Authors: Lacerda Maicon , De Matos Katherine Helena Oliveira , Silveira Ismar Henriques
Published: July 2021

O modelo de avaliação do desempenho da gestão do setor portuário denominado de GESPORTOS surgiu da necessidade de se conceber uma ferramenta, capaz de avaliar o nível de maturidade da gestão, a partir de características específicas do setor portuário, embasada em critérios reconhecidos e aceitos como o “estado da arte” da gestão. Este trabalho objetivou estruturar uma avaliação do desempenho da gestão direcionada ao setor portuário, considerando as suas especificidades, embasada em fundamentos reconhecidos e aceitos por organizações de classe mundial. Adotaram-se, como base do modelo, os mesmos fundamentos estabelecidos pela Fundação Nacional da Qualidade (FNQ) para o Prêmio Nacional da Qualidade (PNQ), entendendo-se estes, como referências universais e aplicáveis a qualquer tipo de organização, independente do seu negócio, porte e características específicas, permitindo assim a comparação com outras organizações de “classe mundial”. Ao adotar os mesmos fundamentos do Modelo de Excelência, assumiu-se que estes são os pilares de sustentação das organizações que buscam a excelência na gestão como essência da sua competitividade, porém percebeu-se a necessidade de uma adaptação dos critérios em função das particularidades do setor, que apresenta características únicas em relação a outros segmentos econômicos. Os resultados obtidos neste trabalho são úteis para a tomada de decisão, melhoria da gestão e aumento da competitividade deste importante segmento.

Published: July 2021

O presente artigo é um estudo de caso que tem por objetivo analisar a adequação da produção de serviços terceirizados de uma pequena empresa do ramo de confecção de vestuário situada na cidade de Guabiruba - SC, que faz parte de um segmento intitulado de prestadora de serviços de costura de artigos de malha de linha básica. Os dados foram pesquisados de forma qualitativa com aplicação de um questionário previamente elaborado pelos autores e respondido pelo socioproprietário da fábrica que aqui denominamos de Confecções Cavichioli. O contato foi realizado de forma pessoal, obtendo-se informações a respeito do histórico de demanda dos últimos dois anos, capacidade produtiva, fluxo de produção, layout e uso de célula de confecção. A partir das propostas de Tubino (2009), Slack et al. (2002), Toledo (1992) entre outros citados neste artigo, foi possível confrontar a literatura com as práticas da cadeia produtiva investigada. Identificou-se que a previsão de demanda, baseada na capacidade produtiva da empresa, mostrou-se mais eficiente do que aquela relacionada ao histórico de produção e que a modificação do layout do maquinário, junto com a alteração para um sistema produtivo em célula e por batelada, apresentou o melhor resultado para o atendimento da demanda exigida pelo mercado.

Globally, the youth population aged between 10 and 24 years is the fastest growing and faces health and nutritional challenges affecting their growth and development, livelihoods and future careers. The government needs to take necessary action towards the full realisation of the right to health, water, education and adequate standards of living, amongst others. A cross-sectional descriptive study using a mixed method approach was conducted. The study aimed at gaining an insight into perceptions about underlying factors, having an impact on the realisation of the Right to Food (RtF)of adolescents in the Sterkspruit area of the Senqu sub-district (Eastern Cape Province). It, furthermore, explored possible solutions and opportunities to facilitate the progressive realisation of the RtF for adolescents in this area. In-depth interviews were held with eight (8) key informants who were actively involved in the community. Fifty (50) adolescents aged 10 to 19 years completed a self-administered questionnaire and participated in Focus Group Discussions, stratified for gender and age. Through content analysis of qualitative data, transcripts were coded and emerging themes were grouped, using the ATLAS.ti 7 text analysis programme. Sixteen (16) percent of the adolescents sometimes had access to only one food source at home and have experienced hunger at times. The most pressing issues identified by participants, which compromises the realisation of adolescents’ right to food and health, was hunger caused by a combination of a monotonous diet, lack of agrarian resources, unemployment and mismanagement of Child Support Grants. Although government was regarded as the main duty-bearer responsible for the realisation of the RtF, it was perceived to be inefficient in taking sustainable measures to enhance food security in this resource-poor area. Very few participants identified adolescents’ own responsibility as rights-holders. The implementation of a human rights-based approach is needed for both the duty-bearers and rights-holders to facilitate adolescents’ physical and economic access to sufficient, safe and nutritious food.

