    The Highly Frustrated Magnetism 2006 (HFM 2006) conference took place on 15-19 August 2006 at the Icho Kaikan of Osaka University, Osaka, Japan. This conference was the third one of the series, following the first one in Waterloo, Canada (HFM 2000) [1] and the second one in Grenoble, France (HFM 2003) [2]. The HFM 2006 conference was held as a satellite of the International Conference on Magnetism (ICM 2006) held on 20-25 August 2006 in Kyoto, Japan. The conference attracted 191 participants from all over the world. The number of participants of the HFM conference series has been increasing steadily, from about 80 participants for HFM 2000 and about 120 participants for HFM 2003, demonstrating that highly frustrated magnetism is a rapidly growing area for research in condensed matter physics. The HFM 2006 conference consisted of four plenary talks by H Takagi, F Mila, P Mendels and B D Gaulin, 18 invited presentations and about 120 poster presentations from all areas of frustrated magnetism. In the evening on the 18th of August, a special session about 'the kagome story' was given by M. Mekata, where participants learned about the history of early-day research on frustrated magnetism and the origin of the word 'kagome' (see the picture below). Kagome lattice in a traditional Japanese woven basket Kagome lattice from a Japanese traditional woven bamboo basket. During the conference period, many stimulating discussions were held both inside and outside the conference room. The subjects covered in the conference included: Quantum frustrated magnetism and spin liquids Novel ordering of geometrically frustrated magnets Itinerant frustrated systems and novel superconductivity Spin glasses and random magnets Frustration effect on the coupling to lattice, orbital and charge degrees of freedom Exotic phenomena induced by macroscopic degeneracy Field effect on frustrated magnetism etc. This special issue of Journal of Physics: Condensed Matter is devoted to the proceedings

    The physical, chemical, and dewatering characteristics of 19 bottom sediments from Osaka Bay, Japan, have been analyzed to aid in the development of sediments in the coastal bay area. The sediments in the east near Osaka Port were highly polluted from the influence of human activities and were difficult to dewater. These sediments were composed of fine particles, low in pH, zetapotential, and initial settling rate, and were high in ignition loss, metal concentrations, compression volume, specific resistance, cake water content, and drying index. However, the sediments near Akashi Channel showed the reverse where they are affected by strong tidal current. A correlation analysis has been made of all the parameters. There are significant relationships between all the dewatering parameters. Therefore, sediments difficult to dewater by gravity settling are also difficult to dewater by vacuum filtration and solar evaporation. Sediments containing fine particles and pollutants are difficult to dewater. Several forms of pollutants can occur in the sediments.

    Human adenovirus (HAdV) strains isolated from respiratory specimens of 139 children between 2008 and 2015 were analyzed with the intent of evaluating the endemic situation of HAdV infections in Osaka, Japan. The cases increased in spring and winter, and the infections were confirmed mainly in children aged ≤ 5 years, comprising 91.9% of the total population examined. Molecular typing of the isolates revealed that the most common types belonged to HAdV-B and HAdV-C, and a case of co-infection with HAdV-C1 and HAdV-C2 was confirmed. The median age of HAdV-E cases were higher than that of HAdV-B and -C cases. These results revealed age and seasonal distribution of respiratory infections caused by HAdVs in children in Osaka, and indicate that the majority of children might have acquired immunity through infection with endemic HAdVs before school age.

    Perfluoroalkyl acids (PFAAs) including perfluoroalkyl sulfonates (PFSAs) and perfluoroalkyl carboxylates (PFCAs) were analyzed in sediment samples taken from Ajifu Waterway in Osaka city, from Osaka Bay, and from Kagoshima Bay, as well as in fifteen seawater samples collected from Osaka Bay and coastal waters of Western Japan. In all sediment samples, only PFCAs were detected, and the highest concentration was determined in Ajifu Waterway, where ΣPFAA was 58990 ng kg(-1) dry weight. The total concentrations of PFAAs in sea water samples ranged between the limit of quantification and 53.4 ng L(-1), and perfluorohexanoic acid was the most prevalent and had the highest concentration of 37 ng L(-1). The changes in the patterns and concentrations of PFAAs in Osaka Bay and coastal waters of Western Japan indicate that the PFAAs in surface waters are influenced by sources from Keihanshin Metropolitan Area, mainly the Yodo River basin, and the dilution effect which naturally occurs during their transport to the Pacific Ocean.

    Live benthic foraminiferal assemblages from surface sediment in Osaka Bay collected in 1999 were analyzed to characterize the distribution of the modern foraminiferal assemblages. Foraminiferal assemblages were compared with those of previous studies to document environmental changes in Osaka Bay over the past 50 years. Sixty-one species of foraminifera belonging to 37 genera were recognized from the 1999 surface sediment samples. An agglutinated assemblage containing Trochammina hadai and Eggerella advena is dominant in the inner part of the bay and is related to eutrophication. The foraminiferal assemblage in areas deeper than about 20 m is composed of Eggerella advena, Ammonia beccarii forma A, and Pseudorotalia gaimardii. This assemblage may be influenced by the large clockwise Okinose Circulation Current which extends throughout the western bay. Foraminiferal assemblages in Osaka Bay have changed dramatically during the last 50 years. The Trochammina hadai-Eggerella advena assemblage became established in the inner part of the bay, reflecting eutrophication that progressed from the 1960s through the 1970s. This assemblage became dominant in 1983, and typically dominated the inner part of the bay. From 1983 to 1999, however, the abundance of taxa belonging to this assemblage decreased greatly following implementation of 1973 Osaka City bylaws that restricted wastewater discharge. Changes in benthic assemblages such as the decrease of Ammonia beccarii forma A and increase of Eggerella advena have occurred in response to decreased incidence of red tides, and floral change in the species that cause these tides. The results of this study demonstrate that the abundance and distribution of benthic foraminifers in Osaka Bay are intimately related to environmental changes related to the urbanization of coastal areas. ?? by the Palaeontological Society of Japan.

    Contaminations in sediments by polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs were investigated at 44 sites in Osaka Bay, Japan. Concentrations of total PAHs and alkylated PAHs were in the range 6.40-7800 ng/g dry weights and 13.7-1700 ng/g dry weights, respectively. The PAH concentrations tended to be higher along the shoreline in the vicinities of big ports, industrialized areas, and densely populated regions such as the cities of Osaka and Kobe. The major sources appeared to be pyrogenic or both pyrogenic and petrogenic at most of the sites. PAH concentrations were remarkably high at a site near Kobe, where the concentrations of dibenzo(a,h)anthracene and benzo(g,h,i)perylene exceeded the effects-range-medium concentration and eight PAHs were above the corresponding effects-range-low concentrations. Those PAHs may have been derived from the great fire associated with the large earthquake in 1995.

    There is a high possibility of reoccurrence of the Tonankai and Nankai earthquakes along the Nankai Trough in Japan. It is very important to predict the long-period ground motions from the next Tonankai and Nankai earthquakes with moment magnitudes of 8.1 and 8.4, respectively, to mitigate their disastrous effects. In this study, long-period (>2.5 s) ground motions were predicted using an earthquake scenario proposed by the Headquarters for Earthquake Research Promotion in Japan. The calculations were performed using a fourth-order finite difference method with a variable spacing staggered-grid in the frequency range 0.05 0.4 Hz. The attenuation characteristics ( Q) in the finite difference simulations were assumed to be proportional to frequency ( f) and S-wave velocity ( V s) represented by Q = f · V s / 2. Such optimum attenuation characteristic for the sedimentary layers in the Osaka basin was obtained empirically by comparing the observed motions during the actual M5.5 event with the modeling results. We used the velocity structure model of the Osaka basin consisting of three sedimentary layers on bedrock. The characteristics of the predicted long-period ground motions from the next Tonankai and Nankai earthquakes depend significantly on the complex thickness distribution of the sediments inside the basin. The duration of the predicted long-period ground motions in the city of Osaka is more than 4 min, and the largest peak ground velocities (PGVs) exceed 80 cm/s. The predominant period is 5 to 6 s. These preliminary results indicate the possibility of earthquake damage because of future subduction earthquakes in large-scale constructions such as tall buildings, long-span bridges, and oil storage tanks in the Osaka area.

    It is known that the aerosol distribution in Asia is complicated due to the increasing emissions of anthropogenic aerosols in association with economic growth and natural dust significantly varied with the seasons. Therefore it is clear that local spatially and temporally resolved measurements of atmospheric aerosols in Asian urban city are necessary. Since Osaka, Kobe, Kyoto, and Nara are located in very close each others (all cities are included in around 70×70 km2 area). The population of the region is around 13 millions including neighbor prefectures, accordingly air quality in this region is slightly bad in comparison with the remote area. Furthermore, in recent years, Asian dusts and anthropogenic small particles some times transported from China and cover these cities throughout year. DRAGON (Distributed Regional Aerosol Gridded Observation Network) is a project of dense sun/sky radiometer network in the urban area. The DRAGON-West Japan field campaign was performed over Osaka and neighbor cities with 7 AERONET instruments from March to end of May in 2012. As results, DRAGON measurements indicate small differences among the values of AOT over Osaka region.

    A coprological survey was performed at a slaughterhouse in Osaka, Japan, from 2004 to 2007 on 129 pigs reared in 8 prefectures, and on 213 cattle reared in 21 prefectures. Eimeria spp., Trichuris suis, Ascaris suum and Metastrongylus spp. infections were found in 52 (40.3%), 32 (24.8%), 19 (14.7%) and 3 pigs (2.3%), respectively, while Eimeria spp., Capillaria bovis and Trichuris sp. infections were detected in 163 (76.5%), 15 (7.0%) and 8 cattle (3.8%), respectively. Our results suggest that environmentally resistant oocysts and eggs of parasites could be widespread at the farms examined.

    We analyzed the travel-related health problems in persons returning to Japan from overseas. Data were extracted retrospectively for all patients visiting the infectious diseases department of Osaka City General Hospital, Osaka, Japan, between July 2012 and September 2013. There were 209 sick returning travelers during the period of the study. The median age of the subjects was 34.3 years, and the subjects consisted of 133 tourists (63.6%), 39 business travelers (18.7%), 17 expatriates (8.1%), 14 volunteer workers (6.7%), and four persons who visited friends and relatives (1.9%). The most visited destinations were Asia (n=162, 77.5%), including East Asia (n=26, 12.4%), Southeast Asia (n=116, 55.5%), South Asia (n=25, 12.0%), Central Asia (n=3, 1.4%), and Africa (n=30, 14.3%). The most commonly diagnosed diseases were gastrointestinal tract infection (n=81, 38.8%), dengue fever (n=26, 12.4%), and animal bites (n=26, 12.4%). Twenty-nine patients (13.8%) were hospitalized, mainly for dengue fever and gastrointestinal tract infection.

    Mortality for childhood cancer has declined in Osaka, as well as all over Japan, since the 1970s, but whether this decline can be explained by trends of incidence or survival of childhood cancer has not been examined. A total of 5960 malignant tumors diagnosed between 1973 and 2001 in children <15 years of age were registered at the Osaka Cancer Registry in Japan. The time trends for childhood cancer were analyzed over 29 years for incidence and 20 years for survival. Leukemia was the most common among childhood cancer for both sexes and accounted for one-third of all cases. The age-standardized annual incidence rate of all tumors was highest in 1988-1992: 155.1 per million for males and 135.9 for females. Five-year survival for all tumors improved from 50.1% in 1978-1982 to 73.0% in 1993-1997 for males and from 52.3% to 76.3% for females. Thus, the constant decline in mortality in childhood cancer was primarily due to improved survival between the 1970s and 1980s and reduced incidence after the 1990s.

    The survival gap between adolescents and young adults (AYAs) with hematological malignancies persists in many countries. To determine to what extent it does in Japan, we investigated survival and treatment regimens in 211 Japanese AYAs (15-29 years) in the Osaka Cancer Registry diagnosed during 2001-2005 with hematological malignancies, and compared adolescents (15-19 years) with young adults (20-29 years). AYAs with acute lymphoblastic leukemia (ALL) had a poor 5-year survival (44%), particularly young adults (29% vs. 64% in adolescents, p = 0.01). Additional investigation for patients with ALL revealed that only 19% of young adults were treated with pediatric treatment regimens compared with 45% of adolescents (p = 0.05). Our data indicate that we need to focus on young adults with ALL and to consider establishing appropriate cancer care system and guidelines for them in Japan.

    Human parechovirus (HPeV) infects humans early in life and typically causes asymptomatic or mild diseases such as gastrointestinal and respiratory illness but sometimes leads to more serious consequences in neonates and young infants. In 2014, we detected HPeV from 38 patients by real-time reverse transcription-PCR in Osaka City, Japan, and 33 HPeV strains were genotyped based on their VP1 sequences. HPeV genotype 3 (HPeV-3) was the most prevalent and accounted for 22 cases (66.7%) followed by nine HPeV-1 (27.3%), one HPeV-2 (3.0%) and one HPeV-4 (3.0%). Phylogenetic analysis revealed that detected HPeV-3 strains were divided into three genetically distinct groups. One was characterized by a novel single amino acid deletion mutation at the N terminus of the 2A protein as well as the VP1 sequence, whereas the others were closely related to HPeV-3 strains detected in Japan in either 2008 or 2011. These HPeV-3 groups were detected from patients with various symptoms including three myositis cases. Recent papers have demonstrated that HPeV-3 was the aetiological agent for epidemic myalgia exclusively among adults from Yamagata Prefecture in Japan. Here, we provide clinical details and episodes of three myositis patients including an adult and two children in Osaka City, Japan. Our results suggest that HPeV-3 is a causative agent of myositis not only in adults but also in children.

    The occurrence and diversity of barnacles attached to the hulls of two intercontinental bulk carriers were studied at the port in Osaka Bay, Japan, to assess the potential risk of introduction of exotic species to the inner part of the bay. Barnacles were sampled from the bulbous bows, near the midship draft marks, and around the propeller posts and rudders. Twenty-two species were found, with 14 of these not previously recorded in Osaka Bay, including four species not previously recorded elsewhere in Japan. From an assessment of environmental similarity between Osaka Bay and native ranges, of the 14 species, Elminius modestus and Amphibalanus variegatus were considered to have the highest risk of introduction to the inner part of the bay.

    Osaka City has the highest tuberculosis (TB) notification rates in Japan. In the period 1999–2003, the TB control programme was strengthened, and the Stop TB Strategy was implemented to reduce the number of notified cases. The objective of this study was to assess the effect of these control activities in Osaka City, including the implementation of directly observed treatment (DOT), by analysing TB surveillance and routinely collected data. We reviewed the surveillance data of all sputum smear-positive pulmonary tuberculosis (PTB) cases registered in the Osaka City Public Health Office from 2001 to 2008 and data collected from the routine TB programme. The DOT implementation rate increased from 0% in 2001 to 68% in 2008 for smear-positive PTB cases of the general public and to 61% for all PTB cases of the homeless. The proportion of smear-positive PTB cases that had treatment failure and default combined, declined from 8.0% (52 of 650) in 2001 to 3.6% (20 of 548) in 2006. The proportion of cases among the homeless with previous treatment declined from 28% in 2001 to 15% in 2008. The proportion of cases with multidrug resistant-TB (MDR-TB) among those without previous treatment declined from 1.7% in 2001 to 0.9% in 2008. It is logical that reduction in the failure and default rate would lead to the reduction of cases with previous treatment and TB transmission, including resistant TB, therefore to the reduction of MDR-TB rates.

    The distributions of 15 nitrated polycyclic aromatic hydrocarbons (NPAHs) in sediments collected at 44 sites throughout Osaka Bay, Japan were examined. The highest total NPAHs, with a concentration of 1949ng/kg dry weight, were detected near the city of Amagasaki. Some sites near the cities of Osaka, Kishiwada, sand Sakai registered ng/kg levels of NPAHs, but individual NPAH concentrations were relatively lower than those in previous studies. The sources were estimated using principal component analysis, and NPAHs were derived from exhaust gases of automobiles and industries at some sites. However, our results suggest that it is difficult to estimate the source, especially in coastal areas near big cities and large industrial areas, because the generation pathways between parent polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs are slightly different, and the ratio of PAHs and NPAHs could not be accurately reflect the characters of sources in sediments especially at coastal areas with large-scale industrial zones.

    The Great East Japan Earthquake occurred on March 11, 2011. Tokyo and Osaka, which are located 375 km and 750 km, respectively, from the epicenter, experienced tremors of 5.0 lower and 3.0 seismic intensity on the Japan Meteorological Agency scale. The Great East Japan Earthquake was the fourth largest earthquake in the world and was accompanied by a radioactive leak at a nuclear power plant and a tsunami. In the aftermath of a disaster, some affected individuals presented to mental health facilities with acute stress disorder (ASD) and/or post-traumatic stress disorder (PTSD). However, few studies have addressed mental stress problems other than ASD or PTSD among the general public immediately after a disaster. Further, the effects of such a disaster on residents living at considerable distances from the most severely affected area have not been examined. This study aimed to prospectively analyze the effect of a major earthquake on the prevalence of insomnia among residents of Tokyo and Osaka. A prospective online questionnaire study was conducted in Tokyo and Osaka from January 20 to April 30, 2011. An Internet-based questionnaire, intended to be completed daily for a period of 101 days, was used to collect the data. All of the study participants lived in Tokyo or Osaka and were Consumers' Co-operative Union (CO-OP) members who used an Internet-based food-ordering system. The presence or absence of insomnia was determined before and after the earthquake. These data were compared after stratification for the region and participants' age. Multivariate analyses were conducted using logistic regression and a generalized estimating equation. This study was conducted with the assistance of the Japanese CO-OP. The prevalence of insomnia among adults and minors in Tokyo and adults in Osaka increased significantly after the earthquake. No such increase was observed among minors in Osaka. The overall adjusted odds ratios for the risk of insomnia post-earthquake versus pre

    In recent years, the coastal marine ecosystems have been deteriorated by the human activities and fisheries. One of the causes of this deteriorating situation is due to the increase of nutrient fluxes caused by the fertilizers and wastewater through the surface water and groundwater discharges from the residential and agricultural areas into coastal areas. In recent studies, it is recognized that the groundwater which contains nutrients can have a significant influence on coastal ecosystems. Submarine groundwater discharge (SGD) consists of terrestrial fresh groundwater and recirculated seawater which circulate across the aquifer-ocean interface. Recirculating seawater, which often constitutes a large portion of the total SGD, is an important component as it transports not only salt but also other chemicals from the ocean to the aquifer. Near the shore, seawater recirculation across the interface is driven primarily by tidal oscillations, waves and density variations between fresh groundwater and seawater. Recent numerical simulations show the formation of water circulations in the aquifers near the shoreline owing to the tidal oscillations. However, these calculation results do not compare with a field observation and are not necessarily an enough verification. The objective of this study is to evaluate the SGD mechanism in the Omaehama, Osaka bay under the influence of tidal effects. The developed numerical model was verified by comparing the results with the observed SGD in the Osaka bay. The study area is located in the coast of Omaehama, Osaka, Bay, Nishinomiya citiy, Japan. The automated seeepage meters with diameter of 500mm and piezometer with diameter of 13mm were installed to evaluate water dynamics below the beach slop. Electric conductivity of the pore water were also observed to evaluate the terrestrial groundwater among SGD duaring one tidal cycle. The numerical model is based on the groundwater flow equation for saturated-unsaturated fluid flow and

    Background In 2013, an unusually high incidence of biliary tract cancer among current or former workers of the offset color proof printing department of a printing company in Osaka, Japan, was reported. The purpose of this study was to examine whether distance from the printing factory was associated with incidence of biliary tract cancer and whether incident biliary tract cancer cases clustered around the printing factory in Osaka using population-based cancer registry data. Methods We estimated the age-standardized incidence ratio of biliary tract cancer according to distance from this printing factory. We also searched for clusters of biliary tract cancer incidence using spatial scan statistics. Results We did not observe statistically significantly high or low standardized incidence ratios for residents in each area categorized by distance from the printing factory for the entire sample or for either sex. The scan statistics did not show any statistically significant clustering of biliary tract cancer incidence anywhere in Osaka prefecture in 2004–2007. Conclusions There was no statistically significant clustering of biliary tract cancer incidence around the printing factory or in any other areas in Osaka, Japan, between 2004 and 2007. To date, even if some substances have diffused outside this source factory, they do not appear to have influenced the incidence of biliary tract cancer in neighboring residents. PMID:26902168

    In 2013, an unusually high incidence of biliary tract cancer among current or former workers of the offset color proof printing department of a printing company in Osaka, Japan, was reported. The purpose of this study was to examine whether distance from the printing factory was associated with incidence of biliary tract cancer and whether incident biliary tract cancer cases clustered around the printing factory in Osaka using population-based cancer registry data. We estimated the age-standardized incidence ratio of biliary tract cancer according to distance from this printing factory. We also searched for clusters of biliary tract cancer incidence using spatial scan statistics. We did not observe statistically significantly high or low standardized incidence ratios for residents in each area categorized by distance from the printing factory for the entire sample or for either sex. The scan statistics did not show any statistically significant clustering of biliary tract cancer incidence anywhere in Osaka prefecture in 2004-2007. There was no statistically significant clustering of biliary tract cancer incidence around the printing factory or in any other areas in Osaka, Japan, between 2004 and 2007. To date, even if some substances have diffused outside this source factory, they do not appear to have influenced the incidence of biliary tract cancer in neighboring residents.

    The first upsurge of enterovirus D68 (EV-D68), a causative agent of acute respiratory infections (ARIs), in Japan was reported in Osaka City in 2010. In this study, which began in 2010, we surveyed EV-D68 in children with ARIs and analyzed sequences of EV-D68 strains detected. Real-time PCR of 19 respiratory viruses or subtypes of viruses, including enterovirus, was performed on 2,215 specimens from ARI patients (<10 years of age) collected between November 2010 and December 2015 in Osaka City, Japan. EV-D68 was identified in 18 enterovirus-positive specimens (n = 4 in 2013, n = 1 in 2014, and n = 13 in 2015) by analysis of viral protein 1 (VP1) or VP4 sequences, followed by a BLAST search for similar sequences. All EV-D68 strains were detected between June and October (summer to autumn), except for one strain detected in 2014. A phylogenetic analysis of available VP1 sequences revealed that the Osaka strains detected in 2010, 2013, and 2015 belonged to distinct clusters (Clades C, A, and B [Subclade B3], respectively). Comparison of the 5' untranslated regions of these viruses showed that Osaka strains in Clades A, B (Subclade B3), and C commonly had deletions at nucleotide positions 681-703 corresponding to the prototype Fermon strain. Clades B and C had deletions from nucleotide positions 713-724. Since the EV-D68 epidemic in 2010, EV-D68 re-emerged in Osaka City, Japan, in 2013 and 2015. Results of this study indicate that distinct clades of EV-D68 contributed to re-emergences of this virus in 2010, 2013, and 2015 in this limited region.

    Candida species are clinically important causes of bloodstream infections because their mortality is very high. Given that some species of Candida are azole-resistant, identifying the distributions of Candida species could facilitate the formulation of an appropriate empirical antifungal therapy. It has been shown that the distribution varies depending on the continent, country, city, and hospital. In this paper, we describe the distributions of species in hospitals in northern Osaka, Japan. We evaluated blood culture results obtained from six tertiary hospitals in the northern Osaka area between 2004 and 2011. We also obtained comorbidity information from the patients' hospital medical records. Kaplan-Meier curves were drawn to compare the risk of death related to the different species. Of the 165 cases of candidemia confirmed by blood culture, 66% were male and the mean age was 62 years (range = 0-96). Overall, Candida albicans comprised 70 cases (43%), followed by Candida parapsilosis with 36 cases (22%), Candida glabrata with 25 cases (15%), Candida tropicalis with 11 cases (7%), Candida krusei with 10 cases (6%), and other Candida species with 13 cases (8%). C. tropicalis had higher associated mortality than other species, although it was not statistically significant. C. albicans was the most frequently isolated species, but the proportion of non-albicans Candida species was not negligible. The relatively high frequency of non-albicans Candida species distinguished the Japanese distribution from other areas. This characteristic distribution may have important implications when formulating an empirical antifungal therapy for Japanese clinical practice.

    Because tissue transplantation (TTx) has not been familiar to the general public or even to medical staffs in Japan, awareness of TTx is very important to increase tissue donation. Our primary aim was to describe the current status of awareness of TTx in medical staffs and in the general public around Osaka. Between July 2014 and February 2015, 1015 general public citizens, 203 medical staff members working in emergency hospitals, and 168 cardiothoracic surgeons were invited to complete a letter or web-based survey through the use of a self-designed questionnaire. In the general public citizens, only 25.1% knew about TTx, whereas 54.7% knew about organ transplantation (OTx); 25.4% agreed to donate their organs or tissues and 17.3% disagreed to donate their organs or tissues. In medical staff members working in emergency hospitals, 58.7% knew about TTx; 82.3% agreed to support organ or tissue procurement and 10.8% disagreed to do so. Among cardiothoracic surgeons, 78.7% knew about TTx; 33.2% had used valve or vascular homografts and 57.4% wanted to use them if possible. According to these surveys, public awareness of TTx has been less than that of OTx, but willingness to donate tissue was not different from that of donating organs. Awareness of TTx in medical staffs in emergency hospitals was higher but still not satisfactory. To increase tissue donation in Japan, the East and West Japan Tissue Transplant Network, in collaboration with cardiothoracic surgeons, should make more effort to carry out dissemination and awareness regarding TTx to the general public and to medical staffs.

    SummaryWe used δ 34S values and chemical compositions of groundwater to investigate the influence of sulfate reduction and sulfide oxidation processes in a confined aquifer system in the northeastern Osaka Basin (NEOB), central Japan. Shallow confined groundwater (<100 m) in the basin is recharged mainly from mountainous areas to the north, and flows south and southwest through the aquifer system. Anion composition of the groundwater is dominated by HCO3- throughout the basin. However, concentrations of redox-sensitive species such as dissolved oxygen, NO3-, Fe 2+, and Mn 2+ show that groundwater conditions become increasingly anoxic along the flowpaths. Moreover, SO 4/(SO 4 + 2HCO 3) molar ratios decrease with increasing δ 34S along the flowpaths, which demonstrates that sulfate is reduced in the NEOB aquifer system. Groundwater with both high total dissolved solids and high SO 4 content was observed mainly in areas down-flow from faults. Because of the high SO 4 content, the anion composition of this groundwater cannot be adequately explained by a simple sulfate reduction process. A Rayleigh distillation model with ɛ = -20‰, which allows for sulfide oxidation within marine sediments in proximity to faults, explains the chemistry of all groundwater samples, including those with high SO 4 content. The model demonstrates that 76% of initial sulfate is reduced at maximum, and that reduced SO42- content is up to 48.5 mg/L after sulfide oxidation in the NEOB aquifer system.

    "Radiation Fair" has been held in summer vacation season in August for more than 10 years in Osaka, the largest city of western Japan, for the purpose of public education and information transfer of radiation and radiation-related technology. We distributed questionnaires to the visitors for recent 3 years to inquire their status toward radiation and irradiated products including irradiated potatoes as well as impression toward the displays. According to the survey results, more than 60% of the kids visitors were satisfied with this exhibition as informative, more than half of the older visitors (16 years old and upward) indicated that they recognized the word of "radiation" when they were at elementary school and the most significant sources of this information were school lessons and the mass media. Consumer's image toward radiation seems to shift to more "positive" when correct knowledge about radiation is given. More than half of consumers did not know "irradiated potatoes" but the percentage indicating that irradiated potatoes was definitely hazardous was less than 10%.

    Sapovirus (SaV) is a causative agent of gastroenteritis in humans in both sporadic cases and outbreaks. During the period from January 2005 to August 2014, SaV was detected in 30 (5.9%) of 510 gastroenteritis outbreaks in Osaka City, Japan using real-time RT-PCR. Seasonal distribution of SaV-associated outbreaks revealed an increase during the 2011-2012 season and the highest frequency of outbreaks during the 2012-2013 season. Genotyping analysis based on the capsid region demonstrated that the most common genotype was GI.2 (36.7%), in which the strains were closely related. The comparison of complete capsid gene sequences with 18 GI.2 strains (7 strains in this study and 11 from GenBank) between 1990 and 2013 showed that GI.2 strains were classified into at least three genetic clusters (1990-2000, 2004-2007, and 2008-2013) with chronologically unique amino acid residues and accumulation of mutations in the predicted P domain, suggesting the one of the causes of emergence and spread of GI.2 strains. This study will also be helpful for understanding the evolutionary mechanism of the SaV genome. © 2015 Wiley Periodicals, Inc.

    During the 2009-2010 season, a significant numerical increase of genotype GII.2 norovirus (NoV)-associated outbreaks was observed in Osaka City, Japan. The most common genotype in that season was GII.2 (44.6%), followed by GII.4 (39.2%). Mostly, GII.2 strains were associated with outbreaks in children and with person-to-person contact. The National Infectious Disease Surveillance Center reported that GII.2 NoV infections were widespread in Japan in that season. Comparative phylogenetic analysis of RNA-dependent RNA polymerase (RdRp) and capsid sequences revealed that this GII.2 epidemic resulted from two genetic strains. The first, GII.2p2 strains, had an identical genotype in the RdRp and capsid genes. GII.2p2 strains in the 2009-2010 season were a different genetic cluster from the strains of spring 2004, the previous epidemic of GII.2 NoV, but showed no unique amino acid change. The second, GII.2 chimera virus (GII.2p16), had GII.16 RdRp and GII.2 capsid genotypes, suggesting prior recombination at the junction of ORF1 and ORF2. GII.2p16 strains had four significant amino acid changes in the P2 subdomain, suggesting antigenic changes. Before the 2009-2010 season, GII.2 chimera viruses had been observed only sporadically. This spreading of GII.2p16 strains in the 2009-2010 season might be the first epidemic of GII.2 chimera virus. This study revealed that the NoV epidemic in the 2009-2010 season differed considerably from the prior season, when GII.4 was predominant. Furthermore, GII.2 strains persisted in human populations by drastic recombination and gradual accumulation of mutations, indicating a prevalent pattern of non-GII.4 genotypes with genetic evolution.

    Several studies of sex differences in lung cancer survival have been reported. However, large-size population-based studies based on long-term observation are scarce. We investigated long-term trends in sex differences in lung cancer survival using population-based cancer registry data from Osaka, Japan. We analyzed 79 330 cases from the Osaka Cancer Registry (OCR) diagnosed between 1975 and 2007. We calculated 5-year relative survival in the six periods (1975-1980, 1981-1986, 1987-1992, 1993-1997, 1998-2002 and 2003-2007). To estimate the trends in sex differences in lung cancer survival throughout the study period, we applied a multivariate excess hazard model to control for confounders. The proportion of adenocarcinoma (ADC) and 5-year relative relative survival have increased for both sexes. Sex differences in lung cancer survival have widened over the period, especially in ADC and since the late 1990s. The excess hazard ratio of death within 5 years for males was 1.19 (95% CI: 1.16-1.21), adjusting for period at diagnosis, histologic type, stage, age group and treatment. We reported that females have better prognosis in lung cancer than males and the sex differences in lung cancer survival have become wider in Osaka, Japan. This can be partly explained by the sex differences in the proportions of histologic type and stage. Further studies considering other factors that influence sex differences in lung cancer survival are needed.

    Hereditary angioedema (HAE) with deficiency of C1 inhibitor (C1-INH) is an autosomal-dominant disease characterized by recurrent episodes of potentially life-threatening angioedema. The objective is to study the incidence of HAE among patients who visit the emergency department.This was a 3-year prospective observational screening study involving 13 urban tertiary emergency centers in Osaka prefecture, Japan. Patients were included if they met the following criteria: unexplained edema of the body, upper airway obstruction accompanied by edema, anaphylaxis, acute abdomen with intestinal edema (including ileus and acute pancreatitis), or asthma attack. C1-INH activity and C4 level were measured at the time of emergency department admission during the period between July 2011 and June 2014.This study comprised 66 patients with a median age of 54.0 (IQR: 37.5-68.3) years. Three patients were newly diagnosed as having HAE, and 1 patient had already been diagnosed as having HAE. C1-INH activity levels of the patients with HAE were below the detection limit (<25%), whereas those of non-HAE patients (n = 62) were 106% (IQR: 85.5%-127.0%) (normal range, 70%-130%). The median level of C4 was significantly lower in the patients with HAE compared with those without HAE (1.2 [IQR: 1-3] mg/dL vs 22 [IQR: 16.5-29.5] mg/dL, P < 0.01) (normal range, 17-45 mg/dL).Three patients with undiagnosed HAE were diagnosed as having HAE in the emergency department during the 3-year period. If patients have signs and symptoms suspicious of HAE, the levels of C1-INH activity and C4 should be measured.

    The aim of this study was to investigate the clinical and endocrinological characteristics of adrenal incidentalomas in Osaka region, Japan. The study was a multicenter retrospective analysis of 150 patients with adrenal incidentalomas who underwent radiographic and endocrine evaluations between 2005 and 2013. Most adrenal incidentalomas were discovered by computed tomography (77.0%) and the rest were identified by abdominal ultrasonography (14.6%), magnetic resonance imaging (4.2%), or positron emission tomography (4.2%). Adrenal incidentalomas were more frequently localized on the left side than on the right. The average diameter of tumors was 21 ± 11 mm. On endocrinological evaluation, 14 patients were diagnosed with primary aldosteronism (9.3%), 10 with subclinical Cushing's syndrome (6.7%), 7 with pheochromocytoma (4.7%), 7 with Cushing's syndrome (4.7%), 2 with both subclinical Cushing's syndrome and primary aldosteronism (1.3%), and 110 with non-functioning tumors (73.3%). Patients with functioning tumors were significantly younger and had larger tumor diameters than those with non-functioning tumors. Except for hypertension, complications were comparable between patients with functioning and non-functioning tumors, including the presence of glucose intolerance, cardiovascular disease, and dyslipidemia. In conclusion, a higher prevalence of primary aldosteronism was observed compared with a previous report. Complications were comparable between patients with functioning and non-functioning tumors, including the frequencies of glucose intolerance, cardiovascular disease, and dyslipidemia. Long-term follow-up is required in patients with non-functioning tumors because the frequency of complications, such as glucose intolerance, cardiovascular disease, and dyslipidemia, was equal to that in patients with functioning tumors.

    We determined the elemental compositions of stream water of the Neyagawa river systems in the Osaka Plain, Japan. The river water were enriched in Na+ and HCO3-in the southeast part of the Osaka Plain and in Ca2+ and HCO3- in the upper stretches of the Neyagawa river systems. These results indicate that these ionic compositions are derived mainly from geological inputs from the drainage basins. The river water were rich in Na+ and Cl- in Hiranogawa, Hiranogawa canal, the middle part of Neyagawa and the upper part of Furukawa. This ionic composition is largely attributable to artificial effect. Major ionic compositions of river water showed temporal variation in the center of the Osaka Plain. Tidal effect was shown in this area. The distribution of major ions and trace elements had a relationship to the factor such as geological, tidal, and artificial effect in each area. The origin of Na+, Cl-, SO42-, NO3-, Rb and Ni was artificial activity and tide. Geological input was mainly the provenance of HCO3-, Ca2+, Mg2+, Si and Ba. The concentrations of B, Li and Sr varied same as HCO3- and Ca2+ in the southeast part of the Osaka Plain. Moreover, the temporal variations of these elements showed the same trend as Na+and Cl-under the tidal effect area. These results suggest that it is possible to distinguish that tidal effect is reaching or not to the area by using the concentration ratios of B, Li and Sr to Na+.

    Although organ procurement has been regulated by The Organ Transplantation Law (brain-dead donors since 1997, donors after cardiac death since 1979), there has been no law or governmental procurement network (except for cornea) in Japan. Since the late 1980s, some university hospitals have developed original banks. Finally, in 2001 guidelines for tissue procurement were established by The Japanese Society of Tissue Transplantation and Japan Tissue Transplant Network (JTTN) to coordinate tissue harvesting. Five tissue banks were joined to the tissue transplant network (skin in one, heart valves in two, and bone in two). As the number of tissue banks is small, each bank cooperates on procurement, but cannot cover the entire country. With regard to skin transplantation, only one skin bank-The Japan Skin Bank Network (JSBN), which is located in Tokyo-has organized skin procurement. Therefore, it has been difficult to procure skin in areas distant from Tokyo, especially around Osaka. In order to improve such a situation, a tissue bank collaborating with the JSBN was established at The Medical Center for Translational Research (MTR), Osaka University Hospital in April 2008. The bank has played a role in skin procurement center in western Japan and supported procurement and preservation at the time of the skin procurement. Between April 2008 and September 2009, the bank participated in eight tissue procurements in the western area. In the future, the bank is planning to procure and preserve pancreatic islets and bones. Moreover, there is a plan to set up an induced pluripotent stem cells center and stem cell bank in MTR. This tissue bank may play a role to increase tissue procurement in Japan, especially in the western area. .

  16. Modelling of wave propagation and attenuation in the Osaka sedimentary basin, western Japan, during the 2013 Awaji Island earthquake

    On 2013 April 13, an inland earthquake of Mw 5.8 occurred in Awaji Island, which forms the western boundary of the Osaka sedimentary basin in western Japan. The strong ground motion data were collected from more than 100 stations within the basin and it was found that in the Osaka Plain, the pseudo velocity response spectra at a period of around 6.5 s were significantly larger than at other stations of similar epicentral distance outside the basin. The ground motion lasted longer than 3 min in the Osaka Plain where its bedrock depth spatially varies from approximately 1 to 2 km. We modelled long-period (higher than 2 s) ground motions excited by this earthquake, using the finite difference method assuming a point source, to validate the present velocity structure model and to obtain better constraint of the attenuation factor of the sedimentary part of the basin. The effect of attenuation in the simulation was included in the form of Q(f) = Q0(f/f0), where Q0 at a reference frequency f0 was given by a function of the S-wave velocity, Q0 = αVS. We searched for appropriate Q0 values by changing α for a fixed value of f0 = 0.2 Hz. It was found that values of α from 0.2 to 0.5 fitted the observations reasonably well, but that the value of α = 0.3 performed best. Good agreement between the observed and simulated velocity waveforms was obtained for most stations within the Osaka Basin in terms of both amplitude and ground motion duration. However, underestimation of the pseudo velocity response spectra in the period range of 5-7 s was recognized in the central part of the Osaka Plain, which was caused by the inadequate modelling of later phases or wave packets in this period range observed approximately 2 min after the direct S-wave arrival. We analysed this observed later phase and concluded that it was a Love wave originating from the direction of the east coast of Awaji Island.

