description: Αντικείμενο της παρούσας διπλωματικής εργασίας αποτέλεσε η διερεύνηση ανάπτυξης δεξιοτήτων του 21ου αιώνα σε μαθητές/τριες της Πρωτοβάθμιας Εκπαίδευσης, όταν ενεπλάκησαν σε δραστηριότητες Εκπαιδευτικής Ρομποτικής. Πιο συγκεκριμένα, μελετήθηκε η αξιοποίηση του πακέτου Εκπαιδευτικής Ρομποτικής LEGO® Education WeDo 2.0 Core Set και ο τρόπος που μπορεί να συμβάλει στην καλλιέργεια της δημιουργικότητας των μαθητών/τριών. Κατά τη διάρκεια της έρευνας, υλοποιήθηκαν σε Δημοτικό Σχολείο διδακτικές παρεμβάσεις STEAM. Οι μαθητές/τριες συμμετείχαν σε αυτές και μέσα από την ενεργό εμπλοκή τους, δημιούργησαν διάφορες και πρωτότυπες κατασκευές με το πακέτο Εκπαιδευτικής Ρομποτικής LEGO® Education WeDo 2.0 Core Set. Η διαδικασία της κατασκευής των προϊόντων έλαβε χώρα εντός του σχολικού ωραρίου, σε περιβάλλον πραγματικής τάξης, στα πλαίσια του Αναλυτικού Προγράμματος Σπουδών της Πρωτοβάθμιας Εκπαίδευσης. Έπειτα, συγκροτήθηκε μία ομάδα κριτών οι οποίοι κλήθηκαν να αξιολογήσουν σε απομόνωση τα προϊόντα των μαθητών/τριών ως προς τη δημιουργικότητα, συγκρίνοντάς τα μεταξύ τους. Κατά την αξιολόγηση της δημιουργικότητας των προϊόντων χρησιμοποιήθηκε η Τεχνική της Συναινετικής Αξιολόγησης (Consensual Assessment Technique – CAT) που ανέπτυξε η Teresa Amabile (1982; 1983; 1996) προκειμένου να διερευνηθεί η επίδραση στην ανάπτυξη της δημιουργικότητας των μαθητών/τριών κατά την ενσωμάτωση του πακέτου Εκπαιδευτικής Ρομποτικής LEGO® Education WeDo 2.0 Core Set στην εκπαιδευτική διαδικασία.
description: The subject of this thesis was the investigation of the development of the 21st century skills in the students of Primary School, when they were involved in Educational Robotics activities. More specifically, the utilization of the LEGO® Education WeDo 2.0 Core Set Educational Robotics kit and the way it can contribute to the cultivation of the creativity of students was examined. During the research, STEAM interventions were implemented in Primary School. Students participated in them and through their active involvement, they created various and original constructions with the LEGO® Education WeDo 2.0 Core Set Educational Robotics kit. The process of manufacturing the products took place during school hours, in a real classroom environment, within the Curriculum of Primary Education. A group of judges was then set up to assess in isolation the students’ products in terms of creativity, comparing them to each other. The Consensual Assessment Technique (CAT) developed by Teresa Amabile (1982; 1983; 1996) was used in evaluating the creativity of the products in order to explore the impact on the development of students’ creativity when integrating the LEGO® Education WeDo 2.0 Core Set Educational Robotics kit into the educational process.

description: Η υποστήριξη της κατηγορίας είναι το μέσο του θύματος για να συμμετέχει στην ποινική διαδικασία. Ο σκοπός της παρούσας διπλωματικής εργασίας είναι να αναλύσει τις διατάξεις του νέου Κώδικα Ποινικής Δικονομίας που ορίζει τις ουσιαστικές προϋποθέσεις για τη συμμετοχή του θύματος στην προδικασία και τη δίκη. Επίσης, αναλύονται οι συνέπειες που προκαλούνται και τα δικαιώματα που έχει το θύμα, μετά τη νόμιμη δήλωση για συμμετοχή στην ποινική διαδικασία. Ολοκληρώνοντας αυτή τη διπλωματική εργασία, παρόλο που η συμμετοχή του θύματος στη δίκη προκάλεσε θεωρητικές και νομολογιακές συγκρούσεις, αυτά τα δικονομικά ζητήματα επιλύθηκαν, όπως παρουσιάζονται σε αυτή τη διπλωματική εργασία.
description: The support of the accusation is the victim’s way to participate in the criminal proceedings. The aim of the present thesis is to analyze the articles of the new Criminal Procedure Code that defines the essential conditions for the victim’s involvement in the pretrial and trial. Furthermore, are analyzed the consequences that are caused and the rights that the victim has, after his legal statement for participating in the criminal proceedings. Concluding this thesis, although the fact that the victim’s involvement in the trial has raised theoretical and judicial conflicts, these judicial issues are solved, as presented at this thesis.

