In this study, the characterization of projects and analysis of R&D products and commercialization performances were done to serve some implications on the policy decisions related to the commercialization of R&D in marine and fisheries sector. A total of 212 R&D projects with 144 ones for marine and 68 for fisheries performed for 5 years, from 2010 to 2014, were sorted and analyzed on the respect of government budget, main performing body, and research period. The R&D result and commercialization performance were substituted to quantitative indicators, such as the number of published papers, the number of patents, the amount of the technology royalty, the number of technology transfers, and the improvement of public service, which were subjects to be analysed. Based on the results, this study suggests the policy implications for the success of national R&D program; 1) diversifying the main performing body, 2) operating the system for sharing research infrastructures among researchers, 3) introducing the adaptable R&D program management, 4) expending the portion of grants without detailed requests for proposal, and 5) leaning the investigation of R&D budgets on projects focusing on the practicalization and commercialization.

본 연구에서는 일본 문부과학성 과제인 혁신(革新, KAKUSHIN)과제를 통해 제공되는 고해상도(20km, 1시간) 기후모형(MRI-AM20km) 출력치를 이용하여 기후변화로 인한 가뭄 발생 특성을 변화를 살펴보았다. 가뭄 특성의 정량화를 위해 표준강수지수를 적용하였으며 일본에서 기록된 주요 가뭄 사상(1980~2001)에 대해 지상 관측 자료 (AMeDAS)를 이용하여 SPI를 산정하고 그 적용성을 파악하였다. 극한가뭄의 거동특성을 파악하기 위해 SPI가 -1.0 이하인 경우를 유효가뭄, -2.0 이하인 경우를 극한가뭄으로 분류하고 가뭄의 강도 및 빈도, 계절적 발생 특성을 파악하였다. 그 결과 대부분의 다른 기후모형과 마찬가지로 MRI-AM20km도 연강수량에 있어서 아시아 몬순 지역 대부분의 국가에서 증가할 것으로 예상하고 있지만, 특히 극한 가뭄의 경우 그 강도 및 빈도가 유의하게 증가할 수 있다는 가능성이 있음을 예상하고 있다. 또한 국가별 가뭄심도-영향면적의 관계를 살펴본 결과 대부분의 아시아 몬순 지역에 대해서 동일한 영향 면적에 대한 가뭄의 강도가 증가하고 지속기간이 증가할수록 그 경향은 더욱 뚜렷하게 나타나는 것을 확인할 수 있었다. 향후 가뭄특성을 지역화하고 대상 지역을 전 세계로 확장하여 가뭄 특성을 정량화할 필요가 있으며, 다양한 모형 출력치를 이용한 결과를 통해 결과의 타당성을 확인할 필요가 있다.

This paper discusses how the strategies for crime prevention are interrelated to sustainable urban development. The sustainable urban development for healthy and safe cities implies regulations or legal, lawful control to reduce fear of crime and prevent substantial threats to health and safety of individual persons as well as of the community. City planners attempt to apply to the strategies for crime prevention their perception of what the sustainable urban development should be with respect to urban environment. Many planners have studied on the possibility of reduction in fear of crime and actual crimes through environmental improvement. The results of their preliminary studies provide specific suggestions to reduce crimes and fear of crime by application of CPTED. This study proposes alternatives in policy necessary for CPTED, which is one of the strategies for crime prevention, to take its place as a useful strategy for making the urban societies safe and sustainable.

This study shows that the role of residents in landscape management is becoming increasingly important. The purpose of this study is to suggest elements that can continue the operation of landscape agreements and directions for promoting them. Therefore, 1)the operational elements considering the sustainability of the landscape agreements were proposed by way of literature research, expert interviews, and surveys. 2)The sustainable operation of elements of the landscape agreement were applied and best practices were developed through interviews with participants and literature analysis. 3)The final plan operational elements considering the sustainability of the landscape agreements and the directions for implementation were presented. As for the results, it was first presented that the elements of continuous operation of the landscape agreement, consisted of 3 major categories, 10 subcategories, and 25 details. These include resident awareness, practical applicability, effectiveness of administrative means, securing the budget, maintenance, public relations, expert support, dedicated support organization, sustainability of participation, and resident participation and communication methods. It is a detailed list of items that should be considered in the preparation phase, maintenance phase, and conclusion phase. Second, it suggested the direction for the sustainable operation of the landscape agreements be highly backed by the residents, and after reaching consensus on a landscape agreement, it is necessary that the agreement is based on contents that the residents can execute themselves. In addition, it was found that there is a need for a system to prepare the basis for securing the budget for the continuity of work, preparation of the landscape agreements, and consultation and activity costs during the maintenance phase. In addition, continuous exchanges and capacity building among residents have signed landscape agreements, and step-by-step support from experts in accordance with the level of involvement of residents is necessary. Third, even if a landscape agreement is concluded in connection with public projects, it is understood that the residents have the capacity to participate and can continue to support the administration and experts to enable the continued operation of the landscape agreement.

