  • COVID-19 vaccines have been developed worldwide in order to prevent the spread of coronavirus infection-19, but some people tend to refuse to be vaccinated against COVID-19. Therefore, we will investigate how people's understanding of COVID-19 vaccines affects their attitude to accept COVID-19 vaccination information. Therefore, the purpose of this study is to examine the determinants that affect the acceptability of COVID-19 vaccine through the informational characteristics of COVID-19 vaccine and the individual health belief theory. This study conducted an offline survey of 215 adult men and women living in Seoul and Gyeonggi-do Province during the period from September 1 to September 10, 2022, and we have conducted a final analysis using a total of 212 questionnaires. The results of our study were as follows. First, among the information characteristics of COVID-19 vaccine, it was confirmed that the amount of information had a significant positive effect on susceptibility, severity, and barriers in health belief theory, respectively. Second, among the information characteristics of COVID-19 vaccine, it was found that the quality of information had a significant positive effect on the susceptibility in health belief theory. Third, susceptibility and barriers in the health belief theory significantly had a positive effect on voluntary attitude and involuntary attitude in acceptance attitude, respectively. And finally, it was found that the severity of the health belief theory had a positive effect on the involuntary attitude in acceptance attitude. The results of this study suggest that policy efforts are needed to make accurate information about COVID-19 vaccine known to the people.

  • The purpose of this research is to understand users' information protection behavior on personal information security from health psychology theory perspectives. Empirical results indicate that users' information protection behavior on personal information is predicted by perceived threat and perceived responsiveness. Perceived threat is determined by perceived susceptibility and perceived severity. Perceived responsiveness is determined by response efficacy and self-efficacy, but response cost is not significant. These findings provide an enriched understanding about users' information protection behavior on personal information security.

  • Information theory is one field of the applied mathematics quantitating the data in order to store data as many as in the medium or communicate through channel. it was released on the Shannon's paper, in 1948. With basis on this paper, It has been achieved dramatically development for communication, signal processing, and date procedure and transmission in the network In this paper, the basic concept of information theory is described through dealing with contents about meaning of information, entropy, and channel capacity. It is also handled how information theory is applied to the fields of sensor network, relay channel, MIMO system, and others.

  • The purpose of this study is to promote understanding of the book selection theory by researching dialectically of its development process centering on the BSTv(value theory) and BSTd(demand theory). The results of this study are summarized as follows 1. In the period of enlightenment and education, the book selection theory of public libraries was the thesis state of BSTv(d). 2. Antithesis state of BSTv(d), that is, BSTd was raised to real central theory of book selection in the early 20th century. 3. In the 1930-40's, BSTv and BSTd were transformed into balance state or coexistence relations(BSTb $[v(d){\cdot}d(v)$]. 4. After World War II, BSTn(library needs theory) and BSTo(library objective theory) were evoked, and opposed to the existing selection theories. Now, they are developing into BSTbl$[n(d)\cdot\;o(v)\;or\;n(d){\cdot}v(o)]$.

  • 일반적으로 정보유출사건은 외부 해커에 의해 발생된다고 생각되지만 내부자에 의한 직간접적인 정보유출사건이 더 많고 전체 유출비중의 과반 수 이상을 차지하기 때문에 내부자 유출에 대한 대비가 필요하다. 본 연구에서는 일반 억제 이론과 합리적 선택 이론을 기반으로 교통심리학 분야에서 연구되었던 행동결정요인인 위험감수성과 상황불안을 통합해 연구모델을 구성하고 설문조사를 통해 실증분석 하였다. 분석 결과, 위험감수성이 지각된 처벌의 심각성 및 확실성에 미치는 영향은 통계적으로 유의미하지 않았으나, 지각된 이익, 상황불안, 지각된 처벌의 심각성 및 확실성은 정보유출의도에 영향을 주는 것으로 확인되었다.

