    Dual Training System Integration for Caregiver School in Cebu City  [PDF]
    Leovigilda L. Bithay
    Open Access Library Journal (OALib Journal) , 2020, DOI: 10.4236/oalib.1106002
    Abstract:
    This research assessed the integration of the Technical Education Skills Development Authority (TESDA) Dual Training System of the identified Caregiver Schools in Cebu City, Philippines. This is anchored on Christian Wolff’s theory that the mind has mental powers or faculties such as memory, reason, judgment, attention, will and observation; these functions have separate entity that can be improved through exercise or use. The respondent groups of this research were clustered into three (3) as to trainers, clinical instructors and trainees from three (3) caregiver schools and two (2) affiliated hospitals. It utilized the descriptive method with the TESDA adopted survey questionnaire as the instrument. The statistical treatments used were simple percentage, weighted mean and T-test. The findings revealed that the educational qualification and achievements of the trainers and clinical instructors met the prescribed competencies required by TESDA. Hence the Dual Training System (DTS) competency-based curriculum was Fully Delivered with an average weighted mean of 2.41 to the trainee respondent groups. The level of the DTS competency-based curriculum implementation as to basic, common and core competencies had a weighted mean of 2.91 described as Fully Implemented. There is a significant relationship between the trainees’ in-bound rating of a weighted mean grade of 88 and DTS performance rating with a weighted mean grade of 90. There is no significant difference as to the perceptions on the extent of DTS competency-based curriculum implementation among the respondent groups. Thus, it is concluded that the integration of the Dual Training System Competency-Based Curriculum improved the trainees’ performance. Thus, the Training Manual which is the output of this research is highly recommended.
    Computing Reachable Sets as Capture-Viability Kernels in Reverse Time
    No?l Bonneuil
    Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.311219
    Abstract: The set SF(x0;T) of states y reachable from a given state x0 at time T under a set-valued dynamic x’(t)∈F(x (t)) and under constraints x(t)∈K where K is a closed set, is also the capture-viability kernel of x0 at T in reverse time of the target {x0} while remaining in K. In dimension up to three, Saint-Pierre’s viability algorithm is well-adapted; for higher dimensions, Bonneuil’s viability algorithm is better suited. It is used on a large-dimensional example.
    Three Dimensional Evolution of SN 1987A in a Self-Gravitating Disk
    L. Zaninetti
    International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.32010
    Abstract:

    The introduction of an exponential or power law gradient in the interstellar medium (ISM) allows to produce an asymmetric evolution of the supernova remnant (SNR) when the framework of the thin layer approximation is adopted. Unfortunately both the exponential and power law gradients for the ISM do not have a well defined physical meaning. The physics conversely is well represented by an isothermal self-gravitating disk of particles whose velocity is everywhere Maxwellian. We derived a law of motion in the framework of the thin layer approximation with a control parameter of the swept mass. The photon’s losses, which are often neglected in the thin layer approximation, are modeled trough velocity dependence. The developed framework is applied to SNR 1987A and the three observed rings are simulated.

