To clarify the distribution of joints and fracture zones in the Cheongju granitic mass, we analyzed drill-core and geophysical well-logging data obtained at two boreholes located 30 m from each other. Lithological properties were investigated from the drill-core data and the samples were classified based on the rock mass rating (RMR) and on rock quality designation (RQD). Subsurface discontinuities within soft and hard rocks were examined by geophysical well-logging and cross-hole seismic tomography. The velocity structures constructed from seismic tomography are well correlated with the profile of bedrock depth, previously mapped from a seismic refraction survey. Dynamic elastic moduli, obtained from full waveform sonic and ${\gamma}-{\gamma}$ logging, were interrelated with P-wave velocities to investigate the dynamic properties of the rock mass. Compared with the correlation graph between elastic moduli and velocities for hard rock at borehole BH-1, the correlation points for BH-2 data showed a wide scatter. These scattered points reflect the greater abundance of joints and fractures near borehole BH-2. This interpretation is supported by observations by acoustic televiewer (ATV) and optical televiewer (OTV) image loggings.

Today's world has been changing form post-industrial society to information society, and criteria of human value, also, has been changing from physical to intellectual and sensible. Based on this trend, intellectual and sensible value of a product is becoming more important in comsumer's market than physical value. The environment of product design has been rapidly changing. Users and consumers pursuit sensible satisfaction through their lives based on images of products. As the environment in which a product is used has been more important, companies have placed more emphasis on consumers and users, and are trying to satisfy their consumers by developing products with emphasis on their design, as well as to develop human technology. In ever-changing environment, a question is if sensible design can be developed in product design. Companies could upgrade their competitive power and brand image only if they could develope designs which could satisfy consumers through sensible design approach with a base on systematic research on h~man sensibility. In this context, the purpose of this study was to: investigate consumer's evaluations on and preferences for formative images of products according to the types of human sensibility. This research study placed emphasis on quantitative analysis of consumers' emotional needs to find out consumer's evaluations on and preferences for formative images of products. The researcher reviewed related literature on human sensibility and design, as well as G-Kansei and product design. Data were collected through a questionnaire and analyzed through a statistical program, and highly effective design strategy was investigated through analysis of data and interpretation of the results.

Modern society which human rights and woman's right have been risen is asking for equality treatment of women and men in all sectors of society under sexual equality principle. People say that hidden beneath sexual equality's surface is feminism. Feminism had arisen in the directions that rights and opportunities of women and men are equal. But now, feminism has aimed at woman's right acquisition and realization because men have taken the lead in social activities and political participation historically. This study's purpose is to examine feminism through animation which is image media contents. As everyone knows, media is the glass reflecting the times by reflecting the ideology of the times. In that sense, studying the feministic analysis of research trend in animation which is the representative genre in image media is the meaningful research in understanding the trends of the times. As mentioned above, this study analyzed the and which clearly showed feministic trend. The two animations have the character changes which the objectified women as witch meets the subjective women and the women do a self-directed choice and behavior. Use this to find out the trend of subjective and self-actualizing of Postfeminism in our modern society. Also based on this, this study could predict the changing of feminism arising in the future. This study's limit is that this study is hard to find animation research result related feminism. Symposium related to the feminism animation was held in Korea and there are various interpretation on the internet. This is the next study want even deepening.

Flood monitoring using satellite data has been constrained by obtaining satellite images for flood peak and accurately extracting flooded areas from satellite data. Deep learning is a promising method for satellite image classification, yet the potential of deep learning-based flooded area extraction using SAR data remained uncertain, which has advantages in obtaining data, comparing to optical satellite data. This research explores the performance of SegNet and U-Net on image segmentation by extracting flooded areas in the Khorat basin, Mekong river basin, and Cagayan river basin in Thailand, Laos, and the Philippines from Sentinel-1 A/B satellite data. Results show that Global Accuracy, Mean IoU, and Mean BF Score of SegNet are 0.9847, 0.6016, and 0.6467 respectively, whereas those of U-Net are 0.9937, 0.7022, 0.7125. Visual interpretation shows that the classification accuracy of U-Net is higher than SegNet, but overall processing time of SegNet is around three times faster than that of U-Net. It is anticipated that the results of this research could be used when developing deep learning-based flood monitoring models and presenting fully automated flooded area extraction models.

The acute lumbar pain patients who were unavoidable to take MRI examination were made to take altered lateral recumbent position. they were also not able to control their painfulness and to be in supine position. In this study, it is supposed to increase success rate of the MRI examination through taking the altered lateral recumbent position in using spine and body matrix coil. This altered position made relaxing lumber pain and fatigue for the patients who suffered from sever lumber pain. In these reasons, it decreases the motion artifacts through correcting uncomfortable posture. As a result, qualitative analysis for the image quality was estimated to have average points of supine position A group(lateral recumbent position) of normal candidates and B group(lateral recumbent position) of the abnormal candidates who have sever pain at 4.64, 3.44, and 3.40, respectively. In conclusion, while qualitative analysis in the examination with supine position of the normal patients had significantly high points, the qualitative analysis in the examination with lateral recumbent position of the normal patients and abnormal patients who had sever lumbar pain was almost same. In addition, it was judged that radiologists' imagery interpretation had no other problems in the image evaluation of B group who had acute lumbar pain of abnormal patients. Hereupon, if this technique becomes generalized for the patients who suffer from supine position in the examination, it is supposed to be useful in medical field.

