Cloud computer technology currently provides diverse services based on a comprehensive environment ranging from hardware to solution, network and service. While the target of services has been extended from institutions and corporations to personal infrastructure and issues were made about security problems involved with protection of private information, measures on additional security demands for such service characteristics are insufficient. This paper proposes a multi-session authentication technique based on the characteristics of SaaS (Software as a Service) among cloud services. With no reliable authentication authority, the proposed technique reinforced communication sessions by performing key agreement protocol safe against key exposure and multi-channel session authentication, providing high efficiency of performance through key renewal using optimzied key table. Each formed sessions have resistance against deprivation of individual confirmation and service authority. Suggested confirmation technique that uses these features is expected to provide safe computing service in clouding environment.

인간 사이의 상호작용이 증대됨에 따라 명함과 같은 인적 정보의 교환도 더욱더 많아지고 있으며 이에 따른 효율적 사용과 관리에 어려움이 커지고 있다. 그러므로 인적정보를 디지털화하여 실세계와 사이버세계를 연결하여 관리할 수 있다면 보다 다양하고 편리한 서비스를 이용할 수 있을 것이다. 본 논문에서는 컬러 코드를 이용한 온.오프라인 통합 개인정보 관리 시스템인 CPIMS(Colorcode personal Information Management System)를 개발하였다. 사용자는 컬러 코드가 인쇄된 명함을 받았을 때 명함 중인의 개인 정보를 주소록에 자동으로 입력 받을 수 있게 된다. 그리고 명함주인의 정지화상 및 동영상이나 음성메시지 등과 같은 부가 정보도 제공받을 수 있는 특징을 가진다. 이러한 원리는 명함에 부착된 컬러 코드를 PC 카메라를 사용하여 인식하게 하고 상응하는 정보를 데이터베이스에서 불러오는 것이다. PC 카메라의 보급과 PDA, IMA-2000 등의 카메라가 장착되는 이동컴퓨팅 장비의 사용이 확대되고 있으므로 본 논문에서 제안한 시스템은 온.오프라인을 통합하는 효과적인 미디어 시스템이 될 것으로 기대된다.

The purpose of this study is to highlight the effects of the two leadership styles, namely: transformational leadership and transactional leadership, on the different types of followership through analyzing their impact in the productivity and competitiveness of human resources in IT SMEs. The paper focuses on determining whether transformational leadership or transactional leadership is more effective as shown by the levels of empowerment derived from these two types of leadership under study. From this study, alien, role model and passive types of followership, transformational leadership appears to be more influential for personal empowerment. As for group level of empowerment, the transformational type of leadership shows higher effectiveness in alien, role model, passive, and practical types of followership. On the other hand, transactional leadership yields positive impact on practical and conformist types of followership. In summary, personal empowerment plays a direct impact on group empowerment. Thus, with the exception of conformist type of followership, transformational leadership has more impact in human resources of IT SMEs.

Social networking service (SNS), which is based on the "six degree separation" theory, has gained its popularity in recent years. SNS creates a new way for maintaining relationship and sharing information over the virtual space. As a major branch, campus SNS provides a new platform for student to study as well as build and maintain inter-personal relationships. The highly realness of personal information and relatively strong group cohesion of campus SNS has turned it into an inevitable tool in students' daily life. The rapid growth of SNS in campus is creating huge academic and commercial benefits. However, little comprehensive research reveals what are determinant factors in driving students' intention to participate in campus SNS. In this paper, we conceptualize the participation of campus SNS as a social behavior and evaluate the impact made by social factors such as subjective norms and identity, as well as the impact of perceived reality and playfulness through an extended technology acceptance model.

전자상거래는 21세기를 이끌 새로운 경제 패러다임이라고들 한다. 기업들은 새로운 경영환경에 뒤쳐지지 않기 위하여 적극적으로 전자상거래를 도입하고 있는 상황이다. 그러나 기존 오프라인을 온라인화 하는 단순한 비즈니스 모델보다는 인터넷의 확장, 개방성을 치대한 활용하는 모델이 전자 상거래에 더욱 적합한 모델이 될 것이다. 이에 본 연구는 단순히 상품정보를 고객에게 제공하여 상품 구매를 바라는 수동적 운영에서 보다 적극적으로 고객과 함께 기획하고, 상품의 진열과 판매의 운영 전반에 대한 고객 참여를 유도하는 비즈니스 모델이라 할 수 있다

This study was designed to find what impacts store attributes and personal characteristics have had on customer loyalty to beauty shops. Participants were 283 men and women who had experienced services in beauty shops and selected from the Metropolitan area, Busan, Gyeongbuk area, Gyeongnam area, Chungcheong area, and other area. In conclusion, technical factor and lifestyle have had the greatest impact on customer loyalty to beauty shops. In beauty market faced with keen competition, the way to meet customers' needs is to run a distinguished beauty shop with distinct beauty techniques in consideration of individual lifestyle. This will help raise customer loyalty to beauty shops. This study has the important implication that personal characteristics as well as store attributes has been proved to be essential for increasing customer loyalty to beauty shops. I hope that future studies will continue to examine different marketing factors by different beauty shops, with additional analysis on the details, contributing to make a marketing strategy available for beauty shop owners.

Most previous electronic commerce studies have focused on a single product or similar products. The effects of different product types have been relatively neglected. and so previous studies have limited the generalization. The purpose of this study was to explore the effects of different product types. The Internet product and service classification grid proposed by Peterson et al.(1997). A survey-based approach was employed to investigate the research questions. Regression analysis demonstrated that the determinants of online shopping acceptance differ among product or service types. As a result of analysis, personal innovativeness of information technology, perceived Web security, personal privacy concerns, and product involvement can influence consumer acceptance of online shopping, but their influence varies according to product or service types.

Recently, spread of Smartphones caused activation of mobile services, because of that Big Data such as clouding service able to proceed with large amount of data which are hard to collect, save, search and analyze. Many companies collected variety of private and personal information without users' agreement for their business strategy and marketing. This situation raised social issues. As companies use Big Data, numbers of damage cases are growing. In this Thesis, when Big Data process, methods of analyze and research of data are very important. This thesis will suggest that choices of security levels and algorithms are important for security of private informations. To use Big Data, it has to encrypt the personal data to emphasize the importance of security level and selection of algorithm. Thesis will also suggest that research of utilization of Big Data and protection of private informations and making guidelines for users are require for security of private information and activation of Big Data industries.

This study attempts to examine the acceptance factors of mSFA systems based on the innovation diffusion and technology acceptance model, and to measure the performance effects of mSFA systems using BSC metrics. Results show that (1) the characteristics of mobility and interactivity have positive impacts on perceived usefulness, ease of use, and professional fit. But the characteristics of personal identity were not perceived as useful due to users' negative feelings about privacy infringement and surveillance. (2) Job fit has positive impacts on perceived usefulness and professional fit. (3) Perceived usefulness, ease of use, and professional fit positively influence the degree of users' dependence on mSFA systems, which have positive impacts on users' performance measured by the personal BSC metrics including perspectives of finance, customer, internal process, and learning and growth.
