Dinámica del consumo y aporte de nutrientes de fitoplancton, dominado por Microcystis sp. (Cyanophyceae) del lago de Amatitlán
Authors: Rodas-Pernillo Evelyn , Vasquez-Moscoso Camila A. , García Ovidio F.
Published: April 2021

El impacto antrópico cercano al lago de Amatitlán ha generado niveles altos de eutrofización que conllevan cambios en la dinámica del ecosistema. Uno de ellos es la proliferación de cianobacterias del género Microcystis que pueden llegar a ser perjudiciales para la fauna y flora de lugar e incluso para los seres humanos. Se presenta el caso de cultivo de un consorcio de fitoplancton, tomado directamente del lago y llevado al laboratorio en condiciones controladas, para medir su consumo y aporte de nitrógeno y fósforo, además de los cambios en los factores fisicoquímicos y la biomasa. Se observó la presencia de diatomeas del genero Nitszchia y cianobacterias como Dolichospermum, con una marcada dominancia de Microcystis sp. Se analizó el porcentaje de cambio en la concentración de nutrientes. Los resultados indican que hubo un aumento en las concentraciones de amonio, nitrato y nitrógeno inorgánico disuelto, mientras que disminuyó el nitrógeno total, el fósforo total y los ortofosfatos. Esto indica que hay aporte de nitrógeno inorgánico, consumo de fósforo y nitrógeno orgánico. El fósforo parece ser el nutriente limitante, ya que, al consumirse en un 90 % la biomasa empieza a decrecer.

Authors: Sam-Colop Berta
Published: April 2021

La enfermedad renal crónica (ERC) es una patología que se asocia a la diabetes y enfermedades cardiovasculares principalmente. Es la destrucción progresiva de unidades funcionales del riñón, hasta perder capacidad de filtrar sustancias tóxicas. Con el objetivo de contar con información y conocimientos epidemiológicos oportunos, que permitan contribuir a una adecuada orientación de acciones en salud pública, se llevó a cabo un análisis descriptivo de las bases de datos de morbilidad del Sistema Gerencial de Salud (Sigsa), Unidad Nacional de Atención al Enfer- mo Renal Crónico (Unaerc), y de mortalidad del Instituto Nacional de Estadística (INE), Códigos CIE10:N18-19. A partir de 2013 se agregaron casos de Unaerc a Sigsa; esto incrementó seis veces el número (601/4,099) entre 2012-2013; de igual forma se incrementó entre 2013/2018, 87 % (4,099/7,760) y entre 2008/2017 se incrementó 15 veces más. En 2018 el mayor número de casos se reportó en Guatemala, Santa Rosa, Petén y Escuintla. Las tasas de prevalencia más altas, fueron en Santa Rosa, Jutiapa, Petén, Guatemala, Escuintla y Quetzaltenango. El grupo de edad con mayor número de casos fue de 25 a 59 años. Entre 2008 y 2017, se documentaron 19,491 casos en estadio V. Durante los últimos 10 años, ha incrementado 56 % la mediana de fallecidos, siendo 2,085 casos anuales. La mortalidad fue mayor en los departamentos con clima cálido, con ocupaciones elementales y sin ninguna escolaridad. Es importante fortalecer el diagnóstico para la detección de estadios tempranos, además asegurar el tratamiento de diabetes mellitus y enfermedades cardiovasculares

