipinarum, Veneridae) in Southern California estuaries has increased from absent or sparse to common since the mid-1990s. Potential invasion vectors include seafood sales and aquaculture, and spread from established northern populations over decades. The clam’s post-settlement habitat preferences are, however, uncertain in this region. Our project aimed to identify factors associated with established patches of the clam within a bay toward the southern end of this introduced range. During summer 2013, we sampled 10 tidal flat sites in Mission Bay, San Diego; each containing an area with and without hard structure (e.g., riprap, boulders). We measured likely environmental influences (e.g., sediment variables, distance to ocean). Manila clam densities across the bay were most strongly associated with site, where highest densities were located in the northern and/or back halves of the bay; and weakly correlated with lower porewater salinities. Within sites, Manila clam density was enhanced in the presence of hard structure in most sites. Prevailing currents and salinity regimes likely contribute to bay wide distributions, while hard structures may provide suitable microhabitats (refuge from predators and physical stress) and larval entrapment within sites. Results provide insights into decisions about future shoreline management efforts. Finally, we identify directions for future study to better understand and therefore predict patterns of establishment of the Manila clam in the southern portion of its introduced range.

    An extensive air quality campaign was performed at differently designed station platforms in the Barcelona metro system, aiming to investigate the factors governing airborne particle number (N) concentrations and their size distributions. The study of the daily trends of N concentrations by different size ranges shows that concentrations of N0.3-10 are closely related with the schedule of the metro service. Conversely, the hourly variation of N0.007-10 (mainly composed of ultrafine particles) could be partly governed by the entrance of particles from outdoor emissions through mechanical ventilation. Measurements under different ventilation settings at three metro platforms reveal that the effect on air quality linked to changes in the tunnel ventilation depends on the station design. Night-time maintenance works in tunnels are frequent activities in the metro system; and after intense prolonged works, these can result in higher N concentrations at platforms during the following metro operating hours (by up to 30%), this being especially evident for N1-10. Due to the complex mixture of factors controlling N, together with the differences in trends recorded for particles within different size ranges, developing an air quality strategy at metro systems is a great challenge. When compared to street-level urban particles concentrations, the priority in metro air quality should be dealing with particles coarser than 0.3 μm. In fact, the results suggest that at narrow platforms served by single-track tunnels the current forced tunnel ventilation during operating hours is less efficient in reducing coarse particles compared to fine.

    Manila clam Ruditapes philippinarum is one of the most important economic species in shellfishery in China due to its wide geographic distribution and high tolerance to environmental changes (e.g., salinity, temperature). In addition, Manila clam is a good biomonitor/bioindicator in "Mussel Watch Programs" and marine environmental toxicology. However, there are several pedigrees of R. philippinarum distributed in the marine environment in China. No attention has been paid to the biological differences between various pedigrees of Manila clams, which may introduce undesirable biological variation in toxicology studies. In this study, we applied NMR-based metabolomics to detect the biological differences in two main pedigrees (White and Zebra) of R. philippinarum and their differential responses to heavy metal exposures (Cadmium and Zinc) using adductor muscle as a target tissue to define one sensitive pedigree of R. philippinarum as biomonitor for heavy metals. Our results indicated that there were significant metabolic differences in adductor muscle tissues between White and Zebra clams, including higher levels of alanine, glutamine, hypotaurine, phosphocholine and homarine in White clam muscles and higher levels of branched chain amino acids (valine, leucine and isoleucine), succinate and 4-aminobutyrate in Zebra clam muscles, respectively. Differential metabolic responses to heavy metals between White and Zebra clams were also found. Overall, we concluded that White pedigree of clam could be a preferable bioindicator/biomonitor in marine toxicology studies and for marine heavy metals based on the relatively high sensitivity to heavy metals.

    The distribution and bioaccumulation features of PCBs, DDTs, and HCHs were investigated in the sediments and Manila clams collected from along the Mid-Western coast of Korea. The measured concentrations of ΣPCBs, ΣDDTs and ΣHCHs were 1.08-3.5, 0.12-0.35 and 0.090-0.30 ng g(-1) dw in sediment, and 33-390, 7.4-46 and 6.3-27 ng g(-1) lipid in Manila clam, respectively. Their levels were found to be relatively lower than those of other contaminated areas and the consumption of Manila clam from these areas seems to be safe for human health according to calculated lifetime cancer risk and hazard indices. The ΣPCBs and ΣDDTs concentrations in sediments showed a significant relationship to those in clams. The significant correlation was observed between BSAF in clams and Kow for each PCB congeners and DDT metabolites. These findings support that the PCBs and DDTs levels, which are highly hydrophobic chemicals, in clam reflect the sediment pollution through bioaccumulation.

