  • Generally, inaccurate reports on environmental issues occur due to various factors. The purpose of this study was to find out a way to enhance accuracy of environmental reporting. So the reporters' career and college major had been compared to the accuracy of their articles. The by-lined environmental articles in nine dailies published in 1991 were checked. Results of this study were as follows. (I) Inaccuracy rate in environmental articles was 54.2%. Inaccuracies appeared 1.7 times per an article, while the average frequency of inaccuracies in overall articles was 0.9 time. (2) Errors in the articles consist of 65.8% of subjective inaccuracies and 34.2% of subjective inaccuracies. They derive from the false usage of terminology(15.8% ),misquotation(14.5%), incorrect statistics(13%), exaggeration(13%), inaccurate title(7.9%), and false comparison(5%). (3) Inaccuracy rate by the type of articles was 66.7% in columns, 60% in feature stories, 54.5% in-depth stories, 40.9% in straight news, respectively. (4) Inaccuracy rate by the specific field was shown 71.4% in environmental impacts assessment, 52.5% in water pollution, 37.5% in waste management, and 35.7% in air pollution. (5) According to the result of chi-square test analysis, there were no statistically significant differences of inaccuracy rate and of subjective, and objective inaccuracies relevant to the period of reporters' career covering environmental reporting and the nature of articles, and college major.

  • 불확정 요소가 많은 건설 프로젝트에서 코스트 리스크의 분석은 관련 전문가의 통찰력이나 주관적 판단에 의존하는 경우가 많다. 하지만 국내 건설산업의 경우 코스트 리스크 분석시 객관적인 산출근거에 의한 확률만을 고려 할 뿐 계량적 측정이 어려운 주관적 요소를 합리 적으로 반영하기 위한 방법이나 절차를 갖고 있지 못하다. 이와 같은 관점에서 본 연구는 보다 신뢰성이 우수한 비용견적을 위해서 전문가의 주관적인 요소까지 종합적으로 평가하고, 리스크로 인한 비용의 변동을 정량적으로 분석할 수 있는 새로운 로스트 리스크 분석모델을 제시하였다 아울러 실무에서도 간단한 절차에 따라 모델을 체계적으로 수행할 수 있도록 편리한 사용자 인터페이스를 제공해 주는 프로토타입을 구현하였다.

시각에 의한 식이 섭취 모니터링의 부정확성이 김밥 섭취량과 포만도에 미치는 영향 (The Effect of the Consumption Monitoring Inaccuracy by Vision on Kimbab Intake and Satiety Rate)

  • It was examined whether altering vision would influence food intake through consumption monitoring and whether this would be reflected in consumption estimate and satiety. The experiment was designed in two visibility levels: 1) an accurate visual cue (bowl covered with wrap) vs 2) a biased visual cue (bowl covered with foil). Thirty three female college students participated in this study. The subjects ate Kimbab in the lab once a week for 2 weeks. They were served 24 pieces of Kimbab in a bowl covered either with wrap or foil. The results showed that the actual Kimbab intake from the bowl covered with foil was significantly lower than the test using wrap ($13.4{\pm}3.3$ pieces vs $15.0{\pm}3.8$ pieces, p < 0.05). And there were no significant differences from the cognitive Kimbab intake between the tests with foil and wrap. However, the satiety rate of Kimbab in a bowl covered with foil was significantly higher than that with wrap at 1 hour and 2 hour after the Kimbab eaten (p < 0.05). Less consumed cases were recognized by subjects due to the inaccuracy during the consumption monitoring process. This result revealed that vision influences not only eating behavior but also subjective feelings of satiety after meal. In conclusion, the consumption monitoring by visual cues can play an important role in food intake and satiety rate.

  • The purpose of this study is to evaluate the walking behavior analysis methodology used in the previous studies, paying attention to the demand for empirical data collecting for urban and neighborhood planning. The preceding researches are divided into (1)Recording, (2) Surveys, (3)Statistical data, (4)Global positioning system (GPS) devices, and (5)Mobile Big Data analysis. Next, we analyze the precedent research and identify the changes of the walkability research. (1)being required empirical data on the actual walking and moving patterns of people, (2)beginning to be measured micro-walking behaviors such as actual route, walking facilities, detour, walking area. In addition, according to the trend of research, it is analyzed that the use of GPS device and the mobile big data are newly emerged. Finally, we analyze pedestrian data based on mobile big data in terms of 'application' and distinguishing it from existing survey methodology. We present the possibility of mobile big data. (1)Improvement of human, temporal and spatial constraints of data collection, (2)Improvement of inaccuracy of collected data, (3)Improvement of subjective intervention in data collection and preprocessing, (4)Expandability of walking environment research.
