In the paper. we propose an evaluation model based the adaptive fuzzy systems, which can transform the physical features of a color pattern to the emotional features. The model is motivated by the Soen's psychological experiments, in which he found the physical features such as average hue, saturation, intensity and the dynamic components of the color patterns affects to the emotional features represented by a pair of adjective words having the opposite meanings. Our proposed model consists of two adaptive fuzzy rule-bases and the y-model, a l i r ~ r ys et operator, to fuze the evaluation values produced by them. The model shows con~parablep erformances to the neural network for the approximation of the nonlinear transforms, and it has the advantage to obtain the linbwistic interpretation from the trained results. We believe the evaluated results of a color pattern can be used to the emotion-based color image retrievals.

In this research, the fashion images, which expressed the same theme during the same season in four different fashion collections, were interpreted as emotional characteristics stemming from different factors according to the emotions and images of the regions where the collections were held. The theme, futurism appeared to be hackneyed and oppressive in Paris fashion which emphasized artistic representation of the theme. And futurism appeared to be expressed to be dazzling, unnatural in London fashion which was innovative and avant-garde. And the New York fashion, which accentuated practical, sportive, and elegant styles created active and graceful image about the futurism and the Milan fashion showed the balanced mixture of the three cities' images above. It is interpreted that our domestic fashion consumers think artistic, formative, original, and emotional images as hackneyed and oppressive. On the other hand, they feel comfortable, cheerful, unaffected and graceful about the images that are functional (rather than artistic), sportive, and moderately elegant. And the innovative and avant-garde images like the ones in London collection seem to make people feel unnatural, dazzled, and even depressed. In short, domestic fashion consumers think that the excessive, innovative, original, and formative fashion images appeared I London and Paris are hackneyed and dark rather than artistic, original, or dynamic. On the contrary, the moderate, practical, sportive and elegant New York images and the Milan's which equally showed the three cities' characteristics are regarded as comfortable, elegant, bright, and positive. This result indicates that the fashion market in certain regions seek shared fashion trends and the difference between the regions reflects the different interpretation of fashion themes.

Analysis of a specific wavelength band of a video signal is an old research field. However, studies on the analysis of signals having the characteristics of a specific wavelength band or the generation of samples have been conducted actively in recent years. In this paper, we analyze the signal of digital halftoned image. The interpretation of halftoning in terms of signals was first made by Ulichney. We have come to the view that the signal characteristics between pixels used for half toning are good for blue noise. Lau has developed a halftoning method that uses green-noise characteristics by using output-dependent feedback as an error diffusion method. Jho has developed a method for producing halftoned images using a reaction diffusion model. In this paper, we analyze reaction diffusion halftoning in terms of signal to show green noise and compare it with existing green noise half tone.

Said's Orientalism criticized the European representations on the Middle-East by theorizing orientalism as a discourse. In this text, he explored and criticized the colonial forms of knowledge and language that distorted the image of the colonized. The justification of the discourse of orientalism is derived from the binary system that is originated from Plato which Derrida rejects on the ground that it always privileges one term over the other, that is, colonizer over colonized. Derrida names for this traditional heritage of Western binary system logocentrism which regards logos(the Greek term for speech or reason) as the central principle of language and philosophy, whereas mythos derives its meaning from the logos on the basis of binary oppositions. Thus according to logocentrism, the colonized is merely the defined who can have its meaning from the definers, colonizers. In this paper, utilizing Derrida's a (non)concept called supplement which means both to add on as a surplus and to make up something missing as a mere extra, I propose another alternative interpretation towards the critique of colonial representation by raising internal contradictions in the Platonic dichotomy between logos and mythos embedded in western colonialism discourse, orientalism. I attempt to show that logos(colonizer) and mythos(colonized) is inseparable in itself due to the fact that they exist as supplementary. For this purpose, I demonstrate how colonial binary system constituted and was constituted in terms of language. Through this paper I reinterpret the colonial rationality of privileging 'logos' over 'mythos' by substituting the colonial binary system with the supplement.

Purpose: This study investigated the effects of 1 year of training on imaging diagnosis, using static ultrasonography (US) salivary gland images of Sjögren syndrome patients. Materials and Methods: This study involved 3 inexperienced radiologists with different levels of experience, who received training 1 or 2 days a week under the supervision of experienced radiologists. The training program included collecting patient histories and performing physical and imaging examinations for various maxillofacial diseases. The 3 radiologists (observers A, B, and C) evaluated 400 static US images of salivary glands twice at a 1-year interval. To compare their performance, 2 experienced radiologists evaluated the same images. Diagnostic performance was compared between the 2 evaluations using the area under the receiver operating characteristic curve (AUC). Results: Observer A, who was participating in the training program for the second year, exhibited no significant difference in AUC between the first and second evaluations, with results consistently comparable to those of experienced radiologists. After 1 year of training, observer B showed significantly higher AUCs than before training. The diagnostic performance of observer B reached the level of experienced radiologists for parotid gland assessment, but differed for submandibular gland assessment. For observer C, who did not complete the training, there was no significant difference in the AUC between the first and second evaluations, both of which showed significant differences from those of the experienced radiologists. Conclusion: These preliminary results suggest that the training program effectively helped inexperienced radiologists reach the level of experienced radiologists for US examinations.

