Assessment of Waterlogging Risk in Lixiahe Region of Jiangsu Province Based on AVHRR and MODIS Image

Four images of 1991 AVHRR, 2003 and 2007 MODIS were used to extract waterlogging inundated water of three years, and three inundated water maps were overlaid to estimate waterlogging affected frequency. Based on wa-terlogging affected frequency, waterlogging hazard of pixel scale was assessed. According to the weighed score of area percentage of different waterlogging affected frequency in 13 counties/cities of Lixiahe region, waterlogging hazard rank of every county/city was assessed. Waterlogging affected frequency map and 1km×1km grid landuse map were used to assess waterlogging risk of pixel scale; and then waterlogging risk rank of every county/city was assessed by the similar method by which waterlogging hazard rank of every county/city was assessed. High risk region is located mainly in core zone of Lixiahe hinterland, medium risk region is adjacent to high risk region, and low risk region is located in the most outlying area of risk zone and mainly in south to middle part of Lixiahe region. Xinghua and Gaoyou belong to high risk city, Jiangyan belongs to medium risk city, and the other counties/cities have low or lower waterlogging risk. The method of assessing waterlogging risk in this paper is simple and applicable. This paper can provide guidance for the waterlogging risk analysis in broader area of Huaihe River Basin.

Multicausality in fatty liver disease:Is there a rationale to distinguish between alcoholic and non-alcoholic origin?

Apart from alcohol,there are other factors that may induce complications,which resemble alcohol-related liver disorders.In particular,obesity has been brought into focus as a risk factor for fatty liver disease.The term "non-alcoholic" fatty liver disease is commonly used to distinguish between obesity-related and alcohol-related hepatic steatosis.This review uses the epidemiological perspective to critically assess whether it is necessary and useful to differentiate between alcoholic and "nonalcoholic" fatty liver disease.The MEDLINE database was searched using the PubMed search engine,and a review of reference lists from original research and review articles was conducted.The concept to distinguish between alcoholic and "non-alcoholic" fatty liver disease is mainly based on specific pathomechanisms.This concept has,however,several limitations including the common overlap between alcohol misuse and obesityrelated metabolic disorders and the non-consideration of additional causal factors.Both entities share similar histopathological patterns.Studies demonstrating differences in clinical presentation and outcome are often biased by selection.Risk factor reduction is the main principle of prevention and treatment of both disease forms.In conclusion,alcoholic and "non-alcoholic" fatty liver diseases are one and the same disease caused by different risk factors.A shift from artificial categories to a more general approach to fatty liver disease as a multicausal disorder may optimize preventive strategies and help clinicians more effectively treat patients at the individual level.

Vaccination Statistics and Reality： How Many Horses Are Really Vaccinated against Equine Influenza？

Standard schedules for equine influenza vaccinations have been published in Finland. However, no knowledge about the actual number of vaccinations has been available. Based on previous preliminary studies in slaughterhouses and among horse owners, it was suspected that vaccination recommendations are not always followed. The aims were to investigate vaccination status against equine influenza among Finnish racehorses in regional competitions. Vaccination status was investigated： （1） by utilizing database vaccination information of show jumping and dressage horses and （2） by carrying out a survey among horse industry experts. A total of 400 horses were selected at the beginning of the Finnish competition season in 2012 and five experts （key persons） were invited to a repeated survey implemented by Delphi techniques. Overall, 50%-100% of horses were properly vaccinated depending on the source available. Thirty-four percent （34%） of the horses had the competition license but no vaccination markings in the database. Differences between types of competition （show jumping and dressage） and between Southern and Northern parts of Finland were found. Vaccinations of show jumping horses were registered more often than vaccinations of dressage horses. Ninety percent （90%） of unvaccinated horses in the database were eight years or older. It can be concluded that equine influenza vaccination registry coverage among racehorses in Finland is incomplete. This poses a risk of misunderstanding, and the growing responsibility of competition organizers.

Explorations of Public Participation Approach to the Framing of Resilient Urbanism

Under the framework of developing resilient and livable cities, this study was aimed at engaging local communities to achieve the goal of public participation. Given the prevalence of smart mobile devices, an interactive app called ＂Citizen Probe＂ was designed to guide users to participate in building resilient and livable urban spaces by enabling users to report the condition of their living environment. The app collects feedback from users regarding the perceived condition of the urban environment, and this information is used to further develop an open online index system. The index system serves as a guide for the public to actively transform their city into a resilient and livable urban environment. The app was designed for the reporting of flood incidents with the objective of resilient disaster prevention, which can be achieved by enabling users to identify disaster conditions in order to develop a database for basic disaster information. The database can be used in the prevention and mitigation of disasters and to provide a foundation for developing indices for assessing the resilience and livability of urban areas. Three communities in Taichung, Taiwan, participated in the study. Residents of these communities were requested to use the app and identify local environmental conditions to obtain spatial data according to four stages in disaster response： assessment, readiness, response, and recovery. A volunteered geographic information database was developed to display maps for providing users with current reports ofpredisaster risk assessment, disaster response capacity, real-time disaster conditions, and overall disaster recovery. In addition, the database can be used as a useful tool for researchers to conduct GIS analyses and initiate related discussions. The interactive appraises public awareness on disaster prevention and makes disaster prevention a daily norm. Further discussion between the public and experts will be initiated to assist in policy management pertaining to the ongoing development of cities in addition to improving disaster prevention and response measures.

Testing Point of Care Portable Data Capture in a Hospital HIV Transmission Prevention Programme and Experience from Computerized Patient Management in a Sub-Saharan Clinic Setting

Clinicians involved in HIV/AIDS （Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome） prevention of mother to child transmission （PMTCT） programme and research activities can benefit from the advantages that computerized systems add to medical practice even in resource constrained sub-Saharan clinic settings. Their continued use of paper based systems presents clinical data management and patient care challenges. A portable point of care data capture electronic system and a computerized clinic patient management system （CCPMS） were implemented to remedy these challenges. PMTCT report compilation was easier with the portable data collection system whose data were found to be more complete and accurate with a 0.83% error rate compared to a 4.1% error rate in the paper registers. A resounding majority of clinicians preferred using the new CCPMS with many of the view that it improved drug inventory and general clinic management with a positive effect on patient care.

Research and application of flood detention modeling for ponds and small reservoirs based on remote sensing data

This paper proposes a method of small reservoir flood detention modeling that utilizes data from the American land resources satellite Landsat TM/ETM+. Precipitation and potential evapotranspiration are taken as the control conditions in this method on the basis of basin terrain classification. The objective of this method is to solve the question of a small-scale water conservancy project’s influence on flood forecasting precision, which can be used in the basin with multitudinous small reservoirs in the upstream region and can help estimate non-runoff data for small reservoir runoff. Taking the 20060826 flood as an example, the flood detention quantity of 19 small reservoirs is modeled. The results show that the absolute error of the total flood detention quantity is 0.2×10 4 m 3 , and the relative error is 0.12%. The flood detention quantity of small reservoirs in the entire basin is then modeled using this method, and the primary flood forecasting model is adjusted. After adjustment, the precision is significantly improved, with the relative error decreasing from 31.8% to 10.1%.
