Authors: Damoiseaux-Volman Birgit A , van der Velde Nathalie , Ruige Sil G , Romijn Johannes A , Abu-Hanna Ameen , Medlock Stephanie
Published: July 2021

BACKGROUND

Clinical decision support systems (CDSSs) form an implementation strategy that can facilitate and support health care professionals in the care of older hospitalized patients.

OBJECTIVE

Our study aims to systematically review the effects of CDSS interventions in older hospitalized patients. As a secondary aim, we aim to summarize the implementation and design factors described in effective and ineffective interventions and identify gaps in the current literature.

METHODS

We conducted a systematic review with a search strategy combining the categories older patients, geriatric topic, hospital, CDSS, and intervention in the databases MEDLINE, Embase, and SCOPUS. We included controlled studies, extracted data of all reported outcomes, and potentially beneficial design and implementation factors. We structured these factors using the Grol and Wensing Implementation of Change model, the GUIDES (Guideline Implementation with Decision Support) checklist, and the two-stream model. The risk of bias of the included studies was assessed using the Cochrane Collaboration’s Effective Practice and Organisation of Care risk of bias approach.

RESULTS

Our systematic review included 18 interventions, of which 13 (72%) were effective in improving care. Among these interventions, 8 (6 effective) focused on medication review, 8 (6 effective) on delirium, 7 (4 effective) on falls, 5 (4 effective) on functional decline, 4 (3 effective) on discharge or aftercare, and 2 (0 effective) on pressure ulcers. In 77% (10/13) effective interventions, the effect was based on process-related outcomes, in 15% (2/13) interventions on both process- and patient-related outcomes, and in 8% (1/13) interventions on patient-related outcomes. The following implementation and design factors were potentially associated with effectiveness: a priori problem or performance analyses (described in 9/13, 69% effective vs 0/5, 0% ineffective interventions), multifaceted interventions (8/13, 62% vs 1/5, 20%), and consideration of the workflow (9/13, 69% vs 1/5, 20%).

CONCLUSIONS

CDSS interventions can improve the hospital care of older patients, mostly on process-related outcomes. We identified 2 implementation factors and 1 design factor that were reported more frequently in articles on effective interventions. More studies with strong designs are needed to measure the effect of CDSS on relevant patient-related outcomes, investigate personalized (data-driven) interventions, and quantify the impact of implementation and design factors on CDSS effectiveness.

Towards More Meaningful Social Media Analysis: Case Study of Utilizing an Age Prediction Algorithm to Identify and Code Reddit Posts about E-cigarettes by Youth vs. Adults (Preprint)
Authors: Navarro Mario , Malterud Andrea , Cahn Zachary , Baum Laura , Bukowski Thomas , Kery Caroline , Chew Robert , Kim Annice
Published: July 2021

BACKGROUND

Previous qualitative studies and data science studies using Reddit for tobacco research are limited by the lack of available demographic information. Social media investigations are often limited to manual qualitative coding or machine learning classification in isolation.

OBJECTIVE

This study combines both machine learning methods and manual qualitative coding to provide contextual age nuance to social media analysis. By being able to predict a Redditor’s age using publicly available data, the most popular posts can be analyzed and qualitatively coded to provide nuanced comparisons on thematic topics by age group.

METHODS

The current study combines these two methods to 1) predict Reddit users’ age into two categories (13-20, 21-54) and 2) qualitatively code Electronic Nicotine Delivery System [ENDS] related Reddit posts within the two age groups. We identified Reddit posts on three topics: Vaping in General, Tobacco 21 Minimum Age Laws, and Flavor Restriction Policies. An age algorithm was used to predict Reddit users’ ages (13-20 or 21-54 year old users). The 25 posts with the highest karma score (number of upvotes minus number of downvotes) for each query and each predicted age group were qualitatively coded.

RESULTS

The top three, two of which were part of the query, out of nine, topics that emerged were “Flavor Restriction Policies”, “Tobacco 21 Policies”, and “Use”. Tobacco 21 and Flavor Restriction Policy posts were prominent coding categories. Opposition to flavor restriction policies was a prominent sub-category for both groups, but more common in the 21-54 group. The 13-20 group was more likely to discuss opposition to minimum age laws as well as access to flavored ENDS products. The 21-54 group more commonly mentioned general vaping use behavior.

