This study studied a system that can redesign the production site layout and respond with dynamic simulation through fabric production process innovation for smart factory promotion and digital-oriented decision making of the production process. We propose to reflect the required throughput and throughput per unit facility of fabric production process as probability distribution, and to construct data-driven metabolism such as data collection, data conversion processing, data rake generation, production site monitoring and simulation utilization. In this study, we demonstrate digital-centric field decision smartization through architectural design for the smartization of fabric production plants and dynamic simulations that reflect it.

기상청에서 운용하는 268개의 가속도 관측망에 대한 방위각 보정값을 측정하기 위해 배경잡음 교차상관 방법을 사용하였다. 이 방법은 배경잡음 자료를 사용하기 때문에 원거리 지진자료를 사용하는 방법과 달리 특정 조건에 맞는 지진을 선정할 필요가 없고, 한반도와 같은 조밀한 관측망에 적용하여 단기간의 연속 파형 자료만을 사용해 신뢰할 수 있는 방위각 보정값을 측정할 수 있다. 계산에는 2020년 1월부터 2020년 2월까지 총 268개의 기상청 가속도 관측망에 기록된 3성분 연속 파형 자료를 사용했다. 계산된 결과를 보면 기존에 원거리 지진자료를 사용한 결과와 매우 유사하며, 기존 결과에서 누락된 가속도 관측소들을 포함한 대부분 관측소의 방위각 보정 계산 결과가 표준편차 5o 이하로 안정적으로 계산되는 것을 확인할 수 있다. 따라서 본 연구를에서 사용한 방법을 활용해 기상청 가속도 관측소에 대한 방위각 보정값을 지속적으로 모니터링하고 측정된 결과를 활용하면, 가속도 자료의 수평 성분을 활용한 다양한 연구들에 활용할 수 있을 것이다.

Using the big data analysis of the Choseonwangjosilrok, this research aimed to figure out the fruits’ types, prevalence, seasonal appearances as well as the royalty’s perspective on fruits during Choseon period. Choseonwangjosilrok included nineteen kinds of fruits and five kinds of nuts, totaling 1,601 cases at 72.8% and 533 cases at 24.2% respectively. The text recorded fruits being used as: tributes for kings, gifts from kings to palace officials, tomb offerings, county specialties, trade goods or gifts to the foreign ambassadors, and medicine ingredients in oriental pharmacy. Seasonally the fruits appeared demonstrating an even distribution. Periodic characteristics were observed in decreasing quantity chronologically. From fifteenth century to nineteenth century, the fruits with timely features were seen: 804 times at 36.6%, 578 times at 26.3%, 490 times at 22.3%, 248 times at 11.3%, and 78 times at 3.5% respectively. In fifteenth century: citrons, quinces, pomegranates, cherries, permissions, watermelons, Korean melons, omija, walnuts, chestnuts, and pine nuts appeared most frequently. In sixteenth century: pears, grapes, apricots, peaches, and hazelnuts appeared most frequently. In seventeenth century: tangerines and dates appeared most frequently. In eighteenth century, trifoliate orange was the most frequently mentioned fruit.

This study aimed to analyze the periodic prevalence of the vegetables during the Joseon era with JoseonWangjoSilrok as a reference. The JoseonWangjoSilrok articles were collected from the Guksapyeonchanwewonhwe site, using web-crawling techniques to extract the relevant information. Out of 384,582 search results, 9,560 articles with vegetable-related keywords were found. According to the annual average vegetable recordings during the regimes of various kings, there were two peaking curves in the 15th and 18th centuryJoseon. The found was: 2,750 in the 18th century, 2,529 in the 15th century, 1,424 in the 16th century, and 1,018 in the 19th century. A Variable Interest Index was designed to ascertain the interestin vegetables of the 27 Joseon kings. The king most interested in vegetables was the 19th king Sookjong. The second most interested king was Youngjo. There were 5,105 vegetable-related findings within the JoseonWangjoSilrok related to specific species and categories of vegetables. Among the words found: 1,194 were stem-leaves vegetables (23.39%), 1,017 were root vegetables (19.92%), 1,148 were flower-fruit vegetables (22.49%), 1,144 were spice vegetables (22.41%), 95 were mushrooms (1.86%), and 507 were seaweeds (9.93%). Statistical analysis using ANOVA revealed the chronological factors that affected the vegetables’ prevalence index.

