한 해에도 수많은 해킹 사고가 발생하고 있고, 이 중에서 웹 해킹이 차지하는 비율은 급격하게 증가하고 있다. 또한 최근의 해킹 동향을 분석해 보았을 때 웹 해킹의 비율은 더욱 증가할 것이라고 예상된다. HTTP 프로토콜을 이용한 공격의 특성 상 정상행위와 비정상 행위의 구분이 어렵다. 따라서 웹 서비스에 특화된 침입탐지 시스템이 요구된다. 또한 웹 사이트 관리자는 빠른 탐지와 대응을 위해 이상 행위에 대한 신속하고 정확한 인식을 필요로 한다. 본 논문에서는 이러한 필요성을 기반으로 Location-based Visualization Tool을 제안한다. 웹 사용 현황 및 이상행위에 대해 시각적인 정보를 제공하기 위해 웹 서버의 access log를 분석하여 이상 행위를 탐지하였고, IP정보를 기반으로 지역 정보의 시각화를 구현하였다.

During the last decade, increasing use of technology that facilitates information access has changed academic library services. The emergence of information commons is one of the key changes. Most previous studies on information commons have focused on its conception and role. Whereas, considering information commons as a spatial service, this study aims to examine the influence of information commons on user traffic patterns within the library and perception of the library. As the information commons grew into main library service space and facility, it is necessary to explore what influences information commons have on the behavior and recognition of users. Two methods were used. First, observation method was used to record traffic pattern and user behavior. Second, twenty undergraduates and twelve graduates were interviewed regarding the use and recognition of the information commons and the library. The results of the study show that the traffic patterns were different between undergraduate students and graduate students; the location and structure of facilities influences their movement and behaviors; and the recognition of information commons tends to affect the perception of the entire library. The findings may help librarians improve and plan for library spaces to meet user demands.

Internet companies that utilize social network have increased in number. The introduction of diverse social media services facilitated innovative changes in e-business. Social network service (SNS), which is a domain of social media, is a web-based service designed to strengthen human relations in the Internet and build new social relations. The remarkable growth of social network services and the profit generation and perception of this service are the new growth engines of this digital age. Given this development, many global IT companies views SNS as the most powerful form of social media. Thus, they invest efforts to develop business models using SNS.2) This study verifies the impact of privacy exposure in SNS as a result of privacy invasion. This study examines the purpose of using the SNS and user's awareness of the significance of personal information, which are key factors that affect self-disclosure of personal information. This study utilizes theory of reasoned action (TRA) to provide a theoretical platform that describes the specific behavior and emotional response of individuals. This study presents a research model that considers negative attitude (negatude). In this model, self-disclosure in SNS is considered a TRA. TRA is a subjective norm, a behavioral intention, and a key variable of exposure behavior. A survey was conducted on college students at Y university in Seoul to empirically verify the research model. The students have experiences in using SNS. A total of 198 samples were collected. Path analysis was applied to analyze the relations of factors. The results of path analysis show the statistically insignificant impact of privacy invasion on negatude, subjective norm, behavioral intention, and exposure behavior. The impact of unrecognized privacy invasion was also considered insignificant. The impacts of intention to use SNS on negatude, subjective norm, behavioral intention, and exposure behavior was significant. A significant impact was also found for the significance of personal information on subjective norm, behavioral intention, and exposure behavior, whereas the impact on negatude was insignificant. The impact of subjective norm on behavioral intention was significant. Lastly, the impact of behavioral intention on exposure behavior was insignificant. These findings are significant because the study examined the process of self-disclosure by integrating psychological and social factors based on theoretical discussion.

The goal of this study is to identify factors that influence on the persistent information security compliance intention of employees. Antecedents suggested in research model are security awareness training and perceived effectiveness of information security policy. Research results show that security awareness training has a positive effect on persistent information security compliance intention as well as effectiveness of information security policy. While policy breadth, which is one of the effectiveness of information security policy, influences on persistent information security compliance attitude and intention, policy brevity does not effect on persistent information security compliance intention. Conclusions and implications are discussed.

