  1. [Establishment of anatomical terminology in Japan].

    The history of anatomical terminology in Japan began with the publication of Waran Naikei Ihan-teimŏ in 1805 and Chŏtei Kaitai Shinsho in 1826. Although the establishment of Japanese anatomical terminology became necessary during the Meiji era when many western anatomy books imported into Janan were translated, such terminology was not unified during this period and varied among translators. In 1871, Tsukumo Ono's Kaibŏgaku Gosen was published by the Ministry of Education. Although this book is considered to be the first anatomical glossary terms in Japan, its contents were incomplete. Overseas, the German Anatomical Society established a unified anatomical terminology in 1895 called the Basle Nomina Anatomica (B.N.A.). Based on this development, Kaibŏgaku Meishŭ which follows the BNA, by Buntarŏ Suzuki was published in 1905. With the subsequent establishment in 1935 of Jena Nomina Anatomica (J.N.A.), the unification of anatomical terminology was also accelerated in Japan, leading to the further development of terminology.

    A 6- to 7-MeV high-energy gamma-ray field, produced by the nuclear reaction of (19)F(p, αγ)(16)O, has been established at the Facility of Radiation Standards (FRS) in Japan Atomic Energy Agency for calibration purposes. Basic dosimetric quantities (i.e. averaged gamma-ray energy, air-kerma-to-dose equivalent conversion coefficients and air kerma rates at the point of test) have been precisely determined through a series of measurements using the NaI(Tl) spectrometer and an ionisation chamber coupled with an appropriate build-up material. The measurements obtained comply with values recommended by the International Organization for Standardization for an 'R-F field'. The neutron contamination component for the field has also been measured by means of a conventional neutron dose equivalent meter (the so-called neutron rem-counter) and determined to be ∼ 0.5 % of the total dose equivalent.

  3. The image of the atomic bomb in Japan before Hiroshima.

    2009-01-01

    This paper traces the roots of the image of the atomic bomb in Japan by investigating the various discourses on atomic energy and atomic weapons in Japanese literature prior to the bombing of Hiroshima in August 1945. Japan is a country that suffered an atomic attack and, at the same time, one of the countries that was engaged in atomic weapons research during the Second World War. During the war, the discourses on atomic weapons were not limited to the military or scientific communities, but included the general public, thus facilitating the creation of a shared image of the atomic bomb as an ultimate weapon. This paper examines how this image was created. This special issue deals with the comparison among different countries, but the purpose of my paper is to deepen this subject by illustrating the differences within a single country in different periods. This research aims to extend the historical perspective concerning the atomic bomb in Japan, and offers another way of looking at this both historical and contemporary issue.

    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

    Yatagai, Toyohiko

    2014-07-01

    At the present of the 21st century, optical technology became what must be in our life. If there is no optical technology, we cannot use optical equipments such as the camera, microscopes, DVD, LEDs and laser diodes (LDs). Optics is also the leading part in the most advanced scientific field. It is clear that the organization which does education and research is required in such a very important area. Unfortunately, there was no such organization in Japan. The education and research of light have been individually done in various faculties of universities, various research institutes, and many companies. However, our country is now placed in severer surroundings, such as the globalization of our living, the accelerated competition in research and development. This is one of the reasons why Utsunomiya University has established Center for Optical Research and Education (CORE) in 2007. To contribute to optical technology and further development of optical industry, "Center for Optical Research and Education (CORE), Utsunomiya University" promotes education and research in the field of the optical science and technology cooperatively with industry, academia and the government. Currently, 6 full professors, 21 cooperative professors, 2 visiting professors and 7 post-doctoral researchers and about 40 students are joined with CORE. Many research projects with industries, the local government of Tochigi as well as Japanese government. Optical Innovation Center has established in CORE by supporting of Japan Science and Technology Agency in 2011 to develop advanced optical technologies for local companies.

  3. Fukushima Daiichi Nuclear Accident; based on the Final Report of Atomic Energy Society of Japan

    2014-09-01

    The Atomic Energy Society of Japan (AESJ) published the Final Report of the AESJ Investigation Committee on Fukushima Daiichi NPS Accident in March 2014. The AESJ is responsible to identify the underlying root causes of the accident through technical surveys and analyses, and to offer solutions for nuclear safety. At the Fukushima Daiichi, Units 1 to 3, which were under operation, were automatically shut down at 14:46 on March 11, 2011 by the Tohoku District-off the Pacific Ocean Earthquake. About 50 minutes later, the tsunami flooded and destroyed the emergency diesel generators, the seawater cooling pumps, the electric wiring system and the DC power for Units 1, 2 and 4, resulting in loss of all power except for an air-cooled emergency diesel generator at Unit 6. Unit 3 lost all AC power, and later lost DC before dawn of March 13. Cooling the reactors and monitoring the results were heavily dependent on electricity for high-pressure water injection, depressurizing the reactor, low pressure water injection, and following continuous cooling. In Unit 3, for example, recent re-evaluation in August 2014 by TEPCO shows that no cooling water was injected into the reactor core region after 8 PM on March 12, leading to the fuel melting from 5:30 AM on March 13. Even though seawater was injected from fire engines afterwards, the rupture of pressure vessel was caused and the majority of melted fuel dropped into the containment vessel of Unit 3. The estimation of amount of radioactive materials such as Xe-133, I-131, Cs-137 and Cs-134, emitted to the environment from Units 1 to 3 is discussed in the presentation. Direct causes of the accident identified in the AESJ Report were, 1) inadequate tsunami measures, 2) inadequate severe accident management measures and 3) inadequate emergency response, post-accident management/mitigation, and recovery measures. These were caused by the following underlying factors, i.e., a) lack of awareness on the roles and responsibilities by

    In the Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-60U), a high- β p ELMy H-mode (high-poloidal-beta high-confinement-mode with edge localized mode) plasma was sustained with β N ˜2.7 for 7.4 s. Real-time neoclassical tearing mode (NTM) stabilization system was established and effective NTM suppression by early electron cyclotron (EC) wave injection was demonstrated. High fusion triple product of n i (0)τ E T i (0)=3.1×10 20 keVṡsṡm -3 was achieved using the negative-ion based neutral beam current drive with β N ˜2.5 and the bootstrap current fraction f BS ˜50%. In a hot electron regime, a high electron cyclotron current drive efficiency of 4.2×10 18 A/W/m 2 was achieved at T e ˜21 keV . Innovative current start-up scenario produced a current hole plasma with a very high f BS ˜90%. No accumulation of helium and carbon impurities was observed for internal transport barrier (ITB) plasmas. While argon impurity was accumulated, EC injection effectively exhausted it across ITB. In a regime of ELM disappearance, a clear correlation between the ELM frequency and the toroidal velocity at pedestal was observed. In the Japan Atomic Energy Research Institute Fusion Torus-2 Modified (JFT-2M), high beta plasmas were produced with full ferritic inside wall up to β N =3.3, where high recycling steady H-mode discharges were developed up to β N H 89 P ˜6 at n e /n GW ˜0.7-1.0 with ITB. JT-60U started long pulse experiment in late 2003 and JFT-2M will conduct wall stabilization experiment in early 2004. The modification of JT-60 to a fully superconducting coil tokamak is regarded as the national centralized tokamak facility program to accomplish the high beta steady-state research in a collisionless regime.

    The system of separating the dispensing and prescribing of drugs was legally established in 1956 on the recommendation of the American Pharmaceutical Association mission to Japan in 1949. However, serious disagreements between medical and pharmaceutical practitioners impeded implementation of the system, and the separation practice was not initiated until 1975 when the Japan Pharmaceutical Association and the Japan Medical Association established friendly relations. The system finally took root in the 1990s, and the Japan Pharmaceutical Association has since continued to further improve the system.

    Defining standardized methods requires careful consideration of the entire field and its applications. The International Field Emission Society (IFES) has elected a Standards Committee, whose task is to determine the needed steps to establish atom-probe tomography as an accepted metrology technique. Specific tasks include developing protocols or standards for: terminology and nomenclature; metrology and instrumentation, including specifications for reference materials; test methodologies; modeling and simulations; and science-based health, safety, and environmental practices. The Committee is currently working on defining terminology related to atom-probe tomography with the goal to include terms into a document published by the International Organization for Standards (ISO). A lot of terms also used in other disciplines have already been defined) and will be discussed for adoption in the context of atom-probe tomography.

  1. [The Chinese nuclear test and 'atoms for peace' as a measure for preventing nuclear armament of Japan: the nuclear non-proliferation policy of the United States and the introduction of light water reactors into Japan, 1964-1968].

    Japan and the United States signed in 1968 a new atomic energy agreement through which US light-water nuclear reactors, including those of the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company, were to be introduced into Japan. This paper studies the history of negotiations for the 1968 agreement using documents declassified in the 1990s in the US and Japan. After the success of the Chinese nuclear test in October 1964, the United States became seriously concerned about nuclear armament of other countries in Asia including Japan. Expecting that Japan would not have its own nuclear weapons, the US offered to help the country to demonstrate its superiority in some fields of science including peaceful nuclear energy to counter the psychological effect of the Chinese nuclear armament. Driven by his own political agenda, the newly appointed Prime Minister Eisaku Sato responded to the US expectation favorably. When he met in January 1965 with President Johnson, Sato made it clear that Japan would not pursue nuclear weapons. Although the US continued its support after this visit, it nevertheless gave priority to the control of nuclear technology in Japan through the bilateral peaceful nuclear agreement. This paper argues that the 1968 agreement implicitly meant a strategic measure to prevent Japan from going nuclear and also a tactic to persuade Japan to join the Nuclear Non -Proliferation Treaty.

    Tritium Process Laboratory (TPL) at the Japan Atomic Energy Research Institute (JAERI) has developed the Fuel Cleanup System (FCU) which accepts simulated fusion reactor exhaust and produces pure hydrogen isotopes and tritium-free waste. The major components are: a palladium diffuser, a catalytic reactor, cold traps, a ceramic electrolysis cell, and zirconium-cobalt beds. In 1988, an integrated loop of the FCU process was installed in the TPL and a number of hot'' runs were performed to study the system characteristics and improve system performance. Under the US-Japan collaboration program, the JAERI Fuel Cleanup System'' (JFCU) was designed and fabricated by JAERI/TPL for testing at the Tritium Systems Test Assembly (TSTA) in Los Alamos National Laboratory as a major subsystem of the simulated fusion fuel cycle. The JFCU was installed in the TSTA in early 1990.

    This study attempts to establish a system for hindcasting/forecasting the quantity of litter reaching a beach using an ocean circulation model, a two-way particle tracking model (PTM) to find litter sources, and an inverse method to compute litter outflows at each source. Twelve actual beach survey results, and satellite and forecasted wind data were also used. The quantity of beach litter was hindcasted/forecasted using a forward in-time PTM with the surface currents computed in the ocean circulation model driven by satellite-derived/forecasted wind data. Outflows obtained using the inverse method was given for each source in the model. The time series of the hindcasted/forecasted quantity of beach litter were found consistent with the quantity of beach litter determined from sequential webcam images of the actual beach. The accuracy of the model, however, is reduced drastically by intense winds such as typhoons which disturb drifting litter motion.

    The source of plutonium in sediments deposited at Nishiyama reservoir at Nagasaki was characterized by their (240)Pu/(239)Pu atom ratio. The average ratio was approximately 0.03, except in two layers. The main source of the plutonium was the Nagasaki atomic bomb. The plutonium continues to flow into the reservoir even now. The (240)Pu/(239)Pu atom ratios in two layers were higher than the average, which showed that plutonium in these layers were made of those of nuclear tests added to those of the atomic bomb.

    Recently, populations of Castanopsis cuspidata have often expanded into secondary forests in western Japan. To determine the establishment processes of this species, we analyzed its spatial distribution in a secondary forest dominated by Quercus variabilis and Quercus serrata that is located adjacent to a stand dominated by C. cuspidata. Saplings, defined as >or=30 cm stem length (SL) and <5 cm diameter at breast height (DBH), were abundant and their size distribution was inversely J-shaped, indicating continuous recruitment. Although seedlings (SL < 30 cm) and small saplings (30 or=40 m from the nearest adults, suggesting that there is animal-aided dispersal of acorns. The distribution of larger-sized individuals (>or=100 cm SL) of C. cuspidata was unrelated to distance from the nearest flowering C. cuspidata or dominant Quercus species (>or=5 cm DBH), but was associated with dead Pinus densiflora trees, which were abundant at the site. Thus, the establishment of C. cuspidata in this forest is controlled mainly by two factors, viz. patterns of acorn dispersal by animals, and forest disturbance regime (i.e., deaths of pine trees).

    Surface seawater samples were collected from a site in the vicinity of the nuclear fuel reprocessing facility at Rokkasho, Japan and sites along the Japan Sea coast. (239+240)Pu activities and (240)Pu/(239)Pu atom ratios were determined by alpha-spectrometry and isotope-dilution sector-field ICP-MS. The (240)Pu/(239)Pu atom ratio with the mean value of 0.227 +/- 0.006 was significantly higher than the mean global fallout ratio of 0.18. The contribution of the Pacific Proving Grounds close-in fallout was estimated to be 33% of the (239+240)Pu.

    This is an analysis of the work of the Atomic Bomb Casualty Commission, an American agency which studied the effects of radiation on survivors of the atomic bombings at Hiroshima and Nagasaki, Japan, 1947-1975. Funded by the U.S. Atomic Energy Commission and directed by the National Academy of Sciences-National Research Council, the ABCC was the largest and longest medical study of the estimated 300,000 survivors. The morphological genetics study dominated the ABCCs first decade. James Neel and his principal collaborator William J. Schull tracked more than 76,000 pregnancies. Their results (1956) suggested the bombs radiation had no detectable impact on the offspring of survivors. Though geneticists knew that radiation caused heritable mutations in experimental organisms such as Drosophila, and believed it caused mutations in humans, the Neel-Schull findings were not a surprise. The practical difficulties of the study, and the relatively small increase in abnormal births to be expected, made a finding of significant effects unlikely. The Neel-Schull approach reflected the scientific debate over genetic load, and the Muller-Dobzhansky classical-balance controversy. Yet the findings also reflected the post-war debate over atomic energy and weapons testing. Many extra-scientific forces militated against a finding of positive effects at Hiroshima and Nagasaki. Negative findings were consistent with the needs of the Atomic Energy Commission, the State Department and the U.S. military. This dissertation explores how both the scientific debate about genetic load, and the political debate about atmospheric weapons testing, shaped this complex epidemiological study.

    JAEA (Japan Atomic Energy Agency) manages 2 tritium handling laboratories: Tritium Processing Laboratory (TPL) in Tokai and DEMO-RD building in Rokkasho. TPL has been accumulating a gram level tritium safety handling experiences without any accidental tritium release to the environment for more than 25 years. Recently, our activities have focused on 3 categories, as follows. First, the development of a detritiation system for ITER. This task is the demonstration test of a wet Scrubber Column (SC) as a pilot scale (a few hundreds m{sup 3}/h of processing capacity). Secondly, DEMO-RD tasks are focused on investigating the general issues required for DEMO-RD design, such as structural materials like RAFM (Reduced Activity Ferritic/Martensitic steels) and SiC/SiC, functional materials like tritium breeder and neutron multiplier, and tritium. For the last 4 years, we have spent a lot of time and means to the construction of the DEMO-RD facility and to its licensing, so we have just started the actual research program with tritium and other radioisotopes. This tritium task includes tritium accountancy, tritium basic safety research such as tritium interactions with various materials, which will be used for DEMO-RD and durability. The third category is the recovery work from the Great East Japan earthquake (2011 earthquake). It is worth noting that despite the high magnitude of the earthquake, TPL was able to confine tritium properly without any accidental tritium release.

    After the Fukushima Daiichi Nuclear Power Plant accident in March 2011, concentrations of cesium isotopes (133Cs, 134Cs, and 137Cs) were measured in zooplankton collected in the Pacific off the east coast of Japan from May 2012 to February 2015. The time series of the data exhibited sporadic 137Cs concentration peaks in zooplankton. In addition, the atom ratio of 137Cs/133Cs in zooplankton was consistently high compared to that in ambient seawater throughout the sampling period. These phenomena cannot be explained fully by the bioaccumulation of 137Cs in zooplankton via ambient seawater intake, the inclusion of resuspended sediment in the plankton sample, or the taxonomic composition of the plankton. Autoradiography revealed highly radioactive particles within zooplankton samples, which could be the main factor underlying the sporadic appearance of high 137Cs concentrations in zooplankton as well as the higher ratio of 137Cs/133Cs in zooplankton than in seawater.

Long pulse production and acceleration of the negative ion beams have been independently carried out. The long pulse production of the high current beams has achieved 100 s at the beam current of 15 A by modifying the JT-60 negative ion source. The pulse duration time is increased three times longer than that before the modification. As for the acceleration, a pulse duration time has been also extended two orders of magnitudes from 0.4 s to 60 s. The developments of the negative ion source and acceleration at JAEA are well in progress towards the realization of the negative ion sources and accelerators for fusion applications.

    A magnitude 9.0 earthquake and subsequent tsunami occurred in the Pacific Ocean off northern Honshu, Japan, on 11 March 2011 which caused severe damage to the Fukushima Dai-ichi Nuclear Power Plant. This accident has resulted in a substantial release of radioactive materials to the atmosphere and ocean, and has caused extensive contamination of the environment. However, no information is available on the amounts of radionuclides such as Pu isotopes released into the ocean at this time. Investigating the background baseline concentration and atom ratio of Pu isotopes in seawater is important for assessment of the possible contamination in the marine environment. Pu-239 (half-life: 24,100 years), Pu-240 (half-life: 6,560 years) and Pu-241 (half-life: 14.325 years) mainly have been released into the environment as the result of atmospheric nuclear weapons testing. The atom ratio of Pu-240/Pu-239 is a powerful fingerprint to identify the sources of Pu in the ocean. The Pu-239 and Pu-240 inventories and Pu-240/Pu-239 atom ratios in seawater samples collected in the western North Pacific off Sanriku before the accident at Fukushima Dai-ichi Nuclear Power Plant will provide useful background baseline data for understanding the process controlling Pu transport and for distinguishing additional Pu sources. Seawater samples were collected with acoustically triggered quadruple PVC sampling bottles during the KH-98-3 cruise of the R/V Hakuho-Maru. The Pu-240/Pu-239 atom ratios were measured with a double-focusing SF-ICP-MS, which was equipped with a guard electrode to eliminate secondary discharge in the plasma and to enhance overall sensitivity. The Pu-239 and Pu-240 concentrations were 2.07 and 1.67 mBq/m3 in the surface water, respectively, and increased with depth; a subsurface maximum was identified at 750 m depth, and the concentrations decreased with depth, then increased at the bottom layer.

    The twelve GPS buoys that have been established along the Pacific coast of Japan succeeded to record the tsunami due to the 2010 Central Chile Earthquake (Mw8.8) that occurred on 06:34:14, 27th of February 2010 (UTC) according to USGS, which is on 15:34:14 of the same day by the Japanese Standard Time (JST). We have developed GPS buoy for detecting tsunami for over 12 years, considering that early detection of tsunami serves for mitigating tsunami disaster. The current GPS buoy is now operational at about 10km west of Cape Muroto, southwest Japan. The Ministry of Land, Infrastructure, Transport and Tourism has implemented the similar system with eleven GPS buoys along the Pacific coast of Japan as a part of the Nationwide Ocean Wave information network for Ports and HArbourS (NOWPHAS) system. All of these GPS buoys are located within 20km from the coast. The 2010 Central Chile earthquake generated significant tsunami. The tsunami travelled across the Pacific Ocean and reached the Japanese coasts in about one day. We present the records of tsunamis that have been registered at these GPS buoys. The presentation tries to compare the records with numerically simulated data. The record of experimental GPS buoy operated nearby Muroto is low-pass filtered with 120seconds of cut-off to segregate the long wave length tsunami from higher frequency wind waves. The effect of tide is also removed from the filtered record. The obtained record is visualized through internet facility (http://www.tsunamigps.com/gpsreal.php). The tsunami due to the Chile earthquake arrived at the GPS buoy at around 3:22PM of 28th February (JST), which is nearly one day after the earthquake. The first peak of tsunami is about 12 centimeter above the mean sea surface height. The second peak arrives about one hour and 46 minutes later with about 20cm height, which is the highest peak among the series of the tsunami waves. The later phases of recognizable tsunami waves continued about one day after the

    The aim of this study was not only to obtain basic technical prerequisites for the establishment of capacity of biological dosimetry at the Ghana Atomic Energy Commission (GAEC) but also to stimulate interest in biological dosimetry research in Ghana and Sub-Saharan Africa. Peripheral blood from four healthy donors was exposed to different doses (0–6 Gy) of gamma rays from a radiotherapy machine and lymphocytes were subsequently stimulated, cultured, and processed according to standard protocols for 48–50 h. Processed cells were analyzed for the frequencies of dicentric and centric ring chromosomes. Radiation dose delivered to the experimental model was verified using GafChromic® EBT films in parallel experiments. Basic technical prerequisites for the establishment of capacity of biological dosimetry in the GAEC have been realized and expertise in the dicentric chromosome assay consolidated. We successfully obtained preliminary cytogenetic data for a dose-response relationship of the irradiated blood lymphocytes. The data strongly indicate the existence of significant linear (α) and quadratic (β) components and are consistent with those published for the production of chromosome aberrations in comparable absorbed dose ranges.

    1991-12-01

    The geographical distribution of Pinus densiflora forests in Japan was examined in relation to the seed germination and seedling establishment information obtained from laboratory experiments, field observations and field experiments. The laboratory experiments indicated that seed germination can occur in all areas of Japan because effective cumulative soil temperatures reaches to 75 °C · day everywhere. However, the field observations and field experiments suggested that seedling establishment is impossible in the northern, eastern and central parts of Hokkaido because the effective cumulative air temperature at a height of 6 cm over bare ground is less than 2 000 °C · day. These results agree approximately with the actual geographical distribution of P. densiflora forest, which can not be found under natural circumstances in these areas.

    In the late 1950s just after the atomic energy research was opened worldwide, there was a lively discussion among scientists on the strategy of nuclear fusion research in Japan. Finally, decision was made that fusion research should be started from the basic, namely, research on plasma physics and from cultivation of human resources at universities under the Ministry of Education, Science and Culture (MOE). However, an endorsement was given that construction of an experimental device for fusion research would be approved sooner or later. Studies on toroidal plasma confinement started at Japan Atomic Energy Research Institute (JAERI) under the Science and Technology Agency (STA) in the mid-1960s. Dualistic fusion research framework in Japan was established. This structure has lasted until now. Fusion research activities over the last 50 years are described by the use of a flowchart, which is convenient to glance the historical development of fusion research in Japan.

    Aggregates of human plasma-derived intravenous immunoglobulins (IVIGs) carries a risk of severe adverse events after nonspecific complement activation induced in humans administrated. Therefore, the anti-complementary activity (ACA) test is legally required in every batch of IVIGs in Japan. However, due to the intrinsic nature of this bioassay, there might be large differences in the results of ACA tests from laboratories, even when the same batch of IVIGs was measured. Our six laboratories evaluated whether there were such differences and argued for establishment of a reference material (RM) for standardization of the ACA test. Our results revealed inter-laboratory differences in ACA values, indicating a need to establish an RM. Therefore, after ACA values in candidate RMs were measured collaboratively, one RM was selected from two candidates and unit value-assigned. The RM in fact normalized the ACA test values for samples measured in parallel at almost all the laboratories, when the values were calculated relative to the assigned unit value of the RM. Thus, we established a first RM to standardize the ACA test in Japan, which enabled each laboratory to normalize ACA values constantly for IVIGs. This indicates that the establishment of an RM can contribute to quality control of IVIGs.

    A total of 22,552 workers employed by the Atomic Weapons Establishment between 1951 and 1982 were followed up for an average of 18.6 years. Of the 3115 who died, 865 (28%) died of cancer. Mortality was 23% lower than the national average for all causes of death and 18% lower for cancer. These low rates were consistent with the findings in other workforces in the nuclear industry and reflect, at least in part, the selection of healthy people to work in the industry and the disproportionate recruitment of people from the higher social classes. At some time during their employment 9389 (42%) of the workers were monitored for exposure to radiation, the average cumulative whole body exposure to external radiation being 7.8 mSv. Their mortality was generally similar to that of other employees, even when exposures were lagged by 10 years. The rate ratio after a 10 year lag in workers with a radiation record compared with other workers was 1.01 (95% confidence interval 0.92 to 1.10) for all causes of death and 1.06 (0.89 to 1.27) for all malignant neoplasms. The only significant differences were for prostatic cancer (rate ratio 2.23; 95% confidence interval 1.13 to 4.40) and for cancers of ill defined and secondary sites (rate ratio 2.37; 1.23 to 4.56). Cancers of lymphatic and haemopoietic tissues were notable for their low occurrence in the study population, with only four deaths from leukaemia and two from multiple myeloma in workers with a radiation record, 9.16 and 3.55 deaths respectively being expected on the basis of national rates. Among workers who had a radiation record 3742 (40%) were also monitored for possible internal exposure to plutonium, 3044 (32%) to uranium, 1562 (17%) to tritium, 638 (7%) to polonium, and 281 (3%) to actinium. In these workers mortality from malignant neoplasms as a whole was not increased, but after a 10 year lag death rates from prostatic and renal cancers were generally more than twice the national average, these excesses arising in

    In 1946 the United States (U.S.) Congress passed the Atomic Energy Act and with it created the Atomic Energy Commission. For the ensuing half-century the AEC and its successors have pursued biological and environmental research with an unwavering mandate to exploit the use of fissionable and radioactive material for medical purposes and, at the same time, to ensure the health of it's workers, the public, and the environment during energy technology development and use (AEC. 1961; DOE 1983; DOE, 1997). The following pages are testimony to the success of this undeviating vision (Figure 1). From the early days of the AEC, cooperation has also linked researchers from the national laboratories, the academic community, and the private sector. The AEC-sponsored research both at national laboratories and universities, and also supported graduate students to develop a cadre of health physicists, radiation biologists, and nuclear engineers. Coordinating these diverse performers has been crucial to the unique teaming that has made many of the successes possible. The success of the biological and environmental research program has often been shared with other federal agencies. The future will demand even stronger and more substantive intraagency, interagency, and international collaborations.

  5. Current status of establishing a venous line in CPA patients by Emergency Life-Saving Technicians in the prehospital setting in Japan and a proposal for intraosseous infusion

    PubMed Central

    2012-01-01

    Introduction It is important to have a venous line in cardiopulmonary arrest (CPA) patients as an emergency treatment measure in prehospital settings, but establishment of a peripheral venous line is difficult in such patients. This study aimed to investigate the current status of intravenous infusion (IVI) in CPA patients by Emergency Life-Saving Technicians (ELSTs) in Japan. We also considered alternative measures in case IVI was difficult or impossible. Methods We investigated a nationwide database between 1 January 2005 and 31 December 2008. From a total of 431,968 CPA cases, we calculated the IVI success rate and related parameters. The Bone Injection Gun (BIG) and simulator legs (adult, pediatric, and infant) were used by 100 ELSTs selected for the study to measure the time required and the success rate for intraosseous infusion (IOI). Results The number of CPA patients, IVI, adrenaline administration, and the IVI success rate in adult CPA patients increased every year. However, the IVI success rate in pediatric CPA patients did not increase. Although adrenaline administration elevated the ROSC rate, there was no improvement in the 1-month survival rate. The time required for IOI with BIG was not different among the leg models. The success rates of IOI with BIG were 93%, 94%, and 84% (p < 0.05 vs. adult and pediatric) in adult, pediatric, and infant models, respectively. Conclusions The rate of success of IVI in adult CPA patients has been increased yearly in Japan. However, as establishing a peripheral venous line in pediatric patients (1-7 years old) by ELSTs is extremely difficult in prehospital settings, there was no increase in the IVI success rate in such patients. As the study findings indicated IOI with BIG was easy and rapid, it may be necessary to consider IOI with BIG as an alternative option in case IVI is difficult or impossible in adult and pediatric patients.

