The seating postures of passengers in the automated driving vehicle are possible in atypical forms such as rear-facing and lying down. It is necessary to improve devices such as airbags and seat belts to protect occupants from injury in accidents of the automated driving vehicle, and collision safety evaluation tests must be newly developed. The purpose of this study is to define representative types of head-on collision accidents to develop collision standards for autonomous vehicles that take into account changes in driving behavior and occupants' postures. 150 frontal collision cases remained by filtering (accident videos, images, AIS 2+, passenger car, etc…) and random sampling from approximately 320,000 accidents claimed by a major insurance company over the past 5 years. The most frequent accident type is a head-on collision between a vehicle going straight and a vehicle turning left from the opposite side, accounting for 54.7% of all accidents, and most of these accidents occur in permissive left turns. The next most common frontal collision is the center-lane violation by drowsy driving and careless driving, accounting for 21.3% of the total. For the two types above, data such as vehicle speed, contact point/area, and PDOF at the moment of impact are obtained through accident reconstruction using PC-Crash. As a result, two types of autonomous vehicle crash safety test scenarios are proposed: (1) a frontal oblique collision test based on the accident types between a straight vehicle and a left-turning vehicle, and (2) a small overlap collision test based on the head-on accidents of center-lane violation.

박요한,박형근,홍석창,이명모,Hyojun Jung,조원제,Eun-Jin Kim,Ho-Young Son,이미옥 대한약학회 2012 Archives of Pharmacal Research Vol.35 No.8

Thirty two thiourea derivatives were prepared and their agonistic activities on the retinoic acid receptor-related orphan receptor α (RORα) were evaluated. The replacement of the 3-allyl-2-imino-thiazolidin-4-one moiety of the lead compound CGP52608 (1) with various functional group substituted aromatic rings, improved the agonistic activity of RORα. Among the prepared derivatives, 1-methyl-3-(4-phenoxy-benzyl)-thiourea (32) showed 2.6-fold higher agonistic activity than CGP52608 in the RORα-activation assay.

Security Improvement of ID-based Multiple Key Management Scheme for t Scalable Ad Hoc Networks

박요한,박영호,문상재,Park, Yo-Han,Park, Young-Ho,Moon, Sang-Jae Korea Society of Industrial Information Systems 2011 한국산업정보학회논문지 Vol.16 No.2

Security supports are a significant factor in mobile ad hoc networks. Especially in dynamic topologies, considering cluster, key management is essential to provide a secure system. Recently, Li-Liu proposed iD-based multiple key management scheme for cluster-based ad hoc networks. However, we found the security weakness of their scheme. In this paper, we analyze the security of Li-Liu's scheme and show that master secret key and fragment of the master secret key can be revealed to compromised CHs and nodes. Furthermore, we propose a solution to improve the scheme against disclosure of the share key and the master secret key even though system parameters are opened to compromised nodes and modify the Li-Liu's scheme fitted for a scalable networks. The improved IMKM scheme could be usefully applied in dynamic cluster-based MANETs such as the military battlefields, mobile marketplace and VANETs.

Implementation of Secure Vehicular Communication System in u-TSN

박요한,박영호,문상재,Park, Yo-Han,Park, Young-Ho,Moon, Sang-Jae The Institute of Electronics and Information Engin 2011 電子工學會論文誌-TC (Telecommunications) Vol.41 No.5

u-TSN은 운전자들과 보행자들을 위하여 도로 안전과 교통 관리를 용이하게 하는 차세대 기술이다. u-TSN을 실제 환경에 사용하기 위해서는 개인의 정보와 통신상의 데이터를 위부 공격자로부터 안전하게 보호해야 한다. 상대적으로 무능한 공격자라도 u-TSN이 가질 수 있는 장점들을 방해하고 사용 불가능하게 만들 수 있다. 따라서 안전한 u-TSN을 구현하기 위해서는 악의적인 공격자의 공격들은 방어하는 것이 중요한 과제 중의 하나이다. 본 논문에서는 u-TSN 환경에서의 보안 시나리오를 소개하고 이를 IXP425 보드에 구현한다. 보안 모듈로 구현된 보안 시스템은 u-TSN 환경에서 안전하고 효율적인 통신을 제공한다. u-TSN is a promising technology facilitating road safety and traffic management for drivers and passengers. To deploy this technology in a real environment, personal information and communicated data should be protected against malicious adversaries. Even though such adversaries would appear relatively infrequently, in such cases, the benefits of u-TSN could be disrupted and disabled. Therefore, one of the ultimate goals in the design of secure u-TSN is to protect against attacks of malicious adversaries. In this paper, we present secure communication scenario for u-TSN and implement security protocols and algorithms that are the components of the scenario on an IXP425 board. The security systems, implemented as a security module, supports secure and efficient communication for the u-TSN.

