興宣大院君 內治의 再照明

李玟洙 大邱大學校 社會科學硏究所 1983 社會文化硏究 Vol.2 No.-

Hungsun Dae Won Gun Yi Ha-ung(1820-1898), father of the 26th king, Kojong, of Yi Dynasty, was the well-known Prince Regent. In this paper an attempt is made to consider his achievements he produced while in power. The regent was firm in his resolution and wise in policy-making. Before the regent came to power, the state affairs of Korea had been swayed by the clannish fractions of queens. During his stay in power the Prince Regent repelled the strong influences of the Kim family of Andong which and been regarded as the representative of the nobility for ages, restoring the authority of the king ridden by powerful families. At the same time, he undertook public works on a large scale, one of which was the reconstruction of Kyongbok palace, in order to pursue the political idea of Confucianism elucidating the absolute advantage or royal authority. Of course, the unreasonably forced reconstruction work had unfavorable effects in various respects, but his love for the subjects was sincere. It is said that he used to say, "I will never forgive those detrimental to the welfare of the people, even if Confucius himself came to this world again." He opened the offices to talent or the purpose of doing away with high-handedness of the nobility and stabilization of the people's livelihood. The regent destroyed the memorcial halls for the treat scholars which had become the target of public grievance. As a result, of over 700 halls scattered all over the country only 47 remained. Hungsun Dae Won Gun placed great importance on the national tax revenue and collected taxes from the nobility who had enjoyed the privilege of duty exemption till then, punishing severely corrupt officials who accepted bribes. In addition, he had a body of law readjusted for the establishment of government discipline. The performance of all these policies did have unreasonable side-effects, but his accomplishments should be thought much of. Sometimes the Prince Regent Yi Ha-ung is blamed, as a seclusionist, for having hindered the modernization of Korea by closing door to foreign countries. But it can fairly be said that the enlightenment of Korea grew up during his reign. Without him, the invasion of Korea by foreign powers had been advanced the easier and the earlier.

Crevice Corrosion Evaluation of Cold Sprayed Copper

이민수,최희주 한국방사성폐기물학회 2010 방사성폐기물학회지 Vol.8 No.3

한국원자력연구원 처분시스템개발과제에서는 처분용기 재료로 개발중인 저온분사코팅 구리에 대한 틈새부식(Crevice Corrosion) 시험을 실시하였다. 본 시험을 통하여 틈새에서의 부식의 발생여부와 발생되는 시점인 재부동태 전위(Repassivation Potential)를 측정하고자 하였다. 틈새부식 시험 방법으로 (1) ASTM G61-86 : Cyclic Potentiodynamic Polarization Measurements, (2) SWRI의 PotentiodynamicPolarization plus intermediate Potentiostatic Hold method, 그리고 (3) ASTM G192-08 (THE method) :Potentiodynamic- Galvanostatic -Potentiostatic Method 등의 3가지 방법을 소개하였다. 실제 저온분사코팅구리의 부식시험에서는 ASTM G61-86에 따라서 틈새부식장치를 설치하고, 저온분사 코팅구리가 KURT 지하수를 모사한 용액에서 어떻게 틈새부식이 일어나는지 살펴보았다. 전기적 부식조건으로는 Cyclic Polarization Test, Potentiostatic Polarization Test, 및 Electrochemical Impedance Spectroscopy등을 사용하였다. 그리고 부식이 된 시편에 대해 Profilometer Measurement를 통해 실제 부식표면의 높낮이를 조사하여 틈새부식 유무를 관찰하였다. 최종적인 결론에서는 저온분사코팅구리는 틈새부식을 나타나지 않는다는 것을 확인할 수 있었다. 그리고 시험에 사용된 세종류의 구리에 대한 상대적인 부식평가를 한 결과, 부식전위를 나타내는 개방회로(Open Cell)에서의 전위는 구리의 제조방식과 상관없이 구리의 순도가 높을수록 높은 값을 보이는 것을 확인할 수 있었다. 결론적으로 KURT 심층지하수 조건에서는 구리는 틈새부식이 발생되지 않는다고 결론지었다. The developement of a HLW disposal canister is under way in KAERI using Cold Spray Coating technique. To estimate corrosion behavior of a cold sprayed copper, a creivice corrosion test was conducted at Southwest Research Institute(SWRI) in the United State. For the measurement of repassivation potential needed for crevice corrosion, three methods such as (1) ASTM G61-86 : Cyclic Potentiodynamic Polarization Measurements, (2) Potentiodynamic Polarization plus intermediate Potentiostatic Hold method, and (3) ASTM G192-08 (THE method) : Potentiodynamic- Galvanostatic-Potentiostatic Method, were introduced in this report. In the crevice corrosion test, the occurrence of corrosion at crevice area was optically determined and the repassivation potentials were checked for three kind of copper specimens in a simulated KURT underground water, using a crevice former dictated in ASTM G61-86. The applied electrochemical test techniques were cyclic polarization, potentiostatic polarization, and electrochemical impedance spectroscopy. As a result of crevice corrosion tests, every copper specimens including cold sprayed one did not show any corrosion figure on crevice areas. And the open-cell voltage, at which corrosion reaction initiates, was influenced by the purity of copper, but not their manufacturing method in this experiment. Therefore, it was convinced that there is no crevice corrosion for the cold sprayed copper in KURT underground environment.

