    This paper introduces the American International Group (AIG) which makes conceptions and risks of bio-remediation its business, as to how the Group is really working on the business. Features of the continuing remediation involving corporations managed by AIG include the following: It has economical superiority; in-situ purification of contaminated soils is possible; and it can solve contamination issues in a short time, and makes reuse of lands possible. The remediation uses a principle of promoting the contamination purifying actions of the natural world. It activates microorganisms by supplying oxygen, water, and nutrients in suitable amounts for microbial activities to decompose chemical wastes and converts them into harmless substances such as CO2. Objects of purification include petroleum-based substances, herbicides, insecticides, and solvents. Establishing optimal parameters before purification (mediator variables and population parameters) and protocols is important. The system goes through the following steps: Hydraulic and geological experts identify patterns and levels of contamination; microorganism experts find optimal parameters in laboratories; engineers design treatment systems; and site technicians operate the system. 6 refs., 3 figs.

    Elaboration of the action plan for the New Earth 21 plan proposed by Japan in Houston Summit was researched. In fiscal 1995 three types of energy supply/demand scenarios, sensitivity analysis under various conditions, and cases presupposing CO2 emission regulations or not were evaluated by analysis toward 2050 using the New Earth 21 Model (NE 21 Model). Energy-saving is important, and CO2 recovery/treatment technology is introduced according to CO2 emission regulations, while attention is focussed on biomass energy. The issue of solar and wind power generation is cost reduction. In a presupposed horizontally integrated energy system, methanol represents an important intermediate energy. As a whole, CO2 reduction can be achieved by various combinations of energy-saving, introduction of regenerative energy, and CO2 recovery/treatment technology. Case studies of the action plan were conducted by unifying the evaluation criterion on coal IGCC, photovoltaic generation and biomass. The NE 21 Model was useful for elaboration of the reduction scenarios of CO2 emission. 26 refs., 84 figs., 28 tabs.

    It is necessary to establish scenarios for reducing CO2 emissions and for developing CO2 emission control technologies to obtain a global consensus, using appropriate analytical models. For modification of the DNE-21 (Dynamic New Earth 21) model, it has a category designated as innovative technologies not involving CO2 emission and an optional consideration for the absorption of atmospheric CO2 by biomass. A global carbon circulation model, including vegetation in its scope, is also incorporated. Major results of the simulation are shown. When 20% reduction in CO2 emissions is required for only OECD countries after the year 2020, it has been demonstrated that CO2 concentration in the atmosphere will reach as high as about 900 ppm in 2100 due to CO2 emission by developing countries, and will not be a tolerable level. Under the condition that CO2 concentration in the atmosphere is controlled at 450 ppm in 2100, the amount of renewable source of energy from photovoltaic power generation and biomass will increase and technologies of CO2 recovery and storage will decrease. Research and development of the production of methanol from recovered CO2 will be adopted as innovative technology for CO2 measures. 69 refs., 112 figs., 79 tabs.

    For sufficient transportation capacity and passengers comfort and convenience, it is very important to design the suitable lift systems (e.g., the appropriate number of cages, velocity, capacity etc.) using a model which describes real elevator movements. The procedure used in conventional design calculations for office buildings is to determine the transportation capacity for the up-peak traffic situation using a simple passengers arrival model. This paper presents a new design calculations using balanced traffic model, which can deal with the elevator movements considering passengers arrival rate. As some performance indexes to evaluate the quality of service can be calculated by using this model, lift system designers can determine the appropriate lift facilities as to satisfy their goals. The validity of the proposed model is also shown by comparing with the measured data in real lift systems. 6 refs., 9 figs., 2 tabs.

    The average temperature in the summer season at Wakkanai is 19 degrees C, and below zero degrees C in the winter season. Solar radiation duration is shorter in November through February due partly to the presence of snow. In terms of total solar radiation amount, the city occupies a middling position in the whole Hokkaido island. As for the force of the wind, a daily maximum wind velocity of 10m/s or stronger occur on 8 to 10 days every month in the period October through May. As projects for promoting new energy introduction, the below-named ones are chosen and subjected to examination for feasibility. They are a wind power generation system for a water purification plant; a district heating system utilizing cogeneration at the city middle sector; a hybrid system of methane fermentation and wind power generation for a public stock-rearing farm; a hybrid system of cogeneration and photovoltaic power generation for Fujimi district accommodation facilities; and photovoltaic power generation as a clean energy introduction system for a general gymnastic hall of Wakkanai City. Since the above-named subjects are all excellent in economy and environmentally-friendliness, it is suggested that efforts be exerted to realize them. (NEDO)

    The outline of the Tatara Bridge is given to introduce the features of the entire structural system and fundamental problems concerning the construction of the huge cable stayed bridge. The central span of the bridge is 890m. The topography and geological features of the bridging point are reviewed, and social conditions such as being in a national park, safety for sailing, etc. are taken into consideration for various technological studies on the construction of the huge bridge. Bridge piers are provided in the side spans and appropriate counter weight is loaded to design a more economical bridge which is more suitable for the topography as compared with a suspension bridge. The cable stayed bridge requires no anchorage which is necessary for a suspension bridge with very little topological alteration, and an excellent result is obtained both in cost and term of construction as compared with a suspension bridge. The rigidity of the cable stayed bridge is high, and the stability of the resistance to wind of the structure is also very satisfactory. As a result, it is concluded that the bridge can be designed and constructed using currently available technologies, and a cable stayed bridge is selected in August, 1990 as the type for the Tatara Bridge. 9 figs., 1 tab.

    This paper describes the planning and design of the Ikeda-Lake Bridge of the Tokushima Express Way. This bridge is a PC (prestressed concrete) five-span continuous balanced arch bridge with a length 705 m. This bridge transverses prefectural road, Ikeda Dam Lake of Yoshino River, park, JR line, national highway, and town road, and both ends of the bridge are tunnels, resulting in the complicated bridging condition. Various bridging methods were examined from the viewpoint of structural characteristics, workability, profitability, maintenance/management, and aspect. A bridge with PC stiffening girders was adopted. The maximum interval between supports is 200 m. This bridge has the largest scale as a concrete arch bridge in Japan. Basements of bridge piers were constructed by pneumatic caisson method and large-diameter deep basement method. Since basements were located in the dam lake and they were quickly constructed in a short period in a non-flood season, steel caissons were separately fabricated in the dock, towed and placed for excavation. For the construction of upper section, overhang method was adopted using movable working vehicle. For the construction of arch section, the arch was overhung simultaneously in the both sides by composing the truss using stiffened girders, arch ribs, vertical members, and temporary cable stayed members, which was the first in Japan. In 1997, basement construction was completed, and construction of bridge piers and a part of the construction of upper section have been started. 2 refs., 12 figs.

    As the research study contributing to implementation of 'The New Earth 21' proposed by Japan at the Houston Summit in 1990, a DNE21 model was developed as a quantitative assessment model for global warming preventive technology, heightening of efficiency of the global energy supply/demand system, conversion to energy sources of low carbon emissions, etc. In the project of 'The New Earth 21,' economy and environment can be compatible centering on developed countries' technical development and technology transfer to developing countries. In FY 2000, for heightening applicability of the DNE21 model, the world, which was used to be divided into 10 regions, was divided into 54. At the same time, a prototype model was constructed in which cities in the region were divided into three cities: large; medium; small. Using the DNE21 model, evaluation was made of effects of uncertainties such as population, economic growth, final energy demand and cost as preconditions of the model on the optimization of global warming preventive measures. Further, technologies which are expected to be important for global environmental policy in the ultra-long term were listed up to estimate the potentiality. (NEDO)

    Japan proposed in the Houston Summit the New Earth 21 to be carried out with technology development and technology transfer, and to make a concrete development of the project, Japan also proposed in the Tokyo Summit a TREE Plan for working out comprehensive strategies of the innovative technology development. In the CO3 Kyoto Conference in 1997, numerical targets for developed countries were determined which have legal binding force for control/reduction of greenhouse gas emissions in the term of 2008-2012. It was agreed to urge developing countries also to play a certain part in the project through the clean development. Therefore, the paper made quantitative analysis of important CO2 prevention technologies, technology transfer costs, and economical assessment by energy conservation. As a model, the DNE 21 model was upgraded and used into which CO2 prevention technologies, energy, economy and climate changes were integrated. In fiscal 1997, the following were carried out: collection of data on important CO2 prevention technologies and systems and analytical assessment using the DNE 21 model, CO2 reduction and selection of energy technology, assessment of energy system costs, construction of the unified DNE 21 model, and opening of the international workshop. 62 refs., 98 figs., 34 tabs.

