Purpose: The purpose of this study was to investigate the effects of firefighters' job stress and emotional labor on their turnover intention, and analyze the main factors impacting turnover intention in this context. Methods: Based on a descriptive survey study design, we administered a structured questionnaire among 231 firefighters at one fire station in G metropolitan city from November 13 to 27, 2020. Results: Regarding job stress, participants showed differences based on marital status (p<.05), health status (p<.001), total service period (p<.05), and assignment (p<.05). For emotional labor, a significantly higher rate was observed for female than male firefighters (p<.05), with differences also observed in age (p<.001), health status (p<.001), total service period (p<.05), rank (p<.001), and assignment (p<.05). Further, for turnover intention, significant differences were noted with respect to age (p<.001), education (p<.01), health status (p<.001), total service period (p<.01), work unit (p<.05), rank (p<.001), and assignment (p<.05). A significant correlation was found between job stress and emotional labor and turnover intention. Regarding the factors affecting turnover intention, significant differences were noted based on education, rank, job stress, and emotional labor; the explanatory power was 53.9% (F=13.806, p<.001). Conclusion: Tailored support programs must be developed to ease firefighters' job stress and reduce their emotional labor to facilitate effective manpower management and reduce firefighters' turnover intention.

This study investigated differences in nutritional knowledge and eating habits of adolescents living in rural and urban areas of Inner Mongolia, China. A survey was conducted on 869 middle school students in Hohhot, Inner Mongolia: 436 from urban and 433 from rural school. Subjects answered a questionnaire about socio-economic characteristics such as parents' education level and family affluence scale, nutritional knowledge, needs for nutritional education and food habits. Levels of parents' education (p<0.001) and family affluence (p<0.001) were significantly higher in urban students. Nutritional knowledge level of urban students was higher than that of their counterparts (p<0.001). However, rural students reported higher needs for nutritional education (p<0.001). Rural students more frequently consumed snacks (p<0.001) and instant noodles (p<0.001) than urban students. However, consumption frequencies of lunch (p<0.001), dinner (p<0.001), fast food (p<0.001), fruits (p<0.001), vegetables (p<0.001), and milk (p<0.001) were higher in urban students. Considering differences in eating patterns between urban and rural students in Inner Mongolia, appropriate nutritional education programs and nutritional policies should be established for rural students to promote a healthy diet.

The purpose of this study was to investigate the effects of family cohesion and self-care agency on the quality of life in community-dwelling elderly. Using a descriptive survey design, data were collected during September 2-20, 2016 by distributing questionnaires to and retrieving them from 197 elderly participants aged 65 years or older in two senior welfare centers located in "B" metropolitan city. Results showed that family cohesion of community-dwelling elderly was significantly positively correlated with their self-care agency (r=.434, p<.001) and quality of life (r=.544, p<.001), while self-care agency was significantly positively correlated with quality of life (r=.571, p<.001). The factors that had the biggest effect on the quality of life in community-dwelling elderly were identified in the order of self-care agency (${\beta}=0.413$, p<.001) and family cohesiveness (${\beta}=0.365$, p<.001). These variables were found to have an explanatory power of 42.8% for quality of life (F=74.31, p<.001). Therefore, a strategy to improve self-care agency and family cohesion may be helpful in improving the quality of life in community-dwelling elderly.

Purpose: This study examines the health behavior and health-related quality of life (HRQOL) among married men and women, utilizing data from the Korean National Health and Nutritional Examination Survey, encompassing 4,217 subjects. Methods: A multiple regression model was employed to analyze the data. Results: Married men demonstrated a significantly good relationship between HRQOL and perceived health state (β=.32, p<.001), while married women showed a similar relationship with perceived health state (β=.38, p<.001). Additionally, married men demonstrated significantly neutral relationship between HRQOL and perceived health state (β=.30, p<.001), as did the married women (β=.38, p<.001). Both married men (β=-.11, p<.001) and married women (β=-.08, p<.001) were found to experience depression. oreover, the HRQOL in married men was positively associated with private health insurance (β=.08, p=.001), and the same trend was observed in married women (β=.10, p<.001). Married men with unmet medical needs showed a negative association with HRQOL (β=-.08, p<.001), and married women with unmet medical needs showed a similar negative association (β=-.12, p<.001). Furthermore, outpatient medical use(2 weeks) was negatively associated with HRQOL in both married men (β=-.07, p=.001) and married women (β=-.07, p<.001). Moreover, married women displayed a significant negative association between HRQOL and the prevalence of obesity(β=-.04, p=.048) and stress (β=-.05, p=.009) and a positive association with aerobic exercise (β=.04, p=.027). Conclusions: This study suggests that health behavior significantly influences the HRQOL among married men and women. The findings of this study can guide policymakers in developing strategies to improve health behavior and HRQOL within households.