description: We give a bird's-eye view of the plastic deformation of crystals aimed at the statistical physics community, and a broad introduction into the statistical theories of forced rigid systems aimed at the plasticity community. Memory effects in magnets, spin glasses, charge density waves, and dilute colloidal suspensions are discussed in relation to the onset of plastic yielding in crystals. Dislocation avalanches and complex dislocation tangles are discussed via a brief introduction to the renormalization group and scaling. Analogies to emergent scale invariance in fracture, jamming, coarsening, and a variety of depinning transitions are explored. Dislocation dynamics in crystals challenges non equilibrium statistical physics. Statistical physics provides both cautionary tales of subtle memory effects in nonequilibrium systems, and systematic tools designed to address complex scale-invariant behavior on multiple length and time scales.

description: In the first part of this thesis we establish dimension bounds for spaces of polynomial growth solutions to divergence form parabolic partial differential equations with time-dependent coefficients as well as sharp bounds in the case of time-independent coefficients. The second, main part of this thesis is devoted to smooth, harmonic maps of low index, in particular to the classification of such maps into round spheres. Towards this we first study the change of the index of smooth, harmonic submersions into round spheres upon consideration as maps into higher-dimensional round spheres, that is after composition with the totally geodesic inclusion map into a higher-dimensional sphere. This is illustrated by the examples of the Hopf maps $S^3\rightarrow\,S^2$ and $S^1\rightarrow\,S^1$. As an application we can describe for $n\geq3$ a class of harmonic morphisms of low index from the round $n$-sphere into submanifolds of the round $n$-sphere arising from smooth maps of constant rank. Finally we prove an El Soufi-type index bound for smooth, harmonic maps from simply connected Riemannian manifolds satisfying the Killing property into round spheres. This bound depends only on the domain manifold, in particular it does not depend on the dimension of the codomain sphere. Focussing thereafter on the case that the codomain is the round two-sphere, we can show that every smooth, harmonic map of low index with respect to this new index bound must be a harmonic morphism.

Ειδικότερα, επιχειρείται μια προσπάθεια ανάλυσης διαφόρων ψηφιακών εργαλείων και εφαρμογών προς την ανάπτυξη των γλωσσικών δεξιοτήτων της κατανόησης και της παραγωγής προφορικού λόγου, της προφορικής διάδρασης και της διαμεσολάβησης. Είναι κοινός τόπος το γεγονός ότι στον εικοστό πρώτο αιώνα, στην εποχή του ψηφιακού, αποτελεί επιτακτική ανάγκη η ένταξη και η χρήση αντιστοίχων εργαλείων στην εκπαιδευτική διαδικασία αποβλέποντας στην ανάπτυξη της αυτονόμησης της μάθησης και στην κινητροδότηση των μαθητών και μαθητριών προκειμένου να αναπτύξουν - πέραν από τις εν λόγω γλωσσικές δεξιότητες - γενικές δεξιότητες και ικανότητες που θα αποτελούν εφόδια σε όλη τους τη ζωή. Για το λόγο αυτό, κρίνεται απαραίτητη η επιλογή των κατάλληλων εργαλείων που θα μπορούν να παρέχουν άμεση τροφοδότηση στο μέτρο που αυτό καθίσταται δυνατόν. Κύριο μέλημα αυτής της εργασίας, επομένως, συνιστά η διερεύνηση μιας σειράς εφαρμογών ως προς μια σειρά κριτηρίων. Στο πλαίσιο αυτής, θα αξιολογηθούν εμπειρικά με μια σχάρα αξιολόγησης ως προς τις δυνατότητες και τα οφέλη τους προς την ανάπτυξη του προφορικού λόγου.
description: This paper seeks to highlight the importance and necessity of using digital technologies in language teaching. In particular, an effort is being made to integrate and analyze various digital tools and applications towards the development of language skills of oral comprehension, speaking, oral interaction and mediation. It is common ground that in the twenty-first century, in the digital age, it is imperative to integrate and use relevant tools in the educational process with a view to developing the autonomy of learning and to motivating students and students to develop - in addition to these language skills - general skills and competences that will be relevant throughout their lives. It is therefore necessary to select the appropriate tools that can provide direct supply as far as possible. The main concern of this work therefore recommends exploring a number of applications in relation to a variety of criteria. In this context, they will be evaluated empirically with an evaluation grill as to their potential and benefits for the development of oral speech.

