The purpose of this study is to investigate fatigue phenomema of woven fabric. In order to obtain the basic data which is available for predicting the fabric fatigue phenomena, the change of mechanical properties of woven fabrics caused by the wearing and the changes of mechanical properties of woven fabrics which were subjected to repeated tensile-shearing deformation using fabric testing machine has been investigated and compared. The fatigue of woven fabrics was examined with the value of basic mechanical properties of specimens measured by the KES-F fabric testing system and their hand value and wearing ability. The results were as follows. 1) The fatigue phenomena of woven fabrics by the wearing for 800 hours are different on the position of the body: On the portion of hip, the change of surface property was the greatest, bending hysterisis was greatly increased, thickness weight, stiffness, fullness shearing hysterisis were more increased than original fabric and T.H.V. was decreased. On the portion of knee, decreasing of tensile resilience and increasing of bending, shearing hysterisis were observed greater than any other part, and increasing of stiffness, crispness was more than original fabric. On the bottom area, the changes of mechanical property was comparatively small, H.V. and T.H.V. showed near the value of the original fabric. 2) By drycleaning most of mechanical properties showed the tendency to recover the value of the original fabric, but bending hysterisis and thickess were increased, tensile and com-pression resilience were decreased more than original fabric in all parts. 3) The fatigue phenomena caused by fabric fatigue testing machine were as follows. The decreasing of hystersis in the repeated deformation such as bending, shearing was appeared at the $10^2$ deformation, but with the increasing cycle, the tendency was slightly regained. Handle value was also appeared the lowest value at the $10^2$ deformation.

Two solution approaches have been suggested globally to solve the crisis of bill of lading; that is to say, electronic bill of lading and sea waybill. Electronic bill of lading is not unsettled as a solution to solve the crisis of bill of lading but sea waybill is used on a global basis to do so. The surrendered bill of lading is applied for practical usage instead of sea waybill in a short voyage among Korea, China, and Japan, owing to faster delivery at destination and lower cost than bill of lading. To surrender the original bill of lading, the consignor should submit all originals with a request letter to the carrier of goods with necessary surrender charges, if any, in doing so. Once after receiving the original bills of lading consisting of normally three originals but in some cases five, the carrier stamped "Surrendered" on the front of original bills of lading and sent a message to his counterpart at the port of destination, stating that the original bill of lading surrendered at the port of shipment and the consignee can take delivery of the goods without production of the original bill of lading at destination. The legal regime of the surrendered bill of lading is not settled as it is not considered legally as bill of lading, and the decisions rendered by each nation's courts are different according to the usages of the surrendered bill of lading. The purpose of this paper is to prevent the disputes between parties with regard to the surrendered bill of lading by studying the causes and precautions of disputes in relation to the surrendered bill of lading.

We studied on the purpose of comparing the original texts with quotations in edema chapter of Dong- Yi-Bo-Gam. The research mainly depended on compare and consider these original text and quote. In Pyong Yeol Byong chapter of SoMoon, Su Yeol Hyul chapter of SoMoon, Pyong Yin Ki Sang chapter of SoMoon, Ja Jeol Jin Sae chapter of YoungChu, Emperor's Classic of Internal Medicine(黃帝內經;ECIM), We were able to find that some sentences about edema were quoted. Drug arrangement order that construct herb medicine is disposed depends on drug's weight, and all unit was concorded by Jeon and Pun. Quoted words in Emperor's Classic of Internal Medicine(黃帝內經;ECIM) does not perfectly match with original text. However, edema chapter of Dong- Yi-Bo-Gam is identical with original text, because only few words were deleted or inserted.

In recent years, the obfuscation techniques are commonly exploited to protect malwares, so obfuscated malwares have become a big threat. Especially, it is extremely hard to analyze virtualization-obfuscated malwares based on unusual virtual machines, because the original program is hidden by the virtual machine as well as its semantics is mixed with the semantics of the virtual machine. To confront this threat, we suggest a framework to analyze virtualization-obfuscated programs based on the dynamic analysis. First, we extract the dynamic execution trace of the virtualization-obfuscated executables. Second, we analyze the traces by translating machine instruction sequences into the intermediate representation and extract the virtual machine architecture by constructing dynamic context flow graphs. Finally, we extract abstract semantics of the original program using the extracted virtual machine architecture. In this paper, we propose a method to extract the information of the original program from a virtualization-obfuscated program by some commercial obfuscation tools. We expect that our tool can be used to understand virtualization-obfuscated programs and integrate other program analysis techniques so that it can be applied to analysis of the semantics of original programs using the abstract semantics.

Lately, digital restitution was became common using digital aerial photos. Therefore, we can obtain three-dimensional data. As a plotting-maker is checked by naked eye, plotting original data is very useful for making reliable three-dimensional data including contour and elevation point layers. In this study, we want to make precise and accurate digital elevation model using plotting original data. Contour and elevation point layers was extracted in digital map and break line was extracted in plotting original data. And then, compared both of results. For comparison, we selected slight slope and complex topography area like a residence area, mountain and agricultural land. We extracted break line deleting layer until obtaining ideal digital elevation model. As the results, We could extract contour, elevation points, eight road and two boundary layers using break lines. And We could obtain precise elevation model. Editing break lines, the distortion of digital elevation model could be minimized in the complex and sharp slope area.

