The purpose of this study is to analyze the body type of children's, especially torso, and to provide the fundamental data for children's clothing construction which can reflect the characteristics of their bodies. The subjects for photographic measurements are 308 elementary school children aged from 6 to 8 living in Seoul and urban area. Anthropometric measurements were performed indirectly from the pictures of subjects. The data were analyzed statistically using SPSSWIN. The results obtained from this study are as follows: 1. Through one-way ANOVA, items for heights, breaths, weight reveals the significant differences according to ages and genders. 2. Through Pearson correlation, it turns out that there are high correlation between any items of heights, but there is no correlation for item of shoulder inclination with any other items. 3. Through factor analysis of principal component model, six factors were extracted which covers 83.6% of the whole information. The first factor represents the items of heights which relates with linearity. The second factor describes the items of breaths, depths, and weight in relation with laterality. The third factor were gathered with depths of front and back in relation with posture of side, which proves as important one to characterize the children's torso. The other factors represents the items of posture of neck, depths in neck, shoulder inclination, respectively. 4. Through one-way ANOVA in factor by group, and Scheffe multi comparison test for each group, the factor 1 that is related with linearity reveals the significant differences according to ages and genders.

The purpose of this study was to identify the relationship between lifestyles and clothing benefits pursuit. A questionnaire was developed to measure lifestyle and clothing benefits sought. The questionnaire was distributed and collected from 131 college female students in Tokyo. The data was analyzed by percentage, frequency, mean, standard deviation, factor analysis, reliability test, MANOVA and ANOVA by SPSS package. The lifestyles of the respondents were classified into five types such as recreational-oriented, fashion-oriented, progressive-oriented, intentional purchasing, and economics-oriented type. And clothing benefits pursuit was classified into five types such as individuality-pursuit, brand-pursuit, convenience-pursuit, fashion -pursuit, and coordination/figure flaws compensation-pursuit. The result of this study were as follows; 1) All of three lifestyle groups of appearance-oriented type, fashion-oriented type, intentional purchasing type had an inclination for individuality-pursuit, brand-pursuit, fashion-pursuit, and not an inclination for convenience-pursuit. 2) The higher the fashion-oriented and intentional purchasing, and the lower the progressive-oriented and economics-oriented were, the higher was individuality-pursuit. 3) The higher progressive-oriented and the lower recreational-oriented were, the higher convenience-pursuit was. 4) The brand-pursuit, convenience-pursuit, and fashion-pursuit were not shown to have the significant differences according to intentional purchasing group.

The purpose of this study is to analyze the hydraulic characteristics of the ice-harbor fishway by considering its geometrical form and utilize such analysis results as the foundational database to be used when establishing fishways in the future. first of all, the study realizes the same form as an ice-harbor fishway that is currently implemented via a FLOW-3D model and estimated the parameters that were optimal to the numerical mock test. Then, this study analyzed the level of sensitivity of the flow conditions which fluctuated due to the changes in geometrical changes by adjusting the inclination and pocket spacing by using the estimated optimal parameters. As a result, the study arrived at the following conclusions. The vortical velocity increased and had a significant effect on the inclination of the fishway. Furthermore, as the velocity within the vorticity increased due to the narrowed vortical area, it was determined that further studies on vorticities or the determination of the design method for the decrease in vortical velocity were imperative.

In the last few years, many structural monitoring studies have been performed using different techniques to measure structures of different scales such as buildings, dams or bridges. One of the mostly used tools are GPS instruments, which have been utilized in various combinations with accelerometers and some other conventional sensors. In the current study, observation series were recorded for 8 hours with GPS receivers (NovAtel) and Inclination Measurement Sensors mounted on a television tower in Istanbul, Turkey. Each series of observations collected from two different sensors were transformed into a single coordinate system (Local Topocentric Coordinates System). The positional changes of the tower were calculated from the GPS and the inclination data. These changes were plotted in two dimensions (2D) on the same graphic. Thus, the possibility of comparison and analysis were found using the data from both the GPS and the Inclinometer complement each other, in the real test area. The positional changes of the tower were modeled for further examination. As a result, the movement of the tower within an area of $1{\times}1cm^2$ was observed. Based on the results, it can be concluded that inclinometers can be used for monitoring the structural behavior of the tower.