Oat is one of the cereal crops in Ethiopia, which is less recognized in terms of its food value and productivity. It is grown and utilized as a staple food only in a specific part of the country. The objective of this study was to assess the food significance of oat and document associated traditional food knowledge of the crop in Gozamin district, Northwest part of Ethiopia. Data were collected using a semi-structured questionnaire, focus group discussion and key informant interviews. Secondary data collected from Gozamin agriculture development offices and research centers were used to support our results. A total of 388 households participated in this cross-sectional study. Data were edited, coded, entered and analyzed using SPSS for windows version 20.0. The results of this study affirmed that 97.2% of the producers cultivated oat every year and high rainfall is the suitable weather condition for its production. As per the results of this study, oat is tolerant to acidic and marginally fertile soils where other plants do not grow and yield well. As compared to other conventional cereal crops, 85% of the participants of the study reported that the cultivation of oat does not require extensive farming and can be produced with minimum inputs. The entire population of respondents (100%) reported that oat grain was used as food. Almost all the respondents (99.2%) utilized oat as their staple crop for their families. Oat ranked first in terms of consumption at household level as compared to other cereal crops (tef, maize, wheat, and barley). In the district, oat is processed into different food types and beverages including injera, kitta/anababiro, gruel, porridge, enket, and local alcoholic drinks, tella. Oat is rarely used to prepare porridge and local alcoholic beverages as compared to other cereal-based staple food types. Porridge and local alcoholic beverages are commonly prepared for special occasions and on holidays. Oat is a less known crop in specific locations but could contribute to enhancing food diversity options to improve food and nutrition security efforts in the country.

Protein-energy malnutrition is common among children of under five years of age in sub-Saharan Africa. This is mainly attributed to poor complementary foods and feeding practices, which are often cereal-based and characterized by low nutrient density. Soybean is commonly used to enrich complementary foods, nonetheless, its prospects for use as a rich source of protein and minerals is limited by its low protein digestibility and bioavailability of minerals, costly production and contribution towards environmental degradation. Crickets provide cheap and sustainable source of protein and other nutrients, and holds the potential for substituting soybean in complementary porridge formula. To evaluate acceptability of complementary porridge enriched with crickets, Famila complementary porridge flour, a composite of maize, wheat and defatted soybean was enriched with cricket flour by substituting soybean with cricket flour at 0%, 25%, 50% and 75%. Four porridges were prepared from the flours and coded as CP, CPB1, CPB2 and CPB3, respectively. A total of 40 semi-trained women evaluated the porridges on colour, taste, aroma, texture, mouth-feel and overall acceptability on a 9 -point hedonic scale. The overall acceptability of the porridges were as follows; CP (8.5±0.72), CPB1 (7.08±0.94), CPB2 (5.75±1.53) and CPB3 (3.60±1.95). Control porridge (CP) was highly rated in all sensory attributes while CPB3 was rated the lowest in all the attributes. Unlike CP, the overall acceptability of CP1, CPB2 and CPB 3 improved with experience in insect consumption, age and level of education. The ratings for colour, aroma and taste of cricket-based porridges were higher among women aged30 years and above, and those with post-primary education. The most accepted cricket-based porridges were CPB1 and CPB2. Enrichment of Famila complementary porridge with cricket flour affected its sensory attributes which were perceived differently by the women. This informs the need for both low and high substitution levels to cater for their diverse preferences.
Solar Panel Automatic Positioning and Maximum Light Flux Direction Tracking
Authors: Selivanov K.V.
Published: July 2021

