Authors: Putra Zainal , Muzakir Muzakir
Published: March 2021

This research aims to  find out the most competitive retail company operating in current global market based on the perspective of efficiency. A well-performed company is the company that is efficient in its operations. By using Data Envelopment Analysis (DEA) approach, this research differs from prior research because we used multivariable inputs, namely: asset, operational expense and the number of employees. The output variables used in this research are: total revenue, net profit, return on equity (ROE), return on assets (ROA), return on investment (ROI), dividend yield ratio and asset turnover ratio. The analysis results shows that six retail companies are “efficient” in its operation (efficiency score of 1.00), namely: Carrefour, Costco, Kroger Company, Home Depot Inc, JD.com Inc Adr and Alibaba Group Holdings Ltd ADR. Therefore, these companies are considered the most competitive in its operation strategy in the current global market, whereas there are four retail companies falls into category of “inefficient” (efficiency score < 1.00), namely: Walmart, Amazon.com Inc, Tesco PLC and Walgreens Boots Alliance Inc.

Authors: Mathew Josey , George Liza , Paul Sinju , Bastian Meera , Vineet RV , Varghese Tom P
Published: March 2021

Aim and objective

To evaluate and compare the depth of cure of two bulk-fill composites with a conventional composite.

Materials and methods

A sample size of 36 was taken and divided into three groups based on the type of composite. Standardized cylindrical stainless steel molds were prepared with 8 mm diameter and 10 mm depth. Measurement of depth of cure by the scraping method was performed according to the ISO 4049 (2009). After placing the specimens, the mold was pressed with polyester strips covered by glass slides and curing was initiated using Bluephase 20i (Ivoclar Vivadent US) light-curing unit through the glass slide. Immediately after curing, the specimens were removed from the mold and the uncured part of the specimens was removed by scraping with a plastic spatula. The absolute length of the hardened composite specimen was measured using a digital vernier caliper. The measured length was divided by two and recorded as the ISO depth of cure.

Results

The depth of cure of the composite specimens was found to be higher for Voco Xtra Fil bulk-fill composite than for Shofu Beautifil bulk-fill composite and Filtek Z350 XT conventional composite (3M/ESPE).

Conclusion

Within the limitations of the study, it can be concluded that the placement of bulk-fill composites with 3-mm increments is mandatory for complete curing.

Clinical significance

Depth of cure of bulk-fill composites determines the adaptation of restoration to the tooth structure, and this study aims to evaluate two newly introduced bulk-fill composites using scrape test.

Authors: Sarıkahya Mustafa , Alaçam Tayfun
Published: March 2021

Aim and objective

This research compares the abilities of the preparation of ProTaper Next (PTN; Dentsply-Maillefer) and XP-endo Shaper (XPS; FKG, Switzerland) files in mesial canals of lower molars with separate binary canals and one foramen with isthmus connection using μCT imaging.

Materials and methods

The comparison showed 20 roots matched according to the similarities in preoperative canal volume, specimen length, and root curvature using preoperative scans, and then they were indiscriminately separated into two groups and prepared either with PTN or XPS instruments. After chemomechanical preparation, the roots were resubmitted to postoperative scans.

Results

There was no variance in instrument systems for the volume of removed dentine, surface area as well as the amount of accumulated debris in the isthmus region (p >0.05). Change in canal surface area and amount of accumulated hard tissue debris (AHTD) was more in the PTN group for total root canal space (p <0.05). PTN instruments increased surface area in a shorter period. Conclusion: Both instrument systems with different design and metallurgic properties had reached the desired volume in different periods; however, neither technique was able to fully prepare the isthmus-containing mesial roots of lower molars.

Authors: Wu Linwan
Published: March 2021

The online environment is filled with uncertain situations. Although digital interface plays an important role in online information processing, limited research has explored whether digital interface could influence how consumers deal with the psychological state of uncertainty in the online environment. The present study focuses on customization as an important feature of digital interface. A lab experiment was conducted to analyze the interplay between psychological uncertainty, interface customization, and the individual trait of uncertainty avoidance on consumers’ online brand evaluation. The results indicated that participants with a strong tendency of uncertainty avoidance evaluated a brand on a customized website more favorably than a non-customized website when they experienced psychological uncertainty. Such effects were not observed among participants with a weak tendency of uncertainty avoidance.

