description: We present the results of a study of young unresolved stellar groupings (clusters, OB associations, and their complexes) associated with HII regions, based on the coupling of spectroscopic, photometric and Hα spectrophotometric observations of star formation regions. Along with our own observations, we use a part of the spectroscopic and Hα data from the literature and open databases. The study is based on the catalogue of 1510 star formation regions with ages ~10-20 Myr in 19 spiral galaxies, compiled by us earlier. We study the morphology of stellar groupings and their relation with the associated Hα emission region. Extinctions, gas chemical abundances, and sizes of star formation regions are measured. Using numerical SSP models computed for metallicities fixed from observations to intrinsic colours of the studied star formation regions, we estimated ages and masses of stellar population of 400 young stellar groupings. Different relations between observational and physical parameters of the young stellar population in star formation regions are discussed.

description: Background: - Trachoma is still a widespread disease that causes blindness in many developing countries. Disease transmission occurs primarily between children and the women who care for them. There are currently 590 million people at risk from blinding trachoma, 150 million people with active trachoma, 10.6 million people with Trichiasis, and 5.9 million people with irreversible blindness due to trachoma. In Ethiopia the national blindness prevalence is estimated to be 1.25% and more than 900,000 persons are believed to be blind. Objective :- This study is designed to assess the prevalence of active trachoma among young children in relation to the implementation of SAFE strategy in their living area. Methods :- A comparative cross sectional study to assess the prevalence of active trachoma among young children, with a total of 1244 children included in the study. The sampling technique was multi-stage sampling by randomly selecting six kebeles from Ebinat woreda, and four kebeles from East Belesa woreda. The selected kebeles were divided into 144 villages, and among these 15 villages were selected by simple random sampling methods. 796 households with children under ten years in the selected villages were interviewed, and 1244 children were examined for the presence of active trachoma disease. This study took place between October and December 2004. Result In this study the prevalence of active trachoma in Ebinat woreda, where the SAFE strategy had been implemented, was 32%, and in East Belesa woreda, where the SAFE strategy was not implemented, prevalence was 56.9%. Awareness of the community for the preventions of trachoma in the area where SAFE strategy implemented was higher than non-implemented area. But in practice there were no differences except that face washing was more practiced in the area of SAFE strategy implemented. Conclusion The prevalence of active trachoma was lower in the area where SAFE strategy was implemented but it was higher in children residing in the area where SAFE strategy was not implemented. Infrequent face-washing habit was the strongest predictor of active trachoma. Recommendation Efforts should be concentrated on improving face-washing habit of children to reduce the magnitude of trachoma. Government and non-government organizations, planners and health policy makers should give a special emphasis for the role of SAFE strategy on trachoma control program.

description: Currently, the meteor shower part of Meteor Data Center database includes: 112 established showers, 563 in the working list, among them 36 have the pro tempore status. The list of shower complexes contains 25 groups, 3 have established status and 1 has the pro tempore status. In the past three years, new meteor showers submitted to the MDC database were detected amongst the meteors observed by CAMS stations (Cameras for Allsky Meteor Surveillance), those included in the EDMOND (European viDeo MeteOr Network Database), those collected by the Japanese SonotaCo Network, recorded in the IMO (International Meteor Organization) database, observed by the Croatian Meteor Network and on the Southern Hemisphere by the SAAMER radar. At the XXIXth General Assembly of the IAU in Honolulu, Hawaii in 2015, the names of 18 showers were officially accepted and moved to the list of established ones. Also, one shower already officially named (3/SIA the Southern iota Aquariids) was moved back to the working list of meteor showers. At the XXIXth GA IAU the basic shower nomenclature rule was modified, the new formulation predicates \The general rule is that a meteor shower (and a meteoroid stream) should be named after the constellation that contains the nearest star to the radiant point, using the possessive Latin form". Over the last three years the MDC database was supplemented with the earlier published original data on meteor showers, which permitted verification of the correctness of the MDC data and extension of bibliographic information. Slowly but surely new database software options are implemented, and software bugs are corrected.

