With a great interest in urban regeneration, it has been a critical issue for urban revitalization since 1980s in western countries. From the early of 1930's or 1940's after the World I, most of the nations such as UK and America had began to initiate urban renewal projects on the purpose of community development through the high density in the inner city for the major cities. The purpose of this paper is to suggest strategy of urban regeneration and growth of regional industry through the analysis of economic impacts on various sectors in Small and Medium-Sized Cities in Gyeongnam Province. Also it will be estimated for the future urban regeneration. This thesis is to analyze to some extent, the economic impacts of urban regeneration projects, in deteriorated districts of the city in relation to the urban regeneration projects which study the tendencies of various countries in the area of urban policies. From evaluating the economic impacts on diverse grounds in a need for urban regeneration, this paper hopes to raise the efficiency of policies from a new paradigm of urban projects.

An urbanization has been existed since ancient time in human history but it was started after the Industrial Revolution because of the effect of modern times in earnest. The modern Recently, the urban regeneration has made various impacts on urban development by social and economic as well as environmental and physical regeneration. Consequently, it has resulted in a holistic approach toward urban rehabilitation projects in more recent times. Therefore, the purpose of this paper is analyze the economic impacts of urban regeneration project under the industrial structure and consider effectiveness of policies by urban planning's new paradigm through the analysis of economic impacts for factors suggested by the necessity of urban regeneration under the industrial structure. For the analysis of economic impacts by each industry of urban regeneration project, the standard was the input-output tables presented by the Bank of Korea. The number of industrial sections were 28 and for the comparative years were 2000, 2003, 2005, 2007, etc. Compared with other results of analyses for large scale projects, it was proved that it had made large effects on various industries. As a result of the effects of urban regeneration in general, thepre-study and post-analyses of economic impacts are required as a part of the whole impacts of urban regeneration. Also, the economic impacts on all sectors should be applied to urban policies and techniques.

김남룡(Kim Nam Ryong),조성배(Jo Seong Bae),임정열(Lim Jeong Yeul) 한국방재학회 2018 한국방재학회논문집 Vol.18 No.3

대규모 필댐의 강진에 대한 구조물의 성능과 안전은 신규 건설사업 또는 시설물의 관리에서 중요한 요소이다. 보통의 공학 실무에서 설계의 검증이나 내진성능평가는 수치적 모사기법이 널리 활용되나 축소 모형을 이용하는 물리모형실험 또한 활용될 수 있다. 일반적으로 축소모형시험은 엄밀한 상사법칙에 따라 설계하고 수행하는데, 그러나 장비의 특성, 경계효과, 원형구조물의 특성 등 다양한 제약조건에 따라 일반적인 상사법칙의 적용이 어려운 경우도 있다. 본 논문에서는 이러한 물리모형실험의 제약사항을 살펴보고 대형 필댐의 지진응답거동 모사에 미치는 영향을 평가하였다. 또한 이러한 제약사항을 극복하기 위한 대안적 모사기법을 소개하고, 대형 필댐에 대한 원심모형실험 결과를 통하여 해당 모사기법의 적용성을 평가하였다. The performance and safety of large embankment dams subjected to strong earthquake ground motion is one of the major risks in new construction projects. The design and performance of the structure are generally verified by numerical methods in most of engineering practice, and reduced scale physical modeling is often carried out for the same purpose. In general, physical model tests are designed and carried out according to rigorous scaling principles. However, it is sometimes difficult to follow these principles due to various limitations; equipment, boundary conditions, characteristics of prototype structures, etc. This paper reviews the limitations of physical modeling and its effects in seismic performance evaluation of large embankment dams. It also introduces alternative modelling and testing methods to overcome the limitations. A test with a reduced scale embankment dam model have been carried out to examine the limitations and to verify the applicability of alternative modeling method.