description: Η παρούσα εργασία εξετάζει τη σχέση ανάμεσα στην πολιτική και καλλιτεχνική δράση θέτοντας ως βασικό συνδετικό νήμα την έννοια-δυνατότητα της ανα-δημιουργίας. Η εργασία διαιρείται σε δύο μέρη. Το πρώτο, πραγματεύεται τις προϋποθέσεις της δημιουργίας και επικεντρώνεται στην πολιτική θεωρία του Κορνήλιου Καστοριάδη: τις θέσεις του για το έργο τέχνης σε αντιστοιχία με τη νέα δημιουργία και το πρόταγμα της αυτονομίας, την αποκαλυπτική και κριτική λειτουργία της τέχνης και την πρόσληψη του καλλιτέχνη ως πολιτικού υποκειμένου δράσης. Στο δεύτερο μέρος, η εστίαση είναι στη Χάνα Άρεντ και συγκεκριμένα στην αισθητική διάσταση της δημόσιας σφαίρας, η οποία καθιστά δυνατή την πρόσληψη της καλλιτεχνικής δράσης ως μια πολιτική πρακτική ανασχηματισμού. Ο σχεσιακός χαρακτήρας του πολιτικού στην Άρεντ και στον Καστοριάδη ενδυναμώνει το βασικό μας επιχείρημα σχετικά με τη σύνδεση ανάμεσα στην τέχνη (πιο συγκεκριμένα τη σύγχρονη τέχνη) και την πολιτική, την οποία εντοπίζουμε σε παραδείγματα που έχουμε επιλέξει (Λορ Προυβόστ, Ερνέστο Νέτο, Μαρία Χασάμπη, Βίβιαν Μάιερ, Κρίστο και Ζαν-Κλοντ, Μαρίνα Αμπράμοβιτς, Κρίστιαν Μάρκλεϊ, Μπρους Νάουμαν, Σαντιάγκο Σιέρα). Τέλος, η κριτική της Κλερ Μπίσοπ στη σχεσιακή αισθητική του Νικολά Μπουριό και η ενεργοποίηση της θεωρίας του αγωνιστικού πλουραλισμού της Σαντάλ Μουφ, αναδεικνύουν την πολιτική σημασία της συγκρουσιακής συναίνεσης προς αντίθεση της συναίνεσης που προτείνει η Άρεντ.
description: This paper examines the relation between the political and the artistic action having as a connecting link the concept-possibility of re-creation. The paper is divided in two parts. Τhe first one, discusses the conditions of creation and focuses on the political theory of Cornelius Castoriadis: his positions on the work of art in correspondence with the new creation and the project of autonomy, the revelatory and critical function of art and the socio-political role of the artist as a subject of action. In the second part, the focal point is on Hannah Arendt and the aesthetic dimension of the public sphere, which encourages the approach of the artistic action as a political practice of transformation. The relational character of the political in Arendt and Castoriadis strengthens our major argument regarding the connection between (contemporary) art and politics, which is supported with examples (Laure Prouvost, Ernesto Neto, Maria Hassabi, Vivian Meier, Christo και Jeanne-Claude, Marina Abramovic, Christian Marclay, Bruce Nauman, Santiago Sierra). Claire Bishop's critique on Nicholas Bourriaud’s relational aesthetics and the activation of Chantal Mouffe’s theory on competitive pluralism complements the dimension of dissensus as a response to Arendt's proposed consensus.
Adaptive optical equalization for optical communication systems

description: Optical fiber communication systems have the advantages of long-distance transmission and large information capacity over traditional communication systems using copper cables. The signal processing can be performed in the electronic domain and/or the optical domain. As chromatic dispersion is one of the main transmission impairments, the aim of this research is to explore and develop optical signal processing for adaptive equalization, by replacing part of digital signal processing with optical signal processing. This thesis explores the self-calibration of a reconfigurable photonic integrated circuit (PIC) filter and the implementation of PIC as optical equalizers in an optical fiber communication system to compensate chromatic dispersion.
Knowledge, Attitude, Risk Behavior on HIV/Aids And Willingness to Participate in an HIV Vaccine Trial among High School Teachers in Addis Ababa City, Ethiopia

