Objectives : The purpose of this study was to investigate the relationship between masseter and cervical muscle activity and temporomandibular disorder in female office workers. Methods : Experimental group of 24 healthy subjects complained of temporomandibular joint related to computer use which lasted more than 3 months in the past year and was present in the past 7 days as well as on the day of test. Control group of 20 healthy subjects had no complaints of minimal discomfort on the day of test, and had no discomfort in the past 7 days. If they had reported discomfort in the past 12 months, it was of a short duration(<3 months) and resolved at least 3 months prior to participation. Outcomes were assessed by meridian-electromyography(MEMG), whole spin x-ray, mandibular function impairment questionnaire(MFIQ), neck disability index(NDI), visual analog scale(VAS), Beck depression inventory(BDI), stress reaction inventory(SRI) and Holmes & Rahe social readjustment rating scale(SRRS). Results : The contraction power of masseter muscle, upper trapezius, sternocleido-mastoid muscle and erector spinae by MEMG was significantly higher in the experimental group. The muscle fatigue of masseter muscle and sternodeido-mastoid muscle by MEMG was significantly higher in the experimental group. SRI was significantly higher in experimental group. There was no significant difference between two groups in the Jackson's angle, Cobb's method and cranio-cervical posture. Conclusions : The results suggest that temporomandibular disorder related mental stress but physical stress does not change cervical structure significantly.

Psychological stress and physical fatigue, such as anxiety, fear, sleep disturbance, etc., caused by exposure to the war, can lead to post-traumatic stress syndrome(PTSD) or war syndrome. The military has also prepared for drug use to minimize war syndrome and preserve combat strength. However, efforts to prevent war syndrome are still lacking. This study was conducted to identify biomarkers that can track psychophysiological changes. Psychophysiological changes associated with PTSD can be divided into four main categories. The four categories are behavioral changes, changes in brain cognition, neuroimmunological changes, and changes in innate immunity. This study suggest that biomarker profile can be made by the distance moved and the anxiety-like behavior in the open field for behavior category, brain BDNF levels in the brain cognition category, serum corticosterone in the neuroimmunology category, and inflammatory cytokine levels in the innate immunity category.

Purpose: Uncertainty and restrictions on daily life have increased fear, stress, and depression during the coronavirus disease 2019 (COVID-19) pandemic. Depression is the most common mental health problem in pregnant women. The purpose of this study was to evaluate the levels of fear and stress related to COVID-19 experienced by pregnant women, as well as their levels of depression, and to examine the factors associated with depression during pregnancy. Methods: This was a cross-sectional, correlational study conducted among 153 pregnant women who visited a maternity hospital in Busan, South Korea. A self-reported questionnaire was used for data collection from December 18, 2021 to March 8, 2022. Data were analyzed using descriptive statistics, the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression. Results: Pregnant women experienced a moderate level of fear related to COVID-19, with an average score of 21.55±4.90. The average score for depression during pregnancy was 14.86±11.10, with 50.3% of the participants experiencing depression (≥13). The factors associated with depression during pregnancy were fear of COVID-19, contact with a confirmed case of COVID-19, being in the third trimester of pregnancy, high stress levels due to difficulties experienced from social distancing measures, and unintended pregnancy. These five statistically significant factors explained 35.0% of variance in depression during pregnancy. Conclusion: Considering the prevalence of depression in pregnant women during the COVID-19 pandemic, it is necessary to develop interventions to reduce anxiety by providing correct information and alleviating the stress of social distancing.

Objectives : To investigate the correlations among alcohol consumption, alcoholic liver disorders, physical symptoms, and behaviors in heavy drinkers. Methods : 53 males who self-realized their severe alcohol consumption were enrolled in this study. 10 answers for a questionnaire, serum parameter, sonographic finding and body mass index were attained. The correlations between them were analyzed using Pearson's correlation and Student's t-test. Results : The average consumption of alcohol in these subjects was 2.5-fold over social drinkers. The incidence of alcoholic hepatitis was around 30%, while fatty liver 73%, and abnormal GGT 77%, respectively. No specific correlation between average volume of daily alcoholic consumption and alcohol-related hepatic parameters was shown in this study, but correlative tendency between fatty liver and body mass index was exhibited. Conclusions : This study may indicate that alcoholic liver injuries are caused by not just volume of alcohol consumed but more mixed factors including inherited genetic components, body fat mass, foods and other physical or emotional stress.

본 연구에서는 W (Tungsten)를 주 구성 물질로 불순물 C (Carbon)과 N (Nitrogen)을 첨가한 W-C-N 확산방지막 시편을 제조하였고, $N_2$가스의 유량을 변화시키면서 확산방지막을 제조하여 각각의 시료에 대하여 $600^{\circ}C$열처리를 하였다. 실험 결과 질소유량의 변화에 따라 시편의 탄소성 구간층의 물성 변화율이 시편의 탄성구간보다 큰 것을 알아냈다. 이는 질소 가스의 유량 변화가 시편의 탄소성 구간에 더욱 직접적으로 연관이 되었다는 것을 알 수 있었다. 각 시료는 16회 연속 압입 실험을 실시하여 Stress-strain curve를 통하여 질소 가스의 유량이 2 sccm인 박막의 분산이 적음을 알아냈고, 연속압입을 통하여 얻어진 상항복점의 표준 편차 역시 질소 가스의 유량이 2 sccm인 박막이 가장 적다는 것을 알 수 있었다. Stress-strain curve 분산과 상항복점의 Stress 값의 표준 편차의 크기로 부터 박막의 안정도를 예상할 수 있었으며, 이 결과로부터 W-C-N 박막은 질소 유량에 따라 박막의 안정도가 변화하는 것을 알았다.
