ArcView and water network models have been integrated to develop the water network modeling system based upon GIS. To develop this system, pre, main, and post processing systems are required. GIS programming technique was adopted by using the ArcView's script language Avenue. The input data of models have been prepared by using the AutoCAD Map3D through the conversion of modeling input data to GIS data for A city. The modeling has been implemented by using EPANET, WaterCAD, InfoWorks. To develop the post processing system, the modeling results of the water network models have been analyzed by using GIS. During the application process of the developed system to B city with 300,000 population, main problems were found in the constructed GIS DB of that city. Thus, pilot study area of B city has been constructed, and pre-, main, and post-processing techniques were invented based upon GIS. Finally, the problems related to waterworks GIS projects in Korea were discussed and solutions were suggested.

This study was inverstigated on that a street view is the important point of the town planning. Until now, the street view has formed with senseless and coarse town planning because of lack of understanding of the street view during the urbanization in the same way and total lack of a consistent plan. On the sight of having a critical mind about the street view, this study was performed to present the analyses of the current problems of the street formation as the vivid directions of development for the future city view of the visual quality and the development of comfort.

A number of problems associated with environmental noises in urban areas have significantly been considered. Specific measurement and estimation of the environmental noise became a primary issue in local governments. Environmental noise monitoring system is required in order to estimate and verify the a city noise map. However, current monitoring positions may not perfectly represent and incorporate many different view points, such as districts of a city, different utilizations of a city by the law, populations, and classifications and traffics of roads. In addition, scientific method to provide specific noise monitoring positions my not be avaliable in current literature. For this reason, the primary objective of this paper is to propose a new method for introducing a number of monitoring positions in the entire city. First, the quality function deployment (QFD) method was utilized to simultaneously represent both districts and utilizations of a city. Second, a new algorithm to find a number of monitoring positions was proposed by compromising many different view points: populations, classifications of roads and areas, and traffics of roads. Finally, the proposed monitoring positions and a sample noise map was provided for verification purposes. Based on these results, the proposed algorithm including the QFD concept may successfully provide specific noise monitoring positions by simultaneously consider may different view points and requirements of a city.

Management practices and ordinances for urban scenic view protection are varied by cities because they have their distinctive nature and social environment. Therefore landscape management methods for urban scenic views are generally varied by the characteristics of city landscape and ordinance. This case study for scenic view protection practices in U.S.A. is very meaningful and appropriate because cities initiate a plan and/or an ordinance to manage urban scenic view in Korea. Urban scenic view protection methods were analyzed based on followings: 1) how to select scenic view resources and define spatial areas for preserving them, 2) how to control building height, open view corridor and guide landscaping and 3) how to carry out view protection methods and organize them in laws or ordinances. Findings of this study will be applied usefully in the development of urban scenic view protection methods in Korea.

'[n this paper, we propose an efficient multi-view image coding algorithm which finds the optimal texture from a restricted number of multi-view image. The X-Y plane of the normalized object space is divided into the triangular patches. The depth of each node is determined by appling a block based disparity compensation method. Thereafter the texture of each patch is extracted by appling an affine transformation based disparity compensation method to the multi-view images. We reduced the number of images needed to determine the texture compared to traditional methods which use all the multi-view image in the texture extraction. The experimental results show that the SNR of images encoded by the proposed algorithm is better than that of images encoded by the traditional method by the approximately 0.2dB for the test sets of multi -view image called dragon, santa, city and kid. Image data recovered after encoding by the proposed method show a better visual results than after using traditional method.

Smart City is highly anticipated to solve the problems of existing cities and create new added value, but there is also increasing concern about security risks. The negative view of smart city according to security risk awareness is a problem that needs to be improved in order to activate the fourth industrial revolution technology and develop smart city. This study examined risk factors in smart cities based on perceived risk and user resistance theory, and empirically analyzed the relationship with resistance attitudes. According to the empirical analysis with 288 research samples, security, social, and physical risk factors directly affect smart city resistance, while financial, performance, and privacy risk have no significant effect. In addition, it was verified that the security risk can is an antecedent factor for other risk factors, and it was confirmed that it is required to separately discuss the security and privacy risk in the smart city environment. This study shows that it is necessary to prepare policy supports for social interactions as well as security and physical safety issues in order to activate smart city by discussing the risk factors that negatively affect smart city perception from the public's point of view.

The goal of this study is to identify the new Architectural type of house and Landscape design pattern of the collective housing area in American garden city, Midlothian near Richmond of Virginia. I had been surveyed old houses of the Virginia and new single family houses and landscape design style of Mariners village to find a different style of houses and lots. The Richmond, capital city of Virginia, is surrounded by five suburban areas and counties. One of them is the Chesterfield where it has main street of Midlothian garden city. The city of Midlothian has a function of residence area both to stay in the forest garden and to go to downtown office of Richmond. There are a lot of collective housing area out of the capital city. I surveyed house form, lots, and site design pattern of the Mariners village in Midlothian. The community of Mariners shows a particular characteristics and harmonious pattern of suburban residence area in a view point of new project. There are three results of this study as follows: First, the types of house in suburban garden city, Midlothian, are focused on vernacular Colonial style with country house, traditional house, and front gable house form which are an unique new American single home. Second, the landscape design of this collective housing area, the Mariners village, has a unity view of residence community, harmony between house and lots, and a sensitive cul-de-sac pattern and loops type with rational land using based on the forest topology. Third, the Mariners village shows that the design concept of landscape architecture has to consider of traditionalism, naturalism, and living condition of residents.
