training of patient鈥檚 hand function. A common measure in these peg boards is a total time of performance execution assessed by a tester鈥檚 stopwatch. Introduction of electrical and automatic measurement technology to the apparatus, on the other hand, has been delayed. The present work introduces the development of a pegboard with an electric sensor to detect moments of individual peg鈥檚 insertion and removal. The work also gives fundamental data obtained from a group of healthy young individuals who performed peg transfer tasks using the pegboard developed. Through trails and errors in pilot tests, two 10-hole peg-board boxes installed with a small photo-reflector and a DC amplifier at the bottom of each hole were designed and built by the present authors. The amplified electric analogue signals from the 20 reflectors were automatically digitized at 500 Hz per channel, and stored in a PC. The boxes were set on a test table at different distances (25, 50, 75, and 125 mm) in parallel to examine the effect of hole-to-hole distance. Fifty healthy young volunteers (25 in each gender) as subjects of the study performed successive fast 80 time peg transfers at each distance using their dominant and non-dominant hands. The data gathered showed a clear-cut light interruption/continuation moment by the pegs, allowing accurately (no tester鈥檚 error involved) and precisely (an order of milliseconds) to determine the pull out and insertion times of each peg. This further permitted computation of individual peg movement duration (PMD: from peg-lift-off to insertion) apart from hand reaching duration (HRD: from peg insertion to lift-off). An accidental drop of a peg led to an exceptionally long ( < mean + 3 SD) PMD, which was readily detected from an examination of data distribution. The PMD data were commonly right-skewed, suggesting that the median can be a better estimate of individual PMD than the mean. Repeated measures ANOVA using the median values revealed significant hole-to-hole distance, and hand dominance effects, suggesting that these need to be fixed in the accurate evaluation of PMD. The gender effect was non-significant. Performance consistency was also evaluated by the use of quartile variation coefficient values, which revealed no gender, hole-to-hole, and hand dominance effects. The measurement reliability was further examined using interclass correlation obtained from 14 subjects who performed the 25 and 125 mm hole distance tasks at two 7-10 days separate test sessions. Inter-class correlation values between the two tests showed fair reliability for PMD (0.65-0.75), and for HRD (0.77-0.94). We concluded that a sensor peg board developed in the present study could provide accurate (excluding tester鈥檚 errors), and precise (at a millisecond rate) time information of peg movement separated from that used for hand movement. It could also easily detect and automatically exclude erroneous execution data from his/her standard data. These would lead to a better evaluation of hand dexterity function compared to the widely used conventional used peg boards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hand" title="hand">hand</a>, <a href="https://publications.waset.org/abstracts/search?q=dexterity%20test" title=" dexterity test"> dexterity test</a>, <a href="https://publications.waset.org/abstracts/search?q=peg%20movement%20time" title=" peg movement time"> peg movement time</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20consistency" title=" performance consistency"> performance consistency</a> </p> <a href="https://publications.waset.org/abstracts/84616/a-peg-board-with-photo-reflectors-to-detect-peg-insertion-and-pull-out-moments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84616.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Preparation of CuAlO2 Thin Films on Si or Sapphire Substrate by Sol-Gel Method Using Metal Acetate or Nitrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Ehara">Takashi Ehara</a>, <a href="https://publications.waset.org/abstracts/search?q=Takayoshi%20Nakanishi"> Takayoshi Nakanishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kohei%20Sasaki"> Kohei Sasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Abe"> Marina Abe</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Abe"> Hiroshi Abe</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiyoaki%20Abe"> Kiyoaki Abe</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryo%20Iizaka"> Ryo Iizaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Takuya%20Sato"> Takuya Sato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CuAlO<sub>2</sub> thin films are prepared on Si or sapphire substrate by sol-gel method using two kinds of sols.

In contrast, in the case of the films prepared using nitrate on Si substrate, XRD peaks of CuAlO<sub>2</sub> have been observed only at the annealing temperature of 800-850 ºC. At annealing temperature of 850ºC, peaks of other species have been observed beside the CuAlO<sub>2</sub> peaks, then, the CuAlO<sub>2</sub> peaks disappeared at annealing temperature of 900 °C with increasing in intensity of the other peaks. Intensity of the other peaks decreased at annealing temperature of 950 ºC with appearance of broad SiO<sub>2</sub> peak.

As countermeasures in the field of road engineering, cool pavements such as water retaining pavements and solar radiation reflective pavements have been developed to reduce the surface temperature of asphalt pavements in the hot summer climate in Japan. The authors have studied on the water retaining pavements with cement–based grouting materials. The cement–based grouting materials consist of cement, ceramic waste powder, and natural zeolite. The ceramic waste powder is collected through the recycling process of electric porcelain insulators. In this study, mixing ratio between the ceramic waste powder and the natural zeolite and a type of cement for the cement–based grouting materials is investigated to measure the surface temperature of asphalt pavements in the outdoor. All of the developed cement–based grouting materials were confirmed to effectively reduce the surface temperature of the asphalt pavements. Especially, the cement–based grouting material using the ultra–rapid hardening cement with the mixing ratio of 0.7:0.3 between the ceramic waste powder and the natural zeolite reduced mostly the surface temperature by 20 °C and more. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20waste%20powder" title="ceramic waste powder">ceramic waste powder</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20zeolite" title=" natural zeolite"> natural zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20surface%20temperature" title=" road surface temperature"> road surface temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20retaining%20pavements" title=" water retaining pavements"> water retaining pavements</a> </p> <a href="https://publications.waset.org/abstracts/45874/effect-on-surface-temperature-reduction-of-asphalt-pavements-with-cement-based-materials-containing-ceramic-waste-powder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Surface Temperature of Asphalt Pavements with Colored Cement-Based Grouting Materials Containing Ceramic Waste Powder and Zeolite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Higashiyama">H.

Cool pavements reduce the surface temperature compared to conventional asphalt pavements in the hot summer climate and improve the thermal environment in the urban area. The authors have studied cement–based grouting materials poured into voids in porous asphalt pavements to reduce the road surface temperature. For the cement–based grouting material, cement, ceramic waste powder, and natural zeolite were used. This cement–based grouting material developed reduced the road surface temperature by 20 °C or more in the hot summer season. Considering the urban landscape, this study investigates the effect of surface temperature reduction of colored cement–based grouting materials containing pigments poured into voids in porous asphalt pavements by measuring the surface temperature of asphalt pavements outdoors. The yellow color performed the same as the original cement–based grouting material containing no pigment and was thermally better performance than the other color. However, all the tested cement–based grouting materials performed well for reducing the surface temperature and for creating the urban landscape. <p class="card-text"><strong>Keywords:</strong> <a
