Breast cancer is among the cancers that may be healed as the disease diagnosed at early times before it is distributed through all the areas of the body. The Automatic Analysis of Diagnostic Tests (AAT) is an automated assistance for physicians that can deliver reliable findings to analyze the critically endangered diseases. Deep learning, a family of machine learning methods, has grown at an astonishing pace in recent years. It is used to search and render diagnoses in fields from banking to medicine to machine learning. We attempt to create a deep learning algorithm that can reliably diagnose the breast cancer in the mammogram. We want the algorithm to identify it as cancer, or this image is not cancer, allowing use of a full testing dataset of either strong clinical annotations in training data or the cancer status only, in which a few images of either cancers or noncancer were annotated. Even with this technique, the photographs would be annotated with the condition; an optional portion of the annotated image will then act as the mark. The final stage of the suggested system doesn't need any based labels to be accessible during model training. Furthermore, the results of the review process suggest that deep learning approaches have surpassed the extent of the level of state-of-of-the-the-the-art in tumor identification, feature extraction, and classification. in these three ways, the paper explains why learning algorithms were applied: train the network from scratch, transplanting certain deep learning concepts and constraints into a network, and (another way) reducing the amount of parameters in the trained nets, are two functions that help expand the scope of the networks. Researchers in economically developing countries have applied deep learning imaging devices to cancer detection; on the other hand, cancer chances have gone through the roof in Africa. Convolutional Neural Network (CNN) is a sort of deep learning that can aid you with a variety of other activities, such as speech recognition, image recognition, and classification. To accomplish this goal in this article, we will use CNN to categorize and identify breast cancer photographs from the available databases from the US Centers for Disease Control and Prevention.

Although a call for the implementation of PBL in nursing education is getting increased, it has not been actively implemented as it could be. The main reason for this situation seems to be the lack of well designed learning packages. Well designed PBL packages can be the core factor for the successful implementation of PBL. However, this seems to be the hardest task for teachers wanting to implement PBL. Therefore, the purpose of this study is to develop a systematic framework of PBL package development process and provide the examples of its application. This framework of the process of PBL package development includes thirteen steps. First of all, the team needs to decide a topic to be explored in the package and then clusters concepts related to the topic. Second, the team selects a real situation and writes it as a story. Third, knowledge, skills, and attitudes that practitioners need to know to deal with the situation will be explored. Fourth, learning objectives will be written. The next, the team will check if the situation includes multidisciplinary concepts and content. Sixth, the story will be divided into several parts. Seventh, part 1 will be written. Eighth, clinical documents related to part 1 need to be prepared. Ninth, the team will write a suggested approach for students. Then, they need to prepare a tutor's guide for part 1. Eleventh, the team will prepare a list of reading materials and plan for lectures and clinical laboratory sessions. Twelfth, they will write part 2 ~ part N following the steps from the seventh to the eleventh. The last step is evaluating the package and amending it as needed. These thirteen steps are very detailed and easy to follow for beginners. It is expected that this framework will contribute to accelerate the implementation of PBL in nursing education.

이 연구에서는 다중 표상을 활용한 화학 개념 학습에서 연계 오류 감소를 위한 처방적인 교수 전략의 효과를 학생들의 장독립성-장의존성에 따라 조사했다. 남녀공학 중학교 1학년 126명을 통제 집단과 처치 집단으로 배치한 후, '보일의 법칙'과 '샤를의 법칙'에 대해 2차시 동안 수업을 진행했다. 연구 결과, 개념 이해도 검사에서 처치 집단의 점수가 통제 집단의 점수보다 통계적으로 유의미한 차이로 높았다. 학습 동기 검사에서는 학습 동기 전체와 하위 영역 중 '주의집중' 영역에서, 처치 집단 학생들의 점수가 통제 집단 학생들의 점수보다 통계적으로 유의미한 차이로 높았다. 그러나 두 검사에서 모두 수업 처치와 장독립성-장의존성 사이의 상호작용 효과는 없었다. 처치 집단 학생들의 대부분이 새로운 교수 전략에 대해 인지적, 동기적 측면에서 긍정적으로 인식하는 것으로 나타났다.

This research was to understand the features of mathematization and didactical phenomenology, in a way that was not a routine calculation of equation, rather a complete comprehension by the reinventing historical principles of the equation. To achieve the purpose of this study, one-mate middle school student participated in the study. Interview and observation were used for collecting data during the student's performance. The results of research were: First, the student understood the mathematical concepts from a real life and developed the abstract concepts from it, which were very intimately related with his life. Second, the skill and formula definition were accomplished with the accompanying predicted and consequently derived mathematical concepts. Third, through the approach of using the history of mathematics, he became more interested in what he was doing and took lessons with confidence. Forth, the student performed his learning based on the historical reinventing principle under the proper guidance of a teacher.

Athletic products must meet the needs of athletes and the demands imposed by sports through innovative design. These needs of athletes and requirements of sports are performance, protection and comfort related. In depth knowledge of anatomy and physiology, etiology of commonly reported injuries, and lower extremity mechanics form the basis of product creation/engineering. Game analysis which entails time and frequency surveys of the skills performed during a game, interviews with athletes and coaches, and discussions with medical staffs are used to identify the skills that are critical to the needs of athletes. In lab full biomechanical analyses of these skills and/or physiological responses of the athletes lead to clear functional criterions that serve as guidelines to be met by the design team. The concepts created by the design team are in turns subjected to the same battery of biomechanical analyses. The learning gathered through this pluridisciplinary process is used to further evolve design concepts. The evolution-testing loop is repeated until biomechanical and/or physiological, mechanical and perceptual tests indicate that the design concept meets the established functional design criterions. At that time, the design concepts is ready for manufacturing research and development. Additional biomechanical and physical tests are performed through that phase to confirm that the manufacturing processes preserve the functionality of the design concept. Durability and long term performance of production samples are evaluated through a final three month long weartest program. A rigorous research/testing program is crucial to create and engineer sport products that meet the performance, protection.

The purpose of this study was to investigate elementary student teachers' conceptions about the mechanism of the greenhouse effect, the greenhouse gases, the global warming, and their learning experiences of the greenhouse effect and the global warming. Participants were 82 student teachers in their second year of studies (science education: n=28, not science education: n=27) and in their fourth year of studies (science education: n=27). The open-ended questionnaire was used to examine the teachers' spontaneous ideas depicted by their drawings and/or writings. The results of this study are as follows: First, the student teachers' scientific response rate about key concepts related to the mechanism of the greenhouse effect was low (6.1%~28.0%); Second, although there are various greenhouse gases, it was only carbon dioxide that the student teacher's response rate was more than 80%; Third, only 17.1% of the student teachers clearly distinguished the greenhouse effect and the global warming; Fourth, there was a tendency that the student teacher group in the fourth year of studies and science education showed higher scientific response rate about the concepts than the other two groups.
