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.

Recently, the robustness against daily impact is important according to portablization and downsizing of mobile electronics. Especially, almost parts of cellular phone should undergo drop test when they fall 1.5 m above ground. This test simulates the case when cellular phone slips through user's fingers while he is talking on the phone. This paper studies a drop test of auto focusing (AF) actuator for camera module in cellular phone. This component is composed of voice coil motor (VCM) as an actuator and leaf spring as a guide and suspension. The leaf spring's deformation is essential for the test because its permanent distortion disables the focusing, and then, a high quality photograph cannot be obtained. Up to now the drop test has been carried out after fabricating real AF actuator. We propose a dropt test model which simulates the drop test based on finite element analysis. This model makes us enable investigate the stress acting on the clamping and curved parts of leaf spring. Stress over Von Mises criterion lets the spring deformed permanently, and then AF actuator malfunctioned, It helps us to design and modify AF actuator without manufacturing the real product. And also, it saves the time and cost for the development of new products.

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.

Objectives The aims of this study are to estimate the prevalence of the DSM-IV psychiatric disorders in the Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI), and to compare those with previous studies. Methods The Korean Epidemiologic Catchment Area study Replication (KECA-R) was Conducted between August 2006 and April 2007. The sampling of the subjects was carried out across 12 catchment areas. A multistage, cluster sampling design was adopted. The target Population included all eligible residents aged 181o 64 years. Face-to-face interviews were conducted with the Korean version of Composite International Diagnostic Interview (K-CIDI) based on the DSM-IV (N=6,510, response rate=81.7%). Results A total of 6,510 participants completed the interview. The lifetime and 12-month prevalence rates for all types of DSM-IV disorders were 30.0% and 17.3%, respectively. Those of Specific disorders were as follows : 1) alcohol use disorder, 16.2% and 5.6% ; 2) nicotine use disorder, 9.0% and 6.0% ; 3) specific phobia, 3.8% and 3.4% ; 4) major depressive disorder, 5.6% and 2.5% ; and 5) generalized anxiety disorder, 1.6% and 0.8%. Data relating to nicotine and alcohol use disorder revealed a very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among females than males. Conclusion The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in the distribution of psychiatric disorders across the country and times were observed.

인터넷이 인류사에 등장한 것은 지금으로부터 30년에 불과 하다. 인터넷은 개방성과 공개성 그리고 수평성을 지향한다. 이러한 특성을 기반으로 해서 인터넷은 디지털 경제를 구체화시키고 실현시키는 중요한 수단이 되고 있다. 현재 주목받고 있는 P2P(Peer-to-Peer)는 인터넷의 이러한 이상을 실현해 가는데 중요한 위치를 차지하고 있다. 개인과 개인간의 정보공유 모델인 P2P는 인터넷을 통해서 다른 사용자들과 정보를 주고받을 수 있는 기술을 말한다. 또한 컴퓨터 네트워크를 통해서 교환되는 정보의 양의 증가와 함께 네트워크의 보안성이 새로운 문제점으로 부각되고 있다. 네트웍에 있는 어떤 사용자가 제한하기 위해서공개된 환경에 있다고 가정하면, 각 사용자간에 허가받은 사용자에게만 접속을 는 서비스에 대한 요구를 인증 해야한다. 본 논문에서는 이를 해결하기 위해 P2P 환경에서 보안을 유지하는 방법을 제안하고, P2P 환경에서 안전하게 정보를 공유할 수 있는 메커니즘으로 Kerberos 인증 메커니즘을 인용하여 인증 메커니즘을 설계하였다. It is not more in 30 years from now that internet appears to history of man.Internet intends patency and patency and horizontal. According as progress by information society, computer network use and enlargement of scale are accelerated more. Also, with good physician increase of information that is exchanged through computer network, security of network is embossed to controversial point that is new. Because P2P as that remove or weakens center server function is open network that can participate between each user, problem about authentication between each users is risen. If certain user in network is in open environment, this user must authenticate request about service to user who is admitted between each user to limit connection. This treatise proposed method to keep security in P2P environment to solve this and designed certification mechanism that quote Kerberos certification mechanism to mechanism that can share information safety in P2P environment.

Automatic mesh generation for three-dimensional structures
이준성 경기대학교 2000 論文集 Vol.44 No.2
This paper describes an automatic finite element (FE) mesh generation for three-dimensional structures consisting of free-form surfaces. This mesh generation process consists of three subprocesses: (a) definition of geometric model, i.e. analysis model, (b) generation of nodes, and (c) generation of elements. One of commercial solid modelers is employed for three-dimensional solid and shell structures. Node is generated if its distance from existing node points is similar to the node spacing function at the point. The node spacing function is well controlled by the fuzzy knowledge processing. The Delaunay method is introduced as a basic tool for element generation. Automatic generation of FE meshes for three- dimensional solid and shell structures holds great benefits for analyses. Practical performances of the present system are demonstrated through several mesh generations for three-dimensional complex geometry.
