Estimation of contact lengths using deep learning neural network
Authors: POLAT Alper
Published: March 2023

One of the most common problems in engineering is contact problems. In recent years, researchers have turned to alternative methods that can offer effective solutions in a shorter time, instead of solutions containing complex and long mathematical expressions. This study focuses on the estimation of the contact lengths in a homogeneous elastic layer suppressed by two elastic punches with two solution methods. Firstly, a new model was designed for estimation using Deep Learning Neural Network (DNN), one of the deep learning structures. Estimation of contact lengths was provided with the output of the DNN model, which was fed with the homogeneous elastic layer, the ratio of shear modules of the punches and the input parameters of punch radii. The finite element method was used as the second solution method. The problem was modeled in the ANSYS programme and the solution was made with the same parameters used in DNN modeled. The results obtained from both solutions were compared with the solutions obtained by the theory of elasticity and classical NN in the literature. It had been seen that the results obtained with DNN and ANSYS were compatible with the results obtained with analytical and classical NN and the margin of error was smaller.

В статье представлены результаты изучения обычая помещать в могилу вместе с умершим части туши барана (овцы), зафиксированного в погребениях XIII-XIV вв. в Байкальском регионе. Рассмотрены материалы из трех районов, входивших в состав Монгольской империи (Юго-Восточное Забайкалье, Северное Прихубсугулье, Южное Приангарье). Дается описание захоронений, особое внимание уделяется бараньим костям, их составу и расположению в могиле. Отмечено, что для Южного Забайкалья характерно помещение в могильную яму в районе головы погребенного голени барана. Намного реже, чем берцовые кости, в захоронениях встречаются бараньи лопатки или позвонки. При этом последние чаще всего находятся под тазовыми костями погребенных или верхней частью бедренных. В Прихубсугулье голень барана клали возле руки или ноги умершего. В ангарских захоронениях фиксируется помещение в могилу головы барана и всей его спинной части, которые располагались в ногах покойника. Сделан вывод о том, что в захоронениях саянтуйского типа, распространенных в Южном Забайкалье и характеризующих погребальную традицию монголов имперского периода, преобладало помещение в могилу голени барана, которая располагалась вертикально. В других районах Байкальского региона фиксируются иные традиции в размещении частей туши барана в погребении, что, вероятно, связано с отсутствием в них монгольского населения и его элиты.

Authors: Barsante Moreno Pedro Christiano , Picoli Renata Palopoli , Gonçalves do Nascimento Debora Dupas
Published: March 2023

Objetivo: Analisar a aquisição de competências para a formação generalista previstas no Programa de Estágio Supervisionado em Atenção Primária à Saúde (PESAP) do curso de medicina de uma Universidade privada, na perspectiva dos alunos e dos preceptores. Método: Estudo seccional, descritivo-analítico, com 104 alunos e 16 preceptores, por meio de questionário autoaplicável contendo 60 questões, em escala tipo Likert, distribuídas nas áreas: atenção primária à saúde (n=9), saúde do adulto e do idoso (n=13), saúde da criança e do adolescente (n=28) e saúde da mulher (n=10). Calculou-se a média aritmética, desvio padrão e classificação (incipiente, parcialmente satisfatória ou satisfatória). Resultado: Das competências relacionadas à atenção primária à saúde, 66,7% receberam classificação satisfatória para ambos os participantes. Para a saúde do adulto e do idoso, 53,8% das competências foram satisfatórias por alunos, e 61,5% por preceptores. No tocante à saúde da criança e do adolescente, 13 competências (46,4%) foram adquiridas satisfatoriamente, na ótica dos alunos e 9 (32,1%), dos preceptores, e na saúde da mulher, 4 (40%) e 5 (50%) competências receberam classificação satisfatória para ambos, respectivamente. Obteve uma média satisfatória de 51,8% e 52,6% para os alunos e preceptores, respectivamente. Conclusão: Embora a maioria das competências previstas no PESAP foram adquiridas de forma satisfatória, a classificação final foi parcialmente satisfatória. O PESAP mostrou-se propício para as áreas Atenção Primária à Saúde e Saúde do Adulto e do Idoso. Porém, ainda existem lacunas a serem aprimoradas, principalmente em relação à saúde da criança e do adolescente e saúde da mulher.
Ansiedade infantil, família e profissionais de saúde bucal: vivências em odontologia
Authors: De Carvalho Thaís Cristina Rodrigues , Carvalho Leitão Biato Emília
Published: March 2023

