섭동계수를 갖는 저차특성방정식의 안정도 해석에 관한 연구
노장주,박한석 한국산업안전학회 1992 한국안전학회지 Vol.7 No.4
연속적이고 선형적인 시스템의 특성방정식에 대한 안정도 해석을 본 연구에서 제시한 간단한 조건들에 의하여 판정할 수 있으며, 이들 조건들을 이용하여 저차 특성방정식(N≤5)의 계수들이 안정도를 유지하면서 얼마만큼 섭동할 수 있는가를 보여준다. 이 결과는 Kharitonov조건과 Hermite-Biehier 정리를 이용한 Anderson등의 결과와 유사하다. It is shown that for a characteristic equation of continuous linear system, stability can be determined by conditions suggested in this paper. And also it is of interest to Know how much coefficients of the low-order characteristic equation(N≤5) can be perturbed while simutanously preserving the stable condition of the equation. This result is analogous to result by Anderson et al. based on the Kharitonov's conditions and Hermite-Biehler theorem.
한국해기사의 교육개발에 관한 연구 (한국해양대학 승선학과교육의 발전과제)

In Korea, the importance of keeping the see transportation facilities and well-trained maritime officers cannot be overemphasized, because of her geographical location and the national security in terms of both political and economical situations. In this paper, some points are suggested for the development of the nautical education in Korea Maritime University: (1) the strict regimental training should be kept as a vital important part of students life and its program should be designed to provide students with leadership training and experience, and to develope in the qualities of responsibilities for good citizenship and self-discipline to overcome hardwork for careers as leaders in Korea maritime industry. And therefore the dormitory and training vessel as essential parts of the educational facilities should be improved both in quality and quantity, (2) the undergraduate course should be extended to more than 5 years so that accredited baccalaureate curriculum and licensing professional education might be well conducted to meet the requirements to cope with the international competition in the facet of seafarers quality, (3) more enlarging the opportunities of incentive payments for students is required so that better qualified applicants can be admitted, (4) finally, a conjugal maritime officer service system should be put into practice in the foresseable furture so that seafarers might live normal family lives while staying at sea.
