The purpose of this study was to determine the effect of teaching life skills on dare and accountability of Imam Khomeini naval academy’s cadets. The statistical population of this study included all students of this university during the academic year 1995-94. This research is a pre-test and post-test design with control group. In the sample selection, a randomized cluster sampling method has been used. So, out of 220 students who participated in the dare and accountability tests as a sample of the company, 30 of them who received less scores in these tests were as a statistical sample. 15 of them were randomly assigned in the control group and 15 in the experimental group. The participants of the experimental group participated in 8 sessions of life skills training. However, no educational intervention was conducted for the control group. At the end, both groups were re-evaluated and the results of multivariate covariance analysis (MANCO) showed that life skills training had a significant effect on the level of dare α = .01 (F = 250.026) and student accountability (F = 79.82, α = .01).

The statistical population of this applied research includes 724 logistics and commodity experts in Marine Industries Organization. The simple random sampling method was used and the minimum sample size was 252 with Cochran formula. The instrument for collecting data was a questionnaire that its content validity was confirmed by the experts and academic professors. The construct validity was verified through confirmatory factor analysis. Data analysis and hypothesis testing were performed using SPSS software and structural equation method. The results of the research showed that customer pressure and innovation have a positive and significant effect on the sustainability of supply chain management. Also, a significant contribution to innovation education plays a special role in the share of education in innovation and supply chain management.
