Item Impact of rubber cultivation trends on labour variation(Department of Geography, University of Kelaniya, Sri Lanka., 2020) Karunarathna, D.D.E.K; Rathnasekara, S.R.L.S.Rubber plantation has acceded the second place in out of the ways in earning foreign exchange in Sri Lanka. Rubber plantation is very important for the Sri Lankan economy as it is an industrial raw material that is used in many local Industries. The demand for rubber in the world economy was being increased day by day since the past. As a result, the production of natural rubber, as well as artificial rubber, was begun. With the induction of artificial rubber, the demand for natural rubber was rapidly decreased. The laborers in countries such as Indonesia, Thailand and Malaysia were strongly focused because of this. This situation has influenced Sri Lanka alike. Through that importing and exporting labour can be seen to rubber plantation with the introduction of new technology, special abilities in labourer’s labour, practices, the dedication of labour time changes in work can be seen as tendencies in a rubber plantation. The basic income of laborers connected to cultivation is based on industry. Because of that, it is easy to study the changes of labourer’s labour in tendencies of rubber plantation. The main objective of this experiment is to identify the new tendencies that have become an influence on the division in labour in the rubber plantation. This was done with the selected group of labourers as a sample who work affecting the Edurapola rubber state which is located in Lewala GND of Bulathkohupitiya Divisional Secretariat Division in Kegalle district. And also 30 people who do the plantation as their occupation were selected randomly from the 10% of the houses available in the same GND for the experiment by chance. The data analysis has been presented through the graphs and bars using the Excel sheet and the data gathered from the interviews and the observation have been analyzed in a relevant analytical way. Not only that but also the physical nature of the area has been described and men timed by considering the geographic information system. Data collection was done the following and wing the central methods such as questionnaires, interviews, observation and other secondary sources such as newspapers, magazines, internet, etc. Inter crops can be identified as a common tendency in a rubber plantation in the area. Due to that, there is a great division of labour in a rubber plantation.Item Contribution to rural livelihood development in Kehelbaddara cashew processing industry(Department of Geography, University of Kelaniya, Sri Lanka., 2020) Hettiarachchi, H.A.S.S.; Rathnasekara, S.R.L.S.Cashew can be described as an agro crop with high demand and prices and market value both locally and overseas. Cashew is a minor export crop and is widely cultivated in the Puttalam, Mannar, Hambanthota, Vavuniya, Anuradhapuraya, Polonnaruwa, Monaragala, Gampaha and Kurunegala in districts commonly cultivated. There are about 70,000 families in the cashew industry. The cashew production contributes in the Gampaha District 70 % to in the cashew processing industry. The main objective of this study is to investigate how the cashew processing industry has contributed to the improvement of the quality of life of the rural community. The cashew processing industry is functioning in Udugampola, Minuwangoda, Nedagamuwa, Madelgamuwa, Uggalboda, Batapotha, Makewita, Walpola, Kaluwelgoda and Thammita areas within the Minuwangoda Divisional Secretariat. The Kehelbaddara Grama Niladhari Division has been used as the study area. In data and information were obtained through questionnaires and interviews with a sample of 50 groups in the cashew processing industry in the Grama Niladhari Division. The information obtained was analyzed quantitatively and qualitatively. In rural livelihood development, the cashew processing industry can identify the major economic activity in these families. Women labor contributes much more to the process of cashew processing. Investment, technical know-how required for proper livelihood development in rural livelihood development through the cashew processing industry should be more effectively and efficiently intervened at the public and private level to promote the quality of capital resources, products and to encourage the people involved.Item Study on Human Ecological Process Affecting the Spatial Distribution of Dengue Epidemic; a Case Study on Colombo District(Reviewing International Encounters 2015, Research Center for Social Sciences, University of Kelaniya, Sri Lanka, 2015) Rathnasekara, S.R.L.S.Dengue epidemic that outbreaks in all over the world create a huge burden on those countries in relation to their population, health systems, and economies. The dengue virus was reported and serologically confirmed in