Authors: Penagos Granada Edward Fabián , López Echeverry Ana María , Villa Sánchez Paula Andrea 
Published: March 2018

During 2015 and 2016, in Pereira (Colombia) a training project addressed to public entities officials was carried out in areas related with: law on transparency, ISO 27001 and database reporting, though theoretical and practical sessions. As a result, a local researching group developed a set of documents with relevant and updated information on each topic. So, officials can use them as implementation guides in their respective institutions. This paper describes how the training sessions was developed. Finally, the results of the project are presented in a positive way, taking as a reference both an initial scenario and final scenario of greater complexity.
Gestión de centros: algunas reflexiones y aportes
Authors: Cruz Cárdenas Ruth E. 
Published: March 2018

Cuando nos referimos a centros educativos, lo hacemos, a veces, destacando algunas de sus características; así, podemos decir que uno atiende especialmente la formación de la persona; este otro otorga status al que asiste a él; aquel es muy exigente a la hora de evaluar a sus alumnos y así podríamos continuar dando ejemplos de cómo se identifica una institución educativa en la comunidad. Al entrar por primera vez a un centro se reciben “mensajes” sutiles, a través de la percepción de actitudes, de ambientes percibidos, de expresiones, de presencias o de ausencias, que permiten captar un clima, una cultura, pautas, valores, prioridades institucionales. Esto tiene mucho que ver con el proyecto educativo, con el curriculum institucional, explicitado o no, pero también con el estilo de gestión. La gestión está hoy en la agenda de los Directivos de instituciones educativas, en el discurso de muchos, en la currícula de las instituciones de formación de recursos; en una palabra, está en la mira. La gestión se ha constituido en un tema central, sustantivo a la hora de pensar en el cambio orientado a mejorar los niveles de calidad. Esto ocurre en nuestro ámbito, con más énfasis en los últimos años.
Enseñanza a distancia y educación a distancia: ¿de qué estamos hablando?
Authors: Lorenzo Enrique 
Published: March 2018

El propósito del presente artículo es discutir y analizar los usos y significados que las frases "educación a distancia" y "enseñanza a distancia" tienen en el discurso pedagógico contemporáneo. Partimos del supuesto que con frecuencia estas frases se utilizan como equivalentes, permitiendo esto la fusión de objetos de estudio distintos. En el ámbito de la educación presencial, desde hace varios siglos, se han señalado las diferencias entre "educación" y "enseñanza" y esto ha permitido el desarrollo de referentes teóricos que facilitan el estudio y análisis de situaciones prácticas. La fusión, o confusión, que se manifiesta en el terreno de la educación no presencial, parece ser un tema poco relevante a juzgar por la escasa reflexión que hay sobre este tópico. No obstante, pensamos que es buen momento para iniciar ese proceso de construcción. Es por eso que hoy acercamos estas breves reflexiones sobre el tema en cuestión.

Aims: To evaluate the effect of the chlorhexidine (CHX) incorporation and the storage time on the mechanical properties of glass ionomer cements (GICs). Methods: The following GICs were evaluated: Ketac Molar Easymix (KM), Vidrion R (VR) and Vitromolar (VM), containing or not CHX. GIC liquid was modified by adding 1.25 % CHX digluconate and then manipulated with the power and placed into the stainless steel cylindrical or bar-shaped molds. GICs specimens were stored into water for 1, 7 and 28 days. After these periods, specimens were submitted to flexural, diametral tensile and compressive strength tests, according to ISO standards. Data from mechanical tests were statistically analyzed using 2-way ANOVA and Tukey tests. Results: Overall, the storage time did not influence any of the mechanical properties of the GICs tested. In contrast, the inclusion of CHX reduced significantly these properties for all GICs tested. KM presented the highest values of compressive strength for all storage times. KM + 1.25% CHX had lower compressive strength results than KM, however, it showed similar results when compared to another GICs without CHX. Conclusions: The presence of chlorhexidine, independent of the storage time, interfered on the mechanical characteristics of GIC.

