Data is evaluated as a core resource for a company. But at the individual company level, there are criticisms that it is limited to rudimentary analysis based on limited data. Although there are many studies to solve this inefficiency, an implementation plan still need to be addressed. This study presents a theoretical and practical framework to fill this gap. First, from a theoretical point of view, the necessity of an integrated data transaction exchange is presented using the Knowledge Based view theory and the mission oriented policy theory. And from a practical point of view, we suggest not only exchange design and operation plans, but also a step-by-step strategy to increase data transactions. In addition, this paper provides the rationale for active use of user community functions and collaboration with scholars in field of business and economics in order to utilize user forums to solve factors that limit data transactions and apply the answers to real-world corporate management.

韓炳錫,李英河,羅榮彦,辛大煥 충남대학교 의과대학 지역사회의학연구소 1990 충남의대잡지 Vol.17 No.1

In order to evaluate the Toxoplasma antibody titers, authors were examined sera of 117 pregnant women by enzyme-linked immunosorbent assay(ELISA), methlyene blue dye test and indirect latex agglutination test. The results were obtained as follows: 1. The ELISA values to the Toxoplasma antibody showed less than 0.200 in 2 cases(1.7%), 0.20 0-0.299 in 13 cases(11.1%), 0,300-0.399 in 29 cases(24.8%), 0.400-0.499 in 143 cases(12.0%), 0.500-0.599 in 26 cases(22.2%), 0.600-0.699 in 19 cases(16.2%), 0.700-0.799 in 6 cases(5.1%), 0.800-0.899 in 7 cases(6.0%), more than 0.900 in 1 case(0.9%), respectively. Regard to positive ELISA values were more the 0.800, positive rates of ELISA were 6.9%. 2. The dye test antibody titers showed less than 1:4 in 70 cases (59.8%), 1:4 in 27 cases(23.1%), 1:16 in 13 cases(11.1%), 1:64 in 6 cases(5.1%), and 1:256 in 1case(0.9%), respectively. Regard to 1:64 or more tilers of diluted sere were positive, the positive rates of dye test were 6.0%. 3. The Toxoplasma antibody titers by indirect latex agglutination test were less than 1:2 in 9 cases(7.7%), 1:2 in 47 cases(40.2%), 1:4 in 27 cases(23.1%), 1:8 in 21 cases(17.9%), 1:16 in 7 cases(6.0%), 1:32 in 5 cases(4.3%), and 1:64 in 1 cases(0.9%), respectively. Regard to 1:32 or more titers of diluted sera positive, the positive rates of indirect latex agglutination test were 5.2% 4. There were correlation between dye test antibody titers and ELISA values(correlation coefficient, r=0.414). The present study revealed that Toxoplasma antibody titers of pregnant women by various immunoserologic methods showed 5.1∼6.9%.

파생계약부 소득연계대출의 역사

한병석,강형구 한국재무학회 2015 한국재무학회 학술대회 Vol.2015 No.05

본 연구는 파생계약부 소득연계대출의 역사적인 전개과정과 발전방향을 우리나라에서 최초로 검토하였다. 파생계약부 소득연계대출인 취업후상환대출(ICL)은 지난 2010년부 터 국내에서 운영되고 있다. 취업후상환대출은 소득발생이라는 전제조건이 충족되는 경 우에만 상환이 개시된다는 점에서 대출자(lender)의 관점에 보면 소득연계형 대출이라 고 할 수 있고, 차입자(borrower)의 입장에서는 취업이라는 옵션의 행사여부가 대출상 환과 연계되어 있다는 점에서 파생상품계약이라고 할 수 있다. 그러나 현재까지 파생계 약부 소득연계대출의 해외현황에 대한 연구만이 제한적으로 진행되어 왔다. 동 제도의 탄생배경 및 역사적 발전과정에 대한 연구는 전무한 실정이다. 한국의 특별한 상황을 고려한 연구도 없다. 이 연구는 이러한 기존 연구의 한계를 극복한다. 본 연구의 결과 는 다음과 같다. 학자금대출제도는 정부가 부담하던 고등교육비용을 점차 개인이 부담 하게 하는 방편으로 1950년대부터 도입되었다. 이후 1980년대에는 대출자의 경제적 부 담을 최소로 하기 위해 파생계약부 소득연계대출이 탄생하는 과정을 거치면서 전개된 것으로 나타났다. 또한 본 연구에서는 파생계약부 소득연계대출의 발전방향에 대해서도 예측했다. 파생계약부 소득연계대출은 채권형에서 주식형으로 그 성격이 변화될 가능성 이 큰 것으로 나타났다. 이러한 변화의 배경에는 각국 정부가 점점 대출자에 대한 부담 을 크게 만드는 방식으로 변경하고 있다는 점, 궁극적으로 관련비용을 개인이 전적으로 부담하는 방향으로 변경될 가능성이 매우 크다는 점 등이 있다. 본 연구는 파생계약부 소득연계대출의 발전방향을 예측하였음은 물론 이를 통해 주식형 투자의 실현가능성과 추진체계를 구체적으로 제시하였다는데도 정책적 시사점을 가진다. We firstly document the history of derivatives contracting on the loan linked with human capital. Income Contingent Loan, a kind of derivatives contracting on loans has been introduced in the country since 2010. Income Contingent Loan is an income-contingent derivative loan from lender's viewpoint in that payments begin only if a precondition is met. It is a derivatives contracting from borrower's viewpoint as well; whether to exercise the option of getting-a-job depends on repayment strategy. However, existing research only analyzes the current status of foreign cases without considering their history and Korean specific factors on the derivatives contracting for loans . There is no research on its background and historical development. We fill the gap of this literature using interesting international cases. We find that student loan system has been introduced in order to encourage individuals to pay higher fraction of education cost which the government has paid since the 1950s. In the 1980s, student loan system has particularly evolved and become to create derivatives contracting on the loan in order to minimize lender's economic burden and risk exposure. Furthermore, this study examine the future prospect of derivatives contracting on loan. The derivatives contracting on loan will evolve from debt-like toward equity-like investment. This will reduce the burden and exposure of governments while increasing the investment on human capital. This study has many policy implications discussing the development of student loan system, its vision and implementation.

