정수위수를 갖는 Bessel의 함수에 대한 최적근사

오명호 陸軍士官學校 1989 한국군사학논집 Vol.36 No.-

Bessel함수는 그 유용성 때문에 이공학 전반에 걸쳐 널리 응용되고 있으나, 현재까지는 소형 컴퓨터를 이용한 정확한 해를 구하는 프로그램이 실용화 되어 있지 않은 실정이다. 이 글에서는 소형 컴퓨터를 사용할 시 정수위수를 갖는 Bessel함수에 대한 최적근사다항식을 소숫점아래 열 자리의 정확도로 얻을 수 있는 방법에 대해 살펴보았다. 또한 Bessel함수의 특성상 X의 영역을 두 구간으로 나누어 근사식을 구해야 되는데 7을 두 구간의 경계점으로 선택한 이유에 대해 설명하였다. 최적근사다항식을 얻기 위해 Remes의 제2계산법과 뉴톤의 상차법을 주로 사용하였다.

단부 보강에 따른 U-플랜지 트러스 보의 구조 내력에 관한 실험 연구

오명호,김영호 한국공간구조학회 2020 한국공간구조학회지 Vol.20 No.2

U-flanged truss beam is composed of u-shaped upper steel flange, lower steel plate of 8mm or more thickness, and connecting lattice bars. Upper flange and lower plate are connected by the diagonal lattice bars welded on the upper and lower sides. In this study, the details of delayed buckling of lattice members were developed through reinforcement of the end section, in order to improve structural capacity of U-flanged Truss Steel Beam. To verify the effects of these details, the simple beam experiment was conducted. The maximum capacity of all the specimens were determined by the buckling of the lattice. The vertical reinforced details of the ends with steel plates, rather than the details reinforced with steel bars, are confirmed to be a valid method for enhancing the structural capacity of the U-flanged Truss beam. In addition, U-flanged Truss Steel Beam with reinforced endings with steel plates can exhibit sufficient capacity of the lattice buckling by the formulae according to Korean Building Code (KBC, 2016) and Eurocode 3.

Zernike 다항식을 이용한 Gram-Schidt 방법의 전산화

오명호 陸軍士官學校 1991 한국군사학논집 Vol.41 No.-

ZERNIKE 다항식은 광학분야의 WAVE-FRONT 해석에 대단히 중요한 역할을 하고 있으며 그 특성에 대해서는 이미 잘 알려져 있다. 이 글에서는 소형 컴퓨터를 이용하여 적정 수준의 소수점 이하 오차를 갖도록 ZERNIKE 다항식을 사용한 GRAM_SCJMDT 방법의 전산화에 대하여 살펴보았다. 또한 렌즈 설계를 위한 WAVE-FRONT 해석시 경향성이 무엇보다 중요하지만 최대한 오차를 줄여야 한다는 수치해석학 관점에서 모두 36개인 ZERNIKE 다항식에 상수항을 첨부하여 37개로 만드는 것이 필요하다는 점도 역설하였다. ZERNIKE 계수들을 구하기 위한 서브루틴 GRAMST가 부록에 실려 있다.

