Purpose: This study was conducted to develop a video education program for spinal surgery patients and to investigate the effect of the program on patients' uncertainty and educational satisfaction. Methods: This study employed a nonequivalent control group pretest-posttest design. The participants were 54 patients who had undergone spinal surgery in Busan from February to May 2017. The video education program was provided to the experimental group (n=28). The program consisted of providing existing leaflets to patients and repeatedly showing patients educational videos during their hospitalization. Leaflets were also provided to the control group (n=26) as part of traditional care. Patients' reported levels of uncertainty and educational satisfaction were measured. Data were analyzed using the chi-squared test, independent t-test, Mann-Whitney U test, and covariance analysis. Results: A significant difference was observed between the groups in uncertainty pre-post changes (U=239.50, p=.030). With the education variable controlled, there were significant differences between the groups in the educational satisfaction posttest (F=19.79, p<.001). Conclusion: The program was effective in reducing uncertainty and in enhancing educational satisfaction. Therefore, the video education program may be helpful for improving patient satisfaction and outcomes in various clinical fields.

This study was conducted from March 15 to March 19, 2019. The purpose of this study was to examine the recognition of uniforms and their images for the selection and development of uniforms and the pursuit of images for dental hygienists and students in some regions. Study methods included frequency analysis, factor analysis, reliability analysis, ANOVA, chi-squared test, and regression analysis. The collected data was analyzed using the IBM SPSS Statistics 21.0 program. This study found that students majoring in dental hygiene thought that uniforms influenced their image and that they influenced the image of the hospital. In addition, students who experienced clinical practice preferred the pants type to the uniform type and the color to achromatic color. In addition, these students preferred scrubs and the use of Crocs for shoes. The results of this study showed that dental hygiene students considered image transmission through uniforms as important. However, it appears that they prefer practical uniforms and shoes over uniforms that convey external images. This is a part that makes us aware of the need for changes in training clothes and training. In conclusion, it is necessary to develop a practical uniform while expressing the image of the institution, which will be reflected in future dental uniform selection.

This study investigates differences in demographic characteristics, shopping orientation, perceived risk, and satisfaction after purchase among consumer types. This study classifies consumer types according to their channel transition behaviors between the online and offline channels with a focus on the steps of information research and buying decision in buying decision-making process. The four consumer groups are as follows: off-off type (offline research-offline purchase), on-on type (online research-online purchase), on-off type (online research-offline purchase) and on/off-off type (online and offline research-offline purchase), off-on type (offline research-online purchase) and on/off-on type (online and offline research-online purchase). Data were collected from adults over 20 years old who had bought clothes within one year. The questionnaire was carried out from July, 2019 using a professional internet research panel; in addition, 500 sets of useful data were analyzed by descriptive statistics, factor analysis, reliability analysis, chi-squared test, ANOVA and Duncan-test using SPSS 21.0. The findings showed significant differences among the classified consumer groups for consumer demographics, shopping orientation, perceived risk, and purchase after satisfaction. The results imply that consumers show a variety of channel transition behaviors based on demographic variables, shopping orientation, and perceived risk. Understanding and adapting to consumer purchase behaviors will allow company distribution channels to be effectively managed and eventually increase consumer satisfaction as well as company sales volume.

When WC and group IV elements are added to Ti(C,N)-Ni cermet, microstructures of the cermet is changed. The change effects directly on the property of the material. In this study, the amount of WC and group IV elements of Ti(C,N) cermet tool was investigated. The composition of WC was changed from 5 to 20wt% to determine the effect of WC on the cutting performance of cermet tool. The more WC was added, the longer the tool life of the cermet tool was. The cermet with lwt% ZrC and l4wt% WC showed the best cutting performance among the investigated cermet tools. The cutting performance of cermet cutting tools suggests the possibility in interrupted cutting for reliability test experimentation was performed repeatedly with $Ti(C_{0.7},N_{0.3})- l4WC-1ZrC-20Ni$ cermet tool machining SCM440. The flank wear of cermet cutting tool at given time condition is suitable for Normal distribution and Log normal distribution by Chi squared test.

Yoo and Cook (2007) developed an optimal sufficient dimension reduction methodology for the conditional mean in multivariate regression and it is known that their method is asymptotically optimal and its test statistic has a chi-squared distribution asymptotically under the null hypothesis. To check the effect of dimension used in estimation on regression coefficients and the explanatory power of the conditional mean model in multivariate regression, we applied their method to several simulated data sets with various dimensions. A small simulation study showed that it is quite helpful to search for an appropriate dimension for a given data set if we use the asymptotic test for the dimension as well as results from the estimation with several dimensions simultaneously.

Background: In the maxillofacial region, giant cell granulomas occur in 2 clinical forms, central and peripheral. Despite histopathological similarity between these 2 forms totally different clinical behaviors have been reported. The present study was undertaken to compare mast cell and vascular concentrations in these pathologic lesions. Materials and Methods: In this cross-sectional descriptive study, 20 pathological samples of central giant cell granuloma (CGCG) and 20 samples of peripheral giant cell granuloma (PGCG) were selected and examined through toluidine blue staining for mast cell assessment and immunohistochemical staining by VEGEF antibody for comparing the number of mast cells. T-test, chi-squared test and backward multivariate linear regression were used for statistical analysis using SPSS 20. Statistical significance was set at P<0.05. Results: This study showed significantly greater VEGF expression and mast cell concentrations in CGCG compared to PGCG cases. Also there was a significant correlation between VEGF expression and the concentration of mast cells. No relation was found between age, sex and site of the lesion and concentration of mast cells or VEGF expression. Conclusions: It is feasible that higher concentrations of mast cells in CGCG versus PGCG samples might lead to more aggressive clinical behavior via vascular proliferation and angiogenesis. However, other biologic mechanisms should be considered in this situation.

Consumer citizenship is essential for better market and economy, and social capital plays an important role for raising consumer citizenship. This study explored the types of social capital developed on social media, and investigated the relationship between consumer citizenship of college students and social capital. Using data from 263 undergraduate students currently using social media, K-mean cluster analysis, one-way ANOVA, Duncan's multiple range test, chi-squared test, and multiple regression analysis were conducted. The major results were as follows. First, four types of social capital on social media were identified: mediocre social capital, instrumental-centered social capital, weak social capital, and strong social capital. Second, socio-demographic characteristics variables such as gender and work experience showed significant difference by type of social capital through social media. In addition, the most used social media and time for using social media variables showed significant difference by type of social capital through social media. Third, controlling for socio-demographic characteristics and social media usage pattern, the types of social capital had a significant effect on consumer citizenship. Based on the results, the implications for consumer education to develop consumer citizenship were suggested.
