Published: September 2020

Pendidik menjadi citra penting dalam dunia pendidikan, sehingga keberhasilan lembaga pendidikan dalam mencetak anak didiknya tidak terlepas dari eksistensi pendidik yang memiliki sifat-sifat pendidik yang baik disamping kemampuan skillnya. Al-Qur’an banyak berbicara tentang pendidik yang siap mengantarkan pada ranah kehidupan yang lebih baik. Pendidik sebagai ujung tombak yang bisa merobah manusia baik dari aspek budaya, sosial, dan agama. Berkaitan dengan masalah tersebut, akan dibahas dalam penelitian ini berbagai asumsi yang diambil dari sumber utama dalam agama Islam yakni Al-Qur’an. Dalam Al-Qur’an banyak sekali membahas tentang pendidik. Metode yang digunakan dalam penelitian ini adalah metode dokumentasi dengan jenis penelitian kalitatif, penganalisaan data lebih difokuskan pada penelitian perpustakaan (library research), yaitu Al-Qur’an sebagai referensi primer datanya, dan dibantu dengan buku-buku lain yang mendukung sebagai referensi sekunder dari beberapa pemikiran para ahli dan tokoh-tokoh pendidikan tentang tema pendidik. Teknik analisa dalam penelitian ini adalah teknik content analysis. Penelitian ini bertujuan untuk mengetahui tentang berbagai teori tentang pendidik (guru) dalam perspektif Al-Qur’an. Dari hasil penelitian telah ditemukan beberapa hal diantaranya pendidik dalam perspektif Al-Quran sebagai berikut: (1) Allah SWT. Allah sebagai pendidik utama yang menyampaikan kepada para Nabi berupa berita gembira untuk disosialisasikan kepada umat manusia, (2) Kedudukan Nabi sebagai pendidik atau guru yang langsung ditunjuk oleh Allah SWT, (3) Kedudukan orang tua sebagai pendidik anak-anaknya, (4) kebanyakan orang yang tidak terkait langsung dengan nasabnya terhadap anak didiknya.

Published: September 2020

Working outside can be harder than inside; one may be physically more active, regularly battling against the elements and often more alert – watchful for potential dangers. Overall education out of doors is physically and mentally taxing. We have to be convinced all the effort is for a good reason (Bilton, 2010, p. 12). The researchers applied the mixed method with covergent parallel design (Creswell, 2016). The results showed that 1) The initial description of prosocial behaviour of young children in Joy Kids Kindergarten, Mangasa Subdistrict, Tamalate Makassar District, showed that teachers paid attention to improve and look for activities in the form of play so that things that were worse towards prosocial behaviour of children could be avoided. 2) The traditional game-based outdoor learning module produced has been accepted from the results of an assessment of the utility, feasibility and accuracy, carried out by two experts in the field of education and an education practitioner. 3) The traditional game-based outdoor learning module that is produced affects the development of prosocial behaviour of young children. Based on the validator’s evaluation, it is declared valid to be used, its practical value is feasible to be used in the field without the need for revision, and all the devices previously presented can be declared valid for use.
Beyond Beta-Convergence: Convergence in Differences and its Application to the Russian Regions
Authors: Carvelli Gianni
Published: September 2020

The purpose of this paper is to propose a new empirical model capable of highlighting some aspects of cross-economy convergence which cannot be caught by the popular beta-convergence and sigma-convergence models. The idea is to analyse the growth of the economies as a function of the distance between the observed output per capita and the average output per capita within the sample, separating the behaviour of poorest and richest economies. After its specification, I applied the model to the case of the Russian regions over the period 1995-2015 using the fixed-effect estimator. The results show that, although the existence of a significant beta-convergence process, there is a lack of convergence in differences. When the differences between regional and national output per capita are negative, a positive and significant relationship between growth and levels emerges. Such a relationship turns to be negative and non-significant when the differences are positive, therefore denoting weak non-linearity between growth rate and level of output per capita. Similar findings have been found for labor productivity.

