This study examined the effect and structural relationship of math teachers' teaching ability and class activity types on learners' value perception, confidence, and interest of mathematics at the student level and teacher level. To this end, data from 2nd graders of korea middle school in TIMSS 2019 were applied to the multilevel structural equation model. As a result of the analysis, the teaching ability of math teachers had a positive effect on value perception, confidence, and interest of mathematics at the student level and teacher level. Also, math value perception and math confidence had a positive effect on math interest. and it was confirmed that the teaching ability of math teachers indirectly had a positive effect on math interest by mediating math value perception and math confidence. In addition, the math class activity of applying what was learned to problems had a positive effect on math value perception, but it had a negative effect on math interest. and the class activity of the same ability group had a positive effect on math confidence and math interest. This study presents meaningful implications for math classes in the school field through a multilevel analysis of the student level and the teacher level.

In this study, I examine whether differences in the levels of job satisfaction and turnover intention exist with regard to the police department size. To accomplish this, a way ANOVA analysis of variance(One-way ANOVA) was conducted. As a result, a significant differences were found in job satisfaction and turnover intention according to the department size and grade. Specifically, first, in the job satisfaction level on the department size, the smaller department size was, the lower job satisfaction level was and the bigger department size was, the higher job satisfaction level was. Second, in the turnover intention level on the department size, the result was not statistically significant. Third, in the job satisfaction level on the department grade, the lower department grade was, the higher job satisfaction level was and the higher department grade was, the lower job satisfaction level was. Fourth, in the turnover intention level on the department grade, the lower department grade was, the lower turnover intention level was and the higher department grade was, the higher turnover intention level was.

본 연구에서는 비타민 $B_{2}$ 결핍이 3일간 금식과 6일간 감식시 체내 저장연료 이용에 어떠한 영향을 미치는 가를 알아본 결과, -B2군은 pair-feeding을 감식시켰음에도 불구하고 +B2군에 비해 체중이 유의적으로 낮게 나타났으며 식이 이용효율도 낮았다. 모든 장기, 특히 간장 무게는 -B2군이 +B2군에 비해 무겁게 나타났으며, 감식과 금식시에도 -B2군의 장기무게가 가벼워졌으나 여전히 유의하게 무거웠으며 -B2군의 간장 중성 지방이 높게 나타나 지방간 증상으로 간장이 비대해진 것으로 추정된다. 혈장 포도당과 단백질 함량은 섭식, 금식 및 감식시 +B2군과 -B2군 사이에 유의적인 차이가 없었다. 혈장 중성지방 수준은 +B2군에 비해 -B2군이 섭식시는 높은 수준을 나타냈으나 금식 및 감식시에는 유의적인 차이를 나타내지 않았다. 간장 중성 지방도 이와 유사한 경향을 나타내었다. 혈장 유리지방산 수준은 섭식시에는 +B2군과 -B2군 사이에 유의적인 차이가 없었으나, 금식으로 인해 +B2군은 유리지방산 수준이 증가하였고 -B2군은 오히려 감소하여 -B2군이 +B2군 보다 낮게 나타났다. 그러므로 비타민 $B_{2}$ 결핍으로 인해 이 유리지방산의 유리가 원활히 일어나지 않았거나, 비타민 $B_{2}$ 결핍으로 인해 지방산화가 저해된 것이 금식으로 지방이 에저지원으로 이용되어야만 하는 상황이 발생하여 감소된 지방산 산화가 다소 회복된 것으로 추정된다. 금식 및 감식시 +B2군에 비해 -B2군이 근육단백질 수준은 높은 경향을 나타내었고 근육 글리코겐 수준은 낮은 경향을 나타내어 -B2군이 심각한 비타민 $B_{2}$ 결핍으로 저지방이나 근육단백질을 이용하지 못하게 됨에 따라 근육 글리코겐을 이용한 것으로 추정된다. 이는 +B2군에 비해 -B2군의 뇨중 총질소 배설량이 적은 것으로도 재확인되었다. 그러므로 금식이나 감식시 체지방이나 체단백질을 이용하는 에너지 보충 적응기전이 일어나야 하나 비타민 $B_{2}$ 결핍상태에서는 이러한 체내 열량공급이 지장을 받게 되며, 체단백질 이용저하로 포도당 신생이 영향을 받아 장기간의 금식 또는 감식시에는 혈장 포도당 수준도 낮아질 것으로 예상된다.

