Authors: Olufunmilola Olorunsola E. , Christianah Aina A.
Published: May 2020

This study investigated the Influence of Home on the Academic Performance of Students in Afe Babalola University International Secondary School, Ado-Ekiti, Ekiti State. The population of the study comprised all the students in ABUAD International secondary school, Ado Ekiti. A total of 90 (ninety) students selected from the secondary school constituted the sample of the study. The students were selected using stratified and simple random sampling techniques. Two instruments were used to elicit relevant information from the students. The first instrument was a self-designed questionnaire titled “Home Characteristics and Parent Involvement Questionnaire” (HCPQ). The HCPQ has two parts. Face and content validity of the HIPQ was ascertained by experts in educational management, test and measurement. The reliability of the instrument was ensured, and it stood at 0.79. The second instrument was an inventory titled Students’ Academic Performance Inventory (SAPI). The SAPI was used to collect the students’ academic performance in internal examinations. Data collected were analyzed using descriptive and inferential statistics. Research questions were answered with frequency count, percentage scores, mean and standard deviation. The hypotheses were tested with inferential statistics such as Pearson Product Moment Correlation (PPMC) and Multiple Regression analysis. All hypotheses were tested at 0.05 level of significance. The study revealed that the level of students’ academic performance was moderate during the period of investigation. It also revealed that the level of parents’ involvement in the academic progress of the students was moderate. The study concluded by recommending that parents should involve themselves more in the academic progress of their children or wards in order to enhance academic prowess in all ramifications.
Las emociones de la mujer como estrategia publicitaria del campo farmacéutico a comienzos del siglo XX en Chile
Authors: Millones Espinosa Mario , Hernández Maluenda Nicolás
Published: May 2020

El presente artículo tiene como objetivo reflexionar sobre cómo las emociones formaron parte de la expansión del campo farmacéutico a comienzos del siglo xx en Chile. Para introducir el consumo de medicamentos en el hogar, distintas boticas y farmacias publicitaron sus remedios en revistas como Familia. Allí se dieron dos hechos importantes: primero, el uso paulatino de las emociones en los anuncios publicitarios de los fármacos y, segundo, el recurrir a las mujeres de forma constante en esta estrategia. A través de ella en tanto mujer, madre y sus distintas obligaciones morales inscritas en tales roles, creemos que la medicalización de la familia necesitó de cierto argumento emocional para la expansión del campo farmacéutico.

Authors: Hinderaker Katie , Weinmann Amanda
Published: May 2020

Introduction: This study examined whether patients’ perceptions of their primary care providers’ (PCP) listening frequency were associated with emergency department (ED) utilization, including a comparison to patients without PCPs.
Methods: Data were obtained from the 2015 California Health Interview Survey. Respondents were asked if they had a PCP and how often their PCPs listened, resulting in five groups: patients without a PCP (n=4,407), and patients with a PCP who perceived the PCP’s listening frequency to be never (n=254), sometimes (n=1,282), usually (n=3,440), or always (n=11,651). Multiple linear regression was performed to determine if patient-perceived listening frequency of the PCP was associated with the patient’s number of ED visits in the prior year, adjusting for various demographic, social, and health factors.
Results: Compared to patients without a PCP, patients with a PCP had on average 0.15 more ED visits in a year, highest among those whose PCPs were perceived as listening the least: never=0.55 more visits per year (95% CI: 0.09-1.02, P=.02), sometimes=0.26 (0.01-0.51, P=.04), usually=0.03 (-0.17-0.24, P=.73), and always=0.16 (-0.05-0.36, P=.13). Other significant increases in ED visits were associated with public insurance, African-American race, English proficiency, younger age, self-rated fair-to-poor health, asthma, and hypertension.
Conclusions: Patients who perceived their PCP as listening less frequently had more ED visits than patients whose PCPs were perceived as listening more frequently, and compared to patients without a PCP.
An operational approach to financial stability: On the beneficial role of regulatory governance
Authors: Singh Sikarwar Tarika , Sharma Saurav
Published: May 2020