본 연구에서는 대형 지반구조물의 축조재료로 이용되는 대입경 조립재료의 동적 변형특성을 평가하기 위한 목적으로 국내 최대 규모의 대형 공진주시험시스템을 구축하였으며 그 성능 및 적용성을 검증하였다. 신규 시험기는 하단 고정, 상부 자유단에 코일-자석 시스템에 의한 가진 하중을 제어하는 전형적인 Stokoe 식 공진주시험 장치이며, 지름 200 ㎜, 높이 400 ㎜의 원주형 공시체에 대한 시험이 가능다. 시험기의 구동 및 계측 시스템은 굵은 자갈 이상의 조립재료에 대한 활용에 적합하도록 출력 및 정밀도를 확보하였으며, 고정밀의 제어 계측이 기능한 자동화 시스템으로 구성되었다. 공진주시험기의 동적응답특성 및 사용성을 검증하기 위한 방안으로 금속시편과 다수의 폴리우레탄 검증 시편을 이용하여 시험을 수행하였으며 타 시험기 또는 시험기법과의 비교를 통하여 정밀도를 평가하였다. 대형 시험기의 지반재료의 동적 변형특성 평가에 대한 신뢰성을 확인하기 위하여 동일한 사질토 시료에 대한 시험을 일반 공진주시험과 병행한 결과 공시체의 크기에 따른 효과가 일부 나타나지만 전반적으로 동일한 결괴를 획득하였다. 최종적으로 댐 축조용 사력재료 시료에 대한 대형 공진주시험을 수행하였으며, 그 결과의 실효성을 확인하였다. In this study, a resonant column testing system which is the largest in Korea has been developed to evaluate the dynamic deformation characteristics of coarse granular geomaterials, and the performance and the applicability of the testing system have been verified. The system has been developed as a typical Stokoe type device whose boundary conditions are fixed bottom and free top with additional mass, and can adopt a large specimen with 200 ㎜ in diameter and 400 ㎜ in height. The driving and measurement instruments are configured as high performance and precision systems, hence the automated testing system is appropriate to drive enough stress and to measure the behavior precisely for the test in practical manner. The dynamic response of the mechanical components and the applicability of the system have been evaluated using metal specimens as well as polyurethane specimens, and its precision was verified by comparing its results with those from other equipment and/or methods. To confirm the applicability of the large system for coarse geomaterials, the resonant column test results from both large and normal scale apparatus for the same material were compared and it was found that the result can be partially affected by scale. Finally, the dynamic deformation characteristics of coarse geomaterial which is used for construction of large dam was evaluated using the large system and its practicality could be confirmed.

Recently much attention has been paid to urban slums and deteriorated residential environment due to vacant/abandoned houses in medium-and- small cities in Korea. Since 1989, the Korean Government has established and implemented some special urban policies particularly in order to improve residential environment for low-income peoples as well as weak and old peoples. However, most polices have been focused on physical improvement of the deteriorated residential areas in metropolitan cities without considering the social environment of residential communities in small cities. This s tudy a ims to analyze the characteristics of residential environment improvement and to suggest some strategic alternatives for renewal of residential areas in terms of economic and social/welfare regeneration considering residents income and welfare. For this study, a medium-and-small city, Jinju in Gyeongnam Province, has been chosen and 18 districts have been selected for residential environment improvement in city center and inner city. The sites survey has been implemented to explore the physical characteristics of residential areas from 1991 to 2006. In addition, a questionnaire survey has been investigated focusing on potential characteristics to improve the efficiency. Finally, we suggest diverse planning and regeneration techniques and policies based on physical and social/welfare improvement with resident participation in deteriorated areas.

국내 저수지 축조 재료특성 분류를 위한 실험적 연구

김우용(Kim Woo Yong),김남룡(Kim Nam Ryong),임정열(Lim Jeong Yeul) 한국방재학회 2017 한국방재학회논문집 Vol.17 No.2

최근 기후변화에 따라 발생 빈도가 높아진 태풍과 국지성 호우 등의 기상이변은 다양한 자연재해의 원인이고, 특히 저수지의 붕괴는 심각한 인명피해 및 재산피해를 일으킨다. 국내 70% 이상의 농업용 저수지는 1945년 이전에 축조되어 노후화가 진행 중이며, 제체의 열화, 방류능력 부족 등으로 심각한 재해 위험성을 내재하고 있다. 이러한 위험요인에 따른 저수지의 위험도를 평가하기 위해서는 축조 당시의 설계자료, 시공기준, 재료물성 등의 기초정보가 필수적이다. 그러나, 현재 국내 대다수의 노후 저수지는 기본 자료 또는 기준이 없어 축조 특성을 고려한 평가가 어려운 실정이다. 따라서, 본 연구에서는 저수지의 지반공학적 위험도 분석시 요구되는 물성값의 확보를 위하여 국내 저수지의 10개소에 대한 축조재료 특성을 조사ㆍ분석하고, 댐 설계 기준과 비교하여 저수지 위험도 분석 및 평가를 위한 입력변수로 활용할 수 있는 대표물성 값을 분류ㆍ제안하고자 한다. 본 연구성과는 지반공학적 물성 정보가 불충분한 저수지의 위험도 평가에 활용하여 위험도 범위를 보수적으로 산정하는데 효과적일 것으로 판단된다. Extreme rainfall events by typhoon or monsoon, which are more critical by recent climate change, induce various natural disasters. Damages or breaches in rural reservoirs may cause lots of economic loss and casualties. Currently more than 70 percent of rural reservoirs in Korea have been built before 1945, and the embankments have serious hazard risks such as aging and/or structural deteriorations, insufficient discharge capacity, etc. Geotechnical information of the reservoirs such as geometric design, material properties, construction conditions are mandatory for safety assessment and evaluation. Especially, geotechnical risk assessment of reservoir is not applicable where material properties are not sufficient. The objective of this study is to analyze the characteristic of construction materials of reservoirs, and propose the representative parameter for the analysis and estimation of the risk analysis. This result could be effective to estimate the risk conservatively for small dam.
