This study investigates the impacts of urban land-use fraction and temperature advection on the urban heat island intensity over the Seoul metropolitan area using the UM (Unified Model) with the MORUSES (Met Office Reading Urban Surface Exchange Scheme) during the heat wave over the region from 2 to 8, August 2016. Two simulations are performed with two different land-use type, the urban (urban simulation) and the urban surfaces replaced with grass (rural simulation), in order to calculate the urban heat island intensity defined as the 1.5-m temperature difference between the urban and the rural simulations. The land-use type for the urban simulation is obtained from Korea Ministry of Environment (2007) land-use data after it is converted into the types used in the UM. It is found that the urban heat island intensity over high urban-fraction regions in the metropolitan area is as large as 1℃ in daytime and 3.2℃ in nighttime, i.e., the effects of urban heat island is much larger for night than day. It is also found that the magnitude of urban heat island intensity increases linearly with urban land-use fraction. Spatially, the estimated the urban heat island intensities are systematically larger in the downwind regions of the metropolitan area than in the upwind area due to the effects of temperature advection. Results of this study indicate that urban surface fraction in the city area and temperature advection play a key role in determining the spatial distribution and magnitude of urban heat island intensity.

For the purpose, this study examines to identify factors influencing urban to rrual migration for farming. This study analyzed 217 urban to rural migrant farmers. The result of this study were as follows: the influence of the main variables on the agricultural challenges of the urban to rural migrant farmers were observed as the relationship of the level of financial preparations, the motivations of urban to rural migration, the agricultural income, the annual of urban to rural migration, the size of agricultural, gender, and age. This study result show that urban to rural migrant farmers' agricultural challenges is influenced by almost economical factors. Therefore, for the successful agricultural activities of the urban to rural migrant farmers show significant impact to need on the composite effort of all such as the individual, the family, the rural society, local autonomous entity, the government.

Since the mid-1990s, Korea has recorded low population growth rate. Based on the figures provided by the Statistical Korea, Korea may be even confronted with decreasing trends in the total population at the end of 2010s. In addition, Korea may experience the hyper-aged society in the mid-2020s. In the depopulation era, we have to devise alternative urban management policies reflecting low and reversed trends in the urban population. It is almost certain that urban policy-makers have to deal with a new series of urban problems, even jeopardizing the continuity of urban territories. In order to minimize the negative impact derived from depopulated phenomena, they have to develop sound and sustainable urban policy alternatives. This research adopts system dynamics approaches, revealing key factors exerting significant impact on the existing urban management policies. In specific, it pays attention to major causal loops, reinforcing or balancing behavioral.

Reliable predictions of the movement of earth retaining structures and the ground adjacent to braced walls in urban excavation are often difficult due to many variable factors. The ground settlement and the damage of adjacent structures in urban excavation has been an important issue. Therefore, the stability of the adjacent structures must be secured with the excavation support and research on the protection of adjacent structure is necessary. This study showed an urban excavation case and introduce observation method for case of damage behavior in urban excavation.

This study was carried out to examine the feasibility of urban landscape development plan that can accomodate urban agricultural lands and go well with urban environments. Effective development and utilization methods of urban agricultural lands as a part of urban landscape were studied through the analysis of public functions of urban agricultural lands by using GIS.

The urban wetland park is an indispensable part of an ecological city. It has aroused widespread attention and even quickly planning and construction around the country. But, in terms of the nature of the urban wetland park, there is a contradiction between the protection of urban wetland resources and the openness of the urban park for public. This article starts with the necessity for construction of urban wetland park, more over expound the existent problems between the protection and openness of the urban wetland park and to propose appropriate measures through the case study on Nanhu National Urban Wetland Park, Tangshan.

This paper reviews the literature on urban sustainability with the objective of drawing more attention to the social aspect of sustainability in urban planning. Given that social capital is a crucial component of moving towards more progressive smart cities and urban innovation, it is important to investigate the social dimension of sustainability and the opportunities that just cities can bring to improve the quality of life for urban dwellers. This paper is divided into three sections. The initial section provides an introduction to urban sustainability, discussing the historical roots of sustainability and sustainable development ideas, the three fundamental elements of sustainability, and the process of defining and measuring sustainability in an urban setting. Moving on to the second section, it delves into the body of work related to linking urban sustainability with urban strategies. The third section finally addresses the emergence of literature on just sustainability and just cities, which can give valuable insights to city policymakers who are trying to improve balanced sustainability.

Nowadays, as a result of increasing income and spare time, the social demands for better living environment become more increasing. Above all, landscape improvement, the essential part of physical environment, will be a more important subject in urban planning. In these circumstances, classification of urban scenic quality is required for urban landscape development programs. The major purpose of this study is to suggest a technical method of designing urban scenic quality map for urban district area based on the scenery management system of the USDA forest service and literature studies. As a conclusion of this study, four steps are desirable for the technical method for designing a scenic quality map of urban districts areas : 1) Define a landscape unit on the map, 2) Take a photograph of these landscape unit on site, 3) Evaluate the landscape unit by semantic differential scale with landscape adjectives, and 4) Draw the scenic quality map, investigate the landscape characteristics and suggest the landscape scenic development plans.

낙후된 도시 주거지 재생의 방안에 대한 논의와 연구가 활발하게 진행되고 있다. 그러나 도시농업을 단순히 주민참여의 수단이나 일차산업으로서의 가치에 대한 논의가 부분적으로 이루어지고 있는 실정이다. 기존의 공간자본가치 극대화의 수단으로 전락한 도시개발의 새로운 극복방안으로 장소자본 가치를 높일 수 있는 대안이 모색되어야 할 시점이다. 따라서 본 연구는 창조적 산업융합개념을 적용한 도시농업의 장소적 가치를 논의함으로써 지속가능한 도시재생의 단초를 이론적 바탕을 제공하는 것이 목적이다. 이를 위하여 기존의 도시개발 방식의 문제점, 산업융합과 도시농업의 의미, 그리고 산업융합형 도시농업의 장소가치에 대한 이론적 연구를 통해 도시재생의 새로운 패러다임을 제시하고 있다.

The landslide disaster damage has been increased by mountain development, leading to construction of educational facilities, medical facilities, petty industrial facilities, and large housing complexes. Therefore, effective regulation is required as an effort in urban planning solutions. For suggesting specific mitigation strategies on urban landslide, this study aims to define evaluation criteria for urban planning management of debris-flow disaster. AHP (Analytic Hierarchy Process), one of the multiple criterion decision making methods, was utilized in this study. This study makes use of 16 sub-criteria under the framework of hazard, exposure, and vulnerability, and well-planned expert survey measures their weights. The weights are also applied to evaluate each grid in urban space (min $10{\times}10m$) and classify it with red, orange, yellow, or green grade so that areas at higher risk are clearly identified. This study concludes that the suggested method is useful to support a strategies for urban planning management of debris-flow disaster, particularly in a GIS base.
