There is a original routine on dealing the first edition newspaper in Korea. Korean national morning newspapers print about 0.5% of total circulation as the first edition and sale those only in Seoul where the newspapers is published. The dead line of first edition is even about 5 pm. According to this routine which couldn't be found in the advanced western nations, like UK, USA etc., there can be some original characteristics and problems on the contents of Korean national morning newspapers. The present study investigated what the characteristics and problems means on the quality of newspaper and the free flow of diverse informations and opinions. Content analysis comparing the first edition to the last edition of 8 national morning newspapers is used to reveal the original characteristics and problems. Major findings in the result of the content analysis are three. First, the quality of the newspapers is damaged by the early dead line. Second, Inter-media agenda setting, which minor papers follow major papers on not only contents but also tone & manner, is manifest. Third, the early time publishing of the first edition allow the reported group including government and business sorter to take time to do make some negotiations on the articles about them, in which procedure even about 40% of total observed articles are changed(eg. removed, replaced, modified).

This study aims to determine the research trends in archival preservation through keyword analysis, understand the current research status, and identify the research topics' changes over time. The degree and betweenness centrality analyses were conducted and visualized on 463 "archival preservation studies" articles published from 2000 to 2021 in various academic journals, using NetMiner 4.0. The collected research papers were divided into three time periods according to when they were published: the first period (2000-2007), the second period (2008-2014), and the third period (2015-2021). The subject keywords for the research papers on archival preservation in Korea that have influence and expandability are as follows. Across all periods, these were "electronic records" and "long-term preservation." In addition, if taken separately per period, the "OAIS reference model" and "electronic records" dominated the first and second periods, respectively, while the "records management standard table" and "long-term preservation" both dominated the third period. A conceptual framework and theory-oriented study for archival preservation, such as "digital preservation," "digitalization," and the "OAIS reference model," dominated the first period. During the second period, more research focused on procedures and practical applications related to conservation activities, such as "electronic record," "appraisal," and "DRAMBORA." In contrast, the majority of the research in the third period was on technical implementation according to the changes in the records management environment, such as "data set," "administrative information system," and "social media."

In this research, the size-dependent impact of an embedded piezoelectric nanoplate subjected to in-plane loading on free vibration characteristic is studied. The foundation is two-parameter viscoelastic. The nonlocal elasticity is employed in order to capture the influence of size of the plate. By utilizing Hamilton's principle as well as the first- order shear deformation theory, the governing equation and boundary conditions are achieved. Then, using Navier method the equations associated with the free vibration of a plate constructed piezoelectric material under in-plane loads are solved analytically. The presented formulation and solution procedure are validated using other papers. Also, the impacts of nonlocal parameter, mode number, constant of spring, electric potential, and geometry of the nanoplate on the vibrational frequency are examined. As this paper is the first research in which the vibration associated with piezoelectric nanoplate on the basis of FSDT and nonlocal elasticity is investigated analytically, this results can be used in future investigation in this area.

White ledger usually includes white office paper, computer paper, and copy machine paper. Because these grades need high optical properties, fluorescent whitening agents (FWAs) are widely used in the papermaking process. FWAs are the most powerful and effective chemical used to obtain high CIE whiteness and ISO brightness in papers. The rising demand for white or ultra-white papers has increased the use of FWAs. However, FWAs used in white ledger can restrict its use, even though white ledger is widely used as a raw material in paperboard mills. Therefore, it is necessary to develop methods to control FWAs from white ledger to increase its use in paperboard mills. In this study, the behaviors of disulpho fluorescent whitening agent (D-FWA), tetrasulpo fluorescent whitening agent (T-FWA), and hexasulpho fluorescent whitening agent (H-FWA) during the recycling process were identified as a first step to remove FWAs from white ledger. We prepared four types of papers (dyed with D-FWA, T-FWA, and H-FWA), disintegrated these papers, and made handsheets. This recycling process was carried out three times in a laboratory. After each round of recycling, the hand-sheets' CIE whiteness and fluorescence index were measured, and the distribution of FWAs in the Z-direction was observed using CLSM images. FWA reductions in the model papers were calculated using fluorescence indices as a function of the number of recycling. FWAs in handsheets containing T-FWA and H-FWA decreased linearly as a function of the number of recycling, but D-FWA did not show a significant reduction in the fluorescence index after recycling. T-FWA and H-FWA showed similar distributions of D-FWA after recycling. Therefore, as much T-FWA and H-FWA as possible must be detached in the early processes of papermaking at paperboard mills.

The purpose of this research is to study technical and policy improvements of carrier billing services, which are a developing and growing industry, by adopting a meta-analysis method. Implications were derived from studying 15 years-worth of academic research papers (from 2001 to 2015), by analyzing the trends over a total of 109 such research papers on carrier billing services. First, looking at the characteristics of the main studies of the papers from 2008 to 2009, it papers appeared that dealt with preventing fraudulent transactions and preserving consumer protection. Privacy, policy proposals and studies for new systems were researched from 2010-2012. Service, success factors, damage prevention systems research, law, and institutions were discussed in 2013-2015 mainly. Second, the research showed that the number of carrier billing service studies increased due to social issues(telecommunications billing services deregulation, the emergence smartphones, fraud). Third, in sectorial research results, technology was the focus area of 47 papers (43.1%), the service sector was the focus of 39 pieces (35.8%) and law and policy improvement accounted for 23 pieces (21.1%). The study of technology and service areas was the most active and according to changes in the environment, law and policy improvement were second to most active. This study will contribute to improving relevant institutions and research directions about study trends in carrier billing services.

James Scarth Gale was a Canadian writer and Presbyterian missionary in Korea. He is A representative figure in Korean studies. Gale was the master of Korean studies at that time, which was based on Korean history, culture, folklore, and language. Gale was the first to will announce Korean Studies to the world. Gale's research and writings have spread to the continent of North America, including Europe and the United States, including Britain. At that time, Gale's study made Korean studies widely known to the world. There is a lack of research on Gale. It is because there is no material and documentary. Gale's documentary is on Thomas Fisher Rare Book Library on University of Toronto in Canada. Gale's documentary Name is Gale's Papers. The official name is MS Col 245, Gale James Scarth Papers. The papers consist mainly of holograph notes for and drafts and typescripts of Gale's works about Korea and his translations of English and Korean texts. In addition, the collection contains correspondence, commonplace books, diaries, the diary of his- second wife, Korean manuscripts collected by Gale, and published articles. The material dates from his work as a Presbyterian missionary in Korea(1888~1927) and from his retirement in England(1927~1937). The documentary Inclusive dates is 1888~1937, Extent is 24 boxes and 8.23 meters. Accession number is 87.046, Gift of George M. Gale in 1987. Liz Ridolfo helped collect the materials in Thomas Fisher Rare Book Library. Thanked. Gale's paper will be an important resource for modern Koreanology studies.
