Деятельность современных организаций, не зависимо от форм собственности, является высокорискованной. Всего насчитывается до 600 риск факторов. Снижение уровней риском, можно только оценив их. Основой оценки рисков является аналитическая обработка информации, относящейся к сфере деятельности организации. Информация, подлежащая анализу, обычно аккумулируется в базах данных. Доступ к этой информации обычно осуществляется с помощью SQL-запросов, а анализ проводится с помощью прикладного программного обеспечения. Наиболее рациональный вариант - когда сотрудники бизнес-подразделения самостоятельно способны выбрать данные из БД и провести их аналитику. Наиболее удобно, как для выборки информации из баз данных, так и для ее анализа использовать python. Однако в python, являющимся интерпретируемым языком, имеется недостаток с точки зрения обеспечения информационной безопасности - параметры доступа, включающие логин и пароль пользователя, параметры подключения к БД, располагаются в теле программы в открытом виде. Снизить риски нарушения конфиденциальности при доступе к БД позволяет предлагаемый в данной статье вариант.

В статье рассматриваются две часто используемые системы распознавания речи - YandexSpeech.Kit и Google Speech Recognition. Проводится сравнение данных систем при распознавании зашумленной речи при разных отношениях сигнал/шум. На речь уровня 65 дБ накладывается шум, отличающейся от нее по уровню от 20 дБ до -5 дБ с шагом 5 дБ. Отмечается, что предварительное обучение системы распознавания речи не проводится, в эксперименте применяются голоса четырех дикторов общей длительностью записи 100 минут. Экспериментальным путем выявлено, что при низком отношении сигнал/шум системы распознавания речи справляются недостаточно качественно, следовательно, их необходимо доработать для того, чтобы при низком отношении сигнал/шум иметь приемлемый коэффициент распознавания.

Evolution of posts-from rigid to flexible
Authors: Anguswamy Sriganesh
Published: March 2022

Once endodontic treatment is completed, the tooth must be provided with adequate protection. The endodontically treated teeth are considerably more brittle due to structural changes in the tooth structure, which is more prone to fracture if they are not properly crowned. Not every root treated needs a post space. Predominantly when the roof of the pulp chamber is removed, it weakens the tooth thus resulting in the need for strong interior and exterior support like a post system. It is critical that the implications (remaining tooth structure, number of teeth, periodontal support, active caries, and good oral hygiene as well as tooth biomechanics) largely influence the restorative approach. Several alterations of the natural shape of the canal become necessary to accommodate a circular post inside the root. Non-rigid post systems such as glass, quartz, and silicon fiber posts have become hugely popular since their introduction in the 1990s. Requirements include an optimal combination of resilience, stiffness, flexibility, and strength. These posts have modulus similar to dentin and provide a more uniform distribution of stress on the remaining tooth structure. Sometimes an anatomic post becomes necessary where fiber posts are contraindicated. Here, it requires more than one visit. Thus, we need to have a thorough knowledge of what type of post to be used.
What are the potential sources of on-farm contamination of raw milk butter with Escherichia coli?
Authors: Gérard Amaury , Barbosa Naomi , Tanna Sybille Di , Sindic Marianne
Published: March 2022

Description of the subject. According to Regulation (EC) No 2073/2005, Escherichia coli must be enumerated in raw milk butter before sales. Hygiene of batches is acceptable when a maximum of two samples out of five have levels of E. coli between 10 and 100 cfu·g-1. E. coli is still a threat to the safety of raw milk butter. Objectives. This study aimed to identify sources of E. coli in six farms facing recurrent contaminations in butter. Method. Farms were visited three times between March and May 2021. Surface samples and dairy products samples were collected throughout the process for E. coli enumeration and assessment of potential correlations between equipment contamination and hygienic quality of food products. Results. Two major sources of contamination were identified: the lack of efficacy of cleaning and disinfection practices on milk pipelines, junctions and cream separators, and absence of milk cooling in case of time-lapse of more than 2 h between milking and skimming. The use of lactic acid starters could be a helpful way to control E. coli during cream maturation, in association to adequate good manufacturing practices. Conclusions. Levels of E. coli in the considered raw milk butter batches were really high. A new decision tree is proposed that could help manufacturers and food controllers to improve hygienic quality of raw milk butter.

