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.

This study was conducted to examine middle and high school students' knowledge level of first aid, health promotion, and safety. Data were collected from 1.165 students from March 6, 2000 to April 4, 2000. The results of this study are summarized as follows. 1.80.1% of the respondents felt the necessity of first aid. The sources of information about methods of first arid were school (43.9%), mass media (15.6%), and self-study (10.5%). 30.0% of them never leaned the methods of first aid. 2.In the case of obtaining information on first aid through mass media, 58.2% of them got it from TV. 7.3% of them obtained it from magazines, while 5.8% of them got it from newspapers. According to their viewpoints of adequate time to teach the methods of first aid, 38.6% of them thought that the methods had to be taught in the primary school and 25.2% of them thought that they had to be taught in the kindergarten. 24.9% of them replied that the methods had to be taught in the middle school, while 11.3% of them replied that they had to be taught in the high school. 3.The points for knowledge of first aid were 98.29±20.91 on the basis of 150 points (65.5 points on the basis of 100 points). The points showed significant differences in the variables of sex, education level, numbers of siblings, parents' education level, and guardian's occupation.

Objectives : Diffusion tensor imaging (DTl) studies of schizophrenia, thus far, have mainly focused on white matter abnormalities reflected in anisotropy indices such as fractional anisotropy (FA), but recently, new implications of apparent diffusion coefficient (ADC) have been proposed. This is. to our knowledge, the first study to analyze ADC maps of schizophrenic Patients using statistical parametric anatomical mapping (SPAM). Methods : DTl was performed in 20 schizophrenic patients and an equal number of age- and sex-matched healthy controls. ADC maps were then generated, from which 98 volumes of interest were extracted using SPAM. Probability-weighted mean values of ADC were calculated from each volume of interest and compared between the two groups. Results : Significantly higher mean ADC values were observed in patients with schizophrenia compared to healthy controls in the following volumes of interest: bilateral hippocampal formation, bilateral uncus, nght thalamus, light temporal lobe white matter, right superior temporal gyrus, bilateral insula and right lateral ventricle. Conclusion : The results support the recently proposed assertion that regionally increased ADC may reflect cortical brain atrophy. In addition, a new possibility is raised that a neuropathological event involving both the gray and the white matter may also play a role.

버팀보로 지지된 흙막이벽의 거동에 관한 연구

홍원표,여규권,윤중만,조용상 중앙대학교 기술과학연구소 1997 기술과학연구소 논문집 Vol.27 No.-

버팀보 축력으로부터 산정된 측방토압은 지표면에서 굴착깊이의 17%에 해당되는 깊이까지 선형적으로 증가하다가 그 깊이 아래로부터는 일정토압분포를 보이는 사다리꼴모양의 분포를 보였다. 이 일정토압 분포부분의 토압 크기는 평균적으로 최종굴착깊이에서의 Rankine 주동토압의 58%에 해당하거나 연직상재압의 17%에 해당하였다. 또한 흙막이벽의 수평변위와 굴착깊이와의 관계로부터 흙막이구조물의 안정성을 판단할 수 있는 시공관리기준을 설정하였다. 흙막이벽의 수평변위량이 굴착깊이의 0.20%보다 작으면 흙막이벽과 굴착배면지반은 안정된 상태에 있다. 그러나 벽체의 수평변위가 굴착깊이의 0.20%보다 크게 발생하면 굴착공사의 안정성을 주의깊게 관찰해야만 하며, 필요하다면 흙막이 구조물을 보강해야만 한다. The lateral earth pressures on braced earth retaining walls, which are estimated form the measured strut force, shows a trapezoidal distribution that the earth pressure increases linearly with depth from the ground surface to 17% of the final excavation depth, and then keeps constant value. The maximum lateral earth pressure was same to 58% of Rankine's active earth pressure or 17% of the vertical overburden pressure at the final excavation depth. Also, empirical criterion is established for construction management to monitor and ensure the stability of deep excavation from the relationship between horizontal displacement of wall and excavated depth. If the horizontal displacement of wall measured from inclinometer shows less than 0.20 percent of the excavated depth, the retention wall and surrounding ground exist under stable state. When the horizontal displacement is developed more than 0.20 percent of the excavated depth, excavation works should be carefully observed and reinforced the earth retention wall, if necessary.

