  • 이 연구는 전거통제를 위한 상호협력시스템으로서 발전을 거듭하고 있는 미국의 NACO의 역사와 발전과정, PCC와의 관계 등에 대해 고찰하고, 한국의 도서관에서의 활용방안에 대해 구체적으로 분석하였다. 광범위한 전거데이터의 활용이라는 면에서 NACO는 유용한 대안이 될 수 있으나, 표목 및 접근점의 선정과 형식에 관한 표준의 문제, 로마자화의 문제, 수록데이터의 유용성, 비용, 정책상의 문제 등도 충분히 고려해야 함을 지적하였다. 아울러 국내의 경우에도 이와 같은 전거통제를 위한 상호협력시스템이 필요하다는 점에서, NACO는 하나의 좋은 모델이 될 수 있을 것이다.

  • Presented in this paper is a control model for developing virtual factory simulator, which is being operated under the distributed environment. The control model consists of production activity plan and information flows. To incorporate elements of the characteristics of the distributed control system, we suggested a collaboration model. This model is working under the client/server architecture, and also designed for cooperative-distributed shop control(CDSC) system in order to exploit several advantages of client/server architecture. Collaboration among each agent(or client) is done through negotiation and task sharing. Based on a contract net model, the CDSC system has three kinds of agents-order agent, resource agent, and communication forwarding agent. Each agent performs shop scheduling and control through negotiation on contract net. No node in CDSC system can have authority over other node. A bidding scheme is employed far negotiation between order agent and resource agents. The CDSC system can support re-negotiation among resource agents and an algorithm for re-negotiation is also developed. Experimental results are shown to advocate the effectiveness of the CDSC system for CIM environments.

  • An SADT-based methodology is presented for systematically analyzing the container working process in container terminal, as well as an object-oriented design method for an integrated information system for container terminal resource planning and management. Our design architecture is composed of four levels, activity interface, activity PDCA control, human resource management, and facility resource management. Especially, the consideration of the human resource management level makes it possible to support cooperative tasks, to make the authority and responsibility on a task clear, and to extremely promote the balance between human and facility resources. Finally, The system architecture is suggested for Virtual Container Terminal, in which a planned container working process is simulated for previous feasibility check, work orders are transferred to control real devices, and to manage the entire process and related data.

  • The current road traffic signal controller developed in the 1990s has limitations in flexibility and scalability due to power supply problems, various communication methods, and hierarchical black box structures for various equipment and devices installed to improve traffic safety for road users and autonomous cooperative driving. In this paper, we designed a road traffic safety facilities equipment and devices integrated management system that can cope with the rapidly changing future traffic environment by solving the using direct current(DC) and power supply problem through the power over ethernet(PoE) technology and centralized data-driven control through message broker technology. In addition, a data-driven real-time control method for road traffic safety facilities equipment and devices operating based on time series data was implemented and verified.

  • Public library legislation is the essential means of providing for all the citizen in modern society with a standard public library service. We can trace the origin of that back to the Public Libraries Act 1850 in England. This paper is reviewing all the measures concerning public libraries of England since then in order to find out some guidelines for revision of the Korean Library Law enacted in 1963. Although Public Libraries Act 1850 was an output of a series of social reform movement in the 19th century, it established first the provision of public library service su n.0, pported by public funds. However the Act had several restrictions hindering public library service from making progress. These are: 1. Adoptive legislation in nature 2. Limitation of the size of population and rate income 3. Small library authorities 4. Procedure for adoption by public meeting 5. Restrictions on the ways in which rate income might be spent 6. No governmental organization to direct or control for a standardized public library service 7. No cooperative schemes among libraries. Subsequent development was directed largely to removal of those limitations. The present Public Libraries Act 1964 as a model of public library legislation was enacted on the basis of such reports as Kenyon, McColvin, Roberts, and Bourdillon. All but the problem of small library authorities were removed with this new Act. The final object could be achieved by the Local Government Act 1974 which reorganized existing 383 small authorities into new 115 ones the average population of which was 280, 000. Now, McColvin's dream of 30 years could be fulfilled in the late 70's. He argued that the minimum size of population of a viable authority should be 300, 000. Although the effect of the 1964 Act on the development of public library services in England was great, there must be some considerations as to the provisions of public library objective, government funding for library services, free use of library materials to all regardless of residence, and placement of library committee within the authority.

