THE USE OF THE MOZAIK INTERACTIVE PLATFORM AS A SOCIAL OBJECT FOR EDUCATIONAL INTERACTION BETWEEN THE PARTICIPANTS OF THE LEARNING PROCESS
Authors: Derkach Larysa , Konstankevych Larysa
Published: March 2021

The article characterizes the Mozaik interactive platform and its main components – mozaBook and mozaWeb,
which are used by lecturers-philologists to give classes on the Ukrainian language to undergraduate students whose
specialization is "Secondary Education" (educational program "Ukrainian Language and Literature. World Literature").
The possibilities of use of the software at different stages of educational process have been described. The didactic
functions of the use of the mentioned resources in the process of teaching the disciplines “Practicum on the Ukrainian
language” and “Methodology of teaching the Ukrainian language” have been outlined. The mozaBook software has
been analyzed as a social object which provides pedagogical interaction of scientific methodology of rational-logical
thinking with emotional and imaginative presentation and perception of information. The possibilities of mozaBook and
mozaWeb have been used to improve the perception and acquisition of scientific information and to increase the level
of educational achievements. The authors have analyzed the expediency of using e-textbooks, media library, software
for attaching information of various types and use of mozaBook tools (“Spelling and grammar”, “Parts of speech”,
“Dictionary cards”, “Language games”, “Questionnaire”, “Decoding”, “Tests”) while explaining and illustrating theoretical material, summarizing and systematizing material that has already been learned. It has been shown that the Mozaik
interactive platform and its components make the classes more informative, compact, emotionally attractive,
mobile and multifunctional.
La necesaria formación del profesorado universitario ante la docencia virtual
Authors: Rando Burgos Esther
Published: March 2021

Los últimos meses, con la fatídica llegada de la Covid-19, han supuesto un auténtico tsunami en nuestras vidas, en todas las esferas, también en la docente. En apenas días se pasó de la ya tradicional docencia presencial a la docencia virtual. Estudiantes y docentes nos vimos de lleno en un nuevo escenario que hasta entonces se limitaba a cuestiones concretas y que transformó nuestro día a día. Y, podría afirmarse, que se ha superado con éxito o, al menos, de la mejor forma posible dado los limitados recursos, la situación de incertidumbre generalizada, gracias a una reinvención casi diaria. Transcurridos estos primeros tiempos y aún sin saber qué escenario tendremos en el próximo curso una cuestión parece evidente: la docencia virtual ha llegado para quedarse. Consecuencia de ello es la necesaria adaptación del docente al nuevo escenario, lo que pasa por la formación en docencia virtual para, valga la redundancia, poder formar a nuestros estudiantes. El objetivo del presente trabajo se centra en analizar la importancia y necesaria formación del docente en el entorno universitario ante la docencia virtual.
Representations of Surveillance and Perceptual Technologies at Military Museums
Authors: Walby Kevin , Pauls Haley
Published: March 2021

Drawing from fieldwork at military museums across Manitoba, Canada, we explore the objects and narratives used to curate museum displays featuring what Bousquet (2018) calls “military perception.” Using Bousquet’s categories of military perception to organize our analysis, we examine how these museums position scopes, sonars, camouflage, and other devices meant to create visibility or invisibility as aesthetic objects rather than as instruments enabling state violence. With a focus on curatorial strategies and the arrangement of objects at these museums, we explore how surveillance and camouflage displays are organized to minimize the harm that military interventions cause and align the affect of the viewer with the form of Canadian nationalism animating the museum and against “enemy” others and spaces, a process we refer to as encasement. In conclusion, we reflect on what our analysis adds to literature on military museums and representations of surveillance.

Assessment of the 31-Gene Expression Profile Test by Dermatologists: A Cross-Sectional Survey from National Dermatology Conferences
Authors: Marson Justin , Litchman Graham , Svoboda Ryan , Glazer Alex , Farberg Aaron , Winkelmann Richard , Rigel Darrell
Published: March 2021

