The OECD members included Japan and the Republic of Korea, while the seven non-OECD nations were China, India, Indonesia, Malaysia, Pakistan, the Philippines, and Thailand. Healthcare systems efficiency was analyzed over the period 1996– 2017. To assess the effectiveness of healthcare expenditure of each group of countries, the two-way fixed effects model (country- and year effects) was used.Results: Quality of governance and current health expenditure determine healthcare system performance. Population density and urbanization are positively associated with a healthy life expectancy in the non-OECD Asian countries. In this group, unsafe water drinking has a statistically negative effect on healthy life expectancy. Interestingly, only per capita consumption of carbohydrates is significantly linked with healthy life expectancy. In these non-OECD Asian countries, unsafe water drinking and per capita carbon dioxide emissions increase infant mortality. There is a strong negative association between GDP per capita and infant mortality in both sub-samples, although its impact is far larger in the OECD group. In Japan and South Korea, unemployment is negatively associated with infant mortality.Conclusion: Japan outperforms other countries from the sample in major healthcare performance indicators, while South Korea is ranked second. The only exception is per capita carbon dioxide emissions, which have maximal values in the Republic of Korea and Japan. Non-OECD nations’ outcomes were led by China, as the largest economy. This group was characterized with substantial improvement in efficiency of health spending since the middle of the 1990s. Yet, progress was noted with remarkable heterogeneity within the group.Keywords: Asia, health expenditure, healthy life expectancy, infant mortality, nutrition, population health outcomes

Research was conducted to examine the configuration of dislocations in lateral overgrowth GaN films. Transmission electron microscopy and cathodoluminescence were used to investigate the microstructure of sublimation lateral overgrowth GaN. Results demonstrate that the dislocations also affect the yellow emission and not just the band edge emission. The dislocations were also shown to propagate laterally in the overgrowth region.

The selective overgrowth approach was employed to grow bulk-like GaN layers by sublimation technique. To determined the lateral growth mechanisms in sublimation, the microstructure of selectively regrown GaN was investigated by cathodoluminescence, scanning electron microscopy and transmission electron microscopy. The effect owing to the reduction of dislocation density with different mask materials as well as the extension of the threading dislocation in the region of laterally regrown GaN are also analyzed.
