Objective : The purpose of this study was to identify the status and trends of Korean child occupational therapy intervention studies according to the International Classification of Functioning, Disability, and Health, Children and Youth Version (ICF-CY). Methods : In this research, 47 studies on occupational therapy interventions for children that were published between January 2017 and December 2021 in the Journal of Occupational Therapy, registered in the Korea Citation Index, and analyzed the classification of the study type and evidence level to understand the trends. Moreover, intervention objectives and approaches were analyzed on the basis of the ICF-CY. Results : The outcomes of the analysis of the articles published in the Journal of Occupational Therapy were as follows: (1) Level IV was the highest evidence level (53.19%). (2) Among the studies, most (53.7%) included school-age children as subjects. Autism spectrum disorders and developmental delays were the most common diagnoses (14.8%). (3) As for the purpose of intervention according to ICF-CY, activity and participation factors were the most common (48.94%), and a sensory approach was frequently used. Conclusion : This study reviewed articles on occupational therapies for children that were published in the Journal of Occupational Therapy to understand the trends in occupational therapy interventions for children in South Korea. For the development of occupational therapies for children in the future, more qualitative research types and studies on various intervention approaches are needed.

Purpose: As the connection between physical and non-physical structures in cities is expanding and becoming more complex, the risk of complex disaster which causes damage in a complex way is increasing. Preparing for these complex disasters, it is important to preemptively identify and manage disasters that can develop into complex disasters. Therefore, this study analyzes the disaster types studied as complex disasters by analyzing the trends of domestic and international studies related to complex disasters, and presents the direction of complex disaster management in the future. Method: We first established co-occurrence networks between disaster types based on 993 articles related to complex disasters published in disaster-related journals for the last 20 years (2002-2021). Then, through network analysis, domestic and international complex disaster research trends were compared and analyzed. Result: Research on complex disasters related to storm and flood damage, infrastructure failure and fire was high in domestic studies, and it was analyzed that research on complex disasters related to earthquakes and landslides has recently increased. However, in international studies, the proportion of studies on infrastructure failure along with storm and flood damage and earthquake was high, and various types of disasters such as tsunami and drought appeared. Conclusion: The results of this study are expected to increase the understanding of the trends in complex disaster research and provide suggestions of domestic complex disaster research in the future.

The purpose of this study was to analyze the rationale and format of music therapy interventions with patients receiving hospice or palliative care in Korea. Through this analysis, I examined whether the music intervention used was based on a valid rationale and represented the professionalism expected of today's music therapy interventions. A total of 12 studies that met the selection criteria were identified, and the overall characteristics of each study and its format were analyzed. As a result of the analysis, it was confirmed that the rationale for each study and its format were influenced by the author's research field. The analysis also showed that the research on music-based interventions in hospice or palliative care settings was insufficient and involved a mix of professional and nonprofessional interventions. The results of this study suggest that importance of researchers possessing professional competence which requires offering a clear justification for their choice of interventions, music, and instruments. Additionally, these results emphasize the need for further development of evidence-based music therapy approaches in hospice and palliative care settings as the role of music in supporting patients in these environments has gained increasing recognition and validation.

Pre-service science teacher education is important to elaborate the quality of science teaching and learning in schools. Therefore, many pre-service science teacher education researches have been done in Korea. However, almost no research has comprehensively reviewed those literatures including secondary teacher education context. This study reviewed 410 pre-service science teacher education researches in Korea, from 1995 to 2021 published by 17 journals in KCI. The trends were analyzed with respect to the number of article according to period, keyword frequency, and qualitative features. The qualitative features were coded in multiple aspects of pre-service teachers' type, major, subject-matter in research context, research approach, data type, and the number of participants. The results indicate that the number of research articles has increased by about 40 for every 5-year period. JKASE has published most articles, and the diversity of journals has increased since 2010. Keyword frequency revealed that scientific concepts, science teaching efficacy, nature of science, and other teaching and learning contexts were emphasized. In qualitative features, the most frequent pre-service type was secondary in 'general' science context. For research topic, 'pre-service teacher education program' and 'perception and cognitive domain' were the most frequent. Most of the articles have 'analyzed' the phenomena or consequence of educational issue. Most research was conducted with 11 to 30 participants. These patterns of qualitative features have differed according to period, and types of pre-service teacher. Suggestions for the future pre-service science teacher education research topic were explored, such as policy-administrative research, integrated science teacher education, teacher agency, and environmental education.

The purpose of this study is to extract topics from experimental data using the topic modeling methods(LDA, Top2Vec, and BERTopic) and compare the characteristics and differences between these models. The experimental data consist of 55,442 papers published in 85 academic journals in the field of library and information science, which are indexed in the Web of Science(WoS). The experimental process was as follows: The first topic modeling results were obtained using the default parameters for each model, and the second topic modeling results were obtained by setting the same optimal number of topics for each model. In the first stage of topic modeling, LDA, Top2Vec, and BERTopic models generated significantly different numbers of topics(100, 350, and 550, respectively). Top2Vec and BERTopic models seemed to divide the topics approximately three to five times more finely than the LDA model. There were substantial differences among the models in terms of the average and standard deviation of documents per topic. The LDA model assigned many documents to a relatively small number of topics, while the BERTopic model showed the opposite trend. In the second stage of topic modeling, generating the same 25 topics for all models, the Top2Vec model tended to assign more documents on average per topic and showed small deviations between topics, resulting in even distribution of the 25 topics. When comparing the creation of similar topics between models, LDA and Top2Vec models generated 18 similar topics(72%) out of 25. This high percentage suggests that the Top2Vec model is more similar to the LDA model. For a more comprehensive comparison analysis, expert evaluation is necessary to determine whether the documents assigned to each topic in the topic modeling results are thematically accurate.
