Crawford-Visbal, Joseph Livingston | 2021

La difusión del Internet se ha convertido en una política central de los países en desarrollo. Los investigadores de campos como las ciencias políticas y económicas identifican que esta conectividad es clave como un motor del desarrollo económico y la innovación (Grazzi & Vergara, 2014). La literatura científica está fragmentada y escasa en cuanto a una zona en desarrollo como lo es Latinoamérica, pero a pesar de esto ha visto un resurgir académico durante los inicios del siglo XXI. Es innegable que las Tecnologías enfocadas en la Información y la Comunicación-TIC han cambiado radicalmente la manera como operan diversos sectores de la sociedad, particularmente la manera como los negocios son realizados.

A mathematical model for the optimization of the non-metallic mining supply chain in the mining district of Calamarí-Sucre (Colombia)
...
Ospina-Mateus, Holman | 2020

This article presents a mathematical model of the Supply chain of non-metallic mining. The model considers uncertainty scenarios in materials, elements for capacity planning in a multilevel chain and with multiple products. The mathematical model is collaborative and maximizes the profits of the actors in the supply chain. The model is implemented in Calamarí-Sucre mining district (Colombia). The scenario is applied to the extraction, processing, storage, and distribution of limestone. To solve the model, the GAMS software was used through libraries of relaxed mixed nonlinear programming - RMINLP and the DICOPT solver. The results indicate that the greatest benefits occur in a scenario of the high provision of raw materials. The equity in the economic benefits show a dynamics of vertical integration in the sector. The model applied to non-metallic mining complexes helps determine optimal strategies and decisions in different echelons.

Acreditación institucional y su incidencia en la cobertura en educación superior en el Caribe Colombiano
...
Hernández Saams, Carmen | 2017

The purpose of this research is to determine the incidence of institutional accreditation in the extension of coverage in Higher Education in the Colombian Caribbean. Even though coverage in the Colombian Caribbean has increased in recent decades, it is still low compared to the national average. It is evident that the emergence of the Accreditation of Higher Education Institutions has generated a better positioning for the Institutions of the Colombian Caribbean region. The methodology is approached from the positivist paradigm of quantitative cutting under a type of descriptive research, non-experimental design. It was taken from a population composed of 33 accredited educational institutions in the country, a sample composed of 7 accredited Higher Education Institutions and with coverage in the four departments belonging to the Colombian Caribbean: Barranquilla, Cartagena, Santa Marta and the San Andres Archipelago, Providencia and Santa Catalina. The results are determined based on statistics related to coverage and quality of the Higher Education Institutions accredited and analyzed in such a way that they allow to determine how the processes of institutional accreditation have influenced the expansion of the Higher Education coverage in the Colombian Caribbean. With the work developed and developed, relevant information on the incidence of accreditation in coverage is offered to the Colombian Caribbean education system.

Actinic keratosis in Colombia: first approaches
...
Castillo Molina, David | 2021-09-01

Introduction: Actinic keratoses (AK) are preneoplastic lesions secondary to chronic sun exposure, whose risk of becoming malignancy is greater than 20%. Prevalence studies of AK are uncommon. Here we describe clinical and epidemiologic characteristics of patients with AK assessed in a dermatology center from Bogota, Colombia. Materials and methods: A descriptive retrospective study was performed. Data were collected from January 2014 to July 2020. These included age at diagnosis, sex, occupation according sun exposure (inside-job, outside-job and inside/outside-job), dwelling place, Fitzpatrick phototype, anatomical location, progression time, skin cancer (SC) history and development. We used relative and absolute frequencies to describe patients. Data analysis was performed in Epi Info. Results: Of 820 patients, 61% were women. Mean age was 66 years (SD ± 12). Of all patients, 5.4 out of 10 were phototype III. The median progression time was 34 months. The 57% (n = 468) of patients had inside-jobs. The face was the most commonly affected area in 750 patients (91%). History of SC was observed in 27% of patients, and 2.56% (n = 21) developed SC, from which five cases were squamous cell carcinoma. Conclusion: Actinic keratosis may evolve into SC in a considerable percentage conversely to our study. We found that most of the patients with AK had an inside-job, which might reinforce the impact of genetic load, artificial lights exposure and the effect of protection barriers on AK development. Further studies are needed to improve clinical characteristics knowledge associated with AK.

