Specifying of Systolic Pressure and Diastolic Pressure Using Artificial Neural Network Training Algorithm
Ahmed M. Elshewey
The measurements of blood pressure techniques are based on measuring the pressure of the cuff and on sensing the variation of the amplitude of pulsatile. Patient movement is sensitively effected by these measurements. The movements that are slightest unexpected could offset the readings of the automatic blood pressure meter by a large amount or render the readings totally meaningless. In this paper, windkessel models (two element windkessel model, and three element windkessel model) were applied to generate blood pressure measurement. Blood pressure measurement for healthy person varies in the range 80mmHg/120mmHg. Artificial neural network classification is one of the artificial intelligence techniques used for the statistical analysis and classification. Artificial neural network (ANN) is tools for pattern classification computational that have been the matter of research that is renewed. ANN uses several learning algorithms and formats are being used in medical applications, industrial, and academic research artificial neural network were also used in previous studies to estimate blood pressure. In this paper, artificial neural network designs have been used for determining systolic pressure and diastolic pressure, where the input values in the neural network are the values estimated from windkessel models (two element windkessel model, and three element windkessel model). Gradient descent and an algorithm of adaptive learning rate back propagation were used for the training. The result showed that the artificial neural network was more accurate method. However a huge database is required for this method. Both under training and over training will affect the measurement accuracy.

State-owned enterprises governance in Morocco: Measuring efficiency by Sugeno integral
Noureddine ERRAMLI, Mohammed KHALFAOUI
In this article, we are interested in studying the problem of multi-criteria aggregation in the field of governance in Morocco. We propose a new approach based on the integral of Sugeno for aggregation of multidimensional relevance. The main originality of this operator, in addition to its ability to model the interactions between different dimensions of relevance, is its ability to generalize many classic aggregation functions. The results show the effectiveness of our proposal.

The study investigated the influence of family structure on children’s motivation to learn and academic achievement in Minna Metropolis, Niger State of Nigeria. To guide the study, four research questions and four hypotheses were formulated. The study adopted the ex-post facto or casual comparative research design. The population of the study comprised all the 9995 primary five pupils in Minna Metropolis. The sample was made up of 452 primary five pupils in public schools .The academic achievement scores of the pupils for a session were collected using the pupils’ results for three terms. A questionnaire titled “Influence of Family Structure on Children’s Motivation to Learn Questionnaire” was also used to collect data. Mean and Standard Deviation were used to answer the research questions while Analysis of Variance (ANOVA) was used to test the hypotheses. Findings of the study revealed that pupils from monogamous family structure had the highest mean motivation to learn followed by pupils from multiple transitional family structure while the pupils from polygamous family structure had the lowest mean motivation to learn. Further analysis showed that family structure significantly influences pupils’ motivation to learn. However, it was further revealed that family structure has no significant influence on the pupils’ academic achievement. Also, gender has no significant influence on the pupils’ motivation to learn and academic achievement. Based on the findings, it was recommended, among others, that parents should be fully involved in the education of their children and wards by assisting them with their homework and providing other relevant and necessary materials for them.

The current study examined the influence of socio-economic factors on parental expenditure on children’s education at the nursery school level in Delta State, Nigeria. The study covered parents/guardians with children in the nursery school level in both private and public schools in Oshimili North and South Local Government Areas of Delta State, Nigeria. Six(6) research questions and four(4) hypotheses guided the study. The design of this study is ex-post-facto research design. The population of the study was 20,394 parents whose children are in both public and private nursery schools in the study area. The sample for the study comprised 408 parents out of a total population of 20,394 parents sampled by means of stratified random sampling technique. The instrument for data collection was a 4-point rating scale questionnaire titled: Parental Expenditure on Children’s Education Questionnaire developed by the researchers with much insight drawn from literature materials reviewed. The instrument was face validated and the reliability coefficient was 0.79alpha. The researchers analysed the collected data using frequencies, percentages and chi-square statistics. Based on the analysis of data collected, the following are the major findings of the study: Parental expenditure on the education of their children are in the areas of textbooks (97.9%), Cardigan (76.47%), Transportation (62.74%), exercise books (100%), school fees and uniforms (100%), Play materials (48.77%) while only 24.75% engage extra lessons for their children. Over 92. 89% of parents spend between 0-20percent of their income on the education of their children in the nursery school and 29 parents representing 7.11% spend within the 21-40% of income proportion. In the income proportion bracket of 41% and above, no parents representing 0% spend on their children’s education. Results further show that there is a significant difference in the response of parents based on their educational qualification with regards to the parental expenditure on children’s education at the nursery school level; there is no significant difference in the income level of parents and their expenditure on their children’s education; parental occupation significantly influence their expenditure on their children’s education at the nursery school level; and there is a significant difference in the responses of urban and rural parents on their expenditure on children’s education. On account of these findings, conclusions, recommendations and suggestion for further studies were made.

Teachers’ Use of Innovative Practices for Effective Teaching of English Language for Quality Assurance In Nigerian Secondary Schools
Uchenna Lebechi Igbokwe and Cajetan Ikechukwu Egbe
The level of student’s proficiency in English language at all levels of education in Nigeria remains a source of constant concern. Educationists as well as linguists in their various ways have tried to find solutions to this malaise. To ensure quality assurances in language teaching, methodological reviews have taken place in language teaching and learning in Nigeria and innovative practices and processes inherent in the communicate language teaching (CLT) have been recommended. This shift away from the traditional teaching method has produced positive results in many countries, but in Nigeria the performance of students does not justify methodological reviews and recommendations. This paper sets out to find out the extent of teachers’ awareness of the innovative practices inherent in CLT as well as the extent to which these practices are used. Two research questions guided the study. Descriptive survey design was used and data was obtained using both qualitative (interview) and quantitative (questionnaire) methods. Results showed that though an appreciable number of teachers have a head knowledge of CLT, they did not quite understand the practices inherent in the method and therefore minimally used them.

The aim of the study is to examine the effect of recount game on pupils’ achievement and interest in number and numeration in primary schools in Kogi state. Five research questions and five hypotheses guided the study. An experimental research design was adopted for the study. The population for the study was 3,171 pupils from 231 primary schools. The sample constituted 95 numbers of pupils randomly selected from 3 primary schools in Dekina Local Government Area. For data collection, two instruments were used namely: Number and Numeration Achievement Test (NNAT) and Number and Numeration Interest Scale (NNIS). To determine the reliability of the instrument, Cronbach Alpha was used to determine the internal consistency of both instruments. The internal consistency reliability for the interest scale questionnaire was 0.863. The internal consistency reliability of the achievement test for the pupils was analyzed using Kuder-Richardson 20 (K-R20¬¬¬) formular and the internal consistency reliability established was 0.960. The data collected was analyzed using mean, standard deviation, t-test and ANCOVA. The study discovered that recount game have significant effect in pupils achievement and gender. The study also found that both the male and female pupils have interest in number and numeration and finally, recommendations that primary school teachers should incorporate recount games in teaching and learning of number and numeration and in other topics in mathematics.
