EARLY EVIDENCE ON THE XBRL ADOPTION PROCESS IN MALAYSIA: DRIVERS AND CHALLENGES ON THE TECHNOLOGICAL PERSPECTIVE
Authors: Ilias Azleen , K Ghani Erlane , Azhar Zubir 
Published: October 2020

Purpose: This study aims to identify technological factors and how these factors influence the XBRL adoption process of the regulators in Malaysia.
Methodology: This paper applied Rogers’s (1983) adoption process and DiPietro, Wiarda, and Fleischer’s (1990) Technological, Organisational, and Environmental (TOE) framework. The paper adopted a case study approach consisting of an interview and document analysis. The data has been analysed with thematic analysis.
Results: This paper shows ten (10) factors within the technological perspective—the relative advantage as driving factor while trialability are the challenging factor in the knowledge and persuasion phase. In the decision-making phase, compatibility of XBRL taxonomy and stability production of XBRL instance documents are the driving factors whilst stability of XBRL taxonomy, standardised XBRL taxonomy, standardised XBRL submission, availability of tools and software and observability are challenges in the XBRL adoption process. In the implementation and confirmation phase, the complexity of the XBRL taxonomy is considered a challenge in the XBRL adoption process.
Implications: The findings in this paper serve as strategies to the other regulators that have plans to adopt XBRL as well as to attract the different government agencies to start with XBRL for reporting.

Authors: Urek Handan 
Published: October 2020

The purpose of this study was to develop two Sudoku puzzles for undergraduate students which can be utilised in the context of introductory physical science courses in order to assist them to practice SI prefixes. For this reason, SI prefixes for decimal multiples and submultiples were addressed in two separate puzzles. To test the puzzles, a case study was conducted with 20 biology teaching students studying their first year in a state university in Turkey. Data were collected with the help of a questionnaire posed to the students before and after the application of the puzzles. According to the results, 18 students (90%) completed the puzzles successfully. In addition, the students agreed that solving the Sudoku puzzles made contributions to them in terms of practicing SI prefixes. It is recommended that the Sudoku puzzles developed in this study might be used efficiently for all undergraduate students taking courses such as general chemistry and physics.

Keywords: SI prefixes, educational games, Sudoku puzzles, introductory science courses.

Published: October 2020

Interactive whiteboards are provided in most schools in Oman, including those in the Al-Batinah North Governorate of the Sultanate, but many are not activated. Some teachers abandon them despite their presence and prefer to use the traditional blackboard or whiteboard for teaching. This study reveals the views of physics teachers in the Al Batinah North Governorate about the use of the interactive whiteboard for teaching physics. This study adopts a descriptive approach to collecting data from 377 male and female physics teachers, undertaken in the second semester of the 2017-2018 academic year. Statistical analysis shows that the teachers’ responses to the tool were positive and profound, and there were no significant differences in their views about the effectiveness of using interactive whiteboards for teaching due to the variables of gender, educational qualification, or years of experience. This result is satisfactory because of the similarity of the job environment for all members of the sample, which leads to the absence of a difference in the viewpoints of male and female teachers. In light of the results, the study recommends holding workshops and training courses for teachers to develop their skills in using the interactive whiteboard in teaching and conducting similar studies in other provinces with larger samples to generalize the results.

Introduction: Chromosome abnormalities contribute to about 10% of cases of premature ovarian insufficiency. Most are associated with X chromosome. Fragile mental retardation 1 (FMR1) gene premutation has an estimated prevalence of 1% - 7% in sporadic cases and up to 13% in familial cases. Our aim was to describe the clinical characteristics, cytogenetic and FMR1 testing of a Portuguese population with premature ovarian insufficiency.Material and Methods: Women diagnosed with premature ovarian insufficiency in a Portuguese tertiary centre were retrospectivelyanalysed. Data were retrieved from electronic medical records including clinical characteristics, cytogenetic and FMR1 testing. The main outcome measures were the prevalence of chromosome abnormalities and FMR1 premutation in a Portuguese population with premature ovarian insufficiency.Results: Ninety-four patients were included, with a median age at menopause of 36 years. The prevalence of chromosome abnormalities was 16.5% (14/85) and most were X chromosome related (78.6%). The prevalence of FMR1 premutation was 6.7% (6/90). The prevalence of karyotypic abnormalities or FMR1 premutation did not differ significantly between familial and sporadic cases. Neither chromosome abnormalities nor FMR1 premutation influenced age at menopause or follicle stimulating hormone levels at diagnosis in premature ovarian insufficiency patients.Discussion: This is the first study describing the clinical characteristics and both cytogenetic and FMR1 testing in a Portuguese population with premature ovarian insufficiency. The rate of chromosome abnormalities in our sample was higher than in other populations, while the prevalence of FMR1 premutation was similar to previous reports.Conclusion: Our results underline the importance of genetic screening in premature ovarian insufficiency patients in both etiological study and genetic counselling.

