This study was undertaken to investigate the effect of exercise induced pulmonary hemorrhage(EIPH) on the finishing position of racehorses, 400 bleeders(305: 1 time, 76: 2 times, 19: 3 times, total: 514 cases) which had bled(EIPH) from their nostrils after their races at the Seoul racecourse during the 5 years period('93-'97) were analyzed for this study. The ratio of bleeders to total racehorses in finishing position 1-3,4-6, 7-9 or above 10 was 0.55, 0.84, 0.90 or 1.13%, respectively. There is tendency to higher incidence of bleeding in the later positioned racehorses group. To analyze the correlation between EIPH and finishing position, finishing potion of each EIPHed horses' was checked at 7 successive races(3 races each before/after EIPH. The average final position at the -3rd race, -2nd racer -lst racer EIPHed race, 1st race,2nd race and 3rd race of each bleeder was 5.85. 5.94, 6.21, 7.32, 7.20, 6.51 and 6.53, respectively. Raring times were adjusted to 1,000 m equivalent. Average racing times of the -3rd race,-2nd racer -lst raced EIPHed race, 1st race, 2nd race and 3rd race of each bleeder was 67.1, 67.1, 67.2, 67.6, 67.5, 67.4 and 67.3 second, respectively. Bleeders which finished the race within 1 second following the winners were 25. 3% of total bleeders. The rest 74.7% reached at the finish line 1 second later than the winners. Particularly 46.3% of bleeders were above 2 second later. Therefore this study suggested that bleeding has effect on performance of the racehorse, consequently it make bleeders be placed later positions.

In this paper, a self-propulsive and small concrete floor finishing trowel robot with twin trowels is proposed. Due to the small size and omni-directional moving capability, it is adequate for small space such as apartment. By adjusting the posture of trowels, it can move in any direction without wheels. We used cheap PIC processor for the cost saving design of the modules and adopted mode processors for easy operation of control stick. For the position control of the robot, we made a motion control algorithm appealing to the stepping motor driver module and the wireless communication module between the robot and PC (or control stick). In this paper, we discuss the control problem of the floor finishing robot in order to move to the right position. By comparing experimental result with simulation, we show the validity of the robot mechanism, sensors, and the control system.

교정 치료 후 이상적인 교합과 양호한 심미적 결과를 얻기 위해서 일반적으로 교정 장치 제거하기 4개월에서 7개월 전에 detailing을 시행한다. 이와 같은 과정을 finishing이라고 하며, 이 과정은 최종적인 양호한 결과를 얻는데 있어서 필수적이다. 일부 교정의는 finishing을 위한 특별한 이론적 근거 및 기준 없이 이 과정을 교정 치료의 마지막 단계에서 시행하면 되는 것으로 여기고 있다. 그러나, 최종적인 양호한 교정 치료 결과를 얻기 위해서는finishing 과정이 총 치료 계획의 부분으로 치료의 초기 단계에서부터 고려되어야만 하며, 교정 장치 제거를 위한 이론적 근거 및 기준에 근거한 finishing을 위한 checklist가 필요하다. 이 checklist는 크게 네 부류로 분류할 수 있다. 즉, 교합 요인, 심미적 요인, 치주적 요인과 습관적 요인으로 분류할 수 있다. 교합 요인에서 점검해야할 요소로는 alignment, marginal ridge discrepancy, interproximal contact, anterior inclination, posterior inclination, overjet, overbite, arch form과 functional occlusion 등이 있다. 심미적 요인에는 gingival form, crown form, crown width과 crown length 등이 있다. 치주적 요인에는 root angulation, bone level 등이 있다. 습관적 요인에는 mouth breathing, tongue position at rest, tongue thrust habit, lip biting, nail biting과 finger sucking 등이 있다.

An operation planning of lift car is crucial in tall building construction especially it's arrangement plans, because it is related with transportation distance of finishing materials affecting construction productivity. Since tall building construction, composed of complicating and huge plane have complex traffic lines of finishing materials, to determine the position of lift car empirically or intuitively has limits. Therefore this paper suggest an optimum layout model of lift car minimizing the transportation distance both at site-level and floor-level using Graph theory and Dijkstra algorithm.

Acoustical properties of chestnut and paulownia woods have been determined in four film thicknesses of oriental lacquering and cashew varnishing on double surfaces of soundboard to elucidate effects of finishing. Accelerometer was attached to the specimen at one third position from one end, and specimen was hit by the impact hammer at one third position from opposite end. Data were processed by vibration analyzer. The ratio of axial-to-transverse sound velocity of untreated specimens of chestnut and paulownia were 3.25 and 5.34, respectively. Natural frequency, specific Young's modulus, acoustical coefficient, sound velocity, damping of sound radiation(DSR) and acoustical converting efficiency(ACE) decreased by oriental lacquering and cashew varnishing for both species. Damping of internal friction of chestnut decreased by oriental lacquering and cashew varnishing, but that of paulownia increased. Natural frequency. specific Young's modulus, acoustical coefficient, sound velocity, and DSR decreased with increased film thickness of both finishing materials. However, damping of internal friction and ACE showed irregular tendency with increased film thickness. Acoustical properties of cashew varnished chestnut specimen were better than those of oriental lacquered specimen. Acoustical properties of oriental lacquered paulownia specimen were better than those of cashew varnished specimen.

This paper addresses the factors hindering the image quality of lines in inkjet printed on polyester fabric as printing media. Lines were printed onto different types of polyester fabrics in warp and filling directions. Line image quality including line width, edge blurriness, and edge raggedness was assessed. The effect of capillary wicking on line image quality of printed spun polyester fabric is discussed. The factors on the image quality include printing position(top of the yam or between the yarn), printing direction(warp or filling), yarn structures(filament or spun), thread size(yam or fiber), finishing, and ink properties(evaporation rate). More than 30% differences in image quality results were observed by changing the printing location on the spun polyester fabric. The best results of the image quality were obtained with the printed plain and spun polyester fabrics. The fiber sizes may affect capillary size; therefore, the image quality can be dissimilar. Types of finishing materials and inks greatly improve the line image quality on spun polyester fabrics.
