Psicoterapia de una adolescente Puntualizaciones en el caso de A*
Mesa,Ana María; Orduz,Luis Fernando;
Revista Colombiana de Psiquiatría , 2011,
Abstract: introduction: the aim of this clinical case is to analyze the transformations in object relations and narcissism of a teenager who began psychotherapeutic treatment because of conflicts in the constitution of her sexual identity. method: the treatment was one of support and expression with an open time frame and a weekly session. development: the analysis of the process allowed us to see how object representations and those of the self were gradually integrated, and contributed positively in her dealing with her adolescent conflicts and especially the one related to her sexual identity. finally, we suggest the hypothesis that the treatment's positive results could be in connection with the therapeutic attitude of “yes-memory and yes-wish”, which would be an interesting matter for discussion in relation to the use of psychotherapeutic techniques with adolescents.
Psicoterapia de una adolescente Puntualizaciones en el caso de A* Psychotherapy of an Adolescent. Remarks on 'A' Case
Ana María Mesa,Luis Fernando Orduz
Revista Colombiana de Psiquiatría , 2011,
Abstract: Introducción: El presente caso clínico tiene como objetivo analizar las transformaciones en las relaciones objetales y en el narcisismo de una adolescente que inició su tratamiento psicoterapéutico por conflictos en la constitución de su identidad sexual. Método: Tratamiento de soporte y expresión, con un encuadre de tiempo abierto y una frecuencia de una sesión semanal. Desarrollo: El análisis del proceso permitió ver cómo tanto las representaciones objetales como de sí misma se fueron integrando e incidieron positivamente en el enfrentamiento de los conflictos propios de su adolescencia, especialmente de su identidad sexual. Finalmente, se plantea la hipótesis de que los resultados positivos del tratamiento podrían estar en relación con la actitud de “sí memoria y sí deseo” de la terapeuta, lo cual sería de interés en la reflexión sobre la técnica psicoterapéutica con adolescentes.

Lecciones del programa de prevención temprana de la violencia, Medellín, Colombia
Duque,Luis Fernando; Orduz,José Fernando; Sandoval,Juan de Jesús; Caicedo,Beatriz Elena; Klevens,Joanne;
Revista Panamericana de Salud Pública , 2007, DOI: 10.1590/S1020-49892007000100003
Abstract: objective: to describe the components and development of the early prevention of violence program in the city of medellín, colombia, and to evaluate the results of its first phase, three years after implementation. methods: a before (2001) and after (2004) study of four variables-direct aggression, indirect aggression, prosocial behavior, and scholastic achievement-was conducted among a convenience sample of 339 program participants and their families. results: several program benefits were noted. decreases in both direct and indirect aggression were observed, though the latter was reduced only in girls and in those over 12 years old. prosocial behavior increased among children of all ages and both genders, including those who exhibited low levels of prosocial behavior in 2001. in addition, improved school performance was seen in the group as a whole. results may have been affected by some changes to the prevention program?s implementation and by the dangerous nature of the neighborhood, which limited the home visits. conclusions: the program seems to be an effective intervention for highly aggressive children, among whom a decline in direct aggression was observed. it also offers preventive benefits, as evidenced by the rise of prosocial behaviors in less aggressive children.

