본 연구에서는 2011년 7월 발효되는 한·EU FTA가 경북 지역에 미치는 경제적 파급효과와 이에 대한 산업부문별 대응방안을 제시하였다. 한·EU FTA 발효 이후 경북 지역의 섬유, 자동차부품, IT 및 가전제품의 수출은 다소 증가하고, 철강 분야는 별로 영향을 받지 않으며, 정밀 기계와 정밀 화학, 돼지고기와 낙농제품 등에서 다소 타격을 받을 것으로 전망된다. 한-EU FTA는 일부 농축산물, 낙농업, 과수 부문에서 피해가 우려되지만, 경북의 지역내총샌산, 고용, 제조업 생산을 증대시키고 소비자 후생을 중가시킬 것으로 분석되었다. 이 연구에서는 경북 지역경제와 주요 산업에 미치는 영향과 지역산업계의 대응과제를 제시하였는데, 지역 산업들은 해당 업종별로 구체적인 대응방안을 세워 추진해야 한다. This paper intends to analyze the impacts of an FTA with European Union(EU) on major industries in Gyeongbuk region and derive policy measures for the regional government and those industries. The study begins with a comprehensive analysis on the trade relations between EU and Gyeongbuk region and investigates how the Korea-EU FTA affects the regional economy and major industries in Gyeongbuk. An FTA with EU would have positive impacts on major industries such as textile/clothing, electronics, steel/metal, and automobile components in the region. However, the Korea-EU FTA would adversely affects major products such as livestock/fruits/dairy products, precision machinery, precision chemical products in the region. Therefore, the regional government and industries should derive policy measures to make use of the FTA with EU as well as to minimize material injuries on the agriculture/livestock and machinery industries in Gyeongbuk region.

This experiment was conducted to determine the effect of ammonia treated rice straw on nutritive value and rumen characteristics. Rice straw was treated with aqueous NH₄OH to supply 40g NH₃ Kg^(-1) straw dry matter. The reaction time with ammonia was 6 weeks at room temperature. The results are as follows: Crude protein content increased more than 2 times by treatment, and the NDF content was decreased about 4.7%. The effect of ammoniation was the important factor in enhancing IVDMD. Ammoniation resulted in the significant improvements in intake, digestbility and nutritional quality. Improvements in nitrogen and sulfur retention was significant with treated straw. Also, Molar proportions of acetate increased (P$lt;.01) and butyrate decreased (P$lt;.01) with ammoniation. In conclusion, ammoniation is a simple and effective method of improving the feeding value of rice straw.

This experiment was designed to study the effect of carbohydrate sources with some different processes on the utilization of amino acids in the intestine as well as amino acid flow at the abomasum. The carbohydrate sources were cracked corn, whole barley, rolled barley and steamrolled barley, and the 20% of total nitrogen was replaced by the urea. The results obtained are as follows; 1) For the quantities of TAA-N, EAA-N and NEAA-N passing the abomasum, it resulted not significantly in increased for the steamrolled barley diet. The amounts of TAA-N and NEAAN digested postruminally were significantly lower at the feeding of cracked corn diet (P$lt;.05). The mean values for the proportionate disappearance of apparently digested TAA-N, EAAN, and NEAA-N within the intestine for four diets were 79.74±2.53, 79.23±2.40, and 80.62±2.91, respectively. 2) There were no significant differences (P$lt;0.5) for individual amino acid composition (g/100g DM digesta) in abomasum. There were significant differences for the quantities of amino acid passing abomasum on the GLU, PRO, VAL, LEU, PHE, LYS, and ARG at the feeding of steamrolled barley (P$lt;.05). The amounts of each amino acid in abomasal digesta, expressed as a proportion of the amounts ingested for the diets, showed that there were net gains of EAA with exception of cystine and NEAA. 3) Within the intestine of sheep, there was significant loss of amino acids, such as SER, GLU, GLY, ISL, LEU, PHE, LYS (P$lt;.05), and PRO, VAL, and ARG (P$lt;.01). The mean values of the proportionate losses of methionine and phenylalanine were 0.748±0.015, and 0.805±0.032.

