This study analyzes the characteristic of elementary science-gifted education winner programs in Gifted Education Database (GED) focusing on scientific creativity. For this purpose, an analysis framework to analyze the programs was developed and a total of 840 inquiry activities from 55 winner programs were analyzed according to the analysis framework. The analysis of the results reveal that 'scientific inquiry skill' of the five scientific creativity components was most frequently included in the activities. 'Scientific knowledge content' and 'creative thinking' were also frequently included. However, 'problem solving ability' and 'common factor' were a little included. In the aspects of integration, the integrations between two or three components with five or eight types were frequently found. No integrations were also frequently included although less than the previous categories. The integrations among four with four types or five components were also slightly found. 'Scientific knowledge content', 'scientific inquiry skills', and 'creative thinking' with other components were more frequently found. However, the integrations of 'common factor' or 'problem solving ability' with the other components were less frequently found. Educational implications of these findings are discussed.

기업에서는 경쟁력을 강화하고 지속적인 경쟁우위를 확보하기 위한 수단으로 ERP시스템을 도입하여 활용하고 있는 추세이다. ERP시스템은 전체업무프로세스를 정보기술로 구현한 전사적인 통합솔루션이다. 이러한 ERP시스템 구축의 성공요인에 대해 많은 연구들이 진행되어 왔다. 그러나 대부분의 선행연구들은 기술적인 측면 등 외부적인 요인들을 강조하고 있으며, 내부적인 요인인 조직구성원들의 개인적인 성격유형이 ERP시스템의 정보기술을 수용하는데 미치는 영향에 대한 연구는 거의 이루어지지 않고 있다. 본 연구는 ERP시스템 구축의 성공요인으로 조직구성원들의 개인적인 성격유형을 탐색적으로 연구 하였다. ERP시스템 도입기업의 사용자들을 대상으로 MBTI 성격유형과 ERP시스템에 대한 정보기술 수용 정도를 설문을 통해 분석하였다. MBTI 성격유형은 Myers의 네 가지 성격유형으로 측정하고, ERP시스템의 정보기술수용에 대해서는 Davis의 TAM 모형을 이용하였다. 본 연구의 결과는 첫째, MBTI 성격유형과 ERP시스템의 정보기술수용과의 관련성 검증에서 MBTI 성격유형 중 외향형과 판단형인 경우에는 ERP시스템의 정보기술수용에 유의적인 영향을 미치는 것으로 나타났다. 그러나 감각형과 사고형인 경우에는 유의하지 않은 것으로 나타났다. 둘째, ERP시스템 관련 정보기술수용 검증에서는 선행연구들을 통해 검증된 바와 같이 ERP시스템에 대한 지각된 이용 용이성과 유용성, 활용의도 및 활용정도 간에 유의적인 영향을 미치는 것으로 나타났다.

The purpose of this article is to analyze some problems of the present curriculum of social studies education and develop a newer hierarchical curriculum system for the 7th Curriculum Reformation in the primary and secondary school of Korea. Most of the major problems of social studies education come from the mixture of different subject matters without reasonable education logic. Most of teachers feel some difficulties in teaching the social studies for the lack of other subject knowledges. For the better teaching, it is needed to control the integrating level according to the learner's intellectual ability from the elementary school to high school. So, it is necessary to enhance students' thinking skills by their own ability of restructuring knowledges from all subject matters in more advanced curriculum. Also, it is required to develop a new hierarchical system of curriculum concerning the geographical view of the world. Students can have many kinds of geographical view points if teachers can well organize learning activities logically for the students to enhance their understanding of geography by adjusting scale of regional unit, geographical theme, and resolution level of interpretation. And then, in the elementary school curriculum, the students are required to understand the spatial variation of places, and various environments in the world, scale. In the junior high school, students have to understand the relationship between man and nature in the context of large scale environments. The high school curriculum needs to be focused on the student's understanding of the spatial contexts of places by theoretical application in the smaller scale region different from elementary and junior high school curriculums.

