Our report refers to occidental vocal techniques from Greece until today. It is remarkable that even with poor anatomy knowledge, there were advices on styles given from very early periods, for both church and secular singing. During the 18th century, the names of "vox pectoris", "vox guturris" and "vox capitis" appear, nominations that somehow remain nowadays with great confusion about source of sound production and results of resonance. Vocal occidental styles developed different kinds of requirements from the singers, that had to adapt their vocal Possibilities to them. The same happened with "pop" song. Nowadays, all kinds of singers must have a conscious knowledge of its voice management to prevent vocal disturbances. We consider that the technique is the same, even when the singer has to sing Wagner, Debussy, Sconberg, Piazzola or Gershwin. The big changes occured at resonance levels, and because these different use of the vocal resonators the effects are quite different. In summary, the big differences on classical the effects are quite different. In summary, the big differences on classical and pop song are done on the different use of the resonators and its effects on the vocal tract. "Pop" singers, men and women, should be taught to use both registers, "modal" and "falsetto" to be able to reach the complete range of their songs without any harm to their larynxes. In our opinion, a good singing technique means that it could be adapted to every stylistic need. The same technique is adapted to the popular singer as well. The main difference lays on the use of resonators, pretty strong in the classic singer, weaken in the popular singer, on the volume and on the total extension of the voice. Breathing control, effortless emission and the use of "passage" at the right point should be taught to all singers, regardless of their style. (omitted)

Western classical singing voices are different from those of pop song singer's singing voices as well as traditional Korean singing such as Pansori. We anlalysed the singing voices from three different categories with using free application programs available at the usual smart phones : sound level meter and Spectral View Analyzer and fiberoptic rhinolaryngoscopic evaluation. The intensity of voice produced by a classical western singer was 11 dB louder than that produced by a pop song singer. Source sound, glottic sound, as well as harmonic sound and singing resonant sound (Singer's formant) are much more prominent. When evaluated under video-rhinolaryngoscopy during singing, the resonance cavity especially oropharyngeal cavity and hypopharyngeal cavity are widely opened during singing of the western classical singer than those of the traditional Korean singer's singing. Difference of singing methods including producing the glottal sound, respiration and resonance are discussed. Possible explanation of development of 'Singer's Formant' is discussed.

본 연구에서는 디지털음악시장 성장에 따른 음악소비 환경을 고찰해 보고, 디지털음악 구매환경이 국내 대중가요에 미친 영향을 음악길이와 음악구성의 관점에서 살펴보고 있다. 이를 위해 본 논문에서는 2000년도부터 2011년도까지 대중가요의 항목별 연구조사가 이루어졌으며, 조사항목은 연도별 대중가요의 평균 연주시간과 후렴구까지의 평균 도달시간, 전주, 간주, 후주 출현여부, 그리고 후렴구 선행여부를 다루고 있다. 조사결과 인터넷 음악시장에서의 미리듣기 서비스는 음악길이와 음악구성의 변화를 가져왔으며, 이러한 변화의 결과물로서 후크송의 등장을 낳았다. 이는 소비자의 구매환경이 음악에 영향을 준 사례로, 향후 대중가요는 다운로드 환경에 따른 효과적인 음악 전달기법에 더 집중 할 것으로 판단된다.

2000년대 들어서 가요계는 이전에는 볼 수 없었던 특이한 현상이 발생하였다. 많은 남자 가수들이 똑같은 목소리, 똑같은 창법으로 노래를 부르는 현상이 그것이다. 혹자들은 그것을 "소몰이 창법"이라 이름 붙였는데 당시에는 특이한 목소리로 인해 대중들에게 상당한 인기를 끌었다. 80년도 초 조용필의 "창밖의 여자"가 히트를 하면서 많은 가수들이 조용필의 창법을 익히고자 했던 적은 있었지만 많은 남자 가수들이 똑같은 목소리와 창법으로 앨범까지 발표한 적은 유래가 없었다. 본 연구에서는 "소몰이 창법"이 무엇인지 어떻게 시작 되었는지 또한 발성의 특징은 무엇인지 등에 관한 연구 논문이다.

POP(Point of Production) 시스템은 제조현장에서 발생되는 생산 정보를 실시간으로 수집, 분석하여 현장의 보고 체계를 정형화 시켜준다. 또한 실시간 분석 정보를 통행 생산 이후의 과정(품질관리, 유통, 판매, 생산계획 등)을 기획하고 관리하는데 많은 도움을 준다. 즉, 제조 환경 변화에 따른 생산 지휘 체계를 통제하는 운영 환경을 조성하여 생산성 향상에 크게 기여한다. 이는 특힝 단위 공정의 생산량, 공정의 정확한 측정과 그에 따른 소요시간을 감축하는 장점이 있다. 본 논문에서는 기존의 C/S환경이 아닌 무선인터넷을 이용한 POP시스템을 제시한다.

