Statistical regularities cause attentional suppression with target-matching distractors
Authors: Kerzel Dirk , Huynh Cong Stanislas
Published: November 2020

Visual search may be disrupted by the presentation of salient, but irrelevant stimuli. To reduce the impact of salient distractors, attention may suppress their processing below baseline level. While there are many studies on the attentional suppression of distractors with features distinct from the target (e.g., a color distractor with a shape target), there is little and inconsistent evidence for attentional suppression with distractors sharing the target feature. In this study, distractor and target were temporally separated in a cue–target paradigm, where the cue was shown briefly before the target display. With target-matching cues, RTs were shorter when the cue appeared at the target location (valid cues) compared with when it appeared at a nontarget location (invalid cues). To induce attentional suppression, we presented the cue more frequently at one out of four possible target positions. We found that invalid cues appearing at the high-frequency cue position produced less interference than invalid cues appearing at a low-frequency cue position. Crucially, target processing was also impaired at the high-frequency cue position, providing strong evidence for attentional suppression of the cued location. Overall, attentional suppression of the frequent distractor location could be established through feature-based attention, suggesting that feature-based attention may guide attentional suppression just as it guides attentional enhancement.
Analisis Pengendalian Internal Piutang Usaha Dalam Meminimalisir Piutang Tidak Tertagih

Published: November 2020

Credit sales are carried out by companies to attract many customers, so that the sales volume  can increase compared to sales in cash. However, credit sales have several risks including uncollectible receivables. Hence, internal control of receivables is very important as receivables, in the future, must be recorded in cash flow. If there are customers who are overdue in payments or fail to  settle their debts due to various reasons, the company’s operational activities will be disrupted.

          The purpose of this study is to determine the internal control of trade receivables in minimizing uncollectible receivables in a company.

          PT Bostinco is a manufacturing company that produces safes, filling cabinets, roll-o-pack sliding cabinets, fire doors, etc. In its regular sales practice, the company  uses a credit sales system,  preceded by  down payment requirements based on  the agreement between the seller and the customers. As credit sales made by the company will cause trade receivables,  internal control is carried out to minimize the risk of uncollectible receivables.

          The results of the study show that internal control of accounts receivable in minimizing uncollectible receivables runs poorly due to the findings of  the original Delivery Order files that are still  discharged. Moreover, the company has some VAT debt arrears which  prevents it from getting the tax invoice number. Unfortunately, there is no penalty agreement for  late payment despite of quite large amount of receivables.

In 2020 companies in Indonesia have to implement PSAK 71 to replace PSAK 55. With the forward looking Expected Credit Loss approach in PSAK 71, profit of the banking industry has the potential to be declining because banks have to prepare Allowance for Impairment Losses since the initial recognition of financial assets. This study aims to find out  the application of PSAK 71 in the presentation of allowance for impairment losses on banking companies in Indonesia and examine its financial performance using the CAMEL method. This research was conducted at CTBC Bank of Indonesia

          The type of data used in this study is secondary data which was obtained in the form of annual reports containing audit reports and other additional information. The analysis of the data is intended to find out whether the presentation of allowance for impairment losses at CTBC Bank is in accordance with PSAK 71 or not,  and analyze the company’s financial performance

The results of this study show that CTBC Bank of Indonesia has implemented PSAK 71 of allowance for impairment losses properly and the recalculation of impairment losses was in accordance with transitional provisions of PSAK 71 in 2017. This  reduced the value of Bank’s CAMEL by 3,33 resulting from the decrease of net income and total assets. However, as of December 31, 2018 the company has succeeded in raising the CAMEL value to 85,55 and achieved a rating of healthy status from Bank Indonesia

Authors: Krismonika Mahasani Puspitarani , Tartilla Nilda
Published: November 2020

Companies are currently involved in various forms of tax planning to reduce the estimated tax liability. On the other hand, aggressive tax actions are bad for the companies because it requires them  to report lower profits.  Frank et al (2009) found there was a tendency that companies were able to report greater profits and have a low tax burden simultaneously. Thus,  it can be said that trade-offs don't always occur. This study aims to assess the influence of the aggressiveness of financial reporting on tax aggressiveness in manufacturing companies from 2015-2018 by using the mechanism of Good Corporate Governance as a moderating variable.  

