  • The smart festival costume developed in this study maximizes the design elements by attaching electronic device to clothing, and uses voice, movement, and light sensor to utilize as expression elements. In addition, as a way to maximize cultural exchanges between Korea and China, smart festival costume was developed by applying smart clothing technology to the traditional costumes of both countries. and it was exhibited for 10 days at the 'Andong International Mask Dance Festival 2018'. The smart festival costume has the effect of multiplying the dynamism and excitement of the festival by the use of colorful lighting and it has been evaluated that the experience of wearing traditional costume of both countries contributes greatly to promote international cultural exchange. However, since smart clothing is inconvenient to wear due to the use of electronic products, meticulous research for consumer safety is required for practical use. Smart devices is expected to utilize for the development of traditional culture resources and the fashion industry in the future.

  • The demand for truck bus radial (TBR) tires with enhanced fuel efficiency and wear resistance have grown in recent years. In addition, as the issue of particulate matter and air pollution increases, efforts are being made to reduce the generation of particulate matter. In this study, we investigated the effect of varying the content of butadiene rubber (BR) on the properties of the rubber compounds and the amount of particulate matter in the TBR tire tread compound. Furthermore, we utilized carbon black in the NR/BR blend compounds owing to its excellent compatibility, and we used silica in the ENR-25/BR blend compounds because it can interact chemically with epoxide groups. The NR/BR blend compounds and the ENR-25/BR blend compounds were evaluated by varying their BR content between 20 phr and 30 phr. The results showed that the ENR-25/BR blend compounds had superior wear resistance than the NR/BR blend compounds. This was caused by the interaction between silica and ENR. In addition, it was confirmed that the increased wear resistance as the BR content increased. Furthermore, compared to the NR/BR blend compounds, ENR-25/BR blend compounds exhibited a lower tan 𝛿 value at 60℃ because silica was used as filler. This indicates a higher fuel efficiency. The measurement results for wear particulate matter showed that as increasing the BR content resulted in generation of less wear particulate matter. This was caused by the increased wear resistance. Moreover, the ENR-25/BR blend compounds with excellent filler-rubber interaction exhibited lower quantities of generated wear particulate matters as compared to the NR/BR blend compounds.

  • Magnetorheological elastomers (MREs) are a type of “smart” material, and their properties can be controlled rapidly and reversibly under the influence of an external stimulus. The application of an external magnetic field can change the shear modulus, hardness, and friction coefficient of MREs. The friction can cause vibration; moreover, the vibration can affect friction. The change of friction depends on the relative motion, normal force, roughness of the rubbing surfaces, material type, temperature, lubrication, relative humidity, and vibration condition. As MREs are a type of “smart material,” their friction coefficient can be reduced by applying an external magnetic field—the applications of this feature in engineering have been widely studied. However, the friction properties of MREs under vibration have not been tested to date. In this study, MRE samples and a reciprocating friction tester were fabricated. The friction coefficient was measured to evaluate the friction properties under various vibration conditions; subsequently, the wear depth and wear surface profile of the MRE were observed in order to evaluate the wear properties. The results show that the friction coefficient of the MREs decreased when a magnetic field was applied. Moreover, the friction coefficient decreased when the vibrational amplitudes increased. The wear depth of the MRE also decreased as the vibrational amplitudes increased.

  • With the spread of smart manufacturing, one of the key topics of the 4th industrial revolution, manufacturing systems are moving beyond automation to smartization using artificial intelligence. In particular, in the existing automatic machining, a number of machining defects and non-processing occur due to tool damage or severe wear, resulting in a decrease in productivity and an increase in quality defect rates. Therefore, it is important to measure and predict tool life. In this paper, ν-ASVR (ν-Asymmetric Support Vector Regression), which considers the asymmetry of ⲉ-tube and the asymmetry of penalties for data out of ⲉ-tube, was proposed and applied to the tool wear prediction problem. In the case of tool wear, if the predicted value of the tool wear amount is smaller than the actual value (under-estimation), product failure may occur due to tool damage or wear. Therefore, it can be said that ν-ASVR is suitable because it is necessary to overestimate. It is shown that even when adjusting the asymmetry of ⲉ-tube and the asymmetry of penalties for data out of ⲉ-tube, the ratio of the number of data belonging to ⲉ-tube can be adjusted with ν. Experiments are performed to compare the accuracy of various kernel functions such as linear, polynomial. RBF (radialbasis function), sigmoid, The best result isthe use of the RBF kernel in all cases

  • This study aimed to analyze consumers' acceptance of sports applications and smart sportswear to better design technology-enhanced walking exercise wear for the Baby Boomer generation based on their cohort characteristics. A questionnaire with items related to acceptance of existing smart sportswear design, functionality, and usability as well as existing sports application design, functionality, and usability was sent to consumers aged 50-65. Of 163 questionnaires distributed, 150 were used for analysis. The results showed that middle-aged consumers were aware of smart sportswear's functional stability, but were concerned about care, durability, and convenience. Middle-aged consumers were also aware of sports applications as educational functions for obtaining new information. Additionally, they found sports applications to have lower perceived convenience and accessibility relative to the young generation, highlighting the need for simple instructions and explanations for sports application planning. Based on these results, we propose "Everyday design for general sportswear," "Functions based on consumer's preference," "Enhanced design for durability and management convenience" for designing and planning walking exercise wear for middle-aged consumers, and "Convenient application organization" and "Educational exercise contents" for application planning for walking exercises.
