Options for the Security of South Korea

Abstract: In the strategic situation after the end of the Cold War in which South Korea does not have a long-term strategic importance to the United States and accordingly the United States will be unlikely send its troops automatically and immediately to South Korea in a crisis, there are options South Korea can choose from with regard to security. First is to increase South Korea’s own military capability. This can be achieved by increasing weapons productivity and investment in sophisticated military technology. The second option available to South Korea is to hold onto the presence of the US military. If current South Korean military capacity is not enough to counter that of North Korea, then South Korea should borrow US military capability to compensate. The third option is to weaken North Korea’s combat capability. This option could be achieved through bilateral talks possibly between China and North Korea, between the United States and North Korea, or between North Korea and Russia. If Russia and China are providing key combat elements to North Korea, South Korea could undermine North Korean military capacity by encouraging China and Russia not to do so. The last option is to hold direct North—South talks and reach a peace agreement. This would be the most desirable solution.

System Design and Implementation of Multi-legged Spider Robots for Landmine Detection in the Demilitarized Zone

Abstract: As the Korean demilitarized zone(DMZ) has unique geological features and terrains, conventional wheel-based unmanned ground vehicles(UGVs) are hard to perform the landmine removal tasks. Compared to other types of robot platforms, multi-legged robots, which climb the inclined way and overcome the complex obstacles with lower contact area on the ground, have several advantages to perform landmine detection tasks in DMZ effectively. Thus, to exploit such benefits, in this paper, we propose the design schemes and gait methods of multi-legged spider robots. Especially, this paper presents the design and motion control of multi-legged spider robots with four and six legs. In detail, we implemented the design and motion control of multi-legged spider robots suitable for landmine detection in the DMZ by applying the gait algorithms on Arduino and Dynamixel servomotors. Our proposed algorithm and system design demonstrate that the proposed system design architecture enables operational flexibilities while walking in harsh conditions.

Dermatofibrosarcoma Protuberans in Active Duty Military Personnel: A Case Report.

Abstract: Dermatofibrosarcoma protuberans (DFSP) is an uncommon, soft tissue sarcoma with a high rate of local recurrence, low rate of distant metastasis, and infiltrative growth. We report two cases of DFSP in young active duty military personnel. Both cases underwent primary excision at the Armed Forces Capital Hospital with positive surgical margins and underwent re-excision at Samsung Medical Center. Dermatofibrosarcoma protuberans is a rare finding, and wide local excision with or without skin flap remains the procedure of choice. Awareness of DFSP in young patients is important for proper diagnosis and treatment and to achieve local control. Complete excision of the tumor with a clear surgical margin and thorough surveillance after surgery are recommended for service members to maintain their active duty status and to prevent ineffective combat conditions.
