In this study, by selecting specific aptamers that selectively detection on P. gingivalis, the main cause of periodontal disease, and purifying and identifying protein molecules that bind to the selected aptamers, the mechanism of action of P. gingivalis was investigated. A DNA library having 39 random sequences was prepared, and aptamers with specificity for P. gingivalis were selected using the SELEX method, and the nucleotide sequence was analyzed by cloning using PCR2.1 cloning vector. 8 of aptamers with different nucleotide sequences were selected, and modified weston blot was performed using APG-3 among the selected aptamers to identify 11 proteins that act directly, and proteins were analyzed. As a result, a protein that selectively binds to P. gingivalis was isolated and identified. Therefore, aptamer selectively binds and attaches to proteins related to inhibition of sugar metabolism and cell activity of P. gingivalis, suggesting the possibility of a sensor for diagnosis of periodontal disease.

The purpose of this research is to find out the effects of music therapy activities using preferred music on job stress, work engagement and flourishing of reporters in broadcasting company. The study targets 51 reporters in S city, with the experimental group consisting of 20 reporters from A broadcasting company and the control group composed of 31 reporters from A newspaper company. The experimental group voluntarily listened to preferred music at least three times a day for two weeks, while the control group did not perform any activities. For data analysis, the job stress scale, work engagement scale, and flourishing scale scores of each group were collected right before and after the experiment, and the results of the analysis were as follows. First, the experimental group's job stress decreased, and significant score differences were also shown in comparison with the control group. Second, work engagement also increased by a noticeable difference. Third, in the case of flourishing, the after experiment's average value rose slightly, but the difference was not statistically significant. In conclusion, this research offered implications for the need for a music therapy activity program to recover from reporters' job stress circumstances and discussed the need for further research.

This study has verified the consumer effectiveness market influence and relationship with cosmetic purchasing behavior through a covariance model. A female consumer in her 20s or older who had purchased eco cosmetics within the last six months and 300 copies were used for final analysis through panels of online professional research institutes from May 17 to May 30, 2020. As a result of the analysis, functional value, social value, and green consumption value were derived from the consumption value of eco cosmetics. Social value and green consumption value have been shown to have significant impact on consumer effectiveness and market influence but functional value relationships have not been identified. In addition, consumer effectiveness and market influence were found to promote eco cosmetics purchase behavior. Through this study we have identified the importance of perceived environmental issues (consumer effectiveness and market influence) in purchasing eco cosmetics and hope that they will be used as useful data for developing eco products and establishing marketing strategies based on understanding of consumers.

Training, unlike education in holistic perspective, not only affects individual's potential of work competencies such as knowledge and technology, but also affects the job performance in organizational perspective. The effectiveness of training for civil servants who participated in mock jury trial learning of Suwon-si was verified using CIPP model. Participants valued the significance of the process of training rather than the conclusion that draws a certain solution, and based on the comparison and analysis of pre·post evaluations, the educational effect of mock trial training and its utilization at work in the future was higher than before the training, proving its effectiveness. In terms of the implications of training programs in addition to the program planner's evaluation, participant constitution in consideration of sex or employment period is needed for learning interaction among various learners, and information acquisition training on various local issues and conflict situations, as well as the combination of deliberation learning, are needed. in addition, it may be supplemented through customized conflict management raining related to pending projects for the effectiveness of training.

Mindfulness is being used as one of the techniques for emotional regulation. In emotional regulation, mindfulness is considered as an uncontrolled way in that it observes the present experience as it is, rather than attempting to reduce or eliminate negative affective experiences. However, in this study, the purpose of this study is to confirm that mindfulness can affect emotional regulation through perceived control. To confirm this, I verified whether perceived control had a mediating effect on the relationship between mindfulness and difficulty in emotional regulation. For this 366 university students (179 males, 187 females) were surveyed using the scales of mindfulness, perceived control, and difficulty in emotional regulation, and mediation was analysed using Hayes' PROCESS macro. As a result of the analysis, it was found that perceived control had a fully mediating effect in the relationship between mindfulness and emotional regulation difficulties. These results suggest that mindfulness affect emotional regulation through perceived control.
