Abstract :

This reflection is part of the framework for analyzing public demonstrations during election periods in 2011 and 2018. The objective of this research is to inform the stakeholders (the demonstrators, the press, the police, etc.) how they should act during this period and to demonstrate that liberal democracy requires the embodiment of its fundamental values. Starting from the reflection that interrogates the street as a competitive political space by discussing mainly on the difficulties faced by political and social actors when they consider investing it through the organization of demonstrations. We remained concerned with the concern to give the concept of manifestation, the brief historical overview of the 2011 and 2018 elections, the legal framework and violations of the right to demonstrate in the background, the exercise of the right to freedom of demonstration as well as future prospects.

Abstract :

The objective of this study was to assess the socio-cultural knowledge and uses as well as the cubing rate and carbon dioxide sequestration potential of two forest species (Entandrophragma cylindricum and Khaya grandifoliola) in the Binga Community Reserve. The ethnobotanical survey was conducted using a stratified probability sampling technique. The sample size was determined using the Dagnelie relationship. The dendrometric measurements were carried out in a 12 ha area subdivided into 50 m x 50 m plots, where all trees with a dhp of 10 cm or more were counted. The study showed that both plants are used in traditional medicine to treat 14 diseases. K. grandifoliola is the most cited plant (76.51%) than E. cylindricum (23.49%); the two most cited diseases are generalized pain (29 citations) and malaria (29 citations) with a Jaccard's coefficient of similarity equal to 57%; K. grandifoliola treats more malaria while E. cylindricum is more used in the treatment of generalized pain. For both plants, bark is the most used organ (99.3%) while decoction is the most cited method of recipe preparation (95.3%). The cubing rate of E. cylindricum obeys the mathematical models of polynomial regression (y = -0.0002x2 + 0.2935x - 16.392) and Power (y = 0.0038x1.6976) while that of K. grandifoliola obeys only the polynomial regression (y = 0.0012x2 - 0.0216x + 0.5592). E. cylibdricum sequesters more CO2 (77.10 tonnes/ha) than K. grandifoliola (33.83 tonnes/ha). It is therefore desirable that the results obtained should encourage local stakeholders (local population) and institutions in charge of forestry administration to work towards establishing standards capable of guaranteeing rational management and sustainable development of these forest species through a community bio-cultural protocol.

Abstract :

Any company must seek to improve its management organisation in order to maximise its performance and secure its management with the help of high-performance ICT tools for processing information. Since it does not have its own naval operating tool, the CML (Congolese Maritime Lines, formerly CMDC) has to resort to chartering ships. This mode of operation does not provide it with a sufficient financial cushion to meet its various expenses. In order to help the General Management to position a vessel as a single trip or round trip, the Commercial Management has to base the decision on simulation studies allowing identifying the profitability of each chartered vessel per trip. In the context of this study, the concern is focused on the design and implementation of a relational type of database that can allow LMC to gauge the results of its chartered vessels per voyage.

Abstract :

Computer Aided Mapping (CAD) is based on the use of Geographic Information Systems, high resolution images and GPS (Global Positioning System) receivers for the survey of x and y coordinates. This leads to spatial analysis of the acquired images and the use of geo-spatial technologies, which in turn leads to the production of maps, for which standard data layers such as the shape file of administrative boundaries, roads, cities, territories and hydrographies are required as a basis for mapping, census and data collection activities. The automatic processing of data from upstream census mapping activities has both advantages, the first is efficiency, which is reflected in the amount of output that can be obtained per unit of input, this shows that more can be done at a lower cost, on the one hand, the utility advantage is reflected in the effects of programmes benefiting from improved information, on the other. Digital census mapping is thus computer-assisted mapping, using computer technology and taking advantage of new geo-spatial technologies to produce better maps faster and improve the overall quality of census data than updating it.

Abstract :

This work consisted in evaluating the nitrite content of meat products sold in Kinshasa. To do this, we analysed by absorption spectrophotometry a total of 20 samples, 10 of which were of local origin and 10 others imported to conduct a comparative study. The results obtained revealed that out of the sausages analysed, those of local origin all contained nitrite levels either lower or higher than the European standard which is 100 to 150 mg/kg. The same situation was observed in seven imported sausages, while the other three contained nitrite levels recommended by the European standard.

Abstract :

The present work consisted in assessing the oil yield of the two sesame varieties, namely Kalayibantu and Kasaï, as well as their physico-chemical qualities by means of traditional manual extraction. After extraction, the average yield calculated in oil for the two varieties was higher for those extracted from the Kalayibantu variety than for those obtained from the Kasaï variety. Concerning the physico-chemical parameters, the following results were found, one showing the calculated indices of the oils extracted from the Kalayibantu variety (Ia=1.4; Ip=10.7; Io= 27.9; Is=15.2; Ie=13.8) and the other those of the oils from the Kasaï variety (Ia= 1.5; Ip=5.9; Io= 7.9; Is= 18.6; Ie=17.1). These results lead us to say that the oils extracted from the Kalayibantu variety have an acceptable profile in terms of yield and physico-chemical quality.

Abstract :

The aim of this study was to analyze the influence of television on juvenile delinquency commonly known as Kuluna in Kinshasa. In order to find a lasting solution to this social malaise, a survey using the simple random sampling technique was conducted among 1700 subjects, mostly young, whose ages ranged from 13 to 26 years, in which there were 844 male and 836 female individuals, drawn from the population of the Kingasani district, which has a population of 17,000. The results of this study indicate that television plays a socially perverse role. Violence in the social stratum of youth and the media, mainly television through its channels, contribute to the social production of juvenile delinquency in poor areas of Kinshasa. The family thus plays an important role in the implementation of an intrafamilial communication likely to protect the children against the influence of the televised channels on the ethology and the violence among the young people.

Abstract :

Unmedicated abortions are criminal social acts capable of preventing the development of this social stratum composed of young girls. In this study, the dialectical method and the cluster or stratified sampling technique where the target population is divided into homogeneous subgroups, i.e., exclusively girls (5,609 individuals out of a population density of 56,095 female subjects) were used in order to better understand this dysfunctional social scourge. The sociological approach consisted in searching for the social aetiologies of non-medicalized abortions, in analysing the multiple consequences in order to find effective therapeutic orientations to protect this female juvenile mass in total perdition. The results of this research show that preventive approaches are effective, including intra-family communication. Also, this field investigation revealed that the precariousness of parents, iatrogenic group influences, parental irresponsibility, lack of frank intrafamilial communication concerning sexuality, perverse curiosity, etc. are social aetiologies of non-medicalized abortions.
