Calibration and verification of weighing scales installed in hospitals and healthcare centres is indispensable to ensure its performance accuracy. A study was conducted to ascertain the performance of weighing scales in Ilala, Kinondoni, and Temeke hospitals located in Dar es Salaam region. The study administered fifty questionnaires to gather data from individuals working in these hospitals and healthcare centres as well as performing actual test of the installed scales. During the actual test, it was found that 38% of the scales delivered correct results, 48% were partially correct and 14% were incorrect. It was also found that 18% of tested scales were verified and stamped while 82% were neither stamped nor verified. Furthermore, the findings from the respondents show that 80% of the scales have not been repaired since they were purchased, 2% were repaired only once a year, while 18% were repaired at least once a year. It is concluded that the overall performance of the hospitals’ weighing scales was notsatisfactory. This is because only 38% of the scales delivered correct results while 62% delivered uncertain results. It is recommended that hospitals and healthcare centres should purchase weighing scales from the approved supplier by the Weight and Measures Agency (WMA) as this will minimize the poor performance of the scales used. It is also recommended that the Weight and Measures Agency (WMA) should establish a regulation that subjects the scales to metrological inspection and control, as well as raising awareness of the users of the scales on their proper use and storage

This study mainly focused on exploring the roles of standardisation and quality infrastructure systems in aiding trade and sustainable development within the African continental free trade area. This is a conceptual study. It was established that facilitating trade and sustainable development lead to attaining economic growth of any developing country. Several factors are involved in facilitating trade and sustainable development, including quality infrastructure and standardisation. These two factors foster free trade area establishment by eliminating trade barriers within the African countries. The factors can also assist speeding up the delivery time, reducing goods rejection at crossing borders, environmental protection by adhering to the ISO 14000 series of standards, add competitive advantages and many more. Despite all these benefits, African countries still are challenged regarding effective metrology institutes. To be able to foster a free trade area within African countries, each country needs to establish an influential metrology institute for carrying out all metrological activities which would provide assurance and global recognition to their products and services.

Satisfying students, especially in the service institutions, is a bit complicated due to the diverse and dynamic nature of students when it comes to service provision compared to products. This study thus aimed at stratifying students’ satisfaction requirements at higher learning institutions using the Kano model. Qualitative data were collected from a primary source through interviews and questionnaires. A qualitative approach assisted in collecting forty-six requirements from college students. The Kano model analysed the forty-six requirements. One-dimensional requirements were twenty-three, must-be (14), attractive (4), indifferent (3) and reverse (2). For a college to satisfy students, it has to focus on the fourteen must-be attributes as they are the basic requirements for satisfaction. Subsequently, a college needs to increase students’ satisfaction rate by focusing on one-dimensional attributes by increasing their performance. Nevertheless, to delight students, attractive attributes requirements should be fulfilled whilst paying less attention to indifferent attributes and getting rid of reverse attributes. Regarding the results on the satisfaction and dissatisfaction coefficients, those with maximum coefficients of satisfaction should be considered first during the improvement processes, followed by those with less coefficient of satisfaction. This would impact students’ satisfaction rate positively and eventually would attract the number of students in the respective colleges through wordof-mouth from the current students.

Monitoring the inflation of tyre pressure plays a significant role in ensuring safety of motor vehicle users both private and public. Accurate measurement of tyre inflation pressure requires a tyre pressure gauge, which is consistent and that complies with other metrological characteristics. Proper metrological control of the manufactured and imported gauges is paramount to measure the accuracy of the tyre pressure. The control of conformity to metrological characteristics for new and those in use is still uncertain, their accuracy is also not known to both users and their customers who inflate pressure in their motor vehicle tyres. This study assessed the legal metrological control of the tyre inflation pressure gauges in Dar es Salaam. The assessment was done by taking a sample of 255 bus drivers, 159 inflation pressure gauge users and also 159 inflation pressure gauges located in Kinondoni. The results reveal that users are aware of calibration and verification of their gauges. It was indicated that 89.9% of 159 respondents had no idea of calibrating their instruments while 10.1% were aware, 96.9% never attended any training regarding calibration. About 98.1% had never been visited by any regulatory authority for calibration and verification. It was observed that only 18.2% of 159 tested instruments were accurate while the remaining were deviating from 40 % and 30% for positive and negative deviation respectively. The government should consider adding the instruments in the list of those subjected to legal metrological control to have accurate tyre pressure inflation gauge. The additional of the instruments will enable the regulatory authorities to carry out calibration and verification to the manufactured and imported tyre pressure inflation gauges in the country and getting rid of counterfeit and inaccurate instruments