    Noroviruses (NVs) are the major cause of food- and waterborne nonbacterial gastroenteritis in Japan. Between April 2002 and March 2003, a total of 111 fecal specimens from 40 outbreaks of acute nonbacterial gastroenteritis in Osaka City, Japan were subject to NV detection. Seventy-two samples (64.9%) from 31 outbreaks (77.5%) were NV positive by a real time reverse transcription (RT)-PCR assay. To further determine the genotype of individual NV strains, we sequenced the capsid N-terminal/shell (N/S) domain of some representative strains from each outbreak. The 51 NV strains detected in this study were segregated into 15 genotypes (6 in genogroup I and 9 in genogroup II), and GII/5 genotype NV was a dominant outbreak genotype.

    Inter-station cross-correlation functions estimated using continuous ambient noise or microtremor records were used to extract the seismic wave propagation characteristics of the Osaka sedimentary basin, Japan. Temporary continuous observations were conducted at 15 sites in the Osaka basin between 2011 and 2013. The data were analyzed using seismic interferometry. The target period range was 2-8 s. Cross-correlations between all of the possible station pairs were calculated and stacked to produce a year-long data set, and Rayleigh wave signals in the vertical and radial components and Love wave signals in the transverse component were identified from the results. Simulation of inter-station Green's functions using the finite difference method was conducted to check the performance of the current three-dimensional velocity structure model. The measured time lag between the observed and theoretical Green's functions was less than 2 s for most station pairs, which is less than the wave period of interest in the target frequency range. Group velocity tomography was applied to group delay times estimated by means of multiple filter analysis. The estimated group velocities for longer periods of 5-8 s exhibited spatial variation within the basin, which is consistent with the bedrock depth distribution; however, the group velocities for shorter periods of 2-3 s were almost constant over the studied area. The waveform and group velocity information obtained by seismic interferometry analysis can be useful for future reconstruction of a three-dimensional velocity structure model in the Osaka basin.[Figure not available: see fulltext.

    ABSTRACT This study aimed to investigate intestinal helminth infection in stray dogs in Osaka Prefecture by surveying coprological samples from dogs captured from 2006–2011. Of 212 fecal samples collected, overall prevalence of infection was 39.2%. The most common species was Toxocara canis (25.0%), followed by Trichuris vulpis (8.0%), Spirometra erinaceieuropaei (3.3%), Taeniidae (2.4%), Ancylostoma caninum (1.9%) and Toxascaris leonine (0.5%). In the molecular analysis, all of the taeniid eggs were negative for Echinococcus multilocularis and were identified as other taeniid species (e.g., Taenia pisiformis). Our results suggest that stray dogs remain important infection reservoirs of zoonotic parasites in Osaka Prefecture. Therefore, control of stray dogs is crucial for reducing the risk of public health problems due to parasitic infections. PMID:23774027

    Anthropogenic effects in both Osaka and Bangkok were evaluated to compare the relationships between subsurface environment and the development stage of both cities. Subsurface thermal anomalies due to heat island effects were found in both cities. The Surface Warming Index (SWI), the departure depth from the steady geothermal gradient, was used as an indicator of the heat island effect. SWI increases (deeper) with the magnitude of heat island effect and the elapsed time starting from the surface warming. Distributions of subsurface thermal anomalies due to the heat island effect agreed well with the distribution of changes in air temperature due to the same process, which is described by the distribution of population density in both Osaka and Bangkok. Different time lags between groundwater depression and subsidence in the two cities was found. This is attributed to differences in hydrogeologic characters, such as porosity and hydraulic conductivity. We find that differences in subsurface degradations in Osaka and Bangkok, including subsurface thermal anomalies, groundwater depression, and land subsidence, depends on the difference of the development stage of urbanization and hydrogeological characters.

    Detailed spatiotemporal patterns of the influence of urbanization-induced eutrophication on a metazoan benthic community in Osaka Bay were determined using sediment cores and fossil ostracode assemblages from the last 200 yr. Results suggest that total abundance of ostracodes increased in the middle part of the bay as a result of the increase of food supply by eutrophication. Conversely, abundance decreased in the inner bay, likely because of bottom-water hypoxia by eutrophication. The variation in species composition among sites within the bay may have decreased because of the effect of eutrophication, i.e., the dominance of species that prefer food-rich environments throughout all sites. These eutrophication-induced changes occurred around 1900 as a result of Japan's industrial revolution and around 1960 as a result of rapid urbanization, depending upon location. ?? 2007, by the American Society of Limnology and Oceanography, Inc.

    Cancer survivors are at excess risk of developing second primary cancers, but the precise level of risk in Japanese patients is not known. To investigate the risk of survivors developing second primary cancers, we conducted a retrospective cohort study using data from the Osaka Cancer Registry. The study subjects comprised all reported patients aged 0-79 years who were first diagnosed with cancer between 1985 and 2004 in Osaka and who survived for at least 3 months, followed-up through to December 2005. A metachronous second primary cancer was defined as any invasive second cancer that was diagnosed between 3 months and 10 years after the first cancer diagnosis. The main outcome measures were incidence rates per 100,000 person-years, cumulative risk and standardized incidence ratios (SIR) of second primary cancer. Metachronous second primary cancers developed in 13,385 of 355,966 survivors (3.8%) after a median follow-up of 2.5 years. Sex-specific incidence rates of metachronous second primary cancer per 100,000 person-years increased with age, and were higher among men than women (except for the 0-49 years age group), but these rates did not differ over the study period. The 10-year cumulative risk was estimated as 13.0% for those who first developed cancer at 60-69 years of age (16.2% for men, 8.6% for women). The SIR among those with first cancer diagnosed at 0-39 and 40-49 years of age were 2.13 and 1.52, respectively, in both sexes, whereas the SIR among cancers of the mouth/pharynx, esophagus and larynx were much higher than one as for site relationships. We showed that cancer survivors in Osaka, Japan, were at higher risk of second primary cancers compared with the general population. Our findings indicate that second primary cancers should be considered as a commonly encountered major medical problem. Further investigations are required to advance our understanding to enable the development of effective measures against multiple primary cancers. © 2012

    To evaluate progress in stomach cancer care in Japan since 1975. Population-based study of data extracted from the Osaka Cancer Registry. Population-based cancer registry in the area of Osaka Prefecture. All 66,032 cases diagnosed with a stomach cancer in Osaka Prefecture, Japan between 1975 and 2000 and registered in the Osaka Cancer Registry. 'Cure' fraction and median survival time for 'uncured' patients were estimated with multivariable mixture 'cure' model. The role played by age and stage at diagnosis on the changes in 'cure' parameters between 1975 and 2000 was evaluated. Missing stage was handled by multiple imputation approach. More than 50% of the patients diagnosed with a stomach cancer in 1996-2000 were estimated 'cured' from their cancer, corresponding to a 20% increase since 1975-1980. Median survival time for 'uncured' patients however remained unchanged at about 8 months. 'Cure' fraction was over 85% for localised tumours and 30% for regional tumours, but stayed as low as 2.5% for distant metastatic cancers. Improvement was underestimated by about 10% because of ageing of cancer patients. Changes in stage distribution explained up to 40% of the increase in 'cure' fraction among men and up to 13% in women. Overdiagnosis was unlikely to play any role in these patterns. 'Cure' fraction from stomach cancer dramatically increased in Osaka, Japan since 1975, partly because of earlier stage at diagnosis, but mostly due to improvement in treatment of stomach cancer patients. This study, based on a leading country in term of stomach cancer management, provides insightful results for other countries in which 'cure' fraction is usually much lower.

    We describe our laboratory investigation of a massive foodborne outbreak of gastrointestinal illness caused by enterotoxigenic Escherichia coli (ETEC) serotype O169:H41 that occurred during a 2-day traditional festival held in September 2012 in Osaka Prefecture, Japan. Of 126 customers who patronized a particular Japanese restaurant during the event, 102 developed symptoms of gastrointestinal disease. We isolated strains of ETEC serotype O169:H41 from 1 food sample and from fecal samples collected from 19 of 34 patients and 2 of 4 food handlers. Pulsed-field gel electrophoresis analysis of these isolates suggested that the foodborne pathogen that caused the diarrheal outbreak was a specific clone of ETEC serotype O169:H41. Based on these findings and our interviews with the restaurant owner and employees, we concluded that a likely cause of the outbreak was an overwhelmed capacity of the restaurant kitchen in terms of preservation of sanitary procedures during the festival and the inability of the restaurant staff to handle the relatively large quantity of food to ensure a lack of contamination with ETEC. Thus, we reconfirm that ETEC strains of serotype O169:H41 remain important causes of domestic foodborne outbreaks in developed countries, including Japan.

    Hand, foot, and mouth disease (HFMD) is an acute febrile illness characterized by fever; sore throat; and vesicular eruptions on the hands, feet, and oral mucosa. Until 2010, HFMD was predominantly associated with enterovirus (EV) A71 and coxsackievirus (CV) A16 in Japan. In 2011, CV-A6 emerged as a primary causative agent, causing the largest HFMD epidemic in Japan since 1981. Since then, CV-A6 has caused large HFMD epidemics every 2 years. The phylogenetic analysis of complete Viral Protein 1 (VP1) sequences revealed that most CV-A6 strains detected from 2011 to 2015 in Osaka City were classified into a different clade compared with CV-A6 strains detected from 1999 until 2009. The majority of CV-A6 strains detected in 2011 and most CV-A6 strains detected from 2013 to 2015 were mainly divided into two distinct genetic groups. Each epidemic strain carried unique amino acid substitutions in the presumed DE, EF, and GH loops of the VP1 protein that is exposed on the surface of the virion. There is a possibility that the appearance of substitutions on the surface of the virion and an accumulation of a susceptible population are significant factors in recent HFMD epidemics. © 2017 Wiley Periodicals, Inc.

    High-resolution foraminiferal analysis was conducted on a short sediment core from the inner part of Osaka Bay, Japan. Changes in foraminiferal assemblages were associated with eutrophication, bottom water hypoxia, and changes in red tide-causing algae. Before the 1920s, the calcareous species Ammonia beccarii, and the agglutinated species Eggerella advena and Trochammina hadai were rare, but calcareous foraminifers in general were abundant. Between the 1920s and 1940s, calcareous foraminifers decreased abruptly in abundance, while A. beccarii, E. advena and T. hadai increased in abundance. This faunal change corresponded in time to an increase in nutrients flowing in through the Yodo River, and bottom water hypoxia related to eutrophication. In the 1960s and 1970s, A. beccarii, E. advena and T. hadai further increased in abundance to become dominant, and many calcareous foraminifers nearly disappeared, corresponding to increasing bottom water hypoxia related to the rapid increase in discharged nutrients during the high economic growth period from 1953 to 1971. After the 1990s, A. beccarii decreased rapidly in abundance and E. advena and Uvigerinella glabra increased in abundance. The main components of red tide-causing algae changed from dinoflagellates to diatoms in the 1980s through 1990s, thus there was a change in the food supply to the benthos, which may have caused the increase in abundance of E. advena and U. glabra.

    An atmospheric pressure photoionisation (APPI) source for liquid chromatography/mass spectrometry (LC/MS) was applied to determine neonicotinoid pesticides in the aquatic environment. Dopant-assisted APPI was very effective in the ionisation of neonicotinoids. Neonicotinoids generated protonated molecules in APPI with high sensitivity, while adduct ions, such as sodiated molecules, were predominantly generated in conventional electrospray ionisation. The ionisation of neonicotinoids was confirmed by ultra-high-resolution MS. An analytical method coupled with solid phase extraction was developed for acetamiprid, clothianidin, dinotefuran, imidacloprid, nitenpyram, and thiamethoxam. Method detection limits were 0.47 to 2.1 ng L(-1) for six neonicotinoids. Dinotefuran was the most frequent and highest among the neonicotinoids examined in the aquatic environment in Osaka, Japan. The maximum concentration of dinotefuran was 220 ng L(-1). Given the toxicity of neonicotinoids for aquatic creatures, the concentrations observed here were substantially low. The change in concentrations was temporally coincident with the period of the neonicotinoid application. Although rapid photodegradation and some degradation products have been elucidated, the degradation products in the aquatic environment were not identified in the present study.

  8. Vertical differences in the composition of PM 10 and PM 2.5 in the urban atmosphere of Osaka, Japan

    Vertical differences in PM 10 and PM 2.5 suspended particles were investigated using a building in Osaka, Japan. Samples were collected on the roof of the building (200 m above ground level) and on the ground during 5-9 August and 2-6 December 2002. In addition to determination of sample mass, concentrations have been analyzed for major chemical components including elemental carbon (EC) and organic carbon (OC). Particle mass concentrations of the samples collected at 200 m were lower than those collected on the ground. "Others" species, defined as the difference between the total particle mass and the sum of the masses of the measured species, dominantly accounted for the vertical difference in mass concentrations in summer, whereas EC and OC were the major contributors in winter. Vertical profiles of relative humidity observed simultaneously indicated that relative humidity on the ground was higher than that at 200 m during the summer sampling period. Hence, it is likely that the higher concentrations of "others" species in the samples collected on the ground were probably caused by water having been absorbed by deliquescent components of the particles. Vertical temperature profiles during the winter sampling period suggested that stable meteorological conditions in winter resulted in the accumulation of primary particles, mainly emitted from vehicle exhaust, leading to the high concentrations of EC and OC on the ground.

    This study presents the results of a total diet study performed for estimating the dietary intake of polybrominated diphenyl ethers (PBDEs) in Osaka, Japan. The concentrations of 36 PBDEs were measured in samples from 14 food groups (Groups I-XIV). PBDEs were detected only in Groups IV (oils and fats), V (legumes and their products), X (fish, shellfish, and their products), and XI (meat and eggs) at concentrations of 1.8, 0.03, 0.48, and 0.01 ng g⁻¹, respectively. For an average person, the lower bound dietary intakes of penta- and deca-formulations were estimated to be 46 and 21 ng day⁻¹, respectively. A high proportion of the decabrominated congener (DeBDE-209) was observed in Group IV. To confirm the presence of DeBDE-209 in vegetable oils, an additional analysis was performed using 18 vegetable oil samples. Of these, seven contained ng g⁻¹ levels of DeBDE-209.

    Japan has been free from rabies since the 1950s. However, during the early 1900s several large-scale epidemics spread throughout the country. Here we investigate the dynamics of these epidemics between 1914 and 1933 in Osaka Prefecture, using archival data including newspapers. The association between dog rabies cases and human population density was investigated using Mixed-effects models and epidemiological parameters such as the basic reproduction number (R0), the incubation and infectious period and the serial interval were estimated. A total of 4,632 animal rabies cases were reported, mainly in dogs (99.0%, 4,584 cases) during two epidemics from 1914 to 1921, and 1922 to 1933 respectively. The second epidemic was larger (3,705 cases) than the first (879 cases), but had a lower R0 (1.50 versus 2.42). The first epidemic was controlled through capture of stray dogs and tethering of pet dogs. Dog mass vaccination began in 1923, with campaigns to capture stray dogs. Rabies in Osaka Prefecture was finally eliminated in 1933. A total of 3,805 rabid dog-bite injuries, and 75 human deaths were reported. The relatively low incidence of human rabies, high ratio of post-exposure vaccines (PEP) and bite injuries by rabid dogs (minimum 6.2 to maximum 73.6, between 1924 and 1928), and a decline in the proportion of bite victims that developed hydrophobia over time (slope = -0.29, se = 3, p < 0.001), indicated that increased awareness and use of PEP might have prevented disease. Although significantly more dog rabies cases were detected at higher human population densities (slope = 0.66, se = 0.03, p < 0.01), there were fewer dog rabies cases detected per capita (slope = -0.34, se = 0.03, p < 0.01). We suggest that the combination of mass vaccination and restriction of dog movement enabled by strong legislation was key to eliminate rabies. Moreover, the prominent role of the media in both reporting rabies cases and efforts to control the disease likely contributed to

    Monitoring of particulate matter near the surface is very important for the Earth environment, especially for human health and atmospheric environment. In Japan, concentration of suspended particulate matter (SPM), which is similar to PM10 but sharply cutting at 10 µm for the particle diameter, has been monitored since 1975 and is still now widely available for a daily monitoring. New PM2.5 rule was defined in 1997 in the United States, however the standard rule for PM2.5 monitoring has net yet made in Japan until 2009. As a result, the number of PM2.5 instruments is very limited in Japan. In practice the PM2.5 samplers are only used for scientific objects. Therefore estimation of PM2.5 over the wide area as possible as in Japan is an urgent issue. Anthropogenic small particles dominate the air especially over the urban areas because of local emissions by diesel vehicles and industries. The distribution of these particles is complicated due to the increasing emissions of sulfuric, nitric, carbonaceous and other aerosols in association with economic growth in East Asia. The goal of this work is to estimate PM2.5 distribution over the second big city Osaka in Japan based on satellite measurements. A brief processing line of PM2.5 estimation is as follows: 1. Acquirement of surface reflectance based on satellite data to retrieve aerosol characteristics. 2. Retrieval of columnar aerosol optical thickness (AOT) over Osaka from the fine resolved satellite image. 3. Vertical profile of aerosol concentration with NIES-LIDAR measurements. 4. Surface level aerosol optical depth (AOD) derived from columnar AOT and LIDAR dataset. 5. Estimation of PM2.5 based on the relationship between AOT, surface AOD, LIDAR and in-situ PM2.5 dataset simultaneously accumulated at AERONET/Osaka site since 2008. Note that, collocated data set of in situ PM2.5, AERONET AOT, and NIES-LIDAR data are available at Kinki University's AERONET site as mentioned in the above item 5. It is of interest

    Although it is important to assess the factors associated with traffic accident fatalities to decrease them as a matter of public health, such factors have not been fully identified. Using a large-scale data set of ambulance records in Osaka City, Japan, we retrospectively analyzed all traffic accident patients transported to hospitals by emergency medical service personnel from 2013 to 2014. In this study, prehospital death was defined as that occurring at the scene or in the emergency department immediately after hospital arrival. We assessed prehospital factors associated with prehospital death due to traffic accidents by logistic regression models. This study enrolled 28,903 emergency patients involved in traffic accidents, of whom 68 died prehospital. In a multivariate model, elderly patients aged ≥75 years (adjusted odds ratio [AOR] = 4.34; 95% confidence interval [CI], 2.29-8.23), nighttime (AOR = 2.75; 95% CI, 1.65-4.70), and type of injured person compared to bicyclists such as pedestrians (AOR = 9.58; 95% CI, 5.07-17.99), motorcyclists (AOR = 2.75; 95% CI, 1.21-6.24), and car occupants (AOR = 2.98; 95% CI, 1.39-6.40) were significantly associated with prehospital death due to traffic accidents. In addition, the AOR for automobile versus nonautomobile as the collision opponent was 4.76 (95% CI, 2.30-9.88). In this population, the factors associated with prehospital death due to traffic accidents were elderly people, nighttime, and pedestrian as the type of patient. The proportion of prehospital deaths due to traffic accidents was also high when the collision component was an automobile.

    High human herpesvirus 8 (HHV-8) seroprevalence has been reported in men who have sex with men (MSM) and are infected with HIV-1. However, it is unclear when they become infected with HHV-8. Thus, we conducted cross-sectional and longitudinal investigations of HHV-8 seroprevalence in HIV-1-infected individuals in Osaka, Japan. Plasma was collected from 121 individuals infected with HIV-1 and the anti-HHV-8 antibody titer was measured using an enzyme-linked immunosorbent assay with whole virus lysate. Subjects were classified into those with and without a past medical history of HHV-8-associated disease; the latter group was then classified into 3 subgroups based on the assumed route of HIV-1 infection: blood products, homosexual contact, and other routes. HHV-8 seroprevalence was compared among the groups and measured again approximately 3 years after the baseline measurement. The relationship between HHV-8 seropositivity and possible associated factors was also investigated. All 15 subjects with HHV-8-associated disease were seropositive, and all 11 subjects in the blood product group were seronegative. In the MSM group, 25 (30%) of 79 subjects were HHV-8 seropositive and, in the non-MSM group, 1 (6%) of 16 subjects was (p < 0.0001). In the longitudinal investigation, seroconversion was observed in 10 (19%) of 52 subjects in the MSM group who were seronegative at baseline. A correlation was observed between seroconversion and symptomatic syphilis (p = 0.0432). HHV-8 seropositivity and seroconversion rates were high in HIV-1-infected MSM, suggesting that, currently, HHV-8 is an epidemic pathogen in this population.

    To assess the association between favourable neurological outcome and hospital characteristics such as hospital volume and number of critical care centres (CCMCs) after out-of-hospital cardiac arrest (OHCA). This retrospective, population-based observational study conducted in Osaka Prefecture, Japan included adult patients with OHCA, aged ≥18 years who were transported to acute care hospitals between January 2005 and December 2012. We divided acute care hospitals into CCMCs or non-CCMCs, the latter of which were divided into the following three groups according to the annual average number of transported OHCA cases: low-volume (≤10 cases), middle-volume (11-39 cases), and high-volume (≥40 cases) groups. Random effects logistic regression models, with hospital treated as a random effect, were used to assess factors potentially associated with a favourable neurological outcome. A total of 44,474 patients were eligible. The proportions of favourable neurological outcome from OHCA were 0.9% (31/3559) in the low-volume group, 1.2% (106/9171) in the middle-volume group, 1.6% (222/14,007) in the high-volume group, and 4.3% (766/17,737) in the CCMC group (P<0.001). In the multivariable analysis, transport to CCMCs was significantly associated with favourable neurological outcome, compared with transport to non-CCMCs (adjusted odds ratio 1.63; 95% confidence interval, 1.60-1.66). Among the non-CCMC group, there was no significant relationship between hospital volume and favourable neurological outcome. In this population, transport of OHCA patients to CCMCs led to significantly higher one-month survival rates with favourable neurological outcome from OHCA, whereas no significant association was noted among the hospitals with different volumes.

    Continuous and simultaneous measurements of ammonia gas (NH3) and fine particulate ammonium (PM2.5NH4(+)) were performed in two distinct urban areas: Osaka, Japan, and Ho Chi Minh City (HCMC), Vietnam. Measurements were performed using a new online instrument. Two measurement periods were conducted during February 11-March 12, 2015 (cold period), and July 1-September 14, 2015 (warm period), at the urban site in Osaka, while 17 days of measurements, from May 21 to June 8, 2015, were conducted at the urban site in HCMC. The average NH3 concentration at the HCMC site was much higher than that at the Osaka site. The differences in the NH3 levels between the two cities are a result of their different emission sources. Traffic emission is a significant contributor to the NH3 levels within the urban area in Osaka. Conversely, the contribution of traffic emission to the NH3 levels in the HCMC urban area is negligible. With a population of around 8.5 million people living in the urban area of HCMC, the high NH3 level is due to human sources and poor waste management systems, especially because of the high temperature (30 °C) and dense population of the city (density up to 42,000 inhabitants per km(2)). In contrast to the NH3 levels, the highest PM2.5NH4(+) level occurred during the cold period at the Osaka site, and the average level at this site was higher than that at the HCMC site. The availability of atmospheric acids, low temperature, and high humidity facilitates the formation of ammonium. Our results indicate that NH3 plays a key role in secondary inorganic aerosol formation; therefore, it contributes to a significant amount of PM2.5 at the Osaka site. In contrast, the high levels of PM2.5 observed at the HCMC site are likely from road traffic emission, mainly motorcycles, rather than secondary inorganic aerosol formation.

    The authors have monitored polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in the coastal waters of Japan by using blue mussel (Mytilus edulis) as a biological indicator. The levels of both chemicals were surmised to closely relate to the number of municipal incinerators and the population densities in the cities adjoining the sampling location. The main contamination source in Osaka Bay, which is heavy polluted with PCDDs and PCDFs, was determined to be the fly ash from municipal waste incinerators based upon analytical results of blue mussel from Osaka Bay sediments, sediments from Osaka Bay, and sediments from a river, which is located near a typical urban municipal waste incinerator. However, there was a remarkable difference in congener profiles of PCDDs and PCDFs between the blue mussel and the fly ash, that is, the mussel mainly contained tetraCDDs and tetraCDFs with congener ratios of 56 {plus minus} 9.7% and 62 {plus minus} 6.0%, respectively, whereas the fly ash contained the higher chlorinated PCDDs and PCDFs as major congeners. In this study, the specific congener profiles of PCDDs and PCDFs in blue mussel were investigated from the point of view of their water solubilities.

    Few studies have evaluated the actual situations of emergency patients with self-inflicted injuries treated by emergency-medical-service (EMS) personnel. This study retrospectively reviewed population-based ambulance records in Osaka City, Japan, between January 2010 and December 2012, and enrolled emergency patients who suffered from self-inflicted injuries such as poisoning by drugs or gas, cutting/piercing skin, jumping from heights, hanging, and drowning. The endpoint was the annual incidence per 100,000 populations in Osaka City of emergency patients who presented with self-inflicted injuries by age and sex. Their outcomes including deaths at the scene and hospital arrival were also evaluated. During the study period, a total of 8,671 patients with 9,424 incidents of self-inflicted injuries were documented. The annual incidence of self-inflicted injuries was higher among women than men in the whole population and in the age group < =49 years (136.9 versus 82.6, and 214.8 versus 93.3, both Ps < 0.001), but it was inversely lower among women in the age group > =50 years (49.0 versus 68.9, P < 0.001). The total number of self-inflicted deaths was 1,564 (16.6 %), and the overall proportion of self-inflicted deaths was greater among men than women (32.2 % [1075/3340] vs. 7.5 % [451/6027], P < 0.001). The proportion of self-inflicted hanging was 76.7 % [1142/1489], followed by poisoning by carbon monoxide at 57.1 % [56/98] and jumping to death at 47.6 % [254/534]. Using large-scale EMS records, we investigated characteristics and outcomes of emergency patients with self-inflicted injuries treated by EMS personnel. Our findings suggested the gender paradox that the proportion of self-inflicted deaths was higher among men than women, while the proportion of non-fatal self-inflicted injuries was higher among women than among men, particularly in the group aged <=49 years.

    In previous studies we predicted future trends in cancer incidence for each prefecture in order to plan cancer control. Those predictions, however, did not take into account the characteristics of each prefecture. We therefore used the results of age-period-cohort analysis of incidence and mortality data of Osaka, and estimated the incidence and mortality of cancers at all sites and selected sites. The results reflect the characteristics of Osaka, which has and is expected to have large number of patients with liver cancer. We believe our results to be useful for planning and evaluating cancer control activities in Osaka. It would be worthwhile to base the estimation of cancer incidence and mortality in each prefecture on each population-based cancer registry.

    Objectives To evaluate the incidence and outcomes of self-harm from ambulance records. Design A retrospective, observational study. Setting Osaka City, Japan. Participants A total of 365 adolescents aged 10–19 years with emergency self-harm such as poisoning by drugs or gas, cutting skin, jumping from heights, hanging and drowning and treated by emergency medical service personnel from January 2010 through December 2012. Primary outcome measurements Incidence per 100 000 persons and outcome at the scene or hospital arrival by age and gender. Poisson regression models for incidence evaluation were used; reporting relative risks (RRs) and their 95% CIs. Results During the study period, a total of 425 self-harm events were documented in 365 adolescents. The incidence of self-harm increased significantly between the ages of 11 and 19 years, from 6.3 to 81.0 among boys and the ages of 12 and 19 years from 6.3 to 228.3 among girls, respectively (both p<0.001). Although there was no incidence difference between girls and boys in the group aged 11–14 years (RR 1.20; 95% CI 0.59 to 2.47), the incidence was significantly higher among girls than boys in the group aged 15–19 years (RR 4.18; 95% CI 3.20 to 5.45). The overall proportion of death by self-harm was 4.9%. The proportion of hospital admission and death by self-harm was higher among boys than among girls (38.6% vs 25.2%, p=0.016 and 14.8% vs 2.4%, p<0.001). Conclusions The incidence of emergency treatment for self-harm by adolescents increased with age and our findings also demonstrated the gender paradox. It would be necessary to establish active, gender-specific and comprehensive prevention strategies for adolescent self-harm, based on our findings showing the age and gender differences of self-harm among adolescents.

    Long-term recession of the Japanese economy during the 1990s led to growing social inequalities whilst health inequalities also appeared. The 2007 National Cancer Control Program of Japan targeted "equalisation of cancer medical services", but the system to monitor health inequalities was still inadequate. We aimed to measure socioeconomic inequalities in cancer survival in Japan. We analysed 13 common invasive, primary, malignant tumours diagnosed from 1993 to 2004 and registered by the population-based Cancer Registry of Osaka Prefecture. An ecological socioeconomic deprivation index based on small area statistics, divided into quintile groups, was linked to patients according to their area of residence at the time of diagnosis. We estimated one-, five-year and conditional five-year net survival by sex, period of diagnosis (1993-1996/1997-2000/2001-2004) and deprivation group. Changes in survival over time, deprivation gap in survival, and change in deprivation gap were estimated at one and five years after diagnosis using variance-weighted least square regression. The deprivation gap in one-year net survival was narrower than in five-year net survival and conditional five-year survival. During the study period, there was no change in deprivation gap, except for reductions for pancreas (men) and stomach (women), and an increase for lung (men) in one-year survival. We observed a linear association between level of survival and deprivation gap at five years and conditional five years, but no association at one-year survival. A wide deprivation gap in survival was observed in most of the adult, solid, malignant tumours, within the universal healthcare system in Japan. Overall, cancer survival improved in Osaka without any widening of inequalities in cancer survival in 1993-2004, shortly after the long-term economic recession and deep modifications in the social and work environments in Japan. The longer term impact of the recession on inequalities in cancer survival

    Several large cities and metropolitan areas, such as Osaka and Kobe are located in the Osaka basin, which has been filled by the Pleistocene Osaka group and the later sediments. The basin is surrounded by E-W trending strike slip faults and N-S trending reverse faults. The N-S trending 42-km-long Uemachi faults traverse in the central part of the Osaka city. The various geological, geophysical surveys, such as seismic reflection, micro tremor, gravity surveys and deep boreholes, revealed the complex basement configuration along the Uemachi faults. The depth of the basement is shallow in the central part of the Osaka plain. The Uemachi faults are locates on the western side of the basement upland. In the central part of the Uemachi faults, the displacement decreases. The fault model of the Uemachi faults consists of the two parts, the north and south parts. The NE-SW trending branch faults, Suminoe and Sakuragawa flexures, are also recognized based on various surveys around the central part. Kusumoto et al. (2001) reported that surrounding faults enable to form the basement configuration without the Uemachi faults model based on a dislocation model. Inoue et al. (2011) performed various parameter studies for dislocation model and gravity changes based on simplified faults model, which were designed based on the distribution of the real faults. The model was consisted of 7 faults including the Uemachi faults. In this study, the Osaka-wan fault was considered for the dislocation model. The results show the basement configuration including NE-SW branch faults. The basement configuration differs from the subsurface structure derived from the investigation of abundance geotechnical borehole data around the central part of the Uemachi faults. The tectonic developing process including the erosion and sea level change are require to understanding the structure from the basement to the surface of the Uemachi Fault Zone.

    Background Monitoring trends in lung cancer incidence and mortality is important for the evaluation of cancer control activities. We investigated recent trends in age-standardized incidence rates by histological type of lung cancer in Osaka, Japan. Methods Cancer incidence data for 1975–2008 were obtained from the Osaka Cancer Registry. Lung cancer mortality data with population data in Osaka during 1975–2012 were obtained from vital statistics. We examined trends in age-standardized incidence and mortality rates for all histological types and age-standardized incidence rates by histological type and age group using a joinpoint regression model. Results The age-standardized incidence rate of lung cancer levelled off or slightly increased from 1975–2008, with an annual percentage change of 0.3% (95% confidence interval [CI], 0.1%–0.4%) for males and 1.1% (95% CI, 0.9%–1.3%) for females, and the mortality rate decreased by 0.9% (95% CI, 1.2%–0.7%) for males and 0.5% (95% CI, 0.8%–0.3%) for females. The incidence rates of squamous cell carcinoma (SQC) and small cell carcinoma (SMC) significantly decreased for both genders, whereas that of adenocarcinoma (ADC) significantly increased among almost all age groups in both genders. Conclusions The incidence rates of SQC and SMC decreased with the decline in smoking prevalence, which probably explains the change in trends in the incidence rates of lung cancer from the mid-1980s. However, the reason for the increase in ADC remains unclear. Therefore, trends in incidence rates of lung cancer should be carefully monitored, especially for ADC, and the associations between ADC and its possible risk factors should be studied. PMID:27150013

    To investigate the association between the economic recession and the detection of advanced cases of pulmonary tuberculosis in Osaka city from 2007 to 2009. A repeated cross-sectional study. Osaka city has been the highest tuberculosis burden area in Japan. After the previous global financial crisis, the unemployment rate in Osaka prefecture has deteriorated from 5.3% in 2008 to 6.6% in 2009. During the study period, 3406 pulmonary tuberculosis cases were enrolled: 2530 males and 876 females; 1546 elderly cases (65 years and above) and 1860 young cases (under 65 years); 417 homeless cases and 2989 non-homeless cases. Patients' information included the sex, age, registry, health insurances, places of detection, sputum smear test results, patients' delay, doctors' delay and the grade of chest x-ray findings. They were statistically analysed between 2007 and 2008, two years before and just before the financial crisis, and between 2008 and 2009, just before and after the financial crisis. The total numbers of pulmonary tuberculosis cases were 1172 in 2007, 1083 in 2008 and 1151 in 2009. In health examinations for non-homeless people, higher number of cases in 2009 were sputum smear positive, had respiratory symptoms and showed advanced disease in chest x-rays than those in 2008, with a longer patients' delay. On the contrary, in health examination for homeless people, fewer cases of advanced pulmonary tuberculosis were found in 2009 than in 2008, with a shorter patients' delay. In clinical examinations, there was no trend towards a difference between non-homeless and homeless people. Although homeless people might be protected by public assistance, tuberculosis prevention and control need to be reinforced for the non-homeless population after the financial crisis.

    This study presents the levels of endocrine disrupting chemicals (EDCs) accumulated by Paraprionospio sp. from the Yodo River mouth, Osaka Bay. Since high concentrations of nonylphenol (NP), bisphenol A (BP), octylphenol (OP), 17β-estradiol (E2), and estrone (E1) have been measured in sediment from Osaka Bay, some bioaccumulation could be expected particularly in benthic animals. EDCs were analysed in Paraprionospio sp., a dominant benthic species in Osaka Bay. The results showed that Paraprionospio sp. had accumulated varying concentrations (wet weight; w.w.) of NP at 1,460-4,410 ng/g; BP at 22.5-39.6 ng/g; OP at 18.9-45.4 ng/g; E2 at 0.89-4.35 ng/g; and E1 at 0.06-2.50 ng/g. Accumulation of NP and OP were highest among the samples gathered in summer (July 2008), while concentrations of BP, E2, and E1 did not much differs within 3 years. EDC levels in Paraprionospio sp. were apparently greater than those in sediments showing bioaccumulation.

    We examined 33 rodents captured in an urban area of Osaka City, Japan for IgG antibodies against Seoul virus, severe fever with thrombocytopenia syndrome virus, hepatitis E virus, Leptospira interrogans, Yersinia pestis, spotted fever, typhus and scrub typhus group rickettsiae. We found that 3 (9.1%) and 1 (3.0%) of the 33 rodents had antibodies against L. interrogans and spotted fever group rickettsiae, respectively. DNAs of leptospires were detected from 2 of the 3 seropositive rodents, but DNA of rickettsia was not detected. Phylogenetic analysis and multiple locus sequence typing revealed that the 2 leptospires were L. interrogans belonging to a novel sequence type. There is a potential risk for acquiring rodent-borne zoonotic pathogens even in cities in developed countries.

    Trends in the prevalence rates of allergic symptoms in children have been discussed extensively, but it remains uncertain which symptoms increase or decrease over time owing to the lack of large-scale long-term consecutive cross-sectional studies performed on a representative population of children. To clarify the trends in the prevalence rates of allergic symptoms in Japanese children. Total population questionnaire surveys were conducted 15 times from 1975 to 2006 for all children attending public elementary schools in Osaka Prefecture, Japan, with the number of subjects ranging from 460,000 to 900,000. Parents of the children completed the questionnaire about allergic symptoms and other symptoms, including wheeze, physician-diagnosed atopic dermatitis, rhinitis, and itching eyes. Response rates were consistently over 90%. The prevalence of wheezing was constant until 1983, then increased from 1983 until 1993, then stabilized at about 4.4%. The lifetime prevalence of atopic dermatitis increased to 24% by 1993, and then decreased. The prevalence of rhinitis increased to 25% by 2003, whereas the prevalence of non-seasonal symptoms plateaued from 1993 on at 11% and vernal symptoms increased. The prevalence of itching eyes continued to increase to 21% in 2006, and vernal symptoms increased sharply. In Osaka Prefecture, Japan, the turning point when the prevalence of wheezing in schoolchildren had begun to increase was 1983. And the turning point when the increase in the prevalence of wheezing, atopic dermatitis, and non-seasonal allergic rhinitis turned to decrease or constant was 1993. The prevalence of rhinitis and itching eyes in spring was still increasing in 2006. © 2011 John Wiley & Sons A/S.

