Team project learning is a type of Project-Based Learning, which is an effective learning method for developing collaborative competency and interpersonal communication skills, as well as for developing cognitive competency such as critical thinking, creative thinking, and analytical skills. This research, conducted to analyze learning activities, focuses on students' creative thinking and activities in TPBL(Team Project-Based Learning). A qualitative approach including a reflective journal based on the 6 stages of TPBL, was adopted for this purpose. In this study, 69 reflective journals on the three stages (developing a theme, researching, theme-making) of 23 undergraduate students were categorized on the basis of three criteria: divergent thinking factors, convergent thinking factors and affective factors. The results show that the participants' journals demonstrated twenty-eight activities from nine cognitive factors and nine activities from three affective factors were derived from reflect journal. This finding indicates that more appropriate instructional strategies are needed for students to enhance their creative thinking skills and activities

Purpose - This study aims to find if the introduction of project finance perspective leads to any modification to the view of PM industry on CSFs of PPP and their relative importance rank. Design/methodology/approach - Through literature reviews, this study came up with a set of CSFs reflective of both perspectives. AHP method was applied for analysis by developing an Analytic Hierarchical Model from this set and survey questionnaires of pairwise comparison to solicit 46 qualified expert responses. Findings - This study concurs with PM industry to acknowledge 'risk allocation', 'legal framework' and 'quality of feasibility' as ones of most important CSFs. However, relative importance rank of individual CSFs goes through significant modification under this study in favor of 'sponsor commitment and quality' but against 'political environment', in particular. Research implications or Originality - Discussions on the CSFs led by PM industry have not been properly reflective of project finance perspective, which is injected into this study to cure the partiality. For researchers, findings of this study may call attention to financing perspective when they discuss CSFs of PPP. Practitioners may benefit from this study by allocating resources in view of this new finding when pursuing PPP projects.

In this paper we described an approach to automation of visual inspection of solder joint defects of SMC(Surface Mounted Components) on PCBs(Printed Circuit Board) by using neural network and fuzzy rule-based classification method. Inherently the surface of the solder joints is curved tiny and specular reflective it induces difficulty of taking good image of the solder joints. And the shape of the solder joints tends to greatly vary with the soldering condition and the shapes are not identical to each other even though the solder joints belong to a set of the same soldering quality. This problem makes it difficult to classify the solder joints according to their qualities. Neural network and fuzzy rule-based classification method is proposed to effi-ciently make human-like classification criteria of the solder joint shapes. The performance of the proposed approach is tested on numerous samples of commercial computer PCB boards and compared with the results of the human inspector performance and the conventional Kohonen network.

The objective of this phantom study is to develop a digital method for improving the lateral resolution of B-scan ultrasonographic images irs medical application of ultrasound. By utilizing a discrete state-space modeling approach and Kalman-Buch method for analysis of the transducer's beam profile and the measurement and sampling noise, a stable recursive restoration of the object image was obtained for improved lateral resolution. The point spread function (PSF) was measured for the reflective signals after scanning the small pins located along the depth of interest. One major advantage of the present recursive scheme over the transform method is in its applicability for the space-variant imaging, such as in the case of the rotational movement of transducer.

This research suggests science inquiry play of analogy as a teaming method to help the students in concrete operational stage to develop scientific thinking skills and to understand abstract science conceptions. The research focuses on/considers the characteristics and merits of the science inquiry plays, and the learning method by analogical reasoning. This learning through the science inquiry play of analogy can be considered as a meta-model for scientific thinking skill. The learning has the following processes: 1) Students analogize the abstract science conceptions and facts into play-type activities including the concrete contents such as students themselves, their physical-sensory motions, concrete objects, play methods, and play rules. 2) Students as analogized objects play a role physically and sensuously according to the methods and rules analogized in the play. 3) Students find out the concrete contents included in the science inquiry play of analogy, draw the results, and deduce the new conceptions from the results by reflective thinking and analogical reasoning.

