    To know the trend of measures taken for global warming, conducted were overseas surveys, participation in academic society meetings, and literature surveys. The phaseout time of all ozone depleting substances responsible for the ozonospherial destruction was determined for both developed and developing countries in the 7th Meeting of countries which concluded the Montreal Protocol. As information on measures for protecting the ozonosphere, introduced was activities under United Nations Environment Programme (UNEP). New fluorine containing ethers were introduced as cleaning solvent which causes no ozonospherial destruction and is low in global warming index. Toxicity data were obtained on HFC-236ea and HFC-236fa which are promising substitutes in HCFC foaming and refrigerant fields. The paper introduced an outline of the 1st Meeting of countries which concluded the Framework Convention on Climate Change held in 1995. According to the report on the National Institute of Public Health and Environmental Protection of the Netherlands, the amount of emission of fluorine containing greenhouse effect gas (in CO2 conversion) reached 8-14% of all the amount of greenhouse effect gas emitted in 1990 unless the control is reinforced. An outline of the TEWI-3 project was introduced which is useful for comparing effects of substitution technologies on global warming. 14 refs., 11 figs., 29 tabs.

    This is a report on the global warming issue made by the Institute of Energy Economics entrusted with the survey by NEDO. Written below are titles of the chapters in the report: 1. Outline of global warming problems and developments of international conferences. 2. Factor analysis of past CO{sub 2} emissions. 3. Measures to limit global warming. 4. Limitation measures for global warming and prospects for CO{sub 2} emissions. Analyses are made by country, by region or globally. For example, in order to establish measures to solve the global warming problem as an international issue, it is most important to establish the target criteria to control emission of greenhouse gases like CO{sub 2}. Namely, most important is to determine the criteria and partial charge of each country. These will exert a large effect on each economic activity. There are big differences among countries in the gas emission up to the present from the past. Effects of the gas emission are also different among countries. Moreover, countries are different in their development stages. All these differences are an important subject in judging international fairness. 91 refs., 91 tabs.

    A large scale earthquake was frequently occurred in 1993, 94 causing many damages. Based on the consideration that the telecommunication network has an important role in such the disasters, various measures have been taken from the past. The basic ideas in taking measures for the telecommunication network against disasters are; (1) `Upgrading of system reliability` which includes the strengthening of equipment itself and the redundant composition of network, (2) `Prevention of communication stoppage` which enables to allow communication even when the system is damaged, and (3) `Early reactivation of telecommunication service` when the system is physically damaged. Some examples proved that these approaches taken from the past are effective in the recent seismic disaster. 5 figs., 1 tab.

    As for, countermeasures for chemical contaminants in a cleanroom air, the technical development has progressed earnestly since T top phenomenon of photo-amplified resist with basic gas due to atmosphere was pointed out in 1991 by MacDonald. Airborne-Molecular-Contamination (AMC) is classified into acids, bases, condensables, and dopants. According to SEMATECH no 95052812A-TR, condensable are defined as silicones or hydrocarbons with a boiling point greater than or equal to 150 degC. Water-soluble gaseous contaminants in outdoor air coming into cleanrooms are removed with a water spray equipment. AMC originated from circulating air in cleanrooms are prevented using various chemical filters. Conventional chemical filters made of activated charcoal, however, have several defects. Ceramic chemical filters developed by the authors are nonflammable, and consist of inorganic materials without any volatile organic matters and without alkaline metal and so on, and they have high removal efficiencies of condensable. 15 refs., 12 figs., 3 tabs.

    Introduced herein is a summary of the technological research report about functionally gradient materials that was presented by Information Center of Exploration of Petroleum in fiscal 1994. The functionally gradient material was realized in the 1980s thanks to more than 30 technologies industrial or government sector bodies interested in science and technology, which effort was related to Japan`s recoverable manned spaceplane program. The material, equipped with the high thermal conductivity and mechanical strength required of a material to cover the spaceplane body, was born out of a innovative idea in which the constitution, etc., of two different materials should continuously change for the elimination of any boundary between the two now that a direct bondage of a metal and ceramics would after all experience separation or cracking. The new idea enabled a plurality of desired functions to be freely distributed within the material, creating hopes in various fields. It has been found that probabilities are high that the functionally gradient material will improve at a surprising rate the conversion rate in utilizing thermoelectricity, photoelectricity, or nuclear energy. In the oil industry, studies are under way to use the new material in petroleum exploration, etc., that have to be undertaken under severe conditions. 1 ref., 2 figs., 2 tabs.

    This paper reviews essential problems of water environment and trends of solution technologies related to water quality problems promoted by Fuji Electric. They have developed a water quality safety monitor for high-sensitivity monitoring of river water and lake water, and a water quality control system for supporting river managers during water quality accidents. For the water quality safety monitor, nitrification bacteria sensitive to toxicants are fixed as bacterial membrane, and it is attached on the dissolved oxygen electrode. Toxicants mixed in the river water can be detected by determining the activity of nitrification bacteria from the change of dissolved oxygen consumption. This provides ten times of detecting sensibility compared with fish. A coagulation sensor has been also developed for the low turbidity operation during water purifying process and the optimal injection of coagulants. High-performance ozonizers have been developed for advanced treatment of purified water. Using this, nasty smell and precursors of trihalomethane in drinking water can be strongly decomposed. For the field of sewage water, a biosensor has been developed. It takes only 20 minutes to measure BOD, which took 5 days previously. For the treatment technology, a two-tank type intermittent aeration activated sludge process has been completed, which provides a remarkable removing effect of nitrogen and phosphorus in sewage water. 18 refs., 2 figs.

    The size and complexity of electric power systems has been increasing as a result of the construction of new generators, subsections, and lines to meet the steady growth in load demand. Electricity is an essential form of energy that supports society, and utilities are required to ensure high-quality electricity supplies without interruption. However, faults such as lightning may cause loss of synchronism among generators, leading to a blackout. In order to prevent such an expansion of loss of synchronism, many systems based on the latest technologies have been developed and applied. This paper outlines various types of disturbances that occur in electric power systems, and describes approaches and systems for preventing blackouts. In addition, a description is given of new functions that will be required in the near future in order to maintain the stability of electric power networks. 1 fig., 4 tabs.

    To the aeroengine, a requirement for an improvement of the fuel consumption ratio from a viewpoint of the energy saving and for a reduction of the harmful exhaust materials from a viewpoint of environmental protection is being increasingly elevated. In order to improve a fuel consumption ratio of engine, making it a higher temperature and pressure is attempted for raising a engine cycle efficiency, and moreover there is a trend to elevate an inlet pressure and temperature of the combustor as for a combustor, and consequently an outlet temperature of the combustor becomes higher. Therefore to the combustor, a durability elongation of the liner and fuel injection valve, as well as a correspondence to a range expansion of a fuel-air ratio of the combustor are demanded. As the harmful exhaust materials, there are unburned hydrocarbon (UHC), carbon monoxides (CO), nitrogen oxides (NOx), and smoke. A reduction of NOx is most strongly requested at present. In addition to these requests on the combustor, making a study and development of the combustor more efficient is being demanded. For this purpose a numerical analysis is utilized by adapting the various purposes. As the recent utilization methods, the prediction examples of exhaust gas quantity are frequent. 14 refs., 12 figs., 1 tab.

    This paper introduces a summary of the survey made on the Swedish policies on alternative energies. The country has a characteristic that the alternative energy policies have a great importance for each political party as its reigning strategy. The largest weight for the alternative energies is placed on bioenergies. Sweden has been already depending on bioenergies at 15% of the country[prime]s total energy supply. Nearly half amount of the budget in the new five-year alternative energy plan approved in 1991 is bioenergy related. The budget of 3.76 billion kronor can be broken down into 1 billion kronor for effective energy utilization, 1.92 billion kronor for bio-fuel utilization, and 800 million kronor for bio-fuel utilizing plants. The bio-fuel utilizing plants include improved CFB utilizing steam cycle power generation, gasified compound cycle power generation, a bio-fuel/natural gas compounding plan, and a bio-fuel/caustics recovery boiler compounding plan, each having merits and demerits. Thirty-five wind power generating plants are in operation producing a total power of about 10,000 MWh in 1990. 3 figs., 4 tabs.