    For the establishment of a CO2 measures introduction scenario which the world would accept, the latest information was collected, the DNE21 (Dynamic New Earth 21) model was improved, and simulation was reviewed. In fiscal 1998, simulation was performed for each district using an LDNE21 (Linear Dynamic New Earth 21) model, and an energy flow chart, energy balance table, and trade table were prepared and subjected to detailed deliberation. Studied were also conducted about the changes to occur in methanol production when the natural gas reserves and plant cost data were given different values. In the DNE21 model, the 'macro economy model' and 'warming damage function' were integrated, and simulation was performed for verification. Using a standard model compatible with COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change), comparison was made between a case in which different CO2 emission constraints were imposed on the advanced area and developing area separately and a case in which one and the same constraint was imposed on the world as a whole, and calculations were made about CDM (Clean Development Mechanism).

    This paper reports fiscal 1999 survey of the new earth program. Toward the target of GHG (green house effect gasses) 550 ppm, sensitivity analysis using a linear DNE21 model was replenished, with model analyses made on a scenario concerning the countermeasure technologies/systems. In other words, performed were the improvement of accuracy by the renewal of data, sensitivity analysis concerning CO2 collection/processing technology and nuclear energy, analysis of the international regulation for controlling CO2 concentration under 550 ppm in the air in the year 2100, and sensitivity analysis on increase in per capita energy demand in Asia. Overall assessment of global warming problems was upgraded for the purpose of enabling the assessment from the consumption maximization point of view, taking into consideration cooling effects of SOx and economic growth. Potentiality assessment in rational use of energy was reexamined because energy conservation played an important role. That is, in DNE model, the data were examined of OECD signatories and developing countries from 1970s concerning natural gas, petroleum, coal and electric power, with the long-term cost flexible value estimated. In addition, feasibility was assessed of rational use of energy from energy GNP unit. (NEDO)

    The present report explained how to plan the drilling of geothermal well, and select the easing, drilling mud water and drilling rig in order to obtain the steam and hot water. The geothermal wells can be generally classified into exploration wells, production wells and reduction wells. The exploration well is a well to survey the underground strata, geological structure, and existence of steam and hot water, while the production well is a well to produce the steam and hot water. The reduction well is a well to condense the hot water produced by the production well and steam having passed through the power-generating turbine, and return them as condensate underground. The geothermal well is characterized by its high temperature, mud leakage, corrosive matter and scale, all of which make its drilling difficult and its management troublesome for the production and reduction. To plan the drilling, the order of processing are distinct conditioning of drilling differently by type of well, collection of geological survey data, programing for the casing and selection of drilling rig. The present report also gave the stress to affect the casing and standard of steel pipes to be used for the casing. 3 figs., 4 tabs.

    In the United States, high speed transportation plan was approved in 1965, and research and development of the superconductive magnetically levitated system (Maglev) became active. Although research and development for design, construction, and test for 500km/h Maglev were started in 1974, the federal government ordered to stop in 1975 all the development projects of high speed transportation traffic systems, and the activity slowed down very much as compared with those in Japan, Germany, and other countries. In 1990, the National Maglev Initiative (NMI) project was established. The feature which is different from those of Japanese and German systems is 0.16g and larger acceleration, which allows to shorten the transit time between stations. Development plan for Maglev prototype was approved officially in November, 1991. Features of levitation, guidance, propulsion as well as the carriage lineup of the 4 systems conceptually designed in the NMI project are introduced. 22 refs., 4 figs., 57 tabs.

    To supply cheap, high-reliable and a planty of the electricity is an important task of the electric supply system because the requirement for the electricity is rapidly increased in Japan. In order to solve this problem, the authors of the paper are developing a most suitable practical method based on algorithm, according to which the generation expansion planning is divided into two problems: the optimal generation mix and the optimal generation construction process and the two problems are solved respectively. But there are some bad points in the method, for example, there are only approximative practical restriction of the capacity of single machine and the existing electric supply etc., because the optimal generation mix is determined on the basis of non-linear planning. So, in the present paper, the electric supply support system is practically constructed while proposing an unified generation expansion planning based on the dynamic programming that is possible to consider these restrictions strictly and the usefullness of the method is inspected. 12 refs., 7 figs., 5 tabs.

    This research program consists of (1) the solid catalyst-aided reforming of various petroleum based oils and heavy coal oils into Solvolysis solvents and the secondary hydrogenolysis, (2) a search for pre-treatment for improvement on the sub-bituminous coal liquefaction yield, and (3) a search for measures for improvement on the brown coal liquefaction yield. Studied in this fiscal year are (1) the high-temperature short-contact time liquefaction of brown coal, (2) the role of catalyst support for selective upgrading of SRC (solvent refined coal), and (3) reforming of thermal melting feature of low rank coal by preliminary deashing at room temperature. In relation with Item (1), it is found that the dehydrogenation or reaction to carbonization of molecules involved in hydrogen donation is structure-sensitive but that thermolysis of coal is accelerated under high-temperature conditions to allow transfer hydrogen to contribute uniformly. It is deemed also that matching is excellent between hydrogen transfer and thermolysis, that the solvent dissolution level is elevated, and that the reaction short in duration inhibits consecutive polymerization reaction. These are supposed to be effective in improving on the liquefaction yield and in rendering heavy constituents lighter. In relation with Item (2), it is found that the experimentally manufactured catalysts are effective in reducing the weight of heavy constituents. In relation with Item (3), a carbonization reforming method is experimentally implemented in which the ash that affects carbonization is further removed by a pre-treatment at room temperature.

    This report presents the results of (researches on solvolysis liquefaction mechanisms and reaction promotion with oil- and coal-based solvents), conducted as part of the research and development project for coal liquefaction techniques. The FY 1981 program includes researches on (1) the effects of liquefaction reaction conditions on liquefaction yield and production of light products for coal species of low degree of carbonization, including brown coal, (2) the effects of pretreatment of coal on its liquefaction reactivity, and (3) up-grading of the solvolysis coal liquid (SCL). For the item (1), HA240 (hydrogenated Ashland's A240) is used to investigate its liquefaction capacity for various coal species of low degree of carbonization, including brown coal. For the item (2), the effects of pretreatment in a hot water bath with reflux was investigated for sub-bituminous coal in the FY 1980. In the FY 1981, various pretreatment methods are attempted for enhancing liquefaction reactivity of brown coal. As a result, it is found that ash content of brown coal is decreased to one-third of the initial level, when it is treated in a diluted hydrochloric acid bath with reflux. For the item (3), SCL hydrogenated by Birch reduction (B-SCL, 1) is compared with H-SCL with respect to properties, structures and thermal crackability, to discuss the items required for the catalyst to be used in the second stage by clarifying effectiveness of the catalyst.

