The purpose of this study is to investigate what kind of research fields are preferred by the researcher of the Korean Physical Education Society using the Mecab-ko morpheme analysis and whether there are differences in the interests of researchers between the humanities and social sciences and natural sciences. A total of the data collected for this study are 5,014 papers published online from March 2002 to March 2017 in the Korean Journal of Physical Education was collected. In this study, we used Mecab-ko morpheme analyzer to extract the keyword from the collected documents. As a result, the study found that the number of papers published in KAHPERD appeared to be decreasing. It was also that the main concern of researchers in KAHPERD toward was leisure, live sports and health were relatively higher than the improvement of performance. The research subjects that were interested in the research were women, middle-aged and elderly. The study found that researchers in the humanities and social sciences have shown interest in both traditional research and social interests, while researchers in the natural sciences have shown an interest in a deeper study of traditional research. In conclusion, in order to realize the revitalization of sports convergence research, it is necessary to establish standards for the field of study which should focus on the depth and breadth of research.

The purpose of this study is to investigate the perception of academic journals and scholarly events published and operated by the four major academic societies in library and information science (Korean Library and Information Science Society, Korean Society for Library and Information Science, Korean Biblia Society for Library and Information Science, and Korea Society for Information Management). An online survey was carried out to know the members' perceptions of journals' quality, number, review process, publication/distribution, readership, practicality, interdisciplinarity, internationalization, and differentiation. In addition, the reasons for participation and non-participation in scholarly events, the degree of achievement of the purpose, differentiation between scholarly events, and ways to revitalize joint academic conferences were examined. A total of 197 members of the four societies completed the survey. The findings showed that the overall quality of the four journals was good, but they still needed to be improved in the review process, publication and distribution, readership, practicality, and internationalization. Strategies to specialize each journal needed to be considered as well. To revitalize scholarly events, large-scale joint academic conferences can be organized to encourage the participation of researchers and practitioners, considering both academic and social aspects of research and practice. This study mainly reported the results of the online survey. Also, it shed light on the suggestions to improve the academic journals and scholarly events in the field of library and information science based on the findings from the case studies of international academic journals and events as well as the group discussions and feedback from the participants at the joint conferenece held in December 2022.

For effective water quality management, it is necessary to secure reliable water quality information. There are many variables that need to be included in a comprehensive practical monitoring network : representative sampling locations, suitable sampling frequencies, water quality variable selection, and budgetary and logistical constraints are examples, especially sampling location is considered to be the most important issues. Until now, monitoring network design for water quality management was set according to the qualitative judgments, which is a problem of representativeness. In this paper, we propose network design system for optimal water quality monitoring using the scientific statistical techniques. Network design system is made based on the SAS program of version 9.2 and configured with simple input system and user friendly outputs considering the convenience of users. It applies to Excel data format for ease to use and all data of sampling location is distinguished to sheet base. In this system, time plots, dendrogram, and scatter plots are shown as follows: Time plots of water quality variables are graphed for identifying variables to classify sampling locations significantly. Similarities of sampling locations are calculated using euclidean distances of principal component variables and dimension coordinate of multidimensional scaling method are calculated and dendrogram by clustering analysis is represented and used for users to choose an appropriate number of clusters. Scatter plots of principle component variables are shown for clustering information with sampling locations and representative location.

Since the pharmaceutical industry is a research oriented sector, the research and development capability based on the qualified R&D manpower is one of the key success factors to strengthen the national competitiveness. Securing the appropriate number of researcher needed for the research activities in these fields is an important precondition for a government policy that aims for a strongly knowledge-intensive the pharmaceutical industry growth. In this study, we conducted and analyzed a delphi survey of the experts(the principal investigators) with expertise in these pharmaceutical research areas. The current and future requirements for the pharmaceutical science research personnel including medical doctors have been evaluated, extending the year 2017. The results of this study can be summarized as follows; First, in 2007 the field of pharmaceutical R&D personnel is currently under-supplied as many as about 5,600 people. The rate of under-supplied is about 18.1%. Second, in 2017 the evaluation shows that the R&D personnel in this field will be more severely under-supplied as many as 13,500 people. The rate of under-supplied will be about 28.6%. As a result, the confrontation of demand and supply evaluation shows that, in general, severe shortages of R&D manpower in the field of pharmaceutical will result if there are not adequate manpower policy adjustment.

