The Work-Related Musculoskeletal Disorders(WMSDs) have been an rising issue since the 1970s. So many manufacturing companies have been tried to improve the work environments for the control and the prevention of the WMSDs. Specific risk factors associated with WMSDs include repetitive motion, heavy lifting, forceful exertion, contact stress, vibration, awkward posture and rapid hand and wrist movement. But recently it has reported that besides working conditions, job stress is the important hazard causes which lead to WMSDs. This study investigates the relation between WMSDs and Job stress from 1426 workers in Heavy Industry. Job stress was evaluated by Karasek's model. Job stress was associated with job satisfaction. Job demand was associated with the WMSDs, but job control was not associated with the WMSDs. The results can be used to design the management program for the WMSDs and the job stress.

Purpose: This study suggests clinical reasoning strategies for therapists with little experience in clinical reasoning for the evaluation and treatment of patients with neurological disorders. Methods: The suggested method was the mnemonic PT STRESS whose initials represent the body structure and functions that can affect the activity limits and the items that can cause problems at the functional level in patients with neurological disorders. Results: PT STRESS stands for pain (P), ability of the trunk (T), sensation (S), tone (T), range of motion (R), emotion and endurance (E), muscular strength (strength), and stability (S). It tests and measures problems in the body structure and functions. Conclusion: This study suggests easy clinical reasoning strategies that can be used by therapists who have insufficient experience in the evaluation or treatment of patients with neurological disorders. However, more factors need to be considered in the future with regard to clinical reasoning of the diverse problems of patients with neurological disorders.

Cognitive-behavioral approach can be clinically applied to coping with stress, because cognitions are playing a central mediating role in the occurances of stress and stress reactions. In other words, cognitive distortions can be associated with causing and/or maintaining psychopathology. The goal of cognitive-behavioral approach is to help the patients identify and alter cognitive distortions and maladaptive assumptions. This approach is aimed not at curing but rather at helping the patients to develop better coping strategies to deal with their life and work. The cognitive-behavioral techniques often used in this approach include problem solving, hypothesis-testing, self-monitoring, cognitive challenges, generating alternatives to automatic cognitive distortions, self-instruction, attribution and reattribution, and techniques to control or suppress thoughts. This approach is considered to be helpful for treatment and prevention of psychiatric disorders including psychosomatic disorders, in which stress can greatly affect their onset and course.

Purpose: The purposes of this study were to investigate hospital nurses' job stress, sleep disturbance, and fatigue and to examine the relationships among them. Methods: The subjects were 119 registered nurses working in two hospitals. The data were collected from September 1 to September 30, 2015 using self-report questionnaires. The data were analyzed using SPSS 20.0 program. Results: Job stress levels of nurses were middle or higher level. Nurses levels of sleep disorders was higher than the median. It was the middle of the fatigue level of the nurses. There was a difference between sleep disorders and fatigue, depending on age and working department. There was a significant quantitative correlation among stress, sleep disorders, and fatigue. Conclusion: Therefore, it is necessary to develop programs to reduce job stress and sleep disorders and fatigue of hospital nurses. And it requires institutional improvements.

Our daily lives have changed a lot because of the COVID-19 pandemic. This is essential to reduce the spread of COVID-19 due to public health measures such as social distancing. At the same time, however, they are exposed to depression, anxiety disorders, depressive disorders, trauma and stress-related disorders. For this, we developed an application that can check HRV data and stress index by measuring ECG and PPG based on a Smart Watch device that can measure bio-signals in real time. In the case of the developed application, the heart rate is measured and displayed in real time to deliver basic exercise information by measuring exercise, steps and calories, and total distance, and smoothly based on blood pressure, heart rate, and HRV data as a measurement program. Through this, I believe that the IoT Smart Stress Care Application, which can manage mental health by itself, will be helpful to patients with stress and depressive trauma disorders.

Purpose: This study aimed to investigate the effect of stress and oral parafunctional habits on temporomandibular joint disorders (TMD) in college students. Methods: An online survey comprising 354 questionnaires was conducted from May 23, 2020, to June 21, 2020. The collected data were analyzed using Student's t-test, one-way analysis of variance, correlation tests, and multiple regression analysis. Results: The stress symptom score was higher in females than in males. The symptoms of physical stress were significantly higher among students from the Department of Public Health, whereas those of psychological stress were higher among students from the Department of Physical Education. Both TMDs and oral parafunctional habits were higher among females, students of the Departments of Arts and Physical Education, and seniors. The higher the stress symptom level, the higher the scores for TMD and oral parafunctional habits. TMD and oral parafunctional habits were found to be most affected by physical stress. Conclusion: These findings indicate that a reduction in physical stress is required to decrease the prevalence of oral parafunctional habits and TMDs among college students. This can be achieved by the incorporation of physical activity programs, which may aid in reducing the symptoms of physical stress.

The psychosocial stress and musculoskeletal disorders(MSDs) have been one of major health problems for hospital workers. This study tried to understand the relationship between symptoms associated with MSDs and risk factors such as working posture, job stress, psychosocial stress and fatigue. A total number of 655 hospital workers participated in this study. Specifically, REBA was applied for evaluating working posture and a checklist prepared by KOSHA(Korean Occupational Safety and Health Agency) was used for symptom survey. A questionnaire from KOSHA was also used for collecting data associated with job stress, psychosocial stress and fatigue. All these data were formulated and modeled by path analysis which was one of major statistical tools in this study. Specifically, path analysis for the data we collected came up with several major findings. The risk scores from working posture based on REBA had indirect effects via fatigue factor(MFS) as well as direct effects on symptoms. The factors associated with job stress(KOSS) and psychosocial stress(PWI-SF) had significant effects on symptoms. Specifically, indirect effect of job stress factors via fatigue factors(MFS) had bigger than that of direct effect of job stress on symptom.

Objective Posttraumatic stress disorder (PTSD) is distinct from anxiety disorders in its etiology and clinical symptomatology, and was reclassified into trauma- and stressor-related disorders in DSM-5. This study aimed to find neurophysiological correlates differentiating PTSD from anxiety disorders using resting-state quantitative electroencephalography (qEEG). Methods Thirty-six patients with either PTSD or acute stress disorder and 79 patients with anxiety disorder were included in the analysis. qEEG data of absolute and relative powers and patients' medication status on the day of qEEG examination were obtained. Electrodes were grouped into frontal, central, and posterior regions to analyze for regional differences. General linear models were utilized to test for group differences in absolute and relative powers while controlling for medications. Results PTSD patients differed from those with anxiety disorders in overall absolute powers [F(5,327)=2.601, p=0.025]. Specifically, overall absolute delta powers [F(1,331)=4.363, p=0.037], and overall relative gamma powers [F(1,331)=3.965, p=0.047] were increased in PTSD group compared to anxiety disorder group. Post hoc analysis regarding brain regions showed that the increase in absolute delta powers were localized to the posterior region [F(1,107)=4.001, p=0.048]. Additionally, frontal absolute gamma powers [F(1,107)=4.138, p=0.044] were increased in PTSD group compared to anxiety disorder group. Conclusion Our study suggests increased overall absolute delta powers and relative gamma powers as potential markers that could differentiate PTSD from anxiety disorders. Moreover, increased frontal absolute gamma and posterior delta powers might pose as novel markers of PTSD, which may reflect its distinct symptomatology.
