Recently, in according as rapid improvement of telecommunication markets and wireless internet technology, Location- Based Services (LBS) have been discussed as new 'Killer' application. The purpose of LBS is to determine location of user through mobile handset and to offer location information service to end-user. This paper has suggested an efficient transmission scheme of maps data as one of the important content services relating to data transmission of LBS in mobile environment. The basic system consists of three parts : (1) GIS (Geographic Information System) Server for storing, processing and handling map data, (2) Middleware Server for transmitting of map data by request of client, and (3) Client for requesting map data to Server and displaying them on handset. Also, in order to transmit map data, we are to expand WKB (Well Known Binary) in conformance to Simple Feature Specification of OGC (Open GIS Consortium), and increase efficiency of data transmission by developing trans mission data format to be able to transmit lightweight data and considering data compression technology.

최근 웹 확산에 따른 일반인들의 인터넷 이용이 급증하였고 이에 따른 정보 기술도 빠르게 변화하고 있다. GIS 분야에서도 시대의 흐름에 맞춰 지리정보 데이타를 웹상에서 제공하는 웹 GIS 분야가 등장하게 되었다. 그러나, 상호 이질적인 지리정보 데이타를 웹 기반 분산 환경에서 서비스하기 위해 표준 인터페이스와 각각의 웹 서비스 모델을 정의한 통합 시스템이 요구되고 있다. OGC(OpenGIS Consortium)에서는 기존 OpenGIS(Open Geodata Interoperabillty Specification)의 상호운용성을 웹 환경에서 지원하고, 또한 상호이질석인 지리정보의 접근을 위해 새로운 웹 맵 서버인터페이스 구현 명세(Web Map Server Interface Implementation Specification)를 제안하였다. 웹 맵 서버 인터페이스 구현 명세는 웹상에서 공간 질의를 처리하기 위안 URL 컴포넌트를 정의하고 있으며, URL 형식의 클라이언트 질의를 수행한 결과를 웹 브라우저에서 이미지 포맷으로 지리정보를 제공한다. 본 논문에서는 OGC가 최근 제안한 XML(eXtendible Markup Language)기반의 표준 공간 데이터 포맷인 GML(Geography Markup Language)과 웹 맵 서버 인터페이스를 이용해 분산된 지리정보 데이터를 웹 브라우서를 통하여 서비스할 수 있는 웹 맵 서버를 설계 및 구현하였다. 따라서 클라이언트는 본 논문에서 개발한 웹 맵 서버를 통하여 별도의 응용 프로그램을 개발하지 않고도 다양한 GIS 시버들의 종류와 위치에 관계없이 표준 인터페이스를 통해 이를 GIS 서버들로부터 공간 데이터를 접근할 수 있다.

This paper describes implemation of 'General-purpose ETRI MAP interface module' (GEM) for Mini-MAP network. GEM operates as a Mini-MAP node in our FA system. To communicate between GEM and programmable devices(PD) such as PLC and CNC, serial communication is used. Application programs of a MiNi-MAP host system control and monitor programmable devices via GEM. GEM is implemented and tested on the basis of the MAP 3.0. TBC in the Nini-MAP board performs the function of the MAC sublayer. The LLC sublayer is implemented according to the specification of Class 3 that includes Type 1 and 3. And the MMS services are designed within the scope of implementation class MAP3. All the softwares are implemented under the real-time multitask OS for real-time application of the Mini-MAP and they are loaded into PROMs at the network board of GEM. We tested the LLC functions to make use of a protocol analyzer for the token-passing protocol. Also the MMS conformance test was carried out by exchanging primitives between GEM and a MMS product that had already passed the conformance test. Therefore GEM is proposed as a network tool of Computer Integrated Manufacturing (CIM) to integrate PDs which don't support MAP functions.

We present a method for initialization of asynchronous circuits using binary decision space representation. From state transition graph(STG) which is given as a specification a circuit, the BDD is generated to solve the state space explosion problem which is caused by concurrecy of STG. We first step, we construct the necessary informaton as a form of K-map from BDD, then find an initial state on the K-map by assignment of don't care assignment.

Manufacturing Message Specification(MMS) was sewed as an International Standard by International Standardization Organization(ISO). MMS is being accepted throughout the world as a solution to communications among multi vendor factory floor environments. This paper describes an implementation of MMS which operates on Application Layer of Open Systems Interconnection(OSI) 7 layer model. MMS was implemented on MSDOS in apersonal computer environment.

MMS (Manufacturing Message Specification) is a communications standard of MAP (Manufacturing Automation Protocol), which is a Network Protocol for Industrial Automation. In the environment of Mini-MAP, MMS is situated in the application layer and on the LLC (Logical Link Control) layer. In this paper, MMS software is implemented on the basis of ISO DIS 9506. The implemented software was tested with Token Passing Bus Network Interface Unit, which was designed in our laboratory and performs the actions of layer 1 and 2.

Network systems are of fundamental importance in programmable device in industrial automation, as they essential in order to active group management of integration and coordination. In this papers,MMS implemented on the basis ISO specification for industrial environment. In the MMS-MAP, MMS is situated in the application layer and on the datalink layer. This implemented software was operated with network interface unit which was designed in group objects and service primitives for group management network model system. This function of designed module showed possibility of operation through group state diagram transition in the Mini-MAP environment.

Technology of GIS evolved as a means of assembling and analyzing diverse spatial data. Many systems have been developed, and almost of systems are proprietary. There is a lots of lack of interoperability and reusability between them. This paper describes the development of Open GIS component software. The developing system have an end in view of GIS tool software which is interoperable and reusable. To increase the interoperability and reusability, the system is based on the OGC(Open GIS Consortium)'s Open GIS Simple Features Specification for OLE/COM. The OGC's specification is announced to increasing the full interoperability of various geospatial data and geoprocessing resources. With the Open specification, component based software ensures the reusability. We implement three kinds of component: Geometry component, Spatial Reference System Component, and MapBase Component. The first two components are compatible to the OGC's specification and the third one is designed to GIS tool software for variant GIS applications. The Open GIS component software system is developed on object-oriented computing environment, ATL/COM and Visual C++. As we made application programs using Visual Basic, the advantages of component based Open GIS software was proved.

Purpose: The purpose of this study was to explore roles of cancer care coordinator's by developing job description, job specification and job process map using dynamic job analysis. Method: The development process consisted of three stages of vertical job analysis and three stages of horizontal job analysis by modifying Song(1997)'s dynamic job analysis. Focus group interview was used to validate the content of the job analysis. Results: Cancer care coordinator's job description was categorized into six major categories, fourteen intermediate categories and one hundred forty specific jobs. Major categories are professional nursing practice, consultation and counsel, coordination and collaboration, education, research and leadership. Cancer care coordinator's job specification included master's degree with over five years of clinical experience preferably relevant clinical area, professional knowledge on pathophysiology of cancer, case management and cost control, competency for communication and counselling skills and clinical decision making. Cancer care coordinator's job process map was framed with time(horizontal) and activities(vertical). Conclusion: The Outcomes of this study will guide to develop possible areas of oncology advanced practice nurses in hospital setting and facilitate the use of oncology nurse practitioners by developing care coordinator roles in cancer care.
