목적: 슬관절 손상 원인에 따른 골멍의 위치 및 빈도를 조사하여 전방십자인대 손상과 골멍의 상관관계를 분석하고자 하였다. 대상 및 방법: 2006년 1월부터 2010년 12월까지 외상성 슬관절 동통을 주소로 내원한 환자 중 MRI 촬영 이후 전방십자인대 손상이 진단된 환자 87예를 대상으로 하였다. 슬관절 MRI를 이용하여 동반된 구조물 손상 및 그에 따른 골멍의 위치 및 빈도를 분석하였다. 골멍의 위치는 대퇴골과 경골에 대해 전후방 및 측방의 MRI 영상으로 나누고 각각의 영역에 대하여 다시 내측, 중앙, 외측 3구역으로 분류하였다. 골멍은 Costa Paz가 제시한 분류법을 이용하였다. 결과: 일상 생활 손상은 전체 87예 중 32예(37%), 스포츠 손상은 22예(25%), 교통사고 손상은 33예(38%)로 나타났다. 일상생활 손상의 경우 대퇴골에서는 내과의 전방 부분, 경골에서는 고평부 전방의 내측부에 골멍이 나타났다(각각 p=0.024, p=0.021, p=0.025, p=0.029). 스포츠 손상은 대퇴골에서는 외과의 중심 부분과 경골에서는 고평부 후방의 외측부에서 골멍이 나타났다(각각 p=0.014, p=0.015, p=0.018, p=0.017). 교통사고 손상은 대퇴골과 경골에서 골멍이 전반적으로 관찰되었다(각각 p=0.264, p=0.254, p=0.229, p=0.267). 결론: 일상 생활 손상이나 스포츠 손상의 경우 손상 기전이 교통사고 손상보다 통계적으로 유의한 골멍의 분포를 보이는 것으로 나타났다. 특히 골멍이 경골 외측 고평부 및 대퇴골 외과에 있는 경우에는 스포츠 손상에 의한 전방십자인대 손상을 강력히 의심할 수 있는 근거가 될 수 있을 것으로 사료된다.

In this retrospective study the effect of positioning on the radiographic appearance of duodenum and the radiographic differences of duodenal gas pattern between dogs without pancreatitis and dogs with pancreatitis were investigated. Ventrodorsal, dorsoventral as well as both lateral abdominal radiographs of 255 dogs were evaluated. Gas distribution in the duodenum, gastroduodenal angle, accuracy of the positioning was examined. The duodenum was more visible in a left lateral view and a dorsoventral view. The positioning of dorsoventral view was the most inaccurate. Based on this study, there were not significant differences in duodenal gas pattern between dogs without pancreatitis and dogs with pancreatitis.

Purpose: The present study examined the reproducibility of an operation plan by comparing the jaw position of STO with the postoperative mandibular set back measurement in sagittal split ramus osteotomy. Methods: Thirty patients with class III dental and skeletal malocclusion and who were treated with BSSRO were reviewed. Three plain radiographs such as the panoramic view, the lateral cephalogram and the submentovertex view were taken before and after operation. Also, paper surgery for STO and model surgery were used to evaluate the amount of mandibular set back. Results: On the panoramic view, the amount of mandibular set back in STO was similar to the postoperative results of model surgery, but the amount of mandibular set back on the lateral cephalogram was smaller than the postoperative result of model surgery and then the amount of set back on submentovertex view was similar to the postoperative result of model surgery. Conclusion: Precise tracing and paper surgery should be performed for a combined expected STO in order to predict the exact amount of preoperative mandibular set back.