A ansiedade presente nas crianças pode influenciar fortemente o seu modo de se relacionar com os profissionais durante as sessões odontológicas e pode estar ligada a diversos fatores, como experiências anteriores e até a ansiedade dos próprios pais. A ansiedade e o medo estão entre os principais elementos que dificultam o tratamento dentário, podendo possuir diversos fatores associados, como a idade e a origem cultural da criança, assim como as ações do dentista e a ansiedade familiar (em geral, das mães). O estudo teve como proposta refletir, por meio de um ensaio teórico, sobre os principais fatores relacionados à ansiedade da criança frente ao ambiente odontológico e, assim, auxiliar na relação profissional-paciente-família. Nesta reflexão, que partiu de uma leitura sobre as noções de vivências em Nietzsche e de acontecimento em Jacques Derrida, buscou-se articular tais conceitos a discussões e recomendações encontradas na literatura em Odontologia. O debate suscitado pareceu contribuir com elementos para a compreensão da subjetividade e a atenção à saúde no que diz respeito à ansiedade, bem como ao medo infantil, na atenção odontopediátrica.
The structure of the institutional model of formation of youth ecological culture: regional aspects
Authors: Tereshina M. V. , Miroshnichenko I. V. , Yakovenko N. V. , Yakovleva E. A.
Published: March 2023

Aim. To develop a justification of the structure of the institutional model for the formation of environmental culture of young people as a holistic structure that integrates the various actors in this process, as well as the available resources and implemented technologies to achieve the aims of sustainable regional development.

Material and Methods. The empirical justification of the proposed model was based on 14 focus group interviews conducted in the Krasnodar region in 2022 with representatives of young people, expert sessions with representatives of institutional structures involved in the implementation of practices to form the ecological culture of young people (12 expert sessions), online questioning of young people (sample size 1600 respondents). The case-study method was used to analyse eco-oriented practices in the field of youth and educational policy.

Results. The authors identified and characterised the main subjects involved in the formation of the ecological culture of young people, the set of technologies used (information and communication, game and project) and the resources and principles that determine the effectiveness of environmental education and educational practices. The authors propose a structure of the institutional model of the process and the results of formation and development of youth ecological culture, revealing its cognitive, value, emotional and activity components in the context of sustainable regional development.

Conclusion. The universal nature of the structure of the proposed model allows us to extrapolate the main results in the system of pedagogical support of the development of youth ecological culture in the activities of educational providers, as well as creating a basis for their institutionalisation in the activities of the executive authorities and bodies working with young people, not only in the Krasnodar Territory but also in other regions of the Russian Federation.
The climatic signal in tree rings of the common oak (Quercus robur L.) on the south-eastern border of its range in the Ural River basin, Russia

Published: March 2023

Aim. The objective of this study was to identify and analyze the climatic signal contained in the tree-rings of common oak on the southeastern border of its range in Russia (Ural River basin).

Material and Methods. The materials for the study were tree-rings in samples of common oak wood from three sites in the southern part of the Dziau-tyube ridge. Measurements of ring-width were performed on the MBS binocular microscope and on the Lintab measuring complex with the TSAP-WinTM software package. The construction of tree-ring chronologies was carried out in the ARSTAN program. Dendroclimatic analysis was carried out in the R package treeclim.

Results. The limiting climatic factors for the radial growth of the common oak on the southeastern border of its range are precipitation during the winter-spring season and the initial period of vegetation and to the greatest extent with the precipitation in March-May. It was shown that the strength of this climatic signal in oak tree rings was not constant over time. The dynamics of this signal are characterized by the presence of local periods of decline, the beginning of which is timed to the years of mass gypsy moth outbreaks.

Conclusions. Since the beginning of the 1980s, there has been a significant decrease in the relationship of radial growth with the amount of precipitation for March-May. The reason for this change, in our opinion, could be a strong change in the condition of trees and stands caused by the consistent impact of strong oak defoliation caused by Gypsy moths and late spring frosts.
Russian-Kazakh transboundary water bodies: typology, dynamics, economic significance
Authors: Padalko Yu. A. , Chibilev A. A.
Published: March 2023

The issues related to transboundary reservoirs in the state border zone of the Russian Federation and the Republic of Kazakhstan are analysed and their typology is articulated. Issues concerning the legal definition of the concept of "transboundary water body" in the legislation of the two countries are outlined. As a result of comparative decoding of differenttime images of remote satellite sensing of the earth, border sections where the course of rivers change were identified.

