Women’s Potential in Dealing with Natural Disasters : A Case Study from Sri Lanka
JAYARATHNE, Saranga Subhashini 이화여자대학교 아시아여성학센터 2014 Asian Journal of Women's Studies(AJWS) Vol.20 No.1
Disaster is gender indifferent but its impact is usually gender differentiated. The 2004 Tsunami statistics show that male survivors in Sri Lanka outnumbered female survivors. The notion of women being the “weaker sex” gives them limited space for learning physical skills that are deemed vital for surviving disasters. Their knowledge and experience regarding the environment is always undermined. This further limits and discourages them from contributing towards disaster management. Women should be incorporated at every level in the disaster management cycle. Women-centered public awareness and skills training can help increase women and children’s disaster preparedness and equip them with the skills necessary to overcome disasters. Women’s participation in national-level decision-making is also a necessity. A gender-blind disaster management system can only worsen the impact of disasters, especially for women and girls. This paper challenges the depiction of women as mere victims of disasters, while attempting to point out the vital nexus between women’s untapped potential and disaster management.

Anti-Inflammatory and Anti-Obesity Properties of Food Bioactive Components
Shasika Jayarathne,Iurii Koboziev,Oak-Hee Park,Wilna Oldewage-Theron,Chwan-Li Shen,Naima Moustaid-Moussa 한국식품영양과학회 2017 Preventive Nutrition and Food Science Vol.22 No.4
Obesity is an epidemic and costly disease affecting 13% of the adult population worldwide. Obesity is associated with adipose tissue hypertrophy and hyperplasia, as well as pathologic endocrine alterations of adipose tissue including local and chronic systemic low-grade inflammation. Moreover, this inflammation is a risk factor for both metabolic syndrome (MetS) and insulin resistance. Basic and clinical studies demonstrate that foods containing bioactive compounds are capable of preventing both obesity and adipose tissue inflammation, improving obesity-associated MetS in human subjects and animal models of obesity. In this review, we discuss the anti-obesity and anti-inflammatory protective effects of some bioactive polyphenols of plant origin and omega-3 polyunsaturated fatty acids, available for the customers worldwide from commonly used foods and/or as components of commercial food supplements. We review how these bioactive compounds modulate cell signaling including through the nuclear factor-κB, adenosine monophosphate-activated protein kinase, mitogen-activated protein kinase, toll-like receptors, and G-protein coupled receptor 120 intracellular signaling pathways and improve the balance of pro- and anti-inflammatory mediators secreted by adipose tissue and subsequently lower systemic inflammation and risk for metabolic diseases.

Vision-based Leader-Follower Mobile Robots for Cooperative Object Handling
D.U. Jayarathne,H.A.K.R. Vidumal,S.M.A.Senevirathne,P.G. Jayasekara,T.D.Lalitharatne 제어로봇시스템학회 2019 제어로봇시스템학회 국제학술대회 논문집 Vol.2019 No.10
This paper has addressed the problem of transporting a long object from a given starting location to an end location using leader-follower robot formation in an environment filled with obstacles. Only the leader robot has the authority to make decisions. It possesses the main controller and is capable of navigating through an unknown environment using the data provided by on-board sensors. In the proposed system, a vision-based feedback method is combined with an explicit control method that oversights the virtual trailer between the leader and the follower. The parameters required to maintain a constant distance between the two robots are computed by the leader and transmitted to the follower directly. A fiducial marker is mounted on the front of the follower robot and is captured by a camera attached to the leader robot. Information exchanging methods based only on impedance control can be expensive because of the need of high-level controllers and force/torque sensors for both robots. Furthermore, the visual response scheme adds robustness to the system by reducing the limitations of sole explicit control methods. The proposed control algorithm is implemented on the developed mobile robots. The experimental results suggest that the vision-based feedback method is more effective in cooperate object carrying tasks.
