This study was aimed at investigating the relationship of stress perception and psychopathology with biological variables such as systolic and diastolic blood pressure. serum total cholesterol high density lipoprotein and triglyceride in 50 adult patients with essential hypertension and 50 normotensive individuals. Both of the groups were matched to each other regarding age, sex, the level of education and BMI(body mass index). Stress perception and psychopathology between the two groups were compared using GARS and SCL-90-R scales. Biological variables such as blood pressure(systolic. diastolic), serum total cholesterol, high density lipoprotein and triglyceride were measured in all the subjects. The results were as follows ; 1) Hypertensive patients scored significantly higher than normotensive individuals in stress perception related to unusual happenings, change or no change in routine and overall global area, respectively. 2) Regarding psychopathology, hypertensive patients scored significantly higher than normotensive individuals in depression. hostility and interpersonal sensitivity. respectively. 3) Systolic blood pressure had a significantly positive correlation with scores of stress perception related to sickness and injury, and change or no change in routine, respectively. Diastolic blood pressure had a significantly positive correlation with scores of stress perception related to change or no change in routine. 4) In hypertensive patients. the level of serum total cholesterol had a significantly positive correlation with scores of stress perception related to unusual happenings. However, the level of serum triglyceride had a significantly negative correlation with scores of stress perception related to changes in relationships, sickness or injury, and change or no chang in routine. 5) There were no significant correlations between scores of stress perception and biological factors in the normotensive group. 6) The level of serum triglyceride correlated negatively with phobic anxiety in hypertensive group. whereas it correlated positively with PSDI in normotensive group. In conclusion, these results suggest that hypertensive patients have higher level of stress perception and psychopathology than normal individuals. In hypertensive patients, their stress perception is suggested to be correlated with serum cholesterol.

Purpose: This study determined the level of stress and type of coping style of spouses with high-risk pregnant women. Methods: Subjects were 102 spouses with high-risk pregnant women at 6 hospitals in Seoul and Gyeonggi province from January to August, 2009. The tools for this study were stress scale and coping scale. The data were analyzed by t-test, ANOVA, Scheffe's test and Pearson's correlation coefficient. Results: The average score of subjects stress was 2.18 and coping score was 2.46 point out of 4.00. The highest score of stress categories was 2.44 point in emotional problems and the lowest score was 1.72 in communication and support resources. The stress level was significant differences according to length of marriage, number of hospital visits, satisfaction with marriage relationship, hospitalization days and gestational age respectively. Spouses tended to use an active coping style (2.60) rather than a passive coping style (2.31). There were significant differences according to mother's age and gestational age in active coping and educational level in passive coping. Conclusion: Considering the level of stress coping style and characteristics of high-risk pregnant women's spouses, a nursing intervention should be provided to help them alleviate stress and to encourage active coping.

This study empirically examines how much effect levels of fatigue and stress of a construction worker have on disaster risks from the perspective of human factors concerning construction disaster risks. To achieve the purpose of this study, a survey was conducted with respect to construction workers working at large construction sites within the metropolitan area. The retrieved survey data were analyzed by using the statistical software programs, SPSS 18.0 and AMOS 8.0. The results of this study do not definitively lead to the conclusion that the level of fatigue or stress of construction workers result in disaster risks. However, it does show that the results vary depending upon the individual approach and treatment of stress and fatigue. In particular, this study revealed that disaster risk levels could increase through unsafe behavior intentions which were established as a mediator variable. Also, with respect to unsafe behavior intentions of construction workers leading to disaster risks, when examining the results that the level of mental fatigue, occupational stress and social-psychological stress of construction workers had a greater significant effect than the level of physical fatigue, this study demonstrates the importance of psychological and mental issues that could be easily overlooked with respect manual labor workers.

The purpose of this study was to find out the causal relationship between perceptual level of stress and health state according to Korean constitutions and to analyze that effect on the Korean constitution's health state. Subjects of this study were 87 out patient department of constitution at Kyung-Hee Oriental Medicine Hospital. Data were collected by using interview with Questionaire during 6 months from Feb. 2 to June 31, 1991. The Measurement tools used by this researcher were Go's The Questionaire of Identify about constitution, Lee's stress scale and Go's modified Cornell Medical Index which were approved it's reliability and validity. All of the questionaires of were used after pre- test. For the purposes of the study, the collected data were analyzed by frequency, t-test, ANOVA and Pearson correlation. And then this research's issue was tested by SAS program's ANCOVA. The findings of this study was summarized as follow. 1. There was significantly differences in stress perceptual level in Korean constitution. (F=9.68, P=.000). The So Em In (小陰人) were higher than the other constitution on stress perceptional level. 2. In health state, there was significantly difference among Korean constitution. (F=6.654, P=.002). Also the So Em In (小陰人) was lower than the other constitution at health state. Therefore, it was considerate that So Em In (小陰人) was higher perceptual level of stress than the other constitution and the resulting poor health state. 3. Stressful perception was effected on the health state, as a result inverted correlation was constructed between stress perception and health state. (r=-.6034, P=.0001) 4. After exclusion of stress perceptual level, each of the Korean Constitution's health state was not difference (F=1.01, P=.37). It was mean that differences of the Korean Constitution's perceptual level of stress effected on the health state. Bacause So Em In (小陰人) had higher perceptual level of stress than other constitution (F=9.687, P=.000), in proportion to that one's health state was poor. From the results of this study, it could be concluded that the higher stress perceptual level according to Korean constitution, the poorer health state. Further study in this area needs to be consideration that in order to coping with stress, researcher grope for quality nursing intervention with more accurative assessment about Korean constitution.

