After latter half of the 1990 it has come out urban decline in big and middle & small cities. The purpose of this study is to review the methods of resident participation for community revitalization in civil renaissance through literature study. This study is divided into fourth parts. In the first part, the history of civil renaissance in Japan, German and England for getting grip on the situation is studied. In the second part, concepts of resident participation and community is dealed with. And the tendency of resident participation for community revitalization in civil renaissance is investigated through preceding researches. The third part and the last one are methods and conclusons and suggestions of resident participation revitalization in civil renaissance.

The purpose of this study is to present systematic information and direction to urban underground space development industry, civil engineering and R&D. Regarding the development of urban underground space, the situation in Korea, especially now in Seoul, can be called an underground Renaissance. The Superground project, which has been going on for several years through international competition, is now completed and is about to open the Seoul Architecture Museum. Leading underground space complex development project of Yeongdongdaero, which is the largest living underground space in human history, spectral projects such as the Seoul section of the GTX routes, making underground roads of the Dongbu Expressway and the Seobu Expressway are now speeding up progress. Recently, plans have been made to use the underground more actively through the restructuring project of Gwanghwamun Square, the face of Seoul. And then, patents are indispensable resources for establishing a strategy for R&D as one of the indices showing what technologies have been developed and what technology development will be done in the future. Based on this background, this study attempts to classify and define the technical elements of urban underground space development through the analysis of patents of major countries in the world, and analyze and present state of technology level and situation accordingly.

Since late 1990's the urban decline phenomenon has risen in most provincial cities in Korea. Many lively discussions have also risen about how to revitalize declined urban center. In small cities, especially resident participation is very important to revive their old vividness. The study then reviewed literatures published from 1995 to 2007 regarding resident participation in urban center revitalization for community reinvigoration. This study consists of four parts. The first part defined concepts of community and of resident participation, and included discussion about resident participation codes. In the second part, the problems about community formation and community facilities were scrutinized through preceding researches. The third and last parts suggested some propositions and strategies to draw resident participation into urban center revitalization.

The Endless Column by Constantin Brâncuşi is "the most radical sculpture in the history of classic modernism", "the only one of modern times that can be compared with the great Egyptian, Greek and Renaissance monuments". It "is not only an artistic masterpiece, but also an extraordinary feat of engineering", the greatest example of collaboration between a sculptor and an engineer. This article illustrates the path that led the artist to conception of the column, its planning and construction, the investigations on preservation of the monument and its restoration, the aerodynamic tests in the wind tunnel, the modeling of the wind and the structure in virtue of which the aeroelastic instability, dynamic response and fatigue life were investigated. The conclusions discuss the column's role in the panorama of the great works of modern engineering.

Korea Train Express (KTX) is now leading the train industry, heralding a new renaissance of transportation and changing the old construction-oriented policy to one based on customers' needs that intends to offer better service in speed, convenience, and space creation around the railroad stations. These new policies aims to provide differentiated 'utility' based services, with the commitment to environmentally friendly 'green growth'. Nevertheless, the new policy has the unspecified 'public' as its target and tends to change bus users to train users rather than automobile users to train users. Furthermore, due to the heavy dependence on automobiles, there exists the definite limit of the new policy to attract the automobile users to train services. The purpose of this paper is to analyze the car dependence in Seoul metropolitan area. Based on the analysis using structure equation modeling, it can be described that environment consciousness and public satisfaction level affect on the car dependence. Author concludes that emotional marketing needs to go with utility marketing and Incentive marketing to weaken the heavy dependence on automobiles and to successfully prompt the change to train services.

This essay traces the origin and the social function of medieval knights in Edwin Austin Abbey's murals ${\ll}$The Quest of the Holy Grail${\gg}$ in the Boston Public Library. Medieval knights in the Arthurian legend appeared in American novels at the end of 1850s and in political cartoons in the 1870s. They are featured in American Renaissance murals as well. ${\ll}$The Quest of the Holy Grail${\gg}$ painted in 1895 was the first of its kind. In Britain, the Pre-Raphaelites frequently painted medieval knights. Abbey fused the visual idiom of the Pre-Raphaelites and that of the Royal Academy of Arts in his depiction of knights. Unlike the Pre-Raphaelites, who usually focused on knights' activities, he emphasized their virtue. His representation of knights reflect the social and economic crises in America in the 1890s. After the Civil War, American society enjoyed economic prosperity but suffered from government corruption, economic inequality, and class conflict. Serious social problems such as poverty and inequality decayed American society. Writers and artists brought attention to these issues. This essay argues that Abbey criticized capitalists and expressed his hope for progress through the figure of Galahad as the iconic representation of civic virtue in ${\ll}$The Quest of the Holy Grail${\gg}$. Installed in the Boston Public Library, Abbey's murals performed a public function to warn the viewers of economic and social chaos resulting from government corruption. Abbey's American knights not only emphasized moral responsibility but also promoted patriotism. The artist refashioned medieval knights into American citizens, whose civic virtue became essential to an ideal leader in American society.

In water treatment plants supplying potable water, the management of chlorine concentration in water treatment processes involving pre-chlorination or intermediate chlorination requires process control. To address this, research has been conducted on water quality prediction techniques utilizing AI technology. This study developed an AI-based predictive model for automating the process control of chlorine disinfection, targeting the prediction of residual chlorine concentration downstream of sedimentation basins in water treatment processes. The AI-based model, which learns from past water quality observation data to predict future water quality, offers a simpler and more efficient approach compared to complex physicochemical and biological water quality models. The model was tested by predicting the residual chlorine concentration downstream of the sedimentation basins at Plant, using multiple regression models and AI-based models like Random Forest and LSTM, and the results were compared. For optimal prediction of residual chlorine concentration, the input-output structure of the AI model included the residual chlorine concentration upstream of the sedimentation basin, turbidity, pH, water temperature, electrical conductivity, inflow of raw water, alkalinity, NH₃, etc. as independent variables, and the desired residual chlorine concentration of the effluent from the sedimentation basin as the dependent variable. The independent variables were selected from observable data at the water treatment plant, which are influential on the residual chlorine concentration downstream of the sedimentation basin. The analysis showed that, for Plant, the model based on Random Forest had the lowest error compared to multiple regression models, neural network models, model trees, and other Random Forest models. The optimal predicted residual chlorine concentration downstream of the sedimentation basin presented in this study is expected to enable real-time control of chlorine dosing in previous treatment stages, thereby enhancing water treatment efficiency and reducing chemical costs.
