description: Autonomous, agile quadrotor flight raises fundamental challenges for robotics research in terms of perception, planning, learning, and control. A versatile and standardized platform is needed to accelerate research and let practitioners focus on the core problems. To this end, we present Agilicious, a co-designed hardware and software framework tailored to autonomous, agile quadrotor flight. It is completely open-source and open-hardware and supports both model-based and neural-network--based controllers. Also, it provides high thrust-to-weight and torque-to-inertia ratios for agility, onboard vision sensors, GPU-accelerated compute hardware for real-time perception and neural-network inference, a real-time flight controller, and a versatile software stack. In contrast to existing frameworks, Agilicious offers a unique combination of flexible software stack and high-performance hardware. We compare Agilicious with prior works and demonstrate it on different agile tasks, using both model-based and neural-network--based controllers. Our demonstrators include trajectory tracking at up to 5g and 70 km/h in a motion-capture system, and vision-based acrobatic flight and obstacle avoidance in both structured and unstructured environments using solely onboard perception. Finally, we demonstrate its use for hardware-in-the-loop simulation in virtual-reality environments. Thanks to its versatility, we believe that Agilicious supports the next generation of scientific and industrial quadrotor research.

description: Σκοπός του παρόντος έργου είναι να διερευνηθούν οι δύο βασικοί πυλώνες της Γνωσιοθεωρίας του Ernst Cassirer, οι οποίοι αφορούν αφενός τη μέθοδο προσέγγισης της γνώσης και αφετέρου τη μορφοποίησή της. Ειδικότερα, η μέθοδος, την οποία εδώ κατονομάζουμε ως συναρτησιο-λειτουργική, αφορά μία προσπάθεια εδραίωσης μίας θεωρίας περί της διυποκειμενικής φύσης που η γνωστική ικανότητα του (κάθε) ανθρώπου ενέχει. Η φύση αυτή προκύπτει από την τάση του ανθρώπου να σχηματίζει και να αναγνωρίζει σχέσεις ανάμεσα σε επιμέρους αντικείμενα και μεταξύ αντικειμένων και του εαυτού του, και που αναδεικνύεται κυρίως μέσω του γεγονότος της αντικειμενικότητας των Μαθηματικών και της Φυσικής Επιστήμης. Όσον αφορά τη μορφοποίηση της γνώσης, η Φιλοσοφία των Συμβολικών Μορφών προτείνει ένα γνωστικό σύστημα το οποίο εδράζεται σε κάθε έκφανση του ανθρώπινου πολιτισμικού φαινομένου, επί τη βάσει του γεγονότος ότι ο Άνθρωπος οργανώνει τη γνώση του σε διάφορα επιμέρους συστηματοποιημένα σύνολα συμβόλων και συμβολισμών, είτε πιο πνευματικά, είτε πιο διανοητικά και εμπειρικά.
description: The purpose of this thesis is to study the two basic pillars of Ernst Cassirer’s Theory of Knowledge: the method of engaging Knowledge on the one hand, and its formation on the other. The method, that in this thesis we call functional, refers to an attempt of establishing a theory around the inter-subjective nature that is instilled in every person’s cognitive ability. This exact nature comes from the human tend to form and recognize relations between individual objects and herself, which is mainly manifested through the objectivity of Mathematics and Natural Science. As for the formation of knowledge, the Philosophy of the Symbolic Forms suggests a cognitive system that is founded on every aspect of the human civilizational phenomenon, on the basis that Human organizes her knowledge in different individual systematized sets of symbols and symbolisms, either spiritual, or more intellectual and empirical.

