  • This study developed an evaluation system to explore the effect of the environmental temperature on the stress redistribution produced by cable stress relaxation of structural members in a steel cable-stayed bridge. The generalized Maxwell model is used to estimate stress relaxation at different temperatures. The environmental temperature is represented using the thermal coefficients and temperature loads. The fmincon optimization function is used to determine the set of stress relaxation parameters at different temperatures for all cables. The ABAQUS software is employed to investigate the stress redistribution of the steel cable-stayed bridge caused by the cable stress relaxation and the environmental temperature. All of these steps are set up as an evaluation system to save time and ensure the accuracy of the study results. The developed evaluation system is then employed to investigate the effect of environmental temperature and cable type on stress redistribution. These studies' findings show that as environmental temperatures increased up to 40 ℃, the redistribution rate increased by up to 34.9% in some girders. The results also show that the cable type with low relaxation rates should be used in high environmental temperature areas to minimize the effect of cable stress relaxation.

  • Purpose: As we are facing the global crisis from the climate change and energy depletion, urgent actions are needed to design a integrated sustainable building. This paper suggests that a sustainable design awards can stimulate for architects to bring the cutting-edge ideas into a realized building in comparison to green building certification system. AIA COTE Top 10 design awards, organized and run by AIA(American Institute of Architects) COTE(Committee on the Environment) from 1997, is analyzed as a case study. By researching the core of the AIA COTE Top 10 design awards system in terms of evaluation measures and submission requirements, meaningful suggestions were drawn to supplement Korea Green Building Awards system and to design and realize leading green buildings in Korea. Method: The comparison between AIA COTE Top 10 and Korea Green Building Design Awards was made in terms of evaluation measures, submission requirements, and green building certification systems. Result: This paper finally suggests the following three points in conclusion: 1) Set the standards of evaluation measures reflecting the three aspects(economy, environment, social) of sustainability, 2) Set the qualitative evaluation measures and corresponding submission requirements that can apply in the design awards in comparison to green building certification system, 3) Develop and balance submission requirements in response to evaluation measures to proceed systematic evaluation of the green buildings.

  • This study aimed to develop a fitted torso pattern with an improved fit for inverted-triangular males in their twenties. For this study, six torso patterns were collected, compared and evaluated, and a fitted torso pattern was developed using virtual fittings. The research results are as follows. First, the fitted torso pattern received a good rating as a result of the virtual fitting evaluation: waist dart set 2 of the front; the amount of comfort is set at 5 cm around the chest, 4 cm around the waist and 10 cm around the hips. Second, the evaluation of virtual fitting of the development pattern showed that fit evaluation was 4.11/5 points, ease evaluation was 6.53/7 points, and that the stress map and airgap were suitable for the human body. Third, the actual fit evaluation of the development pattern was 4.25/5 points, 6.35/7 points for ease evaluation, and 4.81/5 points for motion evaluation. Fourth, there was no significant difference between the results of the virtual and actual fitting evaluation with the objectivity test. It is therefore possible to apply a pattern developed through a virtual fitting to an actual human body and to confirm the objectivity of the pattern.

  • [감성지향 제품] 디자인에 있어서는 디자이너가 제품을 통해 표현하려는 이미지와 사용자가 제품을 통해 느끼는 감성적 평가와의 사이에 존재하는 갭(gap)이 문제가 되고 있는데, 이 갭을 해소하는 데에 있어 디자인 과정에서 활용되어진 이미지화상들과 디자인 평가를 위해 사용되었던 감성적 평가어 사이와의 관련도에 관한 정보는 특히 유효하다. 본 연구에서는 이러한 관련도 정보에 근거하여, 이미지 화상 및 이미지어 탐색을 통해 스타일링 디자인을 지원하는 감성검색시스템을 제안한다. 본 시스템에 있어서 관련도 정보는 이미지어와의 유사도를 유의어 계수로 상정한 퍼지 시소러스에 의해 표현된다. 또한 이미지어 사이의 유사도는 이미지 화상 평가를 기초로 산출된다. 이미지 탐색은 검색 중시도(weight)를 파라메터로한 퍼지 시소러스 전개의 알고리즘에 의해 실행되며, 탐색 모드로서 이미지어 상호간, 이미지어에서 이미지화상, 이미지 화상에서 이미지어, 이미지 화상간의 합계 네 종류의 모드가 제공 된다. 또한 이들 모드간의 이행은 직접 조작형 인터페이스에 의해 실행되며, 이로 인해 아이디어 탐색단계에 있어서의 디자이너의 발상과정이 원활하게 지원된다. 시스템은 감성적 평가의 계측 유니트와 갭의 연산, 가시화 유니트로부터 구성되며, 조작의 일관성을 유지하기 위해 통일적인 인터페이스의 환경 하에서 구축하였다.

