The semiconductor industry is highly capital and technology intensive. Technology advancement on circuit design and process improvement requires chip makers continuously to invest a new fabrication facility that costs more than 3 billion US dollars. Especially major semiconductor companies recently started to discuss 450mm fabrication substituting existing 300mm fabrication of which facilities were initiated to build in 1998. If the plan is consolidated, the yield of 450mm facility would be more than doubled compared to existing 300mm facility. In steps of this important investment, facility layout has been acknowledged as one of the most important factors to be competitive in the market. This research proposes a new concept of semiconductor facility layout using hexagonal floor plan and its compatible material flow pattern. The main objective of this proposal is to improve the productivity of the unified layout that has been popularly used to build existing facilities. In this research, practical characteristics of the semiconductor fabrication are taken into account to develop a new layout alternative based on the analysis of Chung and Tanchoco (2009). The performance of the proposed layout alternative is analyzed using computer simulation and the results show that the new layout alternative outperforms the existing layout alternative, unified layout. However, a few questions on space efficiency to the new alternative were raised in communication with industry practitioners. These questions are left for a future study.

The purpose of this paper is to reconstruct the original floor plan and wall design of Seokbulsa Grotto in Kyungju; commonly known as 'Seokguram'. The paper presents an array of dimensional studies of the existing Seokguram to examine its architectural form, and infers the original floor plan and wall design of Seokbulsa Grotto. Seokbulsa Grotto is designed as a system of 'coherent modules' and was constructed using the dry stone method, which interlocks large stone modules into a whole that becomes the load-bearing structure itself. The design principles governing Seokbulsa Grotto are the spatial axis of symmetry, modular coordination, and the layout grid of a quarter Tang-Ruler(TR: 唐尺). Dimensional studies were conducted with these governing principles in mind and concludes the following about the original floor plan design. In the main chamber, Ansang-stone's radius is 12 TR, and Flagstone's radius is 12¼ TR. In the front chamber, the width between the two Ansang-stones facing each other is 22 TR and the longitudinal space depth is 12 TR, while the width between the two Flagstones facing each other is 22½ TR and Flagstone's depth is 12 TR. In the passageway, the width between the two Ansang-stones facing each other is 11½ TR and longitudinal space depth is 9 TR, while the width between the two Flagstones facing each other is 12 TR and Flagstone's depth is 7¾ TR. The distance from the center to the entrance line of the main chamber is 10½ TR. Therefore, the total longitudinal length of the Grotto is 43½ TR at the level of the Ansang-stones, and 44 TR at the level of the Flagstones.

The most commonly used method for space management in the industry is development of site plans. These plans outline how to manage material deliveries, staging areas, and crane locations for construction sites in suburban area but not in congested urban areas. This study focuses on how to efficiently manage space for construction facilities on high-rise buildings in congested urban areas where normally space for facilities around a building footprint is not available. The limitations of available horizontal space create a need to explore vertical expansion of facilities. This raises new aspects of vertical facility handling and flow that need to be considered in the facility design problem. The construction facilities layout plan method provides layout planners with a valuable technique to develop efficient sequences of work that optimally defines how to efficiently utilize the construction facilities and minimize the travel of specific facilities effort on multiple-floor buildings. A genetic algorithm-based heuristic will be presented for generating block layouts for multiple-floor la)rout problems.

The study on Buddhism architecture in early Joseon dynasty was inactive. The period of King Sejo is important for studying the trend of Buddhism architecture in early Joseon, that was transmitted from the end of Goryeo dynasty, but it was difficult to know its exact situation due to lack of related records. The records were all written by Kim Su-ohn, which are Wongaksabi' 'Sangwonsajungchanggi' 'Bongseonsagi 'Geonginsajungchanggi'. The main hall was mainly second floor and there were necessarily annexed buildings at the right and left of the main hall. So the plane figure of $\Box\Box\Box$ was shown. It was a main stream for main hall. This layout may be referred to search for the origin of the layout in courtyard based structure(中庭形) in the late Joseon dynasty. Most of temples had 3 gates. Some part of horizontal corridor was used as 2 gates and the outer gate, far from main hall, was without corridor. The gate leading to front yard of main hall was called front gate, the next middle gate and the outer gate was Oisamun(外沙門) or Samun(沙門). Im most of the temples, people could enter into the front yard through pavilion which had the function of bell tower. The pavilions were located between front gate and first corridor. It is thought that this layout of the place for making bean curd outside the temple area will contribute to different studies on temples making bean cure in the future. The records about temples's foundation studied above are a little different between temples, but have more similarities. There common denominators represent the architecture tendency of Buddhist temples in the related period. It is thought that such a tendency was also shown on architecture of other temples during the reign of King Sejo as well as Buddhist temples.

