Creative thinking appears even before it is expressed in language, and its existence is revealed through emotion, intuition, image and body feeling before logic or linguistics rules work. In this study, Lego is intended to present experimental child interactive content that is applied with a computer vision based on image processing techniques. In the case of infants, the main purpose of this content is the development of hand muscles and the ability to implement imagination. The purpose of the analysis algorithm of the OpenCV library and the image processing using the 'VVVV' that is implemented as a 'Node' in the midst of perceptual changes in image processing technology that are representative of object recognition, and the objective is to use a webcam to film, recognize, derive results that match the analysis and produce interactive content that is completed by the user participating. Research shows what Lego children have made, and children can create things themselves and develop creativity. Furthermore, we expect to be able to infer a diverse and individualistic person's thinking based on more data.

The purpose of this study is to categorize preconceived notions by elementary science gifted students about the reason why only one side of the moon is visible and develop an instructional module to correct these notions scientifically. The effectiveness of these modules will then be tested. The participants of this study were 15 (5th and 6th grade students) from Gwangju Metropolitan City and Chonnam Province who passed a gifted student assessment test developed by J university. The student's notions about the reason only one side of the moon is visible were assessed through questionnaires, interviews, and reenactments. Instructional modules to minimize these notions were developed and then improved upon by class reenactments. And then these modules were used to teach a real class with cameras recording the students. Protocols were analyzed using this footage, and emphasis was placed on how the developed class module changed student's misconceptions. The instructional module developed in this study was: student conception assessment writing materials exploration activity stage 1 (moon's orbit) exploration activity stage 2 (moon's rotation) - exploration activity stage 3 (moon's orbit and rotation) - exploration activity stage 4 (verbalizing the moon's orbit and rotation) - exploration activity stage 5 (thinking about moon movement considering earth's rotation - exploration activity stage 6 (relating the earth and moon's movement) and verifying student conception change. An important conclusion of this study was that all 15 students had misconceptions that could be divided into categories A, B, and C. Category A could be separated with more specifics into A-1 and A-2, and C into C-1 and C-2. After the instructional module was utilized, the student categories show positive change in the following stages: Category A at exploration activity stage 1 and 2, Category B at exploration activity stage 3, Category C-1 at exploration activity stage 4 and 5, and Category C-2 at exploration activity stage 6. Category C-1 students immediately changed to Category C-2 after going through a few stages, and their misconceptions were finally corrected after going through exploration activity stage 6. The misconceptions of students in all categories were corrected scientifically after completing stage 6 education. This study proposes that a combined education of reenactments, exploration materials development, and exploration activities by stages will effectively correct misconceptions about the Earth and moon's movement.

MotionTypography is crucial to effective emotional communication in digital society. In this paper, I study movements to represent emotion using motiontypography and approach two goals: First to define an emotional measure by means of emotion assesses by the public, Second to research image characteristics corresponding to movements. In this dissertation, we collect emotional words by literature and experimental surveys and extract representative emotional words using KJ method and clustering analysis. The results of research, the emotional axes selected for motiontypography represent 'calm to active' and 'soft to stiff', the viewers feel a specific emotional state from some movements of motiontypography. If, we investigate the relationship of motiontypographic visual elements with emotional words are achieved together, I think it will serve as a motiontypographic guideline that enables helping the public to easily produce motiontypography.

The purpose of this study is to observe the cultural phenomenon in modern society from the point of view of pastiche, analyze the characteristics of pastiche, create a framework for studying modem fashion and body ornamentation, one of the facts of cultural phenomenon and, based on these aspects, will observe the pastiche phase, which occurred in body ornamentation of modem fashion in the late 1990's Collections. The characteristics of pastiche is that it transcends meaning, alters the usage of objects, raises the beauty of alienation and pursues temporariness. Observing pastiche, according to its definition and characteristics, as it appears in body ornamentation of modem fashion, the results were as follows: First of all, in terms of transcending meaning, body ornamentation of modern fashion is a mixture of all past styles. Secondly, use of objects in body ornamentation of fashion has shown the use of things which have never been used in accessorizing before, such as birdcages, bones of body, castle. Third, in terms of the raising of the beauty of alienation, accessories from countries, which were not high interest groups in the past, such as piercing, scar, corpulent, are being used as high-fashion accessories in body ornamentation of modern fashion. Fourth, in terms of the pursuit of temporariness, external ornamentation in body ornamentation of modern fashion is seen as permanent changes to the outer body, such as tattoos, piercings, hair color and the more temporary changes, such as coloring.

Clothing color for animation characters is very important in expressing a given characters image and characteristics. Consequently, in this paper, we propose a tool that allows an easy and simple selection of clothing color combinations in conjunction with previous color combination image research (color image chart). This tool has two functions, The first allows the user to search what color best fits a given image, and the second calculates which image is closest to the color that user has chosen. This tool was developed so it can be used over the web, and was used to verify whether the color combination for Disney and Dream Works animated characters' clothing has been selected appropriately according to the character's image, as determined through a survey.

processors must be allocated to incoming tasks in a way that will maximize the processor utilization and minimize the system fragmentation. Thus, an efficient method of allocating processors in a hypercube is a key to system performance. In order to achieve this goal, it is necessary to detect the availability of a subcube of required size and merge the released small cubes to form a larger ones. This paper presents the tree-exchange algorithm which detemines the levels and partners of the binary tree representation of a hypercube, and an efficient allocation strategy using the algorithm. The complexity for search time of the algorithm is $O\ulcorner$n/2$\lrcorner$$\times$2n)and it shows good performance in comparison with other strategies.

본 논문에서는 영상의 중요한 특징을 강조하는 점의 분포를 가지는 자동화된 점묘화(stippling) 제작 방법을 제시한다. 예술가의 점묘화 일러스트 작품을 살펴보면 영상의 특징을 강조하는 방향성이 있는 점들을 사용해서 회화적인 느낌을 살림과 동시에 사물의 형태를 좀 더 명백히 파악할 수 있게 해준다. 하지만 컴퓨터 그래픽스 분야에서 연구된 기존 점묘화 기법 알고리즘은 입력 영상의 특징적인 형태를 고려하지 않고 색조에 따른 점의 밀도 변화만으로 사물을 표현하기 때문에 사물의 형태가 제대로 드러나지 않는 단점이 있다. 본 방법에서는 점의 분포가 대상의 형태를 반영하며 분포되게 하는 알고리즘을 적용하여 사물의 특징적인 형태를 강조한다. 이를 위해 영상의 특징선으로부터 추출한 특징 흐름(feature flow)을 따라 점을 배치시키는 방법을 사용한다. 그리고 입력 영상의 색조(tone)를 점묘화에 반영하기 위해 점의 크기가 입력 영상의 색조에 따라 자동으로 결정되도록 한다.

This paper presents a method for analyzing Hangul glyphs with their outline fonts and obtaining intermediate fonts with two different fonts. The glyphs are represented and analyzed hierarchically such as characters, components(letters) and strokes. With the analysis results, we obtain several intermediate glyphs by morphing two different glyphs of same character. For a natural glyph contour morphing, we employ the curve morphing algorithm by weighted mean of strings. In addition, we provide four operations for transformation of glyphs with different topology. As a result, it is illustrated that the proposed Hangul glyphs morphing scheme is useful for new font generation from any exist fonts or handwritings.
