Vocational rehabilitation in patients with chronic rheumatic diseases: a systematic literature review.

OBJECTIVE To describe the effectiveness of vocational rehabilitation programs for patients with chronic rheumatic diseases by means of a systematic review of the literature. METHODS Data were obtained by a computer-aided and manual search of the literature from 1980 until May 2001. Vocational rehabilitation programs had to be clearly defined interventions specifically aimed at having patients with rheumatic diseases reenter or remain in the work force. The vocational rehabilitation programs had to be executed by one or more health professionals. Outcome of the intervention had to be described in terms of vocational status (work disability, sick leave, job modification, paid occupation, retraining). RESULTS Six studies were identified. All were uncontrolled studies. Follow-up periods ranged 2-84 months. Five of six vocational rehabilitation programs consisted of multidisciplinary intervention and 15% to 69% of the patients successfully returned to work. CONCLUSIONS Although 5 of 6 studies showed a marked positive effect of vocational rehabilitation on work status, proof of the benefit of these interventions is limited, mainly due to methodologic differences and shortcomings. RELEVANCE Work disability is a major consequence of the disease in patients with rheumatic conditions. More and more attention is being paid to preventing disability and promoting return to work. Knowledge regarding the effectiveness of vocational rehabilitation programs is insufficient. Semin Arthritis Rheum 32:196-203.
Factors Affecting E-Government Assimilation in Developing Countries

The Information Technology (IT) must be successfully assimilated into the organization in order to exploit its potential value and benefit for their target adopter. This paper examines the factors affecting assimilation of e-Government in Developing Countries. A conceptual framework was developed for analyzing the assimilation of e-government, in the context of IT innovation, which developed based on Technological-Organizational-Environmental (TOE) Framework, Innovation and Diffusion Theory. In this paper, we analyze assimilation as single stage technology diffusion process. An Innovation diffusion theory is coined with TOE framework to explain how assimilation process affected by ICT expertise, ICT infrastructure, TOP management support, organizational compatibility, extend coordination, regulatory environment, and competition. Based on this framework and by utilizing data from questioner, the determinants and mechanisms of this process are identified and process of e-Government assimilation is reconstructed. Questionnaires were distributed among ITTP students at KAIST University as the main respondent, and supported by international student network. The respondents selected from Government Officer from developing countries to response the assimilation process and condition occurred in their respective country. Our research found, the environmental context plays an important role in assimilation of e-Government, followed by organization and technological factors. At the end, our research revealed TOE framework can be use as a method to analyze assimilation of e-Government and contribute a new understanding and model enhancement for academics as well as practitioners and policy maker.
"A capite ad calcem".

In 1881, Edward Mussey Hartwell stated, “So, physicians, indeed, before they endeavor to care for the human body and preserve it from the diseases which threaten it, ought to know very accurately, and to a nicety, all the parts of the body. ” These words mark the essence of clinical anatomy. This issue of our journal Clinical Anatomy continues to explore many topics that are salient to you as educators, researchers and clinicians. These topics include the history of anatomy with a cathartic paper on the research performed on executed Germans during the Third Reich by Dr. Sabine Hildebrandt and a review of the laboratory of the infamous Eduard Pernkopf by Drs. Aharinejad and Carmichael. Other papers presented in this issue describe methods for teaching better dissection courses and understanding pelvic anatomy with 3D modeling for improved medical education and surgical training, and anatomic findings pertinent to our understanding of the fat of the face and surgery of the colon, pelvis, and midfoot – Indeed, topics that run the gamut from head to toe, A capite ad calcem. I hope that you will find such papers enlightening and useful to you in your teaching, research or practice of clinical anatomy.
Advantages of InGaN Solar Cells With p-Doped and High-Al-Content Superlattice AlGaN Barriers

In this letter, the photovoltaic characteristics of InGaN/AlGaN superlattice solar cells with In=21% and 40% in InGaN multiple quantum wells, and Al=14% and 20% in AlGaN barriers are investigated. The results obtained numerically show that an increment of 18.2% in short-circuit current density is achieved by introducing p-type doped (hole&nbsp;concentration = 3×10<sup>17</sup> cm<sup>-3</sup>) Al<sub>0.2</sub>Ga<sub>0.8</sub>N barriers in In<sub>0.4</sub>Ga<sub>0.6</sub>N superlattice solar cell when compared with undoped Al<sub>0.14</sub>Ga<sub>0.86</sub>N barriers. This improvement is mainly attributed to the increased electric field in the main absorption region, which is beneficial for the holes in the valence band to move towards the p-region. The capability of carrier transport is efficiently improved, thus increasing the carrier-collection efficiency and the conversion efficiency.
The key to valid computer-based testing : the user interface

