Objectives : This study investigated the relationship between presymtoms and stroke subtype in early state of stroke patients. Methods : From Oct. 2005 to May 2007, 623 early state stroke patients were included. Patients were hospitalized within 30 days after the onset of stroke at DongGuk University International Hospital, Kyungwon University In-cheon Oriental Medical Hospital, or Kyung Hee University Oriental Hospital. We investigated general characteristics, stroke subtype, and presymtoms (facial spasm, neck stiffness). Results : Hemorrhagic stroke had more facial spasm than ischemic stroke(odds ratio 2.80). Small vessel occlusion had more neck stiffness than others(odds ratio 1.59). Conclusions : Facial spasm and neck stiffness would be valuable as stroke presymtoms.

This paper introduces a newly designed pendulum system that enables the more accurate boservation of dynamic behaviour arising from both horizontal and vertical(i.e. two dimension) excitation. First, experiments were carried out to examine the frequency responses of the devised pendulum system. Interestingly, experimental results for the three excitation angles of 22, 32 and 48 degree show 'new' jump phenomena. For the further understanding of these phenomena, experimental investigationhas been made to identify the equation of motion of the pendulum system from experimental data. This attempt has revealed that the viscous, coulomb and aerodynamic damping factors are involved in the equation of motion. By applying the Ritz averaging method to the equation, it becomes apparent that the jumping phenomena of the pendulum system in this work is more theoretically understood.

서민금융의 규제방향

최동준 한국금융법학회 2008 金融法硏究 Vol.5 No.2

A decade ago, Korea experienced the financial crisis, which helped regain the financial strength as never before. In the course of the recovery the citizens, the common people, who are low-income, low-credit consumers, suffered to the high interested loan and fell in the under-privileged and excluded segments in the financial markets. The People’s Finance means to provide services and credit by small amounts to the under-served and small businesses. Because of the growing dichotomy between the haves and the have-nots, it is essential to support the People’s Finance for the stable economic growth. The People’s Finance Institutions, which treat the People’s Finance, include Mutual Savings Banks, Credit Unions and Credit Cooperatives, Community Credit Cooperatives, Credit- Specialized Finance Companies, money lenders. It is suggested three ideas to support the People’s Finance. First, the financial literacy and education to the people is necessary. It helps to avoid badcredit status to normal financial status by understanding the importance of the credit in economic livings and establishing a healthy consumption behavior. Before reaching to the normal status they be also helped credit delinquents find jobs in order to make a living by themselves and repay their debt by the no-profit oriented entities. Second, building the People’s Finance Specialized Institution is demanded in order to finance the People’s Finance in smooth. Third, the diversified supervisory power of the People’s Finance Institutions should be united.

이 연구는 전자계약에 대한 이론적 배경을 정리하고, 국토교통부 부동산거래 전자계 약시스템에서 적용된 기술과 특징을 고찰하였다. 실제 전자계약서의 디지털 서명 구간 별로 내용을 변경하고 나타나는 무결성 여부를 검증했다. 연구 결과, 부동산 전자계약서는 디지털 서명 유효성 확인기능을 가진 PDF 문서뷰 어를 이용하여 무결성 검증이 가능하고, 인터넷 접속과 제 3자 증명 없이 무결성을 확인 할 수 있었다. 결과적으로, 계약서 소지자 본인 및 전자계약서를 제시받은 금융기관 및 공공기관에서 신뢰하고 이용할 수 있다는 것을 확인했다. 단, 디지털 서명검증 기능이 없는 PDF 문서뷰어를 이용하는 경우 제2종 오류 유형로 인한 위험이 발생할 수 있다. This study puts together the theoretical background of the electronic contract and reviews the technology and features applied in the electronic contract system for real estate transactions of the Ministry of Land, Infrastructure and Transport. In order to verify the integrity of the actual electronic contract, modification of the code of the electronic contract file was conducted for each digital signature section and the results were reviewed. This study shows that the integrity of the electronic contract of real estate transaction can be verified by using the PDF viewer which conforms to the international standard of digital signature validation, and the integrity of the electronic contract can be verified without Internet access and third party proof. As a result, it is confirmed that the holder of the electronic contract and the financial institution and public institution that have presented the electronic contract can trust and use electronic contract. However, if a user uses a PDF viewer without a digital signature verification function, the type 2 error risk may occur.

