Menjaga kesehatan dan kebugaran agar stamina tubuh tetap prima dan sistem imunitas / kekebalan tubuh meningkat.Mencuci tangan dengan benar secara teratur menggunakan air dan sabun atau hand-rub berbasis alkohol. Mencuci tangan sampai bersih selain dapat membunuh virus yang mungkin ada di tangan kita, tindakan ini juga merupakan salah satu tindakan yang mudah dan murah. Sekitar 98% penyebaran penyakit bersumber dari tangan. Karena itu, menjaga kebersihan tangan adalah hal yang sangat penting.Ketika batuk dan bersin, tutup hidung dan mulut Anda dengan tisu atau lengan atas bagian dalam (bukan dengan telapak tangan).Hindari kontak dengan orang lain atau bepergian ke tempat umum.Hindari menyentuh mata, hidung dan mulut (segitiga wajah). Tangan menyentuh banyak hal yang dapat terkontaminasi virus. Jika kita menyentuh mata, hidung dan mulut dengan tangan yang terkontaminasi, maka virus dapat dengan mudah masuk ke tubuh kita.
Penerapan sila kedua pancasila dalam pelayanan pasien BPJS
Authors: Zahra Viola Az
Published: October 2022

BPJS adalah badan hukum yang beroperasi sejak 2014 serta memiliki wewenang untuk memberikan jaminan sosial berbentuk kesehatan dan ketenagakerjaan. Program ini mulai diselenggarakan pada tahun 2014 melalui dasar hukum undang-undang nomor 24 tahun 2011. Salah satu program BPJS adalah asuransi dibidang kesehatan,atau biasa disebut Jaminan Kesehatan Nasional (JKN). Namun, di Indonesia masih menjadi sorotan karena dinilai kurang baik dalam memberikan pelayanan kepada pasien BPJS. Beberapa kasus meyatakan bahwa rasa ketidakmanusiaan dan tidak adil ke pasien itu masih ada. Mengingat sila kedua dalam pancasila yang berbunyi Kemanusiaan yang Adil dan Beradab, sehingga dengan ini diskriminasi dalam layanan kesehatan harus ditiadakan. Peran pancasila dalam hal ini sangat penting untuk meningkatkan pelayanan kepada pasien. Karena dalam menjalankan profesi sebagai tenaga kesehatan, memberikan pelayanan yang terbaik untuk pasien merupakan sebuah kewajiban.

Authors: Devinta Eriza Dzikra
Published: October 2022

Munculnya Covid-19 ke Indonesia menimbulkan banyak dampak yang buruk bagi warga negara Indonesia. Meningkatnya kasus penyebaran virus ini dan meningkatnya kematian warga negara Indonesia membuat pemerintah Indonesia mengeluarkan kebijakan-kebijakan untuk menghentikan penyebaran dan menurunkan tingkat kematian di Indonesia. Kebijakan yang sampai sekarang masih berlaku adalah penerapan protokol kesehatan Covid-19 yaitu mencuci tangan, memakai masker, menjaga jarak, mengurangi berkerumun, dan menjaga kesehatan/pola hidup sehat. Nilai-nilai pancasila merupakan sumber norma moral bagi penyelenggaraan kenegaraan dan pelaksanaan hukum di Indonesia, terutama dalam masa pandemi Covid-19 yang memasuki kehidupan new normal. Terutama nilai sila kedua Pancasila yaitu mengembangkan sikap saling mencintai sesama manusia, tenggang rasa, tidak semena-mena terhadap sesama manusia, menjunjung tinggi nila-nilai kemanusiaan. Dengan mematuhi protokol kesehatan sesuai anjuran pemerintah, maka setiap individu sudah berusaha menjaga dan melindungi orang lain. Hal itu selaras dengan sila kedua, yakni kemanusiaan yang adil dan beradab.Pengamalan dari Pancasila adalah tantangan terbesar dari Pancasila itu sendiri. Untuk menginternalisasikan Pancasila dalam kehidupan sehari-hari perlu salah satunya untuk selalu disiplin. Pancasila bukan sekedar slogan ataupun pajangan di ruangan-ruang kantor pemerintah namun harus menjadi sikap dan perilaku sehari-hari yang salah satunya adalah disiplin menjaga prokes. Obat dan vaksin paling mujarab untuk melawan corona adalah disiplin menjaga prokes.