AIM: The aim was to compare the immunoexpression of extracellular matrix proteins in squamous cell carcinomas of tongue (SCCTo) and lower lip (SCCLi). METHODS: Eleven SCCTo and 11 SCCLi were selected and examined according to Bryne’s method (1998). For immunohistochemical study utilized antibodies to fibronectin, tenascin and type I collagen. Histopathologic and immunohistochemical analysis were performed on the tumor invasive front. RESULTS: All SCCTo were classified in high score malignant grade and all SCCLi in lower score. Fibronectin showed strong immunorreactivity in the peritumoral basement membrane (BM) in 91% of SCCTo and all cases of SCCLi, while in the tumor stroma (TS) all cases of SCCTo and SCCLi had strong intensity. Tenascin had strong expression in BM of 91% cases of SCCTo and 63.4% of SCCLi and in TS had strong expression in 91% cases of SCCTo and 54.6% of SCCLi. Type I collagen demonstrated weak immunoreactivity in the TS of 72.7% cases of SCCTo and 63.4% of SCCLi. CONCLUSION: These results may suggest that the strong expression of fibronectin and tenascin proteins and the weak expression of type I collagen could play a role in the invasive process of oral SCC.

Aim: The purpose of this investigation was to document the reasons for placement, and replacement of crowns and fixed partial denture in a Nigerian Teaching Hospital. Methods: a retrospective review of patients that had advanced conservative procedures. A data collection form was used to gather the relevant information from the patients’ case notes. Section A sought information on age , gender, educational level, patients’ occupation etc. Section B recorded information on tooth/teeth involved, reason for fabrication of prosthesis and material used. Results: Three hundred and twenty six had 398 crowns while 23 patients received bridges. Patients’ ages ranged from 16-85 years with a mean of 47.7± 17.2years and a male to female ratio of 1:1.3. Thirty five percent of the crowned teeth were in the upper right quadrant, followed by the upper left quadrant with 29.4%. Upper right central incisors were the most frequently (15.6%) crowned teeth. Endodontics and esthetics were the most common reasons for initial crown placement and replacement respectively. About 60% of bridges fabricated were new, while 22.2% of replaced bridges were due to fracture of porcelain and unacceptable marginal adaptation. Conclusion: Endodontics and esthetics were the most common reasons for initial crown placement and replacement.

<p>La presente investigación tiene como propósito analizar las propiedades psicométricas de la Escala de Satisfacción y Frustración de las Necesidades Psicológicas Básicas de Autonomía, Competencia y Relación (ESFNPB) identificadas por la teoría de la autodeterminación (Deci &amp; Ryan, 2000b), en una muestra de 297 estudiantes universitarios de distintas facultades y carreras pertenecientes a una universidad Chilena. Para lograr el objetivo, mediante un estudio psicométrico por procedimientos confirmatorios, se realizó un análisis factorial confirmatorio (AFC), analizando la propuesta de seis factores realizada por Chen et al. (2015) y se evaluó la consistencia interna de la escala mediante el Alfa ordinal. Los resultados obtenidos con la muestra de estudiantes universitarios indican una buena consistencia interna, alfa = 0.90 y 0.86 para satisfacción y frustración de las necesidades psicológicas, así mismo los resultados del análisis factorial confirmatorio mostraron un ajuste adecuado del modelo a los datos (<em>χ²/gl </em>= 1.75; CFI = 0.92; IFI = 0.92; TLI = 0.90; RMSEA = .05 y SRMR =.05), brindando evidencias de validez de la estructura de seis factores. Según lo anterior se considera que la escala para medir satisfacción y frustración de las tres necesidades psicológicas básicas puede ser utilizada preliminarmente en estudiantes universitarios en el contexto de la educación superior chilena, permitiendo también la relación con otras variables de interés para generar modelos explicativos que permitan profundizar la comprensión de aspectos que son de interés institucional.</p>

The research aims to obtain the most appropriate combination treatment of Azolla inoculum dose and catfish seed size in dual system Azolla - catfish, which is able to provide the highest catfish yield. The experiments were performed in catfish ponds in completely randomized design (CRD) two factors, i,e azolla inoculum doses (250, 500 and 750 gm<sup>-1</sup>) and head circumference size of catfish seed (3, 4 and 5 cm). Dose of catfish seed is 2,000 head / m<sup>2</sup>. Variables observed were azolla fresh weight and catfish fresh weight at harvest. Azolla inoculum and catfish seed deployed together in catfish ponds and feeding with concentrate feed for one month. Azolla and catfish harvesting is done on the same day using a sieve. Once drained, Azolla and catfish were weighed separately to determine the severity. Data were analyzed by F test at the level of 95%, followed by Duncan's multiple range test (DMRT) if any significance influence. The results showed that the higher the azolla inoculum number, the higher azolla yield. The larger the size of catfish seed the higher catfish consumption to Azolla. Catfish seed size more than 4 cm will cause an imbalance between the speed of consumption of Azolla by the catfish and the azolla growth rate, so that Azolla be devoured by catfish.</em></p></div>

