3차원 전기비저항 탐사법은 지하 전기비저항의 3차원적 분포 영상을 제공해 주므로 매우 효과적인 지반조사 방법 중의 하나이다. 본 연구에서는 붕락이 발생한 터널에 대하여 3차원 전기비저항 탐사를 수행하여 붕락의 원인으로 보이는 터널 주변의 파쇄대 및 석탄층의 발달 상황을 파악하고자 하였다. 이를 위하여 터널에 평행한 5개의 측선과, 수직한 11개의 측선에 대하여 2차원 전기비저항 탐사를 수행하고, 이들 자료를 통합하여 3차원 역산을 수행하였다. 역산 결과 얻어진 3차원 역산결과와 시추 자료를 종합하여 터널 붕락의 원인으로 해석되는 단층 파쇄대 및 탄층의 3차원적 분포 양상을 제시하였다. Three-dimensional (3D) resistivity method is an effective tool in the engineering site survey because it can provide a 3D resistivity distribution of the site. In this study, we tried to find out faults, fractures and coal seams that can cause the collapse of the tunnel. We carried out 2D resistivity survey along 5 parallel lines and 11 cross lines and merged all the apparent resistivity data for 3D inversion. Finally, from the 3D resistivity image and drilling data we presented the 3D distribution of faults, fractures and coal seams that are considered the main cause of the tunnel collapse.

Purpose The purpose of this study was carried out to determine the normal predictive equation of pulmonary function and related factors in Korean young adult(university students) using spirometer. Methods Measured the FVC (Forced Vital Capacity), FEV 1 (Forced Expiratory Volume in one second), ERV(expiratory reserve volume),VC(vital capacity) and surveyed body height, body weight. years. Study group was total I02(male 57, female 45)who were sampled from healthy young adults(Age is 18-28) at the shinsung university in dang gin city. Result The results of this study were summarized as follows: (I) FVC in male and female was 4.6±0.6 L. 3.3±OA L. FEV1 in male and female was 3.9±0.5 Land 2.7 ±OAL. (2) In correlation analysis, FVC, FEV1 showed positive correlation with body height body weight and negative correlation with age. (3) The prediction equation for FVC was 0.077 X height(cm)+0.020 X years +0.002 x weight-9.387 in male, and 0.030xheight(cm)+0.023xyears+0.006xweight-2A68in female. (4) The prediction equation for FEV1 was 0.055 x height( cm) -0.007 x years +0.003 x weight-5.855 in male, and 0.32 x height( cm) +0.007 x years -0.0 11 x weight (kg)-2.029 in female. Conclusion In conclusion, these results suggest that body height, body weight have significant association with pulmonary function. More research is need in the further for using these parameters in predictive equation.
