Objective: to evaluate in a physicochemical, microbiological and sensory way a sauce and a functional drink based on red bean extract (phaseolus vulgaris) with guava pulp.  Methodology: the work was developed in a pilot plant, which took into account the pulp of fruit and beans of red beans sold in the different supermarkets of the city of Valledupar where representative samples of 5 kilos of guava and 5 kilos of beans to obtain the drink and, based on NTC 659, a factorial design of 22 was applied.  Results: The consistency of the red bean extract sauce with the highest protein content (11.3%) was the attribute of greatest acceptance by the untrained evaluators with 67.3%, and the color was the one with the lowest acceptance with 53.3%. However, in general, the product had a preference of 61%. The flavor of the nectar-like drink with the highest protein content (11%) based on red bean extract and guava extract was the attribute that had the highest percentage of acceptance by the untrained evaluators, with 70.6% , and consistency was the attribute with the lowest percentage of acceptance with 61.3. However, again in a general way, considering all the attributes, the drink had a preference of 64.5%.  Conclusions: the mineral composition (Fe, Na, K, Ca and Mg) both of the bean extract sauce and the drink based on red bean extract and guava extract were valuable contributions, especially in the content of potassium and calcium, which contribute to maintaining the muscular and gastric stability of the human being.

Objective: implementation of an alternative of attendance control to classes, by means of fingerprint biometrics in the University Foundation UNINPAHU.  Methodology: through the application of surveys and perception to the students, relevant data were obtained and, according to these, an analysis and diagnosis was made that showed the need to use technology to evolve from the paper formats to the record of attendance through the footprint. fingerprint. Results: a software application was identified, designed and developed to take control by means of biometrics, which evidenced an optimization of the process, a decrease in the use of paper, centralization of data and the availability of information online, to support making administrative and academic decisions.  Conclusions: the investigation determined the perception of the students of the University on the process of attendance to class and the importance of changing to other methodologies, that reduce the costs of the use of stationery, perceptions that were considered in the present investigation and led to the product final.

Objective: to analyze neotectónicamente the fault of the dry river, In the city of Valledupar.  Methodology: to determine if the recent seismic activity is related to this failure, an identification, classification and analysis of morphotectonic traits of the trace of the same in recent deposits was made. Making use of aerial photographs and satellite images.  Results: analysis of the different morphotectonic expressions in the recent deposits, which allowed to outline the fault line on the quaternary, and in the field phase some kinematic characteristics were determined, checking the morphological changes produced, such as deflated rivers, lagoon of flood, springs and discontinuities as diaclases.  Conclusions: these changes indicated that Falla Rio Seco has recent activity and is affecting Quaternary deposits. In addition, it was established that the fault continues with its NEE orientation to the Cesar-Ranchería basin. It was concluded that the Falla Río Seco has recent activity and constitutes a significant threat to the city.

Objective: to identify the physical-chemical characteristics of the soil, as well as to relate them to their structural behavior and environmental conditions, in order to serve as an input in soil environmental diagnostics.  Methodology: the developed method started from the extraction of superficial samples of soils in a random way and with depths less than 0.3 m. The samples were transported to the laboratory, where they were tested for natural moisture, organic matter, soil classification and unit weight. Then a statistical analysis was performed.  Results and conclusions: according to the group of identified, cohesive and granular soils, these present conditions that can affect environmental behaviors and susceptibility in aspects of fertility or eventual cases of contamination.

Objective: to carry out an analysis of the role that human resource management plays within an organization that seeks competitiveness. Results and conclusions: the human talent of a company is the most valuable asset of the same, which is why a good human talent management should be characterized by enhancing human capital for the benefit of the objectives, visualizing employees as partners for that through their talents develop strategies, rather than through administrative actions generating a competitive advantage in the market and positively impacting the various programs and policies, as well as the financial statements of the company.

Objective: this article exposes the relationship between the motivation of employees and the achievement of results within an organization, highlighting the importance of the leader in the framework of the intrinsic and extrinsic nature of motivation.  Methodology: study the role of satisfaction of needs in motivation according to the theory of self-determination, and how, in the opposite way, management can discourage performance.  Results and conclusions: a documentary review was carried out under the focus of qualitative research, focused on the management of the will as a focus of investment in the various scenarios for organizations and as a critical factor in the results.

Objective: The present investigation is focused on physically and mechanically characterizing multiple Samples of the coal waste belonging to the municipality of Lenguazaque (Cundinamarca), with the purpose of identifying the possible use of this material in engineering, especially in road infrastructure works. Methodology: Normative foundations were used, techniques that generated results and information provided by the Ministry of Mines who indicate that the contribution of mining to the growth of the country's economy has shown high growth in recent years, which contrasts with the negative effect that this practice entails on the environment, taking into account that in the extraction of coal there are solid residues resulting from the exploitation of this mineral, these residues are called "sterile coal", which are mostly removed from the carbon so as not to affect the energy potential of the product. Results and conclusions: The results of the research are encouraging since its characteristics place the material as an alternative for the construction of low traffic road structures.

Objective: To describe the methodology for determining the feasibility of producing electricity through the use of wind energy, taking into account the data of the wind resource and the use of a low-power commercial wind turbine to carry out the energy conversion. Methodology: For this study the data supplied by the meteorological station of the Camilo Daza airport in the city of Cúcuta was evaluated over a period of 5 years, including from the year 2010 - 2014. Results: The WINDSPOT 7.5 commercial wind turbine was selected kW to establish the production of energy based on the data supplied by the station. Conclusion: With the analysis of the data provided, it was determined that the implementation of a wind station in the aforesaid area is not feasible given the fact that  wind speeds are not within the recommended range, which must be higher than 5 m / s.

Objective: To develop the capacity indexes of a process for a polynomial profile in a sauce manufacturing company where it is intended to explain the approaches that are acquired through the application of a statistical control, to improve the productive processes, reducing costs and offering competitive products in the market. Methodology: The research uses quality techniques, applying methods, analysis, control of variables and characteristics of the product, which applied in combination according to this research form the statistical control of the process. Results: Based on the limits of specifications, a linear profile was elaborated for the independent variables, establishing a same polynomial linear profile to correlate the study variables (° brix and chloride) for the elaboration of sauces for meats. Conclusions: This study aims to develop better control, which will help decision making in an effective way in terms of the adjustments to be considered in each process, establishing methods, goals and an exceptional means of verifying the behavior of the system.
