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.

Background : In recent years, gonorrhea has been pandemic and remains one of the most common 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 Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

황준필 ( Hwang Jun Pil ),김기범 ( Kim Ki Beom ),안기용 ( Ann Ki Yong ) 한국구조물진단유지관리공학회 2009 한국구조물진단유지관리공학회 학술발표대회 논문집 Vol.13 No.2
For the characteristics of the concrete using Hwang-Toh aggregate, thermal Insulation capacity test, absorption capacity of heavy metals several test were performed. The study found that the Hwang-Toh concrete could improved the characteristics of conventional normal concrete. The Hwang-Toh concrete shows 67.7% lower thermal conductivity than normal concrete, so it shows good thermal insulation capacity. And the leaching test results showed that 96% of heavy metals such as Pb, Zn, Mn were absorbed by the Hwang-Toh concrete.

불연속 지형을 지나는 천수 흐름을 해석할 수 있는 Hwang의 기법이 채택된 수치 모의를 댐 붕괴 흐름에 의한 직립 홍수터의 범람 실험과 비교하였다. 모의 결과는 저수지, 저수로, 홍수터로 이루어진 실험 수로에서 측정한 결과와 잘 일치하였다. 특히, 댐 붕괴 흐름이 직립 홍수터로 차고 빠지는 과정이 잘 모의되었다. 흐름 저항의 종류에 따른 모의 결과의 차이는 미미하였다. 이 연구를 바탕으로 도심 하천의 범람 예측에서 정확도를 높일 수 있을 것으로 기대된다. Numerical simulation with Hwang’s scheme, which can analyze shallow-water flow over discontinuous topography, was compared with a laboratory experiment of flooding on a perpendicular floodplain with dam-break flows. The simulation results were in good agreement with the results measured in an experimental flume with a reservoir, channel, and floodplain. The wetting and drying process on a perpendicular floodplain with a dam-break flow was particularly well simulated. The difference in simulation results according to the type of flow resistance was insignificant. The results of this study are expected to improve the accuracy of predicting inundation in urban rivers.

연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

N/A Most authorities agree the higher incidence of gallstones among diabetic patient. Although many reports on gallstones or diabetes mellitus have been published, and actual correlation between gallstones and diabetes mellitus remains obscure. The purpose of this reports is to know the incidence of gallstone in diabetics and of diabetics in the patients with gallstone. Authors studied prospectively and clinically the diabetics in a group of 173 patients with gallstones and gallstone in a group of 98 diabetic patients who were admitted to Yonsei University Yong-Dong Hospital for the same period of April 1983 to May 1984. The results obtained are summarized as follow: The incidence of gallstone to general admission patients is 1.5% and the prevalence of diabetes mellitus to total in-patients is 0.8% The gallstone was found in 11.0% of diabetics and were diabetic 19.4% of patients with gallstones. The age of peak incidence of gallstones is 5th decade and female was more prevalent than male with the ratio of 1.37:1. The age of peak incidence of diabetes mellitus is 6 th decade and female is less prevalent with the ratio of 0.72:l.3, The most common characteristic finding of patients of gallstones with diabetes mellitus is symptomless(42.1%)4, There is no significant difference in serum levels of cholesterol and triglyceride between diabetic and non-diabetic groups or with and without gallstones. 5. Comparative study on location of stones revealed, 72.8% in gallbladder only, 12.7% in common bile duct only, 4. 6% in intrahepatic duct only, and remainders in multiple site. There is no significant difference in terms of location of stone between diabetic and nondiabetic group.

The prognosis of oral malignant melanoma is poor compared with cutaneous melanoma. It may be related to the difficulty of wide enough resection, the early hematogenous matastases, higher stage at initial diagnosis, tendency to growth vertically. In the view of histological differences between oral mucosa and skin, it is impossible use Clark’s and Breslow’s classifications for prognosis. The great problem is that there is still no consensus on the treatment due to rarity. Because data collection from case reports is considered to be the best source of information and should be pooled to anlalyze key determinants of outcome, We reported on 6 cases of primary malignant melanoma of the oral cavity which were diagnosed and treated in Pusan National University Hospital recently and reviewed the literature. Immunohistochemical study on S100 Protein, GP 100 (HMB-45) with biopsy was usable to confirm the melanoma. Neck dissection including wide excision is recommended if lymph node involvement is suspected. Additionally, adjuvant chemotherapy could be supporting therapy.

The purpose of this study was to analyzed the aerobic capacity of disability· able-bodied wheelchair basketball players. Cardiorespiratory parameters were measured during graded maximal exercise test. Exercise time, HRpeak, oxygen uptake(VO_2, L·min^-1, ml·min^-1·kg^-1), carbon dioxide production(VCO_2, L·min^-1), ventilation(L·min^-1) were examined in disability national elite male wheelchair basketball at letes(DA, N = 10), able-bodied wheelchair basketball athletes(AA, N = 10). All data were expressed in means and standard deviation. Exercise time, HRpeak, oxygen uptake, carbon dioxide production, ventilation were not different between groups. In conclusion, aerobic capacity of disability national elite male wheelchair basketball athletes is the same able-bodied wheelchair basketball athletes. These finding suggest that chronic wheelchair basketball training produce local adaptations in the functional upper body musculature.
