The purpose of this study is to analyze the effects of computational thinking class using ARCS model to increase students' learning motivation. Then, this study designed the detailed instruction strategy according to each motivation factor(Attention, Relevance, Confidence, Satisfaction) of ARCS through the previous study on computational thinking education and ARCS model. The results of the ARCS test were compared between the experimental group to which the ARCS model was applied and the control group to which the general class was conducted. As a result, students in the experimental group showed significantly higher motivation for learning about computational thinking. In particular, the learning motivation of computer-related majors was significantly higher than that of the control group. In addition, majors were found to have high relevance(R) and non-majors had high satisfaction(S). Therefore, based on these findings, this study suggests an improvement for effective computational thinking class in liberal arts education.

Recently, as SW education has been emphasized in college, interest in Computing Thinking (CT) class at the liberal level has increased. In order to effectively educate students, various methods of teaching and learning are required to reduce the burden on CT education and motivation of students. The purpose of this study is to design teaching and learning using ARCS model to improve learners' learning motivation and learning achievement in CT course as liberal arts education. In this study, the learning elements of CT were selected based on previous research on the characteristics of education in the liberal arts education of the university and analysis of the CT content. In addition, Keller 's ARCS learning motive model was selected to match the instructional tactics according to the motivational factors of Attention, Relevance, Confidence, and Satisfaction. In order to effectively teach these CT contents, detailed strategies based on the ARCS model were designed and presented weekly.

When the circuit-breaker switches off, an electric arc is established between the contacts. It is very important to understand the arc characteristics for the design of a circuit breaker. This article describes the theoretical analysis of the arc characteristics by means of energy integral method when convection dominated low current arcs are produced in the dual-airflow nozzle of a model interrupter. In order to investigate the arc radius, the average electric field strength and the arc voltage, the arc column is divided into two regions, and then the energy conservation equation is applied to the arc in each region together with the axial cold flow mass flux function, steady-state mass balance equation and Ohm's law. The results show good agreements with those of other researchers.

Motivation is a generative power of making learning interesting and sustaining learning for students. Textbooks are important tools in carrying out lessons. And it is meaningful to analyze how textbooks motivate learning. This study is to analyze components of motivation in learning of the 7th grade middle school science textbooks. Keller's ARCS model was used for the analysis. The result of the study is as follows. First, the eight textbooks had various components from A1 to R3. Second, analyzing textbooks by parts of the textbooks, the body had the most motivation strategies and the next was the introduction, lastly the finishing part. Third, the most frequently used strategy on the attention factor is A1. And the most frequently used strategy in the relevance factor is R3.

The model interrupters of $SF_6$ gas electromagnetic contactor whose ratings are 7.2kV, 4.0kA have been designed and manufactured on the basis of theoretical and computational analysis for its development. The eddy current analysis, the magnetic field analysis and the calculation of the rotational force on arcs have been conducted using FLUX2D package. The short circuit current interrupting tests have been conducted for the model interrupters using the simplified synthetic testing facility in KERI. The results show that the model interrupters have sufficient interrupting capability and the new design concept is prefer for good interrupting performance.

Purpose: The purpose of this study was to develop a guide book on safety education for teachers to use in education classes for elementary school students. Methods: Dick & Carey's teaching model and Keller's ARCS theory were used in the development of this guide book. Results: This guide book was developed for lower grade (1st$\sim$3rd) and higher grade (4th$\sim$6th) elementary school students. The content consisted of subjects, worksheets, content for teachers, statistical data, case studies, and a safety letter to the parents. The 10 subjects were as follows: "Importance of injury prevention", "Safety at home", "Accident prevention at school", "Violence prevention", "Vehicles safety", "Water safety", "Prevention of Fires & Burns", "Safety of Toys & home supplies", "Safety in Sports & Recreation activity", "Prevention of injury caused by animals". Statistical data was presented by graphs and case studies were presented of cases of real occurrences of accidents. Worksheets contain various activities for students. Safety letters were composed for each student's parents. Conclusion: This guide book presents effective material for safety education classes in elementary school and the authors hope it will be widely used in elementary schools.

Purpose: The purpose of this study was to develop a guidebook for teachers about coping behavior education in emergency situations for elementary school students. Method: Dick and Carey's teaching model (1996) and Keller's ARCS theory (1985) was applied to develop this guidebook. Results: The contents consist of subjects, reference materials for teachers, a case study, and worksheets for students. The contents of the 5 units are as follows: 1)Identifying a dangerous situation around the school area and in school, 2)Coping tips in dangerous situations that can occur at school, 3)Prevention and coping method of sexual violence, 4)Coping method for natural disasters, and 5)First aid in emergency situations. The presented case study was a real case scenario and the worksheets contained various activities initiated by students. Conclusions: This guidebook can be an effective tool in coping education classes for emergency situations at elementary schools. The goal of the guideline book is reach as many elementary schools as possible.

Purpose: The purpose of this study was to develop and evaluate the effects of a safety education injury prevention program in elementary school students. Methods: To develop the safety education program, Dick & Carey's teaching model and Keller's ARCS theory were applied. A safety education programs was developed for lower grade students (1st-3rd) and for higher grade students (4th-6th). To evaluate the effect of the safety education program, a pre-post test questionnaire was used with experimental and control groups. The participants were 238 (119 in the experimental group, 119 in the control group) lower (3th) grade and 296 (148 in the experimental group, 148 in the control group) higher (5th) grade elementary school students. For students in each experimental group, safety education was provided for 40 min once a week for 10 weeks. Results: There were significant differences in the level of injury prevention knowledge, attitude, and practice between the experimental group and control group in both the lower and higher grade elementary students. Conclusion: The findings of this study indicate that safety education is an effective nursing intervention to improve injury prevention knowledge, attitude, and practice in elementary school students.