    Metros (heavy rail transit systems) are integral parts of urban transportation systems. Failures in their operations can have serious impacts on urban mobility, and measuring their robustness is therefore critical. Moreover, as physical networks, metros can be viewed as topological entities, and as such they possess measurable network properties. In this article, by using network science and graph theory, we investigate ten theoretical and four numerical robustness metrics and their performance in quantifying the robustness of 33 metro networks under random failures or targeted attacks. We find that the ten theoretical metrics capture two distinct aspects of robustness of metro networks. First, several metrics place an emphasis on alternative paths. Second, other metrics place an emphasis on the length of the paths. To account for all aspects, we standardize all ten indicators and plot them on radar diagrams to assess the overall robustness for metro networks. Overall, we find that Tokyo and Rome are the most robust networks. Rome benefits from short transferring and Tokyo has a significant number of transfer stations, both in the city center and in the peripheral area of the city, promoting both a higher number of alternative paths and overall relatively short path-lengths.

    Manila clam ( Ruditapes philippinarum) was monthly sampled from its benthic aquaculture area in Jiaozhou Bay from May 2009 to June 2010. The annual variations of major elemental composition, organic content, fatness and element ratio of Manila clam were examined. The element removal effect of clam farming in Jiaozhou Bay was analyzed based on natural mortality and clam harvest. The results indicated that the variation trend of carbon content in shell ( C shell) was similar to that in clam ( C clam). Such a variation was higher in summer and autumn than in other seasons, which ranged from 9.10 ± 0.13 to 10.38 ± 0.09 mmol g-1 and from 11.28 ± 0.29 to 12.36 ± 0.06 mmol g-1, respectively. Carbon content of flesh ( C flesh) showed an opposite variation trend to that of shell in most months, varying from 29.42 ± 0.05 to 33.64 ± 0.62 mmol g-1. Nitrogen content of shell ( N shell) and flesh ( N flesh) changed seasonally, which was relatively low in spring and summer. N shell and N flesh varied from 0.07 ± 0.009 to 0.14 ± 0.009 mmol g-1 and from 5.46 ± 0.12 to 7.39 ± 0.43 mmol g-1, respectively. Total nitrogen content of clam ranged from 0.50 ± 0.003 to 0.76 ± 0.10 mmol g-1 with a falling tend except for a high value in March 2010. Phosphorus content of clam ( N clam) fluctuated largely, while phosphorus content of shell ( P shell) was less varied than that of flesh ( P flesh). P shell varied from 0.006 ± 0.001 to 0.016 ± 0.001 mmol g-1; while P flesh fluctuated between 0.058 ± 0.017 and 0.293 ± 0.029 mmol g-1. P clam ranged from 0.015 ± 0.002 to 0.041 ± 0.006 mmol g-1. Carbon and nitrogen content were slightly affected by shell length, width or height. Elemental contents were closely related to the reproduction cycle. The removal amounts of carbon, nitrogen and phosphorus from clam harvest and natural death in Jiaozhou Bay were 2.92×104t, 1420 t and 145 t, respectively. The nutrient removal may aid to reduce the concentrations of nitrogen and phosphorus

    The northern part of the Philippine fault zone, in Luzon, corresponds to a complex braided system of left-lateral strike-slip faults. The NW oriented main active branch, which emerges from the Philippine Sea, splits into an array of north striking splays responsible for the tectonic evolution of the Central Cordillera. This complex fault pattern has favored local stress field variations. Strike-slip basins have evolved in this framework along or in the vicinity of the main splays of the Philippine fault. Apart from the classical pull-apart tectonics on a releasing fault termination, overlap, or bend, we describe other mechanisms such as the strike-slip tilting or the warping of a strip limited by two strike-slip faults. The strike-slip basins are good recorders of the evolution of the Philippine fault system. Those located along the north striking cordilleran faults individualized in late early Pliocene to Pleistocene time when the present-day Philippine fault initiated, but their main control is the fault shape acquired in upper middle Miocene time. The recent tectonic evolution of the fault system is best recorded in central Luzon, where the active basins trace an asymmetrical V shape, with the longest branch trending NE parallel to the East Luzon Trough, and the shortest one trending NW related to the Philippine fault. Both the fault pattern and the basin distribution demonstrate the influence of the Benham Rise in the tectonic evolution of Luzon. The structural setting is interpreted as the result of an early Miocene collision event between the Benham Rise and the eastern margin of Luzon, and subsequent inception of the NW striking strand of the Philippine fault. The present locations of the basins result from the interaction between the structural heritage and the present-day regional plate motion.

