The purpose of this study is to find out the changes on the metropolitan condominium apartment unit plans based on the interior spaces related to women such An-bang (master bedroom), bathroom and attached spaces to the master bedroom, living room, diningroom, kitchen, utility room, and balcony. This study used the content analysis method and space syntax. Contents were limited to the floor plans with 3 rooms type and about 105 m2 in the Korean apartment encyclopedia. The unit plans of 2,278, built from October 1975 to January 2008, were analyzed and basically SPSS package 16.0 was employed. The results were as followed. 1) Living room was a core space and an increasing tendency. After 2001, the design trend of living room connected with kitchen and dining room, and dining room changed into one space combining with women's working space such kitchen. It meaned women's working activities became into family public activities as to depending open access. 2) Kitchen had a characteristics that was connected to utility room or back balcony, and the number of extra kitchen increased. Also, the size of DK decreased, but utility size little increased. It was showed the characteristic of this space was still for women. 3) An-bang had a little strong characteristics of married coulpe or women's personal space with bathroom or dress room/powder room. 4) In addition, the values of integration and control of living room and DK were highest. It meant these space were centered in unit plans. Next, the An-bang and dress room/powder room were high. Utility room or balcony's were next, and these were women's working space. Therefore, family's public space was most important, and married couple or women's personal and working space were later in planning.

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.

This study has been conducted so as to analyse user's sensibility on lighting method, correlated color temperature and illumination by composing surface light source, which was projected onto a unit side of interior wall, ceiling and floor. 1) As an analyzed results of the sensibility images, it showed that the "snug & tender" value had got higher when the correlated color temperature got lower. And the "energetic, cheerful" value had got higher when the level of illuminance got lower. Furthermore, the "unusual, unique" showed higher value on the illuminated floor circumstance. Finally, the higher correlated color temperature had been, "energetic, cheerful" value also got higher. 2) As a result of multi-regression analysis, it was found that 3000K and 100lx had the biggest influence on 'snug' image while 5,500K, 500lx had the biggest influence on 'energetic' image. In addition, it was found that the illuminated floor had a big influence on 'unusual' image while 500lx had the biggest influence on 'refined' image.

The purpose of this study was to identify the universal design characteristics in residential environments. The subjects were 135 physically disabled persons who lived in the rental multi-family housing apartments in Pusan. Interview method was used for this study. They were an average age of 51 years and 63% were male. They were low income families and lived in 12 pyung ($39.75\textrm{m}^2$) apartments. They were asked about what housing characteristics were constraints in their daily living. They pointed out that the constraints in their apartments were as follows: 1) the small amount of space in the bathroom, kitchen, bedroom, and the entrance area of housing unit, 2) the unflat floor level between the bathroom and the hallway, or the balcony and the bedroom, 3) the slippery floor finish in the bathroom, 4) lack of grab bars or handrails in the bathroom and the ramp, 5) the kitchen work centers and the electric switches at improper height, and 6) the steep ramp. Therefore, the universal design characteristics in residential environments were the adequate amount of space, flat floor level, non-slippery floor finish, grab bars or handrails, accessible height, and ramp.

This study was conducted to evaluate the effect of different housing systems on the performances of sows and their piglets during gestation. A total of 90 sows (Landrace ${\times}$ Yorkshire) were employed into 3 experimental farms to give 3 treatments, stall housing, group housing in either slatted floor or litter floor. Individual sow was used as an experimental unit. Group housed sows were fed with electronic sow feeder during gestation. Performance measures were taken on sows and piglets. Back-fat thickness and body condition score of sows were not affected by housing systems for pregnant sows. There was no difference of estrus interval of pregnant sows between housing systems. The lower number of still-birth was observed in group housing type. The number of wounded sows in slatted floor was remarkably increased compared with sows in litter floor. This study showed that the housing systems could fairly impact sow and piglet performances.

The purpose of this study is to evaluate environment-friendly planning feature in Environment-friendly Certificated apartments and to use the basic planning data of housing. Seven Environment-friendly Certificated apartments have been analyzed. The findings of this study are as follows: Environment-friendly planning features are categorized into 4 items; floor planning feature, material planning feature, universal planning feature and environmental planning feature. Among floor planning features, natural sunlight, built-in closets, and differentiated floor plans are well considered, but the flexible floor plan for resident's lifestyle and green space are lack. Among material planning features, environment-friendly finishing materials, environment-friendly products and energy-efficient double-pane windows are well considered, but implementation for resource savings using recycled materials are lack. Among universal design planning features, removal of threshold and installation of safety device in bathroom are not well considered. Among environmental planning features, usage of alternative energy like solar energy are not applied. The environment-friendly planning features in interior space should be introduced in diverse ways.

Today, apartment is the primary housing type in Korea. In the past, there were many apartment floor plans in the same design way. There have been changes to complex and luxury plans in these days because people want to fit their own needs and wants to the plans. The primary purpose of this study is to analyze interior design trend of medium-large size apartment after year 2000. For that, this study used 7 different construction companies, 13 apartment complexes and 30 unit plan cases which were on sale from April 2007 to April 2008 in Seoul and the Metropolitan area. The results of analysis are as follows: First, most cases had 4LDK and 2bathroom with a dress-room. Second, characteristics of the interior design showed that the variety finish materials used in the units. For wall finish materials, wallpapers were used in mostly regardless in different areas. For floor finish materials, stone and tile were used in similar ratio in the entrance area whereas wood floor mostly was used in living room and kitchen areas. This study shows some significant characteristics of today's apartment even it has some limitations because of small amount of survey cases. More detailed and deeper study will be done continuously.

Started in 1989 as Public Permanent Rental Housing scheme, public rental housing lease policy is increasing target residents and supply in each government by introducing new supply types. However, public housing business entities have difficulties in expanding the supply due to cumulated deficit. The research suggested long-term public rental housing reconstruction business as a method to preserve the cumulated deficit from the previous. Minimum floor area ratio mathematical model was suggested by defining the floor area ratio of reconstruction business as minimum, since housing sales profit after reconstruction could preserve aggregated deficit, and mathematically approached by considering the traits of long-term public rental housing reconstruction. The determinant for minimum floor area ratio mathematical model comprise cumulated deficit of the existing long-term public rental housing, land size of reconstructed sale housing, housing sales price per unit area, and business cost per unit area. Minimum floor area ratio mathematical model is expected to be the milestone for supporting decision making regarding the economic part of old long-term public lease housings' reconstruction scale, and expanding housing supply within urban area.
