This study investigated the wearing status and design preferences regarding athleisure wear, focusing on young women in their 20s and 30s and middle-aged women in their 40s and 50s participating in yoga and fitness activities. A total of 332 valid samples were used for the survey by setting the same number of samples for each age group. The results showed that young women in their 20s and 30s exhibited weight control, and middle-aged women in their 40s and 50s maintained their health in relation to exercise. Athleisure wear brands were found to prefer foreign brands over domestic brands. When purchasing athleisure wear, the foremost considerations were material functionality, fit according to body shape, and reasonable prices. The preferred athleisure wear leggings design showed that both middle-aged women and young women preferred nine-piece leggings. Women in their 20s to 50s were found to purchase and acquire information on athleisure wear online. Hence, the pattern of life is rapidly transitioning from offline to online, and the market structure of athleisure wear is gradually transitioning toward an omni-channel society with a distribution market structure that combines information technology(IT) and mobile technologies. Therefore, It is required to develop athleisure wear of various functional products that meet the trends according to the global market environment and consumer class.

Technology status was investigated by analyzing patents and development cases of wearable robots. Development direction of wearable robot for wearability was also suggested by understanding the problems of wearability from development cases through the FGI technique. The number of patents per technical field was the most in the field of strength support, but AI in the technology field was different in each country; Korea was found to be poor in the category of daily living assistance. The number of patents by technology category was the most in the category of muscular strength assistance. However, the values of AI in the technology category were different in each country; Korea was found to be poor in the category of daily living assistance. Development cases were focused on rehabilitation, so development is not fulfilled uniformly by use purpose. By wearing body parts, robots with single function type were mainly developed. Rigid material robots were mainly developed. It was confirmed that wearable robot technology is not developed evenly in the category of application because it is in the early stage of the technical proposal and centered on main performance improvement. We derived twelve wearable conditions for wearable robots: Shape and Size Appropriateness, Movement Appropriateness, Composition Appropriateness, Physiological Appropriateness, Performance Satisfaction, Ease of Operation, Safety, Durability, Ease of Dressing, Ease of Cleaning, Portability and Ease of Storage and Appearance Satisfaction. Finally, the development direction of a wearable robot for each wearable condition was suggested.

실용성은 우수하나 위생성과 고급성이 매우 떨어지는 PET직물을 세리신을 이용하여 표면 개질함으로서 새로운 기능성을 부여하고자 하였다. Glutaraldehyde를 사용하여 세리신을 PET 직물에 가교시킬 경우 약 0.22%의 부착율을 보였으며, GA 수용액의 pH는 산으로 갈수록 좋고 세리신 수용액의 pH는 등전점에서 멀어질수록 반응이 쉽고 균일하게 일어났다. PDC 방법으로 세리신을 PET 직물의 부착시킬 경우 0.6%의 부착율을 보였는데 이는 가교제에 의한 경우보다 많이 부착이 되지만 직물에 균일하게 부착되지 않았다. 가교제 또는 PDC 방법을 통하여 PET 직물의 표면을 세리신으로 처리해도 수분율에 큰 영향을 주지 않았다. 즉 감량가공처리만으로도 흡수율이 크게 증가하였으며 이후 세리신을 처리하더라도 흡수율은 향상되지 않았으나 마찰대전성은 크게 향상되었다.

The purpose of this study was to investigate the dyeability of silk fabrics with sweet potato stem leaf extract. To obtain the optimal dyeing conditions it was examined at various dyeing conditions(temperature, pH, time and bath ratio). The dyeability and the depths of shade which were evaluated in terms of K/S and CIELAB color difference values of the dyed and mordanted fabrics were also investigated. After dyeing, various color fastness(wash fastness, dry cleaning fastness, light fastness, rub fastness, and perspiration fastness) was measured and reviewed for UV protective, deodorant and antimicrobial functionality. The optimun output, as a result, was shown at 100% of dye concentration, $90^{\circ}C$ of dyeing temperature and 80 minutes of dyeing time while in terms of dye uptake depending on the kind of mordants and mordanting, it was found that among four mordants of $Alk(SO_4)_2$, $CuSO_4$, $SnCl_2$, and $FeSO_4$, post-mordanting with $SnCl_2$ showed the best results. Color fastness to dry cleaning, washing and rubbing was found strong at grade 4-5 and the grade to perspiration was as good as 3 while to light fastness was good at 4 as well. In aspects of functional properties, it showed excellent results of 98.3% UV protection rate and 88% deodorization rate. Antibacterial activity was 99.9% against staphylococcus aureus and 73.3% against klebisella pneumoniae. In conclusion, we validated that the dyestuffs from the disused sweet potato stem leaf extract would be useful as a natural dye material using the optimized conditions and dyeability for silk dyeing.

