Ismail Islek, Sancar Baris, Ali O Katranci, Ender Ariturk, Nuran Gurses
Annals of Clinical Microbiology and Antimicrobials , 2003, DOI: 10.1186/1476-0711-2-1
Abstract: A 13-year-old girl with appendicitis developed hypersensitivity vasculitis on the fifth day of cefoperazone/sulbactam therapy. Hypersensitivity vasculitis resolved gradually after removal of the agent on the seventh day and did not recur. Although hypersensitivity vasculitis has multiple causes, coexistence of hypersensitivity vasculitis and cefoperazone treatment, and the quite resolution of the disease after removal of the drug, strongly favours a causative relationship.To our knowledge, this is the first report of a hypersensitivity vasculitis associated with cefoperazone.Cefoperazone is a common antibiotic drug used mainly to treat serious infections. Reported adverse effects of this drug include urticaria, maculopapular and erythematous skin rash and rarely anaphylaxis and bronchospasm [1,2]. Cefoperazone has not been reported to cause vasculitic complications before. We report a case of hypersensitivity vasculitis associated with cefoperazone/sulbactam.A 13-year-old girl was admitted to Ondokuz May1s University Hospital with a 3-day history of abdominal pain and fever. She had no history of allergic reactions, connective tissue disease, respiratory tract infection and/or use of antibiotics or another drug. Physical examination revealed abdominal tenderness and defense, and positive Rovsing's sign in the right lower quadrant. The white-cell count was 20.700 per cubic milimeter with 78 percent neutrophils, 20 percent lymphocytes and 2 percent monocytes. Hemoglobin was 12.1 g/dl. Erythrocyte sedimentation rate (ESR) was slightly elevated at 46 mm/hour. The patient was referred to the pediatric surgery department and acute perforated appendicitis was considered. Cefoperazone/sulbactam 100 mg/kg/day two in divided doses was initiated on the first day of admission. Abdominal exploration was performed on the second day of admission and a gangrenous appendicitis with adhesions to peripheral tissue and purulent material around the caecum was observed.

Journal of Financial Risk Management (JFRM) , 2015, DOI: 10.4236/jfrm.2015.43013
Abstract: This study aims to measure the foreign exchange risks that the insurance companies are exposed to. In this context, this study analyzes 7 insurance companies listed in Borsa Istanbul (Istanbul Stock Exchange). The foreign exchange risks that the insurance companies are exposed to were measured using VaR models, Historical Simulation and Monte Carlo Simulation methods. Data obtained from the analysis show the losses that the insurance companies suffer due to exchange risk. The losses calculated using the Monte Carlo Simulation were found to be greater than the losses calculated using Historical Simulation.

Abstract: The north-western part of Sudan, which is the driest region on earth has revealed newly surface and near surface paleodrainage network underneath sand sheets indicating the possibilities for economic groundwater reservoirs. Advanced Space-born Thermal Radiometer (ASTER), the Shuttle Radar Topography Mission (SRTM ~90 m) DEMs and Quickbird images corroborate the presence of surface and near surface paleodrainage network. Bivariate quadratic surfaces with moving window size of 3 × 3 were fitted to the SRTM DEM. The second derivative surface curvature was calculated to reveal landform classes that may receive most of fossil water. The results showed that the new unnamed depression which recharges by a longitudinal paleodrainage network may receive vast amount of groundwater during humid phases. The results demonstrate that the D8 and curvature algorithms are very efficient tools for revealing and characterizing hydrological elements in arid and semi-arid regions and they provide information for hydrological exploration in remote deserts over large scale prior to geophysical survey.
Overcoming Object Misalignment in Geo-Spatial Datasets  [PDF]
Ismail Wadembere, Patrick Ogao
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.64028

In integrating geo-spatial datasets, sometimes layers are unable to perfectly overlay each other. In most cases, the cause of misalignment is the cartographic variation of objects forming features in the datasets. Either this could be due to actual changes on ground, collection, or storage approaches used leading to overlapping or openings between features. In this paper, we present an alignment method that uses adjustment algorithms to update the geometry of features within a dataset or complementary adjacent datasets so that they can align to achieve perfect integration. The method identifies every unique spatial instance in datasets and their spatial points that define all their geometry; the differences are compared and used to compute the alignment parameters. This provides a uniform geo-spatial features’ alignment taking into consideration changes in the different datasets being integrated without affecting the topology and attributes.

