The purpose of this study was to analyze recent research trends of mathematics textbooks to provide implications for textbook research and development. For this purpose, 90 out of 1121 research papers published between 2006 and 2011 in seven prestigious domestic journals were selected. The papers dealing with only Korean mathematics textbooks were analyzed by school levels (i.e., elementary or secondary), mathematics content areas, analytic methods, and implications. The papers comparing our mathematics textbooks with foreign counterparts were analyzed by reasons for the comparison, school levels, subjects for analysis, and implications. The results of this study urge us to pay more attention to secondary mathematics textbooks, least studied content areas, and various but inconsistent analytic methods. This paper also suggests close connections between textbook analysis and textbook development.

The purpose of this study was to perform a content analysis on 62 domestic and international journals from 1998 to 2017, in order to review research trends in music and people with visual impairments. The framework of the content analysis was based on the year of publication, field of journal, research method, type of research, research subject, participants' age, and factors of impairment. The results showed that both domestic and international journals have rapidly increased in the last 10 years, and have expanded into the fields of education and therapy. In the research method, survey research was conducted much more frequently in domestic journals, while both qualitative and experimental research were employed on a roughly even basis in international journals. With respect to the type and subject of research, music perception and recent trends on the subject of musical interest and aptitude took up the majority of domestic journals, while international journals focused on music intervention, music perception and cognition with musical influences and experiences. The participants in both domestic and international journals were children, adolescents and adults, while the elderly were not observed. In the factors of impairment, research on people with total blindness or low vision were conducted frequently, but those with adventitious vision loss or multiple impairments were rarely performed. This study could be meaningful to suggest the direction of further studies, through the investigation of research trends in music and people with visual impairments.

Among non-timber forest products, Tricholoma matsutake is a high value added item. Many countries, including Korea, China, and Japan, are doing research and technology development to increase artificial cultivation and productivity. However, the production of T. matsutake is on the decline due to global warming, abnormal temperatures and pine tree pest problems. Therefore, it is necessary to identify trends in domestic and foreign research on T. matsutake, respond to preemptive research and development to preserve the genetic resources of T. matsutake and increase its productivity. Based on the correlation between keywords in the high frequency keywords, it was observed that microbial clusters of T. matsutake are mainly found in Korea. The main focus in China has been the pharmacology studies on the ingredients of T. matsutake. The main focus in Japan has been on preserving the genetic diversity and species of T. matsutake. Thus, future domestic studies of T. matsutake will require pharmacological studies on the ingredients of T. matsutake and on its genetic diversity and species conservation. In addition, unlike China and Japan, genetic keywords did not appear in Korea at high frequency. Therefore, Korea will have to proceed with research using modern molecular biology techniques.

This study examines research trends in the dissertations and theses on fashion illustration, as part of the necessity of the enlargement of this field into different areas and the importance of fashion research that will in the future. Currently, there are efforts to find the state of pervasive trends in thesis or that of dissertations in this area to help deter existing studies from producing mutually supplementary and constructive results. This also includes research that may have been overlapped in part or biased toward particular fields. This study is to solidify the research trend in papers and dissertations on fashion illustration in fields unexamined to suggest some of the right direction for research and development in fashion illustration. The selected data involved papers and dissertations published between 1990 and April 2009 by domestic graduate schools. To understand the research trend by item, descriptive statistics are utilized to acquire statistical data on the frequency and percentage in the creation of graphs. The findings of the study are as follows: There has been a steady increase in the rates of the theses and dissertations in this field in yearly domestic research fashion trends in illustration since 2002. In terms of the annual trend by the type of research, the number of the theses and dissertations on the production of works is larger than that of theoretical ones. This indicates that more attention should be given to theoretical research in this area. In regard to research themes and methods, many theses and dissertations were included with the production of works that showed a need to diversify the scope of research.

In this study, we collected and analyzed domestic and international studies related to watersheds in the forest sector. Keyword co-occurrence analysis was conducted using the VOSviewer program to identify the research areas of domestic and international studies and the network structure to compare research trends. As a result, the number of research articles in international watershed-related studies showed an overall increasing trend, and the research areas were diverse and located close to each other, indicating that many convergence studies were conducted. On the other hand, the number of papers in domestic watershed-related studies seems to have stagnated overall from the past to the present, and the research areas are mainly focused on forest disasters and hydrology, with limited interdisciplinary convergence studies. In addition, in both domestic and international studies, watersheds are currently mentioned as research sites rather than management or analysis units in the forest sector. It is important to actively promote interdisciplinary research in Korea to provide a scientific and balanced basis for watershed-level forest management planning.

Purpose - This study examines previous research on organizational silence for several decades since the concept of organizational silence was firstly suggested in 2000. In this study, based on previous studies on organizational silence published in domestic and international journals from 2010 to 2022, research trends were analyzed, issues were derived, and future research was suggested. Design/methodolgy/approach - The authors searched relevant keywords such as organizational silence, employee silence, employee voice and so on in the domestic as well as international academic database. 63 domestic papers were found, and based on these articles, we analyzed the research trends. Findings - Similar variables were proven with only different contextual samples without any originality in the theoretical perspective. Moreover, studies on the causal relationship between each type of organizational silence and the occurrence of organizational silence over time were also insufficient. In addition, because research on public organizations was limited to police officers and public officials, future research is needed to investigate more different organizational situations. Furthermore, other variables such as personal characteristics and leadership factors were also relatively unexplored. Based on these limitations, future research is needed to consider more diverse demographics, Korean cultural factors, organizational characteristics, and the patterns changes in time. Research implications or Originality - This study suggests limitations as well as future directions by summarizing the previous research on organizational silence which is an emerging issue in global societies and the organizational management filed.

The purpose of this study is to report the research trends of Korean medicine treatment for alopecia areata. We investigated the studies on Korean medicine treatments for alopecia areata via searching 4 web databases of Korea. 13 papers were selected, and we classified them according to publication year, published journals, the types of study, research subject, the methods of treatment, confirmation of recurrence, methods of evaluation, and institutional review board(IRB). We analyzed a total of 13 clinical studies of Korean medicine on alopecia areata based on various criteria and reviewed the research trends. Based on this, we suggested points to be improved and supplemented when conducting clinical research on alopecia areata in the future. Clinical studies on alopecia areata started to be published in 2001, and acupuncture, pharmacopuncture, herbal medicines, etc. were used as treatment methods for alopecia areata. Most of the clinical studies on alopecia areata were case studies, so it is thought that various types of clinical studies are needed. In addition, it is necessary to confirm the recurrence of alopecia areata and to improve the awareness of research ethics.
