The purpose of this article is to empirically suggest the necessity of reconsidering the new aptitude factors such as the ability to withstand work stress, to handle unusual events, and to work independently, in the respect that the environmental change in railway safety-critical worker's job should be flexibly reflected in the current aptitude management system. Besides, several ways of reducing the stress level for the railway safety-critical workers were suggested as well.

The purpose of this study was to survey the stressor, frequency of the stressor, level of the stress perceived by children in Korea. The subject were 417 children of 80 second graders, 117 third graders, 111 fourth graders and 109 fifth graders selected from three elementary schools in Pusan(214 male and 203 female). A questionnaire consisting of 70-item stress scale for children and demographic questions was used for mother. Statistics used for data analysis were frequency, ANOVA, and t-test. The major finding of this study were as follows: 1. Events receiving the highest ratings for magnitude of badness were mainly family related (parents separating; gradd parents getting sick/dying; parents getting sick). 2. Events receiving the highest ratings for frequency of occurrence were test, fighting with siblings, being picked on by other kids, staying home alone. 3. There appear signigcant differences for children's perception of stress due to the grade and the socioeconomic status.

Objectives : Alopecia areata has been known to be closely related to stress. The purpose of this study is to examine the relationship between stress and alopecia areata investigating how life events(which alopecia areata patients experience), amount of stress, coping strategy, and their personality type affect the oneset and aggravation of the disease. Methods : The subjects were 43 alopecia areata patients who visited the department of dermatology outpatients clinic, and 36 fungal infection diseases patients as the control group. They all completed Scale of Life Events, Coping Style Cheklist, Eysenck A-type Personality Inventory. The analysis of covariance with the age as covariate was carried out. Results : Compared to the control group, alopecia areata patients had significantly more stressful life events, and higher amount of stress, but there was no significant difference in coping strategy. Type A Personality is also resulted to have no significant relationship to alopecia areata. Conclusions : Alopecia areata patients had significantly higher amount of stress than the control group, and this result is consistent with the previous studies which suggest that stress contributes to the oneset of alopecia areata. The causual relationship between stress and alopecia areata should be further examined in order to be applied in clinical setting.

Objectives : To elucidate the transient effects on the risk of occupational injuries as acute events and establish so alternative proposal. Methods : The study population comprised a total of 302 workers randomly selected from applications for occupational injury compensation reported to the Inchon local labor office from January 1. 1999 to December 31. A case-crossover design, where each case serves its own control, was applied to this study. Through a telephone interview, workers provided useful data concerning five job related stressful events such as company transfer, work load change, overtime work, exchange duty, and work-part transfer. They were asked whether there were stressful events within a week of the occurrence of injury and the degree of stress. Exposure status from one year prior was used as control information. In the end, the data provided by 158 of selected persons was used for the analysis based on the quality of the data provided by the participants. A conditional logistic regression was used to discover the transient effects on the risk of occupational injuries as acute events. Results : The effects a company transfer and work load change on occupational injury was statistically significant on the risk of occupational Injuries as an acute event(RR=5.5, 95% CI=2.501-12.428; RR=3.1, 95% CI=1.963-5.017, respectively). Other stressful events were found to elevate the risk factor for the occurrence of occupational jujury, but were not significant. Conclusions : Our results suggested that transient stressful events elevated the risk factor for the occurrence of occupational injury.

We analyzed fault plane solutions of the recent twenty-two earthquakes which occurred from 2004 to 2006 in the central part of the Korean Peninsula by using P- and S-wave polarities along with SH/P amplitude ratios. The fault plane solution shows that strike-slip fault is dominant here, especially for the events with local magnitude equal to or greater than 3.0. However, some events with local magnitude less than 3.0 show normal fault or strike-slip fault with normal components. In the case of strike-slip fault, its orientation is almost in the direction of NNE-SSW to NE-SW almost parallel to the general trend of faults, while the compressional axis of the stress field trends ENE to E-W. The result is almost consistent with the stress field in and around the Korean peninsula, as reported previously. We cannot give any appropriate explanations to the normal faulting events along the western offshore and inland areas whether it is related to the local stress changes or tectonically unidentified extensional structures. Thus, an extension of investigations is desirable to clarify the cause of such phenomena.

Kinematic analyses of magmatic intrusions and faults can provide useful information on stress conditions and chronological relationships between dike emplacement and brittle deformation events. We studied structures in rocks exposed on a coastal platform in Geoje Island off the southern Korean Peninsula because of its well-developed dikes and faults. The geology of the study area includes the Cretaceous Seongpo-ri Formation, which is composed mostly of shale, sandstone, and hornfels intruded by magmatic dikes. Most of the dikes are developed along pre-existing structural features (faults and fractures), indicating that their emplacements were structurally controlled. Because dikes commonly open along the direction of the minimum principal stress, the direction of this stress can be obtained from dike geometry and orientation through the matching of piercing points on either side of a dike. In addition, the deformed dikes can give information regarding later deformation. On the basis of the kinematic analyses, we identified five deformation events in the study area, which are kinematically related to changes of the regional maximum principal stress. Results indicate that the structures in the study area have been controlled predominantly by episodes of reactivation of the NNE-trending Yangsan strike-slip fault, located to the northeast of the study area, under different stress regimes. In a wider tectonic context, the brittle deformation of the rocks of Geoje Island was probably induced by interactions among the Philippine Sea, Pacific, and Eurasian plates, including changes in subduction parameters with respect to the latter two plates over time.

