Published: November 2022

Este trabalho apresenta duas novas metodologias determinísticas para encontrar a máxima capacidade de hospedagem (MCH) de geração distribuída (GD) em sistemas de distribuição. Na abordagem proposta, um problema de otimização é formulado a fim de se calcular o máximo montante de potência a ser acomodado em uma rede elétrica de média tensão sem violar limites operacionais. Para a formulação proposta, as equações do método de injeção de correntes são consideradas como restrições de igualdade para se computar o fluxo de potência ótimo (FPO) proposto. Como restrições de desigualdade, consideram-se os limites máximos e mínimos de magnitudes de tensão, de potências geradas em cada barra e da possibilidade de ocorrência de reversão do fluxo na subestação principal da concessionária. Ainda como contribuição desta pesquisa, propõe-se uma nova metodologia para se determinar a MCH em sistemas multifásicos desequilibrados em que, através de modificações no FPO, almeja-se determinar a máxima quantidade de potência a ser hospedada em redes trifásicas, multiaterradas, a quatro fios. Para isso, restrições de desigualdade incorporam limites associados às magnitudes de tensão em cada fase, fator de desequilíbrio e tensão de neutro. Equações do método de injeção de correntes trifásico a quatro fios são tratadas como restrições de igualdade. O problema de otimização é resolvido via método de pontos interiores. Adicionalmente, a fim de considerar incertezas nos métodos propostos, as cargas do sistema são modeladas através da função de densidade de probabilidade Gaussiana, considerando uma dispersão estatística em relação a seus valores nominais com o objetivo de se avaliar impacto de incertezas nos valores de carga nos valores de MCH. Simulações computacionais são conduzidas utilizando dois sistemas: o equivalente monofásico da rede de distribuição da Universidade Federal de Juiz de Fora, composto de 23 barras e o sistema trifásico desequilibrado de 33 barras do IEEE. Diversas análises são efetuadas considerando as unidades de geração distribuída alocadas de maneira dispersa nas redes a serem avaliadas. Ainda, a fim de validar as metodologias propostas, os resultados são comparados à trabalhos correlatos da literatura, mostrando versatilidade e aplicabilidade das metodologias propostas nesta dissertação.
Utilização e análise de uma sequência didática com metodologias ativas como proposta para o ensino de genética
Authors:   , Cezana Nathália Alcântara Oliveira
Published: November 2022

Na atualidade, a genética ganhou grande notoriedade pela mídia, fazendo com que muitos dos seus termos e conceitos, como DNA e mutação, tornassem presentes no cotidiano de todos os cidadãos independentemente de possuírem ou não conhecimentos científicos. Apesar disso, o ensino tradicional expositivo do conteúdo de genética praticado na maioria das escolas de Ensino Médio não tem se mostrado uma ferramenta eficaz para levar o aluno a uma alfabetização científica plena e a uma contextualização com os assuntos atuais. Diante disso, a utilização de metodologias ativas de ensino pode representar uma importante ferramenta de mudanças desse cenário. O presente estudo foi construído visando desenvolver e analisar uma sequência didática com estratégias ativas de ensino de Genética realizada com alunos de três turmas de 3° ano do Ensino Médio no Colégio Estadual Antônio Carlos Magalhães na cidade de Itabela/BA. Antes e após o desenvolvimento das atividades da sequência didática, os alunos participantes da pesquisa elaboraram mapas conceituais referentes ao tema a fim de verificar o nível de conhecimento acerca dos conceitos básicos de Genética desenvolvidos com a utilização de recursos ativos. Além disso, após cada aula com metodologia ativa, os alunos responderam um questionário de usabilidade referente à atividade realizada. Levando em consideração que a escola, onde foi desenvolvida a pesquisa, funcionava com sistema híbrido de ensino (aulas presenciais e remotas) devido a pandemia da Covid-19, foi necessário a adaptação das atividades. As informações obtidas nos questionários foram analisadas qualitativamente e os dados obtidos nos mapas mentais analisados de forma quantitativa. A partir da análise dos mapas, verificamos que os mapas finais obtiveram notas estatisticamente maiores que as notas dos mapas iniciais (p>0,000001). Assim, concluímos que a utilização de métodos alternativos de ensino pode potencializar a construção do conhecimento em relação aos conceitos básicos relacionados à genética.
Habitar na pandemia: a influência da arquitetura nas condições de bem-estar domiciliar das mulheres idosas
Authors:   , Paula Ana Luiza Delgado de
Published: November 2022

