Background : In recent years, gonorrhea has been panedemic and remains one of the most commom 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 VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

The estimation of unit delivery costs plays an important role in the design of a physical distribution system. Delivery costs depend on the vehicle routes. In order to estimate delivery costa the total length of vehicle routes should be estimated beforehand. In this paper a simple formula estimating the length of vehicle routes is presented. The length formula is a modified version of Daganazo(1984)'s. The capacity of each vehicle type and the demand quantity of each customer served by a distribution center are reflected to that formula. And also a formula to estimate the unit delivery cost is developed by using the length formula. The unit cost formula can be widely applied to the design problem of a complicated multistage physical distribution system.

The purpose of this study was to evaluate the marginal fitness of Nickel-Chrome alloys to various phosphate investments. A copper die and its negative were machined to fabricate same wax pattern. Completed wax pattern was invested, burnt-out and cast as scribed by the manufactures of the respective investment materials. After sandblasting, each metal coping was cemented to a stone die which was duplicated the copper die with finger pressure. Each cemented die-coping assembly as embedded with self-curing acrylic resin and sectioned along the midline of occlusal surface with diamond disk and measured the margin with microscope. The reslut could be summerized as follows: Mean marginal discrepancies of Unitbond to Hi-Temp was 99μ, to Ceramigold was 116μ and to Biovest was 141μ. Mean marginal discrepancies of Talladium to Hi-Temp was 53μ, to Ceramigold was 81μ and to Biovest was 106μ. Mean marginal discrepancies of Rexillium Ⅲ to Hi-Temp was 57μ, to Ceramigold was 100μ and to Biovest was 82μ. Mean marginal discrepancies of verabond to Hi-Temp was 59μ, o Ceramigold was 87μ and to Biovest was 102μ. Mean marginal discrepancies of Unibond to Hi-Temp was 146μ, to Ceramigold was 126μ and to Biovest was 149μ.

The vehicle requirement planning in a company is very important not only for the stable procurement of vehicles in order to supply goods to its customers at right times and at right places, but also for the compilation of logistics budget. The purpose of this paper is to suggest a systematic approach to establish the requirement planning for the full load vehicles. Since the algorithm developed here is based on the historical vehicle routes information, the vehicle requirement planning that is close to reality can be prepared.

The purpose of this paper is to suggest the optimal policy for determining the waiting position of automated guided vehicles according to the specific situations in a flexible manufacturing system. The waiting positions play an important role for the efficient utilization of vehicles. Three waiting policies are compared in terms of total waiting time, total number of parts waiting in system, average number of parts transported per vehicle. Those criteria are evaluated under various conditions by using SLAMSYSTEM.

Brushless 同期發電機의 特性에 關한 硏究 : 主로 自勵型 Brushless 單相同期發電機의 應用에 對하여

As an excitation system of the synchronous generator, an exciter which is directly connected to the main shaft, comprising some restrictions by the increasing capacity under the condition of commutation, has generally been used. In order to solve the restriction problem as well as to operate the generator without difficulty, it is desired to get rid of electrical sliding contacts such as brush and slip ring. To eliminate these electrical sliding contacts, several types of brushless generators have been developed, one of which being understood to be the self-excited brushless single-phase synchronous generator. In this paper, the results of experimental test about the characteristics are analyzed. There are not a few possibilities in the CT connection wherein the load current affects the exciting current.

복수 설비보전센타의 복수정차 입지문제

宋省憲 弘益大學校 1988 弘大論叢 Vol.20 No.2

In many maintenance services the maintenance unit usually visits a number of demand points in a single tour. The multistop location problem is to find the depot location for the maintenance unit. We focus on locating p depots in a specified region where numerous demand points requiring maintenance services are scattered. We call it the multistop location problem of multiple facility maintenance centers. The method proposed here for the above problem can be uesfully applied to the situations where the service time performing maintenance operation is relatively short and the demand points are densely located in small area.

