    This report relates to the designing of functional materials that decompose in response to various signals. A derivative of {alpha}-bromomethylstyrene is caused to act on the living anions of {alpha}-methylstyrene for the synthesis of a pyrolytic polymer having unsaturated groups at its terminals. The terminal double combinations of this polymer split under the influence of heat, acid, or base for depolymerization which is quantative, and the decomposition temperature may be controlled by replacing terminal phenylallylic groups with methyl groups or phloro-groups. Furthermore, a novel polythyramine polymer is synthesized with its principal chain constituted of NCH2CH2Si, the principal chain easy to disintegrate when exposed to an electron beam. The polymer is signal-responsive and may be patterned by use of an electron beam. As a temperature-responsive polymer with the hydrolytic feature controlled, poly(thyroxy ethylene glycol) is obtained from a derivative of diaminosiloxane and oligo-oxyethylene. This is a high-mobility, temperature-responsive material whose hydrolysis may be controlled. 3 refs., 2 figs.

    With relation to the coal of the Philippines, where the expansion of the use of coal as a substitute for petroleum/plant fuel is aimed at, the paper grasped the situation of coal production/development, the trend of coal import and domestic distribution, the coal utilization trend, and environmental problems, and analyzed the situation of coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to draw up a master plan for the introduction of the environmentally-friendly coal utilization system. As to the use of environmentally-friendly coal technology which should be adopted to the coal mining industry and commercial/residential sector, cited are the introduction of coal preparation technology and power transmission technology, and the development/spread of briquette as a firewood substituting fuel. In the electric power sector, the problem is the treatment of ash after combustion and the effective use. Relating to the treatment of flue gas, there is no installation at all of desulfurization facilities and denitrification facilities. In the cement industry sector, they wish to return fuel from heavy oil to coal. For it, it is necessary to study dust preventive measures. In the other sectors, coal hasn`t been used very much. An increase in coal demand is not expected also in the future, and big problems concerning coal haven`t occurred. 42 figs., 64 tabs.

    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

    The paper investigated and studied the present situation and future trend of coal utilization and distribution in Thailand, and the present situation of environmental effects and the measures taken for environmental protection. Around 2010, coal will probably be produced only at EGAT`s Mae Moh (MM) coal mine. Demand for overseas coal is expected to be 40-50 million tons in 2011, and preparation of the coal center becomes a subject. For general industry use coal, pretreatment such as coal preparation, coal blending and briquetting is needed, considering coal quality, usage, transport distance and environmental effects. Brown coal of MM coal mine is a lignite with high sulfur, high ash content and low heating value. Wide spread of its use can be expected if upgrading is possible such as desulfurization, deashing, increasing heating value. In the electric power generation field, the absorber was installed at the existing boiler of the mine-mouth generating plant to conduct a verification test on high grade desulfurization of ultra-high sulfur lignite. In the industry field, the circulating fluidized bed boiler was adopted. In the residential/commercial field, introduction of briquette was proposed. 80 refs., 84 tabs.

    The paper surveyed the present situation and future trend of economy, energy supply/demand, coal production/distribution/utilization and the environmental effects in Thailand. The survey on the coal utilization and its environmental effects was partially requested of the environmental research institute in Thailand. The amount of coal utilization in Thailand rapidly increased to nearly four times as large as that ten years ago mainly in terms of domestic lignite under the government`s policy on expansion of the domestic energy use. However, most of this domestic lignite is low-grade coal with low calories and high sulfur content, and the use of it was rapidly increased mostly in power generation sector without no adequate environmental measures taken. This caused an environmental problem on air pollution due to sulfur oxides at Mae Moh power plant in the north several years ago, and the damages to the regional residents, etc. were given much publicity by journalism and developed the social problem. Accordingly, Thai people are now critical of the coal resource exploration and the coal use expansion. Under the circumstances, the Ministry of Industry and the energy related ministries/offices are obliged to review their development/promotion plans. 84 figs., 99 tabs.

    Grasping the present situation of coal utilization technology in the Philippines, the paper proposed a feasibility study of introduction of the environmentally friendly type coal utilization system which seems to be needed in the future. (1) Introduction of the environmentally friendly type coal utilization system in the electric power generation sector: there are only four full-scale running coal thermal power plants in the Philippines. In the future, several coal thermal plants are planned to be constructed by 2005, but for the new installation, it is desirable to adopt fluidized bed boilers with wide application to coal kinds. In case of 0.3-1.0 million MW class plants, it is planned to adopt high grade import coals, and it will be natural to fire pulverized coal. For the processing of flue gas, it is a must to install desulfurization facilities and smoke/soot removal devices. (2) Utilization/development of domestic low grade coals: at the mine-mouth generating plant, it is necessary to investigate the economically minable amount of coal, confirm productivity, survey coal quality, etc., and select boiler. As to coal briquetting technology, it is necessary to examine coal quality for tests and make a thorough study of what technology is most suitable. 50 figs., 78 tabs.

    A survey was made in India which is a coal producing/consuming country following China in Asia and where coal is used for about 60% of the primary commercial energy. The survey was conducted on coal production/distribution/utilization and environmental issues, aiming at studying feasibility of introducing the environmentally friendly coal utilization system into every industry including the residential/commercial one, and at implementing a comprehensive master plan including Japan`s international cooperation. Total power source facilities in fiscal 1995 are 83.3 million kW, 64% of which are coal thermal power facilities and generated 260 TWh, 69% of the total output energy. Main commercial energy sources are coal, oil and natural gas, and oil is self-sufficient. The survey this time did not examine very well the actual state of the environmental pollution problem caused by the coal utilization. Indian coal is high in ash content but low in sulfur content, and therefore, SOx polluting air has not been a very important problem so far, but soot/smoke is almost the problem. Further, ash treatment after combustion at boilers, etc. is expected to be a big problem in the future. 49 figs., 88 tabs.

    Studies are conducted for the development of now-unused kinds of fossil carbon resources, such as low rank coal and heavy gravity crude oil, into higher-value liquid fuel. In the preliminary treatment process, the fossil carbon resources are dried by use of supercritical carbon dioxide, when it is found that the resources are disintegrated and water is desorbed. In a low rank coal liquefaction process using the NiMo/KB (Kefjen Black) catalyst, more than 60% is converted into oil, which rate is improved by use of the dual-temperature liquefaction process. This catalyst may be recovered by separation utilizing specific gravity difference. As a low temperature gasification catalyst, the alkaline carbonate-carried carbon catalyst is very quick at the initial stage of reaction. The perovskite-carried alkaline carbonate catalyst is high in carbon oxidizing/activating efficiency at low temperatures. The silica film deposited on an alumina-coated support tube is excellent in selectivity and speed as a hydrogen separating film, and a carbonized polyimide film as a carbon dioxide separating film. For the supercritical phase adsorption/separation of chemicals not to be distilled easily, the NaY-type zeolite functions effectively. Pd/ZrO2 serving as a carbon monoxide conversion catalyst enables the recovery of more MeOH when Pd grains are smaller in diameter.

    For the current treatment of disused cars, valuable materials are recovered after scrapping them, and residual car shredder dust (CSD) is reclaimed. The load of land reclamation can be reduced by decreasing its volume and weight through incineration of combustibles in the CSD. Thermal energy obtained during the incineration can be converted into electric power. CSD-fired power generation plant has been planned, by which the obtained power is sold to electric power companies. It was assumed that the power generation plant is constructed at a certain city of Ibaraki Prefecture. Two cases of plant scales, i.e., 200 t/d and 400 t/d, were investigated by considering the collecting quantity of CSD fuel and the area of sites. The CSD fuel with 4,500 kcal/kg of lower calorific value contains rather high contents of chlorine and sulfur, which are around 3% and 1.6%, respectively. Therefore, the system should have measures, such as the exhaust gas treatment, dioxin treatment, and prevention of corrosion for high efficiency. It was concluded that about 300 t/d scale plant provides a feasibility. 27 refs., 21 tabs.

    To suppress the emission of environmental pollutants from coal utilization in Indonesia and to contribute to stable security of Japan`s energy, demonstration of clean coal technology and consolidation of diffusion base to be introduced into Indonesia have been promoted. Briquette production plant installed in the Tanjun Enim Coal Mine was examined and guided. Two kinds of high-volatile subbituminous coals are used as raw materials. Semi-cokes with volatile matter of 20% are prepared through fluidized carbonization at 480 degC. Hydrated lime or clay and binder are added to the semi-cokes, to manufacture ball briquettes by molding at room temperature. These are forcedly dried in the continuous drying furnace. In the design, 5 ton ball briquettes can be produced for an hour. Operation time is between 8 and 15 hours in a single shift. Products completely without smoke and smell can be obtained. Combustion performance of the products is remarkably superior to that of conventional products. The operation techniques of carbonization and molding processes were actively guided. To produce briquettes with further high quality, it was suggested that blending ratios and coal properties should be investigated. Inspection method for each apparatus was also guided. There was no abrasion. 13 figs., 2 tabs.

    Surveys and discussions were given on business feasibility of a wide area RDF power generation system in the Kishu and Kumano living area. The discussions dealt with as wide area as transcending prefectural borders and including the southern parts of Mie and Nara Prefectures with the city of Shingu as the central part. Wastes generation amount is estimated to be about 70,000 tons at the present as wastes that can be turned into RDF, and to be decreased to 67,000 tons in 2018. The manufactured RDF has calorific power of 3500 to 4500 kcal/kg, two to three times greater than that of wastes. The RDF manufacturing facilities installed in cities, towns and villages have capacity of 30 to 50 tons a day, with that in the city of Shingu being the largest at about 78 tons a day. Transportation can be implemented most efficiently when road transportation is used. The RDF power generation system will consist of a fluid bed furnace, a plasma type ash melting furnace, and a bag filter plus activated carbon absorbing tower. The RDF manufacturing cost will be 27,900 yen per ton of wastes in the case of the city of Shingu. In terms of business profitability, the RDF power generation must find sources to pay 21,400 yen per ton of RDF even if the power sale revenue is considered. (NEDO)

    This paper describes the discussion report for fiscal 1998 on the CMG (coal methane gas) recovery and utilization project to be implemented from fiscal 1998 through fiscal 2002 at Tiefa Mining Bureau of Liaoning Province in China. The Daixing mine was selected as the survey object. The introduced technologies and facilities include test drilling for degassing (medium measure horizontal degassing of 300-m class), induction from degassing holes, fly ash sealing, sealed gas degassing, surveillance and control technologies and facilities. The recovered gas is to be supplied to the cities of Tiefa and Tieling as town gas, for which compressed gas feeding and controlling technologies and facilities will be introduced. This paper lists the gush-out quantity (1,000 Nm{sup 3}), the recovery quantity (1,000 Nm{sup 3}), the recovered gas concentration (%), the utilization quantity (1,000 Nm{sup 3}), and the utilization rate (%). The figures for the respective items before and after the implementation are 128366, 32949, 44.5, 7000, 5, 123500, 43890, 49.1, 39826, and 32. The quantity of gas gushing out at facings decreases in association with increase in the recovered gas quantity, whereas the gas concentration at facings in the Daixing mine in 2003 is estimated to decrease to 0.1%, contributing to safe mining operation. The test drilling for medium measure horizontal degassing expands the degassing assured scope per one test drilling seat, and can reduce the total test drilling length and construction amount.

    High efficiency power generation, which is useful for promoting the environment-friendly type energy and coordinated community, is investigated by combining a steam turbine power generation system using the PS-RDF (paper sludge-refuse derived fuel) and a gas turbine (GT) combined cycle. Industrialization plan for processing PS in low cost has been made to ensure the profitability by participating the wholesale power supply under the law of electric power industry. This combined system is similar to the so-called super power generation using municipal garbage, but the lower temperature of steam from GT waste heat boilers (WHB) is super-heated by the flue gas from RDF boiler, which is called advanced power generation system (A.S.S.). The total power generation capacity is 149,000 kW, which consists of three 35,000 kW units of GT and one 44,000 kW unit of steam turbine. When comparing the combined system (A.S.S.) and usual one with the independent installation of the RDF steam power generation system and a GT combined cycle, the A.S.S. provides the repowering efficiency of 7,600 kW output with exactly the same quantity of fuel input as usual one. 71 figs., 31 tabs.

    To verify the clean coal technology to be diffused in China and consolidate its diffusion basis, demonstration project of circulating fluidized bed boiler was conducted through the cooperation with China which is positive in its introduction. This report describes its characteristics. Coal and limestone are supplied in a lower part of combustion chamber, and are mixed with circulating ash by fluidized air for combustion. Densely fluidized bed the same as the bubbling fluidized bed is formed in the lower part of combustion chamber, which provides excellent stability in ignition and combustion. Particles including ash, char and limestone formed during the combustion are discharged into the cyclone through the convection heat transfer part at the outlet of combustion chamber with the combustion gas flow. Since the gas temperature is lowered to 400 to 500degC at the convection heat transfer part, troubles of the ash circulating system can be prevented. The combustion gas separated from ash at the cyclone is discharged through the heat exchanger and precipitator, and the collected ash is returned to the lower part of combustion chamber. In FY 1997, design, fabrication, procurement/inspection, field survey/meeting, survey of visitors/meeting, and education were carried out. 4 figs., 4 tabs.

    The refuse-derived fuel (RDF) has been holding public attention not only as the energy resource of stable high calorific value for local energy development, but also as the effective method for waste treatment. As one of the effective utilization methods for waste treatment, this investigation was conducted to industrialize and establish the RDF power generation system, in which power generation and ash treatment are integrated in Tochigi Prefecture which is located inland. The base supply type was adopted as a way of operation from the menu of the electricity wholesale project of Tokyo Electric Power Co. and its rate of operation is 80 percent a year. Then, the fluidized bed combustion method, a dry exhaust gas treatment method, and continuous electric melting furnaces were decided as the RDF power generation system. According to this system, it is possible to obtain 26 percent gross thermal efficiency by conventional generation facilities. It was estimated that the expenses reduction for 15 years will be 17.6 billion yen compared with the ordinary combustion system. Also, the following effects can be expected; the reduction of CO2 emission, improvement of energy efficiency, and the extension of life of landfills capacity. 36 figs., 51 tabs.

    For the follow-up project, to promote the diffusion of results of the clean coal technology (CCT) model projects, experts of circulating fluidized bed boilers were dispatched, to guide and advise for the operation of facilities introduced in these projects. The purpose of these projects is to diffuse the CCTs, and to support the promotion of environmental measures. Some guidance and advice about operation processes, data processing, operation regulation, maintenance, and boiler maintenance works were provided to the Ministry of Energy and Electric Power Corporation of the Philippines. Semirara, Malangas, and Samar coals in the Philippines were used for the tests. The boiler facilities could be operated by Philippine operators themselves. Based on the guidance and advice about operation processes, combustion tests using various Philippine coals were also planned and conducted by themselves. The maintenance techniques were transferred to Philippine operators through the inspection, repair and advice. The Philippine side understood the technologies well, and the circulating fluidized bed boiler technology was independently educated in the Philippines. 23 figs., 16 tabs.

    Investigations and discussions were given on electric power generation business using as fuel the industrial wastes RDF composed of waste plastics having been manufactured in four blocks in Fukui Prefecture and sewage sludge. The investigations were carried out on estimation of quantity of the industrial wastes available in Fukui Prefecture and quantity of the industrial waste RDF supply, an optimal system for industrial waste RDF power generation, evaluation on economic effects, and environment improving effects. The result of the investigations revealed that the industrial waste RDF can be assured at 80 tons a day, which can make the power generation capacity 5000 kW. The industrial waste RDF manufacturing system adopts a chain type striking, crushing and drying equipment and a fluid bed combustion system. The ash melting system is a multi-phase alternating current system. This system is expected of enhancing the energy saving effect and the CO2 emission reducing effect. Economic effects were discussed on the industrial waste RDF manufacturing business and power generation business both on independent basis and continuous basis. Either case would require industrial waste RDF receiving fee. However, it was confirmed that the business can be realized on the continuous basis. (NEDO)

    In the manufacturing process of semiconductors and in the high tech industry, cleaning is indispensable. At present, when regulation of the use of CFC which used to be much used has been decided on, the conversion to the use of substitutes for CFC cleaning is urgently needed. Transfer to cleaning by water/alcohol/hydrocarbon has been proceeded with, but there are a lot of problems. Out of the development of the cleaning method using supercritical fluid, the paper described the fiscal 1997 result. As to enhancement of efficiency and decrease in size of equipment, a cleaning experiment by high pressure CO2 around the critical point was conducted by integrating nozzle, ultrasonic generator and cavitation generator and adding solvent circulating system. Multi-purpose and energy saving of the equipment were also studied. To establish an analysis method for the cleaning degree, the contaminated component film of trace organic matter with a specified thickness was formed on the silicon wafer, and using the Fourier transform ultrared spectroscopy, a method to determine the film thickness was studied. For the function evaluation for precision machine parts and determination of optimum cleaning conditions, the cleaning/degreasing process of valves were compared with the conventional method. For the product manufacturing, the paper investigated and prepared the data in Japan and from abroad. 55 refs., 79 figs., 18 tabs.

    This paper focuses on application of the recent biotechnology and introduces its new trends. What has triggered the boom in the application is when the technology has been applied to medicines in the 1970's. Beginning with insulin and interferon, various fibrinolytic agents including tPA and monoclonals have been put on markets one after another in 1991. Progress in humangenomic analysis has led to implementation of gene therapies and diagnoses using genes on gene diseases. Sweeteners used in a large quantity in the foodstuff field are fructoses made by isomerizing glucose produced by using enzymatic bioreactors. Needless to say about production of amino acid, organic acids, saccharides, antibiotics, steroids, and nucleic acid-based compounds by using enzymatic bioreactors, chemicals including acrylic amide from acrylonitrile, enzyme detergents, and bio-herbicides are available commercially. Progress in the technology is seen in all of the fields, including electronics industry and environmental preservation. 6 refs., 4 figs.

