El programa de Ingeniería en Redes (IR) de la Universidad de Quintana Roo (UQROO) inició el proceso de actualización de su plan a principios del año 2020 mediante trabajo colaborativo presencial entre los profesores que conforman la academia de Ingeniería en Redes; sin embargo, ante la contingencia derivada del COVID-19, los miembros del programa educativo tuvieron que adaptarse al cambio de paradigma de colaboración en línea, implicando un impacto significativo en cuanto a su metodología de organización. Así, el nuevo proceso de colaboración en línea consistió en el uso de las herramientas ofrecidas por la Universidad como Microsoft Teams, Planner, SharePoint, OneDrive, Outlook y Office 365. En este sentido, el presente artículo describe la metodología de trabajo colaborativo no presencial para diseñar la reestructuración del nuevo plan de la IR de la UQROO. Hasta el momento se tienen avances significativos en cuanto a su actualización, teniendo la posibilidad de ser presentado ante el H. Consejo Universitario para su aprobación.

The B.S. in Network Engineering (NE) is one of the educational degrees offered at the University of Quintana Roo (UQROO). In the early 2020s, faculty in the Network Engineering Department at UQROO began revising and redesigning the curriculum through face-to-face collaborative meetings. However, because of the COVID-19 pandemic, faculty members were obligated to shift paradigm, transitioning to work under an online collaborative mode. This had significant impact on their use of organizational strategies and methodology. For instance, the new online collaborative paradigm consisted of using tool offered by institutional technology license (e.g., Microsoft Teams, Planner, SharePoint, OneDrive, Outlook and Office 365). This paper describes the online collaborative work methodology used to revise and redesign the new curriculum for the B.S. in Network Engineering. This methodology has allowed for obtaining significant progress in the proposal, pending the approval of the Honorable University Council (HCU).

Breastfeeding is a natural process, but often mothers do not succeed in breastfeeding or stop breastfeeding early. Therefore, mothers need help so that the breastfeeding process is more successful. Breast care is an action to care for the breasts, especially during the puerperium (breastfeeding period) to expedite the release of breast milk. Breast care is very important during pregnancy to breastfeeding. This is because the breast is the only producer of breast milk which is the staple food for newborns, so it must be done as early as possible. The assessment in this case study was conducted on a P3A0 mother. From the results of the examination, it was found that the breasts looked tense, the nipple areola looked dirty and the milk had not come out. From the results of further studies, the mother complained of lack of sleep because her baby often cried. Based on these complaints, midwifery care was carried out, namely postpartum breast care, guiding positions and breastfeeding techniques that were good and correct and KIE regarding nutrition in postpartum mothers. Routine breast care can accelerate milk production. The role of the midwife to support the success of breastfeeding in postpartum.

Authors: NALDAN Funda , SEÇKİN Selçuk
Published: June 2022

Cami, Erzincan’ın Refahiye ilçesine bağlı Yazıgediği köyünde bulunmaktadır. Giriş kapısı üzerindeki inşa kitabesine göre Bahriye Nazırı[3] Hasan Hüsnü Paşa tarafından 1893 yılında yaptırılmıştır. 1891 yılından önce caminin inşası için projesi Bahriye Nazırı Hasan Hüsnü Paşa tarafından hazırlanmış, ancak gerekli olan araç ve gerecin olmadığı 1891 yılında Nezareti- Umur-ı Bahriye (Deniz İşleri Bakanlığı) tarafından bildirilmiştir. Daha sonra cami bu köyde bir ihtiyaç olması üzerine 1893 yılında tamamlanmıştır. Cami dikdörtgen plan özelliğinde olup düz ahşap tavan ile örtülüdür. Dıştan kırma çatı ile örtülüdür. 16 adet ahşap ayak tarafından üst örtü desteklenmektedir. Orta bölümde bulunan ahşap ayaklar üzerinde bulunan yastıklarda ahşap oyma tekniği ile yapılmış madalyona benzer süsleme bulunmaktadır. Son cemaat yeri bulunmayan caminin kuzey bölümüne sonradan giriş mekanı eklenmiştir. Cami, beton harç ile sıvandığından duvar örgüsü görünmemektedir. Ancak beden duvarlarındaki sıva izleri ve dökülmelerden anlaşılacağı üzere kesme taş malzeme ile kaplanmıştır. Harim kapısı ve pencere sövelerinde de kesme taş malzeme kullanılmıştır. Güney yönde yer alan mihrap, sonradan yağlı boya ile boyanmıştır. Minber sonradan eklenen yeni bir unsurdur. Kuzeyde batı yönden merdivenle çıkılan kadınlar mahfili, doğu-batı doğrultuda uzanmaktadır. Caminin plan ve mimari özellikleri, Erzincan ilindeki cami mimarisi ile paralellik göstermektedir. Osmanlı Döneminde inşa edilen bu camiler küçük boyutlu, sade ve basit bir mimariye sahiptirler.

