여가시간 및 소득수준 증가에 따라 다양한 활동들이 수상공간에서 일어나고 있으며 이를 수용하기 위하여 다양한 구조물들이 수상에 설치되고 있다. 그 중 플로팅 건축물은 친환경적이고 수상공간을 보다 적극적으로 활용할 수 있다는 이유로 최근 그 사용이 증가하고 있다. 하지만 부유체를 이용하여 수상에 입지하는 플로팅 건축물의 특성으로 인하여 기능, 용도 및 이용목적이 일반건축물과 동일하나 법적으로 다르게 취급되고 있으며 플로팅 건축물의 설계, 건설 및 이용 과정에서 다양한 문제가 발생되고 있다. 이러한 문제들은 최근 수요가 증가하고 있는 플로팅 건축물 활성화에 많은 제약이 되고 있다. 따라서 플로팅 건축물을 일반건축물과 같은 '건축물'로서 법적 지위를 인정받기 위해서는 "건축법"에서 정의하고 있는 '건축물' 및 '대지'에 대한 개념을 바탕으로 플로팅 건축물이 설치되는 수상공간에 대한 수상대지에 대한 개념 설정이 시급한 실정이다. 본 연구에서는 국내외 플로팅 건축물 법적용 사례를 바탕으로 일반건축물에 적용되는 대지의 개념으로 인하여 발생되는 플로팅 건축물의 법적 문제를 도출하고 이를 해결하기 위한 수상대지 개념 설정에 대한 방안을 모색하였다.

Main ground net of power plant is formed to protect human body from increase in potential gradient caused by grounding current during ground fault. Calculations during ground design are generally performed according to IEEE Std-80-2000 (Kepco Design Standard 2602). However, it is difficult to apply this Standard to water environment, and a grounding technology is required to secure grounding resistance of floating photovoltaic system. Therefore the aim of this paper is to investigate and analyze ground resistivity on the water surface and underwater of reservoir using Wenner 4-pin method, a general method of measuring ground resistivity. Also, grounding resistance of floating photovoltaic systems currently in operation was measured and analyzed using the voltage drop method suggested in the international standard (IEEE Std-81) to propose a grounding method for stable grounding of floating photovoltaic system. The resistivity at 1m below the surface of water ($126.3969[{\Omega}{\cdot}m]$) is mostly higher than resistivity at the river bed ($97.5713[{\Omega}{\cdot}m]$). Also the proposed grounding anchor method was determined as the most effective method of securing stable grounding resistance in floating photovoltaic systems and is expected to be utilized as a ground method for future floating photovoltaic generation systems.

Recently many different floating buildings are planed and constructed in the sea, river, etc. for active use of water spaces. But many problems are occurred in the process of floating building design, construction and management due to the inadequate legal system. This incomplete legal system has become one of the critical factors which are hampering the invigoration of floating buildings. Therefore this study is to suggest preliminary data and improvement directions through a case study with domestic and foreign examples of appropriate laws and law applications concerning floating buildings. As the results of this study the laws related to floating building have to be revised in the directions of qualifying legally floating building as 'building' but not 'ship', designating 'special zone' for floating building site, and applying the established 'building licensing procedure' to floating building also.

The purpose of this study is to classify the Korean precipitation regions on the basis of the characteristics of extratropical cyclonic precipitation. From now on, extratropical cyclone is called cyclone in short. By using factor analysis and Ward method in cluster analysis, precipitation regions on the basis of the characteristics of cyclonic precipitation are classified The principal data used in this study are daily precipitation records obtained from 60 weather stations of the Korea Meteorological Service during the ten years($1981{\sim}1990$), and weather charts published by the Japan Meteorological Agency. The results obtained in this study are summarized as follows: (1) In the factor analysis using 43 variables which have relation to the extratropical cyclonic precipitations, They are seven factors whose eigenvalues are above 1.0. This explains 86 percent of total amount. The first factor explains the characteristics of precipitation in the middle-west area and its contribution degree has the highest 10.9 percent. (2) According to the cluster analysis method of Ward, extratropical cyclonic precipitation regions are classified seven macro regions(such as Kyungki and North Youngseo, Youngdong and Ullungdo, Hoseo and South Youngseo, Honam and Northwest Chejudo, Southeast Chejudo, North Youngnam, and South Youngnam), 22 meso regions. (3) The characteristics of precipitation regions have relations to the path of cyclone, the direction of air inflow and the strike of mountain ranges. As the conclusion, the Central China Low brings much precipitation in the southern coast and southern area of Korea as moving to the northeastward. The North China Low moves eastward and brings much precipitation in the western area of the Taeback mountain ranges. The probability of extratropical cyclonic precipitation is the lowest in the inland of Yeongnam and the eastern coastal areas which belong to the rain shadow region. Namely, The seasonal and spatial characteristics of precipitation are closely associated with the path of cyclone and the direction of air inflow according to its passage, and the strike of mountain ranges.
