The purpose of this study is to seek the change of body surface according to cycling motions and to give suggestions to the pattern and spare space between body and wear in each bodily parts to be heavily considered for making the bicycle wear. The cycling motions were analyzed by taking the sequential pictures of cycling covering motion by a digital camera. The experiments with gypsum were toward a woman in her twenties. We draw the line standard of the body's surface, separated their gypsum-replicated fragments of body's surface following the analyses of the change in their lengths. As the motions were made, we decided the degree of the changed length as spare space when compared the erected posture with the cycling posture, presenting the pattern of the cycling wear with the preparation of wears for testing. After that, the essential experiments were conducted toward three cycle players wore our experimental wears. Regards their evaluated appearance, evaluations over three points were obtained from all parameters except the width of front armhole. Accordingly, our experimental wears were remarkably understood as a relatively proper wear as bicycle wear.

This study provided basic data to develop functional and fitness cycling wear for cyclists. We analyzed the domestic and overseas cycling wear brand patterns for tops and tights as well as compared pads attached to tights. The results were as follows. The tops of the cycling wear were designed with cutting lines in the lateral or yoke in the back to reflect cycling posture. It is necessary to study if there is a difference in the air resistance or fitness of the athlete. The sleeve hem band affected by arm movement during cycling, proper sewing and band pressure are also important. The tights have a brand that does not insert a band in front of the waist in consideration of the cyclist's breathing. It should take into account methods of constructing a proper garment pressure that does not interfere with cycling. Analyzing the cycling pad indicated that the three-dimensional shape and size of the pad show many differences for each brand, indicating a difference in cycling movement suitability. In addition, many of the cutting lines should account for the productive aspects because of the high consumption of the fabric in order to design a pattern considering the cycling posture.

In this study, a cycling smart wear for measuring cycling posture and motion was developed using a three-dimensional motion analysis camera and an IMU inertial sensor. Results were compared according to parts to derive the optimal smart device attachment location, enabling correct posture measurement and cycle motion analysis to design a pattern. Conclusions were as follows: 1) 'S-T8' > 'S-T10' > 'S-L4' was the most significant area for each lumbar spine using a 3D motion analysis system with representative posture change (90°, 60°, 30°) to derive incisions and size specifications; 2) the part with the smallest relative angle change among significant section reference points during pattern design was applied as a reference point for attaching a cycling smart device to secure detachable safety of the device. Optimal locations for attaching the cycling device were the "S-L4" hip bone (Sacrum) and lumbar spine No. 4 (Lumbar 4^th); 3) the most suitable sensor attachment location for monitoring knee induction-abduction was the anatomical location of the rectus femoris; 4) a cycling smart wear pattern was developed without incision in the part where the sensor and electrode passed. The wearing was confirmed with 3D CLO. This study aims to provide basic research on exercise analysis smart wear, to expand the smart cycling area that could only be realized with smart devices and smart watches attached to current cycles, and to provide an opportunity to commercialize it as cycling smart wear.

This study analyzed the consumer awareness of cycling wear using web mining, one of the big data analysis methods. For this, the texts of postings and comments related to cycling wear from 2006 to 2017 at Naver cafe, 'people who commute by bicycle' were collected and analyzed using R packages. A total of 15,321 documents were used for data analysis. The keywords of cycling wear were extracted using a Korean morphological analyzer (KoNLP) and converted to TDM (Term Document Matrix) and co-occurrence matrix to calculate the frequency of the keywords. The most frequent keyword in cycling wear was 'tights', including the opinion that they feel embarrassed because they are too tight. When they purchase cycling wear, they appeared to consider 'price', 'size', and 'brand'. Recently 'low price' and 'cost effectiveness' have become more frequent since 2016 than before, which indicates that consumers tend to prefer practical products. Moreover, the findings showed that it is necessary to improve not only the design and wearability, but also the material functionality, such as sweat-absorbance and quick drying, and the function of pad. These showed similar results to previous studies using a questionnaire. Therefore, it is expected to be used as an objective indicator that can be reflected in product development by real-time analysis of the opinions and requirements of consumers using web mining.

