La gestión archivística en el Perú y la transformación digital
Authors: Martínez Suárez Carlos
Published: September 2021

La gestión archivística en el país, que ha tenido como base el desarrollo de normas y políticas, la profesionalización y capacitación archivísticas, y la materialización del procesamiento técnico archivístico, hoy en día se ve influenciada por la llamada transformación digital. Esta cuarta revolución industrial que, a su vez, debe considerar la política nacional anticorrupción, el buen gobierno y la transparencia y acceso a la información pública, se presenta como un gran reto que debemos asumir para continuar en el camino de una buena gestión archivística nacional.
Especificaciones ambientales y técnicas de seguridad para el diseño de la infraestructura física de un archivo central
Authors: Yturbe Mori Laura
Published: September 2021

En la mayoría de los archivos centrales, los documentos de archivo están siendo custodiados en lugares que no cumplen con lo mínimo para dar un buen tratamiento y custodia. Gran parte de estos son adaptados de espacios construidos para otros fines y, a veces, cuando existe la posibilidad de edificar desde cero, no cumplen con los requisitos. Este artículo indica elementos a considerar para la edificación de un archivo central, no solo enfocándose en su funcionalidad, sino que, además, expone las medidas adecuadas para la conservación y seguridad de los documentos.

In children and adolescents, psoriasis affects between 0.5% and 1.2% of the population. Currently, at least 80 chromosomal loci have been discovered that are significantly linked to psoriasis, and some of these loci are mainly linked to the onset of psoriasis in childhood. Pediatric psoriasis can be more difficult to diagnose due to an easier course of the disease, with smaller and thinner plaques, which are less scalable and with atypical manifestations. First-line therapy in psoriasis in both children and adults is represented by topical therapy. Treatment options for psoriasis in children and adolescents are largely off-label, with little data available on efficacy and safety.

Introduction. Infestation with the roundworm Ascaris lumbricoides is one of the most prevalent helminthic diseases belonging to the soil-transmitted helminths class. Infections are especially affecting children in tropical countries and low and middle-income countries but also may occur in developing countries where sanitation and hygiene are poor. We aim to present a case report to sound the alarm on this widespread pathology. Case presentation. We report the case of a 9-year-old boy with Down syndrome and duodenal stenosis admitted to our hospital with recurrent bouts of pancreatitis secondary to ascariasis. Child is living in poor sanitation conditions. The first episode of pancreatitis was at the age of seven. The abdominal ultrasound shows enlargement and heterogeneity of the head and body of the pancreas, and multiple images of "the strip sign" in the duodenum, suggesting the presence of Ascaris lumbricoides. Live worms were expelled several times. During the next two years, this child was admitted for similar episodes suggesting re-infection with the soil-transmitted helminths, repeated courses of albendazole were administered to the patient and to his close relatives contact. Conclusions. Ascaris lumbricoides infection is rarely a direct cause of mortality, but it contributes to overwhelming morbidity. Periodically repeated de-worming treatment and additional preventive measures such as improvements to water, sanitation and hygiene (WASH) could ensure high rates of eradication.

The history of icterus and neonatal jaundice has been recorded since the 17th century, when a French midwife first described jaundice (jaune) in twins. In 1940, Alexander Wiener and Karl Landsteiner discovered the Rh blood group, and they investigated the isoimmunization via antigen transfer across the placenta from the fetus. Other blood group systems implicated in isoimmunization were discovered between 1901 and 1965. Between 1940-1960, many studies have focused on the etiology of hemolytic disease of the newborn, on incompatibility in the Rh system, cholestasis, metabolic diseases, inhibitors of breast milk, and the association between prematurity and jaun-dice or extremely nuclear jaundice. It is the merit of AW Liley, in 1963, who described the diagram of the same name based on the level of bilirubin in the amniotic fluid and who performed the first fetal transfusions for fetal anemia. Last decades, non-invasive methods of diagnosis and treatment were described.

