This study examines how elementary students understand fractions with operations conceptually and how they perform procedures in the division of fractions. We attempted to look into students' understanding about fractions with divisions in regard to mathematical proficiency suggested by National Research Council (2001). Mathematical proficiency is identified as an intertwined and interconnected composition of 5 strands- conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition. We developed an instrument to identify students' understanding of fractions with multiplication and division and conducted the survey in which 149 6th-graders participated. The findings from the data analysis suggested that overall, the 6th-graders seemed not to understand fractions conceptually; in particular, their understanding is limited to a particular model of part-whole fraction. The students showed a tendency to use memorized procedure-invert and multiply in a given problem without connecting the procedure to the concept of the division of fractions. The findings also proposed that on a given problem-solving task that suggested a pathway in order for the students to apply or follow the procedures in a new situation, they performed the computation very fluently when dividing two fractions by multiplying by a reciprocal. In doing so, however, they appeared to unable to connect the procedures with the concepts of fractions with division.

환경 가치 및 환경 영향의 평가과정은 주관적이고 예측에 의존하기 때문에 과학적 합리성의 확보가 제한된다. 그러므로 정보공개를 통한 절차적 합리성의 확보가 필요하다. 본 연구는 환경영향평가의 절차적 합리성 확보를 위한 방안으로, 평가 과정의 정보공개 강화 방안을 모색하고자 한다. 오르후스 협약은 대중의 환경 정보에 대한 접근과 의사결정에 참여할 수 있는 권리를 규정하는 국제 협약이다. 본 연구는 오르후스 협약에서 제시하는 정보공개에 관한 조항을 토대로 10개 지표를 도출하여 우리나라의 환경영향평가 정보공개 제도를 평가하였다. 평가 결과, 정보공개 방향성 및 제공 기반 마련 측면에서 5개 지표를 만족하여 긍정적 결과를 나타냈다. 그리고 정보 활용 근거 및 제공 과정에 대한 4개 지표에서 세부적인 규정 보완이 필요함을 확인하였다. 마지막으로 대중의 이해 가능성 지표를 통해 전문성 비대칭 문제 및 환경영향평가 제도의 정책 수용성 연구의 필요성을 도출하였다.

초등학교에서 교사는 그들이 가르쳐야 하는 수학에 관한 지식 뿐 아니라 그들의 학생들이 미래에 배워야하는 수학에 관한 지식도 풍부하여야 한다. 초등수학의 수와 연산 영역 중에서 초등학교 학생들이 매우 어려워하는 개념 중 하나가 나눗셈 개념이다. 이에 본 연구는 우리나라 초등예비교사 178명을 대상으로, 그들이 실제 교사로서 교육현장에 나서기 바로 이전 시기에 나눗셈 개념에 있어서 적절하게 개념적 지식과 절차적 지식을 관련지어 이해하고 있는지, 나눗셈에서 나누는 수와 나머지와의 관계에 대해 올바르게 이해하고 있는지 등에 관해 알아봄으로써 그들의 수학적 지식의 이해 정도를 살펴보았다. 그 결과, 대부분의 초등예비교사들이 나눗셈에 있어 개념간의 관련성과 단위에 대한 이해가 충분하지 않은 것으로 나타났다.

In this study, we examined the effect of customer satisfaction and switching cost on continuous use intention to suggest how organizations can retain their customers when market growth slows down and competition becomes stronger. We carefully developed and modified survey instruments through a pre-test, and subsequently surveyed 432 dental care users in Seoul and Busan areas. As a result of regression analysis, higher procedural learning switching cost, relational switching cost, and customer satisfaction were manifested in the increased continuous use intention. In contrast, higher financial switching cost and customer satisfaction with insufficient effort for information acquisition led to decreased switching intention. In addition, procedural initial switching cost and residents in Seoul led to increased switching intention. Understanding continuous use intention and switching intention is important for healthcare institutions striving to maintain market position. The findings of this study suggest a paradigm shift from conventional transactional marketing to strategic relational marketing to be effective in the healthcare environment today.

Purpose: The objective of this study is to deepen our understanding of the key factors that determine sustainability in terms of suppliers based on the transactions between suppliers (pharmaceutical companies) and buyers (medical institutions) in the pharmaceutical distribution industry. Research design, data and methodology: Transaction justice factors were derived from three main components: distributive, procedural and interpersonal, five hypotheses were set up. The respondents from the data collected through an online survey are sales staff of pharmaceutical companies. Total of 319 questionnaires are collected and used to verify the hypotheses through the SPSS 22.0 and AMOS 22.0 programs. Results: Justice of transactions perceived by the salesperson of pharmaceutical companies was found to have a significant effect on the relationship commitment. Among them, procedural justice was found to have greatest relative influences. In addition, relationship commitment was found to have a significant effect on sustainability performance. Thus, all hypotheses were adopted. Conclusions: The results of this study, can be used as basic data for the guidelines for fair trade between pharmaceutical companies and medical institutions. In addition, it is expected that the study will have significance in that it examined sustainability through transactions with buyers from the viewpoint of suppliers.

The purpose of this study was to investigate the influence of a cook's understanding about organizational fairness on job satisfaction and business performance at family restaurants in Seoul. Frequency analysis, reliability analysis, factor analysis, and SEM were applied to analyze the data. First, a confirmatory reliability analysis indicated that organizational fairness, job satisfaction, and business performance were sufficient to be used in this investigation. Organizational fairness, job satisfaction and business performance had generally significant relationships by implementing SEM. According to the results, distributive fairness (p< 0.001), procedural fairness (p< 0.05) and interactive fairness (p< 0.05) had positive influence on cook's job satisfaction. Job satisfaction had a positive influence on financial (p< 0.05) and non-financial performance (p< 0.001). Therefore, for the purposes of food-service companies' continuous increases in business performance and competition are generally necessary to suitably manage the fairness of various policies such as job stability, promotions, impartial distribution of salary, bonus and welfare work, and internal marketing.

Mathematical problem solving has become a major concern in school mathematics, and methods to enhance children's mathematical problem solving abilities have been the main topics in many mathematics education researches. In addition to previous researches about problem solving, the development of a mathematical problem solving method that enables children to establish mathematical concepts through problem solving, to discover formalized principles associated with concepts, and to apply them to real world situations needs. For this purpose, I examined the necessity of problem solving education and reviewed mathematical problem solving researches and problem solving models for giving the theoretical backgrounds. This study suggested the problem solving approach based on the intuitive and the formal inquiry which are the basis of mathematical discovery and inquiry process. And it is developed to keep the balance and complement of the conceptual understanding and the procedural understanding respectively. In addition, it consisted of problem posing to apply the mathematical principles in the application stage.

The purpose of this study is to investigate effects of instruction with stories on elementary school students' science learning and memory. For the purpose, this researcher sampled 3 classes in their 3th grade from an elementary school. Out of the three classes, two were designated as the comparative group consisting of 70 students and the other, the experimental group, 32 students. The former group was applied instruction treatment under the 7th national curriculum of education. The other group was instructed with a story book that contained stories students already knew which were somewhat rearranged to comply with contents of a relevant curricular course. Results of the study can be described as follows. First, academic achievement test was made immediately after the treatment to show that the experimental group was significantly higher in scores for memory and understanding in the section of 'Finding Constellations' that the other group. Second, the two groups' academic achievements in relation to the section, 'Finding Constellations' were tested 3 months after the treatment to show that the experimental group was significantly higher in scores for memory and understanding than the comparative group. Such achievements within the groups were tested 3 months after the treatment to find that both of the two groups didn't show statistically significant differences.
