  • Since late 2016, protectionism has been a major trend in world trade with the Great Britain exiting the European Union and the United States electing Donald Trump as the 45th president. Consequently, there has been a huge public outcry regarding the negative prospects of heavy industry firms in Korea, which are highly dependent upon international trade with Western countries including the United States. In light of such trend and concerns, we have tried to predict business performance of heavy industry firms in Korea with data regarding trade policy of the United States. United States International Trade Commission (USITC) levies countervailing duties and anti-dumping duties to firms that violate its fair-trade regulations. In this study, we have performed data analysis with past records of countervailing duties and anti-dumping duties. With results from clustering analysis, it could be concluded that trade policy trends of the Unites States significantly affects the business performance of heavy industry firms in Korea. Furthermore, we have attempted to quantify such effects by employing long short-term memory (LSTM), a popular neural networks model that is well-suited to deal with sequential data. Our major contribution is that we have succeeded in empirically validating the intuitive argument and also predicting the future trend with rigorous data mining techniques. With some improvements, our results are expected to be highly relevant to designing regulations regarding heavy industry in Korea.

  • The geochemical partitioning of arsenic in contaminated soils from a of wet land and tailing of the abandoned mine is examined. Chemical analysis and sequential extraction method by ultrasound-sonication extraction are applied to investigate the mobility and chemical existence conditions of arsenic as well as heavy metals. The results of this study showed that heavy metals concentration of tailings showed as a following order: Fe > As > Cu > Pb > Cr. The highest metal concentration was recognized in samples less than $63\;{\mu}m$ fraction in their particle sizes. Exchangeable and carbonate fractions in soil samples showed following Cu > As > Pb > Fe > Cr for tailings, and Fe > Pb > Cu > As > Cr for reservoir soils, respectively. Arsenic was bound as exchangeable fraction in tailings and its concentration appeared higher than those of the other metals. Thus, As can be easily dispersed into soil and water environments. The obtained results can be used to design soil remediation plan in the study area and require further detailed study to investigate severe environmental pollution of surface water as well as rivers with respect to heavy metals in terms of speciation analysis of toxic elements such as As and Cr.

  • Damage level of coastal structures has been scaled up according to increase of wave height and duration of the storm due to the abnormal global climate change. So, the design criteria for new breakwaters is being intensified and structural strengthening is also conducted for the existing breakwaters. Recently, interlocking concept has been much attention to enhance the structural stability of the conventional caisson structure designed individually to resist waves. The interlocking caisson breakwater may be survival even if unusual high wave occurs because the maximum wave force may be reduced by phase lags among the wave forces acting on each caisson. In this study, the dispersion characteristics of wave forces using interlocking system that connect the upper part of caisson with cable in the normal direction of breakwater was investigated. A simplified linear model was developed for computational efficiency, in which the foundation and connection cables were modelled as linear springs, and caisson structures were assumed to be rigid. From numerical experiments, it can be found that the higher wave forces are transmitted through the cable as the angle of incident wave is larger, and the larger the stiffness of the interlocking cable makes larger wave dispersion effect.

  • Visualization of documents will help users when they do search similar documents. and all research in information retrieval addresses itself to the problem of a user with an information need facing a data source containing an acceptable solution to that need. In various contexts. adequate solutions to this problem have included alphabetized cubbyholes housing papyrus rolls. microfilm registers. card catalogs and inverted files coded onto discs. Many information retrieval systems rely on the use of a document surrogate. Though they might be surprise to discover it. nearly every information seeker uses an array of document surrogates. Summaries. tables of contents. abstracts. reviews, and MARC recordsthese are all document surrogates. That is, they stand infor a document allowing a user to make some decision regarding it. whether to retrieve a book from the stacks, whether to read an entire article, etc. In this paper another type of document surrogate is investigated using a grouping method of term list. lising Multidimensional Scaling Method (MDS) those surrogates are visualized on two-dimensional graph. The distances between dots on the two-dimensional graph can be represented as the similarity of the documents. More close the distance. more similar the documents.

  • References at the end of an academic paper are information that helps authors keep their research ethics, readers refer to related prior studies. Also references are useful information for linking citations and citations between articles. As bibliography metrics develops, bibliographic data is used as an important data for assessing the academic influence of countries, institutions and individual researchers. However, it is not easy to identify and link the reference data due to the diversity of the bibliographic citation formats, the loss of information due to the abbreviation of journal names and author names, and typos by authors. This study investigated the method of improving the bibliographic data mapping rate by analyzing the unmapped cases. As a result, it was found that the main cause of the article-reference mapping failure was the similarity of abbreviated journal names. Research team suggested that continuous management of journal title authority data and improving the DOI registration rate as ways to improve the identification and mapping rate. This study is differentiated from other studies in used database. Bibliography mapping was attempted for domestic and foreign integrated journal database that is mainly subscribed, used, published and cited in Korea. Through reference construction volume and mapping rate improvement, it can be used as citation analysis and service database reflecting domestic situation that is different from overseas citation index database.

