Adsorption- and Displacement-Based Approaches for the Removal of Protein-Bound Uremic Toxins
Authors: Rodrigues Flávia S. C. , Faria Mónica
Published: January 2023

End-stage renal disease (ESRD) patients rely on renal replacement therapies to survive. Hemodialysis (HD), the most widely applied treatment, is responsible for the removal of excess fluid and uremic toxins (UTs) from blood, particularly those with low molecular weight (MW < 500 Da). The development of high-flux membranes and more efficient treatment modes, such as hemodiafiltration, have resulted in improved removal rates of UTs in the middle molecular weight range. However, the concentrations of protein-bound uremic toxins (PBUTs) remain essentially untouched. Due to the high binding affinity to large proteins, such as albumin, PBUTs form large complexes (MW > 66 kDa) which are not removed during HD and their accumulation has been strongly associated with the increased morbidity and mortality of patients with ESRD. In this review, we describe adsorption- and displacement-based approaches currently being studied to enhance the removal of PBUTs. The development of mixed matrix membranes (MMMs) with selective adsorption properties, infusion of compounds capable of displacing UTs from their binding site on albumin, and competitive binding membranes show promising results, but the road to clinical application is still long, and further investigation is required.

Diseases contribute to attainment of less than 50% of the local groundnut potential yield in Kenya. This study aimed to evaluate the agronomic characteristics (flowering and germination), disease incidence, yield performance (biomass, harvest index, 100-pod, 100-seed, and total pod weight), and aflatoxin accumulation in six peanut varieties. A field experiment was conducted using four newly improved peanut varieties: CG9, CG7, CG12, and ICGV-SM 90704 (Nsinjiro), and two locally used varieties: Homabay local (control) and 12991, and in a randomized complete block design with three replications. The disease identification followed the International Crop Research Institute for the Semi-Arid Tropics (ICRISAT) rating scale and further isolation of fungal contaminants was conducted by a direct plating technique using potato dextrose agar. The aflatoxin levels in the peanuts were determined after harvesting using the ultrahigh performance liquid chromatography and fluorescence detection (UHPLC-FLD) technique. ICGV-SM 90704 showed the least average disease incidence of 1.31 ± 1.75%, (P < 0.05); the lowest total aflatoxin levels (1.82 ± 1.41 μg kg−1) with a range 0.00–0.85 μg kg−1 for total aflatoxins and a range 0.00–1.24 μg kg−1 for Aflatoxin B1. The locally used varieties (12991 and the control) revealed the highest disease incidence (5.41 ± 8.31% and 7.41 ± 1.88%), respectively. ICGV-SM 90704 was the best performing among all the six varieties with an average total pod weight (9.22 ± 1.19 kg), 100-pod weight (262.93 ± 10.8 g), and biomass of (27.21 ± 5.05 kg) per row. The 12991 variety and the control showed the least total pod weight (1.60 ± 0.28 and 1.50 ± 1.11 kg, respectively) (P = 0.0001). The newly improved varieties showed lower disease rates, low levels of aflatoxins, and higher yields than the locally used varieties.

In March 2020, WHO declared Coronavirus Disease 2019 (COVID-19) as a global pandemic, which had a major impact on all mass gatherings (MG), including the Hajj. This has an impact for the government, as the party organizing the pilgrimage can make more mature preparations for a more optimal implementation of the pilgrimage. This study aimed to evaluate hygiene and health coaching for community readiness to perform the Hajj during an ongoing COVID-19 pandemic in Indonesia. We used a mixed qualitative and quantitative method, in which the quantitative component used an analytic cross-sectional design with a questionnaire given to 2425 pilgrims, while the qualitative component was carried out through Focus Group Discussion. During the pandemic, all hygiene and health coaching, including guidance, was carried out in three types of distance learning, called “online”, “offline (face-to-face)”, and “combination”. This study shows that face-to-face health coaching is low (50.5%), while online coaching is high (70.0%). The total fraction of pilgrims who participated in blended coaching sessions was 55.1%, and the highest frequency of coaching was under four times (38.7%). However, in its implementation, there is still no integration between programs. There is quite a lot of health information given to pilgrims, but the material still varies between regions. Information on guidelines for preventing and transmitting COVID-19 for officers and pilgrims has not been fully socialized. There exists an urgent need to establish messages that are clear, meaningful, empathetic, consistent, and in context in order to achieve health improvement of pilgrims.

