Authors: Wang Anbang , Guo Lihong , Chen Yuan , Wang Junjie , Liu Luo , Song Yuanzhang
Published: June 2022

The travelling salesman problem (TSP) is an NP-hard problem in combinatorial optimization. It has assumed significance in operations research and theoretical computer science. The problem was first formulated in 1930 and since then, has been one of the most extensively studied problems in optimization. In fact, it is used as a benchmark for many optimization methods. This paper represents a new method to addressing TSP using an improved version of cuckoo search (CS) with Stud (SCS) crossover operator. In SCS method, similar to genetic operators used in various metaheuristic algorithms, a Stud crossover operator that is originated from classical Stud genetic algorithm, is introduced into the CS with the aim of improving its effectiveness and reliability while dealing with TSP. Various test functions had been used to test this approach, and used subsequently to find the shortest path for Chinese TSP (CTSP). Experimental results presented clearly demonstrates SCS as a viable and attractive addition to the portfolio of swarm intelligence techniques.

The functionalization of polyester fabric (PES) with antimicrobial agents presents huge number of potential applications in advanced products. However, the lack of functional groups and the high PES hydrophobicity make the functionalization processes costly, prolonged and requires the use of polluting chemicals compounds. In this work, dielectric barrier discharge (DBD) plasma treatment, an affordable and environmental-friendly method, was used to introduce new chemical groups, increase the surface energy and roughness of PES in order to improve the adhesion of silver nanoparticles (AgNPs) in its surface. The PES functionalization was evaluated by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and antimicrobial efficacy against Staphylococcus aureus and Escherichia coli. Despite some additional oxidation, the DBD plasma-treated PES showed superior adhesion of AgNPs and excellent antimicrobial efficacy even after 10 washing cycles (WC).

Authors: Xia Gang , Xin John H.
Published: June 2022

As global warming continues, functional textiles with moisture/thermal management performance are becoming more and more important. In this paper, a cationic hydrophilic polymer (CHIP) was developed, and combined with flexible and simple coating methods to achieve durable moisture/thermal management of polyester fabrics. The as-prepared fabrics exhibit excellent washing fastness, the wettability of the coated fabrics can withstand 150 home laundry cycles. Owing to its firm fixation, the methods of single-side spraying and templated-spraying were adopted to achieve water/sweat unilateral penetration or directional transport through polyester fabrics, which realizes the timely and directionally transport of sweat as well as thermal in fabrics. This work is useful for design of high-performance moisture/thermal management fabrics for various applications, e.g., quick-dry sportswear, outdoor uniforms, and other functional garments.

Authors: Friese Danny , Hahn Lars , Cherif Chokri
Published: June 2022

A significant strategy to reduce the demand for natural resources and the associated environmental impact is enhanced material efficiency in the design process for new building structures. Innovative concepts for designing, modelling, constructing, producing and utilising sustainable resource-efficient concrete-based building components will be the foundation for future-oriented constructions. For this reason, the ability to process biologically inspired 3D textile reinforcement structures is crucial to fully exploit the potential of carbon concrete. This research project provides a fundamentally realigned, CAE-supported approach so that optimization algorithms, numerical models for the generation of robot placement paths and bionically induced yarn positioning can be taken into account. The evolved intelligent and modular yarn placement system forms the basis to overcome current challenges involved in the placing and stabilizing of spatial and highly branched reinforcement topologies during the manufacturing process. Hence, the novel tool-independent, geometrically highly variable, robot-supported fibre placement technology is supposed to be capable of manufacturing biologically inspired load adapted 3D textile topologies with reinforcement in z-direction.

Published: June 2022

Given an integer

g \geq 0

and a weight vector

w \in \mathbb{Q}^n \cap (0, 1]^n

satisfying

2g - 2 +\sum w_i > 0

, let

\Delta_{g, w}

denote the moduli space of

n

-marked,

w

-stable tropical curves of genus

g

and volume one. We calculate the automorphism group

\operatorname{Aut}(\Delta_{g, w})

for

g \geq 1

and arbitrary

w

, and we calculate the group

\operatorname{Aut}(\Delta_{0, w})

when

w

is heavy/light. In both of these cases, we show that

\operatorname{Aut}(\Delta_{g, w}) \cong \operatorname{Aut}(K_w)

, where

K_w

is the abstract simplicial complex on

\{1, \ldots, n\}

whose faces are subsets with

w

-weight at most 1. We show that these groups are precisely the finite direct products of symmetric groups. The space

