TDT DVB-T2 signal coverage in rural zones
Authors: Acosta-Peña Diana , Gaona-García Elvis Eduardo , Oviedo-Perdomo Juan Pablo
Published: September 2021

This paper analyzes the Digital Terrestrial Television (DTT) signal coverage in the department of Cundinamarca, comparing two propagation models: Okumura-Hata, and Stanford University Interim (SUI). These models were selected because they allow the calculation of propagation losses in the UHF band and do not require greater precision in the cartographic information to estimate diffraction losses. As a result, was obtained that the selected models are close to the field measurements, in a range of 8 to 12 dB. In addition, adjustments were made to the propagation models obtaining the losses estimation in the signal propagation. The models were evaluated applying statistical criteria such as: correlation coefficient, mean square error and standard deviation. Finally, it was determined that the two models fit easily to the values obtained in the field measurements; however, the difference presented by the Okumura-Hata model was smaller in comparison with the SUI model; but the latest one allowed a better fit to the propagation model than the Okumura-Hata model.

Published: September 2021

The idea behind the QC paradigm lies in the information storage capacity in amplitude values that use systems based on Qubits or quantum bits -not in bits-, and in the processing of it when transformations are required to change these amplitudes in a precise and controlled way. Therefore, the description of the states in a computer evolves obeying different algorithms than the known ones: correcting errors and digitizing arbitrarily precise calculations through limited resources. The present documentary research, carried out by the Orion research group in 2018, establishes a state of the art of knowledge in QC oriented to education as a baseline for future research whose development platforms are open source kind.

A methodology based on indexes is established to categorize and subcategorize the QC, as are: fundamentals and background, QC history, concept and operation, companies that implement the QC field, applications, platforms that are managed in QC, architecture, and finally the programming languages. Source databases such as IEEE-Xplore, EBSCO, and websites, were used to illustrate the fundamental concepts and developments that companies have specified in applications using this new paradigm.

Authors: Sánchez-Rivera Félix Andrés , Leguizamón-Páez Miguel Ángel , Larrota-Alférez Jheshua Dannand Jared
Published: September 2021

This article is a review that leads to build a state of knowledge about Multi-Agent Systems based on Selection and Search (ISSA) applied in the search and selection of organ and tissue transplant recipients, emphasizing as a case study the heart, using Geo-location. In particular, this research analyzes technical, scientific and normative aspects of ISSA, between 2007 and 2017, in Europe (Spain) and Latin America (Colombia). A base line of systems based on Artificial Intelligence is thus obtained for the selection and search of transplant recipients, before a possible demand of the List of Persons Waiting for Donation (LED). From the above, solutions can be implemented reducing time in the allocation of organs taking into account their characteristics and compatibility: blood group, size, location criteria, among others, from one to several possible recipients. Finally, a technological solution model for Colombia is proposed.

Perspectives on environmental education, citizenship, and assessment: A case study of elementary school teachers and principals in Israel
Authors: Gan Dafna
Published: September 2021

Environmental education (EE) is recognized as an important way to improve the environmental crisis. It seems that international and national educational assessment and accountability ideas are working against EE. By examining the perspectives of Israeli teachers, who are important change agents in society, this qualitative case study seeks to understand the potential of EE, when paired with citizenship, to foster a more equitable society in the context of the global educational reform movement. The study focuses on EE implementation in two Israeli schools, asking, “How do Israeli elementary school teachers understand EE’s role in fostering citizenship in the context of assessment and accountability?” The findings contribute to the literature by exploring the relationship between EE, assessment, and citizenship. They also suggest that a school’s ontological perspective on knowledge, namely the constructivist approach, enhances pro-environmental behavior, while the positivist approach matches the EE scientific approach that focuses more on assessment. A whole-school approach to EE deepened the active involvement of participants and enhanced their sense of citizenship more than an inquiry-based learning approach. This study recommends integrating the social component of EE and developing action skills for citizenship, taking into consideration the global assessment movement and accountability context.

