The purpose of this study is to analyze the relationship among subjective textures, sensibilities and objective handle of knit fabrics and to provide useful information in planning and designing knit fabrics. We made 20 plain knit fabrics, as specimens, with a combination of 5 kinds of wool/rayon fiber contents and 4 kinds of stitch loop length. For the subjective evaluation, we used 29 questions of subjective textures and sensibilities and employed statistical analysis tools such as factor, Pearson's correlation analysis. An objective handle was measured by Kawabata evaluation system and HV and THV was calculated by KN-402-KT and KN-301-winter. The analysis of a Pearson's correlation with objective properties and handles and structural properties of knit fabrics demonstrated a highly linear relationship. Especially, wool/rayon contents and WT of tensile properties and loop stitch length and G of shear properties showed a correlation coefficient over 0.9. But a relationship of objective properties and subjective textures and sensibilities was non-linear and a linear multi-regression analysis showed that a objective handle had a lower prediction power in the area of subjective textures and sensibilities.

Distribution of fracture system is an important factor to analyse instability of jointed rock slope. In the most case of rock slopes, joint distribution properties are related to potential, shape, size and locality of slope failure. The purpose of this paper is to present an application of fracture characterization related to rock slope failure. Fracture data used in this study are collected by scanline survey. Two aspects of fracture characterization for rock slope are handled in this study First, In order to determine the potential and shape of slope failure, trace length of joints is considered as the weighting factor about collected orientation data. Second, Relationship between trace length and spacing is analysed to estimate failure location and size. The distribution of fracture system is directly influenced on wedge failure. It is effective to analyse the orientation of fractures by using weighting factors associated with the trace length of fractures rather than to analyse only that of fractures. It gives a conclusion that the wedge failure occurred along the peak of fracture density(or intensity) cycles.

Length-weight relationships were estimated for 11 fish species caught in Baekya Island, Korea. Samples were caught in depths of <15 m by fish pots between November 2008 and July 2009. The sampling gear, fish pots, is a widely used as commercial fishing gear in shallow waters of the region. The most abundant families were Hexagrammidae (20.7%), Cottidae (18.5%), Tetraodontidae (14.8%) and Scorpaenidae (13.3%). Estimates for parameter b of the length-weight relationship ($W=aL^b$) ranged between 2.454 and 3.361.

This paper presents a finite element approach for determining the natural frequencies for planar inclined arches of various shapes vibrating in three-dimensional space. The profile of inclined arches, represented by undeformed centriodal axis of cross-section, is defined by the equation of plane curves expressed in the rectangular coordinates which are : circular, parabolic, sine, elliptic, and catenary shapes. In free vibration state, the arch is slightly displaced from its undeformed position. The linear relationship between curvature-torsion and axial strain is expressed in terms of the displacements in three-dimensional space. The finite element discretization along the span length is used rather than the total are length. Numerical results for arches of various shapes are given and they are in good agreement with those reported in literature. The natural frequency parameters and mode shapes are reported as functions of two nondimensional parameters: the span to cord length ratio (e) and the rise to cord length ratio (f).

Strengthening and repair of concrete structures using externally bonded fiber reinforced polymer (FRP) composite sheets has been popular around the world during the last two decades. However, premature failure due to debonding of the FRP is one of the important issues still to be resolved. Numerous research studies have dealt with the debonding problem in terms of Effective Bond Length (EBL), however, determination of this length has not yet been completely assessed. This paper summarizes previous works on the EBL and proposes a new relationship of the EBL with the FRP stiffness based on the existing experimental data collected in this study.

Length-weight relationships were estimated for 19 fish species in sargassum beds of Gamak Bay: Aulichthys japonicus, Pseudoblennius cottoides, Pseudoblennius percoides, Ditrema temmincki, Acanthogobius lactipes, Chaenogobius heptacanthus, Cryptocentrus filifer, Pterogobius elapoides, Pterogobius zonoleucus, Hyporhamphus sajori, Hexagrammos agrammus, Rudarius ercodes, Lateolabrax japonicus, Pholis crassispina, Pholis nebulosa, Scomber japonicus, Sebastes inermis, Ernogrammus hexagrammus, and Takifugu niphobles. Samples were caught by surrounding net at depths of <7 m between November 2007 and June 2008. The most abundant families were Gobiidae (26.3%), Cottidae (10.5%), and Pholididae (10.5%). Estimates for parameter b of the length-weight relationship (W=$aL^b$) ranged between 2.491 and 3.354.

Correlations between various morphological characteristics of Panax quinquefolium plants grown in Lytton, British Columbia, Canada were assessed for 1-through 4-year old plants. Root dry weight, the dependent variable, was found to be strongly related to leaf dry weight, leaf length and root length for 1-and 2-year old plants during the middle of the growing season. For 1- and 2-year old plants at the end of the growing season, root dry weight was found to be related to leaf dry weight, leaf length and stem dry weight. For 3 and 4-year old plants, root dry weight was found to be related to leaf dry weight, leaf length and stem dry weight. For 3- and 4-year old plants, root dry weight was found to be related to leaf dry weight. For practical considerations, this latter relationship provides a simple method for selecting superior plants from which seed can be harvested.

Because of the various length condition of carbon nanotube, it is very confined the application area of the single CNT tip. In this paper, it was proposed the cutting technique of single CNT tip and the relationship between the etched volume and the amount of the applied charge. It is possible to control the length of single CNT tip arbitrary using this technique. The etched volume and length in the single CNT tip can be predicted with the amount of the applied charge. It is very easy to make a single CNT tip with proper length using this technique and to make nanotweezer that was composed two single CNT tips.

This paper introduces a method of estimating the knee joint moment developed during MVC. By combining the Hill-type muscle model and analytic results on moment arm and musculotendon length change as a function of hip and knee joint angle, the knee joint moment at a specific knee joint angle during MVC is determined. Many differences between the estimated results and the experimental data are noted. It is believed that these differences originate from inaccurate information on the muscle-tendon parameters. The establishment of exact values for the subject's muscle parameters is almost impossible task. However, sensitivity analysis shows that the tendon slack length is the most critical parameter when applying the Hill-type muscle model. The effect of a change of this parameter on the muscle length force relationship is analyzed in detail.
