Alexander Bogdanov's Red Star, published in 1908, was an attempt to reenergize the dejected revolutionaries whose efforts had been crushed during the 1905 Russian Revolution. The protagonist, Leonid, is a Russian revolutionary chosen, in the midst of the revolution, by the Martian expedition to visit their planet and learn about the centuries-old advanced form of communism there. Since the triumph of communism in Russia was the cause to which Leonid had decided to devote his life, he agrees to visit Mars so that he can absorb their ideas and principles.

Published: February 2021

Daerah Pantai Pasir Palik, Bengkulu Utara merupakan salah satu daerah dengan tingkat abrasi yang tinggi. Salah satu faktor pemicu cepatnya laju abrasi adalah morfologi dasar laut yang mempengaruhi tinggi gelombang yang sampai ke pantai. Tujuan penelitian ini untuk mengetahui bentuk morfologi dasar laut di daerah Pantai Pasar Palik dengan survey batimetri dan membandingkannya dengan data batimetri dari Badan Informasi Geospasial (BIG) resolusi 25 m, Earth Topography 1-Arc Minute Gird (ETOPO1) dengan resolusi 1850 m dan General Bathymetric Chart of the Ocean (GEBCO) resolusi 450 m dan 900 m. Pengambilan data dilakukan dengan pemeruman menggunakan Single Beam Echosounder danGlobal Positioning System (GPS). Koreksi pasang surut dilakukan dengan bantuan perangkat lunakwxtide4.7. Hasil penelitiaan menunjukkan pada pengukuran Echosounderkedalaman maksimum mencapai10 m, sedangkan data BIG maksimum 8 m, GEBCO 450 m mencapai 55 m, GEBCO 900 m mencapai 32 m sedangkan ETOPO1 hanya 2,67 m. Kemiringan morfologi dasar laut dikategorikan landai dengan nilai kemiringan 0,32˚. Morfologi bawah laut di daerah pantai dapat dipengaruhi oleh faktor hidrografi dan oseanografi, maka penelitian lanjutan sangat diperlukan untuk melihat dinamika perubahan morfologi dasar laut. The Palik Coast area, North Bengkulu, is one of the area with high level of abrasion. One of the factors triggering the rapid rate of abrasion is the seabed morphology which affects the height wave energy near the coast. The purpose of this study was to determine the seabed morphology based on slope of seabed in Pasar Palik coast area with bathymetry survey, and also to compare the result with other bathymetry data; the BIG with resolution of 25 m, ETOPO1 with resolution of 1850 m and GEBCO resolution of 450 m and 900 m. The research was carried out by measuring bathymetry using Single Beam Echosounder and GPS. Tidal correction was conducted by using wxtide4.7 software.

Published: February 2021

Ascorbyl-6-palmitate (AP) was a lipid-soluble synthetic ester of ascorbic acid that has been used as a preservation agent for foods and as an antioxidant in cosmetics and related products. This study aims to investigate the effect of shearing management and ascorbyl palmitate administration on physiological and hematological profiles in under heat load Padjadjaran sheep. The physiological profile involves respiration rate (RR), Pulse rate (PR), and rectal temperature (RT). Twenty rams Padjadjaran 1 – 1,5 year-old, weighing between 25 to 47.5 kg used from sheep breeding station Purwakarta, West Java - Indonesia. There are two treatments level in this research, (1). Shearing divide into two groups, unshearing (c0) and shearing (c1); (2). AP administration also divides two groups, not given (a0) and given 400 mg each head daily (a1). The whole treatments were a0c0, a0c1, a1c0 and a1c1. Heat exposure application was exposed to sunlight when the sheep exposed, the animal tethered by rope at the neck region. The sheep exposed to the sun when the ambient temperature at least 34oC, 180 minutes each day, three days a week. The result showed that AP administration and shearing have interaction effects on RR, PR and RT. The level of glucose and total protein is affected by interaction effect of AP administration and shearing, while cholesterol affected to shearing. The conclusion, supplementing AP and shearing application could reduce the negative impact of heat stress on physiological and blood metabolite profiles of Padjadjaran sheep. Although the wool of local breed has not economic value, the shearing is regularly needed.