    Industrial polymeric foams were developed near the middle of the twentieth century. A chemical blowing agent or a physical blowing agent was used to liberate a gas for expanding polymers by foams. Before the 1980, CFC was used because of its high solubility, volatility and nontoxic nature. However, its stability and reactivity with ozone raised substantial concern about ozone depletion. Since the late 1980s, responding the Montreal Protocol, polymeric foam producers started researches and made big efforts to switch CFC to friendly alternative blowing agents. In mid 1980s, the microcellular foaming created by super critical CO{sub 2} was presented in the United State. The central idea of microcellular foams was to create a large number of bubbles, smaller than the pre-existing flaws in a polymer product. Since then, a large number of innovative applications have been imagined and taken people's attentions because of the unique properties of microcellular foams. This article addresses the sate of the art of the foaming and discusses what we could elucidate so far and what we should know in the future to assure more success in foaming technology in the 21 century.

    Carbyne has two isomers. One is {alpha}-carbyne (or polyene) wherein the primary bond and triplet bond are in cross-conjunction to each other, and the other one is {beta}-carbyne (or polycumulene) formed by double bonds only. They are slightly different in the bond distances and the crystallographic parameters. In this paper, after explaining the structure of carbyne, the synthesis method of carbyne is described. The methods for synthesizing carbyne are classified roughly into physical method using the high energy beam of arc discharge, laser or the like, and chemical methods. In the chemical method, the conjugate chain is constituted by the de-halogenated hydrogen from halogenated hydrogen carbine in chain-shape, but this method is unsuitable for synthesizing the pure carbyne since a part of halogens are remained therein. Therefore, the scheme of synthesizing the carbyne in annular shape and then isolating the same is proceeded with, and the succeeded examples are introduced. 7 refs., 1 fig., 1 tab.

    Relating to the paint industry, introduction was made of environmental problem, particularly trend of the hydrocarbonexhaust regulation, and problem against the global warming gas and acid rain. Environmental pollution matter produced by the paint industry and painting industry being mainly hybrocarbon (organic solvent), the worldwide quantity of hydrocabon exhausted in the atmosphere is estimated to be annually 20 million tons, of which 18%, i.e., an annual quantity of 3.5 million tons is exhausted from the field of paint industry. The role to be played by the paint industry is important for the lowering in pollution by the hydrocarbon. Useful paints for the environmental maintenance comprise high solid paint, aqueous paint, slurry paint, powder paint and UV-hardened paint. The automobile coating is being also changed from the metallic coating to the aqueous coating. Low temperature hardening paint is used for the countermeasures against the global warming gas. For those against the acid rain, urethane hardening, hardening by the acid-epoxy group reaction, hardening by the alkoxyl froup reaction and other hardenings are developed to replace the conventional hardening by the melamine resin for heightening in acidproofness of paint film. 5 ref., 1 fig., 3 tabs.

    This paper describes environmental hormones. Hormones are directly secreted from endocrine gland into blood flow, and play an important role of the differentiation of textures of organisms, reproductive function, metabolism, and adjustment of nervous/immunity system. There are some substances with hormone and anti-hormone reactions within the body of organisms, which are discharged as chemical substances in the natural environment by the artificial production activities. These are extrinsic endocrine disrupters, i.e., environmental hormones. There are 67 kinds of doubtful substances. When the environmental hormones work on the certain reaction stage of hormones, the normal action of hormones is disturbed. Various anomalies of wild animals have been reported in the world, which are suggested to be caused by the environmental hormones. Effects are known on the health of Homo sapiens, such as malignant tumor. In the current stage, test methods are under development, by which the presence of endocrine disruption can be screened. The effects depend on the growing stages of organisms, and it is necessary to consider the effects on various generations. 20 refs., 2 figs., 4 tabs.

    Studies are conducted to develop a new wet method for copper concentrates to replace the conventional dry smelting method for the settlement of problems involving the processing of impurities for environmental protection. A specimen of pyrites polycrystals is subjected to leaching at 80 {degree}C in a strongly acidic cupric solution. Findings are that the element sulfur generated in this process does not impede leaching and only approximately 4% of the sulfur is oxidized into sulfur ions; that the presence of more than 2g/liter of bromide ions produced during bromine-aid leaching of gold changes the structure of sulfur for the inhibition of leaching; that circulation of a bromine-containing leaching liquid is not desired since even a small amount of approximately 0.02mol/liter inhibits the leaching rate. Controlled potential electrolysis is performed for the anode in an acid solution containing CuCl, NaCl, and NaBr, for the observation of oxidation/reduction potentials predicted by Nernst`s equation. It is then disclosed that bromine is more effective than chlorine in gold leaching and that the solution potential during leaching agent regeneration enables the monitoring of solution constitution. 2 refs.

    The author, et al., have developed a formal evaluation theory for errors in numerical solutions and derived on the basis of this theory the conditions that a modified error minimizing operator should satisfy. A modified operator was derived for a calculus of finite difference in the time domain making use of this error evaluation theory. In this study, a modified operator was derived for O (2, 2) in the calculus of finite difference in time, and the operator was used in the calculation for the old and new methods about 1-dimension inhomogeneous media, and the two were quantitatively compared in CPU time and calculation accuracy. The calculation used 500 space grids and 5000 time grids. With the ratio of the time grid gap and space grid gap are kept constant, both CPU time and calculation accuracy were in proportion to the square of the number of grids. It was found in view of the result that the new method, as compared with the old method, needs only approximately 1/20 of CPU time in performing calculations of the same precision and that it maintains calculation accuracy that is approximately 20 times higher in the said CPU time. 4 refs., 2 figs., 1 tab.

    In the refining process for the production of copper from pyrites, heat treatment is carried out in a neutral atmosphere so that part of the sulphur will be collected in the form of simple sulfur and that pyrites naturally low in reactivity will be made active. A basic study is also conducted of a very high speed electrolytic method. The chemical aspects of pyrites which are various in composition (mainly CuFeS2) are clarified by X-ray diffraction, and then is subjected to heat-treatment in a 773K-1073K argon atmosphere. There is a decrease in the amount of sulfur at a temperatures not lower than 973K. The X-ray main diffraction line splits for the emergence of some lower angle diffraction lines. The specimen is then subjected to a leach test in a copper chloride base liquor, to disclose that leachability grows remarkably higher in the presence of a great change in the X-ray diffraction lattice constant. An experiment follows in which an electrolyte is allowed to flow at a high speed for accelerating the rate of electrolytic refining in an effort to prevent the passivation of anode and deposition of dendrite on the cathode that is apt to occur when the current density is high. Passivation is prevented when the flow rate is 10m/min or higher in the vicinity of the anode surface for the formation of a smooth electrodeposited surface. 2 refs., 2 figs., 2 tabs.

    The paper studies the measures for reduction of environmental load of CO2 from the standpoint of chemical technology. As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

    Among the research cooperation in the development of laser radar for environmental measurements with Indonesia between FY 1993 and FY 1996, results of the research and development of the environmental network are summarized. For the environmental information network, the Tokyo NOC is linked as an Internet connection point in Japan with the Jakarta NOC using an international dedicated line with a capacity of 64 Kbps. The Tokyo NOC is linked with domestic environmental information researchers using Internet. Thus, data stored in the data processing system of laser radar can be exchanged, information in both countries can be exchanged using E-mail, and data can be accumulated. For the research cooperation with Indonesia, research of path control and information relay server, research of effective transmission of data on the network, and research of multimedia communication have been conducted. The multimedia communication, distributed processing, and extension of dedicated line network using PPTP have been also conducted. 39 figs., 4 tabs.

    ISO14001 (Environmental management systems) came into effect internationally on September 1, 1997. The objective is continued improvement of environment to harmonize with continuous development of economy, expecting enterprises to tackle the system voluntarily. The point of ISO14001 and environmental impact assessment, which is the most difficult subject to understand, are described. ISO14001 becomes the subject of inspection and authentication, and sufficient study and preparation are required for the part of enterprises. Enterprises are required to clearly publicize the system as a top management system. `Environmental aspects` and `environmental impact` are analyzed and evaluated, and the process of connecting with the `environment objectives` and `environmental targets` is explained. To grasp environmental aspects, activities and processes by the operation of the enterprise itself must be extracted for the `input` and `output.` The process of `environmental impact assessment` is put in order and shown. 7 figs.

    For the purpose of contributing to the research cooperation project on the development of a laser radar for environmental measurement, the paper surveyed the present and future trend of the environment related information network in Indonesia. The survey was conducted in terms of a name of the network, the main administration body, the number of users, the utilization status, the use protocol, details of service, domestic mode installation sites and the main administration body, accounting system, types of the network used, reliability and stability of network, limitations on the use and details of the limitation, etc. The plan for expanding telecommunication equipment is being advanced in a very quick tempo. However, there are many problems in digitalization, and it is feared that the plan will be delayed. As to telecommunication quality and connection quality, the telecommunication completion rate, SCR, is very low, approximately 24% on average, which is equal to that around 1990 in Japan. The business service for users is all bureaucratic since they have a lot of applications for the installation piling up with no exception to the rule of developing countries. 23 figs., 10 tabs.

    The environmental endocrine disruptor, or the so-called environmental hormone, is outlined. Hormones are secreted from endocrine glands in trace amounts, transported by blood, and exert influence on the target organs and distal cells, this to sustain constancy in living organisms. There are two types: peptide hormones which are rows of amino acids and steroid hormones which are composed of cholesterol. Endocrine disruptors are chemical substances discharged into the environment which, once taken into human organisms, disrupt endocrine systems, some acting like female sex hormones and others resisting male sex hormones. Many a wild animal are found affected by them. They are accumulating in human organisms too. Synthesized chemical substances such as DDT, PCB, dioxins, and alkylphenols present in the water system affect a fish by disrupting its endocrine, immunity, nerve, growth, and regeneration. Embryos and larvae are quite susceptible, easy to turn abnormal. Voices are high across the world for the study of environmental endocrine disruptors. Introduced in this report are some animal experiments, typical cases of impact on the ecosystem, and systems for detecting environmental endocrine disruptors. 36 refs., 1 tab.

    This paper presents the activity of a consumers` organization in Hyogo-ken for diffusion of environment-friendly products. The product evaluation committee lists the concept of such products as follows: less consumption of resources and energy, possible cyclic reuses, reasonable and appropriate package, and less refuse and possible reuse as resource. This committee determines the products to be recommended, based on selection of products and producers, questionnaire answers, and survey results by consumer monitors and specialist group. The current number of recommended products is 24 in group or 312 in brand, and a half of such products are composed of recycled paper, aluminum and plastic products. The recommended products are renewed every two years. Although the recommended products have steadily increased during the activity for 5 years, the kinds of products are insufficient because of high price, less kinds of products, and insufficient PR. Education, wide information supply (symbol mark), and promotion activity for purchase (joint purchase, model shop) are important in the future. 1 fig., 1 tab.

    A compact and lightweight underwater RTV robot (RTV-SHIP) that enables the remote sensing in the double-shell structure of a tanker and the six-freedom motion control was developed based on the technology of the conventional portable underwater robot. The motion performance test in a water tank showed that the RTV-SHIP can freely access the manhole in the double-shell structure of a tanker and completely satisfies the thrust and swing force required for movement and measurement in a tank. The in-tank function confirmation test also shows that the main measurement items such as positioning in the tank, large deflection of panels, and plate thickness have a satisfactory measurement accuracy and that the RTV-SHIP has the same tone discrimination function as for a visual check. The method of inputting the tank shape during measurement and miniaturizing the recording unit should be improved until the RTV-SHIP is put to practical use. This system can be widely used by improving the above points according to the result of a future measurement test for the actual ships. 1 ref., 9 figs.

    This paper introduces conceptions on electrolytes, and describes new conceptions on electrolyte salts and their future prospects. What is evaluated in fundamental discussions on electrolytes is ion conductivity. LiPF6 has poor thermal stability, but provides high conductivity and is stable at high voltages, hence used as electrolyte for lithium ion batteries. The ion conductivity of an electrolyte is proportional to dissociated ion concentration and its mobility, and also to degree of dissociation of lithium salts. (CF3SO2)2NLi and (CF3CO)2NLi having two of the same electron attractive groups show two times greater ion conductivity than CF3SO2Li and CF3CO2Li. Electrolytes having oxidation resistance to be used in lithium ion batteries are LiPF6 and LiBF4. 3M Corporation has developed a method to stabilize imide salt electrolyte. Application of imide-based lithium salt as polymer is also studied. Development of new lithium salts, including synthesis of anionic species with weak orientation is under way. 22 refs., 5 figs., 5 tabs.

    A hybrid or mixed structure (composite structures) are a matter of increasing concern which takes in each advantage of steel and concrete. A field of bridges is no exception, with the plan and construction carried out for the new type of composite bridge, such as a composite cable-stayed bridge and a composite extra dose bridge as a long span bridge, and a composite truss bridge and a corrugated steel plate web bridge as a medium-span bridge, with technological development becoming active in this field. In such a technological trend, a hybrid two-girder structure was devised, a structure consisting of a concrete filled steel pipe for a girder and a precast (PC) floor plate for a floor board, as the girder structure of a long-span cable-stayed bridge in the subject research; also, applicability was examined using, as an example, the composite cable-stayed bridge with hybrid girders employed for the span. This paper reports the result of the analysis of the entire system, the analysis made for the purpose of examining the characteristic and the feasibility of this hybrid girder. The analysis revealed the structural feasibility of the long-span composite cable-stayed bridge using two hybrid girders of concrete-filled steel pipes thus devised. (NEDO)

    Methods were studied for determining the initial travel time and ray paths with stability when an non-linear travel time inversion is performed in an inhomogeneous structure. The travel time calculation was based on Faria and Stoffa`s method. First, the 2-dimension space was sectioned by grids, and `slowness` was assigned to all the lattice points. Starting from the vibration source, travel time at each lattice point is sequentially calculated. This method calculates travel time for any structure without breakup. In this study, an algorithm more sophisticated than the method of Faria, et al., was developed, and the improvement of travel time calculation accuracy led to the accurate determination of the direction of incidence into the lattice points during the initial motion. The calculation of ray paths was effected by tracing back from the receiving points the incidence into the lattice points or by following back the ray paths to the vibration source. This method performs stable calculation for a heavily inhomogeneous structure and, with the algorithm being simple, do the parallel programming as well. 1 ref., 6 figs., 1 tab.

    This paper reports a method to develop a new finite element by source (FES) for a two-dimensional plane problem and a three-dimensional solid problem as a method to analyze ship body structures. The paper describes development of a plate bending element by using a similar method, and the fundamental principle thereof. The present method can prepare a finite element of an arbitrary shape by simply providing a contact point only on a boundary. It can also derive good calculation accuracy with less number of contact points and elements. These facts are shown by examples of analyses on a square plate, a triangle plate and a semi-circular plate. Particularly, since a plate bending problem has a large order of differential calculus in a governing equation, this method being a semi-analytical method derives a result with very good accuracy even with less number of contact points. A hypothetical boundary method or a hypothetical electric charge method presents not a very high accuracy even if a large number of contact points are provided. This is because the method hypothesizes only a bending moment vertical to the boundary, but does not consider a source of the moment relative to the boundary. In contrast, the present method hypothesizes both of bending and twisting as the sources, hence its accuracy is better than with the above two methods. 5 refs., 11 figs., 7 tabs.

    The catalyst creating environmental conservation and comfortable environment is generally named an `environmental catalyst (EC).` EC is roughly classified into direct and indirect type ECs. Purification catalysts for automobile exhaust gas, and catalysts for chemical production process are under investigation as direct and indirect type ECs, respectively. The catalyst was found which can remove NOx under the coexistence of oxygen by using hydrocarbon as reductant. In addition, the practical exhaust gas purification catalyst was also developed for lean-burn engines by combining noble metal catalysts with NOx absorbing materials or zeolite superior in reductant adsorbing power. {epsilon}-caprolactam as raw material of nylon 6 is synthesized from cyclohexanoneoxime through Beckmann` rearrangement reaction. Zeolite system solid catalysts using no ammonia are under investigation. An environment-friendly synthesis method using not phosgene but catalyst was proposed for production of dimethyl carbonate. How to utilize catalysts for global material circulation remains unsolved for the future study. 5 refs.

    This paper outlines the synthesis and characteristics of substitutive materials of asbestos. Oxide system fibers are used as substitutes and classified into natural and synthetic fibers. As natural substitute, wollastonite fiber is used, while as synthetic substitute, silicate system, alumina system, zirconia system and potassium titanate system fibers are used. Wollastonite distributes in regional metamorphic rock and contact metamorphic zone between limestone and plutonic rock, and is used as heat insulator and adiabator. Silicate system fiber includes glass fiber, quartz fiber and silica fiber, while alumina system fiber includes alumina/silica fiber and alumina fiber. Glass fiber is composed of non-alkaline boro-silicate glass and classified into lint and staple. As fibers similar to glass staple, rock wool and slag wool are used. Only slag wool is produced in Japan because of its lower cost and higher qualitative stability than those of glass wool. Potassium titanate system fiber offers excellent heat resistance, thermal insulation and frictional resistance. 18 refs., 13 figs., 9 tabs.

    In order to develop an airborne asbestos monitoring system, the efficiency of FAM (fibrous aerosol monitor) was evaluated in which the scattered light due to vibration of fibrous particles is detected by applying He-Ne laser to the particles after vibration was induced in them by high voltage quadrupole electrodes. As compared with the data concurrently obtained by phase contrast microscope (PCM) and transmission electron microscope (TEM), no correlation of an asbestos concentration was observed between FAM and PCM in low concentration environment, however, FAM offered comparatively reliable results in high concentration environment. As an asbestos concentration was measured with time by FAM around a duct outlet during removal of sprayed-on asbestos, FAM responded instantaneously to emergent emission of a large amount of asbestos in the event of dust collector failure for example. FAM was thus useful for monitoring asbestos leakage. 8 refs., 6 figs., 3 tabs.

