    介護概論における介護過程の概念に関する諸説の検討

    Get PDF
    研究ノート介護保険の導入とカリキュラム改正に合わせて改訂された介護概論のテキストを用い、その内容について比較検討を行った。比較した内容は介護過程の意義、定義、展開過程の説明の仕方、介護保険におけるケアプランとの相違、事例の取り上げ方等である。多くのテキストで共通していたことは思考過程としての介護過程であった。しかし、介護福祉における介護過程の位置づけや介護保険制度におけるケアマネジメントとの関係性、事例の取り上げ方など、それぞれのテキストにおいてばらつきがみられた。介護保険制度におけるケアマネジメントの考え方に強く影響されたものや社会福祉援助技術の個別援助過程の考え方に影響された書き方をしているものもあった。介護過程の展開例を示しているものも多かったが、ケアマネジメントを意識したものは、介護福祉を訪問介護(ホームヘルパー)に限定していた。介護過程についての統一した見解が見られない根本的な原因として考えられたことは、介護福祉の専門性の不明瞭さにあると考えられた。介護福祉の根幹ともいえる介護過程について、介護福祉士自らがその専門性に基づいた思考を展開することが望まれた

    本研究では,文部省の新旧体カテストのうち,立ち幅とびと垂直とび,長座体前屈と立位体前屈の比較をすることを目的とした。この課題を明らかにするために,女子学生423人を対象として,体育館にて上記の項目において測定を行い,その測定結果,および方法の比較について検討した。おもな結果は,以下の通りである。1.立ち幅とびと垂直とびの相関係数は0.66で高い相関関係がみられた。2.長座体前屈と立位体前屈の相関係数は0.62で高い相関関係がみられた。以上の結果から,立ち幅とびと垂直とび,長座体前屈と立位体前屈の測定結果については,高い相関関係が得られた。これらの測定は,測定の容易さや高年齢者の配慮などの点から新体カテストは有効であると考えられる。さらに,これらの測定を行う場合は,場所,設備,時間などを考慮し測定項目を選択する必要がある

    The Tokyo metropolitan area is under constant threat of strong ground motions from future plate-boundary earthquakes along the subducting Philippine sea slab. Here, we upgrade a ground motion simulation of the 1923 Kanto earthquake using a source model along the new geometry of the Philippine sea slab, geophysical-based velocity model, and effcient computational tool. The source process was inferred from strong-motion, teleseismic, and geodetic data with the new geometry of the slab. The 3D velocity-structure model beneath the Tokyo metropolitan area has been constructed using integrating refraction, reflection, borehole, microtremor, and gravity data, as well as ground motion spectra. We introduce a low-frequency ground motion simulation using these models and the finite element method with a voxel mesh. The western basin edge complicated wave propagation, and excited long-period motions were found within the basin. We confirmed that the simulated ground motions are sensitive to the distribution of asperities of the source model along the shallower plate geometry where the eastern major asperity is located closer to downtown Tokyo than in previous models. Because high-frequency components are essential for seismic intensity measurements, source modeling using the pseudo-dynamic approach and ground-motion simulation using the hybrid method combining deterministic and stochastic approaches are strong candidates to complete a broadband ground motion simulation

    Isotope effect in transient electron thermal transport property and its impact on the electron internal transport barrier formation in LHD

    In this study, we perform a comprehensive comparison of the transport hysteresis width in deuterium (D) plasmas, hydrogen (H) plasmas, and D-H mixed plasmas. The core focused modulation electron cyclotron resonance heating (MECH) is applied as the heat source perturbation, and the heat flux is evaluated using the energy conservation equation with the measured electron temperature response and the ECH deposition profile calculated by the ray-tracing scheme. Systematic density scan in plasmas with different ion mass reveals that there is no significant isotope effect in their hysteresis width. It is found that plasmas with heavier isotope mass can easily form the electron internal transport barrier. As the hysteresis width is insensitive to the isotope mass, the classical part of the diffusivity is considered to be responsible for the isotope effect in the transport barrier formation

    Correcting for non-periodic behaviour in perturbative experiments: application to heat pulse propagation and modulated gas-puff experiments

    This paper introduces a recent innovation in dealing with non-periodic behavior often referred to as transients in perturbative experiments. These transients can be the result from the unforced response due to the initial condition and other slow trends in the measurement data and are a source of error when performing and interpreting Fourier spectra. Fourier analysis is particularly relevant in system identification used to build feedback controllers and the analysis of various pulsed experiments such as heat pulse propagation studies. The basic idea behind the methodology is that transients are continuous complex-valued smooth functions in the Fourier domain which can be estimated from the Fourier data. Then, these smooth functions can be subtracted from the data such that only periodic components are retained. The merit of the approach is shown in two experimental examples, i.e. heat pulse propagation (core transport analysis) and radiation front movement due to gas puffing in the divertor. The examples show that the quality of the data is significantly improved such that it allows for new interpretation of the results even for non-ideal measurements

    Development and application of a ray-tracing code integrating with 3D equilibrium mapping in LHD ECH experiments

    The central electron temperature has successfully reached up to 7.5 keV in large helical device(LHD) plasmas with a central high-ion temperature of 5 keV and a central electron density of1.3×1019 m−3. This result was obtained by heating with a newly-installed 154 GHz gyrotronand also the optimisation of injection geometry in electron cyclotron heating (ECH). Theoptimisation was carried out by using the ray-tracing code ‘LHDGauss’, which was upgradedto include the rapid post-processing three-dimensional (3D) equilibrium mapping obtainedfrom experiments. For ray-tracing calculations, LHDGauss can automatically read the relevantdata registered in the LHD database after a discharge, such as ECH injection settings (e.g.Gaussian beam parameters, target positions, polarisation and ECH power) and Thomsonscattering diagnostic data along with the 3D equilibrium mapping data. The equilibrium mapof the electron density and temperature profiles are then extrapolated into the region outsidethe last closed flux surface. Mode purity, or the ratio between the ordinary mode and theextraordinary mode, is obtained by calculating the 1D full-wave equation along the directionof the rays from the antenna to the absorption target point. Using the virtual magnetic fluxsurfaces, the effects of the modelled density profiles and the magnetic shear at the peripheralregion with a given polarisation are taken into account. Power deposition profiles calculatedfor each Thomson scattering measurement timing are registered in the LHD database. Theadjustment of the injection settings for the desired deposition profile from the feedbackprovided on a shot-by-shot basis resulted in an effective experimental procedure
