기업과 소비자간 일대일 상호작용을 가능하게 하는 전자상거래의 기술적 발달을 통해 소비자에게 더 나은 웹 경험을 제공하기 위해 개인화 서비스를 제공하고 있다. 개인화 추천을 수행하기 위해서는 추천을 받을 사용자와 유사한 다른 사용자들의 선호도를 반영하는 협업 필터링 기법이 많이 활용되고 있으며, 많은 사이트들이 추천을 받은 사용자에게 유사한 사용자들을 보여주어 사회망 연결을 위한 기회를 제공하고 있다. 본 연구에서는 웹 기반 개인화 추천 시스템을 이용하여 사용자에게 효과적으로 제품을 추천하기 위해서, 사회적 실재감(Social Presence)이 추천시스템의 만족도에 미치는 영향에 관하여 연구하고자 한다. 또한, 사회적 실재감을 높이기 위한 방안으로 사회망(Social Network) 데이터의 제시를 통해 다양한 차원의 사회적 실재감과 추천시스템에 대한 만족도 및 신뢰간의 영향관계를 분석한다. 이를 위해 실험집단을 나누어 세 가지 차원의 사회적 실재감을 부여하고, 집단간의 추천 시스템에 대한 신뢰와 만족도간에 차이가 있는지를 분석하였다.

This study is intended to identify the relationship between antecedents and performance factors that affect the knowledge-sharing of financial professionals. In order to accomplish the objective, antecedents were established as 'disposition to trust', 'subjective norm', and 'knowledge-sharing willingness' in the personal aspect, and 'trust in peers' and 'management support' in the organizational aspect. As performance factors, 'job satisfaction' and 'firm innovation' were established, and a research model was presented. Empirical analysis was done on the research model using collected questionnaires from 185 financial professionals. The research findings are as follows. First, disposition to trust of financial professionals has a positive effect on their knowledge-sharing.

This study analyzed the causal relationship among factors that influence the purchase intensions for individual pensions which have a growing importance as a financial means after retirement. For this purpose, structural equation modeling based on the survey data (N = 928) was conducted to analyze psychological factors and financial factors comprehensively. According to empirical results of the structural equation, in the case of non-subscribers of individual pensions, potential longevity and coping efficacy influenced the purchase intensions for individual pensions fully mediated by fear and worry about longevity. Trust in insurers and risk tolerance directly influenced the purchase intensions for individual pensions. These show that trust in insurers is the most important factor in purchase intensions for individual pensions. Also, only trust in insurers give a direct impact on individual pensions in the case of individual pension subscribers. Longevity-related emotional side is expected to help in marketing activities that target potential customers signing individual pensions. In addition, trust in insurers has the greatest impact on new and additional subscriptions that represent critical efforts to improve trust in insurers.

Data were collected from 770 students from A University in Gyeonggi-do, H University in the Daejeon, and K University in Chungcheong-do, and analyzed by using structural equations modeling. As results, individual creativity had significant influence on collective efficacy and collective intelligence. Team trust also had significant influence on collective efficacy and collective intelligence. In addition, collective efficacy had a positive effect on collective intelligence.

eID는 여러 편의성을 제공하지만, 개인정보보호의 불확실성에 대한 우려로 활성화가 쉽지 않다는 단점이 있다. 이미 선진국에서는 eID의 도입을 추진해 왔으며 특히 EU에서 적극적으로 시도한 바 있다. 안전한 eID 시스템을 위해서는 개인정보보호 뿐 아니라 시스템 자체의 보안에 대한 고려도 동시에 이루어져야 한다. 보안성이 신뢰되지 않는다면, 개인정보보호에 대한 신뢰도 존재할 수 없을 것이다. 본 고에서는 EU에서도 특히 활발한 움직임을 보이고 있는 독일의 eID 현황 및 보안 메커니즘을 살펴본다. 그리고 안전한 eID 시스템 구성을 위한 보안 요구사항을 분석한다.

Personal Software Process (PSP)에서 개인 개발자들이 수행해야 되는 측정 및 분석 활동이 제시된다. 측정 및 분석 활동의 일관되고 지속적인 수행으로 개발자들은 소프트웨어 품질 향상, 보다 정확한 예측, 개인 역량의 객관적인 평가, 개인 프로세스의 정량적 관리 등의 이득을 얻을 수 있다. 측정 및 분석 활동에서 신뢰성 있는 데이터의 수집이 무엇보다 중요하다. 하지만, 데이터 수집의 높은 오버헤드(overhead)와 컨텍스트 스위칭(context switching)의 문제로 인하여 신뢰성 있는 데이터의 수집에 많은 어려움이 존재한다. 이러한 어려움을 감소시키기 위해 자동 데이터 수집 및 분석 기법이 연구되어 왔다. 본 논문에서는 기존의 자동 데이터 수집 및 분석 기법을 확장하여 웹 애플리케이션 개발에서의 개인 프로세스 데이터를 자동 수집 및 분석 하는 도구를 설명한다.
