Religião e mídia
Authors: Moreira de Souza Ronivaldo , Miklos Jorge
Published: April 2022

Muito se tem estudado sobre como migração da religião para o ambiente midiático transformou a relação do fiel com as práticas religiosas sacralizadas. No entanto, pouco se discute a natureza desse sagrado emergente no espaço midiático. Este ensaio propõe uma reflexão teórica com o objetivo de investigar as mutações de natureza substancial ocorridas nas práticas religiosas midiatizadas que possibilitaram a migração do sagrado das religiões tradicionais para as religiões midiáticas. Por meio de pesquisa bibliográfica recorremos a teóricos da religião e da mídia para investigar o fenômeno por esta perspectiva. Concluímos que houve um processo de sublimação que transformou o sagrado sólido e consistente das religiões não midiáticas em um sagrado gasoso que se dissemina nas capilaridades eólicas da comunicação.

In Italy, 1400 children and 800 adolescents are diagnosed with cancer
every year. About 80% of them can be cured but are at high risk of
experiencing severe side effects, many of which respond to
rehabilitation treatment. Due to the paucity of literature on this
topic, the Italian Association of Pediatric Hematology and Oncology
organized a Consensus Conference on the role of rehabilitation of motor
impairments in children/adolescents affected by leukemia, central
nervous system tumors, and bone cancer to state recommendations to
improve clinical practice. This paper includes the results on the
rehabilitation treatment.
REFINEMENT OF NEWBORN SCREENING FOR CYSTIC FIBROSIS WITH NEXT GENERATION SEQUENCING
Authors: Rock Michael , Baker Mei W. , Antos Nicholas , Farrell Philip
Published: April 2022

Background: Newborn screening (NBS) for cystic fibrosis (CF)
has been underway universally in the USA for more than a decade, as well
in most European countries, and algorithms have been evolving throughout
this period with quality improvement projects as immunoreactive
trypsinogen determinations alone have been transformed to a 2-tier
strategy with DNA analyses. Objective: To apply next generation
sequencing (NGS) as a method for expanding the DNA tier for identifying
variants in the cystic fibrosis transmembrane conductance regulator (
CFTR) gene with minimization of unintended outcomes.
Design: Sequential quality improvement project in three phases
using plan coupled to statewide follow up and analysis of screening
outcomes in comparison to other NBS programs that use CFTR
sequencing. Results: After demonstrating feasibility in the
first phase, we studied an IRT/NGS algorithm that included CFTR
Variants with Varying Clinical Consequences (VVCCs). This revealed a
high identification of CF patients with 2-variants detected through
screening, but for every CF case there were 1.4 with cystic fibrosis
metabolic syndrome/cystic fibrosis screen positive, inconclusive
diagnosis (CRMS/CFSPID). This led us to a third phase of quality
improvement in which the VVCCs were eliminated except for R117H,
resulting in 94% 2-variant detection of patients and 0.44:1 ratio of
CRMS/CFSPID to CF. Conclusion: NGS can be used with IRT as an
effective method of identifying infants at risk for CF without an
appreciable increase in detection of either carriers or CRMS/CFSPID
cases.

Authors: Yuspin Wardah , Salsabella Sakia Agia
Published: April 2022

The presence of bitcoin invites many uncertainties, such as concerning its legality and the statement that bitcoin is not an official currency in Indonesia. Objective: This research aims to analyze the bitcoins in the perspective of the Islamic Law. Method: This research uses the literature review method. The literary materials obtained are in the form of scientific papers, online media, books, etc. that concerns the analyzed object. Findings: The circulation of bitcoin in Indonesia as a medium of exchange cannot be regarded as a currency, as it does not fulfill the terms and conditions for something to be called money. The bitcoin’s function does not commensurate with the function of money in the concept of the Islamic economy, as it tends to be a traded commodity rather than a facility of transactional exchange. In the perspective of Islamic law, the speculative use of bitcoins may bring one to the risk of violating the law on gharar (uncertainty, hazard); dharar (a transaction that may bring loss to a party); and qimar (game of chance). No authority guarantees bitcoins, and this causes harm. In conclusion, bitcoins produce more harm than good. Thus, its usage is prohibited by Islamic law. Function: This research provides an explanation of the legality of bitcoins, that may aid the Indonesian society to decide whether or not they can use bitcoins according to the law and th sharia. Novelty: There has not been any researches that study the same topic as that discussed in this article.

