Los resultados arrojaron gran dificultad en la utilización de las competencias comunicativas para favorecer la integralidad del perfil profesional, permitiéndonos por medio de otras investigaciones crear un plan de mejora desde el pensum.
Consolidación de indicadores institucionales utilizando bodega de datos
Authors: Rosado-Gómez Alveiro Alonso
Published: December 2021

Las instituciones de educación superior en Colombia, deben reportar sus indicadores de desempeño a diferentes entidades estatales de vigilancia y control; esta obligación produce que las universidades tengan que almacenar y gestionar la información que producen y que es debe ser reportada. Generalmente los procesos administrativos y académicos, van acompañados de un sistema de información que está alineado con las necesidades de los usuarios finales y permiten tener los datos actualizados y disponibles, para ser consultados en cualquier momento y responder preguntas de un proceso en específico. Esta clase de sistemas dificulta el análisis estratégico de la información para la toma de decisiones, al carecer de consolidación de datos con otras fuentes que permitan evaluar los resultados organizacionales, desde diferentes puntos de vista. Esta investigación muestra la aplicación de la inteligencia de negocios en la construcción de una bodega de datos que integre la información institucional que se reporta y soporte la toma decisiones de la Universidad Francisco de Paula Santander Ocaña.

Authors: Enriquez-Valencia Cruz Elena , Urón-Castro César , Cuetia-Londoño Juliana Andrea
Published: December 2021

La presente revisión hace una exploración profunda y actualizada sobre el tipo de fibra muscular y su asociación con las características de calidad de la carne en bovinos. Se ha demostrado a través de los años, que las características consideradas como calidad de la carne, especialmente la terneza, están asociadas a factores específicos del músculo como contenido de grasa, colágeno, sistemas de actividad proteolítica y tipo de fibra muscular. Cada tipo de fibra presenta distintas características funcionales, estructurales, metabólicas, químicas y morfológicas, las cuales pueden alterar los procesos bioquímicos post-mortem y consecuentemente afectar los mecanismos de terneza de la carne. En la actualidad, los últimos estudios biotecnológicos que incluyen proteoma e interactoma asociados a la bioinformática confirman este hecho, la terneza de la carne depende de la raza y las propiedades contráctiles y metabólicas específicas de cada músculo, propiedades las cuales, están incorporadas de acuerdo al tipo de fibra muscular.

Lo aquí expuesto, son la respuesta de diversos ensayos y pruebas a través del tiempo en diferentes cultivos, lugares y países, que resuelve en parte las necesidades del adecuado manejo de la fertilización Nitrogenada edáfica, en la producción de cultivos, estas experiencias son el motor de la agricultura de este nuevo siglo, amigable con el medio ambiente y sostenible para el productor.
Diseño y análisis experimental para determinar la porosidad de materiales adsorbentes compuestos
Authors: Pérez-Rojas Eduar
Published: December 2021

Los sistemas de refrigeración por adsorción que usan como fuente calor residual, dependen de la calidad del lecho adsorbente donde se utilizan sales anhidras cuya conductividad térmica y porosidad son bajas; por esta razón se impregnan con materiales como el grafito o el carbón activado. En este trabajo se aplicaron técnicas de diseño de experimentos para determinar cuáles de los factores involucrados en la preparación del material adsorbente generan un impacto significativo en la porosidad del material adsorbente, para ello se establecieron respuestas superficiales y una región óptima donde el material tuviera una porosidad alta con un mínimo costo de producción, esto tiene gran implicación en la simplificación del desarrollo de procedimientos para producir materiales adsorbentes compuestos de mayor eficiencia. Se determino que los materiales con mayor porcentaje de material de impregnación mejoran las condiciones de la porosidad.
Células asesinas naturales con el receptor de antígeno quimérico (CAR-NK)
Authors: Vázquez Rodríguez Adrián , Mendoza-Rincón Jorge Flavio
Published: December 2021