Published: April 2021

El aguacate es un cultivo de gran consumo a nivel mundial, localizándose su lugar de origen en la región de la Sierra Nevada en California hace ocho a cinco millones de años. En Guatemala se ha reportado una alta diversidad genética mediante caracterizaciones morfológicas, pero debido al comportamiento de polinización cruzada e hibridaciones interraciales, estas caracterizaciones presentan complicaciones y no es posible detallar la riqueza genética total. Los marcadores moleculares son una herramienta útil para este tipo de estudios al estar exentos de efectos ambientales y enfocarse en las diferencias a nivel del ADN. Este estudio analizó la diversidad genética del aguacate nativo guatemalteco colectado en siete poblaciones ubicadas en ocho departamentos del país, empleando el marcador molecular AFLP. Los datos fueron analizados mediante los índices de estructura poblacional que permitieron detallar el grado de diversidad genética de la especie, la cual presenta un alto grado de diferenciación a nivel de individuos (Ht= 0.1933, Hw = 0.1872). Este resultado sugiereuna alta taza de migración, reflejado a través de la similitud genética entre las poblaciones (Hb = 0.0061)y resultando en un alto grado de mezcla de los materiales presentes en el país. La escasa estructura poblacional es atribuida al proceso de selección, al sistema de polinización cruzada, el intercambio de semillas y al proceso de domesticación al cual aún esta sometido el aguacate. Finalmente, se sugiere el resguardado del recurso fitogénetico, así como una caracterización agromorfológica complementaria para establecer una adecuada estrategia de aprovechamiento en programas de mejoramiento genético.

Published: April 2021

La enfermedad conocida como punta morada, es un problema que afecta la producción del cultivo de papa, tomate y otras solanáceas. Se han reportado pérdidas que alcanzan el 90 % en la producción del cultivo de papa. En ambos cultivos, dicha enfermedad se caracteriza por causar un enrollamiento en las puntas de las hojas con una marcada coloración morada, decaimiento temprano de la planta y tuberización aérea, en el caso de la papa. Como vector transmisor, se reporta al psílido Bactericera cockerelli.Como agentes causales, se han asociado el fitoplasma BTLVA y la bacteria CandidatusLiberibacter solanacearum, sin embargo, debido a la similitud en la sintomatología que generan ambos patógenos, es díficil precisar cual de ellos está implicado en la enfermedad. En Guatemala, existen reportes de la sintomatología típica de punta morada en las principales zonas de producción de ambos cultivos, pero se desconce el agente causal. La investigación se enfocó en determinar alguno de los dos agentes asociados a la enfermedad, en doce municipios del país productores de papa o tomate. Para ello, se realizaron amplificaciones de ADN con cebadores específicos para cada uno de los patógenos asociados a la enfermedad. Se determinó la presencia de ambos patógeno en el país. Se sugiere un monitoreo constante, mediante métodos moleculares, para un diagnóstico certero y evitar la diseminación de la enfermedad hacia zonas aún no afectadas. También se recomienda el uso de secuenciación genética, debido a los indicios encontrados sobre otros fitoplasmas asociados a la enfermedad de la punta morada.
Envenenamientos por mordedura de serpiente en Guatemala: revisión de literatura
Authors: Wellmann Irmgardt A. , Guerra-Centeno Dennis
Published: April 2021

El accidente ofídico es una enfermedad tropical desatendida que ocasiona un problema de salud pública en el mundo, siendo una de las principales causas de morbilidad y mortalidad en las áreas empobrecidas de América Latina. En Guatemala se distribuyen 23 especies de serpientes venenosas de importancia médica. La composición de los venenos es compleja y diversa, resultando en una variedad de manifestaciones clínicas. Los departamentos con mayor incidencia de ofidismo son Petén, Alta Verapaz, Quiché, Escuintla e Izabal. Estos accidentes afectan más a hombres que a mujeres, siendo la mayoría agricultores; el rango de edad más comprometido es de 10-19 años y principalmente ocurren en miembros inferiores. El tiempo medio que tarda la víctima en llegar al hospital es de 5.6 h, siendo el retraso en la atención médica, un factor de riesgo para severidad y mortalidad. Los servicios de salud en ocasiones no cuentan con recursos idóneos para atender a las víctimas, brindando tratamiento sintomático. Simultáneamente, el tratamiento empírico tiene gran aceptación, sin embargo, los resultados de investigaciones realizadas con algunas plantas de uso común en casos de ofidismo, concluyeron que no es recomendable su uso aislado en el tratamiento del envenenamiento. Dada la falta de información se debe promover más investigación sobre el ofidismo en el país, siendo indispensable la elaboración de una ficha de reporte obligatoria. Además, deben elaborarse guías de tratamiento e identificación de serpientes para uso del personal médico, incluyendo programas de educación a nivel comunitario.

