  • Due to tough competition among social network services, technological specification alone could not be an adoption factor by the users. Instead, emotional factors such as a brand image and feeling towards an SNS brand became important factors in service differentiation. This study examined Korean young users perception of brand personalities of three social network services, Facebook, Kakao Story, and Band. It also analyzed the influence of the perception of brand personality, brand-self-image congruence, and brand affect on brand recommendation to others. The authors conducted a survey of Korean college students. The results indicate that SNS users perceived three SNS's brand personalities differently, and the positive perception of an SNS service has a positive effect on brand recommendation. Brand personality, brand-self-image congruence, and brand affect combined determine brand recommendation. When the brand personality variable is statistically controlled, brand affect has strong effect on brand recommendation.

  • This study is an analysis of the user experience of online hobby class platform, focusing on the art field, which reduces space-time constraints and lowers accessibility. To this end, I investigated cases of online hobby class platforms and conducted surveys to measure user experience for university students and office workers in their 20s and 30s in Korea. As a result, we found the gap between the elements satisfying the user experience and the current domestic service, and suggested a way to narrow it down. This study is meaningful in that it proposed ways to further promote online hobby class platforms in the future leisure culture market. It is hoped that this study will be used as data on the user experience of future online hobby platforms and further help discuss practical activation measures.

  • Purpose: This study aims to examine the effects of auriculotherapy on reducing signs of dry eye syndrome. Methods: This study is based on a pretest-posttest nonequivalent control group design. The participants who scored higher than 13 on the Ocular Surface Disease Index (OSDI) were divided randomly into two groups, the experimental group (n=45) and the control group (n=44). Auriculotherapy was performed by researchers for 2 weeks. For the experimental group, seed stickers were applied to the eye, liver, shenmen, and tubercle point of their ears. The pretest and the posttest included the same questionnaires of the OSDI as well as the Visual Function Questionnaire (NEI-VFQ25) and the eye fatigue. Data were analyzed by descriptive statistics, $x^2$ test, t-test and paired t-test, using SAS 20.0 program. Results: The difference in the OSDI's scores showed a significant decrease between the pretest and the posttest (t=-4.12, p<.001) in the experimental group. No significant difference was found in the NEI-VFQ25 (t=-0.10, p=.921, t=-0.91 p=.374). However, the experimental group showed a significant decrease in eye fatigue (t=5.78, p<.001), whereas the control group showed no difference (t=1.38, p=.18). Conclusion: Auriculotherapy can be used effectively on relieving the symptoms of dry eye syndrome and eye fatigue. However, the quality of life related to eyes was not improved by auriculotherapy.

  • Purpose : The purpose of this study was to investigate the effect of single limb stance exercise according to the support surface on dynamic balance ability and abdominal muscle thickness. Methods : We recruited 28 healthy subjects in this study. Subjects were assigned to 2 groups by matching method. The control group was 5 males and 9 females, and single limb stance exercise was performed on the stable support surface. The experimental group consisted of 6 males and 8 females, and trained to stand on the unstable support. During the single limb stance exercise, the dominant foot was set as the foot that appeared numerically through the exercise of the dynamic balance meter (Biorescue). Single limb stance exercise along the supporting surface was maintained for 15 seconds and then rested for 15 seconds. It was repeated 5 times. Particularly, the balance exercise on the unstable support surface was sufficiently practiced. Independent t test was performed for comparison between groups. Paired t test was performed to compare before and after each group. Results : There was no difference between the control group and the experimental group in the comparison of dynamic balance ability (p>.05). However, there were significant differences before and after exercise in both the control and experimental groups (p<.05). Similarly, in the comparison of abdominal muscle thickness, there was a significant difference within each group, especially internal oblique and transverse abdominis (p<.05), and no difference between groups (p>.05). Conclusion : Based on these results, although there was no difference between the groups, in the experimental group, numerical increase in dynamic balance ability and abdominal muscle thickness was confirmed. Therefore, single limb stance exercise on the unstable support surfaces activates core muscles and has a positive effect on dynamic balancing ability.

  • The purpose of this study was to accurately measure the load generated on the leg according to the position of the sling strap supporting the leg during the sling bridge exercise for improvement of life care. Ten Healthy university students participated in two trials: knee bridge exercise and ankle bridge exercise in supine position. The loads transmitted to the knees and ankles were measured when a bridge exercise was performed with a sling strap on both knees and ankles. As a result of the study, it was confirmed that the load of sling bridge exercise with both knees supported was statistically greater than the load of sling bridge exercise with both ankles supported(p<.01). On the other hand, there was no statistically significant difference in the load between both knees and both ankles (p>.05). Therefore this study is meaningful in that it objectively measured the load on the leg during sling bridge exercise, and is thought to be helpful in setting exercise intensity during sling exercise.

