  • Conversion Disorder is a disorder whose predominant feature is a loss or alteration in physical functioning that suggests a physical disorder but that is actually a direct expression of a psychological conflict or need. The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) guidelines for Conversion Disorder include these definitions: A psychosocial stressor produces a psychological conflict that is believed to help initiate or exacerbate the illness The symptoms are not under conscious control, etc. While functional disabilities are common with conversion disorders, physical and laboratory abnormalities are absent or minor in comparison with the patient's subjective complaints. Symptoms of Conversion Disorder are similar to those of stroke. But the mechanism of Conversion Disorder is similar as that of Stagnation Syndrome of Ki (氣鬱證) in Oriental medicine. Gaegyeolseogyeong-tang has been used to treat women who suffer from Conversion Disorder induced by the Stagnation Syndrome of Ki (氣鬱證). After application of the Gaegyeolseogyeong-tang for 7 days, symptoms and signs improved dramatically.

  • Purpose: Among RF pulses, a sinc pulse is typically used for slice selection due to its frequency-selective feature. When a sinc pulse is implemented in practice, it needs to be apodized to avoid truncation artifacts at the expense of broadening the transition region of the excited-band profile. Here a sinc pulse tailored by a new apodization function is proposed that produces a sharper transition region with well suppression of truncation artifacts in comparison with conventional tailored sinc pulses. A multiband pulse designed using this newly apodized sinc pulse is also suggested inheriting the better performance of the newly apodized sinc pulse. Materials and Methods: A new apodization function is introduced to taper a sinc pulse, playing a role to slightly shift the first zero-crossing of a tailored sinc pulse from the peak of the main lobe and thereby producing a narrower bandwidth as well as a sharper pass-band in the excitation profile. The newly apodized sinc pulse was also utilized to design a multiband pulse which inherits the performance of its constituent. Performances of the proposed sinc pulse and the multiband pulse generated with it were demonstrated by Bloch simulation and phantom imaging. Results: In both simulations and experiments, the newly apodized sinc pulse yielded a narrower bandwidth and a sharper transition of the pass-band profile with a desirable degree of side-lobe suppression than the commonly used Hanning-windowed sinc pulse. The multiband pulse designed using the newly apodized sinc pulse also showed the better performance in multi-slice excitation than the one designed with the Hanning-windowed sinc pulse. Conclusion: The new tailored sinc pulse proposed here provides a better performance in slice (or slab) selection than conventional tailored sinc pulses. Thanks to the availability of analytical expression, it can also be utilized for multiband pulse design with great flexibility and readiness in implementation, transferring its better performance.

  • The 21st century is the age when a sensational image has more explanatory power and can deliver a more powerful message than a message consisting of logical thinking. Powerful visual images create a big impact on many people throughout the world, overcoming linguistic barriers and even replacing language as a means of communication. In the fashion field, the concept and power of visual images within the new multimedia of the 21st century are becoming increasingly important. In recent years, other than the above methods, videos, movies and animation features have been produced directly to enhance visual effects and attempts are increasing to use these new tools as communication methods. This study focuses on animation contents that have been used in the fashion industry to overcome prejudice of luxury international brands that feature images that emphasize value, quality and heritage. The purpose of this study is to focus on the specific character of fashion animation in order to overview the concept of 21st video fashion communication and to show how the collection concept that includes color and detail places an emphasis on visual images. Analysis of previous research, theoretical research through literature and case study on Prada fashion animation led to the following conclusion. The common features of two different Prada fashion animation show that both animation have the following features in common : realism, dramatic impact and convergence for expression methods, and creativeness, hybrid and a happy ending for contents. Beginning with this study, I believe that various angles of interest and concern about communication in the fashion world, which is a social and cultural phenomenon that changes rapidly, can be will be looked at and learned from.

  • Therapeutic angiogenesis is the controlled induction or stimulation of new blood vessel formation to reduce unfavourable tissue effects caused by local hypoxia and to enhance tissue repair. Therapeutic ultrasound can be considered as a physical agent to deliver therapeutic angiogenesis. The purpose of this study was to evaluate the effect of therapeutic ultrasound after muscle contusion injury by observed immunoreactivity of vascular endothelial growth factor(VEGF) that plays an important role in angiogenesis and substance-P in pain transmission. Ultrasound irradiation(1MHz, $1W/cm^2$, continuous mode, treatment time 5 min) was applied through water submersion technique to 1 limb daily by kept off 5cm from muscle belly of gastrocnemius. The result of this study were as follows. 1. In morphological observation, there were no significant changes excepts of 7 days. At 7 days, granular tissue viewed abundantly in control group. In other groups, general feature were increased interspace of muscle fiber; centronucleated muscle fiber; collapsed of muscle and nerve tissue; appeared inflammatory cell. 2. The VEGF was expressed in interspace of muscle fiber. Especially, at 7 days in experimental group, VEGF was showed in connective tissue surrounding gastrocnemius muscle. 3. The VEGF was higher expressed in experimental group at 2 and 3 days, but in control group at 7 days. These data suggest therapeutic ultrasound enhanced production of VEGF in the early day relatively, therefore stimulated angiogenesis in the skeletal muscle induced contusion injury. Also therapeutic ultrasound may stimulate pain relief by diminish of substance-P in dorsal horn of spinal cord.

