최근 IT중소기업들은 자체 솔루션의 지속적인 개발을 위해 하드웨어와 인프라 확보에 주력하고 있다. 특히 IT중소기업들은 핵심 기술 확보 에 많은 노력을 들이고 있다. 그러나 이러한 적극적인 경쟁력 확보를 위한 노력에도 불구하고, 기술협력이나 산학협력과 같은 활동을 하지 못해 성장동력을 확보하지 못하고 있다. 이에 본 연구는 하드웨어(인프라), 소프트웨어(기술), 인적역량 등 내부역량과 시장수요, 경쟁강도, 기술수준 등으로 구성된 외부요인 등 IT중소기업의 기술개발 성과를 극대화하는 것을 목적으로 한다. 본 연구는 최신 기술에 대한 신속하고 시기적절한 대응을 위해 기업 간 또는 산학 간 협력을 활용하여 성과를 얻을 수 있는지, 이러한 협력활동을 통해 기술개발 활동이 기업성과에 미치는 영향을 검증하는 것을 목적으로 한다. 또한 협력과 기술개발을 통해 정부의 다자간 기업지원이 기업성과에서 어떻게 규제되는지 검증하고자 한다. 본 연구는 IT중소기업의 대내외적 요인이 기술개발 성과에 미치는 영향에 대한 정부지원의 규제역할을 기술개발을 통해 검증하고자 하였다. 이 밖에도 중소 IT기업의 성장단계인 창업단계와 성장단계에는 다른 차이점이 있을 것으로 판단된다. 이러한 차이를 통해 정부지원 성장단계별 성과에 영향을 미치는 선행요인을 파악한다면 정부지원정책 수립에 시사점을 제시할 수 있을 것이다.

Recently, small and medium-sized IT companies are focusing on securing hardware and infrastructure for continuous development of their own solutions. In particular, small and medium-sized IT companies are making great efforts to secure core technologies. However, despite efforts to secure such active competitiveness, it has not been able to secure growth engines due to the lack of activities such as technology cooperation or industry-academic cooperation. Therefore, this study aims to maximize the technology development performance of IT SMEs, including internal competencies including hardware (infrastructure), software (technology), and human capabilities, and external factors consisting of market demand, intensity of competition, and technology level. The purpose of this study is to verify whether results can be obtained by utilizing cooperation between companies or between industry and academia for a quick and timely response to the latest technologies, and the impact of technology development activities through such cooperation activities on corporate performance. In addition, it is intended to verify how multilateral corporate support from the government is regulated in corporate performance through cooperation and technology development. This study attempted to verify the regulating role of government support in the influence of internal and external factors of IT SMEs on technology development performance through technology development. In addition, it is believed that there will be other differences between the startup stage and the growth stage, which are the growth stages of small and medium IT companies. If the preceding factors influencing the performance of each growth stage in government support are identified through these differences, it will be possible to present implications for the establishment of government support policies.

최근 들어 산업화된 국가에서 승용차의 대수는 비약적으로 증가하고 있으며 이러한 추세는 당분간 지속될 것으로 예상된다. 따라서 사용 후 폐기되는 자동차의 대수 또한 증가할 것이며 이를 재활용하는 문제가 심각히 제기되고 있다. 이러한 문제를 해결하기 위해 2000 년 9 월 유럽에서 제정된 폐기 자동차의 처리에 관한 규제 조항이 독일에서는 2002 년 7 월 1 일부터 법률로서의 효력을 지니게 되었다. 이 법률 제정의 장기적 목표는 차후 10 년 내에 폐 자동차를 처리하는 과정에서 발생하는 잔류물을 현재의 30 Wt.%에서 5 Wt.% 미만으로 줄이는데 있다. 따라서 차후 자동차를 구성하는 재료들에 대한 좀더 혁신적이고도 효율적인 재활용 기술들이 개발될 필요성이 대두되고 있다. 자동차 생산 산업에서 디자인 공정은 계속하여 변화되고 있는 바, 이는 자동차 운행 시 연료를 절감하기 위한 선택적 장치와 새로운 기술적인 해결책에 대한 요구가 강하게 제기되고 있기 때문이다. 따라서 자동차 제조에 사용되는 재료로서 알루미늄과 플라스틱 등과 같은 가벼운 재료들의 사용량은 증가하고 있으며 철과 같은 무거운 재료들은 그 사용량이 점차 감소하고 있다. 그런데 자동차 구성 재료들 가운데 플라스틱류는 흔히 합성된 상태로 사용되고 있으므로 이를 기계적 방법에 의해 각각의 구성 플라스틱 성분으로 분리하기는 불가능하다. 이러한 이유로 인해 폐 자동차를 구성하는 물질들의 효율적 재활용을 위해서는 재활용하기에 용이한 상태로 자동차를 디자인하여 제조하는 것이 필요하다고 할 수 있다. 이와 함께 폐 자동차 재활용 율을 향상시키는데 관한 규제를 만족시키기 위해서는 자동차 생산업체와 재활용 산업체의 통합적 협동체제가 요구된다.

