김주옥,안원전,박종훈,노흥규,박종우 충남대학교 의과대학 지역사회의학연구소 1987 충남의대잡지 Vol.14 No.1
Total 20 cases of infectious diseases were treated with Cefotetan at the Dept. of internal medicine, Chung Nam National University Hospital, Dae Jeon, Korea, from January 1985 to April 1985. Among 20 cases, 6 were the patients with acute pyelonephritis, 7 were pneumonia, 2 were acute cholecystitis, 2 were chronic bronchitis, 2 were cellulitis and 1 was lung abscess. The response was good in 16 cases, and poor in 4 cases. The laboratory tests were normal except I which was reversible. (mild elevation of SGOT and SGPT) The side effects were noted in 2 cases, such as skin eruption and drug fever, which were improved with supportive care. Cefotetan was thought to be useful against acute bacterial infections of respiratory, urinary, biliary tracts and cutaneous tissue.

이지현,이기주,윤성호,부귀범,손현화,박유환,정춘해,김진호,정원영 조선대학교 부설 의학연구소 1998 The Medical Journal of Chosun University Vol.23 No.2
Multiple sclerosis and lupus erythematosus are chronic, potentially disabling diseases of unknown cause. It is a rare occasion that the finding of both diseases occurs in one patient. Because both diseases may affect the central nervous system, it may be difficult at times to differentiate symptoms of lupus erythematosus from those of multiple sclerosis. As far as we know, there was no case report of SLE in multilple sclerosis in Korea. We report a case of multiple sclerosis accompanied by SLE.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

In this study, we propose a small high voltage power supply, which uses a half-bridge ZCS resonant and Cockroft-Walton circuit as its ESP (Electrostatic Precipitator). This power supply transfers energy from the ZCS resonant inverter to the step-up transformer. The transformer secondary is then applied to the Cockroft-Walton circuit for generating high voltage as a discharging source of electrodes. It is highly efficient because its amount of switching losses are reduced by virtue of the current resonant half-bridge inverter, and also due to the small size, low parasitic capacitance in the transformer stage owing to the low number of winding turns of the step up transformer secondary combined with the Cockroft-Walton circuit. Using this power supply, experiments have been carried out as a function of the switching frequency and duty ratio in order to investigate the smoke removal characteristics. From these results, the best operational condition is obtained at the switching frequency of 9 kHz and the duty ratio of 50% in this ESP.

<P>The diamondback moth, Plutella xylostella (L.), is a major pest responsible for destroying cabbage and other Brassica vegetable crops. A diamondback moth-resistant cabbage line was studied by comparing its metabolite profiles with those of a susceptible cabbage. Fourier transform infrared spectroscopy analysis revealed that carbohydrates, aromatic compounds, and amides were the major factors that distinguished the resistant and susceptible genotypes. Gas chromatography–time-of-flight mass spectrometry profiled 46 metabolites, including 19 amino acids, 15 organic acids, 8 sugars, 3 sugar alcohols, and 1 amine in two genotypes and F<SUB>1</SUB> hybrid cabbages. The levels of glycolic acid, quinic acid, inositol, fumaric acid, glyceric acid, trehalose, shikimic acid, and aspartic acid were found to be very significantly different between the resistant and susceptible genotypes with a <I>P</I> value of <0.0001. These results will provide a foundation for further studies on diamondback moth resistance in cabbage breeding and for the development of other herbivore-resistant crops.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jafcau/2013/jafcau.2013.61.issue-46/jf403441t/production/images/medium/jf-2013-03441t_0006.gif'></P>
Systematic Lymphadenectomy for Survival in Epithelial Ovarian Cancer : A Meta-Analysis
Kim, Hee Seung,Ju, Woong,Jee, Byung Chul,Kim, Yong Beom,Park, Noh Hyun,Song, Yong Sang,Kim, Seung Cheol,Kang, Soon-Beom,Kim, Jae Weon BMJ 2010 International journal of gynecological cancer Vol.20 No.4
<P>BACKGROUND: The role of systematic lymphadenectomy (SL) remains unclear for improving overall survival (OS) in epithelial ovarian cancer (EOC). To evaluate the role of SL in EOC, we performed a meta-analysis for comparing the efficacy for OS between SL and unsystematic lymphadenectomy (USL). METHODS: After the extensive literature search between January 1995 and December 2008, we analyzed 9 studies (2 randomized controlled trials [RCTs] and 7 observational studies) with 21,919 patients with EOC who underwent staging laparotomy including SL or USL. RESULTS: Although SL was a favorable factor for OS compared with USL (hazard ratio [HR], 0.72; 95% confidence interval [CI], 0.68-0.76), the efficacy of SL on increased OS could not be determined in all-stage and early-stage EOC owing to the lack of RCTs and the deviation of weight by large-scale observational studies, whereas SL improved OS in advanced-stage EOC (HR, 0.70; 95% CI, 0.67-0.75). Moreover, SL increased OS in patients with all-stage disease who underwent optimal debulking surgery (HR, 0.84; 95% CI, 0.69-0.99), whereas it could not improve OS statistically in early-stage and advanced-stage diseases. However, SL showed increased OS with marginal significance in advanced-stage EOC patients treated with optimal debulking surgery (HR, 0.82; 95% CI, 0.66-1.02). CONCLUSIONS: These findings suggest the possibility that SL can improve OS in advanced-stage EOC. However, the efficacy of SL on OS is still unknown because of the lack of RCTs, which requires more relevant studies for investigating the role of SL in EOC.</P>

Continuous fiber-reinforced ceramic matrix composites (CFCCs) have a complex distribution of porosity, consisting of interfiber micro pores and interbundle/interply macro pores. Owing to the complex geometry of the pores and fiber architecture, it is difficult to obtain representative microstructural features throughout the specimen volume with conventional, destructive ceramographic approaches. In this study, we introduce X-ray computed microtomography (X-ray ${\mu}CT$) to nondestructively analyze the microstructures of disk shaped and tubular $SiC_f$/SiC composites fabricated by the chemical vapor infiltration (CVI) method. The disk specimen made by stacking plain-woven SiC fabrics exhibited periodic, large fluctuation of porosity in the stacking direction but much less variation of porosity perpendicular to the fabric planes. The X-ray ${\mu}CT$ evaluation of the microstructure was also effectively utilized to improve the fabrication process of the triple-layered tubular SiC composite.
