The purpose of this study was to obtain data on the contribution of job characteristics (work, autonomy, reward, community, fairness, value) towards job burnout (emotional exhaustion, cynicism), job engagement (vigor, dedication, absorption) and turnover intention in school foodservice employees. Typically, 594 school foodservice employees in the Busan area participated in our survey. Workload (${\beta}=-0.512$, p<0.001) had the highest negative influence on emotional exhaustion, whereas reward (${\beta}=-0.216$, p<0.001) and community (${\beta}=-0.214$, p<0.001) had the highest negative influence on cynicism. Community (${\beta}=0.305$, p<0.001) and workload p<0.001) had the highest positive influence on vigor. Community (${\beta}=0.261$, p<0.001) and (${\beta}=0.238$, p<0.001) had the highest positive influence on dedication. (${\beta}=0.287$, p<0.001) and community (${\beta}=0.224$, p<0.001) had the highest positive influence on absorption. Workload (${\beta}=-0.195$, p<0.001) and community (${\beta}=-0.182$, p<0.001) had the highest negative influence on turnover intention. Overall, the results show that job characteristics are very important factors affecting foodservice employee's burnout, engagement, and turnover intention. So should try to reduce the employees' workload and increase the rewards for them along with activating communication among each other.

The purpose of this study was to obtain data to improve customer orientation by managing emotional labor in foodservice employees. This study investigated the correlation between emotional labor (surface acting, deep acting), job burnout (emotional exhaustion, cynicism), and job engagement (vigor, dedication, absorption) in high school foodservice employees, and how they affect customer orientation. Our survey was administered to 330 school foodservice employees in the Busan area from June 2 to June 27, 2015. A total of 321 questionnaires were used for final analysis. The mean values for deep acting (p<0.01), cynicism (p<0.01), and dedication (p<0.05) significantly according to the position of the emproyees. The mean customer orientation significantly according to employment status (p<0.01) and meal service time (p<0.01). There was positive correlation (p<0.01) between surface acting, and emotional exhaustion cynicism, but negative correlation (p<0.01) between surface acting and vigor, dedication, absorption, and customer orientation. Deep acting had negative correlation (p<0.01) with emotional exhaustion and cynicism, positive correlation (p<0.05) with vigor, dedication, absorption, and customer orientation. Surface acting had negative influences on emotional exhaustion and cynicism, cynicism had negative influences on vigor, dedication, absorption, and customer orientation. Deep acting had positive influences on absorption and customer orientation, absorption had positive influences on customer orientation. Thus, nutrition teacher(dietitian) should educate foodservice employees the positive effects of deep acting to change their surface acting to deep acting, while actively managing internal customers.

The purposes of the study were to assess levels of burnout, engagement, and turnover intention of dietitians and chefs and to investigate the relationships among the antecedents and consequences of burnout and engagement. A total of 257 dietitians and chefs at a contract foodservice management company in Korea were surveyed using a self-administered questionnaire. Burnout (exhaustion, cynicism, and professional efficacy) and engagement (vigor, dedication, and absorption) were measured with three dimensions each. The dietitians showed significantly higher exhaustion (p < .05) and significantly lower vigor and dedication than the chefs (ps < .05). The exhaustion and cynicism dimensions of burnout were negatively correlated with all three dimensions of engagement (ps < .001) and positively correlated with turnover intention (ps < .001). The professional efficacy was positively correlated with all three engagement dimensions (ps < .001), but not with turnover intent. In addition, turnover intention was positively correlated with negative affectivity and work-load and negatively correlated with vigor, dedication, and absorption. A series of hierarchical regression analyses were conducted to assess the effects of the personal (positive and negative affectivity) and situational factors (workload, interpersonal conflict) and job stresses on turnover intention. After removing the effects of the personal and situational factors, cynicism (p < .01) was the only significant predictor of turnover intention. Based on the findings, suggestions for recruiting and retaining qualified and motivated employees were provided.

