  • A Preliminary Study on Constructing the Bed Sounding Data from DEM

    Accurate riverbed information, including riverbed shape, sounding data and elevation data, is needed to simulate the process of flooding in flooded areas by using two-dimensional hydrodynamic model. DEM data is an important feature reflecting topographic changes and plays an important role in hydrological model analysis.However, in the plain area where DEM elevation changes are very small, the extraction and simulation of river network are of low accuracy in the process of hydrologic analysis, and there are great errors in watershed division. Taking the Mihe river basin, shouguang city, shandong province as the research object, based on WMS to abnormal proofreading is smoothing the center line of the river, get in line with the physical meaning of vector river network, the inversion to the original elevation data (DEM), and on this basis, with the river elevation information center line interpolation, construct a sounding data of river model, provide technical support for the two-dimensional hydrodynamic model.

  • Oral Ivermectin should be considered as a Magic Therapy for Scabies with 98% Cure

    Background: Scabies is one of the commonest endemic pruritic diseases all over the worldwide. Many topical therapeutic options for scabies are available, but none of them could be accepted by many patients as all of them need covering the whole body by ointment overnight. Accordingly patients are looking for safe oral therapy like many other diseases. Objective: To assess the effectiveness of oral ivermectin in the treatment of scabies. Patients and Methods: This single, blinded, therapeutic work was conducted in the Center of Dermatology and Venereology, Baghdad Teaching Hospital, Baghdad, Iraq during the period from April 2018 through October 2019. Fifty of patients with scabies were involved in this study. All socio-demographic data that related to the disease were obtained from each patient. History and clinical examination was done for each case to establish the diagnosis. Fifty patients treated by ivermectin tablet 200 microgram per kg as a single dose on empty stomach and repeated after one week. The patients were seen regularly every 2 weeks for 4 weeks duration after stopping therapy, to re-asses cure and to report any local or systemic side effects. Results: A total of 50 patients were included in this study, 21 (42%) males and 29 (58%) females. The ages of males ranged from 5-47 with a mean 20.90±13.034 years; while the age range of females ranged from 3-67 (30.69±18.766) years. At the end of four weeks after stopping therapy , the response to treatment was as follows: Response in 49 (98%) patients and no response in 1 (2%) patients. No cutaneous or systemic side effects were noticed in any patients, while the recurrence or relapse rate was documented in 2 (4%) patients. Conclusion: Oral ivermectin had achieved cure of scabies in 98% of patients, hence it should be considered as a mass treatment in…

  • A Paradigm Synthesis Of The Relevance Of Fieldwork In Geographic Research

    This paper examined the concept of fieldwork and its relevance in geographic studies. In particular, the paper evaluates the pros and cons of fieldwork, and gave reasons why fieldwork is important in geographic research. It was further reiterated that like the laboratory of pure sciences, the field is the laboratory of the geographers as well as other related earth science disciplines because it affords the researcher the opportunity to collect first-hand data and relevant information that may eventually assist in carrying out a reliable research. The stages, benefits and the different approaches to fieldwork are examined. Constraints associated with fieldwork and solutions are provided. It was re-emphasized that although fieldwork is capital intensive and time consuming, early preparations together with a well-articulated aim and objectives, scope and methodology will eventually ensure a successful fieldwork. As a proof of concept, an evaluation of the empirical field studies of Charles Darwin that involved detailed fieldwork in its execution reaffirmed that the field remains a major source of data for any successful geographic research.


    Spatio-temporal analysis is one of the suitable method in crime analysis. It is ability to visualize the spatial patterns and control emotionally over a time-ordered sequence of spatial variation. It has been involved the spatial modeling and models of location- allocation, spatial interaction, spatial choice with search, spatial optimization and space-time. Spatio-Temporal Analysis of Crime (STAC) is a powerful tool to identify the crime patterns and detect the crime hot clusters in identifying the hotspot areas. The aim of the objective study is to analyze the spatial effects based on space and time difference among the divisions (space and time) and rate of change. The different types of crime occurrence data were collected from fourteen rural police jurisdiction (2003-2006) in Coimbatore district, TamilNadu. For this analysis, crime occurrence data were used through ArcGIS 10.2 version. The study was analyzed the random walk incidences, and moving path of the peak incidences which are effective models used for entire surrounding area. The study was concluded that spatial-temporal dimension of crime in rural police jurisdictions and explaining how these outcomes used to assist the advance development of crime prevention strategies.