Information Reach and Range Impact on Interorganizational Systems Platforms  [PDF]

Intelligent Information Management (IIM) , 2014, DOI: 10.4236/iim.2014.61001

Organizations tend to use information systems (IS) applications that require data to be exchanged between different parties, while data exchange is restricted with information reach and range, which determines the organizations’ IT platform. To determine the best platform, a comparison between electronic data interchange (EDI) and web services was conducted depending on certain criteria, and then we match the results with the information reach and range. The main findings show that the web services platform can take place when the range of information access is required by anyone and anywhere regardless of IT base. EDI can take place when the range of information access doesn’t exceed the organizations’ boundaries. But when the range of information access exceeds the organizations’ boundaries, still between certain partners, web services or EDI can take place, and thus the organization can select them from those platforms depending on other criteria such as security, and cost.

American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.64044
Abstract: Many firms have spent large investments in developing and implementing information technologies and systems to enhance their supply chain performance with little benefit, while others have spent similar amount of money with great success [1]. The IT productivity paradox in supply chain performance is widely cited as a polemic that needs more investigation. This work reviews the body of knowledge related to the relationship between IT and supply chain performance through a systematic literature review study, following a pre-defined search protocol that can be used by other researchers to review other subjects in the area of information technology, to provide an overview of the state of the art and identify research challenges and gaps. 33 papers are finally selected, in which three main themes of research, nineteen IT-relates characteristics, and seventeen mediator factors to enhance supply chain performance are identified. The indirect effect of IT in SCP is the major findings in the literature. This work presents some new guidelines of research.

Abstract: A cross-sectional study was carried out aimed to estimate sero-prevalence of camel trypanosomiasis and to investigate the related risk factors of the disease in Four Selected Villages of Galkayo, Mudug region from 14th March 2016 up to 20th April 2016. Blood samples were collected from 69 randomly selected camels of the four study villages, and samples were allowed to clot at room temper to detect the sero-prevalence of trypanosome using Card Agglutination Test for Trypanosomiasis (CATT). The results indicated that the overall sero-prevalence of trypanosomiasis in camels that 15.9% (11) samples were positive for trypanosome evansi (T. evansi) was recorded. Higher infection was found in female (19.4) as compared to male (11.1), However, there is no statistically significant difference in sero-prevalence between sex categories (P > 0.05). High Test infection of sero-prevalence was noted 20% in young age (<10) followed by 19% in adult age group (>10), and there was statistically significant difference (P < 0.05) in susceptibility among age groups. These results seem to indicate that T. evansi infection is high in the study area. There is need of further control of camel trypanosomiasis through the uses of curative and prophylactic drugs to avoid the various problems.

Abstract: The software cost estimation aims to predict the most realistic effort that is required to finish a software project and so it is critical to the success of a software project management. A Software Cost Estimation affects nearly all management activities, including project bidding, resource allocation and project planning. It is affected by a number of factors, such as implementation efficiency, as well as how much the various reviews and studies completed prior to the software development stage cost. Accurate cost estimation will help us to complete the project on time and within budget. Accurate estimation is important because it has led to extensive research into the methods of software cost estimation. Some important software cost estimation methods have been studied in this research work. In addition, we have set out own criteria, which has been used to compare all the different selected methods. We have also given a score for each evaluation criteria, so that we can compare the different methods numerically for cost estimation. Our observations have shown that it is best to use a number of different estimating techniques or cost models, and then compare the results before determining the reasons for any of the large variations. None of the methods are necessarily better or worse than the others. We found, in fact, that their strengths and weaknesses often complement each other. Therefore, the main conclusion is that there is no one single technique that is best for every situation, and the results of a number of different approaches need to be carefully considered to discover what is the most likely to produce estimates that are realistic.