The reviews have shown that regulatory governance increases the economic growth of the country that further improves the financial stability. Weak governance promotes a weak financial sector. It is established that there are several crises took place in ancient times because of failed policy (Greco, Ishizaka, Tasiou, & Torrisi, 2019; Kuc Czarnecka, Lo Piano, & Saltelli, 2020). The purpose of the research is to find out more about how weak governance can damage the economy of nations, and that is how it leads to financial instability. Besides, how good governance leads to economic stability can also be understood. The research problem presented in terms of the objective of the research is to find out the association between financial stability and regulatory governance for the selected nations under study. This is done by taking a sample of fifteen nations of the world. By taking selective indicators for regulatory governance and financial stability and applying the causality test, the association is checked. The results indicate a less significant association between regulatory governance and financial stability for nations under study. The results are relevant in continuously expanding global financial markets wherein emphasis is strong regulations.
Impact of real exchange rate fluctuations on aggregate cocoa and coffee exports in Sierra Leone
Authors: Fofanah Pabai
Published: May 2020

The regression and the vector autoregressive VAR models have been employed in this analysis. I use the autodistributed lag regression model to estimate both the short and the long-run impacts. In the VAR model, orthogonalized impulse response functions are employed to estimate the short-run. The regression result shows that while depreciation of the RER increases aggregate cocoa and coffee exports AGX in the current year, this variable is not significant in determining AGX in Sierra Leone. This is due to the fact that AGX have long gestation periods and until this period is over, suppliers cannot actually raise their output and hence exports. The negative effect of the one period lag of RER variable on AGX can be attributed to the fact that in the long run, depreciation in the nominal exchange rate leads to real exchange rate depreciation. This will lead to increase in cost of imported farming inputs in domestic currency terms. The reduction in imports that follows decreases the output and hence cocoa and coffee exports. However, this variable is not significant in determining AGX in Sierra Leone. An increase in the orthogonalized shock to the first difference of log RER causes a short series of increases in first difference of log AGX followed by a decrease, followed by an increase that dies out after four periods. The null hypothesis that the lag of first difference of log RER does not Granger-cause the lag of first difference of AGX cannot be rejected. The paper concluded that in the short and long-run, the RER should not be taken as policy variable to influence AGX in Sierra Leone.

An adverse maternal in utero and lactation environment can program offspring for increased risk for metabolic disease. The aim of this study was to determine whether N-acetylcysteine (NAC), an anti-inflammatory antioxidant, attenuates programmed susceptibility to obesity and insulin resistance in offspring of mothers on a high-fat diet (HFD) during pregnancy. CD1 female mice were acutely fed a standard breeding chow or HFD. NAC was added to the drinking water (1 g/kg) of the treatment cohorts from embryonic day 0.5 until the end of lactation. NAC treatment normalized HFD-induced maternal weight gain and oxidative stress, improved the maternal lipidome, and prevented maternal leptin resistance. These favorable changes in the in utero environment normalized postnatal growth, decreased white adipose tissue (WAT) and hepatic fat, improved glucose and insulin tolerance and antioxidant capacity, reduced leptin and insulin, and increased adiponectin in HFD offspring. The lifelong metabolic improvements in the offspring were accompanied by reductions in proinflammatory gene expression in liver and WAT and increased thermogenic gene expression in brown adipose tissue. These results, for the first time, provide a mechanistic rationale for how NAC can prevent the onset of metabolic disease in the offspring of mothers who consume a typical Western HFD.
Health Care Costs Associated With Macrovascular, Microvascular, and Metabolic Complications of Type 2 Diabetes Across Time: Estimates From a Population-Based Cohort of More Than 0.8 Million Individuals With Up to 15 Years of Follow-up
Authors: Chen Hsuan-Ying , Kuo Shihchen , Su Pei-Fang , Wu Jin-Shang , Ou Huang-Tz
Published: May 2020

OBJECTIVE

Developing country-specific unit-cost catalogs is a key area for advancing economic research to improve medical and policy decisions. However, little is known about how health care costs vary by type 2 diabetes (T2D) complications across time in Asian countries. We sought to quantify the economic burden of various T2D complications in Taiwan.