    This paper describes the recent energy policy in the EU region. In 1992, the EU Commission employed a strategy for realizing a single energy market. In 1994, the Council of Ministers adopted directives for liberating the permission condition of survey, exploration and development of hydrocarbons. The EU Commission employed a three stage approach for liberating the gas and electric power market. The Transit and Pricing Directives in the first stage consists of three directives of electric power transit, gas transit and pricing transparency. In the second stage, Third-Party Access (TPA) system is to be introduced. An analysis in the third stage depends on the results in the second stage. Are also described the CO2 and energy tax, emission of greenhouse gases, and integrated pollution prevention and control. Furthermore, the energy efficiency and the Trans-European Networks are described. Finally, are referred the regulations which control the activities of energy companies, and the national assistance policies in the energy division.

    The wear troubles of the water-supplying pump as well as water-supplying control valve due to the blocking-up of the strainer caused by the abnormal breeding of iron bacteria in ion-exchanged water have been occurring frequently since several years before in Oita Manufactory of Nippon Steel Corporation. The strainer provided in front of the pumps for supplying the water to each users are blocked up by the iron bacteria bred abnormally in the tanks of ion-exchanged water. Consequently, the cavitation phenomenon of water-supplying pump happens and the inside wear occurs. It is revealed by the results of the examination on the prevention countermeasure for breeding of iron bacteria carried out by the present authors that the destruction and the extinction of the cells are brought about by the concentrated electrification of the iron bacteria due to the electrification in the ion-exchanged water. In this paper, the principles, progress of study and development, the results of the practical tests in respect of prevention countermeasure for breeding of iron bacteria in ion-exchanged water by turning on electricity are described. The conventional means of frequency transformation are used in the experiment, and the betterment such as the increase of capacity of condenser is added because of the high electricity-resistance of ion-exchanged water. 13 figs., 1 tab.

    Fundamental experiments were conducted on active noise control as sound insulation fence. This control method generates a sound source with the same amplitude and opposite phase as noise, and reduces noise through the interference of acoustic wave from the source. However, this method has too many problems with the three-dimensional sound field to be actually exploited in this environment. The following experiments were conducted to apply the active noise control to the sound insulation fence: one method of installing a geometric path along the inner side of the sound insulation fence used the acoustic delay process generated on the source side to attenuate the sound pressure level on top of the fence through interference of routing difference sound. The other method used an additional sound source attached to the bottom of the geometric path above to obtain a higher attenuation than using the simple sound insulation fence. At the second step, the active control duct model was used for the test. Then, the three-dimensional model test was conducted for active control of the sound insulation fence. The results of these fundamental experiments have indicated that each method can reduce the relative sound pressure level and the active noise control system using the acoustic phase difference can effectively reduce noise with dominant components in a low frequency band. There are still several problems with the three-dimensional mock-up model. 4 refs., 18 figs., 2 tabs.

    Some cases of poisoning by chemical substances are taken up, and counterplans are discussed. This report centers about the neurotoxic gas sarin incidents dealing with them as examples of acute poisoning caused by chemical substances. The important difference in terms of chemical structure between a neurotoxic gas and organo-phosphoric pesticide is that in the former phosphorus is directly bonded with carbon or halogen while, in the latter, bondage is represented by P-O-C, P-S-C, and the like, so bonded as to form the phosphoric acid, thiophosphoric acid, or dithiophosphoric acid. The result of the difference in chemical structure is that the neurotoxic gas easily gains access to the target enzyme and remains stable after bonding therewith while the organo-phosphoric pesticide is easily hydrolyzed by enzymes other than the target enzyme. Poisoning by neurotoxic gas or organo-phosphoric pesticide is clinically treated by the administration of atropine and 2-pyridine aldoxime methiodide which is an antidote. It is mandatory to let people clearly know beforehand the methods of analysis of chemical substances and their toxicity and to establish beforehand how to first-aid the victims and what emergency treatment can be executed. 11 refs., 2 figs., 2 tabs.

    Full Text Available The objective of this work was to determine the inheritance of the long juvenile period trait in natural variants of the Doko, BR 9 (Savana, Davis, Embrapa 1 (IAS 5RC, and BR 16 soybean cultivars. Complete diallel crosses were made between the Doko and BR 16 cultivars and their variants. A 3:1 segregation ratio was observed in the F2 populations of the 'Doko' x Doko-18T, 'Doko' x Doko-Milionária, 'Davis' x São Carlos, and 'BR 9 (Savana' x MABR92-836 (Savanão crosses, indicating that the long juvenile period trait is controlled by a pair of recessive genes. The difference in late flowering between the Doko cultivar and both of its variants was caused by a recessive spontaneous mutation at the same genetic locus. However, the variants Doko-18T and Doko-Milionária are identical mutants that share a pair of genes that control the long juvenile period under short-day conditions. These mutants can be used in breeding programs to develop cultivars adapted to low-latitude tropical regions.

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

    Studies are made of optimum materials and methods for manufacturing low-carbon fuels for reduction in greenhouse gas emissions. When their thermal dynamic limits and the technological maturity are considered, it is inferred that no extensive improvement will be achieved by merely improving on the efficiency of the existing fuels. The use of various high-efficiency driving power sources utterly different in mechanism from the conventional ones, such as those for fuel cell-powered automobiles, and the promotion of the use of low-carbon fuels such as methanol and methane for all kinds of driving power sources including those for the said fuel cell-powered automobiles, will become necessary. The use will also be necessary of recyclable materials. The biomass resources, in particular, since they absorb CO2 gas in their growing process by virtue of photosynthesis, may be said to be free of CO2 gas emissions. They have their own problems, however, which involve the economy of energy consumed for their production, harvesting, transportation, and conversion into fuels. It is therefore required that their whole life cycle be studied before their greenhouse gas reduction effect may be correctly assessed. The quantities of resources available for the production of automotive low-carbon fuels, manufacturing technologies, etc., are first of all put in order for easy perusal. An effective way is assessed for the whole including the life cycle. (NEDO)

    Market and technology trends of seismic rubber bearings (SRB) after Hannshin-Awaji big earthquake are explained, and problems to overcome for spreading seismic isolation are considered with both aspects of technology and regulation. Since the big earthquake, the market of SRB for buildings has been rapidly activated, sale in 1997 being predicated to amount twice as much that in 1996. For ordinary seismic buildings, their seismic designing is conducted under assumption that intrinsic frequency of earthquake wave should be 2 seconds at longest. It is preferable to assume longer frequency for larger seismic effect. However, the longer the frequency is assumed, the larger the deformation of SRB should occur on earthquake, resulting in being liable to buckle or rupture. Thus, SRB is tend to be larger and replacement of SRB/damper integral type SRB to separate type wherein they are set separately for more damping, has been proceeding. Whereas bearing load of SRB to vertical direction has be presumed to be 50{approx}80 kg/cm {sup 2}, use under much higher face pressure is requested lately. However, the increase in load induces increase in compression creep, promoting material deterioration. This problem is discussed in detail with material strength data. 6 refs., 17 figs.

