산업재해 방지를 위한 New Austria Tunnel Method 수지에서 빔산란에 의한 Monte Carlo 시뮬레이션에 관한 연구
남상성 ( Sang Sung Nam ),이주엽 ( Joo Youb Lee ) 한국유화학회 2013 한국응용과학기술학회지 Vol.30 No.3
The influences of scatterer and absorber in turbid material by light scattering on silica fume of additive were interpreted for the scattered intensity and wavelength. The molecular properties have been studied by Monte Carlo simulation in resin of New Austria Tunnel Method. It has been found that the effects of optical properties in scattering media could be investigated by the optical parameters(μs, μa ,μt). Monte Carlo Simulation method for modelling of light transport in the civil engineering and construction field was applied. The results using a phantom were discussed that the distance from source to detector is closer, and scattering intensity is stronger with those obtained through Monte Carlo Simulation. It may also aid in designing the best model for coatings and corrosion for the durability of metal constructions.

원자력에 대한 의존도가 큰 프랑스는 기후변화 시대에 들어와서 유럽연합의 방침에 따라 재생에너지로의 에너지전환을 도모하게 되었다. 온실가스의 감축과 에너지 안정을 목표로 한 장기적인 프로그램법을 2005년에 제정한 후 지속적이고 단계적으로 추진해온 새로운 에너지정책은 2009년 그르넬-1법에서 기본계획을 잡고, 2010년 그르넬-2법에서 실행계획을 수립하면서 본격화되었다. 이두 법은 모두 재생에너지 개발과 사용을 지원하는 내용을 담고 있다. 교통과 주거 등 도시계획을 출발점으로 하여 에너지생산의 지원, 의무구매를 이용한 사용의 장려, 공급망 확대 등이 그 주요 내용이다. 이러한 흐름에서 2012년 대선으로 집권한 사회당정부는 녹색성장을 위한 에너지 전환법을 입안하여 드디어2015년에 공포되었다. 이 법은 건물의 개축과 무공해 교통 및 순환경제를 통한에너지 절약, 재생에너지 개발 및 이를 위한 재정·행정상 수반조치를 주된 내용으로 하고 있다. 2030년까지 온실가스 배출을 40% 감축하고 재생에너지 비중을 최종 소비량의 32%까지 끌어올리고, 2050년에는 절반을 차지하게 하는 것이 이 법이 규정하고 있는 ``에너지전환의 목표``이다. 이제 친환경 에너지 사용 비중 확대로 에너지정책을 확실하게 전환한 프랑스의 사례는 포괄적 접근법, 국민과의 소통 등 우리에게 좋은 정책적 시사점을 주고 있다. La France dependant a l``energie nucleaire, a l``ere de changement climatique, a planifie la transition energetique vers les energies renouvelables, conformement aux politiques de l``Union europeenne. Apres Une loi de programme a long terme pour stabiliser les objectifs de reduction des gaza effet de serreet de l``energie en 2005, les nouvelles politiques d``energie poursuivies progressivement ont ete concretisees en tenant un plan de maitrise dans la Loi Grenelle-Ⅰ de 2009 et en etablissant un plan d``action dqns la Loi Grenelle-Ⅱ de 2010. Ces deux lois contiennent les aides le developpement et l``utilisation des energies renouvelables. L``urbanismeen en tant que point de depart, Soutien a la production d``energie en encourageant l``utilisation par l``achat obligatoire, l``elargissement du reseaux d``approvisionnement sont les contenus principals. Dans cette tendance, le gouvernement socialiste au pouvoir en 2012 a elabore le projet de loi relatif a la transition energetique pour la croissance verte a finalement promulgue en 2015. Cette loi comprend les economies d``energies par biais de la renovation des batiments, du transport propre et de l``economie circulaire, le developpement des energies renouvelables et les mesures d``accompagnement financier et administratif.La reduction de 40% des emissions de gaz a effet de serre d``ici au 2030 et l``augmentation de la part des energies renouvelables a 32% et a moitie 2050 de la consommation finale sont les buts de transition energetique, prevus dqns la loi. Maintenant,surementle Le cas de la France qui a about it la transition de la politique d``energie vers la consommation d``energie verte nous donne une bonne implications politiques comme l``approche globale, la communication avec le public.
비금속 자원 재활용을 위한 전해부상 장치를 이용한 고농도 유기질 폐수의 재활용에 관한 연구
김기준 ( Ki Jun Kim ),남상성 ( Sang Sung Nam ) 한국유화학회 2012 한국응용과학기술학회지 Vol.29 No.4
고농도 유기질 폐수처리를 위해 전기화학적 방법의 사용에 있어 관심이 고조되고 있다. 전기화학적 방법의 기술은 음식물폐수 및 공업적 폐수 문제를 해결하는데 이상적 처리 방법이다. 다른 화학적 처리 방법과는 다르게 전기화학적 처리장치는 2차 폐수의 부피를 증가시키지 않고 용수와 유기질 비료로 재활용한다. 전기화학적 방법은 전해부상장치를 무기화학적 약품과 병행하여 더욱 효과적으로 음식물 폐수를 처리한다. 이 연구는 2차 처리로 초음파와 오존처리로 탈색, COD와 BOD가 격감함으로 용수 및 유기질 비료로 활용하도록 실험하였다. There is an increasing interest in the use of electrochemical methods for the food waste treatment. The technologies using the electrochemical method provide ideal tools for approaching industrial and food wastes problems. Unlike other chemical treatments, the electrochemical systems do not make the volume of the secondary waste increase. The electrochemical methods can be operated with electrochemical apparatus and inorganic agent allow selective separation and recovery and even quieter than others. This study concerns design factors, electrode construction and wastewater treatment process of the electrochemical apparatus. The experiment of color, COD and BOD removal is much effective in using electrochemical method with ultrasonication and ozonation.