    Outbreaks involving the Asian genotype Chikungunya virus (CHIKV) caused over one million infections in the Americas recently. The outbreak was preceded by a major nationwide outbreak in the Philippines. We examined the phylogenetic and phylogeographic relationships of representative CHIKV isolates obtained from the 2012 Philippines outbreak with other CHIKV isolates collected globally. Asian CHIKV isolated from the Philippines, China, Micronesia and Caribbean regions were found closely related, herein denoted as Cosmopolitan Asian CHIKV (CACV). Three adaptive amino acid substitutions in nsP3 (D483N), E1 (P397L) and E3 (Q19R) were identified among CACV. Acquisition of the nsP3-483N mutation in Compostela Valley followed by E1-397L/E3-19R in Laguna preceded the nationwide spread in the Philippines. The China isolates possessed two of the amino acid substitutions, nsP3-D483N and E1-P397L whereas the Micronesian and Caribbean CHIKV inherited all the three amino acid substitutions. The unique amino acid substitutions observed among the isolates suggest multiple independent virus dissemination events. The possible biological importance of the specific genetic signatures associated with the rapid global of the virus is not known and warrant future in-depth study and epidemiological follow-up. Molecular evidence, however, supports the Philippines outbreak as the possible origin of the CACV.

    Outbreaks involving the Asian genotype Chikungunya virus (CHIKV) caused over one million infections in the Americas recently. The outbreak was preceded by a major nationwide outbreak in the Philippines. We examined the phylogenetic and phylogeographic relationships of representative CHIKV isolates obtained from the 2012 Philippines outbreak with other CHIKV isolates collected globally. Asian CHIKV isolated from the Philippines, China, Micronesia and Caribbean regions were found closely related, herein denoted as Cosmopolitan Asian CHIKV (CACV). Three adaptive amino acid substitutions in nsP3 (D483N), E1 (P397L) and E3 (Q19R) were identified among CACV.

    The structure and tectonic history of the Sulu Sea are described on the basis of seismic reflection data combined with the findings of onshore and offshore geological studies, and the results of ODP Leg 124 drilling. Closing of a hypothetical Mesozoic proto-South China Sea associated with the formation of oceanic crustal splinters in the late Eocene followed by southward subduction and, in turn, progressive collision of the north Palawan continental terrane with the micro-continental Borneo plate since the middle Miocene, resulted in the formation of the structurally complex Sulu-Borneo collision belt. The latter comprises north Sabah, southern and central Palawan, and the northwest Sulu basin. Fracturing of the Borneo micro-continental plate into the Sulu and Cagayan ridges initiated the opening of the southeast Sulu basin during the late Oligocene through the early Miocene. Collision of the north Palawan continental terrane with Cagayan Ridge in the late early Miocene and oblique collision of these blocks with the central Philippines resulted in the still ongoing closing of the southeast Sulu basin since the middle or late Miocene. Closing of the southeast Sulu basin began with the formation of an oceanic crustal slab.

    The offshore area of northwest Palawan, Philippines, contains a number of provenexploration plays. These include • pinnacle reefs developed on Nido carbonate platforms (e.g. Nido, Matinloc, Cadlao);• a seaward horst block reef fairway with large pinnacle reefs (e.g. Malampaya—Camago trend);• early Miocene Galoc Clastic Unit turbidites (e.g. Octon, Galoc); and• four-way dip closures (e.g. West Linapacan, Octon). The recent discovery by Fletcher Challenge Petroleum at Calauit Field has shown a potentialexploration play in deep-water Nido Limestone turbidites. The traditional and, to date, only economically productive play in northwest Palawan has been the Nido Limestone reefs. This paper presents a review of the old play types and presents new untested play types. These new play types include • pre-Nido syn-rift plays;• pre-Nido marine turbidite play: and• mid-Miocene reefs. It also presents new insights into factors controlling reef development on the carbonate platforms where four reef types are now recognized. The Galoc Clastic Unit turbidite play is discussed and new play fairways presented.

