One of the most principal operations in many PKCs is Modular Exponentiation (ME). This operation is usually performed by successive modular multiplications. So, the efficiency of these PKCs is released on the efficiency of the Modular Multiplication (M2) and modular exponentiation implementation. Therefore, it is essential to minimize the execution time of the M2 and the number of required M2 for performing the ME operation. This paper proposes a novel ME algorithm. In the developed algorithm, the Bit Forwarding (BF) and multibit-scan-multibit-shift techniques are employed for the performance improvement in the ME operation. The complexity analysis is accomplished to show that the developed exponentiation algorithm has benefit in the number of required multiplications. The results indicate that the presented algorithm improves the results compared to other modular exponentiation algorithms by about 11%-85%.

One of the most common problems in marriage is Marital burnout and Conflict, which, due to the devastating effects on couples and family members, is considered necessary by family counselors and therapists. This study aims at addressing the Early Maladaptive Schemas in Female Nurseschr('39') Marital Conflict and Burnout.

It is correlational research. The target population includes all Female Nurses employed in hospitals in Zahedan during 96-97. One hundred nurses were selected via an available sampling method and completed Youngchr('39')s Schemas Questionnaire and Marital Burnout and Conflicts scale. Data were analyzed using the Pearson Correlation Coefficient and graded Multivariate Regression method.

Results indicates that Early Maladaptive Schemas of emotional deprivation (P = 0.01), mistrust/ abuse (P < 0.001), social isolation/ alienation (P < 0.001), defectiveness/ shame (P < 0.001), failure (P < 0.001), dependence/ incompetence (P < 0.001), vulnerability to harm or illness (P < 0.001), enmeshment self (P < 0.001), subjugation (P < 0.001), emotional inhibition (P < 0.003), self-discipline (P < 0.001) were positively related to Marital Conflicts. Also, emotional deprivation (P = 0.01), mistrust/ abuse (P < 0.005), social isolation/ alienation (P < 0.02), failure (P < 0.03), dependence/ incompetence (P < 0.03), vulnerability to harm or illness (P < 0.009), subjugation (P < 0.02), self- sacrifice (P < 0.007), emotional inhibition (P < 0.001), unrelenting standards (P < 0.02), entitlement (P < 0.02), self-discipline (P < 0.02) were positively related to Marital Burnout.

According to research findings, Early Maladaptive Schemas are positively related to Marital Conflicts and Marital Burnout and predict them. Hence, it is recommended to analyze the Early Maladaptive Schemas and offer tips to promote them to reduce Marital Conflicts and Burnout.

Aggression is one of the factors influencing the relationship of couples, so the purpose of this paper was to investigate the effect of marriage training based on the Gotman’s Model on covert relational aggression in women.

Using a randomized controlled trial design, among mothers of Behesht primary school students in Shahriar town in Tehran during 2018 year a sample including 30 women were selected on a voluntary basis and randomly divided in two experimental and control groups. The experimental group received the intervention and control group subjects remained in the waiting list. All subjects were evaluated by Nelson and Carroll’s covert relational aggression scale at the pre - test and posttest stages. Data extracted from the scale and analyzed by a ANCOVA analysis.

Data analysis showed that significant difference between the women of the two groups in terms of the extent in their covert relational aggression and the trainings reduced covert relational aggression in women of the experimental group.

The training of marital skills based on the Gotman’s Model could reduce the covert aggression of women and is then recommended to therapists.
