Purpose: Primary malignant bone tumors are classified with mesenchymal sarcomas (MS) such as osteosarcoma and chondrosarcoma and small round cell sarcomas (SRS) such as Ewing's sarcoma and lymphoma. Radiological examinations for skeletal sarcoma were using MR scan in tubular bone sarcomas and CT scan in flat bone sarcomas recently. Both MR and CT scans show some findings of bone destruction and soft tissue mass but MR scans don't reveal a finding with mineralization relatively. So we investigated bone destructive pattern of skeletal sarcomas on both MR and CT scans for differentiation of MS and SRS. Materials and Methods: There are 28 MS and 26 SRS examined with MR or CT scans. The findings according to bone destructive pattern were divided to eccentric and concentric in 26 cases of tubular bone sarcomas with MR scan and 28 cases of flat bone sarcomas with CT scan. Results: MR images revealed eccentric destruction in 12 cases of 16 MS and concentric in all cases of 10 SRS (p>.01). CT images showed eccentric destruction in 10 cases of 12 MS and concentric bone destruction in 13 cases of 16 SRS (p>.01) Conclusion: The findings divided to eccentric and concentric bone destructive patterns were useful for differential diagnosis of MS from SRS on both MR and CT scans.

Engineering service is what is called a higher business which offers specialized engineering know-how and experience. Engineering service compaines offer Its specialized knowledge and experience to government, industry and commerce. Whether the task is to modernize plant equipment, to design a building or to manage construction, an engineering company will develop and implement the most appropriate and cost effective solution. Clients use the engineering service of firm knowing that the engineer′s professional judgement is not influenced or biased by other commercial affiliations. While benefiting from the diverse experience that professional engineers can apply to a specific problem, government and industry also reduce the need for permanent in-house engineering staff. Engineering firms may be specialized or multi-disciplinary.도말표본에서와 같이 제 14 일 이전에는 호중구가, 그 이후에는 단핵구가 주종을 이루었다.>18.9dB

This research analyzes the current status of personal name authority control and its impact on the end user searching against OPACs in public libraries in Korea. Further it also suggests the ways to improve the recall ratio in author search with a minimal modification, system-wise and authority-wise. on the KOLISNET as a stepping stone for other public libraries. Finally, a long-term plan for establishing proper authority work in public libraries including the National Library of Korea is briefly proposed. In order to find out whether authority works are conducted and examine how variant written forms of the same foreign name and variant names of the same person are treated, OPACS of the National Library of Korea, KOLISNET, and ten randomly selected public libraries were searched. Findings indicate that while the National Library of Korea was performing authority control, even incomplete, the rest did not appear to conduct any form or authority control. As a spinoff of the research, it is observed that in many public libraries their bibliographic records and retrieval methods are inaccurate, lacking consistency, and incomplete. In sum. it is strongly recommended that (1) as a start for authority work among public libraries personal name authority control should be conducted to enhance the identifying and collocating functions in OPACs, (2) a shared authority database, for which the National Library of Korea's authority database might be used. should be built for Public libraries.

Authors previously reported the results of analyses of COGs (Clusters of Orthologous Groups of proteins) in 711 prokaryotes. The data of COGs were significantly updated for 2020 using 1,309 prokaryotic genomes. Here, we report the results of analyses of 3,455,853 proteins comprising 4,877 updated COGs in terms of COGs and prokaryotes. The numbers of COGs in each prokaryote ranged from 97 to 2,281, with an average of 1,430.0 and a standard deviation of 414.2. Mean numbers of COGs at the phylum level were minimal 497.86 for Mollicutes and maximal 1,642.90 for Cyanobacteria. The top 10 species with the highest COG retention numbers were all Proteobacteria, and 9 out of the bottom 10 were those that could not be cultured in vitro. The numbers of proteins belonging to each COG ranged from 2 to 22,048, with over 12,000 proteins up to the top 11. Five of the top 11 were COGs that bind to DNA and were involved in the gene expression, indicating the importance of regulating gene expression in prokaryotes in a changing environment. COG data are expected to be widely utilized as they can be used for the identification of genes included in the genome and the selection of genes for the strain improvement.

Identifying behavioral errors of seafarers that have led to marine accidents is a basis for research into prevention or mitigation of marine accidents. The purpose of this study is to estimate the optimal probability distribution function needed to model behavioral errors of crew members into three behaviors (i.e., Skill-, Rule-, Knowledge-based). Through use of behavioral data obtained from previous accidents, we estimated the optimal probability distribution function for the three behavioral errors and verified the significance between the probability values derived from the probability distribution function. Maximum Likelihood Estimation (MLE) was applied to the probability distribution function estimation and variance analysis (ANOVA) used for the significance test. The obtained experimental results show that the probability distribution function with the smallest error can be estimated for each of the three behavioral errors for eight types of marine accidents. The statistical significance of the three behavioral errors for eight types of marine accidents calculated using the probability distribution function was observed. In addition, behavioral errors were also found to significantly affect marine accidents. The results of this study can be applied to predicting marine accidents caused by behavioral errors.

