    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.

    1997-05-27

    This paper describes concept of subsurface micro-sensing. It is intended to achieve an epoch-making development of subsurface engineerings by developing such technologies as micro measurement of well interior, micro measurement while drilling (MWD), and micro intelligent logging. These technologies are supported by development of micro sensors and micro drilling techniques using micro machine technologies. Micronizing the subsurface sensors makes mass production of sensors with equivalent performance possible, and the production cost can be reduced largely. The sensors can be embedded or used disposably, resulting in increased mobility in measurement and higher performance. Installing multiple number of sensors makes high-accuracy measurement possible, such as array measurement. The sensors can be linked easily with photo-electronics components, realizing remote measurement at low price and high accuracy. Control in micro-drilling and MWD also become possible. Such advantages may also be expected as installing the sensors on the outer side of wells in use and monitoring subsurface information during production. Expectation on them is large as a new paradigm of underground exploration and measurement. 1 fig.

    It is predicted that there will be many changes in environment of electric utilities such as expansion of electric power demand, spread of distributed power sources, and changes in market structures due to deregulation. As a first step to think about future telecommunication networks which respond to these changes and adopt technical innovation of telecommunication, present conditions and problems of the current utility telecommunication network are outlined. The utility telecommunication is characterized by high reliability and existence of the information that requires strict transmission delay restriction. The following points are given as the future subjects: although most utility telecommunication networks currently consist of leased lines, they have to be changed to the switched networks for diversifying telecommunication service. It should be considered that the leased line network, which has a hierarchical structure based on a geographical extent, will have a hierarchical structure that is able to correspond to the future telecommunication service. It is better for the current individual loop shape with dual telecommunication circuits to be changed into the overall link shape. In introducing the ATM transmission to improve the path efficiency, it is a premise to secure reliability. 8 refs., 7 figs., 7 tabs.

    This paper summarizes the water monitoring system (WMS) in China applied mainly to surface water and operated within the competence of the Environmental Protection Agency. The WMS consists of a national water monitoring network and a water information system that monitors surface water periodically. The WMS comprises water monitoring stations classified from class 1 to class 4, which are located in 2,222 locations. Stations from class 1 to class 3 are operated by using computers, but class 4 stations are still incapable to use floppy disks to perform information transmission. When an information management system is completed at the China-Japan Friendship Environmental Protection Center being constructed by gratis assistance from the Japanese Government, transmission of water quality data will become possible by means of the cable line system in addition to the table system and the floppy system. The water quality data are published to general people in the forms of Chinese gazette for the environmental conditions, the environment yearbook, and the reports on environmental quality. However, the more important is to publish more publications to make people aware of the actual state of water pollution and have them cooperate in environment preservation. 4 refs., 1 fig.

    Conventional host-based central-processing type logistics information systems collect all information about stocked products (sales results, inventory, out-of-stock items) on a single host computer, and based on this information perform ordering, shipping, receiving, and other processing. In a client/server architecture, the system is not simply downsized: in order to ensure more effective use of logistics information and closer coordination with manufacturing information systems, the logistics information system must be configured as a distributed system specific to a given factory and its various products. Such distributed systems each function acts independently, but at the same time the overall system of which they is part must operate in harmony to perform cost optimization, adjust allocation of resources among different factories and business locations, and present a single monolithic interface to retailers and sales agents. In this paper, we propose a logistics information system with a distributed architecture as well as agents whose role is to coordinate operation of the overall system, as one means of realizing this combination of component autonomy and overall system harmony. The methodology proposed here was applied to a proving system, and its effectiveness was verified. 9 refs., 12 figs.

    1996-02-01

    In petroleum complexes and chemical complexes in which the control of operation of the plants is being automated, most of the accidents recently occurring are accidents occurring during, especially, works which are difficult to automate, such as non-steady work and maintenance work rather than accidents ascribed to erroneous operation. The number of aged facilities has increased, and the facility maintenance work tends to be subcontracted increasingly. The facility engineering will become a still more important problem in the future. The High Pressure Gas Safety Institute of Japan has issued a compendium on the safety of high pressure gas every year since 1987, and they issued a collection of examples of accidents in complexes in 1991. This paper introduces main examples of the accidents concerning the facility maintenance, extracted from the accident information recorded in the compendium and the collection of examples of accidents. Finally, lessons learned from the accident information are enumerated, and future problems are posed which include subcontraction of the facility maintenance work, the facility management cost and the facility safety. 6 refs., 1 fig., 1 tab.

