To investigate the expression patterns of proteins and growth factor signals in differentiated rabbit embryonic stem (ES) cells, ES cells with confluent stage grown of feeder layer and differentiated cells into embryoid bodies (EB) without feeder cell were applied to protein gel and Western blotting analysis. There were 66kDa and 28kDa specifically expressed in differentiated ES cell but not in undifferentiated ES cell while 25kDa protein band showed up in only undifferentiated ES cells. Also there were some difference of protein bands in several area of gel between differentiated and undifferentiated ES cells such as about 100 kDa, 50kDa and 27kDa areas, but there was no difference in band pattern of one-dimensional gel analysis between mouse ES cells and rabbit ES cells. IGF-I receptor and EGF receptor were expressed in differentiated cells and undifferentiated cells. And ICF-I and EGF were not expressed in both differentiated and undifferentiated cells. These results indicated that ES cells express their own proteins to inhibit differentiation while EB cells synthesize different proteins to differentiate, and 16F-I receptor and EGF receptor were expressed in both ES and EB cells probably for the different functions.

Festival costume shown in festival parades targeting historical events or figures helps to understand the theme of festival and grants visual effects and at the same time, is an important factor to identify then-cultural environment. Accordingly, this study aims to make a periodic review of traditional costumes used in parades for Hanseong Baekje Cultural Festival and Yeongam Wangin Cultural Festival which are both the festivals that backgrounded Baekje period, make a comparative analysis of the archetypes of reproduction costume vs Baekje costume, understand the problems of festival costume, and seek developmental directions. After making a comparative analysis of reproduction costume shown in festival parades, it was found that king costume, queen costume, governmental official costume, and humble class costume were all different from Baekje costume in terms of configuration, materials, color, shape, and creating method of costumes, and problems were drawn. When it comes to costume items, Pasul and Danryungpoh that didn't belong to Baekje period were worn. The problems in color research can be identified in governmental official costume. The problems in type of costume are shown in the length of po worn outside, margin of width, and degree of restoring accessories. Therefore, it seems to be necessary to convey and identify costume creating method by festival parade-related persons.

Background Lipedema is a condition consisting of painful bilateral increases in subcutaneous fat and interstitial fluid in the limbs with secondary lymphedema and fibrosis during later stages. Combined decongestive therapy (CDT) is the standard of care in most countries. Since the introduction of tumescent technique, liposuction has been used as a surgical treatment option. The aim of this study was to determine the outcome of liposuction used as treatment for lipedema. Methods Twenty-five patients who received 72 liposuction procedures for the treatment of lipedema completed a standardized questionnaire. Lipedema-associated complaints and the need for CDT were assessed for the preoperative period and during 2 separate postoperative follow-ups using a visual analog scale and a composite CDT score. The mean follow-up times for the first postoperative follow-up and the second postoperative follow-up were 16 months and 37 months, respectively. Results Patients showed significant reductions in spontaneous pain, sensitivity to pressure, feeling of tension, bruising, cosmetic impairment, and general impairment to quality of life from the preoperative period to the first postoperative follow-up, and these results remained consistent until the second postoperative follow-up. A comparison of the preoperative period to the last postoperative follow-up, after 4 patients without full preoperative CDT were excluded from the analysis, indicated that the need for CDT was reduced significantly. An analysis of the different stages of the disease also indicated that better and more sustainable results could be achieved if patients were treated in earlier stages. Conclusions Liposuction is effective in the treatment of lipedema and leads to an improvement in quality of life and a decrease in the need for conservative therapy.

Purpose: The purpose of this study is to analyze the factors that affect ammunition performance by applying data mining techniques to the Ammunition Stockpile Reliability Program (ASRP) data of the 155mm propelling charge. Methods: The ASRP data from 1999 to 2017 have been utilized. Logistic regression and decision tree analysis were used to investigate the factors that affect performance of ammunition. The performance evaluation of each model was conducted through comparison with an artificial neural networks(ANN) model. Results: The results of this study are as follows; logistic regression and the decision tree analysis showed that major defect rate of visual inspection is the most significant factor. Also, muzzle velocity by base charge and muzzle velocity by increment charge are also among the significant factors affecting the performance of 155mm propelling charge. To validate the logistic regression and decision tree models, their classification accuracies have been compared with the results of an ANN model. The results indicate that the logistic regression and decision tree models show sufficient performance which conforms the validity of the models. Conclusion: The main contribution of this paper is that, to our best knowledge, it is the first attempt at identifying the significant factors of ASPR data by using data mining techniques. The approaches suggested in the paper could also be extended to other types ammunition data.