  • In this study, the concept of 'Musim' presented by Baegun Hwasang was analyzed from the viewpoint of a bibliography. Major findings are as follows: First, it is reasonable to translate 'Musim' into Korean to mean (1) 'free from cares', (2) 'there is noting called a heart', and (3) 'no anxieties' according to the context of praises. Second, Musim by Baegun means 'calm mind without any trembles in ordinary times', 'unload any worries', and 'the spirit of awakening'. Such concepts of Musim agree with the praises of 'Awakening by seeing through a person's own heart' presented by Dalma Josa, and 'Unloading any worries' presented by Buddha. Therefore it is understood that Musim is the mental state of 'being free from cares which seek and hold', and Baegun Hwasang presents his experiential awakening 'by keeping his mind calm without any trembles in ordinary times, unloading any worries, and freeing himself from cares'. Third, it is confirmed that Musim by Baegun when compared with the praises presented by 'Gwageo 7 Buls' and 'Seocheon 6 Josas' in Jikji, firmly holds the ideas of Buddha's 'Unloading any worries' and Seocheon Josa's 'Neutral perspective based on double negations'. Therefore, Baegun Hwasang's 'Musimseon' which especially emphasizes 'Musim' is the method of meditation which most clearly inherited the nature of Dalma Seonjong or Yukjo Hyeneung, and Imjejong's meditation.

  • Jeong-Kuk Wonjong Gongsin-Nokgwon(靖國原從功臣錄券) is a book that recorded the titles of position and the names of retainers who helped the King Jung-Jong's revolution. This study aims to analyze the existing two books of Jeong-Kuk Wonjong Gongsin-Nokgwon, in order to figure out the reasons of grant, structure and forms, the characteristics of meritorious retainers' official positions and social status. The result shows that, Jeong-Kuk Wonjong Gongsin-Nokgwon was printed with the Choju-Gapin (初鑄甲寅) letter metal movable types. This book was composed of the beginning(卷首), the body(本文), and the end(卷末). Jeong-Kuk Wonjong meritorious retainers formed the total of 3,340 persons(1st grade: 418 persons, 2nd grade: 1,016 persons, 3rd grade: 1,906 persons) with 432 official titles. Also an analysis of their social status confirmed that 2,376 persons were "Yang-ban(兩班)" which constituted the largest group(2,376 persons: 71.1%), "Jung-in(中人)" were second group(494 persons: 14.8%), "Yang-in(良人)" were 272 persons(8.2%) and "Chun-in(賤人)" were 198 persons(5.9%).

  • This study was carried out to select DNA markers closely linked to brown planthopper (BPH) resistance gene originated from a rice cultivar 'Cheongcheong­byeo'. For the mapping of resistant gene to BPH, a doubled-haploid (DH) population was developed by anther culture of $F_1$ plants from a cross 'Cheongcheong­byeo/Nagdongbyeo'. In BPH bioassay and marker screen­ing for the DH population, the segregation of resistant and susceptible plants to BPH fitted to a 1:1 ratio. A total of 310 RAPDs of 520 markers showed polymorphism in parental survey using 'Cheongcheongbyeo' and 'Nag­dongbyeo'. In the analysis of relationship between BPH resistance and marker pattern for 40 DH lines, the OPE16 produced a specific dominant fragment, 700 bp, which was closely linked with BPH resistance gene of 'Cheong­cheongbyeo'. Based on the linkage analysis using 7 markers, BPH resistance of 'Cheongcheongbyeo' was mapped on chromosome 12, which was closely linked with $OPE16_{700}$ at a distance of 4.6 cM.

  • With the growth of aging population in Korea, a better care of chronic and other degenerative illnesses is urgently needed. Evidences suggest that this can be achieved through incorporating a wide range of care options, expanding beyond medical interventions. The aim of this study is to analyze the distribution of publically funded research to understand if the Korean research and development funding system matches various approaches and purposes to successfully tackle the chronic care needs of an aging society. We complied the list of funded projects to be analyzed by searching the National Technical Information Service database with key words such as aging society/senescence, chronic diseases, disability, and health promotion. Most projects were based on the biomedical approach with the purpose of establishing the etiology and clinical (treatment) interventions. Health promotion projects showed a distinctive distribution with more percentage of projects based on psycho-behavioral approaches while research on chronic diseases predominantly biomedical. It would be necessary to diversify publically-funded research projects to develop effective and efficient care technologies for the future.