Published: October 2020

Abstract
Background: Invasion depth is an important index for staging and clinical treatment strategy of bladder cancer (BCa). The aim of this study was to investigate the feasibility of segmenting the BCa region from bladder wall region on MRI, and quantitatively measuring the invasion depth of the tumor mass in bladder lumen for further clinical decision-making. This retrospective study involved 20 eligible patients with postoperatively pathologically-confirmed BCa. It was conducted in the following steps: (1) a total of 1159 features were extracted from each voxel of both the certain cancerous and wall tissues with the T2-weighted (T2W) MRI data; (2) the support vector machine (SVM)-based recursive feature elimination (RFE) method was implemented to first select an optimal feature subset, and then develop the classification model for the precise separation of the cancerous regions; (3) after excluding the cancerous region from the bladder wall, the three-dimensional bladder wall thickness (BWT) was calculated using Laplacian method, and the invasion depth of BCa was eventually defined by the subtraction of the mean BWT excluding the cancerous region and the minimum BWT of the cancerous region.Results: The segmented results showed a promising accuracy, with the mean Dice similarity coefficient of 0.921. The “soft boundary” defined by the voxels with the probabilities between 0.1 and 0.9 could demonstrate the overlapped region of cancerous and wall tissues. The invasion depth calculated from proposed segmentation method was compared with that from manual segmentation, with a mean difference of 0.277 mm.Conclusion: The proposed strategy could accurately segment the BCa region, and, as the first attempt, realize the quantitative measurement of BCa invasion depth.

Abstract
Background: Epidemiological studies examining the association between β-carotene intake and risk of fracture have reported inconsistent findings. We conducted a meta-analysis to investigate the association between β-carotene intake and risk of fracture.

Methods: We systematically searched PubMed, EMBASE and Cochrane library databases for relevant articles that were published until December 2019. We also identified studies from reference lists of articles identified from the clinical databases. The frequentist and Bayesian random-effects model was used to synthesize data.

Results: Nine studies with a total of 190,545 men and women, with an average age of 59.8 years, were included in this meta-analysis. For β-carotene intake (1.76 -14.30 mg/day), the pooled risk ratio (RR) of any fracture was 0.67 (95% Credible Interval (CrI): 0.51-0.82; heterogeneity: P = 0.66, I 2 =0.00 %) and 0.63 (95%CrI: 0.44-0. 82) for hip fracture. By study design, the pooled RRs were 0.55 (95% CrI: 0.14-0.96) for case-control studies and 0.82 (95% CrI: 0.58-0.99) for cohort studies. By geographic region, the pooled RRs were 0.58 (95% CrI: 0.28-0.89), 0.86 (95% CrI: 0.35-0.1.37), and 0.91(95% CrI: 0.75-1.00) for studies conducted in China, the United States, and Europe, respectively. By sex, the pooled RRs were 0.88 (95% CrI: 0.73-0.99) for males and 0.76 (95% CrI: 0.44-1.07) for females. There was a 95% probability that β-carotene intake reduces risk of hip fracture and any type of fracture by more than 20%.

Conclusions: The present meta-analysis suggests that β-carotene intake was inversely associated with fracture risk, which was consistently observed for case-control and cohort studies. Randomized controlled trials are warranted to confirm this relationship.

Abstract
Background: The patients’ acceptance of a treatment plan and their subsequent cooperation play a crucial role in achieving the best results in orthodontic treatments. Evidences show some personality traits such as general self-efficacy (GSE) and some dental traits such as severity of malocclusion are correlated with motivation of orthodontic treatment. These factors may predict the patients’ compliance and acceptance in using removable orthodontic appliances. This cross sectional study was conducted to assess the correlation of GSE and the severity of malocclusion with patients’ acceptance in using removable orthodontic appliances.Methods:This study recruited 50 patients aged 10-12 years who required removable orthodontic appliances. The severity of malocclusion was determined using the index of orthodontic treatment need (IOTN) before the onset of treatment and GSE of participants were assessed using GSE scale self-report. The acceptance questionnaire was proposed to the patients on first (T1), third (T2), and sixth (T3) month after the delivery of the appliance.Results: The GSE score had a statistically significant correlation with the total score of the acceptance questionnaire, subscale score of satisfaction with the appliance during eating and oral hygiene practice, duration of usage of the appliance, and interest in using it (P<0.05). The IOTN had no significant correlation with the acceptance questionnaire.Conclusions: Our findings substantiate the role of the GSES, concurrently declining the role of the IOTN in prediction of 10-12-year-old children's acceptance and cooperation in treatment of malocclusion with removable appliances.

Abstract
Background: Impairment of activities of daily living (ADL) due to hemorrhagic gastroduodenal ulcers (HGU) has rarely been evaluated. We analyzed the risk factors of poor prognosis, including mortality and impairment of ADL, in patients with HGU.Methods: In total, 582 patients diagnosed with HGU were retrospectively analyzed. Necessity to look for care facilities to admit or requirement of home modifications during the hospitalization period was defined as ADL decline. The clinical factors were evaluated: endoscopic features, need for interventional endoscopic procedures, comorbidities, symptoms, and medications. The risk factors of outcomes were examined with multivariate analysis.Results: Advanced age (> 75 years) was a significant predictor of poor prognosis, including impairment of ADL. Additional significant risk factors were renal disease (odds ratio [OR], 3.43; 95% confidence interval [CI], 1.44–8.14) for overall mortality, proton pump inhibitor (PPIs) usage prior to hemorrhage (OR, 5.80; 95% CI, 2.08–16.2), and heart disease (OR, 3.05; 95% CI, 1.11–8.43) for the impairment of ADL. Analysis of elderly (> 75 years) subjects alone also revealed that use of PPIs prior to hemorrhage was a significant predictor for the impairment of ADL (OR, 8.24; 95% CI, 2.36–28.7).Conclusion: In addition to advanced age, the presence of comorbidities was a risk of poor outcomes in patients with HGU. PPI use prior to hemorrhage was a significant risk factor for the impairment of ADL, both in overall HGU patients and in elderly patients alone. These findings suggest that the current strategy for PPI use needs reconsideration.
