Since the Spanish conquest, Peru stopped being autonomous and joined the emerging economy of world capitalism. That is, it ceased to be a closed economy and with it two new variables appeared in its economy: exports and imports. The transition to an independent nation did not essentially change this condition of open economy, which was reinforced by the process of globalization of the second half of the 20th century.In this regard, exports have been a significant variable for the economy, for better or for worse. For good, when the international demand generated better prices that were naturally favorable for Peru. To the bad, when international crises generated internal crises in Peru expressed in an economic contraction. To this has been added the problem of the competitiveness of our exports. This is where the government has tried to favor export expansion with trade policy measures, ...

The objective of the research has been to determine the relationship between the quality of the municipal service and the satisfaction of the citizens of Piura 2021. To meet this objective, we collected data using the survey technique and, as an instrument, the questionnaire, which we applied to a random sample of 384 citizens. Once the data was collected, we created a database using SPSS Version 25, from which we described the variables (descriptive statistics) and the corresponding hypothesis tests (inferential statistics). The main conclusion we have reached, with the investigation, has been that there is a significant relationship between the quality of the municipal service and the satisfaction of the citizens of Piura 2021.

The objective of the research has been to determine the relationship that exists between municipal management and the quality of service in the Provincial Municipality of Abancay, 2021. In this sense, a questionnaire has been applied to 384 citizens to know their perception of these variables. With the data collected, we organized a database in SPSS software, with which we were able to describe the behavior of the variables and infer whether there was a significant relationship between them or, on the contrary, they were independent, using the chi square test for this. because the variables are qualitative and we have more than 50 data per variable. According to the results of the investigation, it has been shown that there is a significant relationship between municipal management and the quality of service in the Provincial Municipality of Abancay, 2021.

  In general, when the river flow increases, a scour phenomenon will occur, in which the substructure of the bridge, be it abutment and / or piers, will be affected, resulting in a partial or total collapse of the structure. All of the above is the key to achieving our research objectives, which is to carry out an evaluation and protection design against the hydraulic scour process of the Unocolla bridge in the city of Juliaca, Puno. The population will be the Unocolla bridge and the sample will be a substructure of the bridge. The method used is applied and its design is pure experimental, using quantitative methods, in which the research problem is described as realistic results. To determine the scour effects, topographic, hydrological and sedimentological information was collected to later carry out hydraulic modeling in the Hec-Ras program. Scour depths were determined in refer...
