In the perspective of service, it is important to institute certification process required by International Standard Organization (ISO) for software (SW) development process, since Information and Communication Technology (ICT) takes high portion of the Korean industry and its certification for SW is essential internationally for trade. In addition, the certification service provided by BPMN tools like ADONIS is absolutely necessary. In that perspective, this paper proposes a new approach to satisfy this kind of necessity. This approach provides the certification service for the safety of SW required at the international level in Korean industry. Furthermore, the approach can be applied to other domains beside the SW. In order to demonstrate the approach, this paper shows how to guarantee service design for certification of ECSS-E-40 of European Space Agency (ESA) with ADONIS. This paper focuses on specification and verification of SW in E-40, and the main requirement for the verification will be safety of the SW.

In shipbuilding industry, the manufacturing technology has advanced at an unprecedented pace for the last decade. As a result, many automatic systems for cutting, welding, etc. have been developed and employed in the manufacturing process and accordingly the productivity has been increased drastically. Despite such improvement in the manufacturing technology, however, development of an automatic system for fabricating a curved hull plate remains at the beginning stage since hardware and software for the automation of the curved hull fabrication process should be developed differently depending on the dimensions of plates, forming methods and manufacturing processes of each shipyard. To deal with this problem, it is necessary to create a "plug-in" framework, which can adopt various kinds of hardware and software to construct a full automatic fabrication system. In this paper, a framework for automatic fabrication of curved hull plates is proposed, which consists of four components and related software. In particular the software module for computing fabrication information is developed by using the ooCBD development methodology, which can interface with other hardware and software with minimum effort. Examples of the proposed framework applied to medium and large shipyards are presented.

It is inevitable to control the systematic failure to obtain the software safety integrity of embedded software installed in rolling stock. Because it is not possible to assess systematic failure integrity by quantitative methods, SILs are used to group documentation, methods, tools and techniques throughout software development lifecycle which, when used effectively, are considered to provide an appropriate level of confidence in the realization of a system to a stated integrity level. Normally, safety approval process is through generic product, generic application and specification application for. For safety approval on generic application of software based system, it is required to apply the certified software processes from the planning stage for the assigned SIL. As such, we will develop project specific application with high safety integrity within time limit of contractual delivery schedule through software assessment to the modified area with the re-use of certified software module and documentation. At this point, Hyundai Rotem has developed software processes applicable to support SIL 4 based on EN50128 which was assessed and certified by TUV SUD. This paper introduces the Hyundai Rotem's detailed approach and prospective action to achieve software safety integrity level.

In this paper, we introduce the software and hardware of the measurement system for on-line testing and evaluation of high speed railway. The test items focus on the verification of the performance and acquirement of the technical data of the high speed railway system. The software controls the hardware of the measurement system, perform the analysis and calculation of measurement data and acts as interface between users and the system hardware. For this purpose, three programs a measuring program, a monitoring program and post-processing program are developed. The detailed test scenario is in the process of development to closely follow the process of development and design of the system.

In software development process, increasing the size of project(scaling up) is not a same problem as scaling up the parts of small project. Scaling up a project should accompany the communications, and cost, productivity, qualities, development activity, methodologies etc should be considered with it. In this paper, the effective usage of the important elements are discussed in order not to fail to scale up a project.

In this paper, we focus on the process of using open source software (OSS) and factors that should be considered when using project-based OSS. We also elaborate on how to avoid using OSS licenses in an OSS-based technology development process, why dual OSS licenses and security threats should be avoided, and the method of notification after use. In addition, the OSS license verification method and environment are described in the course of project development. In the verification method, the OSS license used for technology development in the course of project execution is validated in advance by the person who decides whether or not to use the OSS, and then additional verification using the tool after technology development. It is expected that this paper will be helpful for establishing the OSS usage consideration and the license verification procedure, and environment in the future.

In this study, PC controlled CNC automatic cutting system is developed. Technological introduction of the control process and the computer programming has made possible not only the automatic control for cutting processing unit but also the easy-to-use graphic software that enables the cutting process. This program involves shape part drawing and amendment, pattern reading and saving, reading Autocad file, nesting process, kerf compensation, automatic cutting path generation, NC file conversion and motor control. Software is devided into 3 modules for easy work. First step enables drawing, amendment and pattern making, followed by automatic nesting and cutting path generation with kerf compensation. In the final step, drawing data is transmitted for the resulting automatic cutting processes. This software would be applicated in gas cutting and textile cutting so that it improves the productivity of cutting process.

The need to accommodate much complex algorithm. high communication functionality and easier user interface lays heavy burden on the software developer of the protection relay these days. Using lightweight real-time kernel like uC/OS, the software development process can have much structural and easier feature. And total cost needed to development and maintenance of the software also can be reduced by development based on these real-time kernels.

Recently, design patterns have been known to be highly effective and practical. Design pattern is a collection of collaborating classes that captures the application independent behavior of system in a particular domain. By using design pattern, the development time and software quality can be greatly increased. However, systematic development process and detailed instructions of building design patterns have not been studied enough. In this paper. we propose practical intranet structure modeling technique that are based on design pattern. The proposed process consists of the four typical software development phases; analysis, navigation, interface, behavior domain design, and each phase is defined as a logical sequence of development tasks. Since the proposed process is based on design pattern foundation, and can be efficiently produced by applying this process.

Software Process Improvement(SPI) has been a challenging issue to software organizations. The factors affecting SPI were analysed for improving software development processes. Numerous studies suggested influencing factors, and assessment models were utilized for software improvement. This research suggested that SPI factors affecting on an organizational performance may vary according to the CMM(Capability Maturity Model) level. The moderating effects of organizational maturity level between the SPI factors and the organizational performance were empirically tested. This research found that all six SPI factors except for the resistance to change affected the organizational performance. The moderating effects of management support, goal alliances, participation, and effect analyses were empirically supported. These results can provide several implications or a practical guidance to academic and industry professionals.
