The investigation delved into 457 pieces of scholarly work, encompassing articles, published theses, and dissertations from the National Research Foundation of Korea, spanning the period of the 1997 IMF financial crisis up to 2022. The materials were sourced using terms such as 'angel investment', 'angel investor', and 'angel investment attraction'. The initial phase involved filtering out redundant entries from the preliminary collection of 267 works, leaving aside pieces that didn't pertain directly to angel investment as indicated in their abstracts. The next stage of the analysis involved a more rigorous selection process. Out of 43 papers earmarked in the preceding cut, only 32 were chosen. The criteria for this focused on the exclusion of conference presentations, articles that were either not submitted or inconclusive, and those that duplicated content under different titles. The final selection of 32 papers underwent a thorough systematic literature review. These documents, all pertinent to angel investment in South Korea, were scrutinized under five distinct categories: 1) publication year, 2) themes of research, 3) strategies employed in the studies, 4) participants involved in the research, and 5) methods of research utilized. This meticulous process illuminated the existing landscape of angel investment studies within Korea. Moreover, this study pinpointed gaps in the current body of research, offering guidance on future scholarly directions and proposing social scientific theories to further enrich the field of angel investment studies and analysis also seeks to pinpoint which areas require additional exploration to energize the field of angel investment moving forward. Through a comprehensive review of literature, this research intends to validate the establishment of future research trajectories and pinpoint areas that are currently and relatively underexplored in Korea's angel investment research stream. This study revealed that current research on domestic angel investment is concentrated on several areas: 1) the traits of angel investors, 2) the motivations behind angel investing, 3) startup ventures, 4) relevant institutions and policies, and 5) the various forms of angel investments. It was determined that there is a need to broaden the scope of research to aid in enhancing and stimulating the scale of domestic angel investing. This includes research into performance analysis of angel investments and detailed case studies in the field. Furthermore, the study emphasizes the importance of diversifying research efforts. Instead of solely focusing on specific factors like investment types, startups, accelerators, venture capital, and regulatory frameworks, there is a call for research that explores a variety of associated variables. These include aspects related to crowdfunding and return on investment in the context of angel investing, ensuring a more holistic approach to research in this domain. Specifically, there's a clear need for more detailed studies focusing on the relationships with variables that serve as dependent variables influencing the outcomes of angel investments. Moreover, it's essential to invigorate both qualitative and quantitative research that delves into the theoretical framework from multiple perspectives. This involves analyzing the structure of variables that have an impact on angel investments and the decisions surrounding these investments, thereby enriching the theoretical foundation of this field. Finally, we presented the direction of development for future research by confirming that the effect on the completeness of the business plan is high or low depending on the satisfaction of the entrepreneurs in addition to the components.

스포츠 거버넌스 구축을 위한 시론적 연구

김민,서희진 한국체육정책학회 2021 한국체육정책학회지 Vol.19 No.1

The purpose of this study is to understand the concept of sport governance, research trends, components as a rational alternative to prevent various corruption, including privatization of today's sport organizations, lack of responsibility for organizational management, and unfairness in competition management. It is to present an alternative suitable for the domestic situation. Specifically, based on the concept of governance and the theoretical multidimensionality, the difference between governance in sport and sport governance was identified, and the research trends of domestic sport governance, components, and implementation cases of sport governance abroad were examined. Governance operated in the sport field is an essential institutional element that positively influences the sport organizations. The board of directors' role in the development and operation of organizational strategies in various non-profit sectors, including sport, was emphasized. In foreign countries, the board is being discussed as the core of the sport governance function, but it has been difficult to confirm the board of directors' role and function in the domestic sport orgranization. The proposed domestic sport governance establishment process is 'establishment of the board of directors education system,' 'development of evaluation scale based on disclosure data,' 'establishment of principles for the board's mission,' and ‘establishments the organization's self-assessment system’. Sport exist in all three aspects: public, private for-profit, and private non-profit, but building good sport governance requires continuous efforts at all organization levels.