Background: The 31-gene expression profile (31-GEP) test uses 31 genetic markers obtained from the initial biopsy of a melanoma to assess melanoma-specific survival and sentinel lymph node positivity. 
Objective: To assess the professional understanding, opinions, and clinical usage of the 31-GEP test by dermatologists.
Methods: Data from 589 unique dermatologists were collected during 2 virtual, nation-wide dermatology conferences via  an 18-question survey on practice demographics and their clinical use and opinion of the 31-GEP test.
Results: Participants reported that integrating the 31-GEP test may benefit patients by increasing knowledge and understanding (72.5%), personalizing treatment options (58.8%), and easing uncertainty about the future (59.7%). Benefits of using the 31-GEP test included identifying true negative patients in high-risk populations (65.6%) as well as true positives in low-risk populations (70.6%).A majority of participants also noted that if a patient received a 31-GEP Class 2B result, they would escalate subsequent management even if the lesions were classified as T1 (61.4%) or AJCC8 Stage I (59.0%). 84.9% of participants were somewhat to very likely to use 31-GEP testing for patient management or recommend this test to a colleague.
Limitations: Potential respondent-selection and recall bias.
Conclusion: Dermatologists are increasingly integrating the 31-GEP test into their melanoma clinical management decisions. As the 31-GEP test becomes more prevalent in practice, patients may benefit from decreased anxiety and uncertainty from enhanced prognosis, decreased need for unwarranted procedures such as sentinel lymph node biopsy and optimized allocation of healthcare resources.
Global Burden of Skin and Subcutaneous Disease: A Longitudinal Analysis from the Global Burden of Disease Study From 1990-2017
Authors: Giesey Rachel Lynn , Mehrmal Sino , Uppal Prabhdeep , Delost Gregory
Published: March 2021

Background: The global prevalence and disability of skin and subcutaneous diseases have grown annually in recent decades. Large-scale epidemiologic data is useful for better characterization of skin disease to create more impactful and sustainable interventions.

Methods: We assessed multiple global trends in skin and subcutaneous disease from 1990 to 2017 in 195 countries worldwide through the latest Global Burden of Disease Study results from 2017.

Results:Skin and subcutaneous disease grew 46.8% between 1990 to 2017 and is ranked fourth by incidence of all causes of disease. There is global variation in disease burden when stratified by age, sex, geographic regions, and sociodemographic index. Many global regions experience disproportionately elevated disease burden from certain subcategories of skin and subcutaneous disease. Wealthier countries generally experienced the highest age-standardized disability rates of skin and subcutaneous disease.

Conclusion: The incidence, prevalence, and disability of skin and subcutaneous diseases are increasing disproportionately among countries and sociodemographic groups. This data may improve our understanding of skin and subcutaneous diseases to direct funding and resources to reduce global disparities.
Extraspecial two-Groups, generalized Yang-Baxter equations and braiding quantum gates
Authors: Rowell E.C. , Zhang Y. , Wu Y.-S. , Ge M.-L.
Published: March 2021

In this paper we describe connections among extraspecial 2-groups, unitary representations of the braid group and multi-qubit braiding quantum gates. We first construct new representations of extraspecial 2-groups. Extending the latter by the symmetric group, we construct new unitary braid representations, which are solutions to generalized Yang-Baxter equations and use them to realize new braiding quantum gates. These gates generate the GHZ (Greenberger-Horne-Zeilinger) states, for an arbitrary (particularly an \emph{odd}) number of qubits, from the product basis. We also discuss the Yang-Baxterization of the new braid group representations, which describes unitary evolution of the GHZ states. Our study suggests that through their connection with braiding gates, extraspecial 2-groups and the GHZ states may play an important role in quantum error correction and topological quantum computing.
Fast equivalence -- checking for quantum circuits
Authors: Yamashita Shigeru , Markov Igor L.
Published: March 2021

We perform formal verification of quantum circuits by integrating several techniques specialized to particular classes of circuits. Our verification methodology is based on the new notion of a reversible miter that allows one to leverage existing techniques for simplification of quantum circuits. For reversible circuits which arise as runtime bottlenecks of key quantum algorithms, we develop several verification techniques and empirically compare them. We also combine existing quantum verification tools with the use of SAT-solvers. Experiments with circuits for Shor's number-factoring algorithm, containing thousands of gates, show improvements in efficiency by four orders of magnitude.

Diagnosis: A critical social reflection in the genomic era
Authors: Jutel Annemarie
Published: March 2021

© 2019, Associacao Brasileira de Pos - Graduacao em Saude Coletiva. All rights reserved. Diagnosis is a pivotal tool for the work of medicine as they categorise and classify individual ailments via a generalised schema. However diagnosis is also a profoundly social act, which reflects society, its values and how it makes sense of illness and disease. Considering diagnosis critically, as well as practically, is an important job of the sociologist. This paper reviews how a social model can provide a critical tool for viewing diagnosis in the genomic era. It explores how the formulation of diagnosis, be it via genetic explanations or microbiological ones, are the product of social discovery, negotiation, and consensus.