RESEARCH DESIGN AND METHODS

A nationwide, population-based, longitudinal study was conducted to analyze 802,429 adults with newly diagnosed T2D identified during 1999–2010 and followed up until death or 31 December 2013. Annual health care costs associated with T2D complications were estimated, with multivariable generalized estimating equation models adjusted for individual characteristics.

RESULTS

The mean annual health care cost was $281 and $298 (2017 U.S. dollars) for a male and female, respectively, diagnosed with T2D at age <50 years, with diabetes duration of <5 years, and without comorbidities, antidiabetic treatments, and complications. Depression was the costliest comorbidity, increasing costs by 64–82%. Antidiabetic treatments increased costs by 72–126%. For nonfatal complications, costs increased from 36% (retinopathy) to 202% (stroke) in the event year and from 13% (retinopathy or neuropathy) to 49% (heart failure) in subsequent years. Costs for the five leading costly nonfatal subtype complications increased by 201–599% (end-stage renal disease with dialysis), 37–376% (hemorrhagic/ischemic stroke), and 13–279% (upper-/lower-extremity amputation). For fatal complications, costs increased by 1,784–2,001% and 1,285–1,584% for cardiovascular and other-cause deaths, respectively.

CONCLUSIONS

The cost estimates from this study are crucial for parameterizing diabetes economic simulation models to quantify the economic impact of clinical outcomes and determine cost-effective interventions.

Authors: Lithovius Raija , Harjutsalo Valma , Mutter Stefan , Gordin Daniel , Forsblom Carol , Groop Per-Henrik , Group FinnDiane Study
Published: May 2020

Objectives. To estimate the risk of diabetic nephropathy (DN) progression,
incident coronary heart disease (CHD) and stroke, and all-cause mortality associated
with resistant hypertension (RH) in individuals with type 1 diabetes stratified
by stages of DN, renal function and sex.

Research Design and Methods This prospective study included a nationally
representative cohort of individuals with type 1 diabetes from the Finnish Diabetic Nephropathy Study who had purchases of antihypertensive
drugs at (±6 months) baseline visit (1995–2008). Individuals (N=1,103) were
divided into three groups: (a) RH, (b) uncontrolled BP, but no RH and (c) controlled
BP. DN progression, cardiovascular events and deaths were identified from the individuals’ healthcare records and national
registries, until 31 December 2015.

Results At baseline 18.7% of the participants had RH, while 23.4% had
controlled BP. After full adjustments for clinical confounders, RH was
associated with increased risk of DN progression (HR 1.95 [95% CI 1.37, 2.79], p=0.0002), while no differences were observed
in those with no RH (1.05 [0.76, 1.44],
p=0.8), compared with those who had controlled
BP. The risk of incident CHD, incident stroke and all-cause mortality was higher
in individuals with RH compared with those who had controlled BP, but not beyond
albuminuria and reduced kidney function. Notably, in those with normo- and microalbuminuria the risk of stroke remained
higher in the RH compared to controlled BP group (3.49 [81.20, 10.15], p=0.02).

Conclusion Our findings highlight importance to identify and
provide diagnostic and therapeutic counseling to these very high risk
individuals with RH.

Published: May 2020

Цель исследования изучение влияния торакопластики с применением полипропиленовой сетки на интенсивность и продолжительность боли по сравнению с традиционной верхнезадней торакопластикой. Материал и методы. Проанализированы 64 случая хирургического лечения фиброзно-кавернозного туберкулеза. Сравнивали длительность и характер боли, наличие осложнений в послеоперационном периоде и эффективность вмешательства. Результаты. Клиническое обследование пациентов на 1-е, 5-е и 21-е сутки после операции свидетельствует о том, что в группе с использованием полипропиленовой сетки базовое обезболивание было эффективнее, чем в группе сравнения, в которой пациенты в большей степени нуждались в дополнительном назначении опиоидов пролонгированного действия. Отмечено более быстрое снижение показателей боли и достижение высокой степени компрессии в основной группе, что позволило добиться закрытия полости деструкции и устранения бактериовыделения у большего числа больных с меньшей частотой осложнений. Заключение. Проведенное исследование свидетельствует о высоком травматизме торакопластики и необходимости длительного обезболивания. Применение сетчатого имплантата при торакопластике у больных фиброзно-кавернозным туберкулезом легких позволяет уменьшить количество удаляемых ребер.

