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.

The objective of this study is to predict the high risk group of coronary artery disease from body mass index, blood pressure, fasting blood sugar and serum lipids level using the method of discriminant analysis. Variables with significant difference between coronary artery disease group and normal group were HDS-C, LDL-C/HDL-C, LDL-C, and TG. But the acuity did not exceed 70% in any single variable. As the results of discriminant analysis, statistically significant discriminant variables were HDL-C, T-chol, FBS and TG. The discriminant equation was(Y) = -0.06759(HDL-C) + 0.01498(T-chol),+0.01923(FBS) - 0.01421(TG) + 0.5187, and the overall discriminant power using the above 4 variables was 79.3%

일반적으로 분할은 그래프 정보를 이용하여 이루어졌으나 논리 정보의 유용성을 보이기 위한 여러 방법들도 제안되었다. 본 논문에서는 분할된 회로의 절단집합에서, 절단선을 두번 이상 지나는 경로는 개선이 가능하다고 가정하고, 선택된 경로에 논리적 정보를 이용하여 변환함으로써 절단 집합의 크기를 줄일 수 있음을 보이고 있다. 잘 알려진 FM 알고리즘을 이용하여 초기분할을 만들고, 논리정보를 이용하여 선택된 개선 가능 경로를 기능적으로 동일한 회로로 변환하였다. 실험 결과에 따르면, 제안 알고리즘은 약 15%의 절단 집합 축소를 보여준다. Generally, graph information is used for partitioning but, various partitioning method have been proposed to show availability of logic information of circuit. In this paper, we suggest that the path to go through a cut-line more than twice can be improved and show that the size of cut-set is reduced by decomposing the path using logic information. First, we perform initial partitioning for a given circuit using FM algorithm. and then transform into the functionally equivalent circuit for the selected improbable path using logic information. This partitioning algorithm using logic information shows 15% reduction of cut-set size compared to FM algorithm.

There are many kinds of treatment method to control allergic rhinitis, chronic hypertrophic rhinitis and vasomotor rhinitis, but proper management remains in controversy. Since the introduction of CO₂laser surgery to the inferior turbinate, it has been developed for proper clinical uses. A defocused CO₂laser beam is used to vaporize the mucosa of the inferior turbinate, based on the assumption that the allergic reaction and mucosal swelling can be inhibited by causing scar tissue formation in the submucosa of turbinate. 50 of 81 patients with allergic rhinitis, chronic hypertrophic rhinitis and vasomotor rhinitis who were treated by a defocused CO₂surgery from April 1, 1996 to February 30, 1998 were followed for this study. After nasal CO₂laser surgery, nasal obstruction, watery rhinorrhea, sneezing and itching sensation were significantly improved. This laser surgery has clear advantages such as lack of pain and bleeding and can be done under the surface anesthesia as an outpatient procedure.

Multilayer coatings consisting of very thin layers of nitride materials deposited by magnetron sputtering (sometimes called superlattices) exhibit hardnesses over 50 GPa, much higher than that of single layers. Several explanations for this hardness increase have been proposed, including dislocation blocking by layer interfaces, Hall- Petch strengthening, strain effects at layer interfaces, and the supermodulus effect. Among these, dislocation blocking has been generally accepted as a dominant factor in large hardness enhancement. However, the interface between two materials consisting of multilayers is broadened due to interdiffusion. The magnitude of hardness enhancement by the interface has not yet been quantified for real systems. In this study, the concept of composite hardness is introduced to quantify the interface-related hardness enhancement. We suggest a composite hardness equation and quantifythe magnitude of hardness increase by using an equation based on the interface hardness and the interface thickness derived by comparing results derived from this equation and those determined in nanoindentation tests. Three multilayer systems, such as TiN/VN, TiN/NbN and CrN/NbN were used in the equation.

To obtain some results of the rate of abnormal keton body in urin of dairy animals by age calving rate, milk yield and some feeding and management condition, 104 cows and 107 dairy goats were investigated. And the results obtained were summerized as follows. 1. From about 23.1% of cows and 39.3% goats, abonormal condition of keton body in urine dectated. 2. The rate of abnormal keton bodies possession were lower at the age of 1∼4 but higher at the age of 4∼11. 3. From the calving animals, the highest rate of keton body were detected but the lowest from first and ninths calving animals. 4. The cows than 20kg milking per day and the goats 3∼4kg milking were higher but the cows below 10kg milking and the goods 1∼2kg milking were lower. 5. Under bad feeding and management condition, the amount keton bodies in urine of animals were increased much.

Locally recurrent rectal cancer is a difficult clinical problem. Local recurrence following treatment for rectal cancer is a major cause of morbidity and mortality. The reported range of local recurrence rates following surgical treatment for rectal cancer has varied from 4% to 50%. We retrospectively reviewed the charts of 142 rectal cancer patients from January 1991 to December 1999. Analysis of patients factors included age, gender, type of surgery, and adjuvant therapy. Tumors were assessed for level, stage, and grade. Local recurrence and distant metastases were also documented. Variables influencing local recurrence in this group were identified and disease-free survival is determined. Of the 142 patients(74 males, 68 females; mean age 62.6 years), 137 consecutive patients operated on for rectal cancer and followed up to December 2000 (range 23-118months) were analyzed. Local recurrence rate was 18.3%. Age and sex of patients, type of surgery, location of tumor in the rectum, size, morphology and grading of the tumor were all unrelated to the event under investigation. At Cox regression, the Dukes stage and the postoperative radiotherapy were the only independent prognostic factors for local recurrence, and Dukes stage (Hazard ratio=2.89, p<0.001) and local recurrence (Hazard ratio=3.31, p<0.01) were the only independent factors associated with improved survival.
