On Urban Informality: A Pyramid on Slum Upgrading and Placemaking
Authors: Meléndez Fuentes Natalia
Published: July 2019

Las ciudades de hoy día se enfrentan a crecientes tasas de asentamientos informales. A pesar de las cuatro décadas de esfuerzos a escala nacional e internacional para revertir esta preocupante situación, los asentamientos informales se han convertido en el tipo de vivienda más extendido, y la formación de esta clase de barrios no ha hecho más que crecer. La informalidad representa un potencial socavado e inaprovechado, lo que supone un obstáculo tremendo para el progreso humano. El enfoque restrictivo que se tiene de las técnicas de mejora de asentamientos y de sus habitantes solo puede dar lugar a resultados insuficientes e insostenibles. Los pocos programas de mejora de asentamientos informales que son exhaustivos, multidimensionales e integrales dan testimonio de lo mucho que se necesita un cambio de perspectiva. Con este fin, hemos compuesto una pirámide sobre los elementos indispensables en la mejora de asentamientos informales, con el fin de ilustrar nuestra propuesta metodológica para alcanzar soluciones más sostenibles, completas y humanas frente a la informalidad urbana.
A Design Case for Implementing a Collaborative Strategy for Online Teams
Authors: Ergulec Funda , Mannheimer Zydney Janet
Published: July 2019

This paper describes a half semester long curricular and instructional design project focusing on the design and implementation of a collaborative strategy into a fully online graduate class in adult education. The purposeful group assignment and team building strategy, collectively called the collaborative strategy, represents an instructional approach designed to increase the effectiveness of online collaborative learning. In this context, students are strategically assigned to teams based on their study habits, and they participate in several team-building activities designed to maintain the collaborative learning. This paper presents critical design decisions made during the course development, the reasons for those decisions, failures in which the design did not work as planned, and a reflection on the design.

Баланс жизни и работы: семья, свободное время, трудовая деятельность
Authors: Рождественская Елена Юрьевна , Исупова Ольга Генриховна
Published: July 2019

Вниманию читателей предлагается выпуск журнала «Мониторинг общественного мнения», посвященный теме баланса жизни и труда. Термин «Work and Life Balance» («баланс жизни и труда»), сокращенно WLB, постепенно завоевывает русскоязычное исследовательское пространство, отражая важнейшие тренды социальной жизни на ее различных уровнях, –  перспективу удовлетворенности или сбалансированности широкого спектра социальных потребностей и желаний в рамках индивидуального/группового целеполагания. Прежде всего эти потребности касаются двух основополагающих сфер жизни – работы и внерабочего времени. В последней размещены очень разнообразные задачи повседневности от семьи и детей до здоровья и досуга. Но, пожалуй, самым ярким системообразующим признаком этой уже влиятельной концепции является перенос центра тяжести с институциональной регуляции этого баланса на индивидуальные потребности.
Баланс работы и личной жизни и источники стресса научно-педагогических работников российских исследовательских университетов
Authors: Абрамов Роман Николаевич , Груздев Иван Андреевич , Терентьев Евгений Андреевич
Published: July 2019

На основе опроса и полуструктурированных интервью с преподавателями и научными сотрудниками одного из ведущих российских университетов выделяются ключевые источника стресса в профессиональной деятельности академических профессионалов в современной России. К их числу относятся: (1) повышение требований к научной результативности, (2) большой объем административной нагрузки, (3) нарушение баланса труда и личной жизни. Отмечается, что во многом это связано с общемировыми трендами, обусловленными неоменеджериальными реформами науки и высшей школы, а также давлением, вызванным активным участием университетов в гонке международных рейтингов. Также это обусловлено рядом характеристик академического труда в целом, связанным, например, с размыванием границ между работой и досугом. По данным исследования группами риска становятся молодые академические сотрудники, а также те, у кого административная нагрузка занимает значительную долю бюджета рабочего времени. В завершении статьи проблематизируется концепция стресса в сфере академического труда и ставится вопрос о соотношении положительных последствий адаптационного стресса к новым условиям функционирования науки и высшего образования и рискам негативного влияния стресса на академическую систему.
Ловушка гибкой занятости: как нестандартный график работы влияет на баланс между работой и жизнью фрилансеров
Authors: Стребков Денис Олегович , Шевчук Андрей Вячеславович
Published: July 2019

