Design and construction professionals are entrusted to design built environments that can assure public safety. Crime statistics is one indicator that reflects the correlation between built environments and public safety. Acknowledging the perception of pedestrians, specifically their psychological and emotional reactions toward certain public space settings would be another effective parameter to develop a good foundation to create more livable and safer neighborhoods. With these in mind, the a

Planning scholars and practitioners know that planning projects and research are more likely to achieve significant outcomes when the problem is addressed at the most appropriate level of neighborhood. Selecting the right scale of neighborhood, however, is always challenging. To create conceptual framework for the choice of an appropriate neighborhood unit in future studies and projects, this article attempts to reveal a hierarchy of neighborhood and key elements for different levels of neighbor

With the continuously increasing demand for air travel, competition among airlines has increased as well. The purpose of this study is to examine empirically the causal relationships among the perceived service quality, corporate image, customer trust, and corporate reputation of Asiana Airline in South Korea using SERVQUAL measures. An onsite survey of Korean passengers was conducted. The results of this study reveal that responsiveness and reliability of service quality significantly affect co

This research examines the mismatch between the reality of a city’s population loss and the planning strategies they have adopted. Thirty-five depopulating U.S. cities’ comprehensive plans are analyzed to determine whether they are acknowledging past depopulation trends, how they are projecting future population changes, and what planning strategies they are pursuing in light of their depopulation trends. Findings illustrate a majority of cities acknowledge depopulation; however, they rely on op

The principles of New Urbanism such as increased density, mixed land uses, and street connectivity are often recommended in response to the typical conditions of suburban developments. Much current empirical research has begun to test whether these principles can increase property values. The findings of these studies have, however, been quite inconsistent. This research attempts to quantitatively synthesize these conflicting findings through a statistical meta-analysis. This study finds that a

Abstract Planning interventions have been applied to improve the well‐being, hereafter happiness, of residents. The happiness in shrinking cities, in particular, becomes more critical since urban decline tends to induce an unequal and uneven distribution of care under a limited budget and human resources. Using geo‐tagged Twitter, census, and geospatial data on Detroit, Michigan, which is one of the well‐known shrinking cities in the U.S., the spatial distribution of sentiments, topics of tweets

The active compounds of medicinal plants vary in composition and content depending on environmental factors, such as light, temperature, and soil. According to the Korean Pharmacopoeia standards for herbal medicine, the sum of nodakenin, decursin, and decursinolangelate, which are the marker components of Korean Angelica, should be at least 6.0 g/100 g. However, the content of the components in Korean Angelica cultivated in South Korea often fall below 6.0 g/100 g, due to weather conditions and

Abstract Due to the growing importance of accessibility to urban amenities on quality of life and neighborhood satisfaction in South Korea, various efforts have been made to improve accessibility to urban amenities by establishing a minimum standard, an approach called Living Social Overhead Capital (Living SOC); for example, one such standards states that an elementary school should be reachable within a 15-min walk. However, these endeavors have not yet resulted in an equal distribution of Liv

This research examined social media’s role in understanding perceptions about the spaces in which individuals interact, what planners can learn from social media data, and how to use social media to inform urban regeneration efforts. Using Twitter data from 2010 to 2018 recorded in one U.S. shrinking city, Detroit, Michigan, this paper longitudinally investigated topics that people discuss, their emotions, and neighborhood conditions associated with these topics and sentiments. Findings demonstr

This research seeks a comprehensive process for developing a design guide utilizing pattern language and social network analysis. Pattern language is a structured mechanism for describing good design practices, the patterns. Network analysis helps analyze quantitatively the relationships between the patterns and identify the relative importance of each pattern. The result is also visually delineated as a web of networks to illustrate how these patterns are clustered and connected. In this study,
