Las artes pueden generar transformaciones que contribuyen a mejorar la vida de las personas. Abordar fenómenos culturales del ámbito de la lengua y la literatura desde esta perspectiva puede favorecer las relaciones humanas de calidad, lo cual influye notablemente en el desarrollo de trayectorias de vida longevas, felices y saludables. Este artículo analiza cómo el fenómeno del versolarismo improvisado en euskera (bertsolaritza) se ha convertido en un movimiento social que trabaja para crear espacios de socialización en los que se tejen redes de amistad entre las personas participantes. Desde una metodología de investigación que posibilita la co-creación igualitaria de conocimiento, 32 personas del ámbito del versolarismo fueron entrevistadas. Los resultados del estudio coinciden con las investigaciones publicadas anteriormente, ya que sugieren que el espacio de la cultura puede promover la construcción de relaciones igualitarias y que ello posibilita transformaciones profundas que mejoran la vida de las personas.
Implementation of the CEFR in the rubrics of two main English Certificates: Cambridge FCE and Trinity ISE-II.
Authors: Fraga Viñas Lucía
Published: July 2021

The Common European Framework of Reference (CEFR) was developed by the European Council with the intention of providing a comprehensive basis for the creation language syllabi and curriculum guidelines, together with the design of teaching materials, language certificates and instruments of assessment. The CEFR has been implemented in Spain through different education laws and has prompted the introduction of the communicative approach and the use of new instruments of assessment such as rubrics. Nonetheless, almost twenty years after the CEFR was passed, not many researches have been conducted on how the Framework has been implemented. It is from this line where the current research stems as it intends to check how the CEFR has been adapted in the rubrics used for the assessment of the writing skill in two main English Certificates: the Cambridge Assessment English FCE and the Trinity College ISE-II.

El Marco Común Europeo de Referencia (MCER) se desarrolló con el objetivo de promover una base común para la creación de currículos educativos y servir como guía en la elaboración de materiales didácticos, exámenes de certificación e instrumentos de evaluación. El MCER se ha implantado en España a través de diferentes leyes educativas y ha propiciado la introducción del enfoque comunicativo o nuevos instrumentos de evaluación como rúbricas. Sin embargo, casi veinte años después de la aprobación del marco, pocos son los estudios que han revisado de qué manera se ha adaptado el marco. Es aquí donde la presente investigación se sitúa, con el objetivo de comprobar cómo se ha implementado el MCER en las rúbricas para examinar la destreza escrita de dos de los principales certificados de inglés: el Cambridge Assessment English FCE y el Trinity College ISE-II.

Authors: Susanti Hilda
Published: July 2021

The community service activity entitled the application of jasmine cultivation based on the gap in the Jingah Habang ilir floriculture area of Banjar district was carried out on September 12, 2019. This activity was carried out in the form of training with lecture methods, discussions/questions and answers, and quizzes. This activity aims to (1) provide knowledge and guidance to farmers regarding jasmine cultivation based on GAP, (2) assist local governments in developing floriculture areas in Banjar Regency. The target audience of this community service activity are jasmine producing farmers in the floriculture area of Jingah Habang Ilir village, Karang Intan district, Banjar district, South Kalimantan. The results of community service were measured descriptively from the responses given during the training activities, as well as from the follow-up carried out by producer farmers after the training. Follow-up by producer farmers is seen from filling out questionnaires carried out by 10 producer farmers in 2021. The level of achievement can be achieved through changes in thinking and attitudes in carrying out jasmine cultivation based on GAP. Based on the findings in this community service activity, it can be seen that the jasmine cultivation that has been carried out by producer farmers only uses empirical science, namely science based on the experience of ancestors, as well as "trial and error" that occurs in the field. The evaluation carried out after 1.5 years of training in 2021 showed that the implementation of the GAP for jasmine cultivation that had been carried out by farmers was 100% having carried out land management both using machines and human power. Farmers have prepared the seeds according to the recommendation, namely 90% have used stem cuttings with a brownish green color. Farmers have provided complete fertilizer containing N, P, and K, of which 40% have fertilized 3 times a year.  Farmers still need assistance to apply GAP to other components of cultivation practices to make the floriculture area in Banjar district sustainable.

