The purpose of this study was to investigate the middle-aged housewive's background characteristics influencing on the preference of elderly housing, depending on four aging-situations. The characteristics of the elderly housing dealt in thes study were geographical location. specially planned feature for the elderly, house type, the size of housing, housemate, the distance from the living quarter of their children, and whether they want to live in the rental house. The subject were 526 middle-aged housewives from middle-income householde living in the capital area. Questionnaires were sent through mail to the householde which tesponded positively on the information brochure about this study sent before. The characteristics of the elderly housing which perferred to was influenced by their age and socio-economic status, such as schooling, job, income, and the size of housing. This result suggests that it must be considered to develop various types of the elderly housing depending on socio-economic status.

The purpose of this study was to set related variables for leadership measurement in the leader of a community organization as an effort to Community development constantly. Therefore, in this study, first, various theories on leadership were reviewed. Second, approaches and variable relationships were reviewed by leadership theory study. Third, leadership measurement variables were set based on Bass's Transformational theory, one of new trend theory, to measure the leadership of the community organization leader. As a follow up, clear and scientific analysis, through empirical analysis, based on the variables set in this study will be made to measure leadership of a community organization after creating investigation tools based on the variables set in this study A literature study was mainly used. 'Human Behavior' by Dr Han-geom Lee, 'Leadership Theory' by Eung-seop Shin, many other related books, articles of the Human Relation Organization Association, and theses and Bass's writings. Major findings of this study, through the literature study, were as follows. As conventional leadership theories, characteristics theory, behavior theory and situational leadership theory were proposed. First, characteristics theory searches the characteristics of an effective leader. It proposes that effective leaders and ineffective leaders have different characteristics, respectively. Therefore, it proposes to study the leader's characteristics. However, there is not a flexed definition for leader's characteristics. Scholars make different definition on leader's characteristics, and they are very subjective. Thus it cannot be a valid theory. Second, behavior theory describes how the leader behaves to his fellows. It studies leader's behavior focusing on what type and what combination is the most effective in all situations. However, it has weakness in that it focuses on a leader's behavior only, and ignores the situational features. Third, situational theory describes the relationship between leadership type and situation. It suggests that there is not a single leadership style that can suit all situations. It emphasizes the relationship between leadership type and situation. Although situational theory considers more variables than characteristics theory or behavior theory, it also sees situations as static and flxed. Although Fiedler's theory tried to comply with situations, he did not analyze interactions between a leader and his fellows.

This study was made to determine the factors involving personal exposure levels of nitrogen dioxide for housewives living in urban area in two seasons, winter and summer. Nitrogen dioxide was measured with a small passive sampler containing triethanolamine. The samplers were set for 24 hours at three points. They were places: on the collar of the housewife to investigate the personal exposure level, near the TV in the living room (indoor level), and near the porch of their house (outdoor level). The subjects recorded the times of cooking using a gas range, using a kitchen ventilator, passive smoking, kerosene heater, total number of minutes at an open window, going out of home, etc.$\ldots. There was an apparent increase in personal exposure level in the case of the unvented heater and also an increase by cooking on a gas range. There was no marked increase in the other situations. There was an increase in the indoor level by cooking on a gas range, only in western style cooking in the winter season. Through these observations, we concluded that personal exposure level of nitrogen dioxide was strongly related to indoor nitrogen dioxide level, and factors involving indoor nitrogen dioxide level seemed different between winter and summer. The most significant difference in nitrogen dioxide level was indoor pollution in the winter and the outdoor environment in the summer. The maximum personal exposure level appeared in the western and tenement house in the winter and the traditional korean house in the summer.

This paper proposes a system architecture for USN with a service robot to provide more active assisted living services for elderly persons by monitoring their mental and physical well-being with USN environments at home, hospital, or silver town. Sensors embedded in USN are used to detect preventive measures for chronic disease. Logged data are transferred to main controller of a service robot via wireless channel in which the analysis of data is performed. For the purpose of handling emergency situations, it needs real-time processing on gathering variety sensor data, routing algorithms for sensor nodes to a moving sink node and processing of logged data. This paper realized multi-hop sensor network to detect user movements with biometric data transmission and performed algorithms on Xenomai, a real-time embedded Linux. To leverage active sensing, a mobile robot is used of which task was implemented with a priority to process urgent data came from the sink-node. This software architecture is anticipated to integrate sensing, communication and computing with real-time manner. In order to verify the usefulness of a proposed system, the performance of data transferring and processing on a real-time OS with non real-time OS is also evaluated.

In Korea, welfare needs brought on by the rapidly growing of elderly population. Also, the senior group with spare time, wealth and health is increasing. Currently, the people have known about needs welfare system for improving quality of life during senescence personally and socially. In addition to the senior friendly industry, having distinction with simple approach medical services, will be great expanding after 2010. And there will be a new welfare services plan supporting long term care insurance for senior citizens. But we don't have prepared systematically organized senior friendly industry and products yet. So, the purpose of the study is to analyze systematically the classification characteristics of the senior friendly products according to the difficulty of daily living for senior citizens. Above all, the study finds out the senior friendly products characteristics according to the consumer's various situations about health and housing space. Therefore the result of the study reveals that the simulation guidelines for choosing the products depend on the customer's needs are essential and useful to improve senior friendly industry. And the post evaluation data of senior friendly products would be put to practical use in the industry.