    The aggressive use of such non-fossil energy as the atomic energy with high power density and energy production efficiency is an indispensable choice aiming at the low-carbon society. There is a trial calculation that the carbon dioxide emission of 40000 ton can be suppressed by nuclear power generation by one ton of uranium. The basis of nuclear research after the Second World War in Japan was established by the researchers learnt in Argonne National Laboratory. In 2010, NPPs under operation are 54 units and the total electric generating power is 48.85GW. The amount of nuclear power generation per person of the people is 0.38kW in Japan, and it is near 0.34kW of the United States. However, the TMI accident and the Chernobyl disaster should have greatly stagnated the nuclear industry of Japan although it is not more serious than the United States. A lot of Japanese unconsciously associate a nuclear accident with the atomic bomb. According to the investigation which Science and Technology Agency carried out to the specialist in 1999, ``What will be the field where talent should be emphatically sent in the future?'' the rank of nuclear technology was the lowest in 32 fields. The influence of the nuclear industry stagnation was remarkable in the education. The subject related to the atomic energy of a university existed 19 in 1985 that was the previous year of the Chernobyl disaster decreased to 7 in 2003. In such a situation, we have to rely on the atomic energy because Japan depends for 96% of energy resources on import. The development of the fuel reprocessing and the fast breeder reactor has been continued in spite of a heavy failure. That is the only means left behind for Japan to be released from both fossil fuel and carbon dioxide.

    To establish an accurate atomic mobility database in solder alloys, a reassessment of atomic mobilities in the fcc (face centered cubic) Cu-Ag-Sn system was performed as reported in the present work. The work entailed initial preparation of three fcc Cu-Sn diffusion couples, which were used to determine the composition-dependent interdiffusivities at 873 K, 923 K, and 973 K, to validate the literature data and provide new experimental data at low temperatures. Then, atomic mobilities in three boundary binaries, fcc Cu-Sn, fcc Ag-Sn, and fcc Cu-Ag, were updated based on the data for various experimental diffusivities obtained from the literature and the present work, together with the available thermodynamic database for solder alloys. Finally, based on the large number of interdiffusivities recently measured from the present authors, atomic mobilities in the fcc Cu-Ag-Sn ternary system were carefully evaluated. A comprehensive comparison between various calculated/model-predicted diffusion properties and the experimental data was used to validate the reliability of the obtained atomic mobilities in ternary fcc Cu-Ag-Sn alloys.

  11. Atomic-scale characterization of grain boundaries in strontium titanate: Towards establishing structure-property correlation for interfaces in oxides

    Prabhumirashi, Pradyumna Laxman

    Control over defects at interfaces and the associated potentials barriers represent a collective theme, which is pervasive in a wide variety of devices and structures, crossing multiple disciplines - from basic sciences to engineering to applied technologies. With the rapid emergence of multifunctional oxide systems, the analysis and control of dopants and oxygen defects - especially at interfaces - are the most prominent challenges in realizing next generation devices. In this context, the aberration corrected scanning transmission electron microscopy (STEM) represents truly the next frontier in microscopy, promising atomic level analysis of the defects which control the multifunctional properties of materials and devices. In this thesis, for the first time, a synergistic combination of these two emerging intellectual developments is used. This thesis provides a clear and compelling account of the possibility to manipulate dopant and oxygen defects at the atomic-level in SrTiO3. The core of the thesis is dedicated to atomic scale characterization of Grain Boundary (GB) cores using aberration corrected STEM imaging in conjunction with Electron Energy Loss Spectroscopy (EELS). As a first case study, it is demonstrated that not only is it possible to manipulate the dominating oxygen defects at interfaces to obtain contrasting transport characteristics, but that modern aberration corrected STEM is able to provide a deterministic atomicscale analysis of such defects. It was discovered that the reduced GB is characterized by presence of Ti3+ rich periodic units. The formation of these units is a direct result of electron (left behind by escaping oxygen) localization on Ti atom. The second case study focuses on transition metal (Mn) enriched GBs. It is demonstrated that by reducing the GB, it is possible to manipulate oxygen vacancy concentration as well as variable valence states exhibited by Mn (as Mn2+ and Mn3+).

    Based on the 3D X-ray crystallographic structures of relevant proteins of the malaria parasite involved in invasion to host cells and 3D NMR structures of High Activity Binding Peptides (HABPs) and their respective analogues, it was found that HABPs are rendered into highly immunogenic and sterile immunity inducers in the Aotus experimental model by modifying those amino acids that establish H-bonds with other HABPs or binding to host's cells. This finding adds striking and novel physicochemical principles, at the atomic level, for a logical and rational vaccine development methodology against infectious disease, among them malaria.

    Recent results from steady-state sustainment of high-{beta} plasma experiments in the Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-60U) tokamak [A. Kitsunezaki et al., Fusion Sci. Technol. 42, 179 (2002)] are described. Extension of discharge duration to 65 s (formerly 15 s) has enabled physics research with long time scale. In long-duration high-{beta} research, the normalized beta {beta}{sub N}=2.5, which is comparable to that in the steady-state operation in International Thermonuclear Experimental Reactor (ITER) [R. Aymar, P. Barabaschi, and Y. Shimomura, Plasma Phys. Controlled Fusion 44, 519 (2002)], has been sustained for about 15 s with confinement enhancement factor H{sub 89PL} above 2, where the duration is about 80 times energy confinement time and {approx}10 times current diffusion time ({tau}{sub R}). In the scenario aiming at longer duration with {beta}{sub N}{approx}1.9, which is comparable to that in the ITER standard operation scenario, duration has been extended to 24 s ({approx}15{tau}{sub R}). Also, from the viewpoint of collisionality and Larmor radius of the plasmas, these results are obtained in the ITER-relevant regime with a few times larger than the ITER values. No serious effect of current diffusion on instabilities is observed in the region of {beta}{sub N} < or approx. 2.5, and in fact neoclassical tearing modes (NTMs), which limit the achievable {beta} in the stationary high-{beta}{sub p} H-mode discharges, are suppressed throughout the discharge. In high-{beta} research with the duration of several times {tau}{sub R}, a high-{beta} plasma with {beta}{sub N}{approx}2.9-3 has been sustained for 5-6 s with two scenarios for NTM suppression: (a) NTM avoidance by modification of pressure and current profiles, and (b) NTM stabilization with electron cyclotron current drive (ECCD)/electron cyclotron heating (ECH). NTM stabilization with the second harmonic X-mode ECCD/ECH has been performed, and it is found that EC current

    This paper gives an account of Prof. Dr. Kinji Shimizu, the first president of Nagoya Institute of Technology, and his establishment of Nagoya Municipal Science Museum. After graduating from the Electrical Engineering Department of Kyoto Imperial University in 1923, Shimizu was impressed by the German Museum in Munich during his stay there as a student in 1932. It's the first time that he learned the education in cooperation with industries. Just after the Second World War, he became director general of the Ministry of Education. However, new education system given by the United States focused not on developing practical ability but on gaining the basic knowledge, which is contrary to what he expected. Then, he contributed to the establishment of the Japanese Society for Engineering Education, besides working as the president of Nagoya Institute of Technology in the earlier 1950s. His idea was supported by industries for the economic growth. Throughout his career, Prof. Dr. Shimizu was convinced that practical engineering education would benefit Japan, and wanted to introduce cooperative education between universities and industries, along the lines of the same system in Germany and the United States. With this vision he founded Nagoya Municipal Science Museum in cooperation with local industries and local government as his final achievement. The museum was completed in 1964.

On May 4, 1906, Dr. Shinichiro Asahara, Assistant Professor of the Department of Surgery, was appointed as the first director of the Department of Orthopaedic Surgery, Kyoto Medical School, Kyoto Imperial University. Dr. Michiharu Matsuoka, Assistant Doctor of the Department of Surgery, Tokyo Medical School, Imperial University of Tokyo, was appointed Assistant Professor of Surgery, Kyoto Medical School, Kyoto Imperial University in March 1901. From August 1903 to May 1906, he studied orthopaedic surgery in Germany and returned on May 5, 1906. Dr. Matsuoka was appointed as the director and chief of the Department on May 13, 1906 and took over Dr. Asahara's position. On June 18, 1906, Dr. Matsuoka started his clinic and began giving lectures on orthopaedic surgery. This was the first department of orthopaedic surgery among the Japanese medical schools. Dr. Matsuoka was appointed as Professor in 1907. He had to overcome several obstacles to establish the medical department of a new discipline that had never existed in Japanese medical schools. This article discusses Dr. Matsuoka's contributions to establishing and developing orthopaedic surgery in Japan in the Meiji-era.

    The atomic bombings of Hiroshima and Nagasaki in August 1945 revealed the most destructive power to-date of man-made weapons. Their impact was so great that Japanese scientists thought that a bigger disaster could be prevented only if war was abolished. Thus they welcomed the international control of atomic energy. It was, however, only after the occupation that the Japanese general public began to learn about the horror of these atomic disasters due to the censorship imposed by the occupational forces. The hydrogen bomb test by the US in the Bikini atoll on March 1, 1954 renewed fears of nuclear weapons. The crew of a Japanese fishing vessel, the "Daigo Fukuryu Maru" (Lucky Dragon No. 5) suffered from exposure to radiation from the test. Even after the incident the US did not stop nuclear tests which continued to radioactively contaminate fish and rains in Japan. As a result, the petition movement for the ban of nuclear trials suddenly spread all over the country. By the summer of 1955 the number of the signatures grew to more than one third of Japan's population at the time. Under the strong influence of anti-nuclear Japanese public opinion the Science Council of Japan announced the so-called three principles of atomic energy: "openness," "democracy," and "independence" to ensure atomic energy was used for peaceful uses only. These principles were included in the Atomic Energy Basic Law established in December 1955. With this law, military uses of nuclear energy were strictly forbidden.

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.

    Atom skimmers are devices that act as low-pass velocity filters for atoms in thermal atomic beams. An atom skimmer operating in conjunction with a suitable thermal atomic-beam source (e.g., an oven in which cesium is heated) can serve as a source of slow atoms for a magneto-optical trap or other apparatus in an atomic-physics experiment. Phenomena that are studied in such apparatuses include Bose-Einstein condensation of atomic gases, spectra of trapped atoms, and collisions of slowly moving atoms. An atom skimmer includes a curved, low-thermal-conduction tube that leads from the outlet of a thermal atomic-beam source to the inlet of a magneto-optical trap or other device in which the selected low-velocity atoms are to be used. Permanent rare-earth magnets are placed around the tube in a yoke of high-magnetic-permeability material to establish a quadrupole or octupole magnetic field leading from the source to the trap. The atoms are attracted to the locus of minimum magnetic-field intensity in the middle of the tube, and the gradient of the magnetic field provides centripetal force that guides the atoms around the curve along the axis of the tube. The threshold velocity for guiding is dictated by the gradient of the magnetic field and the radius of curvature of the tube. Atoms moving at lesser velocities are successfully guided; faster atoms strike the tube wall and are lost from the beam.

    Investigator-initiated clinical trials are essential for improving the standard of care for cancer patients, because pharmaceutical companies do not conduct trials that evaluate combination chemotherapy using drugs from different companies, surgery, radiotherapy or multimodal treatments. Government-sponsored cooperative groups have played a vital role in developing cancer therapeutics since the 1950s in the USA; however, the establishment of these groups in Japan did not take place until 30 years later. Methodological standards for multicenter cancer clinical trials were established in the 1980s by the National Cancer Institute and cooperative groups. The Japan Clinical Oncology Group, one of the largest cooperative groups in the country, was instituted in 1990. Its data center and operations office, formed during the 1990s, applied the standard methods of US cooperative groups. At present, the Japan Clinical Oncology Group consists of 14 subgroups, a Data Center, an Operations Office, nine standing committees and an Executive Committee represented by the Japan Clinical Oncology Group Chair. Quality control and quality assurance at the Japan Clinical Oncology Group, including regular central monitoring, statistical methods, interim analyses, adverse event reporting and site visit audit, have complied with international standards. Other cooperative groups have also been established in Japan since the 1980s; however, nobody figures out all of them. A project involving the restructuring of US cooperative groups has been ongoing since 2005. Learning from the success of this project will permit further progress of the cancer clinical trials enterprise in Japan.

    Labidocerachuraumi sp. n. is described from Okinawa, southwestern Japan. The female of the new species differs from other congeners in genital compound somite with right postero-lateral and left antero-lateral processes. The male is distinguished from other congeners by the structure of the fifth leg. This new species is assigned to a newly proposed species group, the Labidoceramadurae species group, within the Labidoceradetruncata species complex. In this species complex five Indo-West Pacific species groups are recognized (cervi, detruncata, gangetica, madurae, and pavo) and defined on the basis of difference in sexual dimorphism.

  5. Establishing the Presence of Coherence in Atomic Fermi Superfluids: Spin-Flip and Spin-Preserving Bragg Scattering at Finite Temperatures

    Guo Hao; Levin, K.; Chien, Chih-Chun

    2010-09-17

    We show how in ultracold Fermi gases the difference between the finite temperature T structure factors, called S{sub -}({omega},q), associated with spin and density, reflects coherent order at all {omega}, q, k{sub F}a, and T. This observation can be exploited in two photon Bragg scattering experiments on gases which are subject to variable attractive interactions. Our calculations incorporate spin and particle number conservation laws which lead to compatibility at general T with two f-sum rules. Because of its generality a measurement of S{sub -}({omega},q) can be a qualitative, direct, in situ approach for establishing superfluid order.

  6. Responding To Changes in the Decommissioning Plans for Demolition of a Former Active Handling Building at The United Kingdom Atomic Energy Establishment Winfrith

    2006-07-01

    The full decommissioning of the former Active Handling Building A59 at Winfrith in Dorset is being carried out by RWE NUKEM Limited under contract from the site owners and nuclear site licence holder, United Kingdom Atomic Energy Authority (UKAEA). Following recent government changes, the United Kingdom's Nuclear Decommissioning Authority (NDA) has now set up contracts with UKAEA for delivery of the site clean-up programme. The building contains two heavily shielded suites of caves originally used to carry out remote examination of irradiated nuclear fuel elements together with other supporting facilities. The original intention was to demolish the caves ahead of the building but after detailed consideration it was concluded that demolition of the building in advance of the caves was more operationally effective. As a result, the original decommissioning plan had to be reworked to reflect these changes. The paper briefly explains how this situation arose and the means by which the problems experienced were overcome by a complete revision to the decommissioning programme. The updated plan has been adopted by UKAEA and work is now proceeding apace to clear the building of redundant items, to complete decontamination of all remaining areas and facilities and to carry out detailed radiological surveys to confirm that the building structure is clean and ready for demolition. Both cave lines have been completely decontaminated to low residual levels of activity and are essentially ready for controlled demolition. This paper describes some of the significant tasks undertaken during the past year with particular reference to the decommissioning techniques that gave the greatest success and the limitations of others originally considered. Some of these processes were aimed at minimising the volume of low level waste (LLW) generated by using standard off-the-shelf equipment to remove contamination from {approx}5 Ton concrete blocks recovered from both cave line structures.

    This report summarizes the status of electronic manufacturing and packaging technology in Japan in comparison to that in the United States, and its impact on competition in electronic manufacturing in general. In addition to electronic manufacturing technologies, the report covers technology and manufacturing infrastructure, electronics manufacturing and assembly, quality assurance and reliability in the Japanese electronics industry, and successful product realization strategies. The panel found that Japan leads the United States in almost every electronics packaging technology. Japan clearly has achieved a strategic advantage in electronics production and process technologies. Panel members believe that Japanese competitors could be leading U.S. firms by as much as a decade in some electronics process technologies. Japan has established this marked competitive advantage in electronics as a consequence of developing low-cost, high-volume consumer products. Japan's infrastructure, and the remarkable cohesiveness of vision and purpose in government and industry, are key factors in the success of Japan's electronics industry. Although Japan will continue to dominate consumer electronics in the foreseeable future, opportunities exist for the United States and other industrial countries to capture an increasingly large part of the market. The JTEC panel has identified no insurmountable barriers that would prevent the United States from regaining a significant share of the consumer electronics market; in fact, there is ample evidence that the United States needs to aggressively pursue high-volume, low-cost electronic assembly, because it is a critical path leading to high-performance electronic systems.

    A new strategic energy plan decided by the Japanese Cabinet in 2014 strongly supports the steady promotion of nuclear fusion development activities, including the ITER project and the Broader Approach activities from the long-term viewpoint. Atomic Energy Commission (AEC) in Japan formulated the Third Phase Basic Program so as to promote an experimental fusion reactor project. In 2005 AEC has reviewed this Program, and discussed on selection and concentration among many projects of fusion reactor development. In addition to the promotion of ITER project, advanced tokamak research by JT-60SA, helical plasma experiment by LHD, FIREX project in laser fusion research and fusion engineering by IFMIF were highly prioritized. Although the basic concept is quite different between tokamak, helical and laser fusion researches, there exist a lot of common features such as plasma physics on 3-D magnetic geometry, high power heat load on plasma facing component and so on. Therefore, a synergetic scenario on fusion reactor development among various plasma confinement concepts would be important.

    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.

    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.

    Japan has a complex social security system. This article discusses the demographic and economic situation in Japan as background for understanding the setting in which the social security system functions. Japan has a three-pillar system for retirement income. The first pillar is the social security pension plan; the second pillar is the voluntary occupational pension plan; and the third pillar is personal savings, including the personal pension plan. The most important part of the retirement income system is the social security pension plan, which paid benefits accounting for 64% of the total income of elderly households in 1998. The five Employees' Pension Plans are established on a compulsory social insurance basis. Most large Japanese employers have a mandatory retirement age. Over 90% of all employees, including public sector ones, must retire from their career jobs at age 60.

    This study was conducted to examine the association between marital adjustment and psychological distress in a large, probability sample of married adults in Japan (N = 710) from the Midlife Development in Japan (MIDJA) study. Results indicate that positive and negative dimensions of marital adjustment were significantly associated with dimensional and categorical measures of psychological distress. Furthermore, the associations between marital adjustment and psychological distress remained significant when statistically controlling for neuroticism, quality of friend and family relationships, and demographic variables. These results demonstrate that the well-established association between marital adjustment and psychological distress found in European-American countries is also found in Japan. Findings support continued research on marital functioning and psychological distress in East Asian countries.

    1993-01-01

    The first two books on behavior analysis (Skinner, 1938; Keller & Schoenfeld, 1950) had chapter-length coverage of motivation. The next generation of texts also had chapters on the topic, but by the late 1960s it was no longer being given much treatment in the behavior-analytic literature. The present failure to deal with the topic leaves a gap in our understanding of operant functional relations. A partial solution is to reintroduce the concept of the establishing operation, defined as an environmental event, operation, or stimulus condition that affects an organism by momentarily altering (a) the reinforcing effectiveness of other events and (b) the frequency of occurrence of that part of the organism's repertoire relevant to those events as consequences. Discriminative and motivative variables can be distinguished as follows: The former are related to the differential availability of an effective form of reinforcement given a particular type of behavior; the latter are related to the differential reinforcing effectiveness of environmental events. An important distinction can also be made between unconditioned establishing operations (UEOs), such as food deprivation and painful stimulation, and conditioned establishing operations (CEOs) that depend on the learning history of the organism. One type of CEO is a stimulus that has simply been paired with a UEO and as a result may take on some of the motivative properties of that UEO. The warning stimulus in avoidance procedures is another important type of CEO referred to as reflexive because it establishes its own termination as a form of reinforcement and evokes the behavior that has accomplished such termination. Another CEO is closely related to the concept of conditional conditioned reinforcement and is referred to as a transitive CEO, because it establishes some other stimulus as a form of effective reinforcement and evokes the behavior that has produced that other stimulus.

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.

    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.

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 atomic dipole polarizability governs the first-order response of an atom to an applied electric field. Atomic polarization phenomena impinge upon a number of areas and processes in physics and have been the subject of considerable interest and heightened importance in recent years. In this paper, we will summarize some of the recent applications of atomic polarizability studies. A summary of results for polarizabilities of noble gases, monovalent, and divalent atoms is given. The development of the CI+all-order method that combines configuration interaction and linearized coupled-cluster approaches is discussed.

    2015-02-01

    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.

  10. Water reuse in Japan.

    2001-01-01

    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 in scientific ballooning in Japan during 1998-1999 are reported. The total number of scientific balloons flown in Japan in 1998 and 1999 was sixteen, eight flights in each year. The scientific objectives were observations of high energy cosmic electrons, air samplings at various altitudes, monitoring of atmospheric ozone density, Galactic infrared observations, and test flights of new type balloons. Balloon expeditions were conducted in Antarctica by the National Institute of Polar Research, in Russia, in Canada and in India in collaboration with foreign countries' institutes to investigate cosmic rays, Galactic infrared radiation, and Earth's atmosphere. There were three flights in Antarctica, four flights in Russia, three flights in Canada and two flights in India. Four test balloons were flown for balloon technology, which included pumpkin-type super-pressure balloon and a balloon made with ultra-thin polyethylene film of 3.4 μm thickness.

    1998-01-01

    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.

    The Science Council of Japan (SCJ) is an academic body that represents Japanese 700,000 scientists. The activity of SCJ is changing rapidly, in which the science associated with society is increasingly important. In this context, the engineering education for ethics is treated at SCJ. The importance of engineering ethics was first recognized at the 5th division of 17th term (1999-2001) of SCJ, in which education for engineering ethics based on the analysis of ethical problems occurred in Japan is recommended and it asked the engineering societies to establish the code of ethics. Following this proposal, SCJ founded a committee to treat the problem at 18th and 19th terms. The committee proposed a procedure to prevent misconduct associated with scientific activities and the importance of education of science and engineering ethics especially for young students at tertiary education.

    2013-01-01

    To investigate the migration of anthropogenic 129I in the environment, we measured 129I concentrations at both subarctic (above 40oN) and subtropical (below 40oN) circulations in the surface seawater of the Japan Sea. The averaged concentrations of stations 193, 194, 201, 206 and 210 above 200 m were (2.1 ± 0.3) × 1010 atoms/m3, (2.0 ± 0.2) × 1010 atoms/m3, (1.6 ± 0.3) × 1010 atoms/m3, (1.4 ± 0.3) × 1010 atoms/m3 and (1.7 ± 0.3) × 1010 atoms/m3, respectively. The averaged concentration at the subarctic circulation in the Japan Sea above 200 m (1.9 × 1010 atoms/m3) was higher than that in the subtropical circulation (1.5 × 1010 atoms/m3). This latitudinal distribution pattern of 129I is not consistent with those of bomb-derived radionuclides such as 14C, 90Sr and 137Cs. Taking into account latitudinal location and the total amount of releases from reprocessing plants, this discriminating latitudinal distribution of 129I in the Japan Sea would indicate that a significant amount of 129I originating from active reprocessing plants in Europe is supplied to the surface of the Japan Sea.

    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.

    2013-02-01

    Systematic studies of cosmic rays in Japan were started when the Nishina Laboratory was established in Riken in 1931, after Nishina came back from the Niels Bohr Institute in Copenhagen. He was already known as an author of Klein-Nishina formula. He spent a great deal of effort to spread modern physics in Japan, inviting Dirac and Heisenberg to give series of lectures at the university of Tokyo, which later established the strong group of theoretical physicists including Yukawa, Tomonaga, Sakata and others. He also spent a great deal of effort in comprehensive studies of cosmic-rays including the precise measurements of the mass of mesons, of the intensity at the deepest underground of 3000 m.w.e., and of other research to be discussed. It is to be noted that the encouragement by the theoretical group of Yukawa, Tomonaga and others stimulated the recovery of the research after World War II in Japan.

    Feng, Q; Suzuki, Y; Hisashige, A

    1998-01-01

    The authors used gold-amalgamation cold-vapor atomic absorption spectrometry and ECD-gas chromatography to analyze total mercury and methylmercury levels in hair samples obtained from 362 residents in Harbin, China; Medan, Indonesia; and Tokushima, Japan. In this study, the authors initially questioned whether mercury levels in hair differed among different study areas, and if there were differences, they questioned the contributing factors. In the three countries surveyed, total mercury and methylmercury levels in hair were lowest in residents of China and were highest in residents of Japan. In the district of Tokushima, Japan, total mercury and methylmercury levels were highest in the coastal district, followed by the middle district; the lowest levels occurred in the mountainous district. In Japan, an individual's total mercury level correlated very closely with that person's methylmercury level; in China and Indonesia, the correlation between these 2 parameters was low. No subjects in China or Indonesia had high levels of methylmercury in hair; this was true even if their total mercury levels were high. This finding suggests that the high total mercury levels observed in some residents of China and Indonesia reflected exposure to inorganic mercury. In Japan, mercury (especially methylmercury) levels in hair samples were quite high. Fish and shellfish, caught in seas uncontaminated by human activity, appeared to be major sources of the high levels of hair mercury in Japanese subjects.

  8. Current affairs in earthquake prediction in Japan

    NASA Astrophysics Data System (ADS)

    Uyeda, Seiya

    2015-12-01

    As of mid-2014, the main organizations of the earthquake (EQ hereafter) prediction program, including the Seismological Society of Japan (SSJ), the MEXT Headquarters for EQ Research Promotion, hold the official position that they neither can nor want to make any short-term prediction. It is an extraordinary stance of responsible authorities when the nation, after the devastating 2011 M9 Tohoku EQ, most urgently needs whatever information that may exist on forthcoming EQs. Japan's national project for EQ prediction started in 1965, but it has made no success. The main reason for no success is the failure to capture precursors. After the 1995 Kobe disaster, the project decided to give up short-term prediction and this stance has been further fortified by the 2011 M9 Tohoku Mega-quake. This paper tries to explain how this situation came about and suggest that it may in fact be a legitimate one which should have come a long time ago. Actually, substantial positive changes are taking place now. Some promising signs are arising even from cooperation of researchers with private sectors and there is a move to establish an "EQ Prediction Society of Japan". From now on, maintaining the high scientific standards in EQ prediction will be of crucial importance.

  9. Strong Quake Strikes Japan

    As Eos was about to go to press, a powerful earthquake with a preliminary estimated magnitude of 8.9 shook the northeast coast of Japan on 11 March at 05:46:23 UTC. It is the largest known earthquake along the Japan Trench subduction zone since 869 A.D. or earlier, Brian Atwater, geologist with the U.S. Geological Survey (USGS), told Eos. The quake's magnitude would place it fifth in terms of any earthquake magnitude worldwide since at least 1900, according to information from the USGS Earthquake Hazards Program. The amount of energy released in the quake—which occurred 130 kilometers east of Sendai, Honshu, at a depth of 24.4 kilometers—was equivalent to the energy from 30 earthquakes the size of the 1906 quake in San Francisco, Calif., according to David Applegate, USGS senior science advisor for earthquake and geologic hazards. He said the economic losses from the shaking are estimated to be in the tens of billions of dollars.