아시아 개발도상국 대상 사이버범죄대응 교육 모형 개발과 적용

박요한,신지호 경찰대학 치안정책연구소 2020 치안정책연구 Vol.34 No.4

Cybercrime is rapidly changing according to the development of IT technologies such as mobile, blockchain, and data, so systematic countermeasures are needed. In particular, in order to strengthen the responsiveness of developing countries in Asia, which are vulnerable to crime, international social organizations are making global efforts to jointly respond to cybercrime, such as developing and transmitting systematic training programs. However, there is a limitation in that discussions on the necessity of education and training have been the main focus of the discussions, and detailed studies on the development of training methods and contents are difficult to find. Therefore, in this paper, a curriculum design model and methodology for countering cybercrime for law enforcement agencies in developing countries in Asia were proposed. It is possible to design a customized curriculum specialized for the subject of education through the design of a two-dimensional module matrix, which was not covered in previous studies, and weight calculation for each module. In order to verify the effectiveness and effectiveness, the proposed methodology was actually applied to the invitational training for strengthening digital forensic competence for Sri Lankan police officers, and as a result, high scores were obtained in the process evaluation. The proposed methodology contributes greatly because it can be used as a guideline when transferring the security system of the Korean national police. 사이버범죄는 모바일, 블록체인, 데이터 등 IT 기술의 발전에 따라 발생 양상이 빠르게 변화하고 있으므로 이를 위한 체계적인 대응방안이 필요하다. 특히 범죄 대응에 취약한 아시아 지역 개발도상국의 대응력 강화를 위해 국제사회기구는 체계적인 훈련 프로그램을 개발하여 전수하는 등 사이버범죄 공동 대응을 위한 범지구적 노력을 기울이고 있다. 그러나 그간의 논의는 교육훈련의 필요성에 대한 논의가 주를 이루었고, 훈련 방법과 콘텐츠 개발 등 교육 모형에 대한 상세 연구는 찾아보기 힘들다는 한계가 존재한다. 이에 본 논문에서는 아시아 개발도상국 법집행기관 대상 사이버범죄 대응을 위한 커리큘럼 설계모형과 방법론을 제안했다. 기존 선행 연구에서 다루지 않은 2차원 모듈 매트릭스 설계, 모듈별 가중치 산정을 통해 교육대상에 특화된 맞춤형 커리큘럼 설계를 제안하고 효과성을 검증하기 위해 스리랑카 디지털포렌식 역량 강화 연수 과정에 제안방법론을 실제로 적용해 보았다. 그 결과 과정 평가에서 높은 점수를 얻었다. 본 연구에서 제안한 방법론은 그간 국제사회에서 제시되지 않은 아시아 개발도상국 대상 사이버범죄대응 교육 시 활용 가능한 실효성 있는 교육모형을 제시하였다는데 의의가 있다.

Economic Interdependence, Polity Type, Conflict and Peace: When Does Interdependence Cause Peace and Cause War?

박요한 서울대학교 국제학연구소 2018 Journal of International and Area Studies Vol.25 No.1

Competing IR paradigms have long debated the relationship between trade and conflict. Some view trade as causing interstate conflict whereas others see it as pacifying interstate relations. To address this ongoing scholarly debate, this study proposes an interactive relationship of interdependence and polity type in affecting peace. I argue that trade interdependence differently affects interstate relations between democracies and autocracies: interdependence causes conflict for autocracies while causing peace for democracies. This interactive hypothesis is tested against the directed-dyad sample of 1950-2001 for which all the relevant data are jointly available. My probit analysis reveals that interdependence increases the probability of conflict initiation for autocratic challengers but decreases it for democratic challengers.

How Does Economic Development Lead to Peace?: Economic Development and Interstate Armed Conflict, 1950-2011

박요한,우정무 서울대학교 국제학연구소 2022 Journal of International and Area Studies Vol.29 No.2

Zones of peace in the world are found to be where economically advanced democracies are grouped together. Indeed, these countries not only enjoy political freedom and economic affluence but also peaceful foreign relations. While numerous studies have advanced theoretical arguments and documented empirical evidence on the democratic peace, relatively scant attention has been paid to how economic development brings about international peace. Representative studies on the economic peace have shown serious theoretical and empirical loopholes in establishing the relationship between development and peace. This present study identifies four related but distinct explanations drawing upon the rich theoretical tradition of the economic peace encompassing both classical literature and modern scholarship. It also offers a more comprehensive test against the all dyad year data of 1950-2011. The findings show that the rate of armed conflict is lower for developed dyads than undeveloped dyads and mixed dyads. Developed countries rarely fight each other.
