The influence of bi-directional earthquake-induced loading on eccentric (plan-asymmetric) building systems has been investigated. In the first part of the study, comparisons have been made with equivalent results from uni-directional studies. The results are important in developing analytical models appropriate to the formulation of design recommendations. It is concluded that for valid comparisons, both perpendicular horizontal earthquake components must be considered when using models with transversely-orientated elements. In the second part of the study, an assessment has been made of a simplified, unidirectional (lateral) design approach. For stiffness-eccentric systems, the latter approach gives accurate and reasonably conservative estimates of the critical flexible-edge deformation, but may under estimate the stiff-edge element ductility demand by a factor of two in the short-period range.

London Convention on the prevention of marine pollution by dumping of wastes and other matter prohibits the deliberate disposal of paper mill sludges at sea. In order to explore the alternative plan on the prohibition of sludge disposal at sea, the biodegradable seedling pot was developed by mixing the sludge with old newspaper (ONP) in appropriate mixing ratios. The C/N ratio of the mixed sludge was below 20, leading to rapid deterioration of the organic matters composing the seedling pot. The increased ONP contents in the seedling pot resulted in the increase of pot thickness and thereafter in the decrease of pot density. Cellulose fibers in ONP promoted water absorption of the pot but AKD addition helped the seedling pot to repel water during raising seedling. Breaking length and burst strength of the seedling pot were improved by addition of wet strength additives but air permeability was a little diminished. Biodegradable rate of the seedling pot in a soil was accelerated by the attack of soil microbes at the beginning, and finally the pot was completely degraded in 150 days in a soil.

디지털 매체의 발달과 교육에 대한 관심은 전 세계적으로 디지털 교육디바이스의 발전을 가져왔다. 교육 선진국인 영국은 전자 칠판, 전자 책상 등 다양한 디지털 교육 매체를 활용하고 있고 일본은 Ditt 액션 플랜을 계획하여 디지털 교과서를 국가적 차원에서 투자 발전시키고 있다. 인터넷 선진국인 한국의 경우는 2007년 수학 디지털 교과서를 시작으로 과학교과서를 거쳐 2010년 영어 공교육강화 정책이 시행되면서 2011년 영어디지털 교과서가 국가 정책의 일환으로 도입 되었다. 빠르게 디지털 교육매체를 받아들이고 발전시키고 있는 과도기적 시점에서 효율적인 교육 효과와 디자인 가이드의 설립을 위하여 디지털 교육 선진국의 디지털 교과서 및 교육 매체의 적용 사례연구를 통한 장단점을 분석하여 한국 디지털 교육의 나아갈 방향을 잡는 것이 필요하다. 이에 본 연구는 LG 유럽 디자인 센터를 기반으로 디지털 교육의 선진국인 영국과, 복지 사회의 기반위에서 적극적인 디지털 교육을 이끌고 있는 스웨덴을 사례 연구 대상국으로 선정하며. FGI, 집중 관찰 분석, 설문, 휴리스틱, KJ 법을 통해 2차례로 분석하며, 현황분석은 국가적으로 막대한 투자를 받고 있는 영국을 중심으로 살펴보며, 스웨덴은 사례연구 및 설문 분석 시 포함한다. 분석 결과 대체적으로 디지털 교과서를 단독으로 사용하는 교육보다는 프린트 교과서 사용을 병행하여 각 매체의 장단점을 적절히 활용하여 수업하는 것을 선호하고 있었으며 학생 및 교사의 만족도도 높게 나타났다. 특히 교사들이 쉽게 적응할 수 있는 디지털 매체의 GUI 디자인이 요구되고 있었다. 이에 향후 디지털 교과서 디자인 기획에 있어서 타겟층(교사와 학생)의 사전 조사 및 설문 분석을 통해 사용자의 특성을 고려한 디지털교육 매체만을 위한 디자인 기획을 해야 한다. 본 연구결과는 디지털 해외 선진국의 사례를 파악하여 국내 디지털 교육산업에 기초 자료로 활용하는데 의의가 있다.

Developments in the understanding of fire behaviour for large open-plan spaces typical of tall buildings have been greatly outpaced by the rate at which these buildings are being constructed and their characteristics changed. Numerous high-profile fire-induced failures have highlighted the inadequacy of existing tools and standards for fire engineering when applied to highly-optimised modern tall buildings. With the continued increase in height and complexity of tall buildings, the risk to the occupants from fire-induced structural collapse increases, thus understanding the performance of complex structural systems under fire exposure is imperative. Therefore, an accurate representation of the design fire for open-plan compartments is required for the purposes of design. This will allow for knowledge-driven, quantifiable factors of safety to be used in the design of highly optimised modern tall buildings. In this paper, we review the state-of-the-art experimental research on large open-plan compartment fires from the past three decades. We have assimilated results collected from 37 large-scale compartment fire experiments of the open-plan type conducted from 1993 to 2019, covering a range of compartment and fuel characteristics. Spatial and temporal distributions of the heat fluxes imposed on compartment ceilings are estimated from the data. The complexity of the compartment fire dynamics is highlighted by the large differences in the data collected, which currently complicates the development of engineering tools based on physical models. Despite the large variability, this analysis shows that the orders of magnitude of the thermal exposure are defined by the ratio of flame spread and burnout front velocities (V_S / V_BO), which enables the grouping of open-plan compartment fires into three distinct modes of fire spread. Each mode is found to exhibit a characteristic order of magnitude and temporal distribution of thermal exposure. The results show that the magnitude of the thermal exposure for each mode are not consistent with existing performance-based design models, nevertheless, our analysis offers a new pathway for defining thermal exposure from realistic fire scenarios in large open-plan compartments.

Through the experimental narrative construction by authorial divinity, Muriel Spark's novels and films based on her fiction show the difficulty of living like a human being under various inhumane and manipulative circumstances of the modern capitalistic society. By adopting flash-forward, self-reflection, and deceptive omnipotent viewpoints, her work has surprisingly predicted the post-modern trend in which humans are increasingly attracted and interpellated to the digitalized media. Muriel Spark called the recent anesthetic situation by stimulation "a driver's seat" because it is a symbol of how humans should act to maintain the critical subject. Emphasizing the value of self-reflection, religion and morality in the mechanized society, Muriel Spark stressed literature should play the role of helmsman who sails safely in the rough sea. In Muriel Spark's works, God is often synonymous with writers. As a Jewish immigrant she experienced alienation in Scotland, marital violence, prejudices of the London-based publishing world, Nazism, and Watergate. For her, the harsh reality of the modern society needs to be guided and complemented by something beyond human control. But rather than relying entirely on traditional Catholic doctrines such as Graham Greene and Evelyn Waugh, Muriel Spark has taken a personal, religious view of literature and insists that the genuine writer must play God's play. Seeking for the speculative vision for the future of human life in God's plan, she tries to understand the complex twisted motives of human beings which are often far from the ideal form. Simply put, her search of self-reflection, religion and ethics is modeled on the God's plan for the ideal human being who is supposed as the writer with the transfigurative imagination of the trinity.
