Bibliographical Description for Revolutionary Historical Archives is created to describe records at the item level. It defines descriptive elements, punctuations, formats and methods. Descriptive elements are composed of 20 elements, each of which is either mandatory or optional. Mandatory elements are: repositories codes, documents codes, dates, creators, title, classification codes, and subject vocabularies. Abstracts were previously included in card cataloging and are removed in the computerized system. New elements, such as "uncontrolled vocabularies," "name of places," "personal names," "organizational structures" and "meetings," are added to allow keyword search. Considering that subject vocabulary searches are the most important in computerized systems, however, Guidelines for the Subject Indexing for Revolutionary Historical Archives as well as Subject Headings, as a result from the Guidelines, are created. The most extraordinary features in Chinese archival description are said to be the Guidelines for the Classification Indexing for Revolutionary Historical Archives and Materials as well as the Classification Scheme, both of which are created to allow subject search of records content. It is because Chinese practice of records management distinguishes the classification for arrangement from that for retrieval. Chinese archival description is, therefore, composed of bibliographic description rules, subject headings, and the classification scheme for retrieval.

South Korea has the most advanced technology in the Fourth Industrial Revolution era because of its high-speed Internet commercialization. However, the industry is shrinking due to its various regulations in building and its utilization of personal information as big data. Currently, South Korea's personal data utilization business is in its early stages. In the era of the 4th Industrial Revolution, it is difficult for startups to use data. There are various causes here. Above all, legal regulations to protect personal information are emphasized. This study confirms that transactions of personal medical records through My Data can be made. Moreover, it confirms that there is a need for a mediating role between stakeholders. This study lacks statistical access in the process of performing stakeholder roles. However, personal medical records will be traded safely in the future, and new subjects will enter the market. Furthermore, the domestic bio-industry will develop. Through this study, various problems were derived in establishing Medical MyData in Korea. Moreover, it looks forward to continuing various studies in the health care sector in the future.

Graphis upretii is a new lichen species discovered in Vietnam. The species is characterized by a loosely corticate, rough, whitish grey to greyish green thallus, elongate and irregularly branched lirellae with an apically thin complete thalline margin (negrosina morph), laterally carbonized, entire proper exciple, clear hymenium, hyaline, 16~20 transversely locular ascospores, and about $50{\sim}95{\times}10{\sim}15{\mu}m$ in size. In addition, members of the taxon produce norstictic and stictic acids. Currently, the lichen flora of Vietnam include Arthonia radiata, Brigantiaea tricolor, Coenogonium implexum, Dirina paradoxa, Herpothallon sipmanii, Pertusaria pertusa, and Sarcographina cyclospora.

XML 이 명실상부한 데이타 교환 표준 언어로서 자리 잡아 감에 따라, 효율적인 XML 질의 처리 지원에 대한 많은 연구가 진행되어 왔다. XML 질의 처리에서 가장 중요한 고려 사항은 ‘어떻게 XML 경로식을 효율적으로 처리할 것인가’ 하는 것이다. 기존의 몇몇 연구들은 질의를 구성하는 각 라벨들에 대응되는 모든 데이타에 대해 일련의 조인 연산을 수행하는 방식으로 결과를 생성하였다. 다른 몇몇 연구들은 질의에 포함된 경로를 찾기 위해 RDBMS의 문자열 비교 연산자를 사용하고 찾은 경로들에 대응되는 레코드를 추출하여 결과를 생성하였다. 본 연구에서 우리는 경로 포함 관계를 기반으로 한 새로운 질의 계획 생성 방식과 이를 지원하기 위한 두 개의 새로운 조인 연산자들을 제안하였다. 제안한 조인 연산자들은 질의에 속한 경로들과 관련된 데이타만을 입력 데이타로 사용하며, 매우 적은 비교 연산만을 수행한다. 그리고 파이프라인 기법을 적용하여 결과를 생성한다. 우리는 제안한 기법이 다른 이전 기법들에 비해 높은 성능을 보임을 분석과 실험을 통해 증명하였다.