ПОЗИЦИЯ ЦЕННОСТИ УГОЛОВНОГО ПРАВА ПРИ ЗАЩИТЕ ПОРЯДКА ДОСТУПА НА РЫНОК НА ФОНЕ ЭКОНОМИЧЕСКОЙ РЕФОРМЫ
Authors: Ду Ц.
Published: March 2022

Закономерное определение содержания правового интереса преступления незаконной предпринимательской деятельности является основой для принципиального уточнения границ преступления незаконной предпринимательской деятельности. Правовой интерес данного преступления является порядок доступа на рынок, что является текущим общим взглядом, но все ещё существуют многие недостатки, которые должны быть конкретизированы в специальный порядок доступа на рынок. Исходя из наивысшего значения стабильности уголовного права, системного статуса закона о защите и природы судебного права, порядок доступа на рынок защиты уголовного права отличается друг друга. Стоит ли защиты уголовного права правовой интерес данного преступления, в общей сложности есть три критерия: имеет ли она большую и важную ценность, основана ли она на общественных и публичных интересах, может ли она быть восстановлена к личным правовым интересам. На фоне экономических реформ защита особого порядка доступа на рынок уголовное законодательство должно обеспечивать сбалансированность защиты специального порядка доступа на рынок с ценности рыночной свободой и одновременно следовать принципу ропорциональности.

Published: March 2022

Self-assembly is a ubiquitous process spanning from biomolecular aggregates to nanomaterials. Even though the resulting aggregates can be studied through experimental techniques, the dynamic pathways of the process and the molecular details of the final structures are not necessarily easy to resolve. Consequently, rational design of self-assembling aggregates and their properties remains extremely challenging. At the same time, modelling the self-assembly with computational methods is not trivial, because its spatio-temporal scales are usually beyond the limits of all-atom based simulations. The use of coarse-grained (CG) models can alleviate this limitation, but usually suffers from the lack of optimised parameters for the molecular constituents. In this work, we describe the procedure of parametrizing a CG Martini model for a cyanine dye (C8S3) that self-assembles into hollow double-walled nanotubes. We optimised the model based on quantum mechanics calculations and all-atom reference simulations, in combination with available experimental data. Then, we performed random self-assembly simulations and the performance of our model was tested on preformed assemblies. Our simulations provide information on the time-dependent local arrangement of this cyanine dye, when aggregates are being formed. Furthermore, we provide guidelines for designing and optimising parameters for similar self-assembling nanomaterials.

Published: March 2022

Microginins are a large family of cyanobacterial lipopeptide protease inhibitors. A hybrid polyketide synthase (PKS)/non-ribosomoal peptide synthetase (NRPS) biosynthetic gene cluster (BGC) found in several microginin-producing strains – mic – was proposed to encode the production of microginins, based on bioinformatic analysis. Here, we explored a cyanobacte-rium, Microcystis aeruginosa LEGE 91341, which contains a mic BGC, to discover twelve new microginin variants. The new compounds contain uncommon amino acids, namely homophenylalanine (Hphe), homotyrosine (Htyr) or methylproline, as well as a 3-aminodecanoic acid (Ada) residue, which in some variants was chlorinated at its terminal methyl group. We have used Direct Pathway Cloning (DiPaC) to heterologously express the mic BGC from M. aeruginosa LEGE 91341 in E. coli, which led to the production of several microginins. This proved that the mic BGC is, in fact, responsible for the biosynthesis of microginins and paves the way to accessing new variants from (meta)genome data or through pathway engineering.

