The road surface scripture season must be interpreted with hitherto whole aspect line scripture season different. TRAM (street cars) it respects an operation it stands and back must be operated the bus which runs place and riding grade different public transportation means and to be mixed. With the numerous crossroads zebra crossing and the coat platform must operate back. The role of the operation article most is important. It undergoes the influence of traffic signal specially directly. It considers each facility etc. of the road and must construct a proper equipment in him with connection method of the signal system which it follows in the middle urethra. Must secure the fixed time characteristic of the operation which road surface scripture season is efficient and expression speed and operation. In order the [le] according to interface plan with traffic signal it does to consider a traffic signal first of all. This the research of operation provision is necessary.

Purpose - This thesis is to develop a management plan and checklist by analyzing the prevention of accidents in advance by presenting the management plan for the major causes of railway accidents. Research design, data and methodology - In recent 5 years, we have analyzed the cases of railway accident, presented the management plan for the accident, and made a practical safety checklist focusing on the main measures according to the management plan. Results - The analysis of the cases of near-railway accidents suggests more concrete and practical safety management measures because the similar accidents are continuously occurring due to formal safety management. Conclusions - It is more valuable to apply to the adjacent construction of the railway line by creating a detailed checklist based on cases rather than the existing checklist. This study is written only as a human factor. For future real - time safety management, it is necessary to study more precisely cause analysis and safety equipment as a big data - based safety control system for more systematic safety management.

In order to use and manage the building energy efficiently, it is necessary to minimize building energy consumptions, and establish operation plans of various equipment. The maximum heating and cooling load calculation is an essential way in various equipment selections, and the annual building load calculation is used in forecasting & evaluating the LCC required for operation plan. In this study, noting that the annual building load changes depending on outside temperature around year, we propose a predicting method of annual building load. By using the $4^{th}$ polynomial function that have two double radix and a feature the $f(x)=a^4$ in x = 0 condition, we can calculate annual building load very easily only with the two result (maximum heating and cooling load) and a minimum parameters.

This study deals with the procedure of safety improvement, productivity increase ,and tact-time reduction through setting up the system about preventive maintenance. Actually, it is hard to establish and carry out preventive maintenance, even though we recognize the importance of the system concerning time, cost, labor, and so forth. In this study in the viewpoint of cost we are for achieving maximum efficiency by change and reduction of planning process adapted to the special work group. At first we briefly will mention the kind ,the necessity ,and the concept of preventive maintenance ,and then divide the equipment used in the assembly line into the two whether it is necessary or not by way of estimating the breakdown loss ,comparing with general establishment of preventive maintenance and modifying it to the case. At the second step we will establish the operation system of plan management related to production and quality in the special case. Check period and category will be set by dividing the assembly equipment into LCL and Focus in the third step. The forth step will contain the operation procedure in detail. And then we must make check and repair record periodically. Finally, on the basis of the record the selection of checking of significance will be conducted. This results in safety improvement, tact time reduction, and productivity improvement.

본 연구에서는 컴퓨터 시뮬레이션을 NATM공법 지하철 터널에 적용하여 적절한 장비조합과 작업 시간을 산출할 수 있는 모델을 구축하는 것을 목적으로 하며, 굴착하는 터널길이 즉, 증가되는 갱내 운반거리를 모델에 반영함으로써 현실에 가까운 모델을 구축하였다. 본 연구를 통해 구축된 모델은 지하철 터널공사의 제한 조건을 고려한 합리적인 의사결정도구로 사용하고자 하며, 터널공사 중 장비운용계획에 의한 작업 효율성에 가장 영향이 크다고 판단되는 버력처리 공정을 중심으로 시뮬레이션 기법 적용의 효과를 분석한다. 시뮬레이션 적용에 의한 효과 분석은 기존 관행에 의해 수립된 공사계획의 문제점을 알아보고, 굴착에 따른 갱내 운반거리와 투입되는 덤프트럭의 수의 변화를 통해 작업시간과 장비의 효율을 알아보았다.
