    For contributing to the formulation of technology development programs, an analysis is conducted based on the concept of value web into which the economic spread effect is incorporated. As information technology plays an important role in the fields of automobiles and chemical materials, there are various fields the research and development efforts exerted in which are common to many others. As to what additional values are created when such separately developed technologies cross each other, a discussion is conducted using techniques of industry-oriented analyses. Findings obtained are mentioned below. When the numbers of essays relative to the respective industries are compared, it is found that 63% of the total number of biotechnological essays fall on agriculture, the drug industry, and the food industry. On the other hand, when it comes to the produce, related industries larger in marketing scale is more strongly influenced by the spread effect. The spread effect of biotechnology is distinguished in the drug industry, and that of information/communication technology in the information industry, electric and electronic industries, and in the semiconductor industry.

    Asian economies hit by the currency crisis in 1997 are still in struggle to recover their growth and to boost again their exports. Although several short-term policy measures to stimulate the demand- side of the economy is certainly necessary, in a longer-term perspective, the key to real recovery would exist in their ability to absorb foreign technologies through trade and/or FDI, as stressed by recent new theories of growth and trade. This paper examines empirically the role of technology diffusion from advanced countries to total factor productivity (TFP) and export competitiveness in four major East-Asian countries: Korea, Singapore, Malaysia and Indonesia, three of which were seriously damaged by the currency crisis. Our major findings are summarized as follows. First, we found that technology acquisition from abroad is quite important for TFP growth of most industries in Asia, in particular for two ASEAN countries (Malaysia and Indonesia), while such productivity impact from foreign technology was relatively small for Korea and Singapore. Second, the impact of technology diffusion was much larger in that through trade than in that through foreign direct investment. Some FDI practices to preclude technology access for developing countries might explain such weaker role of FDI on TFP. Third, the nexus between TFP and export competitiveness was surely positive, in particular for industries of high export performance. However, the magnitude of impact was relatively small in Korea, in spite of its overwhelming productivity performance. (author)

  4. Koka: Programming with Row Polymorphic Effect Types

    Full Text Available We propose a programming model where effects are treated in a disciplined way, and where the potential side-effects of a function are apparent in its type signature. The type and effect of expressions can also be inferred automatically, and we describe a polymorphic type inference system based on Hindley-Milner style inference. A novel feature is that we support polymorphic effects through row-polymorphism using duplicate labels. Moreover, we show that our effects are not just syntactic labels but have a deep semantic connection to the program. For example, if an expression can be typed without an _exn_ effect, then it will never throw an unhandled exception. Similar to Haskell's `runST` we show how we can safely encapsulate stateful operations. Through the state effect, we can also safely combine state with let-polymorphism without needing either imperative type variables or a syntactic value restriction. Finally, our system is implemented fully in a new language called Koka and has been used successfully on various small to medium-sized sample programs ranging from a Markdown processor to a tier-splitted chat application.

    Full Text Available Effective management is essential for small-scale fisheries to continue providing food and livelihoods for households, particularly in developing countries where other options are often limited. Studies on the population dynamics and stock assessment on fishery target species are thus imperative to sustain their fisheries and the benefits for the society. In Lake Koka (Ethiopia, very little is known about the vital population parameters and exploitation status of the fishery target species: tilapia Oreochromis niloticus,common carp Cyprinus carpióand catfish Clarias gariepinus.Our study, therefore, aimed at determining the vital population parameters and assessing the status of these target species in Lake Koka using length frequency data collected quarterly from commercial catches from 2007-2012. A total of 20 097 fish specimens (distributed as 7 933 tilapia, 6 025 catfish and 6 139 common carp were measured for the analysis. Von Bertalanffy growth parameters and their confidence intervals were determined from modal progression analysis using ELEFAN I and applying the jackknife technique. Mortality parameters were determined from length-converted catch curves and empirical models. The exploitation status of these target species were then assessed by computing exploitation rates (E from mortality parameters as well as from size indicators i.e., assessing the size distribution of fish catches relative to the size at maturity (L m,the size that provides maximum cohort biomass (Lopt and the abundance of mega-spawners.

    The Ethiopian Rift Valley Lakes (ERVLs) are water resources which have considerable environmental, economic and cultural importance. However, there is an increasing concern that increasing human activities around these lakes and their main inflows can result in increased contamination of these water bodies. Information on total concentrations of some trace elements is available for these lakes and their inflows; however, data on the trace element speciation is lacking. Therefore, the objective of this study was to determine the low molecular mass (LMM) trace element species and also, evaluate the influence of flooding episodes on the LMM trace element fractions. At-site size and charge fractionation system was used for sampling of water from the lakes Koka, Ziway and Awassa and their main inflows during the dry and wet seasons. The results showed that chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and lead (Pb) in Lake Koka and its inflows as well as in Lake Ziway were predominantly present as HMM (high molecular mass, i.e., > 10 kDa) forms, while arsenic (As), selenium (Se), cadmium (Cd) were more mobile during the dry season. In Lake Awassa, all except Cr and Mn were predominantly found as LMM species (low molecular mass, i.e. < 10 kDa) which can be attributed to the high concentrations of LMM DOC (dissolved organic carbon). During the wet season, results from the Lake Koka and its inflows showed that all trace elements were predominantly associated with HMM forms such as colloids and particles, demonstrating that the mobility of elements was reduced during the wet season. The colloidal fraction of elements such as Cr, Ni, and Cd was also correlated with dissolved Fe. As the concentration of LMM trace element species are very low, the mobility, biological uptake and the potential environmental impact should be low.

    Demand side management through a pricing mechanism, that is the indirect load control was experimented to analyze the pricing effect. When power consumption in indirect load control groups is compared between peak time band in weekdays in summer and off-the-peak time band, the power is less consumed when price gap is set than in a uniform charge time. When more number of persons is in home in daytime, room cooling is used in daytime including the peak band to adjust the demand. The substitution elasticity in price between demands in the peak time band and the off-the-peak time band is from about 0.06 to 0.07, which cannot be ignored. If the peak price is increased by four times, the demand in the peak band can be reduced by about 0.15 kW (when average power demand per household is assumed 0.75 kW). For room cooling devices, the first device is often installed in a living room and the second and further units in individual rooms such as bed rooms. The more the number of device, the higher the possibility that the use time band is outside the peak time band. This indirect load control experiment is a field test related to the peak-activated pricing for small power users, by which the users` behavior against the pricing effect was identified quantitatively. 5 refs., 1 fig., 8 tabs.

    Heavy metal accumulation in agricultural crops has grown a major concern globally as a result of a significant health impact on human. The quantification of heavy metals (Cd, Pb, Cr, Zn, Cu, and Ni) in the soil and vegetables at two sites (Koka and Wonji Gefersa) was done using flame atomic absorption spectrophotometer. The mean concentrations of heavy metals in vegetable fields' soil samples obtained from Koka were higher for Pb, Cr, Zn, Cu, and Ni. The overall results of soil samples ranged 0.52-0.93, 13.6-27.3, 10.0-21.8, 44.4-88.5, 11.9-30.3, and 14.7-34.5 mg kg -1 for Cd, Pb, Cr, Zn, Cu, and Ni, respectively. The concentrations of heavy metals were maximum for Cd (0.41 ± 0.03 mg kg -1 ), Pb (0.54 ± 0.11 mg kg -1 ), Zn (14.4 ± 0.72 mg kg -1 ), Cu (2.84 ± 0.27 mg kg -1 ), and Ni (1.09 ± 0.11 mg kg -1 ) in Cabbage and for Cr (2.63 ± 0.11 mg kg -1 ) in green pepper. The result indicated that Cd has high transfer factor value and Pb was the lowest. The transfer pattern for heavy metals in different vegetables showed a trend in the order: Cd > Zn > Cu > Cr > Ni > Pb. Among different vegetables, cabbage showed the highest value of metal pollution index and bean had the lowest value. Hazard index of all the vegetables was less than unity; thus, the consumption of these vegetables is unlikely to pose health risks to the target population.

    The concentrations and bioaccumulation of persistent organic pollutants (POPs) were determined in four fish species from Lake Koka, Ethiopia, representing 2-3 levels in the food chain of the lake. Dichlorodiphenyltrichloroethanes (DDTs), endosulfans, polychlorinated biphenyls (PCBs) and chlorpyrifos were identified, with DDTs as the most predominant pesticide, with concentration ranging from 0.05 to 72.53 ng g{sup -1} wet weight (ww). All fish tissue samples collected from different species of the lake contained residues of DDTs. The maximum level of DDTs was found in the fattiest, African sharptooth catfish (Clarias gariepinus) sampled from the lake, with a mean concentration of 15.15 ng g{sup -1}ww. The significant (P < 0.05) relationship between concentrations of DDTs and {delta}{sup 15}N indicates that DDTs biomagnified in the food web of the lake. The 4,4 Prime -DDE to 4,4 Prime -DDT ratio in Oreochromis niloticus (0.6) and Cyprinus carpio (0.5) were below 1, indicating ongoing use of DDTs in the study area and recent exposure of these fish species.

    To obtain the basic data to develop instruments for diagnosis of atherosclerosis and to elucidate the mechanisms of atherogenesis by focusing on the autofluorescence of blood and vascular walls of atherosclerotic animal models and human patients. We have performed experiments to examine the relationships between autofluorescence of blood and vascular walls of guinea pig atherosclerotic model and human patients and obtained the following results. 1. The autofluorescence from human atherosclerotic aorta included the components with longer wave length than normal aorta, suggesting that diagnosis of atherosclerotic aortic walls will be possible using spectroscopic analysis through glass fiber catheter into vascular system. Further studies should be needed to the quantitative diagnosis. 2. The autofluorescence from blood plasma of human atherosclerotic patients has showed that the peak wave length was shorter than that of normal plasma. This phenomenon was mainly caused by the oxidization of plasma, especially lipoproteins, LDL and HDL. 3. Atherosclerotic model of the guinea pigs was quite similar to human atherosclerosis at the points of cholesterol levels and localization of lipid deposit to arterial walls, and showed to be useful for the studies of atherosclerosis.

    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.

    Full Text Available Entomological studies to determine the effect of the physical characteristics of mosquito larval breeding water bodies and reservoir water level changes on the occurrence of Anopheles mosquito larvae were conducted in two villages at Koka reservoir in central Ethiopia between August and December 2007. Of the two study villages, Ejersa is located close to the reservoir, and Kuma is 5 km away from it. Data on the type, number and physical characteristics of Anopheles larval breeding habitat, species composition and densities of anopheles mosquitoes in and around the study villages were investigated and recorded. Meteorological and reservoir water level data were compared with availability of Anopheles larval breeding sites and densities. Entomological data, derived from weekly larval collections, showed that Anopheles pharoensis Theobald, Anopheles gambiae s.l. Giles, Anopheles coustani Laveran and Anopheles squamosus Theobald were breeding in the study area. The mean larval density of An. gambiae s.l. in this study was higher in slightly turbid and shallow aquatic habitat than in turbid and relatively deep aquatic habitat. The density of An. pharoensis in habitat with floating vegetation and with relatively shady conditions was significantly higher than that of less shaded aquatic habitat and greater emergent vegetation. There was also a positive correlation between the occurrence of Anopheles larvae with the water and daily minimum atmospheric temperature. Similarly at Ejersa, over the sampling period, there was a positive correlation between falling reservoir water levels and the number of positive breeding habitats. These results confirm that physical characteristics of the water bodies play an important role in the species composition, total Anopheles larval count, and the density of Anopheles mosquitoes. Suitable breeding habitat in the vicinity of the reservoir village was strongly associated with the reservoir. This is particularly

    In order to provide discussion materials for measures to achieve the GHG emission reduction target, investigations and discussions have been made on the following subjects: cost effectiveness of reducing GHG emission by target countries and target technologies, use of maps and databases on the possible reduction quantity of GHG emission, the targeted countries and business categories. Regarding the target countries, investigations were made on the general situation of the energy consumption efficiency, difference between their energy consumption efficiency by industries and that in Japan, and the GHG emission quantities by sectors. As a result, 31 counties hopeful in reducing CO2 emission were selected. With regard to technologies to reduce CO2 emission, technologies having been practically used and proliferated in Japan were used as the base, whereas 43 technologies were systematized for such departments as industries, business operations, households, and transportation. According to a trial calculation on the effect of CO2 emission reduction, if the 43 technologies are applied to the 31 target countries, CO2 emission reduction of 698 million tons as a whole would be possible, for which the required expense was calculated as 114.4 trillion yen. In evaluating the CO2 emission reducing technologies, the cost effectiveness of each technology was evaluated by cost per GHG emission reduction of 1t-CO2. (NEDO)

    The present investigative research is intended to grasp the whole image of cost effectiveness of the energy saving and new energy technologies to suppress and reduce CO2 emission in Japan. Furthermore, the research considers the cost effectiveness and discusses the efficiency and the directionality of reducing CO2 emission from an estimation of the social introduction cost of individual technologies and quantity of CO2 emission reduction. These activities are intended to provide the fundamental items of information when discussing the measures to achieve the emission reduction target imposed on Japan. The research divides the whole aspect into energy conversion, industrial, consumer and transportation departments for discussion, and calculates the technological items that can be introduced by 2010 and the quantity of the introduction thereof, as well as the effect of reducing CO2 emission. Calculations are also performed on 27 elementary technologies in total and the CO2 emission reducing effect, assuming technological possibilities. Subsequently, analyses are carried out from the viewpoint of cost effectiveness by departments. It is shown that the average cost effectiveness is distributed in the range from 108,000 yen/ton to 1,129,000 yen/ton. Scenarios of reducing CO2 emission are discussed from the analyses of the cost effectiveness. (NEDO)

The proliferation of suitable breeding habitats around the reservoir villages is strongly associated with reservoir water level changes. This is particularly important for A. pharoensis and A. arabiensis which are important vectors of malaria in the area.

    Trends toward power market deregulation were investigated in Japan and 16 other countries, and various deregulation models were examined and evaluated for their merits and demerits. There are four basic models, that is, franchise bidding model, competitive bidding in power generation model, wholesale wheeling or retail wheeling model, and mandatory pool or voluntary pool model. Power market deregulation has been a global tendency since the second half of the 1970s, with various models adopted by different countries. Out of the above-said models, it is the retail wheeling model and pool models (open access models) that allow the final customer to select power suppliers, and the number of countries adopting these models is increasing. The said models are characterized in that the disintegration of the vertical transmission-distribution integration (separation of distribution service and retail supply service) and the liberation of the retail market are simultaneously accomplished. The pool models, in particular, are enjoying favor because conditions for fair competition have already been prepared and because it is believed high in efficiency. In Japan and France, where importance is attached to atomic power generation, the competitive bidding model is adopted as a means to harmonize the introduction of competition into the source development and power generation sectors. 7 refs., 4 tabs.

    Fuji Electric Co., Ltd., in collaboration with Shitashion Japan and Arthur Andersen Ltd., developed a 'marketing analysis support system' which integrally analyzes evaluation factors of various dimensions explaining consumers' purchasing behaviors and which supports business for the efficient operation of product development and demand prediction. This system breaks down products into each evaluation factor from psychological and physical viewpoints, and carries out various kinds of multivariate analysis, thereby making it easy to understand visually, for example, what evaluation factors decide relative positional relations between evaluation factors or between products as well as the position of a product in the whole. Further, more precise marketing analysis and prediction become possible by visually grasping blank areas of products, extent of competition, distribution of products, composition of product series, etc. (translated by NEDO)

    Power supply services, city gas supply services, water supply and drainage services, roads, and buildings were treated as urban infrastructures so as to grasp the resources and CO2 emission consumed in their life cycle. Moreover, the consumption of resources for supporting one person and the emission of CO2 were analyzed to clarify an important point for resource saving and environmental load reduction. The resources used and CO2 emitted for each urban infrastructure were calculated with Kanto districts as a target. For the annual material weight a person, buildings are about 1,200 kg, roads are about 560 kg, and city gas is about 170 kg. Water supply and drainage is about 68 kg, and electric power is about 57 kg. For the annual CO2 emission a person, buildings are about 120 kg-C, roads are about 13 kg-C, and electric power is about 6.6 kg-C. City gas is about 5.3 kg-C, and water supply and drainage is about 4.4 kg-C. In the material weight for each resource, gravel, crushed stone, concrete, and asphalt concrete have a high consumption rate. In CO2 emission, iron, concrete, and gas oil form a high rate. 21 refs., 26 figs., 2 tabs.

    Arrangement, investigation and analysis of an energy information exchange system were conducted, with the aim of coping with the development in the whole Asia/Pacific area, the stabilization of energy supply/demand, and the environmental problem and of realizing effective cooperation of every country in the area. Concerning the trend of the domestic primary energy supply/demand, there are some patterns. Countries which show high growth rates are developing countries such as Thailand and China, and NIES such as Korea and Taiwan. Countries where growth rates are slowing down and lowering are developed countries such as Australia, Canada, Japan and the U.S. Countries where energy supply/demand is not stabilized are Singapore, Hong Kong, Indonesia and Chile which are suffering from variations in import/export. The ultimate energy consumption is the domestic primary energy supply from which the conversion loss in the conversion sector was deducted, and indicates almost the same trend as the primary energy supply. It is divided into a stabilized type of developed countries and a rapidly increasing type and a stagnant type. However, there are some exceptions. Total data in the quarter of the year cannot be the yearly data by itself, but requires a year-end tax arrangement. 40 tabs.

    For analytical evaluation of effects of environmental protection measures, energy conservation measures, new energy promotion measures, etc., a very-long term energy supply/demand model was developed and used for a simulational study. The model is composed of the models of macro economics, secondary energy prices, new energy introduction, and energy supply/demand. The feature is that the amount of new energy introduction is measuringly analyzed based on the cost and market scale, and integratedly estimated in a frame of energy supply/demand of the whole Japan. As a result of the simulation, energy source as of 2030 is composed of coal (17%), oil (44%) and nuclear power (15%) in the case of the economic growth as viewed optimistically. Contrarily, in the case of it as viewed pesimistically, energy source is composed of coal (11%), oil (40%) and nuclear power (22%). CO2 emission is -12.4% in the case of the new energy promotion than in the standard case. 7 refs., 79 figs., 107 tabs.

The model is composed of a secondary energy price model, a new energy introduction model, and an energy supply/demand model. As case parameters, selected were the price of crude oil, introduction of new energy, GDP and energy conservation, and the following cases were assumed: standard case, high price energy case, new energy introduction promotion case, low economic growth case, energy conservation case, and low energy demand case. The results of simulating each of these cases were indicated. 91 figs., 110 tabs.