    The Luminosity Function of Galaxies as Modeled by a Left Truncated Beta Distribution
    L. Zaninetti
    International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.41013
    Abstract: A first new luminosity function of galaxies can be built starting from a left truncated beta probability density function, which is characterized by four parameters. In the astrophysical conversion, the number of parameters increases by one, due to the addition of the overall density of galaxies. A second new galaxy luminosity function is built starting from a left truncated beta probability for the mass of galaxies once a simple nonlinear relationship between mass and luminosity is assumed; in this case the number of parameters is six because the overall density of galaxies and a parameter that regulates mass and luminosity are added. The two new galaxy luminosity functions with finite boundaries were tested on the Sloan Digital Sky Survey (SDSS) in five different bands; the results produce a better fit than the Schechter luminosity function in two of the five bands considered. A modified Schechter luminosity function with four parameters has been also analyzed.
    On the Dark Matter’s Halo Theoretical Description
    L. M. L. M. Chechin
    Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.35052
    Abstract: We argued that the standard field scalar potential couldn’t be widely used for getting the adequate galaxies’ curve lines and determining the profiles of dark matter their halo. For discovering the global properties of scalar fields that can describe the observable characteristics of dark matter on the cosmological space and time scales, we propose the simplest form of central symmetric potential celestial-mechanical type, i.e. U(φ) = –μ/φ. It was shown that this potential allows get rather satisfactorily dark matter profiles and rotational curves lines for dwarf galaxies. The good agreement with some previous results, based on the N-body simulation method, was pointed out. A new possibility of dwarf galaxies’ masses estimation was given, also.
    Analytical Approximation to the Dynamics of a Binary Stars System with Time Depending Mass Variation
    Gustavo V. López, Elkin L. López
    Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.63053
    Abstract: We study the classical dynamics of binary stars when there is an interchange of mass between them. Assuming that one of the stars is more massive than others, the dynamics of the lighter one is analyzed as a function of its time depending mass variation. Within our approximations and models for mass transference, we obtain a general result which establishes that if the lightest star looses mass, its period increases. If the lightest star wins mass, its period decreases.
    Quantization and Stable Attractors in a DissipativeOrbital Motion
    Daniel L. Nascimento, Antonio L. A. Fonseca
    Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.24030
    Abstract: We present a method for determining the motion of an electron in a hydrogen atom, which starts from a field Lagrangean foundation for non-conservative systems that can exhibit chaotic behavior. As a consequence, the problem of the formation of the atom becomes the problem of finding the possible stable orbital attractors and the associated transition paths through which the electron mechanical energy varies continuously until a stable energy state is reached.
    Genetic and dietary factors related to schizophrenia
    Karl L. Reichelt, Michael L. G. Gardner
    Open Journal of Psychiatry (OJPsych) , 2012, DOI: 10.4236/ojpsych.2012.21003
    Abstract: Biochemical, immunological and epidemiological evidence increasingly support the suggestion that there is a causal relationship between gluten/gliadin and schizophrenia as originally proposed by F. C. Dohan. Furthermore the necessary physiological mechanisms exist to explain a mechanism involving bioactive peptides from these proteins, and these show that this mechanism is possible and probable in at least in a substantial subgroup of schizophrenic patients. Evidence shows a fairly strong genetic disposition, and it must be recognised that any genetic mechanism must implicate altered chemistry and function of proteins. Evidence supports the likelihood that dietary intervention is beneficial for some, and this demands further investigation. A similar conclusion may apply to autism spectrum conditions.
    Study of Decoherence of Elementary Gates Implemented in a Chain of Few Nuclear Spins Quantum Computer Model
    G. V. López, P. López
    Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.31013
    Abstract: We study the phenomenon of decoherence during the operation of one qubit transformation, controlled-not (CNOT) and controlled-controlled-not (C2NOT) quantum gates in a quantum computer model formed by a linear chain of three nuclear spins system. We make this study with different type of environments, and we determine the associated decoherence time as a function of the dissipative parameter. We found that the dissipation parameter to get a well defined quantum gates (without significant decoherence) must be within the range of . We also study the behavior of the purity parameter for these gates and different environments and found linear or quadratic decays of this parameter depending on the type of environments.
    Chemical and Geological Control on Surface Water within the Shade River Watershed in Southeastern Ohio
    Prosper Gbolo, Dina L. López
    Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.41001
    Abstract:

    The under-sampled middle and western branches of Shade River Watershed (SRW) in SE Ohio were investigated as part of the Ohio University—U.S. Environmental Protection Agency (EPA) STAR grant. This project was for monitoring the quality of watersheds in Ohio and classifying them according to their physical, chemical, and biological conditions. Water samples, as well as field parameters, were taken at twenty-two sites for chemical analyses. The ions analyzed included Ca, Mg, Na, Fe, Mn, Al, NO3, SO4, HCO3, and total PO4, while the field parameters measured included pH, dissolved oxygen (DO), total dissolved solids (TDS), electrical conductivity (EC), and alkalinity. To assess the water quality within the SRW, the analyzed ions and field parameters were compared to the USEPA criteria for the survival of aquatic life. Analytical results showed that the watershed is dominated by Ca-HCO3waters with DO, Fe, Mn, and PO4being the main causes of impairment within the streams. The relatively elevated concentrations of manganese and less extent iron may be associated with the local geology and the acidic nature of the soils. The high alkalinity and calcium concentrations are due to the limestone geology. The elevated phosphate concentration may be due to anthropogenic sources, fertilizers, or contributions from phosphorus-rich bedrock that differs geochemically from other areas.
