One of the factors that can be the link between our intentions AND actions AND their external consequences is human agency, which indicates the conscious design AND intentional execution of actions by the individual in order to influence future events.Objective AND Method: This research with a developmental approach of psychometric method AND method 1, examines the psychometric indices of the Human Factor Characteristics Scale using the classical theory of test score measurement AND the graduated question-answer theory. The purpose of this study, which included high school students in Tehran, was selected by cluster sampling of 500 people as a sample size AND statistical analysis was performed on 481 data. To collect the data, the ion Human Agent Characteristics Scale (2011) was used AND the research questions were evaluated using IRTPRO AND SPSS software.Results:The assumption of local independence based on Pearson x2 index was established by applying Simjima's calibrated question-answer theory AND the assumption of being one-dimensional based on the analysis of multidimensional question-answer theory. Diagnosis parameters with question-answer approach AND classical approach Test score Both item 25 approach had the lowest AND item 2 had the highest diagnosis parameter. The answer thresholds for all the questions were so far apart that no option was covered by the other option, AND the options were independently selected by individuals at intervals of theta. The total scale was calculated with Cronbach's alpha of 0.945, intentionality of 0.894, foresight of 0.780, self-reactivity of 0.871 AND rethinking of 0.762. Also, the role of each item in internal consistency was investigated by the loop method, which all questions had a favorable role in internal consistency of this scale. The value of the validity coefficient obtained from the question-answer theory was obtained by marginal method for intentionality 0.92, forethought 0.85, self-reaction 0.91, rethinking 0.83..

Tumor detection AND isolation in MAGNETIC resonance imaging (MRI) is a significant consideration, but when done manually by people, it is very time consuming AND may not be accurate. Also, the appearance of the tumor tissue varies from patient to patient, AND there are similarities between the tumor AND the natural tissue of the brain. In this paper, we have tried to provide an automated method for diagnosing AND displaying brain tumors in MRI images. Images of patients with glioblastoma were used after applying pre-processing AND removing areas that have no useful information (such as eyes, scalp, etc.). We used a bounding box algorithm, to create a projection for to determining the initial range of the tumor in the next step, an artificial bee colony algorithm, to determine an initial point of the tumor area AND then the Grow cut algorithm for, the exact boundary of the tumor area. Our method is automatic AND extensively independent of the operator. comparison between results of 12 patients in our method with other similar methods indicate a high accuracy of the proposed method (about 98%) in comparison s.

Sound is one of the forms of mechanical energy AND the two main characteristics of sound are intensity or power AND frequency or wavelength of sound.their performance against the incoming sound wave, industrial silencers can be divided into two general groups of resonating AND absorption silencers, the main difference between these silencers is the release of sound energy from the channeling system, which is one of the common examples of the use of resonating type silencers, their use in It is the internal combustion engines that distinguish absorption silencers from the resonator type based on the fact that the main AND visible part of the act of muting the sound is achieved by changing sound energy to heat energy.The goal of this article is to design a muffler based on the breaking of sound frequencies resulting from the movement of fluid in the exhaust output of vehicles, which leads to a reduction of at least 50 db of sound AND gives the operator enough peace AND concentration. In this article, after examining three types of mufflers, absorbent mufflers that use the PROPERTIES of porous absorbent MATERIAL to absorb passing sound AND are the simplest form of mufflers, have been selected, analyzed AND reviewed AND are suitable for the OM457 engine of Idem Industrial Company. It designed for maximum inlet exhaust temperature is 520 AND for the maximum kW power is 315 with the maximum discharge relative pressure of 185 mbar for homogenization with the stANDard atmosphere.

The surface condition AND microstructure of near stoichiometric (Fe823Ndll.8B5.9) Nd-Fe-B alloy ribbons AND the effect of melt spinning parameters were investigated using optical, scanning AND transmission electron microscopes (SEM, TEM). The formation of gas pockets on the roll surface of the ribbons during melt spinning can prevent heat transform AND result in local coarse grains. The local thickness would also be less in these places AND thus perforates preferentially during ion beam milling. Therefore different areas of the sample should be carefully observed in the TEM. Reducing inert gas pressure in the chamber will eliminate the gas pockets. As a general trend, decrease in the ribbon thickness AND mean Nd2 Fe14B grain size were observed on increasing the roll speed. By careful adjustment of the melt spinning parameters, the nanostructure will develop. An orientation relationship was found between Nd2 Fe14B AND α-Fe precipitates for coarse grain samples melt spun at low roll speed. Dark field image of such grain also shows that some of these α-Fe precipitates have the same orientation. X-ray diffraction evident the development of texture by decreasing the roll speed.

The Big Five Inventory (BFI) is one of the most widely used personality questionnaires, but very few studies have been conducted on its psychometric PROPERTIES in Iranian population. This study was carried out with the aim of studying the psychometric PROPERTIES of the BFI questionnaire. For this purpose, 390 university students in Tehran (210 girls AND 180 boys) with an age range of 18 to 56 years (M = 27.52; SD = 8.79) were selected using the convenience sampling method AND completed BFI AND NEO-FFI questionnaires. Cronbach's alpha, multitrait-multimethod matrix, AND confirmatory factor analysis were used to estimate the psychometric PROPERTIES of the questionnaire. The result of the confirmatory factor analysis showed that 15 of the 44 items did not have a strong factor loading (higher than 0.40) on the corresponding factors AND were therefore removed from the questionnaire. The fit indices showed that the Persian version of 29 questions (BFI-29) with 5 factors has a good fit with the data. The reliability analysis also showed that the range of Cronbach's alpha coefficients of the factors is from 0.70 to 0.79. The lowest Cronbach's alpha coefficient was related to agreeableness factor AND the highest was related to conscientiousness. The findings from the multitrait-multimethod matrix showed that the BFI-29 questionnaire has good convergent AND divergent validity with the NEO-FFI questionnaire. In general, based on the results of the present study, it can be said that the BFI-29 questionnaire has desirable psychometric PROPERTIES AND whenever a short tool for personality measurement is needed, this questionnaire can be used.

Background AND Aims: Disc displacement is the most common temporomANDibular joint disorder AND MAGNETIC resonance imaging (MRI) is the gold stANDard in its diagnosis. This disorder can lead to changes in signal intensity of MAGNETIC resonance (MR). The purpose of this study was evaluation of correlation between relative signal intensity of MR images of retrodiscal tissue, superior AND inferior head of lateral ptrygoid muscle with type of anterior disk displacement AND condylar head flattening in patients with temporomANDibular disorder (TMD).MATERIALs AND Methods: In this retrospective study, 31 MR images of patients who had anterior disc displacement were evaluated. After relative signal intensity measurement for retrodiscal tissue, superior AND inferior head of lateral ptrygoid muscle, the correlation between relative signal intensity AND type of anterior disc displacement was evaluated with repeated measure ANOVA test. In each of these 3 areas, t-test was used to compare the groups with AND without condylar head flattening.Results: The correlation between relative signal intensity of MR images AND type of anterior disc displacement in retrodiscal tissue, superior AND inferior head of lateral ptrygoid muscle was not significant. There was also no statistically significant correlation between relative signal intensity of MR images AND flattening of condylar head in retrodiscal tissue, superior AND inferior head of lateral ptrygoid muscle (P>0.05).Conclusion: According to findings of this study, relative signal intensity of MR images in retrodiscal tissue, superior AND inferior head of ptrygoid muscle is not a good predictor for type of anterior disc displacement AND flattening of condylar head. It seems that this cannot be used as a diagnostic marker for TMD progression.
