This study investigated the stress of community residents in Kwang-Ju and Chonnam areas by using the General Health questionnaire(GHQ-60) as a instrument of stress measurement. The number of subjects were 445 residents who lived in three areas(large city, middle city, and rural area) and they were individually interviewed in March, 1994. The results of study showed that the degrees of stress measured by GHQ-60 were statistically significant in the residents' area, age, sex variables: (a) the residents in middle city among three areas had the highest level of stress; (b) the residents who were more than 60 in age had the highest level of stress: (c) the female residents had more stress than male residents, (d) particularly, the residents who were more than 60 years old in the middle city had the highest level of stress. Further, the results of factor analysis showed that there were three factors of social dysfunction, depression and anxiety and psychosomatic symptom. The social dysfunction factor was statistically significant in both age and resident area variables. The depression and anxiety factor was statistically significant in the residents' area, age, sex variables. The psychosomatic symptom factor was statistically significant in both age and sex variables. The study suggested that they should give a special attention to solve the old people's stress because stress was closely related to residents' age.

Prediction of fatigue duration is attainable from the analysis of the growth rate of the fatigue crack, and the property of the fatigue crack growth is determined by the calculation of the stress intensity factor. And the evaluation of the stress intensity factor, K comes from the stress analysis of the vicinity of crack tip of the continuum. This study describes a simple method to decide the stress intensity factor for the small crack at the sharp edge notches. The proposed method is based on the similarities between elastic stress fields of the notch tip described by two parameters, the stress concentration factor K, the radius of arc of the notch. And it is applicable to the analysis of the semi-elliptical penetration cracks and the edge notches.

The purpose of this research was to delineate the effect of maternal parenting stress and verbal abuse on emotional maladjustment behaviors in children. The sample consisted of 542 pairs of fifth/sixth graders and seventh/eighth graders, and their mothers. The major findings of the research were as follows: First, looking at the correlation between the mother's age/education level and the maternal parenting stress level, the maternal parenting stress level factor showed differences correlating to the mother's education level. Second, looking at the correlation between the mother's age/education level and the verbal abuse, the verbal abuse factor showed differences correlating to the mother's age/education level. Third, looking at the correlation between the maternal parenting stress level and the verbal abuse, the verbal abuse factor showed differences correlating to the maternal parenting stress level. Forth, the result of multiple regression analysis on the effects of the maternal parenting stress and verbal abuse on the children's emotional maladjustment behaviors indicated that verbal abuse was the significant contributing factor.

The plant-specific NAC transcription factors control various biological processes, including plant development and stress responses. We have isolated an ANAC032 gene, one of the NAC transcription factor family, which was highly activated by multi-abiotic stresses, including high salt and drought in Arabidopsis. Here, we generated transgenic plants constitutively expressing ANAC032 and its knockout to identify the functional roles of ANAC032 in Arabidopsis under abiotic stress responses. The ANAC032-overexpressing plants showed enhanced tolerance to salinity and drought stresses. The anac032 knockout mutants were observed no significant changes under the high salt and drought conditions. We also monitored the expression of high salt and drought stress-responsive genes in the ANAC032 transgenic plants and anac032 mutant. The ANAC032 overexpression upregulated the expression of stress-responsive genes, RD29A and ERD10, under the stresses. Thus, our data identify that transcription factor ANAC032 plays as an enhancer for salinity and drought tolerance through the upregulation of stress-responsive genes and provides useful genetic traits for generating multi-abiotic stress-tolerant forage crops.

Purpose: This study analyzed domestic articles that studied job-stress of nurses using Meta Analysis to evaluate the responses resulted from job-stress and the factors affecting them. Method: To conduct this study, data were collected primarily from database of "richis" and additionally from 8 nursing journals and 5 theses for a degree on job-stress of clinical nurses. Result: As a result of Meta Analysis casual factor of job-stress, the result represented that two reasons; personal factor was the age, occupational factor were ward, duration of employment and position. By the result of analysis of effect of job-stress, satisfaction of the job, exhaustion, health status and immersion of the job were strongly related to job-stress. According to the general solution against job-stress that referred from job-stress related theses, there are several; Imagination Therapy, Assertive Training and Value Clarification Training could bring significant result. Conclusion: This study showed that because job-stress of clinical nurses had nothing to do with personal factors, job-stress management plans for nurses are needed to focus on occupational factors. Also the study suggested that various coping skills that proved to be effective are needed to be used to relieve job-stress and that's responses on nurses.

Photoelastic experiment has been used to analyze stress of structure and stress in the vicinity of crack tip etc.. Model experiment such as photoelastic experiment has been restricted by problem of residual stress in the photoelastic model material. They are generated by molding, cutting and time effects etc.. They produce some errors in the results of photoelastic experiment data. In this paper, stress optic law considering residual stress already developed by authors was applied to the stress concentration problem and fracture mechanics. Although the specimen was bad with residual stress, we could obtain good results by using the stress optic law considering residual stress. It was found that the stress optic law of photoelastic experiment could be applied to the stress analysis of bimaterial.

Purpose: This study developed a scale of nurses' stress and examined the validity and reliability of the scale. Methods: The scale was developed according to DeVellis' scale development procedure. Based on the Nursing Work Environment Stress model and the results of focus group interviews, 43 preliminary items were generated. A survey was conducted with 208 clinical nurses to test the psychometric properties of the scale. Both exploratory factor analysis and confirmatory factor analysis were employed to figure out and confirm the scale's theoretical structure statistically. In addition, content, convergent, and discriminative validity were evaluated and Cronbach's α was calculated to test internal reliability. Results: The final scale consisted of 19 items and verified four-factor structures. The structure of the scale was confirmed using confirmatory factor analysis, and it showed moderate correlations with the Copenhagen Burnout Inventory and Korean Nurses Occupational Stress Scale. Cronbach's α was .87. Conclusion: A scale of nurses' stress to nursing work was developed to embrace a wide range of nurses' psychological responses to nursing work based on the theoretical model.

A model is constructed to evaluate the stress intensity factors for a center crack subjected to anti-symmetric loading in a layered material. A Fredholm integral equation is derived using the Fourier integral transform method. The integral equation is numerically analyzed to evaluate the effects of stress intensity factor on the shear modulus, Poisson's ratio and crack length to layer thickness. In case of the isotropic homogeneous material, the values of stress intensity factor derived in the present study agree with the previous solutions.

Many researchers have dealt with the problems of fracture mechanics. Generally, these researches are concerned with crack in isotropic material without other micro defects. Actual structure, however, may contain micro defects as well as crack in manufacture processing or operation. If it contains mi defects near a crack, some different characteristics will be appear in fracture behaviors of the crack. This study examines the effect of the micro defect on stress intensity factor of center slant crack rectangular plate subjected to uniform uniaxial tensile stress. In this study, boundary element method(BEM) is used for analysis in stress intensity factor(SIF).