Authors: Awassa Jazia , Cornu Damien , Ruby Christian , El-Kirat Chatel Sofiane
Published: March 2022

Infections by pathogenic bacteria have been threatening several fields as food industries, agriculture, textile industries and healthcare products. Layered double hydroxides materials (LDHs), also called anionic clays, could be utilized as efficient antibacterial materials due to their several interesting properties as ease of synthesis, tunable chemical composition, biocompatibility and anion exchange capacity. Pristine LDHs as well as LDH-composites including antibacterial molecules and nanoparticles loaded-LDHs were proven to serve as efficient antibacterial agents against various Gram-positive and Gram-negative bacterial strains. The achieved antibacterial effect was explained by the following mechanisms: (1) Direct contact between the materials and bacterial cells driven by electrostatic interactions between positively charged layers and negatively charged cell membranes, (2) Dissolution and gradual release over time of metallic ions or antibacterial molecules, (3) Generation of reactive oxygen species.
Discovery and Characterization of a Terpene Biosynthetic Pathway featuring a Norbornene-forming Diels-Alderase

Published: March 2022

Pericyclases, enzymes that catalyze pericyclic reactions, form an expanding family of enzymes that have biocatalytic utility. Despite the increasing number of pericyclases discovered, the Diels-Alder (DA) cyclization between a cyclopentadiene and an olefinic dienophile to form norbornene, which is among the best-studied cycloadditions in synthetic chemistry, has surprisingly no enzymatic counterpart to date. Here we report the discovery of a pathway featuring a norbornene synthase SdnG for the biosynthesis of sordaricin-the terpene precursor of antifungal natural product sordarin. Full reconstitution of sordaricin biosynthesis revealed a concise oxidative strategy used by Nature to transform an entirely hydrocarbon precursor into the highly functionalized substrate of SdnG for intramolecular Diels-Alder (IMDA) cycloaddition. SdnG generates the norbornene core of sordaricin and accelerates this reaction to suppress host-mediated redox modifications of the activated dienophile. Findings from this work expand the scopes of pericyclase-catalyzed reactions and P450-mediated terpene maturation.
Classifying the toxicity of pesticides to honey bees via support vector machines with random walk graph kernels
Authors: Yang Ping , Henle E. Adrian , Simon Cory M. , Fern Xiaoli
Published: March 2022

Pesticides benefit agriculture by increasing crop yield, quality, and security. However, pesticides may inadvertently harm bees, which are agriculturally and ecologically vital as pollinators. The development of new pesticides---driven by pest resistance to and demands to reduce negative environmental impacts of incumbent pesticides---necessitates assessments of pesticide toxicity to bees. We leverage a data set of 382 molecules labeled from honey bee toxicity experiments to train a classifier that predicts the toxicity of a new pesticide molecule to honey bees. Traditionally, the first step of a molecular machine learning task is to explicitly convert molecules into feature vector representations for input to the classifier. Instead, we (i) adopt the fixed-length random walk graph kernel to express the similarity between any two molecular graphs and (ii) use the kernel trick to train a support vector machine (SVM) to classify the bee toxicity of pesticides represented as molecular graphs. We assess the performance of the graph-kernel-SVM classifier under different walk lengths used to describe the molecular graphs. The optimal classifier, with walk length 5, achieves an (mean over 100 runs) accuracy, precision, and recall of 0.83, 0.71, and 0.72 on a test data set.
Hollow Microneedle Array Fabrication with Rational Design to Prevent Skin Clogging in Transdermal Drug Delivery

Published: March 2022

Microneedle (MN) technology is a promising candidate to replace hypodermic needles for practical use and painless drug delivery. However, the complex top-down fabrication process of functional MN arrays is a bottleneck that hinders their widespread use. Here, we fabricate the tapered hollow MN array with a unique bi-level-tip by combining strain-engineering and capillary self-assembly of carbon nanotube (CNT) microstructures. Strain-engineering facilitated by the offset pattern of the catalyst enables the growth of bent, bi-level CNT microstructures while capillary self-assembly helps constituting the tapered geometry of MNs. The bottom-up fabrication that consists of only two standard photolithography steps and CNT growth to form the scaffold of MNs followed by a polymer (polyimide) reinforcement step to impart mechanical stiffness to MNs provides scalable and less processing steps. The tapered shape of the MN allows 8 times less force to pierce and penetrate the skin compared to the straight MN. The liquid delivery rate of the bi-level-tip MN is measured to be 26% better than the flat tip MN of the same lumen size as its geometry reduces skin clogging effect at the needle tip. In addition, cytotoxicity tests verify that the polyimide reinforced CNT-MNs are biocompatible for future in-vivo applications.
AMAZON PRODUCT REVIEW SENTIMENT ANALYSIS USING MACHINE LEARNING
Authors: Sultana MD.Arsha , P Rakesh , M Sandeep , G Jagadeesh
Published: March 2022

