  • Purpose : The object of this study was to examine the effect of motor learning on brain activation depending on the method of motor learning. Methods : The brain activation was measured in 9 men by fMRI. The subjects were divided into the following groups depending on the method of motor learning: actually practice (AP, n=3) group, action observation (AO, n=3) group and motor imagery (MI, n=3) group. In order to examine the effect of motor learning depending on the method of motor learning, the brain activation data were measured during learning. For the investigation of brain activation, fMRI was conducted. Results : The results of brain activation measured before and during learning were as follows; (1) During learning, the AP group showed the activation in the following areas: primary motor area located in precentral gyrus, somatosensory area located in postcentral gyrus, supplemental motor area and prefrontal association area located in precentral gyrus, middle frontal gyrus and superior frontal gyrus, speech area located in superior temporal gyrus and middle temporal gyrus, Broca's area located in inferior parietal lobe and somatosensory association area of precuneus; (2) During learning, the AD groups showed the activation in the following areas: primary motor area located in precentral gyrus, prefrontal association area located in middle frontal gyrus and superior frontal gyrus, speech area and supplemental motor area located in superior temporal gyrus and middle temporal gyrus, Broca's area located in inferior parietal lobe, somatosensory area and primary motor area located in precentral gyrus of right cerebrum and left cerebrum, and somatosensory association area located in precuneus; and (3) During learning, the MI group showed activation in the following areas: speech area located in superior temporal gyrus, supplemental area, and somatosensory association area located in precuneus. Conclusion : Given the results above, in this study, the action observation was suggested as an alternative to motor learning through actual practice in serial reaction time task of motor learning. It showed the similar results to the actual practice in brain activation which were obtained using activation of mirror neuron. This result suggests that the brain activation occurred by the activation of mirror neuron, which was observed during action observation. The mirror neurons are located in primary motor area, somatosensory area, premotor area, supplemental motor area and somatosensory association area. In sum, when we plan a training program through physiotherapy to increase the effect during reeducation of movement, the action observation as well as best resting is necessary in increasing the effect of motor learning with the patients who cannot be engaged in actual practice.

  • 본 논문에서는 다수 로봇의 목표물 탐색을 위한 area-based Q-learning 알고리즘에 대해 논한다. 선험적 정보가 없는 공간내의 목표물을 탐색하기 위해, 로봇들은 주위의 환경을 인식하고 스스로 다음 행동에 대한 결정을 내릴 수 있어야 한다. Area-based Q-learning에서, 먼저 각 로봇은 정육각형을 이루도록 배치된 6개의 적외선 센서를 통해 자신과 주변 환경 사이의 거리를 구한다. 다음으로 이 거리데이터들로부터 6방향의 면적(area)을 계산하여, 보다 넓은 행동반경을 보장해주는 영역으로 이동(action)한다. 이동 후 다시 6방향의 면적을 계산, 이전 상태에서의 이동에 대한 Q-value를 업데이트 한다. 본 논문의 실험에서는 5대의 로봇을 이용하여 선험적 지식이 없고, 장애물이 놓여 있는 공간에서의 목표물 탐색을 시도하였다. 결론에서는 3개의 제어 알고리즘-랜덤 탐색, area-based action making (ABAM), hexagonal area-based Q-learning - 을 이용하여 목표물 탐색을 시도한 결과를 보인다.

  • The purpose of this study was to examine the learning competencies of students at a college from September 1 to November 30, 2017, in an effort to provide some information on how to foster learning competencies in college years, which lay the foundation for work and social lives. 1. The learning competencies of the subjects consisted of academic vision, student identity, cognitive regulation, emotional regulation, learning management and creating learning environments. Out of five points, they scored the highest in academic vision and student identity with 3.34, followed by learning management with 3.20, creating learning environments with 3.18, emotional regulation with 3.16 and cognitive regulation with 3.14. 2. There were statistically significant differences in academic vision according to age, the area of major, the academic credential of their fathers, commuting time, military service experience and career plans. 3. There were statistically significant differences in student identity and cognitive regulation according to gender, age, the area of major, the academic credential of their fathers, commuting time, military service experience and career plans. 4. There were statistically significant differences in emotional regulation according to age, the area of major, the academic credential of their fathers, commuting time, career plans and daily mean study hours. 5. There were statistically significant differences in learning management according to gender, age, the area of major, grade point average, the academic credential of their fathers, career plans and daily mean study hours. 6. There were statistically significant differences in creating learning environments according to gender, age, the area of major, the academic credential of fathers, commuting time, career plans and daily mean study hours. As they were poorest at the cognitive regulation area among the areas of learning competencies, self-directed learning programs that deal with how to study, learning process, how to take notes and arrange them, how to link different pieces of acquired knowledge and how to map out study plans should be developed to give support to students.

  • 학생의 학습기회를 형성하는 데 있어 교과서는 상당히 중요한 역할을 한다. 이를 고려하면 교과서 분석은 학생들에게 어떠한 학습 기회를 제공하는지 이해하는데 있어 중요하다. 본 연구는 초등학교 수학교과서를 학습 경로(learning trajectory)에 제시된 넓이와 부피 개념의 이해의 발달 단계에 비추어 분석하였다. 1~6학년의 수학교과서 속의 넓이와 부피에 관한 과제들을 그 과제를 해결하는데 요구되는 사고와 행동을 기초로 학습 경로에 제안 된 발달 단계를 이용하여 코딩하였다. 그 결과, 수학교과서 속의 과제와 학습 경로 간의 상당한 불일치를 발견하였다. 우선, 교과서는 학습 경로에 제안 된 나이보다 상당히 늦게 해당 학습 기회를 제공하였다. 또한, 넓이의 경우 5학년, 부피의 경우 6학년에 학습 기회가 집중되어 있었으며, 이런 집중된 학습 기회도 개념의 발달보다는 넓이 또는 부피의 공식을 적용하는데 중점을 두었다. 본 연구의 결과는 교과서 개발뿐만 아니라 수학수업에서 학생의 학습 기회를 확장시키는데 중요한 시사점을 제시한다.

  • 사다리꼴의 넓이는 수학적 사고와 역량을 기를 수 있는 중요한 개념이지만 다수의 학생은 사다리꼴의 넓이 공식을 도구적으로 이해하는 경향이 있다. 이러한 문제를 해결하는 실마리를 Dienes의 수학학습이론과 Watson과 Mason의 예 공간 개념에서 찾을 수 있었다. 본 연구는 사다리꼴의 넓이 교수학습에 관한 시사점을 얻고자 Dienes의 수학학습이론에 따른 사다리꼴의 넓이 학습에서 학생들이 구성한 예 공간을 분석하였다. 분석 결과, 학생들이 구성한 수학학습단계별 예 공간은 놀이 단계의 사다리꼴 변형에 대한 예 공간, 비교·표현 단계의 공통점 표현에 대한 예 공간, 기호화·형식화 단계의 사다리꼴 넓이 식에 대한 예 공간이었다. 단계별 예 공간을 구성하는 예의 종류, 생성, 비중, 관련성을 분석하고 예 공간의 구조를 맵으로 도식화하였다. 단계별 예 공간의 일반적인 예, 특수한 예, 관례적인 예를 분석하고 실제 사다리꼴의 넓이 교수학습실행에서 예와 예 공간을 활용하는 방안을 논의하였다. Dienes의 수학학습이론에 따른 사다리꼴의 넓이 학습수행의 유의미함을 논의하였고 본 연구의 내용은 사다리꼴의 넓이 학습의 한 모델이 될 수 있다.