Published: September 2020

The aim of this study was to evaluate the response of Galinsoga parviflora to different doses of the herbicide Chwastox Turbo 340 SL [2-methyl-4- chlorophenoxyacetic acid (MCPA) + dicamba] used alone and with an adjuvant. The study was conducted on the spring barley cultivar ‘Suweren.’ During the tillering stage of spring barley, a weed control treatment was applied using Chwastox Turbo 340 SL at a rate of 100% and at rates reduced by 33% and 50%, and was applied either alone or with an oil adjuvant. Plots without herbicide and adjuvant application were the control treatment. The present study showed that in spring barley the largest plants of G. parviflora, which produced the highest number of branches, flower heads, and achenes, occurred in the control treatment where no herbicide and adjuvant were applied. Morphology, productivity, and biomass were not found to vary greatly between G. parviflora plants occurring in the plots where the reduced rates of Chwastox Turbo 340 SL and in those where the manufacturer’s recommended rate were applied. The number of achenes produced by G. parviflora was positively correlated with plant height and negatively with plant biomass. The germination capacity of G. parviflora diaspores was not significantly different between the herbicide protection treatments.

Review in Autism and Epilepsy
Authors: AlKhateeb Mashael , AlDhalaan Hesham
Published: September 2020

Autism is a neurodevelopmental disorder of undefined etiology characterized by social, communication deficits, and restricted interests/repetitive or isolated behaviors. The determination of autism is made in early life as the patients create unusual or decreased social interaction and communication, together with stereotypic movement. In most patients, a delay in verbal and nonverbal communication is watched, whereas a few patients never accomplish valuable language. Patients with autism and epilepsy may develop any type of seizure and maybe all type of seizures. Interestingly, not absolutely understood relationship between each and a lot of research in progress concerning these relations. In patients with autism, some they do not develop seizures; however, abnormal paroxysmal electroencephalographic “EEG” activity can be seen in up to 30%. For that reason, important investigation of patients with autistic spectrum disorders, and any kids with language regression, should always include sleep recording EEG in order to exclude acquired epileptic aphasia (Landau-Kleffner syndrome). The complex relationship between autism and epilepsy provides a bridge to further knowledge of shared neuronal networks for both the autisms and the epilepsies We review the literature to elucidate the relationships between epilepsy and autism.

Published: September 2020

For the non-Japanese native speakers, including foreigner Japanese learners, watching a Japanese advertisement commercial (CM) can be entertaining due to their unique language and visual presentation. There are some Japanese commercials based on display, for example, the 2D advertisements in magazines or posters and the 3D video-based advertisements accompanied by side comments that can always be seen on YouTube videos. This research is based on Japanese commercials (CMs), in the form of YouTube videos, with the same product types but showing gender differences for men and women. Thus, the main research objective is to examine the structure and texture of Japanese commercials (CMs) in terms of how they market the same product type for both men and women. This research has find that most of the Japanese advertisements for men’s products use a more straightforward style of speaking with an opening and closing commercial structure, and there is a short description of the commercial content. Advertisements for women’s products, meanwhile, are more varied in their opening, closing, and content, as well as in the product introduction and narration. The tenses used in men’s products usually contain present tenses and imperative sentences, which are also prominent. While some advertisers typically use the present tenses for women’s products as well as men’s products, they also use past tenses and different Japanese dictionary formats. Proper sentences also used in the advertisements for women’s products. As for lexicon, or word choice, used for men’s products, only zo and ore are used. The lexicon in women’s products, meanwhile, is more varied with kashira, wa, wayo, wane, no, noyo, none, koto, and kotoyo that being used. For advertisements with high selling power, the structure comprises just an opening and closing, and they are more straightforward and less wordy.

Research on Polling Control System in Wireless Sensor Networks
Authors: Yang Zhijun , Mao Lei
Published: September 2020

To solve the problem of multi-priority and multi-business tasks in wireless sensor networks, a two-level polling control system is proposed based on the basic polling system. The system divides the sites into ordinary sites and high-priority site according to business priorities. The ordinary sites use gated services, and the high-priority sites use exhaustive services. The mathematical model of the system is established by using the method of Markov chain and probability generating function, and the important parameters such as query period, throughput, average queue length and average delay are obtained. The simulation results are approximately equal to the theoretical calculation results, which shows that the theoretical analysis method is correct and effective. While distinguishing priority services, the system ensures the delay of users and improves the quality of service of the polling system.

