Microstructural Analysis and Antibacterial Response of Zn2+/Mg2+ Dual Doped β-Tricalcium Phosphate Bioceramics
Authors: Alshemary Ammar Zeidan , Qasim Huda Basim , Saleh Ali Taha
Published: April 2022

This article evaluates the impact of the addition of zinc (Zn) and magnesium (Mg) on the structural, morphological, and antibacterial characteristics of β-tricalcium phosphates (hereafter called Zn/Mg-βTCP) prepared using the microwave (MW) assisted wet precipitation method in which the Ca deficient apatite [Ca9-(x+y)MgxZny(HPO4)(PO4)5 (OH)] was calcined for 2 h at 1000 °C. The prepared samples were characterized using XRD, FTIR, and FESEM measurements. The XRD patterns of the samples showed a steady decrease in the lattice parameters with an increase in Mg2+ and Zn2+ content. The FESEM images of the samples disclosed the morphological changes due to the Mg2+/Zn2+ co-doping. The inclusion of Mg2+ and Zn2+ into the βTCP was shown to induce excellent bioactivities that were absent in the pristine βTCP. Enhancement, coupled with good antimicrobial properties against Escherichia coli (E. coli), suggests that Mg2+/Zn2+ co-doping TCP can be developed further into antibacterial bone cement. As synthesized, it would be considered a potential biomaterial for orthopedic applications.

Authors: Shen Shih-Chi , Chang Wu-Hua , Shih Yi-Yu , Chang Chih-Hsiung
Published: April 2022

With the opening of the establishment of new banks in the 1990s, it led to an excessive number of domestic bankers and an excessively small scale, which caused a decline in the quality of financial assets and eventually resulted in adverse selection and moral hazard under information asymmetry in the domestic cash card market, triggering a card debt crisis and serious social problems. This article examined whether the phenomenon of information asymmetry was improved after the competent authority intervened. The results highlighted the important position of the competent authority in financial institution management and made information asymmetry improved eventually.

Authors: Del Castillo Vázquez Roxana Mitzayé , Parga-Fuentes Carolina , Duran-Toribio José M. , Calles Alipio
Published: April 2022

In this review, we explore the bidimensional materials based on phthalocyanine molecules. The phthalocyanine molecule is used as a brick for the construction of new bidimensional materials. In particular, the phthalocyanine molecules can be placed at each vertex or sharing edges to form tessellations. The tessellations available are constrained to the four-fold type of the phthalocyanine molecules and can be a mix of several polygons to increase the number of possibilities. Computationally, the popular tessellations used are the Archimedean tiling, but many others expect to be discovered and well-studied. Different tessellations will provide new symmetric systems to explore. Each new symmetry pattern will modify the physical and chemical properties of the new bi-dimensional material. These new materials present many exciting applications as capture and storage of greenhouse gases and molecular electronic devices. In the present review, we summarized some of these tessellations and the many applications that they can have.

Published: April 2022

Abstract: Nowadays, new Artificial Intelligence (AI) and Deep Learning based processing methods are replacing traditional computer vision algorithms. On the other hand, the rise of the Internet of Things (IoT) and edge computing, has led to many research works that propose distributed video-surveillance systems based on this notion. Usually, the advanced systems process massive volumes of data in different computing facilities. Instead, this paper presents a system that incorporates AI algorithms into low-power embedded devices. The computer vision technique, which is commonly used in surveillance applications, is designed to identify, count, and monitor people's movements in the area. A distributed camera system is required for this application. The proposed AI system detects people in the monitored area using a MobileNet-SSD architecture. This algorithm can keep track of people in the surveillance providing the number of people present in the frame. The proposed framework is both privacy-aware and scalable supporting a processing pipeline on the edge consisting of person detection, tracking and robust person re-identification. The expected results show the usefulness of deploying this smart camera node throughout a distributed surveillance system.

