The distinction between high culture and popular culture is gradually weakening. Taste is becoming a new standard to distinguish culture. This research analyze sports film by taste cultural perspective. In perspective of Universality, and is Both emphasized the individual attitude of sincere effort. This can be interpreted as a capitalist ideology. Analyzing the two films as a global and local tastes culture, shows a new world that follows the birth of a star player and deifies the football beyond borders and races. shows the distrust of the system through the K-League Citizens' Club and the trust in individual who does their best in the meantime.

In this paper, the signals of the sensor for extracting characteristic parameters of the rotor are collected and the performance of the extraction technique is analyzed. To this end, a vibration test league was developed for conducting model tests to analyze the signal characteristics under normal operation. As a result, it is judged that no change in the measured the raw data amplitude will occur in the acceleration sensor with the unbalanced mass measured from the acceleration sensor. Performing FFT showed a significant increase in amplitude of the rotational frequency of 20 Hz as the unbalanced mass increased. The analysis results according to the change in the unequal mass of the speed sensor also showed a significant increase in the 1X Harmonics component, such as the acceleration sensor. There was no change in the amplitude of the acceleration sensor data when the misalignment occurred, and for the Envelope data, the amplitude of 2X (40 Hz) was increased depending on the degree of misalignment. The velocity sensor at change of misalignment also showed similar results to the acceleration sensor, and the peak was reduced at 600 Hz as the load increased in the frequency spectrum.

This study aimed to identify the influence of soccer star's human brand on attitude and attachment to the club, providing the importance and implications of brand management of star players in the club. Therefore, a non-face-to-face mobile survey was conducted from January 14 to March 5, 2021, and a total of 348 copies of data were used for the final analysis. Data processing used the SPSS (ver.21.0) program to conduct frequency analysis, internal consistency and exploratory factor analysis, correlation analysis, and multiple regression analysis. The main results of this study are as follows. First, the human brand of a soccer star has been shown to influence the attitude of the club in the order of ethicality, attractiveness, and differentiation. Second, the human brand of a soccer star has been shown to influence the attachment of the club in the order of ethicality, attractiveness, and differentiation.

With the development in the IT industry and the growth in the game industry, user's game data is recorded in seconds according to various plays and options, and a vast amount of game data can be analyzed based on Bigdata. Combined with business, Bigdata is used to discover new values for profit creation in various fields, but it is utilized in the game industry in insufficient ways. In this study, considering the characteristics of the subdivided lines, we constructed a win-loss prediction model for each line using the game data of League of Legends, and derived the importance of variables. This study can contribute to planning of strategies for general game users to get information about team members in advance and increase the win rate by using the record search sites.

This study was conducted to investigate the relationship between performance level and ego orientation and task orientation, which are sub-factors of achievement goal orientation, targeting the Korean youth badminton national team. Accordingly, two null hypotheses were established and tried to verify that there would be no difference in ego orientation and task orientation according to the performance level of the badminton youth representative players. A total of 92 middle and high school students were divided into upper and lower performance groups, and the differences between ego orientation and task orientation were investigated, respectively. For the measurement, We used sports achievement goal orientation (task and ego orientation in a sports questionnaire, TEOSQ). Data were analyzed by performing frequency analysis, reliability analysis, and independent t-test. As a result, there was no statistically significant difference in both the ego orientation and task orientation between the upper and lower groups of performance. We discussed based on the research results.

Recently in the gaming market, immoral game behaviors such as flaming, trolling, and illegal program use have drawn attention as serious problems. With 209 gamers of , this study analyzed the effects of perception toward in-game rules, social identity, moral identity, and moral positioning with control of gender and gaming time. Results showed that moral identity and formal moral perception toward in-game rules had positive effects while moral positioning and social identity had negative effects on immoral behavior. Notably, moral identity had interaction effect with moral positioning.

In this study, the correlation between sports records and weather data was analyzed using the big data analysis method. To this end, data was collected by API and crawling, data was processed, statistics were performed, and data visualization was performed. The subject of this study was a player who entered the regular at-bat among outfielders in the 2019 KBO League. In addition, meteorological data were analyzed by using the unpleasant index and above 70 and below 70. As a result of the study, in the various hitting indicators, which are the records that pitchers intervene, the higher the unpleasant index, the better the outfielder's record, but pitchers, walks, pitches, pitching success rates, pitches per turn, pitches per game From the records of the back, it was found that the outfielder made the pitcher difficult. It is expected that this study will help the development of the sports data industry and the performance of baseball players, baseball teams, and coaching staff.

An experimental study was conducted to observe the spray characteristics for different flow rates and rotating speeds of a rotating fuel nozzle of a slinger combustor. The water spray ejected from the nozzle orifice was visualized using a high-speed camera and a light source. It was confirmed that the atomization was improved, as the flow rate decreased and rotating speed increased. The characteristic maps for the spray characteristics and performance parameters showed that the aerodynamic Weber number and the liquid-air momentum flux ratio were associated with the liquid primary breakup, and the liquid-air momentum flux ratio and Rossby number were closely correlated with the liquid ejection mode.

Organic residues are substances derived from diverse natural sources. Recent scientific analysis of organic residues has yielded important information in restoring the lifestyles of ancient peoples. In this study, the organic material contained within the celadon oil bottle of the Goryeo dynasty, excavated from the Soejoul site in Geumneung-dong, Chungju, was analyzed using Fourier-transform infrared spectroscopy (FT-IR) and gas chromatograph-mass spectrometer (GC-MS). The results showed that the organic materials in the bottle were plant-derived oils. In particular, polyunsaturated fatty acids and phytosterols were detected using GC-MS analysis. Sesamin components were also identified. Sesamin, which is a characteristic component of sesame seeds, is a lignan and an antioxidant. As the organic residues in the oil bottle were derived from sesame seeds, it is presumed that sesame oil was stored in the bottle.
