This study aims to examine how old people think about 'dignifiable aging'. For the study, the authors have tried to understand and analyze of old people's view on 'classy and gracious aging' through their life experiences. The study focuses on the questions of 'how the participants experience aging', 'how they understand well, classy and successful aging and 'how they explain their ideas of the aging, then analyzes their ideas as types of 'within cases' as well as 'inter cases'. Indepth interview has employed as main methodology of data collection with the analysis of concerned written documents such as on-line and off-line essays as secondary data. The collected data had been basically sorted and analyzed by sorting commonimity and differences. Then they have been classified into the thems that indicate meanings and forms of 'dignified aging': 'ageless mind', 'happiness determined by one's mind', 'responsibility on family', 'desire for learning and social activities'. These meaning-units are added up to the main meaning of '(fullfilled) satisfaction through life-values' mediated by 'acceptance and acknowledgement', 'efforts', 'others' gaze', 'dreams and hopes', '(fullfilled) Satisfaction through life-values' can be achieved by 'sharing with others'. An interesting fact is that the meaning-units can be devided into two groups: 'the real life is the ideal life' which explains the actualization of the ideal in the daily life and 'life, conflict, the ideal' in which the real and the ideal are parellel with constant conflicts. In the conclusion, some implications and suggestions derived from the analysis are described from the v iew of social welfare.

Traffic accident by aging drivers is expected to be on the rise rapidly as the number of aging drivers is rising along with the aging trend being progressed. In this study, traffic accident features depending on the classification of aging population and non aging one was evaluated. As a result of this evaluation, effect factors influencing over the aging population was found to be expressed differently from that of the non aging one. Odds ratio between the aging population and non aging one was evaluated through logit model and a model with potential accident probability of the aged drivers was developed. Accident risk of the aged drivers under the condition of curved road, cutting section and moistured road was revealed to be higher than that of the non aging population.

This study was performed to investigate the effects of n-3 fatty acids on renal function in male Sprague-Dawley rats of different ages 5-, 15- and 19-months old. The rats were fed a 20%(w/w) lipid diet containing 10% fish oil, compared with control animals fed a 20% lipid diet without fish oil for 4 weeks. The results were as follows: kidney weights were significantly higher in fish oil-fed rats compared to control rats. Plasma levels of total lipid, total cholesterol, and triglyceride markedly increased, with aging and LDL-cholesterol showing a significantly lower level in fish oil-fed rats than control rats. The urinary protein and glomerular filtration rate (GFR) increased with aging. GFR was higher in fish oil-fed rats. However, urinary protein was the same in the two groups. Renal medulla thromboxane B$_2$(TXB$_2$)tended to be lower in fish oil-fed 19-month-old rats. Urinary TXB$_2$and PGE$_2$were found to be higher proteinuria. Light microscopic examination showed interstitial inflammation, tubular atrophy, interstitial fibrosis and glomerular mesangium increase. Although glomerular sclerosis increased with aging, fish oil in the diet had no effect on histological changes. In conclusion, plasma lipid, urinary protein excretion and renal histological change showed a significant increase with aging. The reduction of TXB$_2$in the medulla and increase of GFR caused by fish oil indicated n-3 fatty acid could affect renal function in line with the hypolipidemic effect.

The present study was designed to investigate aging-related effects on the activities of xenobiotic metabolizing enzymes of rat liver by dietary supplementation of Korean red ginseng water-extract. Rat did not show any discernible signs of the rejection symptoms, and blood GOT and GPT levels were not influenced by ginseng water extracts, Cytochrome 450 levels and NADPH cytochrome P45O reductase, p-450 dependent ethoxycoumarin O-deethylase, and benzphetamine N-demethylase activities were decreased with aging, however, these phase I system enzymes activities in the ginseng group of24 months were well maintained compared with normal group. But, Levels of cytochrome bs and NADH-cytochrome b$_5$ reductase activities were also decreased with aging and were not found a clear difference between two groups. Glutathione-s-transferase activity, phase II enzyme system, in liver cytosols was also decreased in old ages, but the degree of decrease was higher in normal group than in giuseng supplemented group. These results indicate that long-term supplementation of red ginseng water extracts from weaning to 24 months do not show any side effects to rats, and retard age-related deteriorations of xenobiotic metabolizing enzymes activities in old ages.

People hope to live a healthy and happy life achieving satisfaction by striking a good work-life balance. Therefore, there is a growing interest in well-aging which means living happily to a healthy old age without worry. This study identified important factors related to well-aging by analyzing news articles published in Korea. Using Python-based web crawling, 1,199 articles were collected on the news service of portal site Daum till November 2020, and 374 articles were selected which matched the subject of the study. The frequency analysis results of text mining showed keywords such as 'elderly', 'health', 'skin', 'well-aging', 'product', 'person', 'aging', 'female', 'domestic' and 'retirement' as important keywords. Besides, a social network analysis with 45 important keywords revealed strong connections in the order of 'skin-wrinkle', 'skin-aging' and 'old-health'. The result of the CONCOR analysis showed that 45 main keywords were composed of eight clusters of 'life and happiness', 'disease and death', 'nutrition and exercise', 'healing', 'health', and 'elderly services'.

