Geographical structures and the cholera epidemic in modern Japan: Fukushima prefecture in 1882 and 1895
Chun-Lin Kuo, Hiromichi Fukui
International Journal of Health Geographics , 2007, DOI: 10.1186/1476-072x-6-25
Abstract: Changes in diffusion patterns between 1882 and 1895 reflect improvements in the Fukushima transportation system and growth in social-economic networks. The data reveal different diffusion systems in separate regions in which residents of Fukushima and neighboring prefectures interacted. Our model also shows that an area in the prefecture's northern interior was dominated by a mix of diffusion processes (contagious and hierarchical), that the southern coastal region was affected by a contagious process, and that other infected areas experienced relocation diffusion.In addition to enhancing our understanding of epidemics, the spatial-temporal patterns of cholera diffusion offer opportunities for studying regional change in modern Japan. By highlighting the dynamics of regional reorganization, our findings can be used to better understand the formation of an urban hierarchy in late nineteenth century Japan.Researchers from different disciplines are showing a growing interest in disease and its geographical effects, with studies focusing on the value of detecting spatial concentrations of disease, isolating processes that result in disease hot-spots, and analyzing the space-time dynamics of disease diffusion. A strong example of recent advancements in this area is [2] work on the geographical structures of international epidemics, resulting in models of how epidemic diffusions move through communities, regions and countries. The term geographical structures refers to the patterns and features of human-environment interactions in specific locations. In medical geography, studies of the geographical structures of disease emphasize diffusion and analyses of individual disease factors [8].Regarding cholera, the most serious global epidemic in the nineteenth century, several research teams have gathered evidence showing that its diffusion was dominated by geographic factors (see, for example, [3-6]). Since diffusion primarily occurs via survivors who transport a disease from
STRESS FRACTURE OF THE ULNA IN A BREAK-DANCER
Yu-Hsu Chen,Chun-Lin Kuo,Leou-Chyr Lin,Shyu-Jye Wang
Journal of Sports Science and Medicine , 2008,
Abstract: Break dancing is a popular activity in teenagers and is associated with severe trauma to bones and tissues. We report the first known case of a break dancer with an ulnar stress fracture. Such injuries occur in a variety of sports due to substantial stress on the ulna and repetitive excessive rotation of the forearm. In this study we describe a patient who experienced an ulnar stress fracture during break dancing training. The diagnosis was established by history and physical examination. Initial radiographic findings were negative. However, radiographs taken 3 months after initial presented revealed callus formation over the ulnar shaft. This suggested that readjustment is required in break dancing training protocols. It is important to increase awareness of this injury among physicians to expedite the diagnosis and to prevent the possibility of conversion to an overt fracture in the future

Abstract: Through relevant analysis of the changing space in the peasants’ average net income from 2005 to 2006 in 139 counties, towns and regions, this thesis works out the overall space statistic index Moran’s I and partial statistic index LISA, which well demonstrates the change of net income made by peasants in this area, and obviously manifest disharmony and difference from one region to another, especially from the east to the west. To solve the problem of big gap between the east and west, more efforts should be made to accelerate the development of the west. Regions in the middle and the west should renew developmental concept, rely on, serve and interconnect with central cities, speed up the transition of the surplus labor, put more investment into the construction of the agricultural infrastructure, strive to develop cooperative economic organizations and agricultural leading enterprises, energetically push the industrialization of agriculture. Key words: average net income of peasants; relationship of space; Moran’s I; LISA; regional economic differences Résumé: En faisant des analyses sur la corrélation spaciale de la variation des revenus moyens des paysans entre 2005-2006 dans 139 districts et villes dans la province du Shangdong, l’auteur a obtenu l’indice statistique de l’ensemble spacial- Moran’I et l’indice statistique de localité régionale-LISA. Ces deux indices ont bien démontré les variations des revenus moyens des paysans dans tous les districts et villes de la province du Shangdong, les disparates et les écarts entre les régions et surtout entre l’est et l’ouest. Pour résoudre le problème d’un écart trop important entre l’est et l’ouest, il faut accélérer le développement des régions dans l’ouest. Les régions du centre et de l’ouest doivent renouveler leur conception du développement et essayer de s’appuyer sur les villes centrales, les servir et les aboucher pour transférer les mains-d’oeuvre surplus, investir plus pour les infrasturctures de l’agriculture, soutenir les organisations économiques de coopération dans la campagne et les entreprises leaders agricoles et promouvoir l’industrialisation de l’agriculture. Mots-clés: revenus moyens des paysans ; corrélation spaciale ; Moran’I, LISA ; différence de l’économie régionale 摘要:通過對山東省139個縣市區2005-2006年農民人均純收入變化的空間自相關分析,得出總體空間統計指數Moran’sI與局部統計指標LISA,這兩個指數在描述山東省各縣市區農民人均純收入變化時具有顯著作用,並明顯體現出區域之間的不協調性和差異性,尤其是東西部差距明顯。解決東西部差距過大問題,需要重點加快西部地區發展。中西部地區要進一步更新發展理念,依託、服務、對接中心城市,加快剩餘勞動力轉移,加大對農業基礎設施的投入,大力發展農村合作經濟組織和農業龍頭企業,積極推進農業產業化經營。 關鍵字:農民人均純收入;空間相關性;Moran’s I;LISA;區域經濟差異

The dihedral angle between the two substituted benzene rings is 12.7 (2)°. In the crystal structure, molecules are linked through intermolecular N—H...O and O—H...O hydrogen bonds, forming layers parallel to the bc plane.
An extension of gas-kinetic BGK Navier-Stokes scheme to multidimensional astrophysical magnetohydrodynamics

Physics , 2010,
Abstract: The multidimensional gas-kinetic scheme for the Navier-Stokes equations under gravitational fields [J. Comput. Phys. 226 (2007) 2003-2027] is extended to resistive magnetic flows. The non-magnetic part of the magnetohydrodynamics equations is calculated by a BGK solver modified due to magnetic field. The magnetic part is treated by the flux splitting method based gas-kinetic theory [J. Comput. Phys. 153 (1999) 334-352 ], using a particle distribution function constructed in the BGK solver. To include Lorentz force effects into gas evolution stage is very important to improve the accuracy of the scheme. For some multidimensional problems, the deviations tangential to the cell interface from equilibrium distribution are essential to keep the scheme robust and accurate. Besides implementation of a TVD time discretization scheme, enhancing the dynamic dissipation a little bit is a simply and efficient way to stabilize the calculation. One-dimensional and two-dimensional shock waves tests are calculated to validate this new scheme. A three-dimensional turbulent magneto-convection simulation is used to show the applicability of current scheme to complicated astrophysical flows.

TENG Yun,HE Chun-lin,YUE Miao
Journal of Chongqing Normal University , 2010,
Abstract: Because of good characteristics of the abstract classification, neural networks have become an effective tool for resolving issues related to recognition, and have been applied to the research and development of speech recognition system. A speech recognizer system comprises of two blocks, Feature Extractor and Recognizer. For increasing the recognition accuracy, this paper proposes two types of speech recognition system whose recognition block uses the recurrent neural network(RNN) and multi layer perceptron(MLP) respectively. Furthermore, the main work steps of Feature Extractor (FE) block is introduced and the structure of two types of neural networks mentioned above is discussed. Using a standard LPC Cepstrum, the FE translates the input speech into a trajectory in the LPC Cepstrum feature space. The recognizer block discovers the relationships between the trajectories and recognizes the word. The results show that the MLP's recognition accuracies were better than the RNN's,while the RNN's recognition accuracies achieved 85%.