Thinking ethics differently (challenges and opportunities for engineers education)
Authors: Pasca Carmen Mariana , Riman Chadi Fouad
Published: February 2021

Ethics has many definitions, each depending on its domain. In the ancient times, ethics was based on the principles of good action and the search for the common good.  Generally, Ethics is understood as a system of moral principles which affect our ways of living. Ethics are related with what is good for society and individuals and is described as moral philosophy. Ethics only makes sense if we put them in the context of human action understood as responsible, creative and communicative. Applied Ethics and Codes of conducts have appeared in the contemporary period. One of the key issues in the engineering education ethics program is the problem of margins/limits of autonomy that will enable future engineers to act ethically in accordance with universal ethical principles and the existing codes of ethics. Computer ethics adds the intellectual property rights, and also the use of personal data. The paper shows a general review of ethics, its history, its evolution, with an emphasis on engineering education. It also mentions the big data issue in ethics.

Published: February 2021

This study aims to analyze the economic feasibility of hiring new technicians in order to meet the existing demand for technical assistance. For this, a sensitivity analysis was performed and the data was collected in a qualitative and quantitative way. After that interviews were carried out and quality tools were applied, such as: brainstorms, cause and effect diagram and also financial and cost data was collected during the process. Thus, it was possible to identify that the main causes of the problem is the unavailability of technicians. Thus, an initial solution was developed to create financial configurations to assess which decision would be most plausible. Finally, the best performance scenario was to hire only one new technician, as it maximizes the company's net profit and the representative percentage of that profit from the generated revenue; it was also considered to what extent the solution could be applied. This research is important not only for the studied company, but also for others that have similar problems and need instructions to create a direction for a solution.
The UK’s Post-Brexit Trade Policy
Authors:   Primakov National Research Institute of World Economy and International Relations, Russian Academy of Sciences, Portanskiy Alexey
Published: February 2021

The article focuses on the positions of Britain and the EU in the process of a post-Brexit trade agreement. The key disagreements between the parties that almost led to the failure of the deal are described. The final agreement reached on December 24, 2020 ‒ a week before the end of the transition period ‒ is analyzed. The agreement formally allowed London and Brussels to declare the achievement of their main goals. At the same time, the agreement did not solve all the problems between the parties. The efforts of the United Kingdom to conclude trade agreements with the United States and some other partners after Brexit are also considered. London's initial reliance on President Donald Trump's promises to conclude the most favorable agreement after Brexit did not materialize, and serious disagreements arose between the parties that could not be resolved quickly. The economic benefits of Brexit are not obvious in the near future.
European Union’s Industrial Policy: a Next Version
Authors:   Institute of Europe, Russian Academy of Sciences, Tsirenshchikov Vadim
Published: February 2021

The article is dedicated to the industrial policy of the European Union and its official interpretation. It outlines the existing approaches to the formation of the conceptual structure of this policy, the main stages of its evolution, priorities, tools and measures of implementation, the main target areas of financing. The existing conventionalism of the EU activities designated to regulate the industrial sector in the capacity of an industrial policy is shown, a clarification of the concept of this policy is proposed. Such regulation today goes far beyond the sectoral framework and, extending to almost all spheres of the economy, acquires a cross-cutting general economic nature. Particular attention is paid to the latest version of industrial policy, which convincingly indicates an increase in the innovative trend in the area of economic activity referred to as industrial policy. There is a radical expansion of the range of its innovative priorities to ensure the formation of a regional innovation economy for sustainable development. As a result, this policy serves as an organic component of innovation policy. At the same time, the rapid updating of the proclaimed versions of the EU industrial policy definitely shows that it has become a tool for the implementation of urgent adjustments to the economic course in accordance with the objective requirements of modern development.
USSR and Germany: on the Way to June 22, 1941
Authors:   Institute of Europe, Russian Academy of Sciences, Schweitzer Vladimir
Published: February 2021