description: Acquired Immuno Deficiency Syndrome (AIDS) has become the current major public health problem in the developed and developing countries. The epidemic is one of the greatest challenges ever to Global well-being. This study was designed and conducted with the aim of assessing risky sexual behavior for HIV infection spreading with special focus on the night markets and mobile people. A multistage, cross-sectional survey and qualitative study was carried out between November 2003 and January 2004 in Gummer woreda, Gurage zone. A total of 838 respondents participated in the survey part and in the qualitative four FGDs of different key informants and 14 individual in-depth interviewees were enrolled and participated in this study. The result showed that 43 (19.2%) of males and 5 (1.8%) of females ever had extramarital sex .Females were being protective with [OR= 0.05, 95% CI: 0.01, 0.23]. Among the age group of 15-54years, 36 (18.2%) of 35-54 years and 25 (12.0%) of age 15-34 years had engaged in risky sexual behaviors in relationship to night markets. Regarding marital status, 50(10.0%) of married and 11 (3.3%) of not currently married had engaged in risky sexual in relationship to night markets. Among the married respondents, 26 (10. 8%) of males and one female had their first sexual contact with non-regular partners. Regarding occupation, 17 (6.6%) of farmers and 44 (7.6%) of others occupation (students, wives, traders and jobless) had engaged in risky sexual behaviors in relationship to night markets. Other occupation had 2.5 times more engaged in risky sexual behaviors than farmers with [OR= 2.5, 95%CI: 1.07, 5.90]. Among the respondents only 27 (3.2%) had reported frequently use of condom in the last six months during viii premarital and extramarital sex. Almost all, 826 (98.6%) have heard about HIV/AIDS. Eight hundred and twenty six (98.4%) reported that HIV/AIDS is transmitted by unprotected sex. Most of the FGDs discussants and individual in-depth interviewees said that nowadays night markets have become a source for HIV/AIDS transmission in the area. Most of the respondents did not think that they were at risk of acquiring HIV infection while they were at risk in relation ship to night markets and mobility. It needs urgent measure interms of HIV prevention and control in the study area.

description: We study entropy production (EP) in processes involving repeated quantum measurements of finite quantum systems. Adopting a dynamical system approach, we develop a thermodynamic formalism for the EP and study fine aspects of irreversibility related to the hypothesis testing of the arrow of time. Under a suitable chaoticity assumption, we establish a Large Deviation Principle and a Fluctuation Theorem for the EP.

Προέκταση αυτής της εργασίας μπορεί να γίνει με περαιτέρω ανάλυση των δομών αυτών. Συγκεκριμένα μπορεί να γίνει μελέτη των κλιμακούμενων δομών που μπορούν να προκύψουν πχ για δομές πέντε, έξι και λοιπά ζευγαριών βραχιόνων, ενώ στην περίπτωση του συντονιστή δίνονται περιθώρια για ανάπτυξη των σχέσεων και προσομοίωση τους.
description: In this paper, Mach Zehnder interferometer arrays of 3x3 and 4x4 structures were presented and simulated and situations of using these structures as switch, filter and demultiplexer elements were studied, while the programs created enable scaling to NxN structures. In particular, a program for NxN arrays was designed to solve the linear equations as derived from Lagali's work and their solutions were presented for three and four pairs of arm structures. In addition, a program was designed for both devices and its results were presented for the spectral imaging of filter and demultiplexer devices of various combinations of gaps in the arms. A mathematical solution of the optical field equations of an MZI 3x3 Dual Resonant MZI array was also performed by connecting two output arms to two input arms. Extension of this work can be done by further analysis of these structures. In particular, a study can be made of the scalar structures that can be obtained, e.g. for structures of five, six, etc. pairs of arms, while in the case of the coordinator, scope is given for developing the relationships and simulating them.

description: We investigate the general structure of mirror symmetry breaking in the Twin Higgs scenario. We show, using the IR effective theory, that a significant gain in fine tuning can be achieved if the symmetry is broken hardly. We emphasize that weakly coupled UV completions can naturally accommodate this scenario. We analyze SUSY UV completions and present a simple Twin SUSY model with a tuning of around 10% and colored superpartners as heavy as 2 TeV. The collider signatures of general Twin SUSY models are discussed with a focus on the extended Higgs sectors.

