고가용 E-Business모델을 위해 구축된 나중 웹 클러스터 모델은 구조적 특성상 내부 시스템 노드들이 노출되어 있으며, 불법적인 3자에 의한 고의적인 방해와 공격으로 정상적인 작업수행이 불가능할 가능성을 지고 있다. 따라서 구성된 시스템 노드들을 보호하고 불법적인 사용자로부터의 정보유출과 부당한 서비스 요구를 효과적으로 대응할 수 있는 보안 시스템이 필요하나 제안한 분산 침입 탐지 시스템은 불법적인 침입을 탐지하기 위하여 일차적으로 Detection Agent를 이용한 작업요구 패킷의 검사를 수행하려, 이후 작업이 진행되었을 때 Monitoring Agent를 동하여 작업과정을 관찰하며 허용되지 않는 자원의 접근 및 요구가 발생하였을 때, 다른 시스템 노트와의 긴밀한 협조작업을 동해 침입여부를 판단한다.

With the rapid growth of the Internet, various web-based businesses are creating a new environment in an imaginary space. However, this expanding Internet and user increase cause an overflow of transmission and numerous subordinate problems. To solve these problems, a parallel cluster system is produced using different methods. This thesis recommends a multi0distribution cluster group. It constructs a MPP dynamic distribution sub-cluster group using numerous low-priced and low-speed systems. This constructed sub-cluster group is then connected with a singular virtual IP to finally serve the needs of clients (users). This multi-distribution cluster group consists of an upper structure based on LVS and a dynamic serve cluster group centered around an SC-server. It conducts the workloads required from users in a parallel process. In addition to the web service, this multi-distribution cluster group can efficiently be utilized for the calculations which require database controls and a great number of parallel calculations as well as additional controls with result from the congestion of service.

The limits of current DN(Defense networks), private and closed network, become to reality; for Example, high expense of construction and maintenance of networks, restriction of new subscribers on DN. Therefore, a network using web environment that reflect fast development of If and IS(Information Security) technology is demanded for MND. Meeting the requirement of reliable IS system and extension and improvement of DN using common network, we can reduce the expense to extend, maintain, repair DN, form the environment that makes military business cooperate better with civil company and government agency, advance implementing Defense computing and networking service for field small size units that was a exception of Defense digitalization. But it is essential to construct DN based on common network that there are security requisites; confidentiality, integrity, availability, efficiency, log, backup, restoration, that have to be realized at demanding level for IS. This thesis suggested four measurements; replacement DN with common network to resolve the requirements of building new network and improvement of performance for private DN, linkage with common network for new requirement, distribution of traffic using common network, configuration of DN using Internet and Proposed a refinement of IS management organization to treat security threat of common network flexibly, and LAN IS standard model of DN based on the web environment.

This study presents a web log analysis model for e-CRM, which combines the on-line customer's purchasing pattern data and transaction data between companies in B2B environment of make-to-order company. With this study, the customer evaluation and the customer subdivision are available. We can forecast the estimate demands with periodical products sales records. Also, the purchasing rate per each product, the purchasing intention rate, and the purchasing rate per companies can be used as the basic data for the strategy for receiving the orders in future. These measures are used to evaluate the business strategy, the quality ability on products, the customer's demands, the benefits of customer and the customer's loyalty. And it is used to evaluate the customer's purchasing patterns, the response analysis, the customer's secession rate, the earning rate, and the customer's needs. With this, we can satisfy various customers' demands, therefore, we can multiply the company's benefits. And we presents case of the 'H' company, which has the make-to-order manufacture environment, in order to verify the effect of the proposal system.

