In Korea, the elderly is defined as the person aged over 65 and the disabled is defined as the person who is registered with Ministry of Health and Welfare. In 2008, the elderly with disabilities was about 770,000. Korea was already poised for an aging society in 2000 and is ahead of and aged society in 2018 and a super aged society in 2026. So, the number of the elderly with disabilities will continue to grow. Various oral diseases can be seen in the elderly with disabilities due to the systemic disease and impaired self oral care, in addition to the physiological aging. Particularly, we should be care for the aspiration pneumonia, which is the major cause of the death of the elderly. As a professional for the special care dentistry, we should understand the general and dental, individual characteristics of the elderly with disabilities and do proper oral care and treatment. Thereby, the quality of life of the patients might be improved.

Korean society is running fast toward a super aging society. This means that new solutions for new problems of aged people are needed. An important area to prove is the aging-friendly neighborhood environments supporting casual contacts and meetings of old residents. This study attempts to suggest neighborhood design indicators which support casual contacts and meetings of old residents. The subjects were 24 professionals who had studied on housing environment for the elderly. They answered through the on-line questionnaire. The questionnaire consisted of items which evaluate the appropriateness of classification of neighborhood area and the indicators of each area using 5-points Likert scale. Also open questions asking adding or eliminating areas or indicator and other opinions were included. On the basis of these answers, the aging-friendly neighborhood design indicators supporting contacts and meetings of old residents was developed. They are consisted of 7 areas in neighborhood and 60 indicators. Those areas were semi-public residential area, commercial area, cultural & educational area, health & medical area, park & green area, walkway, and public traffic facilities. This would be used to design the neighborhood environments that are aging-friendly and facilitating casual contacts and meetings of all residents, especially old residents.

Background: Oral health is an important element of well aging. And oral health also affects overall health, mental health, and quality of life. In this study, we sought to identify oral health influencing factors and research trends for well-aging through text analysis of research on well-aging and oral health over the past 12 years. Methods: The research data was analyzed based on English literature published in PubMed from 2012 to 2023. Aging well and oral health were used as search terms, and 115 final papers were selected. Network text analysis included keyword frequency analysis, centrality analysis, and cohesion structure analysis using the Net-Miner 4.0 program. Results: Excluding general characteristics, the most frequent keywords in 115 articles, 520 keywords (Mesh terms) were psychology, dental prosthesis and Alzheimer's disease, Dental caries, cognition, cognitive dysfunction, and bacteria. Research keywords with high degree centrality were Dental caries (0.864), Quality of life (0.833), Tooth loss (0.818), Health status (0.727), and Life expectancy (0.712). As a result of community analysis, it consisted of 4 groups. Group 1 consisted of chewing and nutrition, Group 2 consisted oral diseases, systemic diseases and management, Group 3 consisted oral health and mental health, Group 4 consisted oral frailty symptoms and quality of life. Conclusion: In an aging society, oral dysfunction affects mental health and quality of life. Preventing oral diseases for well-aging can have a positive impact on mental health and quality of life. Therefore, efforts are needed to prevent oral frailty in a super-aging society by developing and educating systematic oral care programs for each life cycle.

As of November 1st 2010, 59% of overall residences in Korea are apartments with 8,185,000 households and when including the multi-unit houses, 71.0% of the overall residences are multifamily houses. The apartments have become the most universal form of residence in Korea and its' relative weight will continuously increase in the future. Meanwhile, Korea has turned into aging society in 2000 and will turn into the super-aged society by 2026 to display the world's fastest speed for aging. Majority of the elderly will spend their declining years in apartments. To understand the residence consciousness and its' properties for unit housing of the elderly residing in apartments, the present study obtained the following results through surveying the 541 nationwide samples. First, the elderly most prefer the mid and high levels(6-9th floors, or 10-15th floors) of apartments. Second, the elderly couples most prefer areas of $85m^2$ while single elderly most prefer $60m^2$. Third, the elderly feel the most inconveniences in bathrooms and showers. Fourth, safety accidents in dwelling of the elderly have no significant correlation with age, gender or their possessed diseases. Fifth, the elderly displayed high satisfaction for their bedrooms. Sixth, there were less tendencies for elderly to feel lack of storage spaces or conduct remodeling. As a result of the analysis, all apartment houses of Korea must support the physical aging of residents and prevent safety accidents in houses to enable Korean aging in place.