Authors: Akmal Yusrizal , Humairani Rindhira , Muliari Muliari , Hanum Hanum , Zulfahmi Ilham
Published: March 2021

Phytoplankton is a bio-indicator of fertility in waters. This study aims to determine the impact of detergent and pesticide waste on the phytoplankton community structure in in tilapia aquaculture media. The phytoplankton identification stage was carried out at the MIPA Laboratory Almuslim University. The parameters studied were phytoplankton abundance, diversity index, uniformity index, dominance index, and water quality parameters. The results of this study showed that detergent and pesticide waste at the end of the study had caused a decrease in the abundance value of phytoplankton by 3,250 individual/L and 3,750 individual/L. In the control treatment, the highest phytoplankton composition was dominated by Chaetoceros sp., while the pesticide and detergent treatments were dominated by Golenkenia sp. and Microcystis sp. Exposure to detergent and pesticide waste reduced the diversity index value, the phytoplankton uniformity index value. At the beginning of the study, it has a moderate diversity index (H '= 2.485–3.072), while at the end of the study it shows low diversity (H' = 2.111–2.375). Furthermore, at the beginning and at the end of the study there was a decrease in the uniformity index value (E = 0.87–1.01) and (H '= 0.88–0.94).

How Pills Undermine Skills: Moralization of Cognitive Enhancement and Causal Selection
Authors: Mihailov Emilian , López Blanca Rodríguez , Cova Florian , Hannikainen Ivar Rodríguez
Published: March 2021

Despite the promise to boost human potential and wellbeing, enhancement drugs face recurring ethical scrutiny. The present studies examined attitudes toward cognitive enhancement in order to learn more about these ethical concerns, who has them, and the circumstances in which they arise. Fairness-based concerns underlay opposition to competitive use—even though enhancement drugs were described as legal, accessible and affordable. Moral values also influenced how subsequent rewards were causally explained: Opposition to competitive use reduced the causal contribution of the enhanced winner’s skill, particularly among fairness-minded individuals. In a follow-up study, we asked: Would the normalization of cognitive enhancement alleviate concerns about its unfairness? Indeed, proliferation of competitive cognitive enhancement eradicated fairness-based concerns, and boosted the causal role of the winner’s skill. In contrast, purity-based concerns emerged in both recreational and competitive contexts, and were not assuaged by normalization.
Reduction of prejudice toward unaccompanied foreign minors through audiovisual narratives. Effects of the similarity and of the narrative voice
Authors: Guerrero-Martín Iñigo , Igartua Juan-José
Published: March 2021

This study focuses on the reduction of prejudice toward foreign unaccompanied minors (UAMs) by means of audiovisual testimonial messages. Specifically, it analyzes the role of two narrative elements that can influence, in an indirect way, the intention to share the message, the feelings toward UAMs, the intention to approach UAMs, and the intention to collaborate with an NGO that provides support to immigrants. With this goal in mind, an experimental study (N = 500) was conducted using a 2 × 2 factorial design, where the factors analyzed were similarity in terms of social identity (high vs. low) and narrative voice (first-person vs. third-person). No interaction effects of similarity and narrative voice on identification or transportation were observed. However, multiple serial mediation analyses were statistically significant. A significant indirect effect of similarity on dependent variables was observed through perceived similarity (primary mediator), identification and transportation (secondary mediators), and counterarguing and reactance (tertiary mediators). Similarly, the narrative voice also had a significant indirect effect on the dependent variables that was explained by the increase in identification and transportation, and by the reduction in counterarguing and reactance. This work improves the understanding of the mechanisms that explain the impact of narratives and demonstrates that certain narrative elements can increase the effectiveness of audiovisual testimonial messages designed for the prevention of racism and xenophobia.

Authors: Pontes da Silva Alison , Leonardo Santos Silva Diogo , Braga Dantas Bruna
Published: March 2021

