Diabetic Mellitus (DM) is a widespread chronic disease around the world, among which type 2 DM (T2DM) shared the majority. It caused multiple severe complications and consequently a high mortality rate. DM complications overwhelm jeopardize the patient’s quality of life. In response to the threats of such complications, some nutraceuticals were developed, including the highly praised bitter melon peptide (BMP). This study aims to apply the structural equation model in HBM. A theoretical model had been developed on the health belief model (HBM), and to test with the structural equation model (SEM) technique to examine the fitness of the theory and the data gathered in this research. A structural questionnaire was developed and used to collect 292 valid responses from DM patients. The SEM results indicated the fitness of the theory and the data were acceptable. Perceived susceptibility of DM complications and perceived benefits of nutraceutical were major predictors of intake behavior, and the association of perceived benefits and behavior was mediated by the patient’s self-efficacy on nutraceutical intake behavior.

Behavior maintenance for organizational change is the continuous behavior performance following an initial intentional change. This research examines the importance of factors that influence behavioral maintenance for organizational change. This study proposes a research model incorporating self-determination, regular-fit, self-concept, and habit theories to identify potential influencing factors of behavioral maintenance for organizational change in Ethiopia and quantify the importance level of these factors using ML techniques. A survey study was carried out in Addis Ababa, Ethiopia, with 310 valid responses. The comparison of five different ML techniques shows that Naive Bayes (GaussianNB) outperforms the other classification model.  Naive Bayes (GaussianNB) model-based feature importance analysis shows that perceived competency, perceived enjoyment, and perceived autonomy are the most prominent contributor to behavioral maintenance for organizational change. The results confirmed that the quality of individuals' motivation affects the extent to which individuals will engage in, and persist with, behaviors.
