The objective of this study was to investigate how to improve job satisfaction for dietitians and nutrition teachers by identifying influencing factors in Daejeon and Chungnam Province, South Korea. A survey was conducted among school foodservice dietitians and nutrition teachers from selected primary, middle and high school in the area. This survey consisted of general characteristics, status of their job, job satisfaction, work satisfaction and work performance. In this study we found current state of general characteristics and status of their job according to frequency analysis and the level of work satisfaction, work performance and job satisfaction using descriptive statistics. The t-test, ANOVA and Duncan-test were also conducted in order to searching for tendency of job satisfaction according to the general characteristics and the status of their job. Pearson's correlation was carried out in order to find correlation with job satisfaction. Also, factors, which influenced job satisfaction according to regression analysis, were drawn. We describe the difference of job satisfaction between irregular dietitians and nutrition teachers as well. Besides we discussed the improvement of dietitians' (nutrition teachers') work environment to raise their job satisfaction through this study.

Objectives: We aimed to examine health-related nutritional knowledge and dietary behavior related to caffeine intake among high school students (n = 310) in the Yongin region of Korea. Methods: Data were collected using a face-to-face survey, and analyzed using chi-square test, t- test, and logistic regression analysis. Results: The level of caffeine intake in respondents was divided into low (< 30 mg/d; n = 208) and high caffeine intake groups (> 30 mg/d; n = 102). Total nutritional knowledge related to bone disease was higher in the low intake group (score 2.75) than the high intake group (score 2.39; p < 0.05). The high intake group had lower scores for nutritional knowledge (score 0.70; p < 0.05) related to how caffeinated beverages affect sleep and for dietary behavior (score 3.25; p < 0.001), based on "I avoid caffeinated foods before sleep," than the low intake group (nutritional knowledge score, 0.80; dietary behavior score, 3.76). Conclusion: In the overall analysis, the low caffeine intake group had better nutritional knowledge related to bone and sleep health, and healthier dietary behavior related to sleep health compared with the high intake group.

Purpose : This study aimed to identify the moderating and mediating effects of resilience on the relationship between role conflict and job satisfaction among nurses working in a comprehensive nursing care service ward. Methods : Participants were 130 comprehensive nursing care service ward nurses from four hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and hierarchical multiple regression analysis, using SPSS 25.0. The mediating effect of resilience on the relationship between role conflict and job satisfaction was analyzed using multiple regression analysis according to Baron and Kenny's procedure. Results : Statistically significant negative correlations were found between role conflict and resilience (r=-.25, p<.007) and between role conflict and job satisfaction (r=-.38, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.54, p<.001). A partial mediating effect of resilience was found between role conflict and job satisfaction (Z=-2.53, p=.012) but no moderating effect was found. Conclusion : To improve the job satisfaction of comprehensive nursing care service ward nurses, interventions for alleviating role conflict and improving resilience as well as evaluations of the two variables are necessary.

Purpose: Myofascial syndrome is a chronic muscle pain caused by repetitive motions with stress-related muscle tension. This study aimed to investigate the validity and reliability of the evidence for diagnosing myofascial pain syndrome in trapezius muscle using a pressure algometer and surface electromyography. Methods: The experiments were performed using a total of 10 subjects, and the target locations were determined by means of a pressure algometer in the right upper trapezius muscle. The part with the lowest pain value as the trigger point and the part with the highest pain value as the non-pain trigger point were selected for measuring the locations. The median frequency and average frequency were measured in those locations with electromyography. To check the muscle fatigue, the upper trapezius muscle was moved up and down for 2 seconds at 5-second intervals in 30 seconds. The measured values were evaluated using the independent paired t-test and MannWhitney U-test. Results: The median frequency at the non-trigger point (13.7) was significantly higher than that at the trigger point (7.3). Furthermore, the mean frequency (14.7) at the non-trigger point was significantly higher than that at the trigger point (6.3). Conclusion: The results showed the correlations between the trigger points of the muscle pain and frequency analysis of surface electromyography. Thus, this study may be possible to use as a diagnostic tool for myofascial pain syndrome.

This paper presents experimental and numerical investigations of aluminum tubular members subjected to combined bending and web crippling. A series of tests was performed on square hollow sections (SHS) fabricated by extrusion using 6061-T6 heat-treated aluminum alloy. Different specimen lengths were tested to obtain the interaction relationship between moment and concentrated load. The non-linear finite element models were developed and verified against the experimental results obtained in this study and test data from existing literature for aluminum tubular sections subjected to pure bending, pure web crippling, and combined bending and web crippling. Geometric and material non-linearities were included in the finite element models. The finite element models closely predicted the strengths and failure modes of the tested specimens. Hence, the models were used for an extensive parametric study of cross-section geometries, and the web slenderness values ranged from 6.0 to 86.2. The combined bending and web crippling test results and strengths predicted from the finite element analysis were compared with the design strengths obtained using the current American Specification, Australian/New Zealand Standard and European Code for aluminum structures. The findings suggest that the current specifications are either quite conservative or unconservative for aluminum square hollow sections subjected to combined bending and web crippling. Hence, a bending and web crippling interaction equation for aluminum square hollow section specimens is proposed in this paper.