    This paper describes underground environmental issues to which geophysical exploration can be applied. Especially, ground pollution, waste treatment and unexploded ordnance (mine) detection are discussed by considering worldwide technology trends through examples in Japan and the USA. Since environmental surveys are generally conducted for regional and rather shallow ground, rapidity, economy and high resolution are required for geophysical exploration. In response to these demands, a mapping system using capacitor electrodes and a complex resistivity method for detecting organic compounds are promising for the electrical prospecting. A shallow electromagnetic method is being standardized for the electromagnetic prospecting. A cesium magnetic gradient meter is also being standardized for the magnetic prospecting. An underground radar, seismic prospecting, and gravitational prospecting are also applied to some grounds. Prospecting of pollution sources, high- and low-concentration ground pollution, monitoring of pollutant removal, soundness survey of water barrier in management-type waste treatment place, and detection of unexploded ordnance are illustrated for the examples. 15 refs., 10 figs., 4 tabs.

    This paper describes a problem on environmental hormone. Various chemicals discharged into environment act as hormone- like or anti-hormone-like substance. Since many such chemicals act as female hormone-like substance, those are called '(exogenous) endocrine disturbing chemicals' or 'environmental hormone'. Such chemicals include already regulated toxic PCB and dioxin, and a large amount of plastic raw materials, plasticizer and surfactant with no acute toxicity. The action mechanism of endocrine disturbing chemicals is as follows. Those bond with acceptors in place of hormone, and give incorrect directions to genes. Those may cause various disorders such as reproduction anomaly, development anomaly, immune toxicity and neuro-toxicity over several ages. For wild animals, some conceivable effects are being revealed. Since living organisms have various specificities and various experiments possible for animals are impossible for mankind, many obscure points remain unsolved. This paper presents various approaches in Japan. (NEDO)

    Various physiological reaction of plants would be obstructed and troubles of their growth would be met under environmental pollution. There are also cases that the polluted materials as nutritious components are absorbed by plants. Consequently, if plant's reaction on this environmental pollution would be used, indexes of environmental pollution and environment can be improved. For examples, Ipomoea Nil and Petunia having high reaction on photochemical oxidate are widely used as index plant of air pollution. Zelkova trees and poplars planted as street trees can also greatly absorbed the polluted gas and have a function to clear air. In this paper, a diagnosis method by visualizing plant's reaction on environmental pollution by using technique of image measurement was explained. As devices of usable image measurement, a thermal camera, a solid measuring cameras, an ultrasonic camera, a multi-spectral camera and an X-ray TV camera were given. 6 refs., 4 figs., 1 tab.

    In order to promote the interchange of environmental technologies mainly with developing countries (APEC countries), the concrete survey on construction of the information network for technology transfer was carried out. The useful information about environmental technologies for developing countries are not the latest Japanese information but actual field information in practical use which have been developed on the basis of constant improvements. Developing countries want clean technologies with less environmental burden, and difficult-to-obtain information for small and medium-sized businesses. Data were thus collected mainly in the Chubu district, and the information system was composed of an Internet server and in-house LAN. The system featured by easy retrieval and maintenance of the database was adopted. In addition, Internet connection environment and information needs in developing countries were surveyed. Expansion of the database and information supply, and constant addition of fresh information by continuous maintenance are essential in the future. 6 figs.

    This paper describes the recent trends in the environmental problems created from used plastic packaging materials. The 23 wards of the city of Tokyo produce refuses daily of 12,000 tons (1990), with plastics accounting for 15% by volume. Discussions to deal with plastic refuses that are bulky and standing out began as early as in 1971 when the disposal study meeting was inaugurated. As a result, wastes from polyvinyl chloride sheet for agricultural green houses had 40% recovered and recycled out of 100,000 tons generated annually, and styrofoam wastes at 10% of 150,000 tons. The wastes disposal law and the recycling law were established in 1991 aiming at reducing volume of wastes, promoting re-utilization, and assuring appropriate disposal methods and facilities. The Wastes Re-utilization Association was organized to handle styrofoam wastes that are attracting strong attention recently, the association having begun its activities with a good start. It is expected that styrofoam wastes will be molten thermally and regenerated into the same styrofoam products. Styrofoam could be more energy saving and resource saving material than paper cups. 6 refs., 10 figs., 5 tabs.

    Activities to build environments where familiar living creatures live have become active among citizen`s communities and local governments. This paper describes the ways to restore waterside ecological environment using dragonfly as a parameter, and examples of the restoration in urban areas, suburban areas and mountain valleys. The importance that comes first is to establish the future image, for which ecological design must be worked on based on surveys of diverse vegetation blocks. Vegetation transition rate is very high in Japan, where grasslands of low height change to high grasslands in two or three years causing change in living creatures that live therein. This condition requires such controls as mowing, felling, and mud dredging. Building an environment where dragonflies can live needs the water quality to have BOD at 10 mg per liter or lower. The egg-laying methods of dragonflies are divided into the water surface striking and egg-laying in plant tissues. It is necessary to prepare environments that suit species, such as stalks of Zizania protruding at watersides that facilitate dragonflies to emerge, grasslands where they find the places easy to live, and adequate degrees of sunlight irradiation. Very small modification of an environment often results in a great effect. 8 figs., 1 tab.

    In order to clarity the relationship potential of lacustrine source rock and depositional environment, cutting samples of the well drilled offshore Tenasserim, Myanmer were investigated for geochemical analysis. This basin is half-graven type basin formed in Tertiary and consist of terrestrial {approx} shallow marine sediments. According to palaenvironmental analysis, freshwater {approx} brackishwater lacustrine environment was spread during Miocene. Generally, source rock of this lacustrine sediments have high potential that TOC contents are 0.58 {approx} 3.61 % (Fair {approx} Very Good) and HI value area 136 {approx} 686 mg/g (Good {approx} Very Good). It are especially high that source rock potential of lacustrine sediments were influenced by brackishwater. As a results of maceral analysis, it indicated that source rock potential correlate closely with maceral compassion. High potential samples were characterized high amorphinite content. This result suggest that brackishwater influence develop anoxic environment and prevent organic matter from oxidizing. (author)

    Shiroi town, Chiba pref., acquired the certification of the international standard `ISO14001` for global environment preservation first in Japan on Jan 30, 1998. The basic approach is composed of planning of a practicable plan by staff himself (herself), and continuous improvement for fixing it through self-awareness. The degree of achievement of 4 numerical targets planned is as follows. Use of office paper was reduced by nearly 19% against a target of 10%, summing up to nearly 350,000 sheets or nearly 350,000 yen in reduction. Power consumption was reduced by nearly 2% against a target of 1%, nearly 370,000kWh or nearly 540,000 yen in reduction. Use of herbicide was reduced by nearly 98% against a target of 10%, 140,000m{sup 2} or nearly 2,260,000 yen in reduction. Eight low-pollution vehicles were purchased against a target of 7 vehicles. Carbon dioxide emission was reduced by nearly 7,000kg through reduction of power consumption, introduction of a garbage treatment machine, and severe use control of official vehicles. (NEDO)

    This paper describes the `Environmental management system` of ISO. This standard was made as a part of the contribution of industries to Rio Summit. It was initially an sustaining standard, and was unified by ISO. Some items to be adapted are required for certification-registration. However, the conditions are judged by the completion and adaptation of system and its effectiveness on the basis of three promises, i.e., continuous improvement, observance of laws, and prevention of pollution, in which the current level is not directly considered. It is significant for the system to define the responsibility, authority, and route of report. It is necessary to identify parameters for monitoring and measuring the operation and activity which provide remarkable environmental impact. Principle of the system introduction is top-down. The decision-making is a premise. The certification-registration recognizes that the environmental management system constructed by company or organization satisfies the required standard, but it does not guarantee the environmental performance. It depends on how to achieve the plan and purpose by using the system. 3 figs., 2 tabs.

    Discussion is made on the recycling of resources which is one the very important problems for the global environment and human activity. In consideration of the limited natural resources and utilization by the human race of the resources for long, recycling of resources'' for saving resources is extremely important. The scale of the waste treatment industry in Japan is estimated to be between 4 to 5 trillion yen which exceeds 1% of the GNP with the trend of increase year by year, and the industrial waste treatment industry is taking root in Japan. Recycling'' can be grouped in three methods, i.e. recovery of materials, conversion of materials, and conversion of energy. The primary object of recycling is to spare resources and save energy. Recycling is of deep significance from the viewpoint of energy saving. There is a big merit in the conservation of dumping sites. Making best use of the useful secondary resources in the wastes is directly connected with the solution to the problems of prolongation of resources'' and conservation of global environment'' with which the human race is now confronted. 7 refs., 7 figs., 2 tabs.

    New city concept is studied from the viewpoints of city economy, environmental symbiosis, energy and resources, transportation, urban disaster prevention, information dissemination, etc. As the result, twelve cluster cities equipped with capabilities of state capital function and administrative business, commerce, interchange of people and goods, and recreational activities are dispersed and distributed to form a double ring, populated by 0.6 million and occupying 7000ha. In a simulation of the heat island phenomenon, the temperature is lowered by 0.2-0.3degC by the dispersion of city functions, and by 0.1-0.15degC by environmental symbiosis-related measures. Primary energy consumption is reduced by 17% by reduced demand for power and heat and energy saving of 15% is attained by recyclable energy utilization and enhanced-efficiency energy supply, all thanks to passive solar systems and higher-efficiency electric machines, photovoltaic power generation, heat pump-aided utilization of waste heat and environmental heat, electrothermal energy supply from the MCFC (molten carbonate fuel cell), etc. 64 refs., 56 figs., 25 tabs.

    Behavior of gas/liquid two-phase flow in tubes and behavior of air bubbles in liquid were investigated under the microgravity environment without convection by using the drop test facilities of the Japan Microgravity Center. To remove bubbles in the liquid under gravity, the strength of surface tension acting on the gas/liquid interface was made inhomogeneous. In this case, the moving velocity of bubbles on the gas/liquid interface was able to be raised up to the maximum of 2.4 mm/s. For the movement of bubbles in the horizontal direction under the condition of low relative velocity independent of the size of air bubbles in the duct, bubbles moving in the horizontal direction under 1g flowed almost linearly accompanying with the liquid flow. For the air bubble distribution in the bubble flow, where small bubbles flow in the vertical tubes, the fluid pattern of air bubble flow under 1g and {mu}g depended greatly on the initial condition of mixed bubbles. Fundamental data were obtained, as for the transportation and control of multicomponent bubbles, bubbles in the sound field, and bubbles in the liquid phase by magnetic force, and the fluid phenomena of bubbles in the subcool boiling region, a single bubble in the gradient electrical field, and bubbles in the tubes with small diameter. 47 refs., 97 figs., 8 tabs.

    In Candidate C area for the geothermal development survey, the natural environment was surveyed and `the secondary landscape assessment` was summed up in which places proposed for drilling of large-size wells and for construction of power generation facilities are extracted and a simulation of the landscape is conducted. The area for survey is the Shiramizu-gawa region in the south of Lake Akan, Akan-cho, Akan-gun, Hokkaido. The field survey was carried out about three items of landscape, plants and animals during the June-November period, 1995. As to the flora, diverse florae including vegetation unique to alpine areas, wetlands, and fumarole surrounding areas were found in the region, which is covered with summer-green broad-leaved forests or mixed forests of coniferous and broad-leaved trees. As to the fauna, faunae inhabitant of the highly natural forests were found including black woodpeckers and mountain hawk eagles. As a result of studying the places proposed for geothermal development from the above-mentioned survey, two places were picked up in the west of the survey area, where geothermal development is comparatively less influential in the natural environment and landscape and there is a high locational adaptability. 19 refs., 56 figs., 49 tabs.

    The relationship between environmental control and biotechnology is discussed, and purification of moats and lakes is taken up as a concrete example of introducing biological waste water treatment technology to ecotechnology. In addition, an overall waste disposal system connecting cities and agricultural districts is investigated. After the purification of water and waste problem solution, etc. are discussed, the importance of creating ecopolis and ecotown is described. The 3 concepts of microbial ecotechnology (high densification of organism, field control, interaction between organisms) are used to explain biological treatment technology. Attempts for direct purification and ecotechnology are described quoting a few examples. If waste produced in cities and ligneous materials or charcoal obtained from forests are mixed for treatment, effective waste treatment or new resources production may be possible. It seems to be possible to create ideal ecopolis and ecotown by applying the doctrine of irrigation, drainage and reclamation engineering and the technology established by now. 35 refs., 1 fig., 2 tabs.

    Tasks to be fulfilled in relation to the plumbing system for reduction in environmental loads are discussed. They are the effective use of water (saving), extension of equipment life, and the adoption of materials imposing less load on the environment (ecomaterial). In the case of a hot-spring hotel M of Tottori Prefecture, water saving efforts are exerted by guiding the hot-spring water through a radiation coil placed in a fall-provided pond for temperature reduction. In the case of a hot-spring hotel S of Iwate Prefecture, for the effective utilization of hot-spring water gushing out in abundance, a heat exchanger is installed for exchanging heat between the hot spring water and city water. The thus-warmed city water is fed to room baths and to taps in the public bath, and the hot water overflowing the public bath is utilized as the heat source for a wastewater heat recovery heat pump before being discharged into the river. As for equipment life extension, there is for instance the case of vinyl chloride pipe which has been in use for the purpose of cost reduction. Since it is expected that the life of plastic pipes will be more than 10-20 years longer than that of metal pipes, it has become necessary to consider the issue of ecomaterials. 5 refs., 4 figs., 5 tabs.

    Learning from a history of the earth of ancient times, the paper studies effects of refreshing environment and soil or making them natural and harmless mostly using primitive bacteria, and develops element technology which is industrially accelerating. The spread type accelerator working only by solar energy was installed and operated for experiment. As indices of refreshment effects, a study was comparatively made between a sugar degree of sweet potato and a yield shown in the number of potatotimesunit weight. An EM propagation garbage layer is formed, and the two sections were installed of a site of the actual installation of the spread type accelerator and a site naturally left alone. Other effects of weather, temperature and humidity which are external factors and general fertilization are offset as common modes, and a consideration was so made that only refreshment effects of primitive bacteria can be relatively compared. Acceleration effects in using accelerator for growing sweet potato could be quantitatively confirmed. As to sugar degree, because the last study was made in the beginning of summer, the underground temperature was high enough. Even only EM effects were fully effective. This time, the weather was much colder, and it was found to be a must to use accelerator. 2 figs.

    The paper studies the measures for reduction of environmental load of CO2 from the standpoint of chemical technology. As for methanol synthesis from CO2, accelerating of the reaction using Cu base compound catalyst is reported. Also, CO2 is methanated at high speed by low temperature waste heat using Ni-La2O3-Ru catalyst. Discussions are given on the subject for development of catalyst reaction relating to hydrogen production technology by methane reforming reaction using steam or CO2. Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced. Described are production of polyhydroxy butyric acid and biodegradable polymer from CO2 and hydrogen by bacteria, and CO2 fixation imitating the enzyme reaction. 267 refs., 79 figs., 32 tabs.

    The trend of technology is surveyed from a standpoint that, in the process of CO2 fixation using microbes for the production of useful substances, it is essential, in view of income/outgo balance and economy, to utilize their catalytic function. The survey centers about the feasibility of the utilization of organic wastes, cellulose wastes in particular, as an energy source. Special attention is paid to the energy of artificial light and laser beams. From a point of view that it is important to suppress cell multiplication and to effectively utilize only catalytic activity for the production of useful substances, the cell division mechanism of the Corynebacterium is analyzed, and the findings are compiled to facilitate the study as to whether the division may be controlled. A report is also prepared on the metabolic mechanism of a photosynthesizing bacterium that is judged to be the most promising species. Reference is made to aerobic and anaerobic bacteria. Shown are the organic compounds that are formed by CO2 gas fixation thanks to microbial or enzymatic reactions. To emphasize their importance as an energy source and to explain the conversion of biomass into useful substances, the technology and economy of conversion into fuel compounds are surveyed. The production of ethanol out of organic wastes is evaluated in the way of LCA (life cycle assessment). (NEDO)

    For many refractory materials, vapor pressures rise due to fluoridation. For example, a vapor pressure of B is almost zero at room temperature, whereas a vapor pressure of BF{sub 3} is 10{sup 5}Pa or greater. A SF{sub 6} plasma method is capable of directly generating a solid fluoride in an ion source and obtaining its plasma. In order to ionize refractory materials such as niobium, boron, silicon and the like, the present authors have developed a new ion generation method using a stable solid sample and SF{sub 6} gas. Further, the present method was employed to successfully and greatly extending the filament life of the ion source. The plasma method can be used widely not only for a Freeman ion source but also for an ion source using plasma such as electron cyclotron resonance (ECR) ion source. Since the refractory material ions can be stably supplied at a great intensity for a long time, they are expected to be used in corrosion-resistant materials or materials having new functions such as optical switching materials.

    Contributing shares of increase of CO {sub 2}, CH {sub 4}, and N {sub 2} O, to that of greenhouse effect is estimated, by referring to recent scientific knowledge, as 57% by combustion of fossil fuel, 20% by destruction of forest, 9% by agriculture and stock-breeding, and 14% by natural causes. During the past 100 years until 1980, 66% was attributed to CO {sub 2} for increase of green- house effect, contrary to 49% during the decade of 1980s. The most reason why the effect of CO {sub 2} was diminished in that decade was for the reason of increased effect of freon gas, but in future when the abolition of freon is realized, the share of the effect by CO {sub 2} is expected to come back again. Global warming is to be considered for the range of 50-100 years, accordingly, accurate prediction is impossible because assumption for the counteractions affects on the result and unexpectable effects such as war and oil crisis can not be taken into account. In this report, analysis of past senario and that of EPA are conducted to obtain counter-measures to global warming. 16 figs., 10 tabs.

    Energy consumption of Japan increased proportionally to its growth of economy, then after, decreased its growth rate more than that of economy. Such fact commonly occurred, more or less, in the developed countries. Because of the fact, economy of Japan could grow steadily, in spite of economical turblence brought by the first and the second oil crisis, by avoiding shortage of energy. And, green house effect as the recent topic is suppressed after oil crisis by decreased rate of carbon dioxide generation. Such are brought by reduced rate of economical growth and of energy consumption per GNP, the latter can be said as energy saving in its broad meaning. In this report, progress of energy saving in its broad meaning was explained and clues for finding future possibility were studied. 7 figs.

