Since the Korean economic development path has been unique compared to other counties, it is necessary to build an incubation ecosystem matching with unique economic environment in Korea. In order to revive the dynamism of the economy, establishment of the incubator ecosystem should be a policy priority so that ventures with innovative ideas and challenging minds can grow into a global stage. The purpose of this study is to derive the policy implications for establishing ecosystem and infrastructure by comparing to other OECD countries such as US, Israel, Finland, and Japan that can offer meaningful policy implications to Korea. For this purpose, the most appropriate model for explaining the incubation ecosystem in Korea was designed. PCII Model (People, Capital, Incubating, Infra) has 4 elements. It provides a framework for incubation of entrepreneurship, funding for start-up, incubation course, establishment of business foundation infrastructure. The comparative analysis was conducted with 12 sub-items under 4 elements and qualitative and quantitative evaluations were performed for each category. As a result of the comparative analysis, Korea's incubation policy seems to be still in the initial stage in terms of establishment of ecosystem compared to other countries. Therefore, a systematic approach based on the ecosystem model is needed other than the short-term incubation policy.

Studies were carried out using growing to finishing pigs to investigate adequate floor space ($m^2/pig$) in Jeju environment. A randomized block design was used to compare the effect of pig performance on 3 stocking rates (low $0.56 m^2/pig$, medium 0.70 and high 0.90). Liveweight gain and feed intake were measured over a 4 week(Growth stage 1 and Growth stage 2) period or a 3 week(Growth stage 3) period. In growth stage 1 (43 to 65 kg body weight ; BW), daily weight gain was significantly higher in the medium stocking rate than in low or high (P<0.05). However, no significant difference in daily weight gain was found among treatments in growth stage 2(65 to 91 kg) or 3 (91 to 105 kg). Dressing percentage, back fat thickness and carcass grade were also not different (P>0.05). In conclusion, daily weight gain of pigs reared in medium density appeared to be higher than in the other groups during the early growing period which is $0.70m^2/pig$ and similar to that recommended by National Livestock Research Institute, RDA.

We bred a mulberry cultivar named Sangberry, through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at four places(Suwon, Kongju, Jangseong and Sangju) for six years from 2005. This is tetraploidy variety belonging to(Morus alba L.) made by colchicine treatment on growing point of winter buds. Sangberry was high yielding cultivar in fruit productivity by 70% compared to control cultivar "Chungilppong(Morus alba L.)" for four years. Although Sangberry was a little lower in sugar content of mulberry fruits, it contains more bioactive materials like C3G, rutin and amino acids than Chungilppong. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

This study investigated the effect of dietary supplementation with cysteamine hydrochloride (CSH) on the growth performance and nutrient digestibility of broilers. A total of 180 one-day-old male Ross broilers were allotted to one of the three treatment groups with three replications (20 birds per replication). The experimental groups were as follows: control group (basal diet), CSH-1 group (basal diet + 250 mg CSH/kg feed), and CSH-2 group (basal diet + 500 mg CSH/kg feed). During the grower period, feed intake, body weight, average daily gain, feed conversion ratio (FCR), and livability did not show any variation among the treatment groups. On the other hand, a comprehensive evaluation of the finisher period and the entire experiment period found that FCR was significantly improved in CSH-1 and CSH-2 groups as compared to the control group (p<0.05). The dietary supplementation of CSH did not affect the carcass and meat percent (breast and leg muscle). Although there was no significant difference, the digestibility of organic matter tended to be higher in the CSH-2 group than in the control group (p<0.1). This study suggests that a dietary supplement with 250-500 mg/kg CSH can be effective in improving FCR and the digestibility of organic matter in broilers.

The study aimed to investigate the relationship between the rates of leaf senescence and photosynthate translocation at post-anthesis. Seven barley varieties were observed at Suweon in 1988-89. The varieties differed significantly in the number of leaves survived and the rate of photosynthate transolcation with the progress of grain filling. The rate of grain filling was higher in the fast leaf sene-scencing varieties than the slow senescencing ones. There was a close coincidence between the rates of grain filling and $\^$14/c translocation into grains. Photosynthesis was higher in the fast leaf senescencing varieties at early stage of grain filling, but the reverse phenomenon was observed at the late stage of grain filling. The grain yield of fast senescencing varieties was higher than that of slow ones.