Sri Lanka for the first time in 1962 and it was transmitted to humans by Aedesaegypti and Aedesalbopictus mosquitoes. The situation in Sri Lanka was changed in the end of 1980 when more than 200 DHF cases reported around Greater Colombo Area. The research problem for this study is the relationship of the human ecological processes and the related spatial distribution of dengue epidemic in Sri Lanka. Accordingly, identification of exact human ecological processes which caused the spatial distribution of dengue epidemic is the main objective of this study while identifying the factors that affect and inter-relationship between human ecology and disease ecology for spatial distribution of dengue epidemic in Sri Lanka. The research methodology was quantitative methods and data was collected through a structured questionnaire as well as interviews. Colombo district where there was the highest number of reported dengue cases in 2012, was selected as the study area, Within the Dehiwala and Padukka MOH areas were selected as regional level case study area as Dehiwela MOH area has the highest dengue cases from 2010 to 2012 and Padukka MOH areas has the least number of dengue cases in the same periods. The total population of dengue patients in three PHI areas in Dehiwela and five PHI areas in Padukka MOH area were 410 and 100 respectively. Out of these population 129 and 10 patients (age > 18) were ignored as they are not matured enough to participated this type of research. Fifty percent of the remaining population was selected as the sample for the study. The outcome of the research was that human ecological processes such as Awareness, Employment, Residencies and Living spaces, human behaviour, control measures and human Mobility has direct relationship with occurrence of dengue. Further the age and gender are also having relationship with the same. The most significant issue that was identified during the course of the study is that residencies and living space and domestic human behaviour are the main cause for occurrence of dengue in high dengue risk area and human mobility is the only process that transmits dengue to low dengue risk areas from high dengue area.Item Human Ecology of Leprosy; Medical Geographical analysis(Research Centre for Social Sciences, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Rathnasekara, S.R.L.S.; Jayasekara, I.Leprosy is one of a skin diseases that caused by a slow multiplying bacillus, Mycobacterium leprae. It can be transmitted by droplets, from the nose and mouth and it has been highly damage to the skin, the peripheral nerves, mucosa of the upper respiratory tract, and also the eyes. It can be epidemic with affect from the untreated cases of people. This research investigates what are the main human ecological factors that affect to distribute leprosy in village areas. The research approach based on the diseases ecological approach. Primary data collecting method was personal interview and secondary data collected form health institutional reports. Factor analysis and descriptive analysis method has used as a data analysis method. Matara district was the third place among the leprosy level of district in Sri Lanka, it 12% from all patients in 2014. The outcome of the research was that unawareness is the main factors that affect to distribute leprosy among the village people. Patient identification is most difficult course of the prevalence of leprosy because of village people has cultural myths behind the leprosy inflection. The most significant issue that was identified during the course of the study is that the people put out of sight this disease from the society within long period, due to that reason it can be distributed rapidly through the human host.Item Study on human ecological process affecting the spatial distribution of Dengue epidemic: a case study on Colombo district(Chulalongkorn University, Bangkok, Thailand, 2014) Rathnasekara, S.R.L.S.Item Human Ecology and Diseases Ecology: A Medico - Geographical Review(Department of Economics, University of Kelaniya, 2016) Rathnasekara, S.R.L.S.Medical Geography is one of the main approaches to study disease ecology and related issues in current Geographical Research. Disease ecology has originated from human ecology and the human ecological processes have been helpful in generating some diseases where the humans and diseases environment. It is a known fact that the every health issues are connected with human ecology and diseases ecological background. This paper examines the relationship between human ecological process and diseases ecology through a medical geography approach using secondary data.Item An Assessment of the Community Forest Management Project for Rural Development: Case Study related to Kendahena GND(Faculty of Social Sciences, University of Kelaniya, 2011) Rathnasekara, S.R.L.S.; Senarathna, S.P.
