Reading education has been recognized as being important area in the education. But it has many limitations to achieve education effects, because it is very difficult to process in reality. In these days, traditional education methodology needs to be changed for the development of computer science and network communications. It is also applied at the area of reading education. To achieve educational goal in reading education, students must be able to interchange their views without restrictions of time and space. Through this circumstances, they can improve logical thinking and discussion ability. Therefore we need the reading education system which supports reading actions as well as reading instruction. In this paper, a web based reading education system is designed and implemented to improve logical thinking and discussion ability.

Regardless of the strict enforcement of prevention education in accordance with the school facility management standard, safety accidents that lead to human and physical damages occur in current educational facilities because of teenagers with very low sense of responsibility and insensitivity toward fire and facility safety. To ensure educational facility safety, technology that will enable a fast work process and easy confirmation of electronic blueprints and related documents about the educational facility through smart devices at the site by various means is needed. This paper proposes a system design linked to the National Education Information System (NEIS) that uses the document conversion function, high efficiency resolution, and Internet of Things (IoT) to inspect and control the educational facility in the event of a safety accident through the Educational Facility Resource Management System (EFRMS) that manages the electronic blueprints, and various educational facility documents through various smart devices.

The purpose of this study was to identify the effect of simulation integrated with problem based learning(SIM-PBL) on nursing students. A non-equivalent pre-post test of quasi-experimental design was used. 37 were assigned to an intervention group and 41 to a control group. SIM-PBL was applied to intervention group and simulation was applied to control group. Data were analyzed using the SPSS 20.0 program. There were significant increases in system thinking(t=2.14, p=.036), proactivity in problem solving(t=2.07, p=.042), and performance ability for medication(t=5.26, p=<.001) in the intervention group compared to the control group. However, there was no difference in learning flow between the intervention and control groups. In order to adapt to the clinical setting, it is necessary to consider the SIM-PBL needs to be considered in the curriculum of nursing students.

One of the problems with current youth generations is increasing rate of violence and suicide in their school lives, and this study aims at the design of a sentiment analysis system to prevent suicide by uising big data process. The main issues of the design are economical implementation, easy and fast processing for the users, so, the open source Hadoop system with MapReduce algorithm is used on the HDFS(Hadoop Distributed File System) for the experimentation. This study uses word count method to do the sentiment analysis with informal data on some sns communications concerning a kinds of violent words, in terms of text mining to avoid some expensive and complex statistical analysis methods.

In this study, we proposed the learning activities using open community systems to increase critical thinking and cooperative work. We designed and implemented the Wiki system that is an opened community and general Web-Board system that is a closed community. Then, elementary students had the critical essays activities using these systems. The results of the study are as follows. First, the critical thinking activities were happened more actively at the Wiki system than at the Web-Board system. And we found that the critical thinking dispositions were improved at the Wiki system after students performed the critical writing activities. The critical thinking activities also occurred more actively in cooperative groups than in studying individual groups. In conclusion, when the students learn with the open community like the Wiki system than closed community, it is hoped that they would participate actively and their critical thinking would be improved better.

The more a society becomes complicated and diversified along with the economic development, the more diverse l earning types the educational activities had beyond the existing educational approaches to cope with the complicated and diversified society. In particular, field studies and opportunity to use the dangerous educational appliances have been increasing in order to cope with the desires of education consumers requiring diversity and the individuality of students has been strengthened. In accordance with the trends above, the school accidents have been gradually increasing in recent days. Thus, this paper aims to propose the suggestions to teachers in real education fields by investigating the problems in compensation system of School Safety and Insurance Association against which the victim s of any school safety accidents firstly claim for the damages, the problems in the present system of the Association and how to improve the system in terms of the payment scope of the Association.

In spite of advanced navigational devices and reinforced mandatory standards of officers' education, the number of ship's accidents are increasing. The accidents caused by minor license officers are more than the number of accidents caused by superior license officers. There are many cases of collisions in the past 5 years released on Marine Accidents Inquiry Agency. Especially, officer's negligence from the consequences of the neglect of any precaution which may be required by the ordinary practice of seamen is the main reason behind ship's collisions. For reducing ship's accidents caused by human error, this paper suggests to develop effective training program using analysis date of domestic and foreign education system as a reference.

본 논문에서는 울진 표준형원전 시뮬레이터의 강의실용 교육훈련 시스템의 일원으로 개발된 CBT (Computer Based Training) 및 WBT (Web Based Training)에 대해 다루고 있다. CBT는 발전소 시뮬레이션, 노심 다이나믹스, 중대사고, 비상발령 및 증기발생기 열변환 과정으로 구성되어 있다. Simulator Operation 기능을 이용하면 강사는 강사조작 메뉴를 통하여 시뮬레이터를 조작을 할 수 있고, Sim-Diagram 등 각종 화면을 보여줄 수 있다. 중대사고는 모의사고에 의해 구축된 데이터를 근거로 하여 개발되었으며, 방사선 비상등급에 따라 백색비상, 청색비상, 적색비상으로 구성된 비상발령은 각 발령의 발령상황 등을 Open Window를 통하여 볼 수 있도록 하였다. 한편 WBT는 강사와 교육생이 강의실 이외의 장소에서 시간과 공간의 제약을 벗어나서 원격교육이 가능하도록 구축한 웹서버 환경이다. 현재는 기존에 구축된 강사들의 홈페이지를 Intra-Net환경에서 접근이 가능하도록 링크된 상태에 있다. 향후에는 일부내용에 대해서는 원격으로 강의가 가능하도록 다양한 컨텐츠를 개발할 예정이며, 현재는 발전소 운전과 관련한 교육자료, 각종 동영상 및 이미지, 각종교재 등에 대한 DB 구축을 준비중에 있다

The purposes of this study were to analyze high school students' understanding about the Earth system and systems thinking process, and to develop science writing programs designed to assess students' understanding about themes of Earth Science such as global warming, volcanoes, and desertification. A total of 8 $11^{th}$ grade students from general high schools participated in the writing program and draw the causal maps. The methods of this study are as follows. First, DAET-C was used to investigate the way of students' understanding about the Earth systems. What the students' best understood was the component of the Earth systems followed by the interaction of the Earth systems and the scientific literacy of Earth science. Second, feedback circulations on the causal maps were found in four students in global warming section, one student in volcanic eruption section, and four students in desertification section, which means that systems thinking was not largely employed by the students. Consequently, the student participants understood that the global change was happening in correlation with complex concepts and factors, but they were short of using systems thinking in their science study. Therefore, the result of this study suggests that more studies be conducted to develop systems thinking in Earth Science learning through science writing programs.