The paper analyzes the state and possible ways of development of alternative energy, describes the prospects for the development of solar power plants, their classification and areas of application. Within the research, we revealed the problems that arise when installing and operating solar panels and identified the reasons that reduce their efficiency. Consequently, we analyzed the ways to increase the efficiency of power generation by solar panels and suggested solar panel automatic positioning and maximum light flux direction tracking as a possible solution to the problem. The study introduces a new device for positioning solar panels, which is distinguished by the automatic deployment and positioning of solar panels according to the actual direction of the maximum light flux. The device provides possible automation of the installation and greater efficiency of solar panels. The novelty of the device is protected by a utility model patent no. 180765 RF. To confirm the efficiency and to obtain a quantitative value of the increase in power generation by solar panels due to the use of the developed device, we present the comparison methodology and a description of the experiment. The schematic diagram and external view of the developed device are also shown. The experimental results are processed and shown in a graph. The possibility of increasing power generation by solar panels by tracking the maximum light flux and reorienting the solar panel towards it during the day has been confirmed, and a quantitative value of the increase in power generation has been obtained. Based on the positive results of the experiment, the possibility of using the developed device for automating the process of deploying solar panels in an autonomous way and excluding human participation in this process is described. The operation of the developed device on a moving vehicle and other methods of its application are considered. The results are summed up, conclusions are drawn and possible further directions for the development and use of the proposed method for increasing the efficiency of solar panels and the developed device for improving the performance of solar panels are identified
Symmetric Control Systems
Authors: Diveev A.I. , Sofronova E.A.
Published: July 2021

The paper focuses on the properties of symmetric control systems, whose distinctive feature is that the solution of the optimal control problem for an object, the mathematical model of which belongs to the class of symmetric control systems, leads to the solution of two problems. The first optimal control problem is the initial one; the result of its solution is a function that ensures the optimal movement of the object from the initial state to the terminal one. In the second problem, the terminal state is the initial state, and the initial state is the terminal state. The complexity of the problem being solved is due to the increase in dimension when the models of all objects of the group are included in the mathematical model of the object, as well as the emerging dynamic phase constraints. The presence of phase constraints in some cases leads to the target functional having several local extrema. A theorem is proved that under certain conditions the functional is not unimodal when controlling a group of objects belonging to the class of symmetric systems. A numerical example of solving the optimal control problem with phase constraints by the Adam gradient method and the evolutionary particle swarm method is given. In the example, a group of two symmetrical objects is used as a control object
New coronavirus infection in children in the Moscow region: clinical, epidemiological and treatment aspects

Published: July 2021

Aim: To assess clinical and epidemiological characteristics, as well as treatment results in COVID-19 pediatric patients hospitalized to the Department of infectious disease in the Moscow region. Materials and methods: We retrospectively analyzed medical records of 124 pediatric patients aged from 1 month to 17 years with confirmed (63.7%) and highly probable (proven epidemiological association with the infection source) COVID-19 infection. The children were hospitalized from March 25, 2020 to August 11, 2020. Among patients that were hospitalized during this time period, 43% had pneumonia and 30% had acute respiratory disorders. All cases of pneumonia were confirmed by computed tomography. The children were treated according to the standard Russian guidelines.

Results: The children had been infected with SARS-CoV-2 mostly from family members (75%; 95% confidence interval (CI) 66.4-82.3). In the families of the children with pneumonia, the number of pneumonia cases in their relatives was higher than in the families of the children with acute respiratory infections (1.7 ±1.0 vs. 1.1 ± 0.5 respectively; р < 0.001). The mean age of the hospitalized children was 8 years (7.4-9.6), with an even age distribution. The main COVID-19 signs and symptoms were as follows: fever (75.8%; 95% CI 67.3-83.0), cough (66.1%; 95% CI 57.1-74.4]), fatigues (38.7%; 95% CI 30.1-47.9), and hyposmia (33.9%; 95% CI 25.6-42.9). The severe disease course was rare (2.4%; 95% CI 0.5-6.9). The rates of positive reverse transcriptase polymerase chain reaction tests for SARS-CoV-2 were rapidly decreased at repeated tests: at day 3, 63.7% of the tests were positive, at day 7, 21.8% and at day 14, 5.6% (р < 0.001). The prevalence of pneumonia was 56.4% without any age differences, with mostly minimal areas of lung abnormalities (78.6%). The severity of pneumonia and duration of clinical manifestations in the patients treated with a III generation cephalosporin or its combination with a macrolide were similar. Cough duration in those, who were treated with ipratropium bromide / fenoterol inhalations including their combination with budesonide, was higher than in those who did not use inhalation treatment. Pyrexia of > 5 days duration can be a predictor of pneumonia in a pediatric patient with COVID-1 9 (odds ratio 4.55 (2.1-9.9), sensitivity 61.4%, specificity 74.1%).