The purpose of this study was to find the effects of the eccentric exercise induced delayed muscle soreness on proprioception, muscle strength, muscle fatigue, and muscle pain of the elbow flexor muscles. Thirty one healthy male subjects were participated in this study. Before resisted eccentric exercise of the elbow flexors and immediately and at 1, 3, 5, and 7 days post-exercise, pain threshold, proprioception, tension tracking, initial median frequency, and fatigue index were measured. Pain pressure threshold and visual analog scale (VAS) was used to measure muscle pain. Proprioception of the elbow joint was measured by using 3 dimension motion analysis system. Maximum isometric contraction was measured by using digital tensiometer. Electromyography and power spectrum analysis was used to measure initial median frequency (IMF) and fatigue index (FI). Immediately post-exercise, a significant decrease pain threshold was observed that continued to 5 days post-exercise. VAS score was significantly increased at 1 and 3 days post-exercise compared to that of immediately post-exercise. Maximum isometric contraction, IMF, tension tracking ability of the exercised elbow joint were significantly decreased at 1, 3, and 5 days post-exercise compared to that of pre-exercise. FI was significantly increased at 1 and 3 days post-exercise compared that of pre-exercise. Proprioception sense of exercised elbow joint was significantly decreased immediately and at 1, 3, and 5 days post-exercise compared to that of pre-exercise. Proprioception sense of the contralateral elbow joint was significantly decreased immediately post-exercise compared to that of pre-exercise. However, proprioception sense that was measured in close chain kinematic position was not significantly difference between pre-exercise and post-exercise. These results could be useful to determine the resume time for exercising and participating sports activities.

This research investigates the influence of color as an important factor of the visual image created by clothes. First, the factor analysis of the adjectives describing the images of clothes shows that the images of clothes are classified into 4 factors that include attraction, brightness, femininity, and the figure type (of which the attraction factor and brightness factor were found to be important dimensions). Second, as for the images of feminine style clothes colors, violet appears more refined and attractive than other colors in all 3 tones. Red appears as a brilliant and glowing image in a vivid tone. Yellow in a vivid tone and pale tone, and red in deep tone appear as a warm image, while blue appears as a cold image in all 3 tones. Blue and violet appear as a tall and slim image in all 3 tones. As for the images of mannish style clothes colors, yellow in vivid tone, violet in pale tone and red in deep tone appear as the most refined and attractive image, while green in all the tones appears as a rustic and unattractive image. Red in vivid tone, yellow in pale tone and violet in deep tone appear as a very brilliant and glowing image. Red in pale tone and deep tone appear as a warm and feminine image. Third, yellow in all the tones is evaluated to be attractive in the mannish style in the comparison of the image of feminine and mannish style clothes color, while blue in a pale tone in feminine style and in deep tone in mannish style earned high points. Red and violet did not show any significant differences between the two styles.

Large pressure on the growing population has increased rapid change in the LULC (land use/land cover) patterns in the watershed area. Spatial distribution of LULC information and its changes are desirable for any effective planning, managing and monitoring activities. The aim of the study is to produce the 1,50,000 scaled LULC change map for the sub-watershed, Western Moyar, India using the multi-temporal satellite image dataset of IRS LISS III images for the year 1989, 1999, and 2002. About 9 classes are extracted using onscreen visual interpretation techniques for all the three years. The change detection analysis was performed using matrix method for period I (1989-1999) and period II (1999-2002). The study reveals that the changes noticed in period II (1999-2002) is comparatively more than period I (1989-1999), which is dynamic information to protect the sub-watershed area from the deterioration and paves the way to for the sustainable development.

This study mathematically and scientifically investigated the aesthetic consciousness of women inherent in the costume craftworks craftworks of the Chosun Dynasty through a systematical analysis of their textile pattern composition using visual language theory. The tangent value from the horizontal and vertical ratio of the costume craftworks craftworks indicated that they had an indigenous proportion system with a relatively regular form and pattern but without an exaggerated type. There was a module based on structures in the textile patterns of the costume craftworks craftworks and the patterns were constructed by the module with the syntagms of the ratio structure. Moreover, the analysis of the pattern designs indicated that the whole form of the costume craftworks craftworks was built through a repetitive structure of feature and one of pattern units; in addition, the craftworks had the extended composition and blank space of daring patterns, an important factor to make a whole design. Therefore, our study suggested that the costume craftworks craftworks of the Chosun Dynasty was characterized by the presentation of the aesthetic style with a Geumgang ratio (an indigenous proportion system used in Korea) and could be interpreted as an art style based on the beauty of space. Moreover, it is suggested that the spirit inherent in the costume craftworks of the Chosun Dynasty (which tried to understand the whole as one and equate the whole and parts) might agree with a holistic tendency as the foundation of Korea art.

This paper presents a piecewise image denoising with multi-scale block region detector based on quadtree structure for effective image restoration. Proposed piecewise image denoising method suggests multi-scale block region detector (MBRD) by dividing whole pixels of a noisy image into three parts, with regional characteristics: strong variation region, weak variation region, and flat region. These regions are classified according to total pixels variation between multi-scale blocks and are applied principal component analysis with local pixel grouping, bilateral filtering, and structure-preserving image decomposition operator called relative total variation. The performance of proposed method is evaluated by Experimental results. we can observe that region detection results generated by the detector seems to be well classified along the characteristics of regions. In addition, the piecewise image denoising provides the positive gain with regard to PSNR performance. In the visual evaluation, details and edges are preserved efficiently over the each region; therefore, the proposed method effectively reduces the noise and it proves that it improves the performance of denoising by the restoration process according to the region characteristics.