    Shape variable laser beam shaping optics for which linear polarized beam is utilized is applied to the hardening of carbon steel by CO2 laser beam to analyze the absorptivity. In addition, linear polarized beam is irradiated to inclined materials for laser hardening to analyze the depth of hardening and the distribution of temperature. The absorptivity of random polarized beam by the bare specimens is as low as 20%. It is as high as above 40% with the graphite coated specimen, but is nearly constant with no dependence on the angle of incidence. The absorptivity in p-polarization increases with the increase in the angle of incidence. When linear polarized beam is used, the total efficiency of the bare specimen becomes high by about 1.5 times that of the graphite coated specimen subjected to random polarized beam. Hardening of bear material by laser beam is quite possible when p-polarization is employed. An approximation equation is derived with which the temperature distribution and hardened depth can be obtained easily if beam distribution and absorptivity are given, and it is applied to the evaluation of laser hardening of inclined specimens using linear polarized beam. 22 refs., 11 figs., 1 tab.

    This paper presents the analytical example of the ordering process of order-disorder transformation in Ni-Mo alloy using recent experimental techniques. Monte Carlo simulation clarified the fact that the ordering process in Ni4-Mo alloy is largely affected by short range interaction in the early stage of ordering, and forms D1a, D022 and Pt2Mo structure units with a similar atomic pair correlation. The ordering process is largely affected by long range interaction with an advance of ordering, and develops only D1a structure most stable in energy. In order to check the existence of SRO (short range order) structure obtained by Monte Carlo simulation, the analysis of high-resolution TEM images under SRO condition was carried out using the imaging plate recently developed for TEM. The analytical result showed that the observed N2M3 pattern is derived from not always the existence of N2M3 structure but superimposition of D1a, D022 and Pt2Mo structure units. 19 refs., 4 figs.

    These recent years, big cities like capital city as compared to suburbs are facing city heat island problem causing severe temperature increase. For example, there are measured results that the temperature around Nihonbashi, Tokyo, which has the highest density of energy consumption, was 4degC higher than that of coastal area having lower energy consumption density. The speedy increase of power consumption in summer due to massive cooling load is one of the main problem of heat island. The worse cycle of temperature increase is caused by the increase of heat liberated from cooler together with the addition of heat liberated from vehicles and so forth. Main measures for heat island carried out so far has been studied from the point of view of save energy technology for each such as efficiency improvement of heat pump cooling machine and combustion improvement of vehicles. In future, necessity of save energy measures from macro point of view that reduces the heat liberated in the whole city is cited. 24 refs., 7 figs., 3 tabs.

    For this survey, the latest technology trends relating to microbial functions are summarized to recover and effectively utilize CO2, typical greenhouse effect gas, using microbial functions. Systematic survey and analysis are conducted concerning the microorganisms useful for fixing CO2, CO2 uptake mechanism during the microbial reactions, utilization methods of solar light and useful energy sources except solar light, highly efficient production of useful materials, and usage of produced useful materials. Research has concentrated on use of biological activities for this purpose through design of bioreactors using microorganisms (bacteria and microalgae) for efficient CO2 fixation. For the process to have net CO2 fixation as assessed by its life cycle and to make the process economically feasible, it is essential not only to fix CO2 merely in the form of biomass but in addition to convert it to useful materials by the catalytic activities of the organisms. Three categories were set for the survey, i.e., microorganisms with CO2 fixation ability, available energy for CO2 fixation, and target CO2 fixation products. 169 refs., 49 figs., 14 tabs.

    A rough design was performed on a floating airport. On this floating structure, environmental external force was estimated, mooring design was carried out, and discussions was given on the position retaining performance important for airport functions and behavior of the floating structure. The discussion was given on cases that the airport is surrounded and not surrounded by floating breakwaters. A floating structure which becomes super-large in size requires considerations on force due to sea level gradient as a result of a tide. Deriving flow condition changes and force acting on the floating structure simultaneously by using numerical calculations makes it possible to estimate current force given with considerations on influence of the flow conditions created by installing the floating airport. Estimation was carried out by using a zone dividing method on wave drifting force acting upon the floating airport. As a result, it was found that installing floating and permeating type breakwaters can reduce the wave drifting force acting on the floating airport. The wave drifting force working on the floating airport can be reduced by installing the floating and permeating type breakwaters to lower levels than when no such breakwaters are installed. The airport may be moored with less number of fenders when the fenders of the same type are used. 18 refs., 10 figs., 5 tabs.

    With an objective for spatial continuous measurement of physical, chemical and biological amounts in ocean, development has been made on a wing controlled towed vehicle, `Flying Fish` which is capable of controlling depth, pitch and roll. Numerical simulations and two-year sea experiments have been carried out for the development. Flying Fish consists of a sub-system comprising a towing vehicle, towing cables, and on-board controllers. In a steady state, Flying Fish can be controlled at accuracy for depth of {plus_minus} 0.05m, pitch of {plus_minus} one degree, and roll of {plus_minus} 0.5 degree. This accuracy is sufficient for operating a chemical analyzer, the dissolved carbonic acid analyzer. Even in a non-steady state such as in changing the depth, the pitch can be controlled at {plus_minus} 3 degrees and the roll at {plus_minus} 0.5 degree. This extent of attitude change is within a range rendering no problems in maintaining accuracy of the measurement devices. The result of sea experiments for movements of Flying Fish agreed with that of the numerical simulation at practically usable accuracy. Flying Fish is verified as an effective system in investigating spatial variations in ocean data. 10 refs., 15 figs., 1 tab.

    This paper reports a summary of the large enviromntal application facility to perform strength tests on composite materials under varying temperature environments. The facility features the capability of providing uniform temperature and humidity distributions in an environmental space of 9[times] 5[times]3 m, and covering a wide temperature range from[minus]70[degree]C to 200[degree]C. Since the environmental room temperature of 200[degree] C is not sufficiently high to meet high-temperature structural testing requirement for HOPE, an auxiliary ceramic heater was brought into the environmental room to heat only the required area up to 350[degree] C. A hydraulic actuator including the already introduced high-load loading equipment was installed in a space under the environmental room rack, and loads are induced to an extension rod attached to the load terminal in the actuator. Tests scheduled include a fatigue test on CF/thermoplastic composite filament winding beams for high-altitude unmanned spacecraft under a use temperature of [minus]60[degree]C, which is under preparation at normal temperatures, and a high-temperature strength test on polyimide CFPP structure for HOPE to follow the former test. 5 figs., 1 tab.

    The paper outlined activities in fiscal 1994 in the R and D cooperation project on a laser radar for environmental measurement. In the activities in fiscal 1994 of `the ODA laser radar development committee,` the committee held four meetings, two field surveys were carried out, and two researchers were invited from Indonesia. In the field survey, the environment in Jakarta city was investigated in terms of changes in population and number of the cars registered. Further, from data collected during 1994-1998 in the central Jakarta city, the following were made clear: the trend of a decrease in SO2, the trend of a rapid increase and an excess of NO2 content over the environmental standard, the status of pollution of which the level is close to the upper limit of the environmental standard of dust, etc. In the meeting of the policy study for the field survey at LIPI headquarters, Japan proposed a system which is constituted of a difference absorption laser radar, two Mie scattering laser radars, and a central processing unit. The sites proposed were studied in cooperation with Indonesia. 40 refs., 65 figs., 9 tabs.

    Effectiveness of the spectral method was confirmed for system interconnection type photovoltaic (PV) power generation systems, and PV array capacity determined in harmony with the power load was investigated. In this study, system interconnection type PV power generation systems with polycrystalline Si and amorphous Si PV cell modules were discussed. The output electric energy evaluated by the spectral method was compared with that evaluated by the conventional method only considering the cell temperature. Obtained results are as follows. For the polycrystalline Si, the differences between solar supply rates in summer evaluated by the both methods and measured value were less than 2%, which resulted in the accurate determination. For the amorphous Si, however, the difference less than 3% was obtained by the spectral method and that less than 11% was obtained by the conventional method. The spectral method provided higher accuracy. When constructing a system with large array capacity, it was found that the optimum design of PV power generation system can be performed using the spectral method with less array capacity than using the conventional method. 4 refs., 9 figs., 4 tabs.

    Proposals have been made for the establishment of a network (ETERNET-APR) linking those involved in the research and development of environmental technology in the Asia-Pacific region in order to limit the environmental impact of industrial activity. By pursuing active exchanges of information and personnel, researchers in environmental technology in the Asia-Pacific region have been making serious efforts to establish such a network. This fiscal year, the Internet Web site of the ETERNET-APR has been created using the data collected to date. This database includes information on some 350 researchers and 200 research projects from seven countries. The first international symposium was successfully held at Environmental Research Institute of Chulalongkorn University in Thailand (ERIC), hosting 200 environmental researchers from 10 countries in the Asia-Pacific region. Tripartite sister laboratories ties among the National Institute for Resources and Environment (NIRE) and three Korean laboratories were forged. The sister laboratory project between ICETT and ERIC is also proving effective. These successes prove that intraregional joint research, the objective of ETERNET-APR, has begun to take shape in this year

    For active environment technology export to OECD countries, needs for environmental measures in developing countries were surveyed. Both collection of environment technology needs in developing countries and preparation of technology seeds information of Japanese enterprises, and promotion of environmental projects by adding an information dispatch function are important. Active preparation and exchange of experiences and know-how of concerned enterprises, local governments and national organizations are also necessary. For development and possible export of small- and medium-sized ventures with excellent technologies and know-how, a suitable consulting system is essential for risks. For smooth promotion of warming prevention by international cooperation, active development of monitoring technology is also important. To support developing countries, OJT of persons in charge in technology transfer sites, and preparation of information infrastructure are necessary. Japan with much know-how on environmental preservation should positively participate in international standardization activities such as ISO. 10 refs., 14 figs., 56 tabs.

    The ability that architectural space improves the thermal environment in comparison with outdoor environment is called the `capability of controlling thermal environment.` As the value becomes higher, the indoor thermal environment is more improved. In this paper, the controlling capability of six building envelopes with different window systems was compared. The heat transfer in the wall and window system is approximated using a lumped mass model of heat capacity to obtain a heat balance equation and combined with the heat balance equation in indoor air for backward difference. The wall surface temperature and indoor air temperature in a calculation model are then calculated. A radiation absorption coefficient is used for mutual radiation on each wall. In the model, the adjoining room or first- and second-floor rooms were made the same in conditions as the model on the assumption that the one-side lighted office in an RC reference floor is in the non-illumination and non-airconditioning state. In summer, the controlling capability remarkably varies depending on the window system. For the window facing the south, the annual capability is more advanced than in other directions and the indoor thermal environment is improved on the average. 7 refs., 12 figs., 1 tab.

Based on the achievements obtained by the surveys in fiscal 1995 and 1996, the ICETT has participated as one organization constituting the APEC environment technology exchange virtual center, and begun providing information since April 1997. As the environment technology information, those items actually employed by factories and operation sites in Japan are put into a data base, and into a home page including training information centering around those contained in the data base, and examples of works done by local governments for prevention of pollution. Furthermore in fiscal 1997, a simulation software for a model process has been developed. Fiscal 1998 strengthened the data base for environment preservation technology information, investigated environment preserving model companies and summarized them including even their management aspect. Investigations were carried out in developing countries on application of cleaner technologies. Gaps far exceeding anticipation exist in every field between these developing countries and Japan. Environment protection measures applied and succeeded in the developing countries as the means to narrow the gaps were collected, and compiled as the specific examples. (NEDO)

    The Chiba plant of Sapporo Breweries Ltd. has introduced a biogas-using fuel cell system as one of its efforts for environmental protection, and the system generated power in June, 1998, for the first time in the world. This paper discusses the efforts for environmental protection, power generating system, and future tasks. The biogas-using fuel cell system makes use of fermentation gas (biogas), produced when wastewater from the plant is subjected to anaerobic treatment, as fuel for the generation of electricity (200kW), steam (160 degrees C, 5.3kg/cm{sup 2}), and higher-temperature water (80-120 degrees C). The biogas is a low-calorie gas consisting of approximately 70% methane gas and approximately 30% CO2 gas. Since the gas contains trace quantities of approximately 1,000-1,500ppm sulfur compounds, and salts and ammonia not higher than several dozens in ppm, a pre-treatment device is installed upstream the fuel cell power generation unit for their removal. The merits brought about by the adoption of the system include the lowered electricity rate, reduced CO2 emission, damped noise, and enhanced maintainability. It is believed that the system introduced here will work advantageously in satisfying the ISO14001 requirements. (NEDO)

    This article describes the trends of negotiation for the United Nations Framework Convention on Climate Change, trends surrounding carbon tax or environment tax, and trends of global environmental problems in Japan. Tenth Intergovernmental Negotiating Committee for the United Nations Framework Convention on Climate Change was held in August, 1994. In EU, an action for introducing the carbon/energy tax has been activated for the First Session of the Conference of the Parties. Cooperation of the USA and Russia on the environmental problems has been also activated. Japan has communicated the action plan of individual countries to UN, which is based on the long-term prediction of energy demand and supply. In the Tenth Intergovernmental Negotiating Committee, the enhancement of CO2 emission control and the standard of joint implementation were mainly discussed. The total CO2 emission of Japan in 2000 is estimated to be 330 million ton, which is larger than the result in 1990 by 10 million ton. However, the amount of emission per person is estimated to about 2.6 ton, which is almost same as in 1990. In Japan, the environment tax has not been discussed, yet. 1 fig., 1 tab.

    This paper introduces an energy security model intended to achieve consistency in demand and supply of energies in Japan and assure stability as a system. The model divides an energy system into segments from supply to consumption and expresses each segment in demand functions. A cross impact method is used to analyze the function. The considered structural equations involve final energy demand functions, logit share function models for fuel substitution, electric power supply blocks, interrelations among prices for fossil fuels, economic activity blocks, and cogeneration systems. Examples of evaluating the future uncertainties include interruption of oil supply, implementation of a fossil fuel consumption tax system, strengthening of regulations on nuclear power generation, and introduction of cogeneration systems. These cases were applied to the above structural equations to perform a simulation. Suggestions were given on contribution of oil substituting energies to the security, and large effect of CO2 emission tax. 18 refs., 9 figs., 7 tabs.

    For the purpose of studying how the energy supply/demand structure in Japan should be, a report on the secondary IPCC (Intergovernmental Panel on Climate Change) evaluation was analyzed. Possibilities of reducing the world CO2 emissions in association with the energy consumption were studied in the five assumed cases. Every case says that CO2 can be reduced to 1/3 of the 1990 level by 2100. In a case of the use of biomass as main fuel (1), the use of primary energy is suppressed to two times the 1990 level, and photovoltaic/wind/biomass power generation is introduced in a large quantity. Synthetic methanol and hydrogen are used for transportation and commercial/residential use fuels. There are four more assumed cases: the use of nuclear power as a substitute for renewable energy in the power generation in (1), the use of natural gas of 1.5 times that used in (1), the substitution of coal for biomass used in (1), and the assumption that the demand for primary energy in 2100 will be twice that used in (1). In Japan it is assumed that basically the nuclear power generation will be expanded, that the photovoltaic and waste power generation will be introduced in a large quantity, and that synthetic methanol and hydrogen are mainly used as transportation and commercial/residential use fuels. It is necessary, therefore, to analyze conditions under which the quantity introduction of such non-fossil energy is made possible. 11 figs., 31 tabs.

    In this study, the actual condition of the energy consumption has been surveyed to compare the environmental loads in underground shopping centers with those in buildings on the ground, aiming at clarifying the actual thermal environment in underground shopping centers located in the Kanto area and the features of the thermal environment therein. The energy consumption was calculated by primary energy conversion on the basis of the average data obtained for the past three years. The survey of energy consumption in 32 underground shopping centers in Japan shows that all such places, commonly from Hokkaido to Kyushu, were the spaces consuming a large amount of energy. In the underground shopping centers, total energy was consumed four times as large as that in ordinary offices, energy for cooling energy consumption larger by 4 times, by 6 times for air cooling and six times, and energy for heating more than four times. They required energy twice to three times as large as that in department stores. The reason for it is considered that in underground, not only the 24-hour ventilation and air condition are required because of the public environment but external and internal heat loads are dealt with. 4 refs., 16 figs., 9 tabs.

    Offensive odor substances belongs to a quite different field from the perfume inspire of the same sense of smell, and is a substance forming a lot of troubles which is formed in intimate resident environments such as manufacturing factories of the chemicals, incineration and decomposition treatment process of living body relating substances, stock raising facilities, restaurants and others. A material called the offensive odor substance is generally in very low concentration in the atmosphere, most of which is ppm order in its detection limit. And, the offensive odor intensity is proportional to logarithm of its concentration. For example, even removing 99.9% of the offensive odor substance from its forming source, there is remained its difficult countermeasuring problem of no removing as its offensive odor. At present, the offensive odor is severely regulated by means of laws and acts, research on its relating field is active, and its relating publications have become plenty. In this paper, outline on recent state of the offensive odor and its measuring technique was summarized. 14 refs., 6 figs., 8 tabs.

    Information systems, mainly aided by computers, are becoming increasingly important, contributing to development of wide areas of societies and economics, to begin with. However, few developing countries have established sufficient information systems, in spite of their strong desires to do so, which will further widen the gap between them and advanced countries, where these systems are acceleratedly advancing. Given these situations, Center of International Cooperation for Computerization (CICC) has been implementing various projects for providing assistance to and cooperation with oversea countries which are trying to develop information systems. This report summarizes the project, which CICC has been commissioned by Optoelectronic Industry and Technology Development Association as part of the cooperation programs, for establishing the Asian environmental information networks.

