최근 정부는 이러닝 콘텐츠 개발의 대가 기준에 대한 조사를 기반으로 명확한 대가 기준을 수립하고 이러닝 산업의 특성을 반영한 이러닝 콘텐츠 개발 대가 산정 가이드라인(기준)을 공개하였다. 그러나 제도적인 뒷받침이 없으면 제도가 취지와 목적을 달성하지 못하고 사문서화될 소지를 안고 있어 정책적 기반 마련이 필요하다 이에 본 연구는 대가기준 활용 활성화를 위해 이론적 배경 정리와 분석을 통해 대가기준의 단계적 적용 활성화, 대가기준의 제정 고시 및 정기적 조정, 대가기준운영위원회 운영, 이러닝산업 실태조사와의 연계성, 저작권 공동 소유 문화 확산, 개발과정의 체계적인 모니터링, 대가기준 적용 활성화 정책 연구, 표준계약서와 연동을 통한 정책 실효성 제고 등의 정책을 제언하게 되었다.

This paper empirically evaluates the effects of regional and industrial R&D on the performances of individual firms in two separated stages: (1) the stage of technological outcome from R&D and (2) the stage of economic outcome from technological outcome. Technological spillovers are separated from negative congestion effects through the stage-specific estimation. The firm-level Korean Innovation Survey data merit in coping with the endogeneity problem inherent in the estimation of spillovers. The estimation results show that: (1) there exist significant R&D spillovers both in regional and industrial dimensions, (2) the hypothesized technological spillovers and economic congestion effects are both in effect, and (3) firms with smaller individual R&D investments show greater spillovers.

Since the foreign currency crisis, Korean economy has suffered recession and the government launches residence and real estate policy in order to increase the demand and trade of real estate and to help the economy revitalization. 1 As a result, the rate of economy growth is shown the high increase with the figure of 10.9% in 1999 and 8.8% in 2000. However, it brings overheating market as a negative effect. Although, the government established the policy for the control of speculation, the policy causes instability of economy. This study is to analyze the effect between the residence policy and the housing cost since the foreign currency crisis through housing sale price estimation and housing lease price estimation and is to apply the basis data of the next residence policy.

In North-East Asia, Port traffic in Asia-North America sea route has been rapidly increasing due to economic growth in China and ASEAN. Furthermore, the major shipping companies directly call at northern chinese ports like Qingdao, Dalian and Tianjin without passing through Korean ports on Asia-North America sea route. To acquire a port traffic and develop a hub port, governments in North-East Asia have intensively invested in the development of port. Therefore, Busan new port and Gwangyang port have been developed in Korea. According to the medium-long term development planning, the port should give a enormous budget investment for the port facilities construction. So the inaccurate estimation may lead to the unreasonable port development policy. Firstly, based on the estimation of Chiang Bong-Gyu & Yang Hang Jin(2005), this study gave a comparison with the estimation of Ministry of Maritime Affairs and Fisheries(2001) and OSC/Glori(2005). Secondly, taking into account the influence factors for port traffic, this study made an estimation of port traffic for Busan new port. On the basis of this estimation, this study is compared with the estimation of Ministry of Maritime Affairs and Fisheries(2001) and OSC/Glori(2005). In conclusion, in case of the development of Busan new port, based on the estimation of Ministry of Maritime Affairs and Fisheries(2001), this study should the high possibility that the Busan new port will be serious lack of the port facilities in the year of 2011. And according to the OSC/Glori(2005)'s estimation result, there is a lack of the port facilities, though we have modified the port investment plan.

본 연구는 수간곡선식을 이용하여 아까시나무의 입목 수간재적표를 개발하고자 수행하였다. 이용한 수간곡선식은 Kozak 모형이었으며, 모형의 모수를 추정하였다. 추정한 모형은 통계적으로 적합성이 인정되었으며, 잔차분석 결과도 양호한 것으로 판정되었다. 따라서 본 모형이 아까시나무 수간재적표를 조제함에 있어 충분히 이용될 수 있을 것으로 사료된다. 그리고 수간재적표는 이용자의 편의를 위하여 수피 포함 및 수피제외 재적표를 조제하고자, 수피두께추정식을 개발하여 이용하였다. 수피두께추정식 역시 통계적으로 유의성이 인정되었다. 따라서, 본 모형이 아까시나무 수간재적표를 조제함에 있어 충분히 이용될 수 있을 것으로 사료된다. 또한, 국내에서 처음으로 개발한 아까시나무의 수간재적표는 임학뿐 만 아니라 타 분야에 널리 사용되기를 기대한다.

