    Skiing and skiing techniques were introduced by the Austrians to Japanese soldiers in 1911. After that, skiing spread beyond the original purpose and recently produced the ski sciences. From a sports biomechanical aspect, the development of the study of ski jumping, alpine skiing, and the basic movement in skiing is introduced in this paper. One of the characteristic points of these studies in Japan was that the ski sciences were supported not only by biomechanists and physiologists, but also basically by physicists and engineers. The fundamental research and studies from divergent fields are supporting each other and being integrated into ski science.

    The nuclear energy policy in Japan is based on the Uranium-Plutonium fuel cycle with Light Water Reactors (LWR) and Fast Breeder Reactors (FBR). After the accident at Fukushima-Daiichi Nuclear Power Plant, the Japanese government recognizes the importance to ensure the flexibility for future nuclear power generation and then, it was specified in the latest Japanese strategic energy plan. Two research groups related to thorium fuelled nuclear systems and fuel cycle was set up in the Atomic Energy Society of Japan in 2013. One is a 'Research Committee on Nuclear Applications of Molten Salt'. The committee was established to discuss the current molten-salt technology including molten-salt cooled reactor, molten-salt fuelled reactor, accelerator driven system, fusion reactor blankets and dry reprocessing processes. Throughout two years discussion, the committee summarizes a current state of the art and issues of molten-salt application systems. Committee also discussed the handling technologies for molten-salt reactors especially in China and United Kingdom, issues of molten-salt application to fusion reactor, dry reprocessing of spent nuclear fuel, and non-nuclear application of molten-salt. Term of the committee will be extended for further research activities

    There has been growing attention on the effects of forest on physiological relaxation and immune recovery, particularly in forest medicine research, from a perspective of preventive medicine. Japan is a world leader in the accumulation of scientific data on forest medicine research. In this review, we summarize the research that has been conducted in this area since 1992. We conducted field experiment, involving 420 subjects at 35 different forests throughout Japan. After sitting in natural surroundings, these subjects showed decrease in the following physiological parameters compared with those in an urban control group: 12.4% decrease in the cortisol level, 7.0% decrease in sympathetic nervous activity, 1.4% decrease in systolic blood pressure, and 5.8% decrease in heart rate. This demonstrates that stressful states can be relieved by forest therapy. In addition, it should be noted that parasympathetic nervous activity was enhanced by 55.0%, indicating a relaxed state. The results of walking experiments provided similar results. Li et al. demonstrated that immune function was enhanced by forest therapy in middle-aged employees who volunteered to participate in these experiments. Natural killer cell activity, an indicator of immune function, was enhanced by 56% on the second day and returned to normal levels. A significant increase of 23% was maintained for 1 month even after returning to urban life, clearly illustrating the preventive benefits of forest therapy. In an indoor room experiment, we conducted tests with the following: 1) olfactory stimulation using wood smell, 2) tactile stimulation using wood, and 3) auditory stimulation using forest sounds. These indoor stimulations also decreased the blood pressure and pulse rate, and induced a physiological relaxation effect. We anticipate that forest medicine will play an increasingly important role in preventive medicine in the future.

    We investigated the degree of Japan's contribution to the nuclear medical research in the last decade. Articles published in 1991-2000 in highly reputed nuclear medical journals were accessed through the MEDLINE database. The number of articles having affiliation with a Japanese institution was counted along with publication year. In addition, shares of top-ranking countries were determined along with their trends over time. Of the total number of articles (7,788), Japan's share of articles in selected nuclear medical journals was 11.4% (889 articles) and ranked 2nd in the world after the USA (2,645 articles). The recent increase in the share was statistically significant for Japan (p=0.02, test for trend). Japan's share in nuclear medical research output is much higher than that in other biomedical fields. (author)

    Six hundreds and eighty earthquakes causing significant damage have been recorded since the 7. century in Japan. It is important to recognize faults that will or are expected to be active in future in order to help reduce earthquake damage, estimate earthquake damage insurance and siting of nuclear facilities. Such faults are called 'active faults' in Japan, the definition of which is a fault that has moved intermittently for at least several hundred thousand years and is expected to continue to do so in future. Scientific research of active faults has been ongoing since the 1930's. Many results indicated that major earthquakes and fault movements in shallow crustal regions in Japan occurred repeatedly at existing active fault zones during the past. After the 1995 Southern Hyogo Prefecture Earthquake, 98 active fault zones were selected for fundamental survey, with the purpose of efficiently conducting an active fault survey in 'Plans for Fundamental Seismic Survey and Observation' by the headquarters for earthquake research promotion, which was attached to the Prime Minister's office of Japan. Forty two administrative divisions for earthquake disaster prevention have investigated the distribution and history of fault activity of 80 active fault zones. Although earthquake prediction is difficult, the behaviour of major active faults in Japan is being recognised. Japan Nuclear Cycle Development Institute (JNC) submitted a report titled 'H12: Project to Establish the. Scientific and Technical Basis for HLW Disposal in Japan' to the Atomic Energy Commission (AEC) of Japan for official review W. The Guidelines, which were defined by AEC, require the H12 Project to confirm the basic technical feasibility of safe HLW disposal in Japan. In this report the important issues relating to fault activity were described that are to understand the characteristics of current fault movements and the spatial extent and magnitude of the effects caused by these movements, and to

    A virtual laboratory system for nuclear fusion research in Japan has been developed using SuperSINET, which is a super high-speed network operated by National Institute of Informatics. Sixteen sites including major Japanese universities, Japan Atomic Energy Agency and National Institute for Fusion Science (NIFS) are mutually connected to SuperSINET with the speed of 1 Gbps by the end of 2006 fiscal year. Collaboration categories in this virtual laboratory are as follows: the large helical device (LHD) remote participation; the remote use of supercomputer system; and the all Japan ST (Spherical Tokamak) research program. This virtual laboratory is a closed network system, and is connected to the Internet through the NIFS firewall in order to keep higher security. Collaborators in a remote station can control their diagnostic devices at LHD and analyze the LHD data as they were at the LHD control room. Researchers in a remote station can use the supercomputer of NIFS in the same environment as NIFS. In this paper, we will describe detail of technologies and the present status of the virtual laboratory. Furthermore, the items that should be developed in the near future are also described

    In Japan, the Condensed Matter Nuclear Science (CMNS) works have been centering around the Japan CF-Research Society (JCFRS) established in 1999. Recently, about 10 research groups were actively working in the CMNS field, and have been exchanging information mainly in the annual meetings of JCFRS in addition to the International ICCF conferences. For many years efforts have been exclusively devoted to clarification of the underlying physics of excess heat phenomenon and isotopic composition change. Recently, however, an entrepreneur group, Clean Planet Inc., has entered into the CMNS field in Japan, and joined Mizuno to form the above-mentioned group and made a presentation at the LANR/CF Colloquium, at MIT in March 2014. In their work they used glow discharge to form surface nanostructures on nickel mesh wires that are to be subjected to deuterium exposure. They claimed excess power on the order of kilowatts with a coefficient of performance of 1.9. Confirmation of their claim by third parties is highly expected

    1979-01-01

    The outline of the history of radiation research in Japan is written in connection with the names of researchers. Yoshio Nishina was a pioneer, who derived the Klein-Nishina formula for the scattering of hard X-ray by free electrons. In 1935, the first nuclear experiment laboratory was constructed in the Institute of Physical and Chemical Research. Two cyclotrons, 26 in and 60 in pole face diameter, and a high voltage Cockcroft-Walton type ion accelerator were installed. Irradiation of insects and plants with fast neutrons was attempted to examine the biological effect. In August, 1945, atomic bombs exploded in Hiroshima and Nagasaki. In 1950, radioisotopes were available. In early March, 1954, Bikini accident occurred. One fishing vessel was contaminated by radioactive fallout, and to investigate the effect of radioactivity, a committee consisted of investigators of physics, chemistry, medicine, biology, fisheries and geophysics was organized. The Japan Atomic Energy Research Institute was established in June, 1956. Several institutions for the peaceful use of atomic energy were established. The hybrid spark chamber to image the distribution of β-emitting isotopes on a plane surface was constructed in Nagoya University. As for the national project on food irradiation, one laboratory has played the role in irradiation techniques. Researches on radiation chemistry in universities, governmental and commercial organizations have been progressing steadily, and the machines for nanosecond to picosecond pulse radiolysis are working.

    The choice of sensor and actuator material as well as optimum design to combine the actuator element with the host structure become very essential to develop a smart materials and structures. In the present paper, first, the present state and issues of the main solid actuators are described from the viewpoint of material science and engineering. Next, the developments of smart materials and systems using shape memory materials in Japan are introduced. Shape memory TiNi fiber reinforced/Al or polymer matrix composites have been fabricated to confirm the enhancements of fracture toughness (K-value) by utilizing the compression stresses caused by shape memory shrinkage of embedded TiNi fibers. Sudden failure prevention system for structures are also proposed by combining non-destructive acoustic emission detecting system with suppression of crack-tip stress intensity by shape memory shrinkage effect. Lastly, the research project scheme and several targets on smart actuator development are introduced, which are imposed on the Tohoku University team in the Japanese National Project (1998∝2002 A.D.) on smart materials and structure system by NEDO/MITI.

    This project aims to do research on forecasts of energy demand structure and electricity generation cost in each power plant in Japan in the 21st century, considering constructing successful FBR scenario. During the process of doing research on forecasts of energy demand structure in Japan, documents published from organizations in inside and outside of Japan were collected. These documents include prospects of economic growth rate, forecasts of amount for energy supply and demand, the maximum amount of introducing new energy resources, CO2 regulation, and evaluation of energy best mixture. Organizations in Japan such as Economic Council and Japan Energy Economic Research Institute have provided long-term forecasts until the early 21st century. Meanwhile, organizations overseas have provided forecasts of economic structure, and demand and supply for energy in OECD and East Asia including Japan. In connection with forecasts of electricity generation cost in each power plant, views on the ultimate reserves and cost of resources are reviewed in this report. According to some views on oil reserves, making assumptions based on reserves/production ratio, the maximum length of the time that oil reserves will last is 150 years. In addition, this report provides summaries of cost and potential role of various resources, including solar energy and wind energy; and views on waste, safety, energy security-related externality cost, and the price of transferring CO2 emission right.

    Major nuclear research institutes in Japan are the Japan Atomic Energy Research Institute (JAERI), Nuclear Cycle Development Institute (JNC), National Research Institute of Radiological Science (NIRS), and the Institute of Physical and Chemical Research (RIKEN). In the 50s and 60s JAERI concentrated on the introduction of nuclear technology from overseas. Energy security issues led to the development of a strong nuclear power programme in the next two decades resulting in Japan having 50 light water cooled nuclear power plants in operation. Japan also worked on other reactor concepts. The current emphasis of JAERI is on advanced reactors and nuclear fusion. Its budget of 270 million US$ supports five research establishments. JAERI has strong collaboration with industry and university system on nuclear and other advanced research topics (neutron science, photon science). In many areas Japan has strong international links. JAERI has also been transferring know-how on radioisotope and radiation applications to the developing countries particularly through IAEA-RCA mechanisms. (author)

    The Japan Atomic Energy Commission has exerted efforts on the research of the safety of nuclear plants in Japan, and ''Nuclear plant safety research committees'' was established in August 1974, which is composed of the government and the people. The philosophy of safety research, research and development plan, the forwarding procedure of the plan, international cooperation, for example LOFT program, and the effective feed back of the experimental results concerning nuclear safety are reviewed in this paper at first. As for the safety of nuclear reactors the basic philosophy that radio active fission products are contained in fuel or reactors with multiple barriers, (defence in depth) and almost no fission product is released outside reactor plants even at the time of hypothetical accident, is kept, and the research and development history and the future plan are described in this paper with the related technical problems. The structural safety is also explained, for example, on the philosophy ''leak before break'', pipe rupture, pipe restraint and stress analysis. The release of radioactive gas and liquid is decreased as the philosophy ''ALAP''. And probability safety evaluation method, LOCA, reactivity, accident and aseismatic design in nuclear plants in Japan are described. (Nakai, Y.)

    Knowledge translation is an essential and emerging arena in healthcare research. It is the process of aiding the application of research knowledge into clinical practice or policymaking. Individuals at all levels of the health care system, including patients, healthcare professionals, and policymakers, are affected by the gaps that exist between research evidence and practice; the process of knowledge translation plays a role in bridging these gaps and incorporating high-quality clinical research into decision-making. Cardiovascular disease (CVD) management is a crucial area of healthcare where information gaps are known to exist. Although Japan has one of the lowest risks and mortality rates from CVDs, an increasing trend of cardiovascular incidence and changes in the risk factor conditions have been observed in recent years. This article provides an overview of knowledge translation and its importance in the cardiovascular health of the Japanese population, and describes the key steps of a typical knowledge translation strategy.

    SNET is a virtual laboratory system for nuclear fusion research in Japan, it has been developed since 2001 with SINET3, which is a national academic network backbone operated by National Institute of Computer sciences. Twenty one sites including major Japanese universities, JAEA and NIFS are mutually connected on SNET with the speed of 1 Gbps in 2008 fiscal year. The SNET is a closed network system based on L2 and L3 VPN and is connected to the web through the firewall at NIFS for security maintenance. Collaboration categories in SNET are as follows: the LHD remote participation; the remote use of supercomputer system; the all Japan ST (Spherical Tokamak) research program. For example, the collaborators of the first category in a remote station can control their diagnostic devices at LHD and analyze the LHD data as if they were at the LHD control room. The detail of the network policy is different from each other because each category has its own particular purpose. In October 2008, the Kyushu University and NIFS were connected by L2 VPN. The site was already connected by L3 VPN, but the data transfer rate was rather low. L2 VPN supports the bulk data transfer which is produced by QUEST, the spherical tokamak device at Kyushu University. The wide-area broadcast test began to distribute to remote stations the video which is presented at the front panel of the LHD control room. ITER activity started in 2007 and 'The ITER Remote Experimentation Centre' will be constructed at the Rokkasho village in Japan under ITER-BA agreement. SNET would be useful for distributing the data of ITER to Japanese universities and institutions. (authors)

    The reduced enrichment programs for the JRR-3M, JRR-4 and JMTR of Japan Atomic Energy Research Institute (JAERI) have been completed. The KUR of Kyoto University Research Reactor Institute (KURRI) has been partially completed and is still in progress under the Joint Study Program with Argonne National Laboratory (ANL). The JRR-3M commenced using LEU silicide fuel elements instead of LEU aluminide fuel elements in September, 1999. The Japanese Government approved a cancellation of the KUHFR Project in February 1991, and April 1994 the U.S. Government gave an approval to utilize HEU fuel in the KUR instead of the KUHFR. Therefore, the KUR will be operated with HEU fuel until March 2004, then the full core conversion with LEU silicide will be done. The first shipment of spent fuels since 1974 was done in August, 1999. (author)

    Recent advances in assisted reproductive technology (ART) have made it possible to circumvent many causes of male and female infertility. The right to have a child by ART has been respected for infertile couples. However, there are currently no legal regulations concerning ART in Japan, and this has resulted in social and ethical problems. Surrogacy involves particularly complex medical, ethical, social, and legal issues, and is frequently focused on as a major social concern. Uterine transplantation (UTx) is a potential alternative for young women with uterine factor infertility due to hysterectomy for treatment of a malignant uterine tumor or massive blood loss after delivery, or because of a congenital disease such as Mayer-Rokitansky-Küster syndrome. UTx has been examined in experimental animals as a basis for establishment of fecundity for young women with uterine factor infertility. In this review, we focus on surrogacy in Japan and UTx research, and discuss the current status and concerns in this field. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The Japanese nuclear power programme began with reactors imported from the United States. A natural uranium heavy water reactor using domestic materials was started in 1958. Subsequent progress was with light water reactors imported from the United States. Domestic reactor development was of a fast breeder reactor and an advanced thermal reactor. By March 1986 there were 32 commercial power plants in operation which produced approximately 23% of the electricity consumed in Japan. Ten more are under construction and six more are planned. Their location and comparative generating cost are tabulated. Energy demand and targets for nuclear power generation are discussed. The FBR advanced thermal reactor and high temperature reactor programmes are summarized. The Japanese nuclear fuel cycle - uranium prospecting, enrichment, reprocessing, the development of mixed oxide fuels, thermal recycling and radioactive waste management is also discussed. (U.K.)

    Bellows are employed as useful mechanical elements with their flexibility and imperviousness to liquid and gas in the system in which such chemically active substances as sodium are handled. Since the early time of development of Japanese LMFBR, bellows have been used e.g. for the shaft seal of small sodium valves. Bellows are employed in the fast experimental reactor JOYO which is now in operation and the fast prototype reactor MONJU whose design program is in final stage at the following parts: control rod drive mechanism; intermediate heat exchanger; small valve; mechanical penetration assembly of the containment boundary; outer piping of the double-walled primary system (for JOYO only). In addition, the application of bellows as thermal expansion joint to the main piping system is under consideration for future FBRs. This paper outlines the research and development work on bellows for FBR use in Japan. (author)

    The radiation source used for breeding in the early years was mainly X rays. After the 2nd World War, gamma ray sources such as 60 Co and 137 Cs came to take a leading role in radiation breeding. The institute of Radiation Breeding (IRB) of the Ministry of Agriculture, Forestry and Fisheries (MAFF) was established on April 16, 1960. A gamma field with 2000Ci of a 60 Co source, the main irradiation facility of the IRB, was installed to study the genetically responses of crop plants to chronic exposures of ionizing radiation and their practical application to plant breeding. This paper consisted of 'forty years of research on radiobiology and mutation breeding in Japan', 'topics of mutation breeding research in IRB', 'outline of released varieties by mutation breeding' and 'future of mutation breeding'. The number of varieties released by the direct use of induced mutation in Japan amounts to 163 as of November 2001. Crops in which mutant varieties have been released range widely: rice and other cereals, industrial crops, forage crops, vegetables, ornamentals, mushrooms and fruit trees, the number of which reaches 48. The number of mutant varieties is highest (31) in chrysanthemum, followed by 22 in rice and 13 in soybean. By the indirect use of mutants, a total of 15 varieties of wheat, barley, soybean, mat rush and tomato have been registered by MAFF. Recent advances in biotechnological techniques have made it possible to determine DNA sequences of mutant genes. Accumulating information of DNA sequences and other molecular aspects of many mutant genes will throw light on the mechanisms of mutation induction and develop a new field of mutation breeding.

    Recent research on human behavior has often collected empirical data from the online labor market, through a process known as crowdsourcing. As well as the United States and the major European countries, there are several crowdsourcing services in Japan. For research purpose, Amazon's Mechanical Turk (MTurk) is the widely used platform among those services. Previous validation studies have shown many commonalities between MTurk workers and participants from traditional samples based on not only personality but also performance on reasoning tasks. The present study aims to extend these findings to non-MTurk (i.e., Japanese) crowdsourcing samples in which workers have different ethnic backgrounds from those of MTurk. We conducted three surveys ( N = 426, 453, 167, respectively) designed to compare Japanese crowdsourcing workers and university students in terms of their demographics, personality traits, reasoning skills, and attention to instructions. The results generally align with previous studies and suggest that non-MTurk participants are also eligible for behavioral research. Furthermore, small screen devices are found to impair participants' attention to instructions. Several recommendations concerning this sample are presented.

    The reduced enrichment programs for the JRR-2, JRR-3, JRR-4 and JMTR of Japan Atomic Energy Research Institute (JAERI), and the KUR of Kyoto University Research Reactor Institute (KURRI) have been partially completed and are mostly still in progress under the Joint Study Programs with Argonne National Laboratory (ANL). The JMTR and JRR-2 have been already converted to use MEU aluminide fuels in 1986 and 1987, respectively. The operation of the upgraded JRR-3(JRR-3M) has started in March 1990 with the LEU aluminide fuels. Since May 1992, the two elements have been inserted in the KUR. The safety review application for the full core conversion to use LEU silicide in the JMTR was approved in February 1992 and the conversion has been done in January 1994. The Japanese Government approved a cancellation of the KUHFR Project in February 1991, and in April 1994 the U.S. Government gave an approval to utilize HEU in the KUR instead of the KUHFR. Therefore, the KUR will be operated with HEU fuel until 2001. Since March 1994, Kyoto University is continuing negotiation with UKAEA Dounreay on spent fuel reprocessing and blending down of recovered uranium, in addition to that with USDOE.

  7. Ultralow temperature helium compressor for Japan Atomic Energy Research Institute

    International Nuclear Information System (INIS)

    Asakura, Hiroshi

    1988-01-01

    Ishikawajima Harima Heavy Industries Co., Ltd. started the development of an ultralow temperature helium compressor for helium liquefaction in 1984 jointly with Japan Atomic Energy Research Institute, and has delivered the first practical machine to the Superconductive Magnet Laboratory of JAERI. For a large superconductive magnet to be used in the stable state for a fusion reactor, conventional superconductive materials (NbTi, NbTi 3 Sn, etc.) must be used, being cooled forcibly with supercritical helium. The supercritical helium which is compressed above the critical pressure of 228 kPa has a stable cooling effect since the thermal conductivity does not change due to the evaporation of liquid helium. In order to maintain the temperature of the supercritical helium below 4 K before it enters a magnet, a heat exchanger is used. The compressor that IHI has developed has the ability to reduce the vapor pressure of liquid helium from atmospheric pressure to 50.7 kPa, and can attain the temperature of 3.5 K. The specification of this single stage centrifugal compressor is: mass flow rate 25 - 64 g/s, speed 80,000 rpm, adiabatic efficiency 62 - 69 %. The structure and the performance are reported. (K.I.)

    Research, development and experience of radioactive wastes are presented in this paper. A total of about 330,000 drums of conditioned radioactive wastes arising from nuclear power plants such as low- and intermediate-level wastes (LLW) have been stored on-site. LLW from research activities and alpha-contaminated wastes (α-wastes) from the PNC Post-Irradiation Examination Facility for Experimental FBR Spent Fuel and Material have also been conditioned and stored in JAERI. Pilot-scale plants have been developed by JAERI and Tokyo Electric Co. for both plastic immobilization and wet oxidation of organic wastes with Fe(II) - H 2 O 2 . For the treatment of α-wastes, techniques such as incineration, acid digestion, electroslag melting and solidification into ceramics have been developed and will be demonstrated in the PNC Pu-contaminated Waste Treatment Facility in 1983. The safety evaluation of LLW for ocean dumping has been carried out with high pressure leaching test apparatus by JAERI and in sea site tests including the recovery of cold samples. A test facility for shallow-land disposal will be constructed by 1983. About 120 tonnes of LWR spent fuels have been reprocessed at the PNC Reprocessing Plant at Tokai since 1977 and, as a result, approximately 110 m 3 of HLW have been generated and stored in tanks. R and D efforts on HLW management have been performed on the basis of the policy established by the Japan Atomic Energy Commission. Vitrification technology has been developed since 1976 in a combination of cold laboratory tests, cold engineering tests and hot laboratory tests. The Vitrification Pilot Plant is planned for construction in the late 1980s. Surveys of potential geological formations for disposal and the development of engineered barriers and of repository systems are under way in PNC

    The international nature of science and engineering research demands that students have the skillsets necessary to collaborate internationally. However, limited options exist for science and engineering undergraduates who want to pursue research abroad. The NanoJapan International Research Experience for Undergraduates Program is an innovative response to this need. Developed to foster research and international engagement among young undergraduate students, it is funded by a National Science Foundation Partnerships for International Research and Education (PIRE) grant. Each summer, NanoJapan sends 12 U.S. students to Japan to conduct research internships with world leaders in terahertz (THz) spectroscopy, nanophotonics, and ultrafast optics. The students participate in cutting-edge research projects managed within the framework of the U.S-Japan NSF-PIRE collaboration. One of our focus topics is THz science and technology of nanosystems (or `TeraNano'), which investigates the physics and applications of THz dynamics of carriers and phonons in nanostructures and nanomaterials. In this article, we will introduce the program model, with specific emphasis on designing high-quality international student research experiences. We will specifically address the program curriculum that introduces students to THz research, Japanese language, and intercultural communications, in preparation for work in their labs. Ultimately, the program aims to increase the number of U.S. students who choose to pursue graduate study in this field, while cultivating a generation of globally aware engineers and scientists who are prepared for international research collaboration.

    The tsunami science and engineering began in Japan, the country the most frequently hit by local and distant tsunamis. The gate to the tsunami science was opened in 1896 by a giant local tsunami of the highest run-up height of 38 m that claimed 22,000 lives. The crucial key was a tide record to conclude that this tsunami was generated by a "tsunami earthquake". In 1933, the same area was hit again by another giant tsunami. A total system of tsunami disaster mitigation including 10 "hard" and "soft" countermeasures was proposed. Relocation of dwelling houses to high ground was the major countermeasures. The tsunami forecasting began in 1941. In 1960, the Chilean Tsunami damaged the whole Japanese Pacific coast. The height of this tsunami was 5-6 m at most. The countermeasures were the construction of structures including the tsunami breakwater which was the first one in the world. Since the late 1970s, tsunami numerical simulation was developed in Japan and refined to become the UNESCO standard scheme that was transformed to 22 different countries. In 1983, photos and videos of a tsunami in the Japan Sea revealed many faces of tsunami such as soliton fission and edge bores. The 1993 tsunami devastated a town protected by seawalls 4.5 m high. This experience introduced again the idea of comprehensive countermeasures, consisted of defense structure, tsunami-resistant town development and evacuation based on warning.

    1981-01-01

    Recent projects of the study on the biological effects of tritium in Japan, were reviewed. The investigations were about the behavior of tritium in food chain, i.e., intake to organ or tissue, retention, and distribution, and in genetic stage. As an example RBE studies on the induction of mutations in the silkworm and on transforming were described. Tritiated water was injected into wild type female pupae and radiation dose-rate was calculated from the radioactivity transmitted to the deposited eggs. γ-ray irradiation was carried out, in parallel, at approximately similar dose rates. RBE of THO for mutation fell between 1 and 2. The experiments with transforming principle of B. subtilis showed that the treatment of the bacterial spore with 3 H-glycelin or 3 H-water derived more inactive transformation with the decrease of the concentrations.

    1987-07-01

    Despite the recent drop in world oil prices, the Japanese government is continuing to stress energy conservation, because Japan relies on imports for 85% of its total energy requirements and virtually 100% of its petroleum. Japan stresses long-term developments and sees conservation as an integral part of its 50- to 100-year transition from fossil fuels to nuclear and renewable sources of energy. The Japanese government is targeting new materials, biotechnology, and electronics technologies as the foundation of Japan's economy in the 21st century. Most government research programs in Japan are governed by aggressive timetables and fixed technical goals and are usually guaranteed funding over a 5- to 10-year period. Of the major energy conservation research programs, the best known is the Moonlight Project, administered by the Ministry of International Trade and Industry (MITI), and oriented towards end-use technologies such as Stirling engines and advanced heat pumps. Parts of MITI's Basic Technologies for Future Industries Program involve research in new materials and bioreactors. The Science and Technology Agency's Exploratory Research in Advanced Technologies (ERATO) Program is also investigating these technologies while emphasizing basic research. Other ministries supporting research related to energy conservation are the Ministry of Education, Science, and Culture and the Ministry of Construction. For 1985, government spending for energy conservation research was at least $50 million. Private sector funding of energy conservation research was $500 million in 1984. A brief outline of major programs and key participants is included for several of the most relevant technologies. An overview of Japan's experience in international scientific collaboration is also included.

    2011-11-01

    In medical research, remarkable increase in collaboration with industry, public organizations such as universities, research institutions, and academic societies makes researchers to be more deeply involved with the activities of commercial entities. Activities of education and research, which are the responsibilities of academic institutions and societies, conflict with the interests of individuals associated with industrial-academic collaboration. Management of such conflict of interest (COI) is of much importance for academic institutions and societies to appropriately promote industrial-academic collaborative activities. Particularly, participation not only by healthy individuals, but also patients, is essential in the medical field as subjects of clinical research. For those involved in medical research, the deeper the level of COI with commercial entities, who are the financial or benefit provider, becomes serious, the more human rights of subjects could be violated, safety of life could be endangered, and research methods, data analysis and interpretation of results could be distorted. It is also possible that research may be unfairly evaluated or not published, even if the results are accurate, sometimes resulting in the ascertained effects of reporting bias included the overestimation of efficacy and the underestimation of safety risks of interventions. According to the COI management guideline of the Japanese Association of Medical Science (JAMS), significance of COI management is discussed.

    2016-07-01

    Research Ethics Committees (RECs) are designed to protect human subjects in research. It is essential to recognize whether the RECs are achieving this goal. Several studies have reported on RECs; however, detailed data regarding the quality of research protocols and the review process of RECs have not been reported in Japan. We examine research protocols reviewed by RECs and the review processes at three institutions using a novel checklist we developed. The data show that approximately half of all examined protocols lacked a clearly written "Background" section that defines the study rationale and design. These results reiterate suggestions made in previous research regarding educational programs and support departments that could enhance responsible conduct in clinical research to protect human subjects in Japan. © The Author(s) 2016.