В данном сообщении описаны 4 случая редкого осложнения аннулопластики трикуспидального клапана (ТК) повреждения правой коронарной артерии. Выполнен обзор литературы с последующим анализом. Изучены и обсуждены синтопия правой коронарной артерии к трикуспидальному кольцу, факторы риска и методы лечения данного осложнения. За период с 2010 по 2018 г. на базе отделения неотложной хирургии приобретенных пороков сердца выполнено 807 процедур аннулопластики при функциональной трикуспидальной недостаточности. Диагностировано 4 случая непрямого повреждения правой коронарной артерии с частотой встречаемости осложнения 0,5. Рассмотренная серия случаев с мировым опытом составляют 19 случаев поражения правой коронарной артерии при аннулопластике трикуспидального клапана с госпитальной летальностью 15,8. У всех пациентов с данным осложнением в описанной серии случаев была выполнена шовная пластика ТК по De Vega, имелась аннулодилатация, правый тип кровоснабжения миокарда, повреждение артерии локализовалось в дистальной трети. В секционном исследовании наиболее опасная зона это заднесептальная комиссура, так как именно в этой зоне расстояние от кольца до артерии минимальное при его расширении. По данным литературы, не выявлено зависимости частоты встречаемости осложнения от типа аннулопластики. В 8 случаях из 19 была проведена интенсивная терапия. Метод выбора лечения осложнения реваскуляризация миокарда. Повреждение правой коронарной артерии при аннулопластике трикуспидального клапана всегда сопровождается кардиогенным шоком и / или электрической нестабильностью миокарда. Наложение более поверхностных швов в опасной зоне и избегание стежков к стенке правого предсердия исключат повреждение артерии. Быстрое распознавание травмы артерии имеет решающее значение. При аннулопластике трикуспидального клапана хирург должен быть насторожен в отношении вероятности развития осложнения.

Неспецифический аортоартериит (НАА) идиопатический гранулематозный артериит крупных сосудов, который затрагивает преимущественно аорту, ее основные ветви. Воспаление и повреждение эндотелия обычно приводят к утолщению стенки, стенозирующим и окклюзионным поражениям. Ранняя диагностика и принципы интегрированного управления привели к повышению выживаемости пациентов. Лечение НАА основано на применении иммунодепрессантов, таких как преднизолон и/ или метотрексат, для снижения или устранения воспалительной активности. Развитие в результате стенозирующего и окклюзионного поражения сосудов ишемических регионарных синдромов, таких как сосудистая мозговая недостаточность, абдоминальная ишемия, вазоренальная гипертензия, ишемия нижних конечностей, коарктационный синдром, является показанием для возможной хирургической коррекции. В случае НАА V типа необходимо рассматривать этапное хирургическое лечение как стратегию выбора для получения оптимальных результатов. В статье представлен успешный случай хирургического лечения вазоренальной (реноваскулярной) артериальной гипертензии при НАА (V типа) в условиях прогрессирующего патологического процесса.

Implementation of Shared Decision-Making in Australia
Authors: Ervin Kaye E , Blackberry Irene , Haines Helen
Published: May 2020

Shared decision-making (SDM) is the process of clinicians and patients participating jointly in making healthcare decisions, having discussed evidence-based treatment options and the potential risks and benefits of each option, taking into consideration the patient’s individual preferences and values. SDM is ubiquitous in Australian healthcare policy. While there is good evidence for utilising SDM, clinicians’ knowledge of SDM, the current uptake, effectiveness and acceptability of SDM in Australia is largely unknown. The challenges perceived by clinicians to implementing SDM in clinical practice and potential moral, legal and ethical dilemmas require further debate and consideration.