국내외 창업 교육 및 창업 현장에 있어 창업자 개인이 아닌 팀 단위의 역량을 중요시하고 있다. 다양한 창업지원 사업에서 팀의 구성에 따라 당락을 결정할 정도로 팀은 창업 초기에 빠르게 나아가기 위한 원동력이자 시너지를 낼 수 있는 중요한 역할을 한다. 또한 창업팀의 활동을 통해 구성원들의 역량이 성장하고 발전할 수 있다고 믿기 때문에 실패를 용인하고 재도전할 기회를 주는 등 사회 분위기도 개선되고 있다. 이러한 시대적 변화에 따라 기존의 창업가(entrepreneur) 중심에서 창업팀(entrepreneurial team) 단위의 연구로 흐름이 변화하고 있으나 이에 대한 연구는 매우 부족한 실정이다. 더욱이 국내 연구에 있어 창업팀에 대한 연구는 초기 단계로 해외의 연구 결과에 의존하고 있어 한국의 창업환경에 맞는 창업팀의 연구가 필요하다. 이러한 연구의 부족은 창업팀이라는 연구 대상이 한정되어있다는 점, 시간의 부족을 겪고 있는 창업 팀원들에게 의미 있는 자료를 끌어내기 어려운 점 등도 애로사항으로 작용하고 있다. 이에 본 연구에서는 창업팀의 특성 중 학습 행동을 유발하는 요인을 찾기 위해 창업팀의 지각된 다양성과 그 다양성을 수용하는 태도에 관하여 연구를 진행하였다. 본 연구의 결과는 다음과 같다. 첫째, 팀원들의 지각된 사회범주 다양성과 지각된 정보다양성이 높을수록 다양성을 수용하고자 하는 의지가 높게 나타났다. 둘째, 정보 다양성과 가치 다양성을 수용하는 태도가 좋을수록 자발적인 학습 행동이 더 많이 발생했다. 셋째, 단순히 다양한 사람들을 섞어 팀을 구성하는 것 자체로만은 학습 행동을 유발하지 않음을 확인하였다. 지각된 사회범주다양성은 정보다양성의 수용태도를 매개로 자발적인 학습 행동에 영향을 미쳤으며, 지각된 정보다양성은 정보다양성과 가치다양성 수용태도를 매개로 학습행동에 유의미한 영향을 주었다. 팀은 긍정적인 영향과 함께 부정적인 영향을 주기도하여 구성원간의 갈등을 야기시키며 창업실패의 요인이 되기도 한다. 본연구는 이러한 팀의 특성을 살펴봄으로서 향 후 창업팀의 육성과 지원 시 팀의 구성원간의 문제에 대한 관심을 유도하고 팀의 특성과 관련한 연구의 확산에 기여할 것으로 보인다.

In this study, we evaluated the salinity tolerance of five forage rice cultivars (Mogwoo, Mogyang, Miwoo, Jowoo, and Yeongwoo) with respect to germination, seedling growth, productivity, and feed values in a reclaimed paddy field in Muan, Korea. We found that the cultivars Mogwoo, Miwoo, Jowoo, and Yeongwoo showed normal germination and seedling growth, even at saline concentrations of between 0.1% and 0.5%, whereas in contrast, there were significant reductions in the germination and seedling growth of Mokyang with an increase in salt concentration. Among the five cultivars assessed, the seedling growth of Mogwoo and Yeongwoo was relatively higher at different salt concentrations in hydroponic and sand cultivation. Furthermore, cultivation of the five cultivars in the reclaimed paddy field with an initial salt concentration of 0.3% revealed that Yeongwoo was relatively superior in terms of yield and feed value. In conclusion, the germination and early growth of Yeongwoo were relatively good at high salt concentrations, and the yield and forage value of this cultivar in a reclaimed paddy field were also relatively superior to those of the other assessed varieties.

최근 에너지 절감과 환경 문제에 대한 관심이 커지면서 친환경적이고 에너지 효율이 높은 LED에 대한 관심이 대두되고 있으며, 국가 저탄소 녹색성장에 맞는 신성장동력산업의 하나로 LED가 선정되어 적극적으로 육성되고 있다. LED를 활용한 조명등은 현재까지 활발한 연구개발이 진행되었으며 백열전구를 능가하는 조명 효율을 확보하여 조명 광원으로서 이용되고 있다. 그런데 선박용 조명등의 경우에는 아직 관련 기술개발이 초기단계에 머물러있어 대부분의 선박들이 기존의 백열등 및 형광등과 같은 조명등을 사용하고 있다. 이러한 유리 조명등은 고소비전력과 제한된 수명에 따른 높은 유지비 및 제품 누수나 파손 등과 같은 안전성의 문제가 있다. 이에 따라 장기적인 관점에서 선박용 LED 조명 등에 대한 기술 개발이 필요할 것으로 보이며 기술 개발을 저해하는 요소인 방열, 가격 등에 대한 추가적인 기술개발이 뒷받침 되어야 할 것으로 보인다. 한국생산기술연구원에서는 부산광역시 지원사업의 일환으로 선박용 LED 조명등을 개발하고 있으며, 체계적인 연구를 위하여 선박용 LED 조명등의 요소기술에 대한 연구동향과 기술특성을 분석하고 있다. 본 논문에서는 선박용 LED 조명등 개발에서 요구되는 요소기술에 대한 기술개발동향을 살펴보고자 한다. 고효율의 선박용 LED 조명등 개발에 필요한 요소기술로는 방열, SMPS, 광학, 제품 내진동, 제품 방수 등의 설계 및 제작기술이 있다. 이러한 요소기술을 알아보고 선박용 LED 조명등 개발의 방향을 제시하고자 한다.
