In modal analysis, the mode shape reflects the vibration characteristics of the structure, and thus it is widely performed for finite element model updating and structural health monitoring. Generally, the acceleration-based mode shape is suitable to express the characteristics of structures for the translational vibration; however, it is difficult to represent the rotational mode at boundary conditions. A tilt sensor and gyroscope capable of measuring rotational mode are used to analyze the overall behavior of the structure, but extracting its mode shape is the major challenge under the small vibration always. Herein, we conducted a feasibility study on a multi-mode shape estimating approach utilizing a single physical quantity signal. The basic concept of the proposed method is to receive multi-metric dynamic responses from two sensors and obtain mode shapes through bridge loading test with relatively large deformation. In addition, the linear transformation matrix for estimating two mode shapes is derived, and the mode shape based on the gyro sensor data is obtained by acceleration response using ambient vibration. Because the structure's behavior with respect to translational and rotational mode can be confirmed, the proposed method can obtain the total response of the structure considering boundary conditions. To verify the feasibility of the proposed method, we pre-measured dynamic data acquired from five accelerometers and five gyro sensors in a lab-scale test considering bridge structures, and obtained a linear transformation matrix for estimating the multi-mode shapes. In addition, the mode shapes for two physical quantities could be extracted by using only the acceleration data. Finally, the mode shapes estimated by the proposed method were compared with the mode shapes obtained from the two sensors. This study confirmed the applicability of the multi-mode shape estimation approach for accurate damage assessment using multi-dimensional mode shapes of bridge structures, and can be used to evaluate the behavior of structures under ambient vibration.

Recently, global luxury fashion brands such as Gucci, Saint Laurent, and Louis Vuitton have been showing special interest in Korean contemporary artists and actively collaborating with them. This can be said to be a new change that is distinguished from previous collaborations of fashion brands. Therefore, this study investigated the cases of collaboration between global luxury fashion brands and Korean contemporary artists, and analyzed the types and characteristics to examine the trends and characteristics and draw meaning. As a result, fashion brands combine the characteristics of Korean art works of various genres with the brand concept and pursued values to create new sensibility and high value-added products. It can be seen that the intention was to prepare a place to draw out. In addition, it was found that collaboration was also utilized in terms of marketing so that domestic customers could visit the brand store with a sense of familiarity by utilizing Korea's artistic and cultural sentiments. Based on the results of this study, we intend to provide basic data for the development of creative contents for various collaborations between fashion and art that can help develop the modern fashion industry.

Countries around the world have recognized the importance of personal information protection and have discussed protecting the rights of data subjects in various forms such as laws, regulations, and guidelines. PbD (Privacy by Design) is one of the concepts that are commonly emphasized as a precautionary measure for the protection of personal information, and it is starting to attract attention as an essential element for protecting the privacy of information subjects. However, the concept of PbD to prioritize individual privacy in system development or service operation in advance is still only at the declarative level, so there is relatively little discussion on specific methods to implement it. Therefore, this study discusses which principles and rights should be prioritized to implement PbD based on the basic principles of GDPR and the rights of data subjects. This study is meaningful in that it suggests a plan for the practical implementation of PbD by presenting the privacy considerations that should be prioritized when developing systems or services in the domestic environment.

The concept of library is newly interpreted and designed under the environment of U-City. The basic notion of the library should not changed its kernel nevertheless, the new technologies like ubiquitous computing services are applied to the library, which functions in terms of information services, continuous learning programs and communities of practice(CoP). The library is fit for any technologies or environments as organism. Actually the library has been shown in terms of new information technologies with the changes of the times. It leads to comprehend the library as its appearance not as it is. The libraries including even cities have evolved toward ubiquitous(computing) environment. On the other words, the libraries have sought ubiquitous at the past, now they are still chasing it.

Considering the contribution of industrial facilities to the national economy, securing operability against earthquakes is very important. However, the basic concept of current seismic design mainly allows ductile behavior of facilities against large-scale earthquakes and only considers structural safety for the purpose of preventing collapse. In order to secure the operability of industrial facilities, the level of seismic performance to maintain operability may vary depending on the structural behavior characteristics of the industrial facility, and a seismic design method is needed to satisfy this. In this study, a ground storage tanks Nonlinear seismic behavior characteristics(R-μ-T) were analyzed through nonlinear response history analysis, and based on this, a new reliability-based, performance-based seismic design method was proposed.
