The authors experienced a case of a difficult decannulation in a 4 years old boy, in which. case decannulation was possible 2 years later a tracheostomy. Some immunoglogical phenomena could be considered in this case as though cancer can remiss spontaneously. Such complications of tracheostomy as subglottic edema and perichondritis could become relatively less troublesome to breathing during his aging process. And another reason for the easy decannulation is considered as the patient could be accustomed to breathing through natural air pathway by continual cannula corking training.

Brewing with buckwheat as an ingredient has been proven to be successful in several previous studies. However, few studies have focused on the effects of buckwheat on the rutin content and antioxidant activity of beer. In order to develop a lager beer with high rutin content and desirable sensory characteristics, tartary buckwheat malt was used as a brewing adjunct. The results showed that the rutin-degrading enzyme was the key factor affecting the rutin content in the wort and beer. Compared to beer made using the common mashing method, the rutin content in the buckwheat beers produced using an improved mashing method was approximately 60 times higher. The total flavonoid contents in buckwheat beers also depended strongly on the mashing methods, ranging from 530.75 to 1,704.68 mg QE/l. The rutin-rich beers also showed better oxidative stability during forced-aging. Meanwhile, the buckwheat beers were found to be acceptable in terms of the main quality attributes, flavor, and taste.

Purpose: This study aims to obtain basic data for conceptual establishment of sports participation and perceived benefits by considering prior research on the effects of sports participation to derive variables for perceived benefits of sports participants. Research design, data, and methodology: This study used an integrated literature review. A conceptual model is designed with reference to a prior study by adopting a guiding theory. Based on the key words. The literature collection was conducted online, and the reference period for the literature collection was for studies published between 2015 and 2020. Results: First, a total of seven related variables were derived from the literature analysis related to sports participation and physical benefits. Second, a total of six variables were derived from the literature analysis related to sports participation and mental benefits. Third, a total of four related variables were derived through a literature analysis related to sports participation and social benefits. Conclusions: Health fitness, objectified body consciousness, and social body shape anxiety, including body composition, approach physical benefits among perceived benefits through sports participation, and physical self-efficacy and physical self-concepts are related to physical benefits but are also shown to be related to mental benefits. And successful aging is seen to be close to social benefits and related to some mental benefits. Mental and social benefits can be seen as the variables derived from the results being related to the benefits, and more in-depth exploration of perceived benefits is needed.

Polyploidization is a process by which cells are induced to possess more than two sets of chromosomes. Although polyploidization is not frequent in mammals, it is closely associated with development and differentiation of specific tissues and organs. The liver is one of the mammalian organs that displays ploidy dynamics in physiological homeostasis during its development. The ratio of polyploid hepatocytes increases significantly in response to hepatic injury from aging, viral infection, iron overload, surgical resection, or metabolic overload, such as that from non-alcoholic fatty liver diseases (NAFLDs). One of the unique features of NAFLD is the marked heterogeneity of hepatocyte nuclear size, which is strongly associated with an adverse liver-related outcome, such as hepatocellular carcinoma, liver transplantation, and liver-related death. Thus, hepatic polyploidization has been suggested as a potential driver in the progression of NAFLDs that are involved in the control of the multiple pathogenicity of the diseases. However, the importance of polyploidy in diverse pathophysiological contexts remains elusive. Recently, several studies reported successful improvement of symptoms of NAFLDs by reducing pathological polyploidy or by controlling cell cycle progression in animal models, suggesting that better understanding the mechanisms of pathological hepatic polyploidy may provide insights into the treatment of hepatic disorders.

Purpose: This study was conducted to identify relationships among Yangsaeng, activities of daily living (ADL), and physical activity in the elderly in Korea. Methods: A total of 257 subjects (ranged 60-88 yr of age) was recruited through convenient sampling. Data were collected with a self-reported questionnaire from March 2 through 25, 2009. Collected data were analyzed with SPSS/PC WIN 15.0. Results: The level of Yangsaeng was significantly different according to the level of health recognition (p<.05). The level of ADL was differed significantly according to age, successful aging, cohabitation, and health recognition. Physical activity was also significantly different according to age, educational level, cohabitation, (r=.385; p<.05) and health cognition (p<.05). The level of Yangsaeng was significantly correlated with ADL (r=.448) and physical activity (r=.385; p<.05). Conclusions: These findings help in understanding the health status of community-dwelling elders and suggest that promoting the Yangsaeng can be an effective intervention as a health promotion program for the elderly in Korea.

The aging of Korean society is coming to the fore and its speed is unprecedented. Along with the volume rise in the population of the elderly, the rise of the elderly of means and high education stimulates the transition of our focus from "a desire of longevity" to "successful aging". The research objective is to classify groups by the different definitions of disability thinking of the geriatric oral health care. We targeted 34 aged people who live in Pusan Metropolis and analyzed the collected data and classified them into two types. The first type is the 'blunting of taste & oral pain' which is identified as a group. The second type is the 'blunting of taste & lowering quality of life' which is identified as a group. The common positive statements are 'There are some experiences to feel pain on and below tongue, cheek and upper palatine.', 'There are some experiences to feel unsatisfactory life'.

