본 연구는 발전소등에서 발생하는 중유회를 재활용한 탈취패널 제조시 활성탄, 규조토등의 첨가제를 활용함으로써 포름알데히드 및 톨루엔에 대한 제거성능을 향상시켜 중유회의 탈취패널 원료로서의 사용가능성을 확인하였다. 단일 첨가제를 사용하여 제작된 중유회 재활용 탈취패널의 경우 포름알데히드에 대해서는 93% 이상, 톨루엔에 대해서는 97% 이상의 제거성능을 보였으나 기준 패널에 비하여 압축강도가 27~63% 감소하였다. 반면에 두 가지 첨가제를 여러 가지 비율로 혼합하여 제조된 것 중 활성탄과 규조토가 5 wt%씩 첨가된 패널은 포름알데히드 84%, 톨루엔 96%의 제거성능을 보였으며 압축 강도는 기준패널보다 32%증가하였다. 따라서 첨가제의 혼합사용을 통하여 중유회재활용 탈취패널을 제조할 경우 유해가스 제거성능과 패널의 강도를 향상 시키는 것이 확인되었다. This study aims to examine the possible use of heavy oil fly ash as raw material for deodorization panels by adding additives such as activated carbon and diatomite during deodorization panel manufacturing process and improving the performance of formaldehyde and toluene elimination. The recycled heavy oil flyash deodorization panel to be used either of them as additives removed more than 93% of formaldehyde and more than 97% of toluen but the compressive strength was decreased 27 to 63%. In an experiment to be used both additives, Whereas, the panel to include activated carbon 5% and diatomite 5% removed 84% against formaldehyde and 96% against toluen, and the compressive strength was increased 32% better than standard panel. Therefore it could be confirmed that the recycled heavy oil flyash deodorization panel is increased the compressive strength and the removal efficiency against harmful chemical substances by using the additives mixture.

A Three-step Proteolytic Cascade Mediates the Activation of the Peptidoglycan-induced Toll Pathway in an Insect

Kim, Chan-Hee,Kim, Su-Jin,Kan, Hongnan,Kwon, Hyun-Mi,Roh, Kyung-Baeg,Jiang, Rui,Yang, Yu,Park, Ji-Won,Lee, Hyeon-Hwa,Ha, Nam-Chul,Kang, Hee Jung,Nonaka, Masaru,Sö,derhä,ll, Kenneth,Lee, Bok Lu American Society for Biochemistry and Molecular Bi 2008 The Journal of biological chemistry Vol.283 No.12

<P>The recognition of lysine-type peptidoglycans (PG) by the PG recognition complex has been suggested to cause activation of the serine protease cascade leading to the processing of Spätzle and subsequent activation of the Toll signaling pathway. So far, two serine proteases involved in the lysine-type PG Toll signaling pathway have been identified. One is a modular serine protease functioning as an initial enzyme to be recruited into the lysine-type PG recognition complex. The other is the Drosophila Spätzle processing enzyme (SPE), a terminal enzyme that converts Spätzle pro-protein to its processed form capable of binding to the Toll receptor. However, it remains unclear how the initial PG recognition signal is transferred to Spätzle resulting in Toll pathway activation. Also, the biochemical characteristics and mechanism of action of a serine protease linking the modular serine protease and SPE have not been investigated. Here, we purified and cloned a novel upstream serine protease of SPE that we named SAE, SPE-activating enzyme, from the hemolymph of a large beetle, Tenebrio molitor larvae. This enzyme was activated by Tenebrio modular serine protease and in turn activated the Tenebrio SPE. The biochemical ordered functions of these three serine proteases were determined in vitro, suggesting that the activation of a three-step proteolytic cascade is necessary and sufficient for lysine-type PG recognition signaling. The processed Spätzle by this cascade induced antibacterial activity in vivo. These results demonstrate that the three-step proteolytic cascade linking the PG recognition complex and Spätzle processing is essential for the PG-dependent Toll signaling pathway.</P>

