Background: This study was carried out to assess psychosocial stress, job stress and mental health status of ship-building male workers and to examine the relationship among psychosocial stress, job stress, mental health status and socio-demographic characteristics. Material & method: The subjects were questioned about: demographic factors, marital status, education, personal history, alcohol intake, smoking, and physical activity, while their psychosocial stress, job stress and mental health status were assessed using Psychological Well-being Index (PWI), Korean Occupational Stress Scale (KOSS) and Symptom Checklist 90-Revision (SCL-90-R). Statistical analyses were used to examine the relationship among psychosocial stress, job stress, mental health status, and socio-demographic characteristics. Result: One hundred nineteen male workers were included. Young age group and unmarried group had high scores of psychosocial stress and job stress. Simple correlation among KOSS scores, PWI scores and SCL-90-R were statistically significant differences(0.38 ≤ r ≤ 0.915, P<0.01). Odds ratio of multiple logistic regression analysis of high risk of psychosocial stress were physical discomfort 4.28, young age group 2.40 and high job stress 2.39. Conclusion: Based on this study result, it could be concluded that physical discomfort, young age group and high job stress were important factors in explaining psychosocial stress.

Damascene Cu interconnects show significant differences in both microstructural and stress behavior compared to those of the Al interconnects patterned using the etching process. Thermal stresses build up during the successive thermal cycles due to the differences in the coefficients of thermal expansion (CTE`s) of the component materials. Other than thermal stresses, growth stresses that are originated from grain growth develop in damascene Cu interconnects as well. In this study, the line width dependence of stress in damascene Cu was examined experimentally as well as with a numerical simulation. The stresses of damascene Cu with a width ranging from 0.13 to 2 ㎛ were measured using x-ray diffraction. The measured hydrostatic stress was found to increase with increasing line width, which was not common tendency for Al interconnects. Microstructure analysis using TEM revealed that the grain sizes increased with increasing line dimensions. The larger stress in the interconnect with large dimension is attributed to the larger grain size, which induce higher growth stress in addition to thermal stress. The contribution of the growth and thermal stress of the damascene lines were quantified based on the grain size data utilizing finite element analysis. By this calculation, the line width dependence of hydrostatic stress of damascene Cu was clearly explained. Finally, the effect of growth stress on stress-related reliability is discussed.

Stress-induced Decrease of Granule Cell Proliferation in Adult Rat Hippocampus: Assessment of Granule Cell Proliferation Using High Doses of Bromodeoxyuridine Before and After Restraint Stress

신경호,Sung-Jin Kim,이금주,You-Chan Shin,Song-hyen Choi,Eunju Do,Sangduk Kim,Boe-Gwun Chun,이민수 한국분자세포생물학회 2005 Molecules and cells Vol.19 No.1

Stress is known to inhibit granule cell proliferation in the hippocampus. However, recent studies suggest that the commonly used dose of bromodeoxyuridine (BrdU) is insufficient to label all fractions of granule cells. Fur-thermore, stress-induced changes in BrdU availability may influence the labeling of newly born cells. To investi-gate whether changes in BrdU availability affect meas-urements of stress-induced granule cell proliferation, granule cell proliferation was assessed using injection of high doses of BrdU before and after restraint stress last-ing 1 h. In addition, to determine whether stress-induced changes in plasma corticosterone levels were influenced by the BrdU, time-dependent changes in plasma corticos-terone levels over 2 h after BrdU injection were com-pared with total accumulated plasma corticosterone lev-els [as determined by areas under the curve (AUC)]. Re-straint stress significantly reduced the numbers of BrdU-labeled cells and clusters in the granule cell layer (GCL) of rats that received BrdU after stress, and decreases of similar magnitude were observed when the rats were given BrdU before stress. BrdU injection enhanced the stress-induced plasma corticosterone response, but there was no difference between the mean AUCs of plasma corticosterone levels of animals injected with BrdU be-fore or after stress. These observations suggest that re-straint stress decreases granule cell proliferation, and that this may be influenced by the extent and duration of plasma corticosterone increases rather than by changes in the availability of BrdU.

