The subject of this study was male apparatus gymnastics athlete who had scored high points doing basket with 1/2 turn on parallel bars. Then 3D motion analysis were used to calculate & analyse kinematic variables of Basket with 1/2 turn to Handstand. 1. The total average time spent for Basket with 1/2 turn took $2.16{\pm}.08sec$, at the downward upward phase took $.58{\pm}0.00sec$, $.23{\pm}.00sec$, at flight phase took $.28{\pm}.01sec$, at connected area phase took $.72{\pm}0.21sec$, at rotation area phase took $.35{\pm}.14sec$. To have a successful performance, there should be faster speed and velocity to rotate at the downward upward phase, then the upward velocity and height must be used adequately. Moreover, the speed must be faster at the flight connect phase to stabilize Center of Mass(CM) for the body, and must secure more time at the rotation area to have more stable performance. 2. After handstand on parallel bars while moving CM to right hand side, and It must be performed with big and magnificent performance with putting both hand's center to far away from the parallel bars. 3. Furthermore, CM must be moved fast from downwards to right hand side, and CM must be moved fast in vertical movement at upward and flight phase to avoid CM from moving back and forth, and left and right. 4. At downwards, the subject must rotate as bis as possible using hip-joint as wide as possible and at upwards, must put his body to vertical to have stable performance. While rotating or turning, it is better to do with bigger shoulder angle and have to make sure that trunk angle must be not scattered. To perform better and more positive in basket with 1/2 turn on parallel bars, the centrifugal force must be used big and fast at downward, and at upward and flight phase, downward movement must change to vertical movement as soon as possible while turning movement must happen at handstand position. Time spent must be shorten at connected area to stabilize CM and turning must be natural as possible while securing the necessary time of movement to well-balanced. Also, the body must be vertically closed from the ground.

Background: The purpose of this study was to investigate whether tidal volume (TV) of 8 mL/kg without positive end-expiratory pressure (PEEP) and TV of 6 mL/kg with or without PEEP in pressure-controlled ventilation-volume guaranteed (PCV-VG) mode can maintain arterial oxygenation and decrease inspiratory airway pressure effectively during one-lung ventilation (OLV). Methods: The study enrolled 27 patients undergoing thoracic surgery. All patients were ventilated with PCV-VG mode. During OLV, patients were initially ventilated with TV 8 mL/kg (group TV8) without PEEP. Ventilation was subsequently changed to TV 6 mL/kg with PEEP ($5cmH_2O$; group TV6+PEEP) or without (group TV6) in random sequence. Peak inspiratory pressure ($P_{peak}$), mean airway pressure ($P_{mean}$), and arterial blood gas analysis were measured 30 min after changing ventilator settings. Ventilation was then changed once more to add or eliminate PEEP ($5cmH_2O$), while maintaining TV 6 mL/kg. Thirty min after changing ventilator settings, the same parameters were measured once more. Results: The $P_{peak}$ was significantly lower in group TV6 ($19.3{\pm}3.3cmH_2O$) than in group TV8 ($21.8{\pm}3.1cmH_2O$) and group TV6+PEEP ($20.1{\pm}3.4cmH_2O$). $PaO_2$ was significantly higher in group TV8 ($242.5{\pm}111.4mmHg$) than in group TV6 ($202.1{\pm}101.3mmHg$) (p=0.044). There was no significant difference in $PaO_2$ between group TV8 and group TV6+PEEP ($226.8{\pm}121.1mmHg$). However, three patients in group TV6 were dropped from the study because $PaO_2$ was lower than 80 mmHg after ventilation. Conclusion: It is postulated that TV 8 mL/kg without PEEP or TV 6 mL/kg with $5cmH_2O$ PEEP in PCV-VG mode during OLV can safely maintain adequate oxygenation.

For the establishment of ready made Hanbok for the people in their 20's this study aims to develope Bagi-chogori pattern that revives the esthetic quality of the traditional Hanbok as well as comfortably fit the body. Direct method was used in Measuring the 33 parts of men which was selected as items needed for the analysis of the body and the development of patterns. In accordance with the body measurement and the analysis of the result the bust girth and height which has interrelation was chosen as the standard size for the development of pattern. Men's Baji-chogori(Korean traditional Jacket and Pants) which doesn't request fitness for instance we drew out a cross table by giving 5cm intervals each for breast waist hip girth and height. Size system of Baji-chogori was 4 steps. 1st was bust 95cm height 165cm 2nd was bust girth 95cm height 170cm 3rd was bust girth 100cm height 175cm and the 4th was bust girth 105cm height 180cm. In the case of Men the grouping of bodies was attempted by concentrating on the difference of the drop amount(Bust girth to hip girth), However 90% of men in their 20's showed a silhouette of an inverted triangle. Therefore attempt for an additional grouping wasn's Only calculation concerning the ease amount of items such as bust which and length was considered to enhance the silhouette of Hanbok when worn. Men's body for instance have a tendency to change to a rectangular shape as they get older. specially the abdominal girth trend to increase greatly. So study and development of pattern should be made for all age groups.

