  • Sea Surface Temperature (SST) is one of the most important oceanic variables to understand rapidly-changing climate, so that accurate and error-free SST images should be presented in school science textbooks. However, satelliteobserved SST images in the high-school textbooks presented some errors caused by various reasons. This study analyzed 36 satellite images for SST presented in 24 kinds of high-school textbooks (earth science I and II textbooks on the basis of the 7th National Curriculum) for 17 items. This study investigated errors in image processing such as cloud removal, land masking, color bar, geological and time information, and some erroneous expressions related to the fundamental information of satellites. Twenty five pre-service teachers filled out a survey about several problematic satellite images, and their responses were analyzed. As a result, most of the pre-service teachers did not recognize the errors associated with image processing and tended to comprehend the SST errors as real oceanographic phenomena such as sea ice, river outflow, or cold current. Therefore, satellite SST images in the textbooks should be accurately presented by including detailed items suggested in this study.

  • The purposes of this study are: (1) to develop educational program designed to improve high school students' knowledge integration and their system thinking skills about global warming and (2) to identify the change of students' system thinking level. The developed program was implemented to twenty seven high school students, and six students grouped into three highs and three lows in their performance were selected to analyze their level of system thinking. The word association, casual map and drawing were used to measure and identify any significant change. As a result, the low level system thinking group improved their system thinking skills for global warming and the earth and sub-systems after the intervention. However, participants' misconception remained the same. And the high level systems thinking group showed more organize system thinking skills about a global warming topic. It is suggested that more educational programs be developed on various topics in order for high school students to improve their systems thinking skills as well as knowledge integration of earth systems and earth environment in school curriculum.

  • An Emergency Medical Technician (EMT) is a well-trained emergency responder to provide emergency medical services to the critically ill and injured patient. In various situations, EMT may destroy potential physical evidences associated with the crime scene or determination of real cause of death. This study was aimed to evaluate the educational need of forensic medicine in Korean EMT. Questionnaires were administered to 592 EMTs during March 2007. The response rate was 60.3%(357 EMTs). In questionnaires there were 13 questions regarding the general characteristics, 16 questions about roles of EMTs related with forensic circumstances, 9 questions about the education related to forensic medicine. Questionnaires rated on a 4-point Likert scale or 5-point Likert scale. Most of 119 rescue EMTs had experienced with situations related to crime or unexpected sudden death. EMTs had arrived to the scenes earlier than police and complained of some difficulties related with deficit of forensic knowledge. EMTs wanted to receive continuous educations about forensic medicine. In order to reduce dissatisfaction with EMTs roles and to improve crime scene preservations, Emergency Medical Services policies should provide regular educational curriculum by forensic pathologists and promote legal responsibilities for 119 rescue EMTs.

  • An emerging learning method, flipped learning, has gained much interest lately due to its process involving prior study followed by the students' classroom involvement, which direction matches that of the current educational policy that emphasizes self-directed learning. This study investigated the concept of flipped learning and explored ways to develop instructional design models that utilize it. Flipped learning is not a model that has been recently developed, as it uses the format of blended learning with the introduction of a new concept of prior learning that allows students to learn in advance through online lessons and video clips related with the classroom content to be covered. During class time, individualized supplementary or in-depth study is conducted on the basis of the students' prior learning. The main considerations for designing flipped learning are a flexible classroom environment, a shift in learning culture, intentional classroom content, and educators equipped with professional capability. The research proposes the development of instructional design models for flipped learning pursuant to such concept and considerations. Through this research, the concept of flipped learning can be comprehended; furthermore, flipped learning can be utilized more effectively in the teaching and learning environment.