Stress mindset refers to implicit beliefs about the effects of stress. Although academical interests in stress mindset are growing, we know next to nothing about whether the original stress mindset scale, developed by Crum and colleagues (2013), can be used for working professionals in Korea. To examine whether the same stress mindset scale can be used in Korean adults with different occupations, we recruited college students and working professionals in finance, medicine, and education (N=531) and asked them to complete stress mindset and perceived stress questionnaires. Findings from a confirmatory factor analysis found no evidence for method effects in the original 8-item stress mindset scale. Furthermore, the results indicated that 4-item stress mindset scale, measuring debilitating effects of stress (Stress Mindset-N4), fits data better than the original 8-item scale and 4-item mindset scale, measuring enhancing effects of stress (Stress Mindset-P4). Measurement invariance testing of Stress Mindset-N4 supports configural, metric invarianc, and scalar invariance. Furthermore, the scale scale reliably predicts perceived distress. ‘스트레스=부정적’이라는 인식이 팽배함에도 불구하고 스트레스의 효과성에 대한 개인의 관점은 차이가 있다. 어떤 사람은 스트레스는 무조건 부정적이라고 믿는 반면 어떤 사람은 스트레스를 통해 성장․발달할 수 있다고 믿는다. 이처럼 스트레스의 효과성에 대한 개인의 신념을 스트레스 마인드셋이라 한다. 본 연구에서는 미국인을 대상으로 Crum과 동료들이 개발한(2013) 스트레스 마인드셋 척도가 국내 다양한 직업군에서 사용될 수 있는지를 요인구조, 방법효과, 측정동일성 검증을 통해 살펴보았다. 대학생과 금융, 의학, 교육 분야에 종사하는 성인 531명을 대상으로 자료를 수집하였으며, 연구결과는 다음과 같다. 확인적 요인분석 결과, Crum과 동료들이 제안한 8개 문항으로 구성된 측정모형의 적합도는 양호하지 않았으며, 방법효과를 통제한 모형에서도 적합도가 좋지 않았다. 스트레스의 부정적인 효과성을 측정하는 4문항으로 구성된 도구(Stress Mindset-N4)와 긍정적인 효과성을 측정하는 4문항으로 구성된 도구(Stress Mindset-P4)의 적합도는 양호한 것으로 나타났으며, 그중에서도 Stress Mindset-N4의 적합도가 더 높았다. Stress Mindset-N4와 P4 도구의 직업별 측정동일성 검증에서는 전자는 형태, 요인부하량, 절편 동일성이 지지 되었으며, 후자는 형태, 요인부하량 동일성이 지지 되었다. 더불어 두 도구 모두 지각한 스트레스를 유의하게 예측하였다. 본 연구결과가 가지는 이론적, 실증적 의의를 논의하였다.

A survey was carried out to investigate the relationship between stress level and practice of dietary guidelines of university students. The subjects of this study were 205 students of Chungbuk National University (males = 104, females = 101) and most of the males and the females were in the junior class (48.0%, 43.5%). Smoking rate of the males (36.5%) was higher than that of the females (2.9%) (p<0.001), and the rate of regular exercise of the male (35.5%) was higher than that of the females (21.7%) (p<0.05). As for the total stress score, the females' score (105.4 points) was higher than the males' score (99.2 points) (p<0.05), indicating that the females had more stress than the males. When the stress level was divided into domains, the score of fatigue stress was highest both in the males (3.00) and the females (3.06); the females were higher than the males both in depression stress and frustration stress. As for the score of practice of dietary guidelines, the senior males and females showed higher score when compared to the other students. As for practicing the contents of the dietary guidelines, "exercise at least for 30 minutes a day" showed higher practice in the males than in the females (p<0.05), while "eat less fried food" showed higher practice in the females than in the males (p<0.01). For both the males and the females, the students who took classes associated with food & nutrition showed higher practice of dietary guidelines than those who did not (p<0.05), and the females who drink alcohol showed considerably lower practice of dietary guidelines than the females who do not drink (p<0.05). As for the relationship between stress and practice of dietary guidelines, only depression stress (p<0.05) had negative effects on dietary behavior of the male among the stress sub-factors, while aggression (p<0.001), anger (p<0.05), and depression (p<0.01) stress had negative effects on dietary behavior of the females. In conclusion, stress was indicated to have negative effects on dietary behavior of the university students, suggesting that education on reduction in stress should be included in developing nutrition programs in order for the students to be improved in their dietary behavio desirably.