    Distribution of probabilities of solar radiation fluctuation was examined to learn the fluctuation in photovoltaic power generation efficiency for the purpose of improving on the generation system. The measuring setup comprised one base station and nine terminal stations. The terminal stations were arrayed in lattice so that a 4km{times}4km-large area would be covered. The standard deviation in solar radiation fluctuation at an observation spot ANNE stayed constant at approximately 0.1kW/m{sup 2} at all observation hours. In the vicinity of a clearness index range of 0.5-0.6 (a higher index showing a clearer weather) in the daytime, the index fluctuated very much, predicting a half-clear sky with scattered cloud. In the range of 0.2-0.3, fluctuation was small. In the range of 0.6-0.7, fluctuation was small and solar radiation was stable under the clear sky. The scope of fluctuation in the areal average is smaller than that in the average at each of the terminal stations, which is explained by the even-out effect. This means that, if multiple PV systems concentratedly introduced into one region are appropriately coordinated, the outputs from the individual PV systems that are naturally inconsistent are evened out and that the reliability of the network as a whole is consequently enhanced. 5 refs., 7 figs., 1 tab.

In the simulation, assumed were a standard case, aging/hollowing case, and technical innovation case. As to macroeconomic models, macro items such as the economic growth rate, prices and IS balance were determined by giving foreign factors, financial factors, population factors, etc. In long-term energy supply/demand models, data on demand by use in commercial/residential and transportation sectors were estimated using various statistics. About the calculation result of a standard case of the former sector, the existing industries which markedly ebbed are primary products, the material system, construction/civil engineering, etc. Contrarily, the production industry such as general machines, electrical machines and automobiles increased the share. New and highly growing industries are new production industries like electronics and communication and new services like finance, insurance and communication. The GDP rate grows by 2.3% per year on average and lowers in each ten years hereafter. 53 figs., 83 tabs.

    Tar sand bitumen is petroleum-based ultra-heavy oil, and has a great amount of reserve like coal. However, there are still a lot of problems for its highly effective utilization. This paper discusses whether the light components in bitumen show independent behavior during the thermal cracking of heavy components, or not. Solvent effect and reaction mechanism during the thermal cracking are also derived from the change of their chemical structures. Athabasca tar sand bitumen was separated into light and heavy fractions by vacuum distillation based on D-1660 of ASTM. Mixtures of the both fractions at various ratios were used as samples. Negative effect of the light fraction on cracking of the heavy fraction was observed with dealkylation and paraffin formation Polymerization of the dealkylated light fraction to the heavy fraction was suggested due to lack of hydrogen in the thermal cracking under nitrogen atmosphere, which resulted in the formation of polymer. 3 refs., 6 figs.

    In order to measure sound absorption performance necessary to develop sound absorption materials, development was made on a device consisting of a small sound box capable of measurement inexpensively and easily, as a measure against the reverberation chamber method. In order to obtain stabilized diffusion sound internally, the sound box has a shape of asymmetric seven-side body in which sides do not face squarely with each other. The box was so sized that a large number of resonant vibration postures can be constituted at the targeted frequency simultaneously in the box. The box has a commercially available cone speaker with good acoustic output characteristics in frequency range of higher than 500 Hz installed on an inner side of the box. The sound source uses a method to derive sound absorption rate from difference of sound pressure levels. In order to eliminate need of averaging treatment by using a multi-point measurement inside the box, a discussion was given to provide an opening on part of the box to place the sound receiving point outside the opening. A square test piece is placed on the floor 0.5 meter or more away from the speaker in the box. As a result of the experiment, it was verified that the sound absorption rate obtained by this device corresponds well with that by the reverberation chamber method. The size of the test piece was also found adequate. 2 refs., 11 figs., 1 tab.

    Wind conditions in Arakawa Town, Niigata Prefecture, were surveyed by anemometers and anemoscopes installed at 3 different points, and the data are analyzed to develop the prediction model for investigating possibility of introduction of wind mills there. Outlined herein is power generated by fall wind by comparing predicted power availability with the actual results. In order to investigate possibility of power generation by fall wind, the wind conditions and power availability are simulated using the observed wind condition data. Predicted wind velocity involves a large error at a point where frequency of prevailing wind direction is high, and direction in which average wind velocity is high coincides with direction in which land is slanted at a high slope. Fall wind occurs locally for geographical reasons. Location of the wind mill must be carefully considered, because it is complex, although potentially gives a larger quantity of power. A wind mill of 400kW can produce power of around 600MWh annually, when it is located at the suited site confirmed by the wind condition analysis results. 6 refs., 5 figs., 6 tabs.

    This paper describes nonlinear effect recognized in Vibroseis data. Harmonics is a wave of frequency in integer factors generated in association with basic sweep vibrated by Vibroseis. Harmonics is generated because vibration in the vicinity of seismic source contains nonlinear terms. Seismic exploration using the reflection method often discusses propagation of seismic waves hypothesized as a linear phenomenon. Vibroseis data analysis, however, requires evaluation of the effect of the harmonics on accuracy. Vibroseis investigation measures may be taken by eliminating n-order harmonics by using the phase control method, and generating seismic source sweep in which the phase is shifted by 180/(n-1) each time in order to leave the basic sweep. Methods to increase the sweep length include a method to expel strain to a location outside the range of the subject travel time. Up-sweep (a sweep changing from low frequencies to higher frequencies) is also a means capable of avoiding harmonics effects. Vibroseis investigations currently performed adopt this method frequently because of it having little technological and economic problems. 10 refs., 3 figs.

    Fog samples were collected for analysis at Mt. Ohyama, the east edge of Tanzawa Mountains in the southwest of Kanto plains. Then, rainwater and aerosol that becomes the core of droplet were analyzed and measured values were compared. As a result, the pH value of the fog samples for 2 years from 1988 to 1990 ranged between 2.6 and 7.0, and the mean pH value was 3.95. According to the measurement of major component concentration of fogwater, rainwater, and aerosol, it was found that concentration of fogwater changed significantly depending on the day but every ion concentration was higher than that of rainwater. The equivalent concentration ratio of sulfuric acid, nitric acid, and chloride ions were almost equal. The concentration value of fogwater varied a lot with the course of time and became higher during the formation and the dissipation of fog. Through the analysis of such changes, atmospheric scavenging effect of precipitation of fogwater upon the trees and the earth surface was observed. It means that pollutants with high concentration were loaded on the plants and the earth surface. 23 refs., 5 figs., 2 tabs.

    In order to clarify a humification process in the early stage of coalification, the nitrogen functionality of prepared glucose-glycine condensate was studied experimentally. In experiment, the condensate was prepared by heating the mixture of glucose, glycine and water in a autoclave at 130{degree}C for 50 hours, and furthermore heating the produced solid material in water at 300{degree}C. After the condensate was hydrocracked, the fraction, condensate and hydrocracking residue were analyzed by elementary analyzer, {sup 13}C-NMR, XPS, FT-IR, capillary GC-FID/NPD and GC-MS. As a result, the glucose-glycine condensate could be arranged on the basis of three types of nitrogen such as pyridine, pyrrole and quaternary amine type. Pyridine type nitrogen increased, while quaternary amine type one decreased with an increase in heating treatment temperature. Rich pyrrole type nitrogen and poor pyridine type one were found in light nitrogen compounds in hydrocracked products. 2 refs., 4 figs., 2 tabs.

    An end use model used in the United States who is advanced in demand-side management (DSM) was used to discuss possibilities of designing and evaluating Japan`s future DSM measures. The end use model assumes energy demand based on such factors as device characteristics, meteorological data, energy prices, user characteristics, market characteristics and DSM measures. The model calculates energy demand amount by end uses basically by multiplying assumptions on device unit requirement, device retention rate, and number of users. A representative tool as an end use model that handles load shapes is the hourly electric load model (HELM). It assumes an annual load curve and predicts a maximum system load. The present discussions have performed estimation on demand for consumer use air conditioners in a day in which a maximum summer load occurs in a reference year, estimation on load in a maximum load day in an estimated year, and estimation on weather sensitivity of loads. 5 refs., 5 figs.

    This report summarizes the fiscal 1999 research result on simulation analysis on petroleum substituting energy. The simulation model for analyzing social and energy supply and demand structures comprehensively was established by improving the China and Korea models developed in fiscal 1998 through a use of input-output tables. In simulation of the China model, the reference case showed that a primary energy demand in 2030 reaches 3.3 times as much as that in 1997 (2.9 times in CO{sub 2}), resulting in serious energy and environment problems. Reduction of primary energy and CO{sub 2} is possible by promotion of energy saving and introduction of a carbon tax. In simulation of the Korea model, the reference case showed that CO{sub 2} emission in 2030 reaches 2.2 times as much as that in 1997, showing an annual increase rate of 2.4%. The annual increase rate can be reduced by introducing a carbon tax. The simulation model for automobile energy was also established for major countries in Asia. Automobile energy consumption increases with diffusion of automobiles until 2030 gradually. In particular, the consumption in China reaches that in Japan in 2010. (NEDO)

    The purpose of this research is to identify the problems and measures for reduction of GHG emissions by conducting research on the GHG emission trends in the energy-conversion, industry, public and transportation sectors, and policies and regulations. Japan`s total emission of CO2 in FY 1994 was 343 million tons in terms of carbon, and the emission per capita was 2.74 tons. These amounts were 7% increase in total CO2 emissions and 6% increase in the emission per capita compared with those in FY 1990. There were high increases in the public and transportation sectors. This trend is expected to continue in the future. Since more than 90% of CO2 emission is derived from energy origin, the climate change problems mean energy and economic problems. To attain Japan`s goal of the year 2000 with maintaining the appropriate economic growth, it is crucial to accelerate energy-efficiency and introduction of new energy. 19 figs., 28 tabs.

    The effect of lemon, jasmine and lavender aroma on people was studied through environmental aroma experiments by 270 subjects in a meeting room for two months. As a result, the high percentage of positive responses was obtained on the sense of air cleanliness and efficiency of meetings, and a statistical significance was, in particular, obtained in the case of lemon as smoking was permitted. It was suggested that aroma had physiological and phychological effect even under conditions where the subjects were not necessarily aware of aroma. The effect of the same three aromas was also studied through experiments by 13 subjects in a VDT room for one month. As a result, the number of keypunch errors decreased in every aroma although punching speeds decreased slightly, and lemon showed a significant difference among three aromas.

    The solar car race which technical high school students can join in was determined to be held at Ogata village, Akita prefecture. To join in the solar bicycle race, the author working in Ofuna technical high school called on 3 schools of Yokosuka, Fujisawa and Kanagawa technical high schools which joined in World Solar-Car Rally in Akita (WSR) in 1997, before fabrication of a racing bicycle. This paper describes the survey results at the above technical high schools, and the spirit as the teacher of Ofuna technical high school on joining in the race and fabrication of the solar bicycle, and the past, current and future situations. Club activities of high school students incline too toward sports such as soccer, baseball, volleyball and rugby, and are apt to keep honest cultural events and technical events at a distance. The author says that the challenge spirit to the solar car race using environment-friendly solar energy by both dedicated teachers and students of technical high schools summoned up the author`s courage. 15 figs.

    The nacelle shape of a mimic engine mounted on the wind tunnel test model for an STOL aircraft developed by the National Aerospace Laboratory has much larger length than in the nacelle of a scale reduced to 8% of an actual engine, and the shape below the nacelle is different. Therefore, in order to estimate the air force in the actual aircraft from the aerodynamic data obtained in a wind tunnel test, the data are corrected by using differences in aerodynamic loads (estimated values) applied on the mimic engine and the actual engine. For the purpose of discussing the reasonability of this correction, an 8%-scale flow through nacelle with the same shape as in the actual aircraft (the actual aircraft type) and a flow through nacelle for a wind tunnel testing model of the experimental STOL aircraft were fabricated and wind tunnel tests were performed. These results were compared with the corrected results of the mimic engine wind tunnel test. As a result, it was made clear that the force data have been corrected excessively, and the moments have been corrected considerably well. 7 refs., 32 figs., 7 tabs.

    DBW (Drive By Wire) system makes the constraint of direct connection between an accelerator pedal and the throttle valve free, so that optionally turning of throttle valve sensitivity becomes possible in automobiles driving. Reported here is the discussion of the effect and the limitation of this optionally tuning. As the former result, it became clear that the tuning method using torque signal and speed signal of the drive shaft, was easier than the method using only speed signal by PD control action. And as the latter result, upper limit was bound by the low gear ratio and tire spin. 2 refs., 11 figs.

    This paper proposes a cone type electro-hydrodynamical (EHD) heat collector, describes its structure and principle, and mentions possibility of improving the heat collecting efficiency. The paper proposes a heat collector with a shape close to a cone. Trees are of cone form so that their every leaf, branch and truck can capture solar energy efficiently. Imitating this fact existing in the natural world, a cone-shaped heat collector was fabricated on a trial basis to discuss its heat collecting efficiency. Furthermore, black round stones are placed in the inner cone of the cone- shaped heat collector of double-glass structure. A low boiling point medium is placed between the inner and outer cones to cause corona discharge in vapor generated by absorbing the solar heat, and generate corona wind for an attempt to accelerate heat transfer into a heat exchanger. Thus, development was made on a cone-shaped high-efficiency heat collector utilizing electro-hydrodynamical (EHD) effect, and elucidation was given on dynamic phenomena of an electro-thermal fluid. Heat transfer in the EHD heat collector has a possibility of being accelerated by generation of ionic wind. In addition, it is thought that there would be an optimum value in applied voltage to increase electric charge supply as a result of corona discharge. 1 ref., 2 figs.

    Aggravation in electric power quality is concerned because of irregular output power caused by a large number of photovoltaic power generation systems connected with the power grids. However, averaging of the irregularity may be expected in a wide area due to time-based shift in cloud movements. In order to identify this effect, insolation data were measured in terms of planes at multiple points in the city of Tsukuba to discuss the fluctuation equalizing effect. The system is composed of nine instruments to measure insolation plane characteristics, nine terminal station units, and a base station unit. The insolation data express the horizontal plane insolation intensity at a sampling interval of one minute. Insolation fluctuation (standard deviation of insolation fluctuation components) was defined as an index of the insolation fluctuation. Based on the index, an averaging effect when the photovoltaic systems are installed in a number of locations was considered by using statistic estimation. As a result, the averaging effect was obtained even in an area with a radius of several kilometers. In addition, the measurement data revealed that there is an upper limit in the effect depending on the number of system installation. It was also made clear that the data are affected by distances to connect the photovoltaic power generation systems with each other and by climatic conditions. 3 refs., 6 figs.

    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.

    For the foundation improvement works by grouting in a borehole, evaluation of grouting effect is one of the most important management items. The grouting design and works are sometimes reconsidered depending on the evaluation of grouting effect during the test injection. The purpose of the evaluation of grouting effect is to grasp the range of improvement and consolidation after the injection, and to judge and estimate the strength and permeability of the consolidation part. This paper describes the judgment method of the strength using PS logging results and borehole televiewer (BHTV) logging results. The reflection intensity (Ir) by the BHTV logging increased after the grouting, which showed a same tendency as that using S-wave and P-wave velocities (Vs and Vp) before and after the grouting. This was considered to demonstrate the grouting effect. A relation was obtained between the Vs, Vp and Ir before and after the grouting, which was expressed by following equation. Ir=0.143{times}Vs-70=0.093{times}Vp-110. The relation with the dynamic elastic coefficient (Ed) was also obtained as follow; Ir=0.0013{times}Ed. 9 figs.

    This paper analyzes how much of the power demand could be reduced in the future by improving efficiencies of electric power utilizing appliances used in the residential and commercial sector. It discusses whether the reduction would lead to load leveling. Annual load rate in the power demand is continuing to decrease because of power demand increase in the residential and commercial sector, and increase in demand for air conditioning in summer. If a technology to improve electric appliance efficiency is proliferated to its maximum scope, the annual load rate in fiscal 2014 may be improved by 1.1 percent point. Since the improvement allows new power generation facility installation cost to be deferred, the power generation unit cost can be reduced by 0.11 yen per kwh. If a heat storage type air conditioning technology is proliferated to its maximum scope, the annual load rate in fiscal 2014 can be improved by 1.8 percent point, and the power generation cost may also be reduced. If the device efficiency improving technology and the heat storage type air conditioning technology are introduced to their maximum simultaneously, the annual load rate in fiscal 2014 can be improved by 2.5 percent point, and the power generation cost may also be reduced by 0.24 yen per kwh. If a promotion policy is taken on proliferation of a specific device efficiency improving technology having excellent economic performance by providing subsidy, the reduction amount of cumulative power generation expense will be much greater than the required subsidy amount. 10 refs., 9 figs., 22 tabs.

    In recently, comfortable life can be spent by performing complex of fibers. As complex of single fibers being materials of yarn, conjugate fiber is listed. Conjugate fiber is a fiber spun over 2 kind of polymer having different characteristics from one nozzle. There are sheath core type fibers as complex functional fibers. Static electricity prevention fibers can be prepared by putting conductive materials, for example, carbon black into core parts. After putting components being able to dissolve by specific solvents into core, hollow fibers can be prepared by dissolving core parts in near process to products. By reason of clothing contacting to skin directly in board aria and long time, fashionable characters of design and so on or comfortability of wearing are needed in many cases. In this reason, many kinds of fibers for clothing prepared complex yarn by being complex and by making the best use of good characteristics of each fibers, and developed a way to new function or new use.

    A new diesel combustion concept termed MULDIC (MULtiple stage Diesel Combustion), which can reduce NO{sub x} emissions at high load conditions, was studied by means of engine test, combustion observation and numerical simulation. The engine test showed that simultaneous reduction of NO{sub x} and smoke could be obtained with MULDIC operation. In-cylinder combustion observation was carried out in order to clarify the cause of the smoke reduction of the MULDIC. In these photographs, a first stage combustion sins observed with nonluminous flame. In a second stage combustion, a highly sooting luminous flame was observed because the ignition delay was short. However this luminous flame disappeared quickly. Computational results showed that, oxygen is distributed evenly in the cylinder in later portion of the second stage combustion. Moreover, since cylinder temperature was very high, most of the soot oxidized rapidly. Thus, low smoke combustion was obtained. (author)

    Inquiries are made to consumers (monitors) who own a photovoltaic power generation system at their houses, and their replies are analyzed for isolating the factors involving the purchase of this domestic power generating system. A large part of the monitors are 40-50 years old males in the relatively high income bracket. They are very interested in problems of global environments, resources, and energy, and are inclined to assume value-consciousness and life-style which encourage them to love health and nature, participation in social functions, and decision-making. The need for the protection of global environments occupies more than 90% of the reasons for their adoption of photovoltaic power generation. The monitors strongly feel, however, that they paid very much for the apparatus although they were granted some subsidies. As for motives for their acquisition of the system, their answers are categorized into four groups according to their responses as to whether (or not) they expect economic merits though dependent on future development and whether (or not) they accept the current energy policies. The result shows that some monitors think like average citizens. 17 refs., 22 figs., 11 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.