OBJETIVO: Verificar os dados epidemiológicos sobre a influenza pandêmica no Brasil. METODOLOGIA: Estudo de caráter documental e retrospectivo, com dados do Departamento de Informática do Sistema Único de Saúde (DATASUS), entre 2009 e 2010. As notificações foram coletadas quanto à classificação final e os casos confirmados foram analisados por região geográfica, evolução, sexo, faixa etária, condição de gestação e taxa de letalidade. RESULTADOS: Durante as fases de contenção e mitigação, houveram 97.250 notificações, das quais 55,7% foram confirmadas e 44,3% descartadas. O ano de 2009 concentrou o maior número de notificações (N=89.642) em comparação com 2010 (N=8.664). Os dados por região indicaram que as regiões Sul e Sudeste detiveram grande parte dos casos confirmados e óbitos, embora a região Centro-Oeste tenha obtido a maior letalidade do país. Quanto ao perfil demográfico, foi possível observar que o sexo feminino deteve os maiores percentuais em todas as variáveis analisadas. Os maiores percentuais de casos confirmados, cura e óbitos ocorreram em indivíduos entre 20 e 29 anos, enquanto que a maior letalidade foi observada entre 50 a 59 anos. Também se verificou que as mulheres gestantes, apesar de representarem uma minoria dos casos notificados, detiveram uma letalidade quase duas vezes maior que as não gestantes. CONCLUSÃO: Logo, a influenza pandêmica afetou significativamente a população brasileira, especialmente em 2009, apresentando padrão de circulação elevado no Sul e Sudeste e maior letalidade no Centro-Oeste. Afetou principalmente mulheres, adultos jovens e foi mais letal entre a faixa etária de 50 e 59 anos, assim como em gestantes. Palavras chave: Epidemiologia. Vírus da Influenza A Subtipo H1N1.

Construct Validity in Software Engineering
Authors: Sjøberg Dag , Bergersen Gunnar
Published: March 2021

Empirical research aims to establish generalizable claims from data. Such claims involve concepts that often must be measured indirectly by using indicators. Construct validity is concerned with whether one can justifiably make claims at the conceptual level that are supported by results at the operational level. We report a quantitative analysis of the awareness of construct validity in the software engineering literature between 2000 and 2019 and a qualitative review of 83 articles about human-centric experiments published in five high-quality journals between 2015 and 2019. Over the two decades, the appearance in the literature of the term construct validity increased sevenfold. Some of the reviewed articles we reviewed employed various ways to ensure that the indicators span the concept in an unbiased manner. We also found articles that reuse formerly validated constructs. However, the articles disagree about how to define construct validity. Several interpret construct validity excessively by including threats to internal, external, or statistical conclusion validity. A few articles also include fundamental challenges of a study, such as cheating and misunderstandings of experiment material. The diversity of topics discussed makes us recommend a minimalist approach to construct validity. We propose seven guidelines to establish a common ground for addressing construct validity in software engineering.
Open Mesh versus Laparoscopic Mesh Repair of Inguinal Hernia : in Terms of Patient Satisfaction
Authors: Umesh Singh, Varnika Gupta2
Published: March 2021

Background- Inguinal hernia is the most common type of external abdominal hernia. Open
Lichtenstein method or laparoscopic method can be employed to repair inguinal hernia. The superiority of
laparoscopic mesh hernioplasty over open mesh hernioplasty is debatable.
Method- This prospective study was done on 120 patients in the department of surgery, LLRM medical
college, Meerut to evaluate the usefulness of laparoscopic mesh hernioplasty (TEP Technique) for
inguinal hernia repair versus conventional open mesh hernioplasty (Lichtenstein Technique) in terms of
complications, pain and recurrence. Equal number of subjects were put in two groups : open mesh repair
group and laparoscopic mesh repair group.
Results- The mean age of the patients with inguinal hernia including both groups was 50 yrs. The mean
operation time of Laparoscopic TEP mesh hernioplasty was 71.33 minutes while that of Open Lichtenstein
repair was 36.33 minutes. Postoperative analgesic requirement was significantly lower in the patients operated
by TEP technique as compared with patients treated by Open Lichtenstein’s technique. In TEP group, two
patients developed neuralgia, one patient developed fever, 1 patient developed hematoma whereas in the
open group there were 3 cases of neuralgia formation and 3 cases of fever.
Conclusion- In all, Laparoscopic mesh hernioplasty using TEP technique is a novel technique with its
share of advantages and disadvantages. There are potential benefits of laparoscopic inguinal hernia repair
for inguinal hernias in terms of post-operative pain, hospital stay and post operative complications. We
recommend that a surgeon should use this laparoscopic technique for hernia repair after knowing all the pros
and cons of the technique, his expertise for the technique and the infrastructure available.