    As one of the international research cooperation projects, the research cooperation in developing laser radar for environment measurement started between Japan and Indonesia. The project is scheduled to be carried out in a 4-year plan starting fiscal 1993. In fiscal 1993, conducted were negotiations with Indonesia on its implementation and a field survey. Between January 6 and 15, 1994, the first field survey was made in terms of topography, climate, road network and traffic situation of Jakarta city, and the proposed sites for installation were reported. The paper also introduced the reception system on the Indonesian side and a request for technical learning through stay in Japan. The second field survey was conducted between February 27 and March 6, 1994.

    In order to structure a chemical reaction process that does not discharge a large amount of waste by-products or harmful chemical substances, or so-called environment friendly process, investigations and discussions were given based on the results derived in the previous fiscal year. A proposal was made to reduce environmental load on development of oxidized and dehydrogenated catalysts that can produce selectively ethylene, propylene and isobutylene in an oxidation process. In liquid phase oxidation, redox-based oxidation and solid catalyzation of automatic oxidation reaction were enumerated. In acid base catalyst reaction, development of ultra strong solid acid was described to structure no pollution discharging process. In the fine chemical and pharmaceutical fields, the optical active substance method and the position-selective aromatics displacement reaction were evaluated to reduce environmental load. A questionnaire survey performed on major chemical corporations inside and outside the country revealed the following processes as the ones that can cause hidden environmental problems: processes discharging large amount of wastes, processes treating dangerous materials, and processes consuming large amount of energy. Development of catalysts is important that can realize high yield, high selectivity and reactions under mild conditions as a future environment harmonizing chemical process. 117 refs., 23 figs., 22 tabs.

    The analysis of the organic pollutant in the environment is carried out as the following procedure; the organic substance is extracted by using the organic solvent from a collected sample, an instrument analysis such as gas chromatography (GC) or high performance liquid chromatography (HPLC) are done after the clean up the sample by column chromatography. The analysis using supercritical fluid instead of the organic solvent in each stage is supercritical fluid extraction (SFE) or supercritical fluid chromatography (SFC). The supercritical fluid has a density and viscosity coefficient between gas and liquid, and the control of the dissolving power is possible by the change of temperature and pressure. Therefore, it has the advantage as follows: The material mobile speed is high and separation and extraction are rapid; It is easy to adjust the dissolving power and possible to carry out selective separation and extraction; The removal of solvent can be easily carried out since supercritical CO{sub 2} used is a gas in the normal pressure. In this paper, the analytical instrument in which the extraction is carried out in organic solvent and clean up was done in SFC was introduced. (NEDO)

    To investigate the energy demand and supply structure in Japan, the international trend of approaches to global warming problems and the mitigation options to global warming in the energy related sectors have been surveyed. For the United Nations Framework Convention on Climate Change, an Ad-hoc Group has discussed relevant topics after the 1st conference of the Parties. Meetings of the Group primarily focused on what objectives to set for the reduction of greenhouse gas (GHG) emissions in and in and after 2000. IPCC completed their Technical Paper in November 1996 in which technologies and measures to reduce GHG emissions and to enhance GHG sinks were analyzed and evaluated in various aspects. This Paper discusses about each sector of institutional buildings sector, transport sector, industrial sector, and energy supply sector. Especially, in the energy supply sector, promising approaches to reduce future emission include more efficient conversion of fossil fuels, switching to low-carbon fossil fuels, decarbonization of flue gas and fuels, CO2 storage, switching to nuclear energy, and switching to renewable sources of energy. 5 refs., 2 figs., 14 tabs.

    This report describes the impact assessment which is an important step for LCA. For classification of the impact assessment, the existing literature was reviewed and a skeleton for the classification was proposed. The weighting factors for nine selected impact categories, which were used to calculate environmental load point (ELP) for the valuation, were obtained for two overseas groups, i.e., students of Amsterdam University and SETAC Europe members. It was found that the former provided the similar trends to general Japanese, however that the latter gave high weighting in the global warming and depletion of ozone layer. The ELP was proposed and applied to automatic washing machine, coffee maker, waste incineration power generation system, and co-generation system. As a result, its effectiveness was demonstrated. This report also describes problems for the LCA of thermal and material recycling of PS trays. 99 refs., 96 figs., 73 tabs.

    This paper makes analyses of what policy and technological option each advanced industrial country thinks to take as measures for the global warming problem, at the same time clarifying the trends in international meetings. Analyses are also made of attitudes of developing countries and the international cooperation problem. Among the problems on global warming, an emphasis is placed on introduction of energy saving and what role the development of new energy plays. A positive group consisting mostly of West European countries is advocating a `Go Quickly` approach, while the US representing a prudent group is developing a `Go Slowly` approach. The US is considering afforestation which is useful to absorb CO{sub 2} and methane recovery as technological options. West European countries regard CO{sub 2} fixation as an important option. USSR, East European and developing countries consider that the most feasible and successful CO{sub 2} measures are energy saving/improvement of energy efficiency and forest administration/afforestation. 43 figs., 78 tabs.

    An analysis on the factors related to carbon dioxide (CO {sub 2} ) emissions in the past, was conducted. Then, an option menu of measures to prevent global warming including alternative energy-related ones, was discussed. In the industrial world, great contribution to increasing CO {sub 2} emissions made by the economic growth factor has been offset by CO {sub 2} reductions resulting from energy conservation and fuel switching. The Soviet/East European and the developing worlds register increasing CO {sub 2} emissions. Different countries have different views of the key option to be taken in limiting CO {sub 2} emissions. Each of currently available CO {sub 2} reduction measures has its own difficulties, and none of them is able to provide a powerful means to solve global warming problems single-handedly. To begin with, it is essential to produce time to find truly effective limiting and/or adapting measures by slowing global warming as much as possible through comprehensive strategies which call for every possible effort in all the sectors. 83 figs., 92 tabs.

    As a series of the studies on the mechanical properties of spider threads, the effects of ultra- violet rays (UV) and water was investigated using drag lines of Nephila clavata (Jorougumo) and capture threads of Argiope amoena (Koganegumo). It was shown for the effect of water that (1) the drag line was contracted as soon as immersed in water (super contraction), while the capture thread was not so contracted and the viscid droplets attached to it were dissolved in water, and (2) the super contracted drag fine behaved like a capture thread with a j shaped load-draw ratio curve. For the effect of UV, it was found that (1) the degradation due to UV irradiation with short wave length was accelerated more than that with long one and (2) the degree of degradation for each wave length was governed by the integrated irradiation energy of UV. 9 refs., 8 figs.

    CO2 emission was quantified through the life cycle of a solar water heater to assess its environment impact. Although LCA (life cycle assessment) originally sums up I/O of all materials and energy through the whole life cycle of a product to examine environment impact, this assessment was carried out for only CO2. Calculation of CO2 emission assumed a natural circulating solar water heater of 200 l in effective hot water capacity, 2.78m{sup 2} in effective collecting area, and 0.5 in average annual collecting efficiency of total solar radiation, and an auxiliary city gas heat source for compensating insufficient heat quantity. The total CO2 emission in the life cycle of a solar water heater was obtained from an industrial association table assuming the life cycles of 10 and 20 years. CO2 emission was estimated to be 5407.1kg-CO2 and 10665.2kg-CO2 for 10 and 20 years, respectively. CO2 emission due to city gas was largest in the total CO2 emission in the life cycle. As a result, for reduction of CO2 emission due to a solar water heater, improvement of equipment efficiency was most important. 6 refs., 5 figs., 3 tabs.

    Primordial microbes that can function as photosynthetic catalysts are utilized in establishing a safe method for treating liquid or solid pollutant oxide wastes and household wastes and in activating vegetables` assimilation of gaseous wastes. A method for industrially accelerating their environment refreshing function and another method (the subject method) for measuring the effect are discussed. The technique of putting such methods to practical use is introduced, and the effectiveness of the said measuring is confirmed using empirically accepted rules. This method is based on the mycobiont/companion group method (EM method) that is advocated by Professor Higa of University of the Ryukyus. The group members form colonies with their symbiotic yeasts, lactic acid bacteria, actinomyces, leguminous bacteria, and nitrifying bacteria. Using this method, energy is industrially injected for acceleration and, simultaneously, the resultant effect is measured. The result of the measurement is next fed back so that the acceleration will be reflected. In this way, the effect of the primordial microbes that function as photosynthetic catalysts is confirmed and, secondarily, the basis is prepared on which element technologies will be developed to contribute to the enhancement of the multiplication of vegetables. 11 refs., 7 figs.

    The microbial industry can easily cultivate only the specific microorganism by introducing the closed reaction system and the sterile operation. When the superior bacteria is selected or it is created by the gene manipulation, therefore, it is not so much difficult that it is utilized for production. Since the water treatment is an open reaction system many microorganisms can join, however, it becomes to be important that how the necessary microorganisms, for example, the dephosphorylation bacteria etc. out of them are let fixed in the reaction system, and win in a competition with the other microorganisms, and in addition, are let display their functions stably for a long period. In this regard, in this paper, concerning to the issues that whether the dephosphorylation bacteria exists or not, how the behavior of dephosphorylation bacteria in the activated sludge should be clarified, what kind of behavior the dephosphorylation bacteria shows in the dephosphorylation activated sludge and so forth, grasping the population dynamics of microorganism, and furthermore, including the methodology to control it, is outlined. 31 refs., 2 figs., 1 tab.

    Effectiveness of the spectral method was confirmed for system interconnection type photovoltaic (PV) power generation systems, and PV array capacity determined in harmony with the power load was investigated. In this study, system interconnection type PV power generation systems with polycrystalline Si and amorphous Si PV cell modules were discussed. The output electric energy evaluated by the spectral method was compared with that evaluated by the conventional method only considering the cell temperature. Obtained results are as follows. For the polycrystalline Si, the differences between solar supply rates in summer evaluated by the both methods and measured value were less than 2%, which resulted in the accurate determination. For the amorphous Si, however, the difference less than 3% was obtained by the spectral method and that less than 11% was obtained by the conventional method. The spectral method provided higher accuracy. When constructing a system with large array capacity, it was found that the optimum design of PV power generation system can be performed using the spectral method with less array capacity than using the conventional method. 4 refs., 9 figs., 4 tabs.

    This report summarizes the result on selecting sites for large-caliber production wells, and landscape characteristic evaluation for simulation, based on the landscape survey on C candidate site for geothermal development. Field survey was made on landscape, plants and animals in the Kirishima Eboshidake area. It was clarified that this area has diverse flora including some rare species such as rein orchid and monkshood which are listed as endangered species. In addition, not a few epiphytes were identified. The zoological survey result showed that planted forests of evergreen coniferous trees which cover a wide range of the surveyed area, and peripheral grassland, scrub and natural forests provide good habitats for mammals such as sika deer and wild boars. On the other hand, no animal species in need of special protection were found. Geologically some traces of landslide occurrence in the past were detected in the northern part of the surveyed area relatively. As the survey result, some promising sites suitable for geothermal development were selected, which are judged to have a relatively small impact on natural environment and landscape. (NEDO)

    Investigations were carried out on effects of rearing environments such as light and bottom conditions on the ambicoloration of Japanese flounder. Young flounders were reared for 4 to 16 weeks in a water tank whose lid and bottom are made of colorless transparent plastic plates. Intensities of fluorescent lamps installed above and below the water tank were controlled. Sand and black resin plates were laid on the bottom of the rearing tank to discuss effects from change in the bottom properties. When the bottom of the rearing tank is made of a transparent plastic plate, ambicoloration has occurred to the flounders even if lights were irradiated from below at intensities of 1100 Lux and 7 Lux or even if the lights were cut off by a black resin plate. Even under a condition that a sandpaper is laid on the bottom to give fish feeling like contacting sand, the ambicoloration has progressed. When sandy transparent glass powder is scattered on the bottom, generation factor of individuals with ambicoloration has reduced to about a quarter. These results revealed that existence of a sandy material into which flounders can hide themselves is important for the effect on the ambicoloration of flounder, rather than existence of light irradiation or stimulation given something like sand. 18 refs., 4 figs., 5 tabs.

    The foraminifera, which is a biological species often used for the study of paleoenvironments, is taken up to discuss problems often encountered in the treatment of biological species in the study of paleoenvironments and methods to solve them. Changes appear in the chemical constitution of the shell of a foraminifer or the like for various physiological or ecological reasons. What is called the vital effect is the phenomenon of the systematic deviation of the shell chemical constitution from the environmental water chemical constitution due to metabolic reaction, and is supposed to reflect the integrated life cycle, growth rate, food preferences, microhabitat segregation, and the taphonomic process. In an experiment for establishing reliability for environmental proxies, it is found that a positive correlation exists between the Mg/Ca ratio in the shell of planktonic foraminifers and the culturing temperature/salinity. It is also learned that the Mg/Ca ratio is different among their species. Researches are now under way into elements that are in presence only in trace, such as Sr, Cd, Ba, Ge/Si, and into various organic substances. It is noted here that screening is required before some can service as environmental proxies. For this process, culture with specified environmental factors placed under control will be useful. 85 refs., 10 figs., 2 tabs.

    This paper describes target value setting as called for by the environment charter for the paper and pulp industry. An earth summit was held in Brazil, which adopted the Rio de Janeiro Declaration on environmental developments, the action plan Agenda 21, and the joint statement that demands development of forests in sustainable fashions and their preservation. The world's paper and pulp industries have set forth their attitude toward preserving the environment in this age of globalism of environment preservation. In particular, the environment charter announced by the leading Japanese paper companies has set various target values. In the area of establishing forest resources, the charter calls for planting trees over an area of 30,000 ha in foreign countries, and ensuring the import of broad leaf tree materials at 50% from the afforestation in foreign countries. In the area of environmental protection, the charter incorporates suppression of loads on the environment and total abolition of specific substances including chlorofluorocarbon. With regard to promoting energy conservation and utilizing unused energies effectively, the charter calls for 7% improvement per product over in 1991. For waste paper utilization, it is targeted that the rate of mixing de-inking pulps into newsprints be raised to 60%. Wastes reduction shall be achieved by reducing final disposition quantity by 40% from that in 1991. 1 tab.

    For the construction of houses that effectively utilize natural energy and impose less load on environments, an example of house building respecting environmental symbiosis is described. Reported herein are a heating system and the measurements of thermal environment in winter. In winter, the floor is heated by warm water from solar heat collectors circulating in pipes buried in downstair underfloor RC foundation. For the verification of the heating effect, comparison was made between the heater-provided southeast (SE) room and heater-unprovided northeast (NE) room, both downstairs.

    Assuming offshore location of thermal power plants by soft-landing artificial ground construction method, its effect on uneven settlement of facility unit group and its seismic behavior were studied. In soft-landing artificial ground, the total weight and buoyancy of a caisson body with interior space are balanced by controlling water level in a tank to reduce landing pressure. Artificial ground resists lateral seismic external force by friction with submarine bedrock. Settlement analysis and seismic behavior analysis were conducted by 2-D FEM. As a result, bottom RC honeycomb structure was sufficient to resist uneven settlement during construction even under fixed junction condition between units. In soft-landing artificial ground, the maximum acceleration was reduced to nearly 70% by aseismic base isolation as compared with conventional methods. In addition, its sliding manner in earthquake was different from that of rigid bodies, and the maximum stress acceleration transmitted to the bottom of artificial ground changed even under the same waveform. 4 refs., 13 figs., 4 tabs.

    It is recognized that similarity exists between world economics, crude oil price, production of crude oil by OPEC and non-OPEC countries, importation of oil by USA. environmental problems, of 1973, just before oil crisis, and those of 1986. World economics has been growing rapidly in later half of 1980s, though it is not so rapid as that just before the first oil crisis. Hovering oil price in recent years has been contributing to activate world economics in later half of 1980s, just like as directly before the first oil crisis. By considering such petroleum cycle, it was verified from various view points that petroleum market was entering into new phase of upward swing toward 1990s. 4 figs., 9 tabs.

    The new seeding method of MgO scattering particles based on a laser sheet method was developed, and the near-field structure of jet diffusion flame was studied. This method adds MgO particles (0.2-1.0{mu}m in size) produced by oxidation reaction as scattering particles through combustion of a Mg ribbon in a passage. Since this seeding method of scattering particles can add extreme-densely particles, this method is applicable to not only laser sheet visualization but also laser Doppler velocimeter and concentration measurement. In non-combustion jet formed over a contraction nozzle, coherent vortices are formed in the near field within nearly 8000 in Reynolds number, and the coherent vortices enhance mixing of fuel and air in the process of their linear and nonlinear growth. In the case over 8000 in Reynolds number, the small-scale short-lifetime coherent vortices are formed in the initial development stage of mixed layers, and the whole jet is dominated by irregular turbulent mixing after collapse of the coherent vortices. 14 refs., 8 figs., 1 tab.

    Interest has arisen for the sanitation and comfort of daily life. This paper explains a direction and other matters toward the 21st century, in retrospect of the history of housing sanitation from prewar days in the Ministry of Welfare and Education. Both urban and rural communities were in unsanitary dwellings and lives in prewar times. Various laws were established as measures against epidemics; and in 1927, the law for improving inferior housing land was enacted. In 1947, the Health Center Law was enacted, placing the sanitation for sewerage, wastes, etc. as its projects. In 1970, the `law for maintenance of sanitation in buildings` was enacted in the move beginning with the 1966 report by the Antipollution Council; the law resulting in extremely few problems such as the sick-building syndrome compared with the advanced nations today. Nowadays, changes being great in a mode of living, the Welfare Ministry is preparing various guidelines. Problems to deal with from now are numerous including a review on the law for maintenance of sanitation in buildings, the preparation of environmental air standard, and so on.

