강주원,남윤경,Kang, Ju-Won,Nam, Younkyeong 한국과학교육학회 2017 한국과학교육학회지 Vol.37 No.4

The purpose of this study is to investigate how engineering design-based STEM research experience affects gifted students' creative engineering problem-solving propensity and attitude toward engineering. The students' creative engineering problem-solving propensity and attitude toward engineering were measured before and after the STEM research experience. The pre-/post-tests results were analyzed by paired t-test with the significance level of p <.05. The conclusions of the study are as follows: First, the engineering design based STEM research experience had a positive effect on the students' creative engineering problem-solving propensity. Over all, the average score of the creative engineering problem-solving propensity increased significantly (p <.05) after the STEM research experience. Second, the average score of gifted-students' attitude toward engineering had increased significantly after the integrated STEM research activities (p <.05). In addition, we analyzed the difference between pre-post results of both instruments based on the gifted students' desired career paths (natural science and engineering) and gender. The result shows that the students' career paths or gender did not affect the results in most of the sub-categories in both instruments. However, the STEM research experience had more positive effect on the female students than male students in term of their 'engineering design ability', which is one of the sub-categories of the creative engineering problem-solving propensity instrument.

[특집] 4년제 건축공학교육과 ABEEK 인증

강주원 대한건축학회 2003 建築 Vol.47 No.7

21세기 세계화 정보화 시대를 맞이하여 우리는 커다란 변혁을 겪고있다. 산업사회에서 정보화사회로의 이전, 높아지는 선진국의 기술보호 장벽과 시장 및 교육개방 압력 등이 그것이다. 이러한 상황에서 우리나라가 생존하고 발전하기 위해서는 이들 국가들과 치열하게 경쟁해야만 하며, 이를 위해서는 창의력과 기술경쟁력의 확보가 무엇보다도 중요하다고 할 것이다. 이는 미래지향적이고 창조적인 건축공학도를 양성해야한다는 문제로 귀결되며 이것이 오늘날 우리 건축계에 맡겨진 중대한 소명이라 하겠다. 이러한 시대적 요구에 따라 공학교육 개혁의 중요성은 새삼 강조할 필요가 없다고 생각된다.<br/> 이에 따라 우리나라에서는 한국공학교육인증원(ABEEK :Accreditation Board for Engineering Education of Korea)을 설립하여 공학교육에 대한 국제 표준화 작업 및 이와 관련된 정량적인 평가와 인증 등, 공학교육의 기반을 확립하기 위한 여러 가지 노력을 경주하고 있으며 엔지니어 자격을 국제적으로 상호 인정하는 워싱톤 협약에 가입하기 위해 기준을 마련하고 있다. 현재 2001년 영남대학교와 동국대학교의 시범인증을 시작으로 2002년에는 울산대학교의 정식인증 등, 공학교육 인증신청이 점진적으로 증가하는 추세에 있다.<br/> 본 고에서는 국내 공학교육인증 제도 및 기준, 그리고 ABEEK인증을 위해 영남대학교 건축학부에서 개편한 4년제 건축공학교육을 소개하고자 한다.

강주원 대한건축학회지회연합회 2020 대한건축학회연합논문집 Vol.22 No.4

아웃리거 댐퍼 구조시스템은 기존의 아웃리거 구조 시스템의 동적 제어성능을 향상시키고 기존 원안에 대비하여 물량을 저감시켜 경제적인 설계를 할 수 있다. 본 연구에서는 아웃리거 댐퍼 구조시스템이 적용된 고층구조물의 동적응답분석과 물량저감에 따른 동적 응답 제어효과에 대한 해석적 연구를 수행하였다. 해석모델의 종류는 전단벽 구조시스템, 아웃리거 구조시스템, 아웃리거 댐퍼 구조시스템으로 모델링 하였다. 시간이력해석방법을 사용하여 최상층 변위응답과 가속도응답을 비교해 본 결과 해석모델 중 아웃리거 댐퍼 구조시스템의 동적응답이 가장 저감 되었다. 또한, 아웃리거 댐퍼 구조시스템의 물량저감에 따른 동적응답을 분석하기 위해 코어벽체의 두께, 아웃리거 부재의 크기, 아웃리거 부재와 연결된 기둥 크기를 변화시켜 해석하였다. 그 결과 코어벽체의 두께를 변화시킬 때 가장 효과적이며, 물량저감 효과 또한 가장 높았다. Outrigger damper structure system improves dynamic response control performance of existing outrigger system and can be designed economically by reducing quantity compared to existing original plan. In this study, a high-rise building with an outrigger damper structure system was modeled to perform dynamic response analysis and an analytical study on the dynamic response control effect according to the quantity reduction. Structure type of analytical models were the shear wall-frame structure system(NOR), the outrigger structure system(OR) and the outrigger damper structure system(ORD). As a result of comparing the maximum displacement response and acceleration response of the top floor using the time history analysis method, the dynamic response of the outrigger damper structure system has been greatly reduced. among analytical models. it was also analyzed by changing the thickness of the core wall, size of the outrigger member and size of the column connected with outrigger member to analysis dynamic response according to quantity reduction of the outrigger damper structure system. As a result, the response reduction effect was more effective as the thickness of the core wall was changed. In case of quantity reduction effect as changing the cross section of the core wall, the quantity reduction rate was also the highest.

