Purpose: The purpose of this study was to investigate the effects of general, health, and alcohol-related characteristics on blood pressure and stress according to the Alcohol Use Disorders Identification Test (AUDIT). Methods: This was a descriptive study. From participants in the 2013 Korea National Health and Nutrition Examination Survey, 319 participants who responded to the survey when they were attending college or university were selected. Data were analyzed using the SPSS Win 23.0 program for composite sample data reflecting the composite design elements of stratification, colonization, and weighting. Results: Mean age of onset of alcohol drinking was $17.91{\pm}0.16$ years, the average AUDIT score was $7.56{\pm}0.41$, and 25 (9.1%) participants fell into the high-risk drinking group. In the high-risk AUDIT group, systolic blood pressure was influenced by age, gender, institution, health status, body mass index, and suicidal ideation, and the explanatory power of the model ($R^2$) was 75.0%. For diastolic blood pressure, institution and health status were the influential factors, and $R^2$ was 66.2%. Predictors of stress were health status, depression, and the age of onset of drinking, and $R^2$ was 57.2%. Conclusion: It was confirmed that the explanatory power of the variables in models of systolic and diastolic blood pressure and stress is greater in those with higher scores on AUDIT.

Background: A chronic social defeat stress (CSDS) model has been proposed as relevant to stress-induced behavioral change in humans. In this study, we examined the effect of Korean Red Ginseng (KRG) on CSDS-induced mood disorders and protein expression in an animal model. Methods: To evaluate the effect of KRG on social defeat stress, test mice were exposed in the resident aggressor's home cage compartment for 14 days beginning 1 h after KRG treatment (10, 20, and 40 mg/kg, per oral (p.o.)). After the exposure, behavioral tests to measure anxiety, social interaction, and depression-like behavior were performed. To investigate the underlying mechanism, N-methyl-D-aspartate receptor expression levels in CSDS-induced mice were evaluated using Western blot analysis. Results: CSDS induced anxiety-like behaviors by decreasing central activity in the open-field test and open-arm approach in the elevated plus maze test and led to social avoidance behavior in the social interaction test. CSDS mice showed upregulated NR1, NR2A, and NR2B expression in the hippocampus. KRG 20 and 40 mg/kg ameliorated anxiety-like activities and KRG 20 mg/kg alleviated social avoidance by decreasing time in the corner zone. KRG treatment recovered CSDS-induced NR1, NR2A, and NR2B protein levels in the hippocampus. Conclusion: These results indicate that KRG has a therapeutic effect on CSDS-induced mood disorder by alleviating N-methyl-D-aspartate receptor overexpression in the hippocampus.

목적 : 자폐 스펙트럼 장애(Autistic Spectrum Disorders, 이하 ASD)는 비전형적 감각 적응, 의사소통 문제, 상동 행동 등이 특징인 발달 장애로 섭식장애가 흔하게 동반된다. ASD 아동의 섭식장애는 감각, 구강운동, 행동, 인지, 사회성 등 다양한 원인으로 발생하며 주요 증상으로는 까다로운 먹기, 선택적 먹기, 음식 거부, 새로운 음식 거부, 음식 다양성 제한, 음식 혐오 등 다양하다. 또한 건강 및 영양 섭취 문제, 섭식 발달, 섭식 관련 사회성, 가족과 보호자의 스트레스 등 다양한 문제가 동반되기도 한다. ASD 아동의 섭식장애는 출생 후부터 나타날 수 있으며 일반적으로 진단이 이루어지는 3세 이전에 발생하기 때문에 적절한 중재 제공 전 공백이 발생할 수 있다. 보통 섭식장애 증상은 연령이 증가할수록 감소되는 경향이 있으나 증상 자체는 남아 있는 경우가 많아서 조기 평가 및 중재, 지속적인 확인이 필요하다. 본 연구에서는 ASD 아동의 섭식장애 특성과 영향을 주는 요인, 중재법에 대한 일반적인 내용을 문헌 고찰을 통해 확인하였다. 결론 : ASD 아동의 섭식장애 중재로는 감각 기반 중재와 행동 기반 중재가 일반적이다. 감각 기반 중재는 음식 민감성, 행동 기반 중재는 음식 선택성에 효과적인 방법이다. 또한 ASD 아동의 섭식장애 증상이 다양한 만큼 감각 및 행동 기반 중재를 기본으로 놀이와 참여, 구강운동, 식이와 일상생활까지 포함된 종합적인 접근이 필요하다. 그러나 아직 ASD 아동의 섭식장애 중재를 위한 적절한 평가와 중재 프로토콜 및 가이드라인이 부족한 상황으로 보다 체계적인 이해를 바탕으로 한 복합적인 접근이 필요하다. 작업치료사 등 연하재활 전문가는 종합적인 이해를 바탕으로 ASD 아동의 섭식장애 해결을 위한 적절한 평가 및 중재를 제공해야 할 것이다.