Fifteen Korean native cattle, averaging 128㎏ of initial body weight, were utilized to evaluate the effects of SMS on growing performance and digestibility of nufrients, protozoal population in the rumen and some mineral balance in sheep. The concentrates were given the amount of 1% of body weight and each roughage (SMS, rice straw, rice straw-pellet) of 2%o of body weight. NaCl and water were available at all times. After 48weeks of experimental peroid, the final body weight of SMS group was significantly higher compared with the other roughage groups (P $lt; .05). Daily weight gain of SMS, rice straw and pellet group was 0.90, 0.69, and 0.81㎏, respectively. In sheep experiment, the nutrient utilization for SMS tended to increase mostly, while the crude protein digestibility for the pellet group was significantly decreased. The rumen pH value for SMS group tended to be slightly lower compared to the other groups, and the concentration of individual VFAs was higher at the SMS group. Especially, the butyric acid for SMS was doubled in value than that of other roughage. Total protozoal count in the rumen fluid was higher at SMS group, followed by straw and pellet group (P $lt; .01). And Entodiniomorphs was predominated species, especially Entodinium. SMS But Holotrichs in me or straw was more frequently observed. Absorption% of intake of Mg, Na, K for the SMS were 48.18, 64.37, and 61.83, and these of the other groups were lower. As compared to the high intake of Na for pellet group, the retained amount was fairly low as were the other minerals. Nitrogen retention for pellet group was lower than that of the other groups (P $lt; .01).

This experiment was carried out to study effects of crude soybean lecithin addition on digestibility of ration components, ruminal characteristics, fermentation of long-chain fatty acids in the rumen, and composition of fatty acids in blood lipid. The results obtained are summarized as follows: 1. The digestibility of OM, protein, ether extract, fiber, ADF, NDF and energy were improved with 4% lecithin, and especially ether extract was significantly (P$lt;.01) more digested than the control. 2. The digestibilities of major fatty acids were not greatly affected by the inclusion of lecithin. However, the unsatutated fatty acids were more digestible than the saturated fatty acids regardless of the treatments. 3. The ruminal pH at the 8% level was slightly lower than at the 0 or 4% levels. The ruminal viscosity was greatly influenced by the addition of lecithin. The ruminal viscosity was much lower at the 4 and 8% levels (6.0-9.0 cp) compared to the control (13.0-16.0 cp). 4. The total VFA concentration tended to be slightly declined with increasing lecithin. In the molar proportions of individual VFAs, the addition of lecithin resulted in a high increase in proportion of propionic acid and n-valeric acid. The acetic acid production declined greatly as the crude soybean lecithin increased. 5. The ruminal ammonia concentration was increased with lecithin supplementation. 6. The stearic acid in the rumen fluid was quantitatively the most important fatty acid, followed by palmitic and oleic acids although the difference in the proportions among treatments existed. The fatty acids in the faeces ware predominated stearic acid followed by palmitic acid, and unsaturated fatty acids were at low percentage. 7. The concentration of free fatty acid in blood lipid increased with lecithin addition. In the fatty acid composition of blood, the stearic acid was quantitatively the most proportion, followed by oleic acid and palmitic acid. 8. The above results indicate that the inclusion of crude lecithin can be well utilized by ruminants in view of the. profitable effects in the digestibility and the production of individual VFAs.

