최근 의학교육은 의과대학에서 의학전문대학원으로의 체제변화와 의사국가고시 실기시험 도입에 따른 변화에 대처해야하는 과제를 안고 있다. 따라서 의학전문대학원 학생들의 특성을 고려하고 국가고시 실기시험을 대비한 임상수행능력향상을 위한 교육이 필요하다. 본 연구는 의대생들의 스트레스, 자아탄력성, 자기효능감에 따른 임상수행능력과의 관계를 알아보기 위한 서술적 상관관계 연구로 D시에 소재한 일 의학전문대학원생 97명을 대상으로 2011년 8월19부터 20일까지 설문조사를 실시하였다. 연구결과는 스트레스는 자아탄력성과는 부적상관관계를 나타냈었고 자기 효능감의 하부영역인 자신감과는 정적상관관계를 보였다. 자아탄력성은 임상실기수행능력의 하부영역인 CPX와는 정적상관관계를 나타내었다. 자기효능감의 하부영역인 과제난이도 선호는 OSCE와 부적상관관계를 나타내었고, 임상실기수행능력의 하부영역인 OSCE와 CPX는 정적상관관계를 나타내었다. 따라서 학생들의 스트레스 감소는 자아탄력성을 향상시킬 수 있으며 궁극적으로 임상실기수행능력을 향상시킬 수 있다고 본다. 이상의 결과로 볼 때, 임상실기수행능력 향상을 위해서는 학생 개인의 특성을 파악하여 자아탄력성 향상을 위한 교육프로그램을 개발하고 교육과정에 반영하여야 할 것이다.

본 연구는 한국 성인의 식습관과 정신건강과의 관련성을 규명함으로써 올바른 식습관 형성의 중요성을 알리고 한국인의 정신건강증진을 위해 기초자료를 제공하는데 그 목적이 있다. 연구 대상자는 국민건강영양조사 5기(2010-2012)에 참여한 19세 이상 성인 15,848명(남자 6,348명, 여자 9,500명)을 대상으로 하였다. 자료분석에서 일반적은 특성은 기술분석을 활용하였으며, 식사와 정신건강과의 관련성은 카이제곱검정을 실시하였다. 그리고 다중 로지스틱 회귀분석과 선형경향성을 사용하여 식습관과 정신건강과의 관련성을 파악하였다. 연구결과, 남성은 식사횟수가 증가할수록 스트레스와 자살생각이 감소하는 경향을 보였다. 그리고 여성은 식사횟수가 증가할수록 스트레스, 우울, 자살생각이 모두 감소하는 경향을 보였다. 특히, 여성은 1식에 비해 2식을 할 경우 스트레스가 0.667배 감소하였다. 그리고 1식에 비해 3식을 할 경우 스트레스는 0.522배, 우울 0.605배, 자살생각 0.508배 감소함을 규명하여 식사횟수가 정신건강에 영향을 미치는 것을 확인할 수 있었다. 결론적으로 규칙적인 식습관이 정신건강에 영향을 줄 수 있기 때문에 올바른 식습관과 그로 인한 균형 잡힌 영양소 섭취가 정신건강에 중요함을 알리는 교육과 사회적 관심이 필요하다.

The purpose of this study was to obtain the information of the home treatment state for children with delayed development and to identify stress and coping pattern in mothers of the children. Data were collected from 211 mothers of delayed developmental children(DDC) by means of structured questionnaires. The results of this study were that in the home treatment mothers had technical insufficiencies to treat their children. so they had a difficulties in treating their children at home. But the home treatment were effective and mothers were assisted by their family and others in their treatment. The mothers had stress by anxiety of prognosis. hurts, responsibility, technical insufficiencies and negligent in housework. And acquisition of home treatment technique, the existence of assistant, and emotion in treatment also influenced on stress in the mother. The coping pattern in the stress were regular medical examination. communication with medical team and other mothers with DDC, faith of recovery and treatment. confidence in home treatment, family coorperation. and leisure time without concern for treatment. The younger mother received the more help from other mothers with DDC. And the mothers with severe, complex DDC had the more help from faith of recovery. Regular medical examination and faith of recovery were helpful coping pattern in mothers who had no treatment skill. Confidence in family coorperation and leisure time without concern for treatment were particularly helpful in mothers whose treatment duration is longer, and home treatment was not effective.