CONCLUSIONS

Users predicted to be in the 13-20 age group posted about different ENDS-related topics on Reddit than users predicted to be in the 21-54 age group. Future studies could use these complementary methods with social media data to gain insights from target audiences.
Development of the Socioeconomic Screening, Active Engagement, Follow-up, Education, Discharge Readiness, and Consistency (SAFEDC) Model for Improving Transitions of Care: Participatory Design (Preprint)
Authors: Shin Ji Youn , Okammor Nkiru , Hendee Karly , Pawlikowski Amber , Jenq Grace , Bozaan David
Published: July 2021

BACKGROUND

Transition to home after hospitalization involves the potential risk of adverse patient events, such as knowledge deficits related to self-care, medication errors, and readmissions. Despite broad organizational efforts to provide better care transitions for patients, there are challenges in implementing interventions that effectively improve care transition outcomes, as evidenced by readmission rates. Collaborative efforts that require health care professionals, patients, and caregivers to work together are necessary to identify gaps associated with transitions of care and generate effective transitional care interventions.

OBJECTIVE

This study aims to understand the usefulness of participatory design approaches in identifying the design implications of transition of care interventions in health care settings. Through a series of participatory design workshops, we have brought stakeholders of the health care system together. With a shared understanding of care transition and patient experience, we have provided participants with opportunities to generate possible design implications for care transitions.

METHODS

We selected field observations in clinical settings and participatory design workshops to develop transitional care interventions that serve each hospital’s unique situation and context. Patient journey maps were created and functioned as tools for creating a shared understanding of the discharge process across different stakeholders in the health care environment. The intervention sustainability was also assessed. By applying thematic analysis methods, we analyzed the problem statements and proposed interventions collected from participatory design workshops. The findings showed patterns of major discussion during the workshop.

RESULTS

On the basis of the workshop results, we formalized the transition of care model—the socioeconomic, active engagement, follow-up, education, discharge readiness tool, and consistency (Integrated Michigan Patient-centered Alliance in Care Transitions transition of care model)—which other organizations can apply to improve patient experiences in care transition. This model highlights the most significant themes that should necessarily be considered to improve the transition of care.

CONCLUSIONS

Our study presents the benefits of the participatory design approach in defining the challenges associated with transitions of care related to patient discharge and generating sustainable interventions to improve care transitions.

Serendipity Identification Using Distance-Based Approach
Authors: Hartanto Widhi , Setiawan Noor Akhmad , Adji Teguh Bharata
Published: July 2021

The recommendation system is a method for helping consumers to find products that fit their preferences. However, recommendations that are merely based on user preference are no longer satisfactory. Consumers expect recommendations that are novel, unexpected, and relevant. It requires the development of a serendipity recommendation system that matches the serendipity data character. However, there are still debates among researchers about the available common definition of serendipity. Therefore, our study proposes a work to identify serendipity data's character by directly using serendipity data ground truth from the famous Movielens dataset. The serendipity data identification is based on a distance-based approach using collaborative filtering and k-means clustering algorithms. Collaborative filtering is used to calculate the similarity value between data, while k-means is used to cluster the collaborative filtering data. The resulting clusters are used to determine the position of the serendipity cluster. The result of this study shows that the average distance between the recommended movie cluster and the serendipity movie cluster is 0.85 units, which is neither the closest cluster nor the farthest cluster from the recommended movie cluster.

Turbo snails have important roles in the ecosystem as prey for predators, and decomposition of dead objects, and it is starting to decrease. This is quite worrying so that conservation efforts must be carried out immediately. Turbo snail species found in Sepanjang Beach, Gunungkidul are Turbo crassus and Turbo setosus. The aims of this study were to determine food preferences, the relationship between body size and fecundity, analyze egg quality based on proximate levels of the two species, and meat proximate of T. crassus and T. setosus. Samples were taken from Sepanjang Beach, Gunungkidul. Food preference was observed using the sedgwick rafter, fecundity was counted using the gravimetric method. Moisture content, protein content, fat content, ash, and carbohydrate content of both species eggs and meat were determined with proximate analysis at the UGM Central Laboratory for Food and Nutrition Studies. The results showed that the dominant food for T. setosus was Phaeophyta, whereas the dominant food for T. crassus was Microcoleus sp. and Phaeophyta. The fecundity of both Turbo species is exponentially positively correlated with all body sizes. Proximate analysis showed that the levels of fat and protein in the eggs of both species were quite high, which meant that the eggs are in good quality. The conclusion of this study is both species have slightly different food preferences. The fecundity of both species will increase exponentially with increasing body size and the broodstock of T. crassus and T. setosus Sepanjang Beach has good quality.