This study has investigated the effect of aging treatment on the microstructure and mechanical properties of Mg-6Al-xZn(x = 1.5, 2.5) alloys fabricated by the squeeze casting process. The microstructures of as-squeeze cast were composed of pro-eutectic ${\alpha}$, super saturated ${\alpha}$ and ${\beta}(Mg_{17}Al_{12})$ compound. Aged at both $200^{\circ}C$ and $240^{\circ}C$, Mg-6Al-xZn alloys showed the peak hardness due to the formation of ${\beta}(Mg_{17}Al_{12})$ precipitates. The discontinuous precipitates of the lamella type are predominant at $200^{\circ}C$ aging treatment, while the finely dispersed continuous precipitates were dominant at $240^{\circ}C$ aging treatment. Mg-6Al-xZn alloys fabricated by the squeeze casting process had the better combination of tensile strength and elongation compared to the conventionally cast alloys. As zinc contents increased, the tensile strength was increased by the solid solution strengthening effect of zinc.

China has already entered the aging society and is predicted to become a super-aged society in 2020. The recent studies identified that the elderly has more interest in 'Aging-in-Place' which emphasizes deinstitutionalization since welfare facilities such as care homes and silver towns have separated the elderly from their local communities where they used to live in. The aim of this research is to propose a promising way for smart housing services who support the elderly's living in their homes, China. This research is to investigate the elderly's life and to identify their demands on housings for implementing such smart services. The elderly's living in apartments in Luoyang city, China, were investigated through interviews using a questionnaire survey. The results show that smart housing services should be provided to support the elderly's health, safety, leisure activities, comfortable living, and social relationships sustainably. In addition, such smart housing services should be intuitive since the elderly need to use easily smart services for their autonomous life in their homes. The smart housing services should be developed in the direction of enhancing the elderly's healthy and desirable life, and lessening their discomforts due to aging.

Ni-base superalloy Haynes 282 was developed as a gas turbine material for use in the ultra-super-critical stage (USC) of next-generation coal-fired power plants. Temperatures in the USC stage exceed $700^{\circ}C$ during operation. In spite of its important role Haynes 282 in increasing the performance of high-pressure turbines, as a result of its high-temperature capability, there is little information on the microstructure, deformation mechanism, or mechanical properties of the cast condition of this alloy. The aim of present study is to examine the creep properties of cast alloy and compare with wrought alloy. The ${\gamma}^{\prime}-precipitates$ were coarsen with the increase of aging time ranging from 8 to 48 hrs. A creep test performed at $750^{\circ}C$ showed faster minimum creep rate and shorter rupture lifetime with the aging time. A creep test performed showed only a slight difference in the rupture life between cast and wrought products. Based on the creep test results, the deformation mechanism is discussed using fractographs.

In this study, the influence of thermal aging on structural integrity is investigated for Gr. 91 steel. A commercial grade Gr. 91 steel is used for the virgin material, and service-exposed Gr. 91 steel is sampled from a steam pipe of a super critical plant. Time versus creep strain curves are obtained through creep tests with various stress levels at 600 ℃ for the virgin and service-exposed Gr. 91 steels, respectively. Based on the creep test results, the improved Omega model is characterized for describing the total creep strain curve for both Gr. 91 steels. The proposed parameters for creep deformation model are used for predicting the steady-state creep strain rate, creep rupture curve, and stress relaxation. Creep-fatigue damage is evaluated for the intermediate heat exchanger (IHX) in a large-scale sodium test facility of STELLA-2 by using creep deformation model with proposed creep parameters and creep rupture curve for both Gr. 91 steels. Based on the comparison results of creep fatigue damage for the virgin and service-exposed Gr. 91 steels, the thermal aging effect has been shown to be significant.

According to the provisions of the United Nations, the proportion was 65 years of age or older population is 7% more than in the total population aged society. Due to the rapid decrease fertility and medical technologies and the improvement of living standards, the average life expectancy has emerged as an aging society. In the case of our country, and in 2011 the proportion of the population aged 65 and over 11.4%, the future is even faster aging rate is expected to launch in 2026, the super aged society. The days went by relying on caring for personal piety. Nursing crime is often due to the patriarchal family culture and afford. To care for patients with severe human or plant in the home, not to assume that society. Expanding the scope of long-term care insurance service person and the family burden reduced through measures to apply for health insurance, nursing care can prevent crime.