  10. Nutrition trends in Japan.

    PubMed

    Matsumura, Y

    2001-01-01

    The National Nutrition Survey (NNS) in Japan has been undertaken annually since 1946. It was originally intended to provide information on the food and nutrient intake of the Japanese people, with a view to acquiring emergency food supplies from other countries when food shortages caused malnutrition in many Japanese. The food balance sheet (FBS) has been drawn up since 1949 to show the food supply available to the Japanese people. The trends and figures shown by both approaches were similar until the mid-1970s. Since then, however, the disparity between the food supply and the intake of foods and nutrients has been getting larger. National food security means that a country has enough food for everyone. This does not mean, however, that every family has enough food, because the food may not be evenly distributed. In fact, marginal deficiencies in iron and calcium are thought to still exist and there is considerable variation among households in energy intake. In Japan, nutrition and diet are now considered to play important roles in the emerging problems of obesity, diabetes mellitus, hypertension etc., because of excessive energy intake and deficiency or excessive intake of certain nutrients.

  11. Ski slope vegetation in central Honshu, Japan

    Tsuyuzaki, Shiro

    1995-09-01

    To determine the status of the vegetation of ski slopes in northeastern-central Honshu, Japan, 94 plots (2×2 m) were set up on five ski areas (101-520 m elevation) which were established between 1945 and 1985 by forest clear-cutting, land modification, and seeding. Six vegetation types were recognized: five grasslands dominated by Digitaria adscendens, Miscanthus sinensis, Zoysia japonica, Festuca rubra, and Pteridium aquilinum var. latiusculum, respectively, and bare areas of very low to no vegetation cover. Of the dominant species, F. rubra is the only introduced species; it does not, however, appear to persist. After the introduced grassland declines M. sinensis or annual grasslands develop. Native plants, especially woody species, can establish in M. sinensis grassland but do not establish in the other grasslands. It is concluded that the introduction of exotic species is inappropriate to maintain ski slope vegetation, and the development of M. sinensis grassland is desirable to promote natural revegetation.

    1985-01-01

    The primary objective was the obtainment of atomization and mixing performance data for a variety of typical liquid oxygen/hydrocarbon injector element designs. Such data are required to establish injector design criteria and to provide critical inputs to liquid rocket engine combustor performance and stability analysis, and computational codes and methods. Deficiencies and problems with the atomization test equipment were identified, and action initiated to resolve them. Test results of the gas/liquid mixing tests indicated that an assessment of test methods was required. A series of 71 liquid/liquid tests were performed.

    Minamata disease is alkylmercury poisoning causing Hunter-Russell syndrome due to ingestion of seafood polluted by industrial waste. Two epidemics occurred in Minamata (1956) and Niigata (1965), Japan. Many infants with "cerebral palsy" in villages where adult cases occurred were established as having congenital Minamata disease. Developing brains were affected by alkylmercury through transplacental exposure and even by breastfeeding. This report reviews the history, clinical features, pathology, epidemiology, metal analysis, experiments, and sociolegal aspects of congenital Minamata disease. Many victims are still alive and their present conditions are reviewed.

  17. Doping of Semiconducting Atomic Chains

    NASA Technical Reports Server (NTRS)

    Toshishige, Yamada; Kutler, Paul (Technical Monitor)

    1997-01-01

    Due to the rapid progress in atom manipulation technology, atomic chain electronics would not be a dream, where foreign atoms are placed on a substrate to form a chain, and its electronic properties are designed by controlling the lattice constant d. It has been shown theoretically that a Si atomic chain is metallic regardless of d and that a Mg atomic chain is semiconducting or insulating with a band gap modified with d. For electronic applications, it is essential to establish a method to dope a semiconducting chain, which is to control the Fermi energy position without altering the original band structure. If we replace some of the chain atoms with dopant atoms randomly, the electrons will see random potential along the chain and will be localized strongly in space (Anderson localization). However, if we replace periodically, although the electrons can spread over the chain, there will generally appear new bands and band gaps reflecting the new periodicity of dopant atoms. This will change the original band structure significantly. In order to overcome this dilemma, we may place a dopant atom beside the chain at every N lattice periods (N > 1). Because of the periodic arrangement of dopant atoms, we can avoid the unwanted Anderson localization. Moreover, since the dopant atoms do not constitute the chain, the overlap interaction between them is minimized, and the band structure modification can be made smallest. Some tight-binding results will be discussed to demonstrate the present idea.

    The mummy of priest Kochi (preserved at Saishoji Temple, Teradomari, Niigata Pref.) has become famous, since it appeared in the book "Snow Country Tales" written by Bokushi Suzuki in 1841 (Fig. 1). In a country of high humidity, such as Japan, the belief that mummification could not, and did not, exist would not be altogether unfounded, but rather more a matter of common sense. There are two dozen Buddhist mummies in this country. It was not known until 1961 that a reliable source of artificial mummification has existed in Japan. The Japanese Buddhist mummies, apart from those of the Fujiwara family, a powerful clan of northeast Japan in the 12th century, dated mostly from the 17th to the 19th century as given in Table 1. Three principal types of mummification described by Vreeland, Jr. and Cockburn (1980) could be identified in the Japanese Buddhist mummies: type I, natural mummification; type II, intentional natural; and type III, artificial. Matsumoto (1990) classified the mummies into four groups, based on their ideological backgrounds: group A, mummies of the priests having faith in the Amitabha (the Supreme Buddha presiding over the Pure Land in the West); group B, sokushin-butsu mummies of the priests belonging to the Shingon sect of Japanese Buddhism founded by Kukai (Kobo-daishi); group C, nyujo mummies of the priests having faith in the Maitreya (the Buddha presiding over the Pure Land in the North, or the Buddha of the future); and group D, other mummies. These mummies of groups A, B, C and D are respectively listed in Table 2. Previous papers have shown that the mummies of the groups A, C and D belonged to the mummification of type I (natural mummification) or type II (intentional natural), whereas those of only the group B were of type III (artificial). The mummies of groups A to D were given as follows. a) Mummies of group A. The four mummies of the Fujiwara family in the Amitabha faith (preserved at Chusonji Temple, Hiraizumi, Iwate Pref.), which

    The concept of immunization was started in Japan in 1849 when Jenner's cowpox vaccine seed was introduced, and the current immunization law was stipulated in 1948. There have been two turning points for amendments to the immunization law: the compensation remedy for vaccine-associated adverse events in 1976, and the concept of private vaccination in 1994. In 1992, the regional Court of Tokyo, not the Supreme Court, decided the governmental responsibility on vaccine-associated adverse events, which caused the stagnation of vaccine development. In 2010, many universal vaccines became available as the recommended vaccines, but several vaccines, including mumps, zoster, hepatitis B, and rota vaccines, are still voluntary vaccines, not universal routine applications. In this report, immunization strategies and vaccine development are reviewed for each vaccine item and future vaccine concerns are discussed.

    Before World War II, weather forecasters had little knowledge of upper-air wind patterns above 20000 feet. Data were seldom avai able at these heights, and the need was not great because commercial aircraft seldom flew at these altitudes. The war in the Pacific changed all that. Wind forecasts for 30000 feet plus became urgent to support the XXI Bomber Command in its bombing mission over Japan.The U.S. Army Air Force Pacific Ocean Area (AAFPOA) placed a Weather Central in the Marianas Islands in 1944 (Saipan in 1944 and Guam in 1945) to provide forecasting support for this mission. A forecasting procedure was put into operation that combined the elements known as "single-station forecasting" and an advanced procedure that used "altirmeter corrections" to analyze upper-airdata and make prognoses. Upper-air charts were drawn for constant pressure surfaces rather than constant height surfaces. The constant pressure surfaces were tied together by means of the atmospheric temperature field represented by specific temperature anomalies between pressure surfaces. Wind forecasts over the Marianas-Japan route made use of space cross sections that provided the data to forecast winds at each 5000-ft level to 35000 ft along the mission flight path. The new procedures allowed the forecaster to construct internally consistent meteorological charts in three dimensions in regions of sparse data.Army air force pilots and their crews from the Marianas were among the first to experience the extreme wind conditions now known as the "jet stream". Air force forecasters demonstrated that, with experience, such winds could reasonably be forecast under difficult operational conditions.

    Japan, a country generally successful in solving population problems, now faces the problem of an aging population. It must provide welfare for its aged population and give them a role in society. Recognizing the vital importance to economic and social development of population problems in developing countries, Japan has cooperated through bilateral and multilateral channels in assisting various projects of developing countries concerned about population problems. As for bilateral aid, Japan extends technical cooperation to Economic and Social Commission for Asia and the Pacific (ESCAP) region countries by providing them with experts, by conducting surveys, by giving equipment, and by organizing training courses, particularly in the field of family planning. Japan also cooperates with some of the developing countries of the ESCAP region by providing them with financial assistance in the form of multilateral cooperation. Japan makes a cash contribution the the UN Fund for Population Activities (UNFPA) as the biggest donor country. In fiscal year 1984, the Japanese contribution to UNFPA totaled $US 40.1 million; the contribution will amount of $US 42.9 million in 1985. Aware of the importance of human resource development in the field of population, Japan has organized annual group training courses for the developing countries, namely: the Seminar on Family Planning Administration for Senior Officers; the Seminar on Community-Based Family Planning Strategy; and the Seminar on Health Aspects of Family Planning. Japan generally supports the work of ESCAP with regard to training in the field of population.

    In this article, we describe the history and current state of psychosomatic medicine (PSM) in Japan and propose measures that could be considered based on our view of the future prospects of PSM in Japan. The Japanese Society of PSM (JSPM) was established in 1959, and the first Department of Psychosomatic Internal Medicine in Japan was established at Kyushu University In 1963. PSM in Japan has shown a prominent, unique development, with 3,300 members (as of March 2016), comprised of 71.6% of medical doctors including psychosomatic internal medicine (PIM) specialists, general internists, psychiatrists, pediatricians, obstetricians and gynecologists, dentists, dermatologists, and others. Most of the non-physician members include psychology and nursing staff specialists. The Japanese Society of Psychosomatic Internal Medicine (JSPIM), founded in 1996, is another major society with more than 1,200 physicians that is mainly composed of internists. The first joint congress of the five major PSM societies from each field was held in 2009. They included the Japanese Society of Psychosomatic Medicine, Psychosomatic Obstetrics and Gynecology, Psychosomatic Pediatric Medicine, Psychosomatic Dental Medicine, and Psychosomatic Internal Medicine. Several subdivided societies in related medical fields have also been established for cardiovascular, digestive, dermatological, and oriental medicine and for eating disorders, pain, fibromyalgia, stress science, behavioral medicine, and psycho-oncology. JSPM and JSPIM participate in international activities including publishing BioPsychoSocial Medicine (BPSM) and the establishment of a sister society relationship with the Germany College of PSM. PSM in Japan has adopted a variety of professional psychotherapies, including transactional analysis, autogenic therapy, and cognitive behavioral therapy. Mutual interrelationship has been promoted by the Japanese Union of Associations for Psycho-medical Therapy (UPM). Although PSM in Japan is

    The aim of this study was to determine whether the features of multiple personality disorder (MPD) in Japan are similar to those in North America, although a wide disparity exists in the prevalence of MPD between the two areas. In order to describe the features of MPD in Japan, we obtained clinical data from MPD case reports, including two of our own cases, published in Japanese academic journals and compared it with the data from other countries. The cases in Japan differed significantly from those in North America in the mean number of personalities and prevalence of sexual and/or physical abuse.

    Work performed by the University of Alabama in Huntsville's (UAH) Center for Applied Optics (CAO) entitled Atomic Research is documented. Atomic oxygen (AO) effects on materials have long been a critical concern in designing spacecraft to withstand exposure to the Low Earth Orbit (LEO) environment. The objective of this research effort was to provide technical expertise in the design of instrumentation and experimental techniques for analyzing materials exposed to atomic oxygen in accelerated testing at NASA/MSFC. Such testing was required to answer fundamental questions concerning Space Station Freedom (SSF) candidate materials and materials exposed to atomic oxygen aboard the Long-Duration Exposure Facility (LDEF). The primary UAH task was to provide technical design, review, and analysis to MSFC in the development of a state-of-the-art 5eV atomic oxygen beam facility required to simulate the RAM-induced low earth orbit (LEO) AO environment. This development was to be accomplished primarily at NASA/MSFC. In support of this task, contamination effects and ultraviolet (UV) simulation testing was also to be carried out using NASA/MSFC facilities. Any materials analysis of LDEF samples was to be accomplished at UAH.

    The evolution of methods to assess genotoxicity of test compounds is thought to be one of the important subjects in The Japanese Environmental and Mutagen Society (JEMS). In 1970, the Ministry of Education of Japan (at that time) organized a research group (Organizer: Y. Tazima, National Institute of Genetics), and started a systematic research on the genotoxic effects induced by chemical substances. Considering the importance of this issue through the outcomes of the research group, JEMS was established in 1972, and President Tazima organized the 1st annual meeting in the August in Tokyo with the participation of experts in this field working in national institutes, universities and others in Japan. The discovery that food additives possessed genotoxic potential triggered various scientific activities in the field of genotoxicity. Another important point was the correlation between genotoxicity and carcinogenicity, in which the establishment of the reverse mutation assay played an important role. Other critical factors, such as side effects of drugs, occupational cancer, and environmental pollution due to genotoxic chemicals, emphasized the importance of genotoxicity tests for human safety. The tests performed to assess genotoxicity from 1960s to 1980s will be described to understand that many different genotoxic methodologies were discussed in these periods.

    With the definition of teratogenicity expanded in terms of the developmental stages when an agent acts and the types of developmental anomalies induced, the concept of developmental toxicity has been established. The examination of functional developmental disorders including behavior has become one of the most important items for the evaluation of developmental toxicity of chemicals, especially pharmaceutical drugs. The guidelines for developmental toxicity testing of drugs in Japan stress the need for examination of growth and development including behavior and fertility on the postweaning offspring. The outline of the Japanese guidelines is presented and it is emphasized that studies should be done as research and include self evaluation of the scientific truth of the experiment and extrapolation to humans. In addition, the activities of the Behavioral Teratology Meeting, a satellite meeting to the Japanese Teratology Society, are introduced and enquete surveys of the Japan Pharmaceutical Manufacturers Association and collaborative studies for the standardization of learning tests in Japan are briefly presented.

    Genotypes are associated with the natural course of hepatitis C virus (HCV) infection and response to antiviral therapy for HCV. HCV genotype 1b has been the dominant genotype in Japan, where the prevention of HCV transmission through blood transfusion or nosocomial infection has been established since 1990. The distribution of HCV genotype was investigated based on patient's birth year in 5515 HCV-infected Japanese individuals at three institutions from different areas of Japan. At all three institutions, the proportion of HCV genotype 1b decreased and was <50% in individuals born after 1970. By contrast, the percentage of HCV genotype 2b increased in subsequent birth cohorts after 1920-1929. Significant changes in HCV genotype distribution were observed across Japan regardless of area.

    Recent research by Chinese and Japanese historians of psychology and education suggests that it was educational reformers' copying of Japan's education system in the 1st decade of the 20th century that provided the context for developing modern psychology in China. Psychology, although not well understood by those reformers, was thought to be useful in teacher training. In 1902 Japanese psychology teachers came to China and some textbooks were translated. Chinese students studying in Japan also brought back psychological knowledge in translations. However, the Chinese attraction to study in Japan declined after 1906. As the United States opened new universities and provided opportunities for Chinese students to study in U.S. schools, it became a more attractive option for later generations of Chinese, who saw psychology become established as a separate discipline.

    Offshore wind energy has been widely exploited in Europe. Having a long coastline, the offshore wind energy will be the one of the important solutions for the increase of renewable energy in Japan. However, due to the difference in wind and marine condition between Japan and Europe, the safety, the environmental impact and the economical feasibility of the offshore wind power generation system have to be investigated in Japan. According to the data observed offshore, the wind speed is enough higher than that on land and the wind energy is economically feasible. In order to utilize the energy, the design method of the foundation against very high waves in typhoon storm should be established. For shallow offshore coastal area, gravity foundation type has been improved by hydraulic experiment. Additionally, for deeper ocean, floating types such as semi-submersible float and spar-buoy have been researched.

    Shortages of direct care workers have been of concern both in the United States and in Japan. This article compares issues surrounding long-term care provisions in the two countries and introduces Japan's unique licensure and certificate system for direct care workers. Japan has established three levels of direct care worker certificates and a direct care licensure, which can be potentially used as a career ladder. Studies show that this system has resulted in different work conditions and benefits between different certificate and licensure levels but had a limited impact on hourly wage and task differentiation. Implications for the United States are also discussed.

    Obtaining Pu background data in the environment is essential for contamination source identification and assessment of environmental impact of Pu released from the Fukushima Daiichi nuclear power plant (FDNPP) accident. However, no baseline information on Pu isotopes in Fukushima Prefecture has been reported. Here we analyzed 80 surface soil samples collected from the central-eastern Japan during 1969-1977 for (239+240)Pu activity concentration and (240)Pu/(239)Pu atom ratio to establish the baseline before the FDNPP accident. We found that (239+240)Pu activity concentrations ranged from 0.004 -1.46 mBq g(-1), and (240)Pu/(239)Pu atom ratios varied narrowly from 0.148 to 0.229 with a mean of 0.186 ± 0.015. We also reconstructed the surface deposition density of (241)Pu using the (241)Pu/(239)Pu atom ratio in the Japanese fallout reference material. The obtained results indicated that, for the FDNPP-accident released (241)Pu, a similar radiation impact can be estimated as was seen for the global fallout deposited (241)Pu in the last decades.

    A simple theory for establishing the stability or instability of positron-atomic systems against dissociation is presented. The theory consists of assuming that Morse-potential parameters for protonic diatoms are transferrable to the corresponding positronic molecules, and making appropriate reduced-mass modifications in the calculation of binding energies. The surprisingly good reliability of the method is established by appealing to the well-known positronium affinities of atomic hydrogen and fluorine. Positronium (Ps) binding is found for about half of the 42 atoms tested. In addition, instability is indicated for all nine positron-atom systems tested, and stability is indicated for seven of eight negatively charged systems tested; e.g., PsO/sup -/.

Its activities include publishing reference books and electronic teaching materials for primary school teachers and students, conducting surveys on the people's consciousness on the ocean, and supporting the events such as 'Ocean Science Cafe' for the public, oceanographer's talks in class room and sea side, and seminars on board of research vessel for high-school teachers and students. Its activities are announced to the public in its website and through Twitter. The records are available to the public in the websites. Some JOS members including me are telling the public the basic knowledge of ocean science, additional explanations to scientific topics in mass media, their thoughts on the ocean, the science, and STEM education, and their daily life such as travels, meetings and cruises through their own private websites, blogs, and accounts in Twitter and Facebook. In this presentation, as a coordinator of the 'Ocean Science Cafe', I will indicate how well it has worked as a good method for promoting mutual communication between non-professional citizens and oceanographers, and changed a scientist to a better citizen. Also, as an ocean science blogger, I will mention a good effect of the mutual communication with the public from my experience. It is concluded that the science communication by new media should not be one-way but really two-way to understand well what people wish to know and have difficulties to understand, and where they stop learning.

    The successful implementation of a strategy to produce high-definition systems within the Japanese economy will favorably affect the fundamental competitiveness of Japan relative to the rest of the world. The development of an infrastructure necessary to support high-definition products and systems in that country involves major commitments of engineering resources, plants and equipment, educational programs and funding. The results of these efforts appear to affect virtually every aspect of the Japanese industrial complex. The results of assessments of the current progress of Japan toward the development of high-definition products and systems are presented. The assessments are based on the findings of a panel of U.S. experts made up of individuals from U.S. academia and industry, and derived from a study of the Japanese literature combined with visits to the primary relevant industrial laboratories and development agencies in Japan. Specific coverage includes an evaluation of progress in R&D for high-definition television (HDTV) displays that are evolving in Japan; high-definition standards and equipment development; Japanese intentions for the use of HDTV; economic evaluation of Japan's public policy initiatives in support of high-definition systems; management analysis of Japan's strategy of leverage with respect to high-definition products and systems.

  9. [Canine histoplasmosis in Japan].

    PubMed

    Sano, Ayako; Miyaji, Makoto

    2003-01-01

    Histoplasmosis is a fungal infection caused by Histoplasma capsulatum and is distributed a worldwide. Although the disease has been treated as an imported mycosis, some autochthonous human, 1 equine and 4 canine cases suggested that the disease is endemic. Histoplasmosis is classified depending on the variety of causative agent. Histoplasmosis farciminosi known as pseudofarcy, is manifested only in Perissodactyla where it invades lymph nodes and lymph ducts, and is recognized by isolation from horses. Historically, Japan was one of the endemic areas of pseudofarcy before World War II, and more than 20,000 cases were recorded in horses used by the military. Interestingly, Japanese canine histoplasmosis uniformly showed skin ulcers and granulomatous lesions on the skin without pulmonary or gastrointestinal involvement, both of which were very similar to pseudofarcy. It was diagnosed as histoplasmosis by the detection of internal transcribed spacer legions of rRNA gene of H. capsulatum from paraffin embedded tissue samples. Furthermore, the fungal isolate from the human case with no history of going abroad or immigrating was identified as H. capsulatum var. farciminosum by a gene sequence. These facts indicated that pseudofarcy is not only an infectious disease in horses, but also a zoonotic fungal infection. Japanese autochthonous canine histoplasmosis might be a heteroecism of pseudofarcy because of its likeness to the human case, the similarity of clinical manifestations and the historical background at this stage.

  10. 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.

    The International Symposium on Atomic Technology (ISAT) is held every year. The Third Symposium (ISAT-3) was held on 5-6 March 2009 at the Tokyo International Exchange Center, Tokyo, Japan jointed with the Third Polyscale Technology Workshop (PTW-3). The ISAT-3 symposium was intended to offer a forum for the discussion of the latest progress in atomic technologies, which was successively held after ISAT-1 at Tsukuba and ISAT-2 at Awaji in 2007. The symposium was attended by 136 participants. There were 12 invited and 4 oral presentations. The number of poster presentations was 101. From all the contributions, 32 papers selected through review process are contained in this volume. The 'Atomic Technology Project' and the 'Polyscale Technology Project' were started in 2006 as the joint project of three institutions; (1) Center for Atomic and Molecular Technologies, Graduate School of Engineering, Osaka University (CAMT), (2) Tsukuba Research Center for Interdisciplinary Materials Science, Graduate School of Pure and Applied Sciences, University of Tsukuba (TIMS) and (3) Polyscale Technology Research Center, Research Institute for Science and Technology, Tokyo University of Science (PTRC), each of which were independently pursuing atomic and polyscale technologies. The project is funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan. The goal of these projects is to contribute to the development of atomic and polyscale science and technologies. In this symposium, four research fields were focused on: Biomedical Applications, Fabrication for Advanced Materials and Devices, Magnetic Applications, and Quantum and Molecular Engineering for Advanced Technologies.

    On Japan, wintertime cold wave has social, economic, psychological and political impacts because of the lack of atomic power stations in the era of post Fukushima world. The colder winter is the more electricity is needed. Wintertime weather of Japan and its prediction has come under the world spotlight. The winter of 2012/13 in Japan was abnormally cold, and such a cold winter has persisted for 3 years. Wintertime climate of Japan is governed by some dominant modes of the large-scale atmospheric circulations. Yasunaka and Hanawa (2008) demonstrated that the two dominant modes - Arctic Oscillation (AO) and Western Pacific (WP) pattern - account for about 65% of the interannual variation of the wintertime mean surface air temperature of Japan. A negative AO brings about cold winter in Japan. In addition, a negative WP also brings about cold winter in Japan. Looking back to the winter of 2012/13, both the negative AO and negative WP continued from October through December. If the previous studies were correct, it would have been extremely very cold from October through December. In fact, in December, in accordance with previous studies, it was colder than normal. Contrary to the expectation, in October and November, it was, however, warmer than normal. This discrepancy signifies that an additional hidden circumstance that heats Japan overwhelms these large-scale atmospheric circulations that cool Japan. In this study, we therefore seek an additional cause of wintertime climate of Japan particularly focusing 2012 as well as the AO and WP. We found that anomalously warm oceanic temperature surrounding Japan overwhelmed influences of the AO or WP. Unlike the inland climate, the island climate can be strongly influenced by surrounding ocean temperature, suggesting that large-scale atmospheric patterns alone do not determine the climate of islands.

    Thyroid storm is an endocrine emergency which is characterized by multiple organ failure due to severe thyrotoxicosis, often associated with triggering illnesses. Early suspicion, prompt diagnosis and intensive treatment will improve survival in thyroid storm patients. Because of its rarity and high mortality, prospective intervention studies for the treatment of thyroid storm are difficult to carry out. We, the Japan Thyroid Association and Japan Endocrine Society taskforce committee, previously developed new diagnostic criteria and conducted nationwide surveys for thyroid storm in Japan. Detailed analyses of clinical data from 356 patients revealed that the mortality in Japan was still high (∼11%) and that multiple organ failure and acute heart failure were common causes of death. In addition, multimodal treatment with antithyroid drugs, inorganic iodide, corticosteroids and beta-adrenergic antagonists has been suggested to improve mortality of these patients. Based on the evidence obtained by nationwide surveys and additional literature searches, we herein established clinical guidelines for the management of thyroid storm. The present guideline includes 15 recommendations for the treatment of thyrotoxicosis and organ failure in the central nervous system, cardiovascular system, and hepato-gastrointestinal tract, admission criteria for the intensive care unit, and prognostic evaluation. We also proposed preventive approaches to thyroid storm, roles of definitive therapy, and future prospective trial plans for the treatment of thyroid storm. We hope that this guideline will be useful for many physicians all over the world as well as in Japan in the management of thyroid storm and the improvement of its outcome.

    The Mizunami Underground Research Laboratory (MIU) project is being carried out by Japan Atomic Energy Agency in the Cretaceous Toki granite in the Tono area, central Japan. The MIU project is a purpose-built generic underground research laboratory project that is planned for a broad scientific study of the deep geological environment as a basis of research and development for geological disposal of nuclear wastes. One of the main goals of the MIU project is to establish comprehensive techniques for investigation, analysis, and assessment of the deep geological environment. The MIU project has three overlapping phases: Surface-based Investigation (Phase I), Construction (Phase II) and Operation (Phase III). Hydrogeological investigations using a stepwise process in Phase I have been carried out in order to obtain information on important properties such as, location of water conducting features, hydraulic conductivity and so on. Hydrogeological modeling and groundwater flow simulations in Phase I have been carried out in order to synthesize these investigation results, to evaluate the uncertainty of the hydrogeological model and to identify the main issues for further investigations. Using the stepwise hydrogeological characterization approach and combining the investigation with modeling and simulation, understanding of the hydrogeological environment has been progressively improved.

