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.

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.

Purpose: This study was conducted to examine the degree of suicidal ideation, social support and self-esteem on depression in middle school students. Methods: The study, based on a correlation study design, selected participants from five middle schools by convenience sampling. Data were collected from April 19 to June 13, 2015 from the 427 participants included in the study. The data were analyzed using SPSS / Win 20.0. Results: There was a significant correlation between depression, self esteem, social support, and suicidal ideation. Depression was negatively correlated with self-esteem(r=-.47, p<.001) and social support(r=-.45, p<.001), while being positively correlated with suicidal ideation(r=.64, p<.001). Conclusion: The findings indicate that depression in middle school students can increase the risk of suicide. Self-esteem and social support of middle school students are also important resources for reduce depression and suicide prevention.

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.

화법의 교수,학습 방법 ; 대중 의사소통의 특성과 교육 방법

이도영 ( Do Young Lee ) 한국화법학회 2010 화법연구 Vol.0 No.16

현재의 대중 의사소통 교육은 화법 교육에서 그다지 주목을 받지 못하고 있다. 그러다 보니, 대중 의사소통 교육은 보편적인 언행적 목적 추구에만 관심을 갖게 되고 일반적인 언어 사용의 심리적 과정에만 치중하고 있다. 대중 의사소통 교육 고유의 교육 내용과 방법이 거의 없다고 해도 과언이 아닐 것이다. 본고는 이러한 문제를 해결하기 위해 먼저 대중 의사소통이 다른 유형의 의사소통과 어떻게 같고 다른지를 의사소통 구성 요소 별로 비교, 검토하여 대중 의사소통의 특성을 걸러내었다. 그런 다음 대중 의사소통의 특성에 맞는 교육 목표와 내용, 방법에는 어떤 것들이 있는지 살펴보았다. 대중 의사소통의 본질적 목표가 설득에 있다면, 대중 의사소통 교육의 목표는 학생들에게 청중을 설득할 수 있는 능력을 갖추게 하는데 있다. 하지만 이는 화자의 입장에서만 타당하므로 청자의 입장에서도 대중 의사소통 교육의 목표를 세울 필요가 있다. 청자의 경우에는 일단 화자의 생각, 견해, 의견, 주장, 근거 등을 객관적으로 들을 필요가 있다. 그런 다음에 화자와 공유할 만한 것과 그렇지 않은 것을 가려내고, 이를 청자의 생각과 융합하여 청자 자신의 생각이나 견해, 의견, 주장 등을 형성할 수 있어야 한다. 이를 위해서는 비판적 듣기가필수적이다. 대중 의사소통 교육에서 가르쳐야 할 내용 역시 화자와 청자로 나누어 살펴볼 수 있다. 화자 입장에서는 `청중 분석, 내적 의사소통, 메시지 선정과 조직, 논증 방법, 설득 방법, 메시지 소구 방법, 표현과 전달, 소통의 윤리성`등을 가르쳐야 한다. 청자 측면에서는 `화자 분석, 내적 의사소통, 메시지 분석, 화자의 표현과 전달 분석, 비판적 듣기` 등이 필요한 교육 내용이 된다. 대중 의사소통의 교육 방법은 이해와 표현을 이중적으로 결합한 형태가 된다. 이해 Ⅰ은 대중 의사소통 담화의 유형을 익히는 단계이다. 학생들에게는 대중 의사소통이라는 담화 유형이 낯설기 때문에 이처럼 담화 유형을 이해하는 것부터 출발해야 한다. 주된 활동은 담화를 분석해 봄으로써 효과적인 대중 의사소통 담화란 어떤 것인지를 이해 하고, 이를 표현에 활용하는 것이다. 표현 단계에서는 메시지 선정, 조직, 표현, 전달 등 담화 생산과 관련된 제반 활동을 가상의 청중을 대상으로 실제로 해 보는 것이다. 이해Ⅰ에서 배운 것과 관련지으면서 활동을 하되, 원고를 써 보는 활동을 포함시킨다. 이해 Ⅱ에서는 동료 학생들의 대중 의사소통 관련 담화를 듣고 이를 객관적이면서도 비판적으로 이해하는 것이다. 기초적인 듣기 방법은 이해Ⅰ에서 배우고, 이해Ⅱ 단계에서는 실제적인 듣기 능력을 기르는 것이다. 이와 같은 구도는 대중 의사소통을 통해 듣기, 말하기, 읽기, 쓰기 등을 통합해서 가르칠 수 있다는 장점이 있다. The education of public communication doesn`t become an object of attention. As a result, the education of public communication is more interested in pursuit of general speech act purpose and psychological process of language use. To solve these problems, first we need to derive the properties of public communication, and then to establish the aims, contents, methods of public communication`s education. The aims of public communication`s education is to develop the persuasion abilities of students. Also speaking as listener, students can objectively and critically listen speaker`s thoughts, viewpoints, opinions. The contents of public communication`s education is also divided into speaker and listener. Students as speaker must know the analysis of audience, the self in communicaton, the selection and organization of messages, the method of argumentation and persuasion, message appeal, expressions and dliveries, communication`d ethics. Also students as listener must know the analysis of speaker, the self in communicaton, the analysis of messages and speaker`s expressions and dliveries, the method of critical listening. The methods of public communication`s education should become the double combination`s formation of expression and comprehension. Comprehension Ⅰ is the stage for students to master the type ofpublic communication discourse. The main practice of this stage is to analyse public communication discourse. In the stage of expression, students try to actually communicate to simulated audience including the writing of public communication discourse. In the stage of comprehension Ⅱ, students must listen carefully peer students`s communication and understand objctively and critically it`s messages. These designs of public communication`s education have advantages to teach speaking, listening, reading, writing integratively.