  • 본 논문은 K-L 변환을 기반으로 한 Fisherface 알고리즘과 fixed graph matching (FGM) 방법을 이용하여 보다 효율적인 얼굴 인식 방법을 제안하고자 한다. 동적 링크 구조 방법 중에 하나인 elastic graph matching (EGM)은 얼굴의 모양 정보뿐만 아니라, 영상 픽셀의 그레이 정보를 동시에 이용하는 하며, 클래스를 구분하는 방법인 Fisherface 알고리즘은 빛의 방향 및 얼굴 표정과 같은 영상의 변화에 대해 강인하다고 알려져 있다. 위의 두 방법으로부터 제안한 알고리즘에서는 영상 그래프의 각 노드에 대해 Fisherface방법을 적용함으로써 레이블된 그래프 벡터의 차원을 줄일 뿐만 아니라 효율적으로 클래스를 구분하기 위한 특징 벡터를 제공한다. 그럼으로써 기존의 EGM 방법에 비해 인식 속도 면에서 상당한 향상 결과를 얻을 수 있었다. 특히, Olivetti Research Laboratory (ORL) 데이터베이스와 Yale 대학 데이터베이스에 대해 실험한 결과 제안한 얼굴 인식 알고리즘은 hold-out 방법에 의한 실험 결과, 평균 90.1%로 기존의 한 방법만을 사용한 것보다 높은 인식률을 보였다.

  • In this study, the current status of product information of functional outdoor jackets in the hang-tags was investigated in perspective of consumer protection. Effectiveness and preferred alternatives to hang-tag information were also investigated. For the market survey, 1560 hang-tags from 676 functional outdoor jackets were investigated. For the effectiveness and preferred alternatives, 472 adults in their 20-60's were surveyed. The average number of hang-tags was 2.3 but 5.9% did not provide any product information. The contents included functional property of fabric; quality guarantee; brand introduction; product characteristics; instructions for care/usage; subsidiary material information, and they were different depending on end-use of jackets. Consumers strongly wanted explanations of the terms used in the hang-tag and could not accurately figure out the functions of the products from hang-tag information regardless of expression methods. The percentage of incorrect answer of 'figure/foreign language' method was extremely high. It is a noticeable feature of graph method that customers perceived that the graph was difficult to understand, but the percentage of correct answers was much higher than other methods, implying that graph method was possibly more useful at delivering accurate information to the customers who pursuit information. Customers strongly agreed to need of alternative methods and preferred an unified performance grade from selected functions based on the end-use of products. Customers also wanted to include the information of performance change after laundering. The results could provide practical insights to the consumers, companies, and the government to prepare proper guideline/policies for consumer protection.

  • Background: Prostate cancer is one of the main causes of cancer death, and drug resistance is the leading reason for therapy failure. However, how this occurs is largely unknown. We therrfore aimed to study the response of DU145 cells to cisplatin. Materials and Methods: Du145 prostate cancer cells were treated with a low dose of cisplatin for 24 h and cell viability and number were determined by MTT assay and trypan blue exclusion assay, respectively. The real time polymerase chain reaction (PCR) was used to assess responses to cisplatin treatment. Results: After 24h $2{\mu}g/ml$ treatment did not result in significant reduction in cell viability or number. However, it led to enhanced cancer cell invasiveness. E-cadherin mRNA was reduced, and vimentin, Snail, Slug, metalloproteinase 9 (MMP9) mRNA expression increased significantly, a feature of epithelial-mesenchymal transition (EMT). Conclusions: Short time low concentration cisplatin treatment leads to elevated invasiveness of DU145 cancer cells and this is possibly due to EMT.

  • The so-called 'Bustle'which was a support put on waist to heave the side the buttocks means the grandiloquent style to express to ideal body. Bustle style. one of the outstanding and remarkable fashion trends in the late 20th century, has significant meaning in fashion history. This is because not only the style has the longest history, but also it has been periodically repeated every end of a century from the 17th to the 20th century. To analyse to cause the Bustle style was shown, I studied first the sign of forthcoming activity of the Bustle style, the change of the Bustle style shown In the times at the end of century and feature of the Bustle style. Based on the previous reasons of appearance of the Bustle style In the history. there are two similarities. First. reaction led to an occurrence of the reactionary tendency, the Bustle style as they were eager for the past because of a feeling of uneasiness about a coming century. Second, the principle of retrogression led to an occurrence of the Bustle style craving for new style. This Bustle style welch was reaction from being tired of the former fashion appeared to expression a desire for new style. In short, Bustle style was an intermediation between different histories and the basis for continuous development of new eras. rather than lust a part of classicism.