The phenomenon of the Kosach-Dragomanov family is considered in this article as a national archetype of the Ukrainian mentality, the influence of this family on the formation of such an aristocratic personality as Lesіa Ukrainka during difficult times of socio-political life. Special attention has been paid to the creative and human relationships between Lesia and her uncle Mykhailo Drahomanov whose influence on her was undeniable and extremely beneficial. Her pedigree in particular has been traced. Heredity of generations, the appearance of ingenious personalities is always the subject of special attention. The decisive moment in defining these processes is the appearance of new people, more precisely people of new formation, people of progressive thinking, who are the driving force and foundation of historical change. New generations should not be indifferent to their great predecessors. Lesіa Ukrainka as a creative nature could not be indifferent to the talents and skills of talented people, the circle of her friends, acquaintances and supporters was extremely wide as well as the measurement of her interests. The subject of this article is to highlight the important role of the family and the environment in general in forming a young person as a personality. The challenges of the modern times, in particular, in the field of humanistic educational tendencies, require an appeal to moral authorities in the history of the development of the Ukrainian nation.

Evaluation of red sludge use efficiency for water purification from sulphates
Authors: Gomelya Mykola , Kryzhanovska Yana , Shabliy Tetiana
Published: July 2021

In this work the reagent purification of aqueous solutions from sulfates with the use of red sludge of the Nikolaev alumina plant processes were investigated. This sludge, according to chemical analysis, contains a sufficiently large amount of alumina (up to 18 %) and calcium oxide (up to 10 %) and along with calcium silicate and iron oxides contains sodium and calcium aluminates. The ability of sodium aluminate to be deposited from a solution of sulfates in the form of calcium sulfoaluminates was used in the work to purify water from sulfate anions. The process takes place when treating the solution with sludge and lime suspension. It is shown that when red sludge is applied in the amount of 1–50 g/dm3 during magnesium sulfate solutions liming, water is purified from sulfate anions. The degree of water purification reaches 50–70 %. It was found that the efficiency of sulfate extraction is significantly dependent on the consumption of lime and increases slightly with increasing sludge consumption over 1 g/dm3. The dependence of the efficiency of sulfate extraction from water on their initial concentration is determined. It was found that at the initial concentration of sulfates up to 1000 mg/dm3 at the expense of lime 3–12 mg-eq/dm3 the residual concentration of sulfates decreases to 236–460 mg/dm3, and at the concentration of sulfate anions about 2000 mg/dm3 their concentration decreases to 550–830 mg/dm3 at a lime consumption of 30 mg-eq/dm3 regardless of the sludge consumption. The degree of extraction of sulfates from solutions reaches 40–73 %.
Features of isothermal crystallization of ammonium sulphate

Published: July 2021

Soil fertility is rapidly decreasing due to irrational land use, erosion and soil pollution and adverse weather conditions. The use of composite granular organic-mineral fertilizers that contain mineral and organic components allows the soil fertility to be increased in the most effective and safe manner for the environment. In the production of granular composite fertilizers in a fluidized bed granulator, the process of isothermal mass crystallization is the main parameter that affects the quality.

The effect of impurities on the morphological structure of ammonium sulfate microcrystals during mass crystallization on the surface was investigated by means of microscopic analysis. The influence of temperature and pH of the solution on the structure and shape of the microcrystal layer was studied.

The process of mass crystallization depends on the presence of impurities, pH and temperature. Given the fact that there is no analytical or theoretical dependence describing the influence of impurities on the morphological structure, the influence is determined experimentally. The presence of even a small content of surfactants and other impurities in the ammonium sulfate solution has a significant effect on the morphological structure of ammonium sulfate microcrystals, which is revealed as reduction in the concentration of impurities in ammonium sulfate obtained by coke-chemical method. The pH level of the medium affects the structure and shape of microcrystals: smaller crystals with a layered structure are formed in the case of weakly alkaline medium with pH = 8 and smaller microcrystals with a granular structure are formed in the case of pH = 4. Therefore, it is important to maintain the required pH level of the medium during the mass crystallization of ammonium sulfate.

In isothermal mass crystallization of saturated aqueous solutions of ammonium sulfate with humic compounds and bone meal proceeding on a surface with temperature 90 °C, small elongated crystals with microcrystal sizes from 10 to 100 μm are formed. Impurities of bone meal and humic compounds in the form of inclusions are placed between the crystals of ammonium sulfate: namely, the endosegregation of impurities in the microcrystalline framework is observed. As the concentration of organic matter in the solution increases, which crystallizes as droplets on the surface, rubble and dendrites are formed outside the initial droplet placement. This phenomenon is explained by the increase of diffusion resistance at the center of the drop; as a result, ammonium sulfate crystallizes in the zone with lower resistance.

