과학기술의 발전에 따라 첨단과학기술 산업인 항공우주 산업도 발전하고 있으며, 항공우주산업 분야에서의 산업간 융합이 증가하는 추세이다. 항공우주 산업은 대표적인 첨단 과학기술 산업으로써, 전자·통신 분야뿐만이 아닌 타산업의 비약적인 발전을 가져오고 있다. 이에 따라 항공우주산업의 융합 활성화를 위하여 연구동향을 파악하고자 한다. 분석을 위해 항공 논문들을 수집하였으며, 수집된 논문은 토픽 모델링과 네트워크 분석을 통해 기술을 추출하고 산업간 연관성을 분석한다. 이로써 항공우주산업의 활성화 정책수립에 기여할 수 있을 것으로 기대된다.

This research was conducted to investigate the effects on the growth performance, feed intake, feed conversion and carcass characteristics of the growing-finishing pigs with 4 kinds of feed additives wmposed of probiotics which were used in the swine farm of ChejuDo area. Two experiments were conducted in the W-farm (high energy and protein, Spring) and B-farm(low energy and protein, Summer). The experiment was designed with 5 treatments according to the kinds of additives used(T; control, A; Biopro, B; Ataphon-o, C; YC-2000, D; Photo-plus). In the W-farm experiment, 75 three-way crossbred pigs weighing average 38㎏ were randomized with 3 replications for 102 days. In the B-farm experiment, 105 three-way crossbred pigs weighing average 33㎏ were randomized with 3 replications for 103 days. Daily weight gains were increased a little by supplementing the probiotics in comparison with control(T). But there were not significant differences among the treated goups. There were no differences in feed intake among treatments in the W-farm. But in the B-farm a little inaease in feed intake was observed in the probiotics group. However, feed conversion rates were somewhat improved by the probiotics compared to control(T) in the W-farm, but they were not significantly different. Carcass weight and percentage were increased a little in the pigs fed the probiotics compared to the control (T). The pigs fed probiotics A and B showed apparently higher carcass weights and rates without statistical differences compared to the others. In the W-farm the symptom of overfattening was observed in the control(T) and the treatment C. However, the backfat thicknesses of the treatment A, B and D were suitable. In the B-farm the backfat thicknesses of the control(T) and the treatment C were poor and scanty, but those of the treatment A, B and D resulted in suitable thickness. According to the carcass Bade analysis, the carcass grades of the experimental pigs showed the following order; A $gt; B $gt; D $gt; C $gt; Control(T). The improvement of carcass grade was made by the dietary probiotics. According to the result of the taste panel evaluation, the dietary probiotics made a good effect on the meat colour and marbling, tenderness, meat flavour and meat juiciness of the pork.
