Currently, the commercialization of the 5th Generation (5G) service is becoming more prevalent in domestic communication network technology. This has reduced communication delay time and enabled large-capacity data transmission and video streaming services in real-time. In order to keep pace with these developments, K-water has introduced a smart process control system in water purification plants to monitor the status of the water purification process. However, since wireless networks are based on the public Long Term Evolution (LTE) network, communication delay time remains high, and high-resolution video services are limited. This is because communication networks still have a closed structure due to expense and security issues. Therefore, with 5G in its current form, it is very difficult to accommodate future services without improving the infrastructure of its communication networks. In recognition of these problems, this study implemented the authentication and management function of wireless networks on a wired network management system in the K-water Bansong water purification plant. The results confirmed that wired Local Area Network (LAN) services give a higher security performance than an expensive commercial wireless LAN system. This was achieved by using an Internet Protocol (IP) address management system of wired networks and the packet filtering function of the Layer2 (L2) switch. This study also confirmed that it is possible to create a wireless LAN service that is 3.7 times faster than the existing LTE communication network.

Project management is a tool for smooth operation during a full cycle from the design to normal operation including the schedule, document, and budget management, and document management is an important work for big projects such as the JRTR (Jordan Research and Training Reactor). To manage the various large documents for a research reactor, a project management system was resolved, a project procedure manual was prepared, and a document control system was established. The ANSIM (Advanced Nuclear Safety Information Management) system consists of a document management folder, document container folder, project management folder, organization management folder, and EPC (Engineering, Procurement and Construction) document folder. First, the system composition is a computerized version of the Inter-office Correspondence (IOC), the Document Distribution for Agreement (DDA), Design Documents, and Project Manager Memorandum (PM Memo) works prepared for the research reactor design. Second, it reviews, distributes, and approves design documents in the system and approves those documents to register and supply them to the research reactor user. Third, it integrates the information of the document system-using organization and its members, as well as users’ rights regarding the ANSIM document system. Throughout these functions, the ANSIM system has been contributing to the vitalization of united research. Not only did the ANSIM system realize a design document input, data load, and search system and manage KAERI’s long-period experience and knowledge information properties using a management strategy, but in doing so, it also contributed to research activation and will actively help in the construction of other nuclear facilities and exports abroad.

본 연구에서는 유비쿼터스 식물공장의 재배환경에 필요한 요소들의 센서 네트워크를 구성하고 자동으로 감지하여 적응형 뉴로-퍼지 추론시스템을 통하여 환경변화를 추론하여 식물공장의 재배환경을 적절하게 제어할 수 있는 새로운 자동제어시스템의 프레임워크를 제안하고, 이를 설계하였다. 유비쿼터스 식물공장 환경을 제어하기 위하여 식물공장의 재배환경에 영향을 미치는 환경요소인 실내온도, 근권온도, 습도, 광도, CO2 농도를 측정할 수 있는 센서 네트워크를 구성하고 측정된 환경요소의 변화에 따라 램프, 환기, 습도, CO2 농도, 온도를 제어할 수 있는 장치를 자동으로 제어할 수 있는 식물공장 자동제어시스템을 설계하였다. 이를 위하여 본 연구에서는 센서를 통하여 받아들이는 입력값을 퍼지소속함수로 변화하고 적응형 뉴로-퍼지시스템에 따라 추론하고 평가하여 보다 정밀하게 식물공장을 자동으로 제어할 수 알고리즘을 개발하였고 이를 구현하였다. 개발된 자동제어시스템을 상추 식물공장에 적용한 결과 만족스러운 시험결과를 얻을 수 있었다. 향후 연구로는 식물공장에서 재배하고 있는 작물별 생장모델의 적합도 검정 및 개선을 위하여, 작물별 재배규칙을 보다 상세히 도출하는 것이 필요하고, 작물의 재배에 필요한 지식을 보다 정량적으로 표현하고 지식상에 내포하고 있는 불확실성을 해결하는 것이 필요하다. 더 나아가 식물공장에서 환경인자간의 상호관련성을 보다 정밀하게 수식화하고 이를 추론할 수 있는 정밀하고 과학적인 자동제어시스템의 개발이 필요하다.