The data used in this study are secondary data obtained from the financial statements and annual reports of manufacturing companies from the Indonesia Stock Exchange. The population of this research is 27 manufacturing companies listed on the Indonesia Stock Exchange. Selection of the sample was done using the purposive sampling method. The analytical method used in this research is multiple regression or multiple regression with the SPSS version 25 computer program.  Hypothesis test was performed using multiple regression methods and MRA (Moderated Regression Analysis).

            The results of this study indicate that the aggressiveness of financial reporting on manufacturing companies simultaneously has a significant positive effect on tax aggressiveness with a significance value of 0.003. The mechanism of Good Corporate Governance with indicators of Institutional Ownership and Managerial Ownership simultaneously has a significant negative effect on tax aggressiveness with a significance value of 0.001 and 0.007. As well as the mechanism of Good Corporate Governance, it is stated that it can weaken the effect of the aggressiveness of financial reporting on tax aggressiveness.

Published: November 2020

The purpose of this study was to investigate the magnetohydrodynamic (MHD) mixed convection flow and heat transfer of a dual stratified micropolar fluid over a vertical permeable stretching/ shrinking sheet with chemical reaction and heat source. The governing nonlinear partial differential equations are reduced into a system of nonlinear ordinary differential equations using an appropriate similarity transformation. Then, the obtained ordinary differential equations are solved numerically using the boundary value problem solver (bvp4c) in MATLAB software. The numerical results are tabulated and plotted for the heat transfer characteristics, namely, the skin friction coefficient, the local Nusselt number, the local Sherwood number as well as the velocity, temperature and concentration profiles for some values of the governing parameters. The present numerical results also have been compared with the previous reported results for a particular case and the comparisons are found to be in an excellent agreement. The results indicate that the skin friction coefficient and the local Nusselt number increase with chemical reaction and heat source. The magnitude of the local Sherwood number increases with the increasing of chemical reaction parameter. However, the magnitude of the local Sherwood number decreases with heat source effect.

In the presence of slips, non-uniform heat source/sink, thermal radiation and magnetohydrodynamic (MHD), micropolar hybrid nanofluid and heat transfer over a stretching sheet has been studied. The problem is modelled as a mathematical formulation that involves a system of the partial differential equation. The similarity approach is adopted, and self-similar ordinary differential equations are obtained and then those are solved numerically using the shooting method. The flow field is affected by the presence of physical parameters such as micropolar parameter, magnetic field parameter, suction parameter and slip parameter whereas the temperature field is affected by thermal radiation parameter, space-dependent parameter, temperature-dependent internal heat generation/absorption parameter, Prantl number and Biot number. The skin friction coefficient, couple stress and local Nusselt number are tabulated and analysed. The effects of the governing parameters on the velocity profiles, angular velocity profiles and temperature profiles are illustrated graphically. The results of velocity profiles, angular velocity profiles and temperature profiles are also obtained for several values of each parameters involved.

Published: November 2020

In order to imitate the atherosclerosis artery disease and determine the key issues, Computational Fluid Dynamics (CFD) is able to play a leading rule in the analysis of flow physics within the clogged arteries, in particular the stenosis artery. The problem of blood flow blockage through the blood vessel has been investigated numerically within a stenosis artery. In this work, a CFD technique was employed to solve the three-dimensional, steady, laminar and non-Newtonian Carreau model blood flow through a stenosis artery using Star-CCM+ software. The shape of stenosis that has been selected is a trapezoidal with two cases (70% and 90% blockage). Shear rate, streamlines, vorticity and importance factor are examined to assess the influence of non-Newtonian model through the test section, the Carreau model was compared with Newtonian model. The clinical significance of the shear rate is reported for the examined cases, observing that the levels of non-Newtonian model are predicted to be higher in the 90% blockage than that observed within the 70%; the same finding as related with the axial velocity and vorticity. The levels of re-circulation areas and vorticity are showed to be enlarged in the Carreau model compared with the case of Newtonian.

Published: November 2020

Prior to the current pandemic, Nigeria has witnessed the emergence of other viruses which were contained. Science is yet to proffer complete solution to this new wave of virus known as Covid-19, and the magnitude on other aspects of life is far reaching. Despite negative predictions and a wobbling health sector, the number of casualties due to the pandemic has been relatively low. Researchers are researching to find a vaccine to the virus which has culminated in the death of thousands all over the world. This study attempts to examine issues related to leadership, politics and economic policy within the context of the pandemic. The paper argues that one major problem Nigeria grapples with is leadership deficit which inevitably has affected our disposition and response to emergencies. The aforementioned can be adduced to failure of leadership to invest heavily in the health sector over the years, which is the sole responsibility of government. The study also examined the politics involved in the Covid-19 and how the economy has been affected thus far. It stressed the need for leaders to prioritize transparency and accountability while there should be a clear demarcation between politics and reality. It also buttresses the need for speedy economic reforms.

