국가차원의 창업장려책으로 인해 제2의 벤처붐이라고 부를 만큼 스타트업 및 벤처 창업이 활성화되면서, 데스밸리를 극복하고 창업의 성공률을 높이기 위한 노력의 중요성이 대두되고 있다. 기업이 생존율을 높이고 성장으로 나아가기 위해서는 죽음의 계곡에 직면하는 가장 큰 부분인 자금 조달 및 투자유치에 대한 고민과 대책이 필요하다. 창업의 활성화는 창업초기의 높은 실패율을 낮출 수 있는지의 여부가 그 성패를 좌우하는 중요한 요인이다. 기업의 생존은 기업의 내적 요인뿐만 아니라 기업의 외적요인인 시장이나 산업의 상황에 의해서 영향을 받는다. 본 연구에서는 혁신 부서를 보유한 기업의 전략적 지향성과 외부지식활용 능력인 흡수역량이 스타트업의 데스밸리 극복에 미치는 영향을 살펴보고자 한다. 또한 스타트업 생태계 특징인 개방형혁신과 벤처캐피탈 지원의 조절효과를 분석하고자 한다. 종속변수는 기업이 손익분기점을 달성 한 후의 매출액, 순이익, 시장점유율, 종업원 수의 증가를 봄으로써 데스밸리 극복의 기준으로 삼고자 한다. 분석결과 전략적 지향성은 데스밸리 극복에 정(+)의 영향을 주는 것을 밝혀졌다. 흡수역량과 개방형혁신, 벤처캐피탈의 지원의 조절효과는 표본수가 적고 결측값 있으므로 유의미한 영향을 확인하지 못하였지만 추후 표본수를 늘려 다시 측정한 후 그 결과를 보고자 한다.

As the fashion industry comes under the influence of globalization throughout all fields of industry, the globalization and the market entry strategies are required for Korean fashion firms. This study attempted to analyze the factors influencing foreign entry mode of Korean fashion business based on Eclectic Theory. Data collection has been carried out from November 25 until December 25, 2005. The questionnaires were sent through e-mail or fax to 622 trading companies. 67 questionnaires were returned for a response rate of 10.7%. Of these returns, 61 usable questionnaires were employed for data analyses. Descriptive analysis, factor analysis, discriminant analysis, and t-test were used for data analysis. First, the most important venture motivation was price competitiveness and many firms were engaged in both production and sales in their target countries, which were mainly in Southeast Asia. Second, the firm's ability and experience were found out as ownership advantage factor, investment stability and market potential as location advantage factor, and contract stability as internalization advantage factor. Third, the result of discriminant analysis showed that location advantage factor was a significant factor in predicting the entry of fashion firms into foreign countries.

To assess the total cost with all stages of facilities, the feasibility of Life Cycle Cost (LCC) analysis was examined in this study to estimate the livestock manure treatment system and optimal decision making process. For the economic evaluation, the plant/equipment investment and annual operation cost of four Public Livestock Recycling Facilities, whose treatment capacity is 100 ton piggery manure per day, was compared. The initial cost was in the range of 2,699 million won to 3,202 million won, where T and E methods were highest and lowest, respectively. The annual operation cost was in the level of 378 million to 498 million won, which decreased in the following order : T method > J method > E method > B method. For the LCC analysis, 4.7% of interest rate, 3.13% of inflation rate, and 1.52% of net discount rate was considered by the data received from Bank of Korea and Statics Korea in the period of 2000 to 2009. Also, for the calculation of present value factor, the durable years of civil engineering & construction, machinery and electric instrument was 30 years, 10 years and 15 years, respectively. Based on these consideration, operation cost was in the range of 17,570 won/ton to 20,661 won/ton, and E method (17,570 won/ton) was economical and B method (20,661 won/ton) was non-economical. Though initial cost of T method was higher than that of B method, LCC analysis of T method was lower than that of T method due to the lower operation cost. Therefore, LCC analysis, which considers both initial cost and operation cost, is more reasonable evaluation method than either initial cost or annual operation cost. For the change of LCC analysis according to the uncertainty, the sensitivity analysis was carried out using fluctuation magnitude of discount rate in the period of 2000 to 2009. As a result, LCC analysis evaluated by discount rate was stable for the uncertain factors since the cost leadership did not change even though the sensitivity analysis varied. In summary, the economic evaluation using LCC analysis could be an efficient reference to choose the suitable livestock manure treatment plants. Furthermore, standardization of statement calculation for the actual cost analysis should be conducted and more detailed study is necessary to validate this summary. Therefore, the application of comprehensive technology evaluation, which considers LCC analysis, should contribute in obtaining objectivity and enhancing reliability for the 'Evaluation of Livestock Manure Treatment System and its Technology'.