    Actual application of public-access automated external defibrillator (AED) pads to patients with an out-of-hospital cardiac arrest (OHCA) by the public has been poorly investigated. AED applications, prehospital characteristics, and one-month outcomes of OHCAs occurring in Osaka Prefecture from 2011 to 2012 were obtained from the Utstein Osaka Project registry. Patients with a non-traumatic OHCA occurring before emergency medical service attendance were enrolled. The proportion of AED pads that were applied to the patients' chests by the public and one-month outcomes were analysed according to the location of OHCA. In total, public-access AED pads were applied to 3.5% of OHCA patients (351/9978) during the study period. In the multivariate analyses, OHCAs that occurred in public places and received bystander-initiated cardiopulmonary resuscitation were associated with significantly higher application of public-access AEDs. Among the patients for whom public-access AED pads were applied, 29.6% (104/351) received public-access defibrillation. One-month survival with a favourable neurological outcome was significantly higher among patients who had an AED applied compared to those who did not (19.4% vs. 3.0%; OR: 2.76 [95% CI: 1.92-3.97]). The application of public-access AEDs leads to favourable outcomes after an OHCA, but utilisation of available equipment remains insufficient, and varies considerably according to the location of the OHCA event. Alongside disseminating public-access AEDs, further strategic approaches for the deployment of AEDs at the scene, as well as basic life support training for the public are required to improve survival rates after OHCAs.

    To investigate the association between the difficulty in hospital acceptance at the scene by emergency medical service (EMS) personnel and prehospital demographic factors and reasons for EMS calls. A retrospective, observational study. Osaka City, Japan. A total of 100 649 patients transported to medical institutions by EMS from January 2013 to December 2013. The definition of difficulty in hospital acceptance at the scene was EMS personnel making ≥5 phone calls to medical institutions until a decision to transport was determined. Multivariable analysis was used to assess the relationship between difficulty in hospital acceptance and prehospital factors and reasons for EMS calls. Multivariable analysis showed the elderly, foreigners, loss of consciousness, holiday/weekend, and night-time to be positively associated with difficulty in hospital acceptance at the scene. As reasons for EMS calls, gas poisoning (adjusted OR 3.281, 95% CI 1.201 to 8.965), trauma by assault (adjusted OR 2.662, 95% CI 2.390 to 2.966), self-induced drug abuse/gas poisoning (adjusted OR 4.527, 95% CI 3.921 to 5.228) and self-induced trauma (adjusted OR 1.708, 95% CI 1.369 to 2.130) were positively associated with the difficulty in hospital acceptance at the scene. Ambulance records in Osaka City showed that certain prehospital factors such as night-time were positively associated with difficulty in hospital acceptance at the scene, and reasons for EMS calls, such as self-induced drug abuse/gas poisoning, were also positive predictors for difficulty in hospital acceptance at the scene.

Patients who suffered OHCA, which occurred during exercise before the arrival of emergency medical service personnel, were included. The primary endpoint was one-month survival with a favourable neurological outcome after OHCA, defined using the Glasgow-Pittsburgh cerebral performance category scale 1 or 2. During the 7-year study period, 16,278 OHCAs were observed, and 52 (0.3%) occurred during exercise (male, n=41 [79%]; median age, 62 years). These incidents occurred mainly during running activities (n=14), followed by swimming (n=8), dance/social dance (n=6), tennis (n=4), and weight training (n=3). Within these exercise-related OHCAs, 47 (90%) were of cardiac origin, 45 (87%) were bystander-witnessed cardiac arrests, 49 (94%) received bystander-initiated cardiopulmonary resuscitation, and 30 (57%) received public-access defibrillation (PAD). Overall, 56% (29/52) had one-month survival with a favourable neurological outcome after OHCA, which was significantly higher among OHCAs of cardiac origin with PAD (77%, 23/30) than among those of cardiac origin without PAD (35%, 6/17) and among those of non-cardiac origin (0%, 0/5) (p<0.001). In Osaka, OHCAs during exercise represented a small subset of the overall OHCA burden, but occurred during a wide variety of exercise activities. Patients with OHCA of cardiac origin had a good prognosis, and PAD played an important role in improving patient outcomes. Copyright © 2017 Elsevier B.V. All rights reserved.

    Objectives To investigate the association between the difficulty in hospital acceptance at the scene by emergency medical service (EMS) personnel and prehospital demographic factors and reasons for EMS calls. Design A retrospective, observational study. Setting Osaka City, Japan. Participants A total of 100 649 patients transported to medical institutions by EMS from January 2013 to December 2013. Primary outcome measurements The definition of difficulty in hospital acceptance at the scene was EMS personnel making ≥5 phone calls to medical institutions until a decision to transport was determined. Multivariable analysis was used to assess the relationship between difficulty in hospital acceptance and prehospital factors and reasons for EMS calls. Results Multivariable analysis showed the elderly, foreigners, loss of consciousness, holiday/weekend, and night-time to be positively associated with difficulty in hospital acceptance at the scene. As reasons for EMS calls, gas poisoning (adjusted OR 3.281, 95% CI 1.201 to 8.965), trauma by assault (adjusted OR 2.662, 95% CI 2.390 to 2.966), self-induced drug abuse/gas poisoning (adjusted OR 4.527, 95% CI 3.921 to 5.228) and self-induced trauma (adjusted OR 1.708, 95% CI 1.369 to 2.130) were positively associated with the difficulty in hospital acceptance at the scene. Conclusions Ambulance records in Osaka City showed that certain prehospital factors such as night-time were positively associated with difficulty in hospital acceptance at the scene, and reasons for EMS calls, such as self-induced drug abuse/gas poisoning, were also positive predictors for difficulty in hospital acceptance at the scene.

    Following the heatstroke prevention guideline by the Ministry of Health, Labor, and Welfare of Japan, "safe hours" for heavy and light labor are estimated based on hourly wet-bulb globe temperature (WBGT) obtained from the three-member ensemble multi-period (the 2000s, 2030s, 2050s, 2070s, and 2090s) climate projections using dynamical downscaling approach. Our target cities are Tokyo and Osaka, Japan. The results show that most of the current climate daytime hours are "light labor safe,", but these hours are projected to decrease by 30-40 % by the end of the twenty-first century. A 60-80 % reduction is projected for heavy labor hours, resulting in less than 2 hours available for safe performance of heavy labor. The number of "heavy labor restricted days" (days with minimum daytime WBGT exceeding the safe level threshold for heavy labor) is projected to increase from ~5 days in the 2000s to nearly two-thirds of the days in August in the 2090s.

    Since the 1960s, Japan has experienced a striking increase in the incidence of colorectal cancer, now the second most common cancer in the country. Meanwhile, the management of colorectal cancer has changed dramatically with the implementation of, for example, screening, endoscopy and adjuvant chemotherapy. It is therefore of interest to monitor the long-term trends in population 'cure' in Japan. We analysed 33 885 colorectal cancer cases diagnosed between 1975 and 2000 in Osaka. We applied the multivariable mixture cure model to estimate cure fraction and median survival time (MST) for 'uncured' patients, by sex, age, stage, period at diagnosis and subsite. For colon cancer, the cure fraction increased by about 25%, while MST for the uncured was prolonged from 8 to 12 months. The cure fraction was 5% higher in men than in women, while MST was similar in both. The cure fraction also increased for localized and regional tumours. For rectal cancer, the cure fraction increased by about 25-30%, but remained lower than for colon cancer. From the late 1970s, the cure fraction for colorectal cancer increased dramatically due to better management of detection and care for colorectal cancer. This improvement was obtained at the cost of shorter MST for uncured patients.

    The levels of polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/PCDFs), and dioxin-like polychlorinated biphenyls (DL-PCBs) were determined in sediment samples from Can Gio, South Vietnam, and Osaka, Japan. Can Gio is known for the defoliation of its mangrove forests by aerial spraying with Agent Orange during the Vietnam War, whereas Osaka is renowned for a PCDD/PCDF pollution accident at a municipal solid-waste incinerator. For comparison, we also analyzed PCDD/PCDFs and DL-PCBs in sediment samples from Hue and Hanoi, Vietnam. The toxic equivalent quantity (TEQ) values in Can Gio were as high as those in Hue, Hanoi, and suburban areas of Osaka, but much lower than those in urban areas of Osaka. The proportion of the World Health Organization (WHO)-TEQ value contributed by 2,3,7,8-tetrachlorinated dibenzo-p-dioxin (TCDD) in Can Gio was approximately 30%, higher than the values in the other sample areas. These data suggest that residual sedimentary TCDD that originated from aerial spraying of Agent Orange occur in only low concentrations in Can Gio. The main contributors to WHO-TEQ values in Can Gio are natural sources, as in Hue. In contrast, commercial PCBs are the dominant contributors to WHO-TEQ values in Hanoi. In Osaka, agrochemicals used in rice cultivation, the incineration of solid waste, and commercial PCBs equally contributed to WHO-TEQ values at suburban locations. The dumping of incinerator-related materials and/or the inadequate management of commercial PCBs have resulted in significantly elevated WHO-TEQ values of 240-370 ng kg(-1)dw at urban locations in Osaka.

    A comparative study of polycyclic aromatic hydrocarbons (PAHs) associated with particulate matter (TSP) in the ambient air in an urban area in Ho Chi Minh City, Vietnam and in Osaka, Japan was carried out from 2005 to 2006. The objective of this study was to investigate the environmental levels, emission sources, seasonal variations and health risk of eleven PAHs in the two cities, especially Ho Chi Minh City where air pollution is becoming a serious concern. The results showed that the concentrations of TSP and total PAHs were significantly higher in Ho Chi Minh City than levels in Osaka. The concentrations of 5- and 6-ring PAHs (BeP, BbF, BkF, BaP, BghiP and InP) were much higher in TSP samples in Ho Chi Minh City than in Osaka, accounting for 82% and 51% of total PAHs, respectively. These PAHs are known to be highly carcinogenic and mutagenic in humans. Vehicular emission is suggested as one of the main pollution sources of PAHs in both cities. Motorcycles and gasoline automobiles are suggested as the main emission sources of PAHs in Ho Chi Minh City, whereas diesel automobiles are the primary source in Osaka. Seasonal variations of PAHs were observed in this study; higher concentrations of PAHs were found in the rainy season (May-December) and lower concentrations corresponded to the dry season (February-April) in Ho Chi Minh City, while higher concentrations of PAHs were observed in the winter (November-January) in Osaka. The number of sunshine hours was an important meteorological factor affecting seasonal variations of PAHs in Ho Chi Minh City, while the temperature was a main factor causing the variations of PAHs in Osaka. The high BaP equivalent concentration of 5- and 6-ring PAHs even in the ambient air is an alarming signal for harmfulness to human health and environmental quality in Ho Chi Minh City.

    At the ring cyclotron facility of the Research Center for Nuclear Physics (RCNP) Osaka University, Osaka, Japan a series of measurement campaigns had been continued with quasi mono-energetic neutron beams in November 2014. A 7Li target was bombarded with 100 and 300 MeV protons and the generated neutron beams were directed into a long time-of-flight tunnel at 0 and 25 degrees deflection angle with respect to the proton beam. At a distance of 41 m the cross section of the neutron beam was large enough for the illumination of square meter sized objects like extended range rem-counters. The research institutes SPring-8/RIKEN, Japan, and DESY, Germany, participated in this campaign for the calibration of 4 different types of active ambient dose rate monitors: LB 6411, LB 6411-Pb, LB 6419 and LB 6420. The measurements of their responses are reported and compared with the calculated values.

    In Japan, archeomagnetic measurements are vigorously developed for years, though it is not well known to paleomagnetism community in english. One of the works is massive archeomagnetic study of Suemura kiln group carried out in Osaka University in 1960's to early 70's. More than 500 kilns were excavated in Sakai city and vicinities, Osaka Prefecture, Japan. The kiln group is called as Suemura Kilns, and are for Sueki earthenware of 5c to 10c CE. About 300 kilns were sampled and most of the samples were measured at the time, and the results are reported in e.g. Hirooka (1971) and Shibuya (1980). However, the results have significant scatter in direction, which may be due to the limitation of old astatic magnetometer measurements and handwriting graphic determination of magnetic direction, and/or the lack of demagnetization. We recently inherited many of those samples and remeasured them with spinner magnetometer applying alternation field demagnetization (afd). The magnetizations are generally very stable, as usual as other archeomagnetic samples, and afd does not change the magnetic direction mostly. However, significant number of sites show large scatter in magnetic directions, which might be due to the wrong identification of kiln floor or disturbance at the time of collapsing or excavation. Taking kilns of α95<4o, we recovered 131 paleomagnetic directions. Although third of them are dated by pottery shape chronology, the range of each pottery style is not precisely known and the relation of the baked floor and the potteries excavated around kilns are not always clear. The carbon dating of those kilns are very scares. Thus we first try to draw secular variation curve in declination-inclination plot. With the rough ages of those kilns, it is pretty easy to draw the SVC. It is also numerically determined taking the distance of each direction from nearest point in SVC and the velocity change of the SVC as penalty function, within a couple of degrees in the error

    One of the worst earthquakes hit the Hanshin area between Kobe and Osaka, in the early morning at 5:46 AM on January 17th 1995. The destructive force with MG 7.2 severely damaged buildings, houses, roads and railways, leaving 6500 dead, and 34,900 injured. Hyogo College of Medicine located in this area was also severely damaged, thus there was a major challenge to provide post-quake medical support. A post-quake investigation in this area was done by 50 affiliated hospitals. More than 15,000 victim-patients were treated at these hospitals during the first 3 days after the quake. Major injuries were spinal fractures, and other trunk fractures, including rib or pelvis fractures, but fractures of long bones were uncommon, because the quake hit this area in the early morning when most people were asleep. In this study, the mechanisms of these major injuries were analysed by direct interview soon after the quake, with 230 victim-patients who had 140 spinal fractures, and 100 with rib or pelvis fractures. Most of those who had a spinal fracture had either sat up or stood up on their 'Futon' mattresses without bed frames and were struck on their backs by falling furniture or ceilings. On the other hand, patients who had fractures of the ribs or the pelvis had been lying in the supine or lateral position and were hit on their chest or pelvis. This characteristic lifestyle pattern of the Japanese people to lie down on the floor directly beside furniture, resulted in these injuries. From these results, we will emphasize the following precautions:- If an earthquake occurs during sleeping hours at home, do not stand up or sit up. The best position is to crouch on the 'Futon' mattress.

    STUDY OBJECTIVE: To examine the relationships between the use of preventive health services--such as health checks, basic health examination/cancer screening, and daily preventive health practices--and survival of elderly people living in the community. DESIGN AND SETTING: A cohort of elderly people aged 65 years and over living in Settsu City, Osaka was followed for 38 months. Data on the history of health management, disability scores, and psychosocial conditions were collected in October 1992 by interview during home visits. SUBJECTS: Of the 1491 people randomly selected from the computerised sex-age register at enrollment, 1473 were contacted and responses were obtained from 1405 (95.4%). They constituted the study cohort. Follow up was completed for 1325 (94.3%) (154 decreased and 1171 alive). MEASUREMENTS AND MAIN RESULTS: From the analysis using the Kaplan-Meier method and the log-rank test, female sex, younger age group (65-74 years), use of health checks, use of basic health examination and/or cancer screening, use of daily preventive health practices, less disability, taking part in social activity, and finding life worth living were univariately statistically significantly related to survival. The estimated survival rates were highest in those with regular health checks or daily preventive health practices before 59 years of age or both basic health examination and cancer screening. From the Cox proportional hazards model, use of health checks and use of daily preventive health practices remained as statistically significant factors associated with survival, controlling for other factors such as sex, age group, medical treatment, disability scores, and psycho-social conditions, and these hazard ratios (not used v starting at 59 years) were 0.41 (95% CI, 0.25, 0.66) and 0.52 (95% CI, 0.30, 0.88), respectively. CONCLUSIONS: Health management efforts such as health checks and daily preventive health practices may increase survival in the elderly. PMID

    Detailed studies on the commercial development of biotechnology in five countries in the Asian Region (viz. Japan, Korea, Taiwan, Thailand, India) indicate a very significant role played by government in strategic planning and R & D financing. Strong growth is projected in some traditional biotechnology products e.g. amino acids such as monosodium glutamate and L-lysine, animal and human vaccines, and in environmental applications of biotechnology. The cash flow from these products will underpin future development and marketing of diagnostics, anticancer and antiviral drugs, particularly in Japan and Korea.

    This paper describes the results of neutron spectrometry and dosimetry measurements using an extended range Bonner Sphere Spectrometer (ERBSS) with 3He proportional counter performed in quasi-mono-energetic neutron fields at the ring cyclotron facility of the Research Center for Nuclear Physics (RCNP), Osaka University, Japan. Using 100 MeV and 296 MeV proton beams, neutron fields with nominal peak energies of 96 MeV and 293 MeV were generated via 7Li(p,n)7Be reactions. Neutrons produced at 0° and 25° emission angles were extracted into the 100 m long time-of-flight (TOF) tunnel, and the energy spectra were measured at a distance of 35 m from the target. To deduce the corresponding neutron spectra from thermal to the nominal maximum energy, the ERBSS data were unfolded using the MSANDB unfolding code. At high energies, the neutron spectra were also measured by means of the TOF method using NE213 organic liquid scintillators. The results are discussed in terms of ambient dose equivalent, H*(10), and compared with the readings of other instruments operated during the experiment.

    A publicly available atmospheric transport model, the Weather Research and Forecasting Chemistry Model ( http://ruc.noaa.gov/wrf/WG11/ ), was used to simulate atmospheric perfluorooctanoic acid (PFOA) and perfluorooctanoate (PFO) emitted from a point source in the Osaka urban area (also known as Keihanshin), Japan. The time period of the simulation was from 1983 to 2008. The modeled air concentrations were highly correlated (r = 0.91) with the observed air concentrations. Intake levels by inhalation of simulated air concentrations and through the gastrointestinal tract as estimated by the food duplicate method were input to a pharmacokinetic model of the human body to simulate serum concentrations of PFOA and PFO (PFO(A)). For validation of the atmospheric model, simulated values were compared with those observed in serum samples. The simulated values generally agreed with those observed in serum samples from residents of the Keihanshin area (r = 0.93). It was confirmed that the atmospheric model was generally capable of projecting features of atmospheric PFO(A) as well as serum concentrations of PFO(A) in this case. The results indicated a dominant contribution of the atmospheric component to serum PFO(A) in humans near the point source in the Keihanshin area. In 2008, that contribution was about 70%.

    The source and routes of diarrheagenic Escherichia coli (DEC) remain poorly understood. To investigate the involvement of domestic animals in the dissemination of DEC, the prevalence of DEC in foods and fecal specimens from cattle, pigs, chickens, healthy carriers, and patients in Osaka and Hyogo, Japan was investigated using a multiplex real-time Polymerase Chain Reaction assay. The most abundant virulence genes were astA and eae, which had a prevalence 46.8% and 27.4%, respectively. Additionally, stx1 (26.6%) and stx2 (45.9%) were prevalent in cattle feces, while est (8.5%) and elt (7.6%) were prevalent in pig feces. afaB was the second-most prevalent gene in patients and healthy carriers, and it had detection rates of 5.1% and 8.1%, respectively. In contrast, afaB was not detected in animal feces or foods, except for three porcine fecal samples. The aggR gene was more prevalent in humans than in foods or animal feces. Both Shiga toxin-producing E. coli and atypical enteropathogenic E. coli carried by cattle may be sources for diarrheal diseases in humans. Pigs may be a source for human enterotoxigenic E. coli infections, whereas humans are expected to be the reservoir for diffusely adhering E. coli, enteroaggregative E. coli, and enteroinvasive E. coli.

    Public concern regarding the transport of air pollutants from mainland East Asia to the leeward area by the prevailing westerlies in spring and winter monsoon has been growing in recent years. We collected total suspended particle (TSP) in Beijing, a metropolis of China located windward of Japan, in spring (late February 2011-May 2011) and in winter (November 2012-early February 2013), then analyzed metals, ions, and organic compounds and mutagenicity, and compared the pollution levels with samples collected at two Japanese metropolises (Osaka and Nagoya) during the same periods. The medians of concentration of TSP and other factors in Beijing were much larger than those in the Japanese metropolises. Especially, the concentrations of polycyclic aromatic hydrocarbons (PAHs) were remarkably high in Beijing in winter, and the median of total PAHs concentration in Beijing was 62-63 times larger than that in the Japanese sites. The mutagenicity of TSP from Beijing toward Salmonella typhimurium YG1024, with and without a mammalian metabolic system (S9 mix), was 13-25 times higher than that from the Japanese sites in winter. These results suggest that air pollution levels in Beijing are very high compared with those at the two Japanese metropolises we evaluated. The diagnostic ratios of PAHs and nitrated polycyclic aromatic hydrocarbons (NPAHs) suggest that the major sources of PAHs and NPAHs in Beijing are different from those at the two Japanese sites in winter, and that the major source in Beijing is coal/biomass combustion.

    Observed correlation between galactic cosmic ray (CR) flux and cloud cover suggests that variations in geomagnetic field intensity could change climate through modulation of CR flux. Kitaba et al. (2013) reported a pollen-based climate cooling that coincided with a large decrease in field intensity during the Matuyama-Brunhes and Lower Jaramillo geomagnetic polarity reversals using a sediment core from Osaka Bay, Japan. The cooling event is not attributed to orbital forcing, but to the geomagnetic field intensity variation through modulation of CR flux. If the geomagnetic field intensity disturbs global heat balance, it may further affect monsoon and/or precipitation. Our pollen-based climate data show that during the cooling the difference in mean temperature between the warmest and coldest months (indicator of land-ocean temperature gradient) increased, and the summer precipitation (indicator of summer monsoon intensity) decreased. Assuming a simple model that the monsoon is driven by the land-ocean temperature gradient, the cooling effect would be larger over the land than the sea.

    We aimed to investigate prehospital factors associated with difficulty in hospital acceptance among elderly emergency patients. We reviewed ambulance records in Osaka City from January 2013 through December 2014, and enrolled all elderly emergency patients aged ≥65 years who were transported by on-scene emergency medical service personnel to a hospital that the personnel had selected. The definition of difficulty in hospital acceptance was to the requirement for ≥4 phone calls to hospitals by emergency medical service personnel before receiving a decision from the destination hospitals. Prehospital factors associated with difficulty in hospital acceptance were examined through logistic regression analysis. During the study period, 72 105 elderly patients were included, and 13 332 patients (18.5%) experienced difficulty in hospital acceptance. In the simple linear regression model, hospital selection time increased significantly with an increasing number of phone calls (R(2)  = 0.774). In the multivariable analysis, older age (P for trend <0.001), calls from a healthcare facility (adjusted odds ratio [AOR] 1.23, 95% confidence interval [CI] 1.15-1.32), night-time (AOR 2.17, 95% CI 2.08-2.26) and weekend/holidays (AOR 1.43, 95% CI 1.38-1.49) were significantly associated with difficulty in hospital acceptance. A positive association was observed between gastrointestinal emergency-related symptoms and difficulty in hospital acceptance among elderly patients with symptoms of internal disease (AOR 1.71, 95% CI 1.53-1.91). In Japan, which has a rapidly aging population, a comprehensive strategy for elderly emergency patients, especially for advanced age groups or nursing home residents, is required.

    The tuberculosis (TB) notification in Osaka City has been persistently high compared with other urban areas in Japan. Although the TB notification in Greater London has kept much lower level compared with that in Osaka City, it has been also persistently high compared with other urban areas in the UK. Nonetheless, the contexts of the two cities relating TB control programme as well as the epidemiological situation greatly vary; there must be some lessons to be learnt from each other to improve each TB control programme to tackle against TB more effectively. Comparing the epidemiological situation of TB in both cities, it is obvious that Osaka City suffers TB more than Greater London in terms of the TB notification rate. Concerning the context of the TB control programme, Osaka City has centralised approach with strong local government commitment; Greater London, on the other hand, has an approach that is greatly fragmented but coordinated through voluntary TB Networks. This paper aims to draw some constructive and practical lessons from Greater London TB control management for further improvement of Osaka City TB control management through literature review and interview to health professionals. TB epidemiology in Greater London shows distinct features in the extent of TB in new entrants and TB co-infected with HIV in comparison with those in Osaka City. TB epidemiology in Osaka City is to a great extent specifically related to homeless people whereas in Greater London, this relationship occurs to a lesser extent. Both areas have relatively high TB-notification rates compared with national figures, and they have "TB hot spots" where remarkably high TB-notification rates exist. TB control in Greater London is characterised with decentralised and devolved services to local government health authorities supplemented with co-ordinating bodies across sectors as well as across Greater London.

    We established a multi-center, prospective cohort that could provide appropriate therapeutic strategies such as criteria for the introduction and the effectiveness of in-hospital advanced treatments, including percutaneous coronary intervention (PCI), target temperature management, and extracorporeal cardiopulmonary resuscitation (ECPR) for out-of-hospital cardiac arrest (OHCA) patients. In Osaka Prefecture, Japan, we registered all consecutive patients who were suffering from an OHCA for whom resuscitation was attempted and who were then transported to institutions participating in this registry since July 1, 2012. A total of 11 critical care medical centers and one hospital with an emergency care department participated in this registry. The primary outcome was neurological status after OHCA, defined as cerebral performance category (CPC) scale. A total of 688 OHCA patients were documented between July 2012 and December 2012. Of them, 657 were eligible for our analysis. Patients' average age was 66.2 years old, and male patients accounted for 66.2 %. The proportion of OHCAs having a cardiac origin was 50.4 %. The proportion as first documented rhythm of ventricular fibrillation/pulseless ventricular tachycardia was 11.6 %, pulseless electrical activity 23.4 %, and asystole 54.5 %. After hospital arrival, 10.5 % received defibrillation, 90.8 % tracheal intubation, 3.0 % ECPR, 3.5 % PCI, and 83.1 % adrenaline administration. The proportions of 90-day survival and CPC 1/2 at 90 days after OHCAs were 5.9 and 3.0 %, respectively. The Comprehensive Registry of In-hospital Intensive Care for OHCA Survival (CRITICAL) study will enroll over 2000 OHCA patients every year. It is still ongoing without a set termination date in order to provide valuable information regarding appropriate therapeutic strategies for OHCA patients (UMIN000007528).

    The 5th World Congress on Biomimetics, Artificial Muscles and Nano-Bio and the 4th International Conference on Artificial Muscles were held in Osaka, Japan, 23-27 November 2009. This special section of Smart Materials and Structures is devoted to a selected number of research papers presented at this international conference and congress. Of the 76 or so papers presented at the conference, only 10 papers were finally selected, reviewed and accepted for this special section, following the regular reviewing procedures of the journal. This special section is focused on polymeric artificial muscles, electroactive polymers, multifunctional nanocomposites and their applications. In particular, an electromechanical model for self-sensing ionic polymer-metal composite actuating devices with patterned surface electrodes is presented which discusses the concept of creating self-sensing ionic polymer-metal composite (IPMC) actuating devices with patterned surface electrodes where actuator and sensor elements are separated by a grounded shielding electrode. Eventually, an electromechanical model of the device is also proposed and validated. Following that, there is broad coverage of polytetrahydrofurane-polyethylene oxide-PEDOT conducting interpenetrating polymer networks (IPNs) for high speed actuators. The conducting polymer (poly(3,4-ethylenedioxythiophene)) is incorporated within the IPNs, which are synthesized from polyethylene oxide (PEO)/polytetrahydrofurane (PTHF) networks. PEO/PTHF IPNs are prepared using poly(ethylene glycol) methacrylate and dimethacrylate and hydroxythelechelic PTHF as starting materials. The conducting IPN actuators are prepared by oxidative polymerization of 3,4-ethylenedioxithiophene (EDOT) using FeCl3 as an oxidizing agent within the PEO/PTHF IPN host matrix. Subsequently, giant and reversible magnetorheology of carrageenan/iron oxide magnetic gels are discussed and the effect of magnetic fields on the viscoelastic properties

    In 2009, the first high-level ceftriaxone-resistant Neisseria gonorrhoeae strain (H041) was isolated in Kyoto, Japan. The present study describes an intensified surveillance (antimicrobial resistance and molecular typing) of Neisseria gonorrhoeae isolates in Kyoto and its neighboring prefecture Osaka, Japan, in 2010 to 2012, which was initiated after the identification of H041. From April 2010 to March 2012, 193 N. gonorrhoeae isolates were collected and the MICs (μg/ml) to six antimicrobials, including ceftriaxone, were determined. All isolates showed susceptibility to ceftriaxone and cefixime (MIC values, <0.5 μg/ml), and spectinomycin. The rates of resistance (intermediate susceptibility) to azithromycin, penicillin G, and ciprofloxacin were 3.6% (19.7%), 24.4% (71.0%), and 78.2% (0.5%), respectively. Multilocus sequence typing (MLST) showed that 40.9%, 19.2%, and 17.1% of isolates belonged to ST1901, ST7359, and ST7363, respectively. Furthermore, N. gonorrhoeae multiantigen sequence typing (NG-MAST) revealed that 12 (63%) of the 19 isolates with decreased susceptibility to ceftriaxone (MIC > 0.064 μg/ml) were of ST1407. NG-MAST ST1407 was also the most prevalent ST (16.1%; 31 of 193 isolates). In those NG-MAST ST1407 strains, several mosaic type penA alleles were found, including SF-A type (penicillin binding protein 2 allele XXXIV) and its derivatives. These were confirmed using transformation of the penA mosaic alleles as critical determinants for enhanced cefixime and ceftriaxone MICs. The intensified surveillance in Kyoto and Osaka, Japan, did not identify any dissemination of the high-level ceftriaxone-resistant N. gonorrhoeae strain H041, suggesting that H041 might have caused only a sporadic case and has not spread further.

    Vaginal cancer is such a rare tumor that epidemiological and clinical information for it is based mainly on studies of small numbers of cases. The aim of the present study was to perform a descriptive epidemiological analysis of vaginal cancer using a significantly larger population-based dataset from the Japanese Osaka Cancer Registry.The age-standardized incidence of vaginal cancer per 1,000,000 persons, from 1976 to 2010, was calculated and examined for trends. Relative-survival analysis was applied to estimate a more up-to-date 10-year period calculation, using data from recently followed-up patients. The conditional 5-year survival of patients who survived for 0 to 5 years after diagnosis was calculated.A total of 481 cases of vaginal cancer were registered in Osaka during the 35-year period from 1976 to 2010. The age-adjusted incidence rate has significantly and consistently decreased over this time [annual percent change (APC) = -1.29, 95% confidence interval (95% CI): -0.3 ∼ -2.2]; however, due to significant population aging, the raw incidence of vaginal cancer appeared to have been increasing. The 10-year relative survival of patients with surgery-based treatments was comparable to that of radiation-based treatments, implying that surgery and radiotherapy provide similar therapeutic benefits (P = .98). The 10-year relative survival was not significantly different during the period of 1976 to 2000 compared with the period of 2001 to 2008, although there has been, in the latter period, a tendency for improvement of long-term survival, especially for survival longer than 5 years. The longer the time after diagnosis, the higher the conditional 5-year relative-survival at 0 to 4 years after diagnosis.The age-adjusted incidence of vaginal cancer has decreased since 1976. Regrettably, the 10-year survival rate did not similarly improve, and it remained stable during the period from 2001 to 2008, compared with the period from 1976 to 2000, indicating

    Field surveys and laboratory experiments were conducted to examine the effect of desiccation and salinity on the outbreak of a green tide of Ulva pertusa at Osaka Nanko bird sanctuary. Reduction of biomass of Ulva spp. was observed at stations where the exposure rate to air was from 30 to 40%. In addition, the exposure rate of 30-40% to air showed no negative impacts on the biomass of benthic microalgae, infauna and non-motile epibenthos. Laboratory experiments revealed that photosynthetic activity of U. pertusa decreased when exposed to air for 4-7 h at 25-35 °C. Salinity decreases from 30 to 25 or 20 accompanied with exposure to air drastically reduced the rate of photosynthesis of this species. These results suggest the possibility of controlling a green tide of U. pertusa without serious physico-ecological damage to benthic microalgae, infauna and non-motile epibenthos by a combination of exposure to air with low salinity.

    This study was conducted to clarify the spatial distributions of perfluorooctanoic acid (PFOA) and perfluorohexanoic acid (PFHxA) in well, surface and tap water around a fluoropolymer plant in Osaka between 2003 and 2016 and to predict the fate of those chemicals in these aquatic environments. We analyzed 44 well, six surface and six tap water samples collected within a 5 km radius of the plant. The PFOA concentrations in well water ranged from 45.2 to 7440 ng/L (median = 240 ng/L), while PFHxA concentrations ranged from 9.68 to 970 (median = 45.4 ng/L) in 2015-2016. The concentration of other perfluoroalkyl carboxylic acids were lower than PFOA and PFHxA in well water. Fixed-point observation showed that the levels of PFOA decreased greatly over the last few decades, whereas those of PFHxA increased in both well and surface water. Further monitoring and investigation are suggested to understand PFOA and PFHxA contamination and fate in the environment, as well as their potential for human exposure in this region.

    In 2004, the Japanese government halted the 6-month mass screening program for neuroblastoma. We investigated whether its cessation had led to an increase not only in mortality due to this disease but also in the incidence of advanced-stage disease among older children. Study subjects were neuroblastoma patients retrieved from the population-based Osaka Cancer Registry. Trends of incidence and mortality from neuroblastoma were analyzed by calendar year and birth cohort. Prognostic factors, including stage and v-myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog (MYCN) oncogene status, were compared before and after the cessation of mass screening. Age-standardized incidence rates in 2005-2009 (the cessation period of mass screening; 11.1 per million) were similar to those in 1975-1979 (the pre-screening period; 8.6 per million). Age-standardized mortality rates tended to decrease from 1975-1979 (4.0 per million) to 2005-2009 (2.7 per million) in parallel with the improvement in survival. Analysis by birth cohort indicated that the mortality rates in 2004-2005 (after cessation) for children 0-4 years of age were lower than those in 1975-1979 (O:E ratio 0.25; 95% confidence interval, 0.03-0.90). For children 1-9 years of age, there was a not significant difference in the distribution of stage, MYCN oncogene status, and DNA ploidy between 1991-2003 (the mass screening period) and 2004-2008 (after cessation). The cessation of mass screening for neuroblastoma does not appear to have increased mortality due to this disease or incidence of advanced-stage disease among older children.

    We examined the relationships between preventive health services provided under the Law for Health and Medical Services for the Elderly and the use of inpatient and outpatient care by insured residents aged 40 or older covered by the National Health Insurance in 44 municipalities in Osaka Prefecture. Factor analyses showed that hospital admission rate and inpatient days per 100 insured persons, bed days per insured person, inpatient days per case, mean bed days, the proportion of long-stay (180 days or more), and the rate of long-stay per 1,000 insured persons accounted for the first factors of inpatient care with factor loadings of more than 0.82. Outpatient utilization rate and outpatient days per 100 insured persons comprised the first factors of outpatient care with factor loadings of more than 0.80. Patient cost per case and the proportion of high patient cost (600,000 Yen or more for inpatient care and 60,000 Yen or more for outpatient care) made up the second factors of either type of patient care with factor loadings of more than 0.87. The frequency of use of health check-ups and the numbers of instruction classes and participants in health education and health counseling per 100 residents showed negative correlations with indices of inpatient and outpatient care, except for patient cost per day. The scores for the first and second factors of inpatient care and for the first factor of outpatient care correlated negatively with all indices of the use of preventive health services. More active provision of preventive health services may therefore contribute to reducing the subsequent use of inpatient and outpatient care among residents aged 40 or older.

    Background Recently, the number of ambulance dispatches has been increasing in Japan, and it is therefore difficult for hospitals to accept emergency patients smoothly and appropriately because of the limited hospital capacity. To facilitate the process of requesting patient transport and hospital acceptance, an emergency information system using information technology (IT) has been built and introduced in various communities. However, its effectiveness has not been thoroughly revealed. We introduced a smartphone app system in 2013 that enables emergency medical service (EMS) personnel to share information among themselves regarding on-scene ambulances and the hospital situation. Objective The aim of this study was to assess the effects of introducing this smartphone app on the EMS system in Osaka City, Japan. Methods This retrospective study analyzed the population-based ambulance records of Osaka Municipal Fire Department. The study period was 6 years, from January 1, 2010 to December 31, 2015. We enrolled emergency patients for whom on-scene EMS personnel conducted hospital selection. The main endpoint was the difficulty experienced in gaining hospital acceptance at the scene. The definition of difficulty was making ≥5 phone calls by EMS personnel at the scene to hospitals until a decision to transport was determined. The smartphone app was introduced in January 2013, and we compared the patients treated from 2010 to 2012 (control group) with those treated from 2013 to 2015 (smartphone app group) using an interrupted time-series analysis to assess the effects of introducing this smartphone app. Results A total of 600,526 emergency patients for whom EMS personnel selected hospitals were eligible for our analysis. There were 300,131 emergency patients in the control group (50.00%, 300,313/600,526) from 2010 to 2012 and 300,395 emergency patients in the smartphone app group (50.00%, 300,395/600,526) from 2013 to 2015.

