Green Preservation of Goatskin to Deplete Chloride from Tannery Wastewater
Authors: Hashem Md. Abul , Payel Sofia , Hasan Mehedi , Momen Md. Abdul , Sahen Md. Sahariar 
Published: May 2021

Globally, in wet-salting preservation, common salt (sodium chloride, NaCl) is generally practiced for the raw animal skin which emits a huge amount of chloride-containing wastewater affecting groundwater quality, human and plant life. Chlorides in tannery wastewater encourage salt-free or less-salt preservation methods of raw skin. In this study, an alternative salt-free ‘green method’ has been described for goatskin preservation with rapidly growing obnoxious weeds Sphagneticola trilobata leaf. The ‘green leaf paste’ was applied on the flesh side of the raw goatskin and compared with conventional wet-salting (50% NaCl) method for 28 days. Different parameters of both sample like moisture, nitrogen, hydrothermal stability, and bacterial growth were periodically assessed and compared. Shoe upper leather was produced from both preserved goatskins. After comparing with standards, the physical properties like tensile strength, elongation at break, bursting strength satisfied the standard requirements. SEM images showed no deterioration to the fiber structure of both samples. Moreover, the suggested method reduces the pollution loads: chloride, total dissolved solids, biochemical oxygen demand, and chemical oxygen demand by 98.04%, 92.9%, 90.2%, and 85.5%, respectively. The overall assessment recommends that the salt-free ‘green method’ utilizing S. trilobata leaf paste could be an attractive system over the conventional wet-salting method.

Study of Effect of Size on Iron Nanoparticle by Molecular Dynamics Simulation
Authors: Kien Pham Huu , Khamphone Yiachu , Trang Giap Thi Thuy 
Published: May 2021

We use the molecular dynamics simulation to study iron nanoparticles (NPs) consisting of 4000, 5000, 6000 atoms at temperatures of 300 and 900 K. The crystallization and microstructure were analyzed through the pair radial distribution function (PRDF), the potential energy per atom, the distribution of atom types and dynamical local structure parameters <fx>, where x is the bcc, ico or 14. The simulation indicated that amorphous NP contains a large number of ico-type atoms that play a role in preventing the crystallization. Amorphous NP is crystallized through transformations of f14 > 0 and fbcc = 0 type to bcc-type atoms when it is annealed at 900 K upon 40 ns. The growth of crystal clusters happens parallel with changing its microstructure. The behavior of the crystal cluster resembles the nucleation process described by classical nucleation theory. Furthermore, we found that the amorphous NP has two parts: the core has the structure similar to the one of amorphous bulk, in while the surface structure is more porous amorphous. Unlike amorphous NP, the crystalline NP also has three parts: the core is the bcc, the next part the distorted bcc and the surface is amorphous. Amorphous and crystalline NPs have part core which has the structure not depend on size. Doi: 10.28991/HIJ-2021-02-03-01 Full Text: PDF
The Performance of the Agri-food Sector in the Recent Economic Crisis and during Covid-19 Pandemic
Authors: Mizik Tamás 
Published: May 2021

Crises impact every sector of the economy; however, the magnitude of that impact varies between the different sectors. The agri-food sector-related lessons learned from the last two crises (global financial crisis in 2008, and the sanctions against Russia in 2014) are that international trade becomes lower and commodity prices rise. This article analyzes the performance of the Hungarian agri-food sector during the last three crises based on international and Hungarian datasets. The results show that impacts depend on many factors, such as the type of the agri-food products (raw material vs. processed product, perishable vs. non-perishable goods, etc.) or the depth of trade integration. It should be noted that Hungary is heavily integrated into the EU’s common market, its major trade partners are the other member states. At the commodity level, the share of raw materials is higher on the export side (e.g. cereals) compared to the import side (e.g. meat products). Based on the results, the impacts of the COVID-19 pandemic were different from the two previous crises. Despite the difficulties in transport, Hungarian exportation expanded and resulted in an increasing trade surplus, while international commodity prices remained stable. The identification of the different impacts of the coronavirus compared to the other two crises is the major finding of the article. Doi: 10.28991/HIJ-2021-02-03-02 Full Text: PDF