Hydraulic Conditions of Incipient Rill by Raindrop-Induced Overland Flow on Steep Slopes of Sandy Soil
Authors: Shin Seung Sook , Park Sang Deog , Sim Young Ju , Ryu Jae Hyeon
Published: January 2023

Hydraulic characteristics of rill incipience on steep slopes with sandy soils are different from those of gentle slopes in the mountainous watersheds. In other to better understand the processes of the incision and expansion of rill, rainfall simulations were conducted in a laboratory soil box with an inflow device installed at the top of the steep slope. The location and shape of the rill incision were tested with respect to different slopes (20, 24, and 28°), rainfall intensity (80 and 100 mm/h), and segment distances with various inflow rates (0.0, 8.8, 17.5, and 26.3 ml/s). The result showed that rills with heatcut were mostly incised on the 2.4 m segments and progressively moved upslope on the 3.2 m segments. The steps of rill evolution with increase of inflow are identified as four stages; (1) sheet flow with impact of raindrops, (2) overland flow with flowpaths, (3) microrill with headcut incision, and (4) rill enhanced by headcut expansion. It appears that incision and headcut of rill is prevalent when the Froude number (Fr) changes from subcritical flow to supercritical flow and the maximum velocity of rill reaches over 0.065 m/s. Unit stream power using the maximum velocity of rill was the best parameter for estimating rill erosion as rill evolution greatly depends on maximum velocity of the local flow enhanced by rill incision and expansion As a result, it was found that critical conditions for rill incipient of sandy soils on steep slope are observed greater than those of loamy soils or gentle slopes.

Published: January 2023

Floods have caused major losses and damages to people, infrastructure, and the environment. This study aims to assess the risk perception of households prone to riverine and flash floods and the perceived damages to infrastructure and livelihoods. Data were collected from 382 households through a questionnaire survey and analyzed using chi-squared and t-tests. Overall, risk perception was higher for riverine floods. Similarly, ‘flood coping capacities’, ‘livelihood disruption’, ‘change in lifestyle/adjusting to floods’, and ‘change in the relationship’ were also high for riverine floods and statistically significant (p-value < 0.05). The ‘likelihood of future flood damages’ perception was higher for flash floods (mean values: 0.913 vs. 0.779), while the ‘infrastructural damages’ showed the same results. The perceptions of ‘livelihoods’ and perceived ‘economic loss’ were greater for riverine floods (p-value < 0.05). The perceptions of ‘livestock damages’ and ‘household damages’ were higher for flash floods.

Published: January 2023

The Paldang Reservoir (PDR) in South Korea is vital for supplying drinking water and maintaining ecosystems; thus, a comprehensive understanding of its water quality is necessary. Spatiotemporal changes in reservoir water quality were evaluated by applying Korean water quality indices and multivariate statistical techniques (MSTs). A dataset of 15 water quality parameters at five sites in the PDR were evaluated from 2017 to 2021. The organic matter, suspended matter, total phosphorus (TP), chlorophyll a (Chl-a), and total coliforms in the PDR exhibited a fair grade or higher. Chemical oxygen demand was found to correlate with biochemical oxygen demand, Chl-a, and TP. The average real-time water quality index (RTWQI) and average trophic state index (TSIKO) of the PDR were excellent and mesotrophic, respectively, and 46% of eutrophic conditions occurred during the monsoon season. For a hierarchical cluster analysis (HCA), the five sites were grouped into three polluted areas and 12 months were grouped into dry and wet seasons. Principal component analysis and factor analysis identified four potential pollution sources (domestic sewage, industrial wastewater, intensive agricultural activities, and livestock wastewater) in the PDR and explained 79.7% of the total changes. Thus, the RTWQI, TSIKO, and MSTs are useful tools for assessing freshwater quality in Korea, predicting potentially harmful conditions, and potentially assisting policymakers in PDR management.