The etiology of most psychiatric disorders is still incompletely understood. However, growing evidence suggests that stress is a potent environmental risk factor for depression and anxiety. In rodents, various stress paradigms have been developed, but psychosocial stress paradigms have received more attention than non-social stress paradigms because psychosocial stress is more prevalent in humans. Interestingly, some recent studies suggest that chronic psychosocial stress and social isolation affects mainly anxiety-related behaviors in mice. However, it is unclear whether chronic non-social stress induces both depression- and anxiety-related phenotypes or induces one specific phenotype in mice. In the present study, we examined the behavioral consequences of three chronic non-social stress paradigms: chronic predictable (restraint) stress (CPS), chronic unpredictable stress (CUS), and repeated corticosterone-HBC complex injection (RCI). Each of the three paradigms induced mild to severe depression/despair-like behaviors in mice and resulted in increased immobility in a tail suspension test. However, anxiety-related phenotypes, thigmotaxis and explorative behaviors, were not changed by the three paradigms. These results suggest that depression- and anxiety-related phenotypes can be dissociated in mouse stress models and that social and non-social stressors might affect brain circuits and behaviors differently.

Ergonomic intervention techniques were adopted to assess and control potential risk factors of work-related musculoskeletal disorders(WMSDs) in the automated light assembly manufacturing system. Ten different kinds of assembly workstations implemented with a conveyor system and twelve female workers were observed and evaluated with careful video film analysis. Several close examinations using sets of checklists established by qualified safety and health organizations, such as NIOSH, OSHA, and ANSI, were conducted and every workers and staffs in the site participated in the self-report questionnaires and off-line interviews. Typical risk factors and symptoms of the upper extremity musculoskeletal disorders were found and categorized into specific parts of body. To reduce risk factors of WMSDs and improve system productivity new revised workstation standards, physical dimensions, were suggested accordant with anthropometric characteristics of workers and a heuristic decision strategy of rotating shift work schedules according to work contents has proposed to mitigate cumulative physical stress. Finally, ergonomic programs of entire company to prevent WMSDs were structured.

Purpose: This study was done to identify relationships among post-traumatic stress (PTS), job stress and turnover intention in emergency department (ED) nurses. Methods: Participants were 250 ED nurses who had worked for one month or longer in the ED one of three university hospitals or seven general hospitals in Daegu City or Gyeong Buk Province in Korea. Structured questionnaires were used to measure PTS, job stress, and turnover intention of participants. Data were analyzed using descriptive statistics, one-way ANOVA, path analysis, and stepwise multiple regression with the SPSS program. Results: There were significant relationships between PTS, job stress and turnover intention. PTS influenced turnover intention directly and was indirectly mediated by job stress. The experience of traumatic events influenced PTS, job stress, and turnover intention. Indirect experience of traumatic events in the ED was an important predictor, explaining 20.1% of PTS in high-risk post-traumatic participants. Conclusion: PTS can be an important factor for job stress and turnover intention. The direct and indirect experience of traumatic events can influence PTS, job stress, and turnover intention in ED nurses. Based on these results, strategies for managing PTS and relating job stress are recommended to reduce turnover intention in ED nurses.

As an aging population is increasing, more elderly people are exposed to traumatic stress. Although this issue has received more attention in some literature, it is clear that numerous questions exist in aftermath of trauma exposure in elderly people. In case of Korean elderly suffers, traumatic experience includes the Korean war, military dictatorship and violent demonstration. Studies regarding elderly PTSD is not active and a lot of patients are not still engaged in treatment. We suggest that concerns that are unique to this population are necessary.

A substantial body of evidence indicates that reactive oxygen intermediates (ROIs) are implicated in pathogenesis of diverse human diseases, including cancer, diabetes and neurodegenerative disorders. Oxidative stress induced by ROIs often causes cell death via apoptosis that is regulated by a plenty of functional genes and their protein products. In the present work, we have investigated the role of bcl-2 in protecting against oxidative death induced by hydrogen peroxide in cultured rat pheochromocytoma (PC12) cells. (omitted)
