This study suggested the categorization of the notion, the factors and process of axial coding deducted through grounded approach as a research to verify the instruction experiences and educational significance of survey of university athletic club coaches. As a result of open coding, first, a total of 135 terms, 22 subcategories, and 11 upper categories were suggested. Second, as a result of axial coding, 6 paradigms were composed in the instruction experiences and education significance of university athletic club coaches. As for the casual conditions, university coach life, becoming a coach after retirement, and charm of the job were suggested, and as to the situational context, it was deducted as the relation formation with athletic students. Furthermore, as a central phenomenon, the professional instruction method was shown. In this connection, instruction contents and experiences are suggested as an interventional condition. As for the interaction, such as communications and successful instructors are found as a strategy of interaction. As a result of this process, it was found that athletic club coaches acquire the educational contents know-how and methods applicable for each level for themselves. Third, as selective coding, the outline of a story about the instruction method specialization process of athletic club coaches were performed, and the core categories were discovered in this process. It was understood that through not only improvement of educational contents but also instruction methods and various curricula about the specialization process, the individual “Know-how” of a coach, namely, empirical knowledge is naturally accumulated.

Purpose : To evaluate the quantitative accuracy of three-dimensional (3D) images by means of comparing distance measurements on the 3D images with direct measurements of dry human skull according to slice thickness and scanning modes. Materials and Mathods : An observer directly measured the distance of 21 line items between 12 orthodontic landmarks on the skull surface using a digital vernier caliper and each was repeated five times. The dry human skull was scanned with a Helical CT with various slice thickness (3, 5, 7 mm) and acquisition modes (Conventional and Helical). The same observer measured corresponding distance of the same items on reconstructed 3D images with the internal program of V-works 4.0 (Cybermed Inc., Seoul, Korea). The quantitative accuracy of distance measurements were statistically evaluated with Wilcoxons’ two-sample test. Results : 11 line items in Conventional 3 mm, 8 in Helical 3mm, 11 in Conventional 5 mm, 10 in Helical 5 mm, 5 in Conventional 7 mm and 9 in Helical 7 mm showed no statistically significant difference. Average difference between direct measurements and measurements on 3D CT images was within 2 mm in 19 line items of Conventional 3 mm, 20 of Helical 3 mm, 15 of Conventional 5 mm, 18 of Helical 5 mm, 11 of Conventional 7mm and 16 of Helical 7 mm. Conclusion : Considering image quality and patient’s exposure time, scanning protocol of Helical 5 mm is recommended for 3D image analysis of the skull in CT.

A study on the indirect fluorescent antibody test(IFAT) using the sectioned egg antigen in the liver of white rats was performed. The antigen used was prepared in 6~8㎛ thickness by frozen section at -20℃ of nonembryonated C. hepatica eggs deposited in the liver tissue after 6 weeks of infection. Fluorescein isothiocyanate (FITC) conjugated anti-rat IgG (Goat) was diluted by 64 fold in phosphate buffered saline (PBS, pH 7.2) and counterstaining with a 1/10,000 solution of Evans blue was effected while the fluorescent conjugate is acting by diluting the labelled antiglobulin in the Evans blue solution instead of in the PBS. A total of 22 white rats (B.W. 150g) was divided into 2 groups (A, B) and 200 and 2,000 embryonated eggs were infected orally. All rats were bled by retro-orbital puncture prior to infection and weeks of 1, 3, 5, 7, 9 and 13 after infection. As negative control sera, 60 normal rats were used. Eggs for infection were cultured at room temparature for 4~5 weeks in 0.5% formalin. IFAT was processed by the modified method of Wilson et al. (1974). The results obtained were summarized as follows; 1. The localization of antigens in frozen section of non-embryonated eggs of C. hepatica detected by IFAT was seen on the inner membrane of egg shell. 2. IgG titers detected by IFAT rapidly increased in 3 weeks after infection, thereafter the titers were kept until 5 weeks and gradually decreased in 7 weeks to 9 weeks, then converted into normal by 13 weeks. 3. IgG titers distributed from 16 to 1,024 and showed highest titers in 3 and 5 weeks. 4. Mean titers of 3, 5, 7, 9 weeks after infection were higher in group B than in group A.

