Purpose: Korean society has already entered an aged society but there aren't many evidence-based studies on the elderly-friendly design elements in the apartment environment, which is the main residential type in Korea. The main purpose of this study is to verify the necessity and expandability of the outdoor environment design in the public rental apartment complex through the evaluation of the effectiveness and satisfaction of SMG(Seoul Metropolitan Government) Cognitive Health Design Project in GR 1 apartment complex. Methods: The research subjects were GR 1-complex as experimental group and the nearby Wolgye Deer 1-complex as control group, both public rental apartment and located in Seoul. As a research method, the survey was conducted before and after the implementation of SMG project for residents of the apartment. A total of 200 preliminary surveys and 203 post surveys were conducted. Results: As a result of this study, residents' accidents related safety have decreased, and both the frequency of use and satisfaction of most facilities have increased. It is noteworthy that the increase in cognitive items in the post-survey. Also, 74.5% of the residents evaluated that the complex was better to live after the project was implement. Implications: The fact that the preliminary surveys were not conducted for the same person is considered as the limitation of the study, but it is meaningful in that it systematically assesses the effectiveness of the project on the cognitive health of the outdoor residential environment towards age-friendly city.

In Korea, traffic accidents between pedestrians and vehicles in 2015 account for 38.8% of all accidents. This study proposes a system design that can measure the risk of conflict between a vehicle and a pedestrian. Firstly the systemdetect and estimate the position, speed, and directional data of the vehicle and the pedestrian. And then it estimate the conflict point between a vehicle and a pedestrian. The risk of conflict is quantified by estimating the pedestrian safety margin (PSM), which is the time difference between the arrival of the pedestrian at the crossing point to the point of conflict and the vehicle approaching the point. In this system each data is acquired through an external monitoring based evaluation module and an individual wearing module. In the future, such a system can be used for decision making such as the design of road hazard improvement facilities and the designation of the elderly protection area.

Nursing Homes are different from other medical facilities, because they have a living space. And most of residents in a nursing home have dementia, therefore nursing homes are in control of outdoor activities for resident's safety and most of residents live in the living room at the daytime. The purpose of this study is analysis of spacial behaviors of residents in the living room, and reflection of the analysis into the architectural plan of nursing homes.There are two activities, individual activity and social interchange activity, in a living room and the role of a living room is semi-private space that includes both of them. Most numerous activities are watching TV and take a eat. Activities are different in accordance with the position at the living room. Individual activity and social interchange activity is same ratio in the middle and the ratio of social interchange activities are more than individuals in outside of living room. but alcove use of private.The types of living rooms are distinguished by combination of functions of livingroom, activity-room, and diningroom. The activity of use of residents have been shown different phases following the types of livingroom. The type of combination has been seen high rate of use and private activities and social communications are expressed evenly. The type of mixing has been seen low rae of use, but two activities, the above, are equal. The type of separation has been seen not only low rate of use, but also there has been only private activities.

A small number of high cost patients usually spend a larger proportion of scarce health resources. Korea is no exception. Under the national health insurance, 12% of the insured persons have consumed approximately half of the national health insurance expenditures. Therefore, it is necessary to identify the characteristics of the high cost patient group, if we would like to reduce them. This study has defined high cost patients as those who have spent one and half million won and over per 6 months. The study reveals that high cost users are those who have a longer length of stays(LOS), 40days of LOS in the 6 months, have multiple admissions, 2 to 3 admissions per 6 months and are the elderly patients. They have spent 814.126won per on the average, and commonly suffered from malignant neoplasms, circulatory diseases, fracture, diabetes mellitus, etc. Unlike the case of western developed countries, early readmissions are not the major causes of high cost spending in Korea. Undoubtedly, a lengthy admission is the main cause of large spending. Health policies should vigorously be explored to respond appropriately. There are evidences that hospital beds are often misused. As the Korean health care system is lacking in a mechanism of patient evaluation under the fee-for-service remuneration system, an idea of progressive patient care needs to be tested. The Goverment should set up health policy to diversify the role of long-term care facilities and encourage people to establish them. Further studies are needed to identify factors influencing large medical bills necessary for formulating the health policy on cost containment.

This study was conducted to understand influential factors in determining the advance directive attitudes of elderly patients. Structured survey questionnaires were distributed using a convenience sampling method to the residents of long-term-care facilities. As a result, the attitudes toward advance directives were accounted having 2.84 points, the functions of a family with 2.73 points, and the level of self-efficacy with 3.45 points. Participants who have higher family functions were found to have negative attitudes toward self-efficacy, as the relationship between two variables were in the negative correlation (r =-.324, p<.01). However, participants who have higher self-efficacy showed positive attitudes toward advanced directives as the two variables were in the positive correlation (r =.340, p<.01). This study will contribute to the settlement of the AD in Korea.
