The objectives of this study is to Systematic literature review of internationalization of SMEs. Due to the economic characteristics of Korea, which depends on economic growth by exports, internationalization has become an essential management activity, not an option for SMEs. As a result, more than 400 studies related to the overseas expansion and internationalization of SMEs have been published in the past 20 years, focusing on major academic journals (such as KCI). Accordingly, the research trends used as advance research in internationalization research were analyzed of SMEs. Research targets were defined as the internationalization of SMEs and searched through 'RISS' (Research Information Sharing Service) as 'internationalization', 'global ', 'export', 'overseas expansion' and 'theory'. The analysis was carried out using a Systematic literature review. It was selected as the 76 studies and According to international research subjects and characteristics, the four areas of internationalization motive, process, outcomes, and support were analyzed. The results of the study confirmed that the most active research is focused on internationalization outcomes. This study could provide a support and the parties concerned in the ecosystem of SMEs in Korea with implications for the SMEs overseas market.

This study aims to look at the application methods of landscape architecture in response to the 4th Industrial Revolution. The results of the analysis of trends in the 4th Industrial Revolution and the subsequent search for application methods to the field of landscape architecture are as follows. First, the 4th Industrial Revolution means innovative change based on digital technology and seeks to create value based on intelligent information technology, and continuous growth is being made through innovation. This requires expertise to collect large amounts of information and creatively rework it, and a strategy to flexibly cope with changes in the times. Second, the status of technological use in response to the 4th Industrial Revolution in the field of landscape architecture is generalizing the establishment of precise analysis results such as survey technology and global mapping using drones, three-dimensional design simulation, and VR. In the field of traditional landscape architecture, efforts are made to obtain accurate fact-finding data on landscape site components. Third, the application methods in the field of landscape science according to the 4th Industrial Revolution in the future are required to supply precision technology and supply programs in the technology sector, and to provide a shared platform. In addition, a systemically standardized process will need to be established for this.

$PM_{2.5}$-bound mercury (PBM) was monitored at weekly intervals for three years (from 2014 to 2016) at an urban (Seoul) and rural site (Baengnyeong) in South Korea. The average PBM concentrations in $PM_{2.5}$ samples over the entire sampling period were $12{\pm}11pg/m^3$ and $36{\pm}34pg/m^3$ for Baengnyeong and Seoul, respectively. Seasonal differences were pronounced, with concentrations being highest in winter due to local meteorological conditions (high gas-particle coefficient due to low temperature and low mixing layer height in winter) as well as seasonal factors, such as coal combustion for heating purposes in China. In Baengnyeong, the significant positive correlation of PBM with $PM_{2.5}$, air pollutants, and heavy metals suggested that coal combustion in China might be the most important source of ambient mercury in Korea. In winter, no correlation of PBM with $PM_{2.5}$, air pollutants, and heavy metals was seen in Seoul. Furthermore, Seoul showed higher $PBM/PM_{2.5}$ and $Pb/PM_{2.5}$ ratios in winter due to the strong atmospheric oxidation-reduction reaction conditions as well as local and regional PBM sources. We conclude that immediate attention must be given to addressing PBM levels in Korea, including considering it as a key component of future air quality monitoring activities and mitigation measures.

In this study, we conducted a study on the win-loss predicton analysis of korean professional baseball by artificial intelligence models. Based on the model, we predicted the winner as well as each team's final rank in the league. Additionally, we developed a website for viewers' understanding. In each game's first, third, and fifth inning, we analyze to select the best model that performs the highest accuracy and minimizes errors. Based on the result, we generate the rankings. We used the predicted data started from May 5, the season's opening day, to August 30, 2020 to generate the rankings. In the games which Kia Tigers did not play, however, we used actual games' results in the data. KNN and AdaBoost selected the most optimized machine learning model. As a result, we observe a decreasing trend of the predicted results' ranking error as the season progresses. The deep learning model recorded 89% of the model accuracy. It provides the same result of decreasing ranking error trends of the predicted results that we observe in the machine learning model. We estimate that this study's result applies to future KBO predictions as well as other fields. We expect broadcasting enhancements by posting the predicted winning percentage per inning which is generated by AI algorism. We expect this will bring new interest to the KBO fans. Furthermore, the prediction generated at each inning would provide insights to teams so that they can analyze data and come up with successful strategies.