As online marketplaces have been popular during the past decades, online sellers and merchants ask their purchasers to share their opinions about the products they have bought. As a result, millions of reviews are being generated daily which makes it difficult for a potential consumer to make a good decision on whether to buy the product. Analyzing this enormous amount of opinions is also hard and time-consuming for product manufacturers. But in this prospering day of machine learning, going through thousands of reviews would be much easier if a model is used to polarize those reviews and learn from it. This thesis considers the problem of classifying reviews by their overall semantic (positive, negative, or neutral). To conduct the study different supervised machine learning techniques, Support Vector Machine, Naive Bayes, Decision Tree, Random Forest, and Logistic Regression have been attempted on products review dataset from Amazon. Their accuracies have then been compared.

Актуальность. Несмотря на завершение феноменологического этапа развития психиатрии, на сегодняшний день сохранились ощутимые трудности ранней дифференциальной диагностики биполярных и униполярных аффективных расстройств.В сложных дифференциально-диагностических случаях на помощь клиницистам могут прийти объективные методы исследования, среди которых особое место отводится методам функциональной нейровизуализации, основанным на количественной оценке электроэнцефалограмм. Цель:выделить нейрофизиологические критерии, позволяющие разграничить группы больных с биполярными и униполярными аффективными расстройствами, объяснить функциональный смысл найденных закономерностей и соотнести полученные данные с конкретными клиническими переменными. Материалы и методы. Было обследовано 69 пациентов в возрасте 20–55 лет, поступивших на лечение с диагнозом по МКБ-10: расстройства настроения (аффективные расстройства – F30-F39): аффективное расстройство в рамках биполярного аффективного расстройства или в рамках единственного депрессивного эпизода, рекуррентного депрессивного расстройства. У всех пациентов проводились запись и оценка параметров электроэнцефалограммы с вычислением показателей спектральной мощности и когерентности для альфа-, бета- и тета-ритмов. Результаты. Анализ полученных данных показал, что у пациентов с биполярным аффективным расстройством отмечаются статистически значимо более высокие показатели спектральной мощности альфа-ритма в затылочных (р=0,02), правых височных (р=0,028) отведениях и бета-ритма в затылочных локусах (р=0,019), а также межполушарной когерентности бета-ритма во фронтальных отведениях (р=0,044) по сравнению с пациентами с униполярным аффективным расстройством.Обнаружены прямые корреляции между спектральной мощностью бета-ритма и тяжестью депрессивной симптоматики, оцениваемой по шкале Гамильтона (rs=0,394; p=0,013), у пациентов с униполярной депрессией, тогда как у пациентов с БАР обнаружены обратные корреляции (rs=-0,467; p=0,037). Показатели когерентности бета-ритма во фронтальной коре прямо коррелировали с уровнем ангедонии (rs=0,389; p=0,016) у пациентов с униполярной депрессией.

