본 연구의 목적은 농산물 이력추적 시스템을 사용하는 생산자들의 시스템에 대한 만족과 지속적인 사용의도에 영향을 주는 요인을 파악하여 농산물 이력추적 시스템의 활성화를 위한 기초자료를 제공하는 것이다. 실증적인 검증을 위하여 재사용의도와 관련한 선행연구들을 검토하여 TAM과 ECT를 결합시킨 Extended ECT 모델을 제안하고 실제 농산물 이력추적 사업에 시범참여하고 있는 생산자 100명을 상대로 설문조사를 실시하였다. 분석 결과, 지각된 유용성 및 용이성, 수익성은 시스템 만족에 긍정적인 영향을 미치며 이는 지속적인 사용의도로 연결되었으나 지각된 용이성과 유용성이 직접적으로 지속적인 사용의도에 영향을 미치는 것은 아닌 것으로 나타났다. 이 결과는 농산물 외의 식품 이력추적 시스템에도 포괄적으로 적용이 가능하다.

철도차량에 RFID 시스템을 도입함으로써 철도 부품관리 등을 포함한 철도차량의 스마트한 운영관리가 가능하도록 하는 것은 경제적, 산업적 뿐 아니라 사회적으로도 많은 필요성이 대두되고 있다. 본 논문에서는 해외의 RFID 연구 및 개발 활용사례를 조사 분석하였다. 철도 뿐 아니라 다양한 산업분야에 RFID 기술이 적용된 사례에 관해서도 조사하였다. 철도분야에서는 주로 차량위치 검지, 차량인식 등에 RFID 시스템이 사용된 경우가 거의 대부분이었고 부품의 단순이력 관리 등에 응용한 사례도 있었다. 본 연구를 통해, 세계적으로 이미 여러 산업분야에서 RFID 기술이 활용되고 있고 철도분야에서도 여러 국가에서 RFID 기술을 활용한 운영이 활성화되어 있으나 이러한 기술 활용은 주로 차량운행과 관련된 분야에 국한되어 있고 철도부품의 유지보수 등의 분야에서는 RFID 기술개발 및 활용이 미흡하다는 것을 알 수 있었다. 따라서 국내의 철도차량의 스마트한 운영관리를 위해서는 RFID 기술을 철도부품의 유지보수 및 이력관리에 적용할 수 있는 시스템이 반드시 필요하다.

The objective of this study is to suggest the templates for the terminology standardization cases of safety standard on integrated management system, so that integrated management of safety standards is introduced to replace redundant, or conflicting functions and performance of these standards. And to carry out the terminology standardization enables management efficiently. Therefore this study suggests and analyzes cases of terminology standardization of domestic and international research trends. In addition to proposes a architectural schema for disaster safety standard and writing disaster safety standardizations of the International Organization for Standardization. For the objectives, the guidelines on standard terminology policy, terminology publication and guide development proposed by the International Organization for Standardization. Disaster safety standards were applied in order to build and utilize integrated management system of disaster safety standards through domestic and foreign cases. Throughout the result of this study, this study will contribute to the analysis and application of semantic knowledge based analysis throughout the ontology information linked the vocabulary to vocabulary by making the template of the disaster safety standards for easy to use and simple etc. This study is to expect traceability for the principle national disaster safety standards resource elements.

A high-speed rail system represents a typical example of large-scale multi-disciplinary systems, consisting of subsystems such as train, electrical hardware, electronics, control, information, communication, civil technology etc. The system design and acquisition data of the large-scale system must be the subject under strict configuration control and management. Not only the requirements of the large-scale system dictate the contracts with the suppliers but also become the basis for the development process, project execution, system integration, and testing. The requirements database provide the system design specification of all development activities. Using the RDD-100, a systems engineering tool, the Korea next-generation high-speed rail program can establish requirements traceability and development process management in performing the enabling train technology development projects. This paper presents the results from a computer-aided systems engineering application to the Korea next-generation high-speed railway project. Especially, the focus of the study was on requirement management and PBS(Product Breakdown Structure) management.

In this paper, the QFD(quality function deployment) technique is used to acquire the quality requirements of package software which is sold in commercial software shop. To select the principal quality characteristics of package software, an user survey was conducted for a quality model developed based on the international standards and the previous research. The software user is divided into three groups: the general user, the expert, and the developer. Based on the survey results, the top 10 quality characteristics are selected including accuracy, suitability, installability, de-installability, and maturaty. Then, the QFD technique is applied to choose the software quality attributes which have strong correlation with the selected quality characteristics, some of which are traceability, accuracy, modularity, completeness, and self-descriptiveness. The developed procedure can be used in evaluating the quality of package software with lower costs and efforts.

Modern naval ships are large complex systems with the number of requirements ranges from thousands to tens of thousands. To build a quality ship, the satisfaction of the requirements should be traced. In most shipbuilding projects it is almost impossible to manage all the requirements without a proper CASE (computer aided systems engineering) tool. And for effective management of the shipbuilding project, the integrated database for technical data is very important. This paper describes how the requirements are managed, and the integrated database is built in the naval shipbuilding industry in Korea.

As technology develops, more advanced technologies involving GPS, GIS, RFID and sensor networks have been adopted in agriculture sector for u-Farm. However, technology adoptions have been evaluated as ineffective. Farmers and agri-business have low level of understanding on technology so it is not efficiently utilized. This study introduces a case of RFID/sensor networks of mushroom farm as a u-Farm case study, focusing on developing a framework for analysis of u-Farm investment returns. RFID and sensor networks improve real-time production control, processing management, and traceability. Integration of RFID and sensor networks leads to innovation into the mushroom farm, reducing labor cost, increasing productivity, and improving quality of the mushroom. The ROI which is used as an indicator of performance indicator is 413%.
