Optimal and safe site selection for the Municipal Solid Waste (MSW) Management : using GIS and Analytic Hierarchy Process (AHP)

Ananda Karunarathne 서울대학교 국토문제연구소 2017 地理學論叢 Vol.64 No.-

Municipal solid waste (MSW) management is possible to be identified as one of the mostly cited fields in the optimization applications. This is because optimization of solid waste management is most general in contemporary research applications as the issue is being becoming more complex and impasse with rapidly increasing of urban population particularly in the developing world. Optimal site selection is to be identified as one of the famous facility location problems in the discipline of location science. With a range of growing impediments, such as scarcity of suitable lands for dumping, increasing of transportation and labour costs, diversifying of environmental pollutions etc, the application of optimization approaches on municipal solid waste management has been very famous among scholars and policy planners. The city of Colombo is a famous rapidly growing and propelling city in the South Asia. This is because many forms of internal migration flows can be seen into the city of Colombo. On this background, daily tonnage of solid waste accumulation has been augmented exponentially. At present, the issue has been become one of the burning dilemmas in the city. In this context, the purpose of this paper is to identify the potential, optimal and safe sites for SMW management in the city of Colombo by using GIS and Analytic Hierarchy Process (AHP). The study used mainly five criteria (Inhabited and build-up areas, Slopes, Elevation, Water bodies, and Road categories) and different constraints for each of them in terms of the optimal and safe site selection mechanism. The AHP approach is applied in order to obtain acute factor scoring and weighting scheme. Finally, the study used Weighted Overlay method in ArcGIS 10.2 environment for the optimal and safe site selection. The analyses of the results are revealed that six vacant sites are available and they are potentials to be used as optimal and safe sites for the MSW management practices. The study suggests that the preliminary sites investigations are needed to be done in order to clarify the ownerships and land valuation in advance.

Social Policy Legacies and the Contemporary Development Trajectory of Sri Lanka

Ananda Karunarathna,Edo Andriesse 한국외국어대학교 인도연구소 2018 남아시아연구 Vol.24 No.1

Sri Lanka is one of the lower-middle income countries in the South Asian region, yet it has simultaneously experienced ‘High Human Development’. This is all the more remarkable given the 1983-2009 civil war. This paper has two objectives. First, it reviews the reasons for Sri Lanka’s considerable human development achievements while still being a low middle income country by synthesizing the existing body of literature on Sri Lanka’s socioeconomic development. Second, it provides an assessment of contemporary human developments. How has Sri Lanka fared in the last two decades? We pay special attention to the country’s health and education policies. Based on a review of secondary sources we conclude that since the end of the civil war, Sri Lanka has experienced a substantial peace dividend. The task for Sri Lanka is to build on this peace dividend, to provide employment in the northern and eastern areas as well as to foster inclusive development throughout the country. The fact that Sri Lanka is classified as a high-human development should be no reason for complacency, given the remaining socio-economic and socio-spatial challenges. Promising industries are medical tourism, maritime logistics and agri-business.

Foreign Interventions in the Sri Lankan Civil War: Implications for Internal Socio-economic and Geopolitical Issues

Ananda Karunarathna Y.,Manawadu, L. 한국외국어대학교 인도연구소 2018 남아시아연구 Vol.24 No.3

Sri Lanka is one of the South Asian developing countries which experiencing a spectrum of socio-political and economic changes after the end of thirty years of civil war in 2009. During the war period approximately from 1983 to 2009, the country has had to face a range of influences from the outside actors as a developing country in terms of offensive and defensive interventions. With heightened the magnitude of consequences of interventions, the country experienced variegated impediments in plenty particularly in her development trajectory. Despite the facts that, on the other hand, the country had been received some of genuine assistants from many allies in terms of peace building. In this context, the objective of this work was to examine the foreign interventions in the Sri Lankan civil war in terms of internal socioeconomic and geopolitical predicaments. The geopolitical maps were prepared in ArcGIS 10.3 environment. The examined insights and ideologies were revealed that the foreign offensive interventions in which directly or indirectly linked with the peace processes have been made counterproductive consequences on her both the socio-economic and geopolitical context adversely. And also, some of the acts had helped to lengthen the civil war, on the one hand making it impasse in the peace negotiation process and on the other hand making the terrorists’ military prowess strong which affected the north-south livelihood and the economy continues unabated. The contemporary development trajectory of the country has been experiencing some of emerging trends with the equilibrium of considerable human development level. As a potential ally, current geopolitical role and geopolitical-codes of India is very crucial and important in the Sri Lankan development trajectory.

