Despite large amount of empirical evidence in support of rumination as a risk factor of depression onset and chronification, theoretical foundations of ruminative thinking are still being discussed. This includes the issue of so-called constructive, or reflec¬tive, ruminations. Objective: This study gives a theoretical review of different views on rumination, empirically tests the idea of constructive and non-constructive rumi¬native thinking, and tests the validity of the Ruminative Response Scale (RRS, Rus sian version) [38]. Study design: We conducted a factor analysis of adapted RRS, as well as an intercorrelational analysis of this scale, Symptom Checklist-90-Revised (SCL-90-r), and the COPE Inventory; hypotheses were tested in a general population group (n=476) and two clinical groups (patients with depressive disorders, n=53, and patients with different diagnoses with recent suicide attempts, n=41). Results: Our theoretical review examines ruminative thinking as a dysfunctional coping strategy (E. Watkins) from the perspective of the structural-dynamic model of thinking in the course of creative problem-solving (V. Zaretsky, A. Kholmogorova). Rumination is conceptualized as getting stuck «in a loop» at certain levels of organization of cognitive processes, which substitutes motivation focus on actual problem solving. The resulting four-factor structure of RRS has good psychometric properties and strong correla¬tions with different psychopathological symptoms and dysfunctional coping strategies (namely, psychological and behavioral avoidance and venting negative emotions); these correlations are found in all resulting factors but one, which implies that it may have a special status. Conclusion: The Russian version of RRS shows good preliminary psychometric characteristics and is viable for practical purposes. The idea of construc¬tive rumination discussed in literature has not been confirmed empirically. ¬

Clinical Referral

Achenbach and Edelbrock teacher and parent checklists were used to develop a practical procedure to assist educators in determining if a boy with behavioral/emotional dysfunction in elementary school requires mental health referral or SED evaluation. SED, psychiatric outpatient, and general population Caucasian boys ages 6 to 11 years were compared. Appropriately, scores for the SED and the outpatient groups were pathological and significantly greater than scores for the general population group on both checklists, while SED scores were significantly higher than outpatient scores on the teacher checklist. Logistic regression analyses showed the Total Problem scales of both checklists to be the most efficient and economical scales for classification. Finally, probability tables were constructed to distinguish SED and outpatient boys from general population boys, and SED boys from outpatient boys.

The Impact

A depressive disorder is a serious mental problem characterized by feelings of anxiety and sadness. Depressive disorders have increased from year to year, where the total number of people living with depression in the world is 322 million, this is supported by WHO 2017 data. Generally, someone in a depressed state experiences feelings of sadness, anxiety, or emptiness, and the impact that is caused if depression is not treated immediately, it will have an impact on oneself such as low self-esteem, social isolation, and even suicide attempts. Besides that, it will also have an impact on the people around it. The purpose of this study is to know the description of the level of depression in prisoners in Class II A Penitentiary in Bulukumba Regency in 2020. The research design used in this study is a descriptive research design with a cross-sectional approach. The affordable population in this study were inmates with all cases totaling 194 people with a sample size of 85 respondents. The sampling technique using a systematic random sampling method selects a sample from the population systematically. Data were collected using a questionnaire sheet. Based on the results of the research conducted, it was shown that the frequency distribution of the level of depression of the 85 prisoner respondents experienced mild depression as many as 64 respondents (75.3%) then moderate depression was 14 respondents (16.5%) and 7 respondents (8.2%) were not depressed. In all cases, the depression level of prisoners in class II A prisons in Bulukumba district experienced mild depression. Researchers suggest that further the sample size can be added so that data collection is more accurate and can be linked to other variables that can cause depression

Objectives: Obstructive sleep apnoea (OSA) may be more common in people with schizophrenia compared to the general population, but the relative prevalence is unknown. Here, we determine the relative prevalence of severe OSA in a cohort of men with schizophrenia compared to representative general population controls, and investigate the contribution of age and body mass index (BMI) to differences in prevalence. Methods: Rates of severe OSA (apnoea–hypopnoea index > 30) were compared between male patients with schizophrenia and controls from a representative general population study of OSA. Results: The prevalence of severe OSA was 25% in the schizophrenia group and 12.3% in the general population group. In subgroups matched by age, the relative risk of severe OSA was 2.9 ( p = 0.05) in the schizophrenia subjects, but when adjusted for age and BMI, the relative risk dropped to 1.7 and became non-significant ( p = 0.17). Conclusions: OSA is prevalent in men with schizophrenia. Obesity may be an important contributing factor to the increased rate of OSA.

We investigated the design of a neural-network-based adaptive control system for a smart structural dynamic model of the twin tails of an F-15 tail section. A neural network controller was developed and tested in computer simulation for active vibration suppression of the model subjected to parametric excitation. First, an emulator neural network was trained to represent the structure to be controlled and thus used in predicting the future responses of the model. Second, a neurocontroller to determine the necessary control action on the structure was developed. The control was implemented through the application of a smart material actuator. A strain gauge sensor was assumed to be on each tail. Results from computer-simulation studies have shown great promise for control of the vibration of the twin tails under parametric excitation using artificial neural networks.