Ameloblastic fibrodentinoma (AFD) is a rare tumor with an incidence rate of less than 1%. When lesion with the histomorphology of ameloblastic fibroma(AF), which is true neoplasms, form dysplastic dentin, and had been referred to as AFD. It histologically consists of odontogenic ectomesenchyme resembling the dental papilla, epithelial strands, and nests resembling dental lamina and enamel organ with dentin formation. Although newly categorized as an odontoma by the WHO in 2017, this lesion was previously referred to as a rare odontogenic tumor by the WHO in 2005. Objective: We aim to summarize our case with other previous case reports considered to be equivalent to the conventional WHO classification of AFD. Case Report: An 8-year-old girl presented to our hospital complaining of delayed eruption of a tooth. Computed tomography showed an odontoma-like radiopacity in a unilocular radiolucent lesion sized approximately 20 mm. The lesion was extracted under general anesthesia and histopathologically exhibited AFD. Herein, we report a rare case of AFD in the maxilla. Conclusion: Although this lesion deviates from the concept of disease as an odontogenic tumor, it is hoped that clinically sufficient follow-up is required and more similar cases will accumulate as independent tumors, rather than simply being recognized as developmental odontomas

Previous surveys have indicated that the majority of Indonesian children have poor oral health. However, scant information is available on children’s oral health related quality of life (OHRQoL). The purpose of this study was to assess reliability as well as discriminant and convergent validity of Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) Indonesian version. Methods: The Indonesian version of COHIP-SF 19 was developed according to the guidelines for the cross-cultural adaptation process. The instrument was tested among 529 children between 12 – 15 years old who were randomly selected from six junior high schools in Jakarta. The psychometric testing included internal consistency reliability, test-retest reliability, discriminant validity, and convergent validity. Results: Mean age of the participants was 13.3±0.9 years and 54% of the participants were female. The mean COHIP-SF 19 score was 57.8±8.8 and the median was 58 (range 27 – 75). The internal consistency and test-retest reliability was excellent for COHIP-SF 19 score with Chronbach’s alpha 0.83 and intra-class correlation coefficient 0.81. Children with active decay, untreated caries with pulpal involvement, and gingivitis had significantly lower COHIP-SF 19 scores (p-value ≤ 0.030). Correlation between COHIP-SF 19 score, subscale scores and clinical severity as well as self-rated general or oral health were very low to low (rs = 0.04 – 0.27, p-value ≤ 0.028), after adjustment for children’s age and gender. Conclusions: The Indonesian version of COHIP-SF 19 was successfully developed to be used as an OHRQoL instrument for Indonesian school-age children. The internal consistency, test-retest reliability, discriminant validity, and convergent validity of COHIP-SF 19 Indonesian version were confirmed

Kelulut honey or stingless bee honey is a type of honey produced by stingless bees of the Trigona species where the nest is found in living trees. Objective: The aim of this study was to evaluate the cytotoxic potential of Malaysian Kelulut honey by employing MTT assay on a human gingival fibroblast cell line. Methods: Human gingival fibroblast cell line was cultured in minimal essential medium alpha (α-MEM) with 10% foetal bovine serum and 1% penicillin-streptomycin solution in a 5% CO2 incubator at 37°C in a humidified atmosphere. The cells were seeded at a cell density of 5x103 cells/well in a 96-well culture plate for 24 hours. The cells were treated with seven different concentrations (200, 100, 50, 25, 12.5, 6.25, and 3.125mg/ml) of Malaysian Kelulut honey and incubated in a CO2 incubator. The negative control comprised cells treated with growth media alone. The cell viability was assessed using MTT assay at 24, 48, and 72 hours. The test plate was shaken using a microplate shaker and the absorbance of the solution was measured at 570nm using an ELISA reader with the Magellan software. Statistical analysis of the data was carried out using Kruskal-Wallis test and SPSS 24.0.0 for Windows. A p value <0.05 was considered as statistically significant. Results: There was no cytotoxic effect of Malaysian Kelulut honey on HGF-1 based on the MTT assay at different concentrations and at different time points tested as the cell viability was above 70%. The highest percentage of cell viability at all three different durations of treatment were observed at 3.125mg/ml, whereas the lowest cell viability was observed at 200mg/ml of Kelulut honey concentration. However, statistically significant differences were seen between some of the concentrations at various time points. Conclusion: Since the cell viability of HGF-1 treated with Malaysian Kelulut honey was more than 70% at all concentrations ranging from 3.125mg/ml to 200mg/ml at three different time points (24, 48 and 72 hours), Malaysian Kelulut honey can be considered as non-cytotoxic on human gingival fibroblasts based on MTT assay under the present test conditions

