description: The SIMPLE Archive project -- the Substellar and IMaged PLanet Explorer Archive of Complex Objects -- is an endeavor to create a collaboratively maintained database of low-mass stars, brown dwarfs, and directly-imaged planetary mass objects using GitHub, Python, and SQL. We envision the SIMPLE Archive to eventually hold lightly curated data for free-floating brown dwarfs/planetary-mass objects and late-type/substellar companions to stars. We plan to archive data for brown dwarfs with spectral types M7 and later and directly imaged planetary mass objects, including their spectra, images, and modeled parameters. A major goal of this project is to facilitate the sharing of JWST spectra among interested community members. We are in the process of making both a website and a command line interface to interact with the archive, including both data queries and ingestion. The website will provide a way to visualize spectra and images of objects in the archive. We are actively building and populating the database and developing the website via weekly co-working meetings. The current development team includes folks from a range of career stages, programming experience levels, and astronomy experience and we welcome more people to join us! All of the code and objectives can be found on GitHub at https://github.com/SIMPLE-AstroDB/SIMPLE-db/ and https://github.com/SIMPLE-AstroDB/SIMPLE-web/. Folks can also join the Simple Archive Google group for occasional project updates and/or the #simple-db-dev channel in the Astropy Slack workspace for development discussion.

description: A central issue in the comparative study of any linguistic category and its patterns is the necessity of choosing specific exponents in the target languages. This is particularly relevant for lexical domains rendering subjective and highly culturally informed phenomena such as emotions. We propose an alternative to the common solution of translating from English via native speaker inquiry and/or dictionaries. Elaborating upon current methodology in typological studies, we devised a systematic elicitation task which incorporates insights from cross-cultural psychological and anthropological research on human emotions. Our method facilitates the elicitation of extensive comparable inventories of emotion lexemes, many of which lack straightforward English equivalents and thus could not have been captured by a traditional translation-based approach. We show that this method can be used to investigate specific structural phenomena such as the psych alternation from a cross-linguistic perspective while minimizing translational bias.
Immigrant women and wife abuse : a phenomenological exploration
Creators: name: Wiik, Maija-Liisa
Publisher: name: University of British Columbia
Year: 2009

description: A qualitative phenomenological research design was used to explore and illustrate the experience of living in and leaving an abusive relationship for immigrant women. Five women from various cultural backgrounds from the Greater Vancouver area volunteered to describe their experiences of living in and leaving their abusive marriages in individual, in-depth, audiotaped interviews. Eight common themes were extracted from the interview transcripts using Colaizzi's (1978) seven-step procedure for phenomenological data analysis. The results indicated that the women felt increasingly vulnerable and at risk, accountable for the abuse, ashamed and worthless, and betrayed and abandoned the longer they stayed in their relationships. While the women continued to act in many resourceful ways to control the abuse and to maintain their personal freedom, they experienced that their sense of self was eroding and that they became increasingly trapped in their marriages. While most of the participants did not mention lack of language proficiency as a barrier, they all felt that their unfamiliarity with the larger Canadian society contributed to a sense of isolation and unawareness of their rights and available services. The participants reported that these factors compounded their fear and entrapment in their abusive relationships. The women reported that concern for their and their children's safety and welfare, and the meaninglessness of their lives if they stayed in their abusive relationships, served as catalysts for them to move out. While the participants in this study continued to struggle with such things as finances, helping their children to heal from the adverse affects of the abuse, and their own healing after they had left their abusive husbands, they all reported enjoying their new found freedom and independence, and their stronger sense of self and self-reliance that had emerged during the process.

description: At the beginning of this study we set out to define what is language, multilingualism and multi-culturalism today, but also the laws that govern their development. At the same time, we attempted a historical overview, by presenting the portraits of six well-known multilinguals of the past, their work and their ideas within the era they lived. We also included the interviews of twelve multilingual individuals of our time. They offer their own point of view on the subject in question. Next, we analysed their answers and presented our findings in statistically-oriented charts. At the last section, we attempted a comparative study of multilingualism both in a historical manner and in synchrony.

