The purpose of this study was to understand the interrelationships between customers' perception of service encounter elements, customers' emotional response and customer satisfaction in a family restaurant. Based on a total of 408 samples, this study reviewed the reliability and fitness of the research model and verified a total of 4 hypotheses using the Amos program. The hypothesized relationships of the model were tested simultaneously using a structural equation model (SEM). The proposed model provided an adequate fit to the data, ${\chi}^2$=821.151 (df=333), CMIN/df 2.466, GFI .878, NFI .927, IFI .955, TLI .949, CFI .955, RMSEA .060. The results showed that human factor ($\beta$=.426) and physical factor ($\beta$=.266) as service encounter elements in family restaurants were indicated to have a positive (+) influence on customers' positive emotion. For influence of customers' negative emotion, human factor ($\beta$=-.157) was surveyed to have a negative (-) influence. Also, customers' positive emotion ($\beta$=.716) and negative emotion ($\beta$=-.081) had significant effects on customer satisfaction. Limitations and future research directions are also discussed.

The purpose of this study was to find the risk factors of injury by FMS and to investigate the effects of 12-weeks' combined training program on body imbalance, physical fitness, muscle strength and FMS score in woman rugby players of the national team. Fourteen subjects were woman rugby national players to participate in the 17th Incheon Asian Games. These players tested FMS and performed 12 weeks' (May~Aug, 2014) combined training program (4days, 120min${\geq}$). Statistical evaluation was undertaken using paired t-test (pre vs. post). The results of this study were as follows; Frist, the score of FMS test on Deep Squat, Hurdle Step, Active Straight Leg Raise, and Trunk Stability Push up were significantly increased after 12 weeks' combined training program (p<.05), and also Inline Lunge (p<.01) and Rotary Stability (p<.001) were significantly increased. However, Shoulder Mobility was not significantly increased(p=.104) although the tendency of increased was FMS score. Second, the sum of the entire item was significantly increased after combined training(p<.001). These results suggest that 12-weeks' combined training program has effect of improving FMS score and low-injury risk in woman rugby national players. Therefore, we consider that FMS have effect on prevention of athletic injury and improvement of athletic performance in woman rugby national players.

This study compares the differences of the fit factor by the order of wearing preference between Particulate filtering facepiece respirators(PFFR) and glasses when participants wore simultaneously and a survey of physical and visual complaint. Recognition level about fit of respirators was investigated and the educational (before- and after-) effect of the fit factor. When participants wore PFFR and glasses, physical complaints were nose pressure, slipping, nose and ear pressure, ear pressure and rim loosen, the most highly physical complaints were nose pressure. Visual complaints were demister, blurry vision, dizziness, visual field, and lens dirty, the most highly visual complaints were demister. But, there was significant difference in physical complaint such as nose pressure(10.3%), slipping (23.0%), nose and ear pressure(14.3%), and rim loosen(16.2%), visual complaint such as visual field(13.8%) and lens dirty(32.4%). For the recognition of fit of respirators, respirators fitness, leak site, an initial point and an object, faulty factor, recognition level was higher. Fit factor was increased after education of proper wearing of respirator. Change of the fit factor was smaller compared to the normal breathing and after 6 actions in case of after education. Questionnaire consisted of general characteristics and physical/visual complaint, recognition of fit. Complaints were measured after the QNFT with multiple choices. Quantitative fit factor was measured by device and compared the result of (before- and after-) educational effect. Also, we selected to 6 actions (Normal breathing, Deep breathing, Bending over, Turning head side to side, Moving head up and down, Normal breathing) among 8 actions OSHA QNFT (Quantitative Fit testing) protocol to measure the fit factors. The fit factor was higher after the training (p=0.000). Descriptive statistics, paired t-test, and Wilcoxon analysis were performed to describe the result of questionnaire and fit test. (P=0.05) Therefore, it is necessary to investigate the quantitative research such as training program and glasses fitting factor about the wearing of PFFR and glasses simultaneously.