Poor working posture among dental practitioners has been known to cause musculoskeletal disorders (MSDs), which are made worse by lengthy procedures and a lack of awareness about the proper working posture. Objectives: To assess the working posture of clinical dental students to determine if interventions were needed to reduce MSDs. Methods: The working postures of 225 clinical dental students were recorded and assessed within 10 minutes into procedures from March-December 2019, using the Rapid Upper Limb Assessment (RULA) method. The results were then statistically analysed using chi-square and Fisher’s exact tests. Results: Of the 225 students observed, 64 (28.4%; 95% CI: 23.1-35.7%) were classified as having RULA scores of 1-2 and 3-4, 141 (62.7%; 95% CI: 58.4- 65.7%) had RULA scores of 5-6 and 19 (8.4%; 95% CI:5.3-12.4%) had RULA scores of 7. Only one student had a RULA score of 1-2, where posture was considered acceptable. The working postures of the students in year 4 (P<0.001) were worse than those of the students in the other clinical years. No significant difference was observed concerning gender variance. Conclusion: Students’ working postures should be evaluated frequently, and other tools, for example, dental loupes, should be provided to help them maintain good working postures

Authors: Nugroho Taufik Eko , Harahap Mohamad Sofyan , Jatmiko Heru Dwi
Published: September 2021

Latar belakang: Nitric oxide (NO) berperan dalam patogenesis terjadinya hipotensi sistemik pada syok septik. Pajanan endotoksin akan menyebabkan peningkatan pelepasan NO yang dipengaruhi oleh aktivasi sitokin proinflamasi. Simvastatin diduga menekan produksi sitokin proinflamasi akibat pajanan lipopolisakarida (LPS),  sehingga pembentukan NO dapat dihambat.Tujuan: Membuktikan pengaruh pemberian simvastatin dosis 0,03 mg, 0,06 mg dan 0,12 mg peroral dapat menyebabkan kadar NO mencit yang diberi lipopolisakarida intraperitoneal menjadi lebih rendah.Metode: Penelitian eksperimental laboratorik dengan desain randomized post test only controlled group pada 20 ekor mencit Balb/c yang disuntik lipoplisakarida intraperitoneal dan simvastatin dosis 0,03 mg; 0,06 mg dan 0,12 mg peroral. Mencit dibagi menjadi 4 kelompok secara random, yaitu K1 sebagai kontrol, K2 yang mendapat simvastatin 0,03 mg, K3 yang mendapat simvastatin 0,06 mg, dan K4 yang mendapat simvastatin 0,12 mg. Pemeriksaan NO diambil dari kultur makrofag intraperitoneal setelah 6 jam pemberian simvastatin dengan metode Griess. Uji statistik yang digunakan adalah parametrik ANOVA dan dilanjutkan uji Posteriori.Hasil: Kadar rerata NO pada kelompok K1(0,680±0,116), K2(0,313±0,136), K3 (0,109±0,005) dan K4(0,091±0,011). Terdapat penurunan yang bermakna kadar NO pada kelompok K2, K3 dan K4 dibanding K1 dengan p <0,05. Tidak terdapat perbedaan yang bermakna antara kadar NO kelompok K2 dengan kelompok K3 dan K4, serta kelompok K3 dibanding K4 (p > 0,05).Simpulan: Simvastatin secara bermakna dapat menyebabkan kadar NO makrofag intraperitoneal mencit yang diinduksi lipopolisakarida menjadi lebih rendah.

