Purpose: The purpose of this study was to investigate the factors contributing to temporomandibular joint disorder symptoms. Methods: The survey was conducted from May 1 to June 10 2017 against college students(120 males and 123 females) in Daejeon and Gangwon who understood the purpose of this study and agreed to participate. Results: First, The most frequent symptom of temporomandibular joint disorders is noises from the joint (male 45%, female 61.8%), followed by headache or neck pain (male 25.8%, female 52.8%). There was shown a significant difference by gender in all items except for jaw dropping, poor alignment of teeth and trauma(p<0.05).

Work related musculoskeletal disorders (WMSDs) have become a hot issue within the Korean workplace for the past several years. Recently, the effect of job related stress on WMSDs, cerebro-cardiovascular diseases, and psychiatric disorders has been steadily increasing. The study conducted questionnaire of Korea version job stress model, WMSDs from NIOSH, CES-D (Center for Epidemiologic Studies Depression Scale), and STAI (State-Trait Anxiety Inventory) against train drivers. The results of this study show that the job stress score of the train drivers is high in the areas of physical environment, job latitude, interpersonal conflict, job insecurity, and organization system. The relation between job stress and WMSDs nd, interpersonal conflict, job insecurity and organizational system. The relation between job stress and depressive disorders showed statistical significance in the areas of job demand, job insecurity and low reward. Finally, the relation between job stress and anxiety disorders showed statistical significance in areas of job demand, interpersonal conflict, job insecurity, organizational system and low reward.

Tea polyphenols especially catechins have long been studied for their antioxidant and radical scavenging properties. Scientists throughout the world have investigated the usefulness of the regular green tea consumption in several disease conditions. In-vitro and in-vivo experiments on catechins especially epigallocatechingallate have revealed a significant role in many ways. Reactive oxygen species have been increasingly implicated in the pathogenesis of many diseases and important biological processes. Toxic effects of these oxidants, commonly referred to as oxidative stress, can cause cellular damage by oxidizing nucleic acids, proteins, and membrane lipids. Oxidative stress has been related to aging and age related disorders. It is found that in a wide variety of pathological processes, including cancer, atherosclerosis, neurological degeneration, Alzheimer's disease, ageing and autoimmune disorders, oxidative stress has its implications. Catechins have been reported to be useful in combating aging and age related disorders like cancer, cardiovascular disorders and neurodegenerative diseases. In this mini review we will discuss such studies done across the globe.

This study analyzed the effect of workers' socio-psychological burden factors on musculoskeletal disorders. A survey was conducted targeting office and field workers in the Seoul metropolitan area. Analysis was performed using the results of 357 surveys out of 400 surveys. The analysis results were derived as follows. First, the socio-psychological burden factor did not show statistically significant results for musculoskeletal disorders. Second, it was found that job stress factors also had a positive effect on musculoskeletal disorders. Third, social psychological burden factors were found to be more positive than office workers than field workers. Fourth, there was a statistically significant correlation between job stress and musculoskeletal disease risk scores. From the above results, job stress factors affect musculoskeletal disease risk factors (work frequency, pain level, and duration) and the increase in musculoskeletal disorders and the number of accidents.

치과위생사의 주요 건강문제인 근골격계 장애를 조사하고, 근무환경 요인과 스트레스 및 근골격계 장애의 관련성을 파악하기 위해 광주지역 치과위생사 483명을 편의 추출하여 자기기입식 설문조사를 시행하고 빈도분석, 교차분석, t-검정, 다중 로지스틱 회귀분석을 실시하여 분석한 결과는 다음과 같다. 연구대상자의 심한 통증을 호소하는 정도인 근골격계 장애는 29.8%였다. 근무환경요인과 스트레스 및 근골격계 장애의 관련성을 파악한 결과, 근무환경 요인에서 휴식시간 빈도였으며, 그 외 스트레스 요인 등이었다. 근무환경 요인에서 휴식시간 빈도가 없음으로 응답한 군에 비해 2회라고 응답한 군의 OR은 0.29 (95% CI, 0.11~0.73)로 근골격계 장애가 감소하여 유의한 차이를 보였으나, 휴식시간 빈도가 1회와 3회 이상에서는 유의한 차이가 없었다. 스트레스의 근골격계 장애 OR은 0.44 (95% CI, 0.27~0.70)로 음의 상관관계를 보였다. 이것은 휴식시간 빈도가 적당할수록(2회일 때) 근골격계 장애가 낮음을 의미하며, 근골격계 장애가 있는 경우 스트레스가 낮게 나타났다.

The Unfolded Protein Response (UPR) serves as a critical cellular mechanism dedicated to maintaining protein homeostasis, primarily within the endoplasmic reticulum (ER). This pathway diligently responds to a variety of intracellular indicators of ER stress with the objective of reinstating balance by diminishing the accumulation of unfolded proteins, amplifying the ER's folding capacity, and eliminating slow-folding proteins. Prolonged ER stress and UPR irregularities have been linked to a range of neuropsychiatric disorders, including major depressive disorder, bipolar disorder, and schizophrenia. This review offers a comprehensive overview of the UPR pathway, delineating its activation mechanisms and its role in the pathophysiology of neuropsychiatric disorders. It highlights the intricate interplay within the UPR and its profound influence on brain function, synaptic perturbations, and neural developmental processes. Additionally, it explores evolving therapeutic strategies targeting the UPR within the context of these disorders, underscoring the necessity for precision and further research to effective treatments. The research findings presented in this work underscore the promising potential of UPR-focused therapeutic approaches to address the complex landscape of neuropsychiatric disorders, giving rise to optimism for improving outcomes for individuals facing these complex conditions.
