In this research, a River Recreation Index Model (RRIM) was developed to provide sufficient information on the water quality of rivers to the public in order to secure safety of publics. River Recreation Index (RRI) is an integrated water quality information for recreation activities in rivers and e...

분변성 대장균은 어떤 인자들과 상관관계를 보이는가? | 분변성 대장균은 여러 수질인자, 유량, 기상 인자들과 상관관계를 보인다고 알려져 있으므로 이러한 상관관계에 중점을 두고 로지스틱 회귀분석을 통해 FCG를 예측하도록 FCM을 개발하였다. 로지스틱 회귀분석은 일반적인 선형회귀분석과는 달리 종속변수가 0과 1, 혹은 좋음과 나쁨과 같은 형태의 범주형 변수일 때 사용되는 방법이다. | |
하천의 수질이 수상활동에서 중요하다는 것을 보여주는 예는? | 하천 레크리에이션 중 수영, 보트, 수상스키와 같이 수체와의 접촉을 유발하는 활동에 있어서 하천의 수질은 수위, 유속 등의 수리학적 인자와 더불어 가장 중요한 요소이다. 수질이 나쁜 경우, 하천 레크리에이션 활동 중 수체와 접촉하여 수인성 질병이 발발할 수 있으며, 소화기 장애, 눈과 피부의 질병 등이 발생할 수 있다. 이처럼 하천의 수질은 수상 활동에 있어서 매우 중요하기 때문에, 하천 관리 기관은 시민들이 안전하게 하천 레크리에이션을 즐길 수 있도록 수질에 대한 적절한 정보를 제공할 필요가 있다. | |
미국에서 운영되고 있는 레크리에이션에 필요한 수질 정보를 제공하는 예측․ 예보 시스템은? | 수상 레크리에이션이 발달한 국가에서는 레크리에이션에 필요한 수질 정보를 제공하는 예측․ 예보 시스템이 적극적으로 운영되고 있다(Table 1). 먼저 미국에서 대표적으로 Massachusetts주의 Flagging program, Ohio주의 Nowcasting beach advisories, Philadelphia주의 Philly Rivercast 등이 운영되고 있다. Table 1에 나타난 바와 같이 이 시스템들에서는 수영 혹은 보트와 같이 수체와 직접 혹은 간접접촉을 필요로 하는 활동에 대해 안전한 조건을 제시하고 있으며, 이 때 주요 예보 인자로서 수인성 질병과 상관관계가 높다고 알려진 대장균 농도를 제시하고 있다. |