En même temps, nous avons fait une enquête historique montrant six célèbres multilingues, leur œuvre, leurs idées et leur influence à l'époque dans laquelle ils vivaient et agissaient. On a cité également des interviews de douze personnes multilingues actuelles qui donnent leur point de vue sur la question du multilinguisme et de la façon dont il a contribué à leur développement personnel. Nous avons analysé leurs réponses et représenté graphiquement les statistiques qui en découlent. Enfin, nous avons tenté une étude comparative du multilinguisme comme démontré dans la recherche historique et comme en témoignent les entretiens de multilingues contemporaines.

description: We present a simple model-free control algorithm that is able to robustly learn and stabilize an unknown discrete-time linear system with full control and state feedback subject to arbitrary bounded disturbance and noise sequences. The controller does not require any prior knowledge of the system dynamics, disturbances, or noise, yet it can guarantee robust stability and provides asymptotic and worst-case bounds on the state and input trajectories. To the best of our knowledge, this is the first model-free algorithm that comes with such robust stability guarantees without the need to make any prior assumptions about the system. We would like to highlight the new convex geometry-based approach taken towards robust stability analysis which served as a key enabler in our results. We will conclude with simulation results that show that despite the generality and simplicity, the controller demonstrates good closed-loop performance.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The application of Bayesian methods in cosmology and astrophysics has flourished over the past decade, spurred by data sets of increasing size and complexity. In many respects, Bayesian methods have proven to be vastly superior to more traditional statistical tools, offering the advantage of higher efficiency and of a consistent conceptual basis for dealing with the problem of induction in the presence of uncertainty. This trend is likely to continue in the future, when the way we collect, manipulate and analyse observations and compare them with theoretical models will assume an even more central role in cosmology. This review is an introduction to Bayesian methods in cosmology and astrophysics and recent results in the field. I first present Bayesian probability theory and its conceptual underpinnings, Bayes' Theorem and the role of priors. I discuss the problem of parameter inference and its general solution, along with numerical techniques such as Monte Carlo Markov Chain methods. I then review the theory and application of Bayesian model comparison, discussing the notions of Bayesian evidence and effective model complexity, and how to compute and interpret those quantities. Recent developments in cosmological parameter extraction and Bayesian cosmological model building are summarized, highlighting the challenges that lie ahead.

To achieve this goal, prior to final analysis, the concept of stock market and economic cycles, the meaning and the historical development of the stock market and the Greek economy. In addition, we study the connection of two key concepts, the stock market and the economy. Necessary for the preparation of this work is the study of basic variables of the economy and the general index of the stock exchange, which contribute to useful conclusions about the extent to which the Greek stock market follows the theory of economic cycles. The study revealed that the Greek economy and the general price index following cycles.
Distributivity and Additivity: The Case of the Romanian Distributive Marker "câte"

description: The paper explores the semantic import of Romanian nominal distributive marker “câte” and identifies two distinct contributions to the interpretation of the DP hosting it: a licensing condition excluding non-distributive interpretations and an additivity implicature requiring that the distributive share should be monotonic with respect to the sortal key. The latter property can only be tested when the marker modifies measure phrases. For this purpose, an experiment was conducted in order to test the hypothesis that the association between “câte” and non-monotonic measure phrases correlates with a significantly lower acceptability as opposed to “câte” and monotonic measure phrases.
Enhanced Balancing GAN: Minority-class Image Generation

description: Generative adversarial networks (GANs) are one of the most powerful generative models, but always require a large and balanced dataset to train. Traditional GANs are not applicable to generate minority-class images in a highly imbalanced dataset. Balancing GAN (BAGAN) is proposed to mitigate this problem, but it is unstable when images in different classes look similar, e.g. flowers and cells. In this work, we propose a supervised autoencoder with an intermediate embedding model to disperse the labeled latent vectors. With the improved autoencoder initialization, we also build an architecture of BAGAN with gradient penalty (BAGAN-GP). Our proposed model overcomes the unstable issue in original BAGAN and converges faster to high quality generations. Our model achieves high performance on the imbalanced scale-down version of MNIST Fashion, CIFAR-10, and one small-scale medical image dataset.

