The study was conducted to examine the possible psychological difference in visual preference for natural landscape depending on the residence characteristic of the visitors, with the aim to use as the reference when creating space for natural landscape. Visitors were classified into three groups, namely, urban, suburban, and rural residents, and their preferred type of landscape was surveyed. The result showed that regardless of their residence the highest preference was to the place with superior natural landscape features, and among such features the common preference was toward the landscapes with horizons and those with animals. Urban and suburban residents showed similar preference pattern, and there was artistically significant difference with rural residents. In this respect, the difference in preference for natural landscapes could be induced between urban and rural residents. Rural residents had similar preference with urban residents in that they both preferred the place with superior natural landscape features, but differed in that the former had significantly higher preference toward the landscapes that have mixed artificial elements. From the above research, the following conclusions can be inferred:for regions that need to create natural landscapes, differentiated visual landscape plans and strategies need to be established taking into account, inter alia, the natural richness of the neighborhood natural environment; for regions that need to conserve and manage natural environment and landscapes, the measures to adjust the natural landscape management plans need to be established taking into account the neighborhood environment of the protected areas and the number of visitors to the region.

On account of the increasing crime rates annually and the consequent rising anxiety, safety has become an important topic in the aspect of environmental formation to provide decent lives to urban dwellers. As a result, great emphasis has been placed in the importance of Crime Prevention through Environmental Design (CPTED), a design method which utilizes physical environmental design to prevent crime. The definition of CPTED encompasses the technological level of crime prevention as well as comprehensive environmental design which takes into consideration fear or terror in view of human recognition and emotion. However, the current application method of CPTED in Korea is still limited to the technical supplementation of facilities, such as CCTV and streetlight, and fragmental modification like village mural paintings. Moreover, the guideline for CPTED in Korea is only a theoretical adaptation of foreign books and does not offer sufficient studies for a practical design method that will improve the life of city dwellers. The purpose of this study is to examine design methods for safe environment construction in accordance with the changing concept of CPTED by understanding the characteristic of space and analyzing the how the methods of light are expressed. This study aims to provide basic material which will serve as a guideline in creating a safe environment in the future.

The purpose of designing Haebaragi park, legally designated as children park, is to make a place for children including residents performing outdoor recreation, various social interactions, and cultural activities. Design concept for space plan have twofold; the one is a positive and creative playing space and facilities for children, escaped from a monotonous playground, and the other is a cultural and social space for neighboring communities. The site having the area of 1,316.7 square meters, located in Nowon-Dong, Buk-Gu, Daegu metropolitan City, is just like a vest pocket park. The adjacent area had been developed a slum area with mixed ad visually conflicting land use patterns and low income groups. The children and residents living in the area do not have any public space suitable for playing and/or rest. After analyzing such locational characteristic as accessibility, land use of the communities, and potentials for park development, and such design concept as arrangement of facilities, efficient use of site, and functional allocation of park space, We have mad a plan for composition of spaces for various activities, provision of facilities based on estimation of user-demand and activities, and planting. In the design process, we have tried to harmonize functional spaces with facilities, and to organize all the functions as a whole. To improve urbanity and aesthetic shape of park design, we have introduced a central plaza, design of a pave floor, a torrent, large trees for shade, colonnades and so on. From this design project, we can develop the site as a children park for increasing creativities and various playing opportunities, and as a resident space for rest, cultural activities. In the future, it is required that many attempt to design and develop urban small space as a park for children and residents.

Purpose : As the number of the transportation poor has increased, the application of Universal Design on urban railway station has recently been focused. However, the current criteria used in domestic areas did not show the characteristic of facilities within urban railway station. Therefore, this study aims to explore the detailed criteria in applying ideas from Universal Design to sanitary facilities, especially toilets within railway station. Method : This study explores the criteria by evaluating findings from previous studies. First, the current situation of sanitary facilities in railway station is assessed. Then, the detailed criteria applicable to railway station toilets are concluded, by reviewing types of transportation poor and principles of Universal Design. Result : Findings from this study are as follows. First, the current criteria applied to railway station toilets lack ideas of Universal Design, so the better criteria applicable to sanitary facilities in railway station are necessary. Second, standard criteria used in domestic areas with newly additional criteria suggest that sanitary facilities should be established according to those criteria. Taken together, the better sanitary facilities should be provided to railway users through the application of Universal Design to railway station toilets. Implication : For the future users in railway station toilets, the additional research on types of diverse space and other sanitary facilities within railway station should have been continued.