From 1905 to 1910 when the deepening national and educational crisis existed, the Korean intellectuals established many educational associations and published many academic journals. In this study, the researcher investigated 9 academic journals which had 132 books published by these educational associations in Korea during the Modern Educational Period (1876${\sim}$1910). The results of this study were summarized as follows : (1) The contents of journals mainly consisted of the Korean history and geography for the purpose of increasing Korean people's identification. And also the journal articles dealt with the western political and economic systems. In addition to these contents, the journals included many scientific studies which were aimed at educating the ordinary Korean people. (2) The scientific articles from these journals were mainly composed of earth science and biology including physiology, while the number of articles for physics and chemistry was less. (3) These scientific articles were published by the same writer in a series .However, the academic level of these was like a school textbook. Based on the results of the data analysis, it is believed that these journal articles possibly were used as a school textbook for science education.

When designing network processors or implementing network equipments such as routers are implemented, IP lookup operations cause the major impact on their performance. As the organization of the IP address becomes simpler, the speed of the IP lookup operations can go faster. However, since the efficient management of IP address is inevitable due to the increasing number of network users, the address organization should become more complex. Therefore, for both IPv4(IP version 4) and IPv6(IP version 6), it is the essential fact that IP lookup operations are difficult and tedious. Lots of researcher for improving the performance of IP lookups have been presented, but the good solution has not been came out. Software approach alleviates the memory usage, but at the same time it si slow in terms of searching speed when performing an IP lookup. Hardware approach, on the other hand, is fast, however, it has disadvantages of producing hardware overheads and high memory usage. In this paper, conventional researches on IP lookups are shown and their advantages and disadvantages are explained. In addition, by mixing two representative structures, a new hybrid parallel architecture for fast IP lookups is proposed. The performance evaluation result shows that the proposed architecture provides better performance and lesser memory usage.

Many researches have recently discussed about the film thickness as a good substitute or supplement for VMA or other volumetric criteria in the design procedure. Some researchers have not only proposed the specific number for the recommended film thickness, but also introduced the new calculation procedures or concepts. Each model (index model and the virtual model) has its own advantages and disadvantages in terms of the ability to account for the volumetric properties of the mixture. In this paper, the modified virtual model was proposed to combine advantages from both models. However, it cannot be disregarded the way to determine the appropriate particle shape factors for different sources and sizes of aggregates. In order to evaluate the different calculation methods, mixtures with two aggregate sources and eight gradations were designed based on the dominant aggregate size range (DASR) porosity concept. Superpave indirect tensile test (IDT) and asphalt pavement analyzer (AEA) test were used to describe the performance of mixtures. Test results indicated that the virtual model, which is the same to the modified virtual model for sphere 1:1 case, is better than the conventional standard model to define the range of the film thickness to have better performance of asphalt mixtures.

In line with the recent wave of the 4th Industrial Revolution, the environment for defense R&D is transforming into a center of high-tech military technology. In particular, developed countries are strengthening control of technology exports and technology transfer to protect advanced defense science and technology. For this reason, the budget demand for securing the ability to develop independently high-tech weapons and core technologies suitable for the future battlefield environment is increasing, and increasing efficiency in R&D investment has been highlighted for efficient distribution of limited budgets. This study examined the efficiency of the defense basic R&D project using the non-parametric approach, DEA. The R&D budget, R&D researcher, and R&D period were selected as the input variables, and the number of papers and patents were used as output variables. The efficiency of basic R&D projects was analyzed through CCR, BCC models, and SE. Lastly, based on the efficiency measurements, the cause of the inefficiency of R&D projects was suggested, and ways to improve efficiency were suggested. This study is expected to be used as useful information that can be applied to project performance management through efficiency analysis of basic defense R&D projects and be reflected in the project planning stage through feedback.