    The tropical forest regeneration technology research group of Kansai Electric Power Company and Kansai Environment Center has been performing the research and development of tropical forest regeneration technology jointly with Indonesia since fiscal 1992. The group was awarded with the Global Environment Technology Prize from Nihon Keizai Shimbun, Inc. As a result of stringent examination on 97 applications, being two times as many as in usual years, the group received high evaluation on the originality, reality and possibility of proliferation of its research, and impacts given to the societies. Two other groups were also selected. The achievements were reported by the representative of the group in the award commemoration lecture at the global environment economist summit held by the Nikkei press the same day. Conventionally, afforestation done with considerable efforts has often been lost by forest fires and slash-and-burn farming, whereas the present research aims at establishing a comprehensive afforestation technology considering social and economic aspects, and CO2 fixation. As one of the choices of flexible measures as a result of the effect of forests having been recognized in COP3, frameworks for utilizing the mechanisms of joint implementation and clean resource development were introduced. Ever increasing expectations are placed on the achievements of the present research works. (NEDO)

    This paper introduces a variable speed wind power turbine developed jointly by EPRI and US Wind Power Corporation. This wind power turbine has a wind velocity responsive construction in which generated alternating current power has the frequency vary with change in the shaft rotation speed. The specified performance calls for a cut-in of 4 m/s and cut-out of 29 m/s, wind velocity variable. The blades are made of laminated fiberglass, and the rotor has a diameter of 33 m, rotation variable. The tower height is classified to 24 m, 30 m, and 42 m. The blade pitch is controlled by a linear hydraulic cylinder, and the turbine is controlled by a microprocessor. The wind turbine has a system interconnecting control and data collecting system. Two induction three-phase generators are used. EPRI has calculated its power generation cost at 5 cents/kWh if wind blows at an annual average velocity of 16 miles per hour. This is nearly equivalent to the cost at new power plants. US Wind Power Corporation has disassembled 22 experimental models that have been in operation to investigate wear in the machines. Its economy is evaluated comparable with that for fossil fuel technologies. 1 fig.

    The purpose of this study was to examine the progress of development in the vicinity of Kibana district which was formerly surrounded by forests on the mountain and agricultural fields, but is currently a village in the rural-urban fringe transfigured by a large-scale educational city project after the removal of Miyazaki University. It was conducted by making a comparison with the relation between the development and the rise in land surface temperature. Changes in the environment were investigated using remote sensing technologies through preparation of a land classification map and a land surface temperature map by a utilization of a personal computer together with the obtained Landsat Thematic Mapper Data for the years of 1989 and 1990. As a result, it was found out that though the result of temperature comparison between 1989 and 1990 was 1.4[degree]C and 2.8[degree]C higher in 1990 at the lowest temperature and the average daytime temperature respectively, more difference was observed at land surface temperature in the land surface temperature map; and also, although evolution of mountainous areas to populated areas, overpopulation in residential quarters and expansion of populated areas, etc. were observed in the land classification map, agricultural and grass field areas augmented their image element number due to the unusual warm winter in 1990 and the inevitable rapid growth of grasses and flowers. 4 refs., 3 figs., 7 tabs.

    In Asian countries, the economic growth rate is extremely higher as compared with the world average, and accordingly a large growth in energy supply/demand and electric power supply/demand is paid attention to. Besides, at users` side, a fear is the worsening of the environmental problem which is brought about by a rapid increase in energy consumption. At suppliers` side, introduction/expansion of a large amount of foreign funds for rapid promotion of power source development become necessary so that supplying facilities catch up with the growth in demand. Moreover, dependence of the supply upon outside the area is becoming higher, and problems in safety guarantee are also becoming prominent. As for energy/power source mix in East Asian countries, the stable supply is basically considered as most important, and economical efficiency is also important including competition conditions among energies and potential raising of investment in supplying facilities. It is no exaggeration to say that the increase in the rate of coal which occupies most of the primary energy supply/power source in East Asian countries depends upon the progress of environmental harmony technology such as clean coal technology. 39 figs., 132 tabs.

    A survey was made to study possibilities of Japan`s cooperation in tackling energy/environment problems in Asian countries. In 1995 the GNP growth rate was 2.6% in the world, while it was 7.9% in Asia showing a rapid growth. With the accelerating industrialization and urbanization, energy demand is now over three times as much as that in the 1980s. This means increases in waste and environmental pollution. Especially, the use of firewood in non-electrified areas is a serious problem the same as the slash-and-burn farming and deforestation. Also relating to the production of electric power, it is inevitable to choose hydroelectric power and renewable energy in addition to fossil fuels. Therefore, the necessity is heightening of various technologies for it and environmental protection technologies such as coal cleaning. Local areas, where the population density is extremely low and the electrification cost is high, became victims of elecrification. There the power system should be shifted from the central supply system to the local distributed one. For it, it is necessary to recognize an importance of the distributed type renewable energy which is friendly to the environment. The paper outlined the state of each country and energy by policy and environment. 10 figs., 83 tabs.

    The paper studies a global CO2 recycling system which combines utilization of natural energy and CO2 recovered from combustion of fossil fuel. In the model, CO2 recovered at the place of energy demand is transported to the place where energy is produced, and from the CO2 fuels are synthesized by use of solar energy and transported to the place of energy demand. Facilities worth a large amount of money are required to transmit electric power generated by the photovoltaic power generation in the desert to the fuel synthesizing plant. Therefore, production of electrolytic hydrogen by the on-site power generation and transport by pipe may be considered. As a synthetic fuel being sent back by ocean transport, methanol is considered, and synthetic methane (LNG) can also be a candidate. CO2 is recovered as liquid carbon dioxide. Possibility of CO2 recycling is dependent on development of the desert solar base, as well as depletion of fossil fuel and price increase, CO2 penalty. It has still been difficult to say which of the fuel synthesis, CO2 tanker or securing of the solar base becomes a bottleneck. Entry of recycling fuels to the market will be possible in proportion to restrictions on fossil fuels, and evaluation of the system depends almost on the rate of energy arriving from the energy-producing region. 112 refs., 70 figs. 36 tabs.

    At the third Conference of the Parties to the United Nations Framework Convention for Climate Change (COP3) held in December 1997, the industrialized nations have agreed on development and proliferation of innovative technologies under international cooperation and transfer of environmental technologies to developing countries by expanding and strengthening CTI being the framework to be progressed spontaneously. Under the international strategic research project for global environment, NEDO has been promoting positively the research and development, whose support is urged to be expanded further in the future upon receiving the present agreement. Therefore, NEDO has performed the present survey in order to propose frameworks and measures for strengthening and expanding CTI. From among the policies and measures to be taken by the related countries based on the COP3 protocol, fiscal 1997 has performed review and new establishment of plans involved with execution of the items related to technology development, and surveys on action movements such as review and expansion of the measures, as the first stage.

    Telework is an effective work style using information communication without commutation, and ITS is an integrated traffic system such as advanced navigation. Effects of the CO2 emission reduction by these information communication systems were calculated as a trial. Reduction of CO2 4.06 million ton was obtained, which is equivalent to about 7% of the reduction target 56.5 million ton in Japan by 2010. For the items, were obtained 1.29 million ton (MT) by telework, 1.1 MT by ITS, 0.53 MT by the reduction of paper consumption/rejection using LAN, and 0.5 MT by the alternation of movements for international business using Internet (reduction of overseas official trips). In addition, were obtained 0.36 MT by the energy saving with enhanced efficiency of office environment using advanced information communication such as building management information systems, 0.25 MT by the electronic publication and newspaper for the reduction of paper consumption/rejection using electronic media such as CD-ROM, and 0.03 MT by the remote education and at-home education systems. The trial calculations were conducted only for these seven systems, and only for the direct effects using these systems. Accordingly, the result is only a part of the whole. These systems promote to realize a society with reduced environmental loads. 2 tabs.

    Experiments and studies are conducted for reducing along-the-road automobile running noise. In the study of noise generation due to tire vibration, it is found that the main mechanism of noise generation on a well-drained pavement is the vibration of tires. A calculation model is built for estimating the vibration of the tire belt from the characteristics of the road surface and the tire. In the study of air column resonance in the tread groove, a method is studied of measuring fluctuations in the sound pressure in the tread groove. Measurement is conducted, and it is found that the generally accepted explanation, in which air column resonance is attributed to tread vibration generated upon collision of the tire with the road surface, needs further study for substantiation. In a model experiment, it is found that air column resonance hardly occurs on a well-drained pavement. In the study of hydroplaning, it is found that, even when the total volume of the tread longitudinal grooves is the same, the hydroplaning performance tends to improve when the groove arrangement and crown curvature are proper.

    This research was made for investigating the impact of geothermal development on hot spring, ground water level and spring water by drilling 3 investigation wells N9-AY-3, N9- AY-4 and N9-AY-5 in Akinomiya district. Some research items for hot spring showed slight fluctuation until 1997, however, those showed no fluctuation due to drilling of the 3 investigation wells in fiscal 1998. These results suggest that drilling of the investigation wells has no effect on the spring and quality of hot water in Akinomiya district. Drilling of N9-AY-4 well is carrying out continuously after Sept. 1998. Fluctuation of ground water levels was dependent on precipitations, however, drilling of the 3 investigation wells has no effect on the ground water level. These results suggest that drilling of the investigation wells has no effect on the spring of hot water in Akinomiya district. Every research item for spring water showed relatively slight fluctuation stably. These results suggest that drilling of the investigation wells has no effect on spring water in Akinomiya district.

The energy consumption under the maximum load is approximately 6723MJ/h for cooling, 5379MJ/h for heating, 4613MJ/h for hot water supply, or 1009kW in wattage. The cogeneration system is to have two 100kW city gas engine generators, whose output will be supplied only to common use facilities and heat source rooms in the high-rise building, for corridor lighting, elevators, and pumping. Heat in the gas engine exhaust and waste cooling water is recovered and utilized for hot water supply and heating for the individual residences. Simulation results show that there is an approximately 7.2% saving on energy and, relative to environmental protection, a reduction in CO2 emission of approximately 9% a year. 2 refs., 4 figs., 1 tab.

    This effort exerted in cooperation with the Philippines aims to solve problems related to water resources such as stable supply and pollution of water through developing a waste water treatment/water reuse system which is easy to operate and maintain, and low in price. The ultimate goal includes (1) the construction of a waste water treatment/water reuse system comprising an anaerobic reaction tank and activated charcoal absorption tower, easy to operate and maintain, and low in price, (2) the employment of goods procurable in the Philippines, the goods including carriers for use in the anaerobic reaction tank, microbes for use in both aerobic and anaerobic reaction tanks, and activated charcoal for use in waste water reutilization, and (3) the establishment of optimum operating conditions for the waste water treatment/water reuse system by use of a pilot plant and the transfer of operating and managing techniques to the Filipino counterpart. In this fiscal year, investigations are conducted to disclose the actualities of waste water treatment and water consumption by primary industries in the vicinity of Laguna de Bay, and the waste water to be the object of study and the place of pilot plant installation have been selected. Also conducted are investigations into the carrier, microbe, activated charcoal, etc., for use in the anaerobic reaction tank. (NEDO)

    In order to investigate the causal relation of change in vegetation status with the power station after starting the operation, pine trees in the surrounding area were studied in tree ring characteristics. The sampling was made at six stands ranged from the Tohhoku district to the Chugoku district. Pinus densiflora and P. Thunbergii were 0.1 to 16.2mm and 0.05 to 9.05mm, respectively, in tree ring width. They were, in frequency distribution, both a logarithmic normal distribution with 1.05 to 1.50mm in mode. Their frequency distribution being a logarithmic normal distribution, along with advance in years thereafter it transfers to a normal distribution, then to a logarithmic normal distribution, then to an L-shaped distribution. Pinus densiflora and P. Thunbergii were 6.5+-3.5mm and 6.5+-2.5mm, respectively, in maximum tree ring width, of which the appearance ratio was high in trees, 4 to 12 years old. While the minimum tree ring width appears, when the tree is very young in age and in specific calendar years during its second half of life. As for the time series of tree ring width, it, small when one year old, continues to enlarge along with advance in years until about ten years old, attains the maximum and, after then, diminishes along with advance in years. 6 refs., 7 figs., 3 tabs.

    An investigation was conducted with the aim of elucidating the foundations for effective utilization of environmental pollutants or unused resources which are likely to be causal substances of environmental pollutants, as resources, using biotechnology. Composting of agricultural waste, production of microbial mycelium proteins and microbial fermentation materials were suggested as main examples of effective utilization of unused resources by microorganisms. Selection of active microorganisms in the livestock waste, clarification of the mechanism of action and the establishment of treatment conditions are essential to new developments in this field. In the field of marine products industry, it was pointed out that the recycling of waste using microorganisms and enzyme treatment is the most promising approach to the effective utilization of resources. In the field of food industry, applications as the culture media for mushrooms, for enzyme production and for the production of physiologically active materials as well as fuel were clarified. Was also pointed out the significance of studies on the microorganisms and enzymes in resources containing cellulose, hemicellulose and lignin, and the waste from these resources, lignocellulose. Were also proposed the composting of household waste, methane fermentation, and fermentative production of organic acid and hydrogen from waste. Possibility and significance of fermentative production of organic acid from sewage sludge were suggested. 314 refs., 46 figs., 33 tabs.

    The research is conducted in cooperation with Industrial Technology Development Institute of the Philippines, and aims to solve water related problems such as unstable water supply and water quality pollution though developing a waste water treatment and recycling system which is easy to operate and maintain, low in cost, and usable in the Philippines. Fiscal 1998 is the second year of the project. Statistics are studied about the load that each industrial branch imposes on water for its pollution, and it is found that food manufacturers, paper pulp mills, and fiber dyeing plants are heavily responsible for water pollution. A method consisting of single-tower UASB anaerobic treatment and activated sludge treatment is applied as a water treatment process to Ram Food Products Corporation, and its optimization is studied. A removal rate 60% is achieved after a 12-hour treatment period at a COD (chemical oxygen demand) rate of 8g/liter/day. A method consisting of coagulating sedimentation and activated sludge treatment is applied to the waste water from a Solid Mill Corporation dyeing plant, when it is found that the water after ultimate treatment is almost colorless and that COD is 76mg/liter and BOD (biological oxygen demand) 13mg/liter, and these suggest that the waste water is recyclable. Since it is low in COD removing rate, the application of anaerobic treatment to high-concentration water after washing is not appropriate. (NEDO)

    For the purpose of securing water stably and preventing water pollution in the Philippines, R and D were carried out on a wastewater treatment and water reclamation and reuse system which is easy to operate and maintain and low in cost through the research cooperation between the Philippine Industrial Technology Development Institute and Japan. According to the survey result of statistical data concerning water pollution load structure by industrial wastewater classified by the industry in the Philippines, enumerated are the food manufacturing industry, paper pulp manufacturing industry, and the textile dyeing industry as those greatly affecting water pollution in BOD exhaust and wastewater, etc. Consequently, with Ram Food Product Co. of vegetable processing and Solid Mill Co., of textile dyeing as plants to be studied, a wastewater treatment test was performed in a laboratory scale. From the result of the test, the pilot plant was basically designed to have 'anaerobic + aerobic treatment + tertiary treatment' for the treatment process, with an one-tank type UASB method used as the anaerobic treatment, with a sand filtration + activated charcoal treatment as the tertiary treatment, and with the cost effectiveness for water reuse set to be examined.

    For the purpose of solving environmental problems caused in association with the increasing industrial activities in the Asia-Pacific region, the construction of a research network is being advanced aiming at promoting exchanges with researchers of other countries and activating information exchanges. Investigators were sent overseas to grasp the present situation, and researchers participated in a symposium on the APEC environmental technology cooperation for mutual understanding and personal interchange. In the overseas survey, visits were paid mainly to national research institutes and universities in India and Thailand. Positive approval was obtained on the construction of the ETERNET APR (Environmental Technology Research Network in the Asia-Pacific Region). In the symposium on the APEC environmental technology cooperation held in Nagoya, researchers participated mostly in the second session and made earnest discussions with researchers from other countries. The necessity and importance of the network was emphasized. Countries which participated the symposium have problems common to each, and it was greatly significant to meet together and discuss together. The environmental problem is on a global scale, and it is necessary to make close exchange/interchange of information/opinion on a long term basis and to tackle it in the whole Asia-Pacific region. 3 tabs.

    With an objective to give some suggestion to the water resources policies for the future Japan, a comparative study was made on the water resources development policies in Japan and the water resources policies in the state of California, U.S.A. The study on Japan has been proceeded empirically based on specific data with regard to the development of electric power policies from the prewar to postwar times when the governmental electric power control was changed to incorporation of the nine electric power companies. The change may be identified from viewpoints of both profit and ideology. Noticing the `public corporations` established one after another for social capitals before and after the establishment of the Liberal Democratic Party, their relation with the water resources development policies was pursued in terms of actual proof and political science. The identity of the public corporations established in and after 1955 stands on the premise of free economy, rather than the controlled economy. This paper positions the water resources development policies in a broader context as the national land plan, and considers the problems that are expanding from flood damages, dam construction, industrial complex construction to environmental problems around the water. Comparative discussions on the Tone river system and the Colorado river system were left as the future assignment.

    The general analysis/assessment method of a fossil fuel cycle was studied. Seven kinds of power generation plants such as LNG cycle and coal cycle ones, and four kinds of transport and treatment systems of recovered CO2 such as ocean and underground systems were studied as case studies on life cycle analysis. As data necessary for life cycle analysis, the database was constructed which stores the facilities and operational energy required for a total energy system from mining of fossil fuel to treatment of recovered CO2, and the quantity of environmental waste such as CO2 emission. As a result, the decrease rate of energy balance defined as ratio of input energy to power plant output was estimated to be 14-43% and 20-60% in LNG cycle and coal cycle, respectively. Even if the recovery rate of CO2 in power plants reached 80-90%, reduction of total CO2 emission was limited to only 20-40% because of CO2 emission during mining, liquefaction and transport of fuel. 168 refs., 48 figs., 102 tabs.

    This survey was conducted to estimate effects of drilling of geothermal exploration well on the environment, aiming at grasping the present state of environmental elements before the survey/development. As a result of the literature survey, the following distribution were confirmed in the fauna: 5 orders 10 families 19 species in the mammalia, 10 orders 25 families 73 species in the aves, 1 order 3 families 6 species in the reptilia, 2 orders 6 families 9 species in the amphibia, and 17 orders 179 families 719 species in the insecta. In the flora, a distribution of 132 families 670 species was confirmed. The results of studying the above indicated that in the fauna, there were 10 species such as antelope as valuable animal in the area surveyed and that it is necessary to pay much attention to the environmental preservation of the habitat for those animals in the well drilling associated with geothermal survey. In the flora, the 13 valuable animals selected as animal having a fear of extinction in the 'plant-version red list' were confirmed in the area surveyed and the periphery. Further, as to the plant colony, there are no important colonies in terms of preservation. In well drilling, important things are efforts exerted to restore to the original state of the area altered, prevention of the washed-away of mud water, etc., and efforts exerted to preserve the environment of vegetation.

