Objective: This study was carried out to examine factors influencing job stress and health promotion behavior of medical doctors, who play the important role for improving people's health. The data were collected from 340 medical doctors working in clinic and hospitals in Daegu using self-administered questionnaires over the period from July 1 to August 15, 2018. Methods: A multiple regression model was used to study the factors influencing job stress and health promotion behavior of medical doctors. Results: This study showed that average job stress level of the subjects was 3.06 out of 5 point. The medical doctors with carrying out surgery and longer working time tend to have higher job stress level compared to other groups without surgery and having short working time. And medical doctors generally do not have good health promotion behavior and average level of practice of health promotion behavior of the subjects was 2.30 out of 5. The groups with high rate of quitting job and working in hospital tend to have lower practice level of health promotion behavior compared to other groups. And it also showed that the groups with higher the job satisfaction rate and vocational aptitude tended to have the higher level of practice of health promotion behavior compared with other groups. Conclusions: Medical doctors tend to have higher job stress level, whereas they have relatively lower health promotion behavior compared with people with other jobs. Thus, strengthening of health education and counselling for medical doctors and improvement of work environment considering job's characteristics is needed. In particular, the education for job stress management and health promotion in regular continuing education program organized by medical doctors's association should be strengthened.

Purpose: This descriptive study aimed to investigate heart rate variability (HRV) according to sex and to elucidate the influence of negative emotion such as levels of stress, anxiety and depression on HRV among Korean college students based on a neurovisceral integration model. Methods: A descriptive study design was used. Eighty-six healthy college students participated in the study. Resting HRV and standing HRV on orthostatic stimulation were measured for 5 minutes during 4-6 p.m. in the afternoon. Levels of stress, anxiety and depression were assessed using the Global assessment of recent stress, State-Trait Anxiety Inventory and Beck Depression Index, respectively. Results: Out of the 86 students, 47 (54.7%) were men and 39 (45.3%) were women. Root mean square of the differences between adjacent RR intervals (RMSSD) and normalized high frequency (nHF) on standing HRV were significantly lower in men than in women (p= .005, p= .019, respectively). Male gender (β= 0.30, p= .013), higher level of stress (β= -0.36, p= .009) and lower level of depression (β = 0.30, p= .044) exerted a significant influence on decreased nHF in the multiple regression analysis. Conclusion: We suggest that men are more vulnerable to having reduced vagal activity on HRV than women. Since male gender, higher level of stress and lower level of depression level influenced decreased vagal activity, strategies are needed to improve stress and depression rather than anxiety especially for men, which contribute to promoting HRV to prevent cardiac health diseases.

The purpose of this study was to explore the degree of stress in caregivers caring for patients who had had a cerebro vascular accident as the stress is related to the self- care ability of the patient. The subjects for the study were caregivers of 111 CVA patients, hospitalized at two University affiliated hospitals and two general hospitals in Daejon. The survey instruments used in the study were Kang’s ADL Check List and a modified form of Lee’s Stress Inventory. The survey was conducted from July 16th to August 30th, 1992. The survey results were analyzed using the Statisitical Package for Social Sciences (SPSS) and can be sumerized as follows: 1. The level of self- care for the CVA patients was : 1) complete dependence (M=34.7, 31.2%), 2) complete independence (M=14.8. 13.3%), 3) in-complete independence ( M=17.5, 15.8% ), 4) in-complete dependence (M=14.8, 13.3%) and 5) dependence and independence (M=14.1, 12.7%). The items for which there was a high level of self-care were 1) drinking (M=3.640), 2) returning (M=2.351) and 3) eating (M=2.351) : and the items for which there was a low level of self -care were : 1) ascending and descending stairs (M=2.351), 2) dressing and undressing trousers (M=2.514) and 3) dressing and undressing jacket (M :2.532). 2. There was a statistically difference between the paralytic status and the level of self- care accord-ing to their demographic characteristics ( F=24. 7056, p(.001). 3. There was no significant difference in the degree of caregiver stress according to patient's demo-graphic characteristics. 4. There was a statistically significant difference in the degree of caregiver stress according to the following demographic characteristics : age (F=7.4189, p(.001), education level (F=5.8336, P(.01), family structure (t=2.10, p(.05) and their relationship with the patient (F=6.5099, P〈.01). 5. There was no significant difference in the degree of caregiver stress according to the level of patient self - care.