description: Technical strategies like amino acid substitution and residue modification have been widely used to characterize the importance of key amino acids and the role that each residue plays in the structural and functional properties of protein molecules. However, there is no systematic approach to assess the impact of the substituted/modified amino acids on the conformational dynamics of proteins. In this investigation to clarify the effects of residue modifications on the structural dynamics of human prion protein (PrP), a comparative molecular dynamics simulation study on the native and the amino acid-substituted analog at position 208 of PrP has been performed. It is believed that Arginine to Histidine mutation at position 208 is responsible for the structural transition of the native form of human prion protein to the pathogenic isoform causing Creutzfeldt-Jakob disease (CJD). So, three 10 ns molecular dynamics simulations on three model constructs have been performed. Simulation results indicated considerable differences of conformational fluctuations for Alanine substituted construct (PrPALA) and the analog form (PrPSB) comprising the neutralized state of the Arginine residue at position 208 of the human prion protein. According to our data, substitution of the Arginine residue by the uncharged state of this residue induces some reversible structural alterations in the intrinsically flexible loop area including residues 167–171 of PrP. Thus, deprotonation of Arg208 is a weak perturbation to the structural fluctuations of the protein backbone and the resulting construct behaves almost identical as its native form. Otherwise, Alanine substitution at position 208 imposed an irreversible impact on the secondary and tertiary structure of the protein, which leads to conformational instabilities in the remote hot region comprising residues 190–195 of the C–terminal part of helix 2. Based on the results, it could be deduced that the observed conformational transitions upon Arg208 to His point mutation, which is the main reason for CJD, may be mainly related to the structural instabilities due to the induced-conformational changes that caused alterations in local/spatial arrangements of the force distributions in the backbone of the human prion protein.

description: Quantum physics phenomena, entanglement and coherence, are crucial for quantum information protocols, but understanding these in systems with more than two parts is challenging due to increasing complexity. The W state, a multipartite entangled state, is notable for its robustness and benefits in quantum communication. Here, we generate an 8-mode on-demand single photon W states, using nanowire quantum dots and a silicon nitride photonic chip. We demonstrate a reliable, scalable technique for reconstructing W-state in photonic circuits using Fourier and real-space imaging, supported by the Gerchberg-Saxton phase retrieval algorithm. Additionally, we utilize an entanglement witness to distinguish between mixed and entangled states, thereby affirming the entangled nature of our generated state. The study provides a new imaging approach of assessing multipartite entanglement in W-states, paving the way for further progress in image processing and Fourier-space analysis techniques for complex quantum systems.

description: A search is performed for narrow resonances decaying to final states of two jets, with at least one jet originating from a b quark, in proton-proton collisions at $\sqrt{s}$ = 13 TeV. The data set corresponds to an integrated luminosity of 138 fb$^{-1}$ collected with the CMS detector at the LHC. Jets originating from energetic b hadrons are identified through a b tagging algorithm that utilizes a deep neural network or the presence of a muon inside a jet. The invariant mass spectrum of jet pairs is well described by a smooth parametrization and no evidence for the production of new particles is observed. Upper limits on the production cross section are set for excited b quarks and other resonances decaying to dijet final states containing b quarks. These limits exclude at 95% confidence level models of Z' bosons with masses from 1.8 to 2.4 TeV and of excited b quarks with masses from 1.8 to 4.0 TeV. This is the most stringent exclusion of excited b quarks to date.

description: We present the guarded lambda-calculus, an extension of the simply typed lambda-calculus with guarded recursive and coinductive types. The use of guarded recursive types ensures the productivity of well-typed programs. Guarded recursive types may be transformed into coinductive types by a type-former inspired by modal logic and Atkey-McBride clock quantification, allowing the typing of acausal functions. We give a call-by-name operational semantics for the calculus, and define adequate denotational semantics in the topos of trees. The adequacy proof entails that the evaluation of a program always terminates. We introduce a program logic with Löb induction for reasoning about the contextual equivalence of programs. We demonstrate the expressiveness of the calculus by showing the definability of solutions to Rutten's behavioural differential equations.

