주세환,허윤석 한국무역학회 2023 Journal of Korea trade Vol.27 No.6
Purpose – This study is intended to identify the relationship between corporate environmental factors and corporate performance to respond to trade market dynamics caused by climate change. This research is performed with the hypotheses that proposes the use of green supply chain management has an impact on environmental factors and corporate performance. Design/methodology – Based on previous research, the team investigates factors and variables, and conducted empirical study. This research paper performs factor analysis such as reliability and validity and structural equation model using SPSS 27 and AMOS 26 to test hypotheses and study model. Findings – This research paper sets environmental regulations, government support, and corporate cultures as corporates’ environmental factors and analyzes green supply chain management and corporate performance, which results in the similar findings to previous research, however new insight also comes out. Environmental regulations alone cannot have a direct impact on corporates’ environmental performance and government support has no impact on green supply chain management and corporate performance. Originality/value – Previous research focuses on the past’s environmental regulations and corporate cultures. On the other hand, this study analyzes nowadays environmental regulations and various government support. In addition, this research paper studies in consideration to overall circums- tances, whereas the previous research deals with ESG and green supply chain management separately. In other words, the recent green trends and factors are applied to this study analysis.

As economic activities expanded in ports, existing port cities registered rapid growth based on the intercomplementary synergies between ports and cities. The functional growth of the ports delivered their scale, cargo volumes, and technological progress, which prodded population influx into the port cities and the growth of transport-related businesses. Ports and port cities, which play a pivotal role in logistics in today's economy, are no longer able to seek production efficiency and face intensifying competition due to advanced foreign ports. Due to excessively concentrated production activities, a significant amount of greenhouse gases is emitted, and the environment and ecosystem continue to be destroyed due to pollution caused by ports. Due to the COVID-19 pandemic, the world is experiencing an unprecedented logistical crisis. Even in such a thwarting environment, the South Korean government is showing high interest in the growth of digital and eco-friendly to prepare for the post-corona era. This year, the port authorities in Busan, Incheon, Yeosu, Gwangyang, and Ulsan focus on ESG management and digitalization of the ports with a view to making them smart and eco-friendly. Unlike in the past when the local communities focused on economic activities committed to productivity for a symbiotic industrial structure, they now consider the environmental perspective that promotes sustainable industrial growth. Above all, it can be said that this is an important time when the harmony of the opposing factors of economic growth and environmental preservation is emphasized. This study examines the characteristics of a smart port in order to analyze the environmental problems of ports due to increase in world trade volume and vessel upsizing, and also tries to identify the eco-friendly elements of smart ports with the aim of promoting their sustainable growth. In particular, it examines whether the technological advancement brought about by the 4th Industrial Revolution has an impact on the environmental aspects that are concentrated in ports

Empirical analysis of how risk management by Korea’s exporting companies affects export performance
주세환,박명섭 한국무역학회 2017 Journal of Korea trade Vol.21 No.4
Purpose – The purposes of this paper are as follows. First, the paper investigates the causes of risk and methods for managing it based on previous studies of trade risk and trade risk management. Second, the paper analyses the types and forms of trade risk for exporting companies and investigate the relationship between actual trade risks and perceptions of trade risk. Third, the paper establishes a measurement device for trade risk management and export performance based on previous studies. Fourth, the paper derives the concepts based on the accumulated details to establish a research model and verifies a cause and effect relationship. Fifth, the paper analyses what kind of effect the perception of trade risk exerts on trade risk management. And sixth, the paper analyses the effect of the method of trade risk management on the export performance of exporting companies to shed light on the utility of trade risk management. Design/methodology/approach – The purpose in this research is to analyse the effects of trade risk management on the export performance of exporting companies. The authors have conducted a review of previous studies about trade risk, trade risk management, and the outcomes thereof. Based on that review, the authors have established a research model, derived hypotheses, and used statistical methods to verify those hypotheses. Findings – First, the authors analysed the methods of settling payments, transaction terms, the transportation environment, and experience in trade claims and found that they influenced the perceived level of trade risk. Second, exporting companies’ prior perception of trade risk determines which methods of trade riskmanagement are suitable. Third, the analysis of the methods of trade risk management and export performance found that financial performance was influenced more than non-financial performance by trade risk management. Originality/value – The authors determined whether trade risk management effectively counters the losses incurred as a result of the trade risks faced by exporting countries. The authors used an empirical statistical analysis to comprehensively analyse appropriate trade risk management and export performance. Prior to implementing the empirical analysis, the authors conducted research on trade risk and its management and established a research model and research hypotheses based on a theoretical background of trade risk methods appropriate to the circumstances faced by exporting companies.

