가상수의 흐름을 보다 가시적으로 파악하기 위하여 대두된 개념이 물발자국(water footprint)이다. 이는 흔히 사용되고 있는 생태발자국(ecological footprint)이나 탄소발자국(carbon footprint)에 착안하여 도입된 개념으로 한 국가의 물발자국은 직 간접적으로 물건이나 재화를 생산하는데 국민이 소비하는 물의 총량으로 정의된다. 물발자국을 내적/외적으로 단순히 구분하여 산정하는 방식이 진화하여 1단위의 생산에서 유통 및 서비스까지 확대하여 그 전 과정을 모두 포함하는 물발자국 산정방식이 도입된 것은 최근의 일이다. 직접적인 물사용과 간접적인 물사용을 구분하여 물발자국을 산정하고, 그 위에 물의 성질에 따라 green water, blue water, 그리고 grey water로 각각 개념을 상세화하여 물발자국을 산정하는 방안이 도입되었다. 2009년 물발자국 산정의 표준화를 위한 스위스의 제안이 ISO에 제출되었고, 각 국가들에 의한 투표가 진행되어 2010년 물발자국 국제표준안이 채택되었다. 본 연구는 이러한 국제기구에 의한 일련의 국제표준화 작업을 대상으로 진행되었다. 2014년 ISO/TC 207 국제총회가 개최되어 환경경영시스템(SC1), 환경감사(SC2), 환경 라벨링(SC3), 환경성과평가(SC4), 전과정평가(SC5), 온실가스관리(SC7)의 6개 분과위원회(Sub-Committees)가 구성되어 세부논의가 진행되었으며, 이러한 과정을 분석함으로서 물발자국 국제표준(ISO 14046)과 향후 우리나라의 대응방안을 고찰하였다. 물발자국 국제표준(ISO 14046) 제정을 통해 물발자국의 필요성 및 중요성에 대한 국가 간 합의는 도출되었으나, 적용시기 및 세부적인 방법론 등에 대한 이견이 여전히 존재하고 있다. ISO 14046의 실질적 적용에 필요한 세부사항과 관련된 기술보고서 작업초안(WD 14073)은 작업반(SC5/WG8)에서 진행되고 있다. 그러나 물발자국 국제표준이 국가 간 무역장벽이나 특정국의 진입을 막는 수단으로 사용될 수 있는 점 등 실질적으로 국제표준의 도입에 따른 문제점 역시 존재한다. 본 연구에서 제시된 국제표준의 도입 방안을 통하여 가상수무역의 국제적 선점효과를 기대함과 동시에 수자원의 유효한 활용을 기대할 수 있을 것이다.

The ground sample distance of KOMPSAT-3 is 0.7 m for panchromatic band, 2.8 m for multi-spectral band, and the swath width of KOMPSAT-3 is 16 km. Therefore, an image of an area wider than the swath width (16 km) cannot be acquired with a single scanning. Thus, after scanning multiple areas in units of swath width, the acquired images should be made into one image. At this time, the necessary algorithm is called image mosaicking or image stitching, and is used for cartography. Mosaic algorithm generally consists of the following 4 steps: (1) Feature extraction and matching, (2) Radiometric balancing, (3) Seamline estimation, and (4) Image blending. In this paper, we have studied an effective seamline estimation method for satellite images. As a result, we can estimate the seamline more accurately than the existing method, and the heterogeneity of the mosaiced images was minimized.

This study aims to explore the development of FinTech industry in Korea by comparing and analyzing the effect of job creation in the FinTech industry in Korea and the US. The industry Input-Output table used in the analysis used WIOD, which is composed of the same industrial classification and monetary unit in both Korea and the US. For the analysis, the FinTech industry is composed of ICT sector and financial sector as one industry. This study also compares the employment creation effect in the ICT sector and the financial sector, in addition to the FinTech industry, in order to distinguish the FinTech industry characteristics of the two countries. As a result of the analysis, when the investment or production of 1 million US dollars was made in the FinTech industry in Korea, the employment inducement effect was 11.33 and the employment inducement effect was 9.47, indicating a total employment creation effect of 20.8 persons. In the United States, the Direct employment effect was 8.07 and the indirect employment effect was 7.72, indicating that the employment creation effect was 15.79. However, as a result of classification by the average employment creation effect of the national economy, Korea 's FinTech industry is classified as indirect employment advantage with a high indirect employment inducement effect and the United States is classified as an employment creation advantage with high both direct and indirect employment inducement effect.

The objective of this study was to estimate genetic parameters for test-day milk production and somatic cell score using field data collected by dairy herd improvement program in Korea. Random regression animal models were applied to estimate genetic variances for milk production and somatic cell score. Heritabilities for milk yields, fat percentage, protein percentage, solid-not-fat percentage, and somatic cell score from test day records of 5,796 first lactation Holstein cows were estimated by REML algorithm in single trait random regression test-day animal models. For these analyses, Legendre polynomial covariate function was applied to model the fixed effect of age-season, the additive genetic effect and the permanent environment effect as random. Homogeneous residual variance was assumed to be equal throughout lactation. Heritabilities as a function of time were calculated from the estimated curve parameters from univariate analyses. Heritability estimates for milk yields were in range of 0.13 to 0.29 throughout first lactation. Heritability estimates for fat percentage, protein percentage and solid-not-fat percentage were within 0.09 to 0.11, 0.12 to 0.19 and 0.17 to 0.23, respectively. For somatic cell score, heritabilities were within 0.02 to 0.04. Heritabilities for milk productions and somatic cell score were fluctuated by days in milk with comparing 305d milk production.