Authors: Ivanov Antoni , Stoynov Viktor , Angelov Kliment , Stefanov Radostin , Atamyan Dimitar , Tonchev Krasimir , Poulkov Vladimir
Published: September 2020

Deployment of practical Internet of Things (IoT) in the context of 5G can be hindered by substantial interference and spectrum limitations, especially in the unlicensed frequency bands. Due to the high density of such devices in indoor scenarios, the need for interference characterization which facilitates more effective spectrum utilization is further emphasized. This chapter studies the influence of diverse scenarios for the dense placement of interferers on the spectrum occupancy through the use of 3D interference maps for two popular IoT technologies—LoRa and Wi-Fi. The experiments are performed with software-defined radio (SDR) platforms in real time and an automated positioning tool which provides the measurements to characterize the interference in 3D space. The findings demonstrate a nonuniform character of the interference and the significant impact of fading within the width, height, and length of the examined area. They suggest the role of dynamic relocation for realistic IoT scenarios.
Abnormal Ubiquitination of Ubiquitin-Proteasome System in Lung Squamous Cell Carcinomas
Authors: Zhan Xianquan , Lu Miaolong
Published: September 2020

Ubiquitination is an important post-translational modification. Abnormal ubiquitination is extensively associated with cancers. Lung squamous cell carcinoma (LUSC) is the most common pathological type of lung cancer, with unclear molecular mechanism and the poor overall prognosis of LUSC patient. To uncover the existence and potential roles of ubiquitination in LUSC, label-free quantitative ubiquitomics was performed in human LUSC vs. control tissues. In total, 627 ubiquitinated proteins (UPs) with 1209 ubiquitination sites were identified, including 1133 (93.7%) sites with quantitative information and 76 (6.3%) sites with qualitative information. KEGG pathway enrichment analysis found that UPs were significantly enriched in ubiquitin-mediated proteolysis pathway (hsa04120) and proteasome complex (hsa03050). Further analysis of 400 differentially ubiquitinated proteins (DUPs) revealed that 11 subunits of the proteasome complex were differentially ubiquitinated. These findings clearly demonstrated that ubiquitination was widely present in the ubiquitin-proteasome pathway in LUSCs. At the same time, abnormal ubiquitination might affect the function of the proteasome to promote tumorigenesis and development. This book chapter discussed the status of protein ubiquitination in the ubiquitin-proteasome system (UPS) in human LUSC tissues, which offered the scientific data to elucidate the specific molecular mechanisms of abnormal ubiquitination during canceration and the development of anti-tumor drugs targeting UPS.
The Simplification of Customs Formalities: The Role of the Authorized Economic Operator (AEO) in Vietnam and in the EU
Authors: Torello Alessandro
Published: September 2020

Customs clearance operations of goods can be facilitated if importers, forwarders, or logistics operators have obtained the status of Authorized Economic Operator (AEO). The simplification of customs formalities, as well as a lower number of document-based customs controls and of physical inspections, speed up the international trade flows and reduce the delivery time of goods. The World Customs Organization (WCO) has promoted the implementation of standardized procedures since 1970s. On this matter, the WCO adopted the Kyoto Convention in 1974 and the Revised Kyoto Convention (RKC) in 1999. The article analyzes the role of the AEO status in Vietnam and in the European Union, and the opportunities of customs cooperation between Vietnam and the European Union, taking into consideration the Free Trade Agreement (EVFTA) which entered into force on August 1, 2020.

How the brain controls the need and acquisition of recovery sleep after prolonged wakefulness is an important issue in sleep research. The monoamines serotonin and dopamine are key regulators of sleep in mammals and in Drosophila. We found that the enzyme arylalkylamine N-acetyltransferase 1 (AANAT1) is expressed by Drosophila astrocytes and specific subsets of neurons in the adult brain. AANAT1 acetylates monoamines and inactivates them, and we found that AANAT1 limited the accumulation of serotonin and dopamine in the brain upon sleep deprivation (SD). Loss of AANAT1 from astrocytes, but not from neurons, caused flies to increase their daytime recovery sleep following overnight SD. Together, these findings demonstrate a crucial role for AANAT1 and astrocytes in the regulation of monoamine bioavailability and homeostatic sleep.

