Influence of Plantar Sensation Decrease on Lower Limbs for Human Gait under Uneven Surface
Shinichiro SUZUKI,Kentaro SEKIGUCHI,Hiroshi TAKEMURA,Hiroshi MIZOGUCHI 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
This paper describes the walking analysis that pays attention to the relation between plantar sensation and walking. Falling accidents during walking is one of serious problem, and most of them occur under irregular terrain. Thus, the authors made measurement by using motion capture system under such environment. In this measurement, we made uneven surface as one of irregular terrain and used it for the measurement. Also, we decreased plantar sensation of subjects by ice exposure, and compared with normal walking. As a result, significant differences of both motions of lower limbs were found. It is thought that plantar sensation plays an important role in waking with uneven surface.
EXTENDING THE UNPLANNED PURCHASE TYPOLOGY AND SHOPPER SENTIMENT TOWARD UNPLANNED PURCHASE

This study extends the previously classified typology of unplanned purchases to accommodate the increase in online purchases. We also measured the impact of unplanned purchases on shoppers from an emotional perspective. As a result, new types of unplanned purchases, such as novelty, recall, salience, reference price, risk aversion, and embodied cognition, were derived. Furthermore, among unplanned purchases, salience purchases were found to significantly increase shoppers' interest. This result indicate that the importance of marketing strategies that take salience into account for manufacturers and retailers.

Frequent occurrences of green tides caused by Ulva species (Ulvales, Ulvophyceae) associated with eutrophication along enclosed coasts are currently causing environmental problems in coastal ecosystems. In addition, increasing intercontinental introductions of coastal marine organisms, including Ulva, are also a serious issue. However, due to the considerable morphological plasticity of this genus, the taxonomy of Ulva species based on morphological studies is problematic. Therefore, in order to elucidate the species diversity and seasonal changes of the dominant Ulva species in Mikawa Bay, central Honshu, Japan, we made seasonal collections of Ulva species at seven localities, and identified the dominant species using the ITS2 rDNA region sequences. We identified the following nine taxa as common Ulva species in the area: 1) Ulva pertusa Kjellman; 2) U. ohnoi Hiraoka et Shimada; 3) U. linza L.; 4) U. californica Wille; 5) U. flexuosa Wulfen; 6) U. fasciata Delile; 7) U. compressa L.; 8) U. armoricana Dion et al.; 9) U. scandinavica Bliding. Among the species, U. pertusa was most common and dominant from spring to summer, and U. ohnoi from autumn to winter. Ulva californica and U. scandinavica have not been reported before from Japan.
Polymer structure and properties in micro- and nanomolding process

Injection molding of thin-wall parts with micro/nano-scale patterns using various polymers was performed to clarify the processability and surface replication of molded parts. Effects of process conditions on processability, higher-order structure and surface properties of molded parts were evaluated. The optical anisotropy in the vicinity of the gate became higher than at any other positions. The height replication ratio of surface patterns increased with increasing injection speed, holding pressure, injection temperature and mold temperature. In the case of nanomolding, negative birefringence toward the flow direction appeared higher than at the skin–shear region from the observation of skin–shear and core structure inside molded parts. Thus, the molecular orientation axis was oriented along the thickness direction because of deformation during the demolding process. Thermal stability of nano-surface patterns was influenced by the size of surface features and internal higher-order structure.
