We performed a prospective study of 303 transferred patients(21.8%) to our emergency center from their initially visited hospitals for 6 months from July 1992 to December 1992. The results were as followed; 1) One thousand three hundred eighty eight trauma patients were visited to the emergency center for 6 months. Among the transferred 303 patients, 99 cases were due to traffic accident, 72 cases were falling down injury, and 62 cases were blunt trauma injury. 2) In terms of injury severity score, patients who were directly admitted to our emergency center had a score of 2.51±5.39, while those who were transferred had score 4.53±6.24. The scores were statistically significant. The combined patient population had a injury severity score of 2.95±5.64. There was no statistical difference between the severely injured patient group (ISS>=16) and the less severely injured patient group(ISS<16). 3) Among the patients who were transferred to our emergency center, those who were discharged from initially visited hospitals within 1 hour had ISS of 3.56±5.70, while those were discharged over 24 hours had ISS of 5.27±4.37. But there was no statistical difference between two groups. 4) Of the 303 patients who were transferred to our emergency center, 265 were from Seoul and Kyung-Gi Do and 38 were from various other regions. Among the transferred patients who were brought to emergency center after at least 24 hours of their accidents, 30 patients were elective transfer(patients` need)while 25 were not-elective transfer(further evaluation or proper treatment). Within this group, 3 were severely injured patients, of them two expired. 5) Severely injured patients(ISS>=16) occupied only 15 cases(4%)among 303 patients who were transferred to the emergency center. Among them 10 patients expried at the emergency center. The causes of death were irreversible shock in 4 cases, intracranial problem in 4 cases and hypoxia due to airway obstuction in 2 cases. In the cases of transferred patients there were no interhospital communi-cation before transfer. From the above information, we conclude that the tansferred patients to our emergency center had a higher ISS than of those who directly visited to the center. For effective treatment and higher survival rate, interhospital communication, presence of medical personel during transfer, performing of basic life support prior to transfer and strict limitations for transfer except critically-ill patients are important.

This paper reports an investigaion for the health status of subway workers in the 67 subway stations in the Seoul area during from September 15th to Nobimber 15th, 2002 . Prevalence of subuective complaints was surveyed of 400 subway workers applied by a general health questionnaire-the Todai Health index(THI). The basic tool employed in this present study was the THI which is modified Comell Medical Index(CMI) and was developed by Tokyo University Research Team in Japan, and had been used to evaluate manufacturing workers, iron workers and other workers by Kim(1979), Chung(1982), Lym(1987), Lee(1996) in Korea. The results were summarized as follows; 1. The physical and psychological complaints were much higher in the 20~29 age group than other age groups. 2. The physical and psychological complaints showed a high tendency of increased incidence in all items as length of service decreased, and the 3~5 years group was higher than less 1 year group with regard to the symptoms of Digestive(C), Aggressiveness(F), Nervousness(E). 3. The physical and psychological complaints showed much higher tendency in the station staff(S?S) group than other groups. 4. The physical and psychological complaints showed much higher tendency in the under station(Un.S) and upper station (Un.S) groups than other groups. 5. The responses of physical and psychological complaints by monthly pay showed much higher tendency in he income of 10.1~1.50 millions won group than other groups. 6. The responses of physical and psychological complaints by smoker or non-smoker showed much higher tendency in the smoker group than non-smoker group. Therefore, it can be concluded that the worker of subway studied was perceived as acceptable the importance of health status, and suggested that the goverment of related subway need to be effort to control the health of subway workers in environment of indoor.

Object : This study was conducted as part of the national project to standardize stroke diagnosis in Korean medicine. In this study, we aimed to evaluate the characteristics of acute stroke between heat pattern group and cold pattern group. Methods : We recruited stroke patients from 5 universities(Kyung-Hee University oriental medical center, Kyung-Hee University East-West Neo medical center, Kyungwon university lncheon oriental medical center, Kyungwon university Songpa oriental medical center and DongGuk university llsan oriental medical center) from April, 2007 until February, 2010. We diagnosed them and selected 463 heat pattern patients and 182 cold pattern patients. Results : We find that the risk factor of smoking, alcohol, diet(prefer to meat) are more associated with the heat pattern group. On the other hand, inflammation history in recent 3 months and diet(prefer to sea food) are more associated with the cold pattern group. RBC, Hg, Hct, TG, CK and Cl are more related to the heat pattern group. CPT, total cholesterol and HDL are more related to the cold pattern group. Tae-eum type takes high distribution of the heat pattern group, and So-eum type takes high distribution of the cold pattern group. Conclusions : This study provides evidence that the heat pattern group have more risk factor than the cold pattern group.