The article deals with the Soviet-German relations in the period of 1939‒1941. It is shoun that after signing of the Munich agreements in September, 1938, Germany generally defined its strategy of pressure on countries that fit into the Hitler’s concept of "Push to the East". Its victims in 1935 were Czechoslovakia and Poland. After the German occupation of Czechoslovakia, Great Britain and France sought to review the "policy of appeasement" of Hitler and were ready to join the USSR in the search for ways to prevent Hitler's expansion. However, the inconsistency and contradictoriness of this "change of milestones" strengthened the position of the Soviet leadership in favour of reaching agreements with Germany. The summer of 1939 was the apotheosis of fruitless negotiations between the "Troika" (the USSR, Great Britain and France), which objectively prompted Moscow to accept the German proposal for fundamentally new bilateral agreements (the Pact of August 23, 1939). Subsequent events up to June 22, 1941 showed the unreliability of agreements with Nazism, facilitated the fleeting victory of Germany over Poland and France, and the actual isolation of Great Britain. Hitler's attack on the Soviet Union did not remove from the Soviet leadership the historical guilt of being unprepared for war with fascism, for the colossal human and territorial losses of the first stage of the Great Patriotic War
Sociálna a postpenitenciárna starostlivosť o ťažko vychovateľnú mládež na Slovensku v 70. rokoch 20. storočia – ako sa riešil „neexistujúci“ problém?
Authors: Šuhajdová Ivana
Published: February 2021

The Socialist society had a clear idea on an education and on a direction of the development of children as the future generation. Children were expected to become physically and morally developed citizens according to the requirements of the then government in power. Even though the governing political representation promoted the claim that social problems were a capitalist advancement and had no place in the socialist society, the opposite was true. The idea of the perfect society without social problems was only a political bubble, bursting of which, besides other areas, was very quickly manifested also in lives of some children and youth in a form of a delinquency. The contribution aims to describe the activities of social workers and social curators of the national committees in terms of a social and post-penitentiary care for difficult youngsters in Slovakia in the 1970s.
„Stručná historie Literatury české“. K osudu nevydané učebnice rajhradského benediktina Bedy Dudíka k dějinám české literatury z roku 1847
Authors: Mahel Richard
Published: February 2021

In the years 1841–1854 the Benedictine Beda Dudík (1815–1890) worked as a teacher at the Episcopal Institute of Philosophy in Brno and then at the Higher Grammar School in Brno. As a teacher and a supporter of a development of the Czech national movement in Moravia he strove for the introduction of teaching of the Czech language and literature in the Moravian church education. He succeeded in his efforts and the Court study commission and the Episcopal ordinariate in Brno permitted teaching of the Czech language within the school curriculum of the Institute of Philosophy. For the successful completion of the teaching, Dudik compiled a textbook for his students about history of the Czech language and book writing and he intended to publish it in print at “Matice česká” in Prague. The textbook was approved successfully in a censorship procedure; however, it was not finally published in print due to disagreements with the authors of the compiled works. Nevertheless, it was significant for the development of national efforts in Moravia and it, first and foremost, revealed the young Beda Dudík as a great supporter of the then minority Czech national movement in Moravia, which changed later when he left his pedagogical experience in favour of his better-known historiographical, official and diplomatic practice.

