The Binary Scheduling Wheel(BSW) algorithm was proposed to carry on manage buffer efficiently at implementing of WRR scheduler. But, BSW algorithm cause serous performance degradation of cell delay and maximum queue length because it allocates more weight than the weight allocated actually in VC and could not serve cell if the VC queue is empty. In this paper, we propose new BSW of the old BSW structure. Also, we develop a cell scheduling algorithm which is suitable for the new BSW structure. The proposed BSW structure and the developed algorithm are capable of maintaining the allocated weight of each VC correctly, and decrease average cell delay and average buffer length by serving other VC cell when the selected VC queue is empty, and increase cell service ratio as a whole. The evaluation results show that the proposed structure can implement WRR algorithm more efficiently than the old BSW.

This paper attempts to suggest an alternative regional policy of agricultural restructuring and strategies for food processing industry support in Chonbuk. Chonbuk is on the threshold of serious restructuring against the trade liberalization. The increasing pressure of agricultural import liberalization from abroad has given great burden to Chonbuk agricultural sector which has lagged behind the average growth of national agriculture. The challange is to find an orderly process of restructuring that will achieve a more improvement of productivity and stability. This study suggests diversification out of rice monoculture into a multicrop enterprise system as an essential component of agricultural restructuring, induced by the changing relative profitability of rice and nonrice enterprise. The potential for diversification out of rice depends on both physical and economic factors. The profitability of diversification is constrained by both markets and physical infrastructure. Successful transition from rice monoculture to a rice based farming system in Chonbuk should be induced by market forces. The Korean dietary pattern has been changed drastically in parallel with economic growth and the share of processed foods in the daily diet has been increasing over the last decade. Thus, the Chonbuk local government should encourage the growth of the food industry which is projected to continue to grow in the comming years. The structure of the food industry in Korea is lather unique in that small-sized firms produce a greater part of the total output. One major problem facing the small firms in the food industry is that they are often too small to exploit economies of scale in production and marketing. Some small-sized companies are being gradually phased out of business due to shortage of labor and high cost seructure. The expansion of export market is expected to accelerate the development of food industry. In order to keep ahead of competition in export markets, Chonbuk local government should undertake an important role in establishing food combinat to adopt a restructuring and upgrading strategies for food processing industry support.
