This article aims to explain how Gangnam, as a model and standard of compressed urbanization in South Korea, was created. Gangnam and Gangnam-style urbanization need attention not only because they contrast with Korea's urbanization in the past as well as urbanization in the West but also they provide an important model in contemporary Korea's politics, economy and culture. However, there are little studies of how Gangnam's peculiar urbanism was created. To fill this gap, this article will first capture Gangnam's peculiar urbanism as a material landscape and sociocultural lifestyle. Gangnam-style urbanism is (a) materially characterized by high-rise apartment complexes owned by the middle and upper class for dwelling and asset growth and (b) socio-culturally characterized by political conservatism, public indifference, competition over academic performance, appearance, and fashion, and nightlife. Then it will show Gangnam's archetype was created in a spatially and temporally compressed way in and through the spatial selectivity of Korean anti-communist authoritarian developmental state strategies: (1) anti-communism led to the diffusion and accommodation of the population through apartments in Gangnam in the context of its confrontation with North Korea and the fast-growing population of Seoul; (2) military authoritarianism excluded the low-income class and the urban poor from urban development; and (3) the developmental state adopted selective housing policy which treated construction companies and the middle class preferentially through exceptional zoning and price distortions, promoting the construction of apartment in Gangnam and its resultant uneven development.

This research examines the impacts of urban population growth on per capita $CO_2$ emissions with particular focus on the interaction effect between urbanization and income levels. Employing the Panel Fixed Effects model together with the Pooled LS and Panel GLS models, the research reported here analyzes the relevant data on 84 countries. The statistical results show a nonlinear(an inverted-U) relationship between urbanization and per capita $CO_2$ emissions; that is, while the urban agglomeration leads to increases in per capita $CO_2$ emissions for low income countries, this adverse impact does not hold true for high income countries. The research findings can contribute to addressing broad issues of urban compactness and patterns of energy consumption that should be considered by those concerned about the sustainable urban development.

우리나라는 높은 인구밀도, 도시화, 급속한 산업화 등 환경관리에 매우 불리한 여건에 놓여 있다. 1 9 7 0년대 이후의 고도 압축성장과정에서 복합적인 환경문제가 동시다발적으로 발생하였고, 최근에는 신기술 개발에 따른 새로운 환경위해물질에 의한 인체 및 생태계의 피해 발생 가능성이 증대되고 있다. 한편 환경문제 해결과정에서는 지역간, 이해집단간의 갈등이 첨예하게 대립하고 많은 환경문제가 국제적인 협력과 공동대응이 요구될 만큼 복잡하게 전개되고 있으며, 국민적 욕구와 기대수준은 단순한 환경질의 개선뿐만 아니라 경제·사회·환경이 조화를 이루는 지속가능한 발전의 실현과 삶의 질 향상을 요구하고 있다.(중략)

The compact city usually provides good accessibility of residents with multiple transportation modes. However, in a compact city, annual average of travel distance per household by car is relatively short due to more congested traffic condition and larger travel cost than disperse city. As a result, total travel demand is decreasing when the region becomes more compact. Therefore compact development is regarded as one of the sustainable choices for future urban planning in many countries. This study aims at an empirical analysis of the relationship between urban compactness and travel demand based upon land-use and travel data for city of Seoul. In this study, 424 sub-districts with the mixed land-use patterns are assessed in a hexagonal diagram. The measurement is based on the relative deviation of each sector's characteristics including numbers of residence, manufacture, and trade & service. Multiple linear regression models are developed to analyze the effects of urban compactness on zonal trip generations. As a result, the trip generation rate in the residence-intensive and mixed-use areas is found to be relatively low. Furthermore, residents in high-compact areas tend to use public transport more often than residents in less compact areas.

Urban cmmunity films have achieved the industrial modern society's idiosyncrasy Popular films have achieved the industrial growth through city as the completion of modernization. They also have represented the social meaning of urban space, and have expanded 'their political space' This filmic challenge showed diverse negative factors which were the poor's economical difficulties, the relative robbery of their education and job, and adhered class in city through developing the urban space with were hidden beyond modernity's splendor.

지난 몇 십 년간 한국사회는 급격한 도시화와 시-공간 압축을 겪었다. 이러한 변화는 한편으로는 정체성 혼란을 심화시켰으며, 다른 한편으로는 여가시간의 증대를 초래하고 있다. 이 정체성 혼돈과 여가의 증대 경향이 대중들로 하여금 ‘삶의 질’요구를 제기하게 하였다. 이 논문에서는‘삶의 질’향상이 자연과 장소에 대한 문화적 감수성 회복을 통하여 이루어질수 있다고 주장한다. 여기서 문화적 감수성이란 자연과 장소에 대한 심미를 의미한다. 16세기의 위대한 유학자 퇴계 이황의 경관독해처럼, 유교적 자연미는 숭고미가 아니라 자연합일 감성이다. 유학자들은 이러한 자연에 자신을 합일(정체화)하는 감성을 가지는 것을 최선의 일상적 실천으로 삼았다. 생생불식하는 자연의 모습을 ‘천지의 마음’으로 보고, 그것을 체득하는 것에 자기수양의 궁극적 목적을 두었기 때문이다. 퇴계는 자연합일이 아니라 거주 과정에서 형성된 인간-자연 간이 감성적 연계에 관한 것이다. ‘삶의 질’추구는 인간과 자연생태계 간의 심각한 단절을 극복하기 위한 참된 거주경험에 대한 욕구이다. 우리는 유학자의 ‘자연합일’감성으로부터 진정한 거주경험을 배울 수 있다.