Strategic Branding of Financial Services:An Analysis of Income Contingent(DeunDeun) Student Loan Contracts

한병석,전희경,전상경,강형구 한국경영교육학회 2016 경영교육연구 Vol.31 No.5

[Purpose]Despite the fact that many students rely on student loans to fund university tuition, there is little brand research that focuses on financial products related to education. This is especially the case for income-contingent student loan contracts. [Methodology]In this case study, we review relevant literature on brand strategy and utilize Keller’s theory on brand equity to formulate a strategy for successful brand management of income-contingent loan contracts. [Findings]Income-contingent student loan contracts differ from other student loan products in that students can repay their debts after they start to generate income. But despite the merits of such loans, such as DeunDeun Student Loan, they remain largely unknown to most students. [Implications]Successful brand management of income-contingent loans should generate sufficient demand from end users and, in turn, enhance the welfare of students. In addition, broader benefits of this analysis include capability enhancement of policymakers in designing and promoting financial products, especially those related to education.

디지털 전환시대의 지역금융기관 경영전략 : BNK금융지주 사례를 중심으로

한병석,최영두,오대원 한국무역통상학회 2021 무역통상학회지 Vol.21 No.6

Local banks play a very important policy role in that they are the starting point for regional economic development. Therefore, the academic review on the survival and growth of local banks is urgent and important. To ensure local banks‘ role in the digital financial era, this paper presents a practical strategy for the survival of local banks using BNK Financial Group as a case. Specifically, we suggest a strategy of reorganizing the existing Busan Bank and Kyongnam Bank into a two-bank system of BNK Bank and BNK Digital Bank to compete with big commercial banks and Internet-only banks. This study also proposes a two-track marketing model for BNK Bank and BNK Digital Bank respectively: (1) securing existing customers through positioning as a new top 5 commercial bank; (2) penetrating new customers with the co-operation of tech companies such as NC Soft and NAVER.

초임계 이산화탄소를 이용한 홍화로부터 황색소 추출

Supercritical fluid(SCF) carbon dioxide was used to extract safflower yellow pigments from Carthamus tinctorius L. In this work, supercritical fluid extractions were performed at various conditions; pressure (2000, 3000, 4000, 5000 psig), temperature $(40,\;50,\;60,\;70,\;80^{\circ}C)$ and co-solvent $(0,\;3,\;6,\;10,\;14\;wt%\;H_2O)$. Total concentrations of safflower yellow pigments extracted were determined by spectrophotometric method. A maximum yield of yellow pigments was obtained at 4000psig, $60^{\circ}C$ and 10% co-solvent. The extraction yield of pigments was also closely related to moisture content of the raw material. Extraction yield of safflower yellow pigments by SCF extraction at optimized conditions was 6% higher than that by solvent extraction. Supercritical carbon dioxide was proved to be suitable for the extraction of safflower yellow pigments from Carthamus tinctorius L. 홍화로부터 초임계 이산화탄소를 이용하여 황색소(safflower yellow)를 추출할 때의 최적 조건을 조사하였다. 여러 온도$(40,\;50,\;60,\;70,\;80^{\circ}C)$와 압력(2000, 3000, 4000, 5000 psig) 조건에서 추출을 하였으며 수율을 증가시키기 위해 물을 보조용매(0, 3, 6, 10, 14 wt%)로 하여 실험을 수행하였으며 색소분석은 spectrophotometer를 이용하였다. 황색소의 추출 수율은 $60^{\circ}C$, 4000 psig에서 가장 높게 나타났다. 보조용매로 물을 사용하였을 때는 10 wt%일 때 황색소의 추출이 가장 잘 되었고 그 이상에서는 오히려 추출량이 감소하는 경향을 보였다. 또한 시료의 수분함량은 초임계 유체 추출 시 수율과 밀접한 관련이 있는데 홍화의 황색소 추출 시에도 시료의 수분함량이 낮을수록 수율이 증가함을 알 수 있었다. 아울러 초임계 유체를 이용하여 최적 조건에서 추출한 경우 황색소의 수율은 용매로 추출한 경우에 비해 6% 정도 증가하였다. 상기의 결과로 초임계 이산화탄소 추출법은 홍화로부터 황색소의 추출에 적합하다는 것을 확인할 수 있었다.

