This paper investigates the relationship between the structural characteristics of a virtual CoP and the measures of social network analysis. Several implications were developed by the results of the study First, the study, based on reviews of both the CoP and SNA literature, identified specific structural measures of SNA; connectedness, geodesic distance, and density. Second, the formal CoP investigated in this study showed greater development that the classic, informal CoP in terms of the structural dimension of a CoP. The results show that those measures of social network analysis provide an illuminating way to better understand the structural properties of CoP's. Implications of the study with some suggestions for future research are provided.

이 연구의 목적은 실행중심 무용교육의 패러다임에 관한 비판적 접근을 바탕으로 무용교육학의 학문적 정체성을 탐색하는 것이다. 한국의 무용교육은 1955년 교육부에서 고시된 제1차 교육과정 이후 학교무용으로서 65년의 역사를 지니고 있음에도 무용교육학으로서의 학문적 정체성이 견고하지 못하다. 전통적인 무용교육은 실행중심 패러다임에 따라 지나치게 교사중심, 실기기능중심, 연습중심으로 운영되었다. 그러나 최근 학교, 지역사회, 전문 분야에서 무용교육학은 새로운 패러다임 구축을 요구받고 있다. 이에 이 연구는 시계열 관점의 키워드 네트워크 분석을 실시하여 무용교육연구의 각 구간별 주요 내용을 검토하였다. 연구결과, 무용교육연구는 5개의 구간으로 구분되었다. 제1구간(1968~1979)은 체육학을 기반으로 한 무용교육의 실천, 제2구간(1980년~1989년)은 초등교육을 위한 창작 기반의 움직임 교육, 제3구간(1990년~1999년)은 교급별 무용교육과정의 체계화, 제4구간(2000년~2009년)은 문화예술교육 패러다임의 등장, 제5구간(2010년~2019년)은 교육실천과 학제의 다양화가 이루어졌다. 연구결과를 바탕으로 복합학으로서 무용교육학, 학제간 실천 및 연구를 지지할 수 있는 학문적 정체성을 정립할 수 있는 노력이 요청된다.

Owing to the limits of IT System-driven knowledge management(KM) for innovation processes, alternative KM methods has been suggested such as: (1) the knowledge network of experts or (2) communities-of-practice. This study analyzes two cases in terms of on-line expert knowledge networks for problem-solving, with the dimensions of analysis based on a theoretical framework. By analyzing the cases of S company's expert network and Naver's Ji-sik-iN, we found that system quality(e.g., ease of use, accessibility, and searching function), information/knowledge quality(e.g., usefulness, accuracy, and timeliness), knowledge-sharing culture, social capital and relevant reward systems are important for stimulating a Q&A-based problem-solving knowledge network. Implications of the findings and future research directions are discussed.

이 연구의 목적은 행위자-네트워크 이론이 과학교육 연구에 주는 시사점을 도출하는 것이었다. 이를 위해 최근 국내외의 교육 분야의 연구에서는 어떻게 행위자-네트워크 이론을 적용해왔는지를 중심으로 선행연구를 분석하였다. 연구 결과 교육 분야에서 행위자-네트워크 이론을 적용한 교육 연구들은 크게 세 가지 접근방식으로 분류되었다. 첫째, 교육 방법이나 관점을 구성하기 위한 인식론적 관점으로 활용하거나 둘째, 비인간의 행위성을 인식하는 존재론적 관점으로 활용하거나 셋째, 교육 연구를 위한 방법론으로 활용 또는 제안하였다. 연구 결과를 토대로 과학교육 연구에의 기여 가능성을 논의하였다. 새로운 이론적 관점으로써 행위자-네트워크 이론이 과학교육의 실천과 연구에 있어 함의를 줄 수 있을 것으로 기대한다.

In this research, we create a network infrastructure based on a service-oriented infrastructure (SOI) for the virtualization technology and integrate it with a cloud technology that applies the cloud integration management platform (CIMP) concept. In CIMP, the server and storage will be separated. The server will be adopted for virtualization while the storage will be used by students and teachers to store data. As long they save their data in the storage module, every time, everywhere, and on every device, they can access their data. This research will implement the design of the network infrastructure and be applied to the remote practical learning system in the laboratory. Students and teachers will ultimately adopt this network infrastructure for remote practice using their respective devices without physically meeting in the laboratory. In the future, if the implementation phase is successful, then in addition to laboratory environments, it can be implemented in all learning activities at our campus.

본 논문에서는 컴퓨터네트워크 실습 교과목을 대상으로 한 전문대학 학습자에 적합한 PBL 교수 학습 모형의 설계 및 구현을 다룬다. 설계된 교수학습 모형은 대덕대학 2학년 학생들을 대상으로 진행하였다. PBL 수업에 참여한 학생들은 PBL 학습을 통해 문제 체계적으로 진행된 수업에 대한 만족을 나타냈으며 과제 해결을 위해 자료와 도구를 적절히 이용하는 능력을 향상시켰으며 협동학습을 통해 더 많은 것을 배울 수 있었다. 이를 학습자의 수업평가 결과를 통해 확인하였다.

An antivirus is a widely used solution for detecting malicious softwares in client devices. The performance of antivirus solutions in the mobile client environment is critical due to its resource constrains. Many solutions light-weighting client's overhead in the mobile client environment have been developed. However, most solutions require platform modifications or software installations and it decreases their realizations in practice. In this paper, we propose a solution detecting malwares on networks using the Software Defined Network (SDN). Our main goal is designing a solution detecting malwares of mobile client without involving the client into the work. We contribute to provide a solution that does not require client-side installations or modifications and so is easily applicable in practice.

Existing network cryptography systems are threatened by recent developments in quantum computing. For example, the Shor algorithm, which can be run on a quantum computer, is capable of overriding public key-based network cryptography systems in a short time. Therefore, research on new cryptography systems is actively being conducted. The most powerful cryptography systems are quantum key distribution (QKD) and post quantum cryptograph (PQC) systems; in this study, a network based on both QKD and PQC is proposed, along with a quantum key management system (QKMS) and a Q-controller to efficiently operate the network. The proposed quantum cryptography communication network uses QKD as its backbone, and replaces QKD with PQC at the user end to overcome the shortcomings of QKD. This paper presents the functional requirements of QKMS and Q-Controller, which can be utilized to perform efficient network resource management.

In oncologic practice, treatment guidelines provide appropriate treatment strategies based on evidence. Currently, many guidelines are used, including those of the European Association for the Study of the Liver and European Organization for Research and Treatment of Cancer (EASL-EORTC), National Comprehensive Cancer Network (NCCN), Asia-Pacific Primary Liver Cancer Expert (APPLE), and Korean Liver Cancer Study Group and National Cancer Centre (KLCSG-NCC). Although radiotherapy is commonly used in clinical practice, some guidelines do not accept it as a standard treatment modality. In this review, we will investigate the clinical practice guidelines currently used, and discuss the application of radiotherapy.

The purpose of this study was to find out the characteristics of the direct workers and the organizations delivering services to the children in low-income families, and to identify major factors that affect the number and degree centrality of service network. The research sample was 141 organizations. and the data were collected by a survey questionnaire and analyzed by UCINET V and multiple regression. The results show that the classification of organizations, the work-autonomy, the license of social welfare have a significant effect on the number of network organization, and the license of social welfare, the subjective body of organizations, the number of children in charge have a significant effect on the degree centrality of service network, among the independent variables. Based on the research results, implications for the future practice are discussed.
