Through this study, we want to explain stress through the coping strategies used by agents and civil servants in the city of Kisangani in the Democratic Republic of Congo. After analyzing the data, we realized that to control stress at work, respondents do not use the different dimensions in the same way. In the order of succession of these dimensions, appear value conversion, acceptance, behavioral and social withdrawal, cognitive control vs planning and addictiveness. Also, we have found that all coping strategies are used, although not in the same way. Nonetheless, there is conversion that comes first, followed by control, with refusal and withdrawal taking third and fourth place respectively, social support and, lastly, focus. In the same vein, the three fields of the Toulouse coping scale (ETC) are operated in roughly the same way. Finally, the two categories of ETC coping (positive coping and negative coping) are used indiscriminately by officials of the State of the City of Kisangani, with an emphasis on negative coping (81.16) than positive (80, 93).

In undertaking this investigation, the main concern is to have an appropriate instrument adapted to the environment of workers in Kisangani to fully apprehend professional exhaustion or burnout at work. To do this, two approaches can be put to good use by the researcher, either to design his own tools in case they do not exist, or to adapt those from other skies. This research is part of the second approach, which proposes an application trial of a tool concerning professional burnout, in particular the Maslach Burnout Inventory (MBI). It is in order to see whether it is, yes or not, adapted to the reality of the environment and to adopt it in the scientific investigations in the environment of workers of Kisangani. Research is working on the metrological qualities of the Maslach Burnout Inventory (MBI). In the validation of the MBI, attention was focused on the precision entered from the Cronbach's alpha coefficient and the validity by the homogeneity of the tool through the item-test correlation coefficient. Three types of validity were the subject of the MBI, namely facial or content validity, construct or trait validity and nomological or predictive validity.

This study aims to see if student gender can influence academic success in the first cycle of study at Kisangani University. To verify the existence of an association between the sex of the students and the modalities of the success, we resorted to the test of chi-square of the independence. It allowed us to accept the null hypothesis of the independence between sex and success in the two promotions of the 1st and 2nd graduates with a slight superiority of the students in the modality of receipts. The observation is similar in 3rd graduate with a superiority rather of students.

The ecological crisis as well as his/her/its demonstrations captivates the attention of the entire humanity. In our survey, we left from the question: what they are the demonstrations of the ecological crisis? This question allowed us to fix us two objectives in our survey: to present the different demonstrations of the ecological crisis and their consequences on the population; to show that the demonstration of the ecological crisis varies from a middle to another. To reach these two objectives, we consulted the documents treating the ecological crisis and the investigation done in the city of Kisangani and the farming city of Ikela. The result shows that in the city of Kisangani and the farming city of Ikela the heat, the drought and the floodings are the demonstrations of the ecological crisis. The heat is observed in the cities and the drought in the farming surroundings. What shows that the demonstrations of the different ecological crisis according to the middle. At the end, we raised some questions that can be the subject of the ulterior studies.