Исследование проблематизирует роль гибких трудовых графиков в жизни самозанятых профессионалов (фрилансеров). Высокий уровень автономии в распоряжении собственным временем не только имеет очевидные преимущества, но и может приводить к самоэксплуатации. Опираясь на данные онлайн-опроса «Перепись фрилансеров» (2019) и RLMS-HSE (2017), мы демонстрируем, что на фоне среднероссийских показателей фрилансеры намного чаще трудятся в нестандартное время: поздними вечерами и ночью, а также в выходные и праздничные дни, когда другие люди отдыхают. Регрессионный анализ показывает, что работа в нестандартное время приводит к ухудшению баланса между работой и жизнью фрилансеров. В наиболее уязвимом положении оказываются женщины; люди, имеющие супруга (партнера); фрилансеры с несовершеннолетними детьми.
Благодарность. В работе использованы результаты проекта «Перепись фрилансеров: мониторинг русскоязычного рынка удаленной работы (2009-2019)», выполненного в рамках Программы фундаментальных исследований НИУ ВШЭ в 2019 году.
Баланс жизни и работы у женщин-полицейских в Вологодской области
Authors: Исупова Ольга Генриховна
Published: July 2019

В статье анализируется сочетание жизни и работы в «мужской» профессии — в полиции — у женщин в Вологодской области. Анализ основан на качественном исследовании, проведенном в 2016—2017 гг. в Вологде, Вытегре, Тотьме и Никольске методами фокус-групп, индивидуальных и групповых интервью. Исследовательской целью было выявление способов поддержания баланса между жизнью и работой женщинами-полицейскими и мужчинами-полицейскими. Задачи исследования состояли в определении особенностей работы женщин и мужчин в полиции, возможного сегрегирования и дискриминации по полу внутри этой профессии, характера сочетания полицейскими рабочих и семейных обязанностей, степени и причин удовлетворенности работой, соотношения профессии с гендерными идеалами самих женщин и мужчин и их окружения, особенностей маскулинных идеалов, характерных для мужчин-полицейских, перспектив карьерного роста женщин и мужчин в полиции. Было выявлено, что мужчины и женщины самостоятельно и по-разному решают проблемы баланса жизни и труда при работе в полиции — первые стремятся проводить как можно больше времени на работе и ищут возможности дополнительного заработка, уделяя, однако, время и домашним делам — прежде всего для сохранения возможности жене также иметь оплачиваемую работу. Женщины поддерживают баланс путем флексибилизации своей общей рабочей и семейной занятости, устраняя временные границы между работой и семейными заботами.  
Благодарность. Статья подготовлена на основании данных, полученных в рамках проекта фонда Хамовники «Участковый уполномоченный полиции в системе взаимоотношений с местным сообществом: анализ ролевых моделей» (2016), а также при поддержке гранта №18-05-0049 от Научного фонда НИУ ВШЭ в 2018—2019 гг. на создание научно-учебной группы по изучению женщин и мужчин на госслужбе в России в рамках государственной поддержки ведущих университетов Российской Федерации «5-100».
Scheduling Transit Voyages of Vessels of Various Ice Classes Across the Northern Sea Route
Authors: Pastusiak Tadeusz
Published: July 2019

Main problem for scheduling vessel transit voyages through the Northern Sea Route is the difficulty in predicting distribution of ice boundaries in regions that cannot be overcome by individual ice classes of vessels. Scheduling of voyage is related to speed that vessels can develop and moment of time when vessels will be able to commence and complete passage safely through areas that are main obstacle and are blocking longest transit passage through the Northern Sea Route. This applies to voyages carried out by vessels navigating on their own and with support of icebreakers. Additional problem is lack of consistency of content of maps of ice cover, which can be used for vessels voyage planning through areas where ice cover occurs. Results of this research on influence of uncertain information related with time window of conditions favorable for navigation of vessels of different ice classes on schedule of theirs voyage on example of summer navigation season 2017 are presented in this work.
The Decisional Nature of Probability and Plausibility Assessments in Juridical Evidence and Proof
Authors: Biedermann Alex , Vuille Joëlle
Published: July 2019

