This work proposes a process to derive elements of emotional materials based on trend research in the application of materials in product development. It was intended to be applied to the development of a case model, a Korean sports wheelchair, and focused on the material portion of CMF-based research. Through research methodologies such as megatrends, competitor product and part-by-part analysis, and psychological color analysis, we studied optimization, verification, and DBization of materials, and drew the final application plan through FGI verification.

The purpose of this study was to investigate the muscle activity of the lower extremity during driver swing in three-foot positions (Feet Open Stance, Feet Straight Stance, Lead Foot Open Stance). The electromyograms of gastrocnemius, tibialis anterior, and vastus lateralis during swing were measured and analyzed in three sections (take away - back swing, back swing - down swing, and down swing - follow swing). There was no significant difference in muscle activity according to foot position. Muscle activity according to phase was significantly higher in right gastrocnemius and tibialis anterior, and the left and right vastus lateralis in down swing - follow swing. In conclusion, the difference in muscle activity according to foot position is insignificant, and it is considered that the muscle activity to maintain the balance of the body increases toward the end of swing.

The purpose of this study was to investigate relations among the social support, self-esteem, and college life adjustment among college students participating in convergence leisure sports activities. Selected to attain the purpose were 300 college students that took a course on leisure sports at universities in Gyeonggi-do, Chungcheong-do, and Jeolla-do Provinces. After excluding 59 questionnaires that seemed to contain insincere answers from total 300 questionnaires, 241 were used in analysis as final valid samples. They were analyzed in frequency, reliability, and correlation analysis with the PASW Ver. 18.0 program and then confirmatory factor analysis and structural equation modeling analysis with the AMOS 18.0 program. The findings were as follows: First, support from family and support from others among the subfactors of social support had positive effects on positive ego, one of the subfactors of self-esteem, and negative ones on negative ego. Secondly, positive ego, one of the subfactors of self-esteem, turned out to have positive impacts on academic adjustment and school life adjustment, two of the subfactors of college life adjustment, whereas negative ego had negative impacts on academic adjustment and school life adjustment.

Fatty acid transporters are key mediators of skeletal muscle lipid metabolism. Several protein groups have been implicated in cellular long-chain fatty acid uptake or oxidation, including fatty acid transporter proteins (FATPs), the plasma membrane fatty acid-binding protein (FABPpm), and the fatty acid translocase (FAT/CD36). FAT/CD36 is highly expressed in skeletal muscle and known to be regulated by various factors such as exercise and hormones. Insulin-like growth factor-I (IGF-I) is a well-known regulator of skeletal muscle cells. However, it has not been studied whether there is any interaction between IGF-I and FAT/CD36 in skeletal muscle cells. In this study, the effects of IGF-I treatment on FAT/CD36 induction were examined. Differentiated C2C12 cells were treated with 20 ng/ml of IGF-I at different time points. Treatment of C2C12 cells with IGF-I resulted in increased FAT/CD36 mRNA and protein expression. After 24 and 48 hr of IGF-I treatment, FAT/CD36 mRNA increased 89% and 24% respectively. The increase of both proteins returned to the control level after 72 hr of IGF-I treatment, suggesting that the FAT/CD36 gene is regulated pretranslationally by IGF-I in skeletal muscle cells. These results suggest that IGF-I can regulate the expression of FAT/CD36 in skeletal muscle cells. In conclusion, IGF-I induces a rapid transcriptional modification of the FAT/CD36 gene in C2C12 skeletal muscle cells and has modulating effects on fatty acid uptake proteins as well as oxidative proteins.

In order to foster creative convergence talents in the era of the 4th industrial revolution, universities are changing from knowledge-oriented education to competency-oriented education, and the maker education program is attracting attention as a new educational method. Through maker program education, we tried to find out the level of convergence, creativity, caring, and communication competencies. A survey was conducted from May 2nd to May 13th, 2022 for 2nd and 3rd grade students in the Department of Radiology and Sports and Leisure who participated in the Maker Education Program at S University in Daegu City. Research results Convergence competency is 3.35 ± 0.78 points before maker program education, 4.37 ± 0.61 points after education, creative competency is 3.28 ± 0.78 points before maker program education, 4.07 ± 0.69 points after education, and caring competency is 3.71 ± 0.80 points before maker program education Points, 4.25 ± 0.64 points after training, and communication competency were 3.61 ± 0.70 points before maker program training and 4.16 ± 0.63 points after training. There was a statistically significant level difference in all four competencies compared with before training, and the level after training was improved (p<0.05). Through the operation of the maker education program, it was possible to see the effect of cultivating convergence, creativity, caring, and communication competencies. The maker education program can be seen as education for nurturing creative convergence talents in the era of the 4th industrial revolution, and I think that various maker education programs should be operated for more university students.

This study is to find out using of non-verbal communication of a golf instructor affects faith of Instructor and concentration in sports. Object of study was participants who had been taking a golf lesson and had an experience of a golf lesson at indoor and outdoor driving ranges located in Seoul and Gyeonggi Province for their own leisure sports. Among them, questionnaires from 293 persons were used for data processing and analysis of frequency, reliability test, confirmatory factor analysis and regression analysis were conducted for data processing. The conclusion from those processes are as below. First, non-verbal communication of a golf instructor has a positive effect on faith of instructor. Second, non-verbal communication of a golf instructor has a positive effect on concentration in sports. Third, faith of instructor has a positive effect on concentration in sports.

Existing sports simulators on the market focus on the motion of platform or reality expression using basic visual contents, and are limited to entertainment products. Therefore, the stimulus on 5 senses is not good enough to be applied on high virtual reality. Moreover, there are not enough professional contents to be applied to an educational sports simulator. In this paper, we developed a sport platform by separating the multi axis based common platform module and the sports application module. We designed the common platform which has 4 degrees of freedom such as surge, sway, heave and yaw motion. This platform has the purpose of stabilizing motion and minimizing interference. The changeable sport module which is attached to the common module has 2 degrees of freedom such as roll and pitch, so that it can be applied to the various fields of 2 degrees of freedom virtual reality sports such as horse riding and yacht.

This study examined the constructivist perspective and the characteristics of informal learning in relation to work place learning of sports center leaders through a theoretical approach. For this reason, informal learning has important learning meaning because sports center leaders based on informal learning enable them to develop their professionalism through workplace learning in terms of experience and practice in promoting the process of growth and learning. Can be. In addition, the leaders in the sports center coaching sites lack formal learning opportunities in workplace learning compared to office workers in general companies. Therefore, the type of informal learning and the way to improve learning should be presented. This part is considered to be an educational element as an important factor for the professionalism of sports center leaders. In addition, the establishment of a workplace learning environment in personal, environmental, institutional and organizational aspects will help sports center leaders to increase their professionalism.