Authors connected to this periodical took a quite strong stance on this issue and criticized the introduced reform in many ways and on many levels. The aim of this study is to create an overview of the most relevant and frequent opinions presented by the authors during the years 1928–1935 and to try to find common threads and themes of their positions. This includes providing a historical, pedagogical and religious context of the newly formed Czechoslovak Republic.
Diagnostic Role and Therapeutic Perspectives of Endoscopic Ultrasound for Pancreatic Neuroendocrine Tumor
Authors: Choi Jun-Ho
Published: February 2021

Pancreatic neuroendocrine tumors (PNETs) are rare tumors with malignant potential, but their incidence has appreciably increased over the last few decades. Diagnosis of PNETs is often difficult with conventional imaging methods. Cross-sectional imaging localizes less than 10% of PNETs less than 1 cm in diameter. Endoscopic ultrasound (EUS) has been shown to be superior to other imaging techniques in the preoperative localization and diagnosis of PNETs. The finding of a hyperenhanced lesion on contrastenhanced EUS was highly predictive of PNETs different from adenocarcinoma. Preoperative assessment of tumor differentiation and Ki-67 is an important prognostic factor for grading. Thus, EUS-guided fine needle biopsy may play a key role in the work-up of nonfunctioning PNETs, and attempts to measure Ki-67 on cytologic and histologic samples have been made. According to the European Neuroendocrine Tumor Society guidelines, there is no clear evidence of a survival benefit of surgery for nonfunctioning G1 PNETs <2 cm in diameter. The benefits of curative surgery must be weighed against operative morbidity and mortality. Although surgical resection remains the mainstay for PNETs, EUS-guided ablation offers a relatively safe and effective treatment option in patients deemed unfit for, or who do not want to undergo, surgery. EUS-guided ablation provides an attractive therapeutic nonsurgical option for patients; however, further studies that better elucidate the long-term outcomes with standardization of technique will help define its role in the treatment of PNETs. The role of EUS in the diagnosis and treatment of PNETs is expected to make much progress in the future.

Published: February 2021

Choledochocele is the least common type of choledochal cyst. Choledochocele has a potential for carcinogenesis, but only a handful of cases with concurrent ampullary carcinoma have been reported. We recently experienced a case of choledochocele with tubulovillous adenoma with focal high-grade dysplasia, which was successfully and completely resected en bloc via endoscopic papillectomy. Prior to endoscopic papillectomy, the endoscopic ultrasonography was able to accurately diagnose the ampullary tumor arising in choledochocele. Herein, we would like to report this case and discuss the potential of malignant transformation and the usefulness of endoscopic ultrasonography in choledochocele.

Published: February 2021

We present the case of a 47-year-old Caucasian previously healthy woman with a voluminous thyroid nodule occupying almost the entire anterior neck region. The lesion had progressively increased in size during the previous 3 months and the patient presented intermittent symptoms of dysphagia and odynophagia with a slight change in voice. Fine needle aspiration showed papillary carcinoma. Based on imaging and cytological findings, the patient underwent total thyroidectomy. The surgical sample revealed a totally enlarged thyroid gland (weight: 208 g) with the presence of a poly-lobulated lesion centrally located and involving the isthmus and both lobes. Hobnail features were present in more than 30% of the neoplastic cells in agreement with the criteria for this subtype. Psammoma bodies and focal necrosis were also present. The extra-thyroidal extension included strap muscles and peri-esophageal glands. Immunohistochemistry using VE1 antibody for detecting BRAF-V600E mutation resulted positive. The final diagnosis was papillary thyroid carcinoma (PTC) hobnail variant (HVPTC)-pT4a. The HVPTC is a rare entity and, in most cases, appears like a unifocal lesion with a maximum tumor size of 8 cm reported so far. To our knowledge, this represents the largest tumor ever described (14 cm), showing rapid growth and with multinodular goiter-like aspect.

Learning points:

HVPTC is an aggressive variant of PTC, usually associated with radioactive iodine refractoriness, and a higher mortality rate compared to classic PTC. However, there is a marked individual variability in this association.

HVPTC usually appears as small unifocal lesion but a multinodular goiter presentation may occur.

The present case highlights that despite of the histology, our patient achieved a high ablation success rate after radioactive iodine therapy.

