This study is to examine and classify the phasic characteristics of organic thoughts in modern architecture. Organic architects have applied organic thoughts to solutions for the problems of each period in architecture since modern times. As results of this study, the architecture of organic thoughts from 1850s to 1940s could be divided into two phases. The phasic characteristics of the first phase from 1850s to 1910s was physical resemblance in real or fantastic appearance that the work of art and architecture should imitate organic forms from the view of solid empiricism. The phasic characteristics of the second phase from 1920s to 1940s was organic growth that the form appropriate to a work of art and architecture should grow from the nature of the problem itself as a system in nature grows from the view of pragmatism and was organic unity that the form and function or the form and content of a work of art should be inseparably integrated as the form in nature should grow out of the inner nature of the thing and be an expression of that inner nature from the view of expressive theory.

The performance of radars operated near an offshore wind farm region may be degraded due to the distorted signals by wind turbines. This degradation of radar systems includes ghost effects and doppler effects by a tower, nacelle, and turbine blades consisting of the wind turbine. In this paper, electromagnetic wave backscatterings from a offshore wind turbine are numerically simulated in terms of temporal radar cross section and radar cross section spectra, using a quasi-static approach based on physical optics and physical theory of diffraction. The simulations are carried out at 3.05 GHz for the seven yaw angles and four blade pitch angles. From the results, radar cross section values and doppler effect as turbine blades rotate are investigated.

In the study I analyzed the relationship between the characteristics of the user's residential environment and his or her use of openspace. I find out that there are little correlationship between building form and use factors. Also, there are no relationship between persons per room and use factors. Only the physical distance and the location of the building site is correlated with the use factor. In testing the hypotheses, I discovered very little to support the "physical deterministic" notion. I generally was not able to explain the behavior of open space users on the basis of the physical parameters selected to describe the user's residential environment. This, I believe, indicates that there probably are many other variables that play a more important role than those pertaining to the density and form of the residential environment. It is necessary to find out more variables affecting the use of openspace in the neighbourhoods, such as the charecteristics of user group. Also, it is necessary to apply the study to the other sites or the other cities in Korea to compare with the results.

Traditional markets located in local small towns have effected local economies and culture for a long time, but their current situation is not so good. In this context, this paper tries to find out the physical characteristics and problems of local traditional markets and to extract some suggestions to improve them. For this, I selected three traditional markets as case study areas such as Mugeuk, Samseong, and Boeun located in local small town in Chungbuk Province. Using the diverse survey methods including theoretical review, basic data analysis, field survey, and questionnaire study, I examined physical features such as location, spatial structure, type of business, streetscape, and convenient facilities in the designated markets. Finally, based on this, I proposed some suggestions on the improvement of traditional markets located in local small towns as followings; expand and improve the convenient facilities, enforce the image of entrance, boost and form groups of specified business, reflect the local characteristics, and amend the related institution etc.

This paper proposes a design technique of a survivable ship backbone network, which describes a near optimal configuration scheme of physical and logical topologies of which the survivable ship backbone network consists. We first analyze and present an efficient architecture of a survivable ship backbone network consisting of redundant links and ship devices with dual communication interfaces. Then, we present an integer linear programming-based configuration scheme of a physical topology with regard to the proposed ship backbone network architecture. Finally, we present a metaheuristic-based configuration scheme of a logical topology, underlying the physical topology.

The purpose of this study is to understand the relationship between physical characteristics and general people's perception. In this study, the physical quantities of artificial lighting were measured from the visual point of the pedestrian and general public perception including preference and satisfaction was examined. As a result of this study, the total luminance and mean luminance had different value in each site. However, there were no significant differences in area and number of light source between sites. The effects of these factors are affected by indoor lighting. In the group of respondents, 10s people, male, students, meeting, 1~2 times a month and 18:00~20:00 had higher satisfaction compared to other groups respectively. A total luminance and mean luminance gave effect on the satisfaction of physical quantities of artificial lighting and the satisfaction on night landscape. With increase in total luminance and mean luminance, the satisfaction was lowered. It is necessary to reflect these factors on the future policies of nightscape.

