A regional planning is central to addressing various urban problems surrounding the detached housing areas of a metropolitan city of Daegu. The problems are related with decrease in population, socio-economic issues of redevelopment and a sustainable society, the various housing market and housing rights, and a need to explore a desirable alternative to enhance the civil needs when renovating General Residential Zone. The aim of this paper is to look into a possible method of residents led environmental improvement by surveying the residents' consciousness in low-density residential areas. The residents wish to have a residential parking permit program to be set up in place and financial support for old independent houses and finally for lampposts and CCTV to be installed by the administrative assistants. The 75.7 per cent residents who inhabit in the low-density residential areas wish that a residential environmental improvement plan is required and the population at 65.9 per cent could consider a need for the citizens to participate in the residential improvement. 70.3 per cent answered that a consultative group of inhabitants is needed to be built, while 40.5 per cent expressed that they would like to participate in that group in case the group is set up. The possibility of productive residential improvement via resident participation in the low-density residential areas is high, as long as small various environmental improvement projects are created, a resident-consultative group formed, and finally a residential improvement plan is addressed in a comprehensive way.

이 연구는 2005년 부산에서 개최된 APEC 행사의 안전활동 문제점을 도출하여 이를 토대로 향후 우리나라에서 개최될 국제회의 안전활동에 대한 제고방안을 모색해 보는데 그 목적이 있다. 이와 같은 목적을 달성하기 위하여 부산 APEC 행사에 직접 참여한 공안기관인 경찰, 소방기관의 공무원과 APEC 행사를 근거리에서 지원한 부산시 공무원을 대상으로 델파이방법에 의해 3차례에 걸쳐 의견을 수렴하여, 국제회의의 단계별 구성요소 및 문제점을 파악하고 구성요소별로 문제인식에 대한 통계처리를 실시하였다. 이와 함께 공안기관 전문가 4명과 1 : 1 면담결과를 통하여 국제회의 행사에 관한 안전활동 제고방안을 모색한 결과는 다음과 같다. 사전준비단계에서는 제 공안기관과 지자체의 사전협조로 안전활동에 대한 빈틈없는 기반을 강구하여야 한다. 현장활동단계에서는 각 기능별로 안전활동을 검토하고 지자체와 지속적인 보완작용이 필요하다. 실시단계에서는 공안기관과 지자체와의 긴밀한 협조에 의한 시너지효과로 안전역량을 제고해야 한다. 평가 및 수정단계에서는 행사종료 후 공안기관과 지자체가 합동으로 효율적인 평가시스템 탐색하여 차후 행사에 대비해야 한다.

Platforms of many railroad stations are crowded with passengers regardless of the time throughout day. But the intensity of illumination of the existing lightening systems are so low enough to make passengers feel inconvenience in using platforms. Consequently there exists high possibility of accidents in platforms of low illumination. Hence, for the safety and convenience of passengers, it is necessary to improve the luminous intensity of lightening system for platforms. This paper points out the problems of existing system and presents the method to improve it.

Recently, a structure has been large and high under the improvement of construction technique. So, mass concrete constructions that a mat foundation thickness of structure is over 80cm have been many. Also, in the reason of high strength of concrete, a matter of thermal crack became an important task to be solved. In this study, we executed temperature and stress analysis of mat foundation. And we evaluated quantitatively about the possibility of thermal crack by using hydration heat analysis program. Because of this analysis technique, we could control skilfully the quality of mat foundation in a construction.

This study aims at the development of REC sensor causing the gauge error in the hot strip rolling process, and the improvement of the hydraulic AGC (Automatic Gauge Control) system. The gauge error outbreaks from the various reasons, however, mainly the roll eccentricity is considered to cause a such kind of error. In the study, the REC (Roll Eccentricity Control System) sensor is designed using sensor An On - line test of the system shows the comprehensive effects of controlling the gauge error of the hot strip. On - Line test shows the possibility of enhancing the accuracy for gauge.

Making practical use of urban MAGLEV system which is tried by government includes technique development and railway construction. Because huge amount of money will be spent on this project, feasibility study is being carried out in order to check the feasibility and to devise the master plan in prior to making practical use of urban MAGLEV system. The key issues of feasibility study are possibility of technique development, economical feasibility, location of a model railway and the improvement of related laws and regulations. This paper shows the approach to solve these key issues.

The objective of this study is to investigate the possibility for application of E.P-dust as both admixture and fillers for aggregates under various mixproportion, replacing method and the ratios of replacement. According to the experimental results, improvement of viscosity and reducing of segregation at fresh state and gain in strength at hardened state can be achieved by applying E.P-dust. It can be considered from the results that application of E.P-dust will be more efficient as fillers for aggregates than as binder

The improvement of the situation on the Korean Peninsula, following the June 2000 Summit, has opened up the possibility of reconstructing the railway between the North and the South. The interconnection of the railway systems would allow cargo transportation from the south of the Korean Peninsula to Russia, China and Europe. This could open up a faster and more economical cargo transportation route than the all-water route.(omitted)

This study was carried out to examine the role soy milk in the preparation of Yukwa, possibility of substitution of soy milk to isolated soy protein and the effect of drying condition of Yukwa dough on the quality of Yukwa for the purpose of standardization of Yukwa preparation process. Although isolated soy protein did not make any particular effect on the gelatinization characteristics of waxy rice flour, soy milk lowered peak viscosity to half of waxy rice flour. The optimum moisture content of dried Yukwa dough was about 25%, and it can be reached by drying at $60^{\circ}C$ under atmosphere pressure for $4{\sim}5$ hours. On the basis of the results of morphological observations, mechanical and sensory measurement of hardness, and sensory test of the internal structure, mouthfeel and overall acceptability, soy milk was more desirable than isolated soy protein for the quality improvement of yukwa.

Recently, Peoples are exposed the ELF(Extremely Low Frequency) magnetic fields in the vicinity of underground transmission lines, and there are the generally accepted opinion that the magnetic fields affect the human body and there are possibility of the disease. Also in relation to this problem, technical solution methods and research are advanced for reducing the magnetic fields. In this paper, to practically understand the magnetic fields underground transmission lines, We analyze the electromagnetic field distribution in the underground transmission lines by means of FEM(Finite Element Methods) and present that improvement of the effective shielding methods by applying cable arrangements and shielding materials, eddy current problem to the underground transmission lines by means of the numerical analysis Tool.
