본고는 링크드데이터를 위한 도서관 분야의 온톨로지 BIBFRAME 개발에 따라 국내에서 BIBFRAME 적용을 위한 구체적인 방안을 마련하는 것이다. 이를 위해 문헌연구, 사례조사, 설문조사를 실시하였고, 사례조사로 BIBFRAME을 개발한 미의회도서관과 BIBFRAME 프로젝트를 진행하는 LD4P를 분석하고, 설문조사에서는 국내 목록사서를 대상으로 링크드데이터 관련 용어의 이해도, 링크드데이터 구축을 위해 필요한 조건 등에 대해 조사하였다. 이를 바탕으로 국내에서 BIBFRAME을 도입하기 위한 적용방안을 다음과 같이 제시하였다. 첫째, 이름전거, 주제명 등의 기존 전거데이터를 링크드데이터로 출판하는 것뿐만 아니라 도서관에서 통제어휘로 사용하거나 데이터 값으로 사용하는 용어집도 링크드데이터로 생성해야 한다. 둘째, 국내에서 BIBFRAME의 적합성을 판단하고, 확장 모델링을 개발할 필요가 있으며, KORMARC과의 매핑 테이블 작성과 변환기 및 입력기의 시스템 개발도 요구된다. 셋째, BIBFRAME과 같은 링크드데이터 구축이 사서의 고유 업무가 될 수 있도록 사서를 대상으로 한 체계적인 교육프로그램이 개발되어야 한다. 따라서 본 연구는 국내에서 BIBFRAME 구축을 위한 실질적인 적용방안을 모색하였다는 점에서 그 의의가 있다.

빅데이터는 초연결·초지능·초융합으로 대표되는 4차 산업혁명의 핵심 동력으로 이노베이션 창출, 비즈니스 모델 발굴을 위한 데이터 공유, 연계·활용이 중요하다. 그러나 빅데이터 플럇폼이 공유·연계를 고려하지 않고 폐쇄적으로 구축될 경우 양질의 풍부한 데이터 확보 및 활용이 어렵다. 따라서 본 논문은 데이터 생산·구축 및 연계·유통을 활성화 할 수 있도록 빅데이터 플랫폼의 다양한 사례를 비교·분석하여 빅데이터 플랫폼 인프라의 발전 방향을 제시한다.

The dielectric breakdown of epoxy composites used for transformers was experimented and then its data were applied to Weibull distribution probability. First of all, speaking of dielectric breakdown properties, the more hardener increased, the stronger breakdown strength became at low temperature because of cross-linked density by the virtue of ester radical. The breakdown strength of specimens with filler was lower than it of non-filler specimens because it is believed that the adding filler forms interface and charge is accumulated in it, therefore the molecular motility is raised and the electric field is concentrated. In the case of filled specimens with treating silane, the breakdown strength become much higher. Finally, according to Weibull distribution analysis, reducing breakdown probability of equipment insulation lower than 0.1 % level requires the allowable field intensity values to be kept under 21.5 MV/cm.

Silver barb (Barbonymus gonionotus) is among the most economically important freshwater fish species in Thailand. It ranks fourth in economic value and third in production weight for fisheries and culture in Thailand. An XX/XY sex-determination system based on gynogenesis was previously reported for this fish. In this study, the molecular basis underlying the sex-determination system was further investigated. Genome-wide single-nucleotide polymorphism data were generated for 32 captive-bred silver barb individuals, previously scored by phenotypic sex, to identify sex-linked regions associated with sex determination. Sixty-three male-linked loci, indicating putative XY chromosomes, were identified. Male-specific loci were not observed, which indicates that the putative Y chromosome is young and the sex determination region is cryptic. A homology search revealed that most male-linked loci were homologous to the Mariner/Tc1 and Gypsy transposable elements and are probably the remnants of an initial accumulation of repeats on the Y chromosome from the early stages of sex chromosome differentiation. This research provides convincing insights into the mechanism of sex determination and reveals the potential sex determination regions in silver barb. The study provides the basic data necessary for increasing the commercial value of silver barbs through genetic improvements.