  12. State of research and perspective on adaptive response to low doses of ionizing radiation in Japan

    1997-01-01

    In a review article entitled ''Physical Benefits from Low Levels of Ionizing Radiation,'' published in Health Physics in December of 1982, Professor T.D. Luckey of the University of Missouri, asserted the ''radiation hormesis'' with 200 references. This resulted in the first International Symposium on Radiation Hormesis in Oakland, California (August 1985). CRIEPI consulted many specialists about Luckey's paper and studied many other papers such as Lorenz, 1954; Luckey, 1980, Liu et al., 1985. Radiation hormesis research in Japan has been based on the rationale that if Luckey's claim were to be true, radiation management in Japan has been extremely erroneous. CRIEPI organized a Hormesis Research Steering Committee composed of leading specialists in the field concerned, and began research in cooperation with a number of universities, as well as the National Cancer Research Institute, and the National Institute of Radiological Sciences. After obtaining interesting results in various experiments on the health effects of exposure to low doses of radiation, we have proceeded on an expanded program, which involves fourteen universities and two research institutes throughout Japan. The interesting results we obtained can be categorized in five groups. 1. Enhancement of immune systems such as lymphocytes and suppression of cancer, 2. Radio-adaptive response relating to the activation of DNA repair and adoptosis, 3. Rejuvenation of cells such as increase of SOD and cell membrane permeability, 4. Radiation effect on neuro-transmitting system through increase of key enzymes, 5. Others, including the therapy of adult-disease such as diabetes and hypertension. We are now carrying out experimental activities on the effects of low-dose radiation on mammals. After several years of research activities, we are recognizing Luckey's claim. Some basic surveys including Hiroshima Nagasaki and animal experiments in Japan have brought us valuable informations on the health effects of low

  3. Present status of tritium research activities at universities in Japan

    International Nuclear Information System (INIS)

    Kawamura, K.

    1983-01-01

    The behaviours of tritium towards various materials are very similar to those of hydrogen, since tritium is one of the hydrogen isotope. In addition to those properties, tritium shows the radiochemical and radiological reactivities due to an emitted #betta#-ray. The permeability of tritium through various materials is the example of the former. The formation of tritiated methane in tritium stored in stainless steel vessels and the increase of helium content in tritium-bearing metallic materials are the examples of the latter. For these reasons, advanced and somewhat more complicated techniques are required for handling tritium. After the Ministry of Education, Science and Culture (MOE) made an appropriation on Grant-in-Aid for Fusion Research in 1975 year's budget, development of tritium handling technology for fusion reactors have been actively pursued. The specific experiments to be embodied in present research activities are: 1. Measurements of tritium permeation rate through various materials. 2. Fundamental studies on tritium containment materials. 3. Fundamental studies of tritium waste treatment and storage. In this paper, the works achieved under the above research activities are described and some results obtained from experiments are reported. (author)

    2011-03-01

    This article specifically examines several aspects of the human-captive chimpanzee bond and the effort to create the first chimpanzee sanctuary in Japan. We discuss our ethical responsibility for captive chimpanzees that have been used in biomedical research. On April 1, 2007, the Chimpanzee Sanctuary Uto (CSU) was established as the first sanctuary for retired laboratory chimpanzees in Japan. This initiative was the result of the continuous efforts by members of Support for African/Asian Great Apes (SAGA), and the Great Ape Information Network to provide a solution to the large chimpanzee colony held in biomedical facilities. However, the cessation of invasive biomedical studies using chimpanzees has created a new set of challenges because Japan lacks registration and laws banning invasive ape experiments and lacks a national policy for the life-long care of retired laboratory chimpanzees. Therefore, CSU has initiated a relocation program in which 79 retired laboratory chimpanzees will be sent to domestic zoos and receive life-long care. By the end of 2009, the number of chimpanzees living at CSU had decreased from 79 to 59 individuals. A nationwide network of care facilities and CSU to provide life-long care of retired laboratory chimpanzees is growing across Japan. This will result in humane treatment of these research animals. 2010 Wiley-Liss, Inc.

This study aimed to evaluate doctoral nursing programs by faculty members and to analyze the relationship of the evaluation with educational and research activities of faculty members in Japan. Target settings were all 46 doctoral nursing programs. Eighty-five faculty members from 28 programs answered the questionnaire, which included 17 items for program evaluation, 12 items for faculty evaluation, 9 items for resource evaluation, 3 items for overall evaluations, and educational and research activities. A majority gave low evaluations for sources of funding, the number of faculty members and support staff, and administrative systems. Faculty members who financially supported a greater number of students gave a higher evaluation for extramural funding support, publication, provision of diverse learning experiences, time of supervision, and research infrastructure. The more time a faculty member spent on advising doctoral students, the higher were their evaluations on the supportive learning environment, administrative systems, time of supervision, and timely feedback on students' research. The findings of this study indicate a need for improvement in research infrastructure, funding sources, and human resources to achieve quality nursing doctoral education in Japan.

    1990-01-01

    On the smoking occurred on May 30, 1989 in the uranium enrichment research building, the investigation has been carried out about the presumed cause and the countermeasures for preventing the recurrence, and the following report was presented. In the uranium scrap after the oxidation treatment of vapor-deposited metallic uranium was carried out, a small quantity of unoxidized part having reactivity remained. This unoxidized part existing locally reacts with air in a container, and there is the possibility of generating heat after about one day. In this accident, unoxidized part existed near the wall of a polyethylene vessel, and the oxidation and heat generation reaction advanced. The vessel broke, air supply increased, and heat generation spread. After the temperature reached 300degC, the oxidation of UO 2 to U 3 O 8 took part, thus the polyethylene vessel and others generated smoke. As the countermeasures, for the preservation of uranium scrap, metallic vessels are used, and the atmosphere of inert gas or vacuum is maintained. The uranium scrap containing unoxidized part is rapidly oxidized. The uranium enrichment research building was decontamination. (K.I.)

    The Japanese steel industry consumes about 18% of total energy consumption in Japan, and 56 million tons of coking coal were imported in 1977 at the cost of approximately $3.3 billion. Securing of required quantity of coking coal, price negotiation, the transport and storage of coal, and environmental pollution are the problems concerning the steel industry. In order to solve these problems, the introduction of atomic energy to steel-making is considered. The use of high temperature gas-cooled reactors is capable of supplying large quantities of heat and electric power which are required for steel-making. The Committee on Utilization of Nuclear Energy, the Iron and Steel Institute of Japan, was established in 1968, and the research and development of nuclear steel-making were started as a national project in 1973. The outline of nuclear steel-making system is explained. The Japan Atomic Energy Research Institute is promoting the research and development on a multi-purpose HTGR with 1000 deg C outlet helium temperature. The research and development in progress now are as follows: high temperature heat exchangers, heat resistant superalloys, high temperature heat insulating materials, reducing gas-producing unit, reduced iron-producing system, and the total system for nuclear steel-making.

    Structural materials for next-generation nuclear power systems should have a good radiation resistance, where the expected accumulation dose will largely exceed 10 dpa. Among several candidate materials, materials of five categories, 1. Austenitic steels, including high nickel alloys, 2. Low activation ferritic martensitic steels, 3. ODS steels (austenitic and ferritic), 4. Vanadium based alloys, 5. Silicon carbide composites (SiC/SiCf). All have been most extensively studied in Japan, in collaboration among industries, national institutes such as Japan Atomic Energy Agency (JAEA), National Institute for Fusion Science (NIFS) and National Institute for Materials Science (NIMS), and universities. The high nickel base alloys were studied for their low swelling behaviors mainly by the NIMS and the austenitic steels are studied for their reliable engineering data base and their reliable performance in irradiation environments mainly by the JAEA, mainly for their application in the near-term projects such as the ITER and the Sodium Cooled Fast Reactors. The most extensive studies are now concentrated on the Low Activation Ferritic Marsensitic steels and ODS steels, for their application in a demonstration fusion reactor and prototype sodium cooled fast reactors. Fundamental studies on radiation effects are carried out, mainly utilizing Japan Materials Testing Rector (JMTR) with its flexible irradiation ability, up to a few dpa. For higher dpa irradiation, a fast test reactor, JOYO is utilized up to several 10s dpa. Some international collaborations such as Japan/USA and Japan/France are effective to utilize reactors abroad, such as High Flux Isotope Reactor (HFIR) of Oak Ridge National Laboratory, and sodium cooled high flux fast reactors in France. Silicon carbide based composites are extensively studied by university groups led by Kyoto University and the JAEA. For their performance in heavy irradiation environments, the Japan/USA collaboration plays an important role

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

    Highlights: • Chernobyl accident had limited influence on basic research in nuclear energy. • Budget allocation to R and D and number of published papers have recently decreased. • Citation network analysis revealed reactor safety and fusion as current research trend. • Nuclear energy research policy will change after Fukushima disaster. - Abstract: The decision-making process that precedes the introduction of a new energy system should strive for a balance among human security, environmental safeguards, energy security, proliferation risk, economic risks, etc. For nuclear energy, the Fukushima Daiichi nuclear disaster (Fukushima disaster) has brought forth a strong need for transvaluation of the present technology. Here, we analyzed bibliographic records of publications in nuclear science and technology to illustrate an overview and trends in nuclear energy technology and related fields by using citation network analysis. We also analyzed funding data and keywords assigned for each project by co-occurrence network analysis. This research integrates citation network analysis and bibliometric keyword analysis to compare the global trends in nuclear energy research and characteristics of research conducted at universities and institutes in Japan. We show that the Chernobyl accident had only a limited influence on basic research. The results of papers are dispersed in diverse areas of nuclear energy technology research, and the results of KAKEN projects in Japan are highly influenced by national energy policy with a focus on nuclear fuel cycle for energy security, although KAKEN allows much freedom in the selection of research projects to academic community

    Purpose of this study is to explore the status of R and D in Japan and the ability of US researchers to keep abreast of Japanese technical advances. US researchers familiar with R and D activities in Japan were interviewed in ten fields that are relevant to the more efficient use of energy: amorphous metals, biotechnology, ceramics, combustion, electrochemical energy storage, heat engines, heat transfer, high-temperature sensors, thermal and chemical energy storage, and tribology. The researchers were questioned about their perceptions of the strengths of R and D in Japan, comparative aspects of US work, and the quality of available information sources describing R and D in Japan. Of the ten related fields, the researchers expressed a strong perception that significant R and D is under way in amorphous metals, biotechnology, and ceramics, and that the US competitive position in these technologies will be significantly challenged. Researchers also identified alternative emphases in Japanese R and D programs in these areas that provide Japan with stronger technical capabilities. For example, in biotechnology, researchers noted the significant Japanese emphasis on industrial-scale bioprocess engineering, which contrasts with a more meager effort in the US. In tribology, researchers also noted the strength of the chemical tribology research in Japan and commented on the effective mix of chemical and mechanical tribology research. This approach contrasts with the emphasis on mechanical tribology in the US.

    Since starting the research and development program for peaceful use of nuclear energy in 1950's, various research and demonstration facilities have been constructed in research organizations, universities and commercial sectors in Japan. Some of the nuclear facilities constructed in the early stage of research and development have been retired to be decommissioned because of completion of the initial objectives in the Japan Atomic Energy Research Institute (JAERI). On the other hand, since the first commercial operation of nuclear power plant (1968), the number of nuclear power plants has increased up to 52 plants operating as of August 2003 in Japan. The shear of nuclear energy accounts approximately for 35% of electricity generation in total at present time. However, several nuclear power plants have been operated for more than 25 years and two nuclear power plants are expected to be finally shutdown by 2010 to be eventually decommissioned. The Tokai Power Station, the oldest Japanese nuclear power plant operated by the Japan Atomic Power Company, was permanently shutdown from March 1998 and it is in decommissioning stage at this time. The Fugen, which is advanced thermal reactor operated by the Japan Nuclear Cycle Development Institute (JNC), was finally shutdown on March, 2003 after 25 years operation to be decommissioned. In addition, relating to planned unification between JAERI and JNC in 2005, the studies have been in progress on decommissioning and radioactive waste treatment and disposal; the cost was estimated to be 10 to 30 billion Japanese yens per year during 80 years for decommissioning of nearly 200 nuclear facilities. Decommissioning of nuclear facilities is thus getting to be one of important issues in Japan. Decommissioning of nuclear facilities might be possible using conventional and/or partially improved technology. However, reviewing project feedback experience on decommissioning and decontamination might contribute to solve various issues

    Dealing with the new road map published in 2009 by the NEDO (New Energy and Industrial Technology development Organization) for the research activity in photovoltaic electricity production in Japan from now until 2030, this brief embassy report first outlines the need for such a new road map as Japan's international competitiveness is more and more challenged: it only possesses 10% of the installed power in the world (50% in 2003) and ranks now in sixth position in terms of annual installed power. Beside this trend, environmental challenges and CO 2 emission reduction objectives, as well as oil price increase, have driven the NEDO to review its road map sooner as foreseen. The author describes the contents of the three main axis which have been defined for the photovoltaic development: photovoltaic profitability improvement (grid parity objective by 2030, production cost reduction), broadening of photovoltaic uses and applications, development and competitiveness of Japanese industries

    The Safety Monitor Joint Working Group (JWG) is one of the magnetic fusion research collaborations between the US Department of Energy and the government of Japan. Visits by occupational safety personnel are made to participating institutions on a biennial basis. In the 2013 JWG visit of US representatives to Japan, the JWG members noted a number of good safety practices in the safety walkthroughs. These good practices and safety culture topics are discussed in this paper. The JWG hopes that these practices for worker safety can be adopted at other facilities. It is a well-known, but unquantified, safety principle that well run, safe facilities are more productive and efficient than other facilities (Rule, 2009). Worker safety, worker productivity, and high quality in facility operation all complement each other (Mottel, 1995).

    1982-01-01

    The Central Research Institute of Electric Power Industry has started the feasibility study to evaluate the possiblity of existence of large pool type FBR plants in Japan as the three-year project from fiscal 1981. The development of FBRs is indispensable for the effective use of nuclear fuel and the establishment of energy security. The knowledge on the characteristics of FBR core, sodium technology and others has advanced rapidly in Japan. At the stage of the practical reactors with large capacity, the pool type is naturally considered as the object of selection, but the aseismatic capability and safety of the large containment vessels for the pool type and the qualitative and quantitative acceptability of the research and development for the pool type are the problems. The difference between the loop type and the pool type is only the structural change arising from the difference in the arrangement of equipment. The pool type reactors have been operated already in the UK and France. The objective of the research and main subjects, the total plan and research organization, the fundamental condition of investigation, the research procedure for respective subjects, and the outline of model test are discribed. The change of design and safety standards in the future must be predicted and taken in consideration in the research. (Kako, I.)

    The Engineering and Design Activity (EDA) of the International Thermonuclear Experimental Reactor (ITER) started operation with the cooperation of Japan, EU, Russia and the US in July 1992 with a plan to do work on the design of the ITER and necessary R and D. Six years passed and the final report was completed in February 1998, reporting that the initial targets were almost achieved except for design work depending on construction site. It was also decided to prolong the EDA for more three years, though the US did not participate. The new EDA items include: Design to meet site requirements and cost estimation; preparation for application for construction approval; and preparation of technical documents for equipment procurement in the future. Among them, the main EDA item is to design a low-cost ITER to be ready for construction when the three-year joint research is ended. For this, work was done to prepare technical guidelines. The EDA is now making the conceptual design of a new ITER 50% less expensive than the current ITER described in the final design report. Japan has proposed site requirements that are needed for design alteration when the ITER is constructed in Japan. The site requirements are concerned with earthquake resistance, ground, power supply and cooling conditions. (N.H.)

    In Japan, 4 nuclear power stations are under decommissioning and some nuclear fuel cycle facilities are expected to be decommissioned in the future. On the other hand, the safety regulation of decommissioning of nuclear facilities was changed by amending act in 2005. An approval system after review process of decommissioning plan was adopted and applied to the power stations above. In this situation, based on the experiences of the new regulatory system, the system should be well established and moreover, it should be improved and enhanced in the future. Nuclear Industry and Safety Agency (NISA) is in charge of regulation of commercial nuclear facilities in Japan and decommissioning of them is included. Japan Nuclear Energy Safety Organization (JNES) is in charge of technical supports for NISA as a TSO (Technical Support Organization) also in this field. As for decommissioning, based on regulatory needs, JNES has been continuing research activities from October 2003, when JNES has been established. Considering the 'Prioritized Nuclear Safety Research Plan (August 2009)' of the Nuclear Safety Commission of Japan and the situation of operators facilities, 'Regulatory Support Research Plan between FY 2010-2014' was established in November 2009, which shows the present regulatory needs and a research program. This program consists of researches for 1. review process of decommissioning plan of power reactors, 2. review process of decommissioning plan of nuclear fuel cycle facilities, 3. termination of license at the end of decommissioning and 4. management of decommissioning waste. For the item 1, JNES studied safety assessment methods of dismantling, e.g. obtaining data and analysis of behavior of dust diffusion and risk assessment during decommissioning, which are useful findings for the review process. For the item 2, safety requirements for the decommissioning of nuclear fuel cycle facilities was compiled, which will be used in the future review. For the item 3

    In 2006, the Cancer Control Act was approved and a Basic Plan, to Promote the Cancer Control Program at the national level, was developed in 2007. Cancer research is recognized as a fundamental component to provide evidence in cancer control program. Cancer epidemiology plays central role in connecting research and policy, since it directly deals with data from humans. Research for cancer epidemiology in Japan made substantial progress, in the field of descriptive studies, cohort studies, intervention studies and activities for summarizing evidences. In future, promoting high-quality large-scale intervention studies, individual-level linkage studies, simulation models and studies for elderly population will be of great importance, but at the same time research should be promoted in well-balanced fashion not placing too much emphasis on one particular research field. © The Author 2015.

    The temporal losses of confinement during edge localized modes in the Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-60U) show multifractal scaling and the spectra are generally smooth, but in some cases there are signs of discontinuous derivatives. Dynamics of the Sugama-Horton model, interpreted as edge localized modes, also display multifractal scaling. The spectra display singularities in the derivative, which can be interpreted as a phase transition. It is argued that the multifractal spectra of edge localized modes can be used to discriminate between different experimental discharges and validate edge localized mode models

    Full Text Available Health technology assessment (HTA has been continuously used for value-based healthcare decisions over the last decade. Healthcare databases represent an important source of information for HTA, which has seen a surge in use in Western countries. Although HTA agencies have been established in Asia-Pacific region, application and understanding of healthcare databases for HTA is rather limited. Thus, we reviewed existing databases to assess their potential for HTA in Thailand where HTA has been used officially and Japan where HTA is going to be officially introduced.Existing healthcare databases in Thailand and Japan were compiled and reviewed. Databases' characteristics e.g. name of database, host, scope/objective, time/sample size, design, data collection method, population/sample, and variables were described. Databases were assessed for its potential HTA use in terms of safety/efficacy/effectiveness, social/ethical, organization/professional, economic, and epidemiological domains. Request route for each database was also provided.Forty databases- 20 from Thailand and 20 from Japan-were included. These comprised of national censuses, surveys, registries, administrative data, and claimed databases. All databases were potentially used for epidemiological studies. In addition, data on mortality, morbidity, disability, adverse events, quality of life, service/technology utilization, length of stay, and economics were also found in some databases. However, access to patient-level data was limited since information about the databases was not available on public sources.Our findings have shown that existing databases provided valuable information for HTA research with limitation on accessibility. Mutual dialogue on healthcare database development and usage for HTA among Asia-Pacific region is needed.

    Thermally stimulated current (TSC) measurement is widely used in a variety of research fields, i.e., physics, electronics, electrical engineering, chemistry, ceramics, and biology. TSC is short-circuit current that flows owing to the displacement of charges in samples during heating. TSC measurement is very simple, but TSC curves give very important information on charge behaviors. In the 1970s, TSC measurement contributed greatly to the development of electrical insulation engineering, semiconductor device technology, and so forth. Accordingly, the TSC experimental technique and its analytical method advanced. Over the past decades, many new molecules and advanced functional materials have been discovered and developed. Along with this, TSC measurement has attracted much attention in industries and academic laboratories as a way of characterizing newly discovered materials and devices. In this review, we report the latest research trend in the TSC method for the development of materials and devices in Japan.

    The public sector is an important source of agricultural research as the agricultural sector in many countries consists of a number of individual farmers who have difficulty in bearing the cost of research and development. Public institutes for testing and research called Kosetsushi help agriculture and manufacturing improve labor productivity through technology transfer activities, whereby constituting an important component of regional innovation systems in Japan. This study establishes panel data of agricultural Kosetsushi and examines whether their research activities are responsive to local needs and which type of research effort is conducive to the promotion of agricultural product innovations. Estimation results reveal variations across plants in the impacts of agricultural clusters on research on the plant conducted by Kosetsushi located in the cluster. A positive impact is observed only for vegetable while negative or statistically insignificant relationships are found for rice, fruit, and flower. The impact of research on plant breeding on agricultural product innovations also varies across plants. Policy implications of the major findings are discussed.

    Bibliometric analysis was carried out for champion data comparisons among prestigious nuclear research institutes (PNRI) existed in Japan, the U. S., France, and Germany. The analysis was relied on database INIS (IAEA), ECD (DOE), WOS (Thomson), and SCOPUS (Elsevier). INIS is advanced, key ex-post evaluating tool for determining general research paper-based champion. Over the 30-year time span of research paper publication, the world champion among 11 PNRI is JAERI confirmed by INIS but ORNL confirmed by ECD, WOS, and SCOPUS, the latter two collected journal submitted research paper. Five years ago JAERI is the 3rd ranked institutes following ORNL and ANL. INIS database results revealed that CEA/Grenoble is the French domestic champion regarding research paper publication. Five years ago it was CEA/Saclay. Results from analytical tools used in bibliometric studies should be viewed with careful consideration to learn of any influencing factors because different characteristics exhibited by individual databases can sometimes generate conflicting bibliometric results. This was true among INIS, ECD, WOS, and SCOPUS when looking at trends especially between 5-year periods. (author)

    Integrated library system has been developed using a stand-alone mini-computer in the Japan Atomic Energy Research Institute library. This system consists of three subsystems for serials control, books acquisition and circulation control. Serials control subsystem deals with subscription, acquisition, claiming and inquiry of journals. This has been operating since the beginning of 1985. Book acquisition sub-system, which has been started since April 1986, deals with accounting and cataloguing of books. Circulation control sub-system deals with circulation, statistics compilation, book inventory and retrieval, which has been operating since April 1987. This system contributes greatly not only to the reduction of the circulation work load but also to the promotion of the library services. However, the convenience in circulation processing should be improved for materials without catalogue information stored in the computer. The pertinence for maximum number of books retrieved has to be also reconsidered. (author)

    On March 11(th) 2011, the Tohoku region of Japan was struck by catastrophic disasters. Thousands of people were killed due to a magnitude 9.0 earthquake and its subsequent tsunami. Furthermore, a serious nuclear crisis occurred in Fukushima Prefecture as a result of the disasters, and an emergency evacuation was ordered to people living near the nuclear power plants. There was a lot of anxiety regarding lost families as well as the influences of radioactivity on the health of people and their children. Based on these urgent and uncertain situations, a number of research projects were developed at many institutes both inside and outside Fukushima. We herein report the investigative research projects related to the Tohoku Earthquake (The Great East Japan Earthquake) conducted after the disasters. The research projects were reviewed by the Institutional Review Board in Fukushima Medical University during the two years following the disasters. The research projects conducted in universities other than Fukushima Medical University were also examined using questionnaire analysis. Among the research projects conducted in Fukushima Medical University (n=424), 7% (n=32) were disaster-related investigative research. The mean duration planned to pursue the projects was 25.5 months. Among these projects, those focusing on the health of Fukushima citizens were most common (n=9), followed by the influence of chronic exposure of radiation on chronic inflammatory disorders (n=6), and the mental health of Fukushima citizens (n=5). They were carefully reviewed for the purpose, suitability, and necessity from ethical as well as scientific viewpoints. The majority of the research projects focused on the effects of the Tohoku Earthquake and/or chronic exposure to low-dose radioactivity on the health of children and pregnant women, as well as on various disorders, such as mental health and chronic inflammatory diseases. On the other hand, among 58 projects we collected from 22

    This paper is an overview of the PNC's Mizunami Underground Research Laboratory project in Mizunami City, central Japan. The Mizunami Underground Research Laboratory now will succeed the Kamaishi Mine as the main facility for the geoscientific study of the crystalline environment. The site will never be considered as a site for a repository. The surface-based investigations, planned to continue for some 5 years commenced in the autumn 1997. The construction of the facility to the depth of 1000 m is currently planned to: Develop comprehensive investigation techniques for geological environment; Acquire data on the deep geological environment and to; Develop a range of engineering techniques for deep underground application. Besides PNC research, the facility will also be used to promote deeper understanding of earthquakes, to perform experiments under micro-gravity conditions etc. The geology of the site is shortly as follows: The sedimentary overburden some 20 - 100 m in thickness is of age 2 - 20 million years. The basement granite is approx. 70 million years. A reverse fault is crosscutting the site. The identified fault offers interesting possibilities for important research. Part of the work during the surface-based investigations, is to drill and test deep boreholes to a planned depth up to 2000 m. Based on the investigations, predictions will be made what geological environment will be encountered during the Construction Phase. Also the effect of construction will be predicted. Methodology for evaluation of predictions will be established

    Sleeboom-Faulkner, Margaret

    2010-01-01

    This article explores the reasons for the lack of a broad discussion on bioethical regulation of human embryonic stem cell research (hESR) in Japan and asks why scientists experience difficulties accessing resources for hESR despite the acclaimed indifference of dominant Japanese culture to embryo research. The article shows how various social actors express their views on the embryo and oocyte donation in terms of dominant Japanese culture, foiled against what is regarded as Western culture. Second, it shows how the lack of concern with hESR should be understood in the context of public health policies and communications and bioethics decision making in Japan. Finally, it interprets the meaning of the embryo in the context of Japan as an aging modern welfare society, explaining how policymakers have come to emphasize the urgency of infertility problems over issues around abortion and embryonic life.

The ancillary role of e-mail based distribution lists as an essential instruction tool within an interactive, instructor-supervised online course is discussed. This article then discusses the inclusion of active learning elements within an online course as well as the pros and cons regarding open-book versus closed book, proctored testing. Lastly, copyright issues the online instructor should know about are discussed. The student tracking data show that as the course progresses, students will reduce the number for page viewings. We speculate that this reduction is due to a combination of conflicting priorities plus increasing efficiency of the students at extracting the critical information. The article also concludes that software and hardware costs to deliver an online course are relatively minor but the faculty's time requirement is initially substantially higher than teaching in a conventional face-to-face course.

    This paper reviews the present state of researches on tectonic uplift and denudation, and shows perspective goals and direction of future researches from the viewpoint of geological disposal of HLW in Japan. Detailed history of tectonics and denudation in geologic time scale, including the rates, temporal and spatial distributions and processes, reconstructed from geologic and geomorphologic evidences will enable us to make the geological predictions. Improvements of the analytic methods for the geological histories, e.g. identification of the tectonic and denudational imprints and age determinations, are indispensable for the accurate prediction. Developments of the tools and methodologies for assessments of the degree and extension of influences by the tectonic uplift, subsidence and denudation on the geological environments such as ground water flows are also fundamental problem in the study field of the geological disposal of HLW. Collaboration of scientific researches using the geological and geomorphological methods and applied technology, such as numerical simulations of ground water flows, is important in improving the safety and accuracy of the geological disposal of HLW.

    Sake is an alcoholic beverage of Japan, with a tradition lasting more than 1,300 years; it is produced from rice and water by fermenting with the koji mold Aspergillus oryzae and sake yeast Saccharomyces cerevisiae. Breeding research on sake yeasts was originally developed in Japan by incorporating microbiological and genetic research methodologies adopted in other scientific areas. Since the advent of a genetic paradigm, isolation of yeast mutants has been a dominant approach for the breeding of favorable sake yeasts. These sake yeasts include (a) those that do not form foams (produced by isolating a mutant that does not stick to foams, thus decreasing the cost of sake production); (b) those that do not produce urea, which leads to the formation of ethyl carbamate, a possible carcinogen (isolated by positive selection in a canavanine-, arginine-, and ornithine-containing medium); (c) those that produce an increased amount of ethyl caproate, an apple-like flavor (produced by isolating a mutant resistant to cerulenin, an inhibitor of fatty-acid synthesis); and (d) those that produce a decreased amount of pyruvate (produced by isolating a mutant resistant to an inhibitor of mitochondrial transport, thus decreasing the amount of diacetyl). Given that sake yeasts perform sexual reproduction, sporulation and mating are potent approaches for their breeding. Recently, the genome sequences of sake yeasts have been determined and made publicly accessible. By utilizing this information, the quantitative trait loci (QTLs) for the brewing characteristics of sake yeasts have been identified, which paves a way to DNA marker-assisted selection of the mated strains. Genetic engineering technologies for experimental yeast strains have recently been established by academic groups, and these technologies have also been applied to the breeding of sake yeasts. Sake yeasts whose genomes have been modified with these technologies correspond to genetically modified organisms (GMOs

    In fiscal 1987, the Atomic Energy Commission of Japan revised the 'Long term program for development and utilization of nuclear energy', which is done every five years. It determined the future direction of the research and development in JAERI. Three basic objectives are indicated in it, that is, to qualitatively upgrade nuclear technology, to tackle the frontiers of the technology, and to promote international collaboration. The new 'Long term task plan' of JAERI based on the 'Long term program' was established in August, 1987. The integral experiment on loss of coolant accident, the test on reactivity-initiated accident, the irradiation and post-irradiation examination of fuel, the development of safety analysis codes, the design and safety analysis of the Nuclear Fuel Cycle Safety Engineering Research Facility, the treatment and disposal of radioactive wastes, the preparatory work for constructing the High Temperature Engineering Test Reactor, the full scale plasma heating experiment with JT-60, the study on high efficiency confinement mode and current drive, the construction of the new home port for the nuclear ship 'Mutsu', the design of an advanced marine reactor, the reactor physics of FBRs and ATRs and other fundamental studies, and the operation of JRR-2, JRR-4 and JMTR are reported.

