Strawberries are one of the main commodities in Korea and have been exported over 30 million dollar. And the safety has recently become an important issue in the agro-trade, pesticide residue is most important matter of safe agricultural products. As strawberries can be cultivated using elevated production system, so it is possible to use the drenching. When spraying the pesticides, the use of drenching can be lower amount of residual than using foliar treatment. In this study, time sequential residual amount of pesticides were compared between drenching and foliar application in strawberries. Pesticides were treated with the standard and double dosage and samples were collected at 0, 3, 6, 9, 13, 16 and 21 day and analyzed by LC and LC-MS/MS after liquid-liquid extraction and QuEChERS. Two pesticides were detected less than 1 mg/kg in all samples for drenching treatment. Carbendazim residues in drenching treatment were 5 to 25 times lower than foliar application. And azoxystrobin was not detected in strawberries of drenching treatment.

이효섭 ( Hyoseob Lee ) 글로벌금융학회 2023 글로벌금융리뷰 Vol.4 No.1

Generative AI is expected to accelerate the emergence of innovative services in the financial industry. It can be expected that conselling and customer support using chatbots will increase, and inexpensive and excellent robo-advisors and personal insurance service will become common. Owing to generative AI, credit rating models will be improved and financial companies will be able to easily respond to compliance risks. On the other hand, if generative AI becomes common, various risk factors such as leakage and hacking of personal information, damage to financial stability and consumer protection, and increased legal uncertainty may occur. Therefore, all members included in financial industry try to develop generative AI in a healthy way. To promote innovation, it is necessary to expand openness and integration of data and improve the regulatory framework into a negative system. In addition, we should monitor and manage risk factors that might occur with generative AI.

이효섭 ( Hyoseob Lee ) 글로벌금융학회 2022 글로벌금융리뷰 Vol.3 No.1

This paper aims to introduce the necessity of accelerating the 4th industrial revolution through fostering innovative venture companies and specific strategies of revitalizing the supply of venture capital. The Korean venture investment market has grown rapidly in terms of quantity, but there are many problems in terms of quality. First, we need to improve the CVC(Corporate Venture Capital) and soundness regulation of financial companies. Second, in order to help venture scale-ups, it is necessary to increase venture debt and review the introduction of BDC(Business Development Company) and SVB(Silicon Valley Bank) business model. Third, to facilitate venture exits, we need to introduce the dual class stock and vitalize both the junk bond market and secondary market.

이효섭 ( Hyoseob Lee ) 글로벌금융학회 2020 글로벌금융리뷰 Vol.1 No.1

This study aims to provide political suggestions for the sound development of the Korean financial investment industry in the post-COVID19 era. This paper predicts that the New Normal phenomena such as low interest rate, low growth, and low inflation will continue in the post-COVID era based on financial market data and overseas literature. If the New Normal phenomena continue, the herding behavior on financial investment products will increase, the volatility of the financial market will remain high, and the systemic risk might increase. The Korean Financial Supervisory authority should strive to minimize mis-selling and unfair trading and continuously monitor risks related to systemic risk.

한국 디지털 금융허브 전략의 필요성 및 과제

이효섭 ( Hyoseob Lee ) 글로벌금융학회 2023 글로벌금융리뷰 Vol.4 No.2

The Financial Industry will rapidly shift toward digital finance as a result of technological innovations in generative AI, Blockchain, and BigData. South Korea has been promoting the ‘Northeast Asia Financial Hub Strategy’ to improve the global competitiveness of the financial industry, but it is difficult to become an excellent financial hub compared to Singapore, Hong Kong, and Shanghai without easing corporate and income tax rates, improving employment and financial regulation, and universalizing the use of English. It is necessary to change the financial industry development strategy to a ‘Digital Financial Hub Strategy’ instead of ‘Northeast Asia Financial Hub Strategy’. This study suggests the following tasks for a digital financial hub strategy. First, South Korea government should actively support the overseas expansion of domestic fintech and financial companies and the export of ICT infrastructure related to digital finance. Second, we should nominate digital finance special zones with a lot of incentives such as tax benefits, startup and incubation support. Third, digital finance startup hubs should be established in major cities, and digital finance talent should be cultivated by designating digital finance high schools, universities, and graduate schools. Fourth, the existing financial regulatory system should be improved in a negative and principle-based manner in line with changes in the digital finance environment.

