The area of paddy fields for upland crop cultivation is gradually increasing. In this context, we developed a chain type mole drainer that can be attached to a tractor to prevent the wet injury of crops. To conduct a field test, we formed underdrains at 2 m intervals in a paddy field wherein soybeans are cultivated, and we investigated the status of the soil moisture, groundwater level, and soybean growth during the cultivation period. The soil moisture content decreased by 22.3~26.8% in the test plot and by 5.9~6.9% in the control plot during a period of 57~88 hour after a rainfall of 41.5~157.0 mm. The effect of underdrainage was clear as the hourly groundwater level decreased approximately 2.8 times faster in the test plot compared with the control plot. Moreover, the soybean yield was greater by 78.6 kg/10a in the test plot than in the control plot. Therefore, for soybean cultivation in paddy fields, the use of the developed mole drainer is expected to help in improving the drainage and increasing the soybean yield.

Soil microbes are widely well known to play an important role for sustainable agriculture in terms of crop healthy cultivation and environmental conservation. In this context, the distributional characteristics of soil microbes according to cropping systems were investigated under rice (R)-rice (R), rice (R)-barley (B)-rice (R), and soybean (S)-barley (B)-soybean (S) cropping condition to get basic informations for sustainable agriculture, where barley was grown for winter, in mid-mountainous loam paddy located at the altitude of 285 m above sea level in Sangju area from 2014 to 2015. Estimating from microbial communities by fatty acid methyl ester (FAME) method, a total biomass of bacteria, actinomycetes, and fungi in R-B-R plot was 37% and 40% higher than that in S-B-S and R-R plots, respectively (p < 0.05). In especial, bacteria and fungi were more in R-B-R plot than those in any other ones. B. japonicum, AMF, and mesophilic Bacillus sp. were also greater in S-B-S plot than those. In the community distribution, however, bacteria and actinomycetes showed comparatively high values in S-B-S plot relative to either R-R or R-B-R plot including rice, in which fungi outstanding. In the correlation between microbial biomass and soil properties changed by the cropping, bacteria was positively correlated with C:N ratio; actinomycetes with exchangeable Ca; fungi with available $P_2O_5$ (p < 0.05). While these microbes showed negative response to water stable aggregates of soil.

이 연구는 스토리텔링 기획·분석을 위한 '플롯적층' 방법론을 제안하는 데 목적을 둔다. 일정한 서사분량을 가진 스토리콘텐츠라면 비중을 갖고 등장하는 인물들이 여러 명일 수 있다. 그들 대다수는 스토리의 맥락에 유의미한 영향력을 행사하며 선택과 실천으로 참여한다. 역동적으로 변화해가면서 새로운 관계망을 구축·탈구축해간다. 플롯적층 방법론은 주인공이 이끄는 메인플롯을 근간에 두고, 주요 인물들이 대타적 성격을 내보이며 주체적인 서브플롯의 형성에 기여한다는 사실에 주목해 그 과정을 '전략' 차원에서 살펴보려는 시도의 결과다. 서사물 속 주요 인물들은 개성적·주체적 삶을 살아가는 것과 무관하게 메인플롯의 구심력 안에서 상대적인 지위를 가진다. 그들의 여정은 메인플롯의 '인과적 설득' 과정을 연장·강조·분담하면서 각각 정서적 공감(파토스), 도덕적·윤리적 입장(에토스), 이성적 논리(로고스)의 기능으로 개성화되는 경향이 있다. 이처럼 주요 인물들의 서브플롯은 세가지 기능적 특성에 따라 적층되는 바, 주변인물들의 수효와 역할에 따라 2차, 3차 적층구조로 중층화될 수도 있다. 후속 연구를 통해 플롯적층 방법론이 더 세공된다면 서브플롯이 메인 플롯과 접합/분기되는 과정에 대한 전략적 설계(기획)와 심미적 비평(분석)의 가능성이 열릴 것이다.

In the context of exploring how Artificial Intelligence(AI) can revolutionize the entertainment industry, more and more film and television productions have begun to try to intervene AI technology in various aspects of content creation. However, despite the fact that AI can generate a large amount of textual content and dynamic visual effects, it still faces challenges in terms of plot expression and delivery. This thesis explores the strengths and weaknesses, innovations, and future developments of AI technology in plot production by analyzing existing film and television productions and production practices generated using AI technology. The study proves that as AI technology continues to improve, its use in short-form production will become more and more prevalent in the future, helping human creators become more efficient and even able to produce Short Dramas in full flow.

