One of the activities to improve software quality in ISO 26262 is to apply the design principles for software unit design and implementation mentioned in ISO 26262-6, including the evaluation activity. Before evaluation activity, the tool is compared and selected for evaluation. Because the results of the tool a company selected might have an effect on product quality. In this paper, we suggest the method to compare industrial static analysis tools with some of "MISRA C : 2004 Exemplar Suite" and all lessons learned from comparing tools are described. The result on comparison shows that we just couldn't rely on a result of Static Analysis Tool and need to have another appropriate processes and guidelines to evaluate a software.

In an environment where manufacturing conditions such as product lines keep changing, manufacturing control systems need to be continually maintained and upgraded according to the change. This requires an effective system implementation methodology. In this paper, a methodology based on the multi-criteria similarity comparison of manufacturing processes is proposed. A newly introduced process is compared with existing ones based on the multi-criteria similarity, and candidates for software reuse are selected from stored modules according to the overall process characteristics. The proposed methodology has been tested for an electronics manufacturing company's manufacturing control system, and the result has been satisfactory in that it can save time and efforts for system implementation.

The Railroad Safety Act's regulation reads as follows. "The Minister of Construction and Transportation may qualify and authorize the product to guarantee performance and safety of parts, machine, and device used in Railway fields." Another regulation reads as follows."“The guidelines about targets, standards, and procedures of Quality and Authority in first provision are decided as Ministry of Construction and Transportation Decree." The software used in rail cars and facilities is considered as a railway product. Therefore, it is qualified and authorized for acquiring the safety of rail cars and facilities. The software businesses shall again a Quality and Authority for applying a software to the rail cars and facilities. This paper regulates some guidelines that are needed to develop a software. The procedures that a software developer performs are divided by plan, requirement, design, implementation, and maintenance. The procedures that a software verification person performs are classified by verification plan, requirement verification, design verification, implementation verification, testing verification, maintenance verification, and safety activity. The entire processes and detailed activities to develope and verify a software are described as new guidelines.

This paper describes the design and implementation of a PC(personal computer) based open architecture machine tool controller. The hardware of open architecture CNC has generally a motion control board on a PC for controlling a servo motor. But this paper describes open architecture hardware that consists of a PC, a counter board a DAC board and a DIO board only. This makes it easy to generate CNC software module in a hardware-independent way. The proposed open architecture CNC software runs on the MS-Windows NT. The paper describes a method of con-trolling servo motors using a real-time timer of MS-Windows NT and a commercial real-time operating system on the MS-Windows. NT. An open and reconfigurable software module is made up of an object and an API(application programming interface). Using the object and the API a new CNC system can be quickly configured to control dif-ferent machine tools. The proposed open architecture CNC system is applied to 4-axis lettering center.

Monitoring system is essential part in control system to monitor the circumstances of the industrial equipments. Color graphics is generally introduced in the monitoring system for the purpose of effective human interfaces. Hence, color graphic editor is under the implementation to draw graphic elements easily which are utilized in the monitoring situation. In this study, OOP(object oriented programming) is applied in the programming of the software. OOP enables systematic design of algorithm, easy management of the software and easy extension of additional functions. It is reported that the software is under the implementation. Therefore, preliminary structure of the software is briefly discussed in this paper.

This paper proposes a home control system architecture that have network configuration function. The proposed home control system architecture is implemented with partly hardware and software. For implementation of this system architecture, we developed ECONICS which is home automation controller. ECONICS consists of main board and communication modem. This communication modem supply the power line communication. The physical layer and the MAC layer software of EIA 709.1 standard protocol are implemented in communication modem. The upper layer software of EIA 709.1 standard protocol and home configuration software for home network installation, management, diagnostics, control and monitoring are implemented in main board of ECONICS. We verified the commercial feasibility of the proposed system through the home network configuration and operation. As a result, we have concluded that the proposed home control system architecture provides all the key function necessary to easily manage and control home network nodes.

As WSNs(Wireless Sensor Networks) are being deployed widely in diverse application areas, their management and maintenance become more important. Recent sensor node software takes modular software architectures in pursuit of flexible software management and energy efficient reprogramming. To realize an flexible and efficient modular architecture particularly on resource constrained mote-class sensor nodes that are implemented with MCUs(Micro-Controller Units) of a single address space. an appropriate module linking model is essential to resolve and bind the inter-module global symbols. This paper identifies a design space of module linking model and respectively their implementation frameworks. We then establish a taxonomy for module linking models by exploring the design space of module linking models. Finally, we suggest an implementation framework respectively for each module linking model in the taxonomy. We expect that this work lays the foundations for systematic innovation toward more flexible and efficient modular software architectures for WSNs.

본 논문은 소프트웨어를 재사용하기 위한 클래스 라이브러리 관리 시스템(CLMS: Class Library Management System)을 설계하고 구현에 관한 것이다. 통신 관련 소프트웨어의 특징은 소프트웨어가 방대하고, 다른 소프트웨어와 달리 개발이 완료되어도 끊임없이새로운 서비스를 수용해야 하며 개발 후 유지보수 및 신규 서비스의 확장 및 추가가 용이해야 한다는 것이다. 이러한 특징 때문에 소프트웨어 재사용은 생산성과 품질 향상에 기여할것이다. 클래스 라이브러리 관리 시스템은 객체지향 데이타베이스를 기반으로 클래스 등록기, 클래스 검색기, 클래스 항해기로 이루어져 있으며 원시 코드뿐만 아니라 SDL 설계 명세서도 재사용 할 수 있도록 고안되었다.
