The present study have investigated the effect of the characteristics of stereoscopic images and viewing environment on visual fatigue. We manipulated the speed of stereo images with motion-in-depth and viewing distance, which were used as representative variables of the characteristics of stereo image and viewing environment, respectively. Visual fatigue was evaluated with use of a subjective questionnaire which is consisting of 5 different and independent factors: "Eye pain", "Visual stress," "Nauseousness", "Body stiffness", and "Blurriness". In general, when viewing time increased from 10 minutes to 20 and 40 minutes, observers felt severe visual fatigue. Among other factors, only the factor score of "Nauseousness" was significantly increased as the speed of object moving in depth became faster. When viewing distance was increased, the score of "Blurriness" was decreased. These results suggest that different kind of the visual fatigue might be induced depending on characteristics of the stereo images and viewing environment.

The touchscreen device is now commonly found in the form of mobile phones, tablet PCs, and other devices. Varied physical and visual experiences can be experienced through touchscreens. This study intended to explore how the physical and visual experiences provided by the touchscreen would affect people through their existing associations of behavior-attitude. Previous studies have found that certain behaviors affect attitudes. In particular, the approach-avoidance behavior has been noted to influence both social and personal attitudes. It was thus deemed necessary to ascertain the approach-avoidance effect exerted by touchscreens on the attitudes of users as the technology is widely used today. Experiment 1 provided an approach-avoidance experience via a touchscreen and demonstrated that touchscreen-based approach-avoidance dragging behavior on the touchscreen can affect a user's preference and purchase intent. It was found that a product that had been approached showed both higher preference and higher purchase intent than a product that had been avoided. Experiment 2 investigated whether a similar effect would occur when only the visual experience of approach-avoidance was provided. The outcome proved that products that had been visually approached had higher scores than products that had been avoided, both in terms of preference and purchase intent. The movement of the arm on the touchscreen (Experiment 1) and the visual perception of the approach-avoidance experience (Experiment 2) were both shown to influence participants' attitudes toward products. The results of this study suggest that the behavior and perception of users may be an important factor in designing touchscreen interfaces for online shopping.

In the era of the 4th Industrial Revolution, artificial intelligence (AI) has become one of the core technologies in terms of the business strategy among information technology companies. Both international and domestic major portal companies are launching AI search services. These AI search services utilize voice, images, and other unstructured data to provide different experiences from existing text-based search services. An unfamiliar experience is a factor that can hinder the usability of the service. Therefore, the usability testing of the AI search services is necessary. This study examines the usability of the AI search service on the Naver App 8.9.3 beta version by comparing it with the search services of the current Naver App and targets 30 people in their 20s and 30s, who have experience using Naver apps. The usability of Smart Lens, Smart Voice, Smart Around, and AiRS, which are the Naver App beta versions of their artificial intelligence search service, is evaluated and statistically significant usability changes are revealed. Smart Lens, Smart Voice, and Smart Around exhibited positive changes, whereas AiRS exhibited negative changes in terms of usability. This study evaluates the change in usability according to the application of the artificial intelligence search services and investigates the correlation between the evaluation factors. The obtained data are expected to be useful for the usability evaluation of services that use AI.

This study investigated the association between depression and oral health and the factors influencing depression in adults. Data on 13,199 people (male 5,793, female 7,406; age ≥19 years old) were extracted from the Korean National Health and Nutrition Examination Survey VIII (KNHANES VIII) (2016~2018) and analyzed using frequency, percentage, an x² test, a T-test, and logistic regression analysis. Depression was defined as either a medical diagnosis or a score ≥10 on Patient Health Questionnaire-9. The probability of depression was found to be statistically different for general characteristics, such as gender, age, school grade, income, and drinking. The logistic regression analysis showed that the independent variables, general health awareness (OR=9.094, 95% CI 7.139~11.585) and oral health awareness (OR=1.936, 95% CI 1.465~2.560), were associated with depression, and speaking discomfort, chewing discomfort, oral pain (within 1 year), and prosthesis were found to increase depression probability. The depression probability was also was found to significantly increase by 1.81 times if brushing frequency was less that once a day, if people used dental floss (OR=1.42), and had to have an oral examination (OR=1.31). These results indicated that oral health and oral health behaviors are associated with the depression, with the influencing factors having oral health and behavior-related characteristics. Therefore, proper oral health and oral health risk factor behavior management programs should be developed to assist in reducing depression.

The weight of an object is an important research topic in terms of sense, and objects have size-weight, color-weight, and material-weight illusions due to the influence of size, color, and material and the weight of the object. Although temperature is a very important environmental factor in our daily life, there is a dearth of studies on how the temperature of an object affects its perceived weight. This study analyzed the effect of an object's temperature on the perceived weight. A stainless steel cup, in which weight and temperature are easily adjustable, was selected as a perceived weight measurement object; 5 temperature levels (0, 9, 20, 40, 70 degrees) and 2 weight levels (250, 400 g) were set. A total of 40 healthy men and women in their 20s participated in the experiment. The weight of the given cup compared to the reference cup was evaluated according to the modulus method. The study revealed that both temperature and weight significantly affected the perceived weight. The effect of temperature on the weight was different depending on the weight of the object. When the cup's weight was small (250 g), the temperature of the cup did not affect the weight. However, the perceived weight of a large cup (400 g) increased at a low temperature. This result suggests that the effect of temperature on the weight of an object depends on the size-weight illusion.