    This paper introduces the recent crude oil and natural gas trends in Algeria and Libya out of the 6 African countries which account for more than 90% of crude and natural gas produced in the African continent. Algeria is now under severe economic situations, with deficits totalling 26 billion dollars. She depends on crude and natural gas for 95% of her foreign-exchange earnings. A number of foreign firms are now developing the oil and gas fields under dynamic political situations, with the Islamic fundamentalism radicals gaining power. She is now planning to expand the exportation of natural gas to European countries, produces 1.15 M B/D of oil (1994), having an R/P ratio of 34 years and refining capacity of 470 K B/D, and has the gas reserves of 3.7 trillion m{sup 3}, selling a total quantity of 53.9 billion m{sup 3}/y (1993). The UN`s sanctions on Libya for its acts of terrorism, such as blasting of a PamAm plane, have not had a fatal wound influenced on the Libyan economy. Oil exportation of 1.3 million B/D, accounting for 95% of her foreign- exchange earnings, gives the highest GNP per capita in Africa. Her oil reserves total 22.8 billion B (R/P ratio: 46 years). 6 figs., 15 tabs.

    Creation of new biocatalysts was surveyed to convert chemical reactions into environment-friendly processes. Biocatalysts are characterized by their high catalytic activity, uniqueness of reactions, and non-pollution under mild conditions. Stability is required for them, such as heat resistance, solvent resistance, acid resistance and alkali resistance, under severe conditions. For the development of new biocatalysts, it is necessary to multiply utilize the techniques containing enzymes, ribozymes, mold synthetic polymers, chemical modification, and non-natural proteins. Natural enzymes have been conventionally improved through the search, imitation and modification. Hereafter, new biocatalysts with functions required for the reactions should be created by integrating information regarding functions, structures and activation of these enzymes. It is indispensable to cooperate closely with supporting techniques, such as gene engineering, organic synthesis, biophysics and computer chemistry. 35 refs., 26 figs., 1 tab.

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

    A study was made on the LP gas supply/demand in Asia including an outlook for 2000. Eleven countries in Asia including NIES countries, ASEAN countries, China and India have been continuing their rapid growth of economy and have rapidly been increasing their energy consumption. There, LP gas spreads as a home use fuel, and countries excluding some LP gas producing countries depend considerably upon the import from the Middle East. The LP gas consumption quantity is steadily increasing in China and India having huge population, etc., and dependence of LP gas is increasing upon LP gas producing countries of the Middle East. Nevertheless, in the Middle East, the domestic consumption of LP gas, mostly butane, is increasing. Namely, butane is used as raw material of MTBE, and LP gas as that of petroleum chemicals. The Middle East has a lot of plant projects of a sizable size in the future, which predicts that LP gas export from LP gas producing countries of the Middle East is decreasing. 2 refs., 62 figs., 57 tabs.

    This paper describes the trends and future prospects of petroleum production in the newly rising oil producing countries: Syria, Oman, and Yemen. Syria, who has been depending on petroleum for its domestic energy demand, now plans to lay stress on natural gas development and utilization. Although the country is blessed with petroleum and gas resources, the energy demand and supply is in off-balance. Discussions on realistic measures aimed at complete utilization of energy resources are required to realize good demand and supply balance and expansion in petroleum export. Oman is a petroleum dependent country whose national revenue is accounted for by earning from petroleum at about 80%. If the nation succeeds in promoting natural gas introduction as a substitute energy, it may be able to suppress the growth of domestic petroleum demand, and export of more LNG may be expected as planned. Yemen needs to expand petroleum export to obtain foreign currencies required for its economic reconstruction. Therefore, it plans to cope with the domestic energy demand increase by converting fuels into natural gas. An LNG export plan has been surfaced recently. 6 refs., 4 figs., 8 tabs.

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

    The advanced composites comprise of polymeric (PMC), metallic (MMC) and ceramic (CMC) types. Some PMCs have already been applied aeroplane parts, ships, sports goods, and others, and reduced their advancing images. The advanced composites given to much attention are the ones durable to more severe environments and using conditions proceeding space development and engines. Now, PMC is expected not only to show their higher specific strengths and modulus of elasticity but also to endure space environmental conditions. NMC and CMC are also expected from their excellent heat resistance point of view. In addition, thereafter, to develop the intermetallic compounds matrix composites, the gradient functional materials, and nano-composite materials, higher functionalities and more intelligences are desired to realize. And, their costs are also occupied at their important portion of their development, and also expected to produce their intelligent processing intending to their cost down. 18 refs., 6 figs., 6 tabs.

    Taking up smelting processes incorporated in the currently used recycling systems that handle Fe, Al and Cu scraps which are much recycled as metallic resources, considerations were given on the physical chemistry of the processes. In considering wastes and scraps as resources, it is necessary to recognize that the object metals are high in grades, but unstable quantitatively and they contain many kinds of elements (impurity elements) to be treated. As a method to remove copper from solid Fe scraps, the separation method utilizing the melting point difference is simple as a process, and is worth discussing for a practical use. However, a method to remove copper from alloyed iron melt and steel melt is difficult thermodynamically. Enumerating and discussing the problems in refining Al and Cu scraps revealed that there are a number of points insoluble by the currently available refining technologies, and concluded that superior refining processes must be developed, and the recycling problems must be considered including as far as the recovery systems. 66 refs., 11 figs., 9 tabs.

    Presently used cleaning process of silicone wafer is based on the modification of so called RCA method from the knowhow point of view, presented by W.Kern and others 25 years ago. On the other hand, with the progress of development of element for next generation, it was already clarified to be required on the process, demanded for high degree control of silicone surface. When considered the practical measure for this, there is a movement towards the establishment of new silicone wafer cleaning concept for new generation instead of making difficult process by precise RCA cleaning. One of the new proposed method is IMEC cleaning. Further, in Tohoku University, new cleaning process, alternative to RCA method is proposed, in which treatment of all chemicals is carried out at room temperature, types of chemicals used for cleaning are limited to minimum and also, concentration of these chemicals is kept as minimum as possible, amount of used superpure wafer is saved by effective recycling and reutilization of spent chemicals. With these tecnologies, there has appeared the sign for new development for cleaning technology. 36 refs., 28 figs., 6 tabs.

The indoor concentration of chemical substances shows a positive correlation with the amount of building and application materials emitting them. In general, it is highest at the completion, and decreases with time. The emission amount increases with temperature, and the indoor concentration decreases with the ventilation amount. These are greatly affected by the interior finish materials. Such chemical substances include formaldehyde, volatile organic compounds, termite-proofing agent, and plasticizer. The emission sources from life include furniture, curtains, carpets, insecticide and moth-proofing agent, wax, combustors, and smoking. For the construction, are significant the proper selection of materials such as adhesives and paints during design, and sufficient management during construction, sufficient curing and security of drying period, and ventilation before dwelling. For the bake-out method, room temperature is elevated, the emission is accelerated, and ventilation is conducted before dwelling. However, a part of this method has not been verified yet. The removal methods and decomposition methods are sometimes employed. 21 refs., 5 figs., 4 tabs.

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

    For the advanced utilization of casting iron, temperature differential austempering and partial austempering with the gradient mechanical properties of ADI (austempered ductile iron) by local electric method were experimentally investigated. For the former, gradient mechanical properties are obtained by giving temperature difference to the material in the process of austempering of casting iron, to add the strength and toughness. For the latter, mechanical properties are controlled by repeating partial austempering with changing the isothermal transformation condition by means of local electric method, to obtain the strength characteristics with appropriate balance. As a result of the former experiment, function gradient materials could be obtained with continuously changing internal mechanical properties. The fabricated material provided different properties depending on the direction of load. Radial crushing strength constant of the ring material depended on the treatment temperature of inside surface of the specimen. Fatigue and yield strengths can be simultaneously improved. As a result of the latter experiment, it was found that the mechanical properties can be improved at arbitrary part by the partial austempering. 13 refs., 25 figs., 4 tabs.