In today's increasingly data-intensive academic environment, data is becoming the foundation of academic communication as a research outcome rather than a research by-product. However, there is a limit to guaranteeing actual data reuse only by expanding the data supply or securing accessibility. In order to overcome this, it is necessary to understand the data reuse behavior and data needs in-depth. Therefore, this study attempted to identify the major data reuse behavior and data needs among researchers. To this end, the authors of KCI papers among the data reuse documents of the Korea Social Science Data Archive (KOSSDA) for the past 3 years were targeted. An in-depth interview was conducted with 12 researchers who accepted the interview. As a result, factors considered when reusing data were personal, economic, technical, and social aspects, and it was found that the data itself was used or contextual information of the data was used depending on the purpose of data reuse. The path to acquiring data is a web-based source of information, and a path through informal communication can also be found. In terms of the data needs, it was found that they prefer English, the United States, and institutional producers. Also they have a clear preference for quantitative data from an interviewer-filled interpersonal interview survey method, rich metadata along with raw data, and data that contains identification information. However, due to the lack of confidence in the value, it is negative for the use of data with controlled access and use, and it is difficult to confirm a clear preference because there is no similar data available for selection in terms of size and freshness.

In a situation where OA papers are increasing, POI, which indexes how open the research activities of individual researchers are, is drawing attention. This study investigated the existence of OA papers and the OA method published in international academic journals by domestic LIS researchers, and derived the researchers' POI based on this. In addition, by examining the relationship between the POI index and the researcher's amount of research papers, the research sub field, and the foreign co-authors, it was analyzed whether these factors are relevant to the researcher's POI. As a result, there were 492 papers by 82 researchers whose OA status and method were normally identified through Unpaywall. Second, only 20.7% of papers published in international journals were open accessed, and almost cases were gold and green methods. Third, there were many papers in text mining in medical journals, and the papers opened in the green method are open in institutional repositories of foreign co-authors or transnational subject repositories such as PMC. Third, the POI index was relatively higher for researchers in the field of informetrics, machine learning than other fields. In addition, it was analyzed that the presence or absence of overseas co-authors is related to OA.

The purpose of this study is to design textbook metadata as a basic task for building a textbook database. To this end, reading textbooks were defined as a category of textbooks, and a metadata development methodology was established through previous research. In order to ensure that bibliographically essential elements are not omitted, the catalog description elements of institutions that collect, accumulate, and service textbooks such as the National Library of Korea were investigated. The elements of Dublin Core, MODS, and KEM were mapped to derive elements suitable for describing textbooks. Finally, a set of textbook metadata elements consisting of 14 elements in three categories - bibliography, context, and textbook characteristics were presented by adding publication type, genre, and curriculum period elements. The 14 elements are titles, authors, publications, formats, identification sign, languages, locations, subject names, annotation, genres, table of contents, subjects, curriculum period, and curriculum information. In this study, we contributed to this field by discussing how to organize textbook resources with national knowledge resources, and in future studies, we proposed to evaluate usability by applying metadata elements to actual textbooks and revise and supplement them according to the evaluation results.

This study aims to propose the considerations for developing the guidelines for recording a preferred title in musical works by analyzing the RDA rules and guidelines of several national libraries. First, RDA rules were analyzed, and the primary rules for consideration were examined by reviewing RDA application guidelines from eight national libraries that have developed their own guidelines for alternatives and options of RDA rules. Then, by analyzing the contents of each guideline, including MLA, LC-PCC, and DACH, practical considerations was to provide. First, the original language title should be adopted in the selection of preferred title, but if the title in the original language is not suitable for domestic users, the title in other languages should be used. Second, the preferred title was examined in aspects of works with one part, works with more than one part, the complete works of one author, the compilation of a specific type of composition, the incomplete compilation, and the compilation of several composers. Third, medium of performance, numeric numbers, key, and other identifying characteristics were presented as additional factors for consideration in the recording. Fourth, it is necessary to designate or present a control vocabularies for the types of compositions and the medium of performance. This study suggests considerations in developing guidelines for recording the preferred title for RDA musical works, and it will be possible to contribute to the development of rules related to preferred titles for musical works and guidelines for recording the preferred title for musical works in libraries.
