According to the 2005 Korean census, the 65 and over population now exceeds 9.5% of the total population and is growing rapidly. Meeting elderly environment and care needs of this rapidly growing segment of the population becomes a major challenge for public policies and planners. Since great deal amount of elderly will reside in their houses, aging in place concept becomes important. For the success of aging in place, the quality of individual house unit, community support systems, and quality of senior center of the community are crucial. Since elderly environments and facilities serve not only medical and/or care programs but also social activity program in aging society, senior centers need to promote social activities and other care programs. The purpose of this study is to analyze characteristics of environmental affordance of a well received senior center in Tokyo, Japan. In order to analyze the characteristics, Murtha & Lee user benefit criteria and Lawton's environmental affordance approaches were used. As results, design characteristics and interior elements which provide environmental affordance were enumerated by type of space. Based on needs and user benefit criteria, those features were analyzed. This study shows design characteristics, elements, and attributes which are well received and utilized by elderly users.

Aging is the progressive accumulation of changes with time associated with responsible for the ever-increasing susceptibility to disease and death which accompanies advancing age. Lipid peroxides easily produced in the membrane system by the chain reaction of free radicals which occurred from various environmental factors. The amount of lipid peroxides produced in biological system increased with aging process, and lipid peroxidation damages involved in aging process and pathological disorders. Although lipid peroxides have such deleterious effects on the organisms, there are numerous substances and mechanisms which prevent the reaction of peroxide formation and protect the subject from its toxicity. This review provides an overview of how does lipid peroxidation of unsaturated lipids take place by free radical, and what is the intervention of lipid peroxides in pathogenesis of some human diseases, and also how does food restriction influences the aging process and various pathological disorders. The major focus of this paper is to review the evidence indicating that food restriction retards the aging process, and possible mechanisms of its actions. Therefore, it discussed the effects of age and food restriction on life-span, membrane yield, lipid peroxidation, fatty acid composition and peroxidizability, cholesterol and triglyceride levels, prostaglasndin and thromboxane synthesis, which may be concerned with blood flow, membrane fluidity, homeostasis and glomerular filtration rate in living body.

Objective:This study aims to devise industrial injury prevention measures by analyzing industrial injury characteristics including the status of industrial injuries, source of industrial injury and accident type in order to prevent aging workers' industrial injuries that account for more than half in the workplaces in agriculture. Background: Continuous migration from farm to city takes place among young people in rural areas in Korea, a traditionally agricultural country due to rapid industrialization and economic development. The aging rate in rural areas in 2013 was 37.3%, about three times higher than the total aging rate of 12.2% in Korea. According to industrial injury statistics of the Ministry of Employment and Labor, the number of industrial injuries in agriculture shows an uptrend and the industrial injuries of aging workers account for more than 50% each year. Method: Of the 2,970 industrial injury cases occurred in the workplaces in agriculture for five years during 2008 and 2012 offered by a national agency related to health and safety, this study analyzed 1,767 industrial injury cases of aging workers. Results: As a result of an analysis on aging workers' industrial injuries by company size in agriculture, 89.8% of the total number of industrial injuries were analyzed to occur in small scale company. According to aging workers' industrial injuries by source of industrial injury and accident type, the outdoor floor and a fall were analyzed to be the highest at 16.5% and 26.1%, respectively. Conclusion: This study analyzed aging workers' industrial injuries by company size, age, job duration, accident severity, gender, nationality, the source of industrial injury and accident type in order to identify industrial injury characteristics in agriculture. Application: The identification of industrial injury characteristics of aging workers in agriculture is judged to be helpful to devising effective measures to prevent industrial injuries.

The aging of farm households has caused serious problems such as productivity slowdown and aggravated income polarization in South Korea. Urban-to-rural migration has been recently suggested as a measure to attenuate the aging of rural population and other related problems. The inflow of migrants for farming can have a substantial effect on agriculture and rural communities while the natural adjustment of rural population caused by birth and death is slow. This paper forecasts population distribution of different provinces using the Origin-Destination (OD) analysis, taking into account both the size and directions of migration. In the analysis, nodes where the migration takes place are divided by the industrial sectors (agriculture and non-agriculture), regions, and ages. The results of a ten-year forecast shows that the aging of total population in most provinces will be intensified, but the portion of people over sixty will decrease in the agricultural sector. This finding implies that migration into rural areas, when occurring by a large extent, can mitigate the aging process and attendant problems.

Aging populations and the increasing mental health issues among them have set a new challenge for the international community, governments, and people. Given this, society's role is very important, and involving the local community in resolving the problems can play a pivotal role. The current study presented the systematic review of the financing mechanism and cost-effectiveness of the "social prescribing" (SP) project in the United Kingdom and how SP can be adapted for other settings. The data showed comparatively low running costs and the overall effectiveness of SP projects. The running cost of SP projects varied between £54,525 and £1.1 million. The cost-effectiveness of the projects reported as 12% and the return of investment was about 50% depending on the type of analysis and the activities implemented. This type of intervention can be one of the options that support solving the issues of aging populations and their accompanying mental disorders.

Housing selections of the elderly depends on various changing factors as they get old. Among those factors, housing satisfaction might be one of the most predictable and crucial factor. This study is focused on the casual effect of housing satisfaction on the elderly's likelihood of selection among three alternatives of housing type. The sample was selected from 349 elderly aged above 65 who were living in Jeonju area, and was analyzed from multiple regressions and casual analysis. The results could be summarized as follows; First, the elderly preferred 'their own house living at present (aging in place)' among three housing type. Second, factors that influenced on housing satisfaction of the elderly were condition of health, economic status, living with spouse or not, level of social activities, and family supports. Third, the elderly who were male, without spouse living in single-family houses, in better health condition and with lower educational level were having more likelihood of selection of present housing. The elderly who were having more likelihood to select reverse mortgage payment were male, with spouse, living in apartment houses, the older, in worse health conditions and economic status. And the elderly who were male, with spouse, living in apartment houses, and in worse health conditions were having more likelihood to select national rental housing.

Technology has had a tremendous impact on our daily lives. Recently, technology and its impact on aging has become an expanding field of inquiry. A major reason for this interest is that the use of technology can help older people who experience deteriorating health to live independently. In this paper we give a brief review of the in-home monitoring technologies for the elderly. In the pilot study, we analyze the possibility of employing the data generated by a continuous, unobtrusive nursing home monitoring system for predicting elevated(abnormal)pulse pressure(PP) in elderly(PP=systolic blood pressure-diastolic blood pressure). Our sensor data capture external information(behavioral) about the resident that is subsequently reflected in the predicted PP. By continuously predicting the possibility of elevated pulse pressure we may alert the nursing staff when some predefined threshold is exceeded. This approach may provide additional blood pressure monitoring for the elderly persons susceptible to blood pressure variations during the time between two nursing visits. We conducted a retrospective pilot study on two residents of the TigerPlace aging in place facility with age over 70, that had blood pressure measured between 100 and 300 times during a period of two years. The pilot study suggested that abnormal pulse pressure can be reasonably well estimated (an area under ROC curve of about 0.75) using apartment bed and motion sensors.
