  • The purpose of this study is to identify which width of the base of support(BOS) is safer and more effective in lifting by comparing muscle activations and body sways when lifting objects under the width variation of the BOS. A total of fifteen healthy adults participated in this study. For the width variation of the BOS, the participants changed the width between their feet into three different types(10cm, 32cm, 45cm) and lifted a 10kg four times in each type after going up on a force plate. In order to measure body sways according to the width variation of the BOS, a motion analysis system was used. In addition, in order to measure the muscle activations of lower extremities, including the erector spinae, gluteus maximus, rectus femoris, and tibialis anterior, an electromyogram(EMG) analysis was employed. In addition, the Borg's scale was drawn by quantifying the subjective discomfort levels felt from each width of the BOS. In conclusion, no statistically significant differences according to the width variation of the BOS were observed(p=.295, .308)(p>.05). However, a statistically significant difference was exhibited between the Borg's scale, which indicates the discomfort levels from lifting performances, and the width variation of the BOS (p=$.000^*$).

  • In order to reflect emotion and sensibility of consumers to textile pattern design, the effect of design elements of block stripe pattern on sensitivity was investigated. The stimuli were manipulated with 4 design elements of value difference (3 levels), arrangement (2 levels), width (2 levels) and interval (3 levels). Among the 36 combinations, 27 stimuli, which showed independent sensibility results in the pretest, were adopted as final stimuli. Male and female university students (n=30) evaluated each sensibility subjectively using a questionnaire developed for this study. The effect of design elements on 12 sensibility dimensions drawn by factor analysis and the relationships between the physical quantities of each stimulus and the sensibilities were investigated. As the results of ANOVA for the effect of design elements on sensibility, there were more significant differences in sensibility in the orders of value difference, interval, width, and arrangement. The value difference showed the highest explanatory power. Looking at the sensibility differences according to the level of design elements, the narrower the width of the stripe, the more 'humble', 'clean', 'modern', 'simple', and 'comfortable', and the narrower the interval between stripes, the more 'impressive' and 'conservative' The smaller the value difference, the more 'luxurious', 'modern', 'humble', 'simple', 'soft', and 'clean'. Regression models to predict the 12 sensibilities showed higher values of goodness of fit except 'conservative', 'casual' and 'modern', which were all over 0.6. Based on these results, 2 design prototypes reflecting consumer's sensibility were presented.

  • Thirteen varieties of Tongil type and ten of Japonica type which were produced in Korea, in 1985, were campa red in namely, width, thickness, length and weight of rice grains. Thousand-grain weight of paddy, brown rice and milled rice were not significantly different between Tongil type and Japonica type, but difference of paddy-brown rice and brown rice-milled rice had significant (p<2,859** and 4.316***, respectively), and the ratio of difference of paddy-brown rice was higher Tongil type than Japonica type. Width, thickness and length of paddy, brown rice and milled rice was significant (width : p<5.189***, 5.289** and 5.466***, thickness: p<3.371** 4.074*** and 5.988***, length: p<3.016**, 4.419*** and 5.492*** in paddy, brown rice and milled rice, respectively) between the Tongil type and Japonica type, and then the width and thickness of Japonica type were thicker than Tongil type, but length of Japonica type was shorter than Tongil type width/thickness ratio of paddy wes significant (p<2.396*) between the Tongil type and Japonica type, but its brown rice and milled rice was not. And length/width and length/ thickness ratio of paddy, brown rice and milled rice were significant (length/width : p<5.525***, 5.495*** and 5.863***, length/thickness: p<4.734***, 6,863*** and 8.425*** in paddy, brown rice and milled rice) between the Tongil type and Japonica type, and then its ratio were higher Tongil type than Japonica type.

  • A three stage sampling procedure designed to estimate the difference betweentwo normal means is proposed and evaluated within a unified decision-theoretic framework. Both point and fixed-width confidence interval estimation are combined in a single decision rule to make full use of the available data. Adjustments to previous solutions focusing on only one of the latter objectives are indicated. The sensitivity of the confidence interval for detecting shifts in true mean difference is also investigated Numerical and simulation studies are presented to supplement the theoretical results.

  • Two edge detection methods are devised and tested. First one makes use of mean-difference between two connected regions after bimodal thresholding within a local window. It appears experimentally to provide reduced edge width maintaining good connectivity. It seems due to the use of the threshold obtained from a larger neighborhood. Second one uses additionally the gradient information to detect approximate zero crossing points of second directional derivative. This provides edges thinned nearly to one pixel width.

  • In this experiments, the fracture loads were measured and analysed by using of Instron universal testing machine (Model 1132). With 80 upper and lower deciduous molars that were free of dental caries. Isthmus of teeth were prepared to 1/3 and 1/4 of intercuspal width, and internal line angles with round and sharp shape, and then amalgam restoration were performed. The results of this study were as follows; 1. Resistance to fracture loads were greater with isthmus of 1/3 intercuspal width than of 1/4 intercuspal width, especially, statistically significant difference on upper and lower second deciduous molars. 2. Resistance to fracture loads were greater with rounded internal line angle than sharp internal line angle. The above results were as follows, the fracture loads had greater resistance on isthmus of 1/3 intercuspal width, and rounded internal line angle, but normal physiological occlusal forces could permit isthmus of 1/4 intercuspal width and rounded internal line angle.

  • Peierls instability and spin ordering of zigzag graphene nanoribbons (GNR) created on a fully hydrogenated graphene (graphane) are investigated as a function of their width using first-principles density-functional calculations within the generalized-gradient approximation. For the width containing a single zigzag C chain (N=1), we find the presence of a Peierls instability with a bond alternated structure. However, for width greater than N=1, the Peierls distortion is weakened or disappears because of the incommensurate feature of Fermi surface nesting due to the interaction of C chains. Instead, there exists the antiferromagnetic (AFM) spin ordering in which the edge states are ferromagnetically ordered but the two ferromagnetic (FM) edges are antiferromagnetically coupled with each other, showing that electron-lattice coupling and spin ordering in GNR are delicately competing at an extremely thin width of N=2. It is found that, as the width of GNR increases, the energy gain arising from spin ordering is enhanced, but the energy difference between the AFM and FM (where two edge states are ferromagnetically coupled with each other) orderings decreases.

  • In this paper spacing and width of flexural cracks in reinforced concrete beams are determined using two-dimensional finite element analysis. At early loading stages on the beam the primary crack spacing is based on the slip length, which is the development length required to resist the steel stress increment that occurs at a cracked section on the formation of the first flexural crack. A semi-empirical formula is presented in this paper for the determination of the slip length for a given beam. At higher load levels, the crack spacing is based on critical crack spacing, which is defined as the particular crack spacing that would produce a concrete tensile stress equal to the flexural strength of concrete. The resulting crack width is calculated as the relative difference in extensions of steel reinforcement and adjacent concrete evaluated at the cracked section. Finally a comparative study is undertaken, which indicates that the spacing and width of cracks calculated by this method agree well with values measured by other investigators.