На сегодняшний день одной из актуальных проблем здравоохранения остается пандемия COVID-19, негативно влияющая на здоровье населения во всем мире, в связи с чем необходима координация международных ответных мер с учетом рекомендуемых стратегий выживания и осознанной осведомленности, что обеспечит высокую сопротивляемость неблагоприятным воздействиям пандемии и снижению риска развития психопатологических симптомов. Во всех странах постояннопроводятся исследования воздействия пандемии на психическое здоровье населения. Выявлено, что социальная изоляция, смерть родственников, неизвестность будущего, страх перед болезнью в совокупности являются факторами риска развития психогенных расстройств, а также ухудшения психического состояния при уже существующих расстройствах. Ограничительные меры, связанные с COVID-19, повлияли на модель потребления психоактивных веществ в большинстве стран мира, что может привести к дополнительной угрозе психическому и физическому здоровью населения. Цель: изучить связь влияния стрессовых факторов на формирование психогенных расстройств, таких как тревога, депрессия, посттравматическое стрессовое расстройство, у лиц с синдромом зависимости от психоактивных веществ в период пандемии.Материал. Результаты анкетирования пациентов (n=86) мужского и женского пола в возрасте от 20 до 60 лет, проходивших стационарное лечение в Алтайском краевом наркологическом диспансере (Барнаул) в феврале – сентябре 2021 г. Методы. Миссисипская шкала посттравматического стрессового расстройства, шкалы тревоги и депрессии Бека. Статистические расчеты производились с использованием программ Microsoft Office Excel 2013, EpiInfo7.2. Заключение. Около трети (29,7%) исследуемых испытывали негативное психологическое воздействие пандемии COVID-19. Травматический стресс вызван высокой интенсивностью переживаний из-за угрозы заражения, страхом тяжелых последствий и смертельного исхода, деструктивным воздействием средств массовой информации на общественное сознание без доказательных аргументов. У обследуемых, испытывающих страх летального исхода и убежденных в разрушительном воздействии COVID-19 на физическое и психическое здоровье, чаще встречаются проявления тревоги, депрессии, психогенных расстройств. Так как лица с ПТСР более других склонны к разным дезадаптивным формам поведения, они в первую очередь нуждаются в социальной и медико-психологической поддержке. Наркологические больные относятся к группе высокого риска по развитию психогенных психических расстройств в период пандемии COVID-19, что необходимо учитывать при проведении комплексных лечебно-реабилитационных мероприятий.

Bu çalışma, muhafazakâr influencer takipçilerinin muhafazakârlık ve lüks tüketim konularındaki görüşlerini incelemeyi amaçlamaktadır. Türkiye’de 1980 sonrası dönemde oluşmaya başlayan yeni muhafazakâr orta sınıf, zamanla yaşam biçimine tüketim pratiklerini eklemlemiştir. Yeni muhafazakârlar, tüketimi yaşam biçimine yerleştirirken tüketilen metalar ile İslami değerleri harmanlamaya çalışmaktadır. Çalışmada lüks tüketim ve muhafazakârlık arasındaki ilişki incelenirken nitel araştırmalardan durum incelemesi yapılmış ve veri toplama tekniklerinden derinlemesine mülakat yöntemi tercih edilmiştir. Çalışma kapsamında muhafazakâr influencerları takip eden 12 kadınla görüşme yapılarak bu görüşmeler nitel içerik analizi ile incelenmiştir. Çalışma, Instagram’daki muhafazakâr influencerların lüks tüketimlerinin muhafazakâr kadınlar tarafından normalleştirildiği varsayımına dayanmaktadır. Çalışma sonucunda, İslam’da israf olarak nitelendirilen lüks tüketim ürünlerinin kullanılmasının, zaman içerisinde insanların ekonomik güçlerinin artması ile normalleştiği açığa çıkmıştır. Lüks tüketim ve israf arasındaki ilişki, dinin koyduğu kurallardan ziyade ekonomik güce bağlı olarak açıklanmaktadır. Sosyal medyanın da aracı olduğu tüketim kültürü, israfı günah sayan anlayıştan uzaklaşmalarına ve sürekli alışveriş yapmalarına neden olmaktadır. Böylece, muhafazakâr modayı takip etme sürecinde rol model olarak görülen muhafazakâr influencerlar, zamanla muhafazakârlık algısının değişmesine neden olmaktadır.

ABSTRACT
The Palu City Government plans to reactivate the biogas power plant (PLTBg) project in Kawatuna landfill, which was operated in 2013. Both economic and environmental benefits of the project are important for decision makers. The environmental benefit include the potential reduction of greenhouse gases (GHGs) emissions by the project. The economic benefits are important to estimate as the financial attractiveness of the project, which include the electricity generated and revenue from Certified Emission Reduction (CER). This study aims (1) to estimate the potential GHGs emissions produced by the Kawatuna landfill before PLTBg project, (2) to estimate the potential GHGs emissions reduction due to the project, (3) to calculate the potential CER that can be obtained from the project. This study employs Clean Development mechanism (CDM) AMS-III.G method to estimate the potential GHGs reduction and a simple quantitative analysis to calculate the potential CER of the project. The results show that based on the BAU Scenario in 2021, the estimated baseline GHGs emissions is 16.148,74 t CO2e, the potential GHGs reduction after the project would reach 61,40% of the total GHGs emissions generated and the range of potential CER would be from 28.595.318 IDR to 72.329.334 IDR. From 2021 to 2030, total present value of CER would reach 563.358.389 IDR.

