description: Η συγκεκριμένη Διπλωματική εργασία έχει ως βασικό στόχο να εξετάσει την κατάσταση της εργαζόμενης μνήμης και εάν αυτή επηρεάζεται από κάποιο σοβαρό παιχνίδι. Για να επιτευχθεί ο στόχος, διεξήχθη ένα πείραμα στο οποίο χρησιμοποιήθηκε το σοβαρό παιχνίδι “Memory Pathfinder”. Ο συμμετέχοντας καλείται να απομνημονεύσει μια τυχαία-παραγόμενη διαδρομή σε ένα μεταβλητού εμβαδόν ταμπλό (επιφάνεια), η οποία αρχικά εμφανίζεται στο χρήστη, και στη συνέχεια αυτός αναλαμβάνει να την αναπαράγει. Το μήκος της διαδρομής και το μέγεθος του ταμπλό, είναι ανάλογα της επίδοσης του παίκτη. Στα πλαίσια της παρούσας εργασίας, χρησιμοποιήθηκαν οι τεχνολογίες Unity (Game Engine), MySQL (Data Base), Apache (Web Server) με εγκατεστημένο phpMyAdmin (Σύστημα Διαχείρισης Βάσης Δεδομένων) και η γλώσσα PHP. Από την ανάλυση των αποτελεσμάτων του πειράματος συμπεραίνεται πως το παιχνίδι επιτυγχάνει τον αντικειμενικό στόχο. Συγκεκριμένα, κατά τη διεκπεραίωση του πειράματος, ο μέσος όρος της χωρητικότητας της εργαζόμενης μνήμης βελτιώθηκε κατά μία μονάδα. Η βελτίωση αυτή σε ατομικό επίπεδο σημειώθηκε σε όλους τους συμμετέχοντες εκτός από δύο περιπτώσεις όπου ήδη η τιμή της χωρητικότητας της εργαζόμενης μνήμης ήταν υψηλή
description: The present Degree Thesis has as primary objective to examine the status of the working memory and if it is influenced by a serious game. To achieve the purpose, an experiment was carried out, on where the serious game “Memory Pathfinder” was used. The participant has to memorize a random-generated path in a variable grid (surface) area. The path is initially illustrated, and then the user has to repeat it. The path length along with the grid size is proportional to the player’s performance. In the context of the present project, technologies Unity (Game Engine), MySQL (Data Base), Apache (Web Server) with phpMyAdmin installed (Data Base Management System) and PHP language were used. From the analysis of the experiment’s results, it is concluded that the game accomplishes its objective. Particularly, after the conclusion of the experiment, the average of the working memory’s capacity improved by one unit. This improvement in individual level was noted in all participants except of two cases where the value of the working memory’s capacity was already high

Η διδακτική πρόταση «e-STEEM» αποτελεί ένα συνδυασμό των αρχικών της διαδικτυακής μάθησης (e-), του STEM, και της ψυχαγωγίας (Entertainment), όπου στηρίχθηκε ο σχεδιασμός των δραστηριοτήτων και αποσκοπεί σε μαθησιακά αποτελέσματα όπως η δημιουργία κινήτρου για ενασχόληση με τις φυσικές επιστήμες, η ενεργοποίηση της προϋπάρχουσας γνώσης, η διευκόλυνση της μαθησιακής διαδικασίας και η συσχέτιση της παραγόμενης γνώσης με καταστάσεις της καθημερινής ζωής. Ο αρχικός σχεδιασμός της έρευνας περιλάμβανε την μελέτη μαθητών μέσω ερωτηματολογίων pre-test και post-test, με σκοπό να διερευνηθούν τα γνωσιακά, μεταγνωσιακά και συναισθηματικά αποτελέσματα που προκύπτουν από την εφαρμογή της προτεινόμενης παρέμβασης. Ωστόσο, ο σκοπός της παρούσας έρευνας αναπροσαρμόστηκε, στα πλαίσια της πανδημίας του Covid-19 και των κλειστών σχολείων. Με τις αναπροσαρμογές αυτές η τελική μορφή της έρευνας εστιάζει στη διερεύνηση της μεταβολής στις απόψεις των εκπαιδευτικών αναφορικά με τη διδασκαλία STEM, μετά το πέρας της προτεινόμενης διαδικτυακής διδασκαλίας, μέσω τηλεκπαίδευσης, την οποία η πανδημία καθιέρωσε
description: The purpose of this thesis is the design of an online platform which includes a series of activities that promote inquiry learning for learning Science and is addressed to students of the fifth and sixth grade of primary school. The educational proposal entitled “e-STEEM” is based on the principles of online learning (e-), STEM education and Entertainment Education (E). Our aim is to evaluate the impact of this educational proposal on students’ motivation, the stimulation of previous knowledge, the facilitation of the learning process, the correlation of the knowledge produced with situations of everyday life and the increase of the probability that the student will recall information stored in the memory about the learning subject. The initial research design included evaluation of the changes on students’ cognitive and metacognitive domain and through their attitudes as well, via pre-test and post- test questionnaires. Nevertheless, research purpose had to be redesigned due to Covid-19 restrictions and measures that the temporary shutdown of schools dictated. With these adjustments this research final aim is to evaluate the impact of the proposed teaching method through teachers attitudes on STEM education, in the context of distance teaching, which pandemic established

