The Purpose of this study was to empirically examine the relationships of flow experience, self-efficacy and performance level on activity level of boxing players. From the analysis of this study, the following conclusions were obtained : 1. There was a partial difference in boxing player's activity level, flow experience and self-efficacy by socio-demographic variables. First, in the activity level of boxing player, there was a difference both family income and performance level. The majority in the exercise career, the period of middle school boxing player was less than 2 years, high school boxing player less than 4 years and university boxing player less than 8 years. In the flow experience, cognitive flow experience did show the difference in the exercise career. The more exercise career, the lower cognitive flow experience was perceived. As the school record gets higher, the self-efficacy was increased and the performance level was higher in the ordinary group by school record. 2. There was a partial difference in the flow experience according to the activity level of boxing player. That is say, middle school boxing player was higher the perceived level for cognitive flow experience than the others, university boxing player was lower. But the behavioral flow experience according to the activity level of boxing player, did not show the difference. 3. The flow experience of boxing player had a partial influence on the self-efficacy. The cognitive flow experience of boxing player affected positively on the self-efficacy, while behavioral flow experience did not have any influence on the self-efficacy. 4. The flow experience of boxing player had a partial influence on the performance level. That is to say, the cognitive flow experience of boxing player affected positively on the performance level. 5. The self-efficacy of boxing player affected positively on the performance level. 6. There was a partial casual relation in the flow experience, self-efficacy, performance level of boxing player. The cognitive flow experience of boxing player affected positively on the performance level by the self-efficacy, cognitive flow experience and self-efficacy affected positively, directly on the performance level. But the behavioral flow experience did not have any influence directly or indirectly on the self-efficacy and performance level.

The properties of a machine tool greatly affect machining quality since a machine tool has large variance in its features. Machine tool makers want to find best machining condition with the one that they have built. Machine builders need to develop test specimen since it helps finding characteristics of machine tools when the machining properties of the specimen are analyzed. This paper develops test specimen to identify features of the main spindle, the feeding device, and the frame of a machine tool. The specimen is machined with a high speed machine and the features of the machine are analyzed with test items. They are surface roughness, overshoot in axial movement, errors in circular movement, feeding with small movement, and compensational error. This work can improve usability for a machine tool in machining practice.

It has been recently reported the possibility in the bansfer of antimicrobial resistance to other animals and humans. In particular, vancomycin resistant enterococci (VRE), which have been known as a principal antimicrobial resistant bacteria in humans, have been increased as a pathogen of nosocomial infections. And then animal VRE were suspected as an origin of human VRE. In this study, we isolated Enterococcus spp. from animals, identified by bio- chemical tests, examined for antimicrobial susceptibility, and then compared the antimicrobial susceptibility of VRE among each other as well as human VRE. Enterococcus iecium (29%) was predominant in Enterococcus species (n=122) isolated from animal feces in this study. E. hirae, E. iecalis, E. casseliflam and E. gallinarum were also isolated as rates of 24%, 21%, 16% and 7%, respectively. The resistance of enterococci to penicillin and tetracycline were 66% and 78%, respectively, and the susceptibility of them to chloramphenicol was 66%. Antimicrobial susceptibility test has shown that 91% of VRE from humans (n=11) was susceptible to chloramphenicol and all resistant to penicillin, rifampin and streptomycin. Seventy-five percentage of VRE from chickens (n = 12) was susceptible to rifampin and resistances of them to penicillin, tetracycline and sbeptomycin were 75%, 83%, and l00%, respectively. Therefore, we confirmed the difference of antimicrobial susceptibility from animals and humans, and the antimicrobial susceptibility test could be one of the simple and useful methods for the epidemiological survey of VRE.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

It has been recently reported the possibility in the transfer of antimicrobial resistant to other animals and humans. In particular, the occurrence of vancomycin resistant enterococci (VRE), which have been known as a principal antimicrobial resistant bacteria in humans, has been increased as a pathogen of nosocomial infections. And then animal VRE were suspected as an origin of human VRE. In this work, we investigated the relatedness between VRE from animals and humans through random amplified polymorphic DNA (RAPD) typing. The genetic relatedness of vanA, vanB, vanC-1 and vanC-2 genotypes was examined by RAPD typing, respectively. van4 genotypes have not been shown high genetic relationship each other, containing VRE from humans (n = 8) and chickens (n = 5). In vanB genotypes from humans (n = 3), 2 isolates were made up one cluster, shown 77.8% homology. Chicken isolates of vanC-1 genotypes (n = 11) were constituted 2 clusters and the homology of 2 clusters was 81.8% and 80.0%, respectively. In case of vanC-2 genotypes (n = 19), 2 isolates from pigs have been shown 76.9% homology. But, between VRE from animals and humans, the isolates of high genetic relationship could not be found and RAPD typing was a useful epidemiological method that could be confirmed the genetic relationship among VRE.

The purpose of this study was to analyze the effects of three different pelvic tilts on sit-to-stand ativities and to suggest a new therapeutic approach for movement reeducation in patients who have difficulty with sit-to-stand activities. The three different pelvic tilts were: (1) comfortable pelvic tilt sit-to-stand (CPT STS), (2) posterior pelvic tilt sit-to-stand (PPT STS) and (3) anterior pelvic tilt sit-to-stand (APT STS). To analyze the kinematic component of STS, a motion analysis system (Zebris) was applied to the ankle, knee, hip joint, and thigh-off area. Also, to determine the onset time of muscle contraction, surface electrodes were placed to the rectus femoris muscle (RF), the vastus lateralis muscle (VL), the biceps femoris muscle (BF), the tibialis anterior muscle (TA), the gastrocnemius muscle (GCM), and the soleus muscle (SOL). One-way repeated ANOVA was used for the statistical analysis. First, significant differences were found in kinematic variables for the hip, knee, ankle joint, and thigh-off among the three activities. Second, there was significant difference in muscle activation pattern in TA, VL. and BF among three activities. In conclusion, the findings of this study suggest the following evaluative and therapeutic approach for STS activity: (1) Changes in knee and ankle joints should be prioritized and recruitment order differences in VL and RF can be generated to accomplish abnormal STS activity. (2) APT STS can be introduced for movement efficiency and functional advantage when abnormal STS is treated.

The purpose of this study was to empirically examine the relationship among anomie and adaptation behavior with activity level of boxing players. From the analysis of this study, the following conclusions were obtained : 1. A boxer's adaptive behavior according to the special aspect of popularity statistics shows partially difference : The group whose household is less than ￦800,000 tends to higher formalism, in contrast, the group less than ￦2,500,000 shows the lowest. And the group whose grades are average tends to show higher avoidable and opposing behavior, the group which is below average shows relatively low. 2. There is difference for anomie according to the level of boxer's activity : The higher the boxer's level of activity, the higher anomie awareness the boxer has. 3. There not any difference for adaptive behavior according to the boxer's level of activity : The boxer's level of activity dies not affect to his conformity, innovation, ritualism, retreatism, and rebellion. 4. The boxer's anomie affects to his adoptive behavior : It affects to his conformity, innovation, ritualism, retreatism, and rebellion.
