The purpose of this study is to investigate the effect of wearing sweat suit on sweating rate during jogging. 4 healthy female students served as subjects in the experimental chamber which was controlled 22$\pm$1$^{\circ}C$, 60$\pm$10%RH and no wind. The experimental clothes were Sweat Suit (SS) and General Suit (GE), SS was the product of R sports wear company which was consisted of long-sleeved jumper (100% polyester) and full length trousers (100% polyester) and GE were consisted of long sleeved shirt (100% cotton) and full length trousers (100% cotton). The subject wore same socks and shoes in both experimental clothes SS and GE. The subject reported at the experimental chamber at the same time on each experimental day. exchanged their clothes to the experimental clothes SS or GE, wore all sensors for the physiological measurements and had a rest in a sitting posture about 40 minutes. After rest, the subject carried out 30 min jogging on the tread mill with the speed 3.6miles/hour and during the jogging rectal temperature, skin temperatures (7 sites of the skin surface), heart rate, VO2, and evaporative weight loss were measured continuously and compared between two experimental clothes SS and GE. The major findings were as follows : The increase in rectal temperature during 30 min jogging was higher in experimental clothes SS than in GE and mean slim temperature kept higher in SS than in GE. VO2 and heart rate were a little bit higher in the later period of jogging in SS than in GE. The evaporative weight loss was greater in SS than in GE. These results indicate that the thermophysiological responses and sweating rate differs according to the wearing suit even though the subject performed same exercise.

The appearances and geometry structures of knitted fabrics have important effects on their functions as textile fabrics. Structural design of the woven fabric, prior to the manufacturing processes in the weaving mill, often leads to a similar predictable appearance in the final outcome with the corresponding weave design. The increase of the employment of elastic textile yarns in knitting fabrics for comfort stretch or outdoor sports wear knit products has, however, resulted in difficulties in predicting the final appearance of the knit structure design. Due to the stretchability and exceptional recovery behavior of the elastic yarns such as polyurethane elastomeric yarns, the appearance of the final product often differs from the initial knit design. At textile CAD program for preparing tricot knit designs has been employed in this study to predict the two dimensional appearance of the design. The similarities between the designs and corresponding knit products seem to be acceptable for the two-dimensional textile CAD program in this study. However, when elastomeric yarns are partially employed in the polyester filament tricot product, a considerable amount of departure from the design is apparent due to the constriction and/or deformation of property differences in the elastomeric yarns and polyester filament yarns. Therefore, another purpose of this study is to measure the departure of the final tricot product from the initial tricot design, especially in the case employing elastomeric yarns in the knit structure together with regular polyester filament yarns. For measuring the three-dimensional departure, a 3D scanning system has been used for the mesh reconstruction of the fabric specimen. Hopefully, the result from this study will be used as a guide to modify and improve the current textile CAD program proposed for the two-dimensional simulation of the tricot.

Focusing on costume research to set image of Korean wrestling that has potential power as a traditional and cultural item, the purpose of this research is to systemize Korean wrestling uniform and offer suggestions regarding visualization, and to carry out basic ground research to develop Korean wrestling uniform design. For the basic part, I compared world wrestling and Korean wrestling in an effort to learn more about the history of wrestling uniform along with its transitional changes. And for the practical part, I studied the criterion of the current wresting and its uniform, and classified the aesthetic points of Korean wresting uniform into four categories in the view point of design ground research: tradition and uniqueness, usability and compatibility, symbolism and ornamentation, variety and unification. It is concluded that the most important part in designing Korean wrestling uniform lie in how to consistently visualize it based on the above mentioned aesthetic points. As the theoretical research on aesthetic parts of Korean wrestling uniform, this research finds its meaning in suggesting guideline for design concept and development while planning traditional and cultural costume design which will be materialized in the follow-up research.

The purpose of this study was to develop an e-textile using LEDs that can enhance visual and functional effects, and to identify their applicability to sportswear. By applying the design elements of fashion design concretely with LEDs, an e-textile design module is developed and that module is applied to the product, so LED application design can be proposed for use in a practical product. E-textiles have been divided into five categories, and their usefulness were verified by applying e-textiles to men's and women's sportswear. The product beign considered has a built-in tilt sensor, which illuminates the LEDs according to the user's movements, and allows the LEDs to be turned on or off in accordance to the user's preference. E-tatoo is a type of LED application that enhances the appearance by placing LEDs on a small area, emphasizing origin points, just like an actual tattoo. Designed with LEDs arranged in a straight line and various curved forms, e-strips can provide a function that matches the characteristics of each section of clothing or fashion item. E-wappen uses about 7-10 LEDs to give motifs a strong sense of visibility, thus adding to their vibrancy. E-panels and e-clothes were able to produce creative and high-value textures. It is also expected to be used for special purposes or bags as it is possible to produce high value-added textures that are creative and aesthetically beautiful. For instance, a progressive LED string on the straight line of female leggings can further emphasize rhythmic movements during exercise, and e-wappen also serves the purpose of nighttime protection. It is also believed that the application of dance or dance-related sportswear will make the movement of the performance more intense and lively.