Since the late 20th century, sustainability is one of the most pressing concerns for the security and well-being of our society when we are witnessing the rapid change in urban landscape patterns. Responding to this issue, the discipline of environmental designs including landscape architecture has also attempted to realize this concept in various ways. The purpose of this study lies in introducing and redefining the meaning of ecological aesthetics as an alternative "sustainable" design theory. This paper theoretically discusses about the role of aesthetics in landscape design and the relationship between landscape and aesthetics to emphasize the importance of ecological aesthetics. Based on extensive literature review and analysis, the study attempts to redefine the characteristics of ecological aesthetics: an emphasis on cognitive process in landscape appreciation, environmentalism, unrestricted from style, and nonnative aesthetics. Having defined the characteristics, this study also finds several design subjects to adapt the concept of ecological aesthetics to actual design practice. Founded on the big idea "make nature visible", the defined subjects are ecological functions, temporality of landscape, and history of landscape, security, and accessibility. Also, this study stresses the importance m the creativity of the design(er) in order to effectively represent these subjects to the public.

As we enter the 2000s, there are four nuclear power units of the pressurized heavy water reactor-type in the commercial operation at the Wolsung Nuclear Power Plant(NPP) site where a larger amount of tritium ($\^$3/H) is released inevitably to the site environment. This radioctive nuclide is easily distributed throghout our environment because of its ubiquitous form as tritiated water (HTO) and its persistence in the environment. Tritum has certain characterisitics that present unique challenges for beta radiation dosimety and health risk assesment. In this paper, therefore, a variety of matters on tritium are considered and reviewed in terms of its characteristics and sources, metabolism and dosimetry, microdosimetry, radiobiology, risk assessment, and transport and cycling in the environment, etc.

The surface hydrology of large land areas is susceptible to several preferred stable states with transitions between stable states induced y stochastic fluctuation. This comes about due to the close coupling of land surface and atmospheric interaction. An interesting and important issue is the duration of residence in each mode. Mean transtion times between the stable modes are analyzed for different model parameters or climatic types. In an example situation of this differential equation exhibits a bimodal probability distribution of soil moisture states. Uncertainty analysis regarding the model parameters is performed using a Monte-Carlo simulation method. The method developed in this research may reveal some important characteristics of soil moisture or precipitation over a large area, in particular, those relating to abrupt changes in soil moisture or precipitation having extremely variable duration.

The air transport industry is the most important as means of human exchange between the countries. Because the spread effect and the durability by aviation cooperation between the countries are much higher than any other industry, a research about air transport industry is very important to allied industry field as well as national policy about International cooperation and integration. Specially, according to the economic interchange with North Korea becomes active, the role of air transport as related traffic network with North Korea becomes more important. The number of flights is increasing sharply after South-North summit meeting, and two sides established and are using temporary direct route between South-North Korea. When we consider that the number of flights utilizing temporary direct route is increasing every year, It is not desirable to use temporary routes continuously because the current agreement between South and North cant be reliable far the case of unexpected circumstance. In addition, the current agreement is not based on the international standards. The paper is to study the condition to promote the coordination of civil aviation in the whole Korean peninsula. As known, the aviation system in North Korea is mainly operated by military unit. The study will review the current status of air transport system of South and North and the effective way of cooperation of civil aviation between both sides. The cooperation between governments as well as between airlines is studied. The establishment of Air Traffic Service Agreement is going to be handled heavily because the stable air traffic service is the most required base for the operation of air transport. The authors also try to find a way to support the development of infrastructure of aviation industry in North Korea.

중금속의 경우 몇가지 약재에 있어서 중국산과 경북산의 뚜렷한 차이는 없었으나 산약과 작약의 경우는 중국산이 중금속 함량이 높았으며 시호와 천궁의 경우는 경북산이 중금속 함량이 높았다. 그러나 이들 약재로 인한 결과를 전체 중국산과 국내산의 비교 값으로 대표 할 수는 없다. 한약재에 함유된 무기질과 중금속 함량간의 유의성을 검정하여 상관관계를 확인하려 했으나 약재간의 특이성과 무기질 및 중금속간 흡수능의 차이로 인한 뚜렷한 상관관계를 검정하기가 어려웠다. 한약재에서 생체내에서 중요한 필수 무기질에 대한 분석은 안전성과 규격화를 위한 필요한 기초연구이며, 이에 관한 데이터뱅크가 마련된다면 한약재에 함유된 무기질의 영양학적 가치를 통해 질병의 예방과 치료에 중요한 정보원으로 유용성을 확보할 수 있으므로 좀더 많은 연구가 광범위하고 지속적으로 수행되어져야 할 과제라고 사료된다.