Sebelum kita cari tahu penerapan sila kedua, dalam situasi pandemi COVID-19, kita perlu mempelajari dulu makna dari sila kedua panca sila.Kemanusiaan yang adil dan beradab, berarti menandakan bahwa tidak ada perbedaan antar-manusia, lo. Suku A tidak lebih unggul dari suku B. Setiap orang harus menghormati orang lain tanpa melihat latar belakang suku, ras, agama, atau strata ekonomi.Sila kedua, juga bermakna bahwa di depan aturan atau hukum, orang yang memiliki strata tinggi atau orang yang datang dari strata sosial yang rendah adalah sama. Tidak ada yang lebih diuntungkan atau pun dirugikan.Hak Asasi Manusia (HAM) selalu ditegakkan, ya.Setiap orang bisa memperoleh akses yang sama ke fasilitas kesehatan, pendidikan, dan sebagainya. Oleh karena itu, Adjarian, simbol rantai dalam sila kedua dapat kita artikan, jika kemanusiaan dijunjung secara adil dan beradab, bangsa kita akan menjadi bangsa yang lebih kuat.
Identifying Inefficient Strategies in Automation-Aided Signal Detection
Authors: Tikhomirov Lana , Bartlett Megan Louise , Duncan-Reid Jackson , McCarley Jason S.
Published: October 2022

Automated diagnostic aids can assist human operators in signal detection tasks, providing alarms, warnings, or diagnoses. Operators often use decision aids poorly, though, falling short of best-possible performance levels. Previous research has suggested that operators interact with binary signal detection aids using a sluggish contingent cutoff (CC) strategy (Robinson & Sorkin, 1985), shifting their response criterion in the direction stipulated by the aid’s diagnosis each trial but making adjustments that are smaller than optimal. The current study tested this model by examining the efficiency of automation-aided signal detection under different levels of task dificulty. In a pair of experiments, participants performed a numeric decision-making task requiring them to make signal or noise judgments on the basis of probabilistic readings. The standard deviation of the readings differed between groups of participants, producing two levels of task difficulty. Data were fit with the CC model and two alternative accounts of automation- aided strategy: a discrete deference (DD) model, which assumed participants defer to the aid on a subset of trials, and a mixture model, which assumed that participants choose randomly between the CC and DD strategies every trial. Model fits favored the mixture model. Results indicate multiple forms of inefficiency in operators’ strategies for using signal detection aids.

REPRESENTACIONES SOBRE LA DIDÁCTICA DE LA ENSEÑANZA DE LAS CIENCIAS DEL PROFESORADO PARTICIPANTE DE UN PROGRAMA DE POSTGRADO EN EDUCACIÓN
Authors: Gebera Osbaldo Washington Turpo
Published: October 2022

Las representaciones de los docentes sobre la didáctica de la enseñanza de las ciencias constituyen un constructo devenido de una estructura y dinámica representacional, en torno a lo que piensan y pretenden desarrollar en su ejercicio pedagógico. En esa comprensión, el proceso metodológico asumido facilito el abordaje de las configuraciones estructurales, desde la evocación y jerarquización de términos inductores (ciencia y didáctica) del objeto representado. La dinámica representacional se determinó a partir de las favorables valoraciones docentes sobre los propósitos, condiciones, modelización, perspectivas y actitudes hacia la enseñanza de las ciencias. Los resultados evidenciaron que la estructura representacional expresa conocimientos y prácticas en torno a la enseñanza de la ciencia escolar, que responden a una “acción técnica instrumental”, de conducción del acto didáctico en razón a procesos vinculados al entorno, la indagación y promoción de la ciencia. En tanto que la dinámica representacional, “moviliza” un decurso que signa a su uso visualizaciones, simulaciones, modelaciones y otros dispositivos facilitadores de la enseñanza. Vistos así, discontinuamente, evidencian estancos representacionales, por lo que una reconfiguración representacional permite una representación íntegra del “objeto”, una significación más acorde con lo configurado y movilizado por los docentes en el acto didáctico. Tales representaciones constituyen un conocimiento representado, con un sentido funcional e interpretativo del devenir del proceso de la enseñanza de la ciencia escolar, reflejando procesos que discurren más allá del aula, y que involucra contenidos y experiencias de la cotidianidad.

