Software product-lines methodology is the software development paradigm to build the target system by customizing the variable part of software assets according to requirements. To attain this, the commonalities and variabilities of the system family should be modeled explicitly at early stage. Although the researches on general software product-lines are active, the researches on component-based real-time embedded software product-lines are rather inactive. In this paper a code generation system to support the functional variabilities via feature model and generate the code for synchronization via state model is proposed to increase the productivity of the development of the real-time embedded software product-lines.

The Web has unique characteristics that distinguish it from products or software, so it is necessary to expand the concept of usability to include not only cognitive convenience but also emotional aspects and culture. Unlike software created with a clear intention by a single author or group, the Web is created by various authors with various purposes, so it requires various interactions between users and the system. Compared to existing software with few changes for system maintenance and updates, the Web is a dynamic system that continuously grows and changes. Unlike the relatively homogeneous and limited user group of software, the Web is used by users with various backgrounds and levels, making it difficult to provide unified training or control for the system. Since usability on the Web depends on how accurately and quickly users can access the information they want and how much aesthetic satisfaction and enjoyment they can provide, usability evaluations should be conducted in a different way from traditional software. Due to the diverse and constantly changing characteristics of the web from the basic environment to the end user, it is not desirable to apply software development principles and processes to the development of websites. Unlike the software environment, the Web does not have a defined user base, and unlike software, the tasks performed by users do not have a starting, middle, and ending stage, and they behave differently depending on their preferences. In this paper, we aim to provide an overview of web standardization in dynamic web environments.

AUTOSAR, a standard software platform for automotive, has been developed to manage software complexity and improve software reuseability. However Automated and standardized testing is needed to improve reliability and reduce time and effort on testing. Fundamental functionality of AUTOSAR RTE and basic software modules is guaranteed by using an AUTOSAR tool, but application software components have to be tested thoroughly. In this paper, we suggest a test system for the AUTOSAR software component using TTCN-3, a standardized testing language. Test execution system and test cases for the software component are generated automatically from AUTOSAR XML containing software design information. With the proposed testing techniques we can reduce time and effort to build the testing system.

Software based fault tolerance techniques are designed to allow a system to tolerate software faults in the system. Fault tolerance techniques are divided into two groups : software based fault tolerance techniques and hardware based fault tolerance techniques. We need a proper design method according to characteristics of the system. In this paper, the concepts of software based fault tolerance techniques for Dual Flight Control Computer are described. For software based fault tolerance design, we classified software failure, designed a way for failure detection and the way of recovery. Eventually the effectiveness of software based fault tolerance techniques was verified through the Software Test Environment(STE).

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.

Recently Software Industry has tended to enhance the productivity and quality with using the software architecture in software development and administration. The research of software component technique and software development methodology are just doing and making many applications. The software architecture is considered as the essential element for analyzing and maintaining the entire structure with organizing the software into components and describing the relations with connectors. The software modeling methodology that we propose is generating Happy Work Language describing the software structure with the modeling tool as Happy Work. We can use System Context Diagram, Component Diagram, Component Sequence Diagram, and they are composed of four Elements as Users, Systems, Components, Connectors.

This study involves an experiment for the cognitive experiment design and the human reliability in software engineering. Its overall objectives are to analyze common-cause human domain error and reliability in human-software interaction. A laboratory study was performed to analyze software engineers' task behavior in software production and to identify software design factors contributing to the effects in common cause failure redundancy. Common-cause model and its function were developed, then the main experiment using programming experts was conducted in order to define a new cognitive paradigm, in the aspects of identification, pattern recognition, and behavior domain for human reliability and quality control in software development. The results and analytical procedures developed in this research can be applied to reliability improvement and cost reduction in software development for many applications. Results are also expected to provide guidelines for software engineering quality control and for more effective design of human-software interface system.

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.
