- چکیده انگلیسی: Iodine as a trace micronutrient has important role in body physiology and its sufficient intake is essential for synthesize and secrete adequate amounts of thyroid gland hormones which influenced all periods of human life including fetal, childhood and adolescence. The aim of this study was to evaluate iodine concentration in marketed edible salt samples in Lorestan Province, comparing with existing standards and offering solutions necessary to fix the probably problems. Two hundred and forty samples of 20 brands of marketed edible salt were purchased randomly of eight cities in Lorestan Province during April 2014 to March 2015. Iodine concentration was measured by titration method. Results showed that iodine concentration in 64.59% of salt samples was in acceptable limits according national standard of Iran during this study. A significant number of nonstandard samples showed violation of salt factories of regulations and their noncompliance to mandatory standards. Due to importance of iodine in human health and valuable role in the vital functions of the body at different periods of human life and to avoid violations of iodized salts manufacturers, regular control of marketed salts and enforcement of laws and regulations are recommended.aflatoxin production in treated nuts.

- چکیده:
- چکیده انگلیسی: Predicting the river discharge is one of the important subjects in water resources
engineering. This subject is of utmost importance in terms of planning,
management, and policy of water resources with the aim of economic and
environmental development, especially in a country like Iran with limited water
resources. Awareness of the relation between rainfall and runoff of basins is an
inseparable past of water design studies. Lack of sufficient data on rainfall-runoff
due to the absence of appropriate hydrometric stations reveals the importance
of using indirect methods and heuristic algorithms for estimating the basins'
runoff more than before. In the present research, the genetic programming
model has been employed to simulate the rainfall-runoff process of
Khorramabad River basin, and in order to introduce the patterns and identify the
best pattern dominating the nature of flow, all statistical data were divided into
two groups of training and experiment (52 percent training and 48 percent
experiment) and the program was implemented for 1000 replications using fitting
functions and going through replication and developmental processes so as to
find the optimal replication. Moreover, in order to evaluate the relations obtained
from the simulator model, Root Mean Square Error (RMSE) and Mean Squared
Error (MSE) indexes and Coefficient of Determination (R2) have been used. The
investigations demonstrate that the employed equation 3 has the greatest
relevance with the observational data. Therefore, it is recommended that the said
equation be used for the rainfall-runoff studies of the abovementioned basin.
Based on the results, the genetic programming model is an accurate direct
method for predicting the discharge of Khorramabad River basin.- انتشار مقاله: 04-09-1397

- چکیده:
- چکیده انگلیسی: Background: Because of the importance of community health and the growing need for health care Health organizations have expanded their scope and with an entrepreneurial approach seeking to upgrade their performance. Knowledge is the most important capital of organizations and key factor in economics. The purpose of this study was to investigate the effect of knowledge management on organizational entrepreneurship through learning capacity.
Methods: This research was an applied type, and in terms of method, it was a descriptive survey. The statistical population of the research was the Hospital health staff of Guilan province in 2016, the statistical sample estimated 370 by Morgan table. This research was conducted with three standard knowledge management questionnaires, organizational entrepreneurship and learning capacity with structural equation modeling and smartpls2 software. The reliability of the research tools were calculated Organizational Entrepreneurship 0.88, Knowledge Management 0.93, and Learning Capacity 0.85, respectively.
Results: Knowledge management 0.46 and organizational learning capacity have positive effect on organizational entrepreneurship. Also, knowledge distribution 0.94 and knowledge storage 90% and interaction with environment 0.84 and participatory decision-making 0.82 were identified as the most important factors of knowledge management and organizational learning capacity.
Conclusion: Managers are encouraged to pay attention to organizational learning capacity and knowledge management skills to increase organizational entrepreneurship. Improvement and attention to knowledge management and the expansion of organizational learning capacity can strengthen entrepreneurship. Therefore, health managers and policymakers should consider these issues.
