  • This study discusses the fundamental properties of high performance concrete and autogenous drying shrinkage with the kinds and the adding amount of superplasticizer. According to results, drying shrinkage hardly shows differences by the kinds of superplasticizer, and is reduced with an increase of the adding ratio. Autogenous shrinkage is reduced in order of HP>HN>HM, but does not make a big difference. As the adding amount of superplasticizer increases, autogenous shrinkage is reduced due to a decrease of cement content which influences on autogenous shrinkage seriously.

  • In this study is investigated the various properties of concrete with the kinds of stabilizing agent of recycling water and solid content in order to suggest a practical use of recycling water. According to the results, fluidity and air content varies slightly with the kinds of stabilizing agent and solid content, but does not make a big difference. Setting time does not differ remarkably from plain concrete at 20℃, but is shortened with an increase of solid content. Bleeding is reduced more largely in the case of S than in the case of R, and is not influenced by solid content. Compressive strength is equal or decreases in comparison with plain concrete at solid content of I and 50%, and shows the highest value at solid content of 3%. Length change by drying shrinkage is larger than plain concrete at solid content of 5%, and decreases at solid content of I and 3%. Therefore, it proves that the influence of the kinds of stabilizing agent is minute, and solid content is most effective at 3%.

  • Our report refers to occidental vocal techniques from Greece until today. It is remarkable that even with poor anatomy knowledge, there were advices on styles given from very early periods, for both church and secular singing. During the 18th century, the names of "vox pectoris", "vox guturris" and "vox capitis" appear, nominations that somehow remain nowadays with great confusion about source of sound production and results of resonance. Vocal occidental styles developed different kinds of requirements from the singers, that had to adapt their vocal Possibilities to them. The same happened with "pop" song. Nowadays, all kinds of singers must have a conscious knowledge of its voice management to prevent vocal disturbances. We consider that the technique is the same, even when the singer has to sing Wagner, Debussy, Sconberg, Piazzola or Gershwin. The big changes occured at resonance levels, and because these different use of the vocal resonators the effects are quite different. In summary, the big differences on classical the effects are quite different. In summary, the big differences on classical and pop song are done on the different use of the resonators and its effects on the vocal tract. "Pop" singers, men and women, should be taught to use both registers, "modal" and "falsetto" to be able to reach the complete range of their songs without any harm to their larynxes. In our opinion, a good singing technique means that it could be adapted to every stylistic need. The same technique is adapted to the popular singer as well. The main difference lays on the use of resonators, pretty strong in the classic singer, weaken in the popular singer, on the volume and on the total extension of the voice. Breathing control, effortless emission and the use of "passage" at the right point should be taught to all singers, regardless of their style. (omitted)

  • Objectives : The aim of this study is to analyze the news articles related to Korean Medicine(KM) and compare trends in news reports from 2018 to 2022. Method : News articles related to KM were collected through the BigKinds, the news bigdata service of the Korea Press Foundation. News reports from 1 January 2018 to 31 December 2022 were searched. 2,950 news articles out of a total of 12,497 met the inclusion criteria. First, quantitative changes in media coverage were analyzed by year, media outlet, and month. For qualitative analysis, two authors independently coded the content of news articles, discussed them until consensus, and consulted with a third researcher to classify them. In addition, keywords extracted by the BigKind's Topic Rank algorithm were compared and analyzed in each year. Results : The number of news articles on KM decreased by 42% in 2022 compared to 2018. Over a fiveyear period, the Naeil Shinmun reported the most on KM among newspapers, while the Hankyoreh did the least. Among broadcasters, YTN reported the most and SBS did the least. When analyzing the reports by category, the most common was 'treatment', followed by 'prevention' and 'scientification'. As a result of extracting keywords with high weight and frequency, 'immunity' and 'immune system' ranked the first and second in 2018, while 'COVID 19' and 'medical law violation' did in 2022. Conclusion : The decrease in media reports on KM during the COVID-19 epidemic period seems to be due to the limited role of KM in responding to infectious diseases, and efforts to expand the scope of KM can induce increased media reports and social interest.

  • 이 연구에서는 한국언론진흥재단의 빅카인즈에서 제공하는 1990년부터 2022년까지 약 30년간의 5·18 관련 뉴스데이터를 빈도분석과 네트워크 분석하였다. 구체적으로 시기별과 지역별 기사량을 분석하여 양적 변화 추이를 살펴보았으며 동시 출현 키워드를 활용한 정부별 네트워크 분석을 통해 정부별 주요 키워드 간의 연결 구조를 탐색하였다. 분석 결과, 시기적으로는 사회적 이슈가 많았던 2019년의 보도량이 가장 많은 것으로 나타났으며 지역적으로는 전라권의 보도량이 가장 많은 것으로 나타났다. 그리고 네트워크 분석 결과, 정권이 5·18을 바라보는 인식과 정책에 따라 뉴스데이터 내 5·18과 관련된 단어에 차이가 있었다. 5·18 뉴스데이터 분석을 종합한 결과, 5·18이 지역과 상관없이 시간이 지남에 따라 민주화운동으로 자리매김해 나가고 있었으나 동시에 5·18에 대한 왜곡이 해소되지 못하고 있음을 확인하였다.