문책경고제도의 운영에 대한 고찰

최동준 한국금융법학회 2007 金融法硏究 Vol.4 No.1

The Disciplinary Warning is one of the supervisory sanctions against officers of the financial institution. It is stipulated in the sanction’s regulation by the Financial Supervisory Commission (FSC). Its effect is restricting the concerned officer from being appointed as an officer during certain period as set forth in each regulation on supervision of relevant financial institutions. In the Banking Act, the FSC may have the Financial Supervisory Service (FSS) Governor take an appropriate measure such as issuing a warning where any officer of a financial institution intentionally violates this Act or any rules, orders, or instructions under this Act, or performs an act which seriously damages the sound operation of the financial institution. And the specific matters on the qualifications for officers of financial institutions shall be determined by the FSC. Here arise problems whether the FSC’s sanction’s regulation can stipulate the Disciplinary Warning in spite the Banking Act describes only a Warning and it is right or authorized for the Disciplinary Warning stipulated in the regulation to restrict the concerned officer from being appointed as an officer during certain period. This paper discusses the legal character and legal basis of the Disciplinary Warning in detail, suggest the some items of the concerned Financial Laws to be amended.

This study examines the effect of firms’ related-party transactions on the contemporaneous relationship between revenues and expenses. Given that related-party transactions adversely affect earnings quality and stimulate earnings management by firms, this study predicts that related-party transactions negatively affect revenue-expense matching. Using data on Korean-listed firms for the period 2012-2019, a negative association was observed between related-party transactions and revenue-expense matching. Classifying related-party transactions into operating and non-operating related-party transactions, the results show that non-operating related-party transactions adversely affect revenue-expense matching. Furthermore, the negative association between related-party transactions and revenue-expense matching was more pronounced for firms with poor financial health. Specifically, for financially weak firms, non-operating related-party transactions adversely influenced revenue-expense matching. This study provides practical implications for investors and regulators by showing that related-party transactions critically influence the fundamental quality of earnings. Thus, it could impact investors’ valuation process. Moreover, the results suggest that regulators and standard setters should take related-party transactions into account to assess the regulations and accounting standards.

CNN Mobile Net 기반 악성코드 탐지 모델에서의 학습 데이터 크기와 검출 정확도의 상관관계 분석

최동준,이재우 한국융합보안학회 2020 융합보안 논문지 Vol.20 No.3

At the present stage of the fourth industrial revolution, machine learning and artificial intelligence technologies are rapidly developing, and there is a movement to apply machine learning technology in the security field. Malicious code, including new and transformed, generates an average of 390,000 a day worldwide. Statistics show that security companies ignore or miss 31 percent of alarms. As many malicious codes are generated, it is becoming difficult for humans to detect all malicious codes. As a result, research on the detection of malware and network intrusion events through machine learning is being actively conducted in academia and industry. In international conferences and journals, research on security data analysis using deep learning, a field of machine learning, is presented. have. However, these papers focus on detection accuracy and modify several parameters to improve detection accuracy but do not consider the ratio of dataset. Therefore, this paper aims to reduce the cost and resources of many machine learning research by finding the ratio of dataset that can derive the highest detection accuracy in CNN Mobile net-based malware detection model. 현재 4차 산업혁명을 맞이하여 머신러닝과 인공지능 기술이 급속도로 발전하고 있으며 보안 분야에서도 머신러닝 기술을 응용하려는 움직임이 있다. 많은 악성코드가 생성됨에 따라 사람의 힘으로는 모든 악성코드를 탐지하기 어려워지고 있기 때문이다. 이에 따라 학계와 산업계에서는 머신러닝을 통해 악성코드나 네트워크 침입 이벤트를 탐지하는 것에 관한 연구가 활발히 진행되고 있으며 국제 학회와 저널에서는 머신러닝의 한 분야인 딥러닝을 이용한 보안데이터 분석 연구가 논문 발표되고 있다. 그러나 해당 논문들은 검출 정확도에 초점이 맞추어져 있고 검출 정확도를 높이기 위해 여러 파라미터들을 수정하지만 Dataset의 개수를 고려하지 않고 있다. 따라서 본 논문에서는 CNN Mobile net 기반 악성코드 탐지 모델에서 가장 높은 검출 정확도를 도출할 수 있는 Dataset의 개수을 찾아내어 많은 머신러닝 연구 진행에 비용과 리소스를 줄이고자 한다.
