Background: Tension and migraine headaches are the most prevalent types of headaches. Some emotional and psychological factors are associated with these headaches. Objectives: To elucidate the nature of individual differences in emotion regulation and repetitive negative thinking among patients with tension headaches and migraine and compare it with normal subjects. Materials & Methods: In this cross-sectional, comparative study, the participants consisted of patients with tension headaches and migraine referring to the two neurology clinics in Isfahan City, Iran from 2019 to 2020. A diverse sample of patients (n =240) completed the difficulties in emotional regulation scale and perseverative thinking questionnaire. The Chi-square tests, Fisher’s exact test, GLM (generalized linear model), Tukey post hoc test, and LSD (least significant difference) test were used to analyze the obtained data in SPSS V. 21. Results: The results indicated that patients with a high level of repetitive negative thinking reported increased difficulties in emotional regulation and impulse control, limited access to emotion regulation strategies, and lack of emotional clarity (P<0.05). Moreover, the tension headaches group showed a higher level of difficulties in emotional regulation and repetitive negative thinking than the migraine and control groups (P<0.001). Conclusion: Weak emotional regulation and repetitive negative thinking are associated with migraine and, especially tension headaches. Therefore, therapeutic plans based on emotion regulation and thinking problems should be considered as a complementary and necessary treatment for these types of headaches.

Land suitability classification is important in planning and managing sustainable land use. Most approaches to land suitability analysis combine a large number of land and soil parameters, and are time-consuming and costly. In this study, a potentially useful technique (combined feature selection and fuzzy-AHP method) to increase the efficiency of land suitability analysis was presented. To this end, three different feature selection algorithms-random search, best search and genetic methods-were used to determine the most effective parameters for land suitability classification for the cultivation of barely in the Shavur Plain, southwest Iran. Next, land suitability classes were calculated for all methods by using the fuzzy-AHP approach. Salinity (electrical conductivity (EC)), alkalinity (exchangeable sodium percentage (ESP)), wetness and soil texture were selected using the random search method. Gypsum, EC, ESP, and soil texture were selected using both the best search and genetic methods. The result shows a strong agreement between the standard fuzzy-AHP methods and methods presented in this study. The values of Kappa coefficients were 0.82, 0.79 and 0.79 for the random search, best search and genetic methods, respectively, compared with the standard fuzzy-AHP method. Our results indicate that EC, ESP, soil texture and wetness are the most effective features for evaluating land suitability classification for the cultivation of barely in the study area, and uses of these parameters, together with their appropriate weights as obtained from fuzzy-AHP, can perform good results for land suitability classification. So, the combined feature selection presented and the fuzzy-AHP approach has the potential to save time and money for land suitability classification.

Background:The prevalence of anxiety disorders among children and adolescents are found to be approximately between 8–12 and 5–10, respectively, and the long-lasting effects of such disorders can expose the sufferers to impairment and dysfunction in several areas of life the examples of which are poor educational performance, low self-esteem, and depression. The present study aims to evaluate the efficacy of internet-based, cognitive-behavioral therapy (ICBT) in treating the anxiety disorders among adolescent females.Materials and Methods:The sample included thirty girls aged between 10 and 18 years suffering from a variety of anxiety disorders, under pharmaceutical therapy and referred to clinics of child and adolescent psychiatry specialists in Isfahan. The sample was selected through diagnostic interviews by psychiatrists based on the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision; afterward, they were randomly assigned to either the experimental or the control groups. To evaluate the efficacy of an ICBT in reducing anxiety disorder symptoms, Screen for Child Anxiety Related Emotional Disorders questionnaire was administered among the patients both before and 4 weeks after the treatment.Results:The covariance analysis results aimed to compare the anxiety disorder score variations between the two groups which demonstrate the fact that anxiety disorder scores in these two groups differ from one another (P < 0.001).Conclusions:This study is comprised of two Conclusions.the significant reduction in the mean of anxiety disorders scores in the experimental group compared to those in control group can be indicative of the efficacy of ICBT. In addition the significant reduction in the average of anxiety disorders symptoms’ scores according to the type of anxiety disorders in the experimental group, compared to those in control group, can be indicative of the efficacy of ICBT.
