  • The purpose of this study is to analyze the questions generated by elementary school pre-service teachers when reading the teacher's guide for the refraction of light, and to analyze the difficulties in understanding the concept and in making instructional plans. A total of 592 meaningful questions were generated by 283 elementary school pre-service teachers after reading the teacher's guide of 'light and lens' unit in the 6th grade of the 2015 revised curriculum. Of these, 306 questions are for understanding the concept of physics and 286 are pedagogical questions. As a result of the analysis, in terms of understanding the concept of physics, the elementary school pre-service teachers encounter difficulties in understanding the concept of the 'cause' of the phenomenon suggested in the textbook, such as the cause of refraction, the reason for scattering light, and the cause of the image change depending on the focal length of the convex lens. In terms of instructional planning, it was followed by questions about how to explain concepts, questions about not being able to explain concepts to elementary school students and having to teach only phenomena, specific explanation methods for specific concepts, and experimental methods. Although the teacher's guide contains various explanations and supplementary materials to help teachers understand the concept, it can be seen that there are many elementary pre-service teachers who cannot answer questions about some concepts even after reading the guide. For concepts with a high frequency of questions, it is necessary to prepare a tutorial that is more understandable. In the instructional plan, there were many questions about teaching methods and experimental methods, so it is necessary to provide more examples and specific experimental methods for explaining concepts in the teacher's guide.

  • Theoretical framework of motor learning is used to enhance perceptual motor skill in physical therapy intervention, which can be subdivided into two main types-explicit and implicit. The purpose of this study was to examine whether stroke patients with unilateral brain damage learn implicitly a motor skill using the arm ipsilateral to the damaged hemisphere. Speculation then followed as to the formation of therapeutic plans and instructions provided to patients with stroke. 20 patients with stroke and 20 normal participants were recruited. All the subjects practiced serial reaction time tasks for 30 minutes a day and retention tests on the following day. The tasks and tests involved pressing the corresponding buttons to 4 colored circles presented on a computer screen as quickly and accurately as possible. Patients with stroke responded more slowly than controls. However, both groups showed decreased reaction time in the experimental and retention periods. Also, there was no significant difference between both groups regarding explicit knowledge of consecutive order. Therefore, patients with stoke had the ability to learn implicitly a perceptual motor skill. Prescriptive instruction using implicit and explicit feedback may be beneficial for motor skill learning in physical therapy intervention for patients with brain damage.

  • Objectives: The purpose of this survey was to investigate the need for new medical devices based on opinions of members of the Korean medical society. Methods: We distributed two independent questionnaires sequentially over two-week intervals to 16,510 doctors via the Korean Medical Society, and received replies from 888 and 928 doctors, respectively. The survey was carried out through a web-based questionnaire system. The first questionnaire focused on demand for new diagnostic and therapeutic medical devices that are specific for Korean medicine (KM). In contrast, the second questionnaire focused on demand for new hybrid medical devices which are useful both in Western medicine (WM) and KM. Results: In purchase intention of Korean medical devices (KMDs), demand for diagnostic devices was greater than for therapeutic ones. Among diagnostic devices, the purchase intention of 'imaging devices' ranked the highest and was followed by 'musculoskeletal diagnostic devices'. Among therapeutic KMDs, the purchase intention of 'musculoskeletal treatment devices' ranked the highest, followed by 'cranial nerve rehabilitation devices'. In the purchase intention of hybrid medical devices that can be used both in WM and KM, 'ultrasonic-based medical device' ranked the highest, followed by 'MRI-based medical device'. Conclusions: There is increasing demand for clinically useful medical devices among Korean medical doctors. Within demand for new devices, hybrid devices that can be used in both WM and KM were most strongly desired. This survey will be useful in establishing strategic plans for the development of medical devices in KM. Keywords: Korean medicine, medical device, demand survey, questionnaire.

  • Since 2008, it has been stipulated to conduct programming education for grade 5 and 6 elementary school student. However, it is the reality that the plans and studies for this are seriously lacking until now. The objective of this study is to propose a programming education utilizing robots as a plan to overcome limitations of existing programming education, find the problems through developing and applying education program for general elementary school students. As a result of experimental application of the developed program, since the gap of academic accomplishment for the robot programming is large for each student, it is necessary to develop education program to enable individual studies of each level and operate program with the focus on programming education rather than the robot. Moreover, it is pointed that the difficult and unnecessary elements in the robot programming course must be improved or reduced, it is better to exercise it on the grade 6 program for concentration on the programming education, and there should be improvement on equipment, environment for robot programming.

  • Recently, the convergence of genre-mixed collaboration and technology-mixed collaboration in performance art strategically fuses different goals and different properties, satisfying anticipated demand, and developing into experimental forms that bring out convergence contents of new value. To supplement problems of convergence attempts and heighten levels of completion, the effective collaborative processes of media experts must be studied and improved. This thesis attempts to study effective collaborative production plans of convergence performance that correspond to the demands of the times through multimedia convergence performance prototypes(Live performance play + Pre-made digital animation). It categorizes performance production processes into pre-production and production and researches the effective collaborative production processes of convergence performances that utilize these two forms of media through work selection, production direction establishment, human resource constituents, production schedule plan establishment, visualization processes, and performance practices and rehearsals. Continuous research must be conducted based on convergence performance contents planning, changes in production methods, and an understanding of distinct characteristics among convergence contents for the industrial development systemization and vitalization of convergence contents to be made possible.

  • Ileal atresia, a subtype of intestinal atresia, is one of the well-recognized causes of bowel obstruction in newborns. Prenatal diagnosis of intestinal atresia is very important in its management and outcome. Unfortunately, there are few cases of ileal atresia diagnosed prenatally, so more appropriate diagnoses and management plans are needed. As an associated gastrointestinal malformation with ileal atresia, hypertrophic pyloric stenosis is rarely reported. We report one case of postnatally diagnosed ileal atresia associated with hypertrophic pyloric stenosis which was complicated initially by bowel perforation and later by vomiting due to pyloric obstruction. Vomiting in the postoperative period is a common problem. But, if vomiting continues after the operation for ileal atresia, hypertrophic pyloric stenosis should be considered as a possible cause of medically retractable non-bilious vomiting.

  • Since 1997, Dr. Shin-ya Nishimura has been developing an actual town planning project named the "Gangi Project". Students, inhabitants and local professionals walk around Omotemachi, examine the characteristics of the environment and the inhabitants' way of life, discuss plans and designs for traditional wooden arcades called locally "gangi". Students and inhabitants build the gangi together every year. The purpose of this study is to clarify how an experimental project aiming to preserve a living environment obtains sustainability as an actual town planning exercise. The research hypothesizes that sustainable town planning should include strategies for financial autonomy, active participation of inhabitants, supports from local professionals, an acceptance of changing environments, and responsible construction. The project has been carried out as a part of actual town planning, and continues to create a daily living environment based on the recent economical and industrial situation of the town. By focusing on the influences of the project on the town and inhabitants, the study has revealed the possibility of an actual town planning with small budget, and importance of a collaborative relationship with various participants in order to foster a sense of responsibility regarding the construction. The project also highlights the implication that sustainable town planning creates not only a participatory system but also a collaborative one in which participants take responsibility for the issues involved in the construction process.