Eight Forms of Abuse: The Validation and Reliability of Two Multidimensional Instruments of Intimate Partner Violence
Authors: Vasiliauskaitė Zuzana , Geffner Robert
Published: February 2021

Many researchers are still relying on older and more rigid instruments focusing mostly on the physical aspect of intimate partner violence (IPV). This way multidimensionality of IPV and complex experiences of IPV survivors’ are overlooked by many researchers, practitioners and decision-makers. Therefore, our study aimed to adopt to Lithuanian two multidimensional scales: the Composite Abuse Scale (CAS) and the Scale of Economic Abuse (SEA). As well as confirm its validity and reliability for the use for determining the experiences of Lithuanian women in intimate partner relationships. Through various channels 311 women, survivors of IPV were recruited. The structure of both measurements was validated using Confirmatory Factor Analysis (CFA) and internal consistency using McDonald’s omega coefficient. Relying on the newest research we confirmed a five-factor structure for the CAS with the five factors being: Severe Combined Abuse, Sexual Abuse, Emotional Abuse, Physical Abuse, and Harassment. We also confirmed the three-factor structure for the SEA, resulting in Economic Control, Economic Exploitation, and Employment Sabotage. The instruments demonstrated high internal consistency. The validated instruments that measure multidimensionality of IPV will allow a more comprehensive data and knowledge collection of women’s experiences in abusive relationships.

The new experimental data of the 12С(15N,14N)13С reaction cross-sections at the energy Еlab(15N) = 81 MeV were measured for the ground and excited states of 14N and 13C nuclei. The experimental data were analyzed within the coupled-reaction-channels method (CRC) using channels-coupling scheme with the 15N + 12С elastic scattering and one- as well as two-step transfers of nucleons and clusters performing CRC-calculations with the Woods - Saxon potentials (WS) for the entrance and exit reaction channels. The WS potential parameters for the 12С + 15N nuclear interaction were taken from the previously studied elastic and inelastic scattering of 15N ions by 12С nuclei at the energy 81 MeV, and the WS potential parameters for the 14N + 13С reaction exit channel were deduced from fitting of the 12С(15N,14N)13C reaction data. The spectroscopic factors (amplitudes) of transferred in the reaction nucleons and clusters, used in the CRC-calculations, were computed within translational invariant shell model of 1p-shell. It was found that transfers of neutrons (n) and deuterons (d) dominate in this reaction. Multi-step transfers of nucleons and clusters give small contributions to the reaction data.

This paper describes the testing of titanium dioxide, chemically modified by arsenate groups, as an adsorbent of 90Sr from the component of aquatic ecosystems of the Chornobyl exclusion zone. It is shown, that the chemical composition of the aquatic environment impacts 90Sr adsorption. The 4As-TiO2 adsorbent reduces the activity of some samples by almost 100 %, which indicates selectivity and high adsorption capacity of the adsorbent in relation to 90Sr. In some experiments, this value reached 100 %, and the activity was reduced to the level of the maximum permissible 90Sr concentration.

This work is dedicated to figuring out robust epoxy/magnetite/boron carbide (EP/Mag/B4C) composite for radiation attenuation at multiple applications related to nuclear installations, as well as restoration mortar for cracking developed in concrete biological shields. The mechanical properties (flexural, compressive, and impact strengths) and the physical properties (water absorption, porosity, and dry bulk density), each, have been performed to label the composite integrity for practical application. In practice, attenuation properties have been performed by using a collimated beam emitted from spontaneous fission 252Cf (100 μg) neutron source and neutron gamma spectrometer with stilbene scintillator. The pulse shape discrimination technique which would come of the zero cross over method was used to measure the fast neutron and gamma-ray spectra. Thermal neutron fluxes have been measured by using the thermal neutron detection system and the BF-3 detector. The attenuation parameters: precisely, macroscopic effective removal cross-sections ΣR (cm-1), macroscopic cross-sections Σ (cm-1), and total attenuation coefficients μ (cm-1) of fast and thermal neutrons and total gamma-rays respectively were evaluated using the attenuation relations. Also, the MCNP5 code and MERCSF-N program have been used to compute the parameters theoretically. When applicable, measured and calculated results were compared, and it tells us a comprehensive agreement.

