Recently, the occurrence and death rates of cancer have increased rapidly. In oriental medicine, the tongue gives some kind of special physiological information on human body. Oriental medical doctors have used information about the color, degree of wetness and shape of the patient's tongue to determine patient's disease and body condition. This fact leads us that the tongue image is one of the most important clinical data for helping doctor's decision making. It also has significant meaning to cancer patients related with traditional theory of oriental medicine. In diagnosis and treatment of cancer, tongue diagnosis can give some prognosis and change o cancer. It also detect the sign of early stage cancer, but it cannot diagnose the kind of cancer and/or benign or malignant. Nowadays BioTechnology(BT) has developed rapidly, but there are a lot of limits(economy, accuracy, clinical significance, etc). Tongue diagnosis is very economic and practical way of diagnose and has a lot of possibility of development. The need for doctors and it also helps the development of tongue diagnosis related with cancer.

This paper proposes a power efficient 2-dimensional DCT/IDCT architecture driven by input data to be processed. The architecture achieves low power by taking advantage of the typically large fraction of zero and small-valued input processing data in video and image data compression. In particular, it skips multiplication by zero and dynamically activates/deactivates required bit-slices of fine-grain bit partitioned adders within multipliers and accumulators using simple input ANDing and bit-slice MASKing. The processed results from 1-D DCT/IDCT do not have unnecessary sign extension bits (SEBs), which are used for further power reduction in matrix transposer. The results extracted by bit-level transition activity simulations indicate significant power reduction compared to conventional designs.

The recognition of current position and road surrounding of car is very important to driver for safe driving. This paper presents the recognition technique of the road traveling environment using position information hiding and viewpoint transform that monitors the information of road furniture and signature and notifies them to driver. The proposed scheme generates the road images into which the position information are hided, from car camera and GPS module and provides the road information to driver through the viewpoint transformation and the road signature detection. The driving tests with camera and GPS module verified that the position information hiding takes about 66.5ms per frame, the detection rate of road signature is about 95.83%, and the road signature detection takes about 227.45ms per frame. Therefore, we know that the proposed scheme can recognize the road traveling environment on the road video with 15 frame rate.

An intact male, 3-year old, Sapsari, weighing 29 kg with a history of respiratory distress, anorexia, abdominal distension, and depression for 1 day was referred. Radiographic findings included a C-shaped soft tissue mass in the mid-abdominal cavity and loss of serosal detail. Ultrasonographs showed splenomegaly with hypoechoic coarse parenchyma, loss of venous flow in the dilated splenic veins, and thrombi. Based on image findings, acute isolated splenic torsion was diagnosed. Splenectomy and prophylactic gastropexy was performed. Another case was a spayed female, 8-year old, Shih-tzu, weighing 3.7 kg with a history of intermittent abdominal pain and a palpable abdominal mass for 1 year. Radiographic findings showed splenomegaly characterized by a soft tissue round mass. Ultrasonographs revealed displaced splenic hilum and absence of venous flow in the dilated splenic vein. Chronic isolated splenic torsion was diagnosed and also splenectomy and gastropexy was performed. Two dogs were recovered normally after surgery without any complications. Acute form of isolated splenic torsion showed acute systemic clinical signs, severe C-shaped splenomegaly on radiographs, and loss of all of splenic venous flow, perivenous hyperechoic triangle sign, and thrombi on ultrasonographs. Chronic form of isolated splenic torsion showed chronic obscure clinical signs, moderate splenomegaly on radiographs, and partial loss of splenic venous flow on ultrasonographs.

Competition among local governments in a competitive global festival and the festival is going to become the intensify regional strategies as enabled by the improved local image production and has been a symbol of the festival and each municipality is competitive. Is required as a symbol for the symbol can be passed to the consumer in this situation differentiated festive images efficient communication studies on the character. When viewed as a symbolic sign for the character representation of activities for the festival, Can provide a logical framework that is distinct from the idea of a character who relies on intuition and the creative semiotics. In this research paper a semiotic analysis of the character and the character string to enhance communication efficiency concept, Festival effect, we analyzed the correlation of the local culture. Empirical analysis of consumer images, Shared on the basis of empirical results to the consumer means, the paper shows that the influence of each of the other factors is reflected in the character according to the signifier local cultural characteristics and a character region on the concept of a character form culture semiotics interpretation element influences the guidelines of the characters that may be produced.

The purpose of this study is to critically interpret generational trends in contemporary Korea through understanding the consumer experiences of luxury bag purchases of women in their late 20s and early 30s. Previous studies on luxury consumption tend to focus on an analysis of the value of luxury products as a sign and a symbol, the characteristics or class identity of luxury consumers, or expressive behavior in terms of ideal self-image. While including these factors, this study also expands the scope to a reflexive understanding of the social structural context behind the phenomenon of personal consumption. This was achieved by considering consumption in terms of the style and practice of everyday life, as well as its opportunities and limitations. In particular, we pay attention to how luxury bags are reproduced as media, which is a process that is circulated back to consumption, and through this process, this study reflects on capitalist life and subjects.

