  • The purpose of this study is to find the characteristics of design council criteria of metropolitan cities in Koreas. For comparative analysis, four main concepts are used ; 1) self-administering vs discretionary 2) prescriptive vs performance 3) conformity vs contrast 4) point system of criteria. The results of this study were as follows; 1) there were three types of cirteria; strong discretionary (DG), discretionary oriented (BS, US) and combination type (SL, DJ, ICN, GJ) 2) structural properties of forms are controlled by prescriptive criteria, and layout or design elements by performance criteria 3) visual openness and diversity are main items of most metropolitan cities 4) street-faced design was neglected but tended to focus on the self-contained layout 5) visual density indexes were diversified from elevation blockage degree. For further advanced research, it is necessary to investigate the actual effects and differences of regulative types - prescriptive vs performance, and of each design criteria, especially prescriptive ones in improving the design quality.

  • PURPOSES : In this study, design elements of rest areas for drowsy drivers are classified and appropriate criteria for each design element are presented. METHODS : By comparing and analyzing the design criteria for rest areas, the most appropriate installation criteria were suggested by considering the driving patterns of rest area users. RESULTS : As a result of the study, elements influencing the design of rest areas for drowsy drivers are suggested such as installation location and installation type. In addition, proper separation distance between resting areas was suggested considering vehicle flow, users' fatigue and physiological needs. Other criteria for rest areas were also suggested. CONCLUSIONS : Proper safety facilities were not installed in rest areas because appropriate criteria were not established. In this study, design elements were derived and installation criteria were designed so that rest areas could be used safely and conveniently.

  • This paper presents an integrated wind-induced dynamic analysis and computer-based design optimization technique for minimizing the structural cost of general tall buildings subject to static and dynamic serviceability design criteria. Once the wind-induced dynamic response of a tall building structure is accurately determined and the optimal serviceability design problem is explicitly formulated, a rigorously derived Optimality Criteria (OC) method is to be developed to achieve the optimal distribution of element stiffness of the structural system satisfying the wind-induced drift and acceleration design constraints. The effectiveness and practicality of the optimal design technique are illustrated by a full-scale 60-story building with complex 3D mode shapes. Both peak resultant acceleration criteria and frequency dependent modal acceleration criteria are considered and their influences on the optimization results are highlighted. Results have shown that the use of various acceleration criteria has different implications in the habitability evaluations and subsequently different optimal design solutions. The computer based optimization technique provides a powerful tool for the lateral drift and occupant comfort design of tall building structures.

  • Since 1970s, energy-saving design criteria of buildings has been improved through numerous revisions. The purpose of this research is to show how energy saving design criteria affects heating energy consumption of apartments using district heating. Heating energy consumption has been measured in 4 apartments located in Gyeonggi province, Korea from Nov. 1,2007 through Oct. 31, 2008. Collected data was regressed to linear correlations. Heating energy consumptions were calculated for past, present and future energy-saving design criteria, which are outdoor temperature, ventilation and insulation. The results show that present design criteria has reduced heating energy consumption by 15%, and the future criteria will reduce the energy consumption by 42% compared to the criteria before 2001.

  • Inclusive design is increasingly gaining attention, as some people find using products difficult after becoming physically impaired, despite daily use. However, making inclusive products is a challenge for designers or companies, as a lack of knowledge and tools stems their low involvement in it. Developing inclusive design tools is thus needed. This study developed criteria to assess upper extremity capabilities corresponding to specific daily activities. A questionnaire survey was conducted among 58 physiatrists and orthopedists. Non-parametric statistics were employed and medians were adopted as representative scores in the assessment criteria based on normality and reliability test results, non-normal data, and strong reliability of respondents in ranking. Consequently, an assessment tool was developed with 14 criteria (divided into range of motion and strength) and capability scores between 0 and 100, which discerned the moderately impaired from the severely disabled and fully capable. Since the doctors agreed to adopt the criteria but assign numeric values, especially for mild impairments, their capability assessment perception was likely influenced by dichotomy. To compensate for these deficits, qualitative or ergonomic approaches are considered simultaneously.

  • We consider the experimental design problem of selecting values of design variables x for observation of a response y that depends on x and on model parameters $\theta$. The form of the dependence may be quite general, including all linear and nonlinear modeling situations. The goal of the design selection is to efficiently estimate functions of $\theta$. Three new criteria for selecting design points x are presented. The criteria generalized the usual Bayesian optimal design criteria to situations n which the prior distribution for $\theta$ amy be uncertain. We assume that there are several possible prior distributions,. The new criteria are applied to the nonlinear problem of designing to estimate the turning point of a quadratic equation. We give both analytic and computational results illustrating the robustness of the optimal designs based on the new criteria.
