The purpose of this study was to examine the relation of stress and perceived social supports to problem behavior during childhood, with particular emphasis on the main and stress-buffering effects of perceived social supports. Such demographic data as parents' educational level, father's job, mother's employment, family income, and child's sex and age were also in chided in the study. Statistical techniques were ANOVA, t-test, and multiple regression. Major findings were that behavior problems of children increased with children's stress and decreased by perceived social supports. Perceived social supports moderated the relation between children's stress and problem behavior. Children's stress and perceived social supports differ by educational level of parents, father's job, and family income. Behavior problems of children were differed by family income, father's educational level and job. Children's stress and behavior problems differed by sex and age in some sub-domains, but perceived social supports did not differ by children's sex and age. Perceived social support from friends was the most influential factor affecting children's problem behavior. Therefore, friends may be considered the most important source of social support that is available for adjustment and for coping with stress during childhood.

This study examined the effects of the minimum horizontal load on the structural behaviors and safety of system supports. The minimum horizontal load was frequently ignored in the design of system supports even though the level of that load was specified in the code and guide in Korea such as 'Standard Specification in Temporary Construction' and 'Guide to Installation of Shores for a Concrete Bridge'. To examine the effects of considering the minimum horizontal load, the finite element analysis were performed for various system supports. By varying installing parameters of system supports such as the vertical member spacing, the installation height, and the thickness of slab, the maximum combined stress ratios were estimated to investigate the structural safety of system supports. The results showed similar axial stress in vertical members but an increase in bending stress with a consideration of the horizontal load. The combines stress ratios are remarkably increased due to the consideration of the horizontal load. Consequently, the system supports, which were initially estimated to be safe when only the vertical loads were considered, were changed to be unsafe in most cases by the effects of the both the vertical and horizontal stresses. Therefore, the minimum horizontal load following the code and the guide is an essential load that could control the structural safety of system supports.

Purpose: The aims of this study were to describe the levels of personal coping resources, perceived organizational supports, and job stress, and to examine factors that affect job stress in hospital-based home care nurse practitioners. Methods: A cross-sectional survey was conducted. Data were collected from 170 subjects with a structured questionnaire from April to July, 2016 and analyzed using descriptive statistics, t-tests, One-way ANOVA, Pearson's correlation, and multiple regressions. Results: The means for personal coping resources, perceived organizational supports, and job stress were $3.7{\pm}0.43$, $3.4{\pm}0.55$, and $3.4{\pm}0.55$ out of 5, respectively. Personal coping resources and perceived organizational supports were significantly correlated. However, both had no associations with job stress. In the multiple regression analysis, the experiences of home care nursing and hospital location were found to be predictors of job stress. Both personal coping resources and perceived organizational supports were not statistically significant predictors of job stress. Conclusions: It is necessary to carry out organization-based educational programs and support systems aimed at enhancing personal abilities to cope with stress at work. Additionally, further studies are needed to identify other hospital-related characteristics that can lead to job stress in home care nurse practitioners.

Purpose: The purpose of this study is to construct and verify a path model for the influencing factors on occupational stress of Vietnamese migrant workers in Korea. Methods: Participants were 193 Vietnamese migrant workers recruited from Foreign Workers Support Centers. Data were collected by a self-administered survey with copies of a Questionnaire written in Vietnamese. Data were analyzed with descriptive statistics, Pearson's correlation coefficients and path analysis using SPSS/WIN 23.0 and Amos 20.0 program. Results: Length of residence, homeland friends' and Korean colleagues'supports, and acculturation have been found to have significant direct effects on occupational stress of Vietnamese migrant workers. Meanwhile, Length of residence, homeland friends', Korean colleagues', and their families' supports showed indirect effects on their occupational stress. What had the greatest direct effect on occupational stress of Vietnamese migrant workers was Korean colleagues' support. Conclusion: For reducing occupational stress of Vietnamese migrant workers, it is necessary to strengthen their Korean colleagues' supports in work places. In addition, community organizations should take strategies to enhance homeland friends' supports and to improve acculturation of Vietnamese migrant workers.

Ceramic honeycomb structures have performed successfully as catalyst supports for meeting hydrocarbon, carbon monoxide and nitrous emissions standards for gasoline-powered vehicles. Three-way catalyst converter has to withstand high temperature and thermal stress due to pressure fluctuations and vibrations. Thermal stress constitutes a major portion of the total stress which the ceramic catalyst support experiences in service. In this study, temperature distribution was measured at ceramic catalyst supports. Thermal durability was evaluated by power series dynamic fatigue damage model. Radial temperature gradient was higher than axial temperature gradient. Thermal stresses depended on direction of elastic modulus. Axial stresses are higher than tangential stresses. Tangential and axial stresses remained below thermal fatigue threshold in all engine operation ranges.

A steel silo traditionally consists of a cylindrical and a conical shell. In order to facilitate emptying operations, the cylinder is placed on local supports. This may lead to dangerous stress concentrations and eventually to local instability of the cylindrical wall. In this contribution, the locally supported cylinder is strengthened by means of ring stiffeners and longitudinal stiffeners and the effect of their dimensions on the buckling stress is investigated. This study leads to a number of diagrams, each of them representing the effect of one of the dimensions on the buckling stress. In each diagram, the failure pattern corresponding to the buckling stress is indicated.

Vibration behavior of an initially stressed beam on discretely spaced multiple elastic supports has been studied and a theoretical formulation of the system is derived using the variational principle. Unlike beams on an elastic foundation, discretely spaced supports can distort the beam mode shapes when the supports have rather large stiffness, i.e. usually expected beam modes cannot be obtained, but rather irregular mode shapes are observed. Conversely, irregular modes can be recovered by changing initial stress. Since support location is closely associated with the dynamic characteristics, this work also discusses eigenvalue sensitivity with respect to the support position and some numerical examples are investigated to illustrate the above findings.
