Background: Normalized cerebral blood volume (nCBV) can be measured using manual or semiautomatic segmentation method. However, the difference in diagnostic performance on brain tumor differentiation between differently measured nCBV has not been evaluated. Purpose: To compare the diagnostic performance of manually obtained nCBV to that of semiautomatically obtained nCBV on glioblastoma (GBM) and primary central nervous system lymphoma (PCNSL) differentiation. Materials and Methods: Histopathologically confirmed forty GBM and eleven PCNSL patients underwent 3T MR imaging with dynamic susceptibility contrast-enhanced perfusion MR imaging before any treatment or biopsy. Based on the contrast-enhanced T1-weighted imaging, the mean nCBV (mCBV) was measured using the manual method (manual mCBV), random regions of interest (ROIs) placement by the observer, or the semiautomatic segmentation method (semiautomatic mCBV). The volume of enhancing portion of the tumor was also measured during semiautomatic segmentation process. T-test, ROC curve analysis, Fisher's exact test and multivariate regression analysis were performed to compare the value and evaluate the diagnostic performance of each parameter. Results: GBM showed a higher enhancing volume (P = 0.0307), a higher manual mCBV (P = 0.018) and a higher semiautomatic mCBV (P = 0.0111) than that of the PCNSL. Semiautomatic mCBV had the highest value (0.815) for the area under the curve (AUC), however, the AUCs of the three parameters were not significantly different from each other. The semiautomatic mCBV was the best independent predictor for the GBM and PCNSL differential diagnosis according to the stepwise multiple regression analysis. Conclusion: We found that the semiautomatic mCBV could be a better predictor than the manual mCBV for the GBM and PCNSL differentiation. We believe that the semiautomatic segmentation method can contribute to the advancement of perfusion based brain tumor evaluation.

한방 설진 시스템의 자동화 과정에서 혀 영상 분할은 가장 중요한 분야이다. 그러나 대부분의 한방 설진 시스템의 혀 영상 분할 방식은 사용자 기반의 메뉴얼 방식이나 반자동 방식으로 제안되어 왔다. 따라서 본 논문에서는 한방 설진 시스템의 완전 자동화를 위해서 기존의 스네이크 알고리즘을 기반으로 한 혀 영상 분할의 새로운 방법을 제안한다. 제안한 방법은 기존의 스네이크 알고리즘을 개선한 방법으로서 설진을 위한 혀 영상 특성을 이용하여 포인트들이 안에서 밖으로 역추적하면서 스네이크 에너지 함수가 최소화될 수 있도록 내부 에너지 함수를 개선하였고, 외부 에너지를 계산하기 위해서는 계층적 공간 필터링 방법을 적용하여 잡음에 강인한 특징을 갖는다. 또한 제안한 방법은 표본영상 실험과 실영상 실험을 수행한 결과, 기존 스네이크 알고리즘보다 배경 잡음에 강인함을 보였으며, 임의의 포인트 한 개를 선택하고 해당 포인트의 시작점, 중간점, 끝점에서의 에너지 값을 분석하여 국소적 최저치에 빠지지 않는 강인함을 보였다.

Objectives : Visual check and X-ray are commonly used by chiropractors to estimate ieg length inequality, This study have three categories: diagnosis for anatomic leg length inequality; difference between anatomic and functional leg length inequality; theraphies for anatomic or functional leg length inequality. Methods : We referred to a PubMed site by using word of 'leg length [JU] J Manipulative Physiol Ther', only items with abstracts. Results : We searched 26 articles in J Manipulative Physiol Ther with the key word-Ieg length. Conclusion : 1. Radiographs were most accurate and commonly used by chiropractors to measure anatomic leg length inequality, clinically wood block, tape measure, visual check are acceptable. 2. There was no article about difference between anatomic and functional leg length inequality. 3. Heel lift was commonly used with conservative theraphy for anatomic leg length Inequality. 4. Chiropractors have not yet proved that the supposed positive effects are a result of a reduction of subluxation, The detection of the manipulative lesion in the sacroiliac joint depends on valid and reliable tests, Because such tests have not been established, the presence of the manipulative lesion remains hypothetical. Great effort is needed to develop, establish and enforce valid and reliable test procedures.

인체에서 발생하는 체열을 과학적으로 이용하여 질병을 진단하고 치료과정을 관찰하고 예후를 추측할 수 있는 Thermography는 현대의학의 임상 여러분야에서 응용할 수 있는 유용한 진단장비에 속한다 하겠다. 인체의 피부온도는 좌우 대칭적으로 온도분포를 나타내며 여러가지 생리학적인 원인에 의하여 온도는 변화할 수 있으며, 그러한 온도변화는 여러 질병과의 연관성을 갖게 된다. Thermography는 유방암세포의 증식에 따른 유방체표면의 초기온도 상승을 screening 함으로서 조기에 유방암을 발견할 수 있으며, 척추의 신경근 자극에 따른 체열분포를 파악함으로서 신경근의 이상유무 및 척추질환을 진단할 수 있으며, 말초 혈액순환 장애 등으로 인한 질환에 있어서도 뚜렷한 체표면 온도분포를 나타내 줌으로서 혈액순환의 장애분포를 시각적으로 관찰할 수 있는 이점을 지니고 있다. 또한 정형 물리치료 분야에 속하는 근-골격계 질환에 있어서의 근육통, 압통점, 염좌, 염증질환 등을 구별할 수 있고 나아가 치료 전후에 적외선 체열검사를 실시해 봄으로서 치료전이나 치료결과에 대한 객관적인 평가를 할 수 있다는데 큰 의의가 있다고 하겠다.

Background: Excessive pronation of the feet can cause excessive inner rotation of the femur, followed by increased stress in the gluteus maximum, increased front slope of the pelvis, and lumbar lordosis, which leads to lumbar pain. The aim of the present study was to use the navicular drop test to examine foot pronation that can cause lumbar lordosis and to determine whether the navicular drop is lower in patients diagnosed with lumbar disc than in patients without this diagnosis. Methods: The Navicular Drop score was set by subtracting the navicular height at a standing position from the navicular height in a sitting position. The Navicular Drop measurements for college student with and without Lumbar Herniated Intervertebral Disc were compared using an independent t-test. Results: The control group were measured right $7.44{\pm}2.96$ and left $8.04{\pm}3.23$. The experimental group were measured right $2.12{\pm}1.33$ and left $2.80{\pm}1.29$. Therefore significant difference was found between the two groups (p<0.05). Conclusions: The navicular drop affected lumbar herniated intervertebral disc.
