This study was carried out to define gazelle industry through preceded research for gazelle firm & gazelle region, in order to discover high-growth industries. Gazelle industry is 'employees per company is more than ten people, and over the past five years, within top 10% by Birch employment growth index'. According to the definition of gazelle industry, Chungnam gazelle 105 industries were chosen. Then, analyzed whether Chungnam gazelle industries has competitiveness compared with nation and each city of Chungnam. In addition, typology to industrial development stage was devised by developing of business scale quotient(BQ) and industrial growth rate(IG). And development strategies of Chungnam gazelle industries was proposed case by industrial development stage.

The purpose of this study is to examine the characteristics and industrial structure and to present a future vision through analysis of industrial agglomeration, growth, and industrial efficiency targeting the Chungnam display industry nurtured by regional industrial policies since 2002. The industrial scale and aggregate status were analyzed through the business scale quotient and location quotient, and the growth and pace of structural change in the industry were analyzed through the industrial growth rate and change of industrial structure. Analysis results found the display industry shows its solid status based on industrial agglomeration. The RLQ, added value ratio, and employment coefficient have a relatively high comparative advantage. However, the growth rate has declined, and the pace of structural change has become lower. The regional competitiveness has been deteriorating. It is necessary to develop strategies to help the industry evolve into a convergence display industry to secure competitiveness by forming value chains. The regional industrial policy 'Regional Innovation Growth Plan' should be utilized to foster local industries that consider the regional characteristics and development directions and to promote the shared growth of related subsidiary industries through fostering specialized complexes for materials, parts, and equipment.

An experiment was conducted to investigate the effects of supplemental copper or/and zinc methionine chelates(Cu-Met or/and Zn-Met) on the performance, nutrient digestibility, serum IgG level, gizzard erosion, and the contents of Cu and Zn in liver and excreta of broiler chickens. One thousand d-old broiler chickens (Ross$^{(R)}$) were assigned to 4 treatments: control, 100 ppm Cu in methionine chelate(Cu-Met), 100 ppm Zn in methionine chelate(Zn-Met) and 100 ppm Cu plus 100 ppm Zn in methionine chelate(Cu-Zn-Met). Each treatment had five replications of 50 (25 male + 25 female) birds each. Average weight gains of chicks fed chelated Cu or/and Zn were significantly higher than that of chicks fed the control (P<0.05). Moreover, feed conversion rates of chicks were better in the chicks fed chelated Cu or/and Zn than in the chicks fed the control (P<0.05). The birds fed the chelated Cu and Zn(Cu-Zn-Met) tended to perform the best growth rate and feed conversion rate. Nutrient digestibilities were not affected by the dietary treatments. Serum IgG level of chicks fed Cu-Zn-Met was significantly higher than that of chicks fed the control (P<0.05). Gizzard erosion index was not significantly different among the treatments. The contents of Cu and Zn in liver were not significantly affected by the dietary treatments. The excreta contents of Cu or/and Zn were significantly high in the birds fed supplementary Cu or/and Zn. It was concluded that dietary supplementation of Cu or/and Zn in methionine chelated form improved growth and feed conversion efficiency of broilers.

This study investigates the technical level and industrial structure for the case of the Gazelle industry in Chungnam Province. As a results of the empirical study, the Gazelle industry of Chungnam Province shows a competitive position in terms of scale and growth capacity, which. in turn, provides income and tax collection effects due to the high level of industrial efficiency. Among the Gazelle industry of Chungnam Province, low-level technology industry, compared to high and middle-level technology industries, accelerates higher level of agglomeration and industrial growth, which provides a rapid change of industrial structure of the province. Theses research results imply that research and development investment in the Gazelle industry is essential and industrial development strategy should be conducted via step-by-step with business scale quotient (BQ) and industrial growth rate (IG). Meanwhile, there should be a serious policy review whether low-level technology industry is better off for the province compared to high and middle-level technology industries. This study expects that regional industrial policy applying the concept of Gazelle industry can accelerate regional development since the Gazelle industry contributes to the high level of income growth and employment creation.

An experiment was conducted to investigate the effects of supplementary Blended essential oil(CRINA$^{\circledR}$) on the performance, nutrient availability, fatty acid composition of leg muscle, small intestinal microflora and blood parameters in broiler chickens. One thousand unsexed day-old broiler chickens were assigned to five treatments : control(T1), 5ppm avilamycin(starter diet) & 5ppm flavomycin(grower diet) T2, 5ppm avilamycin(starter diet) & 50ppm CRINA$^{\circledR}$(grower diet) T3, 50ppm CRINA$^{\circledR}$(starter & grower diet) T4, 50ppm CRINA$^{\circledR}$+ 500ppm lactic acid$^{\circledR}$ (starter & grower diet) T5. Each treatment had four replications of 50 birds each. Growth performance was significantly improved by dietary supplements(T2-T5). There were no significant differences among treatment T2, T3, T4 and T5. Feed intake was not significantly different among treatments. Dietary supplementation of CRINA$^{\circledR}$(T3, T4, T5) resulted in significant(p〈0.05) improvement in feed/gain(F/G) during finishing period (4-5weeks). The birds fed CRINA$^{\circledR}$ supplemented diet(T4) showed significantly(p〈0.05) higher availability of crude fat, methionine and methionine + cystine than those fed antibiotics supplemented diet(T2). Mortality was not significantly affected by treatments. The colony forming unit(CFU) of E.coli in small intestinal content was significantly lower in antibiotics & CRINA$^{\circledR}$(T3) compared to CRINA$^{\circledR}$ treatment(T4)(P〈0.05). CFU of Cl. perfringens was low in CRINA$^{\circledR}$(T4) but not different significantly with other treatments. Serum triglyceride level of birds fed CRINA$^{\circledR}$ + lactic acid diet(T5) was significantly lower(p〈0.05) than those fed antibiotics supplemented diet(T2). Cholesterol level of the birds fed antibiotics(T2) or CRINA$^{\circledR}$ + lactic acid supplemented diet(T5) was significantly higher(p〈0.05) than other treatments. HDL level of birds fed control diet was significantly lower(p〈0.05) than that of others. The levels of serum IgG were not significantly different among treatments. Major fatty acids composition of leg muscle fat was significantly influenced by treatments. Control group showed significantly higher palmitic acid(C$_{16:0}$) and steraric acid(C$_{18:0}$) content than other treatments(p〈0.05). Content of oleic acid(C$_{18:1}$), however, was significantly lower in the control than others treatments. Content of linolenic acid(C$_{18:3}$) was significantly higher in CRINA$^{\circledR}$+ lactic acid(T5) than antibiotics & CRINA$^{\circledR}$(T3) treatments. Total saturated fatty acids content was higher and total unsaturated fatty acids were lower in the leg muscle fat of the control than that of other treatments. It is concluded that CRINA$^{\circledR}$ supplementation improved growth rate and F/G ratio in broilers. The combination of CRINA$^{\circledR}$ with either antibiotics or lactic acid did not show any additive or synergistic effects in broiler chickens .