    The Great Hanshin-Awaji Earthquake caused great damage to roads. Not only on highways, but even in regional communities, a considerable number of streets became unusable because of falls of buildings, etc. to roads and occurrence of bumps. It provided obstacles in refuge and rescue activities. In building cities preparing for earthquake in future, it is important to re-evaluate how to make the road network including narrow streets. Therefore, paying attention to the physical distance of the roads in earthquake and the number of the points which people cannot reach, clarified was the relation between those phenomena and the characteristics of towns/roads which the region has. As an example of Higashinada-ward, Kobe-city, this report analyzed the data on the actual state from the aspects written below which become especially important in actions taken immediately after earthquake, and described the information/knowledge obtained therefrom: (1) difference in arrival distance between usually and in earthquake in case of walking from residence place to refuge place; (2) state of occurrence of the points where people cannot reach in going to hospitals by ambulance.

    In order to study coal production processes, an estimation study was carried out on coal originating materials by using biomaker analysis. Test samples are original coals collected directly from a mine in Hokkaido (not having been subjected cleaning). Mixing and solvent extraction were performed after pulverization, and then tests were given on saturated hydrocarbon components divided by using a silicagel column chromatograph for the present study. It can be known from n-alkane distribution in the coal that low molecular alkane increases with increasing degree of coalification. Artificial coal made by wet-heating Metasequoia leaves contains only little n-alkane. Diterpenoid compound exists in the Taiheiyo and Akabira coals. Tetra-cyclic diterpernoid is contained abundantly in subtropical coniferous trees, serving as a parameter for warm environment. The compound is contained also in the Fushun coal, but not in Indonesian coals. Hopanoid constitution shows very high similarity, but H/C atomic ratio may vary largely even if the coalification is at the same degree. This is likely to be caused from difference in originating materials. Hopanoids are bacteria attributed substances, whose activities are not affected by the originating materials. 2 figs., 1 tab.

    Electric utilities positively wrestle now with business diversification such as telecomunication, thermal supplying, urban planning to intensify the administrative foundation under relaxation for regulations. These businesses are yet small scale ones but are supposed to enlarge to the scale equivalent to the main business for a long period. Since the electric industry is a public utility enterprise and has fewer experiences to develop concrete diversifying strategy, this research was proceeded to determine the directions of diversification by analyzing management data or making hearing for well-diversified corporations such as fiber industry, private railway industry, and leasing industry. It was found from this study that diversification would have the possibility of plus for multiple managerial indeces such as profitability, growability and stability and that the diversification would be developed by using effectively the managerial resources. Then, the conditions on which electric utilities must consider when they enter into new businesses were arranged on the basis of this survey. 46 refs., 14 figs., 9 tabs.

    A simplified method is developed, which measures dioxins in flue gas without using GC/MS (gas chromatography/mass spectrometry) of the double focusing type. The sampling device is built of two collecting bottles, containing water and diethylene glycol, and uses no XAD-2 (cross-linked amberlight divinyl benzene) resin. Such a design does not need time consuming Soxlet extraction in the sampling process and shortens the processing time. An HPLC (high performance liquid chromatography) system replaces the convenient column chromatography system in the cleanup process, and this enables automation and rapid treatment. For the measurement of toxicity equivalent, GC/MS is used to separate and quantify 17 kinds of toxic isomers as in the conventional method. The GC/MS is of the quadruple focusing type, however, and this reduces the device cost at the initial stage and shortens the time for operators to acquire the skills of maintenance and operation. Though the quadruple focusing type is inferior to the double focusing type in sensitivity, the shortcoming is compensated for by massive specimen injection using a PTV (programmable temperature vaporizer). The result of a JIS (Japanese Industrial Standard) method and the result of this newly developed method are found to agree excellently with each other. This method is simple and efficient, suitable for use in the analysis of small incinerator flue gas. (NEDO)

    A method to inspect the rattle, one of the transient noises of car interior, is developed. In the method, the waveform data of overall noise are analyzed using Wigner distribution, and its rattle component is condensed and separated from the background excitation noise. Then the rattle component is classified into three levels: strong, middle and none, using the neural network. A fuzzy inference is also used to select regular waveform measurements. Experimental results show that the correct classification ratio of the method is more than 90%, which equals skilled inspection operators in accuracy. 11 refs., 8 figs.

In fiscal 1995, the following were conducted for enhancement of generalization of the method: expansion of environmental load items and increase in validity of the concept, and expansion of database. Notice was taken of not only CO2 but SOx, NOx and water quality load items. The survey was made on the recycling situation in Japan and abroad and the PET recycling plant , and environmental load item data are collected to expand database. The program was verified by analyzing an example of reusing PET bottle to carpet, and one-step development can be made toward the establishment of the method. Moreover, an analysis was made for the environmental assessment of the related programs abroad, and a tentative original plan can be proposed for the standardization of environmental load analysis and the integrated assessment method. 39 refs., 130 figs., 76 tabs.

    With economy growing at a fast pace in the Asia-Pacific region in recent years, demand for energy is sharply increasing in various industries, and the demand is expected to continue to grow. It is afraid that the trend may extend to other developing regions such as East Europe. It is, and will remain to be, important to prevent warming, assure sustained economic development, and secure stable supply of energy on the global scale. The survey in this report aims to grasp the trends of energy efficiency improvement in Asia-Pacific nations, in other developing nations, and in developed nations as well, to ultimately serve the best interests of Japan. For the achievement of the goal, Japan's attitude toward energy conservation promotion activities is expressed at international conferences on energy conservation promotion such as those of APEC (Asia-Pacific Economic Cooperation Conference) in the Asia-Pacific region and of environmental/energy-saving conferences of IEA (International Energy Agency) in Europe and America. On these occasions, information is collected and overseas technical literature is obtained thanks to the established coordination with United Nations-affiliated organizations and key persons in various countries. Data and information thus acquired are utilized for the investigation and analysis of energy conservation technologies and policies adopted and diffused in the respective nations involved. Using them, promotion of energy conservation policies in the Asia-Pacific region and establishment of environmental friendliness are also investigated. (NEDO)

    We have developed a systematic design task planning method based on a design structure matrix(DSM) and a lumped model- based framework for knowledge sharing in a concurrent design environment as key techniques for developing higher quality products in a shorter design time. The DSM facilitates systematic analysis of dependencies among design tasks and optimization of the design process. The framework based on a lumped model description of mechanical systems enables concurrent and cooperative work among multidisciplinary designers at an early stage of the design process. In this paper, we also discuss the relationships between these techniques and the product development flow from product definition to detailed design. (author)

    Study is under way for a more accurate solar radiation quantity prediction for the enhancement of solar energy utilization efficiency. Utilizing the technique of roughly estimating the day`s clearness index from forecast weather, the forecast weather (constituted of weather conditions such as `clear,` `cloudy,` etc., and adverbs or adjectives such as `afterward,` `temporary,` and `intermittent`) has been quantified relative to the clearness index. This index is named the `weather index` for the purpose of this article. The error high in rate in the weather index relates to cloudy days, which means a weather index falling in 0.2-0.5. It has also been found that there is a high correlation between the clearness index and the north-south wind direction component. A multiple regression analysis has been carried out, under the circumstances, for the estimation of clearness index from the maximum temperature and the north-south wind direction component. As compared with estimation of the clearness index on the basis only of the weather index, estimation using the weather index and maximum temperature achieves a 3% improvement throughout the year. It has also been learned that estimation by use of the weather index and north-south wind direction component enables a 2% improvement for summer and a 5% or higher improvement for winter. 2 refs., 6 figs., 4 tabs.

    Technological change is a major driving force for long-run economic growth. New theories on growth have stressed the importance of innovative and adaptive capacity of firms in order to fully reap the benefits of research and development (R and D) within the firms as well as those spilled-over from other firms and abroad. This report empirically investigates the relationship between R&D and productivity as well as that between productivity and industrial competitiveness for the G-5 countries (Japan, the US, (West) Germany, France and the UK). To do so, we have constructed comparable data on R and D capital stock (so-called 'knowledge capital'), the level and growth rates of total factor productivity (TFP), and the revealed comparative advantage (RCA) index for 22 manufacturing industries in each G-5 country. The major results are summarized as follows. First, the volume of knowledge capital for Japan is still far smaller than that of the US (40% for total manufacturing in 1995). Second, there is no clear tendency of TFP convergence to the US level for each country after 1980 and its level for Japan is about 70% of the US in 1993. In addition, the TFP gap between Japan and the US has recently widened for high-tech sector. Third, the estimated elasticities of TFP with respect to the R&D stock for manufacturing sector during the mid-1970s and the early 1990s are 0.07 for Japan and 0.21 for the US on average, with deteriorating R and D potency in Japanese manufacturing. For high-technology industries, they are much larger with the estimates of 0.45 for Japan and 0.86 for the US on average, whereas for Japan the R&D performance becomes worse during the last decade. Fourth, we found that international competitiveness in industries depends not only on TFP and exchange rate fluctuations, but also on various non-price factors such as product quality, marketing ability, and product market segmentation.

    A proposal is made on a method to analyze a slope disaster in detail from a viewpoint of ''where the disaster occurred'' (to analyze in a line pattern the apertures of a collapse and main scarps in a land slide). Methodological emphasis was placed on superimposing aerial photograph images taken before and after a disaster over imaged information on factors based on land conditions including topographical characteristics. Applicability of this method was discussed using a landslide location in Niigata Prefecture as an example. This paper describes the result of tb discussion by the following items: Imaging the aerial photographs and correcting their geometrical distortion; extracting items of line-pattern information from the aerial photographs and classifying the land coverage; and analyzing factors of causing the landslide using an image superimposing process. The papers also mentioned a view that this method may be applied effectively on disasters occurring on ground surface. 11 refs., 8 figs., 2 tabs.

    For development of production technologies suitable for environment, safety and advanced information-oriented society by improving the flexibility of production lines, some new measurement technologies were researched. Problem solution was attempted by combining the in-situ multi-dimensional measurement technology capable of easily obtaining various 3-D information with the non-contact photon measurement technology superior in operability and sensitivity under any environment conditions. This solution requires a compact radiation source with higher brightness and wider spectral range, and a high-sensitive detector. The technology concentrating photon onto minute regions, high-efficiency transmission, and control technology of photon wave front are also necessary. Development and international standardization of a common interface is unavoidable. In addition, its network is essential for advanced use of multimedia,. In the future, the comfortable life surrounded by advanced products and multimedia, comfortable social environment, safety and resource saving will be achieved by this technology. 94 refs., 75 figs., 15 tabs.

    The material balance of carbonization products (wood-gas, wood-vinegar, wood-tar and charcoal) prepared from the sapwood and the heartwood of Sugi (Cryptomeria japonica D. Don) at various temperatures was determined. The evolution of both carbon monoxide and carbon dioxide mainly occurred at the carbonization temperature below 600 degree C and that of hydrogen and methane at 600-800 degree C. Total yield of the wood-vinegar and the wood-tar was almost constant at 500-800 degree C. On the other hand, the yield of the charcoal decreased because of the evolution of the wood gas with an increase in carbonization temperature. The wood-vinegars prepared at the temperature over 400 degree C were found to consist of carboxylic acids such as acetic acid and propionic acid, methanol, acetone, furans, alkylphenols, guaiacols, cyclotene and maltol by capillary gas chromatography. Since the constituent varieties and contents of the wood-vinegars prepared at both 400 degree C and 800 degree C were very similar each other, the wood-vinegar of Sugi wood chiefly produced below 400 degree C. FT-IR spectra of the charcoals showed the generation of carbonyl and olefin groups at 300-400 degree C and then the formation of aromatic rings along with the disappearance of carbonyl groups over 600 degree C. The production of radical species in the charcoals carbonized at 300-600 degree C was observed by ESR, on the contrary, the charcoals carbonized over 700 degree C were inactive. The specific surface area and the pore volume of the charcoal of Sugi sapwood increased with an increase in carbonization temperature. The pH of charcoal-dispersed aqueous solution increased with an increase in carbonization temperature. The high adsorptive activity of the charcoal carbonized at 400 degree C for ammonia gas and that at 800 degree C for hydrogen sulfide gas seemed to be dependent on acidic and basic properties of the charcoals, respectively.

In the previous, although there was a measuring method of mental stress by RSA, a issue arise such as reliability of analysis, because driver`s heart rate affect by respiration and muscle motion as well. We have established a method to measure mental stress by fractal dimension. And tried it is the proving ground and public road driving. We have confident that it is more reliable than RSA to quantify driver`s mental stress and fatigue. 9 refs., 9 figs., 1 tab.

    Looking for effective policy on petroleum substituting energy, measuring models were made for analyzing relations between changes in social structure and energy supply/demand structure. Through the simulation using these models, effects of difference in energy policy on economy and energy supply/demand were studied. Countries for survey were Thailand, the Philippines, Indonesia, Malaysia, China and Korea. The measuring model is composed of the macroeconomic model and the energy supply/demand model. In the case of Korea, the interindustry-relations model was added. Using the macroeconomic model, asked were fluctuations in various economic activities/industrial structure/price/trade balance such as GDP and crude steel production by inputting overseas indices, population indices and financial indices such as the world trade, crude oil price and exchange rates. In FY 2000, for ASEAN countries, data were collected for analysis of relations between changes in economical/social structure and energy supply/demand structure. Using the pilot model constructed, the simulation was made on the standard case. (NEDO)

    In relation to coal gasification and combustion under high pressure as highly efficient coal utilization, the effect of total pressure and sintering on the SO2 capture ability of Ca-ion exchanged coal and other desulfurizing agents were studied. In experiment, specimens were filled into a small pressurized reactor to heat them under high-pressure N2 atmosphere. After the completion of combustion reaction of char at 850{degree}C, SO2, CO2 and CO gases were measured at an outlet while flowing SO2/N2. As the experimental result, all of the S content in Ca-ion exchanged coal was not absorbed by Ca content in coal during pyrolysis and combustion, resulting in discharge of 36% of the S content. Since Ca-ion exchanged coal is fast in combustion reaction, most of the S content was desulfurized by coal ash. The ash content yielded from Ca-ion exchanged coal was more excellent in SO2 capture ability than limestone even under higher pressure. In the case of CO2 partial pressure lower than equilibrium CO2 pressure for CaCO3 decomposition, the capture ability decreased with an increase in total pressure, while in higher CO2 partial pressure, it was improved. 1 ref., 7 figs., 2 tabs.

    Catalytic effects of metal and carbon materials, which promote hydrogen transfer from hydrogen donor solvents, are investigated during hydrogenolysis of benzyl-1-methylnaphthalenes (BMN) selected as a hydrogen acceptor. For the isomer distribution of BMN after the reaction, almost the same molecular ratio before the reaction was obtained independent of the presence of catalysts. Selectivity of position during the addition of hydrogen atoms from tetralin was not found. For the reaction of BMN in tetralin, 1-methylnaphthalene and toluene were obtained as products, but the formation of benzylnaphthalene was not found. As for the nuclear hydride of BMN, the trace amount formation was confirmed by gas chromatography. For the hydrogen transfer from tetralin progressed catalytically, it was found that the nuclear of naphthalene can not be hydrogenated easily. This was considered to be due to the obstruction of hydrogen transfer from tetralin by the strong adsorption of BMN on the Ni surface. 1 ref., 1 fig., 2 tabs.

    The developmental trend of the reduction technology of greenhouse effect gas emission from automobiles was surveyed. Development of low pollution, energy saving and substituting energy vehicles such as electric, methanol and natural gas vehicles is in rapid progress together with performance improvement of conventional gasoline vehicles. For example, since GDI engine directly injects fuel into cylinders, it can control an air/fuel ratio at will, and reduce CO2 emission. Lean burn engine vehicle and hybrid vehicle are also under development. Performance improvement of storage batteries for electric vehicles, in particular, that combined with solar cells, and the practicability of hybrid vehicles are being clarified. Among them, the superiority of fuel cell technology in the future is becoming clear from a general viewpoint, because of its high efficiency and no CO2 emission. As methanol is produced from plants, construction of cyclic energy systems is promising. However, since low emission vehicles are expensive, some policies such as legal obligation and subsidy system are important. 30 refs., 95 figs., 26 tabs.

    Single atomic layer epitaxy (ALE) aims at controlling a growing film at a precision of single molecular layer. In this article, it is reported that the growth temperature range of ALE was expanded by the vertical irradiation of KrF exima laser (248 nm) onto the substrate for the ALE growth of GaAs using the metalorganic chemical vapor deposition (MOCVD) method. Thanks for the results of the above experiment, it was demonstrated that the irradiation effect was not thermal, but photochemical. In addition, this article studies the possibility of adsorption layer irradiation and surface irradiation as the photo-irradiation mechanism, and points out that coexistence of both irradiation mechanisms can be considered and, in case of exima laser, strong possibility of direct irradiation of the adsorption layer because of its high power density. Hereinafter, by using both optical growth ALE and thermal growth ALE jointly, the degree of freedom of combination of hetero ALE increases and its application to various material systems becomes possible. 16 refs., 6 figs.

    Investigations were given on nanocrystals of CuCl and CdTe with regard to their nonlinear optical mechanism. The experiment used a femto-second pump probe spectroscope. The experiment on CuCl nanocrystals revealed the following facts: in the case where one photon is absorbed into one nanocrystal, cascade mitigation occurs to the pair of electrons and holes, and exciters; and in the case where two photons are absorbed into one nanocrystal, exciter molecules are made via the pair of electrons and holes and the exciters. Thus, it was found that the optical nonlinearity occurs when more than two photons are absorbed into one nanocrystal, and inter-exciter interactions and formation of the exciter molecules are the physical causes thereof. The experiment on CdTe nanocrystals indicated that electrons and holes produced by laser beam are distributed instantaneously between the size-quantized discrete levels, and that temperature in the electron system drops with lapse of time. 9 refs., 6 figs.

