The purpose of this research is to investigate appropriate usage of pansori's method of breathing, sound making, and resonance in order to develop actor's aesthetic voice. Today's theatre no longer see inter-cultural approach as new or experimental, but see it as a part of global current. Actors are required to integrate some global-ness into their acting. It's not enough, however, for actors to equip some cosmopolitan sensibility. More important thing is that they should be able to integrate one's own culture and aesthetic into their performance. Only after acquiring one's own cultural identity, it is possible to step into inter-cultural work. It is fundamental, therefore, for actors to assimilate traditional movement and aesthetic voice. It's been known that traditional Korean voice traits are well preserved in Pansori. In this paper, based upon well-known theories and practices of western voice training, pansori's principles and practices are utilized to bring a new aesthetic voice.

The relationship between the transport of eggs and larvae of Anchovy (Engraulis japonica) and the oceanic condition in the southern sea of Korea was examined on August and November 1996. In summer (August), when the Tsushima Warm Current is strong near to the coast, the warm waters such as warm streamers from the Tsushima Warm Current intrude into the coastal area, and cyclonic circulations are formed. The warm water intrusions also generate wakes around Komun Island, Sori Island and Koje Island. In the coastal area where the warm water intrusions occur, the nutrients, dissolved oxygen, suspended solid and chlorophyll are concentrated in probably relation to the upwelling concerned with this warm streamer and/or the wakes. Anchovy eggs and larvae are transported to the coastal area by the cyclonic circulations. The hatching and growth of anchovy larvae are increased because of high primary production in the cyclonic circulations. However, as the amount of Copepods which are a main food for anchovy larvae decrease in the coastal area, anchovy larvae seem to move to the Isushima Warm Water area for seeking a prey. In autumn (November), the Tsushima Warm Current is far away from the coast. In this season the warm water intrusions almost disappear, and the small scaled frontal eddies are formed between the coastal water and the Tsushima Warm Water. As the surface water moves towards offshore, few anchovy eggs and larvae were sampled in the survey area. Chemical and biological substances are concentrated in the leftdown sides of the small scaled frontal eddies because of eddy formation.

This study was written to examine the acceptance of pansori in movies based on pansori, and to explore changes in modern society's perception and expectations of pansori. A pansori is getting the love of the upper and lower castes in the late Joseon period, but loses the status at the time of the Japanese colonial rule and Korean War. In response, the country designated pansori as an important intangible cultural asset in 1964 to protect the disappearance of pansori. Until the 1980s, however, pansori did not gain popularity by itself. After the 2000s, Pansori tried to breathe in with the contemporary public due to the socio-cultural demand to globalize our culture. And now Pansori is one of the most popular cultures in the world today, as the pop band Feel the Rhythm of KOREA shows. The changing public perception of pansori and its status in modern society can also be seen in the mass media called movies. This study explored the process of this change with six films based on pansori, from "Seopyeonje" directed by Lim Kwon-taek in 1993 to the film "The Singer" in 2020. First, the films "Seopyeonje" and "Hwimori" were produced in the 1990s. Both of these films show the reality of pansori, which has fallen out of public interest due to the crisis of transmission in the early and mid-20th century. And in the midst of that, he captured the scene of a singer struggling fiercely for the artistic completion of Pansori itself. Next, look at the film "Lineage of the Voice" in 2008 and "DURESORI: The Voice of East" in 2012. These two films depict the growth of children who perform art, featuring contemporary children who play pansori and Korean traditional music. Pansori in these films is no longer an old piece of music, nor is it a sublime art that is completed in harsh training. It is only naturally treated as one of the contemporary arts. Finally, "The Sound of a Flower" in 2015 and "The Singer" in 2020. The two films constructed a story from Pansori's history based on the time background of the film during the late Joseon Dynasty, when Pansori was loved the most by the people. This reflects the atmosphere of the times when traditions are used as the subject of cultural content, and shows the changed public perception of pansori and the status of pansori.