    The nearly perfectly conical profile of Fuji soars 3,776 meters (12,388 feet) above sea level on southern Honshu, near Tokyo. The highest mountain in Japan, Fuji is the country's most familiar symbol. The summit of this graceful, dormant volcano is broken by a crater 610 meters (2,000 feet) in diameter. The crater is ringed by eight jagged peaks. The five Fuji Lakes lie on the northern slopes of the mountain, all formed in the wake of lava flows. Mirrored in the still waters of Kawaguchi-ko, the most beautiful of the five lakes, is a reflection of Fuji. Part of Fuji-Hakone-Izu National Park, Fuji last erupted for a two-month period starting in November 1707, covering Tokyo, some 100 kilometers (60 miles) away, with a layer of ash. According to legend, Fuji arose from the plain during a single night in 286 BC. Geologically, the mountain is much older than this.

    Considered sacred by many, Fuji is surrounded by temples and shrines. Thousands of pilgrims climb the mountain each year as part of their religious practice, hoping to reach the summit by dawn to watch the sunrise. This animated fly-by was created by draping visible and near infrared image data over a digital topography model, created from ASTER's stereo bands. The spatial resolution of both the image and topography is 15 m. The image is centered at 35.3 degrees north latitude, 138.7 degrees east longitude.

    There are two facilities for clinical trials with protons in Japan: the National Institute of Radiological Sciences (NIRS), Chiba, and the Particle Radiation Medical Science Center (PARMS), University of Tsukuba. At the National Institute of Radiological Sciences, patient treatment with the 70 MeV proton beam began in November 1979, and 29 patients were treated through December 1984. Of 11 patients who received protons only, 9 have had local control of the tumor. Two of the 9 patients, suffering from recurrent tumor after radical photon beam irradiation, developed complications after proton treatment. In the patients treated with photons or neutrons followed by proton boost, tumors were controlled in 12 of 18 patients (66.6%), and no complications were observed in this series. Malignant melanoma could not be controlled with the proton beam. A spot-beam-scanning system for protons has been effectively used in the clinical trials to minimize the dose to the normal tissues and to concentrate the dose in the target volume. At the Particle Radiation Medical Science Center, University of Tsukuba, treatment with a vertical 250 MeV proton beam was begun in April 1983, and 22 patients were treated through February 1984. Local control of the tumor was observed in 14 of 22 patients (63.6%), whereas there was no local control in the treatment of glioblastoma multiforme. There have been no severe complications in patients treated at PARMS. The results suggest that local control of tumors will be better with proton beams than with photon beams, whereas additional modalities are required to manage radioresistant tumors.

    The American composer John Adams uses opera to dramatize controversial current events. His 1987 work Nixon in China was about the landmark meeting in 1972 between US President Richard Nixon and Chairman Mao Zedong of China; The Death of Klinghoffer (1991) was a musical re-enactment of an incident in 1985 when Palestinian terrorists kidnapped and murdered a wheelchair-bound Jewish tourist on a cruise ship. Adams's latest opera, Doctor Atomic, is also tied to a controversial event: the first atomic-bomb test in Alamogordo, New Mexico, on 16 June 1945. The opera premièred in San Francisco in 2005, had a highly publicized debut at the Metropolitan Opera in New York in 2008, and will have another debut on 25 February - with essentially the same cast - at the English National Opera in London.

    Goldschmidt, B.

    1990-01-01

    This book is a memoir of rivalries among the Allies over the bomb, by a participant and observer. Nuclear proliferation began in the uneasy wartime collaboration of the United States, England, Canada, and Free France to produce the atom bomb. Through the changes of history, a young French chemist had a role in almost every act of this international drama. This memoir is based on Goldschmidt's own recollections, interviews with other leading figures, and 3,000 pages of newly declassified documents in Allied archives. From his own start as Marie Curie's lab assistant, Goldschmidt's career was closely intertwined with Frances complicated rise to membership in the nuclear club. As a refugee from the Nazis, he became part of the wartime nuclear energy project in Canada and found himself the only French scientist to work (although briefly) on the American atom bomb project.

    In a collaboration with the Atomic Physics group at Argonne and the University of Toledo, the Atomic Physics group at the University of Notre Dame is measuring the fine structure transition energies in highly-charged lithium-like and helium-like ions using beam-foil spectroscopy. Precise measurements of 2s-2p transition energies in simple (few-electron) atomic systems provide stringent tests of several classes of current atomic- structure calculations. Analyses of measurements in helium-like Ar{sup 16+} have been completed, and the results submitted for publication. A current goal is to measure the 1s2s{sup 3}S{sub 1} - 1s2p{sup 3}P{sub 0} transition wavelength in helium-like Ni{sup 26+}. Measurements of the 1s2s{sup 2}S{sub 1/2} - 1s2p{sup 2}P{sub 1/2,3/2} transition wavelengths in lithium-like Kr{sup 33+} is planned. Wavelength and lifetime measurements in copper-like U{sup 63+} are also expected to be initiated. The group is also participating in measurements of forbidden transitions in helium-like ions. A measurement of the lifetime of the 1s2s{sup 3}S{sub 1} state in Kr{sup 34+} was published recently. In a collaboration including P. Mokler of GSI, Darmstadt, measurements have been made of the spectral distribution of the 2E1 decay continuum in helium-like Kr{sup 34+}. Initial results have been reported and further measurements are planned.

  3. Atomic resolution holography.

    Atomic resolution holography, such as X-ray fluorescence holography (XFH)[1] and photoelectron holography (PH), has the attention of researcher as an informative local structure analysis, because it provides three dimensional atomic images around specific elements within a range of a few nanometers. It can determine atomic arrangements around a specific element without any prior knowledge of structures. It is considered that the atomic resolution holographic is a third method of structural analysis at the atomic level after X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS). As known by many researchers, XRD and XAFS are established methods that are widespread use in various fields. XRD and XAFS provide information on long-range translational periodicities and very local environments, respectively, whereas the atomic resolution holography gives 3D information on the local order and can visualize surrounding atoms with a large range of coordination shells. We call this feature "3D medium-range local structure observation".In addition to this feature, the atomic resolution holography is very sensitive to the displacement of atoms from their ideal positions, and one can obtain quantitative information about local lattice distortions by analyzing reconstructed atomic images[2] When dopants with different atomic radii from the matrix elements are present, the lattices around the dopants are distorted. However, using the conventional methods of structural analysis, one cannot determine the extent to which the local lattice distortions are preserved from the dopants. XFH is a good tool for solving this problem.Figure 1 shows a recent achievement on a relaxor ferroelectric of Pb(Mg1/3Nb2/3)O3 (PMN) using XFH. The structural studies of relaxor ferroelectrics have been carried out by X-ray or neutron diffractions, which suggested rhombohedral distortions of their lattices. However, their true pictures have not been obtained, yet. The Nb Kα holograms showed

    Atomic and molecular data are required in a variety of fields ranging from the traditional astronomy, atmospherics and fusion research to fast growing technologies such as lasers, lighting, low-temperature plasmas, plasma assisted etching and radiotherapy. In this context, there are some research groups, both theoretical and experimental, scattered round the world that attend to most of this data demand, but the implementation of atomic databases has grown independently out of sheer necessity. In some cases the latter has been associated with the data production process or with data centers involved in data collection and evaluation; but sometimes it has been the result of individual initiatives that have been quite successful. In any case, the development and maintenance of atomic databases call for a number of skills and an entrepreneurial spirit that are not usually associated with most physics researchers. In the present report we present some of the highlights in this area in the past five years and discuss what we think are some of the main issues that have to be addressed.

  5. Psychotropic dose equivalence in Japan.

    Inada, Toshiya; Inagaki, Ataru

    2015-08-01

    Psychotropic dose equivalence is an important concept when estimating the approximate psychotropic doses patients receive, and deciding on the approximate titration dose when switching from one psychotropic agent to another. It is also useful from a research viewpoint when defining and extracting specific subgroups of subjects. Unification of various agents into a single standard agent facilitates easier analytical comparisons. On the basis of differences in psychopharmacological prescription features, those of available psychotropic agents and their approved doses, and racial differences between Japan and other countries, psychotropic dose equivalency tables designed specifically for Japanese patients have been widely used in Japan since 1998. Here we introduce dose equivalency tables for: (i) antipsychotics; (ii) antiparkinsonian agents; (iii) antidepressants; and (iv) anxiolytics, sedatives and hypnotics available in Japan. Equivalent doses for the therapeutic effects of individual psychotropic compounds were determined principally on the basis of randomized controlled trials conducted in Japan and consensus among dose equivalency tables reported previously by psychopharmacological experts. As these tables are intended to merely suggest approximate standard values, physicians should use them with discretion. Updated information of psychotropic dose equivalence in Japan is available at http://www.jsprs.org/en/equivalence.tables/.

    In 2000, 2001, and 2002, interlaboratory comparison of olfactometry was carried out in order to collect basic data for the establishment of a quality control procedure and the determination of quality criteria for the triangular odour bag method. In 2000, interlaboratory comparison was conducted by using a measurement method for samples taken at smoke stacks. On the other hand, the measurement method for samples taken at boundary lines was used for interlaboratory comparison in 2001. A total of seven olfactometry laboratories in Japan participated in each test, and mean values, repeatability standard deviations, reproducibility standard deviations, and standard deviations under intermediate conditions of detection threshold of ethyl acetate were calculated from the results. These values can be used in a quality control process of olfactometry. In 2002, interlaboratory comparison was carried out by using a measurement method for samples taken at smoke stacks. A total of 137 olfactometry laboratories in Japan participated in the test, and 69% of them lay within the permissible range of the odour index.

    The southeast part of the island of Hokkaido, Japan, is an area dominated by volcanoes and volcanic caldera. The active Usu Volcano is at the lower right edge of the circular Lake Toya-Ko and near the center of the image. The prominent cone above and to the left of the lake is Yotei Volcano with its summit crater. The city of Sapporo lies at the base of the mountains at the top of the image and the town of Yoichi -- the hometown of SRTM astronaut Mamoru Mohri -- is at the upper left edge. The bay of Uchiura-Wan takes up the lower center of the image. In this image, color represents elevation, from blue at the lowest elevations to white at the highest. The radar image has been overlaid to provide more details of the terrain. Due to a processing problem, an island in the center of this crater lake is missing and will be properly placed when further SRTM swaths are processed. The horizontal banding in this image is a processing artifact that will be removed when the navigation information collected by SRTM is fully calibrated. This image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies.

    2014-11-01

    In Japan, liver transplantation was first attempted 50 years ago, around the same time as the development of pediatric surgery. In 1989, clinical liver transplantation in Japan started with a living related-donor transplantation in a boy with biliary atresia. In the early years, the majority of recipients were children worldwide, which is why pediatric surgeons played a major role in the establishment of liver transplantation in Japan. From 1998, most of the indications for pediatric patients needing liver transplantation have been covered by governmental health insurance. Since that year, the annual number of pediatric liver transplantations, mainly living-donor transplantations, has remained stable at around 130. Biliary atresia is still the most common indication, but others like metabolic disease and hepatoblastoma have been increasing. Deceased-donor liver transplantation started in 1999 in Japan, but pediatric donors are very rare. Intestinal transplantation in Japan also started in a pediatric patient with short bowel syndrome in 1996. Deceased-donor intestinal transplantation is also performed, but the number of those on the waiting list for bowel transplantations in Japan has been very limited, probably due to financial constraints and relatively poor long-term results. With the change in the Organ Transplant Law in 2010, organ donations in Japan have increased slightly. Cadaveric split-liver transplantation has the potential to expand the benefit to pediatric recipients. A universal system for the long-term follow-up of pediatric recipients should be established to manage their transition to adulthood.

    Adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome is caused by an ACTH-producing tumor, as is the case with Cushing's disease and ectopic ACTH syndrome (EAS). Diagnosis and differential diagnosis of Cushing's disease from EAS in ACTH-dependent Cushing's syndrome are thus challenging problems in clinical endocrinology. The diagnostic criteria for Cushing's disease in Japan, established by the working group of the Japan Ministry of Health, Labour and Welfare, were originally reported in 2003 and revised in 2007 and 2010. In addition, criteria for subclinical Cushing's disease were established in Japan in 2010. In this review, we evaluate the usefulness and accuracy of the most recent diagnostic criteria. Previous data suggest that as an initial test of Cushing's syndrome, 0.5 mg dexamethasone is more sensitive than 1 mg in the overnight dexamethasone suppression test (DST). Here, we recommend 0.5 mg plus a plasma cortisol cut-off level of 3 µg/dL as a suitable low-dose overnight DST for screening of all cases of ACTH-dependent Cushing's syndrome in Japan. Recently, standardization of cortisol measurements by the ID-LC/MS/MS method using seven assay kits with standard plasma material containing synthetic hydrocortisone-d4 was carried out in Japan. The resulting relative standard deviation was within 10%. The cut-off value remains valid even after standardization of plasma cortisol measurements. Although the recent diagnostic criteria achieve higher diagnostic specificity, care should be taken since data for Cushing's disease partially overlaps with some cases of EAS. Overall, therefore, this review suggests that the accuracy of each diagnostic test should be considered.

  15. Ultraviolet atomic emission detector

    NASA Technical Reports Server (NTRS)

    Braun, W.; Peterson, N. C.; Bass, A. M.; Kurylo, M. J., III (Inventor)

    1972-01-01

    A device and method are provided for performing qualitative and quantitative elemental analysis through the utilization of a vacuum UV chromatographic detector. The method involves the use of a carrier gas at low pressure. The gas carries a sample to a gas chromatograph column; the column output is directed to a microwave cavity. In this cavity, a low pressure microwave discharge produces fragmentation of the compounds present and generates intense atomic emissions in the vacuum ultraviolet. These emissions are isolated by a monochromator and measured by photometer to establish absolute concentration for the elements.

  16. Laser cooling atoms to indistinguishability: Atomic Hong-Ou-Mandel interference and entanglement through spin exchange

    NASA Astrophysics Data System (ADS)

    Kaufman, Adam

    2016-05-01

    Motional control of neutral atoms has a rich history and increasingly interest has turned to single-atom control. In my thesis work, we created a platform to individually prepare single bosonic atoms in highly pure quantum states, by developing methods to laser cool single atoms to the vibrational ground state of optical tweezer traps. Applying this toolset, we observe the atomic Hong-Ou-Mandel effect when we arrange for atom tunneling to play the role of a balanced beam splitter between two optical tweezers. In another experiment, we utilize spin exchange to create entanglement, which we then verify after spatially separating the atoms to observe their non-local correlations. Merging these results with our recent demonstration of deterministic loading of atomic arrays, our results establish the concept of quantum gas assembly, which could be applied to a variety of systems ranging from the production of single dipolar molecules to the assembly of low-entropy arrays of atoms.

    PubMed Central

    Kudo, Masatoshi

    2015-01-01

    Background Hepatocellular carcinoma (HCC) is the fifth most common type of cancer and the third leading cause of cancer-related death worldwide. HCC is most common in Asia, but its prevalence is rapidly increasing in Western countries; consequently, HCC is a global medical issue that urgently needs to be addressed. Japan is the only developed country that has experienced both hepatitis B-related and hepatitis C-related HCC and has a long history of innovation when it comes to new diagnostic and therapeutic modalities, such as computed tomography angiography, anatomical resection, ablation, and transarterial chemoembolization. Among these innovations, a nationwide surveillance program was well established by the 1980s, and such a long-term national program does not exist anywhere else in the world. Summary More than 60% of the initially detected HCCs in Japan are Barcelona Clinic Liver Cancer stage 0 or A, which can undergo curative therapies such as resection, ablation, or transplantation. The recent 5-year survival rate of HCC patients in Japan was 43% and the median survival time was 50 months. In addition, both incidence and mortality rates are drastically declining as a result of the successful surveillance program, careful diagnostic flow, and extensive repeated treatments. Key Message Japan's successful model in the surveillance, diagnosis, and treatment of HCC should be adopted as widely as possible to improve the survival of HCC patients worldwide. PMID:26020028

  7. Atomic magnetometer

    DOEpatents

    Schwindt, Peter [Albuquerque, NM; Johnson, Cort N [Albuquerque, NM

    2012-07-03

    An atomic magnetometer is disclosed which uses a pump light beam at a D1 or D2 transition of an alkali metal vapor to magnetically polarize the vapor in a heated cell, and a probe light beam at a different D2 or D1 transition to sense the magnetic field via a polarization rotation of the probe light beam. The pump and probe light beams are both directed along substantially the same optical path through an optical waveplate and through the heated cell to an optical filter which blocks the pump light beam while transmitting the probe light beam to one or more photodetectors which generate electrical signals to sense the magnetic field. The optical waveplate functions as a quarter waveplate to circularly polarize the pump light beam, and as a half waveplate to maintain the probe light beam linearly polarized.

  8. Greetings: 50 years of Atomic Bomb Casualty Commission-Radiation Effects Research Foundation studies.

    PubMed

    Shigematsu, I

    1998-05-12

    The Atomic Bomb Casualty Commission was established in Hiroshima in 1947 and in Nagasaki in 1948 under the auspices of the U.S. National Academy of Sciences to initiate a long-term and comprehensive epidemiological and genetic study of the atomic bomb survivors. It was replaced in 1975 by the Radiation Effects Research Foundation which is a nonprofit Japanese foundation binationally managed and supported with equal funding by the governments of Japan and the United States. Thanks to the cooperation of the survivors and the contributions of a multitude of scientists, these studies flourish to this day in what must be the most successful long-term research collaboration between the two countries. Although these studies are necessarily limited to the effects of acute, whole-body, mixed gamma-neutron radiation from the atom bombs, their comprehensiveness and duration make them the most definitive descriptions of the late effects of radiation in humans. For this reason, the entire world relies heavily on these data to set radiation standards. As vital as the study results are, they still represent primarily the effects of radiation on older survivors. Another decade or two should correct this deficiency and allow us to measure definitively the human risk of heritable mutation from radiation. We look to the worldwide radiation and risk community as well as to the survivors who have contributed so much to what has been done already to accomplish this goal.

  9. The Atomic Bomb Casualty Commission in retrospect

    PubMed Central

    Putnam, Frank W.

    1998-01-01

    For 50 years, the Atomic Bomb Casualty Commission (ABCC) and its successor, the Radiation Effects Research Foundation (RERF), have conducted epidemiological and genetic studies of the survivors of the atomic bombs and of their children. This research program has provided the primary basis for radiation health standards. Both ABCC (1947–1975) and RERF (1975 to date) have been a joint enterprise of the United States (through the National Academy of Sciences) and of Japan. ABCC began in devastated, occupied Japan. Its mission had to be defined and refined. Early research revealed the urgent need for long term study. In 1946, a Directive of President Truman enjoined the National Research Council of the National Academy of Sciences to develop the program. By 1950, ABCC staff exceeded 1,000, and clinical and genetic studies were underway. Budgetary difficulties and other problems almost forced closure in 1953. In 1955, the Francis Report led to a unified epidemiological study. Much progress was made in the next decade, but changing times required founding of a binational nonprofit organization (RERF) with equal participation by Japan and the United States. New programs have been developed and existing ones have been extended in what is the longest continuing health survey ever undertaken. PMID:9576898

    Cooling atomic gases into strongly correlated quantum phases requires estimates of the entropy to perform thermometry and establish viability. We construct an ansatz partition function for models of Laughlin states of atomic gases by combining high temperature series expansions with exact diagonalization. Using the ansatz we find that entropies required to observe Laughlin correlations with bosonic gases are within reach of current cooling capabilities.

  13. A history of the cancer registration system in Japan.

    PubMed

    Okamoto, Naoyuki

    2008-04-01

    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.

    initiocalculations for research and development of a wide variety of materials were presented from the application side. These included materials for fuel cells, solar cells, lithium batteries, heterogeneous catalysts, oxide semiconductors, bioceramics, light-emitting devices, and many others. It is clear that the gap between theory and application is becoming ever narrower, and collaboration between industry and academia is now de rigueur. Some researchers in industry use ab initio tools every day as part of their research and development activities. The language gap between industry and theory is also narrowing, as shown by the active discussions between presenters and audience. TMI2009 was a satellite meeting of the 2nd International Symposium on Advanced Microscopy and Theoretical Calculations (AMTC2), held from 24-26 June, 2010, in Nagoya, Japan. The AMTC series of meetings was organized to commemorate the establishment of the Nanostructures Research Laboratory (NSRL) at the Japan Fine Ceramics Center (JFCC), and as a daughter event of EXPO 2005 Aichi, Japan. We would like to express our thanks to all the staff of the NSRL who helped run the workshop and contributed immeasurably to its success. Financial support for the workshop from the Grant-in-Aid for Scientific Research on Priority Areas 'Nano Materials Science for Atomic-Scale Modification' from the Ministry of Education, Culture, Sports and Technology (MEXT) and Psi-k Network is also gratefully acknowledged.

  16. Human resources for health development: toward realizing Universal Health Coverage in Japan.

    PubMed

    Akashi, Hidechika; Osanai, Yasuyo; Akashi, Rumiko

    2015-10-01

    Human resources are an important factor in establishing universal health coverage (UHC). We examined Japan's health policies related to development of human resources for health (HRH) toward establishing UHC, and tried to formulate a model for other countries wanting to introduce UHC through reviewing existing data and documents related to Japan's history in developing HRH. In the results, there were four phases of HRH development in Japan: Phase 1 involved a shortage of HRH; Phase 2 was characterized by rapid production of less-educated HRH; Phase 3 involved introduction of quality improvement procedures such as upgrade education for nursing staff or licensing examination for physicians; Phase 4 was characterized by a predominance of formal health professionals. To encourage transition between these phrases, Japan utilized several procedures, including: (i) offering shorter professional education, (ii) fewer admission requirements for professional education, (iii) widespread location of schools, and (iv) the aforementioned quality improvement procedures. Japan was able to introduce UHC during Phase 3, and Japanese health indicators have improved gradually through these phases. Consequently, the government of Japan focused on increasing the quantity of HRH through relaxed admission requirements, shorter education periods, and increasing the numbers of educational facilities, before introducing UHC. Subsequently, the government began focusing on improving quality through procedures such as upgrade education or licensing examination programs to enable less-educated HRH to become fully educated professionals. For governments wanting to introduce UHC, the Japanese model can be a suitable option for HRH development, particularly in resource-poor countries.

    The history of the Red List of Japanese vascular plants is briefly reviewed for editing and research. Especially on the results of recent monitoring, the present status of information and conservation activities on the endangered plants in Japan is discussed and the dynamics of the Japanese flora are taken up, in relation to basic research on plant biodiversity on the Japanese Archipelago. The figures of endangered plants are not very variable during the past quarter of a century, but we can surmise that the conservation of threatened species in Japan has been promoted to some extent. Based on the results of such a study, proposals are made to contribute to the sustainable use of plant biodiversity on the Japanese Archipelago under a global conspectus. PMID:18941303

    Although research studies on gaseous flames in microgravity in Japan have not been one-sided, they have been limited, for the most part, to comparatively fundamental studies. At present it is only possible to achieve a microgravity field by the use of drop towers, as far as gaseous flames are concerned. Compared with experiments on droplets, including droplet arrays, which have been vigorously performed in Japan, studies on gaseous flames have just begun. Experiments on ignition of gaseous fuel, flammability limits, flame stability, effect of magnetic field on flames, and carbon formation from gaseous flames are currently being carried out in microgravity. Seven subjects related to these topics are introduced and discussed herein.

    Following The Declaration of Istanbul 2008, a registration committees of The Japan Society for Transplantation and The Japanese Society for Clinical Renal Transplantation planned to establish a new registry and tracking system for renal transplant recipients and donors supported by a Health Labor Sciences Research Grant by The Ministry of Health Labour and Welfare. In place of the previous paper-based system, we established the new registry and tracking system, JARTRE (Japan Renal Transplantation Registry), using USB memory in 2009. Recipient and donor data were inputted into the USB memory at the transplantation centers. The memory was reviewed a yearly by committees. The recipient and donor registration included details from both. The tracking is performed centrally 3 months, 1 year, and every year after the operation. The advantages of this system are the ease of input, adequacy of the data, and rapid statistical processing. In 2009, we registered 97.9% of new renal transplantation recipients and donors; in 2008 it was more than 81.9% of all past renal transplantation recipients in Japan.

    The author assesses the problem of illegal labor migration to Japan. "Labor policies, regulations, types of immigration violations, and the role of the recruitment industry are described. Most of the estimated 200,000 illegal workers are employed in small and medium sized enterprises, especially construction and manufacturing, which pay them wages well below the normal rate. A key issue is the infringement of human rights of these illegal workers, who lack the protection of labor laws and the social security system."

    In Japan, an important issue is to be able to provide young cancer patients with timely and accurate information about the indications and options for fertility preservation when it is applicable. Therefore, it is necessary to create an environment that assists young cancer patients to make a decision about whether or not to choose fertility preservation. The Japan Society for Fertility Preservation was established in 2012, as Japan's first oncofertility association. Its purpose is to create an environment in which cancer patients can receive evidence-based oncofertility care. Accordingly, the mantra of the Japan Society for Fertility Preservation is: 'While anticancer treatment should be prioritized, fertility preservation may also be chosen to allow the patient to fight cancer without losing hope of a normal future'.

    It is my great pleasure to announce that we were able to publish the Japan Issue in Stem Cells and Development, especially in this year 2014. This year, 2014, is said to be the First Year of Regenerative Medicine in Japan. This movement is likely to be based on the establishment of a new law system regarding regenerative medicine (an Act for Ensuring the Safety of Regenerative Medicine or the so-called Regenerative Medicine Law) and the partial revision of the Pharmaceutical Affairs Law (PAL). Both laws will come into effect in 2014 in this country. These new law systems are expected to have a great impact on the facilitation of R&D related to regenerative medicine and stem cell biology. In the present Japan Issue, some excellent stem cell research in this country will be introduced to celebrate the First Year of Regenerative Medicine in Japan.

  6. The atomic orbitals of the topological atom.

    Ramos-Cordoba, Eloy; Salvador, Pedro; Mayer, István

    2013-06-07

    The effective atomic orbitals have been realized in the framework of Bader's atoms in molecules theory for a general wavefunction. This formalism can be used to retrieve from any type of calculation a proper set of orthonormalized numerical atomic orbitals, with occupation numbers that sum up to the respective Quantum Theory of Atoms in Molecules (QTAIM) atomic populations. Experience shows that only a limited number of effective atomic orbitals exhibit significant occupation numbers. These correspond to atomic hybrids that closely resemble the core and valence shells of the atom. The occupation numbers of the remaining effective orbitals are almost negligible, except for atoms with hypervalent character. In addition, the molecular orbitals of a calculation can be exactly expressed as a linear combination of this orthonormalized set of numerical atomic orbitals, and the Mulliken population analysis carried out on this basis set exactly reproduces the original QTAIM atomic populations of the atoms. Approximate expansion of the molecular orbitals over a much reduced set of orthogonal atomic basis functions can also be accomplished to a very good accuracy with a singular value decomposition procedure.

    Health-care safety management has recently been highlighted for patient safety. However, specialist-based risks in clinical settings have hardly been discussed in Japan so far. A review of dermatological legal claims may delineate these risks. This study examined court precedents from the databases "Courts in Japan" and LEX/DB. Thirty-four dermatology-related civil cases were found from 1968-2006. Of the 34 cases, 32 (94%) were judged and two (6%) were retried. Of these 32 cases, 11 (34%) were appealed to higher courts. Among the 34 litigations, the defendants of eight (23%) were dermatology specialists, 20 (59%) were non-dermatologists and six (18%) of unknown specialty. The defendants' negligence was determined at either level in court in 25 of the 34 cases. The negligence in these 25 cases was categorized into five groups: (i) delayed diagnosis (none); (ii) complication during diagnosis procedure (one, 4%); (iii) inappropriate treatment (nine, 36%); (iv) complication during treatment procedure (10, 40%); and (v) insufficient informed consent (five, 20%). The present study may help to improve strategies for health-care safety management in the dermatological field in Japan.

