Published: February 2022

Biomass is a highly versatile renewable energy source used on a global scale. The paper discusses the current state of biomass energy use in the EU and Slovakia. Residual biomass was found as a key feedstock for the European bioeconomy. Slovakia is one of the most forested and rural countries in the EU. Therefore, biomass energy has the highest technical potential from all renewables in Slovakia. The main objective of the paper was to evaluate the phytomass production of the selected crops and their energy potential in individual self-governing regions of Slovakia. It is focused on the production of usable post-harvest residues theoretically used for energy purposes from the following studied main crops: wheat, rye, oats, barley, maize, potatoes, oilseed rape and sugar beet. The results show the estimated production of usable post-harvest residues of the selected crops and their energy potential in individual self-governing regions in Slovakia in 2019. The total production of usable post-harvest residues from the studied crops was 4,854,017 t and their estimated energy potential was 68 PJ. This amount of energy would cover 10% of the total energy consumption in Slovakia. The top three productive crops were maize, wheat, and sugar beet. Maize had the highest energy potential of 28.1 PJ, followed by wheat at 19 PJ and sugar beet at 14.2 PJ. The highest yields of post-harvest residues, as well as energy potential, were found in the Nitra region.

Probiotics in the gut-skin axis – the case of kefir
Authors: Alves Emilia , Rijo Patricia , Monteiro Rodrigues Luís , Rosado Catarina
Published: February 2022

The intestinal microbiota is linked to important functions in the host. Alterations in its composition and/or its by-products, causing loss of homeostasis, contribute to dysfunctions in other organic systems, including the skin, hence suggesting a gut-skin relationship. The oral administration of probiotics, widely associated with improved intestinal health, can act through an immunomodulatory response, both locally and systemically, presenting itself as potentially beneficial in inflammatory skin diseases such as atopic dermatitis. Traditional kefir, consumed for centuries as a health-promoting natural food, has its biological activity attributed both to the presence of a complex microbiota and to the action of the metabolites released during fermentation. The biological activity of kefir has been demonstrated in part by its ability to positively impact the intestinal microbiota, mainly based on animal models and in vitro, thus providing limited information. The nutritional and microbiological value of kefir makes its application as a probiotic in the gut-skin relationship a topic of of significant interest. This review aimed to explore the impact of probiotics as regulators of the gut-skin axis, focusing on the current knowledge of kefir as a health-promoting food. Keywords: kefir, probiotic, gut-skin axis, skin health, atopic dermatitis
Single versus mixed edge activators in caffeine-loaded transfersomes: physicochemical and cytotoxicity assessment
Authors: Guerreiro Íris , Fernandes Ana Sofia , Rosado Catarina , Pereira-Leite Catarina , Rodrigues Marta
Published: February 2022

The performance of transfersomes as nanovesicular systems to enhance the skin permeation of bioactive compounds may be modulated according to their composition of edge activators (EAs). Vesicle size, deformability, and encapsulation efficiency can be altered when using nonionic surfactants as EAs with opposing hydrophilic-lipophilic balance (HLB). Thus, this work aimed to assess the impact on the physicochemical properties and the in vitro cytotoxicity profile of transfersomal formulations composed of single or mixed EAs, with opposing HLB values. Transfersomes made of single or mixed nonionic surfactants (Tween® 80 and/or Span® 80) were prepared in the presence and absence of caffeine, used as a model hydrophilic compound. Single or mixed EAs-containing transfersomes displayed promising physicochemical properties for cutaneous applications and were found to be stable for one month of refrigerated storage. Moreover, all transfersomal formulations were compatible with a keratinocyte cell line upon 24 h treatment. Altogether, these preliminary data suggest that the use of mixed nonionic surfactants as EAs may be further explored to modulate the performance of transfersomes as skin permeation enhancers. Keywords: Vesicular systems, nanotechnology, nonionic surfactants, caffeine
La violencia contra la mujer como lacra global
Authors: Sanz Caballero Susana
Published: February 2022

