Solid rocket motor that includes AL powder in propellant gets slag during static firing test. Slag is piled up to weak area in motor case and causes dangerous phenomena like explosion of motor. In this paper, It is shown that boots gap liner casting process was developed and static firing test was performed with better results.

Historically, white clothes have been passed down through the generations as the symbol of the Korean people. This study was motivated after coming across a text written by Lee Ok(李鈺, 1760~1815), a writer during the Joseon dynasty. Lee wrote that "Koreans mostly wear blue clothes." This raised questions regarding the wearing practice of the white clothes at the time of King Jeongjo's reign(1776~1800), and led to further studies on the matter. The results show that discussions were held about changing the color of the government official's changui(氅衣) from white to blue. An order was also given replacing white boots with black boots. Therefore, it is supposed that blue clothes phenomenon was influenced from the blue changui policy. However, this change was temporary as later generations wore preferred white with the exception being women's skirts. Women preferred blue skirts to white skirts for a long period. Detailed analysis of the white changui showed that people were burdened by high dyeing costs, and this was a big factor as studies indicated a large gap in wealth disparity. In a society that put funeral and ancestral rites as one of its priorities, the white clothes could have been favored due to its multi-functional use. Also, the noblemen who set importance on Gija(箕子) Joseon connected white clothes custom to Gija. This connotes that the reason for wearing white clothes differed depending on the class. And as white clothes were widely worn, people developed different ways of wearing the clothes for aesthetic purposes.

The body is an important object of costume expression, and the reflection of the aesthetics of the body according to age, culture, individual or group determines the form of the costume. In particular, British artist Leigh Bowery provided many designers and celebrities with original design ideas. Leigh Bowery's costumes are related to the carnival concept. Thus, this study analyzed Leigh Bowery's life and works, and examined Michael Bakhtin's grotesque carnivalesque theory. Based on Bakhtin's carnival theory around 100 works by Leigh Bowery, in the form of YouTube videos and DVD clips were analyzed in this study. The results of the analysis Leigh Bowery's body and costume research are as follows. First, this study can define fetishism as a characteristic of costumes such as body suits, harnesses, high-heeled boots, and stockings, that stress the body. Second, the character of the body is not expressed as that of an idealized body, but the fat and ugly aspect are revealed. Third, Leigh Bowery's costumes are characterized by ambiguity. The costumes blur the boundaries between women and men. Fourth, common sense, combined with normal and bizarre, brings out a strong sense of carnival humor with ridiculousness arising from the gap between reality and reality. His performance has had a significant impact on victims of discrimination or unequal treatment in sexual, racial, and age-related situations. This study should inspire many designers through the study of Leigh Bowery's body expression and dress, but it also introduces fashion icons that are not well known in Korea.
