All the text of housing in 1910s was conveyed in three; hygiene general readings, home economics texts saying women's responsibility of cleaning house, and Japanese's observation and criticizing Korean housing. It stressed sanitary conditions of housing and criticised Korean housing dirty, of which contents and logic were same with the housing discourse in 1900s but much simpler and smaller in amount. It was mainly written by those in medical treatment field like doctors for enlightenment of private hygiene practice to Koreans. Because Choson Government-General(朝鮮總督府) excluded Korean residental areas from urban sanitation project, they remained dirty in 1910s. The practice of housing sanitation remained just as a matter of private sanitary practice. These political and discoursive conditions insinuated a sense that Korean dirty housing was representation of Korean's uncivilized customs and manners and a reason for being colonized. This sense made many Koreans to insist their housings' reforming to sanitary states just for civilization during colonized period.

The greenhouse type metal structures are increasingly used in modern construction of livestock farms because they are less laborious to construct and they provide a more favorable microclimate for the growth of animals compared to conventional livestock structures. A key stress factor for metal structures is the wind. The external pressure coefficient ($c_{pe}$) is used for the calculation of the wind effect on the structures. A high pressure coefficient value leads to an increase of the construction weight and subsequently to an increase in the construction cost. The EC1 in conjunction with EN 13031-1:2001, which is specialized for greenhouses, gives values for this coefficient. This value must satisfy two requirements: the safety of the structure and a reduced construction cost. In this paper, the Navier - Stokes and continuity equations are solved numerically with the finite element method (Galerkin Method) in order to simulate the two dimensional, incompressible, viscous air flow over the vaulted roofs of single span and twin-span with eaves livestock greenhouses' structures, with a height of 4.5 meters and with length of span of 9.6 and 14 m. The simulation was carried out in a wind tunnel. The numerical results of pressure coefficients, as well as, the distribution of them are presented and compared with data from Eurocodes for wind actions (EC1, EN 13031-1:2001). The results of the numerical experiment were close to the values given by the Eurocodes mainly on the leeward area of the roof while on the windward area a further segmentation is suggested.

A common control model used to implement computer integrated manufacturing(CIM) is based on the hierarchical decomposition of the shop floor activities, in which supervisory controllers are responsible for all the interactions among subordinates. Although the hierarchical control philosophy provides for easy understanding of complex systems, an emerging manufacturing paradigm, agile manufacturing, requires a new control structure necessary to accommodate the rapid development of a shop floor controller. This is what is called CSCW(computer supported cooperative work)-based control or component-based heterarchical control. As computing resources and communication network on the shop floor become increasingly intelligent and powerful, the new control architecture is about to come true in a modern CIM system. In this paper, CSCW-based control is adopted and investigated, in which a controller for a unit of device performs 3 main functions - planning, scheduling and execution. In this paper, attention is paid to a planning function and all the detailed planning activities for CSCW-based shop floor control are identified. Interactions with other functions are also addressed. Generally speaking, planning determines tasks to be scheduled in the future. In other words, planning analyzes process plans and transforms process plans into detailed plans adequate for shop floor control. Planning is also responsible for updating the process plan and identifying/resolving replanning activities whether they come from scheduling or execution.

The modern town houses in Philippines has been changed through Spanish colonization over 300years and American military administration in 20C. Especially Cebu, the first contemporary capital of colonized Philippines by Spain, has various cultural characteristics and historical remains including old houses. By the economy condition in Cebu growing up, Bahay na bato, stone and wood house, has been settled for the elite or middle class of Cebu around 19C influenced by Spanish or Europe and Philippines native house called bahay kubo. Bahay na bato shows a common features, as revealed in this study, which all of them has a two stories with cut stone curtain wall and wooden beam and lintel, fronting the main street by approaching directly from street. And spatial separating also shown by setting living space to upper level instead of using storage or entrance hall called zaguan in lower level. Bahay na bato studied here shows a particular appearances in elevation, having volada and elaborate geometric or floral window pattern, also playing a role for ventilation with vetanilas below volada and main window in section. They have a rectangular plan with caida, sala, comedo, azotea almost similar to Spanish and ealier colonial Mexico style mixed with Philippines traditional style showing the strong spatial separation functionally and space wideness for party occasionally.

This is a study on the ㄱ-shaped church in Korean Protestant churches. Since the Protestantism had been introduced into Korea, the style of ㄱ-shaped church was the popular style that have been fashioned in all the country of Korea. When the Protestantism was introduced into Korea, ideology which ruled over the Society of Chosun Dynasty was the Confucianism that emphasized the precepts, for example, the loyalty for the King, distinction between the sexes and so on. The Korean Protestants built the church which had ㄱ-shaped plan, so that they solved the second problem : 'distinction between the sexes'. The style of the ㄱ-shaped church is one of the characteristics which distinguish the Korean church from other nations'. Actually the ㄱ-shaped churches had been built by Korean Protestant denominations, from the early days of introducing the Protestantism till the end of 1920's. Even though most of the style of the ㄱ-shaped church is replaced with the modern style according to the extension of religious influence, luckily the ㄱ-shaped two churches : Kumsan Church(1908), Toodong Church(1929) are in existence in the Provice of ChonBuk. The purpose of this study is to make the architectural characteristics of the ㄱ-shaped church clear. This study is based on the actual survey of the ㄱ-shaped churches in existence: Kumsan Church, the Toodong Church and on the documents, photographs, interviews and so on for investigation not existing one now. The ㄱ-shaped church have the plan to separate men's side from women's with a right angle and have a pulpit which was placed at the meeting point of the front part of men's and women's sides. Generally, seen from the court, the churches have men's side in left and women's one in right. There was a screen blocking both sides in the church. But it disappeared in 1920's according to the change of the social conventionality. Most of its structural form is the Korean wooden style. The ㄱ-shaped church appeared in a transition period of the Korean church architecture.