Purpose - This study aims to examine the effect of entrepreneurship of start-ups on export performance when the business closure rate is higher than business start-up rate in Korea. Thus, this study analyzes various factors for start-ups established within the past seven years and uses export performance as an indicator. Prior to analysis of factors, the study defines the concepts of start-up factors based on various studies. Design/methodology - In order to analyze the export performance of startups, this study conducted an empirical analysis using statistical analysis. Theories were established based on previous studies, and hypotheses and research models were designed based on the established theories. Subsequently, in order to verify the research hypothesis and research model, factor analysis such as validity and reliability, and structural equation modeling were analyzed. Findings - As a result of analysis based on previous studies, we found that there is a difference between theoretical and practical aspects. Whereas previous studies showed that market orientation, technology orientation, and social capital have a direct impact on export performance, the present study analyzed that there is no such impact, and that technology capabilities were important as a result of the unique traits of start-ups. Originality/value - Existing studies have limitations in understanding the overall characteristics of a company by using market orientation, technology orientation, and social capital as individual independent variables. In addition, the existing researches have been analyzed in relation to corporate performance, whereas this study has been limited to export performance, so it can be regarded as different from other studies.

수산물의 한ㆍ중 FTA 원산지규정에 관한 연구: 6) –특혜관세적용의 쟁점사항을 중심으로–
주세환(Se-Hwan Joo),박진우(Jin-Woo Park) 한국해양비즈니스학회 2018 해양비즈니스 Vol.- No.39
Korea has pursued radical expansion of the Free Trade Agreement (FTA) since 2000. While the key to the Free Trade Agreement (FTA) is the level of market access and the country of origin, the question of whether a country possesses the capacity to properly utilize open markets is crucial. In other words, the development and possession of capabilities to execute and utilize FTA are important. Specifically, the capacity to comply with basic conditions for the application of preferential duties is required. The most fundamental condition is whether the object is permitted as an object of privilege, and if it is acknowledged as an originating good pursuant to what is defined in the agreement. For this, there must be a clear understanding of the agreement s details on what is permitted as an object of privilege and on the rules of origin so that preparations can be made to satisfy such criteria. In this way can the FTA, which has taken effect, be utilized and an economic effect be obtained through import and export. As such, this study performed detailed research on the general criteria for FTA rules for preferential origins and the criteria for determining origin according to each item, for the marine products subject to the Korea-China FTA. Furthermore, by way of an analysis of the restrictiveness of the rules of origin against the functions of trade barriers, the study deduced the degree of difficulty for satisfying the rules of origin.

애기장대 내 새로운 브라시노스테로이드 결합체의 분리 및 동정
Se-Hwan Joo(주세환),Yew Lee(이유),Seong-Ki Kim(김성기) 한국생명과학회 2011 생명과학회지 Vol.21 No.5
애기장대에서 추출한 효소원에 동위원소로 표지 된 ³²P-ATP와 ³H-castasterone를 기질로 하여 효소반응을 수행하여 얻어진 생성물을 분석한 결과 ³H와 ³²P의 활성이 동시에 검출되었다. 이 대사산물의 구조를 알아보고자 동위원소로 표지 되지 않은 CS, ATP를 이용하여 효소 반응하여 얻어진 대사산물의 GC-MS 분석결과 ion m/z 664의 값을 얻었는데, 이를 CS phosphate로 예상할 수 있었다. 상기의 대사산물 분획에 wheat germ acid phosphatase를 처리하여 phosphoester 결합을 깨뜨린 후 얻어진 생성물의 GC-MS 분석결과 CS의 spectrum을 얻을 수 있었는데 이를 통해 식물체 내 CS의 결합체로 인산화 된 형태가 존재할 가능성을 확인하였다. Metabolism of ³H-castasterone in the presence of ³²P-ATP was examined by an enzyme solution prepared from A. thaliana after a reversed phased HPLC, after which a polar metabolite labeled by both ³H and ³²P was obtained, suggesting that ³H-CS is phosphorylated by ³²P-ATP. To elucidate the structure of the phosphorylated CS, the same enzyme assay was carried out with non-isotopes labeled CS and ATP. In GC-MS analysis the metabolite gave a molecular ion at m/z 664 as a bismethanboronate, suggesting the metabolite is a CS phosphate. Treatment of wheat germ acid phosphatase that hydrolyzed phosphoester bond gave the same mass spectrum and GC retention time in GC-MS analyses, confirming that the metabolite is phosphorylated CS. This is the first example of phosphorylated conjugates of CS in plants.
