In the past years, the use of steel structures with Saddle (khorjini) beam to column connections was one of the common construction methods in Iran. But the behavior of steel buildings with this type of connection in earthquakes such as Manjil 1369 and Bam 1382 showed the failure of connections before the failure of beams and columns. Considering the advantages of this connection, if new details and proper performance are provided, The Saddle connection can be used as a suitable connection in modern steel structures. For this purpose, in this paper, a new rigid saddle connection with reduced beam sections (RBS) for earthquake-resistant steel structures is presented. In the rigid saddle connection, two beams pass continuously on both sides of the column and are connected to the column by vertical plates. The RBS method has disadvantages such as local buckling of the web and lateral torsional buckling, to avoid these weaknesses and improve the performance of the connection, diagonal stiffeners were used in the beam web. Three laboratory samples were made and tested using IPE 140 profiles. According to the results obtained from these experimental tests, it was found that the sample with a reduced cross-section can withstand a rotation of 0.06 radians and the sample with stiffeners can withstand a rotation of 0.07 radians without any significant drop in the strength, which shows that both connections have an acceptable performance considering the Requirements of the AISC standard, and are placed in the category of rigid connections that can be used in the special moment frame systems. Also, the use of diagonal stiffeners increases energy dissipation and plastic rotation capacity of the connection.

The current research attempts to study the effectiveness of cognitive-behavioral group therapy on self-control, self-Restraint, and Dysfunctional Attitude in individuals with substance abuse. The research method was quasi-experimental with pretest-posttest, follow-up, and control group design. 34 patients referring to Tolou Medical Center which is located in Lorestan Province were selected in 1398 based on the Convenience Sampling and were randomly divided into the experimental and control groups. In data collecting, Tanji, Banister, and Bon Self-Control Questionnaire (SCS), Weinberger & Schwartz self-Restraint Scale (SRS), and Weissman and Beck’s Dysfunctional Attitude Scale (DAS) were used. Data analysis based on Covariance Analysis demonstrated that there are significant differences between the post-test scores of self-control, self-restraint, and dysfunctional attitude between the control and experimental group. 18% self-control, 39% self-restraint, and 75% dysfunctional attitude can be interpreted by the cognitive-behavioral method. These findings show that cognitive-behavioral therapy can lead to an increase in self-control and self-restraint and a decrease in dysfunctional attitudes in drug abusers. Therefore, therapists can use this therapy as an interventional method.

In recent years, banks have been affected by a number of market developments: deregulation, liberalization, globalization and various innovations, each of which affects the competitive conditions of banks. Just as bankschr market power plays a role in their profitability, so does competitive behavior affect financial soundness and stability. Competition and a healthy market structure are important in social welfare, in other words, low prices, low interest rates and good loans to consumers and companies,including small and medium-sized investment companies.Banks are considered as the key institution of the money and capital market in the process of economic development of any country, and the continuous economic growth of a country is impossible without considering the market structure of such an institution. On the other hand, assessing the degree of market power of the banking system is very important. In this study, the level of competition in the banking system of 52OIC countries from 2004  to 2019 has been estimated using GMM method. For this purpose, the Boone index has been used. In the first stage, the Boone index has been calculated and in the second stage, the effect of this variable along with the variables of deposit ratio, capital adequacy, non-current receivables, central bank assets in the econometric model has been studied.The Z-SCORE profitability index is also used to measure stability. The results of the Boone index show that these are short-term trends at all times, in all cases. Findings also show that among the variables under study, Non- performing loan raito have the greatest effect on banks  profitability. In addition, the relationship of all variables except Non- performing loan raito and profitability is positive and significant, so that their growth increases the profitability of banks. Finally, the results indicate that the two variables of Bonn index and banking stability also affect the profitability of banks.

In this paper, a generalized lambda distribution is proposed followed by Lorenz, Bonferonni and Zenga curves. Also, inequality indices and Hierarchical Lorenz curve are given based on this distribution. Moreover, according to securities and exchange organization of Tehran income data, we compare some parametric Lorenz figures with their Hierarchical form based on the generalized lambda distribution.