Authors: Ogle Sarah B. , Dewberry Lindel C. , Jenkins Todd M. , Inge Thomas H. , Kelsey Megan , Bruzoni Matias , Pratt Janey S.A.
Published: February 2021

OBJECTIVES:

In this report, we compare weight loss, comorbidity resolution, nutritional abnormalities, and quality of life between younger and older adolescents after metabolic and bariatric surgery.

METHODS:

From March 2007 to December 2011, 242 adolescents (≤19 years of age) who underwent bariatric surgery at 5 clinical centers in the United States were enrolled in the prospective, multicenter, long-term outcome study Teen–Longitudinal Assessment of Bariatric Surgery. Outcome data from younger (13–15 years; n = 66) and older (16–19 years; n = 162) study participants were compared. Outcomes included percent BMI change, comorbidity outcomes (hypertension, dyslipidemia, and type 2 diabetes mellitus), nutritional abnormalities, and quality of life over 5 years post surgery.

RESULTS:

Baseline characteristics, except for age, between the 2 cohorts were similar. No significant differences in frequency of remission of hypertension (P = .84) or dyslipidemia (P = .74) were observed between age groups. Remission of type 2 diabetes mellitus was high in both groups, although statistically higher in older adolescents (relative risk 0.86; P = .046). Weight loss and quality of life were similar in the 2 age groups. Younger adolescents were less likely to develop elevated transferrin (prevalence ratio 0.52; P = .048) and low vitamin D levels (prevalence ratio 0.8; P = .034).

CONCLUSIONS:

The differences in outcome of metabolic and bariatric surgery between younger and older adolescents were few. These data suggest that younger adolescents with severe obesity should not be denied consideration for surgical therapy on the basis of age alone and that providers should consider adolescents of all ages for surgical therapy for obesity when clinically indicated.

Methods: This study was performed retrospectively on type 2 DM patients who were admitted to Ankara Atatürk Training and Research Hospital. 118 randomly selected patients were divided into 3 groups that were non-diabetic (Group 1), who received OAD therapy (Group 2), and those who received insulin therapy (Group 3). HbA1c, MPV, PDW levels were collected, analyzed and compared with each other. Results: MPV and PDW values were increased in type 2 DM patients compared to the control group (Group 2; p <0.001 and Group 3 p <0.001, respectively). There was no statistically significant difference between MPV and PDW values in patients treated OAD and insulin therapy (p=0.736 ve p=0.360 respectively). A statistically significant positive correlation was found between HbA1c values and MPV (p <0.001) and PDW (p <0.001) values. Conclusions: In our study, no significant difference was found bet-ween MPV and PDW values of patients using insulin and oad. Early initiation of conventional insulin therapy in patients with type 2 diabetes provides good glycemic control. Rational drug use in accordance with the guidelines; gains importance in treatment success. Skipping this factor may reduce the efficiency of other efforts in relation to rational treatment.
The Determination of knowledge level of family physicians for frailty; A Cross-sectional study
Authors: Akturan Selçuk , Tuncel Bilge
Published: February 2021

Introduction: Frailty syndrome, which affects the quality of life negatively in patients of 65 years old and over, can be observed from physical inactivity to immobility, and can affect cognitive disorders. General symptoms of frailty are; slowing walking speed, involuntary weight loss, decreased appetite, decreased body mass index (BMI), decreased muscle strength, feeling insufficient while doing physical activity, weakness, fatigue, impaired cognitive functions, and memory loss. Fragility is reversible, but if it is not noticed earlier it can progress to immobility or death. Comprehensive Geriatric Assessment (CGA) is important in detecting a frail elderly. The aim of the study is to determine the knowledge level of family physicians in Erzincan. Methods: This is a cross-sectional study. It is aimed to reach at least 80% of family physicians (FPs) employed actively in 73 primary care units in Erzincan. The researchers applied questionnaire face-to-face to the participants. Erzincan Clinical Research Ethics Committee approval was received for the study. SPSS 23 statistics program was used for data analysis. Results: The frailty questionnaire was applied to 58 FPs. Only 12.1% of FPs correctly answered the question of which word first comes to mind for ‘frailty’. The 74.1% (n: 43) of participants did not consider themselves sufficient for CGA, and 70.7% (n: 41) of participants wanted training on CGA. The answer for question if they evaluate the patients for frailty in homecare visits was yes in 38.2%. Conclusion: It can be said that the ‘frailty’ knowledge level of FPs should be increased in Erzincan. In light of the data obtained, it may be suggested to organize “frailty” and CGA trainings for family physicians. Frailty and CGA should be included in undergraduate medical education and continuous trainings of FPs.

