Cheongna City Tower is a 448-meter-high rise observatory tower with 8.7:1 aspect ratio located at central lake park in Incheon Cheongna international city. The tower is a crystal shaped image and it turns invisible when the façade is activated. The tower was planned to be hexagonal 30-story building with two basements which are composed of mega frame structure using mega column and mega brace. In order to minimize the wind effect, the blow-through area was installed so that the wind can pass through. This observatory tower is an unprecedented project since the whole building is covered by façade for invisibility effect.

A mega sport event as the globalization phenomenon is not only the symbol of the process of modernization but also the vehicle to upgrade global power and hold a dominant position in the world competition under the post-industrial era. This study notifies the role of mega sport events as a strategy for urban innovation in the context of global and local. Comparing the different roles of mega sport events between developing countries and developed countries, we intend to answer two questions: 1) what explains the nature and role of mega sport event, and 2) what are the major evidences of the transition in the globalization era. The conceptual framework, based on the temporal and spatial perspective, provides the mechanism through which the strategy for urban innovation has been changed from 'motivation for modernization' to 'rethinking of localization.' Focusing on the case of Seoul, we also compare major issues between two phases: role of agent, urban form, and urban development. Finally, this study sheds light on the concept of 'glocalization' which means the convergence of globalization and localization; and suggests the roles of (local) agent for hosting mega sport events.

Designed by star architect of Moshes Safdie, Raffles City Chongqing includes a total of 6 mega high-rise towers 250 to 380 m tall, a sky conservatory, a 5-storey high shopping mall and a 3-storey basement car parking. Located at the confluence of the Yangtze and Jailing Rivers, the site for the project is imbued with a significance that is immediately symbolic, both as a sign of Chongqing's important past and as a vivid indicator of the city's thriving present and future. The design for the project to be situated at this gateway takes as its governing idea the image of powerful sails upon the water. The outer facades of the project's eight towers - the transparent surfaces that will face the water to the north - are meant to recall a fleet of ancient Chinese ships, with their huge rectangles of white canvas filled by the wind. This is a $1.13million\;m^2$ mega scale integrated project of office, retail, hotel, service residence and high-end residence with the transportation hub and traffic circulation at various levels of the project. This paper presents the multi-dimensional hybrid design, engineering and construction of this mega scale project. The innovations and the cutting-edge technology used in this project are introduced and discussed benchmarking the design and construction of the skyscraper cluster in a major city like Chongqing of China.

Yangon Mega City is densely populated and most urbanization area of Myanmar. Rapid urbanization is the main causes of Land Use and Land Cover (LULC) change and they impact on Land Surface Temperature (LST). The objectives of this study were to investigate on the LST with respect to LULC of Yangon Mega City. For this research, Landsat satellite images of 1996, 2006 and 2014 of Yangon Area were used. Supervised classification with the region of interest and calculated change detection. Ground check points used 348 points for accuracy assessment. The overall accuracy indicated 89.94 percent. The result of this paper, the vegetation area decreased from $1061.08sq\;km^2$ (24.5%) in 1996 to $483.53sq\;km^2$ (11.2%) in 2014 and built up area clearly increased from $485.33sq\;km^2$ (11.2%) in 1996 to $1435.72sq\;km^2$ (33.1%) in 2014. Although the land surface temperature was higher in built up area and bare land, lower value in cultivated land, vegetation and water area. The results of the image processing pointed out that land surface temperature increased from $23^{\circ}C$, $26^{\circ}C$ and $27^{\circ}C$ to $36^{\circ}C$, $42^{\circ}C$ and $43.3^{\circ}C$ for three periods. The findings of this paper revealed a notable changes of land use and land cover and land surface temperature for the future heat management of sustainable urban planning for Yangon Mega city. The relationship of regression experienced between LULC and LST can be found gradually stronger from 0.8323 in 1996, 0.8929 in 2006 and 0.9424 in 2014 respectively.