The study aims to identify factors related to landscape structure and socioeconomic characteristics that influence adults' physical activity and health. The study analyzes data from 148,643 respondents from the Korea Community Health Survey conducted in 2021. The study measures various factors, including the frequency of physical activity, stress, depression, and landscape metrics of forest patches. Hierarchical multiple regression analysis was used, controlling for socio-demographic characteristics. Larger forest patches and more irregular shapes are associated with higher levels of physical activity among adults. The percentage and area of the forest patch are associated with fewer mental health complaints. Configuration-related landscape metrics such as shape or arrangement of the forest patch did not show a significant association with physical activity. Overall, the study provides insights into how specific characteristics of forest patches in urban areas may influence physical activity and mental health among adults. It emphasizes the importance of green spaces and their potential positive effects on both physical and mental well-being.

Luis Barragan's Architecture has creative feature that Mexican environment and traditional culture were complete by color. Thus the color of his work makes our emotions rich and colorful. He said "My architecture is autobiographical..." at speech in Pritz price. As we can see in his architectural philosophy that sentimental architecture is important than theorical system, his works are impression of empirical factor with intuition. "Color is a complement to the architecture. It serve to enlarge or reduce a space. It's also useful for adding that touch of magic a place needs", stated Barragan. During his process of shaping space, Barragan drew on color in the same way as an architectural component, according it a spatial funtion and expressive vale. he allied it with light, deeming it a crucial vehical for conveying the emotive attributes a site. The capacity of color to express sensitivity and sensuality within an architecture space is liked to its psycho-physiological qualities. In this kind of view, color featyre in Barragan's work is one of the most important tools to realize sentimental architecture, not only is result of the Mexican regional color. As a result, make focus on analyzing various meaning of the color in Barragan's architecture like poetic and habitable structure.

Data grid shares distributed large data via wide-band network. Such grid environment consumes much time for large data transmission. Because it is implemented on internet as physical network. Many replication strategies were proposed for solving this problem, but they are not optimal in real Data grid environments. Because they were proposed that based on logical topology without consideration of real internet architecture. Grid data access time is largely influenced by internet architecture as physical network of Data grid. In this paper, we propose a new data replication strategy RSIA(Replication Strategy based on Internet Architecture) based on internet architecture. The RSIA places replicas considering structural hierarchy in each element of internet, and avoid the performance bottlenecks to reduce system performance degradation when a data transfer. Through simulation, we show that the proposed RSIA data replication strategy improves the performance of Data Grid environment compared with previous strategies.

Rapid social changes and scientific advances of the $21^{th}c$ have brought on a major paradigm shift towards consilience, making boundaries more or less irrelevant. In the field of architecture, this is manifested in the emergence of colors that can be described as 'being aleatory', 'non-formal', 'non-deterministic' and 'perpetually evolving'. Contemporary architectural colors are not definitively fixed. They are rather liquid and metaphorical. Whereas the more traditional architectural colors have delivered clearly and precisely the intended symbolic meaning and visual information, those of today are less definitive and embody a more liquid and conceptual value system. This paper discusses the denoted signification and the meaning effect of the metaphorical color system found in contemporary architecture. This paper analyzes works of architecture from the late 20th century, when dramatic change sin architectural color system surfaced, to the more contemporary creations. Here, three categories of color are suggested, namely material color, spatial color and liquid color. Each categories considered in connection with deconstruction, holistic interactivity and the multiplicity of meanings that may result as information from the external world is perceived as stimulus to the inner mind. Contemporary architectural color scheme is characterized by its unpredictable vagueness of meaning, synesthetic engagement of imagination and chance, and expansion of the inner and outer world, all of which contribute to a metaphorical effect. The metaphorical color system of contemporary architecture can be classified into three dimensions, and it connects with human consciousness and amplifies itself through flexible and fluid communication. In this process non-physical colors materially serve as formal logic and room for varied interpretation of architectural space and our conceptual framework.