Although in dramatic growth, computer-based testing (CBT) is the target of concerns regarding a central element of its paradigm: test item presentation. In essence, its equivalency respective to other forms of psychological assessment is becoming questioned. Here, CBT item presentation is portrayed as an extremely complex fusion of perceptual, cognitive and psychological dyna;ics requiring considerable professional expertise in its design and application. If its presentation surface is not designed correctly, CBT can result in lowered test performance and reduced validity.
Successful Transpedicular Lumbar Interbody Fusion by Means of a Composite of Osteogenic Protein-1 (rhBMP-7) and Hydroxyapatite Carrier: A Comparison With Autograft and Hydroxyapatite in the Sheep Spine

Study Design. Transpedicular lumbar interbody fusion (TLIF) was performed in a sheep model comparing three treatment groups: a composite of osteogenic protein (OP)-1 and hydroxyapatite carrier (HA), HA without OP-1, and autograft. Objective. To evaluate the efficacy of the composite of OP-1 and HA (HA-OP-1) in achieving reliable TLIF. Summary of Background Data. Anterior fusion techniques directly address disc-related problems and achieve primary axial stability. However, they are characterized by high morbidity. Alternatively, the theoretically advantageous posterior TLIF technique using autograft fails clinically because it lacks compressive stability. Methods. In 36 sheep, lumbar vertebrae L4 to L6 were instrumented posteriorly. Endoscopically assisted TLIF of L4 to L5 was performed. In 12 sheep, the defect was filled with injectable HA-OP-1. Another 12 sheep were treated with HA and another 12 with autograft. Animals were killed at 8 weeks and evaluated by radiologic, histologic, and histomorphometric analysis and by fluorochrome labeling. Results. Only 10 autograft sheep were available for evaluation. Radiologically and histologically, TLIF with HA-OP-1 led to a fusion rate of 10 in 12 compared with autograft (one in 10 fused) and HA (two in 12 fused) (P = 0.0016). Semiquantitative radiologic and histologic scoring also revealed significant differences with superiority of HA-OP-1 (P = 0.0011). Compared with HA, HA-OP-1 presented significantly more ossification at the bone-cement interface (P = 0.0003) and less cement resorption (P = 0.0209). In four of 12 HA sheep, excessive resorption was responsible for local aseptic inflammation. Conclusions. Biointegration of the osteoconductive HA does not occur, because shear forces cause early HA fracture, subsequent fragmentation, and gross resorption (initiating severe inflammation in four of 12 sheep). In contrast, osteoinductive effects of HA-OP-1 enable bio-integration, resulting in full osseous composite sheathing and solid fusion. By use of this composite, TLIF is successfully applied in sheep. Harvesting autograft and the anterior approach are avoided.
The Efficacy of InSight Cognitive Training to Improve Useful Field of View Performance: A Brief Report.

OBJECTIVE It is well established that cognitive speed of processing training (SOPT) improves Useful Field of View (UFOV) performance and transfers to enhanced performance of instrumental activities of daily living, including driving. InSight is a recently developed version of SOPT formatted for self-administration by older adults with exercises translated into a gaming format. The goal was to examine whether InSight training improves UFOV performance. METHOD Participants ranged in age between 59-95 years and were randomized to InSight cognitive training or a control condition. Cognitive performance and self-perceptions were measured pre- and post-training, or for controls, after an equivalent delay. Participants completed training twice a week over a 12-week period with the goal of completing 20 sessions. RESULTS Participants randomized to InSight training experienced greater improvements in their UFOV performance relative to the control condition, F(1, 58) = 4.26, p = . 043, but no changes in cognitive self-perceptions were found. CONCLUSIONS The InSight program is a viable tool for enhancing older adults' UFOV performance. Future research should examine if training gains from the program endure and transfer to improved everyday function.

The Impact of Hydrodynamic Mixing on Supernova Progenitors

Recent multidimensional hydrodynamic simulations have demonstrated the importance of hydrodynamic motions in the convective boundary and radiative regions of stars to transport of energy, momentum, and composition. The impact of these processes increases with stellar mass. Stellar models that approximate this physics have been tested on several classes of observational problems. In this Letter, we examine the implications of the improved treatment for supernova progenitors. The improved models predict substantially different interior structures. We present presupernova conditions and simple explosion calculations from stellar models with and without the improved mixing treatment at 23 M☉. The results differ substantially.
Accessible Handheld And Desktop Text Entry For People With Motor Impairments

In recent years there has been much effort to make desktop computers more accessible to people with motor impairments. However, computing today increasingly takes place off the desktop on small handheld devices such as personal digital assistants (PDAs) and mobile phones. But little attention has been paid to making these devices accessible, particularly to those who have motor impairments such as tremor or spasm. To address this, we have developed a new text entry method for PDAs and mobile phones called EdgeWrite , which provides physical stability to people entering text on a Palm PDA. Our studies show that EdgeWrite is significantly more accurate than the built-in method Graffiti for people both with and without motor impairments. We have also adapted the EdgeWrite design to common input devices for desktop computer access, thus lowering the cost for adequate computer access in the workplace.
Study of Staphylococcus Aureus Adhesion on a Novel Nanostructured Surface by Chemiluminometry

