The purpose of this study was to analyze the association among high school students' self-efficacy, self-resilience, and oral health promotion lifestyle, identify relevant factors, and provide basic data for oral health promotion programs. The subjects of this study were 287 students, research tool was the structured, anonymous, self-administrated questionnaire. The data were analyzed by SPSSWIN 18.0, Pearson correlation and Hierarchial multiple regression et al. Significant positive correlation was found between self-efficacy and self-resilience and between self-efficacy and oral health promotion lifestyle and positive correlation was also found between self-resilience and oral health promotion lifestyle. Mother's education, past oral health behavior, self-efficacy, and self-resilience affected oral health promotion lifestyle, with the explanatory power of 32.3%. Since self-efficacy and self-resilience are correlated with oral health promotion lifestyle, it is necessary to develop a plan for activating oral health education with the objective of improving the combination of these factors.

The purpose of this study was to investigate the effects of husbands' help on postpartum depression and self-efficacy of mothers, to investigate what to fix of research design and to examine the feasibility of following experimental study. There was no significant difference in the general characteristics of two groups, which consisted 10 pairs of postpartum mothers and husbands, respectively, confirming the homogeneity of between groups. The prevalence of postpartum depression was 45% in the subjects who were measured at 1 week postpartum, and the average performance of the husbands' help in the experimental group was 3.2 out of 4 points. In the Mann-Whitney U Test, the husbands' help lowered the mean rank of postpartum depression in the experimental group(p<.001), and the mean rank of self-efficacy was higher than the control group, but there was no significant difference. In the process of this study, it was confirmed that, on the side of postpartum mothers of control group had burdens of responding to the questionnaire without the benefit of treatment so it is necessary to revise the design of following experimental study.

The purpose of this study is to investigate the effects of job satisfaction and life satisfaction on teacher-children interactions in kindergarten teachers. The tests of Job satisfaction scale, Life Satisfaction scale, Teacher-Children Interactions scale were administered to 320 public and private kindergarten teachers located in Gyeonggi-do, Gangwon-do. The statistical method employed for data analysis was Pearson's correlation analysis and multiple regression analysis. The results of study were as follows. First, the higher factors of job satisfaction (the teaching consciousness, development, innovation, autonomy, fellowship, and reward), the higher the teacher-children interaction. The higher the workload, the lower the verbal interaction between teacher-children. Second, the higher the life satisfaction of kindergarten teachers, the higher the emotional, verbal, and behavioral interaction between teachers and children. Third, the relative influences of the predictors on the overall interaction between teacher and children are life satisfaction (β=.24), development (β=.22), and fellowship (β=.16) and the explained variance are 25%.

This study agrees with the seriousness of the low birth phenomenon in our country and discusses the analysis of the causes of low birth and the establishment of the policy measures for early childhood education and child care in relation to the low birth phenomenon. In particular, the purpose of the policy is to establish a policy plan for up-to-down early childhood education and child care that can be reflected in the policy by members related to early childhood education, breaking away from the existing one for top-down child education and child care. To this end, the research was conducted using Delphi technique and 20 experts in the field of early childhood education and child care were organized into expert panels. In this study, seven policies were proposed for opportunity compliance, eleven policies for service compliance, eight policies for compliance with goods/gift certificates/tax reduction, seven policies for compliance with cash benefits, and five policies for compliance with power. We hope that the bottom-up education and childcare policy measures proposed in this study will provide specific implications and suggestions for resolving the low birth rate.

The purpose of this study was to investigate whether group play therapy is effective in reducing problem behaviors of children with developmental disabilities. The subjects of study were in special schools and 5 children with disabilities using short-term care centers for the disabled, The research period was 12 sessions of 40 minutes twice a week using winter vacation from January 2, 2018 to January 28, The measuring tool, K-CBCL, was used to observe behavioral changes qualitatively. The summary of this study is as follows. First, children with disabilities significantly reduced their aggressiveness, atrophy, depression, and anxiety, and increased their activity during each session. Second, problem behaviors decreased after the intervention of group play therapy, and there were more decreases in internalization problems than externalization problems. The results of this study suggest that group play therapy is meaningful in reducing problem behavior according to the individual characteristics of children with disabilities.

