Employee value is a basic concept of human resource and more important in measuring. Measuring method for employee value introduced qualitatively till now. So that, consider component for employee value and achieved based on analysis. In literature there aren`t integrated component and any questionnaire for measuring, but could be compared the result based for fieldwork. Field researchers problems are that change the result by changing the sample and take time. In this paper we try to present the mathematical formula to calculate the trend of Employee value. Presented formula EVRFM composed of year of employment, last promotion year in EVR and number of promotion in EVF and percent of annual salary increased in EVM. To evaluate the formula data ware gathered from private insurance company in Tehran and calculating the employee value with EVRFM. Of the population 384 were gathered. Questioners evaluated employee value with 3components, attraction, satisfaction and loyalty. The result from EVRFM and analysis of questioners are as the same trend for evaluating the employee value. Thus EVRFM could be used for trend of employee value.

One of the most important challenges in the twenty first century is population transition and aging.Various disease incidences in elderly people is a cause for using more drugs than youths and average adults and then show more side effects. pharmacokinetic changes and pharmacy dynamic in adulthood cause cardiac output decrease ,liver, kidneys, haemostatic changes, drug interventions and using OTC drugs case increasing drugs side effect in adults. Since drug use is different with other people, then Cockeroft-Gault method is a proper method for measuring drug dose and administration interval in adults. According to this formula at first we should evaluate the ideal IBW to height for both men and women and then certify adult creatinine clearance based on age, weight and serum creatinine concentration and then will certify dose fraction (DF) considering regression line, drug dose use level is made from DF into drug use in a usual state. Drug interval usage is certified from division of drug interval on DF in a usual state. This formula is a proper method for drug prescription in adults. Formulas, tables, and charts used are available in the context.

On the international arena, countries are seeking increased power and exerting influence over other countries in order to impose their own wills over them only to get to their intended interests. Sometimes, this struggle of power takes on a harsh face, and evolves into a total war. Having this in mind, the scientists of politics and geopolitics have been making their efforts to determine the factors that generate power for countries, as well as measure the extent to which they have power in relation to each other, particularly in the field of military power, in which the result of the efforts made by the scientists has been the definition of various formulas for measuring the countries’ power including military power. This article tries, in the process of conducting fundamental-applied research, to study the formulas and the definitions presented for measuring power in addition to using the library resources, and to establish, by using the descriptive-analytical method, whether or not a country’ s power can be assessed in relation to another country by using those formulas in the real world. The researchers finally concluded that the available formulas are unlikely to carefully assess a country’ s power over that of another country, hense setting forth the following formula by referencing to the conducted researches: MP= UP. NP/100(AP+GP+SP+PP+RP+ARP+HFP)+NW± WW+NDT+NWG

Background& Purpose: IOL power calculation is one of the current problems in cataract surgery. This study was performed to evaluate the accuracy of six IOL power calculation formulas in patients undergoing senile cataract surgery.Patients & Methods: This was a clinical trial on 61 eyes in 58 patients with senile cataract.All eyes underwent uncomplicated phacoemulsification or extracapsular cataract extraction and posterior chamber intraocular lens (PCIOL) implantation.Final refraction was performed 6 months after surgery; absolute refractive error was calculated as observed error minus expected error. Eyes were divided into three groups regarding axial length: <22mm, 22-24.5 mm and >24.5mm. Results were analyzed using the ANOVA and LSD tests.Results: Out of 58 cases, 32 subjects (55.0%) were male and (45.0%) were female. Patients age ranged from 35-80 y (mean 65±11.2 y) overall mean absolute error was 1.09±0.67 and there was no significant difference among the six formulas. In eyes of short axial length SRKI yielded better results in terms of final absolute error (P<0.05) However in medium and long eyes no significant difference was observed among the six formulas.Conclusion: Overall, the mean absolute errors of the six formulas were similar. We suggest that the choice of IOL calculation formulas should be based on availability, familiarity and simplicity; a higher level of caution should be considered in short eyes.