The quantification of uncertainty is a key topic in different theories and accounts of the legal process, ranging from probabilism to explanationism. These accounts invoke probability to various extents. For legal probabilism, probability is the single core concept, whereas other accounts, such as the relative plausibility theory, give it a more limited role, as one consideration among others. At the same time, controversies persist about the nature of probability and the value it may add to the understanding of the broad range of aspects that characterise the legal process. These controversies arise, in part, from the fact that probability itself is the object of confusing debates in many scientific disciplines. In view of these intricacies, this paper argues that the critical analysis and clarification of how to understand and use probability meaningfully remains a topic worthy of investigation across different theoretical perspectives. The first part of this paper critically examines a selection of persisting misconceptions about probability and objections against its use, based on discussions presented in recent evidence law literature. Part II of this paper will blend this discussion with a particular view of probability, interpreted as a personal decision, rarely acknowledged in legal literature. Using a multidisciplinary perspective and a thorough review of historical sources, we illustrate and discuss how the understanding of probability assertion as a decision promotes transparency, honesty, accountability and justifiability. This decisional perspective is further developed and discussed in Part III to show that its logical ingredients underpin key concepts of different theoretical accounts, in particular the assertion of degrees of belief, assessments of relative plausibility and verdicts about ultimate issues at trial. Overall, the paper makes the point that the isolated debates over probability, legal probabilism and reasoning under uncertainty misconceive the primary problem of the legal process, which is decision-making under uncertainty. The proposed decisional perspective clarifies these issues both analytically and descriptively, and resolves divergencies between ostensibly competing concepts such as probability and relative plausibility.
Pointing Error Effects on Mixed RF-FSO Link
Authors: Jain Rashi , Dhiman Sakshi , Kaushik Rahul
Published: July 2019

In this paper, the performance of a mixed dual hop asymmetric radio frequency andfree space optical (RF-FSO) communication link is investigated. A closed form analytical expression for evaluating outage probability of mixed RF-FSO link is obtained. The source to relay link is RF link modelled using Nakagami-m fading. The relay to destination link is an FSO link subjected to atmospheric turbulence, modelled using K-distribution. Decode-and-Forward (DF) relaying protocol is used. Further, the effect of pointing error on the performance of the link is analysed using obtained closed form expression. It has been observed that increase in the pointing error leads to reduction in outage performance of the link.
Classification and mapping of sound sources in local urban streets through AudioSet data and Bayesian optimized Neural Networks
Authors: Verma Deepank , Jana Arnab , Ramamritham Krithi
Published: July 2019

Deep learning (DL) methods have provided several breakthroughs in conventional data analysis techniques, especially with image and audio datasets. Rapid assessment and large-scale quantification of environmental attributes have been possible through such models. This study focuses on the creation of Artificial Neural Networks (ANN) and Recurrent Neural Networks (RNN) based models to classify sound sources from manually collected sound clips in local streets. A subset of an openly available AudioSet data is used to train and evaluate the model against the common sound classes present in the urban streets. The collection of audio data is done at random locations in the selected study area of 0.2 sq. km. The audio clips are further classified according to the extent of anthropogenic (mainly traffic), natural and human-based sounds present in particular locations. Rather than the manual tuning of model hyperparameters, the study utilizes Bayesian Optimization to obtain hyperparameter values of Neural Network models. The optimized models produce an overall accuracy of 89 percent and 60 percent on the evaluation set for three and fifteen-class model respectively. The model detections are mapped in the study area with the help of the Inverse Distance Weighted (IDW) spatial interpolation method.
Effect of mixed anions on the transport properties and performance of an ionic liquid-based electrolyte for lithium-ion batteries
Authors: Chaudoy Victor , Jacquemin Johan , Tran-Van François , Deschamps Michaël , Ghamouss Fouad
Published: July 2019

