본 연구에서는 흙막이벽 설계시 널리 사용되고 있는 SUNEX 프로그램을 이용하여 Top-Down 공법이 적용된 지중연 속벽, 주열식 흙막이벽 (CIP벽, SCW벽)의 변형거동을 분석하였다. 해석프로그램에 Rankine의 토압(l857), Terzaghi and Peck의 토압(1967), Tschebotarioff의 토압(1973), 홍원표·윤중만의 토압(1995a)을 적용하여 흙막이벽의 수평변위를 예측하였다. 프로그램 해석결과, 흙막이벽의 수평변위량은 토압의 종류에 따라 큰 차이를 나타내고 있다. 홍원표·윤중만의 토압(I995a)을 적용하여 얻은 흙막이벽의 예측수평변위량이 실측수평변위량과 가장 유사하게 나타났다. 따라서 프로 그램 해석시 홍원표·윤중만의 경험토압(l995a)을 적용하면, Top-Down 공법이 적용된 흙막이벽의 변형거동을 비교적 정확히 예측할 수 있다. Abstract: The behaviors of a diaphragm wall and a contiguous pile wall such as CIP (Case-in-place pile) and SCW (Soil-cement wall), applied to the top-down construction method, were analyzed using the SUNEX program, which is widely used to design earth retaining walls. Four types of earth pressures, as described by Rankine (1857), Terzaghi and Peck (1967), Tchbotarioff (1973), and Hong and Yun (1995a), were applied to the analysis program to predict the lateral displacement of walls, The results show that the displacements of an earth retaining walls vary with the applied earth pressure. The predicted lateral displacement based on Hong & Yun`s (1995a) earth pressure is similar to the measured displacement. Therefore, the actual lateral displacement of an earth retaining wall, as applied to top-down construction method, can be accurately predicted by using an analysis program considering Hong and Yun`s (1995a) earth pressure.

본 연구에서는 지중연속벽 설계시 사용되는 범용 해석프로그램에 Rankin(1857)의 이론토압과 홍원표와 윤중만(1995a)의 경험 토압을 각각 적용하여 Top-Down 공법에 적용된 지중연속벽의 수평변위를 분석하였다. 그리고 이들 해석 프로그램에서 산정된 예측변위량과 지중경사계로 측정된 실측변위량을 비교 검토하였다. 현재 지중연속벽 설계에 적용되는 해석프로그램에는 Rankine의 토압이 주로 적용되고 있다. 검토결과, 지중연속벽의 예측수평변위는 적용되는 토압에 따라 상당히 큰 차이를 나타내고 있다. Rankine의 토압을 적용하여 산정된 예측수평변위 형상은 실측결과와 큰 차이를 보이고 있으며 벽체의 하부에서 예측치가 실측치보다 과다하게 산정되었다. 반면, 홍원표·윤중만의 토압을 적용하여 얻은 예측수평변위 형상과 최대수평변위 량은 실측결과와 유사하게 나타났다. 따라서 Top-Down 공법이 적용된 지중연속벽의 설계시 Rankine의 토압보다는 홍원표·윤중만의 경험토압을 적용하는 것이 적합함을 알 수 있다. The Rankine(1857)'s earth pressure and the Hong and Yun(1995a)'s earth pressure was applied to analyze the lateral displacement of diaphragm wall applied to the Top-Down construction method using the computer program, which is a common design program for diaphragm wall. The lateral displacement estimated by the computer program was compared with the lateral displacement measured by inclinometer. The Rankine's earth pressure has been widely used to design the diaphragm wall in the analysis of computer program. As the result of comparison, the lateral displacement of diaphragm wall was predicted differently according to the applied earth pressures. The behavior of lateral displacement predicted by the Rankine's earth pressure was different with displacement measured by inclinometer and the lateral displacement at the bottom part was overestimated. However, the lateral displacement predicted by the Hong and Yun's earth pressure is similar to the behavior and maximum value of real displacement. Therefore, the Hong and Yun's earth pressure is more suitable than the Rankine' earth pressure to design the diaphragm walls applied to the Top-Down Construction Method.

According to the growth of society, The risk events of construction project have been increased against the past because it is called for variety and complexity. So that, we are recognized, the risk identification and risk response strategy are very important things in the construction project. The existing studies about judicial precedent of claim deal with mainly proving of method which is to search the judicial precedent data, to make a decision of claim and to decide schedule of construction project. Because it dose not deal not deal with judicial precedent of clime as risk management view, however, it is not helpful so much to respond at the risk for the process of construction project to the owner and the contractor. The purpose of this study, therefore, is that it identifies the risk events and set up the risk response strategy, through analysis of judicial precedent of claim as a risk management view.

