Mg2X (X = Si, Sn) thermoelectric materials are promising materials for converting solar-thermal energy to electricity. To investigate the effects of non-stoichiometric compositions and Ag-doping on the thermoelectric properties of Mg2Sn, Mg2Sn thermoelectric materials were synthesized via...

A thermoelectric material with sufficient performance at high temperatures is a key factor for thermoelectric generation from solar-thermal energy (I. R. radiation). In this study, we analyzed CoSb3 skutterudite compounds as a thermoelectric material at high temperatures and synthesized filled...

The aim of this literature review is to identify whether differences between welfare regimes can manifest diverse consequences for the health effects of insecure and precarious employment, as well as to address challenging issues and implications for future research.

The Fe–Al–X(Cu, Ni, Ti) composites reinforced with graphite particles were fabricated employing the powder metallurgy process for slide bearing applications. In all samples, graphite particles of 6 wt.% were added. Elemental powders were mixed to specific compositions with a powder...

Micro-spur gears were fabricated by powder injection–compression molding and micro-two-step gears were produced through stacking and sintering of the green parts. Shrinkage of micro-gears by sintering was larger in teeth and with increase of compression pressure, shrinkage was decreased due to...

Employment relations, as a theoretical framework for social class, represent a complementary approach to social stratification. Employment relations introduce social relations of ownership and control over productive assets to the analysis of inequalities in economic (e.g., income), power...

This study examines and explains the gender disparity in health despite rapid modernization in South Korea where the social structure is still based on traditional gender relations. A nationally representative sample of 2897 men and 3286 women aged 25-64 from the 2001 Korean National Health and...

In light of escalating job insecurity due to increasing numbers of nonstandard workers, this study examined the association between nonstandard employment and mental health among South Korean workers. We analyzed a representative weighted sample of 2086 men and 1194 women aged 20-64 years, using...
