After studying several methods of the high efficient use of a treatmented sewage in anticipation of the future shortage of the duty of water, we could have some conclusions as the following : 1. Advanced treatment systems are essential prerequisites in rersing a treatmented sewage. 2. In a short term, the application of reusing a treatmented sewage should go first to new building areas near the sewage but for the long run, it should cover the whole area of Taegu, it is desirable that the pipe line networks which include dual water systems as well as water supply should be spread throughout the whole city. 3. The city authorities have to make every effort to step up publicity activities on this plan to all the citizens and building owners to steadily carry out this project and encourage private constructors to participate with the help of SOC. And for the long run, it is desirable that the application of reusing a treatmented sewage should be obligatory.
The object of this study is extraction of the method which can solve the traffic problems of Taegu area and satisfy the development of the circumference area by organizing efficiently the uneffective system of the highway network(outer belt) which is penetrating Taegu area, so harmonizing the long-distance traffic which is the main function of highway. and it is important subject that the traffic planning and the development project should be established and progressed in broad area stanard.
It is necessary to establish a link organization to device the transportion planning relieving traffic congestion. Therefore, this study has established a principal link centering around Taegu city, and reviewed the efficienay of the grade intersations and the 3-Dimensional intersations. The results of this study are as fallow; This study has established each circulation lane by Grid partition and Daiiy Traffic Volume (the 1st circulation lane; 000m, the 2nd circulation lane; 800m, the 3rd circulation lane; 1000m) The delay model of a length is t₂= exp(3.0091 +0.001242x)k (R²=0.78). The conversion of traffic volume into turning point the grade and 3-Dimensional intersection at single intersection is different by the distance between intersections. The decrease of total link delay is minute by one or two 3-Dimension on a intersection, and the 3-Dimension on the 2nd and and circulation lane is more effective than the 1st circulation lane. In the case of multi-intersections, passing time on the 3-Dimension passing throuth the urban center and the bypassing road has a little difference. For that reason, the bypassing route must be considerd instead of the 3-Dimension passing throuth the unban center. So an examination and re-settlement of the future pricipal link is necessary to organze the principal link on Taegu city using other factor.
In this paper, ADSL function of ATM switching system has been examined and ADSL service test has been performed in real enviroment. The customer service loop range and its performance evaluation of 10^(-7) cell losses specification has also been tested in order to provide general customers with ADSL service using pair line that can be operated via already established voice telephone subscriber line on ATM. In addition, it can be thought that, with careful consideration, there is no trouble to apply ADSL technique nationally. The test results show that very high speed information telecommunication network of over 2Mbps can be worked with fair line condition of 3.7km, representative line noise condition of 3.4km, and 3.35km in the worst case(each cases the diameter of line is 0.4mm). Therefore ADSL technique with ATM can be applied to national subscriber line, and further more this technique will be appropriate service medium that can reduce the enormous investment and the construction term of national very high speed information telecommunication network.
대부분의 스테레오 쌍 압축 기술들은 왼쪽 영상과 오른쪽 영상의 중복도를 효율적으로 제거하기 위해 블록 기반 압축 기술을 사용한다. 일반적인 블록 정합 방법의 경우는 왼쪽과 오른쪽 영상간의 불일치 맵을 구하여 스테레오 쌍의 중복도를 제거한다. 본 논문에서는 스테레오 쌍의 에지믈 사용하여 에지 블록 정합을 통해 스테레오 쌍을 압축하는 방법을 제시한다. 스테레오 쌍의 왼쪽과 오른쪽 영상의 에지 분포는 거의 비슷하므로 에지 블록 정합을 통해 왼쪽 영상으로부터 오른쪽 영상을 복원할 수 있다. 이 때 보간 맵과 축소 맵을 생성하여 전송을 하게 되며, 이것들은 일반적인 블록 정합을 통한 불일치 맵보다 적은 정보량을 가지게 되어 효율적인 압축을 할 수 있다.
In this paper, we consider the architecture of integrated wired/wireless network architecture deployment on the basis of intelligent network. The most important facts in evolving to integrated wired/wireless network are to introduce B-ISDN as a core network, and to integrate service functions and control functions into an advanced intelligent network. We first consider the structure of broadband integrated wired/wireless network. The functional structure for wireless ATM and the evolution trends of wired/wireless system are discussed. Second, the evolution strategy of broadband integrated wired/wireless network and its structure are presented. Finally, the required technologies for broadband integrated wired/wireless services are classified and discussed.
The use of bicycle is economical, convenient and beneficial to the health. However using bicycle are few because of danger to conflict with car. Therefore, this study tried to find a method to activate the use of bicycle-lane Taegu city. The results of this study are as follows; Frist, A replacement of incidental facilities is necessary for bicycle-road Second, A play using the site of the closed railroad on Taegu railroad can be considered to expand bicycle-road. Third, To build bicycle-road, using shoulder-road may be effective . Especially, on the link operating bus only lane system, the safety and confotableness of the user of bicycle may become higher. Finally, transform facility and bicycle parking area must be equipped on the node between the suburbs and the urban center.
주파수 자원이 한정된 열악한 무선환경하에서 오늘날 AMPS방식의 셀룰러 이동전화 시스템에서는 급증하고 있는 가입자 수요에 대처하기 위해서는 효율적인 셀 계획 및 채널할당이 무엇보다도 중요하다. 특히 트래픽 밀집지역인 대도시의 경우 급증하는 이동전화 가입자 수요에 대처하기 위해서 시스템 용량만을 고려한 주파수 재사용패턴을 사용한다면 주파수 간섭으로 인한 혼선문제가 더욱 심각해질 수 밖에 없다. 본 논문에서는 지형과 도심환경을 고려한 셀룰러 이동전화 시스템에서 N=7과 N=5의 주파수 재사용 패턴을 사용하였을때 동일채널간섭비를 대구광역시에 적용 비교 분석하였다.
The definition of data mining is the non-trivial extraction of implicit, previously unknown and potentially useful knowledge from data. Also, data mining has been worked on various fields such as database, machine learning, statistics, expert systems, and data visualization, and is a process consisting of these techniques. In many E-Commerce applications, it is important to build personalized profiles of individual users from their transaction histories. These profile constitute models of individual user behavior and can be specified with sets of rules learned from user transactional histories using various data mining techniques. In this paper, we present a MAS (multi-agent system) for customer management which maintains personal user information automatically, commands retrieval of products according to user preference, and builds personalized profiles of user.