Yapılan çalışmada yapı hakkında, Başbakanlık Osmanlı Arşivi’nde bulunan belgeler değerlendirilerek ve yapının günümüzdeki durumu, plan ve mimari özellikleri değerlendirmeye alınmıştır. Yapının inşa süreci, inşa kitabesi ayrı başlıklar halinde incelenmiştir. Keşif defterinde bulunan projede yer alan plan, kesit gibi bilgilere çalışmada yer verilmiş olup mevcut cami ile benzer ve farklı özellikleri ele alınmıştır. Son cemaat yeri ve tabuthane bölümünün olmayışı, ahşap minarenin konumu, pencere ve ahşap taşıyıcı sayılarındaki farklılıklar dikkati çeken unsurlardır.

Erzincan iline bağlı Refahiye, Erzincan-Sivas karayolu üzerindedir. Refahiye, 1872 yılına kadar Osmanlı idari taksimatında “Gercanis” ismi ile anılmıştır. Gercanis, önceleri Kemah’a bağlı bir nahiye iken sonradan Erzincan Sancağına bağlanmış ve günümüze Refahiye kazasının merkezi olarak gelmiştir. Köyün ne zaman kurulduğu bilinmemektedir. Kayıtlarda köyün ismi “Pusans”, “Posans” olarak geçmektedir. Köy, Refahiye ilçe merkezine 25 km. uzaklıkta bulunmaktadır.

Günümüzde ibadete açık olan cami oldukça bakımsız bırakılmış ve restore edilmeye ihtiyaç duymaktadır. Caminin korunması, mimarisine uymayan eklentilerin kaldırılarak özgünlüğünün korunması gerekmektedir.

Published: June 2022

Background: Idiopathic granulomatous mastitis (IGM) is a rare inflammatory disease of the breast with unknown etiology. Clinico-radiologic findings can mimic breast cancer. Further pathologic evaluation to rule out malignancy is mandatory. Recognizing the severity of the disease is crucial to choosing the most effective therapeutic modality. The aim of this study is to evaluate clinical and radio-pathologic features of IGM, and the treatment outcome in a large series of IGM patients in Iran.Methods: The retrospective charts of 243 patients suspicious of IGM, between December 2007 and September 2017 were reviewed. Patients with confirmed diagnosis of IGM were classified into four grades of severity. Demographic information, clinical and radio-pathologic findings, severity and treatment outcomes were collected.Results: Overall, 224 patients were confirmed to have IGM. Breast mass and erythema were the most common clinical findings. Mammographic findings mimicked malignancy in 34%. Lobulo-centric non-caseating granulomas were the most common pathologic finding. Also, 61.5% of the patients had mild to moderate symptoms and 49.5% of them recovered completely by observation. In addition, 53 (25.9%) patients had severe symptoms and 30.8% of them were resistant to treatment. Conclusion: IGM is a diagnostic challenge. Its diagnosis is based on exclusion and a close cooperation between the clinician, the radiologist and the pathologist. Mild to moderate cases can be managed conservatively; however, severe cases may need further aggressive medical or surgical treatments.
An Inquiry into the Problems Concerning Filipino Values and Norms
Authors:   Cebu Normal University, Cebu City, Philippines, Benitez Jiolito
Published: June 2022

