The propose of this study is to examine the economic stresses and coping strategies for elderly households depending on the variables of background, and to analyze the relations between these factors. Elderly households which satisfied the following criteria were recruited for participation: (a) reside in Seoul, or in the metropolitan area (b) live apart from their adult children after retirement and (c) ages over sixty. From September 20th, 2006 to November 30th, 2006, 296 were used for this research. First, the mean score of the economic stress level of elderly households was 2.87 out of 5, and the stress levels of income expenditure and asset debt were intermediate. The mean score of the economic coping strategy was 3.17 out of 5. In order to overcome economic stress, elderly households utilized reducing their expenditure, financial management, and re-employment. The level of elderly households' life satisfaction was 3.29 of 5 and the depression was 3.17 of 5. Second, there was a difference in accordance with the objective economic variables and the degree of the economic stress after the review of the variables of the elderly households and the coping strategy due to economic stress. The result shows that the households which had a low economic status and high economic stress from the objective viewpoint participated in more economic activities. Their reactions were to decrease the overall expenditure through reducing the expenditure rather than to manage the asset effectively through re-employment or to inaugurating a business. Third, I analyzed situational factors, economic stress, and economic coping strategy in order to compare relative contributors to psychological well-being through using regression. At the third phase in the process of analysis, the socio-psychological factors appeared to be significant factors contributing to psychological well-being. Regarding the stress caused by income expenditure increased, when elderly households were more concerned about reducing expenditure and re-employment, their feelings of depression increased.

Objective : This study was to examine the effects of Doin-Angyo program, evidenced by East Asian Medicine literatures, on stress among smoking adolescents. Method : This study was a prospective community trial using a one-group, pretest-posttest design. As an intervention, Doin-Angyo program was implemented for 10 minutes per session, 3 days a week, for 6 weeks to smoking students who attend a Girl's high school. Psychological stress was measured by self-report questionnaire and physiological stress was measured by salivary cortisol. The final sample for the questionnaire included 18 participants. In addition, pre- and post-salivary cortisol levels of 24 adolescents participating in the last session were compared in order to identify the acute effects of Doin-Angyo program in reducing stress. Results : There were no significant differences in overall stress-test results from the comparisons before and after the intervention. However, we found a significant going-down of the stress level(p = .032) in the question, "About School-work" among six sub-category questions. From the salivary cortisol tests in the last session, we found, in comparison with the standard salivary cortisol density level, $0.3{\mu}g/dL$, the density level tended to go down(p = .062) when higher than the standard, and it went up(p = .001) when lower than the standard, after 10 minute session. Conclusion : The results of this pilot study supported the partial effect of Doin-Angyo program in reducing the stress levels. The study protocol and results can be used to elaborate the community trials design aiming to prove the effect of Korean Medicine based health promotion modalities.

This study aimed to systematically review the literature on the stress reduction of meaning-centered therapy (MCT) studies in Korea and to identify the characteristics of MCT for stress reduction. MCT studies aimed at reducing stress symptoms were searched among peer reviewed journal articles and unpublished dissertations until April, 2020. Two independent researchers assessed the risk of bias and the quality of the report using Scottish Intercollegiate Guidelines Network criteria. As a result of searching with 7 databases, 7 studies were finally selected. Seven MCTs were for all age groups, and 5 studies reported MCT was effective in reducing stress symptoms. Both single and combined type interventions were effective in reducing stress symptom, Researchers used the combined MCT more than single MCT program. The study with no significant effect was related to school test stress. There is a need to develop MCTs suitable for school-age youth with test stress in the future.

Objectives: Stress is the cause of several illnesses, in older people, stress may also cause various social problems. The oral health of older adults is closely related to the quality of life, and chewing ability is particularly important for their general health. The purpose of this study was to investigate the relationship between stress, the number of teeth remaining, and the chewing ability, which reflects the oral health status among older adults. Methods: This study evaluated the stress level and chewing ability of adults older than 65 years using the 6th (2014-2015) Korea National Health and Nutrition Examination data. The total number of remaining teeth was determined based on the data of the teeth conditions. Results: There was an association between stress and chewing ability among older adults. The odds ratio of chewing function increased by 2.67 times (crude OR=2.67; 95% CI=1.88-3.79) with increased stress. After adjusting, the odds ratio increased to 2.74 times (adjusted OR=2.74; 95% CI=1.88-3.98). Conclusions: Reducing stress may facilitate effective oral health management and improve the overall quality of life in older adults. The findings of this study may help in the discovery of various approaches s to reducing stress in older adults and provide relevant information for oral health education.

