네트웍 기반의 컴퓨터 보안이 컴퓨터 보안분야의 중요한 문제점으로 인식이 된 이래 네트웍 기반의 침입탐지 방법 중 클러스터링(Clustering)을 이용한 비정상 탐지기법(Anomaly detection)을 사용하는 시도들이 있었다. 네트웍 데이터 같은 대량의 데이터의 처리에 클러스터링을 통한 방법이 효과적인 결과를 나타내었음이 다수의 논문에서 제기되어왔으나 이 모델에서의 클러스터링 방법은 네트웍 정보로부터 추출한 정보들을 정상적인 클러스터들과 그렇지 않은 클러스터들 크게 두 집단으로 나누는 방법을 택했었는데 침입탐지율에서 만족할만한 결과를 얻지 못했었다. 본 논문에서 제안하고자 하는 모델에서는 이를 좀 더 세분화하여 네트웍 서비스(Network service)별로 정상적인 클러스터들과 그렇지 않은 클러스터들을 가지게되는 방법을 적용하여 기존 모델에서의 침입탐지율 결과의 개선을 도모해 보고자한다.

많은 기업들이 e-Business를 적극 추진하고 있으나, 기대한 만큼의 경영성과를 올리고 있는 기업은 거의 없는 실정이며, 더 나아가 e-Business의 회의론까지 대두되고 있는 실정이다. 그럼에도 불구하고 e-Business는 Product & Service Leadership, Operational Excellence, Customer Intimacy 확보 차원에서 지속적으로 성장할 것으로 예상된다. 따라서 Off-line 기업의 IT 설비투자 확대, Off-line 기업과 온라인 기업간의 적절한 조화, 기업간 협력 활성화, 닷컴 기업의 경쟁력 확보 등이 갖춰지면 e-business는 향후 우리에게 새로운 도전과 기회를 제공할 것이다.

The interest in wine has been increasing because of raised standard of living, increased leisure time, raised interest in health. Therefore, a few wine related tourism product has introduced to public including wine train to Young-dong region and overseas wine tour package. This study focused on motivation to visit overseas wine tour package in order to segment target wine tourism countries. As a result, three different markets were segmented and they showed different characteristics with regard to demographics, tourism behavior, and preferred wine tourism countries.

In the contemporary society that changes radically, the problems of Juvenile Delinquency shows a tendency to become out-rageous. Organized, intellectual and lower-aged qualitatively together with its qualitative increase to the extent that it may exceed adult crimes, and it is the circumstances that it emerges as an important social problem. Juvenile Delinqurncy is developing into one of the most pressing and critical issues. But, there is no explicit maesure in any country. Above all, Juvenile Delinqurnce is resultd from various factor. For example, personality, family relation, social and environmental problem.

Innovation Policy has evolved to solve social problems through technological innovation. Industrial innovation policy promotes technological innovation so that it consolidates industrial competitiveness and aims at economic growth; however, societal innovation policy promotes technological innovation in the social service domain to improve the quality of life and strengthen sustainability. A different policy regime is required because the objectives and directions of societal innovation policy are different from those of industrial innovation policy. This report consolidates the concepts and characteristics of societal innovation policy that suggest policy options.

The IPTV Standardization work being done by the ITU-T in collaboration with other SDOs and telecommunication companies. Currently IPTV services are provided with no global standards and interoperability. ITU-T leads the process of IPTV standardization. We used the ITU-Ts working documents which were publically available to investigate the direction of IPTV standardization process. Many things including architecture, services, service requirements, codec and error correction mechanisms etc already defined through recommendations. But still there is effort going on to standardize the complete IPTV system.

The common shortest path problem is to find the shortest route between two specified nodes in a transportation network with only one traffic mode. The public transportation network with multiple traffic mode is a more realistic representation of the transportation system in the real world, but it is difficult for the conventional shortest path algorithms to deal with. The genetic algorithm (GA) is applied to solve this problem. The objective function is to minimize the sum of total service time and total transfer time. The individual description, the coding rule and the genetic operators are proposed for this problem.

본 논문은 최근 스마트폰과 Social Network Service(SNS)의 활성화에 따라 이슈화되는 SNS 서비스 기술들과 최신 표준화 동향을 살펴본다. 먼저 SNS 서비스의 근간이 되는 스마트폰과 모바일 OS 기술을 포함하여 위치기반 서비스(LBS) 기술, 증강현실(AR) 기술들과 다양한 웹(WWW) 기술들을 살펴보고 또한 서비스 사업자별로 다양하게 제공되는 소셜 플랫폼 기술을 통하여 현재 SNS 서비스의 기술현황을 파악한 후 보다 향상된 서비스 제공을 위해서 진행 중인 기관 및 단체별 SNS 표준화 동향에 대해서 살펴본다.
