Análisis cualitativo y cuantitativo de la oferta de piscinas cubiertas en las Comunidades Autónomas españolas
La natación recreativa es la actividad físico-deportiva con mayor volumen de practicantes en España. Esta actividad se ha visto favorecida en los últimos años por el progresivo incremento de la oferta de piscinas cubiertas, siendo este espacio el que presenta mayor intensidad de uso. Distintos estudios han destacado la asociación positiva entre la disponibilidad de instalaciones deportivas y los niveles de actividad física de la población. El análisis cuantitativo y cualitativo de la oferta de piscinas cubiertas en las Comunidades Autónomas puede resultar un excelente indicador del grado de desarrollo de estas instalaciones en la consecución de un entorno social más saludable. Para ello, se seleccionaron 12 variables por un grupo de expertos que permitieran el análisis de la oferta de piscinas cubiertas en las regiones, y mediante el análisis con un Indicador Sintético de Piscinas Cubiertas (ISPC) se clasificó a las Comunidades Autónomas en 4 niveles de desarrollo (Bajo, Medio-Bajo, Medio Alto y Alto). Los resultados ofrecen una gran disparidad entre las regiones en sus dotaciones de piscinas cubiertas, fruto de las diferentes inversiones políticas, culturas deportivas y realidades sociales, situándose en los primeros puestos las Comunidades Autónomas con mayor práctica deportiva. Este estudio puede servir de herramienta para una mejor planificación deportiva de las Autonomías y entidades promotoras del deporte. Palabras clave: piscinas cubiertas, indicador sintético, planificación deportiva, posicionamiento, comunidades autónomas.
The physical-sport activity more practiced in Spain is the recreational swimming. In recent years, this activity has been amplified by the progressive increment of indoor pools, being these types of spaces, the ones that present more use. Different studies have manifested the positive association between the availability of sports facilities and levels of population’s physical activity. The qualitative and quantitative analysis of the offer of indoor swimming pools in Autonomous Communities can result an excellent indicator of the degree of development of these facilities, to achieve a healthy social context. For this study, 12 variables by a group of experts were selected to permit the analysis of the offer of indoor swimming pools in the Autonomous Communities. With the analysis of a Synthetic Indicator of Indoor Pools (ISPC), was classified each Autonomous Community into 4 levels of development (Low, Lower-Middle, Upper-Medium and Upper). The results demonstrate the great disparities between Autonomous Communities with regards of their resources in indoor swimming pools, which has been produced from different political investments, sports cultures and social realities, being in the first positions the Autonomous Communities with higher levels sports practice. This study can be a useful tool for better sports planning’s in Autonomies and also for companies of the sport. Key words: indoor pools, synthetic indicator, sports planning, ranking, autonomous communities
Los hayedos prepirenaicos aragoneses:: fitosociología, fitotopografía y conservación
Tras el estudio de los hayedos prepirenaicos aragoneses (provincias de Zaragoza y Huesca), los autores presentan una tabla de más de 50 inventarios correspondiente al Buxo- Fagetum sylvaticae y explican su composición florística, hábitat y fitotopografía. También se dan tres inventarios del Scillo-Fagetum sylvaticae, mucho más localizado en esta región. Por último, se describe su estado de conservación y se dan algunas recomendaciones para su protección.Prepyrenean aragonese beech-forests (Zaragoza and Huesca provinces) were studied during two years. As a result we present a table of the Buxo-Fagetum sylvaticae (56 releves), a widespread community, and comment on its floristical composition and ecology.Also the more isolated beech-forest of the Scillo-Fagetum sylvaticae is here introduced (3 releves). Finally, some ideas for conservation of these forests are also pointed out
Knowledge Graph Question Answering for Materials Science (KGQA4MAT): Developing Natural Language Interface for Metal-Organic Frameworks Knowledge Graph (MOF-KG)
We present a comprehensive benchmark dataset for Knowledge Graph Question
Answering in Materials Science (KGQA4MAT), with a focus on metal-organic
frameworks (MOFs). A knowledge graph for metal-organic frameworks (MOF-KG) has
been constructed by integrating structured databases and knowledge extracted
from the literature. To enhance MOF-KG accessibility for domain experts, we aim
to develop a natural language interface for querying the knowledge graph. We
have developed a benchmark comprised of 161 complex questions involving
comparison, aggregation, and complicated graph structures. Each question is
rephrased in three additional variations, resulting in 644 questions and 161 KG
queries. To evaluate the benchmark, we have developed a systematic approach for
utilizing ChatGPT to translate natural language questions into formal KG
queries. We also apply the approach to the well-known QALD-9 dataset,
demonstrating ChatGPT's potential in addressing KGQA issues for different
platforms and query languages. The benchmark and the proposed approach aim to
stimulate further research and development of user-friendly and efficient
interfaces for querying domain-specific materials science knowledge graphs,
thereby accelerating the discovery of novel materials.Comment: In 17th International Conference on Metadata and Semantics Research,

Metadata for Scientific Experiment Reporting: A Case Study in Metal-Organic Frameworks
Research methods and procedures are core aspects of the research process.
Metadata focused on these components is critical to supporting the FAIR
principles, particularly reproducibility. The research reported on in this
paper presents a methodological framework for metadata documentation supporting
the reproducibility of research producing Metal Organic Frameworks (MOFs). The
MOF case study involved natural language processing to extract key synthesis
experiment information from a corpus of research literature. Following, a
classification activity was performed by domain experts to identify
entity-relation pairs. Results include: 1) a research framework for metadata
design, 2) a metadata schema that includes nine entities and two relationships
for reporting MOF synthesis experiments, and 3) a growing database of MOF
synthesis reports structured by our metadata scheme. The metadata schema is
intended to support discovery and reproducibility of metal-organic framework
research and the FAIR principles. The paper provides background information,
identifies the research goals and objectives, research design, results, a
discussion, and the conclusion.Comment: Accepted by the 17th International Conference on Metadata and

Covalently linked organic networks
In this review, we intend to give an overview of the synthesis of well-defined covalently bound organic network materials such as covalent organic frameworks, conjugated microporous frameworks, and other "ideal polymer networks" and discuss the different approaches in their synthesis and their potential applications. In addition we will describe the common computational approaches and highlight recent achievements in the computational study of their structure and properties. For further information, the interested reader is referred to several excellent and more detailed reviews dealing with the synthesis (Dawson et al., 2012; Ding andWang, 2013; Feng et al., 2012) and computational aspects (Han et al., 2009; Colón and Snurr, 2014) of the materials presented here
Building Open Knowledge Graph for Metal-Organic Frameworks (MOF-KG): Challenges and Case Studies
Metal-Organic Frameworks (MOFs) are a class of modular, porous crystalline
materials that have great potential to revolutionize applications such as gas
storage, molecular separations, chemical sensing, catalysis, and drug delivery.
The Cambridge Structural Database (CSD) reports 10,636 synthesized MOF crystals
which in addition contains ca. 114,373 MOF-like structures. The sheer number of
synthesized (plus potentially synthesizable) MOF structures requires
researchers pursue computational techniques to screen and isolate MOF
candidates. In this demo paper, we describe our effort on leveraging knowledge
graph methods to facilitate MOF prediction, discovery, and synthesis. We
present challenges and case studies about (1) construction of a MOF knowledge
graph (MOF-KG) from structured and unstructured sources and (2) leveraging the
MOF-KG for discovery of new or missing knowledge.Comment: Accepted by the International Workshop on Knowledge Graphs and Open