O contexto da pandemia de Covid-19 e o distanciamento social decorrente da mesma trouxeram alterações no modo de viver, modificando as relações dos indivíduos com a moradia, e expondo as deficiências da arquitetura residencial brasileira. No Brasil, paralelamente, a estrutura familiar vem se modificando e demonstrando uma ampliação da população idosa, sendo a maior parte desses idosos do sexo feminino. No cenário atual, faz-se importante entender as percepções e a influência que a casa proporciona para a saúde psicológica das mulheres idosas e para o seu bem-estar. O principal objetivo da pesquisa é compreender, através do que motivou as mulheres idosas a realizarem reformas em suas casas durante o período de pandemia, a percepção dessas mulheres acerca da influência do ambiente construído em seu bem-estar. Visando atender aos objetivos, inicialmente foi realizada uma pesquisa bibliográfica interpretativa, através de uma revisão de literatura que versou sobre os principais conceitos trabalhados na pesquisa; posteriormente, realizou-se a coleta de dados empíricos através de entrevistas on-line com dez idosas que realizaram reformas em suas casas na cidade de Juiz de Fora; por fim, foi feita a apreciação de resultados utilizando o método da análise do discurso. Após a consumação desse estudo, foi possível perceber três principais motivações para a realização das reformas por parte das idosas, sendo elas: mudança na rotina causada pelo distanciamento social; busca por identidade no ambiente construído; e busca por melhorias nas condições de execução das atividades instrumentais de vida diárias (AIVDs). Os resultados obtidos nesta pesquisa demonstraram que, de forma consciente, as mulheres idosas percebem a influência do ambiente construído nas suas condições de bem-estar e de qualidade de vida e reafirma o que já vem sendo exposto em alguns estudos sobre o tema: que os elementos do ambiente construído que são capazes de promover o bem-estar neste público vão além dos temas pertinentes aos confortos ambientais – aspectos luminosos, térmicos, acústicos e tácteis –, comumente tratados nas pesquisas que avaliam o bem-estar na habitação, abrangendo também questões referentes à identidade e à memória.

Historical quarters in cities are a living embodiment of people’s culture and their collective memory, which preserve their heritage and past achievements. Urban identity depends on meeting the current needs while preserving the past. At the same time, urbanization exercise pressure on most countries, therefore they require updating administrative law regulation tools capable of protecting the identity of the rich national heritage. The aim of the article was a comparative legal analysis of the realities and prospects of preservation of historical districts of cities in the context of the practice of administrative law regulation of Ukraine and the Federal Republic of Germany. The methods of comparative legal analysis and observation were the leading methodological tools. The research revealed specific physical, socio-economic, and socio-cultural factors of urbanization, which caused noticeable and significant changes in the features of the administrative law tools that regulate urban planning. It was established that the widespread German concept providing that every planning act of a lower-level body must take into account certain mandatory provisions established by the acts of higher-level bodies is gradually being tested in Ukraine. It is substantiated that the armed aggression of the Russian Federation forces Ukraine to take further actions to build new safe real estate objects and preserving historically significant buildings that were damaged by war. In this context, the national administrative law tools that regulate urban planning in Ukraine will also be transformed. The vector of further scientific research will be a comparison of the practice of implementing administrative law tools that regulate urban planning in terms of post-war reconstruction in the selected states.

RIS-Based Steerable Beamforming Antenna with Near-Field Eigenmode Feeder
Authors: Tiwari Krishan Kumar , Caire Giuseppe
Published: November 2022

We present a novel, power and hardware efficient, antenna system leveraging the eigenmodes of the over-the-air propagation matrix from an active multi-antenna feeder (AMAF) to a large reflective intelligent surface (RIS), both configured as standard linear arrays and placed in the near field of each other. We demonstrate the flexibility of the proposed architecture by showing that it is capable of generating radiation patterns for multiple applications such as very narrow beams with low side lobes for space-division multiple access communications, wide-angle beams for short range automotive sensing and sectorial beaconing, and monopulse patterns for radar angular tracking. A key parameter in our design is the AMAF-RIS distance which must be optimized and it is generally much less than the Rayleigh distance. For a given AMAF aperture, the optimal AMAF-RIS distance increases as a function of the RIS size. The AMAF-RIS loss is compensated almost exactly by the larger aperture gain of the RIS leading to almost constant RIS gain with increasing RIS sizes. This allows to choose different beam angular selectivities with the same center beam gain. Active RF amplification is done at the AMAF only, thus resulting in a much higher power efficiency and much lower hardware complexity than conventional phased arrays with same beamforming performance.