Purpose: The purpose of this study was to investigate emergency nurses' reported traumatic events, professional quality of life and physical symptoms. Methods: The design of the study was descriptive. The respondents were 157 Emergency nurses with the majority were women (94.3% female and 5.7% were men). Data were collected from September 28 to December 1, 2011. The professional quality of life (ProQOL) instrument is conceptualized with three sub-dimensions (compassion satisfaction, burnout, and secondary traumatic stress), in addition information about traumatic events, physical symptoms and demographic variables were collected. Burnout and secondary traumatic stress (STS) are two parts of compassion fatigue. Data were analyzed using the SPSS/WIN 18.0 program and included descriptive statistics, t-test, ANOVA, Pearson's correlations. Results: Thirteen percent of the participants reported a high ProQOL. Compassion satisfaction was negatively correlated with burnout and physical symptoms, whereas, traumatic events had positive correlations with STS. Also, burnout and STS were positively correlated with physical symptoms respectively. Conclusion: Since the level of professional quality of life among emergency nurses was relatively low it is recommended that an intervention program for emergency nurses be instituted to improve compassion satisfaction and to decrease compassion fatigue and physical symptoms.

The development of operational performance indicators is of utmost importance for nuclear power plants, since they measure, track, and trend plant operation. Leading indicators are ideal for reducing the likelihood of consequential events. This paper describes the operational data analysis of the information contained in the Corrective Action Program. The methodology considers human error and organizational factors because of their large contribution to consequential events. The results include a tool developed from the data to be used for the identification, prediction, and reduction of the likelihood of significant consequential events. This tool is based on the resilience curve that was built from the plant's operational data. The stress is described by the number of unresolved condition reports. The strain is represented by the number of preventive maintenance tasks and other periodic work activities (i.e., baseline activities), as well as, closing open corrective actions assigned to different departments to resolve the condition reports (i.e., corrective action workload). Beyond the identified resilience threshold, the stress exceeds the station's ability to operate successfully and there is an increased likelihood that a consequential event will occur. A performance indicator is proposed to reduce the likelihood of consequential events at nuclear power plants.

The purpose of this study was to examine the stressors and coping strategies of school -age children and to explore the relationship between stressful life events and health symptoms and the effects of coping and trait anxiety which is theoretically considered to mediate the relationship between stress and health symptom. The study subjects consisted of 639 elementary school children in the fourth to sixth grade living in Seoul. Of the 639 subjects, 348 were boys and 291 were girls. The mean age was 11.35 (SD=.86). The Feel Bad Scale(FBS), Schoolager's Coping Strategy Inventory(SCSI), Spielberger's Trait Anxiety Scale for Children(STAIC), and Health Symptom Questionnaire (HSQ) were adapted for this study. A pilot study was undertaken to ascertain the reliability and validity of the instruments. The Cronbach alphas of FBS, SCSI, STAIC and HSQ were from .81 to .92. The Researcher and a research assistant visited the school and data were collected in the class using the questionnaire method after an explanation of the purpose and procedures was given to the children. Data collection was done during the period between Nov.25 to Dec.19, 1995. Using the SAS statistical program, percentages, t-test, ANOVA, correlation analysis, and multiple regression were used for data analysis. The result are as follows : 1. The mean score for the FBS was 204.79(range : 48-472) and there was a significant difference according to grade. The most severe stressors perceived by children were parental divorce and death or illness of family members. The most frequently experienced stressful life events were conflict with siblings and being home alone. 2. The mean score for the SCSI was 57.36(range : 9-118) and there was a significant difference according to grade. The most frequently used, and perceived as helpful, coping strategies were distraction and cognitive activities. 3. The mean score for the HSQ were 20.7(range : 0-81) and there were significant differences according to grade and sex. The percentage of the children answering that they perceived their health state as not good was 3.9%. 4. The mean score for the STAIC was 33.76 and there were significant differences according to grade and sex. 5. There was a significant relationship between stressful life events and health symptoms ( r=.53, p<.01). Also, Stressful life events were postively related with coping strategies(r=.39, p<.01). Trait anxiety was highly correlated with health symptoms(r=.72, p<.01). 6. To examine the multivariate effects of the variables to health symptoms, multiple regression was performed. Stressful life events, coping, trait anxiety, and health concerns were identified as significant variables. Explanation of the health symptoms by these variables was 56.78%. The study revealed that stressful life events correlated with health symptoms in school-age children and coping and trait anxiety had mediating effects on this relationship. The implication for nursing is that there is a need to develop supportive interventions for high risk population to decrease health problems due to stress. Also, it is recommended that a study be conducted to explore protective factors for the prevention of health problems in children.
