In this paper, we propose an effective Noraebang service algorithm using multicasting technology. The goal of this proposed Noraebang service is to reduce the load of server as well as network resources and to enhance the performance of MOD. The effective Noraebang service algorithm proposes the new method that stores the post-ordered reserve songs in client's buffer in the order of request, not through the network and server, after the completion of the service pre-ordered requested song. The number of channel required in Noraebang service which used this algorithm can be decreased greatly when many songs re reserved, and the post-ordered songs can be serviced at real time by using buffer. The simulation results of this algorithm are confirmed that the performance of the proposed effective Noraebang service system increased significantly.

A research project was conducted to assess the levels of noise exposed to "Noraebang" users and potential hazards to noise-induced hearing loss due to commercial Noraebang noise. A two-way, mixed-factors factorial design was employed for the experiment using independent variables of "noise source" (no- singer, 1-singer, and 2-singer conditions) and "music type" (Trot, Ballad, and Rock music) with 18 normal hearing subjects. Each singer group sang 5 popular songs of each music type in each signing condition, whereas background music was just played for the no-singer condition. For each music played/sung, equivalent continuous sound pressure levels and maximum sound pressure levels were measured for data analysis purposes. Pure-tone audiometry was applied for measuring subjects' hearing threshold levels before and after exposure to Noraebgang noise. The statistical analyses indicate that average continuous noise levels due to Noraebang leisure environment were very serious, especially when two people were singing (higher than 95 dBA). Furthermore, maximum noise levels often exceeded the OSHA's non-premissible 115 dBA level. Worse yet, hearing loss assessment implies that Noraebang facilities may pose a serious threat to noise-induced hearing loss, based on 6-8 dB loss at 125 Hz and 8 dB loss at 4000 Hz after about 1-hour Noraebang noise exposure.

This study analyzes the socio-economical contexts of Japan's Karaoke inflow in Busan of the 1980s, and examines the relationship between Karaoke culture of the 1980s and 'Noraebang' culture of the early 1990s in Busan from the perspective of the SCOT(social construction of technology) theory. By the end of 1970s, Japan's Karaoke was introduced under the contexts of structural transformations of a geisha tourism in the East Asian regions. Karaoke culture in Busan of the 1970s and 1980s has formulated social recognitions of the novelty of Noraebang culture in the 1990s, although it has done so through the ways of misunderstandings and Nationalism.

문화 콘텐츠의 수용 및 체험 방식에는 민족적, 문화적 차이가 존재한다. 일본에서 본격적으로 시작된 가라오케는 한국으로 진출하면서 노래방이라는 밀폐된 공간을 중시하는 형태로, 미국과 유럽에서는 무대라는 열린 공간을 중시하는 형태로 변형되었다. 같은 문화 콘텐츠를 수용하는데도 문화와 민족에 따른 공간적 차이가 관찰된다. 여기서 문화 콘텐츠를 수용하고 그 것을 통해 즐거움을 얻는 과정을 몰입이라고 본다면, 공간과 문화 콘텐츠 사이에는 특별한 관계가 존재한다고 할 수 있다. 본 연구는 이와 같이 공간 사용과 몰입의 상관관계를 실험을 통하여 고찰하고 추후 노래방의 경쟁력 강화 빚 세계화를 위한 효과적인 몰입 요소 도입 및 운용에 적용할 수 있는 연구결과를 제안한다.

요즘 PC를 이용한 여러 가지 사업 아이템들이 상품화되어 쏠아져 나오고 있다. 대표적으로 PC방을 비롯해 가정에서도 고속 인터넷이 가능해지면서 게임뿐만이 아니라 전반적인 생활 자체가 컴퓨터를 통해 이루어져 가고 있다고 해도 과언이 아니다. 흔히 볼 수 있는 노래방 또한 그 예외가 된 수 없다. 현재 노래방에서의 한계점은 신곡이 추가될 때마다 대부분 팁 자체를 교환하거나 추가해줘야 하고 TV 브라운관에 보이는 영상 또한 비디오를 통해 따로 상영해 주어야 한다. 본 논문에서는 PC로 클라이언트-서버 모델을 이용해 노래방 시스템을 구성하여 기존 노래방 시스템의 단점을 극복하고 나아가서 여러 가지 부가 서비스를 지원해 줄 수 있는 인터넷 노래방 시스템의 구현에 대해서 기술한다.