This experiment was conducted to examine the effects of carbohydrate source with some different process on the rumen microbial protein synthesis as well as nitrogen flow at the abomasum. The carbohydrate sources were cracked corn, whole barley, rolled barley and steamrolled barley, and the 20% of total nitrogen was replaced by the urea. The used forage was wild grass hay and the feeding ratio of concentrate to forage was about 77: 23. The results obtained are as follows; 1) No significant difference (P$gt;.05) between diets was observed from the mean values of pH and total VFA of rolled and steamrolled barly diets. The molar proportions of propionate, iso-butyrate and butyrate were significant (P$lt;.05). The released ammonia contents for cracked corn and steamrolled barley were lower than those of other diets. 2) The dilution rates of rumen liquid and particulate and rumen volume were not significant between the diets. And the outflow of liquid from the rumen was higher at steamrolled barley by 284㎖/hr. 3) Flow of OM at the abomasum and the faeces resulted in a little decrease when sheep was fed corn diet. There was a significant difference for apparent OM digestibility (P$lt;.05). 4) The nitrogen passing abomasum (P$lt;.05) and NAN at abomasum were increased for the steamrolled barley diet. The ratio of bacterial N to NAN at abomasum was 0.7980, 0.7059, 0.7612 and 0.7323 for the cracked corn, whole barley, rolled barley and steamrolled barley, respectively. The efficiencies of microbial protein synthesis (g N/㎏ OMTDR) microbial were 25.01, 24.04, 24.90, and 28.41 g-N, respectively.

대경권 친환경에너지산업 집적 특성에 관한 연구

윤칠석(Chil Seok Yoon) 한국지역지리학회 2010 한국지역지리학회지 Vol.16 No.6

본 연구는 대구경북에 소재한 친환경에너지기업을 사례로 입지현황 및 집적 특성을 클러스터 관점에서 분석해 봄으로써 친환경에너지산업육성을 위한 정책입안의 대안적 기초자료를 제공하고자 시도되었다. 주된 자료는 2010년 6월 21일에서 7월 23일에 걸쳐 기업체와 환경전문가를 대상으로 한 설문조사의 결과이다. 대구경북의 친환경에너지기업은 주로 경북의 포항과 구미, 대구의 달서구에 집적되어 있다. 대경권 친환경에너지기업 존립기반의 핵심적 요소는 지역 내 대기업의 입지와 동종기업의 기술적, 지리적 근접성을 들 수 있다. 즉 대경권은 대기업이 신재생에너지를 신수종사업으로 채택하고 설립한 기업이 중심이며 주된 입지요인은 관련 원자재 확보보다는 교통 및 통신의 편리성, 지역 수요자의 높은 품질 기대 수준, 기술적, 지리적 근접성, 지역 동종기업과 경쟁이며, 현재 애로사항으로는 기술 및 연구개발 금융지원과 전문인력 양성 지원이었다. 향후 대경권 친환경에너지산업의 정책에 있어서는 종래의 인프라 구축지원 혹은 세제 혜택 등에 초점을 맞춘 지원 정책에서 과감히 탈피하여 기업수요에 기반한 기술개발 관련 금융지원, 지역 전문인력양성 및 종사자 재교육 프로그램도입과 친환경에너지산업 분야의 정책과제 발굴에 대경권 친환경에너지산업 육성정책의 초점을 두어야 할 것이다. The purpose of this study is to examine the geographical distribution and the clustering characteristics as an industrial cluster in order to provide alternative fundamental data for the preparation of the policies to facilitate the development of the Green Energy Industry. The main source of the data in this study is the outcome of a survey conducted to the firms and environment specialist from June 21st, 2010 to July 23rd, 2010. The Green Energy related companies in Daegyeong region are clustered around Pohang and Gumi, Gyeongbuk, and Dalseo District of Daegu Metropolitan City. The core element of the sustainability of the Green Energy Industry in the region is the inducement of the large-scale corporate presence in the region as well as the technical and geographical proximity. That is, the fact that there are sister companies established by the large scale corporate Daegyeong region as they have chosen this field for their new drive for growth. The major location factors are proximity, higher quality expectations from the local demands, technical availability, and competition with other companies of the same industry in the region, rather than the availability of the raw material. And the choke points for these companies are the financial support of R&D and the policy support of specialist training. The policy to facilitate the development of the industry in question in Daegyeong region, therefore, should shift from its previous focuses on infrastructure building and taxation benefits to financial supports for the technical research, human resource development in response to the needs of the companies. Also, programs to support the proficiency training for the already-hired work forces and development of new policies for the Green Energy Industry are needed to be introduced for the development of the Green Energy Industry in Daegyeong region.
