Published: March 2021

This study aimed to determine problems of preservice teachers on technological pedagogical knowledge skills. The socio-economic transformations taking place in the country indicate the presence of a society’s need for a person who has the ability to set goals and achieve them independently. In this regard, education is faced with the task of forming the personality of the future teacher as a subject capable of diagnosing the process and results of its activities. However, the educational technologies used at the university most often alienate students from educational activities, offering ready-made goals, ways to solve them, and thereby exclude them from the diagnostic process. A change in the modern educational situation actualizes the formation problem of technological pedagogical knowledge skills in a future teacher. The article deals with the development of a scientifically-based system for preparing students for diagnostic activity, which includes theoretical and practical training at the university. The practical significance of the research results lies in the possibility of using the developed methodological recommendations in the practice of training specialists in the field of primary education.

Keywords: Technological pedagogical knowledge, skills, knowledge assessment, preservice teachers, teacher education.

Authors: Fajarini Melati , Rahayu Sri , Setiawan Agus 
Published: March 2021

Introduction: The use of evidence-based practice (EBP) has been demonstrated to increase the quality of patient care. However, the extent to which it is practiced in Indonesia is yet to be determined. It was necessary to develop a means of measuring EBP in order to acquire a profile of the use of EBP in Indonesia. The EBP questionnaire (EBPQ) developed by Upton and Upton was selected in the current study to evaluate the perceptions of healthcare workers regarding their knowledge of, attitudes toward, and practice of EBP. This questionnaire is widely recognized; however, an Indonesian version has not yet been developed. This study aimed to translate the EBPQ developed by Upton and Upton into Indonesian and to evaluate its reliability. Method: WHO framework on how to translate and adapt an instrument was applied. On completion of the forward translation and discussion process, backward translation of the EBPQ was performed, after which it was pretested and finalized. Reliability was tested by testing the questionnaire on 42 nurses at five hospitals in Depok and Jakarta. Result: Four words were changed. All items are valid. The reliability analysis resulted Cronbach’s a of 0.96 (a = 0.92, 0.80, and 0.96 for practice, attitude, and knowledge, respectively. Thus, 24 translated statements determined to be valid and reliable, were included in the final version. Conclusion: The Indonesian translated version of the EBPQ proposed by Upton and Upton was demonstrated to be valid and reliable. Further studies on the perceptions of healthcare workers are warranted.

Published: March 2021

Case:
A newborn presented with necrotic skin lesions and contractures of the right upper extremity. Ultrasonography indicated the presence of a brachiocephalic artery thrombosis, and clinical examination demonstrated a neonatal forearm compartment syndrome. Surgical treatment included decompressive fasciotomy of the right forearm. The right-sided brachiocephalic thrombosis resulted in left hemiplegic cerebral palsy. At the 3-year follow-up, the patient had near-normal function of the right upper extremity. This case has detailed preoperative video and follow-up to illustrate this rare but modifiable condition.

Conclusion:
This case demonstrates a unique cause of neonatal forearm compartment syndrome (brachiocephalic arterial thrombosis) and the results of prompt surgical treatment.
Facies architecture and time stratigraphic relationships of a confined trunk-tributary valley fill and unconfined fluvial system in the backwater of the Turonian Ferron-Notom Delta, Utah, U.S.A.
Authors: Kynaston David , Bhattacharya Janok P. , Singer Brad S. , Jicha Brian R. 
Published: March 2021

