This study aims to present promotion strategies for regional industries by exploring the ways to build industrial cluster focusing on regional strategic industries of Gyeongsanbuk-do(province) which are related to innovation city, by taking Gyeongbuk innovation city as an example. This study presented the methods for linking with innovation cities that focus on regional strategic industries, along with the analysis on the linkage between regional industries and public organizations relocated to local regions. As to the methods for the linkage, methods to build clusters based on the characteristics of each industry, such as electronic information device, new material parts, biological oriental medicine, cultural tourism, eco-friendly energy, etc, which are strategic and leading industries of Gyeongsanbuk-do(province), were presented. It was inferred that the industries which have achieved fast growth such as IT and BT industries, required mutually interconnected collaboration through geographical proximity among related subjects, while sectors with mature technologies, such as automative parts, machinery, steel industries, etc, were found to require more extensive infrastructures like the support of transportation and distribution for promoting current clusters.

기후변화에 의한 강우패턴의 변화는 강우량 및 강우강도의 증가로 대표되며 국립기상연구소 (2011)에 의하면 현재와 같은 탄소배출이 줄어들지 않는다면 2050년 우리나라의 강수량은 16% 증가하고 일 강수량 80mm 이상의 호우발생일수가 60%이상 증가될 것으로 전망하고 있다. 이와 같이 기후변화로 인해 발생빈도가 증가추세인 집중호우는 산사태와 같은 2차 피해를 유발하고 있으며 강우의 예측 및 실시간 모니터링은 재해 예방 및 수자원관리, 국가 방재역량 강화를 위해 연구되어야 할 분야이다. 이에 본 연구에서는 광역적 강우자료로서 미국 NOAA의 기후예측센터에 의해 제공되는 글로벌 강우량 CMORPH와 지상 강우자료와의 비교 분석을 통해 CMORPH 자료의 수자원 분야 이용 가능성을 분석하는 것을 목적으로 한다. CMORPH는 고급의 시공간적 해상도를 가지며, 단기간의 기후 예측센터 모핑(morphing) 방법에 의한 "CMORPH"라 불리우는 강우평가 알고리즘과 새로운 위성 기반 기술을 이용하여 개발되었다. CMORPH 기술에 의해 생산된 글로벌 강우 추정은 저궤도 위성 수동 마이크로파(passive microwaves, PMW) 관측으로부터 유도되고, 그 형태는 전적으로 정지궤도 위성(geostationary satellite) 적외선(IR) 데이터로부터 얻어진 공간적 전파 정보 (모션 벡터)를 통해 전송된다. 이 기술은 PMW 데이터로부터 유도된 비교적 고품질의 추정 강우를 전파하기 위하여 30분 간격의 정지궤도 위성 IR 이미지로부터 파생된 모션 벡터를 이용하며, 때때로 레이더보다 더 나은 성능을 보이기도 하고(Apip 등 2010), CMORPH의 지역적 제공범위는 $60^{\circ}N-60^{\circ}S$이고 2002년 12월부터 제공하고 있다. 본 연구에서는 CMORPH 자료 중 2002년 12월부터 제공하는 3시간 누가강우 자료를 수집하였고, 자료의 정확도 분석은 갑천유역을 대상으로 하였다. 3시간 누가 강우량을 1일 누가 강우량으로 변환한 후 금강홍수통제소의 갑천 유역 강우관측소 5곳의 강우자료를 티센 평균에 의한 유역 평균강우자료와 비교하였다. 2009년 1년간의 지상관측자료와 CMORPH자료를 비교한 결과 가 0.34 정도로 분석되었으나 추가 연구를 통해 마이크로 웨이브 강우자료 및 3시간 강우자료, 그리고 30분 강우자료의 분석을 통해 다양한 형태의 강우자료 확보뿐만 아니라 광역적인 강우특성 분석도 가능하여 연구 결과의 동아시아지역 등으로 확대 적용할 수 있을 것으로 기대한다.

The key to the long-term preservation of electronic records is the long-term retention of the bitstream that contains the original functional attributes and appearances of the electronic records that were originally created and utilized. Considering economic and technical aspects, most of the major domestic and foreign archives have adopted a migration strategy that allows conversion to a new format depending on the stability and reliability of the format containing the original bitstream. However, as the type of electronic records varies and its scope continuously expands, several problems arise if a single migration strategy is observed. Therefore, the applicability of the emulation strategy is examined in this paper to reproduce the system and application environment where electronic records are created and utilized. As such, electronic records can be maintained without any changes in the bitstream by utilizing cloud computing technology.

With the worldwide spread of African swine fever, interest in livestock epidemics is growing. Livestock transport vehicles are the main cause of the spread of livestock epidemics, but no empirical quarantine procedures and standards related to the mobility of livestock transport vehicles in South Korea. This study extracted livestock-related vehicles' trajectory by utilizing the facility visit history data from the Korea Animal Health Integrated System and the DTG (Digital Tachograph) data from the Korea Transportation Safety Authority and presented them as exposure indexes aggregating the link-time occupancy of each vehicle. As a result, a total of 274,519 livestock-related vehicle trajectories were extracted, and exposure values by link and zone were quantitatively derived. Through this study, it is expected that prior monitoring of livestock transport vehicles and the establishment of post-disaster prevention policies would be provided.

General circulation models(GCMs)은 여러 국가 기관들의 물리적 기후 모의 프로세스를 기반으로 과거 및 미래 기후변화의 영향을 정량화하기 위해 개발되었으며 현재 미래 기후변화를 예측하는데 가장 효과적인 도구이다. 그러나 GCMs에 내포된 여러 불확실성 요소 및 넓은 격자형식의 기후 데이터는 GCMs 기후 데이터를 사용한 지역적 기후 모의 시 주요 걸림돌로 인식되어지고 있다. 편의보정 방법은 GCMs을 사용한 지역적 기후 모의 시 기후 모의 성능을 향상시키기 위해 여러 연구에서 사용되어져 왔으나 다른 연구에서는 이러한 편의보정 방법의 문제점을 언급했다. 따라서 본 연구는 편의보정 방법이 GCMs 기후 모의 결과에 미치는 영향을 정량화하고 더 나아가 GCMs 기후 변수에 따른 유량 모의 결과에 미치는 영향을 분석했다. 연구대상지 과거 기간 기후 모의를 위해 coupled model intercomparison project(CMIP)6의 GCMs을 사용했으며, 미래 기후 모의를 위해 shared socioeconomic pathway(SSP) 시나리오를 사용했다. 편의보정 방법으로는 분위사상법을 사용했으며, 편의보정 전후 GCMs 기후 모의 성능평가를 위해 5개 평가 지표를 사용했다. 연구대상지 장기 유출 모의를 위해 storm water management model(SWMM)이 사용되었으며, 기후 입력 자료로는 일 단위 강수량, 최고 및 최저온도를 고려했다. 미래 기후 및 유량 모의 결과의 불확실성은 square root of error variance(SREV) 방법을 통해 정량화됐다. 결과적으로 과거 기간 GCMs 기후 및 유량 모의성능은 편의보정 전보다 편의보정 후에서 향상되었으며 특히, 강수 및 유량 모의 성능이 크게 향상되었다. 미래 기간의 경우 편의보정 후에서 기후 및 유량의 극값을 더 잘 반영함을 확인했다. 본 연구의 결과는 GCMs 기후 변수를 사용한 지역적 기후 및 유량 모의 시 편의보정 방법이 미치는 영향에 대한 구체적인 정보를 제공할 수 있다.
