Despite the growing attention to the effective utilization of ICT system in workplace, there is an accumulation of evidence from the literature indicating that organizations do not utilize newly introduced ICT systems to their full functional potential and an amount of new implementations continue to fail. We explore the reasons for the underutilization of new ICT by focusing on the individuals' social networks. This paper investigates how the social networks influence individual adaptation to the new ICT and its related performance. Based on the coping theory, we establish a research model that explains the coping mechanism. Collected data are analyzed to test the proposed model and its hypotheses using PLS and UCINET. The results show that the coping effort mechanism of individuals can be explained in terms of their positions within social networks. We conclude the paper by discussing theoretical and practical implications for the research findings and by proposing future studies.

Mothers with cerebral palsy children have much stress that is related to the care of children with cerebral palsy and to other household duties, and this state of the mother has an effect on the cerebral palsy child and on other household member. Mothers in such stressful situations use various coping patterns. The purpose of this study was as follows : to develop instruments that can be used for measuring the stress and coping patterns of mothers with cerebral palsy children, and to test a hypothetical model on the relationship between the mother's stress, her coping patterns and the variable affecting the stress and coping patterns. The results of this study can be summarized as follows : 1. The stress scale was composed of 44 items and Cronbach's α was .94, and the coping pattern scale was composed of 19 items and Cronbach's α was. 80. The mean score of stress scale was 136.12 out of a total of 220, and the mean score of the coping scale was 72.87 in a total of 95. 2. In test of the hypothetical model, it was found that extra-care demand, the support of the husband, the degree of handicap, health status and self-esteem had statistically significant influence on the mother's stress(r=.285,-.262,-.133, -.126). And the support of the husband, formal support, informal support, and economic status were found to have statitically significant influence on the mother's coping patterns (r=.412, .178, 178, .138).

The purpose of this study is to examine the effects of foodservice employees' workplace harassment on their coping styles and intention to leave. Based on total 374 foodservice employees obtained from the empirical research, this study reviewed reliability and fitness of research model and verified total 3 hypotheses. SEM was conducted to test the validity of the proposed model and the hypotheses. The structural model provided an adequate fit to the data, $x^2=1,344.862$ (p<.001), df=420, GFI=.839, IFI=.900, CFI=.900, RMSEA=.076. To examine how employees' workplace harassment affects coping with harassment; workplace harassment had a significant effect on self-doubt (${\beta}=.401$, p<.001), ignored bully doubt (${\beta}=.621$, p<.001), and indirect or passive doubt (${\beta}=.527$, p<.001); whereas problem solving (${\beta}=-.094$, p>.05) did not. Furthermore, employees' workplace harassment (${\beta}=.126$, p<.05) had no significant effect on intention to leave. Employees' coping with harassment had a significant effect on intention to leave; especifically, among employees' coping with harassment elements, problem solving(${\beta}=-.572$; p<.001), self-doubt (${\beta}=.369$, p<.001), indirect or passive (${\beta}=.239$, p<.001), and ignored bully (${\beta}=-.161$, p<.01) had a significant effect on intention to leave. Limitations and future research directions are also discussed.

Objectives: This study was carried out in order to evaluate the overall process that the caregiving stress of parents of adult children with developmental disabilities affected their life satisfaction through the levels of family resilience, and coping styles on the basis of stress-coping-adaptation model of Lazarus and Folkman(1984). Method: For this purpose, the structured survey was conducted by 394 parents of adult children with developmental disabilities. The data was analysed by AMOS 20.0 version. Results: The findings can be summarized as follows: First, the structural equation model(SEM) analysis was conducted in order to examine the various paths that parents' caregiving stress affected their life satisfaction. The model's goodness-of-fit was fine($x^2=225.20$, df=95, p=000. RMSEA=.06, TLI=.95). There were significant relationships between caregiving stress and family resilience(${\beta}=-.36$, p<.001), emotion-focused coping style(${\beta}=.47$, p<.001), life satisfaction(${\beta}=-.53$, p<.001). Second, family resilience and emotion-focused coping showed mediating effects on the relationship between caregiving stress and life satisfaction. Conclusions: The strategies for enhancing family resilience and social services for applying effective coping methods should be expanded in order to diminish the caregiving stress of parents of adult children with developmental disabilities.