Published: March 2021

The proton conductivity of Nafin 112, 1035, 1135, 115, and 117 membranes has been studied. Measurements were made in 1 M H2SO4 at 298 K using a four-electrode, dc technique. The membrane area resistance increases with thickness, and it was 0.065, 0.092, 0.076, 0.115, and 0.13 Ω. cm2 for Nafin 112, 1035, 1135, 115, and 117 membranes respectively. Th results also showed that the proton conductivity of Nafin 112, 1035, 1135, 115, and 117 membranes was 0.09, 0.11, 0.10, 0.13, and 0.16 S.cm-1 respectively.In the PEM fuel cell applications, it was observed that the optimum Nafin ionomer wt.% requirement does not change with the membrane thickness and the membrane EW. In addition, the Nafin 1035 membrane can remain hydrated for longer than the Nafin 1135, or Nafin 112 membranes because it’s EW is (1000) lower than the Nafin EW of Nafin 1135 (1100), and Nafin 112 (1100). In other words, a higher performance, more stable, and longer life PEM fuel cell can be obtained by using Nafin 1035 membrane as a solid electrolyte especially for high operating temperature.

Authors: Salvador Pinos Carmen , Cárdenas Morales Valheria , Michelena Tupiza Stephanie , Cruz Terán Elízabeth , Romero de Aguinaga Rosa
Published: March 2021

Propósito de la revisión: El objetivo de la revisión es delinear el rol de la Lactancia materna en mujeres con sospecha o diagnóstico de COVID-19. Buscamos reportes en donde se incluye el rol de la microbiota de la leche materna bajo las condiciones de la pandemia de COVID-19.

Recientes Hallazgos: Actualmente existen reportes de detección de anticuerpos contra SARS-CoV en la sangre del cordón umbilical y en la leche materna. La placenta tiene una expresión muy baja de los receptores de la enzima convertidora de angiotensina (ECA2) que parecen limitar la entrada de SARS-CoV-2 al feto.

Extracto: El apego precoz del recién nacido a su madre y la lactancia materna en la primera hora después del nacimiento, al igual que el mantenimiento de la lactancia exclusiva en los primeros 6 meses de vida, garantizan un crecimiento y desarrollo adecuados, así como la protección inmunológica a enfermedades, especialmente respiratorias y digestivas. En el caso de madres con COVID-19, no se ha documentado transmisión vertical de la madre al hijo. No hay evidencia del virus en el líquido amniótico al momento del nacimiento de un bebé ni en la leche materna, por lo que se indica continuar la lactancia, pero cumpliendo rigurosamente las medidas de seguridad e higiene. Adicionalmente, se ha reportado que el tipo de parto y el manejo del mismo podrían estar implicados en el contagio por COVID-19, a través de sangre, heces fecales y otros.

Authors: Jolović Ivana
Published: March 2021

Packaging as a modern instrument of marketing communication can influence consumers' purchase behavior and determine their adherence to certain products. The aim of the research is to determine which elements of product packaging are the most significant in the context of consumer purchasing decisions. At the beginning of August 2020, through an electronic survey questionnaire, empirical research that included 99 respondents was conducted, with the aim of examining the significance of packaging elements from the aspect of the consumer who decides on buying chocolate. An analysis of the content of available foreign and national literature, descriptive method, comparative method, and analysis and synthesis technique, were used for the research purposes. Analysis of the collected data was conducted through the statistical software IBM SPSS Statistics 25.0, which was used for descriptive statistics on data on socio-economic characteristics of respondents, and data on the habits and attitudes of respondents about the purchase; and through the SmartPLS 3.0 software, which was used as a graphical approach to structural equation modeling by the partial least squares technique based on variance (PLS-SEM), in order to analyze the respondents' answers regarding the importance of visual and informational (verbal) elements of packaging. The result of the research is the confirmed assumption that, during the purchase decision making, consumer choice is more influenced by visual than informational (verbal) elements of product packaging.
Business performance management through a prism of software platforms
Authors: Azemović Nedžad
Published: March 2021

