An alarmingly high mortality and morbidity rate has been observed in COVID-19. As a new disease (similar group of SARS-CoV 2), it has been spread to more than two hundred countries and millions of people. However, COVID-19 infection is increasing in Bangladesh also. Therefore, an effective public health response is needed to control the outbreak of the mentioned new disease. If this high increasing factor turns out of control then it provides potential negative impact on social, economic, and political life of Bangladeshi people. One of the most effective ways to reduce or prevent the growth of COVID-19 is to wear masks. Many variants of COVID-19 are available in the world currently. Latest, there is a variant of omicron. This variant is too infectious. It means the vaccine seems to be not perfect against this deadliest disease COVID-19. However, people are not conscious enough about this matter generally. Nowadays, they are very reluctant to wear a mask. Their main thought is to get vaccinated and it can protect themselves. Definitely, the vaccine can protect at a certain level. However, Omicron proves that vaccine is not the ultimate solution. But, we can protect ourselves to wear a mask and keeping physical distance. This is the borderline of our research work. In this work, we proposed a system that will monitor the people who are outside the home/office via a close circuit camera. It evaluates whether the people are mask-free or not. If one does not wear a mask then an image will be captured and compared with database of national-data center for example NID server. As sensitive data, it needs security and protection. Hence, we adopt a cryptographic solution such as authenticated encryption or tag generation. As a result, receiver will be assured that a valid sender provides data to the valid receiver. The goal of this system proposal is to ensure wear face masks. As well, people will be punished based on the findings of mask-wearing. Furthermore, message authen

The Potential for Homestead Pond Polyculture of Tilapia and Carps in Coastal Bangladesh

Journal of Fisheries Science 2019年第1期1卷 15-25页

A fishers’women-led Participatory Action Research(PAR)was conducted in 30 homestead ponds to assess the potential for polyculture of Tilapia(Oreochromis niloticus)and major carps Rohu(Labeo rohita)and Catla(Catla catla)in two coastal fishing villages of *** treatments,namely T1(Tilapia 200 fish per decimal;1 decimal=40 m^2),T2(Tilapia 200+Rohu 32+Catla 8 fish per decimal)and T3(Tilapia 200+Rohu 8+Catla 32 fish per decimal),each with 5 replicates,were tried in Hossainpur and Anipara *** commercial Mega-feed was applied to the ponds twice daily at an initial rate of 10%body weight(bw)/day of Tilapia down to 4%bw/day throughout the culture *** water quality parameters of ponds including transparency,salinity and dissolved oxygen significantly varied among treatments except temperature and pH and remained within optimum range for carp polyculture except *** survival rate,harvesting weight and yield of Tilapia were significantly highest in T1(85.63±05%,258.59±18.76 g&11073±805 kg/ha,respectively)in Anipara and lowest in T3(75.63±0.37%,136.97±10.63 g&5180±406 kg/ha,respectively)in *** gross fish production was the significantly highest in T1(11354±806 kg/ha)of Anipara and lowest in T1(6325±227 kg/ha)of ***,the highest net return(866,627±84874 BDT/ha)was found in T1 of Anipara and lowest in T3(279,389±46104 BDT/ha)of Hossainpur with a significantly higher benefit-cost ratio(BCR)obtained in T1(3.26±0.20)for Tilapia and lower in T3(1.58±0.10)for polyculture Tilapia and carp of ***,it may be concluded that Tilapia production in small homestead coastal ponds has a higher potential than its mix with carps in polyculture for generating food and supplemental income opportunity for coastal fishers’women in Bangladesh.