포스트 모던 시대의 내러티브는 고전적인 일방향 소통방식에 비해 작가와 수용자의 관계를 특별하게 변화시켰다. 이러한 스토리텔링에서는 수용자가 플롯에 직접 관여하여 내러티브를 변화시킬 수 있는 형식에 대한 논의가 있어왔다. 그러나, 이런 연구들은 일방향적 내러티브 분석에 적용되기에는 어려움이 있다. 이런 가운데 <지구를 지컥라>는 영화의 매체적 특성을 유지하면서도 수용자의 역할을 강조하는 내러티브를 활용하고 있다. <지구를 지켜라>의 내러티브는 관객들에게 다성적으로 읽힌다. 관객들은 영화가 제공하는 서로 다른 목소리를 통해서 표면적인 이야기 외에 스스로가 재구성한 또 하나의 이야기를 만들어 내도록 유도 받는다. 이 글에서는 <지구를 지켜라>의 내러티브를 구성하는 요소들이 어떻게 관객들에게 새로운 이야기를 구성해내도록 하는지 살펴보면서, 두 가지 이야기의 상호작용 속에서 구축된 내러티브를 살펴보고자 한다.

Purpose - This study investigates research trends by searching for English keywords and abstracts in 1,511 Korean journal articles in the Korea Citation Index from the 2002-2019 period using the term "Port." The study aims to lay the foundation for a more balanced development of port research. Design/methodology - Using abstract and keyword data, we perform frequency analysis and word embedding (Word2vec). A t-SNE plot shows the main keywords extracted using the TextRank algorithm. To analyze which words were used in what context in our two nine-year subperiods (2002-2010 and 2010-2019), we use Scattertext and scaled F-scores. Findings - First, during the 18-year study period, port research has developed through the convergence of diverse academic fields, covering 102 subject areas and 219 journals. Second, our frequency analysis of 4,431 keywords in 1,511 papers shows that the words "Port" (60 times), "Port Competitiveness" (33 times), and "Port Authority" (29 times), among others, are attractive to most researchers. Third, a word embedding analysis identifies the words highly correlated with the top eight keywords and visually shows four different subject clusters in a t-SNE plot. Fourth, we use Scattertext to compare words used in the two research sub-periods. Originality/value - This study is the first to apply abstract and keyword analysis and various text mining techniques to Korean journal articles in port research and thus has important implications. Further in-depth studies should collect a greater variety of textual data and analyze and compare port studies from different countries.

In this paper, we analyze the calendaring operation in the process of paper manufacturing. Controllable parameters involved in the calendaring operation are the calendar material, temperature and pressure. Main objective of this paper is to find the robust design of these parameters which would provide consistent quality of paper in terms of the thickness, brightness, and roughness. We first use a split-plot design in the context of a central composit design for a preliminary analysis to find the proper calendar material. Next, response surfaces for the mean and variance of each quality attribute are fitted as functions of calender temperature and pressure. Bootstrap resampling approach is used to find the robust parameter design.

This study examined the storytelling characteristics of the super-compressed web drama "72 seconds". By analyzing all seasonal episodes of "72 seconds" and applying the various storytelling methodologies and related theories, this paper derived the main storytelling characteristics of "72 seconds" as follows. First, through the composition of the microscopic non-plot, the story value of empathy and fun is maximized, even though there is no dramatic composition compared to the general movie or drama. Second, by the specialization of everyday life, it leads to the transition from everyday experience to the new context. In other words, it provides a consensus through the cognitive expansion and interest by unfamiliarity of the ordinary experience to the audience. Third, based on the characteristics of super-compression and short theme, it utilizes fully stylistic narration like rapping. This makes the audience feel novel and further enhances the branding effect of content. And finally, based on various hybridity and variation, it uses remediation actively in all respects, especially comedy genre and comic factor.

Similar to regression, many measures to detect influential data points in discriminant analysis have been developed. Many follow similar principles as the diagnostic measures used in linear regression in the context of discriminant analysis. Here we focus on the impact on the predicted classification posterior probability when a data point is omitted. The new method is intuitive and easily interpretable compared to existing methods. We also propose a graphical display to show the individual movement of the posterior probability of other data points when a specific data point is omitted. This enables the summaries to capture the overall pattern of the change.

Although the importance of developing reliable and systematic GHG inventory has increased, the GIS/RS-based national scale LULUCF (Land Use, Land-Use Change and Forestry) sector analysis is insufficient in the context of the Paris Agreement. In this study, the change in $CO_2$ storage of forest land due to land use change is estimated using two GIS/RS methodologies, Sampling and Wall-to-Wall methods, from 2000 to 2010. Particularly, various imagery with sampling data and land cover maps are used for Sampling and Wall-to-Wall methods, respectively. This land use matrix of these methodologies and the national cadastral statistics are classified by six land-use categories (Forest land, Cropland, Grassland, Wetlands, Settlements, and Other land). The difference of area between the result of Sampling methods and the cadastral statistics decreases as the sample plot distance decreases. However, the difference is not significant under a 2 km sample plot. In the 2000s, the Wall-to-Wall method showed similar results to sampling under a 2 km distance except for the Settlement category. With the Wall-to-Wall method, $CO_2$ storage is higher than that of the Sampling method. Accordingly, the Wall-to-Wall method would be more advantageous than the Sampling method in the presence of sufficient spatial data for GHG inventory assessment. These results can contribute to establish an annual report system of national greenhouse gas inventory in the LULUCF sector.