  • Korean fishery wage system has been evolved with the different titles. However, Since the law of fishing crew was enacted in 1984, the fishery wage system has been established as a rate system, which is a legal term. The present rate system in practice shows various contents and modalities, depending on fisheries and regions, but the fisheries of large trawl cooperative employ a rate system of fixed plus rate wage. However, such change did not transform basically the properties of pure rate scheme. As well known, fishing vessel owners face an awful lot of difficulty in managing and controlling effectively the production process because fishing activities are carried out in the seas remote from the land. Thus, it tend to be inevitable for vessel owners to employ a rate system to induce fishermen's positive motivation for promoting productivity and saving operating costs. However, the rate system has worked out as a driving force, which induce an increase in production more strongly under the expansion of vessel numbers and power and the keener competition of fishing activities. Even though the control mechanism of fishing instruments are well established, fishermen become naturally to have an incentive to increase their fishing effort for maximizing production since they are able to raise their shares by maximizing the quantity harvested. Thus, as far as the rate system exists, fisheries administration may have much difficulty in realizing its fishery management goals only through vessel reduction and fishing gear regulations. Also, under the rate system fishery management authority may be in face of a serious dilemma between the spontaneous rate system and vessel reduction policy. If the realistic aspect of the rate system is recognized and resource restoration and profit promotion are main policy goals, it is necessary to develop effective ways to control vessel owners' and fishermen's production-maximizing motives at an appropriate level. From this point of view, it seems reasonable to introduce TAC system by species or by fisheries into the existing fishery system. The research results suggest that if the fisheries administration could understand clearly the spontaneous fisheries wage system, it would know the norm of TAC and the basic reasons for illegal fishing activities and thus it would be able to develop and implement more realistic resource management policies.

  • This study aims to identify the recent trends and intellectual structure of international research in the field of catalog, which is undergoing a major change due to the enactment of new standards and rules and the anticipated future. For this purpose, we collected 680 articles published in the 14 years since 2010 and analyzed 1,942 author keywords extracted from them after preprocessing. The main findings of the analysis are as follows First, overseas cataloging research has seen notable growth since 2017. Second, the most frequent research topics were: cataloging, metadata, RDA, university libraries, authority control, linked data, FRBR, catalog, LCSH, libraries, andonline cataloging. Third, the research themes were divided into two clusters, one related to the traditional aspects of library cataloging and the other related to the more recently discussed topics of authority control, cooperative cataloging, RDA, and linked data, which were further subdivided into 14 subclusters. Fourth, we looked at the growth index and standard performance index of the 14 keyword clusters and found that all but one cluster showed growth in terms of discipline growth. This study is significant in that it can be used as a basis for predicting the future development of inventories for Korean academia and the field and for related education.

  • This study purpose to examine the importer's risks that may arise from origin investigation by Customs authorities. We have drawn the important factors affecting the application of FTA preferential tariffs and divided the stages from the conclusion of the contract for the importer to the undergoing origin investigation. In addition, we demonstrate empirically that the risks that arise in areas where importers are difficult to control exist. As a management method of the uncontrollable risk from the importer, we have provided the methods that the seller stipulated the seller's responsibility in the trade contract, prepared for situations in which no one was responsible, and formulated a friendly and cooperative supply chain. Even if the seller's liability is clarified in the contract for sale, the risk of the investigation into the origin of the imported goods is not completely eliminated. This is because, under the current agreement and system, there is no way for the customs authority of the contracting party of the FTA to claim compensation for damages incurred by importers due to breach of agreement such as not returning the result of the origin verification. Importers are subject to customs duties, but there may actually be situations in which no one is responsible for them.
