Growth Pattern of Silver Barb, Barbonymus gonionotus (Bleeker, 1850) in the Cipanas Reservoir Plan of West Java Province []

Silver Barb (Barbonymus gonionotus) is a native fish that is well known in Indonesia and has the potential to become one of the aquacul-ture commodities. Silver Barb can live well in rivers, flood plains to reservoirs. In 2016 the construction of the Cipanas Dam began to be carried out which will hamper the flow of the Cipanas River so that it changes the pattern of river flow from flowing into stagnant which indirectly impacts on the habitat of aquatic organisms. Changes in river habitat will have an impact on the survival of these organisms, both growth, reproduction and eating habits. Therefore, this research aims to analyze the growth pattern of Silver Barb in the Cipanas River which has the potential to become a cultivation species in the Cipanas Reservoir in West Java Province. The method used is a survey method with purposive sampling technique at the coordinates of the sampling point 6° 41' 51" LS - 6° 38' 53" LS and 108° 01' 32" BT - 108° 02' 53" BT. The research was conducted in June - October 2018. Silver Barb caught in the waters of the Cipanas River consist of sev-en size classes. The most caught size classes are fish that are still in the growth stage, measuring 125 - 146 mm by 25.71%. Fish growth patterns follow the regression equation y = 3.1692 - 0.000006x. b = 3.1692 means that the growth pattern is positive allometric. Fish reach maximum weight when measuring between 147 - 168 mm in length. The condition factor of Silver Barb fish ranged from 0.82 - 1.10 with weight gain proportional to the increase in length to a certain length (point of reflection).


Abstract This study investigated the psychological impact of academic information and gender on the students’ choice of university, among 100 levels undergraduate students of UNN, the participants were 200 students drawn from two schools, University of Nigeria, Nsukka (UNN) and Enugu State University of Science and Technology (ESUT). Questionnaires were used to collect the responses for the study which was developed by researcher and validated by some experts in the UNN Department of Psychology. Two null hypotheses were postulated. The first stated that there would be no statistically significant difference of academic information on the choice of university. The second stated that there would be no statistically significant gender difference on the choice of university. The Chi-square (X2) analysis of data on data on the first hypothesis showed X2 = (1, 20.78) p<.0.05 and the second analysis produced X2 (1, 0.02) p>0.05. The findings indicated (1) statistically significant impact of academic information on choice of university. (2) No statistically significant effect of gender on choice of university. The results were discussed. The implication of this study show that students requires information about educational and occupational training inside and outside school; to eradicate stereotypes in choice of university and help youths to be very informed before choosing a particular university. The study concludes that, choice of university involves a person’s total life. An adequate understanding of how an individual selects a particular occupation among several alternatives is a basic step towards arresting future career maladjustment and its associated problems. More so, it will facilitate efficient use of human resources for good functioning of the economy.

ABSTRACT Background: Malaria remains one of the major public health burdens in Africa in that it is one of the common diagnosis made by prescribers in all out patient departments across the African continent. The infection affects about 3.4 billion people worldwide and accounted for the deaths of 1.2 billion people across the world. The worrying situation about the infection is that of the over-diagnosis of the disease and over prescription of antimalarial to persons who have not been tested for the presence of the parasite before commencing treatment. Objective: The objective of the study was to assess how community health officers manage malaria in children under 5 years at the CHPS compounds and to assess whether the use of malaria RDT has contributed to a reduction in over diagnosis of malaria. Method: A cross sectional study involving simple random sampling method was used to select two or three CHOs from each of the 23 CHPS compounds in the Birim Central Municipality. Data was collected using face to face interview and paper questionnaire. The data was then entered into MS excel 2013 package and transferred into Stata version 15 for analysis. The Pearson’s chi-square and Fishers’ exact tests of association were used to determine the association or relationship between participants’ background characteristics and the level of knowledge on malaria management. The simple and multiple logistic regression models were used to determine the crude and adjusted odds ratio respectively in quantifying the factors that influence participants level of knowledge on malaria management. Results: The mean knowledge score on the scale of 0 to 1 was 0.64 with a standard deviation of 0.11. Also the median score of the overall knowledge of study participants was 0.67 also with an interquartile range of 0.11(thus 0.70 minus 0.59). While 25% of the study participants scored below 0.59, the top 25% of the study participants scored at least 0.70 both on the scale of 0 to 1. With a score of 0.70 as the least threshold of the high knowledge on management of malaria cases, 36.4% (n=24) of the study participants had high knowledge on management of malaria cases with an estimated 95% confidence interval of 24.9% to 49.1%. Conclusion: Testing with malaria RDT before commencing antimalarial treatment was 95.45% from the study. This was higher than the national prevalence rate of RDT testing which stood at 83.9% in 2017. Findings from the study also showed that the use of malaria RDT in managing malaria in the CHPS compounds has drastically reduced the over diagnosis of malaria and the over prescription of antimalarial drugs.

