Due to the belief that housing for university students is uniform materialistic and non-human, a variety of needs and preferences of the residents is becoming more important. In order to more positively identify the user's emotional needs, a design that meets the needs of the resident's living space is absolutely necessary. The purpose of this study is to group the sensibility types of university students, to analyze the preferred interior image and interior design elements, and then to understand the preferred characteristics according to sensibility type. To collect the data, a survey method was used for 224 university students in Seoul and the metropolitan area. The data analysis used SPSS PC 14.0 to find the frequency, t-test, chi-square, factor analysis, and cluster analysis. The results of the analysis are as follows: First, sensibility types were segmented into four groups including 'Unique & Elegant', 'Static & Tidy', 'Warm & Comfortable', and 'Characteristic & Free'. Second, the preferred interior image was the Minimal-Dandy-Natural Image, the preferred floor_material was wood, and the preferred wall_material was marble. Third, there were different interior preferences according to each type of gender & sensibility.

In this study, physical characteristics of cement and/or concrete materials that are typically used for energy-foundation (EF) structures have been studied. The thermal conductivity and structural integrity of the cement-based materials were examined, which are commonly encountered in backfilling a vertical ground heat exchangers, cast-in-place concrete piles and concrete lining in tunnel. For this purpose the thermal conductivity and unconfined compression strength of cement-based materials with various curing conditions were experimentally estimated and compared. Hydration heat generated from massive concrete in the cast-in-place concrete energy pile was observed for 4 weeks to estimate its dissipation time in the underground. The hydration heat may mask the in-situ thermal response test (TRT) result performed in the cast-in-place concrete energy pile. It is concluded that at least two weeks are needed to dissipate the hydration heat in this case. In addition, a series of numerical analysis was performed to compare the effect of thermal property of the concrete material on the cast-in-place pile.

Since 1990s, increasing number of public arts have been installed in housing projects in Korea. Most of them were made of granite, bronze and stainless steel and were sculptures as well. Then it resulted in monotony. New technology and community need various Dials in material and genre of Public art. The author wonders if people really want granite sculpture, so started the study of public arts in housing projects. Unfortunately most of people related public art wanted granite sculpture. But there were some hope in survey. They wanted the other genre and material like ceramic wall, art fountain and landmark tower. This means that they care about real world like vandalism and Product Liability, but also want more fantastic and beautiful world in the second step. Recently, the facades of apartments are changing rapidly as more diverse materials in their forms, textures, and colors. And landscape designs are changing their clothes in every second as well. According to these flows public arts in apartments needs more diversified trial within genres and materials to avoid monotonous outdoor.

The die casting process was used to manufacture a alternator housing for automobile. Specially automobile parts were required light and hight strength. Therefore simulation have been carried out die casting process of the alternator housing. In this paper, we investigated about characteristics of the die casted alternator housing the HPDC(High Pressure Die Casting) process. Also we designed the die casting die with the simulation results of the alternator housing. The MAGMAsoft and Auto-CAD was used as computer simulation and design code and used material was ADC12(Aluminum Die Casting Alloy). We present the results of filling behavior and design of die process of the alternator housing cast. The result obtained about filling behavior and design of die of the cast showed good agreement with test result.

This research is about the Korean private residence as the actual housing published in Kuchie, 'Chosun and Architecture'. Research about the Korean private residence during the Japanese colonial period is important to find out the influence of foreign culture on Korean housing during that period. This research is necessary to reveal the tendency of modernization of Korean housing and how the foreign cultural relationship transformed and applied to the Korean housing. This research was carried out mainly on the 16 Korean private residences published in 'Chosun and Architecture'. The main subject of this research is to analyze the architectural floor plan, building material and heating facilities etc. Other important themes of the research are the practical side of actual housing plan, interior furnitures and fittings, electrical fittings and the classification of life style.

The purpose of this study is to identify the homelike design characteristics of elderly housing facility. To investigate what the preference of physical design characteristics are, interview was done by unstructured questionnaire to 30 middle aged and middle income group housewives living in Seoul. It was identified that preferred homelike physical characteristics of the houses were composed of 4 themes, housing types, building appearences and garden, floor plan and natural and social environments of its location. Their desirable housing standard was amenity which is the highest level of home environment. In their later life, they wanted to live in vicinity of Seoul to enjoy cultural benefits of the city and active outdoor activities in sunny, natural suburban environment. They liked a spacious, clean and bright color with natural material furnishings. Each architectural design expression of 4 themes was suggested.

This study is concerned with the survey methods to approach a research into ‘local architecture’ in korea. Local materials for architecture can be classified into local buildings, local documents, local conditions. To perform the survey research into local architecture effectively, it demands a reasonable survey methods depending on the characteristics of materials for architecture, and we have to give careful consideration to the survey process, the materials collecting, the materials noting and reporting. The typical survey methods of local are presented in this article.

압전형 가속도 센서(AMP 내장형 PA-01)의 전원 NOISE 영향은 가속도 센서의 금속부 구조 및 내장된 임피이던스 변환기의 역할을 하는 내장 AMP의 차페성 저항등에 원인에 있었다. 이 전원 NOISE 영향을 저하시키기 위하여 가속도 센서부의 UNIT CELL과 HOUSING 본체와의 절연 저항을 600㏁ 이상 되게하여 절연성 향상 및 임피이던스 변환기의 차페로 인하여 전원 NOISE 영향을 1/200∼1/2000 정도로 감소시킬수 있었다. 이때 UNIT CELL과 HOUSING 본체와의 절연 처리오 NOISE차페효과로 1/20 정도로 줄일 수 있었으며, 내장 AMP 차페로는 1/10∼1/100의 노이즈 차페효과를 얻을 수 있었다.

The purpose of this study is to investigate the fatigue safety and deformation of housing in plate rolling process. For this, we carried out 3-dimensional FEM analysis for housing considering design variations of housing structure. It showed that the housing with rounds under a column is benefits to control thickness accuracy of rolled material, due to smaller elastic deformation and maximum effective stress. Also, we calculated the fatigue safety factors, the ratios of the pulsating equivalent fatigue limit to the maximum tensile stresses analyzed using the equipment force and normal rolling force.