본 논문은 주문형 서비스의 한 분야로서 부족한 네트워크 자원을 고갈시키지 않을 뿐만 아니라 서버의 부하를 크게 경감시켜 MOD의 성능을 최대화시켜 효율적인 노래방 서비스를 위한 새로운 프락시 캐슁을 제안한다. 제안된 프락시 캐슁 구조는 일반적인 unicast 전송으로 멀티미디어 데이터를 서비스 받고 동시에 요청된 데이터가 다른 종단노드(HEN)에 이미 캐슁 되어 있을 경우 후 순위 예약 곡들을 그 종단노드(HEN)로부터 데이터를 전송 받아 스위칭 에이전트(SA)의 스위칭 테이블을 통해 미리 디스크에 저장하여 unicast 채널의 서비스 종료된 다음 후 순위 예약 곡을 서비스 받는 방법을 사용한다. 제안된 분산 프락시 캐슁은 예약 곡목이 많을수록 서버 부하와 과도한 네트워크 트래픽으로 인한 병목현상으로 인한 지연을 크게 감소시킬 수 있고, 시뮬레이션을 통해 성능의 우수함을 확인하였다.

Purpose: The purpose of this study was to examine the effect of parent- adolescent communication on self-concept and problem behavior of adolescents. Method: The participants in this study were 480 students from middle schools in Daejeon City. Data were collected from May 19 to 30, 2008 and analyzed using SPSS WIN 14.0 version. Result: The mean scores for communication with fathers and mothers were 2.98 and 3.35 respectively and for self-concept, 2.80. The highest reported percentage for problem behavior over the past year were going to the noraebang (Karoki) or videobang (PC Cafe) (78.6%). Significant differences were found for the influence of parent-adolescent communication on self-concept and problem behavior. Communication with fathers and with mothers was positive correlated (r=.365, p<.001). The difference in self-concept for communication with fathers was F=60.40, p<.001, and with mothers, F=51.74, p<.001 and for problem behavior, for communication with fathers, F=3.33, p<.05, and with mothers, F=10.05, p<.001. For self-concept and communication with fathers the correlation was r=.512, p<.001, with mothers, r=.453, p<.001 There was a negative correlation between self-concept and problem behavior(r=-.248, p<.001). Conclusion: This results suggest that practical parent-adolescent communication programs should be developed and applied to bolster communication of adolescents with their parents.

Yanji(延吉) city is the district seat of the Yanbian(延邊) Korean Autonomous District where is located in the Jilin(吉林) Province in China, and also the largest city with a population of three hundred sixty thousand, Since the mid-1980s, the inter-exchange and cooperation between Yanbian District and South Korea has been increased rapidly. That draw many scholars' attention to studying Yanbian District and Korean Chinese as a research theme for area studies. Unfortunately they neglect the study of the commerce and service industry in Yanbian city, which has indicated its rapid growth by the market economic policy of China, and an inter-exchange between Korean Chinese and Korean. The purpose of this study is to provide an information to many Korean potential investors for an investment strategy of the commerce and service industry in Yanji city. In order to do so, this study consists of three major steps. First of all. we analyzed the regional structure and locational characteristics of the commerce and service industry in Yanji City. Secondly, we investigated the characteristics of consumers behavior toward purchasing goods and service facilities. Finally, we supplied the proper businesses and location information for investment to Korean firms according to the results that identified above. In conclusion, we suggest that the proper businesses to invest are department store, retail clothing store, shoes store, cosmetics store, electronics and home appliances store, oversea branch offices of trading companies, Korean-style restaurant, hotel, nightclubs, Korean-style music room(Noraebang), travel agencies, beauty parlors, video rooms, electronic games, and so on. We also suggest that the proper locational areas to invest those businesses are the core area of the commerce and service industry in Yanji, where are Xinxing(新興) 3-zone and Jinxue(進學) 2-zone expressed in the Yanji city figure.
