The ethical issue is one of the most important themes in both science and environmental education. Especially related to the right of other species, animal dissection has been brought about two contradictory attitudes. In spring 1996, a survey was conducted to assess the status of animal dissection in secondary schools and the awareness of 94 biology teachers and 422 secondary students toward animal dissection. And the meaning of animal dissection in biology class was discussed in terms of environmental education. The findings were as follows: First, most of students(96.6%) had participated once or twice to animal dissection experiments(eg. fish, frog, shellfish, cuttlefish and chicken). And about half of teachers (57.4$\sim$64.9%) and some students(41.9%) felt ethical conflict in animal dissection. Second, many teachers(81.0%) and students(87.1%) thought that animal dissection was effective method to achieve the goal of biology education, but they needed more consideration on the respect for life in animal dissection experiment. Third, many teachers(88.3%) had students, who objected to animal dissection, participate obligatorily or passively. Fourth, teachers and students thought that audio-visual media such as video(teachers 63.5%, students 39.7%), computer simulations(teachers 31.7%, students 28.1%) and models(teachers 22.2%, students 24.1%) could be effective as alternatives. These findings suggest that animal dissection experiment, although it is needed to achieve the goal of biology education, requires careful consideration on the rights of animal and the respect for life, and alternatives for students who object to animal dissection in biology class.

The purpose of this study was to examine the students' responses and self-understanding in the liberal arts and personality class, one of the compulsory liberal arts subjects at S University. The results of the study are as follows. First, the degree of influence on students' positive change in this class was higher than normal using a five-step Likert scale. In particular, as a result of the film discussion conducted by the researcher, satisfaction was very high. Second, as a result of picture test analysis, changes in coping ability through stress and resource scales were seen in the students, and it was an opportunity for students to understand themselves by looking into their minds. This study presented example of classes that can cultivate students' personality through literature, art, and video, and cultivate their qualities as global citizens, such as responsibility, leadership, cooperation, consideration, communication, and empathy, through discussion.
The objective of this study was to conduct a 'Theory of Home Economics Education' class using online problem-based learning(PBL) for prospective home economics(HE) teachers. The aim was to enable teachers to analyze the learning experience in the classroom, and to prepare operational strategies for online PBL on this basis. In order to achieve this, online PBL was applied to 31 students participating in the 'Theory of Home Economics Education' at the Department of HE in a university in Seoul, and the results were collected from the learning process. This also involved a reflective journal, a survey on the learning experience and the impacts was conducted. Moreover, analysis was undertaken on the learning activities, learning difficulties, and improvements. The main research results are as follows. Firstly, students accessed Webex, an online video conferencing program, and performed two PBL tasks: 'Making Home Economics Promotion Materials' and 'Presenting Teaching Strategies to Improve Learner's Immersion in Online Classes'. Secondly, learners established their own identity of HE learned about the HE class plans themselves. They also encountered realistic experience as HE teachers and learned communication and collaboration skills. Furthermore, they acquired creative problem-solving and self-directed learning ability, community consciousness, as well as the attitude of consideration and respect. Thirdly, students lacked knowledge of learning content and encountered difficulty in solving data research, analysis processes, and unstructured problems. They were affected by a lack of time and encountered problem in communicating with other team members in an online environment. As an improvement in online class operation, it was considrered necessary to reduce the learning burden by securing time and reducing the number of assignments, as well as to explain active interaction with instructors and PBL.
This study compares two cases in which flipped learning is applied in the active learning classroom (ALC) and fixed classroom of advanced engineering education. To this end, the difference in pre-learning, academic achievement, and class satisfaction between ALC and fixed classroom flipped learning were compared. The results revealed that students in ALC flipped learning watched more video lectures for pre-learning than those in the fixed classroom flipped learning and achieved higher scores on final tests, though they obtained lower points on midterm exam. In addition, examination of class satisfaction with questions about class factors, instructor factors, and overall satisfaction revealed that ALC flipped learning showed higher satisfaction in all factors than the fixed classroom flipped learning. This case study suggests that the ALC environment, a learning space built to facilitate learner-centered activities, is more effective for flipped learning that requires active interaction in the classroom.
The present study explores how the quality management rhetoric commonly used by Korean CEOs tends to be composed and perceived by the public. To this end, articles of the remarks of Lee Kun-hee, the second founder of Samsung, are analyzed. The results show a rhetorical structure of quality management where the CEO offers a persuasive theme (quality management for a super-class enterprise) and practical measures (innovation and performance-based promotion) while coping with a rhetorical situation (an economic crisis). A multiple regression analysis of the response of 308 Korean college students who watched a video of Lee's remarks indicates that the more conservative the viewers are and the more they perceive the CEO's charm and expertise, the more likely they are to support the CEO's quality management rhetoric. The conservative viewers favorably responded to the entrepreneurship in the quality management rhetoric, while the progressives recognized the rhetoric as part of Korean-style neoliberalism that alienates ordinary workers.