금융회사의 ESG 경영전략 방향

이효섭 ( Hyoseob Lee ) 글로벌금융학회 2021 글로벌금융리뷰 Vol.2 No.2

This paper aims to examine the necessity and limitations of ESG management and provide the role of financial companies. For the realization of stakeholder capitalism, there is no disagreement that companies should continuously promote ESG management. However, we have some limitations to promote ESG management such as the lack of incentives, the difficulty of objective evaluation, and the widening gap of ESG scores. Global financial companies are implementing various ESG management strategies to overcome these limitations and try to create social values. Korean financial companies also should promote ESG management by establishing ESG governance, expanding incentive-compatible ESG financial products, and improving evaluation and disclosure infrastructures to solve the ESG information asymmetry.

This paper aims to examine the impact of an increase in the size of crypto assets on financial stability and to provide political suggestions for the control of financial stability. Specifically, this paper introduces the recent trend on domestic and global crypto assets industry related to traditional financial services industry. Despite the growth of crypto assets, the negative impact of the increase in crypto assets in Korea is not significant. However, I find that the relationship between some crypto asset market and KOSPI market is increasing, and some banks are more dependent on the crypto asset services. The Korean Financial Supervisory authority should strive to monitor the possibility of crypto assets industry undermining financial stability.

본 연구는 평생교육사의 혁신행동을 증진시키기 위하여 선행요인으로 직무만족을 선정하고 직무만족과 혁신행동 간의 관계에서 지식공유의 매개효과를 검증하는 데 목적이 있다. 이를 위하여 직무만족, 혁신행동, 지식공유와 관련된 선행연구를 검토하고, 이를 토대로 변인 간의 모형을 설정하였다. 본 연구의 실제적 검증을 위하여 서울시 내 평생교육기관에 근무하는 평생교육사 209명을 대상으로 설문조사를 실시하였으며, 수집된 데이터는 SPSS(23.0)와 AMOS(18.0) 프로그램을 활용하여 분석하였다. 분석 결과는 다음과 같다. 첫째, 평생교육사가 자신의 직무에 만족할수록 혁신행동이 발현되는 것으로 나타났다. 둘째, 평생교육사의 직무만족과 혁신행동간 지식공유가 부분매개 하는 것으로 나타났다. 이러한 연구결과는 직무만족과 지식공유가 혁신행동에 긍정적인 영향을 미치고 있음을 나타내고 있으며, 직무만족이 혁신행동으로 연결되기 위해서는 무엇보다도 구성원 간 지식공유가 이루어져야 함을 의미한다. 상기 연구결과를 토대로 시사점과 향후 연구방향을 제시하였다. The purpose of this study is to select job satisfaction as a prior factor and to verify the mediating effect of knowledge sharing in the relationship between job satisfaction and innovation behavior in order to promote innovation behavior of lifelong educators. To this end, prior research related to job satisfaction, innovative behavior, and knowledge sharing was reviewed and a model was set up between the variables based on this research. For practical verification of this research, a survey was conducted on 209 lifelong educators working for lifelong education institutions in Seoul, and the collected data was analyzed using the SPSS(23.0) and AMOS(18.0) programs. The results of the analysis are as follows. First, the more satisfied a lifelong educator is with his or her job, the more innovative action is expressed. Second, knowledge sharing between job satisfaction and innovative behavior of lifelong educators was found to be partial. These findings indicate that job satisfaction and knowledge sharing have a significant impact on innovation behavior, and that knowledge sharing among members must be achieved above all in order for job satisfaction to lead to innovation behavior. Based on the above findings, implications and future research trends were presented.