The purposes of this research are to find out the standards which mothers consider seriously when choosing a day care center and mother's perception for the quality criteria of day care center, and to estimate the differences of these according to region. The sample consisted of 568 mothers with children using day care center located at the city of Taegu and Dalsung Gun. Collected data were analyzed by frequency, Percentage, chi-square, t-test, chronbach's $\alpha$. The results are summerized as follows : 1. In mother's perception for the quality criteria of day care center, the mothers living in the large city perceived more importantly in staff qualifications, administration - evaluation, staff- parent/staff- child interaction, curriculum, staffing, physical environment nutrition, health and safty than mothers in rural community. 2. In the importance classified by domains of the quality criteria of day care center, there were statistically significant differences according to the variable of region in staff qualifications, staff-parent/staff-child interaction, curriculum, staffing, physical environment 3. Given the present situations (income, transportation, location of workplace, etc.), when mothers choose a day care center, generally, staff-parent/staff-child interaction was the most important factor. And according to region, the distance to workplace or home was the most important factor in the case of mothers living in the large city, on the other hand, staff-parent/staff-chad interaction was the most important factor in the case of mothers living in rural community when mothers choose an ideal day care center, generally staff-parent/staff-chad interaction was the most important selection standard, and there were not remarkable differences according to region.

This study investigates differences by type of caregiving using data on three groups of caregivers, 177 from home stay situations, 189 from day care centers, and 138 from nursing homes. First, the result shows that characteristics of both caregivers and elders differ by type of caregiving. Second, caregivers in the home stay situation have the highest caregiving burden of the three groups. Third, from examination of the related variables, the caregiving burden of home stay caregivers is affected by family income, caregivers' health, type of job, and whether or not the elder has symptoms of dementia. Also, the study reveals that emotional services for elders reduce the aggravation of family relations and economic burden, but that instrumental services highly increase economic burden. It reveals that caregivers of elders in day care centers, especially those who are in bad health, are more likely to experience feelings of constriction, aggravation of family relations and economic burden. On the other hand, caregivers who receive more emotional services have better experiences in family relations, including relations with the elder. In case of the elders of nursing homes, if the main caregiver is a daughter-in-law, aggravation of family relations is higher than if the main caregiver is a spouse. Finally, the caregiver's burden is affected by their own health and income, and by whether the elder has symptoms of dementia or stroke.

Current discussions on productive aging are going towards the direction to sustain a social productivity and lessen a social burden, and this becomes distinct as it gives a strong value to the activity and independence of older people. This study highlights complex situations of productive activities in the group of older people by analyzing the survey of Among the productive activities of older people, two areas of activities - paid labor and social support - were interpreted differently according to their economic stability, spontaneity and family relations. This difference becomes more remarkable in the analysis on life satisfaction of older people. In paid work, which is the most common productive activity, there was a big difference in life satisfaction between those who work spontaneously and those who work inevitably to make a living. And in the comparison of life satisfaction for those who participate in homemaking and care working according to their economic situations and family relations, those who were unsatisfied with family relations showed lower life satisfaction.

As of 2010, apartment occupies more than half of all houses in Korea. It took just half a century since 1960 when apartment was introduced to ordinary people for the first time. The apartment has spread over the nation very swiftly since then. This phenomena needs more inclusive explanations than the investigations into the government's policies or economical situations. Without satisfaction and consensus of people, the universal spread of apartment might be fairly unrealizable. In this vein, the research and analysis has been performed in order to grasp the picture of everyday life's discourse based on the related articles from five major newspapers and five women's magazines during 1960~1989. From the articles' discourses we tried to understand how modern apartment has been accepted and evaluated through people's living life in it. First, the discourse of living life was generated mostly by housewives through the comparison between apartment and traditional house. Second, the most influential aspect of apartment's popularization was the convenience of efficient housekeeping system by modern equipment and home appliance installed in apartment. This efficiency could allow housewives to perform various urban activities such as work, shopping, and simple going out. Third, the satisfaction from efficiency and privacy brought about a sense of alienation at the same time. As a result, the rapid proliferation of apartment in Korea could be attained not only by the institutional driving forces but through the fulfillments of Korean people's housing needs from modern everyday life.

As the number of elderly people living alone increases, the frequency of fall accidents is also increasing. Falls are a threat to the health of older adults and can reduce their ability to remain independent. To solve this problem, we need real-time technology to recognize and respond to the critical condition of the elderly living alone. Therefore, this paper proposes a modified fall detection algorithm based on YOLO-KCF that can check one of the emergency situations in real time for the elderly living alone. YOLO can detect not only the detection of objects, but also the behavior of objects, namely stand and fall. Therefore, this paper can detect fall using the ratio of change of boundary box between stand and falling situation, and this algorithm can improve the shortcomings of KCF.