Purpose: This study aimed to assess the computer monitors used for analysis and interpretation of digital radiographs within the clinics of the Oral Health Centre of Western Australia. Materials and Methods: In total, 135 computer monitors(3 brands, 6 models) were assessed by analysing the same radiographic image of a combined 13-step aluminium step wedge and the Artinis CDDent 1.0^® (Artinis Medical Systems B.V.^®, Elst, the Netherlands) test object. The number of steps and cylindrical objects observed on each monitor was recorded along with the monitor's make, model, position relative to the researcher's eye level, and proximity to the nearest window. The number of window panels blocked by blinds, the outside weather conditions, and the number of ceiling lights over the surgical suite/cubicle were also recorded. MedCalc^® version 19.2.1 (MedCalc Software Ltd^®, Ostend, Belgium, https://www.medcalc.org; 2020) was used for statistical analyses(Kruskal-Wallis test and stepwise regression analysis). The level of significance was set at P<0.05. Results: Stepwise regression analysis showed that only the monitor brand and proximity of the monitor to a window had a significant impact on the monitor's performance (P<0.05). The Kruskal-Wallis test showed significant differences (P<0.05) in monitor performance for all variables investigated, except for the weather and the clinic in which the monitors were placed. Conclusion: The vast performance variation present between computer monitors implies the need for a review of monitor selection, calibration, and viewing conditions.

Purpose: Direct intraoral scanning and superimposing methods have recently been applied to measure the dimensions of periodontal tissues. The aim of this study was to analyze various correlations between labial gingival thickness and underlying alveolar bone thickness, as well as clinical parameters among 3 tooth types (central incisors, lateral incisors, and canines) using a digital method. Methods: In 20 periodontally healthy subjects, cone-beam computed tomography images and intraoral scanned files were obtained. Measurements of labial alveolar bone and gingival thickness at the central incisors, lateral incisors, and canines were performed at points 0-5 mm from the alveolar crest on the superimposed images. Clinical parameters including the crown width/crown length ratio, keratinized gingival width, gingival scallop, and transparency of the periodontal probe through the gingival sulcus were examined. Results: Gingival thickness at the alveolar crest level was positively correlated with the thickness of the alveolar bone plate (P<0.05). The central incisors revealed a strong correlation between labial alveolar bone thickness at 1 and 2 mm, respectively, inferior to the alveolar crest and the thickness of the gingiva at the alveolar crest line (G0), whereas G0 and labial bone thickness at every level were positively correlated in the lateral incisors and canines. No significant correlations were found between clinical parameters and hard or soft tissue thickness. Conclusions: Gingival thickness at the alveolar crest level revealed a positive correlation with labial alveolar bone thickness, although this correlation at identical depth levels was not significant. Gingival thickness, at or under the alveolar crest level, was not associated with the clinical parameters of the gingival features, such as the crown form, gingival scallop, or keratinized gingival width.

Background: This study was designed to evaluate and compare the diagnostic value of magnetic resonance imaging (MRI) and indirect magnetic resonance arthrography (I-MRA) imaging with those of arthroscopy and each other. Methods: This descriptive-analytical study was conducted in 2020. All patients who tested positive for labrum lesions during that year were included in the study. The patients underwent conservative treatment for 6 weeks. In the event of no response to conservative treatment, MRI and I-MRA imaging were conducted, and the patients underwent arthroscopy to determine their ultimate diagnosis and treatment plan. Imaging results were assessed at a 1-week interval by an experienced musculoskeletal radiologist. Image interpretation results and arthroscopy were recorded in the data collection form. Results: Overall, 35 patients comprised the study. Based on the kappa coefficient, the results indicate that the results of both imaging methods are in agreement with the arthroscopic findings, but the I-MRA consensus rate is higher than that of MRI (0.612±0.157 and 0.749±0.101 vs. 0.449±0.160 and 0.603±0.113). The sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of MRI in detecting labrum tears were 77.77%, 75.00%, 91.30%, 50.00%, and 77.14%, respectively, and those of I-MRA were 88.88%, 75.00%, 92.30%, 66.66%, and 85.71%. Conclusions: Here, I-MRA showed higher diagnostic value than MRI for labral tears. Therefore, it is recommended that I-MRA be used instead of MRI if there is an indication for potential labrum lesions.

Didier Éribon's dialogue with Ernst Gombrich, first published in 1991 in France, stands as a curious example of interpreting a scientific mind into a popular narrative. On the occasion of its brand new translation in Korean, this essay examines the encounter of two different languages, that of scholarly art history and the other, of "entretien". Éribon's previous interviews with Georges Dumézil and Claude Lévi-Strauss have already shown the perfect use of dialogue that interprets in simple words some currents of European thoughts of 20th century at its highest level. The double identity found in the extraordinary profile of the author of The Story of Art should help us deal with this particular form of dialogue in depth, and expect another possibility of explaining and reconstructing academia.

The purpose of this study is to show the works of Jeju artists and ways to contribute to the Jeju tourism industry, with the research background in that it has recently continued to accept the works of Jeju contemporary artists and draws active works. As a measure to achieve this research purpose, the Deep Dream Generator software was judged to be an effective method for promoting this study. As a specific research process, we will use the Deep Dream Generator to synthesize each of the works of Jeju artists and works of famous foreign artists provided by Deep Dream Generators with their own photos of Jeju Oreum and display the results, and attempt to reinterpret Jeju Oreum using artificial intelligence. In addition, it is expected to revitalize Jeju's art works and tourism by seeking ways to use the results in Jeju tourism products.
