This study examines the structure of intergenerational relationship and its effects on old-age security of the Korean society. Of interest is the effects of the middle aged's attitudes on old parents'security on their intergenerational exchange relationship and on their own old-age security as well. This study also attempts to test the applicability of the social exchange perspective to the study of intergenerational support relationship in Korea The social exchange perspective considers intergenerational relationship as an exchange of aids and rewards between generations. However due to strong norm of filial duty and inadequate welfare system, supporting old parents is regarded as younger generation's duty in Korea This study utilizes a survey data conducted by Kim et al.(2000). Major findings can be summarized as follows. First, the middle aged who gives one-sided supports to their parents tends to have the traditional attitude on old parents' security. It implies that intergenerational support relationship in Korea is not consistent with the explanations from the social exchange perspective. This study suggests a 'chained reward system'as an altermative explaining the intergenerational relationship. Second, an absolute majority of the middle aged tend to think that they are responsible for their own old-age security regardless of the pattern of intergenerational support relationship and attitudes on old parents' security. It implies that the middle aged in Korea holds the status of 'marginal men' who supports their parents but can't take the similar supports from their children.

The activities of the antioxidative enzymes in the roots of Codonopsis lanceolata have been compared depending on the cultivated environments - wildness, cultivate paddy fields and cultivate dry fields - and the parts of the root. In the Codonopsis lanceolata raised in cultivate paddy fields, the activity of SOD was higher in 2 yrs old than 1 yr old, but the activity in 1 yr old was higher than in 2 yrs old for the plants raised in the cultivate dry fields. The specific activity of SOD in wildness plants 86.069unit/mg protein was the highest among plants studied. The tissue distribution of the SOD activity showed differences depending on the enviroment. The highest activity of SOD was shown in the upper part of the root for the cultivate paddy fields, the loewr parts for the cultivate dry fields and middle parts for the wildness. The specific activity of POD was increased with ages of the plants, and that in the wildness was the highest 68 unit/mg protein among the plants studied. The activity of POD in the parts of the roots was shown as middle>lower>upper. The activity of POD in the middle part of the root, rasied in Soebick province was 85 unit/mg protein. The specific activity of CAT was decreased with ages of the plants. The activities of wildness and cultivate paddy fields was similar, but that in cultivate dry fields was lower than others. The tissue distribution in the parts of the roots was upper>lower>middle. The activity of CAT middle part of rasied in the Sebuck area was 5.359 unit/mg protein. The activities antioxidative in the cells cultured in MSID(Murashige and Skoog +2.4-D 1mg/$\iota$) was followings: 1564 for CAT. 30 for POD and 22200 unit/mg protein for SOD. These figures were lower than that in in vivo.

In recent years, the average life span of people in advanced countries has increased. Conwequently, the number of middle-aged and old workers who have the will to work has increased. On the other hand, the declining birth rate has decreased the number of young workers. However, because many enterprises in advanced countries have extended their mandatory retirement age from 55 to 60 years, labor accidents involving aged workers are on the increase. As a result, the need for a method to evaluate the work skills of middle-age and old workers has become urgent. To explore one such method, this study investigated the relationship between aging and manual dexterity. Dexterity was found to deteriorate with age, but with large variability from individual to individual. The parameters of dexterity used in this experiment were found to be reliable.

The purpose of this study is to explore the effects of the middle aged's perception of successful aging on their preparations for the old age. We used data from 350 participants, aged 35-64 in Seoul-Gyonggi region. The hierachial regression analysis estimated the relation between the middle aged's perception on successful aging and their preparations for the old age. The findings indicate that the middle aged's level of preparations for the old age was slightly higher than average. The level of their emotional preparation appeared highest and the level of economical preparation showed lowest. The perception of successful aging indicated relatively high, and especially the level of comfortable everyday life showed highest. The results also showed that personal characteristics influencing on preparations for the old age were sex, age, marriage status, religion, occupation, monthly income, health condition, level of plan for the old age, and social activities frequency, and demonstrated that the perception of successful aging effected on preparations for the old age positively.

Adults in their middle age are being held back by their roles through economic activities, but their rapid retirement and job sharing are adding to their anxiety. Also, it is very important to establish welfare policies for the elderly in the future because it can predict the economic situation in the old age through the economic activities of middle-aged adults. My study analyzed the 6th data of Kreis of the National Pension Research Institute's. The number of people studied is 2,552 employed people aged 40 or over 64 across the country. According to the analysis, there were more men than women. There were many high school graduates and 50s. There were many people who had spouses and who lived in the province. Wage workers represented 53.1% of the total. The lower the age, the higher the level of education, the higher the number of wage earners. Only 29% of standard workers and 30.8% of regular workers were employed. There were many economically unstable middle-aged adults. Economic instability in the middle age requires social attention because it can lead to poverty in old age. Therefore, measures should be taken to ensure stable jobs for middle-aged adults, whose spending increases more than their income.

This study divided school age by considering a change in the stage of body growth by age in elementary schoolgirls with the use of body scan data, and considered by comparing body size characteristics by school age. Elementary schoolgirls' body shape cannot be divided clearly. However, ages 7-10 were bound into the same group for the majority of girth, width, and thickness items. 7-8 years old, 9-10 years old, and 11-12 years old were bound into the same group in most items except ages 9 and 10 for the height item. Thus, significant difference was indicated between groups. Accordingly, this study divided the school age into three periods such as early stage(ages 7-8), middle stage(ages 9-10), and late stage(ages 11-12) in consideration of the stages for elementary schoolgirls' body-shape growth. As a result of analyzing body size according to division of school age, the higher school age leads to continuous growth. The notable growth was indicated especially in the middle stage and late stage. Examining centering on typical items related to the clothing construction, there was notable increase in waist thickness and hip thickness between early and middle stages and in height, weight, breast girth, waist circumference, back length, breast width, and waist width between middle and late stages. On the other hand, hip circumference, hip width, breast thickness, and length between shoulder edges were indicated to grow relatively and evenly among early, middle, and late stages. The lateral form was shown a clear difference in the forms of early, middle, and late stages in height and length of the whole body shape and in side thickness. The early and middle stages belong to body shape that abdomen is projected to be curved. The late stage showed right body shape which is straight and stable form in posture.

This research intends to find out the impact of housing wealth of home-owning pre-retirees and older adults consisting of young-old, middle-old and old-old groups on their household consumption. In doing so, this research analyzes 2,350 home-owning households by utilizing the 17th Korean Labour and Income Panel Study (KLIPS). The results show that housing wealth has a statistically significant effect on non-durable consumption of the pre-retirees, and young-old and middle-old groups of older adults, and housing wealth has a much stronger effect on household expenditure than does financial wealth or real estate. It's found that the consumption elasticity is particularly greater for female-headed households living in SMA, residing in apartments, holding a lower debt-to-asset ratio and being a pensioner. The empirical findings imply that the old-old group of older adults is unlikely to actively tap into their housing windfalls since housing asset becomes the last to dispose in the course of an individual's life. As housing wealth effects are especially strong when liquidity constraints faced by older adults are removed, it's of significance to substantially reduce household debt before retirement in order to constantly maintain an adequate level of household consumption or to promptly prepare for future contingencies.