description: There is an ongoing study on sexual behavior in Akaki factory workers and many KABP studies. A cross-sectional study on high risk behavior and knowledge on vaccines and their willingness to participate in HIV vaccine trial among randomly selected high school teachers was conducted from January 10 to 30, 2002 in Addis Ababa city. Mean age at first marriage for high school teachers was 26.7 years. Of the 621 high school teachers (26.4%) had engaged in commercial sex and 249 (40.1%) had non-regular noncommercial sexual contacts in the last 12 months prior to the survey. Mean age at first sexual intercourse was 18.7 years. Ever use of condoms by the high school teachers was 65.1%. Knowledge on HIV prevention was very low. However, knowledge on vaccines and their willingness to participate in HIV vaccine trial was very high and modestly high, respectively. Although it is recognized that the specific educational needs will vary in different contexts, our data support the need for incorporate vaccine trial's education into the design and implementation of future HIV vaccine trials. Serial surveillance surveys are necessary to see the trend of change in behavior of the study population. HIV preventive messages should be repeatedly directed to high school teachers. There is a need to increase HIV awareness in high school teachers.

description: This thesis aims to examine the necessity of founding the University of Thessaloniki and to critically evaluate its role and function in the general socio-political context in the interwar period, through the press of the time. The research focused on the reasons for its establishment, the stake of immediate or gradual integration, the problems of the classical or practical orientation, the disputes and rifts that arose and concerned its staffing by progressive teachers, as well as the struggles of the student movement. For the aim of the research, articles from newspapers in Thessaloniki and Athens were studied. The research findings conclude that the press, influenced by the general political climate of the interwar period and depending on the political positions embraced by the owners, directors and editors of the newspapers, aimed at serving individual or collective interests.

Assessment of Reproductive Health Behavior and Needs of Street Youth in Dessie Town, Amhara Region
Creators: name: Yimam, Ejigayehu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Background: Street youth are exposed to situations that make them vulnerable to sexual and reproductive health problems. The majority of street children are living in conditions of severe deprivation, which place them at all kinds of health risks. Street youth have risky sexual behaviors that increase the likelihood of adverse sexual and reproductive health consequences. Objectives and methods: A cross sectional survey was conducted among 343 street youth with focus group discussions to assess reproductive health behavior and needs of street youth in Dessie Town. The total number of street youth in the town was determined to be 1900 after conducting census for two days. The study subjects were identified by using systematic sampling from the sampling frame. Data was collected using structured questionnaire, entered and analyzed using EPI info and SPSS statistical program respectively. Results: Majority, 67.9%, of the respondents had started sexual intercourse with the mean age of 15.2 years. Ever having sex was associated with being male, income of 5-10 birr and greater than 10 birr per day, more than one year on the street, former residence being rural areas, alcohol drinking and khat chewing. 80.6% of the respondents have more than one sexual partners and the mean lifetime number of sexual partners was 4.85. Among sexually active street youth, 63.9 % had ever used modern contraceptives and it was associated with type of street life, sex, marital status, secondary education and alcohol drinking. Consistent use of condoms was found to be low, 22.8%. Living with peers and alone, former residence being rural areas, more than one year on the street and number of sexual partners above one were found to be associated with consistent use of condoms. It is important to mention that the level of awareness about contraception, HIV/AIDS and other STIs was considerably high; nevertheless, most of them are found to be involved in risky sexual behaviors and the great majority of them considered themselves at low risk for HIV. Conclusion: It was concluded that despite the majority of street youth had adequate knowledge of selected reproductive health issues, most street youth engage in high risk sexual practices. This fact calls for a coordinated and comprehensive effort by responsible organizations to mobilize peer based interventions to bring behavioral change in reducing risky sexual practices.

