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.

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.

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

<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 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.

Advertising versus Sales Promotion: An Examination of the Japanese Food Industry, 1976-2008

Changju Kim,Yingzi Xu,Kenneth F. Hyde 한국마케팅과학회 2011 마케팅과학연구 Vol.21 No.4

The issue of increasing sales promotion at the expense of advertising has been examined with growing concern over the last two decades. This study provides an exploratory analysis of the issues of allocation of marketing communication budget in the Japanese food industry: advertising for the long-term versus sales promotion for the short-term. Based on data collected from Nikkei Need-FinancialQUEST (Nikkei Digital Media, 2011), an increase in marketing budget allocated to sales promotion relative to advertising was observed in a time series analysis study from 1976 to 2008. The use of sales promotion budget has a two-fold effect on financial performance: the sales promotion budget is positively related to sales volumes and negatively related to profitability. Managerial implications of these findings and areas for future research are discussed. Research shows the weakened power of traditional advertising in a diversified media environment; the growth rate differential of sales promotion relative to advertising has become noticeable in recent years (Kim, 2010; Li, Lee, Lee, and Griffin, 2011). However, in spite of qualitative and quantitative research in the last two decades, there is a gap concerning the outcomes of advertising and sales promotion budget allocation decisions in the industrial sector. The aim of this article is to give a better understanding of whether the paradigm shift in budget allocation from advertising to sales promotion exists, and if this is the case, how marketing firms’ financial performance is affected in regards to sales volume and profitability. To address these issues, this study examines the budget allocation decisions for advertising and sales promotion from the perspective of short-term versus long-term objectives (Quelch, 1983; Achenbaum and Mitchel, 1987; Buzzell, Quelch, and Salmon, 1990; Jones, 1990; Low and Mohr, 1999, 2000; Rossiter and Percy, 1997). The issue of increasing sales promotion at the expense of advertising has been viewed with growing concern by both practitioners and academics over the last two decades. In this context, considerable attention has been paid to the fundamental changes in the advertising-to-sales promotion ratio (Quelch, 1983; Johnson, 1988; Buzzell, Quelch and Salmon, 1990; Messinger and Narasimhan, 1995; Ailawadi, 2001). Partly as a result of the growing buying power of retailers, manufacturers have been reducing their commitment to advertising activities and spending much more on trade promotion and consumer promotion. The rapid growth in the relative proportion of trade promotion compared to total sales promotion is remarkable. This study seeks to identify the changes in the relative emphasis on communication strategy at the industry level in Japan over an extended period of time. Therefore, we propose:H1: The proportion of the marketing communications budget allocated to sales promotion, versus advertising, has increased in Japan. H2: The proportion of the marketing communications budget allocated to sales promotion increased sharply around the time of the collapse of the bubble economy in 1991. In regard to consumer package goods manufacturers, the growth rate of sales volume may be lower than of the growth rate for sales promotion (Teramoto, 2001). This is not surprising due to the saturated market in Japan. A short-term perspective is defined as the degree to which management emphasizes short-term objectives and tasks, generally one year or less, and thus encourages short-term results (Burke, 1984; Rossiter and Percy, 1997). The short-term results of a sales promotion strategy are illustrated in an increase in sales volume. Yet the effect of sales promotions on sales volume does not last particularly long. This is because the carry-over effects of sales promotions are relatively low, compared with the level of purchase during the promotion period (Cotton and Babb, 1978). Often a company using sales promotion aggressively has a difficult time selli...