"Be Strong; Know What You Need": A Narrative on Inclusive Leadership
Authors: Valeo Angela
Published: April 2021

Based on an in-depth interview with a retired school principal, this paper explores questions around what it means to practice inclusive leadership in an Ontario school board from the mid 1970s into the 21st century.  Using semi-structured interview questions, the investigation specifically sought to understand the practice of creating inclusive schools for students with disabilities.  A narrative style using found poetry was used to give voice to the interviewee.  Central to the practice was the need for a strong moral purpose and a vision of inclusion, as well as the ability to build relationships across parents, teachers, students, and other school staff.  Additional insights included the need for the sharing of knowledge among all levels of school personnel. Instructional leadership, formal decision making approaches, and legislative procedures did not appear to be as important in ensuring inclusion.Keywords: inclusion; inclusive leadership; disabilities; special education
A Continuum of Learning: Enhancing Connections Between Teacher-Candidates and Education Graduate Students Through a Narrative Framework
Authors: Mitchell Lisa A.
Published: April 2021

This paper was written to complement the book review; "What’s Your Story? A Book Review of Leah Fowler’s A Curriculum of Difficulty: Narrative Research in Education and the Practice of Teaching" (2006), which can also be found in this issue of in education. This paper challenges teacher-education professionals to consider the benefits of creating and facilitating meaningful mentorship opportunities between teacher-candidates and education graduate students. This paper discusses Fowler’s (2006) model for narrative inquiry and its relationship to the formation of teacher identity and explores whether or not this particular model can support the creation of sustainable and effective mentoring relationships in current teacher-education programs. Teacher-candidates and graduate students alike will both come to a “deeper understanding of the relationship among past, present, and projected senses of self” (Sumara & Luce-Kapler, 1996) as they engage in mutually beneficial, critically reflective learning practices. Purposeful construction of mentorship opportunities that honour the experiential stories of individuals may serve to further increase education students’ awareness of their dynamic position along a continuum of learning in both undergraduate and graduate contexts.Keywords: narrative research; mentorship; teacher identity
Administrators’ Lessons Learned: Considerations in Establishing Demonstration Classrooms
Authors: Gallagher Tiffany , Grierson Arlene L.
Published: April 2021

This paper presents the perspectives of some administrators whose school sites hosted demonstration classrooms that were implemented as part of a board-wide professional development initiative.  Administrators highlighted the challenges of balancing the competing needs of their school system with those of their individual school communities and identified: (a) the need for advance planning; (b) the importance of consistency and communication; and (c) the complexities of acknowledging the dual roles and responsibilities held by demonstration classroom teachers.  Demonstration classroom professional development programs may hold the potential to enhance teachers’ knowledge and skills.  However, this study found that effective implementation of such programs requires skilled administrative collaboration and coordination.Keywords: educational administration, demonstration classroom professional development programs, implementation
Poetic Consciousness in Pedagogy: An Inquiry of Contemplation and Conversation
Authors: Wiebe Sean , Margolin Indrani
Published: April 2021

In this paper we consider the kinds of pedagogical engagements a poetic consciousness might invoke. When we reflect on what it might mean to be poetically conscious in moments of teaching, learning, and connecting, what emerges is the possibility of integrating the classroom experience with the everyday of life; such poetically conscious teaching would make connections to the larger web of a person’s experience in the world. To inquire into this possibility, we share our contemplations on our scholarly and personal experiences with poetry, presenting it here as a dis(e)ruptive text in order to invite aesthetic modes of being within the interplay of language and self. Our conversations have evolved over 3 years and have created this in-between space of active disclosure, where, we argue, poetry has offered dis(e)ruptions that celebrate the variations we inhabit in our bodies, personalities, and creative works.Keywords: Poetic consciousness; pedagogy, contemplation; conversation; dis(e)ruptive text

