본 연구는 2003년부터 2004년에 걸쳐 대한광업진흥공사에서 수행한 지하수기초조사의 사업지역인 경남 밀양 및 경기 포천의 지역별 충적층 두께 분포 특성을 파악하기 위하여 전기비저항 수직탐사(슐럼버져 배열)에 의해 획득된 충적층 심도 자료에 대하여 지구통계학적 기법인 정규크리깅을 적용하였다. 물리탐사 자료의 적용성 검증을 위하여 물리탐사 자료와 시추공 자료의 상관성분석을 실시하였다. 정규크리깅에 의해 충적층 분포를 이미지화한 결과, 지형이나 유역에 따라 충적층 심도분포가 합리적으로 묘사된 것으로 나타났으며, 따라서, 충적층 심도 분포 파악에 있어서 전기비저항 수직탐사 자료에 의해서도 만족할만한 수준의 결과를 얻는 것이 가능한 것으로 판단된다. In this study, vertical electrical sounding (VES) data and ordinary kriging are used to identify the alluvial depth of each area that Korea Resources Corporation (KORES) conducted groundwater survey at Miryang area in Gyeongsangnam-do and Pocheon area in Gyeonggi-do from 2003 to 2004. To verify the applicability of VES data to ordianry kriging, regression analysis of VES data versus drillhole data is conducted. Comparing the alluvial depth distributions using ordinary kriging with existing drillhole data, the result shows that the depth distributions are reasonably depicted along with the topography and the basin. So, the ordinary kriging of VES data is useful to identify the alluvial depth distributions.

Fuel used in the steel metallurgy industry is stored in huge stage systems called SILO. Fuel is released by RDM (Rotary Discharge Machine), at the place of utilization. RDM is located in the Silo, and is constituted of a main frame, driving part, discharging part and control part. RDM is combined to a direct motion on the rail in tunnel, having a rotary motion enabled by a motor. In this paper, we calculate the theoretical discharging capacity of RDM to confirm the correlation between design element and discharging capacity of RDM. Also, through structure analysis, we confirm the vulnerable point of RDM when it discharges the storage materials. We hope to apply these results to design a more efficient RDM.

Objectives : The purpose of this study is to report the effect of traditional Oriental hair care products on inhibition of extensive alopecia areata. Methods : We have experienced a 29-year-old woman with extensive alopecia areata to get worse quickly. The patient was treated by acupuncture and traditional oriental hair care products in 9 months. We used HRV(Heart Rate Variability), APG(Accelerated Photoplethysmograpy) and SALT(Severity of alopecia tool) scale for the assessment of alopecia areata and her physical condition. Results & Conclusions : Her hair loss and physical condition was completely improved.

The purpose of this study was to analyze the wind vibration of super-tall buildings and to diminish the vibration of wind load. The tapers-twisters-damper structural design absorbs wind forces safely and efficiently and transfer them to the foundations in order to avoid structural collapse. The model height is 276m which located in Changwon. The results of this study were as follows; the opposing wind-load of upward tower was higher than opposing wind-load of standardized tower.

강원도 삼척시 가곡면과 태백시 철암동에 위치한 가곡광산은 묘봉층 및 풍촌층내의 석회암과 화강반암의 접촉부에 배태된 접촉교대광산이다. 본 광산에서 지구물리탐사는 갱내 및 광산 주변부에 광화대의 부존 여부와 그 연장선을 파악하기 위하여 갱구 부근에서 자력탐사, 갱내에서 전기비저항 탐사 및 갱도-갱도 전기비저항 토모그래피탐사를 실시하였다. 자력탐사는 광화대의 영향으로 인한 이상대가 확연히 나타나지 않았지만, 전기비저항 탐사 및 토모그래피 탐사는 광화대에 대한 영상이 성공적으로 반영되었는데, 이는 본 연구지역에 존재하는 N50°W계의 단층 연장선과 관련된 것으로 해석되어진다. The Gagok mine is a contact metasomatic deposit, located at Gagok-myeon, Samcheok city and Cheoram-dong, Taebaek city, Gangwon province. The deposit lies within the limestone of Myobong and Pungchon formations, and exists the contact of intrusive granite porphyry. In order to determine the direction and extension of mineralization in the gallery and around the entrance of the ore deposit, we used the ground magnetic survey, the direct current (dc) resistivity survey using dipole-dipole array, and resistivity tomography survey. The ground magnetic survey did not detect the anomalous zone due to ore deposit, while the dc resistivity survey and resistivity tomography survey were successful in delineating the anomalous zone related to the extension of fault toward N50°W.
