As the domestic animation industry is shrinking, it is time to actively respond to changes in new technologies and animation production methods. From 2016 to 2020, through patent information registered in the United States, China, and Korea in the field of animation technology, applicants who are the subject of technology were analyzed and technical policies and strategies pursued by applicants in each country were reviewed. China registered the most patents, so the technical activity index was high, and the US family patent size was high. As a result of positioning analysis, the U.S. market expansion influence decreased over time, China's technological activity gradually increased over time, and Korea's technological activity and family patent size decreased. Reflecting China's rise as the world's largest animation producer, Korea should also develop a policy to support animation.

The purpose of this study is to compare traditional productivity and environmental productivity of Chinese 28 provinces for 1997-2005. The Eastern, the Central and the Western regions show higher M productivity indices than ML productivity indices before 2000 year, but two productivity indices of three regions report almost similar levels after 2000 year. The M productivity indices were higher than the ML productivity indices in the most provinces for 1997-2005. It implies that the Chinese regional economies have difficulties in the production activity reducing pollutants and increasing desirable outputs simultaneously. In the future, the Chinese 28 provinces need to change the direction of economic growth in the way that pursuits economic growth restraining pollution emission quantities thoroughly and should improve the concrete investment for clean technology of pollutant treatment, reinforcement of environmental regulation, and effectiveness of enforcement law.

ICT sector has been made a great deal of achievements for past 20 or more years in the aspects of the industrial promotion and the efficiency improvement under the strong leadership by the government for the informatization and still leads the Korean industries. However, the previous studies are mostly on how the quantitative growth of patents impacts a company's management achievements while being insufficient on the qualitative level. In this study, an analysis is attempted on the impact from the qualitative level of patents held by a ICT company leading Korean industry to its management achievements. In other words, if the concentration of technological innovation activities, a scale to measure the qualitative level of possessed patents is influential to the growth and the profit of a company is analyzed. The analysis result shows that the current time technological superiority index, RTA and the concentration index, CRn of the technological innovation activities significantly impact to the growth and the profit of company. This study demonstrates the positive impact from a highly qualitative level of patents to the growth and the profit of a company in ICT sector in the current circumstance of insufficient researches on the qualitative level of patents. Therefore, this study is expected to present a new start point for the future studies.

Despite the facts that navigation technology and educational programs were developed, and that maritime law has been enforced strictly, the number of maritime accidents has not dropped significantly. Accident prevention is emphasized because of the extreme life, property, and environmental losses that accompany maritime accidents. Even though there are a variety of preventive activities, their performance is not satisfactory. In order to promote preventive activities and to organize safety management, a Preventive Index of Ship Accident(PISA) and a Preventive Level of Ship Accident(PLSA) which are abstracted from the statistical data of ship accidents (2009~2013) are proposed. The survey module by which these variables can be calculated is composed of preventive domains such as education, engineering, enforcement and information, and is applied for the preventive indexes measurement of cargo, passenger, tanker, tugboat and fishery ships. We compared and analyzed measured result with statistical accident rates and cases to confirm the index utilities. It was found that there is some correlation between the index value and the ship accident rate. It is expected that this index will become useful to evaluate a preventive status for the prevention of ship accidents and for the maritime safety culture.

제방이 제 기능을 발휘하기 위해서는 홍수나 범람 등에 얼마나 견딜 수 있는지를 알아야 한다. 그러기 위해서는 무엇보다도 제방이 자연재해로부터 손상을 입게 되는 원인과 과정, 하천수의 침투로 인한 제체내부의 역학적 거동 등에 대한 충분한 이해와 지식을 함양해야 한다. 본 연구에서는 하천 제방에 대한 홍수취약성을 평가하는 새로운 기법을 제시하고 기후변화에 따라 변화하는 수위에 대하여 제방에 미치는 영향을 분석하였다. 이를 위해 먼저 2차원 지하수침투 모형인 SEEP/W를 이용하여 제방의 침투거동을 분석하여 침투안전성을 평가하였다. 침투거동뿐만 아니라 기후변화에 따른 하천환경여건을 고려하는 제방의 취약성 분석 기술이 필요함으로써 본 연구에서는 추가적으로 제방의 취약성 분석에 필요한 인자를 도출하여 제방의 홍수취약성지수(levee flood vulnerability index； LFVI)에 의한 취약성 평가기법을 새로이 개발 하였다. 대상지역을 국가하천과 지방하천으로 구분하였다. 이들 대표 제방지점에서 현재의 계획홍수위와 기후변화 시나리오 RCP8.5를 고려한 계획홍수위를 적용하여 제방의 활동 안전율과 제방홍수취약성지수를 분석하였다. 그리고 제방홍수취약성지수를 구성하는 각각 인자들에 대하여 기후변화에 따른 변화 정도를 파악하였다. 이들 인자들을 종합적으로 활용한 제방홍수취약성지수 값을 이용하여 최종적으로 기후변화에 따른 제방의 취약성을 추정할 수 있도록 하였다.

This paper introduces a relative comparative advantage index and a composite concentration index of university research activity in science and technology. Three hypotheses were tested regarding differences of degree of concentration based on the size of government R&D fund, location of university, and source of foundation, respectively. T-test results imply that there are significant differences of concentration based on the size of R&D fund and source of foundation, while location of university does not show a significant difference. The paper generally suggests that the lesser size of government R&D fund would lead higher level of concentration, and public funded universities tend to maintain far higher concentration ratio. The paper contributes by introducing relevant indexes for analyzing university research competence, concentration and competitiveness, and hence by proposing policy direction and implication for university competitiveness policy.

본 연구에서는 증발산, 토양수분, 태양복사에너지, 식생 활동 등과 같은 수문기상인자들을 활용하여 새로운 가뭄 지수(Energy-based Water Deficit Index(EWDI)를 개발하였고 이는 Moderate Resolution Imaging Spectroradiometer(MODIS)에서 제공되는 산출물들을 활용하였다. EWDI는 물의 순환과 탄소 순환을 동시에 고려하여 기존에 활용되는 다른 가뭄지수들보다 다양한 측면에서 가뭄을 분석할 수 있는 장점을 가지고 있으며 산정된 EWDI는 증발산 기반의 가뭄지수인 Stand-alone MODIS-based Evaporative Stress Index(stMOD_ESI)와 함께 시공간적인 변동성을 비교하여 전 세계적으로 가뭄 피해가 심각한 지역인 몽골, 호주, 한반도 지역에 대해 2000년에서 2010년까지 적용성을 파악하였다. 또한, 본 연구에서는 각 지수들 간의 상관관계를 파악하고 수문기상 인자들과 가뭄 현상 사이에 관계성을 파악하기 위해 Receiver Operating Characteristics(ROC) 분석을 수행하였다. 위에서 언급한 여러 분석 결과를 토대로, EWDI와 stMOD_ESI는 기존에 많이 쓰였던 가뭄 지수인 표준강수지수(Standardized Precipitation Index, SPI)에 비해 가뭄 상태를 더욱 잘 파악할 수 있는 것으로 나타났으며 EWDI와 stMOD_ESI가 광역적인 범위에서의 적용성이 높음을 파악하였다. 본 연구를 통해 수문기상학 및 수자원 분야에서의 인공위성을 활용한 가뭄 분석 연구의 기틀이 마련되길 기대해 볼 수 있다.
