Therefore, from the design stage, the required performance of the propeller is estimated, and a model propeller test is performed in a common tunnel. In the previous study, the location of cavitation was estimated by embedding the sensor in the upper hull of the propeller and applying the matching field processing technique used for estimating the source localization in the underwater acoustic field or inverting environmental factors. In order to apply the cavitation localization technique using the acoustic sensor to real ships, it is necessary to minimize the number of sensors to be installed on the hull in consideration of the process and cost. Therefore, in this study, the localization performance is improved by applying the forward neural network learning technique used in various fields to the cavitation localization technique using three acoustic sensors, which showed low accuracy in previous studies.์ œ 1 ์žฅ ์„œ ๋ก  1 ์ œ 1 ์ ˆ ์—ฐ๊ตฌ ๋ฐฐ๊ฒฝ ๋ฐ ๋ชฉ์  1 ์ œ 2 ์ ˆ ๋…ผ๋ฌธ ๊ตฌ์„ฑ 3 ์ œ 2 ์žฅ ๊ธฐ์กด์—ฐ๊ตฌ ๋ถ„์„ 4 ์ œ 1 ์ ˆ ํ”„๋กœํŽ ๋Ÿฌ ์บ๋น„ํ…Œ์ด์…˜ 4 1. ๋ฐœ์ƒ ์›๋ฆฌ ๋ฐ ์ข…๋ฅ˜ 4 2. ์บ๋น„ํ…Œ์ด์…˜ ์Œํ–ฅํŠน์„ฑ 6 ์ œ 2 ์ ˆ ํ”„๋กœํŽ ๋Ÿฌ ์บ๋น„ํ…Œ์ด์…˜ ์œ„์น˜ ์ถ”์ • 9 1. ์œ„์น˜ ์ถ”์ • ๊ธฐ๋ฒ• 9 2. ๊ด‘๋Œ€์—ญ ์ •ํ•ฉ์žฅ ์—ญ์‚ฐ ๊ธฐ๋ฒ• 11 2.1. ์œ„์น˜์ถ”์ • ์ ˆ์ฐจ 11 2.2. ์œ„์น˜์ถ”์ • ๊ฒฐ๊ณผ ๋ฐ ํ•œ๊ณ„ 14 ์ œ 3 ์ ˆ ์ˆœ๋ฐฉํ–ฅ ์‹ ๊ฒฝ๋ง(FNN) 16 ์ œ 3 ์žฅ ์‹คํ—˜ ๋ฐ ์˜ˆ์ธก๋ชจ๋ธ ์ƒ์„ฑ 19 ์ œ 1 ์ ˆ ์‹คํ—˜ํ™˜๊ฒฝ ๋ฐ ์กฐ๊ฑด 19 ์ œ 2 ์ ˆ ์ˆœ๋ฐฉํ–ฅ ์‹ ๊ฒฝ๋ง ์˜ˆ์ธก ๋ชจ๋ธ ์ƒ์„ฑ 22 1. ์ฃผํŒŒ์ˆ˜ ๋Œ€์—ญ ์„ ์ • 22 2. ์‹ ํ˜ธ๋‹จํŽธ ๋ฐ์ดํ„ฐ ์ƒ์„ฑ 23 3. ๋ฐ์ดํ„ฐ ์ „์ฒ˜๋ฆฌ 24 4. ์˜ˆ์ธก๋ชจ๋ธ ์ƒ์„ฑ 25 ์ œ 4 ์žฅ ๊ฒฐ๊ณผ ๋ฐ ๋ถ„์„ 31 ์ œ 1 ์ ˆ ์œ„์น˜์ถ”์ • ์ •ํ™•๋„ ๋น„๊ต ๊ฒฐ๊ณผ 31 1. 3_MFP ~ 3_FNN๊ฐ„ ์ •ํ™•๋„ ๋น„๊ต 31 2. 3_MFP, 4_MFP, 5_MFP ~ 3_FNN๊ฐ„ ์ •ํ™•๋„ ๋น„๊ต 33 3. ์‹คํ—˜ ์กฐ๊ฑด๋ณ„ ์ •ํ™•๋„ ๋น„๊ต 34 ์ œ 2 ์ ˆ ๊ฒฐ๊ณผ ๋ถ„์„ 36 ์ œ 5 ์žฅ ๊ฒฐ ๋ก  37 ์ฐธ๊ณ ๋ฌธํ—Œ 39 Abstract 41์„

