<P><B>Abstract</B></P><P><B>Background:</B></P><P>Clarithromycin-containing triple regimen for eradication of <I>Helicobacter pylori</I> is no longer acceptable in Korea due to high clarithromycin resistance. Concomitant therapy or bismuth-containing quadruple therapy is recommended as an alternative regimen. A recent study in Korea has shown that modified quadruple therapy has comparable efficacy and safety to concomitant therapy as a first-line regimen. However, there has been no comparative study of modified quadruple therapy with bismuth-containing quadruple therapy. The aim of this study is to compare the efficacy and safety of modified quadruple therapy with those of bismuth-containing quadruple therapy as a first-line regimen and to present the phenotypic and genotypic antibiotic resistance profile of <I>H pylori</I>.</P><P><B>Methods:</B></P><P>This study is an open-label, multicenter, randomized controlled trial. We are recruiting subjects endoscopically diagnosed with <I>H pylori</I> infection from 2 hospitals in Korea. Subjects will be randomly allocated either to modified quadruple therapy (proton-pump inhibitor bid, amoxicillin 1 g bid, metronidazole 500 mg tid, bismuth subcitrate 300 mg qid daily) or bismuth-containing quadruple therapy (proton-pump inhibitor bid, tetracycline 500 mg qid, metronidazole 500 mg tid, bismuth subcitrate 300 mg qid daily) for 14 days. The rate of eradication success and adverse events will be checked at least 4 weeks after the treatment. Antibiotic resistance will be established using both a bacterial culture with agar dilutions and DNA sequencing of the clarithromycin resistance point mutations in the 23S rRNA gene of <I>H pylori.</I></P><P><B>Conclusion:</B></P><P>The results of this study will provide solid evidence for determining the optimal treatment regimen for first-line <I>H pylori</I> eradication in Korea.</P>

<P>Digital rectal examination (DRE) is a simple clinical method to diagnose anorectal disorders. High-resolution antorectal manometry (HRAM) based on a spatiotemporal plot is expected to promote improved diagnostic accuracy. However, there are no reports comparing the effectiveness of DRE and HRAM. The aim of our study was therefore to evaluate the diagnostic value of DRE compared with HRAM.</P>

손재현,이용화 東國大學校 1994 東國論叢 Vol.33 No.-

The aim of this research is in analyzing arch motion of rhythmic sport gymnastics scientifically. The subjects of this study are two students in each group A and B, who are at D high school in S city. I till some pictures of the gravitational center of body and movement of each subject body a with 16mm video camera from shich I analyzed their motions: not only in angular displacement, angular velocity, and angular acceleration of 'Knee joint', but also, in those of 'Hip joint', including 7other parts of their bodies. 1. It was shown that the gravitational center of body in phase 3 and 4 should be done many times so that they could perform 'Arch motion' much higher and more precisely. 2. There should be a long pause at the highest position of tiptoes for them in order to perform sharp and beautiful Arch motion. 3. To obtain the No.2 effect, it could be extremely influenced by angular accelration in phase 4 of Knee joints. 4. It was shown, however, that the above three elements of Hip joint movement did not much affect on the performance of Arch motion. 5. As a result of analysion 7 phase of body motion, I observed that when movement of each joint in phase and 4, but not phase 1, 2 and 5, was performed enthusiastically and accurately, the such movements could be perfect. 6. Accurate movement of each joint are essential in arch movements, which should be followd by flexibility of shoulders, upper body, and the lower part of the body, especially by the power of kicking up the right leg in phase 3, and what is more important, sufficient practice should be done in maintaining the balance between the supporting right leg and the left leg kicked up.

Soh, Sarah,Shim, Jae-Kwang,Song, Jong-Wook,Kim, Keung-Nyun,Noh, Hyun-Young,Kwak, Young-Lan Wolters Kluwer Health, Inc. All rights reserved 2017 Journal of neurosurgical anesthesiology Vol.29 No.4

<P>Background: Perioperative cerebral hypoperfusion/ischemia is a major inciting factor of postoperative delirium, which is coupled with adverse outcome in elderly patients. Cerebral oximetry enables non-invasive assessment of the regional cerebral oxygen saturation (rSO(2)). This study aimed to investigate whether perioperative rSO(2) variations were linked to delirium in elderly patients after spinal surgery. Materials and Methods: Postoperative delirium was assessed for 48 hours postsurgery in 109 patients aged over 60 years without a prior history of cerebrovascular or psychiatric diseases by the Confusion Assessment Method for the intensive care unit and the intensive care delirium screening checklist. The rSO(2) values immediately before and throughout surgery were acquired. The preoperative cognitive functions, patient characteristics, and perioperative data were recorded. Results: During the 48-h postoperative period, 9 patients (8%) exhibited delirium. The patients with delirium showed similar perioperative rSO(2) values as those without, in terms of the median lowest rSO(2) values (55% vs. 56%; P = 0.876) and incidence (22%, both) and duration of decline of rSO(2) < 80% of the baseline values. The serially assessed hemodynamic variables, hematocrit levels, and blood gas analysis variables were also similar between the groups, except for the number of hypotensive events per patient, which was higher in the patients with delirium than in those without (4, interquartile range [IQR] 3 to 6 vs. 2, IQR: 1 to 3; P = 0.014). Conclusions: The degree and duration of decrease of the perioperative rSO(2) measurements were not associated with delirium in elderly patients after spinal surgery.</P>

소현,임대재,김영채 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.1

단량체인 hexafluropropene(C_3F_6) 기체를 플라즈마 증합하여 구리표면에 증착된 불소화합물이 표면 소수성 성향의 관점에서 조사되었다. 표면 소수성이 최대가 되는 조건을 찾기 위해 플라즈마 변수를 변화시켰으며 플라즈마 출력과 압력 증가에 따라 증착속도는 최대 60[㎍ cm^-2min^-1]를 나타냈다. 100W, 1torr, 10min의 공정변수에서 표면 자유에너지가 8.8[dyne cm^-1]로 물과의 접촉각이 127.75℃ 소수성 표면을 확인하였다. 플라즈마 증착된 표면은 CF, CF_2등의 불화탄소 기능기가 표면에 도포 되었으며 C/F 비가 2이하를 나타내었다. 구리표면에 형성된 불소화합물은 1㎛이하의 두께로 얇고 균일한 형태를 지니고 있으며 표면 조도의 증가가 접촉각을 더욱 상승시켜 구리표면이 합성고분자인 PTFE(108˚)보다 소수성이 향상되었다. Fluorocarbon, which was deposited on copper surface by plasma polymerization with monimer C_3F_6, was investigated from the point the hydrophobicity. Plasma parameterswere changed to find the maximum conditions of the surface hydrophobicity. Rate of deposition with increasing plasma power and pressure showed the value of 60[㎍ cm^-2min^-1]. It was found that the surface energy was 8.8[dyne cm^-1] and contact angel with water was 127.75℃ at the optimum conditions, 100W, 1torr, 10min. The surface with plasma deposition was coated fluorocarbon groups such as CF, CF_2 and C/F atomic ratio showed the value of less than 2. Deposited fluorocarbon indicated thin and homogeneous film with the thickness of 1㎛. Contact angels of plasma deposited Cu surface showed more hydrophobic than that of synthesis polymer PTFE(108˚).
