  • The purpose of this study is to develop a survey tool of scientific character for elementary student which connects science education and character education effectively by figuring out traits of elementary students' character being presented in teaching and learning context of elementary school science. For this, we adapted the theocratical model from the previous research which defined scientific character as the competencies being able to practice in concrete teaching and learning context of science. Based on this model, we developed the survey tool as 'Scientific Character Inventory for Elementary Student' to assess elementary students' scientific character as the competences to practice the virtues being pursued in the context of elementary school science and verified its reliability and validity. As a result of an exploratory and confirmatory factor analysis, we confirmed all the items could be summarized into 28 items and eight constructs such as scientific problem-solving, self-management, self-reflection, communication, interpersonal skill, community participation, global citizenship, and environmental ethics awareness. We found that minimum reliability coefficient of constructs was over than 0.5 and reliability coefficient of the total items was 0.878. And also, there was modest relationship between each construct and the total score of scientific character. These results show that the developed survey tool can be useful in evaluating the effectiveness of science character education. This study is meaningful in that it systematically reveals constructs of scientific character which can be raised in concrete context of science teaching and learning so as to suggest the survey tool to assess this.

  • 공유하천유역에서의 수자원 관리는 두 국가의 제도적 및 기술적 차이로 인하여 다른 유역에서의 수자원 관리보다 복잡하고 어렵다. 특히 두 국가 사이의 공유하천에서의 유량의 변화는 실질적인 측정을 이용하여 면밀하게 측정됨으로써 신뢰도 높은 자료를 통해 지속적으로 분석되어야 궁극적으로 공유하천에 대한 두 국가 간의 이해관계를 바탕으로 한 대책을 수립할 수 있다. 북한강 유역의 상류유역은 북한에 속해 있고, 특히 임남댐 건설 이후 화천댐 유입량은 지속적으로 감소하고 있어 이에 대한 물순환 영향을 면밀히 분석하고 대책을 수립할 필요가 있다. 물순환에 영향을 미치는 원인과 결과를 분석하는 기존의 연구들은 대부분 강우-유출모형을 사용하고 있어 모형의 구축 및 매개변수의 보정과 검증에 많은 노력이 필요하다. 본 연구에서는 수문기상자료만을 이용하여 유량의 변동성분을 정량화할 수 있는 수문학적 민감도 분석기법을 화천댐 상류유역에 적용하고 화천댐 유입량에 대한 1967년~017년 동안의 변동량을 자연적 요인과 인위적 요인으로 분리하여 제시하였다. 다양한 변동점 탐색기법을 사용한 결과 1999년이 통계적으로 유의한 변동점으로 탐색되었으며, 이를 활용하여 수문학적 민감도 분석을 5가지의 Budyko 함수를 이용하여 산정한 결과 평균적으로 18.99 억 ㎥/y의 유입량 감소가 임남댐 건설로 인하여 발생된 것을 알 수 있었다. 이와 같은 결과는 기존 연구자들의 화천댐 유입량 감소량에 비해 다소 크게 산정된 결과이며, 이는 2000년대 이후 증가된 강우량 및 화천댐유입량의 감소가 주된 영향을 미친 결과로 추정된다. 향후 월별, 계절별 단위의 분석이 추가로 연구될 필요가 있으며, 미래의 기후변화 상황을 고려한 예측을 통한 실효성 있는 계획이 수립될 필요가 있을 것으로 판단된다.

  • This study set out to construct an social capital scale that could be commonly used by social welfare organizations and to apply it to examine any differences in social capital among social welfare organizations. For those purposes, the study distributed a questionnaire by mail to social welfare organizations in 15 cities and provinces across the nation and conducted latent means analysis. The major research findings were as follows. First, as a result of exploratory factor analysis and confirmatory factor analysis, the validity and reliability in measurement indicators of social capital were proved to be satisfactory level. Secondly, social capital were found to be interpreted at the organizational level through the review of levels of analysis. Meanwhile, the configural, metric, and scalar invariance of social capital scale were confirmed, which indicates that the social capital scale can be commonly applied to social welfare organizations. Finally, latent means analysis was carried out to examine differences among social welfare organizations in the subindexes of social capital including network connectivity, setting and sharing of vision, reciprocal norm, trust and cooperation, and group participation. As a result, there were significant differences among social welfare organizations in network connectivity, reciprocal norm, trust and cooperation and group participation but no statistically significant differences among them in sharing of vision, goal and core value. Those findings led to implications needed to manage of social welfare organizations.

  • This study aims to assess the competitiveness of 30 logistics centers that operate in the hinterland of the North Container Port at Busan New Port. Thirty-two key factors were selected from previous studies to analyze and improve competitiveness and expand business opportunities in the hinterland. Suggestions from logistics experts were also canvassed. These variables were then put through first- and second-factor analysis to verify validity and measure confidence levels; they were later categorized into five factors and 15 sub-factors impacting on competitiveness. The categorized factors were compared using the analytic hierarchy process (AHP) to assess the importance of each factor and sub-factor in the case of logistics centers in the North Container hinterland of Busan New Port. The findings indicate that factors related to the securing of significant amounts of container cargoes were of greater importance. On the other hand, relatively basic factors proved to be less important in improving the competitiveness of the port hinterland.

  • The purpose of this study is to develop math anxiety scale for middle school students for planning and implementing math anxiety treatment programs. In this study, we describe the process of developing and validating math anxiety scale for middle school students and detailing exploratory factor analysis and confirmatory factor analysis to verify construct validity. As a result of the study, we developed the Math Anxiety Scale for Middle School Students (MASS-M) of 30 items with four factors: mathematical curriculum content, mathematical attitude, mathematical test, and environment. As a math anxiety factor for middle school students, MASS-M was developed, which includes mathematical anxiety factors such as mathematical test factor and environmental factor, especially mathematical curriculum content factor describing mathematical treatment, and mathematical attitude factor describing psychological treatment. MASS-M, derived from this study, is a standardized scale for measuring math anxiety in middle school students and is expected to serve as the basis for maintaining consistency in research on math anxiety in middle school students and developing programs to treat math anxiety in middle school students.