Authors: Zhang Zhongwei , Zhou Liangjing , He Yunjiao , Luo Zhaohui , Chen Sibao
Published: January 2023

High-arsenic water limits the utilization and development of water resources in Tibet, and high-arsenic groundwater is one of the major sources of arsenic input to surface water in the area. In this work, the characteristics of groundwater and the source and formation of arsenic in a typical watershed in Tibet (the lower tributaries of the Angqu River) were investigated using systematic surveys, ionic ratios, Gibbs diagrams, in combination with isotopic and heat storage calculation methods. The studies show that the chemical composition of the water in the study area is mainly determined by the rock weathering of carbonate and silicate rocks. The average recharge elevation levels of hot spring water are 4874.1 m, 4058.1 m, and 4745.0 m, respectively. Deep hot water is the main source of arsenic in the spring water, and its arsenic flux accounts for 98.44–99.77% of the measured flux in the spring water.

Published: January 2023

There is a wide range of naturally regenerated Morus alba in the declining Robinia pseudoacacia plantation of the Yellow River Delta. It is important to clarify the key mechanism of natural regeneration of M. alba for the transformation of declining R. pseudoacacia plantation. According to the death density of R. pseudoacacia, the plantation of R. pseudoacacia was divided into nondeclining, moderately declining, and severely declining forests. The structural characteristics of adult trees and seedlings of M. alba in different decline degrees forest were investigated. A pot experiment was conducted to study the seed germination and early seedling growth of M. alba in saline alkali soil and nonsaline alkali soil under different soil salt contents and light intensities. The results showed that the natural regeneration of M. alba was obviously affected by the decline of R. pseudoacacia plantation. With the increase of decline degree, M. alba density and seedling density first increased and then decreased, and were the highest in the medium decline plantation. Under full light intensity, the vigor index of M. alba seeds and the biomass of seedlings were significantly greater than those of 25% full light intensity. The germination rate and germination index under 1‰ soil salt content were significantly lower than those under 3‰, but the biomass of seedlings was on the contrary. The 1000-seed weight, seed germination, and seedling biomass of moderately declining R. pseudoacacia plantations were close to those of nonsaline alkali land, while significantly higher than those of nondeclining plantations, but the germination index of moderately declining R. pseudoacacia plantation was higher than that of nonsaline alkali land. Therefore, the germination ability of maternal trees in saline alkali land was higher than that in nonsaline alkali land under salt stress.

Endometriosis Awareness Month on Social Media: A Content Analysis of Images and Captions on Instagram
Authors: Le Busque Brianna , Mellish Sarah
Published: January 2023

Endometriosis Awareness Month (EAM) is a global movement that seeks to increase awareness of endometriosis. There is a paucity of peer-reviewed research that explores the social media activity of EAM, making it difficult to draw conclusions about what information is being shared. To address this gap, we performed inductive thematic analysis to investigate the visual and written content of images (n = 879 images), as well as post captions of N = 600 posts. that contained the hashtag “#endometriosisawarenessmonth”. Results show that written content within the images most frequently contained features of the disease. Caption content featured general/vague knowledge about the disease and general awareness of endometriosis, such as ‘pain (general/unspecified)’. The mental health impact of the disease was underrepresented in Instagram posts. Moving forward, the #endometriosisawarenessmonth campaign could be strengthened by communicating specific diagnostic and prevalence information, and harnessing conversations about the impact of the disease on mental health.
Zn3(PO4)2 Protective Layer on Zn Anode for Improved Electrochemical Properties in Aqueous Zn-ion Batteries
Authors: Kim Chae-won , Choi Junghee , Choi Jin-Hyeok , Seo Ji-Youn , Park Gumjae
Published: January 2023

