basis for activating and systematically and continuously promoting remodeling projects METHODS : Using the International Roughness Index (IRI) and World Bank's HDM-4, a model for vehicle operating costs was estimated. The change in vehicle operating costs was calculated by inputting the pre- and post-remodeling IRI values into the estimated model. Additionally, the future IRI over the life cycle was derived using the results of a study on the changes in pavement conditions between conventional and remodeling methods. The vehicle operating costs for different maintenance alternatives were compared by inputting them into the estimated model. RESULTS : The improvement in road smoothness after the project resulted in an annual vehicle operating cost benefit of approximately 1.6 billion won, with an estimated benefit per kilometer of approximately 64 million won. Furthermore, a comparison of vehicle operating costs for maintenance alternatives over the life cycle revealed that the remodeling method led to savings of 2.1 billion won compared with conventional methods. CONCLUSIONS : The findings of this study will serve as fundamental data supporting the necessity and justification for remodeling projects, particularly in the current scenario, where the need for maintenance of existing roads exhibits a faster growth trend than the extension of new roads. Additionally, this study could be supplemented by further research focusing on the consideration of pavement conditions in unit cost estimation and additional benefit estimation studies tailored to remodeling projects.

진자 시스템에서의 새로운 도약 현상의 실험적 관측과 이론적 해석

최동준,정완섭,김수현 한국소음진동공학회 1996 소음 진동 Vol.6 No.4

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.

최동준,김대명,유연우 한국부동산경영학회 2019 부동산경영 Vol.19 No.-

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.

Related Party Transaction and Revenue-Expense Matching

최동준,이한솔,윤인경,최원욱 한국세무학회 2022 세무와 회계저널 Vol.23 No.4

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.

영업비밀보호를 위한 전직의 자유 제한과 법익의 충돌 : 이분화된 미디어 담론의 역사적 변천과 법정책적 함의

최동준 법과사회이론학회 2023 법과 사회 Vol.- No.72

This study examines the media discourses on ‘litigation related to the mobility of technical employees to competitors’, the most typical form of trade secret misappropriation and investigates the process of how the media discourses of corporate rights of the intangible property(trade secrets) and employees’ freedom of mobility have been formed and changed. The media often represents events, phenomena, laws, and policies that deliver the interests of a specific group, and plays a significant role in driving public perception or legislation in a specific way. Drawing on this approach to the media, this paper examined how the constitutional values of “corporate rights of the intangible property(trade secrets)” and “employees’ freedom of career mobility” have been discussed and what evidence has been used to support the the discourse in relation to the operation of the trade secret protection system from the 1990s to 2020. To this end, a series of news media articles, namely 1401 news articles published in major Korean daily newspapers, the Chosun Ilbo, the JoongAng Ilbo, and the Dong-A Ilbo, and a major economic journal, the Maeil Business, were analyzed to distinguish the first period (1990s: the germination of corporate property rights discourse on trade secrets), the second period (2000s: the maturity of corporate property rights discourse on trade secrets), and the third period (2010s: the competition between the discourse on corporate property rights over trade secrets and the discourse on employees’ freedom of mobility) and further discover which discursive themes and rhetoric have been employed in each period. Ultimately, this study aims to examine the historical trajectories of the transformation of dichotomized media discourses that protect largely divided constitutional values, and to seek policy implications of law for ways to harmonize the interests of both companies and employees. In addition, the results of this study can be used to determine the increasing number of domestic and foreign lawsuits for trade secret misappropriation and to find the legal basis necessary to promote relevant legislation. 본 연구에서는 영업비밀 유출의 가장 전형적인 형태인 ‘경쟁사로의 기술직 근로자의 이직 관련 소송’에 관한 미디어 담론(media discourse)을 살펴보고 이를 바탕으로 기업 공동체의 재산권 보호와 노동자 개인의 이직의 자유라는 담론이 어떻게 형성・변화되어 왔는지 그 과정을 추적하고자 한다. 미디어는 한 사회의 사건, 현상, 법과 정책을 가치중립적 시각이 아닌 특정 집단의 이익을 대변하는 방식으로 다루며, 특정한 방식으로 대중적 인식(public perception)이나 입법을 견인하는 역할을 한다. 미디어가 가지는 이러한 영향력을 전제로 하여 본 논문은 1990년대부터 2020년까지 30년간 영업비밀 보호제도의 실질적 운용과 관련하여 ‘기업의 재산권 보호’와‘개인의 직업선택의 자유’라는 헌법적 가치가 어떻게 논의되어 왔으며, 그 담론적 근거가 무엇인지를 살펴보았다. 이를 위해 국내 주요 일간지인 조선일보, 중앙일보, 동아일보, 및 주요 경제지인 매일경제에 게시된 1401개의 뉴스기사를 분석하여, 제1시기 (1990년대: 영업비밀에 대한 기업의 재산권 강조 담론의 발아기), 제2시기 (2000년대: 영업비밀에 대한 기업의 재산권 강조 담론의 성숙기), 제3시기 (2010년대: 영업비밀에 대한 기업의 재산권 강조 담론과 근로자의 직업선택의 자유 강조 담론의 경합기)에 각각 어떠한 가치가 더욱 강조되었으며 그 담론적 근거 및 수사(rhetoric)가 무엇이었는지를 분석하였다. 궁극적으로 본 연구는 대별되는 헌법적 가치를 보호하는 이분화된 미디어 담론의 역사적 변천과정을 살펴보고, 이를 통해 양자 -기업과 근로자– 의 이익을 조화시킬 수 있는 방안에 대한 법정책적 함의를 모색하는 것을 그 의의로 갖는다. 또한 본 연구의 결과는 증가하는 국내외 영업비밀 침해소송을 판단하고 관련 입법을 추진하는 데 필요한 법적 근거를 찾는 데 활용될 수 있다.

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.