  9. Underreporting of traffic injuries involving children in Japan

    Background—Significant underreporting of road traffic injuries by the police has been documented, even in developed countries. The objective of this study was to clarify the magnitude of underreporting of police data in Japan. Methods—Police reports were compared with those of the fire department and the Marine and Fire Insurance Association of Japan. Results—The results reveal significant underreporting by police of child vehicle occupant injuries. The true incidence of these injuries in preschoolers was twice as high as that provided by official police reports. Conclusion—Police reports would underestimate the magnitude of vehicle occupant injuries in children and distort any evaluations of preventive initiatives. Improving the police report system, and establishing a more comprehensive trauma registry, that would include data from hospitals and insurance companies should be implemented. PMID:11565993

    Optimisation of computed tomography (CT) parameters is important in avoiding excess radiation exposure. The aim of this study is to establish the diagnostic reference levels (DRL) of CT in Japan by using dose-length product (DLP). Datasheets were sent to all hospitals/clinics which had CT scanner(s) in Gunma prefecture. Data were obtained for all patients who underwent CT during a single month (June 2010), and the distributions of DLP were evaluated for eight anatomical regions and five patient age groups. The DRL was defined as the 25th and 75th percentiles of DLP. Datasheets were collected from 80 of 192 hospitals/clinics (26 090 patients). DLP for head CT of paediatric patients tended to be higher in Japan compared with DRLs of paediatric head CTs reported from the EU or Syria. Although this study was performed with limited samples, DLP for adult patients were at comparable levels for all anatomical regions.

  11. Impact Materials of Takamatsu Crater in Japan

    Shocked quartz materials have been found in Japanese K.T boundary (Hokkaido) and mountains of middle main-islands of Japan, though there are few direct evidence of "natural circular structure" on the surface in Japan. However circular structure has been recently found as a buried crater(up to 150m deep) [1] which is ca. 4km in diameter with -10 mgal of Bouguer gravity anomaly from surrounding Rhyoke granitic region of the southern part of Takamatsu City, Kagawa Prefecture, northeast Shikoku, Japan [1,2,3]. Two boring cores of 300m deep near small mountains inside the crater could not reach the bottom of the crater so far. From model calculation of the negative gravity anomaly, the Takamatsu crater shows deep basin structure up to 1.4km. If the Takamatsu crater is considered to be only impact crater, it is difficult to discuss only surface materials on the crater. But anomalous minerals are found only around small volcanic intrusions inside the crater, which the mixed minerals are clearly different with those of other volcanic intrusions of the Yashima and Goshikidai outside the crater [1,2,3]. The small volcanic intrusions are not origin of large Takamatsu crater, because the small volcanic intrusions are found on whole areas of Kagawa Prefecture. Major different activity of the small intrusions inside the crater is to bring the brecciated materials of the interior (esp. crater sediments). The xenolith materials around only volcanic intrusion of andesite are divided into the following four major mineral materials:(a) round pebble fragments from the Rhyoke granitic basement (Sampling No.15), (b) rock fragments from intruded biotite andesites (Nos. 2,15), (c) impact-induced fragments of shocked Quartz grains (Nos. 2,3,6,15), diaplectic feldspars (Nos. 2,3,6,15), silica glasses (Nos. 2,15) and small Fe-Ni metallic grains (No.15), and (d) small sedimentary fragments of halite and mordenite, as listed in Table 1.

    The GSJ is the main supporting organization of IYPE Japan, which is an implementation body of IYPE in Japan, serving as its secretariat. During the IYPE triennial activity, the GSJ has been supporting development of Geparks, establishment of "the Geology Day" and the Earth Science Olympiad activities with some academic societies, and has distributed geological maps with IYPE logo. The GSJ also established an outreach network "Geo-networks Tsukuba" as a local legacy of the IYPE, and has managed it with a local government, research organizations, nonprofit corporations and local media to increase geological and environmental literacy of public, especially among young people. The GSJ-AIST has also contributed internationally to IYPE by joining two international projects, OneGeology and the CCOP Book project. Geoparks in Japan are characterized by following features. The Japanese Islands and the surrounding seas are situated in the area of unique geologic features; the place where several tectonic plates meet and collide. This causes earthquakes and volcanic activities, and makes Japan one of most dynamic areas on the earth. The dynamics of the earth bring about not only geological hazards but also a lot of blessings. In August of 2009, three Geoparks, the Toya Caldera and Usu Volcano Geopark, the Itoigawa Geopark and the Unzen Volcanic Area Geopark, were accepted to join the Global Geopark Network from Japan for the first time. Since its launch in 2006, the GSJ has been playing a major role in promoting Geoparks in Japan together with Geological Society of Japan. The GSJ hosts the Japan Geopark Committee (JGC) for quality evaluation, serving as the information center of Geoparks in Japan. The Geology Day of Japan (10th of May) has been set up by the academic societies for geology in Japan and GSJ in 2007. The Geology Day is expected to provide the chances for the public to enjoy field trips and excursions and to understand the importance of geo-diversity. The Day

    Winter lightning in Japan is known for such characteristics as frequent occurrence of upward lightning and of positive ground flashes. On the engineering side, higher frequencies of troubles at transmission lines or wind turbines in winter due to lightning than those in summer have been experienced in the winter thunderstorm area of Japan, despite the much smaller number of lightning strokes in winter observed by lightning location systems (LLS). Such frequent troubles by lightning in the cold season are unique in Japan, which have promoted intensive research on winter lightning in Japan since 1980s.

    2010-02-15

    A bright metastable helium (He*) beam is collimated sequentially with the bichromatic force and three optical molasses velocity compression stages. Each He* atom in the beam has 20 eV of internal energy that can destroy a molecular resist assembled on a gold coated silicon wafer. Patterns in the resist are imprinted onto the gold layer with a standard selective etch. Patterning of the wafer with the He{sup *} was demonstrated with two methods. First, a mesh was used to protect parts of the wafer making an array of grid lines. Second, a standing wave of {lambda}=1083 nm light was used to channel and focus the He* atoms into lines separated by {lambda}/2. The patterns were measured with an atomic force microscope establishing an edge resolution of 80 nm. Our results are reliable and repeatable.

    A serological survey for antibodies to minute virus of canines (MVC) by use of a hemagglutination-inhibition (HI) test was performed on sera collected from dogs in the Tokai area of Japan. Forty-one of 266 (15.4%) sera had positive titers of 1:40 or higher against the MVC. Results suggest that MVC may have been present in dogs in Japan since, at least, 1990. From this serosurvey, MVC appears to be established in the dog population in Japan. MVC may have a role as a newly recognized viral pathogen of dogs in Japan.

    The JTEC panel found that, after four decades of development in electronics and manufacturing technologies, Japanese electronics companies are leaders in the development, support, and management of complex, low-cost packaging and assembly technologies used in the production of a broad range of consumer electronics products. The electronics industry's suppliers provide basic materials and equipment required for electronic packaging applications. Panelists concluded that some Japanese firms could be leading U.S. competitors by as much as a decade in these areas. Japan's technology and manufacturing infrastructure is an integral part of its microelectronics industry's success.

    The present work deals with measurements of the droplet size distribution in an ultrasonic atomizer using photographic analysis with an objective of understanding the effect of different equipment parameters such as the operating frequency, power dissipation and the operating parameters such as the flow rate and liquid properties on the droplet size distribution. Mechanistic details about the atomization phenomena have also been established using photographic analysis based on the capture of the growth of the instability and sudden ejection of droplets with high velocity. Velocity of these droplets has been measured by capturing the motion of droplets as streaks. It has been observed that the droplet size decreases with an increase in the frequency of atomizer. Droplet size distribution was found to change from the narrow to wider range with an increase in the intensity of ultrasound. The drop size was found to decrease with an increase in the fluid viscosity. The current work has clearly highlighted the approach for the selection of operating parameters for achieving a desired droplet size distribution using ultrasonic atomization and has also established the controlling mechanisms for the formation of droplet. An empirical correlation for the prediction of the droplet size has been developed based on the liquid and equipment operating properties.

    Unfortunately there is no heritage site of astronomy until now in Japan. Here we report several candidates based on the importance from the historical point of view.One is the “Nisshinkan” Astronomical Observatory site of the Edo era. Many observatories were established in the Edo era, including "Asakusa observatory" of a Shogunate Government. However, most of them have been disappeared by the urban development. The only one remained until now is the “Nissshinkan” Astronomical Observatory site of which the basement made of stones is preserved. This was made in 1803 mainly for educational purpose at the “Nisshinkan” which was a local school for the Samurai’s children in Aizu area. Although a wooden building of the school was lost by a war, but this observatory mark exists because large basement of a few meters high remained. This site is now designated as a cultural asset by the local government, and can be recognized even at the present time.Another is the Repsold Meridian Transit which was designated as the Important Cultural Property of Japan in 2011. A Repsold meridian transit instrument is a telescope with a diameter of 13.5 cm and a focal length of 212 cm for meridian transit observations. It was manufactured by A. Repsold & Soehne Co. Ltd. in Hamburg, Germany in 1880, and purchased by the Naval Observatory and imported to Japan in 1881, becoming one of the most important telescopes in the dawning era of modern astronomy in Japan. The telescope escaped being damaged in the Great Kanto Earthquake, and continued to be used as a main telescope for time determination, longitude observation, and astrometry of heavenly bodies till the end of the 1950s. We confirmed that this telescope has retained its original form in 2008, and after restoration and repair, the telescope was widely opened for exhibition to the public. In June, 2011 it was designated as one of the important cultural properties of Japan. The related old instruments which brought modern

    Development and Future Perspectives of Behavioral Medicine in Japan The study of the "Type A behavior pattern and myocardial infarction" was one of the main themes in the early stage of Behavioral Medicine. After that, behavior modification came to be widely applied to the treatment of various kinds of chronic diseases, and a general concept of Behavioral Medicine was subsequently formed. The Japanese Society of Behavioral Medicine was established in 1992 and is comprised of researchers in the fields of clinical medicine, social medicine, and psycho-behavioral science. Recently, we devised a core curriculum for behavioral science and behavioral medicine and have published a Japanese version of the "Textbook of Behavioral Medicine" in conformity with it. It is a primer that includes all of the basics and clinical applications of Behavioral Medicine and is edited as a manual that can be utilized in clinical practice. We hope this book will contribute to the development of Behavioral Medicine in Japan, to a more healthy life for our people, and to the improvement of the QOL of our patients. In this paper, I discuss the future perspectives from my personal opinion while looking back on the history of Behavioral Medicine in Japan.

    Psychiatric nurses have played a significant role in disseminating cognitive behavioral therapy (CBT) in Western countries; however, in Japan, the application, practice, efficiency, and quality control of CBT in the psychiatric nursing field are unclear. This study conducted a literature review to assess the current status of CBT practice and research in psychiatric nursing in Japan. Three English databases (MEDLINE, CINAHL, and PsycINFO) and two Japanese databases (Ichushi-Web and CiNii) were searched with predetermined keywords. Fifty-five articles met eligibility criteria: 46 case studies and 9 comparative studies. It was found that CBT took place primarily in inpatient settings and targeted schizophrenia and mood disorders. Although there were only a few comparative studies, each concluded that CBT was effective. However, CBT recipients and outcome measures were diverse, and nurses were not the only CBT practitioners in most reports. Only a few articles included the description of CBT training and supervision. This literature review clarified the current status of CBT in psychiatric nursing in Japan and identified important implications for future practice and research: performing CBT in a variety of settings and for a wide range of psychiatric disorders, conducting randomized controlled trials, and establishing pre- and postqualification training system.

    The Role of Organ Transplant Network are the encouragement of the organ transplantation and fair organ sharing. Its principled are united, neutral open and nonprofit organization, so as to secure the fair and quick organ sharing based on the uniform allocation policy. Japan Kidney Transplant Network was established in 1995 nad reorganized into multi-organ sharing network, Japan Organ Transplant Network in 1997, when Japan Organ transplant Act was enacted. It consists of transplant coordinators, physicians, transplant surgeons, kidney banks, local administration, academic standings, other organization/associations and others. There are several committee, in which special subjects on organ transplantation and related matters are consulted, and review system in which each case is assessed and judged. And principal and essential items are decided by the board of members and then by the general assembly. The new computer system was introduced and registrants data are renewed every year, and recipient selection is done based on the latest registrants data. Standardized HLA examination tray was introduced and class II antigen was examined by means of DNA typing since 1997, which enabled more precise and accurate search. Hereafter, the education and encouragement of transplant coordinators to raise themselves and the more effective and extended distribution of donor cards are indispensable to promote organ donation/transplantation.

    Clinical identity of nonalcoholic steatohepatitis (NASH) has established it as a chronic liver disease since the 1990s in the USA and in the 21st century in Japan, although its significance is not well recognized in Japanese society. It is characterized as a chronic liver disease, differentiated from viral liver disease and alcoholic liver disease. Nonalcoholic fatty liver disease (NAFLD) comprises nonalcoholic fatty liver (NAFL) and NASH. NASH is considered to be the hepatic manifestation of a metabolic syndrome. It is understood that among individuals with NAFLD, NAFL is a benign condition, whereas NASH can progress to cirrhosis and ultimately to hepatocellular carcinoma. The precise mechanism of NASH is poorly understood, although insulin resistance, oxidative stress and multiple parallel hits theory have been reported. Computed tomography and ultrasonography are performed to detect NAFLD, but these are not sufficient to distinguish between NAFL and NASH. The distinct diagnosis of NAFL and NASH is currently made by liver biopsy, requiring hospitalization. Therefore, there is an urgent need to develop simple, non-invasive markers that can accurately distinguish between NASH and NAFL. In Japan, the number of NASH patients is estimated to be about 1 million. The treatment of NASH comprises changes in life style, including eating habits and exercise that will lead to weight loss, and drug intake, including vitamin E. Based on the global increase in obese people, NASH as a chronic liver disease will become the most important chronic liver disease in the 21st century, not only in Japan but also worldwide.

    The Medical Image Processing System (MIPS) plan is a standard plan for the online communication of imaging data in Japan. The ACR-NEMA Standard is not always easy for manufacturers in Japan to comply with. This situation led to the formulation of MIPS Plan Minimum Set-87 (MIPS Standard-87), which uses reciprocal corresponding patterns to ACR-NEMA Standards. The working groups on current and future trends study data collected with a questionnaire in 1985 regarding (1) current technology and (2) its future direction as well as (3) the status of utilization of medical imaging and its data management. In 1986, they engaged in further investigations on the above subjects and presented their views on standardization. Conformance tests have been discussed and the conclusions were published in 1987 and 1988. Protocol conversion between MIPS Standard-87 and ACR-NEMA Standard was also discussed and the conclusions were reported. At the beginning of 1988, validation from medical viewpoints, e.g. the setting of anatomical position codes, was requested by medical members. Each layer of MIPS is compared briefly with the ACR-NEMA Standard. A small picture archiving and communication (PAC) system for three X-ray computer tomography units (X-CTs) has been constructed at the University of Tokyo Hospital. In this implementation, X-CTs and an imaging filing system are successfully connected by MIPS Standard-87. Some problems of MIPS Standard-87 are mentioned.

    The US Army Engineering & Support Center, Huntsville (USAESCH), and the US Marine Corps Base (MCB), Okinawa, Japan retained Idaho National Laboratory (INL) to conduct a Transformer Efficiency Assessment of “key” transformers located at multiple military bases in Okinawa, Japan. The purpose of this assessment is to support the Marine Corps Base, Okinawa in evaluating medium voltage distribution transformers for potential efficiency upgrades. The original scope of work included the MCB providing actual transformer nameplate data, manufacturer’s factory test sheets, electrical system data (kWh), demand data (kWd), power factor data, and electricity cost data. Unfortunately, the MCB’s actual data is not available and therefore making it necessary to de-scope the original assessment. Note: Any similar nameplate data, photos of similar transformer nameplates, and basic electrical details from one-line drawings (provided by MCB) are not a replacement for actual load loss test data.

    The US Army Engineering & Support Center, Huntsville (USAESCH), and the US Marine Corps Base (MCB), Okinawa, Japan retained Idaho National Laboratory (INL) to conduct a Transformer Efficiency Assessment of “key” transformers located at multiple military bases in Okinawa, Japan. The purpose of this assessment is to support the Marine Corps Base, Okinawa in evaluating medium voltage distribution transformers for potential efficiency upgrades. The original scope of work included the MCB providing actual transformer nameplate data, manufacturer’s factory test sheets, electrical system data (kWh), demand data (kWd), power factor data, and electricity cost data. Unfortunately, the MCB’s actual data is not available and therefore making it necessary to de-scope the original assessment. Note: Any similar nameplate data, photos of similar transformer nameplates, and basic electrical details from one-line drawings (provided by MCB) are not a replacement for actual load loss test data. It is recommended that load measurements are performed on the high and low sides of transformers to better quantify actual load losses, demand data, and power factor data. We also recommend that actual data, when available, be inserted by MCB Okinawa where assumptions have been made and then the LCC analysis updated. This report covers a generalized assessment of modern U.S. transformers in a three level efficiency category, Low-Level efficiency, Medium-Level efficiency, and High-Level efficiency.

  12. On earthquake prediction in Japan.

    PubMed

    Uyeda, Seiya

    2013-01-01

    Japan's National Project for Earthquake Prediction has been conducted since 1965 without success. An earthquake prediction should be a short-term prediction based on observable physical phenomena or precursors. The main reason of no success is the failure to capture precursors. Most of the financial resources and manpower of the National Project have been devoted to strengthening the seismographs networks, which are not generally effective for detecting precursors since many of precursors are non-seismic. The precursor research has never been supported appropriately because the project has always been run by a group of seismologists who, in the present author's view, are mainly interested in securing funds for seismology - on pretense of prediction. After the 1995 Kobe disaster, the project decided to give up short-term prediction and this decision has been further fortified by the 2011 M9 Tohoku Mega-quake. On top of the National Project, there are other government projects, not formally but vaguely related to earthquake prediction, that consume many orders of magnitude more funds. They are also un-interested in short-term prediction. Financially, they are giants and the National Project is a dwarf. Thus, in Japan now, there is practically no support for short-term prediction research. Recently, however, substantial progress has been made in real short-term prediction by scientists of diverse disciplines. Some promising signs are also arising even from cooperation with private sectors.

  13. Palliative care for advanced dementia in Japan: knowledge and attitudes.

    PubMed

    Nakanishi, Miharu; Miyamoto, Yuki

    This study examined factors contributing to the knowledge and attitudes of nursing home staff regarding palliative care for advanced dementia in Japan. A cross-sectional survey of 275 nurses and other care workers from 74 long-term care facilities was conducted across three prefectures in August 2014. The Japanese versions of the Questionnaire on Palliative Care for Advanced Dementia (qPAD) and Frommelt Attitudes Toward Care of the Dying scale, Form B (FATCOD-B-J) were used. Greater knowledge was exhibited among nursing home staff in facilities that established a manual for end-of-life care. Higher levels of positive attitudes were observed among nursing home staff in facilities that had established a manual and those in facilities with a physician's written opinions on end-of-life care. An organisational effort should be explored to establish end-of-life care policies among nursing home staff for advanced dementia.

    Pathogenic fungi that are non-native in Japan are highly virulent and present a significant health hazard to persons in the environment into which they are introduced. Little is known, however, about the precise trend of infection by imported mycoses in Japan. To clarify this issue, all available cases were collected through a search of MEDLINE and Japana Centra Revuo Medicine and analyzed. Also included in this analysis were cases not reported in the literature for which the authors provided identification of the fungi, diagnosis, or treatment. The analysis revealed that, for three diseases, the number of imported mycoses cases in Japan is much higher than previously reported: 31 cases of coccidioidomycosis, 34 cases of histoplasmosis, and 17 cases of paracoccidioidomycosis. Additionally, one case of penicilliosis marneffei was found. The most rapid increase in the incidence of these mycoses occurred from 1991 to 1995. Analysis of the patients' profiles provided the following information: (1) coccidioidomycosis infection in Japan is increasing very rapidly, (2) Japan might be an endemic area of histoplasmosis infection, (3) histoplasmosis is a potentially fatal disease; and (4) reliable serodiagnostic methods have been used only infrequently. Because of the increase of international travel and immigration, the incidence of imported mycoses in Japan is expected to continue rising, and mycoses that have never been reported in Japan, such as blastomycosis, might also be encountered in the near future. To cope with this newly emerging health problem to residents of Japan, the Japanese medical system must train its members to identify and treat mycoses.

    The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in 2013, and its official Japanese version was published in 2014. The Japanese Government uses classifications from the 10th revision of the I nternational C lassification of D iseases (ICD-10) to categorize disorders and determine treatment fees. However, since the publication of the DSM-III, the use of the DSM system has become prevalent in research and educational settings in Japan. In addition to traditional psychiatry, both the ICD and the DSM are taught by many Japanese medical schools, and virtually all clinical research and trials refer to the DSM to define targeted disorders. Amid the current backdrop in which the reputation of the DSM-5 is being established, the editorial board of P sychiatry and C linical N eurosciences has asked Japanese experts across 12 specialties to examine the structure of the DSM-5, including the following categories: Neurodevelopmental Disorders, Schizophrenia Spectrum Disorders, Major Depression, Bipolar Disorders, Obsessive-Compulsive Disorders, Somatic Symptom Disorder, Eating Disorders, Substance-Related and Addictive Disorders, Gender Dysphoria, and Neurocognitive Disorders. Although opinions were only obtained from these selected experts, we believe that we have succeeded, to a certain extent, in presenting views that are representative of each specialty.

    2015-02-01

    The current outbreak of Ebola virus disease (EVD) is due to a lack of resources, untrained medical personnel, and the specific contact-mediated type of infection of this virus. In Japan's history, education and mass vaccination of the native Ainu people successfully eradicated epidemics of smallpox. Even though a zoonotic virus is hard to control, appropriate precautions and personal protection, as well as anti-symptomatic treatment, will control the outbreak of EVD. Ebola virus utilizes the antibody-dependent enhancement of infection to seed the cells of various organs. The pathogenesis of EVD is due to the cytokine storm of pro-inflammatory cytokines and the lack of antiviral interferon-α2. Matricellular proteins of galectin-9 and osteopontin might also be involved in the edema and abnormality of the coagulation system in EVD. Anti-fibrinolytic treatment will be effective. In the era of globalization, interviews of travelers with fever within 3 weeks of departure from the affected areas will be necessary. Not only the hospitals designated for specific biohazards but every hospital should be aware of the biology of biohazards and establish measures to protect both patients and the community.

  7. [Professionalization of public health officers in Japan].

    2008-01-01

    In this paper, I describe how public health officers in Japan in the period of the late Taisho and early Showa eras claimed their position as professionals in the sanitary administrations of central and local governments. In the background of this push for recognition, there were related international and national movements. Internationally, public health ministries were established in developed countries and the League of Nations Health Organization (LNHO) was created. LNHO wanted to improve the level of public health officials world-wide, so the organization sponsored international exchanges of officials. These activities made a strong impression on Japanese public health officials, who realized that they belonged to an internationally recognized profession and that they needed to work hard to improve the substandard Japanese public health situation. Meanwhile, at the level of domestic politics, there were several movements of technical experts in different fields of government administration that worked to fight the unfair treatment of administrative officials, a situation that had existed since Meiji Period. The public health officers collaborated with the other technical experts to improve their positions and to play key roles in society. But while the other technical experts actively pursued social leadership, public health officials wanted to remain scientists. This is because the sanitary departments in the local governments were organized within police departments. In this environment, the law was dominant and science was secondary. But public health officials insisted that the basis of public health should be science, so they emphasized their scientific expertise.

    Ikegami, Naoki; Campbell, John Creighton

    2004-01-01

    As Japan's economy declined, more intensive control of prices and even volume through the fee schedule, plus increases in various copayment rates, led to an actual reduction of medical spending in 2002 for the first time in history. To augment established mechanisms of cost containment, case-mix-based inclusive fees for inpatient care were introduced in university hospitals in 2003 and are planned for subacute and long-term care. However, substantial reform, including the introduction of market-based medicine, is not likely to occur in other areas. Progress in making the delivery system more accountable to patients has been meaningful but slow.

JSPEC elaborates strategies of science and technology, program planning and promotion of Space Exploration activities through domestic and international collaborations. And at the same time, the Specific R&D activities for engineering and science development, operation and other related activities for spacecraft are also performed there, including the research and analysis of scientific and technical aspects for future missions. Simply speaking, the JSPEC of JAXA looks at both Exploration together with Science Missions. The activity includes the Moon, Mars and NEOs plus Primitive Bodies where humans someday may stay or may utilize in future. This January, the Lunar Exploration WG was established under the government, and started the strategic discussion at the government level on how to go about the lunar exploration in Japan. The program strategy made a report this January and made a recommendation that Japan should have a lunar lander until middle of 2010s. JAXA started its 2nd 5-year plan from 2008, and JAXA completed the MDR (Mission Definition Review) for the SELENE-2 last July, and established the Phase-A study team for it. JAXA believes it leads to International Cooperation, Discovery and Innovation and shall consist of two types of missions. The first one is the Robotic Lunar Missions, in which JAXA will make an in-depth scientific measurements and utilization, until the middle of 2010s. The other one is the Human Lunar Missions, in which the missions anyhow shall be autonomous with its own objectives, making use of humans related technologies, while pursuing the Japanese astronaut on the moon as early as possible in international activity to commensurate with its international status.

    Recombinant DNA technology was developed in the United States in the early 1970s. Leading scientists held an international Asilomar Conference in 1975 to examine the self regulation of recombinant DNA technology, followed by the U.S. National Institutes of Health drafting the Recombinant DNA Research Guidelines in 1976. The result of this conference significantly affected many nations, including Japan. However, there have been few historical studies on the self-regulation of recombinant technologies conducted by scientists and government officials in Japan. The purpose of this paper is to analyze how the Science Council of Japan, the Ministry of Education, Science adn Culture, and the Science and Technology Agency developed self-regulation policies for recombinant DNA technology in Japan in the 1970s. Groups of molecular biologist and geneticists played a key role in establishing guidelines in cooperation with government officials. Our findings suggest that self-regulation policies on recombinant DNA technology have influenced safety management for the life sciences and establishment of institutions for review in Japan.

    Katsuda, Yoshio; Minamite, Yoshihiro; Vongkaluang, Charunee

    2011-12-08

    With the advancement from natural pyrethrins to synthetic pyrethroids, their applications have expanded from household insecticides for indoor use against sanitary pests to outdoor use for agriculture, forestry, animal health, termite control, and many other pest situations. However, high fish toxicity and development of pyrethroid resistance in some pests have been cited as common shortcomings of pyrethroids. To overcome these pyrethroid problems such as high fish toxicity, Katsuda and fellow scientists invented silafluofen by introducing a silicone atom into the pyrethroidal chemical structure in 1984. In addition to the high insecticidal activity and low mammalian toxicity, this compound features low fish toxicity, chemical stability under sunlight, in the soil and under alkaline environments. These features make silafluofen unique among pyrethroids. In Japan, silafluofen has been used as an agricultural insecticide for 15 years since 1995 for various plants, especially useful for paddy rice protection because of its low fish toxicity. Over the last 20 years, silafluofen-based termiticides including emulsifiable concentrate (EC) and oil formulations have been widely used in Japan for soil treatment and timber treatments. Additional silafluofen product lines include anti-termitic plastic sheets which are laid under buildings. In this paper, literature on the development of silafluofen and its use in Japan are reviewed. On the other hand, in Thailand, we proceeded with development works of silafluofen-based termiticides from 2005 by starting laboratory efficacy tests and field efficacy tests in Phuket. Both laboratory and field tests showed good efficacy as a soil termiticide, suggesting that the material will perform well for commercial use in high biological hazard environments such as Thailand and can be used in environments close to water where fish toxicity might be a concern with other pyrethroids.