Authors: Sudhir Sase  , Alka Gore  , Dimple Gajwani
Published: March 2021

Background: Yoga is a form of alternative medicine, which aims for an overall physical, mental, andspiritual health. Several benefits of yoga in terms of disease prevention have been well documented inliterature. However, there is a lack in the studies relating to its prevalence, especially in the Indian scenario.Here we aimed to decipher the prevalence of yoga practice in the Kolhapur population.Method: A survey was conducted on 5003 residents of Kolhapur. The survey was designed to evaluate theknowledge and practice of yoga in the respondents. Socio-demographic variables were presented by MSExcel. Logistic regression was performed by R-studio 1.2.5001.Results: Most of the yoga users were between 40-49 years. The primary occupation of most of them wasservice. Men were more likely to practice yoga, as compared to females (OR-0.29, P<0.05). Also, older(OR-1., P<0.5) and retired people (OR-1.8, P<0.05) were more like to practice yoga. Yoga was also shownto be mostly practiced among people of higher economic status as opposed to people with low economicstatus.Conclusion: This is the first study on the prevalence of yoga practice in Kolhapur population. Results depictthat a considerable number of people knew about yoga, but only a few of them practiced it. Additionalstudies are thus required for a better deduction of yoga prevalence.
Monetary value of human capital disclosure for predicting future business earnings
Authors: Magau Mpho D. , Roodt Gerhard , Van Zyl Gerhardus
Published: March 2021

Orientation: Human capital (HC) is a key dimension of intellectual capital (IC) that creates shareholder value when integrated with structural capital (SC) and relational capital (RC). The disclosure of HC reveals how the human resource (HR) practices support business growth.Research purpose: The primary focus of this study was to investigate the extent of how human capital disclosure (HCD) could predict organisational performance (expected future earnings) of the Johannesburg Stock Exchange (JSE)-listed companies.Motivation for the study: Human capital disclosure reduces information asymmetry, predicts future business performance and improves the investors’ buy-sell-hold decisions.Research approach/design and method: A causal, comparative design was applied quantitatively in a cross-sectional survey of 150 top- and low-performing JSE-listed companies sampled based on their market capitalisation. A self-constructed disclosure index with a seven-point scoring system was developed to examine the extent of disclosure across 81 items. Subsequently, multiple regression analysis was computed to test the relationship between the dependent and independent variables.Main findings: Human capital disclosure was associated with both the market capitalisation and book value. Overall, no mediation of human resource risk disclosure (HRRD) against organisational performance was found. Lastly, information disclosed on gender diversity yielded the interaction effect with both structural capital disclosure (SCD) and relational capital disclosure (RCD) but not with HCD.Practical/managerial implications: Human capital disclosure identifies key HR practices that drive organisational performance and create shareholder value. This information can potentially improve benchmarking and support investor decision-making.Contribution/value-add: The study provides a novel contribution to IC theory by demonstrating how HCD can be used to identify HR practices that leverage the monetary value of HC for business improvement.
Diagnostic accuracy of chest computed tomography in improving the false negative rate as compared to reverse transcriptase polymerase chain reaction in coronavirus disease 2019 pneumonia
Authors: Ravikanth Reddy
Published: March 2021

Background:

Early differentiation between emergency department (ED) patients with and without coronavirus disease 2019 (COVID-19) is very important. The diagnosis of COVID-19 depends on real-time reverse transcriptase polymerase chain reaction (RT-PCR). On imaging, computed tomography (CT) manifestations resemble those seen in viral pneumonias, with multifocal ground-glass opacities and consolidation in a peripheral distribution being the most common findings. Although these findings lack specificity for COVID-19 diagnosis on imaging grounds, CT could be used to provide objective assessment about the extension of the lung opacities, which could be used as an imaging surrogate for disease burden. We set out to investigate the diagnostic accuracy of chest CT scanning in detecting COVID-19 in a population with suspected COVID-19 patients.

Materials and Methods:

In this cross-sectional single-center study performed on 348 cases with clinical suspicion of COVID-19, all adult symptomatic ED patients had both a CT scan and a PCR upon arrival at. CT results were compared with PCR test (s) and diagnostic accuracy was calculated.

Results:

Between February 15, 2020, and June 30, 2020, 348 symptomatic patients were included. In total, 62.3% of patients had a positive PCR and 69.8% had a positive CT, resulting in a sensitivity of 94.2%, specificity of 76.7%, likelihood ratio (LR) of +2.94 and (LR) −0.18. The sensitivity of the CT tended to be higher in those with acute respiratory distress syndrome (100.0%, P = 0.017) and severe COVID-19 (98.5%, P = 0.027) than in patients with mild (82.5%, P = 0.047) and moderate COVID-19 (89.3%, P = 0.039). The diagnostic ability of chest CT was found to be high with 86.3% concordance between findings of CT and PCR. In 48 (13.7%) patients, discordant findings between CT and PCR were observed. In most cases, the CT scan was considered suspicious for COVID-19, while the PCR was negative (37/48, 77.0%). In the majority of these, the diagnosis at discharge was pulmonary infection (n = 26; 54.1%).

