Purpose : This study aimed to identify intensive care units (ICU) nurses' experience of traumatic events, deliberate rumination, self-disclosure, social support, and post-traumatic growth (PTG), and to explore relationships among the variables. Methods : Participants were 157 nurses who have provided direct patient care for six months or more in ICUs at a university hospital. Collected data were analyzed using descriptive statistics, independent t-tests, one-way ANOVAs, Pearson correlations, and multiple linear regressions using the SPSS/WIN version 23.0. Results : The PTG was found to be significantly associated with deliberate rumination (r=0.36, p<.001), self-disclosure (r=0.39, p<.001), and social support (r=0.54, p<.001). Factors that affect PTG significantly were found in the order of social support (𝛽=0.40, p<.001), self-disclosure (𝛽=0.25, p<.001), and deliberate rumination (𝛽=0.24, p<.001). The final regression model explained 40.1% of the variance of PTG (F=26.33, p<.001). Conclusion : The influencing factors identified in this study on PTG, including social support, self-disclosure, and deliberate rumination should be included in programs to promote PTG for ICU nurses who may experience traumatic events repeatedly.

This study used the data of students from the 6th grade to the 3rd grade of middle schoolin the Korean Educational Longitudinal Study 2013 and classified them into subgroups with similar longitudinal changes in math academic achievement. In addition, the influence of longitudinal changes in the group's academic self-concept and teachers and parents academic support on the longitudinal changes in math academic achievement were analyzed, either directly or indirectly. As a result of the analysis, it was found that the academic self-concept of each group had a positive influence on the academic achievement in mathematics. In addition, the academic support of teachers and parents was found to have a positive influence on the academic achievement in mathematics through the mediating of the academic self-concept. In terms of direct and indirect influence on academic self-concept and math vertical scale scores, it was found that teachers' academic support had more influence than parents' academic support. The educational implications of these points were discussed.

Purpose : This study was to explore the long-term effects of breast cancer prevention volunteering on self-efficacy, depression, and posttraumatic growth among survivors with breast cancer. Methods: This pilot study utilized a longitudinal design. Participants were 14 women with breast cancer who participated in the breast cancer prevention educational program The data were collated between February and August in 2013. Self-report questionnaires were used to measure the self-efficacy for self-management of breast cancer, depression, and posttraumatic growth at pre-education(T0), 1 month(T1), 3 months(T2), and 6 months(T1) post-education. A generalized estimating equation regression model was used to identify the effects. Results: The scores of self-efficacy increased significantly at T1(${\chi}^2$=5.56, p=.0l8) and D(${\chi}^2$=4.56, p=.033) compared with T0. Depression and posttraumatic growth remained stable with fairly good levels throughout the 6-month period. Conclusion: The results of this study suggest that breast cancer prevention volunteering in survivors with breast cancer can be effective for enhancing their self-efficacy and maintaining psychological well-bang. Also the study showed that such volunteering activity could be a useful program not only for the general public but also for breast cancer survivors.

This study examined the effects of a 4 week, 8 session LCSI programs on the self-efficacy, adjustment to college of undergraduates. The number of participants was 39 students at one region. For statistical analysis, descriptive statistics, paired t-test, and Pearson correlation were used with SPSS WIN 18.0. The results are summarized as follows. The self-efficacy and underlying factors of self-efficacy in self-confidence, sense of self-regulated, task difficulty increased significantly, and the underlying factors of adjustment to college life academically, socially, emotionally, physically, love of the university, and adjustment to college increased significantly. Therefore, the self-growth program using LCSI, self-efficacy and adjustment to college life appears to have significant effects, and the LCSI program is more useful to consider the characteristics of each person by applying a range of situations to plan and deliver, such as communication or subjects, and conflict management in a variety of situations.

Purpose: This study aimed to develop and test a model for posttraumatic growth among cured patients with COVID-19. This model was based on Calhoun and Tedeschi's Posttraumatic Growth model and a literature review. Methods: The participants comprised 223 patients cured from COVID-19 who were ≥ 19 years of age. The data were collected through an online questionnaire from March 21 to 24, 2022. The assessment tools included the Impact of Event Scale: Revised Korean version, the Connor-Davidson Resilience Scale, the Distress Disclosure Index, the Multidimensional Scale of Perceived Social Support, the Korean version of the Event-related Rumination Inventory, and the Korean version of the Post-traumatic Growth Inventory. Data were analyzed using the IBM SPSS version 24.0 and IBM AMOS 26.0. Results: The modified model showed appropriate goodness of fit (χ² = 369.90, χ² /degree of freedom = 2.09, SRMR = .09, RMESA = .07, CFI = .94, TLI = .93). The post-traumatic growth of cured patients with COVID-19 was explained through distress perception, self-disclosure, and deliberate rumination, with the explanatory power being 70.0%. Conclusion: This study suggests preparing a disaster psychology program involving experts who can activate deliberate rumination is necessary. Further, this study may serve as basic data for developing a program to enhance the post-traumatic growth of patients cured from COVID-19.

KEPRI (Korea Electric Power Research Institute) has studied planar type solid oxide fuel cell (SOFC) stacks using anode-supported cells and kW class co-generation systems for residential power generation. In this work, a 1 kW SOFC system consisted of a hot box part, a cold BOP (balance of plant) part, and a hot water reservoir. The hot box part contained a SOFC stack made up of 48 cells, a fuel reformer, a catalytic combustor, and heat exchangers. Thermal management and insulation system were especially designed for self-sustainable operation in that system. A cold BOP part was composed of blowers, pumps, a water trap, and system control units. When the 1 kW SOFC stack was tested using hydrogen at $750^{\circ}C$, the stack power was about $1.2\;kW_e$ at 30 A and $1.6\;kW_e$ at 50 A. Turning off an electric furnace, the SOFC system was operated using hydrogen and city gas without any external heat source. Under self-sustainable operation conditions, the stack power was about $1.3\;kW_e$ with hydrogen and $1.2\;kW_e$ with city gas respectively. The system also recuperated heat of about $1.1\;kW_{th}$ by making hot water.

In this study, a synthesized poly(amino acid) self-assembly grafted with valine molecules was investigated on the skin activity of skin growth factors. The amphiphilic grafted poly(amino acid) derivatives were successfully synthesized by varying of degree of substitution(DS) and polymerization (DP) with valine molecules forming a β-sheet structure. Then, the pro-collagen biosynthesis of EGF(epidermal growth factor) was improved by 20%, and the inhibitory ability of tyrosinase activity was increased by 6.5 times by self-assembling of EGF with the poly(amino acid)s having β-sheet structures. This strategy of preparing protein self-assembly with poly(amino acid) derivatives will help improve the stability of protein growth factors and use it in medicals as well as cosmeceuticals through skin improvement.
