Background Interest in global health and international mission trips among medical student and resident trainees is growing rapidly. How these electives and international mission experiences affect future practice is still being elucidated. No study has identified if participation in international surgical missions during residency is a predictor of participation in international surgical missions in practice after training completion. Methods All trainees of our plastic surgery residency program from 1990 to 2011, during the implementation of optional annual international surgical missions, were surveyed to determine if the graduate had gone on a mission as a resident and as a plastic surgeon. Data were compared between graduates who participated in missions as residents and graduates who did not, from 1990 to 2011 and 1990 to 2007. Results Of Plastic Surgery graduates from 1990 to 2011 who participated in international missions as residents, 60% participated in missions when in practice, versus 5.9% of graduates participating in missions in practice but not residency (P<0.0001). When excluding last 5 years, graduates participating in international missions in practice after doing so as residents increases to 85.7%, versus 7.41% who participate in practice but not residency P<0.002. Conclusions Results reveal plastic surgeons who participate in international surgical missions as residents participate in international surgical missions in practice at higher rates than graduates who did not participate in missions during residency. International missions have significant intrinsic value both to trainee and international communities served, and this opportunity should be readily and easily accessible to all plastic surgery residents nationwide.

In Europe most Earth Observation (EO) data users rely on several EO missions, both to increase sustainability of their service and to widen the range of observation parameters. In addition to its own missions such as ERS 1 &2, ENVISAT and the Earth Explorers, ESA therefore offers access to the scientific and applications community to so-called 'Third Party Missions'. Third Party (TP) missions are complementing the observations of ESA missions, are used to prepare for future ESA missions including cross-calibration and create synergy to favor a wider use of EO data within ESA Member States.

I discuss the recent trend and future direction of spacecraft missions as well as remaining challenges in magnetospheric research. I hope this paper will be a handy guide to the current status and trend of magnetospheric missions.

Planarity geotechnical exploration missions were actively performed during the 1970s and there was a period of decline from the 1 990s to the 2000s because of budget. However, exploring space resources is essential to prepare for the depletion of Earth's resources in the future and explore resources abundant in space but scarce on Earth, such as rare earth and helium-3. Additionally, the development of space technology has become the driving force of future industry development. The competition among developed countries for exoplanet exploration has recently accelerated for the exploration and utilization of space resources. For these missions and resource exploration/mining, geotechnical exploration is required. There have been several missions to explore exoplanet ground, including the Moon, Mars, and asteroids. There are Apollo, LUNA, and Chang'E missions for exploration of the Moon. The Mars missions included Viking, Spirit/Opportunity, Phoenix, and Perseverance missions, and the asteroid missions included the Hayabusa missions. In this study, space planetary mineral resource exploration technologies are explained, and the future technological tasks of Korea are described.

Asteroids represent a significant resource for space exploration and scientific research. Various scientific missions have already performed and planned to investigate and understand the characteristics of asteroids. This talk introduces many space missions to asteroids. Representing missions to asteroids are the NASA's NEAR, Deep Space-1, Dawn, OSIRIS-Rex, SCOUT, DART, and ESA's Rosetta, and JAXA's Hayabusa 1 and 2, and DESTINY+ missions, and others. Although it is a very rare event, the possibility of Earth-crossing asteroids (ECAs) colliding with the Earth can never also be ignored. Numerous mitigation concepts also have been proposed to deflect ECAs in preparing for the disasters which might occur in future days. In the early studies for mitigation schemes, most of analyses were centered on to deflect ECAs with impacting the energy to the object to change its orbit. This talk also introduces many methods to deflect the orbit of ECAs, and shows spacecraft trajectories to asteroids.

In spite of a short history of only 30 years in space development, Korea has achieved outstanding space development capabilities, and became the $11^{th}$ member of the "Space Club" in 2013 by launching its own satellites with its own launch vehicle from a local space center. With the successful development and operation of more than 10 earth-orbiting satellites since 1999, Korea is now rapidly expanding its own aspirations to outer space exploration. Unlike earth-orbiting missions, planetary missions are more demanding of well-rounded technological capabilities, specifically trajectory design, analysis, and navigation. Because of the importance of relevant technologies, the Korean astronautical society devoted significant efforts to secure these basic technologies from the early 2000s. This paper revisits the numerous efforts conducted to date, specifically regarding flight dynamics and navigation technology, to prepare for future upcoming planetary missions in Korea. However, sustained efforts are still required to realize such challenging planetary missions, and efforts to date will significantly advance the relevant Korean technological capabilities.

The unknown excess emission in the near-infrared is thought to be related to the evolution of galaxies in the early epoch of Universe. Due to its extremely faint brightness, it can be observed only in space. Many infrared space missions have been tried to trace the origin of the Cosmic Infrared Background through the measurement of its absolute brightness and its spatial fluctuation. In addition, the infrared observations can address questions ranging from the origin of first galaxies in the Universe to the formation of stars. I will overview the Korean infrared space missions and introduce the status of the recent international collaboration mission, SPHEREx.

UAVs have been deployed various missions such as deception, reconnaissance and attack since they have been applied in battlefield and achieved missions successfully instead of man. In the past, it is impossible for UAVs to conduct autonomous missions or cooperative mission between manned aircraft due to the limitation of the technology. However, theses missions are possible owing to the advance in communication and AI Technology. In this research, we identified the possible cooperative missions between manned and unmanned team based on air-to-air mission. We studied cooperative manned and unmanned tactics about fighter sweep mission which is the core and basic operation among various air-to-air missions. We also developed cooperative tactics of manned and unmanned team by classifying nonstealth and stealth confrontational tactics. Hereafter, we verified the validity of the suggested tactics using computer simulations.

The next generation small satellite-1 (NEXTSat-1) program has been kicked off in 2012, and it will be launched in 2016 for the science missions and the verification of space core technologies. The payloads for these science missions are the Instrument for the Study of Space Storms (ISSS) and NIR Imaging Spectrometer for Star formation history (NISS). The ISSS and the NISS have been developed by Korea Advanced Institute of Science and Technology (KAIST) and Korea Astronomy and Space science Institute (KASI) respectively. The ISSS detects plasma densities and particle fluxes of 10 MeV energy range near the Earth and the NISS uses spectrometer. In order to verify the spacecraft core technologies in the space, the total of 7 space core technologies (SCT) will be applied to the NEXTSat-1 for space verification and those are under development. Thus, the operation modes for the ISSS and the NISS for space science missions and 7 SCTs for technology missions are analyzed for the required operation time during the NEXTSat-1's mission life time of 2 years. In this paper, the operational concept of the NEXTSat-1's science missions as well as the verification of space core technologies are presented considering constraints of volume, mass, and power after launch.
