This study is intended to understand an implication system and significance in the current community which a body image symbolizes by correlating it with fashion that is on the rise as a principal issue in various fields. For this study, the symbolism of the body image was contemplated in terms of philosophy and art, and then on the basis of it, the symbolism of the body image shown in modern fashion design was analyzed through fashion works. The research results are as follows, 1. The manifestation of sex can be taken as the symbolism of the body image which is expressed in modern fashion design. Recently sexual chaos and vagueness such as homosexuality and bisexuality are expressed through a dress and its ornaments. Though displaying sexual characteristics of male and female as they are exposing a sign or a diagram, decorating a part of body or representing sex in garments, uncertain sex identity in modern society is manifested in dress and its ornaments. It is to deny absoluteness regarding sex and emphasize diversity indwelt in human beings, and after all it shows to pursue the human essence. 2. Another symbolism of the body image is body expression as the human race and an ethnic group. The discriminating situations and the restoration of their status appeared in modern fashion too. Moreover, their cultures and issues came to alter the aesthetic standard of body made from a view of the Western white supremacist. Hereupon, fashion trends like ethnic fashion, Orientalism and African look etc. appear according to this tendency, which represents race and national identity and in addition, which signifies to present transcendental human conception embracing alienated human conception. 3. The symbolism of the body image expressed in a body, and a dress and its ornaments as nature can be considered in terms of the concern on environmental contamination and the respect of echo system. Getting away from reigning over, developing and stamping down nature at their will, the human beings pursue unity with nature, which is described in fashion. They are stressing that natural materials and objects such as animal, plant and soil etc. should activily be introduced into fashion and humans are a communal fate group and should reframe their status in nature at last. 4. The body image shown in a body, a dress and its ornaments as technology is transformed and recreated by modern scientific techniques and medical science to show post human conception namely, forthcoming future human conception as a cyborg which loses individual identity. This presents a perfect future human conception with high level of preternatural power but after all, leaves us a task to seek the meaning of human existence in alienation caused by the loss of human identity and existence. In this manner, the moderns crave for perceiving the identity of a natural human being in the current thoughts tendency of the modern times such as postmodernism, post structuralism, deconstructionism, feminism and so on, which build discussions affecting the art and fashion worlds. The categories, like sexual characteristics indwelt in a human body, racial classifications, the natural environment surrounding human beings and development of science, bring out the importance of the internal and external meaning in today's fashion which a human body contains, and present sew human conception in the coming future society.

In order to obtain satellite image products using the image transmitted to the ground station after capturing the satellite images, many image pre/post-processing steps are involved. During the pre/post-processing, when converting from level 1R images to level 1G images, geometric correction is essential. An interpolation method necessary for geometric correction is inevitably used, and the quality of the level 1G images is determined according to the accuracy of the interpolation method. Also, it is crucial to speed up the interpolation algorithm by the level processor. In this paper, we proposed a lightweight CNN-based interpolation method required for geometric correction when converting from level 1R to level 1G. The proposed method doubles the resolution of satellite images and constructs a deep learning network with a lightweight deep convolutional neural network for fast processing speed. In addition, a feature map fusion method capable of improving the image quality of multispectral (MS) bands using panchromatic (PAN) band information was proposed. The images obtained through the proposed interpolation method improved by about 0.4 dB for the PAN image and about 4.9 dB for the MS image in the quantitative peak signal-to-noise ratio (PSNR) index compared to the existing deep learning-based interpolation methods. In addition, it was confirmed that the time required to acquire an image that is twice the resolution of the 36,500×36,500 input image based on the PAN image size is improved by about 1.6 times compared to the existing deep learning-based interpolation method.

A conventional phased array system can control an ultrasonic beam electronically by adjusting the excitation time delay of individual elements in a multi-element probe and produce an ultrasonic image. In Contrast, full matrix capture (FMC) is a data acquisition process that allows receiving ultrasonic signals from one single shot of the phased array transducer element through all the other elements and captures the complete dataset from every possible transmit-receive combination. This FMC data can be used to create the ultrasonic image in post processing. It is possible to produce not only images equivalent to conventional phased array image but also total focusing method (TFM) images with improved resolution and sharpness, which is virtually focused at any point in a region of interest. In this paper, the system that can perform FMC by using a conventional phased array instrument is developed, and a study was conducted on the imaging algorithms to reconstruct sector B-scan and TFM images from FMC dataset.

