The Effectiveness of Disease and Case Management for People with Diabetes A Systematic Review

Cost-effectiveness of intensive insulin therapy for type 2 diabetes: a 10-year follow-up of the Kumamoto study.

Objective. Health-related quality of life plays an important role in assessing the effectiveness of health care. The EuroQol is a generic instrument for describing and valuing health-related quality of life. To elicit health state descriptions and their preferences among the general public in Japan and compare them with cross-national data, a feasibility study for applying the EuroQol to the general public in Japan was carried out.
Subjects and methods. The subjects were 120 people aged 40s-60s randomly selected in a suburban area at Aichi Prefecture in Japan. In assessing health states and their preferences, the EuroQol valuation instrument (version 12, 1991) translated into Japanese was used. The questionnaires were distributed and collected by public health nurses. The valid responses (rate) were 89 (74%).
Results. The mean scores (raw scores) using the visual analogue scale (VAS) for one’s own health was 89.2. No statistically significant difference in VAS scores was observed for both sex and age. The contribution ratio of own health status, sex and age was 0.326 (p<0.0001). The main independent variables were three dimensions of health status.Valuations for core health states varied from 96.3 (no problems in each health status) to 6.8 (dead). These VAS scores in Japan were correlated with those from other countries (p<0.001). A multivariate analysis indicated that bias from own health status on preference valuations for core health states was not observed.
Conclusion. The health states and their preferences among the general public in Japan were estimated by using the EuroQol. The results show the feasibility of evaluation for health states quantitatively. Moreover, this study suggested cross-national and cross-cultural applicability of the EuroQol.

Real-time video streaming over vehicular ad-hoc networks (VANETs) has been considered as a critical challenge for road safety applications. The purpose of this paper is to reduce the computation complexity of high efficiency video coding (HEVC) encoder for VANETs. Based on a novel spatiotemporal neighborhood set, firstly the coding tree unit depth decision algorithm is presented by controlling the depth search range. Secondly, a Bayesian classifier is used for the prediction unit decision for inter-prediction, and prior probability value is calculated by Gibbs Random Field model. Simulation results show that the overall algorithm can significantly reduce encoding time with a reasonably low loss in encoding efficiency. Compared to HEVC reference software HM16.0, the encoding time is reduced by up to 63.96%, while the Bjontegaard delta bit-rate is increased by only 0.76–0.80% on average. Moreover, the proposed HEVC encoder is low-complexity and hardware-friendly for video codecs that reside on mobile vehicles for VANETs.

Low-Complexity and Hardware-Friendly H.265/HEVC Encoder for Vehicular Ad-Hoc Networks.

Perceptual video coding (PVC) can provide a lower bitrate with the same visual quality compared with traditional H.265/high efficiency video coding (HEVC). In this work, a novel H.265/HEVC-compliant PVC framework is proposed based on the video saliency model. Firstly, both an effective and efficient spatiotemporal saliency model is used to generate a video saliency map. Secondly, a perceptual coding scheme is developed based on the saliency map. A saliency-based quantization control algorithm is proposed to reduce the bitrate. Finally, the simulation results demonstrate that the proposed perceptual coding scheme shows its superiority in objective and subjective tests, achieving up to a 9.46% bitrate reduction with negligible subjective and objective quality loss. The advantage of the proposed method is the high quality adapted for a high-definition video application.

Quality-Oriented Perceptual HEVC Based on the Spatiotemporal Saliency Detection Model.

In this paper, an improved low complexity algorithm for the scalable extension of the HEVC (SHVC) is proposed by using the information of rate-distortion cost (RD cost) of the coding unit at the co-located position in the base layer and the neighboring coding unit in the enhancement layer. The proposed algorithm in our previous work used an early determination of the depth decision by adaptively selecting an optimal threshold value on the basis of RD cost. However, the threshold value become a low accuracy value because RD cost and the coding unit depth in different resolutions depend on the quantization parameter. Therefore, the relationship of the quantization parameter in different resolutions is evaluated. Based on the evaluation results, an improved algorithm focused on the complexity reduction of the enhancement layer is proposed. The proposed algorithm is evaluated by the reference software of SHVC(SHM6.0). The simulation results show that the proposed algorithm can achieve over 48% computation complexity reduction comparing to the original SHVC algorithm.
