Purpose: Recently, Universal design has been applied to a variety of concepts of social integration in the national legislation and institutions, however, the applying to urban railway station is not satisfied. Most of cases, the handicapped can not work continuously, universal design must be provided. Methods: This study derives the detailed criteria through comparing and analyzing an national and international universal design-related system in transit zone. And the status is investigated in transit zone of domestic urban railway station. Improved national standard requirements are derived considering the type of the handicapped and universal design principles. Result: The domestic status shows that the most lacking entry criteria is not specified in national standards or the design is a lowest-level required by criteria through comparing detailed criteria drawn into domestic analysis. Therefore, in order to provide a pedestrian environment to meet the universal design principles and requirements for the handicapped, there is a need to re-establish with a specific national standards. Implications: This study will draw on universal design standards for seamless transfer in transit zone of urban railway station. The next studies are needed to target the overall paths ranging from outside to landing in urban railway station.

The purpose of this study is to evaluate preferences for spatial composition by urban design guidelines of detached housing areas using CG simulation, with the aim of contributing to the improvement and management of residential townscapes. The list of urban design guidelines for detached housing areas was derived from an analysis of urban design guidelines and landscape regulations from the U.S.A, Japan, and Korea. These guidelines comprise building guidelines, landscape guidelines, street guidelines, and sign guidelines. Through the preferences revealed by CG simulation, an optimum presentation method for the urban design guidelines was determined. Based on the results of preferences, an appropriate management system and regulation standards were proposed. In conclusion, the efforts carried out on the study and legislation of a management system and regulation standards for the urban design guideline will accomplish the amenity of residential environments.

Urban parks and open spaces provide the community residents with the most easily accessible source for outdoor recreation, contributing also to the improvement of quality of natural environment in urban area. The demands of urban residents' for more and better green area are ever-increasing. However, the level of most urban open spaces which are easily accessible for residents are not satisfactory to meet the residents' demand in availability and in quality as well. Most existing urban open spaces are simply built of green areas only or have been developed in almost identical design with little consideration for individual uniqueness of the site. When developing neighbourhood parks in urban housing complexes, for example, little consideration is being given to topographical conditions, interrelation with the adjacent green area, or viability of the urban ecosystem. In many cases, urban park development projects are being done with serious negligence of natural properties of the site, by even destroying existing healthy woodlands. for instance. The objectives of this study are; -To survey on the domestic and the overseas cases of regulatory systems, development status and planning methods for urban open space. -To identify underlying issues of residental park developments in urban housing projects and establish appropriate improvement measures thereof, by studing and analyzing current-use data of developed urban parks and management status thereof. -To establish improved standards for urban open space planning, by integrating above surveys and studies, and recommendation for revision of related legislation is also presented to implement these standards.

In general, design of urban intersections are fundamentally different from rural intersections, but current urban intersection design has been appled to rural standards. This study has suggested the design standard for urban intersection grades based on the existing literature, field investigating and comparative analysis. Moreover, this study analyzes and compares the differences between urban and rural intersections, and intersections have been derived by appropriate design standards after reviewing the domestic and international grades design criteria. Site survey was performed to validate the derived design criteria by analyzing statistically to establish the design standards. Results were produced for the intersection portion grade standards by comparing the number of instructions which produced appropriate slope degree from 2.5% to 3% in normal condition and slope can be extended to 5% in some critical cases. In-situ investigation was performed to validate the produced data where slope was found from 0.0~8.6%. Additional data of accident analysis were also collected for the validation of the suggested data and correlation analysis was performed using the SPSS tool. Data were analyzed statistically using 95% significance level for vehicle-to-vehicle collided, head-on collision accident rates, where accident rates significantly correlated with the grade. Therefore, appropriate grade at the intersection should be designed and applied in order to reduce the number of accidents at the intersection. Finally, appropriate grades for urban intersections are suggested from 1-3% for normal cases and grades could extend up to 5% for unavoidable cases where extra care must be taken when designing.

The purpose of this review paper is to briefly describe main the features of novel procedures developed by the National of Standards and Technology (NIST) for the design of tall buildings. Topics considered in the paper include: the division of tasks between wind and structural engineers; the determination of wind effects with specified mean recurrence intervals by accounting for wind directionality; the risk-consistent design of structures subjected to multiple wind hazards; iterative dynamic analyses and member sizing, including the use of modern optimization approaches; and commonalities of and differences between Database-assisted Design (DAD) and Equivalent Static Wind Loads procedures. An example of the application of the DAD procedure is presented for a reinforced concrete structure. Also included in the paper is an introduction to ongoing research on the estimation of wind load factors or of augmented design mean recurrence intervals commensurate with the uncertainties in the factors that determine the wind effects.

From the viewpoint of the importance of the division theory based on topography(pyungsu) derived from the uniqueness in topography, not to mention of the function of ridge in ruban areas, the destroy of ridges should be prevented from the development of hill areas. This study intends to propose the basic concepts and principles to protect the ridge axis with green in open space and landscape planning. The main results are summarized as follows : First, eco-bridge across the ridges will be connected for the purpose of ecosystem restoration. Second, the protection and restoration of green ridge axis can be completed by Green Structure Plan which has principles and standards such as. - layout of development axis and establishment of rules on preservation - the practical use of various preservation methods and the standards suitable to the methods - laying down the standards of restoration according to the height from ground level - the application of zoning such as height district and urban design for preservation Finally, the design of implementation tools must be needed for protection and restoration.

Current MEP designs are mostly applied by 2D-based design methods and tend to focus on simple modeling or geometry information expression such as converting 2D-written drawings into 3D modeling without taking advantage of the strength of BIM application. To increase the demand for BIM-based MEP design, geometric information, and property information of each member of the 3D model must be conveniently linked from the phase of the Design Development (DD) to the phase of Construction Document (CD). To conveniently implement a detailed model at each phase, the detailed level of each member of the 3D model must be specific, and an automatic generation of objects at each phase and automatic detailing module for each LOD are required. However, South Korea's guidelines have comprehensive standards for the degree of MEP modeling details for each design phase, and the application of each design phase is ambiguous. Furthermore, in practice, detailed levels of each phase are input manually. Therefore, this paper summarized the detailed standards of MEP modeling for each design phase through interviews with MEP design companies and related literature research. In addition, items that enable auto-detailing with DYNAMO were selected using the checklist for each design phase, and the types of detailed methods were presented. Auto-detailing items considering the detailed level of each phase were classified by members. If a DYNAMO algorithm is produced that automates selected auto-detailing items in this paper, the time and costs required for modeling construction will be reduced, and the demand for MEP design will increase.

This study proposes the logical data model design of a spatial data model that complies with international standards for the waterworks of underground facilities. We conduct a preliminary study related to underground spatial data standards and data models, and review the status of the existing systems. Then, we defined the conceptual design direction of underground spatial data model based on the problems and issues. Next, we defined the terminology, classification, semantic relationships of waterworks. Next, for the conceptual design of the underground spatial data model, we defined the naming criteria for all data according to the waterworks classification. In addition, a logical model is drawn and described using UML (Unified Modeling Language) diagrams. Based on the results, it is expected that the accuracy related to underground facilities data will be improved.
