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.

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.

Purpose: The purpose of the present study was to assess the effectiveness of a nursing skills enhancement program in improving the self-efficacy and self-esteem of senior nursing students. Methods: This was a nonequivalent control group pretest-posttest design study that enrolled 306 senior nursing students. The nursing students were randomly assigned to an experimental(n=132) or control group (n=174), and students assigned to the experimental group completed a nursing skills enhancement program, which consisted of four skills training components: IV infusion, enema, $O_2$ therapy by means of cannulation and urinary catheterization. Data were analyzed with frequency, the chi-squared test, and the paired t-test using the SPSS/pc 15.0 statistical program. Results: Our results showed that the self-esteem and self-efficacy of nursing students who were assigned to the nursing skills enhancement program were significantly better compared to those of nursing students in the control group (t=10.198 and t=6.452, for self-efficacy and self-esteem, respectively, p<.001 for both variables). Conclusion: Our findings clearly show that a nursing skills enhancement program is effective in improving the self-efficacy and self-esteem of senior nursing students.
