    Thanks to the energetic practice for 'New Gold Plan' made by the Ministry of Health and Welfare, various institutions such as 'Special nursing homes', 'Senior health centers' and 'Sickbeds for medical treatment' have been established. Even after the introduction of 'Public Nursing Insurance' in 2000, the special policy tentatively named 'Super Gold Plan' will be practiced, and we are going to have more complete institutions of such kind in the near future. We have been seeing the remarkable improvement of medical institutions recently, and it is said that the innovation of water-related fixtures has been taking a great part in their improvement. Then, this time, we would like to introduce the latest trends on water-related fixtures specially designed for medical institutions. (author)

    Iuchi, M.; Yamaoto, K. [Central Research Inst. of Electric Power Industry, Tokyo (Japan)


    A framework for the planning procedure is proposed to establish plans for lighting a city as a whole including the daily living space for residents to realize affluent national life and achieve well balanced public lighting in urban areas. The consciousness of urban residents to night-time environment comprises agreeableness with beauty and good atmosphere, static acativeness like quietness and composure, and attractiveness including intimacy and joyfulness. A questionnaire survey result reveals that most residents want such lighting be arranged in nearby squares or parks that enables calm and pleasant night-time activities. It is important to establish a lighting plan balanced both in regional and city scales, based on these needs of the residents. Also critical is to select the most effective business system including implementation systems and related organizations, and discuss specific processes in advance, including regulation and guidance of neon sign and signboard installations. 14 refs., 22 figs., 8 tabs.

    This paper describes the result of a toxicity test by means of a shaking culture on municipal sewage effluents using seaweed as a test living organism. Dead cells of porphyra yezoensis (nori) have emerged more specifically with the addition of non-disinfected secondary treated water at about 1% and with the lower the salt content. This phenomenon is thought to be an antagonism among growth accelerating substances for porphyra thallus, growth inhibiting substances, and salt content, one of the important characteristics of non-disinfected treated water. As a result of culture test on ripe seawater added with chlorine-disinfected secondary treated water, it was found that the growth of porphyra yezoensis (nori) is governed completely by concentrations of free chlorine added to the treated water, but very little by the treated water addition factor. Substances with very strong growth inhibition power, including NH4Cl, are generated in the chlorine-disinfected secondary treated water. It was disclosed that growth ratios of giant kelps at different factors of addition of non-disinfected secondary treated water change with the sampling time; water quality of the treated sewage water changes from one hour to another; and there are two time bands that show the growth ratio of about the same extent and a time band that shows a transition growth ratio. 60 refs., 8 figs., 2 tabs.

    Some of the exploration methods are taken up out of the geophysical methods, which have made drastic change by technological advancement, to discuss their technological development and application in cities. The elastic wave exploration is classified into the refraction method which uses refracted waves and the reflection method which utilizes reflected waves. Shallow reflection method allows visual observation of the complex underground structure, and is an excellent exploration method which provides highly accurate data. There are many types in the electrical exploration. New exploration methods have been developed as a result of improvement in the computer performance, advancement in the technology of numerical analysis, and improvement in the performance of exploration equipment, and they are being applied to the electrical exploration in many fields including tunnel and dam construction works. Geotomography is an application of the technology of medical tomography to ground exploration. Underground radar method is a method of investigating the ground structure by radiating electromagnetic waves from the ground surface in similar way to that of the reflection method and capturing the reflected waves from underground. 8 refs., 7 figs.

    Ogawa, Y.; Tokumitsu, N. [Nippon Steel Corp., Tokyo (Japan)


    Slag foaming caused by slag/metal reaction in a graphite crucible was observed with X-ray fluoroscopic apparatus in order to make clear the effect of bubble size on the foam height and the distribution of bubbles in slag. It was observed that the foam layer was formed when CO bubbles evolved at slag/metal interface became less than approximately 2mm in diameter. The foam height increased with the decrease of bubble size even in case of almost the same gas evolution rate. The size of bubbles decreased with the increase of iron oxide Content in slag and the decrease of sulphur content. It is considered that the bubbles become smaller when slag is wettable with metal. Therefore, the physical properties of slag/metal interface also affect the foam height besides the surface tension or viscosity of slag because they change the bubble size. (author)

    In the 21st century, reduction of environmental loads and creation of industries harmonizing with every city and region in the world are essential issues toward a sustainable society. Rapid conversion of a mass production/disposal society of resources and energy to a recycle-oriented comfortable city structure harmonizing with human being and nature is important. This paper clarifies the meaning of construction of a circulating/harmonizing society as condition of sustainable circulating urban structure, and points out the limitation of recycling technology from the viewpoint of entropy. The following themes are discussed for the role of technology for promoting circulating systems: an ecologically-sound-society under global environmental crisis, a sustainable city harmonizing with ecosystem, basic systems for the formation of an energy/resource recycling-oriented community, optimum operation of energy systems in recycle- oriented cities, an urban energy network and innovative element technology, and development of an urban simulator toward a self-sustainable and low-emission urban system. 5 refs., 13 figs., 1 tab.

