The drone has the restrictions on the controls, the battery and the surrounding environment in performing missions such as fire extinguishing. This restriction can improve the limitations that leave the leader can be monitored. The existing method of constructing the leader based on the GPS is highly dependent on the signal and is vulnerable to hardware defects. In this paper, we solve these problems with dynamic leaders decision. Drones can use their leader drones rather than remote controls. Information about the drones changes depending on the surrounding environment by replacing the leader with a dead battery or electing leader by the drones themselves without human intervention. This suggests that the leader monitors the community through a framework for continuing the drones collaboration and that the community can collaborate to overcome the limitations and continue the mission. The analysis of the proposed system through simulation experiments confirm that it has a better task performance. By using this system, it is possible to continue the mission and solve problems that are vulnerable to hardware defects.

Today many corporations converge clients' needs and IT technology, and then they are developing new service model in order to survive global situation. The changes of manufacturing industry from simple manufacture to industry for focus on services is getting speeded up, because not only growth of service part but also enlargement in creating value in services is expected. And services through collaboration with knowledge based service and only manufacturing industry is important. In this situation, this thesis is willing to propose methodology for Inter-Industry Collaboration Service Model. The proposed methodology includes procedures which develops service model, plans for Inter-Industry Collaboration Service Model and evaluating framework. Also, this applied case studies. I look forward to offering useful guideline on the proposed methodology in this study to corporations that try to create new service model through Inter-Industry Collaboration Service Model.

로봇 어플리케이션의 활용도는 사회 전반에서 점차 확대되고 있지만 로봇들의 컴퓨팅 자원 차이로 인해 한 로봇에서 다양한 어플리케이션을 실행하기는 힘든 실정이다. 본 논문에서는 로봇이 주변 장치와의 자원 공유를 통해 자원의 제약을 극복하는 프레임워크를 제안한다. 프레임워크는 협업에 요구되는 공통 구성 요소들을 정의하고 어플리케이션을 쉽게 제작할 수 있는 API를 제공한다. 로봇과 다른 장치가 네트워크로 연결된 환경에서 동작하는 로봇을 이용한 체조 학습 어플리케이션의 예시를 통해 프레임워크의 동작 흐름을 보인다.

최근 설계 협업 시스템의 점차 발전됨과 함께, BIM 기반의 정보교환이 차세대 건설 프로젝트의 성공적 수행에 주요 요소로써 작용하고 있다. BIM 협업 중 발생하는 데이터 호환 문제에 대한 해결책을 제시하고 있는 많은 연구들이 수행되고 있지만, 여전히 다양한 BIM 저작도구로부터 생산되는 BIM 데이터의 교환은 디자인과 엔지니어링 분석 단계에서 발생하고 있다. 그리하여 본 논문은 현업 설계 프로세스 내에서 발생하는 데이터 정보 교환에 대한 문제점의 발생 원인을 분석하고 BIM 기반의 설계 협업 환경의 개선을 위한 BIM 정보 교환 프레임워크를 제안하였다. Open-BIM 기반의 정보 교환 환경의 정착을 저해하는 요소를 발견하기 위해서는 현재와 앞으로 수행될 BIM 기반 설계 협업 프로세스 환경변화에 대한 분석이 우선적으로 수행되어야 한다. 협업 설계 프로세스 내 원활한 정보 교환의 저해 요인 분석을 통해 본 연구는 Open-API와 IFC기반의 BIM 협업 지원 시스템을 제안한다. BIM 무결성 피드백 시스템이라 명명된 API 솔루션은 IFC 기반의 데이터 교환에서 발생하는 상호 불일치성을 판별하고 report를 작성해 주는 기능을 수행한다. 또한, 본 연구는 IFC기반의 정보 교환 프레임워크 시스템을 제안하였으며, 앞서 언급한 API를 탑재하고 있으며 BCF 플러그 인을 지원하는 시스템을 통해 BIM 설계 협업 단계 내에서 정보 교환의 유연성을 도모하고 있다.

Recently, there have been discussions among national observatories in East Asia about the possibility of EAO and the Subaru observatory forming a partnership. The official EAO-Subaru partnership can make the powerful wide-field observation capabilities of Subaru available to Korean astronomers through EAO, and also can serve as an excellent platform to gather astronomers in East Asia together for flourishing regional collaboration activities. A working group has been formed to outline the framework of the EAO-Subaru partnership, and the working group report has been prepared. In this talk, I will explain the proposed partnership framework in the working group report. Inputs are very welcome from KAS members about the proposed framework.

Purpose - Due to its potential to improve supply chain operations, supply chain collaboration has attracted significant attention from both academics and practitioners. This study focuses on VMI, in collaboration with consignment, and examines its impact on supply chain performance. Research design, data, and methodology - This study employs the analysis of mathematical models, formulated based on the proposed supply chain framework. Using numerical examples, it evaluates the performance of three supply chain systems: one including VMI and consignment, a consignment-only system, and a traditional system. Results - The combination of VMI and consignment produces greater supply chain benefits than the consignment-only and traditional systems. Whereas only the performance of the buyer improves with the consignment-only system, the system with VMI and consignment is beneficial to both the buyer and supplier. Conclusions - The results of this study reveal that the inclusion of the additional collaborative function of VMI makes consignment a better supply chain collaboration program. Future studies should examine issues regarding the testing of diverse collaboration programs and the building of a firm theoretical background.

Various personalized services are provided based on user context these days, and IoT(Internet of Things) devices provides effective ways to collect user context. For example, user's activity such as walking steps, calories, and sleeping hours can be collected using smart activity tracker. Smart scale can sense change of user's weight or body fat percentage. However, these services are independent to each other and not easy to make them collaborate. Many standard bodies are working on the documents for this issue, but due to diversity of IoT use case scenarios, it seems that multiple IoT technologies co-exist for the time being. This paper propose a framework to collaborate heterogeneous IoT services. The proposed framework provides methods to build application for heterogeneous IoT devices and user context management in more intuitive way using HTTP. To improve compatibility and usability, gathered user contexts are based on MPEG-UD. Implementation of framework and service with real-world devices are also presented.

Due to the development of information technology, Convergence and Creative Economy became hot issues. For example, products become more intelligent and services are likely to be connected and integrated around core services or provided as bundle solution. Meanwhile products and services are integrated in the context of mutual supplementation, which leads to Servitization of Products and Productization of Services in many industries. Previous studies have addressed Convergence with different terms and definitions such as Convergent, Multicategory Multifunctional Product, Clouding Service, Bundle and so on from one perspective such as consumers, suppliers or technology according to a wide range of academic approaches. Thus, this study attempted to suggest the most typical convergence products released in the convergence environment and categorize those products. Furthermore, this study has pointed out the problems in the New Product Development Framework discussed in the studies on marketing by taking the situation of the public sector into account and then suggested "New Service Development Framework in the Public Sector" that are different from traditional e-Gov. approach basically and will enable the government to create public information service and provide them to enterprises or citizens. It also emphasized the importance of Business Conceptualization Stage in the framework; argued that there is a necessity of an integrative study from the perspective of technology on the basis of the approach from the perspective of marketing and Policy such as a study of consumer behaviors, design and marketing channel and Policy Integration for the development and dissipation; and furthermore suggested the cases-the development/Diffusion of Transportation Card Service in Seoul and CFC (Call for Collaboration) in Singapore-in order to verify the framework. There is a need to supplement New Service Development Framework so it is able to reflect the distinct characteristics of the public sector from the academic perspective and be used as practical guidelines for SI (System Integration) business to shift into IT Service business. Last but not the least, this study has suggested the limitations and the directions for the future studies.
