홈 네트워크에서 효율적인 다중 멀티미디어 스트림 서비스를 지원하기 위해서는 가능한 여러 문제점들을 고려해야 한다. 그 중에서도 네트워크 대역폭 부족 상황을 대처하는 것은 가장 어려운 문제 중에 하나이다. 본 논문에서는 IEEE1394 기반 홈 네트워크에서 실시간 대역폭 관리 서비스를 미들웨어 레벨에서 운용해 대역폭 부족 상황을 대처하는 방안을 살펴본다. 대역폭 부족 상태를 대처하고 버스 사용 효율을 높이기 위해서, 제안하는 서비스는 두 가지 방법을 이용한다. 첫째는 대역폭 상태를 지속적으로 감시하여 특정 서비스가 과도하게 점유한 잉여 대역폭을 되돌려 받는다. 둘째는 등시성 스트림(IS) 스케줄러를 이용해 우선순위에 따라 스트림 서비스들을 통제하는 것이다. 제안한 서비스는 프로토타입 스트림 관리 미들웨어로 구현하여 간단한 IEEE1394 네트워크 상에서 시험하였다. In order to support multiple multimedia streaming services in home networks, many critical issues must be considered. In addition, handling the shortage of network bandwidth is one of the most significant and complicated issues. In this paper, real-time bandwidth management service is suggested as a solution to the problem regarding the IEEE1394-based home network. In order to handle the shortage of network bandwidth and to enhance the bus utilization rate, the proposed service combines two methods. First, the bus bandwidth management function determines the state of the network bandwidth and restores the residual bandwidth, which is excessively occupied by a streaming service, to the available free bandwidth. Second, the Isochronous Streaming (IS) Scheduler manages all streaming services according to priority. In order to test the proposed service, we implemented a prototype steaming management middleware and evaluated it by using the IEEE1394 network test-bed.

This study aimed to examine Korean men`s experiences of work-family balance in dual income families with children under six years of age. We focused on identifying the difficulty of balancing work and family considering their individual, social, and cultural conditions. The method was a qualitative study involving two in-depth interviews with each of 12 men, and analyzing the data through the grounded theory approach. From the results, a model of men`s work-family experience was constructed. It demonstrates the central phenomena (difficulties of balancing), the causal conditions (lacking time for family, seeking support from the employer, and learning husband`s roles insufficiently), the contextual conditions (remaining paternalism and changing husband`s roles), the intervening conditions (workplace, childcare support, and wife characteristics), and strategies (help from relatives, utilizing daycare centers, controlling birth, managing work conditions, and using family polices). We clarify the overall picture of working and family life experiences, and also show how men deal with their problems in their circumstances by balancing working and family life. In conclusion, males have difficulty participating in family life autonomously because of having less decision-making power than the wife. Moreover, the great responsibilities of the breadwinner disturb the work-family balance. Men devote themselves to working to hold a job instead of spending time with their family. However, they ultimately value work-family balance with respect to ‘keeping a peaceful family life’.
