While the quantitative results of research on emotional labor that has been studied in Korea has never been minimal, most of the researches that have been conducted are limited to generalization by empirical analysis studies limited to single industry cases. A more integrated approach is needed in addition to quantitative research methods in order to research results that can be generalized when the importance and interest in emotional labor is increasing. Therefore, this study analyzed in-depth 112 articles published in the field of management in Korea, which were searched under the keyword emotional labor, using KCI from 2008 to 2018. To this end, the research trends of emotional labor, such as the concept, and the method of analysis, were reviewed from various aspects and presented future research directions. This research result attempted to contribute not only to academic contribution to emotional labor but also to the expansion or integration of the application area to the internal mechanisms of emotional labor.

The purpose of this study is to explore the research trends and knowledge structures of 『Journal of Elementary Mathematics Education in Korea』 by applying the keyword network analysis. To do this, we analyzed the frequency of the occurrence of keywords in the journal and conducted keyword network analysis using the Krkwic program and NodeXL program. The results of the analysis are as follows. Firstly, 749 keywords were extracted from keyword cleansing process and 48 keywords, including mathematics curriculum, mathematics textbooks, school mathematics, mathematical problem solving, mathematically gifted student, etc. appeared more than five times. Secondly, the keyword network analysis showed that the keywords-mathematics textbooks, school mathematics, mathematical problem solving, mathematical communications-have high connection centrality. Finally, we provided the limitations of this study and suggested future research.

This study aimed at understanding trends of living lab studies and deriving implications for directions of the studies by utilizing text mining. The study included network analysis and topic modelling based on keywords and abstracts from total 166 thesis published between 2011 and November 2019. Centrality analysis showed that living lab studies had been conducted focusing on keywords like innovation, society, technology, development, user and so on. From the topic modelling, 5 topics such as "regional innovation and user support", "social policy program of government", "smart city platform building", "technology innovation model of company" and "participation in system transformation" were extracted. Since the foundation of KNoLL in 2017, the diversification of living lab study subjects has been made. Quantitative analysis using text mining provides useful results for development of living lab studies.

Purpose: The purpose of this study was to analyze research trends related to young children with developmental delays through keyword network analysis. Method: To do this, this study investigated the tendency of articles published in KCI journals by year and conducted network analysis on the keyword appeared in studies. Results: First, 82 studies related to young children with developmental delays were published by 2018 since 1998, and most of them published in the journal of Korean Journal of Early Childhood Special Education. Secondly, the most frequently appearing main keywords were identified as 'young children with developmental delays', and the frequency of keywords such as 'social interaction', 'inclusive education', 'problem behaviors', 'positive behavior support' was also high in order. Third, the result of linkage-oriented analysis showed that 'social interaction' and 'inclusive education' were identified as important keywords. Conclusion: This study is meaningful in that the research trends of domestic journals related to young children with developmental delays were examined through the keyword network analysis.

This study aims to diagnose research trends and to deduct implications from meta analysis of entrepreneurship studies in the Asia Pacific Journal of Small Business (APJSB), one of the most well-known academic journals in management and entrepreneurship field in Korea. Frequency and crossover analysis are executed in multi-dimensions by time period, topic, author, research level, data, and methodology by complete enumeration of every published paper for 40 years in APJSB which included core terms of entrepreneurship in its title, abstract, or keywords. From objective and quantitative schematization of research trends and characteristics of entrepreneurship studies, novel improvement plans which are highly applicable in research fields are suggested such as diversification of studies from ecosystem perspective, identification of authors, and standardized system of extended abstract of research papers. Implications and suggestions derived from the results propose future research directions and tasks when entrepreneurship studies have been rapidly increased. Furthermore, the innovation plans of management system of journals and papers are expected to contribute promotion of entire studies by significantly reducing trial and error, and inefficiency in research process.
