Brands have begun to act without giving in to the challenges facing our society. Just like the slogan in the novel "The Three Musketeers" by Alexandre Dumas proclaimed, "All for one, one for all!" in the age of transmedia the success of brand activism must reflect the same principle. Specifically, by embracing the big as well as the little stories of consumers scattered everywhere, each and every one should create a huge resonance. This means that brands should use the cultural lever of transmedia so that the various stories of consumers do not fade into oblivion and, furthermore, expand the brand's call to action. By analyzing brand activism cases in business, this study explores the effectiveness of brand activism for advertisers to develop a better understanding of brand communication strategy. Building on findings that show new young generation consumers to favor brands that respond to social, political, and environmental issues and conceptual implications of the snowball effect, this study emphasizes consumer participation in the brand story creation process and the need for brands to aim for high standards of professionalism and accountability, so that they can grow together with their consumers.

Purpose - The objective of this research is to investigate how selected Korean General Trading Companies, (KGTCs), manage their international distribution channels to sustain the growth of the international marketplace. Specifically, the following questions were answered: What is the profile of the respondents in the position from the company, the experience in channel of distribution operations, the number of distribution channels existing in the international marketplace. Research design, data, methodology -The thirty-nine respondents representing 55 percent have less than 10 years of experience in channel of distribution operations while 34 respondents, equivalent to 45 percent have 10 or more years of experience. All of the respondent KGTCs are using the channel of distribution in their export operations in Asia. Respondent KGTCs' 2015 export sales in Asia were between US$ 100 to 200 million. Results - There are no significant differences in the perceptions of the two groups of respondents with regard to the perceived practices of KGTC in the management of international distribution channels. Exporting companies use common sense when managing conflicts and emphasize the importance of a clear contract which states what obligations and requirements there are of each party in order to prevent conflict. Conclusions - The higher level of details in the contract, the lesser would conflicts arise. The more intense communication, the higher level of information exchange. The higher level of details in the contract, the lesser would conflicts arise.

How does a public health crisis play into the digital rhetoric of states? As Covid-19 is presenting a situation in which countries need to manage the international environment in a relatively short period, their practices could signal how digitization is going to influence public diplomacy in the longer run. This paper explores state public diplomacy in the context of a public health crisis. It develops a theoretical framework of public diplomacy on social media through how and what states communicated during the first year of the Covid-19 pandemic. Through keyword and hashtag analyses, we identify two patterns. First, states usually regard social media as an instrument for domestic communication rather than public diplomacy. The international impact of messaging has not been prioritized or well-recognized. Social media platforms such as Twitter have global outreach and messaging can be seen by audiences all over the world. Messages intended for the domestic audience could have an international impact. Thus, any communication on digital platforms should consider their public diplomacy outcomes. Second, while social media platforms are claimed to be for networking at different levels, states tend to connect with other states rather than with international organizations during the pandemic. States do not like to mention international organizations like the WHO and the UN on Twitter. Instead, they were either busy dealing with internal problems or cooperating with another state to combat the virus.