Growing through experiencing a process of becoming a boxer, the researcher becomes a boxer as well as a member of the gym. As the final outcome, it proposes three different layers of subjects, and synthesizes them: 1) A boxing gym as material. 2) A dream of being world champion as spirit carved into material. 3) A boxer's body crossing between material and spirit. At first, materiality of the gym is external environment and material culture affecting boxers' thinking-behavior unconsciously. In this context, the gym floor makes people acquire fundamental body techniques individually, whereas the ring makes people experience actualization of unconscious body movements in an intersubjective way. Also, the heavy bag is no less important than two artefacts, considering the purpose of boxing is eventually striking a opponent's upper body with clenched fists. Meanwhile, a unique social structure is found through the process of unravelling the history and identity of the gym from materiality. It, then, forces mundane encounters between boxers and non-boxers, and consistently requires boxers to keep their heads fresh. Next, the researcher turns his eyes from the gym to the outside boxing world, where professional boxing, or prizefighting, is a kind of deep play. In this situation, what an earnest professional boxer dreams of is being a world champion. He/she, therefore, should continue to fight to realize the dream, but it can hardly be realized structurally, i.e., most of their dream actually end in tragedy. Professional boxing is a kind of suicide game. Nevertheless, the speculation for the dream goes on and on because, paradoxically, it can hardly be realized. In other words, the most important thing to boxers is how it is perceived at specific events in the process of challenging itself. A form of professional boxing, meanwhile, is very similar to that of sacrifice. A squared ring distinguishes purity from the realm of everyday life, and keeps it tied up to function as an altar. In this context, a boxer becomes a victim as well as a sacrifier for the ritual by transforming his/her reduced body into an immortal body passionately. Moreover, he/she projects his/her body for himself/herself to achieve the ultimate goal of sacrifice, the unity of the sacred and