Objectives: Although electro-acupuncture is being utilized to reduce weight in Korea, its usefulness in obesity management has not been fully evaluated yet. The objective of this study is to evaluate the effect of Electro-acupuncture on thigh circumference. Methods: 12 healthy volunteers participated in this study. We measured the circumference of both thighs, and treated the thicker one with transcutaneous electro-acupuncture at 8 acupoints, 10 times in total. The electrical parameters were : 1st step frequency set was at 15Hz and the treatment proceeded for 50 minutes, 2nd step at 50Hz for 10 minutes and at 3rd step the acupunctures were removed and electrodes were attached on the lower limb at 166Hz for 15 minutes. In order to evaluate the effect of the treatment, total body weight, percentage of body fat and thigh circumference were measured 4 times. Before the treatment, after 5th and 10th treatment and 1 month after completion of the whole treating procedure. Statistical significance(P<0.05) was determined using the Wilcoxon signed rank test. We did not control diet, exercise and lifestyle of the volunteers. Results: No significant change was shown in body weight after 10 times of treatment. Yet the thigh circumference of effect group significantly decreased after 5th treatment and 10th treatment. The circumference of control group that was not treated by electro-acupuncture significantly decreased too. At first, difference between the two thighs in circumference was obvious, but no difference was left after 10 times of treatments on the thicker thigh. Percentage of body fat was significantly decreased. 1 month after having completed the treatment, there was no significant difference of body weight, thigh circumferences and percentage of body fat. Conclusion: These results suggest that electro-acupuncture effectively regulates regional fat, body fat percentage and body shape.

이 연구의 목적은 패션디자인에서의 형태의 중요성을 이해하는 새로운 시각을 제시하는데 있다. 뵐플린과 드롱의 이론을 바탕으로 Flat St Rounded, Closed & Opened 과 Part & Whole의 세 가지 형태를 보는 시각을 가지고 Vionnet와 Dior 작품에서의 형태미를 분석하는데 적용시켜 고찰해 보았다. Vonnet와 Dior은 그들의 디자인에서 형태와 구조를 디자인의 기본원리로 하여 기하학적인 형태를 그들의 디자인에 적용시킨 디자이너들이다. Vionnet의 10작품과 Dior의 11작품을 선정해 Belong의 visual priorities diagram을 적용시켜 각 디자이너 작품의 형태미를 고찰하고 비교해 보았다. Vionnet는 의복과 인간의 신체 사이의 관계를 통해 새로운 형태미학을 창조해 냈으며 그녀의 작품은 2차원 또는 3차원이라는 공간의 차이에 따라 형태의 전위를 보여주는 독특한 형태학적 특성을 보여주고 있다 그녀의 작품은 2차원의 공간에서는 평면적이고 닫힌 형태인 삼각형, 사각형, 원으로 구성되어 있으나 바이어스 재단에 의한 입체재단 방법을 통해 3차원의 공간에서는 입체적이고 열린 형태로의 형태변형을 한다는 특징을 나타낸다. Dior의 작품은 인체의 자연스러운 형태보다는 인위적인 형태미를 보여주고 있으며 이는 Vionnet작품과의 커다란 차이점이다. Dior은 3차원의 공간에서 구, 각기둥, 원기둥, 각뿔, 입방체와 같은 입체 기하학의 형태를 사용하여 의복의 형태를 만들어 냈고 이는 다아트 변형, 보닝, 개더, 턱, 플리츠, 셔링과 같은 구조주의적인 기술을 통해 실현되고 있다. Dior의 작품은 3차원의 공간에서 인체의 형태와는 무관한 의복 자체만의 형태를 가지고 있으며 이는 입체적이고 닫힌 형태적 특성을 가진다.

유방암은 FDG PET-CT에서 예민도는 80~96%, 특이도는 75~95% 정도이며, 유방촬영(mammography) 소견상 판단이 어려운 수진자에게 매우 유용하며, 검진으로서의 조기 암 검출을 충분히 기대할 수 있다. PET-CT에서 대부분의 검사는 앙와위(supine position)으로 검사되어 전신검사(whole body scan)에서 원형으로부터 변형된 유방영상을 획득된다. 반면에 보정구를 이용하여 복와위(prone position)으로 영상을 획득할 경우, 유방을 중력에 의존하여 보다 원형에 가깝게 표현함으로써 영상의 진단가치를 높일 수 있기에 그 유용성을 평가하였다. 유방암으로 의심되거나 확진 된 여성 환자 30명을 대상으로 하였으며, $^{18}F$-FDG 주사한 뒤 60분 후 supine position으로 whole body PET-CT scan 시행 후, 보정구를 이용하여 prone position으로 병변에 대한 추가검사(lesional scan)를 시행하였다. 각각 획득된 영상은 핵의학과 의사로부터 blind test를 하였고, PET-CT 영상의 SUV를 측정하여 분석하였다. 30명 중 27명의 환자에게서 prone자세가 진단 용이성과 정확한 판별률이 높았으며, 나머지 3명의 경우는 병소가 1 cm 이하의 크기로 인하여, MRI상에는 나타났지만 PET-CT에서는 진단에 의미있는 관찰을 할 수 없었다. supine position과 비교하여 prone position은 구조물의 중력에 의한 변형수치가 낮아, 병변의 구별이 곤란한 경우 명확하게 감별되었다. 각 자세에서 SUV분석은 유의수준 0.004로 유의하였다. Supine position을 통한 PET-CT 전신검사 후의 보정구를 이용한 prone position로 병변에 대한 lesional scan은 두 자세의 비교가 모두 가능하였으며, 경우에 따라 결정적으로 진단에 영향을 주었다. 두 가지 자세의 영상비교에 있어 prone position이 원발성(primary) 병변의 진단은 물론, 미세전이(micrometastasis)의 검출이 가능하였다. 이러한 prone position을 기반으로 구조적인 문제를 정량적 분석과 함께 극복한다면 병변의 진단에 있어 보다 유용한 진단적 정보를 얻을 수 있으리라 사료된다.