Adaptation of an effective school-based sexual health promotion program for youth in Colombia
...
Morales, Alexandra | 2019-01-05

Rationale: Given the disproportionate impact of HIV and STIs among youth in Latin America, there is a compelling need for effective sex education programs. In particular, Colombia lacks a nationally standardized youth sex education program, despite the fact that 15 to 24-year-olds accounted for the highest incidence and prevalence rates of HIV and STIs in the nation. In an attempt to fill this void, our team adapted COMPAS, a Spanish school-based sexual health promotion intervention, for Colombian adolescents. Objective: This study describes the adaptation process that resulted in a modified version of COMPAS for youth in Colombia. Method: We employed a systematic cultural adaptation process utilizing a mixed methods approach, including intervention adaptation sessions with 100 young adolescents aged 15–19. The process included six steps: 1) consulting international researchers and community stakeholders; 2) capturing the lived experiences of a diverse sample of colombian youth; 3) identifying priorities and areas in need of improvement; 4) integrating the social cognitive theory, information-motivation-behavioral skills model, and an ecological framework for colombian youth; 5) adapting intervention content, activities, and materials; and 6) quantitative evaluation of COMPAS by Colombian youth. Results: The adapted intervention incorporates elements common to effective youth sex education interventions, including: a solid theoretical foundation, sexual communication skills and social support for protection, and guidance on how to utilize available cultural- and linguistic-appropriate services. In addition, the adapted intervention incorporates cultural and linguistic appropriate content, including an emphasis on tackling machismo to promote risk reduction behaviors. Conclusions: The systematic adaptation approach to sexual health intervention for youth can be employed by researchers and community stakeholders in low-resource settings for the promotion of health wellness, linkage to care, and STI and unplanned pregnancy prevention for youth.

Adherence to long-acting reversible contraceptive methods in low- income young women from the caribbean region of Colombia
...
Salcedo Mejía, F. | 2021

Adolescent pregnancies are more likely to occur in poor communities, commonly driven by lack of education and employment opportunities. We aimed to estimate the subdermal implant discontinuation rate and to establish the factors associated with the discontinuation of long-acting reversible contraceptive (LARC) methods in a cohort of poor women in the Caribbean region of Colombia. A retrospective cohort study of LARC method use through review of administrative record data was conducted. A population of 2,192 adolescents and young women between 10-24 years old enrolled in the “SER JOVEN” program and who received subdermal implants between 2015-2018 was considered for eligibility. This program is for young people affiliated to a health care company in the Caribbean region of Colombia. We realized a follow-up time-person of the retrospective cohort, and we estimated the incidence of discontinuation of the subdermal implant at six months, one year, two years, and three years. Kaplan-Meier estimator for survival curves, and Cox proportional hazard model were used to ascertain factors associated with method discontinuation risk. A p-value <0.050 was considered significant. A total of 2,192 women were selected with a mean (standard deviation -SD) age of 19.4 (2.8) years and a mean duration of use of subdermal implant of 2.6 (0.8) years. We estimated the subdermal implant discontinuation rate at six months in 0.7% [CI95% 0.3-1.1], a year later in 1.5% [CI95% 1-2], two years later in 2.1% [CI95% 1.5-2.7] and finally at three years in 2.2% [CI95% 1.6-2.8]. Women who stated they have children at baseline were about 70% less risk to discontinue subdermal implants (HR: 0.3 [CI95% 0.1 – 0.8]). Adolescent pregnancy is a public health problem, and it is an important cause of poverty and illness. Then, the use of subdermal implants is an effective alternative to prevent unintended pregnancies.

