본 연구에서는 주요 수문 변수인 유출량, 저수위, 유량 등의 관측 자료가 부재한 미계측 유역에 대한 수문학적 가뭄 평가 및 감시를 위해 원격 탐사 자료를 활용하는 방법론을 최근 심각한 가뭄 피해를 입은 지역인 남한강상류 유역에 적용하였다. 수문 변수의 관측 자료가 부재한 지역에 대해서는 원격 탐사를 이용하여 수문 변수보다 추정이 용이한 강수량, 증발산량 등 기상 변수의 추정을 통해 물 수지에 기초하여 가뭄 상태에 대한 정보를 얻을 수 있다. 본 연구에서는 2002-2013년의 기간에 대하여 원격 탐사 자료를 이용하여 대기의 온도를 추정하고, 이로부터 증발산량을 도출하여 강수량과 증발산량 차의 백분위가 유량 백분위와 가지는 상관성을 분석하였다. Aqua위성에 탑재된 MODIS 센서의 1×1 km 공간 해상도의 지표면 온도와 5×5 km 공간해상도의 대기 연직 온도 자료를 이용하여 월별 최고 및 최저 대기 온도를 추정하였으며, Hargreaves 방법을 이용하여 증발산량을 추정하였다. 미국몬태나주립대학교에서 Penman-Monteith 방법을 이용하여 추정한 기존 자료(MOD16)의 잠재 증발산량과 비교한 결과 상대적으로 결정계수는 더 작았으나 상당히 작은 오차를 보였다. 남한강상류 유역에 대하여 TRMM 위성으로부터 도출한 강수량과 함께 1, 3, 6, 12개월 시간 척도의 P-PET(강수량·증발산량) 백분위를 구해 유량 백분위와의 상관관계를 분석하였다. 남한강상류 유역은 여름철(r = 0.89, tau = 0.71)과 가뭄 평가에 중요한 가을철(r = 0.63, tau = 0.47)에 1개월 P-PET 백분위가 유량 백분위와 95% 신뢰도로 통계적으로 유의한 높은 상관관계를 나타냈다. 이 유역은 강수의 영향이 특히 크게 나타나는 지역으로 일반적으로 건조한 지역과는 달리 증발산량이 유량과 양의 상관관계를 보였다. 연구 결과로부터 원격 탐사 자료가 미계측 유역에서 수문학적 가뭄 평가 및 감시에 유용하게 활용될 수 있음을 보였으며 특히 공간적으로 분포된 높은 해상도의 추정 자료는 지역별로 차별화된 가뭄 대책 수립에 기여할 수 있을 것이다. In this study, a method to assess and monitor hydrological drought using remote sensing was investigated for use in regions with limited observation data, and was applied to the Upper Namhan-gang basin in South Korea, which was seriously affected by the 2008-2009 drought. Drought information may be obtained more easily from meteorological data based on water balance than hydrological data that are hard to estimate. Air temperature data at 2 m above ground level (AGL) were estimated using remotely sensed data, evapotranspiration was estimated from the air temperature, and the correlations between precipitation minus evapotranspiration (P-PET) and streamflow percentiles were examined. Land Surface Temperature data with 1 × 1 km spatial resolution as well as Atmospheric Profile data with 5 × 5 km spatial resolution from MODIS sensor on board Aqua satellite were used to estimate monthly maximum and minimum air temperature in South Korea. Evapotranspiration was estimated from the maximum and minimum air temperature using the Hargreaves method and the estimates were compared to existing data of the University of Montana based on Penman-Monteith method showing smaller coefficient of determination values but smaller error values. Precipitation was obtained from TRMM monthly rainfall data, and the correlations of 1-, 3-, 6-, and 12-month P-PET percentiles with streamflow percentiles were analyzed for the Upper Namhan-gang basin in South Korea. The 1-month P-PET percentile during JJA (r = 0.89, tau = 0.71) and SON (r = 0.63, tau = 0.47) in the Upper Namhan-gang basin are highly correlated with the streamflow percentile with 95% confidence level. Since the effect of precipitation in the basin is especially high, the correlation between evapotranspiration percentile and streamflow percentile is positive. These results indicate that remote sensing-based P-PET estimates can be used for the assessment and monitoring of hydrological drought. The high spatial resolution estimates can be used in the decision-making process to minimize the adverse impacts of hydrological drought and to establish differentiated measures coping with drought.