This study aimed to review Korean-written and English-written studies on music intervention for older adults in terms of research variables and type of music application. Electronic databases and music-related journals were searched and a total of 40 studies, 19 Korean-written and 21 English-written studies, were included for analysis. The results showed that music intervention studies for older adults began to be conducted in Korea in the late 1990s and have continuously increased thus far, which is similar to studies overseas. Emotional area, especially depression, was targeted the most frequently in both studies in Korea and overseas. While singing of traditional folk song or popular music were applied the most in Korean studies, listening to classical music or relaxing music was primarily observed in studies overseas. While both studies in Korea and overseas used original music frequently, Korean-written studies used live music and showed tendency to select music based on preferences of participants more than studies overseas. These results indicate that growing population of older adults and increased needs for successful aging have been sufficiently reflected in studies on music-based intervention. Cultural and societal factors might affect the differences between studies in Korea and studies overseas. Future studies on music intervention considering cultural and societal needs of this population from multidimensional approach were also suggested.

This study aims to suggest the academic roles and direction of the social welfare for the elderly in Journal of the Korean Gerontological Society. For this purpose the trends of research on the social welfare for the elderly were analyzed by means of reviewing articles published from 1980 to 2008 in Journal of the Korean Gerontological Society. Out of all published articles, 215 articles were selected on the basis of unanimity among 3 reviewers including this author. First, in 1980s there were very limited numbers of articles. It had been mainly introduced foreign and domestic institutions of social welfare for the elderly and focused on the serious issues for the elderly in aging society. Secondly, in 1990s, there were explosive increases of research in elder welfare studies. The subjects of the articles were diversified and research methods were sophisticated in this period. Thirdly, it showed that the numbers, subjects, and research methods of the articles concerning social welfare for the elderly were enriched and differentiated during 2000-2004. Lastly, the research trends have focused on the issues of successful aging, quality of life, and psychological well-being in consideration of the quality of life for the elderly up to now since 2005. But the research trends have had some limitations in showing only application of theories and models or in simply introducing the knowledge in Western countries. It is necessary to have clear academic identity which can be faithful to Korean Gerontological studies.

The purpose of this study was to study the performance of volunteer work for the elderly from the perspective of self-efficacy and self-extension of the elderly, not from successful aging or productive aging. Through this, the research aims to confirm the expansion of internal growth and self-sufficiency that can occur in old age, and to provide an opportunity to re-examine one's life in old age. In order to verify the purpose of this research, questionnaires were distributed to 300 senior citizens who participated in volunteer activities at the City Hall and the District Office of Busan Metropolitan City over a period of three months from September to November 2018 and used the data from 266 questionnaires for the study, excluding the 34questionnaire answered unfaithfully. The results of the study are as follows. First, the motivation for volunteering activities (value function, social function, understanding function) of the elderly has a positive effect on self-efficacy. Second, the motivation for volunteering activities (value functions, social functions, understanding functions) have a positive effect on self-extension. Third, it has been shown that the elderly's sense of self-efficacy (self-regulation efficacy, confidence) has a positive effect on their self-extension. Fourth, it was found that self-efficacy has a mediated effect on the motivation of the elderly to participate in volunteer activities and the relationship of self-extension. This study identified the relevance of the motivation for volunteering activities of the elderly to influence their effectiveness and self-extension. In particular, the research suggests practical and policy measures for the revitalization of volunteer activities of the elderly by providing a new perspective on the welfare of the elderly by utilizing parameters of self-efficacy, a psychological and social concept for the elderly.

The purpose of this study is to systematize the theory of the Fashion Marketing and merchandi-sing system as well as the strategy for the Mar-keting based on the related variable. Furthermore, this study deals with development of the mark-eting strategy to the relation between consumers and industry. The content conclusion on the research can be outlined as follows : 1. In order to inverstigate how the life-style of consumers affects their sense of fashion, awa-reness of brand, and decision making process of purchase, the life-style of women consumers is classified into 15 types. (1) Acording to the different life-style types, and important difference is found in the consum-ers' sense of clothes, a unique image of outfit and its own favorite image of womanliness. (2) The consumer's awareness of a particular brand has a reasonable relationship with their brand preference and possession of the brands. (3) Their is an important discrimination acco-rding to the life-style types in their brand awar-eness and preference and possesion of brands. (4) The consumers of each life-style type show noticeable difference in the decision making pro-cess of purchase including he motive of purchase, the source of information, the cause of purchase intention, price, the frequency of purchase and the degree of satisfaction of purchased goods. 2. The merchandising system and the market positioning among the fashion industry are compared and analyzed in the following terms ; (1-1) For the purpose of establishing the target market strategy, the industry uses unreasenalbe methods to analyze the life-style of the target customers and the real customers(36%) and the aging phenomenon of brands is remarkable : as much as 37% of brands show over 5 years-old age gap. (1-2) The price setting process depends highly on the cost-plus approach. (1-3) In color planning, too many colors are used in every season(the average number is 22.3) and the investigation of the consumers' favorite color is neglected. (1-4) The manufacturers of successful brands are much likely to employ the textile designer and allow them to develop the various fabrication. (1-5) The regular rate of sales in each season is extremely low(56.04%) : the rate of the succ-essful brands is relatively high at 65%, but that of the unsuccessful as low as 51%. (1-6) 47% of brands reveal the designer-orie-nted fashion merchandising system. The successful brands, on the other hand, show a high rate of merchandiser oriented system. (2) Since the brand positioning is highly cen-tered on each brand image, styles and target age, the new data are presented in this study for the new market development. (3) To set up the target market, the mapping of images between the differentiated market and the consumers is suggersted according to the market positioning of industry and 15 types of the life-styles of consumers.
