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.

US DoD operated JCIDS(Joint Capability Integration and Development System) for top down requirement generation. Although the JCIDS can be a good practice for the countries which are trying to shift from bottom up to top down requirement generation, it contains many processes related with review and approval. In this study we structured a joint capability integration and development process from the JCIDS eliminating the organization dependent review or approval process so that it can be applied to any organization with some modification. Furthermore we implemented the process in the computer aided systems engineering tool, Cradle, for convenient use of the process. The result of this study can provide a basic process for top down capability development, and an efficient why of doing each element of the process using CASE tool.

More than 50% of defects and errors in the software development projects are related to the requirements[14]. But the development methodologies can not provide enough supports to the requirements management and changes. In the real world, the requirements keep changing as the requirements at the early development phase are usually incomplete, the developer′s understanding of the problem will be constantly changed during the software process, and new requirements may emerge with the organizational and environmental changes. In this paper, a requirements management process that can be integrated into the development methodologies is proposed to extend the requirements management over the whole development life-cycle and to support the requirements changes at the design/implementation/test phases. To evaluate the proposed process, it was compared to the existing requirements managements processes and models, and examined through a integration test with a widely used development methodology "MaRMI" to show the expected improvements at each development phase.

The train-centric control systems development has some distinct points in that a big size of government budget is in general expended in there and the development duration seems to be long. In addition, the changes are ever made continuously in the capability and operational requirements for Trains. Thus, the impact of the potential changes in the required operational capability on the development activities can induce some type of project risks [7]. As such, proper management of project risk has been one of crucial subjects in the train systems development. All these notes combined together make it the significance of the safety management process be raised further up in the train-centric control systems development. As such, the underlying safety management process should be capable of appropriately handling the potential risks that can be created due to the unexpected changes and the long-term development period. The process should also be complemented for the safety consideration of train-centric control systems, for instance, stop. To study these aspect is the objective of the paper. To do so, a step-by-step approach to analyzing the safety management process is first presented. Then, to enhance the process some necessary and useful activities are added in terms of risk and safety management. Then, to pursue some enhancement on the process, a set of necessary and useful activities are added in terms of risk and safety management. The resultant process is further analyzed and tailored using a design structure matrix method. The resultant process is applied in a train-centric control development as a case study.

RUP(Rational Unified Process) 객체 지향적이며 사용사례 및 아키텍처 중심의 반복적인 개발방법론이다. 이전에 수행된 대부분 공공분야의 대규모 소프트웨어 개발은 폭포수형 개발 프로세스를 적용하였으나 최근에는 소프트웨어 개발에 따른 위험을 최소화 하고 품질을 향상하기 위하여 RUP와 같은 반복 개발방법의 적용을 시도하고 있다. 그러나 대규모 복합 체계의 개발 프로세스와 그 일부인 소프트웨어 개발 프로세스로서 RUP를 적용한 국내의 연구 자료는 미흡한 실정이다. 본 논문에서는 RUP를 기반으로 복합 체계의 일부인 소프트웨어를 개발하는 프로세스를 고찰하고자 한다. 이를 위하여 국내 CIS 소프트웨어 개발 사례를 통하여 체계개발 프로세스와 통합된 RUP프로세스를 제시하고 기존의 폭포수형 프로세스 및 RUP와 비교 경가론 한다. 된 논문의 연구결과는 공공기관에서 대규모 복합체계의 소프트웨어를 개발하는 경우에 RUP 기반 프로세스의 조정, 개발관리에 있어서 위헌의 최소화와 최종 제품의 품질향상에 기여한 것으로 믿는다.

In this paper, we propose development of new products including the proposed process of at the customer's requirements. The success of new product development depends on customer satisfaction in the marketplace. Existing product development process, including the customer's interest was weak. In this paper, we propose development of new products which include Kano's attractive quality factor method and Timko's customer satisfaction index method. Also we verified new medical treatment of incontinence-nency which is applied to the proposed process.

New technology development capability plays a key role in making small- and medium-sized enterprises (SMEs) increase their innovation performance, such as in product or process innovation. To examine the influencing factors of SMEs' new technology development capability, this study empirically analyzes the mediating effects of SMEs' process design capability and product interior design capability on the positive association between their external information network diversity and new technology development capability. This study performs the ordinary least squares regression on a sample of 2,000 South Korean SMEs. Results reveal that SMEs' process design capability fully mediates, and product interior design capability partially mediates the positive association between the external information network diversity and new technology development capability.

The Systems Engineering, as a methodology for engineering and management of today's ever-growing complex system, is a comprehensive and iterative problem-solving process. The process centers on the analysis and management of the stakeholders'needs throughout the entire Life-cycle of a system and searches for an optimized system architecture. There are many essential needs and requirements to be met when a system development task is carried out. Systems Engineering Management PLan(SEMP), as a specification for system development process, must be established to satisfy constraints and requirements of stakeholders successfully and to prevent cost overrun and schedule delay. The paper suggests a systematic SEMP development process and demonstrates a data model and schema for computer-aided systems engineering software, RDD-100, for use in the development and management of SEMP These are being applied to the systems engineering technology development task for the next-generation high-speed railway systems in progress.