We have seen that business can be done amid lockdowns and curfew restrictions. The pandemic having a lot of negative impact on almost everyone has a silver lining, which is the digital age. India could not have been more digital than it has been in the past one year from online grocery shopping to food delivery and the WFH culture is sure to promote people from ordering things from the comfort of their homes. In coming times the restrictions will become preferred choices and our average shopkeeper needs to be more tech savvy but it is next to impossible for every shop to go digital the way things are. In order to meet the requirements of the time we have proposed a solution in the form of a mobile application which will provide users to order food and services from the comfort of their homes.

Self-driving cars became a trending subject with a big improvement in technologies within the last decade. The project aims to coach a neural network to drive associate degree autonomous automobile agent on Udacity’s automobile Simulator's tracks. Udacity has discharged the machine as ASCII text file computer code and enthusiasts have hosted a contest (challenge) to show an automobile the way to drive victimisation solely camera pictures and deep learning. Autonomously driving an automobile needs learning to regulate steering angle, throttle and brakes. The activity biological research technique is employed to mimic human driving behaviour within the coaching model on the track. which means a dataset is generated within the machine by a user-driven automobile in coaching mode, and therefore the deep neural network model then drives the automobile in autonomous mode. 3 architectures area unit compared regarding their performance. Though the models performed well for the track it had been trained with, the important challenge was to generalize this behaviour on a second track out there on the machine. The dataset for Track_1, that was straightforward with favourable road conditions to drive, was used because the coaching set to drive the automobile autonomously on Track_2, consisting of sharp turns, barriers, elevations, and shadows. Image process and completely different augmentation techniques were accustomed tackle this downside, that allowed extracting the maximum amount data and options within the knowledge as doable. Ultimately, the automobile was ready to run on Track_2 generalizing well. The project aims at reaching an equivalent accuracy on period of time knowledge within the future.
Uma literatura do corpo em Perto do coração selvagem
Authors: Nogarotto Pâmela , Sales Cristiano De
Published: July 2021

Este ensaio argumenta que o romance de estreia de Clarice Lispector, Perto do coração selvagem (1943), traz à tona uma literatura para ser experienciada com o corpo em seus vários níveis de criação, a saber, o corpo da personagem, Joana, o corpo do texto e o corpo do leitor. A noção de corpo que adotamos é a do filósofo francês Maurice Merleau-Ponty. A concepção de texto e de linguagem aproveitamos de ensaios de Roland Barthes. Sem reduzir a leitura do romance a mero pretexto para verificação de intuições teóricas, defendemos que importantes traços de toda a trajetória da autora já estão tensionados nesse primeiro livro, sendo o principal deles o reconhecimento de que o alcance artístico da linguagem está em seu aparente fracasso. Fazemos isso por meio de leitura apurada do referido romance.

Published: July 2021

O Departamento de Educação Física do Estado de São Paulo (DEF-SP) suspendeu suas atividades oficiais durante a guerra civil de 1932 e passou a recrutar esportistas para a luta armada. A pesquisa teve por objetivo descrever o envolvimento do DEF-SP na guerra, analisar as narrativas publicadas pela imprensa paulistana sobre o alistamento e a participação dos esportistas e identificar as estratégias empreendidas para a construção de uma memória para o evento. Conclui-se que o DEF-SP centralizou as ações de clubes e federações esportivas para prestar apoio à luta armada e formar três tropas paramilitares. A imprensa atribuiu valores físicos e morais ao esporte para fomentar sentimentos regionalistas entre a população e afirmar uma identidade paulista. Dois anos após o armistício, foi fundada a Associação Cívica Primeiro Batalhão Esportivo para estabelecer uma memória triunfalista ao levante armado dos esportistas.
HUMILLACIÓN, EDUCACIÓN FÍSICA Y FORMACIÓN SUPERIOR EN CIENCIAS DE LA ACTIVIDAD FÍSICA Y EL DEPORTE: UNA AUTOETNOGRAFÍA MODERADA
Authors: Oliver Marta , Pérez-Samaniego Víctor , Monforte Javier
Published: July 2021

En Educación Física, el alumnado con baja competencia motriz puede verse humillado. La humillación suele quedar silenciada dentro de las personas que la sufren. Este artículo pretende sacar a la luz los sentimientos de humillación de una alumna de Ciencias de la Actividad Física y el Deporte (CCAFD). Para ello, la alumna ofrece un relato autoetnográfico que representa sus experiencias de manera semi-ficcional. Dentro del espectro autoetnográfico, se adopta una posición moderada. Tras justificar dicha posición, el artículo presenta algunas reflexiones acerca de cómo el campo de la educación físico-deportiva, y en particular los estudios de CCAFD, generan prácticas y sentimientos de humillación. Se destaca el rol de dos ideologías presentes en Educación Física: la ideología del rendimiento y el sexismo. El artículo concluye resaltando la necesidad de incentivar una sensibilidad ideológica que permita considerar aspectos didácticos, organizativos y evaluativos de las prácticas físico-educativas desde el prisma de la humillación

