  • With the rise of epigraphy and textology, and the emerge of many famous outstanding clerical script masters, Qing Dynasty becomes another important innovation period in the development of the clerical script. Jin Nong and Yi Bingshou are two important clerical script masters in the Qing Dynasty. Thus, researches on the courses of their careers as well as a comparative study between these two calligraphers, Jin Nong and Yi Bing, are specially important. The comparative study of Jinnong and Yibingshou's clerical script is a relatively new subject, which is entered from the angel of comparative perspective between their clerical scripts works. Through an in-depth research on different inheritance routes, which are origin from Han Dynasty clerical scripts, of Jin Nong and Yibingshou, it is found that these two calligraphers are different in innovation of clerical script style, theory of calligraphy and of clerical script practice. This paper focuses on a comparative study of the different clerical theories and clerical script works between Han Dynasty, Jinnong and Yi Bingshou. A comparative study of clerical script works of Jin Nong and Yibingshou in Qing Dynasty provides a more comprehensive and in-depth understanding on these two calligraphers; meanwhile, it provides valuable learning paths for later calligrapher in the field of clerical script, and can be regarded as references in the innovation of the official script style.

  • Purpose: An experiment was conducted to analyze the characteristics of the settlement of soft clay soil in the central region of the west coast of Korea, which has a high silt content and is difficult to predict settlement due to various stress histories. Method: Field experiments were conducted for three cases. The settlement amount of the subsidence plate was measured in each case, and the following conclusions were drawn by analyzing Terzaghi's one-dimensional consolidation settlement amount, both the hyperbolic method and the Asaoka method. Result: The predicted value by Terzaghi was analyzed to be the largest in all cases, and it was predicted to be 111% to 187% larger than the subsidence plate settlement value. That is, the subsidence plate settlement value, which is the amount of settlement of the actual ground, showed a settlement of 53.4~89.9% compared to the predicted value of Terzaghi. Therefore, it was analyzed that the expected settlement of the Terzaghi method in the clay soft ground of the central west coast of Korea is more than the actual settlement. Conclusion: It was analyzed that the Asaoka method and the hyperbolic method presented relatively similar results, and in practice, predicting the settlement amount smaller than the actual settlement amount may cause a risk, so the hyperbola analysis method predicted 6~14% larger than the actual settlement amount can be used as a safety side.

  • The purpose of this study is to critically examine science content and science education from the 'essential-holistic' perspective, in particular, among the core disciplines constituting the teacher education curriculum. In this study, we first, analyzed the definition of the 'essential-holistic' perspective, the philosophical background, and the relationship with the practices in-depth, and then, from the 'essential-holistic' perspective, conducted an inquiry into the essence of science content and science education. The results of this study are as follows: first, according to the 'essential-holistic' perspective, science content is a study that explores the science practices and systematizes the results of that inquiry. Major activities of science content include the establishment and implementation of 'science for teachers' and participation in the development of science curriculum (textbook). Second, science education according to the 'essential-holistic' perspective is a study about in-depth exploration of essential problems in science education phenomena rooted in the science practices and the practice of good teaching. More specifically, science education is a field that carries out work related to inviting, participating, and guiding students to grow into science practices (i.e. initiating into practices). The main activities of science education related to this include activities ranging from the development of the science curriculum (textbook) to teaching and evaluation (recording). In this study, we discussed important tasks to be carried out in the future based on the results of the study.

  • This study is to evaluate the intervention effect using a flowmeter in bag-valve mask skill education. The purpose of this study was to compare the accuracy of bag-valve mask skill between intervention group with flowmeter and control group without flowmeter, understand the improvement effect of skill education of bag-valve mask, and provide basic data to suggest the method of skill education. The total number of subjects of this study was 60, with 30 intervention group and 30 control group. In comparison of the optimal number of normal tidal volume range at pre-test and post-test, the normal range percentages of the intervention group before and after education were 32.8% and 86.7%, respectively, and there was a significant difference(p<0.01). The normal range percentages of the control group before and after education were 20.0% and 34.7%, respectively, and there was a significant difference(p<0.05). To evaluate the factors associated with good performance of bag-valve mask skill of the subjects including the normal range of tidal volume, the logistic regression analysis has been performed, and the significant influential factors were gender(10.305, 1.20-87.98), educational experience of field practice(31.674, 1.25-805.16), and intervention(92.750, 4.58-1879.69). Through this study, it was confirmed that the intervention using flowmeter for the skill education of bag-valve mask was effective, and it is necessary to consider reflecting it in the education of students majoring in emergency medical technology in the future.

  • The purpose of this study is to have college students who took 'University Character Education Using YouTube Videos', which was opened as a liberal arts course in college, directly produce UCC assignments with the theme of personality. Despite the recent paradigm shift in learner-centered education, teacher-centered education still hinders learners' motivation to participate in classes. To solve this problem, a learner-led UCC production process is necessary for the practice of effective learner-centered education. For this purpose, a phenomenological research method was applied. The research participants were 10 students, in-depth interview was used for data collection, and Colaizzi's research method was selected for data analysis. As a result of the analysis, 9 themes, 4 theme clusters, and 2 categories were derived. The results are as follows. First, they recognized that the UCC assignments were a field of maturity, such as practicing the right thoughts and actions, and re-establishing the concept of character. Second, they said that the UCC production process was an opportunity to increase their self-esteem. Third, they showed a more mature personality by recognizing that the UCC assignments became a chance to pay attention to others beyond themselves. Fourth, they had the greatest difficulty in selecting a topic while carrying out the UCC project, and they were experiencing the limitations of high-quality projects due to the technical immaturity of UCC production. Finally, this study was concluded by discussing the educational implications based on the results. These results provide a suggestion that more effective character education can be expected when tasks led by learners will be developed and an interactive arena where students can be shared are provided.