description: We argue that the degrees of freedom in a d-dimensional CFT can be re-organized in an insightful way by studying observables on the moduli space of causal diamonds (or equivalently, the space of pairs of timelike separated points). This 2d-dimensional space naturally captures some of the fundamental nonlocality and causal structure inherent in the entanglement of CFT states. For any primary CFT operator, we construct an observable on this space, which is defined by smearing the associated one-point function over causal diamonds. Known examples of such quantities are the entanglement entropy of vacuum excitations and its higher spin generalizations. We show that in holographic CFTs, these observables are given by suitably defined integrals of dual bulk fields over the corresponding Ryu-Takayanagi minimal surfaces. Furthermore, we explain connections to the operator product expansion and the first law of entanglement entropy from this unifying point of view. We demonstrate that for small perturbations of the vacuum, our observables obey linear two-derivative equations of motion on the space of causal diamonds. In two dimensions, the latter is given by a product of two copies of a two-dimensional de Sitter space. For a class of universal states, we show that the entanglement entropy and its spin-three generalization obey nonlinear equations of motion with local interactions on this moduli space, which can be identified with Liouville and Toda equations, respectively. This suggests the possibility of extending the definition of our new observables beyond the linear level more generally and in such a way that they give rise to new dynamically interacting theories on the moduli space of causal diamonds. Various challenges one has to face in order to implement this idea are discussed.

description: We aim at studying the asymptotic properties of typical positive braids, respectively positive dual braids. Denoting by $μ_k$ the uniform distribution on positive (dual) braids of length $k$, we prove that the sequence $(μ_k)_k$ converges to a unique probability measure $μ_{\infty}$ on infinite positive (dual) braids. The key point is that the limiting measure $μ_{\infty}$ has a Markovian structure which can be described explicitly using the combinatorial properties of braids encapsulated in the Möbius polynomial. As a by-product, we settle a conjecture by Gebhardt and Tawn (J. Algebra, 2014) on the shape of the Garside normal form of large uniform braids.

title: Microfluidic systems based on electroactive polymers technology

description: Dielectric elastomer actuators (DEAs) have been widely investigated for more than 30 years. Lately, several fabrication methods have successfully allowed the creation of very thin elastomer and electrode layers. The development of attractive applications, in which DEAs offer advantages over conventional technologies, is thus necessary for the advance of the technology. In this work, new biocompatible microfluidic devices based on DEAs are developed. In the first part of this thesis, several prototypes of peristaltic pumps of single layer dielectric elastomer actuators are designed, manufactured and characterized. Although these prototypes were not able to produce fluid flow, novel insights into the capabilities of Electroactive Polymer technology were gained. In the second part of this work, a pumping micromixer as a novel application of dielectric elastomer stacked actuators is manufactured. The pumping micromixer is based on peristaltic movements, which gently act as a mixer and a pump for microfluidics. Experimental data show a maximal flow rate of 21.5 µL/min at 10 Hz. Image analysis at the outlet proves a 50/50 mixing when all actuators are functioning at the same pace and voltage. The performance of the pumping micromixer is further studied with the Finite Element Method, using the COMSOL Multiphysics® software. Simulations demonstrate the versatility of the pumping characteristics of such a microdevice, from very few µL/min to mL/min, and from a very low pressure in the range of Pa to hundreds of kPa, by only changing the duty cycle, phase shift and actuation frequency.

description: Background: the global population estimated to be increased by 2.5 billion over the next 43 years, from the current 6.7 billion to 9.2 billion in 2050[1] . And Young people aged between 15 and 24 years make up1.2 billion of the world's population [26]. Also Ethiopia is at rapid population growth, of 2.6% per year. Adolescents and young adults may experience undesirable health consequences from early unprotected sexual activity, such as unintended pregnancy, unsafe abortion, sexually transmitted infections (STIs), including HIV, and pregnancy-related mortality and morbidity. [4] Objective of the study: To Asses modern contraceptive use and associated factors among undergraduate students. Methods: Across-sectional institution based study design to assess modern contraceptive use and associated factors among regular undergraduate students in Wachemo University during the 2009 E.C.From A total of 11742 students 383 students are participated in the study using stratified random sampling method. A self-administered pre-tested questionnaire was used to collect the data and data analysis was performed using statistical package for social science version 16.0 and Epi-info version 3.5.3 .Descriptive statistics were used to summarize the data An odds ratio of 95% confidence interval for factors associated with modern contraceptive use was computed using multiple logistic regression models. A p-value of ≤ 0.05 was considered as statistically significant. Result: The overall utilization of modern contraceptive in this study was 62.6% oral contraceptive pills 65.7%, followed by condom 17.6% condom and injectable 16.5%.being in age group 20-24Year [AOR 9.347(9.509, 19.377)], discussion with friends [AOR 4.099(2.010, 8.359)], exposure for contraceptive method messages [AOR 3.753(1.848,7.618)], having boy/girlfriend [AOR 2.138(1.042, 4.387)] showed significant positive association with modern contraceptive use. Conclusion and Recommendation: More than a third of the respondents have history of sexual activity among which only 62.6% were ever using contraceptive method. Health providers particularly working in university clinic should give detail information about the contraceptive methods; possible side effects because respondents in this study mentioned them as reason for not intended to use contraceptive method in the future. The government and NGO`s should work on the area of disseminating reproductive health information by Establishing and promoting sexual and reproductive clubs at schools in order to increase awareness and knowledge on contraceptive methods and enhance discussion with friends which has positive impact on contraceptive use. Further studies with both qualitative and quantitative method of data collection are recommended for researchers.