  • 빅데이터는 경제개발에서 흥미로운 기회와 도전을 보여왔다. 예를 들어, 농업 분야에서 날씨 데이터 및 토양데이터와 같은 복합데이터의 조합과 이들의 분석 결과는 농업종사자 및 농업경영체들에게 귀중하고 도움되는 정보를 제공한다. 그러나 농업 데이터는 센서들과 농업 웹 마켓 등의 다양한 형태의 장치 및 서비스들을 통해 매 분마다 대규모로 생성된다. 이는 데이터 수집, 저장, 분석과 같은 빅데이터 이슈들을 발생시킨다. 비록 몇몇 시스템들이 이 문제를 해결하기 위해 제안되었으나, 이들은 다루는 데이터 종류의 제약, 저장 방식의 제약, 데이터 크기의 제약 등의 문제를 여전히 가지고 있다. 이 논문에서는 농업데이터의 수집과 분석 플랫폼의 새로운 설계를 제안한다. 제안하는 플랫폼은 (1) Flume과 MapReduce를 이용한 다양한 데이터 소스들로부터의 데이터 수집 방법, (2) HDFS, HBase, 그리고 Hive를 이용한 다양한 데이터 저장 방법, (3) Spark와 Hadoop을 이용한 빅데이터 분석 모듈들을 제공한다.

  • 중국에서의 빅데이터의 발전 과정은 비교적 짧아 10년 정도에 불과하다. 따라서 실제 생활에서의 구체적인 활용도는 높지 않으나, 공급망분야에서는 일부 성과를 보이고 있다. 공급망이 실제로 작동하는 과정에서 발생하는 각종 데이터를 효과적으로 분류·활용할 수 있다면, 공급망 운영 과정에서 발생하는 '채찍효과' 또한 개선될 수 있을 것이다. 본 연구의 목적은 빅데이터를 활용한 공급망 협업 재고 관리 모델과 응용 프레임워크의 개발이다. 본 연구에서는 "채찍효과"가 가장 뚜렷한 소비 업종인 중국의 맥주 업계 공급 체인을 분석하였으며, 시뮬레이션 및 민감도분석을 위해 Vensim을 사용하였다. 본 연구의 모델을 적용한 결과 맥주 업계 공급 체인의 각 참여 주체의 재고변화가 적어지는 의미 있는 결과를 발견하였다. 또한 이러한 연구가 더 큰 데이터를 갖는 공급망 협업 재고관리모델에도 적용될 수 있는 가능성을 제사하고, 공급망 협업 재고관리모델에서 발생할 수 있는 문제점 및 대응방안을 제시하였다.

  • The primary purpose of this study is to compare a specific characteristic of Ulhacha -printed books with Imitating Ulhacha-printed books to distinguish from each others. Ulhacha was made in the first year of King Secho (1455) used before Hideyoshi's Invasion of Korea in 1592, there are many kinds books printed with it. For this reason, Ulhacha used to printed books for long period, the letters were worn down and must be filled up with su n.0, pplementary letters during the reign of King Chungchong and Myungchong. And at the early times of King Suncho, Many letters were su n.0, pplement and printed many kinds of books very neatly. Ulhacha-printed books were classified four sorts of books according to its characteristic to examine closely. From the latter half of the 16th century, the beginning of King Suncho, what is called Imitating Ulhacha-printed book, many copies of book were printed off imitated with Ulhacha. Imitating Ulhacha-printed books also classified four kinds of books according to its characteristic. Being glance at imitated letters, they were similar to Ulhacha and confused one thing with another. To distinguish Ulhacha-printed books from imitated letter ones, it is important to discriminate each others. Generally speaking, imitating Ulhacha letters were resemblant Ulhacha closely, it is not easy to distinguish Ulhascha from imitated letter. But they have a tendency to exhibit more thin style than Ulhacha and different from its size. Out of Ulhacha-printed books, the big letters in Hunsa printed in the 7th years of reign of King Secho and Hangulcha in Kumgang panya paramil kyong samgahae printed in the 13th years of the reign of King Sung chong come in to question. Nevertheless the big letters in Hunsa is consider to be that of Ulhacha and Hangucha in Kumgang panya paramil kyong samgahae also to be Ulhacha mixed with Hang lcha, disagreement of opinions has been opted to give rise to problem. In order to verify such a problem, it is more convenient to use OHP film copied those letters than the naked eyes. As a result of collating with OHP film, the problem was proven to be above-mentioned.