    The town gas business is increasingly required to secure stable supply and improve safety and services in the midst of great changes resulting from deregulation and amended gas rate systems. Described herein are three major problems to be tackled in fiscal 1996, taken up by the Gas Association of Japan`s Tohoku Branch. The first one is promotion of natural gas introduction and standardization of town gas, for which Tobu Gas has started activities to change heating value of natural gas supplied from Akita Prefecture, and the Sendai Gas Bureau is introducing natural gas. The second one is ensuring safety, for which the enterprises concerned should strengthen cooperation to maintain and improve safety. The third one is expansion of gas demands and stabilizing the business, for which the business should overcome the problems, such as insufficient growth of the demands by domestic sector, increased prices of imported gas and introduction of new gas rate systems, and realize the low-cost business structures by further rationalizing the related facilities and improving the demands structures. 1 fig.

    For effective use of wastes, the concept of a waste utilization system suitable for local characteristics of the Kyushu district was surveyed. The amount, features and processing method of wastes were surveyed for every kind of wastes and every region. Characteristics of wastes themselves and their use technologies were surveyed to study the energy system concept, and the concept was selected mainly for simple middle or small-scale systems. Main wastes available as heat source showed distinctive distributions every region. The following seven concepts were thus selected: RDF (refuse derived fuel) energy system mainly using general wastes, RDF system using wood chips and agricultural plastic wastes, co-generation system by premixed combustion of chicken manure and combustion improver, premixed combustion of livestock manure and combustion improver, methane fermentation using livestock, distillery and starch wastes, and pyrolytic oil system or gas system using agricultural plastic wastes. Establishment of any systems is difficult only in single region because of their economic scale. The collection and storage methods of raw materials should be studied. 36 figs., 40 tabs.

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

    For the construction of houses that effectively utilize natural energy and impose less load on environments, an example of house building respecting environmental symbiosis is described. Reported herein are a heating system and the measurements of thermal environment in winter. In winter, the floor is heated by warm water from solar heat collectors circulating in pipes buried in downstair underfloor RC foundation. For the verification of the heating effect, comparison was made between the heater-provided southeast (SE) room and heater-unprovided northeast (NE) room, both downstairs. Warm water circulated in the underfloor pipes only in the daytime, the pipe surface recording the maximum of 32{degree}C in the daytime and the minimum of 17{degree}C early in the morning. At midnight, the SE room was warmer than the NE room by 2{degree}C. The slab surface in the SE room recorded 28{degree}C at the maximum and 17{degree}C at the minimum, but the temperature remained constant at 10{degree}C in the NE room. The rubble temperature was 17.5-20{degree}C in the SE room and approximately 11{degree}C in the NE room. It was noted that the SE room floor slab was capable of heat accumulation. The resident is a devotee of environmental symbiosis with mindset for enhancing natural energy utilization, burning an oil heater and a fireplace but intermittently. 1 ref., 12 figs., 1 tab.

    The effort of fiscal 1997 at isolating the best way to introduce a relatively small amount of hydrogen into urban fuel economy was carried over to fiscal 1998. In the research of fiscal 1998, comparison was made between Tokyo and London in connection with hydrogen introduction, and a transition scenario was proposed for introducing hydrogen into Tokyo. Models were built for Tokyo and London, and studied. The result of this study was different from that obtained in the previous study, and places the two cities under similar conditions. The difference is attributed to the rapid progress in the development of the fuel cell and to the resultant reduction in cost. It is inferred that, in consideration of the transportation situation, the introduction of pure hydrogen will be the most cost-effective for both cities at least for some time to come. According to the revised data, natural gas may be procured in Tokyo as in London but the size of supply available in Tokyo is fairly smaller than that in London. Several transition scenarios covering the period up to 2025 were subjected to discussion. (NEDO)