description: Results are presented on a search for CP violation in the production and decay of top quark-antiquark pairs in the lepton+jets channel. The search is based on data from proton-proton collisions at 13 TeV, collected with the CMS detector, corresponding to an integrated luminosity of 138 fb$^{-1}$. Possible CP violation effects are evaluated by measuring uncorrected asymmetries in observables constructed from linearly independent four-momentum vectors of the final-state particles. The dimensionless chromoelectric dipole moment of the top quark obtained from the observed asymmetries is measured to be 0.04 $\pm$ 0.10 (stat) $\pm$ 0.07 (syst), and the asymmetries exhibit no evidence for CP-violating effects, consistent with expectations from the standard model.

description: In the process of scientific inquiry, certain claims accumulate enough support to be established as facts. Unfortunately, not every claim accorded the status of fact turns out to be true. In this paper, we model the dynamic process by which claims are canonized as fact through repeated experimental confirmation. The community's confidence in a claim constitutes a Markov process: each successive published result shifts the degree of belief, until sufficient evidence accumulates to accept the claim as fact or to reject it as false. In our model, publication bias --- in which positive results are published preferentially over negative ones --- influences the distribution of published results. We find that when readers do not know the degree of publication bias and thus cannot condition on it, false claims often can be canonized as facts. Unless a sufficient fraction of negative results are published, the scientific process will do a poor job at discriminating false from true claims. This problem is exacerbated when scientists engage in p-hacking, data dredging, and other behaviors that increase the rate at which false positives are published. If negative results become easier to publish as a claim approaches acceptance as a fact, however, true and false claims can be more readily distinguished. To the degree that the model accurately represents current scholarly practice, there will be serious concern about the validity of purported facts in some areas of scientific research.

description: The present thesis is a product of cross-sectoral partnership of the Faculty of Geology, between the Department of Applied Geology (Technical Geology) and the Department of Geophysics. The main object is the verification of the engineering geological conditions in a part of the planned tunnel section of Asvestochori in the area of Retziki (Pefka) of Thessaloniki. The targeted area is significantly complex from a geological point of view, as well as in terms of its technical design parameters, where the conventional method of "mapping" the engineering geological profile of an area fails to provide safe answers to the problems that arise. In addition to the intense tectonic activity, which creates an unclear pattern of stratification of geological formations, we should also consider the variation of quality and condition of rock masses, which create a wide range of heterogeneity of geotechnical features. Indications of presence of cavities and faults in a close proximity to each other, makes it imperative to combine the conventional "tracking" of the engineering geological profile with a geophysical method of the highest possible reliability, which will work ancillary, for the solution of inquiries such as water permeability and the associated risks of inputs, existence of faults and the consequent modification of geological composition in the study area.

description: Introduction: Measles is a leading cause of childhood morbidity and mortality worldwide. An estimated 164,000 people died globally from measles in 2008 mostly children under the age of five. In Ethiopia, the expected case-fatality rate is between 3% and 6%; the highest case-fatality rate occurs in infants 6 to 11 months of age, with malnourished infants at greatest risk. The main aim of this outbreak investigation was to assess the magnitude and risk factor of measles infection in Wadera Woreda of Guji zone, Oromia Region, from 04-19/12/2016. Method: Descriptive cross-sectional followed by case-control study design was used to identify the risk factors. Unmatched case-control sample size determination with a ratio of 1:2 for cases and controls. Result: A total of 393 cases were reported. Six samples were taken and four of them were positive for measles. The Index case was female aged 20 years who was not vaccinated. We detected a period prevalence of 5.93/1000. In the variable analysis having previous measles infection and being vaccinated with measles vaccine has a protective factor with AOR=0.36,95%CI:0.16-0.76,P.value 0.008 and AOR;0.41,95%CI:0.17-0.97,P.value 0.043 respectively. while being under five years old and having contact history with measles cases are a risk factor for developing measles infection with AOR;2.83,95%CI(1.25-6.43),P. value 0.013 and AOR;6.75,95%CI(2.69-16.94),p. value < 0.0001 respectively. Discussion: Periodic measles outbreaks occur when a large number of susceptible accumulate in a community. Susceptible accumulate through time even in the setting of high routine measles vaccination coverage. Conclusion: The main factors contributing to this outbreak was the accumulation of large numbers of susceptible children over time in the Woreda.. Recommendation: Ministry of health, Regional health Bureau and Zonal health department to use the second opportunity of Supplementary Immunization Activities and have conducted a catch up and several follow up campaigns to increase measles immunity by keeping data records at all levels.

