This study was performed in order to find implications for further activating the reading discussion program by conducting a Havruta-based reading discussion program for elementary school students in the library, by measuring and analyzing the effect on the participants. The results of the study are as follows: First, as a result of comparative analysis between the pre- and post-scores on the effectiveness of the Havruta reading discussion program, it was found that the average score of the post-test was high. Second, as a result of analyzing the differences in the changes in the results of the pre-survey compared to the post-survey according to the general characteristics of the participants, it was found that there were significant differences in the characteristics of 'interest in reading' for the 'critical thinking ability' factor, the characteristics of 'average monthly reading capacity' for the 'critical thinking ability' factor, the characteristics of 'academic performance' for the 'research ability' factor, and the characteristics of 'gender', 'academic performance', and 'interest in reading' for the 'persuasive ability' factor. Third, as a result of analyzing how the effects of the Havruta reading discussion program are affected by the constituent factors of reading and discussion ability, it was found that the factors 'critical reading ability' and 'critical thinking ability' had an effect. As a result, it was identified that there are effects and advantages of the Havruta-based reading discussion program in the library.

해상교통관제 업무는 선박사고 발생 위험에 대한 부담감 및 교대근무 등 불규칙한 근무형태로 인해 스트레스가 많은 직종이다. 특히나 관제 업무는 고도의 주의와 예측능력을 요구하는 업무로 이를 저해하는 인적요인 분석 및 관리 필요성이 절실한 분야지만 관제사의 직무스트레스에 관한 연구가 전무한 실정이다. 관제사의 스트레스로 인한 피로증상은 관제업무수행에 필요한 인지능력이나 의사결정 능력을 저하시킬 수 있고 이로 인해 업무수행에 차질을 빚을 경우 안전사고로 이어질 수 있는 위험이 존재한다. 그러므로 안전과 직결된 관제사의 스트레스는 과학적으로 연구되어야 하며 제도적 마련과 더불어 체계적 관리가 필요할 것이다. 이에 본 연구에서는 한국인 직무스트레스 측정도구를 이용하여 관제사의 직무 스트레스 수준을 파악하고 직무스트레스 관리의 필요성에 대하여 제고해보고자 한다.

최근 국내외에서 소프트웨어 교육의 중요성이 강조되고 있다. 2015년 개정 교육과정에서도 초 중등생들의 컴퓨팅사고력 계발에 관심이 집중되면서 초 중등학생들을 대상으로 코딩교육이 진행되고 있다. 컴퓨팅사고력 증진을 위해 그 핵심요소인 추상화와 자동화 능력을 신장시킬 여러 방법들이 연구되고 있다. 본 연구에서는 추상화 능력에 대해 교육심리 측면에서 학생들의 프로그래밍 능력 특성을 파악한 후, 컴퓨팅 사고력 계발에 도움을 주고자 한다. 이를 위해 일반계 고등학생들을 대상으로 파이썬 프로그래밍 교육을 보다 용이하게 진행하기 위하여 러플(RUR-PLE) 프로그래밍을 한 학기동안 학습한 후, 학생들의 추상적 사고수준이 프로그램을 이해하는데 어떻게 영향을 미치며 성별 간에 어떤 차이를 가지는지를 분석한다.

This research is designed to analyze the metacognitive thinking that mathematically gifted elementary students use to solve problems, study the effects of the metacognitive function on the problem-solving process, and finally, present how to activate their metacognitive thinking. Research conclusions can be summarized as follows: First, the students went through three main pathways such as ARE, RE, and AERE, in the metacognitive thinking process. Second, different metacognitive pathways were applied, depending on the degree of problem difficulty. Third, even though students who solved the problems through the same pathway applied the same metacognitive thinking, they produced different results, depending on their capability in metacognition. Fourth, students who were well aware of metacognitive knowledge and competent in metacognitive regulation and evaluation, more effectively controlled problem-solving processes. And we gave 3 suggestions to activate their metacognitive thinking.

