The lithography system installed inside precision industry's (e.g. TFT-LCD) production factories are increasing in size, thereby increasing its dynamic load along with it. Such condition causes vibration within the area where the system is installed, which then negatively affects the production line to produce defective products. To prevent this type of situation, the facilities should adopt dynamic design that considers the lithography system's dynamic load. This study predicts the maximum value allowed for dynamic stiffness (which is a ratio of vibration response against a single unit of the dynamic load) of the lithography system and explains the result of its application on actual structures inside the facilities.

Abnormal climate events are occurring frequently around the world. In particular, cold waves and heavy snow lead to damage and deterioration of facilities, which can cause loss of life or property damage, such as shortening the lifespan of facilities. Therefore, it is very important to prepare an appropriate maintenance system and to establish a strategy to cope with abnormal weather conditions. In this study, laboratory freezing experiments were performed to analyze the freeze-thaw characteristics affecting the tunnel concrete lining, and heat flow analysis was carried out based on the test results. Based on these experimental and theoretical analysis results, quantitative freeze-thaw evaluation criteria for tunnel concrete linings were proposed.

PURPOSES : Lots of criticism such as over/duplication investment, inconsistency of the policies among local governments and national plans etc. has been aroused due to the policy of supply-driven construction for transportation facilities. Recently, according to the environmental-friendly transportation policy, the investment of railroad has been expanded gradually, however the duplication with existing road facility makes it difficult to construct railroad. Thus it is necessary to evaluate the interrelationship between new project and existing facilities in the planning stage. However the method and the criteria for analyzing the duplication and over-investment of projects are not established in the manual, thus the feasibility of these projects are carried out from the economic point of view. METHODS: First, It reviewed about interrelationship criteria(domestic, overseas) and proposed implications and this study directions. Next, It developed the methods of evaluating independency, competitiveness and complementarity. RESULTS : In this study, the methods of evaluating independency, competitiveness and complementarity etc. are suggested to analyze the interrelationship between transportation facilities. The case study was carried out to examine the applicability of the methods. CONCLUSIONS: The methods raise rationality of decision-making compared to existing one. In the future, these methods are introduced into the manual of pre-feasibility study and feasibility study, more efficient decision-making and investment are expected.

Ministry of Education and Human Resources presented on December, 2006, 'Alternative school establishment and operation regulation' of contents that can be recognized attainments in scholarship because is authorized if alternative schools fulfill fixed condition. Even though, one time, it was true that several opinions which try to limit to adaptation school of person disqualified for school, thus, various discussion and efforts that specialized school for alternative education does to grow are appearing. However, the expectation which a lot of non authorized schools will apply is not so high because specialized school for alternative education will be controlled in free curriculum and school operation that have been administered and can not be guaranteed school's sell-regulation if acquire legal authorization. Under such social and educational background I surveyed present condition, law, system, literature investigation of existing study, Japanese system and example and authorized two sample specification schools etc. through 'A Basic Study on the Optimum Facilities Criteria Modeling of Regional Specialized Schools for Alternative Education(2006. 10)'. This study was preceded the succession and I visited 17 schools that permit investigation opening of schools among 29 that is authorized until present. So I try to find out architectural planning criteria to activate specialized school for alternative education more through analyzing school's general present condition, establishment idea, operation and specialized education plan, facilities present condition and characteristic.

Because of the increasing demand for day care centers, The Korean government has enforced childcare accreditation. The government has created the evaluation certification system for child care facilities. But the system includes variable items, and the physical rules are not sufficient for ensuring security and quality amenities. So this study, through literature search, examined the rules of Child Care Centers in the U.S. and compared them with those in Korea focusing on the provision of security and amenities. The standards found in 4 U.S. states were investigated, and the results are as follows. The rule pertaining to the size of indoor activity spaces in C.C.C. allows the spaces to be smaller in Korea than in the U.S. There is no specific criterion for infants and toddlers in our standard. When comparing the standards of Korea with those of the United States, Korea's standards do not state specific rules about child care facilities such as indoor furniture, finishes and space planning. Additionally, the binding force ensuring compliance with the standards of physical facilities is weak. Thus, the ratings of child care standards for the physical environment should be presented in detail. And if a center does not comply with the criteria, stronger penalties will have to be imposed.

The purpose of this study is to actualize the planning method of the shared community space (SCS). For this, it analyzed the residents' needs for the SCS and grasped the composition system of the needs and estimated the factors considered in the planning of the SCS. This study focused on seeking out the user-oriented design criteria for the planning of the SCS. The results of this study are as follows: First, as the results subdividing the residents' needs to understand the various requirements for the SCS, the composition system was classified into the fundamental SCS and the individual SCS. The fundamental SCS's to be considered as basic facilities in the planning of the multi-family housing complex, and the individual SCS to be more suited to a particular group. Second, regarding the investigation of detail guidelines in the SCS planning, it was found that there was a difference in the considered factors and the preferred locations according to the kinds of each SCS, the types of facilities, the main users of facilities, and the contents of activities available in the facilities.

Design-build is expanding gradually in large construction projects over 10billion won, and continue to work in health care facilities is increasing in this way. This constructional method in health care facilities, despite the many advantages, many problems caused by design changes are being raised. Raises the question of design changes on the side of construction contract, such as approval systems have been studied in the field of construction. The purpose of this study design in aspects of architectural planning on changing the grasp of the issues outlined in the ITB and bid evaluation criteria through consideration of the basic plan for improvement guidelines and evaluation criteria is presented. In conclusion, Design build, according to the presence of existing users are more likely to lead to design changes. Thus, hospital architecture, depending on how it is considered that constructional methods. And evaluation items of ITB(Invitation To Bidder) for a large part of the change in the variables evaluated in the hospital building is not suitable for the design build. Instead, the overall shape of the building and department, unit type and size, vertical and horizontal parts of the circulation system in the shape of the building that does not change in structure and etc should be considered for evaluation.

This study suggests several ways to improve the railroad facilities in the urban areas so as to maintain the urban railroad facilities and minimize their adverse impact on the roads around the facilities. Environmental problems such as noise and vibration can be minimized by constructing soundproofing walls and improving railway and train systems. To reduce the traffic congestion at the railroad crossings, current at-grade crossings should be changed to separated crossings. Moreover, the criteria by where railroad crossings are located should be revised. In the long term, the land use development for the railroad station and the surrounding areas needs to be changed. Several case studies of Japan's and France's major cities show the potential of successfully integrating the development of railroad facilities and their surrounding areas. In addition, there is a need to .consider institutional aspects, to improve the railroad facilities in the urban areas and to allow the integrated development of the railroad facilities and the surrounding areas.