This paper inquires into the problems concerning Filipino values and moral norms. Based on the interviews with the social science and philosophy scholars and the youth leaders in the Philippines, the study identifies the following problems: Filipino identity, distortion and dysfunctionalization, manifold ambivalence, dissonance, false justification and misuse, cynicism, and decline of moral courage. Analyzed based on Hans Kelsen’s concept of validity and efficacy, the problems prove to be radical given that the purported Filipino values system is actually a chaotic constellation of competing and conflicting pre-colonial, colonial, and postcolonial normative paradigms. Distorted, ambivalent, and dysfunctionalized, Filipino values and norms fail to provide effective normative guidelines. The proposed antidote of moral and values education is bound to be futile in the face of a severely mutilated social conscience.
The Experiences of and Responses to Linguicism of Quebec English-Speaking and Franco-Ontarian Postsecondary Students
Authors: Jean-Pierre Johanne
Published: June 2022

This article explores the experiences of linguicism of Quebec
English-speaking and Franco-Ontarian postsecondary students and how
they respond to these experiences. Using Goffman’s theory of stigma and
a qualitative approach, this article presents findings that emerged from
interviews conducted between January and June 2014 in Quebec and
Ontario. Both Quebec English-speaking and Franco-Ontarian
participants report experiences of linguicism, which are fueled by certain
stigma theories. Participants in both groups use similar strategies to
avoid conflict, but diverge in their attitudes. The findings point to the
significance of provincial contexts and the need for further studies about
linguicism among official language minorities.

The article contains a computational research aimed at operational and capital expenses reduction at the existing atmospheric subunit of the combined crude oil distillation unit by changing the process diagram and optimizing the preflash K-1 column operating mode parameters. In order to reduce the K-1 column condenser heat duty, the supply of additional cold reflux to the upper tray of the column was proposed to organize. As a cold reflux the 5% mass. of the total crude oil flow entering the unit is expedient to use. At the same time, the superheated steam in the amount of 0.5% mass. per feedstock is proposed to introduce under the lower tray of the column for increasing the overhead IBP-100°C fraction yield. K-1 column process diagram variants with a different number of trays in the presence and absence of additional reflux and steam supply are also considered. Results analysis shows that K-1 column can operate stably in the design mode with half number of trays in comparison with the existing apparatus. The additional reflux and the steam introduction shows good results: the condenser heat duty is about 50% of the original one,what makes it possible to reduce its heat exchange surface by half, reducing the apparatus metal consumption; the products fractionation sharpness increases - the overhead IBP-100°C fraction yield increases by an average of 4%.

Published: June 2022

In the article, the author analyzes the conditions of traps and deposits formation on the Nepsko-Botuobinskaya anteclise to clarify the factors affecting the productivity of deposits, affecting on the way of fluid migration to potential areas. The tectonic factor played a special role in the formation of traps and deposits. Also, part of the depositsis controlled by the lithological factor. All this causes the variety of traps currently available. The author considers the geological structure of the anteclise from the point of view of paleotectonics and provides diagrams of the types of deposits in the territory, as well as shows schematically the faults along which further migration of fluids is possibleto nearby territories. The widespread development of fault-block tectonics has a direct impact, both positive and negative, on the development and exploration of deposits associated with tectonic elements.

Potato is important for food security in developing countries such as Ethiopia. The purpose of this study is to evaluate the contribution of varied fertilizers to potato yields at Basketo Special Woreda, Gamogofa Zone, Ethiopia. To attain this objective, a generalized linear mixed model was used to differentiate the factors that affect the marketable yield of potatoes by considering variability within three replications. In addition, this study used the Kolmogorov-Smirnov test to check the goodness of fit tests of normal distribution. The collected data were analyzed using statistical software, SAS version 9.4. The mean of plant tallness, number of plants per plot, number of plants per slope, and number of tubers per slope were 73.65 (SD = 12.2), 155.2 (SD = 112.2), 3.23 (SD = 1.31), and 10.91 (SD = 3.15.2), respectively. The result reveals that 6% of variation existed in potato yield between plots, and the remaining 94% existed within plots. Apart from a linear mixed model, a random intercept model was applied to this data. The findings reveal that fertilizer types, number of plants per plot, and numbers of tubers per hill were significant at 5% level of significant. Thus, the expected marketable yield of potatoes decreased by 0.7819 tons/hectare when the number of tubers per hill increased by 1 unit. On the other hand, the expected marketable yield of potatoes has increased by 0.0175 tons/hectare when the number of plants per plot increased by 1 unit.

