The objective of this study is to explore the influence of predictive maintenance technologies on operational efficiency in manufacturing startups, focusing on implementation processes, operational impacts, and the challenges encountered. This qualitative study employed semi-structured interviews to gather data from key stakeholders in manufacturing startups, including founders, operations managers, and maintenance engineers. A total of 22 participants were interviewed, with the sample size determined by theoretical saturation. The interviews were transcribed verbatim and analyzed using NVivo software. Thematic analysis was conducted to identify and categorize key themes and subthemes related to the implementation and impact of predictive maintenance technologies. The analysis revealed three main themes: Implementation Process, Operational Impact, and Challenges and Barriers. Within these themes, several categories and concepts emerged. The Implementation Process theme highlighted the importance of planning, technology selection, system integration, employee involvement, pilot testing, change management, and post-implementation review. The Operational Impact theme identified efficiency gains, predictive analytics, maintenance scheduling, resource optimization, and quality improvement as significant outcomes. The Challenges and Barriers theme underscored technological challenges, financial constraints, organizational resistance, skill gaps, data management issues, and the necessity of vendor support. The findings indicate that predictive maintenance technologies significantly enhance operational efficiency in manufacturing startups by reducing downtime, increasing productivity, and optimizing resource utilization.

Justice has always been the most basic issue and the most important ideal of man since the beginning of civilization on earth, and for this reason, humans have tried to turn it into reality. Parallel to this importance, the thinkers of every age have tried to explain the limits and gaps and realize it. Because the lack of justice in the society causes the emergence of discrimination, oppression, corruption, and the lack of public consensus, and a society based on injustice and heterogeneity emerges. As a result, in order to pass from this society and move towards a healthy society where justice is based, idealistic thoughts are created to reach the desired society. This creates schools, movements and revolutions. This process shows the importance of the fact that in the process of the evolution of civilization, human beings have always had the concern of justice in front of them and it is not limited to a specific group or nation. People everywhere and at all times have the desire to achieve justice. In this article, while examining the origin of justice in the thoughts of John Rawls and Allameh Tabatabaei, this concept was compared from the perspective of two thinkers. Rawls from the contemporary West and Allameh Tabatabaei from contemporary Islam are among the most prominent philosophers and thinkers in the world who look at the concept of justice with different intellectual bases. But their theoretical output has similarities in the field of the concept of justice. In this article, using the hermeneutic recovery method, the challenges in the thoughts of Rawls and Allameh Tabatabaei in the field of justice were investigated.