본 연구는 스트레스 정도에 따른 영양소 섭취와 대사증후군 위험도를 분석하고자 수행되었다. 본 연구는 40~69세 일반인구 집단을 대상으로 실시한 한국인 역학조사 사업 중 농촌기반코호트를 이용하여 진행하였고, 그중 여성을 대상으로 분석하였다. 대상자들은 사회 심리적 건강측정도구(Psy chosocial Well-being Index, PWI)를 기초로 하여 개발된 18문항의 단축형(PWI-SF)의 평균값을 기준으로 0~26점의 저스트레스군과 27점 이상인 고스트레스군으로 분류되었다. 영양 섭취 상태 및 식습관은 반정량식품섭취빈도조사방법(semi-quantitative food frequency questionnaire, SQFFQ)을 이용하여 평가하였다. 고스트레스군 대상자들은 저스트레스군보다 나이, 허리둘레, 혈압이 유의적으로 낮았으며 신장은 유의적으로 높았다. 혈액분석 결과에서는 고스트레스군이 저스트레스군보다 공복혈당, 인슐린 저항성 지수, 중성지방, 동맥경화 지수가 유의적으로 높았다. 영양소섭취를 분석한 결과 고스트레스군 대상자들이 저스트레스군보다 항산화 영양소인 비타민 A, 비타민 C, 비타민 E, 엽산, 아연, 카로틴을 더 적게 섭취하였다. 과일과 채소의 섭취량 또한 고스트레스군이 저스트레스군보다 유의적으로 적었다. 스트레스와 대사증후군 위험의 관계를 살펴본 결과 고스트레스군 대상자들이 저스트레스군보다 대사증후군의 교차비가 유의적으로 높았다. 결과적으로 한국 농촌 여성에서 스트레스가 높을수록 항산화 영양소와 과일 및 채소의 섭취가 적었으며 대사증후군 위험이 증가하는 것으로 나타났다. The aim of the present study was to investigate antioxidant nutrient intake and risk of metabolic syndrome based on stress level in rural Korean women. Subject were participants from the Multi-Rural Communities Cohort Study, which was a part of the Korean Genome and Epidemiology Study. According to scores of the Psychosocial Well-Being Index Short-Form, a total of 10,111 subjects were classified into ‘low stress group (n=8,015)’ from 0 to 26 points and ‘high stress group (n=2,096)’ above 27 points. Data were collected using self-administered questionnaires, anthropometric measurements, and blood chemical analysis. Dietary nutrient consumption was assessed by a semi-quantitative food frequency questionnaire. High stress group showed lower intake of antioxidant nutrients, such as vitamin A, vitamin C, vitamin E, folate, zinc, and carotene compared to the low stress group. Intake of fruits and vegetable was lower in the high stress group compared to the low stress group. Subjects with high stress showed higher risk of hypertension [odd ratio (OR), 95% confidence interval (CI)=1.226 (1.112∼1.351)] and hypertriglyceridemia [OR, 95% CI=1.227 (1.110∼1.356)] than subjects with low stress. High stress group had a significantly greater odds ratio for metabolic syndrome compared with the low stress group [OR, 95% CI=1.216 (1.101∼1.342]). Thus, the present study suggests that high stress might be associated with low intake of antioxidant nutrients and high risk of metabolic syndrome in rural Korean women.

