A dynamic simulation program of a catenary-pantograph system including tunnel section and transient section is developed in this study. The simulation program can accommodate for the pantograph of two panheads and three d.o.f model. Using the developed program, the dynamic characteristics with a SCHUNK'S WBL 85-PANTOGRAPH are analyzed at the conventional TAEBAEK line and its tunnel section when the catenary system is supported by a tunnel bracket. The simulation results show that the variation of contact force md uplift displacement is allowable in general section and the entrance and exit of a tunnel, but the uplift displacement and the separation ratio within tunnel section is difficult to allow.

세계화가 진행됨에 따라 다양한 문화의 음악을 즐기는 사람들이 늘어나고, 해외 팬들이 외국 노래를 이해하고 따라 부를 수 있는 접근성을 확보하는 것이 중요해졌다. 이를 위해 본 논문에서는 노래 가사 데이터에 특화된 영어-한국어 번역 모델 리리코(LyriKOR)를 제시한다. 리리코는 영어 노래를 한국어로 번역하여 그 의미를 담아낼 뿐만 아니라, 번역 결과물이 원곡의 선율과 리듬에 어느 정도 부합하도록 하여 한국어로 바로 따라 부를 수 있도록 하는 것을 목표로 한다. 이를 위해 번역과 음절 조정의 두 단계(two-stage)를 거쳐 제한된 데이터로 음절 정렬된 번역 모델을 훈련하는 새로운 방법을 소개한다. 모델 코드는 여기에서 볼 수 있다.

This is a paper that examines the meaning and changes of how Dalgang Song, a parenting song, is accepted in pansori works and how it plays a role in the narrative of the work. In Chapter 2, Compared the lyrics of Dalgang-Dalgang in actual parenting scene and Dalgang-Dalgang in Pansori's work. As a result, the songs in Pansori, show some differences in lyrics, but most of them kept the narrative structure intact. Among them, Gangreung-maehwa-ga maintained the phrase "Dalgang-Dalgang" in front and back, making the least changes. Simcheong-ga and Jeokbyeok-ga maintained their epic structures, but the the front and the rear phrase turned into a "Uh huh, Doong doong". And Dalgang-Dalgang was sung mostly by its mother or grandmother at the actual parenting scene, but the song in Pansori, was all sung by men. Dalgang song in Pansori, had a mostly Gyemyeon melody due to the genre characteristics of Pansori. Also Dalgang-Dalgang for actual parenting, was sung with a leisurely, soft beat. But Dalgang song in Pansori's works were sung rhythmical with Jungjungmori rhythm or Jajinmori rhythm to maximize joy. In Chapter 3, I discussed the roles and meanings of Dalgang song contained in Pansori. Dalgang-Dalgang of Simcheong-ga appeared in the crucial process of Sim Hak-kyu's return to will of life through Simcheong after the death of his wife. In Jeokbyeok-ga, Dalgang song also appeared as a tool to recall the happy memories with his son. On the other hand, Dalgang-Dalgang of Gangreung-maehwa-ga played a role of expressing affection for relationships between men and women, not between parents and children. This is beyond the original meaning of parenting, which means the hedonistic and excessive affection of Mr. Gol. The desire to change a relationship between a man and a woman into between parents and children is also found in Kim Yeon-soo's Chunhyang-ga. This change is an example of how the role and meaning of Dalgang song has changed dramatically as it was inserted into pansori. And the reason why Dalgang-Dalgang was so important in the narrative of Pansori was because of The lyrics of the song contain the love of the baby.

2003년 11월에 개봉된 영화<올드보이>는, 으로 유명해진 박찬욱 감독의 복수극 3부작의 제2편으로 알려진 작품이다. 3부작의 첫 편인 <복수는 나의 것>의 연장선상에서 이 영화를 예견했던 평론가들과 관객들은 전작이 가지지 못했던 상업성까지 겸비한 이 영화의 독특한 스타일과장르, 그리고 신선한 소재에 감탄하고 열광했다.영화<올드보이>는 기본적으로 상업적으로 ‘잘만들어진(well-made)’ 영화이다. 말하고자 하는 것도 명징(明澄)해 관객들을 혼란스럽거나 지루하지 않게 만들며, ‘멜로’적요소와‘느와르’적요소, 거기에‘미스테리’요소까지 들어 있어 관객들의 시선을 쉴틈없이 붙잡아 둔다. 화려한 색감과 음울하면서도 압도적인 오리지널 사운드 트랙의 선율, 신선한 촬영기법(특히, 영화 속 최민식의 3분동안의 롱테이크‘장도리 액션’장면은 이 영화의 압권이다), 그리고중간 중간 보이는 블랙 코미디의 요소까지. 물론 이 영화를‘잘만들어지게’만든데에는 최민식이라는 배우의 뛰어난 연기력과 그외의 배우들의 호연도 큰몫을 했다. 그래서 관객들은 이 영화가 숨겨둔 ‘비밀’의 섬뜩함과 불편함에도 불구하고 이영화를 ‘재미있게’ 보러 왔다. 그 덕분에 <올드보이>는 흥행면에서 꽤 큰 성공을 거두어 300만명 이상의 관객을 동원했다. 그리고 2004년 5월 화제를 뿌리며 칸느 영화제에서 심사위원대상이라는 쾌거를 거둔다. 뿐만 아니라 2003년 청룡영화상, 2004년 대한민국영화대상 등 국내영화제에서도<올드보이>의 활약은 대단했다. 2003년흥행과 작품성 모두에서 인정을 받은<살인의추억>의 자리를 이 영화가 물려 받고 있다고 할만하다. 한마디로 말해, 우리가 늘 주목하는‘잘된콘텐츠’의 전형적인 예인 것이다. 바로 그 지점 때문에 우리는 이 영화에 대해 이야기할 필요가 생긴다.

