This paper seeks to describe the process by which a database-centric web application was redesigned and rewritten to take advantage of Apache’s Lucene - an open-source information retrieval software library written in the Java programming language. After the implementation of a Lucene-based text index of “semi-structured data”, a college radio station's card catalog application was able to deliver higher-quality search results in significantly less time than it was able to do using just a relational database alone. Additionally, the dramatic improvements in speed and performance even allowed the search results interface to be redesigned and enhanced with an improved pagination system and new features such as faceted search/filtering.

En el presente estudio se propone el diseño de un sistema de SST para reducir los riesgos laborales en la empresa Casa Blanca SRL. Para ello, se diagnosticó la situación actual de toda la empresa, en el que se identificó un total de 200 días por ausentismo del personal durante el periodo 2019-2021 a causa de accidentes laborales, generando costos directos de S/ 23 275, así como el cumplimiento de solo el 11% en relación a los requisitos de la Ley 29783 y por medio de la matriz Ishikawa se determinó las causales de mano de obra, medio, método y maquinaria. Luego, a través de la Matriz IPER se identificaron un total de 14 riesgos en las actividades de la empresa, de los cuales el 79 % son del tipo moderado y el 21 % son altos. Posteriormente, para el diseño del sistema de SST se terminaron los controles operacionales para las causales antes mencionadas, midiendo el impacto por medio de una matriz IPERC, obteniendo la reducción de riesgos a 86% tolerables y 14% a moderados. Para el diseño de sistema propuesto se tomó en cuenta los documentos y registros obligatorios que establece la ley 29783, proyectándose al cumplimiento de los requisitos en un 86%. Finalmente, con la evaluación económica, se demostró la viabilidad de la propuesta de diseño, obteniendo un VAN de S/ 37 265, TIR de 88% y un B/C de 1,61. / In the present study, the design of an OSH system is proposed to reduce occupational risks in the company Casa Blanca SRL. For this, the current situation of the entire company was diagnosed, in which a total of 200 days due to staff absenteeism during the 2019-2021 period due to work accidents were identified, generating direct costs of S/ 23,275, as well as compliance of only 11% in relation to the requirements of Law 29783 and through the Ishikawa matrix, the causes of labor, means, method and machinery were determined. Then, through the IPER Matrix, a total of 14 risks were identified in the company's activities, of which 79% are of the moderate type and 21% are high. Subsequently, for the design of the SST system, the operational controls for the aforementioned causes were completed, measuring the impact through an IPERC matrix, obtaining a risk reduction of 86% tolerable and 14% moderate. For the proposed system design, the mandatory documents and records established by Law 29783 were taken into account, projecting 86% of the requirements to be met. Finally, with the economic evaluation, the feasibility of the design proposal was demonstrated, obtaining a NPV of S/ 36,436, an IRR of 96% and a B/C of 1.66.
