    Relationship between Refractive Index and Compositions of Building Windows Non Float Processed Glasses
    (Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Guruge, M. L; Edirisinghe, P. M
    Refractive index is one of the physiochemical properties of substances which is mostly used in optical sciences and provides very important information about the behavior of ray of light in various materials. This study was conducted to identify highly associated compositions of building windows non float processed glasses with refractive index and to develop a linear model to represent such relationships. Results of this study will provide a clear indication on how rays of light behave when passing through building windows non float processed glasses according to its composition. For compositions of glass, it was considered elements contained in corresponding oxide other than oxide type. A multiple linear regression model fitted for the data found that only sodium (Na), aluminum (Al), silicon (Si) and calcium (Ca) are highly associated with refractive index of building windows non float processed glasses. There was a strong positive linear relationship between refractive index and calcium (Ca) while a moderately strong negative linear relationship between refractive index and silicon (Si) for building windows’ non float processed glasses. Both sodium (Si) and aluminum (Al) had weak negative linear relationships with refractive index.

    Perceived Self-medication Practices and Associated Factors among Undergraduates of the Faculty of Humanities and Sciences (FHS), SLIIT.
    (Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Alahendra, A. M. A. A. U; Perera, O. T. S; Guruge, M. L; Anthony, D. K; Dasanayaka, C; Wijekoon, W. M. P. D. S
    This study is aimed to determine the perceived self-medication practices, associated factors, and awareness on contraindications related to self-medication among undergraduates. A random sample of 138 undergraduates of FoHS, SLIIT was selected and data were acquired from a pretested questionnaire. It was found that only 87% of the respondents had practiced self-medication in the past 3 month’s period. The presence of chronic illnesses was significantly associated with self-medication practices (p< 0.05). There was a significant association between the level of selfmedication practices and both the variety of medicines (p=0.006) and prior experience with the self-medication related side effects (p=0.05). Headache (82.9%) and common cold (44.1%) were the major health conditions for self-medication, while painkillers (83.2%) and vitamins and minerals (47.8%) were the mostly used types of medicines. Covid-19 restrictions (48.4%) and unnecessary consultation for mild illnesses (44.0%) were recognized as the major reasons for self-medication. Based on results raising awareness on self-medication by conducting educational programs in pharmaceutical aspects is recommended to improve healthy medicinal compliance among the undergraduate population.