    This paper explains quantitatively performance of heat storage tanks contributing largely to levelling power loads, and promoting and spreading more effective use of unutilized energies. A model case was used to compare differences in effectiveness of unutilized energy utilization with and without use of heat storage tanks. The heat demand used was a value in a day with a peak room cooling demand, and a heat supply system using water heat source heat pumps that utilize sewage treated water was used to manufacture cold water. As a result, the effective utilization rate of unutilized energy was increased to about 1.3 times when heat storage tanks were used. Effectiveness of a heat storage tank comes from its capability that excess amount of cold water manufactured during nighttime when heat demand falls by utilizing sewage treated water is stored in the heat storage tank, and the stored cold water can be supplied being mixed with cold water manufactured during daytime when heat demand rises sharply in daytime. Because sewage treated water has its annual temperature difference stabilized at about 10[degree]C, a heat pump utilizing the sewage treated water can reduce power required to produce heat of 1 Gcal by about 40% during room heating and about 15% during room cooling over the heating tower type heat pump. 8 figs., 1 tab.

    In recent years the blue-green algae has occurred tremendously in the lakes at every places in the world, and therefore it has become a social problem. Especially in Australia and New Zealand, the damages not only on the cattles and the wild animals, they have commenced to develop up to the health problems of the residents. By a progress of the study of the blue-green algae toxins, a structure and toxicity of many blue-green algae toxins have been made clear. The microcystin which it one of them, is a hepatic toxin produced by the microcystis, anabaena and oscillatoria. By the way, because it was made clear recently by a study done by the National Cancer Center that it had a carcinogenesis promotion action, its action has been paid attention over again. In the blue-green algae toxins, besides the microcystin it is made clear that there are the nervus toxins such as the anatoxin-a and anatoxin-a (s) produced by anabaena, the aphantoxin produced by aphanizomenon and so forth. In this paper, as for the toxicity manifestation mechanism of the microcystin which is thought to become a point at issue in Japan, an information up to date is introduced. 17 refs., 2 figs.

    Examples of breaking are introduced concerning the welding in vessels and marine structures, and its measures are discussed. Some examples in vessels are a brittle fracture of butt welding zone caused by a defective penetration in a 5,000 ton lumber carrier; a fatigue failure caused by the unevenness of joint of a transverse partition in a bulk freighter; a lamellar tear caused by a restraint imparting in the thickness direction of a panel point; and falling of a leg which was due to a fatigue fracture starting from the crack of a part influenced by welding heat and which caused overturn of a semisubmerged rig. The following are the preventive measures. A welding method and steels mutually matching need to be selected for securing tenacity in a heat-influenced part of a welded joint. Prevention of a lamellar tear requires a design of a proper welding bevel, employment of a low hydrogen type welding electrode and a composition, use of pre-heating and a block welding method. Prevention of a cold crack in welding importantly calls for a setting of a bead length so that the hardness of a heat-influenced part may be 400 Hr or less and also for preheating. 15 refs., 12 figs., 3 tabs.

    Discussions were given on measures to reduce N2O as part of the measures to prevent global warming. Nitrous oxide has a long atmospheric lifetime of 150 years, and its greenhouse warming potential will increase by 310 times that of CO2 after 100 years. It can also be a cause of ozone layer destruction. Nitrous oxide is estimated to have influence of about 10% as compared with CO2 even under the present conditions. Discharge of N2O from manufacturing process of adipic acid is aimed to be eliminated totally by 1998. Improvement in efficiency of combustion of fossil fuels and wastes serves most effectively to reduce not only N2O but also CO2. Nitrous oxide generated in sewage treatment as in sewage purifier may be reduced if the batch process is turned into a continuous process, but assistance from policy side would be required for wider adoption of the process conversion. No environmental regulations are applicable to N2O, whereas a problem is present that the number of system installation would not grow because of economic reasons even if the system is feasible technically. Another problem is that the N2O reducing technology is in trade-off relation with other warming gases such as NOx and methane. Comprehensive technological evaluations aimed at optimization must be moved forward in the future. 236 refs., 102 figs., 78 tabs.

    Emission amount of nitrous oxide (N2O) from anthropogenic sources is analyzed, and reduction effects by the abatement technologies are evaluated. The concentration of nitrous oxide in the atmosphere continues to increase and emissions from agricultural and ecosystem sources are drawing particular attention. For the emission of N2O in Japan, 8.28 Gg-N2O per year is emitted from fossil fuel combustion facilities, 6.95 from waste incineration facilities, 22.5 from transportation vehicles including automobiles, 26.7 from the chemical industry including establishments engaged in adipic acid production, 2.1 from sewage treatment facilities including septic tanks, 6.3 from farmland, and 7.1 from livestock excrement. For the N2O abatement technologies for different sources, fuel improvement, high temperature combustion, acceleration of reduction decomposition reaction, and development of catalysts are significant for the combustion technologies. In connection with N2O discharged in the process of adipic acid production, major businesses have internationally committed to up to 99% abatement of the N2O emissions by 1998. With regard to wastewater and sewage treatment facilities and septic tanks, improvement in COD/NO-N ratio, retention period, pH level, and reduction process is pointed out. 204 refs., 70 figs., 53 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.

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

    Japan National Oil Corporation`s survey for fiscal 1997 of deepsea mine exploration and exploitation in the world is described. The survey discloses that future potentials are high in the Mediterranean, Asia, and Oceania although the generally known main deepsea oil-producing zones of the world belong in the Atlantic, as exemplified by the western part of the North Sea. The level of oil exploitation in the ocean that has been 200m or shallower in the past is now advancing deeper toward levels lower than 1000m. As for pilot drilling, although a 2000m-deep level is regarded as the limit beyond which progress deeper would be difficult, yet drilling into a 3000m-deep level is now being planned. Among drilling contractors, reorganization is under way through merger and acquisition. Although the total number of rigs has reduced, demand for rigs turned strong in 1996, and the number of rigs is increasing rapidly through new construction or refurbishment. As for ocean development systems, various practical applications have added to the list of available systems. 3 figs., 6 tabs.

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

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

    This paper describes the introduction of high-speed man riding train at Ikeshima Coal Mine. The production area is below the sea bottom in the southern offshore of the Ikeshima Island. With increasing the depth of production faces, it is significant for the insurance of operation time to enhance the intensive and highly efficient transportation system and to reduce the transportation and movement time. A high-speed man riding train has been introduced as a transportation system for workers. It is operated in the base gallery at the -650 m level from No. 1 train stop to southern train stop with a distance of 5477 m. It is operated at the maximum speed of 50 km/h, and the single transportation time can be reduced from 18 to 12 minutes. Construction was started in 1995, and practical operation was started in November 1996. Various technical problems were solved concerning the high-speed operation, advanced management of tracks, and monitor and control of operation conditions and a signal system. This system was named as `Goddess-Jikai` which has been operated 19 times a day in the running interval with a return way of 11 km. It has been safely and comfortably operated in a total distance of 33700 km by the end of May 1997. Oscillation is measured by the continuous oscillation monitoring system, and track management is enhanced using a track inspection train. Future high-speed safe operation is expected. 6 figs., 6 tabs.

    Focusing on the present status and future of coal demand in Central/South American countries and the coal trade between Central/South American countries and the U.S., the paper described the present status and future of coal demand there and the effects on Japan. Export of Colombian coal will amount to approximately 30-35 million tons in 2000. Venezuelan coal 10-20 million tons. The U.S. imported good-quality general coal low in sulfur content, 3.08 tons from Columbia and 1.39 tons from Venezuela. Coal export from the U.S. to Central/South America was mostly of raw material coal, 5 million tons in 1993 and 5.39 million tons in 1994. General coal was 180,000 tons. The U.S. has no plans of increasing US coal export to Central/South America. But it is safely predicted that Columbia and Venezuela will increase coal export to Europe in the future. It will bring about decrease in export of US coal to Europe, which connects with increasing pressure for the coal trade amount of Japan. 21 figs., 47 tabs.

