The purpose of this study was to investigate the preferred SSI topics of students and teachers in elementary, middle, and high schools. It analyzed the similarity of students' and teachers' preferred SSI topics by school level using the cosine similarity measure. A total of 566 students and 327 teachers from elementary, middle, and high schools participated in the study. Sixty topics were identified and listed in the areas of environment, science and technology, health and medicine, and other social issues based on the literature and SSI programs. Students and teachers were asked to select five of their favorite topics. The data was collected online using SurveyMonkey. The collected data was divided into six groups of students and teachers, and the frequency of topic selection was analyzed within each group. The topic preference similarity was analyzed by calculating vector values based on the frequency of the selected topics and measuring the cosine similarity between students, teachers, and teachers and students by school level. The results are as follows: First, the cosine similarity of SSI Preferred Topics between students' school-level cohorts was higher between middle and high school students (0.982) than between elementary and middle school students (0.651) or between elementary and high school students (0.662). Second, the cosine similarity of SSI Preferred Topics between teachers' school-level cohorts was similar for all comparison groups between elementary, middle, and high school. Third, the SSI topic preference similarity between students and teachers by school level had a higher cosine similarity between the elementary student and teacher cohorts (0.974) than the other school level comparisons, middle school (0.621) or high school (0.645). Access to topics of interest to students in SSI education is strongly associated with motivation and persistence in learning, as well as an enjoyable learning experience and positive attitudes toward learning. Therefore, when designing SSI lessons, it is important to examine topics from the perspective of student interest, especially if the teacher has selected SSI topics that are different from students' preferences. Careful instructional design will be needed to overcome the gap.

The purpose of this study is to see the intellectual structure in the field of veterinary sciences in Korea, using author profiling analysis(APA), a bibliometric approach. Three journals are selected on the basis of citation data, exchanging most citations with Korean Journal of Veterinary. And then, 50 authors who published most articles at selected journals during the given period of time were chosen. The analysis of similarity and dissimilarity among authors by comparing co-word appearance patterns from article title, abstracts, and keywords was made. Authors can be grouped 11 minor clusters under 4 major clusters, depending on their interests in the area of veterinary sciences in Korea. The subjects for each cluster at the veterinary sciences are decided by the matching the keyword, representing author's research interest. As a result, it is possible to figure out the current research trends and the researcher network in the field of veterinary sciences.

There have been a number of studies on ports and they have made great contributions to the development of ports. However, there have been no research that classified and organized the results comprehensively. Therefore, this study aims to analyze the results of studies related to Korean port economics. For the purpose, we carried out a meta-analysis targeting 659 articles published in Journal of Korea Port Economic Association from 1991 to 2010. For the meta-analysis on themes of port economics and methods, the study presented a total of three items to be analysed: First, we analysed characteristics of researchers, discussed themes and identified contents by analysing research methods used for the studies. As a result, port economics have shown great growth in volume and recently, more attentions have been paid to ports along with increase of researchers, and themes and methods of research have been sub-categorized and diversified. Therefore, based on the results of the study, comparative studies should be added.

The purpose of this study is to review research trends and issues of coastal geomorphology in general of Korea, which is divided into two periods; the former and later periods of 1990s when The Korean Geomorphological Society was established. In this study, coastal geomorphology in general refers to the landforms except tidal flats and coastal terraces. The descriptive statistics of research papers published in 5 major geography journals since 1990s were computed and these papers were classified according to their main subjects. The methodology for coastal landform study was analyzed by sub-fields of landform change and sediment analysis. The study of coastal geomorphology in Korea started from around 1970s and has progressed significantly in terms of the scope and the number of papers published since 1990s. There is few paper published in 1990s on coastal geomorphology in general, but so many research has achieved and came to be the major part of coastal geomorphology study since 2000s. Further methodology is necessary for morphodynamics study in the future.

The question how man can perceive the direction of a sound is one of the traditional psychoacoustical problems. Rayleigh already began to investigate this subject in 1870s and kept on interesting himself intermittently throughout his research career. Rayleigh was only concerned with this subject among those of perception of sound and focused more interest on it than any other acoustical problems. At first he insisted on the perception of the direction of a sound by the difference of intensity of a sound in two ears. but was phased in accepting that by the difference of phase of a sound there. Thus he arrived at the modern view that the perception of the sound direction is caused by the difference of intensity in high frequencies and the difference of phase in low frequencies. Rayleigh presented his ability as an excellent experimenter by employing very cautious and ingenious experimental settings and acquired persuasive results by linking the consequences of his mathematical theorization with his experiments.

After COVID-19, the number of individuals participating in delivery platforms has increased. They are using the participation of the delivery platform as a means of creating a new source of income as well as a means of sports and hobbies. This phenomenon is related to a social phenomenon called 'N-jober'. However, there are still few studies examining this phenomenon. Therefore, this study intends to examine the phenomenon of individual participation in delivery platforms and their issues. Text mining was performed on news data from January 2019, when COVID-19 started. As a result, social issues related to the increase in individual participation in delivery platforms were derived into 5 topics(Introduction to the Phenomenon, Characteristics of Participants, Participant's Income and Fees, Characteristics as a Job, Concern about Potential Risks). This study has significance in that it expanded the perspective of academic discussion on delivery platform business to individual participants.
