현행 기하와 벡터 교과서에는 타원 방정식을 통해 초점, 꼭짓점 등을 구하는 기계적 활동이 주가 되어 있어 본 논문에서는 좌표평면과 식 없이 주어진 타원 그래프로부터 초점 작도를 하는 가역적 활동에서 유추와 분석적 방법이 활용되는 과정을 연구하였다. 탐구 도구는 Geogebra를 활용하였으며 처음 학생들은 주어진 타원에서 장축, 단축을 임의로 작도하여 타원의 초점을 찾으려는 오류를 범하였다. 하지만 원의 대칭축을 작도하는 방법을 경험하고 이 원리를 분석하여 타원에 유추한 결과 타원의 중심과 장축, 단축을 작도할 수 있었다. 이후 초점 작도 과정에서 분석적 방법을 활용하여 초점 식을 피타고라스 정리로 인식하여 원의 작도 활용해 타원의 초점 작도를 하였다. 따라서 타원 초점 작도에서 유추와 분석적 방법이 긍정적으로 작용할 수 있음을 확인하였다.

Today, further education of adults in the UK is one of the developing areas of continuing education. The Open University with distance learning, in the process of which innovative forms and methods based on computer and telecommunication technologies are used, is particularly successful in the organization of additional education of the adult population. The advantages of distance learning, multimedia - the latest information technologies, which provide the combination of graphic images, video, sound with the help of modern computer tools, are noted. The basic principles and forms underlying the technologies and forms of work with the elderly are defined. The international experience of implementing "Universities of the Third Age" is summarized. The most widespread approach in adult education in Great Britain is informational. The use of computer technologies motivates a new paradigm in educational methods and strategies, which requires new approaches, forms of learning, and innovative ways of delivering educational materials to adult learners. Information technologies have gained great popularity in such activities as distance learning, online learning, assistance in the education management system, development of programs and virtual textbooks in various subjects, online search for information for the educational process, computer testing of students' knowledge, creation of electronic libraries, formation of a single scientific electronic environment, publication of virtual magazines and newspapers on pedagogical topics, teleconferences, expansion of international cooperation in the field of Internet education. The information technology of synchronous distance learning "online" has gained considerable popularity in the educational process today. A promising direction is the use of multimedia technologies in educational activities to create a design of a virtual computer environment by decoding audiovisual information.

Junior Ranger is a self-directed interpretation program for young visitors at national parks in the United States. The success of this program can be largely attributed to the role of an activity book which is given an applicant free of charge at a visitor center. This study aims to analyze the main characteristics of activity books for 14 national parks' Junior Ranger and to draw some implications for Korean geomorphological education. Although the activity books are varied in size, volume and printing, all of them offer diverse activities which are composed of different contents related to park resources in four fields and are performed in different ways such as Q&A, picture and word game, and creative activity. The time-consuming activities including attendance at a ranger-led program prevent the participant from making a superficial visit to be a junior ranger. The implications of the study are as follows: Firstly, the geomorphological education for children is needed to be strongly based on field experience learning and to be more carried out using a way of game rather than conventional Q&A, suggesting that it encourages students not to lose their interest for learning. Secondly, it is also necessary for the learning contents to be focused on various resources related to landform as well as landform itself. In addition, a creative activity such as writing verse or drawing feeling should be more applied to the geomorphological education in order to enhance their effects on affective domain beyond cognitive one. It is likely to be an alternative approach to understand landform by internalizing a sense of landform.

The biggest change in the current medical service market is the shift from producer-based approach to customer-based approach. Thus, there is a high necessity for an introduction of market-oriented and customer-oriented marketing activities in medical institutions. Especially, revisitation and positive word-of-mouth of customers are the most effective marketing methods of consistently obtaining customers and drawing new loyal customers. Hence, the factors influencing the reuse of medical services and word-of-mouth are demonstrated using SERVQUAL, and the results show that the service factors influencing reuse intentions on medical services are assurance, responsiveness, and tangibles and the factors strengthening word-of-mouth are empathy and assurance on the services provided by medical institutions. This study has determined that revistation and word-of-mouth of customers are not only influenced by satisfaction on medical services but by the quality itself as well. Therefore, medical service providers need to pursue standardized strategies in order to enhance the quality of medical services simultaneously in addition to simply increasing the customer satisfaction level.