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

    The pilot phase of the activities implemented jointly (AIJ) was approved in 1995 in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change to reduce greenhouse gas emission. In order to promote the AIJ Japan program smoothly, some practical examples in every preceding country and the situations and demands of Asian countries were researched. It was confirmed that since larger cost-effectiveness is achieved just in countries lower in emission control cost, AIJ can enhance the cost-effectiveness and promote environmental technology transfer. Japanese government had studied establishment of the framework for AIJ, and decided the basic framework of the AIJ Japan program in 1995. The government also approved the evaluation guidelines of this program which include confirmed and considered matters necessary for government offices related to this program to evaluate and approve each project.

    For the natural environment preservation, effective utilization of resources, and maintenance of the ecosystem, an international cooperation model was proposed for the environmental harmony type green technosystem. A comprehensive evaluating analysis of a green forest resource, etc. as the global resource, and an intensive extraction of subjects and needs was made. The analysis was conducted of technical possibility and abstract business development effects toward the industrialization with high values added which is in harmony with the environment. As a case study, the Papua New Guinea area, Malaysia was selected and re-evaluated. For this typical tropical forest area, a new technical system was studied based on the natural environment, industry/economy, social/cultural assessment, etc., and a model for industrializing new international cooperation was proposed. For the model making for industrialization, various steps to be taken and conditions to be prepared were studied and arranged for the realization. Upon going ahead with the international technical cooperation, Japan, a large lumber consuming country, needs to always consider the fostering and effective use of lumber resource in particular. 27 refs., 28 figs., 30 tabs.

    Recently, many of the low temperature materials such as LNG and LPG used as an energy substitution for petroleum were stored in the reclaimed land of the sea side district, however, it is necessary for those storage methods to enlarge sites. Therefore, it was considered to directly store the low temperature materials in openings excavated in the rock mountains. However, countermeasures for leakage of liquid and cold gas from cracks in openings would be an important subject. In this study, as a countermeasure for leakage of liquid and cold gas in the case in which low temperature materials were stored in openings in the rock mountains, the lining of resin materials on the surface of openings was proposed. Characteristics of strength and deformation and values of the thermal physical properties for the resin materials at the low temperature were obtained by experiments. This material was compared with granite supposed as a parent rock, and the thermal property of the resin materials was understood. Next, an analysis was conducted in the case of using the resin materials as a lining, the behavior of the surrounding rocks of the openings and the stability of the lining were investigated. 17 refs., 25 figs., 2 tabs.

    Magnetic sensitivity can be limited by microtremor of magnetically shielded room (MSR) used for the measurements of extremely magnetic fields such as biomagnetic measurements as well as environmental magnetic noise at low frequencies caused by trains, motorcars traffics and elevators but each of which can be reduced by MSR. The relation between the vibration of MSR and magnetic noise, and the reduction method of the magnetic noise due to microtremor of MSR are discussed experimentally. The correlations were high between acceleration in horizontal direction of ceiling panel and magnetic signal in horizontal and vertical directions. The magnetic noises were almost proportional to the displacement on the ceiling panel of MSR. Further an active isolation system was installed as a base of MSR to reduce the microtremor of the MSR.

    This paper summarizes circumstances of a catalytic oxidation type deodorizing experiment and a demonstration test on exhaust gas discharged actually from a print shop. The catalytic oxidation method is a method to burn the odor constituents, which are ethyl acetate, isopropyl alcohol and toluene, at temperatures of 200 to 300 degC. Space velocity was used as a parameter, and two kinds of platinum systems and two kinds of manganese + copper systems were used as catalysts. Elucidation was made on the space velocity and removal efficiency, removal efficiency of each catalyst, unreacted decomposition originated constituents at low temperatures (150 to 180 degC), and efficiency of each catalyst to remove each constituent. The result revealed that nearly 100% removal is possible at a space velocity of 33000 hr {sup -1} when the platinum-based catalyst and the manganese + copper based catalyst (both in pellet form) are combined. It was also found that the combination is advantageous in terms of cost. A demonstration test was performed at a new factory. Under a condition of combination of the above catalysts at 1:1 ratio, the space velocity of 30000 hr {sup -1}, and gas temperature at catalyst layer inlet of 200 degC, the removal efficiency was 97.9% to 98.7%, which clears the exhaust regulation value specified by the Tokyo Metropolitan Government. Average concentration in the working environment was 120.9 ppm, which cleared the maximum permissible concentration. 7 refs., 7 figs., 3 tabs.

    This paper describes the state of discharge of organic solvents from a print shop and a deodorizing experiment using a deodorizing equipment of activated carbon adsorption type of a bench test scale. The subject existing print shop has a working space volume of 2000 m{sup 3} and total air exhaust volume of 32000 m{sup 3} per hour. The identified main solvents are ethyl acetate, isopropyl alcohol and toluene. Solvent exhaust concentration at a duct was more than two times greater than the exhaust regulation value. The experiment was performed by using an equipment having an adsorption tower filled with activated carbons of particle form and pellet form made from coconut shell respectively. The gas concentration at an inlet to the deodorizing equipment was 394 ppm as the total concentration, exceeding the exhaust regulation value of 200 ppm. It was verified that the activated adsorption process has high removal effect. The break-through time which expresses life of activated carbon was 38 hours for the particle-formed carbon and 29 hours for the pellet-formed carbon when the total outlet gas concentration was set to 10 ppm. If the adsorption continues after the break-through time has been reached, a displacement phenomenon (displacement among constituents due to selective adsorption) can occur. The required length of the adsorption belt was derived. It was verified that the activated carbons can be regenerated and re-used. 10 refs., 5 figs., 2 tabs.

    With an objective to preserve the environment and reduce load on a deodorizing device, discussions were given on a high-efficiency hood for printing machines in a print shop. Solvents discharged from this factory consist of ethyl acetate, isopropyl alcohol and toluene, whose maximum total permissible concentration is 147 ppm. Two kinds of hoods with different opening areas were fabricated on a trial basis as hoods for monochromic gravure printing machines. Elucidation was made on the relationship of concentrations in a laboratory and ducts with discharged air amount. Collection effect is greater in a hood with higher face air velocity at the opening portion. It was made clear that the minimum air discharge amount that can clear the permissible concentration is 1000 m{sup 3} per hour inclusive of the safety factor. This value is derived under a condition that the secondary drying blower is stopped during printing work and the drying portion is shut off. For the similar purpose a hood for two-color gravure printing machine (with the first and second printing portions provided with hoods and installed with resistance plates to equalize face air velocity between both hoods) was fabricated on a trial basis for discussion. The minimum required air discharge amount was estimated to be 1100 m{sup 3} per hour. Total air discharge amount when all the printing machines are operating would be 10400 m{sup 3} per hour, and the concentration would be 690 ppm. 5 refs., 11 figs., 3 tabs.

    The phenomena on a cacogenesis of the blue green algae in the lakes subjected to an eutrophication occur frequently at every places in the world, and therefore they become a serious environmental problem. Especially it is known that a part of the blue green algae produces a toxic compounds, and consequently the issues of this kind is made further complicated. One of the blue green algae occurring universally at every place in the world is the microcystis genus, and moreover it often produces the microcystin group which is a peptidic hepatic toxin. Because the microcystin was a strong hepatic toxin, the toxicity testes using the mice have been exclusively executed. However, because the constituents reached up to 50 items, and in addition a toxicity of each element is not necessarily same, it has been considered that a chemical analytical method to perform an accurate separation and a sure detection have been necessary. A high-performance liquid chromatography (HPLC) is currently the most much used for an analysis of the microcystin. In order to detect the microcystin, the ultraviolet rays (UV) near 240 nm being its absorption maximum are being frequently used. However, a toxicity manifestation mechanism of the microcystin and so forth has not yet been elucidated. 24 refs., 2 figs., 2 tabs.