BACKGROUND/OBJECTIVES: Childhood obesity has become a global epidemic. Development of effective and sustainable programs to promote healthy behaviors from a young age is important. This study developed and tested an intervention program designed to promote healthy eating and physical activity among young children in South Korea by adaptation of the US National Aeronautics and Space Administration (NASA) Mission X (MX) Program. SUBJECTS/METHODS: The intervention program consisted of 4 weeks of fitness and 2 weeks of nutrition education. A sample of 104 subjects completed pre- and post- surveys on the Children's Nutrition Acknowledgement Test (NAT). Parents were asked for their children's characteristics and two 24-hour dietary records, the Nutrition Quotient (NQ) at baseline and a 6-week follow-up. Child weight status was assessed using Korean body mass index (BMI) percentiles. RESULTS: At baseline, 16.4% (boy: 15.4%; girl: 19.2%) of subjects were overweight or obese (based on $BMI{\geq}85%tile$). Fat consumption significantly decreased in normal BMI children ($48.6{\pm}16.8g$ at baseline to $41.9{\pm}18.1g$ after intervention, P < 0.05); total NQ score significantly increased from 66.4 to 67.9 (P < 0.05); total NAT score significantly improved in normal BMI children (74.3 at baseline to 81.9 after the program), children being underweight (from 71.0 to 77.0), and overweight children (77.1 at baseline vs. 88.2 after intervention, P < 0.001). CONCLUSIONS: The 6-week South Korean NASA MX project is feasible and shows favorable changes in eating behaviors and nutritional knowledge among young children.

This study was undertaken with 542 fifth-grade elementary school children to investigate the characteristics in lifestyle, eating habits, food preferences of overweight and obese children in the Pocheon area of Korea. Anthropometry was conducted to determine obesity, and data was obtained on lifestyle, eating habits and food preferences by using questionnaires. The prevalence rate of obesity was 19.5% for boys and 8.5% for girls, and 14.3% of boys and 14.4% of girls were overweight. No significant differences was found in the body size and education years of parents, family income and the empolymental status of mother. Boys did not show any significant difference between subgroups in lifestyle, eating habits and food preferences. Obese girls watched TV longer and liked physical education less than normal and overweight groups, suggesting that an inactive lifestyle can be related to girls' obesity in this study. Overweight girls answered that they had significantly lower preferences for empty-calorie foods such as candies/caramels and cookies as well as high-fat foods such as samgyupsal(pork belly) than normal weight girls, implicating the fear of obesity for overweight girls, although more studies should be done including an assessment of actual intake of these foods. The preferences of obese girls for these foods were not higher than those of normal-weight girls, suggesting that the preference for certain foods may not be the characteristic of obese girls in this study. A special program for nutritional education with a different focus should be developed to combat the problems of each subgroup depending on gender and obesity status to improve the physical fitness of the children in this area.

[Purpose] The OPG/RANK/RANKL signaling is a new family of bone metabolism biomarkers belonging to the immune system. However, the bone metabolism response to long-term exercise in the RANKL/RANK/OPG signaling is less evident. The purpose of this study was to examine these biomarkers in healthy college females after 12-weeks combined exercise intervention. [Methods] Participants (N=22, 22.4±1.3yrs) were randomly divided in two different group: 12 in the control group and 10 in the exercise group performing combined exercise program that interventions was conducted 3 times per week for 12 weeks. The outcome measures included serum concentrations of RANKL, OPG and bone metabolic cytokines such as TNF-α and IL-6, and mRNA expressions of same variables from PBMC. VO_2max and bone mineral density (BMD) were measured at before and after exercise intervention. [Results] There were no significant differences in the serum RANKL, OPG concentrations and all RANKL/RANK/OPG signaling mRNA expression on interaction effect between group and time (NS). Also no significant differences were found in the serum TNF-α and IL-6 concentrations and mRNA expression (NS). The IL-6 mRNA expression only showed significant difference in the main effect of groups (p<.05). There were also no significant differences in the VO_2max and BMD on interaction effect between group and time (NS). [Conclusion] These results suggested that there were no effects on bone mineral density and RANKL/RANK/OPG signaling without the effect of 8-weeks combined exercise on cardiovascular endurance fitness.