ABSTRACTThis paper documents a tidally incised, mudstone-prone tributary valley fill linked to a trunk valley in the backwater limit of the Turonian Notom Delta of the Ferron Sandstone Member, Utah. High-resolution 3D photogrammetry models were used to correlate a 20-m-deep valley between 32 measured sections over a 1 km2 area. A GPS survey and GIS geostatistical tools were used to restore the morphology of the tributary valley. The restored valley floor is interpreted as a surface of tidal erosion, based on the overlying facies and surface morphology. Morphological similarities exist between this tributary valley and modern analogs observed in northern Australia, the Memramcook tributary in the Bay of Fundy, and Pleistocene sediments in the Gulf of Thailand.40Ar/39Ar dating of sanidine crystals using multi-collector mass spectrometry allow for a re-evaluation of depositional rates and timing of 32 fluvial aggradation cycles (FACs) and 9 fluvial-aggradation cycle sets (FAC sets) in this sequence. The new dates show that the entire sequence was deposited in 15 ± 5 kyr, and show that Milankovitch cycles cannot account for the internal complexity of this fluvial stratigraphy, indicating likely autogenic control of the FAC sets. The lateral extent of FACs in floodplain deposits mapped in outcrop are correlated over tens to hundreds of meters, and scale to estimated channel widths reflecting the autogenic control. FAC sets can be correlated for up to 10 km along depositional strike, which suggest controls unrelated to the dynamics of individual channels and may show some elements of allogenic climate-driven processes.
Paynita PermotauricaN. Gen., N. SP., and the Other Dagmaritin Foraminifera from the Changhsingian (Permian) of Southern Turkey: Review of Dagmaritin Phylogeny
Authors: Altıner Demır , Özkan-Altıner Sevınç , Atasoy Serdar Görkem , Şahın Nazıf 
Published: March 2021

ABSTRACTThe name Paynita is proposed for a new dagmaritin genus from the upper Changhsingian (Permian) carbonates of the Southern Biofacies Belt in Turkey. Paynita permotaurica differs from its ancestor Paradagmarita monodi by a hook-shaped fold in the apertural flap terminating systematically against the inner surface of the septal wall to protect the opening from one chamber to the other. It is associated with several species of dagmaritins, belonging to Paradagmarita, Paradagmacrusta, Louisettita, Dagmarita, Danielita, and Bidagmarita. The overall analysis of dagmaritins reveals that the stratigraphic range of the group is from Wordian to Changhsingian. The revised chronostratigraphy in the type area of the genus Sengoerina indicates that this oldest dagmaritin was derived from Globivalvulina cyprica in the Wordian. The first occurrences of genera Dagmarita and Danielita postdate the first occurrence of Sengoerina in the Wordian. Paynita is the last evolutionary step of the Sengoerina-Dagmarita-Crescentia-Paradagmarita lineage characterized by a planar apertural flap whose structure practically remained unchanged during the process of evolution. Paynita is the first genus in this lineage displaying fold in the apertural flap similar to the evolution of Louisettita from Dagmarita.

Published: March 2021

Abstract
Whole genome sequencing (WGS) is able to differentiate closely related Mycobacterium tuberculosis variants within the same transmission cluster. Our aim was to evaluate if this higher discriminatory power may help identify and characterize more actively transmitted variants and understand the factors behind their success. We selected a robust MIRU-VNTR-defined cluster from Almería, Spain (22 cases throughout 2003–2019). WGS allowed discriminating, within the same epidemiological setting, between a successfully transmitted variant and seven closely related variants that did not lead to secondary cases, or were involved in self-limiting transmission (one single secondary case). Intramacrophagic growth of representative variants was evaluated in an in vitro infection model using U937 cells. Growth rates were higher for the actively transmitted variant (range: 5.3–10.7) than for the unsuccessfully transmitted closely related variants (1.5–3.95). Two SNPs, mapping at the DNA binding domain of DnaA and at kdpD ,were found to be specific of the successful variant.
Adaptive Super Twisting Sliding Mode Control With Fractional Order Sliding Surface for Trajectory Tracking of a Mobile Robot
Authors: Ren Huanhuan , Zhang Lizhong , Su Chengzhi 
Published: March 2021

Abstract
This paper presents the position tracking performance of the robot system with uncertainties and external disturbances by using super twisting sliding mode control (STSMC) with fractional order (FO) sliding surface. In this scheme, fractional calculus theory is applied to the design of the sliding surface of STSMC, which can reduce the chattering caused by the switch control action and ensure that the control system has strong robust characteristics and fast convergence. Based on Lyapunov stability theory, the controller ensures the existence of sliding mode of sliding surface in finite time. Moreover, an adaptive STSMC reaching law is adopted. By using the fractional order nonlinear switching manifold and adaptive reaching law, the control performance can be obtained more effectively in sliding mode phase and the reaching phase, respectively. Finally, in order to validate the effectiveness and robustness of the proposed control strategy, the linear PID control strategy and the classical STSMC strategy are designed for comparative analysis, and the numerical calculation is carried out according to the dynamic model to study the position tracking accuracy of the robot under uncertainty and external interference.
Fast Inverse Design of Nanophotonics using Di fferential Evolutionn and Back-Propagation

