TY - JOUR A1 - Shaw, L. A1 - Campbell, H. A1 - Jacobs, K. A1 - Prodinger, Birgit T1 - Twenty years of Assessment in WORK: A narrative review JF - Work N2 - Introduction: The aim of this review was to gain an understanding of the first 20 years of contributions to WORK within the assessment domain and to reflect on the perspectives underscoring this knowledge base. Method: A narrative review of assessment articles using the WORK ARTicle database was conducted. Assessment articles were searched using issues from 1990 to 2009. Descriptive data was analyzed to examine historical trends of the specific types and dimensions of articles, the regional location of the contributions, and the methodological accordance. A reflective process was used by an editorial board member of WORK to inductively interpret perspectives and contextual issues that underpinned the evolution of the assessment domain in WORK. Results: Over half of N= 108 of the articles on assessment in WORK focused on establishing or reporting reliability and validity of assessments used in clinical practice or evaluation research. The majority of the assessment articles were predominantly focused on the person. Contributions of articles were from 5 regions: North America, Europe, Australia, Asia and Africa. Conclusions: Assessment articles in WORK have contributed to the development of evidence to support assessment of the worker. These articles represent a knowledge base that emphasizes evidence-based assessments to evaluate what a person can and cannot do to participate in work. Efforts are needed to expand knowledge generation in assessment to include more evaluations on the workplace and occupation dimensions, and that also considers the worker in context.

A1 - Prodinger, Birgit T1 - Strengthening quality of care through standardized reporting based on the World Health Organization's reference classifications JF - International Journal of Quality in Health N2 - Quality issue Responding to person's health and related needs requires the availability of health information that reflects relevant aspects of a health condition and how this health condition impacts on a person's daily life. Initial assessment Health information is routinely collected at different time points by diverse professionals, in different settings for various purposes with varying methods. Consequently, health information is not always comparable, posing a challenge to the regular monitoring of quality. Choice of solution The World Health Organization's (WHO) International Classification of Diseases (ICD), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI; under development) are complementary and serve as meaningful reference classifications for comparing data on persons’ health and related interventions across health systems. Implementation We developed a systematic approach of translating routinely collected information into a standardized report based on the three WHO reference classifications and the Rehab-Cycle®. Subsequently, we have demonstrated its application using five random case records of individuals attending a rehabilitation program. Evaluation All identified concepts were able to be linked to WHO's reference classifications. The ICF served as a tool to standardize information on rehabilitation goals and their achievement. The ICHI served as the basis for reporting the interventions that were documented in the case records, including the intervention targets that were derived from the ICF codes. Lessons learned Our experience shows that, it is possible to translate routinely collected information into standardized reports by linking existing narrative records with WHO's reference classifications.

T1 - Harmonizing routinely collected health information for strengthening quality management in health systems: requirements and practice JF - Journal of Health Services Research & Policy N2 - Objective Our aim was to specify the requirements of an architecture to serve as the foundation for standardized reporting of health information and to provide an exemplary application of this architecture. Methods The World Health Organization’s International Classification of Functioning, Disability and Health (ICF) served as the conceptual framework. Methods to establish content comparability were the ICF Linking Rules. The Rasch measurement model, as a special case of additive conjoint measurement, which satisfies the required criteria for fundamental measurement, allowed for the development of a common metric foundation for measurement unit conversion. Secondary analysis of data from the North Yorkshire Survey was used to illustrate these methods. Patients completed three instruments and the items were linked to the ICF. The Rasch measurement model was applied, first to each scale, and then to items across scales which were linked to a common domain. Results Based on the linking of items to the ICF, the majority of items were grouped into two domains, Mobility and Self-care. Analysis of the individual scales and of items linked to a common domain across scales satisfied the requirements of the Rasch measurement model. The measurement unit conversion between items from the three instruments linked to the Mobility and Self-care domains, respectively, was demonstrated. Conclusions The realization of an ICF-based architecture for information on patients’ functioning enables harmonization of health information while allowing clinicians and researchers to continue using their existing instruments. This architecture will facilitate access to comprehensive and consistently reported health information to serve as the foundation for informed decision-making.

Part 2: Measurement-Based Investigation of the Sound Radiation of Suspended Ceilings T2 - Deutsche Gesellschaft für Akustik e.V. (ed.), Fortschritte der Akustik - DAGA N2 - In this contribution a method for the prediction of the radiated sound out of the velocity field of a vibrating ceiling is presented. The numerical method was validated via measurements on a real structure using a pp-probe. It is based on Integral Transform techniques and can be applied in the postprocessing of a FEM simulation (harmonic analysis) [1]. The method was verified by measurements on the real structure and can be used for parametrical studies. Rounding off the Parts 1 and 2 of this publication nomograms, based on dimensionless parameters, can be developed to predict the sound radiation of light weight slabs. Hereby different sets of geometry as well as different configurations of ceilings can be studied in order to describe the acoustical and dynamical behaviour of wooden ceilings.

