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.

Although designing and building multiprocessor systems has proceeded at a dramatic pace, the development of effective ways to program them has generally not. And the immense complexity of parallel computation can only increase our dependence on software. So the future of parallel computing depends on the creation of simple but effective parallel programming models. As an attempt to develop those models, the writer developed another version of SubMiranda compiler which was enhanced with the ability of source level mapping of tasks to processors. The result of experiments show the advantages of the introduced technique.

This paper proposes a global motion estimation technique that utilizes the special relations of motion vectors of geometrically symmetrical triple points of frames. The proposed technique calculates several kinds of the parameters, such as panning, tilting, rolling, and zooming of camera motions at once by applying the proposed equation sets to the motion vectors only once, and avoids the trial and error method which the existent works have used. Moreover it discriminates against the foreground region and effectively reflects only the background region into the calculation of motion parameters, thus making the calculation more accurate and fast enough to accommodate MPEG-4 requirements. Experimental results on various types of sequences show the validity and the broad applicability of the proposed technique.

The detection and analysis of chatter behaviour in endmilling is very complex and difficult, so it is necessary to detect and diagnose this chatter phenomenon clearly. This paper presents a new method for detecting the abnormal chatter in endmilling operation, based on the wavelet transform. Using AR spectrum the data that has chatter phenomenon was verified and the fundamental property of chatter and its characteristics in endmilling by using the wavelet transform is reviewed. This result obtained by wavelet transform proves the possibility and reliability of detecting the chatter in endmilling operation.

In this study, new moment-resisting precast concrete beam-column joint is proposed for moderate seismic regions. It has the connection reinforcing bars, penetrated the joint and lap-spliced with the bottom bars of precast U-beam. An experimental study was carried out to investigate the joint behavior subjected to reverse cyclic loading and constant axial compressive load. Three precast beam-column interior were tested. The variables examined were the type of connection reinforcing bars and presence of transverse reinforcement in joint. Joint performance is evaluated on the basis of connection .strength, stiffness, energy dissipation, and drift capacity. Based on the test results, the precast connection is capable of matching or exceeding the performance of the monolithic connection and thereby provides the sufficient moment-resisting behavior to be applicable for moderate seismic regions.

In these years sports marketing has devloped very much and become the most important part in marketing fields. Although sponsorship, above all, is the core of sports marketing, there is little research in this field, So I took up the study of sponsorship from a legal point of view. After stating the purpose and the scope of this study in the first chapter, this thesis outlines the sponsorship dealing with the history, stucture and various types of sponsorship in the second chapter. In the third chapter legal study begins. The third chapter regards sponsorship as a contract between sponsor and sponsored athlete and state how this contract can be made and cancelled. And this chapter also touches on the prearranged amount of damages when one party abides by the contract. In the forth chapter the legal matters relating to the sponsorship are presented. This chapter divides the matters into two, the matters relating to the individual sponsorship contrac( the contract between one athlete and sponsor ) and the group sponsorship contract. The group sponsorship contract is also divided into two.; one is the contract between team and sponsor and the other is the contract that the sponsor promises to sponsor some sport events. According to the system of this classification, this chapter presents many concrete legal matters and problems and then shows the solution of these matters and problems. Finally, in the sixth chapter I briefly summarize the thesis and conclude the study indicating some weak points of the current sponsorship contract.

저자는 정신분열증 환자, 주요우울장애 환자, 양극성장애 환자들의 치료에 사용되는 haloperidol, amitriptyline 및 lithium이 이런 환자들에서 HLA type에 어떠한 영향을 미치는 지를 알아보고자 본연구를 시험하였다. 향정신성 약물을 사용한 경험이 없는 환자 4명을 대상으로하여, 약물을 투여하기 전에 말초 혈액을 채혈하여 HLA 항원형을 결정하였고, 상기의 약물을 2개월 이상 치료용량으로 사용한 후 다시 HLA 항원형을 조사하여 다음과 같은 결과를 얻었다. haloperidol에서는 약물투여전과 약물투여후의 HLA항원형의 변화가 없었다. lithium에서는 HLA B60, HLA Cwl 항원이 소실되었다. amitriptyline에서는 HLA B55 항원이 소실되었고, HLA B75 항원이 발현되었다. 이상의 결과는 인체에서도 amitriptyline 및 lithium이 치료적 용량으로 충분히 사용한 이후 HLA 항원형에 변화를 가져올 수 있다는 것을 알수 있었다. To examine the effects of haloperidol, amitnptyline and lithium on HLA type in vivo, the author conducted microlymphocytotoxicity test on lymphocytes drawn from 4 psychiatric disordered patients, including 2 schizophrenic patients, 1 bipolar disordered patient and 1 major depressive disordered patient before administration of haloperidol, lithium and amitriptyline. After 2 months later, drug therapy was done sufficiently, we reexamine the HLA type on lymphocytes drawn from same patients. The results were as follows : 1) There is no significant changes on HLA type before and after 2 months long halopendol therapy in 2 schizophrenic patients. 2) It was shown that the disappearance of HLA B60 and HLA Cw1 antigen after 2 months long lithium therapy in l bipolar I disordered patient. 3) It was shown that the revelation of HLA B75 antigen and the disappearance of HLA B55 antigen after 2 months long amitriptyline therapy in 1 ma]or depressive disordered patient From the results of present study, we may draw a conclusion that the lithium and amitriptyline therapy cause a revelation of new HLA type and loss of some existed HLA antigens so that these drugs have an effect on HLA typing in vivo experiment.

文性憲 대구보건대학 1994 대구보건대학 論文集 Vol.14 No.-

본 연구에서는 hit and near miss 기법과 error back-propagation network의 비교에서 직관적으로 인지되는 유사성을 소개한다. 그리고 arch 인식용 neural network을 간략히 구성하고 학습시킨후, network link의 weight vector를 hit and near miss 기법에서의 must, must not, may have list로 변환하고 이 list를 다시 network의 weight vector로 변환하는 실험을 통하여 두 방법간의 유사성과 차이점을 관찰한다. In this study, the writer introduces the instinctly conceivable similarities between hit and near miss method and error back propagation network. The writer constructs a simple network to clarify arches and converts weight vectors of network to may-have list, must-have list and must-not-have list. And also, the writer converts these lists to weight vectors. By these procedures, the writer establishes the similarities and differences between these two methods.

In this study, new moment-resisting precast concrete beam-column joint is proposed for moderate seismic regions. it is attempt to devise connection detail which makes workability improve and confirm effective stress transfer in the region of connection. It has the connection details which help working process simplified and construction cost reduced. as replace 9.3㎜, 7strand for reinforcement. Fore specimens for partial tension test and three specimens for beam-column interior joint test were producted. An experimental study was carried out to investigate the joint behavior subjected to reverse cyclic loading and constant axial compressive load. The test variables was transverse reinforcement in joint. Structural performance of joint is evaluated on the basis of connection strength, stiffness, energy dissipation, and drift capacity. Based on the test results, the precast connection is capable of matching or exceeding the performance of the monolithic connection and thereby provides the sufficient moment-resisting behavior to be applicable for moderate seismic regions.