Augmentation of CHF by ultrasonic vibration in water pool is experimentally investigated under pool boiling condition. The experiments are carried out using copper coated plates and distilled water. Measurements of CHF on flat plate heated surface were made with and without ultrasonic wave and with variations in inclined angle of the surface and water subcooling. Experimental apparatus consists of a bath, power supply, test section, ultrasonic generator, and data acquisition system. The measurements show that ultrasonic wave enhances CHF and its extent is dependent upon inclination angle as well as water subcooling. The rate of increase in CHF increases with an increase in water subcooling while it decreases with an increase in inclination angle. Visual observation shows that the cause of CHF augmentation is closely related with the dynamic behavior of bubble generation and departure in acoustic field.

The primary objective of this paper was to study the seepage and the failure behavior of unreinforced and reinforced embankment, respectively. Experimental study was conducted to examine the infiltration characteristics. The embankment infiltration tests were conducted with water level condition(h=15cm, 25cm, 35cm), slope inclination(1:1.5, 1:2.0), and the rising velocity(1.25cm/min, 2.5cm/min), respectively. From the model test results, as the slope inclination is decreased, the rising velocity of seepage line increased with both reinforced and unreinforced embankment. With the unreinforced embankment, the rising velocity of water level was faster and the failure circle is lager than those of reinforced ones. And the reinforced embankment with geotextile was safer against seepage force than that of the unreinforced embankment.

Purpose: This study examined the effects of applying the Pilates reformer exercise to 17 adult women on the alignment of the standing posture. Methods: The subjects performed a Pilates reformer exercise for 60 minutes a day, three times a week, for a total of eight weeks. The Pilates reformer exercise consisted of five types: 1) lower and lift, 2) hundred, 3) plow, 4) airplane, and 5) twist. The standing posture alignment in the sagittal and frontal planes was measured using exbody 9100MOMI musculoskeletal analysis equipment. Results: A comparison of before and after the exercise using paired t-test revealed a significant decrease in the difference between the horizontal inclination and the vertical height that approached zero after the intervention in the frontal plane of anterior and posterior standing postures (p<0.05), and the lateral standing posture in the sagittal plane. In addition, the difference between the horizontal inclination and the vertical height decreased and approached zero after the intervention (p<0.05). Conclusion: The Pilates reformer exercise had a positive effect on the alignment of the standing posture.

This paper describes the posture stabilization control of a bipedal transformer robot being developed for military use. An inverted pendulum model with a rectangular that considers the robot's inertia is proposed, and a posture stabilization moment that can maintain the body tilt angle is derived by applying disturbance observer and state feedback control. In addition, vertical force and posture stabilization moments that can maintain the body height and balance are derived through QP optimization to obtain the necessary torques and vertical force for each foot. The roll and pitch angles of the IMU sensor attached to the robot's feet are reflected in the ankle joint to enable flexible adaptation to changes in ground inclination. Finally, the effectiveness of the proposed algorithm in posture stabilization is verified by comparing and analyzing the difference in body tilt angle due to disturbances and ground inclination changes with and without algorithm application, using Gazebo dynamic simulation and a down-scale test platform.

This is a study on rectangular-shaped passive row piles in inclined sand-ground by model tests. The experiment controlled the angle of inclination of ground and induced the ground destruction. We also measured the behavior of row piles, by adjusting the shape, position and spacing of piles. As a result, we confirmed the earth pressure, the lateral resistance, and the effect of depressing on the ground variation working on passive pile. The effect of B-type pile of which the front width is wide is bigger than that of H-type pile of which the side width is wide. We can find out the failure angle of slope, the shared force of pile and soil by using the lateral resistance graph based on slope angle.