description: We develop a non-linear semi-parametric Gaussian process model to estimate periods of Miras with sparsely-sampled light curves. The model uses a sinusoidal basis for the periodic variation and a Gaussian process for the stochastic changes. We use maximum likelihood to estimate the period and the parameters of the Gaussian process, while integrating out the effects of other nuisance parameters in the model with respect to a suitable prior distribution obtained from earlier studies. Since the likelihood is highly multimodal for period, we implement a hybrid method that applies the quasi-Newton algorithm for Gaussian process parameters and search the period/frequency parameter over a dense grid. A large-scale, high-fidelity simulation is conducted to mimic the sampling quality of Mira light curves obtained by the M33 Synoptic Stellar Survey. The simulated data set is publicly available and can serve as a testbed for future evaluation of different period estimation methods. The semi-parametric model outperforms an existing algorithm on this simulated test data set as measured by period recovery rate and quality of the resulting Period-Luminosity relations.

description: Introduction: Sexual risk behavior accounts for a large number of vulnerabilities for acquiring HIV infection. Alcohol use has been shown to increase high-risk sexual behavior. Moreover, the social dynamics that surround alcohol use, sexual risk behavior and HIV infection and interactions between these issues warrant a search for alternative ways of dealing with the problem. Worldwide Human Immunodeficiency Virus poses an enormous challenge on the survival of humankind, and most serious infectious disease challenges to public health. Risk sexual behaviors among adolescents and young adults have received growing attention during the past decade. Worldwide, 2.6 million adolescents are newly infected every year, with sexual transmission being the most common way the human immunodeficiency virus is contracted by adolescents. Objectives: To assess sexual risk behaviors, among preparatory and vocational students in Bishoftu city administration, Oromia Regional. Methods: Across sectional study was conducted from January to Jun, 2011 among preparatory and vocational students. Two stage sampling technique was used to select sample size of 924 students from both schools. Data were collected through anonymous structured questionnaire and pretested among other students who were not participating in the study. The questionnaire consists of socio-demographic characteristics, and sexual history of Preparatory and Vocational students. After data collection the data were cleaned, audited and entered into EPI info and analyzed using SPSS for windows computer software packages. A bivariate and logistic regression analysis was employed. Result: A total 875 students from Preparatory and Vocational schools completed the questionnaire making the response rate of 98%. Overall our study finding showed that 30.2% Preparatory and Vocational school students were to be at risk sexual behavior. Risk sexual behavior was positively associated with sex (being male) (AOR =1.47; 95 %; C I; 1.08, 2.02), age 18 years and above (AOR = 2.62; 95% C I; 1.79, 3.83), drink alcohol frequently (AOR=1.93; 95% C I; 1.38, 2.68) and smoke cigarette frequently (AOR=168; 95% C I; 1.12, 2.52). Conclusion and Recommendation: Considerable proportion of Preparatory and Vocational students were to be at risk of sexual behavior. This study also found that age 18 years and above, male sex, drink alcohol and smoking cigarette frequently was associated with risk sexual behavior. And more effective school health program intervention should be implemented among school youths to prevent risk sexual behavior through school based sex education. Intervention strategies among school youths should be implemented to prevent substance use (alcohol and cigarette) by the use of health- promoting school model charter of WHO.

