  • This study was to provide the fundamental data for the ease necessary to design clothes by investigating the variation of the upper body surface with the method of surgical tape. The subject were 8 young women in the standard somatotype. In the form of body surface according to arm movements, the shape of armscye circumference became gentle from the sunken form for the standing posture; scye depth became lower; lateral shoulder moved and rose toward the front center as the angle of arm movement became larger; scye depth is greatest in the standing. The items of horizontal ware largest in the standing posture except for front neck base circumference and front interscye breadth for side $90^{\circ}$ movement. In the items of vertical, while most of the front items increased but back ones generally decreased for all movement compared to the standing. After comparing differences in actual values between the form of body surface in the standing posture and the direct measurement, the following ease were suggested considering minimum measures to accommodate daily movements. Bust circumference/2 = 3cm; waist circumference/2 = 1.5cm; front interscye breadth/2 = 0.6cm; back interscye breadth/2 = 0.6cm; and underarm depth = 1.5cm

  • Effect of alloying element additions to Ag on thermal conductivity electrical conductivity and mechanical properties of sheath materials for BSCCO tapes has been characterized. The thermal conductivity at low temperature range(10~300K) of Ag alloys were evaluated by both direct and indirect measurement techniques and compared with each other. It was observed that thermal conductivity decreased with increasing the content of alloying elements such as Au, Pd and Mg. Thermal conductivity of pure Ag at 30 K was measured to be 994.0 W/m.K on the other hand the corresponding values of A $g_{0.9995}$/M $g_{0.0005}$, A $g_{0.974}$/A $u_{0.025}$/M $g_{0.001}$, A $g_{0.973}$/Au.0.025//M $g_{0.002}$, and A $g_{0.92}$/P $d_{0.06}$/M $g_{0.02}$ were 342.6, 62.1, 59.2, 28.9 W/m.K respectively indicating 3 to 30 times lower than that of pure Ag. In addition alloying element additions to Ag improved mechanical strength while reduced elongation probably due to the strengthening mechanisms by the presence of additive atoms.s.

  • Critical current$(I_c)$ degradation of High $T_c$ Superconducting(HTS) tapes and AC loss under mechanical load is one of the hottest issues in HTS development and application. Mechanical load reduces the critical current of superconducting wire, and the $I_c$ degradation affects the AC loss of the wire. We measured the $I_c$ degradation and AC loss under tension and bending of Bi-2223 tapes made by 'Powder-in-Tube' technique at 77K with self-field. Also, we have studied the frequency characteristics on self-field AC loss in multi-filamentary Bi-2223/Ag tape at 77K. The measurement results and discussions on the relationship between $I_c$ degradation and AC loss are presented.

  • Background: This study investigated the effect of erector spinae and quadratus lumbar kinesio taping and support surface conditions on abdominal muscle activity during plank exercise. Design: Within-Group design. Methods: A total of twenty-three healthy men and women participated in this study. Abdominal muscle (both external obliques and internal oblique muscle) contraction was analyzed through EMG measurement with the presence or absence of kinesio taping applied to the erector spinae muscle and quadratus lumborum muscle during plank exercise and the difference between the support surfaces (stable surface and unstable surface) as variables. Abdominal EMG was attached to the right external oblique, left external oblique, right internal oblique, and left internal oblique. Results: The results showed that Abdominal left and right external obliques and internal obliques showed significant increases in activity when kinesio taping was applied to the erector spinae and quadratus lumborum muscles and unstable ground (p<0.05). Conclusion: In this study, we confirmed that the activity of the abdominal muscles was significantly increased during the plank operation in the state where the kinesio tape was attached. In addition, it was confirmed that the activity of the abdominal muscles was significantly increased during the plank operation on the unstable surface. These results suggest that in the state of kinesio tape attached and instability, plank motion has a positive effect on abdominal muscle activity.

  • In this paper, AC losses of long wire Bi-2223 tapes with different twist pitch of superconducting core were fabricated, measured and analyzed. These samples produced by a powder-in-tube method are multi-filamentary tape with Ag matrix. Also, it's produced by non-twist. The critical current measurement was carried out under the environment in Liquid nitrogen and in zero field by 4-prob method. And the Magnetic measurement was carried out under the environment of applied time-varying transport current by transport method. From experiment, the susceptibility measurements were conducted while cooling in a magnetic field. Flux loss measurements were conducted as a function of ramping rate, frequency and field direction. The AC flux loss increases as the twist-pitch of the tapes decreased, in agreement with the Norris Equation. Neutron-diffraction measurements have been carried out investigate the crystal structure, magnetic structures, and magnetic phase transitions in Bi-2223([Bi, Pb]:Sr:Ca:Cu:O).

  • Noise and vibration performance plays an important role in the development of rotating components, such as engines, drivelines, transmission systems, compressors and pumps. The presence of torsional vibrations and other specific phenomena require the dynamic behaviour of systems and components to be designed accurately in order to avoid comfort and durability related problems. This paper provides an overview of the instrumentation and challenges related to torsional vibration testing. The accuracy and performance of five measurement techniques (high-speed incremental encoder, dual beam laser interferometer, zebra tape, zebra disc, direct pulse measurements with magnetic probe) is investigated by measurements on a Fiat Punto 1.4 liter engine. The potential sources of error are discussed to explain the inaccuracies of each technique.

  • This paper introduces the developed geometry PIG (Pipeline Inspection Gauge), one of several ILI (In-Line Inspection) tools, which provide a full picture of the pipeline from only single pass, and has compact size of the electronic device with not only low power consumption but also rapid response of sensors such as calipers, IMU and odometer. This tool is equipped with the several sensor systems. Caliper sensors measure the pipeline internal diameter, ovality and dent size and shape with high accuracy. The IMU (Inertial Measurement Unit) measures the precise trajectory of the PIG during its traverse of the pipeline. The IMU also provide three-dimensional coordination in space from measurement of inertial acceleration and angular rate. Three odometers mounted on the PIG body provide the distance moved along the line and instantaneous velocity during the PIG run. The datum measured by the sensor systems are stored in on-board solid state memory and magnetic tape devices. There is an electromagnetic transmitter at the back end of the tool, the transmitter enables the inspection operators to keep tracking the tool while it travels through the pipeline. An experiment was fulfilled in pull-rig facility and was adopted from Incheon LT (LNG Terminal) to Namdong GS (Governor Station) line, 13 km length.

  • To present a 6-piece baseball cap pattern with good wearing sensation and with good reflection of head shape, this study conducted direct measurement using martin's anthropometer and indirect measurement using surgical tape among women of 20 to 24 years old. For a crown, correlation analysis was carried out between direct measurements and surface shell measurements of each section on the head to set main items for prototype design, along with regression analysis to complete design formula; for a cap pattern, draping design was used on the finished crown to compete cap pattern design formula. The results showed that main measurement items to design a baseball cap included head circumstance and bitragion arc for a crown and the cephalic index for a cap. For the crown pattern reflecting the shape of the head, 6 pieces were designed with different sizes and types of front (F), side (S), and back (B) patterns; hemline was also designed diagonally and completed by reflecting the curve of the head.
