Today, as individuals show their social identities and reflect their being as the members of society with a culture, an art style and communication function are stood out in fashion photographs. Accordingly, the meanings of images into text are expanded in its interpretative width through the acceptor's various terms. This researcher looked into four theories of both positions on the textuality of language and image, and considered the point of discussion on image of each theory through modern fashion photographs. First, the theory which divides language and image as auditory and visual recognitions in the textuality of language and image is limited from the view it focuses on only one side without considering the ambivalent elements of each field. For the textuality in modern fashion photographs, the observer attempts to turn it into text to give meaning to it as the recognition through five senses conforming to the acceptor's condition. Second, the theory dividing language and image into the text of time properties and spacial properties has limitation in the text, for acceptor's experience of the object appears as the structured form in time and space rather than being defined as two things like time and space. Third, the theory classifying the language and image text into conventional taste and natural taste has limitation from the view that image text is hardly an object of consistent classification in ease of recognition by the code accepted in society. Thus, this can't be fundamental approach for the understanding of the text of decoding trend represented in modern fashion photographs. Fourth, accordingly, this researcher focussed on contextual and arbitrary text of fashion photographs through the theory of Nelson Goodman which discusses image text through the differences in textuality. Basic mechanism of perceiving and recognizing and distinguish image is closely related to habit and custom like language. So, each acceptor perceives the image as a text through arbitrary interpretation obtained by individual, empirical, historical, and educational viewpoints. The textuality of modern fashion photographs aims to widen the range of diverse knowledge and understanding, transcending the regulations of simple function of existing fashion photographs. Consequently, this researcher puts forward the opinion of consistent and diverse follow-up studies on instilling meaning into fashion photographs for the understanding de-regulatory and de-constructive through various senses by avoiding only one sense-dependent fixed and regulatory properties of it.

뉴스의 중요성이 한층 강조되고 있는 정보화시대에 TV뉴스의 영상제작 분야는 다매체 다채널 디지털방식 등 첨단 기술로 끊임없이 진보되어 오고 있다. 하루가 다르게 발전하는 첨단 방송장비들과 새로운 표현기법들은 오랫동안 방송현업에 종사하고 있는 사람들도 당황스럽게 한다. 영상제작방식은 변화의 속도를 더 빠르게 실감하고 있으며 고품질의 영상정보를 수용하려는 시청자들은 이런 변화들을 오히려 반겼을 것이다. 그 동안 전통적 관념으로 영상표현방식이 존재하고 있었는데 TV뉴스 영상에서는 이미지너리 라인을 적용한 표현방식이 있었다. 수용자에게 이제 전통적인 영상표현은 TV뉴스 속에서 중요성을 상실하고 있다. 그러나 진보되어가는 시대적 흐름에 영상표현 방식도 변화를 가져왔고 영상 제작자들은 시청자들의 욕구를 충족시키기 위하여 보완점을 만들어 냈다. 본 논문에서는 기존의 영상제작 방식도 시대적 흐름에 따르지 않고 적응하지 못하고 있다는 의미에서 TV뉴스영상의 이미지너리 라인을 확대 해석해야 할 필요성을 제기하고자 한다. 지금의 영상은 오직 비디오만을 주장하지 않는다. 비디오와 오디오를 통틀어 정의되고 있다. 아울러 이미지너리 라인의 개념도 영상제작에 확대 해석하고 적용해서 수용자들의 이해를 돕고 바른 TV뉴스 영상을 수용자 뿐 아니라 제작자들에게도 인식시키고자 한다.

우표는 그 시대를 읽을 수 있는 가장 작은 이미지 상징물로 발행국의 역사와 문화, 정치 또는 기념이 될 만한 시대적 인물과 사건들이 함축되어 있다. 특히 역대 대통령 기념우표 속에는 한국의 현대사가 녹아 있으며 역사적으로 대통령 우표에 담긴 의미를 재조명하고 고찰하는 것은 정치 지도자의 이미지를 연구하는 연구자로서 간과할 수 없는 의미를 갖는다. 본 연구는 지면 광고와 우표를 통한 정치지도자 홍보 빈도가 높았던 제1공화국에서 제5공화국까지 연구 범위로 하였으며 한국의 역대 대통령 이승만, 박정희, 전두환 취임, 업적 기념우표를 중심으로 지도자 이미지 형성과 변화 과정을 연구하였다. 시대 변화에 따른 정치지도자 이미지 해석을 위해서 오스굿의 '의미변별척도법'을 사용하여 이미지를 분류하였으며, 소쉬르의 '기호학'을 이용하여 이미지를 분석하였다. 이미지는 계속 살아서 움직이고 변화하고 있으며 당대의 정치지도자 이미지가 단순한 개인적인 이미지 구축이 아닌 특정한 그 시대의 시대상을 반영한 사회적 산물이라는 결론을 도출하였다.