El trabajo hace una crónica de las manifestaciones de violencia contra la mujer detectadas por la Relatora Especial de Naciones Unidas sobre la violencia contra la mujer en las visitas oficiales realizadas entre 2015 y 2020. Las visitas cubren países de los cinco continentes y permiten diferenciar dos grandes grupos de casos: los de violencias que se repiten en todos los países visitados y los que son específicos de la cultura, religión y tradiciones dañinas de una determinada área geográfica. Los tipos de violencia que se repiten en todoslos países son la violencia doméstica, la sexual, el tráfico de mujeres y el feminicidio. Entre los casos particulares está la violencia en procesos de divorcio y sucesión en Israel, el acoso online en Reino Unido, la zina en Afganistán, la poligamia en Palestina, la violencia en el seno de las pandillas en Honduras, la ablación en Sudán, etc. El artículo indica la necesidad de un compromiso colectivo, una toma de conciencia, una labor de educación y formación, un cambio social, político y económico así como la necesidad de colaboración de todos los actores involucrados, empezando por las autoridades públicas pero siguiendo con la sociedad civil, empresas, centros educativos y sanitarios y las familias. Las medidas que se adopten deben ser de carácterlegislativo, administrativo, social, educativo, económico y político para ser efectivas.
Género y políticas públicas en América Latina
Authors: Sotomayor Gil Yudith de la Caridad
Published: February 2022

Una de las problemáticas transversales en el escenario latinoamericano es la cuestión de las políticas públicas con enfoque de género, que en un clima de implementación de programas gubernamentales, donde aún es insuficiente la solución a problemas de discriminación de mujeres y hombres, se agudiza en el marco de la COVID-19. Cada vez más se limita el acceso a recursos, educación, relaciones de poder, entre otros, a pesar de la diversidad de políticas institucionalizadas existentes en la región que deberían garantizar la equidad de oportunidades y la solución a las diferencias sociales. Es por ello, que el presente trabajo se centra en explicar el desarrollo de las políticas públicas en América Latina, haciendo énfasis en algunos países donde subsisten dificultades en este sentido. Se utilizan técnicas como la revisión bibliográfica y documental, Dentro de los métodos están el hermenéutico para desde el análisis de contenido establecer la estrategia extensiva, como parte del componente del criterio de cantidad-calidad, el cual permite desde la comprensión y la explicación llegar a la interpretación que afiance y redescubra el carácter objetivo de la información, a partir de la construcción de los datos teóricos y método de caso (nivel empírico). De esta forma se brinda un análisis que permite repensar las distintas políticas públicas para revertir la situación de discriminación de género y favorecer condiciones que posibiliten la equidad social en ambos sexos.
Afonso Arinos e o Sertão
Authors: Neves Zanoni
Published: February 2022

As origens rurais de Afonso Arinos explicam a essência de sua obra literária. Em linhas gerais, Arinos inclui-se no movimento literário denominado regionalismo, que deita raízes no romantismo de Franklin Távora e de outros autores de mesma orientação. Em seu livro Pelo sertão, obra seminal da literatura brasileira, Arinos bebe na fonte das classes populares: a linguagem, os temas, a mitologia, os personagens (tipos regionais), são inspirados em suas vivências no Município de Paracatu [MG], onde nasceu e onde sempre viveram parentes próximos. Outro traço marcante de sua literatura é, sem dúvida, o cerrado com sua fauna e flora, bioma onde se localiza sua cidade natal.
Ordenamento do território e avaliação de impacto ambiental
Authors: Argollo Ferrão André Munhoz de
Published: February 2022

A ideia de Ordenamento Territorial como instrumento de planejamento e gestão do território é um processo em desenvolvimento, cuja prática visa organizar o uso e a ocupação do território conjugando objetivos específicos para os diferentes níveis territoriais. A proteção e a gestão do ambiente em consonância com a organização física do território constituem domínios distintos em estreita inter-relação, essenciais para um desenvolvimento equilibrado e sustentável. A Avaliação de Impacto Ambiental e o processo de licenciamento ambiental podem ser considerados como uma prática de ordenamento territorial. No Brasil há que se percorrer um longo caminho para o uso efetivo do ordenamento territorial como instrumento de planejamento, não só no âmbito de atividades setoriais, tal como o licenciamento ambiental, mas como uma política de Estado no intuito de reduzir as desigualdades territoriais.

