기존의 산업단지 개발은 대규모 단일 공간 집적형태로 신규 부지를 활용하여 개발하는 방식이나 4차 산업혁명 시대는 스마트한 기술적용과 융복합화를 지원할 수 있는 새로운 입지모델 개발이 필요하다. 따라서 본 연구에서는 새로운 산업단지 공급유형으로 단일공간에 대규모로 집적하는 형태가 아닌 다수의 공간에 분산 배치하여 연계하는 방식으로서 '네트워크형 산업단지'를 제시하였다. 새로운 입지모델 개발을 위해 기업체 설문조사를 실시한 결과, 약 89%의 기업이 네트워크형 산업단지의 필요성을 인식하였으며, 동 산단의 활성화를 위한 조건으로서 '상호 보완기능형성', '결절지간 교통편리성'을 선택하였다. 네트워크형 산업단지는 도시공간과의 개방 연계 지향 및 기반인프라 공유 등을 통해 저비용 고효율화 산단으로 기능할 것으로 전망된다.

The main purpose of this study is to substantiate the theoretical and methodological foundations of the organizational and economic mechanism of development of the agro-industrial complex in modern conditions. Organizational and economic mechanism is presented as a complex organizational structure of the system type, which is aimed at performing specific functions, the characteristic feature of which is the constant support of process changes without which the organizational and economic mechanism can not exist. There are four components of the agro-industrial complex, represented by agriculture and the national economy, which ensure its operation, including industry, processing of agricultural products, its storage and transportation, sale and repair and maintenance of agricultural machinery and more. It is proved that the organizational and economic mechanism of development of agro-industrial complex in modern conditions it is expedient to consider: from the point of view of system and process approaches; as a set of economic levers and organizational measures to influence the agro-industrial complex; constituent components of organizational influence on the development of the complex; a set of components, elements that are integrated into the system of economic relations of the subjects of the agro-industrial complex; a set of purposeful stimulators of agro-industrial complex development. The functions of the organizational component of the mechanism of agro-industrial complex include: redistributive, planning, interaction, control, integration and regulatory functions, the functions of the economic component include consumer, investment and innovation, social, incentive, monitoring functions of the mechanism. The symbiosis of the functions of organizational and economic components ensure the effectiveness of the organizational and economic mechanism of the organizational and economic mechanism through its functionalities as a whole.

본 연구에서는 5G 네트워크용 UAV(: Unmanned Aerial Vehicle)를 사용한 산업단지 내의 현장 상황을 실시간 감시하는 시스템에 대해 소개한다. UAV에 장착된 센서(화재, 유해가스 검출, 산업 재해형 인체 사고 감지)에서 모니터링 이벤트가 발생하면 센서의 주요 정보들이 UAS(: Unmanned Aerial System)애플리케이션 서버로 전달한다. 이러한 정보 전달 처리결과로, 산업단지공단의 관리자나 운영자는 사고 위험 상황별 트리거 처리를 통한 산업단지공단 내의 현장에서 인명사고와 화재, 그리고 유해 가스검출에 대한 법적인 근거 자료를 확보할 수 있게 되었다.

The purpose of this paper is to classify zones disrupting green spaces in city and to evaluate of their grades. The results are as follows; L There were 158 green spaces in Dalsu-gu. The 158 green spaces were classified 4 patterns and minutely classified into 9 types. The area of the 'nature park' type was turned out to be $70.1\%$ of the total area of green spaces in Dalsu-gu, then the type was considered as a important part of the green-network in Dalsu-gu. The 9 types such as 'nature park', 'river', 'neighborhood park' and so on were analysed with ecological indexes. 2. Based on the ecological indexes of 'ratio of the green space', 'features of the surrounding matrix' and 'travel distance of the wildlives' , zones disrupting green spaces were ranging widely and re-divided to 236 sectors. 3. The analysis results for classifying the grades were that grade I appeared over industrial complex and housing complex widely. On the other side, grade II and III appeared around or between nature park and neighboring park Consequently, it was necessary to consider the grade and make zones disrupting green spaces into green space for improving green network.

본 연구에서는 경상남도 지역의 오염감시전용측정망의 5년간(2013 ~ 2017) 자료를 이용하여 주오염원과 분기별 지하수 수질특성을 분석하였다. 주오염원은 산업단지지역, 광산·폐광산지역 및 하수처리시설로 구별하였다. 분석 항목은 현장측정 항목(수온, pH, 전기전도도, 용존산소, 산화물환원전위), 양이온 그리고 음이온이었다. 수온과 pH는 주오염원에 따라 크게 변하지 않았다. 양이온과 음이온의 평균농도의 합은 산업단지지역에서 가장 높았고, 하수처리시설 그리고 광산·폐광산지역 순이었다. 산업단지지역에서는 전기전도도의 값이 가장 높았고, 용존산소의 값이 가장 낮았다. 산업단지지역은 나트륨이온이 가장 높은 구성비를 보인 반면 하수처리시설과 광산·폐광산지역에서는 칼슘이온이 가장 높은 값을 나타내었다. 모든 주오염원에서 중탄산염의 농도가 가장 높게 나타났다. 수온, pH 그리고 양이온과 음이온의 농도는 분기마다 크게 다르지 않았다. 수질유형 중 Na-HCO₃ 유형이 가장 높은 비율을 차지하였으나, 외부 오염의 가능성이 높은 Na-Cl 유형도 오염감시전용측정망의 전체 자료 중 약 20%를 차지하였다.

The data in automation and control systems can be achieved not only from different field devices but also from different OPC (OLE for Process Control) servers. However, current OPC clients can only read and decode the simple data from OPC servers. They will have some problems to acquire structured data and exchange the structured data. In addition to the large network control systems, the OPC clients can read, write, and subscribe to thousands of data points from/to OPC servers. Due to that, the most important factor for building a high performance and scalable industrial control system is the ability to transfer the process data between server and client in the most efficient and fastest way. In order to solve these problems, we propose a means to implement the OPC DA (Data Access) server supporting the OPC complex data, so that the OPC DA clients are able to read and decode any type of data from OPC servers. We also propose a method for caching the process data in large industrial control systems to overcome the limitation of performance of the pure OPC DA system. The performance analysis and discussion indicate that the proposed system has an acceptable performance and is feasible in order for applying to real-time industrial systems today.

As the modern industrial processes become more complex, it is getting more difficult to model and control the processes. Naturally, an advanced type of DCS(Distributed Control System) with higher level functions is being sought. Advanced DCS is a DCS with advanced functions such as fault diagnosis, GPC(Generalized Predictive Control), NN(Neural Network), and Fuzzy Control. In this thesis, we have studied a fuzzy control algorithm for realizing an advanced DCS. Its algorithm is implemented in a form of function code which is a process control language, being used by the industrial engineers. To verify the realized function code of the fuzzy control, the function code is applied to a continuous casting process of the Pohang Iron & Steel Works in Kwangyang. The rules of the fuzzy control were collected via interviews of the field operators and their operation documents. Finally under a real-time operating system environment, usability of the function code of the fuzzy control is shown via simulation for the continuous casting process.