In the information age organizations focus on an integrated business process, as opposed to previously specialized functional skills. Globalisation has erased borders, consequently putting firms on the market with the best companies in the world. Considering the development of performance management and the increasingly complex structure and data amount, doing business without the support of information technology (IT) is simply unthinkable. The new paradigm has been known as the third generation of information technology platforms ("3rd Platform IT"). It is based on "cloud", mobile, social and Big Data technologies. This will enable all important digital transformations, evolutions and expansion of the industry in the following period. The future of organisations depends on the ability to master 3rd Platform IT and use them to their advantage. This paper will present some of the software platforms, which concern the strategic management support system, the budget support system, the performance management support system as well as the performance management support systems for teams and individuals.
Management in preschool education
Authors: Aljković-Kadrić Suada , Muratović Amela
Published: March 2021

The issue of management in education has traditionally been subordinated to the analysis of the issue of teaching and upbringing. The history of the teaching profession, in which the school administration has hardly been given importance for a long time, is the history of the school as an institution. To understand complex situations, unpredictable changes in social moments, cultural contexts, to be ready to face the challenges of numerous but often incomplete information, to bring business and the world of education closer is what is expected from management today. Management is like life - a matter of concessions, where the primary task of the manager is to harmonize the near and distant future, the idea at the highest level of abstraction and balancing the forces that are for change and those who are against it.
Inappropriate diet and obesity based on view of the student population
Authors: Simić Pavle , Stanojević Slađana
Published: March 2021

In accordance with their obligations in college, students spend most of their days outside the home. It can lead to irregular and improper diet. The student population tends to consume high-energy, nutrient-poor foods, as well as neglecting meals, usually breakfast. This results in an increasing number of young people who have body-weight problems. The aim of this research was to determine students' attitudes about diet that can lead to obesity, as well as informing students about the consequences of obesity. There were 56 students of the Faculty of Agriculture, University of Belgrade, involved in the study. The research was carried out using anonymous questionnaire. The results of the study showed that a large number of students surveyed considered that they were obese and that obesity was a disease that could be treated in a healthy way. This study suggests that the student population should be offered education in this regard, since most of them are not familiar with the nutritional composition of a food before consuming it, as well as its "body mass index" and "body volume index". On the other hand, the students surveyed are aware of the particular risks that can lead to the onset of obesity, as well as the diseases that can arise as a result of being overweight. In addition, they consider the occurrence of obesity is a major problem not only in the world, but also in Serbia. This research is part of a study entitled "Attitudes and behaviors of students in relation to food and nutrition" and is a form of preventive action to combat the onset of obesity in the student population.
Jo Nesbø's 'Macbeth' and the redefining of understanding the seductiveness of Shakespeare's negative heroes: Hermeneutical and criminological approach
Authors: Ljubinković Marija
Published: March 2021

In an inspirational sense, this study is a derivative of the Hogarth Project - its starting point is the novel Macbeth by the Scandinavian author Jo Nesbø, which in itself redefines Shakespeare's tragedy of the same name, placing it in a contemporary context. The starting point of Nesbø's version is in bringing Shakespeare's thought closer to the modern audience, as well as paying tribute to his genius 400 years after the writer's death. The method of this paper is based on the modernization of interpretation - it is an attempt at interdisciplinary reading (which incorporates approaches characteristic of hermeneutics and criminology) and comparative reading (through the comparison of Shakespeare's plays and Nesbø's novel). In order for such an analysis to be possible in the context of a limited written form, it will be limited to contemplating the notion of the negative hero in Shakespeare's works and Nesbø's novel. The aim of the paper is to interpret the phenomenon of the negative hero and his paradoxical seductiveness, and then to analyse Shakespeare's two protagonists - Richard the Third and Macbeth. Finally, the analysis will be aimed at redefining the phenomenon of the seductiveness of the negative hero done by Jo Nesbø.
The effect of macro factors on bank credit activity in the Republic of Serbia
Authors: Živkov Dejan , Poparić Simo , Ilić Miloš
Published: March 2021