Stress wave propagation plays an important role in many engineering problems for reducing industrial noise and vibrations. In this paper, the dispersion-corrected finite element model is proposed for reducing the dispersion error in simulation of stress wave propagation. At eliminating the numerical dispersion error arising from the numerical simulation of stress wave propagation, numerical dispersion characteristics of the wave equation based finite element model are analyzed and some dispersion control scheme are proposed. The validity of the dispersion correction techniques is demonstrated by comparing the numerical solutions obtained using the present techniques.

A modified low-Reynolds-number Reynolds stress model is developed for the calculation of drag-reducing turbulent flows induced by polymer injection. The results without polymer injection are compared with the results of direct numerical simulation to ensure the validity of the basic model. In case of drag reduction, profiles of mean velocity and Reynolds stress components, in two-dimensional channel flow, obtained with a proper value of viscosity ratio are presented and discussed. Computed mean velocity profile is in very good agreement with experimental data. And, the qualitative behavior of Reynolds stress components with the viscosity ratio is also reasonable.

The results obtained are as follows: 1. Qi promoting-agents(Cypri Rhizama, Auranti pericarpium, Aucklandiae Radix and Bupleuri Radix) showed mildly reducing effect or did not shown the reducing effect against the elevated coritocostereone level induced by the immobilization stress in the mice. 2. Hwangyeonhaedok-Tang, Gungangbuza-Tang, and Soyo-San did not show the reducing effect against the elevated corticostereone level induced by the immobilization stress in the mice. 3. Shihoieokgan-San was effective against the elevated corticosterone level induced by the immobililzation stress at 1g／kg, 3g／kg respectively. Consequently these data proved that Qi pomoting-agents as single herb(Cypri Rhizama, Auranti pericarpium, Aucklandiae Radix and Bupleuri Radix), clearing heat of deficiency type-agent(Soyo-San), warming interior part of the body(Gungangbuza-Tang), clearing heat of excessive type-agent(Hwangyeonhaedok-Tang) have no effect to decrease the elevated corticosterone level in mice exposed to the immobilization stress. Therefore our study revealed that Shihoieokgan-San which has the effects of herbs and formulae mentioned above decreased the elevated corticosterone level in mice exposed to the immobilization stress significantly.

Purpose: This study was conducted to determine if women's depression is influenced by their self esteem, stress, and social support. Methods: This study was a descriptive survey, and data were collected from the November 1 to December 20, 2015 using a self-reported questionnaire. The measurements were SES for self esteem, and CES-D for depression. A total of 165 middle-aged women participated through convenient sampling. Results: There were significant difference in self-esteem according to education level and monthly income. Additionally, there was an inverse correlation between stress and self esteem, as well as a significant strong correlation between self esteem, stress, social support and depression. Finally, multiple regression showed that self-esteem and stress had significant effects on depression, and their explanatory power was ${\Delta}R2(%)=47.9$ (${\Delta}F=66.526$, p<.001), p<.001). Conclusion: This study confirmed that depression was closely related to self-esteem and stress among middle-aged women. Based on these findings, we suggest that the health policies of reducing depression for middle-aged women should focus on reducing stress and reinforcing their self-esteem.

Oxidative damage to mitochondria is a critical mechanism in necrotic or apoptotic cell death induced by many kinds of toxic chemicals. Thioredoxin (Trx) family proteins are known to play protective roles in organisms under oxidative stress through redox reaction by using reducing equivalents of cysteines at a conserved active site, Cys-X-X-Cys. Whereas biological and physiological properties of Trx1 are well characterized, significance of mitochondrial thioredoxin (Trx2) is not well known. Therefore, we addressed physiological role of Trx2 in PC12 cells under oxidative stress. In PC12 cells, transiently overexpressed Trx2 significantly reduced cell death induced by hydrogen peroxide, whereas mutant Trx2, having serine residues instead of two cysteine residues at the active site did not. In addition, stably expressed Trx2 protected PC12 cells from serum deprivation. These results suggest that Trx2 may play defensive roles in PC12 cells by reducing oxidative stress to mitochondria.