다양한 시설의 건설, 다수 이해관계자의 참여, 긴 사업기간 등의 복잡성으로 인해 대규모 건설프로젝트는 이를 관리함에 있어 어려움이 있다. 효과적인 대규모 프로젝트관리를 위해서는 합리적인 진도율 측정이 중요하고, 이를 위한 다양한 방법들이 제안되었다. 하지만 기존의 방법들은 단일 또는 일부 시설의 건설 프로젝트로 한정하였기 때문에 다양한 시설들을 건설하는 대규모 프로젝트에 적용하는 데 한계가 있다. 따라서 본 연구는 대규모 건설프로젝트의 특성을 반영한 진도율 측정 프레임워크를 제안함을 목표로 한다. 프레임워크는 작업분류체계 개발, 주요시설별과 하위시설별 가중치 산정, 통합 진도율 산정으로 총 4가지 단계로 이루어져 있다. 본 프레임워크를 검증하기 위해서 세종시를 대상으로 사례연구를 수행하였고, 활용 가능성을 검증할 수 있었다. 본 연구를 바탕으로 대규모 건설프로젝트의 진도율을 보다 합리적으로 측정할 수 있고 효과적인 프로젝트관리가 이루어질 것으로 기대된다.

The water shortage in mega cities in Asia, which face a rapid growth in urban population, is an outstanding problem. It is important, therefore, to accurately estimate the water balance in each city in order to use the limited water resources effectively. In this study, we estimated the potential water resources in し sixteen mega cities in Asia. The target cities were Delhi and Calcutta, India; Colombo, Sri Lanka; Dhaka, Bangladesh; Yangon, Myanmar; Bangkok, Thailand; Kuala Lumpur, Malaysia; Singapore; Jakarta, Indonesia; Hanoi, Vietnam; Beijing and Hong Kong, the People's Republic of China; Seoul, the People's Republic of Korea; Manila, the Philippines, and Sapporo and Tokyo, Japan. The potential water resources were estimated by subtracting the actual evaporation from the amount of rainfall. The actual evaporation was estimated using the potential evaporation obtained by Hamon's equation which requires the air temperature and the possible hours of sunshine. When the results of Hamon's and Penman's evaporation equations were compared, a considerable error appeared in the low latitude region. The estimation using Hamon's equation was corrected with the linear regression line of Hamon's and Penman's equations. A classification of the land cover was carried out based on satellite photographs of the target cities, and the volume of surface runoff for each city was obtained using the runoff ratios which depended on the land cover. As a result, the potential water resources in the above mega cities in Asia were found to be greater than the world average. However, the actual water resources which are available for one person to use are probably very limited.

이 논문은 유럽 교과서에 기술된 '서울'을 분석하여 오늘날 서울이 유럽 교과서에 어떻게 투영되어 있는지 살펴보는 것이 목적이다. 이 연구에서는 유럽 주요국인 영국, 프랑스, 스페인, 이탈리아, 독일 교과서에 기술된 '서울'이 어떤 방식으로 서술되고 있는지 서술경향을 살펴본다. 유럽 교과서에서 서울은 거대도시 중의 하나로 도시문제를 가지고 있는 공간이며 경제중심지로서 다른 대도시들 간의 상호 교류를 담당하고 있는 도시로 소개된다. 이와 함께 서울은 다른 대도시들과 비교했을 때 상대적으로 경쟁력이 낮은 도시로 평가받고 있으며 서울이 보유한 역사 및 문화 자원에 대해서는 주목받고 있지 않다. 그러나 여기서 살펴본 유럽 교과서 중 서울 관련 서술에서 오류가 극히 드물다는 점은 긍정적이다. 앞으로 교과서 서술에서 한국의 경제적 측면뿐만 아니라 역사 및 문화에 대한 서술이 증대되어 교과서가 한국을 알릴 수 있는 신뢰할 수 있는 콘텐츠가 되기를 기대한다.

Daily living area can be delimited differently depending on what area is to be focused. Based on regional interaction, the present study empirically analyzed the difference between living areas focusing on rural area and ones relying on urban area. We established two types of living areas in Busan-Ulsan mega city with different focus areas (rural versus urban), using travel OD data (2006). According to the result, the fonn of spatial clusters in urban living area differed from that of spatial clusters in rural area; the boundaries of living area were not fit to those of administrative areas in both types; and living areas in both types tended to extend over more than two administrative areas. The results cast some implications concerning spatial planning and policy for living area delimitation. First, since the spatial structure and interconnection of urban area differs to those of rural area, it is required to delimit living areas discriminatively depending on the objectives of the spatial plan. Additionally, the living area should be established more specifically and systematically by further subdividing the form of spaces depending on the objectives and types of the plan. Second, the administrative areas should be consolidated now that the difference of boundaries of administrative and living areas lead to inconvenience of residents, increased administration costs and scale diseconomy. Lastly, the living areas should be delimited by the metropolitan or mega city planning and thus be reflected to its offsprings.
