웹의 짧은 역사에 비하여 웹 관련 기술이 급속히 발전하고 있다. 이것에 비하면 웹 어플리케이션의 품질 개선 속도는 이에 따르지 못하고 있다. 따라서 웹 시스템 개발에 대한 효율적인 개발 방법이 필요하다. 본 논문은 웹 시스템을 개발하는데 필요한 항목들을 기술하였다. ISO/IEC 12207표준에 근거하여, 웹을 기반으로 하는 소프트웨어 개발 모형을 분석 및 설계 단계를 중심으로 제시하였다. 컨텐츠를 웹 어플리케이션에 반영하기 위하여 프로세스와 엔터티 정의방법을 기술하였다. 본 모형을 사용한 KCC 정보통신(주) Web-RoadMap 방법론을 공공 프로젝트에 적용하였다. 적용결과 효율적인 웹 어플리케이션의 분석 및 설계의 한 모형임을 입증하였다.

As the competition between countries has become higher and the notion of software quality has been widely spread. it has been necessary to develop technologies that can ensure and produce high quality software. With the advent of information-oriented society. quality control has to transfer to the quality control activities focused on software system instead of those activities focused on hardware system. If so, how do we get to handle the quality control on the basis of the new approach. Also, as software applications have grown. so too has the importance of software quality. In order to manage software quality, the technology to specify and evaluate both the software product quality and development process quality objectively quantitatively is most important. To produce products of good quality, we need a more progressive quality control system according to the need of software development life cycle. In other words, we do software right the first time or build quality in the process. On the basis intermediate and final time or build quality in the process. On the basis of data achieved, we can evaluate the products according to the consequences of the data, What are the problems to contrive the software quality control system?, we con promote the quality of products. To achieved that goal, we con provide a suitable the technique and method of software quality control.

This paper presents a new approach to automotive embedded systems development and validation. Recently automotive embedded systems become even more complex and the product life cycle is getting reduced. To overcome these problems AUTOSAR, a standardized software platform and component based approach, was introduced. Model-based approach has been widely applied in the development of embedded systems and has strong benefits such as early validation and automated testing. In this paper cooperative development and validation of AUTOSAR and model-based approach are introduced and automated testing techniques are proposed. With the proposed techniques we can improve complexity management through increased reuse and exchangeability of software module and automated testing is realized.

Software verification and validation(V&V) is a means to develop high-quality software and assure safety and reliability for software. Also, we can achieve the desired software quality through systematic V&V activities. The software to be applied safety critical system like nuclear power plants is required to setup the V&V methodology that comply with licensing requirements for nuclear power plants and should be performed V&V activities according to it. In this paper, we classified safety-critical, safety-related and non-safety for software according to safety function to be peformed and define V&V activities to be applied software grade. Also, we defined V&V activities, procedures and documentation for each phase of software development life cycle and showed techniques and management to perform V&V. Finally, we propose the V&V framework to be applied software development of SMART(System-integrated Modular Advanced ReacTor) MMIS (Man-Machine Interface System) and to comply with domestic licensing requirements.

Pursuing sustainable development throughout society and industry and the field of environmental policy, each international organization or nation has performed international standardization projects on environmental management activities for their system as well as environmental assessment for a product such as life cycle assessment (LCA) and life cycle inventory database (LCI DB), and the environmental aspects have been increasingly demanded as crucial evaluation specifications. Moreover, the conventional environmental policy, which represents the direct-control, has been more dependent on the market forces and product itself after the Climate Change Convention., and the Integrated Product Policy (IPP, EU) is applied vigorously to strengthen global competitiveness of a product and to achieve the effect of environmental improvement for it. According to change of the international railway market, the value of Eco-Design has been increasingly important in developed countries including EU. Thus, each country is establishing its own guidelines, software and database for each product, and developing new policies through Eco-Design with practical results in marketing. To react this and develop Korean railway as an environment-friendly industry with priority to other transportation system as well as maintain high place in technology, the direction of RACE software development of main function is introduced, which is exclusively used for EMU to assess both environmental and economic aspects with LCA and eco-efficiency (EE).

원자력 산업계는 최근 원전 계측제어계통 설비의 단종과 같은 예상치 못한 환경에 직면해오고 있으며, 이러한 문제를 근본적으로 해결하고자 노력하고 있다. IAEA, IEC, 등의 연구결과에 따르면, FPGA는 단종이 예상되는 제어계통에의 대체수단으로 주목받고 있다. FPGA가 원자력 플랜트의 PLC(Programmable Logic Controller)를 대체하기 위해서는 높은 건정성과 신뢰성을 가져야 한다. 따라서, FPGA 기반 제어기의 건전성과 신뢰성을 향상시키기 위하여 HDL 개발수명주기를 적용하여 개발하였다. 또한, 원전 계측제어계통에 적용하기 위하여 번인시험과 환경시험의 기기검증이 수행되었다. 시험수행결과, 352시간의 번인시험과 92시간의 환경시험 중에 정상적인 기능 및 성능을 수행함을 확인할 수 있었다.

소프트웨어 개발에서 점점 더 중요시되는 사항은 개발 생명주기의 초기에 개발과 관련된 노력과 비용을 추정하는 능력이다. 소프트웨어 개발노력과 비용추정을 위한 대부분의 모델이 선형회귀분석 절차를 사용하였다. 그러나 소프트웨어의 복잡성, 개발환경의 다양성으로 인해 소프트웨어 개발노력과 비용 추정은 점점 더 부정확해지고 있다. 이 목적을 달성하기 위해서는 비선형 방법을 사용해야 한다. 따라서 본 논문은 소프트웨어 개발 노력을 추정하는데 비선형 관계를 표현 가능한 RBF망 모델을 제안한다. 24개 소프트웨어 사례연구를 통해 적합한 RBF 망 모델을 제시하였다. 또한, 회귀분석 모델과 RBF망 모델을 비교하여 RBF 망 모델의 정확성이 가장 좋음을 보였다.

In the current software project, it is still very difficult to extract and define clear requirements in the requirement engineering. Informal requirements documents based on natural language can be interpreted in different meanings depending on the degree of understanding or maturity level of the requirements analyst. Also, Furthermore, as the project progresses, requirements continue to change from the customer. This change in requirements is a catastrophic failure from a management perspective in software projects. In the situation of frequent requirements changes, a current issue of requirements engineering area is how to make clear requirements with unclear and ambigousrequirements. To solve this problem, we propose to extract and redefine clear requirements by incorporating Design Thinking methodologies into requirements engineering. We expect to have higher possibilities to improve software quality by redefining requirements that are ambiously and unclearly defined.
