Authors: KUTLUATA Nazif Özgen , OLGUN Çağrı , GÜR Mahmut
Published: November 2023

The aim of this study is that determination of the usability of the different types of waste impregnated papers (IP) in a standard HDF production line. For this purpose, the HDF panels were produced from industrial prepared fibers and waste of IP, called decor and overlay, preparation lines by three different ratios (from 5% to 15%). Some important properties of HDF’s were determined according to standard test methods and were evaluated by statistical analysis in a 95% confidence interval. According to the evaluation results, it was concluded that it is possible to statistically evaluate the use of overlay and decor papers up to 15% in a standard production in terms of density, and equilibrium moisture, thickness swelling (2 h and 24 h), and modulus of rupture values. In addition, it was observed that the modulus of elasticity and tensile strength values generally improved as the amount of waste paper increased, regardless of the type of waste paper. However, the significant increase in formaldehyde emission showed that evaluating these waste papers without changing in the standard production line is difficult.

Authors: Latifah Ani , Zulaiha Zulaiha
Published: November 2023

This study aims to answer why some students are more successful than others in mastering a second language and why one person seems to learn faster than the other even though both are in the same situation. This research is qualitative descriptive. The researcher interviewed five English teacher to find out the difference in the ability of students to master the second language, from those who only attended formal learning at school and took part in informal learning outside of school. The question consists of five questions. Because second language acquisition (L2) is a very complex process, there is no model that captures all its aspects. The researcher summarized the results of interviews with five English teachers, because the results of the interviews were almost the same. Based on the results of the study, it shows that students who only attend formal learning at school are different from students who are also supported by informal learning outside of school. Like taking a course, and also helping parents. Students who only study the second language at school will be slower in the process of obtaining a second language.
On the Issue of the Formation of the National-Personnel Policy of the Party Administration Apparatus of 1921–1930 (Based on the Materials of Party Congresses, Conferences and Plenums)
Authors:   Stavropol State Agrarian University, Tufanov Evgenii V.
Published: November 2023

The article scrutinizes the role of national personnel policy of the Soviet administrative apparatus based on the materials of the party forums. The study of national and personnel policy is one of the relevant tasks of modern historical science, since the decisions of the Soviet management system as part of the national and personnel policy were far from unambiguous and many of today's problems in the field of interethnic communication are rooted in the Soviet past. Thus, the national and personnel policy of the Soviet management system must be considered and evaluated in the aggregate, since they are different facets of one state issue. The novelty of the study is due to the pooled analysis of the national and personnel policy of the administrative apparatus of the Soviet state. National policy issues were addressed through the prism of personnel transformations. The issues of national personnel policy were reflected in all party forums. Consequently, it is the training of representatives of national minorities that has become the solution to all interethnic problems for the state authorities. Since the collapse of the country, the national issue in a number of regions of the former USSR has become one of the key issues and the cause of many conflicts. Therefore, the analysis of the national personnel policy of the So-viet state and the system of decision-making by the management apparatus is of practical importance for the modern manager.
The Political Situation in the Yakut Region on the Eve of the October Stage of the 1917 Revolution
Authors:   M.K. Ammosov North-Eastern Federal University, Radchenko Natalya N.
Published: November 2023

For the first time in a separate study, the scientific article examines the political situation in the Yakut region on the eve of October 1917. The alignment of political forces in the region that emerged in the fall of 1917 is char-acterized. After the departure of the political exiles, power passed into the hands of the Socialist Revolutionar-ies and Federalists. As in the center of the country, moderate socialists were in power in the Yakut region. In the fall of 1917, disagreements between the Socialist Revolutionaries and Social Democrats intensified, and a “united democracy” was created without the participation of the Council of Workers’ Deputies and the Social Democrats who supported it. Further development of the conflict led to the withdrawal of the Social Democrats from the Yakut Committee of Public Safety. The scientific article concludes that the development of the political situation in Yakutia is associated with the remoteness of the region and the peculiarities of its pre-revolutionary history. In the region, the united organization of the RSDLP operated until 1918. Local Bolsheviks and Menshe-viks supported Soviet power, but their forces were too weak. In this regard, the political conditions for the estab-lishment of Soviet power in the Yakut region on the eve of October 1917 did not exist.