description: A measurement is presented of the production of Z bosons that decay into two electrons or muons in association with jets, in proton-proton collisions at a centre-of-mass energy of 13 TeV. The data were recorded by the CMS Collaboration at the LHC with an integrated luminosity of 35.9 fb$^{-1}$. The differential cross sections are measured as a function of the transverse momentum ($p_\mathrm{T}$) of the Z boson and the transverse momentum and rapidities of the five jets with largest $p_\mathrm{T}$. The jet multiplicity distribution is measured for up to eight jets. The hadronic activity in the events is estimated using the scalar sum of the $p_\mathrm{T}$ of all the jets. All measurements are unfolded to the stable particle-level and compared with predictions from various Monte Carlo event generators, as well as with expectations at leading and next-to-leading orders in perturbative quantum chromodynamics.

description: Engineered quantum systems allow us to observe phenomena that are not easily accessible naturally. The LEGO-like nature of superconducting circuits makes them particularly suited for building and coupling artificial atoms. Here, we introduce an artificial molecule, composed of two strongly coupled fluxonium atoms, which possesses a tunable magnetic moment. Using an applied external flux, one can tune the molecule between two regimes: one in which the ground-excited state manifold has a magnetic dipole moment and one in which the ground-excited state manifold has only a magnetic quadrupole moment. By varying the applied external flux, we find the coherence of the molecule to be limited by local flux noise. The ability to engineer and control artificial molecules paves the way for building more complex circuits for protected qubits and quantum simulation.

description: Back ground According to World Health Organization (WHO) 2015 report globally 480 000 new cases and 190,000 estimated deaths occurred in 2014 due to MDR TB. Ethiopia ranked 7th from top 22 highest TB-burden and 15th from 27 highest MDR-TB burden countries; and one of high HIV/AIDS prevalent in Sub-Sahara African countries. Nevertheless, a little known about Survival of Multidrug-resistant Tuberculosis patients with HIV/AIDS co-infection in Ethiopia. Hence, this study is to determine the Survival and their determinants in MDR TB patients co-infected with HIV/AIDS Addis Ababa, Ethiopia Method A retrospective cohort study design was conduct at St. Peter TB specialized hospital Addis Ababa, Ethiopia; from February to March 2016. Survival of exposed and non-exposed groups was compared by Kaplan-Meier survival functions by using log-rank test. Factors that associated with outcome variables at 20 % (p<0.2) significant level in the bivariate analysis was included in the final Multivariable analysis. Cox proportional hazards regression model was used to determine factors associated with risk of death by controlling confounding and effect modifier. Result Out of 93 expose groups 48 (51.61%) were female and the rest 45 (48.39%) were male. Ninety three exposed study subjects were survive for a total of 26,581 person per 10000 days, and 213 non-exposed study subjects were survive for a total of 63,782 person per 10000 days. Median survival time of exposed study subjects was 269 person days and for non-exposed study subjects had 254 person days median survival time. Kaplan Meier survival curve shows lower survival (long-rank test, P<0.010) was seen in exposed groups compared to non-exposed group throughout the follow up time with parallel survival estimate curve. Independently associated factors for increasing risk of death was hospitalization at the time of treatment initiation (HR: 8.64; [1.11 - 67.00]), presence of HIV co-infection (HR: 2.15; [1.04 - 4.46] and age greater than or equal to 65 (HR: 10.07; [1.80 - 56.29]. Conclusion This study find out MDR TB patients without HIV had better survival than those MDR TB patients with HIV co-infection. Hospitalization at the time of treatment initiation, presence of HIV co-infection and age greater than or equal to 65 years of age increase the risk of death. Recommendations Early detection (diagnosis) and treatment for MDR TB for HIV positive patients; regular medical check-up for MDR TB to aged people; decrease hospitalization by early diagnosis and treatment and further studies on MDR TB and survival of older population