Ethiopia is the only country that produces teff (Eragrostis tef) in the world, but the production of teff is still low compared to other cereal crops. The main purpose of this study was to evaluate the impacts of organic and inorganic fertilizers on teff yield between 1995 and 2017 using an autoregressive distributed lag with co-integration approach. The Phillips Peron test and the Augmented Dickey-Fuller test for time series stationary checking and capturing serial correlation were used, whereas the Breusch Godfrey Lagrange multiplier and the cumulative sum test were used for determining the autocorrelation of residuals and the stability of coefficients. The result showed that the average yield of teff was 11.25 quintals per hectare, and the bounded F-test for co-integration among the variables does not show evidence of a long-run relationship between fertilizers applied and teff yield per hectare. The quantity of urea applied had a positive and significant impact on the yield of teff, and the quantity of di-ammonium phosphate (DAP) application had a negative impact in the short run. In conclusion, there was no co-integration between the yield of teff crops and fertilizer types such as urea and di-ammonium phosphate, which indicates that the quantity of urea fertilizer used for the production of teff has a positive relationship while the quantity of DAP fertilizer had an indirect relationship. Hence inorganic fertilizer like DAP is negatively correlated with the production of teff while organic fertilizer (urea) is positively correlated.

SCIENCE TEACHERS’ THEORY-BASED TEACHING: CONNECTING A LEARNING CYCLE MODEL TO A LESSON PLAN
Authors: Lee Insun , Park Jongwon , Yoon Hye-Gyong
Published: June 2022

This research examined theory-based teaching processes of science teachers to understand the mechanism by which theory and practice were connected. Four science teachers desgined lesson plans by applying the empirical-abductive learning cycle (EALC) model and modified lesson plans through a collaborative interview with the researcher. Data were obtained from lesson plans and interviews. Using the constant comparison method with open coding, data were analyzed to find out obstacles or facilitators acted in the process of applying the EALC model to design lesson plans and reveal the path through which theory and practice were connected. As a result, it was found that perceptive prejudice about the role and necessity of the EALC model was the main obstacle. The collaboration process helped teachers understand the EALC model clearly and deeply. The development of this cognitive understanding changed their prejudice about the EALC model and led them to reflect their teaching practices with the eyes of theory. Through this process, a separated state between theory and practice was developed to a connected state. With the belief that it is a good starting point for coordination between theory and practice, further studies are proposed.

A range of pedagogical learning theories has been proposed to guide science teachers' classroom teaching. This study presents the results of the development and use of an 18-item Arabic language rating scale survey to assess Omani teachers' (N = 400) views towards the application of selected pedagogical learning theories of potential use in their science classrooms. The current study was a quantitative approach following the survey design. Rasch analysis was used to guide the analysis of the instrument. The results suggested that one dimension was defined by survey items and item independence. Person and item reliability were acceptable. Analysis of category probability curves showed acceptable measurements from the rating scale. The Wright Map matched theory and so provided guidance for the future teaching of Omani science teachers. This study adds to the literature reporting the results of science education data collected from science teachers who teach for international use in general, and for Oman and Arab countries in particular. Perspectives and contributions of the study findings on improving science teaching and learning are discussed.