Published: March 2018

The process of recognising printed mathematical expression consists of two general processes: symbol recognition and structural analysis which reads the expression structure and the relation between symbols within the structure, provide adequate labeling to preserve it, and finally be useful to reconstruct the whole expression.This research focused on comparing the effectivity of two correlation-based pattern matching algorithms: the well-established Sum of Squared Difference (SSD) and the relatively new Optimized Sum of Absolute Difference (OSAD) which is based on average face rather than mathing all trained symbols. Which one was better will be used on the next stage of a research on converting printed mathematical expression into LaTeX notation.. Results obtained from tests conducted shown that (1) the accuracy of OSAD is 85.6% and SSD is 70,6% on various test symbols, and (2) the usage of average face in OSAD which was proposed to reduce time needed for matching, proven to have no negative effects on its matching performance. Therefore OSAD is well ahead in processing time and accuracy than SSD.

Acceptability and Feasibility of a Trial Testing Allocation to Sunscreen and a Smartphone App for Sun Protection: Discontinued Randomized Controlled Trial (Preprint)
Authors: Rodrigues Angela M , Sniehotta Falko F , Birch-Machin Mark A , Olivier Patrick , Ara�jo-Soares Vera 
Published: March 2018

BACKGROUND

Recreational sun exposure has been associated with melanoma prevalence, and tourism settings are of particular interest for skin cancer prevention. Effective, affordable, and geographically flexible interventions to promote sun protection are needed.

OBJECTIVE

The aim of this study was to describe the protocol for a definitive randomized controlled trial (RCT) evaluating a smartphone mobile intervention (mISkin app) promoting sun protection in holidaymakers and to assess the acceptability and feasibility of the mISkin app and associated trial procedures in an internal pilot study.

METHODS

Participants were recruited from the general community. Holidaymakers traveling abroad and owning a smartphone were enrolled in the internal pilot of a 2 (mISkin vs control) x 2 (sun protection factor [SPF] 15 vs SPF 30) RCT with a postholiday follow-up. The smartphone app is fully automated and entails a behavioral intervention to promote sun protection. It consisted of five components: skin assessment, educational videos, ultraviolet (UV) photos, gamification, and prompts for sun protection. Participants were also randomly allocated to receive sunscreen SPF 15 or SPF 30. Primary outcomes for the internal pilot study were acceptability and feasibility of trial procedures and intervention features. Secondary outcomes were collected at baseline and after holidays through face-to-face-assessments and included skin sun damage, sunscreen use (residual weight and application events), and sun protection practices (Web-based questionnaire).

RESULTS

From 142 registers of interest, 42 participants were randomized (76% [32/42] female; mean age 35.5 years). Outcome assessments were completed by all participants. Random allocation to SPF 15 versus SPF 30 was found not to be feasible in a definitive trial protocol. Of the 21 people allocated to the mISkin intervention, 19 (91%) installed the mISkin on their phones, and 18 (86%) used it at least once. Participants were satisfied with the mISkin app and made suggestions for further improvements. Due to difficulties with the random allocation to SPF and slow uptake, the trial was discontinued.

CONCLUSIONS

The internal pilot study concluded that randomization to SPF was not feasible and that recruitment rate was slower than expected because of difficulties with gatekeeper engagement. Possible solutions to the problems identified are discussed. Further refinements to the mISkin app are needed before a definitive trial.

Figuras que irrompem no desacordo: proposições através d’A Mosca e Holy Motors
Authors: Rezende Isabel Veiga 
Published: March 2018

O presente trabalho propõe uma análise detalhada de duas sequências dos filmes A Mosca(David Cronenberg, 1986) e Holy Motors (Leos Carax, 2016). Buscamos mostrar como ambas as passagens concentram e explicitam o desacordo entre corpo e pessoa/sujeito, inventando uma nova lógica figurativa para os protagonistas. No primeiro caso, um cientista que se transforma em inseto gigante, e no segundo um ator que se confunde com seus personagens. Nos alimentamos de uma questão cara ao cinema moderno, a saber, a insubordinação a tudo que limita o Homem a um ser biológico, comunicativo e racional. Afastando-se dos modelos naturalistas, o cinema (e as outras artes) pode então contrariar sua suposta vocação realista e experimentar o enlouquecimento das formas fílmicas, em que as forças de deformação e metamorfose agem substancialmente sobre as forças de conservação e contenção.
