While the environment of usage of information and technology is getting stable and technology is being developed more deeply due to the globalization, making information, standardization, in order to make a fast response to the new industry strategy and business environment, mutual communication and management of correct and fast information are focused on as fundamental elements of keeping competitive power. Accordingly strategic development of urban transit operation organization, storage of information technology of urban railroad, and buildup of standard information infra are very important, so that computerized information system has been built up standardizing efficient maintenance framework of urban transit facilities. To maintain these facilities efficiently, storing the real-time information by standardizing the maintenance organization and building up computerized information system are very important with management of information history of existing maintenance work. Therefore, for the efficient maintenance of civil facilities among urban transit facilities, standardized facilities classification and definition of management elements, and the plan of designing and building standardized database about civil facilities through standardizing technology resources are described in this paper.

The Purpose of this study is to analyze the investigation of consumer's consciousness for Han-Ok construction of community facilities in an apartment housing. The contents of this study were largely composed of two parts; First was about concept and type of 'New Han-Ok type' public building. Second was about consciousness for Han-Ok construction of community facilities in an apartment housing. The result to this study is as following: 1) the concept of 'New Han-Ok type' public building should not only be defined in terms of cultural property or Han-Ok experience facilities but daily life and practical community. 2) the consciousness for Han-Ok construction of community facilities in an apartment housing was recognized affirmatively more than 75.9%. 3) the strengths of 'New Han-Ok type' public building was as following: daycare centers & small libraries & management office-use of eco materials, senior centers-traditional maintenance, community center-ease of daylight and ventilation. 4) Weaknesses of 'New Han-Ok type' public building was as following: daycare centers-security problem, senior centers-inconvenience of space, community facilities-inconvenience of facilities, small libraries-lack of storage space, management office-inconvenience of moving line. The conscious research for 'New Han-Ok type' public building should succeed for vitalizing for Han-Ok.

Recently problems of soil and groundwater contamination occur in major construction sites of highway, dam and railways. Contaminants of oil fuels are also detected in the former fuel storage facilities of railroad station and army troops of transportation, etc. These facilities are planned as the sites of commercial infrastructures after restoration from pollutants by the law of soil environment conservation of Korea. In this manuscript, the contents of soil environment conservation law including soil assessment and restoration technology are introduced. Recent changes of soil environment area are also analyzed.

과거와 달리 21세기의 도래로 주변에 많은 전산화 및 정보화작업이 이루어지면서 데이터 트래픽이 폭발적으로 증가하고, 정보 통신망은 이를 수용하기 위해서 전반적인 큰 변화를 겪어 왔으며 현재도 겪고 있는 중이다. 또한 정보의 중요성을 인식하면서 부터 많은 기업들이나 개인들이 정보의 손실을 의식하고 있으며 정보를 안전하게 저장하고 원활하게 활용할 수 있는 방법을 모색하게 되면서 SAN(Storage Area Network)에 대한 의존도가 높아지게 되었다. 본 고는 현재 사용도 가 높아지고 있는 Fibre Channel을 이용한 SAN전송로의 구성 및 동향에 대하여 살펴본다.

This paper proposes a method for designing stacking warehouses of pyramid type which can be found in storage rooms for steel coils, paper rolls, and drums for oils. Formulas were derived for estimating the expected travel time of cranes and the expected time for rehandling activities. Based on the derived formulas, this study derives the cost function for determining the optimal numbers of rows, bays, tiers of stacks under the condition that the requirement for storage space is satisfied. Numerical examples were given.

Natural gas as a clean fuel of the world demand for the trend is gradually increasing demand for clean energy in the country and there is growing interest. Therefore, LNG storage tanks and related facilities in the country of the importance of leading a community-based facility has emerged. So common sense that an earthquake with a seismic isolation device LNG storage tank similar to the actual behavior of the analytical model which can describe the development and construction of storage tanks to enhance the safety and economic design techniques need to be developed. In this study, a base isolation system, seismic analysis procedure of LNG storage tanks, and Triple-FPB developed a mathematical model of the present crystallized and complexity factors to the sum over histories model simplifies the complex behavior of the LNG storage tank with base isolation system how to interpret the seismic isolation is proposed.

In recent years there has been a steady increase in geoenvironmental engineering projects where geotechnical engineering has been combined with environmental concerns. Many of these projects involve some investigation of contaminant in the ground. There are many techniques such as geophysical, drilling, sampling, md pushing techniques for investigation of contaminated ground. The most rapidly developing site characterization techniques for geoenvironmental purposes involve direct push technology, that is, penetration tests. The purpose of this study investigated underground oil storage tanks(USTs) using the envi-cone penetrometer system. The electrical resistivity sensor, pH sensor, ORP sensor, and thermometer are installed in envi-cone penetrometer system. This envi-cone penetrometer system provides a continuous profile of measurements, and it is rapid, repeatable, reliable and cost effective for investigation of contaminated ground surrounding the underground oil storage tanks.

The ability to determine the optimal frequencies and offsets for independent and unrestricted ordering cycles for multiple items can be very valuable for managing storage capacity constrained facilities in a supply chain. The complexity of this problem has resulted in researchers focusing on more tractable surrogate problems that are special cases of the base problem. Murthy et al. (European Journal of Operation Research 2003) developed insights leading to solution of the original problem and present a heuristic for offsetting independent and unrestricted ordering cycles for items to minimize their joint storage requirements. However, their study cannot find optimal solution due to the Greedy Heuristic solution procedure. In this paper, we present a complete procedure to find the optimal solution for the model with a integer programming optimization approach and genetic algorithm. Numerical examples are included to compare each model with that of Murthy et at. Research of this type may prove useful in solving the more general problem of selecting order policies to minimize combined holding, ordering, and storage costs.
