  • In this paper, We conducted to find out what factors may affect the development of franchise businesses by reviewing the success factors of the domestic franchise business. The research was conducted by the CEOs of Gwangju and Jeonnam Franchise Business and a total of 137 items were used in the empirical analysis. Factors influencing success of the franchise business were designed in five areas : ability of the franchise CEO, franchise system, brand management, capacity of the parent store, and product differentiation. We conducted multiple regression analysis and simple regression analysis for the research assumptions, Validation of the relationship between variables revealed that the ability of the franchise CEOs, franchise systems, brand management, and product differentiation did not significantly affect the increase in member sales, so the ability of the shareholders to increase their sales was important. However, the impact on revenue growth at franchise headquarters has all been significant, The increase in sales of franchises has a significant influence on the increase in profits of franchise headquarters, the report said. It was also found that an increase in the sales of franchises has a significant influence on the success of franchises. Finally, it was revealed that increasing profits at franchise headquarters significantly affects the success of the franchise business.

  • Purpose - The purpose of this study is to examine the extent to which internal brand communication (IBC) impacts on brand commitment (BC). Research design, data, and methodology - A structured questionnaire has been built and distributed on a total sample of 650 banking staff working in five public banks in Pakistan. Results - The findings of PLS-SEM revealed that besides the indirect effect of internal brand communication (IBC) on brand commitment via brand knowledge, the study also exposes a direct positive effect of IBC on brand commitment. This study also reveals that brand commitment is affected by brand knowledge and internal brand communication practices. The result of mediation reveals that brand knowledge partially mediated the relationship between independent and dependent variables. Practical implications- This study empirically validates that internal brand communication and brand knowledge are prerequisites for brand commitment. Therefore, managers, particularly in-service enterprises, should provide sufficient IBC practices and appropriate brand knowledge to enhance employees' brand commitment. Conclusions - The comprehensive analysis of the impact of brand knowledge on the proposed relationship. It further adds up to the branding literature, which is mostly qualitative and lacks empirical validation.

  • Over the past centuries, industrialization in developed and developing countries has had a negative impact on global warming, releasing $CO_2$ emissions into the Earth's atmosphere. In recent years, the transportation sector, which emits one-third of total $CO_2$ emissions in the United States, has adapted by implementing a climate change action plan to reduce $CO_2$ emissions. Having an environmental policy might be an essential factor in mitigating the man-made global warming threats to protect public health and the coexistent needs of current and future generations; however, to my best knowledge, no research has been conducted in such a context with appropriate statistical validation process to evaluate the effects of climate change policy on $CO_2$ emission reduction in recent years in the U.S. transportation. The empirical findings using an entity fixed-effects model with valid statistical tests show the positive effects of climate change policy on $CO_2$ emission reduction in a state. With all the 49 states joining the climate change action plans, the U.S. transportation sector is expected to reduce its $CO_2$ emissions by 20.2 MMT per year, and for the next 10 years, the cumulated $CO_2$ emission reduction is projected to reach 202.3 MMT, which is almost equivalent to the $CO_2$ emissions from the transportation sector produced in 2012 by California, the largest $CO_2$ emission state in the nation.

  • Importance-Performance Analysis(IPA) holds the assumption that the degree of physical fulfilment of quality attributes and the satisfaction of that attribute is linear. Therefore, IPA can be applied to the traditional one-dimensional attributes, not to other quality elements such as attractive or must-be attributes. To overcome this problem, several articles introduced methods that integrate IPA into the concept of two-dimensional quality. However, these articles are rather conceptual focusing on the differentiation of quality attributes depend on quality elements in IPA. To provide empirical evidence of the dependent relationship between attribute importance and satisfaction in IPA, this study introduces a weighted importance approach and provides validation method using Bacon's priority model, a regression model. For this, the current research investigates 23 quality attributes of TV set for the results of Kano's model, which are adopted from Kim et al., and conducted a survey of 118 university students for the results of the importance/satisfaction and improvement priority. The result of the proposed approach shows better result than those using the conventional way, based on R-square of the regression model.

