정보기술의 발달로 정보를 수집, 관리, 공유하기가 용이해 짐에 따라 여러 조직이나 기관에서는 개인정보를 수집해 관리하고 있다. 수집한 개인정보를 통계나 연구 등을 목적으로 배포할 때 개인의 프라이버시를 보호하기 위해 k-anonymity 와 l-diversity 원리가 제안되었고 이를 기반으로 하는 프라이버시 보호 기법들이 제안되었다. 그러나 기존 방법들은 정적인 데이터를 단 한번 배포하는 것을 가정하기 때문에 지속적으로 데이터에 삽입이나 삭제가 발생하는 동적 데이터 환경에 그대로 적용하기 적합하지 않다. 본 논문에서는 동적 데이터 환경에서 l-diversity 을 유지하면서 데이터 삽입과 삭제를 효율적으로 처리할 수 있는 기법을 제안한다. 제안 기법은 일반화를 사용하지 않기 때문에 일반화에서 발생하는 정보의 손실이 발생하지 않고 삽입과 삭제의 처리가 간단한 것이 특징이다.

Many organizations are applying robotic process automation (RPA) to automate repetitive and rule based tasks to enhance the accuracy and efficiency of works. Some members are willing to join the projects hoping to eliminate annoying and meaningless tasks, but others are resisting this innovation fearing that they may lose their jobs. In this study, both positive and negative antecedents are posited to influence the performance in adopting RPA. The effects of relative advantage, compatibility, change management effect, innovation resistance and satisfaction, conclusively to performance improvement were examined via a survey of 109 employees involved in the 11 RPA projects in a manufacturing company, and the structural equation model analysis. The research considering the consumer characteristics of the innovation resistance model can be followed for the development of individualized change management strategy.

소프트웨어에 이어 하드웨어에서도 오픈소스시대가 열리고 있다, 소프트웨어와 하드웨어 분야에서의 오픈소스의 폭넓은 확산은 ICT 분야의 R&D 활동에서 새로운 연구 방법과 연구 분야의 확장을 가능케 할 것으로 생각된다. 오픈소스 생태계 하에서는 개별 연구조직의 크기나 연구 규모에 따른 장점은 줄어드는 반면 개인의 창의력이나 협업 능력이 연구경쟁력의 원천이 된다. 이에 따라 과거에는 시도하지 않았던 창의적인 선행연구나 시스템적인 융합연구도 가능해질 것이다. R&D는 단지 구현결과물을 얻는 것에 한정되는 것이 아니라, 개념 도출, 이에 따른 설계, 소프트웨어 및 하드웨어 구현, 적합성 및 상호운용성시험, 대규모 실증사업까지의 단계적이고 체계적인 추진과 이에 대한 문서화, 규격화 및 표준화 작업들을 포함한다. 이러한 작업은 순차적이 아니라 동시적으로 수행될 때 상호연계 검증에 따른 완성도 제고와 전주기 활동에 있어 총 시간 단축을 꾀할 수 있다. 본 고에서는 오픈소스 생태계에서 연구자들이 이러한 활동의 효과적인 수행과 협력적 융합연구를 위한 저비용 오픈소스 R&D 동시개발 플랫폼 방안을 제시한다.

The purpose of this study is to inquire into the effect of characteristics of public enterprise CEOs' leadership (transforming leadership and transactional leadership) on the leader trust and organizational effectiveness of organizational members. A survey was made on 1,124 persons being in the service of 14 marketable and quasimarketable public enterprises. The results of this study were as follows. First, it showed that the individualized consideration had an effect on the confidence level of leader. Second, it showed that the transforming and transactional leaderships had an effect on the organizational effectiveness, which the hypothesis was adopted. Third, it showed that calculable, intellectual and identical factors had a positive effect on the job satisfaction and organizational commitment, but the organizational commitment of calculable variable was rejected in the confidence level. In general, the effect of transforming and transactional leaderships as public enterprise CEOs' leadership characteristics on the organizational effectiveness by mutual confidence level of calculable, intellectual and identical standards showed that the organizational commitment was rejected in the base of identification. And other factors were adopted as a positive mechanism, which they were a mechanism suitable to public enterprise CEOs' leadership characteristics.

The use of SNS (Social Network Service) has been increasing in world society and the SNS has been used to satisfy different purposes of social groups over the years. In the beginning, the SNS were formed using e-mail, listserve, newsgroup, etc., where information was shared among relatively homogeneous groups of people. Now different groups including corporations have been using SNS such as personal web pages, blogs, Facebook and Twitter for their social media marketing. This study intends to verify the relationship between SNS use and export marketing performance. To achieve this, different types of SNS use were analyzed in order to verify their relationship with export marketing performance. The conceptual model is suggested in this paper and several research constructs are identified. The constructs used in this paper include export marketing performance, SNS use, degree of innovation, product online fitness, marketing competence, and internationalization competence. According to the results, the SNS use directly influences the export marketing performance. In addition, the factors which determine the level of SNS use are product's online fitness and organizational willingness to undertake innovation. Therefore, it is suggested to increase SNS use in different marketing purposes for future research.

This study investigates the effects of individual and group level factors on the use of GSS (Group Support System) and task performance from GSS use. GSS facilitates the group work, so that GSS adoption is not necessarily influenced only by individual perceptions on information systems. Adaptive Structuration Theory (AST) in our study to explain the adoption and success from GSS use. AST contends that the success of IS is not necessarily the technical fit between tasks and technology, instead the political outcome among user socializations. We have the following two research inquires: Are the IS use and performance maximized when information technologies are provided properly?; and, Does TTF always influence positively on IS use (or performance)? To research these issues, we investigate the influence of TTF (Task-Technology Fit) on use and performance of GSS, which is introduced to foster collaboration among organizational members. Drawing insights from the AST, we examine if COA (Consensus on Appropriation) among group members and FOA (Faithfulness of Appropriation) between those who use technology and who design it show any moderating effect. A questionnaire survey was conducted on firms using the GSS for one month from June 2 to June 27 2005 and a sample of 303 responses was used for a statistical analysis. The result demonstrates that TTF exerts a positive influence on use and performance of GSS. We find that the stronger the COA, the greater the effect of W on use of GSS and performance. FOA likewise has a positive effect on both use of GSS and performance. The TTF model has been widely applied to studies on individual performance of information system, whereas the AST theory specifically explains members' adaptation process to information system. By integrating the AST theory with the TTF model, the study contributes to heightening our understanding on if and how individual performance varies with the use of GSS.
