This study will be targeting 21-24 years old college students majoring in physical education. This study covers the effect of kinesiology taping and icing treatment on the recovery rate of blood lactate concentration, and cardiovascular function so that it can provide the basic data for improving physical performance. As a result of this study, Kinesio taping and icing aid the recovery rate of the maximum load of lactic acid recovery rate and 30 minutes after exercise heart rate after exercise, but increased, after 15 minutes, immediately after exercise heart rate, exercise lactate and heart rate, and 30 minutes after exercise lactate showed no difference. In conclusion, Kinesio taping and icing treatment, reduce pain and fatigue but it is not satisfactory. Further study, applying a more accurate and technical form of exercise programs needs to continuously research the effects of Kinesio taping and icing treatment

Difference in recovery behaviors from the circular deformation of natural rubber (NR) composites aged in air and distilled water, respectively were investigated. Recoveries of the samples aged in air were larger than those of the samples aged in distilled water. Recovery rates of the samples reinforced with filler were faster than those of the unreinforced ones. Recovery rates of the carbon black-filled samples were faster than those of the silica-filled ones. Difference in the recovery behaviors according to the aging media can be explained by the crosslinking density changes and the annealing effect.

While the repeated traffic loading accumulates the damage of asphalt pavement, the damage has being healed during rest periods. And then, this healing enhances the fatigue life of asphalt pavement. A method was developed to determine the healing rate of asphalt mixture in terms of recovered dissipated creep strain energy (DCSE) per unit time, and the healing properties of four different asphalt mixtures were evaluated. The test procedure consists of repeated loading test and periodical resilient modulus tests. A normalized healing rate in terms of $DCSE/DCSE_{applied}$ was defined to evaluate the healing properties independently of the amount of damage incurred in the mixture. From the test results, it was concluded that the healing rates of asphalt mixtures were increased exponentially as the temperature was increased and more affected by the structural characteristics of mixture such as asphalt content than the binder characteristics such as the polymer modification.

It was attempted in this experiment to observe the effect of ginseng saponin on the growth and recovery rate of Saccharomyces rouxii which was shocked by heat-stress. The growth of S. rouxii was found most active when the saponin concentration in the malt extract broth was $10^{-3}%$ And the growth rate of S. rouxii grown on medium containing $10^{-3}%$ ginseng saponin was faster thanh that of the yeast grown on medium without saponin from the early log phase of the yeast. The growth recovery rate of S. rouxii which was heat-shockied by $80^{\circ}C$ - 30 minites was accelerated in the medium added ginseng saponin.

모바일 장치에서 많이 사용되는 플래시 메모리는 작고, 저전력을 사용하며 내구성을 지니는 비휘발성 저장장치이다. 플래시 메모리의 읽기 속도는 램과 비슷하며, 대용량화 되어가고 있지만 쓰기 속도가 램에 비해 느리고, 블록에 대한 쓰기가 제한되어 있다. 현재의 디스크 기반의 DBMS 와는 달리 플래시 메모리용 저장장치를 설계함에 있어 트랜잭션 실패시의 회복기법이 같은 블록에 다시 쓰기가 불가능한 플래시 메모리의 특성을 고려하는 것이 중요하다. 본 연구에서 LFS에 Shadow Paging을 응용하여 플래시 메모리의 블록에 대한 쓰기 횟수를 줄이고 플래시 메모리의 특성에 맞추어 트랜잭션 실패시 효율적인 데이터 복구를 가능하게 하는 회복기법을 제안한다.

Purpose : The purpose of this study was to evaluate factors affecting hematologic recovery and infection in high-dose chemotherapy(HDCT) and autologous stem cell transplantation(ASCT) in patients with high-risk solid tumor. Methods : From January 2004 to December 2005, 72 HDCTs and ASCTs were applied to children with high-risk solid tumor at Samsung Medical Center. Medical records of these 72 HDCTs and ASCTs were retrospectively analyzed. Results : The single most powerful predictor of neutrophil and platelet recovery was the number of transplanted $CD34^+$ cells. The duration of high fever was significantly longer in young patients, in patients treated with total body irradiation and/or thiotepa, and in patients transplanted with lower $CD34^+$ cell dose(<$2{\times}10^6/kg$). However, the difference in the duration of high fever according to the number of $CD34^+$ cells was not clinically significant. Conclusion : Findings in this study suggest that HDCT and ASCT with low $CD34^+$ cell dose is clinically feasible despite delayed hematologic recovery, especially at a dose >$1{\times}10^6/kg$ per transplantation. Therefore, it is important not to defer the appropriate time for HDCT for an additional collection of hematopoietic stem cells if the number of collected $CD34^+$ cells is >$1{\times}10^6/kg$ per transplantation.

