누구에게나 질 높은 강의를 무료로 수강할 기회를 제공하겠다는 MOOCs의 야심이 전통적인 교육방식에 변화를 불러일으키고 있다. 현재 대부분의 MOOCs 강의는 고등교육 수요자를 대상으로 하고 있지만 본 연구에서는 그동안 언급된 MOOCs의 장단점을 분석해서 고등학교에서 효과적으로 MOOCs를 활용할 방안을 탐구하였다. 그 결과, 전공 탐색의 기회와 학생부종합전형 활동자료로 활용하거나, 플립러닝 형태의 수업에서 강의자료로 활용하며 고교학점제의 시행에 따른 학생 선택 과목 확대에 대비하는 방안을 제안한다.

본 논문은 클라우드 컴퓨팅 시스템의 필수적인 보안 요구사항에 대해 분석한다. 클라우드 컴퓨팅은 수 많은 자료와 방대한 자원을 다루는 시스템이다. 클라우드 컴퓨팅은 이와 같은 특징으로 인해 쉽게 해커의 공격 대상이 된다. 따라서 클라우드 컴퓨팅 산업에서는 무엇보다도 보안이 매우 중요한 요소이다. 본 논문에서는 잠재적인 위협으로부터 클라우드 컴퓨팅이 보유한 자료와 자원을 보호하기 위한 필수적인 보안 요구사항에 대해 분석한다.

Various visualizing methods have been proposed according to the input and output types. To show complex and large-scale raw data and information. LOD and special region scale method have been used for them. In this paper, I propose level scale interface for dynamic and interactive controlling large scale data such as bio-data. The method has not only advantage of LOD and special region scale but also dynamic and real-time processing. In addition, the method supports elaborate control from large scale to small one for visualization on a region in detail. Proposed method was adopted for genome relationship visualization tool and showed reasonable control method.

Recent trend in petroleum/gas exploration is an application of 3D seismic exploration technique. Unlike the conventional 2D seismic data processing, 3D seismic data processing is considered as the one which requires expensive commercial software systems and high performance computer. This paper propose a practical 3D seismic processing methodology on a personal computer using public domain software such as SU, SEPlib, and SEPlib3D. The applicability of the proposed method has been demonstrated by successful application to a well known realistic 3D synthetic data, SEG/EAGE 3D salt model data.

Regression models were obtained on the base of the correlation between Phytophthora blight incidence in red pepper and the microclimate data obtained from automated weather station (AWS) during 1997 and 1998. A computer program (PEPBLIGHT) was constructed based on the model that the R2 value is highest among regression models. This computer program uses the microclimate data from more than one AWS through the common dialogue box easy and it is able provide disease forecasting information. In addition, it could be applied far other diseases and converts the microclimate data of AWS to the input data for Statical Analysis System (SAS). PEPBLIGHT was first developed for the forecasting computer system of red pepper blight in Korea. PEPBLIGHT is operated on the MS Windows, so that it is easy to use.

In the environment of emphasizing creativity, computer application instruction model is in demand which is developed for the group discussion, enlarging the range of thinking, and creativity. The purpose of this study is to develop a PBL-based computer application instruction model concerning creativity after researching problems during the use of computer education by group. The theoretical background of class model is PBL, and the efficiency and creativity of class is considered while using web-mind map as the tool for the discussion and data sharing. As a result of applying the suggested model to the students enrolled in the production of presentation instruction, it made probabilistic meaningful outcome where complaint with communication, data sharing, role sharing, difference of contribution, excessive run-time and etc. were reduced.

CS Unplugged education at the base of computer science is emphasized as an instrument for teaching the basic principles of elementary SW education, but these materials for elementary education are very lacking. So We'll present the data error detection and correction materials for elementary school classes. Based on previous studies related to this topic, we developed learning materials for elementary higher grade students using Hamming code. We introduces the card magic in the introduction part. 'error detection and correction' learning materials based on the principle of Hamming code, were composed as activity-based education. The results of the questionnaire survey showed that it had a positive effect on improving learners' understanding of computer science.

Computer Forensics functions by defending the effects and extracting the evidence of the side effects for production at the court. Has the faultlessness of the digital evidence been compromised during the investigation, a critical evidence may be denied or not even be presented at the trial. The presented monograph will deliberate the faultlessness-establishing chain procedures in disk forensics, system forensics, network forensics, mobile forensics and database forensics. Once the faultlessness is established by the methods proposed, the products of investigation will be adopted as a leading evidence. Moreover, the issues and alternatives in the reality of digital investigation are presented along with the actual computer forensics cases, hopefully contributing to the advances in computer digital forensics and the field research of information security.