‘Mirror, Mirror On the Wall, Who’s the Better of Them All?’Fashion Magazines: A Social Tool of Empowerment or Enslavement?
Authors:   Associate Professor, Department of Media Studies, CHRIST (Deemed to be University), Naresh Suparna
Published: November 2020

The concept of ‘fashion’ and ‘fashionableness’ is a highly contested one with differing opinion as to what constitutes either, with no clear-cut move made to clarify the correctness of the myriad understanding behind the term. People who are seemingly fashionable or are considered fashionable by members of the community exert pressure on others--a pressure to follow, pressure to keep up or pressure to agree to the standards set by the supposedly fashionable as the bar for things fashionable. In recent times public discourse has looked at the immense pressure fashion has exerted on women in any given society. Be it things as banal as clothes and cosmetics or complex issues such as political ideologies espoused by one; everything in contemporary times is weighed by the fashionably endowed. Many wear their fashion sense as a badge of pride and achievement, much to the discomfort and dismay of those who think and behave otherwise; and no more is this awkwardness as obvious as it is amongst women. Media platforms add to the general sense of the divide among women in society by taking a decided stance in favour of the fashionable women, increasing the angst and anxiety of those women who aren’t. Do fashion magazines add to women’s confusion when it comes to issues of fashion or do fashion magazines help in allaying their fears? Some of these issues will be explored in the present paper.

This study examined leadership and non-financial performance at the brewery industry in Nigeria. The study used cross-sectional survey research design to survey 736 senior and junior employees of the company. The Multifactor Leadership Questionnaire, job satisfaction scale, three-component commitment scale, and turnover intention scale was adopted to collect data. The participants were recruited through Survey Monkey. Stratified sampling was adopted to ensure representative sample. Three hypotheses were tested using Pearson’s correlation and hierarchical regression analysis. Findings of the study revealed that the three leadership styles are positively correlated with job satisfaction, and employee commitment. Also the three leadership style are negatively and statistical correlated with turnover intention. Cadre of employee (senior or junior employee) is a significant predictor of employee job satisfaction and commitment. Both age and years of experience on the job are significant predictor of employee turnover intention. On the basis of the aforementioned findings, this study concluded that the adoption of effective leadership style is critical to job satisfaction, employee commitment and turnover intention. It is recommended that leaders should adopt effective leadership style to foster employee job satisfaction and commitment with a view of lessen turnover intention.

Outdoor natural environments are well proven to have psychological, physical, and social benefits, particularly those attached to healthcare facilities. Despite that, the Egyptian Codes devoid of data related to the design of such gardens, which hinders the design process and the inclusion of these spaces within health care facilities. Thus, this paper seeks to reach a set of considerations for the design of different types of therapeutic gardens by summarizing the findings and recommendations of some evidence-based design (EBD) research and post-occupancy evaluations (POEs). Post-occupancy evaluations lack to determining the percentage of achieving the design principles in the garden. Therefore, in addition to the behavioral and visual observations to evaluate Children's Cancer Hospital garden in Egypt (CCHE), an audit tool was integrated to combine the advantages of audit tools and POEs. With this merging, we can reach a steady form of post-occupancy evaluations of pediatric cancer hospital’s gardens to be a guide for future researches and landscape architects.

Published: November 2020

The traditional method of teaching approach in Indian schools is basically a threat for flexible learning where students are given importance based on their learning preferences. Students are not encouraged for maximized learning through their different learning style when teachers in classroom use the only chalk-talk method of teaching approach. The main objective of this study is to identify the learning essentials of the adolescents, which helps the teachers to create positive interest among students in learning &classroom behaviour and improve their comprehension in day to day learning. In Indian schools some are auditory learners, some visual and some are kinaesthetic learners, but majority of the students learn better throughmulti-dimensional teaching approach which includes Audio, Visual and Kinaesthetic teaching approach. But due to the use of the traditional method of teaching in Indian schools the students are unable to perform better in their academics. The family, peer group as well as the school environment is also causing several emotional and psychological problems among these adolescents which is also a cause behind their learning interest.Hereby, we can come to the conclusion that the students are deferent in learning. But there is a severe need to identify the learning essentials of adolescents to explore the new model in classroom teaching to encourage them towards learning and maximize their academic performance.Secondary data method is used and the study is descriptive in nature.

