In this study, the symbols and visual expressions employed in the food culture content of official website designed to promote three cities in Korea, Seoul, Jeonju and Jeju, were subjected to semiotic analysis. In this study, it was assumed that these websites reflected the varying perspectives of the people behind the development and management of these routes of Internet communication, and the semiotic choices made in order to exemplify each city's food cultural image. The aim of the study was to analyze the communication strategies of food cultural branding in the terms of the online content regarding Seoul, Jeonju, and Jeju with a focus on the comparative points in these cities' official websites. This study included conducting semiotic content analyses of the aforementioned cities' official web pages in an attempt to determine the food branding strategies used to differentiation and produce more favorable perceptions of these three cities. Building upon the findings drawn from this comparative study, the present work can be used to determine more effective ways of strategically differentiating the images of local food culture associated with these cities from the view of brand communications. This study also demonstrates viable directions for designing web content for a city where the food cultural messages can be delivered in a thoughtful and effective manner.

This research is implemented to shed new light on the essence of Korean sentiments, aesthetic sense and restructure it in modern ways. In particular, applying the current images of traditional Korean village in Jeonju to neckties is focused on the purpose of globalizing the industrialization of Korean traditional sceneries and Korean image products. Adobe Photoshop CS program was used to develop necktie designs containing the images of the traditional Korean village. To make artworks, the Digital Textile Printing System that is an environment-friendly printing method was used. Moreover, Hanji yarn fabric was adopted for them so as to use Korean materials. The total number of developed designs is eight and neckties for men were made by altering images of the traditional Korean village in modern ways. According to the research results, required are more investment and self-development for proper understandings on our traditional cultural images and their development from now on. Moreover, in my view, customers' desires must be met by comprehending public consciousness, trends and environments to meet customer's desires. Furthermore, higher value-added products must be created by using Hanji yarn and images of traditional Korean villages by distributing high quality designs that will satisfy customers' desires and psychology, producing small quantities of products with various designs and colors.

In this study, the characteristics of the reading materials in elementary school science textbooks developed under the 2009 revised National Science Curriculum were investigated. The criteria for classifying the reading materials were the types of topic, purpose, students' activity, and presentation. The visual images in the reading materials were also analyzed from the viewpoint of type, role, caption type, and proximity type. The results indicated that the number of the reading materials in the 2009 revised science textbooks decreased compared to that of the 2007 revised science textbooks. It was also found that the frequencies of the reading materials expanding concepts of the text and/or requiring corresponding students' inquiry increased. More visual images were used in the reading materials of the 2009 revised science textbooks. However, several limitations were still found to exist; most visual images were illustration and/or picture; many visual images were presented without a caption; there was a problem in the proximity of visual image to text.

The purpose of this study was to develop an effective marketing strategy for socks made of paper mulberry fiber, a new natural fiber, by understanding consumers' concerns and perception about the product and its quality in several dimensions. The first survey determined their perception of the products' image before using it. The second survey gauged consumer satisfaction with product quality after a two-week home-use test. Factor analysis using Cronbach's a and ANOVA analysis were performed for statistical analysis. In conclusion, consumer image perceptions of socks of mulberry fiber were classified into four categories -'practicality', 'wellbeing', 'high-quality' and 'traditionality'. The survey revealed differences between men's and women's perception of the 'practicality' and 'high-quality' factors. The women recognized a mulberry fiber sock as being more practical but of lower quality than did the men. And the quality satisfaction of the product was classified into four factor 'durability', 'suitability, 'wearability' and 'care-easiness'. In the case of 'suitability', men were more satisfied with the product than the women and in 'suitability' and 'wearability', a group of over 40' year-old consumers was more satisfied. The analysis of a relationship between image perception and satisfaction showed that a consumer group that perceived this product to have more 'practicality', 'high-quality' and 'well-being' was also more satisfied with the product. However, the 'traditionality' factor was unrelated to consumer satisfaction.

Although many kinds of stereo matching method have been developed in the field of computer vision and photogrammetry, wrong matches are not easy to avoid. This paper presents a new method to reduce wrong matches after matching, and experimental results are reported. The main idea is to analyze the histogram of the image attribute differences between each pair of image patches matched. Typical image attributes of image patch are the mean and the standard deviation of gray value for each image patch, but there could be other kinds of image attributes. Another idea is to check relative position among potential matches. This paper proposes to use Gaussian blunder filter to detect the suspicious pair of candidate match in relative position among neighboring candidate matches. If the suspicious candidate matches in image attribute difference or relative position are suppressed, then many wrong matches are removed, but minimizing the suppression of good matches. The proposed method is easy to implement, and also has potential to be applied as post processing after image matching for many kinds of matching methods such as area based matching, feature matching, relaxation matching, dynamic programming, and multi-channel image matching. Results show that the proposed method produces fewer wrong matches than before.