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

    Complex facilities consisting of offices, shopping centers and hotels were investigated to discuss synergistic effects of compounding the different uses. The investigations included an investigation on passing behaviors and traffic amount among facilities of different uses around and inside the complex facilities, a questionnaire survey on visitors for their composite utilization, impression and evaluation of the facilities and another questionnaire survey on office workers for their composite utilization of the facilities inside and outside the complex facilities. The result of analyses using simple calculations and multi-dimensional measure methods revealed the following points: improvement on images of the whole facility as a result of strong customer collecting power of the commercial facilities, support effects on hotels and malls, roles and utilization patterns of commercial facilities, hotels and various facilities existing in peripheral areas that function to support office works, and roles of open squares and malls that coordinate and integrate the facilities of different uses and promote passing activities. It was also observed that resident time is extended as a result of composite utilization, and that the shift in peak time of the number of people utilizing the commercial-based and office-based facilities results in more efficient utilization of parking lots and restaurants. 1 ref., 9 figs., 2 tabs.

    The locality in rental housing situation in provincial cities, Bandung (Java), Medan (Sumatra) and Ujung Pandang (Sulawesi) in Indonesia is clarified statistically based on fact-finding survey on condition of present and former housing, evaluation of present housing, improvement plan on housing and other items by questionnaire. The result shows that there is clear locality of physical conditions of rental housing among these three cities. Bandung shows locality based on urbanization as of Jakarta metropolitan area in smaller size, nuclear family and equipment level. Medan and Ujung Pandang shows locality based on specific character of the region such as large rental housing in Medan and provision of rental housing using ground floor level of traditional elevated floor houses in Ujung Pandang. Families in Medan and Ujung Pandang are generally extended families including brothers, sisters or relatives in addition to nuclear families, Consequently, is concluded that the construction of rental housing policy in Indonesia requires consideration of local characteristics. 7 refs., 11 figs., 5 tabs.

    The authors attempted to manufacture active carbon using potassium carbonate as an activator from a raw material of tofu refuse. As the results, the active carbon having a large specific surface area of 2,656 m{sup 2}/g at a carbide and an activation temperature of 800 degrees C could be manufactured. It was clarified as follows after investigating the activation mechanism: potassium carbonate changed to potassium peroxide and potassium sulfate in the reaction of tofu refuse and potassium carbonate in the impregnation and dry process. The tofu refuse was changed into a low molecular weight component and a water soluble organic constituent increased. As the results, the weight loss behavior of he tofu refuse changed up to the carbonization - activation temperature of 500 degrees C and then the carbide having a large specific surface area which had a different pore structure of carbide made independently from the tofu refuse was generated. With further increasing the temperature up to 700 degrees C, it was considered that carbon consumed due to a reduction of potassium carbonate by carbon of carbide, the specific surface area was greatly increased, and active carbon having a high specific surface area was manufactured.

    For suppressing and controlling the emission of dioxins in the flue gas from the city garbage incinerator, it is necessary to perform the complete combustion. The combustion state in the incinerator was investigated to understand the influence of combustion factors on the combustion. A computer simulation analysis on the gas flow in the incinerator was also carried out. The concentration of CO and O2 in the combustion gas leaving the incinerator and the temperature distribution in the incinerator were measured. The results showed that the atmosphere in the incinerator was distinctly separated into two zones, i.e., the high temperature zone where the O2 concentration was extremely low while the CO concentration exhibited its peak value and the low temperature zone where the CO concentration was relatively low and O2 concentration was excessively high. The effect of combustion gas temperature on the combustion reaction of unburnt gas was found to be high. When the combustion gas temperature was elevated, the CO concentration in the exhaust gas leaving the electrostatic precipitator was exponentially decreased. The relationship between the CO concentration and the O2 concentration could be expressed in a quadratic equation. There was a certain optimum O2 optimal concentration range for reducing the CO concentration. The O2 concentration was an important factor for controlling the combustion. The result of computer simulation proved to be shown well the combustion gas flow in the incinerator. 8 refs., 10 figs., 4 tabs.

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

    This paper is a translated, edited version of a lecture given at Business Consultative Meeting of Eight-Nation Energy Ministers` Conference convened in Moscow in March, 1998. This is a Russian investor`s opinion about the conditioning for the attraction of private sector investors to Russia`s energy industry. The economic development of Russia will depend on the magnitude and efficiency of the investment in oil and gas projects. So as to overcome the current inactivity of oil industry, Russia will need an investment of 6 to 20-billion dollars a year. Furthermore, according to the micro-economy level calculation, the required investment will be 130 to 140-billion dollars a year. Under the circumstances, what is necessary is to work out conditions to be most favored by the investors. For the attraction of an increased number of investors, two methods are under consideration. One involves the improvement of the currently valid underground resources utilization system (licensing system), and the other involves the formulation of a competitive underground resources utilization system based on the mechanism of agreement on products distribution. 4 figs., 1 tab.