    The NEDO's representatives visited Europe and China with the objectives of, e.g., international cooperation and information exchanges for medical treatment/welfare equipment. For the welfare equipment technologies, they visited the research institutes and facilities in UK and Germany, among others, to find that the European countries place more emphasis on researches to meet the needs than on advancing the equipment itself. For the medical treatment equipment, they visited the bio-research institutes in Europe for exchanging information on post-genome and tissue engineering. The European countries are behind USA in research fund and manpower for bio-technology and bio-medical, although making great efforts with much expectation on these areas. The China's medical treatment/welfare technologies seem to be clearly still in the stage of needing aids rather than rendering cooperation. However, China has been producing a number of new products in the areas where her traditional arts of medicine are combined with advanced techniques of the West, e.g., those for examination, as felt from a number of the equipment types presented to the China Medical Treatment Equipment Exhibition.

    The aim is to develop a method of processing oxygen concentration distribution in human organs into an image by computed tomography using near infrared rays capable of transmitting through living tissues. Since the photoabsorption spectra of hemoglobin etc. in blood vary according to the degree of their oxidation, an oxygen concentration level is determined by measuring the magnitude of the variation. In the imaging method named in the title, the object is irradiated with picosecond-level near infrared pulses from all directions successively, the pulses after transmission through the object are measured at all directions at a picosecond-level time resolution, and the distribution of pulse scattering and absorption characteristics are subjected to algorithmic calculation, the outcome is converted into oxygen concentration levels, and an image is obtained. A 64-channel time resolution measurement system is constructed, and is applied to living tissue models (phantoms) and animals, and an image is obtained and evaluated. On the basis of the result, a patient is examined for clinical evaluation, and an image reflecting the distribution of variations in hemoglobin oxygen concentration is obtained for the head of the adult patient. A spatial resolution of 1cm is achieved in case of a phantom 10cm in diameter. In the case of 64 channels, measurement takes approximately 20 minutes and mapping image data measurement takes approximately 7 minutes. (NEDO)

    Research and development of a lavatory training system is carried out to enable bed-ridden aged people to evacuate unaided and thereby to elevate their consciousness of self-reliance. The developed system consists of a multi-functional bed with a built-in transfer unit and a movement assisting system. The multi-functional bed consists of a device that automatically transfers the patient abed to a position on the bedside portable toilet, a device that is remotely controlled to change the posture of the patient from the in-bed state to a seated state, and an audio-visual system that encourages the patient into self-reliance. The movement assisting system enables a patient, who needs people's help in rising from the bed and in walking to the lavatory, to stand up, sit down, and walk, all unaided. The system has undergone field tests at 6 locations in hospitals, public facilities, and residential houses. The result is that for people of Category III it is almost certain that they can travel safely thanks to the system. The system is again evaluated high in barrier-free residential environments.

    For the purpose of grasping the present situation of the development/production/spread of welfare apparatus in north Europe, an investigation was conducted paying visits to Sweden and Denmark. Basically in the Swedish policy for handicapped persons, disablement is defined not only as features which belong to each individual, but as problems arising when the environment surrounding each individual touches one another. Moreover, characteristics of their policies on welfare apparatus are that major welfare apparatus can be provided for the disabled free of charge, and that the government and public organs play a major role in each step of the development, evaluation, distribution and provision of welfare apparatus. Features of the market of welfare apparatus are that users and buyers of the apparatus are different persons, that a public corporation called SUB participates in determining selling prices, etc., and that the market reflects needs and requests from users comparatively naturally. The needs for welfare apparatus at the Research Institute of Handicapped Persons are grasped through opinion exchanges with groups of handicapped persons or information exchanges with the technical aid center. 3 refs., 11 figs., 10 tabs.

    A study is conducted of a plan to repower the Ashuganji thermal power station, the People's Republic of Bangladesh, with the plan to be connected to the clean development mechanism (CDM). For conversion of the existing No. 3, No. 4, and No. 5 generators (each outputting 150MW) into full fired heat recovery combined cycle generators, 31MW gas turbines are added, one to each of the three. The construction cost is calculated to be 14,000-million yen. Fuel (natural gas) will be saved by 28kt/year/generator, the three saving 2.1-million tons in total in 25 years. There will be a CO2 reduction of 77kt/year/generator, the total reduction to be 5.8-million tons in 25 years for the three generators. Then payback is assessed. In the main case (with the repowering-created increase in output to be used to cover the current power supply shortage), where the internal rate of return of 8.09% is much lower than the discount rate of 15.5% during the 10-year period for payback in case of financing by private funds, the discounted present worth is predicted to be negative and then the project is not feasible. Since there will be no problems about the repayment of borrowed money, however, it is hoped that low-interest special yen credit will be granted for the elimination of chronic power shortage. When it comes to international emission trading (550 yen/ton of CO2), payback is again found to be impossible. (NEDO)

    Theory of parameter setting for data acquisition is arranged, mainly as to the seismic generating and receiving geometry. This paper also introduces an example of survey planning for three-dimensional land seismic exploration in progress. For the design of data acquisition, fundamental parameters are firstly determined on the basis of the characteristics of reflection records at a given district, and then, the layout of survey is determined. In this study, information through modeling based on the existing interpretation of geologic structures is also utilized, to reflect them for survey specifications. Land three-dimensional seismic survey was designed. Ground surface of the surveyed area consists of rice fields and hilly regions. The target was a nose-shaped structure in the depth about 2,500 m underground. A survey area of 4km{times}5km was set. Records in the shallow layers could not obtained when near offset was not ensured. Quality control of this distribution was important for grasping the shallow structure required. In this survey, the seismic generating point could be ensured more certainly than initially expected, which resulted in the sufficient security of near offset. 2 refs., 2 figs.

    For active safety enhancement, drivers will be provided with information and warning that will help them drive with safety. Studies are under way about functions to facilitate drivers' perception and to lighten the burdens imposed on them. As for accident avoidance techniques, onboard systems will perform controls involving vehicle maneuver for safety enhancement. This includes the improvement of vehicle maneuvering performance, in addition to brake control and steering control, for lightening drivers' burdens and for complementing their operating skill. Danger avoidance is based on the concept that the related system is to work in case warnings alone are not enough to avoid a collision. Full automation will be implemented by two ways, the autonomous way aided by the existing infrastructures such as GPS (Global Positioning System) or the way in which infrastructures to be newly built will be utilized. Passive safety technologies aim at minimizing damage upon collision, and involve structural improvement, air bags, etc. Disaster aggravation prevention means to prevent disaster from spreading after collision. Communication is one of safety-related elements on which studies will continue. Under the Phase 2 ASV program, research and development will be conducted for putting passenger cars to practical use, and the same will be conducted, in the case of large vehicles and motorcycles, for the construction of their prototypes.

    This paper summarizes the achievement report on the Sunshine Project in fiscal 1979 for hydrogen energy research. In hydrogen manufacturing technologies, the paper describes improvement in membrane performance and discussions on electrode materials in high temperature and pressure electrolysis. In the thermo-chemical method, hydrolysis of iron bromide (II) in the iron system cycle was compared to three kinds of reaction patterns corresponding to phase change, and evaluation was given as the hydrogen generating reaction. In the iodine system the first stage oxidation and reduction reaction of MgO-I{sub 2} was subjected to a continued experiment by using a batch autoclave. Discussions were continued on device materials for the iodine cycle. In the light irradiation electrolytic method for the mixed cycle, the light intensity was experimented at a force 12 times greater than that of the solar beam, and a reaction rate of 80% was achieved. Raising the temperature causes the reaction rate to decline, but it can be supplemented by raising the light intensity. A heat diffusion column was found effective in HI decomposition (hydrogen acquisition). For hydrogen transportation and storage, researches are continued on metal hydrides. In hydrogen utilization technologies, combustion, fuel cells (using high temperature solid and alkaline aqueous solution electrolytes), and hydrogen engines are studied. This paper also describes studies on hydrogen safety assuring measures and energy systems. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1988 in studies on coal liquefaction. The liquefaction mechanisms may be conceived to work in the following three manners: radicals produced by spontaneous bond and cleavage of coal molecules draw out hydrogen from the donor and stabilize it; bond, cleavage and stabilization due to hydrogenation from the donor to coal aromatic nucleus; and cleavage and stabilization due to work of active hydrogen discharged from the donor. How these mechanisms contribute to composition of the products depends on coals, liquefying conditions, and reactivity of the donor. Selection of the donor solvent requires design by which high liquefaction yield can be obtained with small amount of solvent. The oil plus asphaltene yield could have been approached to the ideal value through the moving liquefaction of gaseous phase hydrogen and catalyst-free hydrogen, with the 4HFL to coal ratio at 1.5 to 1. The gaseous phase hydrogen was found effective in reducing 4HFL. Liquefaction residual oil manufactured from Morwell brown coal subjected to BCL was hydrogenated in single stage or two stages to compare and discuss the solvent sorting constituents, reactivity of CLVR, and how the catalytic activity deteriorates. The cause for the catalyst deterioration was elucidated, and considerations were given on catalysts and reaction conditions for lightening and refining of CLVR. (NEDO)

