Background
The novel coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread across the world. The aim of our study was to characterize mild courses and to determine the antibody status for these patients.

Methods
We initiated an appeal for convalescent plasma donations. 615 people contacted us, and we ultimately included 426 in our analyses, in whom it was possible to assume COVID-19 based on detection of specific SARS-CoV-2 antibodies or virus detection during the disease using RT-PCR.

Results
The median duration of the disease was 12 days and the most common symptoms were fatigue, cough and olfactory and gustatory dysfunction. Anti-SARS-CoV-2 IgG was detected in 82.4% of the persons and IgA antibodies were found in 73.9%. In 10.8%, no antibodies were detectable despite a positive RT-PCR result during the disease. Nevertheless, of 24 persons with asymptomatic courses of COVID-19, antibodies against SARS-CoV-2 could be detected in 23 (96%). Furthermore, there was a correlation between the duration of the disease and the detection of IgG antibodies. In addition, a correlation between the determined IgG antibodies and neutralizing antibodies was shown.

Conclusion
In this study, we were able to describe mild COVID-19 courses and determine antibody statuses for them. It could be shown that, despite SARS-CoV-2 detection during the disease, not all individuals developed antibodies or their level of antibodies had dropped below the detection limit shortly after the end of the disease. The extent to which immunity to re-infection is given in persons with undetectable antibodies (IgG, IgA) needs to be investigated in future studies.

PENGENDALIAN PERSEDIAAN PROBABILISTIK PRODUK SUBSTITUSI DENGAN PERMINTAAN SEBAGAI FUNGSI HARGA
Authors: Nafisah Laila , Sutrisno Sutrisno 
Published: February 2021

Kamara Living merupakan suatu unit usaha yang bergerak dalam penjualan kebutuhan sehari-hari. Salah satu produk yang populer adalah sarung bantal. Sarung bantal yang ditawarkan memiliki beberapa desain motif dan jenis yang berbeda. Permintaan akan produk sarung bantal tidak menentu antara satu desain dengan desain yang lain. Ketika desain tertentu persediaannya habis, perusahaan akan menawarkan desain lain dari jenis kain yang sama. Jika konsumen tidak bersedia maka terjadi kehilangan penjualan. Ketika persediaan berlebih, perusahaan akan memberikan harga promosi untuk mendongkrak tingkat penjualannya. Jika ini dibiarkan terus-menerus, tentu saja perusahaan akan mengalami penurunan keuntungan. Pada makalah ini dikembangkan model persediaan dengan mempertimbangkan produk substitusi dengan permintaan sebagai fungsi harga yang bertujuan untuk meminimasi total biaya persediaan. Penyelesaian model yang dilakukan mampu menghasilkan solusi kuantitas pemesanan dan titik pemesanan yang optimal. Validasi model dilakukan dengan membandingkan hasil dari model yang dikembangkan terhadap kondisi riil. Selain itu juga dilakukan analisis sensitivitas terhadap parameter-parameter yang berpengaruh. Abstract[Product-substitution Inventory Model with Demand depend on Price] Kamara Living is a business unit engaged in selling daily stuff. One popular product is pillowcases. The pillow cover offered has several different motif designs and types. The demand for pillowcases is uncertain between one design and another. When a stockout occurs for a particular design, the company will offer another design of the same type of fabric. If consumers are not willing, there will be lost sales. When there is overstock, the company will provide promotional prices to increase sales levels. If this is allowed to continue, of course the company will experience a decline in profits. In this paper, an inventory model is developed by considering substitute products with demand as a price function that aims to minimize the total cost of inventory. Completion of the model carried out is able to produce optimal order quantity and order point solutions. Model validation is done by comparing the results of the models developed against real conditions. In addition, a sensitivity analysis was carried out on the influential parameters.Keywords: Inventory Models; Product Substitution; Demand Depend on Price
The WD40-Repeat Protein WDR-20 and the Deubiquitinating Enzyme USP-46 Promote Cell Surface Levels of Glutamate Receptors