As urbanization progressed along with quantitative expansion of the construction industry, concrete has developed diversely as a material that is the most extensively used in the construction industry. However, aggregate resources that are an essential element of concrete production are gradually being depleted and the phenomenon of aggregate shortage has been intensifying due to the reinforcement of regulations on environmental issues. Therefore, in the present study, environment friendly mortar was made by replacing aggregate with mud that is dumped when dredging sand is dumped. To identify the dynamic characteristics of the mortar and to identify its fire resistance efficiency, the mortar was heated and its residual compressive strength was measured. In the results, the residual compressive strength values of MM1, MM2, and MM3 were 45%, 95%, and 57.7% respectively and the mix MM2 showed the highest fire resistance efficiency.

최근 홍수의 특성과 피해 양상은 과거와는 다르게 변화하고 있으며, 급격한 도시화로 인하여 기존 하천유역의 저류 능력이 감소하였는데 이러한 한계를 극복하기 위하여 이미 외국에서는 대심도 터널을 활용한 홍수재해 관리방안이 오래전부터 활용되어 왔다. 본 연구에서는 현재 서울시에 건설중인 '신월 빗물저류배수시설' 연속강우 시 대심도 터널의 수리적 안정성 평가와 운영방안 수립을 위한 수리모형실험을 실시하였다. 모형은 Froude 상사법칙을 사용하여 원형의 1/50크기로 제작하였다. 모형의 전체 저류 가능량은 모형기준 $2.78m^3$ (원형 $347,778m^3$)이며, 터널 내 잔류수는 전체 저류 가능량의 0 ~ 100%까지 10%씩 변화시켜 실험 CASE를 선정하였다. 각 실험CASE별 수직 유입구 안정성 평가를 실시한 결과 터널 내 잔류수가 10%~80%까지 존재 할 때는 저지수직구1에서의 압축공기 폭발현상으로 인한 월류현상이 발생하였으며, 10%~40%까지는 저지수직구2에서 월류현상이 발생하였다. 하지만 고지수직구에서는 모든 CASE에서의 공기폭발 현상 및 월류현상이 발생하지 않아 유입성능 및 공기배출 성능이 충분히 발휘되고 있는 것으로 분석되었다. 또한 저지수직구1에서의 월류현상 발생 시점은 5분55초에서 3분42초까지 빨라졌으며 저지수직구2에서의 월류현상 발생 시점은 5분57초에서 4분57초로 빨라졌다. 이는 터널 내 잔류수량이 증가할수록 터널 내 만관시점이 빨라져 발생하며, 저지수직구1,2에서의 압축공기 폭발현상 및 월류 현상은 터널 내에서 발생한 반사파의 영향으로 판단된다. 차후 터널 내 반사파 발생에 대한 연구가 추가적으로 진행되어야 할 것이다.

Urban flooding due to rapid urbanization has recently become frequent. In this study, a hydraulic model experiment was conducted on Shinwol rainwater storage and drainage system constructed for the first time in South Korea to prevent urban flooding. Experiments were preformed for 55 scenarios, of which 19 overflows occurred. In addition, the video analysis for the scenarios where the overflow occurred showd that the overflow occurred during the process of exhausting the pressurized air in the facility and the undular bore were moving. Results of this study, it was judge that it would be advantageous to maintain a completely drained or full-pipe condition for stable operation of the Shinwol rainwater storage and drainage system for continuous rainfall in the future. And it is necessary to additional research on the correlation for the magnitude of inflow discharge, overflow and undular bore.

Addressing urban noise problems, this study develops eco-friendly, inorganic sound-absorbing panels, overcoming the limitations of traditional PMMA and cement-based panels. These conventional panels pose safety risks due to flammability and environmental concerns due to carbon emissions. Utilizing industrial waste, the research comprises two phases: initial tests for physical and performance characteristics (fluidity, density, compressive strength, sound absorption) and subsequent development of optimized panel mixtures. This approach aims to replace existing panels with sustainable, effective alternatives, significantly contributing to safer, environmentally responsible urban infrastructure. The findings of this study have implications for the sound panel market, offering novel solutions for noise control while aligning with environmental and safety standards.
