The progressive collapse analysis of reinforced concrete (RC) moment-frame buildings under extreme loads is discussed from the perspective of modeling issues. A threat-independent approach or the alternate path method forms the basis of the simulations wherein the extreme event is modeled via column removal scenarios. Using a prototype RC frame building, issues and considerations in constitutive modeling of materials, options in modeling the structural elements and specification of gravity loads are discussed with the goal of achieving consistent models that can be used in collapse scenarios involving successive loss of load-bearing columns at the lowest level of the building. The role of the floor slabs in mobilizing catenary action and influencing the progressive collapse response is also highlighted. Finally, an energy-based approach for identifying the proximity to collapse of regular multi-story buildings is proposed.

인류의 문화 전반이 과학기술의 발전에 따른 뉴미디어들로 인해 급격한 변혁을 맞이하고 있다. 대중들의 보편적인 사고방식도 언어적인 것에서 영상적인 것으로 바뀌고 있다. 이러한 상황 속에서 영상언어로서 영상을 이해하는데 중요한 역할을 하는 시점(視點)에 대한 깊이 있는 연구가 필요하다. 본 연구자는 기존 제도 교육이 서양의 원근법에만 한정되어 다양한 애니메이션 시점을 확보하지 못했다고 느끼고 한국적인 시점을 찾아보고자 하는 관심에서 시작되었다. 시점적 자율성을 가지고 있는 민화의 다시점은 관념의 공간안에서 다양하고 자유롭게 전개되어 하나의 대상을 완전하게 구성하려는 한국의 전통적 표현방식으로 한국적인 정서에 맞는 시점을 제안하는 것이 연구의 목적이다. 본 논문을 통해 먼저 민화의 개념 및 특징을 파악하고 민화 관련 사례연구를 통해 한국 애니메이션의 특성에 맞는 한국 민화의 다시점을 활용한 시각적 표현구조를 연구하고자 하였다. 이를 바탕으로 한국 민화의 다시점을 디지털 미디어환경에서 느낄 수 있도록 전래동화 '해님달님'을 한국 민화의 다시점에 적용하여 애니메이션으로 재구성하였다. 작가의 관념의 공간 안에서 표현되는 여러 가지 표현법 중에 평원(平遠), 부감(府瞰), 역원근(逆遠近),동시적 표현법(同時的 表現法)의 4가지 방식을 활용하여 작품에 적용하였고 시점적 측면에서는 천(天)과 지(地)를 상징하는 호랑이와 새의 캐릭터를 작품에 적용하였다. 또한 화면구성방식은 실재(實在) 민화를 사용하여 이미지를 분해하고 스토리텔링에 맞게 재구성하였다. 본 연구자는 이러한 연구와 제작과정에서 얻은 결과를 바탕으로 관객에게 보다 다양한 시점을 제공하고, 한국 민화의 다시점이 애니메이션뿐만 아니라 다른 콘텐츠들을 통해 확장될 수 있는 가능성을 제안하고자 하였다.

A multi-screen environment provides a new opportunity for digital signage applications, where various irregularly shaped screens are employed as an effective means for advertisements and information. A formation method applicable to numerous irregularly shaped screens is proposed to provide a new perspective on digital signage applications. The crucial part of the proposed method comes from the geometric sensing of each screen and the formation of a virtual screen where geometrically aligned content extraction and encoding are employed for content transmission to each screen. In addition, a software-based synchronization method for the proposed system is proposed to address the frame-level synchronization between screens. The experimental results of the proposed method show an improved performance of the frame-level synchronization, where the inconsistency between frames is not identified.

이 글은 지속 가능한 기술을 위한 정책적 도구로서 전략적 니치관리(Strategic Niche Management)를 개괄하고, 그 효용과 한계를 점검하고 있다. 전통적인 접근인 시장실패론적 접근과는 달리 전략적 니치관리의 접근은 시스템적 접근으로서, 다층적 관점(Multi Level Perspective)를 통해 기술혁신과 변화를 재분석해내고, 고착화된 사회 기술시스템의 전환을 이룩해내기 위한 방법론이다. 전략적 니치관리의 이론적, 경험적 미성숙에도 불구하고, 전략적 니치관리는 기술혁신과 발전에 대한 분석 틀로서 뿐만 아니라, 급진적 혁신을 만들어 낼 수 있는 도구로서의 가치가 주목된다. 노령화 사회에 대비한 혁신정책 및 지속가능한 에너지 시스템 구축을 위한 혁신정책, 위험사회에 대응한 혁신정책들이 새로운 혁신정책의 영역으로 부상하고 있는 상황에서 전략적 니치관리는 이들 분야에서 중요한 분석 및 실천도구로 활용되며 새로운 영역을 개척할 수 있을 것으로 기대된다.

