Research data management and services: Resources for different data practitioners
Authors: Mushi Gilbert
Published: December 2021

The emergence of data-driven research and demands for the establishment of Research Data Management (RDM) has created interest in academic institutions and research organizations globally. Some of the libraries especially in developed countries have started offering RDM services to their communities. Although lagging behind, some academic libraries in developing countries are at the stage of planning or implementing the service. However, the level of RDM awareness is very low among researchers, librarians and other data practitioners.

The objective of this paper is to present available open resources for different data practitioners particularly researchers and librarians. It includes training resources for both researchers and librarians, Data Management Plan (DMP) tool for researchers; data repositories available for researchers to freely archive and share their research data to the local and international communities.  

A case study with a survey was conducted at the University of Dodoma to identify relevant RDM services so that librarians could assist researchers to make their data accessible to the local and international community.

The study findings revealed a low level of RDM awareness among researchers and librarians. Over 50% of the respondent indicated their perceived knowledge as poor in the following RDM knowledge areas; DMP, data repository, long term digital preservation, funders RDM mandates, metadata standards describing data and general awareness of RDM. Therefore, this paper presents available open resources for different data practitioners to improve RDM knowledge and boost the confidence of academic and research libraries in establishing the service.
Publishing trends on research data management in Sub-Saharan Africa: A bibliometrics analysis
Authors: Kwanya Tom
Published: December 2021

Research data management is an umbrella term used to describe activities related to the creation, organisation, structuring, naming, backing up, storage, conservation, and sharing of research data as well as all actions that guarantee security of research data. As is often the case, researchers from Sub-Saharan Africa are lagging behind their counterparts in developed countries in embracing the best practices of research data management. One of the factors to which this slow pace of adoption of research data management could be attributed, is inadequate research on the subject. The purpose of this paper is to analyse the quantity, quality, visibility and authorship of publications on research data management in Sub-Saharan Africa. Bibliometrics approaches were used to analyse publications on research data management from, and on, Sub-Saharan Africa which are currently indexed in Google Scholar. The index was chosen because it is free and is reputed to have liberal selection criteria which do not favour, or discriminate, any discipline or geographic regions. Data was retrieved from Google Scholar using Harzing’s “Publish or Perish” software and analysed using VOSviewer. The findings of the study revealed that the quantity, quality, visibility and authorship collaboration of scholarly publications on research data management in Sub-Saharan Africa is low. The findings may be used by libraries and research institutions in Sub-Saharan Africa to develop and promote best practices in research data management as a means of enhancing their research output and impact.
Potential opportunities and risks of sharing agricultural research data in Tanzania
Authors: Katabalwa Anajoyce Samuel , Bates Jo , Abbott Pamela
Published: December 2021

Purpose: The purpose of this paper was to examine the potential opportunities and risks of sharing agricultural research data in Tanzania identified in the existing research literature.

Design/methodology/approach: The study involved a review of the literature on research data sharing practices.

Findings: The findings indicate that, research data sharing have significant positive benefits among researchers such as increase high research impact; enhancing international community collaboration among researchers with same interests; improving scientific transparency and accuracy of data (Rappert and Bezuidenhout, 2016); increasing research output whereby a single dataset can be used to generate more than one article by different authors; and many more. The risks hampering data sharing practices includes researchers’ fears that data will be scooped, poached or misused (Onyancha, 2016); unreliable electric power; lack of fund to support research data sharing activities; absence of institutional governmental support for data management; perceived lack of evidence benefits (Leonelli, Rappert and Bezuidenhout, 2018); and others. However, in Tanzania research data sharing is relatively new, thus, no any governmental agency mandating or encouraging research data sharing; therefore, there is no research data management; no research open data repositories and no research data sharing policy at any agricultural institution in Tanzania. The study recommends that agricultural researchers should be sensitized to share their data, research data policy and data repositories should also be established to support data sharing practices in Tanzania.