    City Institute Laboratory of Health and Environment) DNA fingerprinting establishes the genetic relatedness of Mycobacterium tuberculosis isolates and has become a powerful tool in tuberculosis epidemiology. To use DNA fingerprinting to assess the efficacy of current tuberculosis infection-control practices. Combining conventional epidemiologic techniques with DNA fingerprinting of M. tuberculosis can improve the understanding of how tuberculosis is transmitted. Patients were assigned to clusters based on mycobacterial isolates with identical DNA fingerprints. Clusters were assumed to have arisen from recent transmission. We analyzed M. tuberculosis isolates from patients reported to the tuberculosis registry by RFLP techniques. These results were interpreted along with demographic data. Patients infected with the same strains were identified according to their RFLP patterns, and patients with identical patterns were grouped in clusters. RFLP patterns of high incidence districts have more variations than other areas. This suggests that the source of tuberculosis infection are quite diverse and complicated. Tuberculosis patients may accumulate to high incidence districts from other places after infection. 4.

    The objective of the study was to explore the survival trends of centenarians in Japan. A cohort of centenarians born between 1881 and 1900 was analysed based on national census data, and the average life expectancy at 100 years of age, risk of death and maximum age were estimated. An analysis of covariance and a Cox regression analysis were performed to explore the factors associated with life expectancy and risk of death. The death rates in centenarians tended to decrease with birth year, and the average life expectancy from the age of 100 slightly increased at a rate of 0.013 years (95% CI: 0.007-0.019) by birth year in men and 0.026 in women. Women had a longer life expectancy than men, with a difference of 0.174 years (95% CI: 0.071-0.277) at birth year 1881 and increasing by 0.013 years per year thereafter. The risk of death in both sexes decreased significantly by birth year over the course of the period analysed, and the risk of death in men was 1.16 (95% CI: 1.14-1.19) times that of women. In women, death rates at every age significantly decreased with birth year over the course of the period analysed until age 104. However, this trend did not hold true for ages 105 and older. The average life expectancy of centenarians at the age of 100 in Japan increased by birth year in the 1881-1900 birth cohort. In addition, Japanese centenarians had the lowest death rates among several countries.

    Early this century Ernest Rutherford established the nuclear model of the hydrogen atom, presently taught as representing the best visual model after modification by Niels Bohr and Arnold Sommerfeld. It replaced the so-called "plum pudding" model of J. J. Thomson which held sway previously. While the Rutherford model represented a large step forward in our understanding of the hydrogen atom, questions remained, and still do.

    Following the atomic bomb attacks on Japan in 1945, scientists from the United States and Japan joined together to study the Hibakusha - the bomb affected people in what was advertised as a bipartisan and cooperative effort. In reality, despite the best efforts of some very dedicated and earnest scientists, the early years of the collaboration were characterized by political friction, censorship, controversy, tension, hostility, and racism. The 70-year history, scientific output and cultural impact of the Atomic Bomb Casualty Commission and the Radiation Effects Research Foundation are described in the context of the development of Occupied Japan.

    At the end of the revolution against the Tokugawa Shogun in 1868, the new Meiji government introduce Western medicine and science into Japan. Dental education, however, was neglected by the new regime. Dr. Kisai Takayama, a Samurai warrior turned dentist, realized this and established the first dental school in Japan in 1890. Meeting a definite need, the school expanded several times and introduced into the country standards which raised Japanese dental education to the level of that in the Western world. In 1990, the hundredth anniversary celebration of the school was held, following the completion of the school's magnificent new campus in 1981 and a new headquarters building in 1990.

    In Japan, the practice of infection control in healthcare settings has a short history of less than 3 decades. Before that, infection control practices were far from perfect and even ignored. This review summarizes changes in infection control in Japan since the 1980s and offers some comparisons with practices in foreign countries, especially the United States. Infection control is far better now than 25 years ago, but there remain fundamental issues that limit the development of better infection control practices. These problems include insufficient funding and human resources due to the socialized healthcare insurance system in Japan and the lack of interest in infection control research.

    Anaplasma species of the family Anaplasmataceae, order Rickettsiales are tick-borne organisms that can cause disease in animals and humans. In Japan, all recognized species of Anaplasma (except for Anaplasma ovis) and a potentially novel Anaplasma sp. closely related to Anaplasma phagocytophilum have been reported. Most of these detected tick-borne pathogens are believed to be lowly pathogenic in animals in Japan although the zoonotic A. phagocytophilum has recently been reported to cause clinical signs in a dog and in humans. This review documents the studies and reports about Anaplasma spp. in Japan. PMID:27956767

    2016-01-01

    The input history of 236U to the surface water of the Japan Sea was reconstructed through measurement of the 236U/238U atom ratio in annual bands of a coral skeleton which was collected at Iki Island in the Tsushima Strait, the main entrance to the Japan Sea. The 236U/238U atom ratios and concentrations of U isotopes were measured for the period 1935-2010 using AMS and ICP-MS. The 236U/238U atom ratios revealed three prominent peaks: 4.51 × 10-9 in 1955, 6.15 × 10-9 in 1959 and 4.14 × 10-9 in 1963; thereafter the isotope ratios gradually decreased over the next several decades, attaining a value of ca.1.3 × 10-9 for the present day. A simplified depth profile model for 236U in the Japan Sea, using the reconstructed 236U value for the surface water together with observed depth profiles for 236U in the water column in 2010, yielded diffusion coefficients of 3.4-5.6 cm2/s for 6 sampling points. The diffusion coefficient values obtained for the northern stations were relatively large, and fitting uncertainty was also larger for stations in the northern region. It may be presumed that the distribution of 236U in the water columns have been influenced not only by diffusion but also by subduction of the surface water in the Japan Sea.

  12. Deterministically Entangling Two Remote Atomic Ensembles via Light-Atom Mixed Entanglement Swapping

    PubMed Central

    2016-01-01

    Entanglement of two distant macroscopic objects is a key element for implementing large-scale quantum networks consisting of quantum channels and quantum nodes. Entanglement swapping can entangle two spatially separated quantum systems without direct interaction. Here we propose a scheme of deterministically entangling two remote atomic ensembles via continuous-variable entanglement swapping between two independent quantum systems involving light and atoms. Each of two stationary atomic ensembles placed at two remote nodes in a quantum network is prepared to a mixed entangled state of light and atoms respectively. Then, the entanglement swapping is unconditionally implemented between the two prepared quantum systems by means of the balanced homodyne detection of light and the feedback of the measured results. Finally, the established entanglement between two macroscopic atomic ensembles is verified by the inseparability criterion of correlation variances between two anti-Stokes optical beams respectively coming from the two atomic ensembles.

    According to an old historical text, Nihonshoki [Chinese and Korean characters: see text]), there are records of medical doctors ([Chinese and Korean characters: see text]) and herbal pharmacists ([Chinese and Korean characters: see text]) being dispatched to Japan as early as 554 A.D. ([Chinese and Korean characters: see text]). More recently, a clinic ([Chinese and Korean characters: see text]) for Japanese residents in Pusan was established in 1877. Advanced modern pharmacy from Japan began to be introduced to Korea after 1909. Based on an agreement between the Korean and Japanese governments, Korean students sent to Japan with expenses funded by the Japanese government became a systematic program after 1965. As a result, Koreans who earned Ph.D.s from Japanese universities became a majority in the faculties of Korean schools of pharmacy. However, this trend drastically shifted in the years after 1990, at which time the primary nation for earning Ph.D.s became the United States; the number of students studying in Japan has become very low recently. In this study, six ex-students who studied in Japan were interviewed and the results were analyzed. Furthermore, the past, present and future perspectives of Korean students in Japan were discussed while focusing on the system of Korean students being sent to Japan with expenses funded by the Japanese government.

  19. Revision of the genus Buchneria (Bryozoa, Cheilostomata) from Japan.

    2012-01-01

    Buchneria dofleini (Buchner, 1924), type species of Buchneria Harmer, 1957,was first described from material collected in 1904-1905 from Sagami Bay, Japan, but the type specimens had not been reexamined since the original description. In this study, I examined specimens of Buchneria from historical collections and material recently collected near Akkeshi, Hokkaido, Japan. Three Buchneria species were detected, two from Sagami Bay that Ortmann (1890) had placed in Escharoides, and one from Akkeshi that Androsova (1958) had described as Porella variabilis. I concluded that Buchneria dofleini is a junior synonym of Escharoides teres Ortmann, 1890; selected a lectotype for Escharoides teres among Ortmann's syntypes; and established the new combination Buchneria teres (Ortmann, 1890), which becomes the type species of Buchneria. I also established the new combination Buchneria rhomboidalis (Ortmann, 1890) and selected a lectotype among Ortmann's syntypes. Porella variabilis is transferred to Buchneria establishing the new combination Buchneria variabilis (Androsova, 1958). Here the three new combinations are redescribed and a key to the Japanese Buchneria species is provided. Finally, I transferred Buchneria to Bryocryptellidae on the basis of ovicell and orifice morphology. Therefore, Buchneria now includes a total of three species; Buchneria sinuata Harmer, 1957, a species from Indonesia that has hitherto been placed in this genus, is almost certainly not congeneric with other Buchneria. As far as is now known, Buchneria is endemic to northern Japan and the northern Sea of Japan.

The indicated trend for this compound, along with other results, provides the basis for a possible explanation of the anomolous values that have been obtained for hydrogen atom thermal parameters.

    Cerebral palsy is associated not merely with impairments of posture and locomotion, but also with various other problems. Medical illnesses should be treated by an adequate system. Emotional disturbances require a psychological support. Communication disorders may be overcome with proper modern equipments Perceptional deficits and sensory impairments should also be addressed. Care systems for physically handicapped children in Japan were established by the concept of ryoiku, a term in Japanese created about fifty years ago by K. Takagi, Professor of the Department of Orthopedics, University of Tokyo. This term can hardly be translated into English, bot in my view stands for a comprehensive approach comprising orthopedic treatments, educational programs and vocational trainings. Based on this concept, Dr. Takagi founded an institution for the physically handicapped in 1942; followed by establishment of similar institutions in all areas of Japan after World War II. Despite its historical role, ryoiku does not meet any more the current standard of care for cerebral palsy. We need now a new comprehensive term and management systems. A novel medical subdivision "medicine for developmental handicaps" may also be necessory. In this paper I made an overview of current problems of children and adults with cerebral palsy. I proposed a new concept of ryoiku and emphasized the need for the new medicine to treat developmental handicaps.

    Dietary aluminum (Al) intake by young children, children, youths, and adults in Japan was estimated using the market basket method. The Al content of food category (I–VII) samples for each age group was determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The Al content in processed foods and unprocessed foods ranged from 0.40 to 21.7 mg/kg and from 0.32 to 0.54 mg/kg, respectively. For processed foods in all age groups, the Al content in food category VI samples, sugar and confections/savories, was the highest, followed by those in category II, cereals. The daily dietary Al intake from processed foods was much larger than that from unprocessed foods. The mean weekly percentages of the provisional tolerable weekly intake (PTWI, established by the joint FAO/WHO Expert Committee on Food Additives in 2011) from processed foods for all age groups are 43.1, 22.4, 17.6 and 15.1%, respectively. Only the highest consumer Al exposure value (>P95) of the young children group exceeded the PTWI. PMID:25473496

  12. Deoxygenation of Lake Ikeda, Japan

    2010-12-01

    Lake Ikeda (Kagoshima prefecture, Japan) is a deep lake with a maximum depth of 233 m. Monitoring data of lake Ikeda exist since 1975. We have analyzed the long-term variability in the water conditions of Lake Ikeda. Recently, Lake Ikeda has exhibited the phenomenon of incomplete overturning because of climate warming. The concentrations of DO (dissolved oxygen) in the deepest parts of the lake have reduced. This phenomenon was observed to have started in the 1980s, and gradually, the deepest parts of the lake became anoxic. Later, the anoxic layer became thicker. Currently, winter mixing in Lake Ikeda reaches to depths of only 100 m. According to our simple estimation, the total volume of oxygen in Lake Ikeda will reduce from approximately 70% in the mid-1980s to 40% by the end of 2010. In addition to this phenomenon, the oxygen concentration appears to vary with several years oscillations. The depths to which mixing occurs depends on the severity of the winter, such as the air temperature during the winter season. The mixing period generally occurs in February; hence, the limnological year is considered to start in February. During our analysis period, the total DO mass showed high values in 1996, 2001, and 2003. Air temperature data obtained for regions near Lake Ikeda (the station name is Ibusuki) are used to clarify the cause of the high DO mass values in the three abovementioned years. During the period prior to the occurrence of the high DO mass in February 1996, i.e., in December 1995 and January 1996, the air temperature was low. Similarly, in 2001 and 2003, the air temperature was low in January (one month before the high DO mass was observed). In January 2001 and 2003, the AO (Atlantic Oscillation) index was negative. When the AO index is negative, there tends to be a greater movement of cold polar air into mid-latitudinal regions including Japan (Yamakawa, 2005). This movement induced a low air temperature in Ibusuki, and consequently, a high DO mass

    Research on intestinal bacteria began around the end of the 19th century. During the last 5 decades of the 20th century, research on the intestinal microbiota made rapid progress. At first, in my work, I first developed a method of comprehensive analysis of the intestinal microbiota, and then I established classification and identification methods for intestinal anaerobes. Using these methods I discovered a number of ecological rules governing the intestinal microbiota and the role of the intestinl microbiota in health and disease. Moreover, using germfree animals, it was proven that the intestinal microbiota has a role in carcinogenesis and aging in the host. Thus, a new interdisciplinary field, “intestinal bacteriology” was established. PMID:25032084

    Abstract The hesionid polychaete Hesione reticulata von Marenzeller, 1879 was described from Enoshima Island, Japan and has been recorded also from the Red Sea. Depending on researchers, it has been regarded as either a distinct species or synonymous with older established ones. The type specimen has been lost. In order to clarify its taxonomic status, Hesione reticulata is herein redescribed, illustrated, and a neotype is proposed based on recent material collected near the type locality. The diagnostic features include the presence of several dorsal, discontinuous longitudinal bands, interrupted by pale segmental spots; prostomium with tiny antennae; a tuberculated dorsal integument; acicular lobes double; and neurochaetal blades with guards approaching the distal tooth. The dorsal color pattern in life enables a clear distinction from similar species such as Hesione intertexta Grube, 1878 amongst others. Mitochondrial COI barcoding sequences are deposited in the DNA Data Bank of Japan. A key to Hesione species from Japan is also included. PMID:28331407

    We have conducted animal experimentation as a highly effective technique in biological studies. Also in microbiological studies, we have used experimentation to prevent and treat many infectious diseases in humans and animals. In Japan, the 'Law for the Humane Treatment and Management of Animals', which covers the consideration of the three R principles, refinement, replacement and reduction for an international humane approach to animal experimentation came into effect in June 2006. Looking towards the straightforward operation of the law in animal experimentation, three government ministries established new basic guidelines for experimentation performed in their jurisdictional research and testing facilities. For future microbiological studies involving animals in Japan, we need to perform animal experiments according to the basic guidelines in association with overseas management systems. In this report, we discussed essential actions for the management of animal experimentation in microbiological studies in Japan.

    2014-01-01

    We examine educational differences in the intendedness of first births in Japan using data from a nationally representative survey of married women (N = 2,373). We begin by describing plausible scenarios for a negative, null, and positive educational gradient in unintended first births. In contrast to well-established results from the U.S., we find evidence of a positive educational gradient in Japan. Net of basic demographic controls, university graduates are more likely than less-educated women to report first births as unintended. This pattern is consistent with a scenario emphasizing the high opportunity costs of motherhood in countries such as Japan where growing opportunities for women in employment and other domains of public life have not been accompanied by changes in the highly asymmetric roles of men and women within the family. We discuss potential implications of this suggestive finding for other low-fertility settings. PMID:25914433

  2. The atomic hypothesis: physical consequences

    NASA Astrophysics Data System (ADS)

    Rivas, Martín

    2008-08-01

    The hypothesis that matter is made of some ultimate and indivisible objects, together with the restricted relativity principle, establishes a constraint on the kind of variables we are allowed to use for the variational description of elementary particles. We consider that the atomic hypothesis not only states the indivisibility of elementary particles, but also that these ultimate objects, if not annihilated, cannot be modified by any interaction so that all allowed states of an elementary particle are only kinematical modifications of any one of them. Therefore, an elementary particle cannot have excited states. In this way, the kinematical group of spacetime symmetries not only defines the symmetries of the system, but also the variables in terms of which the mathematical description of the elementary particles can be expressed in either the classical or the quantum mechanical description. When considering the interaction of two Dirac particles, the atomic hypothesis restricts the interaction Lagrangian to a kind of minimal coupling interaction.

    Internet use by the people with disabilities and the elderly in Japan is still low, but growing. However, the majority of web contents written in Japanese, even government sites, have very low accessibility. This paper introduces the active measures being taken in Japan to improve such conditions; consideration of a web contents accessibility guideline tailored to the unique characteristics of the Japanese language, development of a system to evaluate accessibility and implementation of actual trials.

    A board certification system for prosthodontic specialists was established in 2005 by the Japan Prosthodontic Society (JPS), significantly later than the system established by the American Board of Prosthodontics in 1947. The purpose of this study is to outline the certification system for prosthodontic specialists in Japan and discuss and evaluate its current status. In 2012, the number of board certified prosthodontic specialists was 1150 and that of mentorial specialists was 693. The number of board certified institutions was 78 and that of certified adjunct institutions was 23. Although the history of the certification system is not very long, we conclude that a well-organized system has been developed. In addition, prosthodontic departments of dental schools also play an important role in the certification system for prosthodontic specialists.

  7. Single atom electrochemical and atomic analytics

    NASA Astrophysics Data System (ADS)

    Vasudevan, Rama

    In the past decade, advances in electron and scanning-probe based microscopies have led to a wealth of imaging and spectroscopic data with atomic resolution, yielding substantial insight into local physics and chemistry in a diverse range of systems such as oxide catalysts, multiferroics, manganites, and 2D materials. However, typical analysis of atomically resolved images is limited, despite the fact that image intensities and distortions of the atoms from their idealized positions contain unique information on the physical and chemical properties inherent to the system. Here, we present approaches to data mine atomically resolved images in oxides, specifically in the hole-doped manganite La5/8Ca3/8MnO3, on epitaxial films studied by in-situ scanning tunnelling microscopy (STM). Through application of bias to the STM tip, atomic-scale electrochemistry is demonstrated on the manganite surface. STM images are then further analyzed through a suite of algorithms including 2D autocorrelations, sliding window Fourier transforms, and others, and can be combined with basic thermodynamic modelling to reveal relevant physical and chemical descriptors including segregation energies, existence and strength of atomic-scale diffusion barriers, surface energies and sub-surface chemical species identification. These approaches promise to provide tremendous insights from atomically resolved functional imaging, can provide relevant thermodynamic parameters, and auger well for use with first-principles calculations to yield quantitative atomic-level chemical identification and structure-property relations. This research was sponsored by the Division of Materials Sciences and Engineering, BES, DOE. Research was conducted at the Center for Nanophase Materials Sciences, which also provided support and is a DOE Office of Science User Facility.

    The red-eared slider turtle (Trachemys scripta elegans) was intentionally introduced from the United States to Japan as a pet in the 1950s and has become established throughout much of the country. We examined red-eared slider turtles from two localities in Japan for foreign parasitic helminths. Consequently, a total of seven species of helminths were found: two monogeneans (Neopolystoma exhamatum and Polystomoides japonicum), three digeneans (Spirorchisartericola, Spi.elegans and Telorchis clemmydis) and two nematodes (Serpinema microcephalum and Falcaustra wardi). Of these, three helminths are alien to Japan-Spi.artericola, Spi. elegans and F. wardi-which represent the first report of their presence in the red-eared slider turtle from Japan.

    In 1974, Japanese scientists developed a live attenuated varicella vaccine based on the Oka strain. The efficacy of the vaccine for the prevention of varicella has been primarily demonstrated in studies conducted in the United States following the adoption of universal immunization using the Oka strain varicella vaccine in 1996. Although the vaccine was developed by Japanese scientists, until recently, the vaccine has been administered on a voluntary basis in Japan resulting in a vaccine coverage rate of approximately 40%. Therefore, Japan initiated universal immunization using the Oka strain varicella vaccine in November 2014. Given the transition from voluntary to universal immunization in Japan, it will also be important to monitor the epidemiology of varicella and herpes zoster. The efficacy and safety of co-administration of the varicella vaccine and measles, mumps, and rubella vaccine have been demonstrated in many countries; however, there was no data from Japan. In order to adopt the practice of universal immunization using the Oka strain varicella vaccine in Japan, data demonstrating the efficacy and safety of co-administration of varicella vaccine and measles and rubella (MR) vaccine were required. Additionally, we needed to elucidate the appropriate time interval between the first and second administrations of the vaccine. It is also important to differentiate between wild type and Oka vaccine type strains in herpes zoster patient with past history of varicella vaccine. Thus, there are many factors to consider regarding the adoption of universal immunization in Japan to control varicella zoster virus (VZV) infections.

    Prevention of non-communicable diseases is more important than ever especially for the elderly to live a healthy life in the super-aged society of Japan. In 2000, the Ministry of Health, Labor and Welfare of Japan started Health Japan 21 as goal-oriented health promotion plan like Healthy People in the US and the Health of the Nation in the UK. Its second term started in 2013 with the aim of prolonging healthy life expectancy and reducing health inequalities. Improvement in both individuals' lifestyle and their social environment will help achieve the goal of the 2nd Health Japan 21. The National Health and Nutrition Survey (NHNS) is conducted every year to monitor the health and nutritional situation of the Japanese using a representative population. The NHNS data are useful for target setting and evaluation of the 2nd Health Japan 21, and the NHNS has shown an increasing trend of overweight (BMI≥25) only for male adults in the most recent 10 y. In contrast, the dietary intake survey of the NHNS shows a decreasing trend of total energy intake both in male and female adults aged 69 y old or younger, and the trend for physical activity is not well known. Thus, we need further investigations on the causes of the obesity trend in Japan.

    The infant mortality rate (IMR) and neonatal mortality rate (NMR) defined as the number of infant and newborn deaths per 1000 live births, respectively, are widely accepted as population indicators of the level of perinatal and postnatal health. Since the end of World War II, Japan has made substantial progress in reducing its IMR and NMR. This resulted from improving living standards and the provision of universal maternal and child health care (MCH) services. Okinawa, the island prefecture that is the furthest from mainland Japan, had the third highest IMR and the highest low-birth-weight rate (LBW) among all prefectures when its statistics were integrated into Japan in 1973. Even though the LBW rate in Okinawa has remained higher than the all-Japan average, Okinawa has shown a considerable improvement in IMR and NMR. The aim is to review the trends in IMR, NMR, and LBW in Japan and Okinawa and to discuss sociodemographic trends, economics, and the provision of health care services. The IMR and NMR in Okinawa decreased during that time from 14.8 to 2.4 and from 7.5 to 0.8, respectively. The LBW rate decreased until the mid-1980s, but since then it has increased to 11.5 (Okinawa) and 9.6 (Japan) in 2009. Okinawa's public health and primary health care model for infants has been very successful and may be applicable to child health in island nations of the Asia-Pacific region.

    In Japan, influenza like epidemics were described many times since Heian era. However, Spanish flu as the modern medicine invaded Japan in 1918, thus almost infected 390,000 patients died with associated pneumonia. After the discovery of influenza virus in 1933, Japan experienced pandemic influenza--Asian flu(H2N2) in 1957. After about 10 years, Hong Kong flu (H3N2) came to Japan at 1968. However, we had many reliable antibiotics but had not any antiviral drug at the early time. After year 2000, we fortunately obtained reliable three antiviral drugs such as amantadine, oseltamivir and zanamivir. Moreover, very useful rapid test kits for influenza A and B viruses were developed and used in Japan. 2009 H1N1 influenza epidemic occured in Japan after the great epidemic in Mexico and North America but elderly patient was few. With together, host conditions regarding with high risk are changing. Lessons from past several pandemic influenza are those that many issues for changing high risk conditions, viral genetic changes, developing antiviral agents, developing new useful vaccins and determinating bacterial secondary pathogens are important.

  14. Secondary Data Analysis of National Surveys in Japan Toward Improving Population Health.

    2016-01-01

    Secondary data analysis of national health surveys of the general population is a standard methodology for health metrics and evaluation; it is used to monitor trends in population health over time and benchmark the performance of health systems. In Japan, the government has established electronic databases of individual records from national surveys of the population's health. However, the number of publications based on these datasets is small considering the scale and coverage of the surveys. There appear to be two major obstacles to the secondary use of Japanese national health survey data: strict data access control under the Statistics Act and an inadequate interdisciplinary research environment for resolving methodological difficulties encountered when dealing with secondary data. The usefulness of secondary analysis of survey data is evident with examples from the author's previous studies based on vital records and the National Health and Nutrition Surveys, which showed that (i) tobacco smoking and high blood pressure are the major risk factors for adult mortality from non-communicable diseases in Japan; (ii) the decrease in mean blood pressure in Japan from the late 1980s to the early 2000s was partly attributable to the increased use of antihypertensive medication and reduced dietary salt intake; and (iii) progress in treatment coverage and control of high blood pressure is slower in Japan than in the United States and Britain. National health surveys in Japan are an invaluable asset, and findings from secondary analyses of these surveys would provide important suggestions for improving health in people around the world.

    Transfusion is believed to be the main cause of iron overload in Japan. A nationwide survey on post-transfusional iron overload subsequently led to the establishment of guidelines for iron chelation therapy in this country. To date, however, detailed clinical information on the entire iron overload population in Japan has not been fully investigated. In the present study, we obtained and studied detailed clinical information on the iron overload patient population in Japan. Of 1109 iron overload cases, 93.1% were considered to have occurred post-transfusion. There were, however, 76 cases of iron overload of unknown origin, which suggest that many clinicians in Japan may encounter some difficulty in correctly diagnosing and treating iron overload. Further clinical data were obtained for 32 cases of iron overload of unknown origin; median of serum ferritin was 1860.5 ng/mL. As occurs in post-transfusional iron overload, liver dysfunction was found to be as high as 95.7% when serum ferritin levels exceeded 1000 ng/mL in these patients. Gene mutation analysis of the iron metabolism-related genes in 27 cases of iron overload with unknown etiology revealed mutations in the gene coding hemojuvelin, transferrin receptor 2, and ferroportin; this indicates that although rare, hereditary hemochromatosis does occur in Japan.

