In the die casting process, the flow of liquid metal has significant influence on the quality of casting products and die life. For the optimal process design of front housing part of aircon compressor, various analyses were performed in this study by using computer simulation code, MAGMAsoft. The simulation has been focused on the molten metal behaviors during the filling and solidification stages for the sound casting products. Two cases of casting design that have different types of gating system are considered in the analysis. The potential sites where the casting defects may occur is examined by computer simulation and an improved design process is proposed. Also the effect of partial squeeze on the quality of casting products is considered and the optimal time lag after filling process is determined. For the die-stability, the effect of operational parameters such as die temperature, heat cycle and spot cooling on the die life has also been analyzed.

The types of the multi-family housing are classified into the independent type, the mixed type and the public type by the approaching method. The characteristics of the independent type are the rear layout type(41.66%), the "ㅋ"type(56.14%), and the 2-room type(54.54%). In the mixed one, they are the front layout type(36.84%), the "ㄱ"type(42.10%), and the 1-room type(49.60%) and in the public one they are the front layout type(51.61%), the "ㅡ"type(41.99%). and the 1-room type(84.11%). It is found that the housing types are gradually tuned into the multi-family housing such as the independent house in the urban area due to changing the major independent type(82.60%) in the early of the 1990s to the public type(74.19%) in the end of the 1990s.

In this study, an examination and an analysis are carried out on the forms and components of the access spaces of hotel entrances from the front gate of five star hotels in Jejudo, Korea. The results of the study are as follows. In terms of the arrangement of the hotel, city hotels with a relatively narrow site area are influenced by site shape, while resort hotels with a relatively wide site area are affected by the environment. However, the location of the front gate was determined by the access road from the outside. Therefore, forms of access space are related to the front gate, which is governed by the access road, and to the entrance, which is determined by the hotel arrangement. If the front gate is in line with the hotel entrance, a straight line and the hotel are arranged vertically to the front gate(side arrangement) or the hotel is arranged horizontally to the front gate, but if the entrance is not in line with the front gate, it appears as a curved shape. However, those who use their own cars have a variety of choices for access route depending on the location of the parking lot.

The purpose of this study is to prove the correlations among various factors what determined to formation of front elevation proportion system through making an actual survey and investigating. According to the analysis of them, we make conclusions as follows; 1, On the assumption that average distance of 1Kan(間) is 1, the height of foundation is 0.21, the height of floor from foundation is 0.24, the height of normal column from floor is 0.85, the height of eaves from foundation is 1.10. 2. Southeast faced buildings are wider than southwest faced buildings in the distance of 1Kan (間) in the range of $110{sim}220mm$. The height of foundation and floor in the southeast faced buildings are higher than those in southwest faced buildings beside the height of normal column, eaves, high column in the southwest faced buildings are higher than those in southeast faced buildings. 3. As number of front Kan(間) increases, the distance of 1Kan(間) decrease and the height of eaves and high column(高柱) increases. This is cause of making a maximum needed inner space by increasing the distance of 1Kan(間). This is an wisdom for living from ancestors. 4. As number of Dori(道里) increases, the distances of 1Kan are nearly same but the height of eaves and high column(高柱) increases about 300mm, This is a natural result from an increasing of building scale. 5. The distance of 1Kan(間) in later 19C building is most wide but, the unit heights are minimal average values at year 1900 as a reference mark. After this, the height of normal column, eaves, high column are higher about $170{sim}330mm$. 6. The number of Kan in front elevation, Dori(道里), and direction of building have correlations each other in proportion system of traditional housing An-Chae with significant level, p<0.05.

In this study, the plane type of main building relics of unified Silla period house site which excavated in Gyeongju city after 1990s was classified and the architectural characteristic of them was investigated. The chronology of building relics in Silla capital city site was mostly known as 8-9th century, and by standard of column arrangement, the plane types of them could be classified as grid type, front veranda-grid type, outer column type. The outstanding characteristic of plane is wide span and open front veranda. In most relics the span were over 4 meters, and inner foundations for small post and strip foundation were found between columns. The front veranda added type buildings were composited of enclosed main room and open front veranda, and column arrangement of them dose not fall into line in most case. Thus it thought that the structures of enclosed main room and open front veranda were independent. The interior space of enclosed main room were divided two rooms by partition wall in some case. In this case, one room is enclosed by wall, and the other room has open front side. This plane is considered for the pleasant life in cold winter and hot summer.
