This study aims at the observation of some analytical levels-especially those of syntactico-semantical- of the visual expressions in general. As far as the syntactical parts are concerned, there were two steps to be approached. One is to select the paradigms according to the Saussure-Hambidgean suggestions, the other to derive syntagmas from what is called the 'chaos-system', one of nonlinear dynamics. In result, paradigms could be acquired 5 sorts with its so many varieties, as visual templates(VT), supplemented by their reciprocals(R) and complements(CLE), and syntagmas five orbits from each constant c=0 to c=10. In additional, in connection with semantic parts, the study introduced a Gremasian model of discourses and narratives for the interpretation of signifiers. By this, we could cover the conjunctive relationships(+) and the disjunctive(-) of the whole structure of visual expression. Finally, we certified that the above could be fully approved in terms of recent worldly cognitive scientic psychological discoveries.

Visual communication is widely used and enhanced in modern society, where there is an increasing demand for spirituality. Museum robots are one of many service robots that can replace humans to provide services such as display, interpretation and dialogue. For the improvement of museum guide robots, the paper proposes a human-robot interaction system based on visual communication skills. The system is based on a deep neural mesh structure and utilizes theoretical analysis of computer vision to introduce a Tiny+CBAM mesh structure in the gesture recognition component. This combines basic gestures and gesture states to design and evaluate gesture actions. The test results indicated that the improved Tiny+CBAM mesh structure could enhance the mean average precision value by 13.56% while maintaining a loss of less than 3 frames per second during static basic gesture recognition. After testing the system's dynamic gesture performance, it was found to be over 95% accurate for all items except double click. Additionally, it was 100% accurate for the action displayed on the current page.

This study aimed to investigate the high school students' conceptions about the plate tectonics through visual representation. For this purpose, the subjects were 67 students in 11th-grade high schools in Chungbuk. In order to in-depth understand the students' conceptions about plate tectonics, so the investigator conducted a semi-structured interview. The conclusions were as in the following. After learning the plate tectonics, the students had the alternative conceptions associated with terminology, colors' meanings, plate-related melting, plate's movement, plates' boundaries, mantle's physical conditions, driving forces for plate movement, and they had the organic relations about colors' meanings, mantle's physical conditions, and driving forces of plate movement. Also, the visual representation used to teach plate tectonics influenced on the students' responses about terminology, plates' boundaries, plate-related melting and the mantle's physical features, also this study found the factors of visual representation causing the learners to create alternative conceptions. These results implicated the importance of teacher's role in identifying the students' interpretation process on visual representation, and it needed to improve the factors creating students' alternative conceptions about visual representation and to study the factors further.

MR acoustic sound or noise due to gradient pulsings has been one of the problems in MRI, both in patient scanning as well as in many areas of psychiatric and neuroscience research, such as brain fMRI. Especially in brain fMRI, sound noise is one of the serious noise sources which obscures the small signals obtainable from the subtle changes occurring in oxygenation status in the cortex and blood capillaries. Therefore, we have studied the effects of acoustic or sound noise arising in fMR imaging of the auditory, motor and visual cortices. The results show that the acoustical noise effects on motor and visual responses are opposite. That is, for the motor activity, it shows an increased total motor activation while for the visual stimulation, corresponding (visual) cortical activity has diminished substantially when the subject is exposed to a loud acoustic sound. Although the current observations are preliminary and require more experimental confirmation, it appears that the observed acoustic-noise effects on brain unctions, such as in the motor and visual cortices, are new observations and could have significant consequences in data observation and interpretation in future fMRI studies.

Extracting primitives from imagery plays an important task in visual information processing since the primitives provide useful information about characteristics of the objects and patterns. The human visual system utilizes features without difficulty for image interpretation, scene analysis and object recognition. However, to extract and to analyze feature are difficult processing. The ultimate goal of digital image processing is to extract information and reconstruct objects automatically. The objective of this study is to develop robust method to achieve the goal of the image processing. In this study, an adaptive strategy was developed by implementing Gabor filters in order to extract feature information and to segment images. The Gabor filters are conceived as hypothetical structures of the retinal receptive fields in human vision system. Therefore, to develop a method which resembles the performance of human visual perception is possible using the Gabor filters. A method to compute appropriate parameters of the Gabor filters without human visual inspection is proposed. The entire framework is based on the theory of human visual perception. Digital images were used to evaluate the performance of the proposed strategy. The results show that the proposed adaptive approach improves performance of the Gabor filters for feature extraction and segmentation.

