In conclusion, the systemic environment was shown that negative environment was being created to deepen conflict, and the conflict processes could be changed in either positive or negative directions by the psychological environment and psychological resolution mechanisms proposed afterward. As the result that the psychological environment was improved into aggressive mood with constant communication effort with the interested parties, the psychological resolution mechanism was also presented in the suitable forms of aggressive communication. On the contrary, if developed psychologically negative environment, the psychological resolution mechanism was also negatively affecting the conflict processes with dogmatic and consistent response rather than flexible response suitable to the situations.

In this study, the influences of the context of discrepant events on the conceptual change process using cognitive conflict strategy were investigated in terms of students' cognitive and motivational variables such as cognitive conflict, situational interest, attention, effort, conceptual understanding. A preconception test was administered to 536 seventh graders. A test of response to a discrepant event and a situational interest questionnaire were then administered. The context of discrepant events, either scientific or everyday, was randomly presented to the subjects. After learning the concept of density, the tests of attention, effort, and conceptual understanding were administered. The reponses of 194 students who had been found to possess the target misconception were analyzed. The results revealed that the scientific-context discrepant event induced higher cognitive conflict than everyday-context one. The context of discrepant events, however, did not show significant correlations with situational interest, attention, effort, and/or conceptual understanding. The result of path analysis indicated that the context of discrepant events both directly influenced cognitive conflict and indirectly influenced conceptual understanding via cognitive conflict.

In this paper, we develop a Spatio-Temporal graph as of a key component of our knowledge representation Scheme. We design an integrated representation scheme to depict not only present and past but future in parallel with the spaces in an effective and intuitive manner. An event in general occupies not only a space but a time. Hence a crucial premise for the simulation of virtual situations is to position events in the multi-dimensional context, that is, 3-D space extended by the temporal dimension. Furthermore an event tends to have physical, social and mental aspects intertwined. As a result we need diverse information structures and functions to model entities and relations associated with events and to describe situations in different stances or perspectives of the virtual agents. These structures and functions are implemented in terms of integrated and intuitive representation schemes at different levels such as Ontology View, Instance View, ST View, Reality View. The resulting multi-dimensional comprehensive knowledge structure accommodates multi-layered virtual world developing in the time to maximize the diversity of situations in the historical context. The viability of this knowledge representation scheme is demonstrated with a typical scenario applied to a simulator implemented based on the ST Graph. The virtual stage based on the ST graph can be used to provide natural contexts for situated learning or next-generation simulation games.

정책변화가 왜 발생하였는가? 그와 같은 정책변화에 어떠한 요인들이 작용하였는가? 또한 그와 같은 정책변화가 어떠한 과정을 거쳐서 발생하였는가? 본 연구는 정책변화의 복잡성을 체계적으로 설명할 수 있는 방법을 제시하고자 정책연구의 지배적인 패러다임인 객관적·과학적 연구방법에서 탈피하여 사회적 형성주의 관점에서 맥락, 문제정의 및 대상 집단의 사회적 형성이 정책변화에 어떠한 영향을 미치는가를 알아보고자 하였다. 이를 위하여, 본 연구는 문제정의 이론과 대상 집단의 사회적 형성 이론의 결합을 통하여 연구 모형을 구축하였다. 또한 이와 같이 구축된 모형에 의하여 정책결정자가 문제 정의와 대상 집단의 사회적 형성에 어떤 역할을 하며, 그 결과가 정책변화에 어떻게 반영되는지를 정책의 논리, 근거 및 메시지의 측면에서 양도소득중과제도를 대상으로 분석하였다. 마지막으로, 이러한 분석을 통하여 도출된 시사점에 대하여 논의하였다.

Images have been substantially searched and used due to not only the advanced internet and digital technologies but the characteristics of a younger generation. The purpose of this study aims to discuss the ways on expanding the access points to images by analyzing the needs of users in context of everyday life. In order to achieve the purpose of this study, 105 questions of image seeking in NAVER, which is one of social Q&A services in Korea, were analyzed. For the analysis, a two-dimensional framework with image uses and image attributes were utilized. The findings of this study demonstrate that considerable use purposes on data oriented pole, such as information processing, information dissemination and learning are identified. On the other hand, image attributes from the needs of image show that non-visual aspects including contextual attributes are recognized substantially in addition to the traditional semantic attributes.

The purpose of this study is to analyze the concept of the real number e and to investigate the understanding of pre-service teachers about the real number e. 28 pre-service teachers were asked to take a test based on the various ideas of the real number e and 8 pre-service teachers were interviewed. The results of this study are as follows. First, a large number of pre-service teachers couldn't recognize relation between the formal definition and the representations of the real number e. Secondly, pre-service teachers judged appropriately for the irrationality and the construction impossibility of the real number e, but they couldn't provide reasonable evidence. Lastly, pre-service teachers understood the continuous compounding context and exponential function context of the real number e, but they had a difficulty in understanding the geometric context and natural logarithm context of the real number e.

In this study, we analyzed contextualized NOS lessons planned by preservice teachers from the perspectives of PCK. Eight preservice teachers who had completed all of the curriculum at the College of Education located in Seoul participated in the study. CoRe and teaching and learning guidance were collected. Interviews were also conducted. We used analytical induction to analyze the collected data. The analyses of the results revealed that the NOS learning goals selected by the preservice teachers were different depending on the context of the NOS lessons. In addition, the preservice teachers were unable to sufficiently explain the value of learning NOS. All of the preservice teachers were worried that their students would not understand NOS properly, and they faced various difficulties in dealing with NOS and science content. They thought that if their students conducted experiments, errors could cause problems for students learning NOS. Meanwhile, they guessed their students' preconceptions and misconceptions of NOS based on their experience. The preservice teachers also thought that their students' concept of science and cognitive development stage would affect their NOS learning. Although the preservice teachers used various strategies to teach NOS, NOS was often not explicitly addressed. Also, they were reluctant to evaluate NOS in lessons. Based on the above results, educational implications for preservice teacher education were proposed.

캐나다의 통신시장 자유화 및 경쟁도입은 비교적 늦게 시작되었지만, 지금은 세계 어느 나라보다 경쟁적 환경이 각 분야에서 전개되고 있다. 이는 정부의 정책과 산업계의 활동이 경쟁 강화와 시장확대에 초점을 맞추고 있기 때문이다. 따라서, 캐나다 통신서비스 산업을 이해하기 위해서는 그 근간이 되는 규제측면에서의 이해가 전제되어야 하며, 본 고는 이런 맥락에서 규제기관의 주요 경쟁도입 결정과 그 후속조치로서의 경쟁환경 조성 제반조치 등을 중심으로 최근 10년간의 캐나다 통신서비스 산업 전반을 분석하였다.