In this work, the physical, transport and electrochemical properties of various electrolytic solutions containing the 1-propyl-1-methylpyrrolidinium bis[fluorosulfonyl]imide ([C3C1pyr][FSI]) mixed with the lithium bis[(trifluoromethyl)sulfonyl]imide (Li[TFSI]) over a wide range of compositions are reported as a function of temperature at atmospheric pressure. First, the ionicity, lithium transference number, and transport properties (viscosity and conductivity) as well as the volumetric properties (density and molar volume) were determined as a function of lithium salt concentration from 293 to 343 K. Second, the self-diffusion coefficient of each ion in solution was measured by nuclear magnetic resonance (NMR) spectroscopy with pulsed field gradients (PFG). Moreover, an analysis of the collected nuclear Overhauser effect (NOE) data along with ab initio and COSMO-RS calculations was conducted to depict intra and intermolecular neighbouring within the electrolytic mixtures. Based on this analysis, and as expected, all activation energies increase with the Li[TFSI] concentration in solution, and all activation energies were determined from the self-diffusion data for all ions. Interestingly, regardless of the composition in solution, these activation energies were similar, except for those determined for the [FSI]− anion. The activation energy of [FSI]− self-diffusion relatively decreases compared to the other ions as the lithium salt concentration increases. Furthermore, the lithium transference was strongly affected by the lithium salt concentration, reaching an optimal value and an ionicity of approximately 50 % at a molality close to 0.75 mol · kg−1. Finally, these electrolytes were used in lithium-ion batteries (i.e. Li/NMC and LTO/NMC), demonstrating a clear relationship between the electrolyte formulation, its transport parameters and battery performance.
Advancing science in rapidly changing environments: opportunities for the Central and Eastern European Conference on Health and the Environment to connect to other networks
Authors: Suk William A.
Published: July 2019

The Central and Eastern Europe region is faced with longstanding environmental health problems as well as emerging health threats from pollution caused by the region’s recent period of rapid industrialization. As researchers in the region continue to work to address these problems, they could find unique approaches by increasing collaborations between biomedical and non-biomedical scientists and by more closely following the Superfund Research Program model of pursuing basic research, then connecting with stakeholders in the region to share and apply new knowledge. To build upon and leverage research in the region, researchers and stakeholders should work to formalize the bi-annual meeting of the Central and Eastern European Conference on Health and the Environment into a more cohesive organization and make efforts to connect to broader global networks that aim to spread research results and applications around the world. By taking these steps to connect to the broader world of environmental health research, the CEE region stakeholders can reduce pollution-related disease, minimize costs of hazardous waste remediation, and help grow the economy in their region.
Spirituelle Bedürfnisse und Inklusion von Gehörlosen und Menschen mit Hörbehinderung
Authors: Baumann Klaus , Moos Julia
Published: July 2019

Die spirituellen Bedürfnisse von gehörlosen Menschen finden bislang wenig Beachtung in Theologie und empirischer Forschung, obwohl es sowohl eine sogenannte Deaf-Liberation-Theology als auch pastorale Angebote in vielen Diözesen gibt.

In dieser Querschnittsstudie wurden 172 Gehörlose zwischen 18 und 45 Jahren befragt, um ihre besonderen spirituellen Bedürfnisse in Anlehnung an den Spiritual Needs Questionnaire (SpNQ) von Büssing et al. (2018) zu erheben. Für viele Gehörlose sind ihr religiöser Glaube (70 %) und die Teilnahme am Gottesdienst (73,5 %) Ressourcen. Damit sie darin Stärkung und Gemeinschaft erfahren, ist die (gute) Nutzung der Gebärdensprache entscheidend. Hierin erleben über ein Drittel erhebliche Mängel. Existenzielle und generative spirituelle Bedürfnisse sind für die Befragten durchgängig von noch höherer Relevanz (80 % und mehr).

Für eine inklusive Kirche und für eine inklusive Gesellschaft bedarf es des Umdenkens den Gehörlosen gegenüber, um ihnen in ihrer eigenen Kultur der Welterschließung mehr gerecht zu werden und die Gaben, die sie beizutragen sehr bereit sind, anzunehmen.

Published: July 2019

Background: We aim to assess the predictive value of serum neuron-specific enolase (NSE) level in patients with acute ischemic stroke referring to the emergency department. Methods: This systematic review and meta-analysis performed, considering the PRISMA and MOOSE statement guidelines. A computerized literature search of the known medical database conducted by using the relevant keywords. We included studies published before November 2016 in which stroke patients compared with non-stroke controls and also studies evaluating the serum levels of NSE in the study groups. Statistical analysis was pooled in a random effect model analysis using the Comprehensive Meta-Analysis software. Results: We included 12 articles in the qualitative and quantitative analysis, that their quality acceptable based on the Newcastle Ottawa Scale (NOS scale). The pooled effect estimates showed that NSE is significantly higher in ischemic stroke patients in comparison with their controls with a high effect estimate [OR 9.68, 95% CI (3.06 to 30.6)]. The effect estimate remained statistically significant under the fixed and random effects model. Conclusion: Our results show higher levels of NSE in patients with stroke than in the control group, indicating that NSE plays a role in the diagnosis of stroke. In terms of prognosis, there is evidence regarding the direct and indirect relationship; and it founded that serum levels of NSE is higher in larger stroke volume, which needs further research.