The purpose of this study is to examine the effects of science classes using the geological materials of a locality on academic achievement and scientific attitude of elementary school students. For this study, the class unit is 'stratum and fossils', 2nd semester of 3rd grade, and the geological materials of a locality is applied for class. The geological materials used in teaching and learning of 'stratum and fossil' unit are photographs & video data relating to geological phenomenon, and rock & fossils samples collected in Jeollanam-do province. This study has been aimed at 2 classes 47 students of 3rd grade in G elementary school of G metropolitan. One class 23 students are the research group to apply science class using the geological materials in a locality, on the order hand another class 24 students are the comparison group to apply general science classes. The results of this study are follows. First, a positive relationship was identified between academic achievement and science class applying the geological materials in a locality in the research group. This shows that academic achievement was improved by science class applying the geological materials in a locality. Second, a positive relationship was identified between scientific attitude and science class applying the geological materials in a locality in the research group. This shows that scientific attitude was improved by science class applying the geological materials in a locality. Third, by the results of interview with students who was participated in science class applying the geological materials in a locality, it shows that they have interest and curiosity about local geology. Above results means that science class applying the geological materials in a locality help elementary schools students improve the educational effect about 'stratum and fossils' unit. Thus, it is needed to use the geological materials of a locality in science class relating to the geology units of elementary school science in order to improve academic achievement and scientific attitude of elementary school students.
Purposes : This study reports the possible causes of seizure recurrence in patients underwent previous epilepsy surgery, and surgical strategy for resection of the additional epileptogenic zone locating at the distant area to the site of first resection. Methods : A total of 10 patients with previous surgery due to intractable epilepsy were studied. Five of these underwent standard temporal lobectomy, four extratemporal resection, and one corticoamygdalectomy. Seizure outcome of these were class III-IV. Evaluation methods for reoperation included MRI, 3D-surface rendering of MRI, PET, prologned video-EEG recording with surface electrodes and subdural grid electrodes. Additional resection was done in the frontal lobe in two, in the temporal lobe in three, in the parietal lobe in two, and in the supplementary sensori-motor area in two. Tumor in the superior frontal gyrus in the left hemisphere was removed in one patient. Extent of resection was decided based on the results of ictal subdural grid EEGs and MRI findings. Awake anesthesia and electrocortical stimulation were performed in the two patients for defining the eloquent area. Results : Histopathologic findings revealed extratemporal cortical dysplasia in six, hippocampal sclerosis and cortical dysplasia of the temporal neocortex in one, neuronal gliosis in two, and meningioma in one. Previous pathology of the five patients with cortical dysplasia in the second operation was hippocampal sclerosis plus cortical dysplasia of the temporal neocortex. After reoperation, seizure outcomes were class I in six, class II in three, class III in one at the mean follow-up period of 17.5 months. Characteristically, patients in class II-III after reoperation showed histopathologic findings of hippocampal sclerosis plus temporal neocortical cortical dysplasia plus extratemporal cortical dysplasia. Conclusions : Seizure recurrence after epilepsy surgery was related with the presence of an additional epileptogenic zone distant to the site of first operation, and the majority of the histopathology of the surgical specimens was cortical dysplasia. In particular, hippocampal sclerosis plus temporal neocortical cortical dysplasia was highly related with seizure recurrence in patients with previous operation. In these patients, multimodal evaluation methods were necessary in defining the additional epileptogenic zone.
The advances in science technology brought about a new form of learning called flipped-learning: a combination of on-line and off-line learning. A flipped learning is a form of blended learning which has become quite popular, nowadays, in the field of education. Despite the emphasis on the importance of medical humanities in medical education program, there are no effective teaching and learning models to realize the purpose of medical humanities education. This study explores the possibility of flipped-learning to apply medical humanities classes. The class was designed based on the ADDIE model consisting of five stages, analysis - design - development - execution - evaluation. In order to do 'flipped-learning,' the instructor reconstructs the purpose of medical humanities education, instructional purpose and content, and analyzed learner. The contents of the medical humanities class were structured considering the purpose of the introduction to the medical humanities in the medical education program and the competencies that medical personnel should have in the developed health care environment. The instructor produces a video of the lecture and makes it possible to use LMS (Learning Management System) before and after classes, and conducts discussion activities so that learner-learner and learner-teacher interaction could actively occur during the class. The result of applying medical humanities lesson as flipped learning is as follows: First, it can realize the essence of medical humanities education. Second, it contributes to strengthening the competencies of health care provider. Third, flip learning can be used as a new teaching strategy for medical humanities education. The result of this study is expected to suggest new ways of introduction to teaching method in the traditional medical humanities class and contribute to the practice of designing and doing flipped learning of medical humanities class in the future.

The study presented an online class case focusing on G University's writing course, and analyzed students' satisfaction. Through this, it aimed to analyze the possibility of online education and to explore efficient operation of online writing lectures. According to the result of looking into the online writing class run by G University, students' satisfaction with the online writing class was high. Despite the limited circumstances, students' participation in the class was high and they also actively participated in online correction. However, there was also a challenge to address. Online writing education showed limitations in terms of smooth communication with students. Correction of writing can be done online sufficiently but the limitations of communication should be supplemented to improve the completeness of interactive education. In addition, most of the students participated in online correction, but some did not participate. It is necessary to encourage students to participate voluntarily to make online classes take roots. After all, for the effective operation of online writing classes, strategies and systems for teaching and learning should be prepared for utilization of various educational video media, sufficient learning of theory and practice of writing, and smooth communication between professors and students. Only when these conditions are met, online writing classes will be able to operate steadily.

We present a novel method for eye location by means of a two-level classifier scheme. Locating the eye by machine-inspection of an image or video is an important problem for Computer Vision and is of particular value to applications in biomedical imaging. Our method aims to overcome the significant challenge of an eye-location that is able to maintain high accuracy by disregarding highly variable changes in the environment. A first level of computational analysis processes this image context. This is followed by object detection by means of a two-class discrimination classifier(second algorithmic level).We have tested our eye location system using FERET and BioID database. We compare the performance of two-level classifier with that of non-level classifier, and found it's better performance.
