Human body is hard to be in perfect balance during walking. Most of time the trunk is supported by one leg and the center of mass(COM) falls to the contralateral side. Thus, dynamic variables such as the velocity of the COM should be considered when gait stability is evaluated. The purpose of this study was to investigate whether the extrapolated center of mass(XCom) which utilized the COM position and its velocity, is appropriate to evaluate gait stability. Ten healthy adults participated in this study and performed 3 different types of gaits(normal(NG), hands on waists(HWG), and hands on shoulders(HSG)) onto 4 different types of obstacle(obstacle height: 0%, 30%, 40% and 50% of leg length). Medio-lateral Com-CoP and XCom-CoP inclination angle were calculated during support phase. For all condition, greater M-L XCoM-CoP inclination angles were found(p<.05) compared with those of matched obstacle height CoM-CoP. Especially, M-L XCoM-CoP inclination angle at 50% height revealed the best condition for monitoring dynamic stability. Significantly increased in M-L XCoM-CoP inclination angle was found(p<.05) as obstacle height increased on NG and HWG.

Purpose: This study was a descriptive study to identify the factors affecting the dementia prevention behavior of elders in rural communities. Methods: The participants in this study were 125 elders aged 60 or older who lived in Eup or Myeon areas of P city. For data analysis, SPSS/WIN 22.0 was used to perform descriptive statistics, t-test, ANOVA, Pearson correlation, and linear multiple regression and mediated effects. Results: Scores for dementia recognition, dementia attitude and dementia prevention behavior averaged 5.6±2.50 points in the 0~11 range, 38.8±4.59 in 14~56 and 20.2±3.59 in 10~30 respectively. Dementia recognition (a), dementia attitude (b), dementia prevention behavior (c) and the number of chronic diseases of the elders (d) were positively or negatively correlated with each other (rab=.29, p<.01; rbc=.26, p<.01; rac=.36, p<.01; rad=-.29, p<.01; rcd=.19, p<.05). Factors affecting dementia prevention behavior were dementia recognition, dementia attitude, and degree of dementia interest. When the number of chronic diseases affects dementia prevention behavior, dementia recognition has a mediating effect. Conclusion: In order to prevent dementia among elders in rural areas, appropriate management of chronic diseases and provision of appropriate dementia-related education and information to enhance dementia recognition should be provided.

This study attempts of analyze empirically the living status of the elderly in Korea by finding out the problems of it in the family and by clarifying the influences of the family environmental variables and the values on the adjustment of the aged. To carryout the aim of this study, the causes and the patterns of the problems for the aged had been found out through the review of literature. Based on them the questionnaire was prepared including the questions of the values, family environmental vriables as well as the degree of satisfaction of thier liver and the extent of life interchange. The former variables were taken as independent and the latter were taken as dependent variables, so that the relationship between the two variables could be exemplified. The 400 aged over 60 living in Seoul and the other cities were selected through the purposive sampling and interviewed. The answers of the 376 respondents, 94% of the sample, were analyzed for this study. The following results have been found out through the various statistical analysis such as frequency distribution, chi-square test, pearson's correlation, analysis of variance and cluster analysis. At first, the results from the examination of the frequency distribution regarding the living status of the aged are; I) sixteen percent of the respondents living with their married offspring were receiving economical support, though they pointed out the problems of the extended family are the inconveniences with their children (60%) and simpleness (20%) of their livers. It seems that the aged in Korea are poor and have negative opinion on the relationship with their offspring even if they live in the same house. Secondly, it has been found out that the family environmental variables, especially such as sex, occupation, residence, education, level, living ability and the family type, play and important role not only on the degree of satisfaction of their liver but also on the extent of interchange of their lives. However, the variables such as religion and whether the spouse is alive or not do not play and important role. Thirdly, the reported main reasons of their delightness were healthy life (1.87%), the well-being of their offspring (2.08%), the spouse's long life (3.38%), religious activity (5.05%), the hobby activity (4.31%) and the participation in the social activity (5.05%). While, they mainly concern about the illness (1.98%), offspring (2.00%), econmic difficulties (3.39%), inharmonious home (3.81%) and the despicable treatment (3.81%). The respondents wer classified into two groups, they are dependent and independent, using cluster analysis. Health, social activity, offspiring, religion, couple's long life among the factors which lead them to be delighted were turned out to be statistically signhificant at 0.01 significance level between the two groups. As far as their worrisome matters are concerned, health and economic difficulties were significantly different between the two groups. Fourthly, regarding the life interchange, it has been proved that there is a statistically significant differences betwwen the two groups in the economic and the emotional satisfaction, help for ordinary life, status in the family, subjective and objective relationship with offspring, but not in economic dependency and the activity status. Fifthly, it has been noted that there is a high correlation between the degree of life's satisfaction and the extent of life interchange. On the basis of the results mentioned above, it could be concluded taht; i) The majority of the aged in Korea are not economically active, and thus they live with their married offspring even of they have a negative opinion on the subjective relationship with them. This can be pointed out as the main problem of the aged and thus it needs to be studied further. ii) the environmental variables such as age, sex education level, family type and occuption (which can not be changed by their effrot) turned out to give an important effect on the extent of the life interchange among the aged. iii) The respondents who are identified as independent group have a higher degree of life satisfaction and family status than the group identified as defendent. Thus, it can be inferred that it is possible for them to adjust their life by making an effort to modify themselves. iv) The high correlation between the extent of life interchange and the degree of life satisfaction indicates that the elderly themselves can adjust in order to obtain the higher degree of life satisfaction. Therefore, the following suggestions are derived from this study. First of all, the aged should try to be psychologically independent. Second, they need to control themselves in order to achieve self-assurance. Third, the community have to prepare a program of self-development for the aged. Fourth, the social welfare policy that can solve the problem of illness and poverty of the elderly should be introduced, so that their minimum requirements can be satisfied.