Authors: Etemadi Kourosh , Goljanian Tabrizi Ali , Fahimi Mahdieh
Published: July 2019

Background: Tinnitus is a common neurosensory disorder that can bring many problems such as stress and sleep disorders to the patients and affect their quality of life. Unfortunately, its pathophysiology has not been exactly discovered yet, but there have been some studies executed about the possibility of dyslipidemia causing tinnitus. Studying more on this subject and especially on the Iranian population in order to provide us with evidence-based information, can help us find the optimal method to control and treat this disorder. Methods: In this study, 76 patients that have had complaints of tinnitus in the ENT (ears, nose, and throat) clinic of Taleghani hospital, Shahid Beheshti University of Medical Sciences, in the year 2018, were selected. Also, after taking a history about the severity and the onset of their problem, they were examined and also blood samples were taken to check their lipid profiles. Finally, the results of the lab tests, the severity and the onset of their disorder and also their age and sex were statistically analyzed. Results: The study showed that the prevalence of dyslipidemia in patients with tinnitus is not significantly greater than its prevalence in the general population. Furthermore despite the relationship between dyslipidemia and the onset and severity of the tinnitus is not significant, the effect of dyslipidemia on tinnitus shows itself after about one year and a half (P=0.000), it means dyslipidemia does not cause the tinnitus but affects in its duration. It also indicated the most common type of dyslipidemia among the patients that we studied, was Hypercholesterolemia with the prevalence of 23.68%. Conclusion: The Study suggests that despite the Hypercholesterolemia prevalence of 23.68% among these patients, dyslipidemia does not have a significant relationship with the severity of the neurosensory disorder "tinnitus’ overall, but dyslipidemia affects tinnitus after suffering for about one year and a half. Therefore there will not be a need to use blood tests in order to measure the lipid profile factors at the beginning and the first months of the patients’ tinnitus.

Published: July 2019

Background and aims: Patient safety, as one of the main components of the health care quality, implies avoiding any injury and damage to the patient when providing health care services. In other words, patient safety means his or her safety against any adverse and harmful event when receiving health care services. Based on the above-mention explanations, the present study was conducted to determine the patterns of patient safety management. Methods: A systematic review method was used to meet the objectives of the study. In order to access the scientific documentation and evidence related to the subject published during 1998-2018, English keywords including "Patient Safety Model", "Patient Safety", and "Patient Safety of Management" were searched in Medine, PubMed, and Google Scholar databases and Persian versions of these keywords were also looked for in Jihad-e Daneshgahi’s Scientific Information Database (SID) and Iranian Journals database (Magiran). Results: The findings of this study suggested that most of the studies on designing a model for patient safety highlighted important dimensions including guidance and leadership, communication, organizing, information management, control and monitoring, participation and decision-making, as well as planning and coordination. Conclusion: In general, using patterns and frameworks designed for patient safety improves patient safety against uncertain incidents since the human and financial consequences of such incidents impose overwhelming sufferings on patients.

Another Look at the Abrasion Resistance of Concrete
Authors: Park Sungwoo , Pour-Ghaz Mohammad
Published: July 2019

The abrasion resistance of concrete is considered one of its most important properties in applications such as pavements. Despite the existence of significant amount of research data, the correlation between the abrasion resistance and the compressive strength of concrete remains debatable. This is, in part, due to the limitations of the existing abrasion resistance test methods. We introduce a new abrasion resistance test method that addresses the limitations of the existing test methods; using this new test, we investigate the influence of water-to-cement ratio, coarse aggregate type, and coarse aggregate volume fraction on the abrasion resistance of concrete. We also investigate whether a correlation exists between compressive strength and abrasion resistance of concrete.
The Opportunities and Limitations of Using Artificial Neural Networks in Social Science Research
Authors: Pukelis Lukas , Stančiauskas Vilius
Published: July 2019

