The purpose of this study was to analyze the effect of perceived parental neglect and abuse and peer attachment on school life adjustment according to children's gender. A total of 2,264 5th graders from the second Korea Child-Adolescent Panel Survey participated. The results were as follows: First, the boys had higher parental neglect and abuse scores than the girls, while the girls had higher peer attachment scores and higher school life adjustment scores than the boys. Second, every sub-element of school life adjustment was significantly negatively correlated with parental neglect and abuse regardless of the children's gender. Every sub-element of school life adjustment was significantly positively correlated with the 'communication' and 'trust' sub-elements of peer attachment regardless of the children's gender. In the case of the boys, the 'study activity' and 'peer relation' sub-elements of school life adjustment were significantly negatively correlated with the 'alienation' sub-element of peer attachment. For the girls, every sub-element of school life adjustment was significantly negatively correlated with the alienation sub-element of peer attachment. Finally, the factors of 'parental neglect and abuse', and the peer attachment sub-elements of 'communication', and 'trust' significantly predicted the boys' school life adjustment, while for girls, the significant predictors were 'parental neglect and abuse', 'communication', 'trust', and 'alienation'.

The gluten protein content in whole-wheat flour is low, which affects the elasticity and viscosity of the dough. Enzymatic modification of the protein may result in a network that mimics gluten, which plays an important role in the processing of whole-wheat foods. In this study, the effects of Halomonas alkaliantartica laccase (LacHa) on the quality parameters of whole-wheat bread were investigated. The optimum dosage of LacHa was 4 U/100 g of whole-wheat flour. At this dosage, whole-wheat bread exhibited the best specific volume and optimum texture parameters. Laccase also extended the storage duration of whole-wheat bread. We analyzed the micro-structure of the dough to determine its gluten-free protein extractable rate and free sulfhydryl group content, and verify that LacHa mediates cross-linking of gluten-free proteins. The results demonstrated that the cross-linking of gluten-free protein by LacHa improves the texture of whole-wheat bread. As a flour improver, LacHa has great developmental and application potential in baked-food production.

The purpose of this study was to describe and analyze teachers' happy school life from teachers' perspectives. For this purpose, interviews with teachers and administrators were analyzed to describe and interpret the meaning of teachers' happy school life. The result indicated that teachers' happy school life could be understood with teachers' professional instruction, rational communication among members, understanding for meaning of works.

The effect of preadaptation at low temperature on cryoprotection was studied for Lactobacillus paraplantarum C7, a bacteriocin producer isolated from kimchi. L paraplantarum C7 cells in their log growth phase were incubated at $15^\circ{C}$, $10^\circ{C}$, or $5^\circ{C}$ for 2, 4, and 6 h, respectively, before being frozen at $-70^\circ{C}$. After 24 h of freezing, viable cells were counted after brief thawing. The freezing-thawing cycles were repeated three more times. Cells preadapted at $10^\circ{C}$ or $5^\circ{C}$ before freezing survived better than control cells, but preadaptation at $15^\circ{C}$ did not confer cryoprotection. Chloramphenicol addition did not destroy the cryoprotection, indicating that protein synthesis was not required for the development of cryoprotection. SDS-PAGE showed induction of a 6.5-kDa protein, a major cold-shock protein, in preadapted cells.

This study aims to examine the effects of high school students' time management behaviors on their satisfaction with educational consumption and school life. Three hundred seventy-six high school students in Seoul participated in this investigation. The SPSS ver. 19.0 program was adopted for the descriptive analysis, factor analysis, Cronbach's ${\alpha}$, and multiple regression analysis. The results of the present study can be summarized as follows: first, the levels of time management behavior, satisfaction with educational consumption at school, and satisfaction with school life were relatively high. Second, an analysis of the relative influence on satisfaction with educational consumption revealed that the students' time management behavior was the most influential factor, followed by academic achievement. As the levels of time management behavior and academic achievement were high, the level of satisfaction with educational consumption was high. Finally, an analysis of the relative influence of satisfaction with school life also revealed that the students' time management behavior was the most influential factor, followed by academic achievement. Based on the findings, that is, the effects of high school students' time management behavior and other involved variables on their satisfaction with educational consumption and school life, a future study can present specific ways to enhance the level of satisfaction with educational consumption and school life.

This research is focused on the influence of internalization problem and attachment to parents on the adjustment to school life, as well as on the attachment to parents as moderators in the influence of the process of internalization problem on the adjustment to school life. To verify the hypothesis, a survey research method was applied using stratified cluster sampling method, and focusing on middle school students in Seoul. Eleven schools were selected randomly from each of the eleven District Offices of Education in Seoul, and data were collected from 1,200 students. The data were analyzed by using the T-test and hierarchical regression methods, and the results are as follows. First, the internalization problem has negatively affected the adjustment to school life. Secondly, the moderators of the attachment to parents in the adjustment to school life were investigated. Through the above mentioned analysis, it can be deducted that, intervention with internalization problem is required in order to promote the adjustment to school life, and the importance of the attachment to parents should be addressed in the intervention for improving adjustment to school life.

Objectives: The purpose of this study was to identify relationships between experiential activity, ego-resilience, sense of community, and school life adjustment of middle school students and to provide the basic data that can contribute to the activation of experiential activities. Methods: 2,351 middle school students of panel survey conducted by National Youth Policy Institute were used in the final analysis. The structural equation model(SEM) was carried out to analyze structural relationships between experiential activity and ego-resilience, sense of community, and school life adjustment of the youth. IBM SPSS Statistics 20.0 and IBM SPSS AMOS 20.0. were used for the analysis of all data. Results: Experiential activities had a statistically significant positive effect on ego-resilience(p<0.001), school life adjustment(p<0.05), and the sense of community (p<0.001). Especially experiential activities acted on ego-resiliency, a sense of community, school life adjustment as an important parameter. Sense of community also showed to be an important mediating role between ego-resiliency and school life adjustment. Conclusions: In order to maximize the effectiveness of experiential activities, it is necessary to build the community networking enough to take full advantage of community resources and develop various experiential activities to meet the needs of youth and social change.