With interest in and importance of the technology transfer and commercialization increasing globally, this study identified and prioritized the factors that should be considered when facilitating technology transfer and commercialization through the importance analysis using AHP. As a result, this study found that system and organization that can efficiently facilitate technology transfer were given relatively greater importance and recognition. Followed by, TLO with securing the independence and professionalism was analyzed as relatively higher importance among the secondary class factors. Meanwhile, financial support for technology transfer and commercialization was not given enough attention. This seems to reflect the reality that quantitative performance has been the focus of interest and there was not enough understanding attained as to the importance of creating economic value through start-up or commercialization. This study suggests that there should be a system for systematic management and evaluation of target technologies, the technology licensing office(TLO) should be given a clear role (to operate as an independent organization with professional skills and knowledge, etc) and financial support should be provided so that good performance can be achieved out of technology transfer and commercialization.

A global trend has seen a rise in national R&D spending. South Korea`s gross R&D investment is ranked sixth in the world, and highest in the world in relation to GDP standing at 4.29% in 2014. In line with the continued expansion of R&D investment, national science and technology capabilities have been enhanced both quantitatively and qualitatively. However, despite R&D budgetary increases and selective utilization of outcomes, a significant number of outcomes have not been linked to commercialization and remain in a dormant state. This study aims to determine factors that lead R&D outcomes to technology commercialization by examining prior research. Analysis of quantitative data was performed using a structural equation. Results of this study are expected to be used as policy materials that can help guide existing government`s initiatives which emphasize funding technology suited to marketability.

In accordance with the continued expansion of domestic R&D investment, economic analysis of this enormous R&D investment is inevitably required. However, there is no official price deflator from the nominal R&D expenditures to the real expenditures. In this background, this study is to discuss the calculation method and the process of calculating the R&D deflator. We observed the values between the R&D deflators derived in accordance with the calculation method are compared each other, and the degree of discrepancy between nominal R&D expenditures and real expenditures through calculation of R&D deflator. The significance of this study is to provide a new calculation method for R&D deflator that is used in technological innovation for the establishment of S&T policies or in empirical research for the related R&D. In the future, some limitations such as representative problem of proxy indicators should be supplemented in order to derive a more appropriate deflator.