We are facing an era of automation where artificial intelligence works and an era of super-aging, where birth is rapidly declining. In this paper, we intend to perform the creation of an autobiography in conjunction with the generation integrated narrative storytelling, thereby exploring the potential for visual storytelling that can be extended to a variety of media format. The visual autobiography production program confirmed through an interview with the production participants that grandparents, grandchildren and granddaughter together became the main characters in the documentary, a valuable opportunity to reflect on their past memories and lives and recognize their meaning of life. The visual storytelling education program model and media life service presented in this paper will be shared by the youth and the elderly generation together and contribute to the 'sympathetic culture' as a social integration program.

Purpose: The purpose of this study was to compare the effects of stretching exercise and aquatic exercise program on flexibility, pain and quality of life (QoL) in patients with osteoarthritis. Methods: Fifty elderly women were assigned either to the stretching exercise (SEG, n=25) or to the aquatic exercise groups (AEG, n=25) after 6-week self-help education program. SEG carried out supervised stretching exercise and water exercise training program was conducted by AEG (60 min/day, 2 days/wk) for 8 weeks. Flexibility, pain, and quality of life were measured by Senior Fitness Test Manual (Rikli & Jones, 2gr5), pain rating scale (0-10) and the questionnaire by World Health Organization Quality of Life BREF (Min et al., 2gr0), respectively. Results: Both SEG (all, p&H;.05) and AEG (all, p&H;.05) increased left upper and lower-body flexibility, measured by a measuring tape. Pain significantly decreased both in SEG (p=.000) and AEG (p=.004). Quality of life was significantly improved only for the SEG. Conclusion: The 8-week stretching exercise program would significantly improve flexibility, pain control and QoL in patients with osteoarthritis.

Objectives : This study was conducted to examine social factors associated with problematic drinking among middle- and older-aged men in South Korea. Methods : The data were collected from the baseline survey of the Korean Longitudinal Study of Aging, and the sample consisted of 3,631 men between 45 and 64 years of age and 1,173 men aged 65 or older. This study employed variables identifying various socioeconomic features, social ties, and health-related factors. Logistic regressions were used for the data analysis. Results : Middle-aged men having frequent social relationship with close persons were significantly more likely to be problematic drinkers than those having less frequent social relationships with close persons. Lower education, unemployment, smoking, and depression were associated with problematic drinking only among middle-aged men. Conclusions : We suggest that health professionals develop specific intervention strategies that could lead to more moderate alcohol habits and better health in middle aged Korean men who are actively engaged in social networks. In addition, health professionals need to focus more on the unemployed, lower educated, depressed, and smoking groups for early detection of problematic drinking among middle-aged Korean men.

