The objective of this study is to evaluate the interior elements supporting the safety, mobility and accessibility for the visually impaired persons in the public, government, and other facilities. Ten facilities were analyzed with a checklist based on the architectural codes and the users needs. Also theses facilities were reviewed with mandatory items of the Ministry of Health and Welfare. It appeared that the arrangement of elements such as stair, elevator and restroom, the plan of circulation path and the signage of way-finding had more problems than the details of each element. In addition, institutional facilities for the blinds and trainstation provided easy accessibility, adaptability and mobility compared to the hospital and bus terminal. Suggestions were provided to solve the problem which were found.

Rapid Prototyping (RP) techniques have their unique characteristics according to the working principles: stair-stepped surface of parts due to layer-by-layer stacking, low build speed caused by line-by-line solidification to build one layer, and additional post processing to improve surface roughness, so it is required very high cost to introduce and to maintain RP apparatus. The objective of this study is to develop and design a new RP process, Variable Lamination Manufacturing using expandable polystyrene foam sheet as part material (VLM-S), which can make up for the disadvantage of existing techniques, and to develop an apparatus to implement the process. In order to examine the possibility of practical utilization of the proposed VLM-S process for prototyping of a general three-dimensional shape, an auto-shift lever knob and a pyramid shape were fabricated.

An effective design of a public space that properly functions as a resting place in city can be found through the community facility studies. This study, based on the ecological psychology, discusses the mutual relationships between human behaviors and physical and social environment. It is demonstrated that design elements, such as chairs, tables, stairs, a flower bed, a stair-shaped exterior wall, a pond and others play important roles in providing environment for different human behaviors in public space. These environmental design elements also increase a variety of behavior for users.

As the seniors and the disabled has increased, the demand for cultural centers has also increased in many local areas. This means that the local cultural centers designed from the viewpoint of universal design are needed, so that to be used by everyone without any difficulties. This study examined the applicability of universal design principles to the public service areas of the local cultural centers. The subject cultural centers were three local ones which had seating capacity of more than 1,000 and opened after the year of 2,000 in Gyungnam. The spatial scopes of the study were six public service areas of the local cultural centers : entrance area, corridor and pathway, stair, ramp, elevator, and rest room. The total 65 items for evaluating the applicability of universal design were selected and examined for six areas. On the whole, accessibility, such as wide pathway and flat floor was good. However, the following improvements were needed. 1) Handrails and rounded corner were needed on walls. 2) Consideration of the visually impaired like as braille sign was needed. 3) The handrails on ramp should be installed for usability. 4) The automatic door would be more useful to the physically disabled users. 5) Wider space and familiar handrail design and color were needed in the rest rooms for the handicapped.

Before incorporating the earthquake-resistance design in design code(998), most of existing residential buildings were built without having lateral resistance capacity in addition to their structural peculiarity such as exterior stair ways, exterior elevator room. For these reasons, the retrofitting research demands for existing buildings arise recently and many retrofitting methods are proposed. These tasks are important to reduce the enormous economic loss and environmental issues. In this study, Scaled residential buildings with/without lateral resistance were tested and monitored with external lateral load especially toward the longer side of the building. From these experiments, enhanced retrofitting methods of old shear wall system are proposed and also compared with structural analysis.

This study was carried out to understand the characteristics of stairs in Palladio's villa. The subject of study are selected the twenty two villas with drawing in his book ‘The four books of Architecture’. Their cases are represented the characteristics of stair in architectural composition. Accordingly, it was analyzed and classified the architectural characteristics into space, form and plan at a villa. In conclusion, in aspect of spacial plan, staircases of Palladio's villa was presented more open and light in comparison with darked space of the medieval age. And it was intended to the connection or division between spaces of different character In an aspect of formal plan, dynamic form of stairs was divided into the two types. First, it was represented the effect of articulation in form. Second, stairs were represented the diagonal with the shape of itself. In an aspect of plan, his idea is coexisted with traditional thought and rational idea through the arrangement of symmetry md asymmetry. But at any rate, his concern was sought for the reasonable position. Also, he had represented the various characteristics in stairs such as his works in Renaissance period.

This paper described a novel locomotion interface that can generate infinite floor for various surface, named as virtual walking machine. This interface allows users to participate in a life-like walking experience in virtual environments, which include various terrains such as plains, slopes and stair ground surfaces. The interface is composed of two three-DOF (X, Y, Yaw) planar devices and two four-DOF (Pitch, Roll, Z, and relative rotation) footpads. The planar devices are driven by AC servomotors for generating fast motions, while the footpad devices are driven by pneumatic actuators for continuous support of human weight. To simulate natural human walking, the locomotion interface design specification are acquired based on gait analysis and each mechanism is optimally designed and manufactured to satisfy the given requirements. The designed locomotion interface allows natural walking(step: 0.8m, height: 20cm, load capability: 100kg, slope:30deg) for various terrains.

The purpose of this study is to suggest the materials for developing the new house style by analysing the space characteristics of wood frame houses in suburbs of Seoul. For this, we analysed 45 drawings(site plan, floor plan, elevation, section) that were designed by MICHOO, WOOD-LAND, STUGA and CHOWONJUTECK company etc. The space design characteristics that we found are as follows; 1. The wood is fragile to humidity. Therefore this characteristic is especially considered in designing the space of bathroom and utility room. 2. It is the merit of wood frame house that inner space can be designed variously by using spilt-level and the slope of roof. 3.The public space and private space are completely separated in most cases and the stair is located in the middle of house. This structure of house is short of horizontal openness. Instead, most houses gets vertical openness by making second floor on the living room opev. 4. In wood frame house as the rural house, the outer space is well used by setting up deck and balcony. The outer spaces like deck and balcony are usually used as a part of life space in connected with living room, dining room, master bed room and family room. 5. The public spaces like kitchen, living room, dining room and family room are considered so important in design that those are arranged in front in order to have good outlook and directiov.

Recently, Productivity of the construction industry has been decreasing than other industries. Because of this, BIM is being spread in the construction industry. However, quality criteria for BIM data is insufficient. Regulation information is an important factor for initial architectural design evaluations. However, building code and related regulation are numerous. National building code structure in Korea is much more complex than other countries. The purpose of this study is to suggest the typology method of building code and apply to real regulations. To achieve this purpose, the authors have extracted required information to from original regulation for code checking and suggested mapping methods between extracted information and information of IFC scheme. In addition, the authors have represented EXPRESS-G diagram for extracting information from IFC scheme and suggested code checking method through stair case. Output of this study can be used as a base line data for automated code checking system based on open BIM. Automated code checking system will be utilized in architectural design evaluations and supported to increase design quality. It can be used to mount in SEUMTER that is the construction administration system of Ministry of Land, Infrastructure and Transport (MOLIT).