취업대비 기사자격증 취득을 위한 효과적 학습지도 방안에 관한 연구

홍순욱,윤상원,서용성 永同大學校 1997 硏究論叢 Vol.3 No.1

지난 2년간 STC를 수행하면서 경험한 바에 의하면, 기사시럼을 준비하기 위하여 시중에서 구입한 연습 문제집에 실린 일부 문제들이 내포한 모호성 때문에 많은 학생들이 어려움을 겪고 있다는 것을 알게 되었다. 이는 학생들이 전공지식을 학습하는데 있어서 비효율을 초래하는 주요 요인들 가운데 하나일 것이다. 본 논문은 학생들이 스스로 자신들의 지식을 확장하고 조직화할 수 있도록 「기출문제 수정출제법(PRST)」이라는 새로운 개념을 도입함으로써 그와 같은 부정적인 효과를 최소화하려는 구체적인 노력을 보여주고 있다. PRST는 5단계로 구성되어 있는데, 이를 통하여 학생들과 지도교수는 모호성을 제거하고 문제를 개선하는 작업을 함께 하게 된다. 이를 위하여 시스템적 접근의 관점에서 Dick의 모형을 채택하는데, 이 모형은 교수설계를 위한 기본틀을 제공해 주며, 본 연구에서 다룰 하나의 기능은 그러한 교수설계 모형 가운데 일부가 된다. 교수설계 모형에 있어서 8개의 기능 가운데, 일련의 개선된 연습 문제들을 제작하는 것이 학생들에게 우선적으로 도움이 될 것이라는 관점에서 수업교재의 개발이라는 기능이 가장 긴급하다고 판단되었다. 본 연구의 목적에 부합하는 적절한 연구의 방향과 범위를 결정하기 위하여 기존 문제들에 대한 사전 조사연구가 수행되었다. 그리고 두 과목에 대한 연습 문제집의 제작과 학생들의 학습 동기부여를 위하여 여름방학 STC기간에 PRST가 시험적으로 적용되었다. 제작된 연습 문제집 가운데 하나가 문제집의 양호도라는 측면에서 6개의 7점 Likert척도로 학생들에 의하여 인지적으로 평가되었다. 그 결과, 새로 구성된 연습 문제집이 기존의 연습 문제집보다 여러 각도에서 더 양호하다고 판정된다. 이것은 통계적 적용상의 한계에도 불구하고, 본 연구에서 제안된 PRST 뿐만 아니라 제작된 연습문제집의 질적 부분의 타당성은 최소한 뒷받침된다는 것을 의미한다고 하겠다. By what we have experienced in STC for the last two years, we can see that a number of students have been suffering from the ambiguities of some problems contained in exercise books which are available at the market for preparing the National Certificate of Engineering. This seems one of the primary factors that bring on inefficiencies in learning expertise. This paper reports our concrete efforts to minimize such a negative force by introducing a new concept of「process for Revise of Sample Test(PRST)」, so that students can be able to organize and expand their knowledge in a good manner. PRST consists of five stages that enable students and the instructor work together on improving problems by getting rid of ambiguities. From the viewpoint of systems approach, Dick's model is adopted to provide a framework for an instructional design which designates a function we deal with in this study. Among the eight functions in the model, the development of class material is considered to be most urgent in that it would be of highly benefit to students to make series of improved exercise problems. Preliminary investigation of existing problems is conducted to figure out right direction and scope for the purpose of our research. PRST is, then, tentatively applied during the summer STC not only to produce exercise books for two different subjects, but to motivate students. One of the produced exercise books is examined perceptively by students in terms of goodness using six seven-point Likert scales. The result shows that the newly constructed exercise book is, on the perception basis, likely to be better than existing books. This implies that the quality of the produced book, as well as the proposed PRST, is validated at least positively in spite of statistical limitation.

We studied on the regularized iterative restoration method considering edge-sensitive parameters in order to make edge sharpening and suppression of the noise amplification in the course of restoration. Proposed method estimated regularization parameter and relaxation parameter from each pixels of the restored image for each iteration and applied them to the next iterative restored image in order to enhance the edge sharpening in the edge region and to reduce the artifacts in the flat region, while the conventional method use the constraints determined experimentally. Through the experimental results we verified that the proposed method showed the better results compared with the conventional regularized iterative restoration method. Proposed method has the better restoration results for the restoration of nosiy-blurred image.
