터널을 굴착하면서 발생하는 여굴은 터널공사에서 공사비 및 안정성에 지대한 영향을 미치게 된다. 여굴은 지지구조를 정확하게 예측하지 못하거나, 적정 장약량을 산정하지 못하는 등 다양한 원인으로 발생한다. 따라서 본 연구에서는 철도터널 바닥부 기초 및 주변지반을 모사한 후 3가지 유형의 여굴채움 재료를 이용하고 시공단계에 따른 안정성 검토를 수행하였다. 여굴채움 재료별 해석결과 모두 정적안정성이 확보된 것으로 해석되었다. Overbreak is an inevitable during tunnel excavation. It significantly affects tunnel construction cost and safety. The overbreak occurs due to incorrect expectations to the geologic structures, excessive charge or strength of explosives, etc. In this study, Numerical analyses were performed to evaluate Stability in three overbreak filling material using a model railway tunnel bottom ground around the foundation. Overbreak filling material analysis results showed that the stability is secured. Additional research for the dynamic stability of tunnels train driving is considered necessary.

This study was conduced to provide a method of tending practices for natural mixed stands, which have a possibility of inducing to selection cutting stand based on the analysis of stand structures. For this, first, diameter distribution for a balanced selection cutting stand was predicted using Q theory applied to natural stands. The method of estimating diminution ratio coefficient Q is presented. The possible tending practice method which could be adopted to natural stands is discussed based on two different diameter distributions and side conditions.

사람의 뇌에서 노피민분비 유노단백질(DARP)의 존재 및 분포를 밝히기 위하여 면역조직화학을 시행하였다. DARP의 분포는 간뇌의 뇌설옆핵과 시상그물핵에서 중뇌에서는 흑색질의 치밀부위와 아리둔덕의 중심핵에서, 교뇌에서는 내측전정핵, 내측세로핵, 외측쐐기핵, 아래침샘핵, 고립로핵에서, 인수에서는 내측망상핵에서 양성반응이 관찰되였으며 tyrosine hvdroxylase(TH)를 표식자로 하여 이미 보고된 바 있는 caiecholamine 양성세표 및 양성신경섬유의 분포와 매우 유사한 분포를 하고 있었다. 이러한 두 물질의 분포의 유사성은 DARP가 catecholamine 분비세포를 조설한다는 사실을 다시 한번 입증해 주고 있다.

The rectifier for Electric railway is one of the most important facilities in DC urban railway which converts power from KEPCO(AC 22.9kV) to the electric rail car(DC 1.5kV), therefore it should be managed as the best condition for the drive. There are several things to cause performance degradation and deterioration of parts such as pollutants occurred by it established under the ground such as dust or foreign substances, rapid changes of driving current, and pyrogen which put the rectifier for Electric railway in malfunction. On the flow of time, the rectifier for Electric railway is causing a malfunction or failure which drive electric rail car in operations as well as loss of life. In this research we try to find the way of removing the various components of mal-functions in the performance of the rectifier for Electric railway by Over-Haul and reform itself, which gives us to get the chance investment of the reduction, the reliability of power supply to the electric rail car.

In comparison with Over-head electric power line, Underground electric power line system has benefits such as power supply and city environment beautification, so 22.9㎸ distribution electric power cable of KEPCO is installed around the metropolis highways. Also, the electric power cable that Urban railroad is using is stretched in a narrow underground space by using pipelines or troughs. The electric power blackout paralyzes the function of subway in operational state as well as brings about social confusion. Furthermore, the weakness of XLPE cable, as a result of water tree thermal phenomenon, real life span compared with life expectancy is by far a long way and water tree thermal preventive measure has been constantly increasing up to now. Therefore, the necessity of the failure prevention of underground electric power cable is urgently needed and the reliability improvement of power supply is on gradual increase. A study shows that more than 50% of underground cable failure are caused by water tree defect, in order to avoid the damage of electric power cable that take places under operation by adding high voltage to the electric power cable, the insulation efficiency is measured by using the method of IRC analysis that can be measured in operational state, and we try to find the instance study on Silicone Fluid/XL construction method reinforced insulation efficiency by preventing water penetration within cable and get rid of penetrated water to control the water tree thermal of electric power cable.
