최근에 정보통신기술(ICT)이 교육과정에서 다양한 내용을 지도하는데 중요한 도구로 등장하였다. 본 논문에서는 자기조절 학습전략 수준에 따른 ICT 활용수업 모형이 정보활용 실천력에 미치는 영향을 검증하였다. 실험집단을 3개로 구성하고 ICT 활용수업 모형인 문제해결학습, 토의학습, 정보탐색학습 수업을 적용하였다. 실험 도구로는 자기조절 학습전략과 정보활용 실천력 설문지를 사용하였으며, 자기조절 학습전략 설문지로 사전검사를 실시하고 정보활용 실천력 설문지로 사전 및 사후 검사를 실시하였다. 실험에서 자기조절 학습전략 수준이 높은 집단이 낮은 집단보다 정보활용 실천력이 높게 나타났으며, 이외에도 다른 훙미로운 결과들이 나타났다.

For the purpose of adapting positively to the information society, it is very important to develop the capabilities of the retrieve, gather, process and application for informations by making efficient use of computers. So, with a view to understanding the importance of computer and adjusting actively to the information society, the systematic policy to cultivate the ability of making the most of computers is strongly demended. Therefore this study is to make a curriculum and guide for improving the capability of applying computers systematically, through analyzing a curriculum of computer in Elementary, Middle and High Schools, and to develop a model of grading system to cultivate the ability of applying computers, which grades capabilities of its practical use.

With the continuous development and progress of science and technology, the field of mixed reality applications has involved scientific research, medicine, entertainment, education, information dissemination, and people's daily lives; This paper will focus on the application of mixed reality in the field of education and teaching, relying on the characteristics of mixed reality technology. This article will use the combination of mixed reality and smart glasses to fully consider the characteristics of photography darkroom teaching, design and produce a mixed reality photography darkroom teaching software, and explore the feasibility of the application of mixed reality in teaching. This paper will use literature research methods, practical research methods, and survey methods as the main methods of research topics to determine the importance, feasibility, and necessity of the relevant theories studied in this paper. The application of mixed reality technology in photography darkroom teaching can not only solve many problems in the existing darkroom teaching methods, but also develop and expand students' Independent learning ability. It is concluded from this that mixed reality teaching software has the feasibility of sustainable development, which brings particular application value to the development and research of other education and art discipline software.

Web application security education that can provide practical experience is needed to reduce damage caused by the recent increase in web application vulnerabilities and to strengthen security. In this paper, we proposed a scenario-based web application education method, applied the proposed method to classes, and analyzed the results. In order to increase the effectiveness of scenario-based education, a real-life practice environment to perform scenarios and instructions to be performed by learners are needed. As an example of the proposed method, instructions to be performed by learners from the viewpoint of the attacker and the victim were shown in a practice environment to teach XSS and SQL injection vulnerabilities. After applying the proposed method to the class for students majoring in cyber security, when the lecture evaluation results were analyzed, it was shown that the learner's interest, understanding, and major ability all improved.

The fault-tolerance routing problem is one of the most important issues in the application of the Internet of Things, and has been attracting growing research interests. In order to maintain the communication paths from source sensors to the macronodes, we present a hybrid routing scheme and model, in which alternate paths are created once the previous routing is broken. Then, we propose an improved efficient and intelligent fault-tolerance algorithm (IEIFTA) to provide the fast routing recovery and reconstruct the network topology for path failure in the Internet of Things. In the IEIFTA, mutation direction of the particle is determined by multi-swarm evolution equation, and its diversity is improved by the immune mechanism, which can improve the ability of global search and improve the converging rate of the algorithm. The simulation results indicate that the IEIFTA-based fault-tolerance algorithm outperforms the EARQ algorithm and the SPSOA algorithm due to its ability of fast routing recovery mechanism and prolonging the lifetime of the Internet of Things.

Character recognition has already been studied in a lot of fields. But, if input-characters have noise in practical application system, the ability decreases markedly. Special consideration should be taken into account in the recognition of blurred data. This paper proposes low-quality printed character recognition methods that extracts blurred parts of the character image, deletes them and carry out accurate character recognition.

Backround : The paradigm of recent education has been shifting from existing style of professor-oriented, passive and rote teaching to learner-centered education. Rather than mere delivery of knowledge, today's idea of education uses various audiovisual media to let learners gain more problem-solving skills, judgment, cognitive thinking ability, and creativity to apply to real practice. Also, while current trends and change in policy ask for related industry to require practice-centered teaching learning model, Problem-Based Learning (PBL) is quite effective that it activates problem-solving skills as well as application of National Competency Standards (NCS). Purpose : The purpose of this study was to suggest a teaching learning model article as an approach to apply web-based PBL for patient & medical charge management practices. Discussion & Conclusion : This paper the cases on PBL and presents the teaching learning model on web-based PBL as an approach to applying web-based PBL, which fits Medical Information System Department that combines health-medical treatment and computer applications, to practical health administrative affairs.

This paper proposes a security platform, called SCAP(Security platform for CORBA based APplication), to cope with potential threats in a distributed object system. SCAP supports CORBA security specification announced by OMG. SCAP is comprised of four functional blocks, which co-work with ORB to provide security services: Authentication Block, Association Block, Access Control Block, and Security Information Management Block. It is designed to support Common Secure Interoperability Functionality Level 2, which is useful for large-scale intra-, or inter-network based applications. Actual security services, which are dependent on supporting security technology, will be provided as external security service for replace ability. Implementation issues such as how to simulate an interceptor mechanism using a commercial ORB product without source code, and how to extend Current object required for security services are also described. At the end of the paper, the SCAP applied to the web environment is described to show its practical utilization.

교육인적자원부는 ICT 활용 교육을 주도해 나가는데 가장 중심이 되는 교사의 ICT 활용 능력을 신장시키기 위해 다양한 방안들을 수립하여 추진하고 있다. 그러나 현재 시행되고 있는 교사의 ICT 활용능력 신장에 관한 대부분의 노력들은 ICT를 직무활동에 효과적으로 활용할 수 있는 능력보다는 기술소양 능력에 중점을 두고 있다. 그러므로 본 논문에서는 교사의 직무활동을 분석하고, 국내외 교사 ICT 활용능력 평가도구를 비교 분석하여 교사의 ICT활용능력 자기평가 도구를 개발하였다. 또한, 개발된 웹 기반 교사의 ICT 활용능력 자기평가도구를 광주와 전남 지역의 교사를 대상으로 적용하여 성별, 직위별, 지역별, 교육경력별 ICT 활용능력 수준 등을 조사분석하였다.
