The purpose of this study was to identify the effects of gene expression of endoplasmic reticulum (ER) stress in skeletal muscle and adipose tissue on acute exhaustive exercise. Thirty-five Sparague Dawley male rats were divided into a control group (CON, n = 7) and a exhaustive exercise group (n = 28), immediately after exhaustive exercise group (n = 7), after 30 minutes exhaustive exercise group (n = 7), after 60 minutes exhaustive exercise group (n = 7), after 180 minutes exhaustive exercise group (n = 7). As a result, changes in the composition of the blood serum triglyceride concentration increased significantly in immediately after exhaustive exercise group, On the contrary, blood glucose showed a significantly decreased (p < .05). Homeostasis of energy metabolism due to exhaustive exercise as a result of the mechanism of action of skeletal muscle in the glycogenolysis and absorption, which indicates that the process of means. On the other hand, a result of examining changes in endoplasmic reticulum stress-related proteins in skeletal muscle and adipose tissue, JNK1 except in skeletal muscle BiP, ATF4, CHOP, GRP78 mRNA increased significantly immediately after exercise, and after 30 minutes returned to normal levels that could be confirmed (p < .05). BiP mRNA in adipose tissue show a similar pattern and skeletal muscle increased significantly immediately after exercise, but other changes in the specificity of the endoplasmic reticulum stress-related proteins also did not appear. In conclusion, Exercise applies and exercise training duration and exercise intensity as well as research on the interaction of the endoplasmic reticulum stress-related genes should be study continuously, to be more clear.

Objectives : The purpose of this study was to examine the relationship of stress, health problems, absenteeism, productivity and presenteeism in Korean and Japanese workers. Methods : Data was collected from April 12 to July 18, 2008 in both countries. The content of questionnaires was demographic factors, stress and the Stanford Presenteeism Scale. Korean data from 810 workers was collected and Japanese data from 822 workers was collected by same questionnaires of both language. SPSS 12.0 and AMOS 5.0 programs were used for data analysis. Results : The major health problems in relation to the impaired presenteeism of Korean workers were dizziness, allergy, headache and dysmenorrhea, and for Japanese workers were arthritis, depression, and diabetes mellitus. Impaired presenteeism was increasing when the numbers of health problems were increasing in both countries. In Korean workers, job-related stress and the numbers of health problems directly affected presenteeism. In Japanese workers, job-related stress, life-related stress and the numbers of health problems directly affected presenteeism. Conclusions : Health managers should include physical and psychological health management programs for presenteeism control in workplace. They can obtain a greater benefit through both programs.

Purpose: The purpose of this study was to test the physical and psychological-emotional status according to type of personality of female college student smokers and to provide baseline data for smoking cessation education programs for women. Method: The data were collected from May to June. 2002. The subjects were 119 female students who smoked. The data were analyzed using SPSS/PC. Results : The results are as follows 1. There were 91 (76.5%) A type and 28 (23.5%) B Type personality types, indicating that female student smokers were more frequently type A rather than type B. 2. Perceived health status by personality type indicated that those with type B ($27.71{\pm}4.67$) perceived higher health status than those with type A ($26.53{\pm}4.60$) but the result was not statistically significant (p = 237). 3. Perceived stress by personality type indicated that those with type B ($83.71{\pm}13.13$) perceived more stress than those with type A ($70.52{\pm}12.35$). 4. Differences between depression by personality type indicated that those with type B ($47.21{\pm}8.53$) perceived more stress than those with type A ($45.42{\pm}7.32$) but this was not statistically significant (p = .277). 5. There were significant negative correlations between perceived health status and stress (r=-0.300. p<0.004), depression and perceived health status (r=-.456. p<0.000). There was significant positive correlation between stress and depression (r= .700, p<0.000). 6. There was no significant difference between perceived health status, stress, or depression according to general characteristics. Conclusion: According to the results, researchers should continually identify women's smoking behavior included various physical and psychological variables related to women's health. In addition, programs for improving physical and psychological health should be designed and operated to decrease the perception of stress and to increase the perception of health motivation for women smokers.

Purpose : This study was conducted to identify the common characteristics of older persons with sarcopenia and to explore the relationship between gait, balance, and stress using an integrated assessment tool. Methods : In this study, 95 people aged 65 years or older were screened using the sarcopenia diagnostic evaluation algorithm presented by the Asian Working Group for Sarcopenia in 2019. Skeletal muscle index, grip strength, and short physical performance battery were used as sarcopenia evaluation measurements. Based on the results of this evaluation, participants were grouped into the 'non-sarcopenia group' (41 participants) or the 'sarcopenia group' (54 participants). Participants underwent further assessment using an integrated evaluation tool capable of measuring gait, balance, and stress. Gait ability was evaluated using the timed up and go test, and balance ability was evaluated using the berg balance scale. And the stress of the last month was measured by modifying the stress index developed by a Korean researcher. Collected data were statistically analyzed using the independent t-test and Mann Whitney-U test. Results : The sarcopenia group and the non-sarcopenia group showed significant differences in all elements of the sarcopenia diagnostic evaluation. There were significant differences in all three integrated evaluation tools. For the evaluation of walking ability, the time measured in the timed up and go test was longer in the sarcopenia group, the berg balance scale score for the evaluation of balance ability was lower in the sarcopenia group, and the stress index was higher in the sarcopenia group. Conclusion : Through sarcopenia analysis using an integrated evaluation tool, it was confirmed that sarcopenia is closely related to decreased walking ability, poor balance, and increased stress. We recommend using this tool to reduce the risk of sarcopenia progression and stress exposure through the planning and implementation of an exercise program for sarcopenia prevention.