Aim. To analyse and classify transboundary water bodies on sections of the state border of Russia and the Republic of Kazakhstan and identify problematic situations.

Material and Methods. The study of these transboundary water bodies was carried out on the basis of both the analysis of interstate agreements on the delineation of the border of the Russian Federation and the Republic of Kazakhstan, the use of cartographic methods and the analysis of retrospective satellite images.

Results. Inconsistencies in the level of legal definition of the concept of "transboundary water body" in the legislation of the two countries are shown. Transboundary water bodies on the state border of the Russian Federation and the Republic of Kazakhstan have been identified and classified. Based on a retrospective analysis of satellite images, problematic situations arising from changes in the location of water bodies as a result of channel deformations of transboundary rivers and fluctuation of lakes have been identified.

Conclusions. According to the results of this work, all waterbodies located in the state border zone along its entire length have been identified. A typology of these has been carried out and the length of boundary watercourse sections has been established. Using the example of the transborder Ural River, the situation of the section of the river along which the state border lies is shown with an analysis of the changes in the channel and their dynamics.

Authors: Nemati Mohadeseh , Danesh Pouya Fahima , Roshani Asl Elmira , Rasmi Yousef
Published: March 2023

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new coronavirus named by the International Committee on Taxonomy of Viruses. COVID-19 patients have high mortality due to respiratory failure from acute respiratory distress syndrome (ARDS) induced by SARS-CoV-2. The abnormal activation of P21-activated kinase (PAK1, RAC/CDC42-activated kinase 1) is reported in COVID-19. The PAK1 induces nuclear factor kappa B (NF-κB) activation as well as inflammatory pathways through its stimulation. BAY 11-7082 {(E) 3-[(4-methylphenyl)-sulfonyl]-2-propenenitrile is one of the therapies that inhibit inflammation via mentioned signaling pathway, therefore, we suggest that this drug can potentially be effective in treating COVID-19.
Integrity and Confidentiality of Data Protection on Consumers' Privacy in Tanzania: A Case Study of TCRA
Authors: Abduel Mishael , Magingila Kulwa
Published: March 2023

In a world struck by advanced technology in all information and communication parameters, confidentiality and data protection of consumers are vital. However, organisations in diverse business aspects find it challenging to protect consumers' privacy; hence consumers' confidence in business declines. This study focuses on the integrity and confidentiality of data protection on consumers' privacy in Tanzania using TCRA as a case study. The study employed a qualitative approach and a case study design. The researcher preferred purposive sampling, and primary data were collected from 10 respondents who were interviewed. In addition, the study collected qualitative data that were analysed through content analysis. The results of this study revealed that trustworthiness, honesty and responsiveness play a significant role in the integrity and confidentiality of data protection that consequently influences consumers' privacy. Therefore, the study recommends that the government formulate and implement the personal data protection Act. Also, the study recommends reviewing the regulations to include emerging issues in technology like the Internet of Things (IoT), blockchain, big data and social networks.
Entrepreneurial Acumen and Financial Literary of Self-employed Rural Mothers
Authors: Pabelona Rechie B.
Published: March 2023

The purpose of this study was to evaluate the financial literacy and entrepreneurial prowess of rural mothers who work for themselves. One hundred fifty eight (158) self-employed rural mothers made up the study's sample. Self-employed rural mothers were found to have low interpersonal skills and low levels of critical and practical thinking skills, with mean scores of 2.37 and 2.61, respectively, and moderate levels of entrepreneurial skills in terms of personal characteristics and practical skills, with mean scores of 2.89 and 3.41 and 3.41 and 2.89 respectively. In terms of actual financial knowledge and self-perceived financial knowledge, the respondents' levels of financial literacy are both ambiguous, with means of 3.2036 and 3.5048, respectively. It is highly advisable to take short-term courses like the training that DTE provides to all SMEs regarding managing a business. Financial literacy and entrepreneurial skill have a strong association. It shows that there is a strong correlation (r =.251*) between self-perceived financial knowledge and actual financial knowledge. The level of association between self-perceived financial knowledge and business acumen was then quite strong (r =.554**).  Finally, there is a strong correlation (r =.539**) between actual financial knowledge and entrepreneurial skill. This result demonstrates that there is a great need to raise the financial literacy of rural mothers who work for themselves. Governments, academia, and those in the financial industry should collaborate to create a better financial future for rural women who work for themselves as well as for the nation as a whole. The link discovered should be further supported by future study.