This study intends to analyze the up-cycling trend that is attracting great attention these days and its internal meaning in the context of fashion art. And, based on this, to provide enhanced value and creativity in the future fashion artwork and design businesses, keeping abreast of further fashion art developments. As part of the study methodology, both a literature review and a case study were carried out, along with an examination of up-cycling and research into related pictures and content. The materials covered in this work include design and fashion related books and domestic and foreign magazines from 2000 to 2011, when the up-cycling movement was initiated as a form of eco-friendly design. For the analysis of fashion art pieces, generic terms included art wear, wearable art wear, and unwearable art. Case review was followed by the works of artists shaping their fashion concept and meaning entirely from abandoned clothes and fabrics, waste materials, and their art collection. Consequently, key elements of the value of up-cycling fashion art are that it is eco-friendly, has a unique identity, and reflects multi-dimensionalism. This research saw the integration of fashion with other variables, artistic attributes, and reuse of resources. This could lead to a new realm where value-addition is formed and extended, thus providing another chance for the fashion industry.

The purpose of this study is to grasp the actual wearing conditions, inconvenience and problems with cycle wear. To attain this purpose, a questionnaire was completed by direct observation and by interviewing bicyclists. The questionnaire was given to 273 bicyclists. The questionnaire consisted of items that are related to concerns with dressing appropriately and enhancement of physical performance through dress. Following are the results of this study. According to the survey, many of them purchased imported cycle wear rather than national cycle wear, and the satisfaction according with purchase rate was low. Bicyclists were uneasy with finding right size cycle wear especially for women. It turned out that the area of the knee and elbow are mostly the areas that they get hurt while riding. Even though the knee and elbow are the mostly hurt area, bicyclists do not prefer to wear appropriate protector for the knee and elbow to excel in their performance in cycling. In material related questions, lower dissatisfaction was indicated for the lints caused by fraction. Average satisfaction was indicated for the distortion after washing, changes in color, touch of the fabric, matters with static and sweat. With regard to the areas where the bicyclists felt discomfort was highly indicated with lower-body clothing. Discomfort was highly indicated with crotch area when riding long period of time. Also when riding a cycle, discomfort was indicated with the leggings cuffs when it comes upward with riding motion. Most of the bicyclists felt the tight fitting leggings were embarrassing.

This study investigates changes in the mechanical behavior, such as changes in indentation load-displacement curve, wear resistance and contact fatigue resistance of thermal barrier coatings (TBCs) by thermal cycling test and thermal shock test. Relatively dense and porous TBCs on nickel-based bondcoat/superalloy are prepared; the highest temperature applied during thermal durability test is $1350^{\circ}C$. The results indicate that the porous TBCs have relatively longer lifetime during thermal cycling and thermal shock tests, while denser TBCs have relatively higher wear and contact fatigue resistance. The mechanical behavior is influenced by sintering of the TBCs by exposure to high temperature during tests.

Upper body types were classified to develop the sizing system of the cycling wear top for the high school male cyclist. The research methods were performed using the anthropometric measurements of 111 high school male cyclists that included cluster analysis was performed. The research results are as follows. Type 1 (23.4%) has the longest biocromion length, is the tallest of the three types and a proper body type. Type 2 (25.2%) has the largest weight and developed muscles in the chest parts. Type 3 (51.4%) is the shortest of the three types and is a skinny body with a bending back. In order to develop a sizing system, the 12 anthropometric measurements were selected for correlation analysis. The bust circumference and stature were presented as the control dimensions of sizing system. The waist front, waist back length and biacromion length were less correlated with other items; consequently, they were independent items and were set as referable dimensions. Therefore, it was proposed as a sizing system because the 5 cm of bust and 5 cm of stature have a high coverage by body type. The total coverage rate was 81.9%.

This study aims to analyze short sleeve cycling tops from three brands for a change in garment fit and pressure depending on the static and cycling postures. To this end, it used a 3D virtual garment system to virtualize the garments. Further, a cross-section of the 3D virtual garment data was obtained, and the space length was measured in the design-X program to prove the objectivity of the 3D virtual garment. The results indicated that three brands had a large space length at the front than the back because of the bent posture in cycling. Therefore, appropriate ease was required for the waist and abdomen. Although there were various cutting lines of the bodice panel by brand, the design of the cutting lines should consider the changes in the surface to reflect the bent posture in cycling. The results of this experiment confirmed that the wrinkles present in the 3D virtual garment were reflected in the cross-section and that the space length was small in the high-stress area, as shown in red. Therefore, it was proven the stress of the 3D virtual garment could be used for 3D virtual garment evaluation.