Measuring instruments for determining composition of exhaust gases of ship internal combustion engines
Authors: Zhukov Vladimir Anatoljevich , Sherban Sergey Andreevich
Published: May 2020

The article describes the problem of air pollution by engines of sea and river vessels. Compliance with environmental requirements established by state and international regulatory documents is a prerequisite for the safe operation of sea and river vessels. The composition of the exhaust gases of marine diesel engines should be considered the main and most objective criterion for the environmental safety of marine power plants. The requirements for the exhaust gases composition and the procedure for determining regulated indicators are established by various regulatory documents which indicate only the principle the device operation. Most regulatory documents do not take into account the capabilities of modern devices and design features of ship power plants. In the process of analyzing exhaust gases, the composition of toxic substances and solid particles is determined by gas analyzers and smoke meters. The principles of operation of modern instruments are described, their capabilities and metrological characteristics are presented, and the prospects for using such instruments on sea and river vessels are evaluated. The problems that arise during the analysis of exhaust gases on small displacement vessels with wet exhaust gases are considered. There have been proposed the measures which will improve the quality of marine diesel emissions control and contribute to improving the technical operation of the fleet. The necessity of updating the instrumental base for monitoring toxicity and smoking of exhaust gases of marine diesel engines is indicated. The solution to the problem requires an integrated approach, taking into account the operating conditions of ships, capabilities of measuring equipment, design features of ship engines, requirements of regulatory documents and rules of classification societies.
Comparative analysis of thyristor schemes of marine DC motor control
Authors: Golovko Sergey Vladimirovich , D'yachenko Artem Vladislavovich , Romanenko Nickolay Gennadievich
Published: May 2020

The article considers the problem of the DC motors control that are often used in many electric drive systems. Due to the progress of industrial electronics and technology it has become possible to develop more efficient motor control circuits. The conventional speed control methods commit power losses in the system, which can be minimized by using the power electronics strategy. There is considered the thyristor control of DC motors of the ship electric drive. The DC motor control systems are described and simulation models in the MATLAB Simulink program are presented. The thyristor methods for controlling a DC motor speed are listed: single-phase semi-controlled converter (for motors with power up to 15 kW); single-phase drive with a controlled converter (available to operate in two quadrants); three-phase semi-controlled converter; three-phase controlled converter; single-phase reverse converter realized by connecting two single-phase converters (ensuring multi-mode operation); three-phase reverse converter realized as a single-phase converter. The mechanical characteristic of a DC motor was illustrated when the voltage supplied to the armature winding changed. It has been stated that control of the armature voltage is more favorable for speeds below the rated speed; flow control is preferable for speeds above the nominal speed. It has been inferred that speed control by means of power electronics devices provides large energy savings, in contrast to the traditional speed control methods, since the traditional methods experience significant energy losses.
Problem of using electrodes made of shipbuilding steel to protect ship hull from corrosion
Authors: Yastrebov Dmitry Pavlovich , Belov Oleg Aleksandrovich , Shvetsov Vladimir Alekseevich , Tarabanov Bogdan Vladimirovich , Zaitsev Sergey Anatolevich
Published: May 2020

The article discusses the problem of corrosion that causes significant damage to the ship structures and mechanisms, reducing their service life. The experience of using different electrodes to control the electrochemical protection systems of steel hulls of auxiliary vessels is presented. The results of corrosion tests of PM-15 ship hull are presented, which included measurements of the hull potential at a given control point, using an electrical measuring device and two control electrodes. As the first electrode used an electric carbon product for electric machines. A ship hull steel plate was used as the second electrode. The investigated vessel stayed at the pier for a long time. Corrosion tests were carried out in the period within 10.10.2019-16.10.2019. The ship hull potential at the control point was controlled using 50 parallel measurements. Parallel measurements were performed with a specified time interval of 5 sec. between them. A qualified operator has been trained to perform corrosion studies. The accuracy of the measurements was determined on the basis of current regulatory documents. The test results show that the reliability of the control of electrochemical protection systems of the hull primarily depends on the type of electrode used. It has been demonstrated that the metrological characteristics of the results of control measurements depend on the period of using a steel plate. The results of scientific research help to select the right elements of the system of monitoring the effectiveness of electrochemical protection of the ships and ship crews.
Analysis of wave fields of free water surface from moving plate, pair of consecutive posts and discussion of likely components of their wave resistance
Authors: Bimberekov Pavel
Published: May 2020

