Purpose: This study was done to identify the relationship of family function, self-efficacy and self-leadership, and to identify factors affecting self-leadership in adolescents. Method: Sampling was done using a convenience sampling method and 779 adolescents were recruited between June 4 and 15, 2012. Data were collected using self-report questionnaires which included general characteristics, family function, self-efficacy and self-leadership. Data were analyzed using descriptive, t-test, one way ANOVA, Scheffe test, Pearson correlation coefficient, and stepwise regression analysis with SPSS/WIN 19.0. Results: The major findings of this study were as follow; 1) There were significant relationships between self-leadership and family function (r=.36, p<.001), and self-efficacy (r=.51, p<.001). 2) Self-leadership was significantly associated with self-efficacy (${\beta}$=.42, p<.001), family function (${\beta}$=.20, p<.001), satisfactory relationships with teachers (${\beta}$=.12, p<.001), experience as a leader (${\beta}$=.10, p=.001), higher school records (${\beta}$=.17, p<.001), and medium school records (${\beta}$=.11, p=.001). These variables explained 40.4% of variance in adolescents' self-leadership. Conclusion: The results of this study indicate that there is a relationship between family function, self-efficacy and self-leadership in adolescents and that in developing intervention programs to promote self-leadership, in adolescents, these variables should be considered.

Objectives : The current study was conducted in order to investigate teachers' recognition of school bullying using a nationwide database of adolescents in middle and high school in Korea. Methods : Students in the 7th to 12th grades at 23 secondary schools participated in the current study during the fall of 2009. Subjects completed the self-report form of the Adolescent Mental Health and Problem Behavior Screening Questionnaire-II (AMPQ-II) and Symptom Checklist-90 Revised (SCL-90-R). In addition, relevant teachers used the teachers' rating scale of the AMPQ-II to report their students' status. Differences in the number of bullied students between teachers' recognition and students' report were explored. Results : A total of 2270 subjects provided relevant responses to the questionnaire. While the one-month prevalence of victimization according to students' self-reports was 28.9%, the recognized prevalence by teachers was only 10.6%. For prediction of the presence of school bullying according to students' self reports on the AMPQ-II, item 7 of the teachers' report on the AMPQ-II showed a sensitivity of 16%, a specificity of 92%, a positive predictability of 44%, a negative predictability of 72%, a false positive rate of 8%, a false negative rate of 84%, and an accuracy of 69%, respectively. No significant differences in subscores of students' self reports of the AMPQ-II and SCL-90-R were observed between bullied students who were recognized by teachers and those who were not recognized. In stepwise discriminant analysis, classification of teachers' item 2 and item 7 on the AMPQ-II with respect to school bullying according to students' reports showed an accuracy of 63.4%. Using this model, 75.2% of non-victimized subjects were classified correctly, while only 35.2% of victimized subjects were classified correctly. Conclusion : Despite the high prevalence in Korea, teachers' recognition of school violence among their students remains low. Pre-professional and continuing education to improve teachers' understanding of school bullying and knowledge of effective classroom-based prevention activities should be encouraged.

We report on a simple method of fabricating multimode transflective liquid crystal displays (LCDs) using the photoalignment technique. Using a self-masking process of ultraviolet light by the reflector as a photomask as well as a reflective mirror, the periodic multimode is obtained with no additional fabrication processes. Moreover, variations of the cell gap are not required for such trasflective LCDs

We report on low-voltage pentacene TFTs with a Al2O3/OTS as a gate dielectric. Improving device characteristics, we performed chemical modification of self-grown Al2O3 surface with an octadecyltrichlorosilane(OTS) self-assembled monolayer(SAM). As the result of this combination, the mobility was improved from 0.3 to $0.45\;cm^2/Vs$. In addition, we examined that the SAM dipole electric field have an influence on gate leakage current, transfer and output characteristics.

In this paper, we report our quantum mechanical approach for the analysis of FinFET in a self-consistent manner. The simulation results are carefully investigated for FinFET with an electrical channel length(Leff) of 30nm and with a fin thickness(Tsi) of 10～35nm. We also demonstrated the differences in the simulations for the classical and quantum-mechanical simulation approaches, respectively. These simulation results also imply that it is necessary to solve the coupled Poisson and Schrodinger equations in a self-consistent manner for analyzing the sub-30nm MOSFETS including FinFET.

Purpose: This study was conducted to examine the effects of a self-control promotion program on self-efficacy, self-care and physiological indicators of patients with diabetes who live in local communities. Method: This research was designed using a nonequivalent control group pre, posttest study. Data were collected from December, 2008 through March, 2009. The participants of the study consisted of 93 patients with diabetes who live in a local community. A self-control promotion program was provided for the experimental group for 12 weeks. Data were collected through self-report questionnaires and direct measurements, and analyzed using descriptive statistics, $X^2$-test, and repeated measures ANOVA. Results: There were significant differences in self-efficacy and self-care between the experimental and control groups. However, there were no significant differences in physiological indicators such as fasting blood sugar, HbA1C, BMI, and BP between the two groups. Conclusion: The results indicate that the self-control promotion program was effective in promoting self-efficacy and self-care, which are crucial factors in controlling diabetes mellitus. However, a longitudinal study needs to be done to confirm the effects of self-control promotion programs on long-term glucose control.
