This study aimed to analyze the impact of mental strength on the competitive performance of student Taekwondo sparring athletes. A total of 343 middle school, high school, and university students registered as Taekwondo sparring athletes with the Korea Taekwondo Association were conveniently sampled. The Mental Toughness Test developed by Loehr was utilized after expert consultations. Data analysis involved t-tests and one-way ANOVA to assess the levels of mental strength sub-factors based on general characteristics, followed by post hoc tests using the Schéffe method for intergroup comparisons. Correlation analysis and multiple regression were conducted to examine the relationship between sub-factors of mental strength and competitive ability. The results indicated significant differences in mental strength sub-factors-confidence, level of awakening regulation, visualization and mental imagery regulation, motivation level, positive energy, and attitude control-based on gender and age among Taekwondo sparring student athletes. In terms of perceived competitive ability, significant differences were found based on age and sports experience. Consequently, beyond psychological training, the study revealed that age and diverse experiences positively influence specific aspects of mental strength among Taekwondo sparring student athletes. Therefore, coaching and training for these athletes, particularly during middle and high school years, should incorporate psychological aspects alongside diverse competition experiences and training to help overcome performance evaluation anxieties during matches.

Objective: About one-third of college students are exposed to stress to the point that their academic performance is negatively affected. To provide useful information for managing the mental health of young people by analyzing the perceived stress level, depression level, and life satisfaction according to the amount of physical activity and the level of muscular strength in male college students. Design: A cross-sectional study. Methods: Among 304 students who participated in the health exercise class at Sahmyook University in Seoul, the amount of physical activity and the level of muscular strength were divided into 3 quartiles, respectively, and the perceived stress level, depression level, and life satisfaction were analyzed through one-way ANOVA. The physical activity level and muscle strength level of the subjects were ranked, divided into 3 groups, and the difference in variables according to the group was verified. Results: There was no difference in perceived stress level, depression level, and life satisfaction according to the amount of physical activity, but statistically significant differences were shown in perceived stress scale(p=0.008) and life satisfaction(p=0.030) according to muscular strength. Conclusions: Policies to increase physical activity are important to improve and manage the mental health of young people, but it is judged to be more meaningful to provide an environment that can improve muscular strength.

This study investigated the factors associated with HINT-8 (Korean health-related quality of life instrument with eight items), including health habits, hand grip strength, chronic disease, chewing function, mental health, and nutrient intake. In this study, the health-related quality of life (HRQoL; HINT-8) was assessed using the data from the 2019 Korea National Health and Nutrition Examination Survey (KNHANES VIII) among Koreans aged over 65, with HINT-8 being evaluated based on the general characteristics. Of the participants from KNHANES VIII, 1,455 subjects were analyzed using SPSS statistics complex samples (Windows ver. 27.0). The HINT-8 score was significantly lower in females and in those aged 75 years or older, lowest educational level, lowest income level, and single households. Logistic regression analysis, adjusted for the general characteristics, revealed a significant association between a lower HINT-8 group and various factors: low aerobic physical activity (OR=1.71, 95% CI=1.25~2.35), low hand grip strength (OR=1.34, 95% CI=1.02~1.78), chewing difficulties (OR=2.17, 95% CI=1.62~2.92), poor self-rated health status (OR=6.11, 95% CI=4.42~8.45), stressful mental status (OR=3.57, 95% CI=2.27~5.63) and poor calcium status (OR=1.45, 95% CI=1.11~1.88). On the other hand, this study could not reveal a significant association between a lower HINT-8 group and factors such as smoking, drinking, chronic disease, and nutrient intake status, except for calcium intake. This study suggests that HINT-8 is associated with aerobic physical activity, hand grip strength, chewing function, mental health, and calcium intake, but not with smoking, drinking, chronic disease, and nutrient intake.

Purpose: The purpose of this study was to determine the effects of a Health Maintenance Program on physical functions and mental health of the elderly in nursing homes. Method: Sixty elderly(over 65 years old) in a randomized control study participated in a 16-week group-based intervention including functional exercises and health education. The participants were divided into 3 groups(Health Maintenance Program Group, Supportive Music Exercise Group, and Control Group) of 20 elderly each. Data was collected from Dec. 1st, 2005 to Mar, 30th, 2006. Physical function of lower body strength was assessed using a 30-second chair test, flexibility was assessed using a sit-and-reach test, and static balance was assessed by the ability to balance on one leg with open and closed eyes. Depression was assessed using the Korean Form of the Geriatric Depression Scale and self esteem was assessed using Rosenberg's Self Esteem Questionnaire. Data was analyzed by Chi-square test, One-way ANOVA, and Repeated measure two factor analysis. Results: A Health Maintenance Program significantly increased muscle strength, flexibility and static balance, but depression and self-esteem scores were not significantly changed. Conclusion: Findings demonstrated that a Health Maintenance Program was more effective on physical function than mental health of the elderly in nursing homes.

The purpose of this study is to develope a case management education program for employees in the long-term mental health care facilities to reflect strength perspective and analyze the program's effectiveness. The participants in this study were 30 employees working in the long-term mental health care facilities in Seoul and Gyeong-gi regions(15 each), and the program's effectiveness was verified with those participants. The total 13 sessions of the education program was offered: three hours per session, and one session a month. The perception on clients(social distance, attitude towards mentally disorder people) and workers' competence(burnout, empowerment) were used as the measuring tool to verify the effectiveness of case management education. For data analysis, technical statistics and t-test were used in this study. As a result of the analysis, the social distance between the employees in the long-term mental health care facilities who participated in the case management education and clients decreased in relation with perception on clients, and attitude score towards clients improved. It was also verified that burnout decreased, and that empowerment improved in relation with the competence of the employees in the long-term mental health care facilities.

The purpose of this study is to examine the effects of negative life events on mental health and to explore possible main and moderating effects of spousal support on mental health with a focus on gender differences. The data for this study were taken from a nationwide random sample of 1,504 married men and women ranging in age from 30 to 59 through structured questionnaires. The data were analyzed using the SPSS WIN program which was used to calculate frequency, mean, 1-test, multiple regressions. The main results were as follows: First, by examining mental health of Korean men and women, women were more likely than men to experience higher levels of depression. Second, there was no gender difference in the sum of experience of negative life events, therefore the date of this study did not support the differential exposure hypothesis. In addition, men perceived more support from their spouses than women. Third, results show that especially the event concerning with job/financial problems has negative impacts on mental health of both men and women, and vulnerability to undesirable life events was not found. Fourth, spousal support is associated with better mental health regardless of gender, and it reduces the harmful effects of life events concerning with job/financial area for both men and women. Also, spousal support reduces the magnitude of the harmful effects of life events concerning with health of men. This study focused on the impact of negative life events and the couple process. It was possible to explore the strength of social support provided from spouse of most importance to the individuals. These results affirm the importance of supportive relationships between couples as a buffer, mitigating harmful effects of negative life events on mental health.
