  • HgCdTe는 고성능 적외선 센서 재료로 널리 사용되고 있다. 현재 상용화된 HgCdTe 소재는 통상적으로 액상 에피 성장법으로 제조 되고 있다. 액상 에피 성장법에 의해 제조된 HgCdTe는 갓 성장 상태에서 많은 양의 Hg-공공(vacancy)을 함유하게 되며 적외선 소자의 응용을 위해서는 이러한 Hg-공공을 채우기 위한 Hg-분위기 열처리 공정을 거치게 된다. 열처리 혹은 성장 공정 시 HgCdTe 소재 내에 발생하는 마이크로 혹은 나노스케일의 조성의 변화는 응력의 집중을 가져오며 이는 전자, 혹은 정공의 응집을 가져와 소자 동작의 불균일성을 야기한다. 본 연구에서는 액상 에피 성장법으로 성장 된 HgCdTe 박막내에 존재하는 응력의 분포와 Hg-공공을 채우기 위한 열처리 과정에서 생성 또는 소멸되는 응력의 변화를 Geometric phase strain 분석법으로 관찰하였다. 분석결과, 응력의 집중된 부분은 주로 성장 시 석출된 Te 및 Hg-공공으로 부터 기인함을 확인하였다. Hg-분위기 열처리를 통하여 석출된 Te 제거 및 Hg-공공의 감소를 확인하였고 이에 따른 응력의 집중 부분도 해소됨을 알 수 있었다.

  • The purpose of this research is to conduct the empirical analysis of the short- and long-term causal relationship between public R&D investment, corporate R&D investment, and university R&D investment on economic growth in Korea. To this end, based on the time series data from 1976 to 2020, a causality test was conducted through the unit root test, cointegration test, and vector error correction model (VECM). As a result, it was found that there is a long-run equilibrium relationship between economic growth in Korea, public R&D investment, corporate R&D investment, and university R&D investment, in which a causal relationship exists in the long run. Also, while public R&D investment has a short-term effect on economic growth, corporate and university R&D investment does not have a short-term effect on economic growth. In addition, the results shows that there is a bidirectional causal relationship between economic growth and public R&D investment, corporate R&D investment and public R&D investment, and university R&D investment and public R&D investment in the short term. Through this research, it was empirically found that a highly mutual relationship exists between public R&D investment, corporate R&D investment, university R&D investment and economic growth. In order to increase the ripple effect of R&D investment on economic growth in the future, R&D investment between universities and corporations should be mutually promoted, and R&D investment by corporations should have a positive effect on public R&D investment so that public R&D investment can contribute to future economic growth.

  • 국가에너지 총 사용량의 건물에 대한 에너지 부문은 약 28%를 차지하고 있으며, 서울시의 경우는 약 58%가 건물 에너지 소비로 사용되고 있다. 기후변화 대응 및 온실가스 감축을 위하여 서울시는 '친환경 건축기준'을 발표하고 조례 시행 중에 있다. 공공건물에서의 에너지 절감은 어떤 효력을 가지고 있을까. 이에 대해 전문가들은 공공건물의 에너지 손실을 최소화하고 에너지 이용효율을 극대화함으로써, 국가 예산을 절감할 수 있을 뿐 아니라 나아가 이산화탄소 배출량 감축에 기여하면서 미래성장동력인 녹색 성장을 활성화하는데 밑바탕 이 될 것으로 내다보고 있다. 이와 관련해 국내 공공건물 에너지 정책과 해외 공공건물의 에너지 정책 사례를 살펴보고, 나아가 에너지절감 기술의 적용 방안을 소개한다.

  • The importance of industrial policy and innovation policy perspectives on public procurement has recently been highlighted. In particular, there have been discussions and studies on whether public procurement directly affects the growth and innovation of SMEs. As an extension of this study, this study analyzes whether the age of a firm moderating the effect of public procurement on growth among the characteristics of firms participating in public procurement. The analysis data was constructed by matching the financial data of about 1,247 firms designated as excellent products by the Public Procurement Service(PPS) from 2006 to 2017 and the public procurement sales. As a result of analysis through the panel regression model, firms with a greater degree of public procurement showed a higher growth rate, and this relationship was stronger with younger firms. This result not only contributes to the existing academic discussion on the effectiveness of public procurement, but also has significance in the establishment of public procurement policy.

  • The behavior of oxygen precipitation was investigated in radial direction using Si wafers with different vacancy-related defects generation area. The behavior of oxygen precipitation in radial direction is strongly dependent on the size of vacancy rich area which is related with crystal growth condition. Oxygen precipitation rate is more enhanced in vacancy rich area than that of interstitial rich area. And anomalous oxygen precipitation is generated in the marginal bands of vacancy and interstial area. In V/I boundary, however, oxygen precipitation is suppressed to nearly perfect.

