Today, in the midst of the culture and art of the digitized social developed fast-growing, and the same is true for all sectors of this design. This study is a space in the field of design, exhibition space and apply new techniques for rendering mode, also, in the past, the contents of simple and one-sided storytelling techniques with an emphasis on applying the method of display mode. Storytelling techniques applied in direct touch can experience the vigorousness of your exhibition space ' Hands-on ' approach to the exhibition, in this study, children experience exhibits focusing on research. This is based on the children's admission to hands-on exhibition space, storytelling techniques were applied in any way children experience exhibits five investigations, by analyzing the spatial movement of the spectator, in terms of storytelling techniques, the type of attribute. In this study, this hands-on exhibition aimed at children when enforcing more effective results can come out to spectators drawn to the conclusion that.

The cause of corrosion failure found in structures or various components operating in severe corrosive environment has been attributed to stress corrosion cracking(SCC) which is resulting from the combined effects of corrosive environments and static tensile stress. Cathodic protection is an electrochemical method of corrosion control that is widely used in marine environment and primarily on carbon steel. A number of criteria are used to determine whether or not a structure is cathodically protected. In practice, -0.8V versus Ag/AgCl is the most commonly used for marine structures. This paper showed the combined effects of cathodic potential and slow, monotonic straining on the tensile ductility and fracture morphology of parents and friction welded joints for SM45C, SCM440 and SM20C steels in syntheic sea water(S.S.W.,pH:8.2). For the parent materials in cathodic potentials, the higher tensile strength is, the more susceptible SCC is. And the welded HAZ is more susceptible than the parent materials.

This research aims to analyze the phenomenon of fusion in K-POP music with J-POP and POP genres. It was achieved by using a CNN model that classifies POP and J-POP genres and then verifying whether J-POP-like style has increased in recent K-POP music. First, the model was trained by 500 songs of each genre: J-POP and POP, which had their vocals removed. Then, six audio signal features were extracted: Spectrogram, Mel-Spectrogram, MFCC, Zero Crossing Rate, Spectral Centroid, and Chromagram. As a result, a CNN model could classify J-POP and POP music with an accuracy of approximately 90%. Afterwards, the model classified 100 K-POP songs per year, from 2020 to 2024. The results show that in 2020 POP-like music accounted for 79%, and J-POP-like music for 21%. In 2024, the proportions shifted, with songs similar to POP-like music taking up 63%, while the ones similar to J-POP-like music - 37%. In conclusion, this study suggests that in addition to the fusion of K-POP with POP music, the fusion with J-POP has increased in recent years.
