ACESSO À JUSTIÇA E O CONTROLE JUDICIAL NA CONCESSÃO RESPONSÁVEL DA ASSISTÊNCIA JUDICIÁRIA GRATUITA
Authors: Martins Daniel , Meyer Rosane Stedile Pombo , Iocohama Celso Hiroshi
Published: September 2023

O trabalho apresenta uma análise acerca da gratuidade judicial como instrumento do direito de acesso à justiça e a crise existente em razão do uso abusivo do benefício ladeado a preocupações de cunho econômico, estrutural e de elevação do número de processos judiciais. Passa-se a evocar a vigência do Estado Democrático e Social de Direito, debatendo-se questões no sentido de limitação da gratuidade judicial pelos problemas havidos. O estudo finaliza apontando a necessidade de se combater os abusos na utilização da gratuidade, que deve ser realizado por todos os operadores do direito, sobretudo no controle judicial efetivo  para que se dê a (não) concessão de forma responsável, inclusive com a adoção de critérios mais objetivos, contudo, sem se descuidar da importância do mecanismo para o acesso à justiça, da imperativa aplicação do princípio da proibição do retrocesso e a preservação do núcleo essencial do direito fundamental.

Authors: Jena Sweekruti , Mishra Ipsita , Baliarsinha Anoj Kumar , Jena Debarchan
Published: September 2023

Complete androgen insensitivity syndrome (CAIS) is a rare disorder that is often diagnosed in the pubertal period during the evaluation of primary amenorrhea. Diagnosis is important not only in the context of early removal of undescended testis but also in terms of the grave psychological outcome of the diagnosis on the adolescent and family members. Here, we present case reports of two sisters who presented with primary amenorrhea. It is imperative to keep CAIS as a differential during the evaluation of primary amenorrhea. CAIS may also present as a case of a childhood inguinal hernia.
Unique presentation of Mauriac syndrome with associated celiac disease in an adolescent with type 1 diabetes mellitus: A case report
Authors: Priyadarshini Prerna , Jaiswal Vijay , Agarwal Vikas , Kumari Surabhi
Published: September 2023

We report an adolescent girl with Mauriac syndrome diagnosed in merely 3 years of diagnosis of type 1 diabetes mellitus with poor glycemic control and associated celiac disease. A 11-year-old girl with poor metabolic control characterized by recurrent hypoglycemia and hyperglycemia presented with Mauriac syndrome comprising stunting, hepatosplenomegaly, and elevated serum transaminases without cushingoid features, within 3 years of diagnosis of type 1 diabetes mellitus. Serum tissue transglutaminase antibodies were elevated. The girl also had coexisting celiac disease. She improved with adequate glycemic control along with a gluten-free diet, iron, and other supplements with regression in the size of the liver and reduction of liver enzymes. Mauriac syndrome should be considered in type 1 diabetic patients with poor metabolic control and hepatomegaly irrespective of the duration of diabetes mellitus. Recurrent hypoglycemia and the presence of Mauriac syndrome are signs of associated autoimmune disorders.

Objectives:

In October 2020, the Ministry of Health and Child-care Zimbabwe commenced integrating reproductive health with human immunodeficiency virus (HIV) services. Family planning (FP), sexually transmitted infection (STI) screening and treatment, HIV testing services (HTS), pre-exposure prophylaxis (PrEP), and antiretroviral therapy (ART) services were offered through an integrated one-stop-shop model. The project aimed to address unacceptably high incidences of HIV and STIs among FP clients and demonstrate improved access and uptake of integrated services at dedicated FP centers.

Materials and Methods:

We conducted an intervention study. A service package of STI symptom screening and HTS (including HIV self-test [HIVST] primary and secondary distribution) was offered to all FP clients by multi-skilled nurses. Service uptake was measured pre and post-introduction of the intervention, before which services were provided by different nurses, in different rooms. HIV-diagnosed clients were linked to ART and eligible negative testers were offered PrEP. Service uptake was measured at 1 year of implementation against the same period before.

