  • In this study, the current researches and the developing trend of the high burning rate solid propellants were briefly introduced and the effects of burning rate modifiers in the propellants on the combustion properties were reviewed. At the same time, bis(ethylenediamine)copper perchlorate(BECP) has been prepared as a burning rate modifier, and the burning characteristics were investigated in Butacene/AP propellants. The results showed that the metal complex, BECP, can increase remarkably the burning rate of high burning rate Butacene/AP propellants.

  • To address recent environmental pollution, bio plastics such as biodegradable, oxo-biodegradable, and bio-based plastics have attracted much attention in a variety of industrial fields. The critical disadvantages of the weak mechanical strength and expensive product cost were gradually solved by extensive researches. As an alternative for petroleum-based plastics, the bio plastics have been applied to various items. To popularize the bio plastics, certification marks and technical standardization have been developed in the world. This article provide an over view on the recent trend on the commercialization and national certification marks.

  • As consumption pattern and fashion communication become digitalized, fashion houses are being inherited by creative directors owing to their expanding role. While the roles and responsibilities of creative directors have been changing extensively along with the dynamic nature of the fashion industry, researches on creative directions have mostly focused on luxury brands. This study examined the creative direction of John Galliano for Maison Margiela, a conceptual brand to be maintained by a creative director. To analyze this, the authors established a creative direction analysis model constituting five elements: brand heritage, trend, democratization, brand status, and persona, drawing on the luxury brand architecture by Kapferer and Bastien. Thus, Galliano has maintained anonymity as a heritage of Maison Margiela, expanding the existing Replica lines, and introduced fashion shows focusing on current issues or social phenomena. As a democratization strategy, he directed the brand to associate with more popular brands or expanded diffusion lines to secure broader customer base, while demonstrating couturier-like showmanship in the media and establishing his own persona. His direction for Maison Margiela recreates and expands brand heritage by transforming the brand philosophy. Therefore the new creative direction communicates with the wider public and diversifies customer bases through democratization strategies, while building Galliano's own persona.

  • XML is rapidly spreading as a standard for data representation and exchange, and XML documents are adopted in various applications. According to this trend, researches in database has also focused on efficient storage and retrieval of XML documents. Recently, major (object) relational DBMS vendors support XML functionality, and several native XML DBMSs have been developed in academic or industry side. In addition, various benchmarks have been proposed so as to evaluate these na database performance. In this paper, we evaluate the XBench benchmark using a commercial object-relational DBMS, analyze its performance, and investigate the future improvements of object-relational DBMSs for XML support.

  • This investigation reviewed 74 studies related to pregnancy and childbirth of married immigrant women that were selected from national dissertations and others in journals released in the past 10 years from 2007 that were identified using http://www.riss.kr. Analysis on the trend of research was done through result variances used in academic fields, planning researches, main themes and mediative studies. Of the 74 studies, 28 were national dissertations (38.6%) and 46 were articles in academic journals (61.4%), 37 of which were performed by nursing departments (50.0%). Additionally, 45 were quantitative (60.8%) and 29 were qualitative (39.2%) and descriptive research, and 22 in total(29.9%) took the most of the part of quantitative research. Key concepts were categorized into nursing, environment, health, and humans, which are the paradigms of nursing, while papers in all other categories were categorized as etc. Most themes of research were based on social psychological aspects of the health domain and the human domain. Among the eight mediative research studies, seven focused on postnatal married immigrant women and the remaining one focused on postnatal married immigrant women and infants. In the categorized research planning quantitative research took larger part than qualitative research and in quantitative research descriptive study took larger part than experimental research. In the case of experimental research, studies usually focused on married immigrant women who had experienced pregnancy and childbirth. Overall, the results indicated that development and provision of new nursing mediation programs are needed, not only for married immigrant women, but also for their families.

  • Issues on climate change we are facing, such as global warming, are very important as it affects our lives directly. To overcome this, efforts to reduce greenhouse gases emissions (e.g., carbon dioxide) are necessary and these efforts should be based on our integrated understanding of carbon cycle. The purpose of this study is to examine the research trend on carbon cycle education and to suggest the value and direction of carbon cycle education for students who will be citizens of the future. We analyzed 52 carbon cycle education related studies collected from academic research databases (RISS, KCI, ERIC, Google Scholar, and others). As a result, we conclude that resources are still limited and more researches on verification and utilization of developed program, development of accurate and comprehensive tools for students' recognition and level assessment, developing educational model or teacher professional development, providing more appropriate curriculum resources, and the use of various topics or materials for carbon cycle education are necessary. Students' comprehensive understanding of the carbon cycle is important to actively react to the changes in the global environment. Therefore, to support such learning opportunities, resources that can be connected to students' daily experiences to improve students' understanding of carbon cycle and replace misconceptions based on the verification of existing programs should be provided in the classroom as well as the curriculum. In addition, sufficient exemplary cases in carbon cycle education including various materials and topics should be provided through professional development to support teachers teaching strategies with carbon cycle.
