The aging population has been increasing in Korea so that it is difficult for people to understand the change of the future society. This study aimed to analyze the characteristics of preliminary retiree's alternative housing preference by providing an accurate information about residential current issues and the seriousness brought by the aging society. It explained the visual information about the aspect of the residential change due to the aging society to 104 preliminary retirees who live in the apartment in Seoul. It surveyed the characteristics of the alternative housing preference following 4 situations of the Old age type(couple/healthy, couple/ill, single/healthy, single/ill). It analyzed the difference of housing preference before and after providing information. The results are as follows: First, a previous apartment is not enough to prepare the aging society and UIBS(unit insertion building system) for the elderly was expected to be a great help to the frail after 2026. Second, the preference of UIBS was increased after providing information of the aging society. Third, in the case of the illness, a big city with medical facilities was preferred not to move in the suburb. Fourth, after providing information, a small size of apartment was preferred but the preferred change of housing ownership was not founded. Last, there was considerable difference before and after providing information under 4 situation of Old age type. These results showed the feasibility of coping with more accurate future society only if a survey should be taken with providing sufficient information about the aging society.

This study explored the tendencies of public perception and countermeasures on an aging society by the content analysis of Korea's four major daily newspapers since 2000. Results showed distinguishing growth of the public interest on an aging society. Articles were categorized into five domains - demographic structure, family and individual domain, health domain, economic and financial domain, and social domain. Economic and financial aspects occupied the highest frequency in the total number of articles. The analysis of public perception revealed both negative and positive perspectives on an aging society. In addition, the analysis of the newspaper articles identified particular phenomenon of Korean aging society as distinct rapid aging population, declining fertility rates caused by higher educational expenses, national security problems. Consequently, when we prepare for the alternatives of the aging society, we should pay attention to more various aspects of society based on the understanding of practical problems and needs. Furthermore, researches and discussions focusing on a particular phenomenon of Korea would be required.

The average life span is expanded due to the development of modem society, material and cultural life and increasing level of public health. This means that the aging society is rapidly progressing. Geniatric diseases also have increased due to increasing of the aged population. Along with an increase of the aged patient, the anti-aging, prevention of geniatric disease and quality of life is tending high on social concern and medical issues. Many reports showed the evidence to the positive anti-aging effect of Oriental medicine. Qigong therapy, a kind of Oriental medicine, has been used to prevent aging and life prolongation with positive effect for many thousand years. Therefore, qigong practice is popular and common to middle age and old age in China.

It has become ever harder to design reliable circuits with each nanometer technology node under normal operation conditions, a transistor device can be affected by various aging effects resulting in performance degradation and eventually design failure. The reliability (aging) effect has traditionally been the area of process engineers. However, in the future, even the smallest of variations can slow down a transistor's switching speed, and an aging device may not perform adequately at a very low voltage. Because of such dilemmas, the transistor aging is emerging as a circuit designer's problem. Therefore, in this paper, the impact of aging effects on the delay and power dissipation of digital circuits by using nanomneter MOSFET power gating structure has been analyzed.. Based on this analyzed aging models, a reliable digital circuits can be designed.

Aging is characterized by a functional decline in most physiological processes, including alterations in cellular metabolism and defense mechanisms. Increasing evidence suggests that caloric restriction extends longevity and retards age-related diseases at least in part by reducing metabolic rate and oxidative stress in a variety of species, including yeast, worms, flies, and mice. Moreover, recent studies in invertebrates - worms and flies, highlight the intricate interrelation between reproductive longevity and somatic aging (known as disposable soma theory of aging), which appears to be conserved in vertebrates. This review is specifically focused on how the reproductive system modulates somatic aging and vice versa in genetic model systems. Since many signaling pathways governing the aging process are evolutionarily conserved, similar mechanisms may be involved in controlling soma and reproductive aging in vertebrates.

Aging is characterized by a gradual decline in biological functions, leading to the increased probability of diseases and deaths in organisms. Previous studies have identified biological factors that modulate aging and lifespan, including non-coding RNAs (ncRNAs). Here, we review the relationship between aging and tRNA-derived small RNAs (tsRNAs), ncRNAs that are generated from the cleavage of tRNAs. We describe age-dependent changes in tsRNA levels and their functions in age-related diseases, such as cancer and neurodegenerative diseases. We also discuss the association of tsRNAs with aging-regulating processes, including mitochondrial respiration and reduced mRNA translation. We cover recent findings regarding the potential roles of tsRNAs in cellular senescence, a major cause of organismal aging. Overall, our review will provide useful information for understanding the roles of tsRNAs in aging and age-associated diseases.

The objective of the study was to cast a frame for the integrating concept of successful aging together with for understanding both elderly problems and aging, which was one of the major issues in aging society. For this, the author reviewed the meaning of aging and also made a general survey of both affirmative change such as growth and development and negative change with regard to aging. Particularly, it was observed that wisdom is a key factor for successful aging. The existing theory of successful aging and major study results were reviewed. As a result, the author proposed an integrated conceptualization of successful aging under the general discussion of the limits of existing theory and also explained the characteristics and implications of an integrated conceptualization of successful aging in line with the discussion on the definition of the integrated concept of successful aging.

Purpose: The purpose of this study was to identify aging anxiety and influencing factors of middle-aged adults. Methods: Descriptive correlation design was used. Three hundred and three middle-aged adults participated in the study and completed the questionnaires in the period from September 11 to October 15 of 2011. The data was analyzed using independent t-test, one-way ANOVA, Scheff$\acute{e}$ test, Pearson correlation coefficients, and hierarchial multiple regression analysis. Results: Aging anxiety of middle-aged adults was higher than a moderate level. Socio-demographic variables such as age, religion, education, economic level, perceived health status and experience of living with older adults influenced significantly on aging anxiety. In contrast, general self-efficacy, aging knowledge and attitude toward older adults were negatively correlated with aging anxiety. Hierarchial multiple regression analysis incorporating these variables showed an explanation rate of aging anxiety at 21%. And religion, perceived health status, attitude toward older adults, and general self-efficacy were statistically significant among variables that influence on aging anxiety. Conclusion: The findings of this study suggest that senior preparation programs that can enhance self-efficacy, induce positive attitude on older adults and promote health should be implemented to reduce aging anxiety of middle-aged adults.

To evaluate the aging of a rubber pad in power window switch which is the part of a vehicle, the accelerated thermal aging test of rubber pad material is performed. Finite element analysis was performed using the nonlinear material constants of the rubber pad to calculate the operating force, and the Arrhenius relationship was derived from the aging temperature and time. The aging test was performed at 150, 180, 210, or 240 ℃ for 1 to 60 days. When the operating force of the rubber pad is changed by 10% from the initial value, the service life is expected to be 113 years, which is much longer than the life of the vehicle. This indicates that the aging life of the rubber pad is sufficiently safe and the operating force of the rubber pad during the life of the vehicle (20 years) was decreased by approximately 8.4%. By examining the correlation between the shear elastic modulus and operating force calculated from finite element analysis under each aging test condition, the changes in the operating force of the rubber pad and the shear elastic modulus showed good linear relationship. The aging life could be predicted by the change in shear elastic modulus and a process for predicting the aging life of automotive power window switch rubber pad parts is described herein.