The formation of Chinese Town in Malacca of Malaysia and Singapore would explain that Chinese gradually played an important role of commerce and urban service according to the Western European advance to southeast Asia and the construction of colonial cities from the 16th century to 19th and massed residence in many cites of southeast Asia. Chinese was usually separated from the Western European by western colonial policy and city planning. Common architectural characteristics in Chinese towns of Malaysia can refer to the transmission of the Chinese architectural material, the combination of dwelling and commerce in a house and the space organization centered on a court or an air well in the narrow and long site, lying adjacent to street etc. The Chinese dwellings in Malaysia rooted with Chinese settlement in southeast Asia. The Chinese dwellings was not always a shop on 1th floor and a dwelling on 2nd floor before the 19th century. But as Chinese immigration and commercial activity progressed in earnest in the early of 19th century, the row house of Chinese for dwelling was autonomously changed to two functional shophouse for dwelling and commerce. Chinese row house can refer to the use of Malay regional material, change of symmetrical Chinese traditional housing type by the narrow and long site and the tendency of the eclectic elevation of Western and China. Another architectural characteristics of the shophouse is an appearance of the continuous verandah with a cover regulated by Stamford Raffles in Singapore. This regulation was applied to architecture in Chinese Town as Stamford Raffles constructed Singapore. It was spread to South China reversely and became the regulation of streetscape for the modern city. Shophouse of Chinese towns in Southeast Asia and south China can be understood by context of Chinese immigration, colonialism, housing type of commerce and dwelling and the Western European city planning.

The color and structure of urban constructions is a factor of urban landscape and shows their characteristics. Hence the modern buildings deal with their materials and external appearance as an important factor, making up the urban image. But it was nearby impossible to evaluate the value of visual landscape with objective measuring method. Most of all, it depends on the subjective estimation of a few talented or high educated experts with a sense of beauty. Such kinds of estimation can in some cases include arbitrary interpretations. In relation to this kind of problems, it is tried here in this study to analyse the human response of brain wave pattern (EEG) with use of SD method, while the tested persons watch the urban landscape scenery constructed in a visual reality. The tested persons were 20 adult male and female with no color blindness and intact cognitive function. Light source with color filter was used for color environment in a dark soundproof chamber. The signal of EEG is analysed digitally and grouped into the ${\alpha}$ and ${\beta}$ waves. The result showed that relative power of ${\alpha}$ wave ratio increased in the natural landscape scenery with blue and green color. From these results it was possible to evaluate the human response, which is affected by urban and natural color and structure stimulation and it might be useful as an indicator of visual cognition amenity toward the design of urban construction environment.

Although Graphite Compacted Vermicular (GCV) was first observed in 1948, the narrow range for stable foundry production precluded the high volume application of GCV to complex components such as cylinder blocks and heads until advanced process control technologies became available. This, in turn, had to await the advent of modern measurement electronics and computer processors. Following the development of foundry techniques and manufacturing solutions, primarily initiated in Europe during the 1990s, the first series production of GCV cylinder blocks began during 1999. Today, more than 40,000 GCV cylinder blocks are produced each month for OEMs, including Audi, DAF, Ford, Hundai, MAN, Mercedes, PSA, Volkswagen, and Volvo. Given that new engine programs are typically intended to support three to four vehicle generations, the chosen engine materials must satisfy current design criteria and also provide the potential for future performance upgrades without changing the overall block architecture. With at least a 75% increase in the ultimate tensile strength, a 40% increase in the elastic modulus, and approximately double the fatigue strength of either iron or aluminum, GCV is ideally suited to meet current and future of engine design and performance requirements.

As an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society, the numbers of the elderly who suffer Empty Nest Syndrome and LID (Loss Isolation Depression) syndrome have been accelerated. These syndromes involve psychological instability, melancholy, and lethargy. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing house into shared housing was set as a hypothetical solution in this study. This study sets out to find out responses of the elderly to alter their own house's function in housing improvement area. A Small Workshop Panel method was used and the elderly aged 55 years upwards took part and they own a detached house in a housing improvement area that is relatively large for the elderly or the elderly couple to live alone. Through the workshop, problems that the elderly have been experiencing within their houses were looked into and responses of the elderly on altering their house to shared housing by introducing developed schematic plans. Although, the first response was negative, positive responses from the house owners were carried out when a visual support i.e. developed shared housing plan was provided. The positive response was based on the fact that subsidies from the government on house renovation and tenants matching programs are supported as shared housing could provide home owners economical support with rents and help them to feel less lonely. This is a way of relieving the elderly from being neglected and supporting them to live and age actively in their later lives. Furthermore, by providing a visual media to the elder residents in housing improvement area, their greater understandings on the development and addressing their opinions were possible. Therefore, more tools that promote elder residents' participation are needed for future housing improvement projects and an aging society.

The year 2003 is the centennial of the birth of the modern lighthouse in Korea. The lighthouse was originally surrounded by a beautiful nature and it contains the romantic sensitivity which relates with the ocean. And in some case it is a environment-friendly architectural facility which uses a alternative energy like a solar cell. Now the properly developed manned lighthouse is not only functioning as a traditional aids to navigation for the vessel, but also it becomes the new facility and space for all civilians who might visit and experience. Jeju regional maritime affairs & fisheries office has developed the manned lighthouses properly to ocean cultural space for the past several years. As a result of that, the recognition regarded on ocean culture was raised and the regional tourism was vitalized. For this situation we intended to reveal in this study that all the issues which relate to the proper use of the manned lighthouse in the Jejudo, since the project of water-familiar space started by MOMAF.
