Nowadays great changes arises from the digital environment and technology. And Also, our living environment are changes very rapidly. The purpose of this study was to analyze the characteristics and trends of future housing reference to ubiquitous housing cases in U.S.A, Japan and Korea. From these cases, reorganized ubiquitous-apartment elements are suitable to our housing environment. To search them, it is investigated to 4 ubiquitous housing examples, such as Aware Home, Toyota's PAPI, samsung raemian's housing gallery and GS E&C's apartment. In this study, we could get types and characteristics and planning elements of ubiquitous housings. The findings showed that many kinds of common network systems were suggested and were acted in limited spaces. In conclusion, it was considered as the one of the most suitable future housing type that had a special feature of the demands of residence and life with free accessibility of information and data. Especially, it is necessary to prepare for coming aging society.

The purpose of this study was to examine the effect of housing units assembled as complexes on residential satisfaction. Two analyses were performed to examine residential satisfaction of Multi-Family Housing Blocks (MFHB; complex) and Multi-Household Housing (MH; non-complex). The residents from both housing types were surveyed on nine categories of questions regarding residential satisfaction and one on overall satisfaction from their experiences. First, the t-test results between MFHB and MH suggest that MFHB has insufficient effect in terms of improvement over MH, as their satisfaction differences are either insignificant or uncontrollable. Second, the common factors affecting Overall Satisfaction of MFHB and MH are Maintenance and Residential Environments.

The influx of the apartment housing culture have passed thirty years, but it has been pricipally developed that in terms of the urban's residents. There is very important problem when we think about the improvement of housing's life of dwellers in rural. Therefore, as increased demand of apartment housing and dweller's needs in rural we think that there is worth studing to the residents of rural's apartment housings. The purpose of this study is to understand the housing in rural, to discriminate between rural's and urban's apartment housing plan and to adapt to basic data to satisfy request of rural apartment housing's residents according to the family composition.

Environmental conservation has become one of the greatest concerns of all the people in the world. This issue is related to wood utilization in two major view points such as carbon dioxide emitted by the use of manufacturing energy and absorbed during the growth of trees. Wood construction materials require less manufacturing energy, which, in turn, means less carbon dioxide emission. In addition, wood keeps absorbed carbon in itself as far as it is not burnt. Therefore, wood is environmentally superior to other materials in terms of potential effects on atmospheric carbon dioxide. As examples of the environmental effect of wood utilization, the following two results were obtained: 1) If wood construction becomes popular in Korea as in Japan, more than 24% of carbon dioxide emission during construction of residential housings can be reduced: and 2) If aluminum windows are substituted by wood windows, more than 19% of carbon dioxide emission can be reduced. If the principle of "cut and plant" is kept well, wood is the best construction material for environmental protection as well as human residence.

The bearing design includes the steps of selection bering type, selection bearing subtype, and determining the peripheral equipments. In this paper decision making methodologies are compared to propose a stepwise decision methodology to the bearing selection problem. An artificial neural network trained with design cases is used for selecting a bearing type in the first step. Then the subtype of the bearing is selected using the weighting method, high is a kind of multi-criteria decision making method. Finally, the types of peripheral equipments such as lubrication devices, seals and bearing housings are determined using a rule-based expert system.

Multi-family housings caused several problems related to physical form such as isolation of housing estate, inhumanity of the exterior space, and mismatch with the urban structure. To handle these problems, the purpose of this study is to analyse density elements which have a direct impact on physical forms, thereby understand the characteristics of physical form and also identify a meaning of inter-relationships between them. Therefore both formal constituents and density elements are reformed into respective analyzing indices. From the analysis, physical form and the spatial layout of buildings were more uniform in large-scale housing estates than in medium or small housing estates. However, small-scale housing estates showed various form and the spatial layout of buildings in order to increase the building density.

The development of idyllic housings, is in increasing growth in the suburban areas of Seoul, presents some critical problems such as in sufficient common open space and poor living condition, which are mainly caused by disorderly designed. Through comparing planning indices of idyllic housing, this paper aims to diagnose the condition and causes of those problems and to present some basic issues on improvement direction. The causes of problems can be summarized as the blind point in regulation system, the shortness of planning elements of a housing block which includes road systems and public facilities, and the mismatch of housing type with density, on which includes road systems and public facilities, and the mismatch of housing type with density, on which hereafter improvement suggestion should be focused. And this study suggest the simulation models on an ideal idyllic housing to be applied in our forthcoming idyllic housing of Korea, which can indeed become a generalized alternative to the livable idyllic housing.

The purpose of this study is to develop an underground Building. Population tends to concentrate in large cities. In result, the cities lacks housings. Underground space may be a attractive space by being able to gain alternative energy and get a cheap site, protect environment at the same time. The earth or ground is a useful medium for a long-term heat source and storage of it's heat. Also the underground space has the status of stabilization, the lower heating load and the similar heat transfer coefficient of the inside wall surface comparing to that of residential space. Utilization of underground space has many advantages to cope with lack of building sites and energy conservation, etc. As a result, it is expected to provide a useful information for the practical use of Underground building.

In this paper, research on the mold design of motor housing produced by the HPDC process was conducted using computer simulations and experiments. Recently, automobile parts have been required to be light and have high strength. The die casting process was used to manufacture automotive motor housings. In the die casting process, the control of casting defects is very important. However, it has usually depended on the experience of the foundry engineer. For the analysis of the manufacturing process of motor housing, the finite element method is applied. Through the simulations using commercial software, the filling pattern and product defects could be confirmed. The analysis results obtained from the filling behavior of the casting process agreed with the experimental results. The computer simulation results of filling behavior were reflected in the optimal mold design of motor housing.

In the hot strip mill, not only the chatter vibration of finishing stands has a great influence on the surface quality of hot products, but also that is the major factors to shorten the life of rolling mill housings or to create the machine troubles. As long as the mill has been operating, the low frequency chatter at the early mill stands (No.2 and No.3) of POSCO's Kwangyang No.2 hot strip mill had been detected when rolling certain types of products, e.g., thinner gage, hard grade products. For several years, the experimental study was undertaken to analyze the cause of the chatter vibration and establish the methods to avoid the vibration to acceptable levels. The analysis and solution to the vibration problem with recommendations and revised maintenance practice are the subjects of this article.