대규모 국방획득사업의 성공측도는 사업 일정과 비용을 효과적으로 관라하여 작전요구성능을 만족하는 것이며，사업의 효과적 일정 및 비용 관리를 위하여 사업성과관리체계(EVMS，eartned value management system)가 도입되었다. 사업성과관리체계(EVMS)는 실비용(AC, actual cost)의 신뢰성을 확보하기 위하여 기업의 경영정보시스템(MIS, management information system)으로부터 원가정보블 제공받도록 발전하였으며，사업성과관리체계의 축적된 실비용 정보를 원가정산시 훨용하고자 하는 연구가 진행되었다. 그러나 기업의 경영정보시스템내 원가정보의 강제적 제출은 영업비밀에 속하는 지적재산권 분쟁의 소지가 있다. 본 논문은 사엽성과관리체계와 원가정산 사스템 통합에 영향을 미치는 요인들을 지적재산권음 고려하여 분석하였다.

Survival and development of manufacturing business depends on how the companies make competitive product and put out on the market. In other words, the core competitiveness of manufacturing business is "product" and companies’ competitiveness and sustainable growth could be guaranteed by management from product deveIopment to release onto the market. However, there are few examples about establishing successful system yet. The purpose of this study is to analyze on how PLM affect the performance. In particular, findout how iIlegal copying of PLM system that contains know-how gives company negative effect and emphasize why companies should recognize the importance of iIIegaI copying.

최근 보고에 의하면 국내 노인의 인구 비율은 2000년에는 7.2%이었고, 2019년에는 인구의 14.4%가 노령인구가 되는 초고령화 사회가 되며, 이는 노인들의 치매, 섬망, 우울 또는 가성치매, 편집상태, 건망 증후군 등으로 인한 천문학적인 사회 비용이 지출되고 있다. 이중 노인치매의 경우 인지기능뿐 아니라 본인의 삶과 가족을 황폐화시키는 결과를 초래하는 병으로 국내뿐 아니라 전 세계적으로 치매예방을 위한 많은 연구와 개발이 이루어지고 있다. 본 연구에서는 원거리 도서민의 치매예방을 위한 게임요법으로 음악요법과 운동요법을 활용한 실버댄스게임을 개발하여 치매를 사전에 예방하고, 체력을 향상시키며, 체계적인 관리가 가능한 통합관리시스템을 개발한다.

The Chicago Convention in 1944 made important contributions to aviation safety improvement, building an aviation safety monitoring system for its signatory countries. As ICAO is now on the verge of changing its supervision system from self-reporting to preventive Continuous Monitoring Approach(CMA) in 2013, we also expect our own safety system to make a progress accordingly. The government is pushing ahead with plans to build an integrated safety management system at government level that satisfies international standards and reflects domestic features. To this end, this report proposes the most effective system-building model, by analyzing the current status of the system that is in use and meets the requirements of international aviation agencies.

The small and medium construction companies are facing potential EHS(Environment, Health & Safety) of major accidents to cause casualties or a financial loss and increasing social responsibility. So, they have to voluntarily accomplish the EHS management system rather than passively with regard to EHS regulation. In this study, the framework of integrated EHS management system is developed based on cloud computing, and construction companies are to materialize self-regulation EHS process of construction workplace and to standardize the total EHS business process using the developed system. The proposed system also provides risk analysis, education/control and continuous improvement for EHS tasks and users can easily access the system on the web at a low price through cloud computing service. Eventually, the integrated system contributes to the managerial improvement by minimizing economic and physical loss caused by construction accidents.

Establishing a framework, to explain the path to safety accidents considering major safety management factors such as physical conditions including on-site activities and workplace, as well as human factors as to labor, supervisors, or managers, would be effective as the basis to control project's risks by preventing disasters. Therefore, this study aimed to clarify the mechanism in safety management and disaster occurrence. In order to accomplish the purpose, it identified and classified the factors related to accidents, reviewed the causal relationships among them, and suggested the influence diagram. The results of this research are expected to contribute to reinforcing the preventive management, and facilitating the development of integrated site control system based on safety risks.