The paper presents and compares photographs of wave patterns from a moving plate with pointed and full ends, from which, with the exception of a cylindrical insert, there develops a post with a teardrop-shaped cross-section, as in a pair of tandem posts. The plate length equals to the overall size of the specified pair of consecutive posts. The conclusion is made about the possibility of selecting a unified wave resistance component from the total resistance, which can be determined experimentally based on the results of the study of a combination of individual posts and/or other objects of the specified shape. Possible variants of wave resistance components are being discussed. Besides, a variant of modeling the ship's wave resistance by representing two pairs of such wave systems rather than two Kelvin wave systems on a free surface is proposed. Additional fore and aft Kelvin wave systems are proposed to be shifted against the course of motion by half the wavelength. These additional wave systems are intended to describe internal intermediate waves located between the main transverse waves. There have been presented the expressions for wave resistance that contain some proportionality coefficients, possible components of wave resistance from smoothing diverging waves within the smoothing zone of wave structures, starting from the bow extremity and other unaccounted components of wave resistance. The photos proposed were taken in the experimental pool of Siberian State University of Water Transport (Novosibirsk State Academy of Water Transport) in 2006
AN IDEOLOGICAL ALTERNATIVE TO THE TECHNOLOGICAL SINGULARITY

Published: May 2020

Thinking about the future of man and humanity against the background of rapidly develop-ing technologies is full of fears and fears. Many of the key provisions proposed by technol-ogy and the financial and economic orders of the society, fall on the poorly prepared con-sciousness and, due to the transience of events, do not leave time for thoughtful analysis. New concepts or their new meanings are taken for granted and become frightening phan-toms that define the chaos of our ideas about the world. One such phantom is the concept of singularity, which in the social and humanitarian space brings only confusion in the minds.

La representación de intereses de la cúpula del sector agropecuario. La Sociedad Rural Argentina (1996-2008)
Authors: Panero Marcelo Oscar
Published: May 2020

Es objetivo de este artículo abordar la representación de intereses de la cúpula agropecuaria argentina, luego de los cambios ocurridos desde fines del siglo XX. Para ello, se analiza la Sociedad Rural Argentina (SRA) entre 1996 y 2008.

Sobre la base de datos cuantitativos, análisis de material institucional y entrevistas a dirigentes, socios e informantes clave, se constató que SRA exhibió un alto grado de inercia institucional. Ello le permitió permanecer como representante de la fracción más tradicional de la cúpula del agro argentino, a la vez que implicó la pérdida de centralidad representativa que tuvo durante buena parte del siglo XX.

Desde su creación, la Argentina como Estado nación ha dedicado una parte importante de sus recursos culturales a la creación de una identidad social homogénea que permitiera a sus ciudadanos reconocerse como argentinos. Todos aquellos que quedaron fuera del proceso de homogeneización debían ser incluidos de alguna manera. En este trabajo analizaremos la forma en la cual se introdujeron a los pueblos originarios en la historia nacional a partir del estudio de la activación patrimonial de la plaza de la fundación en San Miguel de Tucumán. Nos interesa mostrar el entrecruzamiento de los discursos disciplinares y el patrimonio cultural y su transformación a lo largo del tiempo.