Published: April 2022

Introduction: The primary aetiology of chronic periapical abscesses, including E. faecalis, S. mutans, S. sanguinis, and P. gingivalis, can be eliminated using intracanal medicaments such as calcium hydroxide. The purpose of this study was to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) value of calcium hydroxide paste in the vulnerable initial 7-day of treatment against E. faecalis ATCC 29212, S. mutans ATCC 25175, S. sanguinis ATCC 10556, and P. gingivalis ATCC 33277. Methods: An in-vitro laboratory experiment using a spectrophotometer as a microdilution method was conducted to determine bacteria's MIC and MBC values on calcium hydroxide paste. The sample used in this study was four bacteria using intracanal medicament of calcium hydroxide (Ca(OH)2), incubated for seven days at 37°C, and then bacterial growth was observed. The cell inhibition percentage was calculated using optical density measurements to determine the MIC value. The low MIC and MBC were defined as sensitive bacteria to calcium hydroxide. Results: Calcium hydroxide paste against E. faecalis (ATCC 29212) with MIC values at a concentration of 750 μg/ml and MBC values at a concentration of 96,000 μg ml; S. mutans (ATCC 25175) with MIC value at a concentration of 3,000 ug/ml and MBC value at a concentration of 48,000 ug/ml; S. sanguinis (ATCC 10556) with MIC value at a concentration of 3,000 ug/ml and MBC value at a concentration of 6,000 ug/ml; P. gingivalis (ATCC 33277) with MIC value at a concentration of 6,000 ug/ml and MBC value at a concentration of 48,000 ug ml. Conclusions: Calcium hydroxide can inhibit bacterial growth activity. E. faecalis (ATCC 29212) and S. sanguinis (ATCC 10556) are more sensitive to calcium hydroxide paste than other bacteria, with the lowest MIC and MBC on seven days of incubation since the maximum calcium and hydroxyl ions are released.

Published: April 2022

Introduction: Asthma or bronchial asthma is a chronic respiratory tract inflammation process involving many cells, including their elements, and can cause severe and plentiful responses from the respiratory tract. Administration of inhalation drugs is the primary medication in treating bronchial asthma. Inhalants are given appropriately with dosage and usage period based on the severity level of bronchial asthma. This research aimed to analyse the differences in the salivary flow rate, buffer, and pH, based on the length of inhalants usage in bronchial asthma patients. Methods: The research was descriptive-comparative involving 40 bronchial asthma patients (6 male and 34 female) from the Community Lung Health Center of Bandung, taken as samples using the central theorem limit sampling method. The subjects were ordered to collect their saliva in the saliva collection cups with a draining method. Then, the salivary flow rate, buffer, and pH were examined. Data distribution was tested, resulting in normally distributed data; thus, a parametric independent t-test with a significant level of 0.05 was applied. Results: Subjects in the group of inhalant usage for more than ten years had low and very low categories of salivary flow rate, buffer, and pH. There were significant differences in the salivary flow rate, buffer, and pH of the bronchial asthma patients based on their length of inhalants usage (1-5 years; >5 years–10 years; >10 years; p<0.05). Conclusions: There are differences in the salivary flow rate, buffer, and pH based on the length of inhalants usage in bronchial asthma patients. The longer the usage period, the lower the salivary flow rate, buffer, and pH.

Authors: Nasution Aini Hariyani , Dewanti Wenny
Published: April 2022

Introduction: Due to the high prevalence of periodontal diseases that increase the possibility of tooth loss, platelet-rich fibrin (PRF) as a regenerative treatment has been proposed. PRF is a potential second-generation platelet concentrate and autologous healing biomaterial which contain growth factors that accelerate wound healing mechanisms. This study aimed to evaluate the efficacy of platelet-rich fibrin application to improve gingival connective tissue collagen density in periodontitis-induced rabbits. Methods: An experimental study with a post-test only control group design approach was conducted on 20 samples calculated using the Federer formula. Periodontitis was induced in ten rabbits with silk ligatures tied around the cervical region of central incisors teeth bilaterally for 14 days. After periodontitis occurred, phase I treatment was performed and followed by curettage. PRF was placed in the lower region as a treatment group using a split-mouth design, whereas a control group without PRF was in the upper jaw region. Subjects were euthanised after the 7th and 14th days of healing. Histopathological analysis was performed, and collagen density was quantified using ImageJ software. Statistical analysis was carried out using paired-T and two-way ANOVA tests. Results: There was a significant difference (p=0.001; p<0.05) in gingival connective tissue collagen density between treatment and control groups on the 7th and 14th days of observation. There was a significant increase in gingival connective tissue collagen density in the treatment group. Conclusion: Platelet-rich fibrin could improve gingival connective tissue collagen density in periodontitis-induced rabbits.