We analyzed the records on the reign style and the calendrical data presented in the Samguksagi (History of the Three Kingdoms) and the epigraph of the Three Kingdoms (Silla, Goguryeo, and Baekje) period in Korea (B.C. 57 – A.D. 935) to verify the chronological tables of the period that are currently in use. For the epigraph of the Three Kingdoms of Korea, we utilized the database provided by the National Research Institute of Cultural Heritage. By analyzing the records on the reign style, first, we found that the Yeonpyo (Chronological Table) of the Samguksagi is tabularized using the reign style of the Caowei for the period of Three Kingdoms of China (Caowei, Shuhan, and Sunwu) (A.D. 220 – 280). Second, we found that the reign style of the Silla was promulgated during the reign period of a king, which was usually promulgated when a king acceded in China. Third, we found that the reign styles presented in historical materials showed agreement with those of the Yeonpyo except for two cases in the Goguryeo. Concerning the records on the calendrical data, first, we confirmed that accession years of kings Michu, Beobheung, Seondeok, Minae, Gyeongmun, and Seongdeok. On the other hand, we found probable errors in the record of accession years for the kings Munja, Wideok, Aejang, and Heonan. Next, we found that the records of the length of a lunar month, leap month, and cyclic day showed agreement with the current chronological table except for several cases. In particular, cyclic days in the solar eclipse account had a relatively large number of discrepancies. We believe that these errors might have been caused by the inaccurate identification of a year in the records of the Three Kingdoms while determining the year by referring to Chinese historical documents. Finally, we found that the starting point was included while counting a year, at least from the Three Kingdoms period, similar to the current method of counting age in Korea. However, we point out that the starting point should be excluded when the term “after” is used in the expression. We believe that this study is very useful to verify the current chronological table of the Three Kingdoms period in Korea.

By adopting a usage-based approach to language acquisition, this study investigated the emergence and development of L2 constructional knowledge. A total of 19 English verb-argument constructions (VACs) and their associated verbs were extracted from a learner corpus and three verbal fluency tasks, each conducted in L1 and L2 English and L1 Korean. We compared verb usage in the target VACs across proficiency levels between the L1 and L2 groups and between data types for VAC productivity and verb-VAC associations. The results identified three stages through which Korean learners’ VAC knowledge develops in L2 English: emerging through the frequent use of a few general verbs, expanding the range of verbs associated with a VAC to include more specific and prototypical verb types, and then developing them into a creative constructional schema. Moreover, we determined similarities between L1 and L2 English VAC knowledge in higher L2 proficiency levels, as well as L1 Korean influences related to L1 typology and L1 collocational transfer.

본 연구는 골프참여자들의 골프 디바이스 데이터의 신뢰, 만족 및 인지된 경기력에 대한 관계를 규명하는데 목적이 있다. 연구대상은 일반 골프참여자들을 대상으로 서울, 경기도, 강원도, 경상도, 충청도, 전라도, 제주도 등 7개 시, 도 지역에 온라인 설문을 통해 수집하였으며, 온라인 설문은 총 328부를 수집하여 사용되었다. 수집된 자료는 SPSSWIN 프로그램과 AMOS 를 이용하여 자료를 분석하였으며, 빈도분석, 확인적 요인분석, 신뢰도 분석, 상관관계분석, 구조방정식모형분석 및 경로분석을 실시하였다. 변인 간 관계를 검증한 결과는 다음과 같다. 첫째, 골프참여자들의 골프 디바이스 데이터의 신뢰는 만족에 정( + )에 유의한 영향을 미쳤다. 둘째, 골프참여자들의 골프 디바이스 데이터의 신뢰는 인지된 경기력에 영향을 미치지 않았다. 셋째, 골프참여자들의 골프 디바이스 데이터 만족은 인지된 경기력에 영향을 미치지 않았다. 결론적으로 골프참여자들이 골프 디바이스를 통해 제시된 데이터를 신뢰하고 만족한 결과를 얻고 있다는 것을 알 수 있었다. 하지만 인지된 경기력에는 영향을 미치지 못했다는 점에서 골프참여자들은 골프 디바이스를 경기력을 높여준다는 생각보다는 골프를 하기 위해서 당연히 사용해야 되는 것으로 생각할 수 있다.