The final compounds were tested for antibacterial activity against Gram-positive bacteria: Staphylococcus aureus MTCC 3160, Bacillus subtilis MTCC 441; Gram-negative bacteria: Escherichia coli MTCC 443, and, for antifungal activity, against Candida albicans MTCC 227 and Aspergillus niger MTCC 281, taking ciprofloxacin as antibacterial and fluconazole as antifungal standard drugs. Compound 7a6 was found to be the most effective antibacterial (MIC = 3.12 µg/ml), and compounds 7a2 and 7d1 (MIC = 3.12 and 6.25 µg/ml) had the most effective antifungal effects on the selected strains, as compared to the standard drugs. The results of antioxidant studies revealed that compound 7b1 was found to be most active antioxidant, with 40.4±0.687 µg/ml, and compounds 7b3, 7d7, and 7d4 also showed promising free radical scavenging activity, as compared with the standard drug ascorbic acid.
Scheduling Dynamic Parallel Loop Workflow in Cloud Environment
Authors: SMANCHAT Sucha , VIRIYAPANT Kanchana
Published: November 2020

Scientific workflows have been employed to automate large scale scientific experiments by leveraging computational power provided on-demand by cloud computing platforms. Among these workflows, a parallel loop workflow is used for studying the effects of different input values of a scientific experiment. Because of its independent loop characteristic, a parallel loop workflow can be dynamically executed as parallel workflow instances to accelerate the execution. Such execution negates workflow traversal used in existing works to calculate execution time and cost during scheduling in order to maintain time and cost constraints. In this paper, we propose a novel scheduling technique that is able to handle dynamic parallel loop workflow execution through a new method for evaluating execution progress together with a workflow instance arrival control and a cloud resource adjustment mechanism. The proposed technique, which aims at maintaining a workflow deadline while reducing cost, is tested using 3 existing task scheduling heuristics as its task mapping strategies. The simulation results show that the proposed technique is practical and performs better when the time constraint is more relaxed. It also prefers task scheduling heuristics that allow for a more accurate progress evaluation.

Published: November 2020

One of the most popular learning and memory tests is the Morris water maze. The Morris water maze is a circular pool filled with water with a hidden platform under the water surface. The test is appropriate for rodents, especially rats and mice. The testing protocol comprises 2 parts that evaluate learning ability and memory retention. When animals are placed in the pool, they experience stress, which is the driving force for discovery of a strategy to leave the water. In the experiment, animals use environmental cues to find the location of the hidden platform in the pool. After consecutive training days, animals can more quickly locate the hidden platform. The last day of the task involves a memory test without the platform. It shows a limitation of the test in mild learning and memory deficit models such as 2-vessel occlusion. Differences between the normal and memory impairment models are expressed only in a narrow range. So, we tried to modify the original protocol for mild learning and memory impairment models. We used an albino rat strain for the experiment. A pre-training strategy of 3 days of swimming in the pool with a visible platform prior to the ordinary task was used. The results suggest that this pre-training strategy improved learning and memory in the rat model. When compared to normal rats and 2-vessel occlusion rats (a rat model for vascular dementia), those that participated in the pre-training strategy showed an increase in the percent difference of area under the curve for learning trials. In conclusion, the pre-training strategy increases ability to discriminate learning and memory impairment in the rat model, especially for the mild learning and memory deficit models.

