정종희,김성호 한국국제경영관리학회 2023 국제경영리뷰 Vol.27 No.4

The prolonged Russian-Ukrainian war has increased uncertainty in the global defense export environment, causing countries to increase spending on defense and demand more weapons systems. The defense industry is important for a country's growth as it helps test advanced technologies and gives the private sector an edge. The global defense industry is growing, and the defense export market is set to expand; thus, now is a good time to diversify the defense export market. This can be done by studying unplanned acquisition needs in overseas defense markets. The goal of this study is to analyze unstructured data to provide guidance for defense exports. This study utilizes the STP strategy as a theoretical background. The study aims to identify promising areas for export to specific target countries, focusing on Poland, the Czech Republic, and Romania. They want to strengthen their arsenals after the Russia-Ukraine conflict. As they supported Ukraine with arms, creating a defense power vacuum. They need to respond to the Russian security threat. So, these countries must strengthen their defense capabilities. We collected highly reliable unstructured data on each country's ten-year plan. This data focuses on acquiring weapons systems. Next, we used the TF-IDF technique to identify keywords from these countries' data, helping find important words regarding each country's big projects. Poland's plan for defense spending includes four important keywords on warships, showing it wants to improve its navy. The Czech Republic and Romania both had the highest number of keywords related to operating systems. Then, we sorted the keywords to show the plans shared by all three countries to acquire items. The aim was to promote economies of scale. The analysis showed that 8 of the 21 words refer to obtaining weapon systems for operations. This has revealed promising defense export items.

Early studies on live commerce primarily examined the impact of host characteristics on performance metrics. Consequently, these studies highlighted content differentiation factors, which may include employing more attractive or specialized hosts, albeit at higher costs. Moreover, researchers are focusing on consumer purchase intentions, yet there remains a notable lack of empirical analysis regarding actual sales performance. In Korea, approximately 80% of merchants engaging in live commerce are small businesses with limited resources and capabilities. Live commerce provides these SMEs an opportunity to explore diverse sales channels. This study aims to enhance the sustainability of live commerce in Korea by adopting the sellers' perspective. It identifies airtime and product assortment size as exogenous variables, easily measurable during streaming, which significantly influence the sales performance of live commerce. Additionally, hit views act as a mediator between sales performance and these independent variables. In this research focused exclusively on the women’s clothing sector, the findings indicate that airtime, product assortment, and hit views all significantly impact sales performance. Furthermore, we confirmed that the broadcast date has a moderating effect on sales performance, with distinctive impacts observed between weekdays and weekends.

Purpose This study examines multi-dimensional determinants affecting SCM 4.0, and identifies whether innovation orientation plays a role as a mediator between these exogenous variables and SCM 4.0. In addition, this study recognizes whether SCM 4.0 influences Korean export SME operational performance. Design/Methodology/Approach Drawing on the comprehensive perspective in TOE, DOI, and dynamic capability theory, this study hypothesizes that technological uncertainty and the relative advantage of ICT are positively related to innovation orientation as mediating variables between these exogenous variables and SCM 4.0, and leading to performance. Data were obtained through a survey sent to export manufacturing SMEs in Busan and Gyoungnam in Korea. Findings The results suggest that all exogenous variables are mostly significantly related to SCM 4.0. Also, innovation orientation as mediating variables is statistically significant between these exogenous variables and SCM 4.0. In addition, results show that SCM 4.0 influences SMEs operational performance positively. This is a reason for SMEs to implement SCM 4.0. Research Implications This study agrees with the findings of antecedents affirming that SCM 4.0 positively influences a firm’s operational performance primarily by possessing the innovation orientation of the organization. Finally, this study suggests that implementing SCM 4.0 in SMEs may increase a sustainable competitive advantage in a dynamic global SCM environment and corporate value in a long-term perspective.

E-Mentor categorizes its users according to the particularized objectives of learning, content difficulties, age of target learners, educational environments, and both contents and system satisfactions of users. Unfortunately, the rise of educational demand for MALL eventually brought about quantitative changes in the field of English education – the boom of variety of applications – which is causing inconvenience and confusion to learners who are highly motivated in applying MALL. E-Mentor gives EFL-Learners a standard by which to measure and choose the proper applications for English learning. Furthermore, the actual development and experimental studies of E-Mentor will possibly suggest a new paradigm of language learning, and it will enable researchers and teachers to be interested in trying the new methodological approach towards MALL. In this article, we briefly discuss the functional categories of E-Mentor and guide through the process of development of E-Mentor.