  13. The skin whitening industry in the Philippines.

    Skin whitening is a big and booming industry in many developing countries. Its popularity owes mainly to post-colonial, internalized racism. This study examines whether government intervention is necessary and more efficient than market-driven approaches in addressing the health risks and harms associated with skin whitening. We gathered empirical data on the quality and quantity of health-related information about skin whiteners with a multi-stage probability sample of consumers in two cities in the Philippines (n=110; α=0.05). Regardless of their socio-demographic characteristics, we find that cognitive biases and information asymmetries build and sustain consumers' trust in manufacturers and distributors of skin whiteners while, paradoxically, breeding uncertainties over the integrity of these products. The results are product adulteration and misbranding, leading to pricing advantages for toxic whiteners over safer products. This has impeded regulatory efficacy. We recommend anchoring government intervention in transaction cost-reduction, containing the externalities of skin bleaching, and institutionalizing third party partnerships. Failure to do so would leave consumers extremely vulnerable to the forces of supply and demand that favor toxic whiteners, particularly in a market where voluntary collective action is difficult to organize.

    A project using the entertainment media was developed to promote responsible sexual behavior of young people in the Philippines. Music videos by Lea Salonga and the group Menudo were used to sell the message of responsible sexual behavior and to encourage counseling for discussing and solving their problems. There were 2 parts: a commercial phase to make the songs hits with a social message, and an institutional phase to develop counseling centers and a telephone counseling service. The project was planned to use cost sharing with private corporations, and over $1.4 million was obtained from corporate sponsorship. Surveys after the project began showed that 92% of the young people heard the song and 90% like it. Over 51% stated that it had an impact on them, 44% talked to their parents about it, and 25% asked for contraceptive information. Of those surveyed, 83% said they were aware of the telephone counseling service offered. There were over 8,000 calls answered by the counselors. The lessons learned from this project were that the use of professionals and top materials can help gain corporate support and access to the media. By planning to use cost sharing and cost recovery methods, a challenge is presented to the staff to use creative approaches. The use of the right celebrities can aid visibility, credibility and excitement to the project. This approach can be a useful method to promote a social message and get the interest of the private sector.

    of rocks are associated with westward subduction along the Philippine Trench where presumably deep oceanic sediments with little or no continental crustal component have been subducted. The absence of continental crust below the arc in the Northern Luzon and Babuyan segments has been suggested by several groups of researchers. This, together with the fact that metasomatized ultramafic nodules (probably of mantle origin) in disequilibrium with their Batan host lavas (but with similar {87Sr }/{86Sr } and {[La}/{Sm] CN} ratios to the host rocks), suggests that upper level assimilation (AFC processes) does not appear to be the major influence on the geochemical signatures. A collision zone between the upper crustal block of Eastern China and Taiwan and the Manila Trench has been recorded in the northern section of the arc (Taiwan). Sediments have also been shown to decrease in thickness along the South China Sea basin nearly parallel to the Manila Trench from north to south. The sediment source region is most probably Taiwan, and perhaps Eastern China. This latitudinal in variation sediment thickness may explain the crustal signature related to both geochemical and age parameters. We suggest that this crustal input has taken place via subduction of sediment rich in a crustal component.

    The large estuary that the River Po forms at its confluence into the Adriatic Sea comprises a multitude of transitional environments, including coastal lagoons. This complex system receives the nutrients transported by the River Po but also its load of chemical contaminants, which may pose a substantial (eco)toxicological risk. Despite the high ecological and economic importance of these vulnerable environments, there is a substantial lack of information on this risk. In light of the recent amendments of the European Water Framework Directive (2013/39/EU), the present study investigated the sediment contamination of six coastal lagoons of the Po delta and its effects on Manila clams (Ruditapes philippinarum), exposed in situ for 3 months. Sediment contamination and clam bioaccumulation of a wide range of chemicals, i.e. trace metals (Cd, Cr, Ni, Hg, Pb, As), polybrominated diphenyl ethers (PBDEs), alkylphenols (APs), organochlorine compounds (PCBs, DDTs), polycyclic aromatic hydrocarbons (PAHs) and organotins (TPhT, TBT), suggested a southward increase related to the riverine transports. Where the River Po influence was more direct, the concentrations of contaminants were higher, with nonylphenol and BDE-209 exceeding sediment quality guidelines. Biometric indicators suggested the influence of contamination on organism health; an inverse relationship between PBDEs in sediments and clam condition index has been found, as well as different biota-sediment accumulation factors (BSAFs) in the lagoons.

