APPLICATION OF SOFT SETS TO ASSESSMENT OF MATHEMATICAL MODELLING SKILLS
Authors: Voskoglou Michael Gr. 
Published: January 2022

Formulation of the problem. Formulation of the problem. Mathematical modelling is a very important component of mathematics education, because by applying the mathematical theories to practical needs of our everyday life increases the student interest for mathematics. The main steps of the mathematical modelling process include analysis of the given real world problem, formulation of the problem and construction of the mathematical model (mathematization), solution and control of the model and implementation of the final mathematical results to the real situation. Mathematization possesses the greatest difficulty among the steps of the MM process, because it involves a deep abstracting process, which is not always easy to be achieved by a non-expert. It is sometimes, however, the transition from the solution of the model to the real world (control and/or implementation of the model) that presents difficulties for students too. An example is given to illustrate this remark.
Materials and methods. In this paper soft sets are used as tools for developing a model for assessing human activities in a parametric manner and an example is presented (assessment of football players performance) to illustrate its applicability under real situations. A soft set, being a parametrized family of subsets of the universal set of the discourse, is a generalization of the concept of fuzzy set designed on the purpose of dealing with the existing uncertainty in a parametric manner. The theory of soft sets has found many and important applications to several sectors of the human activity like decision making, parameter reduction, data clustering and data dealing with incompleteness, etc.
Results. The soft set assessment model is applied for evaluating student mathematical modelling skills with respect to the parameters excellent, very good, good, mediocre, and failed. It serves both for assessing the general performance of a student class and the individual performance of each student with respect to the steps of the mathematical modelling process.
Conclusions. The constructed in this paper model is very useful in cases where the assessment has qualitative rather than quantitative characteristics and could also be applied to a variety of other cases for assessing human and/or machine (e.g. computer programs) activities.
Towards SDG3: Empowering Non-Nephrologists to Perform Peritoneal Dialysis in District Settings
Authors: Sarfo Anima , Agyeman Appiah Nana Akua Bakoma , Amoah Abigail , Obeng Esther , Antwi Sampson 
Published: January 2022

BackgroundSDG3 stipulates good health and well-being for all. Dialysis has remained a specialized skill for nephrologists. In settings without nephrologists, many die from Acute Kidney Injury (AKI). In 2014, the International Society of Nephrology (ISN) launched the 0by25 initiative for zero death from AKI globally. In this paper, we report on training of district health practitioners in the performance of PD for AKI using improvised means.
Methods
PD training workshops with hands-on experienced were organized in 7 regional capitals in Ghana. Topics taught included:

Recognition of a child with AKI
Principles of PD
Indications for dialysis therapy and writing of PD prescription
Technique in insertion of PD catheter plus video exhibit
Catheters suitable for use as PD catheters
Fluids suitable for use as dialysate
Performing the PD exchanges
Complications related to PD
Infection prevention in PD.

Results
A total of 150 health workers made up of 131 Doctors or Physician Assistants and 19 nurses were trained across Ghana. Feedback from trainees indicates that 42 PDs have been carried out in 7 district hospitals. 25 (59.5%) of the 42 dialyzed children survived and recovered renal function.
Conclusion
It is possible to build the capacity of non-nephrologists to identify AKI and institute PD in district level hospitals so SDG3 could be realized. Such achievement will also help to realize the ISN 0by25 initiative especially in resource-limited settings where nephrology expertise is lacking.

Published: January 2022

Background Pediatric heart diseases (PHDs), comprising congenital heart diseases (CHDs) and acquired heart diseases (AHDs) are significant contributors to non-communicable diseases in children. CHDs alone occur in 0.8-1.0% live births globally. Data on echocardiogram diagnosed PHDs in Ghana however is lacking. We set out to describe the echocardiogram diagnosed prevalence of the various PHDs, their age profile and change in trends over an eleven-year period in children less than sixteen years seen in Kumasi.
MethodsWe retrieved archived first echocardiogram scan reports from January 2010 through December 2020, and extracted the diagnosis, scan date and sex of the patients. PHDs were categorized into CHDs and AHDs and proportions of the top five reported respectively. Observed trends in proportion of types of PHDs and age at first diagnosis were computed. Data was collected using Microsoft® Excel and analyzed with R statistical software.
ResultsPHDs were present in 49.9% (2474/4962) of the scans done with 51.5% (95%CI: 49.5-53.5) being males and 93.3% CHDs. The number of different diagnoses were 3344 as some of the patients had multiple diagnosis. Of these, the top five CHDs were Ventricular Septal Defect (699, 20.9%), Atrial Septal Defect (634, 19.0%), Patent Ductus Arteriosus (576, 17.2%), Tetralogy of Fallot (318, 9.5%) and Atrio-Ventricular Canal Defect (222, 6.6%). That for AHDs were Rheumatic Heart Disease (61, 1.8%), Dilated Cardiomyopathy (46, 1.4%), pericardial effusion (29, 0.9%), Hypertrophic Cardiomyopathy (26, 0.9%) and Infective Endocarditis (14, 0.4%). Proportion of various PHDs stayed constant over the years (p=0.129). The median (IQR) age in months for acyanotic CHDs (6, 1.5-18), cyanotic CHDs (15.0, 4.0-36.0) and AHDs (72.0, 19.0-120) were significantly different (p<0.001). Age at diagnosis reduced by 0.46 months per year, (95%CI: 0.01 to 0.92, p=0.046) over the 11-year period.
ConclusionPrevalence of CHDs and AHD are similar to other reports worldwide and has remained largely unchanged over the 11-year period. Age at first diagnosis however is reducing for all PHDs.

Authors: Osei-Bonsu Angela , Tannor Abena , Hammond Charles , Dogbe Joslin 
Published: January 2022

Background
According to the Ghana Multiple Indicator cluster survey 2011, 1 in 4 Ghanaian children aged 36-59 months is estimated to have a delay in their development (cognitive, learning, socioemotional and physical). Although the exact prevalence of autism spectrum disorder (ASD) in the country is unknown, these children are a particularly under-served population in Ghana, suffering from late identification and poor access to evaluation and treatment.Aim:
To establish standard care pathways in the public health sector for the management of ASD in the Ashanti Region of Ghana by August 2021.
Method
A multidisciplinary guiding coalition was established to conduct a fish-bone root cause analysis via one-on-one interviews and focused group discussions with major stakeholders to understand the primary cause of the problem. A simple referral process map was then designed by the group. After an extensive literature search using google scholar and PubMed, the 23Q screening tool, originally designed in Uganda, for developmental assessment of children aged 2-9years was selected and locally validated. The tool was then piloted in 15 schools across 9 out of 43 districts assemblies in the Ashanti Region.
Results
23 out of 43 special needs coordinators in Ashanti Region were trained in the use of the screening tool. Across the 15 schools visited, the tool identified developmental disorders in a total of 427 children, aged 3-17years, with an average age of 9years. 18% (n=78) of these children aged between 3 and 17years, were flagged by ASD specific questions with 7% (32) aged between 3-9years.
Conclusion
Autism awareness is evolving in Ghana. This project seeks to ultimately establish the burden of ASD in Ghana and connect pediatricians, medical officers, special education teachers, therapists, and families in an all teach, all learn collaboration which would set the framework for a national system of coordinated care for children with ASD.