The process of isothermal mass crystallization of saturated aqueous solutions of ammonium sulfate with admixtures of humic compounds, bone meal and other target components in the specified ratios will create new highly effective fertilizers. The obtained results allow formulating theoretical bases for the formation of solid structures based on ammonium sulfate with admixtures of organic and mineral components.
Reduction of water chromaticity by materials with capillary properties
Authors: Radovenchyk Yaroslav , Krysenko Tamara , Poberezhnyi Maksym , Radovenchyk Vіacheslav
Published: July 2021

The presence of a significant amount of plant and animal organic residues in the environment leads to intensive pollution of natural waters and significant deterioration of water chromaticity. Ukrainian regulatory documents on the quality of drinking water establish a level of 20 degrees for water chromaticity. Hence, in most cases, natural water must be additionally treated before consumption. The coagulation, flocculation, filtration and flotation are today the most widespread methods for normalizing the water chromaticity level. All these processes are quite complex and expensive, require the use  of additional reagents and lead to secondary water pollution. The use of materials with capillary properties is a promising method since it simultaneously ensures the liquid phase transport without excess pressure and water cleaning from various pollutants. This method, used to reduce water chromaticity, found that sufficient efficiency could be provided only for the initial water chromaticity level within 20 - 80° CCS and at pH level within 2.0 - 4.0. Under other conditions, all studied tissue samples as a material for capillary filter, such as cotton, linen, polyester and gabardine, did not provide the value of water chromaticity required for drinking water. Even worse results were obtained for water with initial chromaticity more than 80 degrees. Considering that the described method can provide the maximum efficiency only in a highly acidic medium, it is assumed that the surface charge of the capillary filter fibers and humic acid particles could be the critical factor in the reduction of water chromaticity. In a wide pH range, the surface of the humic particles is charged mainly negatively. The surface of cellulose fibers is also negatively charged in the pH range of 2.0 - 11.0. Therefore, the results of experiments can be explained from this point of view. There are no research data in these fields at all. One of the possible ways to improve the efficiency of water chromaticity reduction by the proposed method is to select fabrics with appropriate physicochemical surface properties. Also, capillary filtration process can be treated with special reagents for giving the fiber surface the required charge. Water treatment by series of several connected capillary filters can be a promising way. In general, given the simplicity of the filter design, low total cost of the water treatment process, and zero energy losses, the studied method is quite promising for industrial implementation and needs more detailed research.

Published: July 2021

This paper presents the results of numerical investigation, calculation analysis and experimental study of heat exchange in a system of plane-parallel channels formed by rectangular fins, which are applied in a heat removal device using heat tubes for power semiconductor energy converters. Passive cooling (heat removal by radiation and natural convection) and active cooling (heat removal by radiation and forced convection) are investigated for various velocities of air cooling of fins by spherical vortex generators applied to its surface. A comparative analysis of the results is carried out for the average effective heat removal resistance and for the average temperature at the ends of the fins. The application of numerical modeling to solve such problems confirms the effectiveness of computational technologies. The difference between the results of the study ranges from 10 to 16% depending on the airflow rate.

Published: July 2021

A system belonging to the class of dynamical systems such as Buslaev contour networks is investigated. On each of the two closed contours of the system there is a segment, called a cluster, which moves with constant velocity if there are no delays. The contours have two common points called nodes. Delays in the motion of the clusters are due to the fact that two clusters cannot pass through a node simultaneously. The main characteristic we focus on is the average velocity of the clusters with delays taken into account. The contours have the same length, taken to be unity. The nodes divide each contour into parts one of which has length d, and the other, length 1-d. Previously, this system was investigated under the assumption that the clusters have the same length. It turned out that the behavior of the system depends qualitatively on how the directions of motion of the clusters correlate with each other. In this paper we explore the behavior of the system in the case where the clusters differ in length.