In recent years the progress in the field of nanotechnologies has offered new possibilities to control the superficial features of implant materials down to a nanoscale level. Several studies have therefore tried to explore the effects of nanostructured biomaterial surfaces on the behavior of eukaryotic cells. However, nanotopography could exert an influence also on the behavior of prokaryotic cells, with relevant implications concerning the susceptibility of implant surfaces to infection. Aim of this study was to examine the behavior of Staphylococcus aureus on polyethylene terephthalate (PET) surfaces either cylindrically nanostructured (PET-N) or flat ion-etched (PET-F), and on tissue culture-grade polystyrene (PS). Microbial adherence was assessed by chemiluminometry under 4 different conditions: (a) bacteria suspended in MEM medium, (b) bacteria in MEM supplemented with 10% fetal bovine serum (FBS), (c) test surfaces preconditioned in FBS, and (d) post-exposure of colonised surfaces to serum-supplemented MEM. Under all circumstances, PET-F and PET-N specimens showed identical bacterial adhesion properties. In the absence of serum, all 3 test materials showed a very high adhesivity to microbial cells and both PET surfaces exhibited greater adhesion than PS. On the contrary, the presence of 10% serum in solution significantly affected cell behavior: the number of microbial cells on all surfaces was drastically reduced, and the adhesion properties of PET surfaces with respect to PS were reversed, with PET being less adhesive. Overall, the specific cylindrical nanostructures created on PET did not significantly influence microbial behavior. Ongoing studies are verifying whether other nanotopographies with different geometry could have more substantial effects.
Numerical anlaysis of human exposure to electromagnetic fields from wireless power transfer systems

In this paper, we investigate a human exposure to wireless power transfer system operating at 1.8 MHz and 6.78 MHz. A method comprising a finite element method and a finite difference time domain is used for the numerical analysis of human exposure. The SARs of the Korean human body model are evaluated in relation to the different positions and orientation of wireless power transfer system. We discuss the numerical computation results along with the Non-Ionizing Radiation Protection (ICNIRP) guideline.
Improving strength and power in trained athletes with 3 weeks of occlusion training.

PURPOSE To examine the effects of moderate-load exercise with and without blood-flow restriction (BFR) on strength, power, and repeated-sprint ability, along with acute and chronic salivary hormonal parameters. METHODS Twenty male semiprofessional rugby union athletes were randomized to a lower-body BFR intervention (an occlusion cuff inflated to 180 mmHg worn intermittently on the proximal thighs) or a control intervention that trained without occlusion in a crossover design. Experimental sessions were performed 3 times a week for 3 wk with 5 sets of 5 repetitions of bench press, leg squat, and pull-ups performed at 70% of 1-repetition maximum. RESULTS Greater improvements were observed (occlusion training vs control) in bench press (5.4 ± 2.6 vs 3.3 ± 1.4 kg), squat (7.8 ± 2.1 vs 4.3 ± 1.4 kg), maximum sprint time (-0.03 ± 0.03 vs -0.01 ± 0.02 s), and leg power (168 ± 105 vs 68 ± 50 W). Greater exercise-induced salivary testosterone (ES 0.84-0.61) and cortisol responses (ES 0.65-0.20) were observed after the occlusion intervention sessions compared with the nonoccluded controls; however, the acute cortisol increases were attenuated across the training block. CONCLUSIONS Occlusion training can potentially improve the rate of strength-training gains and fatigue resistance in trained athletes, possibly allowing greater gains from lower loading that could be of benefit during high training loads, in competitive seasons, or in a rehabilitative setting. The clear improvement in bench-press strength resulting from lower-body occlusion suggests a systemic effect of BFR training.
Modeling waves and surf

Although modeling natural phenomena is recognized as one of the greatest challenges of computer graphics, relatively little time has been spent on modeling ocean waves. The model presented in this paper is suitable for the rendering and animation of waves approaching and breaking on a sloping beach. Waveforms consist of a phase function which correctly produces wave refraction and other depth effects, and a wave profile which changes according to wave steepness and water depth. Particle systems are used to model the spray produced by wave breaking and collisions with obstacles. A scanline algorithm for displaying the wave surface is presented, along with a method of integrating separately rendered particle systems with other surfaces. Hidden surface removal for both waves and particles is done using a novel variation of the A-buffer technique. Methods of implementing the model are presented and compared with previous rendering techniques.
Bankruptcy prediction using SVM models with a new approach to combine features selection and parameter optimisation