    A survey was performed on the current situation in the Kuwanosawa district in Akita Prefecture to identify influence on the surrounding environment due to drilling of geothermal structure testing wells. The survey on animals covered mammals of five divisions, 10 families and 19 species, Aves of ten divisions, 25 families and 73 species, reptiles of one division, 3 families and 6 species, Amphibia of two divisions, 6 families, 9 species, and Insects of 17 divisions, 179 families and 719 species. Precious animals of a several species including black salamander were identified. In the plant survey, 132 families and 670 species were identified, with several species listed as the precious plants. In the survey of hot springs, those at three locations were all high-temperature hot springs at as high as 53.8 to 96.9 degrees C. Amount of discharge, pH and electrical conductivity differ largely by the hot springs. The hot spring in Takamatsu did not show large variation throughout the survey period. The Ogura Inn at Doroyu Spa has small variation in pH and hot spring temperature, but large variation in the amount of discharge and Al{sup 3+} concentration. Correlation was recognized between hot spring temperature and amount of discharge, between hot spring temperature and anion, between amount of discharge and electric conductivity, and between amount of discharge and anion.

    A study was conducted on how to fix CO2 in the ocean using coral reefs. Coral reefs have extremely high primary productivity ( production quantity of organic matters by photosynthesis) and are expected to be resources to fix CO2 when the quantity of photosynthesis exceeds the quantity of CO2 emitted in association with formation of calcium carbonate skeleton. If organic substances produced in coral reefs are well carried into the open sea, those are settled down on deep beds, which enables the storage into the ocean. At the coral reef floating in the ocean, it is not very deep inside and the seawater stays there, but it has a steep depth outside. By the numerical calculation, an examination was made on how the waterflow changes when making the flow path of seawater between the inland sea and open sea. From the actual calculation of an atoll, it was found that seawater comes in and out from the open sea to the inland sea near the opening of the atoll in accordance with the high tide and ebb tide, but the water stays at the deep bottom of the atoll. When installing a channel with a 10m depth at the portion where the water flows softly, the seawater was actively exchanged. 6 refs., 4 figs.

    In order to evaluate presence or absence and extent, if present, of the effects of drilling a geothermal well, changes in flowing-out rate of hot spring and others were surveyed at the hot spring resorts in the Kuwanosawa area and its peripheries, extending around 18 km{sup 2} area in the mountains approximately 20 km to the south of City of Yuzawa, Akita Pref. Three sites were selected; the hot spring resort of Takamatu, a hot spring resort at the foot of mountain, and another hot spring resort near the dry riverbed of the Takamatu River, where hot spring spontaneously flows out in all of these sites, from the 1,500 m deep boring at the first site, and in the area where steam is gushing out in the second site. The surveyed items were rate of flowing-out, temperature, electroconductivity, pH and various ion concentrations of the hot spring, and precipitation. The survey was conducted 19 times from August 9, 1999 to July 12, 2000. For the effects of drilling the geothermal test well and drawing-up the hot water, some surveyed items changed significantly in these 3 resorts. These changes, however, largely result from seasonal reasons as well as conditions within each hot spring well, and not from the drilling of the geothermal test well N11-KN-1 and drawing-up of the hot water.

Outline of global warming problems and developments of international conferences. 2. Factor analysis of past CO{sub 2} emissions. 3. Measures to limit global warming. 4. Limitation measures for global warming and prospects for CO{sub 2} emissions. Analyses are made by country, by region or globally. For example, in order to establish measures to solve the global warming problem as an international issue, it is most important to establish the target criteria to control emission of greenhouse gases like CO{sub 2}. Namely, most important is to determine the criteria and partial charge of each country. These will exert a large effect on each economic activity. There are big differences among countries in the gas emission up to the present from the past. Effects of the gas emission are also different among countries. Moreover, countries are different in their development stages. All these differences are an important subject in judging international fairness. 91 refs., 91 tabs.

    This study have dealt with the issues of how the policies of environmental and natural protection should be shaped in a democratic society, and what the optimal legal systems should be for realizing the policies. We have analyzed these issues from the following three points of view ; the first one is the legal philosophical issues of justice and moral values among individuals and organizations. Secondly, we analyzed the optimal deterrence system of organizations for pollution controls, etc. We studied crimes and illegal conducts by organizations and corporations themselves, and their employees under the principal-agency model. Third, we looked at the legal system itself and the foundations of environmental issues from the legal-philosophical aspect. Fourth, we analyzed how the social decision-makings on the environmental protection were produced, using the public choice theory. (author)

    An application is reported of the LCA (Life Cycle Assessment) concerning reusable beer bottles (volume: 633cc). Data were collected for examination covering the four stages of natural resource acquisition, bottle production, beer filling and packaging, and distribution and consumption (with the stage of waste management being excluded because of inadequate data). Examination was made of changes brought about in the total energy consumption by varying the five parameters, that is, the number of usage of bottles, transportation distance for empty bottles, cullet ratio in glass manufacturing, transportation distance for cullet, and the bottle weight. It was found that the total energy consumption decreases with an increase in the number of usage of bottles, that an increase in the cullet ratio and a decrease in the bottle weight are effective in decreasing the total energy consumption, and that there is an energy-wise disadvantage when empty bottles are transported over a longer distance without an increase in the number of usage of bottles. 4 refs., 6 figs., 1 tab.

    This paper describes the main features of flood plains and fish production related to agriculture in the vast inland water areas of Bangladesh. The inland fisheries have been an important source of animal protein and provided employment opportunities for rural Bangladeshies. Generally the fishermen's economic conditions are below the poverty line in this country. Fishi production in the inland water areas are not met to the basic needs of the people on a sustainable basis. While inland fishery is important for business as well as for people's livelihood, it is not usually managed appropriately for resource conservation and environment. Fishery policies and planning have to be undertaken for comprehensive long-term perspective in order that agricultural and other sectors would not contaminate the environment. (author)

    Discussions were given to reserve global environments on reducing dependence on fossil resources and more effectively utilizing wood resources. Economically utilizable amount of wastes from lumbering factories reaches about five million tons annually. Discussions were made on a ligno-bioprocess that uses these wastes. The current quantitative production efficiency of cellulase by means of bacterial breeding is very high. A problem is production of ligninolytic enzymes, to which application of the recombinant DNA method is indispensable. Combination of steam explosion with biological decomposition or the organosolv process is an effective method for lignin decomposition. Decomposition of cellulose by using the ultra critical water method is worth noticing. With respect to hemicellulose utilization, production of cellulose derivatives, biodegradable polymers and oligosaccharides would be conceivable by means of esterification and etherification. Vanillinic acid, adhesives, resins and lignin-based polymer materials could be manufactured from lignin. Material cost for these products accounts for about 35% of the product price, thus making the lignochemicals promising commercial products. 301 refs., 71 figs., 39 tabs.

    Exchange of personnel among foreign research organizations is significant for promoting research and development to create new research fields and to build new technological systems for the purpose of solving global environmental problems. For this purpose, researchers were sent/invited to/from international conferences and international symposiums related to global environmental technology and exchange of personnel with major foreign research organizations and universities was conducted under the cooperation of RITE and RITE-related researchers and related academic societies. Based on short-term invitation and sending of researchers as well as the feasibility study of researcher exchange, researchers were sent/invited on long- and mid-terms. As a result, exchange of personnel engaged in the latest research in Japan and overseas could be promoted. It was found that various researches are being conducted abroad in basic areas of global environmental technology. Since they are closely related to the research and development of industrial technology contributing to global environmental preservation promoted by RITE, it is important to establish a more efficient exchange system of researchers in the future. 91 refs., 38 figs., 14 tabs.

    In the subject model, a system was structured in which reproducible energy was classified into five kinds and in which recovery of CO2 from fossil fuel, processing technique and types of land utilization were generally handled together with the supply/demand of food. As a result of the analysis, it was pointed out that, although the supply of biomass energy by fuels based on agricultural waste and forestry management was hardly dependent on the structure of food supply/demand and CO2 control, the energy supply was extremely low in economical efficiency and unreliable in the future; that the CO2 recovery and its processing techniques, if the emission control was provided, would not be effective until the latter half of the next century, and accordingly, the stability of these techniques and their effects on ecosystem, for example, were necessarily investigated fully; also that, as dependency on coal is going to be high from the latter half of the next century, the techniques derived from there will be expected, and so on. The detailed preparation of energy flow was considered necessary from now on. 12 refs., 16 figs., 7 tabs.

    The new energy visions are drawn for Town of Naie, Sorachi-gun in Hokkaido, where the industrial sector (manufacturing industries) consumes more than 60% of the total energy consumption. By energy type, oil and others account for 80%. When arranged in the order of expected recoverable quantity, the new energies for the town include utilization of solar energy, photovoltaic power generation, wind power generation, and utilization of wastes, biomass energy (agricultural products) and snow energy. The basic guidelines for introduction of new energies are for health and welfare, clearing and utilization of snow, environmental education and bringing up talented persons, supporting the related entrepreneurs, and integration of new energy with promotion of energy-saving movement. The priority projects the town plans to promote include utilization of biogas and temperature-differential energy for the town's water purification center; foundation of the Naie eco-school; and drawing conceptions for utilization of underground heat, utilization of low-temperature and snow/ice energy, co-energy around the spa of Naie, and mega-solar and eco-park at the Sorachi housing complex.

    The above was conducted by Research Institute of Innovative Technology for the Earth (RITE). Worldwide collaboration is mandatory for the settlement of environmental problems for the earth, and RITE is positively promoting its interaction with research institutes abroad. In fiscal 1998, it sent research teams to government organizations and research institutes in Europe and America for studies there. A study in Europe involved the preparation of chemicals from CO2 by virtue of novel biotic reactions, and RITE's microbial molecular function laboratory plans to start a leading study in fiscal 1999. In relation with environmental impact reducing technologies using sunlight-aided photocatalysts, visits were paid to three research institutes in America. RITE itself has developed a powdered semiconductor catalyst and is engaged in the study of producing hydrogen by decomposition of water using solar energy. Concerning the production of saccharides out of farm wastes remaining unused, researches were made into the feasibility of joint studies with some advanced research institutes in America. Discussions were made about the performance- and stability-related improvement of enzymes usable for the decomposition of biomass, the analysis of biological environmental circumstances that substance yielding microbes find themselves in under anaerobic conditions, etc. (NEDO)

    A survey was conducted about what consciousness city inhabitants entertain toward farmland in their living quarters or in the vicinity thereof and what evaluation they have of such farmland as compared with the green zones or open spaces. The survey was conducted by soliciting answers to queries from the non-farming urban population in the city-planned area, where there is co-existence of urban living quarters and farmland, and in the out-of-city-plan area, where such co-existence is realizing, in the eastern part of Fukuoka City. As the result of the survey, it was learned that the most important role they expect of the farmland in the vicinity of the urbanized living quarters is that of a pastoral landscape or a green open space, that the farmland has come to occupy a place in the inhabitants` residential environments, that, concerning the utilization of the farmland, they eagerly want to directly purchase produce of agriculture from it or to enjoy it as a citizens` farm usable for recreation, that inhabitants with longer stay therein want more earnestly the buildup of living environments including the farmland. When the answers to queries are broken down by the purpose of land utilization, it is learned that the inhabitants love farmland next to a tree-covered zone, with city parks left to enjoy the third place. 5 refs., 18 figs., 5 tabs.

    The paper studies a global CO2 recycling system which combines utilization of natural energy and CO2 recovered from combustion of fossil fuel. In the model, CO2 recovered at the place of energy demand is transported to the place where energy is produced, and from the CO2 fuels are synthesized by use of solar energy and transported to the place of energy demand. Facilities worth a large amount of money are required to transmit electric power generated by the photovoltaic power generation in the desert to the fuel synthesizing plant. Therefore, production of electrolytic hydrogen by the on-site power generation and transport by pipe may be considered. As a synthetic fuel being sent back by ocean transport, methanol is considered, and synthetic methane (LNG) can also be a candidate. CO2 is recovered as liquid carbon dioxide. Possibility of CO2 recycling is dependent on development of the desert solar base, as well as depletion of fossil fuel and price increase, CO2 penalty. It has still been difficult to say which of the fuel synthesis, CO2 tanker or securing of the solar base becomes a bottleneck. Entry of recycling fuels to the market will be possible in proportion to restrictions on fossil fuels, and evaluation of the system depends almost on the rate of energy arriving from the energy-producing region. 112 refs., 70 figs. 36 tabs.

    Tire/road noise and the running performance were studied. Test were conducted using drum testing machine. If kinds and frequencies of tires are different, noise radiation characteristics are also different, and the degree of the difference are more remarkable in tires of passenger cars than those of large sized cars. There is also observed special frequency noise caused by natural vibration of tires. Noise increases when there are translots in tires, it decreases when having the translots had angles. In hydroplaning, tires which had translots installed inclinedly generate less noise. The sound absorbing rate of the pavement using dense particle asphalt-concrete mixture is low, below 0.2, but the drainage type pavement (three kinds) showed high sound absorbing rates (0.4-0.7) in each kind. Noise reduction by the drainage type pavement was seen also in the engine type noise. Further, prediction of noise propagation was possible to a certain extent using the Allard model. As to lock braking force coefficients on the wet road, there are no definite differences between roads in terms of passenger cars, but the coefficients are higher in the drainage type pavement than that using the dense particle asphalt-concrete mixture in terms of large sized cars. On the dry road, those in the use of dense particle asphalt-concrete mixture are the highest. 3 refs., 96 figs., 11 tabs.

    The follow-up was conducted of the project for supporting the introduction of the environmentally friendly type coal utilization system and demonstrative project on simplified desulfurization facilities which were carried out with the aim of reducing environmental loads associated with the coal utilization in Thailand, and the FY 1999 results were reported. As to the follow-up project, survey was made of the operation state of the simplified flue gas desulfurization (FGD) system, and at the same time, the following were carried out at the time of periodic inspection/repair: examination of/guidance for maintenance, and welding repair guidance for the corroded spots of flue. Thai Union Paper Public Co. (TUP), which had already acquired ISO14001, is a model company earnestly tackling the environmental improvement. Approximately 400 persons per year visit to see the FGD system. About 3 and a half years have passed since the FGD system started operation. Scaling of gypsum, etc. and corrosion at some part were seen, but the whole plant is in smooth operation. As a result of the analysis, purity of the recovered gypsum was approximately 90%, and therefore, that is very usable as raw material of cement. The progress of corrosion and increase of corroded portions were hardly recognized as compared with those in the previous fiscal year. (NEDO)

    This R and D is aimed at promoting reduction in environmental loads by waste, etc. and reutilization of waste, etc., and at developing environmental technology such as recycling contributing to reducing road traffic noise. Studies were made on operation conditions of material separation in the bottle state and flake state, color separation, washing process, etc. Moreover, tests were conducted on comparisons of performance of shredders with different functions. Running tests of 100,000 times were conducted to confirm effectiveness of durability of the paved road with used papers. Measurement of hardness of the resin using the sol-gel method and coating experiment using organic dye were carried out to study the membrane effect speed and flaw resistance of coating of coloring bottles. Gasification of shredder dust and separation of nonferrous metal and glass were conducted to get the basic data. As to FRP bath tubs, the ratio of glass fiber and plastics was studied and western tiles were trially manufactured. Further studies were made of removal conditions of noncombustibles, chlorine and sulfur content, and reaction conditions of alkali additives including kind, quantity and addition method. 166 figs., 132 tabs.

    For the state-run plant of Pakistan Steel in Pakistan, an investigational study was conducted on energy conservation and reduction in greenhouse effect gas emission. In the project, energy conservation technology on the following was tried to be introduced: coke oven coal moisture control (CMC) equipment, sintering cooler waste heat recovery equipment, blast furnace hot stove waste heat recovery equipment, blast furnace pulverized coal injection (PCI) equipment, blast furnace top pressure recovery turbine (TRT) equipment, and hot strip mill heating furnace regenerative type burner equipment. Further, in the project on environmental improvement, studies were made on coke oven environmental improvement and blast furnace cast house dust collection. The results of the study indicated that economical effects of the energy conservation project were considered as low because the unit price of energy of Pakistan Steel is low. However, substitution of the low-priced domestic coal for the imported coal has a good effect, and energy conservation in the TRT power generation and by the regenerative type burner produces a highly economical effect. Therefore, Pakistan Steel also agrees to positively promote the project. Moreover, concerning the environmental improvement project, it was considered that the necessity of the project is high in the relation of the coke oven aimed at reducing emissions of toxic substances.

