Evaluation of a Web-based Error Reporting Surveillance System in a Large Iranian Hospital

BACKGROUND: Proper reporting of medical errors helps healthcare providers learn from adverse incidents and improve patient safety. A well-designed and functioning confidential reporting system is an essential component to this process. There are many error reporting methods; however, web-based systems are often preferred because they can provide¬¬¬¬ comprehensive and more easily analyzed information. This study addresses the use of a web-based error reporting system. METHODS: This interventional study involved the application of an in-house designed "voluntary web-based medical error reporting system." The system has been used since July 2014 in Nemazee Hospital, Shiraz University of Medical Sciences. The rate and severity of errors reported during the year prior and a year after system launch were compared. RESULTS: The slope of the error report trend line was steep during the first 12 months (B = 105.727, P = 0.00). However, it slowed following launch of the web-based reporting system and was no longer statistically significant (B = 15.27, P = 0.81) by the end of the second year. Most recorded errors were no-harm laboratory types and were due to inattention. Usually, they were reported by nurses and other permanent employees. Most reported errors occurred during morning shifts. DISCUSSION: Using a standardized web-based error reporting system can be beneficial. This study reports on the performance of an in-house designed reporting system, which appeared to properly detect and analyze medical errors. The system also generated follow-up reports in a timely and accurate manner. Detection of near-miss errors could play a significant role in identifying areas of system defects

Lärarens Syn På Disciplin i Klassrummet

Syftet med vårt arbete är att undersöka lärarens syn på disciplin i klassrummet. Examensarbete behandlar ämnet disciplin i klassrummet och dess påverkan när det gäller inlärningsmiljö och arbetsro i klassrummet. Vi observerade och intervjuade fyra lärare från årskurs 1, 2, 4, 5 i en grundskola. Deltagarna i vår intervju var mellan 32 -53 år, en manlig, resten var kvinnliga. Våra frågeställningar är: hur tänker lärare om innebörden av disciplin, vilka olika faktorer som enligt lärare kan resultera i ett bra disciplinerat klassrum, vad lärarna, anser påverkar ordningen respektive oordning samt pedagogers motiv till disciplin i klassrummet. Resultatet visar att trots att lärarna hade delvis olika syn på disciplin och olika metoder för att upprätthålla den, var de alla eniga om att läraren måste vara tydlig med sitt ledarskap och sina instruktioner för att upprätthålla disciplin i klassrummet

Simple models for predicting leaf area of mango (Mangifera indica L.)

Mango (Mangifera indica L.), one of the most popular tropical fruits, is cultivated in a considerable part of southern Iran. Leaf area is a valuable parameter in mango research, especially plant physiological and nutrition field. Most of available methods for estimating plant leaf area are difficult to apply, expensive and destructive which could in turn destroy the canopy and consequently make it difficult to perform further tests on the same plant. Therefore, a non-destructive method which is simple, inexpensive, and could yield an accurate estimation of leaf area will be a great benefit to researchers. A regression analysis was performed in order to determine the relationship between the leaf area and leaf width, leaf length, dry and fresh weight. For this purpose 50 mango seedlings of local selections were randomly took from a nursery in the Hormozgan province, and different parts of plants were separated in laboratory. Leaf area was measured by different method included leaf area meter, planimeter, ruler (length and width) and the fresh and dry weight of leaves were also measured. The best regression models were statistically selected using Determination Coefficient, Maximum Error, Model Efficiency, Root Mean Square Error and Coefficient of Residual Mass. Overall, based on regression equation, a satisfactory estimation of leaf area was obtained by measuring the non-destructive parameters, i.e. number of leaf per seedling, length of the longest and width of widest leaf (R2 = 0.88) and also destructive parameters, i.e. dry weight (R2 = 0.94) and fresh weight (R2= 0.94) of leaves

An inventory model for non-instantaneous deteriorating items with partial backlogging, permissible delay in payments, inflation- and selling price-dependent demand and customer returns

This paper develops an economic ordering policy model for non-instantaneous deteriorating items with selling price- and inflation-induced demand under the effect of inflation, permissible delay in payments and customer returns. Shortages are allowed and partially backlogged. The customer returns are assumed to increase with both the quantity sold and the product price. The main objective is to determine the optimal selling price, the optimal length of time in which there is no inventory shortage, and the optimal replenishment cycle simultaneously, to minimize the present value of the total profit. An efficient algorithm is presented to find the optimal solution of the developed model. Finally, a numerical example is extracted to solve the presented inventory model using the proposed algorithm

EVALUATING THE IMPACT OF CONSUMERS PROTECTION AND PRODUCERS ORGANIZATION ON CONSUMER SATISFACTION (CASE STUDY: IN GUILAN PROVINCE)