    For waste water treatment facilities of S marine products industrial complex, a demonstrative test was carried out on a waste water treatment method in which addition of biological activity promoter `quillaia saponin` and the aerobic/anaerobic method are combined. In the S marine products industrial complex, there are more than 100 plants which deal mostly with salt-preserved and boiled-fish-paste products. The plant is operated by the activated sludge method with the pretreatment pressurized floatation. The capacity of the aeration tank and concentration tank for the experiment was 2600m{sup 3} and 110m{sup 3}, respectively. The amount of saponin added was approximately 3mg/L for the amount of influent (raw waste water). The measurement items were transparency, SS, COD, BOD, n-hexane extracts (oil content), MLSS, etc. As a result of the experiment, it was found that the equipment of flocculant addition and pressurized floatation as pretreatment facilities is not necessary; the activated sludge treatment of even the waste water in which n-hexane extracts are more than 100mg/L is possible without the pretreatment; and the n-hexane extracts in the treated water is less than 2mg/L. 7 refs., 7 figs., 6 tabs.

    For the waste water from meat processing factories, high in BOD and fat concentration, an effective treatment method was studied, wherein quillaia saponin was dosed. The waste water treatment facility of Factory K, manufacturer of ham and sausage, includes a total volume of 410m{sup 3} of aeration tanks taking in an average of 300m{sup 3}/day of waste water. The facility suffers from sludge overflows routinely, and, as a measure to cope with the situation, coagulating agents are dosed to the waste water for forced settlement. Under these circumstances, investigations were conducted to learn the effect of saponin dosing to the facility. Beginning on the 50th day of operation, saponin was dosed to the aeration tanks, and no coagulating agents were dosed to the waste water being treated by aeration. Approximately 3mg/liter of saponin was dosed to the influent waste water not treated. As the result, it was found that the BOD value decreased in the treated waste water while that in the influent untreated waste water increased as the run advanced. Even when the load grew heavier and the pretreatment was dispensed with, there was improvement in the treated water thanks to saponin dosing, which confirmed the effectiveness of saponin dosing. 6 refs., 11 figs., 3 tabs.

    A technique is discovered for improving on the baking properties of cerium oxide which is one of the solid electrolytic materials for SOFC (solid oxide fuel cell). Cerium oxide, samarium oxide, and gallium oxide are weighed, each to the specified element ratio. The element ratio of cerium is fixed at 0.8 against the other elements except oxygen, and the element ratios of samarium or gallium are caused to change. Specimens containing gallium are designated as CSGa, those not containing as SDC. SDC baked at 1600degC and CSGa (1%) baked at 1450degC are similar to each other in terms of average grain diameter. Specimens with gallium added thereto can be baked at temperatures that are lower than these by approximately 150degC. The conductivity of CSGa (0.2%) baked at 1500degC is higher than that of SDC baked at the same temperature, and is similar to that of SDC baked at 1600degC. Baking is enhanced by the addition of 0.2% gallium. In the domain where more than 1% of gallium is in presence, conductivity lowers with an increase in the amount of gallium added. The conductivity of CSGa (1%) baked at 1450degC is similar to that of SDC baked at 1600degC. 4 figs., 1 tab.

    This article introduces the electron beam curing (EBC), which is high speed non-heating cure technique for the high performance resin for structures, conducted by Aerospacial Co., Ltd. In this technique, very strong electron beam and X-ray are used in response to the thickness of curing region of members, and the muzzle has energy of 10 MeV as permeation control energy and power of 20 kW as cure time control power. Advantages of fabrication of composite products by EBC is derived from the elimination of exoergic and heating curing processes and the local cure molding. For the EBC, the residual stress is not generated, the size is stable, the insertion of different materials is easy without mismatch of thermal expansion between the composites and metals, the homogeneous bridge can be obtained to stabilize the material quality, the processing time can be shortened, it is suitable to mass production, and the cure of products can be controlled. About 30% to 40% of the cost of products can be reduced. 1 ref., 6 figs., 1 tab.

    A quasi-crystalline Al65Cu20Fe15 powder prepared from alloy cast rapidly solidified by metal-mold casting, and then it was mixed to aluminum powder with various volume fractions by mechanical milling. The powder milled for above 50ks made homogeneous dispersion of quasi-crystalline phase with particle size less than 1{mu}m. The powder was hot-pressed under various conditions and then its features of consolidation were examined by the observation of microstructure and fracture strength in 3-point-bending of the compacts. When the milled powder was hot-pressed at higher compacting temperature than 673K for 3.6ks under pressure of 600MPa, the compact became to dense. Hardness of the obtained compact increases and its fracture strength decreases with increasing volume fraction of quasi-crystalline particles. Intermetallic compound Al7Cu2Fe forms in the interface of aluminum matrix and quasi-crystalline particle. 11 refs., 10 figs.

    Tyre/road interface noise can be amplified by a horn type space formed by the tread face of the tyre and the road. This paper is a report on studies on experiment and computation to elucidate the above phenomenon in detail. Measurement and computation were carried out on a tyre replaced with a single cylinder, whereas it was verified that the horn effect by each frequency can be calculated by BEM computation. Then, discussions were given on actual tyres combined with the BEM computation, and the following results were acquired: (1) the horn effect is small in zones of low frequencies; (2) the larger the tread width, the larger the horn effect increases; (3) the relationship between the tread width and the horn effect is governed by the ratio of the road contact width to noise wavelength; (4) the frequency characteristics of the horn effect vary largely according to whether the sound source exists in forward or rearward locations; (5) the relationship between the forward and rearward locations of the sound source with the horn effect is governed by the distance between the front and rear ends of the road contact face of the tyre; (6) the smaller the radius of the tread shoulder, the greater the horn effect; (7) tread deformation due to load applied on the tyre slightly changes the frequency characteristics of the horn effect; (8) with the sound source existing closer to the center of ground contacting width, the horn effect increases; and (9) the present study has verified the horn effect of 22 dB as the maximum. If the sound source is not present at the center of ground contacting width, the horn effect is reduced to about 10 dB, but the value cannot be ignored as the influence on traffic noise.

    The effect of tack coat on bonding characteristics at the interface between surface and base layers was studied for airport asphalt pavement. In a fracture behavior, shear stress is first caused by horizontal loading at the interface between surface and base layers, resulting in peeling of the layers in the case of poor bonding. Further loading under the above condition results in fracture of asphalt concrete layers by bending or tensile actions. The bonding strength between layers decreases with an increase in interval of construction between surface and base layers, while the bonding strength between layers increases with sufficient curing of tack coat. Curing for 1 hour in the daytime and 6 hours or more in the nighttime is sufficient for evaporation of water content in asphalt emulsion. The use of conventional asphalt emulsion for the sandy interface as tack coat deduces the bonding strength in the case of poor curing. Asphalt emulsion containing high-penetration rubber can improve the bonding strength. 12 refs., 27 figs., 2 tabs.

    An investigational study was conducted aiming at making a quantitative grasp of effects of the spread of industrial heat pumps on energy conservation and greenhouse gas reduction and at promoting the spread. Finally, the following eight countries joined this international joint research: Canada, France, Japan, Holland, Norway, Sweden, the U.K. and the U.S. Each country share the work and expenses for the research with each other. Japan made investigational researches on the application of heat pumps to processes of the chemical industry, oil refining industry, food industry, paper/pulp industry, and dyeing/weaving industry, and on the effects of greenhouse gas reduction. As procedures taken, values up to 2010 were estimated of energy prices in each country, energy supply/demand, rates of the heat source configuration for electric power supply, etc., the heat flow of the above-mentioned process was made clear, and analyses were conducted of annual profits, energy consumption, and depreciation period in the case of adopting heat pumps. Moreover, the energy conservation amount and greenhouse effect gas reduction amount were estimated based on the result of the analyses. 69 figs., 196 tabs.

    Temperature and humidity characteristics and condensation within walls under heating and humidification were studied experimentally in winter using two test houses of conventional and ventilated structures. The absolute humidity in conventional one fluctuated depending on temperature gradient, water flux due to humidification and water adsorption onto glass wool, and accumulated water increased with humidification. That in ventilated one was also affected by dehumidification through ventilation layers. Under heating and humidification, the absolute humidity increased depending on temperature rise and water flux within walls. In conventional one, condensation was frequently observed on felt in walls and others because of accumulated humidity, while in ventilated one, humidity was kept lower within walls even under heating, because humidity in walls was discharged through ventilation layers. Condensation was also scarcely observed on waterproof moisture-permeable sheets in walls and others. 3 refs ., 39 figs 1., tab.

    The effect of synthetic plant hormone 4-C1-IAA and TFIBA on root growth in plantlet propagation was clarified by the cuttage and the issue culture of strawberry seedling production. A periwinkle, vine, and azalea are the effect of 4-C1-IAA on root growth, and a promotion effect was recognized for rooting and root elongation. The concentration of 4-C1-IAA in which the growth promotion effect of a root most appears varies depending on the species of a plant. The concentration of a periwinkle was 20 ppm, and that of an azalea was 2000 ppm. The growth promotion effect of a root in 4-C1-IAA and TFIBA was compared with IBA for an azalea. The result showed that 4-C1-IAA is the same in the effect as IBA and that TFIBA is higher than for IBA. The growth of a vine`s terminal bud was promoted by the effect of TFIBA on root growth, and the callus occurring when IBA was treated was not formed. The rooting of a strawberry was promoted by the effect of TFIBA on root growth. The combined use of TFIBA and BA promotes the growth of a side bud and forms a multi-bud plant. However, rooting was inhibited. The callus caused by the effect of BA on root growth could be suppressed through the combined use with TFIBA. 6 refs., 7 figs., 2 tabs.

    It was intended to confirm, based on various problems surrounding oil flow-out accidents, that oil fences whose use is first considered when an oil flow-out accident occurs cause oil leakage due to oil pass-through phenomenon as the largest defect in performance of oil fences. Therefore, oil fence performance was analyzed by using a simulation. Furthermore, several types of diffusion prevention and avoidance measures, and combinations thereof were evaluated by using multi-criteria analysis. It was also elucidated how recognitions on the importance of methods to prevent oil pollution differ depending on standpoints. Difference in oil flow-out prevention performance of oil fences due to variation in tidal currents was made clear by combining a diffusion simulation using the finite element method with the prevention performance of oil fences relative to the tidal currents. In areas with no good hydrographic conditions where pollution spreads rapidly, it is necessary to suppress oil diffusion by extending oil fences double or triple, and using gelling agents. 4 refs., 8 figs.

    For ground water exploration using vertical Schlumberger exploration method, measurement and analysis combined with induced polarization (IP) effect were conducted as trial. For the Schlumberger method, potential is measured at the center between potential electrodes during flow of dc current between current electrodes. In the case of vertical exploration, measurements are repeated with fixed potential electrodes by extending the distance between current electrodes. Ground water exploration was conducted using this method at Otaki village, Hokkaido. Geology of surveyed plateau consists of a basement of Pliocene tuffs and Quaternary Pleistocene sediments covering on the surface. For the results of analysis, four to seven beds were detected from the resistivity. The depth up to the lowest bed was between 25 and 85 m, the resistivity of each bed was between 9 and 8,000 ohm{times}m, and the polarizability was between 1 and 15 mV/V. Among these resistivity zones, it was judged that zones satisfying following three conditions correspond to coarse grain sediments saturated with ground water, and can be expected as aquifers; having resistivity ranging between 100 and 1,000 ohm{times}m, polarizability higher than 10 mV/V, and relatively large thickness. 11 refs., 6 figs.

    The effect of activated carbon (AC) on biodegradation of organic micropollutants in water was investigated, using fenitrothion, phenol and aniline as the model compounds, activated sludges cultured in a mixed solution of glucose, peptone and aniline, and Rhodotorula glutinis isolated as the phenol-degradation bacterium. The following conclusions are obtained by analyzing the corrected degradation curves derived from the adsorption equilibrium relationships, oxygen consumption characteristics and observed degradation curves. Biodegradation of each compound is accelerated in the presence of AC. Non-biological degradation of fenitrothion is also accelerated in the presence of AC, its effect being more noted in biodegradation and increasing as AC quantity increases. Phenol is biodegraded by different mechanisms, depending on its initial concentration. The maximum oxygen consumption rate during the biodegradation of phenol increases in the presence of AC, conceivably resulting from enhanced bacterial activities. 5 refs., 6 figs., 4 tabs.

    The purpose of this study was to investigate a traffic environment that can reduce traffic accidents of elder walker. We focused on the relationship between traffic accidents and elder person`s spatial attention. In this paper, an adolescent subject`s and an elder subject`s pointing movement to a visual target was measured in three conditions. Condition 1: Only target was presented. Condition 2: Auditory stimulation was added at a location the same distance from the center as that of the targets but in the opposite direction. Condition 3: Auditory stimulation was added at the same location as the target. The targets were placed in extra working space with the distance of 1.5 meter from a subject to the targets. In adolescent subjects, results showed that in Condition 3, latency was shorter and the error rate of pointing movements was lower than in the other conditions. In elder subjects, results showed that in all Conditions, ignore ratio to peripheral targets is higher than adolescent subjects. Nevertheless, in condition 3, ignore ratio was lower than in the other conditions. These results suggest that, it is possible to draw elder walker`s spatial attention and to control spatial attention by auditory stimulation. 13 refs., 6 figs., 1 tab.

    The generation mechanism of the vertical vortices associated with the baroclinic instability and the effects of nonlinear term on the vortices are investigated by using both direct numerical simulation (DNS) and rapid distortion theory (RDT). Two kinds of the anisotropic flow fields are used as initial conditions. As a result, the initial anisotropy of Reynolds stresses is found to affect asymmetry of the vertical vortices. In the cases where the initial vertical velocity is set to be zero, the p. d. f. of the vertical vorticity tends to incline toward the anticyclonic side. When the vertical component of initial velocity is larger than the horizontal one, the cyclonic vortices are more enhanced. By comparing DNS and RDT, it is found that in both cases of the initial conditions the enhanced vortices of DNS are stretched in the vertical direction, which is not observed in the RDT results. This should be because the nonlinear vortex-stretching term intensifies and elongates vertical vortices in the vertical direction. The anticyclones are markedly augmented in low Prandtl number fluids, while the cyclones become dominant in the high Prandtl number case. In particular, the flow field becomes almost two-dimensionalized and Taylor columns are formed in the vertical direction in the low Prandtl number case. However, neither two-dimensionalization nor Taylor column is observed in the RDT analysis which neglects the nonlinear terms. (author)

    The composite panel with photovoltaic-thermo module becomes higher in energy-saving than the conventional air-conditioning system by the independent radiational heating and cooling effect obtained when the generating panel using a solar cell module is combined with the heating and cooling panel using a thermo-element module. The output of a solar cell module can be directly used because the solar cell module operates in AC. This paper reports the relation between the absorbed value and power consumption of the cooling panel, while paying attention to the cooling panel. The performance coefficient of the maximum absorbed value from an non-absorbing substance to a cooling panel is 2 to 3. Assume that the cooling panel during non-adiabatic operation is operated using a solar cell module of 800 W/m{sup 2} in solar intensity and 15% in conversion efficiency. The cooling-surface temperature difference is 12.12 K, and the maximum absorbed value of a non-absorbing substance to a cooling panel is 39.12 W/m{sup 2}. The absorbed value of the outer temperature to the cooling panel is 74.4 W/m{sup 2}, and each performance coefficient is 3.26 and 0.62. The absorbed value must be calculated for evaluation from the cooling-surface temperature difference measured directly from the cooling panel. 4 refs., 8 figs., 1 tab.

    Burning rate and specific impulse of a solid propellant are extremely important parameters in a design of a solid rocket motor. In this study, the relations between the burning rate and the amount of energy contained in HMX-CMDB propellants wherein the amount of energy is varied by adding HMX (High Melting Point Explosive). The following results are obtained. The final flame temperature is getting higher when the amount of energy is increased by adding HMX into a double-base propellant. The higher the final flame temperature is, the lower the burning rate is. Dark zone temperature, as a physical property, is lowered when the containing amount of energy is increased by adding HMX into the double-base propellant. This is because that, when weight fraction of HMX is increased, reaction heat at burning surface decreases, and the reaction in fizz zone is getting slower. The higher the dark zone temperature is, the higher the burning rate is. 20 refs., 11 figs., 1 tab.

    Effects of 4WD and ABS on safe driving were examined by brake, obstacle avoidance, acceleration, cornering and lane-changing tests on slippery road. The braking operations, used in these tests, are full, intermitted and modulated brakings. As the results of discussion, the major findings are (1) ABS is effective to shorten the stopping distance and to increase the ability of obstacle avoidance in many cases, (2) `Modulated Braking (without wheel locks)` has the same function as ABS, and (3) 4WD is effective to increase the stability while accelerating, cornering and lane-changing. 5 refs., 6 figs.

    Through an arrangement of published data about American air lines during 1985 through 1987, the overall expense vs. transportation fee (expense vs. effect) was studied as a main viewpoint. As a result, the fuel oil cost, even in case of wide fuselage plane, high in transportation efficiency, was high in ratio, 32 to 52% (3 to 5 times as high as that 12 to 14 years ago), and fluctuated connectedly with the oil price. While the jet fuel price fluctuated connectedly with the oil price per equal volume with 1.3 to 1.4 of price ratio. Further, the flight range ratio was recorded to be approx. 0.06 to 0.24 km/kg. While the transportation efficiency was lower than approx. 5000kg*km/kg with a wide range of overall expense, approx. 9 to 87 cents per compensative transportation ton*km. Because even a sudden decrease in transportation quantity did not decrease the overall expense, it was known to be important in management to secure the transportation quantity. 30 refs., 15 figs., 1 tab.

    In recent years, the techniques for the typical PC bridges shown in the title have been considerably developed in Japan. However, occurrence of characteristic vibrations of the parallel cables even at relatively low wind speeds are observed in many cases, for which an effective control means is inevitably required. In this report, an investigation of tests on effectiveness of 4 kinds of vibration control means carried out in a wind tunnel and its results are described. In the test, an elastic model of 3-dimension was used for 5 test cases including a case without any control means, and each case was explained and examined in detail. It was revealed that for a damping system, a considerably large damping effect was necessary to restraint the wake galloping, and the cable distance selected to be 1.5 times smaller or 6 times larger than the cable diameter was effective, and while vibration control wires were effective, the adjustment of the cable vibration frequency was ineffective. It was also pointed out that a further verification would be necessary for the latter 2 control systems as no enough experience was yet accumulated in the actual service. 13 refs., 16 figs., 6 tabs.

    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.