This experiment was done to investigate the leaching and adsorption properties of heavy metals on porphyry. The comparison with respect to the leachability of heavy metals from porphyry between the Korea Standard Leaching Test (KSLT) and the Toxicity Characteristic Leaching Procedure (TCLP) was carried out. The fractional composition of leachate and the total concentration of heavy metal of porphyry were studied through Sequential Extraction Procedure (SEP) and EPA Method 3050. Adsorption experiment of porphyry has pointed out that the optimum dosage of porphyry for 50ppm Pb was over 10g/L, the effective particle size for absorption was below 200 mesh and the optimum pH was about 7. From the Freundlich' adsorption equation, l/n was 1.0722, and k was 0.0041. After adsorption, the fractional composition of Pb was changed. The exchangeable, carbonate, reducible fractions were increased, and the organic fraction was not changed, and the residual fraction was decreased.

Background: Inducible MLS_(B) (macrolide-lincosamide-streptogramin B) resistance in staphylococci is not detected by standard susceptibility test methods. Failure to identify inducible MLS_(B) resistance may lead to clinical failure during clindamycin therapy. We determined the prevalence of inducible MLS_(B) resistance in erythromycin-resistant staphylococcal isolates. Materials and Methods: We evaluated all 2,792 non-duplicate staphylococcal strains: 1,402 Staphylococcus aureus and 1,390 coagulase-negative staphylococci (CoNS) isolated from May 2008-June 2009 at one-unoversity hospital. Testing for inducible MLS_(B) was accomplished by the disk approximation test (D-test) in accordance with the recommendations of the Clinical and Laboratory Standards Institute (CLSI). Results: Of the 2,792 staphylococcal isolates, 892 S. aureus isolates and 740 CoNS isolates were resistant to erythromycin. Among the 892 erythromycin-resistant S. aureus isolates, the overall prevalence of inducible MLS_(B) was 21.3% (16.2% of MRSA and 76.3% of methicillin-susceptible S. aureus). Among the 740 erythromycinresistant CoNS isolates, the overall prevalence of inducible MLS_(B) was 16.5% (16.0% of methicillin-resistant CoNS and 18.7% of methicillin-susceptible CoNS). The D-test was positive in 88.8% of S. aureus and 28.4% of CoNS isolates, which were erythromycin-resistant and clindamycin-susceptible. Conclusions: There are some variations in the prevalence of inducible MLS_(B) resistance in clinical staphylococcal isolates. It is important that clinical laboratories report inducible MLS_(B) resistance for erythromycin-resistant and clindamycinsusceptible staphylococcal isolates.

From ride share aspect, Korean taxis are functioning as public transit. However, taxi-operators are generating social problems on issuing taxi licenses every year, because there is no reasonable method for estimating adequate number of taxis in a city. Thus, a method for estimating adequate number of taxis was developed in this study, the method consists of three criteria; one is the criterion based on optimal taxis' occupancy rate considering optimal waiting time of passengers, the optimal income of operators, and working hours of taxi divers, another is criterion on taxi-passenger chane, the other is the criterion on traffic conditions. Also, a new observation method of taxis' occupancy rate was suggested. In this study, Chinhae was selected as the study city. Followings are the results of this study. First, by using the new observation method of taxis' occupancy rate based on taxi traffic count reliable occupancy data could be collected with low expenses. Second, the results applying the model suggested in this study to Chinhae showed that preset number of axis is adequate and the results matched well with the real situation of Chinhae.

The right-turning adjustment factor is one of major factors to estimate saturation flow rate of signalized intersections. The right-turning adjustment factor represents the influence of right flow to the through flow at signalized intersections. The Korea Highway Capacity Manual has some problems to estimate the right-turning adjustment factor. This study suggested equations to estimate the right-turn adjustment factor at signalized intersections using physical characteristics, right-turning traffic volume during red signal and right-turn impossible time rate by crosswalk pedestrians based on field observation. The conclusions of this study could be summarized. 1. The right-turning adjustment factors of the exclusive right-turn lane are different by physical type of intersection. 2. The right-turn impossible time rate by crosswalk pedestrians is estimated using standard values by width of crosswalk. 3. The right-turning traffic volumes during red signals are estimated by the through traffic per lane.
