Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

The purpose of this study was to investigate the effect of the kinematic variables on take-off motion of the long jump. A typical high speed film analysis technique including DLT method was adapted to record and analyze total of eight long jumps performed by elite weman athletes at a track and field events. The following were found that: The relationship between take-off horizontal velocity and flight length was significantly related as r=0.6105 respectively at p<0.049 level. However, it was not possible to find the relationship between touch-down horizontal velocity and flight length. It was not possible to reveal the relationship between the touch-down vertical velocity, take-off vertical velocity and flight length. The relationship between take-off velocity and flight length was significantly related as r= 0.7080 respectively at p<0.025 level. However, it was not possible to find the relationship between touch-down velocity and flight length. The relationship between the body lean angle at take-off and flight length was significantly related as r=0.8468 respectively at p<0.004 level. However, it was not possible to find the relationship between the body lean angle at touch-down and flight length. And the relationship between the body COG height at take-off and flight length was significantly related as r=0.6583 respectively at p<0.038 level. However, it was not possible to find the relationship between the body COG height at touch-down and flight length. The relationship between the take off distance and flight length was significantly related as r= 0.7966 respectively at p<0.009 level. The relationship between the foot contact time and flight length was significantly related as r=0.6414 respectively at p<0.047 level.

This study was conducted to investigate relationship between the angular momentum of the long jump takeoff phase and flight distance performed by elite athletes. Eight male athletes who achieved at least the 3rd place in the long jump at the Korea National Track and Field meetings during 1993 and 1994 were selected as subjects. The long jump motions performed by the subjects were recorded using two 16mm high speed cameras at the nominal speed of 100 frames per second. The Direct Linear Transformation technique was adopted from the beginning of filming to the final stage of data extraction. The movement patterns during the last stride for run-up, takeoff, and the flight distance were related using regressional method with the biomechanical consideration. It was found that: The mean shank angular velocity at the instant of takeoff was -4.96±2.48rad/s, regression equation of flight distance (Y) prediction was Y=-0.1055·(shank angular velocity)+6.2916 (r=0.63, P<0.0001). The mean tatal relative angular momentum (absoute angular momentum/subject's mass·height²) with respect to a transverse axis through the center of gravity at the instant of touchdown was -0.134±0.050, regression equation of flight distance (Y) prediction was Y=-0.1055·(tatal relative angular momentum)+6.5971 (r=0.64, P<0.0001). And The mean tatal relative angular momentum with respect to a transverse axis through the center of gravity at the instant of takeoff was -0.424±0.117, regression equation of flight distance (Y) prediction was Y=2.1304·(tatal relative angular momentum)²+6.4182 (r=0.62, P<0.0001). Therefore, in order to increase flight distance, several conditions must be fulfilled at the instant of takeoff leg touchdown and takeoff during takeoff phase. First, the active landing style described as clawing the ground with the sole of the takeoff foot should be performed during the takeoff leg touchdown and takeoff. Second, the total forward angular momentum with respect to a transverse axis through the center of gravity should be increased during the takeoff leg touchdown and takeoff.

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Endometriosis in the abdominal scar following cesarean section is very rare condition among the extrapelvic endometriosis. The frequency of abdominal wall endometriosis secondary to cesarean section is from 0.03% to 0.8% in some reports. It is difficult to diagnosed in spite of the typical symptoms. The typical symptom is aching swelling in the area of the surgical scar, which is influenced by the phases of menstruation. The definitive diagnosis is established by pathologic analysis. Surgical excision remains the treatment of choice. The majority of patients presented from 1 to 2 years after the precipitating operation. We experienced an unusual case of abdominal wall endometriosis presented over 10 years after cesarean section, who was admitted to our hospital complaining of recurrent left lower abdominal pain. So, we report this case with a brief review of the concerned literatures.

The purpose of this study is to analyse the kinematical variables for the successful head attack factors in Kumdo bouts. The bouts included 34 games of 27 preliminary matches for President Cup held in November 2000 were filmed by two video cameras. The DLT technique of 3-dimensional image analysis for calculation of players and their bamboo sword in coordinates value and then the pace, speed, angle between bamboo sword and ground, angular velocity of bamboo sword's first part, attack distance, and stroke time that give impact on the outcome of the match when attacking head were analyzed. Among the kinematical variables that showed the significance in statistics were the pace, attack distance, and the stroke time. This finding implies that although their direct impacts were not significant the other factors could have indirect impact on attacking head. Thus, the attacker should practice for successful performance.

The purpose of this study was to investigate the effect of lower leg planting angle an on take-off motion of the long jump. The Achilles tendon angle defined as the angle between shank and calcaneus with projection to XY plane was introduced to interprete lower leg motion uring last foot touch for the flight phase of long jump. A typical high speed film analysis technique including DLT method was adapted to record and analyze total of nineteen long jumps performed by elite athletes at two different track and field events. The following were found that: 1. The relationship between touch-down velocity, take-off velocity, range of vertical velocity and flight length were significantly related each others as r=0.6383, 0.6395 respectively at t=0.01 level. 2. It was not possible to reveal the relationship between take-off angle and flight length. Due to highly consistent take-off angles shown between the long jumpers. 3. The angular displacement of the shank during the last foot contact just before flight phase was negatively related to the flight length(r= -0.6149). However, it was not possible to find the relationship between the aehilles tendon angle and flight length. 4. As the range of the body C.O.G lean angle increased the last step foot contact time significantly increased(r=0.8625). 5. The foot contact time of Korean elite long jumpers was somewhat longer than that shown by foreign Athletes. It is concluded that maintaining touch-down velocity during initial phase of foot touch and increasing take-off velocity would result optimal take-off angle and good record. Decrease in the angular displacement of the shank, foot contact duration, and the range of body C.O.G lean angle were found to be important to improve the flight length.

Juvenile polyp, also known as a retention polyp because they contain mucin cysts, is a relatively common hamartomatous lesion in chlidhood. It occurs in 1-2% of children and young adults; however it is uncommon in adulthood. Juvenile polyp is rare in the first year of life and is thus presumed to be acquired and not congenital. It is pedunculated, 2-3 cm in size, red-tan in colour, smooth and always shows fluid filled cystic spaces on cut surface. Histologically, Juvenile polyps are hamartomatous with distended, mucus-filled glands, often with cystic dilatation and edematous lamina propria containing abundant vasculature. The most common manifestation is rectal bleeding produced by auto-amputation of the polyp. Juvenile polyp has been considered not to be at increased risk of developing carcinoma. However, atypical epithelium is observed in some lesions, especially in larger polyps, which may give rise to adenoma and subsequent malignant transformation. Therefore the diagnosis of solitary juvenile polyp should not be made only with colonoscopy and biopsy, but should be totally resected endoscopically for pathologic evaluation. About 90% of the lesions are solitary and localized within 20cm from anal verge. In Korea, there are some reports of juvenile polyps located in the rectosigmoid colon. We report one case of juvenile polyp in adolescent that presented as a hematochezia & abdominal pain, which is located at right colon.