In Quantum ElectroDynamics (QED) the propagator is a function that describes the probability amplitude of a particle going from point A to B. It summarizes the many paths of Feynman’s path integral approach. We propose a reverse propagator (R-propagator) that, prior to the particle’s emission, summarizes every possible path from B to A. Wave function collapse occurs at point A when the particle randomly chooses one and only one of many incident paths to follow backwards with a probability of one, so it inevitably strikes detector B. The propagator and R-propagator both calculate the same probability amplitude. The R-propagator has an advantage over the propagator because it solves a contradiction inside QED, namely QED says a particle must take EVERY path from A to B. With our model the particle only takes one path. The R-propagator had already taken every path into account. We propose that this tiny, infinitesimal change from propagator to R-propagator would vastly simplify the mathematics of Nature. Many experiments that currently describe the quantum world as weird, change their meaning and no longer say that. The quantum world looks and acts like the classical world of everyday experience.

Com o aumento da ocorrência de eventos extremos no meio urbano, muitos instrumentos estão surgindo a fim de monitorar as metas e ações das cidades pela busca de comunidades mais preparadas e resilientes. A presente pesquisa teve o objetivo de buscar por indicadores multissetoriais criados com a finalidade de auxiliar os gestores locais no enfrentamento dos riscos e ameaças. Para isto, foi realizada uma análise bibliométrica, a fim de buscar e compreender o perfil mundial quanto a temática. Esta análise foi subdividida em cinco etapas: busca por palavras-chave nos cinco principais portais de pesquisa científica (Capes, Google Scholar, Scielo, Scopus e Web of Science); definição do portal com maiores números de publicações; aprofundamento dos artigos deste portal, filtrando e selecionado àqueles que atendam os objetivos da pesquisa; análise dos resultados; e elaboração de redes de colaboração. Como resultado, tem-se a identificação de 75 indicadores multisetoriais desenvolvidos e publicados, onde o Indicador de Resiliência de Base para Comunidades, o Método Multirrisco e o Índice de Gestão de Risco, são os instrumentos mais citados no meio acadêmico. Os principais periódicos escolhidos pelos autores são o Natural Hazards e o International Journal of Disaster Risk Reduction. Além disso, as maiores cooperações internacionais para a criação dos indicadores se concentram nos Estados Unidos, Espanha e Reino Unido. Os 75 indicadores multisetoriais publicados até o momento apresentam perfis e características próprias que podem servir de base para novos instrumentos, adaptando-os para o atendimento das particularidades de cada região.

Intellectual property and artificial intelligence
Authors: Omorov R. O.
Published: May 2020

Issues, arising in the field of intellectual property rights in connection with the development of artificial intelligence systems and their impact on the development of legal relations in the economy and culture of modern society, have been considered. Aspects of mutual policies in the field of intellectual property rights and the development of artificial intelligence systems for the development of innovation and creativity have been examined. Questions of copyright and ownership in the interaction of man, collective and artificial intelligence or artificial intelligence systems have been raised and proposed. Issues related to artificial intelligence as an object of intellectual property have been considered. The position of the author on the legal personality of artificial intelligence to intellectual property objects created by autonomous artificial intelligence systems has been presented, which is expressed in the answers to the questions of the project of the World Intellectual Property Organization to the wide discussion of interested parties, planned for 2020 at the headquarters of the World Intellectual Property Organization in Geneva. The main conceptual principle of the author on the issues of the planned discussion is to grant the right of copyright and ownership of intellectual property objects created by autonomous artificial intelligence to a dressed subject – a person or collective, a developer of artificial intelligence with fixation of the latter as a sub-subject or instrument of the subject. Traditional categories of intellectual property rights also have been considered, such as patentability and the inventive level of property in connection with the possible generation of these objects by artificial intelligence. Issues related to data, its generation, fabrications and legal relations regarding data have been considered. Harmonization of international intellectual property rights policies to alleviate the technological gap between countries in the context of artificial intelligence development has been examined.

