This study was conducted as a survey to find out middle-aged persons's housing preferences for a future elderly housing and to grasp background characteristics of persons influencing the preferences and the effect of elderly's aging situations on the changes of their preferences. A sample of 300 middle-aged people was selected purposely from parents of university students living in Gwang-ju city. Questionnaires were administered to parents by students and analysed with SPSS Windows 10 program. Middle-aged persons's housing preferences were differed according to elderly's aging situations, in the case of healthy situation, they tended to prefer to stay present house without their children in irrespective to couple or single, whereas in the case of unhealthy situation, they tended to prefer to live with their children. and couples showed preferences for planned housing for the elderly and singles showed preferences for elderly housing facilities with care services. The most important characteristics of elderly housing among middle-aged people was a places where they can enjoy leisure and provide home-help services, located in the suburbs. Also middle-aged persons were likely to prefer to a green spaces such as garden, path for walking, and madang for the elderly housing. Needs for community care services (NCCS) were required above the average. Among the items of NCCS, a visiting medical examination was the most demanding, and a visiting nursing services, a emergency calling bell, and home repairs were sequently followed in the level of needs. The characteristics of the elderly housing which preferred to and needs for community care services were influenced by middle-aged persons's age, gender, subjective evaluation of economic abilities, tenure status, the cost of living, and the size of housing. This findings suggests that it must to be considered to develop various types of the elderly housing depending on socioeconomic status.

The aging of the population has been in process all over the world including most of advanced countries. With the improvement of living standards and medical technology due to the growth and development of the modern industrial society, the continuous Increase of the average lifespan has led to an abrupt growth in the population ratio of the aged. The senescence is the period where both physical and mental functions get dwindled, and due to a loss of roles in a society and a weakened social bond, the elderly people feel often neglected and isolated. Consequently, the elderly people spend a lot of time in their houses. As this means that the elderly gets higher possibility to stay within housing units and housing complex environment, residents' public space needs to be developed within the housing complex for them. Therefore, constructive programs and plans are required for the elderly who experience distance constraint because of corporal aging, for them to sustain community activities within their housing environment. Contrary to them in the 20th century, the elderly living in the nowadays informational society tend to enjoy their leisure times with arts and cultures and underscore the significance of social exchange under diverse possibility and sustainableness. Thus, it is important to preserve those circumstances to provide continuously them. Thus, the purpose of this paper is to grope a growth direction of residents' public space for the elderly to include them to their community through a socially integrated way by grasping present condition of apartment residents' public space's facilities and to be used practically as a basic housing environment data to raise quality of community life.

To evaluate the protective effect of collagen peptide-coated coffee extract on skin aging, cell viability was measured with a MTT assay using cultured CCD-986sk fibroblasts, and its effect on wrinkles in the skin of hairless mice induced by UVB-irradiation was examined. In addition, its effect on procollagen synthesis and anti-oxidative, and its inhibitory activity against collagenase, elastase, tyrosinase and MMP-1 were analysed. After the 30-minute topical treatment, the animals were exposed to UVB irradiation (60-100 mJ/cm²) for 4 weeks and its intensity increased during the period. Under the experimental conditions set in this study, the skin thickness of hairless mice significantly decreased (11.8-21.3%) compared to the control group. Based on these results, the prolonged oral intake of a collagen peptide mixture with coffee is expected to significantly increase the synthesis of procollagen in dermal fibroblasts, thereby contributing to the alleviation of wrinkling and lowered elasticity due to structural damage to the dermal layer caused by UV. The oral intake of collagen-coated coffee contributes to increasing collagen biosynthesis in a dose-dependent manner and alleviates the symptoms of thickened keratin caused by UV irradiation. However, it did not inhibit the enzymes involved in skin aging, whitening, wrinkle improvement, and antioxidation. Based on the these results, it can be concluded that the intake of collagen peptide-coated coffee extract can be utilized as an alternative material for the prevention or treatment of diseases associated with photoaging.

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.

According to the statistics, Korea is expected to reach a super-aged society in 2025. In preparation for an aging society, The government is making efforts to improve in social activity and welfare for the elderly people. But in case of people who live in urban-rural mixed cities, They can not benefit from traffic convenience that is essential in social activities. For example, surveys and interviews show that, The dwellers(65+ of some urban-rural mixed cities) have many restrictions on social activities because of mobility disadvantage. Therefore, We propose that expansion for the people who need to use the voucher taxi, Increase of the public bus service and rebuilding of the bus stop terminal. We are looking forward to this study will be used as basic data for transportation policy of urban-rural mixed cities across the country.

