The apartment will be much more convenient than the other one in the application of green technologies, providing the merits by mass production. For example, pre-manufactured building materials can be effectively adapted to the formation of buildings. Recently, the form of double-enveloped window system has been developed for the purposed of minimizing energy loss occurred around windows. On the other hand, the expansion of balcony area was legalized and thus, a visual buffer area does not exist any more. All-glass window wall on apartment houses without a balcony produces pretty harmful area with direct sunbeam. A various types of glass can be applied to the window system and it plays a critical role in the determination of inner visual environment. For the purpose of verifying the potential of its daylighting, a mock-up model has been constructed and tested. The refurbished version of conventional window shows its illuminated characteristics. Clear and Low-e glass have been adapted for window area and daylighting ratio has been compared in both test cells.

The total yield of Pinus koraiensis stands was reviewed along forest function by using goal programming, which is one of the operations research techniques. The 4 kinds of management goals are set to identify timber production in the Research Forest of Kangwon National University. As a result, scenario 1 was estimated the best timber production over 2,073 ha area and also 588 ha in the third quarter was showed the most timber harvest. The rate of timber harvest was separated by 10 to 50 percent in non-timber forest function in the scenario 1 and that model was applied to the Research Forest of Kangwon National University. The structure of the area and volume is showed to be balanced quarterly when rate of timber harvest at 10 to 20 percent.

The purpose of this study is to analyze the status and the competitiveness improvement of game contents industry comparing to relative LQ index of the no. of character company, the no. of employee and the amount of revenue of 2011, 2012, and 2013 between including Metro area and regional blocks(kangwon, chungchung, daekung, honam, dongnam and jeju region. The results of this research are as follows. In case including metro regional analysis, no. of employee suggested Metro and Chungchung have high competitiveness in during the 3 years. And in case of no. of game company suggested honam, dongnam and jeju area have high competitiveness between 2012 and 2013. The amount of revenue of game industry indicated the only Metro area have over LQ 1.0 which relative higher competitiveness than the other culture contents industry. But in case of except of Metro, no. of game company indicated honam, jeju have relative high competitiveness over LQ 1.0 and the no. of employee indicated kangwon, chungchung, honam and jeju showed relative competitiveness during 3 years. The amount of revenue of game industry indicated kangwon, chungchung and honam suggested high competitiveness. Honam area have strong competitiveness among three category by regional longitudinal analysis. Kangwon and jeju area suggested 2nd strong regional competitiveness. The main competitiveness of game industry were well established among national industry cluster.

Estimations of porosity and bulk density, particle size analysis of soli samples, tracer test and slug test were performed in a petroleum contaminated area of Kangwon for understanding characteristics of the aquifer. Porosities of the samples were estimated 0.158~0.257, and bulk densities were estimated as $1.73\sim2.10\;g/cm^3$. Majority proportion of the soil samples was 0.5~1.0 mm size. In the soil texture triangle, all samples were distributed at sand area. Uniformity coefficients were estimated as 7.71~10.39, and thus all samples were poorly-sorted. In the tracer test, Darcy velocity was estimated to $4.8\times10^{-6}$ cm/day, effective porosity was 0.175, and longitudinal dispersivity was 0.1 m. According to the slug test, hydraulic conductivities of the test wells were estimated as $2.243\times10^{-2}\sim1.634\times10^{-2}$ cm/sec. These hydrogeologic parameters can be used for efficient remediation design of the petroleum contaminated area.

Wild boars (Sus scrofa) not only cause crop damage and human casualties, but also facilitate the spread of many infectious diseases in domestic animals and humans. To determine the efficiency of a fencing system in blocking the movement of wild boars, long-term monitoring was performed in a fenced area in Bukhansan National Park using camera traps. Upon monitoring for a period of 46 months, there was a 72.6% reduction in the number of wild boar appearances in the fence-enclosed area, compared to that in the unenclosed area. For 20 months after the fence installation, the blocking effect of the fence was effective enough to reduce the appearance of wild boars by 92.6% in the fence-enclosed area, compared to that in the unenclosed area. The blocking effect of the fence remained effective for 20 months after its installation, after which its effectiveness decreased. Maintaining a fence for a long time is likely to lead to habitat fragmentation. It can also block the movement of other wild animals, including the endangered species - the long-tailed goral. This study suggests a 20-month retention period for the fences installed to inhibit the movement of wild boars in wide forests such as Gangwon-do in South Korea. To identify how long the blocking effect of the fences lasts, further studies are needed focusing on the length and height of the fence, and the conditions of the ground surface.

Sediment-laden water is problematic in aquatic ecosystem and for hydraulic structures in a watershed, and agriculture area in a watershed is one of source areas of nonpoint source (NPS), since soil surface typically exposures due to agricultural activities. Especially, severe sediment might flow into stream when agricultural area is located near stream like the Imha-dam watershed. Soil erosion is affected by precipitation, therefore there is a need to consider precipitation characteristics in soil erosion and best management practices (BMPs) simulation. The Web-based Spreadsheet Tool for the Estimation of Pollutant Load (STEPL WEB) allows estimating long-term sediment loads and the impact of best management practices to reduce sediment loads. STEPL WEB and predicted precipitation data by MIROC-ESM model was used to estimate sediment loads and its reduction by filter strip and conversion of agricultural area to forest in the future 30 years. The result indicates that approximately 70 % of agricultural area requires filter strip installation or that approximately 50 % of agricultural area needs to be converted to forest, for 41 % of sediment load reduction.

본 연구에서는 국내 동상피해 발생지역 중 동결지수가 높은 강원산간지역의 콘크리트도상 현장에 대하여 동상피해 원인과 동결심도를 분석하고 동결심도 자료를 바탕으로 콘크리트도상의 동결심도 산정식 및 강원지역의 동결심도 산정식을 고찰하였다. 강원산간지역의 콘크리트도상 동결심도와 강원지역의 동결심도 경향성을 비교한 결과 콘크리트도상은 동결지수 400(℃×일)이하에서는 동결심도가 강원지역의 동결심도보다 높게 나타났으며, 동결지수400(℃×일)이상의 구간에서는 강원 지역의 동결심도가 콘크리트도상의 동결심도보다 높게 나타났다. 본 연구를 통해 강원지역의 동결심도 산정식을 제시하여 강원지역의 철도 및 도로 건설사업 시 동상 방지대책 수립에 활용될 수 있도록 기초자료를 제공하였다.