예술의 이해에 가장 본질적인 태도를 제시했던 이들 가운데 예술학의 제창자인 데스와(Max Dessoir)는 일찍이 "예술이라는 위대한 사실이 함의하는 것들을 모든 방향에서 정당하게 다루어야 할 필요가 있다"고 하면서, 예술이 "인간의 인식활동과 의지활동" 모두에서 기여하기를 희망하였다. 그의 이와 같은 진술에 의거해 보자면, 예술을 사회 역사적으로 해석하되 그것이 인식론적으로 그리고 존재론적으로 타당성을 지닌 것이어야 한다는 것이다. 이러한 정위하여 두 관점이 공존하면서 사회 역사적 해석의 방법을 모색하는데 이 글의 목적이 있다. 이와 같은 목적으로부터 이해의 문제를 주된 연구 범위로 하는 해석학에 대한 고찰은 당연한 절차가 되는데, 이는 해석학이 고대 신탁에 대한 해명으로부터 성서 해석 및 현대의 복잡하고 다의적인 텍스트로서의 예술에 이르기까지 그 본직적인 의미뿐 아니라 존재의 이해를 시도하는 것을 본연의 과제로 삼는 까닭이다. 해석은 그것의 규준을 발견하려는 방법적인 기술학(記述學)을 발전시켜 왔으나, 현대적인 의미에서 해석학은 그러한 방법적 발전보다는 인간 존재의 이해로 전환되어 가고 있다. 이에 대해 리쾨르(Paul Ricoeur)는 해석학이 '인식론'에서 '존재론'으로의 이해했다고 주장하였다. 그러나 해석 대상과 저자의 의도에 보다 충실해온 인식론적 관점과 해석 대상과 해석 주체와의 지평 융합에 의한 존재론적 관점은 우열을 가릴 수 없는 것임에도 불구하고, 두 관점은 각각 독립적인 성격만을 부각되어 배타적인 관계로 간주되어왔다. 이로부터 이 글은 두 관점의 상격만이 부각되어 배타적인 관계로 간주되어 왔다. 이로부터 이 글은 두 관점의 상호 의존적인 관계를 조명함으로써 이것에 의해 해석이 보다 충실해질 수 있음을 주장한다. 이와 같은 의도로부터 두 관점 모두를 상호 의존적인 해석의 절차로 수용하려는 방법적인 개념으로, '귀속'과 '순환'을 제기하였다. 이 두 개념은 해석의 과정에서 그 대상과 그로부터 발생하는 인간 이해의 문제를 밝히는데 상호 의존적이고 상호 보완적으로 작용하여 사회 역사적 해석에 도달하게 하는 구체적 전략이 되기 때문이다.

The MODerate Resolution Imaging Spectroradiometer (MODIS) sensor has 36 bands at 250m, 500m, 1km spatial resolution. However, 500m or 1km MODIS data exhibits a few limitations when low resolution data is applied at small areas that possess complex land cover types. In this study, we produce seven 250m spectral bands by fusing two MODIS 250m bands into five 500m bands. In order to recommend the best fusion method by which one acquires MODIS data, we compare seven fusion methods including the Brovey transform, principle components algorithm (PCA) fusion method, the Gram-Schmidt fusion method, the least mean and variance matching method, the least square fusion method, the discrete wavelet fusion method, and the wavelet-PCA fusion method. Results of the above fusion methods are compared using various evaluation indicators such as correlation, relative difference of mean, relative variation, deviation index, peak signal-to-noise ratio index and universal image quality index, as well as visual interpretation method. Among various fusion methods, the local mean and variance matching method provides the best fusion result for the visual interpretation and the evaluation indicators. The fusion algorithm of 250m MODIS data may be used to effectively improve the accuracy of various MODIS land products.

과학자들은 연구 과정에서 다양한 시각적 표상을 다양한 방식으로 활용한다. 과학 교수 학습 과정에서도 시각적 표상은 과학 개념을 가르치거나 이해하기 위한 수단으로, 또 학생의 과학적 사고를 촉진하고, 탐구 능력을 증진시키기 위한 도구로 활용될 수 있다. 본 연구에서는 과학 교수 학습 과정에서 효과적인 시각적 표상 활용을 촉진하고, 체계적인 과학교육 연구의 기초를 제공하고자 하는 목적으로 시각적 표상능력의 교육목표 분류체계(visual representation competence taxonomy: VRC-T)를 개발하였다. VRC-T는 시각적 표상 유형과 인지 과정, 2개 차원으로 구성하였고, 선행 연구를 고찰하여 초기 모형을 개발한 뒤 교사 중심의 타당도 검토 결과, 전문가 중심의 타당도 검토 결과를 반영하여 최종 모형을 개발하였다. 최종 모형에서 시각적 표상 유형은 크게 '기술적 표상', '과정적 표상', '설명적 표상'으로 구분하였으며, 시각적 표상의 인지 과정은 크게 '해석하기', '통합하기', '구성하기'로 구분하였다. VRC-T의 타당화 과정과 각 세부 범주의 개요 및 예시를 설명하였고 가능한 활용 방안을 제안하였다.

The primary purpose of this research is to scientifically investigate visual structure of Korean feng-shui at the level of village settlement. This study deals with Hahoi and Yangdong villages of which feng-shui is regarded highly fit to traditional feng-shui principles. Methodologically this research utilizes analytical tools of geographical information systems and statistical analysis methods, Visual structures of the villages'feng-shui are analyzed in terms of elevation, orientation, gradient of slope and relative dominance of visibility of major hills. A mathematical model is suggested to quantify facets of the villages'lung-shui with reference to slope trends. The quantitative analysis results indicate that both villages have good feng-shui. Hahoi village has an excellent feng-shui attributable to a near perfect harmony between water and terrain while Yangdong village has an effective feng-shui facet for conserving energy in terms of microclimate. Principles of fang-shui have potentials to be developed as a holistic planning and design language. Further in-depth research on feng-shui needed to accomplish this goal.
