Abstract-The present study is conducted among 283 students from University of Zabol to identify the harm and ethical and social issues in the field of information technology and to classify the immoral practices that students are doing in this field. First various important issues in the field of IT in the social and ethical areas are discussed. Then the cases considered as the most commonly used immoral activities, are selected for evaluation, and the participants ranked these activities according to the method presented in the questionnaire. These activities are examined and analyzed descriptively by SPSS program, reliability of the questionnaire is measured by Cronbach's alpha coefficient, Bartlett Test of Sphericity and KMO index and the validity of the results is verified using T-test and the results are ranked based on the first performance that happens frequently and the last performance that happens rarely or never. Finally, a set of strategies are presented for preventing ethical abuse in the field of Information Technology so that the challenges are reduced.

“…The Kaiser-Meyer-Oklin value, wh ich is a measure of the sampling adequacy, was .931, a value that greatly exceeded the minimu m reco mmended value of .60[see [50][51][52]. The Bartlett's Test of Sphericity [53] for this pool of crime-reporting items also reached the statistical significance of p < .000, which tells us that the analyses supported the elements that contributed to the results of the correlation mat rix[see 54,55]. In other words, the relationships between items in the scale were statistically significant.…”

The purpose of this study is to determine whether or not prior victimizat ion, along with socio-economic status affect people's willingness to report crimes to authorities. This study is limited to addressing the effect of prior v ictimization on willingness to report crimes by 1) the type of victimizat ion (i.e., being a v ictim of property crimes or a victim o f crimes against persons), 2) being a vict im of a crime, regardless of the type of crime versus not being a victim, and 3) the difference in crime-report ing variation between the two. The findings of this research study are based on the analyses of the data that have been collected through a self-admin istered survey questionnaire distributed to 531 undergraduate university students. Overall, the findings that emerged fro m this study suggest that prior victimizat ion cannot be considered a good predictor of crime -reporting behavior.

“…The validity of the questionnaire is measured by using Bartlett Test of Sphericity [11] and KMO 1 index [12] which is shown in Table 2. In this study, Bartlett Test of Sphericity is significant at a significance level of 0.05 because significance P <0.05 and also the KMO value is desirable.…”

Abstract-Intellectual property rights (IPR) of computer software is the right to assign the software to its creator, not limited to time and space, and non-transferable. Proving IPR of the creators of computer software requires a rigorous review of the ways in which these rights may be violated. The present study was conducted by comparing two populations in Iran with the aim of identifying the level of familiarity and observance of software IPR: 1) 96 software engineers member of IEEE Association and 2) 386 students randomly. Results are analyzed by SPSS software and the validity of the results is verified using T-test. By comparing the results, it was concluded that the first population significantly observed these cases more. Then a model was presented for protecting software IPR so that the challenges are reduced. This research is the completion of our previous work that was discussed as a future work.
