Abstract: The present invention relates to a fusion protein comprising a SARS-CoV-2-derived receptor-binding domain and a nucleocapsid protein, and the use thereof. The fusion protein comprising a coronavirus-derived receptor-binding domain and a nucleocapsid protein is highly applicable to a multivalent vaccine composition having greatly improved in-vivo half-life and remarkably superior efficacy compared to an immunogenic composition comprising only a receptor-binding domain. In particular, the fusion protein can greatly improve the titer of the coronavirus-specific antibody formation and T-cell immune response, and is thus useful for the prevention and treatment of coronaviruses comprising SARS-CoV-2.

Abstract: A trunk door is divided into two sub-doors to be folded in two steps. Even when it is difficult to open the trunk door due to a small distance between a vehicle and a wall, the trunk door can be easily and conveniently opened or closed. The sub-doors are formed to rotate in the same direction or rotate in the different directions. A length of a rotation radius along which the trunk door rotates is reduced. Thus, the trunk door can be conveniently opened or closed even in a small space. When there is a risk of coming into contact with the wall, since the outer sub-door is rotated in a backward direction to reduce a total rotation radius of the trunk door, the sub-door does not come into contact with the wall. Thus, the trunk door can be easily and conveniently opened or closed.
