Resilient materials are generally used for the floating floors to reduce the floor impact sound. Dynamic stiffness of resilient material, which has the most to do with the floor impact sound reduction. The resilient materials available in Korea include EPS (Styrofoam), recycled urethane types, EVA (Ethylene Vinylacetate) foam rubber, foam PE (Polyethylene), glass fiber & rock wool, recycled tire, foam polypropylene, compressed polyester, and other synthetic materials. In this study, we tested floor impact sound reduction characteristic to a lot of kinds of resilient material. The result of test showed that the amount of the heavy-weight impact sound reduction appeared by being influenced from this dynamic stiffness of resilient material. The dynamic stiffness looked like between other resilient materials, a similar to the amount of the heavy-weight impact sound reduction was shown.

This paper proposes a new operation algorithm for elevator by considering both better service for passengers and minimization of energy consumption for elevator operation. The main idea of the proposed operation algorithm is based on the assumption that passengers push the numbered buttons indicating their destination, one of the main differences of proposed operation mode from the conventional one is that the elevator may move to the opposite direction for a few floors according to the rescheduled operational pattern determined by some factors. Some examples by computer simulation show the efficiency of the proposed operation algorithm.

Under the rule of Japanese Imperialism, there were two kinds of architectural government organizations inside the Chosun(朝鮮) Governor-General which designed To(道) and Pu(府) government office buildings; one was the organization inside the central government office and the other inside the local government offices(To and Pu). By the administrative approval procedure of the Chosun Governor-General, the local architectural organization planned site and floors of the building in the schematic design stage, and in the detail design stage not only the central but sometimes the local planned the building design. The design accomplished by the local in schematic stage was believed as a kind of guideline in detail design and the local organization was able to insist their own needs to the central and to change the central's planning. Even though the central had the authority of the design, the local took part in the planning of To and Pu government office buildings at least in the schematic design stage.

The construction industry is typical of the ' job of 3D ', the automated construction equipments are getting used in the domestic construction sites and the construction robots began to be sold in the abroad. The research developed the small sized robot which could be used at the apartments and the office buildings with the small floors. But the past finishing robot could not be operated easily, it had expensive controller which could not increase the production of robot. In this paper, user interface is made to operate easily the small concrete floor finishing robot with two trowel which has low cost controller, motion algorithm including modeling and mechanism about the concrete finishing robot is developed to control moving. Simulation and experiment figure out how the finishing robot moves and will contribute to realizing it.lizing it.

This studies is the typological study to classify the characteristics of Floor plan in wooden house that is built in the suburb of Korea through case studies. For this type classification, I took several criteria as follows: number of floors, location of entrance, approach way to inner room, location of step, arrangement way of public space and private space, those are considered as important elements for the determination of Floor plan. Ive got 10 representative types by analysing and synthesizing the relationship between these elements. I expect that these study results would be good materials for the developing new model of wooden houses that is more proper to our life.

According to office building design in Korea, building exterior and office automatic systems through introducing IB system have been improved. However, the lower floors of a building are functionally easy to transfer but actually functions as an enterance. Although at takes a large investment by the owner or enterprise, mainly the tenants and neighbors are in a broad sense the actual users. In this point of view, the lobby of an office bulidling which is the connection between the exterior as a public space and the interior as a private area, does not only have the function of an enterance but also has to be an image of the enterprise or the building itself. Therefor the lobby must contain various functions of space.

The purpose of this study is providing useful information for consumer-friendly house plan by investigating remodeling apartments according to the area type and size. In order to achieve this aim, case study was applied. The case study was conducted of five small, medium, and large size apartments through depth-interviews, actual survey, and questionnaires on the remodeling behavior, interior design, and interior atmosphere. The results of the study are as follows: Structural alterations were frequent in communal area, and then in private and household areas. Changing lighting fixtures was frequent in all area types, and especially, in communal areas installing extra decoration was frequently observed. Besides, alterations of doors and window frames were carried out in communal, private, housework and service areas by using wood, aluminum sashes, double-glazing, and paint coating. Finally, in housework areas the material and color of counters were changed into wooden and achromatic.

The purpose of this study is to provide a basic information for the plan of neighborhood facilities as residential environment. For the purpose of this study, this paper is to investigate all criteria of neighborhood unit on the related laws and regulations, As a result, the legal criteria of neighborhood unit has come to no conclusion of terms(the neighborhood life facilities, the life benifit facilities, the neighborhood facilities, etc.) and ranges(the density of population, the number of floors, etc). Therefore a consistent neighborhood unit can be applied to the development plans of new cities as well as new residential areas for the future.

This study proposes a method of generating steel house shop drawing in an automated design method, reducing construction manpower and period. With one hour fire-resistant approval code, reflecting work ability and efficiency, steel-framed house market is expected to extend from one or two story house to multi-purpose facilities up to four story height. More models have been constructed in this system than the first appearance of fire-resistant approval in Korea in 1997 Also, cost estimation of components such as frame walls, roof trusses and floors is obtained with shop drawings. Also, the lack of suppliers of steel framed house shop drawing and unstandardized drawing method get constructors have difficulty in understanding its design. In steel framed house industry, shop drawings are essential part in building and constructing framework and they have major effects on construction deadlines and expenses. By exploring method of shop drawing automation, this study aims to optimize work flow with a standardized drawing method. The proposed system can be applied to manufacturing automation in domestic industry of factory-built panelizing method in the near future.

The purpose of this study is to Investigate color schemes, degree of its satisfaction, and color implication of office environment. This study is to find the proper current color schemes in offices today, as well as colors that will enhance efficiency and productivity in work for future uses. The study was progressed through visiting offices and survey The collected data were analyzed by using such descriptive statistics as percentage, frequency, mean, and t-test. The result of this study shows that most of offices applied the main color only for ceilings, walls, and floors; and, some of them applied supporting colors in addition to main colors. In general, workers are not satisfied by the color in their work environment. Therefore, careful planning and exploring color schemes of main colors and supporting colors in work environments can be suggested. Also, the study results of color implication in work environment indicates that there is a need to take a careful color planning, especially in relation to the type of work, sex, and the level of education of a worker.