description: New sets of parameter tunes for two of the colour reconnection models, quantum chromodynamics-inspired and gluon-move, implemented in the PYTHIA 8 event generator, are obtained based on the default CMS PYTHIA 8 underlying-event tune, CP5. Measurements sensitive to the underlying event performed by the CMS experiment at centre-of-mass energies $\sqrt{s}$ = 7 and 13 TeV, and by the CDF experiment at 1.96 TeV are used to constrain the parameters of colour reconnection models and multiple-parton interactions simultaneously. The new colour reconnection tunes are compared with various measurements at 1.96, 7, 8, and 13 TeV including measurements of the underlying-event, strange-particle multiplicities, jet substructure observables, hadron ratios (from e$^+$e$^-$ colliders), jet shapes, and colour flow in top quark pair ($\mathrm{t\bar{t}}$) events. The new tunes are also used to estimate the uncertainty related to colour reconnection modelling in the top quark mass measurement using the decay products of $\mathrm{t\bar{t}}$ events in the semileptonic channel at 13 TeV.

description: Sowohl die Akanthamöbenkeratitis als auch die bakterielle Keratitis stellen schwerwiegende Infektionen des Auges dar und führen zum Visusverlust. Die Keratitiden müssen frühzeitig erkannt und diagnostiziert werden, um einen komplizierten Verlauf zu verhindern. Besonders die schnelle Erregerdiagnostik stellt einen erheblichen Faktor für das Outcome des Patienten dar. Wenn Methoden wie PCR noch mehr etabliert würden, könnten Therapiestrategien frühzeitiger umgesetzt werden. In dieser Studie wurden 43 bakterielle Keratitiden, 20 Akanthamöbenkeratitiden und neun Mischinfektionen analysiert.
Wang-Landau algorithm for entropic sampling of arch-based microstates in the volume ensemble of static granular packings

description: We implement the Wang-Landau algorithm to sample with equal probabilities the static configurations of a model granular system. The "non-interacting rigid arch model" used is based on the description of static configurations by means of splitting the assembly of grains into sets of stable arches. This technique allows us to build the entropy as a function of the volume of the packing for large systems. We make a special note of the details that have to be considered when defining the microstates and proposing the moves for the correct sampling in these unusual models. We compare our results with previous exact calculations of the model made at moderate system sizes. The technique opens a new opportunity to calculate the entropy of more complex granular models.

description: The double differential cross sections of the Drell-Yan lepton pair ($\ell^+\ell^-$, dielectron or dimuon) production are measured as functions of the invariant mass $m_{\ell\ell}$, transverse momentum $p_\mathrm{T}(\ell\ell)$, and $\phi^*_\eta$. The $\phi^*_\eta$ observable, derived from angular measurements of the leptons and highly correlated with $p_\mathrm{T}(\ell\ell)$, is used to probe the low-$p_\mathrm{T}(\ell\ell)$ region in a complementary way. Dilepton masses up to 1 TeV are investigated. Additionally, a measurement is performed requiring at least one jet in the final state. To benefit from partial cancellation of the systematic uncertainty, the ratios of the differential cross sections for various $m_{\ell\ell}$ ranges to those in the Z mass peak interval are presented. The collected data correspond to an integrated luminosity of 36.3 fb$^{-1}$ of proton-proton collisions recorded with the CMS detector at the LHC at a centre-of-mass energy of 13 TeV. Measurements are compared with predictions based on perturbative quantum chromodynamics, including soft-gluon resummation.