The purpose of this study is to deduce improvement plan through analysis of the type and characteristics of traffic accidents caused by elderly drivers, and to establish the traffic safety policies for the elderly drivers. The analyzed result of road traffic accident situation are as follows. Firstly, Traffic accidents caused by elderly drivers were frequent on local roads of poor traffic safety facilities such as lighting. Secondly, The most frequent time zone of Traffic accidents caused by elderly drivers was 18:00 to 20:00, this time zone was mainly darkened. Thirdly, Traffic accidents are often caused by lack of attention occurred by no implementation of safe driving. Institutional Improvement of cosideration for elderly drivers and Traffic Safety Facilities maintenance considering regional particularities is needed for reducing traffic accidents and the safety of our society. Their driving skills of elderly drivers should test themselves constantly, and elderly drivers must hold down driving yourself using the alternative transportation.

The purpose of this study is to investigate the effects of Android application programming education to control Arduino using App Inventor on industrial high school students' creative and integrative thinking ability. We developed an instructional content based on integrative learning and creative problem-solving model and taught a class on it. The result of this study showed that there was a significant improvement in divergent thinking and motivation items among the sub elements of creative problem solving. In addition, students' survey on the integrated thinking has shown that many students think that they could design an IoT system applied to everyday life based on the knowledge they have learned in this class. Therefore, it can be confirmed that physical computing education using App Inventor and Arduino has a positive effect on students' creative and integrative thinking ability.

This research was planned to analyze the students' science writing tendencies according to the level of meta-cognition for using as materials of selection of gifted students. To get results, meta-cognition writing tests which measured critical thinking ability and problem solving ability were developed, and the students' the level of meta-cognition was measured. Thereafter We analyzed the students' science writing tendencies in accordance with the level of meta-cognition through the science writing with meta-cognition task(the main theme are expectation; explanation; claim; criticism; imagination), and found out the students' ability of science writing was different with the level of meta-cognition. Students with the low level meta-cognition did not represent their thinking well, but students with the high level meta-cognition were try to upgrade their writing through highly concentration and perceiving theirs writing mistakes. As this results, science writing is useful as materials of selection of gifted students.

The goal of this paper is to seek an educational method that can cause some communicational improvements to petty officer majoring students through listing and utilizing the academic vocabulary. The academic vocabulary has been listed by using three major steps. The first, the academic vocabulary is needed to extract from the studies based on this field in past 3 years. Second, the academic vocabulary for petty officers is required to compare with high school level of the academic vocabulary. For the last, the academic vocabulary is demanded to be listed for teaching petty officer majoring students. The signification of the academic vocabulary in this study is limited by focusing on the educational skills for writing in petty officer majors. This study presents a way to develop the communicational abilities through using the academic vocabulary into the collaborative learning. For the conclusion, this study presents its limits and further directions.

The purpose of this study was to develop instructional programs for 10th graders to facilitate their creative thinking abilities and understanding concerning the scale of the Solar System. The programs were based on four major themes and composed of eight lessons which dealt with the relative scale of the Solar System. The programs were applied to 155 students at G high school in Gumi City. The results showed that the programs were helpful to students in that they facilitated easier understanding of the relative sizes of planets within the solar system as well as creative thinking abilities including divergent thinking and convergent thinking.

본 연구는 교통사고 심각도와 관련된 중요변수를 찾고 이들 변수를 바탕으로 신경망, Decision Tree, 로지스틱 회귀분석을 이용하여 사고 심각도 분류 예측모형을 추정하였다. 다수의 범주형 변수로 이루어진 교통사고 통계원표상의 설명변수 들로부터 사고 심각도 변화에 영향력 있는 변수 선택을 위하여 독립성 검정을 위한 $x^2$ test와 Decision Tree를 이용하였고, 선택된 변수들은 신경망과 로지스틱 회귀분석의 기초로 이용되었다. 분석결과 세가지기법간에 분류정확도에는 유의한 차이가 없는 것으로 나타났다. 그러나 Decision Tree가 설명변수 선택능력과 분석수행시간, 사고 심각도 결정요인 식별의 용이함 측면에서 범주형 종속변수인 사고 심각도의 분석에 적합한 것으로 보이며 사고 심각도에는 보호장구가 가장 큰 영향을 미치는 것으로 재입증되었다.