Authors: Oke Cathy , Walsh Brenna , Assarkhaniki Zahra , Jance Ben , Deacon Andy , Lundberg Kajsa
Published: October 2022

We present city specific climate action policy recommendations for urban practitioners, government officers, city leaders, and research decision-makers, from the recently released City Research and Innovation Agenda (CRIA). Building on the Global Research Action Agenda for Cities Climate Change Science 2018, updated in 2021—key outputs from the first Cities and Climate Change Science Conference in Edmonton 2018 and the follow up Innovate4Cities 2021 Conference (online)—the CRIA presents the priority city research and policy gaps identified at these two major conferences. With a focus on the nexus of cities, climate change science, and policy innovation, the CRIA is for policy and decision-makers looking to make significant progress on city focused climate action strategies and plans, by focusing their attention on the city-relevant evidence and outcome-oriented partnerships needed across academia, government, business, and civil society. Here, we provide a summary of the CRIA, that presents priorities under four key questions that cities and their partners in research and innovation ask as they develop and implement climate plans: How do we build the evidence base for climate action? How and for whom should we prioritize? What should we do? and How do we finance and scale climate action? We include arguments for why consolidated understanding of data, technology, and knowledge gaps across a city climate action journey is important to accelerate implementation of cities’ climate commitments, as is the need for key partnerships to support cities in meeting climate goals.
Accountability is Imperative to Keeping the Vision of 1.5°C Alive
Authors: Waheed Zainab
Published: October 2022

This commentary by a youth leader from Pakistan discusses how the Global South has disproportionately received the worst impacts of climate change and how, if not stemmed, the effects of climate change will lead to destruction that will render the earth uninhabitable. As warned by climate scientists, global emissions must be drastically reduced to ensure the earth does not heat up beyond 1.5°C. Discrepancies between the abilities of the Global North and Global South to combat and cope with the climate crisis need to be accounted for when international bodies decide on the best strategies to halt the catastrophic impacts of the climate breakdown. The commentary also discusses the historical roots of climate change in colonialism, and voices the youth’s demand for climate justice and climate action.

Authors: Žitnik Slavko , Kern Pipan Karmen , Jesenko Miha , Lavbič Dejan
Published: October 2022

Advancements in technology and software engineering strive to efficiently build robust technologies and deliver them as fast as possible. It has been shown that both could be achieved by reusing existing implementations, libraries, components, and even frameworks. In the field of public administration, which needs to follow and implement national and EU regulations, it is essential to not only have compatible semantic data structures and processes but also to enable cross-sector and cross-border integrations. In this paper, we present the Digital Europe for All project, more specifically, a use case of a reusable prototype - A web component based on semantic data representation. We show that the component can be easily integrated into an arbitrary Web site and supports arbitrary evidence types, represented using the project's ontologies. Reusing such components enables faster creation of interoperable digital public services and opens new opportunities, better mobility, faster processes, and reduced implementation costs.

Information Processing Ability and its Implications for Teaching and Learning
Authors: FOURİE Mariette , SCHLEBUSCH Gawie
Published: October 2022

The aim of this paper is to explore how the brain processes information, and which factors affect the information processing ability of learners in the classroom. From the hierarchical linear modelling (HLM) analysis, it is evident that the independent variables age, home language, language of learning and teaching (LOLT), and average class size affect the information processing ability of learners in the classroom. The process by which the brain acquires, use, and think about knowledge is known as cognition. Cognition are those intellectual or perceptual processes occurring within us that the typical individual would describe as thinking, rational processing, or the mind. Through learning, an individual’s cognition develops long-term changes in mental representations or associations because of environmental learning and experiences. A quantitative design was followed to gather data from Grade 11 learners by means of a questionnaire. The results revealed that information processing ability of learners as a dependent variable was significantly influenced by the following independent variables: age, home language, language of learning and teaching, and average class size. Recommendations to teachers on how to facilitate efficient information processing are made, which could result in meaningful learning and understanding by the learners. It is hoped by the researchers that, employing these tactics, will render valid results that are consistent with the need to enhance learners’ depth and breadth of processing information, and thereby become sophisticated and complex producers of knowledge.