Fuzzy hybrid control of a wind-excited tall building

강주원,김현수 국제구조공학회 2010 Structural Engineering and Mechanics, An Int'l Jou Vol.36 No.3

A fuzzy hybrid control technique using a semi-active tuned mass damper (STMD) has been proposed in this study for mitigation of wind induced motion of a tall building. For numerical simulation, a third generation benchmark is employed for a wind-excited 76-story building. A magnetorheological (MR) damper is used to compose an STMD. The proposed control technique employs a hierarchical structure consisting of two lower-level semi-active controllers (sub-controllers) and a higher-level fuzzy hybrid controller. Skyhook and groundhook control algorithms are used as sub-controllers. When a wind load is applied to the benchmark building, each sub-controller provides different control commands for the STMD. These control commands are appropriately combined by the fuzzy hybrid controller during realtime control. Results from numerical simulations demonstrate that the proposed fuzzy hybrid control technique can effectively reduce the STMD motion as well as building responses compared to the conventional hybrid controller. In addition, it is shown that the control performance of the STMD is superior to that of the sample TMD and comparable to an active TMD, but with a significant reduction in power consumption.

다목적 유전자알고리즘을 이용한 스마트 TMD의 퍼지제어

강주원,김현수,Kang, Joo-Won,Kim, Hyun-Su 한국전산구조공학회 2011 한국전산구조공학회논문집 Vol.24 No.1

In this study, an optimization method using multi-objective genetic algorithm(MOGA) has been proposed to develop a fuzzy control algorithm that can effectively control a smart tuned mass damper(TMD). A 76-story benchmark building subjected to wind load was selected as an example structure. The smart TMD consists of 100kN MR damper and the natural period of the smart TMD was tuned to the first mode natural period of the example structure. Damping force of MR damper is controlled to reduce the wind-induced responses of the example structure by a fuzzy logic controller. Two input variables of the fuzzy logic controller are the acceleration of 75th floor and the displacement of the smart TMD and the output variable is the command voltage sent to MR damper. Multi-objective genetic algorithm(NSGA-II) was used for optimization of the fuzzy logic controller and the acceleration of 75th story and the displacement of the smart TMD were used as objective function. After optimization, a series of fuzzy logic controllers which could appropriately reduce both wind responses of the building and smart TMD were obtained. Based on numerical results, it has been shown that the control performance of the smart TMD is much better than that of the passive TMD and it is even better than that of the sample active TMD in some cases.

Behcet씨병에 의한 혈관합병증

강주원,임근우,고용복,유승진 대한혈관외과학회 1989 Vascular Specialist International Vol.5 No.1

Behcet's disease is a systemic disease with multiple clinical manifestations, the basis of which is a vasculitis. The most common cuase of death in Beh qets disease is secondary to arterial complication. The pathogenesis of arterial complication is related to involvement of the arterial wall or vasa vasorum by the Behce'ts disease process. Because the disease is systemic, it is conceivable that multiple vessels in the same patient could be affected over a short period. Therefore, early diagnosis and aggressive management can result in long-term salvage of both limbs and may allow early intervention for arterial complication and prevent the usual fatal outcome. We report our experience of four patients with Behcets disease who developed multiple arterial complications.
