Recently, an advanced form of blended learning, which incorporates a teaching method that focuses on flipped learning is actively used in colleges. Flipped learning is for learners to pre-learn content through videos uploaded by instructors before class, and then participate in learner-centered learning activities such as discussions and team activities in the classroom. The purpose of this paper is to review where flipped learning is being used in medical schools, and to draw implications for effective and efficient use in medical schools. For this, the definition of flipped learning, how it evolved, educational usefulness of this method of learning, and application cases in medical schools were reviewed. Through the reviews of cases of flipped learning and its positive effects, it is suggested that medical schools consider more use of flipped learning in the classroom instructions, with sensitivity to the individual medical departments' needs, environment and professors' preferences.

Brain tumor surgery may be difficult, but it is also incredibly important. The technological improvements for traditional brain tumor surgeries have always been a focus to improve the precision of surgery and release the potential of the technology in this important area of the body. The need for precision during brain tumor surgery has led to an increase in Robotic-assisted surgeries (RAS). One of the challenges to the widespread acceptance of RAS in the neurosurgery is to recognize invisible tumor accurately. Therefore, it is important to detect brain tumor size and location because surgeon tries to remove as much tumor as possible. In this paper, we proposed brain tumor detection procedures for MRI (Magnetic Resonance Imaging) system. A method of automatic brain tumor detection is needed to accurately target the location of the lesion during brain tumor surgery and to report the location and size of the lesion. In the qualitative assessment, the proposed method showed better results than those obtained with other brain tumor detection methods. Comparisons among all assessment criteria indicated that the proposed method was significantly superior to the threshold method with respect to all assessment criteria. The proposed method was effective for detecting brain tumor.

Objective : The college of Korean medicine uses a variety of Korean medical classics. Thus, in order to overcome the natural difference of the details of their curriculum, this paper aims to study the usage of Flipped Learning as a way of standardizing the curriculum that teach Korean medical classics. Method : One effective teaching and learning methodology, which is called for by the changing educational paradigm, is Flipped Learning. To introduce this learning method, which is actively applied to different curriculum, the paper revises the goal of learning objectives and introduces a teaching model of Flipped Learning in order to suggest the standardization of Korean medical educations through the re-design of the curriculum for Korean medical classics. Result : The professors of the Korean medical classics must work together to use the revised learning objectives and teaching model and create a set of lectures to serve as a basis of educational standardization. Conclusion : The standardization of the education of Korean medical classics through the Flipped Learning method could pre-emptively deal with the Korean medical doctor's capacity model that is in development now.

Pharmacopunture is a new combined method of acupunture and oriental drugs. Recently, this method is widely used to treat traffic accident patients in oriental medicine. However, there is no evidences of treatment, no information of effects and side-effects of this method, and no information of drugs used. In South Korea, western medicine and oriental medicine are regulated differently. When a new technology is invented in the area of western medicine, that method should pass several stages of clinical trials. After that processes, that method can be done as a medical practice. However, in the area of oriental medicine, there is no process like that. According to in South Korea, medical practice without license are composed of two behaviors. First type is that medical practice is done by a person who has no medical license. Second type is that medical practice is done by a person who has a medical license but the area of the license is different. Because of this reason, the distinction between the western medical practices and the oriental medical practices is very important. Medical practices are protected by license mainly because they can harm human life or body. When we invented new medical practice and try to practice it to the patients, we should consider the risk of that method whether it is western medical practice or oriental medical practice. It is not clear that the pharmcopunture which has been done is satisfied the standard of medical treatment.

We have known that "Chimgudaeseong(鍼灸大成)" had been written by Yanggyeju(楊繼洲) in Myeong(明) Dynasty. And it had been the only text book of acupuncture & moxibustion for 300 years. This book is composed of 10 chapters dealing almost all the medical theories of that times. This book is so enormous that it is hard to understand essential ideas of author. The reading medical records is one of the best way to develop one's abilities of curing a disease without clinical practice. so we can't help dealing with medical records, because it is one of important method of understanding Oriental Medicine. On this study, we investigate a objective method on understanding medical records in "Chimgudaeseong(鍼灸大成)".

In this study, medical images, which are X-ray image and CT image, are compressed by the adam live coding technique. The medical images may be treated as special ones, because they are different from general images in many respects. The statistical characteristics that medical images only have in transform domain are analyzed, and then the improved quantization method is proposed for medical images. For chest X-ray image and CT head image, the better results are obtained by the improved adaptive coding technique.

Determining cell quantity is a common problem in cytology research and anti-tumor drug development. A simple and low-cost method was developed to determine monolayer and adherent-growth cell quantities. The cell nucleus is located in the cytoplasm, and is independent. Thus, the nucleus cannot make contact even if the cell density is heavy. This phenomenon is the foundation of accurate cell-nucleus recognition. The cell nucleus is easily recognizable in images after fluorescent staining because it is independent. A one-to-one relationship exists between the nucleus and the cell; therefore, this method can be used to determine the quantity of proliferating cells. Results indicated that the activity of the histone deacetylase inhibitor Z1 was effective after this method was used. The nude-mouse xenograft model also revealed the potent anti-tumor activity of Z1. This research presents a new anti-tumor-drug evaluation method.

Objectives : Recently, the interest on medical education in flipped learning has been growing. Competency-based curriculum is also required through changes in teaching methods within the Korean medicine education. In this study, flipped learning method was applied to 'medical ethics' class to examine the perception and experience of flipped learning from the Korean medical student's perspectives. Methods : The study was conducted on 15 preparatory course freshmen students who took the 'medical ethics' course, in the second semester of the year 2017 at 'A' University. The study was proceded in two steps; 1) fill-in the questionnaire twice (before and after the class), and 2) in-depth interview with semi-structured questionnaire. The $1^{st}$ questionnaire in the first step was consisted of 'Experience on flipped learning before the class', 'Which section of the flipped learning class do participants have expectation', 'Interest and expectation on flipped learning'. In the $2^{nd}$ questionnare, the participants were asked 'Which section of the flipped learning section that the learning effect was maximized', 'Association between 'flipped learning' method and 'Medical ethics' course' with 5-point Likert scale and frequency. Results : The results showed that flipped learning method works very effectively in the 'medical ethics' course (63.6%). After the flipped learning class, the participants showed positive change in a attitude of the class (72.7%). However, this teaching method might be inappropriate for participants who had difficulties in pre-learning or a passive attitude and lecture-centered instruction (LCI) classes. Conclusions : Though applying flipped learning method to the 'Medical Ethics' was effective, to make pre-learning better, the instructors should prepare countermeasures for passive participants, help interact well among the participants, and plan a lesson thoroughly for changing LCI classes to student-centerd instruction(SCI).