    As a part of the Reduced Enrichment Research and Test Reactor (RERTR) program in JAERI, the enrichment reduction for Japan Research Reactor 4 (JRR-4) is in progress. A fuel element using a 19.75 % enriched UAlx-Al dispersion type with a uranium density of 2.2 g/cm 3 was designed as the LEU fuel and the neutronic and thermo-hydraulic performances of the LEU core were compared with those of the current HEU core. The results of the neutronic design are as follows: (1) the excess reactivity of the LEU core becomes about 1 % Δk/k less, (2) the thermal neutron flux in the fuel region decreases about 25 % on the average, (3) the thermal neutron fluxes in the irradiation pipes are almost the same and (4) the core burnup lifetime becomes about 20 % longer. The thermo-hydraulic design also shows that: (1) the fuel plate surface temperature decreases about 10 deg C due to the increase of the number of fuel plates and (2) the temperature margin with respect to the ONB temperature increases. Therefore, it is confirmed that the same utilization performance as the HEU core is attainable with the LEU core. (author)

  14. Nuclear calculation for employing medium enrichment in reactors of Japan Atomic Energy Research Institute

    1979-01-01

    The fuel used for the research reactors of Japan Atomic Energy Research Institute (JAERI) is presently highly enriched uranium of 93%. However, the U.S. government (the supplier of fuel) is claiming to utilize low or medium enriched uranium from the viewpoint of resistivity to nuclear proliferation, and the availability of highly enriched uranium is becoming hard owing to the required procedure. This report is described on the results of nuclear calculation which is the basis of fuel design in the countermeasures to the reduction of enrichment. The basic conception in the reduction of enrichment is three-fold: to lower the latent potential of nuclear proliferation as far as possible, to hold the present reactor performance as far as possible, and to limit the reduction in the range which is not accompanied by the modification of reactor core construction and cooling system. This time, the increase of the density and thickness of fuel plates and the effect of enrichment change to 45% on reactivity and neutron flux were investigated. The fuel of UAl sub(x) - Al system was assumed, which was produced by powder metallurgical method. The results of investigations on JRR-2 and JMTR reactors revealed that 45% enriched fuel does not affect the performances much. However, deterioration of the performances is not neglegible if further reduction is needed. In future, the influence of the burn-up effect of fuel on the life of reactor cores must be investigated.

    The results of works, accomplished by the Japanese Atomic Energy Research Institute, related to evaluation of the nuclear facilities effect on the environmental medium, are considered. The analytical results of studies on the environmental radioactivity with an account of meteorological aspects, evaluation of the nuclear facilities impact on the environmental medium are presented. Studies on the radionuclide behavior in the environmental medium cover large range of problems: distribution of natural and artificial radionuclides in the surface medium and their migration; evaluation of the human radiation doses on the account of radionuclides; environmental medium protection and risk evaluation. The method for measuring the 90 Sr concentrations with application of ion-exchange tars and a simple method for determining the radon activity with application of liquid scintillators were developed in the process of the study on creation of the environmental medium monitoring. The studies, related to the content and behavior of tritium, Pu, 137 Cs, 247 Am, as well as mercury and other heavy metals in the environmental medium were carried out. The methods for evaluating the NPPs radiation effect on the population with an account of the radioactive substances releases both by normal operation and in the emergency situations, were developed. Attention is also paid to research programs and developed codes [ru

    1977-01-01

    Research and development on uranium enrichment by the gaseous diffusion process have been carried out by the Japan Atomic Energy Research Institute, the Institute of Physical and Chemical Research, and industries since 1965. The paper describes the two important keys to reducing the cost of uranium separation. One is the characteristics of barriers and the other is financing and/or political planning. The techniques of preparing a barrier with pore diameter 40A have been developed with polytetrafluoroethylene (PTFE), alumina and nickel. Experiments on corrosion behaviour have indicated that PTFE barriers are the most favourable. In the field of engineering research, the adiabatic efficiency of the axial compressor for UF 6 was raised to as high as 90% by long-term operation tests. Based on these experimental data, technico-economic evaluation of a uranium enrichment plant was carried out for optimization of separation efficiency, number of steps and plant operating conditions. Sensitivity in the separation cost was calculated as a function of pore diameter, cost of uranium hexafluoride, plant capacity, cost of electric power, and annual expenditure of the plant. A finance plan must be such as to achieve: (a) maximization of debt in a percentage of total capital; (b) off-take contracts to utilities as security for financing; (c) minimization of risks to equity and achievable cost of capital. Therefore, the cash flow analysis and the schedule for construction and operation are very important for the economic feasibility of a uranium enrichment plant. To minimize the risk, the economic as well as the political environment is important. Government support and international agreements are necessary. (author)

    The tandem accelerator in Japan Atomic Energy Research Institute was made by NEC in USA. Since it is the accelerator of turning-up structure, it has large magnet at the high voltage terminal, and supplies electric power by driving a generator with large diameter shaft. The control is carried out by CAMUCK, and the electronic circuit is protected from the surging arising due to discharge. Since the experiment on full scale was begun, 14 years have elapsed, and at present, it became a very stable accelerator. As to the operation mode, the acceleration voltage is limited to below 17 MV. The operation voltage and the state of operation are shown. Recently, the troubles of chains originating in oil have occurred. The adjustment of the tandem accelerator requires more than one month. The adjustment is mainly related to the chains and shafts, and this is explained. The ion source used for the tandem accelerator at present is the negative ion source made by NEC. The installation of an ECR ion source is planned. The utilization of the tandem accelerator system is reported. (K.I.)

    The Metal Mining Agency of Japan and VNIITSVETMET have agreed on March 15, 1995 on the joint research plan to use environment preserving technologies in extracting valuable metals from low-grade ores and tailings. The present study developed methods that use leaching, solvent extraction and electrolytic extraction. Flotation mineral processing tests were performed by using sulfurous acid, sodium sulfite and hot water bubbles. In the test using the bacteria leaching method, observations were performed on effects due to bacteria culturing conditions, conditions affecting the leaching, effects due to pH adjustment, effects due to impalpable powder activated carbon, effects due to coarse powder activated carbon, electrochemical properties of activated carbon, and bacteria observation using a scanning electron microscope. The chemical leaching, solvent extraction and electrolytic extraction tests were carried out on chemical leaching of bulk-separation flotation froth of Zhezkent tailing, solvent extraction using a small mixer settler, a stripping test, and electrolytic extraction efficiency. For waste water treatment, tests were executed using iron oxidizing bacteria. (NEDO)

    A rust layer, so called 'protective' rust layer, on a weathering low-alloy steel has strong protective ability for atmospheric corrosion of the steel. We have recently found through a large number of spectroscopic studies including Moessbauer spectroscopy that the protective rust layer forms after long-term phase transformation. The phase and structure of the rust definitely control the protective ability of the rust layer. From this recent knowledge, some new technologies have been developed. One is the surface-treatment technique that provides a possibility for obtaining the protective rust layer in a relatively short period even in the severe environments such as in marine and chloride (de-icing salts) containing environments. Others are based on selection of effective alloying elements for steel materials. These are particularly important for application in areas where protective rust layer formation may be hindered or prevented. In this paper, we mention recent progress in research and development on rusting protection by rust for atmospheric corrosion of steels in Japan.

    Humans have evolved into what they are today after the passage of 6-7 million years. If we define the beginning of urbanization as the rise of the industrial revolution, less than 0.01% of our species' history has been spent in modern surroundings. Humans have spent over 99.99% of their time living in the natural environment. The gap between the natural setting, for which our physiological functions are adapted, and the highly urbanized and artificial setting that we inhabit is a contributing cause of the "stress state" in modern people. In recent years, scientific evidence supporting the physiological effects of relaxation caused by natural stimuli has accumulated. This review aimed to objectively demonstrate the physiological effects of nature therapy. We have reviewed research in Japan related to the following: (1) the physiological effects of nature therapy, including those of forests, urban green space, plants, and wooden material and (2) the analyses of individual differences that arise therein. The search was conducted in the PubMed database using various keywords. We applied our inclusion/exclusion criteria and reviewed 52 articles. Scientific data assessing physiological indicators, such as brain activity, autonomic nervous activity, endocrine activity, and immune activity, are accumulating from field and laboratory experiments. We believe that nature therapy will play an increasingly important role in preventive medicine in the future.

    JAERI has performed cooperative researches with several Japanese organizations utilizing the Halden Boiling Heavy Water Reactor(HBWR) which is located at Halden in Norway. These researches are carried out based on the contracts of the cooperative researches, which are revised every three years, in accordance with the renewal of the participation of JAERI to the OECD Halden Reactor Project. This report summarizes the objectives, contents and outlines of the achievements of the cooperative researches during the three years from 2000 January to 2002 December. During the period, seven cooperative researches had been carried out. Two of them had been completed and other five researches have been continued to the next three-year period. Most of them are irradiation test researches of advanced fuel and cladding in order to prepare the higher burnup utilization and introduction of LWR fuel and MOX fuel in LWRs of Japan. As the researches of fuel irradiation usually take long time for preparing test and irradiation, three years are usually not enough to obtain some achievements from the irradiation tests. Therefore, five cooperative researches have been continued to the next three-year period. In this report, the achievements of the researches continued to the next period are not final one but a kind of progress report. (author)

    Even though most clinical data on cachexia have been reported from Western countries, cachexia may be a growing problem in Asia as well, as the population in this area of the world is considerably larger. Considering the current definitions of obesity and sarcopenia in Japan, which are different from the ones in Western countries, the lack of a distinct cachexia definition in Japan is strinking. Only one epidemiological study has reported the prevalence of cachexia using weight loss as part of the definition in patients with stage III or IV non-small cell lung cancer. Although the reported prevalence of 45.6% is within the range of that in Western countries (28-57% in advanced cancer), we cannot compare the prevalence of cachexia in other types of cancer, heart failure, chronic obstructive pulmonary disease (COPD), and kidney disease (CKD) between Japan and Western countries. In patients with heart failure, one third of Japanese patients has a body mass index cachexia in Japan. The rate of underweight patients in COPD has been reported as 31-41% in COPD and seems to be high in comparison to the prevalence of cachexia in Western countries (27-35%). The reported lowest quartile value of BMI (19.6 kg/m 2 ) in CKD may match with the prevalence of cachexia in Western countries (30-60%). The number of clinical trials targeting cachexia is very limited in Japan so far.

    The Second US - Japan Workshop on Global Change: Environmental Response Technologies for Global Change was hosted by the Program on Resources at the East-West Center, in Honolulu, Hawaii on February 1--3, 1993, on behalf of the United States Committee on Earth and Environmental Sciences (CEES) of the Federal Coordinating Council for Science, Engineering, and Technology (FCCSET). This workshop brought together over fifty leading scientists from the two countries to review existing technologies and to identify needed research on the development of new technologies for mitigation and adaptation of global change. The Workshop was organized around three areas of research: (1) capture, fixation/utilization, and disposal of CO{sub 2} (e.g. CO{sub 2}, separation and capture technologies, ocean and land disposal of CO{sub 2}; (2) energy production and conservation technologies to reduce greenhouse gas emissions (e.g. combustion efficiency, non-carbon based energy technologies, energy conservation technologies); and (3) adaptation technologies and practices related to global climate change (e.g., adaptation responses of crops to climate change, adapting urban infrastructure for climate change). Priorities for joint research in each of these areas were discussed. Selected papers have been processed separately for inclusion in the Energy Science and Technology Database.

    At 2:46 pm on March 11, 2011, a huge earthquake (M 9.0) occurred off the Pacific coast of Tohoku Region, Japan. The subsequent Tsunamis hit the coasts and seriously damaged fishing villages and towns in the area. Tohoku Region faces Northwestern Pacific where is one of the most productive oceans on the Earth. Then, what happened to the marine ecosystems in the Tohoku Region? What happened to the fishery bioresources? What is the mechanism to sustain high productivity in the Region? Is the ecosystem restoring after 4 years? What is required for the recovery of fisheries in the area? In order to answer these questions, the 10 years research project, TEAMS (Tohoku Ecosystem-Associated Marine Sciences) was launched in January 2012 funded by MEXT (Ministry of Education, Culture, Sports, Science and Technology, Japan) to conduct comprehensive research on the area. Tohoku University (TU), Atmosphere and Ocean Research Institute, the University of Tokyo (AORIUT), Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and 25 other institutions are conducting research for this project in close association with local government and fishery people. Currently, approximately 400 people (200 scientists, 160 students and others) covering physical, chemical, biological, and geological sciences including modeling take part in the project from all over Japan. MEXT also supports TEAMS by constructing R/V Shinsei Maru in 2013 for the oceanic investigations in the region. In this report, the overview of the ecosystem before and after the disaster, major findings and challenges of TEAMS will be described.

    To investigate how and why Japan Tobacco, Inc. (JT) in 1986 established the Smoking Research Foundation (SRF), a research-funding institution, and to explore the extent to which SRF has influenced science and health policy in Japan. We analysed documents in the Truth Tobacco Industry Documents archive, along with recent Japanese litigation documents and published documents. JT's effort to combat effective tobacco control was strengthened in the mid-1980s, following privatisation of the company. While remaining under the protection of Japan's Ministry of Finance, the semiprivatised company lost its 'access to politicos', opening up a perceived need for collaboration with global cigarette makers. One solution, arrived at through clandestine planning with American companies, was to establish a third-party organisation, SRF, with the hope of capturing scientific and medical authority for the industry. Guarded by powerful people in government and academia, SRF was launched with the covert goal of influencing tobacco policy both inside and outside Japan. Scholars funded by SRF have participated in international conferences, national advisory committees and tobacco litigation, in most instances helping the industry to maintain a favourable climate for the continued sale of cigarettes. Contrary to industry claims, SRF was never meant to be independent or neutral. With active support from foreign cigarette manufacturers, SRF represents the expansion into Asia of the denialist campaign that began in the USA in 1953. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Following the Kyoto demands the budgets allocated to the renewable energies researches are more and more important. Among these energies the biomass is very popular in Japan because it does not increase the carbon dioxide level in the atmosphere. Since the years 1990 the Japan implemented three ministries to promote the biomass energy in the country. This document presents the biomass situation in the world and more specially in the Japan and the researches programs with the NEDO, the New Energy and Industrial Technology Development Organization).

    Full text: Nuclear power accounts for about 35% electric power generation in Japan, playing an important role of energy supply. In addition, a commercial scale reprocessing plant is under construction. A real nuclear fuel cycle is imminently close at hand in Japan. COP3 in Kyoto in 1997 called for every country's fight against global warming. Nuclear power in Japan is expected to take another important role from this viewpoint, too. In order to play these expected roles, it is absolutely needed to preserve nuclear talented experts, by maintaining, succeeding and newly developing nuclear technologies. The Atomic Energy Commission of Japan also points out in its report on 'Long-Term Program for Research, Development and Utilization of Nuclear Energy' that research-and development activities are very important to motivate young researchers and engineers who might choose to take nuclear careers. However, young generation capable students seem to avoid majoring nuclear engineering in view of nuclear industry uncertainties in future caused by stagnated Japanese economy since 1990, liberalization of electricity markets, future electricity demand modest forecasts, matured light water reactor technologies, and repeated nuclear accidents inside and outside the country, etc. Aging research facilities at universities are another de-motivating element of causing the reduction of qualifiable students. Consequently, preservation of knowledge and expertise is becoming a big concern for future. According to the survey conducted by the Japan Atomic Industrial Forum (JAIF) over two years since 2002, participated by the members from nuclear industries, universities, research organizations, electricity industries, nuclear plant suppliers and construction contractors, as well as the questionnaire sent to students, there are various issues for preservation of nuclear talented experts in Japan. Although the number of graduates on nuclear engineering is actually about 350 every year, and

    Scholarly attention to pharmaceutical companies' ability to sustain research and development (R&D) productivity has increased as they increasingly handle business challenges. Furthermore, the deterioration of R&D productivity has long been considered a major cause of mergers and acquisitions (M&As). This study attempts to investigate quantitatively the possible causes of the deterioration and the relationship between the deterioration and M&As by examining the Japanese pharmaceutical industry. Japan from 1980 to 1997 is an ideal case because of the availability of official data, but more importantly the significant changes in its business environment at the time. Using the Malmquist Index and data envelopment analysis, we measured the deterioration of R&D productivity from 1980 to 1997 based on a sample of 15 Japanese companies. Two lessons can be learned from Japan's case. First, to sustain R&D productivity over the long term, companies should use licensing activities and focus on the dominant therapeutic franchises. Second, if a company fails significantly to catch up with the benchmark, it is likely to pursue an M&A or seek an alternative way to improve R&D productivity. These findings appear similar to the current situation of the global pharmaceutical industry, although Japan pursued more licensing activities than M&A to improve R&D productivity.

    Yamada, Katsumi; Oka, Yoshiaki

    2005-01-01

    The SCWR is an innovative LWR operating at supercritical pressure with a once-through direct cycle. It has the potential advantage of low capital cost due to its high thermal efficiency and substantial plant system simplifications. This paper outlines the completed and on-going R and D in Japan, and describes plans of the next phase projects for SCWR development. The concept was born at the University of Tokyo fifteen years ago. After a feasibility study by an industry team, a project for key technology development and plant conceptual design was launched in fiscal year (FY) 2000 funded by METI, followed by another project for fundamental study on supercritical water chemistry under radiation field and an I-NERI project for material development, and was completed in FY 2004 presenting an SCWR plant concept. To advance and optimize the plant concept, a new project is proposed in Japan. In addition, another project for developing the SCWR with fast spectrum core is proposed. The SCWR concept has acquired worldwide interest and was selected as one of the six Generation IV nuclear energy systems under GIF Program in FY 2002, and international collaboration for the SCWR RD and D is being established with an aggressive target of constructing a prototype reactor in the next fifteen years. The projects in Japan are expected to promote the development of the SCWR and to contribute the GIF activities. (author)

    1989-01-01

    The ''Long-term Program for Development and Utilization of Nuclear Energy'' by Japan Atomic Energy Commission (JAEC) plans to develop fast breeder reactors (FBRs) as the mainstay of Japan's future nuclear power generation. For the development of the FBR, the main principle is to pursue the establishment of FBR plutonium utilization systems, which are superior to the LWR uranium utilization systems. The above program also states as follows: ''Incessant efforts, with proper co-operation of the public and private sectors, will be required for a considerably long time for FBR development, and the concrete measures to be implemented in this connection will be discussed, hereafter, in continuation at the Advisory Committee on FBR Development Program of the Atomic Energy Commission''. It was clearly stated in the ''Long-term Program'' that utilities would play a leading role in the design, construction, and operation of DFBRs to follow ''Monju''. They have entrusted Japan Atomic Power Company (JAPC) with the above tasks. Technical verification and demonstration tests for seismic design and feasibility studies of main components are being conducted with government support. Regarding the nuclear fuel cycle, PNC has been developing FBR fuel reprocessing technologies. Currently, the Recycle Equipment Test Facility (RETF) is being designed to conduct engineering-scale tests. A pilot plant is planned to start operation after 2000 assuming positive results of the tests. (author)

    The safe dismantling of a retired nuclear power plant was demonstrated by completion of dismantling activities for the Japan Power Demonstration Reactor (JPDR), March, 1996, which had been conducted since 1986. This project was a flag ship project for dismantling of nuclear power plants in Japan, aiming at demonstrating an applicability of developed dismantling techniques in actual dismantling work, developing database on work activities as well as dismantling of components and structures. Various data on dismantling activities were therefore systematically collected and these were accumulated on computer files to build the decommissioning database; dismantling activities were characterized by analyzing the data. The data analysis resulted in producing general forms such as unit activity factors, for example, manpower need per unit weight of component to be dismantled, and simple arithmetic forms for forecasting of project management data to be applied to planning another dismantling project through the evaluation for general use of the analyzed data. The results of data analysis could be usefully applied to planning of future decommissioning of commercial nuclear power plants in Japan. This report describes the data collection and analysis on the JPDR dismantling activities. (author)

    Duchenne muscular dystrophy (DMD) is the most commonly inherited neuromuscular disease. Therapeutic agents for the treatment of rare disease, namely "orphan drugs", have recently drawn the attention of researchers and pharmaceutical companies. To ensure the successful conduction of clinical trials to evaluate novel treatments for patients with rare diseases, an appropriate infrastructure is needed. One of the effective solutions for the lack of infrastructure is to establish a network of rare diseases. To accomplish the conduction of clinical trials in Japan, the Muscular dystrophy clinical trial network (MDCTN) was established by the clinical research group for muscular dystrophy, including the National Center of Neurology and Psychiatry, as well as national and university hospitals, all which have a long-standing history of research cooperation. Thirty-one medical institutions (17 national hospital organizations, 10 university hospitals, 1 national center, 2 public hospitals, and 1 private hospital) belong to this network and collaborate to facilitate clinical trials. The Care and Treatment Site Registry (CTSR) calculates and reports the proportion of patients with neuromuscular diseases in the cooperating sites. In total, there are 5,589 patients with neuromuscular diseases in Japan and the proportion of patients with each disease is as follows: DMD, 29 %; myotonic dystrophy type 1, 23 %; limb girdle muscular dystrophy, 11 %; Becker muscular dystrophy, 10 %. We work jointly to share updated health care information and standardized evaluations of clinical outcomes as well. The collaboration with the patient registry (CTSR), allows the MDCTN to recruit DMD participants with specific mutations and conditions, in a remarkably short period of time. Counting with a network that operates at a national level is important to address the corresponding national issues. Thus, our network will be able to contribute with international research activity, which can lead to

    This paper reviews Kudoh Takeki's activity critically during the colonial Korea period, regarding his research on Medical Science and Japanized Confucianism. He managed 'The Seoul Gynecological Hospital'for approximately 35 years in the Chosŏn period as a Japanese resident with Chosŏn status. He published medical knowledge about obstetrics through more than 280 articles, and attempted to improve the hygiene and health of 'Korean Women'. He tried to complete his will toward 'One Unity of Chosŏn and Japan'by terminating the Chosŏn culture 'gene'as an intention. The purpose would enlighten Chosŏn by Japanese blessing. This paper aims to confirm his intention by two aspect of analysis by 'Medical Science'as an occupation and 'Confucianism'and the background of his thought. The content of Kudoh Takeki's research in Chosŏn regarding Medical Science-Confucianism is described as below. First, the purpose and mission of Kudoh Takeki regarding Chosŏn was analyzed. The papers revealed the Kudoh Takeki mentioned only the 'HusbandMurders of Corean Women', which was defined by Kudoh Takeki as 'A Special Crime of Corea'. This paper examined his intensions. Second, writings by Kudoh Takeki were listed to verify the 'medical'field and 'non-medical'field according to the subject. No list of contents was found for his more than 280 articles or essays in magazines/newspapers/ publications, and these papers only described the Kudoh paper "A Special Crime of Corea"and studied the separate book publication by Kudoh THE GYNAECOLOGICAL RESEARCH OF HUSBANDMURDERS OF COREAN WOMEN, A SPECIAL CRIME OF COREA. Third, the genealogy of Confucianism of Kudoh Takeki was analyzed as his background of mental·thought by his hometown and the school he graduated from. The people from Kumamoto and Seiseiko school who were influenced by 'Yi Toegye'of Chosŏn Confucianism were more active than general Japanese. Fourth, the practical activity of Kudoh Takeki in Chosŏn was described. The paper

  4. The Medical Anthropologist as the Patient: Developing Research Questions on Hospital Food in Japan through Auto-Ethnography

    Full Text Available I was an inpatient at a small maternity clinic in Japan in 2012–13 and found it impossible to separate the way I experienced medical care and my training as a medical anthropologist. As I was encouraged to eat and monitor my weight so that I would “grow” a healthy baby, I recalled how interviewees from my HIV/AIDS project described nourishing their bodies so they could fight disease. Because of my experience in the healthcare system in Japan, I ended up reframing my data to add questions about the role of hospital food in patient care. Meanwhile, I developed the social networks necessary to execute a new project, which I would later undertake. In this essay I argue that medical anthropologists working from a phenomenological perspective may regard their own bodies as assets rather than hindrances in research, and that because bodies are gendered, focusing on this facet of habitus can be particularly informative. I also illustrate how systematic reflection on personal experience in the field (autoethnography aids in the development of research questions and reframing data. Finally, I discuss how highlighting these steps in research methods courses can demystify the research process for students.

    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 Japanese word "kimono" is well-known in the West. The most important vector for this knowledge of the kimono was the trend of Japonism that emerged in the second half of the 19th century after Japanese ports were opened to the world. In order to study the influence of the kimono on Western culture in the context of Japonism, we conducted field surveys to confirm that kimonos from Japan were present in Europe.This was a period when Japanese goods were taken overseas in increasing numbers. ...

    Biomedical HIV prevention strategies are playing an increasingly prominent role in addressing HIV epidemics globally, but little is known about their use in Japan, where persistent HIV disparities and a recently stable, but not declining, national epidemic indicate the need for evolving approaches. We conducted an ethnographic study to determine the context of pre-exposure prophylaxis (PrEP) and postexposure prophylaxis (PEP) use and to identify directions for future research and action in Japan. We used data from observational fieldwork in the Kansai region and Tokyo Metropolitan Area (n = 178 persons observed), qualitative interviews (n = 32), documents and web-based data sources (n = 321), and email correspondences (n = 9) in the period 2013-2016. Drug approvals by Japan's regulatory agencies, insurance coverage for medications, and policies by healthcare institutions and government agencies were the main factors affecting PrEP and PEP legality, use, and awareness. Awareness and the observable presence of PrEP and PEP were very limited, particularly at the community level. PrEP and PEP held appeal for Japanese scientists and activists, and for study participants who represented various other stakeholder groups; however, significant concerns prevented open endorsements. Japanese health officials should prioritize a national discussion, weigh empirical evidence, and strongly consider formal approval of antiretroviral (ARV) medications for use in PrEP and both occupational and nonoccupational PEP. Once approved, social marketing campaigns can be used to advertise widely and increase awareness. Future research would benefit from theoretical grounding in a diffusion of innovations framework. These findings can inform current and future ARV-based prevention strategies at a critical time in the international conversation.

    Nuclear power plants in Japan have been fabricated and constructed in compliance with the standards developed by MITI in 1980. These standards were developed as design standards taking aging phenomena during service lifetime into consideration. But these standards do not specify the requirements for flaw evaluation and repair methods, though they include some maintenance requirements. Therefore, MITI decided to develop Maintenance Standards which commensurate with plant age, and entrusted Japan Power Engineering and Inspection Corporation (JAPEIC) with survey of ASME Sec. XI. Draft of Maintenance Standards was developed in March, 1996, and will be legislated by 1999. Structural materials of nuclear power plants would sustain damage owing to cyclic stress, high temperature or neutron irradiation etc. during operation. And damage would change mechanical properties of materials, such as tensile strength, charpy absorption energy, fracture toughness and so on. As integrity of nuclear power station depends on these mechanical properties of materials, it will become very important to be able to evaluate mechanical properties of materials nondestructively especially for older nuclear power plants. These circumstances made MITI entrust JAPEC with verification test to develop nondestructive characterization methods. This verification test started in the 1990 fiscal year and was completed in 1997 fiscal year. (orig./DGE)

  13. Present status of reactor physics in the United States and Japan-III. 1. Recent Activities of Loading Pattern Optimization Research in Japan

    International Nuclear Information System (INIS)

    Yamamoto, Akio

    2001-01-01

    Because of recent enhancements of optimization algorithms and great improvements in computer hardware, loading pattern (LP) optimization methods are being used as practical design tools both in the pressurized water reactor (PWR) and boiling water reactor (BWR) industries. LP optimization methods are mainly used for the following in-core fuel management activities in Japan: 1. minimization of fuel cycle costs; 2. evaluation of various in-core fuel management scenarios; 3. estimation of the number of feed assemblies needed during several successive cycles for fuel ordering; 4. evaluation of fuel bids. Although engineers can perform these analyses, the major motivations to utilize LP optimization methods are the reduction of manpower and the establishment of engineer-independent LP quality. These are important in today's in-core fuel management tasks. In the following sections, activities related to LP optimization research in Japan are briefly described. The major activity of PWR LP optimization research in Japan is development of the INSIGHT system. The INSIGHT system is an integrated scoping analysis tool for PWRs developed by Nuclear Fuel Industries (NFI). The INSIGHT system is a graphical user interface (GUI)-based interactive design tool that includes LP optimization, automated multicycle analysis, an interactive LP design, core follow, an integrated database, and some auxiliary functions. The INSIGHT system was mainly written in the C++ language and consists of ∼400 000 lines of source code. The GALLOP code is the LP optimization module of the INSIGHT system. An automated multicycle analysis is performed by the MCA code in INSIGHT. The MCA code performs a fuel and burnable poison (BP) inventory search by automatically invoking the GALLOP code, which makes LPs. The MCA code can deal with various constraints that have appeared in practical in-core fuel management, e.g., limitations of fuel/BP stock, forced fuel loading/discharge, limitations of core safety

    Japan Atomic Energy Research Institute(JAERI) conducted Piping Reliability Proving Tests from 1975 to 1992 based upon the contracts between JAERI and Science and Technology Agency of Japan under the auspices of the special account law for electric power development promotion. The purposes of those tests are to prove the structural reliability of the primary cooling piping constituting a part of the pressure boundary in the water reactor power plants. The tests with large experimental facilities had ended already in 1990. After that piping reliability analysis by the probabilistic method followed until 1992. This report describes the users manual on databases about the test results using the large experimental facilities. Objectives of the piping reliability proving tests are to prove that the primary piping of the water reactor (1) be reliable throughout the service period, (2) have no possibility of rupture, (3) bring no detrimental influence on the surrounding instrumentations or equipments near the break location. The research activities using large scale piping test facilities are described. The present report does the database about the test results pairing the former report. With these two reports, all the feature of Piping Reliability Proving Tests is made clear. Briefings of the tests are described also written in Japanese or English. (author)

    Previous fundamental studies on the ore genesis of uranium occurrences chiefly in Cenozoic sandstone formations in Japan, have been re-examined as the case history on natural analogue of radionuclides in high-level radioactive wastes (HLRW). Two principal mode of occurrences have been distinguished among Cenozoic uranium localities in Japan. In the Setouchi (Inland Sea) subregion, hot-spots are found in lacustrine to shallow sea facies of calm environment, corresponding to the first stage of formation of tectonic basins. As observed in Ningyo-toge and Tono area, stratabound ore bodies are generally arranged into paleo-channels. Another type of sporadic uranium indications are found within collapse basins in the 'Green-tuff' subregion, where intense volcanisms and block movements had been taken places throughout Middle miocene age. Well-developed fractures were to be favorable paths for uraniferous groundwater, as well as the suitable site for deposition of uranium. In both cases, the source material of uranium is granitic basement. Under oxidizing environment, uranium anomalies have been occasionally detected in surface- or fracture waters which passing through decomposed granite. In contrast to the behavior of uranium, one of the adequate analogues for mobile nuclides, thorium and REE are relatively immobile even under the same geologic and geochemical circumstances. In ore horizon, where reducing condition has still been kept, geochronological age of tetravalent uranium mineral is in concordance with the age of the host rock. Analysis of structural control shows that the principal factors for uranium concentration are the layout of redox front related to paleo-water tables. 234U/238U disequilibrium method has been proved to be the powerful tool for detecting mobility of uranium in the host rock throughout diagenesis and weathering process. The result of field and laboratory works on this is reported as an example. (author)

    Many pharmacoepidemiologic studies using large-scale databases have recently been utilized to evaluate the safety and effectiveness of drugs in Western countries. In Japan, however, conventional methodology has been applied to postmarketing surveillance (PMS) to collect safety and effectiveness information on new drugs to meet regulatory requirements. Conventional PMS entails enormous costs and resources despite being an uncontrolled observational study method. This study is aimed at examining the possibility of database research as a more efficient pharmacovigilance approach by comparing a health care claims database and PMS with regard to the characteristics and safety profiles of sertraline-prescribed patients. The characteristics of sertraline-prescribed patients recorded in a large-scale Japanese health insurance claims database developed by MinaCare Co. Ltd. were scanned and compared with the PMS results. We also explored the possibility of detecting signals indicative of adverse reactions based on the claims database by using sequence symmetry analysis. Diabetes mellitus, hyperlipidemia, and hyperthyroidism served as exploratory events, and their detection criteria for the claims database were reported by the Pharmaceuticals and Medical Devices Agency in Japan. Most of the characteristics of sertraline-prescribed patients in the claims database did not differ markedly from those in the PMS. There was no tendency for higher risks of the exploratory events after exposure to sertraline, and this was consistent with sertraline's known safety profile. Our results support the concept of using database research as a cost-effective pharmacovigilance tool that is free of selection bias . Further investigation using database research is required to confirm our preliminary observations. Copyright © 2018. Published by Elsevier Inc.