Published: July 2021

Companies engaged in the creative industry right now are implementing employee empowerment as one step in the organization to participate more effectively and make things work well (Siachou & Gkorezis, 2018). Empowerment teaches how employees make decisions and accept responsibility for the results of what they do. Related to the issue of development and creative economic growth, what are the organization’s efforts towards employees in creative industry companies through empowerment employee (McRobbie, 2016)? This study aims to determine employees’ perceptions of employee empowerment and the impact of empowerment on creative business. This research is qualitative research with a case study approach. The subject of the research is 18 employees at the company Janur Biru, Surakarta. Data collection was done through interviews, observations, and review of documents. Long-time observation and research take about 6 months. Research data are analyzed by classifying data based on various data available, then connecting with data and information obtained from literature, documents, surveys, interviews, and field observation. Based on the results of research conducted at Janur Biru about employee empowerment, it can be concluded, that overall empowerment for employees is good. The most dominant employee empowerment is accountability. The dimensions of desire are generally good. However, the lack of creative encouragement for employees to think about work strategies is because work strategies are still being made by leaders
La Metáfora como vehículo de la verdad
Authors: Montoya-Carvajal Juan Fernando
Published: July 2021

La escritura es una forma de manifestación del ser, buscando plasmar ideas a través del tiempo y a lo largo del mapa conceptual que nos rige, abriéndose una posibilidad de expresión a través del pensamiento y difundiéndose mediante el lenguaje. Dentro de las posibilidades de manifestación literaria, la filosofía es un tipo de escritura, en la cual se abordan estructuras con una terminología propia y en general, una búsqueda de la verdad sin dejar la ansiedad por la construcción del conocimiento del ser. La búsqueda infinita de la verdad es lo que hace al filósofo preguntarse por las cosas desde y hacia el ser, con el fin de trascender las formas, abarcando las diversas instancias definidas por los marcos de la realidad y atravesando las coyunturas históricas que construyen las circunstancias.
The Modern Approach to Guide Surgical Coronary Revascularization
Authors: Tolegenuly Almas
Published: July 2021

Coronary revascularization is crucial in the treatment of ischemic heart
disease (IHD) patients because it relieves symptoms with managing
adverse outcomes, including myocardial infarction (MI). To decide on
revascularization of the coronary artery, it is necessary to have
diagnostic evidence, since only the coronary vessels causing ischemia
must be selected for revascularization. Hence, in order not to subject
patients to unnecessary revascularization and to treat with medical
therapy, accurate measurements of the significance of coronary artery
stenosis are necessary. Identifying stenoses that cause ischemia should
be achieved in a variety of ways that include invasive and non-invasive
tests. Cardiologists use a combination of these investigations together
for optimal further treatment. The purpose of this review was to
describe publicly available data on recommendations to guide surgical
coronary revascularization.

The dynamic of SARS-CoV-2 and other respiratory virus in children and
adolescents is relevant in clinical context. There are few studies
comparing clinical course in COVID-19 (coronavirus disease) and other
respiratory virus in pediatric patients. The aim of this study was to
compare demographics and clinical features, exams abnormalities, and
outcomes in SARS-CoV-2 and other respiratory virus infections in a
pediatric population. This was a single-center prospective study,
between April 17 to September 30, 2020. We evaluated 76 pediatric
COVID-19 and 157 other respiratory virus infections. Rhinovirus occurred
in 132/157(84%). COVID-19 patients were significantly older, had more
fever (69% versus 50%; p=0.01), pneumonia (22% versus 5%;
p<0.01), myalgia (29% versus 8%; p=0.001), headache (31%
versus 14%; p=0.01) and worse outcomes than those with other
respiratory virus infections. Our data emphasizes differences in
clinical presentation and outcomes between pediatric COVID-19 and
rhinovirus infections.
A Constitutive Stress Response is an Adaptation to Low Temperature in the Antarctic green alga Chlamydomonas sp. UWO241

