In order to provide fundamental data for development of controlled environment facilities in Korean ginseng (Panax ginseng C.A. Meyer) cultivation, field survey and analysis of structural and environmental engineering characteristics on the shading structures in ginseng fields (the ginseng houses) were carried out. In this study shading structures for ginseng cultivation were classified according to their structural materials, connection types, and detailed structures. That is they were classified into wood or steel frames, single or multi spans, and frame or cable types. As a result of the investigation, standardization of structural materials, fabrication and construction methods arc required. And it was considered that a reinforced design and a countermeasure for heavy snow are the most important matters for structural improvement. In parts of the environmental management, researches for setting up the irrigation standard are required in the first place. And it was investigated that an installation of the shading structures is a work being the most hard, taking a lot of time, and having need for automation. So controlled environment ginseng houses, with a low cost, a structural safety and a satisfactory workability, should be developed.

최근까지 물 부족을 해소하기 위한 방법으로 용수공급 확대만이 유일한 방법인 양 인식하여 왔다. 그러나 최근에 이르러 우리나라는 가용 수자원의 부족, 댐 개발 적지의 고갈, 지역주민의 집단반발 등으로 용수원의 적기확보가 난관에 봉착하고 있다. 갈수록 어려워지는 용수원 확보로, 급증하는 용수수요를 어떻게 충족시킬 것인가에 대한 진지한 논의가 필요한 시점인 것이다. 수자원의 확보가 심각한 사회문제로 대두되고 있고 물 부족 사태가 언제 올지 모르는 시점에서 앞으로의 용수수요에 대한 추정이 맞지 않고 용수량을 과다측정 또는 과소 측정하는 가장 큰 이유 중의 하나가 과거로부터 축적된 데이터의 부족이라 할 수 있다. 그럼에도 불구하고 기존까지의 용수수요예측에 관한 연구는 부분적인 연구결과만 있을 뿐 전반적인 이론 및 기법에 관한 정립이 되어 있지 않은 실정이다. 용수수급의 효율화는 수요측면과 공급측면을 조화롭게 운용함으로서 가능해지는 것으로 용수수요를 정확하고 신속하게 예측하는 것은 용수공급능력의 확대와 동일한 효과를 나타낸다. 그러나 인구, 생활양식, 문화수준, 산업구조, 용수요금, 소득, 기후조건 등 각종 요인을 종합적으로 분석하여 장래의 용수수요예측을 한다는 것은 현 기술 상태에서 매우 어려운 일이다. 따라서 본 연구에서는 금강유역을 시범유역을 선정하여 금강유역내의 용수수급현황을 직접 현장조사를 통해 파악하고, 현재 용수수급현황 파악에 있어서의 문제점과 향후 체계적이고 정확한 용수수급현황 파악을 위한 방법을 제시하고자 한다. 이를 위해 주요 생활용수, 공업용수 취수장을 직접 방문하여 용수사용실태를 조사함은 물론 금강홍수통제소에서 운영하고 있는 하천유수사용실적 관리시스템의 필요성과 문제점을 동시에 분석해보았다. 더 나아가 지속적인 용수사용실태를 조사하여 표준권역별로 물이용 지표화를 제시함으로써 향후 용수사용실태 분석시 효율성을 극대화 시키는 방안을 제시한다면 용수수요추정 오류에 따른 부작용을 최소화할 수 있을 것으로 판단된다.

When a heavy rain occurs, many electrical shock victims are produced every year because lamp poles are under water. In order to prevent electrical shock accidents at a street lamp, the investigation was carried out at real field conditions. The investigation was performed about the circuit configuration of a panel board, a wiring method, a grounding conductor, a lamp pole and so on. The related regulation was analyzed and the problems were presented. Also, the domestic and foreign things were compared and analyzed by the investigation of the field conditions, and the related standard was already revised. Through investigating the field conditions and analyzing the related regulation, it is intended to present the real data to establish more effective preventive measures against electrical shock accidents at a street lamp to be installed on the road. In the future, the analytical data can be applied to stabilize other electrical facilities on the road as well as a street lamp, and to reduce the electrical disasters.

This paper studies the leakage situation of domestic residential building underground parking lots and main leakage areas. 18 complexes were studied and the results showed that 80% of buildings with exterior waterproofing had no leakage, but all buildings with interior waterproofing had leakage. According to a survey among professionals, water leakage problems are considered to be severe in underground parking lots and a preventative measure is required by the government. By comparing the survey and the actual situation at hand, the results showed that the lowest floor slab, wall construction joints, and floor expansion joints were the most prone to leakage. Based on the results, further study to develop a design manual for the appropriate prevention of leakage is deemed necessary.

The purpose of this study is to clarify the fault structures in the Chukaryong Rift Valley. The Rift Valley has very significant meaning to interprete the development of Korean structural landforms. But till now the mechanism and processes of the formation of the Rift Valley are not clearly proved IMAGEM is very useful in this study. IMAGEM is developed by the Electromagnetic Instrument, Inc. and it covers $0.001{\sim}20,000Hz$. Form the fold survey data, it is certain that the faulted structures exist in the two points of the Rift Valley. But the Rift Valley is too long and braod to check the all evidences of the faulted structures.

Since 1960s the rural population of Korea has continually decreased as a result of the rapid rural-to-urban migration and this caused an economic recession as well as the accelerated aging phenomenon in the rural communities. Such problems got worse in smaller rural villages and marginal villages began to appear among the rural communities. This study aims to analyze the structures and characteristics of rural marginal villages. A case study on the county of Goheung, Jeollanamdo, is carried out using survey and stakeholder interviews. With the survey results a series of comparative analysis are done revealing the commonalities and peculiarities between two different types of marginal villages. This study also tries to reveal the residents's perceptions on the marginal villages and the potential determinants of rural rehabilitation.

The critical need of forest road for enchanting the additional values of various forest products, in addition, giving more recreational opportunity to citizen, has been recognized. In this study the present author aimed to ascertain the most effective construction working plan of forest road being tit to Korean geographic condition. To execute this research program, four locations in national forest of Kangweon-do district and other four locations in private forest in Chollabuk-do district both where forest roads have previously been constructed were selected to analyze the effectiveness basing upon the various factors separately or in combination. The results are summarized as follows ; 1. The investment efficiency in forest road construction showed to increase in the area where terrain factors and district social factors rate is high, and to decrease in the area where forest status factors and forest road structure factors rate is high. So in future the Forest Resource Development Model of forest road should take more importance particularly on those area having terrain factor ratio is low. The extractable value of constructed forest road based on forest status factors rate is expected to increase in case of high considerably. 2. To construct of forest road for increasing multiple use of forests, forest road should be construct with priority on area where obtained total score by evaluation factors is high. And these evaluation factors should take possible determine the position of forest road construction. 3. The following five types of forest road basing upon function performance are suggested with regard to the place where road is constructed. (1) Forest Utilization Model ; where forest status factors and forest road structure factors rate are over 60%. (2) Forest Resource Development Model ; where terrain factors, forest status factors, forest road structure factors and district social factors rate are less than 60%. (3) Community Development Model ; where terrain factors, forest road structure factors and district social factors rate are over 60% but forest status factors rate are less than 60%. (4) Recreation and Health Model ; where terrain factors, forest status factors, forest road structure factors and district social factors rate are over 60%. (5) Multiple Use Model ; where both forest status factors and district social factors rate are over 60%.