    The geographical position or environment is set on the assumption that the natural energy of a detached house is used in a hybrid state. Moreover, the energy consumption of the house and the natural energy supply obtained from the geographical position were compared and investigated. As a result, the energy consumption is 10,617 kWh, and the energy supply is 8,236 kWh. About 78% of the whole consumption can be theoretically made from natural energy. The energy supply is calculated on the low side during prediction. Therefore, an increase in the energy supply is expected by installing a solar collector based on solar energy, expanding the solar panel area, and increasing the number of wind mills. However, this energy is partially lost via an inverter while it is supplied to the general domestic equipment. At the six main points in Tokyo and its districts, the adaptability of natural energy used based on the regional characteristics is investigated presently and the installation of a system is examined. 13 refs., 2 figs., 6 tabs.

    This paper explains the involvement of the global environment action plan of Japan Society of Civil Engineers, Agenda 21, with civil engineerings and global environmental problems, as well as the global environment action plan. Global environmental problems require handling the matters in three ways: identification and elucidation of events, effect analysis estimation, and alleviation, avoidance and prevention of the effect. Settlement and proliferation of civil engineering technologies transferred to developing countries demand indispensably understanding such features of the developing countries as social and economic conditions, natural conditions, climates, histories, races, and cultures. Realizing the sustainable development requires the followings: formation of civil engineerings that contribute to improving global environments; development of civil engineerings that make coexistence of human being and other living organisms possible; analyses of effects and mechanisms of global warming and weather change and the corresponding technique and system development; and development of techniques to build resource circulating type national land and cities. It is also essential to move forward positively structuring civil engineerings that contribute to solving such global environmental problems as acid rains and marine pollution, and technical development thereof; providing guidelines on execution of international civil engineering constructions, and technical development thereof; developing civil engineerings in developing countries and assisting training of people.

    Feasibility of cabled-stayed bridges with 1000m-grade spans is discussed while re-examining the plan for constructing a Great Tatara Bridge to connect Honshu and Shikoku, Japan, and in this process various tasks and questions are isolated. Some which will be problems in designing the new bridge structure are taken up, including the load-bearing capability of the bridge as a whole, vibration of long cables, resistance to long-period earthquakes, and accuracy management during the construction work. Findings are stated below. A cable-stayed bridge is not significantly different from a suspension bridge and is sufficiently feasible until the span exceeds 1500m. When the span is longer, however, the bridge beam cross section needs be designed very prudently in view of the great axial force and wind load to be imposed on it. Effective for the assurance of load-bearing capability for a long-span cabled-stayed bridge is a structure in which load is elastically confined in the direction of the bridge axis. In connection with vibration damping for very long cables, it is verified that a new dimpled cable suits the purpose of suppressing wind load from increasing without reduction in damping effect. 28 refs., 23 figs., 7 tabs.

    The evacuation-support system is under development for not only the aged bedridden persons but also the persons disabled in exercising movement to excrete by themselves. When the person lying on his bed is going to excrete, his sequence of actions to be taken is to sit down on his bed, walk to the toilet, sit on it, simultaneously take off his clothes and excrete. After the excretion, the above actions are reversely taken as for as he lies on his bed. Researches are being made into the mechanical system which partially or entirely supports the above five necessary actions. The system structuring can depend upon the following five types of disabled persons` residual function: difficulty in sitting or moving without help. Paralyzed lower extremities and partially impaired upper extremities. Ability to walk with functional assistance. Ability to stand up with support but walk unstably. Ability to walk, leaning on and along the railing. In the present project, its three constituent elements are being developed which are the multi-functional bed internally equipped with transferring/riding/mounting apparatus, transfer support apparatus and multi-function portable toilet. The development of the present system is expected to be followed by that of the self-supporting excretion system which will be proper for Japanese houses. 3 figs., 1 tab.

    The systems in American and European countries for technological development of welfare-related equipment and tools are surveyed and analyzed, with the objectives to draw proposals for establishing the systems which help smooth spread of the research/development results. It is necessary, in selecting the research themes, to well balance the supports for research and development based on the ideas and initiatives by the researchers with those for the publicly invited themes in which the government narrows down the politically important items. For exchanging researchers, the program should help exchange researchers routinely, to match the needs and seeds. It is necessary for the research and development programs promoted by the government for welfare-related equipment to quantitatively grasp the characteristics of various body functions and deterioration of these functions by aging, and to encourage the new participants by providing them with the databases. For promotion of spreading the R and D results, it is necessary to develop laws and regulations which help reduce expenses of the individual disabled and aged, and promote purchase of equipment through insurance, like ADA and rehabilitation-related laws adopted by USA.

    Under study is the modification of the four antiquated 300MW brown coal-fired power plants of the Ryanzanskaya thermal power station. Under the modification program, the plants will be burning a mixture of 60% coal and 40% natural gas for an increase in efficiency and for a great decrease in greenhouse gas emission. The amount of greenhouse gas emission of 6,858,592 tons/year before the modification will be reduced by 19.4% to 5,532,198 ton/year. The budget for the modification will call for 719,731,700 US dollars. EIRR (economical internal rate of return) is calculated based on the figures provided by the Russian office concerned about the current fuel cost and the current rates for the supply of electricity and heat. It is found that EIRR fluctuates depending on the ruble/dollar exchange rate. Although it does not pay at the current exchange rate, yet, when a US dollar is worth 13.0 rubles, an EIRR of 15% will realize at an availability factor of 70%. The same result is obtained when the availability factor is 80% and a US dollar is worth 14.8 rubles. There is a plan to fire the plants with 100% natural gas in the future. If the plan is implemented, a modification to incorporate gas turbine combined cycle will become feasible. (NEDO)

    With an objective of saving energies and reducing greenhouse gas emission, discussions were given on a modernization plan for the Chhatak cement factory in The People's Republic of Bangladesh. The Chhatak cement factory having a nominal production capability of 267,000 tons a year uses mainly wet-type long kilns of old type, consuming a great amount of natural gas. The present plan has discussed adoption of the Japanese energy saving technologies. The technologies use a vertical roller mill for raw material pulverization, a suspension preheater and a short kiln for clinker sintering, a grate cooler for clinker cooling, and the pre-crushing system. The result of the discussions provided the prospects of reduction in the natural gas consumption at 50%, and reduction of electric power consumption at 16%. This will mean the annual reduction of about 22,000 tons as converted to crude oil. The CO2 reduction amount would reach 51,800 tons a year. The total investment amount would be US$37,327,000. The result of the financial analysis according to the case studies appears severe, wherein reduction of the various expenses is desired possibly by the finance from Japan with generous conditions.(NEDO)

    The basic experimental researches were carried out for coal liquefaction by solvolysis. The studied items include hydrogenation conditions for treating the primary liquefied products, asphalt, pitch and model solvents (e.g., anthracene oil) in the presence of a commercial catalyst, solvolysis conditions for finely divided, molten coal using a hydrogenation recycled solvent, hydrotreating solvents, analysis of solvolysis-liquefied products, and liquefaction capacity of fractionated solvents for finely divided, molten coal. The studied items for separation of minerals include settlement at high temperature of the solid residue from the first liquefaction stage, and changed coal particle size distribution as a result of the first-stage liquefaction reactions in the presence of a hydrogenation solvent. The experimental study results indicate that conversion of finely divided molten coal into asphaltenes and preasphaltenes is notably accelerated in the phase-II coal liquefaction process by solvolysis, when a hydrotreating solvent is used for the first stage solvolysis process.

