The purposes of this study were to identify the needs for ubiquitous home services in residential environment of elderly single or elderly couple households living without children and also to analyze the differences of the needs according to their demographic and housing characteristics. For this study, a literature review and field works on ubiquitous home services for older people were performed. Also, 1 to 1 interview by using the questionnaire which was developed by the researchers in this study was conducted and 270 elderly residents in Seoul and Gyeonggi-Do were responded. Seventy-one ubiquitous service items which were adopted to home electronic appliances and furniture for older people were developed for 1 to 1 interview questionnaire. The major findings of the study were as follows: the elderly residents expressed highest need for ubiquitous home service items related to safety and health issues. Among ubiquitous service items applied to gas stove, vacuum cleaner, TV, telephone, sofa and toilet, the items related to safety and health aspects were most needed. And residents' income level and health status were the two major variables to show group differences in the need of ubiquitous home services. In other words, the elderly residents who were high income and frail tended to have the highest demand for ubiquitous home services adopted to home electronic appliances and furniture.

To find out abnormal electrical conditions, periodic inspections for residential houses are being performed every 3 years. According to data from KESCO, the number of uninspected houses is rising as the number of empty houses during normal working hours is rising by dramatic increase in the number of nuclear families and double income families. As a result, potential hazards are increased by them. In this paper, a model of a national electric safety network is presented. In the model, functions for ubiquitous environments were partially realized.

This paper documents research carried on the University students who are potential residents of the city to find out their preference for the ubiquitous residential functions, and categorize based on the life style to find out difference of their preference on ubiquitous residential functions. A survey was conducted on 324 university students in Gwangju city. The students were selected through purposive sampling and quota sampling by self-administered questionnaire sheets. The analysis analyzing methods using SPSS/PC 12.0 are frequency, percentage, factor analysis, cluster analysis, $x^2$(chaisquare)-test and one-way ANOVA (analysis of variance). For the survey, lifestyle types were categorized as: These are classified based on the analysis of facts regarding characteristics of student's lifestyles that are divided into nine types of facts and then make the four types through the cluster analysis as below. Energetic life type, Inactive life type, Family-oriented life type, Thrifty and Personality-oriented life type. The residential function of Ubiquitous is classified as Safety, Convenience, Comfortableness, Information, Health, Leisure and the residential space is divided into bedroom, livingroom, kitchen, bathroom. Considering the preference aspects for Ubiquitous residential function, among the bedroom, living room, kitchen, and bathroom, University student seek for safety from the living room, Convenience from the kitchen and Comfortableness from the living room, bedroom and kitchen. For Information, bedroom is most preferred among the bedroom, living room, and kitchen. For Health and Leisure, bedroom is preferred between bedroom and living room. In terms of the difference about the preferences for ubiquitous functions based on the four types of lifestyles; The Thrift-oriented type is commonly preferred to the Inactive type among the bedroom, living room and kitchen. The Family-oriented and the Thrift-oriented type were preferred to the Energetic and Inactive types in the bathroom. Also, in the entire residential space, the Ubiquitous functions is most preferred by the Thrifty and Personality-oriented life type.
