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.

Objective : This is to report the effectiveness of intraoral distraction osteogenesis for alveolar augmentation in the extremely atrophied alveolar defects and to review the clinical results of the 2 cases. Subjects and Methods : Anterior segmental osteotomy was performed and the trans-oral alveolar distractors(Martin, Germany) were applied in 2 patients with the severe acquired anterior maxillary and mandibular defect. After latent period for 1 week, the osteomized alveolar segments were distracted by 1 ㎜ a day (0.5 ㎜/l turn) for 8 days in case Ⅰ and 0.6 ㎜ a day(0.3 ㎜/l turn) for 10 days in case Ⅱ. The consolidation period was about 8 weeks in each case. Thereafter, 6 titanium threaded implants(Branemark, Restore) were simultaneously installed with removal of distractor. The implants were tested clinically and radiographically. Results : Amounts of acquired alveolar bone were 8 ㎜ in case Ⅰ and 6 ㎜ in case Ⅱ respectively, with the increased width of the ridge crests and soft tissue expansion. Dental implants installated on the augmented alveolar ridges in 8 weeks after distrction were confirmed as in good osseointegration and in good function without any complications. Conclusion : Intraoral distraction osteogenesis can be a good option for alveolar ridge augmentation of the severely atrophied ridges and soft-tissue defects. However, for the better vector control of distracting segments and for anterior esthetics, customized distraction devices could be considered later.

In order to evaluate six formula of T_(c) presented in the facilities criterion of small basin, the water stages were observed on fifteen mountainous small basin in Sanchung county region. The results of six formula compared with the observed data to evaluate T_(c). All basin area were less than 2.25 ㎢. The average basin area was 1.19 ㎢, the average basin length was 1.65 ㎢, the average basin slope was 6.95%, average length and slope of main channel were 1.86 ㎞ and 7%. The average T_(c) was 33.77 minutes and results of six formula showed the changes in average and standard deviation widely. The conclusions obtained in this study are as follows. The time of concentration was influenced basin slope, basin length, basin slope and channel slope consequently but did not affected the shape factor of basin.
??C追跡子法에 依한 柑橘의 糖과 有機酸에 關한 硏究 : Effects of Foliar Application of ?? ??의 葉面處理效果

柑橘(Citrus unshiu Marc.)의 糖, 有機酸 및 아미노酸에 대한 ??의 영향을 보기 위하여 KCI과 K₂SO₄溶液을 葉面處理하고 ?? 를 同化시킨 뒤 ??C로 標識된 同化産物의 徑時的 變化를 3週間 調査하였다. ?? 處理後 1週日間 果實에 轉流된 ??C 同化産物의 比放射能(cpm/㎖)은 ?? 處理區에서 더컸다. 果汁의 糖分劃 放射能은 그 水準과 變化樣相이 ?? 處理間에 差異가 없었지만, 有機酸分劃에 있어서는 ?? 處理後 2週日 以後에 有機酸分劃의 比放射能 減少量이 ?? 處理區에서 더 많았다. 有機酸分劃의 比放射能에 對한 糖分劃比放射能의 比率이 SO?? 處理區에서는 時間이 경과함에 따라 增加하는 경향이었으나 ?? 處理區는 급격히 減少했다. 따라서 ??가 ??보다 果汁의 甘味比를 증가시키는 것으로 생각되었다. 아미노산分劃의 比放射能은 ?? 處理區보다 ?? 處理區에서 더 많이 增加했다. The effects of spraying ?? solutions on sugar, organic acid and amino acid levels in citrus(C. unshiu Marc.) fruit juice were examined using the ?? method. Each ?? compound under investigation was measured during the three weeks after ??assimilation. The total carbon compound, which was measured as the specific activity (cpm/㎖) of ??, was transported more into the fruit juice within one week after ??assimilation with the SO treatment than with the ?? treatment. The ?? activity changes of the sugar fraction were very similar in both ?? and ?? treatments although the organic acid fraction was reduced more by ??. The specific activity ratio of the sugar fraction to organic acid was increased rapidly when treated with ??. This indicates that ?? plays a role in raising the ratio of sugar to organic acid. It was found that the ?? activity in the amino acid fraction was higher when ?? was applied.

Dorsal root ganglion(DRG) block by the local anesthetics and steroids which has done classically in low back pain(LBP) patients with radiculopathy has high incidence of recurrence rate and side effects of steroids. Recently a new technique of pulsed radiofrequency thermocoagulation(P-RFTC) was introduced and substituted for it because of the benefits such as relatively low recurrence rate, low risk of nerve injury and comfort during the procedure. We experienced 15 patients who had LBP with radiculopathy and no or little response to epidural steroid injection. When we performed DR ganglionotomy by P- RFTC under the C-arm guide in these patients, we tried to approach the exact DR ganglion using tow cannulas - the one for obtaining patient's subjective symptoms and injection of contrast dye, the other for making a RF lesioning after identifying the impedance of sensory and motor stimulation. In conclusion, DR ganglionotomy by P- RFTC using two cannulas in LBP patients is an easy and safe procedure with satisfactory results.

Background: The OR(operating room) should provide an optimum environment that is safe for the patient and the working personnel. The air ventilation system of OR has been studied to decrease the contamination of air. We investigated the flow and contamination of the air in OR at our hospital. Method: Cultures in OR were made and the number of bacteria and fungi were calculated. A two-dimensional model for the cross-section of an operation room is developed for the CFD (computational fluid dynamics) analysis. The characteristics of air flow in the empty operation room and in the occupied operation room are calculated by using a CFD program. Results: The current air ventilation system of our hospital does not deliver the clean air to the operating site efficiently in occupied OR. Conclusions: We suggested a new location of air ventilation system which improves air venting with little increase of the cost of equipment.
