In this study, we established the process for collecting and utilizing video scripts of disaster site based on public-private partnerships. It is for the purpose of actively utilizing private capabilities in disaster management, and quickly sharing video scripts to identify field conditions. Based on the experience of actual operation of public-private partnerships system in the event of typhoon in 2019, we also derived implications for continuous operation of the process. Results are meaningful in that the government established the process for collecting and utilizing video scripts through public-private partnerships during the initial disaster response phase. And we also confirmed the possibility of spreading positive perception of disaster management organizations. However, there is a limit to the actualization and practical use of performance as an experimental pilot operation in the R&D stage. In addition, for continuous operation of the system, it is necessary to prepare institutional support measures such as organization, infrastructure for operating, programs of education and training, and policy making.

As the 4th industrial revolution has progressed in recent years, the importance of robot education in elementary school education is increasing. In this paper, I suggested robot education framework to consider conceptual understanding and learning activities based on the 2014, 2015 KAIE software education standard curriculum for elementary school. The framework is reconstructed the 7 stages, In order to generalize the standardized model of the software curriculum, the achievement criteria should be prepared according to the content system of the curriculum considering the conceptual understanding and learning activities proposed in this paper, and if the educational contents are developed and utilized, it is expected to contribute to the activation of robot education in addition to elementary school software education.

Currently computer education has been emphasized improving thinking skill instead of practical education of applied software. There are various studies that are to teach algorithm with visualization learning materials or activitives-centered unplugged class. However, algorithm classes for elementary school have various difficulties. One of the reasons is insufficient learning materials and teaching methods. Therefore we designed a activities-centered algorithm class for elementary school students. We hope this study will contribute to the study of algorithm classes for improving kids' thinking skill.

This study investigated three pre-service teachers' mathematical problem solving among hand-in-write-ups and final projects for each subject. All participants' activities and computer explorations were observed and video taped. If it was possible, an open-ended individual interview was performed before, during, and after each exploration. The method of data collection was observation, interviewing, field notes, students' written assignments, computer works, and audio and videotapes of pre- service teachers' mathematical problem solving activities. At the beginning of the mathematical problem solving activities, all participants did not have strong procedural and conceptual knowledge of the graph, making a model by using data, and general concept of a sine function, but they built strong procedural and conceptual knowledge and connected them appropriately through mathematical problem solving activities by using the computer technology.

The construction industry is still the most risky industry and labor accident is a significant management factor on construction site. Safety management has been studied for improving the safety performance on construction sites. However, Almost all of them have been considered on the site safety management for the contractors and evaluation of accident rate. To resolve the limitation of current research, this study is focused on considering accident result and effort by performing the evaluation of safety level of the head office and site in construction companies. By studying the research about a safety management and interviewing with specialists in safety management, 7 items were selected and weighted based on the KOSHA18001 List. Consequently, The checklist was developed to evaluate safety performance management in construction company and Safety Management Index was suggested to coordinate 1) the score of results in accident rate and 2) the effort to evaluate a safety performance management. Safety Management Index is more helpful to evaluate the safety management results and effort. As a result of considering the score of the accident rate and the safety performance management, the outcome of prequalification was changed. Using this index, contractors will attempt to prevent accidents and owners will be able to discriminate individual differences in bidding process.

PISA의 연구 결과에 따르면 컴퓨터 활용 빈도나 ICT 활용 환경 등의 양적 활용 실태는 세계적인 수준이나 프로그램이나 소프트웨어 활동 등의 컴퓨터 질적 활용 정도는 제고될 필요성이 있는 것으로 나타났다. 이는 초등 컴퓨터 교육에도 시사하는 바가 크다. 하지만 인적 물적 여건 등으로 인해 프로그래밍 교육을 초등학교 현장에 바로 적용하기에는 무리가 있다. 따라서 본 논문에서는 언어의 복잡성이 낮고 프로그래밍 단계와 과정이 간단한 HTML을 현장에 효과적으로 적용하기 위한 텍스트 에디터를 개발하고 개선점을 찾아보았다. 텍스트 에디터는 우선 태그를 직접 칠 필요가 없으며 학생들이 쉽게 학습할 수 있도록 도움말을 제시해 주었고 간단한 이미지 뷰어 기능을 통해 쉽게 이미지를 넣을 수 있도록 하였다. 개발된 텍스트 에디터의 효과를 설문지로 조사한 결과 쉽게 HTML 문서를 작성할 수 있어 학습에 도움이 된다는 점과 도움말을 제시한 부분은 긍정적으로 평가된 반면 보다 UI를 좀더 개선해야 한다는 결과가 나왔다.

The purpose of this investigation was to help university professors for making their systematic design of instruction easily and scientifically. To increase of learner's studying ability, the systemic instructional design is imperative. But most of university professors could not get proper experiences to know develop instructional design system, specially to develop web-based system. This new system made it possible to select the proper instructional methods and the media type suitable for the corresponding data. And also every professor who is involved to know this system, can put informations for the target learners, learning contents and learning objectives, and present the proper media types and the many different conditions in the process of the each instructional design process. Finally, the results of the learner's study will be effective and professors showed their positive opinions for the using of the system.