Authors:   T.F. Gorbachev Kuzbass State Technical University (KuzSTU) (branch), Evsina Tatiana A.
Published: November 2023

Modern Russian society is experiencing a severe spiritual and moral crisis, during which value attitudes are being destroyed through the denial of traditional Russian values and the introduction of new value paradigms. Spiritual and moral crisis is a result of the crisis state of today’s Russian society, which is caused by many rea-sons: it is the instability of the economic component, and the constantly emerging political cataclysms in the world arena, and large-scale environmental problems, as well as the gaining momentum in the process of de-struction of social ties, and, as a consequence, the apparent destruction of moral foundations. The problem of preserving national identity is outlined at all levels, but its solution is possible only through the formation and strengthening of patriotism as the foundation of Russia’s future. That is precisely why the formation of patriot-ism becomes a priority of the Russian Federation’s state policy and is seen as a factor in preserving national identity.

Published: November 2023

The article provides a comprehensive analysis and conceptualization of the concept of “digital transformation” by considering it in the context of social and economic changes in modern society. The process of digitalization is presented as a consequence of society’s transition to a post-industrial society, in which knowledge and in-formation become the fundamental resources, and technocrats and highly qualified specialists occupy key positions. It is emphasized that digital transformation carried out by people and for people stresses the im-portance of analyzing its implications for society. Based on the analysis of various sources of literature and the use of methods of analysis, synthesis and induction, the article concludes that it is necessary to adapt to new realities, where the digital maturity of the population and its openness to new technologies become the deter-mining factors of progress. Attention is also focused on changes in public administration, which should become more open and citizen-oriented. In conclusion, the article summarizes the results, which emphasize the com-plexity and versatility of the digital transformation process and draw attention to the need for active participation of society and its readiness for change for the successful realization of the potential of digital technologies.

Annually the number of rural settlements in Russia is decreasing, at the same time the number of rural areas without inhabitants is increasing. There are a sufficient number of factors influencing the reduction of rural set-tlements. But in our opinion, the most significant negative impact is exerted by the low level of remuneration of workers in the agricultural sector of the economy, as well as the very specifics of agricultural labor. The prob-lem of youth outflow, which is directly related to the lack of attractive social infrastructure in rural areas, has not been solved yet. To ensure staffing needs, a mechanism of sustainable reproduction of agricultural personnel is a necessary condition. Macro-environment factors have a significant impact on the nature of personnel re-production processes, since they largely determine the conditions for decision-making by participants in the reproduction process. The labor resources of the agricultural sector are characterized primarily by lower quality relative to other sectors of the economy. The reduction in the number of agrarian personnel, inconsistency in the qualitative structure of personnel cannot fully ensure the competitiveness of the industry, as well as fully realize the tasks facing the multi-structure agriculture-based economy. The article highlights the features of the process of reproduction of personnel in rural areas, which will allow structuring analytical data in the analysis of the system of reproduction of agricultural personnel. The aim of the present article is to develop a methodology for analyzing and systematizing the factors of the macro-environment of personnel reproduction. The study applies the methods of STEP-analysis and STEEPLE-analysis. The scientific novelty of this study lies in the systematization of macro-environment factors that affect the reproduction of rural personnel, based on which the methodology of three-level analysis is substantiated. The practical significance of the results obtained lies in the systematization of the factors of personnel reproduction in rural areas, based on Russian studies and taking into account, in particular, the size and socio-economic heterogeneity of territories. The result of the study is the identification, justification and systematization of macro-environment factors that influence the re-production of personnel in rural areas.

The activities of non-profit organizations are an important aspect in the development of civil society. State sup-port of non-profit organizations in Russia in the period from 2010 to 2023 has received its systematic develop-ment. The role of state support for socially oriented non-profit organizations is high and ensures the stability of the development of the non-profit sector in Russia during the economic crisis. In 2014 and in 2022, Russia in-corporated 6 new constituent entities of the Russian Federation. Their economic and legal integration is a key task for regional and federal authorities. The participation of non-profit organizations in the implementation of social policy on the ground allows to achieve the goals in this regard more effectively. This article analyzes the forms of state support for socially oriented non-profit organizations in the territory of new regions (Donetsk People’s Republic, Republic of Crimea, Luhansk People’s Republic, Zaporozhye region, Kherson region, fed-eral city of Sevastopol), as well as their degree of influence on the development of the non-profit sector. For the first time, the study analyzed the indicators of all forms of state support for socially oriented non-profit struc-tures, including financial, property, organizational-administrative and informational-advisory in relation to the new constituent entities of the Russian Federation.

