연구 목적: 본 연구는 탄성의치 제작 시 주로 사용되는 polyamide를 수종의 연마방법을 사용하여 처리 후 Candida albicans의 부착정도와 표면거칠기를 비교하고자 하였다. 연구 재료 및 방법: 25×15×2 mm 크기의 polyamide 시편을 4군으로 나누어 연마재를 사용하여 기공용 lathe 연마하는 방법(기공실내 연마방법)과 각기 다른 2종의 실리콘 포인트로 진료실내 연마하는 방법, 그리고 실리콘포인트 연마 후 pumice로 연마하는 방법으로 처리하였다. C. albicans의 부착성을 평가하기 위해 5×106 CFU/ml의 C. albicans 현탁액에 시편을 2시간 동안 침적하였고 5회 수세처리 후 한천배지에서 배양하였다. 그리고 주사전자 현미경(JSM-5900, JEOL LTd., Tokyo, Japan) 촬영을 시행하였다. Profilometer (Surf-pak; Kawasaki, Japan)를 이용하여 표면거칠기를 측정하였고 통계처리를 위하여 SPSS 18.0 프로그램을 사용하였다. 일원변량분석으로 비교 분석하였고 사후검증은 C. albicans의 부착성 검증을 위해 Scheffe test를 시행하였으며 표면조도검증을 위해 Tamhane’s T2 test를 시행하였다(α=.01). 결과: 최대 거칠기 값을 보인 군은 2단계의 연마용 버를 사용한 것으로 0.32 ㎛±0.10 값을 나타냈으며, 가장 낮은 거칠기 값을 보인 것은 tungsten carbide를 사용하지 않고 기공용 lathe로만 연마를 한 군으로 0.02 ㎛±0.00의 거칠기 값을 나타냈다. C. albicans 부착 실험에서는 기공용 lathe만을 이용한 연마방법이 가장 적은 부착수를 보였으며 다른 세 군과 유의한 차이가 발견되었다(P<.01). 결론: 표면거칠기 및 미생물 부착능 실험 결과 기공실 연마만을 시행한 경우 유의하게 낮은 거칠기 값과 부착율을 보였다. Pumice로 추가 연마한 군은 진료실연마를 시행한 군에 비해 낮은 거칠기 값을 보였으나 C. albicans 부착에 있어서는 유의한 차이를 보이지 않았다(P>.01). Purpose: The purpose of this study was to compare the effect of 3 chairside polishing methods and laboratory polishing methods on surface roughness and C. albicans adhesion of polyamide denture base. Materials and methods: Using contact profilometer, the surface of polyamide specimens (25×15×2 mm) was studied after conventional polishing without finishing and after chiarside polishing with 2 chiarside polishing kits and chairside-pumice polishing following finishing with tungsten carbide bur. To evaluate the adhesion of C. albicans, C. albicans suspension was overlayed on the test specimen. And the specimens were incubated for 2 hours. Imprint culture method was achieved and counted the colony on the agar plate. Polished polyamide were evaluated using a scanning electron microscope. The statistics were conducted using one-way ANOVA and in case of difference, Scheffe test and Tamhane’s T2 test were used. Results: Surface roughness (Ra) of surfaces polished with 2 chairside polishing kits had higher than conventional polishing and pumice polishing. The highest roughness value was 0.32 ± 0.10 ㎛, and the lowest was 0.02 ± 0.00 ㎛. The adhesion of C. albicans on the specimens polished with chairside polishing group and pumice polishing group were increased than conventional polishing group (P<.01). Conclusion: Conventional laboratory polishing was found to produce the smoothest surface and the lowest adhesion of C. albicans. Two groups polished with Chairside polishing kits were similar with respect to surface roughness. Surface of the specimen polished with pumice is significantly smoother than 2 chairside polishing groups, but the result of C. albicans adhesion is that group polished with pumice was similar with 2 chairside polishing groups (P>.01).

To evaluate the efficacy of the single agent therapy for the initial management of fever in neutropenic patients, we conducted a prospective randomized trial comparing imipenem/cilastatin alone with a combination of piperacillin and amikacin. Among 40 evauable episodes of fever, stratum A(hematologic malignancy, n=30) consisted of 15 imipenem group and 15 piperacillin plus amikacin group and stratum B consisted of 10 cases with solid tumor. There was no difference in age, sex, duration of neutropenia, initial granulocyte count and number of cases with severe neutropenia(<100/㎣) between two groups. Overall response rate to imipenem was higher(86.6%) than combination therapy group(53.5%) in stratum A, but statistical difference was not found. Overall response rate to imipenem in solid tumor was 100% whereas to combination therapy group was 40%. There was no serious toxicity on imipenem use. We conclude that imipenem monotherapy could be an effective & safe empirical therapy in the treatment of febrile neutropenic patients.

The purpose of this study was to examine behavioral types of efficient soccer coaches by identifying relationship between athletic satisfaction and leadership behavior types of high school soccer coaches. who have an impact on soccer players. The study also took a closer look at the types of leadership behavior shown by soccer players depending on their school level, position and status-whether or not a key player or a bench warmer. A total of 287 high school soccer players were subjected to the study and the Leadership Scale for Sport (LSS) and the Satisfaction Scale for Soccer Players were used to obtain the study results. In terms of leadership behavioral type by school level. good schools were found to hold higher levels of perception on instruction behavior. autocratic behavior. democratic behavior and social support behavior than the relatively poor schools. No significant difference was found in terms of leadership behavior type by position. However, the analysis on the leadership behavior type by players status showed that the key players had a higher perception on instruction and training behaviors than the bench warmers. According to the athletic satisfaction by school level, no significant difference was found in sub-variables. The same was true for both athletic satisfaction by position and athletic satisfaction by players status. In terms of correlation between the leadership behavior type and athletic satisfaction, training and instruction behavior. democratic behavior, social support behavior and positive feedback behavior were found to have a significant correlation with the sub-variables of athletic satisfaction, which are, sport performance satisfaction and psychological satisfaction. Moreover, the leadership behavior type, training and instruction behavior and autocratic behavior were identified as variables that have a significant impact on sport performance satisfaction and psychological satisfaction, which are sub-factors of athletic satisfaction.