Mercado Hernández, Ana | 2021

La educación siempre ha tenido sus propios retos, y aunque haga parte de un engranaje en el que se forjan o se construyen los individuos, y del cual también participan otros factores como lo social, cultural, económico y político, es indiscutible que al proceso educativo le son propias unas deficiencias como también unas dificultades, logros y valoraciones. Con el paso del tiempo la producción teórica, la pedagogía, la didáctica y las dinámicas en la educación se han reinventado y especializado, abriendo lugar a debates importantes, como también a la incorporación de otras disciplinas como la psicopedagogía y la neuropedagogía que han apoyado en métodos y valoraciones para la enseñanza. Es esta una trayectoria de siglos que bien podría ir desde Jean-Jacques Rousseau hasta María Montessori, Jean Piaget o Lev Vygotsky, Comenio y la tradición griega ilustrada centrada en la pregunta socrática.

Contreras Salinas, Jheison Alberto | 2020-06-08

Energy production is constantly facing major challenges today, because despite initiatives to promote the insertion of renewable energy, electricity consumption has shown considerable growth in recent years. In order to use an instrument that facilitates forecasts and predictive processes for the design of strategic plans associated with energy management, the application of the Holt Method is proposed using data on electricity demand in Colombia, GDP per capita and industrial value added, making an analysis of the last 10 years, based on figures from the World Bank. The final results predict that energy consumption for the period 2018-2020 will be between 66,231 GWk and 66,885 GWk.

Analysis of the role of process innovation on export propensity in KIBS and non-KIBS firms in Colombia
...
Moreno-Gómez, Jorge | 2020

The purpose of this paper is to analyze the role of the process innovation on export propensity in knowledge-intensive business services (KIBS) firms and non-KIBS firms in Colombia. For the empirical application, the authors use a unique primary data set drawn from the Global Competitiveness Project (GCP: www.gcp.org) that includes information for 57 Colombian KIBS for 2019. The authors use a binary choice model to test the proposed hypotheses on the relevance of KIBS and process innovation in explaining export propensity. The results showed a positive relationship between KIBS and business size with an export propensity, but this relationship is non-meaningful. Also, the findings showed a negative and non-significant relationship between a process innovation and business age with the probability to export. On the other hand, the evidence state that KIBS firms encourage the relationship between propensity to export and process innovation, which is to say that they are highly effective to increase the propensity to export. Finally, the industry increases the probability of export propensity. This study offers a new insight relating to KIBS, process innovation and their contribution to increasing export propensity. The findings of this paper offer relevant information to government policymakers to design strategies that promote export activity in Colombia.

This research deals with a comparative analysis of the benefits and employee tax liabilities in Colombia and Mexico for the 2015 analysis, in which the impact that taxation of these countries in the annual declaration of income tax is studied that year, in order to identify similarities and differences from a tax point of view. Additionally they disclosed what are the benefits and obligations held by the employee in both countries by 2015. In effect, each tax system pursues ends in common; only differ from the control mechanisms used in each country. However, the situation is changing with the many unfair tax reforms implemented year after year, although it is worth mentioning that they are justified. However, they trigger certain economic effects that affect the fulfillment of the substantial tax obligation, even though it implies an economic sacrifice for the taxpayer, and thus provokes certain reactions, which lead him to devise forms of evasion and fiscal fraud that in the last affect the economy of a country in general. This study was carried out considering the mixed methodology, and as a research strategy the case study was used, which allows to understand the dynamics present in singular contexts and to obtain data from different sources, as well as to deepen in concrete and to obtain broader knowledge on the Phenomenon studied. The results of the investigation showed that despite the complexity of the Colombian tax system; Employees in Colombia have more tax benefits than those employed in Mexico, because the ISR Law in Colombia greatly stimulates these taxpayers by reducing their tax burden.