    Development was agreed of highly efficient mineral resources extraction and treatment technology as a cooperative R and D project between Japan and Kazakhstan in March, 1995. This paper explains the 1996 results. Kazakhstan is a mineral resources country and has a number of base metal mines. However, as the result of production/treatment processes, a lot of by-products are produced consisting of low grade ores and tailings. These by-products contain a variety of metals. If a process is developed for extracting metals from the by-products, it will contribute to the prevention of environmental pollution caused by mining activities as well as increasing metal production in Kazakhstan. The development begun in 1995 will continue until fiscal 2000. The report describes a sampling method for test specimens, and chemical/mineralogical analysis. Concerning leaching tests for low grade ore, methods are explained covering Cu maximum, column, and flotation froth leaching tests. Also described are leaching tests for tailings. A flotation test and bacteria leaching test are mentioned in addition. The report further refers to the basic study of solvent extraction and treatment of waste water. (NEDO)

    Full Text Available In the world, river basins often interwoven into two or more states or prefectures and because of that, disputes over water are common. Nevertheless, not all shared river basins are associated with water conflicts. Rivers in Japan and Malaysia play a significant role in regional economic development. They also play a significant role as water sources for industrial, domestic, agricultural, aquaculture, hydroelectric power generation, and the environment. The research aim is to determine the similarities and differences between the Sagami and Muda River Basins in order to have a better understanding of the governance needed for effectively implementing the lessons drawn from the Sagami River Basin for improving the management of the Muda River Basin in Malaysia. This research adopts qualitative and quantitative approaches. Semi-structured interviews were held with the key stakeholders from both basins and show that Japan has endeavored to present policy efforts to accommodate the innovative approaches in the management of their water resources, including the establishment of a river basin council. In Malaysia, there is little or no stakeholder involvement in the Muda River Basin, and the water resource management is not holistic and is not integrated as it should be. Besides that, there is little or no Integrated Resources Water Management, a pre-requisite for sustainable water resources. The results from this comparative study concluded that full support and participation from public stakeholders (meaning the non-government and non-private sector stakeholders is vital for achieving sustainable water use in the Muda River Basin. Integrated Water Resources Management (IWRM approaches such as the introduction of payments for ecosystems services and the development of river basin organization in the Muda River Basin should take place in the spirit of political willingness.

    The University of Tsukuba project for boron neutron capture therapy (BNCT) was initiated at the Japan Atomic Energy Research Institute (JAERI) in 1992. The clinical study for BNCT began at the Japan Research Reactor (JRR)-2 of the JAERI in November 1995. By the end of 1998, a new medical irradiation facility had been installed in JRR-4 of that included a new medical treatment room and patient-monitoring area adjacent to the irradiation room. The medical treatment room was built to reflect a hospital-type operation room that includes an operating table with a carbon head frame, anesthesia apparatus with several cardiopulmonary monitors, etc. Following craniotomy in the treatment room, a patient under anesthesia is transported into the irradiation room for BNCT. The boron concentration in tissue is measured with prompt gamma ray analysis (PGA) and simultaneously by inductively coupled plasma atomic emission spectroscopy (ICP-AES) methods. For the immediate pre- and post-BNCT care, a collaborating neurosurgical department of the University of Tsukuba was prepared in the vicinity of the JAERI. The long term follow-up is done at the University of Tsukuba Hospital. Epithermal neutron beam also became available at the new JRR-4. By changing the thickness and/or the configuration of heavy water, a cadmium plate, and a graphite reflector, the JRR-4 provides a variety of neutron beams, including three typical beams (Epithermal mode and Thermal modes I and II). Intraoperative BNCT using the thermal beam is planned to study at the beginning of the clinical trial. The ongoing development of the JAERI Computational Dosimetry System (JCDS) and radiobiological studies have focused in the application of the epithermal beam for BNCT. After obtaining these basic data, we are planning to use the epithermal beam for intraoperative BNCT. (author)

    Highlights: • This paper reports the current status of a safety research on water-cooled fusion DEMO in Japan. • We report analyses of two transients: (i) complete loss of decay heat removal and (ii) major ex-VV LOCA. • The MELCOR analysis has clarified the temperature histories of the DEMO components in complete loss of decay heat removal. • A strategy to reduce the pressure load to the final barrier confining radioactive materials is proposed against the major ex-VV LOCA. - Abstract: This paper reports the current status of a safety research on water-cooled fusion DEMO in Japan. A basic strategy of development of the safety guidelines is described for DEMO based on a water-cooled solid pebble bed blanket. Clarification of safety features of the DEMO in accident situations is a key issue to develop the guidelines. Recent achievements in understanding of the safety features of the water-cooled DEMO are reported. The MELCOR analysis has clarified the temperature histories of the DEMO components in a complete loss of decay heat removal event. The transient behavior of the first wall temperature is found to be essentially different from that of ITER. The pressure load to the tokamak cooling water system vault (TCWSV) is analyzed based on a simple model equation of the energy conservation. If the amount of the primary coolant is the same as that of Slim-CS, the previous small Japanese DEMO, the discharged water does not damage the TCWSV with the volume and pressure-tightness similar to those of pressurized light water reactors. It is shown that implementation of a pressure suppression system to the small TCWSV is effective to suppress the pressure load to the second confinement barrier.

    For low- and medium-level waste treatment, main efforts have been put on the reduction of waste volume. For high-level wastes, studies are being carried out on the solidification and partitioning techniques in preparation for completion of the fuel cycle in Japan. For sea disposal of low-level wastes planned by the JAEC, significant information has been obtained regarding integrity and leaching behavior of cement solidified wastes. This paper describes the present status of development of the techniques in the following sections; 1. Treatment of Low- and Medium-Level Wastes; an incinerator with two stage ceramic filters has been tested, and the decontamination factor was found to be 10 4 for various nuclides; reverse osmosis method with a cellulose acetate membrane has been tested for laundry liquid waste, and 60 Co was removed more than 99% together with detergents; and solidification products of spent ion-exchange resin with polyethylene have been proved to be superior in mechanical properties, water resistance and volume reduction to asphalt products. 2. Safety Evaluation of Cement Solidified Wastes for Sea Disposal; homogeneous cement-solidified wastes in 200 l sealed drums did not show any cracks or defects under high hydrostatic pressure; the leaching ratio of 137 Cs for the first one year was estimated to be lower than 0.3%. 3. Treatment of High-Level Wastes; vitrification using natural zeolite has been developed and properties of the products were proved to be excellent; and a partitioning procedure consisting mainly of solvent extraction and ion-exchange method has been studied; reduction of the amount of alkaline agent by introducing a denitration technique, and reduction of resin volume by adopting a porous type resin were achieved

    Background Leftover samples obtained during autopsies are extremely important basic materials for forensic research. However, there are no established practices for research-related use of obtained samples. Objective This study discusses good practice for the secondary use of samples collected during medicolegal autopsies. Methods A questionnaire was posted to all 76 departments of forensic medicine performing medicolegal autopsies in Japan, and 48 responses were received (response rate: 63.2%). As a secondary analysis, we surveyed information provided on department websites. Results Ethical reviews conducted when samples were to be used for research varied greatly among departments, with 21 (43.8%) departments reporting 'fundamentally, all cases are subject to review', eight (16.7%) reporting 'only some are subject to review' and 17 (39.6%) reporting 'none are subject to review'. Information made available on websites indicated that 11 departments had a statement of some type to bereaved families about the potential research use of human samples obtained during autopsies. Nine of these included a notice stating that bereaved families may revoke their consent for use. Several departments used an opt-out system. Conclusion There is no common practice in the field of legal medicine on the ethical use for medical research of leftover samples from medicolegal autopsies. The trust of not only bereaved families but also society in general is required for the scientific validity and social benefits of medical studies using leftover samples from medicolegal autopsies through the use of opt-out consenting and offline and online dissemination and public-relations activities.

    In April 1999, the Fuel Safety Research Laboratory was newly established as a result of reorganization of the Nuclear Safety Research Center, JAERI. The laboratory was organized by combining three laboratories, the Reactivity Accident Laboratory, the Fuel Reliability Laboratory, and a part of the Sever Accident Research Laboratory. Consequently, the Fuel Safety Research Laboratory is now in charge of all the fuel safety research in JAERI. Various types of experimental and analytical researches are conducted in the laboratory by using the unique facilities such as the Nuclear Safety Research Reactor (NSRR), the Japan Material Testing Reactor (JMTR), the Japan Research Reactor 3 (JRR-3) and hot cells in JAERI.

    At the Miyazaki test track today, the new test vehicle, MLU002N, is under test run to obtain necessary data for Yamanashi test track where the construction is underway, the test vehicle has been ordered and the first tunnel was completed in December 1993. Superconducting magnetohydrodynamic drive ship, MHDS, 'Yamato 1' has completed its experiment in 1992 and it is now under preparation to exhibit to the public in___1994. Furthermore, to promote the research development of MHDS, the detailed discussion is underway on the magnetohydrodynamic drive equipment as well as the research on the future scheme. Neither an automobile nor railway but a new transport system called EQUOS LIM CAR(ELC) has been proposed. By using the rotating magnetic field, it will levitate on the aluminum like reaction plate. On the normal road, it will run by rolling the wheels like an electric car but on the highway, it will levitate on the guideway resulting to less noise, less vibration and pollution free drive. To understand the concept of the ELC, the model was built and experimented by using permanent magnet. The same model was donated to the MUSEUM OF SCIENCE AND INDUSTRY in Chicago and was displayed to the public. Today, the trial superconducting magnet has been made and the research development of the subsystem is underway. Research development of superconducting elevator, equipment for the launching of spaceship, tube transportation system and others are in progress for the superconducting applied transportation system.

    DNR is the technique to obtain radiography image continuously using a imaging system and Japan is the leading country in this field. Considering that no research has been performed to obtain quantitative parameters using DNR in Korea, it was necessary to establish a cooperative structure with Japanese experts and to develop the DNR technique throughout this project. The objectives of the project were to conduct 4 cooperative experiments using the HANARO BNCT facility and to establish a relationship with Japanese experts which makes it possible to maintain continuous communication. 4 experiments such as the void fraction and flow pattern measurement in a channel simulating HANARO fuel channel, observation of flow field in Pb/Bi field and the observation of cavity in a diesel engine nozzle were successfully completed. Also, the continuos communication and cooperation between the experts of two countries will be made. In this sense, this project is believed as a model project to use the mega research facility such as HANARO for the international cooperation

    Typhoons are the most devastating weather system occurring in the western North Pacific and the South China Sea. Violent wind and heavy rainfall associated with a typhoon cause huge disaster in East Asia including Japan. In 2013, Supertyphoon Haiyan struck the Philippines caused a very high storm surge and more than 7000 people were killed. In 2015, two typhoons approached the main islands of Japan and severe flood occurred in the northern Kanto region. Typhoons are still the largest cause of natural disaster in East Asia. Moreover, many researches have projected increase of typhoon intensity with the climate change. This suggests that a typhoon risk is increasing in East Asia. However, the historical data of typhoon include large uncertainty. In particular, intensity data of the most intense typhoon category have larger error after the US aircraft reconnaissance of typhoon was terminated in 1987.The main objective of the present study is improvements of typhoon intensity estimations and of forecasts of intensity and track. We will perform aircraft observation of typhoon and the observed data are assimilated to numerical models to improve intensity estimation. Using radars and balloons, observations of thermodynamical and cloud-microphysical processes of typhoons will be also performed to improve physical processes of numerical model. In typhoon seasons (mostly in August and September), we will perform aircraft observations of typhoons. Using dropsondes from the aircraft, temperature, humidity, pressure, and wind are measured in surroundings of the typhoon inner core region. The dropsonde data are assimilated to a cloud-resolving model which has been developed in Nagoya University and named the Cloud Resolving Storm Simulator (CReSS). Then, more accurate estimations and forecasts of the typhoon intensity will be made as well as typhoon tracks. Furthermore, we will utilize a ground-based balloon with microscope camera, X-band precipitation radar, Ka-band cloud radar

    Japanese basic policy regarding disposal of high-level radioactive waste (HLW) is to solidify it into stabilized form, to store it for 30-50 years to be cooled, and to dispose of it deep to the underground (geological disposal). In Japan, reference to P and T technology for long-lived and other nuclides first appeared in the Long-term Programme for Nuclear Research, Development and Utilisation (or 'long-term nuclear programme') back in 1972. That programme noted the need for research and development in order to ensure effective processing of radioactive waste. The long-term nuclear programme issued in 1987 stated that P and T technology was very important from the viewpoint of recycling HLW and enhancing disposal efficiency. It also stated that systematic R and D would be carried out jointly by JAERI, the Power Reactor and Nuclear Fuel Development Corp. (PNC, now JNC) and others. The long-term nuclear programme issued in 1994 stated that each research institute would carry out basic studies on P and T technologies and evaluate each technology at some time in the mid- 1990's to determine how to proceed thereafter. Based on the evaluation schedule stated in this program, the AEC's Advisory Committee on Nuclear Fuel Cycle Back-end Policy investigated and considered matters concerning P and T technology for long-lived and other nuclides. In March 2000, the Committee issued a report entitled 'Research and Development of Technologies for Partitioning and Transmutation of Long-lived Nuclide Status and Evaluation Report'. A brief summary of this report is presented

    In this study, we investigated the status of researching drug information online, and the type of Internet user who uses anonymous Web communities and websites. A Web-based cross-sectional survey of 10875 male and female Internet users aged 16 and over was conducted in March 2010. Of 10282 analyzed respondents, excluding medical professionals, about 47% reported that they had previously searched the Internet for drug information and had used online resources ranging from drug information search engines and pharmaceutical industry websites to social networking sites and Twitter. Respondents who had researched drug information online (n=4861) were analyzed by two multivariable logistic regressions. In Model 1, the use of anonymous websites associated with age (OR, 0.778; 95% CI, 0.742-0.816), referring to the reputation and the narrative of other Internet users on shopping (OR, 1.640; 95% CI, 1.450-1.855), taking a prescription drug (OR, 0.806; 95% CI, 0.705-0.922), and frequent consulting with non-professionals about medical care and health (OR, 1.613; 95% CI, 1.396-1.865). In Model 2, use of only anonymous websites was associated with age (OR, 0.753; 95% CI, 0.705-0.805), using the Internet daily (OR, 0.611; 95% CI, 0.462-0.808), taking a prescription drug (OR, 0.614; 95% CI, 0.505-0.747), and experience a side effect (OR, 0.526; 95% CI, 0.421-0.658). The analysis revealed the profiles of Internet users who researched drug information on social media sites where the information providers are anonymous and do not necessarily have adequate knowledge of medicine and online information literacy.

    In this paper, recent investigations and researches on pollinosis are summarized as centering on the investigation entrusted by the Ministry of Health and Welfare and executed since 1992, and especially the surveys on Japanese cedar pollinosis during 1995 to 1996. The quantity of pollen surveyed in 1995 is the greatest in the survey history of nationwide flying pollen. Particularly, the quantity of cedar and hinoki pollen is 10 to 40 times as many as that in the year before. Consequently, since the sensitization and onset due to the cedar pollen increased greatly, the objects of the surveys and the researches were mainly in respect to the analysis of onset factors of pollinosis, clarification of its natural process, evaluation on the effectiveness of desensitization therapy, the clinical subjects including the confirmation of pharynx symptom and asthma symptom, and the discovery of naturally sensitizing dog. A fact that the quantity of flying pollen concerns the occurrence and degree of the clinical symptom has already been indicated by a clinical observation carried out for a long period of time. In respect to specific prophylaxis and therapy, for the first time the pollen masks and glasses sold on the market are investigated, and the necessity of the verification thereof is described. 27 refs., 7 figs., 5 tabs.

    The first Japanese ethics committee for biomedical research involving human subjects was established at Tokushima University in 1982. Although this committee was not formed as a response to national directives, the government eventually developed ethical guidelines, such as the Ethical Guidelines for Clinical Studies that were established in 2003. The practical impact of such guidelines was a rapid increase in the number of protocols seeking ethics committee approval and, accordingly, an increase in the workload of ethics committees. This review describes the activity of the ethics committee at Tokushima University during the last thirty years and discusses the infrastructure that best supports the activities of this committee. In addition, we address the issues that ethics committees now face and discuss future directions. J. Med. Invest. 62: 114-118, August, 2015.

    1977-01-01

    Research and development works on uranium enrichment by gaseous diffusion process were carried out by JAERI, IPCR and industries since 1965. There are two important keys to reduce the uranium separation cost. One is the characteristics of the barrier and the other is financing and/or political planning. The technics to prepare the barrier with pore diameter of 40A have been developed with polytetrafluoroethylene, alumina and nickel. The experiment on corrosion behavior of PTFE barriers has shown better characteristics than the others. In the field of engineering research, the adiabatic efficiency of axial compressor for UF 6 was resulted to as high as 90% by long term operation tests. Based on these experimental data, techno-economic evaluation on a uranium enrichment plant was carried out with regard to the optimization of separation efficiency, numbers of step and operating conditions of the plant. Sensitivity in the separation cost were calculated as a function of pore diameter, uranium hexafluoride cost, plant capacity, electric power cost, and the plant annual expenditure. A financing plan must be such as to achieve 1. maximization of debt in a percentage of total capitalization 2. off-take contracts to utilities as security for financing 3. minimization of risks to equity and achievable cost of capital. Therefore the cash flow analysis and the schedule for construction and operation are very important for a economical feasibility of a uranium enrichment plant. To minimize the risk, not only economical but also political environment are important. The governmental supports and international agreements will be necessary

    The Mizunami Underground Research Laboratory (MIU) is located in Tono area in Central Japan. It is operated by the Japan Atomic Energy Agency (JAEA) with the main purpose of providing scientific basis for the research and development of technologies needed for deep geological disposal of radioactive waste in fractured crystalline rocks. The current work is focused on the research and experiments in the tunnel located at 500 m depth. The data collected in the tunnel and exploratory boreholes were shared with the participants of the DEvelopment of COupled models and their VALidation against EXperiments (DECOVALEX), an international research and model comparison collaboration. This study describes the development of the fracture model representing granite rocks around the research tunnel. The model domain is 100x150x100m with the main experimental part of the tunnel, Closure Test Drift, located approximately in the center. The major input data were the fracture traces measured on the tunnel walls (total of 2,023 fractures), fractures observed in the horizontal borehole parallel to the tunnel, and the packer tests conducted in this borehole and one vertical borehole located within the modeling domain. 78 fractures (the ones with the inflow) in the tunnel were incorporated in the development of the fracture model. Fracture size was derived from the fracture trace analysis. It was shown that the fracture radius followed lognormal distributions. Fracture transmissivity was estimated from an analytical solution of inflow into the tunnel through an individual fracture and the total measured inflow into the tunnel. 16 fractures were incorporated in the model along the horizontal borehole. The packer test data in the different well intervals were used to estimate the range in fracture transmissivity. A relationship between the fracture transmissivity and fracture radius was developed. The fractures in the tunnel and borehole were used to derive fracture orientation and

    Compelling evidence supporting the benefits of social engagement in older adults has been increasingly discussed. However, knowledge regarding an intergenerational program is limited. Herein, we provide a targeted review of intergenerational programs by focusing on our novel interventional program, Research on Productivity through Intergenerational Sympathy. The Research on Productivity through Intergenerational Sympathy program is an intergenerational picture-book reading program launched in 2004. Participants were involved a 3-month intensive weekly training seminar comprising classes about book selection, reading techniques and basic knowledge of children's school life. Subsequently, they participated in group activities that involved playing a hand game, and reading picture books to children at kindergartens, elementary schools and public childcare centers, once every 1-2 weeks. The Research on Productivity through Intergenerational Sympathy program has shown improvement of physical and psychological functioning of older adults and healthy upbringing of children. Similarly, Experience Corps - designed to train and place volunteers in participating elementary schools for an academic year during which time they assist teachers - also showed positive effects for older adults' health status and the psychological/academic success of young children in the USA. Health promotion efforts for older adults must support social policy for the creation of meaningful service programs for older adults on a large social scale. As such, an intergenerational program based on the concept of social capital, defined as "features of social organization, such as trust, norms and networks, that can improve the efficacy of society by facilitating coordinated actions," is an effective and sustainable program for health promotion among older adults. © 2016 Japan Geriatrics Society.

    The Japan Atomic Energy Research Institute has been proposing the Neutron Science Project (NSP). The NSP requires pulse and CW proton beams with an energy of 1.5 GeV and an average beam power up to 8MW. This paper describes design concepts and parameters of the linac. A front end part of the linac, which consists of RFQ, DTL and SDTL sections, uses normal conducting structures and a high energy part uses superconducting (SC) structures. The linac has two injector lines for the pulse and the CW modes, respectively, and the two lines merge at 7 MeV. The total linac length is approximately 900 m and most of the part (>75%) is the superconducting section. An equipartitioning design, which is a new idea to suppress an emittance growth for high power linacs, has been taken for the DTL, the SDTL and the SC sections. Compared with the conventional constant phase advance design scheme, the equipartitioning design scheme is proved to be a good approach to suppress the longitudinal emittance growth. (author)

    1996-01-01

    There are 48 commercial nuclear power stations in operation in Japan as of January 1, 1995, which supplies about 28% (2.2 x 10 8 MWh) of total annual electricity generation in FY 1992. Accordingly, as the nuclear power contributes so much in electricity generation, there is a growing concern in the public toward the safety on decommissioning nuclear power station. It is gravely important to secure the safety throughout the decommissioning. This paper discusses: the decommissioning situation in Japan; the Japanese national policy for decommissioning of commercial nuclear power stations; R and D for decommissioning of commercial nuclear power stations in Japan; and the present conditions of low-level radioactive wastes disposal in Japan

    All the works of shielding repair and safety general inspection for the nuclear ship ''Mutsu'' were completed. For advancing the research and development of nucear ships, of course, the data and experience of the behavior of marine nuclear reactors are required, which can be obtained only by operating nuclear ships. The Agency will carry out the experimental voyage after the prescribed tests are finished, and endeavor to attain the objective. A new development was observed on the new home port for the Mutsu. In May, 1981, the agreement was reached among those concerned to decide Sekine Beach, Mutsu City, as the candidate site after the survey and coordination, and to construct the home port as early as possible. The Agency carried out the survey required for the location, and reported in March, 1982, that the construction of the home port is technically feasible, and also the concept of the home port and the incidental facilities on land was informed to Aomori Prefecture. Hereafter, the compensation for fishery and the purchase of land will be actively promoted. In order to ease the restriction on the energy supply for shipping industry, the technical basis for the practical use of nuclear ships must be urgently consolidated. In this report, the works performed by the Agency in fiscal 1981 are described. (Kako, I.)

    Joint technological development was conducted with the purpose of increasing operational efficiency of metal mines (refining of lead, copper, etc.) in Kazakhstan. This paper explains the fiscal 1995 results. Ores and tailings were sampled from three mines, with wastewater sampled from drainage ponds of one plant. The characteristics and conditions of coexistence of various minerals were studied mineralogically, determining the grades of valuable minerals, identifying and analyzing ore minerals. A hydrometallurgical processing was applied to a preliminary test for the purpose of enhancing research efficiency by separating and concentrating effective substances in the mineral samples as much as possible. Performed as leaching tests were a mechanical stirring method (for fine particles), column method (for coarse particles), bacterial method, chalcopyrite method (for tailing), etc.. In the stirring method, about 80% of copper was recovered. In the tailing concentration by the Fe{sup 3+} chalcopyrite method, the quantity and temperature of Fe{sup 3+} as an oxidizing agent affected the rate of concentration of copper. The bacteria leaching test using the sample from the drainage pond revealed existence of Thiobacillus ferrooxidus bacteria that was effective for leaching. (NEDO)

    Research and development was carried out at a metal mine in the Republic of Kazakhstan for building a system for recovering minerals from low grade ore and tailings without polluting the environment. For the recovery of metals such as copper from low grade ore and tailings, the chalcopyrite leaching, solvent extraction, and electrolytic extraction methods were applied. In the treatment of waste water, the liquid residue after extraction was subjected to oxidation by bacteria. A high quality electrolytic copper with its purity 99.99% or higher was obtained in a test. In the case of the Zhezkent tailings (containing 0.84% copper), though the estimation result negated economic profits with the profit/loss borderline set at the internal return rate of 10%, possibilities were that it might turn to be profitable dependent on changes in the market price or exchange rate. In the case of the complicated ore containing led, zinc, etc., from Nikolayevska located in the eastern part of Kazakhstan, it was found that the floatation method was not suitable for the ore, that the recovery rate decreased greatly when product quality was retained to be high, and that the quality greatly deteriorated when the recovery rate was raised.

    Clinical education is an extremely important process in cultivating healthcare professionals, and the quality of educators has a major impact on the quality of future practitioners. Although practicing clinical midwives contribute to the education of pre-registered midwives and those qualified within the past year (new midwives), the factors defining the educational competencies of clinical midwives have not been clarified. The purpose of this study was to explore the factors that define the mentoring competencies of clinical midwives involved in educating new midwives. An exploratory quantitative research study. Questionnaires were distributed to 694 midwives who had previously conducted educational activities with new midwives at the 63 facilities whose administrator or nurse manager in charge of all staff, including midwives, consented to participate. Of the 694 midwives, 464 (66.9%) returned the questionnaire and 451 (65.1%) valid responses were analyzed. Exploratory factor analyses were performed on the following three concepts: [competency as a professional], [competency as an educator], and [personal characteristics]. [Competency as a professional] consisted of two factors: and ; [competency as an educator] consisted of four factors: , , and ; and [personal characteristics consisted of three factors: exercising leadership> , and . These three concepts were defined by a total of nine sub-concepts (factors), and 41 items were extracted with a reliability coefficient (Cronbach's α) of 0.944 CONCLUSIONS: "Mentoring competencies of clinical midwives (MCCM)" are defined by three concepts and nine sub-concepts, which can be evaluated by 41 items regarding the behavior, thoughts, and characteristics that clinical midwives exhibit when they educate new midwives in clinical settings.

    At Tokai Research Establishment, JAERI, over one thousand people work in hot areas such as reactors, accelerators, chemical laboratories and waste treatment plants. The monitoring for internal contamination of this personnel is presented. Routine and special monitoring are carried out. The object of the former is to check for the presence of significant contamination, and that of the latter is to estimate body burden and committed dose equivalent, if necessary. Heavy shield and shadow shield whole body counters, a low energy lung counter and a wound monitor are used to detect the internal contamination due to γ or chi ray emitters, and bioassay technique is used for α or β emitters and uranium. The results of the monitoring until now are presented. (H.K.)

    Results are presented of internal contamination surveys carried out since 1969 at Tokai Research Establishment. Routine monitoring sometimes revealed significant internal contamination for tritium workers, but almost never for others. The number of subjects for special monitoring varied according to the activities. In 1965, the number of subjects for special monitoring was nearly 300, due to a reactor repair that year. In recent years, the number or special monitoring has been several tens or so. With regard to special monitoring, the workers with significant internal contamination were less than 50%. The internal dose (50 years) estimated for the majority of subjects was of mrem order. During the past 15 years, only several cases of exposure of rem order were found. The highest dose experienced was about 4 rems ( 131 I thyroid) (U.K.)