    On the basis of Kyoto Protocol-provided flexible measures such as joint implementation and clean development mechanisms, a study is conducted for introducing combined cycle into Konakovo Power Plant of Russia currently equipped with antiquated eight 300MW power plants constructed in the 1960's for which early renovation is necessary. The power station is an important power source connecting to the Moscow-Petersburg main. The gas turbine combined facilities to be newly installed will comprise 250MW-class state-of-the-art gas turbines arranged in four blocks, capable of a total output of 1600MW at a thermal efficiency of 58% (with simultaneous supply of heat). Four units capable of 1200MW out of the existing units will stay in operation for load adjusting. Since the price of power is set low under government control, the accounting capital/internal return rate is as low as 2.3%. The rate recalculated under the financing conditions of special yen credit for environmental protection, however, is as high as 19%, so high as to make the renovation an economically feasible project. It is expected that there will be an annual CO2 reduction of 2.3-million tons or a reduction of 57.50-million tons in 25 years (the life span of the new facilities). The renovation may be a joint implementation project to which both Japan and Russia will attach the highest priority. (NEDO)

    R and D was conducted for the purpose of developing the alternative natural gas manufacturing process that, using coal as the raw material, is highly efficient as well as environmentally superior, with the fiscal 1996 results reported. A test research was carried out on the coal hydrogasification process which was selected as the optimum process based on the studies in the previous years. On the basis of the results of the studies, a free fall pyrolyzer was employed as the test equipment for the use of behavior research of hetero-elements in the test. The basic specifications were set based on a hydrogen/coal ratio of 0.2, a temperature of 950 degrees C and a pressure of 7 MPa, which are the reaction conditions of the ARCH reactor, with the basic design drafted accordingly. In a preliminary examination on the mechanisms of the coal hydrogasification reaction, analysis was made on the representative 20 different kinds of coals, on the six kinds of which studies were made on the gasification behavior using a constant heating rate pyrolyzer. As a result, from the temperature dependency of a methane forming speed, it was assumed that three components of coal had bearing upon the gasification behavior. (NEDO)

    Researches are conducted for the development of a technology of producing useful gases such as acetylene, hydrogen, carbon monoxide, etc., from coal by the use of the high temperature and high-density energy of the plasma jet. In an experiment using a 100kW 3-port plasma-aided gasification unit, rapid quenching tests are conducted using hydrogen and helium, where the reaction furnace is changed, the specimen feed device is changed, and the plasma torch head is replaced by a high-power head. In a test of the coal specimen, it is found that rapid quenching exerts a great effect on the prevention of re-decomposition of the generated acetylene into hydrogen and carbon black and that a rise in the hydrogen partial pressure results in a great decrease in the quantity of acetylene generated. The said torch head replacement increases the rate of the coal specimen infiltrating into the plasma flame, which brings about an increase in the quantity of acetylene generated. It is found after all that the conventional acetylene yield of 34g/kWh increases to 59g/kWh in a rapid quenching test in which the specimen is dried Akabira coal and the plasma is an argon gas plasma containing 40% hydrogen.

    With objectives of saving energy and reducing greenhouse gas emission at the Pridneprovskaya power plant in Ukraine, a scrap and build project has been discussed. This project will abolish the unit No.12 among the eight units in the existing coal burning power generation facilities, and install a natural gas burning combined cycle plant comprising of three units each with an output of 100 MW. The new plant facilities will consist of gas turbines, steam turbines, HRSG and auxiliary devices, and an air-cooled synchronous power generator with a capacity of 119 MVA. Use of natural gas as fuel reduces generation of soot, sulfur oxides, nitrogen oxides, and CO. In addition, the hot effluent and waste liquor effluent will decrease from those at the present plant. The required fund will be 30,107 million yen. The energy saving effect of this project is reduction of about 7.5 million tons of crude oil equivalent as a total in 40 years. The greenhouse effect gas will decrease by about 39 million tons as a total in 40 years. The profitability estimation calls for the number of investment recovery year of 16 years, and internal profit rate of 7.32%, wherein the implementation of the project cannot be expected as a project to be carried out by private funds.

    This project aims to carry out the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) protocol. With help of the most advanced technologies, the facilities of the above-named Turkmenian plant will be replaced by high efficiency gas turbine combined cycle power generation facilities for an increase in output (Block-1 to 220MW first and then Block-2 to 330MW 11 years later). For the 35 years following the modification, fuel consumption will be reduced by 734,632TJ or 17.24-million tons in terms of oil at a reduction rate of 42.79% and, as for greenhouse gas, CO2 gas will be reduced by 41.21-million tons at a reduction rate of 42.79%. This project and associated construction work demands 335,850-thousand US dollars in total. As for cost performance under these conditions, energy 0.051 tons in terms of oil and 0.1227 tons of greenhouse gas will be reduced for every dollar expended for modification. The FIRR (financial internal rate of return) is calculated on the basis of data collected at the site. In the absence of emission tradings over the reduced amount of CO2, FIRR is 2.51%, and, at this level, the project will be barely feasible in the presence of soft loans from, for example, the Japan Bank for International Cooperation.

    This project is a feasibility study to get effects of reducing greenhouse effect gas by repairing Units 8, 9, and 10 (330MW in total) of Schekinskaya thermal power plant and Units 1-7 (450MW in total) of Novomoskovskaya thermal power plant. Both are very old brown coal fired thermal power plants which were constructed during 1947-1967. At present, they are run fired by natural gas. Being very superannuated, they need repair of the facilities. In the adjustment of opinions with Russia, the plan was aimed at substantial reduction of greenhouse effect gas by increasing thermal efficiency of power plant. For it, a 800MW class gas turbine combined cycle power plant is constructed at Novomoskovskaya power plant where there are existing buildings and space for equipment and where gas fuel can be used. As a result of the study, it was indicated that the reduction amount of greenhouse effect gas after the repair becomes 1,853,966 tons/yr as against 3,590,514 tons/yr before the repair. (NEDO)

    This research aims at development of efficient lighting sources using high-brightness white LEDs. 4 research programs are as follows: (1) Basic study on emission mechanism and crystal growth, (2) Improvement of epitaxial growth methods for blue and ultraviolet LEDs, (3) Substrates for homoepitaxial growth, and (4) Basic properties of white LED lighting sources. The research results are as follows. The emission mechanism was clarified both in InGaN epitaxial layers and quantum-well structures by means of ultra-fast time-resolved spectroscopy linked with femto-second laser and the dependence of magnetic and electric fields. For reduction of a lattice defect density, an optimum thin-film crystal growth method was developed. As a new growth method of bulk single crystal substrates, a low-pressure vapor-phase growth method using radical nitrogen plasmas was developed to study synthesis of GaN and formation of single-crystal GaN. The prototype LED lighting source was prepared by using the white LEDs of 8 lm/W supplied from this project for basic study on its electric and heat radiation characteristics, and a light-guiding plate system.