Published: May 2021

Background Migration of Venezuelan citizens to other South American countries has increased in recent years. While the prevalence, morbidity, and mortality of infectious diseases in Venezuelan migrants across South America appears to be well described, the non-communicable disease (NCD) and maternal and child health needs in this population is less clear. A scoping review of existing peer-reviewed primary research and grey literature describing the epidemiology of NCDs and maternal and child health needs in Venezuelan migrants in major South American host countries was performed in order to highlight important gaps in knowledge. Methods A scoping review was performed of peer-reviewed research and grey literature for NCD and maternal and child health needs among Venezuelan migrants living in the following host South American countries with greater than 100,000 migrants: Argentina, Brazil, Chile, Colombia, Ecuador, and Peru. A total of 47 electronic databases were searched for primary research published between 2017 and 2020 in either English or Spanish. Results Out of 1,098 initial articles retrieved, 17 records met inclusion criteria, with the majority identified from the grey literature. Most studies were published in 2019 and most were either primary reports published by non-governmental organizations within the grey literature search or cross-sectional qualitative studies. Studies came from Argentina, Chile, Colombia, and Peru, with three records offering a regional perspective. Most studies provided broad data on NCDs and maternal and child health needs but lacked granular statistics. Our analysis found the rate of chronic disease among Venezuelan migrants to range from 9-14% within countries who reported this data. Significant rates of psychiatric conditions such as depression and post-traumatic stress disorder were reported. Other conditions described were ophthalmologic diseases, diabetes, chronic pain, asthma, cough, dyslipidemia, hypertension, arthritis, malnutrition, and obstetric complications, although exact statistics were limited. Obstacles to care included lack of healthcare access and affordability. Conclusions Existing reports discuss important needs related to NCDs and maternal and child health in Venezuelan migrants in South American countries, but there are significant gaps in knowledge. Further research must describe in greater detail the prevalence, morbidity, and mortality of NCDs and maternal and child health needs in Venezuelan migrants in this region in order to assist local governments and international humanitarian organizations with providing strategic and unified responses.

<p align="center"><strong>ABSTRACT</strong></p><p><strong><em> </em></strong></p><p> This study aims to find out the effectiveness of Group Investigation method in improving students’ reading ability. This quasi-experimental research design was involved 64 students of SMAN 24 Bandung as the participants. This study used a type of data collection technique including pre test and post test. The conceptual framework for the study included the independent variable of teaching method, and dependent variable of students’ ability in reading. The experimental study was conducted within this framework by using non parametric test. The results of data analysis show that Group Investigation could facilitate the students in improving their reading ability. It can be seen from the result of mean rank and Mann-Whitney U. Furthermore, the results of the pre test and post test indicate that students’ reading ability improved in four indicators, encompassing identifying the explicit information, identifying the main idea of the text, identifying the purpose of the text, and identifying the implicit information of the text. Meanwhile, the results of test in control group indicate that the students’ reading ability improved in two indicators, encompassing identifying the purpose of the text and identifying the synonym of the words. Due to the limitations of the study, it is recommended for other researchers to introduce Group Investigation gradually into the classroom and practice it before the class undertakes a full-scale investigation project and to observe the students’ social interaction skill in the classroom. It is also recommended for every teacher who wants to use this method to fully competent at implementing this method. Despite the need for the further research, this method can be used as a method in teaching reading to EFL learners.</p><p><strong>Keywords:</strong><em> reading ability, Group Investigation. </em></p>

