In terms of B2B, business partners require works that define 1h13ir ability to operate business collaboration. The document outlining collaboration is the basis of improving the system of business partner and its interoperability. In addition, the definition of business interaction that is based on the documents demonstrating inter-cooperation of business companies is needed to function interoperability properly, and business trading is performed depending on the documents that define reciprocal action of collaboration. In ebXML, CPP(Collaboration-Protocol Profile) defines one business partner's technical capabilities to engage in electronic business collaborations with other partners by exchanging electronic messages. A CPA(Collaboration-Protocol Agreement) documents the technical agreement between two partners to engage in electronic business collaboration. In this paper, I draw up a plan for a composer system that deals with business collaboration document to ameliorate the interoperability of B2B companies.

This paper proposes the distance-video-guarding system technology based on collaboration CBM personal computer which enables additional functions such as monitoring each room while the guarding is in progress. This system sends the atmosphere of guarding by checking the status of environment with the sensor using ISDN. Current remote guarding desktop system uses leased lines (T1/E1 ) applying fast speed rate and security. This system provides an external monitoring system which runs on ISDN Public line also. Monitoring system transfers the natural status of each site to center controller of the guarding system.

Companies have made an investment of cost and time to optimize processing of a new business model in a cloud environment, applying collaboration technology utilizing business processes in a social network. The collaborative processing method changed from traditional BPM to the cloud and a mobile cloud environment. We proposed a collaborative system for operating processes in social networks using MOXMDR-DAI+ (eXtended Metadata Registry-Data Access & Integration based multimedia ontology). The system operating cloud-based collaborative processes in application of MOXMDR-DAI+, which was suitable for data interoperation. MOXMDR-DAI+ applied to this system was an agent effectively supporting access and integration between multimedia content metadata schema and instance, which were necessary for data interoperation, of individual local system in the cloud environment, operating collaborative processes in the social network. In operating the social network-based collaborative processes, there occurred heterogeneousness such as schema structure and semantic collision due to queries in the processes and unit conversion between instances. It aimed to solve the occurrence of heterogeneousness in the process of metadata mapping using MOXMDR-DAI+ in the system. The system proposed in this study can visualize business processes. And it makes it easier to operate the collaboration process through mobile support. Real-time status monitoring of the operation process is possible through the dashboard, and it is possible to perform a collaborative process through expert search using a community in a social network environment.

본 논문은 열린대학(및 열린병원) 구현을 위한 캠퍼스내(종합병원내)에서의 무선 LAN을 이용한 멀티미디어 원격교육(및 원격진료) 시스템 구현에 관한 연구이다. 본 시스템은 정보통신 기술과 멀티미디어 기술이 접목되어 개발된 시스템이다. 또한 본 시스템은 성균관대학교의 원격교육시스템을 확장한 개념이기도 하다. 또한 본 원격교육 시스템은 멀티미디어 미들웨어에 의해 실시간 상호참여형 환경과 IP multicasting을 제공하고 있다.본 시스템은 캠퍼스 내에서 AP(Access Point)을 사용한 무선 LAN과 캠퍼스와 캠퍼스 사이의 T1/E1 네트워크로 구성되어 있다. 이것은 로밍지역을 해결하기 위한 handoff와 중재를 위한 다중 브릿지을 사용함으로써 구현이 가능하다. Abstract In this paper, we propose a multimedia distance education system(or telemedicine) using a wireless LAN for an inner campus university/hospital, which is intended to implement an open university. This system is implemented by a high technology of multimedia and information communication software. Also, this system is an enhanced and expanded system of the conventional distance education of SKKU(Sung Kyun Kwan University). The structure of this system consists of a T1/E1 network(information super high way) between campuses and wireless LAN using the AP(Access Pointer) inner campus. It will be able to use a use multiple bridge for mediation and hand off to solve roaming areas. This distance education system supports a real-time collaboration environment and IP multicasting by multimedia middleware for collaboration.

This paper explains a performance analysis of an error detection system running on nested session management of cloud computing collaboration environment using rule-based DEVS modeling and simulation techniques. In DEVS, a system has a time base, inputs, states, outputs, and functions. This paper explains the design and implementation of the FDA(Fault Detection Agent). FDA is a system that is suitable for detecting software error for multimedia remote control based on nested session management of cloud computing collaboration environment.

This paper explains a system that is suitable for detecting software error for multimedia distance education based on home network environment. This system consists of an ED, and ES. ED is an agent that detects an error by hooking techniques for multimedia distance education based on home network environment. ES is an agent that is an error sharing system for multimedia distance education based on home network environment. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participants engaged in a cooperative work.

In this paper, we discuss a model for increasing reliability of data through N screen server and client model environment. Our Digital Carousel enables user to share media objects through media synchronization mechanism. We suggest the Digital Carousel system based on CoAP(Constrained Application Protocol) for N-Screen so that the users participated in collaborative work may refer shared media objects as the same view to others. With this sharing system, a group cooperating users can share applications data. This paper explained a performance analysis of a system with function comparison running on multimedia collaboration work based on CoAP and N screen techniques.

This paper explains the design and implementation of the ESA(Error Sharing Agent). ESA is a system that is suitable for detecting, sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). This system consists of an ED, ES, and ER. ED detects an error by hooking techniques. ES is an agent which is an error sharing system for distributed multimedia collaboration environment With error sharing system, a group cooperating users can share error applications. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participants engaged in a cooperative work. We propose how an error application can be treated as 'media' in a multimedia collaborative environment.
