Linkages among extended service quality, distinct perceived value and satisfaction in the exhibition trust-building process

PurposeThe purpose of this study was to examine the causal relationship between extended service quality including information and communications technology (ICT) and distinct perceived value. This study also examined whether distinct perceived value has different effects on exhibition trust through general attendees' satisfaction.Design/methodology/approachStructural equation modeling was used to examine the causal relationships between the following factors: extended service quality, distinct perceived value, satisfaction and trust.FindingsThe structural relationships between extended service quality, distinct perceived value and satisfaction required to build exhibition trust were empirically confirmed. In particular, ICTs had significant effects on all of the perceived value factors, which reliably supports a conclusion that ICT is a key component of exhibition service quality.Originality/valueRecognizing the significance of ICT, this study has contributed to the field by providing researchers and managers with useful information that not only demonstrates how extended service quality and distinct perceived value independently contribute to satisfaction and interact with each other in doing so but also offers insights for better understanding how trust can be formed in exhibitions. Grasping the distinct preferences for value-oriented activities, understanding the importance of their mediating impacts and expanding the online-offline social networks in which their benefits are promoted and shared can alleviate the uncertainty leading up to exhibition participation while increasing the preemptive transparency of the relationship between quality and value offered by exhibitions.

Total Repair Cost Simulation Considering Multiple Probabilistic Measures and Service Life

In this study, the total maintenance cost for public houses in South Korea was analyzed, and the effect of each repair process on the total maintenance cost was evaluated with probabilistic and deterministic methods. In the probabilistic method, quality of repair materials and construction skills were considered in the variability of extended service life through repair, while the deterministic method considered it by simple summation of repair step. The repair cost was analyzed considering the coefficient of variation (COV) of extended service life, so the reasonable total maintenance cost was able to be evaluated. Since the results through the probabilistic method provided a continuous cost line, a reasonable repair strategy was carried out by simply changing the intended service life of the structure. The repair cost was additionally analyzed with constant COV (0.15) of each repair process for considering various situations. The analysis results with a COV of 0.15 exhibited a slightly higher maintenance cost than those with current COV. The total maintenance costs can be adjusted if the initial repair timing is extended to the largest possible extent for the highest-repair-cost process since the total repair cost is dominated by the process with the highest repair cost.

Prospects for Energy Supply of the Arctic Zone Objects of Russia Using Frost-Resistant Solar Modules

The scientific work is devoted to the prospect of using frost-resistant solar modules with extended service life of various designs for energy supply of infrastructure facilities of the Arctic zone of Russia. The general characteristic of the region under consideration is given, and its energy specifics, directions of energy development based on renewable energy sources are considered. In the work, frost-resistant planar photovoltaic modules and solar roofing panels with an extended service life for power supply of objects are proposed. For simultaneous heat and electrical generation, frost-resistant planar photovoltaic thermal roofing panels and concentrator solar installation with high-voltage matrix solar modules with a voltage of 1000 V and an electrical efficiency of up to 28% are proposed. The considered solar modules have an extended rated power period due to the use of the technology of sealing solar cells with a two-component polysiloxane compound and are able to work effectively at large negative ambient temperatures and large ranges of its fluctuations.
