Purpose: As the visual expression cue that can easily reveal and imprint the brand image to consumers becomes more important, franchise coffee shops are making various efforts to establish design elements and brand identity. Therefore, the purpose of this study is to examine the structural model between design elements, brand identity, brand association, brand personality, and brand image of franchise coffee shops from various angles, and to suggest a plan for using visual elements makes a brand image on the franchise in the future. Research design, data, and methodology: This study tests the structural relationship between design elements, brand identity, brand association, brand personality, and brand image of franchise coffee shops. design elements are divided into three attributes (interior design, product design). And brand identity is divided into two attributes (brand name, brand symbol/logo). In order to achieve the purposes of this research, research model and hypotheses were developed based on previous researches. All constructs were measured with multiple items developed and tested in the previous studies. The data were collected from 380 customers who visited franchise coffee shops and were analyzed through SPSS 26.0 and SmartPLS 3.0 statistical package program. Result: As a result of this study, first, it is confirmed that product design has a positive effect on brand association toward coffee shops. Second, interior design and product design have a positive effect on brand personality. Third, all brand identity have a significant positive impact on brand association and brand personality. Finally, brand association and brand personality of coffee specialty shops have a positive effect on brand image. Conclusions: The following implications of this study are as follows. This study is confirmed that there is an effect of design elements attributes and brand identity attributes on brand association and brand personality. And, the brand image was found to be influenced by brand association and brand personality. This suggests that it can be used to establish visible marketing strategies for franchise coffee shops. Therefore, it is necessary to further improve efforts to raise the level of the brand image through visual factors such as unusual interior design, product packages.

Purpose: The purpose of this study was to examine whether there is difference in the effects of aromatherapy on dysmenorrhea by research design. Methods: Findings from the two different research designs (Nonequivalent control group pretest-posttest [NCG] design vs. two-group crossover design) were compared in regard to the effect of aromatherapy on dysmenorrhea. The subjects of the NCG design and the crossover design were a total of 58 female nursing students. The treatments (aroma essential oil inhalation and carrier oil inhalation) were given using a necklace. The data were analyzed by Fisher's exact test, t-test, Mann-Whitney test, paired t-test, and Shapiro-Wilk test using the SPSS/WIN 12.0 program. The effect size for the two research designs was calculated. Results: In both research designs, the level of dysmenorrhea and menstrual pain after the aroma treatment were not significantly different from those after the placebo treatment. The effect size of the NCG design was higher than that of the crossover design. Conclusion: Aroma inhalation may not be effective in managing dysmenorrhea and menstrual pain. In order to further clarify the efficiency of research design and the effect of aromatherapy on discomfort during menstruation, replication studies are necessary. Future studies need to examine the effects of different research design on non-interval variables.