description: The brown algae (Phaeophyceae) are a group of multicellular heterokonts that are ubiquitous in today’s oceans. Large brown algae from multiple orders are the foundation to temperate coastal ecosystems globally, a role that extends into arctic and tropical regions, providing services indirectly through increased coastal productivity and habitat provisioning, and directly as a source of food and commercially important extracts. Recent multi-locus and genome-scale analyses have revolutionized our understanding of the brown algal phylogeny, providing a robust framework to test evolutionary hypotheses and interpret genomic variation across diverse brown algal lineages. Here, we review recent developments in our understanding of brown algal evolution based on modern advances in phylogenetics and functional genomics. We begin by summarizing modern phylogenetic hypotheses, illuminating the timescales over which the various brown algal orders diversified. We then discuss key insights on our understanding of brown algal life cycle variation and sexual reproduction systems derived from modern genomic techniques. We also review brown algal speciation mechanisms and the associated biogeographic patterns that have emerged globally. We conclude our review by discussing promising avenues for future research opened by genomic datasets, directions that are expected to reveal critical insights into brown algal evolution in past, present, and future oceans.
A hermeneutic phenomenological study to explore postgraduate nursing students' lived experience of workplace support to apply learning in practice
Creators: name: Buckby, Anna
Publisher: name: Zenodo
Year: 2025

description: Strategic policies were identified from government, professional and healthcare organisations for postgraduate nurse education (PGNE) to support the capacity and capability of the nursing workforce to meet healthcare needs. However, iterative literature reviews throughout my professional doctorate identified limited research and understanding relating to postgraduate nursing students’ (PGNS) experiences of workplace support to apply learning in practice (ALiP).Therefore, the overarching aim of my hermeneutic phenomenological study was to make an original contribution to knowledge relating to PGNS experiences of workplace support to ALiP. The methodological framework is underpinned by a constructionist ontology, interpretivist epistemology and hermeneutic phenomenology that assume multiple realities and truths. Justification for the framework and methodological decisions is underpinned by the aim of understanding the subjective, lived experiences of PGNS. Following university ethical approval for the study, relevant gatekeeper permissions were sought to purposefully recruit voluntary participants enrolled on a range of postgraduate nursing programmes. The study’s inclusion and exclusion criteria aimed to ensure participation of PGNS with experiences of undertaking postgraduate education while working in nursing practice.Individual audio recorded telephone interviews were undertaken to collect and transcribe an accurate description of the verbal sharing of the participants’ PGNS experiences. Data interpretation of parts (individual transcriptions) and the whole (collective transcriptions) was guided by the hermeneutic spiral, frameworks for interpretation and rigour, and my fore-structures of understanding. Within this thesis findings are presented as offerings inclusive of rich, in-depth interpretation and analytical discussion with anonymous crafted extracts to bring to life the participants’ subjective lived experiences. The offerings chapters critically explore the phenomena revealed through data interpretation to illuminate furtherunderstanding and meaning of PGNS experiences of workplace support to ALiP, and transparently discuss methodological strengths and limitations. The outcomes of my research aim to provide an opportunity for relevant professional colleagues to further understanding, knowledge, research and practice relating to PGNS experiences of workplace support to ALiP.