This paper investigates whether and how key macro-fundamentals in Serbia affect the volumes of issued loans of Erste bank to public and business sector in Serbia. We made an effort to determine which particular macro factor has the highest influence on issued credits of Erste bank, and to measure the exact average magnitude of these influences. The main idea is to find out how GDP, inflation, central bank referent interest rate, exchange rate changes and Euribor affect short-term and long-term credit activity of Erste bank in Serbia. The computations are done by applying several multivariate regression models in which dependant variables are the volume of issued credits towards civil sector and enterprises. Based on the results, we can report that Euribor is the most important factor of all scrutinized macro-aggregates, since it affects most of the analysed bank loans. Besides Euribor, we find that other macro fundamentals influence the issued loans only sporadically. In other words, the level of GDP and inflation affect only long-term loans for businesses, while referent interest rate influences only short-term loans for public. We find that exchange rate changes have no effect on any loan of Erste bank, whatsoever, which clearly indicates that the bank protects itself very successfully against this type of macro risk.

Let G = (V,E), V = {v1, v2,..., vn}, be a simple connected graph of order n, size m with vertex degree sequence ∆ = d1 ≥ d2 ≥ ··· ≥ dn = d > 0, di = d(vi). Denote by G a complement of G. If vertices vi and v j are adjacent in G, we write i ~ j, otherwise we write i j. The general zeroth-order Randic coindex of ' G is defined as 0Ra(G) = ∑i j (d a-1 i + d a-1 j ) = ∑ n i=1 (n-1-di)d a-1 i , where a is an arbitrary real number. Similarly, general zerothorder Randic coindex of ' G is defined as 0Ra(G) = ∑ n i=1 di(n-1-di) a-1 . New lower bounds for 0Ra(G) and 0Ra(G) are obtained. A case when G has a tree structure is also covered.

Published: March 2021

The paper deals with the poetic features of Zaim Azemović (1935 - 2015) i Faiz Softić (1958), the contemporary Sandžak poets, writers, publicists, essayists, critiques and researchers of folklore who have given the original poetic discourse to Sandzak-Bosniak and the entire Bosniak literature with their works, whereby enriching these literary traditions with new thematic-motive material and peculiar language expression. Zaim and Faiz shaped their artistic worlds with classic methodological acts, but also with modernistic literary and artistic techniques. Using the interpretative approach, in this paper we comparatively observe their most significant poetic accomplishments, basing the research on the hypothesis that identity mark significantly influenced the poetics of these two notable Sandžak poets. The richness and diversity of the opus of these two Sandžak and Bosniak poets, visible influences they left and are leaving on the contemporary literary messengers, and the esthetic qualities of their creativity, are the main incentive for choosing the authors and the corpus of works that are the subject of our research.
Tag Z boson jets via convolutional neural networks
Authors: Li Jing , Sun Hao ,   School of Physics, Dalian University of Technology, Dalian 116024, China
Published: March 2021

The jet tagging task in high-energy physics is to distinguish signals of interest from the background, which is of great importance for the discovery of new particles, or new processes, at the large hadron collider. The energy deposition generated in the calorimeter can be seen as a kind of picture. Based on this notion, tagging jets initiated by different processes becomes a classic image classification task in the computer vision field. We use jet images as the input built on high dimensional low-level information, energy-momentum four-vectors, to explore the potential of convolutional neural networks (CNNs). Four models of different depths are designed to make the best underlying useful features of jet images. Traditional multivariable method, boosted decision tree (BDT), is used as a baseline to determine the performance of networks. We introduce four observable quantities into BDTs: the mass, transverse momenta of fat jets, the distance between the leading and subleading jets, and N-subjettiness. Different tree numbers are adopted to build three kinds of BDTs, which is intended to have variable classifying abilities. After training and testing, the results show that the CNN 3 is the neatest and most efficient network under the design of stacking convolutional layers. Deepening the model could improve the performance to a certain extent but it is unable to work all the time. The performances of all BDTs are almost the same, which is possibly due to a small number of input observable types. The performance metrics show that the CNNs outperform the BDTs: the background rejection efficiency increases up to 150% at 50% signal efficiency. Besides, after inspecting the best and the worst samples, we conclude the characteristics of jets initiated by different processes: jets obtained by Z boson decays tend to concentrate in the center of jet images or have a clear differentiable substructure; the substructures of jets from general quantum chromodynamics processes have more random forms and not only just have two subjets. As the final step, the confusion matrix of the CNN 3 indicate that it comes to be kind of conservative. Exploring the way of keeping the balance between conservative and radical is our goal in the future work.
An In-vitro Study to Determine the Sealing Ability of Biodentine when used as a Class II Restorative Material
Authors: Choudhary Deebah
Published: March 2021