The objective of this study was to develop lightweight, stretchable, tight-fit smart sportswear using the conductive yarns into the garment and demonstrating its usefulness. Sportswears with the ability to control LEDs with respect to lighting of the surrounding were developed by applying embroidery with conductive yarns to 2 types of men's T-shirts and 2 types of women's leggings pants for outdoor activities and exercise purposes. LEDs were applied to the front and back of men's T-shirts and to the rear of the waist of women's leggings. Men's T-shirts were printed where the LEDs were to be applied, and inside, they were embroidered with conductive threads on the hot-melt fabric to be attached, and then connected with LED. Women's pants were embroidered on the elastic band, in the form of a sine wave that gives it ability to stretch, and finally the elastic band was hidden inside the waistband. The operation of the light sensor in the dark provided the ability to protect joggers from night drivers or cyclists. LEDs were activated when the wearer turns on the fashionable device on his/her shoulder by pressing it. It was able to reduce the risk of accidents by giving recognizability to vehicles, bicycles, and athletes approaching or passing by at night, and securing safe distance from vehicles, etc. Internal embroidery technology had the same flexible and lightweight functions as ordinary clothing products, making it possible to apply to tight-fit smart T-shirts or leggings pants designs.

The purpose of this study was to investigate the effects of 12 weeks of abdominal breathing exercises, through AB spur, on weight and BMI, % body fat, and waist-hip ratio in healthy college students. The subjects consisted of 20 obese young college students, and all of whom had no other health complications. The subjects were shown in detail the proper way to utilize the equipment and practice abdominal breathing in a laboratory setting. They were told to wear the AB spur for at least six hours a day in order to induce abdominal breathing exercise. Because the subjects were students, most of the abdominal breathing exercises took place while they were sitting in lectures at school, and they wore the equipment for 12 weeks. At 4, 8, and 12 weeks after the subjects started using the AB spur, there were significant decreases in weight, % body fat, BMI, and waist-hip ratio (p<0.05). In conclusion, the results of the stud suggest that abdominal breathing exercise may be a good weight loss method, as well as a beneficial way to decrease obesity factors, in obese college students.

The purposes of this study were to a analysis of friction relation between tennis outsole and tennis playing surfaces. Tennis footwear is an important component of tennis game equipment. It can support or damage players performance and comfort. Most importantly athletic shoes protect the foot preventing abrasions and injuries. Footwear stability in court sports like tennis is incredibly important since it is estimated that as many as 45% of all lower extremity injuries occur in the foot and ankle. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. The friction force opposes the motion of the object. Friction results when two surfaces are pressed together closely, causing attractive intermolecular forces between the molecules of the two different surfaces. The outsole provides traction and reduces wear on the midsole. Today's outsoles address sport specific movements (running versus pivoting) and playing surface types. Different areas of the outsole are designed for the distinct frictional needs of specific movements. Traction created by the friction between the outsole and the surface allows the shoe to grip the surface. As surfaces, conditions and player motion change, traction may need to vary. An athletic shoe needs to grip well when running but not when pivoting. Laboratory tests have demonstrated force reductions compared to impact on concrete. There is a correlation between pain, injury and surface hardness. These are a variety of traction patterns on the soles of athletic shoes. Traction like any other shoe characteristic must be commensurate and balanced with the sport. The equal and opposite force does not necessarily travel back up your leg. The surface itself absorbs a portion of the force converting it to other forms of energy. Subsequently, tennis court surfaces are rated not only for pace but also for the percentage of force reduction.

This study was undertaken among students majoring in Emergency Medical Technology, to comprehend the knowledge, attitudes and preventive behaviors associated with MERS. This study further provides basic data for education related to MERS prevention. A total of 167 students were enrolled in the study. Evaluation of MERS education revealed a higher number of inexperienced subjects: 74 experienced(44.3%) vs. 93 inexperienced(55.7%). Assessing the attitude items for MERS revealed that "have to wear personal protective equipment when dealing with MERS patients" ranked highest (average, 4.54 ± 0.87), whereas "washed my hands more often than usual" ranked highest (average, 3.82 ± 1.06) in the prevention items for MERS. Analyzing the correlation between attitude towards MERS and preventive behavior revealed that "canceled or delayed meeting with friends, eating out, watching sports, shopping, etc." showed that, although negatively correlated, a greater attitude showed a higher level of prevention (r=-0.63, p<0.004). Taken together, results of this study indicate the necessity to develop an education program that improves the level of education and knowledge about MERS, and to impart this education systematically and repeatedly.