Published: July 2021

The Antarctic green alga Chlamydomonas sp. UWO241 is an obligate
psychrophile that thrives in the cold (4-6°C) but is unable to survive
at temperatures ≥18°C. Little is known how exposure to heat affects its
physiology or whether it mounts a heat stress response in a manner
comparable to mesophiles. Here, we dissect the responses of UWO241 to
temperature stress by examining its growth, primary metabolome and
transcriptome under steady-state low temperature and heat stress
conditions. In comparison with Chlamydomonas reinhardtii, UWO241
constitutively accumulates metabolites and proteins commonly considered
as stress markers, including soluble sugars, antioxidants, polyamines,
and heat shock proteins to ensure efficient protein folding at low
temperatures. We propose that this permanent stress metabolism is an
adaptive advantage to life at extreme conditions. A shift from 4°C to a
non-permissive temperature of 24°C alters the UWO241 primary metabolome
and transcriptome, but growth of UWO241 at higher permissive
temperatures (10°C and 15°C) does not provide enhanced heat protection.
UWO241 also fails to induce the accumulation of HSPs when exposed to
heat, suggesting that it has lost the ability to fine-tune its heat
stress response. Our work adds to the growing body of research on
temperature stress in psychrophiles, many of which are threatened by
climate change.
Generation of sequences of strong electric monopulses in nitride films
Authors: Grimalsky Volodymyr , Koshevaya Svetlana , Escobedo-Alatorre Jesus , Kotsarenko Anatoliy
Published: July 2021

This paper presents theoretical investigation of the excitation of the
sequences of strong nonlinear monopulses of space charge waves from input
small envelope pulses with microwave carrier frequencies due to the negative
differential conductivity in n-GaN and n-InN films. The stable numerical
algorithms have been used for nonlinear 3D simulations. The sequences of the
monopulses of the strong electric field of 3 - 10 ps durations each can be
excited. The bias electric field should be chosen slightly higher than the
threshold values for observing the negative differential conductivity. The
doping levels should be moderate 1016 -1017 cm-3in the films of ? 2 mm
thicknesses. The input microwave carrier frequencies of the exciting pulses
of small amplitudes are up to 30 GHz in n-GaN films, whereas in n-InN films
they are lower, up to 20 GHz. The sequences of the electric monopulses of
high peak values are excited both in the uniform nitride films and in films
with non-uniform conductivity. These nonlinear monopulses in the films
differ from the domains of strong electric fields in the bulk
semiconductors. In the films with non-uniform doping the nonlinear pulses
are excited due to the inhomogeneity of the electric field near the input
end of the film and the output nonlinear pulses are rather domains.

Published: July 2021

Intrusion detection system (IDS) is one of the most important components
being used to monitor network for possible cyber-attacks. However, the
amount of data that should be inspected imposes a great challenge to IDSs.
With recent emerge of various big data technologies, there are ways for
overcoming the problem of the increased amount of data. Nevertheless, some
of this technologies inherit data distribution techniques that can be a
problem when splitting a sensitive data such as network data frames across a
cluster nodes. The goal of this paper is design and implementation of Hadoop
based IDS. In this paper we propose different input split techniques
suitable for network data distribution across cloud nodes and test the
performances of their Apache Hadoop implementation. Four different data
split techniques will be proposed and analysed. The techniques will be
described in detail. The system will be evaluated on Apache Hadoop cluster
with 17 slave nodes. We will show that processing speed can differ for more
than 30% depending on chosen input split design strategy. Additionally,
we?ll show that malicious level of network traffic can slow down the
processing time, in our case, for nearly 20%. The scalability of the system
will al so be discussed.

resonators which are connected at the upper side, provide a lowpass filter
characteristics. In order to achieve combined lowpass with dual passband
response two L-shape stubs are incorporated into the lowpass filter
structure. The parametric analysis of the proposed filter has been carried
out using CST microwave studio. The numerical result shows a 3-dB cutoff

Published: July 2021

A field experiment was conducted in Eastern Tigray, Ethiopia, during the
summer season to determine the effects of flower removal and earthing up
time on the tuber yield and quality of potato (Solanum tuberosum L.). The
experiment comprised three flower removal stages and five earthing up time
treatments, which were laid out in a randomized complete block design (RCBD)
of a 5x3 factorial arrangement with three replications. Data collected on
tuber yield and quality parameters were analyzed using SAS version 9.2. The
interaction of flower removal stages and earthing up time treatments
affected marketable and unmarketable tuber number and yield, total tuber
number and yield, large-sized tuber weight, and number of large-sized
tubers. The medium and small-sized tubers were also affected by main
treatments but not by their interaction treatments. Similarly, dry matter
content was significantly (p<0.05) affected by flower removal alone, but not
by earthing up time and its interaction with flower removal. Generally, the
highest marketable tuber yield (30.25 t ha-1), large-sized tuber weight
(424.9 g), the number of large-sized tubers (5), and total tuber yield
(30.96 t ha-1) were recorded in the treatment of potato flower removed at
the bud stage and earthed up at 15 days after complete emergence. Therefore,
the removal of potato flowers at the bud stage and earthing up at 15 days
after complete emergence and common cultivation can be practiced for better
tuber yield and quality of potato.
Effects of the carbonated drink as an extender on semen characteristics, fertility and hatchability in Nigerian indigenous chicken
Authors: Oluwatoba Adeyina , Samuel Akanbi , Mathias Okukpe , Ibidapo Alli
Published: July 2021