Conclusion: The results obtained are important to develop further treatment strategies for children with COVID-1 9.

Bombax costatum est une espèce agroforestière menacée de disparition du fait des fortes pressions anthropiques qu’elle subit par le prélèvement de son calice. La présente étude a pour objectif d’évaluer l’influence des modes d’affectation des terres sur les caractéristiques dendrométriques, les types morphologiques et la phénologie de B. costatum dans la Réserve de biosphère de la Pendjari (RBP). Quatorze placeaux de 200 m × 200 m répartis dans quatre modes d’affectation des terres (zone d’occupation contrôlée, chaîne de l’Atacora, zone cynégétique de la Pendjari et Parc national de la Pendjari) de la RBP ont été inventoriés. Les données telles que le diamètre à hauteur de poitrine, la hauteur totale, le nombre d’individus, l’aspect de l’écorce et la couleur des fleurs ont été collectées. Les caractéristiques structurales de B. costatum ont été évaluées à trois niveaux : les paramètres dendrométriques dont la densité, le diamètre moyen, la surface terrière et la hauteur moyenne ; les structures en diamètre ; la distribution de fréquence des différents types morphologiques obtenus (aspect de l’écorce, couleur de la fleur). Pour tester les différences entre les modes d’affectation des terres, une ANOVA, une analyse log-linéaire et une analyse de covariance ont été effectuées respectivement sur les paramètres dendrométriques et les types morphologiques suivant les modes d’affectation des terres. Le mode d’affectation des terres a un effet significatif (P < 0,05) sur la densité des individus adultes, le diamètre moyen, la hauteur moyenne, les types morphologiques et la phénologie de B. costatum. La densité des individus adultes est plus élevée dans les zones d’occupation contrôlée et la chaîne de l’Atacora. Il ressort des résultats que l’espèce a encore un potentiel semencier qui assure sa pérennisation mais qu’une utilisation contrôlée est nécessaire pour sa conservation durable.

Published: July 2021

Au Bénin, les déchets issus de la transformation du bois sont très insuffisamment valorisés dans une perspective de réutilisation par l’industrie du bois. Les technologies de transformation de ces produits connexes, économiquement accessibles aux populations des pays en développement, constituent un domaine très peu abordé dans la littérature internationale. Dans le présent travail, un matériau constitué d’un mélange de sciure de bois de teck et de pâte de polystyrène recyclés, suivant une technologie simple à mettre en œuvre et de type low-tech, a été caractérisé. Les résultats obtenus ont montré que les propriétés du composite varient significativement avec la granulométrie de la sciure utilisée. La masse volumique apparente du matériau est comprise entre 686 à 826 kg/m3, son taux d’absorption d’eau est inférieur à 15 % et son taux de gonflement en épaisseur est inférieur à 5 % après 24 heures d’immersion. Une corrélation élevée a été observée entre ses propriétés physiques et sa porosité qui varie de 34 et 43 % suivant la granulométrie des sciures de bois utilisées. Le composite présente un module d’élasticité en traction compris entre 582 à 1 057 MPa, une résistance en traction comprise entre 2 et 3 MPa et un coefficient de Poisson variant de 0,14 à 0,24. En compression, son module d’élasticité varie entre 270 à 470 MPa et sa résistance entre 6 à 9 MPa. Une mise en œuvre du composite ainsi élaboré peut être envisagée en substitution du bois pour des éléments faiblement chargés comme des pièces de coffrage de construction légère.