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

    Medicines have its peculiarity which is concerned in health and life of a human being, hence it is important to secure its validity, safety and high quality, and it is demanded to establish firmly the quality control system from research and development throughout production, logistics, up to usage. Accordingly, in order to export medicines overseas, it is required to validate that the medicines are manufactured in accordance with GMP (good manufacturing practice) of the country of destination. When Kajima Construction Co. designed and constructed a pharmaceutical plant to manufacture injections to be exported to the U.S.A., it planned and executed the validation technique from the viewpoint of quality assurance of the manufacturing environment as the GMP qualified plant, hence in this article, the outline of the above is reported. With regard to application of GMP, differences between Japan and the U.S.A. are pointed out. Also systematization of quality validation of the manufacturing environment is commented upon. Furthermore, examples are shown concerning execution of validation, and the monitor facility corresponding to daily validation is described. 4 refs., 2 figs., 9 tabs.

    A coherent optical fiber communication method has possibility of large capacity transmission for future, but it needs a control of polarization state of optical signal. So it is important to clear the optical polarization characteristics of OPGW because the polarization state may change rapidly by alternative current or lightning. This report describes the experimental results of transient states of optical polarization and coherent transmission characteristics by large impulsive current in OPGW (200m length). The impulse current is maximum 16kA at peak and 1{times}10 us rise and tail time. Polarization states are measured by a real time stokes analyzer with 10 MHz band width. As a result, the maximum shift of polarization state on Poincare sphere is about 70 degree and the rise time is about 12us, which is much longer than current use time 1us. We found the reason that the polarization rise time is caused by the inductance of spiral current along twisted conductors of OPGW, which makes magnetic field along the fiber in OPGW so as to occur Faraday effect. The coherent optical FSK transmission characteristics in transient state of optical polarization by impulse current is also described. In the case of single detection, bit errors are caused when the polarization states of optical signal on Poincare sphere move about 150 degree from the polarization state of local optical source. And in the case of polarization diversity detection, bit error is not caused by any change of polarization. 7 refs., 31 figs., 2 tabs.

    Coherent optical fiber communication is an effective method to increase transmission capacity of the existing transmission route. However, it is necessary for this method to control the polarization state of optical signals. Composite fiber optic ground wire (OPGW) is a transmission route that is peculiar to electric power. It is considered that the optical polarization state through OPGW may fluctuate considerably due to the magnetic field generated by electric current. In this paper, it is predicted theoretically that the polarization fluctuation occurs due to the Faraday effect because the magnetic field is formed in the axial direction of the fiber by the spiral flow of electric current along the twisted strand around the fiber. In order to study the effects on the axial magnetic field, carried out is an experiment to add the axial magnetic field to the 10km drum-winding optical core wire through the toroidal coil. Both polarization rotation angle and ellipticity angle are changed up to 1.4 rad by the coil current of 10A. In the AC magnetic field, the bit error rate increases to 10{sup -2}, but it can be improved by the polarization diversity detector. 24 refs., 26 figs., 6 tabs.

    Mice acquire strong preferences for flavors paired with intragastric (IG) fat infusions. This IG fat conditioning is attenuated in double knockout (DoKO) mice missing GPR40 and GPR120 fatty acid receptors. Here we determined if GPR40/120 DoKO mice are also impaired in IG fat self-administration in an operant lick task. In daily 1-h sessions the mice were trained with a sipper spout that contained dry food pellets; licks on the spout triggered infusions of IG fat (Intralipid). The training sessions were followed by test sessions with an empty spout. GPR40/120 DoKO mice self-infused more 20% fat than wild type (WT) C57BL/6 mice in training with a food-baited spout (2.4 vs. 2.0kcal/h) but self-infused less 20% fat than WT mice in empty spout tests (1.2 vs. 1.7kcal/h). The DoKO mice also self-infused less 5% fat than WT mice (0.6 vs. 1.3kcal/h) although both groups emitted more licks for 5% fat than 20% fat. The DoKO and WT mice did not differ, however, in their self-infusion of 12.5% glucose (1.5 vs. 1.6kcal/h), which is isocaloric to 5% fat. A second 5% IL test showed that the DoKO mice reverted to a reduced self-infusion compared to WT mice. When the infusion was shifted to water, WT mice reduced licking in the first extinction session, whereas DoKO mice were less sensitive to the absence of infused fat. Our results indicate that post-oral GPR40/120 signaling is not required to process IG fat infusions in food-baited spout training sessions but contributes to post-oral fat reinforcement in empty spout tests and flavor conditioning tests.

    For the purpose of developing the technology to assess the CO2 storage amount using the tropical mangrove coastal ecosystem, survey was conducted in the mangrove tree area in Ishigaki island, Japan and in Trat province, Thailand, and a draft of the assessment method was worked out. As to the assessment of the CO2 existence amount by analysis of satellite pictures, the regression equation between the mangrove existence amount and Landsat satellite data was determined to study a method for assessment of the CO2 storage amount in the whole area for survey. Further, using the relational equation between NDVI and LAI, vegetation indices reflecting vegetation conditions, methods to estimate the CO2 absorption amount by photosynthesis of mangrove tree community, the CO2 emission amount by respiration and the net production amount. Concerning the technology to assess the terrestrial area photosynthesis CO2 absorption amount, methods were studied for direct measurement of the amount of photosynthesis/respiration of the leaf area of mangrove tree community and the respiration amount by area such as trunk, branch and root and for assessment of CO2 absorption amount. Besides, studies were made on a variety of items such as the CO2 absorption/emission amount by underwater photosynthesis/respiration and decomposition of organic substances, the seawater exchange amount, and the rate of decomposition of organic substances.

    Full Text Available The objective of this work was to evaluate root and nodule soybean lipoxygenases in Doko cultivar and in a near isogenic line lacking seed lipoxygenases, inoculated and uninoculated with Bradyrhizobium elkanii. The lipoxygenase activities from roots collected at 3, 5, 9, 13, 18 and 28 days post-inoculation and from nodules collected at 13, 18 and 28 days post-inoculation were measured. The pH-activity profiles from root and nodules suggested that the lipoxygenases pool expressed in these organs from Doko cultivar and triple-null near isogenic lines are similar. The root lipoxygenase activity of Doko and triple-null lines, inoculated and uninoculated, reduced over time. The highest lipoxygenase activity observed at the beginning of root formation suggests the involvement of this enzyme in growth and development of this organ. However, for nodules an expressive increase of lipoxygenase activity was noticed 28 days post-inoculation. Root and nodule showed, at least, two mobility groups for lipoxygenases in immunoblottings, with approximately 94 and 97 kDa.O objetivo deste trabalho foi avaliar lipoxigenases de raízes e nódulos de plantas de soja da variedade Doko e da linhagem triplo nula derivada, desprovida das lipoxigenases da semente, com e sem inoculação de Bradyrhizobium elkanii.

Os perfis de pH-atividade de raiz e nódulo sugerem que o "pool" de lipoxigenases expresso nesses órgãos não difere nos dois genótipos. A atividade de lipoxigenases nas raízes de Doko e Doko triplo nula, com e sem inoculação, declinou com o passar do tempo. A maior atividade de lipoxigenases no início de formação da raiz sugere o envolvimento desta enzima no crescimento e desenvolvimento deste órgão.

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

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

    With an objective to promote capital investments that have been fallen because of the recession in Japan, the Petroleum Department of the Agency of Natural Resources and Energy has decided to take the following measures limited to one year for application. The measures consist of the taxation system for high-level energy saving investment promotion and the taxation system for small business machine investment promotion. In the former system, facilities that are effective for promoting rationalization and serving for environment preservation are admitted a special depreciation of 30% (36% for small business) on acquired prices or a tax deduction of 7% (8.4% for small business). Tax deduction of 7% (8.4%) is granted on leased assets. However, machineries are subject to a requirement of the price to be higher than 2 million yen (2.7 million yen in leasing). As a result, petroleum product shipping facilities are also covered by the taxation measures. The latter system, which is intended to promote investments by small business corporations, admits a special depreciation of 30% and a tax deduction of 7% for machineries acquired at prices above 2 million yen. Electronic computers and facsimile machines are also subjected to the taxation measures if their prices are higher than one million yen.