Authors: Koç Emine , Şahin Nevin Hotun
Published: November 2022

Introduction

In pregnant women, the rate of falling is similar to that of women older than 70 years. According to the literature review, there is no risk of falling assessment tool that is specific to pregnancy. The aim of the study was to develop a risk of falling assessment scale for pregnant women.

Methods

This is a methodological study. The study's population consisted of pregnant women who sought follow-up care at a state hospital's maternity ward between November 2016 and November 2017. The study sample included 630 pregnant women who met the inclusion criteria and volunteered for the study. The Pregnant Women Information Form and Assessment Scale for Risk of Falling in Pregnant Women were used as data collection tools.

Results

During the scale development process, an item pool draft of 63 questions was developed and submitted to 10 experts for feedback. The findings of the content validity analysis revealed that the average of the items was 0.95, validity was good, and the number of items on the scale was reduced to 42 according to the experts' suggestions. The Cronbach α coefficient of the scale was found to be 0.604 (moderately reliable). It was discovered that the CART and QUEST algorithms on the scale were successful models for estimating the status of falls in pregnant women.

Conclusion

A 42-item assessment scale for the risk of falling in pregnant women was developed, and it was determined that the scale was a valid and reliable tool.
Comments on media trends in South Africa based on AMPS 1976-1980
Authors: Oosthuizen Thomas
Published: November 2022

In this article, which is based on data obtained from the annual AMPS projects of the SAARF, media trends in South Africa is commented on. It is observed that while the media use among the Coloureds, Whites and Asians is declining (all media except television), blacks show an overall increase in media use. This trend is observed in daily newspaper reading (although there was a slight decrease for blacks in the last year), radio listening, television viewing and cinema attendance, even though it is slight in instances. These trends suggest that reasons have to be determined for the increasing alienation between die media and sectors of the population. In a country where most media are primarily aimed at the whites, these trends also stress the need for media which will serve the interests of blacks.

How the industrial journalist can promote good relations
Authors: Venter Dirk , Olivier Bosman
Published: November 2022

The industrial journalist has a basic responsibility to promote good relationships between employer and employee. Efficient two-way communication through the house journal is of vital interest to the modern company or organisation to ensure mutual understanding goodwill and appreciation. Managements must inform and motivate their employees at all times, drawing them closer to the heart of the company or organisation through messages conveyed by management supporting their job security, remuneration and recognition and increasing their insight and knowledge of the total work environment. Managements should also be susceptible to their fears or desires in the labour context, allowing the employee to express his views and opinions in a responsible, loyal fashion to his fellow-employees and to management. Silence in the work situation no longer implies consent.

Adapting the 3S-model for investigating trust in arc solutions in the Danish construction industry
Authors: Lehoczky Dániel , Garcia Dean , Gade Peter Nørkjær
Published: November 2022

Automated solutions to building compliance checking has been slow in its implementation in the Danish construction industry. Mainly socio-technical barriers, such as trust in automation challenge the spread of technological advances from research and development. This paper studies the trust relationship of Architectural, Engineering, and Construction (AEC) professionals towards Automated Rule Checking (ARC) systems in Denmark. The 3S-model from the field of cognitive psychology was employed to help understanding the varying ways people assess information credibility. Three hypotheses were tested through experimentation to investigate the significance of different information features, and pertaining user characteristics on human-automation trust behaviors in the domain of ARC. Although the highly specified research area targeted a relatively small demographic within the Danish construction industry, the findings present an interesting new perspective on the common characteristics and trust behaviors of the end user. With the refinement of the framework’s application, the 3S-model can elucidate the many factors that are believed to influence technology acceptance within the industry. This research aims to contribute to the development of ARC solutions with a front-end viewpoint on trustworthiness.
Hybrid feature selection framework for predicting bridge deck conditions
Authors: Omar Abdelhady , Moselhi Osama
Published: November 2022

