The purpose of this study was to explore research trends in sleep from infancy through to adolescence. To achieve this, an examination was conducted of sleep research published in Korea based on the publication year, developmental stages of the study participants, research designs, measurement tools, and research topics. A total of 362 academic journal articles and theses/dissertations published in Korea up until 2023 were selected. In terms of publication year, the first study was conducted in 1967 and the field became more active from 2010 onwards. The age group studied the most was adolescents, with cross-sectional research being the most common study design. Regarding sleep measurement tools, most scales measuring sleep in infants, preschoolers, children, and adolescents were developed abroad, then adapted or validated in Korea, or were modifications of adult scales tailored for specific studies. Lastly, in terms of research topics, the most common focus was the relationship between sleep and developmental characteristics, particularly its effects on emotional development. Based on these results, future research could focus on developing sleep-related intervention programs and measurement tools.

This paper aims to understand and analyze the mega-trends such as trends towards larger vessels due to an increasing trade volume, accordingly fewer port calls, strategic alliances and M&A Increasing degree of concentration through M&A activities in shipping industry results in a decreasing number of shipping finns with an increasing share in the world shipping capacity. But competition is strongly increasing on main trunk routes. Therefore, shipping concentration directly leads to further concentration of port traffic in fewer and larger ports with an increasing competition among neighboring ports.

With the development of artificial intelligence (AI) and 5G technology, an ecosystem of digital content is gradually becoming intelligent, immersive, and convergent. However, there is not enough ultra-realistic content for the ecosystem. For ultra-realistic content services, creative content technologies using AI are being developed. This paper introduces the trends in and prospects of creative content technologies such as 3D content creation, digital holography, image-based motion recognition, content analysis/understanding/searching, sport AI, and content distribution.

In this paper some of the important trends in the spacecraft technology development have been discussed. Trends of higher satellite radiate power, which involves higher TWTA powers and antenna reconfiguration, and Ka-band (30/20 G $H_{z}$) utilization are discussed. Evolutionary trends in satellite communications in general have demonstrated immense potential for meeting the evolving nees and challenges regarding provision of global telecommunications during over past two decades. Their promise for the coming decades as we enter the 21st century may far surpass our imagination. The expansion of fixed satellite service market will depend upon more inelligent spacecraft and a network of more cost effective small earth stations. Radiation hardened microwave analog technologies and high speed digital technologies are getting ready to meet the challenge posed by future markets. At present commercial satellite communications are going through a trasition period.d.

The purpose of this study is to investigate research trends in the knitwear fashion field and suggest future directions for fashion businesses and research. Research trends in the knitwear fashion field were investigated. A total of 134 articles on knitwear fashion field among 4027 published in five journals - Journal of the Korean Society of Knit Design, Journal of the Korean Society of Costume Culture, Journal of the Korean Society of Clothing and Textiles, Journal of the Korean Society of Fashion & Costume, and Journal of the Korean Society of Costume - from 2001 to 2010 were analyzed. Most (32.84%) of articles related to knitwear fashion were published in Journal of the Korean Society of Knit Design. The knitwear fashion field was divided into fashion design, clothing construction, textile science, fashion marketing, and history of costume. The majority (43.28%) were on the research topic of fashion design, followed by textile science, clothing construction, fashion marketing, history of costume. From 2001 to 2010, the number of papers relating to knitwear fashion increased from year to year. The further development of the knitwear fashion field can be expected in the future.

The purpose of the study was to analyze trends of the previous interventions based studies in Korea to improve behavior problems of the children with EBD in order to suggest the research development and trends of future behavior intervention program as their behavior coping strategies. Therefore, it was analyzed 50 papers related to interventions of behaviors problems, published at the professional EBD journal from 2005 to 2009. The result suggested effective intervention factors, strategies, program & intervention trends, based on the results by factors. Previous researches in the study was comparatively analyzed by factors, such as the number, gender, age, and grade of subjects, and strategies, deliever, place of the intervention. The result of the study was analyzed the Previous researches based on the research subjects, research methods(subjects, research design, intervention delievers, intervention places, and intervention periods) and the type of intervention strategies included research procedures. The study results provided the foundation of the future intervention methods and the related program developments.

In this study, social network analysis was performed to compare and analyze changes in domestic tourism trends before and after the outbreak of COVID-19 in a situation where the damage to the tourism industry due to COVID-19 is increasing. Using Textom, a big data analysis service, data were collected using the keywords "travel destination" and "travel trend" based on the collection period of 2019 and 2020, when the epidemic spread to the world and became chaotic. After extracting a total of 80 key words through text mining, centrality was analyzed using NetDraw of Ucinet6, and clustered into 4 groups through CONCOR analysis. Through this, we compared and analyzed changes in domestic tourism trends before and after the outbreak of COVID-19, and it is judged to provide basic data for tourism marketing strategies and tourism product development in the post-COVID-19.