Authors: Gruntov Aleksandr Vladimirovich
Published: October 2022

The formation of cadets' legal competencies during their studies at a maritime university is determined by pedagogical conditions, which are developed by teachers in stages, depending on the content of legal disciplines. During the period of study at the university, cadets first get acquainted with the discipline "Jurisprudence" in the first year. The objective of the course is to develop universal and general professional competencies in the field of legal regulation among cadets, which determine the content of the norms of Russian and international law, taking into account conditions, resources and restrictions. The degree of quality of maritime specialist training depends on the level of professional competence development, which includes legal competencies in the field of Russian and international law. However, the course of the discipline "Jurisprudence" includes general rules of law and does not determine the specifics of the training of cadets in maritime law. Thus, the author proposes in the study the pedagogical conditions for the formation of legal competencies in the study of the discipline "Jurisprudence" and an assessment of their effectiveness. The purpose of the study is to develop criteria and indicators for assessing the levels of formation of legal competencies of cadets in the first year. The object of research is the process of developing diagnostics of pedagogical conditions for the formation of legal competencies. The subject of the study is the assessment of the levels of formation of legal competencies of cadets. The author proposes a system for diagnosing legal competencies, which collectively form a part of the professional competence of a maritime university graduate.

Authors:   PlasmaScience", Rakhadilov B.K. ,   LLP, Ust-Kamenogorsk, Kazakhstan
Published: October 2022

The article presents the results of a comparative study of the effect of bulk and surface hardening on the structure and properties of 20Cr2Ni4A steel. Surface hardening was carried out by the electrolytic plasma method. Bulk quenching was carried out by heating to a temperature of 870 °C, followed by cooling in water and oil. The structural-phase states of20Cr2Ni4A steel samples were studied by metallographic and X-ray structural analysis. Tribological tests of the samples were carried out according to the ball-disk scheme, and the microhardness of the samples was also determined. It has been determined that after volumetric and surface hardening, the hardness and wear resistance of 20Cr2Ni4A steel increase. In this case, the most significant change is observed in samples that have undergone electrolytic plasma hardening. It has been established that high values of hardness and wear resistance of 20Cr2Ni4A steel after electrolytic plasma hardening are associated with the formation of fine-needle martensite
THERMAL POWER PLANT BASED ON A FREE PISTON ENGINE AND A RECIPROCATING GENERATOR
Authors:   Novosibirsk State Technical University, Novosibirsk, Russia, Kaluzhsky D.L.
Published: October 2022

The article discusses an autonomous power supply system based on a Stirling engine and a reciprocating generator. There are analyzed the conditions of its operation, the choice of an external combustion engine and a linear synchronous generator. In the course of solving the problem of supplying autonomous consumers with thermal and electric energy remote from the city infrastructure, a power plant with the capacity of up to 100 VA was developed and manufactured. Its experimental study, as well as the analysis of the patent-informationarray, made it possible to determine the boundaries of using this technical object. The reciprocating generator is driven by a free-piston engine with an external heat supply. For carrying out field experiments, a prototype laboratory model of a free-piston engine with an external heat supply with a linear alternator has been developed. Its main difference from the known types of Stirling engines is the absence of a massive flywheel with a crankshaft and a crank mechanism, which makes it possible to achieve greater tightness and significantly increases the power on output shaft while limiting the outer dimensions. Air is used as the working medium with addition of a small percentage of water, which makes it possible to develop pressure up to 10 MPa. The technical calculation of the generator design has been given, the force required to develop the needed power during the movable element reciprocating movement has been determined. Solutions have been adopted to suppress acoustic noise causing discomfort to consumers. This can in particular be done by placing vibration dampers and designing a generator with a high efficiency. The design of the moving element should minimize mechanical stress on the windings or magnets. The proposed generator can be competitive and can successfully replace traditional low-power sources of electricity with diesel or gasoline engines.
SYNTHESIS OF URANIUM-THORIUM OXIDE POWDERS IN LOW-TEMPERATURE PLASMA OF HIGH FREQUENCY TORCH DISCHARGE
Authors:   National Research Tomsk Polytechnic University, Tomsk, Russia, Novoselov I.Yu.
Published: October 2022