Published: September 2021

Latar Belakang: Tindakan bedah definitif payudara banyak dilakukan dengan anestesi umum. Namun, dengan anestesi umum ada sebagian rangsang nyeri yang tidak terhambat ke otak dan medulla spinalis. Anestesi umum juga dikaitkan dengan insidensi mual dan muntah. Beberapa tehnik anestesi regional yang pernah disebutkan dalam literatur untuk operasi payudara antara lain dengan infiltrasi lokal, anestesi epidural torakal dan blok paravertebral torakal. Blok paravertebral torakal merupakan teknik injeksi lokal di samping vertebra torakal yang menyebabkan blokade saraf somatik dan simpatik ipsilateral pada dermatom torakal di atas dan di bawah lokasi injeksi. Trauma pembedahan menyebabkan respon inflamasi lokal dan respon metabolik endokrin sistemik. Respon sistemik setelah pembedahan meliputi peningkatan hormon katabolik seperti katekolamin, kortisol, renin, aldosteron, dan glukagon.Tujuan: Membandingkan pengaruh antara blok paravertebral injeksi tunggal dan multipel terhadap kadar kortisol plasma dan VAS pasien yang dilakukan operasi eksisi biopsi.Metode: Penelitian ini dilakukan pada 20 penderita tumor payudara yang menjalani operasi eksisi biopsi. Pengambilan sampel darah perifer untuk pemeriksaan kortisol pada jam 8 pagi sebelum operasi dan jam 8 pagi besoknya. Nilai VAS diperiksa pada jam ke-0 (saat pasien masuk ruang pemulihan), dan jam ke-24. Penderita dikelompokkan secara random menjadi 2 kelompok. Kelompok M mendapat injeksi multipel dan kelompok T mendapat injeksi tunggal. Dilakukan uji normalitas distribusi kadar kortisol darah dan VAS dengan menggunakan Shaphio-Wilk test. Apabila p>0,05 maka distribusinya disebut normal. Analisis statistik dilakukan untuk menguji perbedaan kelompok dengan pre dan post test group design, signifikan bila p<0,05.Hasil: Data karakteristik sampel penelitian tiap kelompok terdistribusi normal(p>0,05). Kadar kortisol plasma pasca operasi pada kelompok M (224,73 ± 0,73) dan T (234,01 ± 0,84) lebih rendah dibandingkan sebelum operasi pada kelompok M (256,55 ± 0,91) dan T (258,34 ± 0,91) tetapi tidak berbeda bermakna (p>0,05). VAS pasca operasi jam ke-0 pada kelompok M (3,5 ± 0,2) lebih rendah dibanding kelompok T (3,9 ± 0,2) dan berbeda bermakna (p=0,02). VAS pasca operasi jam ke-24 pada kelompok M (3,3 ± 0,7) lebih rendah dibanding kelompok T (3,7 ± 0,7) tetapi tidak bermakna (p=0,388).Kesimpulan: VAS pasca operasi jam ke-0 kelompok M lebih rendah secara signifikan dibanding kelompok T. Tidak didapatkan perbedaan bermakna pada kadar kortisol plasma dan VAS jam ke-24 pasca operasi antara injeksi multipel (M) dan injeksi tunggal (T) pada pasien yang menjalani eksisi biopsi.

The “Jew,” the Nation and Assimilation: The Old Testament and the Fashioning of the “Other” in German and Dutch Protestant Thought
Authors: van der Tol Mariëtta
Published: September 2021

This article discusses a reorientation of supersessionist postures in German and Dutch Protestant reflection on emerging nation states in the nineteenth-century. Historically, Christian thought often othered “the Jew” as the “nascent Christian.” Since the seventeenth-century, Protestant theologians also entertained the possibility of theological othering on the basis of the legalism of the Mosaic covenant, of which ancient biblical Israel and its cultural liturgies were regarded as a token. In the context of the modern nation, German and Dutch Protestant thought entertained this typological othering of biblical nationhood to construct the modern Jew as “Gentile” to the modern nation. As “Gentile,” “the Jew” remains the embodiment of the ultimate other, yet as “nascent Christian,” modern Jews begin to face an unrelenting demand to assimilate. This conundrum contributed to a fundamental tension in the imaginary of the nation, namely between patterns of othering and structures of belonging, echoing far beyond antisemitism, and especially in patterns of othering that are inherent to racism and Islamophobia.