Findings. The Zhailma graben-syncline is not an independent structure of the rift origin. The formation of Zhailma is associated with the general evolution of the Sarysu-Teniz segment of the Devonian volcano-plutonic belt. The formation of the Zhailma graben syncline is associated with subsidence after ejections of significant masses of felsic magmatic material. Originality. The authors carried out a comparative analysis of the geological, geophysical and morphological data of the Zhailma structure with similar data characteristic of modern continental rifts. As a result of the analysis, it was established that the rift genesis of Zhailma remains controversial. This structure developed simultaneously with the Devonian volcanic-plutonic belt, and is genetically related to the processes of volcanism. The authors suggest that Zhailma is a volcanic graben-syncline. Practical value. Over a long period of studying the structure, an opinion was formed about the futility of the Sarysu-Teniz segment of the Devonian volcano-plutonic belt for the identification of industrial deposits. An exception was the Zhailma trough, which is a unique Famennian-Carboniferous sedimentary structure in terms of ore saturation, containing significant reserves of iron-manganese, barite-polymetallic and barite proper ores. In this connection, the authors consider it practically important to study the existing graben-synclines in the area of the Devonian volcano-plutonic belt in order to identify industrial deposits of the Atasu type.

Purpose. The purpose of the carried out granulo-chemical and mineralogical study, realised on barite of two veins 4 and 10 of Ain Mimoun deposit (Algeria), is the identification of the barite ore in order to be able to choose a reliable processing method due to its complicated structure. Methodology. The investigation was carried out by X-Ray Diffractions (XRD), Scanning Electron Microscope (SEM), X-Ray Fluorescence (XRF), particle size analysis and microscopic observations. Findings. Using the investigation devices, predominance of barite minerals was found at 51%, quartz in the vicinity of 34% and calcite at 9%, with a homogeneous distribution in all the fractions observed. Adding to that, the main compounds (oxides) present are SiO2, CaO, Fe2O3, Al2O3, P2O5, Na2O, K2O, TiO2, and MnO. Originality. For the first time the characterization of veins 4 and 10, in which the barite particles are embedded in silica, has been realised for the purpose of proving the possibility of their processing. Practical value. The obtained results confirm, on the one hand, that veins 4 and 10 are rich in barite and, on the other hand, barite particle release from silica particles is possible. Thus, we suggest, for a better and diversified use of the ore of the veins in question, the application of the flotation process, since the latter makes it possible to obtain high-quality concentrates, so it can be used not only in the petroleum field but also in the pharmaceutical and other industries.

Purpose. Research of the removal of arsenic by sulfiding from gold-arsenic containing concentrates of the Bakyrchik deposit. Methodology. To determine the composition of the samples, chemical and electron probe analysis were carried out; to determine the phase composition of materials, X-ray analysis was conducted. In order to predict the process of sulfidation of arsenic and its compounds in the range of 2982000 K, a thermodynamic analysis was performed. To establish the optimal conditions for the process of sulfiding arsenic and its compounds, studies were carried out to determine the effect of temperature and the consumption of elemental sulfur on the degree of sublimation of arsenic from gold-arsenic concentrate. The sulfiding roasting of the concentrate was carried out with elemental sulfur vapor coming from a new design evaporator with a mixture of gaseous nitrogen. Findings. The main minerals of the original concentrate are pyrite, marcasite, arsenopyrite, native gold and silver. Significant elements in the concentrate are, %: arsenic 2.93.1, iron 707.3, gold 40. It has been calculated by thermodynamic analysis that when the main minerals of gold-arsenic containing refractory ores and concentrates interact with sulfur in a neutral environment and in the range of 5001000 C, reactions of formation and removal of arsenic in the form of sulfides As2S3 and As4S4 occur. When a new design evaporator supplies elemental sulfur in a mixture with neutral gas and with an increase in firing temperature from 700 to 850 C at S : As = 0.35 : 1, the degree of sublimation of arsenic increases from 94.7 to 98.2%, with FeS2 : As = 1.3:1 from 94.0 to 99.5%. With an increase in the consumption of elemental sulfur vapor (with an increase in the S : As ratio from 0.35:1 to 0.6 : 1 and a temperature from 700 to 800 C), the degree of sublimation of arsenic from the gold-arsenic product reaches up to 99%. The condensed sublimes contained up to 98.599% As4S4 and As2S3, the dust caught in cyclones is close in its composition to the composition of cinder. Originality. A new technology for the removal of arsenic from gold-arsenic containing concentrates in an oxygen-free atmosphere in the temperature range of 700850 C with the removal and capture of arsenic sulfides up to 100% is proposed. The regularity of the degree of sulfidation of arsenic and its oxidized compounds by elemental sulfur vapors in a mixture with a neutral gas to As4S4 and As2S3 has been established. Practical value. The use of the new technology makes it possible to completely convert arsenic into sulfide forms which are environmentally friendly, convenient for storage, burial, or for use as antiseptics. The development can be used for processing arsenic-containing polymetallic ore materials.