Insects are categorized in the biotic composition of the forest, and plays very important role in balancing the ecological system of the forest. Large parts of its tropical rainforest now are logged-over area and now some of it undergoes the regeneration phase. This condition may affect the species composition of insects in the forest as the forest ecosystem really depending on each other to survive. However, until today there are still limited scientific study has been conducted regarding the insects composition and biodiversity of between these forests area. The purpose of this study is to identify insect order under two different type of forest, to assess the efficiency of different types of trap and to determine the species composition and diversity between forest edge and regenerated secondary forest Bintulu, Sarawak. The research was conducted in Sarawak, which is located 3°12’20.1”N 113°05’34.1”E. This research was carried out for 10 weeks at four areas namely Riparian Forest, Rehabilitation Forest, Regenerated Secondary Forest and Forest Edge. Three stages involved are insect trap method, insect identification and data analysis. Assessment of the species diversity of the insects between the two forest area are based on Shannon-Wieneri index where it focused on insects species richness and evenness. The total number of insect order found from the 2 types of forest is 5 orders, Coleoptera, Blattodae, Hemiptera, Hymenoptera. It was found that the two forests had the same order of insects. The Shannon-Wieneri index of diversity (H’) is to characterize species diversity in a community where it is another index that is commonly used. The Shannon-Wiener index diversity for Forest Edge (H’) shows the value 1.10 and for Regenerated Secondary Forest, the value is 0.833. The H’ for Forest Edge is more diversity compare than Regenerated Secondary Forest because the values for H’ is higher compare the Regenerated Secondary Forest. The higher of Shannon-Wiener index diversity (H’), the more diversity of insect species. For Forest Edge, the species evenness is 1.00 where that mean that all insect order have the same frequency. Typically values are generally between 1.5 and 3.5 in most ecological studies and indicate for diversity, and the index is rarely greater than 4. For Regenerated Secondary Forest, the species evenness is 0.755. The species evenness for that forest a little bit low than Forest Edge.The normalizes Shannon-Wiener Index of Diversity a value between 0 and 1. The nearest the values into 0 indicate that the insect species dominant into 1 species. The value nearest to the 1, the insect species more evenness. From the result obtain, it can be conclude that Forest Edge has more insects diversity compare to Regenerated Secondary Forest.

Respiratory illness and associated factors among women households using charcoal for cooking in Gondar town, Ethiopia: A cross-sectional study []

Abstract Background In Ethiopia, less than 5% of the population has access to clean fuels. Exposure to the pollutants from charcoal cooking leads to respiratory illness among women households. There is a dearth of data about women health-related to biomass fuel cooking in Ethiopia. Hence, this study was set out to establish the burden of respiratory diseases among women households using charcoal cooking, its exposure, and factors associated in Gondar town, Ethiopia. Methods A community-based cross-sectional study was conducted using systematic random sampling method. A total of 285 women household using charcoal for cooking participated in the study. Self-reported symptoms of respiratory illness and factors associated was collected using a structured questionnaire. Descriptive statistics and regression model was employed to analyze data. Results Using the operational definition for respiratory illness, the prevalence of respiratory illness among charcoal cooking women was found to be 48.1% and the most common symptom reported was cough. Women households who lacked formal education (AOR 1.96, 95% CI: 1.62, 6.51), indoor cooking (AOR 2.57, 95% CI: 1.23, 5.39), self-reported inadequate ventilation facility at home is about 1.7 times associated with respiratory illness. Discussion and conclusion The higher prevalence reported in this study relates to the fact that only less than 5% of Ethiopian population have access to clean fuels. Compare and contrast was inconvenient due to the inconsistence and variability among studies conducted in Sub-Saharan Africa. Still, the higher prevalence of respiratory illness among Ethiopian women households is alarming and demands attention to improve women health.

Problems faced by Transgenders during their Schooling []

This research study examines Problems of Transgenders during their schooling. Transgenders play a vital role in India. The main problem is the stigma and rejection of the transgenders face in society. Lack of access to education and non-availability of jobs often forces them to take prostitution. But still, apart from these views there are some transgenders persons who are brave enough to make their way to the mainstream, achieve their goals and prove that trans people are as capable and deserving as any other Indian, thus breaking the sterotype. The sample of the study comprise of 30 transgenders from Chidambaram, Thanjavur Districts in Tamilnadu. The survey method was employed for collecting the data and was analyzed using descriptive and inferential statistical techniques. It was found that there is no relationship between problems of transgenders during their schooling.

Backward feature elimination and missing values ratio techniques for dimensionality reduction in data mining []

A data warehouse stores too much data from different sources and data mining is the process that we use to extract this data sets from the data warehouse. During this process however too much data that is unnecessary is extracted and this is what we are terming as large dimensionality rates. This research therefore is aiming at looking at various techniques that can be used to minimize this tendency of getting too much unnecessary data sets from the data warehouse. In this thesis we are going to use two techniques to reduce this tendency, the first technique is backward feature elimination where at a given iteration, the selected classification algorithm is trained on n input features, during this technique the process starts with all the columns and fields contained in the data sets,however it is at this point that it starts removing the least significant data sets including their features at each iteration hence improving the accuracy of the data.Another technique is missing values ratio which aims at removing columns with missing values.The use of these two techniques will not only reduce the dimensionality rates but also improve on algorithm speed and performance.The paper discusses a hybrid framework that combines the two algorithms with an aim of improving the quality of extracted data and speed at which data miners can interpret the information from the warehouse.