Purpose: To evaluate the correlation between the conventional method and the clinical history method those determine intraocular lens (IOL) power for cataract surgery in eyes with prior laser in situ keratomileusis (LASIK) in the absence of pre-LASIK data. Methods: The medical records of 200 eyes in 100 patients who had been treated with LASIK for myopia and were followed up for more than 6 months were reviewed. The IOL powers by conventional method using post-LASIK keratometric value and by clinical history method were compared. Results: The mean values of IOL powers by conventional method, and by clinical history method were +20.00±1.48D (+13.74~+23.23D) and +20.79±1.28D (+17.27~+24.32D), respectively. The following equation describes the regular relationship between the two methods: IOLCHM (clinical history method)=0.708*IOLCM (conventional method) +6.624 (r=0.816, p<.01). Conclusions: This equation may offer more accurate IOL power for cataract surgery in eyes with prior LASIK surgery in the absence of pre-LASIK data.

김민,김태훈,유희태,Eue-Keun Choi,Hyung-Seob Park,Junbeom Park,Young Soo Lee,Ki-Woon Kang,Jaemin Shim,Jung-Hoon Sung,Il-Young Oh,정보영 대한심장학회 2021 Korean Circulation Journal Vol.51 No.3

Background and Objectives: Atrial high-rate episodes (AHREs) can be continuously detected by cardiovascular implantable electronic devices (CIEDs); however, the predictors of clinically relevant AHREs are unclear. Methods: This prospective multicenter study monitored 816 patients (median age 73 years, 40.4% male) without atrial fibrillation (AF) from September 2017 to July 2020. AHREs was defined as a programmed atrial detection rate >220 beats/min. The reference values of 6 minutes and 6 hours were set to analyze clinical implication of AHREs based on previously published data that the 6 minutes excluded most episodes of oversensing. Results: During a median follow-up of 18 months (interquartile interval 9–26 months), AHREs with the longest durations of >15 seconds, >6 minutes, and >6 hours and clinically documented AF by electrocardiography were noted in 246 (30.1%), 112 (13.7%), 49 (6.0%), and 24 (2.9%) patients, respectively. Among patients developing AHREs >6 minutes, 102 (91.1%) of 112 patients were identified at the 6-month visit. Patients with AHREs >6 minutes had higher proportions of sick sinus syndrome, subjects with atrial premature beat >1% on Holter monitoring, and larger left atrium (LA) size than patients with AHREs ≤6 minutes. Multivariable logistic regression analysis showed that LA diameter >41 mm (odds ratio [OR], 2.08; 95% confidence interval [95% CI], 1.25–3.45), and sick sinus syndrome (OR, 3.22; 95% CI, 1.91–5.43) were associated with AHREs >6 minutes. Conclusions: In patients with LA diameter >41 mm, and sick sinus syndrome before CIEDs implantation is associated with risk of developing AHREs >6 minutes.

김민,김우진,김창수,정보영 연세대학교의과대학 2019 Yonsei medical journal Vol.60 No.12

Purpose: Although the economic and mortality burden of atrial fibrillation (AF) is substantial, it remains unclear which treatmentstrategies for rate and rhythm control are most cost-effective. Consequently, economic factors can play an adjunctive role inguiding treatment selection. Materials and Methods: We built a Markov chain Monte Carlo model using the Korean Health Insurance Review & AssessmentService database. Drugs for rate control and rhythm control in AF were analyzed. Cost-effective therapies were selected using acost-effectiveness ratio, calculated by net cost and quality-adjusted life years (QALY). Results: In the National Health Insurance Service data, 268149 patients with prevalent AF (age ≥18 years) were identified betweenJanuary 1, 2013 and December 31, 2015. Among them, 212459 and 55690 patients were taking drugs for rate and rhythm control,respectively. Atenolol cost $714/QALY. Among the rate-control medications, the cost of propranolol was lowest at $487/QALY,while that of carvedilol was highest at $1363/QALY. Among the rhythm-control medications, the cost of pilsicainide was lowest at$638/QALY, while that of amiodarone was highest at $986/QALY. Flecainide and propafenone cost $834 and $830/QALY, respectively. The cost-effectiveness threshold of all drugs was lower than $30000/QALY. Compared with atenolol, the rate-control drugspropranolol, betaxolol, bevantolol, bisoprolol, diltiazem, and verapamil, as well as the rhythm-control drugs sotalol, pilsicainide,flecainide, propafenone, and dronedarone, showed better incremental cost-effectiveness ratios. Conclusion: Propranolol and pilsicainide appear to be cost-effective in patients with AF in Korea assuming that drug usage orcompliance is the same.
