  • 목적 : 골밀도검사의 중요한 부분을 차지하고 있는 검사장비 및 검사자의 정밀도와 정확도는 환경에 따라 차이가 있기 때문에 질 관리가 체계적으로 이루어져야 한다. 골밀도 검사장비의 노화 및 잦은 고장에 의하여 장비의 교체 및 추가 구입으로 인하여, 추적검사를 하는 환자들의 호환성에 문제가 있다. 따라서 장비 교체 및 증설 후 동일한 장비처럼 호환하여 시용해도 환자의 임상적인 골밀도 변화를 정확하고 정밀하게 반영할수 있는지 알아보고자 한다. 재료 및 방법 : 장비 정밀도는 GE Lunar Prodigy Advance 2 대의 장비 (P1, P2)와 HOLOGIC Spine Phantom(HSP)을 이용하여 각 장비에서 20 번씩 스캔하여 팬텀을 이용한 정밀도 데이터를 획득하였고 (Group 1), 여성 120명 (평균나이 48.78, $20{\sim}60$세)을 대상으로 각 장비에서 15명씩, 같은 환자가 두 번 촬영을 하여 각 검사자의 정밀도를 측정했다(Group 2), 또한 검사자의 정밀도는 팬텀(ASP)을 이용하여 매일 아침마다 질 관리 시행후 얻은은 데이터를 기준으로, 각각의 장비에서 HSP를 이용하여 각 장비에서 20번씩 스캔 후 데�歷� 획득하여 검사자정밀도 및교차 보정 데이터를 산출하였고(Group 3), 여성 120명(평균나이 48.78, $20{\sim}60$세)의 동일 환자를 대상으로 한 장비에서 한 번씩 교차로 측정하여 검사자 정밀도 및 교차보정 데이터를 산추라였다(Group 4). 결과 : Daily Q.C Data는 $0.996\;g/cm^2$, 변동계수(%CV) 0.08로 안정된 장비로서 Group 1에서 Mean${\pm}$SD 및 %CV값은 ALP(P1: $1.064{\pm}0.002\;g/cm^2$, $%CV=0.190\;g/cm^2$, P2: $1.061{\pm}0.003\;g/cm^2$, %CV=0.192). Group 2에서 Mean${\pm}$SD 및 %CV값은 P1: $1.187{\pm}0.002\;g/cm^2$, $%CV=0.164\;g/cm^2$, P2: $1.198{\pm}0.002\;g/cm^2$, %CV=0.163, Group 3에서의 Mean${\pm}$2SD 및 %CV는 P1 - (spine: $0.001{\pm}0.03\;g/cm^2$, %CV=0.94, Femur: $0.001{\pm}0.019\;g/cm^2$, %CV=0.96), P2 - (spine: $0.002{\pm}0.018\;g/cm^2$, %CV=0.55, Femur: $0.001{\pm}0.013\;g/cm^2$, %CV=0.48), Group 4에서 Mean${\pm}$2SD 및 %CV는, r값은 spine: $0.006{\pm}0.024\;g/cm^2$, %CV=0.86, r=0.995, Femur: $0{\pm}0.014\;g/cm^2$, %CV=0.54, r=0.998이였다. 결론 : HOLOGIC Spine Phantom과 LUNAR ASP %CV는 ISCD에서 규정한 정상오차 범위인 ${\pm}2%$안에 모두 포함되었고 BMD가 비교적 일정한 값을 유지하면 측정되어 뛰어난 재현성을 보였다. 하지만 Phantom은 환자의 체중이나 체지방 조성의 변화 등 임상적인 부분을 반영하는 데는 한계성을 갖고 있어 mis-calibration을 check하는데 유용할 것으로 판단된다. Group 3과 Group 4의 결과에서 환자를 하나의 장비로 두 번 측정한 값을 보았을 때와 두 대의 장비를 교차하여 측정한 값 모두 2SD값 이내에 포함되었고 선형회귀분석(Regression Analysis) r값이 0.99 이상으로 높은 정밀도와 상관도를 나타냄으로써 두 장비를 호환하여 추적검사를 시행하여도 영향이 없었다. 신뢰있는 BMD 산출을 위해서는 정기적으로 장비 및 검사자의 기능테스트와 이에 대한 적절한 교정행위가 이루어져야 할 것이다.

In the physicochemical property. the content of proximate composition of GL was higher 08.28% of moisture, 10.3% of crude protein, 78.4% of crude fiber) than that of CV, but the content of crude lipid and ashes of GL was higher than that of CV. 2. CV had relatively higher content of antioxidant components such as total phenol, carotenoids and v itamin C. than GL did. Antioxidant mineral components such as magnesium and zinc also had relatively higher in CV than in GL. 3. TBA value, conjugated diene production, LDL oxidation, DPPH of methanol extracts in CV and GL were as high as a-Tocopherol.