Aqueous zinc-ion batteries are considered as promising alternatives to lithium-ion batteries for energy storage owing to their safety and cost efficiency. However, their lifespan is limited by the irreversibility of Zn anodes because of Zn dendrite growth and side reactions such as the hydrogen evolution reaction and corrosion during cycling. Herein, we present a strategy to restrict direct contact between the Zn anode and aqueous electrolyte by fabricating a protective layer on the surface of Zn foil via phosphidation method. The Zn3(PO4)2 protective layer effectively suppresses Zn dendrite growth and side reactions in aqueous electrolytes. The electrochemical properties of the Zn3(PO4)2@Zn anode, such as the overpotential, linear polarization resistance, and hydrogen generation reaction, indicate that the protective layer can suppress interfacial corrosion and improve the electrochemical stability compared to that of bare Zn by preventing direct contact between the electrolyte and the active sites of Zn. Remarkably, MnO2 || Zn3(PO4)2@Zn exhibited enhanced reversibility owing to the formation a stable porous layer, which effectively inhibited vertical dendrite growth by inducing the uniform plating of Zn2+ ions underneath the formed layer.

Published: January 2023

Schreibkompetenz gehört zu den produktiven Fertigkeiten, über die Studierende des Faches Deutsch als Fremdsprache (DaF) für die schriftliche Kommunikation und wissenschaftliche Zwecke in Form von schriftlichen Texten verfügen müssen. Während die Weiterentwicklung von Schreibfähigkeiten wie Vorschreiben, Organisieren, Entwerfen und Ausarbeiten sicherlich ein wichtiges Ziel für Bildungseinrichtungen auf allen Ebenen ist, stellt dies auch eine große Herausforderung für Lehrende und Lernende dar, insbesondere im Fremdsprachenunterricht. Ziel dieser Arbeit ist daher es, die akademische Schreibkompetenz in der Fremdsprache Deutsch angehender türkischen Deutschlehrer an der pädagogischen Fakultät der Anadolu Universität zu untersuchen. Damit wird die Forschungsfrage der vorliegenden qualitativen Arbeit aufgestellt, wie die akademische Schreibkompetenz der Studierenden beurteilt werden kann. Zur Beantwortung dieser Frage ist auf der ersten Ebene die wissenschaftliche Schreibkompetenz der Studierenden einzuschätzen. Die zu einer bestimmten Frist selbstgestalteten Aufgaben von Probanden werden aus der Sicht der qualitativen Herangehensweise und der Inhaltsanalyse nach ihrem Textinhalt, Textaufbau und der angewendeten Sprache hin untersucht, kodiert, nach dem Ziel der Forschung nochmals rekonstruiert und nach ihren Oberbegriffen zusammengefasst. Ausgehend von den Ergebnissen lässt sich die Hypothese formulieren, in wieweit die Studierenden notwendige akademische Schreibkenntnisse besitzen und von welchen Strategien sie während der Bearbeitung ihrer eigenen produzierten Texte heranziehen. Aus dieser Studie ergibt sich des Weiteren die Schlussfolgerung, dass die Studierenden über das Wissen zum Verfassen wissenschaftlicher Texte verfügen, aber Unterstützung beim Verfassen wissenschaftlicher Texte benötigen. Schreiblabore und auch Seminare diesbezüglich, in denen Tutoren oder Postgraduierte zusammenarbeiten und Hilfestellung anbieten, könnten die Schreibfähigkeiten der Studierenden fördern.

general anesthesia for lower abdominal surgery in children
Authors: Tran Xuan Thinh , Nguyen Trung Dung
Published: January 2023

