The purpose of this study was to develop the Children's Social Support Scale to assess three potential aspects of social support in elementary school age children ; the children's subjective apprasials of family, peer, and teacher support ; the frequency of supportive behaviors available from the child's support network; and the size of children's social support network. The subjects of this study were 380 children of forth and sixth graders in elementary schools located in Seoul. The 68 items(perceived support scale 30 items, enacted support scale 35 items, and support network 3 items) were analyzed by the statistical methods of item analysis, principal factor analysis, Factor analysis revealed that a three factor solution was the best for the Perceived Support scale ; family peer, teacher support. Enacted Support scale comprised of three factors; emotional, self-esteem, and informational support. Support Network scale was composed of emotional, self-esteem, and informational support network. Reliabilities for the domains ranged form .75-89. It was concluded that the children's Social Support scale in general is acceptable for use in Korea.

While numerous researchers have identified factors that explain social commerce-shopping behaviors, they have left one type rather understudied-trait-based antecedents. The ways consumer behavior is affected by their personal trait-this study therefore proposed and tested hedonic shopping tendencies. Findings indicate that hedonic shopping tendencies are a robust predictor of social support, consumer engagement, and impulse buying. Also, social support and consumer engagement affect social commerce intention and consequently social commerce frequency. Analysis of the results demonstrated a positive relationship between social support and consumer engagement, and the positive relationship between impulse buying and social commerce frequency.

The effect s of social support on post-stroke depression were investigated. Social support was classified into three categories : primary caregiver's, significant other's, and professional support. And primary caregiver's and significant other's support were divided into their relation, living state (which means they living together or not), frequency which they met at, and perceived satisfaction about the support, respectively. Professional support was divided into number of professionals who take care of, frequency they met at, and perceived satisfaction. The subjects were 254 stroke patients who had been discharged and were taken follow-up care at the out patient department. The depression was measured using CES-D. Out of the primary caregiver's support, only relation and perceived satisfaction were identified to affect the post-stroke depression. The patients who primarily their spouse takes care of were less depressed than those who their adult children take care of. None of the significant other's support affects the post-stroke depression. Only perceived satisfaction of the professional support was found to affect the post-stroke depression. So it was found that the quality, not the amount, of care was important to post-stroke depression. These results also support the claim that the facilities and teaching programs for primary caregivers are necessary.

In the design of transformer winding, natural vibration frequency is an important parameter. This paper presents a 2D model to calculate axial vibration natural frequency of power transformer winding based on the elastic dynamics theory, and according to the elastic support equivalent principle of radial pressboards. The 3D model to calculate natural vibration frequency can be simplified as a 2D one as the support of pressboards on the winding is same. It is verified that results of the 2D model are consistent with those of 3D one, but the former can achieve much higher calculation efficiency. It shows that increasing the width and number of pressboards can improve axial natural frequency through formula analysis and simulation, and also the relations between the changes of axial pre-compression and axial natural vibration frequency on the windings are investigated. Finally, the proposed 2D model's effectiveness is proved when compared with tested ones.

Formwork is a temporary structure that supports its weight and that of freshly placed concrete as well as construction live loads. In constructions site, pipe supports are usually used as shores which are consisted of the slab formwork. The strength of a pipe support is decreasing as it is frequently being used at the construction site. Among the accidents and failures that occur during concrete construction, there are many formwork failures which usually happen at the time concrete is being placed. The objective of this study is to find out the strength change of used pipe support and unused pipe supports according to aging. In this study, 2857 pipe supports were prepared. Among these pipe supports, 2337 pipe supports were lent to the construction companies free of charge. 520 pipe supports were kept on the outside. Compressive strength was measured by knife edge test and plate test at each 3 month. Test results show that the strength of unused pipe supports as well as used pipe supports was decreasing according to age, use frequency and load carrier, and the strength of used pipe supports was lower than the strength of unused pipe supports at the same age. So, the strength of used pipe supports from 191 days to present day was not satisfied the specification of KS F 8001. In this study, the strength of pipe support according to age, use frequency and load carrier was predicted using SPSS 12.0. It was known that the strength of pipe support using for 5 years was reduced to 42.8%. According to these results, it shows that attention has to be paid to formwork design using used pipe supports. Therefore, the present study results will be able to provide a finn base to prevent formwork collapses.

Mobile phones work by transmitting and receiving radio frequency microwave radiation. The radio frequency (RF) emitted by mobile phones is stronger than FM radio signal which are known to cause cancer. Though research and evidence available on the risk of cancer by mobile phones does not provide a clear and direct support that mobile phones cause cancers. Evidence does not also support an association between exposure to radio frequency and microwave radiation from mobile phones and direct effects on health. It is however clear that lack of available evidence of cancer as regards the use of mobile phone should not be interpreted as proof of absence of cancer risk, so that excessive use of mobile phones should be taken very seriously and with caution to prevent cancer.

This study examined the relationship between SNS use and individual psychological well-being on Instagram. In particular, this study sorted three types of perceived social support-informational, companionship, and self-esteem-to investigate how they influenced individual life satisfaction and loneliness. Results from a survey of 174 college students showed that: (1) frequency of Instagram use was a significant predictor of all three types of perceived social support; (2) status updates had positive effects on perceived self-esteem support, while posting photos was a significant predictor of perceived companionship support; (3) browsing others' profiles was a significant negative predictor of perceived self-esteem support and finally (4) perceived companionship social support had a positive effect on life satisfaction, whereas self-esteem social support had a negative effect on loneliness. These findings imply that Instagram users obtain specific types of social support depending on which activities they engage in and that different types of social support have different effects on well-being.

Purpose: The purpose of this study was to understand the effects of infection control fatigue and social support on burnout among nurses during the Coronavirus Disease 2019 (COVID-19) pandemic. Methods: This study is a descriptive survey study designed to confirm the effects of nurses' infection control fatigue and social support on burnout among nurses during the COVID-19 pandemic. The collected data were analyzed using frequency, percentage, mean, standard devia analyzed using frequency, percentage, mean, standard deviation, independent t-test, One-way ANOVA, Scheffe test, Pearson's correlation coefficient, and stepwise multiple regression analysis using SPSS Statistics 26.0. Results: An analysis of the correlations between fatigue from infection control, social support, and burnout showed a positive correlation between burnout and fatigue from infection control (r=.39, p<.001), and a negative correlation between burnout and social support (r=-.29, p<.001). Conflict and lack of support due to uncertain circumstances (β=.51, p<.001), support from supervisor's (β=-.22, p<.001), and experience of infection management education during the previous 1year (β=-.15, p=.007) were identified as the factors that influenced burnout among nurses, and explained 39.0% of the variance in burnout. Conclusion: The results of this study demonstrate that fatigue from infection control and social support influence burnout levels among nurses, which suggests the need to establish a new kind of work culture. Additionally, the findings call for the development and implementation of interventional programs that can reduce fatigue from infection control and increase social support for nurses.
