Background : This study was performed to determine the cut-off value and the predictability of symptomatic human cytomegalovirus (HCMV) infection according to the peak value of HCMV antigenemia assay in kidney transplant recipients. Materials and Methods : We reviewed the results of HCMV antigenemia assay (Chemicon, CA, USA) in patients who received kidney transplantation at our institution from May 2003 through May 2008, and investigated the existence and the type of HCMV infection by the medical record review. Patients who underwent the test only once during the episode or those who received ganciclovir for more than 48hrs before the test were excluded. The receiver-operator characteristic curve was drawn and the point showing maximum likelihood ratio (LR) was chosen as the cut-off value of symptomatic HCMV infection. Results : A total of 689 episodes were screened and 134 episodes were enrolled. Thirty-three (24.6%) episodes were symptomatic HCMV infection, 23 (17.2%) episodes were associated with HCMV syndrome, and 10 (7.5%) episodes were tissue-invasive diseases. The maximum LR was 7.5 (95% confidence interval, 4.014.2) and the cut-off value was 29.5 cells/200,000 WBC. The sensitivity, specificity, Positive predictive value, and negative predictive value were 66.7%, 91.1%, 71.0%, and 89.3%, respectively. Conclusions : The cut-off value of symptomatic HCMV infection by the peak value of HCMV antigenemia assay in our study was similar with previous results, although the sensitivity was relatively low.

Samples of blood were taken from 104 horses in Chejudo and the blood grouping investigations were carried out , using 17 types of Stormont's standard reagents : A_(1), A', Z , ZZ_(2), C, K, P, Q, R, S, U_(2), X, N_(1), E_(2), H, J and T_(1) types. Blood samples were also taken form 37 horses in Hok-kaido and were examined for comparison. E_(2), H, J and T_(1) 4 types among all of erythrocyte types of horses were detected by agglutinative reaction and A_(1), A', Z, ZZ_(2), C, K, P, Q, R, S, U_(2), X and N_(1), 13 types were detected by hemolytic reaction and the results obtained were summarized as follows. 1. Over 80% of erythrocyte types of horses in Cheludo were U_(2), X, ZZ_(2), and A_(1) 4 types and over 50% types were T_(1), C, E_(2) and N_(1), 4 types and the phenotypes frequencies of others were low percentage comparatively less than 50%. H and A' types were lowest of 15.38% respectively. 2. Four types of U_(2), X, ZZ_(2) and A_(1) were showed high phenotype frequencies in erythrocyte types of both species of horses and also high requencies in horses of Hokkaido were R type of 97.29% but showed the differences of 42.30% in horses of Chejudo. 3. The second, higher types of phenotype frequencies wire C, E2, N1 and R types and t1 types was high of 77.88% comparatively in horses of Chejudo, but they were merely 37.83% in horses of Hokkaido. H types was low type of 15.38% in horses of Chejudo but it was nnoe showed entirely in horses of Hokkaido, J type showed was 43.26% in horses of Chejudo but it was none showed in horses of Hokkaido. The other hand, a' type as 81.08% in horses of Hokkaido but it was 15.38% of most low frequencies in horses of Chejudo. 4. Seventeen blood types were all showed in horses of Chejudo but 2 types of H, J were not showed entirely i horses of Hokkaido. Therefore, it was confirmed that the differences in phenotype frequencies of erythrocytes among of the both species of horses.

As an automobile fuel, LPG has many environmental advantages compared to gasoline or diesel. However, current LPG engine which is provided with LPG fuel as gas form has lower power and worse fuel efficiency than gasoline engine. These problems of low power and bad fuel efficiency come from lower volumetric efficiency. Also there is a new rising problem of high failure ratio in an engine emission test. Although there are many factors which affect engine performance of exhaust gas emission, one believes that the fact that ECM of gasoline engine is used for LPG engine when retrofitting gasoline engine to LPG engine is one of the main problems, which lower engine power and emit more noxious gas due to wrong ignition timing. To solve these problems, one studied the effects of ignition timing on the exhaust gas to find out the optimum condition of ignition timing. The experimental results show that noxious exhaust gas is reduced and engine power is increased if the optimum control of ignition timing is applied in accordance to the revolution speed of engine.

To knonl the effect of H.C.G on Motor function in pregnanty, 10 pregnant women and nursing mothers at 3 hospitals in choon choen City were tested as sbjects. These analyzed results are as follows. 1.H.C.G. normal state was 50.9%, but H.C.G on pregnant state at 10 months showed 48.2%. So the H.C.G at pregnant state was lower than at normal state. 2.Balance function at Pregnant state was higher than normal state (9.42 times in nomal state,4.43 times in pregnant state at 9 months) 3.Agility function in normal state was 10.3 Cm, and in pregnant state at 8 months of that was 17.4 Cm. Agility function and pregnant state was lower than at normal state. 4.Correlationships between H.C.G and Balance in normal and pregnant state skowed certain correlation coffecients, and the defference of each arithmetic man showed significant. 5.Correlationships between H.C.G and Agility in normal arid pregnant state were not presented.

The subjective environmental indicators were applied to study the resident environmental indicators for the newly developing residential areas in the city of Suwon. The selected factors for the subjective resident environmental indicators were evaluate using the individual satisfaction degree with the weighing factors worked out from individual residents. The weighing factors used for the subjective environmental indicators were first standardized. The results from this research work show that the factors which are considered as important by the Suwon residents so are the residents of other cities. All computations were carried out by the SAS statistical program. A provincial government can fully utilize these results for the plan of setting priority as a practical use for a regional environmental management program. Then, it would be expected that the government can get good agreement and response with residents for developing a pleasant residential environment because of their participation.

안덕선,한승규,구상환,한재식 大韓成形外科學會 1995 Archives of Plastic Surgery Vol.22 No.5

This retrospective study includes consecutive 54 Blow-out fractures patients to whom underwent surgical correction (June 1988-Feb 1994) and 25 patients have been followed up for more than 1 year. The diagnoses of blow out fracture was made through a physical examination, X-ray, and CT and It is confirmed at the time of surgery. Initial physical examination revealed limitation of ocular motion and diplopia in all 25 patients, and infraorbial nerve hypoestesia in 18 patients, and enophthalmos in 1 patient. There were 27 patients who had associated ocular injury including subconjunctival hemorrhage, angle recession and iris sphincter damage. and the three most common causes of blow-out fractures were traffic accident, fist blow and fall down. The latent period between injury and surgical intervention was average of 8 days and the longest time was 12 days. Surgical approach was done by subciliary incision and autogenous (10 cases) or synthetic (37 cases) implant was inserted over the fracture site in 47 patients. The floor and medial wall of orbit were the frequent site of blow-out fracture in this retrospective study. Among 28 patients who have been followed up for more than 1 year, 3 patients had diplopia persistently which developed only when the patient was tired, and 5 patients had late developed enophthalmos. We found that early surgical reduction of blow-out fracture with implant gave a favorable results without any significant complications.
