Bayesian Networks as Support to Project Management: Optimization of Decision-Making of a Project Developed through the Life Cycle Canvas Model

Leandro Aparecido da Silva, Ana Eliza Galvão Cortez, Manoel Veras de Sousa Neto and Afrânio Galdino de Araújo
Companies and managers need to solve problems and make decisions in environments that have inaccurate variables. Managers must have tools and methods capable of dealing with the uncertainty that is inherent in the job. Bayesian networks (RB) emerge as an imperative method capable of working with an approach that is adequate to work with uncertainties. Another growing demand in management is the search for visual tools that are suitable for a greater amount of information in one or a few illustrations. In the scope of project management, Life Cycle Canvas (LCC) presents itself as a good alternative. Observing the importance and the need of managers to use intuitive tools that can help the decision-making process, the study seeks to know how to improve the monitoring status of a project developed in LCC through the aid of a multicriteria system based on an RB structure. In this context, the objective of the study will be to optimize the monitoring status of a project structured in LCC through a measurement model developed in an RB structure. The study used the Netica tool for the development of RB. The research analyzed two simulations; however, the developed RB allows the interaction of 2,450 total conditional probabilities.

Total Quality Management (TQM) Practices and Institutional Effectiveness of Secondary Schools in Cross River State, Nigeria

Chuktu, Onyinye
This study investigated the influence of Total Quality Management (TQM) practices on institutional effectiveness of secondary schools in Cross River State, Nigeria. To achieve the aim of this study, two research questions were raised and two hypotheses were formulated to guide the study. The study adopted a survey research design. The census sampling technique was used since the population of the study was manageable by the researcher. Two hundred and forty six (246) principals constituted the sample, while a questionnaire titled Total Quality Management Practices and Institutional Effectiveness Questionnaire (TQMPIEQ) was used for data collection. The questionnaire was validated by two experts in Measurement and Evaluation. Cronbach alpha reliability estimate ranging from .72 to .91 for the sub scales was obtained as a measure of internal consistency for the instrument. The coefficients of the sub scales were high for the instrument to be considered reliable and consistent. The test statistics used for data analysis was One Way Analysis of Variance and multiple regression analysis. The result of the analysis showed that Total Quality Management in fund management practice and facilities/equipment management practice significantly influences institutional effectiveness `of secondary schools in terms of organisational innovations, learning environment and learning outcome in Cross River State. It was recommended among others that School administrators should ensure that funds that are provided in schools are judiciously managed in order to enhance teaching and learning as well as provide a suitable learning environment in the school.

Pregnancy is an important event in a woman’s life; the body of a pregnant woman goes through different forms of changes and these changes are as a result of the body’s physiological response to stimuli principally from the pregnancy hormones. On daily basis, the changes that the body undergo during pregnancy can sometimes be disturbing and unbearable but through adequate patient education and self-management with simple home remedies, these minor discomforts can be managed well. Hence, this study enhanced the knowledge of pregnant women on self-management of minor disorders of pregnancy in a State Specialist Hospital, Osogbo, Nigeria.
This study utilized one group pre-test, post-test quasi experimental design. Total enumeration method was used in recruiting 95 pregnant women. Two instruments namely: pregnant woman demographic data (PW-DD) and Test paper on Knowledge of Pregnant Women on Self-Management of Minor Disorders of Pregnancy (TP-KPWSMMD) with Cronbach’s alpha of 0.81were used for data collection. An enhancing training package was used as an intervention to train the pregnant women on management of minor disorders of pregnancy. Descriptive statistics was used to answer five research questions while inferential statistics of paired t-test was used to test the three hypotheses of the study at 0.05level of significance.
There were significant differences between pre and post intervention knowledge mean score of self-management of minor disorders of pregnancy on the basis of education level ( p = 0.00) and on the basis of gravidity (, p = 0.00).
In conclusion, the knowledge of pregnant women on self-management of minor disorders of pregnancy was found to be poor prior intervention but a tremendous improvement after intervention was recorded. The training package utilized in this study enhanced the knowledge of pregnant women on self-management of minor disorders of pregnancy thus preventing complications. It is therefore recommended that Midwives should take it as a responsibility to train pregnant women during ante natal period.

Effect of a Maternal Health Education Package in Identifying Obstetric Complications by Pregnant Women in Tertiary Healthcare Institutions in Ogun State, Nigeria

Okwuikpo, Margaret I., Sowunmi, Christiana O., Leslie, Tabitha A., Okueso, Grace O., Maitanmi, Julius,O. and Ajaegbu, Victoria U.
This study assessed the effectiveness of a maternal health education package in identifying obstetric complications by pregnant women in tertiary health care institutions in Ogun state, Nigeria. The study was a quasi-experimental quantitative research that utilized both experimental and control group, convenience sampling method was used to select 20 participants for each group making a total of 40 participants and a closed ended structured questionnaire containing 63 items in 4 sections was used to gather data. Face and content validity of the instrument was ensured through vetting by experts in the field of study and reliability was established at 0.71 using Cronbach Alpha Coefficient. The study lasted for four weeks; the experimental group, after gathering of pretest data, was exposed to series of health education on causes, predisposing factors, signs and symptoms, what to do and possible complications of obstetric heamorrhage, hypertensive disorders of pregnancy and obstructed labour, after which a post test was administered. The control group was not exposed to the health education package; the researchers collected the pre test and returned 3 weeks after to gather the post test. Data retrieved from both the control and experimental group were coded and analysized using Statistical Package for Social Sciences (SPSS) version 22. Descriptive statistics were used to answer three research questions asked while student T-test was used to test the two hypotheses of the study. Findings from the analysis showed a significant difference between the pre knowledge and post knowledge of obstetric complications among the experimental group, and a significant difference between the control and experimental group on the identification of obstetric complications. The study concluded that health education given to pregnant women was effective in raising the level of awareness of women about obstetric complications, it was therefore recommended that health care givers should painstakingly provide, on continuous basis, adequate and specific information to women during antenatal visit as a way of empowering them to be on the lookout for danger signs of pregnancy.

Rogério Teixeira de Oliveira and Edjofli Dantas Viana

This article analyzes the February 2017 Common National Curriculum Base, the updates to the National Curriculum Guidelines for Secondary Education, November 2018 and the updates to the General National Curriculum Guidelines for Professional and Technological Education, of January 2021 in Brazil and its directions in line with the neoliberal agenda. For this purpose, a theoretical study was carried out, based on bibliographic research and educational legislation. This article aims to verify the correlation of educational policy between 2017 and 2021 and its overlap with the neoliberal political direction. The results of the study demonstrate that the educational legislation of the observed period was organized for the realization of a liberal direction within the modality. Capitalist production, that is, it has elements that aim at the formation of subjects to be prepared only for work and not for an education that contributes to their human and collective formation.