Authors: SUGIYANTO Gito
Published: November 2020

Traffic congestion is one of the significant transport problems in many cities in developing countries. Increased economic growth and motorization have created more traffic congestion. The application of transportation demand management like congestion pricing can reduce congestion, pollution and increase road safety. The aim of this research is to estimate the congestion pricing of motorcycles and the effect of a congestion pricing scheme on the generalized cost and speed of a motorcycle. The amount of congestion pricing is the difference between actual generalized cost in traffic jams and in free-flow speed conditions. The analysis approach using 3 components of generalized costs of motorcycle: vehicle operating, travel time and externality cost (pollution cost). The approach to analyze the pollution cost is marginal-health cost and fuel consumption in traffic jams and free-flow speed conditions. The value of time based on Gross Regional Domestic Product per capita in Yogyakarta City in October 2012. The simulation to estimate the effect of congestion pricing using Equilibre Multimodal, Multimodal Equilibrium-2 (EMME-2) software. The results of this study show that while the free-flow speed of a motorcycle to the city of Yogyakarta is 42.42 km/h, with corresponding generalized cost of IDR1098 per trip, the actual speed in traffic jams is 10.77 km/h producing a generalized cost of IDR2767 per trip, giving a congestion pricing for a motorcycle of IDR1669 per trip. Based on the simulation by using EMME-2, the effect of congestion pricing will increase on vehicle speed by 0.72 to 8.11 %. The highest increase of vehicle speed occurred in Malioboro Street at 2.26 km/h, while the largest decrease occurred in Mayor Suryotomo Street at north-south direction at 1.07 km/h. Another effect of this application for motorcycles users will decrease the generalized cost by 1.09 to 6.63 %.

Factor IX (FIX) is an important protein in the blood clotting cascade, playing a key role. Previously, an anti-FIX RNA aptamer (34 mer) was generated to block blood coagulation, in order for it to be used as a substitute for currently available anti-coagulants. Bases in the loop region of this RNA aptamer have mainly involved the binding of FIX. Changes in 2 bases were found to diminish the complex formation with FIX, which could be predicted by evaluating the alteration in the secondary structure of the aptamer. In this study, computational analyses were carried out on the secondary structure analysis with aptamer, and the possible changes observed. It was confirmed that both A10 and A12 are the key bases involved in the complex formation with FIX. Similar structural analysis may helpful in identifying and predicting the importance of RNA bases in maintaining the secondary structure and their binding affinity.

This study investigated the nucleophilic substitution reaction mechanisms of 5 oxatriquinane derivatives, namely: oxatriquinane (OTQ), 1,4,7-trimethyloxatriquinane (TMO), 1,4,7-triethyloxatriquinane (TEO), 1,4,7-tri-iso-propyloxatriquinane (TIO) and 1,4,7-tri-tert-butyloxatriquinane (TTO). In addition to the G3 conformation (one with the substituent groups at 1,4 and 7 positions pointing into the plane of the paper) originally proposed by the previous workers, Mascal et al. in 2008 and Gunbas et al. in 2013, one more geometrical isomer was considered again for each of the derivatives, the 2G1 isomer (one in which only 2 of the 3 substituent groups at 1,4 and 7 positions are into the paper plane). Geometry optimization and determination of transition state properties of the conformers corresponding to each molecule (in the presence of azide ion, N3-) provided theoretical evidences on the possible reaction mechanisms. The 2G1 conformer for TTO was found to be unstable. The reactions of OTQ, TMO and TEO with azide ion (N3-) followed SN2 pathway, with SN1mechanism completely lacking. This finding is in agreement with the first set of reports published on this subject in 2008 and 2010 by Mascal’s group. For TIO (in the presence of azide ion), only the presence of SN1 mechanism could be proved without any observation of transition state (TS), even though, it possesses a 2G1 conformer. TTO surprisingly, showed marked evidence of SN1 mechanism also without any evidence of TS. The results obtained showed that OTQ derivatives up to TEO undergo nucleophilic substitution predominantly via SN2, and above which (i.e. for TIO and TTO) the mechanisms predominantly become SN1.

This research aims to study the spatial characteristics of drought throughout the year in Kuan Kreng Peat Swamp (KKPS) by using various drought indices. Meteorological drought indices were analysed by using data of precipitation during the period of the study 1984 - 2013. The standardized precipitation index (SPI) was calculated on the basis of precipitation deficit. Vegetation-based drought indices were also derived from the analysis of Landsat satellite images based on the normalized difference drought index (NDDI). In addition, hydrological drought indices were studied based on the water table level (WTL) and drought assessments were also based on the standardized water level index (SWI) calculated from data on surface water and the groundwater level in the peat swamp forest. The results are presented in the form of maps of geographic information system (GIS) based on the SPI, NDDI, WTL and SWI. The study focused on the droughts in 2 years: 2010 and 2012. The year 2010 was subject to the El Niño phenomenon while 2012 was not. However, peat fires occurred in both years. The assessment of drought using the SPI, WTL and SWI reveals that drought occurred from April to October due to there being less rainfall during that period. The NDDI reveals that vegetation was affected by the drought between February and September due to this being the summer season with high temperatures and less moisture in the air. The 3 types of drought indices used, meteorological, vegetation and hydrological for the period of April to September indicate the likelihood of peat fires in the KKPS area during that period. The results of this study contribute to the understanding of how spatial and temporal data can be used to predict and measure the severity of drought, to which the study area is vulnerable and to the concomitant risk of peat fires.