특수교육지원센터 치료지원서비스에 대한 견해 : - 작업치료 서비스를 받는 보호자를 중심으로 -

송민옥,이성자,김훈주 대한감각통합치료학회 2010 대한감각통합치료학회지 Vol.8 No.1

목적 : 본 연구에서는 특수교육지원센터에서 시행되는 치료지원서비스의 인식, 목적, 특징 및 개선방안을 살펴봄으 로써 치료지원서비스의 전반적 실태를 파악하고 이를 통해 최적의 치료지원서비스를 제공하기 위한 기초자료로 제시하고자 한다. 연구 방법 : 현재 특수교육지원센터에서 치료지원서비스를 받고 있는 치료지원대상 아동의 보호자를 대상으로 개별 인터뷰가 진행되었다. 인터뷰는 평균 40분이 소요되었으며, 모든 인터뷰는 녹취되었다. 결과 : 치료지원서비스에 대한 근본적인 인식이 부족하였고, 치료영역의 전문가가 치료를 담당함으로 인하여 치료사에 대한 신뢰도가 높은 것으로 조사되었다. 또한 치료실의 시설 및 교재교구의 다양성으로 인해 질적으로 높은 치료를 받는다고 생각하고 있었으며 모든 연구대상자는 무상교육을 치료지원서비스의 특징으로 꼽았다. 결론 : 작업치료사가 특수교육지원센터에서 치료지원서비스 전문가로 자리 매김하기 위해서 많은 노력과 연구 및 대외적인 홍보가 필요하다. Objective : The purpose of this study is to provide practical guidelines for the better performance of the Occupational therapy services(OT services) in the Supporting Center for Special Education. The study is based upon the quality and satisfaction of the OT services, measured by interviewing parents whose children have taken the services provided by Ulsan Kang-Nam Supporting Center for Special Education. Methods : Five parents for the children having OT services since March, 2010 in the Kang-Nam Supporting Center were interviewed individually. The interview per each person took thirty to fifty minutes and was all audio-recorded. Results : The satisfaction of the qualification for the OT therapists working at the Kang-Nam Supporting Center was high. The quality for treatment facilities and the variety for treatment materials met the expectation for OT to be well-performed. The free OT treatment system was the one of significant features for the OT services provided by the Kang-Nam Supporting Center. However, the perception of the interviewed parents for the OT was very low.

수학 영재를 위한 교수 원리 및 방법의 적용에 대한 小考

송상헌 仁川敎育大學校 科學敎育硏究所 2002 과학교육논총 Vol.14 No.-

수학 영재를 위한 교수법에서 강조되어야 할 것은 기성의 수학 내용 이해를 위한 지식의 전달보다는 새로운 내용으로의 발전과 창조적 경험을 해 볼 수 있는 기회를 제공하는 것이다. 따라서 수학의 내용과 방법에 대한 수학적 사고를 유발하고 그 사고를 이끌어 낼 수 있는 수학적인 태도가 형성되도록 안내하는 교수법이 되어야 할 것이다. 이 글은 수학 교수 원리와 방법의 실제를 개관한 뒤, 테트리스라는 게임을 탄생시킨 ‘테트로미노’ 조각 퍼즐에서부터 최근 공간감각 신장을 위해 소개되고 있는 ‘소마큐브’라는 퍼즐의 탄생에 이르기까지의 과정을 발생적 원리에 따라 재구성하면서 활동적 원리에 따른 교수방법의 실제를 소개한다. 특히, "What if ~?”라는 발문 기법을 활용한 교수법과 안내된 재발명의 교수법을 적용하여 수학 영재들에게 기존의 퍼즐을 해결하는데 머물지 않고 창조적인 산출물을 만들어 낼 수 있도록 안내하는 구체적인 방법을 시연하면서 창조는 생각을 바꾸는 것에서부터 시작됨을 강조한다. For the mathematically gifted student, it is more important giving the experience for developing and creating the new subject contents than giving the already created knowledge. So the teaching method for the gifted student is to elicit mathematical thinking and mathematical attitude. In this paper, I suggested a concrete example for which guided re-invention method based on the both active and genetic principles, with ‘what if?’ and ‘what if not?’ technique to the histories from ‘tetrominoes’ puzzle to the ‘soma cube’ puzzle. I am emphasizing not on solving the puzzles but on recreating them with their constructed principles.

분할배달을 고려한 발견적 배송경로 결정 방법

This paper considers the Vehicle Routing and Schedule Problem with numerous features added in an attempt to model more realistic problems. These features include the following possibilities : a delivery to a customer is permitted to be made by more than one vehicle; customers have a time interval, or intervals, in which their delivery must be made(i. e. a time window); a vehicle type by a demand situation and available travel time per day. We proposed two heuristics: the first one uses a saving-insertion method and the second one uses a saving method. For comparsion, two of our route development methods are implemented on a specifically developed data set.