The Success Factors of Hallyu with focus on K-Pop

( Kenneth Chi Ho Kim ) 한국언어문화학회 2016 한국언어문화 Vol.0 No.60

2016년 한국드라마, “태양의 후예”는 국내에서 시청률 38.8%를 넘었다. 한편 중국에서는 동시에 중국의 아이치이(iQIYI)에서 스트리밍이 되었으며 23억뷰를 기록하였다. 이드라마는 지난 20년간 성장해온 한류의 좋은 사례이기도 하다. 많은 전문가는 한류의 시작이 1997년 중국의 CCTV에 “사랑이 뭐 길래?”가 방송되면서 였다고 한다. 한국드라마에 이어서 K-Pop 또한 한류의 인기를 확대하였다. 초기인 2000년에는 H.O.T가 베이징에서 성공적으로 콘서트를 개최하였다. 슈퍼주니어, 빅뱅과 EXO는 합산하여 소셜네트워크에 팔로워가 1천만 명이 넘는다. 이렇게 성공한 한류는 국내에 문화적으로나 경제적으로 다양한 긍정적인 영향을 미치기도 하였다. 한편 한류, 특히 K-Pop의 성공요인에 대해서는 다양한 연구가 진행되어 왔다. 최근까지 일부 학자들은 분석에 국가 경쟁력을 평가하는 모델을 적용하였고, 다른 학자들은 제작과 소비의 관점 연구를 위해 문화다이아몬드를 선택하였다. 대부분의 연구는 의미 있는 결과를 제시하고 있으나, 추가적으로 외부환경 및 고객 중심의 시장에 대한 이슈를 고려한 연구도 되어야 한다고 판단된다. 본고에서는 온라인 환경과 고객 중심의 시장에 보다 적합하다고 제시된 Kotler의 마케팅 믹스인 4C 모델을 적용하여 K-Pop을 분석하고, 추가적인 외부환경에 대한 요인을 확인하였다. 나아가 글로벌 팬의 이해를 통해 미래의 리저널 전략을 고민하고, 마지막으로 향후의 한류와 K-Pop의 성공을 위해 요구되는 핵심요인들을 제안하였다. In 2016, the Korean drama, “The Descendants of the Sun” reached 38.8% rating in Korea. In China, it was streamed simultaneously on iQIYI and recorded over 2.7 billion views. This drama is a good example of Hallyu, a phenomenon which have been around for 20 years. Many say that Hallyu started when What is Love all about? aired in CCTV in 1997. Following the popularity of Korean Dramas, K-Pop (Korean Pop Music) started to gain recognition. Notably, the boy group H.O.T. performed at sold-out concert in Beijing in February 2000. Super Junior, Big Bang and EXO have over 10 million combined followers in the social network site nowadays. Hallyu had number of positive impacts both culturally and economically on Korea. Reviewing the history of the Hallyu especially K-Pop, the number of success factors were studied. Some scholars used the model to evaluate the national advantage while other scholars used cultural diamond to evaluate production and consumption aspects. All of the studies have legitimate findings, but other aspects including external environment and customer centric market needed to be also taken into consideration. In this article, 4C marketing mix which fits better with online focused environment was used to evaluate K-Pop in customer centric market while number of external issues were reviewed. Further the importance of understanding the global fans was stressed to contemplate about regional strategy moving on. Finally, critical elements for future success of Hallyu and K-Pop were suggested.

Comparing LAI Estimates of Corn and Soybean from Vegetation Indices of Multi-resolution Satellite Images

Kim, Sun-Hwa,Hong, Suk Young,Sudduth, Kenneth A.,Kim, Yihyun,Lee, Kyungdo The Korean Society of Remote Sensing 2012 大韓遠隔探査學會誌 Vol.28 No.6

Leaf area index (LAI) is important in explaining the ability of the crop to intercept solar energy for biomass production and in understanding the impact of crop management practices. This paper describes a procedure for estimating LAI as a function of image-derived vegetation indices from temporal series of IKONOS, Landsat TM, and MODIS satellite images using empirical models and demonstrates its use with data collected at Missouri field sites. LAI data were obtained several times during the 2002 growing season at monitoring sites established in two central Missouri experimental fields, one planted to soybean (Glycine max L.) and the other planted to corn (Zea mays L.). Satellite images at varying spatial and spectral resolutions were acquired and the data were extracted to calculate normalized difference vegetation index (NDVI) after geometric and atmospheric correction. Linear, exponential, and expolinear models were developed to relate temporal NDVI to measured LAI data. Models using IKONOS NDVI estimated LAI of both soybean and corn better than those using Landsat TM or MODIS NDVI. Expolinear models provided more accurate results than linear or exponential models.