  3. Industrial lasers in Japan

    1991-03-01

    I am to report on some aspects of industrial lasers in Japan. Mostly centering on the market. In Japan, the history of laser developnent is rather profound. And long. Ever since the first invention of the laser in this country in 1960. This is partly because of the fact that in Japan the spectroscopic studies of the ruby was very popular in the late 1950's. Ever since niost of the work has been done in the research laboratories of the industry, not in the universities or not in the governmental laboratories. And since that time our first activity was mainly centering on the basic research, but after that time we have the evolution of the technology. One of the features in Japan is that the activity of developement and research of laser technology from the very basic phase up to the present commercialization has been done by the same group of people, including ine. We had a national project which ended about six years ago which was sponsored by MITI. MITI is Ministry of International Trade and Industry in Japan. And because of this national project, the effect of this project had a very enlightening effect in Japan. And after that our Japanese laser market became very flourishing.

    Disasters involving radiation exposure are particularly pernicious and have long-lasting psychological consequences. This paper reviews evidence regarding the specific consequences after the Three Mile Island and Chernobyl nuclear power plant accidents and shows the important association of risk perceptions with poor subjective health and emotional distress. The two groups used to illustrate the findings about the mental health aftermath are mothers of young children and clean-up workers. The importance of unbiased epidemiologic data for designing appropriate and needed mental health services and of integrating these services within a general medical framework are also discussed. Specific recommendations for enhancing the quality and hence utility of epidemiologic research are provided, which include consensus building with the affected community and full partnership in all steps in the design and execution of the research; if a random sample is the intended target, allowing unselected residents to participate if they wish; providing incentives to participation, including giving results of blood tests, thyroid tests, and physical examinations in a timely manner and training interview staff in motivational interviewing techniques; communicating the professional, scientific nature of the research and the consenting process, as well as the partnership with the community; and directly sharing the findings together with local partners to the respondents and interviewers prior to publishing the results elsewhere and allowing a time and place for feedback from the community. Given that mental health may be the largest public health problem unleashed by Fukushima, as was the case after Three Mile Island and Chernobyl, and knowing that poor mental health is a leading cause of disability, physical morbidity, and mortality, it is important that comprehensive health monitoring involve clinically sensitive measures of emotional well-being, particularly with regard to depression

    2002-08-01

    Japan Atomic Energy Research Institute (JAERI), as a core organization devoted to comprehensive nuclear energy research, has steadily promoted nuclear energy research aiming at long-term and stable supply of energy supporting the basis of national existence, advanced nuclear science and engineering leading to increase in Japanese industrial competitive power, etc. Through these undertaking, JAERI has produced a lot of remarkable achievements to contribute the national requests mentioned above. In total, about 1.8 trillion-yen of national funds and over 60,000 person · years of researchers and technical staffs have been invested in the R and D's for the past 45 years. Recently it has been argued and recognized to evaluate how the profits of R and D results in public research institutes supported by national funds are returned to the Japanese people as taxpayers and society as part of an administrative and financial reform. Then, seeing its 45th anniversary, JAERI has tried to evaluate the effects of the R and D achievements on the Japanese society and economy apart from the reviews on the management of the organization and research results by the ex-house experts from the viewpoints of specialty and technical aspects. In order to execute the aforementioned evaluation, JAERI established the in-house Ad hoc Committee for Evaluation of R and D Achievements where decision of the evaluation plan is made, in July 2001, and executed the evaluation followed by assembling the necessary database collected from individual branches. Results obtained from these activities were finally summarized in the Ad hoc Committee. Because a methodology for quantitative evaluation of the economical effects, i.e. cost-benefit effects of R and D's was not established yet, the evaluation was prudently carried out with the assistance of three think tanks and under advices by three ex-house experts. R and D's in JAERI are not limited to the ones where benefits corresponding to profits can be

    This paper analyzes the distribution of the Subsidiary Fund for Scientific Research, a predecessor to the Grant-in-Aid for Scientific Research (KAKENHI), which operated in Japan from the 1930s to 1950s. It reveals that the Japanese government maintained this wide-ranging promotion system since its establishment during the war until well into the postwar period. Previous studies insist that, at the end of the war, the Japanese government generally only funded the research that it considered immediately and practically useful. In contrast to this general perception, my analysis illustrates that both before and after the war, funding was allotted to four research areas: natural science, engineering, agriculture, and medicine. In order to illuminate this continuity, I compare the Subsidiary Fund with another research fund existing from 1933 to 1947: the Grant of the Japan Society for the Promotion of Science (JSPS). The comparison demonstrates that the JSPS received externally raised capital from the military and munitions companies. However, while this group focused upon engineering and military-related research as the war dragged on, the Subsidiary Fund has consistently entrusted scientists with the authority to decide the allocation of financial support.

    The research aims to construct a recyclable resources distribution network in coordination with other Japan Sea countries so as to establish measures for the effective utilization of resources originating in Japan. The research covers the needs in China and in Russia's Far East provinces for used electrical home appliances and the supply capability of Japan's four prefectures on Japan Sea including Akita Prefecture. Demand in the countries on the other side of the sea for three major categories of electrical home appliances (color television sets, washing machines, and refrigerators) for 2010 and 2025 is predicted. Part of the predicted demand is specified to be for used items, and a scenario is built based on the reuse substitution rate. On the other hand, in view of the life time of such commodities and the rate of reusables in the amount of waste generated, a conclusion is reached that probabilities are that all such appliances from the four Japanese prefectures will be put to reuse. When the reuse rate is estimated at 10% for goods under the three major categories from the four prefectures, approximately 20,000 articles out of each of the three categories will be put to reuse, and this will lead to a reduction of CO2 emissions of 7700 tons a year.

    2003-11-01

    The Japan Atomic Energy Research Institute (JAERI), as a core organization devoted to comprehensive nuclear energy research, has steadily promoted various types of research and development (R and D) studies since its establishment in June 1956. Research activities are aimed at performing (1) R and D for nuclear energy, (2) the utilization and application of radiation-based technologies, and (3) the establishment of basic and fundamental research in the nuclear field. Last year, the socio-economic effects on items (1) and (2) were qualitatively and quantitatively evaluated. The quantitative evaluation of item (3) from the viewpoint of a socio-economic effect, however, calls for a different concept and methodology than previously used cost-benefit approach. Achievements obtained from the activities conducted over the last 10 years implied that socio-economics in basic research funded by the public could contribute to the (1) increase in useful intellectual stocks, (2) upbringing of highly skilled college graduates, (3) construction of new scientific facilities and creation of methodologies, (4) stimulation and promotion of social interrelations by networking, (5) increase of one's ability to solve scientific problems, and (6) establishment of venture companies. In this study, we focused on item (4) for the analysis because it assumed that the external economic effect has a link with the socio-economic effects accompanying the networking formation. For the criteria of socio-economic effects we assume that the external effect becomes significant in proportion to the width of networking and/or the magnitude of cooperation measured by numbers of co-writing studies between JAERI and the research bodies, namely private and governmental sectors and universities. Taking these criteria into consideration, the subsequent four items are prepared for quantitative study. They are (1) to clarify the basic research fields where JAERI has been established a significant effort to

    This study has two purposes. The first purpose is to extract statistics from a database of jobposting cards, previously little-used as a data source, to assess the academic job market. The second purpose is to connect statistics on the academic job market with monitoring of indicators of policy progress related to the mobility and instability of research personnel. The data source used in this study is a job-posting database named JREC-IN Portal, which is the de facto standard for academic job seeking in Japan. The present results show a growing proportion of fixed-term researchers in the Japanese academic job market and that job information is increasingly diverse. (Author)

    Several recent improved methods for the EGFM are introduced in order to avoid artificial holes seen in the synthetic acceleration spectrum. Furthermore evaluation of input ground motions at Wolsung NPP are performed by varying the source parameters that may control the high-frequency wave radiation and the deviation of the synthetic motions are revealed. The PSHA case studies for four NPP sites (Wolsung, Kori, Uljin, Younggwang) are performed. In the analysis, site-specific attenuation equations developed for Korean NPP sites are employed, and the seismic hazards for the target sites are evaluated in the case where the four kind of seismic source models are considered. Moreover, the PSHA for Wolsung and Younggwang are conducted by using the site-specific attenuation equation with the index of response spectra and the uniform hazard spectra are evaluated for the two sites. The supporting tool for seismic response analysis and the evaluation tool for evaluating annual probability of failure were integrated in the frame of the seismic risk assessment system. Then, the tools were applied to the seismic risk assessment of the conventional EDG and isolated EDG. General information such as earthquake parameters and regional distribution of seismic intensity is summarized on the 2005 West Off Fukuoka earthquake. Then, the observed strong motion records in Japan and Korea sites are compiled, and regional distribution of peak accelerations are represented. Moreover, the peak accelerations of the records are compared with the values estimated from the existing attenuation equations.

    In the safety assessment of geological disposal for high level radioactive wastes, it is important to develop the modelling for evaluating mechanical effects of crustal movements on the disposal system in Japan. In this study, the model on crustal movements is represented by accumulating two components of velocity magnitude of the crust to horizontal direction, caused by transient movements associated with fault and/or volcanic activities and ordinary movements with the other continuous factors. We have quantified the ordinary movements with the statistical analysis of data included in the GEONET (GPS Earth Observation Network System) of GSI (Geographical Survey Institute). Okada Model is applied for evaluating the transient movements, which can handle three-dimensional movements of earthquake and volcanic activities theologically and comprehensively. In this report, we provide the specification of the model on crustal movement and analyze the horizontal velocity in Tohoku region using the model. The result indicates that the ordinary movements are classified with magnitude of the longitudinal velocities. The cluster of longitudinal velocities has been distributed along the plate boundary. Because the velocities of the ordinary movements are grater than one of transient movements, the spatial distribution of longitudinal velocities in Tohoku region is similar to that of the ordinary movements.

    Research was made on joint implementation (JI) for preventing global climate changes in China. Since such the stove and furnace consume a large amount of energy, their improvement and energy saving are important for integrated iron plants. Maanshan iron plant was selected for the research. All the furnaces were manually operated without combustion control systems, and oxygen meters for exhaust gas frequently troubled. As measures for the stoves, operation at a proper air fuel ratio, improvement of over heat storage combustion, and dust cleaning for waste heat recovery gas heaters were proposed. For the furnaces, a proper oxygen content at the end of furnaces (reduction of invasion air) was proposed to improve exhaust gas loss up to that in Japan. For this target, reinforced instrument management and standardized combustion control are essential. JI of software improvement for operation and management can reduce annual greenhouse effect gas emission to 45,900t and 6,300t in carbon equivalent for the stove and furnace, respectively. CO2 reduction is also estimated to be 1,173,000t and 205,000t in China of 107,570,000t in raw steel production, respectively. 28 figs., 32 tabs.

    As evidenced by high-throughput sequencers, genomic technologies have recently undergone radical advances. These technologies enable comprehensive sequencing of personal genomes considerably more efficiently and less expensively than heretofore. These developments present a challenge to the conventional framework of biomedical ethics; under these changing circumstances, each research project has to develop a pragmatic research policy. Based on the experience with a new large-scale project-the Genome Science Project-this article presents a novel approach to conducting a specific policy for personal genome research in the Japanese context. In creating an original informed-consent form template for the project, we present a two-tiered process: making the draft of the template following an analysis of national and international policies; refining the draft template in conjunction with genome project researchers for practical application. Through practical use of the template, we have gained valuable experience in addressing challenges in the ethical review process, such as the importance of sharing details of the latest developments in genomics with members of research ethics committees. We discuss certain limitations of the conventional concept of informed consent and its governance system and suggest the potential of an alternative process using information technology.

    This study investigated the circumstances and problems that departments of forensic medicine encounter with bereaved families regarding samples obtained from medico-legal autopsies. A questionnaire was posted to all 76 departments of forensic medicine performing medico-legal autopsies in Japan, and responses were received from 48 (63.2%). Of the respondents, 12.8% had approached and communicated with bereaved families about collecting samples from the deceased person during an autopsy and the storage of the samples. In addition, 23.4% of these had informed families that samples might be used in research. Eighteen departments had received enquiries and requests from families about the samples, with most requests concerning their return. The response to such requests varied according to the department. Few departments interacted with the bereaved families regarding the procedure for obtaining autopsy samples, and their methods for handling family concerns differed depending on the person within the department authorised to contact the family. Moreover, the procedures for engaging in such communication have long been unclear, and no legal or ethical consensus or agreement with the general public has been established. It is important for researchers to further discuss the correct way for forensic medicine departments to communicate with bereaved families. Published by the BMJ Publishing Group Limited.

    This article examines competition in Japan and its link to postwar economic prosperity. While Japan's industrial structure and competition policy seem to indicate that competition in Japan has been less intense, the empirical evidence does not support this conclusion. The sectors in which competition was restricted prove to be those where Japan was not internationally successful. In the internationally successful sectors, internal competition in Japan was invariably fierce. While the level of...

    IHI has designed and constructed the CCTF at JAERI to be used in the safety analysis research on the loss of coolant accident in a PWR plant. This test facility is planned so that reflood phenomenon in the PWR plant (a phenomenon is that the bared and overheated core is reflooded by the emergency core cooling system when the coolant loss accident occurred) is simulated under various test conditions. The CCTF is the largest-scale test plant in the world, composed of approximately 2000 simulated fuel rods (electric heaters), 1 simulated pressure vessel, 4 primary cooling loops, 2 simulated steam generators, emergency core cooling system, and so on. The test conditions are controlled, and the test steps are sequentially progressed by the computing system, and test data are collected by the data acquisition system. Furthermore, IHI is now designing and constructing the SCTF in accordance with the JAERI research plan. The SCTF is similar to the CCTF in scale. Main feature of the SCTF is the form of the simulated core and the simulated pressure vessel, which is of slab construction to be representative of the radial section of the PWR reactor. Reliable and various data for safety analysis are expected by the CCTF and the SCTF. (author)

    Four researchers were invited from EU countries to promote R & D of petroleum substituting energy in Japan, and the joint research was made in institutes of Agency of Industrial Science and Technology related to each theme for 50 days. On the research on deep geothermal prospecting based on volcanic halocarbon group, it was showed that halocarbon discharged from volcanic or hydrothermal system is an important window to survey activities within the earth. On the research on catalyst for hydrogenation of coal-derived liquid, XPS data was reported, and some preliminary conclusions were obtained. On the research on oxide system anode material for Li secondary cells, a method for improving the state of host to ion moving in 1-D to 3-D networks by diffraction method was showed. In particular, the method was effective to offer electronically sensitive environment to moving ion system. On the research on hydro-dechlorination of hydrocarbon halide, the theme related to environmental measures against waste hydrocarbon halide (depletion of the ozone layer) was studied. 83 refs., 32 figs., 20 tabs.

    Full Text Available The 3-GeV rapid cycling synchrotron (RCS of the Japan Proton Accelerator Research Complex was commissioned in October 2007. Via the initial beam tuning and a series of underlying beam studies with low-intensity beams, since December 2009, we have intermittently been performing beam tuning experiments with higher-intensity beams including the injection painting technique. By optimizing the injection painting parameters, we have successfully achieved a 420 kW-equivalent output intensity at a low-level intensity loss of less than 1%. Also the corresponding numerical simulation well reproduced the observed painting parameter dependence on the beam loss, and captured a characteristic behavior of the high-intensity beam in the injection painting process. In this paper, we present the experimental results obtained in the course of the RCS beam power ramp-up, especially on the beam loss reduction achieved by employing the injection painting, together with the numerical simulation results.

  10. State of opening the cover and carrying out the checkup of the reactor vessel of the nuclear-powered ship 'Mutsu' by Japan Atomic Energy Research Institute

    In the checkup by opening the cover of the reactor vessel of the nuclear-powered ship 'Mutsu', Japan Atomic Energy Research Institute carried out the checkup and maintenance for the reactor proper, control system and primary coolant facilities including the secondary side of steam generators and the pressure balancing valve of the containment vessel. The works were classified into the opening of the reactor, checkup, maintenance and restoration. The opening was begun on August 4, 1988, and finished on December 5. The checkup and maintenance were begun on September 22, and are still continued now. The maximum radiation dose rate on the surfaces of fuel assemblies and control rods and at the positions 1 m distant from them was measured. The results of the checkup of various components are reported. In 290 absorbent rods of control rods, spot corrosion and discoloration were observed, of which the spot corrosion penetrated the walls of 4 rods. Also in 12 fuel rods, spot corrosion was observed near the welded end plugs, but leak was not observed. (K.I.)

    Full Text Available A prototype cavity for the annular-ring coupled structure (ACS for use in the Japan Proton Accelerator Research Complex (J-PARC linac has been developed to confirm the feasibility of achieving the required performance. This prototype cavity is a buncher module, which includes ten accelerating cells in total. The ACS cavity is formed by the silver brazing of ACS half-cell pieces stacked in a vacuum furnace. The accelerating cell of the ACS is surrounded by a coupling cell. We, therefore, tuned the frequencies of the accelerating and coupling cells by an ultraprecision lathe before brazing, taking into account the frequency shift due to brazing. The prototype buncher module was successfully conditioned up to 600 kW, which corresponds to an accelerating field that is higher than the designed field of 4.1  MV/m by 30%. We describe the frequency-tuning results for the prototype buncher module and its high-power conditioning.

    The overall aim of the Co-operative Program has been to promote the exchange of information on technology for the management of High-Level Wastes (HLW) and to encourage research and development relevant to such technology. During the 13 years that the Program has been carried out, HLW management strategies have matured and developed internationally, and Japan has commenced construction of a domestic reprocessing and vitrification facility for HLW. The HLW management strategy preferred is a national decision. Many countries are using vitrification, direct disposal of spent fuel or a combination of both to handle their existing wastes whereas others have deferred the decision. The work carried out in the Co-operative Program provides strong scientific evidence that the durability of ceramic waste forms is not significantly affected by radiation damage and that high loadings of actinide elements can be incorporated into specially designed ceramic waste forms. Moreover, natural minerals have been shown to remain as closed systems for U and Th for up to 2.5 b y. All of these results give confidence in the ability of second generation waste forms, such as Synroc, to handle future waste arisings that may not be suitable for vitrification 87 refs., 15 tabs., 22 figs.

Recently, the design painting injection study has been commenced with the aim of high output beam power at the extraction. In order to observe the phase space footprint of the painting injection, a method was developed utilizing a beam position monitor (BPM in the so-called single pass mode. The turn-by-turn phase space coordinates of the circulating beam directly measured using a pair of BPMs entirely positioned in drift space, and the calculated transfer matrices from the injection point to the pair of BPMs with several successive turns were used together in order to obtain the phase space footprint of the painting injection. There are two such pairs of BPMs placed in two different locations in the RCS, the results from which both agreed and were quite consistent with what was expected.

    Japan Atomic Energy Agency is now conducting the Mizunami Underground Research Laboratory (MIU) project. The MIU consists of two shafts (main shaft: 6.5m, ventilation shaft: 4.5m diameter) and horizontal research galleries, in sedimentary and granitic rocks at Mizunami City, Central Japan. The MIU project is a broad scientific study of the deep geological environment providing the basis for research and development for geological disposal of high level radioactive waste. One of the main goals is to establish techniques for investigation, analysis and assessment of the deep geological environment in fractured crystalline rock. As a part of the MIU project, we carried out the Reverse-Vertical Seismic Profile (R-VSP) using vibrations from the blasting for the shaft excavations and drilling of boreholes in the horizontal research galleries and examined the applicability of this method to imaging of geological structures around underground facilities, such as the unconformity between the sedimentary rocks and the basal granite, and faults and fracture zones in the granite. R-VSP method is a seismic method utilizing the receiver arrays on surface and seismic sources underground (e.g. in boreholes). This method is advantageous in that planning of 3-dimensional surveys is easy compared with reflection seismic surveying and conventional VSP because seismic source arrays that are major constraint for conducting surveys on surface are unnecessary. The receiver arrays consist of six radial lines on surface with a central focus on the main shaft. Seven blast rounds for the main shaft excavation from GL-52.8m to GL-250m and the borehole drilling in the GL-200m horizontal research gallery were observed. Three types of data processing, conventional VSP data processing (VSP-CDP transform and VSP migration), Reflection data processing utilizing Seismic interferometry method (“Seismic interferometry”) and Reflection mapping utilizing Image Point transform method (“IP transform

    This paper summarizes research activities in National Institute of Radiological Sciences (NIRS) for evaluation of the radiation effects on selected terrestrial and aquatic organisms as well as the ecosystems. Seven organisms, conifers, fungi, earthworms, springtails, algae, daphnia and Medaka are presently selected to study. Most of them play important roles in Japanese ecosystems and are possibly useful for bio-indicator of the radiation effects. For the estimation of possible radiation dose, transfers of radionuclides and related elements from medium to organisms are evaluated. Dose-effect relationships of acute gamma radiation on the survival, growth, and reproduction of selected organisms have been studied. Studies on the effect of chronic gamma radiation at low dose rate were also started. In order to understand the mechanism of radiation effects and to find possible indicators of the effects, information of genome- and metagenome-wide gene expression obtained by the High Coverage Expression Profiling (HiCEP) has been collected. Evaluation of ecological effects of radiation is more challenging task. Study methods by using three-species microcosm were established, and an index for the holistic evaluation of effects on various ecological parameters was proposed. The microcosm has been simulated for its population dynamics, and mass and energy budgets as a computer simulation code. Developments of more complicated and practical model ecosystems have been started. The Denaturant Gradient Gel Electrophoresis (DGGE) has been applied on soil bacterial community in order to evaluate the radiation effects on soil ecosystems. (author)

    A cross-sectional observational study to determine the response distribution, internal consistency, and construct, concurrent, and discriminative validities of The Scoliosis Research Society-22 (SRS-22) Patient Questionnaire translated into Japanese as compared with the other language versions. To validate the Japanese version of SRS22. The SRS-22 was translated into several languages but yet not into Japanese. The Japanese SRS-22 and Medical Outcomes Study Short Form 36 were simultaneously administered to 114 adolescent idiopathic scoliosis patients. Exploratory factor analysis revealed a 4-factor structure, though several items were not loaded as theoretically expected. The originally constructed Japanese SRS-22 subscales and the English version showed similar response distribution. Internal consistency was fair but lower than that of the English version. The concurrent validity of the translated version, except for the self-image subscale, was supported using Medical Outcomes Study Short Form 36 subscales as a reference. The function scale differed significantly by curve angle magnitude and treatment status. The self-image score was the highest in patients under observation when curve angle was or = 40 degrees, respectively. The Japanese SRS-22 is valid and may be useful for clinical evaluation of Japanese scoliosis patients, though the self-image subscale may need further assessment.

    Through the last 7-8 years of collaboration with the SKS hypernuclear physics group at KEK, we have concentrated on the measurement of Λ hypernuclear decays. Non-mesonic weak decay mode of Λ hypernucleus is especially interesting and has been the central theme of our collaboration researches. We have measured the weak decay observables of Λ hypernuclei over a broad mass range, A = 11 - 89, from which their characteristic mass dependences are clearly observed. The lifetime decreases slightly from that of free Λ and quickly saturates at ∼80 percent of τ Λ in free space as the mass number increases. The preliminary results on Γ n /Γ p confirm the domination of the ratio Γ n over Γ p and restate the existing discrepancy between the values of experimental data and theoretical calculation. Much improved neutron detection efficiency in the experiment, KEK-PS E369, will shed light on the understanding of this puzzling ratio. The collaboration produced a series of excellent data on the decay. (author)

    The basic research on food irradiation in Japan was begun around 1955 by universities and national laboratories. In 1967, food irradiation was designated to the specific general research on atomic energy, and the national project on large scale was continued until 1983. As the result, the treatment of germination prevention for potatoes was approved by the Ministry of Health and Welfare in 1972. The Co-60 gamma ray irradiation facility of Shihoro Agricultural Cooperative is famous as the facility that succeeded in the practical use of food irradiation for the first time in the world. But the practical use of food irradiation stagnates and the research activities were reduced in Japan due to the circumstances thereafter. The effect of radiation to foods and living things is explained. The features of the radiation treatment of foods are small temperature rise, large transmissivity, no residue, the small loss of nutrition and large quantity, continuous treatment. The safety of irradiated foods is explained. The subjects for hereafter are discussed. (K.I.)

    In 1967 the National Institute of Radiological Sciences in Chiba estimated the radiation doses in air from the atomic bombing of Hiroshima and Nagasaki by using some building materials exposed to the nuclear explosions in both cities. These estimated doses were in good agreement with the doses estimated on the basis of the Ichiban project by the research group at Oak Ridge National Laboratory which were the basis for the Atomic Bomb Casualty Commission's tentative 1965 radiation dose (T65D). Recently the radiation doses in Hiroshima and Nagasaki have been reevaluated by Lawrence Livermore National Laboratory and Oak Ridge National Laboratory. In Japan a new research group was started last August, with the intention of making new estimates of doses from the atomic bombs in cooperation with US research groups

    We conducted a 17-year nationwide survey (1999-2015) to elucidate the clinical outcomes of patients with primary myelofibrosis (PMF) in Japan. Questionnaires were sent annually to approximately 500 hematology departments. Newly diagnosed patients with PMF were enrolled in this study, and were followed up annually to collect prognostic information. Approximately 50 patients were enrolled per year, yielding a total of 780 patients with PMF included in this study. The median age at diagnosis was 66 years. At the time of analysis, the median survival duration was 47 months, and the 3-year overall survival rate was 59 %. Infection and disease transformation into acute leukemia were the most frequent causes of death. Of the proposed prognostic models for predicting the outcomes of PMF patients in Japan, the Dynamic International Prognostic Scoring System of PMF plus model was the most feasible. Forty-three patients received allogeneic hematopoietic stem cell transplantation (alloSCT) at a median of 343 days after diagnosis. This treatment significantly prolonged the survival of PMF patients, and the 3-year overall survival rate after first alloSCT was 84 %. A long-term registration study is required for further evaluation of prognosis and the impact of treatments on survival.

    Research into applied aspects of biological hydrogen production is carried out on a much lower level in Europe than basic hydrogenase research. However, the screening for good H{sub 2} producers, their cultivation, and the development of optimised culture and bioreactor systems has never been a strength in Europe. Although there are a few good groups in Europe major contributions in this field traditionally come from countries outside Europe. However, in the nineties a special application-oriented research subfield has begun to evolve in Europe: the use of genetic enginering to rationally optimise H{sub 2} producing organisms. The most important players who focus on green algae, cyanobacteria, and purple bacteria can be found in Germany, France, and Sweden. In European biohydrogen research, a large and diverse variety of organisms is investigated. Among the organisms most thoroughly studied are Alcaligenes eutrophus, Escherichia coli, Rhodobacter capsulatus, sulfate-reducing bacteria, and methanogenic bacteria. Moreover, a leading position has been obtained with respect to molecular genetics of green algae and cyanobacteria, albeit on a low level. The fact that such a broad range of diverse organisms is studied has advantages and disadvantages. A positive aspect is that the multitude of different approaches had led to several unexpected results which had otherwise been overlooked. On the other hand, an obvious link to biohydrogen production is often lacking. Moreover, there are many 'me-too' approaches and results in which previous findings are only reproduced for another organism as well. (orig.)

    To assess the attitudes of the Japanese general public towards pharmacogenomics research and a DNA bank for identifying genomic markers associated with ADRs and their willingness to donate DNA samples, we conducted a national survey for 1,103 Japanese adults from the general public, not a patient population. The response rate was 36.8%. The majority of the respondents showed a positive attitude towards pharmacogenomics research (81.0%) and a DNA bank (70.4%). Considering fictitious clinical situations such as taking medications and experiencing ADRs, the willingness to donate DNA samples when experiencing ADRs (61.7%) was higher than when taking medications (45.3%). Older generations were significantly associated with a decreased willingness to donate (OR = 0.45, CI 0.28-0.72 in 50s. OR = 0.49, CI: 0.31-0.77 in 60s). Positive attitudes towards pharmacogenomics research, a DNA bank, blood/bone marrow/organ donation were significantly associated with an increased willingness. However, the respondents had the following concerns regarding a DNA bank: the confidentiality of their personal information, the manner by which research results were utilized and simply the use of their own DNA for research. In order to attain public understanding to overcome these concerns, a process of public awareness should be put into place to emphasize the beneficial aspects of identifying genomic markers associated with ADRs and to address these concerns raised in our study. Further study is needed to assess the willingness of actual patients taking medications in real situations, since the respondents in our study were from the general public, not a patient population, and their willingness was assessed on the condition of assuming that they were patients taking medications.

    Two-year, prospective cohort data collected for the Japan epidemiological research of Occupation-related Back pain study were used for the analysis. To identify potential risk factors for the development of new-onset sciatica in initially symptom-free Japanese workers with no history of sciatica. Although the associations between individual and occupational factors and cases of new-onset sciatica are established, the effect of psychosocial factors on the development of sciatica has still not been adequately clarified. In total, 5310 participants responded to a self-administered baseline questionnaire (response rate: 86.5%). Furthermore, 3194 (60.2%) completed both 1- and 2-year follow-up questionnaires. The baseline questionnaire assessed individual characteristics, ergonomic work demands, and work-related psychosocial factors. The outcome of interest was new-onset sciatica with or without low back pain during the 2-year follow-up period. Incidence was calculated for participants who reported no low back pain in the preceding year and no history of lumbar radicular pain (sciatica) at baseline. Logistical regression assessed risk factors associated with new-onset sciatica. Of 765 eligible participants, 141 (18.4%) reported a new episode of sciatica during the 2-year follow-up. In crude analysis, significant associations were found between new-onset sciatica and age and obesity. In adjusted analysis, significant associations were found for obesity and mental workload in a qualitative aspect after controlling for age and sex. Consequently, in multivariate analysis with all the potential risk factors, age and obesity remained statistically significant (odds ratios: 1.59, 95% confidence interval: 1.01-2.52; odds ratios: 1.77, 95% confidence interval: 1.17-2.68, respectively). In previously asymptomatic Japanese workers, the risk of developing new-onset sciatica is mediated by individual factors. Our findings suggest that the management of obesity may prevent new

    We compiled the results of the source analysis obtained under the collaboration research. Recent construction scheme for source modeling adopted in Japan is described, and strong-motion prediction is performed assuming the scenario earthquakes occurring in the Ulsan fault system, Korea. Finally Qs values beneath the Korean inland crust are estimated using strong-motion records in Korea from the 2005 Off West Fukuoka earthquake (M7.0). Probabilistic seismic hazard for four NPP sites in Korea are evaluated, in which the site specific attenuation equations with Index SA developed for NPP sites are adopted. Furthermore, the uniform hazard spectra for the four NPP sites in Korea are obtained by conducting the PSHA by using the attenuation equations with the index of response spectra and seismic source model cases with maximum weights. The supporting tools for seismic response analysis, the evaluation tool for evaluating annual probability of failure, and system analysis program were developed for the collaboration. The tools were verified with theoretical results, the results written in the reference document of EQESRA, and so forth. The system analysis program was applied for the investigation of the effect of improving the seismic capacity of equipment. We evaluated the annual probability of failure of isolated and non-isolated EDG at Younggwang NPP site as the results of the collaboration. The input ground motion for generating the seismic fragility curve was determined based on the seismic hazard analysis. It was found that the annual probability of failure of isolated EDG is lower than that of non-isolated EDG.