    In Japan, the national health policy "Healthy Japan 21 (second term)" was introduced in 2013 to support prevention of lifestyle-related disease. Policy has also been recently revised on the promotion of nutrition education (shokuiku). Community-based food and nutrition actions were developed based on those policies and aimed to reinforce the linkages across the food chain, looking along its length "from field to food", including production, processing, preparation, eating and disposal. Local government is responsible for identifying the important food and nutritional problems, to devise and group effective actions on the basis of local health issues. The National Institute of Public Health (NIPH) is responsible for carrying out public health staff training on policy-based health issues. Training carried out by the NIPH, the Japan Dietetic Association and the Japan Public Health Association was designed to create an enabling environment for nutrition action. The community-based actions, including nutrition education and information, are carried out by several bodies, including local government, schools, facilities, volunteer groups, residents' associations, and commercial companies, to establish sustainable food systems promoting healthy diets. The community-empowering actions and effective cooperation are reported as good practice models in an annual white paper by the Cabinet Office. Japanese dieticians are expected to share their experiences of local nutrition improvement activities in Japan with international colleagues. Experience from elsewhere, including from Japanese dieticians working in developing countries, should also be applied on their return.

    The Nagasaki University Atomic Bomb Survivor Database, which was established in 1978 for elucidating the long-term health effects of the atomic bombing, has registered since 1970 about 120,000 atomic bomb survivors with a history of residence in Nagasaki city. Since the number of atomic bomb survivors has steadily been decreasing, prediction of future population is important for planning future epidemiologic studies, and we tried to predict the population of atomic bomb survivors in Nagasaki city from 2008 to 2030. In addition, we evaluated our estimated population comparing with the actual number from 2008 to 2011.

  18. On Earthquake Prediction in Japan

    PubMed Central

    UYEDA, Seiya

    2013-01-01

    Japan’s National Project for Earthquake Prediction has been conducted since 1965 without success. An earthquake prediction should be a short-term prediction based on observable physical phenomena or precursors. The main reason of no success is the failure to capture precursors. Most of the financial resources and manpower of the National Project have been devoted to strengthening the seismographs networks, which are not generally effective for detecting precursors since many of precursors are non-seismic. The precursor research has never been supported appropriately because the project has always been run by a group of seismologists who, in the present author’s view, are mainly interested in securing funds for seismology — on pretense of prediction. After the 1995 Kobe disaster, the project decided to give up short-term prediction and this decision has been further fortified by the 2011 M9 Tohoku Mega-quake. On top of the National Project, there are other government projects, not formally but vaguely related to earthquake prediction, that consume many orders of magnitude more funds. They are also un-interested in short-term prediction. Financially, they are giants and the National Project is a dwarf. Thus, in Japan now, there is practically no support for short-term prediction research. Recently, however, substantial progress has been made in real short-term prediction by scientists of diverse disciplines. Some promising signs are also arising even from cooperation with private sectors. PMID:24213204

    Cord blood transplantation (CBT) has increasingly been used in Japan and the annual number of CBT now exceeds 1,200. The cumulative number of CBT reached 12,853 in 2015, accounting for almost 1/3 of total CBT performed worldwide. It is true that smaller body size and lower costs, as compared to western countries, have been advantages for Japanese people in using CB as graft alternative. In addition, several novel findings regarding serious issues following CBT have been obtained, which further enhanced the use of CB. First, several mechanisms of engraftment failure following CBT other than cell dose have been reported, such as the presence of donor-specific anti-HLA antibodies or the development of hemophagocytic syndrome. Second, unique profiles of infectious complications following CBT have been reported, such as higher incidences of early bacterial infections and HHV-6 encephalitis, as compared to those following bone marrow (BM)/peripheral blood (PB) transplants. Third, the incidence of disease relapse was comparable to those following BM/PB transplants. Novel pre-transplant conditioning regimens using intravenous busulfan have been investigated with promising results being obtained to date. A recent analysis of Japanese transplant registry data revealed similar survival following CBT to HLA-matched unrelated BM/PB transplants.

    The achievement of the combustion research under microgravity depends substantially on the availability of diagnostic systems. The non-intrusive diagnostic systems are potentially applicable for providing the accurate, realistic and detailed information on momentum, mass and energy transport, complex gas phase chemistry, and phase change in the combustion field under microgravity. The non-intrusive nature of optical instruments is essential to the measurement of combustion process under microgravity which is very nervous to any perturbation. However, the implementation of the non-intrusive combustion diagnostic systems under microgravity is accompanied by several constraints. Usually, a very limited space is only available for constructing a highly sophisticated system which is so sensitive that it is easily affected by the magnitude of the gravitational force, vibration and heterogeneous field of temperature and density of the environments. The system should be properly adjusted prior to the experiment. Generally, it is quite difficult to tune the instruments during measurements. The programmed sequence of operation should also be provided. Extensive effort has been toward the development of non-intrusive diagnostic systems available for the combustion experiments under microgravity. This paper aims to describe the current art and the future strategy on the non-intrusive diagnostic systems potentially applicable to the combustion experiments under microgravity in Japan.

    Integrated circuits (semiconductors) are the key components of modern computers, communication systems, consumer electronics, and the new generations of smart machines and instruments. Japan's strong position and growing influence in the manufacture of semiconductors and systems based on them is well known and well documented. Microlithography is one the most critical elements of the semiconductor manufacturing process because it determines the minimum feature size and the functional capabilities of the semiconductor. Because it is used many times in the manufacturing sequence, the quality of the microlithography process (i.e., number of defects, control for feature size, etc.) is critical in determining the yield and cost of semiconductors and hence the competitiveness of the electronics industry. At present all volume semiconductor manufacturing is done with optical UV (ultraviolet) projection lithography, twenty-year-old photographic technology which has been and is still evolving. There are many issues that limit the technical capability and cost-effectiveness of UV lithography, and thus, alternate lithographic techniques are continuously being researched and developed. X-ray lithography, which was invented in the early 1970's, holds the promise of providing higher yields in manufacturing semiconductors by virtue of enhanced process latitude, process robustness, and resolution.

  2. Sulfide bonded atomic radii

    2017-03-01

    The bonded radius, r b(S), of the S atom, calculated for first- and second-row non-transition metal sulfide crystals and third-row transition metal sulfide molecules and crystals indicates that the radius of the sulfur atom is not fixed as traditionally assumed, but that it decreases systematically along the bond paths of the bonded atoms with decreasing bond length as observed in an earlier study of the bonded radius of the oxygen atom. When bonded to non-transition metal atoms, r b(S) decreases systematically with decreasing bond length from 1.68 Å when the S atom is bonded to the electropositive VINa atom to 1.25 Å when bonded to the more electronegative IVP atom. In the case of transition metal atoms, rb(S) likewise decreases with decreasing bond length from 1.82 Å when bonded to Cu and to 1.12 Å when bonded to Fe. As r b(S) is not fixed at a given value but varies substantially depending on the bond length and the field strength of the bonded atoms, it is apparent that sets of crystal and atomic sulfide atomic radii based on an assumed fixed radius for the sulfur atom are satisfactory in that they reproduce bond lengths, on the one hand, whereas on the other, they are unsatisfactory in that they fail to define the actual sizes of the bonded atoms determined in terms of the minima in the electron density between the atoms. As such, we urge that the crystal chemistry and the properties of sulfides be studied in terms of the bond lengths determined by adding the radii of either the atomic and crystal radii of the atoms but not in terms of existing sets of crystal and atomic radii. After all, the bond lengths were used to determine the radii that were experimentally determined, whereas the individual radii were determined on the basis of an assumed radius for the sulfur atom.

    At the beginning of the twentieth century, Japan and China, each for its own reasons, invited the famous physicist Niels Bohr to visit and give lectures. Bohr accepted their invitations and made the trip in 1937; however, the topics of his lectures in the two countries differed. In Japan, he mainly discussed quantum mechanics and philosophy, whereas in China, he focused more on atomic physics. This paper begins with a detailed review of Bohr's trip to Japan and China in 1937, followed by a discussion of the impact of each trip from the perspective of the social context. We conclude that the actual effect of Bohr's visit to China and Japan involved not only the spreading of Bohr's knowledge but also clearly hinged on the current status and social background of the recipients. Moreover, the impact of Bohr's trip to East Asia demonstrates that, as is the case for scientific exchanges at the international level, the international exchange of knowledge at the individual level is also powerful, and such individual exchange can even promote exchange on the international level.

    2001-01-01

    Internet use by physicians and patients has become very popular in Japan. Fifty percent of physicians use the Internet to search for medical and other information. Over the past year, 22% of patients used the Internet to obtain medical information. Because there are no restrictions within Japan on using Web sites to advertise medical treatment, information can be freely sent out, and over the past two or three years this practice has increased dramatically. Internet medical information provides information about illnesses and medications, and it helps improve the quality of life of patients and families. Yet, depending on the content of the information provided and the way this information is used, there is a potential negative side as well. On principle, users are responsible for the way information is used, but there is a need for information providers to consider users safety and to make the information effective for use. Because there is no absolute standard for evaluating the value of medical information, it is necessary to establish a system that opens a dialogue with society and that continuously accumulates high-quality information through the collection of various evaluations, rather than rely on an established authority. For industries and organizations related to commercial pursuits, in particular, it is most effective to establish their own codes for ethical conduct, rather than rely on governmental regulations. At the same time, it is important to have a confirmation function to evaluate how goals set by the outside are being implemented. Aiming at establishing a framework for the Internet medical usage, the Japan Internet Medical Association (JIMA) was founded in 1998 by medical professionals, lawyers, researchers, consumer representatives, patients and their families. We propose a system that would combine feedback from users, who would take on the role of evaluators of the implementation of an ethical code, with a displayed mark that verifies the

  5. Doping Scheme in Atomic Chain Electronics

    NASA Technical Reports Server (NTRS)

    Toshishige, Yamada

    1997-01-01

    Due to the dramatic reduction in MOS size, there appear many unwanted effects. In these small devices, the number of dopant atoms in the channel is not macroscopic and electrons may suffer significantly different scattering from device to device since the spatial distribution of dopant atoms is no longer regarded as continuous. This prohibits integration, while it is impossible to control such dopant positions within atomic scale. A fundamental solution is to create electronics with simple but atomically precise structures, which could be fabricated with recent atom manipulation technology. All the constituent atoms are placed as planned, and then the device characteristics are deviation-free, which is mandatory for integration. Atomic chain electronics belongs to this category. Foreign atom chains or arrays form devices, and they are placed on the atomically flat substrate surface. We can design the band structure and the resultant Fermi energy of these structures by manipulating the lattice constant. Using the tight-binding theory with universal parameters, it has been predicted that isolated Si chains and arrays are metallic, Mg chains are insulating, and Mg arrays have metallic and insulating phases [1]. The transport properties along a metallic chain have been studied, emphasizing the role of the contact to electrodes [2]. For electronic applications, it is essential to establish a method to dope a semiconducting chain, which is to control the Fermi energy position without altering the original band structure. If we replace some of the chain atoms with dopant atoms randomly, the electrons will see random potential along die chain and will be localized strongly in space (Anderson localization). However, if we replace periodically, although the electrons can spread over the chain, there will generally appear new bands and band gaps reflecting the new periodicity of dopant atoms. This will change the original band structure significantly. In order to overcome

  6. Establishing maintenance performance indicators

    Baca, B.

    1994-10-01

    Maintenance Performance Indicators (PI) specify where the maintenance department is and which direction it is going allowing for a quick and accurate assessment of the performance of the Maintenance Management Program (MMP). Establishing PI`s for the maintenance department will allow a measure of productivity and a means of feedback for methods improvement. Effective performance of the maintenance department directly effects plant profitability. Improvements in the quality and productivity of the maintenance work force will significantly reduce maintenance costs. The level of performance attained by the maintenance work force is usually guessed at. Guessing will not identify areas needing improvement or help to initiate a corrective action. Maintenance PI`s are required for maintenance departments whose goal is to control maintenance costs while increasing productivity. The application of basic statistical methods will allow a maintenance department to know where they are and which direction they are going. The data presented in this paper is a representation of indicators used in industry as well as developed indicators to establish a complete maintenance performance indicator program. The methodology used in developing this program can be used as a way to manage a cost effective maintenance management program.

It aimed to demonstrate capability of state-of-the-art theoretical techniques to explain and predict ELNES and XANES spectra, and to allow deep discussion between scientists in the two communities. It also provided an excellent opportunity to introduce experimentalists to the computational techniques available. Invited talks and poster presentations by leading scientists were given on the first day, which was followed by tutorial sessions for five computer programs on the second and third days. Excellent lectures were given by Peter Blaha (Vienna, Austria) on the WIEN2k code, Chris J Pickard (St Andrews, UK) on the CASTEP code, John J Rehr (Seattle, USA) on the FEFF8 code, Frank de Groot (Utrecht, The Netherlands) on the CTM4XAS code, and Hidekazu Ikeno (Kyoto, Japan) on the first-principles CI-multiplet code. Thanks to the enthusiastic participation of more than 100 scientists from around the world, the workshop was a complete success. The aim of this special issue in Journal of Physics: Condensed Matter is to share with the readers the most up-to-date knowledge presented at the workshop. We believe this will prove useful as a reference for researchers in many different fields, as well as an overview of the current status and future directions of theoretical calculations for ELNES and XANES.

    Most personal computers (PCs) are discarded by consumers after the data files have been moved to a new PC. Therefore, a used PC collection scheme should be created that does not depend on the distribution route of new PCs. In Japan, manufacturers' voluntary take-back recycling schemes were established in 2001 (for business PCs) and 2003 (for household PCs). At the same time, the export of used PCs from Japan increased, affecting the domestic PC reuse market. These regulatory and economic conditions would have changed the flow of used PCs. In this paper, we developed a method of minimizing the errors in estimating the material flow of used PCs. The method's features include utilization of both input and output flow data and elimination of subjective estimation as much as possible. Flow rate data from existing surveys were used for estimating the flow of used PCs in Japan for fiscal years (FY) 2000, 2001, and 2004. The results show that 3.92 million and 4.88 million used PCs were discarded in FY 2000 and 2001, respectively. Approximately two-thirds of the discarded PCs were disposed of or recycled within the country, one-fourth was reused within the country, and 8% were exported. In FY 2004, 7.47 million used PCs were discarded. The ratio of domestic disposal and recycling decreased to 37% in FY 2004, whereas the domestic reuse and export ratios increased to 37% and 26%, respectively. Flows from businesses to retailers in FY 2004 increased dramatically, which led to increased domestic reuse. An increase in the flow of used PCs from lease and rental companies to secondhand shops has led to increased exports. Results of interviews with members of PC reuse companies were and trade statistics were used to verify the results of our estimation of domestic reuse and export of used PCs.

  11. Reconsidering Japan's underperformance in pharmaceuticals: evidence from Japan's anticancer drug sector.

    Unlike its automobile or electronics industries, Japan's pharmaceutical industry did not become a global leader. Japan remains a net importer of pharmaceuticals and has introduced few global blockbuster drugs. Alfred Chandler argued that Japan's pharmaceutical firms remained relatively weak because Western firms enjoyed an insurmountable first first-mover advantage. However, this case study of the anticancer drug sector illustrates that Chandler's explanation is incomplete. Japanese medical culture, government policy, and research environment also played a substantial role in shaping the industry. In the 1970s and 1980s, these factors encouraged firms to develop little few effective drugs with low side effects, and profit from Japan's domestic market. But, these drugs were unsuitable to foreign markets with more demanding efficacy standards. As a result, Japan not only lost more than a decade in developing ineffective drugs, but also neglected to create the infrastructure necessary to develop innovative drugs and build a stronger pharmaceutical industry.

  12. Establishing Substantial Equivalence: Transcriptomics

    Baudo, María Marcela; Powers, Stephen J.; Mitchell, Rowan A. C.; Shewry, Peter R.

    Regulatory authorities in Western Europe require transgenic crops to be substantially equivalent to conventionally bred forms if they are to be approved for commercial production. One way to establish substantial equivalence is to compare the transcript profiles of developing grain and other tissues of transgenic and conventionally bred lines, in order to identify any unintended effects of the transformation process. We present detailed protocols for transcriptomic comparisons of developing wheat grain and leaf material, and illustrate their use by reference to our own studies of lines transformed to express additional gluten protein genes controlled by their own endosperm-specific promoters. The results show that the transgenes present in these lines (which included those encoding marker genes) did not have any significant unpredicted effects on the expression of endogenous genes and that the transgenic plants were therefore substantially equivalent to the corresponding parental lines.

    The basis for this successful collaboration was face-to-face communication. Though it was sometimes stressful being on the road so much, I really learned the importance of being present to work together and ask questions in person. Another measure of success was that in the midst of this project and traveling, my wife and I managed to start a family. My oldest boy got a real kick out of visiting Space Center Houston when he was two to learn all about the "face futtle" which goes way up in the sky. When practical, collocation and face-to-face communication on a project eliminate misunderstandings, establish relationships, make information more easily accessible, and promote a team atmosphere. Compromise is key to balancing both family and career goals. Knowing when to prioritize each is important to success in both aspects.

    Lumsden, J H; Mullen, K

    1978-01-01

    In order to establish a range of reference values for any characteristic one can use Gaussian or nonparametric techniques, whichever are most appropriate. One has the choice of calculating tolerance intervals or percentile intervals. A tolerance interval is said to contain, say 95% of the population with probability, say 0.90. A percentile interval simply simply calculates the values between which 95% of the observations fall. If the data can be said to have a Gaussian distribution, the same precision can be obtained with smaller sample sizes than using the nonparametric techniques. In some cases, data which are not Gaussian can be transformed into a Gaussian form and hence make use of the more efficient Gaussian techniques. In both cases, the data should be checked for outliers or rogue observations and these should be eliminated if the testing procedure fails to imply that they are an integral part of the data.

    2007-09-01

    Graphite filter atomizers (GFA) for electrothermal atomic absorption spectrometry (ETAAS) show substantial advantages over commonly employed electrothermal vaporizers and atomizers, tube and platform furnaces, for direct determination of high and medium volatility elements in matrices associated with strong spectral and chemical interferences. Two factors provide lower limits of detection and shorter determination cycles with the GFA: the vaporization area in the GFA is separated from the absorption volume by a porous graphite partition; the sample is distributed over a large surface of a collector in the vaporization area. These factors convert the GFA into an efficient chemical reactor. The research concerning the GFA concept, technique and analytical methodology, carried out mainly in the author's laboratory in Russia and South Africa, is reviewed. Examples of analytical applications of the GFA in AAS for analysis of organic liquids and slurries, bio-samples and food products are given. Future prospects for the GFA are discussed in connection with analyses by fast multi-element AAS.

    Condensation processes are of key importance in nature and play a fundamental role in chemistry and physics. Owing to size effects at the nanoscale, it is conceptually desired to experimentally probe the dependence of condensate structure on the number of constituents one by one. Here we present an approach to study a condensation process atom-by-atom with the scanning tunnelling microscope, which provides a direct real-space access with atomic precision to the aggregates formed in atomically defined 'quantum boxes'. Our analysis reveals the subtle interplay of competing directional and nondirectional interactions in the emergence of structure and provides unprecedented input for the structural comparison with quantum mechanical models. This approach focuses on-but is not limited to-the model case of xenon condensation and goes significantly beyond the well-established statistical size analysis of clusters in atomic or molecular beams by mass spectrometry.

As an example, we develop and implement perturbation theory to compute the polarizability of an atom in an experimentally relevant situation.

    10Be concentrations of six Red soils distributed in Southwest Japan ranged from 0.8 × 108 to 2.7 × 109 atoms g-1, and minimum absolute ages were estimated by inventory of meteoric 10Be. The results are follows: Red soils on Toyota derived from granite (⩽25 ka), Kashii derived from Tertiary shale (⩽24 ka), Akiyoshidai derived from limestone (⩽110 ka), Okinawa Island derived from Kunigami gravel bed (⩽9 ka) and Ogasawara Island derived from agglomerate and Boninite (⩽22 and ⩽7 ka) were obtained, respectively. Soil age except with Akiyoshidai indicated younger age. It suggested that the loss of 10Be from the soil was caused by leaching of 10Be or by soil erosion, and 10Be is susceptible to leaching out from these Red soils under the humid climate condition such as Southwest Japan.

The atomizer may be elongated along its axis to increase the distance between the optical path and the sample deposition point. Also, the atomizer may be elongated along the axis of the optical path, whereby its analytical sensitivity is greatly increased.

    In the consumer electronics industry, precision processing technology is the basis for enhancing product functions and for minimizing components and end products. Throughout Japan, manufacturing technology is seen as critical to the production and assembly of advanced products. While its population has increased less than 30 percent over twenty-five years, Japan's gross national product has increase thirtyfold; this growth has resulted in large part from rapid replacement of manual operations with innovative, high-speed, large-scale, continuously running, complex machines that process a growing number of miniaturized components. The JTEC panel found that introduction of next-generation electronics products in Japan goes hand-in-hand with introduction of new and improved production equipment. In the panel's judgment, Japan's advanced process technologies and equipment development and its highly automated factories are crucial elements of its domination of the consumer electronics marketplace - and Japan's expertise in manufacturing consumer electronics products gives it potentially unapproachable process expertise in all electronics markets.

  8. Cenozoic rift tectonics of the Japan Sea

    SciTech Connect

    Kimura, K.

    1988-08-01

    The Japan Sea is one of the back-arc basins in trench-arc systems bordering the western Pacific. Recent paleomagnetic works suggest the Japan Sea opened during early to middle Miocene. Radiometric and microfossil ages of the Cenozoic onland sequences in the Japanese Islands elucidate the rift tectonics of the Japan Sea. The rifting history is summarized as follows: nonmarine volcanic formations of prerift stage before 50 Ma, rift-onset unconformity at 40 Ma, nonmarine volcanic formations of synrift stage 20-33 Ma, breakup unconformity 19 Ma showing the opening of the Japan Sea, marine volcanic and sedimentary formations of synrift stage 14.5-18 Ma, beginning of regional subsidence 14.5 Ma corresponding to the end of the Japan Sea opening, marine sedimentary formations of postdrift stage after 14.5 Ma. Rifting is not limited to the synrift stage but is continued to the syndrift stage. Rifting led to a horst-and-graben structure. Thus, the Cenozoic onland sequences in the Japanese Islands are suited for a study of rift tectonics because the sequences were subaerially exposed by the late Miocene-Holocene island-arc tectonics. Rift tectonics cannot be studied as easily in most Atlantic-type passive margins.

    Atomic and single-molecule junctions represent the ultimate limit to the miniaturization of electrical circuits. They are also ideal platforms for testing quantum transport theories that are required to describe charge and energy transfer in novel functional nanometre-scale devices. Recent work has successfully probed electric and thermoelectric phenomena in atomic-scale junctions. However, heat dissipation and transport in atomic-scale devices remain poorly characterized owing to experimental challenges. Here we use custom-fabricated scanning probes with integrated nanoscale thermocouples to investigate heat dissipation in the electrodes of single-molecule ('molecular') junctions. We find that if the junctions have transmission characteristics that are strongly energy dependent, this heat dissipation is asymmetric--that is, unequal between the electrodes--and also dependent on both the bias polarity and the identity of the majority charge carriers (electrons versus holes). In contrast, junctions consisting of only a few gold atoms ('atomic junctions') whose transmission characteristics show weak energy dependence do not exhibit appreciable asymmetry. Our results unambiguously relate the electronic transmission characteristics of atomic-scale junctions to their heat dissipation properties, establishing a framework for understanding heat dissipation in a range of mesoscopic systems where transport is elastic--that is, without exchange of energy in the contact region. We anticipate that the techniques established here will enable the study of Peltier effects at the atomic scale, a field that has been barely explored experimentally despite interesting theoretical predictions. Furthermore, the experimental advances described here are also expected to enable the study of heat transport in atomic and molecular junctions--an important and challenging scientific and technological goal that has remained elusive.

    1999-11-01

    The transition state is fundamental to modern theories of reaction dynamics: essentially, the transition state is a structure in phase space that all reactive trajectories must cross. While transition-state theory (TST) has been used mainly in chemical physics, it is possible to apply the theory to considerable advantage in any collision problem that involves some form of reaction. Of special interest are systems in which chaotic scattering or half-scattering occurs such as the ionization of Rydberg atoms in external fields. In this paper the ionization dynamics of a hydrogen atom in crossed electric and magnetic fields are shown to possess a transition state: We compute the periodic orbit dividing surface (PODS) which is found not to be a dividing surface when projected into configuration space. Although the possibility of a PODS occurring in phase space rather than configuration space has been recognized before, to our knowledge this is the first actual example: its origin is traced directly to the presence of velocity-dependent terms in the Hamiltonian. Our findings establish TST as the method of choice for understanding ionization of Rydberg atoms in the presence of velocity-dependent forces. To demonstrate this TST is used to (i) uncover a multiple-scattering mechanism for ionization and (ii) compute ionization rates. In the process we also develop a method of computing surfaces of section that uses periodic orbits to define the surface, and examine the fractal nature of the dynamics.

    PubMed

    Fox, Michael J; Touri, Behrouz; Shamma, Jeff S

    2015-07-07

    We study an atomic signaling game under stochastic evolutionary dynamics. There are a finite number of players who repeatedly update from a finite number of available languages/signaling strategies. Players imitate the most fit agents with high probability or mutate with low probability. We analyze the long-run distribution of states and show that, for sufficiently small mutation probability, its support is limited to efficient communication systems. We find that this behavior is insensitive to the particular choice of evolutionary dynamic, a property that is due to the game having a potential structure with a potential function corresponding to average fitness. Consequently, the model supports conclusions similar to those found in the literature on language competition. That is, we show that efficient languages eventually predominate the society while reproducing the empirical phenomenon of linguistic drift. The emergence of efficiency in the atomic case can be contrasted with results for non-atomic signaling games that establish the non-negligible possibility of convergence, under replicator dynamics, to states of unbounded efficiency loss.

However, the majority of the literature comprises retrospective single-center studies collecting data on small numbers of patients. Several multi-center studies are ongoing in Japan; however, the current data are insufficient for comprehensively outlining the various characteristics of MMD. To enhance our knowledge on epidemiologic, vascular, and genetic aspects of MMD, a prospective multicenter registry will be established in Japan that will help to streamline clinical research as well as improve clinical treatments and long-term outcomes. Patients with MMD or secondary moyamoya syndrome referred to the participating centers will be invited to the registry. Demographic and physiological parameters, along with neuroimaging data will be collected chronologically. Clinical events, including neurological, medical, and surgical interventions will be recorded. Whole blood samples will be collected. Extra- and intracranial vascular tissue, and/or cerebrospinal fluid will also be collected from patients who undergo surgical revascularization. These biospecimens will be stored at the repositories and utilized for genome-wide association studies for identifying genetic variants, as well as tissue-specific proteomic, and/or molecular analyses. Ethics approval will be obtained at all facilities collecting biospecimens. The registry will provide descriptive statistics on functional outcomes, surgical techniques used, medications, and neurological events stratified according to patients’ clinical characteristics.