In this paper, we analyzed the possibility of utilizing LX-PPS GNSS permanent stations whose antennas are installed on the building rooftop for the purpose of high-precision GNSS positioning services. We picked 15 pairs of adjacent GNSS permanent stations operated by LX-PPS and NGII, and then produced 3-year-long time series using the high-precision data processing software called GIPSY. Patterns and trends of position estimates were compared and analyzed. Horizontal and vertical deviations including the linear velocities coincide with the well-known crustal deformation rates of the Korean peninsula. We also observed almost the same annual or seasonal patterns from those nearby sites. After detrending the linear velocity, the amplitude and phase of annual signals almost perfectly match each other within the baseline length of 2 km. By subtracting seasonal signals, the RMS and standard deviations in LX-PPS PPGR with respect to NGII KANR are about 1, 2, and 5 mm in the north-south, east-west, and vertical directions, respectively. From this analysis it can be concluded that the rooftop-installed LX-PPS sites show similar level of stability and positioning performance comparable to those ground-mounted NGII stations.

This study investigates trends and changes in gender expression in film and animation. It compares how gender, race, and class discrimination that was socially and culturally expressed differently in past and modern media contents. Indiscriminate content appreciation by the "digital native" generation is likely to unconsciously create false stereotypes. In this study, 「Aladdin」(1992) and 「Aladdin」(2019) were analyzed. This study looks at in the characters have changed since the original, which was a 2D animation in 1992, was re-released as a live-action film in 2019. For character analysis, we compare and analyze major characters and find out the differences based on the nine personality types of Enneagram, which define human personality types. As a result, Princess Jasmine's character change was remarkable. In the past, Disney animations had the majority of patriarchal and male-dependent princess characters, but now Disney is aiming for self-directed and independent female characters. Also, scenes that could instill stereotypes of gender, race, and class were changed. Disney's change can be seen as expressing the gender image that the public wants. Analysis of the change in character's personality in these works can be a useful methodology for creating attractive characters for the public.

Objectives The aim of this study was to analyze the trends of researches on oriental medicine treatments for supraspinatus tendinopathy. Methods We used five databases for searching researches; Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, Research Information Sharing Service, PubMed, and China National Knowledge Infrastructure. Only randomized controlled trials suitable for the subject were selected. The methodological quality of included randomized controlled trials (RCTs) was assessed by the Cochrane risk of bias tool. Results Twenty randomized controlled trials were analyzed. There were 9 types of treatment interventions; acupuncture, acupotomy, pharmacopuncture, electroacupuncture, fire needling, warming needle, catgut-embedding therapy, herbal medicine, cupping. The most frequently used treatment intervention was acupuncture and acupotomy. There were 9 outcome measurements including visual analog scale (VAS), Constant-Murley Score (CMS), and range of motion. The most used measurement was VAS. As a result of meta-analysis, acupuncture was more effective than control group in VAS. Additionally, acupotomy was clinically significant compared to control groups in VAS and CMS. Conclusions In this review, we analyzed researches on effectiveness of oriental medicine for supraspinatus tendinopathy. A provisional conclusion can be produced that acupuncture and acupotomy showed beneficial effect to supraspinatus tendinopathy. Although there were some RCT studies, many of them had a high risk of bias, so it is hard to conclude that our study can include overall clinical status. Further well-designed trials are needed.

This overview study of mass culture is based on an academic point of view and based thereon an investigation of mass culture from a psychological standpoint follows. This study reviewed previous studies of mass culture that have been done so far divided into Producer-oriented, Text Decoding-oriented, and Recipient Theory, according to subjects of the study. The studies were also reviewed from the viewpoints of industry, consumer science, education, and developmental psychology. Further, it was discussed how trends and limitations in research were covered according to each viewpoint on mass culture. Based on the analysis, this study aims to promote overall psychological interest in studies of mass culture; to present the necessity of analysis and measurement of emotional experience on mass culture; to increase the roles of industrial and consumer science approaches in terms of planning and culture; to change the viewpoint of developmental psychology that accepts youth culture positively; and, to present interdisciplinary studies related to mass culture. Mass culture has already penetrated deeply into real life but there are few analyses and interpretations of mass culture in terms of psychology. This study is meaningful from the aspect that discussion of mass culture has been placed in a position that recognizes the entity of and interest in mass culture. Through this study, I hope that the scope of interest in psychology will expand and that approaches to mass culture will become more diversified.
