Recent advances in mobile devices and development of various mobile applications dealing with private information of users made user authentication in mobile devices a very important issue. This paper presents a new user authentication method based on touch screen interfaces. This method uses for authentication the PIN digits as well as the exact locations the user touches to input these digits. Our method is fully compatible with the regular PIN entry method which uses numeric keypads, and it provides better usability than the behavioral biometric schemes because its PIN registration process is much simpler. According to our experiments, our method guarantees EERs of 12.8%, 8.3%, and 9.3% for 4-digit PINs, 6-digit PINs, and 11-digit cell phone numbers, respectively, under the extremely conservative assumption that all users have the same PIN digits and cell phone numbers. Thus we can guarantee much higher performance in identification functionality by applying this result to a more practical situation where every user uses distinct PIN and sell phone number. Finally, our method is far more secure than the regular PIN entry method, which is verified by our experiments where attackers are required to recover a PIN after observing the PIN entry processes of the regular PIN and our method under the same level of security parameters.

Background/Aims There has been major progress in our understanding of the irritable bowel syndrome (IBS), and novel treatment classes have emerged. The Rome IV guidelines were published in 2016 and together with the growing body of Asian data on IBS, we felt it is timely to update the Asian IBS Consensus. Methods Key opinion leaders from Asian countries were organized into 4 teams to review 4 themes: symptoms and epidemiology, pathophysiology, diagnosis and investigations, and lifestyle modifications and treatments. The consensus development process was carried out by using a modified Delphi method. Results Thirty-seven statements were developed. Asian data substantiate the current global viewpoint that IBS is a disorder of gut-brain interaction. Socio-cultural and environmental factors in Asia appear to influence the greater overlap between IBS and upper gastrointestinal symptoms. New classes of treatments comprising low fermentable oligo-, di-, monosacharides, and polyols diet, probiotics, non-absorbable antibiotics, and secretagogues have good evidence base for their efficacy. Conclusions Our consensus is that all patients with functional gastrointestinal disorders should be evaluated comprehensively with a view to holistic management. Physicians should be encouraged to take a positive attitude to the treatment outcomes for IBS patients.

During the pandemic, social distancing continued for a long period of time, and as a result, this situation raised the possibility of the online space as a place for serious social relationships. In particular, metaverse platforms are adding to the reality of virtual space by expanding their functions so that users can provide various online events and have a variety of new experiences. This study attempted to examine the social relationship between reality and the metaverse according to social inclinations and behavior patterns. As a result of this study, the group with a high sense of inferiority in their usual relationship and the group with low satisfaction with their usual social interaction felt high discomfort at a similar level in both real and metaverse relationships. The group with the opposite inclination felt more uncomfortable in the metaverse relationship than in reality. In addition, whether the behavior patterns in the metaverse and in reality were different or same did not significantly affect the difference in attidudes between the metaverse and reality. In the case of group with different behavior patterns, however, if they were satisfied with how they look in the metaverse, their intimacy with social relationships was also high. This results implicate that we need to make an special effort for the development of social relationships in the metaverse era.

The purpose of this study is to develop and evaluate a dietary education program to improve the caring ability and multicultural acceptance of middle school students. Based on the instructional system design of ADDIE model, the dietary education program was developed to contain five sessions including four theoretical lectures and one lab session. Visual thinking technique was used to train students to express their thoughts and emotion by writing and drawing. The dietary education program was conducted for four weeks (from November 19 to December 14, 2018) at a middle school located in Seoul on a total of 69 middle school students, out of which 34 were assigned to an experimental group and 35 were assigned to a control group. Separate paired t-test were conducted for the experimental group and the control group, respectively, to determine the changes in caring ability and multicultural acceptance scores before and after the dietary education. There were significant increases in caring ability (dietary-, emotional-, behavioral- and cognitive caring) and multicultural acceptance (diversity, relationship and universality) scores among the experimental group after the dietary program. However, no differences were observed among the control group. The results indicate that the dietary education program can be an effective tool to improve caring ability and multicultural acceptance of middle school students.