Background: Both laryngeal mask airway I-gel and Supreme have been available for clinical use, but there was no comparison between two devices. This study was designed to compare the efficacy and complications of the laryngeal mask airway I-gel and Supreme in children undergoing general anesthesia for lower abdominal surgery. Methods: One hundred and twenty children were randomly assigned to either the I-gel or the Supreme group (60 children in each group). All patients of the two groups received the same protocol of general anesthesia. Evaluation criteria included successful mask insertion rate, ease of insertion, insertion time, and number of adjustments needed during anesthesia maintenace and postoperative complications. Results: There were no differences in the demographic data between the two groups. The success rate of insertion in the first attempt of the I-gel group was 94.8% and the Supreme group (98.3%) (p>0.05). According to ease of placement, grade 1 (very easy) ratios of Supreme, and I-gel were 40% and 3.3%, respectively (p<0.01). The insertion time of the I-gel was longer than that of Supreme (p < 0.05). The rate of airway manipulations during anesthesia maintenance of Supreme, and I-gel group were 5% and 11.7%, respectively (p > 0.05). The most common complication was cough, with the rate of 17% in I-gel group and 5% in Supreme group (p<0.05). There were no differences in other complications between both groups. Conclusions: Both I-gel and Supreme provided a satisfactory airway during general anesthesia in children. Insertion of Supreme was significantly easier and more rapid than insertion of I-gel, and the incidence of cough after surgery was significantly lower with Supreme than I-gel.

Introduction: The coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), has caused effects on cancer patients including cancer screening process, risk factor records, cancer diagnoses, cancer treatment and follow-up. Nowadays, the COVID-19 vaccine has been used around the world and it has resulted axillary lymphadenopathy reaction. Unilateral axial lymphadenopathy which located near the vaccine injection site following COVID-19 vaccination is common of expecting adverse reaction especially happened in mRNA vaccine (Pfizer-BioTech and Moderna). In this COVID-19 pandemic, physicians should be aware of this follow-up process to avoid false positive cancer diagnosis and inform patient of unnecessary investigation, or delayed cancer diagnosis because suspected COVID-19 vaccination reaction instead of cancer diagnosis. Case report: We present two cases of a 47-year-old female and 34-year-old with no medical history, admitted to Department of Breast and Gynecologic cancer, Danang Oncology Hospital because of axillary lymphadenopathy that occurred after COVID-19 vaccination. Conclusion: After reviewing the literature, ipsilateral injection side axillary lymphadenopathy has been reported. Therefore, physician as well as oncologist working in the era of COVID-19 should be obtained information regarding COVID-19 vaccination including injected time, injected arm, and the symptoms after vaccinating to ensure the accuracy diagnosis and to avoid unnecessary biopsy and the possibility of a misdiagnosis. We recommend to perform cancer screening before vaccination or consider delay breast cancer screening exams until 4-6 weeks after vaccination, and the patient can undergo short term follow-up in the three months to ensure resolution.

CONSTRUCTION WITH A U-SHAPED PROFILE GRILLE
Authors: Марутян А. С.
Published: January 2023

Приведен сравнительный расчет оптимальных параметров стержневых элементов из V- и U-образных профилей. Оба они оптимизированы по критерию равноустойчивости. Первый получен в результате раскрытия полок равнобокого уголка на угол, меньший прямого, и применен в качестве прототипа для второго. U-образный профиль состоит из двух вертикальных стенок, соединенных круглым полукольцом, и отличается отношением габаритных размеров ширины и высоты 1/1,39 по средней линии его расчетного сечения. Тестирование приближенной методики расчета подтвердило ее необходимую и достаточную корректность, остающуюся в пределах погрешностей конечно-элементного моделирования. Результаты расчета показали, что при одинаковом расходе конструкционного материала U-образный профиль более предпочтителен, поскольку его размеры компактнее, а ресурсы несущей способности больше.

A comparative calculation of the optimal parameters of rod elements from V- and U-shaped profiles is given. Both of them are optimized according to the criterion of equidistance. The first one was obtained as a result of opening the shelves of an equilateral corner by an angle smaller than a straight one, and was used as a prototype for the second one. The U-shaped profile consists of two vertical walls connected by a circular semicircle, and differs in the ratio of overall dimensions of width and height 1/1.39 along the middle line of its design section. Testing of the approximate calculation method confirmed its necessary and sufficient correctness, remaining within the limits of errors of finite element modeling. The results of the calculations showed that with the same consumption of structural material, the U-shaped profile is more preferable, since its dimensions are more compact, and the load-bearing capacity resources are greater.