  • In an acceleration of 'untact' society during the COVID-19 pandemic, video conferencing platforms have been provided to connect the isolated and to overcome the limit of having interpersonal relationships. While these services brought a great deal of benefits, they also increased the number of people who suffer from additional fatigue from video conferencing. This study, thus, aimed to identify the factors of using video conferencing services and further to examine the relationship between the factors and the users' overall fatigue. Through focus-group interviews and survey, four main factors of fatigue (restriction from untact communication, difficulty of use, background set-ups, discomfort from excessive attention) were identified. This study also found the positive relationships of restriction from untact communication and background set-ups on the users' overall fatigue. The results does not only provide implication on defining new fatigue factors from young generations but also help practitioners and service providers to improve the deficits of services that the real users currently experience.

  • The purpose of this study was to investigate the nutrient intake status of university students in Chuncheon area (175 males and 131 females). This study was conducted by employing a self-administered questionnaire. Dietary assessment was measured by a 24-h recall method. The average height and weight of male students were $175.2{\pm}6.2cm$ and $68.2{\pm}9.9kg$, respectively. For female students, average values were $161.7{\pm}5.2cm$ and $55.1{\pm}6.5kg$, respectively. The mean BMIs for both male and female students were 22.2 and 21.1, respectively. In both male and female students, the rate of skipping breakfast was high. Daily averages for energy, carbohydrates, protein, and fat intakes in male students were significantly higher than those of female students (P<0.001). For male students, protein, vitamin B1, P, Fe, and Na were above recommended nutrient intake and adequate intake, whereas for female students, they were protein, vitamin A, P, and Na. For male students, nutrient intakes for Ca, vitamin $B_2$, vitamin C, and vitamin $B_6$ were below the estimated average requirement (EAR) by at least 50% or more, whereas for female students, they were vitamin C, Fe, vitamin $B_6$, vitamin $B_2$, niacin, folate, and Ca. Ca was alarmingly low, with more than 75% of both male and female students showing levels below the EAR. Therefore, it is important that nutritional education be facilitated for college students to take responsibility of their own health through learning about nutrient intake as well as developing positive eating habits.

  • The study aims to design an integrated remote controller, which is an increasingly essential device in the home, for more convenient use. For this purpose, an alternative user interface (UI) design was developed by applying the user interface system of a popular existing product to an integrated remote control highly usable and easy to learn for domestic use, and the usability was evaluated. For the existing popular product, a cellular phone was selected, the operation method of which is similar to the stick-type integrated remote control for which the user interface design was to be developed in this research. Common characteristics of the UI of the selected cellular phone were derived and the characteristics were applied as much as possible to the design of a stick-type integrated remote control. The prototype of the alternative design, which was simulated with Flash, went through two pilot tests for further improvement before making the final experimental prototype. Based on the results, prototype buttons that improved the feeling of use in terms of physical operation and feedback were made, and the usability of the new UI design of a stick-type integrated remote control for domestic use were evaluated with 41 university students in their 20s. According to the results of the experiment, the newly designed stick-type integrated remote control based on the UI of an existing product may improve the usability of remote controls and the outcome of this study is expected to provide a good model for R&D of new UI designs of stick-type integrated remote controls for domestic use.

  • A study was conducted on the effects of improving concentration by obscuring the peripheral vision using a blindfold that only covers the left and right sides of the field of view. The blindfold was trapezoidal in shape (5 × 4.8 cm in length and width) and was fixed to the left and right sides of the glasses with fixing clips. The material was a black-colored polypropylene (PP) and weighed 2.3 g including the clip. Qualitative and quantitative evaluations were performed on 50 healthy college students during the 15 days of using a blindfold. The qualitative analysis was performed utilizing a questionnaire regarding the improvement of concentration and the structure of the blindfold. EEG was measured while watching a learning video that required attention for quantitative analysis, and signal power and ERD/S analyses were performed for the mid β band (15-20 Hz) at the F4 position, which was the frontal lobe. The results showed that 40 of the 50 people reported improved concentration when they wore a vision shield, and 80% of the total subjects found it to be effective. From the quantitative evaluation, the ERS peak (p = 0.023) and the ERD + ERS peak value showed a significant difference (p = 0.017). In conclusion, concentration still improved even if only the left and right visual fields were used. Thus, it is expected that blindfolding could be used in various environments that require concentration.