description: This is the first book on the subject of room-temperature superconductivity. The main purpose of the book is twofold. First, to show that, under suitable conditions, superconductivity can occur above room temperature. Secondly, to present general guidelines on how to synthesize a room temperature superconductor. The book begins with an introduction into the physics of the superconducting state and superconducting materials. The mechanisms of conventional, half-conventional and unconventional superconductivity are discussed in the following chapters. The last three chapters of the book are devoted to room temperature superconductivity. In Chapter 2, an attempt to review the basic properties of the superconducting state independently of any specific mechanism is made for the first time. In addition, four principles of superconductivity valid for any type of superconductivity are introduced in Chapter 4. The book is mainly addressed to specialists in materials science and in the field of superconductivity. At the same time, students will also benefit from reading the first nine chapters of the book.

description: Pronominal reference to the non-head element of a compound (e.g., „truck“ in “truck driver”) has previously been reported to be ungrammatical. In this paper, we hypothesize that the grammatical status of proper names may make them more acceptable as a non-head referent to a pronoun. However, our experimental results fail to provide support for any ban on pronoun reference to non-heads, regardless of whether they are proper names or common nouns.

Όπως προέκυψε μέσα από τη θεωρητική διερεύνηση όσο και από τα ερευνητικά δεδομένα, η αξιολόγηση της μαθηματικής επάρκειας μπορεί να χρησιμοποιηθεί προβλεπτικά για την αξιολόγηση της επίδοσης στα μαθηματικά. Συγκεκριμένα, τα ευρήματα έδειξαν ότι οι μαθητές/τριες που απέδωσαν καλά στο κριτήριο μαθηματικής επάρκειας, απέδωσαν εξίσου καλά και στο κριτήριο επίδοσης στα μαθηματικά, καθώς και το αντίστροφο.
description: The purpose of this research is the investigation of the relationship between mathematical competence and achievement in mathematics of fourth and fifth primary school graders, as those two were evaluated through the mathematical competence test and the test of achievement in mathematics. The conclusion of theoretical research, as well as the results of the tests, showed that the evaluation of mathematical competence can be used in order to predict achievement in mathematics. To be more specific, the findings revealed that students who did well in the mathematical competence test, did also well in the test of achievement in mathematics and the opposite.
'Almost' in Early and Late Modern English: Turning on the Parametric Screw (But Not Tightly Enough to Change a Parameter)

description: This contribution investigates the decompositional behavior of ‘almost’ in Early and Late Modern English (EModE/LModE), i.e.: whether the adverb is able to modify result states of predicates to which it attaches, in addition to the default possibility of modifying the meaning of the entire events. ‘Almost’ is found to be decompositional in EModE at a time when ‘again’ was not truly so (Beck & Gergel, 2015; Gergel & Beck, 2015). This supports the view that decompositionality is primarily a lexical property. The trajectory of the decompositional behavior in EModE and LModE is, however, complicated by a series of factors, and some possible tendencies towards its decline are observed.
Superparamagnetic dynamics and blocking transition in Fe$_3$O$_4$ nanoparticles probed by vibrating sample magnetometry and muon spin relaxation

description: The magnetic properties of Fe$_3$O$_4$ nanoparticle assemblies have been investigated in detail through a combination of vibrating sample magnetometry and muon spin relaxation ($μ$SR) techniques. Two samples with average particle sizes of 5 nm and 20 nm, respectively, were studied. For both samples, the magnetometry and $μ$SR results exhibit clear signatures of the superparmagnetic state at high temperature and the magnetically blocked state at low temperature. The $μ$SR data demonstrate that the transition from the superparamagnetic to the blocked state occurs gradually throughout the sample volume over a broad temperature range due to the finite particle size distribution of each sample. The transition occurs between approximately 3 K and 45 K for the 5 nm sample and 150 K and 300 K for the 20 nm sample. The magnetometry and $μ$SR data are further analyzed to yield estimates of microscopic magnetic parameters including the nanoparticle spin-flip activation energy $E_A$, magnetic anisotropy $K$, and intrinsic nanoparticle spin reversal attempt time $τ_0$. These results highlight the complementary information about magnetic nanoparticles that can be obtained by bulk magnetic probes such as magnetometry and local magnetic probes such as $μ$SR.