Conclusion:

The accuracy of chest CT in symptomatic COVID suspect patients is high, but when used as a single diagnostic test, CT cannot accurately diagnose or exclude COVID-19. Therefore, we recommend a combination of both CT and RT-PCR for future follow-up, management, and medical surveillance.
Peripheral ischemic limb necrosis (Acro-ischemia) associated with severe COVID-19 patients (COVID-19 limbs)
Authors: Khattab Khaled , Kempa Axel Tobias , Atas Riza , Asani Harun , Ehab Ahmed
Published: March 2021

The association between severe coronavirus disease 2019 and hypercoagulable state was observed in many reports. This may be explained by the presence of hypoxia, severe systemic inflammatory response, immobilization due to intensive care unit (ICU) admission, and diffuse intravascular coagulation. We report three patients who were admitted to our respiratory ICU with acute severe respiratory distress syndrome (ARDS) requiring mechanical ventilation due severe acute respiratory syndrome coronavirus 2 infection, who developed severe limb ischemia during the course of the disease.
COVID-19 and smoking
Authors: Heydari Gholamreza , Arfaeinia Hossein
Published: March 2021

Background:

Few studies have shown that smokers are more likely than nonsmokers to contract COVID-19, while others report that smokers are underrepresented among those requiring hospital treatment for this illness. This study was designed and implemented for investigating the severity and outcome of COVID-19 based on underlying smoking status.

Materials and Methods:

This was a case–control study that was implemented in Tehran and Ahvaz with all COVID-19 patients from February to July 2020. Patients were divided into two groups of COVID-19 positive (1044 cases) and negative (1231 controls) randomly based on entrance number.

Results:

The frequency of smokers in the case group is significantly lower than the control group (15.4% vs. 28%). However, the number of days of hospitalization and the use of more than 3 medications in the group of smokers were significantly higher. A comparison between groups of case and control based on smoking indicates that the death rate was significantly higher in smokers with COVID-19.

Conclusions:

The results of this study showed that although the number of smokers in COVID-19 patients is significantly lower, smokers run an aggresive curse and have higher mortality.
Use of endobronchial valve to treat COVID-19 adult respiratory distress syndrome-related alveolopleural fistula
Authors: Pathak Vikas , Waite John , Chalise Som Nath
Published: March 2021

Coronavirus disease-2019 (COVID-19) pneumonia is one of the severe and most dreaded forms of illness caused by severe acute respiratory syndrome coronavirus 2. It often progresses to respiratory failure and acute respiratory distress syndrome (ARDS) requiring mechanical ventilation. ARDS can lead to multiple complications while on mechanical ventilation due to positive airway pressures in a fibrotic lung, one such complication is the development of alveolopleural fistula. Alveolopleural fistula has high morbidity and mortality. We used endobronchial valve in a patient with COVID-19-related ARDS with persistent air leak (alveolopleural fistula), which allowed us to remove the chest tube and wean the patient successfully off mechanical ventilation.
Editors comments Our Common Futures of Sustainable Work - Concluding Reflections
Authors: Abrahamsson Kenneth
Published: March 2021

These concluding remarks are divided into two sections and comprise both an overview of European policies on decent and sustainable work and a bird’s eye's view of the development of Swedish working life research in a European context. The concept of sustainable work has over the years encountered difficulties of being included in the Social Sustainability family. The launching of SDG 8 on Decent Work and Economic Growth with its focus on inclusive, and sustainable economic growth, full and productive employment, and decent work for all has given sustainable work a new and stronger position as a vision for good work. The launching of the consultation of European Pillar of Social Rights in 2017 highlights the importance of future of work and welfare systems in Europe. The role of the social dialogue for sustainable and greener jobs are crucial in a future perspective.  Sustainable welfare, social protection and social equality are prerequisites for decent and sustainable work. Working life research in Sweden has over the years interacted in various manners with the European policy and research communities. The Swedish National Institute for Working Life, abolished in 2006/07 created several European encounters, early in the new millennium, and the idea of sustainable work did have Swedish roots. Horizon Europe, current research on the Nordic labour market model and various European platforms and networks opens new windows for the social dialogue on the future European workplace. This policy discussion is urgently needed in times of Covid-19, digitalisation, and the Green Deal and pave the way for new European research programmes.
Making the Invisible Visible – Techniques for Recovering Deleted SQLite Data Records
Authors: Pawlaszczyk Dirk , Hummert Christian
Published: March 2021

