  • The protection of nuclear safety software is essential in that a failure can result in significant economic loss and physical damage to the public. However, software security has often been ignored in nuclear safety software development. To enforce security considerations, nuclear regulator commission recently issued and revised the security regulations for nuclear computer-based systems. It is a great challenge for nuclear developers to comply with the security requirements. However, there is still no clear software development process regarding security activities. This paper proposes an integrated development process suitable for the secure development requirements and system security requirements described by various regulatory bodies. It provides a three-stage framework with eight security activities as the software development process. Detailed descriptions are useful for software developers and licensees to understand the regulatory requirements and to establish a detailed activity plan for software design and engineering.

  • Currently, our society is showing many changes due to the influence of information and communication technology (ICT). At the center of these information and communication technologies are software, intelligence, and sensing technologies. The software-related industry is steadily developing due to various software development policies implemented by the government and related organizations. Software development is desirable, but on the other hand, some negative aspects are also appearing. In this study, we proposed an objective way to infer the progress of software development for reasonable resolution of cases when a dispute related to the progress of development occurred during the software development process. The proposed solution was based on the waterfall model. The outputs generated in each process of the waterfall model are contents excluded from subjectivity. Therefore, it can be used as an objective method for calculating software development progress.

  • 컴포넌트 기반 소프트웨어 개발 방법은 새로운 패러다임으로 인식되고, 활발한 연구가 진행되고 있다. 그러나 컴포넌트 기반 개발에서 컴포넌트의 재사용성과 효율적인 소프트웨어 개발을 보장하기 위해서는 소프트웨어 아키텍처를 기반으로 한 개발이 필요하다. 본 논문에서는 컴포넌트 기반 소프트웨어 개발을 지원하기 위해, Kruchten이 제시한 4+1 뷰 모델을 기반으로 재 정의한 컴포넌트 기반 4+1 소프트웨어 아키텍처 뷰 모델을 제안한다. 또한 뷰 모델의 요소와 UML을 이용한 뷰 모델 요소의 표현을 제시한다 이 아키텍처는 컴포넌트의 사용문맥을 각 뷰에 반영함으로써 소프트웨어에 대한 이해와, 컴포넌트의 상호 작용에 대한 정보 등 컴포넌트 기반 소프트웨어 구성에 대한 틀을 구성한다.

  • 객체지향 모델은 구조적 모델에 비해 모듈성, 재사용성, 유지보수성, 확장성 등의 장점을 제공한다. 이러한 이유로 객체지향 소프트웨어 개발 방법들을 정보 시스템 개발에 광범위하게 적용되고 있다. 그러나 현재의 객체지향 소프트웨어 개발 방법들은 목적 소프트웨어 시스템의 객체지향 모델링을 지원할 뿐, 방법론 그 자체는 구조적 및 절차적 체계를 기반으로 하고 있다. 본 논문에서는 객체지향 소프트웨어 개발 방법론을 객체지향적으로 모델링한 OMOS(Object-oriented software development Method for Object-oriented software System)를 제시한다. OMOS에서는 개발 산출물과 관련된 활동이 객체로써 모델링 되며, 개발 생명주기 프로세스가 객체간의 상호작용으로 모델링 된다. 소프트웨어 개발 방법론의 객체지향적 모델링은 방법론 자체의 재사용성, 유연성, 확장성, 유지보수성의 용이성 등의 장점을 제공한다.

  • The completeness appraisal of software is performed in various forms, such as assessing the completion level in the development process, calculating the defect rate, estimating the development cost, and calculating the redevelopment cost. Along with this, the problem that is often dealt with is estimation of the development time. Even in a dispute over completeness due to delays in software development, issues of calculating an appropriate development time required to develop a delivery software or a development time required for change requests are often included in the appraisal request. In this paper, we introduce the procedure and method for estimating the appropriate project time of software development so that the appraiser can be applied to the appraisal work for determining the completeness. The method is based on the manual for calculating the appropriate project period of software development project.

  • The importance of software development in the integration of an avionics system is continuously increasing. And we can expect enlarged soft ware portion in the system integration for the more intelligent, reliable, and automated avionics system. For an avionics system software development the selection of a real-time operating system and internal avionics data bus protocol is very important from the viewpoint of the integration with the system hardware. In this paper, we present current trend of an avionics system software development including software development methodology, software development process, and international software process assessment improvement model.

  • As the requirement of user for robot functionality, the function and interface for controlling the robot system is more sophisticated and complicated. Accordingly development process of robot is more complicated and it takes much longer time to develop a robot system. Software development using project management tool is more important in software engineering because of the complexity of software, especially robot system. This paper proposes SEED (Software Engineering Equipment for Development), which is a web-based and integrated software engineering tool to provide independent tools for robot software development. SEED includes the document management tool, the software configuration management tool, the software testing tool on developing robot software and provide a functionality of collaborated and remote development due to WEB-based operations.

  • This paper proposes a framework for product development including hardware and software components. The framework provides separation of the hardware dependent software, an integrated product development process, and integration of software components with product configurations and product structures. In order to separates the hardware dependent software, the framework considers product configuration modules and engineering changes of associated hardware and software components. The proposed product development process integrates development of the hardware dependent software into the existing product development process. In order to integrates the hardware dependent software with product configurations and product structures, the framework represents software components by existing product data models in Product Data Management (PDM). The framework is applied to development of a robot system including hardware and software components in order to show its effectiveness.

  • The rapid growth of communication and globalization has changed the software engineering process. Security has become a crucial component of any software system. However, software developers often lack the knowledge and skills needed to develop secure software. Clearly, the creation of secure software requires more than simply mandating the use of a secure software development lifecycle; the components produced by each stage of the lifecycle must be correctly implemented for the resulting system to achieve its intended goals. This study demonstrates that a more effective approach to the development of secure software can result from the integration of carefully selected security patterns into appropriate stages of the software development lifecycle to ensure that security designs are correctly implemented. The goal of this study is to provide developers with an Integrated Security Development Framework (ISDF) that can assist them in building more secure software.