A Research paper on Auto Controlling Irrigation System Using Arduino UNO
Authors: K S Joji Mitto , Savant Dr. Preeti
Published: April 2022

Abstract: The rise in population has resulted in food and water shortages in the modern period. So, in order to avoid this situation, we must promote agriculture. Water loss, on the other hand, is more typical in this sector, with irrigate logging happening as irrigation is utilized to water agricultural crops. As a result, an automated plant irrigation system for adequate water delivery in the fields must be created. This article discusses a fully automated irrigation system that monitors soil moisture content and determines whether or not irrigation is necessary, as well as how much water the land requires. The Arduino UNO microcontroller is used in this setup. It has been programmed to monitor the soil's moisture content over time. When the moisture content falls below a specified threshold, it will start supplying the required amount of water until the threshold is attained. As a consequence, when the soil is dry, the pump will automatically water the fields; when the soil is moist, the pump will switch off, decreasing the need for personnel and saving time. Keywords: Arduino UNO, Irrigation, Moisture.

Authors: Singh Manthan , Kumar Dr. Sachin
Published: April 2022

Abstract: New needs are being created regularly as a result of technology improvements. The internet is one of these tools. To take it a step further, they created the Internet of Things (IoT), which is used to connect smart objects to the internet to facilitate communication. It is linked to the cloud, which stores all of the data created by it, allowing smart devices to operate more efficiently. This further enhances the advantages of the item. Smart devices communicate with edge servers, which are located close to them and capable of performing communication and security functions. With this thesis, an attempt is made to shorten the amount of time it takes to search in a secure cloud on an edge server. The discoveries that have been proposed allow for an extension of time without jeopardizing security issues. This creates a more user-friendly interface for securely engaging with and exchanging data, as well as searching for and downloading data from a secure server in less time, all while maintaining security.

Published: April 2022

Abstract: COVID-19 (SARS-CoV-2) was the reason for causing a pandemic all over the world which created many problems and challenges for all countries. Increasing number of cases in every nation led the authorities of each country to put lockdown measures all over the nation. Although the lockdown implemented was to prevent the community from the spread of infection, but it had its own effect on mental as well as physical health and lifestyle of people. We devised a survey to focus on the physiological, psychological, and behavioural changes witnessed during the lockdown and to establish a correlation between the lockdown attributing to the negative changes developed during this period such as weight gain, increase in sleeping hours and screen time. All the data was gathered through a questionnaire via Google forms which was distributed to a substantial amount of people through social networking platforms. The responses received were 421 in total, which on analysis and comparison of the pre-lockdown and post-lockdown periods, showed trends like 58.5% people had increase in BMI, 33.9% people had increased more than 7 hours of daily screen time whereas 46.5% had a reduction of working hours down to less than 6 hours.

The Effect of Money Magnitude on Unfair Proposals and Decisions In Ultimatum and Dictator Games
Authors: Ye Nan , Wang Q Angqiang , Wang Zhiwei
Published: April 2022

To explore the effect of money magnitude in unfair decisions, participants accepted or rejected the allocation scheme proposed by the other participant/player in ultimatum games, or chose an allocation scheme to share a certain amount of money with the other participant/player in dictator
games. The results show that in ultimatum games, as the amount of money increased, when the level of unfairness remained constant for unfair decisions, participants (responders) were increasingly likely to reject the unfair allocation scheme; however, in dictator games, as the amount of money
increased, participants (proposers) allocated an increasing proportion of money to themselves. Thus, there is an effect of money magnitude in unfair decision processing. Participants' economic decisions were not entirely based on a social fairness preference, and the amount of money involved
had an important influence on their decisions about making or accepting unfair proposals.
A USUCAPIÃO ENTRE HERDEIROS COMO CONSECTÁRIA DA FUNÇÃO SOCIAL DA POSSE E DA PROPRIEDADE
Authors: Silvestre Gilberto
Published: April 2022