The bioequivalence of generic simvastatin tablet(Dongsung Pharmaceutical Co.) to the simvastatin tablet(Zocor^(®), MSD Korea Co.) as a reference drug. Single dose of 20 mg simvastatin was administered to 20 healthy male volunteers in a balanced, randomized crossover design with a washout between the two study periods. Blood samples were collected up to 12 hours and plasma concentration of simvastatin was measured by well validated LC-MS/MS. Pharmacokinetic parameters were analyzed by non-compartmental analysis and ANOVA test was used for the statistical analysis of parameters. No statistically significant formulation, period, or sequence effect was encountered. Ninety percent confidence intervals of log transformed C_(max) and AUC_(t) were comprised in the stipulated 0.80-1.25 range. These results suggest that test formulation of simvastatin is bioequivalent with the reference, both formulations in 20 mg tablet.

Hemolytic uremic syndrome is characterized by Coombs-negative microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure in infant and children. At present, E. coli 0157 : H7 and other verotoxin-producing E. coli(VTEC) seem to be a major cause of this illness. The majority of patients have a prodrome of bloody diarrhea, and acute renal failure develops several days to weeks later. Although an optimal treatment remains unknown, the general management of hypertention and renal failure with early and frequent dialysis is the mainatay of treatment, and intravenous administration of immunoglobulin G is like to be effective. We experienced a case composed of bloody diarrhea, seizures, coma, and anuria in 1 year old girl who was diagnosed as HUS and recovered renal function completely with slight impairment of cognitive ability and behavioral function. We presented this case with a review of literatures.

The bioequivalence of generic cefixime(Pofixim^(®), Kwangmyung Pharmaceutical Co.) capsule to the cefixime capsule(Suprax^(®), Dong-A Pharmaceutical Co.) as a reference drug. Single dose of 100 mg cefixime was administered to 20 healthy male volunteers in a balanced, randomized crossover design with a washout between the two study periods. Blood samples were collected up to 14 hours and plasma concentration of cefixime was measured by well validated reverse phase high-performance liquid chromatography. Pharmacokinetic parameters were analyzed by non-compartmental analysis and ANOVA test was used for the statistical analysis of parameters. No statistically significant formulation, period, or sequence effect was encountered. Ninety percent confidence intervals of log transformed C_(max) and AUC_(t) were comprised in the stipulated 0.80-1.25 range. These results suggest that test formulation of cefixime can be declared bioequivalent with the reference, both formulations in 100 mg capsule.

In this study, sttempt has been made to evaluate the effect of CO₂laser irradiation on enamel surface structure and the bond strength of sealant material. Conventional acid etching was used as a control technic for comparison. The results obtained from this experiment were as follows: 1. The highest mean shear bond strength value was observed in samples of Group Ⅰ(acidetching) with the statistical significance(p<.05) between all the other groups. 2. The shear bond strength in Group Ⅳ was the lowest among laser etching groups. but there were no significant difference berween them(p>.05). 3. Scanning electron microscopic observation showed that the rough and irregular surface was created by CO₂laser treatment with the formation of numerous pores, micro-cuacks, and small bubble-like inclusion. Increasing the energy density induced localized surface melt with a thin smooth glaze-like appearance. 4. In acid-etched control stecimen cohesive failure predominated. whereas adhesive failure was the main mode in laser-treated group. Based upon the above-mentioned results, it can be assumed that the CO₂laser is not an adequate substitute for the acid-etch technique in enamel preconditioning. More studies are required to explore the effective condition of laser irradiation which could attain the better bond strength of restorative materials.