Reversible modification of AMPA receptors (AMPARs) with ubiquitin regulates receptor levels at synapses and controls synaptic strength. The conserved deubiquitinating enzyme (DUB) ubiquitin-specific protease-46 (USP-46) removes ubiquitin from AMPARs and protects them from degradation in bothCaenorhabditis elegansand mammals. Although DUBs are critical for diverse physiological processes, the mechanisms that regulate DUBs, especially in the nervous system, are not well understood. We and others previously showed that the WD40-repeat proteins WDR-48 and WDR-20 bind to and stimulate the catalytic activity of USP-46. Here, we identify an activity-dependent mechanism that regulates WDR-20 expression and show that WDR-20 works together with USP-46 and WDR-48 to promote surface levels of theC. elegansAMPAR GLR-1.usp-46,wdr-48, andwdr-20loss-of-function mutants exhibit reduced levels of GLR-1 at the neuronal surface and corresponding defects in GLR-1-mediated behavior. Increased expression of WDR-20, but not WDR-48, is sufficient to increase GLR-1 surface levels in anusp-46-dependent manner. Loss ofusp-46,wdr-48, andwdr-20function reduces the rate of local GLR-1 insertion in neurites, whereas overexpression ofwdr-20is sufficient to increase the rate of GLR-1 insertion. Genetic manipulations that chronically reduce or increase glutamate signaling result in reciprocal alterations inwdr-20transcription and homeostatic compensatory changes in surface GLR-1 levels that are dependent onwdr-20. This study identifieswdr-20as a novel activity-regulated gene that couples chronic changes in synaptic activity with increased local insertion and surface levels of GLR-1 via the DUB USP-46.SIGNIFICANCE STATEMENTDeubiquitinating enzymes (DUBs) are critical regulators of synapse development and function; however, the regulatory mechanisms that control their various physiological functions are not well understood. This study identifies a novel role for the DUB ubiquitin-specific protease-46 (USP-46) and its associated regulatory protein WD40-repeat protein-20 (WDR-20) in regulating local insertion of glutamate receptors into the neuronal cell surface. This work also identifies WDR-20 as an activity-regulated gene that couples chronic changes in synaptic activity with homeostatic compensatory increases in surface levels of GLR-1 via USP-46. Given that 35% of USP family DUBs associate with WDR proteins, understanding the mechanisms by which WDR proteins regulate USP-46 could have implications for a large number of DUBs in other cell types.

Published: February 2021

BACKGROUND AND OBJECTIVES:
In children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, virological characteristics and correlation with disease severity have not been extensively studied. The primary objective in this study is to determine the correlation between SARS-CoV-2 viral load (VL) in infected children with age, disease severity, and underlying comorbidities.

METHODS:
Children &lt;21 years, screened for SARS-CoV-2 at the time of hospitalization, who tested positive by polymerase chain reaction were included in this study. VL at different sites was determined and compared between groups.

RESULTS:
Of the 102 children included in this study, 44% of the cohort had asymptomatic infection, and children with &gt;1 comorbidity were the most at risk for severe disease. VL in children with symptomatic infection was significantly higher than in children with asymptomatic infection (3.0 × 105 vs 7.2 × 103 copies per mL; P = .001). VL in the respiratory tract was significantly higher in children &lt;1 year, compared with older children (3.3 × 107 vs 1.3 × 104 copies per mL respectively; P &lt; .0001), despite most infants presenting with milder illness. Besides the respiratory tract, SARS-CoV-2 RNA was also detectable in samples from the gastrointestinal tract (saliva and rectum) and blood. In 13 children for whom data on duration of polymerase chain reaction positivity was available, 12 of 13 tested positive 2 weeks after initial diagnosis, and 6 of 13 continued to test positive 4 weeks after initial diagnosis.

CONCLUSIONS:
In hospitalized children with SARS-CoV-2, those with &gt;1 comorbid condition experienced severe disease. SARS-CoV-2 VL in the respiratory tract is significantly higher in children with symptomatic disease and children &lt;1 year of age.

This article is prepared to investigate the impacts of Cuminum cyminum essential oil (CEO), NaCl, bile salts, and their combinations on the viability of Lactobacillus casei in probiotic yogurt.The water distillation method was used to extract the CEO, and GC/MS was used to determine its constituents. Then, the CEO’s antibacterial activity, together with NaCl and bile salts, was investigated via the microdilution technique by determining the minimum inhibitory concentration (MIC) against L. casei. Further, the stress effects of 50% MIC on CEO, NaCl, and bile salts were examined by comparing the stress treatments with the control in terms of the L. casei population, pH, acidity, and syneresis percentage in probiotic yogurt during storage in the refrigerator for 28 days.According to the results, the L. casei population and pH decreased in all the treatments during the storage time, such that the intensity of the decrease in the control and CEO treatments was lesser than in other stress treat-ments (P<0.05). The acidity and percentage of syneresis during the storage time increased for all the treatments, with the increase being less in control and CEO than in the other stress treatments (P<0.05). The control and CEO treatments scored the highest in the sensory evaluation (P<0.05).Applying stresses below the MIC resulted in the survival of L. casei in the recommended amount (105–106 CFU mL–1) in the probiotic yogurt until the end of 28 days.
A mesoscale numerical approach to predict damage behavior in concrete basing on phase field method
Authors: Quan Nguyen Hoang , Viet Tran Bao , Tung Nguyen Thanh 
Published: February 2021

