이봉영 한국통신학회 1994 정보와 통신 Vol.11 No.2
지난 20여년간 광섬유전송방식의 고속화는 괄목할만한 성장을 이룩했다. 최근에는 어븀첨가광섬유증폭기의 개발로 인하여 10Gb/s의 초고속 광기간통신전송방식도 실용화를 앞두고 있다. 한편, 가입자에게도 광섬유가 포설되어 화상을 주체로 한 서비스가 제공되는 향후의 B-SIDN망에서는 전송로는 물론 노드까지도 초고속의 신호전송 처리가 필수이다. 그러나, 전기적인 처리를 기반으로 한 종래의 전송 처리기술로는 속도의 한계에 도달할 가능성이 많아서 이를 대체 할 수 있는 광소자개발 및 새로운 기술구축이 요구된다. 또한, 광솔리톤은 광섬유의 분산에 의해서 광펄스폭이 널어지지 않고 안정적으로 광섬유를 전파해가는 성질을 충분히 잘 활용한 기술로써 장거리 통신기술로 적합하게 개발되었다. 이와 같은 배경으로부터 본고에서는 차세대기간통신을 위한 초고속 초장거리 광전송기술 즉, 향후에 Tb/s 전송의 주역이 될 광주파수 다중기술 및 무중계 장거리 전송이 가능한 광솔리톤기술의 연구현황을 살펴보고 기술적인 문제점 해결을 위한 향후의 연구동향을 소개한다. High speed optical fiber transmission technology has been remarkably improved during the past 20 years. This paper presents recent research status and future technological issues for the future information society, that is, the Tb/s transmission by frequency division multiplexing and the ultra long-distance by optical soliton transmission. Erbium-doped fiber amplifier and recent optical technology have brought optical transmission system of up to 10 Gb/s to the point of commercialization. Taking into account the future super information highway, that is, B-ISDN network, ultra wide-band picture-based information can be provided for many subscribers via existing optical fiber cables. However, to achieve the high speed transmission, the technologies must be developed not only for transmission lines but also for transmission nodes. Since the conventional signal transmission/processing technique using electronics has the limit in its speed, novel photonic technology is being developed for this purpose. On the other hand, optical solitons propagate stably through optical fibers, without pulse broadening effect of the fiber dispersion. Since the pulse broadening effect becomes serious as the transmission speed increases, optical solitons is the important technologies to realize the high speed, long distance transmission.

봉영식 ( Youngshik Daniel Bong ) 한국군사학회 2022 군사논단 Vol.110 No.-
This article examines the alliance persistency between South Korea and the United States by comparing the two most recent summit meetings between the allies. The summit meetings in 2021 and 2022 provide breakthrough in the evolution of the alliance. The content of both summits is remarkably similar despite ideological differences between the Korean president. The summits also laid basic groundworks for the alliance to be steadily transformed into a global and comprehensive security partnership that is not confined to military issues but also promotes economic, technological and value-oriented cooperation.

소프트파워 관점에서 본 문재인 정부의 ‘한반도 운전자론’
봉영식 사단법인 한국국가전략연구원 2018 한국국가전략 Vol.3 No.3
This article examines the ‘Korean Peninsula Driver-Seat’ theory promulgated by the Moon Jae-In government of South Korea from the perspective of soft power of South Korea and thereby discuss how likely for the current diplomatic strategy of South Korea to succeed in both building a sustainable and irreversible peace regime and achieving a complete denuclearization on the Korean Peninsula. This study first surveys debates surrounding the theory of soft power in the field of international politics and proposes a 4-Ps test as a main framework of analysis to test the global leadership of South Korea. 본 연구는 문재인 정부가 지향하는 한반도 운전자론을 한국의 소프트파워 관점에서 분석하면서 한반도에서 지속가능하고 불가역적인 평화체제를 건설하면서 동시에 완전한 한반도 비핵화를 성취하려는 한국정부의 외교안보전략의 성공 가능성을 검토해본다. 본 논문은 먼저 소프트파워 이론을 둘러싼 국제정치학계의 쟁점을 간략하게 살펴보고, 구체적으로는 소프트파워에 대한 구체적인 분석틀 (4 Ps Test)을 제시하고, 이를 국제사회에서 한국의 리더쉽 분석에 적용해본다.

Choosing Partners: South Korean Public Opinion on the United States and China
봉영식,이지형 사단법인 한국평화연구학회 2016 평화학연구 Vol.17 No.2
Calibrating foreign policy in response to changing dynamics of US-China relations is indispensable for South Korea, to maintain security and establish the groundwork for peaceful unification.This article investigates South Korea’s search for security and unification partnerships in the context of the US-China rivalry by analyzing a series of recent South Korean public opinion surveys on foreign and domestic security protocols. Some key findings from the analysis are as follows first, the bilateral security partnership between South Korea and the United States has matured significantly. Unlike in the past when anti-American sentiment strained diplomatic ties, the South Korean public does not appear to ‘blame’ the U.S. as the primary obstacle undermining its effortsto democratize, develop its economy, and reconcile with North Korea. Second, contrary to predictions that South Korea will accommodate China’s hegemony in Northeast Asia, there is no convincing evidence to suggest that South Korea is drifting closer to China. South Koreans have largely portrayed conditional and often moderately negative attitude towards the rise of China. As such, South Korea needs to pre-emptively cope with the dual danger of entrapment and abandonment that has been created as a result of escalating tensions between the United States and China.

Unreal 4 기반 가상현실 군용 시뮬레이션 콘텐츠 제작사례
이상무,봉영균,신윤규,임창주 (사)한국컴퓨터게임학회 2017 한국컴퓨터게임학회논문지 Vol.30 No.4
Virtual reality is one of the most popular technologies in the fourth industrial revolution. We suggest that virtual training using virtual reality would be more effective than existing training. Development of virtual trolley simulation content was done through Unreal Engine. Through the production of virtual reality content, we had developed a more advanced simulation development environment.
