This paper investigates both the spatial patterns of aging population and its formal regional structure in 2010. The results are as follows: first, aging index shows high values in remote mountainous and coastal regions while showing relatively low values in Capital Region and large provincial cities. Aging index has low negative correlation with such variables as population increasing rate, ratio of youth population, ratio of apartments, and ratio of newly built housing. However, aging index shows high positive correlation with variables including ratio of single unit house, ratio of aged peoples' house ownerships, ratio of welfare recipients, ratio of old housing, and number of public healthcare facilities. Secondly, four factors are identified from factor analysis including aging factor, welfare factor, economic vitality factor, and new town factor. The aging level of a region is negatively related to the strong level of those factors. Thirdly, cluster analysis results in four different types of formal regions including rural mountainous coastal type, rural non-capital region type, large metropolitan type, and provincial industrial city type.

Although everyone grows old, perception about the aging process and aging as measured physiologically vary widely. Perecptions of aging have psychologically influence on physical aging. This study was to examine the relationships between, self-concept, perception of aging, and physical aging in the elderly and to contribute to the theory development which may direct nursing intervention to promote well-being of the aged. Subjects were 70 women residents of a nursing home for the elderly in Seoul. Data collection was done from May 15 to June 15, 1988 using interview schedules and mechanical instruments. The instruments were selected items from the Health Self Concept Scale developed by Jacox and Stewart for self concept, and Secord and Jourad's Body Cathexis Scale and Osgood's Semantic Differential Scale for perception of aging. Physical aging was measured by mechanical instruments, inspection, questions, and palpation. The data were analysed for mean, 1-test, ANOVA, and Pearson Correlation Coefficient using an S.P.S.S computerized program. The results of the analysis were as follows. 1. The mean level of self concept for the subject group was 16.97(SD＝$\pm$6.17)in a range from 6-30. The mean level of perception of aging was 39.6. (SD＝$\pm$6.51) in a range from 13-65. The mean level of physical aging was 14.09(SD＝$\pm$2.05)in a range from 8-40. 2. Relationships among self - concept, perception of aging, and physical aging. 1) There was a positive relationship between self-concept and perception of aging(r＝0.4461, p＝0.000). 2) There was a negative relationship between physical aging and perception of aging(r＝-0.2975, p＝0.006). 3) There was a tendancy toward a negative relationship between physical aging and self -concept, but not a significant relationship (r＝-0.1033, p＝0.197). 3. 1) No general charcteristic variables were related to self concept. 2) The general characteristic variable related to the level of perception of aging was religion (t＝4. 17, p＝0.001). 3) The general characteristic variable related to the level of physical aging was age (F＝12.008, p＝0.000). There was a significant relationship between self - cencept and perception of aging, and between physical aging and perception of aging. Therefore nursing intervention should focus on promoting a positive perception of aging and strengthening self- concept during the physical aging process.

In the aged society, the quality of life of elders assessed by life satisfaction is important for successful aging. This study examined the impact of preparation for old age including social support and death anxiety on the life satisfaction of the elders. We analyzed the data which has obtained from 282 senior center users in Choong-chung-nam-do. A multiple hierarchical analysis showed the effect of preparation for old age, social support and death anxiety on the life satisfaction of the elders. In addition, we found a interaction effect preparation for old age and social support. These findings suggest the importance of social support and death anxiety as well as preparation for old age for successful aging.

All living organisms exhibit the characteristics of aging, such as skin wrinkle formation, muscle degeneration, cataracts, and hair graying as the number of aged cells increases over time. Senescence, which is known as a key cause of aging, is directly related to the aging of living organisms because cells are aged by external and internal factors and eventually cell proliferation is stopped. Senescence is caused by the gradual shortening of the telomere with cell division, and lifespan is determined by the length of the telomere. Recently, it has been found that the histone deacetylase, which can influence gene expression, is not only involved in yeast but also deeply involved in anti-aging mechanisms in both C. elegans and humans. It was also discovered that old cells play a decisive role in the aging phenomenon, and it has been reported that it is possible to promote the proliferation of young cells and delay aging by removing these senescent cells from the inside. Therefore, in order to develop potential anti-aging agents in the future, research should begin with an in-depth study of telomerase activators, sirtuin activators, and senolytics.

According as society looks graying trend gradually, more shaped system that can achieve measuring health-state of old people more harmoniously construction required in field of old people's welfare and medical treatment. Health-state is measured by two methods of contact and non-contact. The first, for example measurement of blood pressure or electrocardiogram, requires that measuring equipments are attached on human body but the second, for example X-Ray or MRI, is not. But both of methods are have some of defect, for example attaching equipments, needing of the special equipments or the necessary time, etc. Therefore desirable method of monitoring system must have minimum interrupt about daily life. This study suggest the system that can monitor the user, especially old people's outward aging and health-state by use the PAN TILTER and CCD camera.

As number of old and handicapped passengers is increasing in an aging society, it is becoming more and more important to provide safe and convenient subway interior design and direction. In this research, we study basic indispensable conditions for subway chair and propose a chair design direction for old and handicapped people considering their use. In this study, we elicit the rational result based on analysis of Seoul subway design direction. This study should be expanded into universal design for not only old people but also pregnant people and children. The chair for old people is needed to have side partitions and a safety bar for safe walking and to be made of soft materials which has some cushion.