BACKGROUND/OBJECTIVES: This study examined the association of depressive symptoms, stress perception, and suicidal ideation with overall dietary quality using the newly developed Korean healthy eating index (KHEI). SUBJECTS/METHODS: This study included 9,607 adults (3,939 men and 5,668 women, ≥ 19 years) who participated in the 6th Korea National Health and Nutrition Examination Survey 2013 and 2015. The KHEI scores were calculated using the food frequency questionnaire data. Survey logistic regression analyses were performed to analyze the association between psychiatric distress and dietary quality. RESULTS: The percentage of subjects with experience of depressive mood, higher stress perception, and suicidal ideation was 8.2%, 25.0%, and 3.7% in men and 15.4%, 27.3%, and 6.0% in women, respectively. The mean KHEI score was 61.5 ± 0.29 in men and 64.8 ± 0.24 in women (P < 0.001). The present study found a difference in the adherence to specific dietary components of the KHEI between sexes. Men experiencing depressive symptoms were less likely to eat meat, fish, eggs, and beans, while depressed women showed lower vegetable intake. Both men and women with suicidal ideation showed a lower intake of vegetables. The men with stress had a lower breakfast eating score than those without stress (7.21 vs. 6.77, P = 0.016). The multivariate-adjusted odds ratios for depressive symptoms, stress perception, and the suicidal idea in women with the highest quartile of KHEI scores compared to the lowest quartile was 0.69 (95% confidence interval, 0.51-0.92), 0.73 (0.58-0.82), and 0.52 (0.33-0.82), respectively and significant dose-response associations were observed (P for trends < 0.05 for all). On the other hand, these associations were not observed in men after adjusting for the confounding variables (P for trends > 0.05 for all). CONCLUSIONS: Poor adherence to dietary recommendations is associated with psychological distress, especially in women.

The high temperature fatigue tests were performed using the specimens taken from Cr-Mo-V steel, widely used as thermal power plant turbine materials for examination fatigue behavior of materials in power plants which have been operated for long periods. The fatigue tests at high temperature were performed at the various temperature and applied stress. The results obtained are summarized as follows : The fatigue crack length increases and the fatigue life decreases with temperature and applied stress according to the same number of stress cycle. The fatigue crack propagation and the fatigue life were much influenced by temperature and applied stress.

If the load of constructing vehicles during the construction work acts on the road or the ground surface on the soft ground, due to the excess stresses in soils the trafficability of the vehicles influences the constructing efficiency, constructing period and so on. Stress distribution in soils is the very important element to design and to solve the problems of settlement, safety of foundations and trafficability of constructing vehicle in civil engineering. This research represents the comparative estimation of the actual and theoretical measurement on the underground stress of outer layer for each soil after the observation of each top soil layer for its vertical and horizontal stress in (1)homogeneous sand ground (2) weak stratum with the sand soil (3) weak stratum with gravel of the soil model, and it also investigates the effect of subsidence of ground by the repeated load. The underground stress turn out to be different in the value of theoretical and actual measurement after the trial examination of model.

Since the pre flex beam is fabricated by welding, the precompressive stresses that should occur over the concrete pier are diminished by the welding residual stresses. Therefore the welding residual stresses must be relieved during the fabrication. So the analysis and examination of the accurate welding residual stress distribution characteristic are necessary. On this study, accurate distribution of welding residual stress of preflex beam is analyzed by finite element method.

Design details pertaining to the connection between some recently developed fiber reinforced polymer (FRP) composite deck systems and the supporting girders require openings through cells of the deck. This significantly changes the stress distribution in these components. As a result, the conventional assumptions that deck designs are controlled by their stiffness, and not strength, needs a closer examination. This paper proposes an analytical method to investigate the stress states and failure mechanisms using a type of "global-local" modeling perspective, incorporating classical lamination theory and first ply failure criterion with use of appropriate stress concentration factors around the cutouts. The use of a "smeared-stress" approach is presented as a potential means of simplifying certain FRP specific complexities, while still enabling prediction of overall failure.

Purpose: The main purpose of this study was to explore the influences of adolescents' smoking on the stress level according to gender. Methods: We used the data from the 2008 Korea National Health and Nutrition Examination Survey conducted by the Korea Centers for Disease Control and Prevention between the period of Jan. and Dec. 2008. The target population of this study is 805 adolescents in the 12~19 years old. Results: 22.0% of male adolescents and 11.8% of female adolescents were current smokers. Hierarchical regression analysis showed that stress level was associated with self-reported health status, drinking, and smoking among males. Among females, stress level was associated with BMI. Conclusion: The results of this study would help to develop smoking prevention programs and health promotion strategies for adolescents.
