Developing pedagogical content knowledge (PCK) has been emphasized for teacher's professionalism and it should be done from systematic teacher training courses. In this study, we investigated changes of elementary pre-service teachers' PCK of science teaching and motivational strategies before and after a training course. For the analysis of pre-service teachers' PCK, their lesson plans, surveys, and interviews were collected. According to the results, in the beginning of the semester, pre-service teachers in the experimental group usually used didactic or combination of didactic and inquiry teaching strategies and a few pre-service teachers used inquiry or discovery teaching strategies when making lesson plans. However, at the end of the semester many pre-service teachers used inquiry teaching strategies in their lessons which included activities of asking students' prior knowledge, conducing experiments, finding conclusion, and comparing teachers' explanations with students' explanations. Regarding motivational strategies, in the beginning of the semester they focused using activities to create student's emotional interest in science lesson but at the end they used other strategies to create positive atmosphere for learning, capture intellectual interest in science, and connect science to students' everyday lives. The changes in pre-service teachers' PCK in the experimental group was meaningful because there was less change in pre-service teachers' PCK in the control group. This study implies the need for effective professional development programs for developing pre-service teachers' PCK.

The purpose of this study was to examine whether the new introduction of elementary science experiment specialist is appropriate under the current situation of serious emphasis of the importance in science experiments in elementary science in Korea. For this study, the survey items were developed twice through the preliminary study. The results show that most elementary teachers consider the importance of experiment in elementary science and the critical role of science experiments to increase students' curiosity and scientific understanding. About 80% of the teachers stressed the professionalism in elementary science. Although 65% of the teachers believed their having basic professionalism, 53% of them appealed the difficulty in teaching science experiments to students. Nevertheless, 67.5% of the teachers opposed to the idea of teaching elementary science in separation between experiment and theory in science, and only 8% of them agreed the idea of induction or adoption of the college graduates majoring in science and engineering, or holding the secondary teacher's certificate. Further, over 60% of the teachers responded no necessity of inducing the new policy of elementary science specialist. Many numbers of teachers revealed their serious worries about the new policy because of their past experience to suffer from the side effects of inducing the teachers with secondary teacher certificate to the elementary school. In particular, they also made a proposal to make a good use of the current system of exclusive elementary science teacher in Korea. The educational implication and suggestions for policy making were discussed.

The purpose of this study is to analyze the cause-and-effect relationships among positive verbal expressions from family members, social network, and disability identity as the determinant factors of intention to work. To achieve the goal, 453 persons with disabilities and with experiences of using facilities for the disabled were studied, who were recruited for the national survey of domestic violence in 2010. For the research subjects, the cause-and-effect relationships among the major factors were examined by using a structural equation model. According to the results, disability identity and intent to work tended to be higher as they had experienced more of positive verbal expressions from their families. Moreover, a more participation in social activities increased disability identity, but not intent to work. Lastly, disability identity was found to be a determinant of intent to work. Based on the results, we provide suggestions to achieve social inclusion of people with disabilities by raising the intent to work.

The purpose of this study is to understand the life experience of youth who discharged from out-of-home-care and lived as the unemployed NEET(Not in Education, Employment or Training) youth not established in life. For this study, we collected in-depth interviews with five youth in career moratorium or early discharge from out-of-home care. The results of the study were as follows: we divided into six themes such as "I cannot lean on family of origin", "unstable life", "strayed by wandering and prejudice", "I need someone to rely on", "belated regrets", and "constantly dreaming of resurgence"; and the six themes were analyzed separately in the sub-categories. As a result, we found out that the youth in career moratorium lived a life of regret and recovery in the unstable life journey. Based upon the results, we suggested social welfare practice and policy implications in order to systematically support the NEET youth after discharge from out-of-home-care.

The purpose of this study is to understand the mediating effect of self-leadership in the process of understanding the effects of nursing job performance and job satisfaction in the nursing work environment perceived by nurses. In this study, nurses who worked for more than one year at three general hospitals located in Province A. Total of 225 data were used for the final analysis. Date analyzed using the SPSS 22.0 program by t-test, ANOVA, Pearson's correlation coefficient and hierarchical regression analysis. Self-leadership was found to play a partial mediating role in the relationship between nursing work environment and nursing job performance(z=4.30, p<.001) and between nursing work environment and job satisfaction(z=3.70, p<.001). Therefore, in order to improve nursing job performance and job satisfaction, it will be necessary to establish a management plan that can improve the nursing work environment and improve self-leadership.

The main purpose of this study was to examine the correlation between the consumption of red ginseng-based 'SSR' for 30 days and the reduction in human fatigue, blood component changes, and immune cell activity in 35 human subjects. 'SSR' is composed of zinc oxide, folic acid, and D-α-tocopherol with red ginseng as the main component. According to the protocol criteria of the study, 35 subjects who understood the purpose of the study and signed an informed consent form were selected. The fatigue survey was conducted through a questionnaire, and after taking 'SSR', a decreased tendency of physical, mental, and neurosensory fatigue was observed. In hematological analysis, no significant changes were observed in the levels of WBC, RBC, and hemoglobin; however, AST (SGOT) and ALT (SGPT) levels were statistically significantly decreased. In immunological analysis, it was observed that the proliferative effect of T cells (CD3+CD4+) was greater than that of NK cells (CD16+CD56+). The collected data were subjected to t-test analysis using the SPSS 25.0 statistical program. The result from this study proposes that 'SSR' can be used as a functional food material as it reduces human fatigue and enhances immune function.
