오늘날 기업환경은 고객의 요구에 대응하여 적시에 효율적으로 상품과 서비스를 공급하고 전체비용의 대부분을 차지하는 물류와 재고비용을 줄여 기업의 이윤을 극대화하는 것으로 변화하고 있다. 예전에 기업위주의 시장형성에서 고객위주로 시장이 변화하고 있는 것이다. 이에 따라 기업은 고객의 요구에 능동적으로 대응하기 위하여 리드타임의 단축이 필수적인 요소가 되어가고 있다. 이러한 기업환경에 변화에 따른 대안으로 나온 것이 실시간 제조와 공급사슬망관리(Supply Chain Management : SCM)이다. 본 연구는 실시간 제조를 지원하기 위하여 제조업체와 협력사간의 물류에 있어 Goldratt의 Drunm-Buffer-Rope 스케줄링을 이용하여 물류창고라는 Buffer를 두어 협력사중 재고의 부족현상이 일어날 경우에는 공급체인상의 능력제약자원(Capacity Constraint Resource: CCR)을 찾아 능력제약자원이 되는 협력사에 대하여 생산을 독촉하고 물류창고에서는 부족재고에 대한 불출을 개시하여 재고의 완충을 도모하고자 한다. 제조업체와 협력사간의 정보를 실시간 감시시스템(Real-Time Monitoring System : RTMS)를 응용하여 웹상에서 공유하며, 실시간 거래가 가능토록하는 공급사슬망 구축에 관한 연구와 이를 프로그램 구현을 통해 실제적으로 시험해 보고자 한다.

협력 시스템은 분산 시스템 환경에서 호스트들이 네트워크를 통하여 상호 연결되어 있으며 다양한 사용자가 여러 자원들 공동으로 활용한다. 협력 시스템 발전 및 정보 보안의 중요성에 대한 인식 증가로 인하여, 개방형 분산 협력 시스템 환경에서도 정보 통신 시스템의 자원을 보호하기 위한 여러 가지의 보안 서비스에 대한 연구가 진행되고 있다. 하지만 기존의 일반적인 보안 서비스로는 협력 시스템에 특징과 구조에 맞는 서비스를 제공하기 어려운 점이 있다. 본 논문에서는 저자가 개발한 산업 디자인 협력 시스템에서의 보안 프레임워크를 제안한다. 제안된 프레임워크는 인증, 암호와 정잭, 접근제어, 보안 정보 관리의 네 가지로 구분하며 각각의 서비스가 상호 보완적으로 구성되어 있다. 또한, 특정 협력 시스템에 맞도록 구성되었지만 다른 협력 시스템에도 응용할 수 있도록 표준화를 따랐으며, 사용자의 요구에 따라 다른 비밀성과 투결성을 지원하기 위한 QoP(Quality of Protection) 서비스도 고려하여 설계하였다. 제안된 보안 프레임워크는 접근제어 요소를 협력 시스템의 구성에 맞도록 재구성하여 기존 정책의 단점인 복합적인 상황에서 확실한 보안을 할 수 있었으며 접근 정의에 따라 다른 알고리즘을 사용함으로 보안 프레임워크가 포함된 후에도 빠른 협력 작업이 가능했다. 또한 디자인 협력 시스템의 동시성 제어 정책을 기반으로 접근 제어 정책을 결정하였기 때문에 시스템 성능에 향상을 가지고 왔다.

In modern society, the amount of information has been significantly increased according to the development of Internet and IT convergence technology and that leads to develop information obtaining and searching technologies from lots of data. Although the system integration for medicare has been largely established and that accumulates large amounts of information, there is a lack of providing and supporting information for nursing activities using such established database. In particular, the judgement for the intervention of pains depends on the experience of individual nurses and that leads to make subjective decisions in usual. In this paper, a pain nursing supporting method that uses the existing medical data and performs collaborative filtering is proposed. The proposed collaborative filtering is a method that extracts some items, which represent a high relativeness level, based on similar preferences. A preference estimation method using a user based collaborative filtering method calculates user similarities through Pearson correlation coefficients in which a neighbor selection method is used based on the user preference.

Joint overseas expansion could contribute domestic large enterprises and small/medium-sized enterprises to expand overseas construction market by complementing each other's vulnerabilities and weaknesses. To invigorate it, not only does mutual effort between both parties matter, but also providing motivation such as institutional incentives and compensations are important for inducing large enterprises to voluntarily expand overseas construction with small/medium-sized enterprises. However, institutional systems exist only to promote win-win growth limited to domestic construction except for overseas construction. Therefore, the purpose of this study is to establish cooperation evaluation system between domestic large enterprises and small/medium-sized enterprises for invigorating joint overseas expansion by evaluating large enterprises cooperation efforts, and offering incentives to some enterprises gaining a good grade. The developed system could contribute to effectively promote win-win growth by providing institutional guidelines. In other words, The government could induce large enterprises cooperation efforts to some parts which small/medium-sized enterprises need, and large enterprises could selectively and intensively support insufficient cooperation part based on the evaluation result.

