  • In the current work, a series of seismic analyses of one-storey asymmetrical reinforced concrete (R/C) framed buildings is accomplished while the effect of soil deformability on the structural response is investigated. A comparison is performed between the simplified elastic behavior of R/C elements according to the structural regulations' instructions to the possible non-linear behavior of R/C elements under actual circumstances. The target of the time history analyses is the elucidation of the Soil-Structure Interaction (SSI) effect in the seismic behavior of common R/C structures by examining the possible elastic or elastoplastic behavior of R/C sections because of the redistribution of the internal forces by employing a realistic damage index. The conclusions acquired from the presented elastic and elastoplastic analyses supply practical guidelines towards the safer design of structures.

  • There are differences in seismic behavior between non-skewed bridges and skewed bridges due to in-plane rotations caused by pounding between the skewed deck and its abutments during strong earthquake. Many advances have been made in developing design codes and guidelines for dynamic analyses of non-skewed bridges. However, there remain significant uncertainties with regard to the structural response of skewed bridges caused by unusual seismic response characteristics. The purpose of this study is performing non-linear time history analysis of the bridges using abutment-soil interaction model considering pounding between the skewed deck and its abutments, and analyzing global seismic behavior characteristics of the skewed bridges to assess the possibility of unseating. Refined bridge model with abutment back fill, shear key and elastomeric bearing was developed using non-linear spring element. In order to evaluate the amplification of longitudinal and transverse displacement response, non-linear time history analysis was performed for single span bridges. Far-fault and near-fault ground motions were used as input ground motions. According to each parameter, seismic behavior of skewed bridges was evaluated.

  • In this study, the seismic analysis of rack structure with fluid-structure interaction is performed through use of the Finite Element Method(FEM) code ANSYS. Fluid-structure interaction can specify in terms of an hydrodynamic effect which is defined as the added mass per unit length divided by the area of the cross section. Using the Floor Response Spectrum(FRS) obtained through the time-history analysis, modal analysis and seismic analysis under Operating Basis Earthquake(OBE) and Safe Shutdown Earthquake(SSE) condition is carried out. The fluid-structure interaction effects on the rack structure are investigated.

  • 개발자들은 소프트웨어 개발과 유지보수 작업 중 하나의 코드를 수정하는데 들이는 시간보다 이를 위해 코드를 탐색하고 이해하는데 더 많은 시간을 소모한다. 코드를 탐색하는 시간을 줄이기 위하여 기존 연구들은 데이터 마이닝과 통계적 언어모델 기법을 이용하여 수정할 코드를 추천하여 왔다. 그러나 이 경우 모델의 학습 데이터와 입력되는 데이터가 정확하게 일치하지 않으면 추천이 발생하지 않는다. 이 논문에서 우리는 딥러닝의 기법 중 하나인 Recurrent Neural Networks에 동작기록을 학습시켜 기존 연구의 상기 문제점 없이 수정할 코드의 위치를 추천하는 방법을 제안한다. 제안 방법은 RNN과 동작기록을 활용한 추천 기법으로 평균 약 91%의 정확도와 71%의 재현율을 달성함으로써 기존의 추천방법보다 코드 탐색 시간을 더욱 줄일 수 있게 해 준다.

  • In this study, a fatigue damage estimation for an ice-going vessel navigating through broken ice fields was carried out. A numerical model to simulate the interaction between ice and structure developed using the finite element method was introduced. Time series of stresses calculated by the proposed model and the corresponding fatigue analysis results are presented. The numerical model enables the long time analysis through an efficient interaction model, the application of the periodic media analysis and the convolution integral, and it allows the stress time history to be extracted directly using the finite element method. To describe the probability distribution of stress amplitudes, the 2-parameter Weibull model was applied to the calculated stress time history, and the fatigue damage was calculated using the Palmgren-Miner rule. Finally, the fatigue damage considering the ice conditions of the Baltic Sea was calculated using the proposed method and LR method, and the results were compared to each other.

  • This study examines the meaning of classical texts in contemporary society. Drawing on an anthropological investigation of Somun Hakhoe, an association of Korean medicine doctors in South Korea, and its foundational text "Somun Daeyo", the present study explores the interconnectedness of medical texts and medico-social practices in bringing medical tradition into the contemporary era. The themes that author Lee Kyu-joon emphasizes in "Somun Daeyo" are thoroughly embodied in Somun Hakhoe's medico-social practices, such as the study activities based on "Somun Daeyo"(in particular, on Somun Buseol, the five articles written by the author, attached to "Somun Daeyo"), the focus on Buyang theory(扶陽論), and the distinctive feature of composing formula. The ethnographic data collected about the group activities of Somun Hakhoe also demonstrate that the social relationship of the teacher and disciples plays an important role in bringing East Asian medicine into the present. This study articulates the significance of the interaction between the classical text and the medico-social practices around it. The dynamism taking place in the interaction points to the "living tradition" actively flowing rather than being static in the past. This study illustrates the close relationship between medical history and medical anthropology and encourages more studies of classical texts based on the intimate relationship between the two disciplines.

  • The purpose of this study was to explore the various perspectives to read micro-history of Korean housing after the period of Opening the Port for foreigners. This study were designed to adapt original theory for exploring the unique housing perspectives without using strict basic assumption which were already developed in the area of sociology, history, anthropology and philosophy. Research method applied was literature review. Each perspective might give useful insight to read the micro-history of Korean housing on the way of change after the Period of Opening the Port in Korea. Adapted perspectives to housing history were critical theory perspective, microsociological perspective, everyday life perspective(phenomenology tradition, symbolic interaction tradition, Marxist tradition), discourse perspective, exchange theory perspective, conflict theory perspective, and life course perspective. Conclusively, each perspective must be adapted multi-supportively to read the housing phenomena, because housing change derived from complex causes and factors. The fruit of this study was to ensure the adaptable viewpoint to housing were useful to read the micro-history of housing change.

  • This paper gives a feminist reading of Suzanne Alexander in The Alexander Plays by focusing on her performances as active reconstitutions of history and memory. A compilation of four of Adrienne Kennedy's more recent plays, The Alexander Plays revolves around a central protagonist who, behind windows and within the closed spaces of the home, waits for her missing husband to return home. Yet, the plot of the waiting wife seems to mask the hidden and more dangerous desires for political transgressions of the play. By analyzing Suzanne's interaction with various literary and historical figures, memories and events, this paper argues that her seeming approval of domesticity, femininity and intimacy serves as a cover for her more political altercations with history, race and gender.

  • There were four academic journals on oriental medicine, published in the era of early Japanese imperialism. Research into these journals has derived the conclusion that the academic trend at the time were, firstly, the interaction between western and eastern medicine, secondly, researches on "Nai Kyung", "Sang Han Ron" and finally, promotion of development of oriental medicine by looking at the advantages of western medicine.