description: In the context of current surgical techniques, the classification of 3D organs based on two-dimensional cross-sections is a decisive and still challenging task. The goal of this paper is to explore an approach to address this problem. By this means, the expectation is to go further in the direction of patient-specific surgery. Based on two-dimensional image data, we analyze different clustering results assuming specific evaluation criteria. By doing so, a determination of the most appropriate number of clusters is possible. As an example, we use this method to classify the shape of the neck of the pancreas of humans, which is relevant for different types of distal pancreatectomy. Hereby, scaling issues of the available data are a key point. Therefore, an overall protocol needs to care for comparable data.

description: In 1966, Beijing, during the Red Guards movement, which resembled quasi-anarchy, a political commentary, "On Family origin," was posted in the streets and alleys by its author, a 24-year-old worker, Yu Luoke (遇 罗克). The main argument of his political commentary was against discriminatory policies based on family origin. In Mao-era China, especially since the 1960s, everyone was divided into different classes based on their family origin (Jiating chushen) and personal manifestation (Geren biaoxian). If the regime considered someone’s family origin politically discredited, this person would be discriminated against in terms of employment, university admissions, and access to other social resources. Many young people who did not come from powerful families supported Yu's criticism of these practices, creating significant social influence during the early period of the Cultural Revolution. Yu was arrested and executed in 1970 as a rebel. This study aims to answer several questions: What ideas, perceptions, and life experiences drove the social movement that Yu started with public writing as the primary means? Why was Yu killed as a rebel instead of being supported by the CCP leadership, led by Mao Zedong, when both Yu and the CCP leadership opposed discrimination based on someone's family origin in principle? What endogenous contradictions and paradoxes of the Chinese Communist regime are reflected in the social movement of Yu and his eventual execution in the context of the 1960s and 1970s? Furthermore, how did such endogenous contradictions and paradoxes influence and relate to other civil disobedience movements in post-Mao China?

Year: 2007

description: Background: Occupational injuries pose a major public health and development problem. At present the problem of occupational injuries in work place is increasing in many developing countries including Ethiopia, mainly caused by unsafe work environments or human factors. Objectives: This study was aimed to determine the magnitude of occupational injuries and identifying factors related to this injury among workers. Methods: Cross-sectional study design was employed to assess occupational injuries among Tendaho Agricultural Development S.C workers, Afar Regional State. The enterprise was first stratified by working departments and working sections. A total of 810 workers were involved in the study based on proportional allocation to size. Study subjects were selected using simple random sampling technique. Data collection was made using pre-tested questionnaire. Work environment observation, physical examination, and reviewing injury records were also employed to complement self reported information. Results: The overall occupational injury prevalence rate was 783 per1000 exposed workers per year. Seventy (11%) injured workers were hospitalized. Most (90%) of hospitalization was more than 24 hours. One death was also reported in the last 12 months. A total of 6153 work days were lost, being 11.4 days lost on average per an injured worker. Working more than 48 hours per week [AOR: 8.27, 95% CI:(4.96-13.79)], absence of health and safety training [AOR: 2.87, 95% CI: (1.02-8.06)], sleeping disorder [AOR: 1.64, 95% CI: (1.12- 2.41)], alcohol drink [AOR: 1.72, 95% CI: (1.06-2.80)], job dissatisfaction [OR: 1.83, 95% CI: (1.30-2.58)] and absence of protective devices [OR: 3.18, (1.40-7.23)] were significant factors to occupational injuries. Conclusion: Working more than 48 hours per week, absence of health and safety training, sleeping disorder, alcohol drink, job dissatisfaction and absence of protective devices increases the risk of occupational injuries. Ongoing health and safety information and/or training, periodic supervision, and occupational health and safety services above all should be emphasized to promote health and safety conditions of the worker.

