Introduction: This article is the product of the research “Clustering Framework to Cope with COVID-19 for Cities in Turkey”, developed at Bayburt University in 2021. Problem: Turkey's risk map, presented in January 2021, to take local decisions in tackling the COVID-19 pandemic was based on confirmed cases only. Health, socio-economic and environmental indicators are also important for management decisions of COVID-19. The risk map to be designed by adding these indicators will support more effective decisions. Objective: The research aims to propose a clustering scheme to design a risk map of cities for Turkey. Methodology: The unsupervised clustering algorithm suggested dividing the cities of Turkey into clusters, considering health, socio-economic, environmental indicators, and the spread pattern of COVID-19. Results: We found that cities are clustered into five groups while megacity Istanbul alone formed a cluster, three of Turkey's largest cities formed another cluster. Other clusters consist of 19, 26, and 32 cities, respectively. The most important determinants which have predictive power are identified. Conclusion: The suggested clustering method can be a decision support system for policymakers to determine the differences and similarities of cities in quarantine decisions and normalization phases for the following periods of the pandemic. Originality: To the best of our knowledge, this study differs from previous studies because countries were grouped in previous studies only considering the confirmed cases. In this study, cities were clustered in terms of the health, socio-economic, and environmental indicators to make decisions locally. Limitations: The distribution of confirmed cases by age could be added, especially to make decisions about education, but this data is not officially announced.

Introduction: This article is the product of the research "Knowledge management model for decision-making through ontologies for an employment and employability observatory" developed within the ComplexUD Research Group in the Universidad Distrital Francisco José de Caldas between 2018 and 2020. Objective: The objective of this research is the construction of a knowledge management model using ontologies of the actors involved in the employability process. Methodology: The construction of knowledge was carried out through the creation of ontologies, which describe the conceptual components of each actor that participates in employability, since their interaction forms the proposed model. Conclusion: It is observed that representing the actors through ontologies allows the behavior among them to be modeled in a way that is very close to reality, however, it must be taken into account that the components that describe the actors can change over time, for what is necessary a periodic update of the model. Originality: This document proposes original ideas regarding the definition and behavior of the actors identified in the development of the research, if the work of other authors is mentioned throughout the article, it is cited according to the norms established by its publication.

Introduction: The review article is the product of the research on Security in SDN networks and their applications, developed at the District University in 2020, presenting the latest advances, that have been made in security. Problem: The security weaknesses that SDN networks have had, due to being a new architecture. This has not allowed traditional networks to be replaced. Objective: To carry out a review of the state of the art of SDN networks, focusing research on the security of the control layer and its advances. Methodology: The descriptive method is implemented, consulting databases such as Scopus, IEEE and ScienceDirect, using the following search criteria: SDN networks, security in SDN networks, applications with SDN networks and OpenFlow protocol. It is shown as a research sample: the Asian, European and American continents with years of research from 2014 to 2020. Results: Great advances have been made in terms of security for SDN networks, which allows us to see an early solution to the weaknesses that it currently faces. Conclusion: SDN networks will solve all the challenges they face and will be consolidated as a solid and reliable architecture. Originality: an important focus is taken on the security of SDN networks and the great development that has occurred in this regard is evident. Limitations: SDN networks are a new architecture, so their development has been very little and advances in security have been significantly affected.

Introduction: The article is the product of the investigation of the determination of the concentration of particulate matter PM2.5, estimating the influence of temperature and precipitation, developed at the Universidad Libre, Bogotá Headquarters between the years 2018-2019. Problem: Concentrations of particulate matter have increased in recent years in Bogotá, generating a serious environmental problem, concentrations that have been caused by the automotive fleet and industries. Objective: To determine the relationship of the particulate material with the meteorological variables Precipitation and Temperature, and the influence of the contributing sources of PM2.5 in the studied area. Methodology: For the determination of [PM2.5] a WilBur model low volume sampler was used, the meteorological data were obtained from the Bogotá Air Quality Monitoring Network of the Secretary of the Environment. Softwares such as ArcGis, WRPLOT and MiniTab were used for the graphical representation of the results. Results: The average [PM2.5] for dry and wet season was 9.03 and 19.22μg / m3. . For the meteorological variables, a precipitation of 40.4 and 373.6 mm, a temperature of 14.3 and 15.32 ° C, respectively, was obtained. Conclusion: There is a low relationship between meteorological variables and [PM2.5] in both monitoring seasons, however, a behavior of concentrations similar to that found in the literature is evidenced. Originality: PM2.5 sampling in both seasons within the Free University, cataloged as a background area. Limitations: The monitoring time for the year 2018 was in the months of July and August and the year 2019 from March to May.