1. The traditional view of nature in oriental medicine originated with a horizontal relation between nature and human. But the Sasang Constitution Medicine is based on the thought that ethical value is due to nature and at the same time nature could be transformed by ethical inclination. 2. The Sasang Constitution Medicine is not only a clinical medicine, but also a nature-philosophical system which implies the korean general view of nature. 3. We must examine a thought critically, four seperated physical structure were indeed deterministic. A deterministic understanding is false, because it is based on the recipiency of western philosophical ontology without reflection. 4. Korean view of nature is not kept in the fixed structure, and then can be opened and transformed by personal doings (practical acts). It is important that Sasang medicine is the pathology centering on man which is embodiment of ethical judgements.

Social Network Service(SNS) users are increasing globally. Within that trend, 'SNS attacking' victims are increasing in social network service space like KakaoStory, facebook, or Instargram as people damage others' personality or reputation. In this paper is to investigate and analyze awareness of negative behavior attributed to disinhibition effect with undergraduates who are the group of people using social network service the most diversely in smart environment and devise preventive measures to reduce social network service attacking victims and attackers. In social network service space, undergraduates are hardly aware of other people's personality, defamation, or invasion of privacy, and the level of guilt they feel towards social network service attacking is seriously low. To solve this problem, this study suggests preventive measures so that they can be equipped with awareness and regulations right for this social network service age and can prevent negative behavior resulted from disinhibition effect.

The mirror neuron regions which are distributed in cortical area handled a functionality of intention recognition on the basis of imitative learning of an observed action which is acquired from visual-information of a goal-directed action. In this paper an automated intention recognition system is proposed by applying computational model of mirror neuron system to the human-robot interaction system. The computational model of mirror neuron system is designed by using dynamic neural networks which have model input which includes sequential feature vector set from the behaviors from the target object and actor and produce results as a form of motor data which can be used to perform the corresponding intentional action through the imitative learning and estimation procedures of the proposed computational model. The intention recognition framework is designed by a system which has a model input from KINECT sensor and has a model output by calculating the corresponding motor data within a virtual robot simulation environment on the basis of intention-related scenario with the limited experimental space and specified target object.

Main researching issue in affective computing is to give a machine the ability to recognize the emotion of a person and to react it properly. Efforts in that direction have mainly focused on facial and oral cues to get emotions. Postures have been recently considered as well. This paper aims to discriminate emotions posture by identifying and measuring the saliency of posture features that play a role in affective expression. To do so, affective postures from human subjects are first collected using a motion capture system, then emotional features in posture are described with spatial ones. Through standard statistical techniques, we verified that there is a statistically significant correlation between the emotion intended by the acting subjects, and the emotion perceived by the observers. Discriminant Analysis are used to build affective posture predictive models and to measure the saliency of the proposed set of posture features in discriminating between 6 basic emotional states. The evaluation of proposed features and models are performed using a correlation between actor-observer's postures set. Quantitative experimental results show that proposed set of features discriminates well between emotions, and also that built predictive models perform well.

The significant changes of convergence study in the 21st century is the shift from theoretical-based instruction to computer-based instruction. This study investigated the student's cognitive engagement in TPB(Theory of Planned Behavior) of accounting information classes in the Digital Convergence Era. Hypothesis test was conducted from 99 accounting information learners from four year course university in the Gyeonggi-do. A questionnaire was given and analyzed. The results showed. First, the TPB variables han a positive effect on intrinsic curiosity of students. Second, the subjective norm of TPB variables could develop student's enjoyment. Subject norm could have a positive effect on enjoyment. The results of this study may contribute to propose desirable ways of improving the psychological states in the relationship between TPB and cognitive engagement. In the future, variables of cognitive engagement will be compliment to analyze.