the secular. The researcher finally turns back inside the gym, and discovers bodies of members constantly sweating. They have been taming each other and tamed into the gym because they shares material conditions and social values. It is a process of becoming that links and transforms my body to the other body intersubjectively, i.e., it generates body-relatedness. Body-Speculation, furthermore, is located in the center of this opentype process which a successful initiation and a reciprocal virtuous cycle are the prerequisite to. In a moment of the successful body-speculation actualized on the ring sometimes, each body is wide open to each other, and the nature of boxing, violence, is converted into the experience of pleasure. Consequently, the researcher becomes not only a boxer who embody specific body techniques, but also a member who has a strong emotional attachment to the gym.โ… . ์„œ๋ก  1 1. ๋ฌธ์ œ์ œ๊ธฐ 1 2. ์„ ํ–‰์—ฐ๊ตฌ ๋น„๊ต๊ฒ€ํ†  4 1) ์Šคํฌ์ธ ํ•˜๋Š” ๋ชธ ๊ทธ๋ฆฌ๊ณ  ์ฒด์œก๊ด€ 4 2) ๊ถŒํˆฌํ•˜๋Š” ๋ชธ 9 3. ์—ฐ๊ตฌ๋ฐฉ๋ฒ•๋ก  13 1) ๊ฑฐ์ธ์ฒด์œก๊ด€ 13 2) ๊ถŒํˆฌ์„ ์ˆ˜๋˜๊ธฐ 16 3) ์ž๋ฃŒ์˜ ์ฒ˜๋ฆฌ ๋ฐ ๋…ผ๋ฌธ์˜ ๊ตฌ์„ฑ 20 โ…ก. ๊ฑฐ์ธ๊ถŒํˆฌ์ฒด์œก๊ด€: ๊ตฌ๋ฝ๋ถ€์—์„œ ์ฒด์œก๊ด€๊นŒ์ง€ 23 1. ๋ฌผ์งˆ๊ณผ ์—ญ์‚ฌ 23 1) ๋งˆ๋ฃจ์™€ ๋ง 25 2) ๋นฝ 29 2. ๊ตฌ์กฐ 32 1) ๊ตฌ์กฐ? ๋ฐ˜๊ตฌ์กฐ? 33 2) ๊ตฌ์กฐ ์•ˆ์œผ๋กœ 40 โ…ข. ์„ธ๊ณ„์ฑ”ํ”ผ์–ธ์ด๋ผ๋Š” ๊ฟˆ: ์ฒด์œก๊ด€์— ๊นƒ๋“  ํ˜ผ 46 1. ํ”„๋กœ๊ถŒํˆฌ: ๋ˆ์„ ๊ฑธ๊ณ  ์‹ธ์šฐ๋‹ค 48 1) ํˆฌ๊ธฐ(้ฌชๆŠ€): ๋ˆ„๊ตฐ๊ฐ€๋ฅผ ๋–จ์–ด๋œจ๋ฆฌ๊ธฐ ์œ„ํ•œ ์‹ธ์›€ 49 2) ํˆฌ๊ธฐ(ๆŠ•ๆฉŸ): ํฐ ๊ฒƒ ํ•œ ๋ฐฉ์„ ํ–ฅํ•ด ์ธ์ƒ์„ ๊ฑด๋‹ค๋Š” ๊ฒƒ 54 2. ํ”„๋กœ๊ถŒํˆฌ: ํญ๋ ฅ๊ณผ ํŒŒ๊ดด๋ฅผ ๋“œ๋Ÿฌ๋‚ด๋‹ค 58 1) ์‚ฌ๊ฐ์˜ ๋ง 59 2) ๋ถˆ์‚ฌ์˜ ๋ชธ์— ๋Œ€ํ•œ ์—ด๋ง ๊ทธ๋ฆฌ๊ณ  ํ—๊ทธ๋ฆฌ์ •์‹  62 3) KO 70 โ…ฃ. ๋น„๋ก ์„ธ๊ณ„์ฑ”ํ”ผ์–ธ์ด ์•„๋‹์ง€๋ผ๋„: ์ฒด์œก๊ด€์‚ฌ๋žŒ๋˜๊ธฐ 74 1. ์ž…๋ฌธ 76 1) ๋™์ž‘์—์˜ ์ž…๋ฌธ 77 2) ์žฅ๋น„์—์˜ ์ž…๋ฌธ 79 2. ์„€๋„์šฐ๋ณต์‹ฑ: ๋ชธ์„ ๊ธธ๋“ค์ด๋‹ค 82 1) ๋ชจ๋ฐฉ 83 2) ๋ฐ˜๋ณต 87 3) ๋ฐ˜์„ฑ 90 3. ์ŠคํŒŒ๋ง: ์„œ๋กœ๊ฐ€ ์„œ๋กœ๋ฅผ ๊ธธ๋“ค์ด๋‹ค 93 1) ๋ชธํˆฌ๊ธฐ(ๆŠ•ๆฉŸ): ์‹ธ์›€์„ ๊ฑธ๋‹ค 95 2) ๋ชธํˆฌ๊ธฐ(้ฌชๆŠ€): ํ˜ธํ˜œ์  ๋ชธ์‹ธ์›€ 99 4. ์‰ฌ๋Š” ์‹œ๊ฐ„ 105 โ…ค. ๊ฒฐ๋ก  110 ์ฐธ๊ณ ๋ฌธํ—Œ 115 Abstract 121Maste
