The purpose of this study was to examine the meaning and essence of the life of elderly men living alone in public rental housing. Among the phenomenological study methods, the present study used the analysis method proposed by Giorgi(2009). The study participants included 10 elderly men living alone in public rental housing who were recruited through network sampling. The research data were collected through in-depth interviews conducted twice for each person. The results showed that living alone as an elderly man is likened to standing against cold wind out in the wilderness of the world, with living alone deemed a power game between life and death. For the participants, public rental housing is a fence that separates them from the world-the final station of a wandering life. For common people, public rental housing is a stable fence, but for the participants, it is the location of a double-edged solitary life out in the wilderness where the instincts for survival and death play a tug of war. Based on the study findings, the researcher discussed and provided suggestions for psychological housing stability, the disparagement of the elderly in mass media, and countermeasures against psychological isolation.

The purposes of this study were to determine the actual state of indoor environments of solitary elderly houses in the rural district during winter and to analyze the relationship between the influencing factors and indoor physical elements. Field surveys consisted of measurements of physical elements, observations of living factors, and resident's responses in interviews. Field surveys were carried out in 4 houses from $28^{th}$ of February to $2^{nd}$ of March 2008. The elements measured were air temperature, relative humidity, floor temperature, seating-place temperature, CO2 concentration, CO concentration, and illumination. The results showed that the average indoor temperature for houses was $13.5{\sim}22.5^{\circ}C$, relative humidity was 30.6~55.4%, floor temperature was $13.9{\sim}24.0^{\circ}C$, temperature when seated was $27.6{\sim}51.1^{\circ}C$, $CO_2$ concentration was 1434.6~3305.5 ppm, CO concentration was 2.8~8.4 ppm, and illumination was 31.0~96.7 lux. The residents' clothing values were 1.10~1.78 clo. The environment was evaluated as being in an unsuitable state, and it was revealed that the main reason was the lack of heating and ventilation.

The purposes of this study were to determine the actual state of indoor environment and to analyze the relationship between the living factors and indoor physical elements in solitary elderly houses at rural district during winter. The field surveys were consisted of measurements of physical elements, observations of living factors, and interviews of resident's responses. The field surveys were fulfilled in 4 houses from February to March 2008. Measuring elements were air temperature, relative humidity, floor temperature, seated place temperature, $CO_2$, CO, and illumination. The results showed that the average of indoor temperature for houses was $13.5{\sim}22.5^{\circ}C$, relative humidity was $30.6{\sim}55.4%$, floor temperature was $13.9{\sim}24.0^{\circ}C$, seated place temperature was $27.6{\sim}51.1^{\circ}C$, $CO_2$ was $1434.6{\sim}3305.5ppm$, CO was $2.8{\sim}8.4ppm$, illumination was $31.0{\sim}96.7lux$. The residents' clothing values were $1.10{\sim}1.78clo$. Most of the residents' subjective responses were in discord with the physical elements. It was evaluated to be uncomfortable state, and the main reason was revealed lack of heating and ventilation.

The purpose of this study is to find the housing affordability of elderly household according to household types and housing tenure and to contribute to desirable elderly housing policies. The data from the 2010 Korea Housing Survey was used for the analysis of this study and the final sample included 6,780 elderly households. The results of this study are summarized as follows; It was found that all kinds of elderly household for housing affordability were affected by income, residence period, housing location and size of house. And housing location was a highly influential factor. Besides, female elderly house-owners and male elderly renters living alone were likely to have higher housing cost burden. And if elderly renters households suffer more financial burden, they had have higher housing cost burden. It is implies that desirable elderly housing polices by government need to consider elderly househod's diverse characteristics in aged society.

The study aims to furnish the data for the study of invigorating communities of various ages including old people living alone. Furthermore, it seems that the laddering method and kj method can be useful for the study of various attitude survey. This study attempted to extract necessary factors for space for community behavior of elderly people living alone using laddering survey method and KJ rule on a sample of elderly people who live alone in three different rental housings. The keywords that were drawn from the perception survey through laddering were divided into small, middle and large classification using KJ rule. Mostly identical keywords were extracted in the three complexes, implying that there is no difference of perception among the three complexes in this survey. According to the large classification where KJ rule was applied, there were six necessary factors for space for community activity of elderly people living alone in rental housing including spatial consideration, communication, resting space, nature-friendliness, health promotion and Secure identity, which were the same for all of the three complexes.

This paper describes a remote system to monitor the circadian behavioral patterns of elders who live alone. The proposed system was designed and implemented to provide more conveniently and reliably the required functionalities of a remote monitoring system for elders based on the development of first phase prototype[2]. The developed system is composed of an in-house sensing system and a server system. The in-house sensing system is a set of wireless sensor nodes which have pyroelectric infrared (PIR) sensor to detect a motion of elder. Each sensing node sends its detection signal to a home gateway via wireless link. The home gateway stores the received signals into a remote database. The server system is composed of a database server and a web server, which provides web-based monitoring system to caregivers (friends, family and social workers) for more cost effective intelligent care service. The improved second phase system can provide 'automatic diagnosis', 'going out detection', and enhanced user interface functionalities. We have evaluated the first and second phase monitoring systems from real field experiments of 3/4 months continuous operation with installation of 9/15 elders' houses, respectively. The experimental results show the promising possibilities to estimate the behavioral patterns and the current status of elder even though the simplicity of sensing capability.

This paper presents calorie expenditure prediction model of daily activity of elderly living alone for LBS(Location Based Service) applications. The proposed method is to describe the daily activity patterns of older adult using PIR (Passive InfraRed) motion sensors and to examine the relationships between physical activity and calorie expenditure. The developed motion detecting system is composed of a sensing system and a server system. The motion detecting system is a set of wireless sensor nodes which has PIR sensor to detect a motion of elder. Each sensing node sends its detection signal to a home gateway via wireless link. The home gateway stores the received signals into a remote database. The server system is composed of a database server and a web server, which provides web-based monitoring system to caregivers for more effective services. The experiment results show the adaptability and feasibility of the calorie expenditure model.
