The aim of this research is to verify the mediating role of optimism and self-efficacy on the association between social support and depressive symptoms on among college students. 329 college students answered the survey questionnaires which assessed their social support, depressive symptoms, optimism, and self-efficacy. The results revealed that the higher levels of social support predicted the lower levels of depressive symptoms, the higher levels of optimism, and self-efficacy. In addition, the higher levels of optimism and self-efficacy predicted the lower levels of depressive symptoms. Lastly, the mediation analysis indicated that optimism and self-efficacy mediated the negative relationship between social support and depressive symptoms. That is, college students who highly perceived social support reported higher levels of optimism and self-efficacy, which led to lower levels of depressive symptoms. Finally, the implication and limitations of the present research were discussed and the directions for developing research were suggested.

The purpose of this study is to analyze the general characteristics, effect size, and qualitative indicators of self-advocacy studies of people with developmental disabilities published in domestic academic journals and theses. For this purpose, among a total of 2153 papers related to self-advocacy published from 2000 to 2023, 41 studies with developmental disabilities as the keyword were selected, and the specific research results are as follows. Based on the results of this study, when developing a language intervention program related to self-advocacy for people with developmental disabilities, it is recommended to develop an intervention program based on the number of sessions of 10-19 in a learning situation with 20-30 people in adolescents and adults, or during the transition period. There are many studies limited to educational aspects such as special education and integrated education, and by applying this, it is hoped that a self-advocacy language intervention program will be developed at the level of language rehabilitation that can effectively and sophisticatedly assert self-assertion and self-rights after experiencing difficulties in communication.

Purpose : This descriptive research study aimed to investigate the relationship among academic self-efficacy, sleep quality, and quality of life(QoL) and to identify the factors that affect quality of life(QoL) in nursing students during the COVID-19 pandemic. Method : A total of 214 nursing students from three South Korean colleges were included in the study. Collected data were analyzed using the SPSS/WIN 21.0 program. Independent t-test and one-way analysis of variance were used to analyze the differences in academic self-efficacy, sleep quality, and quality of life(QoL) according to general characteristics. In addition, post-hoc Scheffè test and Pearson's correlation coefficient were used to examine the relationship among the three parameters. Stepwise multiple regression analysis was conducted to identify influential factors on the nursing students' quality of life(QoL). Results : The average academic self-efficacy, sleep quality, and quality of life(QoL) scores were 3.15±0.27, 32.28±7.54, and 81.12±13.11, respectively. Quality of life(QoL) positively correlated with academic self-efficacy but negatively correlated with sleep quality. Academic self-efficacy negatively correlated with sleep quality. Sleep quality, satisfaction with major, sex, average income, and academic self-efficacy influenced quality of life(QoL), whose explanatory power was 34.9 %. Conclusion : Sleep quality was the most influential factor of quality of life(QoL). However, further studies to validate our findings and studies focusing on developing intervention programs to improve nursing students' sleep quality and quality of life(QoL) are warranted.

It seemed. self-efficacy was determined by 'age' (F=2.74, p=.045), 'subjective academic level' (F=7.71, p=.001), and 'average smartphone usage time' (F=3.96, p=.009) showed a significant difference. Communication skills showed a significant difference in 'average smartphone usage time' (F=3.83, p=.011). The correlation between the variables of the study subjects showed that self-efficacy was negatively correlated with smartphone addiction (r=-.42, p<.001), and communication ability was positively correlated with self-efficacy. It was found that (r=.55, p<.001). 15) Conclusion : On the basis of the study results, the higher the nursing students' smartphone addiction, the lower their self-efficacy, and the higher their communication ability, the higher their self-efficacy. Therefore, intervention research is necessary to develop interventions for preventing smartphone addiction and increasing communication ability among nursing students.

Objectives: The objective of the study was to examine the clustering patterns and correlates of multiple health behaviors (MHBs) in middle-aged Koreans with metabolic syndrome (MetS). Methods: Data on sociodemographics, clinical characteristics, health behaviors (vegetable intake, physical activity, cigarette smoking, and alcohol consumption), and psychological characteristics were collected by a self-reported survey and medical examination from 331 individuals with MetS. Clustering of MHBs was examined by measuring 1) the ratios of observed and expected prevalence of MHBs, and 2) the prevalence odds ratios. A binomial logistic regression were conducted. Results: Men were more likely than women to engage in multiple unhealthy behaviors. Clustering of smoking and heavy drinking was exhibited in the participants. Women with high vegetable intake were more likely to be physically inactive, and those with inadequate vegetable intake were more likely to be physically active. Those with lower self-regulation were more likely to engage in unhealthy behaviors. Conclusions: The findings support the multiple health behavior approach as opposed to the individual health behavior approach. Emphasis of self-regulation is necessary in developing multiple behavior intervention for individuals with MetS.

This study examines the relationships between dietary self-efficacy, social support, depression, and weight-control behavior of children and adolescents. A total of 593 students (280 children and 313 adolescents) from schools in Seoul, Gyeonggi-do, Jeollabuk-do, and Daegu were surveyed using scales for dietary self-efficacy, social support, depression, and weight-control behavior. The data were analyzed through a frequency analysis, means and standard deviations, a t-test, a one-way ANOVA, the Tukey test, the Pearson's correlation, and a stepwise multiple regression analysis. According to the results, weight-control behavior was more likely in girls than boys, high-school students than elementary-school students, and obese/overweight students than normal/underweight students. The factors influencing children's weight-control behavior were general eating habits, the BMI, depression, food choice, and family support, in that order, and those influencing adolescents' weight-control behavior were general eating habits, gender, and the BMI, in that order. These results are expected to be useful as basic data for developing weight-control programs for children and adolescents.

This paper presents a novel concept of healing some of the damages in wind turbine blades (WTBs) such as cracks and delamination. This is achieved through an inherent functioning autonomous repairing system. Such wind turbine blades have the benefit of reduced maintenance cost and increased operational period. Previous techniques of developing autonomous healing systems uses hollow glass fibres (HGFs) to deliver repairing fluids to damaged sites. HGFs have been reported with some limitations like, failure to fracture, which undermines their further usage. The self-healing technique described in this paper represents an advancement in the engineering of the delivery mechanism of a self-healing system. It is analogous to the HGF system but without the HGFs, which are replaced by multiple hollow channels created within the composite, inherently in the FRP matrix at fabrication. An in-house fabricated NACA 4412 WTB incorporating this array of network hollow channels was damaged in flexure and then autonomously repaired using the vascular channels. The blade was re-tested under flexure to ascertain the efficiency of the recovered mechanical properties.
