This paper suggests a relative orbit control strategy for the CubeSat Astronomy by NASA and Yonsei using Virtual Telescope Alignment eXperiment (CANYVAL-X) mission whose main goal is to demonstrate an essential technique, which is an arrangement among two satellites and a specific celestial object, referred to as inertial alignment, for a next-generation virtual space telescope. The inertial alignment system is a relative orbit control system and has requirements for the relative state. Through the proposed orbit control strategy, consisting of separation, proximity keeping, and reconfiguration, the requirements will be satisfied. The separation direction of the two CubeSats with respect to the orbital plane is decided to provide advantageous initial condition to the orbit controller. Proximity keeping is accomplished by differential atmospheric drag control (DADC), which generates acceleration by changing the spacecraft’s effective cross section via attitude control rather than consuming propellant. Reconfiguration is performed to meet the requirements after proximity keeping. Numerical simulations show that the requirements can be satisfied by the relative orbit control strategy. Furthermore, through numerical simulations, it is demonstrated that the inertial alignment can be achieved. A beacon signal had been received for several months after the launch; however, we have lost the signal at present.

Korea's developmental skill formation system was shaped in the 1970s by the Korean developmental state that proactively sought rapid Heavy and Chemical Industrialisation as the nation's overarching goal. Vocational education at the upper secondary level and post-school in-company training in particular were strategically nurtured and closely managed by the state to supply the skilled workforce necessary, engendering a skill formation system subject to the state's policies. The state's tight control of the skill formation system was largely loosened in the 1980s, but since the 1990s it began to transform into a "post-developmental" skill formation system geared toward Korea's increasingly knowledge-based and globalising economy. Although it is still in the making, the post-developmental skill formation system is significantly different from the previous system in that the focus has shifted to vocational education at the secondary and the tertiary levels, whereas in-company vocational training is being gradually marginalised. Furthermore, the post-developmental skill formation system in Korea is both state-led and market-based, reflecting fundamental and dynamic changes in the nature of the Korean state since the 1990s.
