Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of 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 means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : 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 45.5% in 1997.

The capacity of direct-sequence code-division multiple-access (DS/CDMA) systems is co-channel severely limited by multiple access interference (MAI) produced by the other users. To improve the capacity, joint-detection receivers and MAI cancellation techniques have been proposed.[1][2][3] This paper presents an adaptive neural network-based receiver that has the capacity of combating the 'near-far' problem and rejecting the multi-user interference in a multipath channel.[4] A comparative performance analysis of the conventional receiver and the adaptive neural network receiver is camel out using a Monte Carlo simulation. It is found that the new receiver performs extremely well in multipath and multiple access channels with a significant 'near-far' effect.

Cystic lesions of the mandible are fairly common and usually a presumptive diagnosis is made readily, more often on the basis of roentgenographic appearance than by any other means. Occasionally, however, it is easy to fall into errors of diagnosis which may affect one's choice of treatment. The diagnosis in these situations are usually resolved by the histopathologic examination of material obtained by surgical exploration. The present discussion to the lesions which can be most easily confused in the roentgenographic interpretation, that is, the traumatic bone cyst, the dentigerous cyst, the radicular cyst. These lesions often grow to considerable size before they cause any subjective or objective symptoms. Less frequently, perhaps, the patient presents himself with the complaint of enlargement of the affected part, a discharge, or pain. On rare occasions the first sign is fracture through the cyst cavity. In any case, an adequate roentgenographic survey by means of extraoral films is essintial. This is the primary means of diagnosis. The three lesions in mandible, reported here, resembled each other roentginographically in that they were osteolytic lesions. THe follicular and radicular cysts usually have a smooth periphery and may be surrounded by a white line. The follicular cyst, slow-growing lesions, is usually associated with an unerupted tooth. The radicular cyst, the most common type of the odontogenic cyst, is always associated with a nonvital tooth, or it may persist as a "residual" radicular cyst after the causative tooth has been extracted. The traumatic bone cyst can often be differentiated from the first two in that the periphery is less definite and is irregular. It is thought that because it does not occur in older people, the lesion is self-limiting and heals spontaneously if left alone.

國家에 의한 一方的 宣言의 國際法的 效果에 관한 硏究

金楨鍵,李載坤 연세대학교 대학원 1988 延世論叢 Vol.24 No.-

In the nuclear Test Case (1974), International Court Justice has recognized the binding effect of French declaration, unilateral in form, based on the fact that it was "given publicly, and with an intent to be bound". In 1947, the military tribunal in Nurmberg cited Hitler's pronouncement that Germany would respect the territorial integrity of Austria and Czechoslovakia as the ground for the indictment. Even earlier, Permanent Court of International Justice recognized the validity of Norwegian Foreign Minister's oral statement, unilateral in character, as a ground for the decision in the Eastern Greenland Case(1932). In international relations, it is not infrequent that governments issue unilateral proclamations or make offers and declarations toward international community in general or toward a specific state in particular. The Egyptian declaration of 1957 regarding its intention pertaining to the operation of the newly nationalized Suez Canal is an example of the former, and the "recognition" of particular state or government is an example of the latter. In examining the legal validity of unilateral or pronouncements, it appears that, in order for a declaration so made unilaterally to have the binding force, it must meet, at minimum, several conditions: (1) that the declaration is made by an entity or authority which, under international law, possesses legal capacity to enter into foreign relations, (2) that the declaration so made is made "publicly", as an expression embodying intent to be bound, and (3) that the target state or entity has utilized the declaration in basing its rights or obligations(explicit or implicit) regarding the respective subject matter. However, inasmuch as the as the declarant state cannot be prevented from withdrawing from the commitment so made unilaterally, it does not follow that declarations made unilaterally are nominally binding. But the fulfillment of the conditions, above stated, would substantially strengthen the case for its "contractual" character.

The piezoresistive acceleration sensors for 50G were fabricated by silicon micromachining method using SDB(silicon direct bonding) wafer. The structure of the piezoresistive acceleration sensor consists of a seismic square pillar type mass and four beams. This structure was fabricated by reactive ion etching and chemical etching using KOH etchant. The rectangular square compensation structure is used in order to compensate the deformation of the edges due to underetching. The fabricated sensors have shown that they have a linear response characteristic to the applied acceleration and their sensitivity is about 88μV/VAT·g from 0G to 10G.