El presente trabajo tiene como objetivo promover un análisis sobre el tema de "vivir" desde la perspectiva de un Servicio Residencial Terapéutico (SRT) y una Unidad de Recepción de Adultos (UAA). Considerando que se trata de dispositivos estratégicos para el avance de los procesos de desinstitucionalización y reforma psiquiátrica, creemos que los debates y estudios sobre este tema son urgentes y necesarios. Partimos de la hipótesis de que los entendimientos y significados en torno a "vivir" afectan directamente a la conducta clínica de los casos. Para este análisis, se utilizó principalmente la técnica del Grupo Focal, realizada con diferentes profesionales de un SRT y un UAA del municipio de Río de Janeiro. A partir de esta investigación, se espera que uno de los posibles resultados pueda ser una mejor comprensión de cómo los profesionales de un SRT y un UAA entienden estos dispositivos, así como un mayor conocimiento sobre los impactos de estos servicios en la red de atención psicosocial y en los territorios en los que se encuentran. En términos más generales, también se espera que contribuya al debate sobre el papel estratégico de estos espacios de vida en la atención psicosocial.
Caste studies today
Authors: Shah Prakash
Published: January 2023

Starting with an individual report in a leading British periodical of higher education, this article fans outwards to show how the contemporary field of caste studies reflects the degeneracy of its methods and claims. Rather than producing knowledge about India and the so-called caste system, caste studies has worked itself into a corner by creating a set of imagined victims and perpetrators of caste oppression, atrocities, violence and discrimination, and by making unsustainable claims on legal systems and other institutions. The manifold and insurmountable problems of contemporary caste studies include its basis in the European framework for the study of India founded upon Christian theological claims, the carry-over of this account into the secularised humanities and social sciences, and its engagement in corrupted academic practices of the kind that typify grievance studies today. That an alternative account exists in the form of the research programme of SN Balagangadhara, which inspires the articles in this special issue, is good reason for rethinking and revision of the field.

A Public Value Approach to Analyzing and Intervening in National Educational Systems
Authors: Moore Mark , Spivack Marla
Published: January 2023

Any analysis of a “National Educational System” reveals a highly complex social production system that is neither a hierarchical organization, nor a market, nor simply a misaligned system of principals and agents. It is, instead, a complex array of social actors bound together through various social structures and processes on one hand, and important functional relationships on the other. In approaching the challenge of moving that system towards sustained productivity gains, national governments naturally fall prey to the assumption that, in the principal/agent framework they are the principals of the system. But, as we have seen empirically, this idea overestimates the capacities of most central governments in developing countries (Pritchett 2013, Pritchett 2015, Moore and Spivack 2022). The world at large has learned that it is hard to centrally manage complex economies to produce economic prosperity and social equity. It is not obvious that the search for educational improvement is any less difficult. Of course, it is not wrong to imagine that the national government can become an important catalyst, motivator, and director of the system that will enhance its productivity – broadly understood. The important question, however, is how exactly it should practically do so? How can the central government develop a “strategic capacity” that can keep the widely distributed system as a whole moving towards improved performance with respect to both educational goals, and the wider economic, social, and political purposes that a polity hopes to advance through the provision of educational services. Answering that question for a broad class of national governments seeking to promoted sustained educational productivity relative to their goals is the task we will tackle in this essay (Moore and Spivack 2022).

