Older people have increased interest and involvement in controlling their aging body through physical exercise and dieting. This study examined the relationship between body image and the participation of older people in exercise and dieting. Two measures of body image (appearance attitude and appearance orientation) were used to study their relationships to participation in exercise and dieting among older people. Data were collected via a mail survey of older married couples residing in three U.S. metropolitan areas of Florida. A total of 94 couples who were 60 years older participated in this study. Multiple regression was run separately for men and women. The results indicated that for both men and women, appearance attitude was inversely related to dieting and positively related with exercise (even though the relationship with exercise was weak for men). Appearance orientation was not significantly related to exercise or dieting for both men and women. A new scale development on body image for an aging population was suggested. Various activities performed by aging people to manage their aging body and appearance need to be studied as related to physical and psychological well-being that includes body image.

Many efforts to understand the deterioration processes of the beeswax-treated volume of "The Annals of Joseon Dynasty" have been made. However, most previous studies have focused on individual sample sheet of the beeswax-treated paper but not book volume format. In this study, humid cycling accelerated aging for duplicated beeswax-treated book volume and Hanji book volume were carried out to examine differences in the deterioration of different parts of each volume as well as between the two book volumes during the aging. As results, it is found that the deterioration rate for the beeswax-treated volume is higher than that for the Hanji book volume. Different parts in each volume show different magnitude of deterioration. In particular, outer sides in both beeswax-treated and Hanji book volumes, which are directly exposed to the air, are deteriorated more seriously than inner sides. It is also observed that inner sides are considerably deteriorated during the aging, implying that inner deterioration may have different mechanisms from outer deterioration.

The purpose of this study was to show the occurrences of musculoskeletal disease in aging society and basic information on developments of a systematic prevention program and proposed management measures needed to prevent the disease. The Korea Occupational Safety & Health Agency has analyzed cases of industrial accidents that cause musculoskeletal disease, from 1998 to 2007. They found 30,439 people suffering from the disease during those ten years. This information is from the Ministry of Labor's industrial accident analysis and the industrial accident survey from the Korea Occupational Safety & Health Agency. The data was analyzed by age and industrial classification. In Korea, according to the studies on aging society, the occurrence of musculoskeletal disease in elderly employee's have increased, so prevention programs are needed. Psychological, mental and cognitive programs are needed, as well as other prevention programs to ensure health in old age. In this study, we were able to see the state of musculoskeletal disease in aging society and the countermeasures to prevent the disease, such as a universal design, guarantees, and recuperation services. Later, we found that studying the various elderly patients would be of great help to us.

The Blu-ray Disc Recordable(BD-R) is one of strong candidates for archival application among optical media formats, because of its large capability. However, the well-defined accelerated aging test conditions and evaluation criteria have not yet been fully confirmed for BD-R. In this study, the data stability and degradation aspect of BD-R were analyzed by the random-symbol error rate(R-SER) measurement after the accelerated aging test. And a reasonable test condition of accelerated aging for BD-R and the appropriate evaluation criterion using R-SER measurement were discussed.

The strain aging behavior of a low carbon dual phase steel was examined in two conditions: representing room temperature strain aging (100 ℃ × 1 hr after 7.5 % prestrain) and bake hardening process (170 ℃ × 20 min after 2 % prestrain), basing on carbon effective diffusion and dislocation distribution. The first principle calculations revealed that (Mn or Cr)-vacancy-C complexes exhibit the strongest attractive interaction compared to other complexes, therefore, act as strong trapping sites for carbon. For room temperature strain aging condition, the carbon effective diffusion distance is smaller than the dislocation distance in the high dislocation density region near ferrite/martensite interfaces as well as ferrite interior considering the carbon trapping effect of the (Mn or Cr)-vacancy-C complexes, implying ineffective Cottrell atmosphere formation. Under bake hardening condition, the carbon effective diffusion distance is larger compared to the dislocation distance in both regions. Therefore, formation of the Cottrell atmosphere is relatively easy resulting in to a relatively large increase in yield strength under bake hardening condition.

In the last decades patient's suffering with Parkinson's disease is increasing at a rapid rate and as per prediction it will grow more rapidly as old age population is increasing at a rapid rate through out the world. As the performance of wearable sensor based approach reached to a new height as well as powerful machine learning technique provides more accurate result these combination has been widely used for assessment of various neurological diseases. ON state is the state where the effect of medicine is present and OFF state the effect of medicine is reduced or not present at all. Classification of ON/OFF state for the Parkinson's disease is important because the patients could injure them self due to freezing of gait and gait related problems in the OFF state. in this paper wearable sensor based approach has been used to collect the data in ON and OFF state and machine learning techniques are used to automate the classification based on the gait pattern. Supervised machine learning techniques able to provide 97.6% accuracy while classifying the ON/OFF state.

This study aims to develop the Korean types of continuing care retirement communities (CCRCs). CCRC is well evaluated as a residence that applies aging-in place concept, which is ideal for senior housing. Recently, in USA the CCRCs in which the increasing seniors' population and older households are guaranteed to get continuous protection without moving regardless of their deteriorating health are increasing. In Korea, CCRCs have emerged but not well developed in status quo. We conducted case study using three facilities located at Seoul and its suburbs in Korea to compare five categories such as application of 'aging in place' concept, location, architectural features, services or programs, and management. This study is expected to be used basic materials for CCRCs' complex and architectural planning, management strategies, and services or programs.

Elderly entrepreneurship is becoming increasingly important as a response to the impact of the aging population and the resulting demand on government support systems, as well as a means of ensuring long-term economic and social development. The purpose of this study is to investigate the elderly's entrepreneurial intentions in the hotel and tourism sector in Ma'anshan City, Eastern China. The researcher used an online survey of older people aged 50 to 64 in a tourism destination that is approaching an aging society stage to see if the Theory of Planned Behavior can explain the entrepreneurial ambitions of the elderly in the hospitality and tourism industry. There were 391 questionnaires gathered in all, 367 of which were valid. The data was analyzed using descriptive statistics and regression analysis. The study reveals that personal attitudes toward entrepreneurial behavior and perceived behavior control are highly influenced by societal norms. It also shows that personal attitude and perceived behavior control are antecedents of the elderly's entrepreneurial intent in this particular industry. This research adds to the research on geriatric entrepreneurship in hospitality and tourism, as well as human resource development for seniors in China, helping to alleviate the country's aging demographic concerns.

Before considering health promotion programs carried out in Japan, I would like to explain a summary of today's health conditions of Japan for a while. Current major concern in public health world as well as political or economic world is an aging society. To say more precisely, it would be an aging society with relatively small children's population. Estimated total population is 126,166,000 in 1997. Among these, almost 10％ population loves in Tokyo Metropolitan Area. (omitted)