    Safety measures and assessment technology were studied for the WE-NET project. As the study result in fiscal 1996, the information on safety design, anomaly and accident was collected and arranged. The information on safety measures, ideology and criterion was also collected by visiting some domestic and overseas organizations experienced about handling of liquid hydrogen (LH). The initial survey was made for the safety design ideology, analytical technique and disaster preventive measures of LNG systems as the similar cold liquid system. Accidents and explosion accident of a hydrogen production plant (water electrolysis) in Germany were analyzed. Events on storage tanks and leakage around the tanks were studied as typical risk of LH considering temporary and LNG system design information. The model based on the LH spillage test result and 3-D dispersion of vapor cloud were prepared by modifying a simulation code. The model allowed evaluation of the effect of explosion and fire accidents of compressed hydrogen gas and flying fragments on structures and people, and visual display of distances from a tank and damage conditions. 19 refs., 29 figs., 18 tabs.

    Tokyo Electric Power has realized a peak shift of 5% for the maximum power demand by various measures to cope with increasing power demand and differential rate by time zone, including expansion of the differential rate system and heat-storage systems. Some of more notable recent techniques are eco-ice and eco-vendor systems, the former storing ice in the heat-storage tanks and the latter strongly cooling vending machines during nighttime. The NAS battery system is being developed as the new technique for load leveling. The energy-related advisory organ for Minister of International Trade and Industry asks each industrial unit to save at least 1% of power on the annual average as the energy-saving measure towards 2000. The energy-saving measures promoted by the government for the coming winter are controlled release of wastes, efficient use of power, setting room temperature at 19{degree}C or lower and voluntarily refrain from commuting by cars. The US power industry is abandoning the concept of DSM in the midst of deregulation and increased competition, and cutting budgets for new energy development. California`s SCE is promoting energy-saving through expanded use of high-efficiency motors, accurate grasp of customers` needs and publicity activities through internet systems. 4 figs., 1 tab.

    The bio-film method is to utilize the purification force of a bio-film consisted of the microorganisms such as the bacteria, fungi, protozoa, micrometazoa and so forth, which are formed on the surface of the gravels at a bottom part of the river, for a polluted water purification. This bio-film method was developed for a purpose of to make its activity proceed artificially and efficiently insides the tank. If these protozoa and metazoa occur as a substantial quantity in the bio-film treatment method of the polluted lake water, as they exhibit a large force to decompose and make inorganic the algae, their mass colonization is extremely important. In actual site practice, because the bio-film quantity and the bio-phase fluctuate substantially depending on the inflowing pollution load quantity and the temperature, an investigation of the manipulation method, by which the bio-phase corresponding to an inflow condition can be dominant, is necessary. In addition, in order to effectively decompose and remove the 2-MTB, microcystin RR and so forth, because securing the colonization field for the useful microorganisms is essential, a development of the adhesion carrier in which the useful microorganisms are easy to live, is also needed. 9 refs., 5 figs., 2 tabs.

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

    Identification was intended on effects of such thermal factors as metabolic amount, environmental temperature and humidity, and clothing resistance on human body temperatures during works under hot environments. Therefore, measurements were carried out on human skin temperatures, rectum temperatures and humidity inside clothing, while amount of motion, environmental temperature, and clothing are changed in a constant temperature room and under a sun irradiation environment. Furthermore, a heat balance model was prepared, which divides the objects into an outer shell layer whose temperature changes depending on the result of this experiment and into a core having constant temperature characteristics. An equation to derive skin temperatures was introduced from the model. The equation formulated a calculation formula for heat accumulation in human body, which can be used as a hot heat index. Relationship between thermal factors and heat storage amount was investigated to consider a thermal limit for a physical work. An equation to derive skin temperatures was confirmed capable of expressing general change in skin temperatures, being proved by comparison with experiments. Calculation formulas for amount of heat stored in human body were shown capable of expressing influence of different thermal factors, the expression being useful as a hot heat index. Calculating the human body heat storage is very largely affected by effect of sweat to dissipate heat, hence it is necessary to improve the accuracy including that for body temperature adjusting reactions. 17 refs., 17 figs., 5 tabs.

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

    Coherent optical fiber communication method is effective for increase of transmission capacity of existing optical fiber. But it needs a control of polarization state of optical signal. Especially through OPGW (Optical fiber composite Ground Wire), the polarization state will be influenced by lightning. This report describes a field measurement of optical polarization characteristics in actual OPGW of Hokuriku electric company in the condition of lightning. Main results are follows; (1) In normal condition without lightning, the states of optical polarization have alternative fluctuations of 60Hz. (2) In lightning weather, the transients of optical polarization are detected 51 times in two half months. It is made clear that these transient states are due to lightning by checking the time of day with the time data of LLS (Lightning Location System) and with the time of power line trip. (3) By estimating the waves of polarization shift, the duration of transient is 2 - 5msec, the rise time is 50 - 200usec. and wave tail has damping oscillation of 2 - 5kHz. The maximum shift of polarization states on Poincare sphere is 165 degree, which means polarization changes almost opposite states. (4) By evaluating the locations of lightning with LLS data, the transient polarization shift is caused by lightning over 50 km from observed OPGW. And the short distance tends to the large fluctuation of polarization. This characteristics may have a possibility of application to lightning monitoring. 7 refs., 22 figs., 1 tab.

    Two proteins of the GRETCHEN HAGEN3 (GH3) family of acyl acid amido synthetases from the moss Physcomitrella patens conjugate indole-3-acetic acid (IAA) to a series of amino acids. The possible function of altered auxin levels in the moss in response to two different growth perturbations, elevated temperatures and darkness, was analyzed using a) the recently described double knockout lines in both P. patens GH3 genes (GH3-doKO) and b) a previously characterized line harboring an auxin-inducible soybean GH3 promoter::reporter fused to β-glucuronidase (G1-GUS). The GUS activity as marker of the auxin response increased at higher temperatures and after cultivation in the darkness for a period of up to four weeks. Generally, the double knockout plants grew more slowly than the wild type (WT). The altered growth conditions influenced the phenotypes of the double knockout lines differently from that of WT moss. Higher temperatures negatively affected GH3-doKO plants compared to WT which was shown by stronger loss of chlorophyll. On the other hand, a positive effect was found on the concentrations of free IAA which increased at 28 °C in the GH3-doKO lines compared to WT plants. A different factor, namely darkness vs. a light/dark cycle caused the adverse phenotype concerning chlorophyll concentrations. Mutant moss plants showed higher chlorophyll concentrations than WT and these correlated with higher free IAA in the plant population that was classified as green. Our data show that growth perturbations result in higher free IAA levels in the GH3-doKO mutants, but in one case - growth in darkness - the mutants could cope better with the condition, whereas at elevated temperatures the mutants were more sensitive than WT. Thus, GH3 function in P. patens WT could lie in the regulation of IAA concentrations under unfavorable environmental conditions.

    Auxin homeostasis is involved in many different plant developmental and stress responses. The auxin amino acid conjugate synthetases belonging to the GH3 family play major roles in the regulation of free indole-3-acetic acid (IAA) levels and the moss Physcomitrella patens has two GH3 genes in its genome. A role for IAA in several angiosperm--pathogen interactions was reported, however, in a moss--oomycete pathosystem it had not been published so far. Using GH3 double knockout lines we have investigated the role of auxin homeostasis during the infection of P. patens with the two oomycete species, Pythium debaryanum and Pythium irregulare. We show that infection with P. debaryanum caused stronger disease symptoms than with P. irregulare. Also, P. patens lines harboring fusion constructs of an auxin-inducible promoter from soybean (GmGH3) with a reporter (ß-glucuronidase) showed higher promoter induction after P. debaryanum infection than after P. irregulare, indicating a differential induction of the auxin response. Free IAA was induced upon P. debaryanum infection in wild type by 1.6-fold and in two GH3 double knockout (GH3-doKO) mutants by 4- to 5-fold. All GH3-doKO lines showed a reduced disease symptom progression compared to wild type. Since P. debaryanum can be inhibited in growth on medium containing IAA, these data might indicate that endogenous high auxin levels in P. patens GH3-doKO mutants lead to higher resistance against the oomycete.

