The present study aims to explore the effects of applying spheroid-combined stimulating therapy on body composition. For this aim. 20 persons were selected as subjects and 10 of them each were assigned to the experimental group and control group, respectively. The experimental group was applied a 12-week combined stimulating therapy and changes in physical constitution of the members were measured before application and 4, 8 and 12 weeks after application. From the study, following conclusions could be drawn: First, body weights of the experimental group decreased from 59.9kgs before application of the spheroid-combined stimulating therapy to 57.2kgs 12 weeks after application, no significant but 4.51% change. Second, body fats of the experimental group changed from 18.8kgs before application to 16.4kgs 12 weeks after application, no significant but 12.77% reduction. Third, % fats of the experimental group decreased from 31.2% before application to 28.6% 12 weeks after application, no significant change but 8.33% reduction. Fourth, body mass index(BMI) of the experimental group decreased from 23.23 kg/㎡ before application of the therapy to 21.43kg/㎡ after application, no significant but 8.03% reduction. As seen above, the 12-week application of the spheroid-combined stimulating therapy produced no significant changes in physical constitution as physical exercise did, but improved physical constitution by reducing certain amount of boy weight, body fat, % fat and BMI. In order to detect more positive and significant changes in physical constitutions, continued studies and clinical experiments should be performed to more diverse subjects using technically reinforced equipment for spheroid-combined stimulating therapy.

다큐멘터리 재현양식 연구 : <워낭소리>와 <택시 블루스>를 중심으로

민환기,이유빈 영상예술학회 2009 영상예술연구 Vol.15 No.-

다큐멘터리가 묘사하고자하는 사람이나 사건은 현실에 실제로 존재한다. 픽션 영화의 인물이나 장소가 허구의, 만들어진 존재임에 반하여 다큐멘터리가 묘사하는 대상은 다큐멘터리의 묘사와는 상관없이, 또는 다큐멘터리가 그 존재를 묘사하지 않았을 때에도 존재한다. 하지만 현실에 존재하는 대상을 재현하기 위해서는 인공적인 장치에 의존해야 한다. 그 장치는 재현해야 하는 현실의 속성과는 다른 종류의 미학적인 장치이다. 그렇기 때문에 미학적인 장치를 통한 재현은 현실을 지시하면서도 왜곡하거나 변화시킬 가능성을 처음부터 안고 출발한다. 본 글은 <택시 블루스>와 <워낭소리>의 재현양식의 분석을 목표로 한다. 두 영화 모두 혼합된 다큐멘터리 양식을 사용하면서 다큐멘터리가 가진 표현양식의 한계를 넘어서려고 시도했다. 그 결과로 <택시 블루스>는 픽션이냐 아니냐 하는 논란에 휩싸였고 <워낭소리>는 다큐멘터리로서는 드물게 300만 관객을 동원하는 대중적 성공을 거두었다. 물론 재현양식이 그 결과를 모두 설명할 수 있는 것은 아니겠지만 두 영화가 가지고 있는 장점과 단점은 많은 부분 특정한 재현양식의 차용과 그것의 변형에서 비롯된다. 빌 니콜스(Bill Nichols)의 재현양식의 구분을 따라서, 두 영화가 차용한 지배적인 재현양식과 그것의 변형이 어떤 목적을 위해서 어떻게 사용되었고 그것의 효과가 무엇인지를 그리고 그러한 재현양식이 현실과 맺는 관계를 분석한다. A documentary film describes people or events being in the world. People or events in the documentary have existed without such a description unlike people or events in the fiction film. To represent things in the world depends on artificial devices different from things in their nature. Because of it, things described are always both an indication and a distortion of things in the world. I try to analyse Taxi Blues and An old partner in terms of representational mode. Both films try to negotiate confliction between the real and its representation with mixed representational mode. it produced a huge success of An old partner in box office and critical debates on Taxi Blues. Although it is not sufficient to explain all the issues related to both films by analysis of their representational mode, I believe it can hint its success and failure of each film regarding such a negotiation and enrich discourses on documentary film-making in Korean soil. With Bill nichols's categorization, I will analyse both films' representational mode, and its effect on the real and its representation, and the audience.

이혁,김유광,김경빈 大韓神經精神醫學會 1991 신경정신의학 Vol.30 No.1

This study was attempted to clarify sociopsychiatric characteristics according to the class of psychoactive substances which were classified into 8 groups such and methamphetamin, cocaine, inhalants(bond/gas), dextromethorphan(Romilar), sedatives marijuana, analgesics and etc. The data of the study were collected from 134 psychoactive substance abusers(89men, 45women), who had admitted to SNMH during past 5 years. The results were as follows ; 1) The mean age of patients was 26.5±9.6 years and according to the class of psychoactive substance, inhalant and dextromethorphan abusers were significantly younger than sedatives and analgesics abusers(P〈0.01). 2) 43.1% of patients were grown up in broken family until puberty and 27.9% of married patients showed unstable marital state such as a divorce or seperation. 3) 41.4% of patients had past history of delinquent behavior and especially, inhalants and dextromethorphan abusers had more past history of delinquent behavior than sedatives and analgesics abusers(P〈0.01). 4) The main motive of mitiation of psychoactive substance was peer pressure, relief of psysical symptoms, curiosity in that order. 75% of inhalants abusers were itiated by peer pressure, but most of sedatives and analygesics abusers used it for the purpose of relieving of physical symptoms, and methamphetamine abusers used it mainly due to peer pressure or for the purpose of increasing sexual plesure(P〈0.01). 5) 57.5% of patients reported the experience of unwanted response such as unpleasant hallucinatory state, loss of control, and psychotic state after use of psychoactive substances. Especially the unwanted respose was reported more frequently in methamphetamin and inhalants abusers. 6) 38.5% of patients abused more than two classes of psychoactive substances, and their significant combination types were not found but inhalant-dextromethorphan, analygesics-sedatives and methamphetamine-marijuana combination types were relatively common.