description: Global stability of the spherically symmetric nonisentropic compressible Euler equations with positive density around global-in-time background affine solutions is shown in the presence of free vacuum boundaries. Vacuum is achieved despite a non-vanishing density by considering a negatively unbounded entropy and we use a novel weighted energy method whereby the exponential of the entropy will act as a changing weight to handle the degeneracy of the vacuum boundary. Spherical symmetry introduces a coordinate singularity near the origin for which we adapt a method developed for the Euler-Poisson system by Guo, Hadžić and Jang to our problem.

description: Σκοπός της παρούσας διπλωματικής εργασίας είναι η εξέταση των επιπτώσεων της οικονομικής κρίσης στο εκπαιδευτικό σύστημα της Ελλάδας. Σταδιακά γίνεται εμφανές ότι τα συμπτώματα της κρίσης επηρεάζουν την εκπαίδευση, όχι μόνο με οικονομικούς όρους, αλλά επίσης υπό μία περισσότερο ανθρωπιστική διάσταση. Η παρούσα έρευνα στοχεύει στη διερεύνηση των αντιλήψεων, των στάσεων και των προκαταλήψεων των εκπαιδευτικών απέναντι στο αντίκτυπο της κρίσης στο εκπαιδευτικό έργο και στην εκπαιδευτική διαδικασία. Σε ένα πρώτο στάδιο, εξετάζονται οι απόψεις των εκπαιδευτικών σχετικά με την υλική διάσταση της οικονομικής κρίσης στην εκπαίδευση. Σε ένα δεύτερο στάδιο, στο επίκεντρο τίθενται ζητήματα, όπως είναι η συσχέτιση της κρίσης με το ευρύτερο πολιτικό και κοινωνικό πλαίσιο της χώρας, καθώς και ο ρόλος των παιδαγωγών στην εξομάλυνση καταστάσεων που συνδέονται με την κρίση. Η έρευνά μας επιτρέπει στους εκπαιδευτικούς να παράγουν τη δική τους «φωνή» σχετικά με τους τρόπους με τους οποίους η κρίση ασκεί επίδραση στο ρόλο τους. Ως εκ τούτου, η συνέντευξη θεωρήθηκε ως το καταλληλότερο μεθοδολογικό εργαλείο. Τα δεδομένα αναλύονται μέσα από μια ποιοτική ανάλυση περιεχομένου, υπό το πρίσμα μιας κριτικο-ιδεολογικής οπτικής. Ο συνδυασμός της ποιοτικής ανάλυσης περιεχομένου με την κριτική ανάλυση δημιουργεί μια πιο εμπεριστατωμένη εικόνα για αυτά που κρύβονται πίσω από τα λεγόμενα των εκπαιδευτικών.
description: The purpose of the current master thesis is to examine the repercussions of the financial crisis in the educational system of Greece. Gradually, it becomes apparent that the symptoms of the crisis affect education not only in financial terms but also in a more humanistic dimension. This research aims to investigate the teachers’ perceptions, attitudes and prejudices towards the impact of the crisis on the educational work and the educational process. In a first step, we examined the teachers’ views regarding the materialistic dimension of the economic crisis in education. In a second stage, we focus on topics, such as the correlation of the crisis with the broader political and social context of the country, as well as the role of the educators in alleviating conditions associated with the crisis. Our research allows teachers to express their own "voice" about the ways in which the financial crisis has an impact on their own role. Therefore, the interview was considered to be the most appropriate methodological tool. The data are analyzed through a qualitative content analysis, in the light of a critical-ideological perspective. The combination of the qualitative content analysis with the critical analysis creates a more comprehensive depiction of what lies beneath the teachers’ words.