description: This paper provides a basic overview of the legal treatment of direct active euthanasia in countries where it is permitted and already in place (Netherlands, Belgium, Luxembourg, Canada, Australia, Colombia, Spain). In addition, it includes an extensive reporting of countries where only medically assisted suicide is legal, through the presentation in brief of relevant legislation or court decisions. Special reference is made to the relevant case law of the European Court of Human Rights. The current increased attention around euthanasia is demonstrated by the presentation of recent legislative initiatives or jurisprudential developments in other countries, which raise the issue at the heart of modern medical, legal and social interest, while launching a particularly intense dialogue.

description: The aim of the present thesis is the study of the principle of the suspensive effect of the legal remedies, namely in the form of the appeal and the cassation appeal against judicial decisions in the context of the criminal proceedings, moreover the thesis highlights the importance of the aforementioned notion on a procedural level. The reasons that led to its establishment are initially set out, then the essay extensively examines the respective provisions of the Criminal Procedure Code, as amended by Law No 4620 of 2019 and Law No 4637 of 2019, as well as the formal and material prerequisites for the applicability of those rules, which are approached through a theoretical and a jurisprudential analysis. Furthermore, the study presents the interpretation difficulties that arise due to the co-existence in our criminal justice system of different legitimate purposes, on the one hand the ones that comply with the anti-crime policy, on the other hand the ones that align with the protection of citizens from abusive litigation tactics.

description: Deterministic tourist walk (DTW) has attracted increasing interest in computer vision. In the last years, different methods for analysis of dynamic and static textures were proposed. So far, all works based on the DTW for texture analysis use all image pixels as initial point of a walk. However, this requires much runtime. In this paper, we conducted a study to verify the performance of the DTW method according to the number of initial points to start a walk. The proposed method assigns a unique code to each image pixel, then, the pixels whose code is not divisible by a given $k$ value are ignored as initial points of walks. Feature vectors were extracted and a classification process was performed for different percentages of initial points. Experimental results on the Brodatz and Vistex datasets indicate that to use fewer pixels as initial points significantly improves the runtime compared to use all image pixels. In addition, the correct classification rate decreases very little.

description: HIV/AIDS has seriously affected the well-being of adolescents in Ethiopia and has posed serious concern for their parents. However, parental and community involvement in HIV prevention and control activities has been limited due to top-down approach adapted in the program. To assess the role of families and communities in the prevention and control of HIV/AIDS among adolescents. A cross sectional community based study was conducted in Jimma town from January to February 2004 using a mixture of quantitative and qualitative research methods. A total of 602 parents were randomly included in the study. Majority of parents agreed to most of the questions used to assess the risk reduction potentials but only 121(48.4%) fathers and 149(42.6%) mothers agreed with regard to the role of parents in the promotion of condoms use among sexuality active young adults. On the other hand the responses of the study subjects were below 50% for most of the vulnerability and impact reduction potential questions. Education and family income were found to be determinant factors for the perceived risk, vulnerability and impact reduction potential (p <0.05). Four hundred and sixty two (76%) and 358(59.6%) of parents reported that they made discussion about HIV/AIDS and sexuality with their children respectively. Yet only 130(21.7%) of the parents reported that they had ever advice the use of condoms to their sexually active children. Scope of knowledge of modes of transmission and means of prevention of HIV/AIDS is still worrying. This study identified the presence of major misconceptions pertaining condom use. CBOs showed an encouraging commitment in participating in the HIV/AIDS prevention activities. They also have showed a sense of program ownership and believed that they can serve as a link between the policy makers and the community. Parents and community members are aware of their potentials contributions and are willing to actively participate in HIV/AIDS prevention and control activities. Therefore, parents and communities have to be given a chance to participate in HIV/AIDS prevention and control activities as they are at the front in bearing its burden. Key words: family ,CBOs and HIV/AIDS prevention
Giant lobes of Centaurus A as seen in radio and gamma-ray images obtained with the Fermi-LAT and Planck satellites

