The presentation of this paper was triggered by the spread of MERS in Korea in the year 2015. The analysis of the present acts related with MERS is necessary in order to cope efficiently with any probable spread of such infectious diseases as MERS in future. The acts that should be analyzed in this paper include 'Medical Service Act' and 'Infectious Disease Control And Prevention Act' (hereafter, IDCAPA). At first the classification of the infectious diseases in IDCAPA should be referred to. The Act does not properly classify them because the scope of concept of each group of the infectious diseases overlaps each other. This overlap should be removed. The present system in IDCAPA is not proper for the efficient notification and reporting of the infectious disease patients. This is so in some viewpoints including the persons obligated to make the notification and reporting, the persons to whom they should notify and report such patients, and the process of notification and reporting. The efficient approach to the information related with the infectious disease is necessary for the rapid prevention of its spread. Cohort isolation and quarantine of the infectious patients and exposed contacts are the strongest and most efficient steps for the prevention of spread of the infectious diseases. One of the great problems related with such steps would be the conflict of powers or attributions, the likelihood of which is inevitable under the present system of IDCAPA. The IDCAPA distributed the power or attribution to take the steps to the three governments including the central government, the metropolitan government and the primary local government. The power should be concentrated in the central government, which could afford financially to compensate for the huge amount of damages caused likely by the steps. The power to take the steps would be actually just a useless thing for its holder without such financial capacity. The remedy for the victims by the fault of spreader should be approached to in the sense of national wealth. The general principle of tort law could not supply the victims with the sufficient remedy because the damages would be likely too huge for the wealth of such spreader to cope with. In future another parliamentary inspection could reveal another problems in the administration by the government of the MERS event in the year 2015. Any problem caused by defect in the legal system of the control and prevention of the infectious diseases should be taken into consideration when the legal system would be reformed in future.

This study reports comprehensive observations for the G5-level geomagnetic storm that occurred from May 10 to 12, 2024, the most intense event since the 2003 Halloween storm. The storm was triggered by a series of coronal mass ejections (CMEs) originating from the merging of two active regions 13664/13668, which formed a large and complex photospheric magnetic configuration and produced X-class flares in early May 2024. Among the events, the most significant CME, driven by an X2.2 flare on May 9, caught up with and merged with a preceding slower CME associated with an X-class flare on May 8. These combined CMEs reached 1 AU simultaneously, resulting in an extreme geomagnetic storm. Geostationary satellite observations revealed changes in Earth's magnetosphere due to solar wind impacts, increased fluxes of high-energy particles, and periodic magnetic field fluctuations accompanied by particle injections. Extreme geomagnetic storms resulting from the interaction of the solar wind with the Earth's magnetosphere caused significant energy influx into Earth's upper atmosphere over the polar regions, leading to thermospheric heating and changes in the global atmospheric composition and ionosphere. As part of this global disturbance, significant disruptions were also observed in the East Asian sector, including the Korean Peninsula. Ground-based observations show strong negative storm effects in the ionosphere, which are associated with thermospheric heating and resulting in decreases in the oxygen-to-nitrogen ratio (O/N₂) in high-latitude regions. Global responses of storm-time prompt penetration electric fields were also observed from magnetometers over the East-Asian longitudinal sector. We also briefly report storm-time responses of aurora and cosmic rays using all-sky cameras and neutron monitors operated by the Korea Astronomy and Space Science Institute (KASI). The extensive observations of the G5-level storm offer crucial insights into Sun-Earth interactions during extreme space weather events and may help establish better preparation for future space weather challenges.