The purpose of this study was to compare the diagnostic accuracy of positron emission tomography/computed tomography (PET/CT), abdomino-pelvic computed tomography (CT), and pelvic magnetic resonance imaging (MRI) for detection of early stage ovarian cancer. Medical record of 140 women who underwent PET/CT scanning with suspected early stage ovarian cancer (stage 1-2) from July 2005 to February 2012 was retrospectively reviewed. Preoperative CT, MRI, and PET/CT findings were compared with histopathologic results obtained from the surgery. The accuracy of each modality in detection of malignancy was evaluated by computing the relevant areas under a receiver operating characteristics(ROC) curve and comparisons of the area under the curve (AUC) according to the modality (MedCalc® version 9.6.3.0, Broekstraat 52, 9030 Mariakerke, Belgium). Histopathology showed 7 cases of benign tumors, 23 cases of borderline tumors, and malignant tumors in 110 cases. In detecting malignant lesions in the ovaries and the adnexa, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of PET/CT were higher than the corresponding values of CT or MRI. In discriminating between cases of benign/borderline and malignant, the accuracy of PET/CT (0.760) trended higher than that of CT or MRI (0.585). PET/CT is more accurate than abdomino-pelvic CT or pelvic MRI in diagnosis of early stage ovarian cancer and in differentiating between cases of benign/borderline and malignant ovarian tumors.

<P><B>Abstract</B></P> <P>By using electricity from renewable sources, high-temperature solid oxide co-electrolysis cells (SOCs) can perform advantageous conversion of H<SUB>2</SUB>O/CO<SUB>2</SUB> to high-value syngas. In this work, we investigated the performance of tubular solid oxide co-electrolysis cells for the production of syngas by electrochemical conversion of H<SUB>2</SUB>O/CO<SUB>2</SUB>. The tubular solid-oxide electrolysis cells comprise Ni-yttria stabilized zirconia (Ni-YSZ) based fuel-electrode supported cells, a yttria or scandia-stabilized zirconia (YSZ and ScSZ) electrolyte, and a composite air-electrode of (La<SUB>0.85</SUB>Sr<SUB>0.15</SUB>)<SUB>0.9</SUB>MnO<SUB>3</SUB> (LSM) and La<SUB>0.6</SUB>Sr<SUB>0.4</SUB>Co<SUB>0.2</SUB>Fe<SUB>0.8</SUB>O<SUB>3</SUB> (LSCF). The electrochemical performance of the tubular SOCs for various operating conditions was analyzed using I-V curves, EIS analysis, and gas chromatography. From the results, we confirm the correlation between the operating conditions and the electrochemical performance of the co-electrolysis process in the tubular SOCs. Furthermore, we found that the syngas yield of the ScSZ electrolyte-based SOC cell was better than that of the YSZ electrolyte-based SOC. The results show that using a tubular SOC offered highly efficient conversion of H<SUB>2</SUB>O/CO<SUB>2</SUB>, with high yield and good-quality syngas.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Effect of temperature, inlet gas composition on syngas yield investigated. </LI> <LI> In coelectrolysis, ScSZ electrolyte based SOC performs better than YSZ based SOC. </LI> <LI> Higher amount of CO<SUB>2</SUB> in the feed gas produces more CO in syngas. </LI> <LI> It is possible to achieve high syngas yield through optimized the conditions. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

First Report on Bacterial Heart Rot of Garlic Caused by Pseudomonas fluorescens in China

Bin Li,Rong Rong Yu,Shan Hong Yu,Wen Qiu,Yuan Fang,Guan Lin Xie 한국식물병리학회 2009 Plant Pathology Journal Vol.25 No.1

An unreported disease of garlic was observed in commercial fields in Jiangsu province, China. The symptoms started as water soaked lesions at the base of the leaves. Later, water-soaked areas developed on stems and spread to the internal tissues, followed by yellowing and necrosis along leaf edges and soft rot of the stems. The causal organism isolated from symptomatic plants was identified as Pseudomonas fluorescens based on its biochemical and physiological characteristics and confirmed by the cellular fatty acid composition and Biolog data as well as 16S rRNA gene sequence analysis. The bacterial isolates caused similar symptoms when inoculated onto garlic plants. In addition, leek and shallot were susceptible to the P. fluorescens pathogen. However, the P. fluorescens pathogen failed to cause any symptoms when it was inoculated onto 15 other plants. This is the first report of a bacterial disease of garlic caused by P. fluorescens in China.

Biophysical effect of lipid modification at palmitoylation site on the structure of Caveolin 3

Yu-Bin Ma,Dong-Hoon Kang,김명규,김지훈 한국자기공명학회 2019 Journal of the Korean Magnetic Resonance Society Vol.23 No.3

Caveolae are small plasma membrane invaginations that play many roles in signal transduction, endocytosis, mechanoprotection, lipid metabolism. The most important protein in caveolae is the integral membrane protein, caveolin, which is divided into three families such as caveolin 1, caveolin 2, and caveolin 3. Caveolin 1 and 3 are known to incorporate palmitate through linkage to three cysteine residues. Regulation of the protein palmitoylation cycle is important for the cellular processes such as intracellular localization of the target protein, membrane association, conformation, protein-protein interaction, and activity. However, the detailed aspect of individual palmitoylation has not been studied. In the present work, the role of each lipid modification at three cysteines was studied by NMR. Our results suggest that each lipid modification at the natively palmitoylation site has its own roles. For example, lipidations to C106 and C129 are play a role in structural stabilization, however, interestingly, lipid modification to C116 interrupts the structural stabilization.