Due to the economic significance of bankruptcy prediction of companies for financial institutions, investors and governments, many quantitative methods have been used to develop effective prediction models. Support vector machine (SVM), a powerful classification method, has been used for this task; however, the performance of SVM is sensitive to model form, parameter setting and features selection. In this study, a new approach based on direct search and features ranking technology is proposed to optimise features selection and parameter setting for 1-norm and least-squares SVM models for bankruptcy prediction. This approach is also compared to the SVM models with parameter optimisation and features selection by the popular genetic algorithm technique. The experimental results on a data set with 2010 instances show that the proposed models are good alternatives for bankruptcy prediction.
Identifying Stable Reference Genes for qRT-PCR Normalisation in Gene Expression Studies of Narrow-Leafed Lupin (Lupinus angustifolius L.)

Quantitative Reverse Transcription PCR (qRT-PCR) is currently one of the most popular, high-throughput and sensitive technologies available for quantifying gene expression. Its accurate application depends heavily upon normalisation of gene-of-interest data with reference genes that are uniformly expressed under experimental conditions. The aim of this study was to provide the first validation of reference genes for Lupinus angustifolius (narrow-leafed lupin, a significant grain legume crop) using a selection of seven genes previously trialed as reference genes for the model legume, Medicago truncatula. In a preliminary evaluation, the seven candidate reference genes were assessed on the basis of primer specificity for their respective targeted region, PCR amplification efficiency, and ability to discriminate between cDNA and gDNA. Following this assessment, expression of the three most promising candidates [Ubiquitin C (UBC), Helicase (HEL), and Polypyrimidine tract-binding protein (PTB)] was evaluated using the NormFinder and RefFinder statistical algorithms in two narrow-leafed lupin lines, both with and without vernalisation treatment, and across seven organ types (cotyledons, stem, leaves, shoot apical meristem, flowers, pods and roots) encompassing three developmental stages. UBC was consistently identified as the most stable candidate and has sufficiently uniform expression that it may be used as a sole reference gene under the experimental conditions tested here. However, as organ type and developmental stage were associated with greater variability in relative expression, it is recommended using UBC and HEL as a pair to achieve optimal normalisation. These results highlight the importance of rigorously assessing candidate reference genes for each species across a diverse range of organs and developmental stages. With emerging technologies, such as RNAseq, and the completion of valuable transcriptome data sets, it is possible that other potentially more suitable reference genes will be identified for this species in future.
A Path Analytic Study: Effect of Affective Characteristics on Learning Outcomes *

Primary purpose of this study is to examine affective characteristics affecting the student’s achievement and influences of the relationships between these characteristics on the achievement with path analysis. With this purpose, students’ self efficacy perceptions and their attitudes towards physics and computer were taken in account as affective characteristics. Each of these characteristics is independent variables and their effects examining on the basis of learning approaches of Computer Aided Cooperative Learning (CACL) and Computer Aided 7E model (CA7E). As a result of these examinations, conducted with the path analysis; it has been determined that the affective characteristics such as attitudes towards the computer and physics courses and selfefficacy perceptions are not an effective factor on the students’ achievements considering both in the concept and physics course. Setting out from these findings, it has been concluded that the self-efficacy perception and attitude towards the physics course may not have that much big of an influence on achievement as it has been stated in literature.
Modeling a Cortical Auxin Maximum for Nodulation: Different Signatures of Potential Strategies

Lateral organ formation from plant roots typically requires the de novo creation of a meristem, initiated at the location of a localized auxin maximum. Legume roots can form both root nodules and lateral roots. From the basic principles of auxin transport and metabolism only a few mechanisms can be inferred for increasing the local auxin concentration: increased influx, decreased efflux, and (increased) local production. Using computer simulations we investigate the different spatio-temporal patterns resulting from each of these mechanisms in the context of a root model of a generalized legume. We apply all mechanisms to the same group of preselected cells, dubbed the controlled area. We find that each mechanism leaves its own characteristic signature. Local production by itself can not create a strong auxin maximum. An increase of influx, as is observed in lateral root formation, can result in an auxin maximum that is spatially more confined than the controlled area. A decrease of efflux on the other hand leads to a broad maximum, which is more similar to what is observed for nodule primordia. With our prime interest in nodulation, we further investigate the dynamics following a decrease of efflux. We find that with a homogeneous change in the whole cortex, the first auxin accumulation is observed in the inner cortex. The steady state lateral location of this efflux reduced auxin maximum can be shifted by slight changes in the ratio of central to peripheral efflux carriers. We discuss the implications of this finding in the context of determinate and indeterminate nodules, which originate from different cortical positions. The patterns we have found are robust under disruption of the (artificial) tissue layout. The same patterns are therefore likely to occur in many other contexts.
