Though the studies on object-oriented software design which software component corresponds to phrases appearing in sentences of natural language have been going on, the design methodology has not been clearly set up yet. In this paper, the module structure of good quality was found not only by nouns that indicate class of object but also by subdividing sentences. I also suggested objected-oriented methodology observing the interdependency between objects and their relationships, and assessed the control problem of lift as an example.

With increasing interest in 3D printing, the interest in the 3D modelling training that should precede the 3D printing is increasing. However, the existing 3D modelling software is developed mostly by foreign brands. Thus, the interfaces are all in English. 3D modelling software training for Korean novices who are not familiar with these terms has constraints. This study aims to explore what to consider when developing a Korean model for 3D modelling educational software for 3D printing in the face of such reality. For this goal, after having novices with no experience in 3D modeling to perform a house building task using either 12D Design or Tinker CAD, we conducted a survey. It was found in the result that more users favored Tinker CAD over 123D Design, and the errors involved while working with the Tinker CAD were less than those with the 123D Design, and the ratio of people who completed the task with the Tinker CAD was higher than that with the 123D Design. In general discussion, an introductory level educational 3D modeling software development is proposed which utilize characteristics of Tinker CAD (easy modelling is possible by three-dimensional figures) and web-based method. Also, a beginner/intermediate level educational 3D modeling software development is proposed which utilize characteristics of 123D Design (with finer measurement manipulations and figure alignment) and Windows-based method.

Purpose: The purpose of this study is to design the curriculum of Basic College Software Programming to develop creative and logical-thinking. This course is guided by algorithmic thinking and logical thinking that can be solved by computing for problem-solving, and it helps to develop by software through basic programming education. Through the stage of problem analysis, abstraction, algorithm, data structure, and algorithm implementation, the curriculum is designed to help learners experience algorithm problem-solving in various areas to develop diffusion thinking. For Learners aim to achieve the balanced development of divergent and convergent-thinking needed in their creative problem-solving skills. Research design, data and methodology: This study is to design a basic software education for improving algorithm-thinking for non-major. The curriculum designed in this paper is necessary to non-majors students who have completed the 'Creative Thinking and Coding Course' Design Thinking based are targeted. For this, contents were extracted through advanced research analysis at home and abroad, and experts in computer education, computer engineering, SW education, and education were surveyed in the form of quasi-openness. Results: In this study, based on ADD Thinking's algorithm thinking, we divided the unit college majors into five groups so that students of each major could accomplish the goal of "the ability to internalize their own ideas into computing," and extracted and designed different content areas, content elements and sub-components from each group. Through three expert surveys, we established a strategy for characterization by demand analysis and major/textbook category and verified the appropriateness of the design direction to ensure that the subjects and contents of the curriculum are appropriate for each family in order to improve algorithm-thinking. Conclusions: This study helps develop software by enhancing the ability of students who practice various subjects and exercises to explore creative expressions in various areas, such as 'how to think like a computer' that can implement and execute their ideas in computing. And it helps increase the ability to think logical and algorithmic computing based on creative solutions, improving problem-solving ability based on computing thinking and fundamental understanding of computer coding and development of logical thinking ability through programming.

Due to increase in software-based new technologies, software developers are being required to creative problem solving. Especially, for a successful business change of software developers into a new industrial field, software analysis phase and design phase are important and it is an important task to strengthen these competences. In this study, two independent researches were conducted. First, a survey with 300 software developers was conducted and it was explored that uniform thinking of software developers caused by application of "standard software development methodology" made it difficult to approach creative problem solving. Based on this finding, the influences of 9 competences of computational thinking on software developers were analyzed after selecting 111 software developers with over 10 years of experience in the IT industry. As a result, it was revealed that abstraction was an important competence. The study finding demonstrates that software developers recognized design phase as the most important thing and abstraction of CT is the basics of other competences.

Recently, the application area of an embedded software become larger and larger rapidly due to the development of the wire and wireless communication, the expansion of the digital information device and the convergence of the digital devices and emphasize the effort of the development of more complete software. As a consequence, the importance of the software test process was raised to discover the defects of the software early and improve the quality of an embedded software. However there was no test process model for applying the embedded software which is required the highly precision and the real-time process. In this paper, therefore, we propose the design procedure and case study for the test maturity model of an embedded software(Emb-TMM) which reflects the characteristics of the embedded software and test process. for this, we suggest the three category of the proposed procedure which consists of the selection of the reference model and the derivation of the area, the categorization of the area level, and design model. Then we suggest the case study how the proposed procedure can be applied to the development of an embedded software actually.

Industrial ventilation is a crucial engineering measure to protect workers from hazardous airborne contaminants. Designing a ventilation system is not an easy task. To solve this problem, many U. S. computer programs and softwares have been developed. In Korea, asoftware, called as VPMC, was developed by Korea Industrial Safety Corporation. But VPMC could not stand alone since it can be used to design not a hood, but a ventilation system. In this research, therefore, a preprocessing software was developed. It can be used to design general ventilation system, canopy hood, open surface tank hood. The program was written in Microsoft Visual Basic. In near future, this software will be incorporated into a total package software which can be used to design a whole ventilation system.

This paper presents a design technique of steel structures subjected to static and dynamic loadings using practical nonlinear inelastic analysis software. The beam-column approach using the stability functions and the plastic hinge concept enables the software to suitably predict second-order effects and inelastic behavior of beam-columns. For dynamic analysis. the incremental from of the equation of motion is solved by the use of a step-by-step numerical integration procedure in which the assumption of constant acceleration over a small time step is employed. The accuracy of the analysis program is validated using the results of ABAQUS program and experimental tests. A user-friendly graphic interface of the software is developed to facilitate the modeling process and result interpretation of the problem. A design example of large span bridge is presented to detail the direct design process using the practical advanced analysis software.