description: Despite falling per capita incomes in these countries, globalization has probably not led to a deterioration of food security in Russia, Ukraine and Belarus. Measures of food inadequacy in these countries are significantly lower than in developing countries. The majority of the most severe nutritional problems in the Russian Federation'overweight and obesity in adults and various micronutrient deficiencies in both adults and children'are the same as they were during the Soviet era and are linked to diets. For children, these are low rates of breast feeding, possible deficiencies in weaning practices, a lack of vitamin C and iron deficiencies. For adults, the most severe problems are caused by a high-fat, high cholesterol, low fiber diet. This includes low consumption of fruits and vegetables, high consumption of dairy and meat and sugar and higher than recommended alcohol (for males) consumption.

Are universal "anomalous" properties of glasses at low temperatures truly universal?

description: The specific heat Cp and other properties of glasses (ranging from amorphous solids to disordered crystals) at low temperatures, are well known to be markedly different from those in fully-ordered crystals. For decades, this qualitative, and even quantitative, universal behavior of glasses has been thoroughly studied. However, a clear understanding of its origin and microscopic nature, needless to say a closed theory, is still lacking. To shed light on this matter, I review the situation in this work, mainly by compiling and discussing measured low-temperature Cp data of many glasses and disordered crystals, as well as highlighting a few exceptions to that "universality rule". Thus, one can see that, in contrast to other low-temperature properties of glasses, the magnitude of the "glassy" Cp excess at low temperature is far from being universal. Even worse, some molecular crystals without a clear sign of disorder exhibit linear coefficients in Cp larger than those found in many amorphous solids, whereas a few of the latter show negligible values.

description: This paper deals with consumption dynamics and its effects on poverty. An econometric model is proposed in which changes in consumption across time are seen as fluctuations around the level of consumption that each family can sustain in the long term. The advantages of this approach are twofold. First, it allows identification of the main determinants of changes in poverty. Second, it allows distinguishing between chronic and transient poverty, by defining as chronically poor those households whose level of consumption sustainable in the long term lies below the poverty line. This definition of chronic poverty represents a change with respect to previous works on the subject, in which chronic poverty is defined with reference to the average level of consumption (or income) observed at the family level along the temporal interval of the panel. The innovation of our proposal lies in the fact that all the information from the panel data set, relative to all households, is exploited in order to identify which level of consumption each family is tending toward through time. Furthermore, our definition of chronic poverty allows one to identify four different groups of families that differ by level of observed consumption and by potential to generate income for consumption. The four groups are characterized by different incidences of chronic and transient poverty, and hence require different kinds of anti-poverty policies and public support. Data from two Living Standards Measurement Surveys (LSMS) carried out by the World Bank in Nicaragua in 1998 and 2001 are used, while accounting for potential problems of attrition.

description: In recent years, significant progress has been made in developing more accurate and efficient machine learning algorithms for segmentation of medical and natural images. In this review article, we highlight the imperative role of machine learning algorithms in enabling efficient and accurate segmentation in the field of medical imaging. We specifically focus on several key studies pertaining to the application of machine learning methods to biomedical image segmentation. We review classical machine learning algorithms such as Markov random fields, k-means clustering, random forest, etc. Although such classical learning models are often less accurate compared to the deep learning techniques, they are often more sample efficient and have a less complex structure. We also review different deep learning architectures, such as the artificial neural networks (ANNs), the convolutional neural networks (CNNs), and the recurrent neural networks (RNNs), and present the segmentation results attained by those learning models that were published in the past three years. We highlight the successes and limitations of each machine learning paradigm. In addition, we discuss several challenges related to the training of different machine learning models, and we present some heuristics to address those challenges.

