Korean hemorrhagic fever is a disease that most patients recover without sequelae after clinical course of febrile, hypotensive, oliguric, diuretic and convalescent phases. In the autopsy findings of Korean hemorrhagic fever patients, coagulation necrosis of anterior pituitary gland is known as one of the most characteristic macroscopic findings, but there has been rare reports of panhypopituitarism in patients with Korean hemorrhagic fever. Recently we have experienced panhypopituitarism in two patients who had past history of Korean hemorrhagic fever. First patient, who had Korean hemorrhagic fever 2 and half years ago was presented with chief complaint of sexual dysfunction, Second patient, who had Korean hemorrhagic fever 12 years ago was presented with Addison crisis-like manifestations. Both patients were confirmed as panhypopituitarism by combined anterior pituitary function test. There was no evidence of hypothalamic or pituitary diseases by history and several tests including brain CT scan. Past history of Korean hemorrhagic fever was confirmed by the high titers of antibody against Hantaan virus in patients serum. Our experience shows that Korean hemorrhagic fever can be a cause of panhypopituitarism and high index of suspicion should be maintained to detect hypopituitarism in patients with past history of Korean hemorrhagic fever when appropriate symptoms and signs are present.

직선형 진동모터가 휴대전화의 알림용이나 햅틱 인터페이스의 구동기로 적용되려면 빠른 응답속도와 긴 수명을 제공하여야 한다. 본 논문에서는 기존 직선형 진동모터를 개선하여 보이스 코일 구동기와 영구자석 스프링을 이용한 직선형 진동모터를 제시하고, 설계 제작하여 그 가능성을 검증하였다. Halbach 배열의 영구자석에 의해 구동되는 보이스 코일 구동기와 영구자석 간의 반발력을 이용하는 영구자석 스프링을 해석하고 설계하기 위해, 등가전류판 방법과 이미지 방법을 사용하였고, 방법의 적절성을 유한요소해석을 통해 검증하였다. 시작품 모터를 설계하고 제작하고, 실험을 통해 진동모터의 특성을 확인하였다. In order to use a linear vibration motor for the actuator of a haptic interface, the motor must provide a higher reaction rate and longer service life than typical rotational motors with an eccentric mass. In this paper, we propose a linear vibration motor that is equipped with a voice-coil actuator and permanent-magnet springs. To concentrate the magnetic flux in the actuator, a Halbach-style magnetization pattern is used. Permanent-magnet springs replace mechanical springs to help increase the service life. We use the method of equivalent current sheets and the method of images to analyze and model the proposed vibration motor. These methods are validated using finite element analyses and experiments. A prototype motor is designed and fabricated. Tests with the prototype show the feasibility of the proposed linear vibration motor.

사회복지기관의 후원자재발 마케팅에 관한 연구

최정규 대한경영정보학회 2005 경영과 정보연구 Vol.16 No.-

Most of social service agencies experiences the lack of funds. This situation is casued mainly from the lack of donor development techniques. Therefore, the social service agencies need to develope marketing strategies to develop donors. The study was begun with the idea that a business philosophy will not conflict with professionalism, and the two can be entirely compatible, and synergistic as well. Some of the main principles of marketing can be used to construct a model that will help the social service agency devise the appropriate plan for developing donors. The social service agency's marketing plan should begin with a statement of its mission and goals and the product suggested by each goal. Social marketing process to develop voluntary contributions include marketing environment analysis, market research, selecting marketing goals and objectives, market segmentation, marketing program development, and marketing action. These techniques can be used with some modifications at each social service agency.

Today, the principle of competition is being applied to Non-profit sector also. It is necessary for relevant persons in charge to learn the knowledge and technique about marketing technique endlessly in connection with the development of donor out of the development of social welfare resource which is being embossed as main pending problem at the point of time when the role of private sector about welfare service increased and the criterion of competition and evaluation among institutions was introduced. Especially, as for the application of marketing technique to utilize internet to have big marketing potential, the efforts for the realization and application of positive marketing to be suitable for the real situation of each institution is necessary in connection with the donor development of social welfare institution. In this study tried to examine the charge of method to develop donor which is based on the development of information technique and the popularization of internet from the viewpoint of internet marketing and suggest the basic data about the present situation of donor marketing to use the effective scheme for internet marketing.

A numerical and experimental study on the drag of a cavitating underwater vehicle in cavitation tunnel

최정규,안병권,김형태 대한조선학회 2015 International Journal of Naval Architecture and Oc Vol.7 No.5

For Super-Cavitating Underwater Vehicles (SCUV), the numerical analyses and experiments in a large cavitation tunnel are carried out at relatively large Reynolds numbers. The numerical results agree well with experiments and the drag coefficient of SCUV is rarely changed by the Reynolds number. As the cavitation number is decreased, the cavity occurs and grows, the cavitator drag decreases and the body drag is affected by the degree of covering the body with the cavity. The tunnel effects, i.e. the blockage and the friction pressure drop of the tunnel, on the drag and the cavitation of SCUV are examined from the numerical results in between the tunnel and unbounded flows. In the tunnel, a minimum cavitation number exists and the drag of SCUV appears larger than that in unbounded flow. When the super-cavity covers the entire body, the friction drag almost disappears and the total drag of SCUV can be regarded as the pressure drag of cavitator.

These days the surroundings around harbours are rapidly changing. Particularly in the age of Pacific Rim it is rather clear that the competition among the harbours in Northeast Asia region where are so many of worldwidely famous harbours might be intense. From 1980s on the industrialization and urbanization in the area of Kwang Yand-Bay, thanks to the regional development program, have been speedily under way. And in the year of 1987 the 1st development program of Kwang Yang-Bay container quay was started and is scheduled to be completed by the end of 1997. As the completion of the program it is expected that in 1998 the newly-opening Kwang Yang-Bay container quay on one hand will play a role in relieving the awaiting-time of vessels in Pusan Port, and on the other hand it will contribute to the balanced development of the country. In this context this thesis conducted Its study on the effect of the specification and facilities of a harbour, and especially on the effect on the regional economy resulted by the development & developmental static of Kwang Yang-Bay container quay. And progressively in the thesis the plan to provide Kwang Yang-Bay container quay with competitiveness was suggested.