본 연구에서는 기존에 개발된 상수도 관련 GIS(geographic information system)에서 관로해석을 위한 자료를 자동으로 입력할 수 있고, 사용자를 위한 GUI(geographic user interface)를 제공하는 GNLP(GIS linked non-linear pipe network analysis program)프로그램을 개발하였다. 관로시스템의 수리해석은 Hazen-Williams의 손실수두방정식을 기초로 한 비선형 해석기법을 이용하여 시행하였으며, 데이터베이스 응용 프로그램을 작성하기 위해서 관계형 데이터베이스 관리시스템(RDBMS ; relational database management system)인 Microsoft사의 Microsoft Access를 사용하였다. 이 GNLP 프로그램은 실제 관망설계자가 관로시스템의 수리해석에 필요한 자료의 입력을 용이하게 할 수 있도록 시스템환경을 개선하였다. 그리고 압력 및 유량 등 관로시스템의 수리적 해석 결과를 표 및 챠트 형태로 출력이 가능하고, Excel 파일로 변환이 가능하다. 또한 GIS의 중요 요소인 질의(query) 기능이나 분석된 자료를 확인하고자 할 때 이를 효과적으로 디스플레이가 가능하도록 개발되었다.

Purpose - This study's the ultimate goal is to analyze competitiveness improvement on multinational enterprises as firstly providing which factors are to strengthen or weaken competitiveness, secondly investigating if hypotheses development and research design is correct and thirdly finding significant implications for research and practices across country specific advantage. Design/methodology - Using feedback data provided by 250 firms, we extracted variable factors and hypotheses, which were empirically carried out by reliability and validity testing, correlation analysis, path analysis, and confirmatory factor analysis to prove which factors are to make the positive effect on the improvement of overseas subsidiaries' management performance and competitiveness. Findings - Through proceeding empirical analysis study, we found out that technology management capability, knowledge management capability, and local management capability had a statistically significant effect on the improvement of overseas subsidiaries' competitiveness, while linked activity capability revealed a negative effect. Originality/value - During business globalization, overseas investments and establishment of overseas subsidiaries have been essential. It is anticipated that this study results would be meaningful for analysis on multinational enterprises' competitiveness and helpful in promoting their entry into Korean market and enhancing their competitiveness. This paper would also help Korea government develops new FDI model and induce more investment from global major companies to Korea region.

The purpose of this study was to examine the relationship between perceived parenting behaviors and dispositional gratitude of adolescent children in Korea. Participants consisted of 403 high school students from the Seoul and Gyeonggi areas. Dispositional gratitude of adolescents and parenting behaviors (including respect, lessons, attention, and lack of trust) were reported by adolescents. The data were analyzed using descriptive statistics, Pearson's correlations, and multiple regression analyses. The results were as follows. First, the average levels of parental lack of trust and maternal attention were different as a function of gender. Second, girls showed higher levels of dispositional gratitude than boys. Third, greater parental respect, lessons, and attention were linked to higher levels of dispositional gratitude of adolescent children; whereas lack of trust was linked to lower levels of dispositional gratitude. Fourth, paternal lessons was the most meaningful factor in explaining the level of dispositional gratitude in boys while maternal attention was the most meaningful factor in girls. These results suggest that parents play an important role in the development of dispositional gratitude in adolescents. Differential parental roles were discussed to promote the level of dispositional gratitude for adolescents.

Data provider and data user are linked together by suitable data. This implies that for a successful relationship the provider knows what kind of data, whether original or processed, is needed by the user and that the user articulates his needs to the provider. The co-operation between Korea and Austria aims at identifying these needs and to provide suitable routines for the processing of satellite data. Partners of this co-operation are the Korea Aerospace Research Institute, ARC Seibersdorf research and GeoVille. While the focus of the former lies in the development and running of satellite systems, the latter two have experience in the development and set up of applications in the field of remote sensing. Based on the complementary know-how by the institutions involved, projects were set up in Korea and Austria to fulfill this need and establish a pilot data feed for governmental applications.

In this paper, we propose an approach to generate machine readable context annotations for SPARQL Results. According to W3C Recommendations, the retrieved data from RDF or OWL data sources are represented in tabular form, in which each cell's data is described by only type and value. The simple query result form is generally useful, but it is not sufficient to explain the semantics of the data in query results. To explain the meaning of the data, appropriate annotations must be added to the query results. In this paper, we generate the annotations from the basic graph patterns in user's queries. We could also manipulate the original queries to complete the annotations. The generated annotations are represented using the RDFa syntax in our study. The RDFa expressions in HTML are machine-understandable. We believe that our work will improve the trustworthiness of query results and contribute to distribute the data to meet the vision of the Semantic Web.