Authors: Alam Syamsu 
Published: May 2021

This study aims to trace the absorption of overhead costs in the production process at Sabbena Soppeng's silk house, to identify appropriate cost drivers in allocating overhead costs to products that are accurate and do not occur distortion.
This research uses descriptive method. Collecting data through interviews, observation, documentation. The analysis was carried out by applying a two-stage activity-based costing model. First, trace overhad costs to the “cost pool”. Second, trace the overhead costs to the product using multiple cost drivers.
The results showed: a) the product category " Kain Sutera" shows a smaller difference of Rp. 3,253.62; b) product category "Sarung sutra ST-0 Standar" shows a bigger difference of Rp 10,997.4; c) product category "Sarung sutera ST-1 Standar" shows a bigger difference of Rp 22,420.49; d) product category "Sarung sutera ST- Sedang" shows a bigger difference of Rp. 28,352.51; e) product category “Sarung Sutera ST-ASL” shows a bigger difference of Rp. 278,342.75. The difference is due to the fact that the traditional overhead system does not use several cost drivers. Meanwhile, the ABC system uses a multi cost driver in charging BOP. So that with the ABC System it is considered that the BOP allocation is more accurate.

Variation in spirometry parameters in children with and without recurrent respiratory problems
Authors: Gauchan Eva , BK Ganesh , Koirala Deepak Prasad 
Published: May 2021

Background: Children having recurrent episodes of respiratory symptoms account for a major source of hospitalization. These children have increased morbidities and if not identified in time can have impaired lung function as adults.
Objectives: The aim of our study was to compare the spirometry parameters and bronchodilator reversibility in children with and without recurrent respiratory problems.
Methodology: This was a prospective observational study conducted in the Pediatric department of Manipal Teaching Hospital comparing 35 children with recurrent respiratory problems and 35 children with no history of recurrent respiratory problems. After thorough instructions, baseline spirometry was done in all children and recordings were noted. Thereafter they were given two puffs of salbutamol (100 µg) and repeat testing was done 20 minutes later. Bronchodilator reversibility was calculated according to standard formula. Various statistical tests were used to compare the findings between the two groups.
Results: The recurrent respiratory problem group had 31 (88%) cases of bronchial asthma, two (5.7%) bronchiolitis obliterans, one (2.8%) pulmonary eosinophilia, and one (2.8%) common variable immunodeficiency syndrome. The median values of FEV1 (p=<0.001), FVC (p=0.007), FEV1/FVC (p=0.005), PEF (p=0.042) and FEF25-75(p=0.026) were lower in the group with recurrent respiratory problems. Post-bronchodilator reversibility of FEV1 (p=0.001), FVC (p=<0.001) and FEF25-75 (p=0.026) was higher in the groups with recurrent respiratory problems
Conclusion: We found that lung function parameters in children with recurrent respiratory problems show features of obstructive defect. The post-bronchodilator response is higher in the group with recurrent respiratory problems as compared to normal children.

Authors: Kafle Rita , Kadel Anuj Raj 
Published: May 2021

Background: Dyslipidemia, a well-known major risk factor for coronary heart disease, is commonly associated with macro-vascular complications in patients with diabetes mellitus. Increased level of triglycerides and reduced levels of HDL cholesterol are common lipid abnormalities in diabetes.
Objectives: The aim of the study was to study the prevalence and pattern of lipid abnormalities among diabetic patients attending general practice outpatient department in Kathmandu Medical College Teaching Hospital.
Methodology: This is a descriptive cross-sectional study conducted in the Department of General Practice and Emergency of Kathmandu Medical College Teaching Hospital, Duwakot, Bhaktapur. Convenience sampling technique was used.After obtaining informed consent, 120 diabetic patients from January 2020 to March 2020 were included. The data collected was entered in the Statistical Package for the Social Sciences software and analyzed. Ethical clearance was taken from the Institutional Review Committee of Kathmandu Medical College.

Results:The average TC, HDL, TG and LDL level among the female participants were 186.18 mg/dl, 41.91 mg/dl, 194.63 mg/dl, 111.88 mg/dl respectively and 186.30 mg/dl, 38.80 mg/dl, 205.60 mg/dl, 125.80 mg/dl among the male participants respectively.Eighty-five (71%) patients had a low HDL level. Total cholesterol was found to be high in 38(32%) participants. LDL cholesterol was high in 77(64%) participants. The triglyceride level was high in 85(71%) participants.
Conclusion: This study showed that some diabetic individuals have a lipid abnormality while others did not. This shines light on the importance of regular testing for lipid profile in diabetic individuals because we cannot reasonably predict when a patient will develop dyslipidemia.
