With the development of the Internet, the media market is experiencing rapid change. The traditional form of offline newspaper markets, which has created the mainstream news delivery market, have been losing large amounts of power due to the emergence of online media. On the other hand, online media armed with its ability to post breaking news almost as it occurs has increased its influence and popularity at a rapid speed. However, since the exposure time and readership of online newspapers are less than their offline counterparts online media has a high dependence on sensational titles and somewhat exaggerating headlines rather than the objective and recapitulative headlines which are preferred. This paper will examine the function and significance of headlines, and conduct a comparative analysis on contents and forms of the headlines in offline newspaper and online newspaper in order to identify the characteristics of each newspaper. Through comparisons, it examines the types of headlines and the transference of headlines. In addition, it examines the differences in recognition of copy editors according to media in determining the headline, and it illuminates which type of headlines is preferred in order to instigate readers to read online newspapers. The analysis results of title-transferring cases in offline newspaper and online newspapers are that offline newspapers try to convey the contents accurately by making use of an information-transferring headline, while attention-attracting headline or subject-hiding headlines tend to be used for attracting the eye of readers. In addition, analysis results of headlines that are put on the top with a click counts in online newspapers are that attention-attracting headlines are the majority, while subject-hiding headlines that are hardly used in offline newspapers, are well-used in online newspapers. In an interview with copy editors, they responded that offline editors focus on the fact-transference in determining the title, while online editors put the weight on immediacy in the delivery of news and the function of guiding readers.

우리나라는 6월부터 9월까지의 우기에 강우가 집중 발생하는 기상특성으로 인해 자연재해의 95% 이상이 집중호우와 태풍에 의한 풍수해로 집계되고 있을 만큼 홍수피해에 취약하며, 오래전부터 홍수방어에 대한 구조적 대책이 시행되어왔다. 본 연구의 목적은 의사결정기법중의 하나인 의사결정나무를 이용하여 유역내 홍수방어를 위한 기본적인 후보대안을 제시하는데 있다. 이러한 후보대안은 유역이 가지고 있는 치수적 기능을 최대한 살리고 상ㆍ하류의 유기적인 홍수방어기능을 효율적으로 증대시키는 다수의 조합으로 제시되었다. 또한 본 연구에서는 유역종합치수계획 수립시 적용가능한 홍수방어 대안 조합 지침을 제시하였다. Intensive rainfalls in wet season (June-September) result in serious flood damage which is about 95% of natural hazard in Korea. Recently, in order to cope with repeated flood hazard, comprehensive flood control plans have been carried out in large basins in Korea. The plans suggest structural alternative plans for flood mitigation as well as non-structural plans. In this study, a practical method using a decision tree was developed to systematically allocate structural facilities for flood control, which maximizes the flood control capacity in a basin. This study also presents a practical guidance to organize structural defensive alternatives for a comprehensive flood control plan in a large basin.