Authors: Trofymchuk Olexander , Zelensky Kyryl , Pavlov Vladimir , Bovsunovska Katerina
Published: February 2022

Issues related to the melting of the polymer mixture in cylindrical channels are considered. The peculiarity of the problem solved in this work is the presence in the channel of two-phase flows of a solid-liquid mixture under the influence of heating the outer surface of the cylinder and dissipative forces arising from friction of the mixture against the walls of this channel. The problems of heating the mixture, melting the polymer and determining the velocity of the phase transition boundary in the conditions of a mobile solid mixture due to the rotational motion of the mechanism that feeds the mixture into a cylindrical channel are considered. Mathematical models of certain processes are systems of differential equations with partial derivatives of mathematical physics; the corresponding boundary value problems are solved using numerical-analytical methods, which made it possible to obtain solutions in quadratures. The results of computer modeling of the developed algorithms are given.
Recurrent least square method for estimation of varying parameters
Authors: Spectorsky Igor
Published: February 2022

In this paper, linear object yt=a1y1+...anyn+b1u1+...bmym+δ is considered. The aim is to estimate the object parameters with an assumption that they are changing linearly: ai=ai,0+ai,1t (i=1,2,...,n), bj=bj,0+bj,1t (j=1,2,...,m), δ=δ0+δ1t, parameters ai,0, ai,1 (i=1,2,...,n), bj,0, bj,1 (j=1,2,...,m), δ0, δ1 are assumed to be constants (almost constants during long time). For this object, the recursive least square (RLS) method is generalized. Provided examples show that the obtained RLS generalization gives higher precision (in comparison with the classical RLS method) for a case when parameters change with constant (almost constant) speed during long time. When parameters change unpredictably, the precision of the proposed RLS generalization is worse then the precision of the classical method, but it is still high.

WHAT THEY SAY AND WHAT THEY DO: COMPARING DESTINATION MARKETING ACTIVITIES RELATED TO MOVIE TOURISM IN CROATIA’S ZADAR COUNTY
Authors: Furčić Martina , Pranić Ljudevit
Published: February 2022

Purpose – While influence of movies and television on destination image and tourist destination choice is well documented in tourism literature, understanding of the perceptions of destination marketers in movie locations remains an emerging area of inquiry. Consequently, the objectives of this study are: (a) to assess the perceptions of key destination stakeholders regarding the level of integration of movie-induced tourism and destination marketing after a movie's release, and (b) to compare their perceptions to what can actually be observed, in a relatively popular movieshooting destination such as Zadar County (ZC), Croatia. Methodology – Using the Hudson and Ritchie (2006a) model for exploiting movie marketing opportunities, this study employs multimethod research, combining interviews and observation. First, 10 representatives of the tourism and movie industries in ZC are interviewed about the following four factors: movie-induced tourism, marketing activities, branding, and stakeholder involvement. Second, seven tourism-related websites in ZC are analyzed for presence and quality of the movie-related promotional content. Findings – Interviews reveal that key stakeholders (1) embrace the notion of movie-induced tourism, (2) find movie tourism to be well integrated into destination marketing activities, (3) believe that movies are an integral part of ZC's place branding strategy, and (4) perceive that tourism and movie stakeholders actively and systematically collaborate on advancing the movie tourism. However, website content analysis reveals exactly the opposite. Contribution – Theoretically, this research sheds light on the destination marketers' perspectives in regards to movie-induced tourism. Practically, it offers insights on how to tap the potential benefits of movie tourism.
GEOHERITAGE AND TOURISM – OPPORTUNITIES FOR GROWTH
Authors: Grofelnik Hrvoje
Published: February 2022

Purpose – Contemporary tourism in many developed destinations relies on natural resources, many of which can be directly valorised as tourist attractions. Within natural resources, geoheritage (geological heritage) consists sites or areas of geological features with significant scientific, educational, cultural or aesthetic value. Despite its multiple values, the attractive geosites and their valorisation in tourism are still insufficiently covered. Methodology – This paper, aims to present the state of the art in a form of a research overview of geoheritage valorisation in tourism by analysing the WoSCC database. The results of overviewing 171 scientific papers on keywords geoheritage and tourism are presented and interpreted in the form of qualitative and quantitative analysis, maps, tabular and graphical representations. To identify the main research links and streams between geoheritage and tourism the bibliometric analysis is carried out using VOSviewer software. Findings – The papers are classified and it is revealed an insufficient representation of research in the field of tourist valorisation of geoheritage. It is also notable the spatial inhomogeneity towards interest in geoheritage research. Contribution – The paper brings a research agenda for covering gaps in the further scientific research of the field. The research also points out some possible streams and framework for future geoheritage research that offers new opportunities for the growth of tourism as a responsible and sustainable industry.