바닥 슬래브를 고려한 철골 건물의 내진 거동

오명호,김명한,Oh. Myoung Ho,Kim. Myeong Han 한국방재학회 2013 한국방재학회논문집 Vol.13 No.6

이 논문은 철골조 건물에서 바닥슬래브의 영향을 파악하기 위해 PERFORM 3D의 합리적인 해석모델을 이용하여 기 수행했던 실험결과와 비교하여 해석모델의 신뢰성을 확인하였다. 또한 신뢰성이 검증된 해석모델을 이용하여 10층 사례건물을 대상으로 비탄성정적해석 및 비탄성동적시간이력해석을 수행하여 철골조 건물의 내진성능을 분석하였다. 바닥슬래브는 Fiber Model을 이용하면 철골조 건물의 내진 거동에 반영할 수 있으며, 바닥슬래브로 인해 철골조 건물의 초기 강성 및 최대 강도에 증가하여 철골조 건물의 내진 거동에 영향을 미친다. 그러나 그 영향 정도는 국내 철골조와 같이 접합부가 강하지 않은 경우 크지 않고 국내와 같이 중약진 지역에서는 바닥슬래브의 반영 여부가 철골 건물의 전체적인 내진 거동에 큰 영향을 미치지 않는 것으로 분석되었다. This paper was evaluated the reliability of the analytical model compared the experimental with the analytical results using the Fiber Model of PERFORM 3D to find the effect of the floor slab on the steel building. Then the seismic performance of the steel building was analyzed to perform the nonlinear static analysis and nonlinear dynamic time history analysis on the 10-story case study building. The floor slab could be added the seismic response of the steel building if it was modeled by the Fiber Model and it was affected on the seismic performance because of the incremental effect of the initial stiffness and ultimate strength. But the impact of the floor slab was not critical if the beam-column connection was not strong like the domestic steel building. Thus the addition of the floor slab model was not the important impact on the seismic performance of the steel structure building at the moderate seismic zone.

Steel-concrete composite column is a recently developed composite system, in which the two opposite flanges of H-shape section are connected by welded links, and vacant space enclosed by the flanges, web and links is filled with concrete. The purposes of this paper are to suggest efficient moment-connection details for SC composite column system and to verify their seismic performance. Two types of SC composite column-steel beam connections were proposed; one for strong axis of column and the other for weak axis of column. Cyclic loading tests for two full-scaled specimens were performed according to the standard loading history of SAC(2000). Moment-connection detail for strong axis of column showed sufficient seismic performance required for SMRF(special moment resisting frame). However, connection detail for weak axis of column exhibited inferior seismic performance than that for strong axis of column, which satisfied the requirements for OMRF(ordinary moment resisting frame). Additional studies are needed to increase elastic stiffness and seismic performance of connection detail for weak axis of SC composite column.

第二共和國과 民主的實驗

吳明鎬 한양대학교 사회과학대학 1998 社會科學論叢 Vol.17 No.-

After the downfall of the authoritarian regime of President Rhee Syngmann, a new government based on the parliamentary cabinet system was inaugurated by Premier Chang Myon. There were high hopes for the much-anticipated democratic experiment after years of authoritarian rule. But in the end, Chang's government lasted nine months, only to be overthrown by the Korean military. This study attempts to shed some light on the causes of this short-lived democratic experiment. The beginning of the Second Republic saw a dramatic galvanization of "civil society," which overloaded the political system with a variety of new demands and protests. New progressive political force, joined in by with their radical political stance, particularly in policies concerning the reunification of the divided Peninsula, other ideological issues involving "social democracy," and the nationalization of basic industries. During this transitional period, the mass media mushroomed, and its unbounded criticism stimulated the formation of diverse interest groups and political opposition, and exacerbated the already complex confrontation between diverse political forces. The Democratic Party, which was divided into the Old and New factions, was not successful in absorbing the explosive demands of a newly reactivated civil society. Premier Chang tried to allay the factional strifes by offering cabinet post in three subsequent cabinet reshuffles, but even that produced little tangible results. He met with the political opposition, progressive forces and radical students, with an appeal to "law and order," asking them to give him "time of readjustment," but his appeal only intensified their discontentment. The end of the Second Republic came when the coercive appartuses of the state organization was incapacitated in the early spring of 1961. Faced with growing opposition which manifested in street violence, Chang had to change his hitherto policy of persuasion and appeasement with the opposition. His tougher stance was well demonstrated when he intitiated the legislation of two laws - "Anti-communist law." and "Law regulating demonstrations," which were vitally needed to curb pro-communist activities as well as to stem the radicalization of street demonstrations. However, he failed to get these two laws passed through the National Assembly. Further weakening of the coercive capacity resulted from the punitive measures enforced on the Korean police when the National Assembly passed the law punishing those responsible for rigging the election of March, 1960. About one third of senior officials within the National Police was purged for being involved in so-called anti-democratic practices, which eventually demoralized the entire network of the Korean police. But the final straw that brought down the government occurred when the administration ignored incoming information that a group of military officers was engaged in a conspiracy to overthrow the government. Chang's lack of resoluteness and political leadership became evident when he went into hiding at the pivotal moment of the military coup. Chang surrendered his government to the military on May 16, 1961, without having put up any resistance.