This study is intended to observe the meaning, aesthetic formative characteristics of the human body which is introduced and applied to the fashion design. The analysis of the modern fashion design describing the human body refers to the extracted fashion design which expresses the human body appearing in domestic & foreign fashion magazines as well as publications associated with it and published since 1990. The analysis of the way of expression, the image and the design elements in these fashion design works, has had to formative characteristics in each of the three parts. The pursuit of formative characteristics through simplifying the expression of the human body, uprising of anatomical expression, and metaphorical expression with the help of personification and objectification can be thought of as characteristics of expressing pattern. And the op-art, optical illusion by virtue of pointillism, the use of non-woven molding, and action painting technique can be described as expression tools to recognize the human body. Images are presented in the characteristics of being grotesque, humorous, erotic, futuristic and mysterious. The characteristics of designs are expressed in creative detail, trimming, pattern and accessory using the form of human body itself as an item of clothing tends to show the unity of human body and clothing. The human body in the modern era reflects the post human image as well as its meaning as a medium and tool. It is also perceived as a specific object to be self-conscious of in this reality with the loss of humanity, alienation and the confusion of identity. The analysis of the image and way of expression of human body in the fashion design, and the meaning of human body will play an important role of identifying tole viewpoint about human body as well as prospecting what the human being will be in the future.

For generating accurate land cover map over the whole Korean Peninsula, post-mosaic classification method is desirable in large area where multiple image data sets are used. We try to derive an optimal mosaic method of multi-temporal Landsat ETM+ scenes for the land cover classification over the Korea Peninsula. Total 65 Landsat ETM+ scenes were acquired, which were taken in 2000 and 2001. To reduce radiometric difference between adjacent Landsat ETM+ scenes, we apply three relative radiometric correction methods (histogram matching, 1st-regression method referenced center image, and 1st-regression method at each Landsat ETM+ path). After the relative correction, we generated three mosaic images for three seasons of leaf-off, transplanting, leaf-on season. For comparison, three mosaic images were compared by the mean absolute difference and computer classification accuracy. The results show that the mosaic image using 1st-regression method at each path show the best correction results and highest classification accuracy. Additionally, the mosaic image acquired during leaf-on season show the higher radiance variance between adjacent images than other season.

When designing reinforced concrete (RC) members, the rebar is assumed to resist all tensile forces, but the resistance of the concrete in the tension area is neglected. However, concrete can also resist tensile forces and increase the tensile stiffness of RC members, which is called the tension stiffening effect (TSE). Therefore, this study assessed the TSE, particularly after yielding of the steel bars and the effects of the steel ratio on the TSE. For this purpose, RC member specimens with steel ratios of 2.87%, 0.99%, and 0.59% were fabricated for uniaxial tensile tests. A vision-based non-contact measurement system was used to measure the behavior of the specimens. The cracks on the specimen at the stabilized cracking stage and the fracture stage were measured with the image analysis method. The results show that the number of cracks increases as the steel ratio increases. The reductions of the limit state and fracture strains were dependent on the ratio of the rebar. As the steel ratio decreased, the strain after yielding of the RC members significantly decreased. Therefore, the overall ductility of the RC member is reduced with decreasing steel ratio. The yielding plateau and ultimate load of the RC members obtained from the proposed equations showed very good agreement with those of the experiments. Finally, the image analysis method was possible to allow flexibility in expand the measurement points and targets to determine the strains and crack widths of the specimens.

Objectives: Loss of the interdental papilla is multi-factorial and creates a multitude of problems. Autogenous connective tissue/biomaterial-based regeneration has been attempted for decades to reconstitute the black space created due to the loss of papilla. The aim of this present study was to regenerate papillary recession defects using an amnion-chorion membrane (ACM) allograft and to evaluate the clinical outcome up to six months postoperatively. Materials and Methods: Twenty patients with 25 Nordland and Tarnow's Class I/II interdental papillary recession defects were treated with ACM and coronal advancement of the gingivo-papillary unit via a semilunar incision on the labial aspect followed by a sulcular incision in the area of interest. A photographic image analysis was carried out using the GNU Image Manipulation software program from the baseline to three and six months postoperatively. The black triangle height (BTH) and the black triangle width (BTW) were calculated using the pixel size and were then converted into millimeters. The mean and standard deviation values were determined at baseline and then again at three and six months postoperatively. The probability values (P<0.05 and P≤0.01) were considered statistically significant and highly significant, respectively. An analysis of variance and post hoc Bonferroni test were carried out to compare the mean values. Results: Our evaluation of the BTH and BTW showed a statistically and highly significant difference from the baseline until both three and six months postoperatively (P=0.01). A post hoc Bonferroni test disclosed a statistically significant variance from the baseline until three and six months postoperatively (P<0.05) and a non-significant difference from three to six months after the procedure (P≥0.05). Conclusion: An ACM allograft in conjunction with a coronally advanced flap could be a suitable minimally invasive alternative for papillary regeneration.