Purpose – The article presents the results of a study evaluating the efficiency, benefits, and contribution to the sustainable development of destination of the Certification Leading Quality Trails – Best of Europe in the Czech Republic in Lužnice Valley Hiking Trail. Methodology – The cost-benefit analysis was used for the evaluation of the efficiency of the certification. HEAT (Health economic assessment tool) method was used for quantification of the economic benefits from improving health due to hiking activity on the monitored route. The evaluation of non-financial benefits was based on indicators of the sustainability of destination development in the economic, social, and environmental areas, and on the aspect of visitors´ satisfaction. Findings – The economic efficiency of the certification is low. However, the non-financial benefits of the certified trail are significant. The research showed the benefits of the trail certification in several aspects: the improvement of the quality of the tourist hiking trail led to greater satisfaction of tourists and their better experience. Another benefit is the increase of the image of the destination (Toulava). The certification of the trail contributed also to the sustainable development of the destination in all three pillars. Contribution – The investigation confirmed the importance and benefits of the trail certification. There was a significant improvement in the quality of the route and increased tourist satisfaction. This creates potential for further sustainable development of the destination and related services. Therefore, it is recommended that other hiking trails in the Czech Republic also undergo certification.

Purpose – The accelerated lifestyle has led to changes in the way of traveling. The development of technology and the internet has created the opportunity for online contact with people from all over the world, so we can say that traveling has not been this easy and affordable so far. People choose shorter trips, meet the locals, learn about their culture and customs. The paper looks for the benefits of using the Couchsurfing network and its aim is to present the motivation of respondents from former Yugoslav countries to use the network during travel, as well as to host travelers at home. Methodology – The questions for the questionnaire were acquired from the research done by Liu (2012), while the authors entered the offered answers based on a review of the Couchsurfing.com site. Couchsurfing users received online questionnaires via private message and through groups. The questionnaire was also sent through Facebook private messages and posted in private groups. Findings – Based on the results, it is concluded that the dominant motive for using Couchsurfing during the trip is to get to know the local population, culture and customs, as well as hosting and keeping company to travelers visiting this region. Contribution – The social contribution of this paper emphasizes the motives of the Couchsurfing users from the former Yugoslav countries for traveling and hosting travelers. New research can be expanded to the level of Europe or separated for the mentioned countries.

Purpose – The existence of accommodation capacity is an indispensable condition for carrying out tourist activities. Therefore, the purpose of this research is to find out the influence of accommodation capacity on the number of tourists, the number of overnight stays and the average stay, so as to highlight the importance of this indicator for the tourist potential of Calarasi County. Methodology – In order to analyze the influence of the existing accommodation capacity on the number of tourists, the number of overnight stays and the average stay, the simple regression model was used, so as to find out what percentage of the dependent variables is explained by the dependent variable. The Eviews program was used to create the simple regression model. Findings – Following the application of regression, we found out that in Calarasi County, 30% of the variation in the number of tourists is explained by the variation in existing accommodation capacity. There is also a weak link between existing accommodation capacity and the number of nights spent. Contribution – The present study focused on the influence of accommodation capacity on some indicators of tourist traffic, and the results could meet the decisions that local authorities could take regarding the support of accommodation units in the county.

Particularities of Exergy Analysis in Air Conditioning Systems
Authors: Prokhorov V. I. , Troyanchuk S. V. , Razakov M. A.
Published: February 2022

The paper examines two methods of choosing the initial reference point for exergy of the moist air flow. The first method is characterized by a zero exergy value at the current temperature and humidity of the outdoor air, which are variable both in daily and annual periods. Another is characterized by constant values of parameters of moist indoor air (its temperature and humidity in the room). A comparative study has shown the advantages of the second method: greater stability of values in air processing processes and their convenient presentation on exergy chart. However, it should be noted that this method provides a non-standard technical representation in which the entire energy flow is reduced to zero. The climatic information (temperature and humidity of the outside air) for numerical-analytical experiment has been used from official open sources. The city where the air conditioning system was supposedly installed is Stavropol. The research has been carried out in the summer and cold periods of the year. It is assumed that there are not installed any large heat sources in the room and the main heat sources appeared depending on the period of the year. Additionally, the air conditioning system was equipped with a recirculation line from the serviced room with a mechanical ventilator. The recirculated air entered the mixing chamber in the air conditioning unit which is reducing the consumption of heat energy in the cold season. There are the processes of air conditioning on the Ramzin's h–d-diagram for warm and cold operational modes of air conditioning unit, the air conditioning system under consideration.
Thermal Spring System Plumbing across a Major Normal Fault: Pah Tempe, Utah, USA

