Authors: Vlasova V. N. , Vlasov S. N. 
Published: October 2024

Introduction. Pregnancy and childbirth have a profound impact on a woman. These events are a normal life crisis that is present in most women and results in a dramatic loss of a sense of stability. During this period, the restructuring of a woman’s personality is based on psychological patterns similar to those of normal mental development. Thus, pregnancy acts as a biological prerequisite for the change in her life. From the point of view of the empirical psychological component, the specificity of meaning-life orientations and values in women in connection with childbirth is quite diverse, but little studied.Objective. To study changes in meaning and value orientations in women during the period from the stage of pregnancy planning to the beginning of motherhood.Materials and methods. In the course of the study we used: the test “Meaning-Life Orientations” by D. A. Leontiev (SZHO method); the method “Value Orientations” by Sh. Schwartz (adapted by V. N. Karandashev). Methods of statistical data processing were used with the help of R program to calculate Student’s t-criterion to study the reliability of differences in data between stages.Results. There are reliably significant differences in the meaning and life orientations of women preparing for pregnancy and women who have already given birth. The specificity of prevailing value orientations differs in women preparing for pregnancy and in women who have already given birth. The values of women preparing for childbirth are dominated by such values as “power”, “achievements”, and “stimulation”, while the values of women who have already given birth are higher on the scales of “universalism” and “conformity”.Discussion. The study revealed that the complex of value and meaning-life orientations is significantly transformed in women during pregnancy and after childbirth, which causes the transformation of the system of values in relation to themselves, the child and the surrounding reality. Based on the results obtained, it is possible to develop and implement a set of measures aimed at adopting a new system of values and lifestyle of women during the first stages of motherhood.

Published: October 2024

Introduction. This article explores the relationship between the attitude towards uncertainty and the nature of personality adaptability in the context modern life situation’s risks. The relevance of this topic lies in the possibility of choosing not only constructive, but also destructive adaptation schemes in situations of uncertainty, which are increasingly arising in the lives of young people today. The analysis of studies existing in this subject field made it possible to identify a number of subjective predictors of a successful adaptation. The novelty of this research is identifying and describing the influence of the attitude towards uncertainty on the adaptation of an individual in the context of modern risks. The contents of the article include analysis of various adaptation profiles and their link to the attitude towards uncertainty.Purpose. Studying the relationship between the attitude to tolerance and adaptation of an individual in the context of modern risks.Materials and Methods. This study features the following methodological tools: the McLean Uncertainty Tolerance Scale; the S. Maddy Resilience Test (adapted by D. A. Leontiev); the methodology for diagnosing socio-psychological adaptation (K. Rogers and R. Diamond); the “Attitude to Uncertainty” questionnaire (T.N. Shcherbakova). Statistical data processing was carried out using the Spearman rank correlation coefficient.Results. A structured analysis of the factors that determine the adaptability of students and teachers in different regions in the context of modern risks is presented in this section. The peculiarities of the severity of indicators of tolerance to uncertainty and resilience of an individual, as well as their relationship with adaptability – maladaptivity were found.Discussion. The results of the empirical study reflect the importance of the attitude and tolerance of an individual to uncertainty for their successful adaptation. For the first time, the interrelation of the components of resilience and tolerance to uncertainty with adaptability – maladaptiveness of students from different regions personalities in the context of information, social and educational risks are shown. Thus, it can be said that there is a connection between the adaptability of students’ personalities and their attitude to uncertainty, indicators of tolerance to rapidly changing conditions, and the severity of the parameters of resilience. The level of reflection of the features of the projections of uncertainty allows to develop resilience and increase the level of adaptability to the relevant life conditions on a personal level. A model of a program of psychological support for increasing the level of adaptation of students in the context of modern risks of uncertainty is proposed.

Introduction. The article is devoted to the study of a set of factors leading to voluntary self-isolation of young people in Russia. A number of foreign studies have documented voluntary withdrawal from social life and the desire for complete social isolation among young people. This phenomenon was first described in Japan and labeled as “hikikomori”. Many of the hikikomori did not have mental disorders to explain their reclusiveness, and therefore a comprehensive biopsychosocial model of the formation of such maladaptive behavior was proposed.Objective. To test the causal relationship between social exclusion, nervous system characteristics, and attachment type in members of the hikki and dead inside subcultures.Materials and Methods. Sixty-eight people (48 women and 20 men) participated in the study. Of them, the conditional norm was 36 people, 20 were dead inside, and 12 were hikkas. To assess the peculiarities of the nervous system we used express-diagnostics of the nervous system types on the basis of J. Streliau’s method of temperament diagnostics; to study the attachment types we used the method “Self-assessment of the generalized type of attachment” adapted by T. V. Kazantseva; to study child-parent relations we used the author’s questionnaire. Correlation and regression analysis were used as methods of statistical data processing.Results. The study confirmed the biopsychosocial model of social isolation, which is the result of nervous system features interrelated with the formation of relationships with parents and attachment type, which in turn is related to the formation of relationships with peers.Discussion. According to the results of the study, it was found that the predictors of social reclusiveness of hikikomori are increased excitability of the nervous system, which turns any social contacts into painful ones, while the representatives of dead inside, on the contrary, experience too weak reactions to external and internal stimuli, which also affects social adaptation.
OVERCOMING DUALISM: THE IMPORTANCE OF CONSOLIDATING LAW AND REGULATION TESTING IN INDONESIA
Authors: Wardana Dodi Jaya 
Published: October 2024

