Análisis de la incidencia de la ACDI y de la red ECPAT internacional sobre la erradicación de la explotación sexual infantil en niños, niñas y adolescentes en el contexto del turismo, proyecto “La Muralla soy yo” (2009-2011), Cartagena de indias

La Explotación Comercial sexual de los niños, niñas y adolescentes – ESCNNA ha ocasionado graves repercusiones en la sociedad, sometiendo a los menores a situaciones que atentan contra su integridad física y psicológica. Por ello, en el marco internacional y nacional se han adelantado diferentes iniciativas para erradicar dicho fenómeno. La Cooperación Internacional para el desarrollo- CI ha sido una valiosa herramienta en el tratamiento del flagelo dados los diferentes canales de ayuda los cuales han contribuido para su intervención. En este sentido, la CI por medio de la Agencia Canadiense para el desarrollo internacional- ACDI y la Fundación Renacer- ECPAT Internacional (End Child Prostitution, Pornography & Trafficking of Children for Sexual Purposes) hicieron posible junto con otros actores el proyecto de CI en Cartagena llamado: “La Muralla soy yo”, el cual buscó la prevención y futura erradicación de la Explotación Sexual de niños y adolescentes en el turismo- ESNAT en la ciudad. En el presente estudio de caso se pretende identificar cómo la CI incide por medio de la ACDI y la red ECPAT Internacional en instituciones locales de Cartagena para la prevención y posible erradicación del problema de la Explotación comercial sexual infantil en niños, niñas y adolescentes, en el contexto del turismo.

Navigation assistance for wayfinding in the virtual environments: taxonomy and a survey

Efficient Navigation is essential for the user-acceptance of the Virtual Environments (VEs), but it is also inherently, a difficult task to perform. Resulting research in the area provides users with great variety of navigation assistance in VEs however it is still known to be inadequate, complex and suffers through many limitations. In this paper we discuss the task of navigation in the virtual environments and record the wayfinding assistance currently available for the VEs. The paper introduces taxonomy of navigation and categorizes the aids on basis of the functions performed. The paper provides views on current work performed in the area of non-speech auditory aids. Further we conclude by providing views on the important areas that require further investigation and research.

WCCC 2013: the 20th World Computer Chess Championship

The 20th World Computer Chess Championship took place in Yokohama, Japan during August 2013. It was narrowly won by JUNIOR from JONNY with HIARCS, PANDIX, SHREDDER and MERLIN occupying the remaining positions. There are references to the detailed chess biographies of the engines and engine-authors in the Chessprogramming Wiki. The games, occasionally annotated, are available here.

WCSC 2013: the 3rd World Chess Software Championship

The 3rd World Chess Software Championship took place in Yokohama, Japan during August 2013. It pits chess engines against each other on a common hardware platform - in this instance, the Intel i7 2740 Ivy Bridge with 16GB RAM supporting a potential eight processing threads. It was narrowly won by HIARCS from JUNIOR and PANDIX with JONNY, SHREDDER and MERLIN taking the remaining places. Games, occasionally annotated, are available here.

Computer-aided operation planning and 3-dimensional osteotomy guidance for alveolar distraction

Objectives: In alveolar distraction, in cases of severe atrophy in particular, it is often difficult to perform osteotomies in order to make a transport segment in optimal size and shape. Moreover care must be taken, not to damage the closely locating anato- mical structures such as the maxillary sinus, the inferior alveolar nerve, and the roots of the neighboring teeth. For setting ideal osteotomy lines exactly, we have developed a CT-based preoperative planning tool. Methods: 3-dimensional visual reconstruction of the jaw is created from the preoperative CT scans (1.0-mm slice thick- ness). Using the image-processing software Mimics (Materialise, Yokohama, Japan), various procedures of virtual cutting are simulated first to determine optimal osteotomy lines and to design an ideal transport segment. After the computer planning, data from the virtual solid model are transferred to a rapid prototype model, and a guiding splint is made to transfer the planned surgical simulation to the actual surgery. Results: The method was used in a case of severe atrophy of the anterior maxilla. The patient had a large maxillary sinus requir- ing a precise osteotomy in this critical area. Using the splint allowing a 3-dimensional guidance, alveolar osteotomies were easily done to achieve a transport segment in sufficient dimen- sion as planned, and any perforation of the maxillary sinus could be avoided. Finally the alveolar distraction of 10mm has suc- cessfully been performed. Conclusion: The preoperative planning method and the guiding splint described here are useful in problematic cases requiring an extremely precise osteotomy due to lack of bony space.