The article discusses the process of plasma chemical synthesis of uranium-thorium oxide powders for a new generation dispersion nuclear fuel. In the course of research, the combustion parameters of the precursors were calculated. Precursors were water-organic nitrate solutions based on uranyl nitrate and thorium nitrate (fissile components), as well as magnesium nitrate (matrix material). The organic component of the solutions was acetone due to the sufficiently high calorific value and good mutual solubility. In the course of thermodynamic calculations, the optimal modes of processing of the water-organic nitrate solutions in low-temperature plasma were determined. These modes ensured the synthesis of oxide powders of the necessary stoichiometry without impurities of unoxidized carbon (soot). Experiments to obtain the samples of powders were carried out with the model solutions in which uranyl and thorium nitrates were replaced by neodymium and cerium ones, which are in the same group of the periodic table. The synthesis was carried out with the use of a plasma chemicalunit based on a high frequency torch plasmatron. The synthesized powders were subjected to a number of analyzes including electron microscopy, particle size analysis, X-ray phase analysis and BET analysis. The results showed that the powders can be classified as nanosized.

RESEARCH ON THE STRUCTURE OF THE MATERIAL BASED ON NANO-AND MICRO-SIZED CUBIC BN SYNTHESIZED FROM MECHANICALLY ACTIVATED GRAPHITE-LIKE BN WITH THE ADDITION OF ALUMINUMUNDER HPHT CONDITIONS
Authors:   Joint Institute of Mechanical Engineering of NAS of Belarus, Minsk, Belarus, Senyut V.T.
Published: October 2022

In the article the structure and phase composition of the material based on nano-and micro-sized cubic boron nitride (cBN) obtained under high pressure and high temperature conditions from mechanically activated graphite-like boron nitride (hBN) in the presence of aluminum (Al), which plays the role of an initiator for the phase transformation hBN → cBN, are investigated. It has been shown that the use of mechanical activation contributes to the formation of cBN nuclei in hBN, which makes it possible to increase the dispersion of the final product. The technological parameters of the cBN synthesis and the amount of Alhave a significant effect on the structure of the material as well as the content of the cubic BN phase in it. The increase in the pressure for the hBN (MA) -10% Al system from 2.5 to 5.5 GPa and the temperature from 1550 °C to 1750 °C contributes to the increase of the content of the cBN phase from 10-15% to 90%. In this case, the size of cBN grains synthesized at pressures of 2.5 and 5.5 GPa is in the range of 200-500 nm and 40-120 nm, respectively. The increase in the amount of Al, temperature and duration for the cBN synthesis leads to the formation of large cBN grains with a size of about 10-50 μm.

The limited information on the manifestation of the parameters of the molecular component of friction -the shear strength of the adhesive bond τ0and the piezoelectric coefficient βof the molecular component for each specific study predetermines the use of purposeful determination of parameters by modeling shear on small-sized samples in order to increase the objectivity and accuracy of the result assessment. The article poses the task of conducting definitive tribotechnical tests of the high-entropy alloy to assess its adaptability to loading and lubrication conditions during contact with steel, cast iron and to establish the nature of the manifestation of the parameters of adhesion properties by modeling shear on small samples. It was found that under conditions of drop lubrication, the surfaces of the samples of the studied materials appear to be compatible and are satisfactorily run-in. In this case, the parameters of high-speed and force loading determine the manifestation of boundary lubrication. The time reaching the steady-state friction mode is practically the same for all systems, and is observed after 7.5 minutes. The obtained graphic patterns and parameters of their mathematical approximation made it possible to determine the nature of the change in the adhesive properties of a high-entropy alloy with a change in shear rates.
EVERAL NOTES ON THE LATTICE THERMALCONDUCTIVITY OF FRACTAL-SHAPED NANOPARTICLES
Authors:   Pleiades Publ., Ltd., Moscow, Russia, Shishulin A.V.
Published: October 2022