Introduction. Important abdominal distension can be a challenge for both paediatricians and pediatric surgeons. Case presentation. Here, we report the case of a 3-year old child admitted to Pediatric Surgery Department for significant abdominal distension, food refusal and abdominal pain. He underwent radiological investigations; conditions like congenital megacolon and mechanical obstruction were excluded. At hospital admission, abdominal distension was minimal, but it became severe after episodes of air swallowing. Sleep bruxism and behavioural changes appeared also. An abdominal computerized tomography scan and barium swallow tests showed important distension of the stomach with excessive gas, a small intestine and colon. On upper endoscopy - the urease test for Helicobacter pylori detection was positive and specific treatment was administered. In addition, a psychiatric evaluation was done because of behaviour changes. Aerophagia was suspected, and clonazepam treatment was recommended. Conclusion. This is an unreported case of association between Helicobacter pylori infection and aerophagia, which had a favourable outcome after antibiotherapy for gastritis and clonazepam for psychologic aerophagia.

Gastroschisis is a malformation of the closure of the anterior abdominal wall which has had a growing incidence in recent years. It is a borderline pathology between several specialties such as: obstetrics, neonatology, pediatric surgery, family medicine and requires many resources. In general, the chance of survival of newborns with gastroschisis is high. However, complex cases with complications are more likely to have an unfavorable prognosis. The therapeutic plan should start from the intra-embryonic period, from the time of the ultrasound diagnosis and it should extend over a long period of time, which can vary depending on the case, and on the surgical options. When it comes to the management of the cases, there is no valid protocol for all the cases, and there is a great variability starting with the choice of birth time, birth pathway, the option of reintegrating the intestinal loops and closing the abdominal defect. Because of this, the cases of gastroschisis represent a challenge for modern medicine, when also taking into account the fact that the etiopathogenesis of this malformation is not clearly established and that there is a large variety of therapeutic options.

Introduction. In the case of patients with reduced vestibular-palatal or vestibular-lingual ridges with a dimension under 3-4 mm, in order to allow the insertion of endoosseous implants, we are forced, more than often, to resort to osseous grafts. The bone splitting method allows, with the help of piezosurgery tools, to increase the intracortical distance and to regenerate the bony structure in a guided way, with a success rate up to 98%. Material and method. The bone splitting method was used in the case of 65-year-old female patient, who, at the level of 22, had internal radicular resorption with mobility of III degree. The patient asked for both a provisory as well as a permanent aesthetic solution regarding the replacement of 22 after extraction. Therefore, we used the 3D scanner in order to determine the osseous dimension necessary for an implant insertion and, as a result of the clinical examination, the patient had an intracortical vestibular-palatal dimension of 3 mm. In this clinical study, the decision was to augment the ridge through the bone splitting method and to insert a 3.7 mm implant in diameter and 8 mm in length at the level of 22 area. Conclusions. During the same visit we performed the extraction, the bony augmentation of the ridge, the insertion of the implant and a provisory crown was cemented. As a result of the augmentation, the intracortical diameter increased from 3 mm to 5 mm and the patient was given a permanent prosthesis 2 month after implant insertion.

This study is a review of the specialised literature regarding the intraoral autogenous bone grafts used in oral implantology. 382 abstracts of scientific papers, 71 full-text scientific articles and 9 specialized books, out of which 113 included in the references, were studied. The area behind the mandibular third molar, the posterior buccal area of the mandible body and the mandibular symphysis are the most frequently used sites for intraoral block bone harvesting. The mandible should be the first choice in the intraoral donor site selection for peri-implant augmentation, if the quantity of bone that is going to be harvested is considered to be enough.