    Discussions were given on the modification plan for Khabarovsk Thermal Power Plant as part of the basic survey on promotion of joint project implementation based on the COP3. The plan calls for shutting down the overaged power plant No. 1 (462.5 MW) and newly building the power plant No. 4 with high efficiency to reduce CO2 emission. The plant will use coal, which is mined extensively in the region. The plant will be a combined heat and power plant with a total power generation output of 576 MW and a total thermal output of 1140 Gcal/h. Effect of reducing CO2 emission as the result of this modification plan will be as much as about 1.2 million tons annually. The plant will use coal as fuel in the beginning, but if it uses natural gas in the future, for which pipeline construction from Sakhalin has been planned recently, the CO2 emission reducing effect will reach 2.4 million tons. Internal profitability was calculated with the CO2 price set at zero US dollars and with the foreign exchange rate varied, for a case of firing coal for 30 years. The profitability may vary largely according to the foreign exchange level, such as profit rate of 5.47% at 20 roubles to a US dollar, 11.04% at 12 roubles, and 21.22% at 6 roubles. The profitability should be judged somewhat low under the current exchange rate of 20 roubles to a dollar. Financial provision with a favorable condition is strongly desired. (NEDO)

    R and D was conducted for the purpose of developing the alternative natural gas manufacturing process that, using coal as the raw material, is highly efficient as well as environmentally superior, with the fiscal 1998 results reported. A hydrogasification test was conducted on Taiheiyo coal at a temperature of 1,173k and a pressure of 7 MPa, which showed that all gaseous products other than methane stopped their evolution roughly in the heat-up process, while methane continued to evolve to show the highest yield. In the reactivity comparison of various types of coal, coals with carbon content of 80% or below were high in reactivity and considered suitable for hydrogasification feedstock. It was also suggested that the hydrogasification reactivity of low rank coals including sub-bituminous coals or below might be greatly affected by the presence/absence of the catalytic effects of ion-exchanged metals. Behavior experiments of sulfur and nitrogen in coal in the hydrogenation reaction were carried out using a continuous free-fall type reactor, which elucidated the effects of hydrogen pressure and gas residence time among various operational elements.

    This is a feasibility study desired to connect to a joint implementation program in the future, which plans to modify the oil refining system now in existence at the NORSI Refinery in the Russian Federation. The modification plan for energy efficiency improvement consists of (1) the reconstruction of the heat exchanger network, addition of three high-efficiency heating furnaces, and the introduction of stripping steam into the pre-distillation tower for the atmospheric/vacuum distillation system, (2) the addition of two combined heat exchangers, replacement of the reboiler with a steam reboiler, and the use of reflux line in the deethanization tower for the reforming section of the catalytic reforming unit, and (3) the addition of combined heat exchangers and the installation of two high-efficiency heater furnaces for the hydrodesulfurization unit for kerosene and light oil. The plan requires 40,470,000 dollars, and will save 48,000 tons/year in terms of oil and reduce CO2 emissions by 120,000 tons/year. No settlement has been reached, however, about financing, agreement to cost performance, or apportioning of the amount of reduction in CO2 emissions to the parties involved in case of transfer under a joint implementation program.

In the survey, studied were measures to increase production, measures to prolong the plant life, energy conservation measures and environmental measures. As a result of the study, it was confirmed that if the production amount targeted at first is recovered and the consumption amount of natural gas can be reduced down to the original target by rehabilitating the superannuated equipment/machines and by supplying/preparing the spare parts in shortage, the reduction in greenhouse effect gas emission is achieved and the production cost of urea fertilizer is lowered. Further, it was found that by carrying out this, energy efficiency can be heightened at the parts which can be replaced with the newest processes. The energy conservation amount calculated was 25,890 toe/y, and the amount of greenhouse effect gas reduction 60,448 t-CO2/y. The investment amount was approximately $19,106,000. The total interest is to be raised by soft loan, and the internal earning rate was 9.04% with the present prices of natural gas and urea. (NEDO)

    Test and research are conducted for acquiring basic data regarding coal gasification. In the basic research for the development of a high-calorie gas production process, a small moving bed gas furnace is improved, and a high-calorie gas of a heating value of approximately 5,100kcal/m{sup 3} is stably produced at a rate of approximately 20m{sup 3} per diem. The carbon conversion rate turns out to be approximately 37% for the gas, approximately 53% for the residual char, and approximately 10% for a mixture of tar, naphthalene, benzene, phenol, etc. Hydrogen is produced making use of the residual char when a small amount of coal is added, and it is deemed that the first experiment for the development of a moving bed hydrogasification process has been successfully completed.

    In view of the prospective demand for coal in China and of the current state of transportation, a development plan is formulated for Tangkou Mining Area (of model mines) for the purpose of realizing efficient exploitation of coal. The infrastructures for coal transportation are complete in this area, and delivery of coal is easy from this area to the coal demanding regions. Although coal seams are quite deep in the ground, the important ones contain rich reserves. Exploitation is carried out under a vertical shaft scheme, in which pits extend horizontally at the level of 950m below the sea surface. As for production, an annual yield of 3-million ton is predicted thanks to two compositely mechanized coal faces. Coal is won by the monolayer side hole method in the case of seams not thicker than 4.0m, and by the caved stope method in the case not thinner than 4.0m. Employed for the mines are 1077 people. Operation days are 300, efficiency 15t/man/shift. The annual sale in total is expected to be worth 759-million 534.6-thousand yuan. To be required for the construction will be 1.2-billion yuan for mines and 0.2-billion yuan for coal dressing facilities, or 1.4-billion yuan in all, and the figures indicate that the plan is economically promising. 43 figs., 119 tabs.

    With an objective of using practically the coal hydrogasification technology (the ARCH process), developmental research has been performed on important elementary technologies using different experimental devices. This paper summarizes the achievements in fiscal 1999. In the research by using a small testing apparatus, the Taiheiyo coal was used to have performed demonstration operation on the replacement natural maximized case, the heat efficiency maximized case, and the BTX maximized case. As a result, the three cases were found nearly as anticipated in the simulation, whereas the replacement natural gas maximized case has achieved the targeted whole coal conversion rate of 60% or more. However, the BTX maximized case presented a value lower than the targeted BTX yield of 12%. In the developmental research on the injector, the injector having been fabricated for the hot model test was given another combustion test, where the focal temperature of 1,200 degree C or higher was derived. The hot model test has verified the non-agglomeration performance of coal by using as parameters the focal temperatures, coal cross sectional area loads, coal types, and injectors. It was verified that the Taiheiyo and Shin Mu coals do not agglomerate excessively. (NEDO)

    With an objective to evaluate feasibility of practical use and economy of the coal hydrogasification technology (the ARCH process), survey and research have been performed. This paper summarizes the achievements in fiscal 1999. In the survey on the social acceptability, survey has been made on the future trend in the demand and supply and the price of LNG, LPG, and coal for hydrogasification. As a result, it was discovered that the price of LNG imported into Japan is determined as if linked with the crude oil price, and Saudi Arabia is the price leader of the LPG price. With respect to the survey on the possibility of international cooperation, surveys were conducted on the prospects of the long-term demand and supply in China, natural gas resources, and the demand and supply thereof. The feasibility study has estimated the product gas manufacturing cost after the process has been improved. In the trial calculation on the three-mode cost, it was discovered that, although the profit from byproducts is great, the BTX maximized mode causes the manufacturing cost to be higher by as much as 2 to 3 yen per Nm{sup 3} than that of other modes because of higher unit consumption in raw materials and higher construction cost.