Published: May 2020

Fragment based drug design represents a promising drug discovery paradigm complimentary to the traditional HTS based lead generation strategy. How to link fragment structures to increase compound affinity is remaining a challenge task in this paradigm. Hereby a novel deep generative model (SyntaLinker) for linking fragments is developed with the potential for applying in the fragment-based lead generation scenario. The state-of-the-art transformer architecture was employed to learn the linker grammar and generate novel linker. Our results show that, given starting fragments and user customized linker constraints, our SyntaLinker model can design abundant drug-like molecules fulfilling these constraints and its performance was superior to other reference models. Moreover, several examples were showcased that SyntaLinkercan be useful tools for carrying out drug design tasks such as fragment linking, lead optimization and scaffold hopping.
Data-driven analysis of the number of Lennard-Jones types needed in a force field

We optimized force fields with smaller and larger sets of chemically motivated Lennard-Jones types against the experimental properties of organic liquids. Surprisingly, we obtained results as good as or better than those from much more complex typing schemes from exceedingly simple sets of LJ types; e.g. a model with only two types of hydrogen and only one type apiece for carbon, nitrogen and oxygen.The results justify sharply limiting the number of parameters to be optimized in future force field development work, thus reducing the risks of overfitting and the difficulties of reaching a global optimum in the multidimensional parameter space. They thus increase our chances of arriving at well-optimized force fields that will improve predictive accuracy, with applications in biomolecular modeling and computer-aided drug design. The results also prove the feasibility and value of a rigorous, data-driven approach to advancing the science of force field development.

The construction of enantioenriched azabicyclo[3.3.1]nonan-6-one heterocycles via an enantioselective desymmetrization of allene-linked cyclohexanones, enabled through a dual catalytic system, that provides synchronous activation of the cyclohexanone with a chiral prolinamide and the allene with a copper(I) co-catalyst to deliver the stereodefined bicyclic core, is described. Successful application to oxygen analogues was also achieved, thereby providing a new enantioselective synthetic entry to architecturally complex bicyclic ethereal frameworks. The mechanistic pathway and the origin of enantio- and diastereoselectivities has been uncovered using density functional theory (DFT) calculations.

Solvation of the stable nitroxide radicals 2,2,6,6-Tetramethylpiperidine-1-oxyl (TEMPO) and 4-Oxo-TEMPO (TEMPONE) in water and THF is studied. With electron paramagnetic resonance (EPR) spectroscopy at X- and Q-band as well as spectral simulations, the existence of pure water shells enclosing TEMPO in aqueous solution that lead to significantly reduced local polarity at the nitroxide is shown. These aqueous lower polarity solvation shells (ALPSS) offer TEMPO a local polarity that is similar to that in organic solvents like THF. Furthermore, using double electron-electron resonance (DEER) spectroscopy, local enrichment and inhomogenous distribution without collisions of dissolved TEMPO in water is found that can be correlated with potentially attractive interactions mediated through ALPSS. However, no local enrichment of TEMPO is found in organic solvents such as THF. These results are substantiated by MD and metadynamics simulations and physical methods like DLS and MS.

Aim. Identify in patients with arterial hypertension (AH) the peculiarities of the effect of various classes of antihypertensive drugs on the daily variability of sinus rhythm (HRV). Material and methods. We examined 29 patients with grade 1-2 degree essential AH aged 32 to 60 years (16 men and 13 women) using bifunctional monitoring of ECG and blood pressure before and after treatment with bisoprolol, amlodipine, lisinopril and a combination consisting of lisinopril and amlodipine. We evaluated the hypotensive effect of the drugs associated with the distribution of heart rate during the day and the amount of HRV corresponding to different ranges of heart rate. Results. In cases where the antihypertensive effect (AE) of bisoprolol was expressed, the initial HRV values in the heart rate ranges close to 75 beats/min were significantly greater than in the absence of effect. After treatment, in the presence of AE of bisoprolol, a significant decrease in HRV parameters was observed in these heart rate ranges. AE of amlodipine was associated with an initially high heart rate concentration in the ranges close to 75 beats/min. The efficacy of lisinopril and the combination of lisinopril with amlodipine was associated with an initially high heart rate concentration in the range 69-83 beats/min and its decrease during the treatment. Conclusion. With a random set of patients and a random choice of drugs for the treatment of AH, the presence and absence of an antihypertensive effect was accompanied by statistically significant differences in the initial values and in the dynamics of HRV parameters.