Assessment Of Human Health Risk Associated With Methylmercury In The Imported Fish Marketed In The Caribbean
...
Fuentes Gándara, Fabio Armando | 2018-08

The decline in marine and freshwaters catches in recent years in Colombia has led to a change in dietary habits, with an increase in the purchase and consumption of imported fish. This is of particular concern as fish are sometimes caught in mercury-contaminated waters, and are subsequently sold canned or uncanned. In addition, canned tuna has received little attention as it is widely assumed that concentrations are low. In this study, total mercury (THg) and methylmercury (MeHg) concentrations were evaluated in three imported fish species marketed in Colombia, Prochilodus lineatus, Prochilodus reticulatus, and Pangasianodon hypophthalmus, plus four brands of canned tuna and one of sardines. One brand of tuna showed the highest mean concentrations of THg (0.543 ± 0.237 μg/g, wet weight, ww) and MeHg (0.518 ± 0.337 μg/g ww), while concentrations in P. hypophthalmus were approximately 30 times lower (≈0.02 µg/g ww). The estimated weekly intake (EWI) in children was above the provisional tolerable weekly intake (PTWI) of MeHg established by the Joint FAO/World Health Organization (WHO) Expert Committee on Food Additives (JECFA) in 2007, 1.6 μg/kg body weight (bw) per week, for all the canned tuna brands. Values for adults were below PTWI, whereas for women of childbearing age, values were above PTWI only for brand D of canned tuna. The estimate of the potential risk indicated that MeHg levels in canned tuna can generate negative effects in vulnerable groups, while the EWI of fresh fish did not pose a threat to the general population. Therefore, establishing strategies to address the high consumption of canned tuna, and continuous monitoring to control commercial food, are recommended to decrease Hg exposure.

Association between exposure/adherence to a cardiovascular risk management program and the incidence and mortality of cardiovascular events in the Caribbean region of Colombia
...
Salcedo Mejía, F. E. | 2019

Objectives: To establish the association between the exposure to a cardiovascular risk management program [“De Todo Corazon (DTC)” program in Mutual SER-EPS] and the reduction of incidence and mortality by cardiovascular events (CVE: AMI, Stroke, congestive heart failure). Methods: Cohort study that compared the occurrence of CVE among patients over 18 years of age exposed and non-exposed to the DTC program (N = 113,277). Enrolled patients in the DTC program between June 2015 and June 2017 were considered as the exposed population and patients enrolled in the DTC program between July 2017 and July 2018 were considered as the unexposed population. Patients who achieved clinical goals (blood pressure, 140/90 mmHg, HbA1c, 7.5% and LDL cholesterol, 100 mg/dl) were considered adherent to the DTC program. Incidence and mortality rates were compared and Incidence rate ratio (IRR) was used to evaluate the effect of the program. A Poisson regression model was used to assess the association between exposure to the program and CVE adjusting by socio-demographic characteristics and clinical goals. Results: The incidence of CVE in exposed and unexposed patients was 6.8 and 9.5 per 1.000 persons per year, respectively [IRR of 0.72 (95% CI 0.60-0.87)]. Mortality associated to CVE in exposed and unexposed patients was 0.46 and 0.56 per 1.000 persons per year, respectively [IRR 0.82 (95% CI 0.40-1.95)]. When adjusting the estimation by age, sex and achievement of clinical goals, a lower incidence rate of CVE among patients who were adherent to the program was observed [IRR = 0.62 (CI 95% 0.46 - 0.86)]. Conclusions: Exposure to the DTC program significantly decreased the incidence and mortality CVE by 28% and 18%, respectively. Adherence to the DTC program significantly decreased the incidence of CVE by 38%.

La modalidad de vender “tinto” de forma ambulante no solo se expresa caminando, ya que existen algunas personas, en especial mujeres y ancianos que, a diferencia de los hombres jóvenes, utilizan pequeños carritos para transportar los termos que contienen el tinto y las aromáticas a vender. En la mayoría de los casos estos carritos a los que se hace referencia son coches para bebé o carros de supermercado en desuso con aditamentos, que al modificarlos sirven para colocar de manera segura los termos, suministrándole a estas personas una gran eficacia con relación al transporte de sus implementos de trabajo.
