BackgroundSurgical site infections (SSIs) are a global concern affecting patient recovery, prolonging hospital stay and raising healthcare costs.AimTo address this, a structured training module was implemented to enhance the efficacy of surgical painting and draping among the interns, reducing SSI risk.MethodsA questionnaire was distributed to 194 interns, covering fundamental inquiries on SSIs, aseptic practices and an assessment of the participant's knowledge regarding preoperative skin preparation and draping. Students then attended lectures, demonstrations, hands-on sessions and an operating room workshop dedicated to surgical painting and draping techniques. Proficiency was evaluated through a follow-up questionnaire.ResultsThere was a significant increase in the percentage of good score from 27.6% to 86.9%. A comparative analysis of surgical site infection (SSI) rates at our institution was performed before and after integrating a cohort of trained clinicians.ConclusionAlthough a significant reduction in SSI rates was observed, it cannot be definitively attributed solely to the introduction of the trained personnel. Nonetheless, the findings underscore the potential impact of rigorous training in aseptic techniques on reducing SSI incidence.

Advancing Sustainability in Software Engineering

Author: Kalpana, V. ; Balapriya, S. ; Anish, T. P. ; Yamini, B. ; Venkateshan, A. ; Anusha, S. ; Nithyanandhan, R.

The escalating environmental consequences of software development have raised a concern for sustainable software engineering throughout the life cycle. Green software engineering aims at reducing the power utilization in software systems as well as containing the carbon impact of software systems, and managing the resources properly. This survey also summarizes the major approaches to integrate sustainability into each phase the following phases are sustainable requirements engineering, energy-aware coding, green DevOps, and sustainable data management. Sustainability is further improved by ideas such as energy efficient design patterns, resource efficient algorithms, and dynamic resource scaling. It also covers some of the recent tools for energy profiling, green deployment and green cloud computing. The goal of this paper is to give some idea of the state of sustainable software engineering practices, potential future developments, and to point out where research, automation, and policy may be needed to promote the adoption of such practices.

Experimental Study of Isopropyl Acetate and Acetone Additive Gasoline on a Spark-Ignition Engine and its Impact on Green Environment

Author: Parthipan, J. ; Jayaprabakar, J. ; Neupane, Gaurab ; Anbazhaghan, N. ; Lakshmanan, T.

Background::Gasoline engines using alcohol fuels are being researched in the present trend since they are seen to be viable as diesel engines. The effect of isopropyl acetate and acetone additive blends on gasoline is explored in this study using a single-cylinder four-stroke gasoline engine operating at a constant speed of 2500 rpm under all loading conditions.Methods:Two gasoline blends are prepared by adding 5% and 10% by volume of isopropyl acetate and acetone separately. Properties are investigated and tested for its engine performance and emission.Results:The trial results demonstrated that the A5 (5% Acetone + 95% Gasoline) brake thermal efficiency improved when compared to pure gasoline. At maximum engine load, all additive blends have lower brake specific fuel consumption than pure gasoline. However, under full load, the emissions of various additive blends are lower than those of pure gasoline.Conclusión:Results revealed that IA5 (5% Isopropyl acetate + 95% Gasoline), IA10 (10% Isopropyl acetate + 90% Gasoline), and A10 (10% Acetone + 90% Gasoline) are considered good for decreasing HC, NOx, and CO emissions respectively. The findings of this study can be considered as a patent to lay the information on these types of alcohols in gasoline engines.
