During past decades, several types of peptide-based scaffolds, ranging from simple aromatic dipeptide to small protein fragments, have been studied to understand the underlying mechanism and mimic to create artificial nano/microstructures. However, a limited number of design principles have still been reported in peptidic scaffolds allowing well-defined self-assembled structure formation, presumably due to the intrinsic large conformational flexibility of natural peptides. In this presentation, we report the first example of highly homogeneous, well-defined and finite architectures by the ${\beta}$-peptide self-assembly.

Purpose: This study was done to examine factors influencing cell phone addiction for middle school students by gender. Methods: The participants were 228 male students and 228 female students in two middle schools. Data were collected through self-report questionnaires, and analyzed using the SPSS/WIN 19.0 program. Results: Cell phone addictions of female students are higher than those of male students. Factors influencing cell phone addiction for male students were mimicry, sending text message on weekdays, immediate self-control, grade, syntony, and monthly call charge, explaining 42.2% of variance in cell phone addiction. Factors influencing cell phone addiction for female students were internet addiction, sending and receiving text message on weekends, immediate self-control, long-term self-control, use time, main use, syntony, and monthly call charge, explaining 46.8% of variance in cell phone addiction. Conclusion: The results indicated that cell phone addiction and its influencing factors differed by gender. Therefore the approach to effective cell phone addiction management program for middle school students should consider gender differences.

Purpose: To examine the effects of appearance satisfaction on school adjustment among adolescents and, further, the mediating effects of self-efficacy between appearance satisfaction and school adjustment. Methods: Conducted a self-report survey of 640 students consisting of sixth, eighth, and tenth graders in the Jeju Special Self-Governing Province. The collected data were analyzed through the independent-sample t-test, the One-way ANOVA, the Pearson's correlation analysis, and the hierarchical multiple regression analysis using the SPSS WIN 18.0 statistical program. Results: First, boys and girls showed statistically significant differences. Boys reported higher levels of appearance satisfaction, school adjustment, and self-efficacy than girls. Second, there were no significant differences in appearance satisfaction and self-efficacy according to the school level. However, statistically significant differences were observed in school adjustment between sixth and eighth graders. Third, students who thought they belonged to the upper class in terms of academic performance and family economy showed the highest level of appearance satisfaction, school adjustment, and self-efficacy. Fourth, there were positive correlations between appearance satisfaction, self-efficacy, and school adjustment. Fifth, self-efficacy proved to have mediating effects between appearance satisfaction and school adjustment among adolescents. In particular, it had a full mediating effect on the relation between appearance satisfaction and adjustment to school life, one of the subfactors of school adjustment. Conclusion: The results suggest that appearance satisfaction is a factor which influences adolescents' school adjustment and that self-efficacy is an important means of mediating between appearance satisfaction and school adjustment. The study is significant in that it highlighted the importance of self-efficacy as one of the important variables to consider when planning various educational programs to help adolescents adjust to their school. In the light of the findings, in an effort to enhance adolescents' self-efficacy and help them lead a harmonious school life in Korea's so-called 'lookism' society, it is necessary to develop and implement counseling programs and character education materials that help adolescents develop a positive perception of their appearance and build self-esteem and self-confidence.

The purpose of this study was to identify the relationship between emotional intelligence, academic self-efficacy, and self-leadership among nursing students. Subjects were 230 nursing students in South Korea. Data were collected using self-report questionnaires from September 1 to 30, 2015, and analyzed using frequencies, t-tests, ANOVA, Pearson's correlation, and multiple regression using SPSS Win 18.0. Self-leadership was significantly positively correlated with emotional intelligence and academic self-efficacy in nursing students. Students with higher emotional intelligence and academic self-efficacy showed higher self-leadership. Emotional intelligence and academic self-efficacy explained 40.2% of the total variance in self-leadership among nursing students. Therefore, to increase nursing students' self-leadership, it is necessary to develop and test programs to ensure an improvement in emotional intelligence and academic self-efficacy among nursing students.

Purpose : The purpose of this study was to investigate the effect of case-based learning application in human growth development classes on nursing students' problem-solving ability, self-directed learning ability, and academic self-efficacy. Methods : The research method was a self-report questionnaire before and after case-based learning for second-year nursing students who took the human growth development course at U University in K city. The collected data were statistically processed using SPSS WIN 21.0. Results : The results of the study showed that after case-based learning, problem-solving ability, self-directed learning ability, and academic self-efficacy were all significantly improved. In addition, as a result of examining the correlation between each variable after case-based learning, problem solving ability score and self-directed learning ability score (r=.54, ｐ<.01), and problem solving ability scores and academic self-efficacy scores (r=.44, ｐ<.01), were significantly correlated with self-directed learning ability scores and the academic self-efficacy reduction scores (r=.76, ｐ<.01). Conclusion : The results of this study suggested the need for various learning programs such as case-based learning to improve nursing students' problem-solving abilities and self-directed learning abilities and their application. In addition, to improve the learning self-efficacy of nursing students, a continuous and systematic study is suggested to develop and apply customized educational programs according to the learners' preferences. Since the sample group in this study was limited to one university, there were few cases and no control group, so there are limitations in generalizing the test effect, However, significant differences a were verified in the case-based learning pre-tests and post-tests.