O presente artigo tem o objetivo de analisar a possibilidade de ocorrência da usucapião entre herdeiros em relação aos bens pertencentes ao acervo hereditário. A análise do presente objeto de pesquisa possui ampla relevância, na medida em que o Código Civil de 2002 não possui disposição expressa sobre a matéria, ocasionando amplas divergências na literatura jurídica e na jurisprudência. Para atingir o fim proposto, valeu-se de uma abordagem qualiqualitativa, a partir da análise estatística de julgados do Superior Tribunal de Justiça, Tribunal de Justiça de São Paulo, Tribunal de Justiça do Rio de Janeiro, Tribunal de Justiça de Minas Gerais e Tribunal de Justiça do Espírito Santo. A análise dos julgados demonstra que a maior parte dos julgadores entendem como possível a usucapião entre herdeiros, mas que a demonstração de todos os requisitos necessários para a comprovação da prescrição aquisitiva tem sido um desafio nos casos concretos.
CIDADANIA DIGITAL OU DITADURA ALGORÍTMICA? CONTRADIÇÕES DO MUNDO DIGITALIZADO E OS DESAFIOS DA REGULAÇÃO
Authors: Florêncio Filho Marco Aurélio , Ladeira Fernando
Published: April 2022

A inteligência artificial é um fenômeno que desafia o sistema jurídico. Por um lado, gerou uma maior capacidade de mobilização social decorrente da facilidade de comunicação e acesso à informação permitidos pela internet e redes sociais com a consolidação de uma nova conformação da democracia por amplos e eficazes mecanismos de pressão até então inexistentes, emergindo assim a cidadania digital. Por outro lado, a inteligência artificial transferiu poderes antes restritos ao Estado para as grandes empresas de tecnologia que detêm o controle da inteligência artificial e exercem vigilância das condutas individuais em substituição ao próprio poder público, o que se denomina ditadura algorítmica. O sistema jurídico, por seu turno, vê-se confrontado com a dificuldade de regular esse sistema tecnológico, seja pela incompreensão de sua linguagem, seja pela ineficácia dos métodos tradicionais confrontados com limites de soberania. As teorias dos sistemas de Luhmann e a da fragmentação das constituições sociais de Teubner permitem compreender a relação do Direito com a inteligência artificial e sugerem a experimentação de novos métodos para a promoção da regulação autorregulada.

Published: April 2022

A ideia de Startups se propagou com difusão da internet, que impôs ao mundo um novo modo de repensar o mercado. As Startups se desenvolveram e, consequentemente, diversificaram seu ramo de atuação pelo mundo afora. As cleantechs são espécies de Statups cuja atividade é focada na produção e no consumo sustentável. Assim, com objetivo de fomentar esse mercado emergente, muitos países, inclusive o Brasil, instituíram leis específicas que se destinam ao desenvolvimento desse setor da economia. Atualmente, as cleantechs constituem um novo modelo de empreendimento no mercado brasileiro. Num mesmo negócio essas empresas aliam os conceitos: desenvolvimento econômico de modo rentável e sustentabilidade. Nesse contexto, utilizando-se do método científico dedutivo, por meio da pesquisa de mudanças ocorridas na legislação e na mentalidade da sociedade no decorrer do tempo, inclusive doutrinas especializadas e julgados referente ao tema proposto, o presente estudo procura demonstrar como o Brasil concedeu inúmeros benefícios fiscais, por meio da edição de leis dos diversos entes federados, no intuito de intensificar o desenvolvimento de políticas públicas mais eficientes para a comunidade brasileira. Conclui-se que o estímulo a produção de energia fotovoltaica pode ser considerado mecanismo de enfrentamento da crise energética que afeta a maioria dos países, inclusive o Brasil. Ademais, mostrou-se um instrumento eficaz na promoção do desenvolvimento nacional.
VIOLÊNCIA CONTRA A MULHER: NECESSIDADE DE ATUAÇÃO PREVENTIVA E EDUCATIVA PARA O ROMPIMENTO DO CICLO DE VIOLÊNCIA DOMÉSTICA
Authors: Lima Carolina , Moreira Ingrid , Garcia Laura
Published: April 2022