The emergence of Twitter in Thailand has given millions of users a platform to express and share their opinions about products and services, among other subjects, and so Twitter is considered to be a rich source of information for companies to understand their customers by extracting and analyzing sentiment from Tweets. This offers companies a fast and effective way to monitor public opinions on their brands, products, services, etc. However, sentiment analysis performed on Thai Tweets has challenges brought about by language-related issues, such as the difference in writing systems between Thai and English, short-length messages, slang words, and word usage variation. This research paper focuses on Tweet classification and on solving data sparsity issues. We propose a mixed method of supervised learning techniques and lexicon-based techniques to filter Thai opinions and to then classify them into positive, negative, or neutral sentiments. The proposed method includes a number of pre-processing steps before the text is fed to the classifier. Experimental results showed that the proposed method overcame previous limitations from other studies and was very effective in most cases. The average accuracy was 84.80 %, with 82.42 % precision, 83.88 % recall, and 82.97 % F-measure.

In this paper, toluene removal via photocatalytic oxidation using TiO2 dip coated nanofilms is presented. Nanofilms were synthesized from bacterial cellulose using the electrospinning technique. The physical properties of the nanofilms were analyzed by scanning electron microscopy (SEM). The ratio of bacterial cellulose/nylon used in the spinning process was 0.165:1. The results from SEM showed that the structure of the TiO2 composite nanofilms was rutile crystalline with an average particle size of 20 nm, and synthesized nanofilms had an average size of 20 - 30 nm. The band gap energies of TiO2-dip coated nanofilms ranged from 3.18 - 3.21 eV. SEM results of TiO2 coated nanofilms suggested that the TiO2 was rather uniformly distributed onto the surface of the nanofilms. The actual amount of TiO2 coated on the nanofilms was estimated using thermogravimetric analysis (TGA) for 1x1 cm2 surface area. It was found that 0.1852, 0.2897 and 0.7275 mg of TiO2 were coated on the surface of the nanofilms for 1, 2.5 and 5 % (weight) TiO2 dosage, respectively. The photocatalytic activity of the nanofilms was tested for the removal of gaseous toluene in a photocatalytic reactor. Experimental conditions were set as follows: UV light intensity of approximately 2.7 mW.cm-2, flow rate of 0.2 L.min-1, and an initial toluene concentration of about 200±20 ppm, and a retention time at 200 min. The degradation rate of toluene increased with increasing dosage of TiO2 from 1, 2.5 and 5 %. The nanofilms at a 5 % dosage yielded the highest removal efficiency of 92.71 %, followed by the 2.5 and 1 % dosage, respectively.

Whether multiple single nucleotide polymorphisms (SNPs) of BCL11A and HBS1L-MYB genes affect hemoglobin (Hb)F production and hematological parameter variation in β-thalassemia/HbE and homozygous HbE in Thai subjects with low and high HbF levels are still unclear. Three SNPs of BCL11A gene (rs1427407, rs10189857 and rs11886868) and 3 SNPs of HBS1L-MYB gene (rs4895441, rs9399137 and rs28384513) were analyzed in 45 β-thalassemia/HbE patients who had HbF levels lower and higher than 15 %, and in 50 homozygous HbE who had HbF levels lower and higher than 5 %. Their hematological parameters were measured using automated blood counter. The HbF level was analyzed using high performance liquid chromatography (HPLC). There were no statistical significant differences of allele and genotype frequencies of 3 SNPs in the BCL11A gene between the groups of β-thalassemia/HbE patients and homozygous HbE subjects with low and high HbF levels. Significant differences in the allele frequencies in HBS1L-MYB SNP rs4895441 (p = 0.041) and rs9399137 (p = 0.048) were observed in homozygous HbE subjects with HbF £ 5 % and > 5 %. Moreover, significant differences in MCV (p = 0.005) and trends towards significant differences in MCH (p = 0.057) and HbF levels (p = 0.051) were found in HBS1L-MYB SNP rs9399137 of homozygous HbE subjects. Therefore, the HBS11L-MYB SNPs especially rs9399137 had an effect on HbF production and the variation of hematological parameters in homozygous HbE subjects, but not in β-thalassemia/HbE patients.