Abstract Nowadays the right of consumers and the necessity of supporting it by governments counted as the basic rights of consumers. On the one hand many consumers especially in developing countries are not aware of their rights. In Iran supporting consumers is undertaken by Consumers Protection and Producers Organization. Regarding available problems in this field, the current research was done with the title of "Evaluating the Impact of Consumers Protection and Producers Organization on Consumer Satisfaction". In this research 2 services of this organization have been considered; supporting consumers against price volatility, protection of domestic manufacturing and products. Regarding that subject, the research is applied one and regarding the method it is descriptivesurveying. Statistical society of the research includes all customers of chain store of Refah in Guilan province (Iran). For sampling the method of available convenient sampling was used. For data collection, questionnaire was used. After confirming validity of the questionnaire through content method and also confirming their reliability through cronbach's alpha method (a=77%) the obtained information has been considered for testing hypothesis by doing calculation of descriptive statistics and linear regression. The result of testing hypotheses is show that consumer protection against disproportionate price volatility and protection of domestic manufacturing and products have positive impact on consumer satisfaction

An Applicable Heuristic for Scheduling Multi-mode Resource Constraint Projects Using PERT Technique in the Presence of Uncertain Duration of Activities

In project planning process, resource over-allocation is a major shortcoming. The resource over-allocation causes the schedules not to be applicable in practice. Besides, in real projects, it is hard to predict the duration of activities since they may be changed due to lack of resources, delays in delivering resources, improper workers etc. that cause activities not to complete as predicted. Hence, it is important to develop a method that can schedule activities by considering different execution conditions. In this research, we focused on another aspect of solving resource over-allocation problem by considering uncertain activity duration. For this purpose, a mixed integer programming model is developed where the objective function is maximizing net present value of the project while duration of activities are not deterministic. Then a number of examples are solved using a heuristic algorithm. The results showed that the proposed algorithm can effectively solve the case studies with no over-allocated resources. Afterward, the algorithm is solved using the data of constructing a hospital. The results showed that the algorithm can successfully use for real projects

The effects of propolis on pro-oxidant–antioxidant balance, glycemic control, and quality of life in chronic kidney disease: a randomized, double-blind, placebo-controlled trial

Abstract Chronic kidney disease (CKD) is a progressive kidney damage with an increasing prevalence. Some evidence suggests that propolis as a novel antioxidant, anti-inflammatory, and immunomodulatory agent may have beneficial effects in CKD. The aim of this study was to evaluate the efficacy of propolis on some kidney function parameters, pro-oxidant–antioxidant balance (PAB), glycemic status, quality of life, and blood pressure (BP) in patients with CKD. In this study, 44 patients with CKD were randomly assigned to receive propolis capsules at a dose of 250 mg daily or placebo for three months. Of 44 randomized individuals, 35 completed the trial. At the end of the intervention (end of month three), improvement in some dimensions of health-related quality of life (HRQoL) (derived from Kidney Disease and Quality of Life Short-Form (KDQOL- $${\mathrm{SF}}^{\mathrm{TM}}$$ SF TM , v. 1.3) questionnaire) were significantly higher in the propolis group than the placebo group, even after adjustment for baseline values, present of diabetes, and age (P  0.05). No serious adverse events were reported throughout the study. Propolis supplementation may improve the HRQoL of CKD patients. More studies are needed to validate the adjunct use of propolis for metabolic control of CKD patients

JOINT PRICING AND REPLENISHMENT DECISIONS FOR NON-INSTANTANEOUS DETERIORATING ITEMS WITH PARTIAL BACKLOGGING, INFLATION- AND SELLING PRICE-DEPENDENT DEMAND AND CUSTOMER RETURNS

This paper develops an Economic Order Quantity (EOQ) model for non-instantaneous deteriorating items with selling price- and inflation-induced demand under the effect of inflation and customer returns. The customer returns are assumed as a function of demand and price. Shortages are allowed and partially backlogged. The effects of time value of money are studied using the Discounted Cash Flow approach. The main objective is to determine the optimal selling price, the optimal length of time in which there is no inventory shortage, and the optimal replenishment cycle simultaneously such that the present value of total profit is maximized. An efficient algorithm is presented to find the optimal solution of the developed model. Finally, a numerical example is extracted to solve the presented inventory model using the proposed algorithm and the effects of the customer returns, inflation, and non-instantaneous deterioration are also discussed. The paper ends with a conclusion and outlook to future studies

<p>This study was conducted to measure the diameter at breast height (dbh) of adult trees in pairs and the distance between them in woodlots, at York University around 3:30pm- 5:00pm.</p><br><br><p>Location: Data was collected at York University, at Keele St. and York Blvd, in the Woodlots.</p><br><p>Methods: In this field experiment,  transects measuring tapes were used to determine the distance between 10 pairs of sugar maple trees. The diameters were measured from the middle of the tree trunks, using a tape measure. Canopy coverage was determined by making square with fingers and holding it up, in order to gain an estimate regarding how much of the sky was seen. </p><br><p>Key to variables: Diameter at breast height (dbh), distance to nearest species, and canopy coverage were continuous and quantitative variables. </p><br><br><p>Prediction: It was predicted that the distance between two trees with a low dbh would be less than those with a greater dbh, since the smaller the dbh, the smaller the tree and therefore, the less branches and canopy coverage it would have. Thus, the space it occupies would be less and the trees could form closer to each other.</p><br><p>Hypothesis: Tree pairs with lower dbh are closer to each other than pairs with greater dbh. Also canopy coverage is greater for trees with a higher dbh. </p><br
