To compare the airway resistance effects of two heat and moisture exchangers(HME) during short-term intraoperative volume controlled mechanical ventilation. Following a randomized order, the patients were ventilated during 3hrs with two HMEs(Pall conserve and Humi-vent filter). In each patient and for each 5 min, lhr, 2hrs and 3 hrs period, body temperature and airway resistance were measured. The hydrophobic HME (Pall conserve) had a good theraml conservation capacity, but increase airway resistance(11.7±2.9cm H_2O/1/s to 15 4±3.4 after lhr, to 17.3±2.5 after 2hrs, to 17.5±3.3cm H_2O/l/s after 3hrs). The hygroscopic filter(Humi-vent filter) had a good thermal conservation capacity, and less increase airway restance than Pall conserve(13.0±2.3 to 15. 4±3.4. after 1hr, 15.9±2.5 after 2hrs, 15.0±3.3 cmH2O/I/s after 3hrs). The hygroscopic HME had a thermal and humidification capacity and less increase the airway resistance.

In the ship structure, the stress concentration is to be occured at the corner of hatch opening under static and dynamic loading conditions. Recently, the ship structure design based on the fatigue strength analysis is increasingly demanded. Therefor, we analyzed the main deck hatch corner which was representative discontinuty of ship structure with ANSYS. According to the results, the stress concentration factor is lied from 1.68 to 6.41.

We performed a variety of lymphocyte stimulation tests, delayed hypersensitivity skin tests, and enumeration of several lymphocyte subpopulations in 21 patients with gastric cancer who did not receive any form of anticancer therapy, and in 20 healthy controls. The gastric cancer patients had significantly decreased number and total score of positive reactions in delayed hypersensitivity skin tests compared with the healthy controls. The percent of CD_(4) positive lymphocytes in the gastric cancer patients was significantly decreased compared to the normal control subjects, but it had no correlation with the total score of delayed cutaneous hypersensitivity reactions. The ratio of helper to suppressor cells was lower in the cancer group. The uptake of 3H-thymidine was markedly depressed in cancer patients when stimulated with various mitogens. There was little correlation between any of the stimulation tests and any of the lymphocyte subpopulation proportions to delayed hypersensitivity cutaneous reactions. Optimal proliferative response was found in lymphocytes stimulated with 10 micrograms of concanavalin-A and 10 microgram of phytohemagglutinin. Advanced stage patients had greatly depressed delayed hypersensitivity skin reactions and proliferative responses to mitogens compared with localized diseases. These results suggest that gastric cancer patients have depressed cellular immune functions, which mainly result from the decreased helper cells and defects in functional proliferative response to mitogens. Interleukin-2 and interferon-gamma restored the in vitro proliferative response of lymphocyte in patients with gastric cancer.

Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

Objective : The aim of this study was to review systemically clinical trials on the effectiveness and safety of herbal medicines in the treatment of osteoarthritis. Methods : Computerized literature searches were carried out on seven electronic databases, and hand-searching on some chinese medical journals in library of Kyung Hee Medical Center. Trial data were extracted in a standardized, predefined manner and assessed independently. Results : 1. Thirty reports of clinical trials and two reports of meta-analyses concerning herbal medicine were collected and reviewed Among these reports three medical herbs were applied as topical medicine and others as internal medicine. 2. The western studies established NSAIDs or placebo as their control group. Five chinese reports established formulated herb pill(Ruanshnagshenjin pill) as their control group and Six did not establish a control group at all. 3. ACR was the most highly used diagnostic criteria in the western studies while the Chinese used their official criteria established by their government or the criteria of their text books. 4. 20 reports chose the Lequesne functional index, SHAQ, WOMAC OA index, AIMS, and their own unique scoring system as the criteria of analysing the effect. Others chose clinical symptoms, articular functions, and lab finding as their criteria. 5. 7 single herbs and 19 formulated herbs were studied. Among the formulated herbs, Achyranthes japonica was studied in 10 of the studies and Angelica gigantis Radix in 8, making them the most often studied herbs among the studies.

<B>Graphic Abstract</B> <P>The cover shows an image of fully rollable transparent nanogenerators synthesized using chemical vapor deposition grown large-scale graphene sheets as transparent electrodes and piezoelectric ZnO nanorod arrays. Sang-Woo Kim, Jae-Young Choi, and co-workers report on p. 2187 the electrical and structural stability of the nanogenerators, with excellent charge scavenging performance under external mechanical loads such as bending and rolling. This study shows that graphene-based nanogenerators are very promising for self-powered rollable transparent device applications. <img src='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content.gif' alt='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content'> </P>

식혈세포성 림프조직구증은 발열, 비장종대, 혈구감소, 식혈 현상을 특징으로 하는 흔하지 않은 질환이다. 식혈세포성 림프조직구증은 주로 감염성 질환이나 악성 질환과 연관이 되어 있다. 바이러스와 연관된 식혈세포성 림프조직구증은 주로 헤르페스 바이러스균, 특히 거대 세포바이러스, 엡스타인-바 바이러스와 연관되어 있다. 한탄바이러스와 연관된 식혈세포성 림프조직구증은 매우 드물어, 현재까지 수개의 증례만 보고되었다. 이에 저자들은 식혈세포성 림프조직구증의 특징인 발열, 비장종대, 혈구감소, 골수 검사에서 식혈 현상을 보이면서 혈청학적 검사에서 신증후군 출혈열로 진단된 환자에서 보존적인 치료로 회복된 증례를 경험하였기에 보고하는 바이다.
