  • The current study challenges to suggest an umbrella strategy applied to different type of crisis, which is different from normative principle in crisis communication. The umbrella or comprehensive strategy in this study is identification framing. Identification framing is strategic message for organizational identification, which is close to social identification. The current study employed experimental design manipulating crisis types, crisis response types, and identification framing. The crisis types were internal versus external crisis, crisis responses were denial versus apology, and using identification framing $2{\times}2{\times}2$ factorial design were used. Two hundreds forty students participated in the experiment. The result showed the significant effectiveness of identification framing in different crisis types and crisis responses.

  • The Leaders in organization play various core roles in workers' performance and organizational performance. A leader presents a vision and a direction to enable members to achieve higher performance. Especially, transformational leadership suggests members a strong vision and influences them to have identification with the organization. Based on previous researches, transformational leadership is a close connection to identification with job and organization satisfaction. This study explains the influence of the university professors' transformational leadership on students' university satisfaction and university identification. In this study, the subjects of statistical analysis are Chinese international students studying in Korea. As a result, first, professors' transformational leadership enhanced the level of students' university satisfaction. Second, university identification had a partial mediating influence on the relationship between professors' transformational leadership and students' university satisfaction. Professors' transformational leadership had an influence on the students' identification with their universities. Through this process, students become aware of identification and more satisfied with their universities. As a result of the transformational leadership of the professor, the identification and satisfaction of the international students will be improved and they will be better able to adapt to their study life and achieve high results. The purpose of this study is to emphasize the roles of transformational leadership as a necessary leadership for the successful study abroad life of Chinese students studying in Korea today.

  • System identification is regarded as the most basic technique for structural health monitoring to evaluate structural integrity. Although many system identification techniques extracting mode information (e.g., mode frequency and mode shape) have been proposed so far, it is also desired to identify physical parameters (e.g., stiffness and damping). As for high-rise buildings subjected to long-period ground motions, system identification for evaluating only the shear stiffness based on a shear model does not seem to be an appropriate solution to the system identification problem due to the influence of overall bending response. In this paper, a system identification algorithm using a shear-bending model developed in the previous paper is revised to identify both shear and bending stiffnesses. In this algorithm, an ARX (Auto-Regressive eXogenous) model corresponding to the transfer function for interstory accelerations is applied for identifying physical parameters. For the experimental verification of the proposed system identification framework, vibration tests for a 3-story steel mini-structure are conducted. The test structure is specifically designed to measure horizontal accelerations including both shear and bending responses. In order to obtain reliable results, system identification theories for two different inputs are investigated; (a) base input motion by a modal shaker, (b) unknown forced input on the top floor.

  • Compared with the identification of linear structures, it is more challenging to conduct identification of nonlinear structure systems, especially when the locations of structural nonlinearities are not clear in structural systems. Moreover, it is highly desirable to develop methods of parametric identification using partial measurements of structural responses for practical application. To cope with these issues, an identification method is proposed in this paper for the detection and parametric identification of structural nonlinear restoring forces using only partial measurements of structural responses. First, an equivalent linear structural system is proposed for a nonlinear structure and the locations of structural nonlinearities are detected. Then, the parameters of structural nonlinear restoring forces at the locations of identified structural nonlinearities together with the linear part structural parameters are identified by the extended Kalman filter. The proposed method simplifies the identification of nonlinear structures. Numerical examples of the identification of two nonlinear multi-story shear frames and a planar nonlinear truss with different nonlinear models and locations are used to validate the proposed method.

  • In order to identify a transfer function model with noise, penalty function method has been widely used. In this method, estimation process for possible model parameters from low to higher order proceeds the model identification process. In this study, based on linear estimation method, a new approach unifying the estimation and the identification of ARMAX model is proposed. For the parameter estimation of a transfer function model with noise, linear estimation method by noise separation is suggested instead of nonlinear estimation method. The feasibility of the proposed model identification and estimation method is verified through simulations, namely by applying the method to time series model. In the case of time series model with noise, the proposed method successfully identifies the transfer function model with noise without going through model parameter identification process in advance. A new algorithm effectively achieving model identification and parameter estimation in unified frame has been proposed. This approach is different from the conventional method used for identification of ARMAX model which needs separate parameter estimation and model identification processes. The consistency and the accuracy of the proposed method has been verified through simulations.