Published: March 2021

Abstract
Deep learning technology have been used as a new approach for forward simulation and inverse design of nanophotonic structures. Deep learning technology greatly reduces the time of optical simulation and enables us to use back-propagation (BP) algorithm to optimize design parameters. But BP is very sensitive to the initial values and hard to converge to the optimal value for some initial values. In this research, we propose a hybrid optimization strategy that combined differential evolution (DE) with BP algorithm for the inverse design of multilayer nanofilms structures. The proposed method effectively utilizes the global parallel exploration capability of DE and the local exploitation capability of gradient descent based on BP. It can alleviate the sensitivity of the initial values for the BP algorithm and effectively compensates for the slower convergence properties of the DE. The results suggest that the hybrid DE-BP algorithm can greatly speeds up the inverse design process of multilayer nanofilms and can search in a larger parameter space that even exceeds the parameter range of the training dataset that are used to train the forward prediction neural networks.

Published: March 2021

Abstract
Background In the early weeks of September 2018, clusters of oral sores mostly affecting the tongue were reported in three central schools under Tsirang district, Bhutan. A total of 243 students were affected in total as aggregated by the schools in all three central schools. Almost all the affected students’ complaint of burning sensation of the mouth followed by redness depapillation of the tongue. All the affected students have been assessed on the outbreak and nutritional survey was conducted in the schools. Results: Almost all the affected students in all the three schools had complaints of Burning Sensation (n=158) followed by Pain (n=153), Impaired Taste Sensation (n=100) and Intolerance to Spicy Food (n=95). Other complaints such as Fissured Tongue and Depapillation of the dorsum of the tongue accounted to about 16.6% of the total affected students. Nutritional Survey on school diet revealed the school diet not meeting the Recommended Dietary Allowance (RDA) for Vitamin B1 (Thiamin), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine), B9 (Folic Acid), B12 (Cyanocobalamin) and Iron. Conclusions: While some recommendations are provided, the strongest and most effective measures to prevent the outbreak is to improve the school diet with extended green fruits and vegetables in the school’s dietary menu. Laboratory investigation on the content of currently supplied fortified rice in the schools and the Hazard Analysis of the manufacturers of the fortified rice supplied to Bhutan is also suggested with importance.

Published: March 2021

Abstract
Background

Liver diseases have an adverse impact on human’s body and life, and many factors, such as viruses, genes, etc., are closely related to the occurrence and development of liver diseases. This study tries to explore the relationship between liver diseases and one of the genetic polymorphisms (MMP-9-1562 C/T polymorphism) by meta-analysis, to provide basis for the prevention and treatment of liver diseases and to promote the study of the mechanism of liver diseases by the exploration of etiology.
Methods

Relevant literatures from PubMed, EMBASE, Web of Science, CNKI, Chinese biomedical literature database and other databases were searched from building the database to Dec. 2020. Meta-analysis method was adopted and Review Manager 5.3 software was used for analysis.
Results

A total of 7 studies with 1415 cases and 1592 controls were included in this meta-analysis. A significant association between MMP-9-1562 C/T polymorphism and liver diseases in the homozygous and recessive models (TT vs CC: OR = 1.82,95%CI = 1.28–2.59, P = 0.0009; TT vs CT + CC: OR = 1.73,95%CI = 1.24–2.41, P = 0.001). However, no association in heterozygote and dominant models (CT vs CC: OR = 1.05, 95%CI = 0.76–1.45, P = 0.78; TT + CT vs CC: OR = 1.17, 95%CI = 0.82–1.67, P = 0.38).
Conclusions

Our meta-analysis suggested that the TT genotype of MMP-9-1562 C/T polymorphism might be associated with the risk of nonalcoholic fatty liver disease, hepatocellular carcinoma, and primary liver cancer. If these diseases are present, screening genotype of MMP-9 and aggressive treatment of the primary disease is necessary.
Heparanase Modulation by Wingless/INT (Wnt)