The purpose of this study was to analyze the gait characteristics and interaction between lower extremity joints according to shoe's heel heights in young women. Participants were selected as subject consisted of young and healthy women (age: $23.71{\pm}1.49yrs$, height: $165.92{\pm}2.00cm$, body weight: $54.37{\pm}3.46kg$) and walked with 3 types of shoe's high-heel (0, 5, 9 cm). The variables analyzed consisted of the displacement of Y axis in center of mass ([COM]; (position, velocity), front rear(FR) and left right(LR) angle of trunk, lower extremity joint angle (hip, knee, ankle) and asymmetric index (AI%). The displacement of Y axis in COM position showed the greater movement according to increase of shoe's heel heights, but velocity of COM showed the decrease according to increase of shoe's heel heights during gait. The hip and knee angle didn't show significant difference statistically according to increase of shoe's heel height, but left hip and knee showed more extended posture than those of right hip and knee angle. Also ankle angle didn't show significant difference statistically, but 9 cm heel showed more plantarflexion than those of 5 cm and 0 cm. The asymmetric index (AI%) showed more asymmetric 9 cm heel than those of 0 cm and 5 cm. The FR and LR angle in trunk tilting didn't show significant difference statistically according to the increase of shoe's heel height during gait in young women.

양전자 방출핵종은 511 keV의 감마선을 방출하기 때문에 기존 140 keV의 99mTc에 비해 종사자의 방사선 피폭의 증가로 피폭선량 저감을 위한 노력이 요구된다. 본 연구는 환자에게로부터 일정거리에 따른 선량률 변화를 확인하고 차폐를 이용하여 외부선량률의 변화를 알아보았으며 환자 주변의 외부선량 분포에 대한 영 향을 분석하여 방사선 종사자의 피폭 관리에 도움이 되고자 하였다. 10 명의 환자를 대상으로 하였으며 평균연령은 $47.7{\pm}6.6$ 세였다. 환자의 키는 평균 $165.5{\pm}3.8cm$, 몸 무게 평균은 $65.9{\pm}1.4kg$으로 비슷한 몸무게의 환자를 대상으로 하였다. 머리, 가슴, 복부, 무릎, 발끝 쪽의 위치에서 10 cm, 50 cm, 100 cm, 150 cm, 200 cm 위치에서 측정하였고 측정 후에 즉시 이동형 방사선 차폐체을 설치한 후 머리와 가슴, 복부 부분에서 100 cm, 150 cm, 200 cm 거리에서 선량률을 측정하였다. 거리에 따른 선량률 변화와 차폐 전, 후의 투과율을 구하였다. 평균 10 cm 거리에서는 머리 부분이 $105.40{\mu}Sv/h$로 가장 높게 나타났으며 발 부분에서 $15.85{\mu}Sv/h$로 가장 낮게 나타났다. 200 cm 거리에서는 머리, 가슴, 복부 부분에서 비슷한 선량률이 나타났다. 머리 부분에 서 차폐 전 100 cm에서 $9.56{\mu}Sv/h$, 150 cm에서 $5.23{\mu}Sv/h$, 200 cm에서 $3.40{\mu}Sv/h$로 나타났으며 차폐 후에는 100 cm, 150 cm, 200 cm 에서 각각 $2.24{\mu}Sv/h$, $1.67{\mu}Sv/h$, $1.27{\mu}Sv/h$로 측정되었다. 가슴 부분에 서 차폐 전 100 cm에서 $8.54{\mu}Sv/h$, 150 cm에서 $4.90{\mu}Sv/h$, 200 cm에서 $3.44{\mu}Sv/h$로 나타났으며 차폐 후에는 100 cm, 150 cm, 200 cm 에서 각각 $2.27{\mu}Sv/h$, $1.34{\mu}Sv/h$, $1.13{\mu}Sv/h$로 측정되었다. 복부 부분에 서 차폐 전 100 cm에서 $9.83{\mu}Sv/h$, 150 cm에서 $5.15{\mu}Sv/h$, 200 cm에서 $3.18{\mu}Sv/h$로 나타났으며 차폐 후에는 100 cm, 150 cm, 200 cm 에서 각각 $2.60{\mu}Sv/h$, $1.75{\mu}Sv/h$, $1.23{\mu}Sv/h$로 측정되었다. 투과율은 거리에 따라 증가함을 알 수 있었다. 거리가 멀어질수록 선량율이 낮아지는 것을 확인할 수 있었으며 차폐를 하였을 경우 차폐를 하지 않았을 때보다 1 / 4 정도 더 낮아지는 것을 확인할 수 있었다. 검사를 진행하는 근무자는 환자와의 거리를 멀리 할 수 없기 때문에 방사선 피폭이 증가할 수밖에 없다. 따라서 적절한 차폐를 한다면 방사선 종사자의 방사선 피폭을 줄 일 수 있을 것이다.