직장인의 스트레스 증상과 대처 관련 변인에 대한 연구: 정서적 지원, 자기효능감, 직무만족도, 직무성취도를 중심으로

박영신,이경란,안자영,이상희 한국문화및사회문제심리학회 2015 한국심리학회지: 문화 및 사회문제 Vol.21 No.3

The main purpose of this research is to examine the relation of variables related to the worker’s stress symptoms and coping. The influence of emotional support(from family, colleague, and boss), self-efficacy (self-regulatory, social, relational, resiliency, and management of work), job-satisfaction, and job-performance on worker’s stress symptoms and coping is analyzed. Participants were 559 teachers (elementary 205, junior high 203, senior high 151; male 132, female 427). The results were as follows: There were no significant differences in stress symptoms and coping among primary, junior and senior high school teachers. On the other hand, there were significant differences in stress symptoms and coping between male and female teachers. Female teachers experienced more stress symptoms than male teachers. At the same time female teachers coped more efficiently in stress situation than male teachers. With emotional support, self-efficacy, job-performance and job-satisfaction as independent variables, the result of multiple regression showed that job-satisfaction has a negative influence on stress symptoms. Positive influences on stress coping was found for resiliency of self-efficacy in case of male teachers, and in case of female teachers resiliency of self-efficacy, emotional support from colleague, job-performance, and emotional support from family. Therefore, regardless of the gender of the teachers, high job-satisfaction decreased stress symptoms and high resiliency of self-efficacy increased efficient stress coping. As for female teachers, not only resiliency of self-efficacy but also emotional support from colleague and family, job-performance contributed to coping with stress. 이 연구에서는 직장인의 스트레스 증상과 대처 관련 변인들 사이의 관계를 분석하는 데 주된 목적이 있다. 이를 위해 정서적 지원(가족, 직장동료, 직장상사), 자기효능감(자기조절, 사회성, 관계, 어려움극복, 업무처리), 직무만족도, 직무성취도가 스트레스 증상 및 대처에 미치는 영향력의 정도를 분석하였다. 분석대상은 교사 559명(초 205, 중 203, 고 151; 남 132, 여 427)이었다. 분석결과, 학교급별로 초, 중, 고등학교 교사는 스트레스 증상과 대처에서 차이가 없었다. 그러나 성별로는 유의한 차이가 있었는데, 여자 교사가 남자 교사보다 스트레스 증상이 높았으나 대처도 더 잘 하였다. 정서적 지원, 자기효능감, 직무성취도, 직무만족도 변인을 투입하여 중다회귀분석 하였을 때, 스트레스 증상에 대해 남녀 교사 모두 직무만족도가 의미 있는 부적인 영향력을 나타내었다. 스트레스 대처에 대해서는 남자 교사 경우에 어려움극복효능감이, 여자 교사 경우에 어려움극복효능감, 동료의 정서적 지원, 직무성취도, 가족의 정서적 지원이 의미 있는 정적인 영향력을 나타내었다. 따라서 남녀 교사 모두 높은 직무만족도는 스트레스 증상을 완화하는데 기여하는 것으로 확인되었다. 또한 남녀 교사 모두 높은 어려움극복효능감은 스트레스의 효율적 대처에 기여하였으며, 여자 교사 경우에는 이외에도 동료나 가족의 정서적 지원 및 직무성취도가 스트레스 대처에 도움이 되었다.

Stress is an area of research that has grown and diversified enormously since the early work of W. E. Cannon and Hans Selye. This development has been accompanied by an accelerated and renewed interest in instruments for evaluating stress and related factors. At present,the questionnaire method is the most popular for stress measurement. However, there is no consensus on how to measure stress because of the diverse scope of stress dynamic. There are many different kinds of questionnaires for measuring stress. And these questionnaires are different according to the various aspects, such as external stressors, individual’s sense of control or coping, susceptibility, personality type, and subjective symptoms. Each questionnaire has its own drawbacks as a tool for measuring stress. Therefore choosing the appropriate instruments for evaluating stress objectively is a basic and crucial step for developing effective stress reduction strategies. Another important problem is that many of the questionnaires for measuring stress currently used in the field lack an appropriate cross-cultural adaptation process for the translated version and sufficient evidence of validity and reliability.
