In this paper, a study on facial movements are analyzed in terms of opposite emotion stimuli by image processing of Kinect facial image. To induce two opposite emotion pairs such as "Sad - Excitement"and "Contentment - Angry" which are oppositely positioned onto Russell's 2D emotion model, both visual and auditory stimuli are given to subjects. Firstly, 31 main points are chosen among 121 facial feature points of active appearance model obtained from Kinect Face Tracking SDK. Then, pixel changes around 31 main points are analyzed. In here, local minimum shift matching method is used in order to solve a problem of non-linear facial movement. At results, right and left side facial movements were occurred in cases of "Sad" and "Excitement" emotions, respectively. Left side facial movement was comparatively more occurred in case of "Contentment" emotion. In contrast, both left and right side movements were occurred in case of "Angry" emotion.

In this paper, as a liberal arts course for non-majors, we developed a basic practice case for convolutional neural networks, which is essential for designing a basic convolutional neural network course curriculum. The developed practice case focuses on understanding the working principle of the convolutional neural network and uses a spreadsheet to check the entire visualized process. The developed practice case consisted of generating supervised learning method image training data, implementing the input layer, convolution layer (convolutional layer), pooling layer, and output layer sequentially, and testing the performance of the convolutional neural network on new data. By extending the practice cases developed in this paper, the number of images to be recognized can be expanded, or basic practice cases can be made to create a convolutional neural network that increases the compression rate for high-quality images. Therefore, it can be said that the utility of this convolutional neural network basic practice case is high.

Measurement plays an important role in both school mathematics and real life. Among the measurement areas, length is the first to learn and is the basis for measurement. Time is measured in its own way and is characterized by being the most abstract. This study attempted to analyze elementary mathematics textbooks and representations in real life to examine how the length and time of learning in school mathematics differ from those represented in real life. Based on this, we tried to derive implications for the direction of measurement education and elementary math textbooks. As a result of the analysis, the concept of length was used the same in real life and school mathematics. However, terms such as distance, depth, and height were not defined, and the representation of the approximate value was presented in a fragmentary form. In addition, there were parts where students were likely to feel confused in school mathematics and real life, such as the same units such as 'minutes and seconds' were used in time. Therefore, considering these differences, it is necessary to consider the direction of composition of math textbooks and teaching and learning so that students can connect school mathematics and real life and understand widely about measurement concepts.

This article compared and analyzed the SF films Snowpiercer and Space Sweepers, which embody the imagination of disaster for the future dystopian society. In common, the two films represent the future society as a society with a serious climate crisis and an extremely widening gap between the rich and the poor. Both films use similar narrative strategies: representing a isolated, twisted-willed scientist figure, building a main stage as catastrophic hierarchical capitalist society, and focusing on the conflicts between a dominant group possessing the science-capital-power and a resistant but ordinary subjects. However, there is the different framing on the future society in terms of representing nature, science technology, and human-nonhuman agency. This distinction is shaped by the narrative function of the objects represented by two films.

Purpose : The purpose of this study was to examine the effects of applying occupational therapy that uses motion recognition on the physical self-efficacy, visual-motor integration ability, and play skills of children who have neurodevelopmental disorder before and after treatment. Methods : This The study chose 16 children with neurodevelopmental disorder as research subjects who were randomly and evenly allocated into an experimental group and a control group. The experiment followed a pretest-posttest design. As an intervention, the experimental group received motion recognition-based occupational therapy and a separate sensory integration program. The control group only participated in the separate sensory integration program. The eight-week experiment duration included 24 intervention sessions where the a 50-minute session was implemented three times a week for eight weeks. To compare the physical self-efficacy, visual-motor integration ability, and play skills before and after the intervention, measurement tools including the Physical self efficacy, Beery VMI-6, and Penn interactive peer play scale were used. All measured variables were analyzed and expressed as mean, standard deviation and percentage. Results : The motion recognition-based occupational therapy demonstrated a significant effect on improving the physical self-efficacy, visual-motor integration ability, and play skills of the experimental group. The intervention also caused a significant difference between the experimental group and control group in terms of the physical self-efficacy, visual-motor integration ability, and play skills. Conclusion : We confirmed the possibility motion recognition-based occupational therapy could be effective in improving the physical self-efficacy, visual-motor integration ability, and play skills for patients who have neurodevelopmental disorder. Based on the study result, further future studies are expected based on this study result that prove the application effect of the motion recognition-based occupational therapy using disabled and non- disabled children as subjects are expected in the future.

