임베디드 보드 기반의 교육용 차동 구동 로봇 플랫폼 개발

최현주,이동현,Choi, Hyeon-Ju,Lee, Dong-Hyun 대한임베디드공학회 2022 대한임베디드공학회논문지 Vol.17 No.2

This paper proposes a mobile robot platform for education that can experiment with various autonomous driving algorithms such as obstacle avoidance and path planning. The platform consists of a robot module and a remote controller module, both of which are based on the Arduino Nano 33 IoT embedded board. The robot module is designed as a differential drive type using two encoder motors, and the speed of the motor is controlled using PID control. In the case of the remote controller module, a command to control the robot platform is received with a 2-axis joystick input, and an elliptical grid mapping technique is used to convert the joystick input into a linear and angular velocity command of the robot. WiFi and Zigbee are used for communication between the robot module and the remote controller module. The proposed robot platform was tested by measuring and comparing the linear velocity and angular velocity of the actual robot according to the linear velocity and angular velocity commands of the robot generated by the input of the joystick.

(110) 배향 TiO$_2$ 단결정 위에 성장시킨 CrO$_2$(110) 박막의 결정 구조, 미세구조와 자기적 특성의 상관 관계에 대해 연구하였다. 소스 물질로는 CrO$_3$ 분말을 사용하였으며, 열분해 화학증착법으로 CrO$_2$박막을 형성하였다. (110) 배향된 TiO$_2$루타일 단결정 위에 형성된 CrO$_2$ 박막은 (110) 방향으로 우선 배향되었고, 미세구조적으로 평활한 박막을 형성하였다. 흘려주는 산소량이 많을수록 CrO$_2$ 박막의 두께가 두꺼워지고 저항치가 낮았으며, 음의 자기저항치의 변화 및 자기 이력 곡선에서 보자력과 잔류 자화 값이 감소하는 경향을 보였다. We report the magnetic properties, microstructures, and crystal orientations of the CrO$_2$ thin films on TiO$_2$ single crystals. CrO$_2$ thin films were deposited by thermal decompositions with CrO$_3$ source materials. The microstructure of (110) oriented CrO$_2$ thin films deposited on (110) TiO$_2$ single crystals were uniform. As the oxygen flow rates increased, the resistivity, coercive field, and remnant magnetization of the CrO$_2$ thin films on TiO$_2$ single crystals decreased.

Even up to now, there are a lot of rhetoric words attached to the name of Seung-hee Choi (Nov. 24, 1911~Aug. 8, 1969), a Korean woman modern dancer. Her name is still re-titled with complimentary expressions such as ``Legend of Oriental Dance``, ``Dancing Girl of Korean Peninsula``, ``Flower of Joseon``, ``World-famous Dancer``, ``Legendary Woman Dancer`` and ``Immortal Woman of Myth.`` Choi developed her remarkable career of dancer across many international regions including Korea, Japan and Europe in the age of colonized Korea under the rule of Japanese imperialism. She lived her life with fetters of sorrow and pleasure till she went to North Korea with her husband. In the history of modern Korea, Choi is recognized as a rare figure of modern Korean woman who extended the boundary of her career into movie actress, singer and fashion model beyond dancer. A great number of conventional academic studies on Seung-hee Choi can be found in dancing and literature world, but most of those studies have focused primarily on artistic life, orientations, achievements and activities of Choi as well as her philosophical values. Based on the life story, artistic activities and critical biography of Choi, this study intends to take a new approach of art marketing to exploring her artistic achievements and values. The perfection of a performing art work is still valued so much as a means of creating audience value from its performance on stage, but the importance of multilateral promotions and novel planning is not to be overlooked. Whether Choi adopted such a planning and marketing means intentionally or unintentionally, her performing art activities demonstrate that she surely tried to promote herself by other means than perfection and value of a performing art work, and really wanted to get her performing art recognized by audience and make her dance known to more people. Thus, this study sought to take a new approach to the original artistry of Choi from the viewpoint of performing art planning and art marketing. Based on lots of existing academic literatures on Choi, this study attempted to define her identity as a s ort of brand and goods in the aspect of modern strategic planning, and took an approach of strategic planning to further examination into her artistic achievements, values and features on the basis of SWOT analysis.

만 3세 유아들의 산책활동에서 나타나는 창의성에 관한 사례연구

최현주(Choi Hyun Ju) 숭실대학교 영재교육연구소 2015 Global Creative Leader Vol.5 No.1

본 연구는 만 3세 유아들이 산책활동을 하는 동안 창의성이 어떻게 발현되고 계발 될 수 있는지를 사례연구를 통해 밝혀 보는데 목적을 두고 무선으로 선정한 어린이 집의 종일반 만 3세 유아 3명을 대상으로 연구를 진행하였다. 유아들의 산책활동에 서 나타나는 창의성을 이경화(2014)가 개발한 “유아용 통합 창의성 검사”의 하위요 소를 관찰범주로 사용하여 참여관찰을 통해 자료를 수집하고 분석하였다. 연구 결과 자연에서의 산책활동을 통해 유아의 창의성이 발현되고 계발 될 수 있다는 결과를 도출하였다. 즉, 도심에서의 일상적인 산책활동도 유아의 창의적 교육활동으로 활용 될 수 있다는 점을 시사한다. 첫째, 구조화된 놀잇감을 가지고 놀 때 보다 상징놀이와 창의적인 놀이가 증가하면서 상상력, 유창성, 융통성, 독창성, 등 창의적 능력이 발현됨을 알 수 있었다. 둘째, 창의적 성격은 창의적 능력과 서로 상호작용하면서 호기심, 독립심, 과제 집찹력은 후기로 갈수록 늘어나는 반면 모험심은 초기에 활발하였다가 중기에 줄어들었고 후기에는 다시 늘어났다. The purpose of this study was to find out 3 years old child's creativity during walking activities. A qualitative case study was conducted to the subjects that consisted of three children of age 3. The following research question was proposed in this study. Under the topic of "How is the creativity of a three year old child shown during their walking activities?", the study sought to find out what kind of creativity was shown and could be developed during walking activities of children through this case study. The subjects of this study were three randomly chosen children out of 15 children. The children were from age three class from "B" kindergarten located in Gangnam-Gu, Seoul. To examine the creativity that was shown during children's walking activities, the 'observation' context from "Integrated Creativity Test" developed by Lee(2014) was used. The data were collected from children's observation journals, pictures, movie clips of children's walking activities and the data were used to describe and analyze children's creativity. The results of the study were as follows: First, after observing the creativity of children shown during the walking activities, children showed more imagination skills, language fluency, flexibility and creativity and those abilities were developed further as time progressed. These results were due to the symbolic and creative play by children in the nature-environment where children found creative things to play with, out in the wild rather than fixed toys indoors. Second, as the study looked into the creative personality that was shown during children's walking activities, creative personality interacted with creative ability increasing curiosity, independency and task-commitment as it progressed to the latter period. However, adventurous spirit was lively in the beginning, but diminished in the middle period and increased again in the latter period. This was due to the stability that the location-oriented walking activities provided and activities were more vibrant at this stage. As it progressed to the latter period, the scenary changed affecting children's curiosity which in turn increased children's adventurous spirit. According to the study, it could be concluded that walking activities in the nature developed children's creativity. Thus, if walking activities in the nature are applied in the education field to children of all ages, in a specific, systematic and continuous manner, it could develop children's creativity. Especially in the follow-up study, the walking activities in the nature should be applied to children younger and older than age of three and an extended study of integrated education through walking activities should be conducted.