Purpose: The purpose of this study is to investigate the effects of relaxation on stress and blood pressure of the college students induced by a cognitive distress game. Methods: The subjects for this research were 18 individuals whose stress index scores were below 4.0 (Asan city). The 18 subjects were divided into two, 9 students were assigned to the experimental group and the other 9 students to the control group randomly. Survey was used to gather data to recognize general characteristics and the level of stress and blood pressure were measured before and after cognitive distress game and relaxation. The gathered data were analyzed with frequency, $X^2$-test, Wilcoxon signed ranks test and Mann Whitney U test using SPSS 14.0 program. Results: Both level of stress and blood pressure displayed a statistically significant difference pre and post cognitive distress game. Relaxation had a statistically significant effect on level of stress. Relaxation, however, did not have statistically significant effect on blood pressure. Conclusion: The above results suggest that while relaxation was effective in reducing level of stress for college students, and therefore recommendable as a means to deal with stress. However, to investigate the effects on physiological index such as blood pressure, further research is needed.

Objectives: We aim to investigate association between health behavior, interpersonal/organizational environment and job stress among government officials. Methods: Through health examination and a survey, this cross sectional study investigated 543 government officials working at Central Government Complex in Seoul, Korea. Health behaviors included alcohol drinking, smoking, moderate exercise and food frequency. Interpersonal environment was measured by health behavior practices of significant others and social support for health promotion. And the measures of organizational environment included facilities for exercise, health related norms and health supportive organizational systems. Job stress was assessed by short version of Korean Occupational Stress Scale(KOSS). Results: The level of job stress among female officials was higher than that of male officials. Multivariate logistic model suggested that higher job stress in male officials was significantly associated with lower position(OR=0.267, p<.01) less grain intake(OR=0.642, p<.05), lower level of social support(OR=0.810, p<.01) and abdominal obesity(OR=2.407, p<.05). On the contrary, female officials' stress level was negatively associated with healthy organizational environment(OR=0.725, p<.05). Conclusions: It is suggested that addressing job stress require tailoring intervention by gender characteristics and integration of interpersonal and organizational level approaches.

Crane operators usually work with their necks bent forward in a seating position for a long period. They have complained of their musculoskeletal stress at their necks. The objective of this study was to find the level of stress at the neck when crane operators bend their neck forward during their work. Experiments were conducted in the laboratory where subjects bent their necks forward for 1 minute and took a rest for 0.5 minute and repeated this performance for 60 minutes. Subjective evaluation using Borg's CR-10 scale and electromyography (EMG) were used to check the level of the stress at the neck. Subjects reported that the level of pain at the end of 60 min. experiment was close to the extreme pain(level 8.95). The EMG level(amplitude) increased 80% on the average and the center frequency of EMG shifted to the lower frequency level which indicated fatigue of neck muscles. Thus, it was found that there is quite much neck stress for crane operators when they maintain their neck posture of bending forward for a long time during their work. This information will be a basis in searching for an intervention measure for the crane operators' neck stress.

Objectives: The purpose of this study was to investigate the relationship between the level of subjective stress recognition and oral symptom experiences including toothache, gum diseases, and oral soft tissue diseases in the Korean adolescents. Methods: The subjects were 68,043 adolescents recruited using a web-based survey, National Korean Youth Risk Behavior in 2015 by the Korean Center for Disease Control. For statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to determine the factors associated with general characteristics, health behaviors, oral health behaviors, and level of subjective stress recognition. Finally, to investigate the relationship between the level of subjective stress recognition and oral symptom experiences, logistic regression analysis was performed. Results: Toothache related subjective stress recognition level was significantly higher in the moderate group with the score of 1.59 (95% CI; 1.49-1.68), and was greater in the high group with 2.38 (95% CI; 2.24-2.53) compared to the low group. Gum disease related subjective stress recognition level was significantly higher in the moderate group with 1.41 (95% CI; 1.32-1.51), and was greater in the high group with 1.99 (95% CI; 1.86-2.13). Oral soft tissue disease related subjective stress recognition level was significantly higher in the moderate group with 1.59 (95% CI; 1.45-1.74), and was greater in the high group with 2.55 (95% CI; 2.33-2.79). Bad breath related subjective stress recognition level was significantly higher in the moderate group with 1.48 (95% CI; 1.39-1.57), and was greater in the high group with 2.10 (95% CI; 1.97-2.25). Conclusions: Higher subjective stress recognition level was found to affect the oral symptoms experienced. Therefore, the stress management plan should be prepared through the cause identification of the main stress in the adolescents. Practical and systematic education is needed for oral health management in the schools.

Stress relaxation tests have been performed under five different tensile strain levels and five different bending strain levels. Three different theoretical models have been developed based on four-element Burger's model, viscoelastic theory and viscous-viscoelastic theory. Experimental data were used to obtain parameters of the models and to verify accuracy of the models. Among the three theoretical models developed in this study, three-integral model (Model 3) based on viscous-viscoelastic theory showed the most exact estimations of stress relaxation under both tensile and bending strains and their correlation coefficients were greater than 0.99 for all the strain levels. Model 1 showed little initial stress relaxation. Model 2 showed excessive initial relaxation and, then, no relaxation after about 20 minute of strain application. Stress retention under strain decreased as strain increased, which means increased stress relaxation as strain increases. When the strain level was less than proportional limit, the effect of strain level on stress relaxation was not clearly shown. However, this effect was increased as strain level increased when strain level was greater than proportional limit.
