The concern for living a healthier and more active life has increased and the target market for the leisure-sportswear will broaden. This study suggests ideas and directions to develop horse-riding pants that consider fit satisfaction, demand performance and design requirements. A total of 203 riders were surveyed in Busan, Jeju, and Gwacheon horse racing tracks from November to December 2011 and from September to October 2012. Frequency analysis, ANOVA, t-test, and ${\chi}^2$-test were performed for the statistical analysis of the data using SPSS Win 21.0 program. The results of this study are as follows. The satisfaction of riding pants showed differences according to gender, riding career, BMI, age, and riding level. Females showed lower satisfaction of pant length than males. Riders with 1-4 years riding career showed more satisfaction of the front waist circumference. The group between 10 and 20 years more strongly preferred a rubber band waist than the group over 30 years. Those underweight preferred no pocket on the back. The intermediate-high riding level showed more fit satisfaction than those at the high level. Beginners put more importance on hip cushion, while riders over an intermediate level put more importance to sewing durability. Basic pants with beige and/or black full patch attached to the velcro hem were preferred by most riders. In conclusion, it is confirmed that design strategies in segmented riding pants market are necessary.

This study provides basic indices for the development of a pet dog's dummy. Surveys were conducted with 71 owners of small dogs weighing under 10kg as preliminary research for information on pet dogs, uses and complaints about their clothes and demographic information to investigate wearing conditions. We collected pictures of 30 products sold in 12 brands at home and abroad to analyze size, materials, and patterns and investigate the actual production conditions. The survey results on wearing conditions indicated that 'Maltese' was the breed most often raised in households. Dogs weighing 'between 3kg and 4kg' were most common. Dogs under five years of age took up 53.5%. Most of the clothes were 'S' size, followed by 'M' and 'L' Most responded, 'The overall size does not fit' as an inconvenience when worn for long. Second, most brands developed products in three sizes. The displayed details included neck and chest circumference, back length and dummy height. Cotton and artificial leather were used most often for the outer fabric, cotton for the internal filling along with wire and aluminum for some products to maintain shape and motions. Most dummies consisted of back+outer leg, belly, inner leg and sole. Sometimes, a composition line was added by the chest shape, and an incision was placed between the body and leg for breeds with thick legs. Most patterns had a composition line in the leg connected from the belly.

Live animal selection programs that favor animals with a minimum amount of carcass fat are used for improving breeding flocks of sheep. To predict carcass characteristics of live sheep using body measurements in breeding flocks, 200 male and female lambs of two fat-tailed Iranian sheep breeds (Moghani and Makui) were used. Depth of soft tissue over the 12th rib of the live animals was measured with ultrasound (ULGR) and with hypodermic needle (NGR). The height at withers (HW), body length (BL), circumference of heart girth (CH) and width of hooks (WH), were measured. All animals were slaughtered; carcasses were cut into joints and dissected. Breed had a significant effect on all of the live easurements. The Moghani breed showed a higher value for HW, CH, ULGR and NGR, compared to that of Makui. Except for soft tissue depths; ULGR, NGR and GR, the male lambs showed higher values in live and carcass measurements than females. Percentages of carcass, total fat and intermuscular fat in females were higher than that of male lambs. In spite of the higher amount of subcutaneous and intermuscular fat in female (which is usually used for their physiological need, such as pregnancy and lactation), the male lambs had a heavier fat-tail than females. There was a wide range of variation of percentage of total carcass fat and total chemical fat content of carcass in the two breeds. Eventually this wide variation could be use by animal breeders for selection of animals with a lesser amount of carcass fat. Live weight of lambs showed a relatively low correlation with percentage of carcass lean, total fat and subcutaneous and intermuscular fat. Total lean meat was predicted with relatively high coefficients of determination in the two breeds ($R^2$=0.61 and 0.89, respectively). Live weight and carcass traits were predicted using simple measurements, but with $R^2$ ranging from 0.53 to 0.93.

3D body scan data are used widely in various fields to make products and living spaces for superior human body fitness. Based on the 3D measurements of human bodies for teens in Size Korea 2013, this research provides a way of finding the representative body sizes and 3D body scan data. First, a multi-dimensional vector space consisting of many measurement items was projected onto a 2D vector space with circumference and length components via factor analysis. The representative body sizes and 3D scan data close to these values were obtained via the Mahalanobis distance in 2D space. Considering the adolescent growth pattern shown on this 2D space, males were divided into 4 age groups and females were divided into 3 age groups. Using the eigenbodies corresponding to the column vectors of the component score coefficient matrix, the representative body sizes of 13 measurement items (male) and 14 measurement items (female) for each age group were calculated. The representative body sizes and 3D scan data are very useful for modeling representative 3D human figures.