Objectives : The Major Essentials of Huangdi's Internal Classics Plain Questions (黃帝內經素問大要, MEHP) is one of the late-Chosun's literate physician Lee Gyoojoon (李圭晙, 1885-1923)'s main work, which is known to have logically proofread the Huangdi's Internal Classics Plain Questions (黃帝內經素問, HP). This study aims to examine two elements of the text: (1) the types of MEHP currently in circulation; (2) the types of publications of HP to be the MEHP's original script. Methods : In this study, basically bibliographical analyses of the form and contents was utilized about the types of MEHP and HP. However, to compare the sentences and phrases between prints, I've used 20 examples that Qian Chaochen (钱超尘) had proposed in his preceding studies. Also, regarding Lee Wonse (李元世)'s proofreading on the MEHP in 1999, I've used interviews of his students. Results : First, I've discovered that there are three versions MEHP in circulation: the woodblock printed version; Lee Wonse's handwritten version; Lee Wonse's proofreading version; and confirmed that Lee's proofreading version should be regarded as good version of MEHP. Also, I've discovered the possibility of other types of printed versions of the MEHP in existence, which is considered Lee's handwritten version's original draft. Second, I've confirmed that the original script of HP, which Lee Gyoojoon utilized for MEHP, is indeed not Gu Congde (顧從德) printed version HP, however, is the Chosun's bureau for military drill (訓練都監) printed version HP. Conclusion : Through this study, I've provided strong evidence that Lee Gyoojoon's MEHP is a unique and original research completed within the traditional realm of Korean medicine, which possesses the universality of Eastern Asian medicine represented by Huangdi's Internal Classics (黃帝內經).

This paper proposes a digital image watermarking which is robust to geometric distortions using an independent component analysis(ICA) of fixed-point(FP) algorithm based on secant method. The FP algorithm of secant method is applied for better performance in a separation time and rate, and ICA is applied to reject the prior knowledges for original image, key, and watermark such as locations and size, etc. The proposed method embeds the watermark into the spatial domain of original image The proposed watermarking technique has been applied to lena, key, and two watermarks(text and Gaussian noise) respectively. The simulation results show that the proposed method has higher speed and better rate for extracting the original images than the FP algorithm of Newton method. And the proposed method has a watermarking which is robust to geometric distortions such as resizing, rotation, and cropping. Especially, the watermark of images with Gaussian noise has better extraction performance than the watermark with text since Gaussian noise has lower correlation coefficient than the text to the original and key images. The watermarking of ICA doesn't require the prior knowledge for the original images.

Purpose: The aims of the present study are to determine the optimum compression rate in terms of file size reduction and diagnostic quality of the images after compression and evaluate the transmission speed of original or each compressed image. Materials and Methods: The material consisted of 24 extracted human premolars and molars. The occlusal surfaces and proximal surfaces of the teeth had a clinical disease spectrum that ranged from sound to varying degrees of fissure discoloration and cavitation. The images from Digora system were exported in TIFF and the images from conventional intraoral film were scanned and digitalized in TIFF by Nikon SF-200 scanner (Nikon, Japan). And six compression factors were chosen and applied on the basis of the results from a pilot study. The total number of images to be assessed were 336. Three radiologists assessed the occlusal and proximal surfaces of the teeth with 5-rank scale. Finally diagnosed as either sound or carious lesion by one expert oral pathologist. And sensitivity, specificity and k value for diagnostic agreement was calculated. Also the area (Az) values under the ROC curve were calculated and paired t-test and oneway ANOVA test was performed. Thereafter, transmission time of the image files of the each compression level was compared with that of the original image files. Results: No significant difference was found between original and the corresponding images up to 7% (1 : 14) compression ratio for both the occlusal and proximal caries (p<0.05). JPEG3 (1 : 14) image files are transmitted fast more than 10 times, maintained diagnostic information in image, compared with original image files. Conclusion: 1 : 14 compressed image file may be used instead of the original image and reduce storage needs and transmission time.

This study aims to examine attributes of fandom related to storytelling of media conversion in terms of division of obsession and hysteria from the psychoanalysis. Fandom of crossmedia storytelling represented by adaptation of the original is the subject who experienced a great satisfaction from the original and also the obsessive subject who does not accept easily story transformation by adaptation. Besides, fandom of transmedia storytelling is the hysterical subject who recognizes lack of the storyworld and enjoys such a lack. The original fandom of crossmedia enjoys phallic order in the authority of an original author and the original storyworld, and fandom of transmedia experiences continual and infinite 'other enjoyment' through active and direct experience beyond the linguistic order. This study is a theoretical argument to identify characteristics of fandom shown from both extremes of media conversion through comparison of obsession and hysteria. It is expected to prepare a foundation for understanding fandom of media conversion through complementing qualitative analysis on the real fandom in the follow-up research.
