The purpose of the study was to analyze the appropriateness of space in multi-family housing by examining the current conditions of space, space norms and deficits, satisfaction with and needs for the spaces of individual rooms. The data came from the survey with 412 households living in Haeundae New Town, Busan and were analyzed with descriptive statistics. The appropriateness of space were mainly investigated in terms of housing size, number of bedrooms, and number of bathrooms. In terms of current space conditions, the highest portion of the households live in apartments with $20\sim30s$ pyong, 3 bedrooms, and 2 bathrooms. It was found that the space norms included housing with $30\sim40s$ pyong, 3 bedrooms, and 2 bathrooms. Households in current study tended to have some space deficits, especially in housing size and number or bathrooms. In general, the satisfaction with the current space of individual rooms were generally low except living room and master bedroom. It was also found that the households were more likely to make the second biggest bedroom bigger than now. The stages of family life cycle has significant effects on needs for the spaces of several rooms, such as dining room, room2, and room3.

Apartment, which have become the major housing style in Korea, have contributed to the development of housing culture as well as achieved a growth in volume. However, the demands and characteristics of residents have not been reflected in the apartment. because it has been developed only for a growth in volume. In this society, apartments need to be developed for resident. Therefore, the purpose of this study is analyzing apartment design factors and examining the appropriateness of apartment residents. To do so, questionnaire research is conducted and 90 questionnaires are analyzed for this study. The questionnaire mainly consists of questions about residential appropriateness of each space, and reaction and coping behavior on the inappropriate residential environment.

The appropriate area for human's most basic living space is an important factor. Therefore, the 'minimum housing standard' is a very important factor to ensure a minimum quality of living space for human life. In Korea, however, the importance of the 'minimum housing standard' has been neglected for about 20 years. Even in Korea, the 'minimum housing standard' has become an nominal existence. In other countries, studies have long been conducted on the minimum housing standards, but studies have shown that studies on the minimum housing standard are not actively occurring in Korea. The purpose of this study is to diagnose the current status of the 'minimum housing standard' in Korea and to explore the direction of future research. The study included a total of 29 researches commissioned by the Korea Academic Research Institute (KCI). To ensure the objectivity and reliability of the analysis, analyzed year of research, field of research, method of research, contents of research. Through this study, it is possible to grasp the tendency of previous studies on 'minimum housing standard' in Korea and it is meaningful to increase the usability of 'minimum housing standard' in residential planning. It is also expected that future research on 'minimum housing standards' will be able to present the direction of the field to be developed.

Single formative language created by the standardization of industrial society carries a cell constructive aspect. Such space structural form made gigantic buildings, which has a symbolism as an independent object. Such space shows a morphological symbolism by public preference but it did not establish essential meaning of a shape or concentrated relation. In this regard, this paper tries to show organic similarity of structural formality of small commercial space (patterned space), which was made by the continuity of concentrated patterns not an object of dualistic unit features. Therefore, this study analyzed the cultural, commercial and public space based upon systematical concept and features. Systematical space formality that makes multilateral relation between human, environment and a thing is a concentrated view point by relational features not by the cluster displayed by hierarchical features. Systematical space of small patterned space emphasized its appropriateness of expansion and creating diversified spaces unlike gigantic symbolic buildings.

Every assumptions on the importance of urban green space were highly valued by urban and land-scape professionals. This paper, therefore, investigated residents' values on urban green space as a first stage study on the role of green space in metropolitan region. Case study area was Taegu city. Questionnaire was main tool for the investigation. This study discussed operationtional defition of green space and the appropriateness of the hierarchy of green space in order to examine the changing role of urban green space in terms of people's values on green space. The investigation proposed that the people's values were quite different from those of the professionals' and suggested the need of new method which was more suitable to investigate people's emotions and values on the green space in the city.

This paper is on speed control of induction motor using space vector PWM. Indirect vector control which controls independantly flux and torque current component in order to drive induction motor, is applied for driving motor. Voltage sourced inverter with space vector PWM is used to generate the practically perfect sinusoidal flux density in induction motor. The appropriateness of speed control is proven by appling IP(Integral-proportional) controller which is known to have a good speed response and still to have less overshoot than the now used PI(Proportional-Integral) controller.