    Human have struggled against many infectious diseases such as cholera, plague, dysentery and yellow fever for a long time. And we have spent a lot of energy to control these infectious diseases and developed various tool for them. One of these efforts was Quarantine system that was established in 14th century in Europe. But during recent days, we are suffering from newly emerged diseases. These new infectious diseases are zoonosis and most of them are serious and highly infectious. Viral hemorrhagic fever such as Ebola hemorrhagic fever, Marburg hemorrhagic fever and Lassa fever are typical these emerging serious diseases, and these outbreak always have occurred in Africa and neighboring countries. Fortunately we have never experienced any case, but as these diseases are so serious, we are so nervous diseases entering in Japan. Against these serious diseases, in Japan, Quarantine Station are doing screening examination at airport and port by questionnaire and measuring body temperature, because these viral hemorrhagic fever patients show high fever. If people were suspected viral hemorrhagic fever at Quarantine Station at the border, they will be leaded to hospital for further examination and treatment as soon as possible.

    With the expansion of novel chromosome testing, a career as a certified genetic counselor has been gathering a lot of attention. However, few people certified as a genetic counselor after completing postgraduate courses are able to find employment as a genetic counselor, and their salaries are quite low. It is also questionable whether or not such newly graduated genetic counselors, who have limited life experience and knowledge, can fully understand family issues and properly perform counseling sessions. To address these issues, a wide range of education and training may be necessary. In this study, we examined current problems in genetic counseling education in Japan, and proposed effective measures to address these problems. Toward creating a new society, we are currently establishing a national qualification system and cultivating qualified professionals capable of providing patients with accurate information on chromosome and genetic testing. In addition, these professionals could encourage younger generations to have an interest in genetic counseling. I also hope that these professionals will work not only in Japan but all over the world.

    Recent research has highlighted the potential of lunar resources as an important element of space exploration but their viability has not been demonstrated. Establishing whether or not they can be considered in future plans is a multidisciplinary effort, requiring scientific expertise and delivering scientific results. To this end various space agencies and private entities are looking to lunar resources, extracted and processed in situ, as a potentially game changing element in future space architectures, with the potential to increase scale and reduce cost. However, before any decisions can be made on the inclusion of resources in exploration roadmaps or future scenarios some big questions need to be answered about the viability of different resource deposits and the processes for extraction and utilisation. The missions and measurements that will be required to answer these questions, and which are being prepared by agencies and others, can only be performed through the engagement and support of the science community. In answering questions about resources, data and knowledge will be generated that is of fundamental scientific importance. In supporting resource prospecting missions the science community will de facto generate new scientific knowledge. Science enables exploration and exploration enables science.

    This innovation enables a means for actively measuring atomic oxygen fluence (accumulated atoms of atomic oxygen per area) that has impinged upon spacecraft surfaces. Telemetered data from the device provides spacecraft designers, researchers, and mission managers with real-time measurement of atomic oxygen fluence, which is useful for prediction of the durability of spacecraft materials and components. The innovation is a compact fluence measuring device that allows in-space measurement and transmittance of measured atomic oxygen fluence as a function of time based on atomic oxygen erosion yields (the erosion yield of a material is the volume of material that is oxidized per incident oxygen atom) of materials that have been measured in low Earth orbit. It has a linear electrical response to atomic oxygen fluence, and is capable of measuring high atomic oxygen fluences (up to >10(exp 22) atoms/sq cm), which are representative of multi-year low-Earth orbital missions (such as the International Space Station). The durability or remaining structural lifetime of solar arrays that consist of polymer blankets on which the solar cells are attached can be predicted if one knows the atomic oxygen fluence that the solar array blanket has been exposed to. In addition, numerous organizations that launch space experiments into low-Earth orbit want to know the accumulated atomic oxygen fluence that their materials or components have been exposed to. The device is based on the erosion yield of pyrolytic graphite. It uses two 12deg inclined wedges of graphite that are over a grit-blasted fused silica window covering a photodiode. As the wedges erode, a greater area of solar illumination reaches the photodiode. A reference photodiode is also used that receives unobstructed solar illumination and is oriented in the same direction as the pyrolytic graphite covered photodiode. The short-circuit current from the photodiodes is measured and either sent to an onboard data logger, or

    2008-09-01

    A research project at the "Laboratoire d'électronique quantique" consists in a theoretical study of the reflection and diffraction phenomena via an atomic mirror. This poster presents the principle of an atomic mirror. Many groups in the world have constructed this type of atom optics experiments such as in Paris-Orsay-Villetaneuse (France), Stanford-Gaithersburg (USA), Munich-Heidelberg (Germany), etc. A laser beam goes into a prism with an incidence bigger than the critical incidence. It undergoes a total reflection on the plane face of the prism and then exits. The transmitted resulting wave out of the prism is evanescent and repulsive as the frequency detuning of the laser beam compared to the atomic transition δ = ωL-ω0 is positive. The cold atomic sample interacts with this evanescent wave and undergoes one or more elastic bounces by passing into backward points in its trajectory because the atoms' kinetic energy (of the order of the μeV) is less than the maximum of the dipolar potential barrier ℏΩ2/Δ where Ω is the Rabi frequency [1]. In fact, the atoms are cooled and captured in a magneto-optical trap placed at a distance of the order of the cm above the prism surface. The dipolar potential with which interact the slow atoms is obtained for a two level atom in a case of a dipolar electric transition (D2 Rubidium transition at a wavelength of 780nm delivered by a Titane-Saphir laser between a fundamental state Jf = l/2 and an excited state Je = 3/2). This potential is corrected by an attractive Van der Waals term which varies as 1/z3 in the Lennard-Jones approximation (typical atomic distance of the order of λ0/2π where λ0 is the laser wavelength) and in 1/z4 if the distance between the atom and its image in the dielectric is big in front of λ0/2π. This last case is obtained in a quantum electrodynamic calculation by taking into account an orthornormal base [2]. We'll examine the role of spontaneous emission for which the rate is inversely

  20. Electron - Atom Bremsstrahlung

    NASA Astrophysics Data System (ADS)

    Kim, Longhuan

    In this work we study the features of bremsstrahlung radiation from neutral atoms and atoms in hot dense plasmas. Predictions for the distributions of electron-atom bremsstrahlung radiation for both the point Coulomb potential and screened potentials are obtained using a classical numerical method. The results agree with exact quantum mechanical partial wave results for low incident electron energies in both the point Coulomb and screened potentials. In the screened potential the asymmetry parameter of a spectrum is reduced from the Coulomb values. The difference increases with decreasing energy and begins to oscillate at very low energies. We also studied the scaling properties of bremsstrahlung spectra and energy losses. It is found that the ratio of the radiative energy loss for positrons to that for electrons obeys a simple scaling law, being expressible fairly accurately as a function only of the quantity T(,1)/Z('2). This scaling is exact in the case of the point Coulomb potential, both for classical bremsstrahlung and for the nonrelativistic dipole Sommerfeld formula. We also studied bremsstrahlung from atoms in hot dense plasmas, describing the atomic potentials by the temperature-and-density dependent Thomas - Fermi model. Gaunt factors are obtained with the relativistic partial wave method for atoms in plasmas of various densities and temperatures. Features of the bremsstrahlung from atoms in such environments are discussed. The dependence of predicted bremsstrahlung spectra on the choice of potential from various average atom potential models for strongly coupled plasmas are also studied. For the energy range and plasma densities were considered, the choice of potential model among the elaborate atomic potentials is less important than the choice of the method of calculation. The use of a detailed configuration accounting method for bremsstrahlung processes in dense plasmas is less important than for some other atomic processes. We justify the usefulness

    Pine wilt disease induced by the pinewood nematode, Bursaphelenchus xylophilus, is a great threat to pine forests in Japan. The first occurrence of the disease was reported in Nagasaki, Kyushu. During the 1930s the disease occurrence was extended in 12 prefectures, and in the 1940s the disease was found in 34 prefectures. The annual loss of pine trees increased from 30,000 m(3) to 1.2 million m(3) during these two decades. The enormous increase in timber loss in the 1970s resulted in 2.4 million m(3) of annual loss in 1979. The affected area expanded into 45 prefectures of 47 prefectures in Japan. In cool areas the disease differs in epidemiology from that in heavily infested areas in the warm regions. A national project for controlling pine wilt disease lays special emphasis on the healthy pine forests predominating throughout cool areas in northern Japan.

    The incidence of mushroom poisoning was studied statistically from 2001 to 2010 in Japan. The total incident of mushroom poisoning was 569 cases, which involved 1,920 patients and 10 deaths. The average incident was 56.9 cases per year, involving 192 patients and 1 death. On regional differences, the mushroom poisoning was more frequent in the northeastern part of Japan. The rate of total incidents for each type of poisoning, which were classified according to symptoms caused, 54.6% in the type of gastro-intestinal disorder, 11.6% in the type of neurological symptoms, and 2.4% in the type of intracellular disorder (violent vomiting, diarrhea and dehydration and hepato-nephrosis, or rhabdomyolysis, or erroneous perception, etc.), respectively. Two species of poisonous mushrooms with gastro-intestinal disorder, Lampteromyces japonicus and Rhodophyllus rhodopolius caused the majority (52%) of all poisonings in Japan.

    Japan has experienced many major earthquake disasters in the past. Early in this century research began that was aimed at predicting the occurrence of earthquakes, and in 1965 an earthquake prediction program was started as a national project. In 1978 a program for constant monitoring and assessment was formally inaugurated with the goal of forecasting the major earthquake that is expected to occur in the near future in the Tokai district of central Honshu Island. The issue of predicting the anticipated Tokai earthquake is discussed in this article as well as the results of research on major recent earthquakes in Japan-the Izu earthquakes (1978 and 1980) and the Japan Sea earthquake (1983).

    There were many interesting presentations of unique studies at the Annual Meeting of the Japanese Society of Nuclear Medicine, although there were fewer attendees from Europe than expected. These presentations included research on diseases that are more frequent in Japan and Asia than in Europe, synthesis of original radiopharmaceuticals, and development of imaging devices and methods with novel ideas especially by Japanese manufacturers. In this review, we introduce recent nuclear medicine research conducted in Japan in the five categories of Oncology, Neurology, Cardiology, Radiopharmaceuticals and Technology. It is our hope that this article will encourage the participation of researchers from all over the world, in particular from Europe, in scientific meetings on nuclear medicine held in Japan.

    The intraaortic balloon pumping (IABP) is the most widely used circulatory assist device. IABP increases coronary perfusion in diastolic phase by the inflation of the balloon in the descending aorta (diastolic augmentation) and reduces afterload in systolic phase by the deflation of the balloon( systolic unloading). IABP improves the hemodynamic condition of patients who fall into acute heart failure and/or cardiogenic shock. Six-type IABP system can be used in Japan. The IABP-SHOCK II trial shows that there is no significant difference in mortality between optimal medical treatment with IABP and without IABP in addition to early revascularization. Clinical backgrounds in Japan are different from those in IABP-SHOCK II trial, and the further prospective studies of IABP in Japan thus called for.

    The interdependence of the U.S.-Japanese economies makes it imperative that we in the United States understand how business and technology developments take place in Japan. We can gain insight into these developments in software engineering by studying the context in which Japanese software is developed, the practices that are used, the problems encountered, the setting surrounding these problems, and the resolution of these problems. Context includes the technological and sociological characteristics of the software development environment, the software processes applied, personnel involved in the development process, and the corporate and social culture surrounding the development. Presented in this paper is a summary of results of a study that addresses these issues. Data for this study was collected during a three month visit to Japan where the author interviewed 20 software managers representing nine companies involved in developing software in Japan. These data are compared to similar data from the United States in which 12 managers from five companies were interviewed.

  9. The difference in gastric cancer between Japan, USA and Europe: what are the facts? what are the suggestions?

    2001-10-01

    In Japan the survival rate for gastric cancer has steadily improved over the last 30 years whilst that in the West has remained static and inferior. In this review three hypotheses are examined to explain the difference. There is little evidence to suggest genetic differences, which might result in a less aggressive cancer in Japan. Recently there has been a rise in the proportion of cancers of the gastro-oesophageal junction in the West and this has not been seen in Japan. The comparison of survival data from these two regions is problematic with different staging systems and a stage migration effect. The established surgical treatment of gastric cancer in Japan is radical gastrectomy and regional lymphadenectomy and this has been proposed as a superior treatment to the standard gastrectomy common in the West. The results for survival benefit however, have not been reproduced in randomized clinical trials. The heterogeneity of adjuvant and neoadjuvant treatment regimens in Japan and the West has led to difficulties in the interpretation of their effects. There is considerable scope for future collaboration between clinicians in the West and Japan.

    To determine the status of biosafety in clinical laboratories in Japan, we conducted a survey using questionnaires on the biosafety of laboratory personnel in 2004. We obtained data from 431 hospitals (response: 59.5%). Respondents were 301 institutions (70%) having biological safety cabinets (BSCs). BSCs were held in 78% of microbiological laboratories, 7.9% of genetic laboratories, 2.7% of histopathological laboratories, and 1% or less at other laboratories. A clean bench in examination rooms for acid-fast bacilli was applied at 20 hospitals. We found 28 cases of possible laboratory-associated tuberculosis infection, 25 of which were associated with lack of BSC. Other risk factors were immature skills and insufficiently skilled eguipment operation. The frequency of rupture accidents during specimen centrifugation was 67% in dealing with blood and 9.7% in collecting acid-fast bacilli. Half or more accidents were related to inadequate sample tube materials. Technologists were shown to be working on blood collection in many hospitals (75%), and 1,534 events of self-inflicted needle puncture developed in the last 5 years. These results suggest that biosafety systems are woefully lacking or inadequate in clinical laboratories in Japan and must be established at the earliest possible opportunity.

    The atom sets an ultimate scaling limit to Moore's law in the electronics industry. While electronics research already explores atomic scales devices, photonics research still deals with devices at the micrometer scale. Here we demonstrate that photonic scaling, similar to electronics, is only limited by the atom. More precisely, we introduce an electrically controlled plasmonic switch operating at the atomic scale. The switch allows for fast and reproducible switching by means of the relocation of an individual or, at most, a few atoms in a plasmonic cavity. Depending on the location of the atom either of two distinct plasmonic cavity resonance states are supported. Experimental results show reversible digital optical switching with an extinction ratio of 9.2 dB and operation at room temperature up to MHz with femtojoule (fJ) power consumption for a single switch operation. This demonstration of an integrated quantum device allowing to control photons at the atomic level opens intriguing perspectives for a fully integrated and highly scalable chip platform, a platform where optics, electronics, and memory may be controlled at the single-atom level.

  18. Neutral atom lithography with metastable helium

    NASA Astrophysics Data System (ADS)

    Allred, Claire Shean

    In this dissertation we describe our performance of resist assisted neutral atom lithography using a bright beam of metastable 23S1 Helium (He*). Metastable Helium atoms have 20 eV of internal energy making them easy to detect and able to destroy a resist. The He* is produced by a reverse flow DC discharge source and then collimated with the bichromatic force, followed by three optical molasses velocity compression stages. The atoms in the resulting beam have a mean longitudinal velocity of 1125 m/s and a divergence of 1.1 mrad. The typical beam flux is 2 x 109 atoms/mm2s through a 0.1mm diameter aperture 70 cm away from the source. The internal energy of the atoms damages the molecules of a self assembled monolayer (SAM) of nonanethiol. The undisturbed SAM protects a 200 A layer of gold that has been evaporated onto a prepared Silicon wafer from a wet chemical etch. Two methods are used to pattern the He* atoms before they destroy the SAM. First, a Nickel micro mesh was used to protect the SAM. These experiments established an appropriate dosage and etch time for patterning. The samples were analyzed with an atomic force microscope and found to have an edge resolution of 63 nm. Then, patterning was accomplished using the dipole force the atoms experience while traversing a standing wave of lambda = 1083nm light tuned 500MHz below the 23S 1 → 23P2 transition. Depending on the intensity of the light, the He* atoms are focused or channeled into lines separated by lambda/2. The lines cover the entire exposed length of the substrate, about 3 mm. They are about 3 mm long, corresponding to about twice the beam waist of the laser standing wave. Thus there are 6 x 10 3 lines of length 5500lambda. These results agree with our numerical simulations of the experiment.

    The voyage of the Mexican commission to observe the transit of Venus on 8 December 1874 in Japan is briefly recounted. The five-man expedition was led by Francisco Díaz Covarrubias. They succeeded in establishing two observing stations near Yokohama, one in Nogue-no-Yama and one on a hill called "The Bluff", and also in determining precise geographical positions for them. Clear skies allowed the observation of the transit at both stations. The results were presented in Paris in 1875, and published on the same year. They were meant as a contribution to be processed along with all other data obtained by different missions. The importance of the expedition for the development of early modern science in Mexico - particularly astronomy - is examined in the broad context of the social and political conditions then prevailing in the country. The relevance of the mission for the establishment of scientific, cultural and even commercial ties between Japan and Mexico is emphasized.

    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

  2. Atom Recombination on Surface

    NASA Astrophysics Data System (ADS)

    Kim, Young Chai

    Upon high speed re-entry of the Space Shuttle Orbiter (SSO) through the earth's atmosphere, oxygen and nitrogen atoms produced in the shock wave in front of the SSO recombine on the surface of the SSO, releasing heat. To minimize the rise of surface temperature due to the reaction, surface material of the SSO should have a low recombination probability, gamma, of atoms impinging on it. To design such material, it is necessary to understand the mechanism of atom recombination. With this in mind, gamma values were measured for recombination of O, N, and H atoms in a diffusion tube reactor between 700 and 1250 K (HT), 300 and 700 K (MT), and at 194 K (LT) on silica. The rate of recombination was first order with respect to the atom concentration from LT to HT. The Arrhenius plots, gamma vs. 1/T, were very complex. All observations are explained by assuming a surface with a small fraction of active sites that irreversibly bind chemisorbed atoms. Everything happens as if the active sites were surrounded by collection zones within which all atoms striking the surface are adsorbed reversibly with an assumed sticking probability of unity. These atoms then diffuse on the surface. Some of them reach the active sites where they can recombine with the chemisorbed atoms. At LT, all atoms striking the surface reach the active sites. As a result of desorption at MT, the collection zones shrink with increasing temperature. At HT, only atoms striking active sites directly from the gas phase lead to recombination. An analytical solution of the diffusion-reaction problem obtained for a model where the active sites are distributed uniformly fits with the experimental data from LT to HT. The two novel features of this work are the identification of the active sites on silica for recombination of H on silica at HT as surface OH groups and the suggestion that another kind of active site is responsible for recombination of O and N atoms at HT as well as for H atoms at LT and MT.

    An experimental investigation was performed to quantify the characteristics of the sprays of coaxial injectors with particular emphasis on those aspects relevant to the performance of rocket engines. Measurements for coaxial air blast atomizers were obtained using air to represent the gaseous stream and water to represent the liquid stream. A wide range of flow conditions were examined for sprays with and without swirl for gaseous streams. The parameters varied include Weber number, gas flow rate, liquid flow rate, swirl, and nozzle geometry. Measurements were made with a phase Doppler velocimeter. Major conclusions of the study focused upon droplet size as a function of Weber number, effect of gas flow rate on atomization and spray spread, effect of nozzle geometry on atomization and spread, effect of swirl on atomization, spread, jet recirculation and breakup, and secondary atomization.

    Atomic oxygen can be used to microscopically alter the surface morphology of polymeric materials in space or in ground laboratory facilities. For polymeric materials whose sole oxidation products are volatile species, directed atomic oxygen reactions produce surfaces of microscopic cones. However, isotropic atomic oxygen exposure results in polymer surfaces covered with lower aspect ratio sharp-edged craters. Isotropic atomic oxygen plasma exposure of polymers typically causes a significant decrease in water contact angle as well as altered coefficient of static friction. Such surface alterations may be of benefit for industrial and biomedical applications. The results of atomic oxygen plasma exposure of thirty-three (33) different polymers are presented, including typical morphology changes, effects on water contact angle, and coefficient of static friction.

    Many big earthquakes have occurred in the tectonic regions of the world, especially in Japan. Earthquakes often cause damage to crucial life services such as water, gas and electricity supply systems and even the sewage system in urban and rural areas. The most severe problem for people affected by earthquakes is access to water for their drinking/cooking and toilet flushing. Securing safe water for daily life in an earthquake emergency requires the establishment of countermeasures, especially in a mega city like Tokyo. This paper described some examples of groundwater use in earthquake emergencies, with reference to reports, books and newspapers published in Japan. The consensus is that groundwater, as a source of water, plays a major role in earthquake emergencies, especially where the accessibility of wells coincides with the emergency need. It is also important to introduce a registration system for citizen-owned and company wells that can form the basis of a cooperative during a disaster; such a registration system was implemented by many Japanese local governments after the Hanshin-Awaji Earthquake in 1995 and the Great East Japan Earthquake in 2011, and is one of the most effective countermeasures for groundwater use in an earthquake emergency. Emphasis is also placed the importance of establishing of a continuous monitoring system of groundwater conditions for both quantity and quality during non-emergency periods.

    Objectives Japan has actively reclassified substances ranging from prescription drugs to over-the-counter (OTC) drugs in recent years. The sale of most OTC drugs was deregulated several times and pharmacists’ supervision was deemed no longer mandatory. Japan established a new OTC evaluation system in 2015 to hear opinions from various stakeholders regarding medicine types to be reclassified. This study aimed to examine the new framework to identify candidate substances for reclassification. Moreover, we examined how to manage the safe, self-care use of OTC drugs in Japan. Methods The necessary regulatory information on OTC approvals as of January 2015 was collected using an Internet search and relevant databases. To highlight the characteristics of OTC drugs in Japan, the UK was selected as a comparison country because it too was actively promoting the reclassification of medicines from prescription to nonprescription status, and because of economic similarity. Results Japan and the UK have a risk-based classification for nonprescription medicines. Japan has made OTC drugs available with mandatory pharmacists’ supervision, face-to-face with pharmacists, or online instruction, which is similar to the “pharmacy medicine” practiced in the UK. Japan recently reformed the reclassification process to involve physicians and the public in the process; some interactions were back to “prescription-only medicine” in the UK. Conclusion It is expected that the opinion of marketers, medical professionals, and the public will improve the discussion that will greatly contribute to the safe use of drugs. Monitoring the new system will be noteworthy to ensure that OTC drug users are managing their self-care properly and visiting a doctor only when necessary. The supply methods are similar in Japan and the UK; however, the expected growth in the Japanese OTC market by the Cabinet and the industry is still uncertain. PMID:27555801

    Japan established a vaccine selection system, in which a committee evaluates veterinary influenza vaccines to determine if the vaccine should be updated. In 2013, it was concluded that the present equine influenza vaccine strains did not have to be updated, but clade 2 (Fc2) viruses of the Florida sublineage should be included. We collected three Fc2 viruses as candidates and conducted comparative tests. Results indicated that A/equine/Carlow/2011 (H3N8) is not suitable, because of its unstable antigenic characteristics. A comparison between A/equine/Richmond/1/2007 (H3N8) (Richmond/07) and A/equine/Yokohama/aq13/2010 (H3N8) (Yokohama/10) in eggs showed that they shared equal growth properties. Immunogenicity test in mice showed that Yokohama/10 induced higher HI antibody titers than Richmond/07. Therefore, we concluded that Yokohama/10 was the most suitable strain. PMID:28163276

    Polarography is an electroanalytical technique based on recording current-voltage curves using a dropping mercury as the working electrode. It can be used for investigations of both reductions and oxidations of inorganic and organic species. Before WWII the developments of this technique linked Prague (in the then Czechoslovakia) with Kyoto (in Japan, where reductions of organic compounds were first observed). After WWII wide use of this technique has developed, so that in the 1950s and 1960 it became the fifth most frequently used analytical technique. More recently the analytical applications were limited to those of heterogeneous solutions and analyses of some drugs. Its applications in physical organic chemistry involve studies of structure-reactivity relationships and applications to investigations of equilibria and kinetics of rapidly or slowly established processes.

    In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many fundamental questions in cosmology; such as the physics in the very early universe, the origin of the cosmic acceleration, and the nature of dark matter. The forthcoming radio telescope, the Square Kilometre Array (SKA), which will be the world's largest, will be able to open a new frontier in cosmology and will be one of the most powerful tools for cosmology in the coming decade. The cosmological surveys conducted by the SKA would have the potential not only to answer these fundamental questions but also deliver precision cosmology. In this article we briefly review the role of the SKA from the viewpoint of modern cosmology. The cosmological science led by the SKA-Japan Consortium (SKA-JP) Cosmology Science Working Group is also discussed.

  12. [Stem cell research and science and technology policy in Japan].

    2011-12-01

    In this paper I review the present condition of the regeneration medicine research using pluripotency and a somatic stem cell, and I describe the subject of the science and technology policy in Japan towards realization of regeneration medicine. The Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) supported research promotion by the prompt action in 2007 when establishment of the iPS cell was reported by Shinya Yamanaka. Although the hospitable support of the Japanese government to an iPS cell is continued still now, there are some problems in respect of the support to other stem cell researches, and industrialization of regeneration medicine. In order to win a place in highly competitive area of investigation, MEXT needs to change policy so that funds may be widely supplied also to stem cell researches other than iPS cell research.

    During the last decade, Japan has experienced the largest burden of chemical terrorism-related events in the world, including the: (1) 1994 Matsumoto sarin attack; (2) 1995 Tokyo subway sarin attack; (3) 1998 Wakayama arsenic incident; (4) 1998 Niigata sodium-azide incident; and (5) 1998 Nagano cyanide incident. Two other intentional cyanide releases in Tokyo subway and railway station restrooms were thwarted in 1995. These events spurred Japan to improve the following components of its chemical disaster-response system: (1) scene demarcation; (2) emergency medical care; (3) mass decontamination; (4) personal protective equipment; (5) chemical detection; (6) information-sharing and coordination; and (7) education and training. Further advances occurred as result of potential chemical terrorist threats to the 2000 Kyushu-Okinawa G8 Summit, which Japan hosted. Today, Japan has an integrated system of chemical disaster response that involves local fire and police services, local emergency medical services (EMS), local hospitals, Japanese Self-Defense Forces, and the Japanese Poison Information Center.

    The programmability of DNA makes it an attractive structure-directing ligand for the assembly of nanoparticle (NP) superlattices in a manner that mimics many aspects of atomic crystallization. However, the synthesis of multilayer single crystals of defined size remains a challenge. Though previous studies considered lattice mismatch as the major limiting factor for multilayer assembly, thin film growth depends on many interlinked variables. Here, a more comprehensive approach is taken to study fundamental elements, such as the growth temperature and the thermodynamics of interfacial energetics, to achieve epitaxial growth of NP thin films. Both surface morphology and internal thin film structure are examined to provide an understanding of particle attachment and reorganization during growth. Under equilibrium conditions, single crystalline, multilayer thin films can be synthesized over 500 × 500 μm(2) areas on lithographically patterned templates, whereas deposition under kinetic conditions leads to the rapid growth of glassy films. Importantly, these superlattices follow the same patterns of crystal growth demonstrated in atomic thin film deposition, allowing these processes to be understood in the context of well-studied atomic epitaxy and enabling a nanoscale model to study fundamental crystallization processes. Through understanding the role of epitaxy as a driving force for NP assembly, we are able to realize 3D architectures of arbitrary domain geometry and size.

    A new method of ultrasensitive trace-isotope analysis has been developed based upon the technique of laser manipulation of neutral atoms. It has been used to count individual {sup 85}Kr and {sup 81}Kr atoms present in a natural krypton sample with isotopic abundances in the range of 10{sup {minus}11} and 10{sup {minus}13}, respectively. The atom counts are free of contamination from other isotopes, elements,or molecules. The method is applicable to other trace-isotopes that can be efficiently captured with a magneto-optical trap, and has a broad range of potential applications.
