In an attempt to evaluate the current research status of genetically modified (GM) plants, the scientific research publications in Korea as well as in international SCI journals were screened. About 190 research articles related to the development of GM plants were searched from 10 different domestic journals in the last 12 years (Jan. 1990 to Sept. 2002), The researches in 65 articles were carried out with tobacco plant, 20 with rice, 19 with potatoes, and less then 9 articles from each other plant species, respectively, In total, 38 different plant species were being subjected for the development of GM plants. In particular, there was only one article for each major staple grains such as wheat, barley, soybean, and maize. In more than 47% of total published articles, scientists mainly focused on the basic research such as developing transformation system (46 articles), gene expression study in transgenic plants (34), and vector constructions (10). In addition, 28 articles which main authors are Korean scientists were searched from 11 different international SCI journals. Again, major plants for GM research were tobacco (10) and rice (7). More than 50% of published articles were focused on the basic research, gene expression study with transgenic plants (16). The publications on the research of disease-resistant plants were 7 articles, 3 for the development of stress-resistant and 2 for the herbicide-resistant plants, respectively. It is believed that the last 10 year's investment through government organizations has just strengthen the capacity for the next big stride on agricultural biotechnology in Korea.

This study aims to analyze trends of advanced research of "Muyedobotongji". The conclusions are as following in these. First, the number of theses related with "Muyedobotongji" is 47 in total including 29 master's theses and 18 doctor's theses. The sports science comprises the largest proportion of study including 23 master's degree and 12 doctor's degree. Besides sports science field, "Muyedobotongji" is analyzed in various study fields such as library and information, engineering, science of art and culture contents. In master's theses, They focused on practical ways of "Muyedobotongji". But "Muyedobotongji" is conducted by perspective of the humanities in doctor's theses. Second, There are 72 theses related with "Muyedobotongji" in scientific journal. Regarding these in detail, there are 35 theses in sports science, 12 theses in Korean history, 7 theses in martial arts, 5 theses in dance studies, 4 these in Korean studies, 2 theses in Chinse studies, 2 theses in art history, 1 these in Japanese literature and 1 thesis in military science. This fact helps us understand "Muyedobotongji" is studied actively in sports science field. Third, the future research directions of "Muyedobotongji" Should be considered in 3 categories. first, it needs to do interdisciplinary fusion research. Through this, it can complement insufficient parts of existing researches. Second, it needs to make standard Key words. The unified Key words are able to use communicating in different field of scientific journals without confusing. Third It needs to build data bases which are applied to martial art areas. It can provide chances for both Korean martial arts and "Muyedobotongji" to be practiced in culture contents.

The purpose of this study is to analyze the research trends of lifelong education workers, based on research articles related to lifelong education workers published in domestic journals from 2001 to 2021, and to provide basic data for future lifelong education workers research. In order to achieve these research objectives, research trends of 40 research articles related to lifelong education workers published in domestic journals were analyzed by research subject and research method, and the detailed research conclusions are as follows. First, as a result of the analysis by characteristics of researches related to lifelong education workers, it has been continuously increasing since 2001 out of a total of 40 articles by year. From 2001 to 2005, there were 2, 8 from 2006 to 2010, 10 from 2011 to 2015, and 20 from 2016 to 2021. By major publication, there were a total of 20 publications, including 8 Lifelong Education Studies, 5 Lifelong Learning Society, 4 Andragogy Today, and 3 HRD Studies, and 20 articles were published in non-mainstream journals. Second, as a result of the analysis of each study subject, there were 20 lifelong education history, 16 lifelong education managers, and 4 others. Third, as a result of analysis by research method, quantitative research was most used, followed by qualitative research, literature research, and mixed research. In future research, many research topics such as analysis of various policies related to lifelong education workers and exploration of development plans should be carried out.

The scientific research results on the Korean traditional non-alcoholic beverages published in the literatures were reviewed. A total of 79 research papers were collected; 11 papers were on green tea, 38 on tea analog, 3 on rice tea, 4 on roasted cereal powder, 9 on malt saccharified rice beverage, 1 on ginger-fruit drink, 10 on fruits drink and 5 papers on others. Most of the researches were concerned to the chemical composition and processing conditions. More researches are needed on the quality requirements of the ingredients, the keeping qualify of the products and the industrialization of the traditional processing methods.

This study is to represent the research trends of the resource organization in Korea through the analysis of 607 papers related with resource organization in 4,015 papers on journals of 6 library & information science societies from 1970 through 2010. The results of this study are as follows. The average yearly papers in the case of academic journals published 14.8 pieces. The year published the largest number of papers: 2005 and 2009. The order of the number of papers by the domain of resource organization: cataloging, classification, indexing and abstracting, metadata, subject analysis. And the research on basic principle or theory in the resource organization showed insufficient. The research on KDC classification, cataloging rule, metadata element has are usually presented for improvements. But most of the research is not empirical analysis or objective assessment but subjective judgments of the researchers.

UWB signal with high resolution capability can be used to estimate ranging and positioning in wireless personal area networks. The clock frequency differences of nodes have serious affects on asynchronous ranging methods to estimate locations of mobile nodes. The specification of high rate UWB describes successive TWR method with the estimation of a relative clock frequency offset. In this paper, we complete the ranging equations using relative frequency offset and time information, and propose a method to estimate the exact frequency offsets. We evaluate the ranging algorithms with simulation. The results show that the performances of the algorithms using frequency offsets are very close without noise. But, at noise environment, the method of exact frequency offsets shows better performance than that of relative frequency offsets.

The purpose of the present study was to review psychological studies which have appeared in the "Journal of the Korean Gerontological Society". All told, 130 psychological papers have published for the last 30 years. Nineteen studies appeared in the 1980's, among which were 14 empirical ones and the remainders were review papers. In the 1990's were 51 papers published, and 49 ones were empirical and the rest of 2 literature review ones. In the 2000's did 56 papers appear, among which 56 ones were empirical and the rest of 4 literature review or theoretical ones. Research topics mainly examined about the aged were about mental health, life satisfaction and leasure, parent care and family relations, developmental change in cognition, and the old age general. After review of research trends for the last three decades, findings on each of research topics were examined. Finally, some limitations on the previous studies and future research directions were mentioned.
