As the spread of COVID19 has compelled activities in various fields to transform to adapt to the non-face-to-face environment, various activities have either already been transitioned into non-face-to-face methods or been searching for alternative methods to carry out activities in a non-face-to-face manner. However, there are apparent limits in handling this transition with the pre-existing digital technology. Ironically, said limitations are more apparent in the UX design field that has thus far emphasized resolutions based on digital technology. The reason for this stems from the nature of UX design which strongly emphasizes the importance of collaboration. Especially, in the field of UX design, problems are expected to surface under areas of communication and collaboration in workshops, which are productive means of collecting the ideas of interested parties and coming up with other new ideas. Based on the aforementioned rise of necessity, this study aims to assess the characteristics of workshops in the field of UX design and suggest an effective method of transitioning UX workshops into a non-face-to-face environment. Along the line of this process, this study has created a standard process in regards to design workshops with active creation, suggestion, and acceptance of ideas, among the various types of workshops defined by the Nielsen Norman Group. This study also developed a framework consisting of non-face-to-face workshops by combining with the standard process the methodologies of workshop activation and non-face-to-face services meant for communication and designing activities, and confirmed the adaptability and the effectiveness of said transition against various types of workshops. Application of the results of this study is expected to effectively lead the transition into the non-face-to-face environment and improve the collaborative efforts of the interested parties via workshops.

This study is a qualitative study in which a focus group interview is applied to explore nursing students' perception of blended learning. 21 students in the 4th grade of nursing department were divided into 4 groups to collect data through interviews and content analysis was conducted. As a result of the study, it was categorized into four topics: 'Application and operation that are not thoroughly prepared', 'Loss of direction and departure from learning', 'One-way listening', and 'Convenience'. Students were satisfied with blended learning which is free from time and space constraints and repetitive, but felt inadequacy and unsatisfactoriness about quality of online contents, system, and preparation for applying blended learning. In order to apply blended learning in the future nursing classes, high-quality online content should be developed based on the effective design of online and offline classes considering the curriculum, and a systematic, administrative, financial, and institutional foundation to support online course should be prepared. In addition, a support system should be created to guide students' self-directed learning activities in online classes of blended learning.

The purpose of this paper is to examine the effects of practicing Hatha Yoga on the elderly. I have focused on the changes in subjective pain and a feeling of helplessness in their daily lives of elderly people over 65 who are suffering from chronic back pain. We looked at both men and women over 65, who were not working during the period, all of whom had been experiencing back pain over 6 months. All the subjects have never practiced Hatha Yoga or any other specialized and/or systematic workouts at that time. Among them, the men and women over age 65 with chronic back pain were selected as a group and practiced Hatha Yoga three times a week for eight weeks. In conclusion, the study proves that Hatha Yoga is an effective way for the old over 65 with chronic back pain by acquiring muscular strength and flexibility at the same time.

This study aims to investigate the effects of literary texts as a teaching tool to enhance college students' English communicative competence both in linguistic aspects and affective ones. The control group used only the course book as study material, whereas the target group read four short stories along with it and engaged in a series of follow-up tasks. To measure their English competence, the researcher had both groups take a pre-test and a post-test, compared the results, and analyzed the data using SPSS. The study indicates that though the target students' post-test scores increased, the result failed in reaching a significant level. Nevertheless, reading and discussing literature facilitated the target students' affective aspects of communication. This article points out some other limitations of utilizing literary texts in language teaching and suggests the need for further research to deal with the issues.

The purpose of this study is to compare the difference between quadriceps strength and endurance on the degree of elasticity of convergent kinesio taping. Twenty-eight normal adults who voluntarily participated in this study were randomly assigned among 4 groups, that is, group without tape, group with tape elasticity of 0 %, group with tape elasticity of 25 %, or group with tape elasticity of 50 %. Quadriceps strength and endurance were measured using CSMI. Strength among the groups was significantly different (p<.001), and the greater the elasticity of the tape, the greater the muscle strength. However, endurance was't significantly different among the groups (p>.05). These findings suggest that convergent kinesio taping elasticity with 25% and 50% is effective for quadriceps strength in physical activity.