  • Purpose Based on consumers' economic, psychological, self-development and conversion costs, this study discusses the relationship between consumers' negative attitude to their shadow work during the course of using self-service in unmanned supermarkets and their behavior. Design/methodology/approach Along with the Hirschman(1970)'s EVLN(Exit, Voice, Loyalty, and Neglect) reviewed, the proposed model of this study is based on the S-O-R model(Mehrabian and Russel, 1974) and mental accounting theory(Thaler, 1999), having empirical validation. Findings In the process of visits and consumption in unmanned supermarkets, increasing economic and psychological benefits can effectively reduce consumers' negative attitudes towards shadow work. In addition, the increase in switching costs will also effectively reduce consumers' negative attitudes towards shadow work. When shadow work holds a negative attitude, all the three kinds of actions will occur. Unmanned supermarket operators use consumers to create value while giving a certain return to them, which is conducive to the sustainable development of unmanned supermarket enterprises.

  • The design response spectrum presented in the seismic design standard reflects the characteristics of the tectonic environment at a site. However, since the design response spectrum does not represent the ground motion with a specific earthquake magnitude or distance, input ground motions for response history analysis need to be selected reasonably. It is appropriate to use observed ground motions recorded in Korea for the seismic design. However, recently recorded ground motions in the Gyeongju (2016) or Pohang (2017) earthquakes are not compatible with the design response spectrum. Therefore, it is necessary to convert the recorded ground motion in Korea to a model similar to the design response spectrum. In this study, several approaches to adjust the spectral acceleration level at each period range were tested. These are the intrinsic and scattering attenuation considering the earthquake environment, magnitude, distance change by the green function method, and a rupture propagation direction's directivity effect. Using these variables, the amplification ratio for the representative natural period was regressed. Finally, the optimum condition compatible with the design response spectrum was suggested, and the validation was performed by converting the recorded ground motion.

  • With the wide spread of the Common European Framework of Reference (CEFR) scales, many studies attempt to apply them in routine teaching and rater training, while more evidence regarding criterial features at different CEFR levels are still urgently needed. The current study aims to explore complexity features that distinguish and predict CEFR proficiency levels in oral performance. Using a quantitative/corpus-based approach, this research analyzed lexical and syntactic complexity features over 80 transcriptions (includes A1, A2, B1 CEFR levels, and native speakers), based on an interview test, Standard Speaking Test (SST). ANOVA and correlation analysis were conducted to exclude insignificant complexity indices before the discriminant analysis. In the result, distinctive differences in complexity between CEFR speaking levels were observed, and with a combination of six major complexity features as predictors, 78.8% of the oral transcriptions were classified into the appropriate CEFR proficiency levels. It further confirms the possibility of predicting CEFR level of L2 learners based on their objective linguistic features. This study can be helpful as an empirical reference in language pedagogy, especially for L2 learners' self-assessment and teachers' prediction of students' proficiency levels. Also, it offers implications for the validation of the rating criteria, and improvement of rating system.

  • Most leadership styles are generally designed to enhance the cognitive and behavioral skills of leaders with the implicit assumption that this would ultimately translate into high performance. As we are moving towards Industry 4.0, organizations must employ leadership styles that will help the organization succeed. Thus, the objective of this paper is to confirm the determinant factors for Fourth Industrial Revolution (4IR) leadership attributes in Malaysian manufacturing companies. Stratified sampling was used to select the sample. Data was collected using the online survey method, where the response rate was 43 percent. The respondents consisted of respondents aged from 31-40 years old, with 69 respondents. In terms of race, the highest number of respondents are the Malays. Questionnaires were distributed to middle and top-level managers from manufacturing companies which were listed in the Federation of Malaysian Manufacturers (FMM). Confirmatory Factor Analysis (CFA) was used to confirm the reliability and validity of the construct. Based on the analysis, 66 items could be used to measure the 4IR leadership attributes. The validation of 4IR leadership can also provide predictive implications on improving leaders' performance, given the different attributes confirmed by the findings.
