Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

This study was to investigate the effects on hematological indices and heinz body formation in various intensity, Male Sprague-Dawley rats were randomly divided into the control group, the low-intensity exercise group, nigh-intensity exercise group (n=7 in each group). Animals of the low-intensity exercise groups were put on exercise 30 min per 1 day, 5 days per week for 6-weeks. Animals of the high-intensity exercise groups were put on exercise 120 min per 1 day, 5 days per week for 6-weeks. Red blood cell count (RBC), hemoglobin (Hgb), hematocrit (Hct), mean ceil volume (MCV), mean hemoglobin corpuscular (MCH), mean hemoglobin corpuscular concentration (MCHC) were analyzed in automated hematology analyzer (ABX Hematology MICROS 60) from 10㎕ of whole blood. Erythrocyte morphology were evaluated in super vital (Brilliant cresyl blue stain) stained blood films. In the present results, Hg, MCHC in the high-intensity exercise group was significantly decreased compared with the different exercise intensity and the control group. MCV in the high-intensity exercise group was significantly increased compared with the different exercise intensity end the control group. Heinz body formation in the high-intensity exercise group was significantly increased compared with the different exercise intensity and the control group. In the present study, it can be suggested that intensity of exercise can influence hematological variables and heinz body formation. These findings suggest that high intensity exercise induces oxidative damage to erythrocyte.

본 병원에 내원한 절단된 이하선관 환자 총 20명(남자:10명 여자 10명)중 4명을 제외한 16명에서 추적조사가 가능하였으며 이 중 14명에서 이하선관의 원활한 관통이 이루어졌고 1명에서 관의 폐세기 생겨 2차 수술이 필료 했으며 다른 1명의 경우 농의 배출이 있었으나 항생제 투여와 구강위생등으로 별 다른 문제 없이 치료 되었고 또 1례의 이하선 타석을 치험하여 보고하는 바이다. Due to increasing trend of traffic accident, number of patient has been gradually increased. Facial injury, for its anatomical vulnerability, is most common site of injury and greatly exceeding injuries of other body region in trauma patient. There are occasional report of Stensen`s duct damage accompanying facial injury and much problem can arise when first aid is performed without knowledge of anatomy or concern for patient. Generally, Stensen`s duct located at mid 1/3 portion of line passing through tragus of ear and subnasale, another word, above the masseter muscle. Once deep lacerated wound has occurred in this region, one must suspect damage of Stensen`s duct. Among the 20 patients (Male: 10, Female:10) who have beeb treated at Chonnam National University Hospital for severed Srensen`s duct, 14 cases have obtained favorable result, not counting 4 patients with whom follow-up study was not possible. In unsuccessful cases of two, 1 case required secondary operation due to occurance of ductal stricture. In another case, leakage of pus has been observed but with proper oral care and antibiotic administration, it has been treated withiut any difficulty. Facial nerve injury accompanying Stensen`s duct been frequently observed, buccal branch being the most common site of involvement. Time interval from severance of duct to repairing the duct was 7 to 21 hours on average and time delay of this level has not impose much limit to obtain successful result. Suture material for Dowel, no matter what kind used, has achieved favorable result and time interval of 9 to 21 days given before the removal was long enough to obtain successful operative result without any development of complication. It is generally accepted view that salivary stone is most common disease entity among the salivery glands and ducts, and stone mostly occur in submandibular duct and rarely in Stensen`s duct. We have performed end-to-end anatomosis using a 23 guage polyethylene catheter as a Dowel in severed duct in 20 patients who have been admitted our hospital for cut repair and obtained satisfiable result. In 1 case, we have experienced stone on the Stensen`s duct, therby reporting this case with through reviews of literature.

Digital Watermarking is a research area which aims at hiding secret information in digital multimedia contents such as image, audio, and video. In this paper, we propose a new watermaking method with visually recongnizable pattern into the digital image using wavelet transform, spread spectrum method and multilevel threshold value in considering the wavelet coefficients. The watermark information can be extracted by subtracting wavelet coefficients between the origitnal image and orginal image and the watermarked image. The esperimental results show that the prosposed technique is invisible watermarking and robust to JPEG lossy compression, resizing, masking, and filtering.

Kim,Sang-Yong,Kim,Kae hwan 한국자원식물학회 2002 Plant Resources Vol.5 No.1

Palynological characters such as pollen grain polar axis length (PL), pollen equatorial diameter (ED), colpus length, colpus width, and P/E ratio of six species of Quercus subgenus Lepidobalanus Endl. from Korea were studied. A significant interspecific variation, unequal distances between the species, and various degree of intraspecific variations were found. The taxonomic value of the pollen morphology parameters measured was found to vary according to species. These results suggest a possible relationship between parameters measured and ploidy level of the Quercus species studied.

Chloride ions are considered to be the major cause of steel corrosion in concrete structures exposed to seashore environments and also permeation of chloride is controlled by chloride diffusion. Therefore, the study on chloride diffusion of concrete have been done so far by many researchers. In this study, several factors such as capacity of voltage, time of an electric current, concentration of NaCl solution, water-cement ratio, and temperature of the solution were examined to grasp what influence they were on the chloride ion diffusion properties using the Rapid Chloride Penetration Test(RCPT) by electrophoresis. Also standing on the basis of the such result application possibility of Rapid Chloride Penetration Test(RCPT) used in this study will be evaluated and the basic data on the durability design for the chloride attack will be suggested.
