As a current society changes rapidly, both individuals and organizations are challenging to adapt and lead the changes, and innovative behaviors considered as an important factor to enhance performance and competitiveness. Particularly natural science students have been criticized due to low level of creativity and innovativeness. The purpose of this study was to investigate the structural relationship among psychological capital, creative personality, learning orientation and innovative behavior for natural science students. Data was collected from 255 students in the college of natural science in Korea. Structural equation modeling analysis was employed to test the proposed model and causal relationships among the research variables. As a result, the proposed model was acceptable with a good fit. The results showed that psychological capital had a direct effect on the creative personality and learning orientation, and creative personality and learning orientation had a direct effect on innovative behavior. Furthermore, creative personality and learning orientation played a significant mediating role between psychological capital and innovative behavior. Implications for enhancing psychological capital, creative personality, learning orientation were discussed based on the findings. 기업현장에서는 구성원의 혁신행동을 강조하고 있으나, 최근 대졸 신입사원은 업무에 즉각 투입할 정도의 혁신행동 역량을 갖추지 못하고 입사한다는 비판이 제기됨에 따라 대학의 인재양성에 대한 변화가 요구되고 있다. 이에 본 연구는 자연계열 대학생들의 혁신행동에 영향을 미치는 요인을 파악하고 이를 증진시킬 수 있는 대학교육 방안을 제안하고자 대학생의 심리자본, 창의성향, 학습지향성을 혁신행동에 영향을 미치는 핵심변인으로 선정하고, 변인 간의 구조모형을 상정하여 이들 간의 관계를 규명하였다. 경기도 소재 A대학 자연계열 대학생 255명을 대상으로 자료를 수집하여 구조방정식 모형으로 분석한 결과, 심리자본, 창의성향, 학습지향성은 혁신행동 강화에 직접적인 영향을 미쳤으며, 심리자본은 창의성향과 학습지향성을 매개로 혁신행동에 간접적인 영향을 미치는 것으로 나타났다. 본 연구를 통해 자연계열 대학생을 위한 혁신행동에 영향을 미치는 요인들의 영향력을 실증적으로 확인할 수 있었으며, 이를 바탕으로 혁신행동 강화를 위한 대학교육의 혁신방안을 제안하였다.

Teachers’ STEAM teaching competency determines the success of the STEAM curriculum. The purposes of this study are to analyze factors related to pre-service teachers’ STEAM teaching competency and to identify how to strengthen their STEAM teaching competency in teacher education. While the existing literature has considered STEAM teaching competency as theoretical knowledge, this study explored STEAM teaching competency in the aspects of thinking, attitudes, and practices. Three factors that predict pre-service teachers’ STEAM teaching competency were examined: learners’ backgrounds, participation in extracurricular activities, and participation in thinking-centered learning activities. This study collected data from 238 pre-service teachers from four universities in the Seoul metropolitan area. Welch-Asprin Test, Kruskal-Wallis H Test, and multiple regression analysis were conducted to verify the research questions. Results indicate that there was no statistically significant difference in the STEAM teaching competency in terms of learners’ background factors (i.e., gender, grade, major, and experience with the STEAM curriculum). In addition, only student interactions, study group activities, and learning activities in class showed significant predictive power on STEAM teaching competency. Participation in extracurricular activities showed higher predictive power than participation in thinking-centered learning activities. However,self-development activities and out-of-school activities were not significant factors. Drawn from the key findings, we suggest some directions and strategies for improving pre-service teachers’ STEAM teaching competency in teacher educationprograms. 본 연구는 예비교원의 STEAM 교수역량에 관련된 요인을 분석하고, 교원교육 차원에서 어떻게 STEAM 교수역량을 강화해야 할지 방안을 모색하고자 하였다. 본 연구는 STEAM 교수역량을 이론적 지식차원에서 접근했던 기존의 연구에서 나아가서, 사고방법 및 태도 그리고 실천적 측면에서 STEAM 교수역량을 탐색하고자 하였다. 예비교원의 STEAM 교수역량을 예측하는 요인으로 학습자 배경요인, 비교과활동 그리고 사고력 중심 학습활동 참여의 세 가지를 선정하여, 이들 간의 영향력을 살펴보았다. 본 연구는 수도권 및 지방의 4개 대학(사범대학 2, 교원대학 2)의 예비교원 238명을 대상으로 설문을 수집하였다. 연구문제를 검증하기 위해, Welch-Asprin Test, Kruskal-Wallis H Test, 다중회귀분석을 실시하였다. 분석결과, 학습자 배경요인(성별, 학년, 전공계열, STEAM 교육과정 이수경험)에 따른 STEAM 교수역량은 통계적으로 유의한 차이가 없었다. 또한 STEAM 교수역량에 비교과활동 중 다양한 배경의 학생간 교류, 학습스터디 활동과 수업 중 학습활동만이 STEAM 교수역량에 유의한 예측력을 보였으며, 비교과활동이 사고력 중심 학습활동보다 높은 예측력을 보여주었다. 반면, 비교과활동 중 학교 외 활동과 관련된 자기계발 활동, 대외경험은 유의미하지 못하였다. 분석된 연구결과를 바탕으로 예비교원의 STEAM 교수역량 증진을 위한 교원교육의 개선방안을 제안하였다.

