Sensitive period is the right time to instill the basis of the importance of counting. In addition to counting skills that must be developed also pay attention to the application of learning used. However, in the learning process, teachers often forget the importance of playing methods. If too often with giving assignments the child will feel bored, therefore what is used is the method of playing. Play method is one method that can be used by teachers to teach the ability to count children in the beginning. Based on this background, the purpose of this study was to determine the effect of the use of playing methods on initial numeracy skills. This study used the Quasi Experiment method with the Nonequevalent Control Group Design research design. The results of the pre test showed that there were no significant differences in the experimental group and the control group with p-value> 0.05, which was 0.135> 0.05 which was tested by the two average test results. While the post-test results showed that the initial numeracy ability after the application of the playing method experienced a significant difference with the p-value <0.05, that is with the results of 0.0001 with the Mann-Whitney test. This method of playing can be used as a learning suggestion for educators to improve their ability to have an early start.

Problemática epistemológica y sociológica de la teoría administrativa
Authors: Ballina Ríos Francisco
Published: November 2019

Este artículo plantea un debate y una discusión teórica a la problemática epistemológica y sociológica de la teoría administrativa de Latinoamérica. En la primera existe una polisemia de teorías, conceptos y significados. Y en la segunda, constatamos que estas teorías provienen de contextos sociales, económicos y culturales diferentes al nuestro. El alcance del estudio radica en su aportación crítica al debate teórico; su limitante es realizar investigación empírica en cada país. La discusión se focaliza en la crítica de la teoría convencional de la administración que desde perspectivas funcionalistas y positivistas distraen las cuestiones básicas de la sociedad como el poder, la dominación, la explotación. En contraposición a estos enfoques, se describen sintéticamente algunas agendas no convencionales de investigación en administración.

Adoption of diagnostic digital pathology in Finland
Authors: Näpänkangas Juha , Tolonen Teemu
Published: November 2019

Digital pathology (DP) means digitizing histological glass slides for the assessment on a computer screen. In clinical diagnostics, DP is expected to reduce costs due to improved pathologist productivity with the aid of image analysis, workload distribution, and more accurate subspecialty-based diagnoses. The digital workflow also provides many advantages to research and education. However, the adoption of DP into clinical diagnostics has been slow. In this study, the current state and attitudes of the adoption of DP were explored with a questionnaire sent to the persons in charge of digitalization in all public pathology laboratories in Finland.

Most of the respondents (75.0%) considered that there is a sufficient amount of validation studies about the safety of DP. The benefits of DP were seen in e.g. tumor boards (64.3%), logistics (64.3%), diagnostic quality (50.0%), and consultations (64.3%). All but one (92.9%) expected the level of digitalization to reach 100% in the following 12 years. The price of digitalization, specifically the cost of storage, was considered to be the most important barrier to a large-scale adoption of DP.

The results suggest that there is a need for a substantial governmental financing: the virtual slide images could be stored in a central national image archive (e.g. Kvarkki) after diagnostics, leading to a remarkably reduced cost of local storage and an accelerated large-scale adoption of DP in the Finnish pathology laboratories. This would lead to improved diagnostic efficacy and quality by enabling better workload management locally and nationally. A central DP repository could serve as an invaluable database for e.g. biobank research
Empowering citizens through data interoperability - data federation applied to consumer-centric healthcare
Authors: Nokkala Tiina Anneli , Dahlberg Tomi
Published: November 2019

During the era of open systems, healthcare services and related data are in a constant flux caused by digital transformation. The amount, sources and dimensionality of data grow rapidly, and solutions for data governance, integration and interoperability are urgently needed. At the same time, digital data and information technology–enabled healthcare services are offered as a means to empower citizens. The objective is for active citizens to take better care of their own health. It is possible to support empowerment in many ways, such as with easy-to-use information systems (IS) or personal health records (PHR), or by supporting citizens’ participation in health data creation. In this article, we first present the federative approach to data governance with data federation matrixes in order to show how data are made interoperable by combining data from different data storages. Federation matrixes define shared attributes with their technical, information-flow and socio-contextual metadata. We then contemplate how the federative approach can be deployed to citizens’ healthcare data empowerment. We propose that data ontologies, e.g., data federation matrixes, are useful in bridging gaps between the social contexts of citizens and healthcare professionals and, by doing so, to promote citizen empowerment. The present article contributes to research on the federative approach to data governance, its deployment to citizens’ healthcare empowerment, and to the practice-oriented further development of the federation matrix tools for this and other use cases.

