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 paper is the eye region which is used with confirmation element of face image it uses the SIFT and it extracting method proposes. The eye region image where becomes model and it composes the keypoint descriptor which is a SIFT result of the input image which it will extract. It uses the keypoint descriptor which and creates it composes a each feature vector, and the judgement where affine transform should have existed on after two feature points which adjusts with each other, against the feature point field which confront above half as the case eye region where the with each other same affine transform will exist it judged. There is not a test result learning process, more quickly recognition method of existing methods than the possibility of getting the result which extracts the region it was.

황의성,정재진,김태형,김두영 동아대학교 정보기술연구소 2006 情報技術硏究所論文誌 Vol.14 No.1

MPEG-4 for an object base coding after extracting the region from image, the coding for a real-time requirements is quick and must be accurate. The object crisis algorithms of existing calculation quantity are many and with image transformation or video conferencing system to same real-time application they are not suitably. The object real-time tracking it tried to apply the CAM-Shift algorithm which is possible from the dissertation which it sees consequently. Tracking the object which it moves or wants the VO where (Video Object) tracking the user wants in bounding box form defines the object where is started. Tracking the object of after uses a CAM-Shift algorithm and are extracted and the VOP with the VO which it is composed. It defines one bounding box with the method which is proposed consequently about lower only one VOP there to be it will be able to compose, it becomes.

The (0.8BaTiO₃-0.1SrTiO₃-0.1MgTiO₃)+0.006Nb₂O5 ceramics were fabricated by conventional ceramic process. The dielectric property of specimen was investigated that the specimen was sintering temperature at 1,300℃ for 3hours and them annealed at 1,100℃ for 3hours in a atmosphere (air) to be painted on the surface with CuO paste. The results of the temperature and frequency are varied, the dielectric constant and loss tangent are unsuitable for BL capacitor. The dielectric constants were varied to be negative temperature coefficient(2,000∼3,000) in the temperature range between -10 and 140℃, the dissipation factors (tan δ) were some high(0.1∼0.3). It was not grain insulation, in cause of the some difficult to be annealed temperature with CuO paste and fired atmosphere. But, we have some different annealing temperature and fired atmosphere. it will be suitable BL(Boundary Layer)capacitor.

The purpose of this study was to determine the relationship of demographic characteristics to job stress among security guards. The subjects in this study were 474 people selected by random cluster sampling from a population that consisted of private bodyguards and security guards from Seoul, Gyeonggi province and Daejeon. They gave a faithful response when a survey was conducted, and incomplete answer sheets from the others of the population were excluded. For data analysis, SPSS/PC Windows V11.0 program was utilized, and frequency analysis, t-test, one-way ANOVA and Scheffe posttest were employed. The findings of this study were as follows: First, the gender of the security guards investigated made a significant difference to their job satisfaction(p<.05). Job characteristics, compensation and organizational characteristics put higher strain on the men than on the women, and the latter group was more stressed out about their roles and interpersonal relations. Second, their age, education, years of services and monthly income made a significant difference to their job stress subvariables related to job characteristics, roles, human relations, compensation and organizational characteristics(p<01). Third, their job stress was significantly different according to their position and status(p<01). Specifically, those who had no position were under heavier pressure due to job characteristics, roles, interpersonal relations, compensation and organizational characteristics.

In treatment of trochanteric fractures of the femur, reduction in stable position and rigid internal fixation is required to decresse mortality and morbidity by early ambulation and early weight bearing, especially in elderly. In treatment of unstable fracture, early ambulation and early weight bearing is possible by medial displacement and internal fixation in valgus position with satisfactory result. From Jan. 1973 to Mar. 1978, 50 trcchanteric fractures were treated by surgical measure. at orthopaedic surgery department, Chungnam Naticnal University Hospital, and following results were obtained. 1. Of 50 cases of trochanteric fractures, 36 cases were male, 14 cases were female. 2. In male the incidence was relatively even over all age groups, but in female most of them occured in elderly patient over 60 years old. 3. The most common cause of fracture was traffic accident in all and in male, but in. female slip down was. 4. Unstable type was 62% and comminuted type was most common. 5. In unstable type, stable reduction and rigid fixation was achieved by medial displacement and internal fixation in valgus position with satisfactory result. 6. The incidence of early complication was markedly reduced by early ambulation. 7. The most common late complication was coxa ware deformity and it was mainly noticed in unstable fracture reduced in anatomical position.

Y₁Ba₂Cu₄O 고온 초전도체의 임계전류 밀도에 관한 연구

김의훈,김재욱,김채옥 漢陽大學校 基礎科學硏究所 1992 基礎科學論文集 Vol.11 No.-

Y₁Ba₂Cu₄O? 고온 초전도체의 전이온도 Tc?은 자화측정으로부터 84K이었고, 5K와 77K에서의 임계전류 밀도 (Jc)는 Bean의 임계 상태 모델을 이용하여 구했다. 그 값들은 10³~10⁴A/㎠ 범위에 있었으며, Y₁Ba₂Cu₄O?의 임계전류 밀도는 Y₁Ba₂Cu₃O??의 것과 비교해 볼 때 낮았지만, 자기장에는 덜 민감하였다. 또한 임계전류 밀도가 고온에서는 자기장에 매우 민감하나 저온에서는 자기장에 따른 변화가 작음을 관찰하였다. From magnetization measurements, the critical temperature Tc? of high Tc superconductor Y₁Ba₂Cu₄O? was 84K and the critical current densities, Jc, at 5 and 77K were determined using the Bean critical state model. Magnetic critical current densities were in the range 10³~10⁴A/㎠. As compared with the results from Y₁Ba₂Cu₃O??, the Jc values from Y₁Ba₂Cu₄O? were observed to be lower and less sensitive to the magnetic field. At low temperature(5K), the critical current density showed a weak field dependence while the rapid fall in Jc was observed at higher temperatures.