Semen extenders are liquid diluents that buffer sperm cells and preserve
their fertilizing potentials. The commercial carbonated drink (CD) as an
extender was evaluated on semen characteristics, fertility and hatchability
in Yoruba ecotype chickens (YECs). The fructose of the CD was 1.52?0.05
mg/ml. Under the conditions of 370Celsius, 5% and 10% of CD were added to
the egg yolk citrate solution to make 100%. Semen was obtained from ten
matured Yoruba ecotype chicken cocks with an average weight of 1.8?0.2 kg.
The semen was pooled in a test tube and added to the extenders for
preservation at 0, 30 and 60 minutes, respectively, in a factorial design
layout. Percentage motility of sperm cells was significantly (p<0.05) higher
in 5% CD inclusion compared with 10% CD inclusion and control. Motility
decreased with an increase in preservation time across the treatments. The
percentage of dead sperm cells decreased (p<0.05) in 5% CD inclusion when
compared with 10% CD inclusion and control. The sluggish sperm percentage
increased significantly (p<0.05) with semen preservation time. Fertility and
hatchability of eggs were significantly (p<0.05) higher in 5% CD inclusion.
It was concluded that carbonated drinks at 5% inclusion in an extender could
preserve cock sperm cells for 60 minutes with improved fertility and
hatchability of eggs.
Testing the effects of the presence of uranium in drinking water from individual wells in the village of Dubravica in the Branicevo district on public health
Authors: Rajkovic Milos , Stojanovic Mirjana , Milojkovic Sladjana , Vukadinovic Melina
Published: July 2021

The village of Dubravica is partially located over the western lignite
deposits of the Kostolac basin. The examination of the dry residue obtained
from drinking water from two individual wells by X-ray diffraction analysis,
based on a typical peak, showed the presence of uranium in drinking water.
The indirect method by Rajkovic and associates showed that, in sample I, the
concentration of uranium in drinking water was 85.5 percent higher (3.71
?g/L) and that the concentration of uranium in sample II was only 22 percent
lower (1.56 ?g/L) than the Maximum Allowable Concentration (MAC) values
required by the Regulations (2 ?g/L). Analysis of the result of the
introduction of uranium in the human body has shown that this way brings
0.84 to 2 mg of uranium in the human organism per annum or 0.09 to 0.22 mg
of uranium is deposited annually in the kidney. Assessment of the potential
health risk due to the presence of uranium in drinking water indicated that
the population using drinking water from wells will be threatened by uranium
in a short time interval. Regarding the long-term risk, the calculation has
indicated that in the first sample of drinking water, about 25 inhabitants,
and in the case of the second sample of drinking water, 10 inhabitants out
of 1000 inhabitants are endangered. As the kidney is the organ in which
uranium is deposited (accumulated) to the greatest extent, its presence
causes weakening and failure of kidney function, which can destroy 75
percent of kidney function until the manifestation of the first clinical
symptoms. This phenomenon is observed among the population along the rivers
the Kolubara, the Drina, the Sava and the Morava and is called endemic
nephropathy. The elements found in trace amounts (Pb, Cd, Si), live agents
(bacteria and viruses), fungal plant toxins, genetic factors and immune
mechanism can be listed as possible causes. However, uranium in drinking
water has not been listed so far. The tests performed in this study clearly
show the role of uranium in the epidemic, endemic nephropathy, which is
growing and which is not at the acute phase of the disease but has already
progressed to renal failure and end-stage kidney disease. Official data on
the rise of endemic nephropathy and diabetes and increasing their share in
diseases, as well as overall mortality rates, which amount to 18.19%,
clearly indicate that the role of uranium in the Branicevo district
environment should not be ignored. Since there are settlements on the
terrain to be investigated, uranium and its migration through the
environment must be monitored as all conditions for its migration are
unfortunately favourable.