Published: April 2022

Introduction: Tea consumption causes extrinsic stain formation on teeth and denture surfaces, affecting personal appearance. Herbal plants extract such as green tea, bay leaf, and lime peel are potentially active agents for extrinsic stain removal. This study aimed to analyse the effectiveness of green tea, bay leaf, and lime peel extracts as toothpaste active agents for extrinsic stain removal on teeth, artificial teeth, and denture base. Methods: Twenty-five post-extracted human permanent central incisors, 25 artificial teeth, and 25 heat polymerised acrylic resin denture base (20x20x10mm) were divided into three treatment groups and two control groups. Pictures of all specimens were taken before and after stain induction and after brushing. All specimens were immersed in a tea solution made from 2 grams of tea and 100ml of 100°C boiled water to induce extrinsic stain. The immersion process was repeated every 24 hours for seven days. All specimens were then brushed using an automatic toothbrushing machine for 70 seconds on each surface, 200 grams loads, and five speeds/second. Toothpaste used for brushing were three different active agent toothpaste (treatment groups), no active agent toothpaste, and commercial whitening (control groups). Colour index analysis of the specimen pictures computerised by CIELAB method. The data were analysed by one-way ANOVA (α=0.05). Results: Green tea, bay leaf, and lime peel extract toothpaste and positive control had higher L-values of extrinsic stain removal than essential toothpaste on all specimens. There was a significant difference between green tea, bay leaf, and lime peel extract toothpaste and negative control toothpaste (p<0.05), while no significant difference was found when compared to the positive control toothpaste (p>0.05). Conclusion: Green tea, bay leaf, and lime peel extract toothpaste are effective as extrinsic stain removal on teeth and acrylic resin denture base because of abrasive materials that work together with the active agents such as epigallocatechin-3-gallate (EGCG) in green tea, eugenol in bay leaf, and naringin in lime peel.

Published: April 2022

Introduction: Gutta-Percha (GP) is a standard endodontic filling material found in pure form in the Cipetir area, Indonesia. However, a study comparing physical properties (brittleness and flowability) between pure GP and commercially used GP has not been found. Therefore, this study aims to test the brittleness and flowability of Cipetir GP compared to commercial GP. Methods: This study was quasi-experimental. Forty samples were prepared for each material and test, according to ANSI/ADA specification-GP cones-no 78 in 2006. The first step began by making a sample of Cipetir GP using moulds from a cuvette, commercial GP (Inline #80), and gypsum stone. The second step was to test the brittleness (Crease Recovery Tester) and flowability (according to ADA No. 78 of 2000) of Cipetir GP and commercial GP. Results: The brittleness test of Cipetir GP showed unbroken samples, and the commercial GP showed four broken samples. The Fisher's Exact test showed a p-value of 0.087, which means there was no significant difference in brittleness between Cipetir GP and commercial GP. At the same time, the average value of flowability of Cipetir GP and commercial GP were 6.46 mm and 0.19 mm, respectively. The unpaired t-test showed a p-value<0.05, which means there was a significant difference in the flowability between Cipetir GP and commercial GP. Conclusions: There is a brittleness similarity between Cipetir GP and commercial GP, while the flowability value of Cipetir GP is higher than commercial GP. Those initial findings showed that the Cipetir GP might become an excellent candidate to be an alternative endodontic filling.
Protecting Forested Areas in Non-Forest Zone through The Ecological Fiscal Transfer Scheme in Indonesia: A case study from Kutai Timur district
Authors: Nasir Mohamad
Published: April 2022