Roadside pollution has been identified as the main cause of PM_2.5 in urban areas. Green infrastructure has been understood to mitigate air pollution from roadside traffic effectively, but complication depend on environmental variables. This study aimed to investigate the characteristic of PM_2.5 by the type of space in an urban park located in Songsanghyeon Plaza, surrounded by a 12-lane road on all sides. Type of space was typically classified as roadside square (A), sunken square (B), a mix of trees and hedges/shrubs (C), trees only (D), and grass square (E) according to the land-use type and layers of trees. PM_2.5 was measured for nine days, three days for three different Air Quality Forecasts-Good level (0~15㎍/m³), Moderate level (16~35㎍/m³), and Unhealthy level (36~75㎍/m³). The analysis result was as follows. At good levels, there was statistical significance in the order of D, E < B, C < A. In the case of moderate levels and unhealthy levels, D and E were statistically lower than other land-use types. The characteristic of PM_2.5 in the urban park by type of space was affected by atmospheric flow into the road. The relatively high concentration of A and C was located near the roads. Although B was far away from the road, the reason for the high concentration of PM_2.5 was that no structures blocked the air pollution. Thanks to the type of space C, filtering the air pollution from the roads, the concentration of PM_2.5 in D and E was relatively low.

In this study, the numerical model was developed to evaluate the observational environment of sunshine duration and, for evaluating the accuracy and utility of the model, it was verified against the observational data measured at Dae-gu Automated Synoptic Observing System (ASOS) located in an urban area. Three-dimensional topography and building configuration as the surface input data of the model were constructed using a Geographic Information System (GIS) data. First, the accuracy of the computing planetary positions suggested by Paul Schlyter was verified against the data provided by Korea Astronomy and Space Science Institute (KASI) and the results showed that the numerical model predicted the Sun's position (the solar azimuth and altitude angles) quite precisely. Then, this model was applied to reproduce the sunshine duration at the Dae-gu ASOS. The observed and calculated sunshine durations were similar to each other. However, the observed and calculated sunrise (sunset) times were delayed (curtailed), compared to those provided by KASI that considered just the ASOS's position information such as latitude, longitude, and elevation height but did not consider the building and topography information. Further investigation showed that this was caused by not only the topographic characteristic (higher in the east and lower in the west) but also the buildings located in the southeast near the sunrise and the southwest near the sunset. It was found that higher building resolution increased the accuracy of the model. It was concluded that, for the accurate evaluation of the sunshine duration, detailed building and topography information around the observing sites was required and the numerical model developed in this study was successful to predict and/or the sunshine duration of the ASOS located in an urban area.

As the problem of destroying natural environment is emerging as a common social issue world widely, recently in the filed of architecture there has been increasing interests in environment-friendly architecture according to the awakening and understanding of environmental pollution. The social problem caused by pursuing affluent urban life is now making the quality of life an issue against the urban policy that has been simply emphasizing quantitative expansion only. Accordingly, development and popularization of such a type as environment-friendly low-rise house is being suggested as an alternative idea, because it can combine secured independent space, which is a merit of independent houses, and characteristic architectural shapes, making possible the development of large scale environment-friendly complexes. Based on the analysis of the examples of Environment-friendly low-rise house in other countries that are utilizing amenity concepts, such as environment, ecology, culture and history, the present research proposed an alternative idea for highly dense high-rise houses, by resolving the problems of low-rise house complex caused by the variable of ecological environment. An effort was made to understand the concept of low-rise house through theoretical investigation, and based on the analysis of domestic and foreign cases, a method for improving the problems was deduced as a conclusion.

The core aim of this dissertation is to empirically scrutinize a strength characteristic of beam-column frame subjected to the cyclic lateral load, a beam-column frame of un-reinforced masonry wall, and a shear wall frame. First and foremost, I embark upon making three prototypes vis-$\grave{a}$-vis this research. By conducting this process, I touch on an analysis of cyclic behavior and a damage characteristic of the beam-column frame, the beam-column frame of un-reinforced masonry wall, and the shear wall frame. What is more, through the previous procedure, the next part delves into the exact stress transfer path and the destructive mechanism to examine how much and how strong the beam-column frame of un-reinforced Masonry Wall does have a resistance capacity against earthquake in all the architecture constructed by the above-mentioned frame, as well as school buildings. In addition to the three prototypes, two more experimental models, a beam-column frame and shear wall frame, are used to compare with the beam-column frame of un-reinforced masonry wall. Lastly, the dissertation will suggest some solutions to improve the resistance capacity against earthquake regarding all constructions built with non bearing wall following having examining precisely all the analysis with regard to not only behavior properties and the damage mechanism of the beam-column frame and the beam-column frame of un-reinforced Masonry Wall but also the resistance capacity against earthquake of non bearing wall and school buildings.
