Recently, since the number of internet users is increasing rapidly and, by using the public hacking tools, general network users can intrude computer systems easily, the hacking problem is getting more serious. In order to prevent the intrusion, it is needed to detect the sign in advance of intrusion in a positive prevention by detecting the various foms of hackers' intrusion trials to know the vulnerability of systems. The existing network-based anomaly detection algorithms that cope with port- scanning and the network vulnerability scans have some weakness in intrusion detection. they can not detect slow scans and coordinated scans. therefore, the new concept of algorithm is needed to detect effectively the various forms of abnormal accesses for intrusion regardless of the intrusion methods. In this paper, SPAD(Session Pattern Anomaly Detector) is presented, which detects the abnormal service patterns by comparing them with the ordinary normal service patterns.

The rapid development of information communication technology(ICT) is born opportunities of business venturing and many items of start-up. On the smart media era, there are a lot of location based services. Thus we researched to find which factors impact location based constructs on smartphone environment in this study. We have conducted a preference analysis of the influencing factors for location based constructs for our study. In first steps, based constructs that were already known by empirical studies were categorized information, entertainment, safe&emergency, navigation&tracking and advertising&commerce. In second steps, the preference relationship among the categorized constructs were analyzed using AHP(analytic hierarchy process) technique. Participants of this study were 106 students H university in Daejeon-city during 2014. 10. 11 to 2014. 10. 25. The result of the analysis might be summarized that the chatting(0.170) has the highest preference among the above constructs. Based on these findings, several theoretical and practical implications were suggested and discussed.

Context-Aware is a one of the important researches in ubiquitous computing for providing optimal service to users by acquiring user's intentions and environmental information. Diverse researches are focused on the users and its environment facts for Context-Aware base and introduce a sensing based middleware which engages sever/sensor that operates identifier information to provide services. Context-Aware service which is limited by users and environment facts has the problem of overlapping sensing, unnecessary searching and anonymity of users. Also Server-Centric Context-Aware system requires very high cost to manage and operate the services. On this paper, We introduce Autogenous Context service model to simplify the Context-Aware process and design the middleware which performs decentralize management for Context-Aware information of user's portable devices to minimize problems which is occurred during the management and operation of existing Context-Aware system.

산업안전보건법에 따르면 결함수 분석기법(Fault Tree Analysis, FTA)은 주로, 설계 또는 운전단계에 있는 공정 위험성 평가 시 사고의 발생빈도와 예상사고 시나리오를 추정하는데 적용되어왔다. 따라서 일반적인 결함수 분석에서 정상 사상은 시스템 자체의 사용불능을 야기하는 가장 큰 원인을 의미한다. 그러나 상수도의 유지관리를 위해 FTA를 적용한 경우 정상 사상은 일반적인 FTA에서의 정상 사상과는 다르게 정의되어야 한다. 즉, 용수공급의 경우 관망 전체에 영향을 미치는 정상 사상이란 수원지의 오염이나, 수원지에서 직접적으로 나오는 관로에 문제가 생겼다거나 하는 사건을 의미하므로, 이러한 방식의 정상 사건 정의는 관망의 관로 및 절점에서 발생되는 문제를 분석하기 어렵게 만든다. 따라서 본 연구에서는 관망의 특정 지점에 용수공급이 원활하게 되지 않는 경우를 FTA의 정상사상으로 정의하였다. 또한, 개개의 관로 노후도 평가 점수와 FTA를 이용하여 관망의 특정 절점에 용수를 공급하기 위한 관로들의 노후도 평가 평균 점수를 산출하였다. 개발한 프로그램에서는 평균 노후도 평가 점수를 산출하기 위해서, 특정 절점 값을 입력 받고 각 파이프와 그로 인해 생기는 고립구간(세그먼트 + 비의도적 고립구간) 에 포함되는 절점들의 관계를 나타낸 자료를 이용하여 파이프에 문제가 생길 시 단수되는 절점을 역으로 검색해서 각 파이프의 노후도 평가 점수를 산술평균 하였다. 본 연구에서는 특정지점에 용수 공급이 원활하지 못 한 정상사상에 대하여 관로의 수리 또는 교체를 해야 하는 구간을 찾아 노후도 평가 점수를 산정하는 것이 목표이다. 이를 위해 특정 절점에 용수를 공급하기 위하여 지나가는 관로들에 대해서 평균 점수를 구함으로써, 절점에 용수가 원활히 공급 될 가능성을 산정하여 FTA와 관로 노후도 평가 점수를 이용하고 특정 절점에 용수를 공급하기 위하여 지나가는 관로들에 대해서 평균 점수를 산정하였다. 절점에서 용수를 공급하는 중요도에 따라 절점으로 이어지는 관로의 평균 노후도를 일정 점수 이하로 유지시키는 방법을 이용함으로써 관로의 유지관리 필요성에 대해 지표로써 사용할 수 있다.

As the importance of human-computer interaction (Human Computer Interface) technology grows and research on HCI is progressing, it is inferred about the research emotion inference or the computer reaction according to the user's intention, not the computer reaction by the standard input of the user. Stress is an unavoidable result of modern human civilization, and it is a complex phenomenon, and depending on whether or not there is control, human activity ability can be seriously changed. In this paper, we propose an intelligent emotional recommendation system using music as a way to relieve stress after measuring heart rate variability (HRV) and acceleration photoplethymogram (APG) increased through stress as part of human-computer interaction. The differential evolution algorithm was used to extract reliable data by acquiring and recognizing the user's biometric information, that is, the stress index, and emotional inference was made through the semantic web based on the obtained stress index step by step. In addition, by searching and recommending a music list that matches the stress index and changes in emotion, an emotional recommendation system suitable for the user's biometric information was implemented as an application.
