A 6-year-old female domestic short hair cat presented with acute onset of vomiting, anorexia, lethargy, and tachypnea. The cat was apparently healthy prior to presentation without history of trauma. On diagnostic imagings, the entire stomach and spleen were detected in the thoracic cavity. An emergent celiotomy was performed, and a type-4 hiatal hernia was confirmed; the stomach, spleen, pancreas, and duodenum were herniated through the esophageal hiatus. It was corrected using phrenicoplasty, esophagopexy, and left-sided gastropexy and there was no recurrence 16 months after surgery. This is the first case report of an idiopathic type-4 hiatal hernia in a cat.

The purpose of this study is to analyze that hours for participating in CTL program and whether or not make of CQI have a effect on the student evaluation about teaching of engineering professor. This inquiry have done a multiple regression analysis that student evaluation grade of teaching on 2018-1st semester of 240 engineering subjects of N University in Chungcheongnam-do as dependent variable, and background factors and work factors as independent variable. Research results is follows. First, employment type haven't a effect on teaching evaluation scores. And subject type, student' concentration of class, teaching evaluation pre-scores have a positive effect on teaching evaluation rating, but student number have a negative effect. Second, hours for participating in CTL program haven't a effect on teaching evaluation scores, but to make of CQI report have a positive effect on teaching evaluation scores. And I suggested to make CQI for improve teaching evaluation scores and manage the quality of education.

본 연구는 이중부호화, 매체풍부성, 인지부하의 정도가 다른 e-러닝 콘텐츠가 학습에 미치는 영향을 살펴보고자 실행되었다. 이를 위해 e-러닝 콘텐츠의 학습내용 요약과 설명의 정보제시방식을 정보 양과 종류에 띠라 분류한 후, 교수실재감과 학업성취도에 미치는 영향을 살펴보았다. 요약 제시방식은 텍스트형과 텍스트+그림형으로, 설명 제시방식은 음성형과 음성+영상형으로 구분하였다. 본 연구의 결과는 다음과 같다. 첫째, 요약방식 중 텍스트+그림형의 교수실재감이 텍스트형보다 의의 있게 높았다. 둘째, 설명방식 중 음성형의 학업성취도가 음성+영상형보다 의의 있게 높았다. 셋째, 요약방식과 설명방식 간에 교수실재감과 학업성취도에서 유의미한 상호작용이 있었다.

The purpose of this paper is to apply the newly developed SICAT teaching and learning model to the actual scene of teaching and learning and draw a point of discussion for utilizing teaching and learning model, by uncovering the satisfaction of students and the inhibiting/facilitating elements when using the model. SICAT(Scientific Inquiry and Creative Activity with Technology; from here on SICAT), a teaching and learning model custom-built for engineering education, was developed, as more and more people paid attention to the demand for creative engineers. It was developed from the basis of PBL(Problem Based Learning), includes three sub-types which can be applied to the actual theory, design, and experimentation fields within engineering education. The three sub-types, which are ARDA(Analysis-Reasoning Activity & Discussion-Argumentation Activity), CoCD (Collaboration Activity & Capstone Design Activity), and ReSh(Reflection Activity & Sharing Activity), respectively support deductive and argumentation activities, creative design and collaboration activities, and retrospection and sharing activities. However, no research has been conducted to investigate whether or not there are inhibiting or facilitating elements in the application procedure, or what the rate of satisfaction for students is, when applying the SICAT model, which was newly developed to innovate existing engineering education, to the actual site of teaching and learning. Therefore, this research applied three types of SICAT teaching and learning models to the theory, design, and experimentation classes at the department of materials science and engineering at Hanyang University for eight weeks. After application, the students, teachers and tutors were surveyed and interviewed, and then the results analyzed in order to uncover inhibiting/facilitating elements and the rate of satisfaction. The satisfaction rate of students from the SICAT teaching and learning model was 3.78(in a perfect score of 5: The A type-3.65, The C type-3.80, The R type-3.90), and inhibiting/facilitating elements were drawn from the aspects of learning activities, support system. In conclusion, they can be contributed for implications of SICAT teaching and learning model universal use at engineering education in University.

