The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

This paper introduces a development of an electrical stimulator for auditory stimulation. The electrical stimulator is useful in neurotological diagnosis, audiological evaluation, candidate selection for cochlear implantation, optimal device selection and decision making of MAP strategy for severe-to-profound hearing impaired persons. The development was based on sound parameters of auditory brainstem responses and auditory electrophysiological characteristic such as effective firing of auditory nerve and recording evoked potentials during refractory period of neuron. Besides pulse parameter could adjustable by programming for more varied electrical stimulation evoked response audiometry. Using the electrical stimulator, electrical square pulse was applied to promontory, and electrically evoked auditory brainstem response and electrically middle latency response were successfully recorded in cats.

This study was performed to investigate the strength characterstics of steel fiber reinforced recycled aggregate concrete. Test specimens were prepared with compressive, split tensile, flexural specimens and tested by ultimate strength. A superplasticizer and fly-ash were added to the mix to improve performance of recycled concrete. Test-variables are substitution of recycled aggregate(0, 30, 50%), steel fiber length(0, 30, 50, 60mm), steel fiber content(0, 0.5, 1.0, 1.5%). Test-specimen were classified by test-variables. The experimental results on the various engineering properties of steel fiber reinforced recycled aggregate concrete using waste concrete are summarized as follows. It was found that the compressive and split tensile strength were proportionally affected by quantities of recycled aggregate substitutions, but flexural strength wasn't. The maximum compressive strength was 392 kgf/㎠( series 4 : R30 L30 V1.0 A20 ), the maximun split tensile strength was 40 kgf/㎠( series 7 : R30 L30 V1.5 A20) and the maximum flexural strength was 62 kgf/㎠( series 7 : R30 L30 V1.5 A20 ).

The determination of peripheral nerve conduction velocity is and important part to electrodiagnosis. Its value as neurophysiologic investigative procedure has been known for many years but normal value of median and ulnar motor nerve was poorly reported in Korea. To evaluate of median and ulnar motor nerve terminal latency, amplitude of CMAP(compound muscle action potential), conduction velocity and F-wave latency for obtain clinically useful reference value. 71 normal volunteers(age,19-65 years;142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking Ⅱ was use for detected terminal latency, amplitude of CMAP, conduction velocity and F-wave latency of median and ulnar motor nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation, independent t-test was used to compare between Rt and Lt side also compare between different in genders. The results are summarized as follows: 1. Median motor nerve terminal latency was right 3.00ms, left 2.99ms and there was no significantly difference between right and left side and genders. 2. Median motor nerve amplitude of CMAP was right 17.26mV, left 17.50mV and there was no significantly differences between right and left side and genders. 3. Median motor nerve conduction velocity was right 57.89m/sec, left 58.03m/sec and there was no significantly difference between right and left side and genders. 4. Median motor nerve F-wave latency was right 25.74ms, left 25.59ms and there was significantly differences between genders. 5. Ulnar motor nerve terminal latency was right 2.38ms, left 2.45ms and there was significantly differences between right and left side. 6. Ulnar motor nerve amplitude of CMAP was right 15.99mV, left 16.02mV and there was no significantly differences between right and left side and genders. 7. Ulnar motor nerve conduction velocity was right 60.35m/sec, left 59.73/sec and there was no significantly differences between right and left side and genders. 8. Ulnar motor nerve F-wave latency was right 25.53ms, left 25.57ms and there was significantly differences between genders.

Purpose: PFME(Pelvic floor muscle exercise) has been used in stress Incontinence patients as a primary treatment. The purpose of this study is to evaluate the efficacy of well structed PFME with functional electrical stimulation in these patients. Materials and methods: Ninety five women with stress incontinence were assigned to pelvic floor muscle training program. The mean age of the patients was 43.5 years and according to the Stamey grades, 50(52.6%) were grade 1, 42(44.2%) were grade II and 3(3.2%) were grade III. In principle, we performed electrical stimulation. of 2 times a day, each 30 minutes in length and continued for at least 3 months. Results: In our study, overall success ratee was 76% at lmonth, 96.3% at 2months, 94.4% at 3months and 92% at 6months after treatment, at respectively. The cure rate according to the symptom grade was 48% in grade I, 23.8% in grade II and 0% in grade III, so the degree of grade was significant parameter predictive of a good outcome (p<0.05). Intravaginal pressure increased by 10cmH2O. Increased vaginal pressure was found in 93% of the patients and at least 50% improvement was 61%. Conclusion: PFME using functional electrical stimulation is more effective for the patients who have good compliance, low degree stress incontinence. In order to attain and maintain good results, a well structed program that teaches specific muscle exercise should be used and the patients should be followed by a maintenance program and reinforcement.

Cefradine, first generation cephalosporins, is a water soluble antibiotic agent. We prepared the alginate beads containing cefradine for developing release and evaluated the dissolutions of cefradine from beads. Cefradine was encapsulated into inner water phase of W/O/W emulsion beads which were prepared by cross-linking of alginate with Ca^2+. The delayed release patterns of cefradine for W/O/W emulsion beads were observed as it was compared with alginate simple beads without oil phase. As a results, W/O/W multiple emulsion beads could be use a controlled release DDS of water soluble agents such as cefradine. Also chitosan of high M.W could be a good intermediator of controlled release DDS.

Nowadays there are going to be performed various researches about the operation and management of container terminals. By these researches, problems that arise in operation of container terminals are examined and solved. However the analysis of a port loading equipments actually wastes many time and much money. In these cases, the simulator is the most efficient means among related researches. Therefore this paper studied on a simulator for intelligent port handing equipments. The simulator divided loading courses into five steps and each step made in a module. The virtual port has many 3D objects and objects move each other independently. In this environment, the more 3D objects have, the more the simulator slows by dropping FPS. This problem is solved by the maintenance technique of many objects. Because It took many objects of a container box and guaranteed better FPS.

Wilms' tumor is the paradigm for multimodal treatment of a pediatric malignant solid tumor. Developments in surgical techniques and postoperative care, recognition of the sensitivity of Wilms' tumor to irradiation, and the availability of several active chemotherapeutic agents led to a dramatic change in the prognosis for most patients with this once uniformly lethal malignancy. This article presents four cases of Wilms' tumor managed at Chungnam National University Hospital and reviews current treatment recommendations for patients with Wilms' tumor, based upon the results of the National Wilms' Tumor Studies.