  • Recently, US, EU and major development countries, including Korea, have set green growth strategy the for national robust economic growth. Green growth strategy was also adopted as economic stimulus policy. Korea also have established some policies for green growth such as Green Growth National Strategy and 5-years Plan. Thought the SMEs play an important role as the innovative driver that can supply material and components for final products, there are few policies for joining green growth strategy. So, the purpose of this paper is to explore the current extent of public procurement for technology-development products and propose the betterment of it. Firstly, we analyzed the public procurement-policies of major countries to kinds of policy-purposes and types including Korea. and then we deducted the needs to policy utilizing the public procurement for joining the SMEs to green growth strategy. Second, we proposed that the objects of purchase conditional public procurement policy be extent to the pre-commercial technologies. The pre-commercial technologies could be performed further R&D by some other compaines or pubic institutes. Considering the natures of green technology-such as quasi-public-, this improvement would be helpful for SMEs which could create initial-marketplace and sales-references.

  • Currently, the role of public accelerators in the domestic accelerator market is gradually expanding. Accordingly, in order to establish relevant policies properly, it is necessary to check the effect and validity of public accelerators' investment. However, there is no quantitative research conducted on domestic accelerators, using their financial data, as domestic accelerators have a short history and quantitative data on them are not disclosed. Therefore, this study conducted an empirical analysis with financial data of the startups that received equity investments from public accelerators to confirm the effect of public accelerators'investment in startups. A regression analysis was conducted with financial data from 112 startups that acquired investments from public accelerators in the period of 2016~2020. And the findings are as follows: First, it was found that the initial investment of public accelerators had an effect on the growth and profitability of startups. Specifically, it was confirmed that the initial investment of public accelerators had a positive (+) effect on sales growth rates and total asset growth rates, which are growth indicators. Second, it was found that the joint investment of public accelerators had a significant positive (+) effect on profit margin, an indicator of profitability, rather than on growth. Therefore, it is deemed that it will be a great force for growth if investment in the early-stage startups that showed significant investment results in this study is continuously expanded in combination with support projects, which are a strength of public accelerators. Since this study has confirmed the investment effect of public accelerators, it is deemed necessary to actively promote policies that direct public accelerators' projects toward improving the performance of startups through joint investment with the private sector and supplementing private accelerators' deficiencies.

  • 공공기술을 활용한 스케일업(Scale-up)이 기업의 새로운 성장 전략으로 주목받고 있다. 스케일업의 사전적 의미는 '규모 확대'다. 기술, 제품, 서비스, 경영 등 기업의 외형과 내실이 크게 개선되거나 그에 상응하는 성과 창출의 뜻이 담겨있다. 기업가치 10억 달러($1 billion) 이상, 설립된 지 10년 이하로 통칭되는 유니콘(Unicorn) 기업의 등장이 스케일업에 대한 관심으로 옮겨 붙은 양상이다. 스케일업은 이러한 차원에서 고성장 기업을 통칭하는 말로 쓰인다. 국가별로 차이는 있지만 직원 수 10명 이상, 최근 3년간 매출이나 연평균 고용 성장률이 20% 이상인 기업을 스케일업으로 정의한다. 문제는 미국과 같은 선진기업 환경에서는 핵심 기술이나 신성장 동력 확보차원에서 다양한 기업인수합병(M&A)이 추진되거나 오픈 이노베이션(Open Innovation, 개방형 혁신) 방식의 기업간 기술협력이 활발히 일어나고 있지만 우리나라는 상대적으로 그러하지 못하다는데 있다. 결과적으로 국내 기업 환경과 사회적 분위기를 감안해 공공연구기관으로부터 기술을 이전받거나 연구개발특구진흥재단이 추진하는 연구소기업 제도를 활용한 스케일업의 중요성이 커지고 있다. 4차산업 시대를 맞아 기업간 합종연횡이 더욱 빈번하고 일어나고 기술간 융복합이 가속화되는 지금의 상황에 비춰볼 때 공공기술을 활용한 연구소기업들의 다양한 스케일업 사례는 우리에게 많은 시사점을 안겨준다. 기업성장을 위한 새로운 전략적 도구로 활용될 소지가 충분하다고 판단된다.

  • Investment in health through an array of public health policies will lead to improvement of health at all levels, and the improved health can reduce the socioeconomic costs incurred with diseases. And finally, with reduced healthcare costs associated with diseases and health problems, economy will be able to achieve economic growth and development. Using simultaneous equations model, this study aims to identify this possible channel from public health policies to economic growth. Specifically, the policy effect is investigated on a basis of main disease groups and aging groups. The public health policies are proved to reduce healthcare costs related with disease groups including respiratory, digestive, circulative, and infectious disease, and with all age groups except 20~39 group. And the reduced healthcare costs have shown to increase the real gross domestic products in those group above.