Published: February 2022

Faults, including their cores and associated fracture zones, can play an important role in controlling the flow of ground water. Pah Tempe Hot Springs at Timpoweap Canyon in southwestern Utah provides excellent exposures of the damage zone of a major normal fault and associated groundwater discharge. This includes numerous point discharges of ~40°C Na-Cl water into the Virgin River along a ~500 m stretch of the footwall damage zone of the Hurricane fault, part of the greater Wasatch-Hurricane fault system. An impermeable fault core and fine-grained rocks in the hanging wall impede cross-fault flow and force thermal waters to rise to the surface. The spectacular canyon-wall exposures permit an investigation of a fractured bedrock vadose zone as an analogue to subjacent aquifers. Photogrammetry (visual and infrared) enabled the mapping of discrete inflow locations, as well as permeable discontinuities in the canyon walls. Geochemistry, including reaction-path models, defined plausible chemical evolution pathways of thermal waters, whereas high-resolution geophysical surveys provided information on subsurface disruption and the depth to bedrock beneath Virgin River channel alluvium. The synthesis of these approaches indicates that permeable pathways in fractured carbonate rocks exhibit heterogeneous patterns. Some rock volumes contain abundant permeable fractures, bedding-plane partings, and solution cavities. Yet, within such volumes, one fracture may be permeable, whereas another only a few cm away may not. On a large scale (tens of meters), entire volumes of bedrock may be impermeable. Geophysical studies can shed light on gross fracture patterns in the bedrock aquifer but are incapable of showing which features accommodate flow. Patterns of permeability in the thick vadose zone may be the best predictor of subjacent flow paths in the aquifer. Thermal waters represent the leakage of deep brines or the mixing of Virgin River underflow with deep brines. Carbonate rocks exhibit self-organization where stochastic distribution of fracture apertures channel flow into wider features that channel additional flow. In turn, these features self-widen through solution weathering. By contrast, siliciclastic and basement rocks are not nearly as prone to dissolution. Thus, fluxes are partitioned into north-south fractures that will tend to have aperture in this east-west extending region. The results of this study help improve the conceptualization of flow systems near fault zones, and the methods employed may be a template applicable to the study of other systems.

It is excessively crucial for performing production match of parent-child wells automatically by using assisted history matching approach, especially considering the interwell interference scenario. We explored a new EDFM-AI (Embedded Discrete Facture Model-Artificial Intelligence) workflow by taking into account the multiple uncertainty parameters that were composed of fracture height, fracture half-length, fracture conductivity, fracture water saturation, fracture cluster efficiency, and natural fracture conductivity. The history matching algorithm implemented in this study is advanced machine learning model called XGBoost. It could overcome the issue that the proxy model is always imprecise due to the limited training sample data. Specifically, we established a field-scale reservoir model that includes parent-child shale gas wells with fracture hits in the Sichuan basin. By using this sophisticated workflow, two wells’ history matching results are excellent in terms of the inversed solution of the hydraulic fracture properties and natural fracture properties. And then, we perform the production forecasting for parent and child wells, respectively. Consequently, the results show that the best match value for estimated ultimate recovery (EUR) of parent well is 287.4 million cubic meters whereas the best match value for EUR of child well is 187.6 million cubic meters. The reliable reason is that effective fractured area of parent well is larger than that of child well. Besides, the natural fractures have a significant impact on the performance of shale gas wells with fracture hits observed, especially in the short-term production period.