The purpose of this study is to verify the effects of team trust and cooperative behavior on the food-service employees' perceived service performance as well as the moderating effects of team competency and other department support in the relationship among the team trust, cooperative behavior, and service performance of food-service employees. We conducted a survey of 1,080 food-service employees working in 8 hotels and 4 food-service stores located in Seoul, Gyeonggi, Song-do, Gyeongju, and Busan, and 841 food-service employees were employed for statistical analysis except unreliable responses. As a result of a SEM (structural equation modeling) analysis to confirm hypotheses, it was found that team trust (leader trust and co-worker trust) had a positive effect on the cooperative behavior. In addition, the cooperative behavior had a positive influence on the food-service employees' perceived service performance. Also found was the moderating effect of other department support in the relationship between the cooperative behavior and food-service employees' perceived service performance. Based on the research findings, we discussed its academic and practical implications, and suggestions on the future research.

본 논문에서는 모바일 ad-hoc 무선 센서 네트워크[1]에서 안정된 경로의 설정 및 설정된 경로의 lifetime 을 효과적으로 지원하여 데이터 전송효율을 향상시키기 위한 협력 도움 라우팅 프로토콜(CARP: Cooperative_Aided Routing Protocol) 을 제안한다. 제안된 라우팅 프로토콜의 기본 아이디어 및 특징은 다음과 같다. 첫째, 소스노드와 목적지 노드 사이의 안정된 라우팅 경로의 설정이다. 본 연구에서는 모바일 노드들의 이동성 정보를 이용한 엔트로피 기반의 안정된 경로 설정방법을 제안 사용한다. 둘째, 협력도움 전송 방법이다[3][4][5]. 설정된 경로 위로 데이터 패킷을 전송 할 때 경로 lifetime과 SNR의 효과적인 지원으로 데이터 전송률을 증가시키기 위해 이웃 노드들로부터 협력 도움을 받는다. 셋째, 기존의 센서 네트워크는 주로 고정된 노드 환경에서 많은 연구가 되어 왔지만, 본 연구에서는 노드들의 이동성을 고려한 환경에서 연구가 이루어진다. 제안된 CARP 의 성능평가는 OPNET(Optimized Network Engineering Tool)을 사용하여 이루어졌으며 성능평가를 통하여 제안한 프로토콜은 안정된 경로의 설정 및 데이터 전송효율을 효과적으로 증가 시킬 수 있음을 알 수 있다.

In Korea construction project case, architectural construction project is curtailed production because information network process within multidisciplinary isn't smooth. Particularly, the construction is not insufficient about performance, cost and material, construction process, etc. in result various question arises because of design error in construction step. And various mistake is made because communication path within multidisciplinary isn't smooth in architectural design and design change process. Therefore The final object of this study is to propose the establishment method of decision support model for the cooperative design in order to provides improved design coordination and optimize the building system.

The study is to analyze the success strategies of the Cooperative Integrated Arts Activities in Seoul and to explore ways to implement it to the local public school. According to research, Cooperative Integrated Arts Activities fulfill the purpose of providing universal arts education by being implemented in the school curriculum. They are also characterized by active administrative and financial support and interactive participatory arts education with assured diversity. Therefore, when applying to a local public school, it is necessary to consider factors such as active administrative support, sustainable allocation of human and material resources, customized arts education that engages the all students and reflects their unique characteristics, social distribution through sharing, and continuous monitoring.

After M. Porter proposed the concept of industrial cluster, a lot of academic papers and industry surveys have suggested that industrial cluster is the key factor to competitive edge and long-term economic growth. Industrial cluster is often defined as geographical concentrations of interconnected entities in a particular industrial field. And the agglomeration economy is regarded the key factor of developing the industrial clusters. The industrial clusters often have been growing over the territory of local governments. Therefor, the institutes supporting the industrial clusters and the companies in great-sphere level is required. The purpose of this paper is for comparing and analysing the institutes supporting the industrial clusters and the companies in great-sphere level including various local governments. As the result of this research, four types of the cooperative industrial supporting systems among various local governments are divided: 1. inducing foreign direct investment into domestic area by regional development agency, 2. co-developing research parks or industrial parks by some local governments, 3. taking regional industrial statistics and writing development strategies over the boundary of the local governments, 4. constructing internet portal sites networking the local companies, universities, research centers of the same industrial cluster.