The purpose of this study is to present a theoretical framework for analysis and interpretation of medieval look in fashion by investigating its aesthetic values. Accordingly, it would provide a better understanding of the medieval culture with its composite aspects. Modernism sought to make the Middle Ages in its own image.'New Medievalism' has on the whole tried to avoid reading the Middle Ages onto the modern world. Instead it designates a predisposition about the discipline of medieval studies broadly conceived. Consequently, it has changed the viewpoint of medieval culture from the one-sided angle into the diversified one. As recent studies based on New Medievalism have argued, a close look at the medieval culture revealed the dualistic nature of it, with contradictory aspects such as piety and secularity, ideality and formality coexisting. The characteristics of the medieval culture are categorized to asceticism, naturalism, mysticism and secularism. Asceticism, which is responsible for the melancholic and heavy atmosphere of the medieval culture, is related to christianity and despair of life. It is expressed in medieval dress in forms of body-concealing semi-fitted silhouette, coarse texture and dark color. As a reaction to the extreme splendor and exposure of recent fashion, the ascetic medieval look is attracting attention. The monastic look is characterized by body-concealing silhouettes and minimalized usage of colors and details. Naturalism is the feature seeking for purity of the nature and the human itself. It appears in terms of line as a smooth curve flowing along the body contours, or as a revival style of the Greco-Roman drapery in the medieval dress. Naturalism in the medieval look of the late 20th century fashion is expressed as a pure image with the use of sheer and soft fabric to form a smooth curve flowing along the body contours. Mysticism symbolizes the authority of the Christ and the glory of heaven. It is presented in the medieval dress of the body-concealing straight silhouette made of gorgeous fabrics, brilliant colors and decorations by gems and gold. The insecurity caused by the fin-de-siecle mood is creating a strong interest in religion and it is reflected in fashion as a medieval look reviving the solemn and magnificent style of the medieval dress. Secularism is a reflection of the medieval mind of indulging in the beauty of the mundane world. Heraldry and excessive decorations of the medieval dress are forms of this secularism. These styles of gorgeousness are being refined into a new medieval look of the 1990's. The medieval look of the modern fashion is featured in various styles, reflecting the pluralism of the postmodern society.

The possibility of nanoparticles (NPs) in biotechnology had been discussed by biomedical investigators. Here we report to suggest a solution and problems when using electron microscopy to determine the distribution of quantum dots (QDs) nanoparticles that penetrate skin. The results of this study showed that NPs were able to penetrate stratum corneum (SC) and sebocyte via hair follicle. However, we have found artifacts such as nanoparticles that are produced from combination of free fatty acid and osmium tetroxide during specimen preparation. It is usually difficult to identify NPs. Therefore, we tried to resolve these problems by comparing the cross-correlation image pattern that are derived from the images of sample that had been processed differently. This method can contribute to more accurate interpretation and minimal errors during the analysis using quantum dot as tracer.

Humans process aesthetic functions of objects such as form, size, color, and texture through vision, while at the same time observe them with a symbolic function by a new psychological interpretation based on their past experience. Therefore, it is more important to study and understand the thoughts and psychological influences of how humans perceive with their eyes than what humans simply look with them. With this research purpose in the background, this study will demonstrate in detail the cognitive characteristics of analog and digital images as a symbolic function with a "formative" point of view. Five hypotheses were established, which were proven through the following tests: smartphone, most frequently used in our daily lives, is simplified to a two-dimensional line drawing form, which is set to instances where the R(radius) is applied to the horizontal line of the two-dimensional form of smartphone, where Run-in-R(radius) is applied, and R(radius) rounding is applied to the edges of those shapes. The shapes were combined to form 12 pairs, which was used in a test to the test subjects. As a result, some human characteristics were observed; in specific, some helped prove objectively how humans perceived analog and digital images as psychologically stronger as a symbolic function. If people's thoughts and feelings gained through such study could be stored in database as one value and be provided to product designers, I believe it could be developed into design form as a basic emotional design that consumers desire.

The color appearance of cultural heritage are essential factors for manufacturing technique interpretation, conservation treatment usage, and condition monitoring. Therefore, this study systematically established color reproduction procedures based on the digital color management system for the portrait of Gwon Eungsu. Moreover, various application strategies for recording and conserving the cultural heritage were proposed. Overall color reproduction processes were conducted in the following order: photography condition setting, standard color measurements, digital photography, color correction, and color space creation. Therefore, compared with the color appearance, the digital image applied to a camera maker profile indicated an average color difference of 𝜟10.1. However, the digital reproduction result based on the color management system exhibits an average color difference of 𝜟1.1, which is close to the color appearance. This means that although digital photography conditions are optimized, recording the color appearance is difficult when relying on the correction algorithm developed by the camera maker. Therefore, the digital color reproduction of cultural heritage is required through color correction and color space creation based on the raw digital image, which is a crucial process for documenting the color appearance. Additionally, the recording of color appearance through digital color reproduction is important for condition evaluation, conservation treatment, and restoration of cultural heritage. Furthermore, standard data of imaging analysis are available for discoloration monitoring.