The purpose of this study is to clarify the actual condition of the layout and floor planning of elementary schools for the 7th education curriculum. This article discuses about the basic characteristics of the plan composition and the outdoor spaces of 35 elementary schools in Gyeongnam prefecture. The results of this study are summarized as follows; 1) To respond to the 7th educational curriculum, unit classrooms need to be expanded or space for a multi-purpose room needs to be secured to serve the following purposes: the operation of educational program by the level and offering of unified Subjects. overall, elementary schools need to seek ways to deal with problems associated with space composition, types of classrooms, and changes in the number of classrooms so that the 7th Educational curriculum can be carried out smoothly. 2) Different from the past, various plan types are available nowadays. Even in case of schools with the same class size, their areas were different by 130 percentages or higher. Therefore, practicality needs to be more focused than facility standards in order for the school to cope with changes in future educational environment. 3) When designing the elementary school in the future, more space needs to be assigned for learning by expanding facilities - special purpose classrooms and supporting facilities - to accommodate students' various learning activities. In addition, faculty facilities need to be rearranged to promote research and development as well as to ensure the operation of the educational program. And, resident facilities that consider the close connection with the local community need to be rearranged in an efficient manner as well.

This thesis attempts to investigate and analyse the architectural characteristics of catholic churches in Gangwon province built in the 1950s. Catholic churches built at that time in Korea had many similarities basically since they were supported by UN forces after the Korean War and were established by priests connected to the Missionary Society of St. Columban. The results of study are as follows. In location, Except one catholic church, the catholic churches preferred low and gentle hill. In layout axis, catholic churches at Youngseo area preferred the north-south layout axis, whereas those at Youngdong favor the east-west layout axis. In approach, most of catholic churches around the Youngseo and Youngdong areas preferred entering the front entrance with a bell tower, whereas three of them at Youngdong did entering the front entrance with a bell tower around the rear corner. In floor plan, catholic churches at Youngseo preferred symmetry, whereas those at Youngdong preferred asymmetry. And every floor plan of catholic churches is rectangular type with transepts except one semicircular type. In apse shape, catholic churches in the Youngseo area preferred non-extruded types like a straight wall, whereas those in Youngdong have extruded types. Every catholic churches have no crypt under ground except one at Gangreung. Except one at Sokcho, every catholic church in this study has choir space in half story.

Purpose: Emergency room(ER) is the first place to enter a hospital where patients who might have been infected with contagious disease. Therefore, ER should be designed with infection control in mind. Researchers examined hospital ER layouts to identify layout design that support infection control. Methods: This study analyzed the hospital ER layout of Korean and other hospitals abroad. Researchers focused on route of incoming patients who potentially have infectious disease. Crossing of this route with other routes such as for imaging and testing should be avoided for infection control. Results: There were certain hospital ERs with better control of infection related incidents. ER floor plan layout is analyzed about allocation of key functions with movement routes for each role such as patients and medical staff in mind. To identify layout strategies for ER functions researchers simplified the routes in ER into diagrams. Layout options show that bypassing infection suspected routes over other routes is possible. Implications: Hospitals can control infection easier when they adopt strategic ER layout identified in this study.

The purpose of this study is to investigate the changes of architectural characteristics of the rural houses in Jeju area for the last half a century. 72 houses in eight villages, which have been spontaneously renovated or added, were chosen as the rersearch samples. The subjects were classified into three groups-traditional, modernized, and contemporary houses-mainly by their construction years. Based upon these classification, the factors of change and continuation in building layout and spatial composition of dwellings have been investigated. As the results, Jeju rural houses show the tendency of the various and rapid changes in overall shape and spatial composition, but the traditional concepts of composition in plan has been maintained. Especially, the open structure of three-folded houses and the utilization of traditional floor system have been maintained as major design concepts to compose a house.
