Background : Coding of principal diagnosis is essential component for producing reliable health statistics. We performed this study to evaluate the current practice of principal diagnoses determination and coding, and to give some basic data to improve coding of principal diagnosis. Method : Nineteen medical record administrators(MRAs) of 3 university hospitals participated in coding principal Dx. From August 1, 2001 to August 31, 2001. From each hospital, 10 medical records of patients with high frequency disease were selected randomly. Each 10 medical records were grouped into three(A,B,C). Then, these 30 medical records were given to each MRAs for coding. At the same time questionnaire was given to each of them. Questions were to prove how they decide and code the principal diagnosis among many current diagnoses ; how they decide and code the principal diagnosis when day see irrelevant diagnosis recorded as the principal diagnosis in medical record, when only tentative diagnoses were recorded without final diagnosis, and when different diagnoses were recorded in different sheets of same record. Agreement of coding among 3 hospitals were compared and survey results were analysed with SAS 6.12. Results : Agreement of coding was found in medical records 5-6 of each 10 medical records. Causes of disagreement were as follows. Difference of clinician’s opinion from each hospital; mixed use of guideline from KCD-3 and guideline from DRG; difference in 4th digit classification according to the absence of pathology report in the medical record; difference of abbreviations among hospitals. 57.9% of decided principal diagnosis after consulting to KCD-3 guideline. When there were difficulties in determining the principal diagnosis, 42.1% of MRAs decided principal diagnosis after discussion with the physician, 26.3% after discussion with fellow MRAs. Conclusion : There were differences in coding among hospitals. To minimize the difference, we suggest the development of disease-specific guidelines for coding in addition to the current general guideline such as KCD-3. To do this, Coding Clinic which can produce guidelines is needed.

So, J-M. Han, S-M. S대, J-h. Comparison of the Kinematic Variables int he Badminton Smash Motion. Korean Journal of Sport Biomechanics, Vol. 13, No. 2, pp. 65-74. The purpose of this study was to analyze Kinematic variables in the badminton smash motion through 3-dimensional image analysis. The kinematic variables were velocity of joints in upper limbs, the angle of wrist in the impact, and the angular velocity of the top of racket head. The smash motions of four male badminton players in H University and four male students at department of the physical education in K University who were not majoring in badminton were analyzed kinematically and the attained conclusions were as follow. 1. The velocity of segments in upper limbs of the unskilled group was faster than that of the skilled group. The movement pattern was fast back swing-slow impact moment-fast follow through in the unskilled group, but slow back swing-fast impact moment-slow follow through in the skilled group. 2. As the BS phases, the velocity of segment in right shoulder was different significantly between groups. Right elbow and right wrist segments, velocity of racket head was different significantly between groups(p<.05) by IP phases. As the FT phases, there was no significant difference. 3. The angle of right wrist at the impact, the angle of dorsi flexion and the angle of palm flexion in aspect were shown that the skilled group was higher that unskilled group. There was no significant difference. 4. The velocity of racket head was shown that the unskilled group has fast velocity, but the angle velocity was shown the unskilled group has slow. 5. The angle velocity of racket head in aspect were no significant difference between groups, but maximal angle velocity was different significantly between groups(p<.05).

This study was carried to develop of anaerobic reactor to be able to maximize the organic removal efficiency using laboratory-scale anaerobic filter. The ceramic tube and pall ring media were tested for the applicability as packing media of anaerobic filter for the treatment of a dairy waste. This study was conducted to determine the anaerobic treatability of a dairy waste, and investigate the effects of ceramic tube and pall ring media. Anaerobic filters were packed with packing volume of 65% of total working volume. When treating a dairy waste, the organic removal efficiency of anaerobic filter packed with pall rings was a little higher than that of anaerobic filter packed with ceramic tubes. This was because the reactor packed with ceramic tube had clogging problems and substrate transfer limitations. It seemed that the reactor packed with ceramic tubes had uneven packing due to structural characteristics. The COD removals of ceramic tube and pall ring anaerobic filters were greater than about 91% and 94%, respectively, at organic loading rate lower than 5kgCOD/㎥/d. The COD removals of both reactors decreased to 80% with organic loading rate of 10kgCOD/㎥/d. Biomass capture and solid-liquid-gas separation efficiency seemed to vary with the type of media.

To evaluate the clinical efficacy of ciprofloxacin (CFX) on treatment of the pigs with respiratory diseases or diarrhea, CFX at various dosages were administered intramuscularly to the diseased pigs selected from the pig farms located in Chungnam province. One hundreds and fourteen heads of pigs with respiratory diseases were divided into five groups and CFX at 0.25, 0.5, 1.0 ( = 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were found 31.8%, 73.9%, 91.3% and 92.0%, respectively, being higher than that of the untreated control group (19.0%). The mortality of the treated groups were 0%, that is lower than that of the control (9.5%). Seven kinds of bacteria were isolated from the respiratory organs of 86 pigs, and 34 (39.5%) of 86 pigs showed the complicated infection. In analyzing by the pigs infected with a single pathogen as P. multocida, A. pleuropneumonia, Staphylclcoccus spp. or Mycoplasma spp., the recovery rates were 0∼66.6% at 0.25 dose. 66.6∼100% at 0.5 dose and 100% in all of 4 pathogens at 1.0 to 2.0 doses. At 0.25 dosage the pigs infected with A. pleuropneumonia showed the lowest recovery rate. One hundreds and twenty two heads of pigs with diarrhea were divided into five groups and CFX at 0.25, 0.5, 1.0 ( = 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were 29.1%, 40.0%, 80.0% and 88.0%, respectively. The mortality of the treated groups were 0-8.3%, being much lower than that of the control. Four kinds of bacteria were isolated from the fecal specimens of 94 pigs, and 84 (89.0%) of 94 pigs showed the complicated infection.

A typical metachromatic dye, methylene blue(MB), has been found not to associate in ethanol, ethylene glycol, glycerol and 80 wt.% dioxane. The absorption spectra observed in the various kind of organic solvents are in good agreement with the calculated monomer spectra in both the shape and the absorption intensity. These results suggest that the water molecules play an important role in self-association of the dye molecules in aqueous solution. In this study, the changes in intensity and frequency shift of absorption spectra of MB are observed in the mixtures of water and organic solvents with the change in wt.% organic solvent. The discussions are made both upon the change in intensity and the frequency shift. The intensity changes are attributed to the change in the degree of association and the frequency shift is explained in terms of the interaction between the energy states of the MB molecules and the solvent polarity.