Mesmo após anos da ratificação pelo Brasil de compromissos internacionais referentes à proteção dos direitos das mulheres e da edição da Lei Maria da Penha (Lei n. 11.340/06), a violência doméstica contra a mulher continua a ser uma realidade social dramática que a sociedade e o Poder Público brasileiro precisam enfrentar. Diante disso, o presente artigo se propõe a identificar as causas histórico-culturais intergeracionais dessa violência e, com isso, evidenciar as estratégias necessárias no campo da prevenção e da educação para romper com o ciclo de violência arraigado na sociedade brasileira e possibilitar, com a atuação do Poder Público, a maior proteção dos direitos humanos das mulheres. Para tanto, foi utilizada uma metodologia de pesquisa quantitativa e qualitativa, com a análise de dados estatísticos que apontam a magnitude da violência doméstica, assim como de referências bibliográficas nacionais e estrangeiras para a compreensão do fenômeno em sua integralidade. Com isso, foi possível concluir que, além da atuação estatal para promover políticas públicas nesse cenário, a educação em direitos humanos deve ser vista como o principal instrumento para romper o ciclo de violência doméstica contra a mulher. Tal investimento educativo deve ser amplo, seja para que as mulheres possam reconhecer a situação de violência em que se encontram e acionar o sistema protetivo, seja para que as crianças, desde a infância, aprendam sobre igualdade de gênero, seja para que os próprios agressores assumam a responsabilidade pelos seus atos e alterem o padrão comportamental agressivo.

Published: April 2022

INTRODUCCION:
El ataque cerebrovascular (ACV) de etiología isquémica es una patología cuya incidencia y mortalidad aumentaron en la última década. Cuando se maneja oportunamente, mediante trombólisis como terapia inicial, mejora su desenlace y funcionalidad. En el departamento del Tolima (Colombia) no hay registros de esta patología y en el país la bibliografía al respecto es limitada. El objetivo de este estudio es evaluar los desenlaces clínicos del manejo agudo con r-tPA en los pacientes que presentaron ACV isquémico en dos instituciones de la ciudad de Ibagué, capital de dicho departamento, entre junio del 2019 y junio del 2020, e identificar los tiempos de atención hospitalaria y las principales variables asociadas con el grupo de pacientes que fallecieron.

MATERIALES Y METODOS:
Estudio descriptivo de corte transversal del manejo del ACV isquémico con r-tPA, en el que se describen las variables sociodemográficas, la escala NIHSS como evaluación neurológica inicial, los tiempos de atención (inicio-aguja, puerta-tac y puerta-aguja), los desenlaces postoperatorios y el Rankin modificado al egreso.

RESULTADOS:
Se incluyeron 38 pacientes con una media de 67,37 años, el 60,53 % fueron mujeres. La escala NIHSS al ingreso fue 13,47 puntos (DE 5,24). Los tiempos de atención fueron 183 minutos (DE 72,63) inicio-aguja, 41 minutos (RIQ 17-72) puerta-TAC y 101,50 minutos (RIQ 77 - 137,25) puerta-aguja. La mortalidad fue del 23,68 %.

CONCLUSION:
La mortalidad y el desenlace funcional del ACV en nuestra población fueron similares a los reportados en la literatura nacional e internacional, sin embargo, es preciso implementar protocolos de atención del infarto cerebral para incrementar el número de pacientes con desenlace favorable, acortando los tiempos de atención en toda la cadena del tratamiento adecuado del infarto cerebral.

Authors: Villada-Ochoa Oscar Alonso , Pineda-Salazar David Antonio
Published: April 2022

INTRODUCCIÓN:
El trauma craneoencefálico (TCE) es una de las principales causas de daño cerebral y discapacidad en personas menores de 40 años. Según su severidad, se puede clasificar en leve, moderado o grave, en función de la escala de coma de Glasgow. Muchos pacientes quedan con secuelas neuropsicológicas y comportamentales que pueden afectar en mayor o menor grado su funcionalidad. El objetivo del estudio fue determinar las diferencias en el perfil neuropsicológico, las características clínicas y el compromiso funcional en pacientes con TCE según la clasificación de la severidad.

