In the era of the 4th industrial revolution, virtual reality (VR) technology is emerging as an optimized tool for learning foreign languages in light of current circumstances requiring non-face-to-face education. The combination of artificial intelligence (AI) and VR has increased the demand for VR-based foreign language learning contents. VR enables learners to learn new languages and experience different cultures through immersive experiences by teleporting the users to the country where a target language is spoken. It also provides dynamic and proactive learning through various interactions. Thus, this study examines the effects of VR in learning foreign languages and investigates the types and characteristics of VR-based foreign language learning contents currently in use. In addition, this study suggests major issues to be considered for the contents and technical composition of the contents by identifying what should be improved and benchmarked for developing VR-based French learning contents.

The purpose of this study was to examine the effect of yoga exercise within the color lighting environment on the senior citizens’ exercise flow and the electroencephalogram (EEG). In this study, a yoga exercise program was conducted once a week for 19 senior citizens living in Yeonsu-gu, Incheon, who voluntarily agreed to participate in the study. As for the experimental design of the study, utilizing a within-subject design, it was conducted by using a randomized crossover trial based on the 2 types of experiments such as by treating them with the color lighting environment and treating them with the white lighting environment for the lighting environment for the yoga participants. A one week interval was placed so as not to influence the measurement results during the measurement. As for the EEG test, measurement was taken by attaching 2 channels to the frontal lobe on the right and left, and as for the exercise flow, the exercise flow measurement consisted of the 5 sub factors of Clear Goals, Sense of Control, Loss of Self-Consciousness, Transformation of Time, and Autotelic Experience were used. The EEG test was conducted before and after the yoga exercise, and the exercise flow questionnaire was required to be prepared after the yoga exercise. The results of this study have demonstrated significant changes in the Theta wave, Alpha wave, and the Gamma wave following the exercise flow in the color lighting environment. To the contrary, the Low-Beta waves, Middle-Beta waves, and the High-Beta waves demonstrated no significant changes. Hence, it can be concluded that the exercise flow following the color lighting environment of the yoga participating senior citizens increases the Alpha waves and the Theta waves, while reducing the Gamma waves. Such results of this study are significant in that they present the basic data on the physiological responses of the yoga studies for which color lighting is applied in Korea in the future.

The present study aimed to investigate the oral health of the elderly since the beginning of the COVID-19 pandemic and to examine the associated problems in depth. The actual condition of the oral hygiene management of the elderly was investigated by interviewing care workers who have been caring for the elderly for more than three years in nursing homes, nursing hospitals, and home-based care service centers in the Seoul and Gyeonggi areas. Three categories were identified based on the results of in-depth interviews: oral health of the elderly, education of care workers for oral health care of the elderly, and changes following the COVID-19 pandemic. The main topics included the oral condition of the elderly, oral healthcare for the elderly, differences based on facilities and guardians, need for support, current status of education for oral healthcare for the elderly, willingness to participate in education for oral healthcare for the elderly, desired type of education, depression and atrophy in the elderly, anxiety of care workers, and difficulties associated with oral health problems in the elderly. Based on the above results, there was no significant difference in the oral health care methods of the elderly since the COVID-19 pandemic, but situations in which it is difficult to receive treatment smoothly when a health or oral health problem occurred were having a negative effect on the health of the elderly.
