The variations of real time electric power price in competitive electricity markets have influence on electric power demands of the consumers. The effects of the consumers for electric power price can be expressed the price elasticity coefficient of the power demand as a measurement. Residential, commercial, and industrial consumers with different characteristics cause the different price elasticity of the power demand due to changing the pattern of consumption. It is necessary that the effects of electric power demands as a function of elasticity coefficient for each loads should be analyzed in Korea which is processing deregulated electric market. Therefore, this paper calculate the elasticity coefficient of each loads and analysis the effects of electric power demands as a function of elasticity coefficient of inflexible and flexible consumers in competitive electricity market.

As a pre-step research to make land-use planning in the region level, this study aims to analyze some probability pattern representing transition probabilities from farmland to others using the sequential detailed digital land-use maps. Kinki and Chubu regions of Japan, which have Osaka and Nagoya cities as their center places respectively, were selected as test regions in this study. The 10m grid land-use maps for four time series at every 5 year from 1977 to 1992 were used. In this study, the regions were divided into three sub-areas 10km, 20km, and 30km according to distance from center cities, respectively. The correlation coefficient (CC) between sub-areas with same distance in the two regions was calculated to analyze whether or not the two regions have common points in the pattern of land-use conversion probability from farmland to other types. The probability distribution of the converted areas which were moved to the urbanized area (residential, commercial, industrial, road, park and public facility areas) was about $40{\sim}70%$ for both all periods and sub-areas. According to distance from city centers, the probability moved to the urbanized area was about 60% at 10km area, and 40% at the 30km area, which means that the values we decreased gradually, while in the case moved to the forest and the etc areas, the values were increased slightly. The CC analysis from the paddy field and the dry field to the others separately showed that there is high correlation in the probability pattern between the two regions.

Housing for the elderly should be planned on the base of elder's needs and preferences as well as their physical, emotional, and socio-psychological characteristics. This study examined the interior style of bedroom and living room the elderly preferred and these preferences are significantly different depending on their characteristics and cognitive ages, or not. This study was carried out by face to face interview with a questionnaire and 6 colored printed 3D images. The subjects were 202 old aged who lives in Busan. The interior style of bedroom and living room were classified into 3 styles; Korean traditional style, Western classical style, and modern style. The subjects made a choice their preferred interior style among three 3D images per each room and answered the reasons. Also, they answered their cognitive ages and general characteristics, and their preferences for the layout of living room-dining room-kitchen, use pattern, floor finishes, and furniture of bedroom and living room. The results were as follows; 1) The subjects preferred bed in bedroom and sofa in living room. Also, they wanted to finish the floor of bedroom and living room by using synthetic material, traditional floor paper, and wood. 2) The elderly preferred Western classical style of bedroom. The reasons were general mood such as warm, comfort, or bright, and the color. 3) These preferred styles were not any significant differences according to their characteristics and cognitive ages. 4) They preferred Korean traditional style, Western classical style, and modern style, in order. They preferred them for their general mood and window. 5) Their preferred styles were significantly different according to their housing types and cognitive ages.

An attempt to clarify the landscape structure of urban areas was carried out in the greenbelt around Seoul, Korea's metropolis. By means of aerial photographs and a field survey, a vegetation map including land-use pattern was made. Landscape structure was described by analyzing this vegetation map and the results of phytosociological survey. Landscape element types identified were (1) secondary forest, (2) plantation, (3) cultivated field, (4) urbanized area, (5) graveyard, and (6) bare rock. Vegetation units, resulting from the phytosociological analysis, included Quercus mongolica, Q. variabilis, Q. acutissima, Pinus densiflora, Q. aliena, and Alnus japonica communities. Plantations were composed of Robinia pseudoacacia, Populus tomentiglandulosa, P. rigida, Larix leptolepis, P. koraiensis, and Castanea crenata stands. Patches near to human settlements in the lower zones of the mountains were fragmented and small but they became larger towards the higher mountain zones. On the other hand, the number of patches was fewer and their size was larger in Mt. Cheonggye more distant from the principal residential area, larger in size, and higher in elevation compared with the other 2 mountains, Mt. Daemo and Mt. Acha. Floristic composition of Mongolian oak(Q. mongolica) stand distributing in the upper part of each mountain, in which artificial interference is rare, showed a difference among those study areas different in parent rock and disturbance regime. But that of black locust(R. pseudoacacia) stand located in lowland of mountainous area, in which artificial interference is frequent was similar to each other. As the results of analyses on the frequency distribution of diameter classes of major species, dominant landscape elements, Mongolian oak forest showed different responses depending on artificial interference as continuous maintenance and retrogressive succession in the sites far from and near to the residential areas, respectively. On the other hand, black locust stands showed a probability to be restore to the native oak forest through progressive succession.

