Purpose: The purpose of this study was to determine the effects of electromyography (EMG)-biofeedback based closed kinetic chain exercise (CKCE) on quadriceps muscle activity and dynamic balance ability in patellofemoral pain syndrome (PFPS). Methods: Thirty subjects with PFPS were included and they were divided into EMG-biofeedback using CKCE (Group Ⅰ) and squat exercise using CKCE (Group Ⅱ), each group consisted of 15 patients. Group Ⅰ and Group Ⅱ was performed by the patients for three times a week, for six weeks. sEMG was used to measure quadriceps muscle activity and star excursion balance test (SEBT) was used to measure dynamic balance ability. Results: According to the results of the comparisons between the groups, after intervention, quadriceps muscle activity and dynamic balance ability were significantly higher in Group Ⅰ than in the Group Ⅱ. Conclusion: Findings of this study suggest that EMG-biofeedback using CKCE that provides real-time biofeedback information on muscle contraction may have a beneficial effect on selective muscle strength of vastus medialis oblique muscle and dynamic balance ability in PFPS.

Through in-depth interviews with 12 insiders of campus media in each region, this study sought to find out how campus press responds in today’s media environment and how to revitalize campus press. Campus press insiders agreed that college students’ use of campus press is significantly lower. Campus press student reporters try various contents, use online platforms, and produce in various formats to increase the use of campus in the university community. The organizational situation of campus press could be classified into active, sustained, stagnant, and restorative types. Student reporters in the campus press complain of being overloaded with work that makes it difficult for them to combine their works with their studies. Some campus press can recruit student reporters properly because of school’s support and a large pool of aspiring journalists. On the other hand, some campus press have fewer applicants for media jobs due to skepticism about the vision and employment conditions of local media, which affects the recruitment and operation of student reporters. In order to revitalize the campus press, it is necessary to try to break away from the stereotypical content and format and expand the participation and feedback of student users, but it can also be suggested to improve the work efficiency of the campus press, provide sufficient compensation, and review the operation of the secretary system.

This study investigated the process and types of local university students using local news. Local college students did not have easy access to local news. Because the media mainly used by these generations moved from television to smartphones and digital platforms. But local media did not provide accessibility in these media environments. In addition, as their locality has faded compared to the past generation, they did not use local news. And they had a prejudice against local news. However, after experiencing and observing local news, their perception of local news has changed. They thought that the information provided by local news would be helpful to them. As for the quality of local news, compared to national news, only the subjects and categories covered were different, but they did not feel a big difference. In addition, it was recognized that local news was essential to the region. The news use types of local university students were classified as ‘social level approach type’, ‘administrative boundary approach type’, ‘interest-oriented approach type’, and ‘indifference type’. In order for local university students to use local news, this study suggests easy access to local news, provision of socially universal content and content closely related to the local, and opening of local journalism courses at local universities.
