Hot and humid weather in summer generally brings about discomfort. Experiments on which relative humidity makes effects on the comfort sensation were performed to the young and the aged using sensation vote. From July to October 1996, seven college students and eleven aged people were exposed for 2 hours under six different conditions in the Pukyong National University test chamber so as to determine the effects of relative humidity on thermal and comfort sensations. Subjects were wearing same clothes, and the mean clo value was 0.5. The mean radiant temperature was equal to the air temperature and air velocity in the occupied zone around 0.lm/s. In the experiments, it was found that discomfort could be largely reduced when the humidity is controlled to low values in the settled high temperature.

Group Decision Support System(GDSS) has been a rapidly emerging field of the 1990's. Whereas conventional Decision Support System(DSS) helps individual decision makers, GDSS are designed to help groups of senior management and professional groups reach consensus. However, empirical researches which required to establish the optimum GDSS specification are scarce. Along with this purpose, this paper was focused to investigate the effect of group decision factors on the efficiency of the group decision. In this paper, task types of group decision which were discussed as major variable at many papers were settled as environmental factor. The result has verified the importance of the role-related factors on the efficiency of the group decision. This fact highlights the need of more researches on the role-related factors in the group decision in the GDSS development.

The coverage of the National Health Insurance for the elderly is expanding to denture and implants. Although the National Long-Term Care Insurance was just being settled, Oral health service was not provided to the Elderly in Long-Term Care Facilities. The long-term care facilities had part-time facility doctors. However, there is no dentist in the long-term care facility because of lack of long-term care insurance-related legislations. The amendments of long-term care insurance-related legislations for the introduction of part-time facility dentists are needed because the elderly in long-term care facility are vulnerable to oral health. For the substantial management of the National Long-Term Care Insurance, the development of oral health service model for the elderly and education materials for the dental team will be needed. Also, adequate dental service fee of the National longterm care insurance will be needed.

With the recent rise of apartment houses, the Korean government set up the Apartment House Manager System in 1989. In fact. a similar was originally introduced and fully settled down in England where the apartment house have been developed for a while. This study is primarily concerned with the comparison of apartment house manager system between Korea and England, with special respect to the background, the department in charge, the qualification of examinees, and the subjects for examination. The first part of this study deals with the difference of system between Korea and England. Among the most salient difference is that the system of Korea was established by the gorvernment itself in order to solve some problems derived from management, whereas that in England came into being for citizens to help the poor with housing problems as a Chrisitian social movement. The second part of this study suggests that it is necessary to open a department of apartment house at the two-year colleges. In addition, it would be advisable to give some advantages such as full a partial exception from examination to those who graduate from four-year universities or colleges.

This study was to examine the utilization of waste egg snells for removal of heavy metals in laboratory wastewater. It was estimated that pH increasing formed heavy metals into a hydroxide and then settled to remove them. Removal rate of heavy metals were increased as increased dosage, low adsorbate concentration and passed reaction time. Average adsorption volumes of Cr, Cu, Mn and Pb per g were about 1.21 mg, 1.1 mg, 0.96 mg and 1.04 mg, respectively. If we reflected the adsorption capacity(k) and adsorption intensity(1/n) of Freundlich isotherm, we couldn't consider waste egg shells as a good adsorbent. It seemed that heavy metals contained in complex wastewater was removed to be influenced by inital pH, solubilities with passed reaction rime and competitive reaction.

Highly advanced technologies are being adopted into the domestic construction industry in accordance with rapidly changing global construction industry in the 21st century. Value Engineering methodologies have often been discussed but not yet settled in the country. This research, therefore, aims to provide a useful guide to utilizing design Value Engineering in Build Transfer Lease. 1. Questionnaires had been conducted, answered by those in the field. 2. Questionnaires were in regard to the obstacles in the application of design Value Engineering and activation schemes. 3. Five standards were provided to be chosen according to the degree of influence from each factor, whose answers were technically analyzed by a statistical program afterward. 4. Four obstacles classified in this method were approached systematically to analyze the problems. 5. Efficient Activation schemes have been suggested after various analyses in a variety of aspects.

Transcranial doppler ultrasonography (TCD) is a new, non-invasive and easily applicable method to evaluate cerebral hemodynamics. Last 10 years, its use in Korea has been dramatically expanded, but the qualification of TCD laboratory has yet to be settled. Since duplex sonography is seldom used in Korea, we have to depend totally on TCD to evaluate cerebral hemodynamic changes. Thus, all of the available data from every detectabler cerebral arteries has to be obtained for accurate interpretation of TCD measurements. Moreover, flow direction and wave form should be concerned in addition to the flow velocity. In this article, I present technique to measure the anterior, meddle and posterior cerebral arteries, the internal carotid artery siphon and at cervical level, and the vertebral and the basilar artery, and normal values for these measurements which is essential for the adequate interpretation.

This article investigates and evaluates the relics settled from the center of the chest of triad Buddhist statue which is located in the temple of Wangryong in KyungJu as a whole. Especially, it focuses on the evaluation of the value of classical book in the course of research. As a result, it is revealed that classical books, such as Dohaekumeangkyung, Myobubyeonhwakyungsammae chambub, Jangsukyung, Seonjongyounggajib are as important printing much as to be national treasure.

During the last 20 years, transgenic animal technology has provided revolutionary new opportunities in many aspects of agriculture and biotechnology. Several gene delivery systems including pronuclear injection, retroviral vectors, sperm vectors, and somatic cell cloning have developed for making transgenic animals. In the future major improvements in transgenic animal generation will be mainly covered by somatic cell cloning technology. Many factors affecting integration frequency and expression of the transgenes should be overcome to facilitate the industrial applications of transgenic technology. Transgenic animal technology has settled down in some areas of the biotechnology, especially the mass production of valuable human proteins and xenotransplantation. In the 21st century animal biotechnology will further contribute to welfare of human being.

The basic experiment on the telemetry system of temperature and salinity, which is a study for the effective management of costal fishing-ground nowadays, was carried of 8 days from April 5, 6, 26, 27 , 1996 to May 31 and June 1, 21, 22, 1996 at the fish farm of Yooksam at Samyang-Myun, tongyongkun(34。45.02'N, 128。24.79'E). The results obtained were as follows : 1. The average temperature and salinity of STD of telemetry system was coincided with that of ICTD system calibration precisely. 2. A daily variation of temperature in fish cage which was measured by the telemetry system was influenced mainly by sunrise and sunset. 3. A daily variation of salinity in fish cage which was measured by the telemetry system was influenced mainly by tidal current. 4. The fish school in fish cage was distributed mainly 2~7 m layer during daylight and was arisen to the surface at sunset, was settled down to the bottom at sunrise.