Objective: To compare a deep learning-based reconstruction (DLR) algorithm for pediatric abdominopelvic computed tomography (CT) with filtered back projection (FBP) and iterative reconstruction (IR) algorithms. Materials and Methods: Post-contrast abdominopelvic CT scans obtained from 120 pediatric patients (mean age ± standard deviation, 8.7 ± 5.2 years; 60 males) between May 2020 and October 2020 were evaluated in this retrospective study. Images were reconstructed using FBP, a hybrid IR algorithm (ASiR-V) with blending factors of 50% and 100% (AV50 and AV100, respectively), and a DLR algorithm (TrueFidelity) with three strength levels (low, medium, and high). Noise power spectrum (NPS) and edge rise distance (ERD) were used to evaluate noise characteristics and spatial resolution, respectively. Image noise, edge definition, overall image quality, lesion detectability and conspicuity, and artifacts were qualitatively scored by two pediatric radiologists, and the scores of the two reviewers were averaged. A repeated-measures analysis of variance followed by the Bonferroni post-hoc test was used to compare NPS and ERD among the six reconstruction methods. The Friedman rank sum test followed by the Nemenyi-Wilcoxon-Wilcox all-pairs test was used to compare the results of the qualitative visual analysis among the six reconstruction methods. Results: The NPS noise magnitude of AV100 was significantly lower than that of the DLR, whereas the NPS peak of AV100 was significantly higher than that of the high- and medium-strength DLR (p < 0.001). The NPS average spatial frequencies were higher for DLR than for ASiR-V (p < 0.001). ERD was shorter with DLR than with ASiR-V and FBP (p < 0.001). Qualitative visual analysis revealed better overall image quality with high-strength DLR than with ASiR-V (p < 0.001). Conclusion: For pediatric abdominopelvic CT, the DLR algorithm may provide improved noise characteristics and better spatial resolution than the hybrid IR algorithm.

The female image has been changed incessantly with age and has been eminently represented in cosmetic advertisement. The female images are changed from the classical images to the active and professional images with the historical current of cyber, digital, and fusion. These changes in the expression of female image are largely due to the spread of post-modernism, feminism, de-construction (Kim, 1994), digital information revolution, and increase of income. The female images in cosmetic advertisement have been expressed very variously with fashion, marketing target, and characteristics of articles. (Im, 1997) The cosmetic advertisements of pure and graceful images were popular in the past. But nowadays individual image, womanly image, and unchanged beautiful image are in vogue. Individual image is very popular in young generation with very short fashion period. Active career woman image represents passion and beauty with extension of women' social roles. Unchanged beautiful image in modern industrial pollution stands for the desire of keeping the beauty in youth. Brand is very important factor to consumers in purchasing. Brand is no larger the simple concept in the past, and accepted as reflection of the image, social status, service, and life-style(Lee, 1998) consumers are very favorable to foreign cosmetics with the increase of overseas travels and import. This phenomenon is considered as very natural, especially in young generation. To create a successful brand image, the harmony of quality, psychological preference, advertisement, and reasonable price are required. According to the questionnaire research implemented by the subject of college women students in five universities in Seoul, the majority of college women students purchase domestic cosmetic brands in cosmetic specialty stores and depend on the tips of acquaintances. Quality, skin-trouble, and brand are considered as special regards for purchasing. Especially, internet shopping in purchasing marks high growth rate and preference for foreign cosmetics is very ardent. It can be expected that the 21st century is the epoch of various small production different from the mass-production in the 20th century. Female image will be probably expressed with individual, emotional, and professional image in the media of digital, fusion, cyber, and technology culture. It can be said that the tendency of cosmetic purchasing in the future will be more focused on brand image and life style.

Recently, 3D technology based on depth image is widely used in various fields including 3D space recognition, image acquisition, interaction, and games. Depth camera is used in order to produce depth image, various types of effort are made to improve quality of the depth image. In this paper, we suggests using area-based Canny edge detector to improve depth image in applying 3D technology based on depth camera. The suggested method provides improved depth image with pre-processing and post-processing by fixing image quality deterioration, which may take place in acquiring depth image in a limited environment. For objective image quality evaluation, we have confirmed that the image is improved by 0.42dB at maximum, by applying and comparing improved depth image to virtual view reference software. In addition, with DSCQS(Double Stimulus Continuous Quality Scale) evaluation method, we are reassured of the effectiveness of improved depth image through objective evaluation of subjective quality.
