Loneliness and death anxiety are two basic psychological problems experienced by the elderly, and well-being therapy is an intervention that can be effective in this case. This study aimed to evaluate the effectiveness of well-being therapy on loneliness and death anxiety in the elderly.
This was applied research conducted as quasi-experimental with pre-test, post-test, and follow-up with a control group.The statistical population of the study included all elderly people aged 65 to 85 years living in Neshat daily nursing home in Mashhad, 30 of whom were randomly divided into an experimental group and a control group. The members of the experimental group participated in the weekly well-being therapy sessions and no intervention was done in the case of the control group. The Russell, Pilau, and Ferguson (1978) Loneliness Scale and the Templer Death Anxiety Scale (1970) were used to collect data. Data analysis was performed using SPSS software version 26 and two-way repeated measures ANOVA.
The findings showed that the comparison of the adjusted means of loneliness and death anxiety scores in the post-test and follow-up stages increased compared to the pre-test stage.The interactive effect of time × group on the loneliness component (p=0.0001, F=124.70) and on the death anxiety component (p=0.0001, F=119.70) was significant at the level of 0.01.
Well-being therapy can significantly reduce feelings of loneliness and death anxiety in the elderly as a non-pharmacological treatment.

Substance abuse disorder has an increasing negative implication in all societies. Psychological treatments are helpful in reducing this disorder. The aim of this study was to compare the effectiveness of Dialectical Behavior Therapy and Compassion Focused Therapy on blood cortisol levels and self-control in drug abusers.

The research method was quasi-experimental. The statistical population of the study included all men with substance abuse in the Bozorgmehr clinic of Torbat-e-Heydariyeh in 2018, 60 of whom were selected by available sampling method and were randomly assigned to two experimental groups and a control group. The experimental group was trained for 10 sessions of 90 minutes, but the control group did not receive any training. To collect data, self-control questionnaire and vitro serum levels of cortisol, were used. The data were analyzed using Mancova in spss 24 software.

The results showed that there was a significant effect on self-control and cortisol levels in two groups of Dialectical Behavior Therapy (p = 0.001). However, according to the mean difference, the effectiveness of Compassion Focused Therapy on two self-control variables and cortisol levels was higher than Dialectical Behavior Therapy.

Psychological treatments such as interventions applied in this study can help to treat substance abuse disorder. Therefore, considering the low cost and effectiveness of these treatments, it is recommended to use them in the treatment of substance abuse.

This study was aimed to investigate the effectiveness of cognitive behavior therapy integrated with mindfulness on pain and pain catastrophizing in patients with breast cancer.

In this clinical trial study, a semi-experimental, pre-post-test, and control method was used. Twenty-four patients with breast cancer from Omid Hospital of Mashhad were selected via purposive sampling method and randomly assigned with permutation blocks in two groups of intervention (N= 12)and control (N= 12). The groups were assessed by perceived pain and pain catastrophizing scale before and after the intervention. Participants in the intervention group received mindfulness integrated with cognitive behavior therapy for 8 weeks. Data were analyzed using multivariate analysis of covariance.

The results showed that the intervention group had a significant decrease in perceived pain and catastrophic pain (P> 0.05).

According to the results, it can be concluded that using the behavior of integrated therapy with mindfulness has been effective in reducing pain and catastrophizing pain in breast cancer patients. Therefore, it can be a perfect complement therapy for patients with breast cancer

Since the lifetime of a satellite is generally limited by the amount of fuel, reducing its fuel consumption is especially important. To reduce geostationary satellite fuel consumption, it is necessary to select a thruster con- guration, which, in addition to satisfying all attitude control system (ACS) requirements (such as producing torques in all directions, and modifying the orbital inclination and radius osets), minimizes fuel consumption during the liquid apogee motor (LAM) maneuver. In this paper, after dynamic modeling, simulation of the satellite control is undertaken in three control laws: the direction cosine matrix, Euler angles and quaternion. All simulations were performed using MATLAB. By comparing these three control schemes, the best control law is selected for use in simulation of the studied con gurations. On the other hand, control with thrusters has some complexity because of their inherent characteristics, such as minimum pulse width, valve opening and closing delays, the ability to generate force only in one direction and the uncertainty in the nominal thrust. We have included the thruster speci cations in the actuator model in our control simulations. Finally, after introduction of requirements for an acceptable con guration, by conducting several simulations, parameters such as fuel consumption and attitude control accuracy for a number of dierent con gurations, consisting of eight or six thrusters parallel to the main axes of the satellite, have been computed and compared. In conclusion, con gurations with minimum steady state error, with minimum fuel consumption and con gurations that minimize fuel consumption and steady state error, together, have been introduced.The results of this paper can be used for determination of the optimum con guration of thrusters in design of the ACS system of geostationary satellites.
