Purpose - Brand equity has emerged as an indispensable marketing tool for firms engaging their business in developing nations. This study proposes that the country of origin image and advertising will affect the Korean brand equity formation, which leads to repurchase intention of Korean brands. In the study, attitude factors are applied in brand equity theory to predict repurchase intention of Korean brands. Cognitive brand equity, such as brand awareness, brand association, brand image and attitudinal brand equity, such as perceived quality and brand loyalty are considered with regards to their attitude towards the Korean brand. Design/methodology - A total of 178 Myanmar consumers out of 200 participants who have used Korean brands answered the survey and data were analyzed through SmartPLS 3.3.2 version. PLS-SEM is considered a more suitable analysis to pin down and evaluate the cause-effect relationship among all of the constructs with relatively complex models. Findings - Our results substantiate that the country of origin image positively affects brand awareness, brand associations, and brand image and advertising awareness positively affects brand awareness. Brand awareness gives positive effect only on brand association, which sustains a positive effect on brand image and brand loyalty. Brand image only has a positive effect on perceived quality, which again affects repurchase intention and brand loyalty. Brand loyalty also shows a positive effect on repurchase intention. Originality/value - Brand equity dimensions were viewed as cognitive and attitudinal outcomes of brand equity which affects repurchase intention. The drivers of brand equity were considered from the perspective of country of origin image that firms cannot control or mange, and advertising awareness which firms can control and manage. The findings also explored the relationships between cognitive and attitudinal brand equity.

Data redundancy is problematic in that it not only induces heavy storage management cost but also could bring critical degradation of information systems. Unfortunately, to our knowledge, only few enterprises willingly afford time and efforts for the faithful conceptual design to prevent the degree of inappropriate data as much as they could, while most of enterprises pay rare attention to the notion of that sort of data quality. Wondering if there would be any other way to design the enterprise.wide data design without prior knowledge about business works is our major motivation for this study. In this paper, we present our data modeling methodology in which associations among objects in each sentences of a business job descriptions are treated as the focal point in database design. A proposed agent for automated design tool simply takes a business job description written in natural language as an input, and then designs an entity relationship diagram with some smart rules. We introduce the scope of the proposed agent and its detailed logics with several examples. And then, we verify the appropriateness of the resulted associations among objects. Lastly, we perform case studies to evaluate the devised agent's applicability to a business field.