Una de las herramientas más novedosas en inmunoterapias adoptivas contra leucemias y tumores malignos es el uso del receptor de antígeno quimérico “CAR”. El receptor CAR ha sido ampliamente utilizada en células T (células CAR-T) potenciando su eficacia en el reconocimiento y eliminación de tumores, obteniéndose a la fecha terapias basadas en esta tecnología. No obstante, las células CAR-T llegan a repercutir negativamente en la salud del paciente, presentando el síndrome neurológico de efecto inmune asociado a células (ICANS) y el síndrome de lanzamiento de citocinas (SLC). Como consecuencia, el paciente necesita ser hospitalizado durante la terapia. Además, el coste de manufactura y terapia es elevado, siendo una tecnología limitada a un sector muy bajo de la población. En este trabajo, mencionamos el empleo de una terapia emergente de células asesinas naturales (NK) con el receptor CAR (CAR-NK), que cuentan con muchas ventajas por encima de las células CAR-T. Las células CAR-NK conservan su capacidad citotóxica en contra de tumores gracias a su acción dependiente de receptores activadores e inhibidores, por lo que el receptor CAR, solo estimula sus habilidades y persistencia. Sumado a esto, el coste de una terapia de células CAR-NK podría resultar redituable debido a la capacidad de las células CAR-NK de eliminar múltiples células tumorales sin generar daño colateral en el paciente. Aquí analizamos las características de los múltiples receptores CAR y los fenotipos de células NK que han sido utilizados durante múltiples ensayos (NK-92, células NK de sangre cordal y periférica, y células NK iPSC).

Cross-reactivity of each fraction among cereals in children with wheat allergy
Authors: Takei Mari , Saito Akemi , Yanagida Noriyuki , Sato Sakura , Ebisawa Motohiro
Published: December 2021

Background: Cross-reactivity between wheat and other cereals is an
essential issue in the management of wheat allergy. Few studies have
reported in vitro cross-reactivity in immediate-type wheat allergy. This
study aimed to examine cross-reactivity of the three fractions
(albumin/globulin, gliadin, and glutenin fractions) among cereals in
children with wheat allergy. Methods: Sera from 128 children with
immediate-type wheat allergy were collected. We measured specific
immunoglobulin E (sIgE) levels against each fraction of wheat, barley,
and rye by using an enzyme-linked immunosorbent assay (ELISA).
Cross-reactivities of each fraction among wheat, barley, and rye were
examined via inhibition ELISA. Results: All subjects were sensitized to
all the fractions of wheat, and also those of barley and rye. The wheat
sIgE levels were significantly higher than those of barley and rye in
all the fractions (p ≤ 0.001) and were significantly correlated with
sIgE levels to them in each fraction (r = 0.887–0.969, p <
0.001). On inhibition ELISA, wheat inhibited the IgE binding to most of
the solid phases at the lower protein levels compared to barley and rye
in all fractions. Conclusions: In children with immediate-type wheat
allergy, sensitization to all the three fractions of wheat was observed.
In addition, they showed sensitization to barley and rye caused by in
vitro cross-reactivity with wheat in each fraction. When managing
children with wheat allergy, sensitization to barley and rye caused by
the cross-reactivities should be considered.
Necrotising Otitis Externa Antibiotic therapy complications: A retrospective cohort analysis
Authors: Ijaz Ali , Williams Emma , Cole Joby , Watson Glen
Published: December 2021

Introduction: Necrotising otitis externa (NOE) is a serious, progressive
infection of the external ear canal. If untreated, it can invade into
temporal bone, skull-base and surrounding tissue resulting in cranial
nerve palsies, neurological infections and death. Patients present with
unremitting, severe otalgia, otorrhoea and oedematous ear canals
containing granulation. Surgery has a limited role; the mainstay of
treatment involves a long course of intravenous antibiotics. Currently,
there is no data on the complications of antibiotic treatment for NOE.
This project aims to provide evidence on the nature/frequency of severe
treatment-related complications requiring a change in antibiotic regime.
Methods: A retrospective 5-year cohort analysis was performed on 64
patients who were treated for confirmed NOE with intravenous antibiotic
therapy. Clinical notes, blood results and antibiotic prescriptions were
documented and analysed. Results: Average duration of treatment was 11
weeks (range=38 weeks). There was an average of 2.1 antibiotic regimes
per patient with 10 cases requiring inpatient admission due to
treatment-related complications. 63% of treatment changes were directly
related to adverse effects of intravenous antibiotics. Drug
allergy/intolerance (n=18) and clinical deterioration i.e. Lack of
symptomatic improvement and/or worsening inflammatory markers (n=18),
were the most common reasons for antibiotic change. Neutropenia,
deranged liver function tests and acute kidney injury were also
recognised adverse effects of treatment. Conclusion: This study provides
the first evidence on the notable frequency of antibiotic-related
complications in NOE patients. Larger, multicentre studies are required
in the future to validate our findings and will better inform both
clinicians and patients of the risks of treatment.
Methodological approaches to morbidity forecasting in military educational organizations

Published: December 2021

The article discusses aspects of the application of extrapolation and factor approaches to epidemiological forecasting, outlines the limitations and features of their application in relation to the prediction of morbidity.