Platelets are anuclear discoid-shaped blood cells with key roles in human body. To understand the mechanisms of their activation process, it is required to have analytical imaging techniques capable of acquiring platelet images under fully hydrated conditions. Herein, for the first time, we demonstrate the capability of synchrotron-based transmission X-ray microscopy (TXM) to study platelets (resting and ADP activated) under hydrated and air-dried conditions. To confirm the biological imaging capability of TXM, fixed platelets were imaged and compared with whole mount electron microscopy (EM) images. TXM provided morphological information with sufficient spatial resolution with simple and quick sample preparation procedure. We also observed temporal changes during the platelet activation, which initially had a discoid shape (0 s), formed pseudopodia (30 s) and generated a network of fibrin (5 min). Our results clearly demonstrate the potential of TXM technique to study fully hydrated biological samples under in situ conditions.

Objective & Method : We investigated the identity of tri-energizer, which was originally described in Huang Di Nei Jing and claimed by traditional scholars, and drew the following conclusions. Result & Conclusion : According to Huang Di Nei Jing tri-energizer is one of the six hollow-organs and is called hollow organs for digestion and elimination, water guffer organ, or solitary hollow organ. It is believed that tri-energizer is regarded as the existing entity based on following several different sources; it functions as the course of channels, regulates wind and link and physiological function-especially intrinsic function of upper, middle, lower internal organs. It also controls syndromes and dysfunction of an illness, the surface of the body, and the cracked surface of the skin. Finally, bold and timidity depend on the tri-energizer. Experts determined the true nature of tri-energizer types. Experts include: Yu Tuan from the Ming dynasty, Tang Jong Hai and Ye Lin from the Qing dynasty, and Zhang Xi Chun from the Zhunghua Minguo period. These experts' claims are based on shape and forms of tri-energizer. Our examinations of anatomical and physiological basis on tri-energizers showed that, in a narrow sense, tri-energizer indicates visceral and parietal peritoneum and omentum surrounding the internal organs, and in a broad sense, indicates the overall membrane wrapping around the whole internal organs including five visceral organs and six hollow organs.

Craniosynostosis is the premature fusion of calvarial sutures, resulting in deformed craniofacial appearance. Hence, for a long time, it has been considered an aesthetic disorder. Fused sutures restrict growth adjacent to the suture, but compensatory skull growth occurs to accommodate the growing brain. The primary goal for the management of this craniofacial deformity has been to release the constricted skull and reform the distorted shape of the skull vault. However, the intellectual and behavioral prognosis of affected children has also been taken into consideration since the beginning of the modern era of surgical management of craniosynostosis. A growing body of literature indicates that extensive surgery, such as the whole-vault cranioplasty approach, would result in better outcomes. In addition, the age at treatment is becoming a major concern for optimal outcome in terms of cosmetic results as well as neurodevelopment. This review will discuss major concerns regarding neurodevelopmental issues and related factors.

Unlike structures in the air, the vibration analysis of a submerged or floating structure such as offshore structures or ships is possible only when the fluid-structure interaction is understood, as the whole or part of the structure is in contact with water. Specially, the importance of the added mass is not necessary to say like the submerged vehicle, all of the hull body, is positioned in the water. This paper introduce two method to find natural frequency in consideration of fluid-structure modal coupled vibration analysis. The purpose of this study is to analyze of the vibration characteristic of submerged vehicle to obtain the anti-vibration design data, which could be used in the preliminary design stage data. Underwater pressure hull of submerged vehicle is used as the model of this study. The F.E.M model is meshed by shell and beam element. Also, considering of the inner hull weight, mass element is distributed in the direction of hull length. Numerical calculations are accomplished using the commercial B.E.M code. The characteristics of natural frequency(eigenvalues), mode shape(eigenvectors) and frequency-displacement response are analyzed. The results of this study will be used as the useful design data in preliminary anti-vibration design stage.