Introduction: Microleakage is a major setback to restorative dentistry. Leakage at the tooth/restoration interface may lead to numerous problems like postoperative sensitivity, recurrent caries, marginal sealing and later total failure of restoration. Aim: To determine the sealing ability (microleakage) of a new hydraulic calcium silicate cement (Biodentine) as a base material and a bulk filling material. Materials and Methods: An in-vitro study was conducted with ten freshly extracted maxillary molars from March 2019 to June 2019. Standardised Class II cavities were prepared on mesial and distal proximal surfaces. The twenty prepared samples were randomly divided into two groups (n=10)- G1 (BiodentineTM group) and G2 (BiodentineTM + Tetric N-Ceram group). The samples were subjected to thermocycling, followed by 1% methylene blue dye immersion. They were subsequently sectioned both buccolingually and mesiodistally in order to separate to proximal restorations (mesial and distal) and appreciate the amount of dye penetration at tooth/restoration interface respectively. Microleakage was evaluated by observing the samples under a stereomicroscope (30x). The data obtained was analysed using one-way ANOVA test and compared using Post-hoc test. p-value <0.05 to be considered significant. Results: Biodentine showed no significant difference between the sealing ability as a bulk filling and a base material. Group G2 (0.35) indicated comparatively less microleakage as compared to Group G1 (0.6) but the difference in microleakages in both groups was insignificant (p-value 0.083467). Conclusion: BiodentineTM exhibits microleakage when used as a bulk filling material and as a dentin substitute in Class II cavities since there is no significant difference in both the groups.

Published: March 2021

Introduction: Enamel demineralisation is often seen in patients undergoing fixed orthodontic treatment because appliances create retentive areas around the brackets leading to food debris accumulation. The method of ligation is also an additional factor in causing plaque accumulation leading to demineralisation around the brackets. Aim: The present study aims to compare enamel demineralisation around self-ligation brackets and conventional ligation brackets at the 3rd month and 12th month of orthodontic treatment using laser fluorescence. Materials and Methods: The present prospective study aims to compare enamel demineralisation around self-ligation brackets (Damon 3mx) and conventional ligation brackets (Gemini 3M) at the 3rd month and 12th month of orthodontic treatment using laser fluorescence. Nineteen subjects who were scheduled for fixed orthodontic treatment were selected for the study and were divided into two groups that is conventional ligation and passive self-ligation. Diagnodent (DD) was used to take enamel demineralisation scores at the time of bonding (T0), 3 months (T1) and 12 months (T2) into treatment. All statistical analysis was performed using IBM SPSS version 20. Chi-square test was performed to find the gender association, One-way ANOVA test was carried out to evaluate the difference of DD scores at time period T0, T1 and T2 in self-ligation group and conventional ligation group and Independent t-test was carried out to evaluate the difference of DD scores between self-ligation brackets and conventional ligation at T0, T1 and T2. Results: One-way ANOVA test reported that in conventional ligation groups there was a statistically significant difference in the mean DD scores between T0 and T1, T0 and T2 (p<0.05). Similarly, in the self-ligation group, a statistically significant difference was observed in the mean DD score between T0 and T1, T0 and T2 (p<0.05). Independent t-test to evaluate the difference of mean DD scores between self-ligation brackets and conventional ligation at T2 was found to be statistically non-significant (p>0.05). No gender association was noted. Conclusion: The method of ligation did not influence enamel demineralisation around orthodontic brackets.
Multidisciplinary Approach to Prosthetic Rehabilitation of Traumatically Lost Mandibular Anterior Teeth using Onlay Graft, Laser and Dental Implants: A Case Report
Authors: Mallick Rizwana , Faisal Mohammad , Sawai Madhuri Alankar , Jain Vanshika
Published: March 2021

