Electromagnetic and electric surveys were performed to reveal the deep structure of the Yangsan fault in the Bong-gye and Unyang areas, Kyeongnam Province, Korea. Especially, high-frequency magnetotelluric (HFMT) method of EM survey was mainly employed to study the deep subsurface configuration of Yangsan fault. HFMT survey was performed at 25 points of spacing 50 m, making 1.3 km survey line in Unyang area and 13 points of spacing 50 m, making 0.6 km survey line in Bong-gye area. Two 2-D cross-sections (Unyang and Bong-gye areas) were achieved as results. Electric survey by dipole-dipole array was performed to study the structure of shallow subsurface and compare the results with HFMT surveys. The results of HFMT and electric surveys show that Yangsan fault is a geologic boundary. It is very narrow and steep (about $80^{\circ}C$), and extends to 1~1.5 km depth.

본 논문은 군 조직을 대상으로 한 그간의 조사연구의 흐름을 살펴보고 군의 주요한 특징인 계급구조에 입각한 조사연구의 방향과 대안을 모색하였다. 군을 대상으로 한 조사연구는 제반조사환경의 제약으로 인해 조사연구 결과의 신뢰성을 확보하고 다양한 주제에 대한 함의를 제공하는 데 많은 제한이 있었다. 본 연구에서는 군 조사과정 및 결과에 중요하게 영향을 미치는 군의 위계적 계급구조의 특성을 입체적으로 파악한 뒤, 조사목적에 부합한 조사기획 및 분석방안을 도출하였다. 군 조사연구의 향후 개선방향은 군 계급구조의 특성을 고려한 군 조사기법의 정교화와 분석방법론의 다차원화로 구분하여 제시하였다 구체적으로 조사방법 및 조사과정을 보다 치밀하게 설계하여 조사를 실시하고 다양한 요인을 분석할 수 있는 다차원의 분석방법론을 개발, 적용하는 것이 필요함을 주장하였다.

Today, people are becoming more conscious regarding environmental-friendliness, and the society as a whole is becoming more aware of it. With such phenomenon, the purpose of this research is to examine how comfort and pleasantness of indoor environment influences when selecting a place for multi-cultural complex. To demonstrate the stated hypothesis, I have preceded the experiment by selecting the C multi-cultural complex of closed-type structure and T multi-cultural complex of open-type structure. The next step I took, in order to validate the public's awareness of environmental-friendliness, was conducting a survey. I then deducted a conclusion through comparison and analysis of experiment measures with survey result. As a result of the research, the experiment measures of each air, light, heat condition of the T multi-cultural complex of open-type structure had a higher measurement for the comfort and pleasantness than the C multi-cultural complex of closed-type structure. Moreover, after validating the consciousness of the public through the survey, they had a tendency preferring T multi-cultural complex of open-type structure over C multi-cultural complex of closed-type structure in terms of comfort and pleasantness. To summarize, it is proper to conclude that the criteria - comfort and pleasantness of indoor environment - has influenced significantly when it comes to selecting a multi-cultural complex through both the experiment and the survey result.

Green Frame is a column-beam system that uses composite precast concrete members. Previous studies have proven this system to be not only structurally safe, constructible, and economically feasible, but also environmentally-friendly. If the computerized program is used to estimate the quantity, the result of it shall be calculated much easily, quickly and exactly than manual estimation, because precast concrete members of Green Frame has standard size and connection method between it. Therefore, this study suggest quantity survey concept for column-beam structure comprised of composite precast concrete members. Hereafter, the quantity survey of Green Frame shall be much quickly and accurate, if the system would be made based on the result of this study.

