Recently, as stress has become a major threat to people's health, there is a growing interest in wearable stress management services for stress relief. In this paper, we developed a wearable device(Care-on) capable of extracting changeable human voice information at each site and a Healthcare App(S-Manager) that enables stress management in real time using the wearable device. It collects and analyzes variable real-time voice information for each part of the person's body. And It also provides the ability to monitor stress conditions in a mobile environment and provide feedback on the analysis results in step by step in the mobile environment. We tested the developed wearable devices and app in a mobile environment and analyzed the results to confirm their usefulness.

Purpose: The purpose of the study was to identify the effect of stress on the relations between emotional intelligence and burnout among nursing college students. Methods: The study is a cross-sectional survey and the participants were 363 students attending a nursing college located in Seoul. Data were collected by convenience sampling using self-reported questionnaires that consisted of general characteristics, emotional intelligence, perceived stress and burnout. Data were analyzed by descriptive statistics, t-test, ANOVA, correlation, and multiple regression. Results: Findings of the multiple regression were as follows. First, emotional intelligence had a significant negative-effect on stress. Second, emotional intelligence had a significant negative-effect on burnout. Third, stress had a significant positive-effect on burnout and had a mediating effect on the relationship between emotional intelligence and burnout. Conclusion: Results of the study suggest that as a way to reduce nursing college students' stress and burnout, programs which help improve nursing college students' emotional intelligence should be developed and implemented.

This research investigated the moderating effects of children's negative emotionality, activity and sociability on the relation between maternal parenting stress and children's behavior problems. Participants consisted of 1,667 preschool children from the fifth wave of the Panel Study on Korean Children. EAS was used to measure the children's temperament. Mothers reported parenting stress and children's behavior problems. The results revealed that the magnitude of association between relation between maternal parenting stress and children's behavior problems was greater for high levels of negative emotionality and activity as well as low levels of sociability. The results support a diathesis-stress model in which high negative emotionality, activity and low sociability confer vulnerability for preschool children in a high stress family.

To measure the effect of the stress-strain dispersion across the installed waterproofing layer on the concrete surface, a strain gauge was attached to the gap between the waterproofing layer and the concrete structure at specified points of upper, center and bottom of the load-displacement simulation specimen, and the peak stress-strain at the displacement interface were measured and compared with stress-strain at other areas to analyze each material types' stress-strain dispersion ratio properties. Based on the results of the testing, it was shown that materials with high load-displacement resistance performance accordingly had high stress-strain dispersion ratio results, and the materials from highest performance to lowest performance were; CAS, SAS, PUC and CSC.

Objectives : The study is performed to investigate the influence of psychological stress on neck muscles tone and heart rate variability(HRV). Methods : This study was carried out with the data from stress response index score(SRI), surface electromyography(sEMG) and HRV. First subjects were divided into two group according to the SRI points. Subjects in group A had points of SRI in which lower than 30 points. Subjects in group B had points of SRI in which higher than 30 points. Then we investigated how to difference of the index of sEMG and HRV according to each groups. Results : In this study, the muscle contraction of both upper trapezius muscle in stress group were higher than non-stress group significantly. Complexity, root mean square of successive differences of R-R intervals(RMSSD), standard deviation difference between adjacent normal to normal intervals(SDSD), high frequency oscillation power(Ln(HF)), normalized HF(Norm HF) in stress group were lower than non-stress group significantly and normalized LF(Norm LF) was higher. Conclusions : This results show that the stress was associated with neck muscle condition and autonomic nervous system.

Purpose: The purpose of this study was to compare self-care behavior, diabetes-related stress and stress coping style among 3 blood glucose control groups (good, inadequate, and poor blood glucose control groups). Methods: Participants were 102 type 2 diabetic patients (good group: 41, inadequate group: 31, poor group: 30). Data were collected from Feb 19 to Mar 24, 2010 and were analyzed using Chi-square, Fisher's exact test and ANCOVA with SPSS/WIN 12.0. Results: Using ANCOVA with frequency of admission, and illness duration as covariates, significant differences were found among the 3 groups in self-care behavior (total score) and the exercise subscale. Using ANCOVA significant differences were found among 3 groups in diabetes-related stress (total score), emotional burden subscale and regimen distress subscale. Using ANCOVA no difference in stress coping was found among the 3 groups, but there was a significant difference in the problem-oriented coping subscale. Conclusions: Self-care behavior, diabetes-related stress, and stress coping style are factors influencing blood glucose control. The results of this study suggest that for improving blood glucose control, self care education program focused on diet and exercise in addition to stress management program for promoting problem oriented coping capability are recommended.

Specimens of 304 stainless steel were tested to failure at elevated temperatures under multiaxial stress states, uniaxial tension using smooth bar specimens, biaxial shearing using double shear bar specimens, and triaxial tension using notched bar specimens. Rupture times are compared for uniaxial, biaxial, and triaxial stress states with respect to the maximum principal stress, the von Mises effective stress, and the principal facet stress. The results indicate that the principal facet stress gives the best correlation for the material investigated, and this parameter can predict creep life data under multiaxial stress states with rupture data obtained with specimens under uniaxial stresses. The results also suggest that grain boundary cavitation, coupled with localized deformation processes such as grain boudary sliding, controls the lifetimes of the specimens.

This study examined the effect of parenting knowledge and mother-caregiver relationship on maternal parenting stress. The participants in this study consisted of 297 mothers of 1~3 years old children at daycare centers in Daegu, Korea. The participants completed questionnaires on their parenting knowledge, mother-caregiver relationship, and parenting stress. The results indicated that mothers' parenting knowledge and parenting stress were not-significantly related, but mother-caregiver relationship and mothers'parenting stress were significantly related. A close look at the effect of parenting knowledge and mother-caregiver relationship on maternal parenting stress, while maternal parenting knowledge did not influenced directly parenting stress, mother-caregiver relationship was a significant variable predicting mother's parenting stress. In particular, when a mother and caregiver develop a positive relationship, maternal parenting stress was lower. These results seem to indicate that the positive relationship between mother and caregiver is very important.

Purpose: The aim of this study was to analyze the effects of incivility experienced by clinical nurses on their job stress, and to identify the moderating effects of self-efficacy on the relationship between job stress and incivility. Methods: A structured self-report questionnaire was used to measure job stress, incivility and self-efficacy. Data were collected from 140 nurses currently working in three general hospitals of more than 300 beds. Data were analyzed using descriptive statistics, ANOVA, Scheffétest, Pearson correlation coefficient, hierarchical multiple linear regression with the SPSS Version 19.0 program. Results: Incivility from supervisors, patients and patients' families showed a significant effect on job stress and self-efficacy had an effect on incivility from patients and patients' families and also incivility from doctors and job stress. These variables have total explanatory power of 46.6% on job stress. Conclusion: The results indicate a need to recognize the seriousness and damage of incivility in order to reduce hospital nurses' job stress and to awaken nurses to the relationship of stress and incivility and establish institutional programs to combat incivility. Moreover, there is also a need to improve self-efficacy on the ward through hospital education and coaching.
