  • With diffusion of various mobile devices, mobile learning has been one of the dominant learning styles in education fields. The purpose of this research is to examine the difference between students' perceived importance-performance of mobile learning satisfaction. The researchers reviewed the literature looking for variables which affect influential factors of students' mobile learning satisfaction such as system, contents, service, use, and outcome. As a result of t-test, the performance is lower than the importance of all the influential factors. Also, according to the result of Importance-Performance Analysis(IPA) matrix, it was noted that system factor is the most crucial factor in improving mobile learners' satisfaction. This result implies that offering technical support and simplifying the navigation design for mobile learning are urgently required.

  • Objectives: This study was conducted to identify the effects of the Daoyin and corrective exercise program on musculoskeletal pain among acute sprain patients due to traffic accidents. Methods: This study was carried out on the 35 patients who had been treated on musculoskeletal pain due to traffic accidents and was performed from March 1 to June 31, 2011 in the department of oriental rehabilitation medicine, Dun-San oriental hospital attached Dae-Jeon university. And we divided those 35 patients into 2 groups; sample group took treated with the Daoyin and corrective exercise program control group took common treatment only. All of the subjects were examined en visual analogue scale(VAS), state-trait anxiety inventory(STAI) score and presence of treatment after hospital discharge. The data was collected before and after the treatment, after hospital discharge. SPSS ver. 12.0 for Windows was used fer data analysis, and the analysis, and the general characteristics were demonstrated by frequency number and two-independent sample t-test. The effects of the Daoyin and corrective exercise program were analyzed by matched pair t-test and analysis of covariance. Results: On the VAS score, there was significant difference between before and after treatment, and before and after hospital discharge. And on the VAS scores, sample group mowed higher significant change of VAS than control group. And on the STAI score, there was significant difference between before and after treatment. But it did not show statistical significance between sample and control group. Conclusions: The Daoyin and corrective exercise program is an effective treatment fer musculoskeletal pain among acute sprain patients due to traffic accidents.

  • In this study we investigate how motive and personal relations of volunteers impact their volunteering satisfaction. The objects were 313 members of a volunteer group in ${\bigcirc}$-gun, central region. We conducted survey from 2014 April 2 to August 31. The data were analyzed by correlation analysis, t-test, multiple regression analysis, through SPSSWIN 18.0 program,(empirical analysis verification : significance level of 5%). The results are as follows: First, with the general characteristics, we found that females, the educated, and the married get more satisfaction. Second, with the local characteristics, long-term residents and the members, who think volunteer activity contribute to the local development, feel more satisfaction. Third, volunteer who has high participation motives, has strong volunteering satisfaction. Finally, volunteers feel more satisfaction when they maintain a good relationships in interpersonal relationship. This study implicates that volunteer activity participation motives and personal relations have a great impact on volunteering satisfaction, to be the basis for volunteer's satisfaction improving policy in the future.

  • In this study, the intrinsic static/dynamic fracture toughness of Al 7175=T74 is evaluated from the apparent static/ dynamic toughness of notched specimen, The critical average stress fracture model is suggested to establish the relationship to predict the intrinsic fracture toughness from the apparent fracture toughness of a notched specimen. The critical average stress fracture model is established using the relation between the notch root radius and the effective distance calculated by finite element analysis. Also, effective distance is applied to estimate the failure criterion for the combustion pipe with notch. It is conclude that the true fracture toughness can be estimated from test results of apparent fracture toughness measured by using a notched specimen.

  • The purpose of this study was to investigate the relationship between serum vitamin E levels and the risk of allergic rhinitis among Koreans. This study is a secondary data analysis using big data from the seventh Korea National Health and Nutrition Examination Survey (KNHANES VII-3), which was conducted in 2018. Complex-sample descriptive statistics, t-test, ANOVA and odds ratio were used for data analysis in SPSS 25. The average serum vitamin E level among Koreans aged above 10 was 12.60 mg/L, and 15.9% had been diagnosed with of allergic rhinitis by a doctor. Lower serum vitamin E levels were significantly associated with the prevalence of allergic rhinitis (β=-0.05, p=.013). Therefore, efforts to prevent and manage allergic rhinitis among Koreans should incorporate regular monitoring of vitamin E level and ongoing research into antioxidants.

  • Value is one of the most useful variable for achieving marketing concept that satisfy consumer needs. The issue related to which value consumers have when they're shopping and which effect this shopping value has on the process of consumer satisfaction formation, would be helpful to understand the post-purchase behavior as well as the process of pre-purchase decision making. Therefore, the objective of this study was to clarify differences in the process of satisfaction formation in relation to the type of shopping value. The study was conducted in three steps. Through the two steps, measurement instruments were developed. At the last step, judgement sampling method were utilized to collect the data and subjects were 614 university students. Factor analysis, cluster analysis, frequencies, t-test, and structural equation model analysis were used to analyze the data. Two groups regarding shopping value were found, which included consumers with hedonic shopping value and consumers with utilitarian shopping value. Overall, the results revealed a similar tendency in the process of satisfaction formation between two groups. But the tendency, which expressive product performance was related to the positive consumption emotion more than instrumental product performance was and instrumental product performance was related to the negative consumption emotion more than expressive product performance was, was clearer in consumers with utilitarian shopping value than in those with hedonic shopping value. In consumers with utilitarian shopping value, expressive product performance has a greater effect on satisfaction than instrumental product performance did, but in consumers with utilitarian shopping value, expressive product performance showed a similar effect on satisfaction with instrumental product performance. Understanding of the post-purchase behavior of the consumers with hedonic shopping value and the consumers with utilitarian shopping value and practical administration of the differences of the two groups would contribute to build useful marketing strategies.