    A report was made on the result of investigation for selecting a suitable site for a coal gasification pilot plant. The high calorie gasification plant under the Sunshine Project is scheduled to have a parallel operation of two methods. It could be decided on one only method depending on the future studies. One is the 'water gasification method' using coal only as the raw material, with hydrogen gas added to contrive methanization. The other is the 'hybrid gasification method' using mixed slurry of powdered coal and heavy oil as the raw material, with oxygen supplied to it to form a clean gas. The sites proposed for the pilot plant are the cities of Yubari, Iwaki, Kita-Ibaraki, Tagawa, Iizuka and Imari. The items for assessment of cost effectiveness are the expenses of development of a site, road construction, removal of existing obstacles, plant construction, power receiving equipment construction, irrigation supply facilities construction, wastewater treatment system construction, ash discharging system construction, transportation, and supply/processing-related maintenance. As a result of the assessment, Iwaki city was picked up as the area almost free from drawbacks to cost effectiveness. (NEDO)

    This paper describes investigation and discussion on effects of introducing a superconductor power application technology. The generator sub-committee has compared features, technical problems and development expenses in the first and second proposals, but has not reached the final conclusion. The first proposal is targeted for early realization of 200-300 MW class generators with development cost of six to seven billion yen and a development term of seven years. These developments raise largely towards practical application the levels of material technologies, fabrication and processing technologies, and analysis and design technologies. The second proposal is intended of developing 200-300 MW class generators targeted for increased diameter, as a reduced size machine of a 600-MW generator being a future generator. It will take development cost of eight to nine billion yen with the period of nine years for the development. Majority of the technologies required for developing the future 600-MW class generator can be demonstrated. The AC superconductor device sub-committee has investigated design examples, clarified the specification requirements, and investigated and studied the development measures. The oxide superconductor sub-committee has investigated and studied making wires and conductors, and device application feasibility, but has not reached the stage of presenting specific research and development methods. The practical application strategy sub-committee has also not been able to present a collective measure because of difficulty of making future prospect on the electric power business. (NEDO)

    For the purpose of conserving energy and reducing greenhouse effect gas emission, survey was conducted on a project for recovering waste heat from the cement production process and using it for power generation in India. In India, the production amount of cement has steadily been increasing in and after the complete liberalization of the cement industry in 1989, and now the production amount is second in the world. Duties of approximately 25% are imposed on the import of the cement waste heat equipment, which is still a high-rate tariff. The India Cement Co., which is a candidate local company for this project, is a typical cement company in an excellent financial state in India. As to the economical efficiency of the project, economical effects are very good as seen in the internal earning rate of more than 30% and the period of ROI of less than 4 years, even if high-rate duties of India are imposed. There seems to be a great possibility of the spread of the related technology in the light of the following reasons: the situation of electric power in India is not good, reduction in production cost is being urgently requested due to the drop in cement price, and the equipment in this project is clean equipment using waste heat and therefore meets with the policy of the Indian government in which emphasis is placed on the environment.

    A research study was done on MHD generation by coal gasificating combustion. MHD generation is a very attractive power generation system such that efficiency is as high as 55%, that preservation of the environment is superior, and that coal can be used as fuel. The open cycle seems suitable for a one million kW class as a base load following up load fluctuation of approximately 20%, while the closed cycle for 200-300 thousand kW class doing daily start-stop. With a mind to a scale of 30 MWt, in the open cycle, R and D is required in such items as a coal gas combustor, generation channel, high temperature air heater, and seed/slag recovery device. In the closed cycle, R and D is required in the generation channel, high temperature helium heater/high temperature valve, seed injection/recovery device, operation technique of helium closed loop, etc.. Moreover, as a total system, development is necessary in the areas of conceptual design and optimization method, partial load operation and DSS operation method, for example. (NEDO)

    With an objective of saving energy and reducing greenhouse gas emission, discussions have been given on improvement measures for lighting equipment in the Sao Paulo State Primary Schools in the Federative Republic of Brazil. Measures for the energy saving are composed of modification to high-efficiency lighting equipment using electronic ballasts, high-efficiency fluorescent lamps, and reflectors, and introduction of control systems using lighting control sensors. In the survey, taking up 3,000 schools as the objects of implementation, a project scheme was established that the energy saving measures will be introduced, and the investment cost will be recovered by concluding the ESCO service for five years, after which the school side enjoys the profit for five years. As a result of the discussions, the total project cost will amount to 2.82 billion yen, with which the energy saving quantity would be 7,636 tons annually as converted to crude oil, or 114,540 tons during a period of 15 years as the achievement of the project as a whole. Greenhouse gas emission would be reduced by 7,397 t-CO2 on an annual average, or 110,949 t-CO2 in the project as a whole. Discussions on the profitability revealed that the internal profit rate can be calculated as 15.73%, indicating that the profitability can be envisaged. (NEDO)

    As to the development of coal use hydrogen production technology, the paper made the test study on the improvement of gasifier use materials and evaluation of the characteristics, the evaluation test in the environment using the actual machine, etc., and the FY 1993 results were reported. The results of the study were as follows. Concerning the shaped refractory for gasifier hearth, it was found that high chromia base and picrochromite base refractory development materials had much more excellent coal slag resistance than other existing component-system materials. It was shown that the development materials began to deteriorate under the coal gasification environment at temperatures of about 1,500 degrees C or higher. As to the mullite ceramics, a possibility was shown of improving the slag permeation resistance by making the crystal grain coarse by long-time sintering. By the survey of the state of damage of the proposed materials (refractory and iridium) used in the operational environment of the pilot plant, the outlook for use limit was made clear. In the environment test using the actual machine on the proposed metal base alloy of the typical equipment of the pilot plant, the correspondence between the operational environment and material corrosion was made clear.

    Discussions have been given on the improvement and modification project intended of saving energies and reducing greenhouse gas emission in the Potoshani district heating and heat supplying facilities in Romania. Thirty years have elapsed since the building of the Potoshani district heating and heat supplying facilities, whereas noticeable energy loss has occurred due to aged deterioration, such as thermal efficiency decrease, performance decrease, and hot water leakage due to piping corrosion. The present project is intended to improve the heat production and power generation facility efficiencies, and reduce the heat loss in heat transportation and distribution to less than 5%. The improvements will be implemented by replacing and rehabilitating the existing boilers, replacing the turbine generators, and replacing the transportation and distribution pipelines and heat exchangers. As a result of the discussions, the present project is estimated to result in annual fuel conservation of 35,820 tons of crude oil equivalent, and annual reduction of the greenhouse gas emission of 110,835 t-CO2. The total amount of the initial investment for the project would be 11.369 billion yen, and the payback period would be 12 years. The project will produce profit of 31.358 billion yen in 20 years, thus the project is financially feasible. (NEDO)

    As to the implementation of 'the model project for effective utilization of blast furnace gas pressure energy' and the possibility of spreading the said technology, survey/study were conducted, and the results were reported. The enterprise implementing the model project, Steel Authority of India Limited (SAIL), has been investing a total of 300 billion yen in modernizing facility/equipment after the liberalization in 1992, which is a cause of a large amount of deficit. About SAIL' cash flow, it is expected that SAIL will go into the black after tax in and after 2002. Local financial institutions are careful in investing in the iron/steel industry, but they have no problems in their own financing ability. In the evaluation of economical efficiency on the commercial basis, it is difficult to implement this model if using power prices, customs duties and borrowing rates in India as conditions. However, when preferential measures such as the exemption from taxation and help to borrowing rates are taken for energy conservation facility/equipment and the cost reduction is realized by technical cooperation, etc., it will be possible to recover the investment in 5 years. As to the possibility of spreading this model, the blast furnace with a capacity of 1000{sup 3} or more is targeted, and the number of the targeted blast furnace is 23. (NEDO)

    With an objective of using practically the coal hydrogasification technology (the ARCH process), developmental research has been performed on important elementary technologies using different experimental devices. This paper summarizes the achievements in fiscal 1998. In the research by using a small testing apparatus, the Taiheiyo coal was used to have derived hydrogasification data (distribution and yield of the reaction products) in case of having changed the reaction pressure, temperature rising rate, and H{sub 2}/caoal ratio, and to verify the possibility of increasing the BTX yield by installing a temperature zone in two steps. In the developmental research on the injector, a combustion test and a coal feeding test were performed on the injector having been designed and fabricated in the previous fiscal year to verify the basic performance and evaluate the heat resistance and durability. With respect to the hot model test, a test installation was completed with the injector mounted to conduct the trial operation and test. In addition, development was conducted on the coal temperature rise simulation as the second phase of developing the simulation of mixing of coal with high-temperature hydrogen and temperature rise.