As a number of archaea are ubiquitously found in non-extreme habitats, elucidation of their functional roles becomes currently an emerging issue. However, most of them are unable to grow in pure culture and so it remains to be established. In order to find genes lacking in the genome of an ammonia-oxidizing archaeon (AOA), we here report on the comparative analyses of an AOA genome with those of experimentally or theoretically established minimal genomes for independent growth. We assessed the genes lacking in AOA using logic of clusters of orthologous groups (COG), remote homology, consensus sequence weight matrix, function-based motif or domain, and then further excluded genes encoding hypothetical orarchaea-specific proteins. The results of these combination analyses revealed 19 candidate genes lacking in the genome of an AOA. Thus, our results provide a possibility of inducing independent growth of AOA when supplemented with product (s) of the lacking gene (s), and also give a chance for finding new proteins with novel sequence or structure space even if the predicted lacking-genes will be found using another algorithms or biochemical studies.

본 연구는 CMIP5 (Coupled Model Intercomparison Project Phase 5) 다중 모델 앙상블 기후변화 시나리오를 바탕으로 우리나라의 토사재해 위험이 높은 지역에 대한 미래 강우전망 불확실성을 분석하였다. 사용된 GCM (General-Circulation Models) 모형은 총 9개이며, 기후변화 시나리오의 편이 보정을 위해 비 매개변수적 Quantile Mapping 방법을 사용하였다. 또한 Gumbel 분포형을 적용하여 연최대치 계열에 대한 재현기간별 확률강우량을 산정하였으며, 강우강도와 지속시간별 확률강우량 곡선을 작성하였다. 분석결과 토사재해 위험지역의 연최대 강우량은 관측기간에 비하여 RCP4.5 시나리오에서는 17.3% 증가, RCP8.5 시나리오에서는 20.1% 증가하였으며, RCP8.5 시나리오에서 그 증가 기울기가 큰 것으로 분석되었다. 또한 재현기간별 확률강우량은 RCP4.5 시나리오에서 최대 -3.1~29.9% 편차를 보이며 증가하였고, RCP8.5 시나리오에서 2.7~38.7% 편차를 보이며 증가하였다. 본 연구의 결과는 미래 기후변화 조건에서의 토석류해석 및 토사재해 위험예측을 위한 강우 입력 자료로 활용할 수 있을 것이다. This study analyzed uncertainty of future extreme rainfall over the landslide high risk zones in the Korean Peninsula (KP) by Coupled Model Intercomparison Project Phase 5 (CMIP5) based on Multi-Model Ensemble climate change scenarios. The nine-General Circulation Models (GCMs) were used for projection of precipitation and the non-parametric quantile mapping method was used for bias correction of climate change scenarios. The probable precipitation was calculated by optimal Gumbel distribution, and we obtained intensity, duration, and frequency curves in each return period over the landslide risk zones. As a result of this study, the annual maximum precipitation in landslide risk areas increased by 17.3% (20.1%) in the RCP4.5 (RCP8.5) scenarios, and the slope of the increasing tendency was largely analysed in the RCP8.5 scenario. In addition, the probability rainfall by return periods increased by a maximum of -3.1~29.9% in the RCP4.5 scenario and by 2.7~38.7% in the RCP8.5 scenario. The results of this study can be used as precipitation input data for the analysis of debris flow and the landslide hazards analysis under the conditions of future climate change.