과학의 본성에 대한 이해는 과학적 소양의 요소로서 그 중요성이 강조되고 있으며, 우리나라에서는 제5차 교육과정에 과학의 본성에 대한 이해가 과학교육의 목표로 제시되기 시작했다. 학교수업에서도 과학의 본성을 가르치려는 시도들이 이루어졌는데, 우리나라에서는 주로 과학사 소재를 수업에 도입하는 방법에 국한되어 진행되어 왔다. 이외에 과학의 본성을 가르치는데 있어 적합한 방법으로 실험수행을 들 수 있다. 또한, 반성적 접근 방법을 적용한 과학의 본성수업이 제안되고 있는데, 이것을 조합하여 현장에서 보편적으로 이루어지는 실험수업에서 실험에 대한 반성과 토의를 강조하면 학생들이 과학의 본성을 이해하는데 효과적일 것이라 예상하였다. 따라서 이 연구에서는 반성을 강조한 실험수업을 중학생들에게 적용하였고, 과학의 본성에 대한 설문지를 통해 과학실험 활동에서 적극적인 반성과 토의 과정이 과학의 본성의 대한 이해의 증진에 도움을 주는지 알아보았다. 연구 결과 반성을 강조한 실험수업은 관찰과 추론 관계, 자료 해석의 다양화, 탐구와 사회적 제반 상황과의 관련 영역에서 과학의 본성 이해에 특히 효과적이었으며, 그 외 과학적 탐구기능과 과학적 탐구의 사회성 모든 영역에 대한 학생의 이해에 효과적이었다. 연구 결과를 통해 반성을 강조한 실험 수업은 과학의 본성 이해에 효과가 있다고 말할 수 있다.

The purpose of the study is to investigate the effectiveness of the cultural instruction based on the critical pedagogy through film. The participants were 21 college students enrolling 'Understanding American/British culture'class and the class was 15 week long. During class, they discussed and selected the cultural topics related to the movies, complete the research papers, and then gave presentations. The students' portfolio, which consists of the goal statements, research papers, and the reflective journals, was analyzed to investigate the effectiveness of the instruction. The results showed that the instruction was effective in five aspects. They are, 1)accumulation of the cultural knowledge, 2)better understanding of the target culture and its people, 3)acquisition of the critical perspectives toward the target and their own cultures, 4)teaching method, and 5)increase of the motivation for studying other cultures. The study suggested that the instruction should be applied to English-medium class with more advanced students.

Purpose: The purpose of this study was to explore women caregivers' lived experiences in caring at home for a family member with dementia and to identify conditions that oppress women in the context of family caregiving. Method: This study was conducted within the feminist perspectives using qualitative secondary data. Ten secondary data conveying self reflective contents were selected from the 25 original data obtained in 1999 to 2000. Result: Six themes that emerged from the qualitative thematic content analysis were; androcentric view of family caregiving, undervalued family caregiving by the family members, Self rationalization in the context of family caregiving, family-centric care mechanism, exemplary caring within the family context, and inter-familial relationships among women. Conclusion: The main focus of feminist research is to provide empowerment for the women, research participants and to bring about social change of oppressive constraint through some actions. On the basis of the research findings, therefore, action strategies from feminist perspectives were suggested in some aspects of health care delivery sectors, nursing education and research sectors, and administrative sectors.

본 논문에서는 CAVE$^{TM}$-like 시스템에서 시각 커뮤니케이션 지원을 위한 고화질 스테레오 비디오 아바타 생성 기법을 제안한다. CAVE$^{TM}$-like 시스템에서는 사용자를 둘러싸고 있는 스크린으로 투사되는 빛의 잦은 변화 때문에 비디오 아바타 생성에 필수적인 사용자 추출이 쉽지 않다. 본 연구에서는 가시광선 차단 필터를 부착한 흑백 카메라로 획득된 적외선 반사 영상을 이용함으로써 스크린 상 빛의 변화를 차단하여 강건하게 사용자를 추출할 수 있도록 하였다. 또한, 사람의 양안차 간격으로 배치한 두 대의 컬러 카메라를 사용하여 삼차원 기하 정보의 재구성 없이 고화질 비디오 아바타를 빠르게 생성하고 입체 디스플레이 하기 위한 양안용 사용자 영상을 획득하였다. 획득된 영상에서 배경을 제거하기 위하여 적외선 반사 영상으로 정의된 실루엣 마스크와의 피팅 알고리즘을 제안한다. 생성된 비디오 아바타 스테레오 영상은 가상공간 내 평면 상에 텍스처 매핑하여 프레임 순차 스테레오 방식를 이용하여 입체 디스플레이할 수 있도록 하였다. 제안된 방식은 기존의 3D 비디오 아바타보다 고화질의 결과를 빠르게 생성할 수 있으며, 2D 기반 방식에서 제공해주지 못하던 입체감을 제공해준다.