Finding Courage in the Unknown: Transformative Inquiry as Indigenist Inquiry
Authors: Tanaka Michele
Published: April 2021

Educators often wonder how to respond purposefully to vexing issues such as ecological sustainability, social justice and holistic health and wellness. The search for useful ways of proceeding can be addressed through engagement in the process of transformative inquiry, a mode of inquiry for educators that resonates with indigenous views and ways of being. At its heart, the approach seeks to support preservice  teachers in their personal journeys towards decolonizing and indigenizing. Ultimately, these efforts ripple out to affect their future students and the institutions in which they learn, teach and, hopefully, inquire. Weaving poetry written from my own experience on becoming indigenist, with the work of scholars such as Manulani Meyer, Lorna Williams, Marie Battise, Shawn Wilson, and Gregory Cajete, I highlight salient aspects of transformative inquiry that can be particularly useful in changing the trajectory of both education and educational research: welcoming spirit, deep and generous listening, connecting to place, and finding courage in the unknown.Keywords: Transformative inquiry; indigenizing education; decolonizing research; teacher education; educational research
Fostering Remembrance and Reconciliation Through an Arts-Based Response
Authors: Dupuis Jenny Kay , Ferguson Kristen
Published: April 2021

This paper presents the results of study about an urban high school in Ontario that performed a stage play that portrayed the legacy of the Indian residential schools in Canada. We wanted to know the impact this arts-based response had on teachers and students. From the data that we obtained from focus groups, we identify four learning outcomes of the legacy project: reflection on knowledge and identity; fact-finding through the processes of respecting memory; using the arts to remember; and broadening perspectives: remembrance (memory), reconciliation, and memorialization. Our research can assist educators and researchers to implement an arts-based model that honours and respects residential school survivors and their families.

Objective. Main objective was whether the combination of C-Reactive Protein (CRP) and Alvarado Score (AS) increase the diagnosis accuracy of AS among 2-to-20-year-old patients with suspected acute appendicitis presenting to Emergency Departments. Materials and methods. This is a secondary analysis of prospective cohort study consecutively including all patients from 2 to 20 years of age attended for suspected acute appendicitis in 4 Spanish Emergency Departments during 6-month period. We collected demographic, clinical, analytic and radiographic, and surgical data. AS categories were retrospectively calculated as low (0-4 points), intermediate (5-6 points) or high (7-10 points). The cut-off levels were >0.5 mg/dl for CRP. The outcome was diagnosis of acute appendicitis within 14 days of the index visit. Results. A total of 331 patients with suspected of acute appendicitis (mean age 11.8 (SD 3.8) years; 52.9% males) were recruited. According to AS, 108 (32.6%) were at low risk, 76 at (23.0%) intermediate risk and 147 (44.4%) at high risk of acute appendicitis. One hundred and sixteen (35.0%) cases had confirmed histopathological diagnosis of acute appendicitis. The AUCs of ROC were 0.76 (0.70-0.81) for AS and 0.79 (95% CI 0.75-0.84) for CRP-AS being the difference statistically significant (p=0.003). The CRP for diagnosis acute appendicitis in low risk AS group had negative predictive value of 95.8% (95%CI 87.3-98.9) and likelihood ratio negative of 0.4 (95%CI 0.2-1.0). Conclusions. CRP-AS has shown to increase the diagnostic accuracy of AS for acute appendicitis. This approach may be useful to rule out the diagnosis of acute appendicitis in paediatric patients attended for abdominal pain suggestive of acute appendicitis.