Using the additive technologies in the production of nanoparticle-fabricated three-dimensional materials has become one of the most promising ways of obtaining effective and low-cost thermoelectric energy converters. Nanostructuring provides a route to modifying selectively the transport properties which determine the materials thermoelectric efficiency. In this paper, we have shown one more effect which consists in a significant dependence of the contribution of lattice vibrations to the thermal conductivity coefficient of a nanoparticle (its reducing is required in practice) on its morphology for nanoparticles of a pure substance. The particle morphology has been specified by the values of its effective diameter, fractal dimension and surface roughness.Using nanoparticles of pure bismuth at low temperatures as an example, we have demonstrated a notable decrease in the lattice thermal conductivity in “complicating” the particle morphology. In the final section, we have presented methods of calculating characteristics of nanoparticle ensembles, the methodology of measuring the fractal dimension experimentally also being discussed.

Authors:   E.A.Buketov Karaganda University, Karaganda, Kazakhstan, Agelmenev M.E.
Published: October 2022

Experiments on computer simulation of the behavior of polar nematic phenylpropargyl ethers of parachlorophyllens on the surface of graphene nanoribbon made it possible to reveal a number of regularities. The dynamics of moleculesis studied when the dimensions of graphene change under the action of an electric field and temperature. As a research method, the method of molecular dynamics was used in the approximation of a liquid state of aggregation. The simulation was carried out in the atomistic approach. It was shown that the graphene nanoribbon and electric filed defines the self-assembly of the nematic liquid crystals molecules in the biaxial state. These states appear at the variation of the graphene nanoribbon ratio of width to length. It was found that in the clearing area the ordering of the parachlorophyllens starts to grow when the value of the ratio of width to length is 3: 1.
AGNETRON SPUTTERING OF PROTECTIVE COATINGS ON PARTS OF SURFACES OF PRODUCTS AND TOOLS USING MULTIELEMENT TARGETS MANUFACTURED USING A NEW TECHNOLOGY
Authors:   Research Institute of Arms and Military Equipment of the Military Research Center of the National Defense University named after the First President of the Republic of Kazakhstan –Elbasy, Nur-Sultan, Kazakhstan, Berdibekov A.T.
Published: October 2022

Recently, the use of magnetron sputtering for the deposition of protective coatings has been intensively developed. The great prospect of using this method is due to the possibility ofapplying high-entropy coatings, which are used to protect surfaces that are simultaneously exposed to elevated temperatures, aggressive media and various types of wear. However, the use of the method of creating high-entropy coatings greatly hinders the absence in many cases of the required alloys, which have not only a certain qualitative elemental composition, but also a quantitative one. We managed to solve this problem by creating multi-element targets, with the help of which it becomes possible to create not only almost any elemental composition, but also to regulate the quantitative composition of elements. In this paper, we have proposed a method for manufacturing new types of targets for magnetron sputtering, with a detailed description of the technological chain of their manufacture. The novelty lies in the possibility of applying multi-element coatings when using one target. This is due to the fact that the number of different elements in the target can be measured in tens. The paper also presents the obtained positive result of using a target, which included five different metals, during magnetron sputtering.

In today’s security camera systems, artificial intelligence-based computer vision has started to be used instead of human vision. In this study, it is aimed to see and detect images of guns and knives that may be in social and public spaces with computer vision. As a method and model in the study, image processing technology and YOLO algorithms, which are generally known to have very successful results in the literature, were used. Among the YOLO algorithms, YOLOv4, YOLOv5, YOLOR and YOLOX models were used. 5078 images were used as a data set in the study, and 3000 of these images consist of images of weapons and 2078 of knife images. In order to ensure reliability for the experimental study to be obtained from the images, attention has been paid to the fact that the selectivity of the images is difficult. Comparative experimental studies of YOLO algorithms have been carried out and their results have been published. The most successful result in detecting weapons and knives in the images was obtained in the YOLOR model with a map@0,5 value of 97.6%.