Strong fluidized rock avalanches with various particle sizes are one of the typical disasters in the mountainous area of southwestern China. Statistical analysis on rock avalanche particles can help understand the traveling behavior, distance, and deposition of rock avalanche, which are useful for potential threat range prediction and disaster prevention. Rock avalanche deposit has more than one oblique slopes different in attitude. Image distortion will happen when particles on the slopes are projected to one plane. Area projection conversion coefficient Ki is applied in this paper to correct the distortion and improve the precision of the geometric dimension parameters of the rock avalanche particle. A rock avalanche (Aerzhai rock avalanche) with a volume of about 10×104 m3 took place in Longxi Township, Wenchuan County, China, on April 8, 2018. Being corrected by the coefficient Ki, the mean area and the standard deviation of the particles within different zones have been obtained, and we analyzed their changes in vertical and transverse directions. Here, we show that the mean particle area decreases by about 61.1% from the source to deposition region and area standard deviation decreases by about 37.4%. The deposition region shows a higher proportion of small crashed particles than the source region. The proportion of small particles gets larger with the longitudinal motion distance and lateral distance. For big particles’ significant potential energy-driving ability and inertia advantages, the longitudinal motion routes can be maintained, and inertia decreases as the particles get smaller, while small particles offset from the center area laterally. These statistical characters are easy to be ignored if projection correction is not performed.

Rock landslides are generally controlled by a series of discontinuous interfaces formed by damage to complex structural rock masses that is related to folds, faults, and shear zones, which provide potential failure boundaries. Based on a detailed case study, the authors illustrate that structural damage not only affects the 3D boundaries of landslides but also significantly controls the initiation mode. In this paper, six large landslides triggered by the 2008 Wenchuan earthquake (Ms 8.0) in the carbonate strata within two wings of an anticline are selected as examples. A detailed geological engineering investigation, rock mass testing, and rock mass quality assessment are performed. The results of the research show that landslides near the core of the anticline may be closely related to the geological strength index, while landslides far away from the core of the anticline are more likely to be controlled by the preexisting weak zone within the slope. In addition, the combination of structural planes and weak zones further determines the initiation mode. A comparison of earthquake-induced landslides with gravity-induced landslides reveals that strong earthquakes accelerate the process of geomorphic erosion by reducing the geological strength index (GSI) values of landslides. Finally, this study proposes that the damage to rock masses in complex tectonic environments is of great importance to assess the location, initiation mechanism, and mode of potential large-scale landslides caused by strong earthquakes.
Competitive Effects of Permeability and Gravity on the Drying-Out Process during CO2 Geological Sequestration in Saline Aquifers

Salt precipitation from the drying-out process has a profound effect on the well injectivity during the storage of carbon dioxide (CO2) in deep saline aquifers. Both gravity and reservoir heterogeneity have a significant impact on CO2-plume behavior and CO2 storage capacities. The collective effect of gravity and heterogeneity on the drying-out process by site-scale numerical simulation based on the Sleipner project had been investigated. Three site-scale permeability heterogeneous models and a fracture model had been built; simulation results showed that the gravity effect significantly increased the solid saturation at the injection well in the homogeneous model; changing the position of the injection well can change the distance that gravity can act and affect the amount of salt precipitation near the injection well. A novel conclusion is gravity and heterogeneity showed a mutual resistance relationship when considering the collective effect of gravity and heterogeneity on solid saturation. Gravity effects reduced the amount of salt deposited in the fracture model; at low CO2 injection rate, gravity force dominated CO2 flow; increased rock heterogeneity suppressed the production of salt precipitates; at high CO2 injection rate, viscous force dominated flow; and increased heterogeneity increased salt precipitation. This research is of important guiding significance for the design of site screening and injection schemes from the perspective of avoiding a large amount of salt precipitation and pressure build-up.

The purpose of writing this article is to examine the concept of improving the quality of Kaoru Ishikawa and its implementation in improving the quality of education. Quality according to Ishikawa is customer satisfaction and quality is not only product quality but also includes people, processes, and every aspect of the organization. The quality improvement effort made by Ishikawa is by implementing a Quality Control system. In this effort, Ishikawa recommends establishing a QC Circle and the use of basic quality tools, one of which is the Cause and Effect Diagram. This Ishikawa quality concept can be implemented in education, including: 1) Improving the Quality of Education Output through Quality Control; and 2) The basis for formulating a strategy to improve the quality of education based on cause and effect. The concept of Ishikawa quality improvement provides motivation for educational institutions to carry out good quality management, one of which is consistency in carrying out quality control through the formation of a QC Circle and the use of quality control tools, one of which is the Cause and Effect Diagram. Thus, educational institutions can improve their quality by knowing the root causes of the problems that occur and determining the appropriate quality improvement strategy.