Authors: Gujral Tanya , Subburaj Jeyanthi , Sharma Kiran
Published: September 2021

Objectives

To examine the effects of moderate intensity resistance training with blood flow restriction on muscle strength and forearm girth.

Methods

Total of 39 students enrolled in this study were divided into three groups that is group A (control group), group B and group C. Group A performed exercise training without restrictive pressure, group B and C performed exercise training with 50 and 75 mmHg respectively. Both the outcome measures were evaluated on day 1 and day 12th with the help of digital dynamometer and measuring tape.

Results

Repeated measure ANOVA with Post hoc analysis was done using SPSS software version 20. The result of the study showed significant (p≤0.05) within subject improvement in muscle strength and muscle girth in all the three groups. However, significant improvement in muscle strength was found in between group analysis (p≤0.05).

Conclusions

The results of the study can be concluded as the partial blood flow restriction (50 mmHg) with moderate intensity resistance training resulted in greater handgrip strength than the other two groups. No difference was found in forearm girth among the three groups, however within the group difference was found.
Universal and macro-areal patterns in the lexicon
Authors: Georgakopoulos Thanasis , Grossman Eitan , Nikolaev Dmitry , Polis Stéphane
Published: September 2021

This paper investigates universal and areal structures in the lexicon as manifested by colexification patterns in the semantic domains of perception and cognition, based on data from both small and large datasets. Using several methods, including weighted semantic maps, formal concept lattices, correlation analysis, and dimensionality reduction, we identify colexification patterns in the domains in question and evaluate the extent to which these patterns are specific to particular areas. This paper contributes to the methodology of investigating areal patterns in the lexicon, and identifies a number of cross-linguistic regularities and of area-specific properties in the structuring of lexicons.

Authors: Budak Huseyin , Kara Hasan , Ali Muhammad Aamir , Khan Sundas , Chu Yuming
Published: September 2021

In this work, we introduce the notions about the Riemann-Liouville fractional integrals for interval-valued functions on co-ordinates. We also establish Hermite-Hadamard and some related inequalities for co-ordinated convex interval-valued functions by applying the newly defined fractional integrals. The results of the present paper are the extension of several previously published results.
Photonic crystal nanobeam cavities with lateral fins
Authors: Liu Zhonghe , Chen Yudong , Ge Xiaochen , Zhou Weidong
Published: September 2021

We present the design, fabrication, and characterization of suspended arrays of small volume, high quality factor (Q) silicon nitride photonic crystal nanobeam (PCNB) cavities with lateral nanorod fin structures. By controlling the alignment position of the fins with respect to the air holes, the resonance wavelength and Q-factor of the PCNB cavities can be tuned to realize the desired performance. Measured tunable range of 2 × 104 and 10 nm is achieved for Q-factor and resonance wavelength, respectively, with the highest Q-factor measured at 2.5 × 104. Incorporating such nanorod fins into the nanobeam cavity is demonstrated to provide improved mechanical support, thermal transport, and channels of lateral carrier injection for the suspended PCNB. The proposed PCNB cavities with lateral fins are advantageous for energy efficient, ultra-compact lasers, modulators, filters, and sensors.
Azimuthally and radially polarized orbital angular momentum modes in valley topological photonic crystal fiber

Published: September 2021

Artificially tailoring the polarization and phase of light offers new applications in optical communication, optical tweezers, and laser processing. Valley topological physics provides a novel paradigm for controlling electromagnetic waves and encoding information. The proposed fiber has the inner and outer claddings possessing opposite valley topological phases but the same refractive indices, which breaks through the polarization constraints of the traditional fiber. Robust valley edge states exist at the domain walls between the inner and outer claddings because of bulk edge correspondence. The valley topological fiber modes exhibit the unprecedented radial and azimuthal polarization with high-order azimuthal index. Those topological modes are robust against the disorder of the fiber structure. These results enable guide and manipulate the optical polarization and angular momentum in fiber with high fidelity. The proposed fiber has the potential to become a powerful optical spanner for the application of bio-photonics.