    We analyzed the signal transduction in brain neurons by real-time imaging of Ca/NO signals using the Molecular Signal Microscope. We also analyzed synthesis and action of neurosteroids in the hippocampus. We discovered steroid synthesis machinery containing cytochrome P 450 scc in hippocampal neurons. We found that pregnenolone sulfate acutely potentiated NMDA receptor-mediated Ca conductivity in hippocampal neurons. We also found that stress steroid corticosterone acutely prolonged NMDA receptor-mediated Ca{sup 2+} influx, resulting in Ca-induced neuro-toxicity. (author)

    To examine the functional roles in vivo of the diverse glutamate receptor (GluR) channel subunits, we generated mutant mice defective in respective subunits. Mutant mice defective in the GluR{epsilon} 1 subunit of the NMDA-type GluR channel exhibited increased thresholds for both hippocampal synaptic plasticity and contextual maze learning, suggesting that synaptic plasticity is a cellular bases of learning and memory. The NMDA receptor channel GluR{epsilon} 2 subunit mutant mice showed impairments in the formation of the whisker-related neuronal barrelette structure in the brainstem trigeminal nucleus and synaptic plasticity in the hippocampus. Analyses of the mutant mice revealed that the GluR{delta} 2 subunit, selectively localized in cerebellar Purkinje cells, was essential in motor learning and cerebellar LTD and in Purkinje cell synapse formation. Our results suggest that some of the GluR channels play important roles in neural network formation during brain development and in higher brain function. (author)

The basic technology of security management is classified into the `user certification to prevent an incorrect access` and the `encipherment to prevent data from being used incorrectly.` The technology for certification has been almost completed. It can be securely done using an expendable password or IC card system. In Internet, multiple enciphering technologies for constructing a virtual private network that can secure the almost the same security as for a private network can be used. In an electronic mail, the enciphering technology can also be used easily. The tool that manages the security of very many servers, clients, and networks is in the initial stage. 16 refs., 1 fig., 5 tabs.

    In relation to information processing in the open type research information networking, R and D were conducted to establish basic technologies such as grading-up, acceleration, enhancement of efficiency, diversification of application, promotion of usable data accumulation, etc. As to the R and D of software to promote sharing of research information, software was developed which can easily modify and renew management objects for users at research sites, etc., and the target was almost achieved. Concerning the R and D of information supply technology, an approach was presented whereby clients submit bids for each stream of the data requested and the admission decision is made so as to maximize gain of the session under network capacity constraints. Additionally, the R and D were made of software to construct an international information sharing system, a system for multi-lingual I/O, text manipulation and communication, and software for remote use of network based information for scientific computing. 138 refs., 125 figs., 33 tabs.

    For planning the Pacific area energy policy of Japan, the field survey on energy situations was carried out in Laos and Myanmar. Since Laos is rich in hydraulic resources, the future electric power development is expected. Development of oil and coal resources is yet in a planning stage. Electricite du Laos (EdL) is in charge of electricity business, and its power generation capacity amounts to 220MW (including hydroelectric one of 93%), and a half of it is exported. Based on the predicted growth rate of 9%/y for domestic power demand, development of the capacity to 440MW by fiscal 2002 is scheduled. Myanmar has natural gas and various mineral resources, and is rich in hydroelectric resources. Myanmar Electric Power Enterprise (MEPE) is in charge of electricity business. The power generation capacity amounts to 1.34GW (including private one of 26%). The power generation facility is composed of gas turbine one of 53% and hydroelectric one of 33%. Based on the predicted growth rate of 11.5%/y for domestic power demand, development of the capacity to 1.6GW by 2001 is scheduled. For the present, conversion of previous gas-firing power plants to efficient combined cycle ones is a main issue. 21 figs., 43 tabs.

    The paper investigated/studied `space light modulation materials,` `dynamic hologram/memory materials,` `optical waveguide path materials,` etc. which become key materials in the high speed two dimensional processing. As to electrooptical materials proposed in this investigational study, the external electric field and the electric charges generated make quality of molecules themselves directly change to memory strong/weak signals of light. Therefore, the response velocity becomes less than a millionth of that of the liquid crystal display, and high speed which is needed for realtime moving image processing is anticipated. Hologram includes the phase information in addition to information on light strength. Therefore, it is a large capacity record medium and at the same time a record medium which can read/write two dimensional information as it is. With optical fiber, images cannot be transmitted as they are. Light waveguide path materials are those that accumulate roles of mirror and lens in a sheet of the material and construct a system which is strong in vibration, as optical parts connecting among materials for two dimensional data processing. 273 refs., 107 figs., 17 tabs.