Artificial Neural Networks (ANNs) are being increasingly used in various disciplines outside computer science, such as bibliometrics, linguistics, and medicine. However, their uptake in the social science community has been relatively slow, because these highly non-linear models are difficult to interpret and cannot be used for hypothesis testing. Despite the existing limitations, this paper argues that the social science community can benefit from using ANNs in a number of ways, especially by outsourcing laborious data coding and pre-processing tasks to machines in the early stages of analysis. Using ANNs would enable small teams of researchers to process larger quantities of data and undertake more ambitious projects. In fact, the complexity of the pre-processing tasks that ANNs are able to perform mean that researchers could obtain rich and complex data typically associated with qualitative research at a large scale, allowing to combine the best from both qualitative and quantitative approaches.
Cardiometabolic Risk and Body Composition in Youth With Down Syndrome
Authors: Magge Sheela N. , Zemel Babette S. , Pipan Mary E. , Gidding Samuel S. , Kelly Andrea
Published: July 2019

BACKGROUND AND OBJECTIVES:

Whether BMI captures adiposity and cardiometabolic risk in Down syndrome (DS), a condition associated with obesity, short stature, and altered body proportions, is not known. We compared cardiometabolic risk measures in youth with DS and typically developing matched controls.

METHODS:

Youth with (n = 150) and without (n = 103) DS of comparable age (10–20 years), sex, race, ethnicity, and BMI percentile underwent whole-body dual-energy X-ray absorptiometry, fasting glucose, insulin, lipids, lipoprotein particles, inflammatory factors, and when BMI percentile ≥85, an oral glucose tolerance test.

RESULTS:

Sixty-four percent of youth with DS had BMI percentile ≥85. Among these, no difference in glucose, insulin, or insulin resistance was detected, but prediabetes was more prevalent with DS (26.4% vs 10.3%; P = .025) after adjustment for demographics, pubertal status, and BMI z score (odds ratio = 3.2; P = .026). Among all participants, those with DS had higher low-density lipoprotein cholesterol (median 107 [interquartile range 89–128] vs 88.5 [79–103] mg/dL; P < .00005), triglycerides (89.5 [73–133] vs 71.5 [56–104] mg/dL; P < .00005), non–high-density lipoprotein cholesterol (non-HDL-C; 128 [104–153] vs 107 [92–123] mg/dL; P < .00005), and triglycerides/HDL-C (2.2 [1.6–3.4] vs 1.7 [1.1–2.5] mg/dL; P = .0003) and lower levels of HDL-C (41 [36.5–47] vs 45 [37–53] mg/dL; P = .012). DS youth had higher high-sensitivity C-reactive protein, interleukin-6, small low-density lipoprotein particles (LDL-P), and total LDL-P, but similar LDL-P size. Youth with DS had less visceral fat (VFAT), fat mass, and lean mass for BMI z score, but greater VFAT at higher fat mass. However, VFAT did not fully explain the increased prevalence of dyslipidemia or prediabetes in youth with DS.

CONCLUSIONS:

Despite similar insulin resistance, youth with DS had greater prevalence of dyslipidemia and prediabetes than typically developing youth, which was not fully explained by VFAT.
Obese and Overweight People Food Profile in Brazzaville, Congo
Authors: Okouango Y.S. Itoua , Mananga Vital , Elenga Michel
Published: July 2019