description: Evidence for triggered star formation is difficult to establish because energy feedback from massive stars tend to erase the interstellar conditions that led to the star formation. Young stellar objects (YSOs) mark sites of {\it current} star formation whose ambient conditions have not been significantly altered. Spitzer observations of the Large Magellanic Cloud (LMC) effectively reveal massive YSOs. The inventory of massive YSOs, in conjunction with surveys of interstellar medium, allows us to examine the conditions for star formation: spontaneous or triggered. We examine the relationship between star formation and gravitational instability on a global scale, and we present evidence of triggered star formation on local scales in the LMC.

description: In the globalized economic world, it has become important to understand the purpose behind infrastructural and construction initiatives occurring within developing regions of the earth. This is critical when the financing for such projects must be coming from external sources, as is occurring throughout major portions of the African continent. When it comes to imagery analysis to research these regions, ground and aerial coverage is either non-existent or not commonly acquired. However, imagery from a large number of commercial, private, and government satellites have produced enormous datasets with global coverage, compiling geospatial resources that can be mined and processed using machine learning algorithms and neural networks. The downside is that a majority of these geospatial data resources are in a state of technical stasis, as it is difficult to quickly parse and determine a plan for request and processing when acquiring satellite image data. A goal of this research is to allow automated monitoring for largescale infrastructure projects, such as railways, to determine reliable metrics that define and predict the direction construction initiatives could take, allowing for a directed monitoring via narrowed and targeted satellite imagery requests. By utilizing photogrammetric techniques on available satellite data to create 3D Meshes and Digital Surface Models (DSM) we hope to effectively predict transport routes. In understanding the potential directions that largescale transport infrastructure will take through predictive modeling, it becomes much easier to track, understand, and monitor progress, especially in areas with limited imagery coverage.

This spike in technological growth exponentially increased the need for a human performance metric in 3D space. Fitts' law is perhaps the most widely used human prediction model in HCI history attempting to capture human movement in lower dimensions. Despite the collective effort towards deriving an advanced extension of a 3D human performance model based on Fitts' law, a standardized metric is still missing. Moreover, most of the extensions to date assume or limit their findings to certain settings, effectively disregarding important variables that are fundamental to 3D object interaction. In this review, we investigate and analyze the most prominent extensions of Fitts' law and compare their characteristics pinpointing to potentially important aspects for deriving a higher-dimensional performance model. Lastly, we mention the complexities, frontiers as well as potential challenges that may lay ahead.

description: Grazing system management is for supplying inexpensive, adequate nutrition for the goat enterprise. This involves managing forages to facilitate dry matter production and managing grazing so forage quality is adequate and harvest efficiency is high while avoiding consuming internal parasites. Since nutrient costs are greatest for winter, the grazing system should be planned to provide some grazing during winter. The forage system should be managed to provide the greatest proportion of nutrients possible during kidding and lactation. The base forage species can be overseeded with cool-season or leguminous species to improve forage production, quality or the seasonal distribution of forage production. A well-managed rotational grazing system can improve forage harvest efficiency, reduce consumption of internal parasite larvae and improve animal tameness. Good pasture management requires gathering information, planning and compromising to attain forage production objectives and the flexibility to cope with changes in the weather.

description: Σκοπός της διατριβής αυτής ήταν να διερευνηθεί η επίδραση της διατροφικής προσθήκης λεκιθίνης και/ή ιχθυελαίου, στη θερμική καταπόνηση, τις αποδόσεις και τα ποιοτικά χαρακτηριστικά του αυγού ορνίθων αυγοπαραγωγής. Αφού έγιναν όλες οι απαραίτητες χημικές και εργαστηριακές αναλύσεις, διαπιστώθηκε ότι η συνδυασμένη διατροφική προσθήκη ιχθυελαίου και λεκιθίνης, σε αναλογίες 2% και 0,05% αντίστοιχα, αύξησε σημαντικά τη συνολική αυγοπαραγωγή και το ρυθμό αυγοπαραγωγής. H προσθήκη λεκιθίνης στην τροφή, είχε ως αποτέλεσμα την εμφάνιση μικρού ποσοστού θνησιμότητας, ενώ η προσθήκη ιχθυελαίου και η συνδυασμένη προσθήκη ιχθυελαίου και λεκιθίνης συνέβαλε στη μη εμφάνιση θνησιμότητας.
description: The aim of this study was to determine the effect of lecithin and/or fish oil dietary supplementation on the performance, heat stress and egg quality traits at laying hens. After having made all the necessary chemical and laboratory analysis, it was patently obvious that combined dietary supplementation of lecithin and fish oil at the ratio of 2% and 0,05% respectably, increased the egg production and the egg production rate. The dietary supplementation of lecithin decreased the mortality and the combined supplementation of lecithin and fish oil contributed to zero mortality.