Ecological fiscal transfer (EFT) is an incentive scheme of budgetary transfers from different levels of a government (central and regional) to reward performances in environmental management. In Indonesia, EFT is mainly intended to protect forest zones or protected areas but does not include forested areas in the non-forest zone. This article investigates the opportunities and challenges of adopting the EFT scheme as a policy instrument to maintain the forested areas in Kutai Timur, a district in East Kalimantan province with the largest forested areas in its non-forest zone. This study applies a socio-legal approach along with a regulatory simplification instrument to examine the laws and regulations surrounding the adoption of an EFT scheme in Kutai Timur district.  It demonstrates that the Kutai Timur district government can adopt the EFT scheme, given that they have the authority to manage the APL and village funds allocation. The scheme has no specific requirements or standards, identifying priority issues in the environmental sector. To adopt the scheme, the district government should develop criteria and indicators by considering the goals and priorities of district development, the data availability, and the opportunity for every village to implement it. The preparation of these criteria and indicators must be carried out in a participatory and accountable process to be well accepted by the stakeholders. Further, the district government requires integrating the EFT scheme in district policies on village funds allocation. By implementing the EFT scheme, the district government can encourage village governments and villagers to protect and manage forested areas in their village.

Published: April 2022

Introduction

Pain assessment in children is crucial in managing postoperative analgesia; it is therefore necessary to determine the most accurate tool for assessing pain in children. The aim of this study was to evaluate the correlation between skin conductance measurements and self-reporting pain scales in children after otolaryngology procedures.

Materials and methods

Thirty-three children (N=33) were assessed for eligibility for the research. Postoperative pain was assessed using the Visual Analogue Scale; the Wong-Baker Faces Pain Rating Scale; the Face, Legs, Activity, Cry, and Consolability scale; and a skin conductance algesimeter. The postoperative pain was measured 1 and 2 hours after the surgery.

Results

There was no statistically significant correlation between self-reported pain scores and the skin conductance fluctuations in the children studied, regardless of gender or age. A statistically significant correlation was found between the existing subjective pain scales in children.

Conclusions

The skin conductance measurements do not provide an additional reliable tool for assessing pain in patients after otolaryngological procedures. The existing self-reported pain scales are sufficient to assess postoperative pain in children.

Authors: Zeqiri Jusuf , Kareva Veronika , Alija Sadri
Published: April 2022

Background: Blended learning is a new approach to teaching and learning created by combining traditional classroom learning with an online learning platform. In recent years, blended learning has become an increasingly popular form of e-learning. It is particularly suitable for transitioning from completely traditional forms of learning to online learning.

Objectives: This paper aims to examine the effect of blended learning on students’ performance and satisfaction and showcase whether students’ satisfaction with blended learning leads to performance improvement.

Methods/Approach: A quantitative research design has been utilized for data collection, consisting of a questionnaire administered to a sample of three hundred and nineteen (319) students from bachelor and master study programs at South East European University (SEEU) in N. Macedonia. Data gathered through this questionnaire have been analyzed through structural equation modelling (SEM).

Results: The results show that blended learning influences students’ performance and satisfaction.

Conclusions: Course management and interaction positively impact students’ satisfaction and performance. The interaction has a more significant effect on both satisfaction and performance outcomes from blended learning. The main conclusion is that blended learning contributes to students’ satisfaction which eventually leads to students’ improved performance.
The Partnership Network Structure of Automakers under Radical Technological Change
Authors: Isada Fumihiko
Published: April 2022

Background: Traditionally, dense network structures have dominated partnerships in the automotive industry. On the other hand, previous research in other industries has shown that network structures suitable for radical innovation include weak ties, structural holes and betweenness centrality.

Objective: The purpose of this research is to empirically analyse the effect of the ongoing and radical change in the business environment within the automotive industry, referred to as CASE (connected, autonomous/automated, shared, and electric), on the network structure of the partnerships of automobile manufacturers.

Methods/Approach: The methodology of this study is based on the use of real data on partnerships of car manufacturers around the world, analysed using social network analysis methods.