Published: February 2021

Objective: The aim of this study to evaluate the approaches of pregnant women to gestational diabetes mellitus (GDM) screening test. Methods: 102 women with gestational age is 24-28 week, at the age of 18 and over, who were not diagnosed with Type I or Type II DM before the pregnancy, with a single pregnancy, were included in the study. Socio-demographic characteristics of pregnant women, risk factors for GDM, whether GDM screening test and the reasons why pregnant women did not have screening test were questioned. Weight, body mass index, plasma glucose measurements and OGTT results of pregnant women with and without GDM risk factors were compared. Results: 53 (51.96%) of 102 pregnant women included in the study did not have GDM screening test. As the reason for not having a test; seven (13.2%) of the pregnant women thought that they should be screened with another method without sugar, six (11.3%) did not recommend by their doctor, six (11.3%) read in the media that test was harmful, six (11.3%) thought that test would harm the baby, and six (11.3%) stated that they did not know about the test. Ten (18,9%) did not report any reason. The rate of women in the risk group for GDM was 87.3%. The highest risk factor was the maternal age above 25 years (79.4%). In addition, 27,4% of pregnant women had first-degree relatives with Type II DM, 8,8% had a history of giving birth more than 4 kg in their previous pregnancy and 3.9% of women were diagnosed with GDM in their previous pregnancy. In pregnant women in the risk group for GDM; the mean age, weight, BMI and 50 g OGTT result were significantly higher than the other group. GDM was detected in six of 49 women had OGTT and all were in the risk group. Conclusion: GDM screening test rates of pregnant women are gradually decreasing. This is not due to educational level or socio-demographic characteristics. Pregnant women receive false information, especially through the media, and the importance of the issue cannot be understood adequately. Health personnel have important duties; risk factors that are proven to be associated with GDM should be questioned at first encounter with pregnant women. Screening test should be performed in early pregnancy in risky pregnant, who do not want to have screening tests should be followed up frequently with blood glucose measurements.
A Formal Model of a Partitioned Real-Time Operating System in Promela
Authors: Staroletov Sergey Mikhailovich
Published: February 2021

Real-time partitioned operating systems meet the current avionics standard of reliable software; they are capable of responding to events from devices with an expected speed, as well as sharing processor time and memory between isolated partitions. Model-based Checking is a formal verification technique in which a software model is developed and then it is automatically checked for the compliance with formal requirements. This method allows proving the correct operation of the model on all possible input data, all possible ways of processes switching and interactions. In this article, we describe a formalized model of an open-source partitioned operating system POK. We implement the model in Promela language for SPIN tool with the purposes of formal verification using the Model Checking method. The model is designed to describe the behavior of: partition and process schedulers, system calls through a software interrupt, kernel libraries for working with synchronization primitives and processes awaiting, user code which consists of several processes in different partitions that are synchronized through a semaphore. The described approach can be used to verify the correct synchronization, the proper operation of the scheduler algorithms, and the accurate data access from different partitions by introducing the corresponding requirements in the form of formulas of the linear-time temporal logic.