Bridge decks’ maintenance funding requirements are influenced by bridge decks' current and predicted future conditions. Additionally, the serviceability of bridges may be negatively impacted by the degradation of bridge decks. Bridge inspections require considerable effort, time, cost, and resources; besides, such inspections may introduce hazards and safety concerns. This paper introduces a data-driven hybrid feature selection framework for predicting bridge deck deterioration conditions and applying it to a bridge deck in Iowa State, USA. Firstly, the Boruta algorithm, stepwise regression, and multi-layer perceptron are employed to find the best subset of features that contribute to bridge deck deterioration. Then, four classification models were developed using the best feature subset of features, namely k-nearest neighbours, random forest, artificial neural networks, and deep neural networks. The hyperparameters of the models were optimized to get their best performance. The developed models showed comparable performance, and the random forest model outperformed the other models in prediction accuracy with fewer misclassifications. The developed models are thought to reduce field inspections and give insights into the most influential factors in bridge deck deterioration conditions.

FACTORS OF WAGE FORMATION IN AGRICULTURAL ENTERPRISES
Authors: SHYIAN Dmytro , KOTELNIKOVA Iuliia , SEVRIUKOVA Yelyzaveta
Published: November 2022

Introduction. It is emphasized that formation of wage level at the agricultural enterprises depends on a number of factors: the scale of the enterprise, productivity, volume and structure of sales, season work, etc. The degree of influence of these factors is an important aspect in calculating the income of employees and alternatives for their further increase. It should also be noted that today companies compete in the labour market for workers with appropriate qualifications. This forces them to increase wage level gradually.
The purpose of this article is to assess the impact of certain factors on the level and productivity of wages in agricultural enterprises of Kharkiv region.
Results. The number of staff at agricultural enterprises is not directly proportional to the increase in the area of enterprises, on the contrary, the growth of land area leads to a decrease in the number of employees. The growth of agricultural land at enterprises allows to increase the volume of marketable products and leads to an increase in wages. In most of the analyzed situations, an increase in the number of employees leads to a fall in wages. The low share of growth in marketable products indicates a very weak relationship between the level of labor productivity and the level of its payment, which raises a number of questions about employee motivation.
Conclusions. The factor of enterprise size has a significant impact on both productivity and the wage level. Larger businesses are more competitive. They can save on wages in absolute terms while increasing its level, which also creates a competitive advantage and allows to attract more qualified personnel. It has also been found that enterprises that have livestock industry in the structure of production significantly increase the level of employment compared to the enterprise, specializing exclusively in crop products. On the other hand, it is noted that dependence between labour productivity and its wage level is weak, which raises the question of the lack of a motivational mechanism at agricultural enterprises.
Key words: labour productivity, wages, enterprise size, staff motivation.

Published: November 2022

Coronavirus Disease 2019 (COVID-19) pandemic is the worst public health disaster in our modern history. The disease has almost put a pause on our daily lives and activities, slowed down the civilization, made millions of people lose their jobs, children’s education and future are at stake and the global economy spiraling down. To date, COVID-19 has caused 6.31 million deaths and 537 million cases worldwide. Unfortunately, the numbers are still counting albeit rather slowly. In Malaysia alone, as this abstract was written, the total number of deaths was 35,725 while the cumulative number of cases was 4,532,632. However, the good news is that the vaccination program that started more than a year ago has successfully and significantly reduced the number of active cases globally and slowly restored the world to order. In our higher education programs, postgraduate students were among the most affected during the pandemic. Students were only allowed into laboratories with restricted access. In many cases, they opted not to enter the laboratory and other research facilities due to the Movement Control Order (MCO), limited supply of chemicals and reagents, unavailability of laboratory staff for service and assistance, and for the fear of getting infected that may cause fatality with the virus that many of us are not familiar with. As a result, research activities in higher education stayed still; affected the students’ academic progression in terms of research and publications. Hence, what can we learn from this? What went wrong with our approaches? How do we prevent this from happening again? Have we learned the lesson? How do we move forward? This plenary lecture will dissect the root cause of the issue and offer various strategies from different angles and perspectives to ensure the same mistakes that we have made will never happen again. The whole idea is to bring back the glory of research on the right track.

Published: November 2022

The scope of data collection pertaining to particular outbreaks as well as general pandemics needs to be addressed accurately. All stakeholders in the crisis management need to be provided with precise information fairly and attentively. The urgency for the crisis solution through strategic innovations and well-coordinated services necessitates data analysis to be done rigorously in timely manners. It is to be subsequently shared with all the relevant agencies with the goal of benefiting the overall society. 