A Case Study of Option Shock in the Korean Stock Market

한병석,전상경,김은지,강형구 한국경영학회 2017 Korea Business Review Vol.21 No.4

This case study reviews the option shock, which occurred during the last ten minutes of trading on the expiry date of KOSPI200 options, Nov. 11th, 2010. KOSPI200 index plummeted by 2.79% on Nov. 11th 2010, which triggered the market collapse. By investigating participants’ behavior of the suspicious trading and their actual derivatives positions specifically, our study shows that the Nov. 11th Option Shock was the result of multiple violations of related regulations. Traders at an international securities company in Hong Kong made unfair profit with an intent to manipulate the market. Their colleagues in Korea also made money using the confidential trading information from the counterpart subsidiary in Hong Kong. The asset management firm placed option orders with trading amount well over the limit set by the regulatory code, and the local securities firm neglected to monitor the trading limit of the asset management. With these series of violations, billions of dollars of market capital evaporated, and investors lost millions of dollars. Similar incidences on the option expiration date have occurred all over the world. This study can provide the practical implications for policy makers and market participants. It also provides us with an excellent teaching opportunity in the areas of finance and business ethics.

디자인사고(design thinking)를 활용한 정책자금 지원대상 선정기준 개선방안

한병석 ( Byungsuk Han ),오대원 ( Daewon Oh ),강형구 ( Hyoung-goo Kang ) 한국재무관리학회 2023 財務管理硏究 Vol.40 No.6

한정된 재원으로 성공가능성이 높은 기업을 발굴하기 위한 절차와 평가기준을 어떻게 개선할 것인가에 대한 연구는 매우 중요한 정책적, 학술적 주제가 된다. 그러나 신생기업을 지원하는 과정에서 지원대상을 어떻게 선별할 것인가에 대한 주제는 국내에서는 거의 연구되지 않고 있다. 그간 이론적인 관점에서는 정책자금 지원의 필요성에, 실무적인 관점에서는 지원영역에 중점을 두고 있었던 연구 주제의 확장이 시급한 상황이다. 이런 필요성을 바탕으로 본고는 정부가 지원하고 있는 정책자금의 지원대상을 선발하는 절차와 기준에 대한 개선사항을 혁신의 새로운 기준으로 활용되고 있는 디자인사고 이론을 논거로 하여 국내 최초로 연구하였다는 점에서 의의가 있다. 또한 벤처투자가 가장 활성화 되어 있는 미국의 주요 엑셀러레이터의 선발기준에 대한 사례 분석을 통해 실제 투자 현장에서 직접적으로 활용될 수 있는 실무 가이드라인을 제시하였다는 점에서도 시사점이 있다. 이 과정에서 사용자 경험개선을 최우선시하는 디자인사고 이론이 프로토타입과 이의 제공주체인 창업자라는 형태로 해외 유명 엑셀러레이터들의 핵심 평가기준으로 활용되고 있다는 것을 논증하여 이론과 실제를 접목하는 연구방식을 활용한 점도 기존 연구와 차별성이 있다. 그리고 제도개선사항이 실질적으로 시행될 수 있도록 현행제도에 대한 보완사항도 제시하여 개선사항의 적용가능성에 대한 검토도 함께 하였다는 점에서 정책적 의의가 있다. Research on improving the criteria for selecting high-potential companies with limited resources is a crucial topic in both policy and academia. However, there has been little research in Korea on how to select candidates in the process of supporting startups. There is a pressing need to expand research topics that have been focused on the need for policy funding from a theoretical perspective and support areas from a practical perspective. Based on this need, this paper is significant in that it is the first study in Korea to suggest improvements to the process and criteria for selecting applicants for policy funds supported by the government based on design thinking theory, which is being used as a new standard for innovation. In addition, the case analysis of the selection criteria of major accelerators in the United States, where venture investment is most active, provides practical guidelines that can be directly used in the actual investment field. This study differs from previous studies in that it utilizes a research method that combines theory and practice by arguing that design thinking theory, which prioritizes user experience improvement, is being used as a core evaluation criterion for accelerators overseas in the form of prototypes and founders who provide them. In addition, it is of policy significance in that it also reviewed the applicability of the improvement by presenting supplementary matters to the current system so that the system improvement can be practically implemented.