Traumatic injuries are a primary cause of anterior tooth loss and associated soft and hard tissues damage. Management of lost teeth necessitates a multidisciplinary approach. While the simplest approach in such cases remains that of a Removable Partial Denture (RPD), problems with support and retention can often lead to functional limitations and patient discomfort. Further, patients generally prefer to have a fixed solution over a removable prosthesis. Conventional bridgework also does not provide with suitable replacement in patients with large edentulous spans, thereby, leaving dental implants as the only predictable rehabilitation option. Dental implants present with their own limitations in terms of need for sufficient bone volume for optimum biomechanical foundation for implant placement, adequate space between present teeth and vestibule depth to avoid impingement of the placed implant. This present report illustrates a case of 24-year-old male patient who experienced Road Traffic Accident (RTA) leading to multiple injuries and loss of permanent mandibular anterior teeth. Being dissatisfied with his current removable prosthesis, implant-based treatment was planned. Various clinical findings indicated towards need for onlay grafting and laser assisted periodontal surgery. Thus, a staged multidisciplinary approach was adopted. Postoperative clinical and radiographic findings showed clinically successful treatment. The patient too was satisfied with prosthesis functionality and achieved aesthetics.
Dryland Farmers on Climate Resilient Practices – An Adoption Study at an Industrialized Taluk of Tamil Nadu
Authors: Niranjan D. Alagu , Bose Dipak Kumar
Published: March 2021

Aims: To study the adoption of climate resilient practices by the farmers in the dryland region.

Study Design: Cross-sectional survey design was used for the present descriptive study.

Place and Duration of Study: The study was conducted in Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad (Prayagraj) during the year of 2018 and for the period of 6 months.

Methodology: The study used direct interview method with the subjects using a structured and pre-tested interview schedule for primary data collection in the sampled area which is an industrialized taluk of Tamil Nadu. The selection of area was purposeful, whereas, selection of villages was random and 15 respondents form each village was convenient. The collected data was tabulated and interpreted using descriptive statistics and correlation analysis.

Results: The results of the study suggest that there is a poor adoption level of climate resilient practices existing among the dryland farmers. While, some of the practices like incorporation of residues in to soil instead of burning, brown and green manuring, conservation tillage, temperature tolerant varieties, farm machinery custom hiring centre, location specific intercropping systems, crop rotation, usage of better planting materials, prophylaxis, custom hiring centre and weather based insurance were adopted to some extent. Though there was no specific intervention to sensitize on these practices, adoption of above mentioned practices were found which could be due to the passive adaptation by the farmers of the locality over years. And the results of correlation analysis revealed that there is a significant relationship between adoption of climate resilient practices and variables like the respondents’ education, exposure to mass media exposure, contacts with extension agents, innovativeness level, risk orientation and scientific orientation at 0.01% level of significance.

Conclusion: The results of the study will definitely help in evaluating government projects (as baseline) like National Initiative on Climate Resilient Agriculture, and strengthening programme planning and implementation in climate change.
Universal Health Coverage- A Case Study of Indian Healthcare System during COVID-19 Pandemic
Authors: Nandwani Rashika
Published: March 2021

Aim: The main purpose of this paper is to look at the Indian healthcare system during the COVID-19 pandemic and how COVID-19 acts as barrier and also presents some opportunities towards the road of Universal Health Coverage (UHC).

Background: COVID-19 has exposed the vulnerability of health systems across the world and India is no exception. The World Health Organization (WHO) has kept the definition of UHC very flexible and has left on the country which is implementing it as to how much of the population and which services should be included in the scheme. 

Discussion: India already has a unique flagship program Ayushman Bharat where it is trying to cover her most vulnerable population against catastrophic expenditure of health. This paper further investigates the progress of India towards UHC and how COVID-19 is acting as an impediment for India to progress towards it. On the other hand, it also poses some opportunities which had not been explored in the past. Health Systems Strengthening is the path towards the achievement of UHC and due to COVID-19, India has touched upon all the six building blocks which are needed to strengthen our system towards the achievement of UHC.

Recommendations and Conclusion: It recommends that Indian system should be more proactive than reactive; it also suggests following a systems-based approach and to not target the problem in silos. It also suggests increasing the government funding as well as establishment of proper public health cadre. To conclude, this paper also suggests that the government should include outpatient expenses into their scheme, and they should also concentrate towards building adequate infrastructure in order to face future pandemics like COVID-19.