    Having the Mining Industry Restructuring Public Corporation located in the city of Katowice, Poland as the counterpart, a feasibility study has been executed on a project to utilize coal bed gas for power generation. Selected for the study are the 'Budryk coal mine' owned by KWK 'Budryk' Coal Company and the 'Pniowek coal mine' owned by Jastrzebie Coal Company. Since the Pniowek coal mine can utilize the whole quantity of recovered methane by 2001, the Budryk coal mine was selected as the object of the project. As a result of the trial calculation on the economy when the new gas power plant is installed in the Budryk coal mine, the energy substitution effect was found to equal to a power amount at transmission terminal of 6 MWh/year. Furthermore, when proliferation effect is taken into consideration, an enormous effect can be expected if new coal mines are developed and the existing cola mines will go further deeper, because the Silesian coal mine presently has the coal resource quantity of 57 billion tons and the annual gas discharge quantity of 750 million m{sup 3}. Therefore, if the technologies to recover, manage and utilize the gas are established at the Budryk coal mine, a large effect leading to an aspiration would be expected under the current situation of the structural reorganization under which the Polish coal companies are placed.

    As to the development of coal use hydrogen production technology, the paper studied the reactivity of char and ignition characteristics of various coals in the use of electric furnace and the participation in pilot plant test and the improvement, and the FY 1993 results were reported. In the study of reactivity of char, it was found that the reactivity was the same, regardless of the equipment and kind of raw coal, if considered of the ratio of the total oxygen amount (the char-containing oxygen amount added to the oxygen supply amount) to the carbon supply amount in char. In the test on ignition characteristics of overseas coals, the same characteristics as those of the Taiheiyo coal conventionally tested were obtained and it was found that it was good to use the same method for start-up of gasifier as conventionally used. In the pilot plant test in the previous year, slag and ash stuck to the outlet of the gasification part and heat recovery part and developed, which hindered the continued operation. To improve it, the following were carried out: model study, study of ash sintering, study using the synthetic test equipment, analysis of the deposit in gasifier, etc. Based on these results, the plant was improved, and the continued operation of 1,149 hours was stably achieved in RUN8.

    A report was made on the result of investigation for selecting a suitable site for a coal gasification pilot plant. The high calorie gasification plant under the Sunshine Project is scheduled to have a parallel operation of two methods. It could be decided on one only method depending on the future studies. One is the 'water gasification method' using coal only as the raw material, with hydrogen gas added to contrive methanization. The other is the 'hybrid gasification method' using mixed slurry of powdered coal and heavy oil as the raw material, with oxygen supplied to it to form a clean gas. The sites proposed for the pilot plant are the cities of Yubari, Iwaki, Kita-Ibaraki, Tagawa, Iizuka and Imari. The items for assessment of cost effectiveness are the expenses of development of a site, road construction, removal of existing obstacles, plant construction, power receiving equipment construction, irrigation supply facilities construction, wastewater treatment system construction, ash discharging system construction, transportation, and supply/processing-related maintenance. As a result of the assessment, Iwaki city was picked up as the area almost free from drawbacks to cost effectiveness. (NEDO)

    Surveys and studies were conducted for establishing methods for evaluating solar cell performance and reliability. In the effort to develop basic technologies for the comprehensive evaluation of the performance of various types of solar cells and modules, an ultrahigh matching solar simulator and a large area solar simulator were built. The long-term exposure tests of solar cell modules kept on at 5 sites in Japan, 3 sites in Australia, and 1 site in Oman, and the databasing of the test data was planned. In the long-term evaluation of solar cell durability, investigations centered about module deterioration, where abnormal heat generation was observed, cause of increased resistance was inspected, and separation between the cell and the filler was examined. In the development of an accelerated photodegradation test method, it was found that the result of a light-dark cycle test with the ambient temperature varied agreed excellently with the results of outdoor exposure tests. It was consequently proved that the light-dark cycle test was a very promising candidate for an accelerated photodegradation test for a-Si solar cells. (NEDO)

    A research is conducted to find out if efficiency will increase and greenhouse gas will decrease when fuel is changed from coal to gas at the above-named plants, and the economics of the plan is reviewed. The No. 1 plant comprises 18 coal-fired boilers with a total design capacity of 2985 tons/hour, and 8 steam turbine generators rated at 185MW, constructed in the 1940s. The No. 9 plant was constructed in the 1960s and 1970s. Four different modifications programs are drafted to study the fuel change plan. As the result, it is found that the addition of natural gas burning facilities to the existing heat and power co-generation plants and the modification of the existing boiler-related facilities will be low in earning rate and reliability, though excellent in budget size and cost efficiency; and that to dismantle the existing plants and to newly construct heat and power plants operating on gas turbines will bring about a higher earning rate, fuel cost reduction effect, and reliability, though such will cost more.

    For the preparation of a proposition concerning future research and development, surveys and studies were conducted centering about efficiency enhancement and cost reduction for the next generation ultrahigh-efficiency solar cell system. For improving the efficiency of the crystalline compound solar cell, studies were made about the prospects of the embodiment of a 3-junction and 4-junction types and of an increase in conversion efficiency expected to realize thanks to their light condensation behavior. It was inferred that anticipation of 29-47% conversion efficiency in 1 to 4-joint cells was theoretically acceptable. Four-joint structure cell fabrication would be a challenging task but would bring about an conversion efficiency of approximately 47% thanks to enhanced light condensation capability. As for cost reduction through the use of light condensation technology, surveys of overseas trends showed that the condensation-enhanced photovoltaic power system was characteristically fit for lower-price production. As for condensation and tracking systems, studies were made about cost calculation models of organizations involved in the United States and Europe, and then it was found that cost reduction in the optical system for condensation and in the tracking mechanism would be mandatory for the achievement of 75 yen/W.

    Research and development was carried out for the production of a Cu(InGa)Se{sub 2}-based thin-film solar cell submodules, having a conversion efficiency of 13% and an area of 30 cm times 30 cm, at a cost of 140 yen/Wp (at a production rate of 100 MW/year). In the effort to fabricate a large-area photoabsorption layer, reproducibility was improved by the introduction of a technique for controlling the Cu/III group ratio in and the thickness of the metal precursor film by the use of ICP (inductively coupled plasma) analysis. A maximum conversion efficiency of 12.93% and a reproducibility of 85% were achieved, which meant that the production cost goal was achieved. In the effort to develop a high-resistance buffer layer fabrication technology, a fabrication method was developed in which a lower limit was specified for solution transparency enabling the completion of the film fabrication process with no colloid formation occurring in the solution. For preventing the high-resistance buffer layer fabrication process from growing too complicated, the steps were integrated into one for the MOCVD-ZnO:B window layer. As the result, the film fabrication process subject to the film fabrication control based on solution transparency was simplified for a great increase in reproducibility. (NEDO)

Analyzed subjects were 653 Japanese OSA patients (619 males and 34 females treated with CPAP at a sleep laboratory in a respiratory clinic in a Japanese city. Based on Bandura's social cognitive theory, the CPAP Self-Efficacy Questionnaire for Sleep Apnea in Japanese (CSESA-J was developed by a focus group of experts, using a group interview of OSA patients for the items of two previous self-efficacy scales for Western sleep apnea patients receiving CPAP treatment. CSESA-J has two subscales, one for self-efficacy and the other for outcome expectancy, and consists of a total of 15 items. Content validity was confirmed by the focus group. Confirmatory factor analysis showed that the factor loadings of self-efficacy and outcome expectancy were 0.47–0.76 and 0.41–0.92, respectively, for the corresponding items. CSESA-J had a significant but weak positive association with the General Self-Efficacy Scale, and a strong positive association with “Self-efficacy scale on health behavior in patients with chronic disease.” Cronbach’s alpha coefficient was 0.85 for the self-efficacy subscale and 0.89 for the outcome expectancy subscale.