Forensic analysis and evidence collection for web browser activity is a recurring problem in digital investigation. It is not unusual for a suspect to cover his traces. Accordingly, the recovery of previously deleted data such as web cookies and browser history are important. Fortunately, many browsers and thousands of apps used the same database system to store their data: SQLite. Reason enough to take a closer look at this product. In this article, we follow the question of how deleted content can be made visible again in an SQLite-database. For this purpose, the technical background of the problem will be examined first. Techniques are presented with which it is possible to carve and recover deleted data records from a database on a binary level. A novel software solution called FQLite is presented that implements the proposed algorithms. The search quality, as well as the performance of the program, is tested using the standard forensic corpus. The results of a performance study are discussed, as well. The article ends with a summary and identifies further research questions.
“Conservative Bonded Restoration (An Alternative to Full Coverage Crown): A Case Report on Endocrown

Published: March 2021

Background

The restoration of endodontically treated tooth (ETT) with substantial loss of the tooth structure is challenging as it carries a higher chance of biomechanical failure than vital tooth in restorative dentistry. Post combined with complete coverage restoration is a well-established technique to save such teeth from fracture, but it does not follow the minimal invasive principles of adhesive dentistry.

Case description

This case report describes the management of endodontically treated mandibular premolar with lithium disilicate glass-ceramic endocrown (Emax).

Conclusion

Endocrown is a feasible option for the restoration of extensively damaged posterior tooth after endodontic treatment. Since posterior teeth are vulnerable to tooth loss, endocrown, which is a single partial restoration, can be regarded as replacing a single crown with intraradicular retention.

Authors: Urbanus
Published: March 2021

Tulisan ini bertujuan untuk membahas tinjauan Alkitab terhadap nilai-nilai karakter dan implementasinya.

Ada beberapa masalah sosial yang terjadi di masyarakat Indonesia yang berskala nasional, seperti: korupsi, kolusi dan nepotisme yang saat ini selalu menjadi berita utama di setiap media massa. Masalah yang terjadi ini memiliki dampak yang besar bagi kehidupan berbangsa dan bernegara.  Setelah ditelusuri lebih dalam ternyata akar masalah dari persoalan sosial tersebut adalah karakter.

 Alkitab adalah dasar dari pendidikan karakter Kristen.

Pendidikan karakter pada bangsa Yahudi, yaitu Allah memberikan didikan teosentris dan praktis, dengan keseimbangan sehat antara faktor-faktor dalam dengan luar.  Efesus 4:13,

“Sampai kita semua telah mencapai kesatuan iman dan pengetahuan yang benar tentang Anak Allah, kedewasaan penuh, dan tingkat pertumbuhan yang sesuai dengan kepenuhan Kristus.” Setiap orang hendaknya memuliakan Allah melalui karakter  yang baik. Oleh sebab itu nilai-nilai karakter yang sudah ditetapkan oleh Kemendikbud dapat diimplementasikan dalam kehidupan sehari-hari.

Published: March 2021

Introducción: El síndrome de Apert tiene una incidencia variable. Se ha estimado una prevalencia de 1:160 mil nacimientos. Es de herencia autosómica dominante y se han encontrado algunos factores relacionados, como edad paterna avanzada.

Caso: Niña, recién nacida a término, con dificultad respiratoria, hipotonía, sindactilia y retardo del neurodesarrollo. Con Tomografía de Senos paranasales se reportó una malformación del canal semicircular lateral y del vestíbulo bilateral, se confirmó la presencia de una estenosis nasal derecha con desviación septal hacia la derecha y la presencia de estenosis bilateral de coanas. Con una TAC de cráneo se reportó Plagiocefalia unilateral izquierda y la presencia de craneosinostosis.

Evolución: En hospitalización se logró el retiro del oxígeno suplementario, recibió terapia miofuncional con lo que toleró adecuadamente la alimentación oral y se programó la corrección de estenosis de coanas en forma ambulatoria la cual se realizó a los 14 meses. A los 18 meses se realizó la cirugía de corrección de craneosinostosis con un avance fronto-orbitario, durante el período post-operatorio la paciente desarrolló una neumonía que fue tratada con antibióticos. Al resolverse el cuadro, fue dada de alta.

