Objectives : The purpose of this study was to investigate the correlation of stress and meridian muscle electrography in Korean adult males. Methods : Sixty-nine volunteers suffering from stress participated in this study. Physical examination, stress survey and meridian muscle electrography were performed. Each variable was compared with each other by correlation analysis. Results : Correlation between stress response inventory and fatigue of trapezius muscle right upper portion was statistically significant. In relationship between sub scales of stress response inventory and meridian muscle electrography, fatigue of trapezius muscle right upper portion was statistically significant with tension, depression, and frustration. Contraction power of left sternocleidomastoid muscle was significant with somatization and others were not significant. Conclusions : In Korean adult males, trapezius muscle shows more fatigue under more stress. This suggests that stress influences muscle fatigue. Although meridian muscle electrography is not a typical method for the evaluation of pain nor stress, this is referential method to clinical evaluation of painful shoulder caused stress.

Most people suffer from stress during day life because modernized society is very complex and changes fast. Because stress can affect to many kind of physiological phenomena it is even considered as a disease. Therefore, it should be detected earlier, then must be released. When a person is being stressed several bio-signals such as heart rate, etc. are changed. So, those can be detected using medical electronics techniques. In this paper, stress assessment system is studied using random forest algorithm based on heart rate, RR interval and Galvanic skin response. The random forest model was trained and tested using the data set obtained from the bio-signals. It is found that the stress assessment procedure developed in this paper is very useful.

This study explored the relationship between parental reaction to children's negative emotions, child's self-regulation and stress-coping behaviors. This study also examined the mediating effect of a child's self-regulation between parental reactions to children's negative emotions and a child's stress-coping behaviors. The sample included 407 elementary school 5th-6th grades and their parents (comprising 407 couples) in Seoul. The research results are summarized as follows. First, parental reactions to children's negative emotions were significantly related to the child's self-regulation and stress-coping behaviors. Secondly, it was also found that parental reactions to children's negative emotion were both partially and indirectly related to a child's stress-coping behaviors through the child's use of self-regulation.

An attempt has been made to measure existing steel stress using magnetoelasticity. A device has been developed and used for the measurement of magnetism in response to the deformation of a steel bar. The proposed technique can be used for the assessment of existing reinforced concrete structures by the measurements of steel stress embedded inside concrete. A traditional technique requires to break the existing steel bar to measure existing strain. However, the proposed technique is developed to measure the stress without damaging the steel bar. A successful application of magnetoelasticity depends on the establishment of relationship between elastic and magnetic response due to loading. To investigate the correlation between the two, steel bars are loaded in tension under uniaxial loading while the magnetic reading is recorded. Based on the test results, equations are suggested to predict stress for steel bars with different diameters.

Objectives : We investigated the characteristics of perceived stress response and relationship between some variables of gastrointestinal symptoms(esp., dyspepsia) and subscales of perceived stress response inventory(PSRI) in patients with upper gastointestinal disorder when they perceived stress. Methods : 84 patients with upper gastrointestinal disorder(gastritis, gastric ulcer, duodenal ulcer etc.) and 94 normal controls completed the PSRI developed by Korean psychiatrists. The patient group performed the questionnaire including some variables of gastrointestinal symptoms. Results : Internal consistency was statistically significant in all subscales of PSRI. The patient group was significantly higher at total score of PSRI, general somatic symptom subscale score, specific somatic symptom score than control group. As the result of stepwise regression analysis for relationship between some variables of gastrointestinal symptoms ans subscales of PSRI, specific somatic symptom subsclae closely related with illness duration, past illness history and severity of symptom, and the lowered cognitive function & general negative thinking subscale related with the existence of emotional distress. Conclusion : Patients with upper gastrointestinal disorder showed stronger perceived stress response than control group and they experiences somatic symptoms related to autonomic nervous system and/or gastrointestinal symtoms rather than emotional, cognitive, behavioral symtoms when they perceived stress. They also responded to stress as they expeirenced specific somatic symtom when they had long illness duration, past illness history, and high severity of symptom and the existence of emotional distress could develop lowered congnitive function and general negative thinking.

The purpose of this study was to investigate the stress response of nurses working on psychiatric wards (psychiatric nurses) compared with that of nurses working on general wards (general nurses) in order to provide assessment data for intervention of the stress response. The Symptoms of Stress Inventory was used to measure the stress response. Data were collected by a direct survey method using a questionnaire and were collected from March first to March 30, 1995. A sample of 200 nurses working in three psychiatric hospitals and psychiatric wards in four university hospitals in Seoul and Kangwon province were selected and 200 nurses working on general wards from two general hospitals in Seoul were also selected for a total sample of 400 nurses. Nurses who had experienced more than one of the major life events in the last two years were excluded from the total number in the samples, so the final sample was 161 psychiatric nurses, and 169 general nurses. The Scores for the total stress response, scores of the SOS subscales, stress response by sociodemographic characteristics of the nurses working on the psychiatric wards were compared with those of nurses working on the general ward. The results of this investigation are as follows 1. The mean total SOS score for the psychiatric nurse was 0.81 (SD=0.48) and that of the general nurses was 0.90(SD=0.53). 2. The Mean score for peripheral manifestation, con tral-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, de-pression, anxiety, anger and cognitive disorganization for the general nurses showed a tendency to be higher than those of the psychiatric nurses. Mean score for cardiopulmonary symptoms for the general nurses was significantly higher than that of the psychiatric nurses. 3. The mean scores for the sixteen SOS items for the general nurses was significantly higher than for the psychiatric nurses. The 16 items were flushing of the face, sweating excessively even in cold weather, thumping of the heart, rapid breathing, dry mouth, a choking lump in the throat, hoarseness, muscle tension in hands or arm, muscle tension in leg, working tiring one out completely, severe aches a핀 Pain make it diffi-cult to do the work, severe nervous exhaustion, worrying about health, feeling weak and faint, so upset that one wants to hit something, unable to keep thoughts from running through one's mind. The mean score of only 505 item were significantly higher for the psychiatric nurses. 4. Stress responses between psychiatric nurses and general nurses were significantly different according to the following demographic characteristics : marriage, duration of work, position, accommodation, planning to move into another working site, working ward, education in psychiatric nursing.

