    Impact of global smoking prevalence on mortality: a study across income groups
    (Springer link, 2024-07-04) De Silva, R; Silva, D; Piumika, L; Abeysekera, I; Jayathilaka, R; Rajamanthri, L; Wickramaarachchi, C
    Background Smoking significantly contributes to the mortality rates worldwide, particularly in non-communicable and preventable diseases such as cardiovascular ailments, respiratory conditions, stroke, and lung cancer. This study aims to analyse the impact of smoking on global deaths, and its association with mortality across the main income groups. Methods The comprehensive analysis spans 199 countries and territories from 1990 to 2019. The study categorises countries into four income groups: high income, upper middle income, lower middle income, and low income. Results The findings underscore the profound impact of global tobacco smoking on mortality. Notably, cardiovascular disease mortality is notably affected in both upper-middle-income and high-income groups. Chronic respiratory disease mortality rates show a significant impact across all income groups. Moreover, stroke-related mortality is observed in the lower-middle, upper-middle, and high-income groups. These results highlight the pervasive influence of smoking prevalence on global mortality, affecting individuals across various socioeconomic levels. Conclusion The study underscores the critical implications of smoking on mortality rates, particularly in high-income countries. It emphasises the urgency of targeted interventions in these regions to address the specific challenges posed by tobacco smoking on public health. Policy recommendations include implementing prohibitive measures extending to indoor public areas such as workplaces and public transportation services. Furthermore, allocating funds for research on tobacco and health, is imperative to ensure policymakers are consistently informed about emerging facts and trends in this complex domain.

    Timely_Tech: IoT based Motion, Health, and Fitness Monitoring System for Laborers in Indoor and Outdoor Environments
    (IEEE, 2022-07-18) Yatagama, H.C; Anuruddika, W.G.S.J; Ranasinghe, P. T. K; Jayasekara, P.D.G.T; De Silva, D; Wijendra, D
    Smart wearables collect and securitize data, and in some cases, make intelligent decisions and respond to the user. "IOT based motion, health and fitness monitoring system for laborers in indoor and outdoor environments" is a concept that has been developed in order to ensure the safety of employees in their working environments. The key objective is to provide the employees with a SMART device that can monitor many of their vital bodily functionalities such as the pulse rate, oxygen in blood concentration and body temperature and thereby rectifying any potential risk or danger to any significant employee. Monitoring the motion of the limbs of each individual employee and analyzing the postural changes, degree of motion and thereby constantly keeping in track about the movements of employees is another major functionality that is proposed to be discussed under the research paper. Gaseous concentration around the working area has been another major aspect that have been taken into consideration through this study, toxic gas content levels according to the age limits that will affect each individual has been taken into note when developing the afore mentioned wearable device. Monitoring the location of the employees both online and offline will be much more convenient to track the working areas of each individual and also it will also be a great support if a certain employee faces any kind of accidental situation. Similarly, locating the working areas of a certain individual when they are offline is a novel concept has been developed in order to obtain the step count utilizing the aid of the motion detection algorithm.

    The Impact of Loyalty Value on Purchase Intention: Comparative Analysis of Healthy Food and Unhealthy Food Advertisements in Sri Lanka
    (2020-05) Dissanayake, D. M. N. I; Seneviratne, N. T; Hansasara, L. A. D. S; Perera, L. D. N; Jayasuriya, N. A
    The purpose of the study is to seek the impact of loyalty on purchase intention of consumers with regard to healthy and unhealthy food advertisements in Sri Lanka. After referring to various past researches it has been identified that loyalty is one of the most influential factors in determining the purchase intention of consumers. However, when referring to past researches it has been evident that there is a lack of knowledge in the area of healthy and unhealthy food advertisements particularly in Sri Lankan context. Due to the shortfall of literature the present study concentrated on exploring the impact of loyalty towards the purchase intention of Sri Lankan consumers. Therefore, the objectives of the study were primarily achieved by analysing the data gathered via a selfadministered questionnaire that was distributed among 384 Sri Lankan consumers. Convenient sampling was the sampling method that was utilized and analytical techniques such as correlation and regression were applied. The present study indicated that loyalty has a positive impact towards purchase intention of Sri Lankan consumers when it comes to both healthy and unhealthy food advertisements. When it comes to the knowledge implications, the study is significant as it identified that that there is a strong correlation existing between the loyalty and purchase intention. It has also been apparent that brand loyalty is created through a past positive experience that a consumer has with a particular food brand.
