This study is to investigate the effect of early childhood teachers' resilience and social support on job stress. The degree of resilience, social support, and job stress was measured for 250 teachers of early childhood education institutions located in City I, and the relationship and relative influence were analyzed. For data processing, correlation analysis and multiple regression analysis were performed using the SPSS 18.0 program. As a result, first, early childhood teachers' resilience and social support were measured at a slightly higher level than average, and job stress at a slightly lower level. Second, the resilience and social support of early childhood teachers had a positive relationship, and the resilience and social support had a negative correlation with job stress. Third, as a result of analyzing the relative influence of early childhood teachers' resilience and social support on job stress, 83% explained that organizational environmental factors, material support, and behavioral factors affect job stress. These results suggest that it is most important to provide resilience and social support that can affect the reduction of job stress of in-service teachers.

The purpose of this study is to evaluate the capacities of repaired structural walls with different shear span ratios(1, 2, 3). Experimental tests were carried out. In this study three isolated large-scale wall specimens were made. The original wall specimens were tested until the drift reaches more than 3%. The region of the damaged specimen with the crack larger than 0.2 mm is replaced by new concrete. Also, severly distorted reinforcements were also replaced by new reinforcements. The crack smaller than 0.2 mm was cured by epoxy resin. Because of the space limitation of the laboratory the dimensions of all walls are the same. The shear-span ratio was controlled by the combination of axial and lateral force using the special test setting. All specimens were tested using the incremental quasi static cyclic load until failure occurs. Test results show that strength of repaired walls was almost equivalent to that of original walls. However, deformation capacities of repaired wall specimens are inferior to the original wall specimens.

We have studied the effects of red ginseng root extract on the derease of MMS-induced gemotoxicity in cultured NIH3T3 cells. The increase in survival and the recovery from DNA synthesis inhibition in MMS-treated cells as a function of normal medium incubation time was potentiated, at a rate higher than those in UV-irradiated cells, by the presence of the ginseng extract. The extract also increased the MMS-induced excision repair as determined by unscheduled DNA synthesis. The amount of MMS-induced DNA single strand breads that are accumulated by polymerase inhibitors was increased, but as a rate lower rate than in UV-induced strand break, by the presence of the extract. These results suggest that the red ginseng extract increase MMS-induced repair and could be used as a reagent for protectiong alkylating agent-induced genotoxicity and cytotoxicity.

In this study, poikilocyte rate and histopathological observation of flounder, Paralichthys olivaceus, treated with formalin, neutral-formalin(0, 50, 100, 150, 200, 300 ppm) at two different temperatures (15 and $25^{\circ}C$) were conducted to determine the time need for recovery. In all test chamber, formalin was more toxic than neutral-formalin and moderate lesions were not observed at low concentration of formalin and neutral-formalin(50~100 ppm). As expectedly, time need for recovery of gill and kidney tissues was lengthening as increasing chemical concentration and temperature. Treatments caused edema, winding of secondary gill lamella, seperation of epithelial layer and thrombosis of secondary gill lamella in the gill; edema, hydropic and hyaline droplet degeneration in the kidney. Representatively, recovery period of fish gill that had been exposed to 300 ppm formalin and neutral-formalin was about 120 and 72 hr($25^{\circ}C$). 72 and 48 hr($15^{\circ}C$). Recovery period of kidney was about 72 and 48 hr($25^{\circ}C$), 48 and 48 hr($15^{\circ}C$) respectively. Maximum value of poikilocyte rate(27.84%) was shown in formalin 300 ppm treated fish at $25^{\circ}C$. Tendency of decreasing poikilocyte rate was similiar to recovery of tissues in treated fish.

Purpose: To evaluate the recovery time of biochemical changes of body after half-course marathon running. Materials and methods: Thirteen amateur half course marathon runners (12 males and 1 females) were studied. Their average age was 44 years old (range: $38{\sim}54$). Biochemical parameters with blood test including AST, ALT, CK-MB, Treponin, BUN, Cr Na, K were evaluated at finish line, 2nd days, 2nd weeks after running. Results: All the biochemical changes were within normal range throughout recovery time, AST reached its maximum level at finish line and continued until 2nd day after running and returned its pre-running level at 2nd week's test. CK-MB reached its maximum level 2nd day after running and recovered at 2nd week's test. Na, K, BUN and Cr reached to the maximum level at finish line, and recovered to pre-running level at 2nd day's test. Conclusion: In case of half-course marathon, the changes of the kidney enzymes due to dehydration were recovered after 2nd day. And the biochemical indicators of muscle fatigue recovered after 2nd week. It needs at least 2 weeks rest after half-course marathon to recover all the biochemical parameter of the body.

Purpose: This study is to investigate factors affecting depression in nursing students. Methods: A survey was conducted with 216 nursing students in college at P city, D city, and K province. Data was collected from April 15 to May 21, 2018, and analyzed by descriptive statistics, t-test, one-way ANOVA and hierarchical regression with IBM SPSS Statistics 24.0. Results: There was a significant positive correlation between verbal violence and depression(r=.261, p<.001), between physical threat and depression(r=.291, p<.001). Also, Self-esteem had a significant positive correlation with resilience(r=.685, p<.001) and negative correlation with depression(r=-.590, p<.001). Moreover, resilience had a significant negative correlation with depression(r=-.612, p<.001). In the hierarchical analysis, factors affecting the nursing students' depression were resilience(${\beta}=-.337$, p<.001), self-esteem(${\beta}=-.279$, p<.001), physical threat(${\beta}=.177$, p=.001). The variable that had the highest impact on depression was resilience and the explanatory power of the regression model was 51.5%(F=17.965, p<.001). Conclusion: The findings of this study indicate that the major factors influencing nursing students depression are physical threat, self-esteem and resilience. Therefore, it suggests that an intervention program will be required to prevent violence during the clinical practice, enhances self-esteem and improves resilience in order to reduce depression of nursing students.

With the recent increasing interest in preventive medicine, observation has been made regarding the positive relationship between a routinized place that includes activity and health improvement. This study evaluates the effective value of a designed landscape for seeing a healing environment and sees the difference of the effective value of classified physical settings regarding Evidence Based Design. Therefore, the study evaluates the perceived restorativeness scale of Cheonggyceheon's 1.5km section and five type settings in the same section regarding how much it works as a healthy urban park. The research methodology used to study sub-settings' and the research site's restoration effects was observation and questionnaires. A PRS (Perceived Restorativeness Scale) questionnaire survey was the research tool employed. The study drew two major results. Firstly, PRS 6.12 is the score of the whole research site, so the study identifies that Cheonggycheon has a mental fatigue restoration function. Secondly, the sub-setting named 'Near Sidewall' was the most attention restorative, according to the ANOVA results. In conclusion, this study suggests significant information support regarding the reasons for creating green areas in urban settings by identifying a particular designed healing sit.