Dietary Zinc and Prostate Cancer in the TRAMP Mouse Model

Circumstantial evidence indicates that zinc may have an important role in the prostate. Total zinc levels in the prostate are 10 times higher than in other soft tissues. Zinc concentrations in prostate epithethial cancer cells are decreased significantly. Zinc supplementation for prevention and treatment of prostate cancer in humans has yielded controversial results. No studies have been reported in animal models to show the effect of zinc supplementation on prevention of prostate cancer, thus far. In this study, we have examined the effect of zinc supplementation on development of prostate cancer in a TRAMP mouse model. Results from our study indicate that dietary zinc plays an important role in prostate carcinogenesis. Tumor weights were significantly higher when the dietary zinc intake was either deficient or high in comparison to normal zinc intake level, suggesting that an optimal dietary zinc intake may play a protective role against prostate cancer. Further, our studies also showed decreased insulin-like growth factor (IGF)-1 and IGF-1/IGF binding protein-3 ratio in normal zinc-supplemented animals, suggesting that zinc may modulate IGF-1 metabolism in relation to carcinogenesis. We conclude that optimal prostate zinc concentration has a protective role against cancer.

Changing Industrial Structure and their spatial distribution of Sri Lanka : An Economic Geographical perspective

At present, most of economists and also experts have being made their extra ordinary attention on the theme of development of developing countries. Most of developing countries are now experiencing many kinds of changes in their economies. However, the problem is meanwhile they have to face other impediments in plenty which are belonged to their underdevelopment status. Sri Lanka is as a South Asian developing country has unique changes in its economic structure particularly after the introduction of open economy system in 1977. Based on the British colonial establishments, the country’s main exports are agriculture products. However, after the open economy system, the secondary export earnings have been proliferated. Particularly, garment productions made predominant contribution to the export sector. For an instance, since 1950 to 2014, the industry sector has been increased from 19.6% to 32.3% while agriculture sector has been declined from 46.3% to 10.1%. In these circumstances, the garment sector acted as the centripetal force to create hundreds of thousands job opportunities particularly in rural areas. Meanwhile, the thirty years of civil war made an irreparable lost to the country in both the physical and human properties. After end of the war in 2009, the country has a big gaining momentum to proliferate her economy with rejuvenation by considering the existing ‘demographic dividend’ and ‘peace dividend’ as windfalls of success.

Ananda S. Amarasekara,Lauren J. Leday,Deping Wang,Cristian D. Gutierrez Reyes 한국고분자학회 2023 Macromolecular Research Vol.31 No.10

Sodium levulinate cellulose (SLC) was prepared as a new longer carbon chain analog for carboxymethyl cellulose (CMC) in 66–94% yield using the Williamson ether synthesis reaction between sodium hydroxide treated cellulose and brominated levulinic acid in aqueous iso-propanol medium under thermal and microwave conditions. Levulinate cellulose ether produced was characterized by FT-IR, TG–DTA, X-ray and proton NMR. The thermal reactions carried out at 90 °C for 3 and 24 h gave SLC products with degrees of substitutions of 0.48 and 0.86, respectively, whereas the microwave synthesis product showed a degree of substitution of 0.32 as determined by ASTM D1439-03 method used for CMC.

Distributed Ledger Technology (DLT) refers to a process and related technologies that enable a person to safely suggest, verify, and record state changes (usually updates) to synchronize ledgers distributed across network nodes. DLTs are becoming increasingly important as data management requirements evolve. Therefore, they need to understand the current state of standards (such as distributed storage and access technologies) to address future requirements. This paper provides ITU-T FG-DLT standard activities, such as standardization ization trends, use cases, reference architectures, platform evaluation criteria and future prospects.