    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)

    Firstly, an indication is made that most functions of an in-vehicle navigation system relate to the use of a road map data, and on the conditions the map database therefor should provide depending on the intended usage. Secondly, an explanation is given on the self-contained navigation system and a combination of the self-contained navigation system and wireless navigation system to detect a position of the vehicle. In regaeds to the former, a method is introduced that the present location is estimated by means of adding the displacement vector per unit time derived from azimuth and distance sensors, and the error therefrom is cancelled by comparing it with the road map data. In regards to the latter, the wireless navigation aided by an orbital satellite and the proximity wireless navigation are described. Thirdly, functions to indicate the vehicle location on a map, retrieve and set the destination, and retrieve and indicate the facility guidance information are explained. Fourthly, a description is given on an automotive traffic information communicating system which indicates traffic information on a map and guide a recommended course to the destination. 10 refs., 7 figs., 2 tabs.

    In wind resistance design of long span bridge, as the vibration found in long span bridges is very complicated, the estimation with high precision of the unsteady aerodynamic force acting on structures in complicated motion becomes more and more important. In this paper, as a problem to directly identify the parameter by using the observation hysteresis response obtained from wind tunnel test, the problems existing in combining the system identification into unsteady aerodynamic force estimation were indicated. Then, newly developed flexible method in extension relating to two dimensional aerodynamic force measurement concerning composite flutter was proposed. Using the wind tunnel test response observation data obtained from two dimensional rigid model, and from the estimated results of unsteady aerodynamic force, it is possible to obtain stable results in the relationship among the plural eigenvalues displaying identified vibration frequency and attenuation rate with the reduced wind velocity. As a new unsteady aerodynamic force measuring method, the method proposed by this study is considered to be very useful. 6 refs., 5 figs., 1 tab.

    Recycling resources is gaining importance increasingly to correspond to global environmental problems. In urban areas, in particular, it is important to efficiently recover and recycle used large-size consumer products, e.g., home electric appliances and automobiles, which are discharged in large quantities. This study proposes a shared product life-cycle total information system, based on recognition that material recycling systems, encompassing stock materials, product production, consumption, and disposal and recycling of wastes, are essential. This system corresponds a material to information, in an attempt to realize more efficient recycling of products. The study for this fiscal year was focused on use of information modules attached to products and their members, product recycling systems using these modules, necessity for and problems involved in thermal recycle systems, problems involved in recycling home electric appliances and extraction of the data for their recycling, and material recycling process systems for home electric appliances and automobiles.

    Currently in the major power transmission line, a composite fiber optic overhead ground wire (OPGW) is installed, and it is being made the best use as an information transmission line. When the various maintenance informations on the transmission lines can be collected and transmitted by utilizing this OPGW, there will be the benefits that an effective system for the maintenance work of the transmission lines can be constructed, the informations, which could not be obtained by a conventional patrol and tour inspection so far, could be all the time acquired highly accurately and more rapidly. In this report by considering a use of the radio transmission together with OPGW transmission, in order to solve the constraints on an information transmission in a power transmission line maintenance system by utilizing OPGW, the concrete radio transmission systems were proposed about each of interpolation method of the sensor signal transmission method and the OPGW data transmission system. Especially as for the sensor signal system, it was shown that, as a result of the quantitative investigation of a transmission efficiency taking account of the hidden terminal problems, an interpolating data transmission system through a low-power radio combined the slotted transmission timing with the carrier sensed multiple access (CSMA) system was superior. 8 refs., 7 figs., 6 tabs.

    Composite fiber-optic overhead ground wires (OPGWs) installed to the major power transmission lines are applied as the information transmission routs with large capacity. An effective system for the power line maintenance operation is able to be set up by using said OPGWs to collect and transmit various kinds of maintenance information on the power lines. However, since it is necessary for the whole equipment to meet the highest transmitting speed required by the system if a single transmission method is applied throughout the power lines for transmitting the maintenance information, the system loses its economy as a whole. In this paper, for the purpose of transmitting effectively the various maintenance information in power line maintenance information system using OPGWs, and considering the required transmission period as well as the types of the data occurrence, an optic fiber transmission system constituted hierarchically and composed of high-speed trunk line and low-speed local line is suggested. Especially, regarding the low-speed local lines, random transmission method shows the superior properties in the transmission efficiency and low power-consumption compared with the cyclic transmission method. 9 refs., 9 figs., 4 tabs.