Evaluation of Contact Pressure in Bending under Tension Test by a Pressure Sensitive Film  [PDF]
Luis Fernando Folle, Lirio Schaeffer
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2016, DOI: 10.4236/jsemat.2016.64018
Abstract: The contact pressure acting on the sheet/tools interface has been studied because of growing the concern about the wear of tools. Recent studies make use of numerical simulation software to evaluate and correlate this pressure with the friction and wear generated. Since there are many studies that determine the coefficient of friction in sheet metal forming by bending under tension (BUT) test, the contact pressure between the pin and the sheet was measured using a film that has the ability to record the applied pressure. The vertical force applied to pin was also measured. The results indicate that the vertical force is more accurate to set the contact pressure that using equations predetermined. It was also observed that the contact area between the sheet and the pin is always smaller than the area calculated geometrically. The friction coefficient was determined for the BUT test through several equations proposed by various authors in order to check if there is much variation between the results. It was observed that the friction coefficient showed little variation for each equation, and each one can be used. The material used was the commercially pure aluminum, alloy Al1100.
Treatment of Bilateral Recurrent Dislocation of Hip Pros-thesis with Malpositioned Well-Fixed Shell: A Case Report  [PDF]
Fernando Judas, Luis Maximino, Francisco Lucas
Open Journal of Orthopedics (OJO) , 2013, DOI: 10.4236/ojo.2013.33031
Abstract: Dislocations of total hip prostheses cause pain and patient dissatisfaction. Recurrent dislocations are difficult to treat mainly when the acetabular metal shell is well-fixed. The purpose of this article was to describe the surgical technique used for the treatment of a bilateral recurrent posterior dislocation after a cementless total hip prosthesis, caused by excessive inclination of acetabular components, in a 72-year-old patient. On both sides, acetabular metal shell, porouscoated, was well-fixed. Revision of the entire acetabular component could be an appropriate therapeutic option because it was malpositioned. Nevertheless, a conservative operation was performed. The metal shell was left in situ and the preexisting polyethylene liner was removed and replaced by a new undersized cross-linked polyethylene liner, then, cemented into the shell and properly oriented. An acetabular cemented augmentation reinforced by 3 cortical screws was associated with the reconstruction. This report suggests that cementation of new liner into a malpositioned well- fixed metal shell associated with an acetabular cemented augmentation is a simple and safe technique for the management of recurrent hip dislocation, for elderly patients in which it is advisable to avoid a major revision hip surgery by medical comorbidities. Nonetheless, further studies with medium-and long-term follow-up are needed to validate this technique.
Structural Patterns of Immunoreactivity to Cytokeratin 18 in Normal Prostate and Benign Prostate Hyperplasia: Global and Local Differences  [PDF]
Luis Santamaría, Ildefonso Ingelmo, Fernando Teba
Open Journal of Pathology (OJPathology) , 2017, DOI: 10.4236/ojpathology.2017.72004
Abstract: Background: Benign prostate hyperplasia (BPH) is the most common benign disease of the human prostate. The comparison between global versus local changes in spatial patterns of pathological lesions provoked a growing interest in some fields such as neuropathology. To date, there is little data on this subject in prostatic pathology. Given the interest of local parameters to distinguish between normal and pathological structures, the present study will apply first and second order stereological tools to find out if the cytokeratin18 (ck18) immunoexpression shows relevant local changes in BPH compared to normal prostate, independently if global estimates were similar in both groups. Methods: To verify if the global and local changes in immuno-expression of ck18 are relevant to ascertain differences between normal (CTR) and BPH cases, the following parameters will be applied: Volume fraction of epithelium immunostained for ck18 (VV ck18), both in global and local estimates; dispersion indices of VV ck18; estimates of local variance of VV ck18 (positional and of scale) using wavelet analysis; and lacunarity analysis to measure the tissue heterogeneity. Then, the set of values from the parameters studied that show significant differences between CTR and BPH will be employed to perform stepwise linear discriminant analyses to determine if locally estimated parameters were able to classify accurately the cases in CTR and BPH groups. Results and Conclusions: The findings of the present study indicate that changes in the expression of ck18 by the hyperplastic prostatic epithelium are not homogeneous. This limits the use of a single biopsy based markers to predict biological behavior in BPH. On the other hand, the local changes in the expression of ck18 are more evident in terms of VV ck18 and its local variability, whereas other parameters that are useful in other pathologies, such as lacunarity, are less relevant In prostatic hyperplasia.
REGIONAL POLICY AND INDUSTRIAL LOCATION DECISIONS
Luis Fernando Lanaspa,Fernando Sanz
Investigaciones Económicas , 2004,
Abstract: In this paper we analyse whether di erent infrastructures a ect the location decisions of economic agents. Taking the model in Martin and Rogers (1995), a complete range of infrastructure classes that a region can have is considered. We consider domestic, international transport, international export and international import infrastructures. The principal conclusion is that the optimal regional policy that attracts industrial location is the one that improves domestic and international export infrastructures. Superior domestic and export infrastructures also increase welfare.
La dinámica poblacional del Socorro, San Gil y Barichara entre 1.778 y 1.837

Historia 2.0 : Conocimiento Histórico en Clave Digital , 2012,
Abstract: Resumen Este trabajo se centra en la descripción de los procesos demográficos en las tres poblaciones más numerosas de la Provincia del Socorro, a finales del siglo XVIII e inicios del siglo XIX. Los comportamientos estacionales se vieron afectados por los ciclos climáticos (defunciones), de cosechas (concepciones) y por las prescripciones de la Iglesia Católica (matrimonios). Las epidemias de viruela afectaron constantemente a la región presentándose cada 15 a os en promedio. Se pudo establecer que la movilidad de las personas fue de cierta importancia dentro de los límites de la Provincia. Se apreciaron flujos considerables de personas que llegaban desde las Provincias vecinas del sur y en menor cuantía desde el norte y el este. Esto se confirmó mediante el análisis de larga duración (200 a os) en donde se apreció que el crecimiento vegetativo de la población era dispar frente a los datos de los censos, llevándonos a concluir que la influencia de las migraciones fue fuerte pero no posible de medir con las fuentes disponibles. Se pudo concluir que la independencia política no afectó los procesos registrados en las estadísticas vitales. Mientras que factores como las epidemias, sucesos climáticos o migraciones fueron determinantes y llevaron a cambios en las tendencias. Palabras Clave: Población, Demografía Histórica, Series Estadísticas, Migración, Epidemias Abstract This work is focused on the demographic processes of the three most populous towns of El Socorro's Province at the end of the XVIII century and at the beginning of the XIX century. The seasonal behaviors were affected by climatic cycles (deaths), crops (conceptions) and the Catholic Church’s principles (marriages). Epidemics of smallpox constantly affected the region, occurring on average every 15 years. It was possible to establish that migration inside the Province’s boundaries was of certain importance. In addition, considerable migration patterns from neighboring Provinces in the south and to a lesser degree from the north and east were observed. This was confirmed by an analysis covering 200 years which indicated that the population's vegetative growth deviated from census data, leading to the conclusion that the influence of migrations was strong but immeasurable from our sources. According to the analysis conducted, it could be concluded that political independence did not affect the processes registered in the vital statistics, while factors like epidemics, climatic events or migrations were decisive and induced changes in the tendencies of the aforementioned processes.