In this study, effective compressive strength and nodal zone of Strut-and-Tie Model are studied to propose a new design method for RC T-type pier coping for prevention of sudden brittle failure. The coping which transmits loads of bridge to pier should be properly designed to retain ductile behavior. In order to carry out this proper design using STM, tie must yield before concrete fails, and a stress at strut should not exceed a certain effective stress. Therefore, reasonable determination of the effective compressive strength of strut by considering stress states at the nodal zone exactly is very important. Since conventional STM is applied under assumption that all nodes are under hydrostatic stress state, actual non-hydrostatic stress state in nodal zone caused by geometrical characteristics, loading conditions, support conditions of structures can not be considered properly. In order to apply STM for design of RC T-type pier coping, the non-hydrostatic stress state of nodal zone is considered and effective compressive strength is proposed. Then, a new design method of RC T-type pier coping which applies the principle of superposition to obtain optimum ductile behavior is rationally designed.

The sample of this study consisted of 140 informal caregivers who provided care to the older adults(over 60 years of age) in Great Cleveland, USA. Self-rated questionnaires were utilized to collect information. The purpose of the study was to identify coping strategies most frequently utilized by informal caregivers of older adults and to examine predictors of the caregivers' health responses to the caregiving situation applying Lazarus and Folkman stress model(1984). Stepwise multiple regression was used to identify significant predictors among caregivers' demographic-socio-economic factors, older adult's dependency of activities of daily living(ADLs), caregiver's appraisal to the caregiving situation, and coping strategies. Informal caregivers (N=140) included in the study utilized help-seeking and problem-solving coping strategies more than self-blame and minimization of threat coping strategies. Caregivers' responses to the caregiving situation were observed by caregivers' perceived physical health, depression and life satisfaction. For perceived physical health, threat appraisal, older adult's dependency on ADLs, existential growth coping strategy, and monthly income accounted for 25% of the variance. Caregivers who appraised the caregiving situation as more threatening, reported higher dependency on ADLs, used more existential growth coping strategy, and had higher monthly income reported better physical health. For depression, threat appraisal, stress appraisal, existential growth coping strategy, self-blame coping strategy, and monthly income accounted for 48% of the variance. Caregivers who used more existential growth coping and less self-blame coping, appraised the situation as less threatening, less stressful, and had higher monthly income reported less depression. For life satisfaction, self-blame coping, existential growth coping, monthly income, stress appraisal accounted for 49% of the variance. Caregivers who used more existential growth coping, less self-blame coping, less stress appraisal, lower monthly income reported better life satisfaction. In conclusion, informal caregivers in this study utilized positive coping strategies such as problem-focused, existential growth, help-seeking, rather than negative coping strategies including self-blame. When they utilized positive coping strategies more often, caregivers experienced higher perceived physical health, higher life satisfaction and lower depression. Therefore, nursing intervention which utilized positive coping strategies is needed to enhance informal caregivers to have positive health responses to the caregiving demands.

Purpose: The focus of the study was on the selection-optimization-compensation (SOC) strategy to predict successful aging mediated by dyspnea symptoms in older adults with chronic obstructive pulmonary disease. The model was constructed based on the hypotheses that coping strategy and social support of the elders predict successful aging through the SOC strategies. Methods: Participants were 218 outpatients with chronic obstructive pulmonary disease recruited for the study. Data collection was done from March 25 to September 11, 2015, and analyzed using SPSSWIN 22.0 and AMOS 21.0. Results: The hypothetical model appeared to be fit to the data. Seven of eight hypotheses selected for hypothetical model were statistically significant. The SOC strategy has only significant indirect effects through dyspnea symptoms on successful aging. Coping strategy, social support, SOC strategies and dyspnea symptoms explained 62% of variance in successful aging. Conclusion: The SOC strategies with social support and dyspnea symptoms significantly explained successful aging among patients with chronic obstructive pulmonary disease. Nursing strategies should be focused on social support and coping strategies to optimize SOC strategies so that older adults with chronic obstructive pulmonary disease are able to manage dyspnea symptoms and eventually achieve successful aging.