additive ratios were also produced to make the comparison systematically.
Also, the Vickers hardness measurements were carried out and a significant
increase in hardness was attained for both ANZ and ANC composites. The
average hardness value around 24.8?1.0GPa was measured for the ANZ and ANC
composites which means ~15% improvement compared to the pure Al2O3. Between
all the compositions, the maximum force (Fmax) value was obtained for the
ANZ (for 12 J impact energy level Fmax = 26617N) according to the low energy
drop weight impact test results. Tensile radial crack network formation,
cone formation, fracture and crushing of the cone structure were observed as
damage mechanisms for all compositions. The volume of conical frustum
structure was evaluated for each composition and the effect of
microstructure on possible ballistic performance was also discussed.
Gender differences in perception of the appropriate maturity age for men and women: Age norms of reproduction-related life events between the social context and evolutionary foundations
Authors: Todosijevic Bojan , Ignjatovic Suzana
Published: July 2021

The paper explores gender differences in the perception of appropriate age
for reproduction-related life events. Evolutionary theory suggests that age
norms are shaped by gender-specific evolutionary challenges. We tested two
hypotheses based on the evolutionary rationale. Hypothesis 1 suggests that
both men and women believe that women should reach maturity and experience
reproduction-related life events earlier than men. Hypothesis 2 claims that
men and women demonstrate this tendency asymmetrically. When women estimate
the appropriate/ideal age for men, they suggest a higher appropriate age for
men than men themselves. When men estimate the appropriate/ideal age for
women, they suggest a younger age for women compared to women themselves. In
the second part of the paper, we explored the background of these claims by
testing the alternative explanations based on social forces (culture,
socio-economic status, education, age, values). The hypotheses were tested
using the 9th wave of the European Social Survey (ESS) data, totaling around
47 thousand respondents and the sample of Balkan countries was analyzed in
more detail. The appropriate age was measured using ?ideal age? as the
concept which reflects the optimal timing expectations for
reproduction-related events: living with a partner, marriage, and
parenthood. Respondents were also asked to make judgments about the
appropriate age of becoming an adult for men and women. The overall results
supported the outlined expectations based on the evolutionary approach.
Measuring the trust in the European values study and the European social survey
Authors: Besic Milos
Published: July 2021

In this paper, we compare the latent construct measurement of political and
interpersonal trust in two researches: the European Values Study and the
European Social Survey. The main goal was to estimate the validity of
measuring the respective concepts. In order to achieve this goal, we
conducted a number of Principal Component Analyses and Confirmatory Factor
Analyses. Additionally, we used multilevel regression modelling to test and
compare the effect of socio-demographic variables on political and
interpersonal trust in both researches. We identified that socio-demographic
predictors had a similar effect on both types of trust. The paper is
complemented with descriptive data that portray the differences among
countries when it comes to interpersonal and political trust.
Scripting languages for geomorphological modelling and topographic visualization of Serbia
Authors: Lemenkova Polina
Published: July 2021

Scripting cartographic technique is a new method of geospatial data
visualization - especially with thematic mapping such as geomorphological
models. The purpose of this study was to explore the use of Generic Mapping
Tools (GMT) and R for geomorphological and topographic mapping of Serbia
using free open datasets (DEM, SRTM/ GEBCO, OpenStreetMap). Current trend in
education and research of distance-based and online-based education suggests
that application of free high-resolution data for modelling and mapping by
open source cartographic toolsets are more likely to result in deep
geospatial analysis of the geomorphology of Balkans with associated
geographic phenomena: hydrology, soils, vegetation, geology. Presented
fragments of scripts aim to demonstrate the technical usage of R and GMT
coding in cartographic workflow with a case study on Serbia. Using
qualitative descriptive cartographic approach to visualize the slope, aspect
and terrain elevations over the country and the ?raster? package provided by
R, it was found that the geomorphology of Serbia spatially differs in
southern and northern parts of the country resulting in regional geologic
evolution and tectonic dynamics of the Balkan formation. The presented maps
portrayed general distribution of the landforms in Serbian region of
Balkans. The research contributes to the methodological development and
testing of the cartographic techniques as well as geomorphological and
environmental studies of Serbia.

Published: July 2021

Biodiversity and biodiversity preservation are some of the most important
topics in ecology. Protecting biodiversity in urban ecosystems is especially
challenging. Urban parks are a valuable part of green infrastructure in
cities, as they contribute to preserving natural habitats for many species.
Biodiversity can be quantified by calculating different diversity indices,
and in this paper, we have calculated alpha indices (Shannon, Simpson,
Fisher, Berger-Parker and Margalef index) and beta indices (Sorensen index,
Jaccard distance and Bray-Curtis index) for the Futog park in Novi Sad,
Serbia, within two periods, 2005 and 2020. The goal of the paper is to
analyze the current values of biodiversity indices in the park and compare
them with the ones from 15 years ago. In addition to the analysis of
biodiversity indices values, the paper provides the comparison of taxonomic
structure of flora, and the abundance of native, endemic and invasive
species in the park, in 2005 and 2020. The results show that the values of
biodiversity indices have decreased in the indicated period of time, and one
of the main causes can be related to the spread of invasive species within
the park. For calculation purposes, we have used the R program and the R
package ?vegan?.
Deep Space Neck Infections

Published: July 2021

Deep neck space infections are a common reason for otolaryngology consultation. The anatomic spaces and their relationships are complex, and inappropriately treated infections may pose life-threatening consequences. It is critical for the practicing otolaryngologist to understand the boundaries and contents of the fascial spaces, microbiology of involved organisms, clinical workup, indications for medical and surgical management, and potential complications.