본 연구에서는 디퓨저의 압력회복을 높이기 위해 디퓨저 입구에 실린더를 설치하여 후류가 압력회복에 어떤 영향을 미치는지 알아보았다. 2D-Incomp-2.1-P 해석자를 이용하여 속도, 압력에 따른 유동가시화를 통해 내부유동을 분석하였고, 압력회복계수를 비교하여 디퓨저 입구에 설치된 실린더의 후류가 디퓨저 성능에 어떤 영향을 주는지 비교하였다. 그결과 실린더를 설치하였을 때 확대부에서의 박리영역이 더 작아졌고 압력회복계수가 더 높아졌다.

We purified crude urushiol from natural lacquer produced in Korea, China, and Japan and then isolated several urushiol congeners known to induce allergic reactions. The 3 major kinds of urushiol congeners that were isolated and purified were RV-l (C$_{21}$H$_{34}$O$_2$, M.W. 314.462), RV-2 ((C$_{21}$H$_{32}$O$_2$, M.W. 316.240) and RV-3 ((C$_{23}$H$_{34}$O$_2$, M.W. 342.515), occupying 80% of total crude urushiol. The content of RV-l was the highest in natural lacquer from China at 70.07%, and was the lowest in that from Japan at 62.38%. However, the content of RV-2 in natural lacquer from Japan was 9.25%, 2$\sim$3 times higher than those from Korea (4.28%) and China (3.09%). As an allergy inducing character, RV-l had strong inducing power and durability in the primary stage, showing slow recovery. RV-2 had weak power in the primary stage and also showed slow recovery. Although RV-3 had comparatively weak power at the primary stage, it induced the strongest allergy contact dermatitis after 48 hr. However, it recovered to nearly the same level as control group 72 hr after sensitization time. Accordingly, we found out that RV-1 is the most influential of urushiol congeners in inducing allergic reactions, natural lacquer from China having the most inducible strength and slowest recovery compared to those from Korea and Japan.

돌발성 난청은 환자에게 듣지 못하게 된다는 공포를 야기하는 질환이며 아직 확실한 병인이나 치료법이 확정되어 있지는 않다. 저자들은 인제의대 서울백병원 이비인후과에서 입원 및 동일한 치료를 받은 15례의 돌발성 난청 환자에 대하여 임상 분석하여 다음과 같은 결과를 얻었다. 1) 청력회복은 Siegel의 분류로서 완전회복 1례, 부분회복 2례, 경도회복 5례, 무회복이 7례이었다. 2) 현훈이 있었던 10례중 4례에서만 회복이 있었으나 현훈이 없던 5례중 4례가 회복되었다. 3) 청력손실이 완전농인 8례중 6례에서 무회복이었다. 4) 발병 8일 이내인 경우 치료시작 시기와 청력 회복사이 에는 연관이 없었다. 5) 적혈구침강속도(ESR)과 청력회복 사이에는 연관이 없었다.

This study was conducted to investigate the effects of static recovery and dynamic recovery methods on heart rate, blood lactic acid concentration, and blood glucose during recovery after walking at the speed of 80bpm and 130+30bpm upon trekking of forest slopes in Taejo Mountain in Cheonan. 9 men in their 20s and 30s who had no abnormality in walking was subject to this experience. The result of through static recovery and dynamic recovery methods while trekking at the speed of 80bpm and 130+30bpm were analyzed by two-way repeated ANOVA. When there was a significant difference, the repeated method of contrast was applied to compare and analyze. The heart rate at 80bpm condition was significantly different depending on the method(p=.008) and time(p=.000) and there was no significant difference in blood lactic acid concentration for the recovery method(p=.401), but there was a significant difference depending on the time(p=.000). Blood glucose did not show significant difference according to the recovery method(p=.093), and there was significant difference depending on the time of static recovery method(p=.002). The heart rate in 130bpm + 30bpm condition was significantly different depending on to the method(p=.002) and time(p=.000), blood lactic acid concentration was significantly different depending on the method(p=.001) and time(p=.000), and blood glucose concentration was not significantly different between the time(p=090) and the method(p=.721).