    The transverse impedance of eight extraction pulsed kicker magnets is a strong beam instability source in the 3-GeV rapid cycling synchrotron (RCS) at the Japan Proton Accelerator Research Complex. Significant beam instability occurs even at half of the designed 1 MW beam power when the chromaticity (ξ ) is fully corrected for the entire acceleration cycle by using ac sextupole (SX) fields. However, if ξ is fully corrected only at the injection energy by using dc SX fields, the beam is stable. In order to study realistic beam instability scenarios, including the effect of space charge and to determine practical measures to accomplish 1 MW beam power, we enhance the orbit particle tracking code to incorporate all realistic time-dependent machine parameters, including the time dependence of the impedance itself. The beam stability properties beyond 0.5 MW beam power are found to be very sensitive to a number of parameters in both simulations and measurements. In order to stabilize a beam at 1 MW beam power, two practical measures based on detailed and systematic simulation studies are determined, namely, (i) proper manipulation of the betatron tunes during acceleration and (ii) reduction of the dc SX field to reduce the ξ correction even at injection. The simulation results are well reproduced by measurements, and, as a consequence, an acceleration to 1 MW beam power is successfully demonstrated. In this paper, details of the orbit simulation and the corresponding experimental results up to 1 MW of beam power are presented. To further increase the RCS beam power, beam stability issues and possible measures beyond 1 MW beam power are also considered.

    To assess the attitude of Japanese patients towards pharmacogenomics research and a DNA bank for identifying genomic markers associated with adverse drug reactions (ADRs) and their willingness to donate DNA samples, we conducted a survey of 550 male and female patients. The majority of the respondents showed a positive attitude towards pharmacogenomics research (87.6%) and a DNA bank (75.1%). The willingness to donate DNA samples when experiencing severe ADRs (55.8%) was higher than when taking medications (40.4%). Positive attitudes towards a DNA bank and organ donation were significantly associated with an increased willingness to donate. Though the level of positive attitude in the patient population was higher than that in the general public in our former study (81.0 and 70.4%, respectively), the level of the willingness of patients to donate was 40.4% when taking medications and 55.8% when experiencing severe ADRs which was lower than that of the general public in our former study (45.3 and 61.7%). The results suggested that the level of true willingness in the patient population was lower than that of the general public considering the fictitious situation presented to the public (to suppose that they were patients receiving medication). It is important to assess the willingness of patients who are true potential donors, not the general public.

  13. Organic photovoltaic energy in Japan

    2007-01-01

    Japan finances research programs on photovoltaic conversion since 1974. Research in this domain is one of the 11 priorities of NEDO, the agency of means of the ministry of economy, trade and industry of Japan. The search for an abatement of production costs and of an increase of cells efficiency is mentioned in NEDO's programs as soon as the beginning of the 1990's. A road map has been defined which foresees photovoltaic energy production costs equivalent to the ones of thermal conversion by 2030, i.e. 7 yen/kWh (4.4 cents of euro/kWh). The use of new materials in dye-sensitized solar cells (DSSC) or organic solar cells, and of new structures (multi-junctions) is explored to reach this objective. The organic photovoltaic technology is more particularly considered for small generation units in mobile or domestic technologies. Japan is particularly in advance in the improvement of DSSC cells efficiency, in particular in the domain of the research on solid electrolytes. Europe seems more in advance in the domain of the new generation of organic solar cells. Therefore, a complementarity may be found between Japan and French teams in the domain of organic solar cells improvement through collaboration programs. (J.S.)

Operations are slated to start in the 2030's. NUMO will select the site through the following three-step process. 1- Selection of preliminary investigation areas by documentary studies; 2- Selection of areas for detailed investigation by borehole programs, etc.; 3- Selection of the site for repository construction by test programs in underground exploration facilities. NUMO is recruiting voluntary candidates for documentary studies. Some municipalities have interested in the project, however, they have not let NUMO to do documentary studies. The mayor of the town of Toyo in Kochi prefecture applied for a documentary study in January 2007. It was the first application in Japan, and NUMO was authorized to implement a documentary study there by the national government in March 2007. But NUMO withdrew its application in April 2007 because of opposition from prefecture governors, stakeholders and general public in the town. To improve this situation, the government strengthened its efforts to start documentary studies. For example, they changed the rule so that the government could propose some suitable towns as candidates for documentary studies, in addition to accepting voluntary applications.

    The progress of large scale scientific simulation environment in JAERI is briefly described. The expansion of fusion simulation science has been played a key role in the increasing performances of super computers and computer network system in JAERI. Both scalar parallel and vector parallel computer systems are now working at the Naka and Tokai sites respectively, and particle and fluid simulation codes developed under the fusion simulation project, NEXT, are running on each system. The storage grid system has been also successfully developed for effective visualization analysis by remote users. Fusion research is going to enter the new phase of ITER, and the need for the super computer system with higher performance are increasing more than as ever along with the development of reliable simulation models.

    Since 1967 research activities on food irradiation in Japan have been carried out under the National Food Irradiation Programme by the Japanese Atomic Energy Commission. The programme has been concentrated on the technological and economical feasibility and wholesomeness testings of seven irradiated food items of economic importance to the country, i.e. potatoes, onions, wheat, rice, 'kamaboko' (fish-paste products), 'Vienna' sausages and mandarin oranges. By now most studies, including wholesomeness testings of these irradiated food items, have been completed. In Japan, all foods or food additives for sale are regulated by the Food Sanitation Law enforced in 1947. Based on studies made by the national programme, irradiated potatoes were given 'unconditional acceptance' for human consumption in 1972. At present, irradiated potatoes are the only food item which has so far been approved by the Minister of Health and Welfare. Unless the Minister of Health and Welfare has declared that items are not harmful to human health on obtaining comments from the Food Sanitation Investigation Council, no irradiated food can be processed or sold. In addition, the import of irradiated foodstuffs other than potatoes from foreign countries is prohibited by law.

    In the early Meiji era, Takeaki Enomoto made a proposal to the government that cinchona and coffee seedlings be introduced to Japan. In response, the Meiji government dispatched Masatsugu Takeda of the Ministry of Internal Affairs to Java and India from March to August 1878 for the purpose of investigating useful plants of tropical origin and introducing them to Japan. This paper clarifies the route to those destinations and the plants obtained locally. Using the seeds obtained from India during his travels, the cultivation of cinchona was attempted in 1882 for the first time in Japan. In Ogasawara, coffee cultivation was conducted, again for the first time in Japan, using coffee seeds brought back from Java. The cultivation of coffee was successful and served as the foundation of the Ogasawara coffee that exists to this day. Takeda also introduced a number of books and materials related to useful tropical plants available as a result of his travels, which contributed to the promotion of new industries and businesses in the Meiji era.

    Dealing with the new road map published in 2009 by the NEDO (New Energy and Industrial Technology development Organization) for the research activity in photovoltaic electricity production in Japan from now until 2030, this brief embassy report first outlines the need for such a new road map as Japan's international competitiveness is more and more challenged: it only possesses 10% of the installed power in the world (50% in 2003) and ranks now in sixth position in terms of annual installed power. Beside this trend, environmental challenges and CO{sub 2} emission reduction objectives, as well as oil price increase, have driven the NEDO to review its road map sooner as foreseen. The author describes the contents of the three main axis which have been defined for the photovoltaic development: photovoltaic profitability improvement (grid parity objective by 2030, production cost reduction), broadening of photovoltaic uses and applications, development and competitiveness of Japanese industries.

    Japan-U.S. comparative research was made on technology transfer and innovative industry support. The U.S. industry is greatly benefited by universities, which is consequently strengthening the international competitiveness of the U.S. economy. However, the partnerships between private firms and universities have no fixed pattern, and keep changing dynamically. Business incubators increased to 627 rapidly, and mainly supported by municipal governments and universities. The U.S. has a well-established mechanism of technology transfer, and has succeeded in many cases. Not only universities but also national laboratories commit to technology transfer to venture businesses, and after starting businesses, entrepreneurs can use various hedging systems which are expected to play a role promoting the future technology innovation. The U.S. also has many advanced areas for sustainable technology innovation, like Silicon Valley, and these areas contain many supporting bodies to help new businesses. The activity of these bodies is very suggestive to Japanese local platforms promoting technology innovation and new local industry creation. Study was also made on the possibility of technology exchanges with overseas advanced areas. (NEDO)

    Development of rewetting correlation formula was the key to predict fuel-cladding temperature after Boiling Transition (BT). Japanese BWR utilities and vendors performed some tests of rewetting and made two rewetting correlation formulas. The effect on fuel integrity after BT depends on temperature of fuel rod and time of dryout. Main cause of losing fuel integrity during BWR's Anticipated Operational Occurrences (AOO) after BT is embrittlement of the claddings due to oxidation. Ballooning of fuel rod is excepted because its pressure boundary isn't broken. In Japan, the Standards Committee of Atomic Energy Society of Japan (AESJ) is making post BT standard. This standard provides guidelines based on the latest knowledge to judge fuel integrity in case of BT and the validity of reusing the fuel assembly that experienced BT in BWRs. (author)

    Caregiver burden (CB) of Alzheimer's disease (AD) in Taiwan is becoming an urgent social issue as well as that in Japan. The comparison of CB may explain how caregiver feels burden in each country. The participants were 343 outpatients with AD and their caregivers of Japan (n = 230) and Taiwan (n = 113). We assessed the CB using the Japanese and Chinese version of Zarit Caregiver Burden Interview (ZBI). The initial analysis was an exploratory factor analysis for each group to confirm the factor structure of ZBI. Then, the multiple-group structural equation modeling (MG-SEM) was used to assess the measurement invariance of ZBI such as configural, metric, and scalar invariances. Lastly, we compared the latent factor means of the ZBI between Japan and Taiwan. In both groups, the confirmatory factor analysis extracted 3 factors which were labeled "Impact on caregiver's life", "Embarrassed/anger", and "Dependency". The MG-SEM indicated an acceptable model fit, and established the partial scalar measurement invariance (comparative fit index (CFI) = 0.901, root mean square error of approximation (RMSEA) = 0.066). When we compared the latent factor means, the score of "Impact on caregiver's life" in Taiwanese caregivers was significantly higher than that in Japanese (p = 0.001). However, "Dependency" in Taiwanese caregivers was lower than that in Japanese (p Taiwan.

    This survey studied the feasibility of large-scale offshore wind power generation in Japan. Attempt was also made on preparation of outline maps of offshore wind around Japan. The cost of future offshore wind power generation systems is roughly dependent on technical issues and environmental issues. As technical issues, 'installation site,' 'foundation,' 'system interconnection' and 'maintenance/management' were summarized based on applications in Europe. As a result, it was clarified that technical issues can be solved with existing technologies to a certain extent, however, those relate to economical problems closely. The previous environment impact assessments say that wind power generation has no problems on the environmental issues. As relatively strong wind coastal areas, the outline maps of offshore wind point out Western Hokkaido area, Japan Sea area of Tohoku district, Pacific ocean area of the central part of Honshu, Genkai Nada area, Western Kyushu area and Southwest islands area, and suggest that these areas are promising for offshore wind power generation.

    The activity of Phase I of the Waste Management Working Group under the United States - Japan Joint Nuclear Energy Action Plan started in 2007. The US-Japan JNEAP is a bilateral collaborative framework to support the global implementation of safe, secure, and sustainable, nuclear fuel cycles (referred to in this document as fuel cycles). The Waste Management Working Group was established by strong interest of both parties, which arise from the recognition that development and optimization of waste management and disposal system(s) are central issues of the present and future nuclear fuel cycles. This report summarizes the activity of the Waste Management Working Group that focused on consolidation of the existing technical basis between the U.S. and Japan and the joint development of a plan for future collaborative activities. Firstly, the political/regulatory frameworks related to nuclear fuel cycles in both countries were reviewed. The various advanced fuel cycle scenarios that have been considered in both countries were then surveyed and summarized. The working group established the working reference scenario for the future cooperative activity that corresponds to a fuel cycle scenario being considered both in Japan and the U.S. This working scenario involves transitioning from a once-through fuel cycle utilizing light water reactors to a one-pass uranium-plutonium fuel recycle in light water reactors to a combination of light water reactors and fast reactors with plutonium, uranium, and minor actinide recycle, ultimately concluding with multiple recycle passes primarily using fast reactors. Considering the scenario, current and future expected waste streams, treatment and inventory were discussed, and the relevant information was summarized. Second, the waste management/disposal system optimization was discussed. Repository system concepts were reviewed, repository design concepts for the various classifications of nuclear waste were summarized, and the factors

    Currently, only three educational research reactors at two universities exist in Japan: KUR, KUCA of Kyoto University and UTR-KINKI of Kinki University. UTR-KINKI is a light-water moderated, graphite reflected, heterogeneous enriched uranium thermal reactor, which began operation as a private university No. 1 reactor in 1961. It is a low power nuclear reactor for education and research with a maximum heat output of 1 W. Using this nuclear reactor, researches, practical training, experiments for training nuclear human resources, and nuclear knowledge dissemination activities are carried out. As of October 2016, research and practical training accompanied by operation are not carried out because it is stopped. The following five items can be cited as challenges faced by research reactors: (1) response to new regulatory standards and stagnation of research and education, (2) strengthening of nuclear material protection and nuclear fuel concentration reduction, (3) countermeasures against aging and next research reactor, (4) outflow and shortage of nuclear human resources, and (5) expansion of research reactor maintenance cost. This paper would like to make the following recommendations so that we can make contribution to the world in the field of nuclear power. (1) Communication between regulatory authorities and business operators regarding new regulatory standards compliance. (2) Response to various problems including spent fuel measures for long-term stable utilization of research reactors. (3) Personal exchanges among nuclear experts. (4) Expansion of nuclear related departments at universities to train nuclear human resources. (5) Training of world-class nuclear human resources, and succession and development of research and technologies. (A.O.)

    Number of epilepsy patient in Japan officially surveyed by our government in 2008 is 219,000, which is only 0.17% of the total population and less than one third of the prevalence rate reported in Western countries. Number of epilepsy surgery per year in Japan is also low and less than half of other countries such as US, UK and Korea. These numbers may suggest that epilepsy care in Japan is not sufficient to cover all hidden medical needs of people with epilepsy at present. To solve this issue, our research group funded by the government have started to build an epilepsy care network among primary care physicians, secondary care neurology specialists and tertiary care epilepsy centers by utilizing a web site: Epilepsy Care Network-Japan (http://www.ecn-japan.com/) from July 2012. We are also proposing an epilepsy care algorithm suitable for our complex medical community consisted with various neurology specialists such as pediatric and adult neurologists, neurosurgeons and psychiatrists. Building Epilepsy Care Network in Japan may facilitate better medical and social support for people with epilepsy in Japan.

It defines whistleblowing as an act of the international nursing ethical ideal of advocacy, and places it in the larger context of professional responsibility. The experiences, actions, and ethical positions of 24 Japanese nurses regarding whistleblowing or reporting a colleague for wrongdoing provide the data. Of these respondents, similar in age, educational level and clinical experience, 10 had previously reported another nurse and 12 had reported a physician for a wrongful act. These data raise questions about overt actions to expose a colleague in a culture that values group loyalty and saving face. Additional research is needed for an in-depth understanding of whistleblowing, patient advocacy and professional responsibility across cultures, especially those that value group loyalty, saving face and similar concepts to the Japanese Ishin Denshin, where the value is on implicit understanding requiring indirect communication. Usually, being direct and openly discussing sensitive topics is not valued in Japan because such behavior disrupts the most fundamental value, harmony (wa).

  20. 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.

    I would like to congratulate INIS on its 45th anniversary. Japan is a founding member of this international cooperation program, and the Japan Atomic Energy Agency (formerly, Japan Atomic Energy Research Institute — JAERI) was appointed as the national center of INIS by the Japanese government. We have contributed to the collection, classification, indexing, abstracting and submission of nuclear literature published in our country, as well as promoted the INIS database within our country. I have been engaged in INIS activities for many years and have a lot of experience with INIS. On the occasion of INIS’ 45th anniversary, I would like to look back on this experience. I started my career at JAERI in 1984. The first regional training seminar for the Far East was held in Tokyo in October 1984. I was assigned to the Library Division of JAERI, but I worked as support staff for the regional training seminar. During the seminar, I had an opportunity to attend the technical tour with the seminar participants to the University of Library and Information Science, research laboratories, etc., in Tsukuba Science City. This was my first involvement with INIS. It was a very impressive and interesting experience

    The cohort of children in the western districts of the Bryansk Region of Russia exposed to radiation following the Chernobyl accident is described in this paper. The cohort was selected under the Joint Medical Research Project on Dosimetry Associated with the Chernobyl Accident conducted by Sasakawa Memorial Health Foundation (SMHF, Japan) and the Research Institute of Radiation Hygiene (RIRH, Russia). The subjects of the Research Project are those people residing in the most contaminated areas of Russia who was 0 to 10 years old at the time of exposure. At the moment the cohort comprises 1210 subjects, though this number may slightly decrease in course of a follow-up in view of migration of population. Most of cohort subjects were examined on their health status within the framework of the Chernobyl Sasakawa Health and Medical Cooperation Project (CSHMCP) from 1991-1996. In view of the main findings of studies in CSHMCP were thyroid abnormalities, selection of subjects was conducted on the basis of the credible estimates of thyroid dose. Preference for subjects to be included into the cohort was defined by the availability of health examination data from previous study (1991-1996) and individual dosimetry, environmental and social data that may prove useful for reconstruction of individual dose. The primary data analyzed for subjects selection are measurements of iodine-131 in the thyroid in May-June 1986, questionnaire data on individual food habits and early measurements of radiocesium in the body of subjects made by RIRH from May to September 1986. Plausible analytical models were applied to calculate thyroid dose from available data. Previously worked out methods of thyroid dose reconstruction using early measurement data of radiocesium content in the body and questionnaire data on individual consumption of locally produced milk were reevaluated. Basing on these analytical procedures, the individual thyroid dose was ascribed to each member of the cohort. The

    Accelerators have become to be used increasingly in Japan in such fields as medicine, physics research and industry. This has caused stiff competition for market share by the manufacturers of accelerators. Electron beam accelerators for industrial use provide an indispensable means for adding values to products, for example, electric cables with incombustible insulators. Linear accelerators for the nondestructive inspection of nuclear components have been widely installed at equipment manufacturing plants. Active efforts have been exerted to develop small synchrotron radiation accelerators for next generation electronic industry. Cyclotrons for producing short life radioisotopes for medical diagnosis and electron beam accelerators for radiation therapy are also used routinely. The suppliers of accelerators include the companies manufacturing heavy electric machinery, heavy machinery and the engineering division of steelmakers. Accelerator physics is being formed, but universities do not yet offer the course regarding accelerators. Accelerator use in Japan and the trend of accelerator manufacturers are reported. (K.I.)

    In deep geological disposal or intermediate depth disposal, human intrusion, i.e. accidental excavation or drilling into the disposal site, may make a direct or an indirect effect on the disposal system. Safety assessment method for the human intrusion scenario, that is, the evaluation code of radiological effect from the human intrusion and the data to examine the reduction of the probability of the human intrusion occurring, is essential for the future safety regulation. Assuming that drilling action into the disposal site leads to the human proximity to the radioactive waste or the damage to the barrier system (drilling scenario), we have collected both the data on borehole drilling implemented in Japan and information on actual situation of drilling activities. Based on the data and information, we provide concrete exposure scenarios associated with borehole drilling in the vicinity of the repository and model for estimating the frequency on borehole reaching the depth of repository. The frequency is characterized with the relation to objective of excavation, geographical features, and region in Japan etc. We have developed an assembly of the information mentioned above as database, including the model parameters used in the code to assess radiation dose for drilling scenario.

    2007-01-01

    In Japan, so-called a formal nuclear policy; The Framework for Nuclear Energy Policy is built up by Japan Atomic Energy Commission at every 5-year, in which not only a conventional light water reactor (LWR) but also a fast breeder reactor (FBR), HTGR and a fusion reactor (FR) is referred as a prominent candidate of long-term (<100 years) nuclear energy source. The policy makers might have multi-purpose scenarios for a future of innovated nuclear energy systems through results of various discussions at their level. According to long-term nuclear knowledge management, the author made ex ante evaluation of HTGR known as the intellectual assets of JAERI 1, from the viewpoint of hypothetical benefits under conditions of substantial uncertainty. Nuclear knowledge management (NKM) is an integrated, systematic approach to identifying, managing and sharing an organization's nuclear knowledge, and enabling persons to create new nuclear knowledge collectively and thereby helping achieve the objectives. NKM identifies, optimizes, and actively manages intellectual assets either in the form of explicit knowledge held in intangible products or tacit knowledge possessed by individuals or communities in the nuclear fields. In the present study the authors wish not only to show the validity of long-term NKM as a key factor of HTGR but also to assess their hypothetical benefits through the year 2050 under conditions of substantial uncertainty. It should be stressed that those factors are important intellectual assets of JAERI developed to date. Additionally, in the Framework for Nuclear Energy Policy constructed up by the Japan Atomic Energy Commission, a LWR, a fast breeder reactor (FBR), a HTGR, and a fusion reactor (FR) are all defined as eligible and prominent candidates for long-term nuclear energy sources. In this sense, we estimate here a direct market creation of (1) hydrogen energy production and (2) electricity generation, by commercialized HTGR through the year 2050 with

    In Japan, the field of Basic Sciences encompasses clinical, academic, and translational research, as well as the teaching of medical sciences, with both an MD and PhD typically required. In this study, it was hypothesized that the characteristics of a Basic Sciences career path could offer the professional advancement and personal fulfillment that many female medical doctors would find advantageous. Moreover, encouraging interest in Basic Sciences could help stem shortages that Japan is experiencing in medical fields, as noted in the three principal contributing factors: premature resignation of female clinicians, an imbalance of female physicians engaged in research, and a shortage of medical doctors in the Basic Sciences. This study examines the professional and personal fulfillment expressed by Japanese female medical doctors who hold positions in Basic Sciences. Topics include career advancement, interest in medical research, and greater flexibility for parenting. A cross-sectional questionnaire survey was distributed at all 80 medical schools in Japan, directed to 228 female medical doctors whose academic rank was assistant professor or higher in departments of Basic Sciences in 2012. Chi-square tests and the binary logistic regression model were used to investigate the impact of parenthood on career satisfaction, academic rank, salary, etc. The survey response rate of female physicians in Basic Sciences was 54.0%. Regardless of parental status, one in three respondents cited research interest as their rationale for entering Basic Sciences, well over twice other motivations. A majority had clinical experience, with clinical duties maintained part-time by about half of respondents and particularly parents. Only one third expressed afterthoughts about relinquishing full-time clinical practice, with physicians who were parents expressing stronger regrets. Parental status had little effect on academic rank and income within the Basic Sciences, CONCLUSION

    Highlights: > The specifications required for the analyses of the destructive assay data taken from irradiated fuel in Ohi-1 and Ohi-2 PWRs were documented in this paper. > These data were analyzed using the SWAT2.1 code, and the calculation results showed good agreement with experimental results. > These destructive assay data are suitable for the benchmarking of the burnup calculation code systems. - Abstract: The isotopic composition of spent nuclear fuels is vital data for studies on the nuclear fuel cycle and reactor physics. The Japan Atomic Energy Agency (JAEA) has been active in obtaining such data for pressurized water reactor (PWR) and boiling water reactor (BWR) fuels, and some data has already been published. These data have been registered with the international Spent Fuel Isotopic Composition Database (SFCOMPO) and widely used as international benchmarks for burnup calculation codes and libraries. In this paper, Assay Data of Spent Nuclear Fuel from two fuel assemblies irradiated in the Ohi-1 and Ohi-2 PWRs in Japan are shown. The destructive assay data from Ohi-2 have already been published. However, these data were not suitable for the benchmarking of calculation codes and libraries because several important specifications and data were not included. This paper summarizes the details of destructive assay data and specifications required for analyses of isotopic composition from Ohi-1 and Ohi-2. For precise burnup analyses, the burnup values of destructive assay samples were re-evaluated in this study. These destructive assay data were analyzed using the SWAT2.1 code, and the calculation results showed good agreement with experimental results. This indicates that the quality of destructive assay data from Ohi-1 and Ohi-2 PWRs is high, and that these destructive assay data are suitable for the benchmarking of burnup calculation code systems.

    The Japan Atomic Energy Research Institute (JAERI) was established in 1954, and immediately proceeded with the construction of a research reactor. The first symposium in Japan on nuclear energy was held in 1957. Most of the papers presented in the field of reactor shielding were limited to shielding materials and their fabrication. In the first stage of our investigations, our efforts were devoted to practical design studies of reactor shielding. As a result of these studies, it was found that the formulae at hand for calculations were inadequate, but at that time no electronic computer was available in Japan nor were theoretical calculations very actively undertaken. Problems on nuclear ship shielding had been investigated at the Ship Research Institute, since 1956 and many fruitful results had been obtained. About that time the Japan Atomic Industry Forum started activities and took the initiative in organizing shielding research. Research workers in the shipbuilding industry in particular have been seriously studying shielding problems. Few years after the first symposium, problems concerning more fundamental studies were treated by many research workers. Shielding experiments using radioisotopes were carried out and many fruitful results were obtained. They are described in the this paper. Medium size electronic computers became available in Japan, permitting a theoretical study group to make an active contribution. They produced some codes, and their results are also described in the following sections. This constituted the second stage of our investigations. A swimming-pool reactor, JRR-4 (Japan Research Reactor-4), has been under construction at JAERI since 1962 and will become critical in autumn 1964. After characteristic tests it will be a very powerful tool for the shielding investigations. This id the beginning of the third stage of investigations

    In September last year, the Japanese Government requested the International Atomic Energy Agency to supply three tons of natural uranium for a research reactor, and the Agency has now arranged for its sale to Japan. The metal will be supplied in ingot form and after fabrication it will be used as fuel in a reactor of the natural uranium, heavy water type. The uranium will be obtained from Canada and sold to Japan by IAEA. The Agency had invited tenders for its supply, and after considering the tenders received, the Agency's Board of Governors decided that the Canadian offer to the Agency of three tons of natural uranium free of charge should be accepted and that the selling price to Japan should be US $35. 50 per kilogramme. The price takes into account Article XIV/E of the Agency's Statute which says that the Agency shall establish a scale of charges (including those for storage and handling) for materials furnished to Member States, and that the scale shall be designed to produce revenues to meet expenses in connexion with materials acquired by the Agency and costs of materials and services provided by it under agreements with one or more members. This is the first operation of its kind to be undertaken by the Agency, and the reactor for which the supply is being made will be the first in Japan to be constructed by Japanese scientists and technicians. IAEA's Board of Governors has given the necessary approval to the reactor project for which the Agency is providing assistance

    Neutron capture cross sections of long-lived fission products (LLFP) are important quantities as fundamental data for the study of nuclear transmutation of radioactive wastes. Previously obtained thermal-neutron capture gamma-ray data were analyzed to deduce the partial neutron-capture cross sections of LLFPs including 99 Tc, 93 Zr, and 107 Pd for thermal neutrons. By comparing the decay gamma-ray data and prompt gamma-ray data for 99 Tc, the relation between the neutron-capture cross section deduced by the two different methods was studied. For the isotopes 93 Zr and 107 Pd, thermal neutron-capture gamma-ray production cross sections were deduced for the first time. The level schemes of 99 Tc, 93 Zr, and 107 Pd have also been constructed form the analyzed data and compared with previously reported levels. This work has been done under the cooperative program 'Neutron Capture Cross Sections of Long-Lived Fission products (LLFPs)' by Japan Nuclear Cycle Development Institute (JNC) and Oak Ridge National Laboratory (ORNL).

    Japan's effort to utilize plutonium for peaceful purpose since 1950s was caught in a cross fire after the end of the Cold War. Maritime transport of plutonium from France to Japan in 1993, for instance, was criticized by U.S. Congress, nonproliferation specialists and environmental activists. U.S. government, however, compiled with Japan-US Nuclear Cooperation Agreement and cooperated to ship plutonium. This paper focuses on why Washington was supportive for the sealift of plutonium despite of opposition against it. By solving the puzzle, this research will contribute to studies of Japan's plutonium policy and Japan-U.S. nuclear relations. Based on newspaper articles, memoirs and official documents, this paper examines backgrounds and features of controversy surrounding the transport. The analyses show the causes of U.S. cooperation to the transport, such as Japan's efforts toward nuclear nonproliferation. (author)

    The international and Japan's steel industry, the coking coal market, and Japan's expectations from Canada's coal industry are discussed. Japan's steel mills are operating at full capacity. Crude steel production for the first half of 2004 was 55.8 million tons. The steel mills are profitable, but costs are high, and there are difficulties with procuring raw materials. Japan is trying to enhance the quality of coke, in order to achieve higher productivity in the production of pig iron. Economic growth is rising disproportionately in the BRICs (Brazil, Russia, India, and China), with a large increase in coking coal demand from China. On the supply side, there are several projects underway in Australia and Canada to increase production. These include new developments by Elk Valley Coal Corporation, Grande Cache Coal, Western Canadian Coal, and Northern Energy and Mining in Canada. The Elga Mine in the far eastern part of Russia is under development. But the market is expected to remain tight for some time. Japan envisions Canadian coal producers will provide a stable coal supply, expansion of production and infrastructure capabilities, and stabilization of price. 16 slides/overheads are included.