Objective: The purpose of this study was to investigate the job stress factors of mobile communication network construction workers using survey based on 'Job stress factors evaluation tool for Koreans' that was developed by KOSHA in 2003. Background: Due to the rapid growth of penetration rate of smartphone, the necessity of LTE service changing from 3G network was brought up. The demand of LTE network construction in a short period of time leads to the aggravation of the job stress of mobile communication network construction workers. Method: Two hundred and fifty workers who were in the mobile communication network industry participated in this study, and among them 206 responses were analyzed for this study due to the unreliability and insincerity of responses. The eight job stress factors which are physical environment, job demand, job autonomy, relation conflict, job instability, organizational system, inadequate compensation, workplace culture were analyzed. Results: The job stress factors of mobile communication network construction workers were compared to those of other industry workers, and other work related characteristics were analyzed. The results showed that the stress level of a physical environment and job requirement were relatively higher than those of manufacturing industry workers, meaning that mobile communication network construction workers have rough working conditions and increased amount of work due to the demand of LTE network construction. The stress level of physical environment for outdoor job workers was relatively higher than that of indoor job workers. With the analytical result for level of job satisfaction, significant difference was observed (p <0.05) with every factor, and the job stress was found the highest with those not satisfied with every factor Conclusion: From the results of this study, the work loss due to the job stress could be prevented, and accurate stress factors could be removed at the workplace. Application: The results of this study may not represent the whole mobile network construction workers, the effort for job stress management is needed to improve the work efficiency and the workers' quality of life.

Purpose: The purpose of this study was to identify the causal relationship between workplace stress and working posture and the development of work-related neck pain in office workers. Methods: The study participants included 62 office workers who had not experienced neck pain in the previous 12 months. A battery of measures to evaluate potential workplace risk factors in an office setting were conducted at baseline, and the 12-month incidence of work-related neck pain was reported via monthly questionnaires. Survival analysis was used to evaluate the longitudinal relationship between the workplace risk factors and the development of work-related neck pain. Results: The incidence of work-related neck pain was 1.91 (95% CI: 1.06-3.45) per 100 person months. The incidence of neck pain was predicted to be less likely to happen when workers had a more upright thorax posture during computer work (hazard ratio, 0.94; 95% CI: 0.89-0.99). However, stress may deteriorate the preventative effects of other risk factors on neck pain and showed a positive relationship with episodes of neck pain (hazard ratio, 1.37; 95% CI: 1.03-1.84). Conclusion: Understanding the psychophysiological effects of neck pain may explain the development of neck pain in office workers. Our interest in prevention plans and treatments should therefore involve a multifactorial pathology of neck pain in the workplace.

Physical properties of water, such as dielectric constant and ionic product, significantly vary with the density of water. In the supercritical conditions, since density of water widely varies with pressure, pressure has a strong influence on physical properties of water. Dielectric constant represents a character of water as a solvent, which determines solubility of an inorganic compound including metal oxides. Dissociation equilibrium of an acid is also strongly dependent on water density. Dissociation constant of acid rises with increased density of water, resulting in drop of pH. Density of water and the density-related physical properties of water, therefore, are the major governing factors of corrosion and environmentally assisted cracking of metals in supercritical aqueous solutions. This paper discusses importance of "physical properties of water" in understanding corrosion and cracking behavior of alloys in supercritical water environments, based on experimental data and estimated solubility of metal oxides. It has been pointed out that the water density can have significant effects on stress corrosion cracking (SCC) susceptibility of metals in supercritical water, when dissolution of metal plays the key role in the cracking phenomena.

Atopic dermatitis is the fastest growing skin disorder among children from infancy to adolescence in Korea. The side-effects of atopic dermatitis not only include physical discomfort, but also psychological trauma which ultimately affects the developmental growth of children. This study was conducted in order to investigate the behavioral characteristics of an atopic dermatitis sufferer. As part of this research, the relative influence of behavioral problems and, self-perceived competence were analyzed in relation to the social competence of an atopic child. In total, 301 atopic and non-atopic children, between 2 and 6 years of age, and their mothers and teachers participated in the study. From this number, 109 children had atopic dermatitis, while 192 children did not. Mothers were asked to complete a parent-report questionnaire that required information on parental stress, according to the scale parenting methodology of Abbdin(1990) and Cho(1999). Teachers were subjected to teacher-report questionnaires which included topics on social competence, socia-emotional assessment and behavioral problems of an atopic child. Furthermore, children also completed questionnaires on self-perceived competence. According to analysis on K-CBCL, ITSEA, social competence, self-perceived competence and parental stress, children with atopic dermatitis showed higher scores in depression/anxiety and depression/withdrawal, compared to children in the normal control group. In relation to parental stress, daily stress, parental role stress, and stress related disease, mothers with atopic dermatitis children exhibited higher scores. In establishing relationships among the related variables, atopic children who demonstrated more social competence were more likely to suffer less from withdrawal, attention problems, and depression/anxiety. Stress related disease in mothers with atopic children was positively related to attention problems of the child. In terms of relative influences, behavioral problems was the most significant variable, accounting for 23% of variance. Lower behavioral problems was positively related to more social competence. In summation, this study investigated the general characteristics of atopic children. In conclusion, atopic children and their mothers had difficulty in dealing with this disease. It is our belief that an atopic child would not only require physical treatment, but also need appropriate psychological care.
