Mesoporous carbon nanofibers as electrode material for electrical double-layer capacitors(EDLCs) are fabricated using the electrospinning method and carbonization. Their morphologies, structures, chemical bonding states, porous structure, and electrochemical performance are investigated. The optimized mesoporous carbon nanofiber has a high sepecific surface area of $667m^2\;g^{-1}$, high average pore size of 6.3 nm, and high mesopore volume fraction of 80 %, as well as a unifom network structure consiting of a 1-D nanofiber stucture. The optimized mesoporous carbon nanofiber shows outstanding electrochemical performance with high specific capacitance of $87F\;g^{-1}$ at a current density of $0.1A\;g^{-1}$, high-rate performance ($72F\;g^{-1}$ at a current density of $20.0A\;g^{-1}$), and good cycling stability ($92F\;g^{-1}$ after 100 cycles). The improvement of the electrochemical performance via the combined effects of high specific surface area are due to the high mesopore volume fraction of the carbon nanofibers.

Traumatic dislocation of the peroneal tendon is an infrequent injury. This injury is caused by forceful dorsiflexion of the foot accompanied by a powerful contraction of the peroneal muscles. This mechanism of injury tears the superior peroneal retinaculum and allows the tendons to snap anteriorly. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by bone block surgery using autograft of lateral fibula and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.

Fluorine-doped tin oxide (FTO) nanoparticles have been successfully synthesized using ultrasonic spray pyrolysis. The morphologies, crystal structures, chemical bonding states, and electrochemical properties of the nanoparticles are investigated. The FTO nanoparticles show uniform morphology and size distribution in the range of 6-10 nm. The FTO nanoparticles exhibit excellent electrochemical performance with high discharge specific capacity and good cycling stability ($620mAhg^{-1}$ capacity retention up to 50 cycles), as well as excellent high-rate performance ($250mAhg^{-1}$ at $700mAg^{-1}$) compared to that of commercial $SnO_2$. The improved electrochemical performance can be explained by two main effects. First, the excellent cycling stability with high discharge capacity is attributed to the nano-sized FTO particles, which are related to the increased electrochemical active area between the electrode and electrolyte. Second, the superb high-rate performance and the excellent cycling stability are ascribed to the increased electrical conductivity, which results from the introduction of fluorine doping in $SnO_2$. This noble electrode structure can provide powerful potential anode materials for high-performance lithiumion batteries.

This study was aimed to understand the recognition of care robots which would enhance the medical quality of life under the 4^th industrial revolution in the university students majoring in health and engineering who would lead the development of the future medical industry and to find out the differences of their digital literacy and empathic ability. This was a descriptive correlation study to analyze the recognition of university students on care robots, their digital literacy and empathic ability. Both students majoring in health and engineering recognized the needs of care robots, while their education experiences were not sufficient. Moreover, statistically fewer university students majoring in health heard about care robots than those in engineering, and their need of taking classes was lower, too. No statistically significant differences were found in digital literacy and empathic ability between the two majors, while significant difference was found in the relationship bundling capability out of behavioral empathy, a sub-domain of empathic ability. The study results are anticipated to suggest the future educational direction in the medical field according to the 4^th industrial revolution and to be the fundamental data for understanding and preparation of the students depending on the majors. 본 연구에서는 4차 산업형명의 의료 삶의 질을 향상시켜줄 케어로봇에 대하여 미래 의료 산업 발전을 주도할 보건전공 대학생과 공학전공 대학생의 케어로봇에 대한 인식을 확인하고, 이들의 디지털 리터러시 및 공감능력의 차이를 확인하고자 하였다. 본 연구는 대학생의 케어로봇에 대한 인식과 디지털 리터러시 및 공감능력에 대해 분석하기 위한 서술적 상관관계 연구이다. 보건계열 대학생과 공학계열 대학생은 케어로봇에 대한 필요성을 인식하고 있었으나, 교육 경험이 두 군 모두 미흡하였다. 더욱이 보건계열 대학생의 경우 케어로봇에 대해 들어본 경험이 공학계열 학생보다 통계적으로 낮았으며, 수강 요구도 또한 낮았다. 보건계열 대학생과 공학계열 대학생의 디지털 리터러시는 통계적으로 유의한 차이가 없었고, 공감능력 통계적으로 유의한 차이가 없었지만 하위영역인 행동적 공감에서 관계형성능력은 통계적으로 유의한 차이가 있었다. 본 연구를 통하여 추후 4차 산업에 따른 의료 분야의 교육의 다학제간의 방향성을 제시하고 전공에 따른 학습자들을 위한 이해와 준비의 기초자료가 될 수 있기를 기대한다.

