  • Design engineering process for field programmable gate array (FPGA)-based reactor trip functions are developed in this work. The process discussed in this work is based on the systems engineering approach. The overall design process is effectively implemented by combining with design and implementation processes. It transforms its overall development process from traditional V-model to Y-model. This approach gives the benefit of concurrent engineering of design work with software implementation. As a result, it reduces development time and effort. The design engineering process consisted of five activities, which are performed and discussed: needs/systems analysis; requirement analysis; functional analysis; design synthesis; and design verification and validation. Those activities are used to develop FPGA-based reactor bistable trip functions that trigger reactor trip when the process input value exceeds the setpoint. To implement design synthesis effectively, a model-based design technique is implied. The finite-state machine with data path structural modeling technique together with very high speed integrated circuit hardware description language and the Aldec Active-HDL tool are used to design, model, and verify the reactor bistable trip functions for nuclear power plants.

  • This paper was concerned about design and implementation of supply chain management for auto-part company by adopting a UML(Unified Modeling Language). The part of SCM and e-business have interested by larger company, researcher and academic professor. There has been known about a little implementing SCM and it's initiatives for SME(small-medium sized enterprise). We, in this paper, dealt with design and implementing the SCM on supply chain auto part SMEs. The UML is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. It simplifies the complex process of software design, making a blueprint for the SCM implementation. In this paper, we also adopt some methods for the systematic system analysis, design, and implementation by applying UML to a SCM system.

  • This paper describes the instructional flexible manufacturing system(FMS) laboratory facility at Virginia Polytechnic Institute(VPI) which is directed at problems and issues in the design, implementation and control of computer integrated manufacturing systems. It begins with a configuration and an operational description of FMS laboratory facilities. Next, relevant curricula in manufacturing systems design and control, which can use the FMS laboratory for instructional purpose, are introduced, A computer simulation can be used as an excellent tool for analysis prior to implementation of FMS as well as an on-going improvement tool. A brief survey of simulation languages is lastly included.

  • This paper summarizes available literature on the optimization of reinforced concrete (RC) beams. The objective of optimization (e.g. minimum cost or weight), the design variables and the constraints considered by different studies vary widely and therefore, different optimization methods have been employed to provide the optimal design of RC beams, whether as isolated structural components or as part of a structural frame. The review of literature suggests that nonlinear deterministic approaches can be efficiently employed to provide optimal design of RC beams, given the small number of variables. This paper also presents spreadsheet implementation of cost optimization of RC beams in the familiar MS Excel environment to illustrate the efficiency of the exhaustive enumeration method for such small discrete search spaces and to promote its use by engineers and researchers. Furthermore, a sensitivity analysis is performed on the contribution of various design parameters to the variability of the overall cost of RC beams.

  • The statistical survey and analysis is much restricted to time, space and material. The statistical survey and analysis could hardly resume. The statistical survey and analysis is very important to create various and accurate information. The statistical survey and analysis which is not a expert knowledge have many problems in productivity of information, reliability and etc. In this paper, we study the design and Implementation of web-based statistical survey and analysis consulting system which a client meet easily a statistical expert on the web.

  • This paper proposes a technical requirements analysis of implementation of multi-trade prefabrication. Recently, there has been a rise in the use of prefabrication to minimize on-site work for time reduction to increase productivity. Prefabrication technique is evolved into multi-trade prefabrication combining other trades from single-trade prefabrication. For implementation of new technique, not only itself but complementary techniques have to be prepared. In this paper, MEP corridor rack, a major item of multi-trade prefabrication, was implemented in the test bed and its process was analyzed to find out technical requirements. As a result, comparatively high level of IT technique was required for efficient use of multi-trade prefabrication in design, lifting and construction phase. In design phase, component level of BIM library was needed for manufacturing; and in lifting phase, BIM-based site logistics process was required. Also in construction phase, laser scanning was implemented for gathering shape and geometry of the wall and slab that were attached to multi-trade prefabrication module.

  • 급격히 변화하고 있는 21세기 현대 사회에서 국가 경제력을 갖춘 인재 양성을 위해 최근 미국, 영국 등 선진국을 중심으로 STEM(Science Technology Engineering Mathematics) 교육이 점차 강조되고 있으며 우리나라에서는 Arts(예술)를 추가하여 STEAM(Science Technology Engineering Arts Mathematics) 교육이 나타났다. 융합(STEAM) 교육 목표는 기존의 주입식 및 암기식 교육이 아닌 학습자들의 흥미도와 학습에 대한 동기 부여를 강화하여 체험, 탐구, 실험이 중심이 되어 융합적 사고와 실생활 문제를 해결할 수 있는 능력을 갖추어 국가 경제력을 강화하는 것이다. 본 연구가 이루어진 Y 초등학교에서는 세계 공용어로 자리매김한 영어와 4차 산업 혁명으로 인한 발전으로 거의 모든 분야에서 찾아볼 수 있는 과학을 융합하여 학습자들이 주도적으로 수업에 참여하여 문제해결능력을 향상할 수 있는 PBL 모형과 ADDIE 모형이 기반이 된 수업 모형을 설계하였다. 이 모형은 크게 5가지 절차로 분석(Analysis), 설계(Design), 개발(Development), 실행(Implementation), 평가(Evaluation)로 구성된다. 국가 경제력을 갖춘 인재 양성이라는 목표도 중요하지만, 교육 현장에 있는 교사들이 융합(STEAM)교육의 중요성을 인지하고 이에 알맞은 수업 설계에 관한 연구가 지속하며 강화되어야 한다.

  • The subject on office automation is gradually gaining more improtance due to the fact that the efficiency of office systems contribute to the increase of productivity as much as manufactoring systems themselves. For successful implementation of office automation, one must carefully plan and execute various steps such as the analysis of office tasks, personnel training, workplace design, equipment design, and so on. The previous studies related to the subject has not been concrete enough to be practically helpful for the actual realization of office automation. In this paper, a new analysis method of the office task is proposed. This analysis method is based on the Rasmussen's and Bennette's methods. The Rasmussen's method describes a way of quantifying mental workload while the Bennette's method provides a tool for the analysis of the office task. The posner's and Rouse's methods are also employed for the detailed division of tasks. The method proposed in this paper is believed to be easier for use and expected to be more helpful for us to cope with the clear definition of office tasks that is vital to successful implementation of office automation.

  • 소프트웨어 개발은 보통 요구사항, 분석, 설계, 구현, 그리고 테스팅의 5단계의 과정으로 이루어진다. 개발과정 중 시스템 설계의 빈번한 변화와 그에 따른 프로그래밍의 어려움으로 인한 시스템 설계와 구현 사이에 항상 불일치가 발생하게 된다. 본 논문에서는 시스템 설계와 구현 사이의 불일치를 줄이고, 소프트웨어 개발이 신속하고 유연하게 되도록 비즈니스 로직을 인식하여 응용프로그램을 생성시켜주는 도구를 설계하였다. 응용 프로그램 생성기의 핵심 아이디어는 같은 영역에 있는 비즈니스 애플리케이션을 첫째, 공통의 비즈니스 로직과 화면표시 로직으로 나누어 인식한다. 둘째, 시스템 디자인을 지속적인 메타데이터로 다룬다. 셋째, 지속적인 메타데이터를 사용해서 요구사항에 맞는 비즈니스 에플리케이션을 구축하거나 커스터마이즈한다.