Background. January 2021 marked one year since the start of COVID-19 pandemic: it is the time of intermediate conclusions. Objective. To evaluate CFR and IFR due to COVID-19 in various countries and territories, and to study if parameters of a population age affect CFR and IFR. Material and Methods. The databases of 219 countries were collected on the Worldometers, Index Mundi, Country Meters and World Bank websites. The processing of data was divided into two parts: the first part dealt with the calculation and analysis of CFR while the second, the calculation and analysis of IFR. Results. The calculations revealed that in 74 out of 219 countries, CFR was less than 1.00 %, in 69 countries it varied between 1.00 % and 2.00 %, and in 76 countries it was more than 2.00 %. The calculation of IFR revealed that in 183 countries, IFR was less than 1.00 %, in 22 countries IFR was between 1.00 % and 2.00 %, and only in 14 out of 219 countries IFR was more than 2.00 %. A correlation between IFR and parameters of a population age was found: the less median age and the percentage of 'aged' people – the less value of IFR, although, there was no correlation between parameters of a population age and CFR. Conclusion. The global health care system has gone through a year of serious trial caused by COVID-19 and appeared to have emerged victorious. In the majority of countries analyzed, the parameters of mortality due to COVID-19 were at a low level. So, there seems to be an objective basis for optimism and hope for an early end to the pandemic.
ADVANCED TYPES OF CHECKERWORK OF REGENERATIVE HEAT EXCHANGERS FOR GLASS FURNACES
Authors: Koshelnik O. , Hoisan S.
Published: July 2021

One of the ways to increase glass furnaces energy efficiency is to apply heat exchangers for flue gases thermal potential utilization.

Flue gases losses is up to 25-40 % of the total amount of heat supplied in the furnace. These losses are influences by such factors as fuel type, furnace and burners design and manufactured product type.

Regenerative heat exchangers with various types of heat storage packing is more efficient for high-power furnaces.

Such types of regenerator checkerwork as Cowper checkerwork, two types of Siemens checkerwork, Lichte checkerwork and combined checkerwork have already been sufficiently researched, successfully applied and widely used for glass furnaces of various designs. All of its are made of standard refractory bricks. Basket checkerwork and cruciform checkerwork that are made of fused-cast molded refractory materials have been widely used recently as well.

Further improvement of regenerative heat exchangers thermal efficiency only by replacing the checkerwork does not seem possible unless their size being increased. But this enlarging is not always realizable during the modernization of existing furnaces.

From this point of view heat storage elements with a phase transition, where metal salts and their mixtures are used as a fusible agent look promising for glass furnaces.

These elements can accumulate additional amount of heat due to phase transition, which allows to increase significantly heat exchanger thermal rating without its size and operating conditions changing.

However, it is necessary to carry out additional studies of this type of checkerwork dealing with analysis of complex unsteady heat exchange processes in regenerators and selection of appropriate materials that satisfy the operating conditions of regenerative heat exchangers so that the checkerwork can be widely used for glass furnaces.
RESEARCH OF EXTERNAL MASS TRANSFER PROCESSES FOR ADSORPTION FROM SOLUTIONS IN A APPARATUS WITH STIRRING
Authors: Solovej V. , Gorbunov K. , Vereshchak V. , Gorbunova O.
Published: July 2021

A study has been mode of transport-controlled mass transfer-controlled to particles suspended in a stirred vessel. The motion of particle in a fluid was examined and a method of predicting relative velocities in terms of Kolmogoroff’s theory of local isotropic turbulence for mass transfer was outlined.

To provide a more concrete visualization of complex wave form of turbulence, the concepts of eddies, of eddy velocity, scale (or wave number) and energy spectrum, have proved convenient.

Large scale motions of scale contain almost all of the energy and they are directly responsible for energy diffusion throughout the stirring vessel by kinetic and pressure energies. However, almost no energy is dissipated by the large-scale energy-containing eddies. A scale of motion less than is responsible for convective energy transfer to even smaller eddy sires. At still smaller eddy scales, close to a characteristic microscale, both viscous energy dissipation and convection are the rule. The last range of eddies has been termed the universal equilibrium range. It has been further divided into a low eddy size region, the viscous dissipation subrange, and a larger eddy size region, the inertial convection subrange.

Measurements of energy spectrum in mixing vessel are shown that there is a range, where the so called -(5/3) power law is effective. Accordingly, the theory of local isotropy of Kolmogoroff can be applied because existence of the internal subrange. As the integrated value of local energy dissipation rate agrees with the power per unit mass of liquid from the impeller, almost all energy from the impeller is viscous dissipated in eddies of microscale.

The correlation for mass transfer to particles suspended in a stirred vessel is recommended. The results of experimental study are approximately 12 % above the predicted values.