Conclusión: el Síndrome de Apert, un desorden congénito caracterizado por craneosinostosis coronal, sindactilia simétrica en las cuatro extremidades y malformaciones craneofaciales. El diagnóstico es clínico. El tratamiento es sintomático, relacionado con las diferentes malformaciones asociadas y se debe realizar un manejo interdisciplinario.
Ecological education and sustainable development

The development of the educational system, curriculum and pedagogical practice that would be sustainable in three segments of sustainable development stand out as special challenges for professionals dealing with upbringing and education. It is about social development, economic development and environmental protection. These three "pillars" of sustainable development must, by definition, participate equally and cohesively in practice, otherwise they are doomed to failure. Education for sustainable development is very specific primarily in its purpose and essence, and accordingly it is conceptualized in a similar way as education for peace, education for democracy, civic education. According to this definition of sustainable education, this practically means that it must be based on values such as democracy, solidarity, tolerance, equality and justice. Considering that pre-school upbringing and education represent the first stage of the educational system of a society, it is rightly expected that the first steps for lifelong learning will be taken at that level. Accordingly, it is necessary to design curricula that will ensure the intellectual and social development of children.

Las lagunas costeras son sistemas dominados por la variabilidad ambiental ocasionada por ciclos estacionales o nictémeros, lo cual influye directamente en la composición de especies como la de los peces. El objetivo de este estudio fue evaluar la variación en la composición de la comunidad de peces a 2 escalas temporales y analizar la dieta de especies marinas que utilizan la laguna en alguna etapa de su ciclo de vida. El estudio se realizó en la laguna Carbonera en la costa norte de Yucatán, México. Se recolectaron peces cada 2 h con un chinchorro playero durante un ciclo de 24 h, en campañas bimestrales de diciembre de 2010 a octubre de 2011. Las variables hidrológicas registradas y la comunidad de peces se evaluaron a escala nictémera y estacional, y se observaron cambios significativos en la temperatura y la salinidad. La riqueza específica y la diversidad de peces fueron mayores durante la noche, cuando se registraron especies marinas como los armados (Orthopristis chrysoptera), las corvinas (Bairdiella chrysoura), las mojarras (Eugerres plumieri) y los roncos (Haemulon plumierii). La mayor abundancia se obtuvo durante las horas de luz debido a la presencia de cardúmenes de juveniles de sardina (Harengula clupeola) y especies residentes (Floridichthys polyommus y Fundulus persimilis). Se analizó la alimentación de 10 especies de peces marinos en estadio juvenil, y se identificaron 4 principales gremios tróficos (piscívoros, detritívoros, malacófagos y zoobentófagos). Las especies marinas en estadio juvenil de importancia comercial que utilizan la laguna Carbonera para alimentación son las lisas, las sardinas y los roncos. Por lo tanto, este sistema brinda recursos a juveniles de especies de gran importancia para la pesca artesanal, por lo que es de suma importancia elaborar estrategias de manejo para su protección y conservación.

Timely sowing is a critical factor in realizing the yield as it ensures the vegetative growth to crop up during a period of satisfactory temperatures and fits the cultivar maturity length and growing season. In the present investigation, 38 cold tolerant rice genotypes were studied under delayed sowing conditions at College Farm, Professor Jayashankar Telangana State Agricultural University, Hyderabad. The genotypes were evaluated for yield attributing traits with a view of understanding the extent of variability and diversity present among the genotypes that could be suitable for delayed sowing conditions with cold tolerance. Analysis of variance (ANOVA) indicated significant differences for all the characters with high genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) values for tillers per plant, spikelet fertility, filled grains per panicle and seed yield per plant. High heritability coupled with high genetic advance as percent of the mean was observed for plant height, spikelet fertility, filled grains per panicle with higher variability indicating the presence of fixable gene action which may suggest a reliable crop improvement through selection of these traits. As association analysis could help the breeder to design selection strategies to improve grain yield, correlation studies were carried out which revealed the trait to be having positive relation with all the traits except panicle exertion and panicle length. Path coefficient analysis showed all the traits except panicle exertion and test weight to be exhibiting a direct positive effect on yield, selection for which should be emphasized on these positively associated traits for yield enhancement. Principal component analysis and D2 analysis together determined plant height, grain yield, panicle exertion, panicle length and yield per plant having higher contributions to the total variability, which could be taken into consideration in rice breeding programmes for further improvement in production.
