Based on the panel data about 92 countries of Chinese FDI and related variables from 2004 to 2016, the impact on Chinese FDI overseas layout from key factors of China-US Trade Conflict represented by “Three Zeros, Two Stops and One Allowance” were tested using the Hechman two-stage selection model. The empirical research finds that: (1) China's economic development and investment motives are the driving force of Chinese FDI, while host country resource endowment and international investment policies are the attraction of Chinese FDI. (2) Both stages of China's FDI investment selections and investment scale have significant low-cost seeking motives, high-tech seeking motives and natural resources seeking motives from host countries, and significant large-market avoidance trends. (3) In the Chinese FDI investment selection stage, some of host country's international investment policy represented by “Three Zeros, Two Stops and One Allowance” have significant negative impacts, some are influential but not significant; however, in the Chinese FDI investment scale stage, all of host country’s international investment policies have significant positive impacts.

In the process of glycosyltransferase-catalyzed transglycosylation, the synthesis of uridine diphosphate sugars is generally thermodynamically disfavored. This study found that GTBP1 from Bacillus pumilus BF1 displayed the potential to reversely synthesize uridine diphosphate glucose (UDPG, UDP-glucose), which catalyzed the deglycosylation of ponasteroside A and the transglycosylation of phenolic compounds in one-pot reaction. Sequence alignment and phylogenetic tree analysis of GTBP1 and other GTs with reversible glycosylation ability were also implemented. Using solvent engineering strategy, the reaction time in water-organic biphasic was shortened and the conversion was improved. The final conversion of ponasterone A was reached 93.4%, and the final yield of ferulic acid glycoside was 92.7%. Using the fed-batch technology with the coupled reaction, the cumulative product of ponasterone A was about 1.97 g/L, and the level of produced ferulic acid glycoside was about 1.52 g/L. The substrate specificity of the GTBP1 was also confirmed. It implies the diversity of GTBP1's ability to construct UDP cycles.

A combination of multi-physics numerical simulation and experiment was conducted to study the magnetic pulse compaction technology driven by two aluminum tubes of tungsten copper powder. Then, the effects of different process parameters on the density and uniformity of the compact were studied by tuning the thickness of the pack and driver tubes and the gap between them. Results show that the density of compact is the highest when the thickness of the driver tube is 1.0 mm. More energy is consumed for force conduction as the thickness of the pack tube increases. Thus, the density of the compact is the highest when the thickness of the packer tube is 0.8 mm. The speed of the driver tube impacting the pack tube also increases with the rise in the gap. Accordingly, the compaction density with the gap of 1.5 mm is the highest under the same other parameters.

Ponseticlubfoot treatment has become more popular during the last decade because of its high initial correction rate. But the most common problem affecting the long-term successful outcome is relapse of the deformity. Non-compliance with Ponseti brace protocol is a major problem associated with relapse. Although more comfortable braces have been reported to improve the compliance, they all have the same design and no significant changes have been made to the protocols. After refinement in the Ponseti method and emphasizing the importance of brace to parents, the relapse rate has been markedly decreased. Nevertheless, there are patients who do not have any recurrence although they are not completely compliant with the brace treatment, whereas other patients have a recurrence even though they are strictly compliant with the brace treatment. The aim of this article is to review the relapse of clubfoot and the function of the brace and to develop an individualized brace protocol for each patient by analyzing the mechanism of the brace and the biomechanical properties of muscles, tendons, and ligaments.

Purpose – This study aims to analyze the influence of South Korea’s outward foreign direct investment (OFDI) under the effect of both multinational enterprises’ (MNEs) investment motivation and host country institutions. Some suggestions are put forward with regard to South Korean MNEs participating in and integrating into the fierce and changeable world of international market competition. Design/methodology – The basic hypotheses are that MNEs’ investment motivations and the host country’s superior institutions both boost South Korea’s OFDI in those host countries. South Korea’s OFDI is divided into investment choice stage and investment scale stage. A Heckman two-stage selection model is established for empirical analysis, using the panel data of South Korea’s OFDI and related variables, from 2002 to 2019. Findings – (1) The influence on the investment scale of South Korea’s OFDI is more regular and noteworthy than the influence on investment choice. (2) In the investment scale stage, there are obvious motivations to seek markets, labor force and superior technology, but not natural resources. (3) In the investment scale stage, the South Korea’s OFDI is more obviously attracted by the host country’s superior political institutions, economic institutions and legal institutions, but not cultural institutions. Originality/value – The choices of variables and uses of model expand the theoretical basis and empirical method of OFDI research. The results of the empirical study also provide some reference for the transnational investment of South Korean MNEs and the investment policy formulation of the South Korean government.
Current utilization of waste biomass as filler for wood adhesives: A review

Filler is one of the most important additives for wood adhesives. The introduction of filler offers variousfunctions for wood adhesives, such as the increase of initial viscosity, the decrease of permeability, theimprovement of bonding strength, and the reduction of production cost. However, flour, a grain resource,is widely used as a filler that is added to polymers in the production of wood-based panels. As a result, alarge number of edible resources are wasted every year. Waste biomass that biomass residues are abandonedin nature are a promising filler that can be used to replace flour. The utilization of waste biomass asfiller for wood adhesives to prepare wood-based panels not only improves its mechanical strength, butalso reduces formaldehyde emissions. However, most waste biomass shows disappointing prepressingproperties. Advances in the use of waste biomass as an alternative filler for wood adhesives werereviewed. In addition, the current limitations and future prospects of waste biomass were discussed. Recycling waste biomass is a useful way to avoid the enormous amount of waste generated by differentindustries and control environmental pollution. It contributes to the practical development of circulareconomy.