The dynamic structural responses are sensitive to the time-frequency content of seismic waves, and seismic input motions in time-history analysis are usually required to be compatible with design response spectra according to nuclear codes. In order to generate spectra-compatible input motions while maintaining the intrinsic non-stationarity of seismic waves, an improved time-domain approach is proposed in this paper. To maintain the nonstationary characteristics of the given seismic waves, a new time-frequency envelope function is constructed using the Hilbert amplitude spectrum. Based on the intrinsic mode functions (IMFs) obtained from given seismic waves through variational mode decomposition, a new corrective time history is constructed to locally modify the given seismic waves. The proposed corrective time history and time-frequency envelope function are unique for each earthquake records as they are extracted from the given seismic waves. In addition, a dimension reduction iterative technique is presented herein to simultaneously superimpose corrective time histories of all the damping ratios at a specific frequency in the time domain according to optimal weights, which are found by the genetic algorithm (GA). Examples are presented to show the capability of the proposed approach in generating spectra-compatible time histories, especially in maintaining the nonstationary characteristics of seismic records. And numerical results reveal that the modified time histories generated by the proposed method can obtain similar dynamic behaviors of AP1000 nuclear power plant with the natural seismic records. Thus, the proposed method can be efficiently used in the design practices.

중국 명대에 간행된 "석씨원류"는 우리나라에서 불암사와 선운사에서 2회 간행되었다. 그런데 불암사판은 간기가 분명하여 판각 연대를 정확하게 알 수 있으나, 이에 비해 선운사판은 간기에 간행사찰만 명시되어 그 판각 시기에 문제가 있었다. 그리하여 이 연구에서는 선운사의 사적기와 국립도서관 소장본 등 관련 자료를 검토한 결과, 종래 통용되고 있는 1648년이 아니라 1710년에 판각되었다는 새로운 사실을 밝혀냈다.

Since 2013, more than 100 Entoloma (Entolomataceae, Agaricales) collections have been made during field investigations of mushroom flora in Korea. Among these collections, three Entoloma species were identified as new records from Korea. Morphological examinations were made based on the macro- and micro-morphological features of the isolates collected during field visits. To ensure the identity of the isolates at the species level, DNA sequences from four gene regions (rpb2, ITS, 28S, and mtSSU) were compared. To the best of our knowledge, these are the first records of E. aprile, E. chytrophilum, and E. hirtipes in Korea. Comprehensive descriptions, photographs, and phylogenetic examinations are presented here.

Two species of mantid shrimps were collected from southern part of Korea and identified as Kempella mikado and Squilloides leptosquilla of the Squillidae. The former species is characterized by having a dactylus of the raptorial claw with six teeth, only the fifth thoracic somite with a single spinous lateral process, and the fifth abdominal somite with a pair of black dorsal patches. However, the latter species is characterized by having a dactylus of the raptorial claw with four teeth, and the fifth to seventh thoracic somites each with a single lateral process. Both species are described with figures and photographs. The present records are extensions of their geographical distributions and new records in Korea. Hence, a total of six species of the stomatopods have been recorded in Korea up to date: Oratosquilla oratoria, Faughnia formosae, Taku spinosocarinatus, Chorisquilla spinosissima, Kempella mikado, and Squilloides leptosquilla.

Two species of crabs, Homola orientalis Henderson, 1888 and Pseudomicippe nipponica (Sakai, 1938), are described and illustrated for the first time in Korea. Homola orientalis was collected at 30 m depth by trap from Busan, and P. nipponica was collected on the intertidal region in Seongsanpo, Jejudo Island. Homola orientalis is the first species of its family in the region. The family Homoldae is characterized by a linea homolica on the carapace and they carry camouflage in the form of sponges or cnidarians with subchelate of the fourth ambulatory legs. The Korean brachyuran fauna now comprises 223 species including the new records from this study.