건축설계 학습부진자들의 건축적 사고 개선을 위한 데모 기반 설계수업 운영모형 개발 및 활용 사례연구

이도영(Lee, Do-Young),정현미(Chung Hyun-Mi) 대한건축학회 2020 대한건축학회논문집 Vol.36 No.3

Based on Merrill’s instructional theory, this study pursued to develop a demonstration-based architectural design class operation model for the 3<SUP>rd</SUP> year undergraduate students taking a Spring semester design studio class. The model was designed and used particularly to improve architectural thinking abilities of under-motivated learners. Learning effects of the model were examined based on the preliminary data obtained for 3 consecutive years, 2017 through 2019. A total of 52 students were participated in the class and observed by the instructor. Once developed, the model has been continually updated and improved based on results of each class operation. Five types of demo. were used in the model. First, direct contacts of the instructor with under-motivated learners were turned out to be the most preferred demo(demo. 4), while watching and listening of the demo(demo.3) between the instructor and motivated learners taking place in class was ranked at the second place. Belief of under-motivated learners on the instructor as a professional should be highly valued for improving their architectural thinking abilities. Second, motivated peers’ direct help for under-motivated ones was placed in the third rank. Social attitudes of under-motivated learners towards accepting motivated ones’ helps were determined the particular demo’s appropriateness. Third, a set of guidelines for operating the model in undergraduate design studio classes were developed and suggested.

This study proposes to develop an integrated class operational model for training architecture-based professionals of public design on an undergraduate level, and then apply it to a 3rd year design studio course of ‘A’ university held in Fall semester 2013. Basically, it is assumed that two different levels of integration occur simultaneously in the study. One is related to integration by academic realms that are representative of architecture and public design, while the other is integration by types of thinking to be inclusively developed in class via the design education process. In order to scrutinize the first level of integration, a conceptual framework developed in 2013 for architecture-based public design education was used. The second level of integration, additionally, is related to a test if an ability of both problem understanding and solving necessary for rchitecture-based public designers can be improved by integrating a variety of types of thinking used practically in the on-going design process. Based on understanding of Bloom’s 6 stages of extended thinking process(recognize, understand, apply, analyze, synthesize, evaluate), a 6 set of problems were developed and used for task performance. Three teams composing of 4 students for each were asked to solve their problems in the revised Bloom"s 5 consecutive thinking process; (1)presentation of personal solutions resulted from team activities, (2)critique or analysis of each individual member’s work in a team, (3)preparation of a synthesized best alternative based on the critique or analysis, (4)evaluation on the overall working process at a team level, (5)preparation and submission of final output sheets. Each problem was supported by relevant guiding questions to help teams to work out in a right and effective direction. Results of the study show that an integrated approach of this sort to raising architecture-based public designers is likely to have a highly positive effect on increasing the possibility.