Aim. The purpose of this study was to examine and health attitudes/behavior of Romanian dental students (n = 110). Materials and methods. A questionnaire known as HU-DBI (Romanian version) was administered to 110 students in the last year of studies. In the same time was evaluated the prevalence of dental caries and some correspondence between the HU-DBI index and oral health status for every student. The questionnaire was administered after their written informed consent. Dental caries status was evaluated using the world health Organization (WHO) caries diagnostic criteria for decayed, missing and filled teeth and surfaces (DMF-T and DMF-S, respectively). Data were statistically analyzed. Results. The prevalence of dental caries was 60% only 6.7% (8 students) had DMF-T = 0. The mean DMF-T recorded was 7.3 (± 0.35). When relating the different DMF values to the HU-DBI responses, a statistically significant relation was found between seven items and DMF scores of their components and indices. The HU-DBI score ranged from 6 to 12 (mean 9.8). Low DS and DT values significantly correlated with a high total HU-DBI score (p < 0.05); that is subjects with low levels of dental disease had more positive oral health attitudes and behavior. Conclusions. The positive attitude of dental students towards the care of their own teeth and gums is important in determining the oral health conditions of their patients. In passing through the curricles the dental students should be able to set a personal example in oral health.

Objective. The study analyses the peri-implant bone strain resulted during implant anchorage for molar intrusion. Material and method. A model and a mini-implant in finite element were created using tridimensional scanning and volumetric computer tomograf, and used to simulate molar intrusion using mini-implant anchorage. The force of 224 g was applied on the first molar and 122 g on each mini-implant. ANSYSv11 program was used to measure the stress-strain relation in the bone model using finite element analysis. Results and discussion. The peri-implant bone maximum stress value of 9.8 MPa correspond to 890 microstrain and molar peri-radicular stress value of 2.5 MPa correspond to 36 microstrain. Conclusions. Finite element analysis is a complex mathematical calculation allowing to receive and process data in the model, data that can be transferred in clinical practice. The data resulted in this study, correlated with the estimated effects of bone remodeling effects when subjected to mechanical factors, shows that the mini-implant mechanical induced values of peri-implant and periradicular bone strain are located in-between disuse interval and adapted interval. In order to increase the relevance of the results, an improved computer tomographic investigation and calibrated model related to the patient characteristics, are needed.

An in-depth knowledge of the characteristics of the appliances with which we work is very important because it helps us to better understand the indications, contraindications, strengths and their possible shortcomings. The structural design elements play an important role in this context. One of the most commonly used methods for investigating them is represented by scanning electron microscopy. Using a scanning electron microscope we studied the aspects of the surface microstructure of metal and ceramic brackets. The results show that each of them has design features that help with the delivery of orthodontic forces. These characteristics differ drastically in shape from one type of bracket to the other, a square or diamond-shaped network in the case of metal brackets and an appearance of granules dispersed on the surface of the ceramic brackets.

Dental biomaterials are designed to restore form and function of the dental tissue, to protect the remaining tissue and to create a bond between the dental surface and the restorative material. Due to their proximity to dental structures and oral mucosa, dental biomaterials must fulfil the requirements of biocompatibility and biological durability. The research in the field is focused on achieving these requirements by developing new highly performant biomaterials. But at present, composite materials still present some drawbacks like the polymerisation shrinkage associated to the curing process that leads to the adhesive interface breakdown and marginal microleakage. Composite materials may release substances into the oral environment during setting and later as a result of material degradation. Different side effects of composite materials and their components have been reported i.e. cytotoxic, teratogenic, carcinogenic, mutagenic or genotoxic. Despite the developments in the field, at present no „ideal“ restorative biomaterial with similar characteristics with the natural teeth and completely biocompatible is available. However, the application of strict clinical protocols may improve the above mentioned shortcomings.

The coherent low-frequency radio emission detected by LOFAR from Gliese 1151, a quiescent M4.5 dwarf star, has radio emission properties consistent with theoretical expectations of star–planet interactions for an Earth-sized planet on a 1- to 5-day orbit. New near-infrared radial velocities from the Habitable-zone Planet Finder (HPF) spectrometer on the 10 m Hobby–Eberly Telescope at McDonald Observatory, combined with previous velocities from HARPS-N, reveal a periodic Doppler signature consistent with an

exoplanet on a 2.02-day orbit. Precise photometry from the Transiting Exoplanet Survey Satellite (TESS) shows no flares or activity signature, consistent with a quiescent M dwarf. While no planetary transit is detected in the TESS data, a weak photometric modulation is detectable in the photometry at a ∼2-day period. This independent detection of a candidate planet signal with the Doppler radial velocity technique adds further weight to the claim of the first detection of star–exoplanet interactions at radio wavelengths and helps validate this emerging technique for the detection of exoplanets.