Discoid meniscus has been well known to a frequent anomaly of meniscus and much reported in diagnosis and treatment. But, associated X-ray findings have not been known well. We reported its significance of X-ray findings in discoid meniscus. From May 1995 to May 1997, 31 cases of discoid meniscus were compared with 51 cases of nondiseoid meniscus both confirmed by arthroscopy, with simple X-my findings. Both groups were evaluated by X-ray findings in view of lateral joint space widening, peripheral spur of lateral joint space, sclerotic change of lateral tibial plateau, concave lateral tibial plateau, flattening of lateral femoral condyle, hypoplasia of lateral femoral condyle and high riding fibula. The results of analysis were as follows: 1. Widening of lateral joint space, sclerotic change of lateral tibial plateau and cupping of lateral tibial plateau were statistically significant in discoid meniscus. 2. X-ray findings in discoid meniscus were not associated with patient's injury history and symptom duration. 3. Other X-ray findings were not related in discoid meniscus significantly. X-ray findings with patient's history and physical examination arc helpful in the diagnosis of discoid meniscus.

This study dealt with the comparison of lateral baring capacity for vertical PHC pile between predicted and measured values driven in weathered granite soils to build world cup gymnasium in Kwangju area. Recently, the calculation of horizontal bearing capacity of piles foundation has been considered very important for earthquake or wind resistant design in Korea. During this study , Matlock & Reese, Broms and Chang's methods were selected in prediction of lateral resistant of PHC piles. As for case study, the prediction values were compared with 5 measured ones based on ASTM. The result showed that prediction values proposed by Matlock & Reese , Chang and Broms were smaller that real values. Three proposed methods by Matlock & Reese and Chang based on lateral deflection and Broms by ultimated lateral resistance turned out valid in view of engineering practice.

In current practice of earthquake resistant design the equivalent lateral force procedure is widely used for its simplicity and convenience. But the equivalent lateral force procedure is derived based on the assumption that the dynamic behavior of the structure is governed primarily by the fundamental vibration mode. Therefore proper prediction of dynamic responses of the structure is unreliable using the equivalent lateral force procedure when the effect of higher vibration modes on the dynamic behavior is negligible. In this study design seismic load which can reflect the effect of higher vibration modes is proposed from the point of view of proper assessment of story shears which have the major influence on the design moment of beams and columns. To evaluate the effect of higher modes, differences between the story force based on the equivalent lateral force procedure specified in current earthquake resistance building code and the one based on modal analysis using design spectrum are examined. From these results improved design seismic load for the equivalent lateral force procedure which can reflect the effect of higher vibration modes is proposed.

A new genus and species of marine dinoflagellate from the open western equatorial Pacific Ocean, Gynogonadinium aequatoriale gen. et nov. sp., is described from light and scanning electron micrographs. This laterally compressed unarmoured taxon had a triangular cell body in lateral view with two different elongate extensions. The end of the apical extension was spherical with a groove that arises from the epicone in the ventral side of the cell. The antapical extension was longer. The dorsal part of the cingulum showed undulated lists in each margin. The nucleus was ellipsoidal and perpendicularly crossed the cingulum. Dimensions of cells were 90-110 μm long and 43-55 μm wide in lateral view at the level of the cingulum. Gynogonadinium is placed in the order Gymnodiniales, family uncertain.

Objective: The purpose of this study is to evaluate the disc block subluxation for lumbar scoliosis and herniation of nucleus pulpous (HNP). Methods: We used AP & Lateral view X-ray for patients. And we measured of disc wedge angle, vertebral body rotation to evaluate the typical and atypical disc block subluxation. Results: On the analysis of the lateral view X-ray, 4th lumbar intervertebral disc angle (I.V.D angle) showed $4^{\circ}$, $5^{\circ}$, $3^{\circ}$, $0^{\circ}$ in the cases. On the 4th lumbar analysis of the AP view X-ray, lumbar scoliosis showed right disc wedge angle was $11^{\circ}$ (case 1), $17^{\circ}$ (case 2) and left vertebral body rotation was 13mm, 6mm. Lumbar HNP showed left disc wedge angle was $5^{\circ}$ (case 3), $4^{\circ}$ (case 4) and left vertebral body rotation was 2mm, 4mm. Conclusions: Disc block subluxation has been in lumbar scoliosis, but not been in lumbar HNP.
