미국 미디어업계와 방탄소년단(BTS)의 상관관계 연구: 빌보드차트의 미디어그룹 체인을 중심으로

박장혁(Park Jang Hyuk) 한국대중음악학회 2021 대중음악 Vol.- No.28

[연구목적] 본 연구에서는 기존 대중음악산업 연구에 있어 상대적으로 부족했던 세계음악시장의 흐름에 대한 통찰력과 예술경영 측면에서의 차기 사업기획 관점을 보강하고자 하였다. 2019년 현재 한국의 음악상품 중 내수전용 상품으로서 한계를 극복하고 해외시장을 아우르는 성장가치를 제시한 그룹 BTS의 사례를 두고 아티스트가 전파하는 메시지와 전략을 소비자가 피동적으로 감흥하여 받아들였다는 기존의 유사연구에 대한 보완책으로 미국의 음악산업을 매개체로 설정해 근원적 원인을 증명하고자 한다. [연구방법] 기존 연구에서 성공사례로 지적된 유튜브와 트위터 등 소셜미디어를 통한 전파효과 외에 더욱 괄목할만한 실적수치상 기폭제 역할을 한 매체와 시기를 추가로 연구하고, 해당 매체의 경영적 환경과 필요전략들을 조사한다. 또한 BTS의 출연 이후 해당 매체의 경영적 성과의 상관관계를 증명함으로서 왜 그들이 케이팝 아티스트에게 문호를 여는 쪽으로 전략을 선회하는 것인지 밝힌다. [연구의 시사점] 아티스트와 소속된 기획사가 가진 전략적 자산과 음악적 소양을 모방해 자신의 성공전략으로 답습하려는 시도는 비단 음악산업만이 아닌 이윤추구를 목적으로 하는 모든 산업의 고질적 병폐이지만, 그로 인한 실패사례의 범람은 안타까운 현실이다. 본 연구는 생산자의 일방적 상품성 강요가 아닌 시장과 매체의 상황을 먼저 이해하고 공감대 생성 과정을 발견하는 선구안을 가지고 시의성 있게 소구를 만드는 문화상품 기획의 한 방법을 제시하는 계기가 될 것이다. To reinforce our insight into the flow of the global music market, which was relatively lacking in the research of the existing pop music industry, and our view of the next business plan in terms of art management. With the case of BTS, a group that presented growth value that transcends the limits and encompasses overseas markets among Korean music products as of 2019, this research aims to prove its fundamental cause by setting up the U.S. music industry as a medium as a supplement to the existing similar research that consumers have received messages and strategies disseminated by artists in a passive way. Therefore, in order to prove the above proposition, the media and timing that played a more significant role in the performance figures are further studied, as well as the dissemination effect through social media such as YouTube and Twitter, which were pointed out as success stories in previous research, and the management environment and necessary strategies of the media are investigated. It also proves the correlation between the media’s management performance after BTS’ appearance, revealing why they are shifting their strategy toward opening doors to K-pop artists. Whenever a new trend emerges in the music market, attempts to imitate the strategic assets and musical qualities of artists and their management agencies as their strategies are a chronic disease of all industries aimed at profit-seeking, not just the music industry, but the resulting flood of failures is a tragic reality. This research will serve as an opportunity to present a method of planning cultural products that make a timely appeal with a pioneering idea of first understanding the situation of markets and media, not the product maker’s unilateral pitching, and discovering the process of generating consensus.