Soldiers of Fortune in Cyberspace & the Governance of Security. The New Wild West?

description: In today’s security architectures, providing safety and security is not the monopoly of the state. Various other actors have emerged in what some would call a fragmented security landscape. As of the 1970s, scholars have developed theories on governance which try to explain the nature of these evolutions and the relationship between the different public and private security providers. Recent evolutions in the field of warfare and crime control are, however, inviting researchers to revisit these theories. This research project accepts the invitation by studying the cyber dimension of warfare and crime manifested in the phenomenon of cyber mercenaries: individuals or groups who launch cyber- attacks on demand which serve either criminal, political, or military objectives. In doing so, the lines between cyberwar and -crime are being blurred, which is a key component of today’s hybrid warfare. The question arises whether or not contemporary theories on governance are still relevant in a cyber environment, to what extent “new” actors such as cyber security companies are involved in governance architectures, and what their theoretical and practical impact could be. Based on qualitative methods, such as case studies, interviews, network- and document analysis, the proposed research seeks to gain new insights into the application of governance architectures regarding cyber mercenaries and hence to contribute to the existing scholarship on criminology, law, and international relations.

description: Background The main causes of under- five children morbidity and mortality in developing countries are related to exposures to poor environmental, socio-demographic and behavioral factors. Contaminated water consumption and poor hygienic practices are the leading causes of death among children worldwide especially in developing countries, including Ethiopia. Objective To assess the prevalence and associated factors for the occurrence of diarrhea disease among under-five year's children Method A Cross sectional study conducted in Woreda 03 Residence of Yeka sub city of Addis Ababa Ethiopia whereby 399 out of 400targeted sample households' caretaker with under- five children were interviewed by trained data collectors and alsofrom 34 household who have under- five children with diarrhea sample water were taken from usual water storage and examined and the collected data was entered using Epi Info and cleaned and analyzed using SPSS.Bivariate and multivariate logistic regression analyses were undertaken to identify factors for childhood diarrhea. Result prevalence of diarrhea in under-five children was found 8.5 percent of the total 399 children from the socioeconomic variables entered the age of mother less than twenty five[AOR: 7.42, 95% CI: (1.64, 33.60)], from the Environmental variables entered in the model those house hold got water more than two week[AOR:4.56, 95% CI: (1.49, 13.93)] and from behavioral variables entered in the model caretaker who said I wash my hands after cleansing baby bottom and after using toilet [AOR:0.36, 95% CI: (0.15, 0.84)] and [AOR:0.23, 95% CI: (0.55, 0.96)]and also those caretaker who said I dispose child feces anywhere by covering with soil [AOR:0.7.9, 95% CI: (1.05, 59.89)]had significant in the final step or model. And the examined water sample result showed that from Ecoli point of view from thirty four 21 and from total coliform point from thirty four 29 sample showed unacceptable result Conclusions and Recommendations Storing water for long time and not practicing of washing hands after cleansing baby bottom and after using toile and also disposing child feces by covering with soil were risk factors for the occurrence of diarrhea in under-five children. Therefore Knowledge and practice on hand washing at critical times should have to get great emphasis during health education in order to protect the children against diarrhea and also the demand and supply of water supply gap should be minimized

description: Der Einsatz digitaler Werkzeuge beeinflusst den Mathematikunterricht auf vielen Ebenen. Lerman (2013, S.41) stellt heraus, dass sich die Forschung in diesem Bereich jedoch meist auf die Einsatzmöglichkeiten, die Unterrichtsplanung und praktische Umsetzung richtet. Die potenziell tiefgreifenden Veränderungen des Lernens von Mathematik und der gelernten Mathematik wurden dabei noch nicht in ausreichendem Maße tiefergehend analysiert. In diesem Artikel sollen zunächst die theoretische Fundierung der Fragestellung dargestellt und eine Studie zur explorativen Untersuchung mit ersten Beobachtungen vorgestellt werden.