\Delta_{g, w}

may also be identified with the dual complex of the divisor of singular curves in the algebraic Hassett space

\overline{\mathcal{M}}_{g, w}

. Following the work of Massarenti and Mella (2017) on the biregular automorphism group

\operatorname{Aut}(\overline{\mathcal{M}}_{g, w})

, we show that

\operatorname{Aut}(\Delta_{g, w})

is naturally identified with the subgroup of automorphisms which preserve the divisor of singular curves.
Modelling effectiveness of PPE on aerosol exposure for healthcare workers during typical ENT procedures
Authors: Senior B.A. , Schlosser R.J. , Lesch Jr. P.R.
Published: June 2022

Background: Previous studies report environmental aerosolization with various endonasal procedures, but do not specifically measure intranasal levels of inhaled aerosolized particles in healthcare providers (HCP) performing such procedures. The purpose of this study is to measure the impact of various types of personal protective equipment (PPE) worn by HCP during a variety of office-based endonasal procedures. Methodology: Simulated sneeze and office-based procedures were performed in a test model and aerosol levels were quantified in the middle meatus of a simulated HCP model wearing various forms of PPE by using a laser diode-based particle counter. Endoscopic exam, balloon sinus dilation, suction and irrigation, simulated tissue resection with a microdebrider, and routine debridement procedures were evaluated. The aerosol levels were evaluated with and without the use of PPE to assess HCP aerosol exposure. Results: A simulated sneeze represents a worst-case aerosol generating event when compared to other common office-based procedures (approximately 1,000 times greater than baseline particle count). Common endoscopic procedures did not generate significantly greater particle counts above baseline. When compared to no mask, a surgical mask reduces particle counts experienced by HCP in the middle meatus by 69%, while an N95 mask significantly reduced particles by 93%. Conclusions: The levels of aerosols generated during common office-based procedures are consistent with the background aerosol levels measured at baseline. Masks are effective, with the N95 mask most effective at reducing HCP exposure to aerosols generated during a simulated sneeze.

Authors: Dakić Stojanka , Brcanov Dejan
Published: June 2022

The global pandemic caused by the Covid-19 virus has affected the economy of every country in the world without exception. The aim of this paper is to analyze the impact of the Covid-19 crisis on the Serbian labor market. Periods of complete closure, changes in the way of doing business, restrictions on working hours, as well as online work have affected both supply and demand in the Serbian labor market. At the beginning of the crisis, the biggest consequences were suffered by employers and employees in the catering, tourism, transport and personal services sectors (so-called high-contact activities). The decline in employment and income in these areas has led to a decline in demand for products and services from sectors that belong to the so-called low-contact activities, which spread the crisis to the entire economy and caused the deterioration of the economic and social position of the population. The paper presents key indicators of the Serbian labor market before and during the Covid-19 crisis in order to point out the seriousness of its consequences and create a basis for future research on the development of the sectors most affected by the Covid-19 crisis.

Published: June 2022

Modern conditions characterized by the fourth industrial revolution emphasized the crucial role of intangible assets in the success of companies. Tangible and intangible assets of companies within cities make a significant part of the development of competitive knowledge-based cities. However, development trends in recent decades have shifted the focus from tangible assets to intangible assets such as knowledge, innovation and intellectual property. In modern conditions, intangible assets are becoming an important strategic resource necessary for the improvement of the competitive advantage of companies within any industry. There is evidence of the influence of intangible assets on improving company performance and creating corporate value. The development of the knowledge-based economy has additionally encouraged companies to efficiently use soft capital such as human capital and knowledge since economic development in modern conditions is driven by soft capital. Therefore, the aim of this paper is to evaluate the efficiency of intangible asset management within the high-tech industry companies of ten European cities (Amsterdam, Barcelona, Berlin, Brussels, Dublin, Lisbon, London, Oslo, Paris and Zurich). The sample consists of data for 2775 high-tech companies within stated cities related to the number of patents, the number of trademarks, annual fixed asset growth rate, annual intangible asset growth rate, share of intangible asset in total asset, annual current asset growth rate and current ratio for the last year available in the Amadeus database. Efficiency evaluation was performed by creating a composite index using the Benefit of Doubt approach. The results of the efficiency analysis indicate that a large part of the companies in the sample achieves relatively low levels of efficiency. Differences in average efficiency between companies in the analysed cities were assessed using one-way ANOVA. The results indicate that the average efficiency of high-tech companies operating in Dublin is significantly better than the average efficiency of high-tech companies in other analysed European cities. In addition, high-tech companies operating in Berlin are, on average, more efficient than high-tech companies operating in Paris and London. There are no statistically significant differences between the average efficiencies of high-tech companies in other analysed European cities.