The present study is a basic research for promoting the globalization of Korean food, aiming to analyze Japanese restaurants in Hong Kong, an international city successful in globalization, focused on their spatial characteristics and food related characteristics and to use the results as basic materials. The results of this study are as follows. As to the characteristics of indoor spaces and food of Japanese restaurants in Hong Kong, first, the locations of Japanese restaurants were mostly easily accessible luxury hotels, office buildings or shopping malls. They displayed Japanese styles well and used conspicuous signs. Their trade names were given after traditional place names, food names, greetings, etc. Second, the spaces of Japanese restaurants expressed contemporary and, at the same time, traditional styles moderately and elegantly by applying emphatic articles such as traditional furniture, tools and folk paintings to contemporary spaces with traditional air, and by doing so, they showed various possibilities. Third, as to the characteristics of food culture, menus were diversified from traditional menus such as kaiseki to everyday menus such as vinegared rice, ramen, skewered roast meat and fusion dish, and at the same time, differentiated by concept. In addition, some restaurants succeeded in globalization and modernization with chains throughout the world. Furthermore, while table setting, food dishing and tableware image were harmonized with the concept of the restaurant space, if tradition needed to be displayed it was used at a minimum, showing the Japanese aesthetic sense through the restaurant space and food. In globalizing Korean restaurants based on the results of this study, we need to link trade name, facade, sign, menu and space with served food, and to plan a consistent story so that Korean culture and images are expressed. In addition, if a manual is made by benchmarking the Japanese government's support policies and relevant businesses' efforts and ideas and provided to Korean restaurants, it will be helpful for Korean restaurants, which spread Korean food culture, to be more competitive and graceful.

A semiotic approach to modem visual arts has emerged since French post-structuralism was introduced to Anglo -American academics by "deconstruction" or "postmodemi sm." It views a work of art as a sign, which is its math odical assumption and, at the same time, makes its appli cation more accessible. In the milieu of modem visual arts' effort to be intimate with general audience, modem art photography is now fared with the request to be a familar and universal domain, instead of being left only in photo books as artistic and academic achievements. More specifically, various photo images puter graphics to such megaexhibitions as "Gwangju Biennale,. "Media City Seo ul," and "Pusan International Art Festival," are main objects of study. A coherent and scientific analysis of visual semitotics is still on the way, however, it is an urgent task how to read and interpret a photo image with multiple meanings. This study argues that visual seniotics can be a powerful tool to enhance the understanding of art photography. After all, seniotics is a product of age； we live in the age of legibility, that is, of reading the work of art well as the social events and phenomena. art well as the social events and phenomena.

Objective : The widely accepted treatment option of a traumatic carotid cavernous fistula (TCCF) has been detachable balloon or coils based fistula occlusion. Recently, covered stent implantation has been proving an excellent results. The purpose of this study is to investigate our experiences with first line choice of covered stent implantation for TCCF at level 1 regional trauma center. Methods : From November 2004 to February 2020, 19 covered stents were used for treatment of 19 TCCF patients. Among them, 15 cases were first line treatment using covered stents. Clinical and angiographic data were retrospectively reviewed. Results : Procedures were technically successful in all 15 cases (100%). Immediate angiographic results after procedure were total occlusion in 12 patients (80%). All patients except two expired patients had image follow-up (mean 15 months). Recurred symptomatic three patients underwent additional treatments and achieved complete occlusion. Mean clinical follow-up duration was 32 months and results were modified Rankin Scale 1-2 in five, 3-4 in five, and 5 in three patients. Conclusion : The covered stent could be considered as fist line treatment option for treating TCCF patients especially in unstable vital sign. Larger samples and expanded follow-up are required to further develop their specifications and indications.

Recently, attention to the pandemic situation represented by COVID-19 emerged problems caused by unexpected shortage of medical personnel. In this paper, we present a method for diagnosing the presence or absence of lesional sign on PA chest X-ray images as computer vision solution to support diagnosis tasks. Method for visual anomaly detection based on feature modeling can be also applied to X-ray images. With extracting feature vectors from PA chest X-ray images and divide to patch unit, region-specific abnormality can be detected. As preliminary experiment, we created simulation data set containing multiple objects and present results of the comparative experiments in this paper. We present method to improve both efficiency and performance of the process through hard masking of patch features to aligned images. By summing up regional specificity and global anomaly detection results, it shows improved performance by 0.069 AUROC compared to previous studies. By aggregating region-specific and global anomaly detection results, it shows improved performance by 0.069 AUROC compared to our last study.
