What Kind of Knowledge- Skillagricultural Education Instructors Need in the Training Program?

Abstract: The purpose of this study was to examine teachers’ current and desired knowledge and skills related to curriculum and instruction. The population for the study was 1214 students of agricultural schools in the west of Iran (Hamedan and Kermanshah Provinces). A systematic randomization resulted in a sample of 398 participants from the population. A survey questionnaire was constructed and used to collect data from randomly selected students and were analyzed by SPSS software. Based on the results of the test and Cohen's effect size in comparison t-test with a significance level of 0.05, the agricultural education teachers in three levels - professional skills in order to provide the innovative curriculum and training by a factor of (C.d. =2.00), the use of educational technology in lessons coefficient (C.d. =1.54), scientific methods of assessment and evaluation multiplier effect (C.d. =1.41) are moderate to low

Utility of Restriction Spectrum Imaging Among Men Undergoing First-Time Biopsy for Suspected Prostate Cancer.

OBJECTIVE. The purpose of this article is to evaluate restriction spectrum imaging (RSI) in men undergoing MRI-ultrasound fusion biopsy for suspected prostate cancer (PCa) and to compare the performance of RSI with that of conventional DWI. MATERIALS AND METHODS. One hundred ninety-eight biopsy-naïve men enrolled in a concurrent prospective clinical trial evaluating MRI-targeted prostate biopsy underwent multiparametric MRI with RSI. Clinical and imaging features were compared between men with and without clinically significant (CS) PCa (MRI-ultrasound fusion biopsy Gleason score ≥ 3 + 4). RSI z score and apparent diffusion coefficient (ADC) were correlated, and their diagnostic performances were compared. RESULTS. CS PCa was detected in 109 of 198 men (55%). Using predefined thresholds of ADC less than or equal to 1000 μm2/s and RSI z score greater than or equal to 3, sensitivity and specificity for CS PCa were 86% and 38%, respectively, for ADC and 61% and 70%, respectively, for RSI. In the transition zone (n = 69), the sensitivity and specificity were 94% and 17%, respectively, for ADC and 59% and 69%, respectively, for RSI. Among lesions with CS PCa, RSI z score and ADC were significantly inversely correlated in the peripheral zone (ρ = -0.4852; p < 0.01) but not the transition zone (ρ = -0.2412; p = 0.17). Overall diagnostic accuracies of RSI and DWI were 0.70 and 0.68, respectively (p = 0.74). CONCLUSION. RSI and DWI achieved equivalent diagnostic performance for PCa detection in a large population of men undergoing first-time prostate biopsy for suspected PCa, but RSI had superior specificity for transition zone lesions