하천에서 식생은 하도내 흐름저항과 항력을 증가시켜 유속과 유사이동을 감소시킨다. 유속의 감소로 인해 유사가 퇴적되어 사주 발생이 증가하며 이는 하도 지형변화의 중요한 요인이 된다. 하천내 식생은 하천생물의 서식과 밀접한 관련이 있는 물리적인 서식환경을 변화시키게 된다. 이러한 물리적인 서식환경 변화는 수중음향으로 표현되는 하천의 음환경(Soundscape) 변화로 연결된다. 본 연구는 하천 식생대에서의 수중 음향변화를 식생유무, 수온, 수심에 따라 분석하고 수리학적 특성과의 상관관계를 파악하고자 한다. 실규모 하천 수로에 식생 38 주/$m^2$를 식재하고 1 m정도 성장시킨 후 식생을 완전 침수시켜 $3.2m^3/s$의 유량을 공급하여 유속의 변화와 수중음향을 측정하였다. 오후시간대와 새벽시간대를 이용하여 수온이 다른 조건에서 측정하였고, 수심은 표면 3 cm, 40 cm, 80 cm 깊이에서 각각 측정하였다. 측정지점은 식생구간의 상류지점(A), 식생구간(B), 식생구간의 하류지점(C) 세 곳을 선정하였고, 유속은 micro-ADV, 수중 음향은 Hydrophone을 사용하여 5분간 측정하였다. 측정 주파수 spectrum은 1/3 Octave band로 처리하여 음압을 비교분석하였다. 주파수에 따른 음압을 분석한 결과 측정지점에 관계없이 주로 125 Hz, 315 Hz에서 높게 나타났다. 수심에 따른 음향을 분석한 결과 식생이 없는 상류(A)지점에서는 수중음향의 차이가 크게 나타났으며, 식생지점(B)과 식생이 없는 하류(C)지점에서는 수중음향이 유사하게 나타났다. 이는 식생에 의한 유속의 저하로 인해 흐름이 안정화되어 나타나는 현상으로 판단된다. 수온에 따라서는 식생구간(B)과 하류(C)지점에서 대체로 큰 차이를 보이지 않았으나 상류(A)지점에서는 수온이 높을 때 음압이 더 크게 나타났다. 이는 온도가 높을수록 소리의 전달속도가 더 빨라지기 때문으로 판단된다. 이처럼 식생의 유무와 수심, 온도에 따라 하천의 수리학적 특성이 달라지고 이에 따른 수중음향도 달라지므로 하천의 물리적 서식환경을 평가하기 위한 인자로 수중음향을 활용할 수 있을 것으로 사료된다.

As the first step in research for sound synthesis of Pyungjong, timbre was analyzed by FFT analysis. There was no significant difference in the pitch of scale between modern Pyungjong and western twelve-tone equal temperament scale. The timbre of Pyunjong chagnes over time. When striking Pyunjong, the noises to be generated across all frequencies will disappear in a short period of time, and a unique partial only is left. Then it disappear from the partial of high frequency components in order, and two partials remain at release time. At this time, the beating is occurring by the frequency of the remaining partial. Pyungjong used in this study is relatively a recently manufactured Pyungjong, and for original sound synthesis of Pyungjong, a study of ancient Pyungjong's timbre should be additionally conducted later.

Various room acoustic parameters and their optimal values were proposed and verified as proper interpretations to the listeners' preference of concert hall sounds. However the listening environment has been changed since they were developed, and the listeners' preference may not be the same among countries of different cultural backgrounds. Actual listeners' preference should be applied to the design of a new concert hall. A survey on the listening preference was carried out for 22 music experts. A room acoustical design process was proposed which made the acoustical environment of a concert hall as close to the listeners' preferences.

The bioacoustics generated in urban parks contribute to the overall sound diversity of a city, creating a harmonious acoustic environment and maintaining the balance of the soundscape. However, due to the rapid urbanization process, the acoustic environment in urban parks is continuously deteriorating due to increased noise. In this study, we present an approach to monitoring the acoustic environment of urban parks by analyzing the soundscape of Namsan Urban Natural Park in Seoul. Acoustic data were collected continuously for one month from August 2021 in four facility districts of the study site using autonomous recording units, and a total of 2,784 hours of sound material were obtained. We also compared soundscape characteristics over time in each district using acoustic indices (ACI, ADI, BI, NDSI) representing soundscape complexity, acoustic diversity, degree of bioacoustics, and anthropogenic disturbance. The results showed that acoustic indices related to bioacoustics varied between districts, but most indices showed similar variation patterns due to the influence of anthropogenic sounds. In particular, regional differences closed during periods of high bird activity but not during periods of high human activity. We suggest that considering both acoustic characteristics and multiple acoustic indices is necessary for managing the soundscape of urban parks. The results of this study are expected to provide essential data for assessing the health of urban ecosystems based on soundscapes and to be used for monitoring the acoustic environment of urban parks.