    In Japan, the first food irradiation research was carried out on the preservation of fish and fishery products. In 1966, the Atomic Energy Commission of the Japanese Government (JAEC) decided to promote the National Project on Food Irradiation and, in 1967, the Steering Committee on food irradiation research in the Atomic Energy Bureau, Science and Technology Agency, selected the following food items as of economic importance to the country, i.e., potatoes, onions, rice, wheat, ''Vienna'' sausage, ''kamaboko'' (fish meat jelly products) and mandarin oranges. The National Project is expected to finish at the end of the 1981 fiscal year. Based on the studies by the National Project, irradiated potatoes were given ''unconditional acceptance'' for human consumption in 1972. Already in 1973, a commercial potato irradiator was built at Shihoro, Hokkaido. In 1980, the Steering Committee submitted a final report on the effectiveness and wholesomeness studies on irradiated onions to the JAEC. This paper gives a brief explanation of the legal aspects of food irradiation in Japan, and the present status of wholesomeness studies on the seven items of irradiated foods. In addition, topics concerning food irradiation research on ''kamaboko'', especially on the effectiveness and a new detecting method for the irradiation treatment of these products, are outlined.

    In October 2005, the Japan Atomic Energy Agency (JAEA) was established as an independent administrative institution with the integration of the Japan Atomic Energy Research Institute (JAERI) and the Japan Nuclear Cycle Development Institute (JNC). JAEA is the only institute in Japan dedicated to comprehensive research and development in the field of nuclear energy. This paper put together a special article on its role and expectation. Firstly the essentials of comprehensive nuclear research and its future perspective were discussed mainly based on 'Framework for Nuclear Energy Policy' of the Atomic Energy Commission of Japan. Eight articles were followed on specific items such as quantum beams utilization, hydrogen production with nuclear heat, neutron science and ITER project, and put stress on joint works and smooth transfer of related technology to the private sector.

    1984-01-01

    A summary of nuclear energy in Japan is presented. Nuclear energy provides 17% of Japan's electricity but could provide much more. 25 more reactors (to add to the existing 27) are planned by 1995. The cooperation between Japanese government and industry and the economic assistance in building new plants means that these are not likely to be cancelled. Public acceptance of new plants has often been obtained by large cash employment inducements. Now, however, there is growing disillusionment when short-term well paid employment building the reactors is followed by unemployment when the reactor is in operation. Also there is a growing opposition to the storage of the nuclear waste. To maintain the growth of its nuclear industry Japan needs to export to provide a steady flow of big orders. (U.K.)

    Like health care systems in other developed countries, Japan's health care system faces significant challenges due to aging of the population and economic stagnation. Advanced medicine (Senshin Iryou) is a unique system of medical care in Japan offering highly technology-driven medical care that is not covered by public health insurance. Advanced medicine has recently developed and expanded as part of health care reform. Will it work? To answer this question, we briefly trace the historical development of advanced medicine and describe the characteristics and current state of advanced medical care in Japan. We then offer our opinions on the future of advanced medicine with careful consideration of its pros and cons. We believe that developing advanced medicine is an attempt to bring health care reform in line rather than the goal of health care reform.

    There are growing tensions and frictions between the U.S. and Japan. Among them are science and technology issues that relate to the development of superconductor technology, as well as economic, trade and agricultural issues. The structure of this friction is very complex. There are many interconnected issues that cannot be resolved one by one. This article focuses on the relationship between the U.S. and Japan. Some of the complexities behind the issues are discussed by defining different notions of internationalization and by presenting the positive and negative aspects of the Japanese approach that affects the future cooperation and competition between our nations in the area of superconductivity

    1990-10-01

    Data from the 1985-86 Japanese census are analysed to explore the determinants of the divorce rates in Japan's forty-seven prefectures, using two theoretical models: (a) the social integration model, which is shown to have a greater utility in predicting Japanese divorce levels than (b), the human capital model. Female emigration patterns play a significant role in affecting the divorce rate. Population increase and net household income are also important predictors of the Japanese divorce rate and urbanization has a great influence in modern Japan. Demographic and aggregate variables such as migration, urbanization, and socioeconomic factors are useful when organized under a social integration model.

    2009-07-01

    Japan's Iwatani Corporation has focused its attention on hydrogen as the ultimate energy source in future. Unlike the United States, hydrogen use and delivery in liquid form is extremely limited in the European Union and in Japan. Iwatani Corporation broke through industry stereotypes by creating and building Hydro Edge Co. Ltd., Japan's largest liquid hydrogen plant. It was established in 2006 as a joint venture between Iwatani and Kansai Electric Power Group in Osaka. Hydro Edge is Japan's first combined liquid hydrogen and ASU plant, and is fully operational. Liquid oxygen, liquid nitrogen and liquid argon are separated from air using the cryogenic energy of liquefied natural gas fuel that is used for power generation. Liquid hydrogen is produced efficiently and simultaneously using liquid nitrogen. Approximately 12 times as much hydrogen in liquid form can be transported and supplied as pressurized hydrogen gas. This technology is a significant step forward in the dissemination and expansion of hydrogen in a hydrogen-based economy.

    Tummala, Rao R.; Pecht, Michael

    1995-02-01

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

    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. PMID:28082761

    2006-01-01

    A goal of the 21. century is for society to pursue 'sustainable economic development and prosperous life by recycling resources', thus rejecting 'development based on the waste of resources'. For Japan, which has limited energy resources, it is important to secure safe, inexpensive, environmentally friendly energy resources having long-term availability. To contribute to long-term energy security and solve global environmental issues, and to create advanced competitive science and technology, the Japan Atomic Energy Agency (JAEA) was established by integrating the Japan Atomic Energy Research Institute (JAERI) and the Japan Nuclear Cycle Development Institute (JNC) in October 2005. JAEA is endeavoring to establish nuclear fuel cycles, to contribute to social improvement through hydrogen production initiated by atomic energy, and to pursue research and development of thermonuclear fusion and quantum beam technology. This paper reviews the main R and D activities of JAEA. The structure of the paper is the following: 1. Introduction; 2. Japan Atomic Energy Agency; 3. Efforts to Commercialize the Fast Reactor Cycle; 4. Monju Progress; 5. Geological Disposal of High-Level Radioactive Waste R and D; 6. High Temperature Gas-Cooled Reactor System R and D; 7. Fusion Research and Development; 8. LWR Spent Fuel Reprocessing Technology; 9. Quantum Beam Technologies; 10. Nuclear Safety Research and Regulatory Applications; 11. Basic Science and Engineering Research; 12. Contribution to the Enhanced International Nonproliferation Regimes; 13. Conclusions. To summarize, JAEA will promote the above R and D activities, addressing the following commitments: - On problems that atomic energy faces, we shall extend technical assistance in response to the government and the industrial sectors. - We shall produce technical options to attain political goals to secure medium to long-term stable energy supplies and to solve global environmental issues. - With the high potentials of atomic

    2012-11-15

    Currently, many smart grid projects are running or planned worldwide. These aim at controlling the electricity supply more efficiently and more stably in a new power network system. In Japan, especially superconductivity technology development projects are carried out to contribute to the future smart grid. Japanese cable makers such as Sumitomo Electric and Furukawa Electric are leading in the production of high-temperature superconducting (HTS) power cables. The world's largest electric current and highest voltage superconductivity proving tests have been started this year. Big cities such as Tokyo will be expected to introduce the HTS power cables to reduce transport losses and to meet the increased electricity demand in the near future. Superconducting devices, HTS power cables, Superconducting Magnetic Energy Storage (SMES) and flywheels are the focus of new developments in cooperations between companies, universities and research institutes, funded by the Japanese research and development funding organization New Energy and Industrial Technology Development Organization (NEDO)

    1976-01-01

    The development of nuclear merchant ship in Japan was started in 1955 by the establishment of Nuclear Ship Study Group, and since then, the investigation, test and research on nuclear ships have been continued. As a result, a nuclear ocean observation and supply ship was designed for trial. Researches were carried out also in JAERI and Institute for Technical Research of Ships. Meanwhile, the nuclear icebreaker Lenin was completed in Soviet Union in 1959, the nuclear ship Savannah set out for maiden voyage in U.S. in 1962, and the construction of the nuclear ore carrier Otto Hahn was prepared in FRG. Japan Nuclear Ship Development Corp. was established in 1963, and started the design and construction of the first nuclear ship in Japan, Mutsu. The basic policy in the construction is the improvement of nuclear ship technology, the securing of safety, and the use of domestic technologies as far as possible. The progress of the design, construction and test of the Mutsu is described. Owing to the problem of radiation leak, the development of nuclear ships stagnated for a while, but the nuclear plant of the Mutsu demonstrated the expected performance in the functional test, land criticality test and zero output test, and it is expected that the bud of the independent development brought up so far can bear valuable fruit. The independent development of marine nuclear reactors should be continued by selecting the way most suitable to Japan. (Kako, I.)

    Military aspect of nuclear policy of Japan was outlined. In 1952 Prime Minister Yoshida asked to prepare production of weapons for rearmament and to establish Science and Technology Agency such as to overcome lack of science research budget and inefficiency of research and cooperation. Kaya and Fushimi proposed establishment of Atomic Energy Commission as recommendation of Science Council of Japan. In 1954 Nakasone proposed budget for nuclear energy with yen 235 million to construct reactor. In 1955 Japanese delegation participated in international conference on peaceful use of nuclear energy at Geneva and nonpartisan members proposed Atomic Energy Basic Law, which limited the use of nuclear technology to peaceful purposes, ensured three principles - democratic methods, independent management, and transparency - as the basis of nuclear research and promoted international co-operation. In 1956 Atomic Energy Commission and Science and Technology Agency were established with other organizations under this law. According to internal report in the age of Prime Minister Sato, nuclear policy in Japan would be (1) no holding nuclear weapon for the time being, (2) maintaining economic and technical potential of nuclear weapon production and (3) considering no restraint for this policy whether Japan participated in NPT or not. Fuel cycle program of Monju reactor and reprocessing for power production seemed to be deployed corresponding to (3) above. Irradiated blanket of Monju reactor could be reprocessed to produce highly purified plutonium suited for nuclear bombs. (T. Tanaka)

    2011-01-01

    The Great East Japan Earthquake on March 11, 2011 has catastrophic impacts on Japan. Japan is currently on the way to recovery. However, as the damage on the country as well as society is so serious, Japanese society is urged to change some systems including hazard management, energy policy, information systems and city planning. These changes are accompanied with social group realignments, thus necessarily followed by various risks. To cope with these risk issues, SRA-Japan established the special research committee for the Great East Japan Earthquake. The aim of the committee is, from viewpoints of risk analysts, to create and relate messages about risk issues in 2-3 years, in ten years and in thirty years from the earthquake. To do this, the committee garners SRA-Japan member's opinions about possible risks in Japan by using Delphi method. In SRA-Japan, there are over 600 members in interdisciplinary fields from various backgrounds, thus the messages are expected to be helpful for Japanese society to lower its risks and to optimize the resource allocation. The research is now underway. An interim report will be presented. (author)

  11. The electronuclear program of Japan

    1978-01-01

    Japan, depending on imports for 80% of its energy supply, introduced a nuclear power program, which now comprises 14 reactors in operation (8,000 MW., that is 8% of its electricity production), and 15 reactors (14,000MW) under construction or being investigated. The objective for 1985 is from 26,000 to 33,000 MW. Japanese industry committed the error of placing too much confidence in its American licensers and not undertaking enough of its own research. This resulted in having a too small number of nuclear stations available, approximately 50%. Japan secured its uranium supply (Niger), its enrichment facilities (U.S.A. and Eurodif), while studying the centrifugation process, and facilities for reprocessing irradiated fuels (France and U.K.) while, at the same time, seeking national independence regarding its entire fuel cycle. The siting of nuclear power stations comes up against local opposition, which is being overcome by a taxation on electricity used to subsidize local collectivities favorable to the construction of a power station, whether hydro-electric, thermal or nuclear [fr

    Gambling disorder is a psychiatric disorder characterized by persistent and recurrent problematic gambling behavior, associated with impaired functioning, reduced quality of life, and frequent divorce and bankruptcy. Gambling disorder is reclassified in the category Substance-Related and Addictive Disorders in the DSM-5 because its clinical features closely resemble those of substance use disorders, and gambling activates the reward system in brain in much the same way drugs do. Prevalence of gambling disorder in Japan is high rate because of slot machines and pachinko game are very popular in Japan. The author recommend group psychotherapy and self-help group (Gamblers Anonymous), because group dynamics make them accept their wrongdoings related to gambling and believe that they can enjoy their lives without gambling.

    1998-01-01

    Current Japanese State System for Accountancy and Control (SSAC) has been developing and fully satisfies requirements of both IAEA Safeguards and bilateral partners. However, the public attention on the national and international safeguards activities were increased and the safeguards authorities were required to promote the objective assessment of safeguards implementation to avoid mistrust in safeguards activities which directly influence the public acceptance of nuclear energy in itself. Additionally, since Japan has promoted to complete nuclear fuel cycle including spent fuel reprocessing, enrichment and mixed oxide fuel fabrication this would require further assurance of Japanese non-proliferation commitment. Japan supports the introduction of strengthened safeguards. In this context it is particularly important to strengthen the relationship between national and the IAEA safeguards to contribute actively to the IAEA safeguards in development and utilization of new technologies towards more effective and efficient IAEA safeguards

    Particle confinement was compared for the high confinement mode plasmas with the edge localized mode in the Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-60U) [S. Ishida, JT-60 Team, Nucl. Fusion 39, 1211 (1999)] and the DIII-D tokamak [J. L. Luxon et al., Plasma Physics and Controlled Nuclear Fusion Research 1986 (International Atomic Energy Agency, Vienna, 1987), Vol. 1, p. 159] considering separate confinement times for particles supplied by neutral beam injection (NBI) (center fueling) and by recycling and gas-puffing (edge fueling). Similar dependence on the NBI power was obtained in JT-60U and DIII-D. The particle confinement time for center fueling in DIII-D was smaller by a factor of 4 in the low density discharges and by a factor of 1.8 in the high density discharges than JT-60U scaling, respectively, suggesting the stronger dependence on the density in DIII-D. The particle confinement time for edge fueling in DIII-D was comparable with JT-60U scaling in the low density discharges. However, it decreased to a much smaller value in the high density discharges

The plan was approved by AEC, and is to be incorporated in the 'Long term program for development and utilization of nuclear energy' up for revision next year. The report on 'Nuclear fuel recycling in Japan' by the committee is characterized by Japanese nuclear fuel recycling plan and the supply-demand situation for plutonium, the principle of the possession of plutonium not more than the demand in conformity with nuclear nonproliferation attitude, and the establishment of a domestic fabrication system of uranium-plutonium mixed oxide fuel. The total plutonium supply up to 2010 is estimated to be about 85 t, on the other hand, the demand will be 80-90 t. The treatment of plutonium is the key to the recycling and utilization of nuclear fuel. By around 2000, the private sector will commercialize the fabrication of the MOX fuel for LWRs at the annual rate of about 100 t. Commitment to nuclear nonproliferation, future nuclear fuel recycling program in Japan, MOX fuel fabrication system in Japan and so on are reported. (K.I.)

    The 70-year history of scientific endeavor of solid state ionics research in Japan is reviewed to show the contribution of Japanese scientists to the basic science of solid state ionics and its applications. The term 'solid state ionics' was defined by Takehiko Takahashi of Nagoya University, Japan: it refers to ions in solids, especially solids that exhibit high ionic conductivity at a fairly low temperature below their melting points. During the last few decades of exploration, many ion conducting solids have been discovered in Japan such as the copper-ion conductor Rb4Cu16I7Cl13, proton conductor SrCe1-xYxO3, oxide-ion conductor La0.9Sr0.9Ga0.9Mg0.1O3, and lithium-ion conductor Li10GeP2S12. Rb4Cu16I7Cl13 has a conductivity of 0.33 S cm-1 at 25 °C, which is the highest of all room temperature ion conductive solid electrolytes reported to date, and Li10GeP2S12 has a conductivity of 0.012 S cm-1 at 25 °C, which is the highest among lithium-ion conductors reported to date. Research on high-temperature proton conducting ceramics began in Japan. The history, the discovery of novel ionic conductors and the story behind them are summarized along with basic science and technology.

    This paper investigates social policies concerning men's transitions to fatherhood and the changing role of fathers in Japan. A review of fathering research reveals a predominantly agency-level emphasis on role-strain between work and paternal identities with a specific discourse of weakened Japanese fatherhood. Previous research suggested Japanese gender equality and work-life balance initiatives stalled due to an absence of women's influence within Japan's corporate culture. This study offe...

    This paper introduces the circumstances and purpose of establishing the Basic Research Associate for Innovated Coal Utilization (BRAIN-C) Program started in October 1995, and the summary of the results therefrom in fiscal 1995. Although development of coal utilization technologies has been implemented over a number of years, there are many problems still requiring solutions. Early realization has been urged on diversification of coal utilization, acceleration of technological development and diversification of coal types. In order to achieve these goals, the necessity was recognized afresh on not only the hardwares, but also on basic technologies in terms of software which can identify properties of coals, systematize different reactions, and estimate reactions, fluidity and heat transmission of coals. Therefore, receiving a subsidy from the Agency of Natural Resources and Energy of the Ministry of International Trade and Industry, a research and development program to be implemented jointly by industries, administrative agencies and academic societies had been started with a five-year plan for the time being. With the activities for the program such as collecting 50 to 100 types of coals and supplying them to researchers, the program had been accelerated in fiscal 1995 on a large number of themes and results therefrom, including fundamental properties and thermo-chemical reactions. 2 figs., 4 tabs.

    Within JAERI, funds invested in a 45-year study of LWR totaled 4.2b$ for research and 3.4b$ (34,718 man years) for personnel. The benefits to taxpayers from this JAERI work were estimated to be about 6.3b$ , resulting in a favorable cost-benefit ratio of 1.5 (6.3/4.2). JAERI is a national research institute and this figure may be regarded as sufficiently high, and many high risk and complex tasks were completed successfully. Funds invested in the 32-year study of HTGR were 1.5b$ for R and D and 0.3b$ (2966 man years) for personnel. Commercialized HTGR will result in a cost reduction of electricity during power generation. Retail cost is 0.36b$/year and the share of JAERI (MCP) is 0.018b$/year. Funds invested in the 32-year study of FR were 5.4b$ for R and D and 0.6b$ (6331 man years) for personnel. Estimate is that after commercialization in 2050, a FR will generate revenue from electricity as high as 1687b$ during the period 2050-2100, or 34b$/year - which is greater than that of LWR. However, there is substantial uncertainty in these estimates. To achieve long-term INES, it is necessary to develop the sustainable scenarios and the long-term robust NKM, as shown in the present study. (author)

    To investigate the associations between psychosocial factors and the development of chronic disabling low back pain (LBP) in Japanese workers. A 1 yr prospective cohort of the Japan Epidemiological Research of Occupation-related Back Pain (JOB) study was used. The participants were office workers, nurses, sales/marketing personnel, and manufacturing engineers. Self-administered questionnaires were distributed twice: at baseline and 1 yr after baseline. The outcome of interest was the development of chronic disabling LBP during the 1 yr follow-up period. Incidence was calculated for the participants who experienced disabling LBP during the month prior to baseline. Logistic regression was used to assess risk factors for chronic disabling LBP. Of 5,310 participants responding at baseline (response rate: 86.5%), 3,811 completed the questionnaire at follow-up. Among 171 eligible participants who experienced disabling back pain during the month prior to baseline, 29 (17.0%) developed chronic disabling LBP during the follow-up period. Multivariate logistic regression analysis implied reward to work (not feeling rewarded, OR: 3.62, 95%CI: 1.17-11.19), anxiety (anxious, OR: 2.89, 95%CI: 0.97-8.57), and daily-life satisfaction (not satisfied, ORs: 4.14, 95%CI: 1.18-14.58) were significant. Psychosocial factors are key to the development of chronic disabling LBP in Japanese workers. Psychosocial interventions may reduce the impact of LBP in the workplace.

    This paper describes the Japan Meteorological Agency/Meteorological Research Institute-Coupled Prediction System version 2 (JMA/MRI-CPS2), which was put into operation in June 2015 for the purpose of performing seasonal predictions. JMA/MRI-CPS2 has various upgrades from its predecessor, JMA/MRI-CPS1, including improved resolution and physics in its atmospheric and oceanic components, introduction of an interactive sea-ice model and realistic initialization of its land component. Verification of extensive re-forecasts covering a 30-year period (1981-2010) demonstrates that JMA/MRI-CPS2 possesses improved seasonal predictive skills for both atmospheric and oceanic interannual variability as well as key coupled variability such as the El Niño-Southern Oscillation (ENSO). For ENSO prediction, the new system better represents the forecast uncertainty and transition/duration of ENSO phases. Our analysis suggests that the enhanced predictive skills are attributable to incremental improvements resulting from all of the changes, as is apparent in the beneficial effects of sea-ice coupling and land initialization on 2-m temperature predictions. JMA/MRI-CPS2 is capable of reasonably representing the seasonal cycle and secular trends of sea ice. The sea-ice coupling remarkably enhances the predictive capability for the Arctic 2-m temperature, indicating the importance of this factor, particularly for seasonal predictions in the Arctic region.

    This report, compiled by the Nuclear Safety Commission to be submitted to the Prime Minister, deals with studies concerning some changes in the plan for the installation of a nuclear reactor in the No.1 atomic powered vessel to be constructed under the Japan Atomic Energy Research Institute (changes in the purpose of its use and in the methods for the nuclear reactor installation and spent fuel disposal). The conclusions of and procedures for the examination and evaluation are presented and then detailes of the studies are described. The study on the location requirements for the incidental land facilities at Sekinehama covers various conditions concerning the location, geology, earthquakes, meteorology, hydrology and social environment. The study on the safety design of the nuclear reactor facilities deals with the reactor, fuel handling facilities and other auxiliary facilities, as well as various land facilities to be constructed at Sekinehama including the reactor facilities and other facilities for fuel handling, waste disposal and protection and management of radioactive rays. Evaluation of possible radiation emission is shown and the accident analysis is also addressed. (Nogami, K.)

  15. Beam loss caused by edge focusing of injection bump magnets and its mitigation in the 3-GeV rapid cycling synchrotron of the Japan Proton Accelerator Research Complex

    2016-01-01

    Full Text Available In the 3-GeV rapid cycling synchrotron of the Japan Proton Accelerator Research Complex, transverse injection painting is utilized not only to suppress space-charge induced beam loss in the low energy region but also to mitigate foil scattering beam loss during charge-exchange injection. The space-charge induced beam loss is well minimized by the combination of modest transverse painting and full longitudinal painting. But, for sufficiently mitigating the foil scattering part of beam loss, the transverse painting area has to be further expanded. However, such a wide-ranging transverse painting had not been realized until recently due to beta function beating caused by edge focusing of pulsed injection bump magnets during injection. This beta function beating additionally excites random betatron resonances through a distortion of the lattice superperiodicity, and its resultant deterioration of the betatron motion stability causes significant extra beam loss when expanding the transverse painting area. To solve this issue, we newly installed pulse-type quadrupole correctors to compensate the beta function beating. This paper presents recent experimental results on this correction scheme for suppressing the extra beam loss, while discussing the beam loss and its mitigation mechanisms with the corresponding numerical simulations.

  18. What is nuclear power in Japan?

    Science.gov (United States)

    Suzuki, Toshikazu

    2011-03-01

    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.

  19. The graying of Japan.

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

  20. Japan's spent fuel and plutonium management challenge

    2011-01-01

    Japan's commitment to plutonium recycling has been explicitly stated in its long-term program since 1956. Despite the clear cost disadvantage compared with direct disposal or storage of spent fuel, the Rokkasho reprocessing plant started active testing in 2006. Japan's cumulative consumption of plutonium has been only 5 tons to date and its future consumption rate is still uncertain. But once the Rokkasho reprocessing plant starts its full operation, Japan will separate about 8 tons of plutonium annually. Our analysis shows that, with optimum use of available at-reactor and away-from-reactor storage capacity, there would be no need for reprocessing until the mid-2020s. With an additional 30,000 tons of away-from-reactor (AFR) spent-fuel storage capacity reprocessing could be avoided until 2050. Deferring operation of the Rokkasho plant, at least until the plutonium stockpile had been worked down to the minimum required level, would also minimize international concern about Japan's plutonium stockpile. The authors are happy to acknowledge Frank von Hippel, Harold Feiveson, Jungming Kang, Zia Mian, M.V. Ramana, and other IPFM members, as well as the generous grant from the MacArthur Foundation for helping make this research possible.

    Fukatsu, Takema

    Here I present an overview of entomological journals and publishing in Japan, thereby providing a convenient portal to the valuable scientific resources for the world's entomological researchers and scientific communities. Currently, except for several international journals published fully in English such as Applied Entomology and Zoology and Entomological Science , many entomological and entomology-related journals in Japan are not indexed by major scientific databases like Web of Science, and therefore they are neither conveniently recognizable nor accessible for the world's entomological communities. However, I point out that many of the contents of such journals are freely available via Japan's public platforms for electronic scientific literature, Japan Science and Technology Information Aggregator, Electronic (J-stage) or Citation Information by National Institute of Informatics (CiNii). Here I list 32 entomological and entomology-related societies and their 45 journals, the majority of which belong to either the Union of Japanese Societies for Insect Sciences (UJSIS), the Union of the Japanese Societies for Systematic Biology (UJSSB), the Union of Japanese Societies for Natural History (UJSNH), or the Union of Japanese Societies for Biological Science (UJSBS), with their respective URL and open-access availability.

  5. Theorizing School Bullying: Insights from Japan

    Directory of Open Access Journals (Sweden)

    Shoko Yoneyama

    2015-08-01

    Full Text Available This paper identifies a lacuna in the existing paradigms of bullying: a gap caused by the frame of reference being largely limited to the highly industrialized societies of the 'west': Europe, North America and Oceania. The paper attempts to address this gap by presenting research developed in Japan. In Japan, sociological discourse on school bullying, i.e. the analysis of institutional factors relevant to understanding bullying was established relatively early, as was the epistemology now referred to as the second paradigm of bullying. The paper attempts to integrate the research strengths of Japan with this new trend in bullying research, with the view of incorporating 'non-western' research traditions into mainstream discourse on bullying. It introduces a typology of school bullying: Types I and II, and discusses 1 hierarchical relationships in schools, focusing on corporal punishment and teacher-student bullying, and 2 group dynamics surrounding bullying. The paper illustrates how bullying among students is entwined with various aspects of schools as social institutions. It argues that school bullying may represent a state of anomie in both formal and informal power structures in schools, which have become dysfunctional communities unable to deal with bullying, while at the same time it can be students' way of compensating their sense of alienation and disconnectedness from school.

    To provide an integrative review of literature on health communication in East Asia and detail culturally-specific influences. Using PRISMA model, search of PubMed, PsychInfo, Web of Knowledge, ERIC and CINAHL databases were conducted for studies between January 2000 and March 2017, using the terms 'clinician/health professional-patient', 'nurse/doctor-patient, 'communication' and 'Asia'. 38 studies were included: Mainland China, Hong Kong, Japan, South Korea, and Taiwan. The existing body of research on clinician patient communication in East Asia can be classified: 1) understanding the roles and expectations of the nurse, clinician, patient, and family in clinician-patient consultations: a) nurse-patient communication; b) doctor-patient communication; c) the role of family member; and 2) factors affecting quality of care: d) cultural attitudes towards death and terminal illnesses; e) communication preferences affecting trust, decision-making and patient satisfaction; f) the extent to which patient centred care is being implemented in practice; and g) communication practices in multilingual/multi-disciplinary environments. The review detailed the complexity and heterogeneity of clinician-patient communication across East Asia. The studies reviewed indicate that research in East Asia is starting to move beyond a preference for Western-based communication practices. There is a need to consider local culture in understanding and interpreting medical encounters in East Asia. The paper highlights the need for a specific culturally-appropriate model of health communication in East Asia which may significantly improve relationships between clinicians and patients.

  9. Legalized abortion in Japan.

    Science.gov (United States)

    Hart, T M

    1967-10-01

    The enactment of the Eugenic Protection Act in Japan was followed by many changes. The population explosion was stemmed, the birth rate was halved, and while the marriage rate remained steady the divorce rate declined. The annual total of abortions increased until 1955 and then slowly declined. The highest incidence of abortions in families is in the 30 to 34 age group when there are four children in the family. As elsewhere abortion in advanced stages of pregnancy is associated with high morbidity and mortality. There is little consensus as to the number of criminal abortions. Reasons for criminal abortions can be found in the legal restrictions concerning abortion: Licensing of the abortionist, certification of hospitals, taxation of operations and the requirement that abortion be reported. Other factors are price competition and the patient's desire for secrecy. Contraception is relatively ineffective as a birth control method in Japan. Oral contraceptives are not yet government approved. In 1958 alone 1.1 per cent of married women were sterilized and the incidence of sterilization was increasing.

  10. Waste inventory, waste characteristics and waste repositories in Japan

    There are two types of repositories for the low level radioactive wastes in Japan. One is a trench type repository only for concrete debris generated from the dismantling of the research reactor. According to the safety assurance system, Japan Atomic Energy Research Institute (JAERI) has disposed of the concrete debris arose from the dismantling of the Japan Power Demonstration Reactor (JPDR). The other type is the concreted pit with engineered barriers. Rokkasho Low Level Radioactive Waste Disposal Center has this type of repository mainly for the power plant wastes. Japan Nuclear Fuel Ltd. (JNFL) established by electric power companies is the operator of the LLW disposal project.