Escepticismo, falibilismo y certeza : una reflexión en torno a Wittgenstein
Authors: Faerna García-Bermejo Ángel Manuel
Published: March 2023

En La voluntad de creer, William James proponía una sencilla taxonomía de posiciones epistemológicas (2003, p. 153). Los «dogmáticos» creen que se puede alcanzar alguna verdad, mientras que los «escépticos» lo niegan. A su vez, los primeros se subdividen en dos grupos: los «absolutistas», que sostienen que cierto tipo de creencias llevan el sello inconfundible de su propia verdad, y los «empiristas», que piensan que ninguna creencia verdadera se puede identificar de manera infalible. Podríamos reformular estas cuatro opciones en los siguientes términos: • (a) Los antiescépticos («dogmáticos») opinan que hay casos en los que una persona tiene derecho a decir que sabe algo. De ellos, —(a1) los infalibilistas («absolutistas») opinan, además, que hay casos en los que una persona tiene derecho a decir que sabe algo con certeza, mientras que —(a2) los falibilistas («empiristas») opinan, en cambio, que nunca se tiene derecho a decir que se sabe algo con certeza. • (b) Los escépticos opinan que nunca se tiene derecho a decir que se sabe algo (ni, a fortiori, que se sabe con certeza).
Religious instincts and the transformation of inquiry in Peirce's pragmaticism
Authors: Ward Roger A.
Published: March 2023

In this essay I begin by tracking the transformation of Peirce’s notion of inquiry from «The Place of Our Age» to «The Fixation of Belief» which lays the ground for pragmatism. I next trace the movement from pragmatism to pragmaticism via the role of instinct, and then conclude by showing how the content of Peirce’s religious faith and his instinctive love for the church and the reality of God shapes the telos of inquiry, a telos that is evident in the transformation of the inquirer, most poignantly described in «A Neglected Argument for the Reality of God».
Elección racional y adaptación : claves para una comprensión pragmatista de la acción
Authors: Orozco Contreras Richard Antonio
Published: March 2023

La teoría de la elección racional que dominó gran parte de la comprensión de la racionalidad especialmente en la primera mitad del siglo XX, y que tan valiosa ayuda ha prestado a las investigaciones en temas de economía y en temas de teorías de la decisión, ha sido, sin embargo, cuestionada cada vez más con una abrumadora evidencia empírica que demuestra su incapacidad para esclarecer la acción humana. Su nivel explicativo se presenta ahora tan ineficaz que es calificada de indeterminada (Elster, 1999) mostrando así su escaso valor empírico. La mayor fortaleza que exhibe es su capacidad para realzar el carácter normativo de la racionalidad. Cuando me refiero a dicho carácter estoy señalando el uso más común del concepto, tanto en ciencia como entre legos, es decir, usar la racionalidad como un estándar que determina qué acciones han cumplido los requisitos óptimos y cuáles no. Lo que ha permitido destacar la teoría de la elección racional es que las personas cuando definen una teoría científica, cuando deciden la contratación de un nuevo personal para la empresa o cuando realizan una apuesta podrán ser consideradas racionales siempre y cuando cumplan con una serie de requisitos procedimentales. Para tal fin ha sido de mucha utilidad la consideración de la utilidad máxima esperada así como la del costo mínimo esperado. Más adelante podré explicar estos conceptos y la manera en que iluminan la comprensión de la racionalidad de la acción humana. Todos estos logros teóricos han forjado, como dije, el uso más extendido del concepto de racionalidad —el normativo—, al punto tal que muchas discusiones, alrededor de mediados del siglo XX, giraban en torno a si era racional o irracional una elección o una decisión.