IT companies make a lot of effort to share and utilize the experiences of their members and transform them into organizational knowledge as a competitive core. However they face a dilemma in that they have to spend time and financial resources to perform activities around knowledge management for the long-term gains, while carrying at field-work for making short-term profits. As an initial attempt to tackle this managerial problem, this paper tries to investigate the mechanism of knowledge management in a small IT company in Korea with a synthetic view-point using system dynamics simulation model. It depicts the dynamic behaviors of knowledge management and presents some findings of political leverage. Although this model has to be further replenished, the scheme for the dynamism of knowledge management and the findings presented in the paper could be useful for the decision makers, especially of knowledge-intensive organizations.

Analogical thinking is a problem-solving strategy to use a familiar problem (or base analog) to solve a novel problem of the same type (the target problem). The purpose of this study is to provide new insight into geography teaching and learning by connecting cognitive science research on analogical thinking with issues of geography education and suggest that teaching with analogies can be a productive instructional strategy for geography. In this study, using the various examples of analogical thinking used in geography we defined analogical thinking, addressed the theoretical models on analogical transfer, and discussed conditions that make an effective analogical transfer. The major research findings include the following: a) the spatial analogy, indicating skills to find places that may be far apart but have similar locations, and therefore have other similar conditions and/or connections, can provide a useful way to design contents for place learning; b) representational transfer, specifying a common representation for two problems, can play a key role in solving geographic problems requiring data visualization and spatialization processes; and c) either asking learners to compare/analyze similar examples sharing common structure or providing them examples bridging the gap between concrete, real-life phenomena and the ideas and models can contribute to learning in geographic concepts and skills. The spatial analogy requiring both geographic content knowledge and visual/spatial thinking has the potential to become a content-specific problem-solving strategy. We ended with recommendations for future research on analogy that is important in geography education.

한국근대미술은 유화 도입기인 1910년대를 한국미술사의 중요한 시작점이다. 1910년경부터 형성되기 시작한 유화 도입배경과 그것이 당시 사회의 절실한 요청에 의한 것이었는지, 그렇다면 그것이 무엇인지 규명하는 것이 한국근대미술 초기를 알 수 있는 중요한 문제일 것이다. 일본근대 유화의 역사는 국수주의와 서구주의 물결이 반복하는 과정에서 점차 일본화된 소재의 등장과 일본정서에 부합하는 화풍을 만들어 나가게 되는 것이 1890년대부터 1910때까지의 일본근대 유화계의 상황이라고 할 수 있다. 이 시기를 다시 요약하면 외광파와 인상파가 절충된 양식에 일본의 메이지낭만주의에 부합하는 소재 즉 일본전통이라고 할 수 있는 풍경에 대한 애착 등이 전체 유화의 기류로 나타나는 시기라고 할 수 있다. 실제 새로운 문화의 하나였던 유화는 점차 세계의 다양한 미술사조 속에서 일본화다운 것으로 발전하는 모습을 보여준다. '구로다 세이키'(黑田淸輝) 이전에 이미 형성되었던 일본근대 유화양식과 구로다의 외광파 양식, 또 외광파가 일본 근대유화의 주류로 형성하게 되는 계기, 여기에 프랑스에서 직접 배워 온 작가들에 의한 인상파 도입 그리고 일본 '메이지낭만주의'(明治浪漫主義)의 등장으로 인한 사회 환경구조의 변화 속에서 양성된 그들의 절충양식의 초기유학생들에게 큰 영향을 미쳤다. 우리근대미술은 '민족적 자부심'과 '민족적 열등감'이 동시에 존재하는 사회적 배경논리에서 출발하지 않으면 안 된다. 즉 근대미술의 사상적 배경에는 민족 개량주의적 발상과 계몽주의적 문화 활동에 있었다고 할지라도 근본적으로는 미술자체를 근대사회 발전의 연장선 속에서 파악하지 못했고, 따라서 미술자체를 새로운 문명수입이라는 근대적 풍물 정도로만 파악했던 것이 어쩔 수 없는 근대미술의 한계라고 할 수 있다. 이 시기에 미술을 주목한 이유는 근대적 사회로 발전하기 위한 하나의 필수적인 요소로 미술자체를 파악하고 나아가, 식산흥업(殖産興業)의 수단으로 인식 했던 신지식층에 의해 시작되었다고 할 수 있다. 문명의 발달이 미술의 발달에서 연원한다는 '미술문명론' 같은 시각이 미술자체가 성격이나 창작의 방향과는 무관하게 어떤 미술이든 그것을 활성화시키는 것이 근대 즉 문명화된 세계로 나아갈 수 있다고 하는 관점에서 비롯된 것이라고 할 수 있다. 한국근대미술에 있어서 아카데미즘 역시 일본근대미술과 불가분의 관계가 있음을 부인할 수 없다. 초기유학생들은 그 당시 일본의 잡지나 화단에서 일어나는 여러 가지 시안들을 피상적으로 이해하는 정도였을 것으로 파악할 수 있다. 이러한 맥락에서 보면 한국근대미술에 있어서 초기유학생들의 작품과 그 이후 선전에서 입선하는 작품들은 일본아카데미즘의 영향 밑에 있다고 해야 할 것이다. 일본 근대 유화에서 형성된 외광파의 요소와 인상파 요소들이 일본 낭만주의로 표면화된 하나의 일본근대 유화의 형식 그대로가 한국아카데미즘의 성격을 결정하고 있다고 할 수 있다. 게다가 1922년에 시작된 선전은 심사위원 대부분이 동경미술학교 교수이면서 구로다의 제자이거나 동료였다는 것은 이러한 사실을 더욱 확고하게 뒷받침하고 있는 것이다. 초기유학생들이 남긴 작품들은 완전한 인상파에 대한 지식이나 깊은 자아의식을 가지고 제작된 것은 아니라, 일본 동경미술학교에서 가르치고 있었던 것들을 그대로 수용했다고 할 수 있다. 따라서 이들의 그림은 구로다의 외광파라고 부르는 것들의 영향보다는, 인상파를 보고 배웠던 동경미술학교 교수들의 영향을 더 많이 받았다고 할 수 있다. 그리고 이들의 영향은 그대로 한국 근대미술의 아카데미즘을 형성하는데 커다란 영향을 미치고 있음을 부인할 수 없다.