Published: June 2022

During the last two decades the alignment of business and IT progressively occupies the attention of companies and is frequently stated as the key question and a challenge for the improvement of business and achieving success. In the beginning they were observed mainly as a support in administering the tasks and conducting defined business strategy, nevertheless, with daily development of new and improvement of the existing technologies, their impact was constantly increasing. Nowadays, they commonly represent the driving force of change in organizations and the aspect which has a significant influence on conceiving the business strategy itself. The relevant research is chiefly focused on advantages, challenges and models for achieving the IT business alignment. Conversely, they neglect the details of specific technologies that lead to changes and the need to harmonize business strategy and organizational infrastructure and processes on the one hand and IT strategy and IT infrastructure and processes on the other. A small number of papers talk about the application of certain technology and its effects on the business of companies. Therefore, the aim of this paper is to, through the overview of relevant literature, determine and make conclusions about how the utilization of new technologies influences the change and alignment of business and IT in companies. Technologies whose effects will be in focus of this research are: Big data; Internet of Things (IoT) and Blockchain.

New discoveries in the field of technology have created a space between the ways in which organizations function and the potential ways in which they function. Recent events have accelerated the need to solve the given problem. All this opens new possibilities in the fields of information systems and digital transformation. With the progress and change in the way the organization functions, there are new requirements in the mentioned areas, but also in the area of ??the staff itself. Chief Digital Officer - CDO (Chief Digital Information Officer - CDIO), a newer position, and Chief Information Officer - CIO are one of the key positions in information technology and digital transformation of the organization. The subject of the research is the analysis of the given roles, their potential inconsistencies, as well as their connection with the information system. Based on the identified works, a systematic review of the literature was performed. The research found that the CDO is more responsible for converting the "traditional" way of doing business into the digital way of doing business, while the CIO is more responsible for the implementation in the field of information technology. Some organizations prefer to expand the activities of the CIO in exchange for hiring a CDO. The field of work research can be a potential topic for further research due to the topicality of the topic itself, as well as the process of digital transformation in which we are currently.

Authors: Marković Ivana , Rabasović Biljana , Janković Perić Marina
Published: June 2022

Social media is playing an increasingly important role in many aspects of tourism. While planning a trip, tourists look for information on social media, consider the comments of users who have already visited the destination, and share their experiences about the destination during and after the holiday. Therefore, social media has been proven as an excellent channel for promotion and communication with tourists, as well as an effective complaint management system. This topic has been the subject of many studies that explored the role of social media in promoting, building the image and brand of a tourist destination, while few studies have explored the impact of social media on tourist destination choice. Therefore, the subject of this paper is to analyze the influence of social media on choosing the tourist destination. The aim of this paper is to examine the impact of the availability of information related to the destination and user-generated content through social media on the tourist destination choice. Data were collected using the online survey technique, and research hypotheses were tested by regression analysis. The study results indicated the importance of the availability of information about the destination and a word-of-mouth propaganda on social media while choosing a destination. The theoretical contribution is reflected in new information regarding the role of social media in tourism, which is limited in the domestic scientific literature. As a practical contribution, the study provides information that may be useful to tourism service providers in creating a promotional campaign on the Internet.

Authors: Jovanoska Dijana , Mancheski Gjorgji
Published: June 2022

The phenomenon called Big Data today is one of the most significant and least visible consequences of the development of technology and the Internet. Namely, the data generated by today's globally connected world is growing at an exponential rate and they are a real "gold mine" for those users who know how to correctly interpret such data and make successful decisions based on them. Data analysis and processing is one of the most important components of a large data system, and in this branch of data science the most popular is the Python programming language, which provides its users with a large number of constantly maintained program libraries and developing environments. The most important thing for legal entities and individuals is that almost all program libraries and functions provided by this programming language come with free licenses and possess open code, maintained and quality technical documentation, which provides each company with significant money savings and time. This research paper is dedicated to the possibility of determining and creating a multi regression model of large amounts of data by using Python, on the basis of large amounts of data provided by two market retailers in order to display a multi regression model and assess its predictive power. Because the number of variables is large, several models have been made in this research paper and a comparative analysis of the different models has been made, which shows that Python is a good tool that can be used repeatedly to select different variants and evaluate the resulting model for which a graphical interface can be made and would be much more acceptable as an end user, can be placed on a server on the Internet or on a modern Cloud platform and used by users as an on-demand concept and the results can be embedded in end-user interfaces and models made in this way (with dynamic data extraction)can be used in BI and machine learning processes.
The Roles of Strategic Alliances, Innovation Capability, and Cost Reduction Towards Customer Loyalty and Firm's Competitive Advantage
Authors: Musa Soebowo
Published: June 2022

