The purpose of this study is to analyze the planning concept and spatial characteristics of the multi-housing units in prize-wining works of design competition since 2007. Literature review and content analysis were used for this study and 199units over $59m^2$ were analyzed to review the planning concept, spatial composition and layout. The results of this study were as follows; 1)The planning concept of these units were divided into three aspects; that is, eco-friendly, rational and sustainable unit plan by means of functional, environmental-friendly and future-oriented aspects. 2)Most unit plans had 3LDK+2bath and 4Bay types including family room as a public space. This results shows that family-room and bathroom has recently become more important than number of rooms in multi-housing units planning. 2)In terms of the spatial composition of LDK and Master Bed room, LDK area become large, open type and master-zone were showed 'bed room+dress and powder room+bath' type. 3)The entrance has a intermediated space as a balcony or a former space and the privacy of LDK space was protected from the entrance. This study has a significant moaning on grasping current trend in Korean multi-housing and to provide Information for future direction on housing-unit design.

The purpose of this study was to investigate the attitude of the middle and old age about the elderly housing and the planning elements according to the types of silver town. For this study, a pre-interview and a survey method were used for data collection. A questionnaire survey of 372 women over 45 years old was carried out. Among the data, 321 cases were analyzed by SPSS for Windows V12.0. The major findings were as follows: 1) Regarding the elderly housing, While the couple cohabitation type preferred the existing housing and the general housing, the single habitation type preferred the apartment and silver town. Some people wanted silver town occupancy due to the decrease of children support burden, the other did not want it due to economical burden and the absence of homelike affection. When they move into silver town, they wanted to take money, clothes, and photo album. 2) In silver town development, while the couple cohabitation type preferred the apartment, independent house, the single type preferred the apartment, housing complex and group-home. The unit housing sizes of them were around 82.6 and 49.6 square meters respectively. In the space composition of unit housing, while the couple cohabitation type preferred bath room, kitchen, living room and two of bed room, the single type preferred one of bed room and bath room at least. On the other hand, this study found out that it was possible to plan the space for eating and washing as the common space. 3) According to single or couple, and ages, there were significant differences in preferred spatial planning elements, which needs to be reflected in the silver town development. These results can provide improvement guidelines for the development of the silver town with the differentiation of design factors for the silver town planners.

In this work, nano-flake shaped nickel oxide (NiO) films were synthesized by chemical bath deposition technique for electrochemical capacitors. The deposition was carried out for 1 and 2 h at room temperature using nickel foam as the substrate and the current collector. The structure and morphology of prepared NiO film were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). And, electrochemical properties were characterized by cyclic voltammetry, galvanostatic charge-discharge, and AC impedence measurement. It was found that the NiO film was constructed by many interconnected NiO nano-flakes which arranged vertically to the substrate, forming a net-like structure with large pores. The open macropores may facilitate the electrolyte penetration and ion migration, resulted in the utilization of nickel oxide due to the increased surface area for electrochemical reactions. Furthermore, it was found that the deposition onto nickel foam as substrate and curent collector led to decrease of the ion transfer resistance so that its specific capacitance of a NiO film had high value than NiO nano flake powder.

It is the youth period that the personality is shaping gradually. The residential environments have influence on the young ego. Especially residential design should include more youth friendly design elements than any other facilities. The purpose of this study was to provide the youth friendly design elements about the space design of apartment through analysis of youth's needs. This study was progressed to the survey method about five districts of apartment design competitions in 2007. The collected cases are analyzed by using statistics software SPSS for windows release 11.0. The result of the study was as below. First, the youth satisfaction of current residential space got more satisfied as floor space got larger. Second, most of youth uses them own room that is satisfied with their floor space for sleeping, inviting friends, studying, playing activities. Third, generally youth preferred to place their own room not far from the restroom, but the result of distance between master room and entrance was classified depend on sex, personal inclination, and residence environment, also generally satisfied with volume of their room. Fourth, for the restroom, although it is too small that satisfied with bath facilities relatively. And cast, youth's preferred room for extra was 'movie/music room', 'game room' and 'dress room' which is higher preference than 'study room'.

The aim of this study was to recognize the need of three generation family house that is traditional house type of Korea. First, the pre-research analysis method was used for this study. And then, there are three type's grouping like those are as follows; 1) Recognition of three generation family house. 2) Type of three generation family house. 3) Plans of three generation family house. The analysis results are as follows; If the conditions are better than now, recognition is positive. Type are living together and next doors type can direct access. Some standart plan is been about room's number, house's area, bath's number and so on. Second, try to compare plan - this plan already has been used building - with standard plan. The compare result are as follows; three generation family houses - be used by whom - do not apply to standard plan. Almost houses have a three room that is less than the standard plan. All houses have a number of two bath that is less than the standard plan too. Condition of consideration is suitable to ages in next door type, but in case of living together type that consider user whom is use the inner room. Separation of entrance distinguish between the living together type and the next doors type. In case of living together type Dining with Kitchen room's number is one, but the next doors type have the number of two.

Effects of current density, electrodeposition temperature and solution pH on properties of Cu thin films electrodeposited from pyrophosphate bath were investigated. Current efficiency was decreased with increasing current density and increased with increasing temperature. But solution pH slightly influenced on current efficiency and current efficiency was measured to be above 90% at both room temperature and $55^{\circ}C$. Residual stress of Cu thin film electrodeposited at room temperature was decreased with increasing current density, while current density reaches to 60 $mA/cm^2$ or more, stress became close to zero. Cu thin films electrodeposited at $55^{\circ}C$ exhibited the residual stress range of 0~40 MPa. At room temperature, dendritic surface morphology was observed above the current density of 30 $mA/cm^2$ and at $55^{\circ}C$, above the current density of 100 $mA/cm^2$. Cu thin films electrodeposited from bath solution with room temperature and $55^{\circ}C$ mainly consisted of (111) peaks. Specially, Cu thin film electrodeposited at 30 $mA/cm^2$ and $55^{\circ}C$ exhibited strong preferred orientation of (111) peaks.

Electroless copper plating method using an alkaline bath have been employed in copper coating of the (LM)Ni4.5Co0.1MnO.2A10.2 hydrogen storage alloy powders for electrode preparation. The plating were conducted without any pretreatment of alloy powders. For the preparation of the electrodes, about 0.12g of the copper coated alloy powder (copper to alloy ratio 1/3 by weight) was compacted with pressure of 6 tons/cm2 at room temperature. The disk-type compacts had a diameter of 10mm and thickness of about 0.24mm. The electrode characteristics were examined through SEM observations and electrochemical measurements in a half cell. The electrochemical measurement showed that the maximum discharge capacity of the electrodes prepared by using alkaline bath were 245mAh per gram of coated alloy (327mAh per gram of alloy) and appeared a considerable degradation with increasing number of cycles. The decrease of the discharge capacity after 100 cycles was about 30% It can be suggested that, with a slight of improvement, this electroless copper plating method could be applied to the preparation of the rare earth-nickel based alloy electrode.
