BACKGROUND A retrospective study involving 502 lung cancer patients who had received pulmonary resection from 2009-2013 was conducted in order to compare the clinical characteristics of patients whose diagnosis was detected by low-dose computed tomography (LDCT) and computed radiography (CR). METHODS Two groups were established, based on the method of detection: the LDCT group included 172 lu...

from the past to the present time, in all civilizations and countries, urbanization is considered the most striking evolution of human societies. with the advent of the industrial revolution and the rapid expansion of cities, societies were faced with numerous problems. one of the most significant problems is extreme centralization in one city or more and fragmentation of urban hierarchical sys...

Peri-urban areas are typically associated with high growth regions that have witnessed rapid landscape changes on the peripheries of metropolitan and urban areas with a particular focus on high amenity areas. These former rural lands adjacent to the edges of urban areas into which they would typically expands or influences have been described as peri-urban areas (‘peri’: around, about or beyond...

Currently most optimization methods for urban transport networks (i) are suited for networks with simplified dynamics that are far from real-sized networks or (ii) apply decentralized control, which is not appropriate for heterogeneously loaded networks or (iii) investigate good-quality solutions through micro-simulation models and scenario analysis, which make the problem intractable in real t...

The Philippines is 52% urbanized (ADB figure, the UN estimate is 59%), this percentage is expected to increase to 60% in 2010. The urban population grew very rapidly at an annual rate of close to 5% from 1960 to 1995, but has since slowed to approximately 3% annually. Given relatively slow economic development over the last three decades (relative to East Asian norms), the level of urbanization...

Options for a New Rural America, revealed important insights into the theoretical foundation for analyzing rural economic issues (Barca) and provided focus for new public policies for rural and urban regions (Stauber, Rosenfeld). Indeed, viable regions, by necessity, contain both rural and urban areas; else the “region” is conceived too narrowly. My comments will focus attention on several of t...