  • Four foreign pasture cultivars such as Lotus corniculatus cv. Maitland, Trifolium pratense cv. Deben, Lolium perenne cv. $S_{23}$ and .Dactylis glomerata cv. $S_{26}$ were tested with "Kwisan" series, a common upland soil in Southern part of Korea. The cultivars in single or mixture were grown in pot with two levels of light intensity, i.e. a full sun light condition and 50% interception. Dry matter yield of top and root and their seasonal changes, the number of tillers or branches per plant and finally competative effects of mixtures were evaluated by estimating the expected yield, relative yield totals and compensation index. The results are summarized as follows: 1. Maitland showed a significant decrease in dry matter yield in shade condition, but the number of branches of Maitland was higher than those of Deben. 2. Maitland showed higher dry matter yield than Deben during the mid-summer period, while $S_{23}$, showed higher dry matter yield than $S_{26}$ during early season. 3. Mixtures of $S_{23}$ and Maitland, and $S_{26}$ and Deben gave better response to grasses by increasing the number of tillers in shade condition. 4. Combinations of Lotus corniculatus cv. Maitland and Dactylis glomerata cv. $S_{26}$ and Trifolium pratense cv. Deben and Dactylis glomerata cv. $S_{26}$ gave higher relative yield totals and higher compensation index, which envisages that the pasture establishment rates can be enhanced when those mixtures were sown by the oversowing method in the upland soil where phosphate level is very low and infertile in general.n general.

  • Dysmenorrhea is one of the most common gynecologic disorders in menstruating women. Dysmenorrhea refers to the pain appearing in the lower abdomen and lower back before. after or during menstruation. In oriental medicine. the causes of dysmenorrhea have been recognized as something penetrated such as qi. blood. and pathologic factors. The purpose of this study was to observe the difference in the temperature between the Soyangin dysmenorrhea patients group and the Soeumin dysmenorrhea patients group by thermography. We observed the 55 dysmenorrhea patients that visited ** Oriental Medicine center from July 19 to August 27. 2004. We diagnosed the constitution by QSCCII and the body temperature was assessed by DITI. Thermographic measurements were performed on 3 areas(Chon-jung(CV17), Chung-wan (CV12), Kwan-won(CV4)). In this study we observed that the temperature of Chon-jung(CV17) is the highest and Chung-wan (CV12) is higher than Kwan-won(CV4). The temperature of Soeumin group is higher than that of Soyangin group in all areas and there is a significant difference in 3 area temperature between Soeumin group and Soyangin group.

  • 한의학의 뜸 요법은 잘 알려져 있으나, 현재까지도 쑥을 연소하여 시술하는 고전적 방식을 많이 사용하고 있다. 대체의학의 뜸 기기 개발에서, 뜸에서 반응하는 인체의 특징 및 요소들을 파악하는 것은 중요하다. 그러므로 본 연구에서는 뜸 요법에 대한 뇌파변화를 고찰하고자, 자극을 가하지 않은 무자극 대상군과 간접 뜸 방식을 적용한 대상군으로 나누어, 뜸 자극에서 중요하게 여겨지는 관원(CV4), 신궐(CV8), 그리고 중완(CV12)의 경혈 점에 자극을 주어 뇌파 변화의 특징을 비교 분석하였다.

  • 목적 : 본 연구는 간접구의 안전성에 대한 기초 데이터를 확보하기 위하여 수행되었다. 연구설계 : 50명의 건강한 성인을 무작위 배정으로 두 그룹으로 나누어 4주간 (일주일에 3회) 신궐혈과 관원혈에 뜸을 시술하였다. 시험군에 비하여 대조군은 열이 전달되지 않도록 단열제로 처리한 뜸으로 동일한 부위에 시술하였다. 첫 시술 1시간 전과 마지막 시술 1시간 후에 공복상태에서 채혈을 하여 혈액학적 검사를 시행하였다. 결과 : 혈액학적 검사에서 적혈구와 총 백혈구 및 백혈구의 종류별 절대수치와 상대수치에서 두 그룹 간에 특별한 차이가 없었다. 또한 혈청학적 검사에서 총 단백질, 알부민, AST, ALT, ALP, GGT, LDH, 요소질소, 크레아티닌, 총콜레스테롤 및 중성지방의 비교에서도 그룹 간에 차이가 없었다. 결론 : 본 연구는 건강한 사람에서 간접구의 시행 후 혈액학적 안전성을 처음으로 보고하는 것으로서, 향후 뜸의 연구를 수행시 중요한 비교 자료로 사용될 수 있을 것이다.

  • On the framework of stochastic gravitational wave background(SGWB) by compact binary systems, we studied the strain spectra of SGWB produced by cosmological cataclysmic variables(CV). For this we reviewed the empirical properties of CVs by using newly published CV catalogue and calculated the cosmological densities of CVs considering the galaxy luminosity function and cosmic stellar birth rate function. Assuming the secular evolution of CVs, we calculated the time scale of CV gravitational wave(GW) radiation and derived formulae for the strain spectra of SGWB by cosmological CVs.
