Securing a safe place to keep its collections in Busan, the interim capital during the Korean War, the National Museum of Korea could fulfill its mission to protect the national treasures. Right before Seoul was recaptured by the Communist forces, the museum managed to evacuate its collections to Busan in December of 1950. Until the armistice in 1953, a Korean government warehouse in Busan had to function as a temporary museum building. Protecting the national treasures in this small building, the National Museum of Korea had to maintain its role as a national museum and contribute in revitalizing cultural functions of Busan, the interim capital. The efforts led to hope for reconstructing the museum.

This research does by purpose that present safe navigation plan for ships during doing dredging construction with dredger crossing waterway of Gadeok Dredging operations need to build sunken tunnel that cross the bottom of the sea under waterway of Gadeok for access road construction between Busan- Geoje. Accordingly, dredger must cross and dredge waterway of Gadeok fatally. There is possibility of marine accident of collision for latent danger situation of ships to navigate waterway of Gadeok relatively. Therefore, safe navigation plan of ship is groped in reply and its countermeasure is presented. Firstly, navigating traffic in daytime was forecasted less than 20% of its maximum capacity through estimating the traffic volume and traffic congestion The proposal was presented to execute dredging operations in three-step and to establish temporary waterway after reviewing waterway design principles. The role of VTS center was emphasized in the new Busan Port, lastly.

There are 24 airways in Incehon IFR, including 11 domestic routes and 13 international routes. The airways designated by ministry of Transportation and Construction are the routes for aircraft to fly being serviced by air traffic control system for flight safety. This study reviewed safety situation of existing permanent airways within Incheon IFR and temporary airways connecting North and South Korea. The study tried to identify the problems related to airway operation and to suggest solutions to the questionable area. The main findings are as follows: It is necessary to improve the existing normal airway systems and enlargement of the route. The airway A593 has to be upgraded to normal route. The temporary airways established to connect Seoul and Pyongyang also needs to be upgraded by air traffic control transfer agreement between two Koreas.

Recently, as per a representative education method to develop core capabilities (such as critical thinking, communication, collaboration, and creativity) problem based learning (PBL) has been widely adopted in universities. Two important features of PBL are 'collaboration between team members' and 'participation based self-directed learning'. These two features should be satisfied in online education, although it is difficult due to the limitation on space and time in the COVID-19 pandemic. This paper presents a new design of PBL class in Metaverse, based on improving the online PBL class operated in the previous semesters in the H university. In the proposed PBL class, students are able to display materials (e.g., image, pdf, video files) in 3D virtual space, that are related to problem solving. The 3D virtual space is called gallery in this paper. The concept of gallery allows for active participation of students. In addition, the gallery can be used as a tool for collaborative meeting or for final presentation. If possible, the new design of PBL class will be applied and its effectiveness will be analyzed.

Exogenous lipoid pneumonia (ELP) is an uncommon condition resulting from aspiration or inhalation of vegetable, animal or mineral oil. It results in foreign body type inflammatory reaction of the lung and can show various clinical presentations from asymptomatic incidental finding to severe pneumonia leading to acute respiratory failure. Although many cases have been reported, severe ELP requiring steroid or whole lung lavage for treatment is rare. We report a case of 51-year old man with esophageal cancer who developed severe ELP following ingestion of large dose shark oil (Squalene) and successfully treated with prednisolone.

GSM(Global System for Mobile communications) that is the most popular standard for mobile phones, has more than 70% users in the world and the number of users increase continuously. However GSM system has the problem that cannot normally authenticate a user by the exposure of IMSI that is able to uniquely authenticate MS? during the user authentication procedure. In this paper? we provide security enhancement and user privacy by adopting a temporary id and an encryption scheme. Moreover we provide fast user authentication via architecture modification of the conventional GSM user authentication protocol.
