Item type: Item , Television marketing of food and non-alcoholic beverages (FNAB) high in fats to children in Sri Lanka(University of Colombo, 2022) Samarakoon, S.M.D.R.; Thoradeniya, S.T.; Arambepola, C.; De Zoysa, P.; Wickramasinghe, V.P.; Piyasena, B.G.W.W.P.; Abeysinghe, H.; Senevirathne, A.N.Y.Introduction: Dietary fat exerts a significant risk of coronary heart disease (CHD) and obesity, which is on the rise in children. Television marketing of food and non-alcoholic beverages (FNAB) influences the dietary choices of children. There is a global interest in reducing fat, particularly trans-fat, contents in food and in regulating unhealthy FNAB marketing to children. This study aimed to explore the extent of the television marketing of FNAB high in fat, to which Sri Lankan children are potentially exposed. Methods: The analysis was on FNAB products advertised over 33 hours on the three most popular television channels for children aged 4-16 years in Sri Lanka.The International Network for Food and Obesity/NCDs Research, Monitoring and Action Support (INFORMAS) Network Protocol was used, and the food products were categorised as ‘permitted’ or ‘non permitted' based on their fat content according to the WHO-South-East Asia Region (SEARO)-Nutrient Profile Model (NPM).Item type: Item , Cardiovascular response to isometric handgrip in healthy long-term meditators: a comparative study(University of Colombo, 2022) Karunarathne, L.J.U.; Fernando, A.D.A.; Amarasiri, W.D.A.L.Introduction: Effects of meditation on the cardiovascular system are mediated through the autonomic nervous system. Meditators are thought to have lower sympathetic activity. We evaluated cardiovascular response to isometric handgrip test (IHG) in healthy long-term meditators (LTMs) and non-meditators. Methods: This cross-sectional comparative study compared 18 healthy LTMs practising Buddhist meditation consistently >3 years, selected by a validated intake interview, with 18 age-sex matched healthy non-meditators, selected through purposive sampling as controls. Participants performed IHG at 30% of maximal voluntary contraction for three minutes with MLT004/ST Grip Force Transducer and Power Lab 4/26 (AD Instruments) in the supine position. Non-dominant arm systolic blood pressure (SBP) and diastolic blood pressure (DBP) was measured in the last 15 seconds of every minute, two minutes before, after and during IHG by a calibrated automated BP metre. The differences of parameters between the highest BP during IHG and at baseline were taken as the measure of response. Mann-Whitney U test assessed between-group comparisons.Item type: Item , Hyperechoic amniotic fluid in a term pregnancy(Wolters Kluwer, 2018) Kaluarachchi, A.; Jayawardena, U.G.P.; Probhodana Ranaweera, A.K.; Rishard, M.R.M.The presence of highly echogenic amniotic fluid (AF) is uncommon, and presence creates a dilemma in the mind of the clinician. Echogenic AF has been attributed to meconium, blood, and vernix caseosa. Many studies have shown that the presence of meconium is unlikely in most cases. We report a case of highly echogenic AF detected at 37 weeks which was managed conservatively with careful fetal monitoring for further 2 weeks expecting spontaneous onset of labor. Labor was induced due to reduced fetal movements at 39 weeks. Healthy baby weighing 3130 g was delivered by cesarean section after a failed induction with prostaglandin.Item type: Item , Evaluating the Socio-Economic Impact of Cultural Tourism Development in Anuradhapura District(Department of Archaeology, University of Kelaniya, 2025) Sawjanya, S.; Nuskiya, M.H.F; Ruzaik, Fareena; Ameer, M.L.FTourism is a significant global economic sector, contributing approximately 10% to global GDP. This study examines the socio-economic potential of cultural tourism development in the Anuradhapura District, a UNESCO World Heritage site renowned for its rich Buddhist heritage and cultural significance. The research aims to evaluate the socio-economic impacts of cultural tourism development on local communities in Anuradhapura District and identify the factors influencing sustainable tourism development. Data were collected from 120 respondents using a structured questionnaire, and statistical analyses were conducted using SPSS. Descriptive statistics revealed that respondents' demographic characteristics, including age, gender, education, and DS division, significantly influenced perceptions of cultural tourism's impact. Pearson correlation analysis showed perfect positive relationships (r = 1.000, p < 0.01) between cultural tourism development and variables such as personal income increase, business growth, infrastructure development, and service improvement. A moderate positive correlation (r = 0.530, p < 0.01) was found between tourism development and involvement in decision-making, while a weak positive correlation (r = 0.231, p < 0.01) was observed for job opportunities. Multiple regression analysis highlighted that the perception of benefit distribution in the community (β = 0.942, p < 0.01) and involvement in planning decisions (β = 0.530, p < 0.01) had strong positive impacts on cultural tourism development. Other variables, such as personal income increase, heritage preservation, and quality of life improvement, also showed statistically significant contributions. The findings are consistent with previous tourism studies highlighting the role of cultural tourism in promoting sustainable socio-economic development and heritage conservation.Item type: Item , චරක සංහිතාවේ අන්තර්ගත අනිත්ය, අනාත්ම හා ක්ෂණභංගූරවාදය පිළිබඳ විශ්ලේෂණාත්මක අධ්යයනයක්(The Royal Asiatic Society of Sri Lanka, 2019) Molligoda, S.P.; Somarathna, K.I.W.K.චරක සංහිතාව යනු ආයුර්වේදය පිළිබඳව රචිත ප්රධාන ග්රන්ථත්රය වන ‘වෘහත්ත්රයී’ අතුරින් ප්රධාන චිකිත්සා ග්රන්ථයයි. ආයුර්වේද ඥාන සාධනයෙහි ලා අතිශයින්ම අවශ්ය වන උපදෙස් වලින් හෙබි චරකය ඊට පසුව ලියවුනු සියලු සංග්රහයන්ට ගුරු වී තිබෙනු දැකිය හැකිය. අග්නිවේශ තන්ත්රයේ ප්රතිසංස්කරණයක් සේ සැළකෙන චරක සංහිතාව ප්රතිසංස්කරණය කරන ලද්දේ කාශ්මීරයේ විසූ චරක නම් වූ සෘෂිවරයාය. ඔහු බෞද්ධ මහායානික භික්ෂුවක් බව ප්රචලිතය. එසේම එතුමා ක්රි.ව. දෙවන හෝ තුන්වන සියවසේ ජීවත් වන්නට ඇතැයි අනුමාන කෙරේ. බෞද්ධ දර්ශනයේ මූලික හරය අනිත්ය හා අනාත්මයයි. යමක් විශ්වය පුරා පැතිර පවතීද, යමක් එක් සිරුරක් හැර අනෙක් සිරුරක් අල්ලා ගනී ද , යමක් මෙලොව විෂය රස වළදයි ද , යම් හෙයකින් යමෙකුගේ නිරතුරු පැවැත්මක් ඇද්ද එහෙයින් එය ආත්මය කියැයි කියනු ලැබේ.