한식의 우수성은 이미 국내외 많은 연구결과로 밝혀진바 있으나 현재까지 한식세계화에 성공하지 못하고 있는 실정이다. 2009년 한식 세계화를 실현한다고 야심찬 계획도 발표하고 1,300억원의 자금도 사용하였지만 한식세계화에 실패하고 말았다. 여러 이유가 있겠지만, 한식의 메뉴의 수는 헤아릴 수 없이 많고 동일한 한식메뉴도 조리사의 조리방법과 식재료의 상태여부에 따라 여러 가지의 맛이 날수 있으며, 이에 따른 표준화 실패와 대표 음식의 잘못된 설정 등이 이유 중의 하나일 것으로 보인다. 이에 대표 음식의 설정에 있어 가장 중요한 것은 외국인들의 입맛이며, 음식의 맛을 결정하는 요인 중 재료도 중요하지만 재료 이전에 중요한것이 양념이다. 한식에 대한 많은 연구가 있었지만 양념에 대한 연구는 극히 미미하여 한식양념에 대한 선호도 연구를 시작하게 되었다. 정확한 통계를 위하여 국내체류1개월 이상의 외국인중 중국인, 일본인을 대상으로 하였고 분석방법은 빈도분석, 기술 분석, 신뢰도 분석, 요인분석, 다중회귀분석, 조절회귀분석 등을 사용하였으며, 체류 기간에 따른 한식 양념선호도에 어떤 조절효과를 주는지를 조사연구하였다. 연구 결과 건강한 식습관 자극적 식습관 집단에서는 맑은 탕 류, 간장류 에 영향을 주는 것으로 나타났고 다양한 식습관집단은 고춧가루/장류에 영향을 주는 것으로 나타났고 체류기간에 따른 조절효과에서는 오직 간장 류에서만 유의한 결과가 나타났다. 이는 한식 세계화 사업에 고춧가루/장류 양념으로 만든 음 식보다는, 간장 류를 기본양념으로 조리된 한식 메뉴 잡채, 불고기, 쇠갈비, 쇠갈비 찜, 간장 게장, 떡갈비, 쇠고기 장조림, 닭찜, 등을 한식 세계화 사업에 우선메뉴로 육성해야 한다는 시사점이 도출되었다. Although the superiority of Korean Food has been come out into the open with many research results around the world it has not been successful globalizing it until now. In 2009 had announced a grand plan to globalize the Korean food and spend & 120,000,000,000. However, the plan had failed. The cause of this failure was putting the base of the plan on the foreigners’ preference of Korean Menu. There are countless Korean food menus and same identical Korean menu could taste different from the chef’s cooking methods and condition of food ingredients. One of the key factors that affect the taste of food is its ingredients. Seasoning plays a big role before ingredients when it comes to the taste. Although there are many studies were conducted on Korean Food, there were not so many studies done on its seasoning so that the research of preference on Korean seasoning has been started. To come up with the accurate statistics, the target segments were Chinese and Japanese among foreigners who stayed over 1 month in Korea. Frequency, descriptive, factor, multi-regression and moderated regression analysis were used in this study and what moderating effect changes on Korean food seasoning preference based on the foreigners length of stay.