This study aims to identify factors to affect cancer screening utilization and differences in cancer screening by household income. This research selected 3,393 adults aged ${\geq}40years$ among surveyees from the 6th(2014) Korea National Health and Nutrition Examination Survey. We analyzed state of cancer screening utilization according to general characteristics, life style, health status, income level using descriptive statistics. Logistic regression analysis was used to examine the factors associated with cancer screening utilization. In result, cancer screening rate was significantly different according to household income. And the significant factors associated with cancer screening utilization were sex, age, marital status, education level, economic activity, private insurance, smoking, presence or absence of high physical activity, number of chronic diseases, and household income. This indicates that the effective cancer screening program on the low household income, chronic disease patients is needed, suitable for digital age. We believe that these results will be used positively for the equity of cancer screening utilization, providing the basic materials for the further research on the establishment of the health-related policy.

This study was performed to investigate the effect of protein intake on kidney development and function in growing rats. Fourty-two male Spraque-Dawley rats of weighing $97.5\pm1.9g$ were divided into 3 groups and given 5%, 15% or 50% casein diets for 6 weeks. Body weight gain was higher in the 50% group. The kidney weight was selectively affected more by the level of dietary protein compared to the other organs. DNA and RNA content were significantly higher in the 15% and 50% groups than in the 5% group but the differences disappeared when DNA and RNA were expressed per g of kidney weight. Protein and protein/g kidney content were increased with increasing level of protein in diet. GFR/animal and GFR/100gB. W. were significantly higher in the 50% group compared to the 5% and 15% groups. There was no differences in PAH clearence and RBF. Osmolality was not affected by dietary protein level. BUN and urinary nitrogen excretion were increased with the increasing dietary protein level. Although urinary Ca excretion was not significantly difference among 3 groups, the rats in the 5% group showed 30% less Ca excretion compared to the other groups. Above results suggest that dietary protein level has a great effect on the kidney weight and GFR in growing rats. Especially the hyperfiltration inhanced by high protein diet may accelerate the kidney senescence.

In this study, we examined at what level young people perceive their level of life and the overall degree of happiness in their lives, and empirically analyzed the factors affecting them through multiple regression and ordered logit models. As a result of the analysis, young people were more aware of the degree of overall happiness than their perception of their lives. It has been confirmed that the factors affecting the young generation's perception of the level of life and the degree of happiness are different and different factors are working on each group. In addition, it has been found that the subjective factors of psychological and emotional characteristics have a greater influence than the objective factors of social and demographic characteristics at the level of awareness of life and happiness level. However, in the case of the youth group, it was found that objective factors such as job satisfaction are the determinants that have the greatest influence on life awareness and happiness. The tendency to paradoxically respond to the current level of happiness due to despair of the future has been found to be seen in some subgroups(middle income plus working group) rather than in the whole youth generation.

This study aimed to investigate depression, fatigue, and role-overload in nurses caring for COVID-19 patients and identify factors affecting depression. Data were collected from 142 nurses caring for COVID-19 patients at four designated COVID-19 hospitals using self-report questionnaires, from September 8, 2020, to September 17, 2020. The subjects' scores for depression, fatigue, and role-overload were 14.51±9.54, 3.19±0.64, and 3.30±0.64 points, respectively. Depression was positively correlated with fatigue (r=.40, p<.001) and role-overload (r=.30, p<.001), and fatigue was positively correlated with role-overload (r=.54, p<.001). Factors affecting depression included fatigue (β=.23, p=.014), health status (moderate: β=.28, p=.001; unhealthy: β=.26, p=.002), and hospital type (university hospital: β=.18, p=.024). The explanatory power (R²) of the model was 28.1%. In order to manage the nurse's depression level, a strategy for lowering the fatigue level and a strategy for improving the nurse's health statue are needed.

The purpose of study is to measure nurses' empathy levels and to examine the effects of their empathy levels on their life and job satisfaction. The questionnaire was administrated to 150 nurses working in hospitals in Busan. The questionnaire consists of three factors : empathy level, life satisfaction, and job satisfaction. Nurses are classed into two : shift work nurse and non-shift work nurse by their work type. 144 out of 150 questionnaires were used for the analysis with IBM SPSS Statistics 21. The shift work nurses with higher empathy levels showed higher job satisfaction. The non-shift work nurses with higher empathy level revealed higher life satisfaction. Interestingly, while empathy level had positive effects on shift work nurses' job satisfaction(${\beta}=.282$, p=.006), it also had impact on non-shift work nurses' life satisfaction positively(${\beta}=.252$, p=.048). As results show, nurses' life and job satisfaction were positively related to their empathy levels. Given the fact that lack of nurses' empathy often lead to conflicts with patients, in order to improve nurses' job performance, we need a new perspective of understanding the important role of empathy in nurses' job satisfaction and life satisfaction.
