Although Herpes Simplex Virus (HSV) infection is one of the most common infectious diseases, its two main laboratory diagnostic methods-Tzanck smear is a simple, inexpensive and rapid method, but it shows relatively low positivity. Similarly, the viralculture is the most accurate and definitive method, but it is expensive and relatively time-consuming test. There is a demand for more practical laboratory diagnostic methods for cutaneous herpes simplex infections. The purpose of this study is to examine the effectiveness of the indirect immunofluorescence (IIF) staining with monoclonal antibodies, which is suggested as a practical method. For the study, 103 patients suspected HSV infection were sampled at the Department of Dermatology in Hanyang University Hospital from March 1987 to July 1990. In the 60 specimens for Tzanck smear and viral culture, Tzanck smear was 35(58.3%) positivities, and viral culture was 56(93.3%) positivities(p〈0.05). In the 43 specimens for viral culture and IIF staining, viral culture was 40(93%) positivities and IIF staining was 37(86%) positivities(p〉0.05). In the 25 specimens, which viral culture was positivities, IIF staining showed 22(88%) positivities and Tzanck smear was 16(64%) positivities(p〈0.05). In summary, the result of Tzanck smear showed relatively high correlation to the results of IIF staining and viral culture. However, the result of IIF staining showed a significant agreement with the result of viral culture. It is suggested that the IIF staining with monoclonal antibodies is a simple, inexpensive, but accurate and relatively rapid method for the diagnosis of cutaneous HSV infections.

High density plasma deposition system was organized using electron cyclotron resonance source, and its plasma properties were measured by using the Langmuir probe method. The ECR microwave plasma conditions could be controlled by means of mass flow controller and ECR microwave power according to the vacuum pressure of 2.3×10^-5 Torr to 5.2×10^-2 Torr. The ion density was increased with an increase of gas flow rate, and a decrease of the distance between ECR source and substrates. The electron temperatures were decreased with an increase of gas flow rate, and a decrease of the distance between ECR source and substrates. The estimated plasma potential was from 27.0V to 31.5V

Pole Placement Control has been well establish in its theory. However, its practice value is yet to be appreciated in most industries. This paper presents an account in which the control strategy is run on the hydraulic motor. Using the input and output data from actual system, estimation of the model parameters are obtained by a function ARMAX(Autoregressive Moving Average with am exogenous signal) in Matlab and controller synthesis is achieved by a Pole placement control. Estimation system from a ARMAX is defined by third order and application of Pole placement control technique will be provide not only stability but also good performance for motion of hydraulic motor in any operation condition.

The purpose of this research was to investigate the present state of continual upbringing of school elite sports, athletic facilities, university and business sports teams and the achievements of the 78th National Athletic Competition of Ulsan city and find out how to activate the elite sports in Ulsan base on the investigations. The results are as follows; 1) In the 78th National athletic competition, Ulsan was ranked the lowest, scoring 10,868points, 1.68% of all the scores. 2) Athletic facilities of Ulsan are the worst of the 16 cities and provinces. 3) It is very necessary in Ulsan to continuosly train and develop teams. In particular, it is most required to concentrate on improving field and track competition, swimming, western style archery, gymnastics, cycling, weight-lifting, canoe and shooting.

Numerous evidences support the pathogenesis that M. pneumonias pneumonia is associated with cell-mediat-ed immune reaction. We report 2 cases of severe M. pneumoniae pneumonia in previously healthy sisters, who were both admitted during an epidemic of M. pneumoniae pneumonia. The elder sister, who was 16 years old, was admitted with M. pneumoniae pneumonia. She showed no response to treatment with clarithroycin and levo-floxacin, and eventually progressed to severe ARDS, requiring mechanical ventilation. After treatment with hydrocortisone (200 mg/day), there were rapid improvements in clinical manifestations and chest radiographic findings. The younger sister, who was 14 years old, was admitted 10 days later, Presenting with fever but no pneumonic lesions on chest radiograph. Just like her sister, the infection showed no response to clarithromycin. Fever persisted and pneumonic consolidation with mild pleural effusion was noticed in the left lower lobe on the 5th hospital-day. After treatment with oral prednisolone (1 mg/kg), she showed rapid defervescence and on the 8th hospital day, no pneumonic lesions were detectable on chest radiograph. Given the fact that the pathogenesis of pneumonia and extrapulmonary manifestations in M. pneumoniae infection is immune-mediated, an immuno-suppressive therapy would be validated for selected patients with M. pneumoniae infections.

In this paper the rates of two-and three-dimensional scattering are calculated in pseudomorphic ??/??/GaAs HEMT heterostructure systems. The electronic states and wave functions in the square quantum well are determined numerically by the self-consistent solution of Poisson's and Schrodinger's equations. The wave functions and energy levels obtained are used to calculate the major two-dimensional scattering rates in this structure. Polar optical- phonon and acoustic- phonon, piezoelectric, ionized impurity and alloy scattering rates are considered for the first two subbands. This results are compared to the three-dimensional scattering rates also calculated using by the triangular approximation of quantum well in the same structure.

Carbon monoxide is generated from the incomplete combustion of carbon-containing materials. Carbon monoxide cause muscle necrosis leading to myoglobinuria and acute renal failure. The hyperbaric oxygen exposure is increased production of active free radicals. Free radicals which promoted peroxidation of unsaturated fatty acids may destroy essential cellular components and itself cytotoxic materials. Superoxide dismutase, one of the protective mechanisms against tissue damage, catalyzed the dismutation of superoxide anion to less toxic product. The author performs the present study to investigate on Mn-SOD and Cu, Zn-SOD immunoreactivities in kidney and heart carbon monoxide (CO) and hyperbaric oxygen (HBO) exposure. The animals were divided CO exposure group, air release after CO exposure group, HBO exposure group and, CO and HBO exposure group. The specimen were sectioned in 16㎛ with cryostate. The Mn-SOD and CuZn-SOD immunohistochemistry was performed in renal corpuscle, proximal and distal convoluted tubules of kidney and, in sarcoplasm and sarcolemma of heart muscle. The results obtained were as follows: 1. The immunoreactivity of Mn-SOD were increased in renal corpuscles and distal convoluted tubules, were similar to control group in proximal convoluted tubules. 2. The immunoreactivity of Cu, Zn-SOD were increased than that of control group in renal corpuscles and distal convoluted tubules, were same that of the control group in proximal convouted tubules. 3. The immunoreactivity of Mn-SOD were increased at all experimental group of sarcoplasms of heart muscle. 4. The immunoreactivity of Cu,Zn-SOD were increased than that of control group in sarcolemma of heart muscle. These results suggest that the immunoreactivity of SOD after CO or HBO exposure is greatly increased in kidney and heart.
