Fire safety engineering is a critical specialization to include in the design of a tall building yet is often excluded from the Building Information Model (BIM) and integrated design process. The design of fire safety systems is interdependent with building/structural geometry, HVAC, mechanical, and electrical systems. A BIM is a 3D visual representation that stores data on these kinds of systems. The compatibility between BIM and fire safety design seems obvious yet has received a dearth of attention in structural (fire) engineering literature. The authors herein have reviewed over 40 recent papers on utilizing BIM for fire safety engineering, focusing on contemporary literature to obtain a more up-to-date review of the state-of-the-art. The resulting trends, technologies, research gaps, and methodologies are presented in this paper. Adoption of BIM in fire safety engineering is slow and behind other disciplines which may be improved if research involved more industry partners. For BIM technology to reach its potential, industry manufacturers need to provide high LOD fire BIM objects, fire engineers and researchers need to collaborate on future advancements, and building owners/management need to be educated on how to use the benefits provided.

Parametric design systems serve as powerful assistive tools in the design process by providing a flexible approach for the generation of a vast number of design alternatives. However, contemporary parametric design systems focus primarily on low-level engineering and structural forms, without an explicit means to also take into account high-level, cognitively motivated people-centred design goals. We present a precedent-based parametric design method that integrates people-centred design "precedents" rooted in empirical evidence directly within state of the art parametric design systems. As a use-case, we illustrate the general method in the context of an empirical study focusing on the multi-modal analysis of wayfinding behaviour in two large-scale healthcare environments. With this use-case, we demonstrate the manner in which: (1). a range of empirically established design precedents -e.g., pertaining to visibility and navigation- may be articulated as design constraints to be embedded directly within state of the art parametric design tools (e.g., Grasshopper); and (2). embedded design precedents lead to the (parametric) generation of a number of morphologies that satisfy people-centred design criteria (in this case, pertaining to wayfinding). Our research presents an exemplar for the integration of cognitively motivated design goals with parametric design-space exploration methods. We posit that this opens-up a range of technological challenges for the engineering and development of next-generation computer aided architecture design systems.

In literature, a description of costume represents an individual's characteristics when the object is an individual. If the literary object is a certain group in a certain region, it would play an important role in representing the culture of time. It clearly shows that aesthetic consciousness of Hyo-Suk Lee who had accepted the western dandyism was well expressed in his literary works. Hyo-Suk has been unique in describing life-styles such as beauty of costume, art-for-art's sake, and leisure activities, and color imagery in his works. The color and the style of the costume show us the mental state of the wearer. They also affect the emotional states of other people. Hyo-Suk's "Pollen(화분)" and "Byukongmuhan(벽공무한)" confirm the fact that the mentality of the people can be hinted through the description of costume. They also ascertain that the color imagery retained by a special color can be altered by different circumstances and settings. Hyo-Suk applies in his works the effect of vivid color contrast, which newly appeared in Fauvism, to the description of costume. In consequence, he reflects the color aesthetics of Modern Art in which the fine art has an effect on the applied art.

지폐는 물물교환, 가치척도의 도구일 뿐만 아니라 한 국가의 정체성을 나타내는 문화적 상징 기호라 할 수 있다. 본 연구의 목적은 세계 선진국과 우리나라 지폐를 대상으로 디자인 특성을 분석하고, 문화코드로서 각국의 지폐 디자인에 나타난 국가 이미지 특성을 비교 분석하고자 한다. 연구결과 첫째, 지폐 디자인의 사용성 측면을 권종 수, 크기유형, 색상, 점자체계의 항목으로 평가하였으며, 스위스의 지폐와 유로화가 상대적으로 우수한 것으로 평가되었다. 둘째, 지폐 디자인에 표현된 이미지 유형은 우리나라를 비롯한 미국, 일본 등의 국가는 국가 체제 구축에 공헌한 인물을 주요 소재로 등장시켜 '국가주도형' 문화를 나타낸다. 반면에 유럽 국가는 예술가와 과학자, 그리고 여성 인물 등을 주요 소재로 선정하여 남녀평등의식이 반영, '시민문화 주도형'임을 알 수 있다. 셋째, 스위스, 네덜란드, 프랑스, 영국 등의 지폐는 작품형 소재를 사용하고, 화려한 색채, 컴퓨터그래픽 표현기법, 개성적인 구성 등으로 지폐 디자인을 하나의 시각 예술작품으로 표현하고 있다. 본 연구는 세계적 맥락에서 우리나라 지폐디자인의 현주소를 진단해보고자 하였으며 이로써 새로운 지폐 디자인 연구를 위한 자료로 활용될 수 있기를 기대한다. 또한, 문화 디자인의 관점에서 각 나라의 국가 이미지를 상징하는 주요 매체로서 지폐 디자인의 중요성을 다시 한번 인식시키고자 하는데 의의를 갖는다.

Over the last three decades, Performance-based Earthquake Engineering (PBEE) has been mainly developed for high seismicity regions. Although information is abundant for PBEE throughout the world, the application of PBEE to lower-seismicity regions, such as those where the magnitude of the maximum considered earthquake (MCE) is less than 6.5, is not always straightforward because some portions of PBEE may not be appropriate for such regions due to geological differences between high- and low-seismicity regions. This paper presents a brief review of state-of-art PBEE methodologies and introduces the seismic hazard of lower-seismicity regions, including those of the Korean Peninsula, with their unique characteristics. With this seismic hazard, representative low-rise RC MRF structures and high-rise RC wall residential structures are evaluated using PBEE. Also, the range of the forces and deformations of the representative building structures under the design earthquake (DE) and the MCE of South Korea are presented. These reviews are used to propose some ideas to improve the practice of state-of-art PBEE in lower-seismicity regions.

This paper explains about general considerations and project management for a State of the Art utility supervisory systems. [1] The implementation and management of a supervisory system design project requires both a dedication of resources and application of good communications in order to be suc-cessful. [2] Success is on time delivery of a system to a satisfied customer at the proposal cost, [3] The recent experience of a company plus the collected comments from a number of ex-perienced control center project management provide a guideline for the company who is considering such a project. The Comments reflect typical situations or decision points faced by the project Manage.[2] This paper also attempts to help engineers in the task of specifying buying, and instal-ling a supervisory system[1]

This paper provides a state-of-the-art review on advanced analysis models for investigating the load-displacement and ultimate load behaviour of steel and composite frames subjected to static gravity and lateral loads. Various inelastic analysis models for steel and composite members are reviewed. Composite beams under positive and negative moments are analysed using a moment-curvature relationship which captures the effects of concrete cracking and steel yielding along the members length. Beam-to-column connections are modeled using rotational spring. Building core walls are modeled using thin-walled element. Finally, the nonlinear behaviour of a complete multi-storey building frame consisting of a centre core-wall and the perimeter frames for lateral-load resistance is investigated. The performance of the total building system is evaluated in term of its serviceability and ultimate limit states.

Seismic probabilistic risk assessment(RA) rather than deterministic assessment provides more valuable information and insight for resolving seismic safety issues in nuclear power plant design. In the course of seismic PRA seismic fragility analysis is the most significant and essential phase especially for structural or mechanical engineers. Lately the seismic fragility analysis is taken as a useful tool in general structural engineering as well. A systemized and synthesized procedure or technology related to seismic fragility analysis of critical industrial facilities reflecting the unique experiences and database in Korea is urgently required. This paper gives a state-of-the-art reviews of PRA and briefly summarizes the technologies related to PRA and seismic fragility analysis before developing an unique technology considering characteristics of Korean database. Some key items to be resolved theoretically or technically are extracted and presented for the future research.