Published: September 2020

The underlying cell types mediating predisposition to obesity remain largely obscure. Here, we integrated recently published single-cell RNA-sequencing (scRNA-seq) data from 727 peripheral and nervous system cell types spanning 17 mouse organs with body mass index (BMI) genome-wide association study (GWAS) data from >457,000 individuals. Developing a novel strategy for integrating scRNA-seq data with GWAS data, we identified 26, exclusively neuronal, cell types from the hypothalamus, subthalamus, midbrain, hippocampus, thalamus, cortex, pons, medulla, pallidum that were significantly enriched for BMI heritability (p<1.6×10−4). Using genes harboring coding mutations associated with obesity, we replicated midbrain cell types from the anterior pretectal nucleus and periaqueductal gray (p<1.2×10−4). Together, our results suggest that brain nuclei regulating integration of sensory stimuli, learning and memory are likely to play a key role in obesity and provide testable hypotheses for mechanistic follow-up studies.

Most therapeutic candidates for treating attention-deficit hyperactivity disorder (ADHD) have focused on modulating the dopaminergic neurotransmission system with neurotrophic factors. Regulation of this system by transcranial direct current stimulation (tDCS) could contribute to the recovery of cognitive symptoms observed in patients with ADHD. Here, male spontaneously hypertensive rats (SHR) were subjected to consecutive high-definition tDCS (HD-tDCS) (20 min, 50 μA, current density 63.7 A/m2, charge density 76.4 kC/m2) over the prefrontal cortex. This treatment alleviated cognitive deficits, with an increase in tyrosine hydroxylase and vesicular monoamine transporter two and significantly decreased plasma membrane reuptake transporter (DAT). HD-tDCS application increased the expression of several neurotrophic factors, particularly brain-derived neurotrophic factor (BDNF), and activated hippocampal neurogenesis. Our results suggest that anodal HD-tDCS over the prefrontal cortex may ameliorate cognitive dysfunction via regulation of DAT and BDNF in the mesocorticolimbic dopaminergic pathways, and therefore represents a potential adjuvant therapy for ADHD.

Despite the benefits of standardization, the customization of Software as a Service (SaaS) application is also essential because of the many unique requirements of customers. This study, therefore, focuses on the development of a valid and reliable software customization model for SaaS quality that consists of (1) generic software customization types and a list of common practices for each customization type in the SaaS multi-tenant context, and (2) key quality attributes of SaaS applications associated with customization. The study was divided into three phases: the conceptualization of the model, analysis of its validity using SaaS academic-derived expertise, and evaluation of its reliability by submitting it to an internal consistency reliability test conducted by software-engineer researchers. The model was initially devised based on six customization approaches, 46 customization practices, and 13 quality attributes in the SaaS multi-tenant context. Subsequently, its content was validated over two rounds of testing after which one approach and 14 practices were removed and 20 practices were reformulated. The internal consistency reliability study was thereafter conducted by 34 software engineer researchers. All constructs of the content-validated model were found to be reliable in this study. The final version of the model consists of 6 constructs and 44 items. These six constructs and their associated items are as follows: (1) Configuration (eight items), (2) Composition (four items), (3) Extension (six items), 4) Integration (eight items), (5) Modification (five items), and (6) SaaS quality (13 items). The results of the study may contribute to enhancing the capability of empirically analyzing the impact of software customization on SaaS quality by benefiting from all resultant constructs and items.
Microbiomes of fish, sediment and seagrass suggest connectivity of coral reef microbial populations

Published: September 2020

The benthic environments of coral reefs are heavily shaped by physiochemical factors, but also the ecological interactions of the animals and plants in the reef ecosystem. Microbial populations may be shared within the ecosystem of sediments, seagrasses and reef fish. In this study, we hypothesize that coral reef and seagrass environments share members of the microbial community that are rare in some habitats and enriched in others, and that animals may integrate this connectivity. We investigated the potential connectivity between the microbiomes of sediments, seagrass blades and roots (Syringodium isoetifolium), and a seagrass-specialist parrotfish (C. spinidens) guts in reef areas of Fiji. We contrasted these with sediment samples from the Florida Keys, gut samples from surgeonfish (A. nigricauda, Acanthurinae sp. unknown, C. striatus), and ocean water microbiomes from the Atlantic, Pacific and Indian Oceans to test the robustness of our characterizations of microbiome environments. In general, water, sediment and fish gut samples were all distinct microbiomes. Sediment microbiomes were mostly similar between Fiji and Florida, but also showed some regional similarities. In Fiji, we show connectivity of a shared microbiome between seagrass, fish and sediments. Additionally, we identified an environmental reservoir of a surgeonfish symbiont, Epulopiscium. The connection of these ecosystem components suggests that the total microbiome of these environments may vary as their animal inhabitants shift in a changing ocean.