METODOLOGÍA:
Se realizó un estudio observacional, analítico, de corte transversal. Se revisaron las historias clínicas y los reportes neuropsicológicos de adultos con TCE evaluados por neuropsicología entre los años 2014 y 2019. Se compararon los resultados de pruebas neuropsicológicas, síndromes neuropsicológicos y funcionalidad según la severidad del TCE.

RESULTADOS:
Se estudiaron 48 pacientes, 38 de ellos hombres (73 %), con una mediana de edad de 35 años (RI: 25-51). En 14 casos el TCE fue leve, en 18 moderado y en 16 severo. El síndrome neuropsicológico más frente fue el amnésico (100 %), seguido del disejecutivo (79 %) y el compromiso en la atención (77 %). No se encontraron diferencias según severidad del TCE. Cuarenta y un pacientes (85 %) presentaron cambios comportamentales, 14 (29 %) experimentaron alteración en las actividades básicas de la vida diaria y 32 (68 %) en las actividades instrumentales.

CONCLUSIONES:
Las alteraciones neuropsicológicas, comportamentales y funcionales posteriores a un TCE son frecuentes, sin embargo, no se encontraron diferencias significativas según severidad del trauma.

Causality relationship between sustainability factors and water management: The emerging market study
Authors: Mukwarami Silas , Fakoya Michael Bamidele
Published: April 2022

This paper evaluates the causality relationship between sustainability factors and water management in the South African public sector. The quest to partake in this research is motivated by the need for addressing the prevailing water services delivery challenges (WSDCs) and infrastructure funding deficit challenges (Ruiters, 2013). Given the severity of WSDCs in South Africa, the question which needs redress is whether sustainability factors influence water management and vice versa. Therefore, the main objective of this paper is to explore a unique approach to addressing WSDCs by investigating the bidirectional relationship between sustainability factors and water management. Data spanning 2009–2019 on sustainability factors and water management was collected using quantitative content analysis from web-based sources of purposively selected eight metropolitan municipalities in South Africa. Using Granger non-causality tests, social and environmental management practices have had a bidirectional relationship with water management. Besides, causality analysis involving corporate governance and economic measures failed to produce outright opposite direction connections. The results suggest that stakeholders and policymakers should acknowledge the role of sustainability factors in addressing investment challenges confronting the water sector. Therefore, the study recommends further research into establishing the significance and direction of the relationship between sustainability factors and water management.

Objective: To evaluate the financial and non-financial conflicts of
interest (COI) among authors of Clinical Practice Guideline for
Obstetrics 2020 (OBCPG) and Clinical Practice Guideline for Outpatient
Gynecology 2020 (GYNCPG), relationship between quality of evidence and
strength of recommendations, and COI policies. Design: Cross-sectional
study Setting & Populations: All 103 guideline authors of OBCPG and
GYNCPG published by Japan Society of Obstetrics and Gynecology (JSOG) in
2020. Methods: Descriptive analysis and multivariate negative binomial
regression analysis. Main Outcome Measures: Personal payment data from
92 major pharmaceutical companies to the OBCPG and GYNCPG authors
between 2016 and 2019; and quality of evidence and strength of
recommendations underlying the guideline. Results: The 66.0% of the
authors received personal payments of $1,174,508 in total from 60
pharmaceutical companies between 2016 and 2019. The four-year combined
average payment per author was $11,403 (standard deviation: $22,056)
and the median was $2,010 (interquartile range: $0‒$8,902). For
analysis of references and recommendation, a total of 50.2% of
references were low quality of evidence. Only 21.4% of references were
high quality of evidence. Conclusions: This study found that the 66.0%
of Japanese obstetric and gynecologic CPG authors received personal
payments at least once during the CPG development period. 50.2% of
evidence supporting Japanese obstetric and gynecologic CPG were low
quality of evidence. There were no sufficient COI policies in JSOG, as
well as ACOG, comparing to the global standard COI policies for CPG
development. Funding: This study was funded in part by the Medical
Governance Research Institute.

