Recently, various location-based services are becoming very popular in mobile environments. In this paper, we propose a new concept of a frequent item set, called “associative class set”, for supporting the location-based service which uses a large quantity of a spatial database in mobile computing environments, and then present a new method for efficiently generating the associative class set. The associative class set is generated with considering the temporal relation of queries, the spatial distance of required objects, and access patterns of users. The result of our research can play a fundamental role in efficiently supporting location-based services and in overcoming the limitation of mobile environments. The associative class set can be applied by a recommendation system of a geographic information system in mobile computing environments, mobile advertisement, city development planning, and client cache police of mobile users.

This study empirically analyzed the influence of communication and social support on the organizational immersion of salespeople in cosmetic brand shops in Seoul. Communication and social support were set as independent variables as factors affecting organizational immersion. Communication variables were subordinate variables such as formal communication, communication with supervisor, and communication with colleagues. Sub-variables of social support factors were set as support of superiors and support of colleagues. As a result of the analysis, communication factors such as formal communication, communication with supervisor, communication with colleagues were analyzed as the significant influencing factors on the organizational immersion of workers. The support of supervisor was analyzed as the significant factors influencing the organizational immersion of workers. However, support of colleagues was analyzed as a factor that did not affect the organizational immersion of workers.

Objective: The purpose of this study was to explore the feasibility to utilize image data recorded and accumulated from CCTV at child care centers. Methods: Literature reviews, consultations and workshops with scholars studying child development, legal professionals, and engineers, focus group interviews with professionals working with young children, and surveys targeting parents, directors and teachers were implemented. Results: It was found the big data from CCTV at child care centers can be used to make policies and implement research as a secondary data set after anonymization. Extracting implicit and useful data from images stored on CCTV is technically feasible. Also, it can be legally guaranteed to analyze the data under the condition of acquiring informed consents. Conclusion/Implications: It was likely to utilize image data from CCTV at child care centers as a secondary data set in order for policy development and scholarly purposes, after overcoming obstacles of the budget for additional infrastructures and consents of information holders.

SET은 인터넷과 같은 개방형 통신망에서 안전하고 효율적인 신용카드 기반의 전자 결제를 수행하기 위해 개발된 전자 지불 표준 프로토콜이다. SET을 기반으로하는 전자 지불 시스템은 크게 카드를 소지하고 있는 고객(Cardholder), 상품을 판매하고 대금 결제를 요구하는 상인(Merchant)기존의 은행과 연동하기위한 지불 게이트웨이(Payment gateway)로 구성되며 부가적인 요소로 인증기관(CA)을 포함하고 있다. SET은 고객과 상인, 상인과 은행간의 안전한 거래를 지원하기 위해 여러 가지의 강력한 암호화 알고리즘을 채용하고 있으며 이러한 SET의 보안성은 전자 상거래의 보급에 커다란 기여를 할 것으로 예상된다. 본 논문에서는 기존의 전자 지불 방식을 특성별로 분류하여 그 기능과 구성에 대해 검토하고 SET에서 사용된 보안 기술과 SET을 기반으로 하는 전자지불 시스템의 기능과 특성을 검토·분석한다.

The early phase of design intrinsically contains multiple sources of uncertainty in describing design, and nevertheless the decision-making process at this phase exerts a critical effect upon drawing a successful design. This paper proposes a set-based design approach for multi-objective design problem under uncertainty. The proposed design approach consists of four design processes including set representation, set propagation, set modification, and set narrowing. This approach enables the flexible and robust design while incorporating designer's preference structure. In contrast to existing optimization techniques, this approach generates a ranged set of design solutions that satisfy changing sets of performance requirements.