The purpose of this study is to design listening and speaking's teaching materials. For this purpose, we investigated the problems of current listening and speaking's elementary textbook. It has three main problems. First, it chiefly focuses on individual listening and speaking. Second, it lacks active and voluntary participation of students. Third, it only puts emphasis on the verbal purposes. To solve these problems, it needs to constitute the listening and speaking's teaching materials centering on communication. First of all, the beginning of its design plan is to select and organize the educational contents. And then it brings linguistic data of real life. At this time, teaching and learning methods to connect the contents and linguistic data become the important element of listening and speaking's teaching materials. Also, it weightily considers the media that delivers the contents and methods. And it thinks over the formation of student's participation.

This study proposes to investigate possibilities of utilizing constructivist approach to practice based professional training of university students in studio environments. Two fundamental ways of delivering the approach are recognized for the study; (1)Problem Based Learning(so-called PBL) and (2)Community of Practice(so-called CoP). PBL is a learning method for learners to motivate their ability of practicing by co-working with fellows under the same subjects and common rules as well. On the other hand, CoP can be defined as a practice based learning method for professionals with different abilities of solving problems but same objectives to improve professionalism of each in the community vie means of co-works and mutual interactions. Based on relevant literature reviews, a conceptual model for the study is developed as an analytical tool for the study. To prove its validity as applied to architectural design studios, a total of 41 studios projects delivered actually on 2005/6 academic years and particularly in the foundation and core programs of professional schools of architecture in U.S.A and U.K. are examined. They are (1)Southern California institute of architecture(so called ‘SCI-Arc’), (2)Cornell department of architecture, (3)Cooper Union school of architecture, (4)Pratt institute school of architecture in U.S.A., and (5)Bartlett school of architecture and Architectural Association school of architecture in U.K. Results of the study can be summarized as follows. First, problems are presented to students in a realistic and practical but non structured format. Second, team practice is planned to be frequently occurred to learn more on individual levels. Third, CoP activities actually take place as a variety of architectural professionals altogether are participated in CoP groups to solve a series of common problems. Fourth, diverse personal and material resources are provided for students to activate their CoP activities at different levels. Tutors work as a guider or coach for students to proceed project delivery in an effective and right way, while students are active workers who develop ideas and solve problems with professional minds of their own and professionals’ helps as well.

이도영(Lee, Do-Young) 대한건축학회 2018 대한건축학회논문집 Vol.34 No.3

This study pursued to obtain 3 consecutive purposes. First, a conceptual model for comparing 3 constructivist teaching and learning strategies(problem-based learning[PbBL], case-based learning[CBL] and project-based learning[PjBL]) was developed. Relationships of these constructivist strategies with the development of expertise for learners were discussed. Second, specific differences between PbBL, CBL and PjBL as applied in architectural design courses were analyzed under each of the teaching and learning category. Some analytical indexes were developed by content analysis, which are applicable effectively to reveal the differences. Based on the previous findings, third, a set of strategic guidelines for use in class were made and suggested in order to develop and improve expertise in architectural design. These guidelines were largely targeted for university design courses as well as education or reeducation of practicing architects. Expecially, combined application of PbBL, CBL and PjBL was hypothesized and suggested as class management guidelines. In sum, a variety of PbBL problems, CBL cases and PjBL projects should be developed for expecting audience based on design subjects and tasks. As working domains of practicing architects, exploring/analyzing, understanding/making applications, and criticizing/self-reflecting should be considered in the development process.
