Background and Objective: Increasing industrial activities associated with the production of pollutants, including heavy metals, is one of the main causes of water and soil pollution. Mineral activities are one of the human activities that cause pollution of the natural resources such as soil. Method: In this study, the zoning concentration of copper as soil contamination around Meyduk copper mine was investigated. The direction samples were taken according to the situation of surrounding villages. Systematic sampling of 360 samples had been collected through the directions. Measuring the concentration of sample was done using atomic absorption method in the laboratory. To indicate the degree of soil pollution with heavy metals, Muller’ s geoaccumulation index was used. Finally, in order to estimate the normal concentration of Cu and pollution of soil, Kriging method was used. Results: Results showed that the maximum amount of Cu concentration is 697. 5 mg/kg and the minimum is 6. 35 mg/kg. The Cu concentration trend in direction D was more than direction M due to the direction of local dominant wind. Discussion and Conclusion: By receding from location of mine, the overall trend of Cu concentration decreased. This indicated the role of mine activities on soil pollution.

Background and Objective: The main goal of this research was “ The Relationship between Personnel’ s Blood Lead Concentration Parameter, Job Stress and Job-Burnout Parameters in Staff of a Battery Manufacturing Company” . Method: It was a descriptive and cross sectional investigation. The sample group (with age range 20-65) included 100 out of 200 staff who worked in the productive lines of company. They were selected randomly. Job Stress (Davies, 1991) and Maslach Job-Burnout (1981) questionnaires were used as tools. Also the lead concentration of whole blood was determined by using atomic absorption spectrometer. Findings: The results of Pearson correlation test showed that there are significant relationship between blood lead concentration with depersonalization and low performance of staff (P<0. 01, P<0. 05). There are significant relationship between stress related to jobs and job-burnout dimensions (P<0. 01). The results revealed that blood lead and job stress can predict depersonalization and weak performance of staff. Discussion and Conclusion: Many workers are in the exposure of chemical hazards like lead concentration simultaneously they are suffering from job stress and different types of pressures because of hard conditions of job in a battery manufacturing companies. These difficult conditions can lead them towards job-burnout (depersonalization and weak performance) too. It was recommended to the managers and engineers to control dust and fumes of lead pollution with respect to occupational health and safety in the workplaces. The management plans should be targeted the job related stress management and prevention of job burnout as well.

Sistan and Baluchestan province has 1. 4% of GDP and occupies the 19th position in the country. Meanwhile, the province's GDP per capita in comparison to the country has a significant difference. In this pape, in order to measure the multiplier, the input-output table approach has been used by flagg's spatial contribution method. Examining the contribution of forward and backward linkage as well as the results of multipliers, dispersion and sensitivity factors show that 12 fields of economic activity have a coefficient of diffusion power and high dispersion sensitivity. on the other hand, the average cost of households in the province is 65 percent of the average cost of households in the country, and this indicates the low welfare of households in the region.

The most important medium through which human beings can form relationships and connections is using different methods such as speaking, writing and sign language. The point that deaf or semi-deaf people are ignored in communities is because of their disability in forming intimate relationships, and also the lack of common training''s according to what is needed in the society. The present study seeks to design a system that receives spoken language as an input and changes it to Farsi sign language after all the necessary normal language analysis is done. The challenges on our way are: a) number of sign language words which are few compared to the words in spoken language and b) the ambiguity and pun normally used in Farsi language. So, common systems architecture could not be applied. Therefore, an architecture is introduced in which Farsi to sign language translation system performance is improved and accuracy and practicality are reinforced through removing pun modules and changing inputs in ways applicable to the world of the deaf applying the related ontology.