Results:

A total of 20,947 clients were recruited between October 2019 and September 2021, 9386 pre-intervention and 11,561 post-intervention. We observed a 5.2% total increase in clients seen and a 27.1% increase in the average uptake of all integrated services (FP, STI, HTS, PrEP, and ART). Most (93.5%) clients received oral contraception (Progestogen-only pills and combined-oral-contraceptives), while fewer (4.8%) received injectables and implants (1.1%). Following the intervention, STI screening increased by 30.2% (2730 vs. 11,028). HTS delivery increased by 38.9% and PrEP by 44.1%. HIV positivity yield increased significantly (10.1%, 62/615 vs. 16.6%, 813/4910) and linkage to ART improved by 44.4%. HIVST distribution contributed to improved access to HIV testing with 3754 FP clients accepting distribution compared with 4910 receiving HTS by nurses, provider-delivered testing was accessed by reactive self-testers. The project increased (?) improved linkage to preventive and treatment services and reduced missed opportunities associated with fragmented services.

Conclusion:

The integrated one-stop-shop model demonstrated improved service uptake during the intervention period. This project shows the benefits of integrated FP/STI/HTS/PrEP in Zimbabwe’s high HIV burden settings.

Purpose. Demonstration of a clinical case of the formation of carotid-cavernous fistula (CCF), which we observed in our ophthalmological practice. Material and methods. A 52-year-old patient who was urgently referred for surgical treatment of orbital phlegmon, accompanied by a decrease in vision to 0.02, reactive eyelid edema, secondary glaucoma, and rather mild exophthalmos of the left eye. On the same day, she was admitted to the hospital, where she underwent an opening and drainage of the orbit. However, after 5 days, against the background of further anti-inflammatory therapy, the patient began to be disturbed by a noise in the head, reminiscent of the «noise of a steam locomotive», and pain in the left eye appeared. Conducted selective computed tomography with angiography made it possible to establish the final diagnosis: cerebrovascular disease, arteriovenous malformation in the projection of the supraclinoid section of the left internal carotid artery, post-traumatic CCF on the left side. First, the patient underwent a course of vascular, decongestant, and symptomatic therapy, and then endovascular embolization CCF of the left side was successfully performed. Results. After that, headaches and noise in the head disappeared, exophthalmos and congestion in the form of edema of the eyelids and bulbar conjunctiva gradually regressed. However, the visual acuity of the left eye remained reduced (0.03) due to atrophy of the optic nerve. Conclusion. The rare occurrence of this pathology in ophthalmic practice may cause the lack of alertness of doctors of this specialty in terms of timely diagnosis of CCF. At the same time, it should be taken into account that neuroophthalmic symptoms are of decisive importance in clarifying the indications for the accelerated conduct of the only effective surgical endovascular treatment of this pathology. Particular care should be taken in cases where the patient has unilateral exophthalmos with a pulsating noise in the head and a history of blunt head trauma from several days to 2 months before their onset.

Purpose. To study retinal blood flow in pregnant women with disorders of carbohydrate metabolism using optical coherence tomography angiography (OCTA) in order to determine the criteria for the manifestation and progression of diabetic retinopathy (DR). Material and methods. 203 pregnant women in the third trimester were examined: 24 – with type 1 and 2 diabetes (T1D and T2D), 143 – with gestational diabetes (GD), and 36 apparently healthy women with physiological pregnancy, who consisted the control group. OCTA imaging was performed using the RTVue XR Avanti OCT 6 mm × 6 mm «Angio Retina» scan protocols (Optovue, USA). The whole image vessel density (wiVD), foveal vessel density (FVD), and foveal avascular zone (FAZ) area in the superficial capillary plexus were studied. Results. FVD in pregnant women with diabetes was significantly less than in pregnant women with GD and in the control group. In this connection, it can be assume changes of the retinal microvascular regulation, due to chronic disorders of carbohydrate metabolism in patients with diabetes, and development of microangiopathy. Enlargement of FAZ area and decrease of wiVD were revealed in patients with DR, relative to datas obtained in the group of pregnant women with diabetes and absence of DR, in the absence of differences in FVD indexes. In 2 patients with T1D and the absence of ophthalmoscopic signs of DR, OCTA revealed areas of nonperfusion in the posterior pole of the eye. Conclusion. OCTA helps to identify areas of retinal nonperfusion in the posterior pole of the eye in pregnant women with diabetes in the absence of ophthalmoscopic signs of DR and allows determining objective indications for timely retinal laser coagulation.