    Suppression subtractive hybridization (SSH) was used to identify alterations in gene transcription of the manila clam Ruditapes philippinarum after exposure to 5μg/L 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) for 15days. The ability to accumulate BDE-47 in digestive gland and gill was also evaluated in order to provide information for food safety. Analysis of tissue extracts indicated that digestive gland had the higher BDE-47 levels (12,463.1±1334.8 ng/g d.w.) compared to gill (6368.6±738.7ng/g d.w.) after a 15-day exposure period. Forward and reverse SSH libraries were made from pooled digestive glands of R. philippinarum, from which 75 high quality sequences were obtained by BLAST analysis. The expression of 39 genes with significant homology (E-value<10(-5)) out of the 75 sequences was investigated by quantitative RT-PCR. Among the 39 genes, 27 genes were found up-regulated while 12 genes were found down-regulated after the BDE-47 exposure. The 39 genes were involved in cellular cycle, cytoskeleton, substance and energy metabolism, stress response, innate immunity and cell signaling and transport which were extensively discussed. This study provides a preliminary basis for studying the response of marine bivalves upon exposure to PBDEs in terms of regulated gene expression.

    In this study, the method of divergent selection was employed to test the larval and juvenile growth performance within a full-sib family of Manila clam Ruditapes philippinarum. The 10% largest and 10% smallest clam individuals (on the basis of shell length) of a full-sib family were selected as parents for the fast and slow growing lines, respectively. The difference in shell length was significant among the three lines (fast, control, and slow) tested. The sequence of shell length were fast line > control line > slow line. The responses to selection, realized heritability, and genetic gain were 0.06%-0.81%, 0.04%-0.47% and 0.58%-18.89% in the fast direction, respectively; and were 0.14%-1.27%, 0.08%-0.73%, and 0.31%-49.03% in the slow direction, respectively. The results suggested that there was a large portion of additive genetic variance affecting the growth in the full-sib family. Selection in the fast direction within the full-sib family would greatly improve the growth of R. philippinarum.

    The protein expression profiling in clam haemocytes and plasma in response to Perkinsus olseni was addressed. Adult Manila clams from a P. olseni-free bed were experimentally challenged with parasite zoospores to analyse immune response. In another experiment, the effects of longer term infection were assessed in adult clams collected from a P. olseni-affected bed, by comparing moderate to very heavily infected clams with non-infected ones. Haemocyte and plasma proteins were separated by two-dimensional electrophoresis; spot patterns were qualitatively compared between treatments within each experiment and the spots indicating differential protein expression associated with P. olseni challenge or with field infection were processed for protein identification. Fifteen clam proteins (four in haemocytes and eleven in plasma) of which expression was markedly affected by P. olseni were identified. Some of the identified proteins have a well-known role in clam immune response against the parasite, such as lysozyme and lectins. Rho GTPase-activating protein 6 could be a marker of resistance against P. olseni, which should be further studied. © 2016 John Wiley & Sons Ltd.

    Intertidal organisms, especially the sessile species, often experience long-term periodic air exposure during their lives. Learning the biochemical and physiological responses of intertidal organisms to long-term periodic air exposure and the relationship to duration of air exposure provides insight into adaptation to this variably stressful environment. We studied the Manila clam, Ruditapes philippinarum, an important species in world aquaculture, as a model to evaluate survival, growth, lipid composition, oxygen consumption, oxidative damage, and antioxidant enzyme activity in relation to the duration of air exposure in a long-term (60 days) laboratory study of varying durations of periodic emersion and re-immersion. Our results show: (1) clams undergoing a longer period of air exposure had lower survival and growth compared to those given a shorter exposure, (2) levels of oxidative damage and activities of antioxidant enzymes were higher in all air exposure treatments, but did not increase with duration of air exposure, and (3) the content of docosahexaenoic acid increased with duration of air exposure. Our results can largely be interpreted in the context of the energy expenditure by the clams caused by aerobic metabolism during the daily cycle of emersion and re-immersion and the roles of docosahexaenoic acid against oxidative stress.
