The purpose of this study is to analyze Korean students' mathematics achievement characteristics and draw implications for better math education in schools through comparing the results of three east Asian top level countries, Korea, Singapore, and Japan in PISA 2012 results. As a results, the rate of correct answers of Korea students was relatively low compared with those of Singapore, but relatively higher than Japan. From the results of effect size, similar results from t-test was discovered. As shown in analysis according to sub-elements in math assessment framework, the Korean students had low effect size in every sub-elements than Singapore. and they had high effect size at most of sub-elements than Japan, except "personal" context. In top performing level(above level 5), the Korean students had high effect size at "quantities" in mathematical contents, and "employ" in mathematical processes compared with Singapore. And they had row effect size at 6 sub-elements compared with Japan.

The purpose of this study was to examine present condition of social work field education, students' stress/stress coping strategies in their field practicum, and to find out the difference according to the factors related field education. This study carried out a survey targeting 202 students who finished their social work field practicum and took their course work in 2012, from 4 different universities in the northern Gyeonggi province & Seoul. As the result, in the area of stress, the highest rank was the lack of professional knowledge/skills, the second was the environment of field practicum, and the third was the burden of tasks that they had to perform. About the coping strategies, it was found that students utilized 'problem-solving focused' the most, pursuing 'social support' as the second, and 'avoidance' strategies as the least. Factors influencing on differences of stress level depending on field work experiences were whether they had previous field experience, how much time they participated in previous volunteer activities, whether they attended orientation for their field practicum, regularity/frequency of supervision, the satisfaction on their social work/welfare major, and the satisfaction on their field practicum or supervision. Based on the results, suggestions for development in field education system were presented.

This study was designed to create a situational and procedural simulation of web-courseware which will enhance students' self-directed learning styles during the economics class in elementary schools. When teaching the students how to be wise consumers, it is important to provide them with various experiences that will lead them to make active and rational decisions. Actual experiences are, however, rather limited in reality which consequently result in learning economics only vicariously at school. The purpose of the study was, therefore, to develop a courseware which allows the student to have indirect experiences through computer simulations. The courseware will not only assist the student in making decisions and taking actions appropriately during the various situations given in the program, but also overcome the limitations of the classroom setting by using the procedural simulation.

21세기를 맞이하는 기업은 세계화와 국제화, 정보의 다양화 및 분산화, 제품수명주기의 단축과 수익률의 감소, 고품질의 제품, 지식산업의 등장, 고객 욕구의 증대 등 다양한 내 ${\cdot}$ 외적 환경변화에 대응해야 하고 경쟁우위를 확보하기 위해 끊임없이 기업의 변화능력을 확보해야 한다. 기업은 제품을 생산하여 판매하는 기업의 시스템 전체가 경쟁력을 갖추어 총체적 우위를 확보하고 고객의 기호와 감성에 호소하는 제품을 만들 수 있도록 다양한 정보를 제공하는 시스템을 필요로 하게 되었다. 즉, 시간과 서비스에 뒤진 고객지원체계는 기업의 성장에 절대적인 마이너스 요인이므로 고객 정보의 효율적 관리, 고객 요구에 대한 신속한 대응, 정기적 고객만족도 조사 등 고객이 원하는 것을 재빠르게 얻어낼 수 있는 고객 친밀형 정보시스템의 확립이 요구되는 것이다. 이를 해결해 줄 수 있는 새로운 경영정보시스템이 바로 WebERP인 것이다. WebERP는 기업의 원활한 자재, 구매활동을 위해 제안된 MRP에서 시작되었으며, 생산관리의 개념을 포함하고 있는 MRPII로 확대되었다가 다시 인사나 회계, 재무 등 조직이나 기업의 전업무영역을 수용하는 종합경영정보시스템으로 발전된 것이다. 현재는 전자상거래와 관련하여 WebERP의 필요성이 부각되었고, 모기업과 협력사간의 구매발주 및 납품관리를 확대시켜 소모성자재(MRO: Maintenance, Repair & Operation) 및 기타 공동구매서비스와 유사업종간의 그룹을 형성하여 ASP(Application Service Provider)의 공동 환경을 이용한 WebERP 환경을 이용한 WebERP활용이 현시점으로 적실히 필요한 것이다. 이는 중소기업들의 공동 협업체제를 도모하여 외세를 대비하는 응집력을 확고히 함으로써 집단체제의 e마켓플레이스 확립과 더불어 국제경쟁을 대비한 방안으로서 집단 공동의 웹환경 인프라가 필요한 것이다. 이러한 배경에서 ASP환경을 이용한 WebERP활용방안과 시스템 구축전략을 경남지역의 기계산업정보화사업단이 추진하는 일반기계, 전기기계, 금속기계, 수송기계, 정밀기계의 5개 업종을 4,877개 기업 대상으로 추진하고 있으며, 그 중 WebERP의 모델로서 2003년도까지 50개 기업을 선정하고, 이는 5개 업종 골고루 선정하여 적용과 표준화 모델로 전개해 나가는 것을 정리한 것이다.

The purpose of this study is to develop a measurement tool for the quality of information commons. Information commons is a physical, technological, social, and intellectual place where library users can experience various educational, research, and cultural activities. It is recently gaining popularity and several libraries have implemented it to help users share knowledge and interact with each other. It also intends to provide a place for collaboration, learning, and rest. Despite its benefits and usefulness, there is no measurement tool explicitly designed for the quality of information commons. This study used in-depth personal interview, compared prior studies, and conducted a pilot study to elicit library users' perceptions on information commons and factors influencing on the perceived quality of information commons. Groups of initial items were emerged through classifying and clustering key concepts in the data. Then, the validity of the items were verified through a pilot study. The findings of this study will be useful for developing more reliable and valid survey measurement tool.

In This Paper, I call Johnson & Lakoff (1980; 1999)'s Experientialism or Experiential Realism or, Embodied Realism, Nunez(1995; 1997)'s Ecological Naturalism as Experientialism and try to investigate the possibility of their Experientialism to be a philosophy of mathematical education. This possibility is approached in the respect with the problem of objectivism and relativism. I analyzed the epistemological background of embodied cognition first and then mathematical epistemology of experientialism. Experientialism shares its Philosophical position partly with Dewey and Merleau-Ponty. Experientialists deny the traditional hypothesis of philosophy as such separability of subject and object, and of body and rationality and also They have better position of epistemology than that of Hamlyn, and of Social Constructivism. Therefore, They guarantee wider range of mathematical universality than Hamlyn and Social constructivist. I conclude that the possibility of Experientialism to be a philosophy of mathematical education depends on the success of its supporting the practical study on mathematics education.