As teamwork is considered to be a critical factor in modern organizations and society, there is a growing body of literature that teamwork for college students needs to be developed and managed. Therefore, the purpose of the present study was to examine the effects of college students’ extracurricular participation and interactions outside of the classroom (peer interaction and student-faculty interaction) on teamwork competency. Particularly, this study targeted students majoring in natural sciences because the previous studies reported that they tended to show a relatively low level of in their communication skills and interpersonal skills compared to other college students. Therefore, data were collected from 567 college students majoring in the natural sciences. The results demonstrated that getting involved in extracurricular activities during college, particularly participation in social clubs and academic-related study groups, had a significantly positive correlation with the development of teamwork competency. Furthermore, peer interaction and student-faculty interaction positively influenced teamwork competency. The findings suggest that encouraging students to participate in social activities and in a major-related learning community would promote teamwork competency. The findings also underscore the importance of peer interaction and student-faculty interaction on the development of teamwork skills and capability. Practical implications were presented to college administrators to develop students’ teamwork competency.

This study was to examine the differences in child abuse experiences among the levels of home economy and family atmosphere perceived by Mongolian children. A total of 250 students in grades 6, 7, and 8 of A Middle School in Tuv aimag Zuunmod hot participated in this study. The scales used in this study were the scale measuring the demographic characteristics of the participants, the scale of the levels of home economy, and the scale of experiences of child abuse. The questionnaires in Korean were translated by a Mongolian expert in translation and underwent a verification process, and data were collected through Mongolian surveyors. The frequencies, means, and standard deviations of the collected data were obtained and two-way ANOVAs and Scheffe t-tests were performed using SPSS 25.0 to verify differences in experiences of child abuse by level. As a result of the analysis, as for the levels of home economy and family atmosphere perceived by Mongolian children, the effects of interactions and the main effect of the levels of home economy on the child abuse experience were shown to be not significant while the main effect of the family atmosphere level was shown to be significant. When concretely examined, the levels of family atmosphere perceived by the children were three levels; not peaceful, moderate, and peaceful, and these three levels showed significant differences in all three subtypes of physical abuse experience, emotional abuse experience, and neglect experience, and the overall child abuse experience. In addition, it was found that the group of children who perceived their family atmosphere as 'not peaceful' had more experiences of all kinds of abuse. Discussion and implications were presented based on the study findings. 본 연구는 몽골 아동학대에 관한 연구로서, 가족 요인인 가정경제와 가정분위기의수준에 따라 아동학대경험에 차이가 나는지를 알아보기 위한 연구이다.

Background/Aims: This study was aimed to investigate the current clinical status of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) in Korea based on a National Health Insurance (NHI) database between 2011 and 2014. Methods: The claims data of ESD for EGC in Korean NHI were reviewed using material codes of Health Insurance Review and Assessment Service between November 2011 and December 2014. The current clinical status was analyzed in terms of treatment pattern, in-hospital length of stay (LOS), total medical costs, and en bloc resection rate according to the hospital type. Results: A total of 23,828 cases of ESD for EGC were evaluated. ESD was performed in 67.4% of cases in tertiary care hospitals, 31.8% in general hospitals, and 0.8% in hospitals, respectively. The median LOS was 5 days, and total median medical costs was approximately 1,300 US dollars. En bloc resection rate was 99%; 8.5% of cases underwent additional treatment within 90 days ESD, and 5.5% in 91 to 365 days after ESD. The clinical status was not significantly different according to the year and hospital type. Conclusions: A majority of ESD for EGC were performed in tertiary care hospitals in Korea. The clinical status showed excellent clinical outcomes and did not differ by the year and between the types of hospitals in Korea.

Inhibitory Effect of 2-Arylbenzofurans from the Mori Cortex Radicis (Moraceae) on Oxygen Glucose Deprivation (OGD)-induced Cell Death of SH-SY5Y Cells

이학주,류다현,구억,이성진,홍성수,김계목,김경호,이동호,마응천 대한약학회 2011 Archives of Pharmacal Research Vol.34 No.8

Three known 2-arylbenzofurans, moracin P (1), moracin O (2) and mulberrofuran Q (3) were isolated from the MeOH extract of the Mori Cortex Radicis. These compounds 1-3 enhanced cell viability in dose-dependent manner against oxygen-glucose deprivation (OGD)-induced cell death in neuroblastoma SH-SY5Y cells, which was measured by MTT reduction assay. (EC50 values of 10.4, 12.6, and 15.9 μM, respectively). In addition, the compounds 1-3 were examined for their inhibitory effect on OGD-induced ROS production by FACS analysis. We observed these compounds reduced ROS production in OGD-induced cell death (IC50 values of 1.9, 0.3 and 12.1 μM, respectively). Consequently, reactive oxygen species (ROS) were overexpressed in OGD-induced cells and all three compounds reduced ROS induced by OGD in dosedependent manner. Taken together, compounds 1-3 might protect neuronal cell death against the oxidative stress induced by OGD, though further studies in vitro and in vivo models are necessary.
