Plastic pipes Wrapped with synthetic filter are recently used for drainage or Collecting of Underground water. But it's use is possible only for small size of diameter less than 300mm, because large size plastic pipes are not readily availabe. For large diameter infiltration gallery, porous concrete pipes are now used, but it's heavy weight brings difficulties in making, moving and setting of the pipes. With it's conventional method of filter setting, fine sands are brought into the pipes to make trouble to lifting pumps and channels Therefore, initial construction cost and maintenance cost become high. To solve-this problem, new method is developed and tested. Small PVC pipes(diameter 14mm) are assembled at the site of construction to newly devised I beam type circls. The size of circular inpiltration gallery is optionally determined by I beam type circle which support small PVC pipes and is made of PVC amterial. This gallery are wrappd with syntheitc filter to prevent sand instruction. In this test, the diameter of 300, 400, 500mm were used. I beam type circles were made with PVC plated with thickness. t=6, 9, 12mm. Water quantity collected through the PVC circulor gallery are measured and the strengths of the gallery. 1. Allowable setting depth of gallery pipe below graund for the case of t=6mm, D=500mm is 2.72m. 2. Collected water quantity depends on soil texture, depth of water grandient of water surface, filter material angle of setting etc. 3. About 126% of water quantity collected from the one gallery pipe measured in two gallery pipes of two parallel installation.

The purpose of this study is to investigate and analyze the compositional elements of plan of art museums by selecting architectural works, which have strong symbolic meaning when evaluating value, from architectural works by Louis Kahn. First, the centrality of artworks, which are being displayed at the Yale Art Gallery, is complex. It includes three patterns of Void (spatial) Centrality+Symbolic Centrality+Functional Centrality among the five patterns suggested in this study. Second, the ratio system of interior space, which is expressed in the extension of the Yale Art Gallery, can be classified into the floor and walls. The floor used the square 1:1 ratio system. The ceiling used the grid patterns of equilateral triangles (regular tetrahedrons). It was applying a geometric ratio system when creating forms by using one side as a beam and the other sides as decorations of the ceiling. Third, the contours of interior space, which were expressed in Kahn's works, used the method of forming separate space according to the contouring rule (structural unit) defined by columns, and they were used in constructing the entire space through the integration of separate spaces. Fourth, according to the characteristics that were expressed by artworks displayed within the Yale Art Gallery Extension, the concept of accessibility was not as clear as that of residential buildings, because an approach of respecting existing architecture and context was used, rather than the starting point of interior space, or differentiated circulation, which has the function of a determined position.

A gallery provides the function to make opportunities for artist to meet the customers who would buy the products from them. And there was performed the place where artist who production provider, planner, managers and private collectors met to distribute artworks and to educate fine art for public and provide a chance sending leisure time. We investigated this galleries at old urban center in daegeon region by the deep interview and Delphi method. A galleries was operated by a sense of duty and pride. Though its environment is poor, it grows up the young artist and art trends. By delphi results, the role of gallery is recognized as the discovery of an unknown young artist and provider of art trend and paradigm. Also they was recognized as the space for social and cultural responsibility operation culture. Galleries was recognized as key factors as literary value, marketability and harmony between gallery and artworks. Artist was known as a key factors as gallery's expertise, gallery awareness and capacity for artworks selling. Gallery will be considered the functions as the various cultural experience space and culture service space. Although galleries are passive and one dimensional functions.

Most of water curtain cultivation (WCC) area in Korea has been inveterately suffering from the gradual draw-down of groundwater level and related shortage of water resources at the late stage of WCC peak time. To solve this problem, artificial recharge techniques has been recently applied to some WCC area. This study introduces infiltration gallery, which is one of the artificial recharge methods, and tentatively examined the effectiveness of three galleries installed at Sangdae-ri WCC area of Cheongju City. Seven galleries are set up at each empty space between eight vinyl houses in this area and its dimension is designed as 50 cm in each width and height and 300 cm in each length. Installation process was including bed excavation, backfill with gravels and silica sands, and completion of gallery by equipment of piezometer and covering with non-woven cloth. For each B, C, D gallery, 3 types of test including preliminary, four step and one long-term injection were performed. The first preliminary test showed the rough relations between injection rates and water level rise as follows; 20 cm and 30 cm level rise for $33.29{\sim}33.84m^3/d$ and $45.60{\sim}46.99m^3/d$ in B gallery; 0 cm, 16 cm and 33 cm level rise for $21.1m^3/d$, $33.98m^3/d$ and $41.69m^3/d$ in C gallery; 29 cm and 42 cm level rise for $48.10m^3/d$ and $52.23m^3/d$ in D gallery. Afterwards, more quantitative results estimating effectiveness of artificial recharge were reasoned out through stepped and long-term injection tests, which is expected to be employed for estimating water quantity re-injected into the aquifer through these galleries by natural injection over the period of WCC peak time.