The relationships between the ability to understand changes in meaning depending on the prosody of spoken words and the ability to perceive pitch and melodic contour in cochlear implants (CI) recipients were examined. Fifteen postlingual CI recipients were measured in terms of speech prosody perception, speech perception, pitch discrimination (PD), and melody contour identification (MCI). The speech prosody perception test consists of words with positive (PW) and neutral meaning (NW). Participants were asked to identify the meaning of words depending on the conditions of positive and negative prosody. The MCI consists of subtests 1 and 2 with different chance levels to choose. Then, the relationships between speech prosody perception, speech perception, PD, and MCI performance were analyzed. There was a significant difference in identifying the meaning of words expressed in a different prosody between the PW and NW conditions. Speech prosody perception showed a significant correlation with MCI 1 while there was no significant relationship with speech perception. Although speech perception may be possible after CI, limited spoken word comprehension due to decreased sensitivity for prosodic changes may persist in CI recipients. In addition, there was a limitation in perception of melodic contour change compared to pitch discrimination, which is related to speech prosody perception.

In music theory, the triton is defined as a musical interval composed of three adjacent whole tones(or six semitones), which generates a harmonic and melodic dissonance. The triton paradox is an auditory illusion which is heard as ascending by some people and as descending by others. In this paper we examine an emerging non-static biometric technique that aims to identify users based on analyzing uniqueness and consistency through the user experiences. We also propose some authentication schemes which provides protection against key logging, shoulder surfing, and brute force attacks.

Manjungpan Chunhyangga is established by Manjung Kim Sohee. She selectively chose and arranged the songs by Jung Jungryeol, Song Mangap, Jung Eungmin, Kim Yeonsoo, Park Dongsil, and Jung Kwangsil. Kim Sohee once stated that while a major section of Chunhyangga is based on the songs by Jung Jungryeol, Song Mangap, Jung Eungmin, and Kim Yeonsoo, the whole part of Okjungga is derived from Park Dongsil. However, there is not much material that will provide enough information with regard to what musical characteristics Park Dongsilje Chunhyangga possessed. Under the circumstances, the voice of Park Dongsilje, left by Kim Sohee, triggers curiosity on Park Dongsilje Chunhyangga. It can also be construed that there must be a good reason for choosing Park Dongsilje for Okjungga, unlike other parts. Therefore, this paper attempted to find out what the unique features of Par Dongsilje are and what the reasons behind Kim Sohee's musical choice were through comparison and analysis of Kim Sohee's musical features in Okjungga. The following are the results. Firstly, Okjungga is a created verse by its nature and it does not possess specific features to a school. Therefore, the reason for choosing Park Dongsilje could have been based on musical reason rather than verse. Secondly, the lyrics of Park Dongsilje Okjungga is closer to that of Song Mangap rather than that of Jung Jungryeolje. It can be argued that it falls between the two of them. Thirdly, the tone and melody of Park Dongsilje Okjungga falls in the middle section of Dongpyenje and Supyenje. Fourthly, the analysis of Jinyangjo rhythm out of the whole Manjungpan Chunhyangga shows that there are slight differences among Song Mangapje, Jung Jungryeolje, and Jung Eungminje. Park Dongsilje is very unique in the sense that it does not use utbutim in gyemyeonjo part in Manjungpan Chunhyangga. Park Dongsilje Okjungga is a song to which the tone, melody, and sigimsae of Supyeonje is added to lyric butimsae of Dongpyeonje. It can be seemed as simple and less sophisticated because, with its simple lyric butimsae, it shows a less complicated tone utilization rather than Jung Jungryeol. With lighter decoration of music, feelings can be conveyed more directly. That is probably why Kim Sohee commented on Park Dongsilje Chunhyangga that it is the most mournful song for Chunhyang and it is the song that moves anyone who listens to the song. Consequently, Kim Sohee accepted Park Dongsilje Okjungga and she created different feelings to Manjungpan Chunhyangga which has repeatedly displayed the color of Jung Jungryeol. Combining the lyric addition of Dongpyeon style and the melody of Supyeon style can crated a different language.
