비점오염원은 강우시 토지이용형태에 따라 유출특성이 다양하게 나타나며, 특히 강우 초기에 고농도의 유출수가 수계로 유입하게 된다. 또한 강우량, 강우강도, 선행건기일수 등은 비점오염물질의 농도에 영향을 미치며, 특히 선행건기일수가 길고 강우강도가 강한 강우사상일 경우 고농도의 오염물질이 배출되는 것으로 나타나고 있다(안태웅 등, 2012). 이에 본 연구에서는 3년간(2010년 ~ 2012년)의 모니터링을 통해 고랭지 밭에서 발생하는 비점오염물질의 초기세척효과를 분석하고자 하였다. 초기세척효과의 판단은 Geiger(1987)이 제시한 누적오염부하량과 누적유출량과의 그래프를 비교하여 기울기가 45도 기울기보다 상향하여 분포하였을 경우 양분선과 최대로 벌어진 부분의 시간까지에서 초기세척효과가 발생한다고 판단하였다. 연구결과, 고랭지 밭 지역의 경우 뚜렷한 초기세척효과 현상이 나타나지 않았다. 하지만 CODCr의 경우 3차 강우사상에서 초기세척 효과가 나타난 것으로 분석되었다. 3차 강우사상은 선행건기일수가 0.9일로 매우 짧고 발생강우량이 27.3 mm로 연구기간 동안 가장 적은 강우량이 관측되었지만, 유출발생시점 전후 3시간 동안 강우강도가 4.0 ~ 6.2 mm/hr로 높게 나타났기 때문에 유출초기에 고농도의 오염물질이 발생된 것으로 판단된다. 그동안 선행된 초기세척효과에 대한 연구를 살펴본 결과 이병수 등(2008)은 경안천 유역 농업지역에 대해 초기세척효과를 분석한 결과 일부 강우에서는 초기세척현상이 나타나지만 대부분의 강우에서는 초기세척현상이 나타나지 않아 농촌지역의 경우 초기세척현상의 접근방법은 적절치 않다고 보고하고 있다. 정성민 등(2009)은 고랭지 농업지역에서 SS와 TP는 뚜렷한 초기세척현상이 나타나는 반면, TN과 DOC는 경향을 보이지 않는다고 하였다. 하지만 윤영삼 등(2011)은 강우시 포도밭에서 초기세척효과를 분석한 결과 모든 수질항목에서 약한 초기세척효과가 나타났고 특히 SS의 경우 초기세척효과가 강하게 나타났다고 보고하고 있다. 이처럼 투수지역에서의 초기세척효과에 대한 판단은 연구자에 따라 차이를 보이는데 이러한 이유는 투수지역의 토양의 특성, 강우조건, 지형적 특징 등이 영향을 미치는 것으로 판단된다.

This study aims to explore alternative strategies for the archival professional training system in response to changing records management environments. It found implications in the training and qualification system for overseas archival professionals and compared and analyzed the qualification system for Korean archival professionals. In addition, by analyzing the archival graduate schools' general status and the instructors' research performance, the study confirmed that many instructors have low academic interest in archival studies and the gap between schools was significant. Based on this, interviews with professors and experts were conducted to gather opinions on improving the archival professional training system. In conclusion, the study presents prerequisite tasks of organizing an archival community governance system and securing self-regulatory power. Moreover, it proposes innovative measures for the archival professional training system with three major tasks: creating graduate education guidelines, establishing a continuing and deepening education system, and transforming educational institutions.

This study aimed to systematically review the literature on the stress reduction of meaning-centered therapy (MCT) studies in Korea and to identify the characteristics of MCT for stress reduction. MCT studies aimed at reducing stress symptoms were searched among peer reviewed journal articles and unpublished dissertations until April, 2020. Two independent researchers assessed the risk of bias and the quality of the report using Scottish Intercollegiate Guidelines Network criteria. As a result of searching with 7 databases, 7 studies were finally selected. Seven MCTs were for all age groups, and 5 studies reported MCT was effective in reducing stress symptoms. Both single and combined type interventions were effective in reducing stress symptom, Researchers used the combined MCT more than single MCT program. The study with no significant effect was related to school test stress. There is a need to develop MCTs suitable for school-age youth with test stress in the future.