Published: September 2023

Generative artificial intelligence (GenAI) has the potential to drastically alter how we teach and conduct research in chemistry education. There have been many reports on the potential uses, limitations, and considerations for GenAI tools in teaching and learning, but there have been fewer discussions of how such tools could be leveraged in educational research, including in chemistry education research. GenAI tools can be used to facilitate and support researchers in every stage of traditional educational research projects (e.g. conducting literature reviews, designing research questions and methods, communicating results). However, these tools also have existing limitations that researchers must be aware of prior to and during use. In this research commentary, we share insights on how chemistry education researchers can use GenAI tools in their work ethically. We also share how GenAI tools can be leveraged to improve accessibility and equity in research.

Published: September 2023

Natural products exhibit interesting structural features and significant biological activities. The discovery of new bioactive molecules is a complex process that requires high-quality metabolite profiling data to properly target the isolation of compounds of interest and enable their complete structural characterization. The same metabolite profiling data can also be used to understand chemotaxonomic links between species better. This Data Descriptor details a dataset resulting from the untargeted liquid chromatography-mass spectrometry profiling of 76 natural extracts of the Celastraceae family. The spectral annotation results and related chemical and taxonomic metadata are shared, along with proposed examples of data reuse. This data can be further studied by researchers exploring the chemical diversity of natural products. This can serve as a reference sample set for deep metabolome investigation of this chemically rich plant family.

Published: September 2023

The relationship between the fluorescence decrease by Aggregation-Caused Quenching (ACQ) and the Photoacoustic Generation Efficiency in polylactide-Bodipy nanoparticles (PLA-Bodipy NPs) is demonstrated. PLA NPs with different PLA-Bodipy loading (from 2.5% to 50% by weight) were studied using a calibrated photoacoustic spectrophotometer. We demonstrate the presence of two photoacoustic emission regimes thanks to the determination of the Global PhotoAcoustic Efficiency (GPAE) which represents the averaged Photoacoustic Generation Efficiency (PGE) over the whole studied band (680-870 nm). In the monomer regime, below 10% by weight of PLA-Bodipy, the fluorescence emission from the Bodipy monomer limits the GPAE. Above 10% of PLA-Bodipy, in the ACQ regime, non-radiative deactivations from the aggregates are predominant and GPAE reaches a high value of 93%. We also introduce the photoacoustic brightness BPA, as the produce of the GPAE by the molar extinction coefficient of NPs. When Bodipy is aggregated, high nanoparticular extinction coefficients (2.4 x 108 L.mol-1.cm-1 for NP-50%) and high GPAE values are reached leading to ultrabright NPs (22 x 107 L.mol-1.cm-1). Finally, we show that high laser fluences (1-3.5 mJ.cm-2) can significantly reduce the photoacoustic signal by ground state depopulation at the band maximum excitation (-20% for NP-2.5%). This non-linear effect can be highly reduced with NPs in the ACQ regime. Above 10% PLA-Bodipy, NPs exhibit intense photoacoustic brightness and low signal loss by nonlinear effects. A mathematical fit of the absorption and photoacoustic excitation spectra allowed to introduce the Band PhotoAcoustic Efficiency (BPAE) to spectrally differentiate the averaged photoacoustic efficiency at the band maximum BPAEred and in the vibrational shoulder BPAEblue. The BPAEred highly depends on the laser fluence due to high ground state depopulation, whereas the BPAEblue does not change with the fluence thanks to a lower laser fluence saturation.
Ligand-Enforced Geometries and Associated Reactivity in P-Block Compounds
Authors: Hannah Tyler , Chitnis Saurabh
Published: September 2023

The geometry at an element centre can generally be predicted based on the number of electron pairs around it using valence shell electron pair repulsion (VSEPR) theory. Strategies to distort p-block compounds away from these predicted geometries have gained considerable interest due to the unique structural outcomes, spectroscopic properties or reactivity patterns engendered by such distortion. This review presents an up-to-date group-wise summary of this exciting and rapidly growing field with a focus on understanding how the ligand employed unlocks structural features, which in turn influences the associated reactivity. Relevant geometrically constrained compounds from groups 13-16 are discussed, along with selected stoichiometric and catalytic reactions. Several areas for advancement in this field are also discussed. Collectively, this review advances the notion of geometric tuning as an important lever, alongside electronic and steric tuning, in controlling bonding and reactivity at p-block centres.
Mirar Madrid: Areta y el paisaje urbano en la trilogía El crack de José Luis Garci
Authors: Martínez Illán Antonio , Muñoz-Garnica Miguel
Published: September 2023