description: The main purpose of this work is to prove characterization theorems for generalized moment functions on groups. According one of the main results these are exponential polynomials that can be described with the aid of complete (exponential) Bell polynomials. These characterizations will be immediate consequences of our main result about the characterization of generalized moment functions of higher rank.

description: Magnon-polarons are coherently mixed quasiparticles that originate from the strong magnetoelastic coupling of lattice vibrations and spin waves in magnetic-ordered materials. Recently, magnon-polarons have attracted a lot of attention since they provide a powerful tool to manipulate magnons, which is essential for magnon-based spintronic devices. In this work, we report the experimental observation of facet-dependent magnon-polarons in epitaxial ferrimagnetic Fe3O4 thin films via spin Seebeck effect measurement. The critical magnetic fields for the magnon-polarons in the (110)- and (100)-oriented Fe3O4 films are 1.5 T and 1.8 T, respectively, which arises from the different phonon velocities along the [110] and [100] directions. As the temperature decreases, the magnon-polarons-enhanced spin Seebeck voltage decreases in both (110)- and (100)-oriented Fe3O4 films, which could be attributed to the enhanced magnon-polarons scattering at elevated temperatures. This work demonstrates the crystal structure engineering in epitaxial magnetic films as a promising route to manipulate the magnon-polarons for future magnon spintronic applications.

description: We propose a correspondence between vertex operator superalgebras and families of sigma models in which the two structures are related by symmetry properties and a certain reflection procedure. The existence of such a correspondence is motivated by previous work on N=(4,4) supersymmetric non-linear sigma models on K3 surfaces and on a vertex operator superalgebra with Conway group symmetry. Here we present an example of the correspondence for N=(4,4) supersymmetric non-linear sigma models on four-tori, and compare it to the K3 case.

description: Stellar ultraviolet (UV) radiation has significant implications on habitability of their exoplanets, yet this radiation is partly unobservable due to interstellar medium absorption. We used the radiative transfer code SSRPM to build stellar models of two M dwarfs and synthesize their UV spectra, particularly focusing on the far-UV and extreme-UV spectra. Our most important findings are that 1) the coronae of two M dwarfs are responsible for more than half of their respective EUV fluxes, and 2) the continuum in the FUV band between 145 and 170 nm is responsible for about half of total emission in this band. Here, we discuss the significance of these results and outline future projects aimed to improve our understanding of solar and stellar UV emission.

description: Η αγροικία στη θέση «Κομπολόι» εντοπίστηκε σε απόσταση περίπου 2,5 χλμ. βορειότερα του Λόφου Κάστρου Πλαταμώνα και 3,5 χλμ. ανατολικά των Λειβήθρων. Πρόκειται για συγκρότημα δύο κτηρίων, μίας οικίας και ενός πιθεώνα, που αναπτύσσονταν γύρω από περίστυλες αυλές. Στον περιβάλλοντα χώρο εντοπίστηκαν υπαίθριες κατασκευές και συστάδες πίθων. Η ίδρυση της εγκατάστασης χρονολογείται μετά τα μέσα του 4ου αι. π.Χ. και η καταστροφή της μετά το α΄ τέταρτο του 3ου αι. π.Χ. Σποραδικές ενδείξεις δραστηριότητας εντοπίζονται μέχρι τα μέσα του 2ου αι. π.Χ. Από το σύνολο των ευρημάτων επιλέχθηκαν να εξεταστούν κεραμικά σκεύη, με σκοπό να διερευνηθεί η χρήση τους σε κάποιο από τα στάδια της παραγωγής ή της επεξεργασίας του γλεύκους. Τα σκεύη διακρίθηκαν, με βάση το σχήμα και το μέγεθος, σε δύο κατηγορίες, τα κοινά καθημερινής χρήσης που εντοπίστηκαν στους χώρους εργασίας και τα ειδικού σχεδιασμού σκεύη. Επικουρικά εξετάστηκαν τα μεταλλικά εξαρτήματα σκευών και τα εργαλεία.
description: Komboloi is an early hellenisticfarmhouse in the area of southern Pieria in Macedonia. The site is located about 3,5 km east of the acropolis of Leivihtra and 2,5 km north of the hill of Platamon-Heraklion.The excavation revealed a farmhouse and a pitheon, dating from the middle 4thto the early 3rd century BC. This paper focuses on the study of plain pottery and tools that were used in a farmhouse equipped with wine facilities. The vessels are distinguishedin two categoriesbased on shape and size, common household ware,deposited in workplaces, and special design shapes, in order to investigate their use inthe wine production. A special chapter is devoted to the study of metal small findsand tools.

