Abstract. This study investigated the effects of electromagnetic field radiated from mobile phones with frequency between 500 to 900 MHz on some biochemical parameters in 60 swiss albino mice which divided in three groups (one control and two tests). Test groups were exposed to electromagnetic wave twice a day for 20 and 40 days. Blood samples were prepared from heart and Total Protein, Albumin, Blood Urea Nitrogen (BUN), Creatinine Phosphokinase (CPK), Cholesterol, Creatinine, Glucose, Alanin Amino Transferase (ALT), Aspartate Amino Transferase (AST), Alkaline Phosphatase (ALP), Amylase, Lipase, Thyroid Stimulating Hormone (TSH), T3 and Tyroxin (T4) were measured and statistically analysied. According to the results, long time electromagnetic field radiation caused a significant decrease in serum creatinine, glucose, total protein, albumine, cholesterol, T4 and body weight. The amount of Serum BUN, CPK, ALP, ALT, AST, TSH and T3 significantly increased. Electromagnetic radiation has influence on biochemical parameters in mice and may effected on healthy.

The current research was conducted with the aim of the efficacy of training life skills on the Payame Noor students' self esteem, Saghez branch. The research population includes all the Payame Noor students, Saghez branch who were studying in the educational year of 2013-2014. In this research 40 students were selected through the random sampling method available as the research sample volume. From among this number, 20 students were selected through the random sampling method available as the research sample volume who was participating in the educational workshop of life skills and 20 more students were also chosen as the control group. The method applied in this research is semi empirical with two groups of experiment and control. The experiment group was placed under 8, 120 minute sessions of training life skills. To collect data the 58 item Cooper Smith questionnaire was used. To analyze data, the descriptive statistics (Average, standard deviation,…) as well as inferential statistics (covariance analysis) were applied . Results indicated that the average self esteem scores in the experimental group posttest is higher than that of the posttest in the control group.
