최근 유튜브의 성장이 주목받고 있다. 유튜브는 콘텐츠를 소비하는 채널일 뿐만 아니라 소비자의 의사를 표시하는 공간이 되고 있다. 소비자들은 댓글이라는 형식으로 유튜브 안에서 그들의 의견을 표출한다. 이 연구는 유튜브에 업로드되어 시청되는 글로벌 기업가 연설문과 영상을 시청하고 작성한 댓글의 텍스트를 연구대상으로 한다. 텍스트 마이닝 소프트웨어인 Leximancer를 사용하여 각각의 연설문과 댓글을 대상으로 내용 분석(content analysis)을 시행하였다. 각 기업가 연설문의 주제는 대응분석(correspondence analysis)을 사용하여 분석하였고 기업가 개인의 성향과 특성과 관련 있는 주제를 도출하였다. 댓글에서는 각 연설문의 내용과는 관계없이 공통적으로 money, work, need의 주제를 발견하였다. 텍스트의 길이가 다름을 고려하여 추가로 중요도 지표 (Prominence Index) 분석을 실행하였고 연설문 내용과 시청자 댓글의 공통적인 주제를 구성하는 핵심어로 time, future, better, best, change, life, business, need를 도출하였다. 유튜브 연설문의 시청자는 인생과 시간, 미래, 고객의 니즈, 긍정적 변화에 대한 메시지에 대하여 동일한 주제로 반응하는 것으로 나타났다.

I have briefly described some of the important advances in hydrosystems and to remark on the important scientific research priorities in hydrological sciences. We have concentrated on data collection systems, real-time control of hydrosystems, global climate change and decision support systems and GIS. In summary, I would like to stress the following points: - the advances in data collection systems, advanced methodologies for interfacion hydrologic, hydraulic, and optimization models through optimal control approaches; and the advances in decision support systems and GIS will allow the interfacing of all these technologies into some sophisticated and much needed tools for operating hydrosystems; - the ability to better understand the hydrologic processes and their relationships to other earth processes is important to understanding and modelling of the hydrologic cycle and its interactions with the ocean-atmosphere system; - and the solution to a better understanding of hydrologic sciences needs to be an international effort such as the GEWEX program briefly discussed above. I would like to thamk each of you for listening to my lecture and to once again thank those responsible for me being here today. Thank you.

Video platforms, including YouTube, have a structure in which the number of video views is directly related to the publisher's profits. Therefore, video publishers induce viewers by using provocative titles and thumbnails to garner more views. The conventional technique used to limit such harmful videos has low detection accuracy and relies on follow-up measures based on user reports. To address these problems, this study proposes a technique to improve the accuracy of filtering harmful media using thumbnails, titles, and audio data from videos. This study analyzed these three pieces of multimodal information; if the number of harmful determinations was greater than the set threshold, the video was deemed to be harmful, and its upload was restricted. The experimental results showed that the proposed multimodal information extraction technique used for harmfulvideo filtering achieved a 9% better performance than YouTube's Restricted Mode with regard to detection accuracy and a 41% better performance than the YouTube automation system.

콘텐츠 소비 환경의 변화는 기업들이 마케팅 플랫폼으로서 소셜미디어의 가능성을 인지하게끔 하였다. 이와 함께 마케팅 '콘텐츠'의 중요성이 두드러짐에 따라 기업에만 의미가 있는 광고가 아닌 소비자에게도 가치 있는 콘텐츠를 창출하는 '콘텐츠 마케팅(Content Marketing)'이 떠오르고 있다. 이를 위해 기업들은 유튜브에 브랜드 채널을 개설해 채널에서만 접할 수 있는 유의미한 콘텐츠를 제공할 뿐만 아니라 유튜브 크리에이터와 콘텐츠 협업을 진행하는 등 유튜브를 기반으로 다양한 콘텐츠 마케팅 활동을 진행하고 있다. 본 논문은 콘텐츠 마케팅을 실천하고 있는 대표적 기업들인 국내 로드숍 화장품 브랜드가 유튜브를 어떻게 활용하고 있는지 파악하고 콘텐츠 디자인의 방향성을 제안하는 데 목적이 있다. 이를 위해 에뛰드, 이니스프리, 미샤, 더페이스샵 4개의 브랜드별 유튜브 마케팅 콘텐츠 사례를 살펴보고 그 유형을 구분 및 분석하였다. 그 결과 유튜브 브랜드 채널에 안정된 구독자 수가 없으면 뷰티 크리에이터와 콘텐츠 협업을 진행하는 것이 효과적일 수 있다는 것을 알 수 있었다. 또한, 콘텐츠 목적을 분명히 하는 것과 콘텐츠 전달 방식의 차별화가 중요하다는 결론을 도출할 수 있었다.

Carbon fibers are a new breed of high-strength materials. The existence of carbon fiber came into being in 1879 when Edison took out a patent for the manufacture of carbon filaments suitable for use in electric lamps. However, it was in the early 1960s when successful commercial production was started, as the requirements of the aerospace industry for better and lightweight materials became of paramount importance. In recent decades, carbon fibers have found wide applications in commercial and civilian aircraft, along with recreational, industrial, and transportation markets as the price of carbon fiber has come down and technologies have matured. The market for carbon fiber has experienced a good growth in recent years. The growth rate for the last 23years was about 12%. The article reviewed 9,641 Korea, U.S., Japan, Europe patents issued in the carbon fibers in order to offer additional insight for researchers and companies seeking to navigate carbon fiber patent landscape. This article will provide you with all the valuable information and tools you will need to investigate your study successfully within the carbon fiber field. This article also will save you hundreds of hours of your own personal research time and will significantly benefit you in expanding your business in the carbon fiber market.

The aim of this article is to argue that BanLyeo music (companion music) is much better than medicine. A companion who shares thoughts or actions, or a metaphorical description of an object that is always close or carried. Isn't the music that we share in our daily lives a BanLyeo music (companion music)? Music stays with us forever as long as we choose. Therefore, it is music that can go with us until the end, so I think we should call it BanLyeo music (companion music). Music can be with us whenever and wherever we want, soothing sadness and pain and cheering us up. Here is a person who is living a second life happily because of BanLyeo music. Beyond the passive listening to music, direct and active music performance is a great power to save one person. As a more effective healing agent than medicine, BanLyeo music is a great power to stay together for the rest of your life and cheer you up. So, I think music is much better than medicine.

This paper proposes an improved implementation algorithm for the continuous-time receding horizon control (RHC). The proposed algorithm has a feature that it has better control performance than the existing algorithm. Main idea of the proposed algorithm is that we can approximate the original RHC problem better by assuming the predicted input trajectory on the prediction horizon has a continuous form, which is constructed from linear interpolation of finite number of vectors. This, in turn, leads to improved control performance. We derive a predictor such that it takes linear interpolation into account and proposes the method by which we can express the cost exactly. Through simulation study fur an inverted pendulum, we illustrate that the proposed algorithm has the better control performance than the existing one.

A study was made on the radioiodination of organic compounds in presence of hydrogen peroxide both in aqueous and organic solvent systems. In case of the reaction of rosebengal, Hippuran, and 5-iodo-uracil the aqueous reaction system could give high labelling yield within a relatively short reaction time. Labelling yield of average 50% could be obtained within 30 minutes of reaction sequence. In cases of organic solvent systems (D.M.S.O., D.M.F., and Dioxane) the solvent system of D.M.S.O. could give better yield for neutral organic compounds, where as D.M.F. and Dioxane gave better labelling result for acidic materials. Especially, o-iodobenzoic acid, o-iodotoluene, and pentachlorophenol could be labelled better in organic solvent system.