Large farm debt in Ukraine

Year: 2003
Subjects: Farm Management

description: The present study analyzes the nature of Ukrainian farm debt by investigating whether the debt servicing problem of Ukrainian farms is more of a debt problem or a net income problem. Net income generation appears to be the more important underlying problem behind the debt problem. Second, the study recounts the main reasons for apparent farm losses in Ukraine. This analysis suggests that low profits are a result of public policies that reduce incentives for profit making, farm production of livestock products at a loss and lack of restructuring. The study concludes that the debt servicing problem of Ukrainian farms leaves them unable to utilize market instruments to secure seasonal financing and is the primary justification for the presence of the Ukrainian government in financing seasonal input supplies. Such financing creates a substantial burden on the state budget, and ultimately on taxpayers. It also leads to sizeable State claims on commodity markets that are similar to a continuation of the state order system for grain that was discontinued after 1997.

description: The aim of this research was to assess, under laboratory conditions, how the accumulation of four heavy metals (HMs) (lead (Pb), copper (Cu), nickel (Ni), and zinc (Zn)), prepared as aqueous solutions from 1 μM to 1 mM, affected biochemical and physiological parameters of Amaranthus retroflexus seedlings. Seedlings showed considerably high resistance to all investigated HMs and no significant oxidative stress in leaves. After chronic exposure to high doses of any of the HMs, seedlings remained viable, but with slightly slower axial growth. We propose the use of biochemical indices (lipid peroxidation (LPO) intensity; level of total peroxides) as criteria to assess the adaptive potential of amaranth plants to HMs. These indices had very high correlation coefficients (r) with the accumulation of HMs in A. retroflexus roots, stems and leaves: 0.86–0.89 for malone dialdehyde (MDA) content for Ni and Zn, and 0.79–0.94 for total peroxides (for Cu, Pb, and maximum in Ni). At 1 mM of any HM, seedlings accumulated Pb and Ni at levels of HM-hyperaccumulating species. If soil is contaminated (in terms of maximum permissible concentration, MPC) by Pb (8.2 ± 2.2 MPC) or Ni (3.5 ± 1.0 MPC) (equivalent to 1 mM of the HM in solution), A. retroflexus is a strong candidate for the phytoremediation of Pb- and Ni-contaminated soils.

description: In this study, the pseudo wastewater containing Zn, Fe, Cu ions was clean-up by a combination of physical adsorption onto activated carbon medium and phytoaccumulation using Acrostichum aureum Linn. plants. The adsorption capability of the activated carbon for the Fe, Cu, and Zn ions was 3.05, 3.72, and 2.85 mg·g − 1, respectively, at the saturation. The phytoaccumulation performance was proved by analyzing the individual residual ash collected after pyrolysis up to 1000 °C of the leaf, stem, and root of the plants. Thermal analyses of thermogravimetry data showed that the weight of the residual ash of the phytoremediated leaf, stem, and root of the plants was 37.0, 19.0, and 65.7 wt.%, respectively. Energy-dispersive X − ray spectroscopy determined the amount of Fe element in the residual ash of phytoremediated root is 7.05 wt.%, while that of the initial root is 1.18 wt.%. Conclusively, it can be proved that combining physical and biological processes is feasible to treat wastewater containing metal ions.

description: We argue that several empirical constraints strongly restrict parameters of the effective microscopic spin model describing $α$-RuCl$_3$. In particular, such constraints dictate a substantial \emph{positive} off-diagonal anisotropic coupling, $Γ^\prime\!>\!0$, not anticipated previously. The renormalization by quantum fluctuations allows to reconcile larger values of the advocated bare parameters with their earlier assessments and provides a consistent description of the field evolution of spin excitations in the paramagnetic phase. We assert that large anisotropic terms inevitably result in strong anharmonic coupling of magnons, necessarily leading to broad features in their spectra due to decays, in accord with the observations in $α$-RuCl$_3$. Using duality transformations, we explain the origin of the pseudo-Goldstone mode that is ubiquitous to the studied parameter space and is present in $α$-RuCl$_3$. Our analysis offers a description of $α$-RuCl$_3$ as an easy-plane ferromagnet with antiferromagnetic further-neighbor and strong off-diagonal couplings, which is in a fluctuating zigzag ground state proximate to an incommensurate phase that is continuously connected to a ferromagnetic one.