Results/Findings: The analysis confirms that there is a significant correlation between the degree of the CASE approach, the number of weak ties and the size of structural holes. In addition, several cases showed significant differences in the network structure between new technology ventures and existing legacy technology firms. The findings highlight the insight that the network structure of the automotive industry is likely to change significantly in the future due to technological innovation.
The Appropriate Work Environment for Older Employees: The Case of Slovenia
Authors: Rožman Maja , Čančer Vesna
Published: April 2022

Background: The increase in population life expectancy in developed economies is also reflected in the aging of the workforce; therefore, enterprises should create an appropriate work environment for all employees, emphasizing the older ones.

Objectives: The major objectives of this paper are to establish the impact of appropriate working conditions and training programs for older employees on their work motivation, as well as to establish the latter’s impact on the older employees’ work engagement in Slovenian medium-sized and large enterprises.

Methods/Approach: Structural equation modeling explored the links between four constructs – appropriate working conditions, training programs, work motivation, and work engagement.

Results: In Slovenian enterprises, appropriate working conditions and training programs for older employees positively impact their work motivation. Moreover, the work motivation of older employees positively impacts their work engagement.

Conclusions: These findings can be useful for employers or managers for developing targeted employee motivation and employee engagement programs to leverage the talents and dedication of older employees.
Entrepreneurial Orientation, Strategic Networking, and Croatian SMEs Performance: A Configurational Approach
Authors: Milovanović Bojan Morić , Bubaš Zoran , Mikić Mihaela
Published: April 2022

Background: Many studies on entrepreneurship indicate an affirmative entrepreneurial orientation (EO) and small firm performance interrelationship. However, the empirical results are inconclusive, especially when firms face certain contingencies.

Objectives: Strategic networking and environmental dynamism are important to SMEs’ performance; therefore, the goal of this study is to apply a configurational approach for developing a model that promotes the roles of strategic networking and environmental dynamism as moderating variables in the EO-performance relationship.

Methods/Approach: For determining which model fits the data best, a moderated linear regression analysis was used as an analytical method to test the proposed hypotheses. Specifically, configurational, contingency and universal models were examined.

Results: Results reveal that a configurational model provides a statistically better explanation of variance in performance compared to both contingency and universal models.

Conclusions: By adding strategic networking to the EO-performance relationship, our study helps explain why some firms, although restrained with internal resources, can still achieve entrepreneurial projects since required resources can be acquired from external network partners. Limitations of this study encompass the sample size, the use of a subjective scale, questioning of only one representative of the firm, and the short-term aspect of the study.

Authors: Bevanda Lea-Marija , Zaimović Azra , Arnaut-Berilo Almira
Published: April 2022

Background: Due to strong empirical evidence from different markets, existence of value premium became a financial theory standpoint. Although previous studies found that value stocks beat growth stocks in bearish and bullish markets, during the GFC, value stocks underperformed growth stocks.

Objectives: This paper aims to examine the performance of value and growth stock portfolios after the GFC. Subjects of our analysis are constituent companies of the DJIA index, out of which portfolios of large-cap value and growth stocks have been constructed and evaluated.

Methods/Approach: We measure the performance of stock portfolios, which are created based on the naïve diversification rule and random weighting approach. Statistical testing includes Levene’s homogeneity test, the Mann-Whitney U test, T-test, and the One-Sample T-test.

Results: Growth stock portfolios outperform value stock portfolios after the GFC. The dominance of growth stock portfolios compared to value stock portfolios is significant, and the value premium disappears.

Conclusions: Financial theory and investment management implications show that growth stocks have overtaken the dominance over value stocks since 2009. Causes might be in (1) expansionary monetary policy characterized by very low long-term interest rates and (2) high performance of the tech industry to which most growth stocks belong.
Early Student-at-Risk Detection by Current Learning Performance and Learning Behavior Indicators

Published: April 2022

The article is focused on the problem of early prediction of students’ learning failures with the purpose of their possible prevention by timely introducing supportive measures. We propose an approach to designing a predictive model for an academic course or module taught in a blended learning format. We introduce certain requirements to predictive models concerning their applicability to the educational process such as interpretability, actionability, and adaptability to a course design. We test three types of classifiers meeting these requirements and choose the one that provides best performance starting from the early stages of the semester, and therefore provides various opportunities to timely support at-risk students. Our empirical studies confirm that the proposed approach is promising for the development of an early warning system in a higher education institution. Such systems can positively influence student retention rates and enhance learning and teaching experience for a long term.