Cerebral palsy, a range of non-progressive syndromes of posture and motor impairment, is a common cause of disability in childhood. Self-injurious behavior(SIB) is deliberate harm to the body without suicidal intend, often involving repetitive actions that cause tissue damage. One of the most common orofacial self-injurious behavior is chewing tongue, lip or oral mucosa. This kind of SIB in children is not common in normal children. High occurrence rates are observered in cases of syndromatic, mentally retarded children, and children with congenital disease. Various methods such as behavior modification, behavior control by drugs, body restraints, application of dental appliance, surgery and extraction of teeth have been suggested to control those self-injurious behavior. Using mouthguard as one of dental applainaces is the most conservative and appropriate method in terms of reducing oral self-injurious habits and protection of tissue. This case report describes a child with cerebral palsy who presented with self-injurious ulceration of lip and buccal mucosa. A modified mouthguard was effective in preventing self-injurious oral trauma in a child with cerebral palsy.

The purpose of this study was to investigate the mediating pathways of emotional regulators in relation to self-conscious negative emotions, including non-suicidal self-harm, guilt, shame, shyness, and internal hostility, further examining the gender difference in the mechanisms. The study subjects of were 652 college students from three universities in J district. Self-report questionnaires on self-harm, self-conscious negative emotions, and emotional control were administered to them. An analysis performed using model 4 of the process macro indicated that self-conscious negative emotions had a significant correlation with self-harming behavior and that this correlation was mediated by the emotional regulation of brooding. These results suggest that negative self-conscious emotions have a significant influence on self-harming behaviors, and brooding reinforces negative emotions then the risk of self-harming behaviors is amplified.

The purpose of this study was to report the effects of self-directed and self-regulated learning programs on elementary, middle, and high school students through meta-analysis of previous studies. For this research, 22 of previous studies were selected which were all conducted in the country, and calculated the effect size of 'standardized change of the mean difference' for many factors included in each research. The findings were as follows: first, the overall effect sizes of self-directed and self-regulated learning programs on elementary, middle, and high school students were .665 and .702 in the affective and cognitive domain, respectively, meaning that the self-directed and self-regulated learning programs had average or greater effects on elementary, middle, and high school students and exerted somewhat greater effects in the cognitive domain. Second, when the areas of moderating effects were divided into self-directed and self-regulated learning, the former and latter had more influences on the cognitive and affective domains, respectively. Third, the elementary school level recorded a larger effect size both in the affective and cognitive domains than the secondary school level. Fourth, the findings show that the characteristics of affective domain, "reflective thinking" and "self-confidence," recorded a very large effect size both at the elementary and secondary school levels. Finally, the programs were more effective when the application period was one to four weeks in the affective domain and more than four weeks in the cognitive domain. And, Significance and implications of this research were discussed.

Purpose: The aim of this study was to examine the relationship between handwashing knowledge and handwashing compliance in nursing students and to identify the moderation and mediation effects of self-efficacy and perceived behavioral control on the relationship. Methods: The participants were 172 nursing college students who completed the self-report measures. Data were analyzed using t-test, ANOVA, and Pearson correlation coefficient, Multiple regression analysis was used to test moderation and mediation effects. Results: The score for knowledge of handwashing was higher in participants who had completed fundamentals of nursing practicum (t=-6.54, p<.001) and the score for compliance with handwashing was higher in participants who had completed clinical practicum (t=-3.81, p<.001) or fundamentals of nursing practicum (t=-5.97, p<.001). Self-efficacy showed a significant moderation effect (z=2.21, p=.027) but not a mediation effect while perceived behavioral control had a significant mediation effect but not a moderation effect on the relationship between knowledge of handwashing and compliance. Conclusion: Findings indicate that clinical practicum and fundamentals of nursing practicum were helpful to nursing students in acquiring knowledge and in practicing proper handwashing technique. These findings suggest that continuing and repetitive education programs on handwashing need to be enhanced and strategies to strengthen self-efficacy and perceived behavioral control need to be included in education programs.