This study aims to find out the characteristics of the vegetation landscape characteristics and system which led the formation of the urban image in Jeonju in the late Joseon period connected with urban spatial structure, using designated as treasure No. 1586 which was made in the middle of 18C. The vegetation landscape characteristics of Jeonju in the late Joseon Dynasty derived from the analysis of are summarized as follows. Firstly, the vegetation landscape system in Jeonju is composed of the natural vegetation around mountain area of Jeonju-Buseong, the independent vegetation or cluster planting forests linked with the main facilities, the Bibo-Forests connected with topographical characteristics of Jeonju, and the vegetation combined with a private garden. Secondly, planting landscape was specialized using flag species and local species. Thirdly, the garden-type plantation centered on the back yard or front of main facilities, with the background of natural vegetation landscape combined with the mountain area and the vegetation combined with a private garden, dominates vegetation landscape of Jeonju Buseong as objects. Fourthly, in order to overcome the defects of topographical characteristics, the Bibo-Forests were emphasized as an important planting landscape element in addition to the vegetation landscape elements connected with main facilities. Fifth, ecological vegetation landscape technique was taken considering the topographical characteristics. The characteristics of vegetation landscape of Jeonju Buseong, which is derived from , have an important meaning to restore and reproduce Jeonju's historical features. Especially, the vegetation communities of the non-booming concept combined with the geographical features, the ecological landscape harmonizing with the topography, the round house type landscape mixed with the private house, and the specialization of vegetation landscape using local species are important factors in securing the city image based on the historical characteristics and creating a city brand that utilizes vegetation landscape.

본 논문에서는 그레이레벨 영상을 보다 적은 비트율로 압축하기 위한 효율적인 방법을 소개한다. 제안한 기법의 핵심은 서로 인접한 픽셀을 표현하는 그레이레벨의 쌍에 대한 발생 빈도를 토대로 원래 영상의 그레이레벨 값을 이에 대응하는 등급 값으로 변환시키는데 있다. 등급 값으로 변환된 영상을 데이터의 통계적인 특성이 강화되기 때문에 적은 비트율로 부호화를 할 수 있어 압축 성능을 더욱 향상시킬 수 있다. 비트 깊이가 8인 즉, 8비트의 그레이레벨 영상을 본 논문에서 제안한 기법을 통하여 변환시킨 영상을 기존의 LZW 부호화 및 산술 부호화에 적용시킨 결과, 기존의 부호화 방법보다 향상된 압축 효율을 가져 왔다.

This study reviewed whether radiology-related pictograms listed on the website of hospitals deliver clearly, accurately and quickly the necessary information. TOPSIS was carried out to select the most fitting pictograms for the department of radiology, department of radiation oncology, and department of nuclear medicine. The finally selected pictogram for the department of radiology shows an image of the chest (lungs), while that for the department of radiation oncology shows the process of treatment using equipment. Using these pictograms as standards seem to be appropriate to a certain level. However, the pictogram for department of nuclear medicine has a symbol for a nucleus and is thus inappropriate to meet the standards for a hospital pictogram. This study is meaningful in that it has established evaluation methods and procedures relaetd to radiation pictograms.

The detector performance is important role in acquiring the gamma rays from patients. Among parameters of detector performances, there is density, which relates to respond to gamma rays. Therefore, we confirm the detection efficiency according to various detector materials based on the density parameter using GATE (geant4 application for emission tomography) simulation tool. The NaI (density: 3.67 g/cm³), CZT (Cadimium Zinc Telluride) (density: 5.80 g/cm³), CdTe (Cadmium Telluride) (5.85 g/cm³), and GAGG (Gadoinium Aluminum Gallium Garnet) (density g/cm³) were used as detector materials. In addition, the point source and quadrant bar phantom, which is modeled for 0.5, 1.0, 1.5, and 2.0 mm thicknesses, were modeled to confirm the quatitative analysis using sensitivity (cps/MBq) and the full width at half maximum (FWHM, mm) at the 2.0 mm bar thickness containing visual evaluation. Based on the results, the sensitivity for NaI, CZT, CdTe, and GAGG detector materials were 0.12, 0.15, 0.16, and 0.18 cps/MBq. In addition, the FWHM for quadrant bar phantom in the 2.0 mm bar thickness is 3.72, 3.69, 3.70, and 3.73 mm for NaI, CZT, CdTe, and GAGG materials, respectively. Compared with performance of detector materials according to density, the high density can improve detection efficiency in terms of sensitivity and mean count. Among these detector materials, the GAGG material is efficient for detection of gamma rays.