For the application of the diffusion equation, slope height and maximum slope angle are calculated from the plotted slope profile. Using denudation rate as a solution for the diffusion equation, an apparent age index can be calculated, which is the total amount of denudation through total time. Plots of slope angle versus slope height and apparent age index versus slope height are useful for determining relative or absolute ages and denudation rates. Mathematical simulation plots of slope angle versus slope height can generate equal denudation-rate lines for a given age. Mathematical simulations of slope angle versus age for a given slope height, for equal denudation-rate at a particular profile site, and for comparing to other sites having controlled ages.

Amorphous $Fe_{68.5}Co_5M_3Cu_1Si_{13.5}B_9(M=Nb, Mo, Mn, Cr)$ alloys were prepared by using rapidly quenching techinque and were annealed above their crystallization temperatures. Coercive force, initial permeability and AC power loss of the annealed $Fe_{68.5}Co_5M_3Cu_1Si_{13.5}B_9(M=Nb, Mo, Mn, Cr)$ alloys have been studied systematically. Nanocrystallines are formed in the annealed alloys which include Mo and Nb. Remarkably improved soft magnetic properties are obtained in the alloys whose average grain size is around 10 nm. However, soft magnetic properties of the alloys are degraded when grain size is less than IOnm or larger than 15nm. It is considered that the degradation of soft magnetic properties in the alloys whose average grain size is less than 10 nm is due to the Fe-rich amorphous phase retained at grain boundary during the initial crystallization process.

최근 정부가 저탄소 녹색성장을 새로운 국정비전으로 제시하고 혁신적 그린에너지 기술개발을 위해 연평균 20%이상의 R&D 예산을 증액하고 있는 상황에서 연구개발결과의 상용화율 제고를 위한 연구기획, 평가, 관리시스템의 개선이 시급한 실정이다. 특히 선진국의 경우 최근 3년간 에너지분야 R&D의 상용화율이 미국 35.9%, 유럽 46.8%로서 24.2%인 한국에 비해 매우 높다고 할 수 있다. 이와같은 격차가 존재하는 것에 대해서 다양한 요인을 생각해볼 수 있겠지만, 크게 시장적인 또는 산업적인 측면에서의 중요도를 기준으로 연구과제를 선정하지 못하고 있다는 점과 연구개발결과를 효율적으로 사업화하고 있지 못하고 있다는 점을 생각해볼 수 있다. 특히 에너지 분야는 대규모 자금의 초기소요 및 개발기술 상용화기간의 장기화등으로 인해 사업화 실적이 타산업대비 매우 저조한 편이다. 이와같은 연구결과의 사업화와 관련된 문제점을 극복하기 위한 노력으로 국내에서 다양한 형태의 기술사업화 지원프로그램이 운영괴고 있으나, 에너지 분야에 특화된 프로그램은 부족한 상황이다. 반면에 미국의 경우, 재생에너지 R&D분야 전문투자자 그룹인 클린테크그룹 등을 중심으로 2002년부터 현재까지 다수의 녹색기술분야에 특화된 기술사업화 지원 프로그램을 운영하고 있다. 그 결과 현재까지 약 9년간 총 16억$의 투자유치에 성공함으로써 민간투자 활성화 역할을 담당하고 있다. 따라서 국내의 경우에도 이와같은 에너지 R&D 결과를 효과적으로 사업화로 연계시킬 수 있는 관련 프로그램 등이 시급히 도입되어야 할 것이다. 본 논문에서는 국내의 사업화 부진문제를 해결하기 위한 하나의 방안으로서 올해부터 정부주관으로 시행되고 있는 녹색인증사업을 활용하여 사업화가 유망한 기술 및 기업을 선별하고, 이에 대해 사업화 지원을 위한 후속프로그램을 적극 지원함으로써 연구개발결과의 경제적 활용도를 획기적으로 개선하는 방안을 제시하고자 한다. 또한 사업화 지원프로그램의 효율성을 높이기 위해 수도권, 영남권, 호남권 등 지역별 TP 등을 중심으로 기술사업화 협력 네트워크를 구축하고, 이를 기반으로 한 수요기술조사, 기술마케팅, 투자자유치 등의 관련프로그램을 개발하여 전단의 시스템과 융합시킴으로써 향후의 정부주도 R&D결과의 상용화율을 제고할 수 있는 시스템을 제안하고자 한다. 이에는 에너지 R&D분야별 기술적 시장적 특징분석, 지역별 산업특성과 기술공급 서플라이 체인분석을 토대로 한 기술이전 잠재수요기업 투자자를 대상으로 한 맞춤형 기술사업화 프로그램 등이 포함된다. 마지막으로 제안된 시스템에 대한 타당성 검증을 위해 올해년도에 시행한 녹색인증 기술사업화 연계프로그램 및 기술사업화 협력네트워크 활용사례 등을 분석하고, 향후 발전방향으로서 기술사업화 유관기관간간 기술사업화 정보교환 및 사업화 유망기술 기업 마케팅 등을 기본내용으로 한 시장지향적 녹색에너지 R&D 관리 시스템 구축방안을 제시하고자 한다.