    A double layer micro capsule composed of nylon and polystyrene has been prepared by a combined process of interracial polymerization and solvent evaporation. The release rate of sodium ions as a core material was investigated with the microcapsules coated by a synthesized lipid. The permeation rate drastically changed corresponding to the phase transition temperature of the bilayer membranes composed of the lipid. The permeability of the core material above the phase transition temperature was 1-order of magnitude higher than that below the temperature. A functional microcapsule in which a core material is controlled by a membrane structure can be prepared by coating the micro capsule with a synthesized lipid. 5 refs., 3 figs.

    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.

    Research was made on electronic NEDO research reports corresponding to the recent extending trend of Internet. The logical structure and electronic format of NEDO research reports as document were first studied considering document disclosure and reuse of technical information. HTML as electronic format for Internet is unfortunately insufficient to describe the logical structure of NEDO research reports because of HTML's restricted description. Thus, XML which is being watched because of its possible definition of original tags was studied in place of HTML. As a result, because at present preparation of standards on XML and a compatibility for implementation of standards are insufficient, it was concluded that construction of the electronic document system for NEDO research reports is still too early. However, since adoption of XML as document format is important from the viewpoint of a property succession on Internet, preparation of the XML format file of NEDO research reports is essential.

    Study on analogue integrated circuit technique borne by needs of recent multi-media communication is advancing to a direction intending to decide problem by a construction technique for a system of transmitter and receiver rather than individual circuit. As for a process technique of the circuit integration, a minute CMOS (Complementary Metal Oxide Semiconductor) with 0.5{mu}m or 0.35 {mu}m thick silicon is occupying at its main part, from bipolar or a little older GaAs. As it is said that the 21st Century is an age of optonics, since success in oscillation of the ruby laser, advancement of laser technique and its application technique is miracle. Advancement of medical bioengineering is also miracle, biological information processing and visualization of biological information in artificial internal organs and biological measurement are also advanced. Development of communication technique in optical fiber got into its stride since 1970. Now, the optical fiber cable was expanded to 13 times for these ten years, and reached 79,000 km in 1996. Owing to the development of network computing technique, environment of computer changed dramatically. 6 figs.

    This paper describes the communication information security technology. Encoding is a generic term for the method to make data unreadable to persons other than those authorized. Of the encoding algorithms in the Internet, the common key system uses the same key for both of encoding and decoding, where the same key is shared and maintained confidentially by a transmitter and a receiver. The open key system uses two keys made in two pairs called an open key and a confidential key. Encoding is performed by using the open key possessed by a transmitter and decoding is possible only by the counterpart possessing the confidential key. Good points of both systems are combined and mounted in actual systems. This paper also describes a verification technology as a mechanism to prevent unauthorized data alteration. In security protocols, security function (encoding) is added to a communication protocol. The virtual private network has come recently to the practical application phase to realize such an environment that a dedicated line is installed virtually on an Internet line by applying the encoding technology, making it possible to structure a low-cost and safe communication routes.

The questionnaire survey selected 879 business entities involved in manufacture and sale of the welfare goods. The effective reply recovery rate was 19.3%. The questions had the data contents required by products classified into body dimensions, motion capability, sensory functions, and work capability, asking to state data contents required for each item, reasons for the needs, and data sources. The data source currently utilized reveals that most of the replied enterprises utilize data derived from the company's own measurements, developments and experiences. The contents thereof indicate that the data are too old, the data contents do not match the current situation, and no required data are available. In designing, developing and fitting the welfare goods, the required data may not necessarily be obtained, whereas improvement in the database is strongly desired. (NEDO)

    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 R and D program is aimed at advancing techniques for creation of optically functional materials for information communications through research and development of the processing techniques for optically reactive, multi-functional waveguides, in which three-dimensional optical writing is used, and materials for optical devices. For creation of novel, light-responding materials, possibility of formation of micro regions of different refractive index is confirmed, with NaO-TeO{sub 2}-based glass (tellurite-based glass doped with cobalt oxide to enhance light absorbing efficiency) as the standard composition. For preparation of planar Bragg diffraction lattices composed of a transparent, electroconductive material, these lattices are successfully developed by a combination of optical crystallization of amorphous ITO with the aid of eximer laser, irradiation of the laser beams via a phase mask and chemical etching. For development of light-storing materials, green, long after-glow fluorescence is successfully realized by combining CaO-Al{sub 2}O{sub 3}-based glass, molten and reduced in a carbon crucible, with Tb{sub 3}+.