It is shown that when using an extrapolation approach, it becomes possible to predict the most likely numerical characteristics of morbidity in a certain time perspective. At the same time, the accuracy of the obtained forecast depends on the length of the time series and the type of long-term dynamics of morbidity. In turn, the trends formed by the results of forecasting artificially level the critical levels of morbidity that characterize individual periods of time and are fundamentally important for understanding the real picture.

The factor approach is based on the prediction of morbidity levels using a certain set of factors. The difficulty of using the factor approach is noted due to the stochasticity of the epidemic process.

Based on the results of a retrospective epidemiological analysis of the personalized morbidity of cadets of the Military Medical Academy, the heterogeneity of military contingents in susceptibility to acute respiratory infections of the upper respiratory tract is shown.

From the standpoint of the academician V.D .Belyakov’s et al. theory of the parasitic systems self-regulation, the conclusion is made about the expediency of using a factor approach for epidemiological forecasting of morbidity in organized collectives. It is proposed to use the state of individual resistance as one of the main factors determining the epidemic well-being of organized collectives.

The results of the development and testing of an electronic database that allows epidemiological surveillance of the morbidity of trainees and its linear prediction are presented.

Authors: Rudakova A. V. , Vilnits A. A. , Kharit S. M. , Lobzin Yu. V.
Published: December 2021

Generalized forms of invasive meningococcal desease (IMD) are very dangerous because they have a high mortality rate.

The aim of the workwas to assess the cost-effectiveness of meningococcal vaccination of infants with the 4-valent MenACWY-D conjugate vaccine in the Russian Federation.

Material and methods. Cost-effectiveness analysis based on epidemiological data for the Russian Federation was carried out by a modeling method with a horizon of 80 years from the position of the healthcare system and taking into account the social perspective. Vaccination costs were calculated on the basis of the registered price of the vaccine, including VAT, the costs of GFMI therapy and patient rehabilitation – based on the compulsory medical insurance tariffs in St. Petersburg for 2021. Indirect costs due to temporary disability of patients’ parents, disability of patients and premature death were estimated by the lost GDP. In the base case, costs were discounted by 3,5% per year, life expectancy – by 1,5% per year.

Results. Given the assumptions made, the average lifetime burden of a child’s illness is 17,556 million rubles. (no discounting). In the base case, the incremental cost per LYG from the payer perspective – 7,821 million rubles, and from the social perspective – 3,328 million rubles. Incremental cost per QALY – 5,350 million rubles and 2,277 million rubles, respectively. The most important factors that have a significant impact on the cost-effectiveness of vaccination are the incidence of IMD, the price of the vaccine, and the value of the discounting of costs and life expectancy.

Conclusions. Given the assumptions made, meningococcal vaccination of infants with 4-valent meningococcal vaccine can be considered as a viable option.

Published: December 2021

Utilizing X-ray crystallography, the crystal and molecular structures of 2,6-diacetylpyridine bis(phenylhydrazone) (L) were determined. The energetics of the intermolecular interactions in the crystal structure were assessed with computational methods, revealing that dispersion interactions are dominant. The basic structural unit of the crystal packing was revealed to be the herring- bone type arrangement of L molecules. Assignation of the IR spectrum of L with the aid of DFT calculations was performed. Furthermore, new reactions of L with CuBr2 in different solvents are described, which led to the synthesis of the mixed Cu(II)?Cu(I) complex with the formula [CuIIL2][CuI 2Br4] (1), and its structural characterization. In the complex cation, two molecules of tridentate N3 ligand are meridionally arranged in a very distorted octahedral environment of a Cu(II) ion. In [Cu2Br4]2-, the bromide ions are arranged in a trigonal- -planar geometry around each copper(I) atom. Finally, for ligand, 1, and the previously synthesized complex [CuL2]Br2, the thermal properties were examined. The thermal stability of the complexes were lower than that of the ligand and decrease in the order: L (250?C) > [CuL2]Br2 (221?C) > [CuIIL2][CuI 2Br4] (212?C). The differences in thermal stability of the complexes are due to differences in the packing efficacy of the constitutional ions.