This article highlights the significance of unifying the testing of all laws and regulations under the authority of the Constitutional Court in Indonesia. Currently, the testing of laws and regulations is divided between two state institutions, namely the Constitutional Court and the Supreme Court, resulting in dualism in the evaluation of laws and regulations. Through a normative-juridical approach, examining existing laws and theories, this article reveals that the dualism of testing laws and regulations is a problem that needs to be addressed. The problem arises from the differences in decision outcomes between the Constitutional Court and the Supreme Court. The two institutions employ different benchmarks for material testing, with the Supreme Court relying on legislation and the Constitutional Court drawing on the 1945 Constitution of the Republic of Indonesia. The importance of unifying the testing of all laws and regulations lies in the fact that the unintegrated testing system causes confusion, creates institutional conflicts between the Constitutional Court and the Supreme Court, and results in a lack of synchronization between laws and regulations from lowest to highest. Therefore, it is essential to conduct integrated testing of all laws and regulations, with the Constitutional Court serving as the authority responsible for this task. Notably, an increase in the number of Constitutional Court judges is necessary to achieve better development of laws and regulations testing in the future.

OBJECTIVE: To examine whether there was a racial disparity among Medicare beneficiaries in the likelihood of using outpatient physical therapy (PT) services following a hip fracture. METHODS: Our retrospective descriptive cohort study analyzed administrative claims data for 51 781 Medicare beneficiaries post hip fracture. We examined the association between race and PT use within the first 6 months post fracture using hierarchical logistic regression, adjusting for demographics, medical complexity, and socioeconomic factors. We used Poisson regression to examine the association between race and the number of PT visits. RESULTS: Only 31% of beneficiaries used outpatient PT after hip fracture with significant racial disparities. After controlling for demographics, medical complexity, and socioeconomic factors, Black beneficiaries had 42% lower odds of using PT (adjusted odds ratio [aOR], 0.58; 95% confidence interval [CI]: 0.51, 0.66) compared to White beneficiaries. Among PT users, Black beneficiaries received fewer visits than White beneficiaries (rate ratio [RR], 0.85; 95% CI: 0.82, 0.88) with this disparity persisting after adjustments (RR, 0.88; 95% CI: 0.85, 0.91). CONCLUSION: Even after adjusting for demographic, medical, and socioeconomic factors, Black beneficiaries were less likely to use outpatient PT following hip fractures. Conditional on an initial PT evaluation, Black beneficiaries received fewer sessions. J Orthop Sports Phys Ther 2024;54(12):776-782. Epub 9 October 2024. 10.2519/jospt.2024.12641

Гексанитрогексаазаизовюрцитан современный продукт, обладающий высокими значениями плотности и энтальпии образования, а также оптимальным кислородным балансом. Для обеспечения максимальной эффективности применения продукта необходимо добиться получения идеальных кристаллов СL-20 без внешних и внутренних дефектов, определенного полиморфного и гранулометрического состава. Такие важные показатели как форма кристаллов, дисперсность, а также гранулометрический состав продукта CL-20 закладывается на стадии кристаллизации. Полученные в результате кристаллы, неоднородны, имеют форму отличную от сферической - с острыми вершинами и выраженными гранями, а также значительную дефектность (сростки, раковины, трещины, сколы, выбоины) и широкое распределение частиц по размеру. Указанные характеристики закладываются на стадии кристаллизации CL-20, что делает ее одной из ключевых при синтезе нитрамина. В статье представлены результаты улучшения кристаллографической модификации кристаллов CL-20 при помощи гидромеханической окатки продукта в окатывателе, а также разработано разделение полидисперсного продукта на узкие размерные фракции, используя метод гидравлической классификации. В результате работы были установлены, условия проведения процесса окатки, а также условия эффективности метода гидроклассификации. Полученные результаты подтверждены ИК- и КР- спектроскопией.
Hexanitrohexaazaisowurtzitane is a modern product with high density and enthalpy of formation, as well as optimal oxygen balance. To ensure maximum efficiency of the product, it is necessary to obtain ideal crystals of CL-20 without external and internal defects, a certain polymorphic and particle size distribution. Important indicators such as the shape of the crystals, dispersion, as well as the particle size distribution of the CL-20 product are laid at the crystallization stage. The resulting crystals are heterogeneous, have a shape different from spherical - with sharp peaks and pronounced faces, as well as significant defectiveness (splices, shells, cracks, chips, potholes) and a wide distribution of particle size. These characteristics are laid at the crystallization stage of CL-20, which makes it one of the key in the synthesis of nitramine. The article presents the results of improving the crystallographic modification of CL-20 crystals using hydromechanical pelletizing of the product in the pelletizing agent, and the separation of the polydisperse product into narrow size fractions using the hydraulic classification method is developed. As a result of the work, the conditions for the rolling process and the conditions for the effectiveness of the hydroclassification method were established. The results are confirmed by IK and KR spectroscopy.
