A Machine Learning Model for Local Market Prediction Using RFM Model
No full textThis study explores the application of machine learning for local market prediction in e-commerce. By leveraging the RFM segmentation method, the model predicts product sales based on user shopping patterns. The RFM score, calculated using recency, frequency, and monetary values of customer purchases, segments customers into distinct categories. The research utilizes a dataset obtained through seven parameters and performs data preprocessing. K-Means clustering then classifies customers into Low, Medium, and High levels based on their RFM scores. Customers in the Low category exhibit low purchase activity but high product browsing. The Medium segment displays consistent purchases of a limited product range. High-level customers demonstrate frequent purchases with significant spending. The identified customer segments enable targeted marketing strategies. For Low-level customers, discounts or product feature promotions can incentivize purchases. Combining product offerings can entice Medium-level customers to explore new products. Finally, High-level customers can be engaged through loyalty programs offering rewards. This approach empowers ecommerce sellers to tailor marketing strategies for each customer segment, enhancing market dominance

No full textManaging blood glucose levels is critical for preventing complications associated with type 2 diabetes mellitus (T2DM). Physical activity has been shown to be an effective strategy for glucose control, with various forms of exercise yielding different results. This research aims to explore the effects of body weight training and series 7 diabetes dance on reducing blood glucose levels in patients with T2DM, and to compare the efficacy of these two interventions in achieving glucose control. The type of research was a quasi-experiment with a two groups pre-test post-test design. The series 7 diabetes dance group performed the exercise 4 times a week (duration: 170 minutes 8 seconds/week), while the body weight training group performed exercise 3 times a week (8 movements, number of repetitions close to failure, circuit system, 3 sets per training session). Both groups were doing an exercise program for three months. The research sample was for about 16 patients of type 2 diabetes mellitus (8 people per group, devided randomly), taken by using non probability sampling technique, purposive sampling type (effect size 1.6, significant level (α) 0.05 and Power 0.8). The data analysis used the paired sample t test and the independent t test with a significance level of α = 0.05.The results showed that 1) there is no significant effect of series 7 diabetes dance towards the decreasing the level of blood sugar of the patients with type 2 diabetes mellitus), 2) there is a significant effect of body weight training towards the decreasing level of blood glucose of the patients with type 2 diabetes mellitus, 3) dody weight training is more effective in decreasing the level of blood glucose of patients with type 2 diabetes mellitus compared to series 7 diabetes dance. Future research must be carried out as a true experiment with a larger number of samples and with the HbA1c research instrument
Understanding barriers to optimal supervision and delivery of the NationalCertificate (vocational) curriculum through TVET college lecturers’reflective evaluations
No full textPropounded by reflective theory, this qualitative case study drew on TVET lecturers\u27 reflective evaluations of factors that they considered to have a bearing on optimal supervision and delivery of the National Certificate (Vocational) curriculum. Data were collected from participants across three campuses of a TVET college in the Eastern Cape Province, South Africa. Twelve lecturers of different seniority were purposively sampled and interviewed in two focus group sessions. The first focus session involved six participants: four post-level 2 and two post-level 3 personnel recognized by the South African Council for Educators (SACE) as office-based lecturers and classified within the middle management echelon of curriculum management and supervision. The second focus group session entailed six post-level 1 personnel (recognized by SACE as classroom-based lecturers ). The findings problematized (1) the Depart- ment of Higher Education and Training’s failure to monitor and evaluate curriculum delivery processes; (2) a lack of comprehensive professional development opportu- nities for classroom-based lecturers; (3) poor coordination of work-integrated learning (WIL) programs and processes; (4) curriculum supervisors’ limited time for classroom visits due to heavy administrative workload; (5) the absence of communities of prac- tice for knowledge sharing purposes among lecturers; (6) students\u27 language barriers, which led to low pass rates; (7) shortage of qualified student support practitioners and onsite academic support programs; and (8) unreliable Internet connectivity and rigid access to technology infrastructure. The study recommends that the college leadership should address these challenges by applying all possible measures to optimize lecturers\u27 curriculum supervision and delivery practices at the selected TVET college