웹 2.0이 사회적인 이슈로 대두되면서 인터넷 기반의 모든 시스템과 서비스 환경은 새로운 전기를 맞고 있다. 기존 웹 서비스는 서비스 제공자가 제공하는 정보와 데이터를 일방적으로 사용자가 이용하거나 또는 가공하여 처리하는 형태를 취하였으나, 웹 2.0 환경에서는 서비스 제공자가 제공하는 플랫폼과 정보를 이용하여 사용자가 자신만의 경험과 노하우를 이용해 또 다른 새로운 정보를 창출할 수 있다. 즉 사용자가 웹 2.0의 환경에서는 서비스 제공자가 만들어 놓은 플랫폼에서 새로운 콘텐츠 제공자의 역할을 하면서 디지털 콘텐츠 시장은 새로운 패러다임을 쏟아내고 있다. 그 중에서 가장 눈에 띄는 서비스는 UCC(User Created Contents)로 사용자의 적극적인 참여와 흥미를 유발하고 있다. 또한 SNS(Social Network Service)와 같은 가상의 공간에서 또 다른 자아를 실현 해 나가는 형태의 서비스가 주류를 이루고 있으며 세컨드라이프닷컴 등이 대표적인 사이트로 자리잡아가고 있다. 본고에서는 웹 2.0 환경을 정의하고, 새로운 환경에서 나타난 다양한 서비스들을 UCC, SNS, VR(Virtual Reality) 환경에서의 콘텐츠 등의 형태로 분류하여 정리하였다. 또한 새로운 서비스의 미비점을 분석하여 미래에 지향해야 할 방향을 제시하고 개선점을 도출함으로써 WEB2.0 환경에서 등장하게 될 신규 서비스 성장 모델의 방향을 전망하였다.

This study proposes the O P E N Triad framework as a future set of tools and perspectives for individual members and institutes to further their professional and academic potential as well as prospect and vitalize the future of the Korean Clothing and Textiles discipline through a global perspective. The millennial generation desires On-demand, Personal, Engaging, and Networked (O P E N) experiences effecting cultural change for creative and influential interaction in transactions, communication, and education. O P E N Individuals offers a WebSphere model as a holistic learning system that has a synergizing value of education across academic courses, industries, and cultures. Through a digitalized and virtualized class, it complements relevant technologies already familiar to the student population. By employing environmental scanning approaches, the most influential and viable future global issues related to the clothing and textiles discipline are identified and dialogued within O P E N Institutes. For future clothing and textiles institutes, this scanning allows them to be open to new ideas, to focus on inter-engagements, to collaborate among individuals, to associate as a part of web of people, organizations, and ideas, to personalize an institutes curricula, and to dialogue generative knowledge. O P E N Industries reveals three dominant future issues that cross academia and industry, sustainability, supply chain management, and social networking. In-depth interviews with U.S. industry experts identified interdependent gaps in global consumer experience practices and suggested the following gaps as future research areas: a standardized business model to the entrepreneurial model, strategic management to a sustainable competitive advantage, standardized to differentiated products, services and operations, market segmentation to global consumer clusters, business-driven marketplaces to consumer-engaged marketspaces, and excellent services to optimal experience. This O P E N Triad framework empowers millennial students, universities, and industries to anticipate and prepare for a radically changing world.

Analysis of a bipartite (two-mode) network is a significant research area to understand the formation of social communities, economic systems, drug side effect topology, etc. in complex information systems. Most of the previous works talk about a projection-based model or latent feature model, which predicts the link based on singular similarity. The projection-based models suffer from the loss of structural information in the projected network and the latent feature is hardly present. This work proposes a novel method for link prediction in the bipartite network based on an ensemble of composite similarities, overcoming the issues of model-based and latent feature models. The proposed method analyzes the structure, neighborhood nodes as well as latent attributes between the nodes to predict the link in the network. To illustrate the proposed method, experiments are performed with five real-world data sets and compared with various state-of-art link prediction methods and it is inferred that this method outperforms with ~3% to ~9% higher using area under the precision-recall curve (AUC-PR) measure. This work holds great significance in the study of biological networks, e-commerce networks, complex web-based systems, networks of drug binding, enzyme protein, and other related networks in understanding the formation of such complex networks. Further, this study helps in link prediction and its usability for different purposes ranging from building intelligent systems to providing services in big data and web-based systems.