Hybrid Congestion Sharing and Route Repairing Protocol for Bluetooth Networks
Authors: Tahir Sabeen , Aldabbagh Ghadah Abdullah , Bakhsh Sheikh Tahir , Said Abass Md
Published: April 2021

Bluetooth is a widespread wireless technology standard for limited wireless networks that permits Bluetooth devices to create a one-hop (piconet) or multi-hop (scatternet) network. During data transmission, a large number of links passing through a single master or bridge device may create congestion problems in a Bluetooth network. Therefore, routing in a multi-hop dynamic Bluetooth network, where a number of routing masters and routing bridges exist, sometimes create technical problems in a scatternet. Mobility and failure of routing devices disconnects the routing links and link reconstruction process consumes more resources that eventually decrease the performance. In this paper, Hybrid Congestion Sharing and Route Repairing protocol for Bluetooth networks” (HCSRR) is proposed. The objective of this paper is to provide an efficient technique for scatternet congestion avoidance and route maintenance. The proposed protocol is implemented and compared with most relevant protocols. From simulation results, it is observed that the HCSRR outperforms the existing protocols.
A Segment-based Tree Traversal Algorithm for Enhancing Data Gathering in Wireless Sensor Networks
Authors: Jassim Mohammad A. , Almobaideen Wesam A.
Published: April 2021

Wireless Sensor Networks (WSNs) are sink-based networks in which assigned sinks gather all data sensed by lightweight devices that are deployed in natural areas. The sensor devices are energyscarce, therefore, energy-efficient protocols need to be designed for this kind of technology. PowerEfficient GAthering in Sensor Information Systems (PEGASIS) protocol is an energy-efficient data gathering protocol in which a chain is constructed using a greedy approach. This greedy approach has appeared to have unbalanced distances among the nodes which result in unfair energy consumption. Tree traversal algorithms have been used to improve the constructed chain to distribute the energy consumption fairly. In this research, however, a new segmentbased tree traversal approach is introduced to further improve the constructed chain. Our new proposed algorithm first constructs initial segments based on a list of nodes that are sorted according to post-order traversal. Afterwards, it groups these segments and concatenates them one by one according to their location; thus, our proposed approach uses location-awareness to construct a single balanced chain in order to use it for the data gathering process. This approach has been evaluated under various numbers of sensor devices in the network field with respect to various crucial performance metrics. It is shown in our conducted simulation results that our proposed segment-based chain construction approach produces shorter chains and shorter transmission ranges which as a result has improved the overall energy consumption per round, network lifetime, and end-to-end delay.

The first experience of application of remote radiotherapy in combination with hyperthermia and electrotherapy (oncothermia) in the treatment of patients with primary gliomas of the brain of a high degree of malignancy
Authors: Solodkiy Vladimir , Panshin Georgiy , Shevchenko Tatyana , Izmailov Timur
Published: April 2021

High-grade brain gliomas are characterized by a rapid clinical course and a 2-year survival rate of 8-12%. Despite the improvement of methods of surgery, radiotherapy( RT), and systemic drug therapy, it is still not possible to significantly increase the overall and relapse-free survival in patients with this neuro-oncological pathology, and the combination of RT and CT with hyperthermic electrotherapy (oncothermy) (OT) looks like a promising method that helps to increase the effectiveness of special treatment.

At the same time, oncothermia does not cause brain edema and does not worsen the quality of life of neuro-oncological patients. At the same time, a possible alternative to further progress in improving the results of treatment of primary brain gliomas (WHO Grade III-IV) is not only to optimize the radiotherapy program, but also to combine standard methods of radical treatment with hyperthermic electrotherapy.

This article presents preliminary immediate results of treatment of 20 patients who received special treatment in the RSCRR with an assessment of the toxicity and safety of its implementation and with an assessment of the likely resumption of continued tumor growth 1.5 and 3 months after the end of treatment. In General, the data obtained indicate the safety of the developed method of special treatment of this category of neuro-oncological patients,

which confirms the results obtained in 28.09.2019 patent for an invention. However, for final conclusions, further clinical studies are required on a larger group of patients with longer follow-up periods, followed by a thorough analysis of the results.

Published: April 2021

Aim. To reveal the characteristic features of tumor growth after orthotopic (OT) and intraperitoneal transplantation (IT) of high-grade syngeneic ovarian carcinoma.

