Objective: The aim of this study was to investigate the clinical significance of myocardial injuries in patients with nontraumatic intracranial hemorrhage by identifying the occurrence of myocardial injury and defining its correlation with subsequent cardiovascular events. Subjects and methods: One hundred twenty-four patients with nontraumatic intracraninal hemorrhage presented to the emergency department within six hours from onset of symptoms were enrolled. Brain CT, serial electrocardiography, and echocardiography were done at the emergency center. Blood samples for troponin I and creatine kinase(CK)-MB were drawn immediately and eight hours after admission, Troponin I and CK-MB were measured using a chemiluminescent immunoassay, respectively. Results: Electrocardiographic and echocardiography abnormalities were found in 65 cases(52.4%) and 21 cases(17%), respectively. Serum troponin I and creative kinase-MB were increased in 35 cases (28.2%) and in 58 cases(46.8%), respectively. Abnormal findings of echocardiography and ECG, as well as elevated levels of serum troponin I and creative kinase-MB, were associated with an increased risk of cardiovascular event and survival. Logistic regression analysis revealed that an abnormal echcocardiographic finding and elevation of serum troponin I were factors associated with the occurrence an adverse cardiovascular event and that electrocardiographic abnormalities and initial mental status were factors associated with poor prognosis. Conclusion: This study reveals that actual myocardial injury develops in a significant proportion of patients with nontraumatic intracranial hemorrhage and that the development of the myocardial injury is associated with an adverse cardiovascular event that occurs during admission.

Walter Byers, the NCAA Executive Director from 1951 to 1987, coined the term 'student-athlete' in 1973. This phrase has since become widely recognized on college campuses and within society, and implies dual and separate role of being both a student and an athlete. As the term implies, these individuals attend college for two main reason: to make progress towards a college degree and to participate in intercollegiate athletics. The purpose of this study was to investigate factors influencing role conflict on personal attributes, athletic performance and role salience among collegiate student-athletes. The sample was drawn from 821 student-athletes who involved in intercollegiate athletics at the university located in Seoul and Kyunggido and enrolled in Korea Sports Council. They were selected by the method of stratified cluster random sampling. A survey was undertaken from 2003, using the self-administration method. All of questionnaires were personally delivered to the respondents, who immediately filled them out. t-test, one-way ANOVA, multiple regression were used to test and analysis the proposed model in the study. The findings of this study were as follow: 1. Female athletes shows greater cognitive and empirical status role conflict and load conflict, cognitive self role conflict, and empirical student-athlete role conflict than male athletes, three years athletes shows greater cognitive and empirical student-athlete role conflict than any other years athletes, and athletes with high level of life shows cognitive self role conflict and empirical student-athlete role conflict than any other athletes with love of life. 2. Athletic success influence cognitive self role conflict, and playing career has effect on empirical student-athlete role conflict. 3. Relative knowledge related in role of student and athlete has effect on all of cognitive and empirical role conflict, relative time spent in role of student and athlete has effect on cognitive status role conflict, cognitive and empirical load role conflict, and empirical student-athlete role conflict. And relative values of role of student and athlete has effect on cognitive and empirical status role conflict, cognitive and empirical load role conflict, empirical self role conflict and empirical student-athlete role conflict, and relative devotion in role of student and athlete has effect on cognitive self role conflict. status role conflict, load role conflict, and student-athlete role conflict, And satisfaction with student role has effects on cognitive self role conflict, and empirical status role conflict and load role conflict.