    Studies of the dietary intake of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like coplanar polychlorinated biphenyls (dioxin-like PCBs), collectively referred as dioxins, were conducted using the total diet study (TDS) method with food purchased in Osaka City, Japan during 2000-2002. The daily intake of dioxin-TEQ (toxic equivalent) from food per adult person was estimated respectively as 104.24 pg TEQ/person/day in 2000, 72.73 pg TEQ/person/day in 2001, and 87.28 pg TEQ/person/day in 2002, corresponding to 2.08, 1.45, and 1.74 pg TEQ/kg body weight (bw)/day for an adult weighing 50 kg. The highest contribution ratio to the total intake of dioxin-TEQ was from fish and shellfish (group 10) in each year, accounting for 77-92%. The next highest contributor was meat and eggs (groups 11-A and 11-B). An annual decrease of the intake of dioxin-TEQ was not observed clearly. Otherwise, the dietary intake of non-2,3,7,8-substituted PCDDs/PCDFs were estimated together. The intake of 1,3,6,8-TeCDD came mostly from intake of fish and shellfish (group 10), green vegetable (group 7), and the other vegetables, including mushrooms and seaweed (group 8). In addition, the intake of 1,3,6,8-TeCDF, which reportedly antagonizes 2,3,7,8-TeCDD-mediated aryl hydrocarbon hydroxylase (AHH) and ethoxyresorufin O-deethylase (EROD) induction activities, was an insufficient amount to suppress 2,3,7,8-TeCDD-mediated activities. Furthermore, we discussed different TEQ compositions of PCDDs/PCDFs to dioxin-like PCBs from food intake and in human samples and inferred that the difference was caused by low bioaccumulation properties of 3,3',4,4',5-PeCB (PCB 126). © Springer Science+Business Media, LLC 2010

    Background Several studies have reported that individualized residential place-based discrimination (PBD) affects residents’ health. However, studies exploring the association between institutionalized PBD and health are scarce, especially in Asian countries including Japan. Methods A cross-sectional study was conducted with random two-stage sampling of 6191 adults aged 25–64 years in 100 census tracts across Osaka city in 2011. Of 3244 respondents (response rate 52.4%), 2963 were analyzed using multilevel logistic regression to examine the association of both individualized and institutionalized PBD with self-rated health (SRH) after adjustment for individual-level factors such as socioeconomic status (SES). An area-level PBD indicator was created by aggregating individual-level PBD responses in each tract, representing a proxy for institutionalized PBD, i.e., the concept that living in a stigmatized neighborhood affects neighborhood health. 100 tracts were divided into quartiles in order. The health impact of area-level PBD was compared with that of area-level SES indicators (quartile) such as deprivation. Results After adjustment for individual-level PBD, the highest and third area-level PBD quartiles showed odds ratio (OR) 1.57 (95% credible interval: 1.13-2.18) and 1.38 (0.99-1.92), respectively, for poor SRH compared with the lowest area-level PBD quartile. In a further SES-adjusted model, ORs of area-level PBD (highest and third quartile) were attenuated to 1.32 and 1.31, respectively, but remained marginally significant, although those of the highest area-level not-home-owner (census-based indicator) and deprivation index quartiles were attenuated to 1.26 and 1.21, respectively, and not significant. Individual-level PBD showed significant OR 1.89 (1.33-2.81) for poor SRH in an age, sex, PBD and SES-adjusted model. Conclusion Institutionalized PBD may be a more important environmental determinant of SRH than other area-level SES indicators such as

    An outbreak of bile duct carcinoma has been reported among workers in a certain printing company in Osaka, Japan, where there was no descriptive epidemiological study. We conducted descriptive studies of bile duct carcinoma in Osaka. Based on the data from the Osaka Cancer Registry, the incidence and survival rate of intrahepatic and extrahepatic bile duct carcinomas, gallbladder carcinomas and hepatocellular carcinomas were analyzed. The study period was between 1975 and 2007, and total 108 407 incidents were retrieved from the Osaka Cancer Registry. Age- and sex-specific incidence rates and age-standardized incidence rates were calculated. Standardized incidence ratios were evaluated for each municipality in Osaka prefecture. Relative 5-year survival rates were also calculated for the cases diagnosed between 1993 and 2005. Age-standardized incidence rates of bile duct carcinomas increased distinctly from the middle of the 1970s to the early 1980s in males and the 1990s in females. However, no distinct increase in the incidence rates was observed in 2000. Standardized incidence ratios of those did not exceed the unity significantly in males between 1992 and 2007. In females, standardized incidence ratios exceeded the unity significantly in a few regions without any relation to the location of the printing company where the outbreak was reported. The relative 5-year survival rate is generally poor; however, patients who were diagnosed with localized disease at the age of 25-49 years showed a better survival. Neither change in trend nor regional accumulation of bile duct carcinoma was confirmed in Osaka, corresponding to the outbreak reported in the printing company.

    The International Joint AIRAPT-22 & HPCJ-50 Conference was held in Odaiba, Tokyo, on 26-31 July 2009. About 480 scientists from 24 countries attended the conference and 464 papers, including 3 plenary lectures, 39 invited talks, and 156 oral presentations, were presented. It is my great pleasure to present this proceedings volume, which is based on the high quality scientific works presented at the conference. The International AIRAPT conference has been held every two years in various countries around the world since 1965, while High Pressure Conference of Japan (HPCJ) has been held annually since 1959 in various Japanese cities. Pressure is a fundamental parameter to control the property of matter. As a result, both AIRAPT and HPCJ have become highly multidisciplinary, and cover Physics, Chemistry, Materials Science, Earth and Planetary Sciences, Biosciences, Food Science, and Technology. Although each discipline has a unique target, they all have high-pressure research in common. This proceedings volume includes about 200 papers of state-of-the-art studies from numerous fields. I hope this proceedings volume provides excellent pieces of information in various fields to further advance high-pressure research.

  10. Waveform simulation of predominant periods in Osaka basin

    Predominant period of strong ground motions is an important parameter in earthquake engineering practice. Resonance at predominant period may result in collapse of building. Usually, predominant periods are associated with the soil resonances. However, considering that strong ground motions are composed from source, path and site effects, predominant periods are affected by source and propagation path too. From another side, 3D basin interferences may amplify quite different periods, depending on site location relatively to the basin edges and independently on the soil depth. Moreover, constructive or destructive interference of waves from different asperities of a large source may enhance or diminish amplitudes at a particular predominant period respectively. In this study, to demonstrate variations of predominant periods due to complicated effects above, we simulated wavefield snapshots and waveforms at a few representative sites of Osaka basin, Japan. Seismic source is located in Nankai trough, hosting anticipated M9 earthquake. 3D velocity structure is combined from JIVSM velocity structure (Koketsu et al., 2012) and Osaka basin structure of Iwaki and Iwata, 2011. 3D-FDM method is used to simulate waveforms. Simulation results confirm some previous results that due to elongated elliptical shape of Osaka basin, interference effects are strong and peak amplitudes has characteristic stripped pattern elongated in parallel to the long axis of basin. We demonstrate that predominant periods have similar pattern and value of predominant period may strongly depend on the location of site and azimuthal orientation of waveform component.

    Traditionally, Japan has been regarded as a country with low crime. Comparative research has given insights into the extent of similarities and differences in crime between America and Japan. The importance of these studies is the examination of whether Western-established criminological knowledge is applicable to non- Western societies like Japan. Unfortunately, comparative self-report studies involving Japan and investigating youth offending are scarce. The current study investigates risk factors and self-reports of violence from Osaka and Seattle male youths. The findings reveal that Japanese male youths self-report a higher prevalence of violence than Seattle male youths. Risk factors for violence, issues of comparability, and prevalence versus strength of relationships of risk factors are examined. It is concluded that the higher prevalence of violence in Osaka is primarily a function of the higher prevalence of troubled peers and risk taking. The findings call for replication of this type of comparative research. PMID:24013769

    Japan consists of 3900 islands and lies off the east coast of Asia. Even though Japan is one of the most densely populated nations in the world, its growth rate has stabilized at .5%. 94% of all children go to senior high school and almost 90% finish. Responsibility for the sick, aged, and infirmed is changing from the family and private sector to government. Japan was founded in 600 BC and its 1st capital was in Nara (710-1867). The Portuguese, the 1st Westerners to make contact with Japan in 1542, opened trade which lasted until the mid 17th century. US Navy Commodore Matthew Perry forced Japan to reopen in 1854. Following wars with China and Russia in the late 1800s and early 1900s respectively, Japan took part in World Wars I and II. In between these wars Japan invaded Manchuria and China. The US dropped an atomic bomb on Hiroshima and Nagasaki and the Japanese surrendered in September, 1945 ending World War II (WWII). Following, WWII, the Allied Powers guided Japan's establishment as a nonthreatening nation and a democratic parliamentary government (a constitutional monarchy) with a limited defense force. Japan remains one of the most politically stable of all postwar democracies. The Liberal Democratic Party's Noboru Takeshita became prime minister in 1987. Japan has limited natural resources and only 19% of the land is arable. Japanese ingenuity and skill combine to produce one of the highest per hectare crop yields in the world. Japan is a major economic power, and its and the US economies are becoming more interdependent. Its exports, making up only 13% of the gross national product, mainly go to Canada and the US. Many in the US are concerned, however, with the trade deficit with Japan and are seeking ways to make trade more equitable. Japan wishes to maintain good relations with its Asian neighbors and other nations. The US and Japan enjoy a strong, productive relationship.

  18. Japan - UK Conference: Trends in Physics and Chemistry Education in Secondary Schools

    1998-11-01

    This conference, held in Tokyo between 3-5 April 1998, was the most recent product of a now longstanding involvement between British and Japanese physics teachers which has grown out of a personal friendship between Brenda Jennison (Cambridge University and Vice Chair of the Education Group) and Tae Ryu (Sophia University). For a number of years British teachers have hosted Japanese counterparts at the annual ASE meetings and in visits to schools following the conference. For this conference a team of four physicists, Brenda Jennison, lan Lawrence (King's School Worcester), Philip Britton (Leeds Grammar School) and Phil Scott (University of Leeds) travelled to Japan to contribute to a conference and visit schools and University Departments. Feelings on reading a conference report can too often resemble the experience of being shown a friend's holiday snaps. They are clearly very interesting but equally clearly your friend is enjoying it more than you are, because the snaps are rekindling memories and thoughts. This set of reflections is an attempt to report on just four of those memories and thoughts rather than describe the pictures. Why organize an international conference? The conference was an event that almost took more months of tireless organization than it lasted in hours. It was conceived and brought to fruition amongst a welter of e-mail communications between Brenda Jennison, Tae Ryu and Maurice Jenkins of the British Council, who sponsored the event. Given this immense organizational task, just why did we bother? What can be gained by holding such an international event? The significant benefit of discussing issues between two cultures is clarifying which are the issues that are intrinsically due to the nature of physics teaching rather than the extrinsic effects of educational systems and customs. Unsurprisingly pupil motivation, pupil numbers, relevance, `up-to-date-ness' and the role of mathematics emerged as concerns in both cultures. Also there are

  19. Long-period Ground Motion Simulation in the Osaka Basin during the 2011 Great Tohoku Earthquake

    Large amplitude long-period ground motions (1-10s) with long duration were observed in the Osaka sedimentary basin during the 2011 Tohoku earthquake (Mw9.0) and its aftershock (Ibaraki-Oki, Mw7.7), which is about 600 km away from the source regions. Sato et al. (2013) analyzed strong ground motion records from the source region to the Osaka basin and showed the following characteristics. (1) In the period range of 1 to 10s, the amplitude of horizontal components of the ground motion at the site-specific period is amplified in the Osaka basin sites. The predominant period is about 7s in the bay area where the largest pSv were observed. (2) The velocity Fourier amplitude spectra with their predominant period of around 7s are observed at the bedrock sites surrounding the Osaka basin. Those characteristics were observed during both of the mainshock and the largest aftershock. Therefore, large long-period ground motions in the Osaka basin are generated by the combination of propagation-path and basin effects. They simulated ground motions due to the largest aftershock as a simple point source model using three-dimensional FDM (GMS; Aoi and Fujiwara, 1999). They used a three-dimensional velocity structure based on the Japan Integrated Velocity Structure Model (JIVSM, Koketsu et al., 2012), with the minimum effective period of the computation of 3s. Their simulation result reproduced the observation characteristics well and it validates the applicability of the JIVSM for the long period ground motion simulation. In this study, we try to simulate long-period ground motions during the mainshock. The source model we used for the simulation is based on the SMGA model obtained by Asano and Iwata (2012). We succeed to simulate long-period ground motion propagation from Kanto area to the Osaka basin fairly well. The long-period ground motion simulations with the several Osaka basin velocity structure models are done for improving the model applicability. We used strong motion

    Japan is composed of 4 main islands and more than 3900 smaller islands and has 317.7 persons/square kilometer. This makes it one of the most densely populated nations in the world. Religion is an important force in the life of the Japanese and most consider themselves Buddhists. Schooling is free through junior high but 90% of Japanese students complete high school. In fact, Japan enjoys one of the highest literacy rates in the world. There are over 178 newspapers and 3500 magazines published in Japan and the number of new book titles issued each year is greater than that in the US. Since WW1, Japan expanded its influence in Asia and its holdings in the Pacific. However, as a direct result of WW2, Japan lost all of its overseas possessions and was able to retain only its own islands. Since 1952, Japan has been ruled by conservative governments which cooperate closely with the West. Great economic growth has come since the post-treaty period. Japan as a constitutional monarchy operates within the framework of a constitution which became effective in May 1947. Executive power is vested in a cabinet which includes the prime minister and the ministers of state. Japan is one of the most politically stable of the postwar democracies and the Liberal Democratic Party is representative of Japanese moderate conservatism. The economy of Japan is strong and growing. With few resources, there is only 19% of Japanese land suitable for cultivation. Its exports earn only about 19% of the country's gross national product. More than 59 million workers comprise Japan's labor force, 40% of whom are women. Japan and the US are strongly linked trading partners and after Canada, Japan is the largest trading partner of the US. Foreign policy since 1952 has fostered close cooperation with the West and Japan is vitally interested in good relations with its neighbors. Relations with the Soviet Union are not close although Japan is attempting to improve the situation. US policy is based on

    This article briefly highlights information provided by speakers at the World Conference of the International Union for Health Promotion and Education. The conference took place during August 1995, in Makuhari, Japan. One paper focused on health education in Japan, which would not be suitable for health promotion efforts in South Africa. Another paper focused on intersectoral efforts for health, policy, and networking. This paper addressed an issue important for all countries; the need for better communication among people working in health fields and improved outreach. A paper focusing on strengthening community action was presented. South Africa, as well as Japan, must work to involve communities in health service management. The author found that the paper on policy, practice, and research for health promotion and education was relevant to South Africa. Policymakers and practitioners tend to rely on precedence, intuition, personal experience, and political experience. Academic research funding does not support research that is relevant to policymakers and practitioners. The papers on healthy cities research were stimulating and had practical input. The proposed model involved a 3-phase and 14-step process of choosing a topic for an intervention, analyzing the intervention's political environment, and planning the political aspects of intervention. Another model of intersectoral action was spiral shaped and centered problem definition, direction setting, and structuring between networking and interorganizational relations. Four papers from Botswana focused on reproductive health. Other papers focused on teenage pregnancy.

    High concentrations of nitrogen dioxide are frequently observed in Osaka area in spring season. To clarify this, a series of three dimensional field observation was conducted in April 1993 covering Osaka and surrounding area. Vertical and horizontal distributions of ozone, NO, NO{sub x}, SO{sub 2}, CO, aerosol species, hydrocarbon species and meteorological parameter such as temperature, uv radiation, wind speed, wind direction are measured on the ground and aloft. Covering the observational period yellow sand transportation from the continent and stratospheric ozone intrusion were also observed under the meteorological condition of moving high pressure system. During the aircraft observation of 19 to 21 April 1993 high concentration of photochemical air pollution was observed aloft over Osaka area. Maximum ozone concentration was me than 150 ppb. Vertical distribution of ozone showed uniform profile up to 2500m in day time. At Mt. Ikoma (600 m) ozone concentration had been almost constant ranging 80-100 ppb throughout the observational period. To clarify this phenomena three dimensional photochemical air pollution simulation model was applied based on the real meteorological and emission conditions. Simulated result showed photochemical reaction play an important role to form the spring time high concentrations of nitrogen dioxide in Osaka.

    This is the first to elucidate the distribution and sources of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDFs), and dioxin-like polychlorinated biphenyls in the waters from Kanzaki River, which is one of the most heavily polluted rivers in Japan. The World Health Organization (WHO)-toxic equivalent quantities (TEQs) in waters from the mainstream exceeded the Japanese environmental standard (1.0 pg-TEQ/L). The PCDD/PCDFs were dominated by highly chlorinated DFs, which predominantly contributed to the WHO-TEQs, suggesting that the main causes would be the incineration-related wastes. To find the sources, the dioxin congener concentrations in water and sediment samples from its tributary small waterways were determined. Abnormally high WHO-TEQs were detected in a water (50 pg-TEQ/L) and a sediment sample (41,000 ng-TEQ/kg dry weight) near the industrial solid waste incinerators (ISWIs). The PCDD/PCDF characteristics agreed well with those of the incinerator-related wastes as seen in the mainstream. These facts indicate that the dioxin pollution in the mainstream could be largely related to the industrial wastes from the ISWIs. Here, a TEQ apportionment method was used to understand the contribution of the pyrogenic sources to the WHO-TEQs. The average contribution ratios of the pyrogenic sources to WHO-TEQs were more than 80% for river waters from the mainstream, indicating that the elevated WHO-TEQs in the mainstream had been largely caused by the ISWIs.

    This work intends to demonstrate the spatial and temporal variation of atmospheric particles in East Asia, especially around AERONET (Aerosol Robotics Network) -Osaka site during Dragon Asia period in the spring of 2012, named Dragon-Osaka. It is known that the air pollution in East Asia becomes to be severe due to both the increasing emissions of the anthropogenic aerosols associated with economic growth and the complicated behavior of natural aerosols. Thus the precise observations of atmospheric particles in East Asia are desired. Osaka is the second big city in Japan and a typical Asian urban area. The population of the region is around 20 millions including neighbor prefectures. Therefore, air quality in the region is slightly bad compared to remote area due to industries and auto mobiles. In recent years, Asian dusts and anthropogenic small particles transported from China and cover those cities throughout year. AERONET Osaka site was established in 2002 on the campus of Kinki University. Nowadays, LIDAR (Light Detection and Ranging), an SPM sampler (SPM-613D, Kimoto Electric, Japan) and others are available on the roof of a building. The site data are useful for algorithm development of aerosol retrieval over busy city. On the other hand, human activities in this region also emit the huge amount of pollutions, thus it is needed to investigate the local distribution of aerosols in this region. In order to investigate change of aerosol properties, PM-individual analysis is made with scanning electron microscope (SEM) coupled with energy dispersive X-ray analyzer (EDX). SEM/EDX is an effective instrument to observe the surface microstructure and analyze the chemical composition of such materials as metals, powders, biological specimens, etc. We used sampling data from the SPM sampler at AERONET Osaka site. During a period of DRAGON-Asia, high concentrations of air pollutant were observed on the morning of March 11 in Fukue Island in the East China Sea. On the

    Osaka Gas Co. has been developing a planar type SOFC (OG type SOFC) which has a suitable structure for stacking. Murata Mfg. Co. has begun to develop the OG type SOFC stack through joint program since 1993. Figure 1 shows OG type cell structure. Because each cell is sustained by cell holders acting air manifold, the load of upper cell is not put on the lower cells. Single cell is composed of 3-layered membrane and LaCrO{sub 3} separator. 5 single cells are mounted on the cell holder, connected with Ni felt electrically, and bonded by glassy material sealant. We call the 5-cell stack a unit. Stacking 13 units, we succeeded 870 W generation in 1993. But the power density was low, 0.11 Wcm{sup -2} because of crack in the electrolyte and gas leakage at some cells.

    With a broader aim of controlling pulmonary tuberculosis (TB) among foreigners, here, we have reported the findings of chest radiography screening for TB among international students at Japanese language schools in Osaka city. Between April 2011 and December 2013, 4,529 international students from 19 Japanese language schools in Osaka city underwent chest radiography for TB screening. The chest radiographs were studied in reference to the student's sex, age, nationality, and date of entry to Japan as well as any health conditions present at the time of screening. We further analyzed the bacterial information and pulmonary TB classification based on chest radiography findings of students who were identified to be positive for TB. Information on the implementation of health education was also gathered. The results revealed that 52.5% of the students who underwent chest radiography came from China, 20.3 % from South Korea, and 16.3% from Vietnam. Of the students, 52.9% were male and 47.1% were female. The median age of students was 23 years (range: 14-70 years). The median number of days from the first date of entry to Japan up until the radiography screening was 63 days. Based on the chest radiography findings, 71 students (1.6%) were suspected to have TB; however, further detailed examination confirmed that 19 students (0.4%) had active TB. This percentage is significantly higher than the 0.1% TB identification rate among residents in Osaka city of the same time period (P<0.001), which was also determined by chest radiography. The median age of the 19 TB positive patients was 23 years. Among them, 14 (73.7%) were male. The median time from the date of entry to Japan to the date of the chest radiography screening was 137 days. For 16 of those students, the entry to Japan was within 1 year of the radiography. Of the 19 TB positive patients, 16 (84.2%) did not have respiratory symptoms, 15 (79.0%) had sputum smear negative results, and 17 (89.5%) had no cavity. Health

    The Ministry of Education, Culture, Sports, Science and Technology of Japan started the Priority Assistance for the Formation of Worldwide Renowned Centers of Research - Global COE Program. This program is based on the competitive principle where a third party evaluation decides which program to support and to give priority support to the formation of world-class centers of research. Our program Center of Excellence for Advanced Structural and Functional Materials Design was selected as one of 13 programs in the field of Chemistry and Materials Science. This center is composed of two materials-related Departments in the Graduate School of Engineering: Materials and Manufacturing Science and Adaptive Machine Systems, and 4 Research Institutes: Center for Atomic and Molecular Technologies, Welding and Joining Research Institute, Institute of Scientific and Industrial Research and Research Center for Ultra-High Voltage Electron Microscopy. Recently, materials research, particularly that of metallic materials, has specialized only in individual elemental characteristics and narrow specialty fields, and there is a feeling that the original role of materials research has been forgotten. The 6 educational and research organizations which make up the COE program cooperatively try to develop new advanced structural and functional materials and achieve technological breakthrough for their fabrication processes from electronic, atomic, microstructural and morphological standpoints, focusing on their design and application: development of high performance structural materials such as space plane and turbine blades operating under a severe environment, new fabrication and assembling methods for electronic devices, development of evaluation technique for materials reliability, and development of new biomaterials for regeneration of biological hard tissues. The aim of this international conference was to report the scientific progress in our Global COE program and also to discuss

    After more than ten years of strategic investment research and development supported by government policies on science and technology, nanotechnology in Japan is making a transition from the knowledge creation stage of exploratory research to the stage of making the outcomes available for the benefit of society as a whole. Osaka University has been proactive in discussions about the relationship between nanotechnology and society as part of graduate and continuing education programs. These programs are intended to fulfill the social accountability obligation of scientists and corporations involved in R&D, and to deepen their understanding of the relationship between science and society. To meet those aims, the program has covered themes relating to overall public engagement relating to nanotechnology governance, such as risk management of nanomaterials, international standardization for nanotechnology, nanomeasurement, intellectual property management in an open innovation environment, and interactive communication with society. Nanotechnology is an emerging field of science and technology. This paper reports and comments on initiatives for public engagement on nanotechnology at Osaka University's Institute for NanoScience Design, which aims to create new technologies based on nanotechnology that can help realize a sustainable society.

    2006-12-01

    Ladies and Gentlemen On behalf of Yamada Science Foundation, I would like to extend our hearty welcome to all of you who are participating in the 60th Yamada Conference and International Symposium on Research in High Magnetic Fields particularly to those who have come a long way to Japan from various places all over the world. Yamada Science Foundation was founded in 1977 at Osaka, Japan. It develops its activities by giving support to the outstanding research projects in the basic natural sciences, especially in the interdisciplinary domains that bridge between well established research fields such as physics, chemistry, and biology. The Foundation also provides travel funds for scientists to visit or to go out of Japan in order to carry out international collaborative projects. It also holds conferences and workshops. Among these activities, one of the most important is the organization of Yamada Conferences, which are usually held two or three times a year on various topics which seem to be pioneering current research activities in natural sciences. Upon organizing Yamada Conferences, The Board of Directors of The Foundation put emphasis on the three symbolic English letter `I's. The first I stands for International, the second I means Interdisciplinary, and the third, perhaps the most important I symbolizes Innovative. As for this conference, I think it is in some sense interdisciplinary, because it deals with on one hand, the smallest scale of matter, the elementary particles while, on the other hand deals with the largest scale of matter, the universe, which are linked together. I also think many innovative ideas are presented in this conference. In this context, I believe this Conference is well suited to the scope of our Foundation. Another important aspect of holding Yamada Conference is to provide the forum of `Friendship' among the participants. We encourage all of you, particularly young scientists, to get acquainted with each other not only through hot

    High-resolution modeling approach is increasingly being considered as a necessary step for improving the monitoring and predictions of regional air quality. This is especially true for highly urbanized region with complex terrain and land-use. This study uses Community Multiscale Air Quality (CMAQ) model coupled with MM5 mesoscale model for a comprehensive analysis to assess the suitability of such high-resolution modeling system in predicting ozone air quality in the complex terrains of Osaka, Japan. The 1-km and 3-km grid domains were nested inside a 9-km domain and the domain with 1-km grid covered the Osaka region. High-resolution Grid Point Value-Mesoscale Model (GPV-MSM) data were used after suitable validation. The simulated ozone concentrations were validated and evaluated using statistical metrics using performance criteria set for ozone. Daily maxima of ozone were found better simulated by the 1-km grid domain than the coarser 9-km and 3-km domains, with the maximum improvement in the mean absolute gross error about 3 ppbv. In addition, 1-km grid results fared better than other grids at most of the observation stations that showed noticeable differences in gross error as well as correlation. These results amply justify the use of the integrated high-resolution MMS-CMAQ modeling system in the highly urbanized region, such as the Osaka region, which has complex terrain and land-use.

    Single amino acid mutations in amyloid-beta (Aβ) peptides can lead to early onset and increased severity of Alzheimer's disease. An example is the Osaka mutation (Aβ1-40E22D), which is more toxic than wild-type Aβ1-40. This mutant quickly forms early stage fibrils, one of the hallmarks of the disease, and these fibrils can even seed fibrilization of wild-type monomers. Using molecular dynamic simulations, we show that because of formation of various intra- and intermolecular salt bridges the Osaka mutant fibrils are more stable than wild-type fibrils. The mutant fibril also has a wider water channel with increased water flow than the wild type. These two observations can explain the higher toxicity and aggregation rate of the Osaka mutant over the wild type.

    Histamine food poisoning is caused by ingestion of spoiled fish containing high levels of histamine. This paper reports cases in which histamine was detected in Osaka prefecture in fiscal year 2015 in a survey of fish and fishery products on the market and the food poisoning. A suspected case of histamine food poisoning was also evaluated to investigate the cause and minimize further problems. Histamine in food was separated on SPE cartridge columns, and analyzed after derivatization with fluorescamine by means of HPLC-FL. Histamine was detected in some fishery products on the market and in food that had caused poisoning. The samples in which histamine was detected were semi-dried whole round herring (Urumeiwashi-maruboshi), mackerel (Saba) and sardine dumpling (Iwashi-tsumire). These foods were the main causes of histamine food poisoning according to the report of the Ministry of Health, Labour and Welfare, Government of Japan.

  17. Volcanic? Non-Volcanic? Low-Frequency Earthquakes beneath Osaka Bay - Event Search from Continuous Records -

    Aso, N.; Ide, S.

    2010-12-01

    Low frequency earthquakes (LFEs) and tremors are observed in Nankai subduction zone, Japan. They are recognized to occur upon the subducting Philippine Sea plate. On the other hand, LEFs apart from plate boundary surface are also known (e.g. Ohmi and Obara, 2002). Most of them are distributed around volcanoes with some exceptions. Ones of the exceptions are LEFs occurring beneath Osaka Bay area between Kinki and Shikoku regions. These LFEs occur near the extension of tremor belt in Shikoku, and they are also close to the tear of Philippine Sea plate between Kinki and Shikoku regions (Ide et al., GRL in press). In addition, the epicenters of these LFEs are aligned toward north-northwest, the direction of the tear, and its extended line passes through the epicenter of the 1995 Kobe Earthquake. These facts suggest the hidden relations between LFEs, the subducting slab, and major inland earthquakes. The waveforms of the LFEs beneath Osaka Bay often have distinct spectral peak around 2Hz, unlike LFEs in subduction zones. This feature is common to some volcanic tremors. It is also suggested that mantle-derived water is blowing off along the wake of the slab tear, and some fluid likely exists beneath Osaka Bay. The LFEs have been detected by routine analysis of the Japan Meteorological Agency (JMA). These are small portion of overall activities, because the routine analysis is not optimized to detect small low frequency events in noisy data. To figure out whole activities of LFEs, we apply Matched Filter Analysis (Gibbons and Ringdal, 2006; Shelly et al., 2007) to continuous waveform records, using LFEs detected by JMA as template events. We used the 69 components in the 23 stations in Hi-net, maintained by the National Reserch Institute for Earth Science and Disaster Prevention. The waveforms are bandpass filtered between 2 and 8Hz. We calculated the cross-correlations of template LFEs and continuous records with 8s time window. An LFE is detected when the cross

    This paper describes a methodology of PACS technology assessment and gives examples of the results of measurement of 24 items of PACS-related situations of image diagnosis systems in Osaka University Hospital before a PACS is installed. These data are to be compared with the data which will be measured after PACS is installed in the new Osaka University Hospital, in order to complete our technology assessment. We propose common variables, units, and conditions of measurement, in order to establish a standard method of data comparison between before and after PACS installation in hospitals at large. We designed our PACS taking technology assessment into account. We do not stop the technology assessment at the efficacy evaluation, because PACS must be more than a tool for radiological practice. We extend the technology assessment into the effectiveness evaluation, so that PACS is a part of radiological practice itself, and diagnostic accuracy, economy and efficiency are the results of PACS operation.

    We investigated the effect of balloon occluded arterial infusion of an anticancer agent (cisplatin/gemcitabine), used concomitantly with hemodialysis, which delivers an extremely high concentration of anticancer agent to the tumor site without systemic adverse effects, along with concurrent radiation (referred to as the Osaka Medical College regimen) in patients with advanced bladder cancer. A total of 329 patients (TisN0 16, T2N0 174, T3N0 77, T4N0 22 and TxN+ 40) were assigned to receive the Osaka Medical College regimen. Patients who did not achieve complete response underwent total cystectomy or secondary balloon occluded arterial infusion with an increased amount of cisplatin and/or gemcitabine. The Osaka Medical College regimen allowed 83.6% (276 of 329) of patients in total and 93.6% (250 of 267) of patients with organ confined disease (including T3b) to achieve complete response. Of the patients with a complete response 96% (240 of 250) survived with a functional bladder without evidence of recurrent disease within a mean followup of 159 weeks. Although lymph node involvement, especially N2 stage, was selected as a significant risk factor for treatment failure and survival, it was noteworthy that 61.9% of patients with N1 disease achieved complete response and that the 5-year overall survival rate was 72.2%. No patients had grade III or more severe toxicities. The Osaka Medical College regimen, a new bladder preservation strategy, can be curative not only in patients for whom cystectomy is indicated, but also in patients whose condition is not amenable to curative treatment because of disease stage, age or other factors, and for whom merely palliative therapy would otherwise seem the only option.

    The joint International Symposium RCBJSF-2014-FM&NT successfully has united two international events - 12th Russia/CIS/Baltic/Japan Symposium on Ferroelectricity (RCBJSF-12) and 9th International Conference Functional Materials and Nanotechnologies (FM&NT-2014). The RCBJSF symposium is a continuation of series of meetings on ferroelectricity, the first of which took place in Novosibirsk (USSR) in 1976. FM&NT conferences started in 2006 and have been organized by Institute of Solid State Physics, University of Latvia in Riga. In 2012 the International program committee decided to transform this conference into a traveling Baltic State conference and the FM&NT-2013 was organized by the Institute of Physics, University of Tartu, Estonia. In 2014 the joint international symposium RCBJSF-2014-FM&NT was organized by the Institute of Solid State Physics, University of Latvia and was part of Riga - 2014, the European Capital of Culture event. The purpose of the joint Symposium was to bring together scientists, students and high-level experts in solid state physics, materials science, engineering and related disciplines. The number of the registered participants from 26 countries was over 350. During the Symposium 128 high quality scientific talks (5 plenary, 42 invited, 81 oral) and over 215 posters were presented. All presentations were divided into 4 parallel sessions according to 4 main topics of the Symposium: Ferroelectricity, including ferroelectrics and multiferroics, pyroelectrics, piezoelectrics and actuators, integrated ferroelectrics, relaxors, phase transitions and critical phenomena. Multifunctional Materials, including theory, multiscale and multiphenomenal material modeling and simulation, advanced inorganic, organic and hybrid materials.

    The technique of laparoscopic liver resection (LLR) has been greatly improved since the first international consensus conference. Our aim was to evaluate the worldwide spread of LLR prior to the 2nd International Consensus Conference on Laparoscopic Liver Resection in Iwate, Japan (4-6 October 2014). The International Survey on Technical Aspects of Laparoscopic Liver resection was designed to assess dissemination of LLR, indications, and the surgical techniques. The anonymous questionnaire was e-mailed to liver surgeons worldwide. A total of 448 liver surgeons responded to the survey. The peak age range of surgeons performing LLR was 41-50 years. Japan had by far the largest number of respondents (n = 223), followed by the US (n = 38) and France (n = 20). In Japan, the majority of surgeons performing LLR belonged to community hospitals, where LLR has been increasingly used since its implementation in 2009 or later, comprising up to 40% of all liver resection cases. In contrast, in North America and Europe, LLR was mostly performed at academic medical centers. LLR has undergone global dissemination after the first international consensus conference in 2008. Japan has experienced unparalleled, explosive diffusion characterized by the adoption of LLR at middle-tier, regional institutions.

    This issue is published as the Proceedings of the 6th Edoardo Amaldi Conference on Gravitational Waves, held on 20-24 June 2005 at Bankoku Shinryoukan in Okinawa, Japan. Since the first Amaldi conference was held in Frascati in 1994, eleven years have passed and the scale of the conference has grown with the increasing activity in the field of gravitational waves. As the centenary celebration of Einstein's 'miracle year', 2005 was called 'World Year of Physics'. Among his breakthroughs published in 1905, the special theory of relativity is recognized as the most significant revolution in physics, completely changing our views concerning time and space. Ten years later, Einstein proposed the general theory of relativity, by which he predicted the existence of gravitational waves (GWs). At that time, it was only a dream to observe a GW because its effect was so small. Efforts to detect GWs, pioneered by Weber, have continued for almost 40 years, yet their detection remained a dream. However, the presentations at this conference have convinced us that it is no longer a dream. The GW detector projects have made extraordinary advances; in particular, the significant sensitivity improvement of LIGO and the completion of the VIRGO detector mark the beginning of the new era of GW physics. Firm developments in theories and source estimations were also reported. In particular, the data analysis session was very active and various discussions were held. Elaborate experimental techniques were presented, some of them already achieving the requirements for the next generation of detectors, such as Advanced LIGO and LCGT. In addition to the earth-based detectors, many presentations concerning space detectors were contributed; they indicated that space would become the new stage for GW physics and astronomy. This issue brings together the papers which were presented at this exciting conference. The proceedings comprise two volumes; the largest part is published as a volume of

    In Japan, huge passenger traffic moves through the Tokyo-Osaka corridor and the demand is mounting on one more high speed line besides the Tokaido Shinkansen. A magnetically levitated vehicle (JR Maglev) using superconducting magnets has been developed for the Tokyo-Osaka superspeed express. JR Maglev has many advantages over conventional rail systems. This paper describes the necessity of one more high speed line in this corridor, the reason the author chose Maglev, the scheme of this system, history of the development and outline of the new Yamanashi test line project.

    The three-dimensional velocity structure model for the Osaka sedimentary basin, southwest Japan is developed and improved based on many kinds of geophysical explorations for decades (e.g., Kagawa et al., 1993; Horikawa et al., 2003; Iwata et al., 2008). Recently, our project (Sekiguchi et al., 2013) developed a new three-dimensional velocity model for strong motion prediction of the Uemachi fault earthquake in the Osaka basin considering both geophysical and geological information by adding newly obtained exploration data such as reflection surveys, microtremor surveys, and receiver function analysis (hereafter we call UMC2013 model) . On April 13, 2013, an inland earthquake of Mw5.8 occurred in Awaji Island, which is close to the southwestern boundary of the aftershock area of the 1995 Kobe earthquake. The strong ground motions are densely observed at more than 100 stations in the basin. The ground motion lasted longer than four minutes in the Osaka urban area where its bedrock depth is about 1-2 km. This long-duration ground motions are mainly due to the surface waves excited in this sedimentary basin whereas the magnitude of this earthquake is moderate and the rupture duration is expected to be less than 5 s. In this study, we modeled long-period (more than 2s) ground motions during this earthquake to check the performance of the present UMC2013 model and to obtain a better constraint on the attenuation factor of sedimentary part of the basin. The seismic wave propagation in the region including the source and the Osaka basin is modeled by the finite difference method using the staggered grid solving the elasto-dynamic equations. The domain of 90km×85km×25.5km is modeled and discretized with a grid spacing of 50 m. Since the minimum S-wave velocity of the UMC2013 model is about 250 m/s, this calculation is valid up to the period of about 1 s. The effect of attenuation is included in the form of Q(f)=Q0(T0/T) proposed by Graves (1996). A PML is implemented in

    To identify medical and administrative revenue trends at a surgical center, for use in strategic planning, an off-line data processing system utilizing coding sheets was developed. Data on 66,402 surgical procedures performed at the Osaka University Hospital Surgical Center between 1966 and 1981 were processed to study trends in revenues. Trend analysis shows that (a) revenues at the surgical center have been increasing year by year; (b) technical charges, such as operation and anesthesia fees, have increased with each revision of the medical remuneration system of Japanese government health insurance; and (c) the length of time patients stay in the operating room has gradually increased.