Endophytic fungi are microorganisms inhabiting living plant tissues without causing apparent harm to the host. They are drawing increasing attention due to their ability to produce various bioactive compounds as well as their effects on host growth and resistance to biotic and abiotic stresses. As a first step to assess biodiversity of plant associated fungi in Korea and the following evaluation on diverse biological activities, we are collecting endophytic fungi from plant in wild followed by systematic long-term storage in liquid nitrogen. Molecular identification using ITS sequences was also incorporated for pure culture by hyphal tip isolation. As of April 2015, about 1,400 fungal strains had been isolated from about 170 plant taxa. Fungal isolates belonging to Pleosporales, Diaporthales, Glomerellales, Hypocreales, and Xylariales were the most abundant. These collections are being used for several complementary researches, including screening of isolates with novel bioactive compounds or conferring drought stress resistance, phylogenetic and genomic study. Genome sequencing was performed for 3 isolates, one Xylaria sp. strain JS573 producing griseofulvin, an antifungal compound, and two Fusarium spp. strains JS626 and JS1030, which are assumed to be new species found in Korea. More detailed analysis on these genomes will be presented. These collections and genome informations will serve as invaluable resources for identifying novel bioactive materials in addition to expand our knowledge on fungal biodiversity.

Due to the lack of available site in urban setting outdoor space in elementary schools are getting smaller and tend to be replaced by indoor spaces. Focusing on courtyard, piloti space and roof space, this study analyzed the current condition and usage of the outdoor spaces in the urban mini-schools based on the analysis of architectural drawing, interview, survey, and observation. Following issues are found for appropriate planning for outdoor spaces in the urban mini-schools. Firstly, roof space needs to be coordinated with the physical education and outdoor class curriculum and should be planned separately for quiet activities. Secondly, the piloti space should be planned as an independent space rather than a connection between classroom and outdoor space, with appropriate surveillance from teacher's space for the lower graders. Thirdly, courtyard space, typical space in urban mini school surrounded by densely arranged buildings, should be thermally controlled for outdoor class or resting with appropriate screen from noise to keep quiet atmosphere.

This study focuses on the technology to reduce destruction and damages of an ecosystem in the process of road construction. The authors investigated the ecological conservation activities and restoration technology which were applied to the construction of 2 bridges in Japan. The key results are as following : First, the most important thing in constructing eco-road was the linear design. Second, we need to adopt the environmental construction forms and materials to the design of structure. Finally, we have to use environment-friendly methods for the sake of the ecosystem at the real construction stage. Adopting those technologies has at least a few merits. First, we can achieve out goals : conservation and restoration in the local habitat. Second, we can save money instead of building a eco-bridge. There is a further advantage which makes it possible to develop environment-friendly technologies than before by drawing developers' attention.

Purpose: The purpose of this study was to compare the electromyographic activity and onset time of the gluteus maximus (GM) and hamstring (HAM), lumbopelvic kinematics during three different prone table hip extension exercises in healthy individuals. Methods: Twenty subjects were participated. Electromyography device was used to measure the muscle activities and onset time of the GM and HAM muscles. An electromagnetic tracking motion device was used to measure lumbopelvic compensations. The subjects were asked to perform three different prone table hip extension [Prone table hip extension with the abdominal drawing-in maneuver on a chair (PTHEA), PTHEA with the ipsilateral knee flexion (PTHEAF), PTHEAF with hip 30 abduction (PTHEAFA)]. One-way repeated measures analysis of the variance and a Bonferroni post hoc test were used. Results: The electromyographic activity and onset time were significantly different among three conditions (PTHEA vs. PTHEAF vs. PTHEAFA)(p<0.01). The GM muscle activity and onset time were significantly greater and reduced during the PTHEAFA compared to PTHEA and PTHEAF (p<0.01). However, The HAM muscle activity and onset time were significantly smaller and delayed during the PTHEAFA compared to PTHEA and PTHEAF (p<0.01). Conclusions: PTHEAFA exercise can be recommended to facilitate the muscle activity and efficient muscle firing time of GM without HAM dominance.