Che Guevara spearheading the Cuban Revolution was not only the icon as the revolutionary to the New-leftists of the 1960s advocating the ideology of Marxism but, as the cultural revolutionary, had a tremendous influence on the younger generation living in the digital age Che Guevara take on a figure of both the symbol of the Leftist but the romantic revolutionary because he had the external features such as black beret, red stars, military upper jackets and trousers, beard and pipe tobacco. In fact, the symbolic image of Che Guevara was made as the popular image by the avantgarde artists and political vanguard forces of the times under the necessity of Cuban government. Afterwards, the image of Che Guevara has been patronized in making people of aware of the resistant and revolutionary image to capital, power and the power of the media and symbolized as the resistant image to the American capital as well as the revolutionary guerrilla. And his image has continued to be reproduced and symbolized for the commercial and political purposes and as the enthusiastic image of youth culture. This can be seen as having been created as a new image by the popular culture formed by the development of the cyber culture and mass media in the cyberspace shaped by contemporary 'N' generations. The use of Che Guevara's symbolic image was made in the fashion field as well as in the cultural and artistic circles. The borrowing of the icon of Che Guevara represented in a fashion field is attributed to his free spirit, and it can be seen that fashion exists as the vehicle for representing both the symbol system and the sign system containing ideologies and texts as the communicator of resistance to the regime and to social issues. Therefore, this study attempted to investigate the commercial iconization of Che Guevara in the 1990s by comparing the ideology of the symbol in the 1960s and the 1990s and inquire into the borrowing of his image by the fashion domain as well as the fashion worn by him by reference to domestic books and materials on the fashion site. Thereby, this study attempted to make clear that the borrowing of Che Guevara in the realm of fashion since the 1990s not only contained the meaningful interpretation as the symbolic code in the culture of young people living in a digital era but fashion performs an intervening role in the cultural phenomenon.

Objective : Obtaining real-time image is essential for neurosurgeons to minimize invasion of normal brain tissue and to prompt diagnosis of intracranial event. The aim of this study was to report our three-year experience with a mobile computed tomography (mCT) for intraoperative and bedside scanning. Methods : A total of 357 mCT (297 patients) scans from January 2009 to December 2011 in single institution were reviewed. After excluding postoperative routine follow-up, 202 mCT were included for analysis. Their medical records such as diagnosis, clinical application, impact on decision making, times, image quality and radiologic findings were assessed. Results : Two-hundred-two mCT scans were performed in the operation room (n=192, 95%) or intensive care unit (ICU) (n=10, 5%). Regarding intraoperative images, extent of resection of tumor (n=55, 27.2%), degree of hematoma removal (n=42, 20.8%), confirmation of catheter placement (n=91, 45.0%) and monitoring unexpected complications (n=4, 2.0%) were evaluated. A total of 14 additional procedures were introduced after confirmation of residual tumor (n=7, 50%), hematoma (n=2, 14.3%), malpositioned catheter (n=3, 21.4%) and newly developed intracranial events (n=2, 14.3%). Every image was obtained within 15 minutes and image quality was sufficient for interpretation. Conclusion : mCT is feasible for prompt intraoperative and ICU monitoring with enhanced diagnostic certainty, safety and efficiency.

Worldview-3 satellite sensor provides panchromatic image with high-spatial resolution and 8-band multispectral images. Therefore, an image-sharpening technique, which sharpens the spatial resolution of multispectral images by using high-spatial resolution panchromatic images, is essential for various applications of Worldview-3 images based on image interpretation and processing. The existing pansharpening algorithms tend to tradeoff between spectral distortion and spatial enhancement. In this study, we applied six pansharpening algorithms to Worldview-3 satellite imagery and assessed the quality of pansharpened images qualitatively and quantitatively. We also analyzed the effects of time lag for each multispectral band during the pansharpening process. Quantitative assessment of pansharpened images was performed by comparing ERGAS (Erreur Relative Globale Adimensionnelle de Synthèse), SAM (Spectral Angle Mapper), Q-index and sCC (spatial Correlation Coefficient) based on real data set. In experiment, quantitative results obtained by MRA (Multi-Resolution Analysis)-based algorithm were better than those by the CS (Component Substitution)-based algorithm. Nevertheless, qualitative quality of spectral information was similar to each other. In addition, images obtained by the CS-based algorithm and by division of two multispectral sensors were shaper in terms of spatial quality than those obtained by the other pansharpening algorithm. Therefore, there is a need to determine a pansharpening method for Worldview-3 images for application to remote sensing data, such as spectral and spatial information-based applications.

Background: Computed tomography urography (CTU), based on the excretion of contrast medium after its injection, allows visualization of the renal parenchyma and the renal collecting system. Objectives: To determine the optimal contrast medium dose allocation ratio to apply in split-bolus CTU in dogs. Methods: This prospective, experimental, exploratory study used 8 beagles. In 3-phase CTU, unenhanced-, nephrographic-, and excretory-phase images were obtained with a single injection of 600 mg iodine/kg iohexol. In split-bolus CTU, two different contrast medium allocation ratios (30% and 70% for split CTU 1; 50% and 50% for split CTU 2) were used. Unenhanced phase image and a synchronous nephrographic-excretory phase image were acquired. Results: Although the attenuation of the renal parenchyma was significantly lower when using both split CTUs than the 3-phase CTU, based on qualitative evaluation, the visualization score of the renal parenchyma of split CTU 1 was as high as that of the 3-phase CTU, whereas the split CTU 2 score was significantly lower than those of the two others. Artifacts were not apparent, regardless of CTU protocol. The diameter and opacification of the ureter in both split CTUs were not significantly different from those using 3-phase CTU. Conclusions: Split-bolus CTU with a contrast medium allocation ratio of 30% and 70% is feasible for evaluating the urinary system and allows sufficient enhancement of the renal parenchyma and appropriate distention and opacification of the ureter, with similar image quality to 3-phase CTU in healthy dogs. Split-bolus CTU has the advantages of reducing radiation exposure and the number of CT images needed for interpretation.