  • The purpose of this paper is to examine the Christian educational understanding of habit formation through the practical field of Christianity called worship. In the Cultural Liturgy series, James Smith criticized the intellectualistic Christian education so far and opened up a completely different level of possibility for Christian education through a unique study on habit formation. He focuses on education through actions, not education through the mind, and deals in depth with the relationship between habits and the body, between habits and knowledge, between habits and meaning systems, and between habits and human formation. Among them, it is emphasized that worship is a major liturgy that forms the identity of the participants through habits. Accepting Smith's position positively, this thesis first deals with the concept and understanding of major thinkers about habit. Second, we will look at habitual knowledge through the body. And lastly, it deals with Christian educational understanding of worship as a place of habit formation. Worship is not a one-time event, but an inseparable relationship with habit in terms of regular body practice. In particular, when we look at worship from the point of view of habits, it can be seen that the accumulation of experiences through bodily activities plays an important role in forming the horizon and background for understanding the world of the worshiper. Therefore, this thesis is meaningful in seeking and reconfirming the Christian educational possibility of worship as a habit formation.

  • The Korean military is preparing for successful manpower reduction using advanced science and technology, in addition to carrying out the initiative of the Defense Innovation 4.0. Accordingly, studies on core technologies related to defense reform have been conducted both internally and externally in the military, and the corresponding results have also been applied. Nevertheless, compared to the development of such technologies, it is considered necessary to have more preparation for the policies related to the operation of the newly introduced equipment. As for the placement of personnel and the organization of time in service (TIS) with respect to the operation of surveillance equipment, there has been a tendency to sustain the conventional practice. Therefore, this study intends to suggest the schemes for facilitating policy improvements in the operation of manpower and security regulations in the field of information for the purpose of introducing a successful next-generation coastal guard system. To do this, the approach of this study was focused on the policies for the operation of the guard system. This is in contrast to previous studies that centered on its equipment and technologies. In addition, how to efficiently operate the guard system was also studied in view of cognitive science by deriving the most efficient time for a person to execute surveillance through the monitor based on the previous studies.

  • The amounts of organic matter present in soil and the rate of soil organic matter (SOM) turnover are influenced by agricultural management practice, such as rotation, tillage, forage plow down direct seeding and manure application. The amount of nutrients released from SOM is highly dependent upon the state of the organic matter. If it contains a large proportion of light fractions (low-density) more nutrients will be available to the glowing crops. However, if it contains mostly heavy fractions (high-density) that are difficult to breakdown, then lesser amounts of nutrients will be available. The state of the SOM and subsequent release of nutrients into the soil can be predicted by NIRS as long as a robust regression equation is developed. The NIRS method is known for its rapidity, convenience, simplicity, accuracy and ability to analyze many constituents at the same time. Our hypothesis is that the NIRS technique allows researchers to investigate fully and in more detail each field for the status of SOM, available moisture and other soil properties in Alberta soils for precision farming in the near future. One hundred thirty one (131) Alberta soils with various levels (low 2-6%, medium 6-10%, and high >10%) of organic matter content and most of dry land soils, including some irrigated soils from Southern Alberta, under various management practices were collected throughout Northern, Central and Southern Alberta. Two depths (0- 15 cm and 15-30 cm) of soils from Northern Alberta were also collected. These air-dried soil samples were ground through 2 mm sieve and scanned using Foss NIR System 6500 with transport module and natural product cell. With particle size above 150 microns only, the “Ludox” method (Meijboom, Hassink and van Noorwijk, Soil Biol. Biochem.27: 1109-1111, 1995) which uses stable silica, was used to fractionate SOM into light, medium and heavy fractions with densities of <1.13, 1.13-1.37 and >1.37 respectively, The SOM fraction with the particle size below 150 microns was discarded because practically, this fraction with very fine particles can't be further separated by wet sieving based on density. Total organic matter content, mechanical texture, ash after 375$^{\circ}C$, and dry matter (DM) were also determined by “standard” soil analysis methods. The NIRS regression equations were developed using Infra-Soft-International (ISI) software, version 3.11.

  • 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.

  • As the importance of R&D increases amid the paradigm of technology hegemony competition, countries around the world are increasing investment in R&D, at the same time, making effrots to portect R&D. Centering to technology-leading countries, such as Korea, the United States and Japan, they reorganize research security regulations to protect national R&D; however, the burden of compliance for researcher and research institutes is still high. Korea enacted the National R&D Innovation Act and the Enforcement Decree of the same Act to establish an integrated and systematic research security support system, but research institutes and researchers still lack understanding and practice of research security. In order to strengthen researcher's research security compliance, this study organized information requirements for each security management area through domestic and foreign research security laws and prior research analysis, and designed research security information requirements items centered on researchers. The designed information requirements are meaningful in that they were designed by considering both the management area and the stage of R&D, focusing on researchers performing R&D in the field. Based on the designed information requirements items, it is expected that systematic security management will be possible at the research site, which will ease the security burden of researchers and improve research security compliance at the research and development site.
