지진 발생 시 지진으로 인한 피해를 최소화하기 위해서는 지진 발생 이전의 재난 대비와 발생 이후의 복구계획 수립이 중요하다. 특 히 효과적인 대응체계 마련을 위해서는 심각한 피해가 예상되는 건축물을 대상으로 지진위험도를 평가하여 건축물의 피해를 예측하 는 과정이 지역사회를 단위로 수행되어야 한다. 본 논문에서는 건축물의 취약도와 지반운동이 결합되어 결정되는 지진위험도를 평 가하기 위해서 공학적으로 정량적으로 판단할 수 있는 지진 붕괴위험도의 개념을 활용하여 지역단위 평가를 수행하였다. 평가 결과, 행정구역 내 건축물의 구조유형 분포는 해당 지역 붕괴위험도 평가에 유의미한 영향을 미침을 확인하였다. 그러나 일부 지역에서는 구조유형만으로 설명할 수 없는 양상을 보였는데, 이는 지반종류에 따른 영향이 지역단위 붕괴위험도 평가에 있어 미치는 영향이 상 대적으로 크다고 판단할 수 있으며, 합리적인 평가결과 도출을 위하여 건축물의 내진성능에 의한 붕괴위험도와 반드시 함께 고려될 필요가 있음을 설명한다.

The World Vegetable Center (WorldVeg) maintains the world’s largest public vegetable germplasm collection. The Genebank contains over 65,000 accessions and consists of more than 130 genera and 330 species. It includes around 12,000 accessions of indigenous vegetables. The WorldVeg Korea Office (WKO) has been conducting regional adaptability evaluations in the fields of the National Institute of Horticultural and Herbal Science (NIHHS), with a focus on major solanaceous vegetable crops such as tomato, chili, and bell pepper. As climate change significantly affects vegetable crop productivity, the development of high-performing cultivars, tolerant to various abiotic and biotic stresses with enriched nutrients inside, is essential to enhance agricultural sustainability and human health. In this regard, the evaluation of growth and horticultural characteristics of pepper and tomato accessions from the WorldVeg will help contribute to the generation of new and improved cultivars, to address global challenges that affect food security, sustainability, and adaptation to climate change. Here, we summarize our activities and the results of the regional adaptability evaluation using the WorldVeg accessions of pepper and tomato germplasms.

본 연구는 영국기상청에서 개발된 지역기후모델 Hadley Centre Global Environmental Model version 3 regional climate model (HadGEM3-RA)로부터 모의된 동아시아 지역의 기온과 강수 결과를 평가하였다. HadGEM3-RA 는 Coordinated Regional climate Downscaling Experiment-East Asia (CORDEX-EA) Phase II 영역에서 15년 (2000- 2014년) 모의되었다. 동아시아 여름 몬순에 의한 HadGEM3-RA 강수대 분포는 Asian Precipitation Highly ResolvedObservational Data Integration Towards Evaluation of water resources (APHRODITE) 자료와 잘 일치한다. 그러나, 동 남아시아 강수는 과대 모의하며 남한에서는 과소 모의한다. 특히 모의된 여름철 강수량과 APHRODITE 강수량은 남한 지역에서 가장 낮은 상관 계수와 가장 큰 오차크기(RMSE)를 보인다. 동아시아 기온 예측은 과소 모의하며 겨울철 오 차가 가장 크다. 남한 기온 예측은 봄 동안 가장 큰 과소 모의 오차를 나타냈다. 국지적 예측성을 평가하기 위하여 서 울기상관측소 ASOS 자료와 비교한 기온과 강수의 시계열은 여름철 강수와 겨울철 기온이 과소 모의하는 공간 평균된 검증 결과와 유사하였다. 특히 여름철 강수량 증가시 과소 모의 오차가 증가하였다. 겨울철 기온은 저온에서는 과소 모 의하나 고온은 과대 모의하는 경향이 나타났다. 극한기후지수 비교 결과는 폭염은 과대 모의하여, 집중호우는 과소 모 의하는 오차가 나타났다. 수평해상도25km로 모의된 HadGEM3-RA는 중규모 대류계와 지형성 강수 예측에서 한계를 보였다. 본 연구는 지역기후모델 예측성 개선을 위한 초기 자료 개선, 해상도 향상, 물리 과정의 개선이 필요함을 지시 한다.

This study would present a risk analysis method to evaluate stable tap water supply in a multi-regional water supply system and propose a measure for the evaluation of the effect of the conjunctive operation of the multi-regional water supply system using this. Judging from the vulnerability for the crisis response of the entire N. multi-regional water supply system, as compared to the result of Scenario 1 in which no conjunctive pipes were operated, it was found that in Scenario 2, in which conjunctive pipes were partially operated, the vulnerability of crisis response decreased by about 30.6%, and as compared to Scenario 3, the vulnerability of crisis response decreased by 86.2%. In setting a plan for stable tap water supply in N multi-regional water supply system, using the estimated value and the method for the evaluation of the vulnerability of crisis response by pipe, by interval and by line, it is judged that this can be utilized as a basis for the judgment of the evaluation of the operation or the additional installation of conjunctive pipes.