Published: December 2021

A procedure and optical concept is introduced for ultrashort pulsed laser cleaving of transparent materials with tailored edges in a single pass. The procedure is based on holographically splitting a number of foci along the desired edge geometry including C-shaped edges with local 45° tangential angles to the surface. Single-pass, full-thickness laser modifications are achieved requiring single-side access to the workpiece only without inclining the optical head. After having induced laser modifications with feed rates of ∼1m/s, actual separation is performed using a selective etching strategy.
Narrativa e a questão mito história
Authors: Silva Guilherme Cavalcante
Published: December 2021

Este trabalho se ocupa de uma discussão sobre a relação entre mito e história na teoria narrativa de Ricoeur, em relação ao modo como a teologia tradicionalmente e contemporaneamente tem considerado esta questão. O artigo demonstra como a abordagem de Ricoeur oferece uma contraposição tanto ao projeto demitologizante de Bultmann como paradigma para o entendimento da narrativa bíblica, como para esforços teológicos recentes em separar o relato bíblico de qualquer caráter mitológico, atribuindo a este uma qualidade histórica interpretada sob o âmbito da historiografia científica. Sob esse cenário, Paul Ricoeur resgata a questão do mito ao questionar uma dicotomia dada por assentada entre mito e história. Tal empreitada é vista por Ricoeur como essencial para todo o projeto de sua teoria narrativa e possui implicações diretas para reflexões teológicas contemporâneas. O trabalho segue uma metodologia teórica de revisão bibliográfica a partir de textos de Ricoeur e outros pensadores como Vanhoozer, Stiver e Pellauer.
STRUCTURAL FEATURES OF A WATER INTAKE FACILITY FOR MOUNTAIN AND SUBMOUNTAIN RIVERS
Authors:   Azerbaijan Scientific-Research and Design-Prospecting Power Engineering Institute, Abilov Rashad
Published: December 2021

Introduction: The rate of urbanization is currently high. Therefore, it is important to use various elements and devices for water intake and water supply. Purpose of the study: We aimed to consider and analyze the structural features of a water intake facility for mountain and submountain rivers. Methods: In the course of the study, we used the synergistic research principle and statistical analysis. We analyzed the types of water supply networks at mountain rivers and identified the features of water intakes at water sources of this type. Results: A description of water intake features under flood conditions in the Amur Region, exemplified by the Bureya River, was obtained. The mountain rivers have an uneven runoff, which fluctuates not only throughout the year but also throughout the day. The water supply of the mountain and submountain areas shapes the idea of hydrological control over the regime of the mountain rivers. This paper will help to study changes in the average water inflow over the years and thus facilitate an accurate and detailed description of the water inflow characteristics in the Bureya reservoir when planning the water-energy modes of the hydroelectric power plant.

Authors:   National University of Architecture and Construction of Armenia, Sarukhanyan Arestak , Vermishyan Garnik ,   National University of Architecture and Construction of Armenia
Published: December 2021

Introduction: This paper studies the frequency with which hydrodynamic parameters change in the sudden expansion section of axisymmetric pressure flow, based on the boundary layer equations. Methods: The suggested method reveals the regularity of changes in the hydrodynamic parameters of the flow in the transitional area, making it possible to obtain a velocity profile in any cross-section under common initial and boundary conditions. Based on the general solutions, we studied the hydrodynamic processes occurring in the transitional area of the effective sudden cross-section expansion within the axisymmetric pressure movement, in the following cases: a) when the velocity is constant at any point of the inlet face; b) when the velocity is distributed along the inlet face according to the parabolic law. Our calculations were carried out for different values of the expansion factor. Results: Based on the results of the computer-aided experimental study, we obtained velocity diagrams along the length of the transitional area with constant and parabolic velocity distributions for fluid inflowing into the expanded section. We also determined the patterns of pressure distribution along the length of the relevant section.