    The Brunei Project is a joint venture among the Brunei Government, Shell and Mitsubishi Shoji, but when its supply began in 1972, the share ownership has consisted of Mitsubishi Shoji and Shell at 45% respectively and the Brunei Government at 10%. The mutual reliance relationship among the project partners has been built gradually in such ways as Shell has built an agricultural vocational school inviting professors specialized in agriculture from England. Mitsubishi has created a large-scale cattle breeding business and produced beef cattles under the severe tropical environment, with an unfortunate result that the production cost did not balance with the market price. Recently, three Japanese agricultural engineers have succeeded at last producing tomatoes, cucumbers and lettuces through endeavors of vegetable production by means of hydroponic processes. The Brunei Goverment is also planning to cultivate fish and shells. Meanwhile the voices from the working site stress strongly that the operation has been continued with the safety-first concept at all times.

Since conventional analysis technique using an energy-fixed X-ray excitation source is inadequate to obtain satisfactory surface sensitivity and quantitative accuracy for catalysts, for development of the titled technique, this project makes experiment using energy-variable synchrotron radiation to modify the parameter on motion of low-speed electrons in solids which is obtained by Monte Carlo calculation. For establishment of the high-accuracy quantitative analysis technique of surface compositions of materials such as catalyst of which performance is dominated by utmost surface, the project studies the attenuation length of electrons in solids by electron spectroscopy using soft X-rays from synchrotron radiation. In this fiscal year, the project established the equipment and technique for high-accuracy quantitative analysis of the thickness and electron attenuation length of silicon oxide films on silicon wafers by electron spectroscopy.

    This project targets to make analysis of surface chemical phenomena of solid catalysts possible, and establish the basis of intelligent design for catalytic materials, through development of an advanced electron spectroscopy for surface analysis. In fiscal 1999, the research was promoted by using the diffraction grating and driving mechanism introduced in fiscal 1998, and by developing the measurement result on silicon oxide films by radiation beam photoelectron spectroscopy. The measurement technique was established by the optimized measurement process which can treat variable parameters as constant. The analysis result of measurement data in fiscal 1999 showed the dependence of an electron damping length in silicon oxide films on radiation photon energy. The energy dependence well agreed with a theoretically obtained inelastic mean free path of electrons qualitatively, while was smaller by nearly 30% than the latter quantitatively. Measurement was made on the damping length in oxidation-active Gd and Nd oxide films. In both cases of Si and Si oxide film substrates, oxidation of substrates or formation of silicate was observed.

    The survey on the reduction measures against greenhouse effect gases was carried out which was proposed by the IEA-GHG phase 3 program. In Japan, various low emission vehicles (LEV) such as electric, methanol and natural gas vehicles are under rapid development. Like France, cost reduction and preparation of fuel filling stations are urgently necessary for the diffusion of LEVs. In New Zealand, air pollution by automobiles is not essential. The Switzerland government is promoting the diffusion of compact electric vehicles, and inhibits the use of conventional automobiles in some tourist resorts. The California state is leading the world by prescribing the bold regulation for preventing the air from pollution. In particular, the state government put automobile manufacturers under an obligation to produce zero emission vehicles (ZEV, electric vehicle) by 2% of passenger cars and trucks from 1998 and to increase ZEVs up to 10% until 2010. This report also includes two papers concerned, `Forestry management for sustainable development` and `Tropical forestry action plan after five years.` 142 refs., 19 figs., 23 tabs.

    Product evaluation has been investigated from a viewpoint of compatibility with human life by considering human being as the subject of life. This report describes the investigation results. Product evaluation is defined as evaluating products on a consumer-oriented viewpoint and informing consumers of the evaluation results. According to a questionnaire survey with regard to daily living products, products in the low degree of satisfaction in their usage were electric tooth brush, video camera, electric rice jar, vacuum cleaner, and electric iron. Contents of dissatisfaction with these products were classified by aspect, i.e., human aspect regarding human body/recognition, life aspect regarding functions of products and how to use them, and sensitivity aspect such as appearance of products. Thus, points at issue were clarified. As regards the human aspect, incompatibility between the size/form of products and human body/posture, and recognition psychological incompatibility such as difficulty in understanding function or operation of products were pointed out. Establishment of a method for measuring and evaluating the human`s body functions and the compatibility with products, and necessity of the acquisition of human`s body characteristic data and the consolidation positions are also described. 4 refs., 42 figs., 30 tabs.

In Chapter 1, energy supply and demand in the above-named four countries is reviewed on the basis of recent economic situations in these countries. In Chapter 2, bilateral inter-industry relations tables usable under the project are employed for the analysis of the economic status of each of the countries and energy transactions between them, and a method is described of converting the tables into one-nation inter-industry relations tables which meet the need of this project. In Chapter 3, national characteristics reflected on the respective energy input tables are described, and a method is shown of converting a nationally characterized unit energy table into a common unit energy input table for registration with a database. In Chapter 4, the constitution of the Asian energy consumption efficiency improvement analyzing tool and a system using the tool are explained. In Chapter 5, some examples of analyses conducted by use of the analyzing tool are shown, in which the energy saving effect and CO2 emission reduction effect are estimated for Indonesia by use of the analyzing tool.

    This study is done for the purpose of numerically analyzing how customers react to make their choice between quality and price, as well as to evaluating the marketability of the new electric service differentiated by quality, on the assumption that electric utility is capable of providing the multi-product of the service with various combinations instead of the conventional single product between price and quality. An analysis was made for the customers like the large-scale computer users those who attach importance to quality. As for the method of the analysis, the choice (the introduction of emergency power source or uninterruptible power system) which have been actually done by the customers for the following two conditions, were used as the model of the analysis: The one was the standard of the requirements for the quality of electric power, of which requirements were composed of the two factors, such as the reliability on power supply and momentary voltage drop; The other was the cost (purchased power price plus investment by consumers for back-up power system) necessary to maintain the quality. Consequently, it was found that in order to heighten the competitiveness for the competition in electricity market, electric utility had to establish their service rate corresponding to the load, as well as that the quality was a important strategic factor for them. 30 refs., 10 figs., 9 tabs.

    An objective evaluation from a third party was conducted on the purpose, plan, execution method, achievement, etc. of a project 'The devilment of the catalyst surface high accuracy quantitative analysis technology using electron spectroscopy.' The purpose of the project is to make the relationing possible between the analytical results of the catalyst surface and the catalyst performance which has been so far difficult by heightening the accuracy of the catalyst quantitative surface analytical accuracy using the electron spectroscopy. The purpose and significance are judged to be worth a lot. This project is an industry/university/government joint project between the two countries. The project is excellent both in connection among research institutes and leadership of chief researchers, and it is judged that the joint research system fully functioned. The term of the project was shortened from 3 years in the first plan to 2 years, and therefore, the study was finished only on silicon oxide and organic thin films. However, it was determined that the study results are to be run in the magazine 'Surface and Interface Analysis,' which indicates that the achievement was judged to be very worth in the academic viewpoint.

    A d.c. bias current driven by the self-bias voltage which is conducted through the r.f.-powered glow discharge plasma varies the emission characteristics drastically, leading to improvement of the detection power in the optical emission spectrometry. By conducting the bias currents of 20-30 mA, the emission intensities of the atomic resonance lines were 10-20 times larger than those obtained with conventional r.t.- powered plasmas. The detection limits for determination of alloyed elements in the re-based binary alloy samples were estimated to be l.6 x 10{sup -3}% Cr for CrI 425.43nm, 7 x 10{sup -4}% Mn for MnI 403.10nm, 1.9>10{sup -3}% Cu for CuI 327.40nm, 1.1 x 10{sup -3}% Al for AlI 396.16nm, and 6.6 x 10{sup -3}% Ni for NiI 352.45 nm.

    This paper describes comprehensive evaluation and analysis mainly on the 51 items adopted in the high-performance industrial furnace introduction field tests. The development of a high-performance industrial furnace has completed the fundamental development research in fiscal 1998, and the possibility was verified on energy saving of more than 30% and reduction of NOx emission by 50% over that by conventional furnaces. Upon this fundamental achievement, the field test project has started as the comprehensive approach to developing the practically usable technologies for three years from fiscal 1998 until fiscal 2000, which is being promoted as a joint research project. According to the survey on the actual state in fiscal 1998, a little less than 20,000 industrial furnaces having combustion capacity of more than 500,000 Kcal/hr (excepting boilers) are being used. If these furnaces are converted into the high-performance industrial furnace, energy conservation of 210,000 x 10{sup 6} Mcal (converted to crude oil of 22.7 x 10{sup 6} kl/year) can be achieved from the maximum annual energy consumption of 700,000 x 10{sup 6} Mcal (converted to crude oil of 75.7 x 10{sup 6} kl/year). This conservation amount corresponds to about 12% of the final energy consumption in the whole Japanese industrial departments in fiscal 1996. It is expected that the performance of the full-size high-performance industrial furnace will be verified, and this technology will be promoted for wide proliferation. (NEDO)

    The project aims to prepare inter-industry relations tables and models for energy analysis for Asian countries and thereby to probe into relations between the industrial structure or the ultimate consumption structure and energy consumption. For the comprehension of energy consumption as broken by each industry, Asian nations' inter-industry relations tables and energy statistics are linked for the compilation of energy analysis oriented inter-industry relations tables, and the resultant tables are used for the metric analysis of industrial structures and energy consumption structures in these countries. The tables prepared this time are 1985 tables for Korea, Indonesia, Thailand, and the Philippines and 1990 tables for China, Singapore, and Malaysia. The Malaysian transportation sector needs to be improved in energy saving. In Singapore, energy saving is functioning effectively in the transportation sector. China's energy consuming industries are those involving coal, chemistry, steelmaking, ceramics, and earth and quarrying. In Taiwan, improvement needs to be made in the transportation sector. Korea should conserve energy in the transportation sector. In the Philippines, energy needs to be saved in businesses related to water supply, transportation, and fishery. Thai industries as a whole needs to save energy. Improved energy consumption efficiency is sought for in the Indonesian cement related sector. (NEDO)

    Carbon emissions which would cause global warming were agreed to be constrained at COP3 in Kyoto. In addition, carton emission permits trading was also approved to be introduced. The emission permits trading is expected to achieve efficient carbon emission reduction, equalizing the marginal costs of the emission reduction for the participating countries. In other words, the permits trading allows participants to reduce emissions where it is least expensive to do so. However, the inadequate introduction of the trading systems may impose unfairly greater burden on some countries, and therefore careful evaluation of the system would be indispensable for its implementation. In this paper, we attempt to analyze the emission permits trading. using the theory of cooperative games with a global energy model of optimization type. We assumed that seven world regions as players participate the permits trading system under the condition of the emission reduction target presented at COP3 and so on, and show the nucleolus of the grand coalition games, and the computational results of primary energy supplies and CO2 shadow prices. The insights of this research indicate that in order to stabilize the grand coalition, a noticeable amount of additional transfer of money would be needed besides the payments associated with the emission permits trading. 10 refs., 7 figs., 5 tabs.

    Materials related to IEA Greenhouse Gas Rand D Program (IEA/GHG) were analyzed. The Sleipner carbon dioxide underground storage workshop is acting to narrow themes for understanding the technologies, observation methods, and research activities. The IEA/GHG has verified the known facts about ocean storage of carbon dioxide, and discussed the important development targets. Researches were made on improving methane recovery efficiency and the possibility of sealing carbon dioxide by injecting carbon dioxide in order to improve recovery of carbon bed methane. The IEA/GHG has developed a methodology for complete fuel cycles of LNG, and evaluated cost and benefit of reducing greenhouse effect gas emission. A process combining electric power generation, carbon dioxide absorption and hot heat energy utilization can reduce emission of carbon dioxide into atmosphere at relatively low cost and low energy loss. The paper also describes reduction of greenhouse effect gas emitted from cement factories, petroleum refining and petro-chemical industries, and offshore petroleum and gas facilities. It also describes influence of forestry on carbon absorption and timber markets. Case studies have discussed effects of modifying power generation plants. (NEDO)

    Comparative investigation of numerical analysis results of out-of-plane secondary stress caused in a cross beam web around scallop before reinforcement and around cutting portion of vertical stiffeners after reinforcement was carried out. In case of steel truss bridge, there exists difference in axial thrust between outside stringers which continue through a cross beam, and it was revealed that this axial thrust was the main factor which causes partial bending stress in a cross beam web plate. When the lower end of vertical stiffeners is not connected to a cross beam foot flange considering of welding, out-of-plane secondary stress was caused partially in a cross beam web plate around scallop, because of the difficult to transmit adjoining stringers axial thrust difference directly to foot flange. In case of the actual analysis, cross beam web plate around cutting portion of vertical stiffeners causes partial out-of-plane secondary stress in web plate, due to being pressed partially by comparatively high stiffness vertical stiffeners. When repair and reinforcement of steel road truss bridge are carried out, it is necessary to take close attention specially on the structure of the parts in which outside stringers is connected to cross beam. 18 refs., 16 figs.

    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.

    This paper summarizes the basic materials related to unified evaluation models for global warming. The unified evaluation is a disciplinary process to combine, interpret and share the information from different scientific disciplinary areas in such a form that the whole cause and effect chain can be evaluated from a macroscopic view. The process has higher utilization value than the evaluation overemphasizing a single academic area, and can provide decision makers with useful information. The process is suitable to model complex interactions and feedback mechanisms in diversified scenes such as climate change. The unified evaluation can identify the policy criteria along with a measure framework having consistency. The evaluation process is repetitive and continuous, wherein a science community can convey comprehensive knowledge and finding to a decision making community. In turn, the decision making side can feed back the experiences and achievements in learning. Execution of the evaluation requires different approaches, such as judgement of specialists including the modeling methods and experience, discovery as a result of applying the policies, and survey methods. The paper also describes the gaming conception, scenario analysis, and unification evaluation methods. (NEDO)

    Effective use of the limited natural resources and preservation of global environments are sought for with the 21st century approaching. In the field of measurement analysis, 21st century type technologies are desired, different from the current ones whose improvement is to be attained through reaching for the limits of sensitivity and resolution. Although the laser device with its performance innovatively advanced has now come to provide light sources for measurement, yet they retain their own flaws of damaging or destroying the object of measurement. Passive measurement techniques need to be developed using natural light or white light as well as laser, which will enable the measurement of the shapes and characteristics of human beings, other animals, and vegetables by use of their radiation, and to determine the kinds and amounts of components of the living environments by use of natural light. Techniques should be developed to measure, in natural light or artificial illumination, shapes and colors, and microscopic substances on solid matters, their temperatures, and reaction processes in factories and laboratories. In this connection, surveys are conducted of technologies for measuring safety, productivity, and environment improving potential. Technologies key to their realization are those involving novel heterodyne interference and light source quality improvement, light amplification, cohering, signal processing, chemistry and mass transfer, establishment of multidimensionality, systematization, etc. (NEDO)

    Local heat transfer and pressure drop measurements were made during condensation of CFC 11 in microfin tubes. A smooth tube and two microfin tubes with different fin dimensions were used. Flow observation study with use of an industrial bore-scope revealed that the condensate swirled along the grooves, and a thick condensate film covered fins in the lower part of the tube in the low quality region. Static pressure gradients in the microfin tubes were up to 70 percent larger than that in a smooth tube. A correlation equation for the local frictional pressure gradient was derived, in which the effect of refrigerant mass velocity was introduced on the basis of the flow regime consideration. The measured frictional pressure gradient data were found by the present method to have a mean absolute deviation of 8.3 percent. 24 refs., 11 figs., 3 tabs.

    Process solvent was hydrogenated in the brown coal liquefaction, to investigate the influence of it on the prethermal treatment and liquefaction. Consequently, it was found that the n-hexane soluble (HS) yield was improved. In this study, capacity of hydrogen transfer from solvent during prethermal treatment and effects of catalyst were investigated. Since prethermal treatment in oil was effective for improving the oil yield in the presence of hydrogen/catalyst or high hydrogen-donor solvent, influence of hydrogen-donor performance of solvent or addition of catalyst on the hydrogenation behavior of coal and the characteristics of products during prethermal treatment were investigated in relation to successive liquefaction results. As a result, it was found that the increase of HS yield was due to the acceleration of conversion of THF-insoluble using high hydrogen-donor solvent and/or by adding catalyst. It was also found that the use of high hydrogen-donor solvent and highly active catalyst at the stage of prethermal treatment before the successive liquefaction was effective for improving the HS yield, i.e., liquefied oil yield. 2 refs., 5 figs., 1 tab.

    Three kinds of coals with different rank of 76, 85 and 87C% were hydrocracked to study the specific reaction behavior of four kinds of 1coal liquefaction catalysts such as CuCrO4, Fe2O3+S, MoO3-TiO2 and MoS3-Al2O3. The reaction was conducted without any solvent to find out the specific phenomenon of each combination of coal and catalyst, and terminated at the point where nearly 30% of an initial amount of coal is converted to benzene-soluble. The products were separated by GPC into four fractions, and their average molecular weights and intrinsic viscosities were measured to study characteristics of each combination. As a result, the molecular weight distribution was obviously dependent on the combination of coal and catalyst, and no specific relation was observed between the molecular weight and intrinsic viscosity. The molecular of each fraction had a bar shape with an elliptic section indicating no apparent correlation with the molecular weight. 3 refs., 1 figs., 2 tabs.

    This paper shows the impact of the irradiation from an additional light source during the deposition of hydrogenated amorphous silicon by photo-CVD deposition. Using a mercury sensitized photo-CVD process from Disilan (Si {sub 2} H {sub 6}) and hydrogen, silicon was deposited. A 40W low pressure mercury lamp was applied as the light source. A portion of the substrate was in addition irradiated using an Xg-He lamp through a thermal filter. Irradiation of the substrate using only Xg-He lamp produced no deposition, since this light has a wavelength which is too long to produce the SiH {sub 3}-radicals needed for Si deposition. The additional Xg-He light source was discovered to cause an increased thickness of deposited a-Si:H film and a transmission of the band structure. The reasons of these are considered that the influence of irradiation is not limited to film thickness, but that irradiation also impacts the composition of the a-Si:H film so as to cause a reduction in the hydrogen content. 10 figs., 1 tab.

