A rapid increase was observed among individuals who want to communicate through a Social Networking Service (SNS). The increasing number of SNS users who create and share information resulted in a huge volume of SNS information. This deluge of information decreases the interest of SNS users, thereby prompting them to generate stimulating and exaggerated information to draw attention to themselves. This study aims to examine the effect of SNS users' desire for attention and share their tourism experience. This study utilizes use and gratification theory and investigates the moderating effect of gender. The analysis shows that the desire for attention influences sharing of tourism experience through compliance and identification at the level of SNS commitment. Gender difference was observed between compliance and identification. This study provides theoretical and practical implications based on the results.

ERP supports the automation and integration of business processes of enterprises and records voluminous data about the business activities of enterprises. The academe and business enterprises are focusing on process mining, which improves the performance of business processes and strengthens compliance. However, these studies focused on analysis of the business process of large companies, which adopts foreign ERP, such as SAP ERP or Oracle ERP. In comparison with foreign ERP, domestic ERP lags behind in terms of logging and managing of event data. Therefore, the application of process mining to domestic ERP is a challenging task. The present study aims to analyze domestic ERP based on process mining to overcome this challenge. This study discusses the lessons learned from a case study in a Korean cosmetics manufacturing company. Our results are expected to strengthen the competitiveness of Korean small and medium-sized enterprises that adopt domestic ERP and realize the outcomes of the large investment of the Korean government on the ERP implementation of enterprises.

Technical measures for computer security are essential, but they are not a sufficient condition for security. Therefore, a personal approach to user's security behavior should be developed. Personality, which is a human aspect, is a behavioral characteristic that characterizes each individual and facilitates prediction of how an individual will behave in certain situations. Protection motivation theory has been used extensively in the security research on human behavior. The present study discusses how protection motivation was formed from personality traits. Thus, organizations can refer the result of this study for their HRD and HRM concerns.

Recent recommendation system studies apply various deep learning models to represent user and item interactions better. One of the noteworthy studies is ONCF(Outer product-based Neural Collaborative Filtering) which builds a two-dimensional interaction map via outer product and employs CNN (Convolutional Neural Networks) to learn high-order correlations from the map. However, ONCF has limitations in recommendation performance due to the problems with CNN and the absence of side information. ONCF using CNN has an inductive bias problem that causes poor performances for data with a distribution that does not appear in the training data. This paper proposes to employ a Vision Transformer (ViT) instead of the vanilla CNN used in ONCF. The reason is that ViT showed better results than state-of-the-art CNN in many image classification cases. In addition, we propose a new architecture to reflect side information that ONCF did not consider. Unlike previous studies that reflect side information in a neural network using simple input combination methods, this study uses an independent auxiliary classifier to reflect side information more effectively in the recommender system. ONCF used a single latent vector for user and item, but in this study, a channel is constructed using multiple vectors to enable the model to learn more diverse expressions and to obtain an ensemble effect. The experiments showed our deep learning model improved performance in recommendation compared to ONCF.

Many organizations are implementing Knowledge Management(KM) technologies to promote knowledge sharing. An extensive review of recent articles and journals about such implementations reveals that one of the main barriers to implementation of KM technology is the absence of an organizational culture that supports knowledge sharing. The purpose of this research is to explore the possible relationship between the successful implementation of knowledge management technology and specific organizational culture attributes. The Organizational Culture Profile(OCP) and the Knowledge Management Technology Profile(KMTP) instruments were used to identify and rank the most critical organizational culture attributes and KM technology implementation successes. Data were collected from twenty six US organizations involved in a KM efforts.

Many studies in the field of information security reveal the need to increase awareness. However, although awareness of information security has been raised to a considerable extent, actual security behavior has been shown to fall short of that. Therefore, we wanted to identify the role of psychological factors in making information security decisions by conducting a experimental study. The results show that there are differences in perception of information security risks according to the probabilistic distance and the degree of relative optimism due to social distance. In relation to their relative optimism and intention of information security, they reduced the level of perceived risk compared to those close to them and found that their influence varied according to their probabilistic distance. This study has made valuable attempt in terms of methodology and it is meaningful that the psychological factor is taken into consideration for the information protection behavior, so that the range of relative optimism that actually affects the perception of risk is narrowed. It is expected to contribute to the improvement of information security level of information technology users and protection of information assets by empirically identifying necessity of various approaches to decision making process for information security.

The purpose of this paper is to find out the present status of core courses offered at the Departments of Library and Information Science. For this purpose, the core courses in the curriculum, which were compulsory ones in the 19805, are analyzed. The result shows that there have not been many changes in the core courses offered and that traditional cores of selection, organization, services, administration and information science-related courses are still strongly extant.

본 연구의 목적은 리엔지니어링 작업 구현에 영향을 주고 있는 조직·관리적 요인 들을 실중적으로 연구하는 것이다. 본 연구에는 두 가지 목적이 있다. 첫째, 리엔지니어링 작업의 구현을 성공적으로 이끄는 조직·관리적인 요인들을 조사했다. 본 연구에서 조사되어 질 조직·관리적 요인들을 조직구조, 문화, 최고경영자의 의지, 그리고 리엔지니어링 작업의 구현을 위한 성공요인(success factors) 중에서 어느 요인이 핵심성공요인(key success factors)이지를 나타내고자 한다. 본 연구 결과에서의 성공요인으로는 자율적인 기업 문화, 회고 경영자의 의지, 그리고 관리제도상의 변화인 것으로 나타났고 특히, 자율적인 기업 문 화와 관리제도상의 변화가 핵심 성공요인인 것으로 확인되었다.

최근 들어 초고속 인터넷서비스의 보편화, 무선통신망의 고속화 및 스마트폰 등 새로운 정보통신매체 등이 보급 활성화됨에 따라 인터넷 뱅킹, 사이버 트레이딩 등 전자금융서비스가 보편화되고 이용률이 해마다 급증하고 있다. 이처럼 전자금융의 대중화 및 활성화로 인해 전자금융사고에 의한 이용자의 금전적인 손실은 해당 금융기관의 신뢰도 하락과 경영상 피해 등 과거보다 더 심각한 영향을 줄 수 있다. 따라서 본 논문에서는 다변화하는 전자금융 환경에 대해 살펴보고 인터넷, 모바일 및 자동화기기 등 전자금융에서 발생한 또는 발생 기능한 보안위협을 분류함으로써 향후 이를 기반으로 전자금융 서비스 안전성 강화를 위한 대응 방안 연구에 기반이 되고자 한다.

블록체인을 포함하는 분산원장기술은 신뢰할 수 없는 네트워크 상에서 공동으로 거래 정보를 검증하고 기록, 보관함으로써 원장의 무결성과 신뢰성을 제공하고 있다. 이러한 분산원장기술을 이용한 제반 응용시스템이 실세계에서 적용되고 확산되기 위해서는 거버넌스 체계가 구축되어야 한다. 일반적으로 거버넌스란 특정 조직내에서의 지시와 통제활동이라고 할 수 있는데, 분산원장시스템의 경우, 다양한 조직 또는 시스템을 포함하고 있으며 거버넌스 체계도 분산 또는 탈중앙화된 형태로 존재하므로 기존의 조직 거버넌스 체계와 다른 특성과 한계를 가지고 있다. 본 연구에서는 ISO TC 307에서 진행하고 있는 분산원장시스템 거버넌스 표준화 활동을 소개하고 향후 전망과 대응방안을 검토한다.