El crack (1981), El crack dos (1983) y El crack cero (2019) de José Luis Garci conforman una trilogía que adapta el género del cine negro estadounidense a la realidad del Madrid de la Transición, abarcando desde los meses previos a la muerte de Francisco Franco hasta 1982. Este artículo analiza la que consideramos principal clave expresiva de los tres títulos: la continuidad y complementariedad expresiva entre Germán Areta, el detective protagonista, y la imagen de Madrid. Detectamos dos patrones estéticos sostenidos a lo largo de la trilogía: los planos de paisajes urbanos presentados en continuidad interna con la mirada de Areta, y las sucesiones no narrativas de planos de la ciudad en los que no media la presencia del protagonista. Ambos recursos nos permiten desplegar un análisis textual de las películas para ilustrar cómo se construye esa continuidad ciudad-personaje, propia del cine negro clásico pero mucho más radical en manos de Garci.
La publicidad en la financiación de la prensa en papel: costes y escenarios comerciales
Authors: Ortega Fernández Eglée , Martín García Noemí , Arranz Rodríguez Inés
Published: September 2023

La prensa en papel se ha visto afectada por la aparición de los medios digitales, por la bajada de audiencia, de venta de ejemplares y de ingresos publicitarios. Estos cambios han impactado en su modelo de negocio y perspectivas de futuro, dando si cabe un mayor poder a los ingresos procedentes de la venta de los espacios publicitarios. El objetivo principal de esta investigación es profundizar sobre los cambios que se han producido en los precios de los anuncios publicitarios de la prensa impresa en la última década (2013-2022) y analizar los futuros escenarios comerciales a los que se enfrenta el medio en los próximos años. Para ello, se ha empleado una metodología mixta. La parte cuantitativa se centra en el análisis de los precios de compra de los anuncios, mientras que la parte cualitativa se focaliza en las opiniones de los profesionales del sector que trabajan diariamente en la selección de los emplazamientos publicitarios para las marcas. Los resultados ponen de manifiesto un precio cada vez menor por el espacio publicitario en la prensa impresa, sobre todo en los diarios nacionales, a pesar de un aumento de las tarifas oficiales que los soportes. Asimismo, muestran un escenario comercial centrado en la especialización, la credibilidad y la seriedad del medio frente a la venta masiva de publicidad. Las conclusiones ponen de manifiesto las dificultades de la supervivencia del medio impreso con el sistema de financiación actual, pero les abre una vía para la realización de estrategias comerciales que refuercen las características que lo diferencian del online.
Análisis de impacto del uso del clickbait en los perfiles de Twitter de los medios de comunicación españoles
Authors: Flores-Vivar Jesús Miguel , Zazo-Correa Laura
Published: September 2023

El artículo aborda el uso del clickbait en el ecosistema mediático actual, dominado por la hegemonía de las redes sociales y en el que la competencia por atraer la atención de los usuarios es cada vez mayor entre los medios de comunicación. En este escenario, uno de los retos a los que se enfrenta el periodismo es la desinformación, pero, también, al desafío de atraer lectores a sus sitios web, por lo que cada vez es más habitual el uso de titulares que buscan llamar la atención del usuario para que haga clic en el enlace, sin importar el rigor informativo de los mismos, lo que puede provocar una mayor desinformación. En razón a ello, este trabajo busca analizar los contenidos (mensajes) que se dan en los perfiles de Twitter de los principales medios de comunicación españoles, que utilizan técnicas como el clickbait y, evaluar si los titulares cebo producen más desinformación o no, en el panorama mediático español. La metodología se basa en el análisis de contenido de los perfiles en Twitter de los medios de comunicación españoles tales como ABC, El País, El Mundo, Público, Diario.es, RTVE Noticias, COPE, Cadena Ser, Onda Cero, Antena 3 Noticias, Noticias Cuatro y La Sexta Noticias. Los resultados señalan que los medios analizados hacen un uso muy bajo de esta práctica y se concentra, principalmente, en secciones como Sociedad o Ciencia. Cabe destacar que, a pesar de hacer un bajo uso del clickbait, se observa el uso de otras fórmulas, como las preguntas en los titulares, buscando atraer usuarios y aumentar el número de páginas vistas.
Las fuentes en el sistema híbrido de medios: la cobertura de la desigualdad en la pandemia
Authors: Odriozola Chéné Javier , Pérez Arozamena Rosa
Published: September 2023