MEDigi is a nationwide Finnish project that aims to develop and implement digital teaching, learning and assessment solutions and to provide possibilities for national harmonization of undergraduate medical and dental education in Finland. The MEDigi project will investigate the options and feasibility of a common national digital online platform and produce digital content and solutions for medical education. Furthermore, tools and support system for digital pedagogy training will be created to ensure that the teaching staff will achieve and retain appropriate digipedagogical skills. The project aims also to increase the competence related to the digital tools used in clinical practice (eHealth, digital health) of physicians and dentists. Furthermore, academic research will be carried out on various aspects of the project. All the universities in Finland that offer the Licentiate Degree in Medicine and Dentist programmes are involved: Universities of Eastern Finland, Helsinki, Oulu, Tampere and Turku. The project is coordinated by the University of Oulu. The project is carried out in close collaboration with the Finnish Medical Society Duodecim and the Finnish Dental Society Apollonia. The project lifespan is until the end of May 2021. MEDigi project is financed by the Finnish Ministry of Culture and Education and its total budget is over 4 million euros.

Escherichia coli is a gram negative bacterium which is a normal flora in the digestive tract. In birds, this bacterium causes a disease known as colibasillosis. Antibiotics are generally used, but excessive use will cause residues and antibiotic resistance. To avoid resistance or residue, an alternative treatment is needed. The combination of propolis and ginger extract is very promising to develop because both have a synergistic effect as antimicrobials. The research aims to determine the effect of the combination extract on Escherichia coli bacteria in vitro. We used 8 groups which contain combinations of propolis and ginger extract. We used amoxicillin disk as a positive control, 1% Na CMC as a negative control. The results showed a combination of ginger and propolis extract showed good inhibitory activity against Escherichia coli in all groups> 6mm., and the highest inhibitory activity was K3 (5% propolis combination and 15% ginger extract) with 8.7 mm. The combination of propolis and ginger extract has the potential to be used as an alternative antibiotic to prevent antibiotic resistance from synthetic antibiotics.Keywords: alternative antibiotics, combination extracts, Escherichia coli, ginger, in vitro, propolis
Por la ventana del tiempo

El siguiente artículo indaga en un fenómeno particular del arte moderno y contemporáneo argentino: la apropiación, por parte de ciertos artistas, de obras pictóricas nacionales del pasado para producir las propias. Si bien se reconoce a la cita como un elemento constitutivo de la historia del arte, para este análisis partiremos de la hipótesis de que la apropiación de obras nacionales es particularmente frecuente en momentos de inestabilidad política y social, y que los artistas parten de ellas para abrir nuevos puntos de vista respecto al pasado. Se analizarán puntualmente algunos casos de apropiación iconográfica de la obra Sin pan y sin trabajo (1894), de Ernesto de la Cárcova, realizados durante el siglo XX. Finalmente, se hará una primera aproximación al apropiacionismo como operatoria del arte contemporáneo, donde esta misma obra resulta reinterpretada con frecuencia.
Genealogías del disenso luminoso

Se propone el trazado de una genealogía para la fotografía contemporánea y colectiva. Se establecen tres coordenadas que dibujan un itinerario significativo en la transformación de los regímenes escópicos argentinos: fotografías del siglo XIX producidas en función de géneros hegemónicos vinculados a la estabilización de la foto como medio de representación de la cultura dominante y de la construcción de una identidad nacional mirando hacia afuera; la emergencia, en las primeras décadas del siglo XX, de prácticas fotográficas disensuales respecto de ese enclave; y el desarrollo contemporáneo de la fotografía colectiva como (re)aparición y fortalecimiento de algunos de los elementos que pueden considerarse como la evidencia histórica de una forma de producir fotografía desde la resistencia (inter)subjetiva, el disenso político y el despliegue de identidades anti statu quo.

In cotton, factors such as carbon sources, hormonal combination, and type of explant influence the responses to callus induction. In this study callus induction was optimized to get high-frequency callus in cotton. Different carbon sources were tested, and among them, glucose at 3% was found to be the best carbohydrate in callus induction. Culture medium supplemented with 2,4-D (0.1 mg.L-1) and KIN (0.5 mg.L-1) gave a high callogenesis response, unlike other hormonal combinations. With explants, hypocotyl (72.93%) appeared easier to induce callus than cotyledon (48.75%) following root (37.5%). So, carbone sources, hormone, and their concentration affect significantly callus induction. The highest frequency of callus induction was then observed when hypocotyl explants were cultured on medium supplemented with 0.1 mg.L-1 of 2,4-D in combination with 0.5 mg.L-1 of KIN and 3% glucose. The induced-callus obtained were friable and of high quality. The other types of combinations resulted in the formation of compact callus with sometimes roots emerging from it. The present study may provide an efficient protocol to improve the callogenesis responses by adjusting the carbohydrates, the hormonal regime, and the type of explant to be cultured for a high-frequency callus induction of the Y331B-R5 cotton cultivar.
