Recently, there are two important research trends in the literature the red-time collaborative computing end electronic business process automation. This paper is one of those efforts that would establish an effective business office working and computing environment hough the integration of those two cutting-edge technologies. That is, we try to develop a workflow modeling tool that is semantically based upon the information control net(ICN), which is a typical workflow model for specifying office work procedures(business processes), and that is systemically based upon the real-time collaborative operations by a set of actors, which is called group, We name it "group ICN editor". This paper describes the design and implementation of the group ICN editor that is operable under the real-time collaborative computing environment. We use the Flexible rJAMM toolkit that enables the ICN editor to operate among multiple actors(group) through the event-driven collaboration platform, Consequently, a set of workflow and business processes defined through this editor is not only stored onto database but also transformed into the format of the workflow process definition language(WPDL) that is a standardized workflow description and specification language proposed by the workflow management coalition(WfMC).ion(WfMC).

In the focusing on the important of wireless internet, mobile terminal device plays a central role in tracking and coordinating terms in mobile business processing. Especially, mobile device has been considered as a key technology for embedded software and ubiquitous era. Because existing web environments is moving to wireless internet, the new concepts for wireless internet computing environments has gained increasing interest. Mobile agents provide a new abstraction for deploying over the existing infrastructures. Mobile application systems require the flexibility, adaptability, extensibility, and autonomous. New software developments methodology is required to meet the requirements. In this paper, we present an agent architectures model that allows compassable components with pluggable and independable. Our approach involves wrapping components inside a servlet. We have used the model and components to develop the PDA mobile agent.

Web services are being recognized as the efficient way to integrate the distributed applications on the web based on the web standards such as SOAP, WSDL and UDDI. Recently, BPEL4WS is suggested as a standard integration model language for web services to integrate them efficiently. The recent studies of web service integration are focused on the comparability among the services, process identification and tracing, and automation, However, little or no effort has been dedicated to the reusability, extensibility on the business process integrated services and how to allocate the services dynamically, So, in this paper, we propose how to increase the reusability and extensibility of integrated structure when services are integrated using BPEL4WS, and how to allocate and use the services dynamically. Also, we propose the framework of the composition of web services for the efficient use of suggested integrated structure.

In this paper, we propose an efficient network virtualization model in cloud computing environments. Virtualization is a key technology for the implementation of service-oriented architecture. It is a standardized framework that can be reused or integrated with changing business priorities through a IT infrastructure. Network virtualization has emerged as an important technical issues of the future virtualization technology in Internet. The concept of network virtualization and related technologies stay in ambiguous status since network virtualization is in its early stage. Thus, we propose a network virtualization model for cloud environment by analyzing the existing network virtualization technologies.

Life log started with the simple purpose of recording or sharing mainly data regarding one's personal life, but with the introduction of advanced specialized analytic methods by many corporations, a new type of business based on the life log recently emerged, with an aim of improving the quality of people's personal lives. In spite of the indispensable advantages, however, personal health lifelog service brings critical challenges that cannot be avoided from user side if the security of the data is concerned. The problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the revitalization of personal health lifelog services. In this paper, we propose an information security reference model for the personal health lifelog services. Our proposal can contribute to increase the related industry to cultivate new market by suggesting the clear announcement of the guidelines using privacy protection reference model for user-specific healthcare services which uses personal lifelog.

Parcel service is to deliver goods from one place to the designated destination requested according to user request. Parcel operations such as sorting, distributing, etc. or the managed information are heterogeneous by the companies. Additionally, it is impossible to support interoperability between companies with unformatted data of manual processing. Most parcel package boxes attached to paper typed waybill is attached is delivered to consignee. So, security problems such as personal information leaking are occurred, or extra processing time and logistics costs are needed due to wrong or the damaged information. Business environment of parcel service is rapidly changed as introducing unmanned delivery or the advanced technology such as Internet of Things. User want to know the accurate status or steps from parcel service request to delivery. To provide these requirements, the unified and integrated waybill information for reliable transportation of parcel service is needed. This information will provide to pickup or delivery carrier, warehouse or terminal, and parcel service user per pickup, transport, and delivery stage of parcel delivery service. Therefore, this paper defines the simplified and unified information model for parcel service waybill by analyzing information systems used for logistics unit processes that is occurred to parcel service, and manual work processes, and developing the relevant information of work flows occurred between business processes or transactions with the collected or processed information by from parcel service's stages. It is possible to share these standard model between business entities, and replacing paper typed waybill will improve national life safety as preventing security threats by paper typed waybill. As a result, it will promote the public interest from the stakeholder's perspective.

인터넷 사용자들의 증가와 여러 기기들의 발달에 따라 인터넷 사용자들은 새로운 형태의 커뮤니케이션을 스스로 발전시킬 수 있었고, 이러한 흐름이 최근 UCC의 폭발적인 증가로 이어졌다. 하지만 최근까지 사용자들이 왜 자신이 스스로 노력을 들여서 UCC를 공유하는 지에 대한 명확한 설명은 부재한 상황이다. UCC공유동기는 기존에 지속적으로 연구되어 왔던 가상커뮤니티나 온라인구전활동의 참여동기를 상당부분 가지고 있으나 이들로 설명할 수 없는 새로운 참여동기를 포함하고 있는 것으로 보여진다. 본 연구에서는 이러한 UCC 공유 동기를 파악하기 위해 UCC 공유 경험이 있는 사람들을 대상으로 설문을 수행하였고, 요인분석을 통해 UCC공유동기가 '자가 창조의 즐거움', '커뮤니티에 대한 책임감', '자아표현 욕구', '타인과의 교제', '보상'의 동기로 요인화될 수 있음을 밝혀냈다. 그리고 이들 동기가 UCC 공유 의도에 어떤 영향을 주는지를 알아보았다. UCC공유의도를 양적인 측면과 질적인 측면으로 나누어, 앞에서 요인화 된 5가지 UCC동기가 각각에 어떤 영향을 주는지를 확인하였다. 본 연구의 결과를 통해 UCC를 공유하는 사용자들을 좀 더 이해할 수 있을 것이고, UCC를 비즈니스모델로 하는 온라인기업들에게 UCC참여 및 양질의 서비스를 제공할 수 있는 가이드를 제시할 수 있을 것이다.

Incorporating proprietary existing it solutions like legacy systems or vendor specific with new technologies is an expensive and time consuming task. Such situations take place due to the lack of ability of proprietary software to cooperate with other parties or to cooperation only with specific vendor products. Such a situation is undesirable and causes a prolonged adaptation period for new applications. This thesis is to show the new approach to creation of Internet applications in Service Oriented Architecture through loose coupling, introduces fare more flexibility into a system composed of connected applications. This approach allows one to integrate through XML based Web Service and reuse a number of arbitrary services available over the Internet in a complex processes specified as a workflow model.

With the development and invention of computer and internet, GIS (Geographic Information System) has provided diverse services to users. Web 2.0, the next generation web, has been developed to create a new business by accumulating and structuring information from many users. The characteristics of Web 2.0 are blog, longtail distribution, SNS, DCC, collective intelligence, and so on. This study proposes a GIS 2.0 service model to maximize the introduction effect and use of GIS by the method that two-way communication and the participation of consumer, characteristics of Web 2.0, are used to build more practical GIS rather than providing spatial information in one-way and simple inquiry oriented way.
