This study aims to establish an online shopping mall marketing strategy based on big data analysis methods. The customer cluster analysis method was utilized to analyze customer purchase patterns and segment them into customer groups with similar characteristics. Data was collected from orders placed over one year in 2023 at 'Jeonbuk Saengsaeng Market', the official online shopping mall for agricultural, fish, and livestock products of Jeonbuk Special Self-Governing Province. K-means clustering was conducted by creating variables such as 'TotalPrice' and 'ElapsedDays' for analysis. The study identified four customer groups, and their main characteristics. Furthermore, regions corresponding to customer groups were analyzed using pivot tables. This facilitated the proposal of a marketing strategy tailored to each group's characteristics and the establishment of an efficient online shopping mall marketing strategy. This study is significant as it departs from the traditional reliance on the intuition of the person in charge to operate a shopping mall, instead establishing a shopping mall marketing strategy through objective and scientific big data analysis. The implementation of the marketing strategy outlined in this study is expected to enhance customer satisfaction and boost sales.

The purpose of this study is to investigate the level of awareness and current performance level of self-directed learning (SDL) in nursing students. The core concepts were defined and a rubric was developed through literature review. It was applied later to subjects and the results were analyzed. According to the results, there were significant differences between the current performance level and the awareness level of SDL in all items. Students who chose nursing as a major due to their high school/SAT grades showed lower current performance level than others. There were insignificant differences in the current performance level influencing the next grade. The level of awareness showed insignificant differences according to the reason for selecting nursing as a major, satisfaction on major, and grade point average (GPA). In conclusion, there was a discrepancy between the level of awareness and the current performance level of SDL of nursing students, which indicates that they were aware of the necessity of SDL, but did not actually perform it. Nursing educators should seek for strategies that can improve SDL ability of their students as well as to better grasp the level of the SDL of their student and the current performance level of SDL to apply them to the instructional design.
