The division of the right ventricle into two chambers by aberrant muscle bands traversing the sinus portion, Double Chambered Right Ventricle[DCRV], is a relatively rare congenital cardiac malformation. Double Outlet Right Ventricle[DORV], basically recognized by the origin of both great arteries from the morphologic right ventricle, is also a rare anomaly; its frequency has been reported as approximately 0.09 case per 1,000 birth. DORV associated with DCRV, unusual combination, is even more rare; only a few known cases have been recorded previously in the literature. This report presents our surgical experience with this rare anomaly, DORV with DCRV.

Pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals is a rare and complex lesion in which great morphologic variability exists regarding the sources of pulmonary blood flow. We report a case of this disease with no true central pulmonary arteries in a 9-month-old-boy successfully treated by one-stage complete unifocalization and repair from a midline stemotomy approach.

The sediment resuspension and diffusion model is an integral part of a sediment transport and morphologic change model. We examined a vertical one-dimensional sediment resuspension and diffusion model using field data collected at about 10-m depth off the Saemangeun $4^{th}$ dike. The field data include waves, currents and suspended sediment concentration near the bed for about a day in May, 2007. The suspended sediment concentration obtained from the 1D model overestimated the observation about two orders of magnitude with single grain size and multiple grain sizes. The incorporation of the bed armoring effect, which adjusts the amount of suspended sediment with the available bed sediment, improved the agreement between the model and observation within a factor of two.

비디오 객체 분할은 MPEG-4와 같은 객체 기반 코딩 단계를 위한 중요한 구성 요소이다. 새로운 MPEG-4 비디오 표준은 움직임 객체의 모양 정보를 고려하여 높은 효율의 부호화 뿐만 아니라 움직임 객체에 대한 내용기반 기능의 부호화를 수행한다. 본 논문은 비디오 시퀀스에서 움직임 객체 분할을 위한 새로운 알고리즘과 VOP(Video Object Plane) 추출 방법을 소개한다. 본 알고리즘은 첫 번째 프레임을 기준영상으로 설정한 후 두 개의 연속된 프레임 사이의 차이 값으로부터 시작된다. 즉 차이영상을 추출한 후 차이영상에 Canny 에지를 적용하고 다음 프레임의 영상에 Canny 에지와 morphologic일 연산을 적용하여 정확한 움직임 객체 에지(Moving Object Edge)를 생성한다. 이후 생성된 에지를 이용하여 VOP를 추출한다. VOP 추출 단계에서 더욱 정확한 움직임 객체 에지를 얻기 위하여 morphological 연산을 수행하였다.

We investigated whether the CT images of hepatic lesions could be analyzed by computer-aided diagnosis (CAD) tool. We retrospectively reanalyzed 14 liver CT images (10 hepatocellular cancers and 4 benign liver lesions; patients who presented with hepatic masses). The hepatic lesions on CT were segmented by rectangular ROI technique and the morphologic features were extracted and quantitated using fractal texture analysis. The contrast enhancement of hepatic lesions was also quantified and added to the differential diagnosis. The best discriminating function combining the textural features and the values of contrast enhancement of the lesions was created using linear discriminant analysis. Textural feature analysis showed moderate accuracy in the differential diagnosis of hepatic lesions, but statistically insignificant. Combining textural analysis and contrast enhancement value resulted in improved diagnostic accuracy, but further studies are needed.

The water celery, Oenanthe javanica DC., is widely distributed in Korea and the other South East Asian countries. From ancient times, the water celery has widely been used for food or medicine. In herbal medicine, the water celery has a medical actions which are defervescence, diuresis, hypotensor, appetizer. Recently, studies on the water celery are briskly being conducted. For example, studies on the morphologic property and classifications of origin of the water celery, studies on the chemical constituents of the Water celery, studies on the bio activities of the water celery which contains flavonoids. However, there is not studies of hematological changes in dogs administrated the water celery until now. Consicontly, this study was conducted to observe the hematological changes in dogs administrated excessive amount of the water celery concentrated extract for a long period. In this studies, all dogs showed significantly decrease of the RBC, PCV, Hb and MCHC, and increase of the WBC, MCV, GSH and reticulocytes, but did not significantly change in the Met-Hb.

The mitral valve is not a simple but a complex structure, mitral valve complex. This complex is composed of mitral orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There were many controversies about this structures. We studied mitral valve complex in 63 cases of normal Korean adults, such as the circumference of mitral annulus, the intercommissural diameter, height and breadth of the cusps, including commissure, the ratio of rough to clear zone, breadth of the achordal zone, the number of scallops of posterior cusp, the number, length and the pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

A seven month old female infant with isolated ventricular inversion and anatomically corrected malposition of the great arteries in situs solitus, associated with ventricular septal defect, patent ductus arteriosus, right-sided juxtaposition of left atrial appendage, is reported. The patient showed usual atrial arrangement with somewhat superoinferior relation, a discordant atrioventricular connection, and a concordant ventriculoarterial connection with aorta in the right-sided position. A normal sized left atrium was connected to the left superiorly positioned morphologic right ventricle through a tricuspid valve, which crossed the left ventricular outflow tract anteriorly. Well developed bilateral[subaortic and sub-pulmonary]conus was documented at operative field. successful surgical repair was done by performing the Senning procedure and by closing the ventricular sepal defect with a patch through the right ventriculotomy. The infant’s postoperative course was uneventful with normal sinus rhythm. Postoperative cardiac catheterization revealed no hemodynamic obstruction or residual shunt.

Using laser ablation technique carbon thin films were deposited on Si(100) substrate as a function of substrate temperature. In this study, the surface morphologic, structural and field emission properties of these carbon thin films were investigated using Raman spectroscopy, scanning electron microscopy, and a diode technique, respectively. With increasing of the substrate temperature, the surface morphologies were changed significantly. Moreover, the intensity of D-band and the full width at half maximum of these bands were dependent on substrate temperatures. As the substrate temperature was increased, the field emission properties were improved. As the result, we find that the field emission properties of the films were changed significantly with the substrate temperature and structural features of carbon than films.

Allergic contact dermatitis is a common skin disease resulting from specific immunologic sensitization to topically applied various allergen. The Purpose of this study was to investigate skin morphologic cahnges by light microscopic and scanning electron Microscope, changes of protein band by SDS-PAGE(SDS-polyacrylamide gel electrophoresis) in the skin effectiveness for beruty improvement of Geranium essential oil on skin troubles by surfactant. The results of the study are as follows, 1. From the observed result of FE-Scanning Electron Microscope, groups treated by Geranium essential oil in group treated Geranium essential oil during 1 week in surfactant treated group during 1 week, the group was repaired in irregularity surface of tissue by alleviate-keratinization of Geranium essential oil. 2. As a result of protein analysis the group treated on surfactant was rised protein upper range of 97,0004a11on by hyper-keratinization and group treated during 1 week by surfactant was decreased protein below range of 43,000dalton.