The urgency of the work is due to the large use of modern industry centrifugal pumps for pumping viscous liquids. In the energy sector, this is the use of fuel oil and thermal power plants, mineral oils and oil and gas-based lubricants as reserve fuel, and so on.The use of the characteristics of centrifugal pumps for viscous substances requires their recalculation. These data show the relevance of the problem of recalculating the characteristics of centrifugal pumps for viscous substances.In the oil industry, thousands of centrifugal pumps operate at oil pumping stations and in oil refining processes.The conducted researches and the analysis of their results give the chance to control giving of the centrifugal pump in technological process of cracking of oil products on an example of application of ACS.Analytical researches of a technique of recalculations are given.The characteristic of centrifugal pumps by calculations of approximation coefficients by the method of least squares is given.The performed studies confirmed the theoretical data on the influence of liquid viscosity on the appearance of the characteristics of centrifugal pumps.Studies also show that a sufficiently high accuracy of calculations of characteristics from water to liquid is provided for high-speed pumps which are in the range n = 50–130, that is for low-speed and normal wheels of centrifugal pumps.With the improvement of fluid quality, the rotation of the wheel shaft deteriorates. Therefore, there is a need to have the characteristics of such pumps at different speeds. The construction of such characteristics is based on the theory of similarity of centrifugal pumps, from which the so-called proportionality formulas are obtained, which allow to list (Q–H) the characteristics of the pump when the speed changes.Bringing characteristics to the analytical form allows you to use the Ace feed control. The means of regulation by changing the speed provides a significant reduction in electricity consumption.These data show the relevance of the problem of recalculating the characteristics of centrifugal pumps for viscous substances.

Beijing opera enjoys a slightly higher frequency than Peking opera in total, and several Asian and African countries even have no relevant data concerning this art. Besides, we explore some potential reasons for interpreting these phenomena.

Authors: Sims Michael , Foropoulos Lauren , Bettin Clayton
Published: July 2021

Case:

Two type-2 diabetic patients presented with bilateral Charcot arthropathy with midfoot collapse and presence of foot ulcerations on one side. The ulcerated extremity in each patient was treated surgically with fusion bolt, beam, and plate constructs in the setting of open ulceration. Bilateral extremities were treated surgically and went on to bony union and wound healing.

Conclusion:

Charcot arthropathy with open ulcers can be managed acutely with debridement, resection of bone, and arthrodesis. Waiting for ulcers to heal before internal fixation is performed may not be necessary in all situations.

The main constraints to increase mungbean production in Indonesia are pests and diseases. The application of integrated biological agents can improve the efficacy of controlling the mungbean pests and diseases. The study aimed to determine the efficacy of integrated biological agents to suppress mungbean pests and diseases. This field research was conducted from May to July 2018 using a randomized block design with seven treatments and four replicates. The treatments were: T1 = Trichol + NSP, T2 = Trichol + SlNPV, T3 = Trichol + NSP + SlNPV, T4 = Trichol + NSP + SlNPV + BeBas, T5 = Trichol + NSP + SlNPV + BeBas + GE, T6 = chemical pesticides, and T7 = control. The results showed that the highest efficacy occurred in T4 and T5 treatments which saved the yield loss from major pests and diseases attack, and did not differ significantly with chemical pesticides (T6). Treatments T4 was able to reduce the development of soil borne diseases by 3% and suppress Spodoptera litura attack by 9.8% as compared to chemical treatment. T4 was also more efficient than T5 because it uses less biological agents. The advantage of biological agents is compatible if they were used together with predators such as Oxyopes sp., Paederus sp. and Coccinella sp; and also Telenomus sp. and Trichogramma sp. parasitoids. On the other hand, the chemical pesticides (T6) killed all existing natural enemies. Therefore, T4 could be recommended for controlling mungbean pests and diseases.