According to the Internet Usage Research performed in 2016, the number of internet users and the internet usage have been increasing. Smartphone, compared to the computer, is taking a more dominant role as an internet access device. As the number of smart devices have been increasing, some views that the demand on high-speed internet will decrease; however, Despite the increase in smart devices, the high-speed Internet market is expected to slightly increase for a while due to the speedup of Giga Internet and the growth of the IoT market. As the broadband Internet market saturates, telecom operators are over-competing to win new customers, but if they know the cause of customer exit, it is expected to reduce marketing costs by more effective marketing. In this study, we analyzed the relationship between the cancellation rates of telecommunication products and the factors affecting them by combining the data of 3 cities, Anyang, Gunpo, and Uiwang owned by a telecommunication company with the regional data from KOSIS(Korean Statistical Information Service). Especially, we focused on the assumption that the neighboring areas affect the distribution of the cancellation rates by coupling type, so we conducted spatial cluster analysis on the 3 types of cancellation rates of each region using the spatial analysis tool, SatScan, and analyzed the various relationships between the cancellation rates and the regional data. In the analysis phase, we first summarized the characteristics of the clusters derived by combining spatial information and the cancellation data. Next, based on the results of the cluster analysis, Variance analysis, Correlation analysis, and regression analysis were used to analyze the relationship between the cancellation rates data and regional data. Based on the results of analysis, we proposed appropriate marketing methods according to the region. Unlike previous studies on regional characteristics analysis, In this study has academic differentiation in that it performs clustering based on spatial information so that the regions with similar cancellation types on adjacent regions. In addition, there have been few studies considering the regional characteristics in the previous study on the determinants of subscription to high-speed Internet services, In this study, we tried to analyze the relationship between the clusters and the regional characteristics data, assuming that there are different factors depending on the region. In this study, we tried to get more efficient marketing method considering the characteristics of each region in the new subscription and customer management in high-speed internet. As a result of analysis of variance, it was confirmed that there were significant differences in regional characteristics among the clusters, Correlation analysis shows that there is a stronger correlation the clusters than all region. and Regression analysis was used to analyze the relationship between the cancellation rate and the regional characteristics. As a result, we found that there is a difference in the cancellation rate depending on the regional characteristics, and it is possible to target differentiated marketing each region. As the biggest limitation of this study and it was difficult to obtain enough data to carry out the analyze. In particular, it is difficult to find the variables that represent the regional characteristics in the Dong unit. In other words, most of the data was disclosed to the city rather than the Dong unit, so it was limited to analyze it in detail. The data such as income, card usage information and telecommunications company policies or characteristics that could affect its cause are not available at that time. The most urgent part for a more sophisticated analysis is to obtain the Dong unit data for the regional characteristics. Direction of the next studies be target marketing based on the results. It is also meaningful to analyze the effect of marketing by comparing and an

현재 초고속인터넷 시장에서는 통신 3사의 마케팅 비용이 영업이익의 2배가 넘을 정도로 가입자 확보를 위한 마케팅 경쟁이 치열한 상황이다. 그러나 전체적으로 볼 때는 통신사 상호 간에 가입자가 이동하는 구조이기 때문에 시장에 대한 신규가입자 대비 과다한 마케팅비용이 지출된다고 볼 수 있으며, 마케팅 비용을 절약하기 위해서는 신규가입유치보다 해지 방어에 더욱 노력할 필요가 있다. 현재 해지 방어는 지역적 특성을 고려하지 못하고 전체 지역에 일반적인 마케팅을 시행하고 있으며, 특히 고객의 해지 예측이 잘 이루어지지 못해 어려움을 겪고 있다. 이러한 상황에서 지역의 특성을 고려하여 해지 예측을 보다 정확하게 함으로써 타겟 마케팅을 할 수 있다면 해지 방어에 들어가는 마케팅 비용을 절감할 수 있을 것으로 기대된다. 이를 위해 본 연구에서는 시계열 분석을 통해 초고속인터넷 해지율에 대한 유의미한 예측 가능여부를 확인하고, 해지율 예측 정확도가 높은 최적의 지역 단위를 설정하고자 하였다. 이를 위하여 안양시, 군포시, 의왕시 3개 도시지역의 47개 행정동의 A통신사 전체 해지 데이터를 수집 및 분석하였다. 해지율 예측 및 검증의 단위를 행정구역중심의 구와 각 행정동의 공간정보를 기반으로 한 유사 군집으로 나누어 실시해 비교한 결과, 예측 정확도는 군집, 행정구, 전체 순으로 좋게 나타났으며, 전체적으로 해지율 예측이 유의미하다는 결과를 도출하였다. 이는 지역에서 마케팅을 수행할 때 유사 군집 단위로 해지율을 예측하여 추진하는 것이 효과적일 수 있다는 것을 보여준다. The marketing battle among Korean telecom companies to secure new subscribers has been so fierce that their marketing expense now exceeds operating profit by more than double. The cost of this battle, however, is excessive since it is nothing but a zero-sum game, which each participant’s gain or loss of utility is exactly balanced by the losses or gains of the utility of the other participants. The general marketing strategy of telecom companies is not effective since the companies mainly focus on taking other companies’ customers and do not consider maintaining own subscribers. By increasing the accuracy of measuring termination rate of existing broadband internet users, telecom companies can be benefited saving tremendous amount of money. The purpose of this study is to identify the possibility of forecasting the Broadband internet termination rate by using time series analysis and to set the optimal region units that have condition in which the termination rate can be accurately predicted. The 63,289 termination data of A company were collected from 47 units of administrative dongs, which is similar concept to town U.S., in city of Anyang, Kunpo and Uiwang. These are located in kyonggi-do, Korea. The unit for prediction and verification of termination rate were divided by administrative districts and spatial clustered dongs, and measuring accurate termination rate was better in order of cluster, district, and total unit. Overall, the results revealed that extracting data from spatial cluster is significant in predicting the termination rate. This shows that it may be effective to predict and implement the termination rate in unit of cluster when telecom companies use marketing strategy in different regions.