This study was attempt to derive the aging trajectories of Korean elderly people and identify its characteristics. In particular, this study used the successful aging model of Rowe and Kahn as an analytical framework. Using the Korean Longitudinal Study of Ageing(KLoSA), this study applied group-based multi-trajectory analysis to identify multiple aging trajectories in sample of Korean elder aged 65~74(n=2,682). This study also used several demographic characteristics as baseline predictors to identify the characteristics of each aging trajectory. Five dimensions were analyzed in the multi-trajectory model: chronic disease, physical functional limitation, cognitive functioning, depressive symptom and social engagement. As a result of the analysis, five aging trajectories were identified: successful aging(17.8%), usual aging (33.9%), health declining aging(18.2%), pathological aging(7.9%), and aging with mild cognitive impairment(22.1%). In general, the odds of experiencing successful aging were high in men, low-aged, highly educated, high-income, and spousal elderly. On the other hand, for the elderly, who are under-educated, low-income, and high-aged, there was a high probability of experiencing a relatively difficult aging process. In particular, the odds of experiencing a mild cognitive impairment aging was high in older, lower-income women without a spouse.

As an aging population is increasing, more elderly people are exposed to traumatic stress. Although this issue has received more attention in some literature, it is clear that numerous questions exist in aftermath of trauma exposure in elderly people. In case of Korean elderly suffers, traumatic experience includes the Korean war, military dictatorship and violent demonstration. Studies regarding elderly PTSD is not active and a lot of patients are not still engaged in treatment. We suggest that concerns that are unique to this population are necessary.

Most people have a desire to live longer. According to ancient Chinese and Korean mythology, Dongfang Shuo (Dongbang Sahk) lived for 18,000 years. According to a WHO report, the average longevity of humans has extended from 50-odd years in the 1960s to 75-85 years in 2016. Parabiosis, the joining to circulatory systems of two animals, was described as early as the 1860s. It provides a powerful experimental model to investigate the effects of one animal on its partner animal in vivo. Research on reverse aging is an immensely popular in parabiosis studies. In this review, the origin of the parabiosis model and important historical findings based on parabiosis models are presented. Surprising and debated discoveries in aging research are also introduced. Using heterochronic parabiosis of connecting circulatory systems of a young mouse and old mouse, various groups claim to have identified a reverse aging factor, growth differentiation factor 11 (GDF11), which was significantly reduced in blood of old mice. Although the potential existence of any one factor or factors that could reverse aging remains to be confirmed, studies have shown that the parabiosis model is powerful enough to detect reverse aging factors.

Background: This study aimed to analyze trends in oral health research among people with disabilities. Methods: Data were obtained from 70 oral studies on individuals with disabilities from 2000 to 2024. Keywords were analyzed. Frequency, betweenness centrality, and cluster analyses were performed using NetMiner. Results: The main keywords for oral health research on disabled people were oral health, dental caries, DMFT (decayed-missing-filled-teeth), dental treatment, oral health centers, and disabled children. As a result of the centrality analysis, DMFT had the highest connectivity, followed by disabled children, special care dentistry, oral health behavior, periodontitis, and health insurance. Cluster analysis results of research on disabled people: Group 1, oral diseases and functions of disabled people; Group 2, oral care for disabled children; Group 3, dental treatment for disabled people; Group 4, oral health policy; Group 5, oral care by dental hygienists; and Group 6, conservative dentistry. Conclusion: Considering the increase in the number of disabled people in a super-aging society, research on ways to promote oral health for disabled people, oral health policies, and training of oral health experts for disabled people is required.

This study a secondary data analysis study attempted to identify the factors influencing the successful aging of the elderly in Korea. Using the data of the 7th Aging Research Panel in 2018, 4,106 people over 65 years of age who had at least one non-living child and no missing values in the study variables were enrolled. Data were analyzed by frequency analysis, crossover analysis, independent sample t-test, and binary logistic regression analysis. The results of this study revealed that the factors affecting successful aging among elderly included age, the presence or absence of a spouse, education level, housing type, subjective health, exercise, alcohol drinking, and non-face-to-face contact frequency with non-cohabiting children, and the explanatory power of the variables was 24.1%. In order for the elderly to achieve successful aging, centering on child ties, the frequency of non-face-to-face contact, which can comfort the elderly's life and increase the satisfaction of life in a continuous relationship, is more important than having children live close and meet frequently. Based on this study, various strategies are needed for the successful aging of elderly people who are socially isolated due to concerns about COVID-19 infection.