    The paper described the fiscal 1997 result of the study of scenarios for introducing hydrogen to the urban area. In the case of studying it in London, it was found that hythane (mixture of hydrogen into town gas) was effective, but in the case of doing in Tokyo, it was found that the scenario was undesirable because of the increasing infracost. Accordingly, another scenario was studied. It was assessed from the aspects of environmental advantages, infracosts, and potential advantageous values in urban areas associated with hydrogen utilization (hydrogen premium). It is most effective to use hydrogen as a fuel of transportation means from the aspect of environmental merits as the decrease in external cost. In Tokyo, the dependence upon electric power is large, and therefore it is attractive to introduce highly efficient fuel cells which enable the dispersed cogeneration using hydrogen. The value of hydrogen is determined by the avoidance of environmentally influential substances and the surplus generated output by fuel cells (substitution for the existing natural gas). When the high external cost can be assumed, the value of hydrogen becomes large. The paper also considered the arrangement of infrastructures in Tokyo. 187 refs., 14 figs., 18 tabs.

    Described herein are the results of the FY1994 research program for solar/energy-conversion technologies retrofitted to existing buildings. The estimated effects and economic viability of retrofitting technologies show that they bring very high energy-saving effects when applied to heating and hot water supply, which consume a large portion of energy, but relatively low energy-saving effects when applied to cooling, solar walls, glazed balconies and transparent insulators. The study on applicability of these technologies in Japan indicates that the technologies which can recover cost within an average life time are those applied to windows, solar collector systems for hot water supply and heating, and transparent insulators. Although these technologies are low in applicability to cooling viewed from the angle of cost recovery, retrofitted radiation type cooling systems improve not only cooling and energy-saving effects but also comfortableness.

    In this study, we show the result of superposed epoch analysis on the THEMIS probe data during the period from November, 2007 to April, 2009 by setting the origin of time axis to the substorm onset determined by Nishimura with THEMIS all sky imager (THEMS/ASI) data ( We confirmed the presence of earthward flows which can be associated with north-south auroral streamers during the substorm growth phase. At around X = -12 Earth radii (Re), the northward magnetic field and its elevation angle decreased markedly approximately 4 min before substorm onset. A northward magnetic-field increase associated with pre-onset earthward flows was found at around X = -17Re. This variation indicates the occurrence of the local depolarization. Interestingly, in the region earthwards of X = -18Re, earthward flows in the central plasma sheet (CPS) reduced significantly about 3min before substorm onset. However, the earthward flows enhanced again at t = -60 sec in the region around X = -14 Re, and they moved toward the Earth. At t = 0, the dipolarization of the magnetic field started at X ~ -10 Re, and simultaneously the magnetic reconnection started at X ~ -20 Re. Synthesizing these results, we can confirm the validity of our catapult current sheet relaxation model.

    Back in the 1970s Stephen Hawking of Cambridge University in the UK made the theoretical discovery that small black holes are not 'completely black'. Instead, a black hole emits radiation with a well defined temperature that is proportional to the gravitational force at its surface. The finding uncovered a deep connection between gravity, quantum mechanics and thermodynamics. Later, Bill Unruh of the University of British Columbia in Canada proposed that quantum particles should emit thermal radiation in a similar way when they are accelerated. Now, Pisin Chen of the Stanford Linear Accelerator Center and Toshi Tajima of the University of Texas at Austin in the US have suggested that it should be possible to detect the Unruh radiation emitted by electrons that are accelerated by high-intensity lasers (Phys. Rev. Lett. 1999 83 256). In this article the author explains their proposal. (UK)

Methods: In this study, we examined the existence of regional structural abnormalities in both the gray matter and the white matter of patients with OCD at baseline using voxel-based morphometry in responders (n=24 and nonresponders (n=15 to subsequent BT. Three-dimensional T1-weighted magnetic resonance imaging was performed before the completion of 12 weeks of BT. Results: Relative to the responders, the nonresponders exhibited significantly smaller gray matter volumes in the right ventromedial prefrontal cortex, the right orbitofrontal cortex, the right precentral gyrus, and the left anterior cingulate cortex. In addition, relative to the responders, the nonresponders exhibited significantly smaller white matter volumes in the left cingulate bundle and the left superior frontal white matter. Conclusion: These results suggest that the brain

