Socio-demographic associates of perceived social support among crop farmers in Ido local government area, Ibadan, Nigeria

This study was designed to assess perceived social support (PSS) and the socio-demographic characteristics associated with same among crop farmers in Ido LGA of Oyo State, Nigeria. The design is a farmer-targeted cross-sectional survey. Primary data were collected among 215 randomly selected respondents using structured questionnaire, which were administered via structured interview. Cross-tabulation and chi-square were used to show distributions and significance of associations between pairs of socio-demographic characteristics and levels of perceived social support. Contingency co-efficient was used to assess the extent of significant associations. Results indicated that high, moderate and marginal levels of social support were enjoyed by 40.9%, 30.7% and 28.4% of respondents, respectively. Sex and age were significantly associated with levels of social support (p < 0.05) but marital status and education were not (p > 0.05). Being female and being of decreased age are significantly associated with benefiting higher level of social support. Marital status and education are inconsequential factors in accruing social support among farmers in the study area. Social support is fairly palpable among farmers, but deliberate efforts to instigate its manifestation will open farmers to reaping the enormous advantages that social support offers.

Environmental shocks and agricultural revenue: Secondary data analysis of 2018/19 Nigerian general household survey

The study was designed to investigate the link between environmental shocks and agricultural revenue using secondary data obtained from the 2018/2019 Nigerian general household survey. Variables were subjected to correlational analysis using Spearman correlation coefficient. Results indicate that 0.8% and 6.6% of Nigerian households experienced harvest destruction by fire and flooding respectively. The average amount of money accrued from the sale of unprocessed and processed crops in Nigeria were <strike>N</strike>112,774 and <strike>N</strike>44,593 respectively. Destruction of harvest by fire is negatively but insignificantly related to mean total sales of  unprocessed crops (r = -.268, p > 0.05) while it is negatively, strongly and significantly related to mean total sales of processed crops (r = -.996, p < 0.05). Flooding that caused harvest failure is negatively but insignificantly related to mean total sales of unprocessed crops (r = -.217, p > 0.05) and processed crops (r = -.300, p > 0.05). Destruction of harvest by fire is the single most vital determinant of reduced earnings from sales of processed crops. Empirical credence afforded the idea that environmental shocks and agricultural revenue are conflicting social realities in Nigeria.

Assessing the benefits of five years of different approaches to treatment of urogenital schistosomiasis: A SCORE project in Northern Mozambique.

BACKGROUND: In Mozambique, schistosomiasis is highly endemic across the whole country. The Schistosomiasis Consortium for Operational Research and Evaluation (SCORE) coordinates a five-year study that has been implemented in various African countries, including Mozambique. The overall goal of SCORE was to better understand how to best apply preventive chemotherapy with praziquantel (PZQ) for schistosomiasis control by evaluating the impact of alternative treatment approaches. METHODS: This was a cluster-randomised trial that compared the impact of different treatment strategies in study areas with prevalence among school children of ≥21% S. haematobium infection by urine dipstick. Each village was randomly allocated to one of six possible combinations of community-wide treatment (CWT), school-based treatment (SBT), and/or drug holidays over a period of four years, followed by final data collection in the fifth year. The most intense intervention arm involved four years of CWT, while the least intensive arm involved two years of SBT followed by two consecutive years of PZQ holiday. Each study arm included 25 villages randomly assigned to one of the six treatment arms. The primary outcome of interest was change in prevalence and intensity of S. haematobium among 100 children aged 9-to-12-years that were sampled each year in every village. In addition to children aged 9-to-12 years, 100 children aged 5-8 years in their first-year of school and 50 adults (aged 20-55 years) were tested in the first and final fifth year of the study. Prevalence and intensity of S. haematobium infection was evaluated by two filtrations, each of 10mL, from a single urine specimen. PRINCIPAL FINDINGS: In total, data was collected from 81,167 individuals across 149 villages in ten districts of Cabo Delgado province, Northern Mozambique. Overall PZQ treatment resulted in a significant reduction in the prevalence of S. haematobium infection from Year 1 to Year 5, where the average prevalence went from 60.5% to 38.8%, across all age groups and treatment arms. The proportion of those heavily infected also reduced from 17.6% to 11.9% over five years. There was a significantly higher likelihood of males being infected than females at baseline, but no significant difference between the sexes in their response to treatment. The only significant response based on a study arm was seen in both the 9-to-12-year-old and first-year cross sections, where two consecutive treatment holidays resulted in a significantly higher final prevalence of S. haematobium than no treatment holidays. When the arms were grouped together, four rounds of treatment (regardless of whether it was CWT or SBT), however, did result in a significantly greater reduction in S. haematobium prevalence than two rounds of treatment (i.e. with two intermittent or consecutive holiday years) over a five-year period. CONCLUSIONS: Although PC was successful in reducing the burden of active infection, even among those heavily infected, annual CWT did not have a significantly greater impact on disease prevalence or intensity than less intense treatment arms. This may be due to extremely high starting prevalence and intensity in the study area, with frequent exposure to reinfection, or related to challenges in achieving high treatment coverage More frequent treatment had a greater impact on prevalence and intensity of infection when arms were grouped by number of treatments, however, cost efficiency was greater in arms only receiving two treatments. Finally, a significant reduction in prevalence of S. haematobium was seen in adults even in the SBT arms implying the rate of transmission in the community had been decreased, even where only school children have been treated, which has significant logistical and cost-saving implications for a national control programme in justifying CWT

The solar eclipse and associated atmospheric variations observed in South Korea on 22 July 2009

A partial solar eclipse occurred in South Korea on 22 July 2009. It started at 09:30 a.m. and lasted until 12:14 LST with coverage of between 76.8% and 93.1% of the sun. The observed atmospheric effects of the eclipse are presented. It was found that from the onset of the eclipse, solar radiation was reduced by as much as 88.1 ∼ 89.9% at the present research centre. Also, during the eclipse, air temperature decreased slightly or remained almost unchanged. After the eclipse, however, it rose by 2.5 to 4.5°C at observed stations. Meanwhile, relative humidity increased and wind speeds were lowered by the eclipse. Ground-level ozone was observed to decrease during the event

Enkephalon - technological platform to support the diagnosis of alzheimer’s disease through the analysis of resonance images using data mining techniques

Dementia can be considered as a decrease in the cognitive function of the person. The main diseases that appear are Alzheimer and vascular dementia. Today, 47 million people live with dementia around the world. The estimated total cost of dementia worldwide is US $ 818 billion, and it will become a trilliondollar disease by 2019 The vast majority of people with dementia not received a diagnosis, so they are unable to access care and treatment. In Colombia, two out of every five people presented a mental disorder at some point in their lives and 90% of these have not accessed a health service. Here it´s proposed a technological platform so early detection of Alzheimer. This tool complements and validates the diagnosis made by the health professional, based on the application of Machine Learning techniques for the analysis of a dataset, constructed from magnetic resonance imaging, neuropsychological test and the result of a radiological test. A comparative analysis of quality metrics was made, evaluating the performance of different classifier methods: Random subspace, Decorate, BFTree, LMT, Ordinal class classifier, ADTree and Random forest. This allowed us to identify the technique with the highest prediction rate, that was implemented in ENKEPHALON platform