Published: September 2021

We present an improved methodology to obtain absolute position and velocity of meteor head echoes, which can yield orbital information, generally limited to the use of High-Power, Large-Aperture radars, using an advanced-designed specular meteor radar. The observations, which were performed during a period when an outburst of the β-Taurid meteor shower was expected, were performed with the Southern Argentine Agile MEteor Radar. Three different methodologies are utilized to confirm our results: an improved interferometric solver building on previous work, and two different target localization techniques using remote receiving stations. In addition, we performed simultaneous optical observations during the meteor shower period. Overall, 71 radar head echo events were detected and analyzed using interferometry, while 12 of those events have detected signals strong enough to be analyzed using localization methods at the remote sites. Due to poor weather, however, the optical cameras only observed two events simultaneously with the radar. Results from these events are in agreement with the radar results. We find that interferometry methods from both radar and optical data resulted in the most accurate estimation of meteor properties, while target localization techniques derived similar results, albeit with larger uncertainty. We also computed heliocentric meteoroid orbits, and while a fraction was hyperbolic, we believe these to be due to uncertainty. Two events are suspected to be β-Taurid shower members.
The Verification of Ecological Citizen Science Data: Current approaches and future possibilities

Published: September 2021

Citizen science schemes (projects) enable ecological data collection over very large spatial and temporal scales, producing datasets of high value for both pure and applied research. However, the accuracy of citizen science data is often questioned, owing to issues surrounding data quality and verification, the process by which records are checked after submission for correctness. Verification is a critical process for ensuring data quality and for increasing trust in such datasets, but verification approaches vary considerably among schemes. Here, we systematically review approaches to verification across ecological citizen science schemes, which feature in published research, aiming to identify the options available for verification, and to examine factors that influence the approaches used (Baker et al. 2021). We reviewed 259 schemes and were able to locate verification information for 142 of those. Expert verification was most widely used, especially among longer-running schemes. Community consensus was the second most common verification approach, used by schemes such as Snapshot Serengeti (Swanson et al. 2016) and MammalWeb (Hsing et al. 2018). It was more common among schemes with a larger number of participants and where photos or video had to be submitted with each record. Automated verification was not widely used among the schemes reviewed. Schemes that used automation, such as eBird (Kelling et al. 2011) and Project FeederWatch (Bonter and Cooper 2012) did so in conjunction with other methods such as expert verification. Expert verification has been the default approach for schemes in the past, but as the volume of data collected through citizen science schemes grows and the potential of automated approaches develops, many schemes might be able to implement approaches that verify data more efficiently. We present an idealised system for data verification, identifying schemes where this hierachical system could be applied and the requirements for implementation. We propose a hierarchical approach in which the bulk of records are verified by automation or community consensus, and any flagged records can then undergo additional levels of verification by experts.
The ABC of linear regression analysis: What every author and editor should know
Authors: Bazdaric Ksenija , Sverko Dina , Salaric Ivan , Martinovic Anna , Lucijanic Marko
Published: September 2021

Regression analysis is a widely used statistical technique to build a model from a set of data on two or more variables. Linear regression is based on linear correlation, and assumes that change in one variable is accompanied by a proportional change in another variable. Simple linear regression, or bivariate regression, is used for predicting the value of one variable from another variable (predictor); however, multiple linear regression, which enables us to analyse more than one predictor or variable, is more commonly used. This paper explains both simple and multiple linear regressions illustrated with an example of analysis and also discusses some common errors in presenting the results of regression, including inappropriate titles, causal language, inappropriate conclusions, and misinterpretation.

