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.

Recently, we meet with the various information by unordered or multi-dimensional in the information society. And we need to get ability of systematically arrange and use that. In general, human brain have the most effective result for the transmission of meaning when recognize the information by their own characteristic and imagination. It was decided by organize and easily express of get at the heart of the keyword and interrelation for take the information and represent own idea. It is the purpose of this paper to introduce the product designer for creativity get the radial thinking based on various information and can logically build the core keyword in the process of abstract the design concept by mind map and I increase understanding by a case study.

The purpose of this study is to explore the content hierarchy of ICT curriculum in elementary school. Korea Ministry of Education has been released the 2nd ICT curriculum by last year. Over the past few years, several studies have been focused on the problem of 1st curriculum. But there has been no study that tried to find the internal justification of computer subject matter. Also there has been different hierarchy each and every textbook. And, we explored a standards of selection and a principles of organization of computer subject matter. then applied it to the content hierarchy of 2nd ICT curriculum. We tried to find relations with the content hierarchy and the types of thinking learner use. We suggests that computer subject can be organized by hierarchy of content and learners experiences. It can be logically organized between different grade, horizontally organized between same grade.

This study analyzed the cause for mooring chain cut in a naval ship moored, in preparation for a typhoon approach, to a buoy in a shelter. The result of the analysis led to a very interesting fact. That is, while officers usually understood the cut results from the fact that the wind and the tide were stronger than what the mooring chain can hold, according to the study, it was analyzed the impact power at the point where the mooring chain and the ship's body met was a main factor in the cut. Also, it was confirmed that the analytic result of the study is more logical from the point of mathematical analysis and that the cut corresponds to what the then-witnesses stated about the situation.

The purpose of this paper is to investigate a possibility of applying multimethodological approach for solving a dilemma. The motivation of this attempt is that the two different approaches, the system dynamics and the theory of constraints, resemble each other in having mental models for describing the target system and using graphic tools for representing those mental models. After a brief discussion on the comparison of the two approaches, a combined method applying to the problem of dilemma is suggested. For an experimental example, the proposed approach is applied to the sales and finance conflict on an inventory issue. The study shows that the suggested approach is able to complement each other's drawbacks. Especially constructing a stock-and-flow model and implementing a computer simulation would be very useful for quantifying the system's behavior which is hardly tracked down when applying the theory of constraints alone.

안전성 분석 활동으로 널리 쓰이는 폴트 트리 분석은 그 원인들의 관계를 논리게이트로 표현하고 원인을 자연어로 설명한다. 폴트 트리에서 자연어를 사용하여 사고의 원인을 나타내는 것은 폴트 트리 자체의 검증뿐만 아니라, 동일한 대상의 시스템 명세에도 적용하기에 어려운 부분이다. 본 논문에서는 폴트 트리를 상태 차트로 변환하는 방법을 제안 하였으며, 상태차트로 변환된 폴트 트리를 상태차트로 명세 된 시스템의 기능적 요구사항과 결합함으로써 상태차트로 표현된 기능 명세가 안전성 분석활동을 통해 얻은 폴트 트리에 순응 되는지 여부를 볼 수 있었고, 폴트 트리에서의 분석 대상인 사고가 발생하기 까지를 추적할 수 있었다.

The purpose of this study is to explore whether pre-service teachers majoring in earth science improve their perception of computational thinking through STEAM classes focused on engineering-based wave power plants. The STEAM class involved designing the most efficient wave power plant model. The survey on computational thinking practices, developed from previous research, was administered to 15 Earth science pre-service teachers to gauge their understanding of computational thinking. Each group developed an efficient wave power plant model based on the scientific principal of turbine operation using waves. The activities included problem recognition (problem solving), coding (coding and programming), creating a wave power plant model using a 3D printer (design and create model), and evaluating the output to correct errors (debugging). The pre-service teachers showed a high level of recognition of computational thinking practices, particularly in "logical thinking," with the top five practices out of 14 averaging five points each. However, participants lacked a clear understanding of certain computational thinking practices such as abstraction, problem decomposition, and using bid data, with their comprehension of these decreasing after the STEAM lesson. Although there was a significant reduction in the misconception that computational thinking is "playing online games" (from 4.06 to 0.86), some participants still equated it with "thinking like a computer" and "using a computer to do calculations". The study found slight improvements in "problem solving" (3.73 to 4.33), "pattern recognition" (3.53 to 3.66), and "best tool selection" (4.26 to 4.66). To enhance computational thinking skills, a practice-oriented curriculum should be offered. Additional STEAM classes on diverse topics could lead to a significant improvement in computational thinking practices. Therefore, establishing an educational curriculum for multisituational learning is essential.

This study is to estimate the possibility of accident in chemical plants from the analysis of system component which affects the occurrence of top event. Among the various risk assessment techniques, the Fault Tree Analysis which approaches deductively on the route of accident development was used in this study. By gate-by-gate method and minimal cut set, the qualitative and quantitative risk assessment for hazards in plants was performed. The probability of occurrence and frequency of top event was calculated from failure or reliability data of system components at stage of the quantitative risk assessment. In conclusion, the probability of accident was estimated according to logic pattern based on the Fault Tree Analysis. And the failure path which mostly influences on the occurrence of top event was found from Importance Analysis.