    This is a case study for practical survey and assessment of urban landscapes containing outdoor advertisements in Osaka City, Japan. We practically surveyed and analyzed the colors used on the outdoor advertisements in the three urban areas: the business area long the main street, the amusement area along the shopping street, and the station plaza in front of the railroad terminal. Further by the laboratory experiments, we examined the interrelation between the atmosphere of the area and the impression arising from the outdoor advertisements using the pictures of street scenes on video monitor. In this experiment, eye movements of each subject observing the scene were analyzed by eye point recorder. (1) In general, vivid red, yellow, green and blue, and white and black were frequently used on the outdoor advertisements in every area. (2) The character of each area was respectively found out by analysis of the following factors: the type of advertisement, the size of each advertisement, and the arrangement of the advertisements. Vivid colors on the outdoor advertisements could be clearly perceived even from a distance. Then, our eyes would be attracted by vivid colors of them. (4) The atmosphere of the area would be affected by favorable or unfavorable impression from the outdoor advertisements. For instance, on the main street, the advertisements would impress us favorably if they are in harmony with each other and create an orderly and elegant streetscape. On the shopping street, various advertisements would impress us favorably if they create a lively and cheerful streetscape.

    To examine the current status and problems of resuscitation management in Japan as demonstrated at the 2006 and 2007 Osaka Senri medical rallies. Using manikins, the quality of resuscitation was evaluated in 33 teams that participated in the medical rallies. The challenge was to deliver defibrillation shocks for ventricular fibrillation; data were recorded using the Laerdal PC Skill Reporting System (Norway). The teams were first subjectively (visually) evaluated by a panel of judges and these evaluations were later reaffirmed using video records. An approximately 30s delay was observed between the time of contact and initiation of chest compression in the teams that adopted the American Heart Association (AHA) method compared with those that adopted the European Resuscitation Council (ERC) method. Although the overall quality of chest compressions was very good, in several instances, the hand positions were inappropriate and complete chest recoil was not achieved. The left paddle was incorrectly positioned by all teams. Only 15.8% of the teams were able to deliver shocks with less than 10s of interruption between the chest compressions. Regarding interruption of chest compressions at confirmation of correct tracheal tube placement, among the eight teams that adopted the AHA method, pauses of more than 10s were confirmed in five (62.5%). Significant differences in performance between the AHA and ERC methods were observed. The ERC guidelines were more rational and suitable in terms of actual application than the AHA guidelines.

    The DuraHeart left ventricular assist device (LVAD) is the world's first approved magnetically levitated implantable centrifugal pump. We report our initial experience with the DuraHeart as a bridge to heart transplantation. Between 2008 and 2011, 23 patients (17 males; mean age 35 years, range 16-53 years) with endstage heart failure underwent implantation with the DuraHeart LVAD at Osaka University Hospital. Of those, 7 underwent conversion surgery from a Nipro paracorporeal LVAD to the DuraHeart. There were no deaths during the mean support period of 559±241 days (176-999 days). In total, 17 patients (74%) remain with the LVAD and 5 (22%) underwent heart transplantation after 580±302 days (176-982 days) of support. Major adverse events included 8 (34%) driveline/pocket infections, 4 (17%) cerebrovascular accidents, 4 (17%) right heart failures requiring mechanical support, and 3 (13%) mechanical device failures (magnetic levitation failure caused by driveline fracture). Of the 5 patients who developed pump pocket infection, 3 underwent previous conversion surgery from the Nipro LVAD. Our initial experience with the DuraHeart LVAD in Japan demonstrated excellent long-term survival with acceptable rates of adverse events. With refinement of the system, including mechanical durability, this pump will further enhance the quality of life for patients who require long-term mechanical circulatory support.

    Osaka University Center for Twin Research is currently organizing a government-funded, multidisciplinary research project using a large registry of aged twins living in Japan. The purpose of the project is to collect various information as well as biological resources from registered twins, and to establish a biobank and databases for preserving and managing these data and resources. The Center is collecting data from twin pairs, both of whom have agreed to participate in a one-day comprehensive medical examination. The following data are being collected: physical data (e.g., height, body mass, blood pressure, theoretical visceral fat, pulse wave velocity, and bone density), data regarding epidemiology (e.g., medical history, lifestyle, quality of life, mood status, cognitive function, and nutrition), electrocardiogram, ultrasonography (carotid artery and thyroid), dentistry, plastic surgery, positron emission tomography, magnetoencephalogram, and magnetic resonance imaging of brain. These data are then aggregated and systematically stored in specific databases. In addition, peripheral blood is obtained from the participants, and then genomic DNA is purified and sera are stored. A wide variety of studies are ongoing, and more are in the planning stage.

    Whole-body cancer screening with multimodalities including [(18)F]-fluorodeoxyglucose positron emission tomography (FDG-PET) detects a wide range of tumors. This program has been recognized as an option for opportunistic screening, particularly in Japan. However, reports on diagnostic accuracy have been limited. We aimed to evaluate the detectability and related properties of this screening program among asymptomatic individuals in a community setting. The study participants were 1,762 residents of Osaka Prefecture, Japan, who underwent opportunistic cancer screening at Higashitemma Clinic for the first time between November 2004 and December 2005. FDG-PET cancer screening was performed with several imaging modalities (e.g., FDG-PET, computed tomography, magnetic resonance imaging and ultrasonography) and fecal occult blood test. Screening records were linked to the Osaka cancer registry within 1 year after the screening to determine sensitivity, specificity and positive predictive values. After excluding 12 participants with cancer detected before the screening, 33 were identified by the cancer registry to have primary cancers. Of these, the present screening program found that 28 were positive (6 prostate, 5 lung, 5 colorectal, 5 thyroid, 3 liver and 4 others). Sensitivity, specificity and positive predictive values were 84.8 % (28/33, 95 % confidence interval 69.1-93.3), 86.8 % (1,491/1,718, 85.1-88.3) and 10.1 % (28/277, 6.4-12.9), respectively. FDG-PET cancer screening with multimodalities reasonably and accurately detects existing asymptomatic cancer. However, the numbers of false negatives and false positives were not insignificant. Facilities that provide the screening should inform participants of relevant information, including the limitations of this program.

    The 2011 great Tohoku earthquake (Mw 9.0) occurred on March 11, 2011, and the largest aftershock (Mw 7.7) at the region adjacent to south boundary of the mainshock's source region. Long-period ground motions (1-10s) of large amplitude were observed in the Osaka sedimentary basin about 550-800km away from the source regions during both events. We studied propagation and site characteristics of these ground motions, and found some common features between these two events in the Osaka basin. (1) The amplitude of horizontal components of the ground motion at the site-specific period is amplified at each sedimentary station. The predominant period is around 7s in the bayside area where the largest pSv were observed. (2) The velocity Fourier spectra have their peak values around 7s at the bedrock sites surrounding the Osaka basin. (3) Two remarkable wave packets separated by 30s propagating from stations around the Nobi plain to the bedrock sites near the Osaka basin were seen in the pasted-up velocity waveforms from the source regions to the Osaka basin for both events (Sato et al., 2012). Therefore, large long-period ground motions in the Osaka basin are generated by the combination of propagation-path and basin effects. Firstly, we simulate ground motions due to the largest aftershock using three-dimensional FDM (GMS; Aoi and Fujiwara, 1999). The reason we focus on the largest aftershock is that this event has a relatively small rupture area and simple rupture process compared to the mainshock. The source model is based on the model estimated by Kubo et al. (2013). The velocity structure model is a three-dimensional velocity structure based on the Japan Integrated Velocity Structure Model (Koketsu et al., 2012) and the layer of Vs 350m/s in this model is replaced with one of Vs 500m/s. The minimum effective period in this computation is 3s. Then, we compare synthetic waveforms with observed ones. At CHBH14, the nearest station to the source and 60km away from the

    Conference logo The 21st century has been called the century of environmental revolution. Green innovations and environmentally friendly production systems based on physics, chemistry, materials science, and electronic engineering will be indispensable for ensuring renewable energy and establishing a sustainable society. In particular, production design, materials processing, and fabrication technologies such as welding and joining will be very important components of such green innovations. For these reasons, the International Symposium on Materials Science and Innovation for Sustainable Society - eco-materials and eco-innovation for global sustainability - (ECO-MATES 2011) was organized by the Joining and Welding Research Institute (JWRI) and the Center of Environmental Innovation Design for Sustainability (CEIDS), Osaka University. ECO-MATES 2011 was held at Hotel Hankyu Expo Park, Osaka, Japan from 28-30 November 2011. 435 participants from 20 countries around the world attended the symposium. 149 oral presentations including 60 invited talks and 160 posters were presented at the symposium to discuss the latest research and developments in green innovations in relation to environmental issues. The topics of the symposium covered all environmentally related fields including renewable energy, energy-materials, environment and resources, waste and biomass, power electronics, semiconductor, rare-earth metals, functional materials, organic electronics materials, electronics packaging, smart processing, joining and welding, eco-efficient processes, and green applied physics and chemistry. Therefore, 55 full papers concerning green innovations and environmentally benign production were selected and approved by the editorial board and the program committee of ECO-MATES 2011. All papers were accepted through peer review processes. I believe that all the papers have many informative contents. On behalf of the steering committee of the symposium, I would like to express

    The International Conference on Highly Frustrated Magnetism 2008 (HFM2008) took place on 7-12 September 2008 at the Technische Universität Carolo-Wilhelmina zu Braunschweig, Germany. This conference was the fourth event in a series of meetings, which started in Waterloo, Canada (HFM 2000), followed by the second one in Grenoble, France (HFM 2003), and the third meeting in Osaka, Japan (HFM 2006). HFM2008 attracted more than 220 participants from all over the world. The number of participants of the HFM conference series has been increasing steadily, from about 80 participants at HFM 2000, to 120 participants at HFM 2003, and 190 participants at HFM 2006, demonstrating that highly frustrated magnetism remains a rapidly growing area of research in condensed matter physics. At the end of HFM2008 it was decided that the next International Conference on Highly Frustrated Magnetism will be held in Baltimore, USA in 2010. HFM2008 saw four plenary talks by R Moessner, S Nakatsuji, S-W Cheong, and S Sachdev, 18 invited presentations, 30 contributed talks and about 160 poster presentations from all areas of frustrated magnetism. The subjects covered by the conference included: Kagome systems Itinerant frustrated systems Spinels and pyrochlore materials Triangular systems Unconventional order and spin liquids Chain systems Chain systems Novel frustrated systems This volume of Journal of Physics: Conference Series contains the proceedings of HFM2008 with 83 papers that provide a scientific record of the scientific topics covered by the conference.

    This article examines the effects of language use on explicit and implicit attitudes. We employed the matched-guise technique to measure participants' impressions of standard-Japanese and Osaka-dialect speakers. Implicit attitudes were assessed by the Implicit Association Test (IAT). The Osaka-dialect speaker was evaluated as warmer than the standard-Japanese speaker, suggesting that explicit attitudes toward the Osaka dialect have changed positively. On the other hand, the results for the impression of intelligence were consistent with the previous literature that the standard-Japanese speaker was seen as more intelligent than the Osaka-dialect speaker. Compared with explicit attitudes, the analyses of implicit attitudes revealed that participants showed a consistent implicit bias favoring standard-Japanese language use. The changing processes and relationships of explicit and implicit attitudes were discussed.

    Importance Dry eye disease has become an important health problem. A lack of concordance between self-reported symptoms and the outcome of dry eye examinations has raised questions about dry eye disease. Objective To explore the association between subjective happiness and objective and subjective symptoms of dry eye disease. Design The study adopted a cross-sectional design. Setting All the employees of a company in Osaka, Japan. Participants 672 Japanese office workers using Visual Display Terminals (age range: 26–64 years). Methods The dry eye measurement tools included the Schirmer test, conjunctivocorneal staining, the tear film break-up time, as well as the administration of a dry eye symptoms questionnaire. Happiness was measured by the Subjective Happiness Scale. Main Outcome Measures Dry eye examination parameters, dry eye symptoms questionnaires, and the Subjective Happiness Scale score. Results Of the 672 workers, 561 (83.5%) completed the questionnaires and examinations. The mean Subjective Happiness Scale score was 4.91 (SD = 1.01). This score was inversely correlated with the dry eye symptom score (r = -0.188, p < 0.001), but was not associated with objective findings which include conjunctivocorneal staining, low Schirmer test score, or low tear film break-up time. The level of subjective happiness was the lowest in the group without objective results, but reported subjective symptoms of dry eyes (p < 0.05). Conclusions and Relevance There is evidence of the relationship between subjective happiness and self-reported symptoms of dry eyes. Findings of this study revealed a new perspective on dry eye disease, including the potential for innovative treatments of a specific population with dry eye disease. PMID:25830665

    Approximately 400 years ago, Dutch physicians laid the foundations for Western medicine in Japan. Around 1860, Dutch naval surgeons, trainees of the College of Army Surgeons in Utrecht, were to become the founders of the Medical Faculties at the Universities of Nagasaki, Tokyo and Osaka. The earlier Deshima-settlement surgeons Engelbert Kaempfer and Philipp Franz von Siebold played a highly important role in our knowledge of Japan during the 18th and 19th centuries.

    The authors have been developing an electrohydraulic total artificial heart with a basic concept placing the blood pumps and an electrohydraulic energy converter separately, in the thorax and the abdominal region, respectively, to minimize anatomic constraints. Major problems of the system were a high energy consumption of 56 W at 6 L/min output and an insufficient maximum output of 6.7 L/min. The energy converter was redesigned to overcome these problems. A three phase, 4 pole brushless DC motor, which has maximum efficiency of 79% at a motor rotation of 2500 rpm with a load of 0.1 Nm, was developed for the new energy converter. Flow-channel design of the regenerative oil pump was optimized, which resulted in increasing the maximum flow rate at one directional motor rotation from 18 to 29 L/min. In vitro performance of the electrohydraulic total artificial heart was evaluated in a mock circulation with physiologic pressure conditions. Maximum output was increased to 10.7 L/min at a pump rate of 120 bpm and energy consumption of the motor at 6 L/min output was reduced to 18 W. Based upon these favorable results, the system is now being assembled for chronic animal implantation.

    The advent of scanning probe microscopy (SPM) in the 1980s has significantly promoted nanoscience and nanotechnology. In particular, non-contact atomic force microscopy (NC-AFM), one of the SPM family, has unique capabilities with high spatial resolution for nanoscale measurements in vacuum, air and liquids. In the last decade we have witnessed the rapid progress of NC-AFM with improved performance and increasing applications. A series of NC-AFM international conferences have greatly contributed to this field. Initiated in Osaka in 1998, the NC-AFM meeting has been followed by annual conferences at Pontresina, Hamburg, Kyoto, Montreal, Dingle, Seattle and Bad Essen. The 9th conference was held in Kobe, Japan, 16-20 July 2006. This special issue of Nanotechnology contains the outstanding contributions of the conference. During the meeting delegates learnt about a number of significant advances. Topics covered atomic resolution imaging of metals, semiconductors, insulators, ionic crystals, oxides, molecular systems, imaging of biological materials in various environments and novel instrumentation. Work also included the characterization of electronic and magnetic properties, tip and cantilever fabrication and characterization, atomic distinction based on analysis of tip-sample interaction, atomic scale manipulation, fabrication of nanostructures using NC-AFM, and related theories and simulations. We are greatly impressed by the increasing number of applications, and convinced that NC-AFM and related techniques are building a bridge to a future nano world, where quantum phenomena will dominate and nano devices will be realized. In addition, a special session on SPM road maps was held as a first trial in the field, where the future prospects of SPM were discussed enthusiastically. The overall success of the NC-AFM 2006 conference was due to the efforts of many individuals and groups with respect to scientific and technological progress, as well as the international

    The onset of acute myocardial infarction (AMI) shows characteristic circadian variations; that is, a definite morning peak related to biologic rhythms and a vague nighttime peak related to socioeconomic factors. The recent economic recession in Japan may change the circadian variation, especially the nighttime peak. This study evaluated the recent circadian variation of AMI in Osaka and specified the patient subgroups showing either a morning or nighttime peak predominantly. Of 1,609 consecutive patients with AMI registered from April 1998 to January 2000, 1,252 whose onset of AMI was definitely identified were studied. The day was divided into six 4-h periods with a morning peak between 08.01 h and 12.00h, and nighttime peak between 20.01 h and 24.00h. When subgroup analysis was performed, female patients aged 65 years or more showed a morning peak alone and male patients aged less than 65 years with an occupation and the habits of cigarette smoking and alcohol intake showed a nighttime peak alone. Thus, in Osaka nighttime socioeconomic factors may currently be more potent triggers of AMI than the morning surges in younger male workers who smoke and drink.

    It is known that local spatially and temporally resolved measurements of atmospheric aerosols in Asian urban city are meaningful since the aerosol distribution in East-Asia is complicated due to the increasing emissions of anthropogenic aerosols in association with economic growth and natural dust significantly varies with the seasons. In this work, we intend to show the spatial and temporal variation of atmospheric aerosols in East Asia, especially around AERONET/Osaka site and Dragon-Asia period, named "DRAGON-Osaka". AERONET (Aerosol Robotics Network) Osaka site was established in 2002 in the campus of Kinki University. Nowadays, LIDAR, PM2.5 / 10 measurements and others are available. The site data are useful for algorithm development of aerosol retrieval over busy city. However, human activities in this region also emit the huge amount of pollutions, thus it is needed to investigate the local distribution of aerosols in this region. In March 2012, to obtain maximum efficiency of DRAGON-Osaka, several Cimels are deployed at more sites as soon as possible. In order to investigate change of aerosol properties, PM-individual analysis is made with scanning electron microscope (SEM) coupled with energy dispersive X-ray analyzer (EDX). A componential analysis presents temporal variation of aerosol properties.

  3. Women's health in Japan.

    PubMed

    1994-08-01

    In Japan, the Women's Center in Osaka operates a women's health information hotline for 3 days/month. An analysis of 730 calls to the Centre during 1990-1992 shows that abortion and contraception are not major concerns. (Safe abortion is accessible. Oral contraceptives are banned. Condoms and the rhythm method are the most common family planning methods.) The bulk of the calls (22.6%) centered around menstruation, followed by reproductive diseases (21.5%), menopause (7%), and infertility (7%). Irregular menstruation, no menstruation, and painful periods made up most menstruation concerns. These cases tended not to be serious, which explains why physicians were not interested in them, resulting in client dissatisfaction. Physicians are usually concerned about menstruation only as it pertains to desire for pregnancy. Mothers who call the hotline with questions about their daughters' menstruation ask about menstruation as it relates to fertility. Clearly, woman's role is to bear children. Physicians prescribe medication to women with concerns about infertility but women have difficulty asking their physicians any questions about the medication. Women concerned about infertility do not consider other options such as alternative treatments, adoption, or not bearing children. Once fertility has diminished, physicians are no longer interested in women. Women with questions about menopause who do not get the information from their physician or respectful attention from their physician call the hotline. Most menopause- related complaints revolve around symptoms.

    Japan continues to be a major player in stem cell biology and related fields, boasting multiple world-class programs in a broad spectrum of stem cell studies, a permissive regulatory framework, an active society for regenerative medicine and a growing industry involvement. The most noted work in recent years has of course originated in the laboratory of Shinya Yamanaka, with the first report of induced pluripotent stem cells (iPS cells) in 2006, and numerous technical advancements since, which prompted the government to establish a Center for iPS Cell Research and Application in 2010 (see below). Additional concentrations of stem cell research excellence can be found in Tokyo, Osaka, Kobe and Kumamoto. In 2011, Yoshiki Sasai's laboratory in the RIKEN Center for Developmental Biology, Kobe, achieved another remarkable result in inducing optic cup-like structures from embryonic stem cells using 4D tissue culture techniques, building on previous work in which the group had generated stratified cerebral cortex-like tissue from embryonic stem cells in vitro.

    The rates of tuberculosis remain high in urban areas. The declining speed of tuberculosis incidence rate in urban areas has been slower than other areas. Efforts and resources to tuberculosis control must be concentrated on urban locations to eradicate tuberculosis in Japan. 1. Tuberculosis control in a public health center of urban area: Teru OGURA and Chiyo INOGUCHI (Toshima City, Ikebukuro Public Health Center, Tokyo Metropolitan) A wide range of TB control measures is implemented by public health centers, such as a patient registration, home-visit guidance, contact examination in urban areas. Directors of every health center have the direct responsibility for tuberculosis control measures in their jurisdiction. Ikebukuro is urban areas where there are many offices, shopping and amusement facilities. Urban people is often on the move looking for job, so public health centers are often not easy to carry out contact examinations as planned. In recent years, homelessness has been recognized as a growing urban social problem. Their incidence of tuberculosis is high. Special TB control program must be carried out in urban areas. 2. Tuberculosis Control in Tokyo Metropolitan: Kazumasa MATSUKI (Department of Infectious Diseases and Tuberculosis, Bureau of Public Health, Tokyo Metropolitan) There has been a steady decline in the TB wards. The beds for TB patients are running short and even smear positive TB cases cannot be put in a hospital without waiting several days. Staffs of an urban emergency department must protect tuberculosis infection by environmental controls of emergency room. Tokyo Metropolitan government supports the engineering improvements of emergency room to hospitals. Directly observed therapy for tuberculosis patients at a district has been implemented to complete their therapy. On DOT, a trained health worker observes the patient take anti-TB medication. 3.

    The aim was to give on overview of the profile of cardiovascular disease, vascular pathology and the relationships between lifestyle and cardiovascular disease in Japanese. Compared with the United States and Europe, the higher mortality from stroke and lower mortality from coronary heart disease constitute a unique cardiovascular profile for Japan. A selective review of population-based pathology, trend and prospective cohort studies was performed to clarify the characteristics of cardiovascular disease and vascular pathology, trends in the incidence and mortality of cardiovascular disease, and the relationships between lifestyle and cardiovascular disease among Japanese adults. Since the 1970s, mortality from coronary heart disease as well as stroke has declined substantially in Japan, probably due to a major decline in blood pressure levels and for men a more recent decline in smoking, in spite of an increase in body mass index and total cholesterol levels. However, the decline in mortality was smaller and plateaued in middle-aged men aged 30-49 in the metropolitan cities of Tokyo and Osaka. The incidence of coronary heart disease has increased among middle-aged men residing in the suburbs of Osaka. As for the associations between lifestyle and cardiovascular disease, higher sodium, lower calcium and lower animal protein content in the diet and for men higher alcohol consumption may account for the higher prevalence of hypertension and higher risk of stroke for Japanese than for western populations. On the other hand, lower saturated fat (meat) and higher n3 polyunsaturated fat (fish) in the Japanese diet may contribute to the lower prevalence of hypercholesterolemia and lower risk of coronary heart disease among Japanese. Japan is unique among developed countries in that coronary heart disease mortality has been low and has continued to decline, while stroke mortality has declined substantially. However, a recent trend for coronary heart disease incidence to

    In Japan, ambulance staffing for cardiac arrest responses consists of a 3-person unit with at least one emergency life-saving technician (ELST). Recently, the number of ELSTs on ambulances has increased since it is believed that this improves the quality of on-scene care leading to better outcomes from out-of-hospital cardiac arrest (OHCA). The objective of this study was to evaluate the association between the number of on-scene ELSTs and OHCA outcome. This was a prospective cohort study of all bystander-witnessed OHCA patients aged ≥ 18 years in Osaka City from January 2005 to December 2007 using on an Utstein-style database. The primary outcome measure was one-month survival with favorable neurological outcome defined as a cerebral performance category ≤ 2. Multivariable logistic regression model were used to assess the contribution of the number of on-scene ELSTs to the outcome after adjusting for confounders. Of the 2408 bystander-witnessed OHCA patients, one ELST group was present in 639 (26.5%), two ELST were present in 1357 (56.4%), and three ELST group in 412 (17.1%). The three ELST group had a significantly higher rate of one-month survival with favorable neurological outcome compared with the one ELST group (8.0% versus 4.5%, adjusted OR 2.26, 95% CI 1.27-4.04), while the two ELST group did not (5.4% versus 4.5%, adjusted OR 1.34, 95% CI 0.82-2.19). Compared with the one on-scene ELST group, the three on-scene ELST group was associated with the improved one-month survival with favorable neurological outcome from OHCA in Osaka City.

    The Institute of Free-Electron Laser (iFEL) was established in April 2000 at Osaka University. The facility was constructed by the Free-Electron Laser Institute corporation (FELI) from 1992 to 1997. FELI demonstrated lasing in the spectral range from 0.28 to 20 μm. Efforts are still being made by Osaka University in order to extend the lasing range. In the operational period from April 2001 to March 2002, mid-infrared light of 5-20 μm was supplied for over 40 cooperative research programs on fields of semiconductor, bio-medical and environmental chemistry. An effort is ongoing to improve the property of the light. In this paper, the status of iFEL and some biomedical applications research are described.

    2017-07-01

    Despite being 770 km away from the epicenter, observed ground motions due to the Tohoku earthquake in the Osaka Basin were unexpectedly large, with an amplification of more than a factor of 20 compared to immediately outside the basin, and including 2.7 m peak-to-peak roof displacements at one high-rise building. The local ground motions exceeded expectations based on standard computations of site response by a factor of 3, predicted frequencies of peak acceleration were off by at least 50%, and such discrepancies have not yet been explained quantitatively. Here we show that utilizing semianalytic theory for surface-wave amplification, we are able to accurately predict both the amplitudes and frequencies of large ground amplification in the Osaka Basin using only knowledge of the local one-dimensional structure. Comparison between this simple prediction and observed amplification was not expected to be so favorable and suggests that simple one-dimensional surface-wave site amplification factors can be useful in the absence of full three-dimensional wave propagation simulations. Such surface-wave amplification factors can be included in addition to the standard measures of site-specific site amplification and should help explain strong ground motion variability in future large earthquakes that shake Osaka Basin and elsewhere in the world.

    To ascertain nosocomial tuberculosis (TB) infection control practice in hospitals in Osaka City. A questionnaire was distributed in the orientation meeting and collected at the occasion of medical inspection in all 196 hospitals in Osaka City in 2003. TB patients were diagnosed in about half of hospitals in the past 3 years. Basic TB infection control measures were taken in the majority of hospitals; such as chest X-ray screening for all inpatients, health check for employees, tuberculin skin test (TST) for newly employed staff, and nomination of a person in charge of TB infection control. Control measures were practiced more often in hospitals where TB patients were diagnosed, such as "fiberoptic bronchoscopy is to be conducted last in the working hours to avoid contamination of TB bacilli in a room," "TST (including two-step method) for all newly employed staff," "Staff wear N95 mask when they deal with TB patients/suspects," and the differences were statistically significant. It is necessary in hospitals in Osaka City to strengthen nosocomial TB infection control as TB patients were diagnosed in about half of hospitals in the past 3 years. Low cost infection control measures were undertaken more often among hospitals where TB patients were diagnosed. Introduction of high cost equipment or improvement of facilities should be considered in hospitals of high TB risk. Guidelines formulated based on analysis of the survey should facilitate all hospitals to introduce at least low cost effective tuberculosis infection control measures.

    The objective of this study was to compare the temporal trends in survival after out-of-hospital cardiac arrest (OHCA) between two large metropolitan communities in Asia and evaluate the factors affecting survival after OHCA. A population-based prospective observational study. The Cardiovascular Disease Surveillance (CAVAS) project in Seoul and the Utstein Osaka Project in Osaka. A total of 36,292 resuscitation-attempted OHCAs with cardiac aetiology from 2006 to 2011 in Seoul and Osaka (11,082 in Seoul and 25,210 in Osaka). The primary outcome was neurologically favourable survival. Trend analysis and multivariable Poisson regression models were conducted to evaluate the temporal trends in survival of two communities. During the study period, the overall neurologically favourable survival was 2.6% in Seoul and 4.6% in Osaka (p<0.01). In both communities, bystander cardiopulmonary resuscitation (CPR) rates increased significantly from 2006 to 2011 (from 0.1% to 13.1% in Seoul and from 33.3% to 41.7% in Osaka). OHCAs that occurred in public places increased in Seoul (12.5% to 20.1%, p for trend <0.01) and decreased in Osaka (13.5% to 10.5%, p for trend <0.01). The proportion of OHCAs defibrillated by emergency medical service (EMS) providers was only 0.4% in 2006 but increased to 17.5% in 2011 in Seoul, whereas the proportion in Osaka decreased from 17.7% to 13.7% (both p for trend <0.01). Age-adjusted and gender-adjusted rates of neurologically favourable survival increased significantly in Seoul from 1.4% in 2006 to 4.3% in 2011 (adjusted rate ratio per year, 1.17; p for trend <0.01), whereas no significant improvement was observed in Osaka (3.6% in 2006 and 5.1% in 2011; adjusted rate ratio per year, 1.03; p for trend=0.08). Survivals after OHCA were increased in Seoul while remained constant in Osaka, which may have been affected by the differences and improvements of patient, community, and EMS system factors.

  14. Paleo-stress and temperatures based on calcite twin and vitrinite reflectance in the Nojima Fault, SW Japan

    NASA Astrophysics Data System (ADS)

    Oosono, N.; Furuta, K.; Sakaguchi, A.

    2016-12-01

    The seismogenic fault must experience rupture propagation and frictional slip during earthquakes. The record of this process can be estimated from heat and stress records at principal shear zone of fault. In recent, some methods were developed to detect heat and stress from fault rocks. The organic materials in sediment are delicate with heating to be sensitive geo-thermometer. The vitrinite reflectance and Raman spectra analysis were applied for detection of fault heating. The mechanical twin of calcite depends on shear stress, and twin density method is proposed to estimate paleo-stress for fault rock in brittle regime. The Nojima Fault develops at Awaji Island SW Japan is the seismogenic fault of the 1995 Kobe earthquake. The Nojima Fault strikes northeast - south west and bounds Ryoke Granite and Pleistocene Osaka Groups. The Ryoke Granite thrusts up the Osaka Group and suffers deformation more than several ten meters. This damage zone is characterized by brittle failure, and some cracks are filled with fine calcite minerals. The Osaka Group is composed of a sandstone and silt layers, and contacts with Ryoke Granite at silt layer. The fault related folds are observed around the fault zone, and some granite blokes are scattered within the Osaka Group . In micro structure, possible principal shear zone of narrow dark seem of 5 mm in thickness is developed within the silt layer of the Osaka Group. Some coal laminas are included in the Osaka Group, and the vitrinite reflectance was approximately 0.2%. The estimated paleo-temperature of the host rock is approximately several ten degrees. Such low temperature of the sediment must be obtained shallow burial depth, and the sediment may record recent fault activity. Low temperature host rock can detect small signal of frictional heat.

    Temperature changes at the ground surface propagate into the underground and disturb the subsurface temperature structure. Analyzing disturbances in the subsurface temperature structure, we can reconstruct the past ground surface temperature (GST) change, which is closely related to the past surface air temperature change. This method can be applied to studies of thermal environment evolution in urban areas such as the development of "heat islands". We have been investigating GST histories in three areas, which are located in Japan and Thailand. The three areas are the northern part of Kanto area, Osaka area, and Bangkok area. Kanto area and Osaka area have the greatest and second greatest population in Japan, each other. Bangkok area has the greatest population in Thailand. In the northern part of Kanto area, we conducted measurements of temperature profiles in groundwater monitoring wells at 25 sites in 2009, 2010, and 2011. In Osaka area, temperature profiles were measured at 31 sites in 2011 as the project of the Sumitomo Foundation (M. Taniguchi). In Bangkok area, we measured temperature profiles at 45 sites in 2004, 2006, 2008, and 2010. We examined the shapes of the temperature profiles and selected ones that are not significantly disturbed by groundwater flow. Reconstruction of GST history for the last about 300 hundred years was made at two sites in the northern part of Kanto area, at six sites in Osaka area, and at six sites in Bangkok area. We used a multi-layer model that allows layers with different thermal properties, determining layer boundaries based on lithology of the formations around the wells. All of the reconstructed GST histories show surface warming in the last century. In the northern part of Kanto area, the amount of the temperature increase from 1700 to 2010 is about 2.5 K at both sites. In Osaka area, the amount of the temperature increase from 1700 to 2010 ranges from 2.5 K to 5.0 K and is larger in the city center and the southern part

    To examine and analyze the spread of measles in Osaka in 2014 and determine effective measures to prevent such occurrences. We analyzed 47 cases of measles reported in Osaka, including one measles patient living in another prefecture where there was an outbreak. We focused on age distribution, the number of patients reported each week, estimated infection routes, history of measles vaccination, detection of viruses, and number of days it took to report the case after the onset of measles. Patients aged 20-39 years accounted for 24 cases (51.1%). The number of patients reported started from 2nd week with relatively broad peak to 27(th) week, and the measles epidemic was brought under control in the 47(th) week. Among the 47 cases, no source could be identified in 16 cases (34.0%). Household exposure was the main cause of the infection (25.5%), followed by imported cases (21.3%). Eighty-three percent of the overall patients had not received a measles vaccination at all or it was unclear whether they previously had been vaccinated. Genotype B3, H1, and D8 were detected in our patients and these genotypes originated overseas. It took significantly more days, from the onset of measles, for the case to be reported in patients aged 15 years and over compared with those aged under 15 years (P=0.001). For eradicating measles in Osaka, it is important to raise awareness about this issue among medical institutions, especially institutions for adults, in order for them to report cases as soon as possible, upon discovery in their patients. In addition, "catch-up" supplementary immunizations are effective for all people, including adults who are susceptible to measles.

    The Fifth International Conference on Inertial Fusion Sciences and Applications (IFSA 2007) was held on 9-14 September 2007 at Kobe International Conference Center in Kobe, Japan. The host organizations for this conference were Osaka University and the Institute of Laser Engineering (ILE) at Osaka University; and co-organized by the Institute Lasers and Plasmas (ILP) in France, the Commissariatá l'Energie Atomique (CEA), Lawrence Livermore National Laboratory (LLNL), National Institute for Fusion Science (NIFS) in Japan, and Kansai Photon Science Institute (KPSI), Japan Atomic Energy Agency (JAEA). The conference objective was to review the state of the art of research in inertial fusion sciences and applications since the last conference held in Biarritz, France, in 2005. 470 abstracts were accepted, and 448 persons from 18 countries attended the conference. These Proceedings contain 287 of the papers presented at IFSA 2007. This collection of papers represents the manuscripts submitted to and passing the peer review process. The program was organized with some specific features: The reviews of influential programs appeared both at the very beginning and at the very end of the Conference to attract attendance throughout the Conference. Each poster session had the same time period as a single oral session, thereby avoiding overlap with oral talks. The everyday program was structured to be as similar as possible so the attendees could easily recognize the program. With a goal of achieving inertial fusion ignition and burn propagation in the laboratory, researchers presented the exciting advances in both traditional hot spot ignition and fast ignition approach, including status report of USA's National Ignition Facility (NIF), French Laser Magajoule (LMJ), Japanese Fast Ignition Realization Experiment (FIREX), and European High Power laser Energy Research (HiPER). A particular emphasis of the meeting was that the `physics of inertial fusion' category was dominated

    The M9.0 great earthquake that occurred on March 11, 2011 triggered a huge tsunami on the Pacific coast in the Tohoku region and caused enormous damage, resulting in 15,854 deaths and 3,276 missing persons (as of March 1, 2012, according to the Japanese National Police Agency). Presently, inhabitants in Fukushima Prefecture continue to live as refugees because of radiation contamination caused by explosions at the Fukushima nuclear power plants. Immediately after the earthquake, DMATs (Disaster Medical Assistance Teams) went to the affected areas to begin relief operations. The Japan Medical Association then founded the JMAT (Japan Medical Association Team), an organization to take over DMAT activities. The purpose of JMAT is (1) to assist hospitals and clinics in affected areas with daily care and (2) to provide medical care in refuge and aid stations. The Osaka Medical Association was assigned to be in charge of medical support in Iwate Prefecture. For medical services, team activities are more effective than individual efforts. Therefore, JMAT is basically a team composed of one doctor, two nurses, and one clerical officer. The team of Yao Municipal Hospital consists of two doctors, two nurses, two pharmaceutical chemists, and two office clerks. It is 13,000 km each way from Osaka to Iwate, and it is an estimated 15 hours by road. Our initial schedule was five days and four nights, leaving Osaka on the afternoon of May 26 and heading for Iwate on a chartered bus, engaging in medical care from the morning of May 27 to 30, leaving Iwate on the morning of May 30 and returning to Osaka that evening. However, since Hanamaki Airport in the inland area of Iwate Prefecture became usable starting in mid-May, we arrived in Hanamaki City by air and used a large taxi from the airport. In accordance with the recovery of local medical institutions, the Osaka Medical Association JAMT dispatch was to be terminated by the end of May. As a result, our team's itinerary was reduced

  13. PREFACE: ISEC 2005: The 10th International Superconductive Electronics Conference

    The 10th International Superconductive Electronics Conference took place in Noordwijkerhout in the Netherlands, 5-9 September 2005, not far from the birthplace of superconductivity in Leiden nearly 100 years ago. There have been many reasons to celebrate the 10th ISEC: not only was it the 20th anniversary, but also the achievements since the first conference in Tokyo in 1987 are tremendous. We have seen whole new groups of superconductive materials come into play, such as oxide superconductors with maximum Tc in excess of 100 K, carbon nanotubes, as well as the realization of new digital concepts from saturation logic to the ultra-fast RSFQ-logic. We have learned that superconductors not only show s-wave symmetries in the spatial arrangement of the order parameter, but also that d-wave dependence in oxide superconductors is now well accepted and can even be successfully applied to digital circuits. We are now used to operating SQUIDs in liquid nitrogen; fT sensitivity of SQUID magnetometers is not surprising anymore and can even be reached with oxide-superconductor based SQUIDs. Even frequency discriminating wide-band single photon detection with superconductive devices, and Josephson voltage standards with tens of thousands of junctions, nowadays belong to the daily life of advanced laboratories. ISEC has played a very important role in this development. The first conferences were held in 1987 and 1989 in Tokyo, and subsequently took place in Glasgow (UK), Boulder (USA), Nagoya (Japan), Berlin (Germany), Berkeley (USA), Osaka (Japan), Sydney (Australia), and in 2005 for the first time in the Netherlands. These conferences have provided platforms for the presentation of the research and development results of this community and for the vivid discussion of achievements and strategies for the further development of superconductive electronics. The 10th conference has played a very important role in this context. The results in laboratories show great potential and

    The purpose of this study was to prospectively investigate the association between infant feeding practices and the development of early childhood caries (ECC). Subjects were 315 children. Information about the variables under study and potential confounding factors were obtained by questionnaire during pregnancy and when the children were two to nine, 16 to 24, 29 to 39, and 41 to 49 months old. Outcome data were collected at 41 to 50 months old. Children were classified as having ECC if one or more primary teeth had decayed or been filled. Compared with breast-feeding for six months or fewer, breast-feeding for 18 months or longer tended to be positively associated with a risk of ECC, and a U-shaped relationship was observed. Use of a bottle to drink sweetened liquids other than milk and the introduction of solid foods at six months old or later were positively associated with a risk of ECC. There was no significant association between bottle-feeding while falling asleep at night and the risk of ECC. Prolonged breast-feeding, bottle use for sweetened liquids other than milk, and the introduction of solid foods at six months old or later might be risk factors for the development of dental caries.

