Model Determination of Delayed Causes of Analgesics Prescription in the Emergency Ward in Arak, Iran
Cyrus, Ali,Moghimi, Mehrdad,Jokar, Abolfazle,Rafeie, Mohammad,Moradi, Ali,Ghasemi, Parisa,Shahamat, Hanieh,Kabir, Ali The Korean Pain Society 2014 The Korean Journal of Pain Vol.27 No.2
Background: According to the reports of the World Health Organization 20% of world population suffer from pain and 33% of them suffer to some extent that they cannot live independently. Methods: This is a cross-sectional study which was conducted in the emergency department (ED) of Valiasr Hospital of Arak, Iran, in order to determine the causes of delay in prescription of analgesics and to construct a model for prediction of circumstances that aggravate oligoanalgesia. Data were collected during a period of 7 days. Results: Totally, 952 patients participated in this study. In order to reduce their pain intensity, 392 patients (42%) were treated. Physicians and nurses recorded the intensity of pain for 66.3% and 41.37% of patients, respectively. The mean (SD) of pain intensity according to visual analogue scale (VAS) was 8.7 (1.5) which reached to 4.4 (2.3) thirty minutes after analgesics prescription. Median and mean (SD) of delay time in injection of analgesics after the physician's order were 60.0 and 45.6 (63.35) minutes, respectively. The linear regression model suggested that when the attending physician was male or intern and patient was from rural areas the delay was longer. Conclusions: We propose further studies about analgesics administration based on medical guidelines in the shortest possible time and also to train physicians and nurses about pain assessment methods and analgesic prescription.

Wind Attribute Time Series Modeling & Forecasting in IRAN
Fahimeh Ghorbani,Sadigh Raissi,Meysam Rafei 동아시아경상학회 2015 The East Asian Journal of Business Economics Vol.3 No.3
wind speed forecast is a crucial and sophisticated task in a wind farm for planning turbines and corresponds to an estimate of the expected production of one or more wind turbines in the near future. By production is often meant available power for wind farm considered (with units KW or MW depending on both the wind speed and direction. Such forecasts can also be expressed in terms of energy, by integrating power production over each time interval. In this study, we technically focused on mathematical modeling of wind speed and direction forecast based on locally data set gathered from Aghdasiyeh station in Tehran. The methodology is set on using most common techniques derived from literature review. Hence we applied the most sophisticated forecasting methods to embed seasonality, trend, and irregular pattern for wind speed as an angular variables. Through this research, we carried out the most common techniques such as the Box and Jenkins family, VARMA, the component method, the Weibull function and the Fourier series. Finally, the best fit for each forecasting method validated statistically based on white noise properties and the final comparisons using residual standard errors and mean absolute deviation from real data.

Purpose: Mesenteric embolization is an integral part in the management of acute lower gastrointestinal (GI) bleeding. The aim of this study was to highlight our experience after adopting mesenteric embolization in the management of acute lower GI hemorrhage. Methods: A retrospective review of all cases of mesenteric embolization for acute lower GI bleeding from October 2007 to August 2012 was performed. Results: Twenty-seven patients with a median age of 73 years (range, 31 to 86 years) formed the study group. More than half (n = 16, 59.3%) of the patients were on either antiplatelet and/or anticoagulant therapy. The underlying etiology included diverticular disease (n = 9), neoplasms (n = 5) and postprocedural complications (n = 6). The colon was the most common bleeding site and was seen in 21 patients (left, 10; right, 11). The median hemoglobin prior to the embolization was 8.6 g/dL (6.1 to 12.6 g/dL). A 100% technical success rate with immediate cessation of hemorrhage at the end of the session was achieved. There were three clinical failures (11.1%) in our series. Two patients re-bled, and both underwent a successful repeat embolization. The only patient who developed an infarcted bowel following embolization underwent an emergency operation and died one week later. There were no factors that predicted clinical failure. Conclusion: Mesenteric embolization for acute lower GI bleeding can be safely performed and is associated with a high clinical success rate in most patients. A repeat embolization can be considered in selected cases, but postembolization ischemia is associated with bad outcomes.