Published: February 2021

Objective: The aim was to determine the prevalence and types of the allergies present among dental professionals in Costa Rica. Materials and Methods: We performed a cross-sectional study on 664 dentists who completed a self-reported questionnaire. A descriptive cross-sectional study with inferential analysis was carried out. Results: Dentists reported allergies prior to studying dentistry in 39% of cases, 36% reported chronic illnesses, and 61% of the dentists reported first-degree relatives with some type of allergic reaction. Different allergies had  a similar prevalence among the dental professionals (ranging between 19%-26%), all allergic manifestations occurred  within the first 120 minutes after exposure. The average time of exposure to dentistry-related environments was 16 years (95% CI) among all the dentists surveyed. Conclusions: There is a positive correlation between the presence of a chronic illness and the predisposition to develop allergic reactions among dentists. In addition, there is a directly proportional relationship between age, time of exposure to dental environments, and the risk of developing allergic conditions to dental materials. The main adverse reactions reported due to exposure to dental materials, medicines and/or food were gastrointestinal, skin, and respiratory problems.

We extend by 300 m the known upper elevational range of the Marsupial frog, Gastrotheca marsupiata (Dumeril & Bibron, 1841), to 4,660 m a.s.l. This record makes G. marsupiata the highest occurring frog in its genus, which is already characterized by high-elevation distributions. We suggest that this record may represent a case of climate-induced range shifting and discuss this record in the context of our still limited understanding of how amphibian distributions are being affected by climate change.

Published: February 2021

We record for the first time the species Pimpla croceiventris (Cresson, 1868), P. golbachi (Porter, 1970), and P. sumichrasti Cresson, 1874, belonging to the Pimplini tribe (Ichneumonidae, Pimplinae), in northeastern Brazil. These species have been recorded in the south and southeast of Brazil, except for P. croceiventris, which has also been recorded in the north of the country. Regarding the development of larvae and its physiological characteristics, Pimpla Fabricius, 1804 is one of the most well-studied genera within ichneumonids. These new distribution records will contribute to the understanding of physiological tolerances in different habitats as well as discoveries of new parasitoid-host interactions in new environments.
A Cegueira Pandêmica Saramaguiana como Metáfora de Época
Authors: Villas Boas Alex
Published: February 2021

O objetivo deste artigo é oferecer categorias que ajudem a refletir o evento pandemia em seu impacto cultural, que inaugura um tempo de busca de revisão de mentalidade, face às fragilidades que se desvelam na ocasião. Neste sentido, o evento pandêmico pode ser ligo à luz do romance Ensaio sobre a Cegueira de 1995, do escritor português José Saramago, desde uma perspectiva lacaniana sobre o papel do imaginário no desafio cultural de integração da alteridade. Tanto o romance português como o referencial lacaniano de alteridade tem sido objeto de hermenêuticas teológicas que indicam seu potencial de elucidação teórica do momento histórico que se vive no Ocidente, em que a alteridade se apresenta como um desafio dos novos tempos. Neste sentido, o evento pandemia se apresenta também como alteridade radical que desvela a real condição em que se encontra a sociedade e cultura contemporânea.
No princípio era o rap: a construção do mito em 'Sobrevivendo no Inferno', de Racionais Mc's

Published: February 2021

Neste artigo abordaremos alguns aspectos referentes ao mito e ao seu desenvolvimento em Sobrevivendo no inferno, dos Racionais Mc’s. Primeiramente, procuraremos discernir a trajetória do mito no rap brasileiro a partir de três blocos históricos: (1) até os anos 1989, (2) 1990-1999 e (3) de 2000 em diante.  A partir da concepção do rap enquanto literatura oral urbana, tentaremos esclarecer a relação entre do mito e da experiência religiosa com a obra em questão. Em seguida, buscaremos descrever como se dá a construção de uma cosmogonia periférica através da faixa “Gênesis”, e apresentaremos uma proposta de leitura metafórica do mito em alguns trechos da faixa “Capítulo 4 versículo 3”, a fim de encontrar um caminho de acesso ao conteúdo poético do texto.
