Korea is a fast growing aging society. Growing older population causes various social issues and problems in many aspects. Housing issue is one of them and residential modifications for improving safety and independence for older residents are very important factor for Aging in Place. Under those social circumstances, the purpose of this study was to analyze the residential modification demand by the elderly on the application of ubiquitous home services. Respondents were the residents those who were over 55 years old, were living in a singe detached house and were able to use a computer. The major findings of this study were as follows: the results on current situations and demands for residential modifications showed that respondents already made mean of 4.9 home modification items and wanted to make mean of 12.4 items out of 21 residential modification items. The results on demands for the ubiquitous home services was relatively high(mean 3.82). This study can be an important information which is able to improve the quality of life by providing effective residential modifications for older population to help them ultimately safe, convenient, and independent living.

유비쿼터스 컴퓨팅 환경은 오늘날 인간생활 행태의 변화뿐만 아니라 미래건축 공간에도 큰 변화를 가져오고 있다. 그 중에서도 인간의 가장 기본적인 생활환경인 주거 공간의 변화는 빠르게 이루어지고 있다. 지능형 홈, 사이버 아파트 등의 새로운 미래주거 공간이 나타나고 홈네트워크 시스템을 이용한 다양한 유비쿼터스 서비스가 적용되고 있다. 그러나 거주자를 위한 유비쿼터스 서비스가 공간에 적절히 적용되지 않는 사례가 발생하고 있고 수요자 요구와 관련 없이 서비스가 설계되어 있어 효율성이 떨어지는 문제점도 나타나고 있다. 이는 현재의 홈네트워크가 IT 업계가 제공한 솔루션과 기기 중심으로 서비스가 개발되고, 공급자 위주의 기능의 편리성을 위주로 제공되고 있기 때문이며, 주택을 잘 알고 있는 건설인과의 협업이나 최종 사용자의 기호가 고려되고 있지 않기 때문이다. 더욱 중요한 것은 초기 디자인 단계에서 이러한 문제점들이 수용되고 있지 못하고 공간 디자인과 서비스 개발이 유리화되어 선 시공 후, 서비스를 끼워 맞추기식으로 계획하고 있기 때문이다. 본 연구는 서비스 개발의 관점에서 접근하여 공동 주택의 초기 디자인 단계에서 수요자가 원하는 서비스를 공간에 적용하여 부합되는지를 살펴보고, 이에 따라 적절한 미래공간을 디자인 할 수 있도록 하기 위하여 공간정보 데이터베이스를 기반으로 한 공동주택 유비쿼터스 서비스 개발을 위한 기초 연구에 그 목적을 둔다.

Finite element simulations are being widely used to increase the efficiency and effectiveness of design of bulk metal forming processes. In such simulations, proper consideration of friction condition is crucial in obtaining reliable results. For this purpose, tip test based on backward extrusion was proposed recently. In this lest, a cylindrical billet is positioned in a shallow groove of a counter punch for centering purpose and formation of a radial tip is induced on the extruded end of the workpiece. In this study, the effect of centering groove on tip test was investigated. The quantitative ratio of the shear friction factors between the punch and die was numerically determined depending on the shape of centering groove. Also, surface expansion and pressure distribution along the punch and die were considered in order to better understand the reason that friction condition at the punch compared to the one of die was more severe.

고정된 위치에 있거나 이동중인 수신자들에게 고품질의 멀티미디어 콘텐트를 제공하기 위하여 지상파 DTV를 위시하여 디지털위성방송, 지상파 및 위성 DMB 등 다양한 방식의 방송 서비스들이 가까운 장래에 우리 생활의 일부분이 되리라고 예견되고 있다. 이러한 서비스들은 방송과 통신의 융합환경에 맞추어 맞춤형 방송의 형태로 이용될 것이며, 이는 텔레매틱스나 홈 네트워크 등과 같은 다른 정보 전달 체계와 결합하여 보다 고도화된 정보사회의 중심적인 역할을 할 수 있을 것이다. 본 논문은 방송 통신 융합 환경에서의 DTV의 주요한 한 가지 역할로서 DTV 기반의 흠 네트워크를 제안하고, 그러한 흠 네트워크에서 멀티미디어 콘텐트를 공유하기 위한 두 가지 방안에 대해서 논한다. 첫 번째 방안은 홈 서버 기능을 하는 DTV PVR에서 단 한번의 복호 과정과 스케일러블 코딩 과정을 통하여 가정 내의 모든 기기들이 실시간으로 방송 콘텐트를 공유하는 방법이고, 다른 한 가지 방안은 전체 방송시스템 비디오 부호화 규격을 스케일러블 부호화 기법을 적용한 단일 표준으로 통합하는 방안이다. 본 논문을 출발점으로 하여 이와 같은 논의가 활발하게 이루어지기를 기대한다.

The purpose of this study is to propose our direction of long-tenn care facility for elderly. The long-tenn care insurance plays an important role for human well-being. The functional and architectural changes of Japanese elderly care facilities have been analysed in order to predict changes in Korean welfare facilities. In Japan, Unit-care and private rooms are essential elements after reforming welfare facilities for aged. This study proposes components of unit-care through the analysis of 20 facilities for the aged. A unit is basically consist of private rooms, rest room, public living area, kitchen, health care service station, and bath room. Besides, smoking room, tea room, public terrace, guest room, court yard, and so on can be added. A unit can be connected with other unit by semi-public spaces or can be independently organized. This relationship has been classified into 2 types; Open unit type and Separated unit type.

The purpose of this study was to propose ubiquitous housing environment based on older residents' needs for ubiquitous(UT) home services. For this purpose, at the previous study which was the first stage of this study, UT home services by each elderly household based on spouse, income level, and health status were identified and this study finally proposed UT home services by each elderly household type according to residents' level of needs for UT home services. One to one interview with a structured survey questionnaire and illustration was implemented and 204 older residents who were composed of one of six elderly household types were responded. Among 6 types of elderly households, type 2 and 6 were the groups which had higher needs for various kinds of UT home services. Economic status and their health status were the key factors to determine their needs for UT home services. Type 4 and 7 were the groups to express their lower needs for UT home services due to their lower income level and good health condition. Ultimately, two floor plans for type 4 and 5 elderly households were developed to show applicable UT home services in each room of the house.

This study analyzes the locution of television home shopping show hosts for apparel products with a focus on the selling points and vocabulary use. A qualitative content analysis was conducted for 15 recorded home shopping shows selling women's overcoats and jackets. The results are as follows. First, 8 dimensions of selling points were revealed: Promotions, brand popularities, the experiences of shopping hosts, fashion trend information, conformity motivation and suggestion, intangible attributes, tangible attributes, and compared/leading differences. The most frequent selling point was tangible attributes. Following this were, promotions, conformity motivation and suggestion, compared/leading differences, intangible attributes, brand popularity, the experiences of the shopping hosts, and fashion trend information in order. The selling points were almost proper to decrease the perceived risks of home shopping consumers. Second, shopping hosts frequently used the clothing terms without any expatiations and used loan words (foreign language terms) instead of the direct Korean translations. In the conclusion, the development of a marketing strategy focusing on shopping host management is suggested.