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

Valores de interesse para facilitar a seleção foram obtidos nas correlações entre peso de cem sementes (tamanho de sementes e dias para atingir a maturidade, e entre tamanho de sementes e largura visual da vagem. Na correlação entre produtividade de grãos e tamanho de sementes somente os topocruzamentos com Doko foram significativos. As estimativas de correlações em plantas individuais tenderam a confirmar aquelas obtidas em médias de parcelas. Os valores de correlação foram diferentes entre os tipos (grão, broto/"natto" e hortaliça de soja envolvidos, o que sugere a adoção de estratégias de seleção distintas. O estudo de correlações para cada topocruzamento é importante, pois podem ocorrer diferenças no desempenho das plantas como foi observado nos resultados obtidos.

    Full Text Available A work was carried out with the purpose of verifying the biochemical changes associated to soybean (Glycine max (L. Merrill seeds osmoconditioning. Seeds of the UFV 10, IAC 8 and Doko RC cultivars harvested at R8 development stage and submitted to different treatments were used. The biochemical evaluations were performed during seed storage, after the hydration-dehydration process. Initially, seeds were osmoconditioned in a polyethylene glycol (PEG 6000 solution, with the osmotic potential of -0.8 MPa and 20ºC, for a period of four days. After that, seeds were dried back until the initial moisture content (10-11% and stored in natural conditions for three and six months. Two controls were used: untreated seeds (dry seeds and water soaked seeds. Seed changes in protein and lipid, hexanal accumulation and fatty acids contents were evaluated. The results showed that seed storage under laboratory natural conditions caused reduction in protein, lipid and polyunsaturated fatty acids content and promoted hexanal production. Storage periods reduced protein levels for all treatments, however the PEG 6000 treatment showed lower protein reduction. The soybean seed storage increased hexanal production, but hexanal levels were smaller with osmoconditioning comparing to the other imbibition treatments.

    Full Text Available Foi conduzido um experimento com o objetivo de avaliar a qualidade fisiológica de sementes de soja (Glycine max (L. Merrill , envolvendo as variedades UFV-10, IAC-8 e Doko RC, submetidas ao processo de hidratação-desidratação, seguido por uma condição de estresse induzida pelo teste de envelhecimento acelerado. As sementes foram pré-condicionadas em PEG 6000, com potencial osmótico de -0,8 MPa, a uma temperatura de 20ºC, por quatro dias. Em seguida, as sementes foram novamente desidratadas, até atingir o conteúdo de umidade inicial, sendo então submetidas ao teste de envelhecimento acelerado pelos seguintes períodos: 0, 24, 48 e 72 horas. As sementes pré-condicionadas foram comparadas com duas testemunhas: sementes não-tratadas e sementes embebidas em água. Após cada período de envelhecimento, as sementes foram avaliadas pelo teste padrão de germinação, comprimento de plântula e biomassa seca das plântulas. Em casa de vegetação, determinaram-se o índice de velocidade de emergência e a emergência final em substrato de areia. O tratamento de hidratação-desidratação em solução de PEG 6000 melhorou o desempenho das sementes em termos de germinação e vigor. O aumento nos períodos de envelhecimento acelerado influenciou negativamente o desempenho das sementes, em todos os tratamentos avaliados. Contudo, o tratamento com PEG 6000 foi satisfatório em manter a qualidade das sementes. A embebição das sementes de soja em água desmineralizada prejudicou a qualidade fisiológica. As variedades de soja mostraram resposta diferenciada aos tratamentos de hidratação-desidratação e aos períodos de envelhecimento acelerado.A work was carried out with the purpose of evaluating the physiological quality of osmoconditioned soybean (Glycine max (L.

    Full Text Available O objetivo deste trabalho foi avaliar os genótipos de soja BR86-5974, BR86-7396, Dourados, Doko RC, EMGOPA 305, IAC-9, BR-9 (Savana, UFV-1, UFV-9 e UFV Araguaia em relação à tolerância ao alumínio (Al em hidroponia e em solo. Na solução com Al foi medido o comprimento radicular. Em solo com 49% de saturação de Al avaliou-se área foliar, altura de planta, altura de inserção da primeira vagem, produção de matéria seca, produção de grãos e índice de colheita. Os genótipos BR86-7396 e IAC-9 são os de maior tolerância ao Al, e UFV-1 mostrou o pior desempenho. Houve correlação significativa entre alongamento radicular e produção de grãos (r = 0,705, área foliar (r = 0,645 e produção de matéria seca (r = 0,634. Isto indica que experimentos em hidroponia e solo são igualmente eficientes na seleção de soja tolerante ao alumínio. A variabilidade detectada sugere que o conjunto de genótipos de soja possui ampla variabilidade genética, o que é desejável em programas de melhoramento com o objetivo de elevar estabilidade de produção no Cerrado.

Esses resíduos foram colhidos em três estádios do desenvolvimento reprodutivo do sorgo: florescimento, enchimento de grãos e maturação. Os tratamentos estudados constaram da deposição desses resíduos na superfície do solo ou da sua total incorporação na proporção de 4 g kg-1 de matéria seca no solo (LEd, fase cerrado. Nos tratamentos com planta, mantiveram-se três plantas de soja (cv. Doko em vasos com capacidade para 3 kg de solo. Nos tratamentos sem planta, o solo foi amostrado semanalmente para avaliação das formas de N. Após a colheita da soja, amostras de planta e de solo, de cada tratamento, foram retiradas para determinar a absorção total de N e a influência desses resíduos no N disponível extraído com KCl 2 mol L-1. Os resultados revelaram que alguns resíduos culturais de sorgo afetaram, independentemente do estádio de colheita, o desenvolvimento da soja, a absorção de N, o peso de nódulos e a biomassa microbiana do solo. Tais efeitos também foram dependentes do método de incorporação do resíduo. O teor de carbono imobilizado pela biomassa foi maior quando os resíduos de sorgo foram distribuídos na superfície do solo.

    Full Text Available Przedsiębiorstwa prowadzą obecnie działalność w otoczeniu, które jest zmienne i turbulentne. Bardzo ważna jest umiejętność przewidywania trudności finansowych i ciągła ocena kondycji firmy, gdyż każda jednostka gospodarcza może znaleźć się na krawędzi bankructwa. Jedynie w takim przypadku menedżerowie mogą podjąć działania restrukturyzacyjne i ocalić ją od upadku. Jeżeli jednak nie wiedzą, jak zła jest sytuacja podmiotu, może być zbyt późno na jego reorganizację i ocalenie. Z tego powodu niezwykle ważne jest opracowywanie modeli pozwalających oceniać kondycję przedsiębiorstw i ryzyko bankructwa. Wnioski badawcze wyciągnięte przez naukow-ców w krajach wysoko rozwiniętych (takich jak USA, Kanada, Zjednoczone Króle-stwo czy Niemcy mogą okazać się przydatne przy opracowywaniu metod przewi-dywania upadłości w Polsce. Jednak polska gospodarka różni się znacząco od go-spodarek bogatych państw Unii Europejskiej oraz Stanów Zjednoczonych. Dlatego polscy pracownicy naukowi powinni koncentrować się nie tylko na badaniach pro-wadzonych przez Altmana, Tafflera czy Beavera, ale także wzorować się na doko-naniach naukowców z krajów rozwijających się, takich jak Malezja. Celem niniej-szego artykułu jest zaprezentowanie metod przewidywania upadłości w Malezji. Być może, warto byłoby przeprowadzić podobne badania w Polsce.