In this paper, a study was conducted to understand how students' attitudes and tendencies toward reading affect the newly emerging coding education. Relevant data were collected by dividing it into three areas (reading, coding, and leisure). In the reading area, data on preference books, preferred types of reading and etc were collected. In the coding area, prior learning of coding, main tasks using a computer, time used for learning and etc were collected. In the leisure area, main leisure activities and hours of spent leisure time per one week were collected. Using the collected data, we classified and analyzed the data based on the preferred reading method to identify the problems of non-major students who have difficulties in coding education. In coding education, the excerpts reading student group showed the best achievement (average 60.1), and the extensive reading group showed the lowest achievement (average 48.4). The students who read extensively spent more time in coding study than the group of students who preferred other reading methods, but showed the lowest achievement.

This study explored a mathematical modeling flow and the effect of interactions among students and between a student and Excel on modeling in a small group modeling environment with Excel. This is a case study of three 8th graders' modeling activity using Excel during their extra lessons. The conclusions drawn from this study are as follows: First, small group modeling using Excel was formed by formulating 4∼10 modeling cycles in each task. Students mainly formed tables and graphs and refined and simplified these models. Second, students mainly formed tables, algebraic formulas and graphs and refined tables considering each variable in detail by obtaining new data with inserting rows. In tables, students mainly explored many expected cases by changing the values of the parameters. In Graphs, students mainly identified a solution or confirmed the solution founded in a table. Meanwhile, students sometimes constructed graphs without a purpose and explored the problem situations by graphs mainly as related with searching a solution, identifying solutions that are found in the tables. Thus, the teacher's intervention is needed to help students use diverse representations properly in problem situations and explore floatingly and interactively using multi-representations that are connected numerically, symbolically and graphically. Sometimes students also perform unnecessary activities in producing data by dragging, searching a solution by 'trial and error' and exploring 'what if' modeling. It is considered that these unnecessary activities were caused by over-reliance on the Excel environment. Thus, the teacher's intervention is needed to complement the Excel environment and the paper-and-pencil environment properly.

Objective : This study was designed to determine the effects of sensory integration group therapy with regard to the sensory processing, peer interactions, and task performance, and whether they continue. Methods : Twelve children aged 7 to 13 years enrolled in this study for 60 minutes per session, three times a week for 8 weeks. Sensory integration group therapy consisted of a total of 24 activities that included sensory processing, play skills, and interaction with peers. Short Sensory Profile was used to select subjects. In order to measure the outcome, we used the Short Sensory Profile, Penn Interactive Peer Play Scale and Canadian Occupational Performance Measure at pre, post, and follow-up evaluations. The results were analyzed by means of repeated measures analysis, and the pre-test, post-test, and follow-up tests were compared using the Wilcoxon matched-pair signed rank test. Results : After sensory integration group therapy, sensory processing, peer interaction, and task performance significantly improved(p<.05). In addition, we confirmed that the effects of treatment were maintained in the 4 weeks follow-up test. Conclusion : Sensory integration group therapy is an effective way of mediating effects not only by improving sensory processing skills, but also by providing imitation and training in groups for children in need of peer interaction and linking them to daily life.

This study conducted K-POP cover dance for female marriage immigrants, and analyzed the effects of Self-esteem and social support on acculturation stress and depression to provide basic data for improving social relationships and promoting mental health of female marriage immigrants. Female marriage immigrants in their 20s and 30s were recruited, and 25 people each were randomly assigned to a high Self-esteem and social support group (HSS) and a low Self-esteem & social support group (LSS) according to the Self-esteem and social support of the pre-test, a total of 3 surveys were conducted, pre-test, after 6 weeks, after 12 weeks. The Self-esteem of female marriage immigrants following K-POP cover dance(60 minutes, 3 times a week, for 12 weeks) participation improved as the participation period in both HSS and LSS groups increased, and the LSS group improved significantly after 6 weeks. Social support decreased after 6 weeks in HSS and 12 weeks in LSS, The acculturation stress continued to decrease after 6 weeks and after 12 weeks in both HSS and LSS, and the LSS group decreased more significantly. Depression in both HSS and LSS groups decreased as the participation period increased, and the LSS group decreased significantly after 6 weeks. K-POP cover dance is thought to be an effective leisure activity program for female marriage immigrants to improve Self-esteem and social support, and to reduce acculturation stress and depression.