In this study, I investigate the formation process of the American presbyterian missionary architecture in Cheong Ju area from 1900 to 1945, which we may think 'the part of Korean modern architecture'. I have examined and analyzed the 18 buildings for the sake of the interpretation with the words of formation process and characteristics . And I can put my idea in order as follows. Firstly, the formation process is 1) buy and modify a Korean style (thatch or tile roofed) building for their need and use it as a gate quaters or house, church, hospital, school, book store, 2) build a Korean style (tile roofed) building and use it-house, hospital, school, 3) build a Western style (timber structured and zinc roofed) building and use it- church, 4) build a Western style (masonry structured and tile or zinc roofed) building and use ithouse, church, school and hospital. Secondly, the characteristics is 1) In the Korean style building, the missionaries change into the function to match with their purpose. they modify the Korean style timber structure by influx of building material-brick, glass, carpet etc. they occupy into the Korean existing residential area. 2) In the Western style building, the missionaries build the house correspond with their living pattern. they build the church with the eclectic of Western and Korean timber frame. and also build the house and hospital with the eclectic of Western and Korean masonry structure. their building located in the isolate hill separated from the existing Korean residential area.

Hydrogen is the primary fuel in fuel cell systems. Because of high inflammation and explosion possibility of hydrogen, fuel cell systems require safety measures to prevent hydrogen hazard upon leakage. In this study, a model enclosure was made by referring to a commercial residential fuel cell system and hydrogen leakage experiments and computational simulations were conducted therein. Hydrogen was injected into the cavity through leakage holes located at the bottom while its flow rate was precisely controlled using MFC. The transient sensor signals from hydrogen sensors installed inside the enclosure were recorded and analyzed. The hydrogen sensor signals showed different delay times depending on their position relative to a leakage point, which indicated that hydrogen generally moves upward and accumulates at the upper region of a closed cavity. The inflammable regions with hydrogen concentration over 4% LEL were observed to locate near the leakage hole initially, and broaden towards the upper cavity region afterward. The simulation result showed that detection time at the hydrogen sensor was similar to the pattern of experimental results. However, the maximum concentration of hydrogen had a gap between experiment and simulation at detect point due to measurement errors and reaction rate.

The total number of flies collected was 4,864 with sex ratio of 32.8% from Suseungdae area, Geochang-gun, Gyeongnam, Korea. The fauna of fly was 35 species consisting of 13 Calliphoridae, 12 Muscidae, 8 Sarcophagidae, 1 Dryomyzidae and 1 Anthomyiidae. The number of genus and species of Calliphoridae and Muscidae of Suseungdae area were similarly found in the mountain and residential areas, however, those of Sarcophagidae was similar with that of residential area. Calliphoridae was the most dominant family at the survey sites with 60.4% of the total collected flies, and followed Muscidae 33.3% and Sarcophagidae 6.2%. The dominant species were constituted of 83.6% of the total flies and the order of collected flies was Chrysomyia pinguis (42.2%), Limnophora sp. (10.8%), Muscina angustifrons (8.6%), Calliphora lata (8.1%), Fannia scalaris (5.5%), Lucilia caesar (3.9%), and Boettcherisca peregrina (4.2%). The seasonal prevalence of flies was from the middle of March to the end of November, and the peak time of appearance was the middle of June, middle of September and middle of October. The highest peak of prevalence was the middle of October. The similarity index of the flies was above 80%, compared to Mt. Geonheung and landfill in Geochang-gun. The number of fly species was more affected by the mean air temperature. In the comparison of the seasonal prevalence and relative abundance of 7 predominant species among 35 species, each species was found to exhibit its specific characteristics and showed the pattern of species.
