NFTs are touted as revolutionary to market and monetize digital assets. However, critics have questioned NFT value, labeling it as fraudulent. Despite mixed reviews, various firms are leveraging NFTs as a value proposition for customers. In this study, using service-dominant (S-D) logic, we explore how NFTs can help firms in value co-creation and service exchange. We propose and test a conceptual framework using a multi-method approach -1) we investigate NFTs popularity using historical news articles spanning ten years, 2) we use a case study to examine business NFT use in value co-creation and service exchange, subsequently, proposing a conceptual framework illustrating such value exchange, 3) we test our conceptual framework by analyzing data from multiple sources, including surveys, online forums, social media, and transactions. Results from our study, provide business valuable insight into using NFTs as value co-creation and service exchange tool.

The Korean Legation in Washington, D.C., is a proof that Emperor Kojong of Chosun Dynasty tried to establish relationship with the U.S. in 1891, that was before the declaration to establish Korean Empire. In that sense, the building is a historic place. The legation building is a symbolic place attesting to the turbulent history at the time of 1890 to 1910, when Korea had to suffer the forced treaty with Japan in 1905 and the annexation into Japan, and then to the 20th century up to the present time, 2014. The legation building can be turned into a space to host well-planned exhibits to show Korea's history and culture to local residents, foreign visitors to Washington, D.C., and overseas Koreans. The followings are the basic principles for the future use of the legation in line with the basic direction. The building's use should not be limited to museum, but should be flexible to accommodate various different practical usage. It is necessary to make the Korean Legation building that can incorporate the characters and the history through modern interpretation of the historicity of the place, the Korean culture, and historical events. The future usage of the Korean Legation building should enhance the value as a cultural heritage by linking the interpretation of the historical events and real life shown through exhibits, performance and people.

When performing steering by an autopilot (automatic steering gear), a sensitivity adjustment is mainly determined by P value and D value. These values differ in the optimal combination by model of ship and external forces. This research was carried out simulation case studies and examined movement of Pure Car Carrier, which easily received ship by wind pressure influence in low speed We investigated the relation of horizontal migration(transfer) of ship's body and P-D value. Based on it, four parameters of P-D at approaching berth could be suggested Hence there were suggestions of parameters; Distance to maximum lee point, Time to maximum lee point, Time to return to original course and Time to 300th second. The correlation of these parameters and P-D value were also considered. As a result, we think that this index, like formulated P-D, leads to an easy and safe navigation by utilizing these indices.
