Authors: Miranda Sabrina Coutro , Da Silva Júnior Manoel Cláudio , Salles Leandro Almeida
Published: April 2022

O Cerrado rupestre é a comunidade vegetal que ocupa afloramentos de arenito e quartzito. Este é ainda encontrado em bom estado de conservação principalmente devido ao acesso relativamente restrito   maioria de suas áreas. Ocorre na Serra Dourada - GO onde foi objeto do presente estudo na Estância Quinta da Serra (16o 02ââ?¬â?¢ 01ââ?¬Â S e 50o 03ââ?¬â?¢ 41ââ?¬Â W) que visa avaliar a fitossociologia e a estrutura diamétrica do seu componente lenhoso. Para o inventário permanente foram aplicadas 10 parcelas de 20 x 50 m para a avaliação dos indiví­duos com Db30cm ââ?°¥ 5 cm, inclusive os mortos em pé. Foram encontradas 54 espécies de 43 gêneros e 25 famí­lias. O H= 3,13 nats.ind-1, equalibilidade Jââ?¬â?¢=0,79, Chao 1= 66 e Chao 2 = 63 espécies refletem a alta diversidade florí­stica na amostra. A densidade total foi 1.137 ind.ha-1 e a área basal total foi 7,085 m2.ha-1.  As espécies mais importantes foram Andira vermifuga Mart. Ex Benth, Qualea parviflora Mart., Wunderlichia crulsiana Taub., Anacardium occidentale L. e Heteropterys byrsonimifolia A. Juss. A comparação com a fitossociologia de outras 23 áreas de cerrado sentido restrito no Brasil Central, em diferentes classes de solos, estudadas com o mesmo método, ressaltou diferenças florí­sticas e estruturais entre as áreas. A distribuição dos diâmetros indicou a tendência auto-regenerativa para a comunidade, onde 96% dos indiví­duos apresentaram Db30cm < 15 cm. O maior Db30cm foi de 41,06 cm anotado para um indiví­duo de Caryocar brasiliense Cambess. O pequeno crescimento em diâmetro parece ser uma das limitações impostas aos indiví­duos nestes ambientes. Os indiví­duos mortos ââ?¬Å?em péââ?¬Â representaram apenas 2,2% da densidade total, 2,3% da área basal total e ocorreram em 70% das parcelas, o que salienta o estado de conservação da vegetação local. O cerrado rupestre estudado é composto por 21 (38,9%) espécies amplamente distribuí­das no Bioma, é portanto, fonte potencial de sementes e propágulos para recuperação de áreas degradadas  em diferentes classes de solos na região.

Cognitive mistakes of codependents as a way to protect against uncertainty
Authors: Artemtseva Natalia G. , Malkina Malkina A.
Published: April 2022

The paper is devoted to the problem of studying the inner subjective world of a codependent personality. Despite the active scientific studies of the phenomenon of codependency in recent years, there is still room for new ideas in this area. The problem under study is interesting and relevant both for psychological science in general, and for practical and consulting psychology. The purpose of the study presented in the paper is to identify cognitive mistakes inherent in individuals with actualized codependency. Codependency is considered not only as being close to a dependent relative, but more broadly as a set of certain patterns of thinking and behavioral characteristics. As a result of the study, the severity of certain cognitive errors in codependent subjects was found. Cognitive errors of thinking that are present both in the group of actualized codependents and in the group of non-actualized codependents are revealed. When comparing the indicators of the severity of cognitive errors in codependent men and women, a general trend of the presence of cognitive errors was found: in actualized codependents, the indicators of men and women do not differ, and in non-actualized codependents, almost all cognitive errors are significantly more pronounced than in men. It is shown that cognitive errors aimed at avoiding uncertainty prevail in people with actualized codependency. It is concluded that the cognitive errors identified in codependents are not just associated with a state of uncertainty, but can also be a way to protect against it. The results of the research can be used in the development of therapeutic strategies for correcting the manifestations of codependency through awareness and correction of cognitive mistakes.
Socio-psychological research of value orientations of students
Authors: Chernyshova Evgeniia L. , Ivanov Dmitry V. , Roschupkina Ekaterina I.
Published: April 2022

The analysis of philosophical, sociological, pedagogical and psychological literature let us make a conclusion that the fundamental basis of the legal consciousness of each person is the degree of his spiritual perfection and maturity. Value and spiritual and moral prerequisites, in turn, are the basis of law, making the behavior of an individual in society expedient. The authors of the paper focus their attention on the frequent cases of delinquent behavior among young students. There is a new form of delinquent behavior, that is deviant socio-political activity. The authors of the paper see the problem of contradiction between the real state of legal consciousness of students and the lack of knowledge of the relationship of legal consciousness with individual psychological characteristics and value orientations of students. The desire to find ways to resolve this contradiction determined the purpose of the research conducted to investigate the relationship of legal consciousness with individual psychological characteristics and value orientations of Samara students who took part in unauthorized protest actions in January 2021. The paper presents the results of an empirical study of individual psychological characteristics and value orientations of students who took part in unauthorized protest actions. The results received, it was found that the subjects of the sample are really prone to delinquent behavior, they have a low level of volitional control of the affective sphere, a pronounced tendency to aggression and violence against the background of negative attitudes towards social norms and rules, the level of legal awareness is low, a positive attitude to law is not formed, and higher, spiritual values are rejected. Among the preferred values are the values of the hedonistic and gloric vector.
A Dual-Radio Hybrid Mesh Topology for Multi-Hop Industrial IoT Networks in Harsh Environments
Authors: ÇELEBİ Hasari
Published: April 2022

Industrial Internet of things (IIoT) is a paradigm that changes the way people interact with infrastructures by enabling ubiquitous connection to the Internet. It allows to design connected infrastructures in industrial environments, e.g., factories, in order to support innovative services and improve efficiency. While the advantages of IIoT are numerous, it has some fundamental issues such as propagation of signal through metallic obstacles, i.e., walls in industrial environments. To address this issue, we propose a hybrid wired-wireless mesh node and network topology called hybrid mesh network (HMN), enabling the signal to cross over the metallic obstacles in harsh environments. The proposed hybrid mesh node utilizes dualradio feature of IEEE 802.11 Wi-Fi standard to improve the performance of the proposed HMN further considering multihop communications. The effects of the packet size and different fading channels on the performance of the proposed HMN are investigated through various simulations. In addition, the performance of the proposed HMN is compared with that of conventional wireless mesh network (WMN). The results reveal that the proposed HMN outperforms conventional WMN and the proposed topology is promising for the implementation of high performance wireless mesh networks in harsh environments.

At the same time, at present one can observe a sharp increase in adverse outcomes of delivery, up to intrauterine death and fetal asphyxia, resuscitation of newborns and other consequences in women who refuse vaccination. The works of transnational research teams on the need to separate an infected mother and a weak newborn, to stop direct feeding, to stay together for a long time in kangaroo mode are presented. Most researchers believe that the probability of vertical transmission of the virus from mother to fetus is low and the risk of infection of the newborn is associated mainly with caregivers. Foreign studies of psychological problems of pregnant women and delivered women are presented. A huge layer of problems of the psychological well-being of an infected young mother, as well as healthy pregnant women against the background of the pandemic, is being is introduced.