최근 강우 발생빈도의 불규칙한 변화로 홍수 및 가뭄 피해가 증가함에 따라 불규칙한 자연현상의 특 성을 예측하는 확률론적 방안들이 관심을 받고 있다. 본 연구에서는 자연계 현상을 확률론적으로 예측 하는 기법인 플랙탈이론의 허스트지수(Hurst exponent)를 이용한 자기유사성 평가를 전국 64개 기상관 측소의 월강수량 자료를 대상으로 실시하였다. 1986년부터 2015년까지 총 30년 동안의 월강수량을 평 가한 결과 허스트지수는 H=0.97~0.99의 범위로 나타났다. 이는 H>1/2의 양의 상관관계를 보이며, 자 기유사성을 가지는 것으로 평가될 수 있어 기존의 축척된 자료를 통해 향후의 이상강우에 대한 예측이 가능하다는 사실을 보여주는 것으로 나타났다.

Although the Hazen-Williams C factors are very important in the design, operation, and maintenance of water supply pipes, sufficient studies for them have been not reported in korea, which are based on experiments or measured data. Because of this, we have estimated C factors by measurement considering constraints in time precise safety diagnosis for multi-regional water supply system were performed. In this study, we confirmed constraints and variables characteristics of Hazen-Williams equation, and collected reliable C factors data of 174 by measurement, and analyzed their characteristics. According to collected data, the average value is 115.35, which is almost equal to the value of design standard or a little higher than it in korea. Also, among the equations suggested to determine C factor in the past, the C factors calculated by Sharp and Walski equation was closest to them in this study. In addition, to analyze collected C factors, use year and pipe diameter having high correlation with them were respectively divided into there categories. Analysis results showed that C factors evidently decreases depending on increases in use year, on the other hand, size of pipe diameter is proportional to value of them. In conclusion, this research showing evaluation and characteristics for C factors based on measured data will be used as practical reference in determining C factor in multi-regional water supply systems at a later date.

To find characteristics and areas of greater risk of oil spill at the coastal waters in Korea, some of risk factors were analyzed with historical data of oil spill and marine traffic. As a result, it is characterized that frequency of oil spill is increasing year by year and greatest percentage of spill source is fishing boat. It is proposed that the ports of Ulsan, Yeosu, Incheon and Pusan will be designated as primary area of risk as they have a higher risk of oil spills and its response authority is required to maintain appropriate regional response capability for prompt and effective response to a future spill incident. In addition, the regional response equipments at Ulsan are examined under a assumption of a medium size spill and it is found that the use of chemical dispersant can be an alternative when mechanical containment and recovery is not feasible in this area, and the existing response equipments may be appropriate to address that size of spill. However, the response authority is required to maintain more numbers of stronger boom for unsheltered waters and more quantity of concentrate dispersant to disperse all spilled oils on the water, furthermore the response authority should be prepared for a possible future catastrophic spill with sufficient equipments.

The paper proposes a knowledge innovation performance model by the dynamic data envelopment analysis with slacks-based measure approach for evaluating the effectiveness of 30 regional knowledge innovation activities in China from 2010 to 2016. In recent years, China has paid more attention to knowledge innovation activities, as central and local governments have pushed on with their innovation projects by lots of investment whatever the difficulties may be. Decision-maker is usually interested in judge its knowledge innovation performance relative to target benchmark by exploring whether one provincial administration region performs better among others and/or if the growth of economy will be benefited greatly by the knowledge innovation activities. To acquire the managerial insight about this issue from a comprehensively designed performance evaluation model, knowledge innovation activity is conceptualized as an intertemporal production process. Invention patent and regional gross product are imposed on desirable outputs, highlighting the need for knowledge economy. The empirical result shows that knowledge innovation has a positive effect on economic development. At the same time, decision-maker should be interest in the economic effect of patents’ type and quality. The government should then encourage new technical applications with greater commercial value from a market-oriented perspective, in order to benefit the most from the innovation process in the short-run.

The Ministry of Unification has published the North's social and economic indicators about 'North Main statistical indicators' every years. However, "North Main Statistical Indicators" does not reflect the status and the level of North Korean infrastructure. The purpose of this study is to survey maintenance status and level of North Korean infrastructure, and to propose a regional assessment results.

We examined temporal and spatial structure of trends in precipitation-based and temperaturebased extreme indices simulated by the Regional Model Program of Global/Regional Integrated Model System (GRIMs-RMP). The extreme indices were selected to consider the frequency, intensity, and persistence of extreme events. During the Last 30 years from 1979 to 2008, the model reasonably have simulated the temporal and spatial pattern of the trend. Although overestimation of minimum temperature and underestimation of maximum temperature occured, the regional climate model captured observed direction and magnitude well in the indices based on temperature. The indices related to rainfall tended to be overestimated over East Asia except for Korea and Japan. However, the trend showd agreement with observation. the results allow us to be optimistic about the RCM ability in the simulation of important extreme event of precipitation and surface temperature in East Asia. This type of study can also provide meaningful climate statistics and insight into climate change impact study.

In order to clarify the contribution rate of PM concentration due to regional emission distribution, Brute force analysis were carried out using numerical estimated PM data from WRF-CMAQ. The emission from Kyeongki region including Seoul metropolitan is the largest contribution of PM concentration than that from other regions except for emission of trans-country and source itself. Contribution rate of self emission is also the largest at Kyeongki region and its rate reach on over 95 %. And the rate at Gangwon region also higher than any region due to synoptic wind pattern. Due to synoptic wind direction at high PM episode, pollutants at downwind area along from west to east and from north to south tends to mix intensively and its composition is also complicated. Although the uncertainty of initial concentration of PM, the contribution of regional PM concentration tend to depend on the meteorological condition including intensity of synoptic and mesoscale wind and PM emission pattern over upwind region.

In this study, as well as natural disasters, disasters caused by human factors, even disasters can consider integrated regional risk assessment aims at the development of techniques. Facility of one of its elements a disaster risk factor deriving method are described.
