AG-CASU : An algorithm to generate irrigation parameters and crop management strategies for the aquacrop model
(2019-05) Pertuz Peralta, Vanessa Paola; Pérez Orozco, Adith Bismarck; Maestre Pérez, Jesus David; Ortiz Iglesias, María Isabel; González Guerrero, Enrique
This paper presents an algorithm to generate the irrigation policies and crop management configuration files for the agroclimatic risk model AquaCrop. The software determines the parameters to be modified by a stochastic method. The AG-CASU algorithm takes account of the limits determined for each variable. The algorithm can be configured to determine the number of scenarios, the number of simulations, the feasibility of each of the parameters, the initial seed file and the compliance with the AquaCrop agroclimatic risk model. In general, the agroclimatic risk models use data and information referring to climate, soil composition, temperature, rainfall, availability of water resources and characteristics of the crops to estimate the productivity of a given crop. The genetic algorithm for calculating fitnness is connected to the AquaCrop simulator, which, given a set of parameters that represent an irrigation policy, generates an estimate of biomass productivity. The algorithm was validated through a case study in special coffee crops of the Sierra Nevada de Santa Marta, Colombia. The proposed algorithm automatically obtains the files corresponding to irrigation policies and cultivation strategies of the AquaCrop model, with coverage of the domain of the variables and with compliance to the AquaCrop software.

A presente investigação procura facilitar o planejamento e o melhoramento de estratégias para a promoção da cultura do empreendimento, ao descrever as diferentes iniciativas desenvolvidas nas Universidades. Para fazer isso, foi realiza-da uma caracterização das estratégias administrativas e didáticas implementadas, e os planos de negócios formulados como trabalho de graduação por estudantes dos programas acadêmicos. A pesquisa é de caráter qualitativo, de tipo descritivo por meio da análise de conteúdo em entrevistas e documentos de três universidades na modalidade presencial no município de Valledupar (Colômbia). Os resultados principais evidenciam como estratégias de gestão, a criação de Unidades do Empreendimento, dependentes das Vice-Reitorias de investigação e extensão, que não são concebidas dentro do Projeto de Educação Institucional e existem sem acordo administrativo. Referente aos serviços prestados, o 66% das universidades sensibiliza, identifica e desenvolve planos de negócios, conseguindo a criação de uma empresa com capital semente do Fundo Empreender, e duas universidades fazem investigações de questões de empreendimento. Como estratégias didáticas de fomentação, são oferecidos cursos disciplinares, eletivos, módulos, palestras, amostras, planos de negócios, convocatórias de ideias e Blogs. Do mesmo foram formulados 173 planos de negócios como trabalho de grau, orientados assim: o 51% para o sector secundário, seguido de um 40% a o sector terciário, e são na sua maioria alinhados com a aposta atual de produção regional: agroindústria. As universidades cumprem as suas funções dentro do ecossistema do empreendimento; a maior limitante é a ausência de alinhamentos específicos para a promoção da cultura do empreendimento a o interior das mesmas.

Intellectual Capital : A comparative view between enterprises and universities
(2018) Pertuz Peralta, Vanessa Paola; Pérez Orozco, Adith Bismarck; Boscan Romero, Neida Coromoto; Bermúdez Rojo, Maribel del Socorro; Solorzano Bastidas, Carlos
This paper analyses the approaches of intellectual capital in enterprises and universities. It aims to the conceptualization, classification, and measurement of intellectual capital, and then it compares both approaches. The research is supported by the theories of Fazlagic, Alama, Molina, Sanchez, Elena and Castrillo, Paździor and Paździor and Bratianu. The study is done through bibliometrics, using a kind of descriptive, documentary research; with a non-experimental, and transversal design. The population is finite and represented by papers, conference proceedings, and thesis published between 2005-2014. To collect the primary data was used the direct observation technique, through concept analysis. We conclude, based on the results, generally, enterprises use the paradigm of fixed capital, focus on relational capital, while in universities the paradigms changed to the dynamic, Newtonian, integrating and transformational intellectual capital, based on human capital. Additionally, that as much as in the universities as in the enterprises the intellectual capital improved the performance of the organization, thus, the revision of the literature states that the results generated by the effective management of the intellectual capital are sustained in the time because of its immaterial nature. Moreover, in the enterprises, the predominant components correspond to the relational capital such as clients, suppliers, strategic alliances and the company reputation in front of the clients, which are essential for the generation of knowledge and the development of innovation.

Modelo de transferencia tecnológica aplicado a una asociación de cafés especiales de la sierra nevada de Santa Marta: Estudio de caso
(Valledupar: Universidad de Santander, 2018, 2018-12-17) Torres Díaz, Juliana-Estefani; Pertuz Peralta, Vanessa Paola; Universidad de Santander
This investigative work aims to specified a technology transfer model adapted to Asoprokia. It is an association of special coffees growers of the Sierra Nevada de Santa Marta. Which will be act as a way to transmit the AG-CASU and AquaCrop software, like an option for the strengthening of the productive units and for all processes involved in it. The designed model can be integrated and applied to other transfers relevant to the needs of the organization. Hence, Technology Transfer will be understood as the process of acquisition, assimilation, transmission (by the Universidad de Santander, headed by the author of this work) and absorption of knowledge, techniques, and tools useful to Asoprokia growers, to generate changes of positive behavior around the actions or management practiced for the production of special coffees. It is important that the Asoprokia community knows these tools through the design of assertive channels where technology information will be passed to all interested parties, and strengthen the ties between science and community. A descriptive and transversal type study was developed, supporting the arguments in different authors, under the case study methodology. Among the techniques for collecting of information we use direct observation and interviewing. This prototype is validated by expert judgment. The result is a three-stage model: 1. Articulation of the organization's planning with technology transfer, 2. Preparation for technology transfer, 3. Evaluation and monitoring of the technology transfer process.

A process innovation based on activities, types and characteristics
(2018) Pertuz Peralta, Vanessa Paola; Pérez Orozco, Adith Bismarck; Boscan Romero, Neida Coromoto
Cystoisospora suis is a protozoan with cosmopolitan distribution and can cause significant economic losses due to yellowish diarrhea and dehydration in suckling piglets. It was carried out an investigation from September 2015 to August 2016 with the aim to determine aspects of the infection dynamics of Cystoisospora suis in suckling piglets raised in pilot farm located at Parish of Güigue, Carlos Arvelo Municipality, Carabobo State, Venezuela. For parasitic determination, 480 fecal samples were collected directly from the rectum in litters (fourty monthly fecal samples) and epidemiological survey was applied for each sampling or survey. Stool samples were cultured in a 2.5% potassium dichromate solution and later processed by flotation-concentration technique, using a NaCL saturated solution enriched with sugar solution (1 L of saturated solution of NaCl + 500 g of sugar). The results indicated that C. suis was present throughout the study period with 52.08% of prevalence in suckling piglets, with biggest values in the second weeks of life. Regarding to sampling month, no statistical significance (P>0.05) was found between the meteorological constants and C. suis prevalence, which could indicate that the environment had no effect on the presence of the protozoan. Data collected from the epidemiological survey were analyzed using a Spearman correlation test, and was determined a significant association (P<0.05) between prevalence and Veterinary presence, protocol N° 3 of disinfection and use of Baycox to 5%. It is concluded that protozoan was present during the study period, with biggest values in suckling piglets with two weeks of life, and no statistical significance was found between the meteorological constants and the prevalence of C. suis, which could indicate that the meteorological conditions recorded during the period studied were optimal for the sporulation process to occur, and therefore to maintain viable oocysts throughout the year.