During few decades, Korean economy has been growing with heavy and manufacturing industries. However, the economy meets limitations of growth rate, and employment rate. The Korean government has been trying to overcome these limitations using development of venture businesses and re-organization of industrial ecosystem. These efforts make high survival rate of recent venture companies. There are previous researches about relation between characteristics of entrepreneur and managerial performance, there are several limitations. Firstly, most of papers were based on survey with specific region or industry. Secondly, related researches were carried out with unable to distinguish among firm's survival periods. This paper uses the '2017 Survey of Korea Venture Firms' data that is approved by the Korean government. This data includes whole industries and survival periods. The aim of this research is finding the effect of characteristics of entrepreneur on managerial performance of venture firms by different survival periods using data envelopment analysis (DEA). If entrepreneur has doctoral degree, the firm's managerial performance is lower than bachelor degree. In addition, over 10 years of working career, and joint-venture have positive effect on firm's performance. This paper can provide valuable information to venture related policy makers and investment decision makers.

The major goal of this paper falls on developing new rational valuation model, to help companies and investors in the early stage of growth as to preparing and negotiating valuation of investment, by applying new reasonable discount indexes of calculating Discount Cash Flow in valuation of the start-up which has been recognized the critical fatal flaws of DCF with them. There are three specific studies done in this paper. First, this paper found the solid and viable bases of rational discount indexes as to applying DCF in valuing companies in the early growth stage with reviewing the previous studies including Berkus method, Scorecard Method, and Risk factor Summation method classified the most effective tools of valuing pre-revenue generating companies. Second, this paper quoted and analyzed the previous models and studies, so called, 'DCF-Prime' of applying DCF method as to value companies in the early growth stage by taking all risk factors innate to the companies in the early growth stage as the discount rate Beta coefficient. Third, this paper propose more viable and solid valuation models, so called, 'DCF-Plus'of combing all validated valuation factors in Berkus, Scorecard, and Risk Factor Summation methods into applying separate discount bracket after DCF Valuation over the companies in the early growth stage instead of taking them as the factors of discount rate, beta coefficient, like the previous model of DCF-Prime. DCF-Plus mainly developed in this paper will not only provide more rational valuation bases as to investment negotiation between companies and investors in the early growth stage, but also providing more accountable guidelines to companies in the early growth as to prepare investment raising and accelerating their company's value by themselves.

In this study, we have constructed a measuring system to investigate tensile stress of tendons, which is employed in bridges, by means of the magnetic non-destructive testing (NDT) method. For the twisted 7-strands tendon, we have used Wiedemann effect. An ac current was applied to the tendon and voltage induced from Search Coil on Tendon (SCT) under applying tensile stress was measured. The measuring system consists of tensile stress applying apparatus up to 2 GPa, and ac current supply to apply current to the tendon directly to magnetize the tendon. We have invested two kinds of tendon which were produced by different companies for testing with constructed measuring system. Voltage induced from SCT was decreased up to 1.5 GPa linearly and two kinds of tendon which were produced by different companies shows similar trends. Thus, Wiedemann effect was also applicable to measure tensile stress of tendon by means of magnetic NDT.
