Global consumers are increasingly enjoying popular cultural products such as music, film, television and other audiovisual media content through online social media community networks. Recently, Korean pop music, or K-pop, has become one of the most dynamically distributed forms of pop culture in the global pop market through these 'social distribution' networks. This article explores the ways that this new mode of social distribution is characterised by bottomup grassroots aspects as well as corporate-controlled top-down aspects by analysing the recent dynamics and practices of K-pop consumption and circulation on social media, using a case study of K-pop fandom in Indonesia and the 'Gangnam Style' phenomenon.

This study examined 1-year persistency with cholinesterase inhibitors (ChEIs) for the treatment of elderly Alzheimer's dementia (AD) patients in Korea. Korean Health Insurance Review & Assessment Service database from January 2005 to June 2006 was used. Patients aged 65 or older with AD diagnosis who were first prescribed a ChEI were included. The 1-year persistence, persistency rate, and switching patterns during the follow-up period were identified. Mean time to drug discontinuation was analyzed, and persistency rates between different patient factors were compared. The 1-year persistency rate of newly treated 6,461 AD patients was 24.0%, while 50% of study patients discontinued treatment by 91 days from initiation. Persistency rates of female patients (22.8%), patients in rural areas (12.7%), and primary care (10.2%) were relatively low (p < 0.001). Persistency rate differed between age groups (p < 0.001). Overall proportion of switching was 6.6%. The 1-year persistency rate of ChEIs for AD patients in Korea did not reach those of previous researches in other countries. Patients less likely to remain on therapy should be especially monitored to optimize treatment persistence.

Transparent antennas have been continuously developed for integration with solar cells, vehicular communications, and ultra-high-speed communications such as 5G in recent years. A transparent antenna takes advantage of spatial extensibility more so than all other antennas in terms of wide range of usable area. In addition, the production price of transparent antennas is steadily decreasing due to the development of nano-process technology. This paper reviews published studies of transparent antennas classified by various materials in terms of optical transmittance and electrical, sheet resistance. The transparent electrodes for the transparent antenna are logically classified and the transparent antennas are described according to the characteristics of each electrode. Finally, the contributions transparent antennas can make toward next-generation 5G high-speed communication are discussed.
