본 연구는 충청남도 홍성 지역에 거주하는 노인들을 대상으로 임플란트 의료보험 적용 시행 후 임플란트 전· 후의 기능별 만족도 요인을 비교하여 노인들의 구강건강 관련 삶의 질을 향상하기 위한 기초자료를 제공하고자 하였다. 2020년 11월 1일부터 20211년 3월 31일까지 충청남도 홍성군에 거주하는 55세 이상을 대상으로 설문조사를 하였다. 저작, 사회적, 심리적 기능을 조사하여 Likert 5점 척도를 사용하였고 기능별 만족도 비교를 위해 paried T-test를 실시하였다. 임플란트 시술 전·후에 대한 저작 기능, 사회적 기능, 심리적 기능에 대한 모든 문항에서 임플란트 시술 전보다 시술 후에서 유의적으로 높게 나타났다(p<0.001). 임플란트 시술은 노인의 구강건강 뿐만 아니라 삶의 질 변화에도 많은 영향을 주므로 노인의 구강건강 증진을 위해서 노인들의 구강 건강 문제와 임플란트에 대한 연구가 더 많이 시행되고, 그에 따른 방안이 필요하겠다. This study aimed to provide basic data for improving the quality of life related to oral health of the elderly by comparing the satisfaction factors by function before and after implantation targeting the elderly living in Hongseong, Chungcheongnam-do. From November 1, 2020 to March 31, 2021, a survey was conducted targeting people aged 55 or older living in Hongseong-gun, Chungcheongnam-do. A Likert 5-point scale was used to investigate chewing, social, and psychological functions, and a paried T-test was conducted to compare satisfaction by function. All factors for masticatory, social, and psychological function before and after implant surgery were significantly higher after implant surgery than before implant surgery(p<0.001). Implant surgery has a great influence on not only the oral health of the elderly but also the change in the quality of life, so more research on this is needed and measures are needed accordingly.

뷰티NGO를 통한 지역사회 뷰티서비스 전략

최에스더 ( Choi Esther ) 한국미용학회 2017 한국미용학회지 Vol.23 No.5

Local community is a settled living place when people interact socially, have common culture, and share sense of unity concerning the community. Therefore, it is mainly composed of certain region, resident, and community spirit. Especially, among those constituents, residents act as primary protagonists of local community since traits of self-governing body and quality of life can be decided according to their community spirit. Republic of Korea (South Korea) initiated the era of provincial self-government when there was an election of local council members in 1991, and this year has been a twenty-six years. Nevertheless, isolated and socially disadvantaged class people from every local community are increasing because the gap between rich and poor is getting wider and deeper. Socially disadvantaged class people are definitely diverse. For instance, low-income aged people, single-parent family, North Korean defector, multicultural family, homeless people, and disabled people are all our neighborhoods; therefore, this society has to look after all those people with great responsibility. The number of non-governmental organization(NGO) is increasing quite rapidly to from approximately 2,000 in 1997 to 12,894 on September 2015. This growth came both from the introduction of local autonomy and from rising civil consciousness about participation. There are many kinds of NGOs: social welfare, environment, youth, juvenile, culture, physical, volunteer work, woman, education, and etc. Those all NGOs have their own pursued goals; among them, NGO about beauty can play a significant role to develop local community following these two reasons. First of all, beauty NGO is based on personal and voluntary participations to achieve “public goods” with beauty expertise. Secondly, taking good care of the way one looks and desire to have beautiful appearance are common interests to everyone. Thus, the main purpose of this research is setting a beauty-service strategy for alienated disadvantaged groups of local community. There are three ways to accomplish the purpose of this study; at first, it needs to formulate necessity and goal of beauty NGO. Secondly, it has to be analyzed the fields and characteristics of beauty service to serve local community. Thirdly, it needs to classify beauty-service recipient and comprehend their characteristics. Finally, the last purpose of this study is constructing desirable regional community which takes care of our neighborhoods and leads happy lives altogether.

최에스더 ( Esther Choi ) 한국미용학회 2020 한국미용학회지 Vol.26 No.6

As the aging population intensifies, the number of elderly people is increasing. In particular, the perception of parents’ support and family values are changing around small households, so the size of the elderly people living alone is increasing. The purpose of this study is to analyze how Tactil Care affects the depression and self-esteem of elderly women living alone. Moreover, it aims to arrange academic research infrastructure by developing specific Tactil Care programs and exploring the effects of sustainability through this study. It is expected that it will extend both life and healthy expectancy. The research method is based on in-depth interviews, and it is mainly investigated how the untact society caused by COVID-19 affect their lives. In addition, the status of health and appearance management and the differences in depression and self-esteem before and after Tactil Care were analyzed. The participants in this study have the following characteristics: all of them are in their 80s and they have been all married. There were the largest number of conditional recipients living on a monthly rent. Furthermore, most of them suffer from social isolation and economic distress, and most of them required to manage their health life since they have chronic diseases and orthopedic-related diseases. To sum up, overall, depression decreased and self-esteem increased after the Tactil Care. In conclusion, it is thought that the comprehensive and integrated support system which can maintain the daily lives for seniors should be improved as soon as possible in preparation for the post COVID- 19 era. It is necessary to provide support for self-reliance by operating public facilities for elder citizens such as senior centers and welfare centers and untact support system as well. Research should also continue to develop more specific Tactil Care programs which can improve the quality of life for female elderly living alone. This can lower the depression caused by the stress COVID-19, and it can increase their self-respect of themselves.