Originality and usefulness: From the available literature, this has been the first time that an effort has been made to examine the potential opportunities and risks of sharing agricultural research data in Tanzania. The study could be used by agricultural institutions and other institutions to assess the researchers’ needs in supporting research data sharing. Also, it can be used by the government and institutions to see the need of establishing open data repositories and open data policies to support research data sharing.
Establishment of data centre at Mzuzu University: A survey of anticipations and aspirations of key project stakeholders
Authors: Majawa Felix , Hall Ralph P.
Published: December 2021

Mzuzu University lost its Library as a result of a fire that took place on December 18, 2015. In response, the university established two processes to ensure the library services were not interrupted. The first process was to restore information services within six months by creating an interim Library. The second was to design a new library in collaboration with Virginia Tech’s School of Architecture and Design in the United States. A total of three conceptual designs were developed, from which Mzuzu University selected a final design. One key aspect of each conceptual design was a dedicated space for a data centre. The initial concept was that the data centre would support research activities at the University, within Malawi, and with international partners outside Malawi, such as Virginia Tech. This paper captures the anticipations and aspirations of the key stakeholders involved with the library design project at Mzuzu University in Malawi and Virginia Tech in the USA. Data were captured by a survey that was shared via email with 29 stakeholders. A total of 10 responded at Mzuzu University, and 12 responded at Virginia Tech. A key finding from the survey was the need to create clear plans for each aspect of the project to ensure the effective implementation of the data centre. Critical aspects to the project include staffing, equipment procurement, the management of the data centre, data literacy programming, and the long-term sustainability of the data centre. Developing a policy/process to guide the operations of the data centre was also found to be critical. The library construction began in February 2021 and is expected to end in February 2023. Having a clear plan for how the data centre could be operationalized will be essential to ensuring the centre is successful. The data centre will be a new facility for the university and this paper is a first step towards shaping the requirements of, and potential for, this new facility.

The Hospital Management Information System (SIMRS) functions as a medium for hospital information and hospital management. There are patient medical record data, which is the result of interactions between doctors and sufferer. Medical records are sensitive data so that the security of the hospital management information system needs to be improved to convince users or patients that the data stored on SIMRS is safe at attackers. There are several ways to improve system security, one of which is by threat modeling. Threat modeling aims to identify vulnerabilities and threats that exist in SIMRS. In this paper, threat modeling will use the STRIDE-model. The recognition with the STRIDE-model will then be analyzed and sorted according to the modeling with the STRIDE method. After the analysis is complete, it will be calculated and given a rating based on the DREAD method's assessment. The STRIDE method's results show that there are several threats identified, such as there is one threat on the user side, the webserver is five threats, and the database is three threats. The level of the threat varies from the lowest-level (LowL) to the highest-level (HiL). Based on the threat level, it can be a guide and sequence in improving and improving the security system at SIMRS, starting from the LowL to the HiL.

Video applications consume more energy on the Internet and can be accessed by electronic devices, due to an increase in the consumption of high-resolution and high-quality video content, presenting serious issues to delivery infrastructure that needs higher video compression technologies. The focus of this paper is to evaluate the quality of the most current codec, AV1, to its predecessor codec. The comparison was made experimentally at two video resolutions (1080p and 720p) by sampling video frames with various CRF/CQP values and testing several parameters analyses such as encoding duration, compression ratio, bit rate, Mean Square Error (MSE), and Peak Signal to Noise Ratio (PSNR). The AV1 codec is very great in terms of quality and file size, even though it is slower in terms of compression speed. The H.265/HEVC codec, on the other side, beats the other codec in terms of compression ratio. In conclusion, the H.265/HEVC codec is suggested as a material for obtaining a well compressed video with small file size and a short time.

The selection of outstanding students is an appreciation given by the boarding school to the students who have the highest scores. However, the election is usually still done subjectively and manually, and there is no support system in creating decisions, which make the selection process long and inaccurate. This study aims to implement a decision support system in determining outstanding students at Mamba'ussholihin Islamic Boarding School predetermined with criteria. The process of selecting uses the method Analytical Hierarchy Process (AHP) for weighting criteria and Operational Competitiveness Rating Analysis (OCRA) for ranking. The OCRA value obtained is in the form of Pi, which is ranked to get the best students. The findings show that the error consistency level is less than 10% and the consistency index value is accepted, so that it can be used as an initial weight with a relative number = 1. After calculating the OCRA method from the initial 75 alternative data, the top 10 alternative data obtained are in the form of the value of Pi will be entitled to an award as an outstanding student, so by applying these two methods it can speed up the results of the decision, it does not take a long time and the results obtained are also precise.

