Purpose. To examine the effect of Taegyo-focused prenatal classes on maternal-fetal attachment and self-efficacy related to childbirth. Methods. Over 4 weeks, 49 women, 20 to 36 weeks of gestation participated in a prenatal program led by the nurse who developed it. In addition to Lamaze content it included; understanding ability of fetus to respond, sharing motivation, purpose of pregnancy, and preconceptions of experiencing childbirth, training in maternal-fetal interaction, writing letters and making a declaration of love to unborn baby. Using a pre-experimental design, data were collected by self-report, before and after program, using Cranley's Maternal-Fetal Attachment Scale (1981), and Shin's(1997) Labor Self-Efficacy Measurement. Results and Conclusion. Paired t-test showed significant changes in scores of maternal-fetal attachment (t=6.91. p<.001) and self-efficacy related to childbirth (t=10.19, p<.001). Taegyo opens the possibility of integrating Western ideas with Korean traditional health behavior. Incorporation of Taegyo into existing prenatal classes is recommended.

This study investigated cross-informant measures of peer group victimization. The subjects were 460 children in the fifth and sixth grades. Children completed questionnaires that assessed their own victimization feelings of loneliness, and self-perception. They also completed peer nominations concerning peer acceptance and rejection. The results suggest that self-reported victimization is more predictive of loneliness and self-perception, whereas victimization from peer nominations is more predictive of peer rejection and acceptance.

Two hundred and three students, second graders of a high school participated. Experimental group performed writing a weekly report, while the comparative group performed regular science lessons. The results of this study are as follows: First, MSLQ test showed that there was statistically significant difference in the self-directed learning skills(p<.05). For sub-factors of motivation region, such as internal goals, extrinsic goals, learning beliefs, task value, and self-efficacy and for sub-factors of learning strategy region, such as meta-cognition, peer learning, time management, critical thinking, and demonstrations showed statistically significant results. Second, TOSRA test showed that there was no statistically significant difference in the attitudes toward science (p>.05). However, for sub-factors, such as scientific inquiry and joy to science class showed statistically significant results. Third, there was no statistically significant difference in the academic achievement in Chemistry I class (p>.05). However, top and low achievement level showed statistically significant results.

This talk will begin with the demonstration of facile synthesis of silicon nanostructures using the magnesiothermic reduction on silica nanostructures prepared via self-assembly, which will be followed by the characterization results of their performance for energy storage. This talk will also report the fabrication and characterization of highly porous, stretchable, and conductive polymer nanocomposites embedded with carbon nanotubes (CNTs) for application in flexible lithium-ion batteries. It will be presented that the porous CNT-embedded PDMS nanocomposites are capable of good electrochemical performance with mechanical flexibility, suggesting these nanocomposites could be outstanding anode candidates for use in flexible lithium-ion batteries. Directed self-assembly (DSA) of block copolymers (BCPs) can generate uniform and periodic patterns within guiding templates, and has been one of the promising nanofabrication methodologies for resolving the resolution limit of optical lithography. BCP self-assembly processing is scalable and of low cost, and is well-suited for integration with existing semiconductor manufacturing techniques. This talk will introduce recent research results (of my research group) on the self-assembly of Si-containing block copolymers for the achievement of sub-10 nm resolution, fast pattern generation, transfer-printing capability onto nonplanar substrates, and device applications for nonvolatile memories. An extraordinarily facile nanofabrication approach that enables sub-10 nm resolutions through the synergic combination of nanotransfer printing (nTP) and DSA of block copolymers is also introduced. This simple printing method can be applied on oxides, metals, polymers, and non-planar substrates without pretreatments. This talk will also report the direct formation of ordered memristor nanostructures on metal and graphene electrodes by the self-assembly of Si-containing BCPs. This approach offers a practical pathway to fabricate high-density resistive memory devices without using high-cost lithography and pattern-transfer processes. Finally, this talk will present a novel approach that can relieve the power consumption issue of phase-change memories by incorporating a thin $SiO_x$ layer formed by BCP self-assembly, which locally blocks the contact between a heater electrode and a phase-change material and reduces the phase-change volume. The writing current decreases by 5 times (corresponding to a power reduction of 1/20) as the occupying area fraction of $SiO_x$ nanostructures varies.

Purpose: The purpose of this research was to evaluate the application of the Problem-Based Learning(PBL) in nursing with regard to the learning process and learning outcomes. Method: PBL modules were provided to the students so that they could identify the nursing problems related to nutrition, regulation, and elimination, and implement appropriate nursing interventions according to the problems. PBL was also used to develop ability to use self-evaluation for nursing intervention outcomes. The modules were developed by the authors for the course, Nursing 1(3 credits) at Y university, and used during one semester, March to June 2003. Evaluation of the learning process and learning outcomes was done by self-report questionnaires and a semi-structured self -report developed by the authors. Result: The PBL evaluation included role of the facilitators, group work process, and self-directed learning attitude. The students evaluated the facilitator's role positively in fostering positive interactions and cooperative study among students and stimulating students to apply various problem-solving strategies. Students evaluated their own group work performances as a good opportunity to improve their group work participation, contribution, cooperation, and leadership through the PBL session. Their responsibility for their own learning and develop self-directed learning attitudes to connect present learning to long-term goals. Conclusion: Critical thinking, problem solving skills, self-directed learning and group work accomplishments in undergraduate student nurses were fostered and improved through the PBL program.

Purpose: To determine the mediating as well as moderating effect on both the emotional labor and burnout of professional self-concept perspective organ transplantation coordinators (OTC)'. Method: A self-report questionnaire was collected from 86 OTCs nationwide. The data were analyzed using t-test, ANOVA, Scheffe' test, Pearson' Correlation Coefficients, AMOS 20.0, and multiple regression. Results: For effects of professional self-concept on emotional labor and burnout, higher emotional labor was related to higher burnout. When professional self-concept was mediated, emotional labor had a greater effect on burnout however, a partial mediating effect was detected. From the regression analysis with the independent variables of emotional labor (A) and professional self-concept (B), adding relation of both variables ($A{\times}B$) increased the explained variance to 56.3% ($p$<.05). It was confirmed that professional self-concept had a moderating effect on emotional labor and burnout. Conclusion: The results of this study indicate that, when professional self-concept was mediated emotional labor of an OTC decreased, and burnout decreased when professional self-concept was high. Also, by controlling professional self-concept, emotional labor and burnout decreased. Therefore, it's necessary to map out the environment and develop strategies to reduce emotional labor and burnout in organ transplantation coordinators.

Purpose: Non-Suicidal Self-Injury (NSSI), a highly prevalent behavior in adolescents, refers to the direct destruction of one's body tissue without suicidal intent. To date, the prevalence of adolescent self-injury in South Korea and its associated factors remain unknown. This study aims to determine the prevalence of self-injury in Korean adolescents as well as its associated factors. Methods: We assessed 717 middle school students by means of an anonymous self-report survey. Information about demographic characteristics, lifestyle, anxiety and depression, self-esteem, and parenting behavior was obtained. Data were analyzed using $x^2$ test, t-test and multiple logistic regression. Results: NSSI was reported by 8.8% of respondents. Univariate analyses showed associations of exposure to alcohol use, anxiety, depression, self-esteem, and parenting methods with self-injury. In multiple analyses, alcohol use, anxiety, and parental abuse were associated with lifetime self-injury. Conclusion: The rate of NSSI in the South Korea was found to be lower than those of other countries. As our study suggests that alcohol use, anxiety, and parental abuse are associated with lifetime self-injury, health care providers at school should take these factors into account when developing prevention and intervention programs for adolescents.
