The purpose of this study was to determine the effects of well-rounded exercise program (WREP) on cardiorespiratory fitness, muscular strength, flexibility, body composition, and serum lipid concentration in a group of older outpatients. WREP was composed of programmed aerobic/anaerobic accommodating circuit exercise (PACE) and flexibility exercises Twenty-two volunteers (69.6±3.2yr) were used as subjects All participants engaged in a supervised exercise program (50min/day and 3 days/week) for 12 weeks After 12 weeks of training, there was a significant increase in V0_2 corresponding to lactate threshold (13.4%) but peak VO_2 did not change. There were significant increases for knee extension (17.1%) and flexion (12.3%), chest pull (10.9%), low back flexion (26.6%), and shoulder press (14.6%) after training. Side stepping agility (13%), trunk flexion (129%) and trunk extension (19%) were also significantly improved. There were significant decreases in percent of body fat (-8.3%), total cholesterol (-7.1%) and low-density hpoprotein cholesterol (-9.7%) Blood pressure also decreased in SBP (-1OmmHg) and DBP (-5mmHg) The decline in SBP was significant in thirteen hypertensive patients (-14mmHg) compared to non-hypertensive patients (-5mmHg) These results indicate that WREP elicits significant improvement of overall fitness in older outpatients (Jpn J Phys Fitness Sports Med 2003, 52 : 513~524)

In ultrasound systems, there is a trade-off between image quality and the number of transducers (elements) placed in the array probe, and to achieve a high resolution, the array probe must be created with additional elements. In 3D/4D echo, a significant number of elements are required compared to 2D echo, because imaging is performed using a two-dimensional array probe. As a result, 3D/4D echo inevitably has the problem of increasing equipment costs. To solve this problem, it is necessary to develop a method to reconstruct images with higher resolution using fewer elements than conventional imaging methods. The L1-norm minimization method has attracted much attention in recent years because of its ability to reconstruct high-resolution images even from incomplete data. In this study, we investigated whether high quality images can be reconstructed by minimizing the L1 norm for an object with an orientation, height, and depth of the imaging area (3D object). We also used image quality evaluation methods (MSE: Mean Squared Error, PSNR: Peak Signal to Noise Ratio, and SSIM: Structural SIMilarity) to quantitatively evaluate the obtained images. The results confirmed that L1-norm minimization is capable of reconstructing high-quality images with high evaluation values in all image quality evaluation methods compared to conventional methods.