Authors: Shafira Konita , Bakar Abu , Wahyuni Erna Dwi
Published: July 2021

Introduction : Diabetes Mellitus (DM) is a group of metabolic diseases characterized by hyperglycemia caused by abnormalities in insulin secretion, thus impacting on blood glucose levels. Calabura muntingia leaves are traditionally used as an alternative medicine because they contain flavonoid compounds which have anti-diabetic properties. In general, it is known that how to make traditional medicine is by boiling it, where the solvent only uses water so that the polar compounds will be attracted. The purpose of this study is to explain effectiveness the effect of administration between calabura muntingia leaves and calabura muntingia fruit through a review of studies related to blood sugar levelsin the last ten years.Method : Search for journals or articles using Scopus, Proquest, and Scholar indexed databases using appropriate keywords. The Center for Review and Dissemination and The Joanna Briggs Institute was used to assess the quality of the study. The framework used for the review is PICOS and the inclusion criteria used are English and Indonesian journals published in 2010 to 2020. Data analysis and tabulation are carried out in articles or journals. Title, abstract, full text and methodology are assessed to determine the eligibility of the article or journal.Results : Six hundred and forty-one articles were identified, there were eleven articles that fit the research criteria. The leaves of muntingia calabura and fruit of muntingia calabura contain flavonoids and saponins which can reduce blood sugar levels. A flavonoid compound that is thought to have activity in reducing blood glucose levels is quercetin.Conclusion : The form of extract, infusion, juice and stew did not change the content of the calabura muntingia plant.

Published: July 2021

In this study, the components of a particular heavy commercial truck that affect the steering wheel vibration are identified and the most common sources of this vibration are examined. Then, modal analyses and impact hammer tests are implemented to determine the root causes of the vibration. Finally, finite element modeling is applied, and all the results of the analyses are compared to present design improvement recommendations for the reduction in steering wheel vibration, which can be applicable in new projects.

Published: July 2021

Analytical mathematical models and solutions for spatial localization of acoustic waves through an impedance discontinuity produced by an intermediate damped side branch are studied in stationary media in ducts with varying cross sections. Three specific geometries, namely, with polynomial, sinusoidal, and exponential longitudinal variations, are investigated. The sound fields inside the ducts are modeled by Webster's horn equation. Traveling-wave solutions are obtained by appropriate transformations. The side-branch impedances required for spatial localization (confinement) of traveling and standing waves are found analytically and verified numerically using three-dimensional finite element analysis. The impact of the longitudinal variation of the duct's cross-sectional area (CSA) on the side-branch impedance is examined. It was found that the required side-branch resistance changes more than the reactance with the variation of the duct CSA. A measure of a traveling wave is defined to quantitatively examine the spatial localization of acoustic waves. It was found that the CSA corrections on the side-branch impedances are important. The results of this study reveal the quantitative relationships between the side-branch impedance and the CSA variations for zero reflection from the impedance discontinuity. The mathematical approach presented is potentially helpful for a design of a full anechoic termination and energy localization in duct systems.

Authors: López-Guzmán Tomás , Borges Osvaldo , Castillo-Canalejo Ana María
Published: July 2021

Community-based tourism is taking its place in the world as an alternative to traditional tourist destinations, especially in developing countries. This form of tourism allows for greater contact with the local community and for the tourist to experience new sensations while enabling the economic and social development of the geographic area. In this paper, the results of fieldwork carried out in the island of Fogo (Cape Verde) are presented, assessing the opinion and perception tourists visiting this island have of both the quality of the services offered by community-based tourism enterprises, as well as the potential of the tourism resources in the area. The main results of the investigation endorse the quality of services offered to tourists by local businesses and highlight the hospitality of the local community, a key element for the development of this kind of tourism, particularly in different african countries. Similarly, it highlights the passenger satisfaction with services received and the need to strengthen the training to tourism staff through aid, for example, international cooperation, NGOs and universities. The originality of this research comes from analysis of the demand made on a concrete island of Cape Verde, a country which is producing a huge economic development through the tourism sector.
Coping with climate change in the tourism industry: a review and agenda for future research
Authors: Hernandez Ana Beatriz , Ryan Gerard
Published: July 2021

The two-way relationship between tourism and Climate Change has important economic and developmental implications for numerous regions worldwide. Purpose: The purpose of this paper is to present an overview of the existing literature on the relationship between tourism and climate change in order to establish the current state of corporate and institutional responses in the tourism industry and to set out an agenda for research. Methodology: As this is a literature review paper, a comprehensive review was undertaken of the management journals and related topics. Findings: The global or overall impact of tourism on climate has received little attention by researchers. In general, the majority of companies are still in a preliminary phase in terms of implementing adaptation and mitigation measures. There is a requirement to examine the determinants of these strategies in organisations, as well as their associated outcomes. There is a need to examine tourist preferences in terms of activities and destinations, the impacts of climate change, and whether and how this affects tourist-consumer decision making. Academic research has focused mostly on specific and individual solutions to address the impact of climate change on tourism. The analysis of the interplay of these measures and their possible synergies constitute an important topic for future research. Originality: The timeliness of the review is evident given the recent surge in popular debate on climate change, its effects on tourism and the appearance of a broad and disparate array of studies on this topic.