description: The γ-ray data of Fermi-LAT on the giant lobes of Centaurus A are analysed together with the high frequency radio data obtained with the Planck satellite. The large γ-ray photon statistics, accumulated during seven years of observations, and the recently updated Fermi collaboration software tools allow substantial extension of the detected γ-ray emission towards higher energy, up to 30 GeV, and lower energy, down to 60 MeV. Moreover, the new γ-ray data allow us to explore the spatial features of γ-ray emission of the lobes. For the north lobe, we confirm, with higher statistical significance, our earlier finding on the extension of γ-ray emission beyond the radio image. Moreover, the new analysis reveals significant spatial variation of γ-ray spectra from both lobes. On the other hand, the Planck observations at microwave frequencies contain important information on spectra of synchrotron emission in the cutoff region, and thus allow model-independent derivation of the strength of the magnetic field and the distribution of relativistic electrons based on the combined γ-ray and radio data. The interpretation of multiwavelength spectral energy distributions (SEDs) of the lobes within a pure leptonic model requires strong enhancement of the magnetic field at the edge of the south lobe. Alternatively, a more complex, leptonic-hadronic model of the γ-ray emission, postulating a non-negligible contribution of the π^0 -decay component at highest energies, can explain the γ-ray data with a rather homogeneous distribution of the magnetic field over the giant lobes.

In these formalisms, the velocity field of a perfect fluid is described by scalar potentials. With this we can obtain the evolution equations of the fluid and its Hamiltonian. In the scenario of quantum cosmology the Schutz's formalism makes it possible to introduce phenomenologically a time variable in minisuperspace models.

Αυτά τα βίντεο είναι κατασκευασμένα (synthetic media) έτσι ώστε τα πρόσωπα τα οποία απεικονίζονται στο αυθεντικό βίντεο να αντικαθίστανται από ένα άλλο πρόσωπο με τη χρήση της Τεχνητής Νοημοσύνης. Στην πραγματικότητα, στα Deepfake βίντεο βλέπουμε ένα άτομο –διάσημο ή μη– να κάνει ή να λέει κάτι που ποτέ δεν έκανε ή είπε. Μέχρι πρόσφατα, η τεχνολογία των ψεύτικων βίντεο περιοριζόταν κυρίως στην ανάπτυξη της Τεχνητής Νοημοσύνης. Ωστόσο, το 2017 ένας χρήστης του "Reddit" γνωστός με το όνομα "Deepfakes" ανέπτυξε την ίδια τεχνολογία με τη βοήθεια της δωρεάν πλατφόρμας μηχανικής μάθησης ανοιχτού κώδικα της ομάδας "Google Brain" που ονομάζεται "Tensor Flow". Χρησιμοποίησε τη δημιουργία του για να βάλει πρόσωπα διασημοτήτων (ηθοποιούς, μουσικούς κ.α.) στα σώματα πορνοστάρ. Πολλά μέσα ενημέρωσης ανέφεραν αυτές τις ψεύτικες πορνογραφικές ταινίες, στις οποίες έδωσαν το όνομα "Deepfakes". Στην παρούσα διπλωματική εργασία θα αναλυθεί η τεχνολογία των Deepfakes, αλλά θα δοθούν και ορισμοί. Πως ξεκίνησαν τα Deepfakes; Τι σχέση έχουν με τα fake news; Πως εξελίσσεται η τεχνολογία αυτών; Πόσο επηρεάζει το κοινό; Επίσης, θα γίνει και μια ποσοτική έρευνα σχετικά με το θέμα.
description: Deepfakes have been very popular on the internet in recent years, but many people don't realize they exist. As a result, they think they're seeing the real thing. Since these videos belong to synthetic media, the original faces have been replaced with artificially intelligent technology. In Deepfake videos, we see a person - famous or not - doing or saying something they never did or said. The development of artificial intelligence has largely been responsible for the technology of fake videos until recently. The same technology was developed by a Reddit user, known as "Deepfakes" in 2017, using "Google Brain's" free open source tool called "TensorFlow". His creation allowed him to put celebrity faces (actors, musicians, etc.) on the bodies of pornstars. Most of the mass media reported on these fake pornographic films, which they called "Deepfakes". An analysis of Deepfakes Technology and definitions are provided in this study. When did Deepfakes begin? How does fake news relate to Deepfakes? How are they evolving? What is the impact of the audience? Quantitative research will also be conducted.