이 연구에서는 전기비저항 탐사와 자기지전류(magnetotellurics, MT) 탐사를 이용하여 미얀마 중앙분지에 대한 탐사를 수행하였다. 미얀마에서는 지하구조의 전기비저항 구조로 해석한 연구가 미흡하여 심부까지 전기비저항을 제공해 주는 대표적인 탐사를 활용하여 지하구조를 분석하였다. 연구지역 지질은 셰일층과 사암층으로 구성된 해성퇴적층으로 지하의 전기비저항 값이 낮을 것으로 예상되었다. 이 연구는 (주)지오룩스에서 자체 개발한 전기비저항 탐사 장비(SmartRho)와 Phoenix사의 MTU-5A를 사용하여 연구지역에 대한 전기비저항 구조를 영상화하였다. 전기비저항 탐사와 MT 탐사는 지하 100 m까지는 수십ohm-m 미만의 전기비저항 구조를 보였다. 특히 MT 탐사 자료에서는 1 Hz 까지 TM, TE 모드가 거의 유사한 양상을 보인다. MT 탐사 2차원 역산 결과 150 ohm-m 이하의 낮은 전기비저항 구조를 나타냈고, 동서방향으로 전기비저항 구조가 나뉘는 것을 확인할 수 있었다. MT 탐사를 전기비저항 탐사와 인접한 위치에서 수행한 결과, 2차원 역산 결과가 유사한 전기비저항 값을 나타내는 것을 확인하였다. 향후 미얀마 중앙분지의 전기비저항 구조 연구를 위해서는 높은 전기전도도를 고려하여 전기비저항 탐사와 MT 탐사를 동시 수행하는 것이 효과적일 것으로 생각된다.

Electric and electromagnetic surveys were conducted to investigate the deep structure of the Ulsan fault in Ipsil area, south of Kyeongju. On this study, especially high-frequency magnetotelluric method of electromagnetic survey in the frequency range of 10~100,000 Hz was mainly employed to study the deep subsurface configuration. High-frequency MT survey was performed at 70 points of spacing 30~50 m, making 3.8 km survey line. As a survey result, a 2-km-depth 2-D cross-section was achieved. It shows vertical and horizontal subsurface variations of resistivity values. Near-surface layer having low resistivity value becomes thicker eastward up to 800m. There is a steep low resistivity zone in the west side of survey line, and there exists two low resistivity zones dipping west in the east side of survey line. Two low resistivity zones are interpreted to be related to major movement pattern of the Ulsan fault. This suggests that major fault lines are developed on both peripheral sides of the broad fault zone.

Most of ground investigations can be grasped geological distribution which like rock name, geological structure, soil condition, underwater condition, land slide, ground cave-in, ground collapse by geological survey. But geological survey is limited to part region geological structure, not wide region. Therefore, Image Processing Method must need to grasp wide region geological structure. The object of this research is presented analysis data of geotechnical engineering in first step investigation.

노동부에서 시행하는 $\ll$노동력수요동향조사$\gg$와 $\ll$임금구조기본통계조사$\gg$를 기초로 새로운 조사표와 조사방법의 도입으로 인한 영향을 분석하고 평가하는 간편한 통계적 방법을 제안한다. 두 조사 모두 매우 유사한 표집틀(sampling frame)과 표집법을 공유하고 있기 때문에 두 조사 중 어느 하나를 기준으로 다른 하나의 변동성을 측정할 수 있다. 여기서 제시하는 영향 평가는 연도별로 동일 범주에 속하는 두 독립적인 추계치들의 비를 기초로 진행되며 또한 새로운 조사의 도입 시점을 기준으로 전과 후로 분할된 비 데이터(ratio data)의 변동성을 통계적으로 비교하는 형식을 갖는다.

This study lays emphasis on the traditional houses of Hongsung, Poryoung which were hardly studied. The method of investigation is to grasp the type, the present condition, and the feature of the traditional houses through sample survey. This study lays emphasis on two myon of Hongsung, Poryoung retaining their original form relatively through sample survey. The houses of investigation subject involve the houses in which structure change is not big of repair and improved houses centering around houses confirmed things built in late-Chosun. The method of investigation is to consider survey, materials for research work, and literature and is to grasp the substance of houses through analysis of arrangement, plane, and structure.

We investigated subsurface structures of the Bransfield Basin, the Antarctic with AUH (Autonomous Underwater Hydrophne) which was designed to record abyssal T-waves generated from submarine earthquakes. The data obtained from a multi-channel seismic survey and an AUH were used for this study. A seismic reflection method was applied to the multi-channel seismic survey data in order to identify bathymetry and sedimentary structures, and the signals recorded in the AUH were used to obtain deep structures as we applied a seismic refraction method. Even though we couldn’t investigate deeper and detailed structure in study area because of lack of Airgun’s capacity, the AUH showed possibilities for being used for a marine seismic survey. From this experiment, we decided the upper and lower sediment layer velocities, detected irregular basement topography probably caused by submarine volcanic/magmatic activities, and retrieved the velocity of the basement and the depth of the sediment layer/basement boundary.