    The feasibility study was conducted on a project in Myanmar for the energy saving effect and reduction of the greenhouse gas emissions by introducing modern refining facilities in Thanlyin Refinery of Myanmar Petrochemical Enterprise. The project items selected as a result of the study are improvement in the heat recovery efficiency of crude distillation unit, improvement in the furnace efficiency of crude distillation unit and coker plant, improvement in the efficiency of power plant, reduction of steam loss, modernization of the cooling water system, recovery and reuse of off-gas and LPG in crude distillation unit, and modernization of intermediate products run-down system. The conceptual designs and studies on these items indicate that implementation of these projects could lead to energy saving of 25,844 tons/y as crude and CO2 emission abatement of 57,457 tons/y, 46% and 33% reduction from the baseline. The total expenses for all of these items are estimated at 4,300 million yen. These are judged to be promising projects, with estimated investment recovery period of 9 years and internal profit rate of 12.9%, when the special yen loans are available. (NEDO)

    As to intelligent transport systems (ITS), the paper views the outline of the R and D and diffusion in Europe, the U.S. and Japan and trially estimated the effect of reduction in greenhouse gas, and worked out visions/scenario for diffusion of ITS. As developmental fields contributing to reduction in greenhouse gas, the following were taken up: 1) AVCS (advanced vehicle control system), 2) automatic rates receiving system, 3) traffic management, 4) plans of operation management/allocation of commercial cars, 5) modal shift of the material flow, and 6) public traffic in passenger transportation. As effects by developmental field, 1) and 5) are especially effective. 4) is promising because of its easiness in introduction, and 2) is also a promising technology as a tool to introduce an electronic road pricing system on general roads in future in addition to the effect of reducing heavy traffic by its introduction to expressways. However, the higher the service level on the facility side becomes, the more the traffic demand amount becomes. By how to introduce ITS, it possibly occurs that improvement of the situation will not be made at all on the future vehicle traffic system. 38 refs., 42 figs., 52 tabs.

    A proposal was made to introduce a photovoltaic/solar/air-heat system which positively utilizes natural energy in order to curtail consumption of fossil energy, corroborating that the system has greatly reduced energy input in the primary energy level in a house. This paper examines the effect of curtailment of energy input in the case of reducing the load of air conditioning through the high heat insulation of a house. The energy input was evaluated by calculating additional equipment energy needed newly for the high heat insulation. The system performance and the energy load varied greatly depending on weather conditions. The subject system consisted of solar cells, inverter, heat concentrator, heat storage tank, heat pump and gas hot-water supply device. The thickening of the insulation sharply reduced heating load in the house, thereby decreasing fuel energy substantially. An insulation material of 100mm thick was capable of reducing energy input by 16-23% compared with that of 50mm thick. 5 refs., 5 figs, 3 tabs.

    Although introduction of Joint Implementation (JI) and Clean Development Mechanism (CDM) have been adopted in the COP3, the details of how to set up the baseline for calculating the emission reduction amounts have not been established. This survey/research project has sorted out various concept menus for setting the baseline, verify each menu, and positively propose the methodology in an international arena, in which merits and demerits involved in simplified approaches, which try to simplify the works for setting the baseline, are analyzed, and their effectiveness is investigated. At the same time, both FCCC AIJ and NEDO AIJ projects are analyzed, to understand characteristics of baseline-setting method adopted by each project. There are many project types, to which direct application of any simplified approach is difficult. It is therefore realistic to analyze the situations case by case for the time being, and pursue for possibility of standardization of the baseline-setting methods after sufficient experience and data are accumulated to allow classification of the projects by common features.

    The reactivity of oxygen methylated coal was studied to control hydrogen bond in bituminous coal liquefaction and intermolecular cohesion such as van der Waals force. In experiment, crushed and dried Illinois coal of 100mesh or less was used as specimen, and oxygen methylated coal was prepared by Liotta`s method using tetrabutylammonium halide. Coal liquefaction was conducted in an electromagnetic agitation autoclave using tetralin solvent under initial hydrogen pressure of 100kg/cm{sup 2} while heating. The molecular weight distribution of the products obtained was measured by gel permeation chromatography (GPC) analysis. The experimental results are as follows. The effect of intermolecular cohesion in bituminous coal on the reactivity is mainly derived from decomposing reaction from preasphaltene to oil. Yields of oil fraction by methylation increase corresponding to release of intermolecular cohesion. Since the thermal release is promoted with temperature rise, the difference in yield due to different treatments decreases. 5 refs., 3 figs., 1 tab.

    In the present paper, an attempt is made to develop an effective EHD enhancement technique for condensation heat transfer of steam around a horizontal finned tube. The main idea in the present study is to reduce the power consumption by using a partially coated electrode, and the experimental data of heat transfer coefficients and flooding angles are presented. The result indicates that, by using such an electrode, the enhancement ratio keeps almost the same level with that of a bare electrode but the power consumption can be markedly decreased. Within the present experimental range, the condensation heat transfer coefficient on the finned tube with the partially coated electrode reaches a value about 3 times larger than that without electrode. In addition, a model in presented for the EHD effect on the flooding angle and it is confirmed that the prediction from the model is in good agreement with the experimental data. (author)

    In this study, taking the all factors involved in the energy consumption in residential houses as subjects, the effectiveness of the solar PV system and solar thermal utilizing system in residential houses has been studied by simulating a model residential house considering the improvement of the residual environment in the future. Therefore, a model residual house is assumed, 18 kinds of combinations of construction style, cooling and heating type and solar energy utilizing form are assumed and year round simulation is carried out. The conclusions obtained by the simulation are as follows. The energy consumption in residential houses may decrease greatly by using a solar hot water supplying system. If combined with a solar PV system, the energy consumption in one year is about 8.7 to 9.7 MWh. The combined use of a solar thermal utilizing system and a PV system is more effective to reduce the second-time energy in comparison with the PV system only. 36% of the space heating energy consumption may be decreased by using the solar space heating system, but the decrease effect of the energy consumption of the solar space heating system is smaller than the solar hot water supplying system. 12 refs., 26 figs., 3 tabs.

    A model house was simulated to reduce the consumption and peak demand for the photovoltaic power generation system, and solar heat air heating and hot water supply system in the solar house. As a type of construction, both wooden construction and reinforced concrete (RC) construction were selected with a total floor area of 125m{sup 2}. All the rooms were equipped with an air conditioner by heat pump from the air thermal source. A solar heat floor heater was simultaneously installed on the first floor. The hot water supply load was 4.8MWh per year. A commercial grid-connected on-site system was applied to the photovoltaic power generation with a 20m{sup 2} wide monocrystalline Si solar cell panel. As for the fluctuation in power load, the peak at the time of rising is more reduced in the RC house than in the wooden house, because the former is smaller in temperature fluctuation than the latter during the intermittence of air conditioning (as per the specified operational schedule). Therefore, the power is more leveled off in the former than in the latter. Between both, difference was hardly made in energy consumption per year. The ratio of dependency was 47% upon the photovoltaic power generation system, while it was 50% and 77%, under the air heating power load and hot water supply power load, respectively, upon the solar heat air heating and hot water supply system, so that both systems were considerably effective in saving the energy. 5 refs., 7 figs., 1 tab.

    Introduction effect of load levelling system by a battery in an electric power system by a battery in an electric power system with a PV and wind system is investigated. Charge and discharge power of the battery are determined from a load curve and every hour data of PV and wind output. Annual cost of the power system is calculated from the generating power and the capacity of each source via the installed utility capacity and the capacity factor. It is found that (1) the battery system reduces the maximum demand and improves the load factor, (2) the cost effect of the battery system when introducing the PV system is higher than that when introducing the wind system.

    Antimutagenic effect of humic substances has been reported by various investigators. In this research, the diminishing effect of DNA damaging toxicity by humic acid was evaluated for the influent and effluent of activated sludge tank receiving municipal wastewater and several DNA damaging chemicals (e.g., pyrene, 1-aminopyrene and benzo(a)pyrene) using Bacillus subtilis rec-assay. The diminishing effect was not apparent for influent but observed in the effluent. Among the DNA damaging chemicals, the DNA toxicity was effectively suppressed by humic acid for pyrene and benzo(a)pyrene. However, the effect was relatively smaller for 1-aminopyrene. 19 refs., 6 figs., 6 tabs.

    This paper describes the fundamental surveys in fiscal 1999 on cases and effects in relation with development of new energy technologies. Among the projects having been performed by NEDO in commemoration of the 20th anniversary of the NEDO foundation, the economic and social situations in the times in which the projects have been carried out with the focus placed particularly on new energies were put into order and analyzed to make clear the positioning of the project significance in the nation's energy policies. In addition, the roles of NEDO were recognized afresh to use them as the fundamental materials to serve for the future policy development. For the past thirty years before and after the oil crises, the time division that can be used universally for the project evaluation was established, based on the trends inside and outside the country, social currents, related indexes, and the status of development execution. Work hypotheses were presented regarding the basic conception in the evaluation, specific evaluation viewpoints, and their contents. Based on the hypotheses, three subjects were taken up as representative cases, that is, photovoltaic power generation, coal liquefaction, and phosphoric acid type fuel cell technology development. Time points that are considered as the important turning points were specified to give evaluations at respective turning points. Analyses were also made on decision making factors for project planning, continuation, direction change, suspension, and completion. (NEDO)

    A survey is conducted into the effects of projects implemented under the large-scale industrial technology research and development system. In the development of 'ultraperformance computers,' each of the technologies is being widely utilized, and the data service system of Nippon Telegraph and Telephone Public Corporation and the large computer (HITAC8800) owe much for their success to the fruits of the development endeavor. In the development of the 'desulfurization technology,' the fruits are in use by Tokyo Electric Power Co., Inc., and Chubu Electric Power Co., Inc., incorporated into their desulfurization systems. Although there is no practical plant based on the 'great-depth remotely controlled submarine oil drilling rig,' yet oceanic technologies and control methods are being utilized in various fields. The 'seawater desalination and by-product utilization' technologies have enabled the establishment of technologies of the top level in the world thanks to the resultant manufacture of concrete evaporator and related technologies. Eleven plants have been completed utilizing the fruits of the development. In the field of 'electric vehicle,' there is no commercialization in progress due to problems in cost effectiveness though remarkable improvement has been achieved in terms of performance. Technologies about weight reduction, semiconductor devices, battery parts and components, etc., are being utilized in many fields. (NEDO)

    A solar hot water system can be economically operated if inexpensive midnight power is purchased to cover the shortage of solar energy predicted for the following day. Investigations were conducted because error in insolation prediction affects the system operation and electric charge reduction effect. The target temperature of the heat accumulation tank at every predetermined time point is calculated on the previous evening in consideration of predicted insolation so that the water will be as hot as prescribed at the feeding time on the following day. Midnight power is used for uniform heating to attain the target temperature for 7 o`clock on the following morning. The uniform heating continues from 8 o`clock to the feeding time, this time using solar energy and daytime power to attain the target temperature. Accordingly, the division between the midnight power and daytime power is determined in view of the target temperature for 7 o`clock on the following morning, which target temperature is so set that the charge will be the minimum by optimizing the allocation of the above-said two. When the insolation prediction error rate is beyond 30%, the electric charge grows higher as the rate rises. But, when the rate is not higher than 30%, the charge is little affected by a rise in the rate. 5 refs., 10 figs., 1 tab.

    The thermal performance of direct gain passive solar houses was measured. Mr. M`s two-storied RC residence with double glazing windows and thermal storage floors, walls and ceilings of brick or concrete was provided for measurement. Its double eaves of the south window and both SE and SW overhanging exterior walls play a role in sunshade. Mr. I`s two-storied wooden residence with thermal storage RC floors and brick walls, and no eaves of the south window and no overhanging exterior walls was also provided. The summer and winter measurement results were in complete contrast between the residences. In summer, large thermal mass and eaves of Mr. M`s residence were effective, while in winter, small thermal mass and no eaves of Mr. I`s residence were effective. The following ideas are important in design from the viewpoint of indoor thermal environment: a movable sunshade for taking in solar radiation as much as possible in winter, well-balanced arrangement of thermal storage parts with suitable thermal mass corresponding to movement of the sun, a large screen door for cross ventilation in summer, and a night insulation shutter for reducing heat loss in winter. 2 refs., 10 figs., 1 tab.

    Answers collected from interviews show that very few of the bus passengers know how to open emergency exits and that such exits are floored too high, and dangerous, for aged people and children. In this paper, the emergency exit display is picturized in conformity with the ISO6309-provided evacuation signs, and the Chinese characters on the sign are replaced by `hiragana` characters for the youngest of the elementary school children, unable to Chinese characters, to read with ease. The cover is removed from the lever for opening the emergency exit so that the lever may be seen from the outside. Under the system now in use, the passenger reading the how-to-open explanation cannot see the lever, and therefore it takes some time to know how to open. Exit-indicating arrows are provided on the aisle. Now, almost all the subject passengers can evacuate themselves, including senior citizens and schoolchildren. Using this emergency exit indication method generally judged to be easy to use, the time length has been shortened from the beginning of evacuation to the arrival at the emergency exit. 5 refs., 8 figs.

    In order to improve the color stability of a coal derived light oil, the effect of hydrotreating and various additives has been studied. The color stability has been evaluated through measuring changes in absorbance by flow-cell spectrophotometer. Following results have been obtained: The color stabilities of hydrotreated coal derived light oils were improved remarkably with increasing hydrotreating temperature and pressure. Mild hydrotreating made the color stability of the coal derived light oil much better than the fuel oil, even though the nitrogen removal was very small. Phenolic compounds additives could not improve the color stability of the coal derived light oil. Alcohol, especially methanol, made the coloration rate of the coal derived light oil small to a great extent, on account of hydrogen bonding between methanol and nitrogen compounds in the fuel oil. 4 refs., 4 figs., 3 tabs.

    Described herein are the FY 2000 results of the survey on policies for reducing the greenhouse gas emissions. For Japan to meet the emission reduction targets stated in the Kyoto Protocol, it is necessary to examine in detail what the most desirable policy measures should be for each sector. In this context, it is also essential to determine particular features of the various policies that may include action plans, environment taxes, and emission trading in addition to conventional regulations and subsidy measures, and to assess their anticipated effects and problems. After examining the policies adopted by various countries to reduce greenhouse gas emissions, this study has attempted to identify the merits and demerits of the various emission reduction policies and to present a systematic account of progress achieved in Japan during basic investigations into this issue. This reports provides a systematic overview of the action plans adopted by the other major countries to prevent global warming and makes a comparative study of the contents of the policies that have been introduced by these countries; identifies the arguments raised in the overseas debates on the effects and problems of global warming prevention policies, and attempts to put the arguments into some systematic order; examines the statuses of the current progress made by various countries with regard to methane and N{sub 2}O emission reduction policies, and discusses the related problems; gives a systematic account of how the policy options are being scrutinized by the government as the base for studying the policy mix for Japan; and examines statuses of the current progress made by Japan with regard to methane and N{sub 2}O emission reduction policies.

    In the Asian region, for the purpose of grasping effects of both economic growth and effective energy consumption, an analytical tool added with a computational function was developed with the interindustrial relations table as database for the analysis of the present situation and the simulational analysis. In the analysis of the present situation, changes between the two time-points, 1985 and 1990, were analyzed using the developed energy consumption table and the CO2 emission table. The energy consumption amount is increasing with the growing economy. However, the energy unit consumption is decreasing in countries except Korea, the Philippines, Singapore and Malaysia. The trend is that the energy consumption is becoming effective and the CO2 emission amount is decreasing. As an example of simulating the introduction effect of energy saving technology, the simulation was conducted on the three: iron steel, paper/pulp, and cement in Indonesia. As a result, the decrease in energy consumption was shown in paper/pulp by 48%, in cement by 16%, and in iron/steel by 16%. The same was also indicated in CO2 emission. (NEDO)

    This paper reports the survey on hot water in the geothermal development promotion survey in fiscal 1999 in the Tsujinodake area. The hot water pumped up at the N11-TD-2 well is considered to have been originated from sea water mixed with the same amount of meteoric water including waters from Ikeda Lake and Unagi Pond, and been heated mainly by heat conduction. The hot water temperature near the well is 120 to 130 degrees C, but the upper stream of hot water flow is estimated to be 160 to 230 degrees C. The test samples collected and analyzed are those pumped up from depths greater than 1,500 m, having the same origin as the high temperature hot water of higher than 200 degrees C flowing sideways at the relatively shallow portions (depths of 400 to 800 m). The hot water is estimated to be rising from deep portions of mainly the north-east shore of Unagi Pond in which exhalation bands are located, and its temperature is considered to be 260 to 270 degrees C at deep sections. The high temperature geothermal reservoir spreading in relatively shallow sections of the N11-TD-2 well mainly around the vicinity of the north-east shore of Unagi Pond has a high possibility of being continued even to the vicinity of the west Ibusuki area in the north-east direction. However, the spread of the geothermal reservoir with high temperatures (200 degrees C or higher) is considered not too large in the direction of the Matsugakubo in the north-west and the Narikawa area direction in the south-east.

    Attention is focused on the molten carbonate fuel cell (MCFC) technology which has enjoyed the largest number of industrial property applications out of hydrogen-related technologies under development by NEDO (New Energy and Industrial Technology Development Organization). The patent application is utilized as a tool for analysis, and endeavors are made to systematize and then analyze the correlations between the tasks to discharge and the results of studies in the process of MCFC development. Findings are described below. It is quite difficult to specify the technology involved by the study of patent abstracts. Since an applicant for patent is inclined to describe the application so that it will cover an extensive scope (or, so that the patent will be taken in a broad sense), it takes much time for researchers other than the applicant to specify the field of technological studies where the application originates. Such being the case, it cannot be easily determined whether or not a patent applied for by a private-sector corporation has its origin in a NEDO-implemented project. In addition, it is found that there is not necessarily a correlationship between the importance of a research and development goal and the number of patents generated. (NEDO)

    Molibdophosphoric acid (PMo) reacts with malachite green (MG{sup +}) to form a colored ion associate (MG{sup +}- PMo) in an acidic solution according to the formula : HMG{sup 2+}+H{sub 3}PMo{sub 12}O{sub 40}{yields}(MG{sup +})H{sub 2}PMo{sub 12}O{sub 40}+2H{sup +}. A protonated form HMG{sup 2+} is yellow (the absorption mximum at 446 nm), whereas the ion associate MG{sup +} is blue green (the absorption maximum at 650 nm). MG{sup +} is found to accelerate the formation of PMo. Water-miscible organic solvents such as methanol,ethanol and propanol also accelerate the formation of PMo as well as the formation of MG sup + - PMo. Some anionic surfactants decelerate the reaction, however, contribute to the suppression of the baseline drift in a flow injection analysis (FIA). By the use of the proposed reaction accelerator and surfactant. a highly sensitive FIA system is established for,orthophosphate up to the range of several ppb. 16 figs.. 11 refs.

