본 연구의 목적은 ARCS 모형을 적용한 컴퓨팅 사고력 수업에 대한 효과를 분석하는 것이다. 이에 본 연구에서는 컴퓨팅 사고력 교육과 ARCS 모델에 대한 선행연구를 통해 ARCS의 각 동기요소(주의집중(A), 관련성(R), 자신감(C), 만족감(S))에 따른 세부 수업 전략을 설계하였다. 그리고 ARCS 모델을 적용한 실험반과 일반적인 수업을 실시한 비교반의 학습동기 검사결과를 비교하였다. 그 결과, 실험반의 학생들이 컴퓨팅 사고력 수업에 대한 학습동기가 유의미하게 높게 나타났다. 특히 컴퓨터 전공 관련 학생들의 학습 동기는 비교반에 비해 현저히 높게 나타났으며 전공 학생들은 관련성(R) 영역이, 비전공 학생들은 만족감(S) 영역이 높게 나타났다. 따라서 본 연구에서는 이러한 결과를 토대로 향후 효과적인 교양 교육에서의 컴퓨팅 사고력 수업에 대한 개선을 제안하였다.

최근 대학에서도 SW 교육이 강조됨에 따라, 교양 수준의 컴퓨팅 사고력(CT)수업에 대한 관심이 높아졌다. 이에 효과적인 교양 교육을 위해 학생들의 CT 교육에 대한 부담감을 줄이고 학습동기를 높이기 위한 다양한 교수학습방법이 요구되고 있다. 이에 본 연구의 목적은 필수 교양으로써의 CT 교과목에서 학습자들의 학습동기와 학습 성취도를 향상시키기 위한 ARCS 모형을 적용한 교수학습을 설계하는 것이다. 이를 위해 본 연구에서는 대학의 교양 교육에서의 교육의 특성에 대한 선행연구와 CT 내용 요소 분석을 바탕으로 CT의 학습 요소를 선정하였다. 또한, Keller의 ARCS 학습동기 모형의 주의집중(Attention), 관련성(Relevance), 자신감(Confidence), 만족감(Satisfaction)의 각 동기요소들에 따른 수업 전술을 본 과정에 맞도록 선별하였다. 결국, 본 연구에서는 이러한 CT 내용들을 효과적으로 가르치기 위해 ARCS 모형 기반의 세부 전략을 주차별로 설계하여 제시하였다.

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.

동기는 학생들의 흥미를 유발시키고 학습을 지속시켜 줄 수 있는 가장 큰 원동력이 며, 교과서에서 이러한 학습 동기를 어떠한 방법으로 유발시키고 있는지를 살펴보는 일은 유의미한 분석이 될 것이다. 본 연구는 2007 개정 7학년 8종 교과서가 어떠한 유형들로 학생들의 동기유발을 촉진시키고 있는지를 Keller의 ARCS 모형을 통해 적용하여 보았다. 본 연구의 결과는 다음과 같다. 첫째, 2007 개정 8종 교과서별로 동기유발 요소를 분석한 결과 각각의 교과서에 A1~R3까지의 분석 요소들을 영역별로 다양하게 사용하였다. 둘째, 교과서의 영역별로는 본시 학습 부분에서 가장 많은 동기유발 요소들이 사용되었고 그 다음으로는 도입부, 단원 마무리 순으로 동기유발 요소들이 사용 되었다. 셋째, 교과서를 Keller의 ARCS 모형의 동기유발 요소별로 분석한 결과 주의집중(A) 요소에서는 교과서의 모든 영역에서 A1(지각적 각성) 전략과 관련성(R) 요소에서는 R3(친밀성) 전략을 가장 많이 사용하였다.

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 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.
