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.

For high-quality software development, it is necessary to detect and fix the defects inserted. If defect management activities are not properly performed, it will lead to the project delay and project failure due to rework. Therefore, organizations need to establish defect management process and institutionalize it. Process standard models handle defect management in the area of project monitoring and control. However, small organizations experience difficulties in implementing and applying defect management process in a real situation. In this paper, we propose a defect management process for small organization which is designed in accordance with the characteristics of a small projects such as few participants and short development period. The proposed defect management process will be based on a tool chain with open source software such as Redmine, Subversion, Maven, Jenkins that support a defect management process and SW Visualization in systematic way. We also proposed a way of constructing defect database and various methods of analyzing and controlling defect data based on it. In an effort to prove the effectiveness of the proposed process, we applied the process and tool chain to a small organization.

This paper deals with inter-relationship change of women's university students on the process of SW development project using social collaboration tool. Inter-relationship is one of the basic vocational competency in NCS(National Competency Standards) of Korea. We redesigned the curriculum of "Software Engineering" subject for this study and composed the project teams of students to develop software. The details of inter-relationship are satisfaction, communication, faith, friendliness, sensitivity, openness and consideration. From the result of this study, faith, openness and consideration have positive effect but satisfaction, communication, friendliness and sensitivity have no meaningful effect. The surveys were conducted in the beginning of semester and the same surveys were conducted again in the end of semester. The results were verified by paired t-test with SPSS 18.0. It is significant that the using of social collaboration tool for team project has positive effect on inter-relationship change, especially faith of women's university students. This study has some limitations for generalization but has meaning as new trial to enlarge the basic vocational competency of students in major subject, "Software Engineering". We expect new study for inter-relationship change of students to evaluate generality based on the proposed method in this paper.

In this paper, as a liberal arts course for non-major students, a case study of recurrent neural network SW practice, which is essential for designing a basic recurrent neural network subject curriculum, was developed. The developed SW practice case focused on understanding the operation principle of the recurrent neural network, and used a spreadsheet to check the entire visualized operation process. The developed recurrent neural network practice case consisted of creating supervised text completion training data, implementing the input layer, hidden layer, state layer (context node), and output layer in sequence, and testing the performance of the recurrent neural network on text data. The recurrent neural network practice case developed in this paper automatically completes words with various numbers of characters. Using the proposed recurrent neural network practice case, it is possible to create an artificial intelligence SW practice case that automatically completes by expanding the maximum number of characters constituting Korean or English words in various ways. Therefore, it can be said that the utilization of this case of basic practice of recurrent neural network is high.
