Nowadays a large and growing field of health psychology, researchers do point out, any logical reason for the establishment of a psychosomatic patient. This study examined the Evaluation of Kyphosis in Mazandaran University of Science and Technology students and its relation to psychological factors. The method used in this research is descriptive correlation method is implemented. Population study of boys and girls were 56 (31 boys and 25 girls) and who had kyphosis has voluntarily participated in this study. The spinal mouse was used to measure the kyphosis angle and for its assessment of the patient's spine-concept, depression and anxiety are better examples of MMPI-2RF questionnaire (Reconstruction form of Minnesota Multidimensional Personality Questionnaire) (α=0.84), test Beck Depression Inventory (α=0.85), and test anxiety or Spielberger's (α=0.87), were used. The results showed that using the Pearson correlation coefficient between self-concept (r=0.52; P=0.13), depression (r=0.54; P=0.41), and anxiety (r=0.34; P=0.28), and no significant correlation with kyphosis (p<0.05). The results showed that the student alone kyphosis indicative of anxiety, depression and self-concept is not sick but creates kyphosis is related to other social and environmental factor. The results showed that in patients with kyphosis alone is not an indication of mental disorders but should be considered in the treatment of patients with these abnormalities to psychological factors.

The aim of the current research was to examine the effect of 12 weeks of correctional exercises on body image and social anxiety in students with lordosis disorder. Statistical society of research includes boy university students in master's degree level of Mazandaran University of Science and Technology. The research sample includes 30 boy university students and has been selected randomly and voluntarily and has been divided into two groups of test and control. To gather data, we have used multi-dimension relations of a self-body questionnaire and social agitation questionnaire. The method of research is tested in the pre-test, post-test kind, and by the control group. The result of variance analysis showed there is a meaningful difference between experimental group and control group. It means, reforming practices are influential on improving body image and social agitation.

The javelin throw is a track and field event, which is of very great antiquity. The most important goal in the javelin throw is the throwing record. In the javelin throw, three factors (initial velocity 1 V , initial throw angle 1  and initial throw height H) play a fundamental role in an athlete's record. Throwing record only depends on these three factors, but of course each of them alone is subject to various factors at the time of throwing: the place, time, environmental and physical conditions of an athlete. In this study, these factors were expressed, analyzed and investigated, and the physical, technical and computational parameters with greater precision (from the perspective of sports engineering) were also expressed, and thus the optimum modes for each of them were obtained. The initial throw velocity (V1), initial throw angle (θ1), initial throw height (H), their roles in throwing record and the technical parameters affecting them have been investigated. Results show that the equations of optimum modes were obtained for the three aforementioned variables. Depending on a series of specific initial values for each athlete, an optimum mode of initial velocity, initial angle and initial height of throw were obtained for each athlete, resulting in the maximum record for throwing.

in the present study, the pedigree and genotype data of 94 individuals were examined for accuracy of parentage allocations and identity test using 12 fluorescent-labelled microsatellite markers in a highly sensitive and accurate ABI system. The panel of 12 markers showed mean PIC value of 0.71 and Shannon index of 1.65 and 7.58 alleles per locus, which suggests that these markers are highly polymorphic and could be useful for parentage control. Based on scoring allele sizes, a total of 91 alleles were observed within the studied population. the highest and lowest number of alleles was observed for tgla227 locus and tgla126 and Bm1818 loci, respectively. the pedigree was considered incorrect in seven (35%) out of all the evaluated progeny, as their genotype did not match their parents. Combined EP value obtained for all loci in both parentage and identification analysis was 0.99, which indicates the high efficiency of the studied marker set and the accuracy of genotyping in ABI systems. Finally, the present findings confirmed the importance of surveying the pedigree structure and efficiency of 12 fluorescent-labelled microsatellite markers in a single multiplex pcr for parentage testing in the sampled holstein cattle population. key words: parentage testing, microsatellite, holstein cattle, pedigree, multiplex pcr, exclusion probability Per capita milk consumption in Iran has been reported to be 73 kg while the average world figure is between 300 and 350 kg. Holstein cattle are the dominant industrial breed for providing main dairy products in Iran.
