In this thesis, we will break away from the classic DDoS response system for large-scale denial-of-service attacks that develop day by day, and effectively endure intelligent denial-of-service attacks by utilizing artificial intelligence-based technology, one of the core technologies of the 4th revolution. A possible service model development plan was proposed. That is, a method to detect denial of service attacks and minimize damage through machine learning artificial intelligence learning targeting a large amount of data collected from multiple security devices and web servers was proposed. In particular, the development of a model for using artificial intelligence technology is to detect a Western service attack by focusing on the fact that when a service denial attack occurs while repeating a certain traffic change and transmitting data in a stable flow, a different pattern of data flow is shown. Artificial intelligence technology was used. When a denial of service attack occurs, a deviation between the probability-based actual traffic and the predicted value occurs, so it is possible to respond by judging as aggressiveness data. In this paper, a service denial attack detection model was explained by analyzing data based on logs generated from security equipment or servers.

This study sought to find importance factors for the quality of delivery food service, identify the mutual importance of delivery food service quality studied in the preceding study, and derive the order of importance of each factor. To compare the priorities of factors determining the choice of quality of delivery food service, this study used a decision model using the appropriate Analytic Hierarchy Process (AHP) and carried out the process of quantifying the mutual evaluation. This process allows us to view the relative importance and priority of the selection factors. Through a prior study, the main factors of quality of delivery food service were classified and the main people of high importance were selected. According to the results of AHP the quality of deliver service is the main factor for the quality of delivery food service, and the quality of order service and food service is the key factor of the quality of delivery food service, which should take the upper hand in importance. This study results in how important specific factors are by giving relative self-weights to the lower factors, showing that convenience and accuracy always have the first and second place weight priorities in the lower factors, despite differences such as gender age and frequency of making them more convenient and accurate.

This study focused on the role of service robots as employees, and examined how robot services affect customer behavior compared to human employees in service success and failure situations. The three experiments were performed on barista robot, serving robot, and chef robot. The results of this study are as follows. First, in the case of service success, customers showed similar intentions for revisit regardless of employee type. On the other hand, in the case of service failure, the revisit intention was found to be more negative than that of the human employee when the service was received from the robot employee. The reason for this was found to be that customers had lower expectations for the capabilities of service robots compared to humans. Finally, customers perceive that robot services are more stable than human services.

In order to provide the reliable service and contents to telematics service user, any service server must be tested and verified before launching its service in sufficient. In this paper, we proposed a test framework for telematics server. The proposed framework includes conformance test of server, interoperability test between telematics service server and telematics terminal. The framework proposed the concept and test model for two categories of testing.

This paper studies directions for technology information service on Korea material & component industry which is a main course for the deficit of balance of payments in Korea. We have got survey results through e-mail or fax, for the degree of the necessity of the service and the contents for the service. Finally, we will recommend the check point for the service, and for the policy.

In legacy e-learning web service, as deployed contents are changed, web services should be changed together. In addition, it can not coordinate and manage the various e-learning services recently emerged. In this paper, an e-learning platform based on Service-Oriented Architecture (SOA) is proposed to solve these problems. We design and implement an e-learning system based on Service abstraction layer concepts. The implemented system can provide the new e-learning services within short development periods.

Recently there are increasing needs for Internet and various kinds of contents. These traffics for various contents need more amount of data to provide high-quality information and require various QoS depending on the characteristics of contents. However, current Internet service supports BE (Best Effort) service only, therefore IntServ (Integrated Service) scheme and DiffServ (Differentiated Service) scheme are represented to support QoS in IP layer. Moreover, while wireless Internet is getting popular, MAC(Medium Access Control) is also becoming important. This is due to the fact that wireless access, resource allocation and packet scheduling, which are done in another layers before, are performed in MAC layer in many new wireless systems. This paper describes new scheme that provides QoS taking into account the traffic characteristics over Mobile IPv6 network based on IEEE 802.11e EDCF and evaluates the performance through computer simulation.

In korea, the infantile abandonment is increasing recently. In this situation, present study aims to analyze german "confidential birth service"(vertrauliche Geburt) and to find out implications for korean practice. the results of the study are as follows. "confidential birthservice" is centered on pregnancy counseling center. Through this service, pregnant women in crisis are assured of their anonymity and can safely bring baby into the world. After the child is 16 years old, they can learn about personal information of their biological mother. These "confidential birth service" has received positive evaluation in terms of accessibility, sustainability and reliability of services, linkage and cooperation among agencies, quality of counseling and publicity. Implication for Korean pratice include the provision of legal and institutional devices for "confidential birth services", the establishment of implementing agencies, cooperation with related organizations, and the strengthening of the capacity of practitioners, as well as suggestions in the field of counseling and public relations.

The Presidential Archives preserve and manage the president's records and archives, which accounts for the social and governmental operations during the president's term of office. However, search systems and online contents provided by the Presidential Archives are difficult to use. This study proposed an LOD-based archival information service for the comfort of users. The proposed service has a better extension of archival information service contents from President Roh's term. The provision of details is divided into three steps: first step sets up the establishment methods, second step creates ontological design, and third step converts it to RDF and connects to other institutions. Through the process, this study suggests an extension of archival information service in the Presidential Archives.
