Early morning delivery possesses distinct characteristics that differentiate it from standard delivery services. This service typically involves delivering products to customers during the early morning hours, primarily before 7 AM. While online early morning delivery offers various advantages from a customer perspective, it also presents challenges that sellers and online shopping companies need to overcome. The early morning delivery market is experiencing significant growth in the online food retail sector, incorporating both PC-based online shopping and mobile shopping. The objective of this research is to identify the factors influencing customer satisfaction and the intention to reuse in the context of early morning delivery for online shopping. To model the online shopping environment with early morning delivery, independent factors were categorized into three types: System Properties, Product Characteristics, and Delivery Characteristics. This study examined the relationships among these three independent factors, the mediating factor of customer satisfaction, and the dependent variable of the intention to reuse. To conduct this research, empirical validation of the research hypotheses was carried out using the final dataset for analysis. Within this study, the previously explored System Properties, Product Characteristics, and Delivery Characteristics were established. Summarizing the findings of the analysis, it was discovered that System Properties and Product Characteristics played a significant role in determining the quality of early morning delivery services for online shopping. While product diversity and convenience had a positive impact, it is noteworthy that Delivery Characteristics did not influence customer satisfaction. Consequently, it can be concluded that there is no effect on the intention to reuse.

최근 WEB 2.0 환경을 통해 사용자는 직접 응용 프로그램과 데이터를 이용하여 새로운 컨텐츠를 생산하는 주체로 변모하고 있다. 이러한 사용자의 자발적이고 적극적인 참여는 'UCC(사용자 제작 컨텐츠)'라고 불리는 새로운 문화 컨텐츠의 활성화로 이어지고 있다. 특히 글과 그림, 소리 등이 총체적으로 엮여 있는 동영상 UCC 의 경우, 이야기 구조나 캐릭터가 갖는 내용적인 특성과 제작자의 제작 취지를 훼손없이 살릴 수 있다는 제작의 특성으로 인해 WEB 2.0 환경에서 사용자의 참여가 더욱 두드러지고 있다. 본 연구에서 '사용자들이 열광하는 동영상 UCC 는 어떤 특징을 갖는가?' 라는 질문에 답하기 위해 동영상을 시청하는 사용자의 몰입과 창의성 평가를 진행하였고 이에 영향을 주는 요인으로 동영상 UCC 를 구성하는 내용적인 특성인 이야기의 내러티브와 캐릭터의 과장성을 살펴 보았다. 그리고 이 요인들의 상호작용에 영향을 주는 매개변인으로 제작자의 제작의도에 따른 컨텐츠의 특성을 선정하였다. 제작자의 의도에 따른 컨텐츠의 특성을 분류하기 위해 라캉의 주체이론과 퍼스의 기호학 이론을 바탕으로 모형을 제안하였으며 이를 검증하기 위해 UCC 사용자들을 대상으로 현재 서비스 중인 동영상 UCC 를 보여주고 설문을 실시하였다. 연구결과 제안하는 모형의 적용가능성이 입증되었으며 제작자의 의도에 따른 컨텐츠의 특성에 따라 이야기의 내러티브나 캐릭터의 과장성이 사용자의 몰입과 창의성평가에 미치는 영향력이 다르게 나타나는 것을 확인할 수 있었다.

This work is intended to investigate how the factors of enterprise mobile SNS affect user satisfaction and continuous use intention through technology acceptance model proposed by Davis. To achieve the purpose, this researcher explored Information Systems Success model proposed by DeLone & McLean, Technology Acceptance Model proposed by Davis, and Model after Acceptance, and on the basis of the investigation, performed a study. For the data of this work, 9 enterprises, each of which has more than 100 employees and is located in Seoul, were chosen, and a questionnaire survey was conducted on their 276 employees who experienced enterprise mobile SNS. As a data collection tool, a structured self-administered questionnaire was used. For data analysis, SPSS 18.0 and AMOS 18.0 were used for applying Structural Equation modelling. According to the results of this work, three factors of enterprise mobile SNS-systematic factor (system quality, information quality, and service quality), user factor (personal innovation and personal familiarity), social factor (social effects and social interaction)-affected user satisfaction and continuous use intention through perceived availability, perceived easiness, and perceived enjoyment. Also, it was found that the direction of effects matched a theoretical prediction. And, it was revealed that the decision variables and mediating variables significantly affected user satisfaction and continuous use intention. Theoretical and practical meanings were discussed for the study result, and some suggestions were made for the issues of this work and future studies.

CORBA is a middleware which enables distributed objects to cooperate regardless of specific platforms and techniques. But the ordinary CORBA communication model does not support multi-cast, and needs delay time, because it synchronously connects the distributed objects between client and server. To solve these problems, OMG suggests CORBA Event Service which can provide multi-cast among application objects. This paper presents a new technique for improving reliability, and supporting two-way communication by laying two interface objects on each consumers and suppliers that are registered in event channel. Also, to integrate objects efficiently, we, group distributed event channels and management it as view, A coordinator selected from channel group controls group and view.
