협업 필터링 기술은 명시적 피드백이 아닌 암시적 피드백이 주어졌을 때 다음과 같은 문제 (단일-클래스 협업 필터링 문제)를 갖는다. (1) 사용자의 취향을 정확하게 파악하기 어렵다; (2) 상대적으로 더 희소(sparse)하다. 최근, 이러한 단일 클래스 협업 필터링 문제를 완화하기 위해, 사용자가 관심이 없을 것으로 예상되는 무관심 상품을 추가로 활용하는 기술이 제안되었다. 그러나, 이 기술은 무관심 상품을 찾는 과정에서 사용자들이 평가하지 않은 상품에 대한 선호 정도를 추론할 때 한 가지 기술만을 사용하였다. 본 논문에서는, 다양한 기술들을 기반으로 무관심 상품을 찾은 후 각 기술에 의한 무관심 상품의 정확도를 비교함으로써, 어떠한 기술이 무관심 상품 결정에 가장 효과적인지를 분석하고자한다.

Despite a copious volume of work on the relationship between social class and cultural consumption, scholars have paid scant attention to the increasingly apparent observation that a vast majority of the population exhibits indifference toward fine arts regardless of one's socio-economic status. Much of the prior literature on cultural consumption has treated the public's indifference to fine arts not as a distinct analytical category that deserves an explanation of its own, but simply as the opposite of "likes" or the act of consumption, let alone being disentangled from the concept of "dislikes" in taste-formation and consumption behavior. In this paper, we suggest that the seemingly increasing trend toward indifference to fine arts, especially among those who are part of the well-educated and economically well-off, merits close scholarly attention on its own term. As an initial step toward this endeavor, we explore the factors behind indifference toward fine arts among Korean middle-class, using the ground theory method. Our interview findings reveal that much of indifference toward fine arts is attributable to the lack of tastes in fine arts and artistic competence. Our results suggest that research drawing on Bourdieu's theory and Peterson's omnivore hypothesis needs to be further revised through an in-depth investigation of the institutional and societal contexts where art education takes place in Korea. We discuss the implications of our findings for policy-making in the cultural and artistic sphere.

The purpose of this study is to find an answer why internet users are unconcern about their privacy information. We found that perceived privacy risk and website usability have a significant effect on privacy unconcern. That is, individuals who have experiences privacy incidents are more likely to be unconcern about their privacy information. Accordingly, organizations who supply services on the web have to pay more attention to these individuals to increase a privacy concern. Implications and Conclusions are discussed.

This study is to explain why internet users are unconcerned with their privacy information. For this purpose, this study focuses on the Nate.com case. Nate.com recently suffered from external intrusion. They announced this fact to their users. However, users did not leave the Nate.com. To explain the reason, this study used a combination of qualitative and quantitative techniques. The grounded theory approach was used to analyze responses to open-ended questions answered by 240 Nate.com users. Using these responses, a survey instrument was developed. Survey results were analyzed using structural equation modeling. The conclusions and implications are discussed.

부모의 사랑은 가정환경을 통하여 자녀의 대인관계나 사회화에 있어서 최초의 모델이 될 수 있고 자녀의 성격형성이나 문제행동에 깊은 영향을 준다. 이 연구는 청년기 자녀의 잠재된 갈등요인 즉 청년들에게 영향을 주는 요인이 무엇인가를 면접조사와 TAT를 통한 방법으로 시행하였다. 면접조사 결과 부모는 거부적 과보호, 무관심으로 청년들의 갈등을 일으키고 형제간의 갈등이 있는 것으로 나타났다. TAT결과는 부모상에서 부모의 모습은 무관심하거나, 간섭이 심하고 강요적이었으며 환경반응은 가족간의 사랑과 이해가 없는 경우로 나타났다. 불안 갈등요인도 형제간의 갈등, 부모에 대한 사랑의 부족, 결핍 등으로 나타났다.