History, theory, and court practice are the basis of judicial reform. If the Civil Procedure Code of the Russian Federation was created considering this with, but subsequent changes of the procedural law show the opposite. Changes of procedure in the appellate court are not an exception, and that is why for the last 10 years theoretical and practical problems of appeal proceedings have existed. The article aims to draw attention to the reasons of occurrence of these problems; mistakes made in the course of its solution; ways of error correction with due regard for experience of Russian civil procedure, achievements of the civil procedure doctrine, needs of Russian judicial practice; necessity of complex approach in reforming proceedings in the court of appeal instance.
NECESSARY (COMPULSORY) EVIDENCES IN CIVIL PROCEDURE
Authors: NIKITIN S.V.
Published: December 2021

In this article, the author examines the concept and procedural and legal significance of necessary (mandatory) forensic evidence. It analyzes the formulated by M.K. Treushnikov, who was the first in the procedural doctrine who paid attention to the legal obligation to use certain means of proof when establishing certain legal facts, the positive rule of admissibility of evidence, the positions of other authors on the issue of necessary evidence in civil proceedings. The rule of necessary (obligatory) evidence is considered as a special rule of judicial proof. At the end of the study it is concluded that the allocation of necessary evidence is carried out from the same content of factual data, reflecting the same fact, based on the peculiarities of their procedural form. Necessary evidence in its form is a specific type of a written document or expert opinion. Thus, the rule of proving the circumstances of the case with the use of necessary evidence concerns the form of evidence, beyond its content. The thesis is also put forward that necessary evidence, due to the specifics of the procedure for its formation, the presence of requirements established by law to its form and content, has a significant evidentiary value.
Role of Microenvironment in Ovarian Tumourisation
Authors: Khalikova L. V. , Shevlyuk N. N. , Gantsev Sh. Kh. , Khalikov A. A. , Khasanova I. R.
Published: December 2021

Background. Metastasis is a formidable complication of malignant neoplasms, with therapy not always effective in advanced malignancy. Metastasis is a multistep process involving the cancer cell detachment from primary tumour, intravasation, extravasation and invasion into the target organ. Early metastasis stages are well understood, whilst the impact of tumour microenvironment on the disease progression and advancement remains a matter of debate.

Aim. An immunohistochemical study of the adaptive and reactive properties of greater omentum with metastatic involvement in ovarian cancer.

Materials and methods. We examined greater omentum tissue samples from 40 patients with verifi ed stage 3a and b ovarian cancers. For light microscopy, samples were fi xed in 10 % formalin, dehydrated, paraffi n-embedded and stained with Mayer’s haematoxylin and eosin. Immunohistochemical assays used monoclonal antibodies against CD7, CD4, CD8, CD 68, VEGF, D2-40 and CD44 proteins. Statistical data analysis was performed with Statistica v. 7.0 soft ware.

Results and discussion. Analyses of the greater omentum tissues revealed cases of leucocyte-bank encapsulation of metastatic foci. Higher CD7+ and CD8+ cell counts were observed in encapsulation, possibly influencing the greater omentum reactive and adaptive properties. Higher CD44-expressing cell counts were also detected in greater omentum samples lacking encapsulation. Angiogenesis marker-expressing cells (e.g., VEGF and CD34) predominated in greater omentum tissues lacking leucocyte-bank encapsulation of metastatic foci.

Conclusion. Events in tumour microenvironment may be indicative of a preserved or reduced organ adaptivity, the latter facilitating disease progression.

Published: December 2021

Background. Gastric cancer is the world 5th top malignancy, with treatment success largely conditioned by comorbidity. Patients with end-stage renal failure developed with chronic kidney disease could not expect a specialty cancer treatment before the advent of long-term haemodialysis.

Aim. A case description of successful perioperative therapy and surgery in a long-term haemodialysis patient performed by a multi-specialty team of oncologists and transplantologists.

Materials and methods. We case-illustrate surgical treatment options in a gastric cancer patient with long-term haemodialysis.

Results and discussion. A specialty oncological treatment of end-stage renal failure patients requiring long-term haemodialysis is a complex multidisciplinary task feasible in hospitals equipped for different haemodialysis regimens. The treatment plan should be laid out by a multi-specialty team, as chronic kidney disease influences the choice of the drug class, dosage and administration mode. Moreover, such patients need laboratory (control of acid-base balance, haemoglobin, electrolytes, creatinine and urea) and clinical (body weight, liquid balance, etc.) monitoring.