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

    The renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure. In order to clarify the signaling mechanism mediated by angiotensin 2 receptor, Gq-protein binding amino acid residues of this receptor were clarified by site-directed mutagenesis study. Amino acid residues in the carboxyl tail region were changed by alanines, individually. These mutated receptors were expressed stably in CHO cells, and GTP effect and second messenger molecules were determined, and three residues (Y 312, F313 and L 314) in this region were determined to be concerned for the binding of Gq protein. The other signaling systems, Gi, MAP kinase, JAK-STAT mediated, were reported to be concerned for this receptor. Novel drags for high blood pressure therapy would be explored by clarifying these signaling mechanisms. (author)

    In recent years, exploitation of natural energy by saving fossil energy is being reconsidered. One of the expected sources of natural energy for the future is wind energy, which has been actively studied as a substitute source of energy for the world. However, the wind energy is influenced by geographic and weather conditions. So that the generating power varies with time. Therefore, in order to make the windmill generator system to extract available maximum power from wind energy. This paper proposes a tracking control method of maximum power operating point using the recursively least square method with forgetting factor. The proposed method is simple since it identifies the system parameters and controls the actual rotor speed by means of a PI controller. The system parameters are identified by using the information for generating power and windmill speed. We verify the effectiveness of the proposed control method with numerical simulations and experimental. 11 refs., 12 figs., 3 tabs.

    Technical trends were surveyed concerning the recovery and the use as fuel of low-concentration methane gas or the like contained in the air ventilated out of coal mines. Methane gas recovery technologies include high-temperature incinerators and catalytic incinerators designed to collect heat, method of conversion of methane to CO2 using microbes named methanotrophs, and adsorption methods using activated charcoal, zeolite, or the like. Among technologies that have reached a practical level in the utilization of mine methane gas, there are the temperature regenerative flow-reversal reactor (TFRR) and the catalytic flow-reversal reactor (CFRR) utilizing high-temperature oxidation reaction. TFRR has been reported effective by MEGTEC System after a 6-month operational test of a 3.0m{sup 3}/s plant at a British coal mine. Test and research are over with CFRR, which is now ready for a commercial scale verification test. Recovery by adsorption, though worth further research efforts, is economically away from commercialization at the present stage, and wants more studies of adsorbents, etc. (NEDO)

    A survey was conducted to construct a simulation technique for predicting changes in the behavior of gas to accompany digging in Australian coal mines. The survey activities were conducted in the mining area of the Wambo colliery in the Hunter valley, New South Wales, which involved the acquisition of geotechnological data including the amount of coal reserves and the amount of methane gas held in the coal seams, drilling of 19 test bores (with cores sampled from some of them), geophysical logging of the test bores, seismic exploration, analysis of the sampled cores, rock tests, modelling of the geological structure, testing of gas from the coal seams, modelling of the state of existence of the gas, and so forth. It was found that the amount of gas held in the coal seams at levels 200m or deeper was larger than 9m{sup 3}/t. Existing software programs were examined as to whether they could be used for the preparation of a gas behavior simulation program, and it was found that none of them was capable of helping the simultaneous simulation of rock deformation due to drilling and the resultant change in multi-phase gas behavior. The conclusion was that it was necessary to newly develop a comprehensive simulation software program. (NEDO)

    The purpose of this project is to reduce environmental load by investigating the recovery/utilization technologies of mine methane gas, to build predictive simulation for the behavioral change in methane gas that is incidental to underground mining, and to reflect the simulation on the optimum mining plan. Performed in the survey this year were the information collection/analysis of the coal and gas resources, exploratory boring for the purpose of grasping the geology, coal bed and gas abundance in the selected survey sites, measurement of coal bed gas reservoir, and the survey of geotechnological features. The operations were as follows; collection of existing geological data and selection of exploratory boring sites for Arrowfield layers and Bowfield layers in the Hunter Valley region. The coal bed gas reservoir and the composition of the coal cores obtained in eight borings this year provided precious gas data along with the survey results performed in the subject sites in the past. In particular, significant data necessary for depth coal development were also obtained in the surrounding mines including the subject survey sites. It was confirmed that the gas reservoir in the coal bed was 8 m{sup 3}/t to 9 m{sup 3}/t on the average. (NEDO)