Disruptive business environment such as the Covid-19 pandemic and the recent high volatility in commodity prices has changed the way businesses were conducted. The heavy equipment industry is one of many industries affected by such a disruptive environment, especially those who are related to the mining industry where the volatility of the commodity prices has a significant impact on their business performance. Alliances are commonly formed by heavy equipment distributors and their customers to create a mutual benefit to sustain their performance. Strategic alliances have attracted substantial attention from industry as well as academia as a way to stay competitive. Most strategic alliances focus on the strategic alliances partner-to-partner in serving their customers. Consumer behaviour has changed due to disruptive forces that make firms' strategic focus more on human-centric business approaches. This study looks at the roles of strategic alliances in the partner-to-customer relationship, innovation capability, and cost reduction toward customer loyalty and competitive advantage. Data was collected from 335 respondents from the firms that have entered into strategic alliances. This study finds strategic alliances have the highest association with cost reduction, followed by their association with innovation capability. Strategic alliances enhance customer loyalty through innovation capability. Cost reduction is not a lever to develop customer loyalty in the strategic alliance partner-to-customer relationship. The study also confirms that operational efficiencies are necessarily the source of competitive advantage, but strategic alliances are.
New Common Agricultural Policy of the European Union (2023-27) and Potential Implications on Serbian Agriculture
Authors: Vodana Jović Luna , Đokić Danilo , Zekić Stanislav
Published: June 2022

In the last few years, significant changes have taken place in the agricultural policy of the European Union. First, in 2020, the Farm to Fork Strategy was presented as part of the broader European Green Deal strategy adopted a year earlier. The main idea of ??this strategy is to redesign the European food system, which has a significant impact on global climate change. It is estimated that almost one-third of global greenhouse gas emissions come from agri-food systems. In addition, these systems use vast amounts of natural resources (primarily water and land), resulting in biodiversity loss. This strategy has contributed to redefining the European Union's Common Agrarian Policy for the period from 2023 to 2027. The Agreement on the Reform of the Common Agrarian Policy was officially adopted on December 2, 2021. One of the critical elements of this agreement is the protection of the environment and the idea of ??making the European Union's agricultural policy "greener". Thus, a strong interdependence between the agricultural policy and the European Green Agreement has been created. On the other hand, Serbia is in the process of European integration, which includes harmonization with the Common Agricultural Policy. Therefore, the new reform of the Common Agricultural Policy and the Farm to Fork Strategy could be significant for the development of the agricultural policy of Serbia with substantial consequences for the agri-food sector. This paper aims to present new trends in European policy in the food sector and point out the potential implications for the agricultural sector of Serbia.

Authors: Angeloska-Dichovska Monika , Boshkoska Meri , Angeleski Marjan
Published: June 2022

Small and medium-sized enterprises (SMEs) are crucial for any national economy through their vital contribution to sustainable growth, economic development and employment. The digital revolution, globalization, and the latest impact and pressure caused by the Covid-19 pandemic have posed even greater barriers and challenges for these enterprises. In order for small and medium-sized enterprises to respond to the new challenges, to participate in the market and gain a competitive position, they need to be different, and this can only be accomplished through an innovative way of working. To foster innovation, strategic changes are needed in the operation of the SMEs, with a focus on the people involved, the ways and methods used in the organizational environment, and the desired innovation results. Connecting to the external environment (networking) and/or using an open innovation system are also fundamental to the success of the enterprise innovation process. Innovative capacity of the businesses is a function of the organization’s culture, resources and networks. The main purpose of this paper is to identify certain strategic factors that contribute to creating an innovative organizational environment and fostering innovation, i.e. increasing the innovation capacity of SMEs in Pelagonia region in North Macedonia.

