Study on Method to activate Computer Assisted Education at Elementary Education Stage
김동준(Dong-Jhoon Kim) 한국컴퓨터정보학회 2009 한국컴퓨터정보학회 학술발표논문집 Vol.16 No.2
The purpose of this study is to allow all of the instructors including field instructors to understand relation between school education and computer, generalize and analyze basic data required to acquire basic knowledge to help utilizing the computer for education and seek for understanding. This study intented to present a method to activate computer education focused on utilization education at the elementary education stage. Accordingly, those computer educations on middle/high schools and universities and through social educations have been excluded from the object of the study. In order to conduct fruitful computer education, several supporting systems should be equipped completely such as teachers, facilities, software, etc. Especially, practical experience of using computer is the most important element in the computer education, every school should be equipped with computers to prepare for its generalization. Roles of the teachers have also very important influence on it. Research and development of education software require expert knowledge and enormous time and effort and the developed software should be followed by the systematic evaluation on its quality.

우회적인 공격에 대한 실제 IP 역추적 실시와 포렌식 자료 생성
윤병선(Byung-Sun Youn),김동준(Dong-Jhoon Kim),양해술(Hae-Sool Yang) 한국컴퓨터정보학회 2008 韓國컴퓨터情報學會論文誌 Vol.13 No.1
본 논문에서는 자신의 Real IP 주소의 노출을 피하기 위하여 우회적인 공격을 하는 침입자를 대상으로 하여 IP 역추적을 실시한다. Real IP 역추적을 위하여 IP 역추적 서버와 에이전트 모듈을 설계하고 실험실 인터넷 네트워크 시스템에 설치한다. 우회 접속자의 공격 탐지 및 추적 범위를 설정하고, 실제 공격을 하여, 일반적인 IP 접속 자료와 침입탐지 후에 치명적인 공격으로 차단된 Real IP 자료를 생성하여 DB에 저장한다. 공격자의 Real IP는 Whois 서비스로 실체를 확인하고, 이를 법정의 증거자료로 삼기위한 무결성과 신뢰성을 확보한 Forensic 자료를 생성한다. 본 논문 연구를 통하여 유비쿼터스 정보화 사회의 역기능인 사이버 범죄의 예방효과와 효과적인 Real IP 역추적 시스템을 제시하고, 법의 처벌에 대한 Forensic 자료 생성 기준을 확보한다. Execute IP traceback at this paper as target an intruder's attacking that Bypass Attack in order to avoid an exposure of own Real IP address. Design IP traceback server and agent module, and install in Internet network system for Real IP traceback. Set up detection and chase range aggressive loop around connection arbitrariness, and attack in practice, and generate Real IP data cut off by fatal attacks after data and intrusion detection accessed general IP, and store to DB. Generate the Forensic data which Real IP confirms substance by Whois service, and ensured integrity and the reliability that buy to early legal proof data, and was devoted to of an invader. Present the cyber criminal preventive effect that is dysfunction of Ubiquitous Information Society and an effective Real IP traceback system, and ensure a Forensic data generation basis regarding a judge's robe penalty through this paper study.

XML을 이용한 효율적인 통합 무선 컨텐츠 서비스 지원 시스템에 대한 연구
金東俊 배화여자대학 2002 培花論叢 Vol.21 No.-
Techniques on CDMA 2000 1x and IMT-2000 are advancing and wireless services are prevailing from WAP text services on existing mobile phone to up-to-date terminals with various displays so that the corresponding center systems development are required. However, the existing development methodologies such as WML based WAP and HTML & CGI based Web development is not proper to respond effectively for the requests for the development of services for various terminals. Whenever new terminal is developed, the matching web applications should be created. It can increase cost of development and delay the schedule because of the duplicated development of similar functions. Efficient Supporting System for Integrated Wireless Contents Service using XML, which can meet various terminal environments, is suggested in this study.