Investigation for industrial revolution has been recognized as an important issue of historical science, since industrial revolution itself was a historical moment in modern economic society and in the forming of modern capitalistic culture. If clothing culture had been developed in close relation to social culture. industrial revolution which gave a base for modern capitalistic culture, would be a birth of modern clothing as well as a moment for modernization of western clothing. As it takes for granted that industrial revolution, historical phenomenon is a developmental base of modern clothing culture. This study tried to enlighten the origin of modern clothing culture phenomenon with investigation of industrial revolution as a historical moment in modern clothing culture through documental study. Historian's point of view and method of studying are important when we investigate the clothing phenomenon. Although culture phenomenon of industrial revolution has been evaluated usually through socialogical aspect, studying for clothing culture phenomenon must be carried out on aethetical as well as well as sociological aspect, on account of dualism of clothing, as it is social and artistic nature. In 19th century, there were technical improvement, changing patterns of production, changing social relation and beginning of mass culture. At the same time clothing culture phenomenon was changed in relation to modern capitalistic society. The findings of the study could be summarized as follows. 1. Technical improvement in textile industry and fitting process brought about mechanization of clothing industry. 2. Appearance of popular clothing culture made it easy to spread to various classes of society. 3. Development of transportation system and communication channel made it internationalization of western clothing. 4. Recognition of importance in functional style of clothing. 5. The pursuit of modern aesthetics made rapid changing mode of clothing. Above distinctive features of modern clothing culture were derived from by-product of machinary culture, mass culture, internationalism, rapidly changing mode of various culture during industrial revolution. Industrial revolution was a change of the material world as well as in industry owing to machine advent, then the culture part that displayed directly these changes was the plastic arts of living that mould the material. The problem of clothing construction caused by industrial revolution was solved by pursuing the functional aesthetics. Clothing phenomenon as a process of value transfer participates mass culture in closs relation to general change of various culture caused by industrial revolution. Therefore western clothing gained the qualities of modern culture, condensed as function, and popularity in the process of modernization.

This study aims to develop protective pants to relieve impact from falls and to present basic data for the development. The survey results are as follows; First, 45% of the respondents were in their 60s and 55% of them were in their over 70s and older. Also, 64% of them have fallen once for the past year and 36% of them have fallen twice or more. The older they were, the more there were those who have fallen twice or more. This indicated the older people has experienced more fall accidents again after a initial fall accident. Second, as per accident situations, the survey showed that fall accidents happened the most in the winter and in the afternoon (12-18 pm). Also, it happened on a street mostly and they were wearing sneakers or hiking boots when they got a hurt slipped in a front or side by missing their step in a walk. The injury areas are mostly knee and ankle. They had the bruises or a sprain in their knee and ankle mostly. The rate of bone fracture was 19.5%. Therefore, the protection area to falls in lower body is the knee. But hip and hip joint should be protected with knee as well because those are usually be broken when it is damaged. Third, approximately 80% of those who were hospitalized for treatment had surgery. Patients who had surgery were rather in their over 70s than in their 60s. The older they were, the more serious their fracture was. The period of hospital or outpatient treatment is more than three weeks in many cases. They responded their health got worse after falls. Aftereffects of accidents were physical discomfort, anxiety and medical costs. Falls to the old makes physical damage, psychological damage, which cause reduced physical activity and the increased cost of health care with economic losses. So it results on a negative impact on the life of the old. Fourth, elderly females were rarely aware of impact protective clothing and they have never purchased such clothing. For impact protective pants, the major consideration was suitable design for their body types. They liked casual style with front or side pockets and simple designs without any patterns or decorations. As per pants materials, they responded that they need functionality, activity and elasticity. Among the functional points, insulation of cloths are considered importantly, so the heat reservance of material in the impact protective pants should be considered carefully.

The purpose of this study was to develop a caregiver's uniform that is appropriate for nursing and to improve movement adaptability as well as having a pleasing appearance. Based on the results of preliminary study, I investigated the inconvenience and problems with the existing uniforms and made a sample uniform taking into consideration the design, the material, and the pattern. We carried out a sensory assessment and quantitative assessment in order to compare the sample uniform with existing uniforms. Following are the results of this research. The top is a short-sleeved blouse with a round neckline having no collar and with armpit gussets. The armpit gussets are semicircles and the inverted pleats in the back are an improvement designed for activity. The pants are long reaching to the ankles with elastic in the waist so that the waist measurement may be adjusted. The length of the pants can be adjusted with strings and the pants have a funnel-shaped pocket for adjustment of length. We used a mix of polyurethane and polyester for the outer cloth of the uniform in order to improve activity function and used $Coolever^{TM}$, the sanitary textile that absorbs moisture well and dries in a short time, for gussets in the armpits, which is the heavy sweat area. The appearance assessment and movement adaptability assessment were performed with 5 subjects and 9 experts. For the results of the assessment, the sample uniform was appraised to be better than the existing uniforms in every item of an appearance comparison assessment except for the neckline assessment by the experts. As for the assessment of movement appropriateness and wearing assessment, the same subjects were used for analysis. As the results of the assessment, the sample uniform was rated higher than the existing uniforms in movement adaptability and pleasing appearance.