Objectives The purpose of the present study was to examine the relationship between the chronotype and the burnout, so we investigated the mediating effects of the mediators such as perceived stress, stress response, and depression. Methods Employees working at Incheon Customs conducted a mental health self-examination through the internet. Among them, 174 people who agreed to the mental health survey participated in the study. Participants completed questionnaires including Composite Scale of Morningness (CSM), Center for Epidemiological Studies-Depression Scale (CES-D), Perceived Stress Scale (PSS), Stress Response Inventory (SRI), Maslach Burnout Inventory-General Survey (MBI-GS). Results Our results showed a higher degree of CES-D, SRI, exhaustion, and cynicism in evening and intermediate type compared to morning type, and a higher degree of professional efficacy in morning type compared to intermediate type. CSM was shown to have a direct effect on exhaustion and indirect effect through CES-D and SRI. CSM also had a direct effect on professional efficacy and had an indirect effect through the CES-D. However, CSM was found to have only indirect effects through the SRI for Cynicism. Conclusions In this study, individuals with evening type tend to experience a high degree of burnout (exhaustion, cynicism and professional efficacy) through the mediation effect of depression and stress response. Further study is necessary to reveal the effect of management of the depression and stress response in the employee with evening type.

The yeast Saccharomyces cerevisiae has defense mechanisms identical to higher eukaryotes. It offers the potential for genome-wide experimental approaches owing to its smaller genome size and the availability of the complete sequence. It therefore represents an ideal eukaryotic model for studying cellular redox control and oxidative stress responses. S. cerevisiae Yap1 is a well-known transcription factor that is required for $H_2O_2$-dependent stress responses. Yap1 is involved in various signaling pathways in an oxidative stress response. The Gpx3 (Orp1/PHGpx3) protein is one of the factors related to these signaling pathways. It plays the role of a transducer that transfers the hydroperoxide signal to Yap1. In this study, using extensive proteomic and bioinformatics analyses, the function of the Gpx3 protein in an adaptive response against oxidative stress was investigated in wild-type, gpx3-deletion mutant, and gpx3-deletion mutant overexpressing Gpx3 protein strains. We identified 30 proteins that are related to the Gpx3-dependent oxidative stress responses and 17 proteins that are changed in a Gpx3-dependent manner regardless of oxidative stress. As expected, $H_2O_2$-responsive Gpx3-dependent proteins include a number of antioxidants related with cell rescue and defense. In addition, they contain a variety of proteins related to energy and carbohydrate metabolism, transcription, and protein fate. Based upon the experimental results, it is suggested that Gpx3-dependent stress adaptive response includes the regulation of genes related to the capacity to detoxify oxidants and repair oxidative stress-induced damages affected by Yap1 as well as metabolism and protein fate independent from Yap1.

The primary purpose of this study was to assess the relation of stress perception and poststroke. This study was done on 50 stroke patients in hospital. According to activities of functional impairment, they were classified into walking disturbance, motor weakness, dysphagia, or reattack etc. The stress perception test(GARS Scles) and stress response assessment shows the follwing results. 1. On the distribution in the stroke 50 patients, For the majority group were male in sex, sixty inage, middle towns people in residence. 2. On the comprehensive GARS scale scores, It marked the higest scores thirty at age, merchandise or salesman on jobs, a city in residence. There was no signigicant difference in mean GARS Scales scores between males and females group, the left hemiplegia and the Rt hemiplegia. 3. On the comprehensive GARS Scale tests, Overall glogal stressor(G8) and sickness stresor(G4) marked the highest scores of all GARS Scales. 4. On the comparative assessment of each group's stress reponse test scores, zung-bu(中腑) was showed higher scores than the other group in oriental diagnosis and hemorrage was showed higher scores than the other group in western medical diagnosis. 5. On the comprehensive assessment of each group's stress reponse test scores, aphsia(不語) marked the highest scores in another disphagia group's. It marked the highest scores in another group's that banshinbulsoo(半身不遂) as regards as hemiplegia generally. Standing disability is the higher scores than another group's walking alone or assist, and standing alone. 6. Secondary attack is the highest scores of all reattack stroke on the stress repones test. 7. Comparing and analyzing the GARS Scale total scores and GARS Scale subject fator at stroke, we found that sickness stressor and fininial stressor is showed the highest correlated to stress response fowlloing stroke. With those results, we can see that functional impairment following stroke is correlated to stress perception and reponse. In the furture studies using, we hope that the findings the study would have clinical relevance to the psychosocial adjustment and total rehabilation of stroke patients.