Published: April 2022

Background: Epicardial pacemakers are known as an alternative
for endocardial pacemakers in some cases such as heart block, and
complex congenital heart diseases. Considering recent advances and
improvement of epicardial lead subtypes, it is essential to investigate
the long-term function of them. In this study, we aimed to assess the
sensing and pacing characteristics, and survival of bipolar
steroid-eluting and unipolar non-steroid-eluting epicardial pacemakers.
Methods: We conducted an entirely concentrated search on the
documents of all patients who had undergone epicardial lead implantation
in the Shaheed Rajaie Cardiovascular, Medical & Research Center during
2015-2018. Implant, and follow up data were extracted. Kaplan Meier
analysis and Weibull regression hazards model were applied for the
survival analysis. Results: eighty-nine leads were implanted
for 77 patients. Of the total leads, 52.81%, 53.93%, and 47.19% were
implanted in children (under-18-year-old), females, and patients with
congenital heart diseases, respectively. Bipolar steroid-eluting leads
comprised 33.71% of 89 leads. Pacing threshold of unipolar
non-steroid-eluting leads that were implanted on the left ventricle and
right atrium increased significantly during the follow up to greater
records than bipolar steroid-eluting leads. Survival analysis also
revealed that bipolar steroid-eluting leads are significantly better in
48-month survival (Weibull HR: 0.13 (95%CI, 0.02-0.99), p-value,
0.049). Age, ventricular location of the lead, and acute pacing
characteristics were not associated with survival. Conclusions:
Bipolar steroid-eluting epicardial leads have an acceptable survival
compared with unipolar non-steroid-eluting, without a significant
difference regarding patients age. Therefore, they could be an excellent
alternative for endocardial ones.
On Properties and Applications of a New Integral Transform to Solve Fluid Flow and String Vibration Problems
Authors: Hussain Manzoor
Published: April 2022

This work introduces a new integral transform for functions of
exponential order. Sufficient conditions for existence and uniqueness
are derived under suitable assumptions. Basic operational properties
such as linearity, scaling, shifting, convolution, and limiting behavior
are established. The transform of several elementary and generalized
functions and derivatives and integrals are obtained. Application of the
new transform is then illustrated in the solution of fluid flow and
string vibration problems. The obtained results are found to be true for
already existing results.

Effects of microforms on the evaporation of peat-bryophyte-litter column in a montane peatland in Canadian Rocky Mountain
Authors: Wang Yi , Petrone Richard
Published: April 2022

Peatland microtopography contains hummocks (local high points) and
hollows (local low points). Little is known about how the
evapotranspiration (ET) of peat (P), peat-bryophyte (BP), peat-litter
(LP) and peat-bryophyte-litter (LBP) columns varies with peatland
microforms. That is, whether there are fine-scale variations in peatland
evaporation, and if they are critical when being upscaled to the entire
peatland ecosystem is yet to be answered. This study found that ET was
significantly affected by cover type (P, BP, LP or LBP) and the
interaction effect of the cover type and microform, based on the field
evaporation experiments in a montane peatland in the Canadian Rocky
Mountains, during the growing season of 2021. Mean daily ET of P-Hummock
and P-Hollow is 14.16 and 11.76 g d , respectively;
BP-Hommock and BP-Hollow is 9.57 and 14.38 g d ,
respectively; LBP-Hummock and LBP-Hollow is 9.44 and 9.91 g d
, respectively; and evaporation of LP-Hummock and
LP-Hollow is 5.68 and 7.64 g d , respectively.
Peatland microform indirectly affected ET through interactions with
cover type, modifying the vertical profile of soil temperature, and
changing key environmental drivers of evaporation. Moreover, the ability
of two widely used models in modelling the spatial variation of peatland
evaporation were also tested. It was found that Penman-Monteith (P-M)
model and the bryophyte layer model in the Atmosphere-Plant Exchange
Simulator (APES) were able to yield satisfactory results based on field
measurements of soil temperature and soil moisture. This study supports
developing more practical evaluation tools on the hydrological state of
peatland ecosystems.
Adjustable Multi-band and Multi-load Wireless Power Transfer System Based on Frequency Splitting
Authors: Xia Nenghong , Lin Jialiang , Zhu Yimin , Zhang Fan , Li Huaishen
Published: April 2022

