공공사업의 경우 다중 프로젝트, 메가 프로젝트 등 다양한 발주형태로 건설사업이 추진됨에 따라 복합적이고 다원적인 관리가 필요하다. 건설사업관리를 효과적으로 하기 위하여 PMIS가 널리 사용되고 있으나 현재 대다수의 PMIS는 단일프로젝트 중심으로 개발되어있어 전체 사업관리를 위한 시스템 통합과정에서 시스템 간의 호환성 문제가 발생한다. 또한 공공사업 중심으로 사업과정에서 BIM을 적용하도록 한 발주가 증가하였으나, 아직까지 BIM을 활용한 사업관리를 위한 BIM 데이터 연계 PMIS의 개발 및 연구가 부족한 실정이다. 따라서 본 연구에서는 PMIS As-Is분석과 To-Be분석을 통해 다중복합 프로젝트 PMIS의 주요 목표기능을 도출하고 Internet-Intranet의 이원화 관리체계를 분석하여 통합사업관리체계를 적용한 PMIS 발전모델과, 상용 BIM Tool과 PMIS를 직접 결합하는 방식이 아닌 BIM 기술의 순차적인 적용방안을 통하여 통합사업관리시스템에 적합한 BIM 기반 PMIS 구축방안을 제시하여, 궁극적으로 BIM 기술의 활성화에 대비한 단계별 PMIS 발전 모델을 제안하는데 그 목적이 있다.

Recently, internal information leaks is increasing rapidly by internal employees and authorized outsourcing personnel. In this paper, we propose a method to integrate internal control systems like system access control system and Digital Rights Managements and so on through expansion model of SIEM(Security Information Event Management system). this model performs a analysis step of security event link type and validation process. It develops unit scenarios to react illegal acts for personal information processing system and acts to bypass the internal security system through 5W1H view. It has a feature that derives systematic integration scenarios by integrating unit scenarios. we integrated internal control systems like access control system and Digital Rights Managements and so on through expansion model of Security Information Event Management system to defend leakage of internal information and customer information. We compared existing defense system with the case of the expansion model construction. It shows that expanding SIEM was more effectively.

A nuclear power plant (NPP) is a highly complex system-of-systems as manifested through its internal systems interdependence. The negative impact of such interdependence was demonstrated through the 2011 Fukushima Daiichi nuclear disaster. As such, there is a critical need for new strategies to overcome the limitations of current risk assessment techniques (e.g. the use of static event and fault tree schemes), particularly through simulation of the nonlinear dynamic feedback mechanisms between the different NPP systems/components. As the first and key step towards developing an integrated NPP dynamic probabilistic risk assessment platform that can account for such feedback mechanisms, the current study adopts a system dynamics simulation approach to model the thermal dynamic processes in: the reactor core; the secondary coolant system; and the pressurized water reactor. The reactor core and secondary coolant system parameters used to develop system dynamics models are based on those of the Palo Verde Nuclear Generating Station. These three system dynamics models are subsequently validated, using results from published work, under different system perturbations including the change in reactivity, the steam valve coefficient, the primary coolant flow, and others. Moving forward, the developed system dynamics models can be integrated with other interacting processes within a NPP to form the basis of a dynamic system-level (systemic) risk assessment tool.

Both the national land plan and the environmental plan reflect the need for sustainable land use and management. However, the linkage between the plans is reduced due to the lack of integrated management. Therefore, this study developed indicators to achieve integrated management. A total of 59 environmental plans were reviewed for the development of indicators, and a total of 74 integrated management indicators were derived through a three-stage process. In this process, the relevance of the integrated management indicators of this study to the UN 's sustainable development goals (SDGs) is presented in order to derive indicators that meet the level of international consultation. In order to facilitate the utilization of the indicators, the final indicators are divided into seven areas: natural ecology, water resource and quality, urban and green space, atmospheric, energy, landscape, resource circulation and waste. Furthermore, the indicators were classified into national, regional, and city level. Accordingly, the final indicator can be adapted to the field of influence of the planned to be established, and the indicator can be selected and applied to the level of the plan. The final indicators can be used to examine the extent to which the national plan reflects the contents of the environmental plan and can be used as an aid to confirm the contents to be included in the plan when establishing a new national plan.

To develop a sailing yacht successfully, systematic engineering information is required including technologies from various companies and know-how about sailing yacht. The engineering information about sailing yacht has a complex and extensive structure. Therefore, a robust and high-level of management system is needed to manage the information. In this paper, we design and propose Generic-YWBS (Generic-Yacht Work Breakdown Structure), a work breakdown structure for sailing yachts. The Generic-YWBS is aimed at constructing sailing yachts and contains contents about product- and process-oriented information of sailing yachts. In addition, the Generic-YWBS plays an important role in managing the engineering information as a basic schema of database and system architecture. The Generic-YWBS is derived from fundamental WBS design processes and various rules about sailing yachts, for example, ISAF (International Sailing Federation) equipment rule and IRC rating rule, and a generic structure concept is applied for flexibility. The Generic-YWBS is applicable for various purposes. We designed a detailed code system in order to apply the Generic-YWBS to contents management system. The series of activities are realized through a web-based RIA(Rich Internet Application) program. This program manages the YWBS structure in an XML schema, and the Generic-YWBS management application offers a customizing function to be adapted in the field.

As cyber attacks become more intelligent, there is difficulty in detecting advanced attacks in various fields such as industry, defense, and medical care. IPS (Intrusion Prevention System), etc., but the need for centralized integrated management of each security system is increasing. In this paper, we collect big data for intrusion detection and build an intrusion detection platform using deep learning and CNN (Convolutional Neural Networks). In this paper, we design an intelligent big data platform that collects data by observing and analyzing user visit logs and linking with big data. We want to collect big data for intrusion detection and build an intrusion detection platform based on CNN model. In this study, we evaluated the performance of the Intrusion Detection System (IDS) using the KDD99 dataset developed by DARPA in 1998, and the actual attack categories were tested with KDD99's DoS, U2R, and R2L using four probing methods.

Automated Storage and Retrieval System (AS/RS), which is an element of Computer Integrated Manufacturing (CIM), is a widely used material handling equipment with conveyors and Automatic Guided Vehicles (AGVs). Until now the evaluation of operational policies of AS/RS and control algorithms is done theoretically or by computer simulations. In this study, a real-time control and monitoring software of an AS/RS is also developed by making actually moving AS/RS miniature. A PC-based real-time monitoring program can control the AS/RS directly through the communication port. The monitoring program has additional functions such as storage/retrieval management, inventory management, and statistics management. The program can not only collect the necessary statistics but monitor the current action of the AS/RS concurrently.
