The purpose of this study was to examine the relationship between major satisfaction and university life adaptation according to the amount of physical activity for university students. This study implement survey to the 201 university students. Descriptive statistics, reliability analysis, one-way ANOVA and pearson's correlation analysis were conducted for data analyses. The results are as follows. First, university students' major satisfaction with the amount of physical activity is statistically significantly higher than that of low-intensity physical activity groups (p<.05). Second, university life adaptation according to the amount of physical activity was found to be statistically significantly higher in high-intensity physical activity groups than in medium-intensity physical activity groups and low-intensity physical activity groups (p<.05). Lastly, according to the relationship between physical activity, major satisfaction, and university life adaptation of university students, male students have a static correlation between physical activity, major satisfaction (general satisfaction), and university life adaptation (personal emotion adaptation) and female students have a static correlation between physical activity and university life adaptation(social adaptation) (p<.05). This study confirmed that the amount of physical activity of university students is related to their major satisfaction and adaptation to university life. Based on this conclusion, it is expected that university students will be able to manage their university life through physical activities.

The purpose of this study was to research the effects of socio-demographic factors and values in each group on satisfaction with life by categorizing the activity types of the elderly into volunteer work and economic activities. The subjects of this study were 60 years an old higher. The questionnaires were categorized depending on activity types and collected. The voluntary work group consisted of 201 people (76 males, 36.8% and 125 females, 62.2%), The economic activity group consisted of 219 people (127 males, 58.0% and 92 females, 42.0%). The SPSS 14.0 Windows program was used to analyze data. Frequency, average, standard deviation, factor analysis, Pearson correlation coefficient, t-test, One-Way ANOVA analysis, and hierarchical multiple linear regression were analyzed. The major findings of this study indicate that the elderly in the voluntary work group have a high collectivism value, higher income earned by performing economic activities, and good cognitive health affected by a high satisfaction with life. From these research results, it was proved that a collectivism value is a common factor that affects satisfaction with life in both of the economic activity group. Those who were older had a traditional collectivism value. The voluntary work group showed a stronger collectivism value and higher satisfaction with life than the economic activity group. Thus, the diverse types of voluntary work should be developed and a systematic system should be established as methods for improving quality of life and satisfaction.

The aim of this study was to compare the effects of a horseback riding simulator, McKenzie, and gym ball exercises on the Korean-Oswestry Disability Index (K-ODI) and muscle activation in people suffering from chronic low back pain. The study was conducted on 30 adults with a K-ODI of 5 or more and chronic low back pain. This experiment was conducted from May to June 2020. They were randomly divided into the horse-riding exercise group (HEG), McKenzie exercise group (MEG), and the gym ball exercise group (GEG). Each group performed the relevant exercises for six weeks, three times a week. The low back pain was measured with K-ODI, and muscle activation was measured with surface electromyography (SEMG). A paired t-test was conducted to verify the change before and after the experiment in the groups, and a one-way ANOVA was conducted to verify the difference between the three groups. The results of the study showed significant differences before and after the experiment. K-ODI and muscle activity improved (p>.05), and significant differences were also found between the groups (p<.05). This study concluded that horse riding and McKenzie exercises could be effective methods for the treatment of pain and to stabilize the lumbar region in patients with chronic low back pain.

This study aims to discuss ways needed to prepare their careers through relations between the personal internal factors perceived by college students in the process of career preparation and the external factors they experience during college life. To this end, the study conducted not only a questionnaire survey of 927 students at K University in Seoul but also hierarchical multiple regression analysis, independent two sample t-test, and one-way ANOVA (analysis of variance). The study set career preparation as a dependent variable, presented research models in four steps, and the explanatory power of each model was statistically significant. According to the findings of the study, both Model 1 and Model 2, gender had a significant impact on career preparation. Also, when self-directedness was added to Model 2, self-directedness had a greater impact on career preparation than gender did. When satisfaction with extracurricular activities was added to Model 3, this factor turned out to be helpful for career preparation. When college immersion, or a sense of belonging to college, was added to Model 4, the higher the sense of belonging students perceived, the more helpful they felt it for their career preparations. This study is expected to be helpful in preparing a policy to support college students' career preparation by grasping the relations between the personal characteristics of college students and career-related activities and college immersion they experience during college life.

The ability to creatively pursue new knowledge and perspectives across various disciplines has established itself as a basic literacy for living in the 21st-century convergence era. With the development of various creative education programs, assessment tools that can objectively and systematically evaluate learners' academic achievement are also required. Therefore, this paper proposed the self assessment, peer assessment, creativity assessment, and reflection tool based on the hyper blended practical model as assessment tools for creative convergence education programs for elementary and secondary school students. The developed assessment tools attempted to develop more completed evaluation methods by modifying two items and deleting four items through validity tests. In addition, the evaluation tool was applied to 596 elementary and secondary school students nationwide, and the application results were analyzed through one-way ANOVA and Wordcloud system. As a result of the analysis, it was found that the self assessment and the reflection tool need to develop questions according to the grade group. In addition, we proposed to use these assessment tools in blended classes or various educational activities in the changing classroom environment. We hope that this paper provides implications for developing evaluation systems and tools for creative convergence education.