In Congo Brazzaville, there are two factors that early led the country to turn to importation of meat and agricultural products from developed countries: low performances in both livestock farming and agriculture sectors and the popula-tion growth of people who preferably live in urban centers. The association of those two factors has impacts on people nutritional status. This present study, for the first time, shows the actual situation of overweight and obese people food profile in Congo Brazzaville what shall enable to elaborate a database and take further necessary measures to address the issue. To do so, a food consumption study has been carried out in the nine neighborhoods of Brazzaville, the capital city of the republic of Congo, and concerned 65 households. So, it appears that, of the 26.2% of the investigated people, 58.5% were women. The women were the dominant gender, aged between 31 and 40 (p?0.001). The women who were living alone represented 84.5% and those who were living in couples represented 15.5%. Those investigated people had a low education level: 73.3% of them only attended junior high school. Their households’ monthly income was low too. The households whose sizes ran from 7 to 8 people represented 21.3% and those living with three meals a day at home represented 85.7%. The majority of the investigated people that lived on food dominated by animal proteins represented 92.3%, those living on oilseeds represented 90.8% and simple carbohydrates represented 98.5%. Fruit and vegetables, rich in micronutrients and fibers, were not eaten enough: fruit 3.1% and vegetables 1.5% (p ? 0.001). 86.2% of overweight and obese people had sport activities restrictions. So, people in Brazzaville, according to the above fig-ures, adapt to behavior that leads to obesity. That is why, for such a population, we must initiate a food education and fight bad behavior that leads to obesity.
Simultaneously Testing for Location and Scale Parameters of Two Multivariate Distributions
Authors: Chavan Atul Rajaram , Shirke Digambar Tukaram
Published: July 2019

In this article, we propose nonparametric tests for simultaneously testing equality of location and scale parameters of two multivariate distributions by using nonparametric combination theory. Our approach is to combine the data depth based location and scale tests using combining function to construct a new data depth based test for testing both location and scale parameters. Based on this approach, we have proposed several tests. Fisher's permutation principle is used to obtain p-values of the proposed tests. Performance of proposed tests has been evaluated in terms of empirical power for symmetric and skewed multivariate distributions and compared to the existing test based on data depth. The proposed tests are also applied to a real-life data set for illustrative purpose.

Published: July 2019

Introducción. La satisfacción del usuario es considerada un componente importante en la calidad de la prestación de los servicios hospitalarios. El modelo SERVQHOS permite evaluar la percepción del usuario en los diferentes servicios.Objetivo. Identificar la percepción del usuario en relación con la calidad del servicio de cirugía ambulatoria en una institución prestadora de servicios de salud en Boyacá, Colombia.Materiales y métodos. Se realizó un estudio de tipo descriptivo y de corte transversal con un enfoque cuantitativo para analizar las dimensiones objetivas y subjetivas de la calidad en la prestación del servicio de cirugía ambulatoria.Resultados. En las variables sociodemográficas se destaca: predominio del sexo femenino, edad promedio de 47.5 años y nivel de escolaridad de bachillerato. Según la evaluación con la escala SERVQHOS, los aspectos mejor valorados por los usuarios de la calidad subjetiva son la amabilidad del personal, el trato personalizado y la confianza, mientras que en la calidad objetiva se destacan la apariencia del personal, la señalización, la tecnología y la apariencia de la infraestructura.Conclusión. La percepción del paciente sobre la calidad de los servicios se ha convertido en un factor determinante para establecer planes de mejora dentro de las actividades administrativas de las instituciones prestadoras de servicios de salud.
Virus oncolíticos: un arma contra el cáncer
Authors: Guerrero-Fonseca Carlos Arturo , López-Baquero Miguel Andrés , Bedoya-Rodríguez Angie Andrea
Published: July 2019

Introducción. Los virus oncolíticos son virus atenuados, mutados o que por naturaleza se dirigen y matan específicamente células tumorales, sin afectar a las células normales. La administración intratumoral del virus ofrece la oportunidad de tratar el tumor primario pero no focos metastásicos, los cuales pueden ser alcanzados mediante la administración intravenosa. Sin embargo, su eficiencia puede disminuir por la presencia de una respuesta inmunológica preexistente en los sujetos tratados.Objetivo. Exponer las técnicas utilizadas para envolver y transportar los virus con el fin de eludir el sistema inmunológico antes de que el virus llegue al tumor.Materiales y métodos. Se realizó una búsqueda narrativa de la literatura original y de revisión en las bases de datos PubMed, JSTOR y EBSCO sobre métodos o técnicas utilizadas para el tratamiento del cáncer mediante el uso de virus oncolíticos.Resultados. La formación de nanocomplejos entre los virus oncolíticos y biopolímeros —ya sea mediante la unión química o mediante la unión a través de interacciones electrostáticas o el uso de micropartículas, células transportadoras, liposomas, ultrasonido o terapias combinadas– es eficaz para evitar la respuesta inmunológica del huésped contra el virus.Conclusión. Para evitar la respuesta inmunológica del huésped contra los virus oncolíticos se han desarrollo diversos métodos que permiten la liberación controlada y especifica de los mismos. Sin embargo, debido a la diversidad de los virus, se debe tener en cuenta que la eficacia de los métodos de protección y transporte depende de las características bioquímicas tanto del biomaterial como del virus.

