This study was performed to analyze the effects of a water circulation green area plan on non-point source pollution in Gimhae South Korea. A quantitative analysis of Arc-GIS data was conducted by applying a watershed model based on Fortran to investigate the changes to direct runoff and pollution load. Results showed that prior to the implementation of the water circulation green area plan in Gimhae, direct runoff was $444.05m^3/year$, total biological oxygen demand (BOD) pollution load was 21,696 kg/year, and total phosphorus (TP) pollution load was 1,743 kg/year. Implementation of the development plan was found to reduce direct runoff by 2.27%, BOD pollution load by 1.16% and TP pollution load by 0.19% annually. The reduction in direct runoff and non-point source pollution were attributed to improvements in the design of impermeable layers within the city.

The purpose of the thesis is to explore ways of improving the quality of urban life by analyzing the Luzinterruptus's work looking for a new perspective on the relationship between environmental color and society. The street artist Luzinterruptus was born in Spain, is a leader in the field of New Genre Public Art brush on a canvas of light in the night. They should seek the views of other common color system and color environments. The method of research is urban design, we consider the concept of the public good understanding, and New Genre Public Art. It also analyzes the environmental color of Luzinterruptus to take advantage of the phenomenology by David Katz color classification. The scope of the thesis is focused on the analysis of the works featured in their website and webzine. Then select a sculpture installation information is stated on the environmental color of their work. The role of environmental color in their work is not an aesthetic experience of harmonious urban landscape was seeking Public Art. The citizens of the area and the installation work themselves. Also it listed as demolition after the exhibition to realize the difference with other people and take advantage to environmental color. Therefore, they the contemporary agenda in many part of narrative takes in the garbage or disposables that you can easily look at our surroundings, In addition, citizens are directly experiencing the fantastic custom-made lights and colors and objects of the oversize as a potential recalls memories. Thus, the use of environmental color comfortable life there is horizontal participation and communication of the 'citizens' critical perspective of the 21st century cumulative cities.

The purpose of this study is to identify the perceptual differences among independent elderly relative. to falls risk associated with specified environmental design factors. The sample consisted of 135 independent elderly who live in Ulsan. The data were collected by utilizing questionnaire which included demographic information, and environmental design assessments accompanied by line drawings. The data were analyzed by using SAS program. The major findings were as follows: (1) There were 35(25.9％) elderly experienced fall(s) within one year and about half of the fallers fell more than once. (2) The elderly perceived lighting is the most hazardous interior design factor related to increased risk of falls. (3) There was a significant difference among age groups on perception of lighting as interior design factors and the elderly perceived differently floor as interior design factors by their perceived health status.

The design variables for structural systems, in most practical designs, are chosen from a list of discrete values, which are commercially available sizing. This paper presents the application of Genetic Algorithms for determining the optimum design for two-dimensional structures with discrete and pseudocontinuous design variables. Genetic Algorithms are heuristic search algorithms and are effective tools for finding global solutions for discrete optimization. In this paper, Genetic Algorithms are used as the method of Elitism and penalty parameters, in order to improve fitness in the reproduction process. Examples in this paper include: 10 bar planar truss and 1 bay 8-story frame. Truss with discrete and pseudoucontinuous design variables and steel frame with W-sections are used for the design of discrete optimization.

This paper proposes a novel iterative procedure for the design of planar reinforced concrete structures in which the reinforcement is designed for stresses calculated in a nonlinear finite element analysis. The procedure is intended as an alternative to strut and tie modeling for the design of complex structures like deep beams with openings. Practical reinforcement arrangements are achieved by grouping the reinforcement into user defined horizontal and vertical bands. Two alternative strategies are proposed for designing the reinforcement which are designated A and B. Design constraints are specified in terms of permissible stresses and strains in the reinforcement and strains in the concrete. A case study of a deep beam with an opening is presented to illustrate the method. Comparisons are made between design strategies A and B of which B is shown to be most efficient. The resulting reinforcement weights are also shown to compare favorably with those previously reported in the literature.

The environment and the ecologic balance of the earth had been destructed by both man and ecological catastrophes and are no longer sustainable. We have no future unless we conserve our natural resourses and make efforts to change our basic patterns of consuming, production and recycling. Our earth had been contaminated without our recognition. We became indifferent to environmental problems and even more we hve lost our interest completely. To overcome this period of crisis, the concept of 'green imperative'has emerged. Since design powerfully influences our lives and the environment for good or ill, those at the forefront of design to consumers and the end-users can contribute to the well-being of the people and planet through new awareness of environmental and ecological based design. The spiritual awareness of green design will enrich the work of design through lasting performance of continuty and will make the future work.

Passive treatment systems are commonly used for remediation of mine drainage waters because they do not require continuous chemical inputs and operation. In this study, the selection and design criteria for such systems were evaluated, particularly the two most commonly used ones, i.e., permeable reactive barriers (PRBs) and vertical flow biological reactors (VFBRs). PRBs and VFBRs are operated on the same principles in terms of biochemical reaction mechanisms, whereas differences relate to configuration, engineering, and water management. In this study, each of these systems were described with respect to key design variables, such as metal removal mechanisms and removal rates, effectiveness and longevity, general design and construction, flow capacity, and cost. The information provided from this study could be used as a design guideline when a passive treatment option is considered for potential remediation of a mine site.

The design of truss type sign support structures is based on the guidelines provided by the American Association of State Highway and Transportation Officials Standard Specifications for Highway Signs, Luminaries and Traffic Signals and the American Institute of Steel Construction Design Specifications. Using these specifications, the column design strength is normally determined using the effective length approach. This approach does not always accurately address all issues associated with frame stability, including the actual end conditions of the individual members, variations of the loads in the members, and the resulting sidesway buckling for truss type sign support structures. This paper provides insight into the problems with the simplified design approach for determining the effective lengths and discusses different approaches for overcoming these simplifications. A system buckling approach, also known as a rational buckling analysis, is used in this study to determine improved predictions for design strength of truss type sign support structures.
