Abstract: According to a preferred embodiment of the present disclosure, a project management device includes: a division unit configured to divide a project into n construction work packages (CWPs) based on a construction type constituting the project, a minimum unit area for managing the project, and design information; and a display unit configured to classify the n CWPs according to construction statuses and work front statuses and display the n CWPs in a grid form.

Abstract: Disclosed are a hot press-formed article and a method for manufacturing the same. The article is manufactured by hot press forming a galvanized steel sheet comprising a base steel plate and a zinc-based coat layer formed on a surface of the base steel plate, wherein the zinc-based coat layer contains at least one element selected from the group consisting of Sb, Sn, and Bi in a total amount of 0.05% to 2.0% by weight, and a balanced amount of Zn and inevitable impurities, at least 70% by weight of the at least one element selected from the group consisting of Sb, Sn, Bi being concentrated in a region 3 ?m or less distant from the surface of an alloyed zinc-based coat layer, formed by alloying the zinc-based coat layer, of the hot press-formed article.

Abstract: A method for manufacturing a screen including forming a phosphor layer on an inner surface of a panel where a black matrix layer is present; applying and drying a filming composition comprising an acryl emulsion having a molecular weight of 1.5-2.5 million and a decomposition starting temperature of 200.degree.-250.degree. C. as a main component on the phosphor layer to form a film; and forming a meal layer on the film.

Abstract: A filming composition comprises an acryl emulsion having a molecular weight of 1.5.about.2.5 million and a decomposition starting temperature of 200.degree..about.250.degree. C., as a main component. The composition has a tendency to decompose at low temperature and can be completely decomposed and removed during frit sealing, without the need for separate baking or complex equipment. A screen having good characteristics can be obtained through an advantageous method.