    Element technology is studied to realize a reflective-type, full-color, and high-resolution liquid crystal display for super-low power consumption data display. As to the functional compound microstructure formation technology, a 4-inch panel was trially fabricated using two-layer guest-host liquid crystal technology to achieve the desired display performance by control of molecular orientation. Further, holographic PDLC elements were favorably test-fabricated. A ferroelectric PZT thin layer was formed by forming layer at low temperature at which a glass substrate can be used. Optical interference/optical dispersion type optical control materials were studied by liquid crystal/polymer composition. Also studied were super-pure/super-reliable liquid crystal compound/liquid crystal composite systems and super-anisotropic liquid crystal compound by modeling ionic impurities and liquid crystal molecular interaction. In relation to the control technology of optical reflection characteristics, effects of liquid crystal molecular structures (derivative effect and copolymer composition) on orientation were elucidated. As to the technology to form multi-dimensional anisotropic structures, efforts were made for the heightening of formation technology of simple RGB (red, green, blue) directional reflection layers using acrylate materials.

    The paper studied the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. Chemical composition and coating thickness (g/m{sup 2}) of 14 kinds of specimens including alloy coatings and organic coating with zinc and aluminum as base were analyzed by the above-mentioned methods to examine the relation between the both. As the chemical analysis method, used was inductively coupled plasma atomic emission spectrometry. To study the relation between the methods, it was found to be necessary to recognize morphology at the boundary between the coating and base steel using, for example, scanning electron microscope (SEM) and electro-probe micro-analysis (EPMA). To measure traceability of the analysis method, with the chemical analysis method as a judgement method, it is necessary to make reference materials by coating materials, to use the calibration graph confirmed by the materials and to adopt the glow discharge optical emission spectrometry. On the basis of such way of thinking, drafts were worked out for the international standardization of the chemical analysis method and glow discharge optical emission spectrometry. 7 refs., 117 figs., 33 tabs.

    As an energy conservation promotion measure, a project is under development for introducing and subsidizing high-efficiency energy systems and for letting their effect known publicly and widely. The number of proposed energy systems has increased greatly and technical divisions to follow in classifying them have become vague, from which problems are now arising over the execution of follow-up checks and the maintenance of fair treatment. In the effort to solve this problem, 376 propositions are analyzed and classified, a technical classification method is proposed, and an instruction manual on the method is compiled. The classification involves (1) proposed classification, (2) variation, (3) energy reduction rate, and (4) tentatively calculated cost. Item (1) deals with the basic classification (air-conditioning, ventilation, and hot water supply, and, to be considered in combination with them, options which are cooking, illumination, and others) and, item (2) covers eight items such as new/old construction, structure, and structural frame. In Chapter 1 of the report, the 376 propositions are put in order according to common classification items and an original classification table is prepared. In Chapter 2, the goals are clarified and the classification principles are defined. In Chapter 3, the classification is checked for its validity and some realistic ways of grouping are described. In Chapter 4, a classification implementation flow chart is shown. (NEDO)

    A feasibility study is conducted aiming to reduce greenhouse gas emissions by refurbishing obsolete power stations in Shymkent City, the Republic of Kazakhstan. The clean development mechanism is also discussed. Aircraft engine-derived 20MW-class gas turbine cogenerators will be introduced, one each into a 1st and 2nd power stations. A simple-cycle model of the same will also be introduced into the 1st power station. The facility costs will be US$61.279 million for the 1st power station and US$33.590 million for the 2nd power station. The amount of fuel to be saved will be 238.6-thousand tons/year in terms of oil, totalling 5,964-thousand tons in a 25-year period. As for the reduction of greenhouse gas emissions, there will be a 737.9-thousand tons/year reduction in terms of CO2, meaning a total reduction of 18.448-thousand ton in a 25-year period. An FIRRROI (Financial Internal Rate of Return on Investment) is tentatively calculated using power and heat prices presented by the other party. The result of calculation shows that the net cash flow before and after tax stays negative throughout the whole operating period, which means a total lack of cost effectiveness. This is attributed to the low power and heat unit prices set by the other party, extremely lower than the internationally accepted prices. The FIRRROI after tax will turn positive when the unit prices are 1.5 times higher and the total investment is reduced by 20%. (NEDO)

    QoS control method which satisfies utilities communication network requirement and alternative route establishment method which is for sustaining communication during a failure are studied. Applicability of DiffServ (Differentiated Service), one of the most promising QoS control method on IP network and studying energetically in IETF WG, is studied and it is found most application used in the utility communication network except for relaying system information could he accommodated to the DiffServ network. An example of the napping of the utility communication applications to the DiffServ PHB (Per Hop Behavior) is shown in this paper. Regarding to the alternative route, usual IP routing protocol cannot establish alternative route which doesn't have common links and nodes in their paths for a destination. IP address duplication with some modification of routing protocol enables such alternative route establishment. MPLS, distance vector algorithm and link state algorithm are evaluated qualitatively, and as a result, we found MPLS is promising way to establish the route. Quantitative evaluation will be future work. (author)

    Emissions trading of greenhouse gases is going to be introduced to give flexibility to the method of achieving reduction of the greenhouse gas emission established in the Kyoto Protocol. The emissions trading is an institution intended to achieve the environmental targets by using the 'market mechanism' in the environmental policies, which is expected to accomplish the effect of reducing greenhouse gas emission. The U.S.A. has adopted since 1990 the policy utilizing the emissions trading on SO2 and NOx, creating cases of successfully achieving the initial regulation targets in a short time. The history of this SO2 emissions trading showed that the emissions trading that makes the market mechanism to function can function as a policy even in the environmental policy. The representative of business enterprises working actively on this issue is BP Amco. BP Amco has started January 2000 full-fledged greenhouse gas right-to-emit institution inside the company. Among electric power companies, Ontario Power of Canada has executed about ten greenhouse gas emissions tradings yearly. Enron International has structured a system in order to participate positively in the greenhouse gas trading. (NEDO)

    An examination was conducted concerning the course of spread of distributed power generation (on-site power generation of 2,000 kW or less) by the year 2010, with three scenarios prepared. In the scenario 1, the government will completely deregulates the power market and take no other steps, leaving the matter to market competition. The universal service will be abandoned, which means higher power prices for remote regions, contributing to the spread of home power generation. In the scenario 2, the government, having reached the limits of the nuclear propulsion policy, will adopt natural gas as the center of its electrical power policy, providing preferential treatments such as subsidies and tax exemptions and requesting the power companies to increase their usage. This will lead to higher transmission charges, with distributed power generation more advantageous to the IPPs in terms of cost. In the scenario 3, environmental awareness will make increase in the capacity quite difficult including power generation facilities and transmission/distribution network, and will invite a power crisis in the long run through insufficient capacity in power generation and transmission/distribution volume. Distributed power generation requiring no reinforcement to the grid will spread such as household-use type without system interconnection, solar cells or small fuel cells. (NEDO)

    It was previously reported that the tritium tracer method is useful for the quantitative consideration of hydrogen behavior in coal during coal liquefaction reaction. Tetralin is excellent hydrogen donating solvent, and is considered as one of the model compounds of coal. In this study, effects of H2S and H2O on the hydrogen exchange reaction between tetralin and gaseous hydrogen labeled by tritium were investigated. It was suggested that the conversion of tetralin and the hydrogen exchange reaction between gaseous hydrogen and tetralin proceed through the radical reaction mechanism with a tetralyl radical as an intermediate product. When H2S existed in this reaction, the hydrogen exchange yield increased drastically without changing the conversion yield. This suggested that the hydrogen exchange reaction proceeds even in the reaction where radical does not give any effect. In the case of H2O addition, the conversion yield and hydrogen exchange rate decreased into a half or one-third. It was suggested that H2O inhibited the formation process of tetralyl radical. 6 refs., 4 figs.

    The feasibility study was conducted on a project in China for energy saving and greenhouse gas emission reduction by introducing the energy-saving and alternative energy technologies in cement plants. The cement plant selected for the feasibility study is Shanghai Plant of Shanghai Allied Cement Co., Ltd. (SAC), for RDF receive and supply facility, chlorine bypass facility, exhaust heat power generation facility and RDF production facility. The study results indicate that the exhaust power generation can save energy of 4,700 tons/y as crude, or energy saving rate of 25.5%, and that replacing part of coal by RDF and exhaust power generation can reduce CO2 emissions by 25,500 and 18,500 tons/y, respectively. For the investment recovery, it is estimated that the investment can be recovered in 9 years, and the project value is 81.399 million Yuan with the initial investment and project profit in each year discounted to the present value. These results fail to satisfy the SAC's investment standards. (NEDO)

    Under the secondary interim assessment made in FY 1995 between the assessment committee of the energy/environment technology development sectional meeting of the Industrial Technology Deliberation Council and NEDO, in this project, the following were conducted in FY 1996: study of trial manufacture of superconductor motor model machine and R and D of element technology (conductor technology/refrigerator technology). The study was proceeded mainly with Super-GM, and as to the motor, the preparation for test on a part of the model machines was finished. Considering FY 1998 which is the final year of this project, the investigational study in FY 1996 aims at accumulating/arranging/analyzing the data which help judge how to proceed with the future R and D of superconductor power application technology continuously based on the secondary interim assessment. For superconductor motor and various superconductor power appliance, economical/technical feasibilities and methods of R and D and surveys of trends in Japan and abroad for the R and D were made important items. Further, 'R and D of the basement of superconductor power application' proposed in the secondary interim assessment (R and D of the combination of elements which become the basement of equipment technology over a stage of parallel R and D of element technology of conductor, etc.) targeted the presentation of concrete details.

    For construction of a sustainable society by active use of bio-technology, a research study was made on the current state of active use of bio-technology for every industrial or social field, and the basic recognition and orientation for practice and diffusion of bio-technology. The previous typical examples of the effect of bio-technology on energy and social systems were evaluated from not only an affirmative viewpoint but also a compensatory viewpoint. Based on these examples, promising features of bio-technology and measures for active use of such features were showed for the future energy and social systems from a technological viewpoint. As a scenario for sustainable development of a society, some approaches and values about collection of rare resources, agriculture based on mass circulation, and recurrence to high-protein traditional foods such as fermented food were showed for balanced development of environment, population, and resources including energy and food. 8 refs., 14 figs., 8 tabs.

    Xe/Ne plasmas are important for plasma display panels and VUV light sources. However, reactions between electrons and excited particles in the mixtures are so complicated that influence of the reactions on the plasma properties is not understood well. In this work, taking account of reactions through which electrons are produced, such as cumulative and Penning ionization, and of transition between excited levels, the electron and excited particle properties in Xe/Ne plasmas are calculated using the Boltzmann equation. The ionization coefficient and electron drift velocity agreed with experimental data. The influence of laser absorption in Xe/Ne plasmas on the plasma properties is also discussed. 25 refs., 15 figs.

    In this study, after having performed simulation which took up scale models substituting for full scale model of commuter car made of FRP, we carried out collision tests to barrier. Here, we made enquiries about the occupant safety by changing the collision speed and the deformation characteristics of the seat belt, during head-on barrier collision using one-fifth scale models. We sought for the occupant`s safe combinations among the deformation characteristics of airbag and the thorax deformation. In this case, the degree of the occupants injury were estimated using HIC values, 3msecG and maximum deformation of the thorax. 7 refs., 5 figs.

    A method for curing CFRP composite structures by using Joule effect is presented. Due to the presence of fiber to fiber contact, CFRP composites and their prepregs exhibit electrical conductivity in the direction transverse to fibers as well as in the fiber direction, and they can be considered as electrically homogeneous on a gross scale. Therefore, passing an electric current through a CFRP prepreg, it is self-heated due to the Joule effect. Feedback current control maintains the prepreg temperature at a desired level and makes the prepreg be cured by a specified cure cycle. Experimental verifiactions have been carried out to demonstrate the feasibility of the present technique. The applications to the bonding of CFRP components and to the patch repairs of effective CFRP structure are also described. 12 refs., 12 figs.

    In order to make alkaline manganese batteries mercury-free and suppress hydrogen gas generation, investigations were given on the effect of additive species on modification of zinc particles present on negative electrode surface. Mercury with high hydrogen overvoltage has been added conventionally, but the mercury can cause an environmental problem. Surface modification by using indium exhibited hydrogen gas generation suppressing effect. With the surface modification amount of 0.10% by weight or more, the suppressing effect is saturated, reducing the effect to 50% of that of mercury. Surface-modifying the bismuth added zinc particles with indium showed greater suppressing effect than the case where each element is used independently. Zinc-indium (0.10% by weight) - bismuth (0.025% by weight) based alloy powder showed the same hydrogen generation suppressing effect as zinc-mercury (0.15% by weight) alloy powder. A sealed test battery using this alloy powder in negative active material exhibited a discharge capacity of 1700 mAh similarly to the initial stage even after having been stored for 20 days at 60 degC. Self-discharge characteristics equivalent to that of zinc-mercury (0.15% by weight) based alloy powder were obtained. An environment compatible dry cell battery containing no mercury whatsoever was developed successfully. 18 refs., 6 figs., 1 tab.

    Concerning the district in Osaka Prefecture selected for study in fiscal 1997, it is investigated whether energy efficiency is enhanced, and environmental impact reduced, by the introduction of element technologies, and the findings are compared with the results expected to be produced without their introduction. Problems about their introduction are also discussed. Taken up for study are the collection and utilization of heat from a water granulated slag manufacturing plant of an iron mill, exhaust heat reform and recovery system at a chemical plant, heat supply system driven by a high-performance heat pump capable of dealing with various kinds of fuels, compression/suction hybrid heat utilization system, and a cold heat supply system using microspheres. Annual energy consumption, CO2 and NOx emissions, and costs are calculated for each of them. Concerning these element technologies, various tasks are discussed, related to the technology of their systematization, economy, dissemination of district heat supply, and wide-area heat supply businesses utilizing exhaust heat. As the result, it is concluded that the primary energy consumption as a whole is reduced upon their introduction and that energy saving effect and environmental impact reducing effect are in presence.

    Limestone immersion into heat-storage water tanks is a method for improving the water quality so as to encrust inner surface of piping by corrosion-preventive calcium carbonate film. For air-conditioning of Support city subway stations, heat-storing heat-pump systems with heat recovery from exhaust air have been introduced and developed for energy saving along with expansion of the subway routes. Inner surfaces of the heat-storage water tanks of all stations are coated with FRP-lining, therefore, some corrosion-preventive chemicals had been dosed from the starting up. However, the storage waters of all stations turned to red because of continuity of the piping corrosion. Instead of dosing chemicals, the limestone immersion method station. Thanks to His method, excellent results were obtained in a short period contributing control of the piping corrosion together with the red water fading. 14 figs., 1 tab.

    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)

    A survey is conducted of the actual state of leaks from natural gas pipelines and of the energy-saving and greenhouse gas-reducing effects of pipeline rehabilitation, with the clean development mechanism (CDM) borne in mind. Comilla and Chittagong are the areas that are covered by the survey. Natural gas leaks from the main pipelines BC and BD are calculated to be 5,300 and 5,600 tons/year, respectively. Total leakage across the country is estimated at 85,000 tons/year. Approximately 41% of the imbalance is explained by leakage while the rest is attributable to errors in gas flow measurement etc. The total leakage from branch pipelines is approximately three times larger than that from main pipelines, and some measures need to be taken to remedy the situation. For the densely populated city of Dhaka which finds itself in a network of branch pipelines, in particular, rehabilitation and optimization of its accessory power stations etc. are quite important. Measures for leakage if properly implemented will not only reduce the amount of leakage but also prevent ignition or explosion for the minimization of economic loss and for the assurance of safety. Error-free gas flow measurement if realized will strengthen the foundation on which sales are performed. (NEDO)

    The United Nations Framework Convention on Climate Change is studied from the viewpoint of implementing costs. As far as the global warming issue is concerned, the factor to affect the environment is not the emitted volume but the concentration in the air. The ultimate target is the stabilization of greenhouse gas concentration at a level not to impose serious artificial damage on the ecosystem. Accordingly, various time paths are considered, including one in which much emission is allowed at the beginning and suppression is enforced acceleratedly in the later stage. In this study, a path demanding but the minimal cost in the period up to the target time point is discussed, using as the tool the marginal cost for measure implementation. In a reasonable emission control strategy, the emission control marginal cost follows a time path that is dependent upon an increase function to be determined by the discount rate and survival rate (time constant) in the atmosphere. In the industrial branch, instead of imposing short-term and rigid emission volume control limits, a longer-term target may be set for reduction in the loads responsible for concentration acceleration, concrete emission controls under the given conditions may be implemented at the discretion of the implementing organizations, and reduction in cost may be realized by time distribution with the environmental impacts kept at approximately equal levels. 5 refs., 2 figs., 3 tabs.

    This paper presents power load leveling and energy saving measures for heat source, air conditioning and lighting of the new Kobe branch building. The low-temperature hot-air system adopts an ice storage system, and reduces blowing power by 12 degreesC blowing in place of normal 16 degreesC blowing, and an initial cost by duct size reduction. The continuous air conditioning system levels an initial peak load of air conditioning as compared with normal air conditioning only for working hours for buildings with large heat capacity. In addition, as power load leveling measures for the whole building, the complete heat storage system using an underground internal melting type ice storage tank is adopted. Energy saving for lighting is achieved with a dimming lighting controlling its lighting output by inverter. The following effects are expected by these new technologies: Load leveling effect of 30%, energy saving effect of 20.2% and CO{sub 2} reduction effect of 24.1%. (NEDO)

    It has been clarified that the use of some kinds of semiconductor films, such as a rutile type titanium oxide film or a zirconium oxide film, results in a stable photocatalytic reaction in an intensive radioactivity region. In this effort, the effect is applied for the development of a FET (field effect transistor) type radiation detector capable of stable operation under high dose irradiation circumstances. Semiconductor materials such as a rutile type titanium oxide were subjected to irradiation tests on the ground, in which changes in their physical properties such as wettability or conductance were examined and the mechanism of surface reforming under irradiation was elucidated, and proper materials were selected. A prototype high radiation detector was fabricated that covers a 1mGy/hr-4kGy/hr region. For the establishment of a technology for growing spherical semiconductor crystals under microgravity, basic experiments were conducted using a free-fall facility at the Japan Microgravity Center. Basic experiments were conducted for the fabrication of a prototype radiation detector to operate in a high radiation region from 0.1kGy/hr to 2kGy/hr and beyond, and a prototype spherical semiconductor radiation detector was fabricated. Achievements of the effort are mentioned above. (NEDO)

    A geotextile drainage material called ART-DRAIN has been developed. It was applied to temporary roads in a tunnel, to evaluate its permeability through a long-term permeability test using a model. The ART-DRAIN is a drainage material for protecting the roads from muddy conditions in a tunnel due to spring water. A filter for permeating fine soil particles was employed to keep the permeability. From the long-term permeability test using a model, appropriate permeability of ART-DRAIN was maintained for three years without blinding. There was only a slight inflow of fine grain soils into the ART-DRAIN. It was confirmed that the permeability was not obstructed by the fine grain soils. The ART-DRAIN was applied to tunnel construction works for the high-speed railway in Kyoto and the national road in mountains. From these applications, factors for enhancing the permeability effect were confirmed, which includes the selection of high quality muck, insurance of the road-bed strength by the initial compaction, use of road drainage materials with high compressible property and permeability of filter, and intervals of drainage. 1 ref., 19 figs., 1 tab.