Part 1: Aspects of Numerical Modeling, Model Updating and Parametric Studies using the Buckingham π -Theorem T2 - Deutsche Gesellschaft für Akustik e.V. (ed.), AIA-DAGA N2 - In order to set up guidelines for the design of light-weighted ceilings for timber constructions to be used by engineers in practice, investigations based on both measurements and numerical models have been carried out [1, 2, 3]. The setup and the calibration of the numerical model of the structure are outlined briefly. A semi-analytical approach for the prediction of radiated sound is presented, which is based on Integral Transform Methods. The method can be applied in the post processing of a Finite Element computation. Thus as a first step the structure, consisting of a timber slab, a floating floor and a suspended ceiling, is built up in a Finite Element model, where the material properties of wood and the characteristics of the system are considered. The model is parameterized in order to enable computations with varying geometry and material parameters and calibrated with the help of measurements using model updating techniques. The velocity pattern resulting out of the FEM computation is transformed from the spatial into the wavenumber domain and from the time into the frequency domain using Fourier Transform Methods. Applying this velocity pattern as a boundary condition to the Helmholtz Equation, which results out of the Fourier Transform of the wave equation, the wavenumbers, which fulfil the radiation condition, can be selected and the pressure field in the adjacent acoustic fluid can be computed. Due to the properties of the Fourier-Transform the radiated sound power can be calculated efficiently in the transformed domain out of pressure and velocity. In a second part of the contribution the model for the air cushion in the suspended ceiling is discussed, where a FSI-model for the acoustic fluid and the structure is compared against engineering approaches using simplifications concerning mass distribution and transfer impedances between the individual nodes at the interface KW - Schallmesstechnik KW - Holzbau Y1 - 2013 ER - TY - CHAP A1 - Kohrmann, M.

In this contribution the setup and the calibration of the numerical model of the structure as well as the prediction of radiated sound are discussed, where a special focus is set on a dimensionless description in order to deduce information for a wide range of system’s specifications. The structure, consisting of a timber slab, a floating floor and a suspended ceiling, is built up in a Finite Element model, where the material properties of wood and the characteristics of the system (e.g.support conditions, contact phenomena dynamic properties of individual parts) are considered. The model is parameterized in order to enable computations with varying geometry and material parameters. After calibrating the FE-model with the help of measurements using model updating techniques dimensionless parameters are defined based on the Buckingham-π- Theorem and computations are carried out in order to specify guidelines for various systems.

A1 - Schanda, Ulrich T1 - Modelling the Sound Transmission across Junctions of Building Components by Energy Influence Coefficients T2 - European Association for Structural Dynamics (ed.), EURODYN N2 - A trend towards lightweight structures, e.g. timber structures, is noticeable in civil engineering, which implies the necessity to predict vibroacoustic characteristics like the transmission of structure-borne sound in order to fulfil requirements regarding serviceability. This contribution focuses on the investigation of junctions of building components e.g. between wall and ceiling. It is part of a joint research project with the aim to catalogue the coupling for a variety of junctions. The resulting database may serve to predict the transmission of structure-borne sound which is typically carried out either using a Finite Element (FEM) approach, suitable for the low frequency range, or by means of energy methods like the Statistical Energy Analysis (SEA) for the high frequency range. Therefore the so-called mid frequency gap emerges, which is examined and attempted to be closed. In this context SEA-averaging techniques are applied in the postprocessing of FEM calculations to obtain an adapted “SEAlike” approach. By varying the subsystems to be excited it is possible to determine Energy Influence Coefficients (EIC), which describe the specific energy content of the different subsystems with respect to the input power. Using this hybrid approach vibroacoustic predictions can be performed also in the mid frequency range. Inverting the EIC-matrix Coupling Loss Factors as well as Damping Loss Factors of the different subsystems can be calculated if the subsystem definition fulfils the SEA-requirements. The application of the method in combination to a classical SEA calculation and to laboratory measurements is presented. KW - Schallmesstechnik KW - Holzbau Y1 - 2014 ER - TY - CHAP A1 - Völtl, R.

T1 - Simultaneous operational vibration analysis of different layers of lightweight timber floors T2 - Internoise 2013 N2 - Within the scope of the research project "VibWood", operational vibration analyses of timber floor constructions were carried out. In order to understand the vibration behaviour of and the sound transmission through the layers of the constructions the coupling between them was investigated. The transfer function from the point of excitation to a pattern of receiving positions located on each of the layers of the construction was measured using a swept sine excitation. As a result, the frequency range of decoupling between the base floor and the floating floor and between the base floor and the suspended ceiling could be identified and the individual vibration behavior analyzed. The measurements also included the radiated sound power from the suspended ceiling. There is indication that there is not necessarily a correlation between the eigenmodes of the suspended ceiling and the maxima of the radiated sound power KW - Schallmesstechnik KW - Holzbau Y1 - 2018 ER - TY - RPRT A1 - Kohrmann, M.

Based on a vast parametric study including floating floors and suspended ceilings a database of narrowband sound power levels in the frequency range up to 125 Hz for a wide range of floor dimensions has been set up. A procedure will be presented on how to process the numerical data and derive single number values that allow a comparison to the standardized rating of impact sound insulation according to DIN EN ISO 717-2. The derived data is implemented into a graphical user interface (GUI). This GUI is available for free. The database is open for additional geometries and will be enhanced by different constructions in the near future.

However, the modeling of assembled cross-laminated timber components has been studied only scarcely. The three-dimensional p-version of the finite element method, which is characterized by hierarchic high-order shape functions, is well suited to consider coupling and support conditions. Furthermore, a small number of degrees of freedom can be obtained in case of thin-walled structures using p-elements with high aspect ratios and anisotropic ansatz spaces. In this article, a model for cross-laminated timber assemblies made of volumetric high-order finite elements is presented. Two representative types of connections are investigated, one with an elastomer between the cross-laminated timber components and the other without. The model is validated, and suitable ranges for the stiffness parameters of the finite elements which represent the junctions are identified.