In order to investigate the effects of Eucomiae Cortex extracts on the depression caused by aging, histochemistry and immunohistochemistry were performed on the hippocampus of aged rats and the following results were obtained. Experimental animals were divided into three groups as follows: 8 week old ICR male mice, Aging-elicited group (AE group) and Eucomiae Cortex treatment group (EC group) 50 week old male ICR mice were used. The control group and AE group did not take any treatment and did not restrict diets and negatives. In the EC group, 0.51g/kg of Eucomiae Cortex extract was dissolved in distilled water once a day for 6 months. The Eucomiae Cortex extract reduced pyramidal neuronal damage in C3 hippocampus and dentate gyrus, increased DJ-1, SHH positive responses in aged mouse hippocampus, and 8-OHdG positivity was reduced, ${\beta}$-endorphin positivity was reduced in aged mouse substantia nigra. Therefore, based on the above results, Eucomiae Cortex extract reduces damage of pyramidal neurons in the hippocampus caused by aging, inhibits neuronal cell death, induces proliferation and differentiation of stem cells in the hippocampus, reduces DNA damage-induced oxidative stress, so improves the reduction of hippocampus volume. It is also thought to improves depression due to aging through ${\beta}$-endorphin which enhances mood through the inhibition of pain.

'Long-life' which has been the perennial interest to human beings also carries the risk of multiple losses such as the death of the family members and friends, the loss of physical and cognitive functions. In that regards, living a long life to be the 'oldest-old' could mean not only a 'symbol of successful aging' but also a hardship and low quality of life at the same time. Therefore, the issue of the quality of life of the oldest old has been the subject of the much of the public and research concern in recent days. While there has been increased awareness about the importance of the subjective aspects of the quality of life and meanings attached to the extended life, most researches on the quality of life of the oldest-old have focused only on the objective conditions of the quality of life such as health, economic status and housing conditions. To overcome these limitations this study aims to explore the subject meaning of 'living a long life' in Korean society by investigating centenarians and their caregivers' interpretations of aging experiences. Qualitative data were gathered from the forty-nine Korean centenarians and their caregivers through in-depth interview. Each interview was tape-recorded and transcribed verbatim. Researchers read each transcript a number of times to get some emerging themes. Most striking result was the fact that most of the centenarians express the 'guilty feelings' and try to offer the 'excuses' about their long life. This results were quite contrary to the results of the studies, done in Japan and western countries like Sweden, United States and Germany, where most of the oldest-old express quite positive interpretations about their long-life and take pride in their longevity. Lack of social support, cohort characteristics of the Korean oldest-old and the cultural interpretations linking the death of children to the long life of older generation are given as possible factors to these unique findings of Korean study. The policy implications of the results are discussed.

Anti-skin aging agent could be have an inhibition effect of ROS production as well as fragmentation and change of collagen cross linkage in collagen molecule. For the monitoring of lipid peroxidation and collagen degradation, the skin of young and old rats were incised and observed 7 days. In the result, the wound closure was observed in the skin from 10 of 11 young rats and in 8 of 11 old rats. And the longer wound length but shorter wound closure, weaker collagen density and thicker epidermis were observed in old rats than in young rats. The level of hydroxyproline as a parameter of collagen synthesis and MDA as a parameter of lipid peroxidation was lower in old group than in young group. The cyst and lacuna between collagen bundle and fibroblast were observed in old rats in contrast to young rats. So that we propose that MDA and hydroxyproline could be used for monitoring of anti-skin aging agent.

Sleep is an essential component for health and the quality of life of individuals, and is affected by multiple factors. Thereby, sleep impairment is known to be frequent even in healthy subjects. The purpose of the study is to compare sleep patterns and related factors between healthy young and old adults and to identify aging effects upon sleep in a cross-sectional way. The survey questionnaire was developed by translation and modification of two well-known sleep questionnaires which were originally developed by Monroe(1967) and Ellis, et al. (1982). Discussion with experts and pilot study were completed to finalize the contents of the questionnaire that was used in this study. Results are as follows : 1. Sleep complaints were lower in older adults. 2. The most frequent variables that explain sleep satisfaction were feeling rested in the morning in the older adults and feeling rested and failing asleep within five minutes in the young adults. 3. Regarding sleep-disturbing factors, physical factors were more frequently reported in the older adults and environmental factors are reported more frequently in the young adults, and there was no difference related to the emotional factors between the two groups. 4. Young adults were practiced strategies for better sleep more often than the older adults, and they were mainly in-home activities just before sleep. 5. Sleep patterns which change with aging were as follows : going to bed and waking up earlier : not staying in the bed long after waking up ; getting harder to fall asleep ; frequent arousal after sleep onset ; getting harder to go back to sleep after arousal during night sleep. From the results of this study, it can be concluded that sleep and related factors of the young and the older adults are different. Also, sleep patterns change with aging and those changes seem to be negative for sleep in the elderly. Repeated studies are needed to establish more concrete information regarding sleep patterns. In addition, further research is needed to develop more reliable, valid, and feasible sleep measure tools, and to develop and evaluate nursing interventions.