The light is the language. Directors have to describe the scene component effectively his intention to configure the scene as an appropriately. After this act of the character, the layout of the props and scene lights will enter to the scene components. Those things help to audiences can understand narrative of work and emotion that producer want to send. Expressing their emotions especially using the lights by adjusting the colors and contrast makes audience to concentrate on work and understand naturally. This lighting technique clearly appears on early year theaters stage of England and Rembrandt's paintings. Properly dividing and controlling the lights dramatically increases the beauty of the work elements to express a variety of emotions such as worries and fear. Therefore, it can be evolve depending on director's intent of using lights on his work. Lights can increase involvement of human emotion through basic features that cognition of object, visualization of space-time and by artistic method in the product. This study will examine the role and how to use lighting to express the proper sentiment based on the narrative of the work. Making research named "Lighting Research of 3D animated film which applying light features to express emotion" previous study and have to combine emotional vocabulary and emotion-based theory for classifying the emotional language that can be applied on 3D animation. And choosing most emotional scene from 3D animation for analyze how they used lighting to expressing emotions. Directors trying to show up about the light role through light method that matched perfectly with an emotional language. Expecting this research work of directing 3D animations light for expressing emotional feelings will be continue successfully.

Since ancient times, legends and tales have been handed down with a spirituality, shamanistic meaning, and imagination. Among many tales about people and animal footprints that are handed down in various parts of Korea, Changnyeong's 'Munhojang Footprint' is the first case in which the physical evidence(footprints) that the main character has left was identified as a dinosaur footprint. In this study, we performed a scientific analysis based on the basic data collection, distribution pattern of 'Munhojang Footprint', three-dimensional digital recording and visualization, as well as case analysis and humanitic review of footprints in tales and legends. The Munhojang Footprints has long been known as human footprints left in the natural rock due to its shape and preservation status. A new analysis that the Munhojang footprints (composed of 13 footprints) are dinosaur tracks shows social perceptions of the ancient people, characterized by the fear of supernatural beings and the limits of scientific interpretation. Through this scientific and humanistic exploration of Munhojang Footprint that are passed down from generation to generation as legends, pray for peace and well-being of the village through rituals and rituals every year, and have been preserved and managed as practical evidence, it is expected that traditional culture and natural heritage will be linked and mutual value will be enhanced.