Game is a digital activity that is very popular in the modern era, both among young and old. One game that is very popular with E-sports competition is Warcraft 3. However, in 2020 it immediately fell because Blizzard company has released a new version of those games which is called warcraft 3 reforged. The purpose of this study was to find out the reason this could happen by using the heuristic evaluation of playability method. With this method, you can find the scale of the problem in a game that will be released. The data used for this study uses the player persona as the source of the assessment that will be carried out in this game. The player persona is created by providing 10 respondents who will be required to perform and assess each task given according to the scenario codes. The benefits of this research can be used to analyse the readiness of games to be released to the market and to find out customer tastes in RTS (Real Time Strategy) type games. This assessment is based on the mean rating which will later be categorized as the level of problem in the running of the game. The results of this study indicate that the mean rating in this game is 2.91 or can be referred to as the Major Usability Problem with the highest value of percentage with the highest problem category found in the game usability with a percentage value of 41.7%.

PDAM Loa Kulu Branch still uses sticks or poles as an indicator of the water level in the reservoir. Reservoir is a place to store clean water production from PDAM, the weakness of using sticks or poles is when the operator does not monitor continuously causing air loss when production becomes large. The goal of the study was to design a water-level prototype to control excess water in the reservoir. The method used is a prototype with the stage of gathering information through interviewing PDAM staff, creating and repairing prototypes and testing prototypes. The test used hardware consisting of Arduino uno r3, ultrasonic sensor hc-sr04, flowmeter sensor yf-s201, 16 x 2 lcd, relay module, buzzer, solenoid valve 12 V_dc, pump 12 V_dc and display measurement results in the visual studio application 2019. Our findings are that the length of reservoir charging with an average input discharge of 3.6 liters / minute is 2.93 minutes. As for the length of emptying the reservoir with an average output discharge of 1.06 liters / minute is 12.10 minutes. The conclusion of this study is that the system can monitor the water level inside the reservoir automatically and know the time needed for the feeling and emptying process of the reservoir.

Background: The prevalence of Diabetes mellitus (DM) is increasing worldwide. The complications of DM arising from hyperglycaemia are well documented and. However, there is a lack of data, poor awareness and information on hypoglycaemia in DM.

Objective: To describe the prevalence and factors associated with hypoglycaemia among patients with Type 2 Diabetes mellitus (DM).

Methods: This was a retrospective study of the clinical records of patients with Type 2 DM at the Family Medicine Clinic of a Nigerian teaching hospital from January 2019 to January 2020. The sociodemographic and clinical characteristics, including hypoglycaemia, Glycosylated Haemoglobin (HbA1c), Fasting and Random blood glucose, were retrieved.

Results: A total number of 570 patients were assessed, with a prevalence of 43 (7.5%) of hypoglycaemia. The mean age of the patients in the study was 58.2±10.9 years (range: 36-83 years). Metformin (557; 97.7%), Sulphonylureas (377; 66.1%), Dipeptidylpeptidase -4 inhibitors (137; 24.0%) and insulin (72; 12.6%) were the most prescribed anti-diabetic medications. hypoglycaemiaA majority (29; 67.4%) of the hypoglycaemia episodes occurred in the morning, while most (24; 55.8%) of the episodes of hypoglycaemia were mild. Mean age (t= 2.35; p = 0.019), presence of hypertension (X2 = 6.92, p = 0.008) and dyslipidaemia (X2 = 7.86, p = 0.005) were associated with hypoglycaemia.

Conclusions: The prevalence of hypoglycaemia in the Outpatient clinic was low, while the presence of comorbidities                                   (hypertension and dyslipidaemia) and age were associated with hypoglycaemia. There is a need for patient education and Self-Monitoring of Blood Glucose (SMBG) to prevent complications of hypoglycaemia. hypoglycaemia