The purpose of this research is to investigate the relationship of flow experience on self-esteem and exercise adherence through intention in youth sports club so that youths can continue to exercise. A non-probabilistic sampling method was used as a convenience sampling method with 257 questionnaires being analyzed by frequency, factor analysis, correlation analysis, and multiple regression analysis using the SPSS 21.0 version statistical program for Windows. The results of this study are as follows. First, cognitive flow showed a negative relationship with negative self-esteem, a positive relationship with positive self-esteem, and a positive relationship with tendency and possibility in interrelation. Behavioral flow showed a positive relationship with tendency, possibility, and reinforcement. Second, positive and negative self-esteem showed positive relationships with behavioral flow and did not show any relation. Third, reinforcement showed a positive relationship and tendency and possibility did not affect behavioral flow. It is possible to enhance self-esteem and improve physical fitness through continuous physical activities and to live a lively school life by understanding the immersion experiences of the adolescents' participation in sports clubs and by providing more appropriate physical activity information to adolescents.

The purpose of this study was to examine the effects of the stretching and recreation exercise including health education on physical flexibility and health behavior compliance of women in elderly. Subjects included 28 women elderly who were residents of H Dong, Dondae moon-Gu, Seoul. The treatment intervention was applied during total 8 weeks as 5 times/week for stretching exercise with 2 times/weeks for health education. Data collection were from February to April, 2004. SPSS Window program was used by aims of this study for data analysis. The results were as following: 1. 75 old age above (39.3%) was the most of age in subjects. None education (42.9%) was the most of subjects in this study. Perceived health state was the most as 71.4% in moderate and good health state. 2. Physical flexibility of both shoulder(right z=-4.301, p=,000)(left z=-4.306), both arm(right z=-3.623, p=.0001)(left z=4.111, p=.0001), heel on both ankle(right z=-3.472, p=.0001) (left z=956, p=.0001), both before food(right z=-4.205, p=.0001)left(z=4.191, p=.0001) and both knee(right z=-4.118, p=.0001)(left z=4.082, p=.0001) was increased after 8 weeks more than before stretching and recreation exercise including health education were done. 3. Health behavior compliance(z=-4.073, p=.0001) was significantly on the effect. Therefore, it is confirmed that stretching exercise included health education is an effective nursing intervention for physical, mental, and psychological health management in elderly. Accordingly, authors are proposing that variously effective health management exercise programs must be developed for elderly, at the same time, the application and following up on the programs will be more important in the future.

The purpose of this study is to understand the effect of employees' physical attractiveness in foodservice companies on interpersonal relationship, job satisfaction and organizational citizenship behavior and the moderating effect of gender and company types. Based on total 553 samples obtained from the empirical research, this study reviewed reliability and the fitness of a research model and verified total 3 hypotheses using the Amos program. The hypothesized relationships in the model were tested simultaneously by using a structural equation model(SEM). The proposed model provided an adequate fit to the data, $x^2$(df 179)=627.230, p<0.01, CMIN/DF 3.504, RMR 0.228, GFI 0.903, AGFI 0.875, NFI 0.935, CFI 0.953, RMSEA 0.067. SEM resulted that the employees' physical attractiveness(face attractiveness: $\beta=0.213$; body attractiveness: $\beta=0.111$) showed a significant effect on interpersonal relationship, and interpersonal relationship($\beta=0.375$) had a significant effect on job satisfaction. Also, job satisfaction($\beta=0.756$) had a significant effect on organizational citizenship behavior. As a result of analyzing the moderating role, the effect of the employees' physical attractiveness in foodservice companies on interpersonal relationship, job satisfaction and organizational citizenship behavior was moderated by both of gender and company types. Limitations and future research directions are also discussed.

This study selected 42 domestic preceded literatures that applied exercise programs to the elderly for the past 10 years from 2010 to the first half of 2020 to analyze the characteristics of preceded research, applied period of exercise programs, configuration of exercise programs, and effectiveness of exercise programs on elderly depression, and the conclusion is as follows. First, the majority of the subjects were female and male/female elderly people in the preceding literature, and it appeared that there were no male subjects alone for any of the studies showed. The majority of the ages were over 65 years old, and the number of subjects was 50 or less. In the group, preceded research with exercise/control groups was mostly predominant, and the participated institutions and regions accounted for the majority of the residential area/public institutions and sanatorium. Second, the period of the exercise program was mostly applied for more than 12 weeks, and the frequency of exercise per week was 1-2 times and 3-4 times. Most of the preceding literature was applied with a 60-minute exercise program during the one-time exercise period. Third, most of the contents of the exercise program consisted of a aerobic exercise alone and combination of aerobic·anaerobic exercise. Fourth, it was confirmed that the effects of exercise programs were effective in physical fitness factors as well as in depression and cognitive function.
