A total of 51 samples of Distichodus fasciolatus (Mboto in Lingala), Mormyrops anguilloides (Monzanda/Nzanda) and Schilbe mystus (Ndangwa/lilangwa) fish, gutted and separated from the gills, were captured from the Kinsuka fishing site in Pool Malebo on the Congo River in Kinshasa to determine lead and cadmium concentrations, and to assess the health risk associated with their continued consumption. After spectrophotometric analysis with HACH - DR 2400 in accordance with the laboratory's operating procedure, it appears that all the species of fish analyzed are contaminated with lead and cadmium at concentrations far above the European Union edibility standard. The continued consumption of 14.24 grams per day of fish from the Kinsuka fishing site poses the obvious risk of developing chronic disease throughout life, especially in children. The hazard quotients and the associated hazard quotients, whether for children or for adults, are far greater than 1. This risk could become even worse when the purchasing power of consumers is improved in the future. It is up to the government to ban the consumption of these fish and to take binding measures to reduce the contamination of aquatic ecosystems, to introduce national standards for the discharge of industrial wastewater and for foodstuffs intended for human consumption.

Fish Tilapia nilotica, Mormyrops anguilloides and Schilbe mystus, captured at port Socopla-Lomata on the Congo River in Mbandaka were analyzed by X-ray fluorescence spectrometer, brand Xepos III in accordance with the laboratory’s operating mode; to assess lead, cadmium and mercury contamination. The results showed concentrations higher than the edibility standards of the European Union and the concentrations observed in the water of the fishing site. The species Mormyrops anguilloides accumulates more cadmium while lead and mercury are more accumulated in Tilapia nilotica.

Severe acute malnutrition remains crucial in South Kivu in general and in the Bagira health zone in particular. Severe emaciation affects 7.8% of South Kivu children against 10% for the entire DRC. In 2012 the Bagira health zone, experts found that the prevalence of severe acute malnutrition would be 2.4% and global acute malnutrition of 6.1% against 7.8% for the entire province. The overall objective of this study is to contribute to improving the management of severe acute malnutrition in Bagira health zone. This is an assessment of the current level of implementation support for severe acute malnutrition protocol. This cohort study has allowed us to study the evolution of anthropometric parameters children admitted to the output of the UNTI and output to 6 months. Subsequently we studied the risk factors for death among the discharged malnourished child and have experienced the breakdown of inputs. We found that changes in the weight-for-height z-score for most children was slow (<- 3SD) and the height gain in three months out of the UNTI for children who have experienced more than 30 days failure (P=0.005). Influenced the deaths of children in the community are anemia (P = 0.03), infection represented by fever (P = 0.03), the level of education of mothers (P = 0.03) the profession of the mothers (P = 0.03), non-worming (P=0.02) and the status of the mother (P=0.03). The fight against severe acute malnutrition implies the availability of inputs and preventative measures to ensure good survival for children ZS Bagira.

In conducting this study, we sought to determine the difficulties encountered by elementary school students in BENA-DIBELE in mathematics and French and to identify the strategies used by teachers to support students with difficulties. Based on an occasional sample of 60 teachers, we realized that the students of BENA-DIBELE experience learning difficulties. These include problems with spelling (23.5%), agreement (23.5%), writing (18%), diction (17.5%) and pronunciation (17%) in French; and problems with solving operations (50%), thinking (45.35%) and measurement (4.65%) in mathematics. To overcome these difficulties, teachers use several strategies to support these students. These include remediation (13.87%), assigning homework (17.65%) and questioning (13.66%), correcting homework (9.34%), submitting to application exercises (15.55%), checking work (6.30%) and assigning homework (11.75%). From the above, it is interesting that teachers multiply directed and homework assignments to help students better internalize the concepts learned and prepare their transfer to the field of everyday life. Also, it is necessary to facilitate the exchange of information between parents and teachers, both physically and through the communication notebooks, to inform them of their children's performance.

This study examines the musical communication of the Ode to the Fatherland. Positioning itself at the level of musicology and social communication, it analyzes the content of that song, that is to say, the constituent elements of its melody, rhythm, harmony and lyrics in order to reveal its deep meaning, and thus to understand what it is deals with, to who it is addressed and for what it is about. The results of the various musical and textual analyses reveal how the Ode to the Fatherland, while it presents itself as a musical communication, is also a social communication. If the former lets hear the sadness and the determination of the Ivorian Man, in a full conscience of the pluralities of opinions and ideas, the latter calls for the qualitative change by inviting to opt courageously for the overcoming in order to go forward. In a congruence of the melody and the words, the Ode appears thus as a true awakener of national patriotic conscience: it speaks of the society to the society to provoke a sacred union able to create the agreement between the daughters and sons of the nation and to put back the country on its feet.

« Non-economists » strongly criticize the concept of GDP because it gives too much space to the market, to finance and less to the non-market, social, or environmental costs of production, human rights or freedoms. Considering all the proposed elements already make the calculation of a country’s GDP more complex, what about the GDP of separate entities within a country? States such as Canada, the United Kingdom, France, the United States (US), and recently Tunisia have made the regional GDP an important instrument of their economic and social policies. As structured economies, largely monetized and equipped with statistical tools, they have developed and applied efficient calculation methods. This article is intended to be forward-looking/exploratory for the calculation of the regional GDP in DR Congo, a country characterized, in particular, by a significant weight of the informal sector; a high rate of economic and financial crime (money laundering, embezzlement, large-scale corruption of policymakers, government leaders, financial authorities, public, mixed or private companies, etc.), and a high contribution of its diaspora established throughout the world (in the household management expenditure in DR Congo).