The present master’s thesis, entitled “Money as a medium in contemporary literature: Uwe Timm’s Novel Kopfjäger und Paul Divjak’s Novel Kinsky” addresses these questions and aims to examine money as a medium in the contemporary German literature. The methodological approach is based on sociological theories and comparative textual analysis. The master’s thesis is structured in two parts: The first part is the theoretical framework, which deals with the sociological studies of Marcel Mauss, François Simiand, Michel Foucault, Felix Martin, Pierre Bourdieu and others. The second part shows how the medium “money” can be interpreted in the German literary texts of Uwe Timm Kopfjäger and Paul Divjak Kinsky

description: We present results from in-flight calibration of the High Energy Transmission Grating Spectrometer (HETGS) on the Chandra X-ray Observatory. Basic grating assembly parameters such as orientation and average grating period were measured using emission line sources. These sources were also used to determine the locations of individual CCDs within the flight detector. The line response function (LRF) was modeled in detail using an instrument simulator based on pre-flight measurements of the grating alignments and periods. These LRF predictions agree very well with in-flight observations of sources with narrow emission lines. Using bright continuum sources, we test the consistency of the detector quantum efficiencies by comparing positive orders to negative orders.

Rural finance without markets in Ukraine, 1991-2000

description: Three institutional pillars form the foundations of sustainable financial markets: The existence of a pool of profitable and diverse rural clients with the ability to service loans, well-run financial institutions which are financially self supporting and an enabling policy environment. Ukraine has not been successful in developing robust rural financial markets because it has consistently undermined these three institutional pillars through soft government-provided or government-subsidized directed credits that have had an overwhelming role in rural policies in the post- Soviet period. Instead of a pool of profitable clients, the Ukrainian countryside is dominated by unprofitable farm enterprises which employ the overwhelming majority of rural residents. Second, financial institutions serving agricultural enterprises in Ukraine have largely distributed government directed soft credit at unsustainable interest rates to financially troubled farms in order to cover losses. Third, there has been abiding opposition to policies to ensure clear property rights, enforceable contracts and transparent farm restructuring and privatization, because such policies would imply the dissolution of large scale farms which are the object of most rural policies. Instead of creating sustainable rural financial markets, Ukrainian policies were instrumental in causing a substantial accumulation of bad debt by agricultural enterprises by the end of the 1990s. Partly as a response to this problem, the Government of Ukraine privatized agricultural enterprises in a four month period in 2000 and wrote off or rescheduled much of farm debt. The government also subsequently changed its main form of financing agricultural input markets from direct state involvement to substantial credit subsidies. In these policy changes the government of Ukraine adhered to its well-established legacy of addressing the symptoms of financial problems without altering fundamental causes.

description: We investigate the use of a narrow-band DDO51 filter for photometric identification of cool white dwarfs. We report photometric observations of 30 known cool white dwarfs with temperatures ranging from 10,000 K down to very cool temperatures (<3500 K). Follow-up spectroscopic observations of a sample of objects selected using this filter and our photometric observations show that DDO51 filter photometry can help select cool white dwarf candidates for follow-up multi--object spectroscopy by rejecting 65% of main sequence stars with the same broad--band colors as the cool white dwarfs. This technique is not selective enough to efficiently feed single--object spectrographs. We present the white dwarf cooling sequence using this filter. Our observations show that very cool white dwarfs form a sequence in the r-DDO vs. r-z color--color diagram and demonstrate that significant improvements are needed in white dwarf model atmospheres.

The concept of legal literacy amongst educators in Canada
Creators: name: Peña Carranco, Laura Elisa
Publisher: name: The University of British Columbia

description: The purpose of this paper is to show that both federal and provincial legislations directly impact the education profession, thus making it essential for educators to be legally literate. I intend to achieve this by thoroughly exploring the concept of legal literacy amongst educators. I take into account the legal framework that hold their profession to account, while I attempt to contribute to the understanding of what it means for an educator in Canada to be legally literate. I do not only seek to provide an understanding of the legal bodies that regulate the teaching profession, even though that is a great starting point, but to reflect on the importance of educators being knowledgeable of these legal bodies and for what purposes. The paper is organized in four main sections each one with its own subsections. In the first section I analyse the definition of literacy, the meaning legal has in the concept of legal literacy, and its role in the educational field. Section two is where I address educators’ understandings and level of legal literacy. In section three I explore the importance of having legally literate educators and I include some recommendations that might contribute to improving educators’ level of legal literacy. Finally, I conclude in section four with a reflection on the importance it has for educators to be legally literate and to see the process of becoming legally literate as an active one.

description: A weakly-interacting massive particle (WIMP) is perhaps the most promising candidate for the dark matter in the Galactic halo. The WIMP detection rate in laboratory searches is fixed by the cross section for elastic WIMP-nucleus scattering. Here we calculate the contribution to this cross section from two-nucleon currents from pion exchange in the nucleus, and show that it may in some cases be comparable to the one-nucleon current that has been considered in prior work, and perhaps help resolve the discrepancies between the various direct dark-matter search experiments. We provide simple expressions that allow these new contributions to be included in current calculations.