The Impact of Blockchain Technology on the Music Industry

Kim, Kenneth Chi Ho The Institute of Internet 2019 Journal of Advanced Smart Convergence Vol.8 No.1

We have reviewed the potential impact of blockchain technology on the music industry by analyzing the views of academia and the industry experts. The music industry had rapid changes from the physical market to the digital market in the past decades. The consumers download and stream music online and mobile during the digital dominant market. While streaming music has been recently growing at a fast rate, fair distribution of revenue to the artists continues to be an issue. Some industry experts believe that the issue of fair distribution of revenue to the artist may be resolved using blockchain technology, while some are skeptical about the application or the duration of impact. The blockchain may enhance speedier payment using smart contracts, provide additional revenue and promote the music if excellent fan support is achieved. The positive impact on the music industry may only be possible if there are detailed consideration of the industry and careful understanding of the customers.

MCN 사업의 현황과 과제

김치호(Kim, Kenneth Chi Ho) 인문콘텐츠학회 2016 인문콘텐츠 Vol.0 No.40

최근 TV 시청 대신 PC 및 스마트 기기를 통한 동영상 시청이 일반화되며 개인 창작자, 즉 크리에이터의 콘텐츠가 확산되고 이에 따라 크리에이터의 콘텐츠 제작 및 유통을 사업화 시키는 데 도움 주는 MCN(Multichannel Network) 사업이 부각되고 있다. MCN은 크리에이터의 콘텐츠 기획, 제작, 마케팅, 저작권, 유통 및 사업의 전반적 또는 일부를 제공하는 사업자로서 크리에이터가 창출하는 수익의 일부를 분배 받는 방식으로 매출을 올리고 있다. 미국에서는 2013년 Dreamworks Animation(드림웍스)가 MCN 기업인 Awesomeness TV를 3천3백만 달러, 2014년 Disney(디즈니)가 Maker Studios를 5억 달러에 인수하면서 해당 사업이 더욱 주목 받게 되었다. 국내에서는 CJ E&M이 가장 먼저 MCN 사업을 시작하였고, DIA TV라는 이름으로 650여개의 채널을 운영하고 있다. 독립 MCN 사업자로서 Treasure Hunter(트레져헌터)는 157억원의 투자를 유치하고 크리에이터들과 MCN사업을 온라인과 오프라인에서 추진하고 있다. 그리고 이러한 MCN에서 활동 중인 일부 크리에이터들은 연간 5억원 이상의 수익을 올리기도 한다. 하지만 YouTube(유튜브)의 성장과 발생하게 된 MCN 사업은 사업구조 상 한계점을 가지고 있고, 극복해야할 과제를 지니고 있다. 가장 큰 과제는 수익성의 확보라고 할 수 있다. 수익성의 확보는 매출 배분율 및 사업 다각화가 핵심이라고 할 수 있는데, 본고에서는 과제의 해결을 CPND(Content, Platform, Network, Device) 관점에서 살펴보고자 한다. 과제의 해결은 MCN이 산업화 되는 과정에 미래의 방향을 제시할 것으로 예상한다. 더불어 아직까지 MCN 사업관련하여 정보 및 연구가 제한적인 현재 시점에서 연구된 정보는 산업의 발전을 도모하고 추후 다양하고 세밀한 연구의 기본적인 토대가 될 것이라 기대한다. With the trend of watching content through computers and smart devices rather than televisions, needs for individual contents have increased. MCN(Multichannel Network) is a business of servicing the creators and the business support creators in all or some of the services such as content planning, production, marketing, intellectual property management, and distribution. The creators would share the advertising revenue shared by YouTube with MCNs. MCN started to gain greater recognition when Dreamworks Animations acquired Awesomeness TV for $300 million in 2013 and Disney acquired Maker Studios for $500 million in 2014. In Korea, CJ E&M started MCN business under DIA TV name and currently operate over 650 channels. Independent MCN operator, Treasure Hunter was funded over 157 billion KRW and run business both online and offline. Some of the creators make over 5 billion KRW annually. But MCN business has its challenges and one of the challenge is its profitability. The profitability issue can be overcome by re-examining the revenue split ratios and business diversification. From this study, the examination will be view using CPND(Content, Platform, Network, Device) value chain, Hopefully the raised issues and the examinations will support the industry development in the future. With limited number of the resources given that the industry is rather young, studied information will not only benefit the industry at the moment, but also future studies by the researchers.