Published: September 2021

Teaching strategies play a vital role in improving learners’ performance. This study investigated the effect of Guided Discovery Instructional Strategy (GDIS) on Grade nine learners’ performance in chemical reactions and determined the effect of GDIS on gender. A quasi-experimental design was used with a sample comprised 75 Grade nine learners purposively selected from two schools in Mankweng Circuit based on Grade 12 poor performances. Learners were randomly assigned to the Experimental Group (EG) (N = 40) and Control Group (CG) (N = 35) taught for two weeks using GDIS for EG, and Talk and Chalk Method (TCM) for CG. The results show that there were statistically significant differences between CG post-test (T-test: t(78) = 19.89; p = 0.05); Cohen d = 4.40 for EG and CG T-test: t(68) = -1.03; p > 0.05; Cohen d = 0.2. EG taught using GDIS outperformed those using TCM (ANCOVA: F = 361.49, p = 0.05). GDIS did not discriminate against gender in EG because no statistically significant differences in performance after the intervention (Mann Whitney U-test: U = 178.50, p = 0.58), suggesting that GDIS improved all learners’ performance in chemistry, but not CTM. The findings provide teachers and stakeholders with empirical evidences on a strategy that improved learners’ performance. Also, GDIS did not discriminate against gender like the TCM, suggesting that the strategy encourages girls to study science, which contributes to narrowing the existing gender gap of male and female in Science, Technology, Engineering and Mathematics (STEM) subjects.

By the end of the 20th century, the most common and traditional paper and pencil tests (PBT) were faced with an increasing set of difficulties and drawbacks. Proceed and meet the measurement and evaluation needs of the 21st century; it is mandatory to have radical and qualitative changes. The accelerating pace of technological innovation in Education shows a clear path to computer-based testing, which offers a more engaging and innovative testing environment, as well as the ability to obtain instant results and feedback, the use of dynamic, multimedia learning objects (LO), and the implementation of adaptive, individualized assessment approaches. In this sense, this paper presents an adaptive formative assessment framework in which test adaptation is based on multiple criteria. The presented system bases its adaptation on the test takers' proficiency, schemata, desirable learning goal, cognitive level, and learning style. The main objective of this paper is to discuss the value of the adaptive testing system. Therefore, it presents the design and implementation of the system and the adaptive rules employed.
A First Experience of Using Failure Report as a Reflective Tool in Engineering Education
Authors: Harithuddin Ahmad Salahuddin Mohd
Published: September 2021

The paper reports the first use of failure report as a reflective learning tool in engineering education from a university in Malaysia. Failure Report is a document that publishes and discusses failures as part of a reflective learning process for students. This reflective learning method attempts to encourage students to actually learn from failure and to take negative experiences as a learning opportunity. This paper describes the experience of introducing Failure Report as a means for engineering students to reflect their learning after completing an engineering de-sign project. The Gibbs’ Reflective Learning Model is used as the base of the reflective work. This introductory study reveals some findings on how students view and reflect on their failures and setbacks during the project work. It is noted that this was their first ever experience in doing a reflection study. Most of the students’ writing revolves around interpersonal skills like teamwork and communication. The element of ‘blame game’ is prevalent in their reports. In addition, based on this first experience, we provide several principles to follow to replicate the Failure Report activity and further recommendations for future failure reflection work.

Published: September 2021

Educational researchers developed an online repository of effective practices contributing to or enhancing the teaching culture at multiple higher education institutions as part of a larger project exploring institutional teaching culture. The repository was designed to be a companion document to the Institutional Teaching Culture Perception Surveys (ITCPS), a resource for administrators, educational developers, and Centers for Teaching and Learning (CTL) striving to cultivate institutional cultures that support the development of teaching and learning. This paper outlines the methods for developing this repository, summarizes findings, identifies some of the practices included and highlights areas for future development.
La pédagogie comme lieu d’interactions entre savoirs, recherches et pratiques
Authors: Vellas Etiennette
Published: September 2021

