Lean six sigma applied as an improvement tool. Case study: descapote activity in road infrastructure company
The Lean Six Sigma methodology promotes process quality improvement. It has an integrated approach, among its most potential characteristics we find that it identifies, prioritizes and eliminates the origin of problems and helps to develop effective solutions that are maintained in the organization. This article presents a study on the Lean six sigma methodology applied specifically in the road infrastructure sector in Yopal, Casanare. Additionally, it is important to mention that this type of companies do not implement this type of methodologies to solve their problems. For the development of this research, different tools applied in the mission process of this company were used, which was carried out through the observation of 300 unskilled labor workers. The most relevant results show that the company presents non-contributory times, that is to say, lost times in the activities of stripping and hydraulic structures as a consequence of the defects of accumulation of material and liberation of the work area. Likewise, it is important to clarify that the results showed that the accumulation of material in the activities is due to the lack of training to the personnel on material handling, lack of supervision by the engineers, lack of a storage point for the material, among others. Finally, in conclusion of the research results, it can be mentioned that the methodology allows us to propose tools such as the 5's, as it was in this study, in order to improve persistent problems faced by road infrastructure companies.

Analysis of Bitcoin Halving and its Influence on the price
This article analyzes the Bitcoin halving phenomenon and its impact on the price of this cryptocurrency, with a special focus on the event scheduled for April 2024. To achieve this, a mixed-methods approach was applied, combining a literature review and historical data analysis of previous Bitcoin halvings. The results highlight that, although halvings do not produce immediate effects on price, significant value increases are observed in the medium and long term, attributable to the reduction in the issuance rate of new Bitcoins and the perception of scarcity. The analysis also reveals that external factors, such as institutional adoption and global economic conditions, influence market dynamics. It is concluded that halving is a key mechanism in the stabilization and appreciation of Bitcoin, reinforcing its role as a deflationary asset in the digital economy.

Evaluation of materials for prosthetic sockets: performance criteria in additive manufacturing processes
The main problem addressed by this research is the lack of accessibility to personalized and economical sockets for the disabled, since traditional sockets can be expensive and time consuming to manufacture, which makes their acquisition difficult. Additionally, the lack of customization prevents prostheses from being adjusted to the individual needs of each patient, limiting their mobility and causing discomfort. The socket is a critical part of the prosthesis that must fit perfectly to the patient's residual limb to ensure a secure and stable connection between the prosthesis and the limb. Traditional socket fabrication can be a lengthy and costly process that requires several doctor visits and tests, which is difficult for patients who live in remote areas or have difficulty moving around. That is why, this project aims to select the optimal material for the manufacture of the prosthesis based on a process by contribution of thread, which requires that the material has similar properties to conventional materials such as polyethylene (PE) and polypropylene (PP) this was achieved through the use of software for material selection ANSYS GRANTA EDUPACK, in which different filters will be verified within the same program with the objective of selecting a material with mechanical properties similar to those mentioned above and apart from this, that can be used in the printing technique by yarn contribution, also select according to the costs and ease to get it with the aim that it can be accessible to people who require it. This is why the design of a 3D printed socket has proven to be a viable and effective solution to the lack of accessibility of low-cost customized prostheses for users who do not have the facility to obtain a complete prosthesis made of materials commonly found in the market.