Las normas sociales impactan en las creencias y conductas de las personas. Por lo tanto, una norma social que establezca y valide la igualdad entre hombres y mujeres podría propiciar actitudes más igualitarias. Dada la importancia de las normas en las interacciones sociales, el objetivo de este trabajo fue analizar el efecto de las normas igualitarias del colegio y de los pares en las actitudes hacia la desigualdad de género de los y las adolescentes. En concreto, estudiamos si las normas influyen en los niveles de sexismo hostil y benévolo, y en la justificación de la violencia machista. A través de un estudio correlacional con una muestra de estudiantes escolares (N=547), encontramos que cuando la norma de los pares no apoya los estereotipos de género ”es decir, es una norma igualitaria” esta predice niveles de sexismo más bajos y una menor justificación de la violencia machista. La norma del colegio no resultó ser determinante. Estos resultados muestran que las normas sociales de los pares pueden ser usadas como vehículo de cambio social para generar igualdad entre hombres y mujeres en el contexto escolar.

This qualitative study analyzes the perceptions of students recipients of free tuition from 11 Chilean universities about their persistence in university. Through a content analysis, three dimensions of the phenomenon were identified. First, students' free tuition facilitates their persistence in economic, academic and mental health terms. Second, difficulties in social integration within the more elitist private universities are expressed as a result of socioeconomic and cultural differences with the traditional profile of their student body, associated with a higher socioeconomic background. This situation puts persistence at risk. Third, the discourses express the sense of responsibility assumed byÂ  students beneficiaries of free tuition with respect to their studies and communities. These results allow a better understanding of perceptions from the students recipients of the free tuition policy. Because of these perceptions, it is necessary to make some adjustments to the free tuition policy, particularly with regard to its duration and to the possibility of complementing it with maintenance benefits.

These directives contain the indispensable information which is absent in the normative documents created by central and republican powers, and is related to the authorities` intentions in the field of using the grain procurement as an instrument of repressions in Ukraine. The content of directives strengthens the arguments regarding the conceptualization of the formation of power`s plans aimed the Holodomor as a long-term process that had been proceeding in the course of all grain procurement of 1931–1932 not only in 1932. The directives show that the different groups of rural people and local officials had similar behavior strategies to the unrealistic plan of grain procurement in 1931–1932 when the mechanism of Holodomor was being created and in 1932–1933 when the authorities had stepped the Rubicon.

Метою статті є дослідження та визначенні основних тенденцій трансформації економіки АР Крим у 1991–2002 рр. для усвідомлення досвіду реформування економіки та її відбудови в майбутньому. Методологія дослідження ґрунтується на принципах науковості, об’єктивності, системності, історизму, а також включає методи аналізу, синтезу та класифікації. Використання наукової методології забезпечило об’єктивне висвітлення зазначеної проблематики. Наукова новизна роботи полягає у тому, що авторкою на основі статистичних матеріалів розкрито основні тенденції економічної трансформації промисловості АР Крим у пострадянський період у 1991–2002 рр., проаналізовано особливості змін промисловості регіону, розкрито основні проблеми економіки АР Крим у пострадянський період, визначено закономірності та регіональні особливості реформування радянської економіки. Також у статті окреслено фундаментальні соціально-економічні проблеми, які отримала АР Крим у спадщину від СРСР, та шляхи їх усунення. Висновки. В означений період 1991–2002 рр. відбулася еволюція економіки у напрямку лібералізації ринкового господарства. Щодо промисловості, то вона втратила домінанті позиції на користь сільського господарства, торгівлі та курортно-санаторного господарства. Економіка перехідного періоду зіткнулася з низкою нових проблем. Відбувся повний занепад деяких галузей важкої промисловості та повне зникнення окремих із них, наприклад, залізорудної та чорної металургії. Інші галузі виробництва змогли дещо пристосуватися до нових умов, що стосується насамперед підприємств легкої промисловості. До найбільших проблем перехідного періоду відносяться як суто економічні  (брак власної валюти та тонізація), так і позаекономічні – передусім вплив кримінального світу на процеси господарювання.