Accordingly, we need to develop coordination that are built upon competent human resources, comprehensive infrastructure, reasonable budget allocation, close cooperation of all agencies as well as highly patriotic policy makers. In our situation, even potential challenges to utilise the data had been pre-identified before the pandemic but the situation has been and will be more demanding during and after this pandemic era.

A focus group involving researchers from multi sectoral agencies during post-Omicron wave have recently revealed complex issues which had never been discussed openly. They include dismal response from the stakeholders as they could not grasp any immediate benefits of any study, wrong perception that the research is futile and time consuming, lack of cooperation from the ‘gate keepers’ of those who hold the authoritative section, poor data coordination on sharing between agencies i.e. MOH and MOHE on several issues, insufficient regulatory commitment on research policies, tendencies for unnecessary red tapes, and unhealthy rivalry between MOH and MOHE on overlapping research interests.

This pandemic experience has also reared the backward culture of standing pride based on institutional stratification. The competition to outnumber others by favouring certain research brands of certain institutions over others should be put aside. The determination to resolve the uncertainties of the epidemic in the future must be executed with full responsibility and mutual respects.

The end of these endemic transition era is still uncertain, but we can’t afford to wait much longer to put everything in perspective. While various technologies in data management continue to evolve, the turning point to achieve the ideal mark/goal of data availability is inevitably now.

Cancer incidence has been increasing over the years and it is the second leading cause of death globally [1]. The therapeutic strategies in killing the cancerous tissue while keeping the normal healthy tissue uninterrupted can be further improved by introducing nanoparticles (NPs) as radiosensitizers in radiotherapy. In pre-clinical research, a few nanoparticle elements had shown the potential to be radiosensitizers, such as gold, superparamagnetic iron oxide, platinum, and bismuth nanoparticles. Bismuth oxide nanoparticles (BiONPs) have been investigated as a potential radiosensitizer in radiotherapy due to their least toxic and biocompatibility properties. In addition, due to the presence of metallic nanoparticles in cells and their environment, more DNA damage will be introduced and thus enhance the radiation treatment efficacy.

 

This research project was conducted to evaluate the potential of BiONPs to increase the radiation treatment in MCF-7 breast cancer cells and their side effects on the non-targeted breast cancer cells. BiONPs were synthesized through the hydrothermal method, as established in the previous study [2]. The treated and control cells in flasks were irradiated with radiation doses between 0 to 12 Gy at a constant dose rate of 300 cGy/minutes in the beam field size of 10 cm x 10 cm for a 6 MV photon beam, delivered with linear accelerator Primus model (Siemen Healthcare, USA). The irradiated cell-conditioned medium (ICCM) was collected from the targeted cells and transferred into the non-targeted cells. The cell viability assay was employed to evaluate the effect of BiONPs on directly irradiated and non-irradiated cells.

 

In our prior work, the BiONPs had shown to boost radiosensitisation effects in treated cells compared to control cells, with a sensitisation enhancement ratio (SER) of 1.38 [3], as shown in Figure 1. The increased radiosensitisation effects might be attributed to the characteristics of BiONPs with a high effective atomic number (Z=83), which promotes radiation interaction, mainly radiation absorption and scattering. Meanwhile, the present study demonstrated that the non-irradiated MCF-7 cells could maintain their cell viability for more than 80% after 48 h incubation with ICCM treated with BiONPs at 2, 6, and 12 Gy. Furthermore, a comparable trend in cell viability was observed in non-irradiated MCF-7 cells for treated and control groups (p<0.05), as illustrated in Figure 2. This finding indicated that BiONPs are not harmful and do not contribute to side effects in non-targeted cells.

The present works have provided evidence that using BiONPs as radiosensitizers in radiotherapy is safe and does not significantly introduce side effects in the non-targeted cells. These data proved the impacts of BiONPs as a potential tool for a safe radiobiological enhancer that will benefit future radiation therapy strategies in cancer management.