단극성 및 양극성 정서질환의 망상과 환각에 대한 임상적 고찰

이민수 大韓神經精神醫學會 1981 신경정신의학 Vol.20 No.2

In this study, the author reported on the various clinical characteristics of 49 unipolar and 98 bipolar patients who were diagnosed as the manic depressive illness and visited the neuropsychiatric department of Korea university hospital during the period from January, 1977 to February, 1980. This study was to investigate phenomenologically the frequency and characteristic nature of delusions and hallucinations seen in the above subjects. An additional attempt was made to ascertain the clinical differences between these two groups for which other authors reported. The mean age at the onset of the unipolar illness was 30.8 years old, ranging from 16 to 35 years and the mean age of the bipolar illness was 25.3 years old, ranging from 15 to 54 years. The number of females were 1.6 times greater than males in the unipolar, and 2.3 times greater in the bipolar patients. Bipolar patients had higher academic achievement than unipolar patients and both groups came from socioeconomically upper-middle class, and no significant difference of the religious background was found between these two groups. The married were seen more common in the unipolar than the bipolar. Depressive personality was found most frequently in the unipolar, and cyclothymic one in the bipolar. In the family history, the bipolar had more positive history of affective illness in the first degree relatives than the unipolar. In ordinal position of the siblings, the greatest number was the middle born in both groups. Twelve patients of the unipolar and 21 patients of the bipolar had history of parental loss by death, divorce or separation before they reached the age of 13 years and the frequency of the loss was similar in both groups 24.6% in the unipolar and 21.3% in the bipolar group. The precipitating factors, such as death, loss, separation and other stressful life events were accounted for 31.3% of the total patients. Delusions occurred in the rate of 42.9% of the total patients and were seen in the rate of 66.7% of the bipolar manic and 27.8% of the depressive in both the bipolar and unipolar. According to the themes of delusions, grandious natures were ween most frequently in the manic, and persecutory ones in the depressive. Among the grandious delusions, political delusions were highest in males and religious ones in females. Hallucinations occurred in the rate of 6.1% of the total patients. Among these, auditory hallucinations were seen most frequently.

이민수,추연규,이광석,김현덕,박연식 한국정보통신학회 2003 한국정보통신학회논문지 Vol.7 No.7

선박 자율운항 시스템은 운항 안전성 확보, 운항능률의 향상, 선내 노동력 감소 및 작업환경 개선에 목표로 두고 있으며, 궁극적으로는 운항 경제성 확보를 통한 승선 인원의 최소화에 그 목적이 있다. 최근에는 적응제어방법 등을 응용하여 선박의 다양한 비선형성을 보상하고 선박의 회두각 유지제어, 항로 추적제어, 롤-타각제어, 선박 위치제어, 선박 자동접이안 등의 분야에 관한 연구가 수행중이며 실제 선박을 대상으로 한 응용연구가 진행 중에 있다. 선박의 Steering Machine에 의해 조정되는 Rudder angle과 선박의 회두각의 관계와 Load Condition은 선박운항 파라메터에 영향을 주는 비선형적인 요소로서 작용한다. 또한 외란 요소인 파도의 유속과 방향, 풍속과 풍량 등은 선박의 운항을 힘들게 하는 주요 요인이 된다. 따라서 선박 자율운항 시스템에는 다양한 비선형성을 극복할 수 있는 강인한 제어 알고리즘을 필요로 한다. 본 논문에서는 퍼지 알고리즘을 이용하여 선박의 비선형적인 요인 및 외란을 극복할 수 있는 선박 자율운항 시스템을 설계하고 시뮬레이션을 통행 제안된 알고리즘의 우수성을 확인하였다. The autopilot system of vessel is proposed to take service safety and security, to elevate service efficiency, to decrease labor and to improve working environment. Ultimate purpose of the proposed system is to minimize the number of crew by guaranteeing economical efficiency of shipping service. Recently, the research is being achieved to compensate various nonlinear parameters of vessel and apply it to course keeping control, track keeping control, roll-rudder stabilization, dynamic ship positioning and automatic mooring control etc. using optimizing control technique. Relation between rudder angle controlled by steering machine of vessel and ship-heading angle, and load condition of ship is nonlinear, which affects various parameters of shipping service. The speed and direction of waves, velocity and quantity of wind, which also cause the non-linearity of it. Therefore the autopilot system of ship requires the robust control algorithm can overcome various non-linearity.
