Objective: This study examined the influence of maternal attachment on adjustment in adolescence and investigated whether paternal attachment had any moderating effects on the relationship between maternal attachment and adjustment in adolescence. Methods: The participants of this study were 300 second graders from two middle schools in Seoul. We measured paternal and maternal attachment as perceived by the participants, adjustment in adolescence through school life adjustment, depression, and relational aggression. The study applied correlation analysis and hierarchical regression analysis suggested by Baron and Kenny (1986). Results: First, participants with high parental attachment showed high levels of school life adjustment, low level of depression, and low levels of relational aggression, demonstrating healthy psycho-social adjustment in adolescence. Second, paternal attachment played a facilitating role in the process of high maternal attachment's positive influence on school life adjustment. Third, paternal attachment mitigated the process of low maternal attachment's negative influence on depression. Conclusion: Our findings highlight the importance of emotional communication, support, and intimacy between parents and children in middle school. Furthermore, it emphasized the importance of the paternal role and involvement in the mother-child relationship.

Introduction: Quality of life (QoL) issues are of importance in relatives of women with breast cancer (BC)as caregivers in neglecting their own needs due to care of a patient and also as women regarding the potential risk of themselves developing BC. The objectives in the present study were to compare the QoL of female relatives of women in treatment for breast cancer. To date, no study had examined multi-dimensional QoL in accompanying people as compared them into two groups of female relatives whose first degree and second degree. Methods: QoL of female relatives was assessed using the Quality of Life-Family Version (QOL-FV) scale. Relationships between socio-demographic characteristics and QoL scores were analyzed using the Mann-Whitney U, Kruskal Wallis and Crosstabs tests. Results: The mean age of the female relatives was 37.6 years, and nearly 48% had a university education. It was found that first degree relatives had worse QoL in all domains except physical wellbeing than second degree relatives. Conclusion: This study showed that being female relatives of BC, especially first-degree, affect QoL negatively. Health care providers are of an important role in the stage of information related to genetic influence of BC.

The methanol extract of Diospyros peregrina bark was studied for its effect on the central nervous system (CNS) using the pentobarbitone induced sleeping time test, the open field test and the hole cross test in Swiss albino mice. The present investigation revealed that the extract, at the doses of 250 and 500 mg/kg, significantly prolonged the pentobarbitone induced sleeping time in mice though the onset of sleep was delayed as compared to the control. In open field test, the depressing effect was prominent from the second observation period (30 min) and persisted throughout the entire experimental period (240 min). In the hole cross test, the depressing effect was observed from the second observation period (30 min) and persisted up to fifth observation period (120 min) for 250 mg dose group and up to sixth observation period (180 min) for 500 mg dose group. These results support the finding that D. peregrina bark extract at the above doses has CNS depressing effects and indicate that D. peregrina bark may contain biologically active constituent(s) having CNS depressant activity.

This article extracted feasible elements for an environmental education program from the 'Intelligent Life', an integrated subject of the 7th elementary school curriculum, and designed a program for second graders in the elementary school and applied it to them in order to examine how the students' environmental altitudes changed. In the controlled class, the instruction followed the lessons specified in the 7th national curriculum faithfully while for the experimental class 1, only the inquiry activity-based environmental education program was applied. Moreover, in experimental class 2, the inquiry activity-based environmental education program was implemented and wrap-up activity was performed as well with the products. To verify the program, questionnaires on the change of environmental altitudes were distributed and analyzed total three times in the pretest, posttest 1(right after the program), and posttest 2(30 days after the program). T-test was carried out with the SPSS 12 program to verify the effect of the applied program. To make up for the quantitative analysis, qualitative analysis was also conducted. The followings show the results gained after the program was implemented. First, This program showed a significant difference(p<.05) in the students' formation of environmental altitudes. Second, it was verified that the inquiry activity-based environmental education class that reorganized the second grade elementary students' 'Intelligent Life' subject had a more positive effect in the cultivation of environmental altitude than the class that followed the present curriculum as it was. It will be necessary to perform follow-up researches on the relativity between curricula for kindergarteners and lower grade elementary school students.

The prediction for tool life is one of the most important factors for increasing reliability, stability, and productivity of manufacturing system. This paper deals with a tool life prediction method in view of reliability assessment for cutting tools. In this study, flank wear was focused among multi-factors deciding the tool wear state. First, tool life was predicted by correlation between flank wear and cutting time, based on the extended Taylor tool life equation of turning, including parameters of cutting speed, feed rate, and cutting depth. Second, each of cutting conditions of end-milling was equivalently converted to apply ball end-mill data to the extended Taylor equation. The web-based prediction program for tool life was developed as one of reliability assessment programs for machine tools.

Objective: This study aimed to analyze the changes and predictive factors of mothers' parenting competencies during their children's second to third grades in primary school. Methods: We used the data from the Panel study of Korean Parental Educational Involvement. We classified 373 mothers into three groups, 'reduced' parenting competency, 'maintained' parenting competency, and 'increased' parenting competency, and conducted one-way variance analysis and multinomial logistic regression analysis. Results: First, the mothers' parenting competency decreased between their children's 2nd year and 3rd year in primary school. Second, the 'reduced', 'maintained', and 'increased' groups differed from each other in the degree of change in self-system competency, level of understanding of school life, number of counseling sessions with homeroom teachers, and social networking. Third, the degree of change in self-system competency and social networking predicted the increase in mothers' parenting competency. The degree of change in self-system competency and the level of understanding of school life predicted the maintenance of mothers' parenting competency. Conclusion/Implications: This study, for the first time, has revealed the change in mothers' parenting competency and its predictive factors after the second year in primary school. How to support the growth of mothers' parenting competency was also discussed.

This study examined the influences of participation in the free semester on school life satisfaction and interest in classes and whether the effect persisted longitudinally. The participants were students from middle schools located in large cities: 451 students in the experimental group and 466 students in the control group. Only the students of the experimental group participated in the free semester. The data were collected at the end of the free semester for three years, and the results are as follows. First, the school life satisfaction of students in the experimental group was significantly higher than those in the control group until the second year but not in the third year. Second, there was no difference in interest in the main subject classes between the experimental and control groups until the third year. Third, students' interest in art and sports classes in the experimental group was significantly higher than those in the control group until the second year but not in the third year. These findings suggest that long-term planning and management of the institution rather than short-term introduction is required for the continuous effects of the free semester.

In contrast to apartments, detached houses offer the possibility of more than one entrance connecting interior and exterior spaces. This study examines the location, function, and use of second doors in detached houses in rural areas. The study employs survey and interviews conducted in 2015, focusing on 18 detached houses among 40 houses previously surveyed in 1995. In 1995, 21 second doors were found, while in 2015, 19 were found. The study led to the following conclusions. First, most houses did have second doors installed by 1995 or 2015. Second doors tended to be installed in kitchen and utility rooms. The function of second doors was most closely connected to the kitchen because utility rooms were placed adjacent to kitchens. Secondly, changes in the use and number of second doors were changes in family life cycle and composition, the need for new equipment facilities, the use of new architectural materials, and the installation of new second doors for extension of space. Finally, exterior spaces accessed by second doors tend to be a meeting of semi-interior or semi-exterior space and exterior space only. Those spaces tended to be designed for kitchen fixtures or to support kitchen activities.