The quantity of passenger cars in industrial countries has been significantly increased in recent years. According to prognoses,this tendency is likely to continue in the forthcoming future. As a direct consequence, an increase of End-of-Life-Vehicles (ELV)will confront us with the problem of “ELV-Recycling”. In order to cope with this situation, the European regulation for the treat-ment of End-of-Life-Vehicles (09/2000) has been transferred to national law in Germany (ELV-Regulation from 1 July 2002).For that reason, there is a need for innovative and more efficient recycling techniques tailored to future materials in automobiles.The design process at automotive industry is continuously changing due to the strong demand on optional equipment and newtechnical solutions for fuel saving. Light materials, such as aluminum and plastics, consequently become more important andcause a decrease of ferrous metals. Since plastic materials are often used as compounds, a separation into initial material typesby means of mechanical recycling methods is not possible. For that reason, efficient recycling can only be realized by introducingrecycling-friendly car designs. In the end an integrated approach of auto makers and recycling industry is of decisive significancefor the fulfillment of future regulations.

The field of recycling for waste electronic components, which is the typical example of an urban mine, requires the development of useful sorting techniques. In this study, a sorter based on image identification by deep learning was developed to select electronic components into four groups. They were recovered from waste printed circuit boards and should be separated to depend on the difference after treatment. The sorter consists of a workstation with GPU, camera, belt conveyor, air compressor. A small piece (less than 3.5 cm) of electronic components on the belt conveyor (belt speed: 6 cm/s) was taken and learned as teaching data. The accuracy of the image identification was 96% as kinds and 99% as groups. The optimum condition of sorting was determined by evaluating accuracies of image identification and recovery rates by blowdown when changing the operating condition such as belt speed and blowdown time of compressed air. Under the optimum condition, the accuracy of image classification in groups was 98.7%. The sorting rate was more than 70%.

Artificial insemination and embryo transfer is one of the most important factors affecting to the production of fawn from deer nuclear transfer in the field of deer farms. This study* was conducted to establish the production technology of nuclear transfered embryo in deer. For estrus synchronization or superovulation tretments in flower deer and elk, each 10 does were inserted into the vagina for 14 days with CIDR (Pfizer New Zealand Ltd., NZ) for elk and Ring-CIDR (Bioculture Co., Ltd., Korea) for flower deer, and then those inserted devices were removed. The estrus synchronization of each 6 does were induced by the intramuscular injection of PGF2α (25 mg/head) and PG600 (hCG 200IU + PMSG 400IU, Intevet, Holland). Then, the superovulation of each 4 does of flower deer and elk was induced by additional injection of FSH (200 mg/ head) twice with an interval of 24 hours , respectively. Follicular oocytes were collected from each 2 does superovulated after 48 hours since the injection of PG600 and FSH. In the meantime, the ovarian response and the number of the collected ovarian follicles were investigated with the surgical operations. As a result, the average number of the collected ovarian follicles were 8.5 and 9.0 in flower deer and elk, respectively. The ovarian follicles collected from each two does were cultured in vitro for 48 hours with m-DMEM medium, and then the cell fusion was carried out after the nuclear transfer by the antler cell. As a result, 5 out of 18 ovarian follicles collected from 2 elk does were reached on the MII stage, but there was no generation resulting from the nuclear transferred embryos by the antler cell after enucleation. In 2 flower does, 7 out of 17 ovarian follicles were reached to the MII stage, but one of them was developed to parthenogenetic embryo as well despite a case of fusion from the nuclear transferred embryo. Embryos were collected in a surgical way on the 7th day after artificial insemination, numbers of average embryos collected were 2.5 and 3.0 in each 2 flower deer and elk does superovulated, respectively. The collected two embryos were transplanted to each 2 does synchronized. As a result, a head of fawn was produced from only one elk doe, where as a head of fawn were delivered from one out of 4 elk does artificial inseminated. Given these findings, we consider that more or less of problems might have occurred in vitro culture system of ovarian follicles in the production of nuclear transfered deer embryos. In addition, the greatest reason why both the aetificial insemination and embryo transfer failed was considered attributable to stress due to anesthesia and catching.
