Item Applicability of virtual billing on smartphone based applications for paper waste reduction.(International Research Symposium on Pure and Applied Sciences, 2017 Faculty of Science, University of Kelaniya, Sri Lanka., 2017) Dissanayake, C.; Peiris, P.; Senevirathne, D.; Wijesooriya, K.; Rupasinghe, T. D.; Liyanaarachchi, N.The reception of a printed bill has been in global use as the proof of a transaction. Originating as a handwritten bill, the transaction billing has evolved with the advent of printers and computers, and are now an indispensable part of Point – of – Sales systems (POS). However, with the rapid expansion of business entities as well as the increase of wants of consumers, conventional billing consumes large volumes of paper, even in an organizational basis. Most of the bills generated as such are immediately disposed after an initial inspection. Hence, the paper used for billing has a very short usable lifespan and the paper along with the ink become waste. With the rapid advent of the smartphone providing an internet connected handheld portable computational device for the public, proposition of an internet-based virtual billing system has become timely. Although previous studies have been carried out on implementing virtual billing systems, the potential of smartphone has not been utilized in the practical implementation of such systems. The overarching goal of this study is to reduce reliance on paper for billing work. This outcome of the study aims to develop a virtual or a paperless billing system, with interfaces for the storefront user and consumer user. This virtual bill will directly appear on the smartphone application, which uses an Android operating system. In addition to the reduction of paper usage, this approach will also help the customers keep track on the expenditure for a certain commodity per vendor over a particular time period without manually having to calculate the expenses. The outcomes of this research will evaluate the feasibility of practically implementing such a paperless billing system in the context of Sri Lankan business entities.Item A study on medico legally significant blunt thoracic trauma.(Institute of Medico-legal Publications, 2023) Gunathilaka, M.M.A.C.; Kitulwatte, I.D.G.; Wijewardena, H.; Gunathilaka, K.M.T.B; Dissanayake, C.; Jayathilake, R.; Wijeratne, P.INTRODUCTION: Thoracic trauma (TT) accounts for significant mortality and morbidity. Blunt thoracic trauma is reported more frequently than sharp force trauma, where motor traffic collisions account for the majority. Addressing medico-legal issues is often a challenge in TT. The purpose of this study was to evaluate blunt chest trauma from a medico-legal point of view. METHODS: A retrospective descriptive study was conducted based on case records of the victims (living and dead) of TT over three years presented to a Teaching Hospital and a District General Hospital in Western Province. RESULTS: There were 248 living patients and 195 deceased. Road accidents accounted for TT in 236 (53.3%), followed by 166 (37.5%) assaults. Out of the deceased, 89% had a very short survival period. “Multiple chest injuries” was the cause of death in 83 (42.5%) dead, and 91 (46.7%) died due to TT. Road accidents accounted for N=71 (78% of deaths due to TT). Out of the live patients, 87 (35.8%) had grievous or above-category injuries to the chest, and victims of assault were commonly having non-grievous injuries with a significant association (p<0.001). A total of 175 (39.5%) had rib fractures, and 125 were following motor traffic accidents. CONCLUSIONS: Blunt TT accounts for significant mortality and morbidity, with the most common circumstances being road accidents. Most of them come under a severe category of hurt with a short survival period among the dead.Item Sustainable use of Cryptocoryne wendtii and Echinodorus cordifolius in the aquaculture industry of Sri Lanka by micropropagation(Sri Lanka Association for Fisheries and Aquatic Resources, 2007) Dissanayake, C.; Hettiarachchi, M.; Iqbal, M.C.M.Item