Legacy IPv4 networks are strenuous to manage and operate. Network operators are in need to minimize the capital and operational expenditure of running network infrastructure. The implementation of Software-defined networking (SDN) addresses those issues by minimizing the expenditures in the long run. Legacy networks need to integrate with the SDN networks for the smooth migration towards the fully functional SDN environment. In this paper, we compare the network performance of the legacy network with the SDN network for IP routing in order to determine the feasibility of the SDN deployment in the Internet Service provider (ISP) network. The simulation of the network is performed in the Mininet test-bed and the network traffic is generated using distributed Internet traffic generator. Open network operating system is used as a controller for the SDN network in which SDN-IP application is used for IP routing. Round trip time, bandwidth, and packet transmission rate from both SDN and legacy networks are first collected and then the comparison is done. We found that SDN-IP performs better in terms of bandwidth and latency as compared to legacy routing. The experimental analysis of interoperability between SDN and legacy networks shows that SDN implementation in production level carrier-grade ISP network is viable and progressive.
On the Use of Entropy as a Measure of Dependence of Two Events
Authors: Iliev Valentin
Published: July 2021

We define degree of dependence of two events A and B in a probability space by using Boltzmann-Shannon entropy function of an appropriate probability distribution produced by these events and depending on one parameter (the probability of intersection of A and B) varying within a closed interval I. The entropy function attains its global maximum when the events A and B are independent. The important particular case of discrete uniform probability space motivates this definition in the following way. The entropy function has a minimum at the left endpoint of I exactly when one of the events and the complement of the other are connected with the relation of inclusion (maximal negative dependence). It has a minimum at the right endpoint of I exactly when one of these events is included in the other (maximal positive dependence). Moreover, the deviation of the entropy from its maximum is equal to average information that carries one of the binary trials defined by A and B with respect to the other. As a consequence, the degree of dependence of A and B can be expressed in terms of information theory and is invariant with respect to the choice of unit of information. Using this formalism, we describe completely the screening tests and their reliability, measure efficacy of a vaccination, the impact of some events from the financial markets to other events, etc. A link is available for downloading an Excel program which calculates the degree of dependence of two events in a sample space with equally likely outcomes.
The Optimal Harvest Decisions for Natural and Artificial Maturation Mangoes Under Uncertain Demand, Yields, and Prices
Authors: Chen Sheng-I , Chen Wei-Fu
Published: July 2021

This study focuses on the decisions of picking, inventory, ripening, delivering, and selling mangoes in a harvesting season. Demand, supply, and prices are uncertain, and their probability density functions are fitted based on actual trading data collected from the largest spot market in Taiwan. A stochastic programming model is formulated to minimize the expected cost under the considerations of labor, storage space, shelf life, and transportation restrictions. We implement the sample-average approximation to obtain a high-quality solution of the stochastic program. The analysis compares deterministic and stochastic solutions to assess the uncertain effect on the harvest decisions. Finally, the optimal harvest schedule of each mango type is suggested based on the stochastic program solution.

The SARS coronavirus 2 pandemic affected many areas of public life and industry. This also applies to research particularly that which relies on user test studies. In order to minimize the risk of infection, several aspects of experiment design including the setting might require alteration. In order to develop a step-by-step approach to plan a study with regard to infection protection, an extensive review of the latest research involving the SARS coronavirus 2 pandemic as a blueprint for dealing with other health situations. As a result, a six-step concept was developed that is applicable for user test studies in both stationary rooms and vehicles which can be adapted to the respective circumstances. The infection protection measures determined through research were implemented in the individual sub-steps from study planning to execution. They allow a step-by-step approach to prevent infections in user test studies during a pandemic and in situations where increased hygiene measures are required, in order to continue to carry out user test studies.