Food insecurity, poverty and agriculture: a concept paper

Subjects: Food Security and Poverty

description: This paper argues for a twin-track approach to hunger and poverty reduction that combines measures to promote rural development through growth in agriculture and rural off-farm activities with measures to provide direct and immediate access to food for the most needy. The paper begins with an exposition of the concepts of food insecurity and poverty and shows that the majority of the hungry and poor in developing countries still live in rural areas. It then documents the substantial economic costs of hunger to show that direct action against hunger can itself contribute to poverty reduction. It goes on to argue that if the income from agricultural growth is spent locally and promotes growth in rural off-farm activities, this can have a strong impact on the incomes of the poor. Evidence is presented to substantiate this argument. The paper concludes by discussing the implications of the twin-track approach for anti poverty strategies.

Quantum Mechanics at Planck's scale and Density Matrix

description: In this paper Quantum Mechanics with Fundamental Length is chosen as Quantum Mechanics at Planck's scale. This is possible due to the presence in the theory of General Uncertainty Relations. Here Quantum Mechanics with Fundamental Length is obtained as a deformation of Quantum Mechanics. The distinguishing feature of the proposed approach in comparison with previous ones, lies on the fact that here density matrix subjects to deformation whereas so far commutators have been deformed. The density matrix obtained by deformation of quantum-mechanical density one is named throughout this paper density pro-matrix. Within our approach two main features of Quantum Mechanics are conserved: the probabilistic interpretation of the theory and the well-known measuring procedure corresponding to that interpretation. The proposed approach allows to describe dynamics. In particular, the explicit form of deformed Liouville's equation and the deformed Shrödinger's picture are given. Some implications of obtained results are discussed. In particular, the problem of singularity, the hypothesis of cosmic censorship, a possible improvement of the definition of statistical entropy and the problem of information loss in black holes are considered. It is shown that obtained results allow to deduce in a simple and natural way the Bekenstein-Hawking's formula for black hole entropy in semiclassical approximation.

description: This pot experiment analyzed the use of Brassica napus, Elymus elongatus and Zea mays in the removal of Cd2+ Co2+ and Ni2+ from the soil. The utility of the plants under study for phytoremediation was analyzed based on the biomass of the aboveground parts and roots and the accumulation of metals, bioaccumulation, bioconcentration and translocation capability in the above-ground parts and roots. The effect of heavy metals on the soil enzyme activity and soil physicochemical properties was also determined. Among the species under study, only E. elongatus was found to be suitable for Cd2+ phytoextraction, whereas E. elongatus and Z. mays proved to be suitable for phytostabilisation of Cd2+ and Co2+ because the criterion of the accumulation of metals in the roots at a sufficient level was fulfilled. The index of bioaccumulation in roots was greater than one. Both plant species met the second condition which determined the utility for phytostabilisation, as since the transport of Cd2+ Co2+ and Ni2+ from the roots to the above-ground parts was limited.
title: The effect on unemployment of selected changes in working time patterns
Creators: name: Keith, Ronald L G
Publisher: name: The Open University
Year: 1985

description: The hypothesis, that unemployment can he greatly reduced at an acceptable economic cost to the nation by decreasing the total hours people spend at work during their lifetimes, is examined. Preferences related to work and leisure were elicited via two surveys from 11O5 people below the qualifying age for State pensions and 147 people receiving the pensions in the Reading area. It is argued that it is unlikely that unemployment will fall appreciably in future years without introducing some form of job sharing. Using the results of the surveys an analysis is carried out of the social and economic implications of introducing earlier retirement for men, and various methods of reducing the number of working days per year for men and women. Calculations show that voluntary retirement for men from the age of 60 could release about 600,000 jobs for the unemployed at a cost of about 0.2% of the 1984 Gross Domestic Product (GDP). It is suggested that most of the remaining non-structural unemployment could be eliminated by a special form of job sharing at a cost of about 2% of the 1984 GDP. Further programmes of research are proposed to investigate specific aspects of the recommended policies which have evolved from this more general study.

