With the recent wide adoption of Linux in the fields of IoT, embedded, mobile, desktop and server industries, the importances of understanding the Linux system architecture as well as customizing the Linux system are increasing very steeply. Accordingly, the capabilities of building every component of Linux system from source code files have been important. The LFS (Linux From Scratch) site[1] guides the steps of building the basic Linux system from source files. The steps consist of build host preparation step, temporary system building step, final system building step, and system configuration and boot preparation step. However, the underlying concepts behind the steps used in building LFS are difficult to understand, particularly to the beginner. This paper analyzes the LFS build steps and reveal the core build concepts and principles used in each step. Additionally, this paper shows the measured package build times obtained from our build experience.

TRIZ, the theory of inventive problem solving, is widely used not only in traditional engineering fields such as mechanical, electrical, and electronic engineering but also in IT field and generated good results. Therefore, recently many universities have opened TRIZ as a regular course. Especially, 40 inventive principles of TRIZ are not only creative thinking tools that beginners can learn relatively easily but also very effective problem solving tools, but it is not that easy to utilize it properly for solving real problems as you think. In order to use inventive principles as powerful tools for creative problem solving, it is important to educate learners to use it repeatedly through stimulating their interest about the inventive principles. So, in this paper, we introduce various inventive principles hidden in the cards that can be easily accessible in everyday life, and propose how to educate learners to evoke their interest in the inventive principles through making cards by utilizing the inventive principles.

To automate nuclear design works which are time-consuming and man-power intensive, Innovative Design Processor ($IDP^{TM}$) is being developed. Two basic principles of IDP are the document-oriented design and the web-based design. The document-oriented design is that, if the designer writes a design document called active document and feeds it to a special program which has a robust parser, the finai document with complete analysis, table and plots is made automatically. The active documents can be written with ordinary HTML/XML editors or created automatically on the web, which is another framework of IDP. Using the proper mix-up of server side and client side programming under the LAMP (Linux/Apache/MySQL/PHP) environment, the design process on the web is modeled as a design wizard style so that even a novice designer makes the design document easily.

In this paper, we propose a virtual violin implementation using the detection of bowing and finger dropping position from the estimated finger tip and finger board information with the 3D image data from a Kinect. Violin finger board pattern and depth information are extracted from the color image and depth image to detect the touch event on the violin finger board and to identify the touched position. Final decision of activated musical alphabet is carried out with the finger drop position and bowing information. Our virtual violin uses PC MIDI to output synthesized violin sound. The experimental results showed that the proposed method can detect finger drop position and bowing detection with high accuracy. Virtual violin can be utilized for the easy and convenient interface for a beginner to learn playing violin with the PC-based learning software.

As the electronic processing of music gradually is developed, there has been growing interest in automatical input of music. As a result, various researches which input music in the computer has been studied. However, previous studies have drawbacks that only the experts can do it. In other words, if beginners would like to use traditional production program of music scores than prior knowledge is required. To resolve this, we propose system painting music scores automatically using a bandwidth of soundsource, after extracting the voice sounds created by amateurs. The System provides amateurs with convenience so that they can compose. As well as, the System provides the ability to play music that produced by the computer. By using the system, amateurs can compose using voice and simple system handling. And, they can make a music that plays desired instruments.

CFD analysis is an analytical technique that applies a computer to the design and development of products across the entire industry for heat or fluid flow. This technology is used to shorten the development period and reduce costs through computerized simulation. However, the software used for CFD analysis is now required to use expensive foreign software. The Opensource CFD analysis software used in the proposed system has reliability of commercial CFD analysis software and has various user groups. However, for users who have expert knowledge, Opensource CFD software which supports only text interface environment, We have developed an environment that enables the construction of a CFD analysis environment for beginners as well as professionals. In addition, the proposed system supports the pre-processing (design and meshing) environment for CFD analysis and the environment for post-processing (result analysis & visualization), enabling the integrated CFD analysis process in one platform.

In the SW education of non-majors who encounter liberal arts education experience difficulties in the SW development environment and understanding they encounter for the first time, relevance to their major, and convergence thinking ability. In order to compensate for the difficulties of non-major learners in liberal arts education, a relatively easily accessible software was used to utilize a demonstration-oriented model that can be applied to beginners in SW education. In order to understand the logical flow of applications and problem solving used in real life, we proposed a convergence SW teaching method that combines repeated implementation through demonstration by the instructor and imitation of the learner, and learning indicators to increase the learning satisfaction and achievement of the learner. In the experiment applying the teaching and learning method proposed in this paper, meaningful results were shown when evaluating the learning effect, academic achievement, learning satisfaction, and teaching and learning method aspects of SW education.