Material and methods. Twenty mature female Wistar rats were randomized into two groups of ten each. The first group – animals underwent OT of ovarian carcinoma (4,3×106 cells) under the membrane of the bursa of the left and right ovaries; the second group – animals underwent IT of the tumor (4,3×107 cells). The endpoints of the study included an assessment of the overall survival (OS) of rats in two groups, determination of the peritoneal cancer index (PCI) on autopsy, and ascites weight. Autopsy material was histologically assessed analysis by light microscopy after standard staining. Cytological examination of ascitic fluid was carried out.

Results. Median OS was 29 days and 21 days in the OT and IT groups, respectively (log-rank test, P = 0.0276). Autopsy did not reveal significant differences in total PCI (12.6 vs 13.6 in the OT and IT groups, respectively) and ascites weight (78.0 g in the OT vs 65.8 g in the IT group). The method of transplantation did not affect the tumor grafting, histological characteristics, the nature of intraperitoneal spread and the ascites volume. It should be noted that there was a greater volume of tumor lesions in the organs of the reproductive system of rats (ovaries, uterus with horns, paragonadal fat pad) in the OT group.

Conclusion. Both methods of transplantation allow to reproduce the advanced stages (III-IV stages) of epithelial ovarian carcinoma in women. OT requires more time and operating conditions. OT and IT can be used to solve various problems in fundamental and routine preclinical cancer research.
Fusulinid zonation of the Upper Carboniferous Kap Jungersen and Foldedal Formations, southern Amdrup Land, eastern North Greenland
Authors: Davydov V.I. , Nilsson I. , Stemmerik L.
Published: April 2021

New fusulinid data from the Kap Jungersen and Foldedal Formations in southern Amdrup Land, eastern North Greenland allow the establishment of a detailed fusulinid-based zonation of the Upper Carboniferous succession in the Wandel Sea Basin. The fusulinid fauna is quite similar to that of the Russian Platform, the Ural Mountains, Spitsbergen, Bjørnøya, and the offshore areas of the Barents Sea, and therefore the Greenland strata are confidently correlated to the these regions. The Kap Jungersen Formation and the lower part of the Foldedal Formation are dated as late early Moscovian to latest Moscovian in age. The locally more than 450 m thick Moscovian part of the succession comprises four fusulinid zones: the Profusulinella prisca – Neostaffella subquadrata Zone and the Citrinoides paraozawai Zone of early Moscovian age, and the Fusulinella bocki – Pseduofusulinella pulchra Zone and the Protriticites ovatus Zone of late Moscovian age. Lower and middle Kasimovian deposits, characterized by two fusulinid assemblages of the Obsoletes obsoletus – Protriticites pseudomontiparus Zone and the Montiparus paramontiparus Zone, are recognised for the first time in Amdrup Land. The thin lower Gzelian succession is represented by two fusulinid assemblages that definine the Rugosofusulina flexuosa Zone and the Daixina crispa – Rauserites stuckenbergi Zone. The youngest Carboniferous strata, belonging to the Orenburgian part of the Gzelian are characterised by an assemblage of the Schellwienia ulukensis Zone.
Mantle plumes and sequence stratigraphy; Late Maastrichtian- Early Paleocene of West Greenland
Authors: Dam Gregers
Published: April 2021

The sedimentary history of the upper Maastrichtian–Paleocene succession underneath the extensive Paleocene flood basalts in central West Greenland supports models for the generation of flood basalt provinces in response to rising, hot mantle plumes. The rise of the North Atlantic mantle plume was associated with deposition of at least three sedimentary sequences; each associated with incision of submarine canyons and valleys. Relative sea-level changes were caused by plumerelated tectonics and generation of sequence boundaries was in general associated with catastrophic sedimentation and very rapid development of sequences. As such the late Maastrichtian–early Paleocene sequences record a spectacular and significant but rare geological event.