The purpose of this study was to understand the parents' perceptions of the distance learning provided to students with disabilities and to explore the demands for educational support. A survey was conducted on a total of 2,392 parents of school-age children with disabilities. The survey questions were largely divided into the learning support to prevent educational gap, support for behavioral and psychological difficulties, and care support for educational welfare. As a result of the study, it was found that face-to-face education in schools was the most important to prevent the educational gap between students with disabilities, and counseling on distance learning methods and strategies suitable for the characteristics of the disabled in connection with the Special Education Support Center was the most necessary. As a learning support method for distance learning for students with disabilities, there was a high demand for individual learning support through preparatory special education teachers, and it was necessary to secure enough learning aids and assistive technology devices to be used appropriately when needed. In addition, psychological counseling and educational support for students with disabilities were requested, and there were demands for development of care programs suitable for the characteristics of the disabled and assignment of dedicated personnel. Based on the results of this study, this study suggested implications for students with disabilities to bridge the learning gap and provide educational support due to distance learning.

The present study was conducted to develop and validate a psychological scale that measures individuals' attitude toward unification of Korea (ATU-K). Building on major theoretical perspectives on the structure of attitude and the attitude-behavior link, we specified two sub-components each representing the cognitive and the affective dimension of people's attitude toward unification. In a survey that involved a stratified sample of Korean adults (N = 1,500), we found strong evidence showing the construct validity of the ATU-K scale. We also found evidence for the convergent and discriminant validity of the scale. In a second survey involving another stratified sample of 1,500 Korean adults, we found the utility of the ATU-K scale in predicting people's intention to engage in unification-oriented behaviors (personal/collective). We also found that the ATU-K scale fares better in predicting the intention vis-a-vis the other measures of unification-related beliefs reported in previous research. We discuss implications of our findings and directions for future research.

The purpose of this study tries to show the effectiveness of integrated theater education for low-grade students who lack social skills with the direction of art education based on 'theatrical and educational theater' and 'theater therapy' in the revised curriculum in 2015. To do this, the researcher organized a theater camp organized by the social, cultural and arts education institute in Seoul for a total of 12 low-grade elementary school students for four weeks, and had a presentation session. In addition, the researcher observed the behavioral changes of the participating children to verify the social development of the theater education and after the conclusion, the final results were obtained through the in-depth interviews of the participants' parents and teachers. As a result, it was found that Social Skills Rating System(SSRS)' test, teachers' observation logs, interviews, and responses of participating children, which are the main subjects of this activity, had a great effect on improving their sociality and relationship. Therefore, the researcher tried to prove through this paper that theater education is effective in enhancing social skills as creative, personality and convergence education in preparation for the 4th industrial era and that it is important to solve communication problems such as the absence of human relationships.

When consumers choose healthy foods, they base their buying decisions on health-related food labeling and quality assessment of taste, health, and price. Moreover, both purchase experience and opinions of family and friends affect consumer choices. Focusing on these points, this study examined the effects of health-related food labeling on consumer choices by adding two variables-quality assessment of taste, health, and price and purchase experience-to the model of the theory of planned behavior. We also used structural equation modeling to test our hypotheses. In the study, health-related food labeling includes organic labeling, nutrient claims, and food additive labeling. We conducted a mail survey among 300 married women who buy cheese slices for their children more than once a month. It was discovered that health-related food labeling positively affected the level of quality assessment of taste, health, and price, and consequently led to positive attitudes and purchase intentions. Particularly, health-related food labeling positively influenced attitude toward using products without assessing the quality of taste, health, and price. The level of quality assessment of price positively affected attitude toward using and purchasing products, and purchase experience positively affected attitude toward using and purchasing products, and purchase intentions. The relationship between attitude to purchasing products and purchase intentions was the most positive, and the relationship between perceived behavioral control and purchase intentions was not significant. Overall, this study essentially contributes to the development of a theoretical framework of food labeling and consumer choices, which includes quality assessment of taste, health, and price and purchase experience, by using the theory of planned behavior.
