Even though the life of a building fully remains, early complete withdrawal re-construction is carried out because of internal components fashioned. However, remodelling is activated by legal recently and the remodeling technology is increasing for sustainable development. This study grasp the internal components remodeling technology of Korea, America and Japan through analysis of patents so as to find out the proper direction of remodelling technology of internal components.

Auxetic material is a material which has negative Poisson's ratio(NPR). Auxetic material shows some distinctive property like high energy absorbing property and high shear modulus. Among these, synclastic curvature is very interesting characteristic. When synclastic-curvature-material bends, it changes its shape like dome, contrary to non-auxetic material which changes its shape like saddle(anticlastic). This distinctive property could make it easy to manufacture curved structure like nose cone or wing panel in aerospace engineering. In this study, we studied a quantitative analysis about synclastic curvature of re-entrant panel with finite element model. We suggested a concept 'Degree of Synclasticity(DOS)', which means a ratio of curvature of load-direction and load-orthogonal direction. We studied the variation of DOS with two factor, unit cell inner angle(${\theta}$) and load position angle(${\phi}$). DOS decreases as ${\theta}$ increases because the unit cell goes out of auxetic-shape. As ${\phi}$ varies, DOS changes in a large range. So proper optimization of ${\phi}$ would be needed for application.

Microstructure of a marine steel with a modified AISI-1004 composition was controlled by cold rolling and heat treatment, which corrosion behavior in an artificial sea water was electrochemically determined for the each deformation direction. The lowest corrosion rate of the surface normal to the rolling direction is related t the (111) fiber structure. Additional annealing at $550^{\circ}C$ for 24 hours improves the corrosion rate which is related to re-crystallization and reduction of (111) concentration.

In this study, we investigate the changes and realities of the content production process focusing on Image generation AI revolutions such as Stable Diffusion, Midjourney, and DELL-E, and examine the current status of related department operations at universities and Find out the status of the current curriculum. Through this, we suggest the need to produce AI-adaptive content talent through re-establishing the capabilities of content-related departments in art universities and quickly introducing curriculum. This is because it can be input into the efficient AI content development system currently being applied in industrial fields, and it is necessary to cultivate talent who can perform managerial and technical roles using various AI systems in the future. In conclusion, we will prepare cornerstone research to establish the university's status as a source of talent that can lead the content industry beyond the AI content production era, and focus on convergence capabilities and experience with the goal of producing convergence talent to cultivate AI adaptive content talent, suggests the direction of curriculum application for value creation.

Under a VMI (Vendor Managed Inventory) system, the vendor holds a certain level of control over not only inbound replenishment decisions on stocking but also outbound re-supply decisions. In this situation, vendor faces a better opportunity to synchronize the inventory and transportation decisions. However, shipment consolidation can reduce transportation expenses, but delivery time about the customer comes to be long and a customer service is fallen. Thus, a stock and transportation decision must consider this correlation. This study look into the relevant literature and suggest about further research direction.

The purpose of this paper was to design evaluation process on technological information analysis done by re-tired scientists and engineers. Existing studies on evaluation system and methodology were analyzed and their implications are as follows. To provide useful feedback to the retired scientists, indicators of evaluation should be simplified and method of evaluation confined to the quantitative one. And the results of evaluation need to be utilized in direction to encourage the old scientists and engineers.

In Korea, Green building certification system had been operated for more than 10 years and Expired certification buildings are ever-increasing. However, post management of building and qualification standard for re-certification(G-SEED) aren't exist, certificated green building don't have smoothly maintenance and management. Therefore, analysing the status and situation of similar system such as building maintenance and management, to suggest the direction of evaluation for green standard for energy and environmental design.