Purpose: This study aims to present a database for the development of a healthcare management program based on the survey and analysis of self reported psychosomatic symptoms among the current dental technology students. Methods: Subjects of our study are 480 dental technology major students enrolled in a third year college located Gyeonggi, Chungcheong, and Gangwon province. Using a random sampling, we conducted a self-report survey from August 30, 2011 to October 28, 2011 and 418 reports were collected as feedback and we put an analysis on them. Results: 1. The average physical self symptom was 20.49, which is higher than the average mental self symptom(18.54). Of the subcategories of psychosomatic self symptom, we observed multiple subjective symptoms as the highest one(37.77), and aggression as the lowest(13.77). 2. As to gender, both physical and mental self symptom were statistically significant with the scale score of(p<.001). The scale score of subcategories is as follows; multiple subjective symptoms(I, p<.001), eye and skin(B, p<.001), digestive(C, p<.001), impulsiveness(H, p<.001), lie scale(L, p<.001), mental instability(J, p<.001), depression(K, p<.001), aggression(F, p<.001), irregularity of life(G, p<.001), mouth and anal(D, p<.05), nervousness(E, p<.05). 3. As for obesity, statistical significance was shown with the scale scores of physical self symptom(p<.001), multiple subjective symptoms(I, p<.001), digestive(C, p<.001), aggression(F, p<.001), depression(K, p<.01), irregularity of life(G, p<.01), respiratory(A, p<.05), eye and skin(B, p<.05), impulsiveness(H, p<.05), mental instability(J, p<.05). The scale scores in the environmental quality and life satisfaction were shown as follows; depression(K, p<.001), lie scale(L, p<.01), and irregularity of life(G, p<.05). 4. We employed multiple regression analysis to take account of general factors affecting psychosomatic self symptoms, and drew that the explanatory power of the model was proved with the scales of physical self symptom(4.1%) and mental self-symptom(3.6%). Obesity was a factor that affects physical self symptom with the scale score of(p<.01), and environmental quality and life satisfaction(p<.01) and obesity(p<.05) affect mental self symptom. Conclusion: In this analysis we observed obesity of dental technology students can influence their psychosomatic self symptoms. In this sense, it would be reasonable to develop a healthcare management and education programs that help the students maintain a healthy weight and promote their health.

The purpose of this study was to investigate tangible clues influence on perceived risk and overall satisfaction of customers at family restaurant in South Korea. In this research overall CFA and SEM were employed to analyze the data. Tangible clues were divided to 3 factors and perceived risk to 6 factors. Tangible clue 1 'physical evidence', had negative(-) influence on financial risk(p<0.01), performance risk(p<0.01) and psychological risk(p<0.001). Tangible clue 2 'employee' affected negatively(-) time risk(p<0.001), performance risk(p<0.001), psychological risk(p<0.01) and social risk(p<0.001). And tangible clue 3 'service process' influenced negatively(-) physical risk(p<0.01), time risk(p<0.05), financial risk (p<0.001) and performance risk(p<0.01). And among customer's perceived risks, 3 factors(time risk~p<0.001, performance risk~p<0.001, social risk~p<0.001) influenced negatively(-) their overall satisfaction. Through these results, it appears that customers perceive various tangible clues and risks at family restaurants. And they are likely to satisfy or dissatisfy according to their perceived risks. As a result, food service companies need to research various customers' perceived risks as important marketing strategy, and reduce them for increase and induction of customers' satisfaction.