디지털 전환은 기존 산업의 진입장벽 파괴에 따른 새로운 비즈니스 기회 확대, 자산의 디지털화에 따른 초기창업비용의 축소 등 창업 및 기업가적 활동 측면에서 중대한 환경적 변화를 초래하고 있다. 이러한 변화로 인해 기존의 기업가정신 이론으로 기업가들이 새로운 비즈니스 기회를 인식하고 기업가적 가치를 추구하는 일련의 과정을 이해하기에는 충분치 않으며, 기업가정신의 특성 및 효과에 대한 새로운 접근이 필요하다는 문제의식을 바탕으로 최근 디지털 경제 환경에서의 기업가정신을 조망하는 새로운 이론적 틀로서 '디지털 기업가정신'이라는 개념 및 관련 연구분야가 부상하고 있다. 본 연구에서는 국가 단위에서 디지털 기업가정신의 고용효과를 탐색적으로 파악하기 위하여 국제 기업가정신 관련 조사인 「글로벌 기업가정신 모니터(GEM)」 데이터를 활용한 상관 관계 분석을 실시하였다. 연구 결과, 기업가적 활동에 있어서의 디지털 기술 활용 의지, 창업 의지, 6인 이상의 고용창출 의지 등이 상호 간 긍정적인 관련성을 가지는 것으로 나타났다. 이는 디지털 기술에 기반한 창업 또는 기업가적 활동에 대한 의지가 일자리 창출과 긍정적인 관계를 가진다는 의미다. 해외 학자들을 중심으로 이루어지고 있는 디지털 기업가정신 연구는 기업가정신 및 창업 프로세스에 대한 디지털화의 영향이나 디지털 기술의 혁신 및 새로운 벤처의 탄생에 의해 창출된 기업가적 기회에 대한 논의가 주를 이루고 있는 데 반하여, 본 연구에서는 디지털 기업가정신에 의해 창출되는 성과에 대해 살펴본다는 점에서 차별성이 있다. 또한 국내에서 많이 다루지 않은 디지털 기업가정신 관련 연구를 수행하고 그 결과를 발표함으로써 동 분야에 대한 국내 학계의 관심을 촉진할 것으로 기대된다는 점에서도 학술적 의의가 있다.

Drug Development is very important for promoting public health and pharmaceutical industry. There has been many studies on the efficiency of drug development, but there are few studies on the drug development R&D performed by government. Since CCR model assumes unidirectional influence of input and output, it is not appropriate to analyze the efficiency of R&D due to the time-lag and spill-over effect. Also, BBC model which assumes variable returns to scale has difficulty in deriving priorities between decision making units. Recently, Range Adjusted Measure (RAM) model has been suggested in R&D efficiency analysis. RAM model measures the efficincy by eliminating inefficiencies under variable returns to scale assumption, and its strong monotonicity enables to provide clear priorities between decision making units. In this study, we analyzed the efficiency of national R&D programs for drug development using the two-step approach, including RAM model and Tobit regression analysis, and discussed major policy implications.

A linkage of emissions trading schemes among Korea, China and Japan demonstrates overall increase in gross domestic product (GDP). However, it also demonstrates reductions in household consumption, and the impact of integration could be very unbalanced between the countries. In particular, the reductions in domestic marginal costs are high in both Korea and Japan. Therefore, household consumptions in the two countries decrease despite increases in GDP because Korea and Japan will be purchasers of emissions rights. China, on the other hand, will experience the opposite. The unbalanced impacts on real household consumptions are intensified when emission credits are allocated via paid auctions instead of free allocation. This was demonstrated to be the case because the circumstances of three countries are intensified when using a paid emissions credit allocation scheme, and their differences could potentially hinder the cooperation between the three countries. Under the free allocation scheme, the emission trading schemes' unbalanced impacts on consumption could be mitigated, but unavoidable negative impacts of free allocation schemes are also serious. Based on the analysis results, Korea, China, and Japan will individually face complicated impacts if their carbon markets are integrated. Although the GDP of three countries will increase as a result of carbon market integration, the benefits of integration will surely be unbalanced, and the three countries will experience negative impacts in terms of actual consumption or employment. In particular, increases in income and consumption, reductions in employment, and energy dependence by credit purchasers (Japan and Korea) and production reduction and possibility of offshoring faced by revenue producing countries (China) could serve as a barrier to carbon market integration. To maximize the positive influences of carbon market integration while reducing the risks of negative side effects, the development and application of complimentary policy tools, such as import duties or discounts for emissions credits, are required.

This paper studies how the free trade agreements (FTAs) have changed the dynamics of Korea's imports since 1996. Specifically, the dynamic regression analysis on the transition of trade liberalization discovers three main findings: (1) import values of Korea increase gradually as FTAs enter into force; (2) the extensive margins of import work as a major source of the trade effect in the transition episode of FTAs; (3) the extensive margins of import tend to increase even before FTAs enter into force. This noble forward-looking effect suggests some potential foreign exporters or exporting goods enter the Korean market, especially when FTAs negotiation starts. It supports the early entry behavior of potential exporters found in recent international trade literature.