Purpose: The study was conducted to identify factors influence suicidal ideation among older adults with osteoarthritis. Methods: This study used a cross-sectional design with secondary analysis of the Korean National Health and Nutrition Examination Survey. Data for 174 men and 939 women who aged${\geq}65$, and were diagnosed osteoarthritis from the Korea National Health and Nutrition Examination Survey 2010~2012 were included. Suicidal idea, age, sex, education, marital status, living alone, income, body mass index, smoking and alcohol use, exercise, perceived health status, activity limitation, joint pain and stiffness, depressive mood, and perceived stress were measured. Influencing factors and odds ratios were analyzed using complex sample multivariate logistic regression. Results: In the results, 29.9% of the elderly with osteoporosis had suicidal idea. The adjusted odds ratios (ORs) of suicidal ideation were significantly higher among those over 80 years older (OR=2.88, 95% CI=1.49~5.58), those with depression (OR=4.01, 95% CI=2.66~6.04), and those with high levels of stress (OR=2.76, 95% CI=1.79~4.24). Conclusion: Therefore, older adults with osteoarthritis should be screened for depression and stress to decrease suicidal ideation and prevent suicide attempt.

Excessive body weight gain during the growth period of early life may predispose individuals towards obesity and metabolic disorder in later life. We investigated the possibility of using the food efficiency ratio as an early indicator for predicting susceptibility to diet-induced obesity and insulin resistance. Four-week-old, prepubertal, male Sprague Dawley rats were divided into obesity-prone and obesity-resistant groups based on food efficiency ratio values after five days on a high-fat diet. Metabolic parameters measured after 2, 6, and 10 weeks, and specific phenotypes were compared with each group. Obesity-prone rats had higher increases in body weight and fat mass compared to obesity-resistant rats over the study period. Obesity-prone rats became glucose intolerant early in this study and remained so throughout the experimental period, with increases in fat weight and leptin levels occurring first, followed by increases in insulin level. Gluconeogenesis and insulin resistance significantly increased in obesity-prone groups in which activities of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase were increased and glucokinase activity decreased. Higher food efficiency ratio at an early age was closely correlated with body fat accumulation, hyperleptinemia, and hyperinsulinemia of middle and elderly age. We suggest a high food efficiency ratio in prepubertal subjects may be a useful predictor of future obesity and insulin resistance.

This study was conducted to research into the recognition level of employment and overseas employment on 173 students majoring in dental technology at two colleges in Daegu metropolitan city and Jeju self-governing island through questionnaires which are recorded individually. The results are as follows. 1. About 31.8% students chose dental technician department taking their aptitude into consideration when they entered college. 52% students gained information about dental technology through internet, and 57.3% students among them, which was the highest level, were under age 20. 2. 48.6% students responded that they thought the level of satisfaction with major was average and there was a difference according to their ages among the level of satisfaction or dissatisfaction with their major and the previous knowledge of major they had gained before entering college. 75.1% students said they wouldn't transfer to other major even if they were given the chance, which was much higher than the opposite case. And only 2.3% students had dissatisfaction at their major, which means students majoring dental technology evaluate their major positively. 3. Most students(58.4%) wanted to get a job for living cost and 53.2% students took advice from their seniors or elderly people in choosing their jobs. 64.7% students answered they should have professional skills to get a good job, which was different according to their ages. In addition, 51.4% students of dental technology department regarded the opportunities to exert their abilities as the most important element in choosing their jobs. That means students value self-decision and selfrealization when they choose their jobs. 4. The majority of students(32.9%) preferred to work at the dental laboratory in dental college hospital as their workplace. Moreover, seniors over age 21 wanted to work in the field of porcelain and juniors under age 20 preferred to work in the implant part concerning the field which students wants to work. 5. About 91.3% students have ever heard about overseas employment and wanted to work abroad if given the opportunities(77.5%). This points out students have much interest in overseas employment and positive attitude. And there was a difference according to age and grade in case of the preferred country when they work abroad 6. The main barrier to overseas employment was a lack of communication ability(63.0%), therefore, students thought foreign language education should be activated to improve overseas employment(26.0%). To show this more specifically, juniors thought foreign language education and internship are most important factors(both are 21.4% alike), while seniors thought foreign language education is essential(24.6%) as a way to improve overseas employment. Students also thought that participation in language study club helps to prepare for overseas employment(69.4%). When putting all these survey results together, it's very important to develop people in advance who have job ability and language ability necessary for overseas employment as well as to improve job awareness in the field of dental technology. Consequently, it's needed to seek for various ways to get a overseas job through foreign language education and overseas internship.
