In the recent Internet environment, there are different competition patterns among competitors as it was before. As we see real world example such as Covisint in automobile industry and Exostar in aerospace industry, collaboration among competitors now takes place and industry-wide B2B marketplaces come into existence. Hence, we suggest the extended system dynamics simulation model based on Kim(2002)’s collaboration profit models in order to explain competitors’ collaboration in the e-business environment. After all, we investigate the necessity of collaboration between competitors, and show the presence of the optimal investment decision making to collaborate. We also show that the effect of collaboration is changed as varying the industry characteristics such as standardization and volatility.

Since customer's demand is various and product life cycle is getting shorter, many manufacturing company is trying to reduce product development time and cost. For that reason they make an effort to design product on collaborative environment. The various activities in a product development are highly distributed. This distributed nature of the activities implies that teams will be working indifferent place and technical environments. Thus at a given time, teams might work on he same product from different perspectives. This will require efficient communication amongst the various individuals and the various softwaretools that are used by them. Therefore, there is a need for a computerized frame work that can support distributed design such that participants from different backgrounds collaborate towards one common goal. This paper presents the architecture of a collaborative design system. It then reports on the study of computerized frame work focused on collaboration for product development.

본 논문에서는 지역적으로 분산되어 있는 사람들간에 공동작업을 가능하게 하는 어플리케이션 공유 공동작업 엔진(ACE:Application sharing collaboration Engine)을 설계하고 구현하였다. 어플리케이션 공유는 한명 또는 그 이상의 사용자들이 개인 컴퓨터 시스템 상에서 실행되고 있는 전용 어플리케이션을 다른 사용자들과 함께 공유하도록 하는 기술이다. 우리는 실시간 어플리케이션 공유가 가능하도록 ASO(Application Sharing Object)객체와 그 행위들을 정의하였고, 공동작업 엔진은 ASO 객체들을 이용하여 분산된 시스템간에 공유기능을 처리한다. ASO 객체는 활성화 객체(activateASO), 수정 객체(updateASO), 입력 객체(inputASO) 그리고 제어 객체(controlASO)들로 구성되어 있다. ASO 행위는 키보드 입력과 마우스 클릭과 같은 특정 순간에 발생되는 이벤트와 뷰 이미지 같은 어떤 순간에 유지될 수 있는 상태들의 변화에 의하여 발생 된다. 구현된 어플리케이션 공유 공동작업 엔진은 데이터 회의 시스템, 원격 교육, 그리고 엔지니어를 위한 프로젝트 공동작업 등에 적용될 수 있다.

In order to keep and increase a competitive potential, industrial enterprises have to reduce their costs for product development as well as shorten lead time in product development processes. Moreover they have to respond to market factors and conditions such as increasing demands for functionality and individuality of products, short product life cycles, high pressure on prices and time to market. The improved functional requirement in connection with high time and cost pressure lead to high risk in product development. Technological fine improvements in connection with high time and cost pressure lead to high development risk. To cope with these challenges many enterprises have to collaborate globally. The collaborative engineering in product development is aimed to create distributed collaborative corporations and to facilitate the management of design conflicts. This paper provides a methodology for analyzing collaborative design process as well as the tools and the framework to support collaborative product development. The methodology can identify the interdependences among design tasks and teams. The tools and framework are implemented to facilitate the management of product development process.

In spite of the rapid growth of mobile multimedia contents market, most of the customers experience inconvenience, lengthy search processes and frustration in searching for the specific multimedia contents they want. These difficulties are attributable to the current mobile Internet service method based on inefficient sequential search. To overcome these difficulties, this paper proposes a MOBIIe COntents Recommender System for Movie(MOBICORS-Movie), which is designed to reduce customers' search efforts in finding desired movies on the mobile Internet. MOBICORS-Movie consists of three agents: CF(Collaborative Filtering), CBIR(Content-Based Information Retrieval) and RF(Relevance Feedback). These agents collaborate each other to support a customer in finding a desired movie by generating personalized recommendations of movies. To verify the performance of MOBICORS-Movie, the simulation-based experiments were conducted. The results from this experiments show that MOBICORS-Movie significantly reduces the customer's search effort and can be a realistic solution for movie recommendation in the mobile Internet environment.

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.

Purpose - The purpose of this study is to examine how a broad palette of government support measures and firms' membership in government-developed clusters are related to firms' openness in innovation processes. Design/methodology/approach - Empirically, this study analyzes the Korea Innovation Survey 2018 data on the innovation activities of 1,450 Korean R&D-active manufacturing firms in a three-year period from 2015 through 2017. Findings - The results suggest that firms engage in open innovation to a greater extent--as measured by the breadth of external collaborating partners and of the utilized external sources of knowledge--when they are provided with a broader palette of government support measures and are located in government-developed clusters. However, the effect of diverse government support measures is attenuated for firms located in these clusters. Research implications or Originality - This study contributes to the innovation literature by illuminating how firms' open innovation can be understood in a national innovation system. Moreover, it provides valuable implications for firms seeking to obtain government support and collaborate with others.