This study examines the relationship between mother's stress and cortisol level during late pregnancy and how it changes into postpartum periods. Thirty one families were recruited from Daejeon and Incheon in South Korea. The major findings were as follows: (1) The level of mothers' cortisol followed the typical diurnal pattern of decline throughout the day. Further longitudinal analysis revealed that the level of Korean mothers' cortisol steadily lowered from the 8th prenatal month to the 6th postnatal month. (2) During pregnancy, mothers reported to experience changes in physical activities, daily routines, eating habits, types or amount of social activities and sleeping habits. Among these they were stressed the most by changes in physical activities and social activities. (3) The results of postpartum depression tests conducted at two months after giving birth showed mothers at this time were mostly stressed from difficulty sleeping and unnecessary self criticism. (4) The level of psycho social stress in mothers at six months after giving birth was mainly on social roles and the questions about self reliance marked the highest points. (5) Overall, there was a tendency for the level of maternal stress to decrease definitely from before and after the delivery and even though the level of stress was steadily decreasing up to 6th postpartum month it was not as sharp as those of before and after the birth of the babies. The level of cortisol analysis also showed the same obvious tendency.

The present fast-moving era brings a serious stress issue that affects elders and youngsters. Everyone has undergone stress factors at least once in their lifetime. Stress is more among youngsters as they are new to the working environment. whereas the stress factors for elders affect the individual and overall performance in an organization. Electroencephalogram (EEG) based stress level classification is one of the widely used methodologies for stress detection. However, the signal processing methods evolved so far have limitations as most of the stress classification models compute the stress level in a predefined environment to detect individual stress factors. Specifically, machine learning based stress classification models requires additional algorithm for feature extraction which increases the computation cost. Also due to the limited feature learning characteristics of machine learning algorithms, the classification performance reduces and inaccurate sometimes. It is evident from numerous research works that deep learning models outperforms machine learning techniques. Thus, to classify all the emotions based on stress level in this research work a hybrid deep learning algorithm is presented. Compared to conventional deep learning models, hybrid models outperforms in feature handing. Better feature extraction and selection can be made through deep learning models. Adding machine learning classifiers in deep learning architecture will enhance the classification performances. Thus, a hybrid convolutional neural network model was presented which extracts the features using CNN and classifies them through machine learning support vector machine. Simulation analysis of benchmark datasets demonstrates the proposed model performances. Finally, existing methods are comparatively analyzed to demonstrate the better performance of the proposed model as a result of the proposed hybrid combination.

Purpose : Investigate the effects of Haeganjeon water extract (HGJ) on immobilization-stress or cold-stress in C57BL/6J mice. Methods : Male C57BL/6J 30 mice of weighting 18${\pm}$2g, were divided into sixs groups including the immobilization-stress group(5heads), after immobilization-stress HGJ oral administration(500mg/kg) groups(5heads), cold-stress group(5heads) and after cold-stress HGJ oral administration(500mg/kg) groups(5heads). then we observed changes in the serum histamine and corticosterone level and changes immune system. Results : HGJ decreased the serum level of histamine and corticosterone increased by immobilization-stress or cold-stress. HGJ inhibited the release of histamine from mast cells. In addition, HGJ enhanced the cell viability of thymocytes decreased by immobilization-stress or cold-stress and decreased DNA fragmentation of thymocytes increased by immobilization- stress or cold-stress. Also, HGJ increased the cell viability of splenocytes decreased by cold-stress and decreased DNA fragmentation of splenocytes increased by cold-stress. HGJ decreased the population of thymic CD4+ cells increased by immobolization-stress. HGJ increased the population of B220+ cells decreased by immobilization-stress and decreased the population of Thy1+ cells increased by immobilization-stress. Also, HGJ decreased the population of splenic CD4+ cells increased by immobolization-stress. HGJ enhanced the production of ${\gamma}-interferon$ decreased by immobilization-stress or cold-stress and increased the production of interleukin-4 decreased by immobilization-stress. Furthermore, HGJ enhanced the phagocytic activity decreased by immobilization-stress or cold-stress and enhanced the level of nitric oxide decreased by immobilization-stress or cold-stress. Conclusion : HGJ may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of immune response.
