AbstractIncreasing concern for climate change adaptation and disaster risk reduction is driving the need for more accurate and sophisticated tools of analysis to protect populations. Standards of analysis that can normalize measurements under various contexts are particularly valuable in the global arena of disaster management. One concern that may benefit from normalizing is the analysis of disaster loss trends. Previous studies have used a combination of inflation, wealth, and societal factors in their normalization of disaster loss methodologies. This study examines the various normalization methods in previous research and applies a selection of eight formulae to 50 years of disaster data in South Korea. The results show both decreasing and increasing trends in disaster damage losses based on the methods, but there are curious biases under the results that may be artifacts of Korea's unique experiences in economic development. The conclusion discusses how the case of Korea may help to clarify the optimal normalization methodology for other countries.

Communities with a high degree of vulnerability to disasters often experience greater impact from disasters. Understanding and identifying the extent of community vulnerability to natural disasters, would provide emergency managers and decision-makers with strategic direction in their efforts to improve local communities' capacity to natural disasters while reducing the degree of vulnerability and the negative impacts of disasters. This study aims to develop a methodology for constructing a set of indicators for deriving a community vulnerability index (CVI) in terms of social, physical, and natural environmental factors. The degree of community vulnerability to natural disasters is measured at 229 local municipalities in Korea. Shannon's entropy method is employed to assess the weight of each vulnerability factor in the local communities of Korea. In order to verify the measured CVI, this study also examines the relationship between the aggregated CVI using the entropy method and disaster losses.

The enhancement of bendability of flexible nanoelectronics is critically important to realize future portable and wearable nanoelectronics for personal and military purposes. Because there is an enormous variety of materials and structures that are used for flexible nanoelectronic devices, a governing design rule for optimizing the bendability of these nanodevices is required. In this article, we suggest a design rule to optimize the bendability of flexible nanoelectronics through neutral axis (NA) engineering. In flexible optical nanoelectronics, transparent electrodes such as indium tin oxide (ITO) are usually the most fragile under an external load because of their brittleness. Therefore, we representatively focus on the bendability of ITO which has been widely used as transparent electrodes, and the NA is controlled by employing a buffer layer on the ITO layer. First, we independently investigate the effect of the thickness and elastic modulus of a buffer layer on the bendability of an ITO film. Then, we develop a design rule for the bendability optimization of flexible optical nanoelectronics. Because NA is determined by considering both the thickness and elastic modulus of a buffer layer, the design rule is conceived to be applicable regardless of the material and thickness that are used for the buffer layer. Finally, our design rule is applied to optimize the bendability of an organic solar cell, which allows the bending radius to reach about 1 mm. Our design rule is thus expected to provide a great strategy to enhance the bending performance of a variety of flexible nanoelectronics. ; open ; 1 ; 1 ; 10 ; 7 ; scie ; scopus

AbstractThe high mountains of the Mediterranean are often considered as refuges of ancient traditions, particularly of pastoralism and brigandage. Is this image true? This paper reports the first systematic archaeological research on Aspromonte, Southern Calabria. Archaeological, cartographic and air photo evidence suggests that people used the high mountains in all periods from the Neolithic onwards. However, early usage was low-intensity and probably for special purposes such as iron-smelting, charcoal-burning and logging; only in the Classical Greek period was there sustained effort at inhabiting higher areas. The real development of the mountains came in the late-nineteenth and twentieth centuries. From the 1920s onwards, there were large-scale, state-fostered projects for economic exploitation of forests, political control of territory, and creation of a recreational landscape. These endeavors tied into modernist ideas of the state, as well as period concepts such as Alpinism and healthy outdoor recreation for city dwellers. Ironically, as soon as these modern efforts made the high mountains accessible, they were assigned a chronotope, and were reimagined as the exemplification of an ancient way of life. ; National Endowment for the Humanities and the Cambridge Humanities Research Grants