    In recent years, oxygen-deficient water is being formed in many semi-enclosed waters, such as canals and ports, due to the load from rivers in addition to oxygen consumption in bottom sediment and poor water circulation. In general, bottom sediments have been dredged in order to improve the water environment. But there is little space to dump it. An alternative method is to artificially promote water circulation in order to move the surface water that has a high dissolved oxygen concentration to the bottom. We applied the method in a port. The system consists of air compressors, rubber tubes and unique pipes. One end of a pipe was fixed on the bottom and the other end was kept in the water by floats. Air floated up through the pipe, so the bottom water flowed up to the surface. Two months after starting to run the system, the dissolved oxygen concentration of lower water was higher than 2 mg/l, which is the criterion of water quality standard grade V, thus showing the effectiveness of the system.

    A feasibility study is conducted of the above-named system in Malaysia, to be linked to COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) clean development mechanism (CDM). The dual mode bus system (DMBS) is a combination of advantages of the rail running stock such as monorails and the road running stock in that the buses when running on dedicated roads are automatedly formed into a linear formation and travel at a specified economical speed. When running on ordinary roads, the formation is broken into individual buses, and they spread in the town where they travel in a planar pattern. The economical speed and reduction in air drag thanks to the linear formation saves fuel and reduces CO2 emissions. The complementary relationship to be formed with the existing public transportation systems will also function positively. Studies are conducted on condition that two routes be laid in the Kuala Lumpur urban area and one in the new city Putra Jaya. All the three routes exhibit a high economic internal rate of return, but their financial internal rate of return indicates that probabilities are low that they will pay as private businesses. They will need financial supports such as subsidies. Contribution to CO2 reduction may be slight when attention is paid only to the partial changeover from the existing bus system to DMBS but larger contribution will be found in crossover from private cars to DMBS which is higher in quality of service.

    Emissions trading of greenhouse gases is going to be introduced to give flexibility to the method of achieving reduction of the greenhouse gas emission established in the Kyoto Protocol. The emissions trading is an institution intended to achieve the environmental targets by using the 'market mechanism' in the environmental policies, which is expected to accomplish the effect of reducing greenhouse gas emission. The U.S.A. has adopted since 1990 the policy utilizing the emissions trading on SO2 and NOx, creating cases of successfully achieving the initial regulation targets in a short time. The history of this SO2 emissions trading showed that the emissions trading that makes the market mechanism to function can function as a policy even in the environmental policy. The representative of business enterprises working actively on this issue is BP Amco. BP Amco has started January 2000 full-fledged greenhouse gas right-to-emit institution inside the company. Among electric power companies, Ontario Power of Canada has executed about ten greenhouse gas emissions tradings yearly. Enron International has structured a system in order to participate positively in the greenhouse gas trading. (NEDO)

    This paper describes a method for evaluating grouting that is a means for improving the ground for excavation for building underground structures in urban areas. This is an effort for improving reliability, and evaluates the rate of filling of the water glass base chemical liquid injected for improving the ground utilizing the fact that this liquid is higher in conductivity than the soil or ground water. An experiment was conducted using a model ground so as to define the limit of applicability of this resistivity tomography by studying electrode arrangements and difference in resistivity between the grouted liquid and ground water. It was then found that the liquid-injected region is evaluated more accurately when the measuring electrodes are installed nearer to the region, that evaluation is satisfactorily accomplished when the region spans not less than 75% of the distance between the electrodes, that higher accuracy is expected when the difference in resistivity is greater between the grouted liquid and ground water, that evaluation is satisfactorily accomplished when the resistivity of the grouted liquid is not more than 10% of that of ground water, and that any grouting liquid usable for ground improvement in civil engineering in urban areas can be applied to any other grounds except where there is influence of seawater. 31 refs., 55 figs., 8 tabs.

    This report introduces regional heat supply systems using unused energy in Japan and overseas. Evaluation examples of their CO2 reducing effects are arranged. The introduction effects were quantitatively evaluated in some urban areas in Tokyo. For the evaluation, not only the conventional energy efficiency but also energy saving and CO2 reducing effects secondarily derived from the release of a rise of temperature in urban areas were quantified, to investigate their economy. Synthetic introduction effects were estimated. As a result of the case study, the system was confirmed to be a prospective option to make CO2 reduction more than 10% in the target district. Particularly in summer, about one-fourth of the effect was brought by the restriction of heat island phenomenon. When soil heat source type district heating and cooling system was applied to the whole redevelopment area, it was found that CO2 reducing effect of the whole Tokyo is only less than 0.1%. 40 refs., 64 figs., 43 tabs.

    Under the secondary interim assessment made in FY 1995 between the assessment committee of the energy/environment technology development sectional meeting of the Industrial Technology Deliberation Council and NEDO, in this project, the following were conducted in FY 1996: study of trial manufacture of superconductor motor model machine and R and D of element technology (conductor technology/refrigerator technology). The study was proceeded mainly with Super-GM, and as to the motor, the preparation for test on a part of the model machines was finished. Considering FY 1998 which is the final year of this project, the investigational study in FY 1996 aims at accumulating/arranging/analyzing the data which help judge how to proceed with the future R and D of superconductor power application technology continuously based on the secondary interim assessment. For superconductor motor and various superconductor power appliance, economical/technical feasibilities and methods of R and D and surveys of trends in Japan and abroad for the R and D were made important items. Further, 'R and D of the basement of superconductor power application' proposed in the secondary interim assessment (R and D of the combination of elements which become the basement of equipment technology over a stage of parallel R and D of element technology of conductor, etc.) targeted the presentation of concrete details.

    For the purpose of reducing the CO2 emitted from electricity/vapor supply facilities of Bataan Refinery in the Philippines, study was conducted of optimum energy supply facilities considering the effective use of the oil residue and future reinforcement of the refinery. Concerning the high-pressure/high-temperature condensing extraction boiler/turbine cogeneration, gas turbine cogeneration and low speed diesel engine cogeneration, comparative study was carried out in terms of thermal efficiency, reliability/preservation, environmental acceptability, effectiveness of measures for the future excessive oil residue, etc. As a result, the study was concluded as follows: the electric power consumption will markedly increase in the future; however, in the light of the situation of the refinery where the vapor demand will not increase, it is the most suitable to use low speed diesel engine cogeneration facilities as on-site power generation facilities which can burn the excessively increasing oil residue as direct fuel. The CO2 reduction effect estimated from the project on the present scale was 132,880 t-CO2/y, and the energy conservation effect estimated was 50,861 toe/y. (NEDO)

    Effects of the transfer of environmental technology were studied as an important policy for control of greenhouse effect gas in the Asian region. As schemes, those that were drew up by NEDO, JICA, etc. now exist and are used also in Japan. However, for the control of greenhouse effect gas emission which is expected to rapidly increase in future, it is indispensable to construct a new powerful and effective scheme in which technology transfer and fund to be given are organically connected. Especially, in the U.S., etc., the assistance of developing countries of a huge amount of money such as Japan's ODA is not extended. However, they position the environmental technology as an important strategy and is developing the assistance of developing countries by technology transfer and eco-business of private companies. Also in the eco-business field, the environment-related technology of Japanese companies is used in Asian developing countries, with expectations of its being a new business with international competitive strength. This is the subject for the whole global environment, and an important subject also for Japan which requires the creation of a new business field with international competitive strength. (NEDO)

    By the use of superconductive technology, the following are aimed at: marked reduction in power loss of electrical equipment and power transmission path, and size/weight reduction in electrical devices by high current/magnetic flux density. The superconductive technology has advantages such as great energy saving effect, CO2 reduction and global environmental preservation. As an example, concerning the superconductive generator now being developed under the New Sunshine Project, power loss can be reduced by half, and by the use of high magnetic field, size/weight can be reduced such as reduction in rotor diameter and reduction in weight by half. Further, as an innovative system, cited are the superconducting magnetic energy storage system (SMES) and flywheel energy storage system. The superconducting magnetic levitation railway, medical use MRI, etc. have also innovativity which is difficult to get in the conventional technology. Effects are also expected of introducing the process development using superconducting magnet such as magnetic separation, electromagnetic metallurgy, electromagnetic agitation and monocrytal growth convection control. Also cited is Josephson electronic device. High performance SQUID in bio-magnetic/non-destructive inspection is also expected to be developed. (NEDO)

    The depression of the reaction between SiC and Ni, by adding TiO2 powder in spraying powder which has caused uniform dispersion in spray coating and reduction of TiO2 by the reaction during spraying, was studied. The mass ratio of the mixed components has been, SiC:Ni:TiO2=3:2:1. The spray coating was examined by electron prove microanalysis as well as X-ray diffractometry, centering mainly to the SiC-metal interface reaction. The formation of Ni-Si compounds have been depressed by the addition of TiO2 to spraying powder and by using plasma gas containing H2. Reason for this has been that the TiC formed in the SiC-Ni interface has depressed the reaction at the SiC-Ni interface. Further, TiO2 is reduced during spraying, and TiC is thought to be formed by the reaction between Ti and SiC or reaction between TiO2 and SiC. 8 refs., 6 figs., 1 tab.

    The R and D project is implemented for design, fabrication and installation of ocean-based artificial deep ocean water (DOW) upwelling devices which can take DOW at low cost in an ocean; experiments for enhancing productivity of ocean by adding DOW using mesocosms; and studying the biological effects of DOW for keeping freshness of marine products. DOW is successfully taken by the upwelling system from a depth of 800 m in a sea area 2,000 m or more in depth. The system has worked to perform its functions even when attacked by typhoons, which caused wave height of 10 m or more. For enhancing productivity of ocean, the culture experiments are conducted in a small-size, on-shore tank, and the mesocosm experiments in a harbor. The results indicate that addition of DOW increases the phytoplankton phase and its quantity. It is also observed that addition of iron ion further accelerates the fertilizing effect. The results of the experiments conducted in a harbor also indicate that DOW has the fertilizing effect, even in a very small quantity, increasing quantity of small zooplankton. No definite effect of DOW, liquid or ice, is observed for keeping freshness of sliced raw sea bream and bonito. (NEDO)

    To evaluate critical trace element loads in native vegetation and calculate soil-to-plant transfer factors (TFs), 11 trace elements (Cr, Co, Ni, Cu, Zn, As, Se, Mo, Cd, Pb and Mn) have been determined in leaves of 9 taxonomically verified naturally growing terrestrial plant species as well as in soil samples collected around 3 Ethiopian Rift Valley lakes (Koka, Ziway and Awassa). The Cr concentration in leaves of all the plant species was higher than the "normal" range, with the highest level (8.4 mg per kg dw) being observed in Acacia tortilis from the Lake Koka area. Caper species (Capparis fascicularis) and Ethiopian dogstooth grass (Cynodon aethiopicus) from Koka also contained exceptionally high levels of Cd (1 mg per kg dw) and Mo (32.8 mg per kg dw), respectively. Pb, As and Cu concentrations were low in the plant leaves from all sites. The low Cu level in important fodder plant species (Cynodon aethiopicus, Acacia tortilis and Opuntia ficus-indicus) implies potential deficiency in grazing and browsing animals. Compared to the Canadian environmental quality guideline and maximum allowable concentration in agricultural soils, the total soil trace element concentrations at the studied sites are safe for agricultural crop production. Enrichment factor was high for Zn in soils around Lakes Ziway and Awassa, resulting in moderate to high transfer of Zn to the studied plants. A six step sequential extraction procedure on the soils revealed a relatively high mobility of Cd, Se and Mn. Strong association of most trace elements with the redox sensitive fraction and mineral lattice was also confirmed by partial redundancy analysis. TF (mg per kg dw plants/mg per kg dw soil) values based on the total (TF(total)) and mobile fractions (TF(mobile)) of soil trace element concentrations varied widely among elements and plant species, with the averaged TF(total) and TF(mobile) values ranging from 0.01-2 and 1-60, respectively. Considering the mobile fraction in soils should

    Full Text Available We report about testing a new mobile and sustainable water sample digestion method in a preliminary field trial in Ethiopia. In order to determine heavy metals at the ultra-trace level by stripping voltammetric techniques in water samples from Awash River, we applied our new method of solar UV-assisted sample pretreatment to destroy the relevant interfering dissolved organic matter. The field tests revealed that 24 h of solar UV irradiation were sufficient to achieve the same sample pretreatment results as with classic digestion method based on intense and hard UV. Analytical results of this study suggest that both a hydroelectric power station and agrichemical applications at Koka Lake have increased the levels of the investigated metals zinc, cadmium, lead, copper, cobalt, nickel, and uranium.

    Malaria is associated with dams because their reservoirs provide mosquitoes, the vector of malaria, with permanent breeding sites. The risk of contracting malaria is likely to be enhanced following the increasing trend of hydropower dam construction to satisfy the expanding energy needs in developing countries. A close examination of its adverse health impacts is critical in the design, construction, and operation phases. We will present results of extensive field studies in 2012 and 2013 around the Koka Reservoir, Ethiopia. The results uncover the importance of reservoir management especially after the rainy seasons. Furthermore, we show the capability of a newly modified hydrology, entomology and malaria transmission simulator, HYDREMATS (Bomblies et al, 2008), and its potential as a tool for evaluating environmental management strategies to control malaria. HYDREMATS was developed to represent how the hydrology in nearby villages is impacted by the reservoir system, and the role of different types of vector ecologies associated with different Anopheles mosquito species. The hydrology component of HYDREMATS simulates three different mosquito breeding habitats: rain-fed pools, groundwater pools, and shoreline water. The entomology component simulates the life cycles of An. funestus and An. arabiensis, the two main vectors around the reservoir. The model was calibrated over the 2012-2013 period. The impact of reservoir water level management on the mosquito population is explored based on numerical model simulations and field experiments.

The present study attempts to analyze the motivation of adolescent basketball and football players from the perspectives of Achievement Goal Theory (Nicholls, 1989 and Self-Determination Theory (Deci & Ryan, 1985. The study's sample was composed of 248 athletes from 12 to 17 years of age. Half were from basketball and half were from football. The instruments that were utilized were: the Spanish version of the Sport Motivation Scale (SMS (Núñez, Martín-Albo, Navarro, & González, 2006, the Spanish version of the Perceived Motivational Climate in Sport Questionnaire-2 (PMSCQ-2 (Balaguer, Mayo, Atienza, & Duda, 1997, and the adapted Spanish translation (Moreno, Moreno, & Cervelló, 2007 of the Intention to be Physically Active Scale (IPAS by Hein, Müür, and Koka (2004. The comparison of the means of the variables between football and basketball players was done utilizing the student t-test for independent samples. Significant differences were found for variables such as: intrinsic motivation (IM toward accomplishment, external regulation, amotivation, task, ego, and Self-Determination Index (SDI. Basketball players obtained higher values in the SDI, in task, and in IM toward accomplishment than football players. The search for premature performance in football and coaches' educations can help to explain these differences. The importance of these differences reside in the relationship between these motivational variables and the adherence to athletic practice. In conclusion, basketball demonstrated better values in motivational variables, which demonstrates that training sessions are more oriented toward task than ego, that players have more intrinsic and self-determined motivation, and therefore, the adherence of the young athletes will be greater in this sport.

    Japanese social security systems and institutions for the elderly, as well as the general attitude toward elderly care services among the Japanese population, have been undergoing a dramatic change. By examining the association between institutional trust, which is a representative element of social capital, and anxiety regarding receiving elderly care, we can uncover clues toward building a more robust social security system for the elderly. This study examines the relationship between institutional trust, in the national social security and municipal healthcare systems for the elderly, and anxiety with respect to receiving elderly care among the general Japanese population. A cross-sectional survey was conducted using a self-administered questionnaire that was returned by mail in January and February 2005. The target population was 4735 community residents aged 20-75 years, who lived in the city of Koka, Shiga, Japan. A total of 2264 questionnaires were included in the analysis. A binominal logistic regression analysis showed that responses of 'trust' [odds ratio (OR): 2.09, 95% confidence interval (95% CI): 1.01-4.30] and 'strongly trust' (OR: 3.80, 95% CI: 1.55-9.31) for the national system were associated with not having anxiety regarding elderly care, compared with the reference category of feeling strongly distrust. However, trust in the municipal system showed no association with this anxiety. These results indicate the importance of developing strategies to increase a common trust in the national care services for the elderly to reduce the anxiety people feel regarding whether they will be able to receive elderly care when required.

    Full Text Available Em mercados cada vez mais dinâmicos e turbulentos, as organizações dependem cada vez mais do conhecimento externo, recurso essencial no centro das estratégias organizacionais, como forma de promover a inovação e melhorar seu desempenho (Ireland, Hitt, & Vaidyanath, 2002; Zollo, Reuer, & Singh, 2002; Cassiman & Veugelers, 2006; Morgan & Berthon, 2008; Lichtenthaler, 2009. A capacidade de absorção (absorptive capacity – Acap traduz-se como um dos processos-chave de aprendizagem das organizações no que diz respeito à identificação, assimilação e exploração dos conhecimentos do ambiente (Cohen & Levinthal, 1989; Lane, Koka, & Pathak, 2006. Apesar de um considerável número de estudos empíricos ter usado a Acap, uma medida válida que incorpore essas várias dimensões ainda não foi desenvolvida (Wang & Ahmed, 2007. Lane et al. (2006 observam que a maioria dos pesquisadores tipicamente mede a Acap como simples proxies de P&D (por exemplo, Cohen & Levinthal, 1989, ignorando a variedade de suas dimensões e suas implicações para os diferentes resultados organizacionais. Não obstante, poucos estudos empíricos têm capturado a natureza multidimensional da Acap (Jansen, Van Den Bosch, & Volberda, 2005. O presente estudo verifica a influência da Acap no desempenho organizacional sob diferentes condições de turbulência ambiental. Trata-se de um estudo descritivo do tipo levantamento ou survey, com corte transversal. A população-alvo da pesquisa foi composta por empresas de varejo na região da Grande Florianópolis, com pelo menos um ano de atividades ininterruptas. Os dados foram coletados por meio de questionários autoadministrados e respondidos pelo principal dirigente das empresas, quando possível, ou por alguém responsável pelo estabelecimento. Além disso, diferentes características de moderação, como idade e tamanho das organizações, são consideradas. Os resultados a partir de 230 empresas varejistas mostram