La llegada de internet ha supuesto un cambio en el ecosistema mediático. Las empresas periodísticas, denominadas legacy media, han perdido el monopolio en los procesos de comunicación de masas teniendo que convivir con nuevos actores mediáticos. En este contexto, las viejas y las nuevas lógicas de producción conviven e interactúan de tal manera que los medios tradicionales y los nuevos se adaptan y evolucionan. El objetivo de esta investigación es mostrar el efecto de estos cambios en los contenidos periodísticos en relación al uso de fuentes de información y la identidad de las mismas. Para ello, se realiza un análisis de contenido sobre una muestra de 958 relatos periodísticos producidos por seis cibermedios españoles durante el primer año de la pandemia. Tales textos abordan el incremento de la desigualdad como consecuencia de la crisis derivada de la COVID-19. Los resultados muestran que dinámicas vinculadas al nuevo ecosistema mediático pueden limitar el uso de fuentes de información reduciendo la calidad periodística. Pero, por otro lado, también constatan cómo la mayor importancia concedida a actores sociales, que tradicionalmente no han centrado el interés mediático, contribuyen a la mejora de los productos periodísticos.
Pantalla aumentada, triple narrativa y el rol del usuario: un estudio de caso
Authors: Sosa-Fernández Rocío del Pilar , Calvete-Lorenzo Sara , Rozados-Lorenzo Andrés
Published: September 2023

El presente panorama muestra una sociedad saturada de imágenes, impulsada por la utilización de dispositivos móviles y un consumo audiovisual constante. No obstante, no se logran mayores aptitudes en las personas usuarias, sino que, por el contrario, se evidencia un detrimento en el índice de atención y la búsqueda de un producto diferenciador del amplio rango de contenido disponible. Dado esta reciente incertidumbre, la industria cinematográfica ha encontrado en la tecnología una gran aliada. La existencia de tecnologías como la realidad aumentada aún se encuentra en un proceso incipiente y genera nuevas interrogantes sobre el potencial de su empleo en el cine. En el presente estudio se llevó a cabo un análisis de caso del primer cortometraje con realidad aumentada de Disney, Remembering (Allan-Blitz, 2022). La metodología utilizada se centra en tres enfoques: el lenguaje audiovisual, el visionado con la tecnología y el papel del receptor. Los resultados evidencian la existencia de una disparidad digital y económica, debido a la particularidad de los dispositivos de visualización. Además, el relato presenta una narrativa tripartita; una más pausada y simple con planos amplios, otra más rápida e inestable en el que confluyen espacios físicos y virtuales y una última creada por la persona usuaria como steadycam. Estas lecturas requieren un espectador más activo y presente, en un relato carente de la adaptación del lenguaje audiovisual a la nueva forma de visualización, en el cual no se aprovechan las posibilidades de tiempo y espacio que ofrecen estas tecnologías.
Cuando el espejo retrovisor te lleva al futuro. Una revisión histórica sobre McLuhan y la Ecología de los Medios
Authors: Islas-Carmona Octavio , Arribas Urrutia Amaia
Published: September 2023

El artículo tiene el objetivo de realizar una revisión histórica, con propósitos hermenéuticos, con la finalidad de referir dos relevantes contribuciones al desarrollo de una ciencia y al desarrollo de una metadisciplina, cuya relevancia y significado fueron advertidas de manera tardía. La primera de la cual nos ocuparemos se ubica en el plano de la comunicología; la segunda, en el imaginario de la ecología de los medios. En la primera, destacamos que Marshall McLuhan (1911-1980), principal referente seminal en la ecología de los medios, al rechazar el determinismo sociologizante contribuyó a instalar al estudio de los medios de comunicación y a la comunicología en el imaginario científico. En la segunda parte referirmos que la ecología de los medios, -la compleja metadisciplina que derivó de búsqueda intectual de McLuhan y Neil Postman- que se ocupa de analizar el impacto de las tecnologías en los ambientes culturales en las sociedades a través de la historia, extendió significativamente su aparato reflexivo al redescubrir la semántica general, cuyos fundamententos epistemológicos fueron establecidos por Alfred Korzybski en 1934.

