A computer software was developed for predictions of fatigue crack initiation life of notched members under variable loadings. The software was constructed based on a new fatigue life prediction method utilizing modified .epsilon.-N curves, which can account for the stress interaction effect. The effect of mean plastic strain on low-cycle fatigue life was also incorporated in the software. The software can be utilized for the first step approximation when fundamental data of material fatigue properties are not available.

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.

The purpose of this study is to classify the stress into groups and analyze their differences in self-consciousness, and appearance management behavior. Questionnaires were administered to 377 middle and high school girls living in Deagu metropolitan City. Frequency, factor analysis, reliability analysis, cluster analysis, ANOVA, Duncant-test, and t-test are all used for data analysis. Our findings show that stress developed due to several reasons: the categories are as follows into grades-related low stress, exam-related high stress, and society-related high stress. For the purposes of our study, we labeled self-consciousness as a combination of being socially and privately self-consciousness and showing signs of social anxiety. Appearance management behavior deals with esthetic plastic surgery, clothing harmony, weight management, hair management, health care, skin care, and meal management. Stress shows a significant correlation with the sub-variable self-consciousness and appearance management behavior. The groups show a significant difference in the self-consciousness, and appearance management behavior. There is also a significant difference among stress, self-consciousness and appearance management behavior by grade. The students in seemed to recognize that their appearance can be improved by dressing up and managing their outwardly appearance. Teachers should educate students to have the variety of views on the meaning of beauty. In addition, schools need to develop programs to educate student about appearances, as the student's interests differ due to the stress type of the adolescent.

The purpose of this study was to gain an understanding about urban housewives' stress in family financial management, their coping strategies, and their sense of economic well-being, which will eventually provide some baseline data for policy development. The findings of this study are summarized in the following. First, the mean score of the level of financial management-related stress among urban housewives was 2.61 when the maximum level was set at 5. In order to overcome the stress from financial management, housewives utilized various strategies, such as purchasing management, financial planning, financial information gathering, getting a loan, and delaying payments. The average level of economic well-being among urban housewives was 2.82 when the maximum level was 5. Second, among socio-demographic factors, the family's monthly income and the husband's job satisfaction were the two most significant factors that affected the level of financial management stress among housewives. Third, there was a difference in employing coping strategies according to the level of stress. The group with a higher level of financial stress employed more coping strategies than the group with, a lower level of stress. Fourth, there were differences in the level of economic well-being, depending on the types of coping strategies employed. Fifth, the results from regression analyses, which were conducted to determine the relative explanatory power of different independent variable groups including subjective factors, financial management stress, and coping strategies, showed that socio-demographic and objective economic factors significantly affected economic well-being.

Purpose - In this study, among the various stresses experienced by single-family senior citizens, we will focus on economic and financial stress and help to comprehend it generally, examine the differences in economic and financial stress and coping behaviors caused by the background variables in the aged group, and verify the variables that affect economic and financial stress, response behavior, and life satisfaction. Research design, data, and methodology - First of all, frequency analysis and technical statistics were conducted to identify the general characteristics of the elderly (characteristics of demographic sociology, social relationships) and the satisfaction level of life. Secondly, Hierarchical Multiple Regression Analysis was conducted to analyse influential factors on life satisfaction. Results - looking at the demographic characteristics of the elderly showed that in case the spouse exists, the level of satisfaction in life was shown to be higher. Next, looking at the characteristics of economic stress showed that the lower the economic stress was, the higher the satisfaction level of life was shown. Conclusions - Since stress has been identified as the most influential variable in life satisfaction through this study, we believe that economic and financial stress should be studied together as a parameter to find out which factors influence life satisfaction, or studies to reduce stresses for experts and senior party members altogether is also needed.

Individuals have been under more stress since the COVID-19 pandemic began than they were before the pandemic. While social support is a known stress buffer among the general population, its impact on stress among vulnerable populations, such as immigrants and those living in rural areas, has received little attention in the context of South Korea. Accordingly, we examined the relationship between different types of social support and COVID-19 stress among young adult immigrants based on where they live (rural vs. urban). We conducted a survey of 300 young adult immigrants aged 25-34 years and analyzed the results. The dependent variable was COVID-19 stress, and the independent variables were four types of social support: emotional, appraisal, instrumental, and informational. We discovered that young adult immigrants in rural areas perceived higher-level social supportin all aspects compared with those in urban areas. Furthermore, social support was not related to COVID-19 stress in urban areas, while appraisal support was positively and informational support was negatively related to COVID-19 stress in rural areas. Our findings suggest that a contextualized understanding of social support is critical to understanding COVID-related stress during the COVID-19 pandemic.

Purpose: The present study investigates if the type of organizational culture influences the level of job-related stress. This study is significant because creating the need to explore the concept to become more informed on the best practices to promote and foster a positive culture that prioritizes workers, it could result in a healthier workforce, improved organizational performance, and success. Research design, data and methodology: Examining previous studies by other researchers was the primary research tool for this study. The organized approach of gathering data and assessing related work was vital in developing a fundamental basis for advancing knowledge on this concept while enhancing theory development and drawing more informed conclusion. Results: These four types, including the clan, adhocracy, hierarchical, and market cultures, contribute significantly in revealing four associations between the two variables, including (i) supportive culture and reduced stress, (ii) high pressure and increased stress, (iii)autonomous culture and variable stress levels, and (iv) open culture and low-stress levels. Conclusions: The literature affirms a multifaceted link between employee workplace stress and organizational culture type. The findings show that these cultures are crucial in influencing the level of stress among employees. All four types were hypothesized to have a significant relationship with job stress.

This study presents thickness optimization for the pressure vessel domes subject to internal pressure and axial force simultaneously. The considered typical pressure vessel domes are ellipsoidal and tori-spherical domes with skirt and nozzle part. These pressure vessel domes under loading have higher stress concentration on geometric discontinuity parts. Therefore, thickness optimization of axi-symmetric pressure vessel domes is essentially concerned on minimizing this stress concentration. The objective function is minimization of weight of pressure vessel dome. The design variable is thickness of dome and cylinder. Considered constraint is Von Mises equivalent stress. In the optimization procedure, ANSYS code is used. The equivalent and hoop stress of original shape domes are compared with those of optimal shape domes. And optimal thicknesses for pressure vessel domes are presented.

The current study is a part of series of research about the evaluation method of the unbonded tendon stress in prestressed concrete member at flexural failure. As the experimental study, a test program with 14 beams and slabs was planed to identify the contribution of each important variable. The variables are (1) the effective prestress, (2) the concrete strength, (3) the amount of tendons (4) the amount of bonded reinforcements, (5) the loading type, (6) the span/depth ratio. It was found that the tendon stress increment decreases as the effective prestress increases. Also, the contributions of concrete strength, amount of tendons, bonded reinforcements, and loading type were observed to affect on tendon stresses. However, the tendon stress increments were minimal at high values of span/depth in contrast with the ACI Code.

In case that a general cusp-crack shaped inclusion expressed in a polynominal form of conformal mapping function exists in a two dimensional elastic body under uniform heat flow, the complex potential and thermal stress intensity factors are derived. Two thermal boundary conditions are considered, one an insulated rigid inclusion and the other a rigid inclusion with fixed boundary temperature. The previous solutions of the thermal stress intensity factors for symmetrical airfoil and lip type rigid inclusions are obtained from the general solution of the thermal stress intensity factors.