There is increasing attention about radiology teaching files on the Internet in the field of diagnostic radiology. The purpose of this study was to aid in the creation of new radiology teaching file by analysing the present radiology teaching file sites on the Internet with many aspects and evaluating images on those sites, using Macintosh IIci computer, 28.8kbps TelePort Fax/Modem, Netscape Navigator 2.0 software The results were as follow : 1. Analysis of radiology teaching file sites (l) Country distribution was the highest in USA(57.5％). (2) Average number of cases was 186 cases and radiology teaching file sites with search engine were 9 sites (22.5％). (3) At the method of case arrangement, anatomic area type and diagnosis type were found at the 10 sites(25％) each, question & answer type was found at the 9 sites(22.5％). (4) Radiology teaching file sites with oro-maxillofacial disorder were 9 sites(22.5％). (5) At the image format, GIF format was found at the 14 sites(35％). and ]pEG format found at the 14 sites(35％). (6) Created year was the highest in 1995(43.7％). (7) Continuing case upload was found at the 35 sites(87.5％). 2. Evaluation of images on the radiology teaching files (l) Average file size of GIF format (71 Kbyte) was greater than that of JPEG format(24 Kbyte). (p<0.001) (2) Image quality of GIF format was better than that of JPEG format. (p<0.001).

The aim of this study was to perform a meta-analysis of the learning outcomes of immersive learning technologies in English language teaching (ELT). This study examined 12 articles, yielding a total of 20 effect sizes. The Comprehensive Meta-Analysis (CMA) program was employed for data analysis. The findings revealed that the overall effect size was 0.84, implying a large effect size. Additionally, the mean effect sizes of the dependent variables revealed a large effect size for both the cognitive and affective domains. Furthermore, the study analyzed the impact of moderator variables such as sample scale, technology type, tool type, work type, program type, duration (sessions), the degree of immersion, instructional technique, and augmented reality (AR) type. Among the moderators, the degree of immersion was found to be statistically significant. In conclusion, the study results suggested that immersive learning technologies had a positive impact on learning in ELT.

In this study, we investigated the variables related to the science teaching efficacy beliefs of pre-service and in-service elementary school teachers. The participants were 176 freshmen and 260 seniors from an university of education and 234 teachers from 25 elementary schools located in Jeonju. Variables concerning pre-service teachers include their sex, career/study tracks (science or non-science), and the number of science courses taken either at high school or at university. Variables concerning in-service teachers include their sex, academic degree, the frequency and type of participation in science in-service training, and their teaching career experience. The Science Teaching Efficacy Beliefs Instrument was used to measure teachers' self-efficacy beliefs. The results indicated that the personal science teaching efficacy belief scores of seniors were significantly lower than those of freshmen and in-service teachers, whereas the science teaching outcome expectancy scores of seniors were significantly higher than those of freshmen. Among variables investigated, sex, career/study track, the number of science courses taken at high school, and the frequency and type of participation in science in-service training were found to significantly influence teachers' science teaching efficacy beliefs.

이 연구는 강완, 김남준(2010) 이 Wittmann(1984)의 이론을 근거로 2007년 개정수학과 교육과정에 근거한 교수단위를 추출한 것과 동일한 방법을 통해 도형영역의 교수단위를 분석한 것이다. 교수단위는 수학에서 가르쳐야 할 내용들을 목적, 자료, 활동, 배경 등의 4 요소에 따라 알갱이 단위로 조직화 한 것이다. 본 연구에서는 2007년 개정수학과 교육과정 도형영역에서 추출된 교수단위의 특징과 제목을 분석하여 교수단위를 개념알기형, 개념적용형, 관계알기형으로 분류하여 교육적 의미를 살펴보았다. 또한, 도형영역의 교육과정연구에 어떻게 활용될 수 있는지 그 방안을 모색해 보았다. 앞으로 많은 수학연구자와 현장 교사의 참여로 교수단위가 보다 체계적으로 조직적으로 연구된다면 새로운 교육과정을 수립하는 데 중요한 자료로 활용될 수 있다.
