K-POP 아이돌그룹에 일본인 멤버가 있음의 의의 -소속사의 전략, 그룹내 문화교류, 일본인 팬들의 수용을 중심으로-

본고에서는 K-POP 아이돌그룹에 일본인 멤버가 있음의 의의에 대하여 ‘소속사의 전략’, ‘그룹내 문화교류’, ‘일본인 팬들의 수용’이라는 세 가지 관점으로 고찰했다. 그 결과, 소속사는 그룹을 다국적화 시킴으로서 해외에서 인기를 얻으려고 하는데, 특히 일본에 있어서는 일본 기업과 제휴하거나 일본어로 정보발신하는 등 적극적인 프로모션을 하고 있다고 확인되었다. K-POP 아이돌그룹에 속하는 일본인 멤버는 한국 문화에 동화한 경우가 많지만, 그 그룹이 일본에서 활동하는 때에는 다른 멤버를 도와주는 장면이 보이었다. 또 일본 방문을 통하여 한국인 멤버는 외국인 멤버의 마음이 이해되는 외에 그 가족들과의 사이에는 ‘이문화를 가지면서 친한 사람’ 끼리의 교류가 생기고, 서로의 문화 이해로 이어져 있었다. 게다가 일본인 멤버는 K-POP과 일본인 팬들의 다리를 놓는 역할도 한다. 라이브 방송 때 방송 내용이나 한국 문화를 설명하는 사례가 가끔 있었다. V LIVE 구독자수를 보아도 이런 활동이나 일본인 멤버가 존재함이 일본인 팬 획득·정착으로 이어지는 것이 밝혀졌다. 이렇게 해서 K-POP에 접근한 일본인들이 최근 일본인 멤버가 없는 그룹에도 관심을 가지게 되는 것도 주목되는 현상이다. This paper discussed what Japanese members of K-POP idol groups bring to them from three perspectives: strategies of agencies, cultural exchange within groups, and acceptance of Japanese fans. We found that agencies aim to make the groups popular abroad by making it multinational. Especially in Japan, they are actively promoting the groups by cooperating with Japanese companies or sending information in Japanese. Japanese members often assimilate into Korean culture. However, when the groups visit Japan, they help other members act in Japan. Korean members understand how foreign members feel by being in a foreign country. In addition, families of Japanese members interact other members as ‘friendly people with a different culture’, and it leads to understanding of each other's culture. Japanese members also play the role as a bridge between K-POP and Japanese fans. Japanese members sometimes explain the broadcasting contents and Korean culture for Japanese fans during live broadcasting. The number of V LIVE subscribers reveals that these activities or the presence of Japanese members leads to the acquisition and settlement of Japanese fans. It is also remarkable that the Japanese who have approached K-POP in this way become interested in groups that have no Japanese members these days.

Auxiliary resonant snubber inverters (RSIs) have been proposed as a solution of demands for inverter, which are high efficiency and low EMI. In RSI, zero voltage switching (ZVS) on the inverter main switches is achieved by use of the auxiliary circuit; however, additional conduction loss increases simultaneously. The operating frequency of the auxiliary circuit in RSI can be reduced to a half of switching transition of a main switch when lossless snubber commutation, in which ZVS can be achieved without using auxiliary circuit by using output current, is used. As a result, additional conduction loss can be suppressed. However, in this scheme, ZVS turn-on on main switch is failed near zero output current when dead-time was constant. As a solution for this problem, adjustable dead-time control scheme for RSI has been proposed. Adjustable dead-time control has not been applied to a rectifier with auxiliary resonant snubber circuit ?auxiliary resonant snubber rectifier (RSR)in the previous work. Thus, adjustable dead-time control is applied to RSR in this paper. This paper shows a control scheme for RSR. Moreover, the effectiveness of adjustable dead-time control by comparing between the adjustable and the fixed dead-time control is described.

Purpose: Sialolithiasis is one of the most prevalent large obstructive disorders of the submandibular glands. The aim of this study was to investigate submandibular sialolithiasis with computed tomography (CT) and scintigraphy, with a particular focus on the relationship between CT values of the submandibular glands and their excretion rate. Materials and Methods: Fifteen patients with submandibular sialolithiasis who underwent CT and salivary gland scintigraphy were included in this study. The relationship between the CT values of submandibular glands with and without sialoliths and salivary gland excretion measured using salivary gland scintigraphy was statistically analyzed. Dynamic images were recorded on the computer at 1 frame per 20 seconds. The salivary gland excretion fraction was defined as A (before stimulation test [counts/frame]) / B (after stimulation test [counts/frame]) using time-activity curves. Results: The CT values in the submandibular glands with and without sialoliths was $9.9{\pm}44.9$ Hounsfield units(HU) and $34.2{\pm}21.8HU$, respectively (P=.233). Regarding the salivary gland excretion fraction using scintigraphy, the A/B value in the submandibular glands with sialoliths ($1.09{\pm}0.23$) was significantly lower than in the submandibular glands without sialoliths($1.99{\pm}0.57$, P=.000). Conclusion: Assessments of the CT values and the salivary gland excretion fraction using scintigraphy in the submandibular glands seem to be useful tools evaluating submandibular sialolithiasis.

This study reports a visual observation of the formation and growth of ionic semiclathrate hydrate on the surface of a Tetrabutylammonium bromide (TBAB) aqueous solution and CO2+N2 gas mixture. The composition of CO2+N2 gas mixture was 20 : 80. The experimental temperature range was from 280 K to 290 K, under the pressures of 2.3MPa and 4.7MPa, at wTBAB=0.10 and wTBAB=0.40, where wTBAB denotes the mass fraction of TBAB in the aqueous solution. At wTBAB=0.40, the hydrate crystals were initially observed to grow within the droplet, and followed by lateral growth at the droplet surface; but at wTBAB=0.10, the hydrate crystals grew exclusively in the liquid phase and did not cover the droplet surface. Two types of different crystals with different sizes were clearly observed.

Since many years ago and in spite of the existence of national regulations and international conventions ratified by the countries that are conformed the Central American Region (CAR), the seagoing maritime sector of this Region, has developed its activity without any type of safety measures. Therefore, a large number of people are known to die, disappear and suffer from serious injuries each year. These maritime casualties devastate the families affected by these events, and severely impact the local social and economic well-being. While all these accidents occurred in this Region, non government or any other official records are available recording these casualties. Due to the lack of any historical written reports about maritime casualties occurred in this Region, the compilation of this type of accidents information and data was carried out directly by the researchers in the field. Also, all the information about the CAR Maritime Organization Components was too compiled by the authors from the respective National Maritimes Authorities. From the compiled information was elaborated the CAR maritime casualties data base and from the analysis of the above data base were determined the main causes of the maritime accidents occurred in the CAR. The lack of safety measures onboard and the ignorance of the presence and influence of atmospheric phenomena were among main factors that had been caused the maritime casualties in this Region. By other hand, from the analysis of the CAR maritime organization components, the existence of one level of organization very similar among them was determinate. The objective of this research was to analyze the role of the CAR maritime organization in the prevention of the occurrence of maritime casualties. The results of this study provides general understanding of the causes of this type of accidents in the CAR and basis for support in improving safety navigation system and measures so that the number of fatalities and maritime accidents may be reduced in the future.