Authors: Đorđević Biljana , Ivanović-Đukić Maja , Lepojević Vinko , Milanović Sandra
Published: June 2022

The COVID-19 pandemic has brought significant changes in all segments of the functioning of human society and has particularly affected the way companies organize their business. As its appearance at the same time meant a high health and safety risk in the sphere of work, the corporate social responsibility (CSR) towards all stakeholders, and especially employees, deserves special attention. Employees are naturally most interested in the management of the company treating them in an ethical and responsible way, but they are also very interested in responsible behaviour towards other stakeholders. As the performance of the company largely depends on the attitudes and behaviour of the employees, it is very important to examine how the employees evaluate the entire CSR. Based on the above, the focus of this paper will be to examine the impact of CSR in the context of the COVID-19 pandemic on job satisfaction (JS) of employees, as well as their eventual turnover intention (TI). In this regard, during 2021, an empirical study was conducted using the case study method by surveying 100 employees in the Republic of Serbia. By testing the mediating effect of JS between CSR and TI, it was concluded that CSR is a positive predictor of JS and that JS is a mediating variable between CSR and TI. The results of the analysis have a theoretical and practical contribution in the field of human resource management because they provide insight into possible predictors of JS and TI.

Actualmente los medios están bombardeando a la sociedad con contenido sumamente violento y sexualizado por medio de la música, series de televisión o plataformas digitales, así como los videojuegos más famosos cuyo objetivo principal es el de “matar” a los oponentes, está comprobado que inconscientemente el estar en permanente contacto con este tipo de contenido puede llegar a influir, afectar conductas o presentarse problemas de aprendizaje en los estudiantes.
Por lo que la creación de estrategias, el trabajo de concientización y sobre todo la formación de personas críticas capaces de saber decidir el tipo de contenido apropiado y saber hacer uso de todas las herramientas como apoyo en la educación es sumamente importante para poder así lograr un cambio no solo en nuestros niños y adolescentes, sino en toda la sociedad actual y crear un mejor futuro con ciudadanos conocedores de las tecnologías pero complementados con valores y sensibles al dolor humano.

This paper will discuss parametric optimization of the
turning process using the Taguchi method in order to improve the
quality of manufactured goods, as well as engineering design
development for studying variation Turning of Al7129 metal
matrix reinforced with Titanium carbide (TiC) and Boron carbide
(B4C) powder. Metal Matrix Composite with Carbide tool for
carrying out experiment to optimize material removal rate and
surface roughness.
There are three machining parameters i.e., spindle speed, feed rate
and depth of cut. Different experiments are done by varying one
parameter and keeping other two fixed so that optimised value of
each parameter can be obtained. In this project dry turning of
Al7129 as a work piece and carbide insert tool. The range of
cutting parameters are cutting speed (180, 350 and 500 m/min),
feed rate (25, 80 and 125 mm/rev), depth of cut (0.2, 0.6 and 1
mm). Taguchi orthogonal array is designed with three levels of
turning parameters with the help of software Minitab version 16.
Taguchi method stresses the importance of studying the response
variation using the signal to noise (S/N) ratio, resulting in
minimization of quality characteristic variation due to
uncontrolled parameters. It is predicted that Taguchi method is a
good method for optimization of various machining parameters as
it reduces number of experiments. A confirmatory test confirms
the results, which indicate the optimum values of the input
factors.

The world faces major environmental challenges
associated with waste generation and waste collection ,
transport, treatment and disposal, by increase in population,
volume of waste generation is also increased, this impacts on
the environment and public health. Even the private areas
which are clean enough failed to utilize the resources
efficiently. This waste management system includes
segregation of waste into different parts at the local area itself
and which are further used as raw material for different
process such as power generation, recycling etc. Also it creates
clean, hygienic and advanced waste damping area. The
generated power can be utilized for domestic and commercial
purpose.

Published: June 2022

Este relato de pesquisa se baseia em textos produzidos por estudantes da licenciatura em Ciências Sociais da Universidade Federal da Paraíba (UFPB) acerca de suas trajetórias escolares. A pesquisa foi feita no âmbito da disciplina “Educação e Sociedade no Brasil” em parceria com projetos de monitoria. Fragmentos desses textos foram selecionados, destacando experiências positivas e negativas, expectativas, dificuldades e estratégias significativas da/na vida estudantil. Privilegiamos especialmente relatos sobre racismo, questões de gênero e a importância de políticas públicas educacionais, tais como cotas de ação afirmativa, bolsas de estudo e auxílios estudantis. Entretanto, é importante enfatizar que não se tratou de identificar um perfil estudantil. Algumas experiências mostraram-se mais comuns, outras mais pontuais. Ao reuni-las neste relato, nosso objetivo foi conhecer um pouco melhor a trajetória desses/dessas estudantes, buscando reconhecer potenciais que podem ser mais bem explorados e fragilidades que devem ser mais bem cuidadas por parte do corpo docente e da UFPB de maneira mais geral.