This study aims to examine whether emotional clarity predicts low levels of social interaction anxiety among senior citizens and to verify whether self-esteem and self-efficacy play a critical role as mediators between them. An online survey measuring emotional clarity, social interaction anxiety, self-esteem, and self-efficacy was conducted with 217 Korean senior citizens. The analysis revealed that emotional clarity in old age predicted lower social interaction anxiety. Besides, self-esteem mediated the relationship between emotional clarity and social interaction anxiety, while self-efficacy did not produce consistent results. That is, recognizing one's emotions increases one's self-esteem, which reduces social interaction anxiety, but this mediating effect could not be confirmed through self-efficacy. This result emphasizes that recognizing one's emotions in old age is an important factor in facilitating interaction with others, and shows that individuals can be comfortable in relational situations because emotional clarity increases one's self-esteem. Finally, the implications of this study and the future direction of this research area were discussed.

Recently, interest in and demand for sensors that recognize physical activity and their products are increasing. In particular, the development of wearable materials that are flexible, stretchable, and able to detect the user's biological signals is drawing attention. In this study, an experiment was conducted to improve the dip-coating efficiency of a single-walled carbon nanotube dispersion solution after fine holes were made in a hydrophobic material with a micro needle. In this study, dip-coating was performed with a material that was not penetrated, and comparative analysis was performed. The electrical conductivity of the sensor was measured when the sensor was stretched using a strain universal testing machine (Dacell Co. Ltd., Seoul, Korea) and a multimeter (Keysight Technologies, Santa Rosa, CA, USA) was used to measure resistance. It was found that the electrical conductivity of a sensor that was subjected to needling was at least 16 times better than that of a sensor that was not. In addition, the gauge factor was excellent, relative to the initial resistance of the sensor, so good performance as a sensor could be confirmed. Here, the dip-coating efficiency of hydrophobic materials, which have superior physical properties to hydrophilic materials but are not suitable due to their high surface tension, can be adopted to more effectively detect body movements and manufacture sensors with excellent durability and usability.

The purpose of this study was to determine the effects of resilience on information processing. Thirty-nine male high school students were randomly selected and assigned to one of the three experimental groups: (1) high group (n = 13), (2) middle group (n = 13) and low group (n = 13) according to their resilience scale (KRQ-53) scores. The tasks were simple reaction time, choice reaction time-1, and choice reaction time -2. Electroencephalogram (EEG) was measured at Fp1, Fp2, F3, F4, Fz, Cz and Pz. A 3 × 8 × 4 (groups × areas × times) ANOVA with repeated measures on the last factor was calculated to determine resilience effects on EEG. P300 was analyzed using a 3 × 3 × 8 (groups × tasks × areas) ANOVA. The results showed that the theta waves of the middle group were higher than those of the high and low groups. Second, as a result of analyzing alpha waves, the high group demonstrated higher alpha waves than the middle and low groups. Third, the mid-beta waves of the middle and low groups were higher than those of the high group. Lastly, the result of this study showed that the P300 amplitude of the middle group was higher than that of the high and low groups. These results indicated that the middle group processed cognitive information more efficiently than the other two groups. The findings of this study demonstrated that cognitive information processing ability varies depending on the degree of resilience.

This study is aimed at analyzing the characteristics of adaptation to college life among freshmen of D University by utilizing the DEU-GRIT test. To achieve this, we examined differences in level of college life adaptation according to gender and major, and explored the characteristics of college life adaptation among college freshmen who were clustered based on their level of academic, social, emotional, and career adaptation, which is an important factor in adaptation to college life. Moreover, based on the DEU-GRIT test standards, we also explored the characteristics of their college life adaptation by sorting out low level groups of freshmen with difficulties adapting. The results demonstrated that male students had a higher level of emotional adaptation than female students, and that science and technology majors had higher levels of academic and emotional adaptation than students in the humanities and society majors. Furthermore, a cluster analysis based on 4 factor levels of college life adaptation showed that cluster 1 had a high level of adaptability to all factors, but cluster 3 had a low level of adaptability to all factors. Moreover, while cluster 2 showed a high level of emotional adaptation, cluster 4 showed a low level of emotional adaptation. On the other hand, a lower-standard group of DEU-GRIT tests showed that the level of academic adaptation and social adaptation was higher among female students than among male students. However, the overall level of college life, academic, and emotional adaptation were higher among science and technology students than among those majoring in humanities and social studies. In addition, a cluster analysis based on the level of 4 factors of college life adaptation of lower-standard groups showed that cluster 1 of the lower-standard groups had a high level of emotional adaptation, while cluster 2 of the lower-standard groups had a low level of emotional and career adaptation and a high level of academic and social adaptation. Also, cluster 3 of the lower-standard groups was found to have low levels of all factors, and cluster 4 of the lower-standard groups showed low levels of social and emotional adaptation and high levels of academic and career adaptation. This indicates that, in terms of social and emotional adaptation among freshmen, participation in psychological counseling programs tailored according to gender is necessary and, regarding the major, relative emotional intervention is required due to the high and low expectations of job prospects. In conclusion, the emotional and social adaptation to college life among the lower-level groups is likely to serve as a protective factor for college life adaptation, suggesting that specific intervention should be contemplated.
