Lean Management is a method that emphasizes reducing waste and increasing added value in healthcare service processes. Through a systematic literature review, this study identifies various aspects of Lean implementation in hospitals, such as reducing patient waiting times, optimizing resource utilization, and improving patient satisfaction. The findings reveal that Lean Management implementation not only supports operational efficiency but also enhances service quality and patient experience. The success of this method heavily depends on management support, active staff involvement, and adequate training. This study also highlights challenges such as resistance to change and budget constraints. These findings have significant implications for hospital managers and policymakers in formulating strategies to improve healthcare service effectiveness. Recommendations for future research include empirical studies examining Lean implementation in various hospital contexts, particularly in developing countries. This study aims to explore and analyze strategies for improving hospital operational efficiency through the Lean Management approach.

Hemophilia is a genetic disorder resulting from impaired blood clotting. This disorder can be caused by coagulation factor abnormalities due to a deficiency of clotting factors, including vitamin K. A lack of vitamin K disrupts the coagulation process, increasing the tendency for bleeding. This article aims to determine whether there is an influence of vitamin K levels on the blood clotting factors in hemophilia patients. Searching any information needed by analyzing kinds of papers of recent research from the year of 2014 until 2024. Online databases like PubMed, ScienceDirect, Google Scholar, Scopus, and ResearchGate  are utilized by inserting relevant keywords, such as hemophilia, blood clotting factors, vitamin K deficiency and extraction. From 10 articles reviewed, a relationship was identified between vitamin K levels and blood clotting factors in hemophilia patients. Individuals with severe hemophilia experience bleeding episodes characterized by delayed onset, as well as bleeding into muscles, joints, and other internal structures, including the brain. Hemophilia is typically diagnosed through the identification of low or absent levels of FVIII:C or FIX:C. The genes encoding FVIII and FIX are located on the long arm of the X chromosome. Hemophilia A and B are the only hereditary clotting disorders inherited in a sex-linked recessive pattern. Vitamin K levels can influence the blood clotting factors in hemophilia patients, particularly those factors synthesized artificially.

The 2024 Indonesian Presidential Election marked the fifth general election in the country, aimed at electing a new President and Vice President for the 2024–2029 term. Candidates competed to succeed the outgoing president, who had served two constitutional terms. A key aspect of this election was the candidate debates, where each candidate presented their vision, allowing the public to assess their policies. These debates were broadcast on platforms like YouTube, giving the public a space to comment. However, analyzing YouTube comments presents challenges due to the volume of data, language diversity, and informal expressions. Sentiment analysis, crucial for understanding public opinion, uses algorithms such as Naïve Bayes, which is based on Bayes' Theorem and assumes feature independence. Naïve Bayes is widely used in text analysis for its speed and simplicity. When applied to YouTube comments from the 2024 debates, the algorithm demonstrated its effectiveness, especially with a balanced dataset through random oversampling. It achieved 85.155% accuracy, high precision, recall, and an AUC of 96.8% on an 80:20 data split. Its fast classification time (0.000998 seconds) makes it suitable for real-time sentiment analysis, validating its use for political events. Future applications may incorporate advanced techniques like BERT for more sophisticated analysis.