Bufo verrucosissimus is an endangered species in the Russian Federation. One of the largest protected areas where B. verrucosissimus is preserved is the Caucasian State Nature Biosphere Reserve. The paper presents data on age structure and growth of B. verrucosissimus collected in the Caucasian State Nature Biosphere Reserve in 1987–1990 and stored in the collection of Sochi National Park. The age of 16 females and 51 males was determined using the method of skeletochronology. The age of adult females was 6–10 years (on average 7.9 years), and males 2–9 years (on average 5.8 years). Females were statistically significantly superior to males in average age. In terms of body length, significant differences between males and females where noted in groups of seven- and ten-year-old animals. The body length of studied animals (60.8–116.4 mm for females and 61.2–86.3 mm for males) corresponds to the size of adult toads from other localities in the North Caucasus. Females grow evenly throughout their lives, while the growth of males slows down significantly after reaching puberty. Males were able to reach the maximum body length faster than females (the growth coefficient was 0.722 for males and 0.163 for females). According to the von Bertalanffy equation, the maximum possible body length was 130.9 mm for females and 74.6 mm for males.

Pelayanan kesehatan sudah dikenal sejak berabad-abad yang lalu. Upaya tersebut bukan hanya untuk mengobati atau menghilangkan penyakit saja, tetapi juga harus disertai dengan rasa puas dan nyaman bagi orang sakitnya. Untuk bisa mencapai upaya tersebut, pelayanan kesehatannya harus mengandung dua unsur, yaitu biomedis dan etika. Yang dimaksud dengan biomedis itu adalah kemampuan dokter untuk membuat diagnosis yang benar, alternatif terapi yang yang tepat dan aman, serta prognosis yang baik, sedangkan yang dimaksud dengan etika adalah niat, sikap dan perilaku dokter yang sabar, jujur dan ikhlas serta penuh empati dalam menangani pasiennya. Dalam perkataan lain, dokter itu harus bertindak profesional. Telah disepakati bahwa tonggak ilmu kedokteran modern dimulai dua setengah abad yang lalu, pada saat Hippocrates memperkenalkan tradisi luhur yang menjadi ciri dan pedoman bagi perilaku para dokter. Praktik kedokteran, dari dahulu sampai sekarang. Selain harus mempunyai kompetensi klinik (ekspertis) yang baik, juga selalu dipandu berdasarkan prinsip etika. Dua di antaranya, adalah nil nocere(do not harm) dan bonum facere(do good for the patient). Prinsip ini, setelah melalui berbagai penyesuaian dan penyempurnaan, tetap berlaku sampai sekarang. Sekarang pun, para lulusan kedokteran, diwajibkan mengucapkan Sumpah Dokter pada saat diwisuda dan diberi pedoman yang harus ditaatinya, berupa Kode Etik Kedokteran Indonesia(KODEKI)1 dan Petunjuk Teknis Praktek Kedokteran.

Published: November 2023

Promising materials to reduce the use of chemical compounds in cultivation are natural biomaterials. Chitosan and sodium alginate were subjected to a Co-60 gamma treatment in this research. Different concentrations of chitosan (300 ppm), sodium alginate (500 ppm), and a mixed solution (90:10 irradiated Na-alginate: chitosan) were administered through foliar spraying with intervals of 15 and 30 days to observe the impacts on growth and anti-fungal activity. The growth attributes like total number of leafs, productivity of growing and mature leafs and anti-fungal activities were determined up to five months. When sprayed 15 days apart, the mixed solution was found to increase the output of pineapple plants and the height of mature leaves, whereas sodium alginate was found to increase the productivity of growing leaves when sprayed at 30-day intervals. The findings showed that sodium alginate and chitosan that had been irradiated both significantly improved productivity and decreased total fungal count.
Environmental racism and environmental injustice: Decolonial inflections and new agendas in Latin America and Brasil
Authors: Rougeon Marina , Mota Clarice , Trad Leny
Published: November 2023

The idea of environmental racism has been gradually gaining visibility in the Brazilian environmental agenda after its emergence in the United States. It is present in academic narratives and environmental activism, generally associated with the concept of environmental injustice and based on political ecology, which has been occupying a prominent position in Latin America. We propose to discuss this concept without pretending to be exhaustive, considering its origin, trajectory, uses, controversies, and limits. We make a parallel between the U.S. and Latin America, underlining some common elements but also the differences in terms of posture, especially in the face of colonialism and capitalism. Then our attention is drawn to the Brazilian case, analyzing some peculiarities of the justice-injustice-environmental racism interface. Finally, we underscore the alternative horizons opened by this issue, based on local life models, ontologies, and cosmologies that increasingly find a prominent place on the environmental agenda, notably discussing the issue of human rights, the rights of nature and territories. In this article, the central ideas presented are guided by a critical and decolonial-inspired analysis of environmental issues.
The hidden and complex relationship between dietary phosphorus and malnutrition in hemodialysis patients with chronic kidney disease
Authors: Milla Clonia , Widodo  , Wardhana Teddy Heri
Published: November 2023