The purpose of this study was to provide basic information to school foodservice employees so that they can meet their professional responsibilities by understanding the relationship of job burnout, job engagement, job stress and level of job satisfaction and analyze the influence between these factors according to the general characteristics of the employees. The subjects included employees at 426 school foodservices in Busan. The mean job engagement was significantly different in the reason that cooks chose this profession(p<0.05), and readiness to quit(p<0.001). The mean job stress was significantly different in different age groups(p<0.01), cooking certification(p<0.01), reason that cooks chose this profession(p<0.01), and readiness to quit(p<0.05). The mean job stress was significantly different in the reason cooks chose this profession(p<0.01), and readiness to quit(p<0.05). In terms of the level of satisfaction of coworkers, the subfactor of job burnout, 'self-confidence' and 'achievement' had positive influences (p<0.01) and for the level of satisfaction of the work, it had positive influences on 'achievement'(p<0.01) and negative influences on 'exhaustion' (p<0.01). In terms of the level of satisfaction of co-workers and work, the subfactor of job engagement, 'absorption' had positive influences(p<0.01). Among the level of job satisfaction, for the level of satisfaction of pay, the subfactor of job stress, 'unstable job' had negative influences(p<0.01) and 'role conflict' had positive influences(p<0.05). For the level of satisfaction of co-workers, the subfactor of job stress, 'role conflict' had negative influences(p<0.01), and for the level of satisfaction of work, 'inappropriate circumstance' and 'unstable job' had negative influences (p<0.01).

We studied the interaction of 4',6-diamidino-2-phenylindole (DAPI) with single stranded poly(dA) using optical spectroscopic methods, including absorption, circular dichroism (CD), and fluorescence spectroscopy. The temperature-dependent conformation of poly(dA) was also investigated. The conformation of poly(dA) varied with temperature, which is explained by the stacking-destacking process of the adenine bases, resulting from the sugar conformation. The hypochromicity and red-shift in the absorption spectroscopy, the lack of CD change in the drag absorption region, and the fluorescence behavior, especially a great accessibility of the I2 quencher to the poly(dA)-bound DAPI, suggest that DAPI binds to the outside of poly(dA). The Job plot for the DAPI-poly(dA) mixture demonstrated that a stoichiometry of one DAPI molecule binds to the one phosphate of poly(dA).

This study examined the influence of job stress and personal resources (hardiness, optimism) of child counselors on their burnout and work engagement. For the study, 171 child counselors were surveyed. The main effects of job stress and personal resources on burnout and engagement were tested using hierarchical multiple regression analysis. The findings of this study were as follows: First, the study showed that both job stress and personal resources were related to burnout and work engagement. Specially, job stress was more closely related to burnout, whereas personal resources were more closely related to work engagement. Second, hardiness as personal resources reduced the level of burnout in child counseling. Third, although job stress negatively affected the level of work engagement, personal resources (hardiness, optimism) were relevant predictors of work engagement. Hardy and optimistic child counselors are less likely to experience burnout, they are more likely to experience vigor, dedication, and absorption on their job. Based on the results of this study, the practical implications for child counselors were discussed.

The effects of particle sizes (small, medium and large sizes) and gelatinization treatment on the changes of the instant properties of Job's tears powder were investigated. The degree of gelatinization on the different particle size samples of Job's tears powder was the highest in the small particle size, and it also showed an increasing trend regardless of pregelatinizing whether it is or not as the particle size decreased from large particle size to small particle size. The water solubility index of the pregelatinized samples was high compared to that of ungelatinized samples regardless of particle size and temperatures. The water absorption and swelling power increased as particle size and temperature were increased. The dispersibility and sinkability of ungelatinized sample was increased as particle size and temperature were increased and it also showed lower value regardless of particle size and temperature. However, the dispersibility and sinkability of pregelatinized samples were shown to have the opposite result, such that the smallest particle size of pregelatinized sample had the lowest sinkability (11.3%). The turbidity of the pregelatinized small particle size was the highest by a factor of 1.08.

For the development of a new antidementia functional food or alternative drug using agricultural products, Job's tears (Coix lachrymajobi L.), which shows high acetylcholinesterase (AChE) inhibitory activity (55.1%) was selected and the extraction conditions of AChE inhibitor were optimized. AChE inhibitor of Job's tears was maximally extracted when it was treated with 60% methanol at $40^{\circ}C$ for 6 h. The AChE inhibitor of the methanol extracts was partially purified by systematic solvent extraction, thin layer chromatography, silica gel chromatography and reverse-phase HPLC and the partial purified AChE inhibitor with inhibitory activity ($IC_{50}$) of $0.608\;{\mu}g$ was obtained. The partial purified AChE inhibitor was soluble in methanol and hexane, and insoluble in water. Its maximum absorption spectra was 230 nm and also it was stable in the range of $30^{\circ}C$ and $70^{\circ}C$ and pH 4.0-8.0 for 1 h.