NORMAS TRIBUTÁRIAS COMO INSTRUMENTO DE INFRAÇÃO À ORDEM ECONÔMICA (INTERNA E INTERNACIONAL)
Authors: Almeida Victor Monteiro
Published: July 2021

Cotidianamente as doutrinas especializadas ofertam estudos de suas respectivas searas isoladamente, sem perquirir as repercussões que cada fenômeno sucedido em determinada ramo do direito ocasiona reflexamente nas demais égides. A digressão científica proposta partirá da premissa de que o sistema do direito positivo é uno e indecomponível, para então se debruçar sobre as consequências que as anomalias protagonizadas pelas normas prescritivas de regras tributárias surtem sobre a ordem econômica. Fixar-se-ão pressupostos elementares para, a partir deles, desenvolver toda a linha de raciocínio que conduzirá à conclusão. Na conclusão, socorrer-se-á de exemplos práticos buscando identificar as consequências práticas do estudo teórico abordado, indicando de que forma as normas tributárias podem instrumentalizar infrações à ordem econômica (interna e internacional).

A PROTEÇÃO DOS DIREITOS HUMANOS AOS DENUNCIANTES QUE INVESTIGAM ATOS DE CORRUPÇÃO
Authors: Notari Marcio Bonini
Published: July 2021

A corrupção vem se apresentando no âmbito das instituições privadas e democráticas, assim como, a nível internacional, entre os setores público e privado. No início da década de 90, começam a surgir uma série de estudos por parte dos organismos internacionais, das agências multilaterais e das organizações não governamentais procurando fornecer uma programação globalizada com temas ligados aos direitos humanos. São inúmeras denúncias noticiadas nos meios de comunicação acerca das práticas corruptivas, o que, acarreta no uso de campanhas anticorrupção por parte de governos para repressão a todos aqueles opositores ou críticos da sua gestão. Isso, de certo, modo pode trazer restrições aos direitos dos denunciantes, contribuindo para violação aos direitos humanos de todo e qualquer pessoa identificada como objetivo político, da transparência e publicidade, da liberdade de expressão e pensamento.  O presente trabalho pretende analisar a proteção dos direitos humanos em seus tratados e convenções internacionais, no que diz respeito aos denunciantes e de todos aqueles que investigam casos de corrupção ligados a ilícitos, práticas fraudulentas em organizações de natureza pública e privada. De tal modo que, a participação do cidadão  mediante o livre exercício da liberdade de expressão e do acesso á informação, possibilita o exercício da cidadania, sem censura estatal, como forma de diminuir a incidência dos atos de corrupção e um controle benéfico ao poder público e a iniciativa privada.

Busca-se, desta forma, delimitar e visualizar a linha tênue entre o fomento ao desenvolvimento socioeconômico e a degradação do meio ambiente, dentro do paradigma de uma Sociedade de Risco. Faz-se uma análise mais específica no que diz respeito aos alimentos geneticamente modificados, de modo a buscar uma decisão balanceada entre os seus benefícios e as irreversibilidades dos danos causados por estes.
GLOBALIZAÇÃO E CONTRATO SOCIAL: CRISE E TURBULÊNCIA NO SÉCULO XXI
Authors: Porto Dora Nogueira
Published: July 2021

A proposta deste artigo é repensar os riscos corridos pelo contrato social na área jurídica econômica e social numa época em que a turbulência gerada pela Globalização do Século XXI deixa em crise o pensamento, os antigos paradigmas e a própria sociabilidade. Não estão firmados ainda novos paradigmas e por isso nos sentimos órfãos de verdades absolutas, seguimos caminhando nas incertezas e em meio à grande vulnerabilidade. Se por um lado, a turbulência pode ser vista como positiva para revermos nossas crenças e nossas verdades tidas como absolutas, por outro, nos deixa na indefinição de dois mundos: o do modelo da modernidade do século XX e o do desafio da pós modernidade gerada pela globalização de fins do século XX e inícios do século XXI.