    For standardization under information security evaluation criteria, an evaluating technique CEM (Common Methodology for Information Technology Security Evaluation) was constructed as ISI/IEC15408. The method, however, is abstract in content and the evaluation work thereunder requires much time and accompanies economic difficulties. In dealing with the situation, investigations were conducted into security evaluation related techniques and manufacturing/quality control techniques in use at information processing product developing sites, and a CEM technique is materialized. Using the proposed technique, developers themselves can evaluate security in the development process and workloads imposed on evaluating organizations may be reduced because evidential items necessary for 3rd party evaluation may be gathered. Since the developed technique is verified by an official evaluating organization, it is expected to be an effective techniques not contradicting existing operating techniques. It may be also said that this technique is a method whereby developers will collect evidential items necessary for their development efforts. The result will be presented in the form of a proposal for an evaluating techniques standard for ISO/IEC JTC1 SC27. (NEDO)

    Improved accuracy and efficiency of magnetism analysis has advanced magnetic exploitation from a mere tool for exploitation of iron ore deposits to a general tool for analyzing geological structures. Magnetism in a bed rock and presence of a rock of high magnetism penetrating a bed rock cause magnetic anomaly, and it is possible to grasp morphology of a sedimentary basin by analyzing its magnetic anomaly observed, for exploitation of oil and natural gas. Magnitude of anomaly must be handled as vector sum of induction and residual magnetization. However, it is sometimes erroneously explained by use of a model which neglects the effect of residual magnetization. This paper reviews the basic aspects of anomaly analysis, and describes an example in which seismic exploitation based on the reflection method, gravity anomaly and magnetism anomaly are considered to explain geological structures, taking, as a case study, geomagnetism anomaly observed off Sanriku. The rock-magnetical geological structures are clarified by a variety of tests, including those for demagnetization of the samples by stepwise applied alternating current and heat. 9 refs., 8 figs.

    Three types of basic network configurations, i.e., mesh type, star type, and hierarchical type, were evaluated from performance at fault and transmission path capacity. Based on the results, proper physical network configuration was clarified in response to scale of the network and decentralized/centralized information flow. A program was developed, by which physical network configuration satisfying constraints concerning paths and links can be determined. By changing a ratio of decentralized/centralized information amounts, switching performance at fault and required transmission path capacity of an office-branch scale network configuration were evaluated using simulation. When the decentralized information amount was the same as or more than the centralized one, the mesh type provided an advantage from the viewpoint of switching performance and transmission path capacity. When the centralized information amount was large, the hierarchical type provided an advantage. The star type provided an economical advantage from the viewpoint of required links. However, its switching performance and required capacity were inferior to those of other networks. Especially, when the decentralized information amount was large, the difference was remarkable. 10 refs., 14 figs., 3 tabs.

    Background Dengue control and prevention rely heavily on insecticide-based interventions. However, insecticide resistance in the dengue vector Aedes aegypti, threatens the continued effectiveness of these tools. The molecular basis of the resistance remains uncharacterised in many endemic countries including Malaysia, preventing the design of evidence-based resistance management. Here, we investigated the underlying molecular basis of multiple insecticide resistance in Ae. aegypti populations across Malaysia detecting the major genes driving the metabolic resistance. Methodology/Principal Findings Genome-wide microarray-based transcription analysis was carried out to detect the genes associated with metabolic resistance in these populations. Comparisons of the susceptible New Orleans strain to three non-exposed multiple insecticide resistant field strains; Penang, Kuala Lumpur and Kota Bharu detected 2605, 1480 and 425 differentially expressed transcripts respectively (fold-change>2 and p-value ≤ 0.05). 204 genes were commonly over-expressed with monooxygenase P450 genes (CYP9J27, CYP6CB1, CYP9J26 and CYP9M4) consistently the most up-regulated detoxification genes in all populations, indicating that they possibly play an important role in the resistance. In addition, glutathione S-transferases, carboxylesterases and other gene families commonly associated with insecticide resistance were also over-expressed. Gene Ontology (GO) enrichment analysis indicated an over-representation of GO terms linked to resistance such as monooxygenases, carboxylesterases, glutathione S-transferases and heme-binding. Polymorphism analysis of CYP9J27 sequences revealed a high level of polymorphism (except in Joho Bharu), suggesting a limited directional selection on this gene. In silico analysis of CYP9J27 activity through modelling and docking simulations suggested that this gene is involved in the multiple resistance in Malaysian populations as it is predicted to metabolise
