Standard blockwise empirical likelihood (BEL) for stationary, weakly dependent time series requires specifying a fixed block length as a tuning parameter for setting confidence regions. This aspect can be difficult and impacts coverage accuracy. As an alternative, this paper proposes a new...

In this paper, we consider the problem of determining the optimal block size for a spatial subsampling method for spatial processes observed on regular grids. We derive expansions for the mean square error of the subsampling variance estimator, which yields an expression for the theoretical...

This study investigated the effect of the built-in volume ratio of an expander on the performance of a dual-loop Rankine cycle system for the engine waste heat recovery of a vehicle. Varying vehicle operating conditions can cause a positive displacement expander to operate in both under- and...

To strengthen industrial competitiveness and productivity, the digital transformation is necessary. In addition, new technologies such as artificial intelligence (AI), robots and big data, among others, create new industries and are poised to increase demand for high-skilled workers. The Korean...

The purpose of the minimum wage is to stabilize a worker’s life and improve the quality of the labor force by guaranteeing a minimum level of wages, thereby contributing to the sound development of the national economy (MINIMUM WAGE ACT.)The Minimum Wage Council (MWC) consists of 27 members...

Effective industrial workforce policies that facilitate the supply and demand of labor are crucial, especially during times of industrial transition. We are living through three such transitions, with the ongoing green transformation, digital transformation, and rapidly changing domestic and...

The expansion of global value chains (GVCs) and production automation have brought about changes in the production processes. Such changes enable firms to concentrate on and specialize in highly efficient and value-added tasks, and as a result, they are likely to improve their management...