Conversaciones libres con los niños : el método clínico piagetiano. Relación entre teoría y método

Toda investigación asume una metodología y toda metodología está en relación con una teoría y con una orientación epistemológica implícita o explícita. Resulta mejor hacerla explícita, pues la elección de la metodología que se usará depende de la finalidad del problema que se está estudiando e inclusive, dentro de un mismo marco epistemológico, es imposible utilizar el mismo método para diferentes problemáticas.

Hace solo unos meses, la presidenta del Concytec —institución del Estado peruano dedicada a la promoción y difusión de la investigación científica en el país— envió un comunicado a los trabajadores del Consejo, en el que manifestaba su preocupación por la abundancia de símbolos religiosos en los diversos ambientes del local institucional y anunciando la prohibición de esas manifestaciones puntuales de fe en sus instalaciones. «Debemos impulsar el pensamiento crítico basado en la evidencia. Este es la piedra angular de la ciencia. He visto con preocupación la proliferación de imágenes religiosas en Concytec. Las que han aumentado al punto que visitantes extranjeros de diverso origen me han hecho sorprendidas reflexiones», advierte el mensaje de Gisella Orjeda, la presidenta del Consejo2 . «De lo dicho anteriormente se desprende que como institución de un estado laico e independiente de la Iglesia, que respeta todas las religiones, debemos mantenernos independientes de cualquier demostración religiosa en el ámbito institucional»3 . Esta medida no fue bien recibida por un grupo de empleados, que elevaron una queja al Arzobispo de Lima
Creencia, religión y agencia : las funciones de la religión en contextos plurales
Authors: Basterretxea Moreno Iziar
Published: March 2023

En este trabajo hemos tratado de analizar de forma empírica el alcance de la religión como factor, sea promotor o inhibidor, de desarrollo humano entendido como generación de capacidades que amplían las opciones de respuesta frente al medio; es decir, amplían la autonomía para decidir la vida que se quiere vivir. En concreto, nos hemos preguntado hasta qué punto las personas religiosas tienen un comportamiento cívico diferente a las no religiosas. Nos alejamos por tanto de la perspectiva institucional para intentar acercarnos al mundo de los seres humanos individuales. Ahora bien, ¿cómo podemos saber si quienes profesan una religión son más libres, se desarrollan más humanamente o son mejores ciudadanos que quienes no profesan ninguna?

El reconocimiento generalizado de la utilidad del foro para establecer lazos personales y de respeto mutuo entre representantes de instituciones que compiten entre sí en la arena política y social ha venido siempre acompañado de un cierto desconocimiento de sus modus operandi y una interrogante más o menos permanente sobre la eficacia de su contribución para poner en la agenda asuntos sustantivos e influir en las políticas públicas y, con mayor razón, para enfrentar significativamente problemas importantes de la sociedad peruana. Esta ponencia pretende cubrir hasta cierto punto esos dos déficits
Agencia, conflicto y desarrollo humano en Ayacucho : el caso de Sacsamarca post-Sendero Luminoso
Authors: Eskenazi Jael
Published: March 2023

El conflicto armado interno (CAI) se inicia en un contexto en el que, luego del fracaso de la Reforma Agraria que, con la creación de Sociedades Agrarias de Interés Social (SAIS) y de Cooperativas Agrarias de Producción (CAP), revirtió la tendencia principal a la parcelación de latifundios y avance de la economía campesina, se produce un repliegue del Estado en el campo (Degregori, 2003, p. 167). Este repliegue se agudiza con la crisis económica que, coincidentemente, se inicia en la segunda mitad de la década de 1970. En ese momento, varios de los poderes tradicionales también se habían visto resquebrajados y es así que distintos actores buscan aprovechar la oportunidad para tratar de cubrir los vacíos que se abrieron en el país
El reconocimiento de la sexualidad : la orientación sexual y la unión civil en el Perú
Authors: Barrientos Violeta
Published: March 2023

El reconocimiento de la sexualidad como parte de la dimensión humana es uno de los temas pasados por alto históricamente, al menos hasta que la sexualidad no apareciera como campo de estudio a inicios del siglo XX2 . La misma sexualidad fue considerada un tabú, materia perteneciente a la esfera doméstica, privada o hasta solamente como una función fisiológica del cuerpo. Las leyes que la regulaban se sustentaban, por lo general, en la moral y buenas costumbres o en principios de fe. Lejos estábamos aún de pensar que algún día los derechos y libertades sexuales iban a reclamar un lugar propio en la teoría política ciudadana y el derecho.