The neural substrate underlying the agitated behaviors in dementia is unclear. We hypothesized that different dimensions of agitated behaviors are mediated by distinct neural systems. Methods: All the patients (n=32 underwent single photon emission computed tomography (SPECT. Using the Agitated Behavior in Dementia scale, we identified the relationships between regional cerebral blood flow (rCBF patterns and the presence of each of three dimensions of agitated behavior (physically agitated behavior, verbally agitated behavior, and psychosis symptoms in AD patients. Statistical parametric mapping (SPM software was used to explore these neural correlations. Results: Physically agitated behavior was significantly correlated with lower rCBF values in the right superior temporal gyrus (Brodmann 22 and the right inferior frontal gyrus (Brodmann 47. Verbally agitated behavior was significantly associated with lower rCBF values in the left inferior frontal gyrus (Brodmann 46, 44 and the left insula (Brodmann 13. The psychosis symptoms were significantly correlated

The aims of this study were to accurately identify the natural course of depressive symptoms and the risk for developing major depressive episode (MDE in late adolescents with subthreshold depression over 1 year.Patients and methods: One hundred and seventy-two participants <20 years of age (mean age: 18.32 years, standard deviation: 0.50, who did not meet the full criteria for an MDE, were selected from 2,494 screened freshmen based on the Beck Depression Inventory, 2nd edition (BDI-II. We conducted a cohort study of three groups (low-, middle-, and high-symptom groups divided based on BDI-II scores, over a 1 year period with the use of bimonthly assessments. Temporal changes of depressive symptoms were analyzed using linear mixed modeling and growth mixture modeling.Results: First, we found that late adolescents with subthreshold depression (high depressive symptoms were split between the increasing and decreasing depressive symptoms groups, whereas the majority of the less-symptoms group remained

In addition, whether the abnormalities in WM integrity that underlie the delusions develop before the onset of the delusions remains unclear. In this study, we used a diffusion tensor imaging approach to examine the existence of baseline abnormalities in WM integrity in AD patients who developed delusions and AD patients who did not develop delusions.Methods: Using the Neuropsychiatric Inventory, we identified patients with AD who exhibit delusions during a 1-year period. All the patients underwent a magnetic resonance imaging (MRI examination at baseline. We conducted fractional anisotropy using tract-based spatial statistics software and compared the results of AD patients who developed delusions with those who did not develop delusions.Results: Compared with the AD patients who did not develop delusions (n = 15, the AD patients who developed delusions (n = 10 exhibited two relatively large clusters and one minimal cluster of significantly lower fractional anisotropy results. The first cluster was located in the left parieto-occipital region and included several fibers: the left inferior longitudinal fasciculus, the

However, little evidence of the efficacy of nonpharmacological interventions for agitated behaviors exists for patients with dementia. The present pilot study aimed to evaluate a behavioral management program developed by the Seattle Protocols for patients with agitated behaviors in Japan.Methods: Eighteen patients with dementia (Alzheimer’s disease, n = 14; dementia with Lewy bodies, n = 4 participated in an open study testing the effectiveness of a behavioral management program. The intervention consisted of 20 sessions over the course of 3 months. The primary outcomes were severity of agitation in dementia, as measured using the Agitated Behavior in Dementia scale (ABID and the Cohen-Mansfield Agitation Inventory (CMAI.Results: The behavioral management program resulted in significant reductions in total scores on both the ABID and CMAI. Although both physically agitated and verbally agitated behavior scores on the ABID improved significantly, symptoms of psychosis did not improve after the intervention.Conclusion: The behavioral management technique may be beneficial to distressed caregivers of

Adolescent self-harm was defined as an adolescent who had harmed himself or herself in the previous year, as in previous studies reported in Western countries. Poor help-seeking was defined as not consulting anyone despite reporting current psychological or somatic complaints. Information about sociodemographic and psychological factors possibly associated with help-seeking, such as suicidal thoughts, depression, anxiety, and psychotic-like experiences, was also collected. Regression analyses were performed to examine associated factors.Results: A total of 18,104 students (8620 aged 12–15 years, 9484 aged 15–18 years, accounting for 93% of all students in the relevant student classes, participated in the study.