The article presents a numerical simulation of nonstationary heat conduction problems under complex heat transfer, which includes such heat transfer mechanisms as heat conduction, convection, and radiation. The Stefan-Boltzmann law describes the resulting heat transfer by radiation between two bodies, where the heat transfer coefficient is a function of the body surface temperature. An algorithm and software for solving the heat conduction problem using the finite element method were developed, and the influence of external impacts on the temperature field distribution in the vicinity of an insulated circular hole in the center of the body was studied. The temperature fields were investigated for various boundary conditions in the hole of the plate and the corresponding isotherms were given.
Algebras of Binary Isolating Formulas for Strong Product Theories
Authors:   Novosibirsk State Technical University, Emel’yanov D. Yu.
Published: September 2023

Algebras of distributions of binary isolating and semi-isolating formulas are objects that are derived for a given theory, and they specify the relations between binary formulas of the theory. These algebras are useful for classifying theories and determining which algebras correspond to which theories. In the paper, we discuss algebras of binary formulas for strong products and provide Cayley tables for these algebras. On the basis of constructed tables we formulate a theorem describing all algebras of distributions of binary formulas for the theories of strong multiplications of regular polygons on an edge. In addition, we shows that these algebras can be absorbed by simplex algebras, which simplify the study of that theory and connect it with other algebraic structures. This concept is a useful tool for understanding the relationships between binary formulas of a theory.

The stochastic analogue of the Riemann matrix in block form is introduced, an integral representation of the solution of the boundary value problem under consideration is obtained in an explicit integral form in terms of boundary conditions.
Resolution of Linear-quadratic Problems in a Discrete-continuous Format with External Actions
Authors:   Irkutsk State University, Srochko V. A. , Antonik V. G. ,   Irkutsk State University
Published: September 2023

Two linear-quadratic problems are considered on the set of piecewise-constant controls. The first problem contains a discrete perturbation on the right side of the controlled system and uncertain parameters in a quadratic functional with sign-indefinite matrices. Its solution is obtained by the guaranteed result rule and is implemented in the form of a finite-dimensional minimax problem. There are obtained conditions for the parameters that convert the objective function to a convex-concave structure and give the possibility of an effective solving of the problem. These are linear inequalities containing extreme eigenvalues of symmetric matrices. The second problem is related to the functional in the discrete variant, which is defined as the deviation of the phase trajectory from consecutive time realizations of the external influence. It gives the opportunity of the step by step searching of the extremmum at each node point of the time interval. Local problems can be effectively solved in a finite number of iterations.

A variational problem for the minimum of the stored energy functional is considered in the framework of the nonlinear theory of elasticity, taking into account admissible deformations. An algorithm for solving this problem is proposed, based on the use of a polygonal partition of the computational domain by the Delaunay triangulation method. Conditions for the convergence of the method to a local minimum in the class of piecewise affine mappings are found.

The potential use of large red galangal (Alpinia purpurata, K. Schum) essential oil has a
weakness that is prone to compound damage. Thus, it is necessary to make efforts to
maintain the active compounds contained in the red galangal rhizome essential oil, one of
which is by microencapsulation. The purpose of this study was to determine the
appropriate formulation of the material coating used in the microencapsulation process
using the freeze-drying method. The optimization of the microencapsulation process was
carried out using the response surface method (RSM) with the central composite design
(CCD). The optimization results of essential oil microcapsules showed that the yield
response of 44.01%, water content of 5.75%, TPC of 34.227 mg GAE/g, antioxidant
activity (IC50) of 136.01 ppm, and solubility of 87.70%. The GC-MS analysis has shown
that there were five main compounds detected from the microcapsules, Diacetone alcohol
of 31.36%, Chavicol of 15.26%, Methyl oleate of 6.87%, Alloaromadendrene of 5.82%
and Methylhexadecanoate of 3. 44%. Overall, the choice of coating material can affect the
characteristics and morphology of the microcapsules.
Biochemical components and sensory acceptance of a ready-to-drink from sea
buckthorn berries
Authors: Kumari S. , Sharma P.S.
Published: September 2023