ABSTRAK
Pemerintah Kota Palu berencana menghidupkan kembali proyek pembangkit listrik tenaga biogas (PLTBg) di TPA Kawatuna yang sempat beroperasi pada tahun 2013. Informasi mengenai manfaat yang akan diperoleh dari sudut pandang ekonomi dan lingkungan adalah penting bagi pengambil keputusan. Salah satu manfaat lingkungan yaitu potensi reduksi emisi gas rumah kaca (GRK) oleh proyek PLTBg. Manfaat ekonomi penting untuk diestimasi sebagai daya tarik finansial dari proyek, di antaranya berasal dari nilai potensi energi listrik yang dihasilkan dan penerimaan proyek dari Certified Emission Reduction (CER). Tujuan penelitian ini adalah (1) mengestimasi potensi emisi GRK yang dihasilkan oleh TPA Kawatuna sebelum implementasi proyek pemulihan gas metana, (2) mengestimasi potensi reduksi GRK dari proyek tersebut, (3) menghitung potensi nilai CER yang dapat dihasilkan dari proyek tersebut. Penelitian ini menggunakan metode CDM AMS-III.G untuk mengestimasi potensi reduksi GRK dan menggunakan kuantitatif sederhana untuk   mengestimasi nilai CER proyek. Hasil penelitian menunjukkan melalui Skenario BAU pada tahun 2021, potensi emisi GRK sebelum adanya proyek adalah 16,148,74 t CO2e dan potensi reduksi GRK setelah adanya proyek mencapai 61,40% dari total emisi yang dihasilkan. Potensi penerimaan CER proyek pada tahun 2021 berkisar antara Rp 28.595.318 hingga Rp 72.329.334 dan total present value penerimaan CER pada tahun 2021-2030 mencapai Rp 563.358.389.

Group Membership and Talk Quality in University Book Clubs
Authors: Liebfreund Meghan D. , Wrenn Melissa
Published: March 2022

A critical issue in teacher education is supporting pre-service teachers in their ability to understand and support diverse learners. This study examined the discussions pre-service teachers engaged in during book clubs about multicultural literature to determine how we, as educators, can support discussions that can lead to participants deepening their understandings of the texts and considering multiple perspectives. Specifically, the research question addressed how group composition in the book clubs influenced the quality of talk surrounding multicultural children’s literature. The discussions included 39 participants (students = 26, faculty = 9, staff = 4). The groups that included faculty and staff with students, compared to student-only groups, engaged in higher quality discussions in all areas examined. These include cooperation and collaboration, reason and logic, information and evidence, and perspectives and voice. Implications are discussed for using book clubs as a pedagogical tool to support teacher education around complex issues of diversity and inclusion in our classrooms.

ABSTRACT

Scientific guidelines recommend a minimum of 60 minutes daily moderate-vigorous intensity physical activity for children for disease prevention and healthy living. Innovation in e-technology has pervaded daily life and plays a significant role in educating the next generation. This mode of information has the potential to play a vital role in health education and disease prevention. The purpose of this study is to review children’s mobile or web-based applications (apps) pertaining to physical activity and exercise in terms of the scientific guidelines for cardiovascular disease prevention and as quality educational tools. From the perspective of disease prevention, the electronic applications available commercially to children for physical activity and exercise were examined. A mixed retrospective observational study of children’s physical activity apps for Apple/Android devices, where apps were assessed for presence or absence of scientific guideline indicators, monitoring capability and educational quality indicators. Suitable apps were downloaded from iTunes, Google Play and Microsoft stores and assessed based on scientific guideline variables and British Educational and Communications Technology Agency (BECTA) quality principles. The data was analysed using statistics to evaluate adherence to these quality standards. Based on the findings, recommendations for the future development of new web-based technologies for health were suggested. A quality score was calculated based on indicators from the guidelines on physical activity, monitoring capability and educational criteria (maximum score 20). This quality score showed a mean 12, median 12, and standard deviation of 3.4. In conclusion, the majority of children’s physical activity apps do not adhere to the guidelines and poorly monitor physical activity. They are of reasonably adequate quality as educational tools.
SERBIAN INTELLECTUAL ELITE IN 1941
Authors:   Institut za savremenu istoriju, Bondžić Dragomir
Published: March 2022

