'Reboot' and 'Homage' are using as creative techniques in traditional storytelling media fields such as movies or dramas, but the possibility of expanding the transmedia story world has not yet been presented. This study was written to present a new concept of transmedia story world expansion type using the 'Reboot' and 'Homage' methods. 'Reboot' and 'Homage' are typical storytelling methods of K-POP idol groups that need to develop content. I selected , , and , which have built their story world, and examined both the narrative creation section and the marketing application section. The result of the study is as follows. First, EXO is an example of a reboot case. They set the original set as 'past' and insert the new storylines. Second, BTS is an example of a character's reboot. They built a story world by paralleling 'Idol BTS' and 'Character BTS'. Third, Wanna One is an example of the original story world's homage. They reorganize the story world of and attracting the attention of the existing audience. Fourth, BTS is an example of other media homage which reinterprets the meaning of BTS characters and story world by using the meaning of classic works.

Polyurethane oligomers (PUOs) such as UA8297, UP127 and EB8200 were utilized to enhance the anti-bullet property of Dyneema$^{(R)}$/vinylester composites. First, prepregs of PUO and vinylester (XSR10) were prepared via spray coating on Dyneema$^{(R)}$ fabric at 21 % resin content (by volume). In addition, spray coating and film lamination were also carried out with a mixture of XSR10/PUO for selected PUOs. Next, the prepregs were dried at RT for 1-2 h and then at $100^{\circ}C$ for 30 min to remove the solvent and to provide partial cure when necessary. The prepregs were stacked in 24 layers and cured at $120^{\circ}C$ for 5 min under the contact pressure and for additional 25 min at 150 $kg/cm^2$. Finally, the anti-bullet properties of composite samples were evaluated by measuring $V_{50}$ with simulated fragment projectile (SFP, 17 gr). The results showed a 6.5 and 9.0 % increase of $V_{50}$ with UP127 and EB8200, respectively.

This study explored the mechanism by which stars and fans build a global fandom community based on social connectivity of social media based on BTS' official Twitter and in-depth interviews with Chinese, American, and Korean fans. Stars and fans use the connectivity of social media to build a pseudo-private relationship that crosses public and private affairs. Even though they won the award, BTS "congratulates" the fan club, ARMY, and organizes a dialogue method so that each fan becomes the subject. From a fan's point of view, it comes to be seen as a personal message to them, which is not just applied to the text composition method. On days when there is no public message such as official activities or anniversaries, a device to communicate without missing a day has been prepared by raising private messages or previous memories. It was found that the sense of constant connection strengthens fans' sense of community toward each other.

This paper tries to critically examine how development of digital technology affects on the processes of production, consumption and intermediation of popular culture. We focus on the case of BTS to find changes after new media environment. In production part, artist produces diverse contents through multiple platforms to be a 'total package', and in consumption part, fans vote and promote online to support their artist, and their roles have expanded to the cultural intermediary at some part, so on the part of intermediation, inequalities from the power relations have changed in a part.

Korean-peacekeeper's transparent armors in Iraq showed delamination, cracking and clouding a decade ago. And there were also similar deterioration recurrences in KLTV during the operational test a few years ago. Also, the differences between operational capability & lab Bullet-proof test condition, and insufficiency of military protection spec resulted in incomplete bullet-proof results. Moreover, although so many ground weapon systems have been developed, there were not secure test & evaluation codes to verify transparent armoured glasses equal to advanced-overseas products. So in this study, first, environmental test codes were established that all tests should be carried out as the application of only one specimen with newly adopted thermal shock test instead of completing each test with different one. Second, protection standards were integrated through the analysis of global developed country's specifications and reinforced as adding to the real mock-up condition if vehicle's glasses are smaller than standard specimen. Hereby, by applying to test-codes which including actual operational & vehicular conditions, the gap between development test and operational environment was minimized.

Ballistic property of Heracron/phenol composites was evaluated as a function of polyurethane (PU) type and their loadings. First, prepregs of phenol and polyurethane were prepared by spray coating on Heracron fabric and then they were utilized to prepare composite by varying their ratio. Next, they were consolidated at $150^{\circ}C$ for 25 min at $150kg/cm^2$ pressure and then ballistic property was measured with 1.1 g FSP (22 cal). V50 was evaluated interms of polyurethane type and ratio of phenol/PU prepreg.
