The purpose of this study was analyzed the effect of kinematical and kinetical factors of lower extremity of form change in the cause of growth an unborn child during in pregnancy. Three pregnant women were selected from pregnant 24 weeks as subjects. Each subjects were required to walk with usual walking speed. Cinematographic and GRF data were collected during walking, and the kinematical and kinetical variables were calculated using Kwon3d. Based on the results of the study, the following conclusions were drawn : 1. Step width and Step length Step width according to the period of pregnancy was gradually small but step length was gadually great. 2. Angle of lower extremity The angle of hip, knee and ankle was differed pregnancy on 9 month and other time. 3. Ground reaction force In the three part of ground reaction force, pregnancy on 9 month was most greater than other time.

The purpose of this study was analyzed the effect of foot scan analysis form change in the cause of growth an unborn child during in pregnancy. Five pregnant women were selected from pregnant 16 weeks as subjects. Each subjects were required to walk with usual walking speed(1.0~1.2m/s). Foot scan analysis data were collected using foot scan multistep program during walking. The data was described to compared with kinematics quality in present peak value. Based on the results of the study, the following conclusions were drawn : 1. The change of form during the period of pregnancy was statistically found significant in H1 on p<.001, in M2, Ml on p<.05, but it was not effect in H2, M5, M4, M3(Maximum pressure ratio). 2. The change of form during the period of pregnancy was not statistically found significant in support time ratio. 3. The change of form during the period of pregnancy was statistically found significant in R4, R5 on p<.01, p<.05, but it was not statistically found significant in R1, R2, R3, R6, R7, R8, R9(Force ratio at support).

The study are to examine the effects of the target distance of the body segments' kinematical variables through a use of 3-D analysis technique. The selected kinematical variables were the angle of the ankle, the knee and the hip joint at touch-down, the joint height, the center of the mass the stride length and touch down time. Four female volleyball players who engaged in the commercial team were participated in this study. Two video cameras were used for the data collection. In this study, the spiking movements were divided into two target distance (A quick, back attack) for the data analysis. From those, the selected kinematical variables were calculated, and the following conclusions were drawn ; 1. Back attack was the smaller the ankle, the knee and the hip angle at touch-down phase than A qiuck. 2. Back attack was the higher the jump height than A qiuck. 3. Back attack was the higher the center of mass than A quick. 4. Back attack was the longer stride length during approach and touch-down phase than A quick. 5. Back attack was the slower the touch-down time than A quick.

The purpose of this study are to examine the kinematical variables of throwing motion in bowling. The selected kinematical variables were the joint angle of lower and upper extremity at release, the length of stride, the height of center of mass, the velocity of the wrist, elbow and shoulder from stance position to release the ball. Four male bowling players in H university were participated in this study. One camera was used for data collection of 2-D DLT. The camera was located at the right side of bowler. Also a control object containing 12 markers of known coordinates encompassed the space of the throwing movement. After the selected kinematical variables were calculated, the following conclusions were drawn ; 1. The shortest stride length was showed at first step, but the longest stride length was showed at last step before release the ball. 2. The players decreased the CM at beginning of backswing, and then gradually increased the CM until end of the backswing. Also the players maintained the low CM until release the ball. 3. At release, the players maintained 55.5° of ankle joint, 135° of knee joint, 100.2° of hip joint, 20.7° of leaning body angle with extended arm. 4. The fastest movement was showed the shoulder joint at backswing, but the fastest movement was showed the wrist joint at release.

본 연구는 임신 40주와 출산후 6주간에 있는 임산부의 보행 동작의 특정을 규명함으로써 이와 관련된 연구자들에게 기초자료를 제공하고자 실시하였다. 이를 위해 임신 4주에 있는 임산부를 대상으로 1차 실험을 실시하였으며 동일한 대상자를 출산후 6주에 2차로 실험하여 자료를 수집하였다. 디지타이징 시 오차를 최소화하고 인체관절점의 분별을 위해 21개의 반사마커를 부착하였다. 10m의 보행주로를 걷는 동안 두 대의 비디오카메라를 이용하여60Hz로 자료를 수집하였으며 동시에 100Hz 지면반력자료를 수집하였다.수집되어진 자료는 DLT 방법을 사용하여 분석하였으며 이의 분석에 Kwon3d 프로그램을 활용하였다. 분석결과 다음과 같은 결론을 얻었다. 1. 임신 40주와 출산 후 6주의 보행 시 지지시간과 스윙시간의 비율이 다르게 나타났으며 보폭과 보간, 활보장은 임신 40주에서 더 큰 값을 보였다. 상체 전경각 역시 임신 40주에서 더 큰 값을 보였다. 힙관절, 무릎관절, 발목관절각도는 S1이 출산후 6주에서 큰 값을 보인반면 S2는 출산전후에 큰 변화를 보이지 않다. 2. 상하지면반력의 경우 FP1과 FP2는 임신 40주보다는 출산 6주에서 큰값을 보였지만 FP3는 임신 40주에서 보다 큰값을 보이고 있었다. 전후지면반력의 경우 출산전과 후 모두 Fy2에서 보다 큰 값을 보이고 있었다. This Study was to investigate kinematical characteristic comparison of the gait pregnant 40weeks and after delivery 6weeks 20´s women and provide the basic data. To accomplish this study, in the first, carry out an experiment with the pregnant women in the pregnant 40weeks on the videotape, and than the second, make an experiment with the kinematic data. Kinematic data were filtered with a low-pass, fourth-order Butterworth filter with an effective cut off frequency of 6Hz. The conclusions were drawn as follows; 1. Floor contact Periods(stance and swing rate) were differed from before and after the delivery and a pregnant 40 weeks was greater than after delivery 6 weeks in the step, width, stride. Also, a pregnant 40 weeks was greater than after delivery 6 weeks in the front angular. And the other angular components were represented similar pattern. 2. In the vertical load, delivery 6 weeks was grater than a pregnant 40 weeks in the FP1(first peak) and FP2(valley). And FP3(second peak)was represent that a pregnant 40 weeks was greater than delivery 6 weeks. Also, in the horizontal shear, Fy2(progressional force)was greater than Fy1(breaking force) about time of the delivery.

Staphylococcus aureus is an important food-borne pathogen, which is present on the skin and mucosa of animals. Some of the S. aureus strains are causative agent of food poisoning syndrome. The aim of this study was to investigate the antimicrobial resistance of S. aureus isolates from raw meats in slaughterhouses during 2010. From 17,874 raw meat samples tested, a total of 190 S. aureus were isolated, for which antimicrobial susceptibility to 17 agents was examined using broth dilution method. Among isolates from beef, chicken and pork, 20 (51.3%), 20 (24.7%) and 9 (12.9%) were sensitive to all antimicrobials tested, respectively. Isolates from pork and chicken meats showed much higher resistance, compared to isolates from beef. Penicillin resistance was the most frequent among isolates from beef (35.3%) and pork (75.7%), while tetracycline resistance was among those from chicken meats (48.1%). A total of 3 methicillin resistant S. aureus (MRSA) were detected from beef (5.1%, 2/39) and pork (1.4%, 1/70). Although the prevalence of MRSA was low, the presence of antimicrobial resistant S. aureus such as MRSA suggests that further investigation and strict surveillance on MRSA and antimicrobial resistance are needed.
