Social Justice Innatural Resources Explosion in Vietnam Currently Looked at the Aspect of Benefits

Social justice is always a lofty goal which humanity targets at. However, for the sake of dominance, the issue of social justice is causing a wide range of challenges. Therefore, in addition to generalizing some general theoretical issues about social justice, this article raises a number of issues of social justice of the natural resources exploitation in Vietnam and the meaning of studying this issue for Vietnam's socio-economic development now. Keywords: justice, equality, benefits, natural resources DOI: 10.7176/RHSS/9-12-03 Publication date:June 30th 201

Experiments of photosynthesis assessment of phytoplankton and seaweed had been carried out in Thi Nai lagoon in rainy season (October, 2013) and dry season (May, 2014). The results showed that primary productivity of phytoplankton was 8 - 149 mgC/m3/day, and that productivity of seaweed Gracilaria verrucosa was 0.139 - 0.197 mg C/g seaweed/day. During photosynthesis process of phytoplankton, an amount of 1.42 - 1.6 tons mineral nitrogen/day and 0.14 - 0.17 tons phosphate/day was consumed in the whole lagoon. The photosynthesis process of seaweed also consumed an amount of 0.74 - 0.83 tons/day of inorganic nitrogen (including nitrate, nitrite, and ammonium), and 0.041 - 0.045 tons/day of phosphate in the whole lagoon.Các thí nghiệm đánh giá khả năng quang hợp của thực vật nổi và rong biển đã được thực hiện tại đầm Thị Nại (Bình Định) vào mùa mưa (tháng 10/2013) và mùa khô (tháng 5/2014). Kết quả nghiên cứu cho thấy năng suất sơ cấp của thực vật nổi và rong câu chỉ vàng Gracilaria verrucosa nằm trong khoảng 8 - 149 mgC/m3/ngày và khoảng 0,135 - 0,197 mgC/g rong/ngày. Trong quá trình quang hợp, thực vật nổi làm tiêu hao khoảng 1,42 - 1,6 tấn khoáng nitơ/ngày và 0,14 - 0,17 tấn phôtphat/ngày. Tương tự, quần xã rong trong đầm cũng làm tiêu hao khoảng 0,74 - 0,83 tấn/ngày các dinh dưỡng nitơ vô cơ và 0,041 - 0,045 tấn phôtphat/ngày trên toàn đầm Thị Nại

Assessment of Pollution Load into Thi Nai Lagoon, Viet Nam and Prediction to 2025

Abstract: Based on the statistical data of social-economic state and development planning to 2025 of Binh Dinh province, the pollution load from development activities has been calculated by using the environmental rapid assessment method. The results showed that development activities in Binh Dinh province create about 30.7, thousand tons of COD;17.1 thousand tons of BOD; 9.1 thousand tons of Nitrogen; 6.5 thousand tons of Phosphorous and 379 thousand tons of TSS from living activities, aquaculture, industry, farming and land leaching. Until 2025, this amount will be increased 1.4 -2.6 times. The main pollution sources are from living activities including residents and tourists and livestock farming. Therefore, treatment of waste from these sources is very necessary to minimize the waste amount discharged into the Thi Nai Lagoon

Awareness And Risk Behaviors Towards Zoonotic Disease Among Ethnic Minority In Mountainous Area Of Central Vietnam

Background: As a result of the population explosion and rapid urbanization, human activities have been causing negative impacts on the environment. The changing patterns of transmissible diseases among wild animals, livestock and human have been getting more and more complicated in the context of climate change. Ethnic community from mountainous and isolated areas undoubtedly are the most vulnerable, with the high risk of emerging and re-emerging zoonosis. Objectives: To explore the awareness and risk behaviors of the residents in Nham commune, A Luoi district towards zoonosis transmission. To determine the factors related to the risk behaviors of the residents. Methods: A sectional-cross study was conducted among 230 residents whose ages range from 18 – 85, currently living in Nham commune, A Luoi district, adjacent to the Vietnam – Laos border. All participants were interviewed directly with a questionnaire including the following categories: demographics, household wealth, awareness of zoonosis, livestock management and behaviors related to wildlife animals. Descriptive analysis and multivariable logistic regression analysis were conducted to determine factors associated with risk behaviors. Results: The proportion of respondents who have heard about zoonotic diseases was 40%. The majority of subjects raise free-range livestock (83,4%), especially on poultry and cow. The percentage of participants who consumed culled sick and dead animals accounted for 26%, over 30% of villagers slept in forest and more than 50% consumed bushmeat. Risk behaviors related to management livestock and wildlife were statistically significantly associated with gender, age of subjects, educational background, household wealth, information approach on zoonosis, and the number of livestocks. Conclusions: The proportion of respondents who have heard about zoonotic diseases was 40%. The high-risk group falls on those who consume dead domestic animals, wildlife animals and sleep in the forest. Behaviors of human-wildlife contact and zoonosis are quite common with the Nham locals, which emphasizes the necessity for intervention programs in zoonotic disease control.

Transmission of Japanese Encephalitis (JE) Virus in Gia Luong District, Ha Bac Province, Vietnam, After Je Vaccination, 1993-1994

A total of 15,183 children under 10 years old (37% of target population) was immunized with JE vaccine in Gia Luong District, Ha Bac Province, Vietnam, in 1993 to 1994. JE virus transmission was investigated by swine antibody survey and virus isolation from field mosquitoes. By the hemagglutination inhibition (HI) test, 73-90% of swine were antibody positive all year round, with high geometric mean titer (GMT) of 92.67-95.14 in May and June. By suckling mouse brain inoculation, 6 JE virus strains were isolated from Culex tritaeniorhynchus and Cx. vishuni, as well as laboratory reared F1 from field-caught Cx. tritaeniorhynchus. Serodiganosis by IgM-capture ELISA (MAC-ELISA) carried out on 60 of 85 clinical encephalitis cases detected 43 positives (71.66%). All these serologically confirmed JE cases had not been vaccinated. The results supported the vaccine efficacy to prevent overt JE
