Purpose: This study aims to investigate the linkages among cross-channel integration capability (CCI), showrooming, webrooming, and customer value of retail enterprises. From the literature review, this research proposes the research model on the direct impact of showrooming and webrooming on customer value as well as the indirect impact of cross-channel integration capability on customer value which is mediated by both showrooming and webrooming of retail enterprises. Research design, data, and methodology: By conducting a survey of 304 consumers in the five biggest retailers in Hanoi-Vietnam from mid-September 2021 to the end of November 2021, the PLS-SEM was used to test the hypotheses. Results: The research results reveal the favorable impact of (CCI) on improving showrooming and webrooming, and the important role of developing both showrooming and webrooming in bringing more value to the customer of retail enterprises. The findings also express that showrooming and webrooming acts mediating role in the favorable relationship between (CCI) and customer value of retailers. Conclusions: This research clarifies the positive impact of (CCI), showrooming, and webrooming on customer value. In addition, this study suggests practical implications for retail managers to provide more value for customers by enhancing (CCI) and developing both showrooming and webrooming.

This study examines the effect of customer experience management capability of a bank and job satisfaction and customer orientation of the frontline employee in bank. The proposed research model and developed hypotheses were tested using structural equations modeling based on data collected from 321 employees working in banks. The results of the study confirm the positive effects of employee training, employee empowerment, employee evaluation, cross functional work of customer experience management capability is job satisfaction and customer orientation. But channel integration is not supported job satisfaction and customer orientation. Performance management influenced customer orientation through job satisfaction. The study provides On a theoretical level valuable insights into the customer experience management competency at the organizational unit and but there is also a limitation that firms the is limited.

MARS-KS, a domestic regulatory confirmatory code of Republic of Korea, had been developed by integrating RELAP5/MOD2 and COBRA-TF. The integration of COBRA-TF allowed to extend the capability of MARS-KS, limited to one-dimensional analysis, to multi-dimensional analysis. The use of COBRA-TF was mainly focused on subchannel analyses for simulating multi-dimensional behavior within the reactor core. However, this feature has been remained as a legacy without ongoing maintenance. Meanwhile, MARS-KS also includes its own multidimensional component, namely MULTID, which is also feasible to simulate three-dimensional convection and diffusion. The MULTID is capable of modeling the turbulent diffusion using simple mixing length model. The implementation of the turbulent mixing is of importance for analyzing the reactor core where a disturbing cross-sectional structure of rod bundle makes the flow perturbation and corresponding mixing stronger. In addition, the presence of this turbulent behavior allows the secondary transports with net mass exchange between subchannels. However, a series of assessments performed in previous studies revealed that the turbulence model of the MULTID could not simulate the aforementioned effective mixing occurred in the subchannel-scale problems. This is obvious consequence since the physical models of the MULTID neglect the effect of mass transport and thereby, it cannot model the void drift effect and resulting phasic distribution within a bundle. Thus, in this study, the turbulence mixing model of the MULTID has been improved by means of the inter-channel mixing model, widely utilized in subchannel analysis, in order to extend the application of the MULTID to small-scale problems. A series of assessments has been performed against rod bundle experiments, namely GE 3X3 and PSBT, to evaluate the performance of the introduced mixing model. The assessment results revealed that the application of the inter-channel mixing model allowed to enhance the prediction of the MULTID in subchannel scale problems. In addition, it was indicated that the code could not predict appropriate phasic distribution in the rod bundle without the model. Considering that the proper prediction of the phasic distribution is important when considering pin-based and/or assembly-based expressions of the reactor core, the results of this study clearly indicate that the inter-channel mixing model is required for analyzing the rod bundle, appropriately.

The Incheon Bridge, which was opened to the traffic in October 2009, is an 18.4 km long sea-crossing bridge connecting the Incheon International Airport with the expressway networks around the Seoul metropolitan area by way of Songdo District of Incheon City. This bridge is an integration of several special featured bridges and the major part of the bridge consists of cable-stayed spans. This marine cable-stayed bridge has a main span of 800 m wide to cross the vessel navigation channel in and out of the Incheon Port. In waterways where ship collision is anticipated, bridges shall be designed to resist ship impact forces, and/or, adequately protected by ship impact protection (SIP) systems. For the Incheon Bridge, large diameter circular dolphins as SIP were made at 44 locations of the both side of the main span around the piers of the cable-stayed bridge span. This world's largest dolphin-type SIP system protects the bridge against the collision with 100,000 DWT tanker navigating the channel with speed of 10 knots. Diameter of the dolphin is up to 25 m. Vessel collision risk was assessed by probability based analysis with AASHTO Method-II. The annual frequency of bridge collapse through the risk analysis for 71,370 cases of the impact scenario was less than $0.5{\times}10^{-4}$ and satisfies design requirements. The dolphin is the circular sheet pile structure filled with crushed rock and closed at the top with a robust concrete cap. The structural design was performed with numerical analyses of which constitutional model was verified by the physical model experiment using the geo-centrifugal testing equipment. 3D non-linear finite element models were used to analyze the structural response and energy-dissipating capability of dolphins which were deeply embedded in the seabed. The dolphin structure secures external stability and internal stability for ordinary loads such as wave and current pressure. Considering failure mechanism, stability assessment was performed for the strength limit state and service limit state of the dolphins. The friction angle of the crushed stone as a filling material was reduced to $38^{\circ}$ considering the possibility of contracting behavior as the impact.
