  • 후지 전체의 정렬 평가에 필요한 정렬각도의 정상치를 측정하기 위하여, 정형외과적 질환이 없고 육안 또는 방사선 검사에서 각기형이 없는 것으로 판단되는 소형견 사체(말티즈, 푸들, 시추, 요크셔테리어) 의 후지 60개를 사용하였다. 각각의 후지를 완전히 신장시켜 전면 방사선 사진을 촬영하였으며, 이를 통해 기계적경골대퇴골각도(mechanical tibiofemoral angle, mTFA), 기계적중족경골각도 (mechanical metatarsotibial angle (mMTTA) 기계축-대퇴각도(mechanical axis-femur angle (MAFA), 기계축-중족각도(mechanical axis-metatarsus angle (MAMTA)을 측정하였으며, 무릎관절과 뒷발목관절의 기계축변위(mechanical axis deviation, SMAD or TMAD)의 평균값과 95% 신뢰구간 값을 전체 그리고 품종별로 측정하였다. 소형견 전체의 mTFA, MTTA, MAFA, MAMTA의 95% 신뢰구간 값은 각각 $5.7-7.4^{\circ}$, $-2.2--0.8^{\circ}$, $3.5-4.5^{\circ}$, $1.0-2.0^{\circ}$였으며, SMAD와 TMAD는 2.1-2.7%, 0.5-1.0%로 측정되었다. 본 연구에서 제시한 소형견의 후지정렬 측정법과 정상치는 소형견종의 후지 각기형의 진단 및 평가, 수술 계획에 있어 유용하게 사용될 수 있을 것이라 사료된다.

  • Effect of chemically modified precursor solution on YBCO coated conductor prepared by MOD-TFA method was investigated. YBCO thin films were deposited on (l00)-oriented single crystalline LaAlO$_3$ substrates by conventional MOD-TFA process. The microstructures of YBCO thin films contain maze-like patterns. The origin of this microstructure was delineated by compositional inhomogeneity during the pyrolysis process and it was shown that addition of diethanolamine (DEA) improve the microstructure of grown YBCO films. In addition, it was demonstrated that the chemical modification of precursor solution makes no harmful effect on biaxial texture of YBCO thin films.

  • A sensitive and selective reversed-phase LC-ESI-MS method to quantitate pseudoephedrine in human plasma was developed and validated. Phenacetin was used as an internal standard. Samples were prepared simply by acetonitrile precipitation without an evaporation step. Chromatographic separation was achieved on a XTerra MS C18 column ($150{times}2.1$ mm I.D.. 3.5 $\mu\textrm{m}$ particles). using gradient elution with 0.5% (v/v) trifluoroacetic acid (TFA) in water and 0.5% (v/v) TFA in methanol at a flow-rate of 0.1 ml/min.

  • The purpose of this study was to examine the association between fatty acid intake and dyslipidemia in Korean adults, using data from the Korean National Health and Nutrition Examination Survey (KNHANES)I, II, III, and IV. After excluding subjects who had missing data for the dietary intakes, anthropometric measurments and laboratory tests, a total of 15,804 subjects aged 20~64 y (6,838 men and 8,966 women) from KNHANES 1998~2007 were included. All data were analyzed using SPSS Statistics software (version 18.0). Associations between fatty acid intakes and dyslipidemia were analyzed by logistic regression analysis after adjusting for age, BMI, energy intake, marital status, job, education level, alcohol intake, and smoking status. Fatty acid intakes were significantly higher in men than in women. The risk of hypertriglyceridemia was significantly and negatively associated with intakes of TFA, SFA, MUFA, PUFA, EPA, DHA, n-3 PUFA, and n-6 PUFA in both men and women. The risk of hypercholesterolemia was not significantly associated with any fatty acid intakes in either sex. The risk of high LDL cholesterolaemia was significantly and positively associated with intakes of TFA, MUFA, PUFA, LNA, n-3 PUFA, and n-6 PUFA in men however, there was no significant association with any fatty acids in women. The risk of low HDL cholesterolaemia was significantly and positively associated with intakes of TFA, MUFA, PUFA, LNA, n-3 PUFA, and n-6 PUFA in men, and was significantly and negatively associated with intakes of MUFA, PUFA, LNA, and n-3 PUFA in women. These results show that dyslipidemia is significantly associated with individual intake of fatty acids, suggesting that fatty acid type may be related to the risk of dyslipidemia.