    Maternal nutritional status during pregnancy is an important determinant of fetal growth. Although the effects of several nutrients and foods have been well examined, little is known about the relationship of overall maternal diet in pregnancy to fetal growth, particularly in non-Western populations. We prospectively examined the relationship of maternal dietary patterns in pregnancy to neonatal anthropometric measurements at birth and risk of small-for-gestational-age (SGA) birth among 803 Japanese women with live-born, singleton, term deliveries. Maternal diet in pregnancy was assessed using a validated, self-administered diet history questionnaire. Dietary patterns from thirty-three predefined food groups (g/4184 kJ) were extracted by cluster analysis. The following three dietary patterns were identified: the 'meat and eggs' (n 326), 'wheat products', with a relatively high intake of bread, confectioneries and soft drinks (n 303), and 'rice, fish and vegetables' (n 174) patterns. After adjustment for potential confounders, women in the 'wheat products' pattern had infants with the significantly lowest birth weight (P = 0·045) and head circumference (P = 0·036) among those in the three dietary patterns. Compared with women in the 'rice, fish and vegetables' pattern, women in the 'wheat products' pattern had higher odds of having a SGA infant for weight (multivariate OR 5·2, 95 % CI 1·1, 24·4), but this was not the case for birth length or head circumference. These results suggest that a diet high in bread, confectioneries, and soft drinks and low in fish and vegetables during pregnancy might be associated with a small birth weight and an increased risk of having a SGA infant.

    Although several nutrients and foods are suggested to be preventive against postpartum depression, all previous studies have primarily focused on single nutrients or foods. In contrast, studies on dietary patterns, namely the measurement of overall diet by considering the cumulative effects of nutrient, may provide new insights into the influence of diet on postpartum depression. We prospectively examined the association between dietary patterns during pregnancy and the risk of postpartum depression among 865 Japanese women. Diet was assessed with a validated, self-administered diet history questionnaire. Dietary patterns from thirty-three predefined food groups (energy-adjusted food (g/d)) were extracted by factor analysis. Postpartum depression was defined as present when the subjects had an Edinburgh Postnatal Depression Scale score of ≥ 9 at 2-9 months postpartum. A total of 121 women (14·0 %) were classified as having postpartum depression. Three dietary patterns were identified: 'Healthy', 'Western' and 'Japanese' patterns. After adjustment for potential confounders, neither the 'Healthy' nor the 'Japanese' pattern was related to the risk of postpartum depression. Compared with the first quartile of the 'Western' pattern, only the second quartile was independently related to a decreased risk of postpartum depression (multivariate OR 0·52, 95 % CI 0·30, 0·93), although no evident exposure-response associations were observed (P for trend = 0·36). The present study failed to substantiate clear associations between dietary patterns and the risk of postpartum depression. Further studies with more accurate measurements are warranted to confirm the relationship between dietary patterns and the risk of postpartum depression.

    1995-12-31

    Free-electron laser (FEL) experiments have been conducted with the 38-MeV L-band electron linac at the Institute of Scientific and Industrial Research, Osaka University. It is a 1.3 GHz RF linac with a thermoionic gun, and equipped with two 12th and one 6th sub-harmonic prebunchers for producing the high-intensity single-bunch beam with a charge up to 67 nC/bunch. For oscillation experiments of FEL, the gun is replaced with that with a smaller cathode area in order to reduce the emittance of the beam. The normalized emittance has been measured to be 200 {pi} mm-mrad. The linac is operated in the long-pulse mode and one of the 12th sub-harmonic bunchers and the 6th sub-harmonic buncher are operated, so that the time duration of the macropulse is 4 {mu}s and the spacing between micropulses is 9.2 ns. The length of the micropulse is 30-40 ps and the charge in each micropulse is 2 nC. The electron beam from the linac is transported to a wiggler which has the period length of 6 cm and the number of periods of 32. The first half of the macropulse is lost in the transport line because the energy of electrons in that part gradually changes and there is a momentum slit in the transport line. An optical resonator is 5.53 m long and the round-trip time of light in it is 37 ns, which is precisely four times as long as the spacing of micropulses. Since the time duration of the macropulse passing through the wiggler is 1.8 {mu}s, the number of amplifications of light in the cavity is 49. The first lasing was achieved in 1994 at wavelengths between 32 and 40 {mu}m and preliminary results were reported at the l6th FEL Conference last year. The laser light was detected with a Ge:Be detector which has the time resolution of 3 {mu}s. Since the time duration of the macropulse of the laser fight is estimated to be less than 2 {mu}s, we could measure only the total energy in a macropulse of the output light.

    This study aimed to analyze and evaluate the association between tuberculosis (TB) and smoking in order to obtain basic information for the control of smoking. Of the 637 patients with sputum smear-positive pulmonary tuberculosis who were newly registered in Osaka City in 2009, 581 patients whose smoking status was identified were selected as study subjects. Data on the following were collected: patient characteristics, presence or absence of underlying conditions, patient's delay and doctor's delay in the diagnosis of TB, presence or absence of cavities, and degree of smear positivity. The patients were divided into the following three groups according to their smoking status: (1) never smokers (those who have never smoked), (2) former smokers (those who had smoked, but quitted), and (3) current smokers (those who smoke currently). (1) PATIENT CHARACTERISTICS: The subjects consisted of 413 males and 168 females, with mean ages of 65.7, 55.4, and 70.2 years for never smokers, current smokers, and former smokers, respectively. (2) Comparison with the national adult smoking rate (National health and nutrition survey 2009, Ministry of Health, Labour and Welfare): The prevalence of current smoking among male patients with sputum smear-positive pulmonary TB in Osaka was 62.4-82.4% among men in their 20s to 60s, and 27.5% among men in their 70s, which is higher than the national average. For female patients, the prevalence of current smoking was 46.2% among women in their 20s and 45.5% among women in their 30s, which is clearly higher than the national average. This was also true for those aged 40 years or older. (3) Severity of TB disease and smoking status: The presence of a cavity was significantly associated with being a male patient, being a current smoker, and longer patient's delay. Sputum smear grades (2+) and (3 +) were significantly correlated with being under 59 years old, being a current smoker, and longer patient's delay. The prevalence of current smokers

    Holocene relative sea-level changes in Hiroshima Bay were reconstructed from fossil ostracodes from a core, using a semi-quantitative method. In Hiroshima Bay, relative sea level rose rapidly (about 25 m) between ca. 9000 cal yr BP and ca. 5800 cal yr BP, after which it gradually fell (about 5 m) to its present level. The peak in relative sea level occurred at ca. 5800 cal yr BP. The sea-level curve for Hiroshima Bay is similar to curves for tectonically stable areas of Japan (e.g., Osaka Bay). ?? by the Palaeontological Society of Japan.

    As global threats such as climate change and economic crisis have been emerging, the demand for the establishment of integrated disciplinary education programs is increasing. The Research Institute for Sustainability Science (RISS) at Osaka University started a new program on sustainability in October 2007. The RISS program addresses the ways to utilize knowledge effectively to understand the dynamic interactions between nature and human society. This paper first overviews the RISS Program for Sustainability Science. The paper then discusses the main problems as well as attempts and efforts to challenge those issues. Although issues including institutional barriers and faculty development yet remain in promoting integrated education, the RISS program functions as a platform to disseminate the idea of sustainability science across the university.

    Influenza viruses in outpatients with influenza symptoms in Osaka City were analyzed in an epidemiological surveillance of infectious disease between 1989 and 1993. During influenza epidemics a mixed prevalence of several types of influenza viruses existed. Three types of influenza viruses, AH1, AH3 and B, were isolated during the 1990/1991 season. Remarkably the three types of viruses were discovered in samplings collected on the same day and within a narrow area inside a radius of 800-1,000m from the surveyed hospitals. Different types of viruses were detected between brothers and among school children from same housing complexes. Influenza AH3 viruses detected in 1992/1993 season differed in antigenicity from those detected in the 1990/1991 and 1991/1992 seasons. Therefore it appears that mutation of the AH3 virus contributed to the large-scale influenza epidemic which occurred in the 1992/1993 season.

    As one contribution to 'Global Heritage Stone Resources' (GHSR), some stone heritages in Japan, which are nominated in the interim list, are briefly introduced. The geology of Japanese Islands where are the one of the most active areas in the history of the Earth, is very complicated. Therefore Japanese Islands consist of various kinds of minerals and rocks. Some of them were used to make stone implements and accessories. Japanese people also used to the best possible advantage to built tombstone, gate, pavement ,and the basement and wall of the large building such as temples, shrines, castles and modern buildings. 1. Stone Heritages of Pre-historical age: In the late Pleistocene and the early Holocene, ancient Japanese used obsidian cooled rapidly from rhyolitic magma.to make small implements and accessories. For example, Shirataki, Hokkaido (north island) is the largest place producing obsidian in Japan where Paleolithic people made arrowhead, knives and so on. Another example, Jade yielded in Itoigawa City, Japan Sea coast of central Japan, was made in the metamorphic rock about five hundred million years ago. Itoigawa area is only one place where jade is abundantly produced in Japan. Ancient people had been already collected and processed to ornaments although it is very hard and traded in wide area more than several thousand years ago. 2. Stone Heritages of Historical age: 2.1 Archaeological remains: In the Kofun (old mound) period (250 to 538 AD), stone burial chambers were used for old mounds to preserve against the putrefaction and to protect from the theft. For example, Ishibutai Kofun ("ishi" means "stone" and "butai" means "stage") in Nara old capital city, southwest Japan, is the largest known megalithic structure made of granite in Japan. 2.2 Stone walls of some typical castles Stones used is because of not only the rich reserves of rocks but also restriction of transportation. Osaka (second biggest city) castle, are composed of Cretaceous granite

    Significant dioxin (polychlorinated dibenzo-para-dioxins (PCDDs)/polychlorinated dibenzo-furans (PCDFs)) pollution from a municipal solid waste incinerator was discovered in 1997 in Osaka prefecture/Japan. The cause and mechanism of pollution was identified by a detailed assessment of the environment and incinerator plant. The primary sources of PCDD/PCDF pollution were high dioxin releases from an intermittently operated waste incinerator with PCDD/PCDF emissions of 150 ng-TEQ/Nm(3). PCDD/PCDF also accumulated in the wet scrubber system (3,000 μg TEQ/L) by adsorption and water recirculation in the incinerator. Scrubber water was air-cooled with a cooling tower located on the roof of the incinerator. High concentrations of dioxins in the cooling water were released as aerosols into the surrounding and caused heavy soil pollution in the area near the plant. These emissions were considered as the major contamination pathway from the plant. Decontamination and soil remediation in and around the incinerator plant were conducted using a variety of destruction technologies (including incineration, photochemical degradation and GeoMelt technology). Although the soil remediation process was successfully finished in December 2006 about 3% of the waste still remains. The case demonstrates that releases from incinerators which do not use best available technology or which are not operated according to best environmental practices can contaminate their operators and surrounding land. This significant pollution had a large impact on the Japanese government's approach toward controlling dioxin pollution. Since this incident, a ministerial conference on dioxins has successfully strengthened control measures.

    Little is known about the improvement in out-of-hospital cardiac arrest (OHCA) survival among elderly patients. The aim of this study was to evaluate the trends in the survival after bystander-witnessed OHCA of cardiac origin in this age group. This prospective, population-based, observation of the whole population of Osaka, Japan included consecutive OHCA patients aged ≥65 years with emergency responder resuscitation attempts from January 1999 to December 2011. The primary outcome measure was one-month survival with neurologically favorable outcome, and the trends in the outcome from OHCA were evaluated by location. Multiple logistic regression analysis was used to assess factors that were potentially associated with neurologically favorable outcome. During the study period, a total of 10,876 bystander-witnessed OHCA of cardiac origin were eligible for our analyses. In whole arrests, the proportion of one-month survival with neurologically favorable outcome improved from 1.4% in 1999 to 4.8% in 2011 (P for trend <0.001). The proportion of neurologically favorable outcome in homes and public places improved from 0.7% in 1999 to 3.2% in 2011 (P for trend <0.001) and from 4.2% in 1999 to 20.9% in 2011 (P for trend <0.001), respectively, whereas, in nursing homes, the proportion of neurologically favorable outcome did not improve. In a multivariate analysis, bystander-initiated cardiopulmonary resuscitation and emergency response time were significant predictors for neurologically favorable outcome. In this population, survival from OHCA among elderly patients significantly improved during the study period, but the trends differed by the OHCA location. Copyright © 2014 Elsevier Ireland Ltd.

    The Project of Osaka-Institute-of-Technology Electric-Rocket-Engine onboard Small Space Ship (PROITERES) was started at Osaka Institute of Technology. In PROITERES, a 10-kg small satellite with electrothermal pulsed plasma thrusters (PPTs), named JOSHO, will be launched in 2010. The main mission is powered flight of small satellite by electric thruster itself. Electrothermal PPTs were studied with both experiments and numerical simulations. An electrothermal PPT with a side-fed propellant feeding mechanism achieved a total impulse of 3.6 Ns with a repetitive 10000-shot operation. An unsteady numerical simulation showed the existence of considerable amount of ablation delaying to the discharge. However, it was also shown that this phenomenon should not be regarded as the 'late time ablation' for electrothermal PPTs.

    1) Changes in the incidence rate of tuberculosis in Osaka City and Nishinari Ward. The incidence rate of tuberculosis among people living in Osaka City (per 100,000 people) was 41.5 (number of patients: 1,109) in 2011--an approximately 50% decrease from 82.6 in 2001. However, the figure is 2.3 times higher than the national incidence rate of tuberculosis (17.7), and the highest of all ordinance-designated cities and prefectures. Osaka City consists of 24 wards, and the incidence rate of tuberculosis varies from ward to ward. Although the incidence rate of tuberculosis in Nishinari Ward in 2011 was 199.6 (number of patients: 242) and the highest by far in the city, the figure is approximately 50% of the incidence rate in 2001 (405.9). There were two other wards with the incidence rate of 50.0 or higher, and the lowest incidence rate was 22.4. The incidence rate of tuberculosis in the Airin area of Nishinari Ward is particularly high. Although the number of newly registered patients decreased from 336 to 128 over the past ten years, and the incidence rate significantly decreased from 1,120.0 to 426.7 (when the population of the area was estimated to be 30,000), it is still 24.1 times higher than the national incidence rate. 2) Basic guidelines for tuberculosis strategy developed by Osaka City. Osaka City has developed basic guidelines for tuberculosis strategy to address patients with tuberculosis and eradicate the disease. The first and second periods of the basic guidelines for tuberculosis strategy were ten years from 2001 and 2011, respectively. The overall objective of these basic guidelines was to significantly reduce the incidence rate of tuberculosis, and numerical targets related to basic policies and specific activities were set to accomplish the goal. The basic guidelines allow Osaka City, including its public health centers, to implement measures against tuberculosis as a municipal project. 3) Assessment of the City's efforts. The measures were assessed

    In Japan, R and D activities on laser materials processing are mainly conducted in universities, public research institutions, and technical centers in private enterprise. Among them the Welding Research institute and the Department of Welding and Production Engineering, both at Osaka University, have taken the initiative in conducting fundamental studies on laser materials processing as well as training experts and engineers in laser technology since the mid 1960s. In 1990, a new laser center called the Applied Laser Engineering Center (ALEC) was established in Nagaoka City in Niigata Prefecture by the investments of New Energy and Industrial Technology Development Organization (NEDO), Niigata Prefecture, City of Nagaoka, and many private companies in order to develop industrial applications of laser technologies. The Center has a wide variety of lasers covering wavelengths from infrared to ultraviolet, and many research projects are carried out under the sponsorship of the government, self-governing bodies, and private companies. Another new laser center, the Advanced Materials Processing Institute (AMPI), was recently established in Amagasaki City, a neighboring city to Osaka, under the sponsorship of the City of Amagasaki and many private enterprises, where a 50 kW CO{sub 2} laser and a 5 kW YAG laser (fiber combining two 2 kW CW lasers and a 1 kW pulsed laser) were installed in November 1994. Major targets of the R and D are the development of laser welding and cutting of thicker materials, laser surface modification, and hybrid plasma-laser thermal spraying.

    This study aimed to clarify stages of condom use among gay and bisexual men at gay bars in Osaka and to assess relationships between condom use stage and attitudes and norms regarding HIV prevention. In this cross-sectional study, a self-administered survey was distributed to gay bar customers in Osaka in 2005. Completed surveys were received through the mail. Participants were divided into five groups based on condom use with regular and casual partners: pre-contemplation; contemplation; preparation; action; and maintenance. These five groups were merged into three groups: precontemplation; contemplation/preparation; and action/maintenance. Associations between these three groups of condom use stage and correlates were assessed. Among the 601 respondents (response rate, 44.9%), data from 546 men with lifetime sexual experience with men were used. Regarding stage distribution, the highest percentage of participants was in the pre-contemplation stage with a regular partner, and in the maintenance stage with casual partners. Activities of "MASH Osaka", a gay non-governmental organization, were widely recognized across all stages. The feeling of being unable to tell a partner to use a condom if the partner resisted condom use, being in a long-term relationship, difficulty using condoms when under the influence of drugs or alcohol, and self-efficacy all correlated with condom use stages. This study clarified condom use stages and correlations among gay and bisexual men at gay bars in Osaka. More research is needed to assess the reliability and validity of these scale items. Monitoring stage distributions and correlations with stages will be useful to evaluate HIV prevention activities.

    To clarify the actual condition of endoscope sterilization work and the adverse health effects of disinfectants on personnel, a questionnaire was sent to 173 medical institutions in Osaka Prefecture. Glutaraldehyde (GA), ortho-phtalaldehyde (OPA), and hyperacetic acid were used as disinfectants of endoscopes by 55.5%, 32.4%, and 8.7% of the medical institutions respectively. The kind of disinfectant used had been changed in 57.8% of these institutions during the past five years, and it was confirmed that the use of substitutes for GA, such as OPA and hyperacetic acid, has increased. Personnel in 35.8% of the institutions complained about symptoms during sterilization work. The kind of disinfectant being used when they complained was GA in many cases and OPA in others. A general ventilation system has now been installed in 72.3% of the institutions; local exhaust systems have been installed in fewer, only 23.4%. Protective gloves were used at about half of the institutions, but protective masks and glasses were seldom used. This study shows that the occupational health problems of endoscope sterilization work have not been resolved. Consequently, it is necessary to promote the installation of ventilation systems and the use of protective devices in all institutions. Health education in regard to the handling of disinfectants is also necessary. Because little information is available about the toxic effects of OPA and hyperacetic acid, epidemiological studies must be conducted to clarify the human health effect of these disinfectants.

    A new research project on extreme ultraviolet (EUV) source development has just been started at the Institute of Laser Engineering, Osaka University. The main task of this project is to find a scientific basis for generating efficient, high-quality, high power EUV plasma source for semiconductor industry. A set of experimental data is to be provided to develop a detailed atomic model included in computer code through experiments using GEKKO-XII high power laser and smaller but high-repetitive lasers. Optimum conditions for efficient EUV generation will be investigated by changing properties of lasers and targets. As the first step of the experiments, spherical solid tin and tin-oxide targets were illuminated uniformly with twelve beams from the GEKKO XII. It has been confirmed that maximum conversion efficiency into 13.5 nm EUV light is achieved at illumination intensity less than 2 x 1011 W/cm2. No significant difference is found between laser wavelengths of one μm and a half μm. Density structure of the laser-irradiated surface of a planar tin target has beem measured experimentally at 1012 W/cm2 to show formation of double ablation structure with density plateau by thermal radiation transport. An opacity experiment has just been initiated.

    Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have recently received attention owing to their widespread contamination in the environment. One of major manufacturers, 3M Company voluntarily phased out PFOS production in 2002. We measured the PFOS and PFOA concentrations in serum samples from Japan (Sendai, Takayama and Osaka), Korea (Busan and Seoul) and Vietnam (Hanoi) to evaluate the possible effects of the phase-out on the serum levels. There were spatial differences in both the serum PFOS and PFOA concentrations. The serum PFOS concentrations (ngmL(-1)) evaluated as the geometric mean (geometric standard deviation) in 2007-2008 ranged from 4.86 (1.45) in Sendai, Japan, to 9.36 (1.42) in Busan, Korea. The serum PFOA concentrations ranged from 0.575 (2.32) in Hanoi, Vietnam, to 14.2 (1.73) in Osaka, Japan. Historically archived samples collected from Korea in 1994-2008 revealed that the serum PFOA concentrations increased by 1.24-fold in Busan from 2000 to 2008 and 1.41-fold in Seoul from 1994 to 2007. On the other hand, the serum PFOS concentrations did not change from 1994 to 2007/2008. The serum PFOS levels in Japan in 2008 were significantly decreased compared with previously reported values (22.3-66.7% of the values in 2003/2004). However, the serum PFOA levels showed a clear decline from 2003 to 2008 in a high-exposed area, Osaka, but not in low-exposed areas in Japan. The trends toward decreases were not uniformly observed in Asian countries, unlike the case for the United States, suggesting that local factors associated with the production and introduction histories in each country overwhelm the effects of the phase-out. 2010 Elsevier Ltd.

    Factors influencing clinical course of brace treatment apply to adolescent idiopathic scoliosis (AIS) patients remain unclear. By making clear them, we may select suitable patients for brace treatment and alleviate overtreatment. The purpose of this study was to explore predictive factors of Osaka Medical College (OMC) brace treatment for AIS patients in accordance with the modified standardized criteria proposed by the Scoliosis Research Society (SRS) committee on bracing and non-operative management. From 1999 through 2010, 31 consecutive patients with AIS who were newly prescribed the OMC brace and met the modified SRS criteria were studied. The study included 2 boys and 29 girls with a mean age of 12 years and 0 month. We investigated the clinical course and evaluated the impacts of compliance, initial brace correction rate, curve flexibility, curve pattern, Cobb angle, chronological age, and Risser stage to clinical outcomes. The clinical course of the brace treatment was considered progression if ≥6° curvature increase occurred and improvement if ≥6° curvature decrease occurred according to SRS judgment criteria. The curve progressed in 10 cases, the curve improved in 6 cases, and the curve remained unchanged in 15 cases (success rate: 67.7%). The success rate was statistically higher in the patient group whose instruction adherence rate was greater than 50% as compared with in those 50% or less. Initial brace correction rate, curve flexibility, curve pattern, the magnitude of Cobb angle, chronological age, and Risser stage did not have any significant effect for clinical courses. However, success rate was insignificantly higher in the cases whose Cobb angle in brace was smaller than that in hanging position. OMC brace treatment could alter the natural history of AIS, however, that was significantly affected by compliance of brace wear.

    PM2.5 has become one of the most important aspects in recent air pollution issues. In Japan, the achievement rate of the environmental quality standard for PM2.5 is in a worse situation so far (43.3% for ambient air monitoring station, 33.3% for roadside air pollution monitoring station in FY2012). Therefore, source apportionment will be essential to policy and decision making for improving the PM2.5 pollution. Since 2011, we started the field monitoring study called "Current Status Elucidation and Source Contribution Assessment of PM2.5 Pollution in Collaboration with Environmental Research Institutes across Japan" which was granted by the Environment Research and Technology Development Fund (5B-1101) of the Ministry of the Environment, Japan. PM2.5 samples were collected at 14 sites during four campaigns. Chemical analyses of carbonaceous compounds, ionic species, and elements were conducted. Source apportionment was performed by using Positive Matrix Factorization (PMF, EPA PMF 3.0) and Chemical Mass Balance (CMB, EPA CMB 8.1) models. PMF model resolved a six-factor solution. Each of these factors has a distinctive grouping of species that can be associated with a specific source sector (F1: Biomass burning, F2: Sulfate + Oil combustion, F3: Industry, F4: Nitrate, F5: Sulfate + Coal combustion, and F6: Chloride). In the winter campaign (Jan. 24 to Feb. 7) in 2013, F5 accounted for 50% of total PM2.5 mass at Tsushima (34.2°N 129.3°E, the westernmost remote site). The contribution of F5 tended to decrease toward the eastern sites (27% at Fukuoka (33.5°N 130.5°E, urban site), 22% at Higashi-Osaka (34.7°N 135.6°E, urban site)). CMB model showed similar results in the same campaign. Coal combustion accounted for 49%, 30%, and 22% of total PM2.5 mass at Tsushima, Fukuoka, and Higashi-Osaka, respectively (Fig.1). On the other hand, at urban sites, higher contributions from local sources such as secondary nitrate (16% at Fukuoka, 21% at Higashi-Osaka), diesel fuel

    In Japan, the first actual survey of morbidity from cancer was conducted by Dr. Mitsuo Segi in Miyagi Prefecture from 1951 to 1953. Population-based cancer registries were started in 1957 in Hiroshima and 1958 in Nagasaki for the follow-up of survivors of the atomic bombings. Public population-based cancer registries, under the cancer control programs of the prefectural governments, were started in Aichi and Osaka prefectures in 1962. After the Law on Health and Medical Services for the Aged was enacted in 1983, population-based cancer registries were initiated promptly in many prefectures. As of 2007, there were population-based cancer registries in 35 of Japan's 47 prefectures and in one city. The Research Group for Population-Based Cancer Registration in Japan was organized by Dr. Isaburo Fujimoto, the chairperson in 1975, with a grant-in-aid from the National Cancer Research Promotion Program. This research group has continued until now and has been making continuous efforts. To promote standardization of the registry process and to improve the quality of registry data, the Japanese Association of Cancer Registries (JACR) was organized in 1992. The Japanese government Third-Term 10-Year Comprehensive Strategy for Cancer Control was launched in 2004, with the slogan "Targeting a drastic reduction in cancer morbidity and mortality." This strategy includes not only promoting cancer research but also promoting cancer prevention, improving the quality of cancer care, promoting social support systems, and promoting effective systems for monitoring cancer incidence and survival.

    The Irago Conference 2012 - 360 degree outlook on critical scientific and technological challenges for a sustainable society Organized by the Electronics-Inspired Interdisciplinary Research Institute (EIIRIS) at Toyohashi University of Technology, the Irago Conference, held recently (15-16 November) in Aichi, Japan, aimed to enhance mutual understanding between scientists, engineers and policymakers. Over 180 participants tackled topics ranging from energy and natural resources to public health and disaster prevention. The 360-degree outlook of the conference impressed speakers and guests. ''This conference has been extremely informative,'' noted Robert Gellar from the University of Tokyo. ''A unique conference with experts from a range of backgrounds,'' agreed Uracha Ruktanonchai from the National Nanotechnology Center (NANOTEC) in Thailand. Similarly, G P Li, professor of electrical engineering and computer science at the University of California Irvine commented that he had been ''able to think the unthinkable'' as a range of topics came together. The conference was streamed live on Ustream to ensure that researchers from across the world could benefit from thought-provoking presentations examining global issues such as energy, disaster mitigation and nanotechnology. ''This was wonderful,'' said Oussama Khatib from Stanford University, ''A good recipe of speakers from such a range of backgrounds.'' Manuscripts submitted to the organizers were peer-reviewed, and the papers in this proceedings were accepted for Journal of Physics: Conference Series. In addition to the formal speaker programme, graduate-student sessions provided a platform for graduate students to describe their latest findings as oral presentations. A series of excursions to relevant locations, such as the Tahara megasolar region under construction and a local car-manufacturing factory, gave participants the opportunity to further consider practical applications of their research in industry

    2005-03-01

    With the ongoing miniaturization of devices and controlled nanostructuring of materials, the importance of atomic-scale information on surfaces and surface properties is growing continuously. The astonishing progress in nanoscience and nanotechnology that took place during the last two decades was in many ways related to recent progress in high-resolution imaging techniques such as scanning tunnelling microscopy and transmission electron microscopy. Since the mid-1990s, non-contact atomic force microscopy (NC-AFM) performed in ultrahigh vacuum has evolved as an alternative technique that achieves atomic resolution, but without the restriction to conducting surfaces of the previously established techniques. Advances of the rapidly developing field of NC-AFM are discussed at annual conferences as part of a series that started in 1998 in Osaka, Japan. This special issue of Nanotechnology is a compilation of original work presented at the 7th International Conference on Non-contact Atomic Force Microscopy that took place in Seattle, USA, 12-15 September 2004. Over the years, the conference grew in size and scope. Atomic resolution imaging of oxides and semiconductors remains an issue. Noticeable new developments have been presented in this regard such as, e.g., the demonstrated ability to manipulate individual atoms. Additionally, the investigation of individual molecules, clusters, and organic materials gains more and more attention. In this context, considerable effort is undertaken to transfer the NC-AFM principle based on frequency modulation to applications in air and liquids with the goal of enabling high-resolution surface studies of biological material in native environments, as well as to reduce the experimental complexity, which so far involves the availability of (costly) vacuum systems. Force spectroscopy methods continue to be improved and are applied to topics such as the imaging of the three-dimensional force field as a function of the distance with

  13. Complicated feature of atmospheric aerosols shown in the yellow sand events in Japan

    NASA Astrophysics Data System (ADS)

    Mukai, Sonoyo; Sano, Itaru; Mukai, Makiko

    It is well known that aerosol has a significant potential to the earth's climate. The aerosol distributions in Asia are very complex due to the increasing emissions of small anthropogenic particles associated with economic growth and large dust particles called yellow sands transported on the westerly wind from the continental desert areas. In this study, aerosol properties in the yellow sand events are focused and analyzed from comprehensive aspects. Yellow sand events have often happened in spring. Therefore they have been called 'spring haze' involving an expectation of coming spring to Japan. However the recent yellow sand events are too heavy and too severe to call 'spring haze' due to the increasing of desert areas and contamination with the anthropogenic emissions. The sun/sky photometry has been undertaken at NASA/AERONET stations in Osaka, Shirahama and Noto in Japan. Suspended particulate matter (PM) and OBC (Optical Black Carbon) have been simultaneously measured there. The simultaneous monitoring of aerosols and PM provides such a relation between them as there is a linear correlation between PM concentrations and AOT, which indicates that AOT can be estimated from PM data, and vice versa. It is found that the value of aerosol optical thickness (AOT) during aerosol event is more than double its usual value, and fine anthropogenic particles dominate even during dust events in Japan. It is of interest to mention that yellow sand events in Japan seem to be caused by a mixture of non-absorbing coarse dust and other small haze particles, especially shown in the event in May 2007. A new instrument of NIES/LIDAR network to be set at AERONET/Osaka station in March 2008 is expected to provide us with the vertical distribution of yellow sand particles. Furthermore the model simulations with SPRINTARS/AGCM/CCSR/NIES/FRCGC and satellite data will be available for our better understanding of the beyond pollution of the atmosphere.

    As the number of donated organs is still extremely small in Japan compared with other developed countries, in-hospital procurement transplant coordinators (In-Hp PTC) may play an important role in increasing organ donation and making the procurement procedure smoother. In this study, our education program of In-Hp PTC is described. In May 2012, our department started the In-Hp PTC Education Program. In the first semester, a 2-hour lecture is provided every 2 weeks for 5 months to 15 In-Hp PTCs working near Osaka. In the second semester, 20 lectures were provided for 3 consecutive days to 31 In Hp PTCs, more than 80% of whom work far from Osaka. Lecture topics were the history and current status of organ donation in Japan, social regulation of organ donation, care of transplant recipients, overall procedures of organ donation, the role of In-Hp PTC, donor family care, donor indications, and donor assessment and management. Lectures also included simulations of the organ donation process. Participants were surveyed for their opinions after the program, Most participants were satisfied with the program, topics and duration. As most of them are not full-time In-Hp PTCs, they preferred to attend the 3-day program. Many participants are currently working as main In-Hp PTCs and establishing their own organ donation system in their hospital. In-Hp PTCs have an important role to play in establishing an organ procurement system and increasing organ donation in Japan. This program may help establish a systematic education program for this occupation in Japan. Copyright © 2014 Elsevier Inc. All rights reserved.

    Global warming is increasingly recognized as a threat to the survival of human beings, because it could cause a serious increase in the occurrence of diseases due to environmental heat during intermittent hot weather. To assess the direct impact of extremely hot weather on human health, we investigated heat-related deaths in Japan from 1968 through 1994, analyzing the data to determine the distribution of the deaths by age and their correlation to the incidence of hot days in summer. Vital Statistics of Japan, published by the Ministry of Health and Welfare of Japan, was the source of the heat-related mortality data employed in this study. Meteorological data were obtained from the District Meteorological Observatories in Tokyo and Osaka, the two largest cities in Japan. Heat-related deaths were most prone to occur on days with a peak daily temperature above 38°C, and the incidence of these deaths showed an exponential dependence on the number of hot days. Thus, even a small rise in atmospheric temperature may lead to a considerable increase in heat-related mortality, indicating the importance of combating global warming. Furthermore, half (50.1%) of the above-noted deaths occurred in children (4 years and under) and the elderly (70 years and over) irrespective of gender, indicating the vulnerability of these specific age groups to heat. Since a warmer climate is predicted in the future, the incidence of heat waves will increase, and more comprehensive measures, both medical and social, should be adopted for children of 4 years and younger the elderly to prevent heat-related deaths in these age groups.

    The number of students with food allergy is currently increasing. Moreover, the unintentional mixing or accidental ingestion of allergy-causing food materials in school lunches has attracted great attention. The aim of this study was to verify the current status of elementary school lunch provision for students with food allergy. We investigated the elementary school lunch services in seven cities in Osaka prefecture. The egg elimination diet was provided in five of the seven cities. In four of these five cities, we did not detect the presence of egg residue either on the surface of various cookware used to prepare the egg elimination diet or in the food itself. In this investigation, the egg elimination diet was provided properly, but we observed differences among the cities in the manual preparation of foods for food allergy diets. To step up these efforts, our results suggest the necessity of preparing a manual to consider individual conditions of school lunch services.

    Blue cotton is a cotton preparation, bearing copper phthalocyanine trisulfonate as a covalently linked ligand, and is an adsorbent specific for compounds with three or greater number of fused rings. Due to this special property, blue cotton has been used for extracting mutagenic polycyclic compounds from crude materials. In early work, the authors gave a brief account of the results of monitoring river-water mutagenicity with blue cotton. Recently they have improved the quality of the adsorbent; rayon in place of cotton was employed as the support for the ligand, and a more powerful adsorbent, blue rayon, which contains 2-3 times greater amount of the ligand than blue cotton, was prepared. In this paper the authors report the use of the blue-rayon method to detect mutagenic compounds in the Yodo river, which flows through the cities of Kyoto and Osaka and is a major source of drinking water for the 10 million people in the area.

    Fujita, Kikuo

    Department of Mechanical Engineering, Graduate School of Engineering, Osaka University is now developing “Graduate Education Program of Design and Integration Capability” under the MEXT's scheme entitled “Initiatives for Attractive Education in Graduate Schools”. Maturation of society and life, globalization of manufacturing industry, latest demands of human's welfare have changed the meaning of design from functional ensureance to value creation. This requests graduate education of mechanical engineering to turn its definition over both synthesis and analysis and to learning and communication capabilities beyond knowledge itself. With recognizing such a background, the program aims to reform the education curriculum of mechanical engineering by introducing a product design subject which integrates design methodology education and project-based learning over industry- sponsored design problems, several graduate-level fundamental subjects, and the depth area system in which elective subjects are categorized into several areas based on their specialty. This paper describes the objectives, undertakings, promises, etc. of the program.

    Population-based cancer registries are operated by over 80% of prefectures in Japan. However, only a limited proportion of the registries can provide long-term incidence data. Here, we aimed to establish a method for monitoring cancer incidence trends in Japan using data from selected prefectures. Based on the availability of long-term (≥ 20 years) high-quality data, we collected incidence data from five prefectures (Miyagi, Yamagata, Fukui, Osaka, and Nagasaki), which included an annual average of 54,539 primary cancer cases diagnosed between 1985 and 2004. Cancer mortality data for 1995-2004 were obtained from the vital statistics. Representativeness and homogeneity of the trends were examined by funnel plot analysis of log-linear regression coefficients calculated for the most recent 10 years of data (1995-2004) of age-standardized rates (ASR). The ASR of incidence for five prefectures in total (5-pref total) showed a significant decrease, with an annual percent change (APC) of -1.0 (95% confidence interval [CI] -1.4: -0.6) for males and -0.4 (95% CI -0.8: -0.1) for females. Excluding data from Osaka (4-pref total) reversed the decreasing trend; the corresponding APC was +0.4 (95% CI -0.2: +1.0) for males and +0.7 (95% CI +0.5: +0.9) for females. The APCs for the ASR of mortality for the 4-pref total (males, -1.5; females, -1.3) were more representative of nationwide data (males, -1.4 [95% CI -1.7: -1.2]; females, -1.1 [95% CI -1.4: -0.9]) than those for the 5-pref total (males, -1.7; females, -1.4). We conclude that using data from Miyagi, Yamagata, Fukui, and Nagasaki prefectures, with continuous monitoring of the representativeness of the data, is a provisionally relevant way to evaluate cancer incidence trends in Japan.