Published: March 2021

Abstract
Heparanase is an endo-beta-glucuronidase, the only enzyme in mammals capable of cleaving heparan sulfate/heparin chains from proteoglycans. The oligosaccharides generated by heparanase present extensive biological functions since such oligosaccharides interact with adhesion molecules, growth factors, angiogenic factors and cytokines, modulating cell proliferation, migration, inflammation, and carcinogenesis. However, the regulation of heparanase activity is not fully understood. It is known that heparanase is synthesized as an inactive 65 kDa isoform and that post-translation processing forms an active 50 kDa enzyme. In the present study, we are interested in investigating whether heparinase is regulated by its own substrate as observed with many other enzymes. Wild-type Chinese hamster (Cricetulus griséus) ovary cells (CHO-K1) were treated with different doses of heparin. Heparanase expression was analyzed by Real-time PCR and flow cytometry. Also, heparanase activity was measured. The heparanase activity assay was performed using a coated plate with biotinylated heparan sulfate. In the present assay, a competitive heparin inhibition scenario was set aside. Exogenous heparin trigged a cell signaling pathway that increased heparanase mRNA and protein levels. The Wnt/beta-catenin pathway, judged by TCF-driven luciferase activity, seems to be involved to enhance heparanase profile during treatment with exogenous heparin. Lithium chloride treatment, an activator of the Wnt/beta-catenin pathway, confirmed such mechanism of transduction in vivo using zebrafish embryos and in vitro using CHO-K1 cells. Taken together the results suggest that heparin modulates heparanase expression by Wnt/beta-catenin.

Published: March 2021

Abstract
BackgroundGhana malaria control programme recommends the uptake of five doses of SP during pregnancy following the review of the WHO recommendations in 2012. The uptake of higher doses of SP since the implementation of the new policy in 2016, has been low across the country. The current study determined factors that can be improved to increase uptake of IPTp-SP in malaria endemic regions. MethodsA descriptive cross-sectional study was carried out among women who had just delivered in selected health facilities in the Sekondi-Takoradi Metropolis of Ghana. Participants were enrolled from the lying-in wards of the study facilities after delivery. Data including time of initiating ANC, number of visits, time of first dose of SP and number of doses were collected. ANC books were also reviewed. Logistic and multinomial logistic regression analyses were done to determine respondent factors associated with uptake of IPTp-SP using Stata 15. ResultsOut of the 496 mothers who participated in the study, 370 (74.60%) initiated ANC during the first trimester, 123 (24.80%) during the second, with only three (0.60%) starting during the third trimester. Majority (463/496, 93.35%) made > 4 visits. Uptake of at least one dose of SP was 98.79% (490/496), ≥ 2 doses was 92.75 (460/496), ≥ 3 doses was 80.65% (400/496) and ≥ 4 doses was 40.32% (200/496). Uptake of IPTp 5 was very low (6.65%, 33/490). A unit increase of one ANC visit was associated with 20% higher odds of receiving 3-4 doses of SP with respect to receiving 1-2 doses (p<0.001). The probability of receiving 5 or more doses of SP with respect to 1-2 doses was 26% higher with a unit increase of one ANC visit. Conclusion Uptake of 3-4 doses and ≥ 5 doses of SP were associated with making more ANC visits. Encouraging and motivating expectant mothers to make more ANC visits can improve uptake of ≥ 5 doses of SP.

Abstract
Calixarenes, which have a great place in supramolecular chemistry, has become the most prominent macrocyclic compounds in synthetic organic chemistry due to their easy synthesis and functionalization. In this study, p-tert-butyl calix[4]arene dihydrazide derivative was synthesized and then reacted with 3-oxo-3,4-dihydro-2H-benzo[b][1, 4] thiazin-2-ylideneacetyl chloride to prepare new calixarene based chromophore compound 4. The structure of the synthesized compound was elucidated by spectroscopic methods such as 1H-NMR 13C-NMR and FT-IR spectroscopy. Chromogenic and fluorescence properties of compound 4 were evaluated. It was observed from both studies that compound 4 was Co2+ selective and shows fluorescence Switched-off behavior. Stoichiometry, binding constant and the detection limit was calculated. The stoichiometry between compound 4 and Co2+ was found to be 1:1. The binding constant value (K) was calculated as 666.67 M− 1 using Benesi–Hildebrand equation, while the detection limit for Co2+ ion was calculated as 0.0465 µM.