The paper gives an overview of the activities of the Serbian intellectual elite during 1941, on the eve of the April War and at the beginning of the occupation. Teachers of the University of Belgrade and members of the Serbian Royal Academy, two key scientific and national institutions, are viewed as the intellectual elite. The attitudes, behavior, and destinies of Serbian intellectuals during 1941 were varied. Among them were individuals who had already played a role in the events at the end of March 1941, as well as those who had taken part in the short-lived April War. Some then found themselves in German captivity, and some in exile. Most of them remained in occupied Belgrade. Some of them supported the German occupational apparatus, while others resisted and took part in the uprising in the summer of 1941. Most of them faced difficult war conditions, propaganda pressure and police repression. In the fall of 1941, dozens of intellectuals were imprisoned in the Banjica camp and released only after the uprising in Serbia was quelled.

THE BIRTH OF THE REPUBLIC OF SERB KRAJINA
Authors:   Institut za savremenu istoriju, Gulić Milan
Published: March 2022

In the complex circumstances of the civil war and the disintegration of the Socialist Federal Republic of Yugoslavia, several new states were created (Slovenia, Croatia, Bosnia-Herzegovina, Serbia, Montenegro, and Macedonia), and during the wars several para-states were formed without being internationally recognized. In the course of 1991, on the territory of the Republic of Croatia, amidst the bloody civil war, the Republic of Serb Krajina was born. Its birth was the result of a transformation of the former Serb autonomous districts into a republic, with the aim of strengthening the position of the Serb people in Croatia on both the international arena and within Yugoslavia. The process of its creation lasted seven whole years, from the proclamation of the Serb Autonomous District of Krajina, through the formation of the Serb District of Slavonia, Baranja, and Western Srem, and the Serb Autonomous District of Western Slavonia, to the unification of the three regions into one, the Republic of Serb Krajina. This paper is based on archival materials, published sources, memoirs, periodicals, and relevant literature.
ON THE WAR AIMS IN THE 1991–1992 YUGOSLAV CONFLICT
Authors:   Institut za savremenu istoriju, Nikolić Kosta
Published: March 2022

This text attempts to identify the war aims in the Yugoslav conflict, distinguishing the real from the proclaimed goals of the sides in this conflict. The focus is on the analysis of the relations between the key protagonists (Slovenia, Serbia, and Croatia) which did not lead to the peaceful resolution of the Yugoslav crisis. The wartime goals of the different sides in Bosnia-Herzegovina are also analyzed, in an attempt to understand the violent separation of their hitherto intertwined identities. In order to realize their goals, the instigators of the warfare were prone to unilateral, mutually antagonistic, and hostile actions, spreading fear and insecurity among the population. The circle of protagonists of the warfare kept widening as the ruling elites were inciting political mobilization in their immediate surroundings, which led to the breakdown of the Yugoslav federal system and furthered the ethnicization of the conflict.
RESISTANCE IN BELGRADE 1941
Authors:   Institut za savremenu istoriju, Ristanović Rade
Published: March 2022

The author of this work strives to sublimate and analyze the forms of resistance of the inhabitants of Belgrade directed against the occupation regime in 1941. The first line of analysis points to the organizational structure and personnel of the Ravna Gora and communist resistance movements in this city. Since July of 1941, the Belgrade Communists had been tasked with carrying out large-scale armed actions in order to raise an open uprising in the city. By analyzing and quantifying sabotage and other actions of this nature, we have tried to determine to what extent the organization of this resistance movement in Belgrade succeeded in implementing the said strategy. Special attention is paid to assassinations, which had become the only form of resistance from the autumn onward. In addition to the organized resistance, this research also focuses on civilian, i.e., unarmed, resistance. In this regard, we have singled out examples of the rescue of Jews and the collection and dissemination of prohibited information. This paper is based on archive sources and relevant literature.
