As part of effort to reduce the process time from design to manufacture and delivery, the concept of CE(concurrent engineering) has been applied to design process. In this research, the drawing information management system (DIMS) was developed based on CE. The system can distribute electronic documents of drawing or work instruction parallel to all reviewers simultaneously and collect their annotations through network. Mark-up functions are used for annotations on the electronic documents. DIMS is a system which integrates drawing management, engineering BOM, CAD and raster drawings, etc. In this system, a SUN workstation is interfaced with PCs by LAN. CIMCAD-2D, Image Hunter, and ORACLE RDBMS are used for CAD drawings, raster drawings, and drawing information management, respectively. As an integration tool for all the information, LINKAGE is adopted.

For the implementation of CE(Concurrent Engineering), the TDMS(Technical Document Management System) which integrates design and manufacuring information, is required. In this paper a drawing information management system, one of the essential modules for the TDMS has been developed. The system is operated in SUN SPARC II workstations. A CAD software called CIMCAD-2D is used for the storage and management of drawings. Relational DBMS ORACLE is used for the development of information data bases concerned with drawings. As an integration tool, the multi-media software called LINKAGE is used. Various functions for drawings and concerned information have been developed with the internal language CIMSHELL and SQL $^*PLUS$.

Although the importance of information security industry has been growing these days, the research of industrial respect for the industry has been rarely performed. This paper provides one definition of the information security industry and the industry classification system according to the definition. The purpose of this study is to provide the basic data for the industry development strategy by analyzing economic ripple effect on the domestic information security industry.

Big data is a key driver of the fourth industrial revolution, represented by ultra-connected, ultra-intelligence, and ultra-convergence, and it is important to create innovation and share, link, and utilize data to discover business models. However, it is difficult to secure and utilize high-quality and abundant data when big data platforms are built in a regular manner without considering shared-linked. Therefore, this paper presents the development direction of big data platform infrastructure by comparing and analyzing various cases of big data platforms to enable data production, construction, linkage, and distribution.

Recently, by applying the 4th industrial revolution technologies such as A.I., IoT, and big data to general residential infrastructure, various application services of residential-based are provided to residents through linkage and utilization between technologies. Accordingly, smart housing system is increasing as advanced living spaces that can improve the quality of life and convenience of residents. Such a smart housing is expected to be an item that can create new demands and markets in the construction industry since it provides a new paradigm that combines construction technology and IT by combining IT technology with existing construction industry. Based on this, it is expected that it will be possible to gradually develop large-scale markets such as smart buildings and smart cities. In this paper, therefore, we propose an artificial intelligence multiplex smart housing system as an intelligent platform that can autonomously manage and control the size of places and spaces, used for various purposes based on smart housing technology by using artificial intelligence systems.

The aim of this study is to propose the design suitable for sustainability evaluation model of the mobile industry considering system process (SEP). Although a quantitative evaluation was conducted on the link between the national sustainability report and the mobile industry, it was confirmed that it was difficult to identify stakeholders. So it is necessary to develop the design process suitable for the more operator-specific interfaces. The Human System Integration (HSI) methodology was proposed through linkage with work domain analysis. Agile methodology and Resilience engineering methodology were added for sustainable model design. The proposed sustainability system evaluation model is applied so that it can be easily used in all industries.

With the introduction of China's new policies, the Chinese animation industry has gradually formed a sustainable industrial structure chain, and the output value of the animation market is also in a state of continuous growth. Since 2013, domestic animation has been developing from "lower age" to "ageing" and "adults". At the same time, with the popularization of China's pan-entertainment industry model, the multi-domain symbiosis of the Internet and mobile Internet has been realized, creating a fan economy of star IP (Intellectual Property), and promoting the linkage of various industries under the same IP. This paper mainly analyzes the development of the animation IP market in China's pan-entertainment mode in recent years, and analyzes the cross-media operation mode of the animation industry. At the same time, it studies the application of self-media in animation.

Large earthquakes with (M_W > ~ 6) result in ground shaking, surface ruptures, and permanent deformation with displacement. The earthquakes would damage important facilities and infrastructure such as large industrial establishments, nuclear power plants, and waste disposal sites. In particular, earthquake ruptures associated with large earthquakes can affect geological and engineered barriers such as deep geological repositories that are used for storing hazardous radioactive wastes. Earthquake-driven faults and surface ruptures exhibit various fault zone structural characteristics such as direction of earthquake propagation and rupture and asymmetric displacement patterns. Therefore, estimating the respect distances and hazardous areas has been challenging. We propose that considering multiple parameters, such as fault types, distribution, scale, activity, linkage patterns, damage zones, and respect distances, enable accurate identification of the sites for deep geological repositories and important facilities. This information would enable earthquake hazard assessment and lower earthquake-resulted hazards in potential earthquake-prone areas.

최근 정보통신기술의 발달과 개인 스마트기기 성능의 상향평준화로 멀티미디어 콘텐츠의 사용량이 증가하고 있다. 멀티미디어 서비스를 제공하는 기업들은 사용자 경험을 개선하기 위해 조회 수를 기준으로 우선순위를 부여하는 콘텐츠 배치 전략에 따라 엣지에 우선순위가 높은 콘텐츠를 배치한다. 이러한 방식은 우선순위가 아닌 콘텐츠들을 사용자에게 서비스할 때 콘텐츠 전달 속도가 증가한다. 본 논문에서는 이러한 차순위 콘텐츠들의 전달 속도를 개선하기 위하여 CDN 기반의 콘텐츠 선호도에 따른 Edge-Fog 연계 Caching 기법을 제안한다.

중대재해처벌법(이하 "동법" 병기) 시행 전후로 동법에 대응하기 위한 정부 지원과 학계 연구는 많이 진행되어 왔으나, 대부분은 사전 예방에 치중되어 재해 발생 이후 기업 운영상의 리스크 관리나 피해경감 등을 위한 연구가 부족하였다. 중대재해를 줄이기 위해서는 사전 예방이 우선이지만 재발방지 및 추가 피해 최소화 노력도 뒤따라야 한다. 따라서, 본 논문에서는 재난 및 업무중단성 사고에 대하여 예방, 대비, 대응 및 복구활동에 필요한 문서화된 관리체계를 규정하고 있는 재해경감활동관리체계(이하 "동 체계" 병기)를 활용하여 중대재해처벌법을 준수할 수 있는 방안을 연구하였다.
