This paper analyzes the impact of information breach on shareholder value by measuring the stock price reaction associated with the announcements of data breach. The breach firms in the sample lost, on average, 1.3% of their market value, amounting to 98.9 million won of loss within two-day of the event period after the announcement. We examine the abnormal returns in various categories (i.e., source, type, size, etc.) of information breach. Although the market does not react significantly to the announcements of outside breach, we find statistically significant market reactions to inside breach. We estimate abnormal returns over the following 60 days. The mean 60-day cumulative abnormal return and BHAR (buy-and-hold abnormal returns) are both significantly far from zero. We conclude that there is a coherent market reaction following the announcement. The difference between the market reactions to IT firms and Non-IT firms is statistically significant. But breach amount, firm size, and the year the breach occurred do not show to be significant variables.

In this study, we have examined how the potential users of IT convergence product use the external information sources for purchasing decision focusing on a case of smartphone. Although the specifications and price of IT convergence products, such as smartphone, tablet pc, and smart TV, are considered as major criteria for purchasing decision, the competitiveness of these factors have disappeared as many companies launch similar products in the market. External information sources play a significant role to differentiate the alternatives by offering value-added experience information. The effect of external information sources becomes stronger for experience and high-involvement product whose performance can be evaluated through only users' direct experience. In this study, we categorized the external information sources for smartphone into five; company ads, personal network, expert group, consumers, and media. Through an empirical study with potential smartphone users, we verified how these external information sources affect users' purchasing decision in the perspective of the perceived attributes of information source, quality of information, and individual's characteristics based on self-regulatory theory.

This study examined the effects of cosmetic selection attributes on consumers' purchase propensity and recommend intention. In addition, the moderating effect according to the consumer's deal proneness was verified. Finally, a multi-group analysis was conducted to verify the difference in the research model path according to the information source. Through this study, the selection attributes of consumers who purchase cosmetics were clarified. This study aims to meet the needs and demands of the related industry for more detailed and effective strategic insights by clarifying the structure of the influence of these selection attributes on purchase intention and recommendation intention according to the discount purchase intention. In order to achieve the research objectives due to this necessity, a questionnaire of 258 Korean female consumers was collected and used for research. The analysis results showed that product selection attributes, purchase intention, and recommendation intention all had a positive influence. As a result of analyzing the moderation effect according to the consumer's Deal Proneness, the results showed a moderating effect between the selection attribute and the purchase propensity, the selection attribute and the recommend intention, and the purchase propensity and the recommend intention. Finally, it was partially adopted as a result of conducting a multi-group analysis to verify whether individual paths of the model differ according to information sources.

산업 전반에 적용되는 과학, 공학 분야에는 그 목적에 따라 다양한 형태의 정보가 발생한다. 정보는 이용하는 목적에 따란 가공하는 형식과 표현하는 방식이 달라지며, 정보에 직접적으로 접근하는 사용자에게 어떻게 효과적으로 전달할 것인가 하는 문제는 정보 관리 분야에서 매우 중요한 이슈가 되고 있다. 정보를 사용자에게 보다 명확하게 전달하고, 관리하기 위해서는 원천 데이터를 가공하여 가시화(visualization)하는 과정을 거친다. 정보가시화는 원천데이터를 데이터모델로 정리한 후, 가시화구조(visual structure)로 재정의 한다. 실질적인 가시적 결과는 가시화 구조의 데이터들을 정보모델(information model)상에 반영할 때 이루어진다. 본 논문에서는 건물내부에서 진행되는 행사에 대한 시간-공간적인 정보를 정리한 도표 메타포(table metaphor)를 초기 데이터 모델로 사용하여 가시화 하는 과정을 수행한다. 정보 가시화 과정과 저작 과정은 증강현실(augmented reality) 환경에서 이루어진다. 행사가 진행되는 장소의 건물 구조도(map)상에서 각 장소에서 발생하는 정보들을 재배열하고 정리함으로써, 저작자로 하여금 정보 그 자체에 대한 이해뿐만이 아니라, 해당 정보에 대한 공간적인 이해도 함께 가능하게 한다. 이 같은 몰입형(immersive) 저작시스템은 정보에 대한 공간적인 분배가 필요한 저작에서는 매우 유용하며, 저작하는 환경 자체가 가시화의 결과물이 되므로 정보 저작에 대한 가시적 이해를 최대화 시킬 수 있다.

Reputation systems aggregate users' feedback after the completion of a transaction and compute the "reputation" of products, services, or providers, which can assist other users in decision-making in the future. With the rapid growth of online e-Learning content providing services, a suitable reputation system for more credible e-Learning content delivery has become important and is essential if educational content providers are to remain competitive. Most existing reputation systems focus on generating ratings only for user reputation; they fail to consider the reputations of products or services(item reputation). However, it is essential for B2C e-Learning services to have a reliable reputation rating mechanism for items since they offer guidance for decision-making by presenting the ranks or ratings of e-Learning content items. To overcome this problem, we propose a novel collaborative filtering based reputation rating method. Collaborative filtering, one of the most successful recommendation methods, can be used to improve a reputation system. In this method, dual information sources are formed with groups of co-oriented users and expert users and to adapt it to the reputation rating mechanism. We have evaluated its performance experimentally by comparing various reputation systems.