description: Purpose of this study: This paper has been prepared with the aim of critically evaluating the Greek therapeutic prescribing protocol for ulcerative colitis. Methods: The evaluation was carried out after examination and comparison of international protocols for the treatment of ulcerative colitis and taking into account the results of evidence-based research and studies. Results: The Greek protocol for ulcerative colitis is in line with international guidelines. It would be helpful to consider adding additional drugs to the drug arsenal, clarifying some of the proposed regimens, and including some prognostic criteria that can help the prescriber assess the course and severity of the disease. Conclusions: The Greek therapeutic protocol is characterized by good structure and scientifically substantiated content, following the principles of evidence-based medicine. However, there are some points that need consideration
Το συναίσθημα της χαράς στον απόστολο Παύλο κατά την ερμηνευτική του κατανόηση από τον άγιο Νικόδημο τον Αγιορείτη

description: Σκοπός της παρούσης εργασίας είναι η μελέτη του συναισθήματος της χαράς στις επιστολές του αποστόλου των εθνών Παύλου κάτω από το πρίσμα της ερμηνείας του αγίου Νικοδήμου του Αγιορείτου. Αρχικά διευκρινίζονται οι έννοιες του συναισθήματος και της χαράς, ενώ ακολούθως εξετάζεται ο όρος «χαρά» στην Αγία Γραφή. Προχωρώντας, γίνεται εκτενέστερη αναφορά στον υπό εξέταση όρο στις παύλειες επιστολές, όπου συναντάται πολλάκις. Για τον απόστολο Παύλο η χαρά δεν είναι ένα απλό συναίσθημα, αλλά μία σταθερή και συνεχής κατάσταση. Νοείται ως δωρεά του Αγίου Πνεύματος και έχει εσχατολογική σημασία, ως πρόγευση της τελείας χαράς που θα έρθει μετά την Δευτέρα Παρουσία. Η αντίληψη αυτή εντοπίζεται και στην πατερική παράδοση. Αντιπροσωπευτικό παράδειγμά της αποτελεί ο άγιος Νικόδημος ο Αγιορείτης, ο οποίος στα εξηγητικά του κείμενα προσεγγίζει τη χαρά στις παύλειες επιστολές ως ένα βασικό και απαραίτητο συστατικό στοιχείο της χριστιανικής ζωής. Για τον άγιο Νικόδημο, όπως και για τον απόστολο Παύλο, η χαρά που προέρχεται από τον Χριστό είναι η μόνη αληθινή, διαρκής και πλήρης που μπορεί να υπάρξει, ενώ το πλέον χαρμόσυνο γεγονός στην ιστορία είναι αναμφισβήτητα η Ανάσταση, στην οποία πραγματώνεται η ελπίδα της σωτηρίας των ανθρώπων, σηματοδοτείται η οριστική νίκη επί του θανάτου και ανοίγονται οι πύλες της Βασιλείας του Θεού
description: The purpose of this thesis was to study the emotions and specifically that of Joy, in the Pauline Epistles and their exegesis from St. Nicodemus the Hagiorite. At first we tried to define and explain the concepts of emotion in general and of joy in particular, according to the findings of Psychology, Philosophy and other disciplines. After that we discussed the term “Joy” in the Bible with a specific focus on the term inside the Pauline Epistles. The term is found many times in the Epistles. For Paul joy is not just an emotion, but a stable and permanent condition. This kind of joy is viewed as a gift from God to His People and carries a deeply eschatological meaning, as it is considered a kind of promise for the fullness of joy that is to be enjoyed after the Second Coming of Christ. This notion of joy is found also in the Patristic tradition. A characteristic example of this tradition is St. Nicodemus the Hagiorite who in his exegesis of the Epistles approaches Joy in Paul as an essential ingredient, as a sine qua non of the Christian life. For St. Nicodemus, following Paul, Joy that is coming from Christ is the only kind of Joy that can be truly permanent and fulfilling. Finally, we stress the point that for the Apostle, as well as St. Nicodemus the greatest cause and source of Joy for humans is the Resurrection of Jesus