  15. Japan and atomic co-operation

    International Nuclear Information System (INIS)

    1965-01-01

    Japan, which is host country for the Ninth Regular Session of the Agency General Conference, has an important programme of nuclear power development to meet future needs. In addition, Japan is active in other applications of atomic energy and is building up a domestic nuclear engineering industry. Japan has profited by the Agency as a channel of international cooperation, and was a party to the first bilateral agreement in which the responsibility for administering safeguards against the diversion of materials to military purposes, was transferred to the Agency. Japan has also lent support to Agency programmes by gifts, training courses, research, and the loan of experts. In 1961, the Japan Atomic Energy Commission (AEC) formulated the 'Long-Range Programme for Development and Utilization of Atomic Energy', on the basis of the economic prospects of nuclear power generation, and the conditions necessary to meet the ever-increasing domestic energy demands. According to this programme, in the light of power reactor development trends overseas, it is expected that nuclear power costs will compete with those of oil burning stations by 1970. On this basis, total nuclear power generating capacity of 1000 MW(e) will be attained by 1970, and 7000 - 9 500M(e) by 1980. As a prelude to the above programme the Japan Atomic Power Company (JAPCO) began construction in 1959 of a graphite-moderated gas-cooled nuclear power station (Improved Calder Hall type) of 165 MW(e) gross capacity. This is now progressing smoothly, and reached criticality in May 1965; it is expected to supply commercial power by the end of this year. The second nuclear power station will be built by the same company on the coast of the Japan Sea, with a light water-moderated reactor of 250 - 300 MW(e) capacity. The construction plan i s currently being pushed forward for completion in 1970. Thereafter three private utility companies - Tokyo, Kansai and Chubu Electric Companies - are doing preparatory work for

    THE FIRST EUROPEANS to discover Japan were Portuguese traders who arrived in 1542. Fifteen years later, the Portuguese Jesuit priest and surgeon Luis De Almeida (1525-1583) founded the first Western hospital in Japan, for the care of lepers, syphilitics, and orphans. Because the hospital had a negative influence on the spread of Christianity, the Jesuits closed it in 1586. During the Tokugawa Shogunate (1600-1868), when Japan was secluded from the rest of the world, the only foreign physicians allowed to enter Japan were those employed by the Dutch factory at Dejima in Nagasaki. Only four of those physicians left behind seeds for the foundation of Western medicine in Japan, namely Caspar Schambergen, who founded a Japanese school of surgery in 1650; Engelbert Kämpfer, who visited Japan in 1691 to 1692; Carl Peter Thunberg, who botanically explored Japan in 1775 to 1776; and Philipp Franz Balthasar von Siebold, who practiced medicine in Nagasaki in 1823 to 1829 and 1859 to 1861. On the whole, Western medicine and surgery never established a real foothold in Japan until the fall of the shogunate and the restoration of the emperor in 1868.

    2001-01-01

    A research development of nuclear fusion was divided four periods: the first period as prehistory (until about 1955), the second period as begin of research (1955 to 1969), the third as the growth period (1970 to 1985) and the forth as the large tokamak age. In this paper I explained the second period, because general physicists and young plasma and controlled nuclear fusion researcher did not know about this period. The controlled nuclear fusion research was begun by the experiment of hydrogen bomb by USA and USSR in 1952 and 1953. In Japan, on the basis of many societies, 'The Controlled Nuclear Fusion Meeting' was established as an independent system and KAKEA (Journal of Fusion Research) was published in 1958. Japan government began to make the system by the Nuclear Commission in 1957. The main research devices in 1962 were linear pinch, mirror device, toroidal pinch, helical system, plasma gun and plasma measurement. USSR showed the excellent results of tokamak device in 1968. Ookawa spoke the effect of the average minimum-B, the best report in this period, at the second IAEA meeting, 1965. JAERI constructed JFT-1 and JFT-2, the latter was the first class device in the world and made the first step of Japanese research into the world, for examples, to attain the equilibrium of divertor plasma and to control impurity. Many research centers of controlled fusion were established in many universities in Japan from 1966 to 1980. Cooperation researchs between Japan and USA, USSR and many countries has been carried out after 1978: JIFT (Joint Institute for Fusion Theory) and FPPC (Fusion Power Coordinating Committee). The important results increased in this period. After 1985, the research activities are processing and data increased very fast depend on the larger devices and system, good measurement system and development of information system. JT-60 in JAERI opened to the large tokamak period. It led controlled fusion researchs in the world the same as TFTR (US

    Abstract: After coming back to Japan to work in the Department of Physics at the University of Tokyo, Yoshiki Hotta spent a year or so on searching for behavioral mutants of goldfish. Although this endeavor did not succeed, he remained an adamant supporter of the development of zebrafish research in Japan. Here we review how his support helped zebrafish neurogenetics in Japan gain a unique position in the world research community.

  2. Generic antibiotics in Japan.

    Fujimura, Shigeru; Watanabe, Akira

    2012-08-01

    Generic drugs have been used extensively in many developed countries, although their use in Japan has been limited. Generic drugs reduce drug expenses and thereby national medical expenditure. Because generic drugs provide advantages for both public administration and consumers, it is expected that they will be more widely used in the future. However, the diffusion rate of generic drugs in Japan is quite low compared with that of other developed countries. An investigation on generic drugs conducted by the Ministry of Health, Labour and Welfare in Japan revealed that 17.2 % of doctors and 37.2 % of patients had not used generic drugs. The major reasons for this low use rate included distrust of off-patent products and lower drug price margin compared with the brand name drug. The generic drugs available in the market include external drugs such as wet packs, antihypertensive agents, analgesics, anticancer drugs, and antibiotics. Among them, antibiotics are frequently used in cases of acute infectious diseases. When the treatment of these infections is delayed, the infection might be aggravated rapidly. The pharmacokinetics-pharmacodynamics (PK-PD) theory has been adopted in recent chemotherapy, and in many cases, the most appropriate dosage and administration of antibiotics are determined for individual patients considering renal function; high-dosage antibiotics are used preferably for a short duration. Therefore, a highly detailed antimicrobial agent is necessary. However, some of the generic antibiotics have less antibacterial potency or solubility than the brand name products. We showed that the potency of the generic products of vancomycin and teicoplanin is lower than that of the branded drugs by 14.6 % and 17.3 %, respectively. Furthermore, we confirmed that a generic meropenem drug for injection required about 82 s to solubilize in saline, whereas the brand product required only about 21 s. It was thought that the cause may be the difference in size of bulk

  3. Spent fuel management in Japan

    Japan has scarce energy resources and depends on foreign resources for 84% of its energy needs. Therefore, Japan has made efforts to utilize nuclear power as a key energy source since mid-1950's. Today, the nuclear energy produced from 49 nuclear power plants is responsible for about 31% of Japan's total electricity supply. The cumulative amount of spent fuel generated as of March 1995 was about 11,600 Mg U. Japan's policy of spent fuel management is to reprocess spent nuclear fuel and recycle recovered plutonium and uranium as nuclear fuel. The Tokai reprocessing plant continues stable operation keeping the annual treatment capacity or around 90 Mg U. A commercial reprocessing plant is under construction at Rokkasho, northern part of Japan. Although FBR is the principal reactor to use plutonium, LWR will be a major power source for some time and recycling of the fuel in LWRs will be prompted. (author). 3 figs

    The purpose of this special issue was to describe the cross-cultural differences in neuropsychology throughout the world. The current state of neuropsychology in Japan is discussed in this manuscript. Information on six topics, including (1) the history of Japanese neuropsychology, (2) licensure system, (3) job opportunities, (4) neuropsychological clinical services, (5) neuropsychological tests, and (6) neuropsychological research, was gathered via literature searches, official organization websites, and personal communication with clinical psychologists and other professionals in Japan. Neuropsychology reached Japan from the west in the late 1800s, a period of rapid political and social modernization. Professional associations were founded in the 1960s and 1970s and continued to grow. The need for neuropsychological assessment in Japan is growing; however, credential requirements for neuropsychologists have not yet been established. To practice clinical psychology in Japan, one must obtain a Master's degree and pass a licensure examination that is administered by a private professional foundation. Clinical psychologists often conduct neuropsychological tests; however, they have little training in neuropsychological assessment. While many western neuropsychological tests have been translated into Japanese and are used in clinical settings, the majority of translated tests have not been standardized and their psychometric properties remain poorly understood. Standardization and development of normative data in Japan is warranted. Given that needs for neuropsychological services are increasing, it is essential for clinical psychologists in Japan to improve their skills in neuropsychological evaluations. Japanese graduate schools must work to establish neuropsychology programs to educate and train clinical neuropsychologists.

    In many areas, the word most often used to describe Japanese policy is open-quotes enigma.close quotes In some ways, Japan's record on environmental policy also has elements of mystery and contradiction. On the one hand, Japan's history and culture often are associated with a reverence for nature. Indeed, Japan does lead the world in certain environmental areas, such as reduction of conventional air pollutants and compensation of air pollution victims. On the other hand, Japan has been widely criticized for its poor record in preserving its domestic environment, contribution to tropical deforestation, and unwillingness to protect endangered species. Today, the international community clamors for Japan to take its share of responsibility, as an economic superpower, for the global environment. To secure its place in world affairs, Japan slowly has begun to respond to this pressure on issues ranging from ivory importation to reduction of CFC emissions. There is some hope that the government's particular willingness to address global warming may be a sign of significant changes to come in Japanese environmental policy. However, international pressure remains on the many environmental issues Japan has yet to resolve, including tropical deforestation and financing of Third World development projects that harm the environment. Japan's environmental policy is most effective when government and industry cooperate to find technical solutions to environmental problems. Although in recent years Japan's energy consumption has risen sharply, the Japanese have developed numerous technologies to reduce pollution and increase economic growth by improving energy efficiency. It is in these technologies that Japan has made the greatest strides and has the most to offer the global environment

  7. Photovoltaic research and development in Japan

    1983-01-01

    The status of the Japanese photovoltaic (PV) R&D activities was surveyed through literature searches, private communications, and site visits in 1982. The results show that the Japanese photovoltaic technology is maturing rapidly, consistent with the steady government funding under the Sunshine Project. Two main thrusts of the Project are: (1) completion of the solar panel production pilot plants using cast ingot and sheet silicon materials, and (2) development of large area amorphous silicon solar cells with acceptable efficiency (10 to 12%). An experimental automated solar panel production plant rated at 500 kW/yr is currently under construction for the Sunshine Project for completion in March 1983. Efficiencies demonstrated by experimental large are amorphous silicon solar cells are approaching 8%. Small area amorphous silicon solar cells are, however, currently being mass produced and marketed by several companies at an equivalent annual rate of 2 MW/yr for consumer electronic applications. There is no evidence of an immediate move by the Japanese PV industry to enter extensively into the photovoltaic power market, domestic or otherwise. However, the photovoltaic technology itself could become ready for such an entry in the very near future, especially by making use of advanced process automation technologies.

    ‘religion’ is not a subject in schools. So, how do the Japanese go about the business of teaching values and morality? Using the Japanese example, this volume looks at moral education from the basic point of view of universal and common human values, with due attention given to culture-specific traits...... in the legal frame work (the Fundamental Law on Education was revised in 2006) and the ministerial guidelines and policies (new curriculum guidelines have been issued after the law change, and new proposals for strengthening the position of moral education come on a regular basis) have reflected the increased......What is a ‘good’ person and how do we educate ‘good’ persons? This question of morality is central to any society and its government and educational system including the Japanese. In many societies it has been customary to teach about morality from a religious standpoint, but not so in Japan, where...

    Slowly winding its way down, Typhoon Chataan had dropped to tropical storm status by Thursday, July 11, 2002, when this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) was captured. In the image, the storm is located off the east coast of central Japan in the Pacific Ocean. The storm is much less organized than it was in the previous day's image. Through a gap in the clouds to the southwest of the storm's eye, Tokyo can be seen as a grayish cluster of pixels surrounding a small bay or inlet that protrudes into the island of Honshu.

    Economic scale of radiation application in the field of industry, agriculture and medicine in Japan in 1997 was investigated to compare its economic impacts with that of nuclear energy industry. Total production value of radiation application accounted for 54% of nuclear industry including nuclear energy industry and radiation applications in three fields above. Industrial radiation applications were further divided into five groups, namely nondestructive test, RI instruments, radiation facilities, radiation processing and ion beam processing. More than 70% of the total production value was brought about by ion beam processing for use with IC and semiconductors. Future economic prospect of radiation processing of polymers, for example cross-linking, EB curing, graft polymerization and degradation, is reviewed. Particular attention was paid to radiation vulcanization of natural rubber latex and also to degradation of natural polymers. (S. Ohno)

  13. SCWR Concepts in Japan

    Two SCWR concepts are being developed in Japan, one corresponding to the thermal spectrum reactor and the other to the fast spectrum reactor. Yamada et al. described the thermal-spectrum reactor concept referred to as the Japan SCWR (or JSCWR). This concept was developed under the financial support of the Ministry of Economy, Trade and Industry (METI). The basic philosophy of the JSCWR development is to utilize proven light water reactor and supercritical fossil-fired power plant technologies as much as possible to minimize the R&D cost, time and risks. Therefore, the JSCWR is designed as a thermal neutron spectrum reactor using light water as moderator and reactor coolant. The JSCWR plant consists of a pressure-vessel type, once-through reactor and a direct Rankine cycle system. Reactor coolant fed through inlet nozzles is heated up in the core and flows through outlet nozzles with no recirculation in the vessel. Other options to the JSCWR core design are being investigated at the University of Tokyo. The electric output of the JSCWR is assumed to range from 600 MWe to 1700 MWe class to fulfill user’s requirements as much as possible. In this section, the reference value is selected to 1725 MWe, which corresponds to a reactor thermal output of 4039 MWth. Nakatsuka et al. described the core design for the fast-spectrum reactor, which is based on a similar plant system compared to that of the thermal-spectrum reactor. The fast-spectrum reactor, however, would produce higher power rating than the thermal-spectrum one of the same reactor pressure-vessel size. Since the fast-spectrum reactor does not require the moderator, its unit capital cost would be lower than the thermal-spectrum reactor.

    We conducted multi-directional language development tests as a part of the Research on Sensory and Communicative Disorders (RSVD) in Japan. This report discusses findings as well as factors that led to better results in children with severe-profound hearing loss. We evaluated multiple language development tests in 33 Japanese children with cochlear implants (32 patients) and hearing aid (1 patient), including 1) Test for question and answer interaction development, 2) Word fluency test, 3) Japanese version of the Peabody picture vocabulary test-revised, 4) The standardized comprehension test of abstract words, 5) The screening test of reading and writing for Japanese primary school children, 6) The syntactic processing test of aphasia, 7) Criterion-referenced testing (CRT) for Japanese language and mathematics, 8) Pervasive development disorders ASJ rating scales, and 9) Raven's colored progressive matrices. Furthermore, we investigated the factors believed to account for the better performances in these tests. The first group, group A, consisted of 14 children with higher scores in all tests than the national average for children with hearing difficulty. The second group, group B, included 19 children that scored below the national average in any of the tests. Overall, the results show that 76.2% of the scores obtained by the children in these tests exceeded the national average scores of children with hearing difficulty. The children who finished above average on all tests had undergone a longer period of regular habilitation in our rehabilitation center, had their implants earlier in life, were exposed to more auditory verbal/oral communication in their education at affiliated institutions, and were more likely to have been integrated in a regular kindergarten before moving on to elementary school. In this study, we suggest that taking the above four factors into consideration will have an affect on the language development of children with severe

    Fifty years ago, a week-long school for physicists took place in Saint Cergue, in the Jura mountains not far from CERN. Its focus was on using emulsion techniques, but its legacy was much more far reaching. Last week I was in Fukuoka, Japan, on the last day of a direct descendent – the first Asia–Europe–Pacific School of High-Energy Physics (AEPSHEP).   That first small school in 1962 was the precursor to the annual European Schools of High-Energy Physics, which are organised jointly by CERN and the Joint Institute for Nuclear Research (JINR) in countries that are a member state of either (or both) of the organisations. They led in turn to the CERN–Latin-American School of High-Energy Physics, first held in Brazil in 2001. The aim of these schools is not only to give young particle physicists the opportunity to learn from leading experts in the field, but also to nurture from the start communication among researchers from different regions.

    1998-01-01

    In Japan 52 commercial nuclear power units are now operated, and the total power generation capacity is about 45 GWe. The cumulative amount of spent fuel arising is about 13,500 tU as of March 1997. Spent fuel is reprocessed, and recovered nuclear materials are to be recycled in LWRs and FBRs. In February 1997 short-term policy measures were announced by the Atomic Energy Commission, which addressed promotion of reprocessing programme in Rokkasho, plutonium utilization in LWRs, spent fuel management, backend measures and FBR development. With regard to the spent fuel management, the policy measures included expansion of spent fuel storage capacity at reactor sites and a study on spent fuel storage away from reactor sites, considering the increasing amount of spent fuel arising. Research and development on spent fuel storage has been carried out, particularly on dry storage technology. Fundamental studies are also conducted to implement the burnup credit into the criticality safety design of storage and transportation casks. Rokkasho reprocessing plant is being constructed towards its commencement in 2003, and Pu utilization in LWRs will be started in 1999. Research and development of future recycling technology are also continued for the establishment of nuclear fuel cycle based on FBRs and LWRs. (author)

    1989-01-01

    Data on the development level of nuclear power in Japan as of 1988 beginning are presented. Total registed electric power of 36 nuclear power units under operation constituted 28046 MW. 13 power units with 12268 MW total power are under construction. In 1987 188.4 TWH electric power was generated at the Japanese NPPs, it constituted 31.7% of total electric power generation. About 360 bil. yens were assigned from the state budget to further development of nuclear power engineering. Efforts to create the improved BWR type reactor, as well as, scientific and research efforts on the development of fast breeder reactors, improvement of uranium enrichment and radioactive waste storage are carried out. It is expected that share of nuclear power in electric power generation in Japan will reach 40% to the beginning of the 21-th century

    1980-01-01

    Japan depends 88% of energy resources and 99.8% of petroleum on imports. The solution of energy problems is now made internationally. As the means for Japan, there are the substitution of other resources for petroleum and its promotion. However, this involves the considerable funds for the development and utilization, which must be borne by the people in the form of tax. For governmental financing, a special account must be set up for the particular purpose. In the research and development of new energy resources, new institution is required. The following matters are described: petroleum shortage coming even in 1980s, the international need of substitute energy development, the need for establishing measures for substitute energy resources, acquisition of the funds, special-account governmental financing, and an institute of new energy development.

    International Nuclear Information System (INIS)

    1998-12-01

    The partnership between the Cogema group and Japan in the domain of fuel cycle started about 20 years ago and the 10 Japanese nuclear operators are all clients of the Cogema group. The 1997 turnover realized with Japan reached 3.6 billions of francs (11% of the total turnover of the group). This short paper presents briefly the nuclear program of Japan (nuclear park, spent fuels reprocessing-recycling strategy) and the contracts between Cogema and the Japanese nuclear operators (natural uranium, uranium conversion and enrichment, spent fuel reprocessing, plutonium recycle and MOX fuel production markets).

    Nuclear forensics is the analysis of intercepted illicit nuclear or radioactive material and any associated material to provide evidence for nuclear attribution by determining origin, history, transit routes and purpose involving such material. Nuclear forensics activities include sampling of the illicit material, analysis of the samples and evaluation of the attribution by comparing the analysed data with database or numerical simulation. Because the nuclear forensics methodologies provide hints of the origin of the nuclear materials used in illegal dealings or nuclear terrorism, it contributes to identify and indict offenders, hence to enhance deterrent effect against such terrorism. Worldwide network on nuclear forensics can lead to strengthening global nuclear security regime. In the ESARDA Symposium 2015, the results of research and development of fundamental nuclear forensics technologies performed in Japan Atomic Energy Agency during the term of 2011-2013 were reported, namely (1) technique to analyse isotopic composition of nuclear material, (2) technique to identify the impurities contained in the material, (3) technique to determine the age of the purified material by measuring the isotopic ratio of daughter thorium to parent uranium, (4) technique to make image data by observing particle shapes with electron microscope, and (5) prototype nuclear forensics library for comparison of the analysed data with database in order to evaluate its evidence such as origin and history. Japan’s capability on nuclear forensics and effective international cooperation are also mentioned for contribution to the international nuclear forensics community.

  3. Diagnostics in Japan's microgravity experiments

    1995-01-01

    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.

  4. Outage planning in Japan

    1997-01-01

    Nuclear plant operators in Japan are constrained to keep refuelling and maintenance outages to a minimum by the regulation limiting operating cycles to no longer than 13 months. Outage planning by two contrasting operators is described. Hokkaido Electric, which operates only one plant, Tomari, with two PWRs, plans to reduce outage time from the present 65 days in two stages. Detailed review of previous outage schedules has shown that a reduction to 59 days should be achievable by careful planning without any fundamental changes. The second reduction to 49 days will require such measures as relaxing water purity standards, rescheduling fuel unloading and loading shifts and speeding up eddy current testing of primary equipment by using steam generator nozzle dams. Kansai Electric, operating 11 PWRs at three plants, has scope for reducing outages at all of its units using a range of measures. Steam generator replacement in the seven oldest reactors, completed in July 1997, is by far the most significant of these and is expected to save 64 days repair time in a previous average outage time of 131 days.

    1994-01-01

    The energy situation in Japan is briefly outlined. Vulnerability in energy structure of the country is shown by a comparison of primary energy supply patterns of Japan and Western countries. Japan's energy policy consists in reducing dependence on oil, promoting efficient use of energy and increasing use of non-fossil fuels. Nuclear power is a core of alternative energy for petroleum because of stable supply of nuclear fuel, low detrimental emissions and less dependence on the fuel. A short historical review of nuclear power development in Japan is presented. Some future issues as development of entire nuclear fuel cycle, social acceptance, reactor safety and nuclear power economics are also discussed. 6 figs. (R.T.)

    The purpose of the study was to report the prevalence of trauma exposure and PTSD, conditional risk of PTSD associated with each trauma exposure in the community population in Japan. An interview survey was conducted of a random sample of adult residents in 11 communities of Japan. Among 4134 respondents (response rate, 55%), data from those who completed the part 2 interview (n = 1682) were analyzed with a weight for this subsample. Lifetime experiences of 27 trauma events and PTSD were assessed using the WHO-Composite International Diagnostic Interview version 3.0. Sixty percent of the part 2 sample reported exposure to at least one lifetime traumatic event. Lifetime and 12-month PTSD prevalences were 1.3% and 0.7%, respectively. Percentage of all months lived with PTSD in the population was predominantly accounted for by physical/sexual assaults and having a child with serious illness, and unexpected death of loved one. Ten percent of respondents reported “private events”, for which respondents did not have to describe the content, which accounted for 19% of months with PTSD. The lower prevalence of PTSD in Japan seems attributable to lower conditional risks of PTSD following these events, as well as different distributions of the events. The greater impact of events that occurred to loved ones rather than to oneself and “private events” on PTSD in Japan warrants further research of cross-cultural assessment of trauma exposure and cultural heterogeneity in the trauma-PTSD relationship.

    The goal of monetary policy as conducted by the Bank of Japan is to contribute to the sound development of the national economy through the pursuit of price stability. The objective of price stability, however, is not precisely defined as it has been for other central banks. Following the implementation of the new Bank of Japan Law in 1998, the monetary policy framework is characterized by central bank independence, the primacy of the price stability objective, instrument independence, and po...

  10. Results of operation of BWRs in Japan

    1987-01-01

    It is considered that the development of BWR plants in Japan has been advanced relatively smoothly though sometimes there were complications. As of the end of fiscal year 1986, the BWR plants in operation were 16, and the total power output amounted to 12,917 MW, which was equivalent to 8 % of 153 GW of the total power source facilities in Japan. Reflecting the excellent operational result of BWR plants, the generated electric power in fiscal year 1986 reached 85.9 TWh and about 15 % of the total, exceeding hydroelectric power. This means that about 18 million tons of petroleum import was reduced. At the initial stage, BWR plants suffered the stress corrosion cracking of stainless steel pipings in the reactor primary system. This trouble was successfully solved by the efforts of the government, electric power companies, plant manufacturers and research institutes. In fiscal year 1983, the capacity factor of all BWR plants in Japan recovered to more than 70 %, and in fiscal year 1986, it has reached 75.9 %. In order to improve the capacity factor further, it is necessary to prevent troubles by the development of diagnostic techniques and preventive maintenance, and to shorten regular inspection period. The change of accidents and troubles, the measures to reduce regular inspection period, the reduction of radiation exposure, and the reduction of wastes are reported. (Kako, I.)

    In a global environment, education for healthcare professionals should include cultivating human resources who have the necessary skills to work in an international arena. This article will review the current status of English education for dental healthcare professionals in Japan. After conducting a literature search using the keywords: English education, Japan, and dental, only a few studies were found that investigated and proposed suggestions for dental professional English education. Even so, these were still in the early stages with outcomes yet to be fully evaluated. Even though English is thought indispensable for global professionals, and that increasing chances for communication skills is necessary, little attention has been addressed to English education for dental professionals or the implementation of such education in the Japanese undergraduate dental curricula. With the current reality of field expansion in dentistry, the need for not only improved English communication skills for Japanese dentists, but also the acquisition of essential expertise, psychomotor, teambuilding, critical thinking, and creative thinking skills in English as well as Japanese, is a definite probability. In order to reach this level of knowledge, further efforts and research would be necessary for the advancement and development of dental professional English education in Japan.

    Traditional Japanese dietary culture might be a factor contributing to the high life expectancy in Japan. As little is known about what constitutes traditional and modern eating in Japan, the aims of the current study were to (1) comprehensively compile and systematize the various facets of traditional and modern eating; and (2) investigate whether these facets also apply to traditional and modern eating in Japan. In Study 1, an extensive international literature review was performed. Forty-five facets of traditional and modern eating were compiled and systematized into the dimensions of what and how people eat, and into eleven separate subdimensions. In Study 2, 340 adults from Japan answered a questionnaire. Results showed that traditional and modern eating in Japan is reflected in both what and how people eat. Within these two dimensions, ten subdimensions were found: the ingredients, processing, temporal origin, spatial origin, and variety of consumed foods, as well as temporal, spatial, and social aspects, appreciation, and concerns when eating. This study provides a broad compilation of facets of traditional and modern eating in Japan. Future research should investigate how these facets are related to life expectancy and health.

    Since 2010, International Atomic Energy Agency (IAEA) has held the 'Nuclear Energy Management School' so-called 'IAEA-NEM' to develop future leaders who plan and manage nuclear energy utilization in their county. Since 2012, Japan Atomic Energy Agency (JAEA) together with the Japan Nuclear Human Resource Development Network (JN-HRD Net), the University of Tokyo (UT), the Japan Atomic Industrial Forum (JAIF) and JAIF International Cooperation Center (JICC) have cohosted the NEM school in Japan in cooperation with IAEA. Since then, the school has been held every year, with the school in 2016 marking the fifth. In the 2016 NEM school, Japanese nuclear energy technology and experience, such as lessons learned from the Fukushima Daiichi Nuclear Power Station accident, were provided by not only lectures by IAEA experts, but also lectures by Japanese experts and leaders in order to offer a unique opportunity for the participants from other countries to learn about particular cases in Japan. Opportunities to visit a variety of nuclear facilities were offered for the participants in the form of technical tours in Fukui and Kobe. Through the school, we contributed to the internationalization of Japanese young nuclear professionals, development of nuclear human resource of other countries including nuclear newcomers, and enhanced cooperative relationship between IAEA and Japan. Additionally, collaborative relationship with JN-HRD Net was strengthened solidly through the integrated cooperation among ministries, universities, manufacturers and research organizations across the county by holding the school in Japan. In this report, findings obtained during the preparatory work and the school period were reported in order to make a valuable contribution towards effectively and efficiently conducting future international nuclear human resource development activities in Japan.

    1990-01-01

    The Japanese movement against nuclear energy reached a climax in its upsurge in 1988 two years after the Chernobyl accident. At the outset of that year, this trend was triggered by the government acknowledgement that the Tokyo market was open to foods contaminated by the fallout from Chernobyl. Anti-nuclear activists played an agitating role and many housewives were persuaded to join them. Among many public opinion surveys conducted at that time by newspapers and broadcasting networks, I would like to give you some figures of results from the poll carried out by NHK: Sixty percent of respondents said that nuclear power 'should be promoted', either 'vigorously' 7 or 'carefully' 53%). Sixty-six percent doubted the 'safety of nuclear power', describing it as either 'very dangerous' 20%) or 'rather dangerous' (46%). Only 27% said it was 'safe'. In other words, those who acknowledged the need for nuclear power were almost equal in number with those who found it dangerous. What should these figures be taken to mean? I would take note of the fact that nearly two-thirds of valid responses were in favor of nuclear power even at the time when public opinion reacted most strongly to the impact of the Chernobyl accident. This apparently indicates that the majority of the Japanese people are of the opinion that they would 'promote nuclear power though it is dangerous' or that they would 'promote it, but with the understanding that it is dangerous'. But the anti-nuclear movement is continuing. It remains a headache for both the government and the electric utilities. But we can regard the anti-nuclear movement in Japan as not so serious as that faced by other industrial nations

    Four research reactors are currently licensed for medical application in Japan. As of July 1995, approximately 210 clinical irradiations using these research reactors have been done for brain and skin tumors as shown. The number of chief medical doctors certified by the Government is eleven so far. Among them, eight doctors have already treated tumor patients using the Kyoto University Reactor (KUR, 5MW). Recently in USA clinical trials have been restarted using epithermal neutrons at MIT and BNL. In this paper, the experience of clinical trials of boron neutron capture therapy (BNCT) which have been performed in Japan, mainly physics studies, are reviewed, and current studies are also introduced
