  • The reactor protection system is the most important function for the safe operation of nuclear powerplants (NPPs) in that such system protects a nuclear reactor tore whose damage can cause an enormous disaster to the nuclear facility and the public. A digital reactor protection system (DRPS) is being developed in KAERI for use in the newly-constructed NPPs and also for replacing the existing analog-type reactor Protection systems. In this paper, an software verification and validation (V&V) activities for DRPS, which are independent of the DRPS development processes, are described according to the software development life cycle. The main activities of DRPS V&V processes are the software planning documentations, the verification of software requirements specification (SRS) and software design specification (SDS), the verification of codes, the tests of the integrated software and system. Moreover, the software safety analysis and the software configuration management are involved in the DRPS V&V processes. All of the V&V activities are described, in detail, in this paper.

  • The importance of software industry is rapidly increasing with the growth of Internet and the advent of digital economy. The purpose of this study is to research the impact of the copyright protection for securing producers and enhancing of producing on social welfare. The Korean government reformed the copyright law to enhance the copyright protection in 2000 and intensely controlled software piracy in 2001. However, copyright protection has much controversy in aspects of hindering social use of software. This study compared and analyzed the general equilibrium and the copyright protection for social welfare maximization in two cases when network externality exists or not, by assuming the simple demand and supply functions.

  • This paper describes the application of a software fault tree analysis (FTA) as one of the analysis techniques for a software safety analysis (SSA) at the design phase and its analysis results for the safety-critical software of a digital reactor protection system, which is called the KNICS RPS, being developed in the KNICS (Korea Nuclear Instrumentation & Control Systems) project. The software modules in the design description were represented by function blocks (FBs), and the software FTA was performed based on the well-defined fault tree templates for the FBs. The SSA, which is part of the verification and validation (V&V) activities, was activated at each phase of the software lifecycle for the KNICS RPS. At the design phase, the software HAZOP (Hazard and Operability) and the software FTA were employed in the SSA in such a way that the software HAZOP was performed first and then the software FTA was applied. The software FTA was applied to some critical modules selected from the software HAZOP analysis.

  • 본 논문에서는 인터넷에서 암호화 방법을 이용하여 소프트웨어의 불법사용을 방지할 수 있는 시스템을 설계하였다. 현재의 대부분 소프트웨어들은 저작권 보호를 위하여 Lock Key등과 같은 물리적인 장치를 사용하지 않고 사용상의 편의성 때문에 설치 암호를 입력하는 방식을 이용하고 있다. 따라서 암호만 알면 누구나 소프트웨어를 자유로이 이용할 수 있기 때문에 정품 소프트웨어를 구입한 사용자가 의도적으로 암호를 노출시킬 경우 라이센스 수량 이상으로 불법사용 될 수 있다. 본 논문에서 제안한 시스템을 이용할 경우 소프트웨어 사용자는 라이센스 수량만큼만 동시에 사용할 수 있음으로 소프트웨어의 불법사용을 원천적으로 봉쇄할 수 있다. 또한 소프트웨어 개발자는 판매 수량을 정확히 파악할 수 있음으로 경영에 도움을 받을 수 있고 소프트웨어 사용자는 개발자로부터 소프트웨어의 유지보수를 신속히 받을 수 있다.

  • Information technology(IT) is changing rapidly based on growth of internet and computer businesses. Therefore, computer programs and softwares are distributed to computer users promptly for their productivity increase and efficient work. So, in the distribution, the softwares will be copied or released through network or other methods which are not authorized by the program owners. In that case, copyright dispute is incurred and various issues are come out due to infringement of the software copyright. Thus, the purpose of this study is to research infringement cases of the software copyright and how to settle the dispute which is related with software programs. To achieve the purpose of this study, this research consisted of 5 chapters. At chapter 1 introduction, it mentioned necessity of this study, purpose and how to research this study, and at chapter 2 dispute factors indicated and summarized for technical resolution. At chapter 3, infringement cases of software copyright analyzed and studied upon intellectual property(IP) related laws. And methods of dispute settlement discussed and suggested to chapter 4 for copyright and intellectual property protection. Also, it emphasized importance of arbitration to resolve the issues timely and avoid time and economical consumption. Of course, arbitration law has to be matched with the trend of technology development for effective settlement. At chapter 5 conclusion, it summarized this research and suggested further research for empirical test of economic value of the software copyright upon the aspect of business, law, and engineering. In this study, the results are 1) IP related laws have to be enacted or revised to meet technical changes for the protection of software copyright on time. The enactment or the revision of law takes a long time, therefore, to deal the dispute effectively, 2) arbitration law has to be utilized efficiently in order to resolve issues and settle the dispute promptly. It is suggested the dispute settlement through arbitration to save time and economic matters for legislation, and to harmony with the technology trends. 3) Recognition of software copyright is to be improved by users and enterprises for development of software related industries and intellectual property protection. In conclusion, the protection of software copyright is important than any other things in the field of IT because of the development of industry and intellectual property related laws. The development is for areas of business, law and engineering, so research and practices are to be combined with the areas so that it could resolve the dispute settlement and IP protection effectively.

  • The social and economic level of damages might be highly increased in the case of wide-area black-outages, because of heavy dependence of electricity. Therefore, the development of a wide-area protection relay intelligence techniques is required to prevent massive power outages and minimize the impact strength at failure. The frequency monitoring and prediction for wide-area protection relaying intelligence has been considered as an important technology. In this paper, a network-based frequency monitoring system developed for wide-area protection relay intelligence is presented. In addition, conventional techniques for frequency estimation are compared, and a method for advanced frequency estimation and measurement to improve the precision is proposed. Finally, an integrated monitoring system called K-FNET(Korea-Frequency Monitoring Network) is implemented based on the GPS and various energy monitoring cases are studied.
