In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(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 menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. 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 64.5% in 1998.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

The effects of several tonifying prescriptions on the apoptosis of transplanted L1210 cells and the regulation of immune cells in L1210-transplanted mice were studied. Sa-Mul-Tang(SMT), Sa-Kunja-Tang(SKT), Sipjeon-Daebo-Tang(SDT) accelerated the apoptosis of transplanted L1210 cells, and SMT and SKT reduced the mitochondrial transmembrane potential of transplanted L1210 cells. SMT promoted the proliferation of thymocytes and splenocytes in L1210-transplanted mice. Whereas SMT increased CD8+ T_c/T_S cell, Bojung-Ikki-Tang(BIT) decreased CD4+ T_H cell population in the thymocytes of L1210-transplanted mice. SMT and SKT increased the lucigenin chemiluminescence from peritoneal macrophage of L1210-transplanted mice. These results indicate that SMT and SKT have an inductive action of apoptosis of transplanted L1210 cells and peritoneal macrophage activation.

The purpose of this study was to compare the bond strength of single bottle type dentin bonding systems to conventional dentin bonding systems and to evaluate the relationship of the hybrid layer to the shear band strength of single bottle type dentin bonding systems. The results were as follows; 1. Mean shear bond strengths of single bottle type dentin bonding systems ranged from 12,48±2.63 MPa for One-Step to 16.71±4.59 MPa for Optibond Solo, comparing 19.14±4.84 MPa for Scotchbond Multi-Purpose Plus of conventional adhesive system. 2. Single bottle type dentin bonding systems produced hybrid layers similar in morphology to the convention adhesive system. 3. The thickness of the hybrid layers were 2∼3 ㎛ for EG Bond, One-step, and Prime&Bond 2.1, 3∼5 ㎛ for Optibond Solo and Single Bond. 4. The thickness of the hybrid layer of Scotchbond Multi-Purpose Plus which is one of conventional adhesive was 6∼8 ㎛. 5. In the fractured surface, resin tags, resin cohesive fracture and dentin cohesive fracture were observed. 6. The relationship of the hybrid layer and the shear bond strength was confirmed.

특수학급의 이러닝 활용 실태와 요구 조사

우정한,김영걸,신재훈 국립특수교육원 2006 특수교육연구 Vol.13 No.2

특수교육 분야에서는 이러닝을 통하여 장애학생 교육 서비스의 양적·질적 발전을 위한 다각적인 노력을 모색하고 있다. 그러나 특수교육 현장의 실제 활용 실태와 이와 관련된 구체적인 요구에 대한 기초연구가 부족하여 효과적인 이러닝 실행을 위한 지원 방향을 수립하지 못하고 있다. 따라서 본 연구는 특수학급 교사들을 대상으로 설문조사를 실시하여 특수학급의 이러닝 관련 환경과 활용 실태를 탐색하였고, 특수학급구성원들이 가지고 있는 이러닝 실행과 관련된 요구를 밝혔으며, 이를 바탕으로 특수학급에서 이러닝을 효과적으로 운영하고 실행하기 위한 시사점을 제시하였다. E-learning is learning that utilizes contents crafted based on multimedia and hyper media via diverse information technologies. It enables teaching and learning to allow disabled students to utilize contents crafted with diverse latest techniques, thereby expanding the forum of learning. Thus, the special education area is making diverse efforts to achieve quantitative and qualitative development of educational services for disabled students through e-learning. However, since basic research is lacking with regard to the actual utilization status of e-learning and corresponding needs in special education, an appropriate support direction for performing e-learning cannot be determined. Against such a backdrop, this research surveyed the e-learning status and needs in special classes. Likewise, it surveyed the environment and utilization status of computers, software, and assistive technology that special classes in 'B' and 'D' city owned for e-learning. It also surveyed hardware and software requirements for effectively performing e-learning in special classes.

It is difficult to analyze the behavior of the geogrid reinforced soil walls, because most of the design methods for the reinforced soil structures with geogrids are based on the theory of the rigid-plasticity which takes no account of displacement and deformation of reinforcing material in the soil. In this study, the finite element analyses of geogrid reinforced retaining walls are performed to suggest an useful design method which consider the displacement and deformation of reinforcing material in the soil. The reinforcing effects on geogrid reinforced retaining wall are related with the length and interval of reinforcing materials. So the effects are analyzed with four different interval of reinforcing materials. It can be concluded from the results of analyses that the wall displacement, the earth pressure on the wall, the vertical stress distribution in the foundation and the settlement of backfill surface are decreased in direct proportion to the decrease of the interval.
