Abstract :

Neonatal mortality disturbs the whole of humanity. Its frequency remains very high throughout the world, but more so in developing countries. The DRC is ranked among the countries with the highest number of neonatal deaths in the world with the ratio of 47 per 1000 live births, (Kalonji DC et al 2018). Indeed, the province of Kongo Central has not remained indifferent to this health problem. With a view to improving newborn health during the neonatal period, the present study is conducted and envisages identifying the determinants of neonatal mortality in Kongo Central Province. For this study, the general population consisted of all newborns in the Province of Kongo Central from 2021 to 2022. A random sample of 117 cases met the inclusion criteria, of which we matched 1 case to 2 controls. After data analysis, we found the following results: the overall neonatal mortality rate was 333 per thousand live births. The logistic regression model identified the following determinants of neonatal mortality: age (OR= 1.16562 IC95 [1.035635 -1.3163]. p=0.0105), age less than 2 years (OR= 2.01966 IC95 [1.021601-4.058]. p=0.0449) and acute fetal distress (OR=2.62027IC95 [1.179464-5.878]. p=0.0181). In order to improve neonatal health, pregnant women should be made aware of the importance of prenatal consultations for early detection and appropriate management of high-risk pregnancies. They should be present at the onset of labor and give birth in the presence of qualified personnel.

Abstract :

This study aims to assess and monitor factors associated with COVID-19 vaccination acceptance among residents of the N’djili health zone. Using a methodological approach, we conducted survey among residents to collect data on their knowledge, attitudes, and perceptions about the vaccine. The results show that several factors influence vaccination acceptance, such as education level, access to information, trust in health authorities, and personal experiences related to COVID-19. Data analysis helps identify appropriate communication strategies to improve vaccine acceptance and mobeilize the population.

Abstract :

This study examines factors associated with maternal mortality from 01 January 2020 to 31 December 2023 at the general referral hospital and in health centres and maternity units in the Kisenso health zone in the Kinshasa provincial health division. We used advanced statistics, with survival analysis performed using the Kaplan Meier estimator. The Cox model helped us to identify the factors associated with maternal mortality, as it is suitable for this type of study. The results of the analysis of our data show that the factors associated with maternal mortality of pregnant women and women who have recently given birth are: factors related to pregnancy, factors related to management and factors related to gynaecological and obstetric characteristics. Taking these factors into account can contribute to the implementation of interventions aimed at significantly reducing maternal mortality at central, intermediate and operational levels.

Abstract :

This work involves the development of a bioplastic replacement for non-degradable plastics in packaging. The objective was to produce polylactic acid (PLA) from sugarcane molasses with locally produced Lactobacillus delbrucckii. Polylactic acid is a biosourced and biodegradable polymer, it can be plasticized. The lactic acid bacteria necessary for the synthesis were isolated and identified as Lactobacillus delbrucckii following their characteristics. The sugar cane molasses used came from the KwiluNgongo sugar mill with a concentration of 410.9 g/L of fermentable sugar. 1L of diluted molasses was fermented with the inoculum of Lactobacillus delbrucckii in a ratio of 10/1. This fermentation produced 98 g of lactic acid after purification (63.6%). Lactic acid was polymerized to polylactic acid (92%), via lactide (78.46%), by ring opening. Lactobacillus delbrucckii colonies were characterized by Gram staining, catalase test, morphology, appearance of the colony and mode of fermentation. The Brix degree, pH, density and fermentable sugar level were determined on the molasses. The polymer obtained had a brittle behavior when heated and its mixture with 5% glycerol gelled more weakly than in the presence of 10% glycerol.

Abstract :

This study is based on the entrepreneurial intentions of young Congolese who live in an economic environment that is very rich in natural resources but relatively poor in the spirit of entrepreneurship and capitalising on their country's natural resources. Few studies have been carried out into the entrepreneurial intentions of young people in the Congolese context. This is why we wanted to make a contribution in this field by using documentary techniques through an analysis of the literature and the inductive method to arrive at a synthesis. We concluded that the capitalisation of natural resources in the entrepreneurial intention of young Congolese remains an important step for the development of entrepreneurship in the country.

Abstract :

This article consists of a petrographic study of the Kwilu limestone in the Lukala subgroup mined at Songololo by the Cimenterie Kongo (CIMKO). From a macroscopic point of view, 22 boreholes were described and divided into three lithofacies. Analysis of the samples brought back to the laboratory showed micrite diagenesis, transforming into microsparite and sparite. The interest of this study lies on the petrographic study of the different types of lithofacies in the mined limestone and their classification in the local stratigraphic scale. Three lithofacies types were identified: light grey, greenish grey and dark grey, classified within the Bulu and Luanza formations of the Kwilu unit.

Abstract :

The administrative services of the Ministry of Health are not immune to the multifaceted crises affecting the Congolese public administration. As administration is both the foundation and backbone of public management in a country, the Democratic Republic of the Congo is a nation where archival science, in all its nobility, plays a vital role in good governance. If administrations continue to thrive at the beginning of the 20th century, it is due to the importance of archival documents, which every modern and organized nation strives to preserve well, as an essential tool of national memory. Archives are data with an indefinite lifespan and cannot be materials that disappear. The observation within the General Secretariat of Health is that archives are thrown haphazardly into dark rooms where they are exposed to the elements and various kinds of rodents. Under these conditions, the disappearance of historical data is inevitable, which could constitute a significant loss, especially as some documents exist in a single copy and, once destroyed, they cannot be reconstructed.

Abstract :

Planetary gearboxes are essential for reducing the rotational speed of electric motors to a suitable level for cement production equipment, such as grinders and kilns. By integrating a preventative maintenance strategy for these reducers, the cement plant can minimize unplanned downtime, optimize performance and extend the useful life of the equipment. This involves regular inspections, replacing worn parts before they fail, and properly lubricating components to ensure optimal operation. By investing in effective preventative maintenance, cement plants can save money in the long term by avoiding high costs associated with emergency repairs and production interruptions. The impact of a planetary gearbox in a cement plant therefore becomes significant.