In magnetically coupled resonant wireless power transfer system, when
two or more coils work under over-coupling, the original resonant
frequency will split, thereby reducing the power transfer efficiency.
For multi-load systems with different operating frequencies, a
packetized multi-frequency wireless charging method based on frequency
splitting is proposed. Two adjustment modes, axial and lateral, are
designed for the adjustment coil. By adjusting the coupling coefficient,
it is possible to switch different groups of loads for charging. The
experimental results confirm that the two load coils receive 1.2W and
1.4W of power, respectively, when the proposed system is input with a DC
voltage of 10V.

Authors: Sulito Bogale , Hareru Werku
Published: April 2022

This research was carried out to consider the effect of different curing
methods on the performance of concrete for grade 25 of normal concrete.
The objective of this research was to determine the effect of different
curing methods on the performance of concrete. This study considers the
effect of five curing methods (air curing (B1), water submerged curing
(B3), spraying curing (B2), burlap curing (B4) and moist sand curing
(B5)) were used to evaluate the strength, carbonation, length change,
absorption, and sorptivity of concrete on 3rd , 7th, 14th, 28th and 56th
days at hot air temperature (18-390C) and medium air temperature
(11.2-32.70C). A total number of 210 cube and 30 prisms samples were
cast for all curing methods. The result indicated that water submerged
curing was the highest strength of concrete followed by the close
burlap, spraying, and moist sand curing methods of concrete. The air
curing was the lowest strength of concrete and carbonated concrete in
hot and medium air temperatures. The concluded weak positive correlation
between the strength and the density of concrete. The strength strong
negative correlation with length change, water sorptivity, and water
absorption of concrete at hot and medium air temperatures. Finally, the

Background/Aim. The competence of healthcare workers (HCWs) to advocate the importance of immunization to persons who are hesitant about vaccines is extremely important. The aim of this study was to evaluate the final-year medical students? competencies related to immunization challenges in their practice using their knowledge, attitudes, and study practices. Methods. The cross-sectional study was conducted among 442 final-year students of the Faculty of Medicine, University of Belgrade, Serbia. The instrument used for data collection was an anonymous questionnaire consisting of 38 questions. Hierarchical multiple regression analysis was conducted to identify the predictive value of different factors in immunization knowledge among medical students. Results. The median total knowledge score with the interquartile range was 7 ? 3.00 out of 13. There was a statistically significant positive correlation between the knowledge score and the grade point average (GPA) (r = 0.207, p < 0.001). Thirty-five percent of students felt moderately capable of conducting work regarding vaccination without supervision. Furthermore, 92.1% of students considered that additional training and information channels about immunization needed to be implemented in curricula for HCWs. The results of the hierarchical regression analysis showed that gender, age, GPA, study duration, self-confidence regarding immunization knowledge, the flu, and hepatitis B vaccination status explained a total of 36% of the variance in the immunization knowledge score. Less than two-thirds of students believed they had enough knowledge to reassure a person hesitant about immunization. Conclusion. The results of our study showed an average level of knowledge about immunization among final-year medical students. As less than two-thirds of students believe that they have enough knowledge to reassure a hesitant person, there is a need for a better understanding and improving the parts of the curricula of medical faculties regarding immunization.
