This study examines the fact-check coverage provided by the SNU fact-check center site(factcheck.snu.ac.kr). A total of 50 articles that were cross-checked by multiple news media organizations were analyzed. The study's variables were topics, types, characteristics, consistency of the news media organizations' judgement, and fact-check sources. This study found that fact-checking coverage was generally focused on presidential or general election candidates or politicians, as well as political topics. The types of fact-checking coverage primarily included factual information, as well as some opinions or interpretations. Fact-check coverage was mainly focused on the facts of the statements themselves, causal relationships, or the timing or target of the comparison criteria. On average, the fact-checking coverage most frequently assigned the judgment 'mostly false, and primarily used interviews of individuals or data from organizations involved in the issue, government data, and experts' statements as the bases for its fact-checking judgements.

Considering about construction projects characteristics, there Is an existing uncertainty which causes inaccuracy or invalidity under decision making situation. Therefore, cost risk analysis of numerous construction projects are Inclined to depend on expert's experiences and subjective judgements. In Korean domestic construction works, however, there is no reasonable method or process for applying subjective elements. Only probabilistic analysis using objective calculation are being used now. This research suggests a cost risk analysis method to analyze quantitatively Cost Impact by risk, and it appraises expert's subjective elements for the purpose of enhancing validity of cost estimation. Moreover, a new cost risk analysis method is introduced for providing convenient user interface in practical business.

Park, Keun-Hye government has just established a new ministry for integrating and managing the policies for science & technology and ICT. From the ICT governance perspective, the new ministry implies separating promotion policies from regulation polices. The current paper aims to present ICT policy implications by providing a perspective on regulation and promotion. A delphi survey was conducted for 32 experts in ICT sector. According to the experts, a clear distinction between regulation and promotion policies is difficult, and thus, integrating regulation and promotion policies looks more preferable. In general, an independent ministry that integrates regulation and promotion policies is mostly preferred. Some suggested an independent committee inside the ministry might be desirable, especially for the broadcasting regulation policy to be independent from the ministry control. The current study proposes tight collaboration between the newly established ICT ministry and the Korea Communications Commission, and in the long term, integrated administration of promotion and regulation policies. In particular, this study emphasizes the importance of the integrated policy management to enhance government policy capacity.