В статье анализируются языковые единицы, обозначающие темп движения в русском и персидском языках. Информация о темпе присутствует у большинства глаголов со значением движения. Анализ показывает, что языковые единицы в явном или скрытом виде обозначают перемещение субъекта и объекта с нормальным, быстрым и медленным темпом. В семантике глаголов, обозначающих перемещение с нормальным темпом, выделяется информация о стандартном положении в пространстве, отсутствии или наличии средств перемещения, добровольном перемещении, характеристике шагов (размеренность, выделенность) и т.д. Глаголы, обозначающие перемещение с медленным темпом, передают информацию о перемещении с трудом, о физическом недостатке, перемещении относительно опоры и т.д. Глаголы, обозначающие быстрый темп движения, сообщают о перемещении в направлении удаления от субъекта и о среде перемещения, намерении попасть в цель, скорости, принудительном перемещении, о намеренном погружении в жидкость, о полном отрыве от поверхности двух ног одновременно и т.д.

In this work, the linguistic units denoting the pace of movement in Russian and Persian languages are subject to analysis. Information on the pace of movement is present in most verbs denoting movement. The analysis shows that linguistic units in explicit or latent form indicate the movement of the subject and the object with a normal, fast and slow pace. In the semantics of the verbs denoting moving at a normal pace, information is highlighted about the standard position in space, the absence of means of movement, the availability of means of movement, voluntary movement, characteristic steps (dimensionality, emphasis), etc. Verbs indicating movement at a slow pace transmit information about movement with difficulty, physical disability, movement relative to a support, etc. Verbs indicating a fast pace of movement report movement in the direction of moving away from the subject and the environment of movement, the intention to hit the target, speed, forced movement, intentional immersion in a liquid, complete separation from the surface of two legs at the same time, etc.

This study aims to determine the extent of the influence of Return On Assets (ROA) and Operational Costs on Operational Income (BOPO) on Market Share in Islamic Banks in Indonesia as measured using Third Party Funds.

This research was conducted using company publication reports from the first quarter or March 2014 to the fourth quarter or December 2018 for five years, namely the 2014-2018 period from Bank Syariah Mandiri, Bank Muamalat Indonesia, Bank BRI Syariah, Bank BNI Syariah, and Bank Mega. Sharia.

The statistical method used is panel data regression, with t test and f test. The t test is used to test the effect of the independent variable partially on the dependent variable. The f test is used to test the effect of the independent variables together on the dependent variable using the EViews9 system.

It can be seen from the results that have been partially tested that BOPO has a significant effect on Market Share because it has a significance value <0.05 (0.0005). Then for ROA does not have a significant effect on Market Share because it has a significance value> 0.05 (0.0546). Simultaneously, the BOPO and ROA variables both have a significant effect on Market Share with a significance value <0.05 (0.000000).

The predictive ability of these two variables on Market Share is 72.75% as shown by the amount of adjusted R2, while the remaining 27.25% is influenced by other factors that are not included in the research model.

 

Keywords : Return On Assets (ROA), Operational Costs on Operational Income (BOPO), and Market Share.

Published: April 2021

The research consisted in testing Polish sawn timber dedicated for construction applications made of pines (Pinus sylvestris L.) that grew in the Silesian Forestry Region, taking into account three parts of the log: butt, middle and top. The boards had the same cross section, a nominal thickness of 40 mm and width of 138 mm, typical for Polish structural timber. The mean nominal length of the boards under research amounted to 3500 mm. Each set was composed of 70 boards. Before the tests, boards were dried in an industrial drier until reaching the moisture content of 12%, and they were planed on 4 sides. First of all, the sawn timber was graded into strength classes, and their dynamic modulus of elasticity (MOE_dyn) was tested with a non-destructive method, with the use of a portable MTG device. The next step consisted in a bending test with four points of support, according to the EN 408 standard, and with the use of the TiraTest 2300 machine, in order to determine the global modulus of elasticity (MOE_EN-408) and the static bending strength, also referred to as modulus of rupture (MOR). Finally, the average growth ring width was determined for each board (PN-D-94021), as well as wood density according
to EN-408. The hereby paper presents the test results for all the tested sawn timber boards, taking into account the part of log that each board came from: butt, middle or top. The hereby paper presents the influence of density on the mechanical properties of wood, taking into account the location on the round timber. The analysis does not include the influence of the width of annual growth rings and the proportion of latewood on the wood properties under research.