본 연구에서는 산불 피해 소나무재의 이용을 위한 기초자료를 얻고자 역학적 및 건조 특성을 조사하였다. 산불피해재는 종압축 특성, 전단강도, 충격휨흡수에너지 등에서 건전재와 거의 유사한 결과를 보여주었으며, 산불피해재 변재부의 휨특성은 건전재보다 양호하게 나타났다. 건전재와 산불피해재 변재부의 생재함수율은 산불피해재가 다소 낮았으나, 건조속도는 거의 차이가 없었다. 건조시 발생되는 초기할렬은 건전재가 산불피해재보다 발생율이 높았고, 내부할렬은 건전재와 산불피해재에서 발생되지 않았다. 따라서 산불에 의해 피해를 입은 목재의 대부분은 수피부를 제거하여 이용할 경우 건전재와 거의 동일한 용도로서 사용이 가능할 것으로 생각된다. The Mechanical and drying characteristics of Pinus densiflora wood, which was damaged by forest fire, and sound wood were examined. There were no significant differences in axial compressive properties, shearing strength and impact bending absorbed energy between damaged and sound woods. But the bending properties of damaged wood were slightly higher than those of sound wood. The green moisture content of sapwood in damaged wood was lower than that in sound wood, but oven-drying rate was similar in both woods. Number of initial check in damaged wood was smaller than that in sound wood, and inner check in damaged and sound woods was not observed. Consequently, it is considered that mostly damaged wood by forest fire can be used for wood material after removing the considered that mostly damaged wood by forest fire can be used for wood material after removing the bark.

<P>Zika virus (ZIKV) (genus <I>Flavivirus</I>, family <I>Flaviviridae</I>) is an emerging pathogen associated with microcephaly and Guillain-Barré syndrome. The rapid spread of ZIKV disease in over 60 countries and the large numbers of travel-associated cases have caused worldwide concern. Thus, intensified surveillance of cases among immigrants and tourists from ZIKV-endemic areas is important for disease control and prevention. In this study, using Next Generation Sequencing, we reported the first whole-genome sequence of ZIKV strain AFMC-U, amplified from the urine of a traveler returning to Korea from the Philippines. Phylogenetic analysis showed geographic-specific clustering. Our results underscore the importance of examining urine in the diagnosis of ZIKV infection.</P>

교과외 활동이 교육수요자의 학교만족도에 미치는 영향

전구훈(Gu-Hun Jeon),김희찬(Hee-Chan Kim) 한국콘텐츠학회 2018 한국콘텐츠학회논문지 Vol.18 No.4

본 연구는 교과외 활동인 창의적 체험활동, 생활지도, 상담활동이 교육수요자인 학생과 학부모의 학교만족도에 미치는 영향을 검증하고, 학교만족도를 높이기 위한 실천적·정책적 대안을 제시하는데 목적이 있다. 이를 위해 서울시에 거주하는 초·중·고등학생 1,242명과 학부모 1,023명을 대상으로 설문을 실시한 뒤 설문내용을 바탕으로 t검증, 회귀분석을 수행하였다. 세 가지 주요한 분석결과를 도출했다. 첫째, 교과외 활동은 학교만족도에 정적인 영향을 미치는 것으로 나타났다. 둘째, 일반적으로 한국의 학부모는 높은 교육열로 입시위주의 교육과정을 강조할 것으로 생각되었으나 학생과 학부모 두 집단 모두 교과외 활동이 강화될수록 학교만족도가 높아지는 것으로 나타났다. 셋째, 학교 급별로 학교만족도에 차이가 있는 것으로 나타났는데 학교 급이 올라 갈수록 학교만족도가 낮은 것으로 나타났다. 교육수요자인 학생과 학부모의 교육만족도를 높이기 위해서는 교과외 활동이 필요하다는 것을 알 수 있다. 또한 고학년인 고등학교에도 지금보다 교과외 활동을 보강할 필요가 있다. The purpose of this study is to examine the effects of extracurricular activities such as creative experiential activities, life guidance, and counseling activities on school satisfaction of students and parents who are educational demanders, and to suggest practical and policy alternatives to improve school satisfaction. For this purpose, 1,242 elementary, middle and high school students in Seoul and 1,023 parents were tested through analysis of t-test, and regression. Three main results were derived. First, extracurricular activities had a statistically significant effect on school satisfaction. Second, in general, parents in Korea are expected to emphasize the entrance examination-oriented curriculum with a high degree of education, but the higher the extracurricular activities of students and parents, the higher the school satisfaction. Third, there was a difference in school satisfaction by education class, but the higher the education level, the lower the school satisfaction was. It can be seen that extracurricular activities are needed to increase the educational satisfaction of students and parents who are educational demanders. In addition, it is necessary to reinforce the extracurricular activities to the high school which is the upper grade school now.
