The process that one may consciously focuses on necessary stimulation among tremendous amount of stimulation through human sensory systems is called attention in psychology. It is known that the attention can be affected by many factors such as room temperatures, humidity level, etc. In the field of sports science, ice packs are widely used for recovery from exercise fatigue providing fast heat transfer by conduction. However, the effect on attention by so-called iced-pack-cooling has not been tested. This research focuses on the attention levels when one is provided with a special cooling pad on their dorsal and lateral cervices. 40 subjects were divided into four groups and their attention level was evaluated based on the exposure conditions of combinations in reading and light walking with and without the cooling pad. The Frankfruter Aufmerksamkeits-Inventar, FAIR was used to evaluate the attention levels; the performance index, quality index, and continuity index consist of the FAIR test indicating the selectiveness of the attention, correctness of the attention, and maintaining term of the attention, respectively. Analysis of variance was carried out for those variables and post-hoc if applicable. When visual attention is constantly used for reading and studying, application of conductive heat transfer by the cooling pads is significantly helpful for improvement in selectiveness of the attention and maintaining terms of the attention levels. Also, light walking yielded improvement in selectiveness of the attention and maintaining terms of the attention levels; however one should presupposedly consider the loss of reading time.

This study aims to classify the semantic words commonly used to evaluate sound quality and to analyze their differences in reflecting the level of musical stimuli. Participants were thirty-one music majors in their 20s and 30s, with an average of 9.4 years of professional training. Each participant listened to nine pieces of music with variations in texture and instrument type and evaluated them using 18 pairs of semantic words describing sound quality. A factor analysis was conducted to group words influenced by the same latent factor, and a multivariate ANOVA determined the differences in ratings based on texture and instrument type. Radar charts were also drawn based on the identified sets of semantic words. The results showed that four factors were identified, and the word pairs 'soft-hard,' 'dull-sharp,' 'muddy-clean' and 'low-high' showed significant differences based on the level of musical stimuli. The radar charts effectively distinguished the sound quality evaluations for each music. These results indicate that developing Korean semantic words for sound quality evaluation requires a structure different from the previous categories used in Western countries and that linguistic and cultural factors are crucial. This study will provide foundational data for developing a verbal sound quality evaluation framework suited to the Korean context, while reflecting acoustic attributes in music listening.

Media can be considered as a type of play for kids in this new media era. Researches on media content for kids have mainly focused on educational effect or specific features such as design, but a great deal of kids content is created for fun and enjoyment. This study analyzes fun factors of the most popular kids content on Youtube: Kongsuni and Friends, Carrie and Toys, and Pinkfong. The result shows that seven fun factors can be grouped into three categories; 1) Self-determination and independence are related to the media environment; 2) Sensuous vividness, empathy, and physical dynamic are related to the content; 3) Self-expression and social interaction are related to associated activities. This study extends our perspective on kids content by analyzing fun factors in the comprehensive process of media consumption.

Users can experience cybersickness when interacting with virtual reality (VR). The symptoms of cybersickness are similar to those of motion sickness which include eye fatigue, disorientation, and nausea. Despite the longstanding interest of user's discomfort, inconsistent results have been drawn on the underlying mechanisms and solutions of cybersickness. In this study, we propose an integrated view of cybersickness connecting causes of the symptoms, human perception model, and measurements of cybersickness. Cybersickness-related factors of previous research are reorganized into content, hardware, and human factors as well as analyzed in terms of VR fidelity. Also, pros and cons that measure the degree of cybersickness are discussed.

This study investigates the F&B brand choice attributes preferred by Generation Z and the brand experience of the London Bagel Museum, resulting in the following findings. First, in-depth interviews with Generation Z revealed that they consider 'appearance' and 'sociability' to be the most important factors when choosing an F&B brand. The success of the London Bagel Museum can also be attributed to fulfilling these Generation Z F&B brand choice attributes of 'appearance' and 'sociability.' Additionally, 'taste' was found to have the greatest impact on word-of-mouth and revisit intentions. The brand experience of the London Bagel Museum received the highest score in sensory experience, which can be seen as satisfying the visual stimulation that Generation Z, who value 'appearance,' consider important. This was followed by cognitive experience, emotional experience, and behavioral experience, in that order. The significance of this study lies in providing insights for the development of successful F&B brands by elucidating the F&B brand choice attributes of Generation Z and the brand experience of the London Bagel Museum.

Evaluating comfort of illumination environment of building interior is recognizing the degree of glare causing discomfort. Currently, to use the experimental formula for discomfort glare studied abroad it would be not appropriate because each races feel about the degree of glare differently. Therefore, this study aim to make up prediction formula for evaluating discomfort glare reasonably from Koreans' vision and it proceeded with 4 stages as follows: First, after reviewing the existing discomfort glare evaluation formula, I selected experimental variables. Second, I made a mock-up that I can control experimental variables and conditions according to the purpose of this study. Third, 1 conducted discomfort glare evaluation experiment. Finally, compared with UGR evaluation method suggested for Westerner in prior studies. In conclusion, 1) it's proved that discomfort glare is influenced highly by a light source luminance, background luminance and location of testee and the line of vision. 2) In interior discomfort glare experiment whether the glare light source is placed within range of vision or not has more significant influence than the distance between the light source and testee. 3) I compared and analyzed with UGR, the most representative discomfort glare evaluation system and I found there is a little difference in the results. This shows discomfort glare of Koreans and Westerners are different.

VR refers to Virtual Reality technology that allows experiences of virtual contents as if they are real through visual, auditory and other senses. VR is even affecting the news. This greatly shakes the frame of the news. In other words, the conventional way of the new was to watch it with the passive action of seeing pictures, articles and images while VR News offers an active paradigm of experience and participation. This study analyzed the VR news of each press and investigated how VR news is developing. Furthermore, an experimental study was conducted to examine how users actually perceived the VR news. News made using both the existing method and the VR news method were comparatively shown to users who were following the news, and the interview was carried out through questionnaires. The results obtained through the statistics and analysis are as follows. Users made an assessment that they felt the sense of realism in recognition of the VR news while it was still lacking in terms of the unique information delivery that the news performs. However, the intention of using the VR news again was shown to be high, which demonstrated the expectation of users who have experienced the VR news.
