Crime prevention through environmental design (CPTED) has become a popular urban planning approach to preventing crime and mitigating fear of crime through the improvement of physical neighborhood environments. CPTED is widely used to improve deteriorated neighborhoods that suffer from crime. However, few studies have empirically examined the complex relationships among CPTED, fear of crime, and active living. Our study, therefore, investigated the effects of CPTED measures on walking frequency

In the early 2000s, nearly 30% of South Korean cities reportedly shrunk in terms of population, number of enterprises, and property disinvestment. Although many researchers have already documented socioeconomic changes linked with shrinking cities, little is known about how changes in a neighborhood’s built environment influence the process of shrinking within a city’s local context. Here, a neighborhood called Songhyun-dong in Incheon, which was previously one of the busiest mixed-use retail ne

Neighborhood revitalization projects have been implemented to improve both the physical and social environments of deteriorated communities. The purpose of this study was to evaluate the impacts of government-sponsored community building projects (CBPs) in Seoul, Korea, that aim to revitalize declined communities through resident participation on the social capital of their inhabitants. The present study compared survey data collected from 12 completed CBPs and matched communities of similar siz

Bright Internet research was launched as a core project of the AIS Bright ICT Initiative, which aims to build an ICT-enabled Bright Society. To facilitate research on the Bright Internet, we explicitly define the goals and principles of the Bright Internet, and review the evolution of its principles. The three goals of the Bright Internet are: the realization of preventive security, the provision of the freedom of anonymous expression for innocent netizens, and protection from the risk of privac

In Seoul, most of the new private buildings were mandated renewable energy installations more than 12% of total energy use in 2015. There are solar power, solar heat, geothermal, sunlight collecting, fuel cell, and small cogeneration systems in applicable renewable energy. Accordingly, some reconstruction apartments want to apply geothermal heat pump systems as heating and cooling. This has resulted in reducing the demand for district heating since district heating had been supplied in these are

Rapid urbanization and the increased use of private vehicles have led to many urban problems. Transit-oriented development (TOD) has been proposed as a solution to these problems. The present study examined the relationship between meso-scale urban form and bus ridership, as well as the link between bus and subway use in Seoul, Republic of Korea. Spatial regression models identified the effects of TOD planning factors on bus ridership at 2300 target bus stops in Seoul. The analysis revealed that

This article examines the relationship between cultural differences and the nonexpert evaluations of architectural design creativity. In study I, Caucasian Americans (N = 126) and East Asians (N = 137), who did not major in architecture and urban design, evaluated the novelty and appropriateness of 5 unusual architectural shapes, selected by 5 experts in the field of architecture. In study II, the 2 cultural groups selected preferred alternatives from 3 pairs of silhouettes of architectural shap

As urbanization has matured in many areas, interest in qualitative values such as residents' residential satisfaction, social capital, and subjective well-being (SWB) has increased. However, few studies have investigated the influence of different urban environments, including housing types, on residential satisfaction, social capital, and SWB. The present study compares residential satisfaction, social capital, and SWB levels of two different housing types: high-rise apartments and low-rise dwe

South Korea’s Innovation City policy aims to balance the geography of economic activity across the country by relocating public institutions to local cities. The economic impact of relocating public institutions to local cities has been assessed by examining job creation, public spending, the quality of public services or demands for housing and employment in donor cities. However, as economies have become increasingly knowledge-based, the attractiveness of urban areas to young workers has becom

Urban agriculture has become a favored activity in many cities around the world. This study explores how urban agriculture’s potential can be maximized in Seoul, South Korea, a city characterized by high-density residential complexes. It selects six existing residential complexes with representative site typologies and diverse density levels. The study’s aim is to assess the impact of various typology and density settings on percentages of ground-level surface with direct sunlight above certain
