Generally, rural housing in Korea have had target of people who are in good physical health rather than the disabled. Therefore, it is difficult to offer high quality residential environment for the elderly and the disabled. The purpose of this study is to present the remodeling of rural house for the disabled. this study divides the a rural house into 7 sectors : a passage to entrance, an entrance hall, a livingroom, a bedroom, a bathroom, a kitchen, and etc. this study propose the following renovation plan that rural housing to be barrier free space. First, in passage to entrance of the house, people with disabilities should not experience difficulties in walking, so installing ramps to remove the stepped slope grade without slip so that the floor finish should be. Second, install grab handle on the wall inside the housing so that the disabled can lean on the handle. Third, placing the furniture in the bedroom that wheelchair can be rotated, and make to lower the height of the switchs. Forth, install a non-slip floor tile to prevent accidents in the bathroom.

Residents of apartment complex make various attempts for their community. However, a community space in current apartment complex is planned uniformly without consideration of residents' diversity and the physical aid environment for aged people, children and the handicapped is in limited supply. Community spaces in apartment complexes satisfy various residents but need further study about this. The purpose of this study intends to evaluate the applicability of Universal design of community in apartment complex. Research was done examining 12 different apartment complexes in Seoul, which were all built after the year 2002. Researched community spaces were the senior citizen's center an indoor exercise area and a preschool which were evaluated and measured by passage areas, ramps, stairways and entrances. As a result, the study found that application of Universal design of community spaces in apartment complexes were evaluated relatively low. The environment of community space in apartment complex is not considered the blind, deaf, disabled, children and aged people because the application of these categories doesn't be enforced a law. Hence, Universal design regulations and design guidelines were established to satisfy residents of apartment complex.

Today travel demand continues to increase with spread of economic zones. Also, urban freeway plays an important role in intra-zone transportations as a major corridor in a big city. However, most of urban freeways experience a severe congestion with the excess of inflowing or outflowing traffic through freeway ramps. The purpose of this study is to identify the traffic characteristics, analyze the relationships between the traffic characteristics and finally construct the speed predictive models on the ramp junctions of urban freeway under the intelligent transportation system(ITS) settings. From the analyses of traffic characteristics following results were obtained: ⅰ) 24 hours average traffic characteristics flow, occupancy, speed under the ITS settings showed about 40%, 38%, 8.8% increase each on urban freeway junctions period when compared with that under the non-ITS settings each other. Free flow speed and traffic flow on the mainline sections of urban freeway under the ITS settings also showed about 20% and 17% increase when compared with that under the non-ITS, respectively. ⅱ) The upstream when compared speed( $S_{u}$)and downstream occupancy( $O_{d}$) were especially shown to have higher explanatory powers on the stable flow ramp junctions, but the upstream speed( $S_{u}$) and downstream flow( $V_{d}$) were especially shown on the unstable flow ramp junctions of urban freeway under the ITS settings.ngs.ngs.

L/UL(Load/unload) mechanism has been widely used in SFF(Small form factor) HDD because L/UL technology has many advantages such as an increase of areal density, reduction of power consumption and improvement of shock resistance. In this system, the most important design goal is no slider-disk contact and fast air-hearing breaking during L/UL process. To do so, we should consider many design parameters related to L/UL system. The ramp shape is the most dominant component among parameters which dramatically affect the L/UL performance. This paper makes an advanced ramp model using ANSYS/LS-DYNA. Through this FE model, this paper investigates the effect of initial ramp slope and location of air-bearing breaking. From the experiment for three different ramps, we also verify that experimental results agree with simulation results. We conclude that the ramp design should have small ramp slope at the moment which a suspension tap contacts with ramp and large ramp slope after air-bearing breaking in order to improve L/UL Performance.

This study analyzed visual-perceptual centrality as a measure to solve the confusion that might occur in visitor's movement in analyzing contemporary museums that have recently expand. Also, this study proposed a new methodology to understand the relationships of the occurrence and convergence of visual-perceptual power. The existing visibility graph analysis mostly ends up in identifying nodes corresponding to the physical environment of museums while the newly proposed visibility graph analysis is a methodology that can analyze the landmark on which the visual-perceptual power occurs and converges, by setting visible space elements as analysis variables, which showed a possibility to draw more reliable results in parallel to the existing analysis, and the results of this analysis are as follows. A public museum located in downtown has a limitation that it cannot but be multi-layered as a way to enlarge for the accommodation of a variety of programs on a limited site. Also, this study found that the problem of visitor orientation occurring in the multi-layer process was solved by a major space which was visual-perceptually void. Also, its types can be summarized into two types: One is setting parameter spaces (ramps, staircases, hallways) linked visual-perceptually to the major space and the other is solving the confusion of the visitor's movement by composing a simple exhibition space. In particular, it is judged that the type solving the confusion of the visitor's movement by composing a simple exhibition space also had a relationship with changes in the characteristics of the exhibited works by period. In addition, it was found that the entrance also appeared in two types: dependent type and independent type in the major space according to the characteristics of the major space.

Purpose: This study examined two trunk strategies - medio-lateral ramp and anterior-posterior ram - and their effects on pelvis and trunk movements, providing basic material for safe ramp utilization. Methods: The present study included 20 asymptomatic males recruited from a local university. Participants were asked to stand with their feet shoulder-width apart. Their dorsal side faced the camera, and measurements were performed while standing in a neutral double stance, one leg stance, $15^{\circ}$ of medial and lateral ramp, and $15^{\circ}$ of anterior and posterior ramp. Participants were allowed to practice for 3 minutes, and each participant had a 30 seconds rest between the two ramp conditions. One-way repeated measures analysis of variance was used to determine the effects the ramp conditions on spinal alignment. In all analyses, p<0.05 was used to indicate statistical significance. Results: The trunk-inclination angle on the posterior ramp was significantly lower than that of the double stance position (p<0.05). The trunk imbalance angle was significantly higher on the medial ramp, than that on the double stance position (p<0.05). The pelvic position and pelvic torsion angles were significantly higher in the medial, lateral, and anterior ramp positions than that of the double stance position (p<0.05). The pelvic rotation angles on the medial, lateral, and anterior ramps were significantly lower than that of the double stance position (p<0.05). Conclusion: These findings suggest that when people are exposed to the same form of ramp for an extended period, posture modifications may be triggered.

This study examined perceived discomforts encountered in residential facilities such as individual houses and apartments, and suggested a procedure for improving the problems in the living residence. The participants consisted of two groups of people: normal and underprivileged people; the underprivileged group was classified into 3 sub-groups: elderly people (over 65 years old), handicapped people and pregnant women. To identify inconvenient places and design factors in the residential housing, a total of 200 subjects (50 for each group) participated in the survey using the 7-point Likert scale. As a result, all the user groups mainly answered a high degree of discomfort due to narrow parking places, doorsills, and height differences between floors. The elderly, the handicapped, and the pregnant women replied that it is uncomfortable to use ramps and utility rooms. In a follow-up study, one-to-one in-depth interviews were conducted with some of the participants to analyze the detailed causes of inconvenient places and design factors. This study also suggested the procedure for solving the problems in various design factors from perspective of universal design, by considering prior studies which focused on a certain user group like the elderly. This procedure was suggested to consider as many user groups as possible at the same time. The results can be used to understand the discomforts of various user groups on residential housing. The procedure can also be used to develop universal design guidelines for the living residence.