    Pursuant to the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol, studies are conducted on a district cogeneration station for Radom City, Poland. Using the annual load pattern of heat supply, cogeneration will be built only for the amount that covers utilization factors not lower than a specified level, and the shortage in winter when the load is heavy due to demand for heat will be dealt with by the existing hot water boilers. Daily change in load is to be covered by a new, additional boiler which will bear 20% of the whole output. The system is a natural gas fired turbine cogenerator, and hot water is supplied by a waste heat recovery boiler. Cogeneration will cover 80% of the annual heat supply. As for heat supply capability, it is set at 72MWt with the additional boiler taken into account, and 35MWe is to be generated. Heat efficiency will increase to be higher than 80%, coal consumption will decrease, and 28,117 tons/year in terms of oil will be saved with the increase in natural gas consumption subtracted. CO2 reduction will also be as large as 206,000 tons/year, decreasing air pollutants. Provided that 4.336-billion yen for facilities are financed by Japan's environmental yen loan, Poland's National Fund, and Radom City's own fund, IRR (internal rate of return) on investment will be fairly good at 10% in 30 years of operation. Investment will be recovered in nine years and there is no problem in cash flow. (NEDO)

    This paper indicates that the relationship between toxicity and biological activity of environmental hormones such as dioxin and their chemical structures may be predicted by using parameters (physical quantity) derived from the chemical hardness conception. According to this conception, softness and hardness of molecules are important in addition to electron receptivity and donation properties of molecules. Soft compounds facilitate electrons to migrate. Chlorine displacement of dioxin skeleton to 2nd, 3rd, 7th and 8th orders softens the molecules and displacement to 1st, 4th, 6th and 9th orders hardens them. The toxicity and biological activity of the environmental hormones cannot be explained only with the fit model of key-keyhole with the counterpart they act on (receptor). The softer the chemical hardness, the greater the toxicity and biological activity. Development has been made on an absolute hardness versus absolute electrical negative activity diagram to learn electron structure of molecules. This diagram indicates that the toxicity of dioxin depends more strongly on the chemical hardness than the strength of the electrical negativity, and the softer the hardness, the stronger the toxicity.

    The representative result as the global environmental problems caused by chemical substance is the ozone layer depletion of the stratosphere by chlorofluorocarbon (CFC). The regulation of the CFC began in 1989 based on 'Vienna Convention for the Ozone layer protection' (1985) and 'Montreal Protocol on Substances that Deplete the Ozone Layer' (1987). Production and consumption of CFC, tetrachloromethane, methylchloroform and halon have already been aborted, and the regulation of HCFC and bromomethane were also began to turn to the abolition. The increase of atmosphere average concentration such as CFC and methylchloroform has already blunted in such the international regulation. The chloride concentration of stratosphere from substance of the ozone layer depletion would reach a peak soon, and was prospected to be reduced after then. It is expected to drop to previous level before the South Pole ozone hole appeared after the middle in the twenty-first century. Finally, the future prospect of the gentle chemistry in the environment is described. (NEDO)

    Global environmental problems are growing quite serious in developing countries, yet they are requested to properly deal with them without making light of sustainable development, for which international cooperation and diffusion of technologies for the development of environmental technologies are mandatory. Japan, utilizing what it learned from pollution within in the past and making the best use of its technologies and knowledge for environmental improvement in developing countries in Asia, has been hosting since fiscal 1997 a function of Environmental Technology Research Network in the Asia-Pacific Region function. In fiscal 1998, a fifth international symposium was convened at Science City Center at the foot of Mt. Suzuka on November 26 and 27. The central theme was the development of environmental technologies and international cooperation for developing nations, and the event attracted 180 participants from inside Japan and abroad. A number of concrete themes came out of working groups on water quality, air quality, and energy/waste, which concerned the drafting of propositions for international collaborative researches. As for researches abroad, four typical Malaysian institutes were visited. (NEDO)

    The paper developed an analysis method of the energy supply/demand structure of city and compared the conventional city and a city considering energy conservation. An energy supply/demand flow chart was newly proposed. From this flow chart, `energy sustainability ratios` was proposed as a new index for comprehensively evaluating two elements of the energy conservation by load reduction and heightening of energy conversion rates and the utilization of waste heat and renewable energy. A method for analysis of the energy supply/demand structure of city was developed including daily supply/demand patterns in the area where individual equipment in every residence/building correspond to the energy supply and the area where centralized energy systems such as district energy supply correspond it. From the developed analysis method, analysis was made of a newly developed city with a 0.6 million population in terms of the conventional city and energy conservation city, to clarify the present energy supply/demand structure of city and to express it in an energy flow chart. At the same time, validity of the analysis method and evaluation indexes were confirmed by comparing the conventional city and energy conservation city. 15 refs, 27 figs., 17 tabs.

    An environmental liability act was promulgated in the European Community where the regulation on air, water, soils and foods, and the liability provisions are increasingly tightened. This paper introduces the Conditions in Germany'' for the circumstances thereabout as seen from the insurance company point of view, using an extract from the presentations at the lst International Safety Engineerings Conference. In Germany, the consciousness to the problem of Altlasten'' (inadequate disposition areas) has been heightened since about 1983. This has made the problems of soil and ground water contamination handled in more advanced ways, whereas the criterion values are not fixed but incessantly revised downwards, causing a situation embarrassing for insurance companies in how to handle liabilities of unspecified number og parties on the pollutions accumulated over many years. The new environmental act is unified under one common concept from the water quality control act to the gene technologies act. For instance in the gene technologies act enforced in July 1990, all the related operations must follow the intentions of the law makers, and are subject to statutory regulations. Liabilities must be fulfilled on any damage that even operators and scientists were not able to be aware of.

    Discussions were given on the new energy vision at Ueki Township in Kumamoto Prefecture. The total energy demand in Ueki Township is 898 x 10{sup 7} Kcal. of which about 44% is accounted for by the transportation department, 34.7% by the industrial department, and 21% by the consumer department. The total available regional new energy amount is estimated to be 52.1 x 10{sup 6} kWh/year, which is consisted of stockbreeding wastes energy at 44.1%, solar energy power generation at 33.2% and solar heat utilization at 22.6%. Introduction of wind energy was judged impracticable. The new energy introduction plan calls for introduction of solar energy power generation for lighting and air conditioning of the diamond shaped nursery school, the Yamamoto nursery school, the Ueki Township office building, the multi-purpose sports center, the Ueki Hospital operated by the national health insurance, the multi-purpose health and welfare center, Yoshimatsu Sports Park, and Tahara Sports Park.

    With objectives to realize a recycling society and protect global environment, development will be made on solidified fuel using waste papers and waste plastics as the raw materials. This paper describes the achievements in fiscal 1998. To develop a pretreatment technology, analyses and discussions were given on functions required to separate and remove such foreign materials contained in combustible wastes as metals, ceramics, and glasses, and to pulverize the combustibles removed of non-combustible materials. A bench-scale testing equipment of 0.5 ton per hour was installed and operated on a trial basis. In order to identify dechlorination properties of waste papers and plastics to develop a dechlorination technology, basic dechlorination and pyrolysis tests were performed by using cellulose powder and polyvinyl chloride powder as raw materials. Detailed design, fabrication, installation and trial operation were carried out on a dechlorination device to be assembled into the bench-scale testing equipment. Investigations were given on the actual status of discharge and collection of waste papers and plastics to discuss the practical use of the fuel. The current status of discharge of general wastes was identified, which will be the object of the container package recycling law. The range of LCA was discussed, and technical data of wastes electric power generation were collected. (NEDO)

    Abrupt and steep climate changes of the millennial scale as represented by the Dansgaard-Oeschger cycle (D-O cycle) and the behavior of the global surface layer system in their wake are outlined. The D-DO cycle is the abrupt and steep climate changes that are recorded in the Greenland continental ice sheet, and is grasped most typically as changes in the oxygen isotopic ratio in the ice. Studies reveal that the D-O cycle is a global episode that accompanied interaction between various subsystems constituting the global surface layer system. It is believed that in the D-O cycle there were changes not only in temperature but also in aridity/moisture and in the sea level, and probabilities are high that there was a great local variation in the way the changes took effect. The possibility has now become lower that the D-O cycle occurred in the interglacial epoch in the high latitude belt in the northern hemisphere, yet it remains likely that the climate changes driving the D-O cycle continued in the low latitude belt. 57 refs., 8 figs.

    Discussions were given on detergents, washing agents and a possibility of a washing technique that impose less loads on the environment. Compacted granular detergent is the mainstream in detergents for clothing. The detergent has a reduced volume, but contains more normal chain alkylbenzen sulfonate (LAS) as a surfactant than the conventional detergents. The current annual consumption of synthetic detergents reaches about one million tons, and soaps about 200,000 tons. Overpopulation and depopulation have become extreme depending on areas, whereas urban areas consume detergents five to ten times the national average. The number of corporations in the soap and detergent industries who take environmental effects of detergents seriously and are trying to develop environment friendly detergents is increasing in recent years. Most of these detergents use natural plants as their main material, using no synthetic surfactants or additives. Bearing the cost for environmental loads and considerations on environment preservation may be adequately incorporated if individuals and corporations make economically reasonable decisions. 7 refs., 32 figs., 18 tabs.

    For the purpose of the international standardization, conducted was a R and D of `the economic evaluation method of environmental impacts.` Survey/analysis were conducted of the trends in the U.S. and Europe where the study on environmental costs is advancing, and study systems were constructed in cooperation with Resources for the Future (RFF), the U.S. Electric Power Research Institute, the University of London, etc. As to impact analysis models, the development of environmental excrement transfer models has been finished, and the development of D-R relational equations which reflected characteristics in Japan has been started. In the joint study with the U.S. RFF, conducted were survey/analysis using the CVM (contingent valuation method). By the comparison of the survey data with actual medical data and comparison with the economic value conversion method, etc., validity and consistency of the CVM method were verified. As a result, it was found that these survey data could be explained without inconsistency. A case study of the environmental cost evaluation was made for electric power, iron/steel and electricity, and it was verified that this developmental method was fully applicable to the environmental impact evaluation of the actual production system. 27 refs., 33 figs., 89 tabs.

    A potential study in FY 1998 was made of the energy/environment related activity implementation joint (COP3 related AIJ) in 6 Southeast Asian countries. Vietnam is a country which is the lowest in greenhouse effect gas (GHG) emission in the world, but they want the international assistance for their continued development and contribution to the global environment. Laos has to continue their economic development for extermination of poverty and improvement of life level. Accordingly, AIJ has to be the one that supports those and is helpful for both industrial development and environmental improvement. The same in Cambodia as in Laos, AIJ has to be the one that is helpful for both industrial development and promotion of environmental improvement. In Myanmar, GHG emits (CO2 conversion) 94.5% in the agricultural sector where methane is emitted from livestock and rice growing. There, the forest protection plays a big role. In Thailand, the use of land and forest protection are subjects mainly with the heightening of energy efficiency and fuel substitution. Malaysia, of course, promotes the economic development, has the leading GHG policy (traffic management in urban area, etc.), and wants the international technology transfer. (NEDO)

    Discussions were given on the new energy vision at Ueki Township in Kumamoto Prefecture. The total energy demand in Ueki Township is 898 x 10{sup 7} Kcal. of which about 44% is accounted for by the transportation department, 34.7% by the industrial department, and 21% by the consumer department. The total available regional new energy amount is estimated to be 52.1 x 10{sup 6} kWh/year, which is consisted of stockbreeding wastes energy at 44.1%, solar energy power generation at 33.2% and solar heat utilization at 22.6%. Introduction of wind energy was judged impracticable. The new energy introduction plan calls for introduction of solar energy power generation for lighting and air conditioning of the diamond shaped nursery school, the Yamamoto nursery school, the Ueki Township office building, the multi-purpose sports center, the Ueki Hospital operated by the national health insurance, the multi-purpose health and welfare center, Yoshimatsu Sports Park, and Tahara Sports Park. A subsidy institution by the local government was discussed as the proliferation plan of solar energy power generation systems to be installed in individuals' houses and enterprises, with which introduction to residential houses of about 30% was targeted by 2010.

    Based on the basic quality equation of photovoltaic (PV) cell, a quality equation of PV module has been constructed by considering the spectral distribution of solar radiation and its intensity. A calculation method has been also proposed for determining the output from current-voltage (I-V) curves. Effectiveness of this method was examined by comparing calculated results and observed results. Amorphous Si (a-Si) and polycrystal Si PV modules were examined. By considering the environmental factors, differences of the annual output between the calculated and observed values were reduced from 2.50% to 0.95% for the a-Si PV module, and from 2.52% to 1.24% for the polycrystal Si PV module, which resulted in the reduction more than 50%. For the a-Si PV module, the environmental factor most greatly affecting the annual output was the spectral distribution of solar radiation, which was 3.86 times as large as the cell temperature, and 1.04 times as large as the intensity of solar radiation. For the polycrystal PV module, the environmental factor most greatly affecting the annual output was the cell temperature, which was 7.05 times as large as the spectral distribution of solar radiation, and 1.74 times as large as the intensity of solar radiation. 6 refs., 4 figs., 1 tab.

    For global scale measures to be taken for environmental protection, it becomes more and more important in the future to positively transfer and spread energy conservation technologies of Japan to overseas countries. Especially, it is effective for both economic growth in the Asian region and global environmental protection to transfer technologies which the oil refining industry has been developing and accumulating. Energy conservation in the oil refining industry means the energy conservation by strengthening the operational control at the first and second oil crises in the first stage, the energy conservation in the second stage which was accompanied by small and medium scale plant/equipment investments during several years after the first stage, and the energy conservation in the third stage which was accompanied by large scale investments from the first half of the 1980s to the present, resulting in improvement of 40% over before the first oil crisis. As to environmental protection measures, measures to reduce waste from oil refinery against air pollution and water pollution were prepared by the first half of the 1970s, and technologies were established of waste water treatment, flue gas desulfurization and denitrification. A lot of facilities for improvement of product quality and for low pollution were installed. In addition to environmental technologies, also in other industries, there were seen the heightening of thermal efficiency of kiln and thermal efficiency of cooling technique of clinker cooler in the cement industry and the improvement of productivity in the paper/pulp industry. 360 figs., 62 tabs.

    This paper takes up and explains recent topics on chemistry and technology. Phase of electron transition in molecules in aqueous solution alleviates very quickly, of which observation technology using femto-second photon echo is introduced in the paper. A description is given on chemical imaging of individual atoms and molecules on surfaces by using a scanning force microscope. Cytochrome C-oxidized enzymes get involved in respiration chain reaction to reduce oxygen molecules into water, whereas structural analyses would move forward studies on mechanisms for proton moving process associated with electron movement. Researches by Milstein et al resulted in success of selective severing of strong carbon-carbon bond by using an Rh-complex. The paper describes the following items: random glycosidation intended of structuring an oligosaccharide library, application of photochromic molecules to next generation photomemory materials, and temperature response and shape memory characteristics of polymer gels having a crystalline structure. The paper takes up in the field of molecular biology the salt resistance donation to plants by using gene engineering, and appearance and diffusion of C{sub 4} plants as seen from carbon isotope ratio. 39 refs.

    The coal utilization is expected to make substantial growth according to the long-term energy supply/demand plan. To further expand the future coal utilization, however, it is indispensable to reduce environmental loads in its total use with other energies, based on the coal use. In this survey, a regional model survey was conducted as environmental load reduction measures using highly cleaned coal which were taken in fiscal 1993 and 1994. Concretely, a model system was assumed which combined facilities for mixed combustion with coal and other energy (hull, bagasse, waste, etc.) and facilities for effective use of burned ash, and potential reduction in environmental loads of the model system was studied. The technology of mixed combustion between coal and other energy is still in a developmental stage with no novelties in the country. Therefore, the mixed combustion technology between coal and other energy is an important field which is very useful for the future energy supply/demand and environmental issues. 34 refs., 27 figs., 48 tabs.

    Out of the development of technology to arrange the aquatic environment using phenomena of microorganism fixation on carbon fiber soft textures, the paper stated the fiscal 1997 result. On carbon fibers in a state of swaying in water, microorganisms in water fix in an amazingly large quantity. A catalog was compiled of 58 kinds of carbon fabrics trially woven and knitted. When carbon fiber is used as activated sludge carrier, activity of microorganism lasts more than one year. Only a little amount of surplus sludge is generated. The fixed microorganisms are more active in case of carbon fiber than in case of nylon and polyester fibers. Fiber texture models of carbon fiber fixing activated sludge groups were proposed. By pump operation, the water flow inside/outside microorganism groups is being accelerated. Several new strains of bacillus carboniphilus were isolated/identified from soil and marsh. To grasp relationships of characteristics among three elements such as the state of aquatic environment, fiber, and microorganism group, the experiment was prepared. Preliminary work is conducted to derive a simple equation for facility design, and experimental directions to obtain design conditions were proposed. 6 refs., 166 figs., 47 tabs.

    This project is aimed at internationally cooperating in the R and D of industrial technology and improving industrial technology of Japan. For it, the following three technologies were investigated: 1) environmental preservation technology using biotechnology, 2) technology for effective use of unused hydrocarbon resource, 3) solid electrolyte fuel cell (SOFC) technology for high-efficient electric vehicles. In 1), bio-remediation is a choice as the result of trially using technologies for remediation of the environment polluted by pollutant, but it is not a technically completed one, but one which will be improved by trial and error. By the application of gene engineering, the use of gene recombination enables wide spread of decomposition genes. In 2), technical subjects were studied such as superheavy distillate, oil shale, coalhead methane and methane hydrate. In 3), designed were cylinder type and planar type SOFC of 850degC operation and 10kW output. Accumulation and weight of a total SOFC system are 81 liters and 100 kg in cylinder type and 136 liters and 200 kg in planar type. The vehicle can be equipped with the SOFC. 171 refs., 72 figs., 54 tabs.

    In order to investigate useful protective medicines for the relief of skin injury induced by irradiation, 60 methanol extracts of Chinese traditional medicines were used in the test of protective potency on skin injury. ICR male mice at 6 weeks of age were whole-body irradiated with 1100R by using a soft X-ray generator (30 kVp, 10 mA, 190 R/min). Each methanol extract of these medicines was injected intraperitoneally into mice before or after irradiation. The degrees of skin injury were determined by a score system of skin reaction within the observation period from 21st to 40th day after irradiation. Protective potency of each medicine on skin injury was calculated from the maximum mean scores of administrated group and un-administrated group. As a result of these studies, the protective potency was detected in Unsei-in, Kumibinro-to, Keisi-syakuyaku-chimo-to, Keigai-rengyo-to, Gosyuyu-to, Koso-san, Saiko-seikan-to, Syo-kankyo-to, Syo-saiko-to, Syoma-kakkon-to, Sen-kan-meimoku-to, Zokumei-to, Sokei-kakketu-to, Bokuryo-in, Mao-to and Rikkunsi-to by intraperitoneal injection before irradiation. Of these effective medicines, only Unsei-in and Mao-to are shown to have a significant protective effect by intraperitoneal injection after irradiation. (author).