In this study, we conducted an exploratory investigation of the imaginative writing processes of middle school students. Twelve 8th graders were asked to imagine and write about the daily life of atoms, assuming that they became specific atoms for themselves. The think-aloud method was used to investigate students' writing processes. We recorded students' writing processes, and also collected the data through interviews to clarify ambiguities in their writing processes. The analyses of the results revealed that their imaginative writing processes could be classified into the three types by the two aspects of writing process components (retrieving information and generating ideas). That is, the integration of retrieving information and generating ideas, the predominant retrieving information, and the predominant generating ideas. The students who were classified into the type of the integration of retrieving information and generating ideas came up with a story and properly introduced science concepts into it. These suggested that this type of students expressed their own understanding more effectively, and that this type was most appropriate for imaginative writing in learning science. The results also showed that the imaginative writing processes were greatly influenced by whether the planning step was adequately considered or not. On the bases of the results, we suggest the teaching strategies for effective imaginative writing in learning science.

In-vehicle warning information systems(IWIS) is an effective countermeasure for preventing traffic crashes. It provides drivers with warnng messages about upcoming hazards to draw proper evasive maneuvering. This study developed a methodology for evaluating the effectiveness of IWIS based on an integrated index to identify driver's responsive behavior. The proposed index consists of characteristics of longitudinal and lateral behavior of vehicle maneuverings. Also, a method to assign mixed-weights in the context of multi-criteria decision making framework was adopted to develop the evaluation method. It is expected that the outcome of this study is useful in designing more effective in-vehicle warning information systems.

The purpose of this study is to find out the characteristics of elderly pedestrian accidents and to suggest policy implications to enhance the level of elderly pedestrian safety. Although much efforts has made to enhance traffic safety environment, pedestrian traffic accidents among elderly population are not significantly decreased. This is mainly because current traffic safety measures do not much consider the characteristics of elderly pedestrians in the aspects of physical and psychological conditions. Main findings from vehicle-pedestrian traffic accident data and survey are as follows. First elderly pedestrians have high probability of traffic accident near crosswalks or cross streets rather than on crosswalk or cross streets. Second they need more green light time for crossing the streets. Third, they feel motor cycles running on the side walk and parked vehicles on the side walk are the most dangerous factors. Forth, general drivers do not have reasonable understanding for the walking behaviors of elderly pedestrians. Fifth, elderly pedestrians frequently need to rest while walking. Sixth, elderly people do not see clearly or understand traffic signs. Finally, many elderly pedestrians experience accidents or inconvenience while walking on the sidewalk.

This study aimed at finding points of improvement in teaching expertise by analyzing the question patterns that appeared during teaching demonstrations which applied science teaching models prepared by a pre-service biology teacher. The question analysis frame for analyzing question types were categorized largely into the question types of Category 1 (questions in cognitive domain, questions with research function, questions in affective domain), Category 2 (repeated questions, questions for narrowing the range, practice questions), and Category 3 (questions on student activity progress, memory questions, and thinking questions). The results of analyzing question patterns from five different science teaching models revealed a high frequency of questions in the fields of cognition and memory. For the circular learning model, questions from the cognitive field appeared the most often, while, student activity progressive questions in particular were used mostly in the 'preliminary concept introduction stage' of the circular learning model and the 'secondary exploratory stage', in which experiments were conducted, and displayed the characteristics of these stages. The discovery learning model combined the courses of observation, measurement, classification and generalization, but, during teaching demonstrations, memory questions turned up the most, while the portion of inquisitive function questions was low. There were many questions from the inquisitive learning model, and, compared to other learning models, many exploratory function questions turned up during the 'experiment planning stage' and 'experiment stage'. Definitional questions and thought questions for the STS learning model turned up more than other learning models. During the change of concept learning model, the five concepts of students were stimulated and the modification of scientific concepts was very much aided by using many memory questions.