Ce texte est une entrée dans l’espace intermédiaire que représente la pédagogie conçue comme élaboration d’une « théorie pratique ». Il rappelle que le pédagogue réalise, à partir de sa propre expérience éducative, une recherche spécifique de cohérence entre finalités, savoirs et pratiques de l’éducation. Après une contextualisation de la recherche pédagogique dans l'avènement des sciences de l'éducation, puis la définition de la pédagogie d’une personne et de celle d’un groupe, le texte se focalise sur le type de travail opéré par les pédagogues avec et sur leurs savoirs de référence. Trois processus sont mis en évidence dans ce travail pédagogique dont le but est d’agir et faire agir (au) mieux sur le terrain de l’éducation : une utilisation prévisible des savoirs de référence ; un travail plus aléatoire et créateur d’autres savoirs (les concepts de créolisation et de sérendipité sont appelés pour l’expliquer) ; un travail de sélection, laissant des savoirs issus de la recherche sur la touche des terrains éducatifs. Théoriciens de leurs propres actions éducatives, le pédagogue et le groupe de pédagogues apparaissent comme des créateurs de savoirs singuliers qu’ils transmettent, en entraînant dans cette diffusion des savoirs des sciences humaines.
Fear vs. Threat, School Shootings and Violence
Authors: Benigno Stephen
Published: September 2021

The first recorded school shooting took place in Charlottesville, Virginia on November 12, 1840. The most recent school shooting took place on July 11, 2019 in Hartford, Connecticut. Over 500 school shootings have taken place since the Charlottesville incident. Sadly, school shootings are not an anomaly to many communities in America. Administrators, and particularly principals, are faced with significant challenges in creating an environment that is conducive to the development of a productive and safe school culture. The content of this manuscript will explore the existing administrative roles and responsibilities with respect to school safety and the implementation and supervision of those procedures. Also discussed in the manuscript will be the role that fear plays in the decision making process and how some decisions may be misplaced and could be redirected toward more favorable areas of emphasis (i.e., counseling, active supervision, alternative academic options, community outreach, and inclusive student opportunities).
School Resource (Police) Officers in Schools
Authors: Mallett Christopher A.
Published: September 2021

Having police officers in schools (school resource officers – SROs) is controversial with a growing debate as their presence has proliferated nationally over the past 20 years. A majority of high schools and middle schools today have police on campus providing a variety of services, though primarily law enforcement. While the intent is to provide improved school safety and protection to students, unexpectedly this has not been the outcome for many school campuses when reviewing most criminal activity and school shootings. While the presence of SROs is complicated, the unintended impact has harmed more students than anticipated by criminalizing misbehaviors and disorderly conduct, making the learning environment less conducive by negatively changing school climates and disproportionately impacting many already at-risk young people.

Published: September 2021

This chapter aims to explain the bioprospecting situation in Bangladesh from an analytical, philosophical, and indigenous standpoint. It has three parts: looking at the philosophical history of bioprospecting; looking at combining the concept of bioprospecting linked with forest and the indigenous people, which also shows the combination of the bioprospecting concept with the indigenous people in Bangladesh; and asking some question based on the critical analysis. Methodologically, this study aligns with the indigenous standpoint theory and critical discourse analysis, where mostly the authors adopted secondary data. The proposal—in effect—is like this: what needs to be done in the question appropriation and translation of indigenous knowledge particularly of the Rakhain people. Although the focus is Bangladesh, the authors believe that this situation exists in many countries. Therefore, this research may raise similar askings and can contribute to global efforts in this regard.

Published: September 2021

This chapter introduces social entrepreneurship plans aimed at establishing an entrepreneurial ecosystem in academia. The program makes use of the university's literacy technology and academic assistance. This program is designed for lecturers and higher education students to help MSMEs. Ecological entrepreneurship can be formed through design activities. Through appropriate teaching design and activity duration, activity mechanism, and recognition of students' academic performance and course conversion, the plan has achieved high success on the basis of implementation, and the results can be seen from the output of the output form. The plan also implemented a quality assurance system aimed at achieving student standard achievement (SSA). In addition, supporting organizations outside academia also ensure that the social entrepreneurship technology literacy program for small, medium, and micro enterprises can truly establish an entrepreneurial ecosystem in academia.