  • The purpose of this study was to examine difference in quality of chest compression according to encouragement method of focusing on two rescuers' teamwork in CPR guideline for 2010. Subjects were randomly extracted the Dept. Emergency Medical Technology students who completed the curriculum of CPR. A group was divided into the group with one-time encouragement(33 people) and the group with continuous encouragement(33 people). Measurement period was progressed from April 30, 2012 to May 7. The collected data were analyzed with SPSS WIN program(version 12.0). As a result of research, the accuracy of chest compression(time, %) was higher(p<.05) in the group with one-time encouragement(118.72 times, 78.54%) than the group with continuous encouragement(95.12 times, 62.96%). As for the recognition of subjective concentration, the recognition as saying of being helpful for concentration was higher(p<.05) in the group with one-time encouragement(3.90 points) than the group with continuous encouragement(3.12 points). Even as for the recognition of subjective fatigue relief, the recognition as saying of being helpful for fatigue relief was higher(p<.05) in the group with one-time encouragement(3.96 points) than the group with continuous encouragement(3.30 points).

  • This study aims to investigate the improvement in basic CPR quality on the basis of the hip joint angle of the rescuer among students in the Department of Emergency Medical Technology who completed a basic CPR curriculum. In this study, we carried out a comparative analysis using SimPad SkillReporter and Resusci Anne® QCPR® to measure the quality of CPR (depth of chest compressions, full relaxation, compression speed, and more) on the basis of the rescuer's hip joint angle in accordance with the 2015 AHA Guidelines and conducted chest compressions and CPR 5 times in a 30:2 ratio. It was found that maintenance of the rescuer's hip joint angle at 90 degrees while compressing and relaxing the chest made a statistically significant difference in both the experimental and control groups. Moreover, this indicated that the closer the hip joint angle was to 90 degrees, the better was the quality of basic CPR. However, there was no significant difference in the hip joint angle, degree of CPR, depth of chest compressions, chest compression speed, chest compression and relaxation percentages (%), accuracy of chest compressions, hands-off time during CPR, and percentage of chest compression time (p > 0.05). Maintaining the hip joint angle at 90 degrees for basic CPR was not significantly different from not maintaining this angle. Nonetheless, good results have been obtained at moderate depth and 100% recoil. Therefore, good outcome and high-quality CPR are expected.

  • This study is a descriptive research study to grasp the critical thinking tendency, clinical practice stress, core basic nursing confidence, and degree of adaptation to clinical practice in nursing students. From June to July 2019, 207 students in the fourth year of nursing college were surveyed through their own questionnaire. Collected data were analyzed by t-test, ANOVA and multiple regression analysis using SPSS/WIN v24.0. The negative correlation between clinical practice stress and critical thinking tendency(r=-.18, p=.010). The core self-confidence practice self-confidence showed a positive correlation with critical thinking tendency(r=.25, p<.001), and a negative correlation with clinical practice stress(r=-.17, p=.017). Adaptation to clinical practice showed a positive correlation with clinical practice stress(r=.44, p<.001), and the factor influencing clinical practice adaptation was stress(β=.40) (F=18.34, p<.001), and the explanatory power was about 23.1%. As mentioned above, stress brings a positive change to clinical practice, so it is necessary to identify stress factors received from clinical practice of nursing college students and reflect them in curriculum development.

  • This study surveyed 60 early childhood teachers at the kindergartens and day care centers in Incheon Metropolitan City to examine the contents and extent of the teachers' knowledge on early childhood history education by using the definition map designed by Novak and Gowin(1984). To be more specific, the researcher asked the participating teachers through group meetings to draw the definition maps and analyzed them. The results were as follow. First, 11 categories for high level definition of early childhood history education used by early childhood education were identified, among which the most frequently used high level definition were 'life style' followed in order by 'culture/art' and 'great men.' Second, in terms of the average number of dependent definitions included in the given high level definitions, the largest was 'life style' which was followed in order by culture/art, activity methods. It means that the widest area of early childhood teachers' knowledge on early childhood history education was about 'life style,' while it shows that the extent of knowledge on teaching-learning methods was relatively wide. However, in the case of great men, although it was frequently recognized in the high level of definition it was not so in the dependent definitions, meaning the extent of their knowledge was rather narrow. Scholars explain that the higher the teachers' attention and knowledge about the content of curriculum the more options of teaching method they tend to employ to teach in a more extensive and diverged way. Therefore, in order to improve early childhood education, efforts should be more focused on deepening and systemizing the knowledge of early childhood teachers.