The pilot system for radioactive liquid laundry waste was developed with treatment capacity, 1ton/hr and set up in the Yong Kwang unit #4. The system is composed of tank module, RO systems and a UV/$H_2O$$_2$photo-oxidation unit. The RO system consists of the BW unit (low-pressure RO for brackish water desalination) and the SW unit (high-pressure RO for seawater desalination). The BW unit possesses 4 RO membranes and it can reduce the feed water volume down to 1/10. This concentrated feed water can be reduced again up to 1/10 in its volume in the SW unit composed of 4 RO membranes. The UV/$H_2O$$_2$ photo-oxidation process unit was used for the detergent degradation. The operation of the pilot system was carried out and verified in its capability through the continuous operation and concentration operation using the actual liquid waste from the power plant. The design criteria and data for industrialization were yielded. The efficiency of the UV/$H_2O$$_2$ photo-oxidation process and the optimum operational procedure were evaluated. The decontamination factors for radioactive cobalt and cesium were measured. This on-site test showed the experimental result in the DF$\geq$300 and volume reduction factor$\geq$100.

Transcriptional regulation in response to salt in mutant lines was investigated using oligonucleotide microarrays. In order to characterize the salt-responsive genes in rice, the expression profiles of transcripts that responded to salt-treatment were monitored using the microarrays. In the microarray analysis, among 37,299 reliable genes, 5,101, 2,758 and 2,277 genes were up-regulated by more than 2-fold using the salt treatment, while the numbers of down-regulated genes were 4,619, 3,234, and 1,878 in the WT, ST-495, and ST-532, respectively. From genotype changes induced by gamma ray mutagenesis, 3,345 and 2,397 genes were up-regulated, while 2,745 and 2,075 genes were down-regulated more than 2-fold in the two untreated mutants lines compared with untreated WT, respectively. A total of 3,108 and 2,731 genes were up-regulated more than 2-fold, while 3,987 and 3,660 genes were down-regulated by more than 2-fold in the salt treatment of the two mutants lines compared with the salt treated WT, respectively. The expressions of membrane transporter genes such as OsAKT1, OsKUP, and OsNAC increased more severely in ST-495 and ST-532 than in the WT. The expressions of the proline accumulation related genes such as OsP5CS and OsP5CR were also markedly increased in the salt tolerant mutants when compared to the WT plant.

In this paper, probabilistic flood risk maps were produced for levee break caused by possible flood scenarios. The results of the previous studies were employed for flood stages corresponding to hydrological extreme event quantified uncertainties and then predicted the location of a levee breach. The breach width was estimated by combining empirical equation considered constant width and numerical modeling considered uncertainties on compound geotechnical component. Accordingly, probabilistic breach outflow was computed and probabilistic inundation map was produced by 100 runs of 2D inundation simulation based on reliability analysis. The final probabilistic flood risk map was produced by combining probabilistic inundation map based on flood hazard mapping methodology. The outcomes of the study would be effective in establishing specified emergency actin plan (EAP) and expect to suggest more economical and stable design index.

The purpose of this study is to rethink the common theme that penetrates Faulkner's authorship. That is to say, does his authorship come from "being white"? To answer this question, I try to look into "otherness"/violence against others through re-reading Light in August. By borrowing the idea of "panopticon' mechanism in Michel Foucault's Surveiller et Punir, I will examine the process of justifying the violence against others, especially blacks. Through this process, I try to research the one side of Faulkner's Southern myth which was riddled with the history of pillage and violation of black people's rights. In Light in August, I will compare Jefferson society which encircles Joe Christmas to panopticon mechanism derived from Michel Foucault's Surveiller et Punir. Jefferson society as a designer of surveillance system and an executor as well ceaselessly surveils Joe Christmas's otherness/difference or blackness and tries to punish him whenever they can. With this mechanism, I try to explain that writer's repetitive narration of collective amoral behavior such as lynch comes from his anxiety and conscience about his dark side Southern history.
