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.

Purpose: Focusing on the complex supply chain operations beyond the simple dyadic relationship, this study evaluates the performance of the revenue sharing contract in three stage supply chain system. Research design, data, and methodology: The optimization model is developed to describe the supply chain system where one manufacturer, one wholesaler, and one retailer exist and pursue the maximum level of their own profits. In the numerical examples of the proposed supply chain model, two types of the revenue sharing contract, pairwise and spanning methods, are tested and their performances are compared with the traditional system. Results: The numerical analysis reveals that both types of the revenue sharing contract outperform the traditional system. All supply chain members can achieve the improved profits only when they determine the proper combination of revenue share ratios and price discount rates. Conclusions: This study finds out that both pairwise and spanning revenue sharing contracts can make the positive outcome that is acceptable to all members in three stage supply chain system. When the proper contract content is agreed among the supply chain members, the revenue sharing contract has the potential to be the practically feasible collaboration program for the multiple stage supply chain system.

The smart farm for livestock, in which information and communication technology (ICT) is combined with livestock farm, is mostly based on the cloud computing paradigm. A cloud-based smart livestock farm has disadvantages such as increased response time, burden on cloud resource caused by the increased number of IoT sensors, traffic burden on the network, and lack of failure resilience mechanisms through collaboration with adjacent IoT devices. In this paper, with these problems in mind, we propose an IoT collaboration system based on edge computing. By using the relatively limited computing resources of the edge device to share the cloud's web server function, we aim to reduce the cloud's resources needed and improve response time to user requests. In addition, through the heartbeat-based failure recovery mechanism, IoT device failures were detected and appropriate measures were taken.

Some Research is actively being done on a web-based collaborative learning system. This is changes in educational paradigm in the knowledge information age. A web-based collaborative learning system for question making is to improve the effect of studying through positive interactions between colleagues and to motivate studying through group competitions. This system is designed to active and self-leading studying when a learner do collaborative learning for question making in group. This system can help initiate and active studying to learner through a course of collaborative learning for question making. It can be used to achieve collaborative learning in various ways.

The study acknowledges the need for classification systems in arts and cultural education. The study constructs a faceted classification system for this domain based on systematic methods. The study utilized iterative collaboration between domain experts and classification system developers. The classification system consists of 13 main facets and terms. The classification system has values to manage information resources effectively and efficiently. It is also beneficial for reducing cultural gaps in arts and cultural education as well as providing an information gateway for users.

Purpose The purpose of this study is to investigate the development process and the effectiveness of the EISS (epidemiological investigation support system), which prevents the spread of infectious diseases like a novel corona virus disease, COVID-19. Design/methodology/approach This study identified the existing epidemiological support system for MERS through prior research and studied the case of the development of a newly developed epidemiological support system based on cloud computing infrastructure for COVID-19 through inter-ministerial collaboration in 2020. Findings The outbreak of COVID-19 drove the Korean Government began the development of the EISS with private companies. This system played a significant role in flattening the spread of infection during several waves in which the number of confirmed cases increased rapidly in Korea, However, we need to be careful in handling confirmed patients' private data affecting their privacy.

CPFR (Collaborative Planning, Forecasting and Replenishment)은 기존의 공급망 개선에 관한 어플리케이션이 갖는 문제점인 정보의 부정확성, 시스템의 단절, 관련 기업 간 협력의 부족 등과 같은 여러 장해요소들을 극복하기 위한 목적으로 설계된 최신 비즈니스 모델로서, 이는 공급망의 총재고를 최소화하기 위해서 공급망의 모든 구성원들이 최종소비자의 실제 수요정보에 근거하여 계획(Planning), 예측(Forecasting), 그리고 보충(Replenishment)을 시스템 상에서 협력적으로 결정하는 것이다. 본 연구에서는 구성원들 간에 발생할 수 있는 예외적인 사항들을 CPFR시스템의 예측단계에서 판별하고, 그러한 예외 사항들을 역동적으로 다루기 위한 지식기반 협업 에이전트 시스템(Knowledge-Based Collaboration Agent System)을 제시한다. 또한 지능적 추론(Reasoning)과 학습(Learning)을 통해 구성원들에게 예외 사항에 대한 최적의 해결안을 제시함으로써 협업 시스템의 자동화를 구현한다.

인터넷의 발전으로 국경을 초월한 팀간의 국제적 협업도 기술적으로 가능하게 되었다. 그러나 공용어가 아닌 각자의 모국어를 사용하는 경우 인터넷과 자동기계번역 (Machine Translation)을 활용하여 협업이 가능하도록 하기 위하여는 아직도 해결되어야 말 문제가 많다. 특히 자동기계번역은 특정 언어 외의 다양산 언어들간의 번역에서는 아직도 의사소통이 원활하게 이루어지지 않는 수준이다. 본 연구는 상이산 문화적 배경을 가지고 서로 다른 모국어를 사용하는 팀 간의 협업이 현재의 기술 수준으로 어느 정도까지 가능한가 하는 것을, 자동기계번역과 인터넷을 기반으로 고안된 ICSS ([nterrultural Collaboration Support System)를 활용한 실험을 통하여, 시스템과 인간의 상호작용을 중심으로 고찰하고자 하였다.

Building Information Modeling (BIM) has the great possibility of transforming the AEC industry. BIM will require increased information exchange and mutual collaboration between all stakeholders. BIM implementation and such increased collaboration can affect legal issues and contract provisions. And some legal issues accompanying BIM Implementation will be raised while a large change also comes in responsibility and role between all stakeholders. However, current standard agreement system is based on fragmented agreement between the architect and the owner, and between the owner and the contractor. Another legal obstacles and considerations associated with BIM implementation will be arose from BlM technology and use of BIM. AEC professionals in Korea have long utilized the standard agreement forms as well and look forward complementation of current standard agreement for BlM implementation. Such complement direction for the standard agreement will be examined by investigating the legal issues and overview comparison between AlA E202 and ConsensusDOCS 301.