Objective: The aim of this study was to investigate the effect Tiger-step walking on the movement of the lower extremities during walking. Method: Twenty healthy male adults who had no experience of musculoskeletal injuries on lower extremities in the last six months (age: 26.85 ± 3.28 yrs, height: 174.6 ± 3.72 cm, weight: 73.65 ± 7.48 kg) participated in this study. In this study, 7-segments whole-body model (pelvis, both side of thigh, shank and foot) was used and 29 reflective markers and cluster were attached to the body to identify the segments during the gait. A 3-dimensional motion analysis with 8 infrared cameras and 7 channeled EMG was performed to find the effect of tigerstep on uphill walking. To verify the tigerstep effect, a one-way ANOVA with a repeated measure was used and the statistical significance level was set at α=.05. Results: Firstly, Both Tiger-steps showed a significant increase in stance time and stride length compared with normal walking (p<.05), while both Tiger-steps shown significantly reduced cadence compared to normal walking (p<.05). Secondly, both Tiger-steps revealed significantly increased in hip and ankle joint range of motion compared with normal walking at all planes (p<.05). On the other hand, both Tiger-steps showed significantly increased knee joint range of motion compared with normal walking at the frontal and transverse planes (p<.05). Lastly, Gluteus maximus, biceps femoris, medial gastrocnemius, tibialis anterior of both tiger-step revealed significantly increased muscle activation compared with normal walking in gait cycle and stance phase (p<.05). On the other hand, in swing phase, the muscle activity of the vastus medialis, biceps femoris, tibialis anterior of both tiger-step significantly increased compared with those of normal walking (p <.05). Conclusion: As a result of this study, Tiger step revealed increased in 3d range of motion of lower extremity joints as well as the muscle activities associated with range of motion. These findings were evaluated as an increase in stride length, which is essential for efficient walking. Therefore, the finding of this study prove the effectiveness of the tiger step when walking uphill, and it is thought that it will help develop a more efficient tiger step in the future, which has not been scientifically proven.

The purpose of this study is to examine the vertical and horizontal continuity between grades and publishers, respectively, by analyzing the readability of reading passages included in English textbooks for 5th and 6th grades of elementary school. In order to do so, a corpus was constructed with the reading passages contained in 10 textbooks, and the reading passages in each textbook were analyzed through Coh-Metrix. Also, it was examined whether there was a statistically significant difference between grades and publishers in readability through one-way ANOVA. The results are as follows. First, as a result of analyzing the difference in readability between publishers within the same grade, there was a statistically significant difference between fifth-grade textbooks in the L2 readability index. Second, as a result of analyzing the vertical continuity between grades within the publisher, the difficulty of textbook A was higher in grade 6 than grade 5 based on FRE and FKGL, which showed a statistically significant difference. On the other hand, when L2 readability was used as the standard, the difficulty of textbook B was lower in 6th grade than in 5th grade. This result seems to be because FRE and FKGL calculate readability based on sentence and word length, whereas L2 readability is based on content word overlap, word frequency, and syntactic similarity of sentences.

This study examined the participation of the people with stroke living in the community in terms of productivity, leisure, and social domain, and identified the effect on disability acceptance and anxiety. For data collection, from October 2018 to January 2019, data on disability acceptance, anxiety, and participation were collected from 192 people with stroke who used welfare centers and community services. For general characteristics, t-test and one-way ANOVA were used to compare participation according to descriptive statistics and general characteristics. Pearson correlation analysis was used for correlation between variables, and multiple regression analysis was used to identify causality. As the result, factors affecting the productivity of participation were labor(β=.28, p<.001), de-emphasis on disability salience(β=.14, p<.05), compensatory(β=.22, p<.01), and subjective anxiety(β=-.35, p<.05), and the explanatory power was 33%(F=9.44, p<.001). Leisure was expressed as self-satisfaction with disability(β=.18, p<.05) and the compensatory(β=.18, p<.05), and had an explanatory power of 23%(F=6.32, p<.001). Social activity was labor(β=.19, p<.01), and subjective anxiety(β=-.51, p<.05), which showed 23%(F=6.05, p<.001) of explanatory power. This suggests the importance of psychosocial factors for a changed life after the onset of a stroke, and a practical approach is needed to construct and apply programs to improve participation.

This study was a descriptive research to investigate clinical violence experience, response to violence experience, resilience and academic burnout and to identify the factors affecting the academic burnout among nursing students. The participants were 318 nursing students. who were recruited from the 2 Department of Nursing in B Metropolitan and 2 Department of Nursing in Gyeongsangnam-do. The structured questionnaire was self-administered from November 1 to 30, 2019. Data were analyzed through the SPSS/WIN 24.0 program using descriptive statistics, Independent t-test와 one-way ANOVA, Scheffe test, Pearson's correlation coefficient, and stepwise multiple regression. According to the results of this study, Mean score for academic burnout in nursing student was 2.58 out of 4 point. The factors of satisfaction with clinical practice(β=-.393, p<.001), satisfaction with nursing major(β=-.188, p<.001), responses to violence experience(β=.176, p<.001), perceived health status(β=-.156, p<.001) attacker(β=.135, p=.002), resilience(β=-.118, p=.016)were impact on the academic burnout level of nursing students. The total explanatory power accounted for 45.9%. In conclusion, since clinical practice satisfaction and major satisfaction are the factors that have the greatest influence on academic burnout, it is necessary to develop various educational strategies and a student counseling program to reduce negative reactions after experiencing violence and improve resilience. In addition, a qualitative study on the clinical violence experience, response to violence experience and academic burnout of nursing students is needed.
