An Efficient Multicast Routing Algorithm for Packet-Switched Networks
Chung, Sung-Jin,Hong, Sung-Pil,Park, Bum Hwan 한국경영과학회 1998 한국경영과학회 학술대회논문집 Vol.- No.2
This paper has a dual purpose. First, we consider a relaxation algorithm which seems to be particularly suitable for multicasting routing problems. We show that the algorithm has polynomial complexity. Second, to measure the quality of solutions in comparison to the optimal solutions over a wide range of network sizes for which the computation of the optimal costs is too excessive, we also propose a random graph generation scheme in which an asymptotic lower bound on the expected optimal cost can be computed as a function of network node size.

The sugar composition of inulo-oligosaccharides produced from inulin consisted of mainly inulobiose and inulotriose in almost equal amounts with a bacterial endoinulinase either as a soluble enzyme or as intact cells. Inulobiose was the major product with immobilized enzyme or cells. The composition in fructo-oligosaccharides which had similar structure to inulo-oligosaccharides showed no significant difference irrespective of enzyme sources and reaction modes applied.

The purpose of this study is firstly to analyze the status and attitudes of freshmen class of 1988 and secondly through this analysis to make a plan that helps improve freshmen's adjustment to university life. The main information analyzed in this study was collected by a questionnaire. Informations asked are as follows: (1)backgrounds of each freshman and his/her family, (2) freshmen's attitudes and expetcations toward the university and the major field of study, (3) freshmen's attitudes toward the Korean society, (4) some prolems facing freshmen and choice of areas of occupational career. The findings of this study are summarized as follows: 1. Most of freshmen select a field of study withut any informations about that subject of study. Also most of freshmen did not select their major field of study accordings to their intersts or aptitudes. but they chose their field of study by considering possibility of success in admission competition. 2. In the same manner of other years the economic problems are the most important concern of freshmen. Most of freshmen are hard up for school expense and want to earn their school expense. 3. Most of Freshmen expect a culture, a dilettante life, a building up their character and the formation of wide personal relation. Specially most of freshmen want to professor's humanistic guidance. 4. Most of freshmen want to participate in student circle activity. 5. Most of freshmen see positively and are proud of Pusan National University. 6. About 50% of freshmen regard a university as a preparatory stage of occupational career. 7. Freshmen's attitude toward Korean society was optimistic, but some of them pointed out the corruption of the society and the problems of economy and domestic politics. And most of freshmen point out that Pusan is somewhat backward in modern culture.

Al/CFRP laminates were made with alternating Al7075 sheets and CFRP prepregs by co-curing process. There are many factors influencing the performances of the laminate. We made it changing volume fraction and fiber orientation of CFRP. In this paper, tensile and 3-point bending tests were conducted to investigate the influence of the volume fraction and fiber orientation of CFRP on tensile and flexural properties.