Philosophy of Scientific Malpractice
Authors: Andersen Hanne
Published: September 2021

This paper presents current work in philosophy of science in practice that focusses on practices that are detrimental to the production of scientific knowledge. The paper argues that philosophy of scientific malpractice both provides an epistemological complement to research ethics in understanding scientific misconduct and questionable research practices, and provides a new approach to how training in responsible conduct of research can be implemented.

In the present work, halloysite nano-clay (HNTs) based hydrogel was fabricated and their efficiency for the removal of methylene blue dye was studied. The hydrogel films were prepared with varying amount of halloysite nano-clay via facile solution casting method. Effect of halloysite clay on adsorption performance of composite was investigated. The hydrophobic thermoplastic synthetic polymer, polylactic acid (PLA) was blended with hydrophilic polymer polyvinyl alcohol (PVA) and HNTs to synthesize hydrogels. Swelling behavior and antimicrobial efficiency was also evaluated. The halloysite incorporating films showed excellent antibacterial activity. Swelling capacity of hydrogel with increased halloysite content was reduced due to increased crosslinking among polymer chains. Halloysite incorporated hydrogel exhibited higher adsorption ability as compared to film comprising of only PVA and PLA and dye removal followed pseudo first order kinetics. Film with 0.03 g HNTs rapidly attained adsorption-desorption equilibria and removed the dye completely within 30 min. Results confirmed that synthesized film could be potentially used for the removal of cationic dye and fabricated hydrogel film have promising potential for wastewater treatment since a higher adsorption capacity was observed for halloysite nano-clay incorporated hydrogel.
Oscillatory Correlates of Intentional Forgetting: The Role of Theta and Alpha Power in Item-Method Directed Forgetting
Authors: Scholz Sebastian , Dutke Stephan , Busch Niko A.
Published: September 2021

Results from item-method directed forgetting suggest that individuals are able to intentionally forget processed information. Most research suggests that either selective rehearsal of to-be-remembered or inhibitory control of to-be-forgotten information is accountable for the effects of intentional forgetting. Some research, however, hypothesized that the time to process information mediates the underlying mechanism. To test this hypothesis, the current study investigated associations between oscillatory power in theta (3–7.5 Hz) and alpha frequencies (8–13 Hz) and intentional forgetting in human participants and explored whether or not these mechanisms depended on processing time. Previously, theta power was shown to be associated with the creation of episodic memory traces and alpha power with inhibition. We therefore expected to find associations between these neural signatures and behavioral effects. Consistent with our hypotheses, we revealed increased theta power for to-be-remembered and increased alpha power for to-be-forgotten information and that the effects of activity in both frequency bands were influenced by the time individuals were given for processing the memory cue. These results suggest that not one but two mechanisms, rehearsal and inhibitory control, are accountable for item-method directed forgetting, both with different temporal profiles.
In Game as in Life? Linking Decision-making to Real-world Behavior
Authors: Rubin Mikael , Telch Michael , Dainer-Best Justin
Published: September 2021

Decision-making processes in everyday life are complex. Research on decision-making has focused on self-report or experimental paradigms to understand this process. Recent work has highlighted the potential for complex iterative decision-making frameworks. We developed a simulated decision-making paradigm to assess the relationship between in-game and real-world behaviors and symptoms of depression through exploratory and then pre-registered, confirmatory analyses. Our pre-registered and post-hoc confirmatory analyses highlighted the link between in-game technology use and real-world technology use. We also explored decision-making through transition probabilities to evaluate how specific decisions might unfold over time. The findings emphasized the stability of discrete decision-making in two independent samples. Taken together, these findings suggest that some behavioral patterns appear to be quite stable. Our novel “game” has the potential to provide important insights into decision-making processes and may provide a unique method for identifying and intervening on specific targeted behaviors.
