The aim of this study was to estimate the caseload with regard to the proportion of work-related medical cases in factory workers and to survey knowledge of and attitudes to occupational medicine among doctors in an industrial area in Singapore. To this end, a self-administered questionnaire was given to 74 general practitioners in the industrial district of Jurong in Singapore. Overall, there ...

’n Nuwe insulienpreparaat met 100 eenhede per milliliter (U-100) word nou in Suid-Afrika bemark. Hierdie sterkte skakel aan by die wêreldwye metriseringstendens en is reeds in sommige lande die enigste insuliensterkte wat toegelaat word. Die gebruik van hierdie preparaat vergemaklik die selftoediening van insulien vir diabetiese pasiënte aangesien daar minder kans vir doseringsfoute is en ’n kl...

The energy crisis in Europe 2022 and its consequences have brought changes to approaches towards the issue of security, policy, ability react phenomena market a short period time. European countries that are dependent on Russian fossil fuels faced numerous dilemmas challenges 2022. This paper aims analyse instruments policies introduced as reactions countries, specifically with examples Poland ...

Our project analyzes the United States domestic airport network. We attempt to determine which airports are most vital in maintaining the underlying infrastructure for all domestic flights within the United States. To perform our analysis, we use data from the first quarter of 2010 and use several methods and algorithms that are frequently used in network science. Using these statistics, we ide...

This paper studies a strategic supply chain management problem to design robust networks that perform well under both normal conditions and when disruptions strike. We present a mixed-integer programming model whose objective is to minimize the nominal cost (the cost when no disruptions occur) while reducing the disruption risk using the p-robustness criterion (which bounds the cost in disrupti...

Modeling the complex decision problems faced in the coordination of disaster response as a scheduling problem to be solved using an optimization algorithm has the potential to deliver efficient and effective support to decision makers. However, much of the utility of such a model lies in its ability to accurately predict the outcome of any proposed solution. The stochastic nature of the disaste...

This paper studies a strategic supply chain management problem to design reliable networks that perform as well as possible under normal conditions, while also performing relatively well when disruptions strike. We present a mixed-integer programming model whose objective is to minimize the nominal cost (the cost when no disruptions occur) while reducing the disruption risk using the p-robustne...

Disruption management has recently become an active area of research. In this study, an extension is made to consider the fact that some products may deteriorate during storage. A productioninventory model for deteriorating items with production disruptions is developed. Then the optimal production and inventory plans are provided, so that the manufacturer can reduce the loss caused by disrupti...