Introduction:

Chronic kidney disease (CKD) has always been a complicated global challenge, ranking as the 12th leading cause of death worldwide. Hemodialysis, being one of the most opted renal replacement therapies (RRTs) for patients with end-stage renal disease (ESRD), still possesses some limitations in preventing complications, such as malnutrition and mineral bone disease (CKD-MBD). While efforts have focused on controlling CKD-MBD parameters like calcium and phosphate, less attention has been given to dietary interventions. Moreover, the adoption of low-phosphorus diets for hemodialysis patients is very complex due to potential conflicts with the guideline-recommended high-protein dietary approach. This study sought to investigate the relationship between dietary phosphorus intake and nutritional status in CKD patients undergoing regular hemodialysis.

Method:

This non-randomized cross-sectional study comprising 88 patients was conducted at the Hemodialysis Unit, RSUD Dr. Soetomo, Surabaya, East Java, using a three-day dietary record in March 2022. Relationships between variables were analyzed using Spearman and ANOVA tests.

Result:

No significant positive association was found between dietary calcium with corrected calcium levels (p = 0.988; rs = −0.002) and between dietary phosphorus with plasma phosphate levels (p = 0.082; rs = 0.187). However, Spearman's analysis revealed a weak but positive correlation between dietary phosphorus and nutritional status (p = 0.022; rs = 0.215*).

Conclusion:

Our study highlights a positive relationship between dietary phosphorus and nutritional status among hemodialysis patients, offering insights into potential strategies for optimizing patient care and outcomes.

Objetivo: Avaliar o efeito de um programa de treinamento multicomponente em octogenários hipertensos com relação à aptidão física e qualidade de vida. Métodos: Ensaio clínico controlado aleatorizado aprovado pelo Registro Brasileiro de Ensaios Clínicos (ReBEC) em que os octogenários hipertensos foram alocados em grupo intervenção (GI, n=14, idade média de 82,6± 2,31 anos) ou controle (GC, n=18, idade média de 84,1±3,06 anos). O GI foi submetido a um programa de exercício físico multicomponente por 12 semanas, já o GC recebeu aconselhamento e orientações de autocuidado com a saúde. Ambos os grupos foram submetidos a testes metabólicos e físicos e responderam ao questionário sobre fragilidade e ao 36-Item Short Form Survey (SF-36) no início e no final da intervenção. Resultados: No GI houve redução da pressão arterial (p=0,050), melhorias na força (p<0,001) e equilíbrio (p<0,001). Foram verificadas melhorias no SF-36 em capacidade funcional (p<0,040) e estado geral de saúde (p=0,007) entre os grupos. Conclusão: O programa de treinamento multicomponente aplicado reduziu a pressão arterial e melhorou a capacidade funcional e o estado geral de saúde. Essa melhora pode ser eficaz para manter a força e recuperar a capacidade dos octogenários hipertensos de realizar atividades da vida diária de forma mais independente.

Objectives:

Musculoskeletal injuries (MSKI) have been one of the most common contributors to disabilities among aircrew. The existing policy mandates all cases of MSKI in aircrew of the Indian Air Force, including minor injuries such as a sprain of small joints and phalangeal fractures to be evaluated at the Institute of Aerospace Medicine (IAM), majority of which do not warrant a complete Human Engineering (HE) assessment. Hence, a need was felt to decentralize evaluation and empower other boarding centers/operational bases with local aerospace medicine specialists to carry out the evaluation.

Material and Method:

A retrospective analysis was carried out of a total of 930 cases of MSKI among serving aircrew who reported to IAM between Jan 2016 and Oct 2020.

Results:

About 27.68% of cases were of lower limb injuries and 16.52% of cases were of upper limb injuries. About 36.77% of cases of upper limb and 52.71% of cases of lower limb injuries were treated surgically while 63.23% upper limb and 47.29% lower limb injuries were managed conservatively. Full functional recovery within 12 weeks was seen in a significant number of conservatively treated distal upper and lower limb injuries not involving joints.

Conclusion:

HE assessment of MSKI at IAM is comprehensive including exposure to simulated aeromedical stressors. However, certain minor musculoskeletal disabilities did not require full HE evaluation and simulator facilities of IAM. Sending aircrew with such minor disabilities from field units to IAM amounts to an administrative obligation that can be avoided by empowering other medical boarding centers and local operational bases which have aerospace medicine specialists. This paper discusses the procedure of conduct and facilitation of aeromedical evaluation of aircrew in the non-flying medical category with certain minor MSKI in the field.
Retrospective analysis of medical information records for 6 years of a national carrier in a Middle East country

Objectives:

Flying as a passenger without any disease or disability in a commercial airline poses no threat to the carrier or the passenger. People with diseases travel from one part of the country to another part or a different country for better treatment is called medical tourism. Patients with diseases are exposed to various stresses of aviation such as hypoxia, noise, vibration, and effects due to the expansion of gasses. Every airline has medical information form (MEDIF) form for all ill or incapacitated passengers.