Sea buckthorn (Hippophae rhamnoides), also known as Chharma as well as a member of
the Elaeagnaceae family, naturally occurs in Himachal Pradesh's high-altitude highlands
amid harsh weather circumstances. This current research detailed the processing of sea
buckthorn fruit juice into a ready-to-drink (RTD) drink, as well as variations throughout
the beverage's condition improves after preservation about three months. During the
September quarter, when the fruits were fully mature, sea buckthorn berries were picked
from the Lahaul valley. The pulp was removed from the berries using a fruit pulper.
Variable quantities of pulp and sugar were used in the beverage compositions to create
ready-to-drink beverages. The ascorbic acid level rose considerably with increasing pulp
percentage and declined with increasing curing time. In contrast, a growing tendency in
decreasing sugars were found with increasing pulp and sugar concentration as well as
storage time. A beverage composition combining 10%, 12% and 15% pulp with total
soluble solids (TSS) 11°, 15° and 15°Bx respectively of zero-day prepared drink were
voted the most acceptable by a panel of judges on a nine-point hedonic scale. It was
determined that adding value to sea buckthorn can help to establish a commercial sector
for such a natural berry, that has been ignored and underused in Himachal Pradesh.
Transformation of Institutions in the Modern Economy

The subject of the study is institutional changes in the economy, their causes and consequences. The purpose of the work is to show that purposeful changes in the rules on which the international order is based have become an effective method of economic policy both at the national level and within the framework of the world system and international relations, causing systemic dysfunctions that are formed along institutional and managerial contours and are determined by the use of new technologies. The research methodology is based on institutional and comparative analyses, as well as on the theory of dysfunctions to highlight the independent significance of institutional and technological changes. The influence of the dysfunction of institutions and management on the efficiency of the functioning of the economy and the formation of conditions for subsequent institutional transformations is shown. The model of institutional competition is considered and it is proved that, along with competition in products, services, resources and technologies, it is of greater importance in the modern economy, since competition in objects is determined by the institutional conditions of business organization and markets. It is established that economic agents participate in institutional competition by building schemes for lobbying their interests, and institutional competition itself is carried out at the level of public administration — the legislative and executive branches of government. It is revealed that the transformation of international institutions is currently taking place frontally under the influence of sanctions wars. It is concluded that the dysfunction of institutions and management (control) is the cause of the "administrative trap of rules", which is shown by the example of healthcare management in Russia, when patients are sent to medical institutions to receive high-tech specialized medical care. The result of the study confirms the author's argument about the need to build their own internal rules in Russia and overcome external dependence on institutions that generate a regime of institutional competition on the rights of a slave, not a leading participant, as well as reducing the dysfunction of control.
Express Diagnostics of the Region's Population

The subject of the study is a complex of social relations arising in the process of providing social support measures to the population of the region through the use of new information and communication technologies. The purpose of the work is to identify methodological tools that contribute to improving the effectiveness of providing social support to the population. As a result of the study, it was revealed that the decreasing number of labor resources of the Chelyabinsk region can be replenished by immigrants from other regions and migrants, which requires a comprehensive assessment of the impact of demographic and economic factors on the employment level of the population of the Chelyabinsk region. Based on the diagnosis of labor resources and the level of employment of the population of the Chelyabinsk region, proposals are put forward to increase the number of working-age labor resources and assess the effectiveness of these proposals. It is emphasized that the labor resources include the able-bodied population of working age. Consequently, for the growth of labor resources, the level of employment should increase due to the economically inactive population or the growth of migration. By analyzing the dynamics of employment of the population of the Chelyabinsk region in 2020-2021. a regression model is constructed that demonstrates a tendency to decrease the share of the employed population in the total number of economically active population.

Published: September 2023

The subject of the study is the investment processes that arise during the implementation of Russia's social policy aimed at solving problems of improving the quality of life of society. The purpose of this study is impact investment, which is actively used for the implementation of social and environmental projects. Due to the fact that the dynamics of its volumes in the world in recent years has shown steady growth against the background of the developing global trends of the financial crisis, the objectives of the work are to establish the characteristics of the ecosystem of impact investment in Russia, to determine the factors constraining its development. Based on the analysis of the concept of impact investment, interpreted differently in the works of various authors, the main participants in the impact investment process are identified, criteria that distinguish transformative investment from other forms of money investment are identified. The author's model of the impact investment ecosystem is proposed, focused on the national architecture of the financial market. It is concluded that it is necessary to develop separate areas of methodological apparatus for impact investment analysis. It allows not only to describe the interaction of the main participants in this process and financial instruments, but also a system of specific assessment, which can subsequently be laid down as the basis for management decisions by investors and managers of socially significant social and environmental projects.