Published: July 2019

Introduction: The combination of online learning environments and classroom education is known as blended learning.Objective: To design, implement and evaluate the blended learning method for teaching radiology to medical students.Materials and methods: Five online modules were designed as part of the Introduction to diagnostic imaging course for medical students. The blended learning method was implemented during the classes given in the terms 2016-II and 2017-I. Academic performance was measured using standardized tests, while the effect of the intervention was obtained by comparing the sample with a control group from the 2015-II period (traditional method).Results: 204 students were included in the blended learning group and 90 students in the control group (traditional method). The median final exam score among the blended learning group was 16.5 (IQR: 15.5-17.8), and 15.0 (RIQ: 13.5-16.5) (p=0.001) in the control group. On average, gained knowledge among the blended learning group was 5.8 (SD:2.4) points. The association between gained knowledge and number of visits to online modules was statistically significant (p<0.05). The proportion of good performance was close to 100% on the satisfaction survey.Conclusions: The blended learning method increases the grades obtained in the tests performed and also shows higher satisfaction rates compared to the traditional method among medical students.

The susceptibility of the field populations of the house fly Musca domestica L. (Diptera:Muscidae) from a livestock farm of the Tyumen region, Russia, to six insecticides (deltamethrin, cypermethrin, thiamethoxam, permethrin, fipronil, chlorfenapyr) is reported. After a forced contact of adult flies of susceptible strains and first generation of field populations with the residues of insecticides at the bottom of glass cups, the median lethal dose of each insecticide was determined by probit analysis. According to the resistance ratio, the susceptibility of the evaluated field population to insecticides increased in the order: cypermethrin < deltamethrin < permethrin ≤ chlorfenapyr < thiamethoxam < fipronil.

Authors: El-Sherif M. W.
Published: July 2019

A new medial patellar ligament splitting technique in cattle and donkeys is presented. It has been successfully applied on thirteen alive animals affected with permanent upward fixation of patella (UFP). The technique is simple, quick and easily applicable. In contrast to other medial patellar desmotomy techniques; the present approach is less invasive, the skin at the surgical site is not incised but punctured, the pericapsular fat and joint capsule are not invaded. Minimal tissue invasiveness limits the infection of surgical site, minimises bleeding and decreases their related postoperative consequences.

Процес вистоювання тістових заготовок складається з багатьох фізико-механічних та біохімічних процесів, що ускладнює управління та отримання оптимальних показників якості на виході готового продукту.Велика кількість регульованих змінних та інформаційних потоків впливає на хід протікання процесу дозрівання тіста. У шафах (камерах вистоювання) підтримується строгий температуро-вологісний режим. Дотримання регламенту технологічного процесу можливе лише за його автоматизації. Питання автоматизації технологічнихпроцесів все більше постає перед сучасними підприємствами. Огляд існуючих розробок показує наявність суттєвих недоліків. На кафедрі АТП і РС розроблено новий підхід до автоматизації одного з процесів виробництва хліба – вистоювання заготовок з тіста. Було розкрито мету технологічного процесу вистоювання тіста та виділено основні технологічні параметри, на які необхідно накласти регламент, для того щоб якість вихідної продукції була відповідною. Враховано можливість реалізації керуючих дій та отримання інформації про фактичні значення технологічних параметрів виходячи з можливостей сучасних технічних засобів автоматизації. Метою роботи єрозробка найбільш близької до процесу вистоювання тіста моделі, яка б описувала його основні властивості з можливістю їх відображення та дослідження. Модель розроблена таким чином, щоб в подальшому її можна було б використати як основу при синтезі моделі системи автоматичного регулювання. Складено структурну схему моделі об’єкта керування. Вагомі вхідні «прямі» та «перехресні» дії математично описані статичними аперіодичними ланками другого порядку. Важливо відмітити, що розроблено модель id-діаграми вологого повітря та доведено її достовірність. Представлена повна математична модель об’єкту керування і зроблено висновок про можливість її використання у подальших розробках.