Objective : The purpose of this study was to find the relationship between the follow-up management status for medical problem to be treated and various characteristics of some workers at transportation business. Methods : A questionnaire survey was made toward 183 workers with medical problem(C and D2) among 945 examine in 1997. Results: Sixty four point five percent of surveyee received the examination result report and 40.5% were explained about the result 80.3% of surveyee answered that they knew the result of health examination. Most workers felt the necessity of the health examination, but 54.1% were dissatisfied with present health examination system and 66.7% pointed it out as nominal The rate of follow-up management for the medical problem was 62.8% By the multiple logistic regression the follow-up management rate for those who knew the health examination result were 2.98 times higher than those who didn't know the result (OR=2.98, 95% CI 1.41~6.29) The rate for those who perceived the medical problem already were 2.64 times higher than those who perceived the problem for the first time (OR=2.64, 95% CI 1.13~6.15). The rate for those who had subjective symptoms were 2.83 times higher than those who didn't have subjective symptoms. Conclusion : sixty two point eight percent of workers with medical problem performed the follow-up management and perception of health examination result, perception of the problem in the past and experience of subjective symptoms were related with the follow-up management.

Although peripheral polyneuropathy and retinal hemorrhage or microaneurism are early findings of carbon disulfide poisoning, the electroneuromyography for detecting neuropathy is very delicate and time consuming while the retinal microangiopathy is not frequent. And it is very hard to find the carbon disulfide poisoning at early stage by using current laboratory examinations such as liver function, renal function, serum cholesterol, blood pressure and electrocardiogram, which showed low positive predictive values for the peripheral neuropathy. Therefore those tests seer to be of little use for the early diagnosis of carbon disulfied poisoning. This study was conducted to find out the screening method of occupational carbon disulfide poisoning. For the purpose, a total of 108 spinners were selected randomly as subjects of the study from a viscose rayon industry in which more than 200 spinners were working The concentration of carbon disulfide in air of work-place, age and career of workers, hematologic exmination, blood chemistries, funduscopic examination, electrocardiography and neurologic examination including electroneuromyography were performed to evaluate the carbon disulfide poisoning. The result suggests that funduscopy for retinal microangiopathy audiometry and for hearing loss that show relatively high positive predictive values to carbon disulfide posoning be used to detect abnormal cases. In addition, it is desirable that workers who worked more than 10years would be examined by electroneuromyography for finding peripheral polyneuropathy and carbon disulfide poisoning.

일반적으로 LPA에서는 위상을 조정하기 위해 매우 긴 지연선을 필요로 한다. 지연성능은 고전력이나 저전력 모두에서 임의의 길이의 동축선로를 여러번의 과정을 거쳐 적용해봄으로써 구현된다. 그러나 동축선로형 지연선은 부피나 높은 삽입손실등의 제약이 많이 따른다. 본 논문에서는 마이크로스트립 형태의 지연선 대역통과 여파기를 설계하였고, 실험결과는 지연선여파기가 동축선로를 대신하여 LPA 시스템에 적용이 가능함을 보였다.

scene preservaton and taking a picture on case studies "Just imagine a murder scene." A police, a medical examiner and a court of justice all show different type of interests on their needs. A court of justice only cares about collecting evidence by preservation of the scene for the institution and support of a public action. The medical examiner also focuses on scene preservation in order to determine the cause of death. However, the police are pressured on arresting a criminal and perfect scene preservation at the same time. A crime is committed faster, intellectual and being specialized over a wider area these days. Further, criminals even try to delude the police by faking an actual spot ingeniously rather by just damaging or demolishing it. A little delay of police's action will make hard to find a criminal. Even if a criminal is arrested, it is still hard to find physical or human evidence, which results in necessary change in basic investigation process for the time being. The change should cover organization structure and HR management to catch up with ever-changing crime trend. As a crime occurs, most of police investigation proceeds in following order; scene preservation, on-the-spot inspection, scene investigation, criminal investigation, criminal arrest, on-site verification, forwarding to the prosecution. Among them, spot investigation is most essential and primal part. However, as stated before, the police overemphasize a criminal arrest, which makes 100% perfectly preserved scene almost impossible by overlooking its importance. Anybody related to crime scene, a victim, the bereaved, 119 firemen or first arrived officer, can be blamed for a scene preservation failure. But it's deplorable to say that the police are the one who damage a crime scene under the name of priority on rapid criminal arrest. They hardly care for securing evidence according to proper procedure. The problem caused by a primal scene preservation failure is not counted at all. The only concern they have is how rapidly they arrest a criminal. In the end, we need to come up with a systematic process that experts can gather evidence at perfectly preserved spot. Furthermore, we can get job done great by an effective communication between different parties; i.e. a police, a medical examiner and a court of justice. Hereby, this dissertation will discuss the right ways to preserve a crime scene through related case studies, along with general introduction of current scene preservation tools and taking pictures of spot.