This study was performed to see effects of whole grape, grape pomace or grape juice intakes on lipid metabolism during aging in old Sprague-Dawely male rats. One hundred twenty rats of 13 months old Sprague-Dawely were blocked into eight groups according to body weight and raised for 3, 5 or 7 months with diets containing 2% (w/w) dried powders of three different pars of grape and 0.02% (w/w) CdCl₂. Body weights of Cd groups were lower than Cd free groups. Kidney and spleen weights were incre ased with age, and EEP weights of Cd groups were lower than those of Cd free groups. Total lipid, triglyceride and total cholesterol concentration in plasma increased with age. Whole grape, grape pomace or grape juice intake lowered plasma total lipid triglyceride and total cholesterol concentrations, and especially grape pomace lowered them markedly. Whole grape, grape pomace or grape juice intake decreased liver total lipid, triglyceride and total cholesterol concentrations and increased fecal lipid excretion. Grape diets decreased and Cd administration increased TBARS concentration in LDL fraction. In conclusion, grape diets were effective in decreasing lipid levels of liver and plasma, TBARS in LDL, and in increasing HDL cholesterol. The grape pomace was most effective among three grape parts. It is plausible that grape might be recommended for the treatment or prevention of cardiovascular disease and delaying aging. (Korean J Nutrition 35 (7): 713∼728, 2002)

This paper investigates both the changing spatial patterns of aging population during 1985 to 2010 and their interrelationship with the residential features of elderly households in 2010. The aging level of a region is classified into three different ones such as aging region (7~14%), aged region (14~20%) and super-aged region (over 20%). Residential features of elderly households are examined by such variables as housing type, housing ownership, and house age. Aging process has started from peripheral regions distanced away from Seoul. There are strong tendency that aging households reside in single unit house owned by oneself over 20 years-old aged houses, which shows more strong patterns toward peripheral regions in SMR.

Objective: The length of anterior-posterior commissure (AC-PC) in racial groups, age, gender of patients with deep brain stimulation (DBS) and pallidotomy were investigated. Methods: From January 1996 to December 2003, 211 patients were treated with DBS and pallidotomy. There were 160 (76%) Caucasians, 35 (17%) Hispanics, 12 (5%) Asians and 4 Blacks (2%). There were 88 males and 52 females in DBS-surgery group and 44 males, 27 females in pallidotomy group. Mean age was 58 year-old. There were 19 males and 19 females and mean age was 54.7 years in the control group. Measurements were made on MRI and @Target software. Results: The average AC-PC distance was 24.89 mm (range 32 to 19), which increased with aging until 75 years old in Caucasian and also increased with aging in Hispanic, but the AC-PC distance peaked at 45 years old in Hispanic. The order of AC-PC distance were $24.6{\pm}2$ mm in Caucasian, $24.6{\pm}2.24$ mm in Asian, 24.53 mm in Black, $23.6{\pm}1.98$ mm in Hispanic. The average AC-PC distance in all groups was 24.22 mm in female who was mean age of 56.35, 25.28 mm in male who was mean age of 60.19 and $24.5{\pm}2$ mm in control group that was excluded because of the difference of thickness of slice. According to multiple regression analysis, the AC-PC distance was significantly correlated with age, race, and gender. Conclusion: The AC-PC distance is significantly correlated with age, gender, and race. The atlas of functional stereotaxis would be depended on the Variation of indivisual brain that can influenced by aging, gender, and race.

As the life-expectancy is ever-increasing, and the proportion of the elderly population is growing steadily in every society of the world, it is ever more important to establish what factors allow certain elderly people to age successfully and remain relatively independent while others grow old less successfully and require extensive intervention. However, there is no consensus yet as to what successful aging means. Researchers have defined successful aging in a variety of ways. This study attempted to define the concept of successful aging and to clarify some dimensions of it through literature review. Previous approaches of studying successful aging and related themes were examined. Early perspectives including activity, disengagement, and continuity theories, Selective Optimization with Compensation (SOC) model by Baltes and Baltes, three different conceptions of successful aging, that is, psychological well-being, physical health, and wisdom, and MacArthur research on successful aging have been reviewed for this study. The definition derived from the review is: Keeping up continuous developmental processes to achieve wisdom or ego-integrity, without suffering any major disabilities in either physical or mental functioning, while maintaining psychological well-being and employing SOC strategies, and participating in positive relationships with significant others. The dimensions of successful aging are 1) personal resources, including physical health, cognitive competences, self esteem, and social support 2) adaptation process of SOC, and 3) psychological aspects, including psychological well-being and wisdom.

Recently, there shows a trend in Korea that the rate of the population entering into aging is the most rapidly increasing among the OECD countries. Consequently, This study, therefore, aims at analyzing the forms of portfolio establishment by group, the factors affecting the old age preparation, and the presence of middle-aged households' preparation for the old ages in order to forestall social problems like the poverty ration of elderly that have been caused by the rapidly aging society. The result shows that the portfolio for the old age preparation can be expanded if a combination product of finance and real estate is developed as a means of old age preparation. Upon the results of the study above, it can be seen that the old age preparations differ according to not only the demographic elements, but also the extent to how much resources one holds. Especially, the various factors affecting the holding resources vary householder by household depending on whether they prepare for the old ages or not.