Las peticiones en quechua del curato de Chuschi (1678-1679)
Authors: Durston Alan
Published: March 2023

Presentamos aquí el conjunto de textos quechuas de autoría indígena más extenso que se conozca de la época colonial, con excepción del Manuscrito de Huarochirí. Se trata de nueve peticiones (un total de veinte páginas) presentadas en 1679 como parte de una demanda contra el cura de Chuschi por los pueblos de Chuschi, Choque Huarcaya, Auquilla y Tomanga2 . Sugerimos la hipótesis de que los escritores se valieron de quipus como fuente de información sobre las expropiaciones de dinero y bienes atribuidas al cura. En todo caso, estas peticiones provienen de un contexto en el cual se utilizaron los quipus a lo largo del período colonial y, en algunos casos, hasta el siglo XX: la auto-fiscalización interna de las comunidades indígenas (Salomon 2004). De forma más clara y directa, las peticiones de Chuschi son fuentes claves para comprender el uso del quechua escrito por indígenas. Esperamos también contribuir al estudio de los discursos legales andinos durante el período colonial. En los últimos años este tema ha sido objeto de estudios importantes, aunque en la mayoría de los casos los autores se enfocan en documentación en castellano debido a la rareza de escritos legales en quechua
Seguridad hídrica y la panacea de las licencias de agua en el Valle del Colca, Perú
Authors: Seemann Miriam
Published: March 2023

El presente capítulo sostiene que, en lugar de reforzar la seguridad hídrica de la población local, la formalización de los derechos de agua a nivel local afianza, principalmente, las inseguridades hídricas, manifestadas en la tendencia de que el más vulnerable se vuelve más vulnerable aún. Para desarrollar este argumento, primero se describe el área de estudio, segundo, se presenta el PROFODUA y se hace un escrutinio sobre las posibilidades de cumplir los requerimientos (tarifas de agua y títulos de propiedad) para obtener licencias hídricas; y, por último, se analizan las contradicciones entre la seguridad hídrica local y las licencias de agua.

En este trabajo me voy a concentrar en los tipos de harawi cuyo contenido fue reconocido como histórico por los españoles. Estos cantares se entonaban en ceremonias en las que participaban los gobernantes fallecidos que habían sido embalsamados. Sus cuerpos estaban colocados en cuclillas sobre soportes de paja o barro y envueltos en finísimas telas. También se sabe que estos cuerpos tenían un álter ego o wawqi, que podía ser una piedra u otro objeto, y que los representaba. Para los indígenas, estos cuerpos eran sagrados; para los españoles, «bultos».
Dynamics and Structure of International Labor Migration: Global Trends
Authors: Rubinskaya Eteri
Published: March 2023

The article is devoted to the analysis of the process of international labor migration, the definition of factors affecting its scale, geographical directions and quality component. It was revealed that negative demographic trends in developed countries (birth rate decline, aging of the population) generate disproportions in their national labor markets, turning migration into the most important and, actually, the only source of labor force replenishment. In Western Europe, workers of foreign origin make up 18.4% of the total workforce, in Australia, Canada, and the United States it is about 20%. The effective functioning of some sectors of the economy in developed countries is already dependent on the labor of migrants. The trend to increase the share of foreign labor in the labor markets of these countries will grow. On the other hand, under the influence of scientific and technological progress, the needs of the labor market are being transformed, the demand for highly skilled and skilled labor is increasing. Through preferential migration regimes, countries are trying to attract foreign specialists, including potential (foreign students), thereby increasing the role of educational migration in the migration flow, its scale is growing, the flows of highly qualified specialists are intensifying, contributing to a change in the qualitative component of labor migration.
Cross-cultural marriages as a reserve of demographic development in Russia
Authors: Rostovskaya Tamara , Kuchmaeva Oksana
Published: March 2023