Conclusion. Perioperative management studies in gastric cancer and chronic kidney disease-comorbid patients under long-term haemodialysis is a promising area of combining eff ort in oncology and transplantation science. Further research is needed in this topic for data enrichment and analysis in complex comorbidity patients.
Morphometric characteristics of the sciatic nerve trunk structural components with a single introduction of cryconserved placenta against the background of acute aseptic inflammation in rats
Authors: Svyrydyuk R. V.
Published: December 2021

The study was carried out on 55 adult male rats. The dynamics of changes in morphometric parameters with a single administration of cryopreserved placenta against the background of acute aseptic inflammation in rats is presented. Thus, it was proved that a single administration of cryopreserved placenta against acute aseptic inflammation of the sciatic nerve trunk induced by a single intraperitoneal injection of λ-carrageenan led to a total change in the sciatic nerve trunk that reached its maximum on the 10th day with the reliable difference (р>0.05) and further reliable recovery on the 21st day. The term of 21 days after a single administration of cryopreserved placenta against the background of acute aseptic inflammation of the sciatic nerve in rats is sufficient to assess the final results of regenerative processes in the structure of the sciatic nerve damaged by the inflammatory process in the rat.

Aim. To estimate efficacy of mini invasive transcutaneous interventions in treatment of purulent septic complications of acute necrotizing pancreatitis. Material and methods. We analyzed results of treatment of 85 patients with purulent septic complications of acute necrotizing pancreatitis in whom mini invasive transcutaneous interventions were applied during 2014-2019. New onset of organ failure after operation, duration of intensive care treatment, postoperative complications and mortality rates have been studied. Results and discussion. Transcutaneous punctions and drainages were definitive methods of treatment at 74.1 % of patients with infectioned pathological lesions, at 25.9 % of patients – as a stage for preparation for open necrosequestrectomy that promoted to reduce postoperative mortality to 4.5 %. Conclusion. Transcutaneous mini invasive interventions are effective methods of step-up treatment of purulent septic complications of acute necrotizing pancreatitis, reduce necessary for wide laparotomic necrosectomies and reduce level of postoperative mortality.

Einn mest áberandi þáttur í góðum stjórnarháttum síðustu tvo áratugina hefur verið endurskoðunarnefnd, sem fer með hluta af störfum sem stjórn hafði áður á sínu borði. Endurskoðunarnefnd er m.a. ætlað það hlutverk að auka traust almennings á fjárhagslegum upplýsingum á almennum fjármagnsmarkaði. Gagnsæi og traust eykst ekki sjálfkrafa. Vandaðir og heiðarlegir starfshættir eru nauðsynlegir til þess að öðlast traust haghafa. Rannsókn þessi felur í sér spurninguna um hvort að endurskoðunarnefndir auki gagnsæi og traust á fjárhagsupplýsingum fyrirtækja. Greinin byggir á tveimur könnunum, annars vegar frá 2016 þar sem nefndarmenn endurskoðunarnefnda í einingum tengdum almannahagsmunum voru þátttakendur og hins vegar frá 2018 þar sem ytri endurskoðendur voru þátttakendur. Í greininni er fjallað um afstöðu og álit þátttakenda varðandi tilkomu endurskoðunarnefnda gagnvart gagnsæi og trausti m.t.t. fjárhagsupplýsinga. Slík rannsókn hefur ekki verið gerð áður á Íslandi. Tilgátur voru settar fram um hvað væri álit og afstaða hópanna varðandi tilkomu endurskoðunarnefnda. Niðurstöður eru m.a. að meirihluti nefndarmanna og ytri endurskoðendur telja að bæði gagnsæi og traust hafi aukist með vinnuframlagi nefndarmanna í endurskoðunarnefndum. Það vekur þó athygli í rannsókninni að niðurstaðan er ekki eins afgerandi og ætla hefði mátt, þ.e. stór hópur bæði nefndarmanna og ytri endurskoðenda telur að tilkoma endurskoðunarnefnda hafi ekki aukið gagnsæi og traust m.t.t. fjárhagsupplýsinga. Sú niðurstaða kallar á frekari rannsóknir, t.d. með því að spyrja fleiri hagaðila um álit þeirra á endurskoðunarnefndum og hlutverki þeirra í að auka gagnsæi og traust. Þetta kallar enn fremur á rannsóknir sem miða að því að meta markvirkni endurskoðunarnefnda í stjórnarháttarkerfi fyrirtækja tengdum almannahagsmunum.

Student Worksheet (LKPD) is a teaching material used by teachers to support the learning process. Containing material sheets and assignments that must be done, LKPD is also used to optimize student activities in learning. The scramble type of cooperative model is learning to practice the accuracy and speed of answering questions. Students must combine the right brain and the left brain. Not only that, students also have to guess quickly the answers to the questions that are available but are still in random conditions.