Introdução: Os contraceptivos orais combinados (COCS) são usados há bastante tempo pela população feminina, porém o estrogênio contido nas pílulas mais comumente usadas apresenta alguns efeitos colaterais importantes. Atualmente, estudos buscam inserir o estetrol nas pílulas contraceptivas, tal composto é um novo tipo de estrogênio que promete reduzir os efeitos adversos do estrogênio presente nos COCS. Objetivo: Destacar os benefícios do estetrol que o torna mais vantajoso quando comparado ao estrogênio contido nas pílulas já existentes. Método: O presente artigo será uma revisão sistemática, onde serão utilizadas as seguintes plataformas: Biblioteca Nacional em Saúde (BVS), National Library of Medicine (PUB- MED). Os Descritores em Ciências da Saúde (DeCS): Anticoncepcionais orais, estetrol e estrogênios. Os artigos aceitos serão os realizados nos últimos 5 anos, em idioma inglês, e que tenham relevância para o tema. Resultados e Discussões: Diante do exposto a respeito dos resultados obtidos, os contraceptivos orais combinados (COCs) são compostos por um estrogênio e uma progestina, tal combinação é responsável pelo efeito contraceptivo das pílulas. Conclusão: Então concluímos que é importante que tenha mais estudos sobre as vantagens do estetrol frente aos outros estrogênios das pílulas contraceptivas, pois não vemos o suficiente para podermos ter uma visão ampla.

FEATURES OF THE APPLICATION OF COMPULSORY TREATMENT TO PERSONS WHO COMMITTED CRIMINAL ACTS IN THE FIRST YEARS OF SOVIET POWER
Authors: Golikova O.A.
Published: January 2023

The article considers the main problems associated with the formation of measures of a compulsory medical nature of the first years of Soviet power from 1918 to the mid-1930s. It was noted that it was during this period of time that the most complex processes occurred due to the need to form a new approach to understanding compulsory treatment. It was determined that the problems were associated not only with the process of developing a holistic right position on the concept and definition of the essence of insanity and the need to apply isolation, but also with the process of practical implementation. Features of the formation of measures of compulsory treatment at different stages of development are highlighted. Initially, the policy was characterized by the temporality and instructiveness of a legal approach focused on punitive methods. In the 1920s there was a transition to social protection measures. In the 1930s there was a clear legal division of competencies between law enforcement and medical authorities in the matter of making a diagnosis and making a decision on the appointment of measures for compulsory treatment, regulated by the 1935 Instruction and based on a scientific approach. The results of the legal development of the Soviet state in the first decades of its existence regarding compulsory treatment against persons who committed criminal acts were summed up. The methodological basis of the work was the formal-legal method, which made it possible to conduct a comprehensive analysis of the legal acts of the period under consideration, the historical and legal method helped to trace the peculiarities associated with the formation of the legal approach of the state in relation to insane persons.
THE COMPLEX OF CONTRACTUAL CRIMINAL PROCEDURAL FORMS OF THE END OF A CRIMINAL CASE
Authors: Kolesnik V.V.
Published: January 2023

The article is devoted to the problem of systematization of criminal procedural forms of termination of criminal cases on a number of non-rehabilitating grounds, which are called dispositive or conciliatory-compensatory, form a certain system. Its goals are to promote the shift of the doctrine towards the recognition of the contract as a completely normal way of resolving criminal procedural issues, as well as the development of the foundations of the author's concept of contractual criminal procedural forms of ending a criminal case. The main methods of legal cognition were used: deduction, induction, analysis and others. As a result of the research, the general provisions forming the basis of the author's concept were derived. These included provisions on the accomplices of the agreement on the termination of the criminal case with the accused on the termination of the criminal case by the prosecution, the subject of the agreement, the principles of the agreement. It is proposed to strengthen the role of the prosecutor in contractual procedures for the termination of criminal cases and to make the participants from the prosecution responsible for drafting the terms of the agreement and overseeing their execution. The range of grounds for contractual criminal procedural proceedings is currently provided for in Articles 25, 25.1, 27 Part 3, 28 Part 2, 28.1, 427 of the Code of Criminal Procedure of the Russian Federation. The author suggests expanding it with the basis of a change in the situation or loss of social danger to the accused in the course of his cooperation with the investigation and the prosecutor.
