This study aims to estimate the Green-House-Gas emissions from domestic farmed flounder in the southern sea and Jeju-Do, where is mainly produced, by the assessment of energy consumptions and GHG emissions from domestic fish farms for establishing reduce standards of greenhouse gas from a sustainable perspective. It needs to analyze such GHG emission components as feed, electricity, fuel, fixed capital, fish respiration, and liquid oxygen in two locations by 4 stage running water type farm size of small, small and medium, large and medium, large scale. The result showed that the mean GHG emissions were $36.83kg{\cdot}CO_2/year$ in the southern sea and $24.33kg{\cdot}CO_2/year$ in Jeju-Do, respectively, in the stage of production per fish 1kg at 2 locations and farm size from domestic farmed flounders, and it will give to be useful for policy, planning, and regulation of aquaculture development with establishing GHG reduction standards.

This study was carried out to investigated the water requirement of twisted sweet peppers which are cultivated in a green house. The meteorological conditions during the experiment period was close to that of normal year except the temperature and relative humidity. The growth status was improved with the increased saturation ratio. The range of the variation of daily water requirement were very large. The peak consumption occurred in the early August. And the higher saturation ratio resulted in higher water requirement. The total water requirement were about 57.180g/d/plant for pot with 100% (P100) of saturation , about 38.700g/d/plant for pot with 80%(P80) of saturation , about 23,720g/d/plant for pot with 60%(P60) of saturation, and about 53, 390g/d/plant for field cultivation in the green house, respectively. The water requirement was correlated with average ambient temperature and growing status, while no significant correlation were found between water requirement and minimum relative humidity or intensity of solar radiation. And the higher correlation was shown as the saturation ratio was increased. The transpiration coefficients of twisted sweet pepper were 378.0g/g for field cultivation in the green house, 363.3g/g for P100, 338.7g for P80 which was the smallest among pot cultivation , and 472.1g/g for P60 , respectively.

The study set up the models of a general standard apartment house and a super high-rise standard apartment house, which were based on the 5 floor plans of the assessment reference houses of the "green homes" provided by the government; such main construction materials as to account for more than 80% of the entire amount of $CO_2$ emission in a construction work were selected; a database was built up for evaluating the environmental loads of the main materials according to the house types that were different from each other in area, block type, combination of living units or floor; and using the database, an attempt was made to develop the technology to assess $CO_2$ emission from the production of construction materials used in the stage of construction.

Root-knot nematodes cause a significant damage on fruit yield and quality of green house growing crops. To asses the effect of eggplant rootstock, Torvum vigor', TaibyouVF' and 'Daitaro' were grafted on eggplants(Solanum melongena cv. Chookyang) and planted in root-knot nematode infested microplot in green house and compared their fruit yield, quality and plant growth with non-grafted control. Eggplant grafted with Torvum vigor had the highest fruit yield and top growth and followed by Daitaro. Non-grafted eggplant had lower yield but had higher root weight because of heavy root-knot nematode infection. Rootstock grafting in eggplant farming is a good alternative technique in root-knot nematode infested green houses without compromising fruit yield and can be applied instantly as organic farming practice.

The rural area has aged and depressed for urban area in Korea. Furthermore, the rural house has deteriorated and is vulnerable to disaster which collapse, fire, landslide, and so on. For this matter, it need to an evaluated system for deteriorated level of rural house. The evaluated system has a repairing method and an estimated cost for rural house to offer native in rural area. This study could draw evaluation factor for deteriorated level of rural house as a basic study for the evaluated system. The evaluation factors is compared the Korean housing performance grade indication system, the Korean green building certification criteria, and the Japanese housing performance indication system. As a result, they could eight types. There are a mothproof, an waterproof, a finishing material, an asbestos cement slate of roofing, a mobility right, an opening and closing of doors and windows, an indoor environment.

This study was carried out to analyze the effect of the farm management and productivity increase of cabbages growing in the plastic house based on application of green manure crops such as silage corn, haussolgo (Sorghum bicolar L. Moench), hairy vetch, etc. According to the effect of green manure crop grown in summer season, the biomass amount of the silage corn was the highest; 7,630 kg per 10a, the next was haussolgo, 5,620 kg per 10a. In terms of the fertilizer ingredients, the first of forage soybean was 3.84% of nitrogen, whereas hairy vetch was 1.74% of phosphate and kalium, 4.74%. Productivity increase of cabbages was the highest in the haussolgo plot of which the yield of showed 10,090 kg per 10a and the farm household income would be worth 8,053 thousand won. By growing forage crops in the winter season, the biomass amount was the highest in the mixed sowing plot with rye (50%) and hairy vetch (50%) of 3,590 kg per 10a, whereas the productivity in the mixed seeding with rye (70%) and hairy vetch (30%) was highest, 6,249 kg per 10a and the farm household income would be worth 7,387 thousand won. Judging from these results, more practical on-farm research on applying different green manure crops as a basal fertilizer with cabbage in the plastic house should be considered to analyze the farm management and the farm household income at different sites.

The purpose of this study is to suggest improvement plans of school green building certification system in the concept of the Green Building Index by comparing items of domestic system with those of foreign system. School is a public facility for students. So Green Building Certification System for School must have educational point of view adding to energy saving, reduction of greenhouse gas emission, etc. Also school is forming a large part with the apartment house in the green building certification system. So we need to manage the green building certification system for school to meet carbon reduction policy.

The purpose of this study was to provide practical data for proposing the housing environment support policy, fit for returners-to-village. For the purpose, this study focused the patterns of returners-to-village according to their experience of rural life, and their ways of settlement like planning and getting land and house. The questionnaires were answered by 91 persons who were living in Chungbuk area, and were analyzed chi-analysis on their socio-demographic characteristics according to experience of rural life, preparation of settlement and construction. The ANOVA were used to analyze their pattern of return according to experience, the period for getting house, and their satisfaction level of house size. The results were as follows. First, the returners showed differentiated tendency according to their experience of rural life, in their age, family life cycle, education level and income source after return. The experience of rural life explained the purpose of return and the living pattern after return. Direct experience group was mostly occupational farmer; indirect experience group mostly pursued good health & green life; non experience group mostly pursued green life. Second, the experience of rural life also explained differentiated tendency of returning preparation. In raising money, direct experience group mostly raised it privately but indirect or non experience group mostly used bank loan. Third, the returners mostly constructed new houses; non experience group almost constructed newly, but there were cases to utilize existing or vacant house in direct experience group, and indirect experience group favored existing house or remodeling of vacant house.
