The purpose of this paper is to examine the effect of interpersonal face-to-face offline on identification-based trust and reciprocity norm in online world, and the effect of identification-based trust and reciprocity norm on the intention and behavior of sharing information in online world. To understand the moderating role, the importance of information was established as a moderating variable, and an empirical analysis was conducted, focusing on the undergraduate. The results of this study are as follows. It was found that interpersonal face-to-face in offline world affects identification-based trust and reciprocity norm in online positively. A reciprocity norm of identification-based trust and reciprocity norm in online world affected by interpersonal face-to-face in offline world has a positive effect on the intention and behavior of sharing information in online, but showed that identification-based trust does not affect them significantly. And reciprocity norm has significant relationship with information sharing behavior through the intention to share information. It was found to be a partial moderating effect of importance of information on the relationship among the reciprocity norm and the intention and behavior of sharing information.

본 논문에서는 온라인 뉴스 기사를 여과하여 사용자에게 관련있는 뉴스기사만을 선별적으로 여과하여 보여주는 정보여과 에이전트를 설계 및 구현하였다. 정보여과의 핵심이라고 할 수 있는 정확한 사용자 프로파일 구축과 정보에 대한 사용자의 적합성 반응인 명시적 피드백과 암시적 피드백을 모두 결합한 피드백을 사용하여 사용자 프로파일을 좀 더 정교하게 구축하는 방법을 기술하였다. 실험을 통하여 사용자의 결합된 적합성 피드백 행동에 기반한 정보여과 에이전트의 성능이 단일의 피드백만을 사용했을 때보다 더 좋은 정확성과 적응성을 지니고 있음을 보여 주었다.

This study aims to develop a research methodology course for graduate-level students using an information-seeking behaviour model of distance learners. Based on a case study and structured survey, the factors that motivate and hinder information-seeking behaviours were identified. The motivating factor for students seeking information through the research methodology course was the necessity to obtain a master's degree, while the hindering factor was the challenge of balancing work and study. The course was developed by leveraging motivational factors and addressing hindering factors. The results of this study can serve as foundational data for understanding students' information-seeking behaviour and establishing teaching and learning strategies to enhance students' information-seeking skills when developing online courses.

In the post-pandemic era, the demand for online education platforms has surged, leading to increased consumer reliance on online reviews for decision-making. This study investigates the impact of Chinese online customer reviews on consumer purchase behavior in online education. By examining the role of trust, review sentiment, and the quantity and timeliness of reviews, the research aims to understand how these factors influence consumer decisions. By using regression model, findings reveal that negative reviews, timely feedback, and a higher volume of reviews positively affect consumer purchase decisions, while course pricing demonstrates an inverse relationship. Furthermore, cognitive and affective trust mediate the relationship between reviews and purchase behavior, highlighting a reverse U-shaped effect on consumer decision inclination. These insights provide valuable implications for online education providers, emphasizing the need to manage and leverage online reviews to foster consumer trust and improve sales performance.

This paper deals with the online privacy policy, which is designed to solve the information asymmetry problem between websites and internet users. We empirically analyze the recognition, confirmation of the online privacy policy, and its effects on online transaction behavior using a rich survey data representing 5,422 Korean internet users. Major results are as follows. First, there exists a significant difference between recognition and confirmation, and confirmation behavior is positively related with the importance of privacy issue and the experience of privacy invasion. Second, binary variable regressions show that internet user tends to participate in online transaction if he/she confirms the online privacy policy positively. Finally, if websites would make online privacy policy easy and short, a yearly online transaction market size of Korea would increase by 0.46 million participants and 22.4 billion KRW.

강화 학습은 누적 보상 값을 최대화할 수 있는 행동 선택 전략을 학습하는 온라인 학습의 한 형태이다. 효과적인 강화학습을 위해 학습 에이전트가 매 순간 고민해야 하는 문제가 탐험(exploitation)과 탐색(exploration)의 문제이다. 경험과 학습이 충분치 않은 상태의 에이전트는 어느 정도의 보상 값을 보장하는 과거에 경험한 행동을 선택하느냐 아니면 보상 값을 예측할 수 없는 새로운 행동을 시도해봄으로써 학습의 폭을 넓힐 것이냐를 고민하게 된다. 특히 단일 에이전트에 비해 상태공간과 행동공간이 더욱 커지는 다중 에이전트 시스템의 경우, 효과적인 강화학습을 위해서는 상태 공간 축소방법과 더불어 탐색의 기회가 많은 행동 선택 전략이 마련되어야 한다. 본 논문에서는 로봇축구 Keepaway를 위한 효율적인 다중 에이전트 강화학습 방법을 설명한다. 이 방법의 특징은 상태 공간 축소를 위해 함수근사방법의 하나인 타일 코딩을 적용하였고, 다양한 행동 선택을 위해 룰렛 휠 선택 전략을 적용한 것이다. 본 논문에서는 이 방법의 효과를 입증하기 위한 실험결과를 소개한다.

온라인거래가 폭발적으로 증가하면서 온라인결제에 대한 이용자 수요가 증가하고 있다. 특히 최근 들어 온라인소액결제는 다양한 디지털재화(MP3, VOD, 사이버머니 등)를 구입하는 데 활발하게 사용되고 있으며, eBay의 PayPal, 구글의 Checkout 등 해외에선 이미 차세대 온라인 비즈니스 영역으로 주목 받고 있다. 온라인소액결제는 전자 상거래에서 사용되는 결제 방식으로 금액이 작은 온라인 거래에서 사용되는 결제를 말한다. 하지만 온라인소액결제에 대한 국내외적인 성장에도 불구하고 이 분야에 대한 연구는 거의 전무한 상황이다. 본 논문에서는 온라인소비자들이 온라인 환경에서 소액결제를 이용할 때, 선호하는 결제수단과 중요시 여기는 속성에 대한 실증연구를 진행했다. 온라인 소액결제는 연령층에 따라 신용카드 결제와 상품권, 사이버머니 등의 결제 선호로 나뉘어 지고, 개인정보 보장 등과 같은 안전성에 관련된 속성을 중요시 하는 것으로 나타났다. 이와 같은 결과는 향후, 온라인 소액결제에 대한 소비자 특성과 도입 및 발전전략에 대한 다양한 해석을 통해 이비즈니스 분야에 실질적으로 활용될 수 있을 것이다.

The purpose of this research was to find differences of children's behavioral pattern between players and non players of the online game "Lineage" in on-line and off line space. As a result, social behaviors of children who play online games were less active than who don't. Based on their motive and behavior pattern in online world, four behavior patterns in online world were identified; "Single-Oriented", "Community-Oriented", "Off-Real World" and "Discriminative." Off-Real World and Discriminative players were more sociable than Single-Oriented and Community-Oriented players. And Discriminative player has more self assertive attitude than others. This study may serve as a model to understand how players will respond to the various game features and how they adopt the virtual world for their interpersonal relationships.

Consumers tend to trust information provided by other consumers more than information provided by sellers. Therefore, while inducing consumers to write high-quality reviews is a very important task for companies, it is not easy to produce such high-quality reviews. Based on previous research on review writing and memory recall, we decided to develop a way to use digital nudge to help consumers naturally write high-quality reviews. Specifically, we designed an experiment to verify the effect of uploading a photo during the online review process on the quality of review of the review writer. We then recruited subjects and then divided them into groups that upload photos first and groups that do not. A task was assigned to each subject to write positive and negative reviews. As a result, it was confirmed that the behavior of uploading a photo first increases the review length. In addition, it was confirmed that when online users who upload photos first have extremely negative satisfaction with the product, the extent of two-sidedness of the review content increases.
