Natural products have long been a vital source of novel lead compounds in drug discovery. Many drugs currently used as therapeutic agents have been derived from natural sources, with plants playing a particularly significant role. However, in recent decades, pharmaceutical companies have shown limited interest in natural product-based drug discovery, largely due to the inherent complexity of working with these substances. Recently, technological advancements have helped overcome many of these challenges, leading to a renewed scientific interest in exploring natural sources for drug development.........

This study presents a theoretical model for understanding repurchase intention for customers. An empirical study was conducted to examine the model. The results indicate that customers' intention to repurchase online is negatively associated with their perceived transaction cost, and perceived transaction cost is associated with resources of ethnic, personal, and indirect quanxi. Furthermore, impulse buying, and environment will influence repurchase intention when customers consider online shopping. According to the results of empirical study, implications and suggestion for future research are discussed.

This study examines the persistence and evolution of wealth equality across approximately one hundred generations following the Neolithic transitions—the period during which human societies shifted from foraging to farming economies. Using a combination of theoretical modeling, archaeological datasets, and inequality metrics such as the Gini coefficient, the analysis explores how land-based production, demographic expansion, and institutional development shaped long-term economic structures. Contrary to the assumption that agriculture immediately produced wealth concentration, results suggest an extended epoch of relative equality in early agrarian communities, constrained by limited capital accumulation, collective labor, and kin-based redistribution mechanisms.......

This study is motivated by the issue of delays in the Permanent Housing Infrastructure Project in Palu City, which constitutes a part of the post-disaster rehabilitation and reconstruction program. The objective of this research is to evaluate project schedule performance using the Schedule Performance Index (SPI), to identify the dominant work items affecting schedule performance through Pareto analysis, and to examine the root causes of delays employing Fault Tree Analysis (FTA) and a risk matrix framework. The research adopts a case study approach utilizing secondary data in the form of S-curves and project progress reports........