  • Outsourcing Human Resource Functions and their Impact on Organizational Performance

    In today’s rising competition, the benefit generated by the development of high organizational quality is becoming more important. The role of human resource tasks and the culture of organizations can impact the achievement of substantial organizational effectiveness, which in return draw much more attention from both theoreticians and practitioners. Outsourcing is deemed one of the tools which companies use to reinforce their core competencies to assign their resources effectively. The rise of globalization has transformed outsourcing into one of the broadly adopted business plans towards supplying exceptional services to consumers. As can be seen by the ever-increasing trends in outsourcing, the literature on how outsourcing activities affect manufacturing companies’ results is insufficient. The main aim of this research was to investigate the impact on the performance of the outsourcing of human resources functions. Therefore, the results revealed that outsourcing HR functions play an important role in the improvement of organizational performance which can be characterized in three major dimensions; productivity, profitability, and cost efficiency. This study is limited to literature analysis and in future the three dimensions found by research can be investigated empirically. Policy makers and human resource managers can incorporate the strategies suggested by study to increase the performance of their organization.


    Introduction The active methodology is an educational conception that stimulates critical-reflexive teaching-learning processes. Objective to apply the Arco de Maguerez in the Jardim Oasis community, in the municipality of Iguatu-CE. Methodology The first method was applied to the Hanlon method, in which priorities were established, based on the criteria of magnitude, severity, effectiveness and feasibility. Each criterion was analyzed using numerical score scores: magnitude (1-10); severity (1-10), effectiveness (0.5-1.5) and feasibility (0 or 1). It was through the observational analysis that the problematization “difficulty in adhering to the treatment of alcoholism” was highlighted. As a methodological framework, he used the Maguerez Arch based on “five steps”: observation of reality; key points of the problem; theorization; hypotheses of solution; application of action in reality. Results First Step – Observation of Concrete Reality. Second Step – Determination of Key Posts Third Step – Theorizing: There is a consensus in the literature on the low adherence rate of dependents, the dropout rates are generally above 50%. The literature found that more than 50% of patients evade in the first month. Fourth Step – Solution Hypotheses: Establish Links; inform; use harm reduction policy. Step Five – Application to Reality; Action plans to improve the problem in the reference territory. Conclusion It was understood that despite being a pedagogical instrument focused on the teaching – learning process, it can be fully applied in the daily routine of health services, starting from a social reality up to the moment of effective

  • Socio-demographic correlates of heavy drinking after hospital discharge among Thai alcohol-dependent patients: 6-month follow-up

    Background: After receiving in-patient treatment for alcohol abuse, alcohol-dependent patients (ADP) are at risk to return to heavy drinking. Little has been known regarding the correlates of socio-demographic and heavy drinking within 6-month after inpatient treatment. Objectives: This study aims to examine the socio-demographic correlates of heavy drinking among Thai ADP after hospital discharge within six-months. Methods: A prospective cohort study of 618 ADP who received inpatient treatment at two tertiary care hospitals in Northern Thailand between July and December 2014. Heavy drinking is defined by the World Health Organization as ≥5 standard drinks for men and ≥4 standard drinks for women per occasion. Heavy drinking data was collected using a Timeline Follow Back Calendar (TLFB) every month after discharge. Other measures included the Alcohol Use Disorder Identification Test (AUDIT), Rosenberg Self-esteem Scale, Alcohol Craving Control (ACC), Severity of Alcohol Dependence Questionnaire (SADQ), and demographic questionnaires. Results: 618 participants present with a mean age of 43.28 (SD=10.01) years, 94.2% male, 216 (35%) reported that family members are drinkers, and 400 (70.7%) continue to exhibit heavy drinking behaviour. The logistic regression model revealed that age at onset of alcohol use was correlated with heavy drinking after hospital discharge within 6 months (p

  • Development of a Health Information Exchange (HIE) system using the Unstructured Supplementary Service Data (USSD) Technology

    Most advanced nations have existing software systems that enforce a significant level of Health Information Exchange interoperability. A straightforward implementation or integration of the technique of such an application into the healthcare system in regions that have infrastructure challenges may not achieve the maximum result. Existing EHR interoperability solutions are primarily Web-based and are explicitly compatible to particular health standards. Resulting from this, such current technologies also need, at the very least, secure access to internet connectivity.On the other hand, several regions around the world (especially in developing countries) are characterized with bad internet accessibility, imbalanced spread of computer technology and literacy, and acute information breach.Therefore, this work aims to develop a system that allows patient records to be exchanged between health facilities given the challenge of lack of ubiquitous internet connectivity, unreliable internet access and also bridging the digital divide gap.This research will have positive impacts on different stakeholders in the health sector. Health institutions can access patients’ information evading the issue of poor or no internet connectivity. As a result of this, healthcare professionals will be able to give better and prompt treatments in cases of emergencies and avoid medical errors. Medical practitioners will also not have to deal with the communication gap or barrier when seeing a patient with low literacy level.This research would not only be of relevance to the health sector, it can also be adapted by other sectors using the USSD technology as a means of storage and retrieval of information.