  • Purpose: Current research aimed at exploring whether group entitativity and satisfaction to becoming the member of group have positive effects on group identification, and whether group identification has positive effects on within-in-group domain consumption. This research focused on the mediation role of group identification in the effects of the group entitativity and the satisfaction to becoming the member of group on the within-in-group domain consumption. Research design, data, and methodology: We selected Shandong Province as our experimental target group and people living in Shandong province as our respondents. 316 questionnaire data were collected. The structural equation model in AMOS 26 were used to verify hypotheses. Results: First, group entitativity affected group identification positively. Second, satisfaction to becoming the member of group affected group identification positively. Third, group identification positively influenced on the within-in-group domain consumption. Fourth, the group identification played the full mediation roles in the effects of both the group entitativity and the satisfaction on the within-in-group domain consumption. Conclusions: marketers should highlight the group identification with their target group by stimulating the perception of the consumer's group entitativity and satisfied feelings about the group to induce the intent to purchase their brand as within-in-group domain consumption object.

  • This study aims to investigate the impact of green corporate identity and employees' green identification on green business performance of international automobile manufacturers in Thailand. It involves 400 employees from the target study area, using questionnaires to collect data from January to February 2021, with purposive and convenient sampling methods. Data analysis employed structural equation modeling (SEM). The results show that green corporate identity has a significant impact on employees' green personal-social identification and green business performance; meanwhile, employees' green social identification has a significant impact on green business performance. However, employees' green personal identification has a significant impact on green business performance only through employees' green social identification. Green corporate identity can increase the corporate' green business performance via economic, environmental and social aspects through employees' green personal-social identification. The findings suggest that green corporate communication through visual identity, employee behaviors, culture, policy products and services in response to environmental forces and drivers to create the green corporate identity is deemed to systematically work. Furthermore, the findings also suggest that employees' green identification on both personal and social levels can be a significant issue that the managers in automobile manufacturers should pay attention as well.

  • Due to development of IT, various Internet services via the non-face-to-face are increasing rapidly. In the past, the resident registration numbers (RRN) was used a mean of personal identification, but the use of RRN is prohibited by the relevant laws, and the personal identification services using alternative means are activated. According to the prohibition policy of RRN, i-PIN service appeared as an alternative means to identify a person. However, the user's knowledge-based i-PIN service continues to cause fraudulent issuance, account hijacking, and fraud attempts due to hacking accidents. Due to these problems, the usage rate of i-PIN service which performs a nationwide free personal identification service, is rapidly decreasing. Therefore, this paper proposes a technical safety enhancement method for security enhancement in the i-PIN-based personal identification service. In order to strengthen the security of i-PIN, this paper analyzes the encryption key exposure, key exchange and i-PIN authentication model problems of i-PIN and suggests countermeasures. Through the proposed paper, the i-PIN can be expected to be used more effectively as a substitution of RRN by suggesting measures to enhance the safety of personal identification information. Secured personal identification services will enable safer online non-face-to-face transactions. By securing the technical, institutional, and administrative safety of the i-PIN service, the usage rate will gradually increase.

  • This paper proposes a structural damage identification approach based on the power spectral density transmissibility (PSDT), which is developed to formulate the relationship between two sets of auto-spectral density functions of output responses. The accuracy of response reconstruction with PSDT is investigated and the damage identification in structures is conducted with measured acceleration responses from the damaged state. Numerical studies on a seven-storey plane frame structure are conducted to investigate the performance of the proposed damage identification approach. The initial finite element model of the structure and measured acceleration measurements from the damaged structure are used for the identification with a dynamic response sensitivity-based model updating method. The simulated damages can be identified accurately without and with a 5% noise effect included in the simulated responses. Experimental studies on a steel plane frame structure in the laboratory are performed to further verify the accuracy of response reconstruction with PSDT and validate the proposed damage identification approach. The locations of the introduced damage are detected accurately and the stiffness reductions in the damaged elements are identified close to the true values. The identification results demonstrated the accuracy of response reconstruction as well as the correctness and efficiency of the proposed damage identification approach.