Technology for electric lighting has been evolving from Incandescent Lamp(IL) through Fluorescent Lamp(FL) and currently to Solid State Lighting(SSL) such as LED for more than 130 years of time. However, it took more than 100 years until the transition from IL to FL across overall society. That is because the transition is the Socio-Technical Transition(STT) which involves various social elements. This study investigated and analyzed the theories regarding STT, and applied the Multi-Level Perspective(MLP) theory to the case of electric lighting. A qualitative contents analysis was used with secondary data as research method, and the analyzed result was visualized based on the frame of MLP theory. The STT of electric lighting from IL to FL took place as the order of Technical Niche, Socio-Technical Regime and Landscape. Specifically, in Technical Niche level: Establishing Market Niche, Price-Performance Improvement, Learning Process and Support of Powerful Group took place. In Socio-Technical Regime level: Changes in Social Network, Changes in Technology and Changes in Rules. In Landscape level: Macro-Political Development, Socio-Economic Trends and Macro-Economic Trends took place in consecutive order.

A process of 3-D particle image velocimetry, called here, as '3-D stereo PIV' was developed for the measurement of a section field of 3-D complex flows. The present method includes modeling of camera by a calibrator based on the homogeneous coordinate system, transfromation of oblique-angled image to transformed image, identification of 2-D velocity vectors by 2-D cross-correlation equation, stereo matching of 2-D velocity vectors of two cameras, accurate calculation of 3-D velocity vectors by homogeneous coordinate system and finally 3-D animation as the post processing. In principle, as two frame images only are necessary for the single instantaneous analysis of a section field of 3-D flow, more effective vectors are obtainable contrary to the previous multi-frame vector algorithm. An experimental system was also used for the application of the proposed method. Three analog CCD cameras and an Argon-Ion Laser(300mW) for illumination were adopted to capture the wake flow behind a bluff obstacle.

As various types of information technology systems are becoming more pervasive than ever, many studies have evaluated the systems from the user perspective. Some of them have used surveys to measure consumers' cognitive responses to the target technology. However, this method may cause problems if the survey participants do not have a useful frame of reference for evaluating an unfamiliar system. To examine this issue, the current study empirically tested the effect of personal product knowledge on the predictability of a behavioral model, such as Technology Acceptance Model. A series of measurement invariance tests as well as multi-group comparison tests were conducted for rigorous examination of the data. Our analysis showed that the variance of attitude that is explained by the two believes (perceived usefulness and ease of use) was relatively small when the survey respondents had lower amount of product knowledge. Moreover, the group had weaker causal relationship between attitude and intention to use the technology, hindering the predictability of the research model. The results indicated that respondents should have a certain amount of knowledge of the target system in order to form accurate beliefs and behavioral decisions. The findings of this study provide important implications on sampling strategies for researchers with new technology.

Purpose: This study aims to verify the effects of omnichannel characteristics on pleasure, resistance and repurchase intention in the omnichannel situation in order to provide the innovative commercial business. Research design, data and methodology: The study examined relations between research concepts centered on previous studies, set hypotheses, developed a research model, and verified the model through a questionnaire survey. A total of 297 questionnaires were used for the final analysis, excluding the questionnaires showing insincere or outliers. Results: First, Omnichannel showed multi-dimensional characteristics consisting of consistency, innovation, economy, and integration. Second, innovation and economic feasibility had a positive effect on pleasure. Third, only economic feasibility had a negative effect on user resistance. Fourth, consumers' shopping pleasure had a negative effect on user resistance. Fifth, repurchase intention of consumers was positively affected by innovation. Conclusions: This research contributed to extend academic framework of distribution research by examining causal relationship through adoption of economic and innovation factors as new characteristics from the integrated perspective beyond the research frame of the existing omnichannel distribution environment. Companies should provide meaningful experiences by resolving concerns about side effects caused by human-computer interaction and providing smart information that matches the products most suitable for consumer needs.