  • Developing a modern Han-style design and providing support for the commercialization development model in recent years has been propelled by the Han-style Support Strategies of the central government in conjunction with Han-style revitalization related projects that reflect the efforts of local governments. Han-style revitalization, the rekindling and revaluing of human behavior and interest in local governments following the social and cultural changes of the past decades, has emerged as an increasingly traditional area of concern in Han-style design. The purpose of the study was to provide a method which clarifies the design rules of the Han-style bathroom based on an evaluation of sensibilities and a rough set theory, and to give the components meaning and to systematize the method. Essentially, the Han-style bathroom design evaluation is a complex multi-criteria decision making process that seeks to improve the effectiveness and objectively of the Han-style bathroom design. Han-style bathroom design can be displayed in a graphical representation in response to input from the evaluation concerning sensibilities. Because the graphical representation is composed of 3D data, it is possible to display the Han-style bathroom design form in any desired perspective and also to perform shading and other operations. With the proposed method, it is possible to obtain a combination of several contributory components which can be referred to as Reducts, Covering Index and Column Score. Han-Style/Non Han-Style Bathroom Designs were identified by the combination of several components.

  • Objective: The aim of this study was to investigate the correlation between 3D visual fatigue and physiological measures by canonical correlation analysis enabling to categorical correlation. Background: Few studies have been conducted to investigate the physiological mechanism underlying the visual fatigue caused by processing 3D information which may make the cognitive mechanism overloaded. However, even the previous studies lack validation in terms of the correlation between physiological variables and the visual fatigue. Method: 9 Female and 6 male subjects with a mean age of $22.53{\pm}2.55$ voluntarily participated in this experiment. All participants were asked to report how they felt about their health sate at after viewing 3D. In addition, Low & Hybrid measurement test(Event Related Potential, Steady-state Visual Evoked Potential) and for evaluating cognitive fatigue before and after viewing 3D were performed. The physiological signal were measured with subjective fatigue evaluation before and after in watching the 3D content. For this study suggesting categorical correlation, all measures were categorized into three sets such as included Visual Fatigue set(response time, subjective evaluation), Autonomic Nervous System set(PPG frequency, PPG amplitude, HF/LF ratio), Central Nervous System set(ERP amplitude P4, O1, O2, ERP latency P4, O1, O2, SSVEP S/N ratio P4, O1, O2). Then the correlation of three variables sets, canonical correlation analysis was conducted. Results: The results showed a significant correlation between visual fatigue and physiological measures. However, different variables of visual fatigue were highly correlated to respective HF/LF ratio and to ERP latency(O2). Conclusion: Response time was highly correlated to ERP latency(O2) while the subjective evaluation was to HF/LF ratio. Application: This study may provide the most significant variables for the quantitative evaluation of visual fatigue using HF/LF ratio and ERP latency based human performance and subjective fatigue.

  • Landscape zones have been designated as aesthetic old town districts across a wide range of Nakakyo-Ku and Shimokyo-Ku, city center of Kyoto, Japan. In these districts in which traditional structures and new buildings coexist, regulations of restriction on acts such as new building's heights, shapes, materials, and colors are carried out according to local governmental landscape ordinance based on Scenic Conservation Act. And yet, minimal fulfillment of the regulations according to different designer's subjective interpretation and principle of economy is rather creating abnormal shapes not harmonized with the traditional landscape. Thus, this study aims to extract combinations between form elements of middle and high rise apartment facade that affects 'harmony' and 'mismatch' in the districts by clarifying the social rules commonly implied based on intuitive judgments (sensibility evaluation) in which human experiential knowledge is involved. As research methods, the study first analyzes the form elements of the facade through a field survey, sets up a standard model through tasks of classification and segmentation and draws computer graphic images with 99 different patterns based on it. Based on these images, this study carries out sensibility evaluation and analyzes experimental data applying the rough set theory. As a result of the analysis, the combinations of form elements that affect harmony or mismatch act greatly when the colors and shapes of the pillars, positions and the patterns of the use of the first floor are combined.
