According to expert opinions and literature reviews, the dangers faced by firefighters have been determined to be thermal, physical, biological, environmental, and chemical.MethodsAnalytical Hierarchy Process (AHP) and Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) methods were used in the study. The AHP method was preferred because it is a systematic decision-making method that includes both ranking and comparison techniques. The PROMETHEE method was preferred because it provides the opportunity to make effective decisions in a very short time by basing the decision-making process on a scientific basis. In addition to the graphical representation of the ranking of alternatives, it offers decision-makers the opportunity to make various statistical analyses.ResultsThe weights of the hazards were calculated using the AHP method. Physical hazards accounted for the highest weight. PROMETHEE was used in the ranking of wearable smart technological products to protect the health and safety of firefighters.<b>Conclusions:</b> Products are listed as Personal Protection System, PROeTEX PPE, Wearable IoT Device, Flame Resistant Shirt, Fall Detection Systems, Smart Wearable Underwear, and WASP.

Because many medical domain datasets are class imbalanced, data resampling methods, including oversampling, undersampling, and hybrid sampling methods, have been widely applied to rebalance the training set, facilitating effective differentiation between majority and minority classes.ObjectiveHerein, we examine the effect of incorporating both data discretization and data resampling as steps in the analytical process on the classifier performance for class-imbalanced medical datasets. The order in which these two steps are carried out is compared in the experiments.MethodsTwo experimental studies were conducted, one based on 11 two-class imbalanced medical datasets and the other using 3 multiclass imbalanced medical datasets. In addition, the two discretization algorithms employed are ChiMerge and minimum description length principle (MDLP). On the other hand, the data resampling algorithms chosen for performance comparison are Tomek links undersampling, synthetic minority oversampling technique (SMOTE) oversampling, and SMOTE-Tomek hybrid sampling algorithms. Moreover, the support vector machine (SVM), C4.5 decision tree, and random forest (RF) techniques were used to examine the classification performances of the different approaches.ResultsThe results show that on average, the combination approaches can allow the classifiers to provide higher area under the ROC curve (AUC) rates than the best baseline approach at approximately 0.8%-3.5% and 0.9%-2.5% for twoclass and multiclass imbalanced medical datasets, respectively. Particularly, the optimal results for two-class imbalanced datasets are obtained by performing the MDLP method first for data discretization and SMOTE second for oversampling, providing the highest AUC rate and requiring the least computational cost. For multiclass imbalanced datasets, performing SMOTE or SMOTE-Tomek first for data resampling and ChiMerge second for data discretization offers the best performances.ConclusionsClassifiers with oversampling can provide better performances than the baseline method without oversampling.