The purpose of this study is to analyze the characteristics of older women's torso shapes. The data was collected from the 7th Size Korea, which featured 453 women between the ages of 70-85. A factor analysis was performed of 31 indices, including seventeen based on height and length measurements, eight based on circumference measurements, and six based on torso flattening. The torso shape was determined from seven factors: torso flatness ratio, shape of the side upper torso, vertical size of upper torso, silhouette of the torso, silhouette of the bust and abdomen, shape of the hip, and the vertical size of the back of upper torso. The torso shapes of older women were classified into three types based on the results of the factor analysis. Type 1 is called the large rectangle type. They have the lowest degree of forward bend in the torso, the largest vertical and horizontal size, a round body shape, and the upper torso is gently curved. Type 2 is called the inverted triangle type. They also have a round body shape, but the abdominal size is relatively small compared to the size of the bust, and also have an open and drooping bust, and the biggest degree of forward bend in the torso. Type 3 is called the square type. They are characterized by drooping hips, the smallest vertical and horizontal sizes, and the gentlest curve of the torso.

Purpose: This study examines the effects of elastic band of resistance exercise for balance control of the elderly. Methods: Thirty of eighty participants in experiment subjects who demonstrated balance-impairment through the use of primary screening tests including the one leg standing test (OLST), functional reach test (FRT) and timed up and go (TUG) were selected as subjects. Fifteen subjects that underwent muscle-strengthening exercise using an elastic band were selected as the exercise group and fifteen subjects were selected as a control group. Subjects undertook a home-based exercise program three times per week for 9 weeks. Muscle strength, functional assessment and a balance test were quantitatively measured before and after the exercise regimen. Results: After muscle strengthening exercises, changes in maximal voluntary isometric contraction (MVIC) showed a significant increase in all of the lower extremity muscles of the exercise group subjects. There were statistically significant differences between the exercise and control groups for changes in the OLST, FRT and TUG, which are functional assessments of balance ability, and changes of the unit path length and circumference area, measurement items of quantitative analysis. In addition, from examining correlations between MVIC, balance ability, it was found that an increase of muscle strength in the hip joint group of muscles among the lower extremity muscles had greater improvement in correlation with balance ability in this elderly population. Conclusion: Resistance exercise using elastic bands had significant effects on muscle strengthening in elderly subjects, with a resultant increase of lower extremity muscle strength with significant improvement of balance ability.

In order to determine the mode I stress intensity factor ($K_I$) by means of the alternating current potential drop(ACPD) technique, the change in potential drop due to load for a paramagnetic material containing a two-dimensional surface crack was examined. The cause of the change in potential drop and the effects of the magnetic flux and the demagnetization on the change in potential drop were clarified by using the measuring systems with and without removing the magnetic flux from the circumference of the specimen. The change in potential drop was linearly decreased with increasing the tensile load and was caused by the change in conductivity near the crack tip. The reason of decreasing the change in potential drop with increasing the tensile load was that the increase of the conductivity near the crack tip due to the tensile load caused the decreases of the resistance and internal inductance of the specimen The relationship between the change in potential drop and the change in $K_I$ was not affected by demagnetization and was independent of the crack length.

The purpose of this study is to design an official costume of Joseon Ginyeo in the scholar’s banquet in 16th century, thereby making correct historical animation, drama costumes, and various costume contents. Every Ginyeo in and wore a long yellow coat with short front edge. 'Dan-ei', Ginyeo’s court costume, had very similar shape except color and collar, therefore the size of Dan-ei was adapted to design a yellow coat for drama actress. Ginyeo’s Jogori in these paintings was wide and long enough to cover undervelly under the edge of yellow coat, but It was designed more slim and long for better appearence and comfortable movement in my work. A skirt of Ginyeo was designed with circumference of about 360cm and length of about 105cm according as a skirt style of Joseon ladies in 16th century. Ginyeo's Jam(hairpin) was consist of a vase, a plum blossom, and a lotus pattern. And, a wide underpants with a single suspender, portable pouch, Un-hae(women’s shoes) with low heel are needed for drama actress in the role of Ginyeo. In this design, it is very important to save an estimate and time, select suitable mordern fabrics, reform discomportable points, express a charater’s role, and make a trendy appearence.

The Embedded Suction Anchor (ESA) is a type of permanent offshore foundation that is installed by a suction pile. To increase the loading capacity against pullout, three wings (vertical flanges) are attached along the circumference at 120 degrees apart. Analytical parametric study using the proposed analytical solution method has been conducted to identify the effects of several parameters that are thought to influence the behavior of ESAs. The analysis results show that the pullout capacity increases as the anchor depth and the soil strength increase, and decreases as the load inclination angle increases. The anchor having square projectional area and being pulled horizontally at the middle of its length provides the highest pullout capacity.