description: Η διατήρηση ενός υγιούς εγκεφάλου είναι καθοριστικής σημασίας για την ποιότητα ζωής των ηλικιωμένων και για την διατήρηση της ανεξαρτησίας τους. Η νοητική και σωματική εκπαίδευση έχει δειχτεί πως είναι αποδοτική απέναντι σε παθήσεις και νοητικές καταπτώσεις σχετικές με την ηλικία. Παραμένει άγνωστο όμως το κατά πόσο ένας συνδυασμός των δυο εκπαιδεύσεων θα αποφέρει καλύτερα αποτελέσματα. Συγκρίναμε τα ηλεκτροτομογραφικά δεδομένα 65 ηλικιωμένων που συμμετείχαν στο πρόγραμμα LLM, χωρισμένοι σε 5 ομάδες ανάλογα με την παρέμβαση που ακολούθησαν. Η ηλεκτροτομογραφία πραγματοποιήθηκε με τον αλγόριθμο eLORETA σε γενικό κρανιακό μοντέλο. Τα ΗΕΓ καταγράφηκαν σε κατάσταση ηρεμίας με μάτια κλειστά. Τα αποτελέσματα έδειξαν πως η ομάδα που ακολούθησε την παρέμβαση με συνδυασμό νοητικής και σωματικής εκπαίδευσης είχε στατιστικώς σημαντική διαφορά στην ενεργοποίηση της περιοχής precuneus. Οι υπόλοιπες ομάδες δεν παρουσίασαν στατιστικά σημαντικές διαφορές στην ενεργοποίηση των πηγών του εγκεφάλου. Οι ομάδες ελέγχθηκαν και μεταξύ τους για διαφορές επί των ηλεκτροτομογραφικών δεδομένων και η ομάδα που ακολούθησε μόνο σωματική εκπαίδευση διέφερε σημαντικά από την ομάδα που ακολούθησε και νοητική και σωματική εκπαίδευση στην ίδια περιοχή. Συμπεραίνουμε πως η διαφορά στην συγκεκριμένη περιοχή οφείλεται στην νοητική εκπαίδευση και ο συνδυασμός της με την σωματική επιδρά αθροιστικά και καθιστά την επίδραση στον εγκέφαλο σημαντική.
description: Maintaining a healthy brain is crucial for the quality of life and independence of elders. Cognitive and physical training is shown to be effective againstcognitive decline and age related diseases. The possibility of a synergy additive effect by the combined use of both cognitive and physical training is still unknown. We compared the cerebral activation of 65 elderly individuals that participated at LLM project, divided on 5 groups depended on the intervention they underwent. The cerebral activation was estimated by means of eLORETA algorithm on a general head model. EEG was recorded during resting state eyes closed. The within groups analysis revealed that the group which underwent both cognitive and physical training had statistical significant differences on the activation of the precuneus area. The rest groups didn’t reach statistical significance. The between groups analysis revealed that the group which underwent physical training differed significantly from the both cognitive and physical training group at the same area. We conclude that the difference in cerebral activation of the precuneus area is due to cognitive training whereas the combination with physical training produces a synergy additive effect.
