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 and Objectives : Many students major in applied music singing have various difficulties in phonation when they sing or perform. But the studies about this cause are lack. The purpose of this study is whether singing voice therapy based on vocal music is effective or not to applied music singing students that have difficulties in phonation. Materials and Methods : Singing voice therapy program had been done to 8 students major in applied music singing during 7 weeks. We did laryngeal stroboscope, perceptual, acoustic and aerodynamic examination before and after singing voice therapy to this students. And we studied post examination results have differences or improvements compared to pre examination results. Results : Four male students don't have effective improvement after singing voice therapy but they shows slight improvement in aerodynamic examination values compared to pre examination values. Four female students shows improvement in aerodynamic examination values and pitch range increasing. Above all, one student's vocal nodules disappeared after singing voice therapy. Conclusion : Singing voice therapy based on music singing is very effective to the students major in applied music singing. Above all, their curriculum in applied music singing should include phonation training based on music singing before training perform and technic practices.

We investigate the performance of robust pattern matching for defocused images used to recognize an object. The matching method uses the nonlinear joint transform correlator(NJTC) which is able to change the relative contribution of the phase and amplitude signals. Here the nonlinearty is used to make the robustness of the camera focusing. Computer simulation is used to show the correlation peak intensity, peak intensity, peak-to sidelobe ratio for defocused images.

Objectives: For the last two decades. various chemicals have been applied for the treatment of spinal cord injury but no chemicals were found to be as effective as methylprednisolone. And motor evoked potentials(MEPs) have been utilized clinically in monitoring and diagnosis of the motor disorders. To evaluate the efficacy of methylprednisolone on functional recovery following spinal cord injury and to determine the usefulness of motor evoked potential as a monitoring tool in spinal cord injury, the author used spinal cord injury model in rats. Methods: In the present study, the effects of methylprednisolone on functional recovery after spinal cord injury were carefully quantified behaviorally as well as electrophysiologically in white rats. Spinal cord injury was produced using NYU-spinal cord impactor. BBB(Basso, Beattie, and Bresnahan) test was conducted to measure the change of neurological status behaviorally, and MEPs and somatosensory evoked potentials (SSEPs) were recorded to determine the effects of methylprednisolone electrophysiologically. The results of these studios were compared each other to determine the usefulness of MEPs. Results: 1. According to the behavioral test using BBB test, methylprednisolone - treated animals showed improved functional recovery compared to the saline-treated animals. 2. MEP latencies in methylprednisolone-treated group were shorter than those in control group. Peak amplitudes of MEPs were larger in methylprednisolone-treated group than those in control group. 3. Peak amplitudes of SSEPs were larger in methylprednisolone-treated group than those in control group. In summary, the amplitudes of MEPs were recovered more rapidly in methylprednisolone-treated group than those of SSEPs and the latencies of MEPs showed similar tendency compared to those of SSEPs. 4. The thresholds of MEPs and SSEPs tended to be lower in methylprednisolone-treated group than those of control group. Conclusions: These results suggest that methylprednisolone may minimize the secondary spinal injury and improve the functional recovery after spinal cord injury. And motor evoked potential seems to be reliable as a tool monitoring the functional recovery after spinal cord injury, and be compensatory with SSEPs.

We have investigated the effects of electrical stress on poly-Si TFTs with different hydrogen passivation conditions. The amounts of threshold voltage shift of hydrogen passivated poly-Si TFTs are much larger than those of as-fabricated devices both under the gate bias stressing and under the gate and drain bias stressing. Also, we have quantitatively analyzed the degradation phenomena using by analytical method we have suggested that the electron trapping in the gate dielectric is the dominant degradation mechanism in only gate bias stressed poly-Si TFT while the creation of defects in the channel region and poly-Si/SiO_2 interface is prevalent in gate and drain bias stressed device.

본 논문에서는 적합성 시험에서 EFSM(Extend Finite State Machine) 모델에 대한 데이타부분 시험열을 효율적으로 생성시켜 주는 탐색 방법에 대해 제안하였다. 이 탐색 방법에서는 depth-first search와 같은 기존의 탐색 방법과는 달리 탐색 초기에 다양한 경로가 찾아진다. 이미 제안된 시험열 생성 방법인 데이타 값을 바탕으로 하여 시험열을 생성하는 방법에서 이 탐색 방법을 이용하였을 경우 기존의 탐색방법을 이용하는 것보다 효율적으로 시험열을 생성할 수 있다. 본 논문에서는 Inres 프로토콜에 이 탐색 방법과 기존의 탐색 방법인 depth-first search를 각각 적용하여 시험열을 생성, 비교하여 보았으며, 제안된 탐색 방법을 이용하면 같은 시험 범주를 가지면서도 짧은 길이를 갖는 시험열을 효율적으로 생성할 수 있음을 알 수 있다. In this paper we proposed a searching algorithm for generating test cases, which can test data part of EFSM model in conformance test. In a different way to existing algorithm like depth-first search algorithm, this one can find various paths in the early stage of searching. When it is used in readily proposed test case generation method which is based on the value of variables and parameters it can generate test cases efficiently than in the case of depth-first search algorithm being used. We generated test cases for Inres protocol using each of proposed and depth-first search algorithm, and compared these two methods. proposed algorithm can generate much shorter test sequences efficiently than existing one.

Pancreatic cystadenoma is very rare, slow growing tumor and generally preoperative differential diagnosis may be difficult. A 43-year-old female was admitted to our hospital with the complaint of abdominal discomfort in the epigastrium for about preceeding 5 years. Ultrasonography and Computed tomography were performed. When endoscopic retrograde cholangio-pancreatogram was performed, displacement of distal pancreatic duct by huge mass was noted and injected dye was drained irregulary into the cavity of mass. Distal pancreatectomy was performed with splenectomy. The mass size of distal pancreas was 7X4cm, and the cyst contained with yellowish thick mucoid fluid. Diagnosis was confirmed the mutinous cystadenoma of the pancreas on histologic examination.

This study was conducted to investigate the effect of nitrogen and potassium fertilizers applied to forage crops grown alone and in mixture with grass and legumes of forage crops, on the yield of dry matter. The results are summarized as follows; 1. Nitrogen fertilizers for the yield of dry matter showed highly effective to orchardgrass in case of grown alone and were also effect of grown in mixture alfalfa and grasses, but potassium fertilizers did not show any significance on the dry matter yield increases compared with control. 2. In nitrogen fertilizer plots. alone and mixed sowings showed the total yields of dry matter in decreasing order of tallfescue>orchardgrass>alfalfa and alfalfa+orchardgrass (5:5)>alfalfa+orchardgrass(3:7)>alfalfa+orchardgrass(7:3)>alfalfa+tallfescue(3:7)>alfalfa+tallfescue (7:3)>alfalfa+tallfescue (5:5), respectively. 3. With nitrogen fertilizers for the yield of dry matter was highest effective with the application level of 20㎏/10a throughout the plots. except the with nitrogen plot of grown alone of alfalfa and orchardgrass. 4. In case of grown in mixture with grass and legume increasing total yields of dry matter with nitrogen and potassium fertilizers was ascribed to increase grasses. but botanical composition of alfalfa was decreased.