The discovery of isocitrate dehydrogenase isoform 1 (IDH1) mutation as a key molecular marker has resulted in a change in glial tumour classification [1].  IDH1 mutations are commonly in gliomas, particularly in low-grade gliomas and secondary glioblastoma [2]. IDH1 p.R132H (c.395G>A) accounted for more than 90% of the mutation in IDH1/2 mutation and had a significant association with clinical outcomes. IDH1/2 mutations cause gain-of-function resulting in the formation of an oncometabolite, R-2-hydroxyglutarate instead of α-ketoglutarate implying a disruption of oxidative decarboxylation of Kreb’s cycle and other cellular mechanisms [3,4,5]. Immunohistochemistry (IHC) and Sanger sequencing is the most common approach used in molecular diagnostics. Nevertheless, both IHC and Sanger sequencing methods have shortcomings. IHC is prone to miss out on the mutation if the tumour samples are of poor quality, and it has also been reported to have low sensitivity when compared to sequencing-based techniques [6,7].

 

This study aimed to develop a sensitive, specific and cost-effective assay for genotyping IDH1 p.R132H mutations in glioma patients in order to shorten the time required for confirmatory diagnosis to be made. The tetra primer amplification refractory mutation system polymerase chain reaction (T-ARMS PCR) was used in this study to develop and validate the clinical applicability of the assay. A total of 61 glial specimens were collected and genomic DNA was isolated from all of them. All the samples were subjected to endpoint PCR and Sanger sequencing for mutation detection. T-ARMS PCR was developed and optimized prior to the screening of all the samples, and comparative mutation analysis was carried out.

Overall, IDH1 p.R132H mutation was found to be 45.90% (n=28/61) prevalent and was found to be significantly associated with gender, tumour subtypes and grading, and location of the lesions (p=<0.05). With an F1 score of 0.966, we reported T-ARMS PCR with sensitivity, specificity and accuracy of 100% (95% CI: 87.94-100.00%), 93.94% (95% CI: 80.39-98.92%) and 96.72%, respectively. To compare with published studies, a meta-analysis is T-ARMS PCR detected one case with IDH1 p.R132C (c.394C>T), howbeit the case could have a double mutation of p.R132C (c.394C>T) and p.R132H (c.395G>A) or single mutation of p.R132Y (c.394_395CG>TA). However, this study was able to detect IDH1 p.R132G (c.394C>G) mutation via PCR by Sanger sequencing whereas T-ARMS PCR excluded the mutation, suggesting the assay is very specific to IDH1 p.R132HH (c.395G>A) only.

Hereby, the performance of the T-ARMS PCR assay sheds a light that can be adapted for preoperative or intraoperative diagnosis.
Association of Predisposing Haplotype Snp-Markers of HBB Gene in Thalassaemia
Authors: Erwan Mohamad Naiem Firdaus , Wan Taib Wan Rohani
Published: November 2022

Most of the beta thalassaemia cases are heterogeneous at the molecular level. The genetic variation arises due to the mutation of a single beta-globin gene (HBB) on chromosome 11p15.5. Eventhough, the basis and natural history of this disorder are still not well understood and the clinical presentation in certain patients was not always correlated well with the single gene diagnosis [1].

 

The study aimed to evaluate the predisposing effect of HBB polymorphisms and their haplotypes in conferring beta-thalassaemia in Malaysia using a bioinformatics tool. Archived genotype data for five tagging SNPs of HBB gene assigned as c.9T/C, IVS2-16G/C, IVS2-74T/G, 3'UTR +314G/A and 3'UTR +316A/C across thalassaemia patient group (n=433) and normal control group (n=794) controls were retrieved from the year 2011 to 2016 at Institute for Medical Research (IMR). The genotype data were analysed for individual SNP-based association analysis and haplotype-based association analysis using SHEsis online software.

 

The study in all races in Malaysia showed significant association in four SNPs of the HBB gene (c.9T/C, P-value = 0.014; IVS2-16G/C, P-value = 0.017; 3'UTR+314G/A, P value = 2.08x108; 3'UTR+316A/C, P-value = 0.021). However, IVS2-74T/G did not show significant association with a P-value of 0.763 (Table 1). We further revealed two susceptible haplotypes in all races (haplotype TGTAA, P-value = 1.68x10-7, OR = 2.382 [1.707~3.325]; haplotype CCTGC, P-value = 0.003, OR = 1.300 [1.089~1.551]). Meanwhile, one protective haplotype observed was haplotype TGTGA (P-value = 2.99x10-7, OR = 0.625 [0.522~0.749]) (Table 2).

In conclusion, this study suggests the potential susceptible and protective haplotypes of the HBB gene in predisposing to beta-thalassaemia in Malaysia
