무대에서 노래한다는 것은 개인연습을 하는 것과는 전혀 다르다. 관객과 호흡 할 수 있는 여유나 그 날의 날씨, 장비 셋팅, 자신의 컨디션이 주는 요인에 대해 확실한 이해가 있어야 한다. 이 연구는 보컬들이 무대에서 노래할 때 겪게 되는 여러 가지 상황 중에서 날씨의 변화에 따른 적응법과 무대장치에 따른 적응방법을 연구한다.

In this paper, we proposed a method for extracting predominant melody of polyphonic music based on harmonic structure. Harmonic structure is an important feature parameter of monophonic signal that has spectral peaks at the integer multiples of its fundamental frequency. We extract all fundamental frequency candidates contained in the polyphonic signal by verifying the required condition of harmonic structure. Then, we combine those harmonic peaks corresponding to each extracted fundamental frequency and assign a rank to each after calculating its harmonic average energy. We run pitch tracking based on the rank of extracted fundamental frequency and continuity of fundamental frequency, and determine the predominant melody. For the query by singing/humming (QbSH) task, we proposed Dynamic Time Warping (DTW) based matching engine. Our system reduces false alarm by combining the distances of multiple DTW processes. To improve the performance, we introduced the asymmetric sense, pitch level compensation, and distance intransitiveness to DTW algorithm.

According to the material about the analysis of digital consumers' lifestyle in Korea published at the end of 2016, 100% had experienced a smartphone before, and 91% had joined in digital communications. Among digital contents, 85.5% had experienced music, and 78.6% had used TV contents before. Also, SNS utility rate equaled 83.3%, and the Facebook utility rate of those in the 10's and 20's exceeded 80%. It means that it is necessary to conduct research on SNS utility in broadcasts. Based on the results of operating KBS Facebook accounts, this paper aims to compare the reaches of entertainment, drama, and culture genres and analyze correlation between the reaches and 'like' friends on Facebook and also correlation between the reaches and ratings.To address the goal, among the Facebook mentions operated within a year, 2016, this researcher analyzed 2,526 mentions to publicize entertainment, drama, and culture genres and the results of 834 million reaches and also used the data of original broadcasts' ratings. To analyze the data, this study employed SPSS Ver. 18.0 to perform the independent sample t-test and Pearson's correlation analysis. The conference interval is set as 95%, and p<0.05 is regarded to be statistically significant. According to the results, more reaches are found in entertainment, drama, and culture genres in order, and it is found to have strongly positive correlation with the frequency of 'like's. The reaches and ratings have no correlation, and there is no statistical significance found in it. It is expected that the results of this study can be applied to publicize programs efficiently for broadcasting.

The research is centered towards analyzing the differentiation of the characteristics and organization of programming strategy and channel positioning by selecting Korean International Public Relations Broadcasting Stations Arirang TV and KBS World. According to the results, Arirang TV positions Korean culture content-implied educational programs as their strategy while KBS World places the main programs of KBS1, 2TV with many entertainment programs such as dramas and entertainment shows. Arirang TV's programming strategy is well-fulfilling the purpose of promoting Korea's culture contents by organizing their programming with documentaries, tourist information, and daily living information. On the other hand, KBS World works as the agent of the spread of the Korean Wave by filling their program with dramas and K-pop programs such as . Due to the difference in programming strategy of these two broadcasting stations, Arirang TV has positioned itself as a diplomatic channel to spread Korean culture and KBS World a channel representing the Korean Wave. However, there are problems of inefficiency due to recurrent investments because of the fact that both broadcasting stations' programming strategy is to promote Korean culture and spread the Korean Wave by aiming similar targets such as foreigners or overseas Koreans.

This study is a metaverse platform design study to support indie musicians' performances in a virtual environment. Interest in indie music has increased, but the number of accessible platforms has decreased after COVID-19. As a result of a survey of low-budget indie musicians, many people found it difficult to perform on stage due to lack of money and time. As the metaverse, which enables new social and economic activities, emerges, this study sought to contribute to resolving these difficulties by developing a prototype of a platform that allows performances in a metaverse environment beyond the existing stage environment. We conducted a prototype test of the platform developed for indie musicians and discovered the potential of a metaverse virtual space for indie musicians.

Purpose: The purpose of this study is to provide a basis for establishing a policy to promote the export of Korean goods through the economic ripple effect of the Korean Wave. From 2001 to 2017, cultural goods exports and consumer goods exports data to 102 countries were used to estimate the effect of cultural goods exports on domestic consumer goods exports. Research design, data and methodology: Based on the Gravity Model, we analyzed the effects of domestic film, publishing, music, broadcasting, clothing, cosmetics, processed food, IT products, and automobiles on the export of consumer goods. Results: The empirical analysis estimated the trade creation effect of exports of cultural products driving exports of consumer goods and found that a 1% increase in exports of cultural products increased 0.136% in exports of consumer goods. Conclusions: The average rate of change in consumer goods exports due to changes in cultural product exports was 22.44, which could be interpreted as an increase of $2,244 in exports of consumer goods such as IT products, cosmetics, clothing, and processed foods. According to the analysis of export-driven effects of each consumer item by dividing cultural products by sector, the effects of export of processed foods, clothing, cosmetics, IT products, and film, music, publishing exports were statistically significant.

최근 방송 사용 음악에 대한 저작권료 배분의 투명성을 위하여 방송음악 식별 기술에 대한 관심이 커지고 있다. 음악 DNA라 부르는 음악의 신호적 특징을 이용하는 기존의 음악식별 기술이 존재하지만, 방송 배경음악의 특성으로 인해 방송 사용 음악 식별에 그대로 활용하기는 어렵다. 방송이나 영화에 사용되는 배경음악은 우리가 일상생활에서 주로 소비하는 가요나 팝과 같은 음악과 비교하여 그 수가 매우 많고, 하나의 음악 테마에 대하여 조금씩 다르게 편곡한 유사 음악들이 다수 존재한다. 즉, 방송 배경음악을 식별을 위해서는 유사한 음악이 많은 대규모 음악 DB를 대상으로 잡음이 섞여 있는 음악을 식별하여야 한다. 한편, 대부분의 음악 식별 시스템은 빠른 검색을 위하여 모든 데이터를 메모리에 올려두고 처리하는 방식으로 동작하는데, 대규모 음악 DB를 지원하기 위해서는 시스템 자원을 적게 사용하면서도 식별율이 떨어지지 않는 특징 추출 파라미터와 인덱싱 파라미터를 찾는 것이 중요하다. 본 논문에서는 이러한 요구사항을 만족하는 배경음악 특징의 추출방법과 이 특징을 효율적으로 검색할 수 있도록 하는 검색 구조를 기술한다.

This study examined determinants of diversity in cultural consumption among people in their 20s. The main results are following; firstly, this study explored determinants of diversity in nine cultural consumption. The results showed that diversity of cultural consumption was determined by three factors such as current interests in cultural fields, content preferences based on broadcasting genres, and income. Although current interests in cultural fields and content preferences based on broadcasting genres were positively correlated to cultural consumption, income was negatively correlated. Next, this study examined diversity in cultural consumption in terms of two separate orientations such as highbrow and mass cultures. The results showed that diversity of highbrow culture was determined by current interests in cultural fields, content preferences based on broadcasting genres and income. Also, diversity of mass culture was determined by current interests in cultural fields, content preferences based on broadcasting genres and education period for classic music including opera and chorus.