Decisions on reliability screening rules and burn-in policies are determined based on the estimated reliability. The variability in a semiconductor manufacturing process does not only causes quality problems but it also makes reliability estimation more complicated. This study investigates the nonuniformity characteristics of integrated circuit reliability according to defect density distribution within a wafer and between wafers then develops optimal burn-in policy based on the estimated reliability. New reliability estimation model based on yield information is developed using a spatial stochastic process. Spatial defect density variation is reflected in the reliability estimation, and the defect densities of each die location are considered as input variables of the burn-in optimization. Reliability screening and optimal burn-in policy subject to the burn-in cost minimization is examined, and numerical experiments are conducted.

본 연구 목적은 이러닝 콘텐츠 개발 대가 산정 가이드라인 활용 활성화 정책의 근거를 제시하는 것이다. 이를 위해 이러닝 콘텐츠 개발 대가 산정 가이드라인(대가기준과 혼용)의 실효성에 대한 산업계 임직원들에 대한 설문 등을 통해 조사하고 이를 통계적으로 분석하였다. 분석 결과, 콘텐츠 사업 수주후 손실을 본 경험 기업과 수주를 포기한 경험 기업 등이 대가기준의 실효성에 대해 상대적으로 부정적인 인식을 가지고 있다. 그런가 하면 콘텐츠 전문기업은 대가기준의 실효성에 대해 상대적으로 긍정적인 인식을 가지고 있다. 결론적으로, 본 연구는 이러닝 콘텐츠 개발대가 산정기준(가이드라인)이 권고, 제정 고시를 넘어 수발주 현장에 정착되고 나아가 이러닝 산업 발전에 큰 기여토록 하는 제도적 장치를 정부가 가능한 한 빨리 마련할 것을 권고하였다.

This paper investigates the impact of monetary policy independence shock on bond yield by allowing for heterogeneous coefficients in the model based on panel data for 19 developing countries using quarterly data from 1991 to 2016. First, we estimate the model using conventional panel VAR estimation with the assumption of homogeneous coefficients across countries. Second, by performing Chow and Roy-Zellner tests to check the homogeneity assumption, we find that the assumption does not hold in the model. Third, we apply a mean-group estimation for panel VAR as a solution for heterogeneity panel model. The results reveal that central bank independence is effective in reducing bond yield with the maximum at period 6 after the shock. Shock one standard deviation bond yield has a negative effect on consumption and investment. We determine that central bank independence has a contradictory effect on real activity; a negative effect on consumption but a positive influence on investment for the first two years after the shock. Additionally, we split our sample into three groups to make the subgroups pool. Our empirical result shows that monetary policy independence shock reduces bond yield. Meanwhile, the response of economic activity to bond yield varies for all three groups.

To clarify the relationship between the medical supply(medical persons and goods) and the use of bed, the author has made comparison among OECD 24 countries. Per Capita Bed-days can be divided into Average Length of Stay and Admission Rate, and these three variables were regressed upon both In-patient Care Beds of all medical institutions including acute somatic, psychiatric, special, nursing homes and other long-term care and Share of Total Health Employment in Total Employment. The result of regression analysis shows a statistically significant positive relationship between In-patient Care Beds and Average Length of Stay, and negative relationship between Share of Total Health Employment and Admission Rate. In addition to Ordinary Least Square(OLS) estimation, amended Bounded Influence Estimation(BIE) was also made to adjust the influence of outliers. Japan shows a very large number of In-patient Care Beds and a very low Share of Total Health Employment, and this medical situation is judged to have close relation to her long Average Length of Stay and low Admission Rate.

This paper develops a recursive multinomial probit model and describes its estimation method. The recursive multinomial probit model is an extension of a recursive bivariate probit model. The main difference between the two models is that a single decision among two or more alternatives can be considered in each choice equation in the proposed model. The recursive multinomial probit model is developed based on a standard framework of the multinomial probit model and a Bayesian approach with a Gibbs sampling is adopted for the estimation. The simulation exercise with artificial data sets is showed that the model performed well. Since the recursive multinomial probit model can be applied to analyze the causal relationship between discrete dependent variables with more than two outcomes, the model can play an important role in extending the methodology of the causal relationship analysis in innovation research.