2020 년대 K-Pop 시장은 보이그룹보다 걸그룹이, 3 세대보다 4 세대가 전반에서 주목받았다. 해당 논문은 걸그룹의 세대가 바뀌기 시작했는지 알아보고자 가사 군집화에 대한 방법과 결과를 제시한다. 2013 년부터 2022 년까지 발표된 47 개 그룹의 1469 곡에 대한 메타정보를 수집하여 가사 정보와 가사 외 메타정보로 분류하여 각각 수치화했다. 가사 정보는 선행연구를 기반으로 단어역문서 빈도 벡터화를 적용한 뒤 상위 벡터 값만 선정하는 전처리를 하였다. 가사 외 메타정보는 가사 정보만 사용했을 때의 편향성을 줄이고 더 좋은 군집화 결과를 보여주기 위해 One-Hot Encoding 으로 전처리하여 적용했다. 전처리된 데이터에 대한 군집화 성능은 Spherical K-Means 의 Silhouette Coefficient, Calinski-Harabasz Score 가 Hierarchical Clustering 에 비해 각각 129%, 45% 더 높았다. 본 연구는 한국 대중가요 발전사와 걸그룹 가사 분석 및 군집화 연구에 기여할 수 있을 것으로 기대된다.

Due in large part to the success of 'Korean Wave' (Hallyu) entertainment commodities, there was much discussion concerning the increasing recognition of Korean culture. With the government's help, South Korean pop culture has spread all over the globe, and Korean businesses have flourished thanks to their global competitiveness. The media in the surrounding areas were quick to catch on, and they all but declared the arrival of Hallyu. Despite a tragic and brutal history of invasions, wars, and dictatorships, South Korea has the 14th largest economy and is the 15th most significant country in terms of soft power. This is largely attributable to the country's leadership in technological and cultural revolutions. The enormous economic and political gains South Korea has experienced from its Hallyu phenomenon remain impressive and even threatening to other countries competing with it for cultural dominance. This is even though media figures in the country must constantly keep in mind new ways to maintain relevance and even enhance their favorability, as pop culture trends are transient and sometimes unpredictable. As South Korean culture spread to the West, Hallyu facilitated the export of several cultural artifacts, including classical music, theater, art, literature, and dance. The Baby Shark music video and song were both created by the Korean business Pink Fong.

Purpose: The purposes of this pilot study were to describe the perceived effectiveness of music therapy for pain control and to identify music preference for postoperative pain and anxiety control in Korean women who had a gynecological surgery. Sample: A convenience sample of 52 women was recruited from a gynecological unit at P University hospital and they were interviewed to assess their perception of music therapy and music preference using a structured study questionnaire. Results: Fifty-six percent of women reported that music therapy would be effective and 96% perceived it would be effective if combined with analgesics. The best music chosen for relieving postoperative pain and anxiety were Korean old pop and ballad song/music followed by Korean religious music, American pop songs, piano music, Korean classic songs, and Orchestra music. Conclusion: There was a cultural difference in music preference for the relief of post-operative pain in this sample. Therefore, effects of music for postoperative pain control need to be determined after considering musical preferences of postoperative women in Korea.

The purpose of this in vitro study was to measure and compare the in vitro micro shear bond strengths of the following dentin bonding systems to different dentin surfaces under simulated pulpal pressure. Occlusal surfaces of 180 extracted human molars were prepared to expose the dentin surface in perpendicular to axis of tooth. Teeth were randomly assigned to 3 equal groups and subdivided into 4 equal groups. 4 adhesive systems(All Bond 2, SEbond, AdheSE, Prompt L-Pop) were used in this study.(omitted)

The aim of this study was to measure and compare the micro shear bond strengths of the following dentin bonding systems to the dentin surfaces under simulated pulpal pressure: All Bond $2^{\circledR},{\;}Second^{\circledR},{\;}AdheSE^{\circledR}$, Adper Prompt $L-Pop^{\circledR}$. The occlusal surfaces of 180 extracted human molars were prepared so the dentin bonding surfaces could be exposed. The teeth were randomly assigned to 3 equal groups of 60 each and subdivided. The dentin surfaces were treated with the above mentioned bonding system and resin composite cylinders were built up under a simulated pulpal pressure when saline (Group II) or diluted bovine serum (Group III) was used as the pulpal fluid. As a control. the same procedures were performed in the dried dentin surfaces (Group I). After one day of storage in water. the micro shear bond strengths were measured using an EZ tester. Group II and III showed significantly lower shear bond strength than Group I statistically (p < 0.05). $SEbond^{\circledR}{\;}and{\;}AdheSE^{\circledR}$ showed no difference among the different dentin condition. In the Adper Prompt $L-Pop^{\circledR}$. a simulated pulpal pressure were applied to the specimens using diluted bovine serum. which showed a higher strength than the specimens in which saline was used (p < 0.05).
