The Purpose of this Paper is the development of the day-to-day dynamic combined model on the evaluation of traveller's traffic information for multi-mode and multi-class environments. Information is assumed to be provided for multi-mode such as bus and automobile. and multi-class such as a driver with and without route guidance equipment when they depart for their trips. The information provision strategies have been developed in the base of user equilibrium, system optimum and in between them. The Sioux Falls network is used for the evaluation of the model and information provision strategies. In the numerical analysis, a Braess' paradox for the information provision, which is the increase of travel time even though the number of information usage level and user are increased, has been occurred so that these kinds of information strategies should be implemented with special care.

The purpose of this study is to determine how the factors that form the spatiality of an idle space affect the behavioral intention of tourists, and to confirm the role of local participation between the spatiality-forming factors and behavioral intentions. For this purpose, data from travelers was gathered and the study model was put to the test. As a result of the study, it was confirmed that physical factors, behavioral factors, and psychological factors had a significant effect on the intention of tourists. In addition, it was confirmed that local participation partially plays a mediating role between the spatiality-forming factors and behavioral intentions. According to the results of the study, the necessity of local participation and the measures were discussed when using the idle space, and it was suggested that additional research needs to be carried out targeting various idle spaces.

Due to the recent technological improvements, the environments of e-books and its contents have been changed and the users of e-books have drastically increased. This study aimed to propose a model on how children access and search e-books in this digital era. For this study, a potential model was proposed based on the analyses on various information-seeking behavior models. For analyzing children's access and search processes on e-books, 30 children in five public libraries or school media centers in Seoul and Kyoungi-do areas were recruited for the in-depth interviews. As a potential model on children's access and search on e-books was re-visited and revised based on the results, a cyclic model of children's access and search on e-books was proposed containing six factors.

인터넷의 확산과 함께 금융 산업에서 인터넷뱅킹의 등장은 은행 산업 전반에 많은 변화를 가져오고 있다. 인터넷뱅킹은 더 이상 단순한 정보시스템이 아닌 은행의 경쟁력을 결정짓는 중요한 요소로 부각되고 있다. 또한 국내 인터넷뱅킹 사용자의 증가로 인해 은행에서는 기존 인터넷뱅킹 사용자가 지속적으로 인터넷뱅킹을 이용할 수 있도록 여러 가지 전략을 개발하여야 할 것이다. 따라서 본 연구에서는 정보시스템 연구 분야에서 기술 수용에 대한 많은 연구들의 이론적 기반이 되었던 계획적 행동 이론(TPB)과 기술 수용 모델(TAM)을 인터넷뱅킹 이용의도 분석에 적용시켜 인터넷뱅킹 이용 행위를 실증 분석함으로써 지속적인 인터넷뱅킹 이용 의도에 영향을 미치는 요인들을 규명하고자 하였다. 더 나아가 TPB 모형과 TAM 모형을 체계적으로 비교분석하여 인터넷뱅킹 이용의도에 관한 이론적 기초를 제시하고, 인터넷 환경에서 은행의 적극적인 인터넷뱅킹 활용에 도움이 될 수 있는 실무적 시사점을 제공하고자 한다.

최근 증강현실 기술은 산업 분야뿐만 아니라 교육 분야에서도 많은 인기를 끌고 있다. 특히 유아 교육용 콘텐츠에서 특정 장면을 인식하고 장면에 해당하는 3차원 모형이 나타나는 형태는 아이의 호기심 자극하여 높은 교육효과를 나타내고 있다. 하지만 현재 증강현실 기술을 사용한 콘텐츠에서는 해당 장면에서 같은 내용만 나오기 때문에 반복적인 이용하는 경우에는 사용자가 지루함을 느끼는 문제점이 있다. 이를 보완하기 위해 사용자의 행위를 반영하는 증강현실 콘텐츠 제작하기 위하여 사용자의 행위가 반영된 마커 이미지를 실시간으로 추출하는 기법을 구현하고 실험하였다.

The present study aimed to investigate the information needs and information seeking behavior of consumers who attempted to quit or maintain the ceasing of smoking and analyze the effects of the health information obtained at different stages. In particular, we examined how consumers use mobile health applications(health apps) as aids to change unhealthy behaviors and how their use of health apps influence health behavior changes. For 7 months from December 2017 to July 2018, the researchers observed changes in smoking behaviors of college students who use smoking-cessation apps and conducted face-to-face interviews. Regarding the effects of smoking-cessation apps, the participants in the action stage reported that they were encouraged to quit smoking by visualized information such as the number of days of smoking cessation, change of health status, and the saving of money due to smoking cessation. The participants in the maintenance stage highlighted that smoking cessation apps were helpful in recognizing the importance and achievement of smoking cessation by sharing experiences and social support with other attempters in the app community. The study provided theoretical implications in the field of information behavior in that it identified the particular types of information needs and information-seeking behavior of the consumers who were using mobile apps in their behavior modification process. In addition, those findings can contribute to designing the contents of the smoking cessation apps that reflect the information needs of those who attempt to cease smoking and further suggest practical insights to health information services that promote effective information intervention strategies in health behavior change.

According to the recent statistics of the National Industrial Security Center, about 80% of the confidential leak are caused by former and current employees in the case of domestic confidential leak accidents. Most of the information leak incidents by these insiders are due to poor security management system and information leak detection technology. Blocking confidential leak of insiders is a very important issue in the corporate security sector, but many previous researches have focused on responding to intrusions by external threats rather than by insider threats. Therefore, in this research, we design an internal information leak scenario to effectively and efficiently detect various abnormalities occurring in the enterprise, analyze the key indicators of the leak symptoms derived from the scenarios by using data analytics and propose a model that accurately detects leak activities.

Recently, due to the popularity of object-oriented programming languages, object-oriented modeling and development methodologies become widely applied to information system development. When object-oriented methodology is adopted, using object-oriented modeling languages for business analysis and redesign has the advantages such that business modeling results can be easily understood and referred by information system developers. In this paper, UML-B, Unified Modeling Language extension for Business modeling is proposed, which uses UML notation for modeling organization structure, actors, use cases, business processes, and entities in business systems. It also utilizes extension mechanisms of UML to facilitate business modeling activities, and supports business process reengineering with object-oriented modeling.

인터넷이 본격적으로 상거래목적으로 사용된 이후로 전자상거래 활성화의 큰 장애요인으로 작용하고 있는 것 중의 하나는 소비자 신뢰라고 할 수 있다. 전자상거래에서는 상품을 보거나 만질수도 없고, 상품을 판매하는 상점의 위치도 알기 어려우며, 인터넷이라는 가상의 공간에서 상품을 판매하고 구매하는 행위가 일어난다. 이런 특성 때문에 소비자 신뢰가 중요하다고 할 수 있다. 이 연구에서는 소비자 신뢰에 영향을 미치는 선행요인에 대한 이론적 연구 모형을 제시한다.

The purpose of this study propose and empirically assessed Internet Banking success model. This was derived through an analysis of the quality evaluation factors of Internet Banking services and review of TAM model, IS success model, e-Commerce success model literature. The research model consists of exogenous variables(ease of use, economic benefits, safety) and endogenous variables (usefulness, user satisfaction, trust, behavioral intention to use). The analysis results revealed that ease of use is a very significant factor influencing usefulness and user satisfaction, trust. Safety is a significant factor influencing trust. Economic benefits and usefulness, trust are significant factors influencing user satisfaction. Usefulness and user satisfaction are significant factors influencing behavioral intention to use. This study provide the initiative of Internet Banking success model. Internet banking firms will support the competitive service through strategic qualify evaluation and improvement using Internet Banking success model.
