The aim of this study is to investigate the role of employee engagement as a mediator between the High-Performance Work System and the Service-Oriented Organizational Citizenship Behavior (Service-Oriented OCB). Furthermore, work-life balance as a moderator, the impact Service-Oriented OCB on customer satisfaction will be investigated. This study employs a quantitative methodology for which questionnaires were distributed to sixty restaurants in Karachi, and a sample of 418 responses was collected for structural equation modeling analysis. Smart PLS software was used to analyze the structure model. The results show that HPWS has a positive impact on Service-Oriented OCB. It is assumed that the role of work engagement as a mediator between HPWS and Service-Oriented OCB is significant. This study found that Service-Oriented OCB has a positive impact on customer satisfaction. Work-life balance was also found to have a moderating influence. The findings confirmed the black box mechanism and the HPWS procedures in restaurants. This study suggests implementing effective HPWS practices to influence employees' work engagement, which leads to Service-Oriented OCB and employees being able to optimize their performance to influence customer satisfaction. The study contributes to the existing body of knowledge in human resource management.

In A institute, project managers present quarterly project performance report according to institute's law. In quarterly project performance report, progress of project performance and budget expended should be written. Progress of project performance and progress of budget expended are key management factors in A institute. Because financial database system Is already constructed, progress of budget expended is got from information system. But the progress of project performance that project manager estimate subjectively can not be judged of its correctness because there is not project management information system that is able to calculate the progress of project performance systematically. In this study, we present the project management system assign all activities to every project participator according to their work share rate using WBS(Work Breakdown Structure) and calculate the progress of project performance systematically Also we construct project management information system for above project management system implementing.

KPI, an indicator that measures the performance of factors that contribute to achieving strategies of individuals or organizations, is used a lot to analyze the performance of construction work. Construction work consists of individual construction types with different characteristics such as progress method, scale, and input resources, but currently, KPIs for performance analysis of individual construction types are lacking. Therefore, this study aims to obtain and analyze data for establishing construction performance analysis KPIs during construction work to prepare the basis for the creation of future construction KPIs. Preliminary KPIs for earthwork performance analysis selected through this study are expected to be the basis for deriving preliminary KPIs for other individual construction types.

This paper presents the new cascade liquefaction cycles using $CO_2-C_2H_6-N_2$ and $CO_2-N_2O-N_2$. The performance of the cascade liquefaction cycles with respect to temperature differences in the LNG heat exchangers is analyzed using HYSYS software and then compared the performance of these cycles with phillips optimized cascade liquefaction cycle. The coefficient of performance of the new liquefaction cycles considered in this study decreases with the temperature differences in the LNG heat exchangers, but the compressor work, expander work and heat capacity in the LNG heat exchanger increases, respectively. From the comparison of performance of three cycles, the cascade liquefaction cycles using $CO_2-C_2H_6-N_2$ showed the highest COP. And the cycles using $CO_2-C_2H_6-N_2$ and $CO_2-N_2O-N_2$ presented the second and third highest COP, respectively. In the view of performance, the optimized cascade liquefaction cycle using $C_3H_8-C_2H_4-C_1H_4$ yields much better COP. But, in the environment view, it is found that the cascade liquefaction cycle using $CO_2-C_2H_6-N_2$ shows favorable characteristics.

Demand is increasing for large, high-rise, and complex buildings, which is leading to advances in the development of high-performance structural systems. In this context, precast concrete (PC) technology has received a large amount of attention owing to its benefits in terms of schedule reduction, high quality, and easy installation. In addition, advanced methodologies that improve the PC performance by the addition of various materials have recently been reported. Research on analyzing the effects of such high-performance PC on the construction process and productivity is very limited. This makes it difficult for decision-makers to apply PC to particular projects. Thus, the aim of this research was to analyze the work productivity of the high-performance PC slab installation process by using a construction simulation tool to resolve critical issues. In this study, a real construction project that adopted PC slab installation work was analyzed, and a sensitivity analysis was performed to confirm the reliability of the analysis results.