    The principal meeting attended during this trip was the Japan International Tribology Conference Nagoya 1990. The conference encompassed a wide range of topics, including the tribology of ceramics, the tribology in high-performance automobiles, and many aspects of lubrication technology. Associated forums were also held on the tribology of advanced ceramics, on solid lubrication, and on automotive lubricants. Presentations made during the latter forum discussed anticipated trends in engine development and anticipated improvements in lubricants required for the next generation of engines. In addition to meetings, site visits were made to five industrial organizations to discuss ceramic tribology. Nippon Steel Corporation and Toshiba Corporation are both very active in the ceramic area, Nippon Steel from their interest in research on new materials and Toshiba from both an interest in new materials and in support of their work in electronic devices. Two engine manufacturers were also visited, Toyota Motor Corporation, and Nissan Motor Co., Ltd. These companies were somewhat reserved in their discussion of progress in the utilization of ceramics in automobile engines.

    Reichling, Michael

    2004-02-01

    Direct nanoscale and atomic resolution imaging is a key issue in nanoscience and nanotechnology. The invention of the dynamic force microscope in the early 1990s was an important step forward in this direction as this instrument provides a universal tool for measuring the topography and many other physical and chemical properties of surfaces at the nanoscale. Operation in the so-called non-contact mode now allows direct atomic resolution imaging of electrically insulating surfaces and nanostructures which has been an unsolved problem during the first decade of nanotechnology. Today, we face a most rapid development of the technique and an extension of its capabilities far beyond imaging; atomically resolved force spectroscopy provides information about local binding properties and researchers now develop sophisticated schemes of force controlled atomic manipulation with the tip of the force microscope. Progress in the field of non-contact force microscopy is discussed at the annually held NC-AFM conferences that are part of a series started in 1998 with a meeting in Osaka, Japan. The 6th International Conference on Non-contact Atomic Force Microscopy took place in Dingle, Ireland, from 31 August to 3 September 2003 and this special issue is a compilation of the original publications of work presented at this meeting. The papers published here well reflect recent achievements, current trends and some of the challenging new directions in non-contact force microscopy that have been discussed during the most stimulating conference days in Dingle. Fundamental aspects of forces and dissipation relevant in imaging and spectroscopy have been covered by experimental and theoretical contributions yielding a more detailed understanding of tip--surface interaction in force microscopy. Novel and improved imaging and spectroscopy techniques have been introduced that either improve the performance of force microscopy or pave the way towards new functionalities and applications

    The coin-operated-locker baby is a type of child abuse that may be unique to Japan. The term refers to newborns who are placed, while alive or dead, in coin-operated lockers. This practice has been decreased by specific measures. It is likely that social and economic variables in Japan account for differences in the frequency and types of child abuse cases when compared to American or European societies as social conditions in Japan change the reported incidence of child abuse may increase in the future. Recently, the government of Osaka organized a group specifically designed to deal with the detection and protection of abused and neglected children. In 1993, they published a manual on how to deal with child abuse, but the Japanese judicial administration still uses old laws for abuse cases. The development of new laws is occurring in parts of the country now. This paper introduces the present status of coping with child abuse and neglect in Japan.

    In preparation for a collaborative multidisciplinary study of the pathogenesis of esophageal cancer, the authors reviewed the published literature to identify similarities and differences between Japan and China in esophageal cancer epidemiology. Esophageal squamous cell carcinoma (ESCC) is the predominant histologic type, while the incidence of esophageal adenocarcinoma remains extremely low in both countries. Numerous epidemiologic studies in both countries show that alcohol consumption and cigarette smoking are contributing risk factors for ESCC. There are differences, however, in many aspects of esophageal cancer between Japan and China, including cancer burden, patterns of incidence and mortality, sex ratio of mortality, risk factor profiles, and genetic variants. Overall incidence and mortality rates are higher in China than in Japan, and variation in mortality and incidence patterns is greater in China than in Japan. During the study period (1987–2000), the decline in age-adjusted mortality rates was more apparent in China than in Japan. Risk factor profiles differed between high- and low-incidence areas within China, but not in Japan. The association of smoking and drinking with ESCC risk appears to be weaker in China than in Japan. Genome-wide association studies in China showed that variants in several chromosome regions conferred increased risk, but only genetic variants in alcohol-metabolizing genes were significantly associated with ESCC risk in Japan. A well-designed multidisciplinary epidemiologic study is needed to examine the role of diet and eating habits in ESCC risk. PMID:23629646

    We aimed to analyse late toxicity associated with external beam radiation therapy (EBRT) for prostate cancer using uniform dose-fractionation and beam arrangement, with the focus on the effect of 3D (CT) simulation and portal field size. We collected data concerning patients with localized prostate adenocarcinoma who had been treated with EBRT at five institutions in Osaka, Japan, between 1998 and 2006. All had been treated with 70 Gy in 35 fractions, using the classical 4-field technique with gantry angles of 0°, 90°, 180° and 270°. Late toxicity was evaluated strictly in terms of the Common Terminology Criteria for Adverse Events Version 4.0. In total, 362 patients were analysed, with a median follow-up of 4.5 years (range 1.0–11.6). The 5-year overall and cause-specific survival rates were 93% and 96%, respectively. The mean ± SD portal field size in the right–left, superior–inferior, and anterior–posterior directions was, respectively, 10.8 ± 1.1, 10.2 ± 1.0 and 8.8 ± 0.9 cm for 2D simulation, and 8.4 ± 1.2, 8.2 ± 1.0 and 7.7 ± 1.0 cm for 3D simulation (P < 0.001). No Grade 4 or 5 late toxicity was observed. The actuarial 5-year Grade 2–3 genitourinary and gastrointestinal (GI) late toxicity rates were 6% and 14%, respectively, while the corresponding late rectal bleeding rate was 23% for 2D simulation and 7% for 3D simulation (P < 0.001). With a uniform setting of classical 4-field 70 Gy/35 fractions, the use of CT simulation and the resultant reduction in portal field size were significantly associated with reduced late GI toxicity, especially with less rectal bleeding.

    Active travel can contribute to physical activity achieved over a day. Previous studies have examined active travel associated with trips in various western countries, but few studies have examined this question for the Asian context. Japan has high levels of cycling, walking and public transport, similar to The Netherlands. Most studies have focused either on children or on adults separately, however, having children in a household will change the travel needs and wants of that household. Thus, here a household lifecycle stage approach is applied. Further, unlike many previous studies, the active travel related to public transport is included. Lastly, further to examining whether the built environment has an influence on the accumulation of active travel minutes, a binary logistic regression examines the built environment's influence on the World Health Organization's recommendations of physical activity. The findings suggest that there is a clear distinction between the urbanized centers and the surrounding towns and unurbanized areas. Further, active travel related to public transport trips is larger than pure walking trips. Females and children are more likely to achieve the WHO recommendations. Finally, car ownership is a strong negative influence.

    Pathogenic amyloid-β peptide precursor (APP) mutations clustered around position 693 of APP-position 22 of the Aβ sequence--are commonly associated with congophilic amyloid angiopathy (CAA) and intracerebral hemorrhages. In contrast, the Osaka (E693Δ) intra-Aβ APP mutation shows a recessive pattern of inheritance that leads to AD-like dementia despite low brain amyloid on in vivo positron emission tomography imaging. Here, we investigated the effects of the Osaka APP mutation on Aβ accumulation and deposition in vivo using a newly generated APP transgenic mouse model (E22ΔAβ) expressing the Osaka mutation together with the Swedish (K670N/M671L) double mutation. E22ΔAβ mice exhibited reduced α-processing of APP and early accumulation of intraneuronal fibrillar Aβ oligomers associated with cognitive deficits. In line with our in vitro findings that recombinant E22Δ-mutated Aβ peptides form amyloid fibrils, aged E22ΔAβ mice showed extracellular CAA deposits in leptomeningeal cerebellar and cortical vessels. In vitro results from thioflavin T aggregation assays with recombinant Aβ peptides revealed a yet unknown antiamyloidogenic property of the E693Δ mutation in the heterozygous state and an inhibitory effect of E22Δ Aβ42 on E22Δ Aβ40 fibrillogenesis. Moreover, E22Δ Aβ42 showed a unique aggregation kinetics lacking exponential fibril growth and poor seeding effects on wild-type Aβ aggregation. These results provide a possible explanation for the recessive trait of inheritance of the Osaka APP mutation and the apparent lack of amyloid deposition in E693Δ mutation carriers.

    The aim of this study was to evaluate our clinical experience with the Jarvik 2000 axial flow pump (Jarvik Heart, Inc, New York, NY, USA), a miniature axial flow left ventricular assist device (LVAD). The clinical results of eight patients, who underwent LVAD implantation with the Jarvik 2000 (median age 55.0 years; six men) between 2005 and 2010, including two who participated in a multicenter clinical trial in Japan, were reviewed. Two patients underwent LVAD implantation as destination therapy. Four patients underwent Jarvik 2000 implantation via median sternotomy, while the other four underwent implantation via left thoracotomy. There were no major complications during surgery. Four patients were supported for more than 2 years. The longest support duration was 1,618 days. Six patients successfully bridged to heart transplantation after a median 725 days of support. One patient on destination therapy died of a cerebral infarction. The other patient on destination therapy had had the LVAD for 1,618 days. The overall survival rates at 1, 2, and 3 years were 100, 86, and 86%, respectively. The median postoperative serum lactate dehydrogenase level was 860.5 U/L at 1 month, 735 U/L at 6 months, and 692 U/L at 1 year. There were no fatal device-related infections. We found that the Jarvik 2000 with pin bearing could support patients with end-stage heart failure with acceptable mortality and morbidity rates. Further evaluations of the prevalence of thromboembolic and hemolytic events in patients with the new conical-bearing Jarvik 2000 are required.

    Epidemiological studies associated with breastfeeding have provided conflicting results about whether it is preventive or a risk factor for atopic eczema in children. The current prospective study investigated the relationship between breastfeeding and the risk of atopic eczema in Japan. A birth cohort of 763 infants was followed. The first survey during pregnancy and the second survey between 2 and 9 months postpartum collected information on potential confounding factors and atopic eczema status. Data on breastfeeding and symptoms of atopic eczema were obtained from questionnaires in the third survey from 16 to 24 months postpartum. The following variables were a priori selected as potential confounders: maternal age, maternal and paternal history of asthma, atopic eczema, and allergic rhinitis, indoor domestic pets (cats, dogs, birds, or hamsters), family income, maternal and paternal education, maternal smoking during pregnancy, baby's sex, baby's birth weight, baby's older siblings, household smoking in the same room as the infant, and time of delivery before the third survey. In the third survey, 142 infants (18.6%) were revealed to have developed atopic eczema based on criteria of the International Study of Asthma and Allergies in Childhood. In an overall analysis, neither exclusive nor partial breastfeeding was significantly related to the risk of atopic eczema. After excluding 64 infants identified with suspected atopic eczema in the second survey, both exclusive breastfeeding for 4 months or more and partial breastfeeding for 6 months or more were independently associated with an increased risk of atopic eczema only among infants with no parental history of allergic disorders [multivariate odds ratios were 2.41 (95% confidence interval, 1.10-5.55) and 3.39 (95% confidence interval, 1.20-12.36), respectively]. The authors found that, overall, neither exclusive nor partial breastfeeding had a strong impact on the risk of atopic eczema. However, a parental

    Way back in the mid-1990s, as a young PhD student, I wrote a Lateral Thoughts article about my first experience of an academic conference (Physics World 1994 October p80). It was a peach of a trip - most of the lab decamped to Grenoble for a week of great weather, beautiful scenery and, of course, the physics. A whole new community was there for me to see in action, and the internationality of it all helped us to forget about England's non-appearance in the 1994 World Cup finals.

    ERTS-1 took very valuable MSS imageries of Osaka Bay and its vicinity on October 24, 1972. In the MSS-4 and MSS-5 imageries a complex grey pattern of water masses can be seen. Though some of grey colored patterns seen in black and white prints of the MSS-4 and MSS-5 imageries are easily identified from their shapes as cloud covers or polluted water masses characterized by their color tone in longer wavelengths in the visible region, any correct distribution pattern of polluted or turbid water masses can be hardly detected separately from thin cloud covers in a quick look analysis. In the present investigation, a simple photographic technique was applied using the fact that reflected sun light from cloud including smog and inclined water surfaces of wave have a certain component in the near infrared region, that MSS-7, whereas the light scattered from fine materials suspended in the sea water has nearly no component sensible in MSS-4 and MSS-5 channels.

    In the Yedo era, the Kamigata area was the place of dispatch of new cultures and was the seat of the economy. However, because natural disasters happened frequently, the economic differential between the central area and the provinces grew wider. The families who suffered poverty sold their daughters to the licensed quarters. Moreover, among the general public, there were a lot of foundlings and women who had abortions. Indeed, we can find these phenomena throughout the Yedo era. Early in the era, such cases were regarded as very common; for example, in IHARA Saikaku works, which describes scenes in Osaka early in the Yedo era, there are a lot of descriptions of foundlings and women who had abortions as common social phenomena. However, in the middle of the era, these phenomena came to be considered sins, as they were in Saikaku's works. This transition period of conceptions about foundlings or abortions coincided with changes in technology in obstetrics. Early in the era when dystocia occurred, both mothers and babies could only be expected to die, and in the middle, after the invention of Kaiseijutsu, which was designed by KAGAWA Gen'etsu, obstetricians could help a lot of women in childbirth. However, when abortions came to be regarded as a sin, people accepted Kaiseijutsu because of the concept of life and because it could help women in childbed and babies as medicine, before everything else.

    Mycobacterium tuberculosis Beijing lineage is highly prevalent in Japan. The aim of the present study was to describe the population structure of the Beijing lineage in this country based on 12-, 15-, and 21-loci MIRU-VNTR genotyping schemes. The MIRU-VNTR patterns of Beijing strains from Okinawa, Ryukyu Islands were compared to those recently published from the Osaka-Kobe megalopolis of the main island of Japan, Honshu (Wada et al., 2009). We also compared proportions of "modern/typical" vs. "ancient/atypical" Beijing strains as defined by structure of the NTF locus. Contrarily to the 12-loci Minimum Spanning Tree (MST), the 15- and 21-loci trees allowed the distinction of two groups of strains in Okinawa. A 12-loci MIRU-VNTR pattern (223325173533) corresponding to MIRU international type MIT17 was identified as the most prevalent Beijing genotype in Japan. In the SITVIT2 database, this pattern was found to be disseminated worldwide and corresponded to the most widely distributed Beijing profile in East Asia and former USSR countries. A comparison of 15- and 21-loci MIRU-VNTR patterns showed that two loci (QUB-4156 and Mtub21) were most polymorphic in our study, and could be potential candidates to distinguish between NTF locus based subclassification of Beijing strains. High-resolution VNTR typing using 15- and 21-loci underlined an evolutionarily distinct "ancient/atypical" subpopulation of the Beijing genotype in Okinawa as well as a subgroup of strains closely related to "modern/typical" Beijing strains observed in Osaka/Kobe.

    Raised bed river should be a typical artificial landforms caused by the environmental changes in the upstream region of rivers. Typical raised bed rivers have developed in the western part of Japan, especially Kyoto, Osaka, Nara, Shiga region, induced by artificial fixing of alluvial river channels and increasing of bed load in floods. Inter-disciplinal approach of archaeological and geological investigations in southern Kyoto region, Kizu River, revealed that the raising of river bed started from 14th century and accelerated the raising rate from 17th century. The development of upstream mountainous area, deforestation and keeping grass field in long term period, led to increasing landslides and topsoil erosion in the mountainous slope, so that the bare mountains were common scenery around the advanced developed region in Japan during the ages of raised bed rivers from 14th to 19th century. The backgrounds of the beginning of these exhaustive developments in mountainous slope surrounding of urban region should be reflected in the social changes going on 14th century. Social confusion continues to demise of ancient order forced to take the regional social and economic integration and generated the new integrated villages that they interested to increasing food production by cultivation needed to large quantity of grass supplied from surrounding grass (bare) mountains. The classic landscape of raised bed rivers in Japan initiated from the mediaeval ages shows the history of interaction between environmental changes and ancient society.

    2016-10-01

    High-density compression of DT to one thousand times its liquid density is the critical path of inertial fusion and was demonstrated in Japan and US in late 1980's. The Osaka group has achieved high-density compression that meets one of the critical requirements for thermonuclear ignition and bum. Although the compression densities were well reproduced by computer simulations, the neutron yields were much lower than the simulation predictions by three orders of magnitudes, suggesting catastrophic collapse of a hot spark, from which thermonuclear reactions are triggered. In order to overcome this difficulty the international ICF community has adopted two approaches: one is to generate a larger hot spark than the mixed layer with MJ-Class lasers, such as NIF and LMJ. The other approach is to externally heat the compressed fuel. The second approach is the fast ignition. After the proof-of-concept experiment in 2002, we started the Fast Ignition Realization Experiment (FlREX) project to complete the world most powerful high-energy peta-watt laser "LFEX" as a heating laser.

    Problems on groundwater contamination in Japan are briefly summarized in this paper. Although normal physical conditions in Japan restrict the possibilities of groundwater contamination, human activities are threatening groundwater resources. A survey by the Environment Agency of Japan showed nationwide spreading of organic substances, such as trichloroethylene as well as nitrogen compounds. Synthetic detergents have also been detected even in rural areas and in deep confined aquifers, although their concentrations are not as high. Public awareness of agrichemical or pesticides abuse, especially from golf courses, is apparent. Other problems such as nitrate-nitrogen, leachate from landfills, and the leaking of underground storage tanks are also discussed.

    The purpose of this JTEC study is to evaluate Japan's electronic manufacturing and packaging capabilities within the context of global economic competition. To carry out this study, the JTEC panel evaluated the framework of the Japanese consumer electronics industry and various technological and organizational factors that are likely to determine who will win and lose in the marketplace. This study begins with a brief overview of the electronics industry, especially as it operates in Japan today. Succeeding chapters examine the electronics infrastructure in Japan and take an in-depth look at the central issues of product development in order to identify those parameters that will determine future directions for electronic packaging technologies.

    1997-06-01

    In an interview with the Japanese Family Planning Association (FPA), Alexander Sanger, president of Margaret Sanger Center International (MSCI), Planned Parenthood of New York City (PPNYC), sketched the history of the clinic and research center founded by his grandmother, Margaret Sanger. The first person to come to the clinic from another country for training was Shidzue Kato of Japan. In addition to providing FP services and training, the clinic became known as a research center for new methods of contraception. After its 1973 merger with PPNYC, the clinic continued to function as an international training center with funding from the US Agency for International Development and the UN Population Fund. MSCI works with governments and nongovernmental organizations worldwide and focuses on 1) improving quality of care in FP clinics, 2) integrating FP into primary health-care centers, 3) promoting family life education, 4) improving male involvement in FP, 5) HIV/AIDS education, and 6) training FPAs in FP and women's rights advocacy. Sanger noted that FP advocates in the US were unsuccessful in lobbying to prevent a decrease in US funding of international FP programs (down to $385 million in 1996 from $548 million in 1994). Sanger called upon Japan and European countries to help make US politicians understand that providing FP funding is a responsibility of the most powerful nation in the world. Rather than cutting support, the US should be increasing funds for international FP efforts in conjunction with the US commitment to the International Conference on Population and Development's Program of Action.

    The aim of this study was to investigate the clinical characteristics and practice pattern of patients with dry eye disease (DED) in eye clinics across Japan. A multi-center, cross-sectional study was conducted among patients with DED who visited eye clinics in Japan. Subjective symptoms, patient's background, ocular surface features, and tear function were evaluated. Main outcome measures were tear break-up time (TBUT), Schirmer I value, kerato-conjunctival staining score, and dry eye symptom questionnaire score. Initially, 463 subjects were enrolled, and 449 cases (63 male and 386 female; mean age, 62.6 ± 15.7 years) were included in the final analysis. Overall, 94.9% of patients had a shortened TBUT (≤5 s), and 54.6% had an aqueous tear deficiency (Schirmer I value ≤5 mm). The most prevalent subtype of dry eye was aqueous-deficient dry eye, which was present in 35.0% of all patients, followed by short-BUT-type dry eye, which was seen in 26.7%. The two most common DED subtypes were aqueous-deficient and short-BUT-type dry eye. Shortened TBUT is the most common feature of dry eye, regardless of subtype. The current treatment choice mainly consisted of hyaluronic acid, two novel mucin secretagogues, diquafosol and rebamipide, and steroidal eye drops.

In April 2000, the public nursing care insurance system was enacted by the Japanese government. After its enaction, care equipment came under scrutiny, but the situation regarding the installation of equipment is not fully understood. In order to understand the present state of care equipment in nursing facilities for the elderly, we conducted a workplace and interview survey. The surveyed facilities were 10 special nursing homes for the elderly in Osaka Prefecture which were established after April 2002. The average number of elderly residents was 79.0, the average value of degree of care was 3.52, and the average number of caregivers was 28.3 per facility. We found all facilities had installed some kinds of bathing equipment: stretcher type, 9 facilities; bath-chair type, 8 facilities. In the facilities with bath-chairs, 6 facilities had special bathtubs, and 6 facilities had general bathtubs. However, all facilities had the working principle that transfer should be done manually, and the equipment for transfer such as a lifts, a transfer and roller board were not be installed. In changing diapers, bed height adjustment was not possible. And the Japanese standard type of wheelchair has a non-detachable armrest, creating a structural barrier when transferring elderly people from a wheelchair to a toilet seat. At all facilities the basis of care was that caregivers should do it manually. In particular, all facilities had only a weak recognition of the risks of transfer. This investigation shows that facilities for the elderly should rethink elderly care based on a reduction of care load and most importantly protection of caregivers' health.

    To estimate the cost of treating a tuberculosis (TB) case and to analyse TB-related medical service utilisation, a cost-of-illness study was conducted for all patients with a primary diagnosis of TB admitted to a public hospital in Japan. Retrospective analysis by abstracting in- and out-patient medical records of 57 paediatric patients diagnosed with TB during 1993-1998 at a public hospital in Osaka prefecture. Costs were estimated based on third party's payer perspectives according to the service utilisation pattern. In addition to cost data, sociodemographic information and service utilisation pattern were also extracted from the medical records. Cost of preventing a case of TB was abstracted from the published literature. The average cost of treatment was 8384 US dollars (95%CI 5667-11,099), while the average length of hospitalisation was 63 days (95%CI 43-84). Based on 20-80% vaccine efficacy, the cost of preventing a case of TB was 35,950-175,862 US dollars. In univariate analysis, site of TB (P = 0.04) was significantly associated with TB treatment cost, while case-finding method (contact tracing, symptoms, etc.) was associated with length of hospitalisation (P = 0.03). Multivariate regression analysis, however, showed none of the factors to be significant predictors of TB treatment cost and length of hospital stay. The cost of treating a case of paediatric TB is much lower than that of preventing one. Japan's universal BCG vaccination policy should be re-examined in the light of economic, social and political issues.

    Compared with other countries, surveys of these parasites have been rarely performed in companion animals of Japan in spite of their significance for public health. Here, we investigated pet dogs and cats in Japan for the first time, and genetically analyzed the isolates to evaluate the risk of zoonotic infections. Seventy-seven fecal samples were collected from privately owned dogs and 55 samples from owned cats in Osaka city, Japan. Cryptosporidium oocysts were identified in 3/77 dogs (3.9%) and 7/55 cats (12.7%), and Giardia infection in 2/77 dogs (2.6%) and 1/55 cats (1.8%). Amplification of the target regions for genotyping was successful, Cryptosporidium isolates in dogs and cats were identified as C. canis and C. felis, respectively, and those of Giardia in dogs and cats were G. intestinalis Assemblages D and F. The discharge period of the oocysts varied within 3-16 weeks and that of the cysts was 12 weeks. To date, zoonotic types of both parasites have been identified in other animals in Japan, and further large-scale studies are needed to determine the distribution of zoonotic genotypes in these animals, especially those closely associated with humans.

    This conference on ``Multi-wavelength AGN Surveys and Studies'' has provided a detailed look at the explosive growth over the past decade, of available astronomical data from a growing list of large scale sky surveys, from radio-to-gamma rays. We are entering an era were multi-epoch (months to weeks) surveys of the entire sky, and near-instantaneous follow-up observations of variable sources, are elevating time-domain astronomy to where it is becoming a major contributor to our understanding of Active Galactic Nuclei (AGN). While we can marvel at the range of extragalactic phenomena dispayed by sources discovered in the original ``Markarian Survey'' - the first large-scale objective prism survey of the Northern Sky carried out at the Byurakan Astronomical Observtory almost a half-century ago - it is clear from the talks and posters presented at this meeting that the data to be be obtained over the next decade will be needed if we are to finally understand which phase of galaxy evolution each Markarian Galaxy represents.

  14. The E693Δ (Osaka) mutation in amyloid precursor protein potentiates cholesterol-mediated intracellular amyloid β toxicity via its impaired cholesterol efflux.

    It has been shown that amyloid β (Aβ) secretion regulates cholesterol efflux from cells and that the E693Δ (Osaka) mutation in amyloid precursor protein (APP) promotes intracellular accumulation of Aβ and thus reduces its secretion. These findings led us to speculate that APP with the Osaka mutation (APPOSK ) might have a defect in cholesterol efflux and thus cause cellular malfunction. We therefore examined the effects of this mutation on intracellular cholesterol transport and efflux in cultured cells. Upon cholesterol loading, APPOSK -expressing cells exhibited higher levels of cellular cholesterol than wild-type APP-expressing cells, suggesting impaired cholesterol efflux. It is known that, after its internalization, cholesterol is transported from the endosomes to the endoplasmic reticulum (ER) and Golgi apparatus and then to the plasma membrane. In APPOSK -expressing cells, cholesterol accumulated with Aβ in the ER and Golgi apparatus and alone in endosomes/lysosomes. These results imply that the mutation-induced disturbance of Aβ trafficking from the ER to the plasma membrane affects cholesterol transport to cause cholesterol accumulation in the ER and Golgi apparatus and, consequently, in endosomes. Furthermore, we detected an enhanced mitochondrial accumulation of Aβ and cholesterol in APPOSK -expressing cells, and this was accompanied by an increase in the generation of reactive oxygen species (ROS). The present findings suggest that Aβ trafficking is important for intracellular cholesterol transport and efflux and that the Osaka mutation potentiates cholesterol-dependent exacerbation of intracellular Aβ toxicity, i.e. Aβ-induced ROS generation, by disturbing Aβ-mediated cholesterol efflux from the cell.

    The Cluster Conference is a long-running conference series dating back to the 1960's, the first being initiated by Wildermuth in Bochum, Germany, in 1969. The most recent meeting was held in Nara, Japan, in 2003, and in 2007 the 9th Cluster Conference was held in Stratford-upon-Avon, UK. As the name suggests the town of Stratford lies upon the River Avon, and shortly before the conference, due to unprecedented rainfall in the area (approximately 10 cm within half a day), lay in the River Avon! Stratford is the birthplace of the `Bard of Avon' William Shakespeare, and this formed an intriguing conference backdrop. The meeting was attended by some 90 delegates and the programme contained 65 70 oral presentations, and was opened by a historical perspective presented by Professor Brink (Oxford) and closed by Professor Horiuchi (RCNP) with an overview of the conference and future perspectives. In between, the conference covered aspects of clustering in exotic nuclei (both neutron and proton-rich), molecular structures in which valence neutrons are exchanged between cluster cores, condensates in nuclei, neutron-clusters, superheavy nuclei, clusters in nuclear astrophysical processes and exotic cluster decays such as 2p and ternary cluster decay. The field of nuclear clustering has become strongly influenced by the physics of radioactive beam facilities (reflected in the programme), and by the excitement that clustering may have an important impact on the structure of nuclei at the neutron drip-line. It was clear that since Nara the field had progressed substantially and that new themes had emerged and others had crystallized. Two particular topics resonated strongly condensates and nuclear molecules. These topics are thus likely to be central in the next cluster conference which will be held in 2011 in the Hungarian city of Debrechen. Martin Freer Participants and Cluster'07

    The E693Δ (Osaka) mutation in APP is linked to familial Alzheimer's disease. While this mutation accelerates amyloid β (Aβ) oligomerization, only patient homozygotes suffer from dementia, implying that this mutation is recessive and causes loss-of-function of amyloid precursor protein (APP). To investigate the recessive trait, we generated a new mouse model by knocking-in the Osaka mutation into endogenous mouse APP. The produced homozygous, heterozygous, and non-knockin littermates were compared for memory, neuropathology, and synaptic plasticity. Homozygotes showed memory impairment at 4 months, whereas heterozygotes did not, even at 8 months. Immunohistochemical and biochemical analyses revealed that only homozygotes displayed intraneuronal accumulation of Aβ oligomers at 8 months, followed by abnormal tau phosphorylation, synapse loss, glial activation, and neuron loss. These pathologies were not observed at younger ages, suggesting that a certain mechanism other than Aβ accumulation underlies the memory disturbance at 4 months. For the electrophysiology studies at 4 months, high-frequency stimulation evoked long-term potentiation in all mice in the presence of picrotoxin, but in the absence of picrotoxin, such potentiation was observed only in homozygotes, suggesting their GABAergic deficit. In support of this, the levels of GABA-related proteins and the number of dentate GABAergic interneurons were decreased in 4-month-old homozygotes. Since APP has been shown to play a role in dentate GABAergic synapse formation, the observed GABAergic depletion is likely associated with an impairment of the APP function presumably caused by the Osaka mutation. Oral administration of diazepam to homozygotes from 6 months improved memory at 8 months, and furthermore, prevented Aβ oligomer accumulation, indicating that GABAergic deficiency is a cause of memory impairment and also a driving force of Aβ accumulation. Our findings suggest that the Osaka mutation

    The Internet has been widely used by medical institutes and hospitals around the world, however; its use for telemedicine is still low. The main reason for this is the availability of bandwidth and poor security through the net. Meanwhile, we have established and have been operating 'Cancer Information Network' among 11 Cancer Centers in Japan, mainly for Multipoint TV Conference using HDTV image. There are also similar projects among 9 cardiovascular centers in Japan. By March, all 240 national hospitals will have been connected by an IP network using an ATM backbone. The above network projects are operated independently, and have an 'Intranet' characteristics within them. There are also many hospitals and clinics connected to the Internet by commercial internet providers. To make a secure and efficient network between these medical networks and medical sites, we started the Medical Internet eXchange project (MDX project) constructing a Medical Network Operation Center to create a link between them. To provide the administrative policy of this project, we established the Medical Internet eXchange Association. We are planning to expand this project to Asian-Pacific countries using the Asian-Pacific Advanced Network (APAN), and also expand it to worldwide connections in the future. For this purpose, we are currently asking other countries to form a structure similar to MDX-Japan. The concept, hardware system, software system, firewall configuration, and routing policy will be also discussed.

    A major challenge for clinicians, pharmaceutical companies and regulatory agencies is to better understand the relative contributions of ontogeny and genetic variation to observed variability in drug disposition and response across the pediatric age spectrum from preterm and term newborns, to infants, children and adolescents. Extrapolation of adult experience with pharmacogenomics and personalized medicine to pediatric patients of different ages and developmental stages, is fraught with many challenges. Compared with adults, pediatric pharmacogenetics and pharmacogenomics involves an added measure of complexity as variability owing to developmental processes, or ontogeny, is superimposed upon genetic variation. Furthermore, some pediatric diseases have no adult correlate or are more prevalent in children compared with adults, and several adverse drug reactions are unique to children, or occur at a higher frequency in children. The primary objective of this conference was to initiate an ongoing series of annual meetings on ‘Pediatric Pharmacogenomics and Personalized Medicine’ organized by the Center for Personalized Medicine and Therapeutic Innovation and Division of Clinical Pharmacology and Medical Therapeutics at Children’s Mercy Hospitals and Clinics in Kansas City, MO, USA. The primary goals of the inaugural meeting were: to bring together clinicians, basic and translational scientists and allied healthcare practitioners, and engage in a multi- and cross-disciplinary dialog aimed at implementing personalized medicine in pediatric settings; to provide a forum for the presentation and the dissemination of research related to the application of pharmacogenomic strategies to investigations of variability of drug disposition and response in children; to explore the ethical, legal and societal implications of pharmacogenomics and personalized medicine that are unique to children; and finally, to create networking opportunities for stimulating discussion

    This report summarizes the International Conference on Fusion Reactor Materials (ICFRM-4) which was held December 4--9, 1989, in Kyoto, Japan, as well as the results of several workshops, planning meetings, and laboratory visits made by the travelers. The ICFRM-4 is the major forum to present and exchange information on materials research and development in support of the world's fusion development efforts. About 360 papers were presented by the 347 conference attendees. Highlights of the conference are presented. A proposal by the United States to host ICFRM-5 was accepted by the International Advisory Committee. ORNL will be the host laboratory. A meeting of the DOE/JAERI Annex I Steering Committee to review the US/Japan Collaborative Testing of First Wall and Blanket Structural Materials with Mixed Spectrum Fission Reactors was held at JAERI Headquarters on December 1. The Japanese emphasized the critical importance of a resumption of HFIR operation. Even though the HFIR outage has lasted three plus years this program has continued to provide new and important data on materials behavior which has particular relevance to ITER.

    Japan has been one of the most successful countries in the world in the realm of terrestrial robot applications. The panel found that Japan has in place a broad base of robotics research and development, ranging from components to working systems for manufacturing, construction, and human service industries. From this base, Japan looks to the use of robotics in space applications and has funded work in space robotics since the mid-1980's. The Japanese are focusing on a clear image of what they hope to achieve through three objectives for the 1990's: developing long-reach manipulation for tending experiments on Space Station Freedom, capturing satellites using a free-flying manipulator, and surveying part of the moon with a mobile robot. This focus and a sound robotics infrastructure is enabling the young Japanese space program to develop relevant systems for extraterrestrial robotics applications.

    While Japan is known more for its contributions to modern astronomy than its archaeoastronomical sites, there is still much about the culture's heritage that is of interest in the study of cultural astronomy. This case study provides an overview of historical considerations necessary to understand the place of astronomy in Japanese society as well as methodological considerations that highlight traditional approaches that have at times been a barrier to interdisciplinary research. Some specific areas of study in the cultural astronomy of Japan are discussed including examples of contemporary research based on interdisciplinary approaches. Japan provides a fascinating background for scholars who are willing to go beyond their curiosity for sites of alignment and approach the culture with a desire to place astronomical iconography in social context.

    2012-01-01

    Research into occupational asthma (OA) in Japan has been led by the Japanese Society of Occupational and Environmental Allergy. The first report about allergic OA identified konjac asthma. After that, many kinds of OA have been reported. Cases of some types of OA, such as konjac asthma and sea squirt asthma, have been dramatically reduced by the efforts of medical personnel. Recently, with the development of new technologies, chemical antigen-induced asthma has increased in Japan. Due to advances in anti-asthma medication, control by medical treatment tends to be emphasized and the search for causative antigens seems to be neglected. Furthermore, we do not have a Japanese guideline for diagnosis and management of OA. This article discusses the current state of OA in Japan. PMID:22872819

    This perspective piece gives an overview of the current situation of yoga therapy in Japan today. Traditional yoga in Japan suffered a serious setback in 1995 with a nerve gas terrorist attack on the Tokyo subway, which was carried out by a cult that recruited members through yoga classes. But with the increase in popularity with modern forms of yoga such as Iyengar yoga, Ashtanga yoga and hot yoga in the West, the general public in Japan today is forgetting its aversion to yoga and considers it to be something that can contribute to good health. In 2012, the Japan Yoga Therapy Society (JYTS) conducted a study on adverse events in yoga classes throughout Japan with the University of Kyushu School of Medicine, with support from the Ministry of Health, Labour and Welfare. This study indicated that more than half of people attending yoga classes have some form of chronic illness, with 42.3% receiving outpatient care. This survey was the beginning of growing interest from both the government and universities in yoga therapy. JYTS is beginning to make inroads into bringing yoga therapy into cancer and palliative care, senior citizen homes, alcohol and drug addiction rehabilitation, cardiovascular rehabilitation, and research on trauma and schizophrenia. While there are still limited opportunities for yoga therapists to work in mainstream healthcare services, there is growing interest among medical professionals in both physical and mental health.

    Measles virus (MV) is the causative agent for acute measles and subacute sclerosing panencephalitis (SSPE). Although numerous mutations have been found in the MV genome of SSPE strains, the mutations responsible for the neurovirulence have not been determined. We previously reported that the SSPE Osaka-2 strain but not the wild-type strains of MV induced acute encephalopathy when they were inoculated intracerebrally into 3-week-old hamsters. The recombinant MV system was adapted for the current study to identify the gene(s) responsible for neurovirulence in our hamster model. Recombinant viruses that contained envelope-associated genes from the Osaka-2 strain were generated on the IC323 wild-type MV background. The recombinant virus containing the M gene alone did not induce neurological disease, whereas the H gene partially contributed to neurovirulence. In sharp contrast, the recombinant virus containing the F gene alone induced lethal encephalopathy. This phenotype was related to the ability of the F protein to induce syncytium formation in Vero cells. Further study indicated that a single T461I substitution in the F protein was sufficient to transform the nonneuropathogenic wild-type MV into a lethal virus for hamsters. PMID:20719945

    In Japan, the main source of dioxins is incinerators. This study examined the relationship between the distance of schools from municipal waste incineration plants and the prevalence of allergic disorders and general symptoms in Japanese children. Study subjects were 450,807 elementary school children aged 6-12 years who attended 996 public elementary schools in Osaka Prefecture in Japan. Parents of school children completed a questionnaire that included items about illnesses and symptoms in the study child. Distance of each of the public elementary schools from all of the 37 municipal waste incineration plants in Osaka Prefecture was measured using geographical information systems packages. Adjustment was made for grade, socioeconomic status and access to health care per municipality. Decreases in the distance of schools from the nearest municipal waste incineration plant were independently associated with an increased prevalence of wheeze, headache, stomach ache, and fatigue (adjusted odds ratios [95% confidence intervals] for shortest vs. longest distance categories =1.08 [1.01-1.15], 1.05 [1.00-1.11], 1.06 [1.01-1.11], and 1.12 [1.08-1.17], respectively). A positive association with fatigue was pronounced in schools within 4 km of the second nearest municipal waste incineration plant. There was no evident relationship between the distance of schools from such a plant and the prevalence of atopic dermatitis or allergic rhinitis. The findings suggest that proximity of schools to municipal waste incineration plants may be associated with an increased prevalence of wheeze, headache, stomach ache, and fatigue in Japanese children.