The connecting rod big-end bearing is one of the most heavily loaded components of the lubrication system of high-speed combustion engines. The supply oil flow has to pass to the main bearing and the rotating crankshaft before entering the connecting rod bearing. It is common knowledge that the centrifugal forces due to the crankshaft rotation influence the oil flow to connecting rod bearing through the oil supply bore, especially, when the oil supply system to the connecting rod bearing has a 180$^{\circ}$circumferential groove via a single drilling in the crankshaft. In this case, it should be confirmed that the groove oil pressure in the main bearing is sufficient to overcome these centrifugal forces. For the purpose, the dynamic oil pressure before entering oil supply bore to the connecting rod bearing was measured instead of averaged oil pressure in main gallery. Experimental test results show that the dynamic oil pressure in the oil groove was more useful than that of main gallery. And it was also found that the oil pressure fluctuation in the groove was sensitively affected by the reduction of the main bearing clearance.

This study examines Safdie's design philosophy: place, purpose, and process and design strategies found in museum buildings. Safdie, influenced by personal background as immigrant, education of McGil University in Canada, apprenticeship from Louis Kahn, is one of the most recognized architects who designed renowned public and cultural buildings after Habitat 67 in Montreal, Canada. In order to reveal design strategies his eight museum buildings has been selected and analyzed in terms of interpretation of context, program presented in floor plan and section design, and the process of integrity found in structure and material. The results of this paper can be summarized as follows: 1) Reflection of existing context and regeneration of the locality has been in a creative way to reinforce the sense of place. 2) The layout of major and gallery space is determined according to the Safdie's interpretation of the site context and this can be categorized into three types. 3) Integration of the innovative structural frame and material has been experimented by using tartan grid and toroid form in the major and gallery spaces. This study is intended to reevaluate the significance of Safdie's design approach to building uniqueness of the site, program and tectonic.

The Wallace Collection in London (one of the national museums in the UK) has a gallery dedicated to conservation related displays. As well as permanent displays on the manufacturing techniques and materials of artifacts, there is a specially designed space for temporary conservation exhibitions. Through the example of the current conservation exhibition at the Wallace Collection and similar exhibitions and displays from other museums in the UK, this paper will study how the relationship and communication between the conservation profession and the general public have changed, from conservation as a behind-the-scenes and little-known activity to a closer interaction with the public and as a direct educational tool. The general function of a museum can be seen to have evolved from providing passive information to its visitors to offering more active and various forms of education. Conservation has developed with this change towards more awareness of the profession and its role in the preservation of cultural heritage through public outreach programs and displays.

The purpose of this study is to derive interaction types that appear variously in immersive contents through John Dewey's empirical theory, and to explore how the derived types are delivered in real cases. For this reason, two cases of the National Museum of Korea 'Immersive Digital Gallery' and 'Arte Museum Jeju' were analyzed through interaction types derived from the empirical theory. The interaction types derived based on the experience theory are the elements of 'multi-sensory', 'simultaneous experience' and 'sensory expansion'. In both cases, these types appear connected rather than grafted one by one in common. In one direction, 'multi-sensory' leads to 'sensory expansion', and in two directions, 'simultaneous experience' leads to 'sensory expansion'. As such, the core types of communication between technology and humans are not delivered one by one, but a cycle of interaction is formed in multiple ways. Therefore, it can be seen that the interaction type of immersive contents is expanded step by step by fusion of various senses and experiences in various fields, rather than a 1:1 partial delivery method. Based on this, it will be necessary to study how types are expanded and how viewers are affected when interaction is implemented in immersive contents in the future.

The purpose of this study is to understand the classroom facilities of England and USA in the 19th century. This kind of study can provide the meaning of past, present, and future on classroom facilities. The results of the study are as follows. First, England classroom in the 19th century was made up of a large space, a gallery, that could teach a large number of students at the same time. Second, the classroom facilities of USA in the 19th century were developed by reformers for the purpose of training the labor force of educational thought and industrial development. Third, some characteristics of classroom facilities of England and USA in the 19th century were also found in school facilities of Korea at the same time. Fourth, large gallery classes began to disappear in the mid-19th century and were transformed into small 'class' facilities to improve efficiency. Fifth, the word 'class' did not appear as a substitute for the school, but as a meaning of subdividing within the school. Sixth, these classrooms consisted of smaller classes, and they began to create and teach common and unified curriculums to harmonize the differences between classes and to manage all students efficiently and effectively. Seventh, the basis of the classroom of England and USA in the 19th century was the design of one teacher to efficiently teach a large number of students, and there was a difference in size, but the current classroom facilities have been maintained to some extent. Eighth, since the end of the 19th century, the compulsory education system has been discussed and gradually introduced, requiring more schools and classroom facilities, and labor and capital have been emphasized by the development of industrialization. Ninth, follow-up studies are needed to analyze how classroom facilities have been universally transformed since then, based on class facilities in the 19th century, and what educational, social and political contexts have been added in the process.