Material and Methods:

Systematic analysis of medical information of a National carrier of a Middle East country was done for the past 6 years. A total of 44346 MEDIF forms were cleared from January 1, 2013, to December 31, 2018. One for every 665 passengers and 0.13 per flight. More than half of the request was from male passengers.

Results:

Most MEDIF passengers requested wheelchair holding till the cabin. It was 62.46%. The musculoskeletal system was the most frequently affected in the requested MEDIF Form. It constituted nearly 41% of all the MEDIF cases. Stretcher cases constituted 8.2% of all MEDIF cases.

Conclusion:

Results from the study threw light on the systems frequently affected by MEDIF clearance and the necessary precautions to be taken before clearing the MEDIF cases.

We report herein a simple, yet unexpected approach to dramatically improve the efficiencies of radical fluorination reactions of C(sp3)−H bonds. H−TEDA(BF4)2 is readily generated as a byproduct during fluorination reactions with Selectfluor®, the world’s most popular organic fluorination reagent. However, H−TEDA(BF4)2 to date is overlooked and discarded as waste, despite comprising 95% of the M.W. of Selectfluor®. We demonstrate that the addition of H−TEDA(BF4)2 at the start of fluorination reactions markedly increases their rates, outcompeting side reactions to access higher overall yields of fluorinated products. Showcasing the generality of the phenomenon, the performance additive enhances both photochemical/photocatalytic and thermal radical fluorination reactions by decreasing a discovered induction period in the former and by increasing the rate in the latter. Detailed mechanistic investigations reveal the key importance of aggregation changes in Selectfluor® and H−TEDA(BF4)2 to fill gaps of understanding in how radical C(sp3)−H fluorination reactions work. This study exemplifies how an overlooked reaction waste product can be upcycled for a high value-added application.

The increase in the use of electric vehicles (EVs) will ultimately lead to an increase in the number of end-of-life lithium-ion batteries (LIBs) that need to be recycled. A particular challenge concerns how to deal with low value cathodes, such as LiMn2O4 (LMO). To this end, this paper investigates recycling cathode material from an end-of-life Gen 1 Nissan Leaf (2011 model, 40,000 miles) which contains a mixture of spinel (LMO) and a Ni-rich layered oxide (LO). Citric acid was employed to selectively leach LMO into solution while leaving the remaining LO as a solid. The citric acid also acts as a delamination agent to remove the remaining LO from the Al current collector. The LMO was then recovered from solution and upcycled to form new cathode materials. Ni-doping of the solution allowed the synthesis of the high voltage cathode LiMn1.5Ni0.5O4 (LMNO) which is attracting commercial interest. Disordered rocksalt compounds Li4Mn2O5 and Li2MnO2.25F were also synthesised and gave a high specific discharge capacities of 293 and 279 mAh g-1 respectively. This work demonstrates a method to upcycle end-of-life cathode material into next generation cathode materials.

Structural conjugation greatly affects the optical and electronic properties of COF photocatalyst. Herein, we show that 2D hydrazone COFs with either π-extended biphenyl (BPh-COF) or acetylene (AC-COF) framework demonstrated distinct charge transfer and photocatalytic performances. The two COFs show good crystallinity and decent porosity as their frameworks are enforced by intra-/interlayer hydrogen-bonding. However, computational and experimental data reveal that AC-COF managed broader visible-light absorption, narrower optical bandgaps and performs efficient photoinduced charge separation and transfer in comparison with BPh-COF, meaning that ethynyl skeleton with enhanced planarity better improves the π-conjugation of whole structure. As a result, AC-COF exhibited an ideal bandgap for rapid oxidative coupling of amines under visible-light irradiation. Furthermore, taking advantage on its better charge transfer properties, AC-COF demonstrated considerable enhanced product conversion and notable functional tolerance for metallaphotocatalytic C–O cross-coupling of wide range of both aryl bromides and chlorides with alcohols. More importantly, beside recoverable, AC-COF showcased the previously inaccessible etherification of dihaloarene. This report shows facile approach for manipulating structure–activity relationship and paves the development of COF photocatalyst for solar-to-chemical energy conversion.