With the deepening of the process of globalization, the scale of interaction between different cultures, their interpenetration, mixing is expanding, which increases the possibility of cross-cultural marriages. The problems of the analysis of cross-cultural marriages in Russia and Iran seem to be an urgent direction for research. Cross-cultural marriages between Russians and Iranians serve as one of the significant elements of the process of rapprochement of two different cultures, and also contribute to the development of interest and tolerant attitude of Russians to the cultural traditions of the East. The purpose of this work is to analyze the attitude of Iranians and Russians to cross-cultural marriages against the background of the transformation of the desired family model, to identify the factors of the formation of cross-cultural marriages. The conclusions are based on the results of the International sociological study "Russian-Iranian marriages in the context of intercultural interactions", conducted in June-September 2021 in the cities of Russia and Iran by a team of authors. The sample size was 153 people, including representatives of different generations aged 18 to 60 years. The results of the survey revealed ideas about the model of family and marriage for residents of Iran and Russia. The study identified the main motives for concluding a cross-cultural marriage, the respondents' views on family relationships, as well as their attitude to the official registration of the status of spouses. A separate block of questions was aimed at studying the problems and living conditions of spouses in cross-cultural marriages, the need for special support measures. The attitude to cross-cultural marriages in society, both on the part of Russians and Iranians, is considered. The results obtained can be used in the development of strategies for the development of socio-cultural interaction between Russia and Iran. It is important to take into account the conclusions of the study as part of efforts aimed at smoothing out possible acute issues of interethnic relations; providing support to cross-cultural families in the process of adaptation and familiarization with the norms, traditions, customs of a new culture for the spouse.

The article shows the changes taking place with socio-cultural, ideological processes and mass consciousness under the conditions of not quite favorable socio-political situation. In this regard, the issues of further socio-cultural development of the country, forms and methods of social transformation become relevant for the study. The dynamics of the socio-cultural processes taking place in the country show that Russia cannot confess Western values and follow the Western vector of development, despite the pressure from outside. The article is based on the results of a study conducted by the Center for the sociology of ideological and socio-cultural processes, ISPR FCTAS RAS, conducted in 2022, which was influenced by both the beginning of the post-pandemic period and the beginning of a special military operation. The study was conducted in Moscow, the Murmansk and Arkhangelsk oblasts, and the Nenets Autonomous Okrug. Social democratic values: human rights and freedoms, safety, social security, as well as the level of trust in religious institutions, were subjected to a special study. The author concludes that the dynamics of socio-cultural processes cannot move forward without improving the geopolitical situation with its restrictive measures and other obstacles.
Properties of the average time benefit for probabilistic models of exploited populations
Authors: Woldeab Mebrahtom S.
Published: March 2023

A model of a homogeneous population given in the absence of exploitation by a differential equation x ̇=g(x) is considered. At each moment of time τ_k=kd, where d>0, k=1,2,..., some random share of the resource ω_k ∈ [0,1] is extracted from this population. We assume that it is possible to stop the harvesting if its share turns out to be greater than a certain value u∈[0,1): then the share of the extracted resource will be l_k=l(ω_k,u)=min(ω_k,u), k=1,2,.... The average time benefit from resource extraction is investigated, it is equal to the lower limit of the arithmetic amount of the resource obtained in n extractions as n→∞. It is shown that the properties of this characteristic are associated with the presence of a positive fixed point of the difference equation X_(k+1) = φ(d,(1-u)X_k), k=1,2,..., where φ(t,x) is a solution of the equation x ̇=g(x) satisfying the initial condition φ(0,x)=x. The conditions for the existence of the limit and the estimates of the average time benefit performed with probability one are obtained. The results of the work are illustrated by examples of exploited homogeneous populations depending on random parameters.

Corrupción y lucha contra la corrupción desde una perspectiva regulatoria
Authors: De Benedetto Maria
Published: March 2023

El objetivo del presente trabajo es reconsiderar la lucha contra la corrupción desde una perspectiva regulatoria. De hecho, aunque la regulación solía considerarse la primera y más poderosa herramienta para combatir y prevenir la corrupción, paradójicamente, las leyes y los reglamentos ofrecen oportunidades para la búsqueda de rentas y pueden utilizarse como herramientas para obtener beneficios. Cuando una normativa establece actividades y controles administrativos, por ejemplo, hace a los agentes públicos más vulnerables al soborno u otros intercambios ilícitos. Este enfoque requiere una estrategia reguladora anticorrupción integrada –enriquecida por las aportaciones de las ciencias del comportamiento– que combine diferentes herramientas. Dicha estrategia implicaría una mejoría de la regulación, como la simplificación y la evaluación ex ante y ex post de la legislación y la regulación; la transparencia sobre los intereses afectados por la legislación e implicados en el proceso de elaboración de la ley; la evaluación de la regulación para detectar posibles casos de corrupción; la gestión anticorrupción de la normativa existente.