description: Sneutrino inflation employs the fermionic partners of the inflaton and stabilizer field as right-handed neutrinos to realize the seesaw mechanism for light neutrino masses. We show that one can improve the latest version of this scenario and its consistency with the Planck data by embedding it in the theory of cosmological $α$-attractors.

description: The present paper presents the results of multilingual and intercultural activities, which were implemented in plurilingual students aged 9-10 and 11-12 years in specific primary schools of Edessa and Giannitsa. Specifically, a qualitative research was conducted based on semi-structured interview with ten primary school students. In the present paper we try to investigate whether the awakening of primary school students in languages and cultures through courses or activities can introduce them to the concepts of “Multilingualism and Interculturalism” and lead them to the development of multilingual and intercultural skills. On account of this, the research was based on the combined implementation of Pluralistic Approaches (Awakening to Languages, Intercultural Approach and Mutual Understanding of Related Languages) for the design and implementation of activities. This research project was implemented during the school year 2022 with a duration of 2 hours for each age group.

description: This study, a cross-sectional census survey with a case control analysis, assesses various determinants of functionality of District Health Management Teams (DHMTs) in Addis Ababa. The questionnaire survey component was carried out among 16 DHMTs from December, 1992 to February, 1993. The objectives of the study were to describe the work of the various health teams and classify them as functional ir nonfunctional. The findings revealed that eight of the DHMTs were performing 60% or more of the activities mentioned in their job description, this being the cut-off point for determining functionality. The criterion for functionality was then further strengthened, limiting functionality to those teams who performed 64% of their required activities, leaving seven in this category. comparing these with the five nonfunctional teams (~ 56% of their required activities) various associations between structural team characteristics and internal team interaction processes were found. DHMT functionality was positively associated with the academic qualifications of the team leader (OR=14.1 with 95% CI 14-259), with the presence of job descriptions for the team members (OR=4.0 with 95% CI 3.8-57.3), with the size of the team (OR=10 with 95% CI 9.98-128.82), and with the presence of research activities (OR=5 with 95% CI 4.1-106.4).

description: We consider the problem of collectively delivering some message from a specified source to a designated target location in a graph, using multiple mobile agents. Each agent has a limited energy which constrains the distance it can move. Hence multiple agents need to collaborate to move the message, each agent handing over the message to the next agent to carry it forward. Given the positions of the agents in the graph and their respective budgets, the problem of finding a feasible movement schedule for the agents can be challenging. We consider two variants of the problem: in non-returning delivery, the agents can stop anywhere; whereas in returning delivery, each agent needs to return to its starting location, a variant which has not been studied before. We first provide a polynomial-time algorithm for returning delivery on trees, which is in contrast to the known (weak) NP-hardness of the non-returning version. In addition, we give resource-augmented algorithms for returning delivery in general graphs. Finally, we give tight lower bounds on the required resource augmentation for both variants of the problem. In this sense, our results close the gap left by previous research.

description: To accommodate the recently observed non-zero reactor mixing angle $θ_{13}$, we consider the lepton mixing matrix as Tri-bimaximal mixing (TBM) form in the leading order along with a perturbation in neutrino sector. The perturbation is taken to be a rotation in 23 plane followed by a rotation in 13 plane, i.e., $R_{23}(θ_{23}')R_{13}(θ_{13}',ϕ)$. We obtain the allowed values of the parameters $θ_{23}'$, $θ_{13}'$ and $ϕ$, which can accommodate all the observed mixing angles consistently and calculate the phenomenological observables such as the Dirac CP violating phase ($δ_{CP}$), Jarlskog invariant ($J_{CP}$), effective majorana mass $M_{ee}^ν$, and $m_{ν_e}$, the electron neutrino mass. We find that $δ_{CP}$ can take any values between $0$ and $-π/2$ and $M_{ee}^ν$ always comes below its experimental upper limit.