매복치아의 치료는 단순한 관찰에서 외과적 노출후 교정적 견인까지 매우 다양하며, 매복치의 위치 이상이 심한 경우에는 자가이식을 고려한다. 치아의 자가이식술은 맹출되었거나, 매복치아, 변위맹출된 치아 혹은 기능을 못하는 치아를 동일한 개체의 구강내에서 기존의 발치와나 외과적으로 형성한 수용부에 재위치시키는 술식을 의미한다. 자가이식할 치아는 치근장의 ½∼¾ 정도의 치근 발육시기가 치아가 쉽게 발거되고, 합병증이 적게 생기며, 치근의 최종길이가 충분하게 발육한다. 치근 미완성 치아 이식은 무조건 근관치료 하지 않고, 대부분 치수치유를 목표로 하게 된다. 본 증례는 구순열 부위의 과잉치와 함께 상악 우측 중절치의 맹출지연을 주소로 본원에 내원한 환아로, 방사선사진상 상악 우측 중절치와 측절치의 변위매복을 발견하였으며, 치은내 자가이식술을 시행하여 자발적 맹출을 유도, 정상적 치근발육 및 맹출 후 치열의 양호한 배열을 얻을 수 있었다. The treatment method of impacted tooth is various from simple observation to surgical exposure and orthodontic methods, autotransplantation is concerned to severe malposed impacted tooth Autotransplantation is the transplantation of embedded, impacted, of unerupted tooth, into extraction socket of surgically prepared in the safe individual Autotransplantation of tooth with ½∼¾ root development provldes a good chance of easily extracted, a littte complication, pulp survival, and complete root formation. Transplantation of uncompleted root apex tooth is aim to pulpal healing, not endodontic treatment. The case which were treated with autotransplantation is reported, and induced normal physiologic eruption and good dental alignment.

Empirical analysis was performed on the basis of these document research. Target of this analysis are travel agencies that are located in Seoul or have homepage on internet. As it is shown in the result of analysis, that means internet will be general marketing method in tourism agencies and internet will enchance their marketing competitiveness in near future. This study shows internet is significantly related to tourism business, but many tourism companies utilize as a advertisement method and corporate image and it is not used very well in terms of facility or corporate circumstances. In the near future, the importance and efficiency of internet will be increased through generalization of internet and the development of recognition about the importance of mass media.

Purpose : To assess the methods for the clinical evaluation of the longitudinal bone changes after implantation of tooth ash-plaster mixture into the defect area of human jaws. Materials and methods : Tooth ash-plaster mixtures were implanted into the defects of 8 human jaws. 48 intraoral radiograms taken with copper step wedge as reference at soon, 1st, 2nd, 4th, and 6th week after implantation on mixture were used. X-ray raking was standardized by using Rinn XCP device customized directly to the individual dentition with resin bite block. The images inputted by Quick scanner were digitized and analyzed by NIH image program. Cu-equivalent values were measured at the implanted sites from the periodic digital images. Analysis was performed by the bidirectional subtraction with color enhancement and the surface plot of resliced contiguous image. The obtained results by the two methods were compared with Cu-equivalent value changes. Results : The average determination coefficient of Cu-equivalent equations was 0.9988 and the coefficient of variation of measured Cu values ranged from 0.08∼0.10. The coefficient of variation of Cu-equivalent values measured at the areas of the mixture and the bone by the conversion equation ranged from 0.06∼0.09. The analyzed results by the bidirectional subtraction with color enhancement were coincident with the changes of Cu-equivalent values. The surface plot of the resliced contiguous image showed the three dimensional view of the longtudinal bone changes on one image and also coincident with Cu-equivalent value changes after implantation. Conclusion : The bidirectional subtraction with color enhancement and the surface plot of the resliced contiguous image was very effective and reasonable to analyze clinically and qualitatively the longitudinal bone change. These methods are expected to be applicable to the non-destructive test in other fields.(J Korean Oral Maxillofac Radiol 1999;29:423-434)