Published: March 2023

Purpose: This study aimed to investigate the effect of using a keratin solution as a pretreatment agent on damaged hair.Methods: The solution was applied differently with 50% and 100% keratin. Hair tensile strength, absorbance using methylene blue, and gloss were measured, and analysis was performed after scanning electron microscope photographing to determine the effect on damaged hair.Results: Tensile strength, absorbance, and gloss measurement results showed that the average values increased, decreased, and increased for all samples applied rather than for damaged hair, respectively; the statistical results showed a significant difference. By analyzing the cuticle image, the condition was found to be better than that of the control group.Conclusion: The tensile strength, absorbance, gloss, and hair skin analysis of the specimens applied with keratin solution showed differences, which affected the damaged hair.
Design Form of Graduation and Incremental Layer Cut according to Segmentation of Head Regions, Slice Line and Angle
Authors: GuK Hye Ran
Published: March 2023

Purpose: This research investigated how changing the division of a head area affects design. Furthermore, this research aimed to understand the variations in design form based on the slice line, present a sample of the cut design, and provide basic data for haircuts.Methods: The upper head was divided in to three areas by from the center point to the golden back medium point-then ear back point, from the center point to the back point-then ear back point, and from the center point to the back nape medium point- then ear back point. The upper head angle was 45° and the slice line adopts A line, parallel line, and V line. The upper and lower head angles were 110°, 130°, and 150°.Results: A line and V line became more distinct toward the face line, while the parallel line appeared flatter. There was no weight line in the incremental layer cut, and there was no noticeable difference in the change according to the angle in the concave stretched shape. When dividing the head area, the length was shortened when the starting point of the upper part was placed upward and lengthened when it was placed downward. The medium gradient cut appeared on the edge of the weight without falling hair on the same line.Conclusion: A line exhibited increased volume, weight, and expansion, while V line showed a decrease in these factors but an increase in volume, rhythm, and vitality. A line was observed to be mature and thin, while V line was cute and sporty, and the parallel line was plain and neat. Even with the same slice line, the length varied based on the segmentation of the head region. The head division, slice line, and angle should be selected based on the customer's head shape, face shape, and taste.

Aims: Blood biomarkers can improve drug development for Alzheimer’s disease (AD) and its treatment. Neuron-derived extracellular vesicles (NDEVs) in plasma offer a minimally invasive platform for developing novel biomarkers that may be used to monitor the diverse pathogenic processes involved in AD. However, NDEVs comprise only a minor fraction of circulating extracellular vesicles (EVs). Most published studies have leveraged the L1 cell adhesion molecule (L1CAM) for NDEV immunocapture. We aimed to develop and optimize an alternative, highly specific immunoaffinity method to enrich blood NDEVs for biomarker development. Methods: After screening multiple neuronal antigens, we achieved NDEV capture with high affinity and specificity using antibodies against Growth-Associated Protein (GAP) 43 and Neuroligin 3 (NLGN3). The EV identity of the captured material was confirmed by electron microscopy, western blotting, and proteomics. The specificity for neuronal origin was demonstrated by showing enrichment for neuronal markers (proteins, mRNA) and recovery of spiked neuronal EVs. We performed NDEV isolation retrospectively from plasma samples from two cohorts of early AD patients (N = 19 and N = 40) and controls (N = 20 and N = 19) and measured p181-Tau, amyloid-beta (Aβ) 42, brain-derived neurotrophic factor (BDNF), precursor brain-derived neurotrophic factor (proBDNF), glutamate receptor 2 (GluR2), postsynaptic density protein (PSD) 95, GAP43, and syntaxin-1. Results: p181-Tau, Aβ42, and NRGN were elevated in AD samples, whereas proBDNF, GluR2, PSD95, GAP43, and Syntaxin-1 were reduced. Differences for p181-Tau, proBDNF, and GluR2 survived multiple-comparison correction and were correlated with cognitive scores. A model incorporating biomarkers correctly classified 94.7% of AD participants and 61.5% of control participants. The observed differences in NDEVs-associated biomarkers are consistent with previous findings. Conclusion: NDEV isolation by GAP43 and NLGN3 immunocapture offers a robust novel platform for biomarker development in AD, suitable for large-scale validation.
