The process of international technical cooperation is quite complex. If the complexity is reduced and mirrored as a simple model, it could be of great assistance to government agencies and staff to support international technical cooperation. The purpose of this paper was to develop the underlying process model in international technical cooperation in the evaluation phase. The paper provides in the second chapter the theoretical background for developing a process model. In the third chapter, the features and the practical model of the evaluation phase are presented. Chapter four presents a case with substantial empirical analysis of the development model. EU FP7th as a case study was examined in the hindsight of international technical cooperation in the evaluation process. The concluding, chapter five, presents the limitations and future research directions. The results show that a new phase can be analyzed on the level of the evaluation step. The limitation of this study was that the empirical study consists of a single case study only. In the future, it will be necessary to study the sub stages of other steps in international technological cooperation.

RFID 미들웨어의 평가를 위한 방법으로서, 테스트 데이터셋을 이용한 시뮬레이션은 일반적으로 사용되는 평가 방법이다. 태그 식별자에 따라 순차생성된 가상 데이터셋이나 랜덤 생성된 데이터셋의 경우 미들웨어의 단순 처리량을 평가하기에는 유용하나 미들웨어의 정확성이나 실행 가능성를 평가하기에는 한계가 있다. 테스트 데이터셋은 실제 리더에서 생성된 데이터셋과 매우 유사하여야 함에도 불구하고, 테스트 데이터셋의 품질 기준이 정의되어 있지 않음에 따라 테스트 데이터셋이 얼마만큼 실제 데이터셋과 유사한 지를 평가하기가 어려운 문제가 있다. 이를 위해 본 논문에서는 RFID 미들웨어의 평가에 사용되는 테스트 데이터셋의 품질을 평가하기 위한 품질 지표를 제안한다. 제안하는 품질 지표는 실제 RFID 리더에 태그가 통과할 때 생성되는 데이터 셋을 기반으로 하여 정의하였으며, RFID 무선 인식의 고유의 특성, 즉 중복성과 불확실성을 수치화해서 표현하는 특징이 있다. 또한 제안한 품질 지표를 실제 RFID 리더를 통해 생성한 데이터셋에 적용하여 비교 검토함으로써 품질 지표의 유용성을 입증한다.

최근의 일상 생활들은 정보통신 네트워크를 기반으로 제공되는 서비스와 밀접하게 연관되어 있다. 지난 1.25 인터넷 대란을 통해서 볼 수 있듯이, 네트워크 침해사고로 인해 네트워크 필수 서비스가 중단되었을 때 사용자를 위해 네트워크 기반으로 제공되는 주요한 서비스에 막대한 피해가 발생한다는 것을 직접 확인하였다. 컴퓨터 네트워크에서 필수 서비스의 가장 중요한 특성 중 하나는 서비스의 연속성이다. 필수 서비스의 연속성이 보장되지 못하게 되면 네트웍의 정상적인 동작에 큰 문제를 야기한다. 따라서 대상이 되는 네트워크가 필수 서비스를 보장하는 능력을 평가하여 안전하고 신뢰성 있는 네트워크 서비스를 제공하기 위한 연구가 필요하다. 본 논문에서는 시뮬레이션 기반 필수서비스의 연속성 평가 방법론을 제안한다. 이를 위해 평가 모델의 구성, 실행, 분석 등의 단계를 가지는 평가 절차를 제시한다. 또한 평가 프레임을 제시하고 프레임의 구조 및 동적 특성을 살펴본다. 마지막으로 서비스 연속성의 정도를 평가하기 위한 평가 지표를 가용성, 권한보호성, 정보비밀성, 복구가능성 등 4가지로 분류하고 각각에 대해 살펴본다.

The survey method was used in this descriptive study. The purpose in this study was to investigate middle school home economics(HE) teachers' stages of concern, levels of use, and perception about career education, based on the Concerns Based Adoption Model(CBAM). Questionnaire was administrated to middle school HE teachers over the whole country except Jeju Island through mail or e-mail by systematic random sampling. 118 data collected from the responses were finally analyzed statistically with mean, standard deviation, frequencies, percentage, and independent-sample t-test by using SPSS/WIN 12.0 program. The results of the study were as follows: First, most-HE teachers were in stages of the personal concern (86.56) and the informational concern(85.42) about HE career education. Second, the highest number of teachers was in level of refinement(33.1%) use. Third, teachers recognized important goal of HE career education as 'understanding of diverse careers and formating of positive values and attitude about work'. Also they had generally conducted HE career education through 'Understanding Teenager' chapter of a first-year middle school. However they had struggled with difficulty such as lack of data, time, and expertise in conducting HE career education. Therefore, it is necessary that support such as development, supplies, and training opportunities of career education should be provided.

The system of teaching culinary practice needs drastic modification to catch up with dietary life and education curriculum changes. To reflect such changes, it is necessary to instill a strong will and interest as well as educational environment improvement in teachers. In this sense, this study researched the teachers' stages of concerns, levels of use, innovation configuration, and intervention demands, based on the CBAM(Concerns Based Adoption Method) developed by Hord et. al. For the survey, 500 questionnaires sent by mail and 187 were analyzed by SPSS/win 10.0 program. The results are summarized as follows. 1) The teachers stages of concerns on culinary practice is assessed to be in the lowest level of perceptual stage, which indicates a state of indifference. 2) In terms of the levels of use, routine use was the highest, followed by refinement use, integrated use, research use, and reinvent use in descending order. Mechanical use posted the lowest level. Even though the stages of concern showed the beginning stage, the Level of use was relatively high. 3) About the innovation configuration, approximately 30% of the teachers were not accomodate the culinary practice referred to the 7th National Education Curriculum. 4) According to the intervention demands on culinary practice education, it was found that teachers generally wanted more interventions in every component. Among the intervention components, the highest demand was on the support for facility. Demand on the financing is the second highest. Teachers in the level of routine use demanded more information and materials supply and individual encouragement, but teachers in the level of preparation needed study opportunity for training on operation skills more.

This study investigated 15 science teachers' perception and practice on free semester and science assessment. We analyzed frequencies of teacher choice for closed questions and used constant comparative method for teacher description and individual interview. Most teachers determined a low ranking for changes in assessment methods and mentioned a lack of objectivity on free semester assessment, unsystematic free semester assessment, and more importance on student activity and interest in science instruction. Most teachers understood process-based assessment as a direction of free semester assessment and teachers mentioned positive aspects for students or teacher difficulties dependent on their perception on process-based assessment. Half of the teachers failed to implement student self-assessment and student peer-assessment due to subjectivity and complexity. Some teachers did not provide feedbacks to students due to a lack of time and did not use certain assessment methods due to a lack of knowledge of the assessment. Teachers who did not have an experience of discussions in a teacher learning community mentioned reasons regarding a small number of the same grade teachers and inactive attitude of colleagues. Teachers who did not participate in professional development programs mentioned a lack of teacher understanding of free semester, participation of the teacher in charge, and teacher choice of participation as reasons.