description: Der Umgang mit verschiedenen Darstellungsformen im Bereich funktionaler Zusammenhänge und der Wechsel zwischen diesen werden als mathematische Schlüsselfähigkeit angesehen. Dennoch zeigen Schülerinnen und Schüler vielfältige Schwierigkeiten in diesem Bereich (Bossé, Adu-Gyamfi & Cheetham, 2011). Aus diesem Grund besteht das Ziel des Projekts CODI (COnceptual DIfficulties in the field of functional relationships) darin, ein Diagnoseinstrument zum Aufdecken von Lernschwierigkeiten der Schülerinnen und Schüler in den Jahrgangsstufen 9 und 10 im Kompetenzbereich der Darstellung funktionaler Zusammenhänge zu entwickeln. Das Diagnoseinstrument soll im Unterricht flexibel einsetzbar sein und die Lehrkräfte bei der individuellen Diagnose und Förderung im Bereich typischer Lernschwierigkeiten unterstützen. In Anlehnung an die Ergebnisse des Projekts HEUREKO (vgl. Nitsch et al., 2014) werden zur Strukturierung des Inhaltsbereichs verschiedene Darstellungswechsel unterschieden: Der Wechsel zwischen Graph und situativer Beschreibung (GS), der Wechsel zwischen situativer Beschreibung und Gleichung (SA) und der Wechsel zwischen Graph und Gleichung (GA).

description: We examine the pair entanglement in the ground state of finite dimerized spin-$s$ chains interacting through anisotropic $XY$ couplings immersed in a transverse magnetic field, by means of a self-consistent pair mean field approximation. The approach, which makes no a priori assumptions on the pair states, predicts, for sufficiently low coupling between pairs, $2s$ distinct dimerized phases for increasing fields below the pair factorizing field, separated by spin parity breaking phases. The dimerized phases lead to approximate magnetization and pair entanglement plateaus, while the parity breaking phases are characterized by weak pair entanglement but non-negligible entanglement of the pair with the rest of the system. These predictions are confirmed by the exact results obtained in finite $s=1$ and $s=3/2$ chains. It is also shown that for increasing values of the spin $s$, the entanglement of an isolated pair, as measured by the negativity, rapidly saturates in the anisotropic $XY$ case but increases as $s^{1/2}$ in the $XX$ case, reflecting a distinct single spin entanglement spectrum.

description: We expect that many-core microprocessors will push performance per chip from the 10 gigaflop to the 10 teraflop range in the coming decade. To support this increased performance, memory and inter-core bandwidths will also have to scale by orders of magnitude. Pin limitations, the energy cost of electrical signaling, and the non-scalability of chip-length global wires are significant bandwidth impediments. Recent developments in silicon nanophotonic technology have the potential to meet these off- and on- stack bandwidth requirements at acceptable power levels. Corona is a 3D many-core architecture that uses nanophotonic communication for both inter-core communication and off-stack communication to memory or I/O devices. Its peak floating-point performance is 10 teraflops. Dense wavelength division multiplexed optically connected memory modules provide 10 terabyte per second memory bandwidth. A photonic crossbar fully interconnects its 256 low-power multithreaded cores at 20 terabyte per second bandwidth. We have simulated a 1024 thread Corona system running synthetic benchmarks and scaled versions of the SPLASH-2 benchmark suite. We believe that in comparison with an electrically-connected many-core alternative that uses the same on-stack interconnect power, Corona can provide 2 to 6 times more performance on many memory-intensive workloads, while simultaneously reducing power.
