A Study on the Electrical Physical Properties of Organic Thin Films for Manufacture in Power Device
Song, Jin-Won,Lee, Kyung-Sup The Korean Institute of Electrical and Electronic 2005 Transactions on Electrical and Electronic Material Vol.6 No.1
Monolayers of lipids on a water surface have attracted much interest as models of biological membranes, but also as precursors of multilayer systems promising many technical applications. Until now, many methodologies have been developed in order to gain a better understanding of the relationship between the structure and function of the monolayers. Maxwell displacement current (MDC) measurement has been employed to study the dielectric property of Langmuirfilms. MDC flowing across monolayers is analyzed using a rod-like molecular model. A linear relationship between the monolayer compression speed a and the molecular area Am. Compression speed a was about 30, 40, and 50 mm/min. Langmuir-Blodgett(LB) layers of Arachidic acid deposited by LB method were deposited onto slide glass as Y-type film. The structure of manufactured device is Aul Arachidic acid! AI, the number of accumulated layers are $9{\sim}21$. Also, we then examined of the Metal-Insulator-Metal(MIM) device by means of I-V. The I-V characteristics of the device are measured from -3 to+3 V. The insulation property of a thin film is better as the distance between electrodes is larger.
Performance of Confirmatory Interferon-γ Release Assays in School TB Outbreaks
Song, Seunghwan,Jeon, Doosoo,Kim, Jong Won,Kim, Yeong Dae,Kim, Sang-Pil,Cho, Jeong Su,Lee, Seung Eun,Cho, Woo Hyun,Park, Hye-Kyung,Kim, Yun Seong,Lee, Min Ki,Lee, Jun Ho Elsevier 2012 Chest Vol.141 No.4
<P>Interferon-γ release assays (IGRAs) have been incorporated into several national guidelines for latent TB infection (LTBI) diagnosis. However, their optimal application is still controversial and evolving. The aim of this study is to evaluate the performance of confirmatory IGRAs in addition to tuberculin skin tests (TSTs) in high school students with TST-positive (TST+) results who have had contact with another student who had TB (referred to in this article as 'contacts') in TB outbreaks in a high BCG-vaccinated population.</P>

Objective: This study aimed to investigate the difference in micronutrient levels between oral feeding and enteralfeeding in chronic stroke patients to assess the risks of enteral feeding. Methods: Patients with chronic stroke who were admitted to the Department of Rehabilitation Medicine betweenJanuary 2011 and June 2012 were enrolled. The serum concentrations of iron, copper, zinc, folate, and vitamin B12,as well as the absolute CD4 and CD8 lymphocyte counts, were assessed. Results: Of the 73 patients enrolled in this study, 50 were fed orally, while the other 23 were fed through a percutaneousendoscopic gastrostomy (PEG) or nasogastric (NG) tube. The serum concentrations of vitamin B12 and folatewere significantly higher in the enteral feeding group than in the oral feeding group. However, the serum concentrationof zinc was significantly lower in the enteral feeding group. Conclusion: There is little difference between enteral feeding and oral feeding in terms of micronutrient provisionexcept that the serum concentration of zinc in the enteral feeding group was significantly lower than that in the oralfeeding group. Clinicians should recognize that chronic stroke patients who require tube feeding have a risk ofmicronutrient deficiency. Early detection of malnutrition and micronutrient deficiency is important for providing thenecessary nutrients.

N/A Background: Several studies suggested that T-wave normalization (TWN) in exercise ECG indicates the presence of viable myocardium. But the clinical implication of this phenomenon in patients with acute myocardial infarction who received proper revascularization therapy was not determined. Precisely the aim of this study was to investigate the relationship between TWN in exercise ECG and myocardial functional recovery after acute myocardial infarction. Methods: We studied 30 acute myocardial infarction patients with negative T waves in infarct related electrocardiographic leads and who had received successful revascularization therapy. Exercise ECG was performed 10∼14days after infarct onset using Naughton protocol. Patients were divided into 2 groups according to presence (group I; n=14) or not (group II; n=16) of TWN in exercise ECG. Exercise parameters and coronary angiographic findings were compared between groups. Baseline and follow-up (mean 11 months) regional and global left ventricular function was analyzed by echocardiography. Results: Exercise parameters were similar between groups. There was no difference in baseline ejection fraction and wall motion score between group I and II (EF; 56±12% vs 52±11%, p=ns. WMS; 21±3 vs 23±4, p=ns) and it was improved at the tenth month by similar magnitude (group I/group II, EF % change = 12±12% vs 7±6%, p=ns, WMS % change=6±6% vs 7±5%, p=ns). The finding of no relation between TWN and functional recovery was observed also when the patients were analysed according to infarct location and presence or absence of Q-waves. Conclusion: As the exercise-induced TWN in patients with acute myocardial infarction was not related with better functional recovery of dysfunctional regional wall motion and ejection fraction, TWN does not appear to be an indicator of myocardial viability.