In this paper, we develop a numerical approach to simulate the 2D complex damage and fracture process of quasi-brittle concrete materials. Based on the phase field theory for the case of elastic isotropic multicomponent materials and the generation process based upon Monte Carlo’s simulation method, we construct a numerical procedure to solve complex damage thermodynamic problems. The diffusive phase field variable obtained from this calculation can be used to represent the crack nucleation and propagation within 2D complex mesostructure. Some factors that affect the numerical result (type of crack density function and type of split decomposition of strain energy) are accounted to make the predictions more accurate for the case of concrete material. Some new numerical examples are provided to show the usefulness of the approach.

Ineffectiveness of operational of tithe collecting agency related to the aspects of administration, distributing, monitoring or in evaluating the tithe has become the factor of this condition. In other word, it can be assumed that the organizational system and management of tithe is still classical, consumptive and lacking of significant social impact. Bassed on that assumption, the role of government is demmed essential in coping with the issue. Through the tithe collecting agency either in local or in national level, it is espected the management of tithe collection can be optimally down. Meanwhile, Baznas in Banjarmasin City is the object of this reseach in which, according to the writer, this institution has played its rule quite well in the attempt of realizing the laws about the management of tithe (zakat) both in collecting, distributing, and using the tithe and in the attempt of developing the people economic through the prorams of Revolving Loan Fund given by Baznas of Banjarmasin City that can influence the development of the Mustahiq economic trough it recently is not fulfilled maximally.

Introduction: Anxiety symptoms in young children can have negative consequences such as the deterioration of family and interpersonal functioning, and may lead to the development of an anxiety disorder; therefore, the importance of prevention.
Objective: The aim of this study was to evaluate the effectiveness of the Fun FRIENDS program in the reduction of children’s anxiety symptoms and the promotion of emotional and behavioral competences as a protective factor in a sample of Mexican children.
Methodology: The participants included 49 children from the first grade at elementary school along with their teachers. The program was implemented by teachers as twelve consecutive one-week sessions conducted in the classroom. The outcome was measured with a pretest-posttest quasi-experimental design. Measures included the Preschool Anxiety Scale (PAS), for parents, Behavioral and Emotional Rating Scale (BERS-2), for parents, and Strengths and Difficulties Questionnaire (SDQ), for parents and teachers.
Results: Findings showed a decrease in the subscale of separation anxiety of the PAS, an increase in the interpersonal, intrapersonal and affective strengths subscales of the BERS-2, and an increase in prosocial behavior as measured by the SDQ.
Conclusions: Results indicate promise for the effectiveness of the Fun FRIENDS program as an early intervention program based on the promotion of resilience for Mexican children.

Possible Selves, Motivation, and Classroom Practices: A Qualitative Enquiry with English Teachers in Dhaka, Bangladesh
Authors: Debnath Beauty 
Published: February 2021

Studies around the world show that students’ motivation for learning English as a foreign language is usually interconnected with teachers’ motivation. To explore this relationship, this study investigated five Bangladeshi EFL teachers’ early language learning experiences, their visions of possible L2 selves, their motivations for becoming English teachers and the way they connect their visions with their classroom teaching for motivating students. This study employed L2 Motivational Self System (Dorney, 2005, 2009) as the theoretical framework. It was situated in the constructivist paradigm using a qualitative approach taking the form of a narrative enquiry. Data was collected from teachers’ language biographies and in-depth interviews. The thematic analysis of data revealed teachers’ considerable academic and socio-cultural challenges, their improved motivational states and visions of either ‘Ideal L2 Self’ or ‘L2 Learning Experiences’. Teachers with ‘Ideal L2 Selves’ were found more aware of generating students’ L2 vision. The study also found a considerable influence of social, economic, psychological, infrastructural, and cultural factors on teachers’ professional motivation and commitment. Therefore, the study has brought implications for addressing these factors at an institutional and political level to bring about attitudinal change towards teaching as a profession in Bangladesh.