  • To establish an effective security strategy, business enterprises need a security benchmarking tool. The strategy helps to lessen an impact and a damage in any threat. This study analyses many aspects of information security management and suggests a way to deal with security investments by considering important factors that affect security manager's decision. To address the different threats resulting from a major cause of accidents inside an enterprise, we investigate an approach that followed ISO17799. We unfold a criminology theory that has designated many measures against the threat as suggested by General Deterrence Theory. The study proposes a coherent model of the theory to improve the security measures especially in handling and protecting company assets and human lives as well.

  • As an increasing number of people gained access to social network services (SNS), organizations started to use SNS as a channel for marketing and promotional purposes. The online advertising market has significant growth potential. Brand engagement is a key motive for online advertising, but how SNS users engage with brands, particularly in terms of the promotion of organizations, is poorly understood. This study uses customer value theory to examine brand engagement of users in terms of promoting companies in the context of Korean SNS marketing. This study identifies the antecedents of brand engagement based on customer value theory. Our findings show the significance of three factors of SNS marketing, namely, price discount, relationship support, and convenience, on brand engagement. We further show the consequences of brand engagement, namely, purchase decisions and word-of-mouth activities. These findings help advance customer value theory and offer practical insights into the use of information systems and marketing in the context of SNS.

  • 조직은 정보 보안 기술에 대한 지속적인 투자를 통하여 다른 기업들보다 정보자원에 대한 경쟁력을 높이고 있다. 그러나 정보보안 기술 및 정책을 실행에 옮기는 조직원의 정보보안에 대한 관심이 상대적으로 저조하다. 본 연구는 정보보안 분야에 계획된 행동이론, 공정성이론, 그리고 동기이론을 적용하여 조직원의 정보보안 준수의도를 높이기 위한 메커니즘을 찾는다. 연구대상은 정보보안 정책을 도입한 조직의 조직원들이며, 서베이를 통하여 유효샘플 383개를 수집하였다. 연구가설 검증은 구조방정식 모델링을 실시하였다. 결과는 조직공정성, 외재적 동기(제재), 내재적 동기(조직일체화)가 계획된 행동이론의 세부 요인들에 영향을 주고 개인의 정보보안준수의도에 영향을 주는 것으로 나타났다. 분석 결과는 조직의 보안정책에 대한 조직원들의 준수의도 향상을 위한 전략적 접근 방향을 제시한다.

  • This paper proposes a quantitative approach to modeling the information processing of NPP operators. The aim of this work is to derive the amount of the information processed during a certain control task. The focus will be on i) developing a model for information processing of NPP operators and ii) quantifying the model. To resolve the problems of the previous approaches based on the information theory, i.e. the problems of single channel approaches, we primarily develop the information processing model having multiple stages, which contains information flows. Then the uncertainty of the information is quantified using the Conant’s model, 3 kind of information theory.

  • 본 연구의 목적은 사회적 관점에서 정보행위를 분석하는 이론 중의 하나인 정보세계이론에 대한 이해와 활용도를 높이는 데 있다. 정보세계이론에 대한 이해를 위해 해당 이론을 적용한 박사학위논문을 수집 분석하여 이론의 적용과 방법론에 대해 분석함으로써 이론적 함의를 제시했다. 정보세계이론은 2008년 Burnett과 Jaeger에 의해 제시된 이후 14편의 박사학위논문에서 사용되었다. 이론을 구성하는 개념은 사회적 유형, 사회적 규범, 정보가치, 정보행위, 경계로 이들 개념은 상호배타적으로 정보세계를 구성하기보다는 개념 간의 상호작용을 통해 지속적으로 영향을 미치면서 행위를 생산하고 통제한다. 정보세계이론을 적용한 연구는 양적 연구보다는 질적 연구를 기반으로 이루어지며 이론을 구성하는 주요 개념들에 대한 분석과 그 상호작용을 분석하기 위해 인터뷰와 내용분석이 주로 사용되는 것으로 나타났다. 본 연구를 통해 정보세계이론이 한국 문헌정보학 연구에 활용됨으로써 정보행위 분석의 지평을 넓히는데 기여할 것으로 기대된다.