description: Shape memory polymers (SMPs), comprising a distinctive shape memorizing capability, is a significant and evolving branch of smart polymers. Shape memory polymer composites (SMPCs) were developed by reinforcing the SMP matrix to improve the inherently weak mechanical properties and durability of SMPs. General polymer composites have become a successful substitute construction material. Similarly, with both the structural performance and shape memory effect (SME), SMPCs will be ideal candidates to remedy the challenges of futuristic construction techniques. Specifically, SMPCs can be used effectively in prefabricated modular constructions, curved beams and other civil infrastructures to overcome drawbacks associated with the high requirements of labour, time and cost. This research aimed to develop circular and square hollow sectioned (CHS and SHS) structural SMPC components for the construction industry. E-glass, carbon and natural basalt fibres were integrated as reinforcements. The thermomechanical, mechanical, shape memory and programming damage characteristics were evaluated to analyse material performance. The SMPC structural sections were fabricated with a specially designed mould and the SME, damage predictions, structural performance and proof of concept were analysed. The durability of SMPCs was also investigated; mainly in terms of behaviour under fire, smoke generation, thermal decomposition, volatile gas characterisation, fatigue, moisture and elevated temperatures. Importantly, this thesis presents a firsthand, indepth programming damage analysis framework to fill knowledge gaps in the SMPC research field by linking experimental outcomes with viscoelastic FEA studies. Overall, this study established a comprehensive and wellrounded SMPC design outline to develop SMPC structural sections for civil constructions for the first time. The outcomes of this thesis will guide engineers to revolutionize well established construction methods and technologies, and provide innovative solutions to make civil constructions smarter, faster and cheaper.

description: We analyse the evolution of cosmological perturbations which leads to the formation of large isolated voids in the Universe. We assume that initial perturbations are spherical and all components of the Universe (radiation, matter and dark energy) are continuous media with perfect fluid energy--momentum tensors, which interact only gravitationally. Equations of the evolution of perturbations for every component in the comoving to cosmological background reference frame are obtained from equations of energy and momentum conservation and Einstein's ones and are integrated numerically. Initial conditions are set at the early stage of evolution in the radiation-dominated epoch, when the scale of perturbation is much larger than the particle horizon. Results show how the profiles of density and velocity of matter and dark energy are formed and how they depend on parameters of dark energy and initial conditions. In particular, it is shown that final matter density and velocity amplitudes change within range $\sim$4-7\% when the value of equation-of-state parameter of dark energy $w$ vary in the range from --0.8 to --1.2, and change within $\sim$1\% only when the value of effective sound speed of dark energy vary over all allowable range of its values.

description: Οι ΤΠΕ συμβάλλουν σημαντικά στη βιώσιμη διαχείριση και χρήση γεωργικών και φυσικών πόρων. Στόχος της παρούσας εργασίας ήταν να διερευνηθούν οι δυνατότητες ανάπτυξης με τις ΤΠΕ με την κατάταξη των αντίστοιχων ιστοσελίδων. Για την αξιολόγηση των ιστοτόπων του εναλλακτικού τουρισμού της Ηπείρου χρησιμοποιήθηκαν 30 κριτήρια τεχνολογίας πληροφοριών και επικοινωνιών. Από την ανάλυση που πραγματοποιήσαμε φάνηκε πως τα sites και τα Portals που προβάλλουν τον εναλλακτικό τουρισμό στην Ήπειρο είναι ελλιπή και δεν πληρούν τα βασικά χαρακτηριστικά, ώστε να προσελκύουν επισκέπτες και να αναδείξουν τις δράσεις εναλλακτικού τουρισμού στην περιοχή. Προτάθηκε, λοιπόν, ένα σχέδιο για τη δημιουργία ενός ολοκληρωμένου portal, το οποίο θα περιέχει πληροφορίες για διαμονή, δραστηριότητες εναλλακτικού τουρισμού, φαγητό κλπ και θα καλύπτει βασικά χαρακτηριστικά, όπως η ύπαρξη μηχανής αναζήτησης, φόρμας επικοινωνίας, λογαριασμού στα social media και συνεχής ενημέρωση για νέες δράσεις κ.ο.κ.
description: ICT contributes significantly to the sustainable management and use of agricultural and natural resources. The aim of this paper was to explore the possibilities of development with ICT by ranking the respective websites. 30 criteria of information and communication technology were used for the evaluation of the alternative tourism sites of Epirus. From the analysis we carried out it showed that the sites and Portals that promote alternative tourism in Epirus are incomplete and do not meet the basic characteristics, in order to attract visitors and highlight the alternative tourism activities in the area. Therefore, a plan was proposed for the creation of a complete portal, which will contain information about accommodation, alternative tourism activities, food, etc. and will cover key features, such as the existence of a search engine, contact form, social media account and continuous information about new actions and so on.