Published: June 2022

Purpose. To study changes in the microstructure of metals after exposure to high-energy plasma jets formed by the cumulation of gas-dynamic flows in a conical target. To estimate the expected state of matter in a strong shock wave compression, taking into account the change in volumetric energy density at the moment of transformation of a solid body plasma into nuclear matter. Methodology. The technique of laser initiation of a profiled front of detonation waves in explosive charges and the corresponding profile of shock waves in materials, methods and techniques for measuring the dynamic parameters of shock-compressed substances are used. Findings. An experimental study on the physicochemical state of a substance that has been processed with extremely high pressures and temperatures during compression by converging shock waves in conical targets has been carried out. Scientific results of physical and mathematical modelling of converging shock waves are analysed. Originality. For the first time, the formation of symmetric plasma jets during gas compression in conical targets has been experimentally observed. For the first time, metallo-physical studies on the microstructure of cast iron and steel have been carried out. These studies were made after the action of high-energy dense plasma jets with a temperature of (2.52.8) × 106K and a pressure 1.12 × 1012 arising from the collision of the jet with a barrier. Iron-55 and copper-64 isotopes were found in the cast iron microstructure near the surface formed by the action of the plasma jet. The main components of the plasma jet were gaseous oxygen, nitrogen, argon, and atomic iron, copper and gold. The fact of formation of isotopes is the result of nuclear reactions. One of the main conditions for the implementation of such reactions is a dense high-temperature plasma. It is assumed that under the action of a strong shock wave in a conical target, in addition to the synthesis reaction, other nuclear reactions with heavy elements can be realized. The ideas about the expected state of matter in a compression shock wave are presented, taking into account the change in the volumetric energy density at the moment of transformation of a solid body plasma into nuclear matter. Practical value. The proposed technique for conducting experimental studies on a shock-compressed substance under the action of extreme temperatures and pressures in conical targets using laser initiation of chemical explosives is of practical importance. The idea of the expected state of matter in the shock wave is also important.

Published: June 2022

Purpose. Determining the interaction mechanism of discrete grains through material that binds them in a tool for abrasive material processing in the case of its loading with a tangentially directed cutting force. Methodology. Development and analytical solution to a mathematical model formulated on the basis of static equilibrium of an abrasive grain as a system element of tool grains bound with a material with excellent mechanical characteristics. Findings. A mathematical model has been developed and an algorithm has been formulated to analytically determine the stress-strain state parameters of a tool for abrasive processing of materials, which is loaded with a discrete cutting force, tangential to its working surface. The nature of the dependence of stresses and deformations on mechanical parameters, the quantity of grains and the material binding them in an abrasive tool, loaded with a unit tangential force, has been determined. Originality. The loading of the extreme grains leads to greater displacements, tangents of the shear angles of the material binding the grains. They decrease with increasing quantity of grain rows in the tool or with increasing quantity of grains to the nearest tool edge. Practical value. The distribution of interaction forces of grains and stresses in the material binding them has been determined. The found distribution allows one in the process of developing the tool and technology, in which it is involved, to comprehensively assess the influence of tangential load value of the tool working grain on its stress state and the material containing the grains. The determined stress state makes it possible to predict the number of loading cycles until the simultaneous rational wear of the grain and the destruction of that part of the material that contains it. The linear formulation of the problem makes it possible to take into account the mutual influence of the tangential loads of several grains on the stress-strain state of the tool as a whole.