Background

Deformed wing virus (DWV) is a virulent virus that causes honeybee disease. DWV can exist as a latent infection in honeybees, outbreak into epidemics, and cause serious damage to beekeeping cross the world, including Vietnam.

Methods

The two DWV strains circulating in Vietnamese honeybee, Apis cerana, were first isolated from adult honeybees in North Vietnam (DWV-NVN) and South Vietnam (DWV-SVN). Their complete nucleotide sequences were determined, aligned, and compared with other DWV strains.

Results

The two Vietnamese DWV strains comprised 10,113 bp and contained a large single open reading frame (ORF) of 2,893 amino acids, initiating at nucleotide 1,130 and terminating at nucleotide 9,812. Multiple nucleotide sequence alignment between these two DWV-VN strains and DWV strains in A. mellifera was performed. The DWV-VN strains showed a low genetic identity (from 91.4% to 92.0%) with almost of these strains, but lower identities (89.2% and 89.4%) with UK2 and (89.6%) with the China2 strain. Low identities (91.7% and 91.9%) were also observed between the China3 strain (in A. cerana) and the DWV-VN strains, respectively. The deduced amino acid sequence alignment showed high genetic similarities (97.0%–97.9%) when the USA1, Chile, Italy1, France, UK1, UK2, Japan, Korea2, China1, China2 and China3 strains were compared to the DWV-VN strains. This ratio was 96.7% and 96.8% when the Korea1 strain was compared to the DWV-SVN and DWV-NVN strains, respectively. Numerous amino acid substitutions were identified in the L, VP3, and RdRp sequences. Notably, we observed six substitutions positioned at amino acids 27 (E > I), 98 (S > T), 120 (A > V), 153 (M > T), 170 (D > F), and 174 (Y > F) in the L protein, two amino acid changes at positions 980 (S > A) and 1032 (E > T) in VP3, and one amino acid change at position 2627 (R > C) unique to the DWV-VN strains. Phylogenetic analysis based on complete genome sequences, RdRp sequences and Simplot analysis indicated that there was a significant difference between DWV-VN strains in A. cerana and DWV strains in A. mellifera. The results suggested that the genetic variations of the DWV-VN strains in A. cerana help them to adapt geographical conditions and may lead to change the viral pathogenicity of DWV-VN strains.

Published: September 2020

Background

Breast cancer is a heterogeneous disease. Compared with other subtypes of breast cancer, triple-negative breast cancer (TNBC) is easy to metastasize and has a short survival time, less choice of treatment options. Here, we aimed to identify the potential biomarkers to TNBC diagnosis and prognosis.

Material/Methods

Three independent data sets (GSE45827, GSE38959, GSE65194) were downloaded from the Gene Expression Omnibus (GEO). The R software packages were used to integrate the gene profiles and identify differentially expressed genes (DEGs). A variety of bioinformatics tools were used to explore the hub genes, including the DAVID database, STRING database and Cytoscape software. Reverse transcription quantitative PCR (RT-qPCR) was used to verify the hub genes in 14 pairs of TNBC paired tissues.

Results

In this study, we screened out 161 DEGs between 222 non-TNBC and 126 TNBC samples, of which 105 genes were up-regulated and 56 were down-regulated. These DEGs were enriched for 27 GO terms and two pathways. GO analysis enriched mainly in “cell division”, “chromosome, centromeric region” and “microtubule motor activity”. KEGG pathway analysis enriched mostly in “Cell cycle” and “Oocyte meiosis”. PPI network was constructed and then 10 top hub genes were screened. According to the analysis results of the Kaplan-Meier survival curve, the expression levels of only NUF2, FAM83D and CENPH were associated with the recurrence-free survival in TNBC samples (P < 0.05). RT-qPCR confirmed that the expression levels of NUF2 and FAM83D in TNBC tissues were indeed up-regulated significantly.

Conclusions

The comprehensive analysis showed that NUF2 and FAM83D could be used as potential biomarkers for diagnosis and prognosis of TNBC.