Considering that rural village had evolved through a long-sustained effort of harmonization with nature. there should be the wisdom not only to reflect the level of rural residents' housing demand. but also to conserve the traditional characteristics of high-valuation in the modem rural housing. In Korea, standard design proposals of rural houses had been made public three times: In 1972, 1984 and 1995. So, firstly, this study analysed the inner-space layouts of design proposals mentioned above, from which changes and problems in the past housing design were derived. And also, through the positive acceptance of residents' opinion living in the houses built by standard design proposals in 1970-1980's. improved design principles and an alternative model were proposed, finally. The inner-space structure of standard design proposals in 1970s was originated from small-scaled and low-priced one, basically under the “open system", In 1980s, the basic design principle changed to the “closed system” in which the living room being the focus of indoor family life. and, in 1990s, progressively, the rural housing developed to the high qualified type by the spatial enlargement and with increased equipments. However, this structural change of rural house brought about the problem of functional separation between farming and daily living activities. In details, limited spaces of multipurpose spaces and sanitary facility would be mentioned as problems for improvement. Conclusively in this study, newly arranged “open system" was recommended, as a basic design principle for the inner space structure formation of rural house, which easily links the constituent inner-house spaces to outer one. Based on this principle, the detailed design criteria was proposed as follows: 1. The living room be directly linked to the front-yard and centrally placed, the additional space of which could be secured for the special family events by the flexibleuse of its adjacent room or by the housing of male quarters(separated from main building quarter). 2. The Kitchen also be directly linked to side-yard and to living room, for the convenience of farming activities and the shortening of path flow of housewife. 3. The expanded toilet-and-bathroom be placed in the directly connected left-hand side to the living room and also be allowed access through multipurpose spaces to out door. 4. The multipurpose spaces be directly connected to the kitchen and the toilet-and-bathroom, of which function would be for undressing of working clothes, quick-washing and ordinary working.

The measurements of velocities of internal flow in a scaled-up nozzle were made by laser Doppler velocimetry in order to clarify the effect of internal flow on the characteristics of fuel spray. The investigated length to diameter ratio(Ud) of the orifice were 1,3.4,5, and 8 and inlet radius to diameter ratio ( r_ο/d) were 0 and 0.5. Mean and fluctuating velocities and discharge coefficients were obtained at various Reynolds number raging between 15,000 and 28,000, and L/d raging between 1 and 8 in sharp and round inlet nozzle. The turbulent intensity and turbulent kinetic energy in a sharp inlet nozzle were higher than that in a round inlet nozzle. For sharp inlet nozzle, fluctuating velocities near exit were decreased with increasing L/d.<br/> <br/> <br/>

Recently the pass-by noise regulation becomes more strict not only domestically but also internationally. Also, the engine performance can be improved by reduction of back pressure in the exhaust system. But it is difficult to be traded off between accoustic and pressure loss. This paper describes the non-linear pulsating flow in the exhaust system by WAVE, the Ricardo, which is non-linear and one-dimensional simulation program. Based on this analysis recommendations are made to be a compromise between accoustic and engine performance. And it is shown that variations of diameter in the exhaust pipe affects overall performance of the exhaust system design.<br/>