Published: July 2021

This study determines effects of raw material feed (derived from corn, bran, soybean pods, concentrates and Indigofera zollingeriana local to Magelang) on the performance of native chicks. Performance was measured by feed consumption, body weight gain, Feed Conversion Ratio (FCR), mortality, and morbidity. This experiment used Completely Randomized Design (CRD) with three different feed treatments, and each treatment consisted of 30 free-range female chicks as replicants, from 0-4 weeks old. Super native chick feed was formulated by trial and error by mixing all ingredients: corn, bran, soybean pods, Indigofera zollingeriana, and premix. After mixing, a proximate test determined the nutritional content of the feed. Feed was then administered to chicks. Quantity of feed was administered according to age. The results obtained in the study were analyzed descriptively and statistically using the Variance Test (ANOVA) for the variables of body weight gain, feed consumption, and FCR. The Kruskal Wallis test was used via SPSS 26 program for mortality and morbidity variables with three treatments (T1, T2, and T3) and three replications. Each treatment consisted of 30 research individuals. Results showed that the super native chicks on varied protein diets had a significant difference in performance (P0.05), with feed 3 performing the best feed 3 produced a feed consumption of 430.20 g/chick and body weight gain of 174.67 g/chick, along with 2.46 FCR, 0% mortality, and 3.33% morbidity. The conclusion this study is holistic feed made from local ingredients with the addition of Indigofera zolliengeriana had a significant effect on increasing average daily gain, increasing feed consumption, and reducing feed conversion ratio (FCR)  in native super chick.

This research aims to evaluate the protective potency of freeze-dried egg yolk powder on Garut ram sperm during the liquid semen preservation process. Semen with good sperm quality was divided into three groups and diluted using the following Tris diluents: fresh egg yolk-Tris (FEY-Tris), commercial egg yolk powder-Tris (CEY-Tris), and freeze-dried egg yolk powder-Tris (DEY-Tris). Semen that had been diluted was observed every 12 hours until sperm progressive motility was 50%. Sperm quality was tested for progressive motility percentages, viability, intact plasma membrane (IPM), and intact acrosome (IA). Fresh egg yolk had a particle size of 14460.00±330.76 nm, with polydispersity index value (PI) and zeta potential (ZP) being 1.00±0.11 and -9.22±0.30 mV, respectively. The particle size of commercial egg yolk powder was 877.90±168.86 nm with PI value 0.34±0.04 and ZP-28.7±1.24 mV. The particle size of freeze-dried egg yolk powder was 1296.00±86.73 nm, with PI value 0.70±0.04 and ZP -34.5±0.64 mV. Progressive motility percentage showed that DEY-Tris diluent managed to survive to 51.11±6.06% for 168 hours, compared to FEY-Tris (51.25±6.74%) which survived for 156 hours, although no longer than CEY-Tris diluent (53.47±6.33%) which survive for 180 hours (P0.05). Higher sperm motility was also supported by viability percentage, IPM, and IA, which were all higher (P0.05). In conclusion, freeze dried egg yolk powder mixed with Tris buffer was able to maintain sperm quality during the liquid semen preservation process.

Published: July 2021

O objetivo do estudo foi verificar a influência da subvenção e assistência governamental no desempenho das empresas listadas na B3. Para tal, realizou-se pesquisa descritiva, documental e quantitativa em companhias abertas que possuíam dados disponíveis para o período de 2011 a 2018, sendo que a amostra do estudo foi composta de 272 empresas. Os dados foram coletados no banco de dados Economática®. Posteriormente, foi realizada estatística descritiva e análise de regressão linear, no software estatístico STATA. Os resultados encontrados comprovam que as empresas que possuem subvenção e assistência governamental apresentam melhores indicadores de desempenho. O estudo contribui no sentido de entender que as empresas que recebem subvenção e assistência governamental se comprometem com o governo e a sociedade em fomentar o desempenho econômico e financeiro. Do contrário, empresas que estão propensas a não obter subvenção e assistência governamental apresentam desempenhos inferiores. Ademais, estas enfrentam uma concorrência desleal frente aos investimentos.

Published: July 2021

A dinâmica das decisões organizacionais perpassa desafios cuja complexidade, na maioria das vezes, está associada aos efeitos de seus desdobramentos. Além de fatores internos, o processo decisório é influenciado por condições políticas, econômicas e sociais. Nas Instituições de Ensino Superior (IES) da rede pública federal isso é ampliado por legislações específicas que estabelecem diretrizes para equacionar os recursos. Destarte, este trabalho utilizou o método Analytic Hierarchy Process (AHP) no auxílio à tomada de decisão sobre a seleção de um sistema de impressão em uma IES federal. Os resultados baseados na análise híbrida (qualitativa-quantitativa) do AHP ajudariam em termos de gestão, no desenvolvimento de competências e ativos-chave, na terceirização de ativos e, na definição de competências não essenciais. O caso apresentado neste trabalho demonstra como o AHP pode ser usado para auxiliar tomadas de decisão no setor público. Desta forma, pesquisadores, profissionais e gestores têm no framework metodológico apresentado um apoio.
