  • Nowadays, the user-centric application based web 2.0 has replaced the web 1.0. The users gain and provide information by interactive network applications. As a result, traditional approaches that only extract and analyze users' local document operating behavior and network browsing behavior to build the users' preference profile cannot fully reflect their interests. Therefore this paper proposed a preference analysis and indicating approach based on the users' communication information from MicroBlog, such as reading, forwarding and @ behavior, and using the improved PersonalRank method to analyze the importance of a user to other users in the network and based on the users' communication behavior to update the weight of the items in the user preference. Simulation result shows that our proposed method outperforms the ontology model, TREC model, and the category model in terms of 11SPR value.

  • 21세기에 들어서 인문학계와 과학계가 서로 융합되며 새로운 이론과 모델들이 창출되고 있다. 그 중에서도 여러 제반분야에서 관심을 받는 이론이 체화된(embodied) 인지이론이다. 본 연구는 이때까지의 정보학 이용자 행태에 대한 메타이론을 간략하게 살피고, 그 한계를 짚어 본다. 다음으로 이러한 체화된 인지이론과 더불어 정보행위의 주체인 인간이 속하는 생명체에 관한 엔트로피 개념을 도입해 새로운 시대의 흐름에 맞는 생명 패러다임 정보행태모델을 제시하고자 한다. 검색이라는 개념과 이용자의 행위에 대한 개별적인 접근의 한계를 극복하고 통합적 패러다임으로서의 새로운 정보검색이론의 담론을 기대한다.

  • 소비자의 많은 의사결정은 제품에 대한 감정적 반응에 일어나며, 마케팅에서는 이러한 다듬어지지 않은 반응을 정서(Affect)라고 칭한다. 정서에는 평가(evaluation), 무드(mood), 감정(emotion)과 같은 반응 유형도 있으나, 무의식적인 변화를 의미하는 감성(Sensibility) 또한 이에 포함된다. 선행 연구들에 따르면 기상요소들은 사람들의 이러한 감성에 영향을 미치며, 이는 기상요소들이 소비자들의 의사결정에 영향을 미칠 수 있음을 나타낸다. 본 연구에서는 기상정보와 SNS상의 텍스트마이닝을 통한 위치기반 텍스트 정보를 활용, 기상정보를 통한 감성 예측 모형을 만들어내고, 이러한 감성 모형이 실제 온라인 쇼핑몰 구매자들의 주소 정보와 매칭한 구매자들의 구매 시기 날씨 정보와 결합하여, 기상요소들이 구매자들의 구매 빈도에 미치는 영향을 살펴본다. 본 연구 결과 일 강수량, 합계 일조시간, 평균 지면 온도, 평균 상대습도를 사용한 모형이 온라인 구매 행위 빈도에 유의미한 결과를 나타내었다.

  • In cloud computing infrastructure, current virtual machine trust measurement methods have many shortcomings in dynamism, security and concurrency. In this paper, we present a new method to measure the trust of virtual machine. Firstly, we propose "behavior trace" to describe the state of virtual machine. Behavior trace is a sequence of behaviors. The measurement of behavior trace is conducted on the basis of anticipated trusted behavior, which not only ensures security of the virtual machine during runtime stage but also reduces complexity of the trust measurement. Based on the behavior trace, we present a Dynamic Tree Style Trust Measurement Model (DTSTM). In this model, the measurement of system domain and user domain is separated, which enhances the extensibility, security and concurrency of the measurement. Finally, based on System Call Interceptor (SCI) and Virtual Machine Introspection (VMI) technology, we implement a DTSTM prototype system for virtual machine trust measurement. Experimental results demonstrate that the system can effectively verify the trust of virtual machine and requires a relatively low performance overhead.

  • 본 연구는 인지적, 정서적, 환경적 측면을 포함한 통합적 관점에서 방송콘텐츠 창작자들이 방송기획과정에서 정보를 이용하는 과정을 분석하여 정보활동모형을 개발하였다. 방송콘텐츠 창작자들은 공통된 인지적 프로세스 단계를 통해 정보의 교환과 통합을 이루며, 대중과의 정서적 공감을 위하여 최근의 뉴스와 인간 및 일상생활전반에 대한 정보를 끊임없이 탐색한다. 또한 정보의 시대성과 시의성, 방송사회내의 규범과 문화적 맥락도 중요한 정보원이며 정보에 대한 판단은 주관적이며 경험적으로 이루어지고 있음을 밝혀내었다.

  • Purpose As job market squeezes and more institutions have been requiring NCS(National Competency Standards) based recruitments, the importance of NCS has been growing. Among the 10 domains of NCS, the most relevant one with MIS(Management Information Systems) field is 'information ability', which is becoming more important with the advent of the fourth industrial revolution era. The purpose of this study is to investigate the effect of college students' information ability on their career preparation behavior. Design/methodology/approach In this study, we set up a process model to comprehend the effect of college students' information ability on career preparation behavior based on social cognitive career theory. For research model testing, 561 questionnaires were used for empirical analysis through structural equations modeling. Findings Empirical analysis showed that information ability positively influenced college students' career preparation behaviors for employment. In addition, this study presented a process model explaining the effect of information capability on career preparation behavior. In order to strengthen the information ability of college students, not only university-level efforts, but also MIS discipline efforts should be accompanied. Other academic and practical implications are discussed.

  • Though much attention has been paid to offer various multimedia services by many online service providers, the study on consumer behavior of online information service users are yet to be further explored in various aspects. This study develops a mathematical model for analyzing online consumer's usage patterns, contrasted to the existing media selection theory and flow concept about usage behavior of information services. We demonstrated using some case examples that online information consumption can be viewed not only as a cognitive behavior interacting with online media, but also as an economically rational behavior depending on consumer's perceived cost and time spending. The results obtained in this paper will surely serve as a theoretical foundation for justifying the consumer's behavior and WTP (willingness to pay) for various online contents consumption empirically.

  • Purpose The purpose of this study is to empirically identify the risky behavior of mobile device users using the Internet of Things on a situational perspective. Design/methodology/approach This study made a design of the research model based on model of the determinants of risk behavior. Data were collected through a survey including hypothetical scenario. SmartPLS 2.0 was used for the structural model analysis and t-test was conducted to compare the between normal and situational behavior. Findings The results were as follows. First, the central roles of risk propriety and risk perception were verified empirically. Second, we identified the role of locus of control as a new factor of impact on risky behavior. Third, mobile risk propensity has been shown to increase risk perception. Fouth, it has been shown that risk perception does not directly affect risky behavior and reduce the relationship between mobile risk propensity and risk behavior. According to the empirical analysis result, Determinants of risk behavior for mobile users were identified based on a theoretical framework. And it raised the need to pay attention to the impact of locus of control on risk behavior in the IS security field. It provided direction to the approach to risky behavior of mobile device users. In addition, this study confirmed that there was a possibility of taking risky behavior in the actual decision-making.

  • The brain of the human is the best model for the artificial intelligence and is studied by many natural, medical scientists and engineers. In the engineering department, the brain model becomes a main subject in the area of development of a system that can represent and think like human. In this paper, we approach and define the function of the brain biologically and especially, make a model for the function of cerebral cortex, known as a part that performs behavior inference and decision for sensitive information from the thalamus. Therefore, we try to make a model for the transfer process of the brain. The brain takes the sensory information from sensory organ, proceeds behavior inference and decision and finally, commands behavior to the motor nerves. We use the modular neural network in this model. finally, we would like to design the intelligent system that can sense, recognize, think and decide like the brain by learning the information process in the brain with the modular neural network.
