After several significant nuclear accidents, public attitudes toward nuclear energy technologies and facilities are considered to be one of the essential factors in the national energy and electricity policy-making process of several nations that employ nuclear energy as their key energy resource. However, it is difficult to explore and capture such an attitude, because the majority of prior studies analyzed public attitudes with a limited number of respondents and fragmentary opinion polls. In order to supplement this point, this study suggests a big data analyzing method with K-LIWC (Korean-Linguistic Inquiry and Word Count), sentiment and query analysis methods, and investigates public attitudes, positive and negative emotional statements about nuclear energy with the collected data sets of well-known social media and network services in Korea over time. Results show that several events and accidents related to nuclear energy have consistent or temporary effects on the attitude and ratios of the statements, depending on the kind of events and accidents. The presented methodology and the use of big data in relation to the energy industry is suggested as it can be helpful in addressing and exploring public attitudes. Based on the results, implications, limitations, and future research areas are presented.

In the era of COVID-19 pandemic, COVID related keywords, news and SNS data are pouring out. With the help of the data and LDA topic modeling, we can check out what media reports about COVID-19 and vaccines. Also, we can be clear how the public reacts to the vaccine on social media and how this is related with the increasing number of COVID-19 patients. By using sentimental analysis methodology, we can get to know about the different kinds of reports that Korea media send out and get to know what kind of emotions that each media company uses in majority. Through this procedure, we can know the difference between the Korean media and the foreign ones.

The purpose of this study was to objectively explore and discuss the effect of trainer's communication style on rehabilitation ability and rehabilitation satisfaction of elite athletes. we observed the relationship between rehabilitation trainers and injured athletes and found that communication between them plays an important role. In this study, we criticized that most of the studies related to rehabilitation were conducted from the point of view of natural science. The results of this study emphasized that rehabilitation-related research should broadly accept social science positions such as business administration. The main research findings are as follows. As a result of analyzing the relationship between trainer's communication style and rehabilitation ability, first, the trainer's cooperative and professional communication style affects emotional factors of injured players. Second, the trainer's cooperative and controlled communication style affects the cognitive factors of injured players. Third, the trainer's cooperative and professional communication style affects the behavioral factors of injured players. Fourth, the trainer's cooperative and professional communication style affects the rehabilitation satisfaction of injured players. Based on these results, this study was conducted to validate the necessity of discussing the trainer's communication style preference according to the individual background such as the injured player's gender, personality, and injury level, and the classification and composition of communication styles that match Korean culture and sentiment. As suggestions for follow-up research, active sharing of problems with adjacent disciplines such as sports sociology, sports education, and sports marketing, and parallel qualitative research centered on individual cases were suggested
