Due to the unprecedented worldwide pandemic of the new Covid-19 infection, business trends of companies have changed significantly. Therefore, it is strongly required to monitor the rapid changes of innovation trends to design and plan future businesses. Since the pandemic, many studies have attempted to analyze business changes, but they are limited to specific industries and are insufficient in terms of data objectivity. In response, this study aims to analyze business trends after Covid-19 using Crunchbase, a global startup data. The data is collected and preprocessed every two years from 2018 to 2021 to compare the business trends. To capture the major trends, a network analysis is conducted for the industry groups and industry information based on the co-occurrence. To analyze the minor trends, LDA-based topic modelling and word2vec-based clustering is used. As a result, e-commerce, education, delivery, game and entertainment industries are promising based on their technological advances, showing extension and diversification of industry boundaries as well as digitalization and servitization of business contents. This study is expected to help venture capitalists and entrepreneurs to understand the rapid changes under the impact of Covid-19 and to make right decisions for the future.

This study aims to present a more systematic and developmental research direction by classifying animal-mediation related research trends published in Korea. We analyzed the research trends of 68 domestic animal-mediation programs published in 26 journals over the past 24 years under the premise of the necessity of animal-assisted therapy, which considered a very effective intervention method in the practice areas of various subjects. Therefore, this study examines the year of publication of animal-mediation related research conducted in various academic fields from 1998 to 2022, research data sources, characteristics of research subjects, types of interventions and research topics, research design and intervention sessions, intervention methods, and ethical consideration statements. The results of this study are as follows: First, in the source of research and research trends by year, the number of papers published in animal-related societies was the highest at 34 (50%); the number of studies has been steadily increasing since the mid-2000s. Second, regarding research trends by subject, 45 (66%) were general subjects, 23 (34%) were medically diagnosed, 60 (88%) were selected through pre-evaluation, and 8 (12%) were requested. Third, regarding research trends by method, 27 (40%) of the pretests were conducted before and after the experiment-control group, and only 3 (4%) of the 68 papers were examined later. Fourth, regarding research trends by content, depression (25%) was the most frequently applied variable, and regarding intervention sessions, 53 (78%) were less than 12 sessions. Fifth, regarding research trends and ethical consideration statements by treatment approach method, 58 cases (85%) of individual treatment approaches and 10 cases (15%) of intervention approaches integrated with individual treatment approaches, and 23 cases (34%) of studies with ethical consideration statements or the Institutional Review Board's (IRB) approval. Based on the study results, the implications and research directions of animal-assisted therapy related research are discussed.

The purpose of this study is to identify rural research topics, differences in research topics over time, and key mediators through the analysis of academic research trends using topic modeling. This study analyzed a total of 1,183 articles published in the Journal of Rural Planning and Rural Society over a 23-year period (2000-2022). We categorized rural research topics into 30, examined the proportion of research in each topic, and identified major changes in research topics over time. We also identified key words that mediate between research topics. The study found that, first, rural research trends can be categorized into five types (resources and utilization, area/space, people, ecosystem/environment, and tourism), with area/space being the most studied. Subtopics include rural amenities, rural disappearance/village miniaturization, and rural landscape management. Second, the research topics for each period were different. In the first period(2003-2007), the main research topics were rural amenities and Agricultural production- based climate vulnerability assessment. In the second period(2008-2012), the main research topics were Rural extinction and village depopulation, and rural landscape management, and in the third period(2013-2017), the main research topics were rural sixth industrialization and rural ecotourism. In the fourth period(2018-2022), rural development planning and rural life services(life SOC) were the main research topics. The significance of this study is that it extends the existing method of analyzing research trends and provides basic data to enhance comprehensive insights and understanding of rural research.

The objective of this study was to estimate genetic trend on racing time of Thoroughbred racehorses in Korea, using a total of 209,725 racing records of 9,934 racehorses collection from January, 1990 to December, 2006. Phenotypic trends for all distances were negative at a rate of －0.148, －0.137, －0.137 and －0.139 second per race year for distances of 1,000m, 1,400m less than, 1,700m more than and overall dataset, respectively. Environmental trends were similar to phenotypic ones in all distances and trends in permanent environmental and jockey effects by race year were not found. Average genetic improvements for racing time were －0.037 and －0.030 second per race year at the 1,000m and overall dataset, respectively, which is low. But Genetic trends were decreased consistently. There is need to establish the genetic improvement program for quality of racehorses.

The purpose of this study is to compare research trends in the information and communication technology (ICT) field between North and South Korea and analyze the differences by using data mining. Frequency analysis, clustering, and network analysis were performed using keywords from seven South Korean and two North Korean ICT academic journals published for five years (2015-2019). In the case of South Korea (S. Korea), the frequency of research on image processing and wireless communication was high at 16.7% and 16.3%, respectively. North Korea (N. Korea) had a high frequency of research, in the order of 18.2% for image processing, 16.9% for computer/Internet applications/security, and 16.4% for industrial technology. N. Korea's natural language processing (NLP) sector was 11.9%, far higher than S. Korea's 0.7 percent. Student education is a unique subject that is not clustered in S. Korea. In order to promote exchanges between the two Koreas in the ICT field, the following specific policies are proposed. Joint research will be easily possible in the image processing sector, with the highest research rate in both Koreas. Technical cooperation of medical images is required. If S. Korea's high-quality image source is provided free of charge to N. Korea, research materials can be enriched. In the field of NLP, it calls for proposing exchanges such as holding a Korean language information conference, developing a Korean computer operating system. The field of student education encourages support for remote education contents and management know-how, as well as joint research on student remote evaluation.