    Recently, the hospital information systems (HIS) and anesthesia information management systems (AIMS) have been rapidly improved and have been introduced into the clinical practice in Japan drastically; however, few reports have detailed their influences on clinical practice. We here report our experience. We introduced HIS (EGMAIN-EX, Fujitsu Co., Ltd.) in our preoperative evaluation clinic and in the postoperative care unit. AIMS (ORSYS, Philips Electronics Japan) was introduced almost only to the intraoperative management. It became easy for us to acquire patient's information and to share it with the medical staffs in the other departments. However, we had to invest large human resources for the introduction and maintenance of the HIS and the AIMS. Though AIMS is more useful in anesthetic management than HIS, it seems to be more suitable for coordination with the medical staffs in the other departments to use HIS for perioperative management than to use AIMS.

    Tsukuba International Conference on Materials Science (TICMS) was held from 28th August to 6th September, 2013 for the celebration of 40th year anniversary of the University of Tsukuba. The conference was organized by the Division of Materials Science, in cooperation with the Graduate School of Pure and Applied Sciences, and Tsukuba Research Center for Interdisciplinary Materials Science. The purpose of the conference was to provide a unique forum for researchers and students working in various fields of materials science, which have been progressing so rapidly that no single society could cover. The conference consists of following seven workshops to cover various fields. The organizing committee believed that the conference gave all participants new insights into the widespread development of materials science and enhanced the circulation, among them, of information released at the conference. The organizers are grateful for the financial support from University of Tsukuba. This volume contains 25 selected papers from invited and contributed papers, all of which have been screened on the basis of the standard review process of the program committee. The editors express their thanks to those authors who contributed the papers published in this proceedings, which reflects the scientific value of the conference.

    In a surveillance system in Osaka City, Japan, 48 sporadic rotavirus A (RVA) infections were detected during 2008/2009-2011/2012 seasons. The G/P-genotypes of detected RVAs were G1P[8], G2P[4], G3P[8], G9P[4], and G9P[8]. Although G9P[4] is a rare genotype that had not been reported in Japan, it was the second most prevalent genotype, following G1P[8], and accounted for 35.3% of RVA cases in the 2011/2012 season. Further genotyping revealed that the G9P[4] strain had genotype 2 internal protein genes except for NSP3: G9-P[4]-I2-R2-C2-M2-A2-N2-T1-E2-H2. Among detected RVA strains, G9P[4] and some G9P[8] strains shared high nucleotide identity in VP7 and NSP3 genes. Phylogenetic and BLAST search analyses showed that the G9P[4] strain in Japan shared high nucleotide identity in genotype 2 genes with common G2P[4] strains circulating globally, but was distinct from other G9P[4] strains circulating worldwide. These results suggest that the G9P[4] strain in Japan may have emerged through an independent reassortment between G9P[8] and G2P[4]. Finally, the role of NSP3 protein in the circulating RVA from an amino acid comparison between T1- and T2-type NSP3 is discussed. These findings provide an important insight into less problematic combinations of circulating RVA genes derived from different genotypes. © 2015 Wiley Periodicals, Inc.

    Japanese encephalitis virus (JEV) infects numerous animal species including humans, horses and pigs. In this study, antibodies against JEV in feral raccoons (Procyon lotor), wild boars (Sus scrofa) and raccoon dogs (Nyctereutes procyonoides) in Japan were examined. The results showed that 40.7% (22 out of 54), 64.5% (40 out of 62), 69.1% (47 out of 68) and 0% (0 out of 20) of raccoons in Hyogo, Osaka, Wakayama and Hokkaido, respectively, had virus-neutralizing antibodies against JEV. In addition, 83.3% (30 out of 36) of wild boars and 63.2% (12 out of 19) of raccoon dogs in Wakayama were seropositive for JEV. There were no significant differences in seroprevalence of JEV between males and females or between adults and juveniles in these wild animals. JEV seroprevalence was compared between 37 raccoons and 30 wild boars captured in a limited period (November 2007 to February 2008), and we found that wild boars (86.7%) were significantly more seropositive for JEV antibody than raccoons (59.5%). In conclusion, JEV was prevalent in wild mammals, indicating that the possibility of JEV infection in humans may still be high in Japan. In addition, these wild animals may be good sentinels to estimate JEV infection risk in residents, as they live near humans and are not vaccinated.

    Sheridan, E. Marcia

    There are several reasons why Japan has one of the world's highest literacy rates. One reason is the nature of the Japanese written language, which employs a dual code of ideographs representing specific objects and a syllabary, in which each symbol represents a separate syllable. The syllable symbols are read consistently the same way, and…

    The JTEC panel found Japan to have significant leadership over the United States in the strategic area of electronic packaging. Many technologies and products once considered the 'heart and soul' of U.S. industry have been lost over the past decades to Japan and other Asian countries. The loss of consumer electronics technologies and products is the most notable of these losses, because electronics is the United States' largest employment sector and is critical for growth businesses in consumer products, computers, automobiles, aerospace, and telecommunications. In the past there was a distinction between consumer and industrial product technologies. While Japan concentrated on the consumer market, the United States dominated the industrial sector. No such distinction is anticipated in the future; the consumer-oriented technologies Japan has dominated are expected to characterize both domains. The future of U.S. competitiveness will, therefore, depend on the ability of the United States to rebuild its technological capabilities in the area of portable electronic packaging.

    The JTEC Panel on Advanced Composites surveyed the status and future directions of Japanese high-performance ceramic and carbon fibers and their composites in metal, intermetallic, ceramic, and carbon matrices. Because of a strong carbon and fiber industry, Japan is the leader in carbon fiber technology. Japan has initiated an oxidation-resistant carbon/carbon composite program. With its outstanding technical base in carbon technology, Japan should be able to match present technology in the U.S. and introduce lower-cost manufacturing methods. However, the panel did not see any innovative approaches to oxidation protection. Ceramic and especially intermetallic matrix composites were not yet receiving much attention at the time of the panel's visit. There was a high level of monolithic ceramic research and development activity. High temperature monolithic intermetallic research was just starting, but notable products in titanium aluminides had already appeared. Matrixless ceramic composites was one novel approach noted. Technologies for high temperature composites fabrication existed, but large numbers of panels or parts had not been produced. The Japanese have selected aerospace as an important future industry. Because materials are an enabling technology for a strong aerospace industry, Japan initiated an ambitious long-term program to develop high temperature composites. Although just starting, its progress should be closely monitored in the U.S.

  12. Dutch surgery in Japan.

    van Gulik, Thomas M; Nimura, Yuji

    2005-01-01

    An isolation policy was adopted in feudal Japan from 1639 to 1853 owing to the fear of foreign influence. During those 200 years of isolation, all foreigners were withheld from the country with the exception of the Dutch, who were permitted to establish a trading post on a small island in the Bay of Nagasaki, called Decima. Western culture and science reached the Japanese exclusively through the Dutch on Decima. Health care on Decima was provided by Dutch barber-surgeons, who introduced Western surgical practice in Japan. Official interpreters were the only Japanese allowed on Decima. It was from among these interpreters that the first Japanese surgeons arose who, having mastered the Dutch language, translated several Dutch anatomic and surgical texts. Genpaku Sugita translated a Dutch anatomy textbook into Japanese, which was completed in 1774. This book, entitled Kaitai Shinsho [New Book on Anatomy], was the first Western scientific monograph to be translated entirely into Japanese. Several Dutch surgical schools were founded through which Dutch surgery, known in Japan as "surgery of the red-haired" was propagated. According to the custom of the surgical guilds in Holland, certificates were granted to Japanese apprentices who had completed their training in Dutch surgery. About 60 Dutch surgeons had served on Decima up to 1850, providing the basis for surgery to develop in Japan. Among them, Philipp Franz von Siebold was an exceptional scholar who also had a great impact in making Japanese culture known to the Western world.

    Background Pandemic influenza A(H1N1) virus infection quickly circulated worldwide in 2009. In Japan, the first case was reported in May 2009, one month after its outbreak in Mexico. Thereafter, A(H1N1) infection spread widely throughout the country. It is of great importance to profile and understand the situation regarding viral mutations and their circulation in Japan to accumulate a knowledge base and to prepare clinical response platforms before a second pandemic (pdm) wave emerges. Methodology A total of 253 swab samples were collected from patients with influenza-like illness in the Osaka, Tokyo, and Chiba areas both in May 2009 and between October 2009 and January 2010. We analyzed partial sequences of the hemagglutinin (HA) and neuraminidase (NA) genes of the 2009 pdm influenza virus in the collected clinical samples. By phylogenetic analysis, we identified major variants of the 2009 pdm influenza virus and critical mutations associated with severe cases, including drug-resistance mutations. Results and Conclusions Our sequence analysis has revealed that both HA-S220T and NA-N248D are major non-synonymous mutations that clearly discriminate the 2009 pdm influenza viruses identified in the very early phase (May 2009) from those found in the peak phase (October 2009 to January 2010) in Japan. By phylogenetic analysis, we found 14 micro-clades within the viruses collected during the peak phase. Among them, 12 were new micro-clades, while two were previously reported. Oseltamivir resistance-related mutations, i.e., NA-H275Y and NA-N295S, were also detected in sporadic cases in Osaka and Tokyo. PMID:21572517

    Measles virus (MV) is the causative agent of subacute sclerosing panencephalitis (SSPE). We previously reported that the F gene of the SSPE Osaka-2 strain is the major determinant of MV neurovirulence. Because the sites and extents of mutations differ among SSPE strains, it is necessary to determine the mutations responsible for the SSPE-specific phenotypes of individual viral strain. In this study, recombinant viruses containing the envelope-associated genes from the SSPE Osaka-1 strain were generated in the IC323 wild-type MV background. Hamsters inoculated with MV containing the H gene of the Osaka-1 strain displayed hyperactivity and seizures, but usually recovered and survived. Hamsters inoculated with MV containing the F gene of the Osaka-1 strain displayed severe neurologic signs and died. Amino acid substitutions in the heptad repeat A and C regions of the F protein, including a methionine-to-valine substitution at amino acid 94, play major roles in neurovirulence.

    The radionuclides released from the Fukushima Daiichi nuclear power plant in 2011 pose a health risk. In this study, we estimated the 1st-year average doses resulting from the intake of iodine 131 (131I) and cesium 134 and 137 (134Cs and 137Cs) in drinking water and food ingested by citizens of Fukushima City (∼50 km from the nuclear power plant; outside the evacuation zone), Tokyo (∼230 km), and Osaka (∼580 km) after the accident. For citizens in Fukushima City, we considered two scenarios: Case 1, citizens consumed vegetables bought from markets; Case 2, citizens consumed vegetables grown locally (conservative scenario). The estimated effective doses of 134Cs and 137Cs agreed well with those estimated through market basket and food-duplicate surveys. The average thyroid equivalent doses due to ingestion of 131I for adults were 840 µSv (Case 1) and 2700 µSv (Case 2) in Fukushima City, 370 µSv in Tokyo, and 16 µSv in Osaka. The average effective doses due to 134Cs and 137Cs were 19, 120, 6.1, and 1.9 µSv, respectively. The doses estimated in this study were much lower than values reported by the World Health Organization and the United Nations Scientific Committee on the Effects of Atomic Radiation, whose assessments lacked validation and full consideration of regional trade in foods, highlighting the importance of including regional trade. The 95th percentile effective doses were 2–3 times the average values. Lifetime attributable risks (LARs) of thyroid cancers due to ingestion were 2.3–39×10−6 (Case 1) and 10–98×10−6 (Case 2) in Fukushima City, 0.95–14×10−6 in Tokyo, and 0.11–1.3×10−6 in Osaka. The contributions of LARs of thyroid cancers due to ingestion were 7.5%–12% of all exposure (Case 1) and 12%–30% (Case 2) in Fukushima City. PMID:25390339

    The radionuclides released from the Fukushima Daiichi nuclear power plant in 2011 pose a health risk. In this study, we estimated the 1st-year average doses resulting from the intake of iodine 131 (131I) and cesium 134 and 137 (134Cs and 137Cs) in drinking water and food ingested by citizens of Fukushima City (∼50 km from the nuclear power plant; outside the evacuation zone), Tokyo (∼230 km), and Osaka (∼580 km) after the accident. For citizens in Fukushima City, we considered two scenarios: Case 1, citizens consumed vegetables bought from markets; Case 2, citizens consumed vegetables grown locally (conservative scenario). The estimated effective doses of 134Cs and 137Cs agreed well with those estimated through market basket and food-duplicate surveys. The average thyroid equivalent doses due to ingestion of 131I for adults were 840 µSv (Case 1) and 2700 µSv (Case 2) in Fukushima City, 370 µSv in Tokyo, and 16 µSv in Osaka. The average effective doses due to 134Cs and 137Cs were 19, 120, 6.1, and 1.9 µSv, respectively. The doses estimated in this study were much lower than values reported by the World Health Organization and the United Nations Scientific Committee on the Effects of Atomic Radiation, whose assessments lacked validation and full consideration of regional trade in foods, highlighting the importance of including regional trade. The 95th percentile effective doses were 2-3 times the average values. Lifetime attributable risks (LARs) of thyroid cancers due to ingestion were 1.7-37×10-6 (Case 1) and5.6-79×10-6 (Case 2) in Fukushima City, 0.73-13×10-6 in Tokyo, and 0.04-0.49×10- 6 in Osaka. The contributions of LARs of thyroid cancers due to ingestion were 5.4%-11% of all exposure (Case 1) and 11%-25% (Case 2) in Fukushima City [corrected].

    This issue of Journal of Physics: Condensed Matter is dedicated to results in the field of strongly correlated electron systems under multiple-environment. The physics of strongly correlated electron systems (SCES) has attracted much attention since the discovery of superconductivity in CeCu_2 Si_2 by Steglich and his co-workers a quater-century ago. Its interest has been intensified by the discovery of high-Tc superconductivity in a series of cuprates with layered perovskite structure which are still under active debate. The present issue of Journal of Physics: Condensed Matter present some aspects of SCES physics on the basis of activities of a late project "Centre-Of-Excellence" supported by MEXT (Ministry of Education, Sports, Science, Culture and Technology of the Japanese Government). This project has been performed by a condensed matter physics group in the faculties of science and engineering science of Osaka University. Although this project also covers correlated phenomena in optics and nano-scale systems, we focus here on the issues of SCES related to superconductivity, mainly unconventional. The present issue covers the discussions on a new mechanism of superconductivity with electronic origin (critical valence fluctuation mechanism), interplay and unification of magnetism and superconductivity in SCES based on a systematic study of NQR under pressure, varieties of Fermi surface of Ce- and U-based SCES probed by the de Haas-van Alphen effect, electronic states probed by a bulk sensitive photoemission spectroscopy with soft X-ray, pressure induced superconductivity of heavy electron materials, pressure dependence of superconducting transition temperature based on a first-principle calculation, and new superconductors under very high-pressure. Some papers offer readers' reviews of the relevant fields and/or include new developments of this intriguing research field of SCES. Altogether, the papers within this issue outline some aspects of electronic states

    Even though Japan has mean annual precipitation of 1,714 mm and hundreds of dams and reservoirs constructed, frequent and severe droughts have occurred in wide regions of the country. Because of rapid economic growth and concentrations of population in urban areas, water demands in large cities have stressed reliability of water supply systems and necessitated the development of new water resources with considerable economic and environmental costs. To alleviate these situations, wastewater reclamation and reuse have been implemented widely in major cities. This paper summarizes the current status of water reuse in Japan and discusses dominant uses of reclaimed water, emphasizing non-potable urban applications such as toilet flushing, industrial reuse, and environmental water.

    Activities on diode pumped alkali laser (DPAL) in Japan is reviewed. We have started alkali laser works in 2011, and currently, we are the only players in Japan. Our interests are application oriented, and it is not only defense but also industrial. DPAL is a good candidate as a source of remote laser machining, thanks to its scalability and extremely good beam quality. We are studying on scientific and engineering problems of Cs DPAL with a small-scale apparatus. A commercial diode laser with volume Bragg grating outcoupler is used to pump the gain cell longitudinally. A 6.5 W continuous-wave output with optical to optical efficiency of 56% (based on the absorbed power) has been achieved. Numerical simulation codes are developed to understand the physics of DPAL and to help future developments.

    The northeast coast of Hokkaido and Kunashir Island, Japan (44.0N, 143.0E) are seen bordered by drifting sea ice. The sea ice has formed a complex pattern of eddies in response to surface water currents and winds. Photos of this kind aid researchers in describing local ocean current patterns and the effects of wind speed and direction on the drift of surface material, such as ice floes or oil. Kunashir is the southernmost of the Kuril Islands.

    Although the 1995 Tokyo subway sarin attack probably was the most widely reported terrorist event in Japan to date (5,500 injured, 12 dead), the country has suffered numerous other large terrorism-related events in recent decades, including bombings of the headquarters of Mitsubishi Heavy Industries in Tokyo in 1974 (207 injured, 8 dead), the Hokkaido Prefectural Government office building in Sapporo in 1976 (80 injured, 2 dead), and the Yosakoi-Soran Festival in Sapporo in 2000 (10 injured, none dead). Japan also has experienced two other mass-casualty terrorist events involving chemical releases, including the 1994 Matsumoto sarin attack (600 injured, 7 dead) and the 1998 Wakayama arsenic incident (67 injured, 4 dead). Until 1995, emergency management in Japan focused on planning and preparedness at the local level for the frequent disasters caused by natural events. Since that time, substantial progress has been made in advancing emergency planning and preparedness for terrorism-related events, including the designation of disaster centers in each prefecture, the implementation of several education and training programs for nuclear, biological, and chemical terrorism, and the establishment of a national Anti terrorism Office within the Ministry of Health, Labor, and Welfare.

    The Japan International Cooperation Agency (JICA) contracted JOICFP to organize and implement the Population/Reproductive Health Course of the JICA Prospective Expert Training Program, held in Japan and Nepal from November 17 to December 19. The course was attended by seven experts, all co-medicals except for an IEC expert and a medical economic expert. This was the fourth such course and the third one organized and managed by JOICFP. It was conducted as part of Japanese official development assistance activities under the Global Issues Initiative (GII) on Population and AIDS. The course is designed to train Japanese technical experts in providing technical cooperation in Japanese government projects in developing countries. Four of the five participant's of the previous year's course are now working in developing countries in JICA-related projects. Two participants of the 1997 course had received overseas assignments by the end of the course. In Tokyo, participants were given an overview of international population, reproductive health, and bilateral assistance, as well as Japan's experience in family planning and maternal-child health. The team then went upon a 2-week study tour in Nepal. Noting that most of the trainees were women, participants suggested that more men be trained in future courses.

    To describe the incidence, clinical progress, visual outcome, and laboratory findings of equine keratomycosis in Japan.  Retrospective study of the medical records of horses clinically and mycologically diagnosed with keratomycosis at the Equine Hospitals of the Japan Racing Association from 2005 to 2011. The diagnosis of keratomycosis was confirmed in eight horses (40.0% of the 20 horses with infectious keratitis from which fungi and/or bacteria were isolated). Fungi recovered from corneal swabs were identified as Aspergillus flavus (4), Aspergillus niger (1), Fusarium solani (1), and Mortierella wolfii (2). All horses were treated medically with topical antifungals, and one horse was also treated surgically. The median of treatment period was 40 days. Two horses were rendered blind in the affected eye and the others retained vision. Equine keratomycosis comprises a considerable portion of infectious keratitis in Japan, and the causative fungi that we isolated had been isolated previously from horses with keratomycosis in other regions with the exception of M. wolfii. Culture and cytological examination of corneal lesions should be immediately performed on eyes with signs of keratitis, particularly on those not improving with antibacterial medication, as early initiation of aggressive antifungal treatment tended to result in better outcome and shorter treatment period. © 2012 American College of Veterinary Ophthalmologists.

    Dramatic changes in trihalomethanes of tap water caused by decreasing the chlorine dose from to break-point to zero at a pre-chlorination could be found during several years from starting the advanced treatment in Osaka Prefectural water utilities (from 1998 to 2002). In 1998 (break-point chlorination), chloroform was predominant (an average of 14.3 microg/L) and bromodichloromethane (5.96 microg/L), dibromochloromethane (4.19 microg/L) and bromoform (1.06 microg/L) were in the decreasing order. In contrast, in 1999 (chloramination), dibromochloromethane and bromodichloromethane were abundant trihalomethanes (6.61 and 5.72 microg/L) and followed by chloroform (4.14 microg/L) and bromoform (1.41 microg/L). Trihalomethane distribution in 2002 (non-chlorination) was almost the same as that in 1999.

    Although foreign body airway obstruction (FBAO) accounts for many preventable unintentional accidents, little is known about the epidemiology of FBAO patients and the effect of forceps use on those patients. This study aimed to assess characteristics of FBAO patients transported to hospitals by emergency medical service (EMS) personnel, and to verify the relationship between prehospital Magill forceps use and outcomes among out-of-hospital cardiac arrests (OHCA) patients with FBAO. We retrospectively reviewed ambulance records of all patients who suffered FBAO, and were treated by EMS in Osaka City from 2000 through 2007, and assessed the characteristics of those patients. We also performed a multivariate logistic-regression analysis to assess factors associated with neurologically favorable survival among bystander-witnessed OHCA patients with FBAO in larynx or pharynx. A total of 2,354 patients suffered from FBAO during the study period. There was a bimodal distribution by age among infants and old adults. Among them, 466 (19.8%) had an OHCA when EMS arrived at the scene, and 344 were witnessed by bystanders. In the multivariate analysis, Magill forceps use for OHCA with FBAO in larynx or pharynx was an independent predictor of neurologically favorable survival (16.4% [24/146] in the Magill forceps use group versus 4.3% [4/94] in the non-use group; adjusted odds ratio, 3.96 [95% confidence interval, 1.21-13.00], p = 0.023). From this large registry in Osaka, we revealed that prehospital Magill forceps use was associated with the improved outcome of bystander-witnessed OHCA patients with FBAO.

    As in other countries, the traditional doctor-patient relationship in the Japanese healthcare system has often been characterised as being of a paternalistic nature. However, in recent years there has been a gradual shift towards a more participatory-patient model in Japan. With advances in technology, the possibility to use digital technologies to improve patient interactions is growing and is in line with changing attitudes in the medical profession and society within Japan and elsewhere. The implementation of an online patient engagement platform is being considered by the Myotonic Dystrophy Registry of Japan. The aim of this exploratory study was to understand patients' views and attitudes to using digital tools in patient registries and engagement with medical research in Japan, prior to implementation of the digital platform. We conducted an exploratory, cross-sectional, self-completed questionnaire with a sample of myotonic dystrophy (MD) patients attending an Open Day at Osaka University, Japan. Patients were eligible for inclusion if they were 18 years or older, and were diagnosed with MD. A total of 68 patients and family members attended the Open Day and were invited to participate in the survey. Of those, 59 % submitted a completed questionnaire (n = 40). The survey showed that the majority of patients felt that they were not receiving the information they wanted from their clinicians, which included recent medical research findings and opportunities to participate in clinical trials, and 88 % of patients indicated they would be willing to engage with digital technologies to receive relevant medical information. Patients also expressed an interest in having control over when and how they received this information, as well as being informed of how their data is used and shared with other researchers. Overall, the findings from this study suggest that there is scope to develop a digital platform to engage with patients so that they can receive

    Water pollution by domestic sewage is one of the critical environmental problems in the early stage of urbanization with significant growth of population. In case of Osaka metropolitan area in Japan, the pollution was significant until 1970s, while it has been improved by the development of sewage treatment systems. However, removal of nitrogen needs the advanced process therefore relatively large part of dissolved inorganic nitrogen (DIN) is usually discharged by treated sewage effluent. Besides, increase of sewage-derived pollutant loads through the combined sewage systems during rainfall events is recognized as a new problem in recent years. However, the impacts of sewage-derived loads on the water environment of river and coastal area have not been fully evaluated in previous studies. In the present research, we aimed to examine the dynamics of sewage-derived nutrients in highly urbanized coastal rivers. Study area is located on the coastal area of Osaka bay in Seto Inland Sea, western Japan. Treated sewage effluent is discharged from three sewage treatment plants (KH, SU and SA) to a river and channels. Water and sediment samples were collected and electric conductivity (EC), chlorophyll-a (Chl.-a) and dissolved oxygen concentration (DO) were measured from the discharging points to few kilometers offshore at 100-300 m intervals. Nutrients (nitrogen, phosphorus and silica), nitrogen and carbon contents and stable isotope ratios (δ15N and δ13C) of particulate organic matter (POM) and sediment, nitrogen and oxygen stable isotope ratios (δ15N and δ18O) in nitrate (NO3-) were measured. Nitrate-nitrogen (NO3-N) concentration were significantly high near the discharging point then it decreased to offshore suggesting that impact zone of sewage effluent is about 1 km from the discharging point. Significant NO3-N uptake by phytoplankton as well as dilution process were suggested in the area. However, the impact zone expanded more than twofold during the rainfall

    Perfluorooctanoic acid (PFOA) has recently attracted attention as a potential health risk following environmental contamination. However, information detailing exposure to perfluorinated carboxylic acids (PFCAs) other than PFOA is limited. We measured the concentrations of PFCAs (from perfluorohexanoic acid to perfluorotetradecanoic acid) in serum samples obtained from patients in Japan (Sendai, Takayama, Kyoto and Osaka) between 2002 and 2009, Korea (Busan and Seoul) between 1994 and 2008 and Vietnam (Hanoi) in 2007/2008. Total PFCA levels (geometric mean) were increased from 8.9 ng mL(-1) to 10.3 ng mL(-1) in Japan; from 7.0 ng mL(-1) to 9.2 ng mL(-1) in Korea; and were estimated at 4.7 ng mL(-1) in Vietnam. PFCAs of greater length than PFOA were significantly increased in Sendai, Takayama and Kyoto, Japan, and levels of long-chain PFCAs exceeded PFOA levels in serum. Among these PFCAs, perfluoroundecanoic acid (PFUnDA) was the predominant component (28.5%), followed by perfluorononanoic acid (PFNA 17.5%), perfluorodecanoic acid (PFDA 7.9%), perfluorotridecanoic acid (PFTrDA 6.1%) and perfluorododecanoic acid (PFDoDA 1.8%). Odd-numbered PFCAs (PFNA, PFUnDA and PFTrDA) were also observed in Korea and Vietnam and their presence increased significantly in Korea between 1994 and 2007/2008. The proportion of long-chain PFCAs in serum was relatively high compared to reports in Western countries. Further investigations into the sources and exposure routes are needed to predict the future trajectory of these serum PFCA levels. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Desert dust is considered to be potentially toxic and its toxicity may change during long-range transportation. In Asian countries, the health effects of desert dust in different locations are not well understood. We therefore evaluated the city-combined and city-specific effects of Asian dust events on all-cause and cause-specific mortality in five populous cities in South Korea (Seoul) and Japan (Nagasaki, Matsue, Osaka and Tokyo). We obtained daily mean concentrations of Asian dust using light detection and ranging (lidar) between 2005 and 2011. We then evaluated city-specific and pooled associations of Asian dust with daily mortality for elderly residents (≥65 years old) using time-series analyses. Each 10 μg/m3 increase in the concentration of same-day (lag 0) or previous-day (lag 1) Asian dust was significantly associated with an elevated pooled risk of all-cause mortality (relative risk (RR): 1.003 [95% CI: 1.001-1.005] at lag 0 and 1.001 [95% CI: 1.000-1.003] at lag 1) and cerebrovascular disease (RR: 1.006 [95% CI: 1.000-1.011] at lag 1). This association was especially apparent in Seoul and western Japan (Nagasaki and Matsue). Conversely, no significant associations were observed in Tokyo, which is situated further from the origin of Asian dust and experiences low mean concentrations of Asian dust. Adverse health effects on all-cause and cerebrovascular disease mortality were observed in South Korea and Japan. However, the effects of Asian dust differed across the cities and adverse effects were more apparent in cities closer to Asian dust sources.

    Mussel watch program coupled with a pilot specimen bank at NIES was conducted from 1983 to 1987, and also from 1993 to 1994, and their results were compared to reveal temporal trends of coastal environment along Japan. Special emphasis was paid to reveal the change of ``background`` level of pollutants by collecting bivalves in remote islands. Several species of mussels (Mytilus edulis galloprovincialis, M. coruscus, Septifer virgatus, Pema viridis), oysters (Saxostrea mordax, Crassostrea gigas) and clams (Ruditapes philippinarum, Tridacna crocea) were collected to cover subfrigid to subtropical zones along Japan islands. The level of TBT decreased considerably between the above two intervals, i.e., from 0.12--0.01 {micro}g/g in mid 80`s to 0.03-n.d. (less than 0.01) {micro}g/g in 1993. This decrease may reflect the start of the regulation in 1990. The clam samples collected at Tokyo bay and stored in specimen bank were found to contain considerable levels (near 0.3 {micro}g/g) of TBT and TPT in 1980, and their levels were almost constant through mid and late 1980`s. Several heavy metals, including Cd, showed interesting spatial distribution patterns; their concentrations tend to be higher in less populated remote islands in western part of Japan than in densely populated areas. Cd concentrations, however, also show apparent correlation with Zn status of each organism (especially evident in Septifer sp.), and the interpretation of the results is not straightforward at this stage. Interestingly, a tropical green mussel, P. viridis, was found to be spreading in some densely populated area including Tokyo and Osaka bays.

    essential, not only for fusion energy development, but also for astro- and space research. Plasmas in different situations often have important features in common. Results obtained under various conditions, in the laboratory or in space, should therefore be compared and interrelated. The Göteborg conference emphasized more than the previous one, which was held in Nagoya, Japan, the astro- and space aspects, but there were still more contributions from the fusion and laboratory research. The fundamental plasma theory part was, however, the most extensive one in the programme. At the conference there were seventy invited talks, including six comprehensive talks addressed to all participants. The remaining sixtyfour invited talks were topical talks. Besides, we had received about 450 contributed papers. About 300 of them were given as posters, and most of the remaining ones were presented as orals. The set of one page abstracts of these contributed papers as well as the titles of the invited talks were collected in two volumes, which were sent to all participants a month before the conference. Another set, the four page papers, which had been carefully prepared by the authors for photoreproduction to one page papers, were published in a volume of proceedings of some 460 pages available at the conference. When trying to classify the contributions, it turned out that they fell naturally into four main categories, namely: General Theory Space and Astro Plasmas Fusion Laboratory Plasmas For practical reasons we had to divide the Abstracts into two Volumes, the first one including categories (1) and (2), and the second one the two remaining categories (3) and (4). In publishing the invited talks from the conference we had to handle a great number of extensive papers. It turned out to be natural to have also the invited papers published in two parts, as two separate numbers of Physica Scripta, the first one devoted to (1) General Theory, and (2) Space and Astro Plasmas, whereas the

    In March 1990, medical interchange between Japan and the Soviet Union began with a letter from the local health bureau of Khabarovsk. We visited Khabarovsk three times and Kamchatka once, and saw many hospitals and patients. Russian doctors of pediatrics visited Japan. Medical information was exchanged and discussed. The Japan-Russia Pediatric Society was established to perform interchange of medical information, technology and staff such as doctors, nurses and technicians between Japan and Russia, especially the Far East district of Russia. The Society meeting has been held three times: Tokyo (1991), Khabarovsk (1992) and Niigata (1993). It is necessary to continue the interchange between the two countries.

  20. The graying of Japan.

    Martin, L G

    1989-07-01

    Japan's rapidly aging population has become a top policy issue, especially as the increasing costs of pensions and medical care are debated. With the highest life expectancy on earth, the Japanese potentially face long periods of retirement, as well as the possibility of long periods of disability. Although family support of the elderly is thought to have been strong traditionally, the recent decline in co-residence with children is 1 indication that the way support is given may be changing. This issue is of particular concern to the government, which wants to avoid any greater responsibility for the elderly than is necessary given the dramatic population aging yet to come. The government is also encouraging employers to provide more employment opportunities for the elderly at the same time that it is trying to raise the eligibility age for the receipt of public pensions. There is resistance on the part of employers, however, because wages and retirement allowances in Japan are positively related to length of employment. Furthermore, it is not clear whether elderly Japanese of the future will be as willing to work, if they learn to enjoy increased leisure early in their careers. Nevertheless, it is unlikely that population aging will lead to Japan's economic decline. Although the savings rate may decline somewhat, restructuring of the economy and continued overseas investment should keep the economy growing in the long run. Important in both the care of the frail elderly and the continued growth of the economy will be the roles played by middle-aged Japanese women.

    Three kinds of astrogeodetic geoid maps for Japan are presented: one referred to the global (18, 18) geoid of the 1973 Smithsonian Standard Earth (III) (SE III), referred to the best-fitting ellipsoid of SE III, and one referred to the reference ellipsoid of the Tokyo datum. Interpolations of the deflection of the vertical are carried out by a least squares estimation method. The geoid height differences obtained are compared with solutions of satellite-derived station positions. Good agreement is found in a comparison with Doppler tracking stations.

  2. Ijime in Japan.

    This paper reviews the problem of ijime in Japan from a variety of perspectives, primarily through studies conducted in this country. The term ijime is not uniform in concept, open to different interpretations given the disparity in definitions among different circles, making precise assessment of the actual conditions difficult. Such being the case, what is needed is further study on the mechanisms and actual state of ijime accounting for the flow of the times, and compilation of research to enable the creation of ever more effective modes of prevention and intervention.

    An extensive outbreak of staphylococcal food poisoning occurred in Kansai district in Japan. As many as 13,420 cases frequently ingested dairy products manufactured by a factory in Osaka City. The main ingredient of these dairy products was powdered skim milk manufactured by a factory in Hokkaido. Staphylococcal enterotoxin A (SEA) (< or = 0.38 ng/ml) was detected in low-fat milk and approx. 3.7 ng/g in powdered skim milk. The total intake of SEA per capita was estimated mostly at approx. 20-100 ng. The assumed attack rate was considerably lower than those reported in previous outbreaks. SEA exposed at least twice to pasteurization at 130 degrees C for 4 or 2 s retained both immunological and biological activities, although it had been partially inactivated. The present outbreak was unusual in that the thermal processes had destroyed staphylococci in milk but SEA had retained enough activity to cause intoxication. PMID:12613743

    JOICFP President Shidzue Kato was influenced by and friends with Margaret Sanger from their initial meeting in 1920 to Sanger's death in 1966. Bruce Alfred is currently directing and producing a 90-minute documentary film about Sanger and her pioneering work in promoting the development and use of family planning. Once completed in the Spring of 1997, the film will be broadcast nationally in the US on Public Television. It is being produced with support from the National Endowment for the Humanities and several private foundations. Alfred interviewed Kato for three hours to gain insight into the life and legacy of Margaret Sanger. Sanger inspired Kato to make birth control her life's work. Kato spoke about how the prewar, pronatalist Japanese government allowed Sanger to visit Japan in 1922 only on the condition that she not speak about birth control. This official opposition and the subsequent reaction, however, actually fueled interest in Sanger and her message, and caused her ideas to become widely known among the Japanese public. While in Japan, Sanger did manage to discuss family planning, but in English in a closed meeting. Oddly enough, the government honored Sanger after the second World War with the highest award presented to non-Japanese. Kato noted how unfortunate it was that Sanger died in 1966 without witnessing the realization of the UNFPA.

  9. A 3D analysis of spatial relationship between geological structure and groundwater profile around Kobe City, Japan: based on ARCGIS 3D Analyst.

    Kobe city is located on the northern side of Osaka sedimentary basin, Japan, containing 1,000-2,000 m thick Quaternary sediments. After the Hanshin-Awaji Earthquake (January 17, 1995), a number of geological and geophysical surveys were conducted in this region. Then high-temperature anomaly of groundwater accompanied with high Cl concentration was detected along fault systems in this area. In addition, dissolved He in groundwater showed nearly upper mantle-like 3He/4He ratio, although there were no Quaternary volcanic activities in this region. Some recent studies have assumed that these groundwater profiles are related with geological structure because some faults and joints can function as pathways for groundwater flow, and mantle-derived water can upwell through the fault system to the ground surface. To verify these hypotheses, we established 3D geological and hydrological model around Osaka sedimentary basin. Our primary goal is to analyze spatial relationship between geological structure and groundwater profile. In the study region, a number of geological and hydrological datasets, such as boring log data, seismic profiling data, groundwater chemical profile, were reported. We converted these datasets to meshed data on the GIS, and plotted in the three dimensional space to visualize spatial distribution. Furthermore, we projected seismic profiling data into three dimensional space and calculated distance between faults and sampling points, using Visual Basic for Applications (VBA) scripts. All 3D models are converted into VRML format, and can be used as a versatile dataset on personal computer. This research project has been conducted under the research contract with the Japan Nuclear Energy Safety Organization (JNES).
