Property Rights, Development, and Financial Markets in South Korea
Wolfgang Veit 서울대학교 경제연구소 1989 Seoul journal of economics Vol.2 No.3
Property-rights describe the rights individuals have over material and immaterial goods. From the point of view of the property rights approach, a financial market is primarily a market for "rights to exchange something (money) for goods". Efficiency in this market depends largely on the information available to intermediaries like banks and other financial institutions. Regulation of financial markets was at the heart of Korea's economic strategies for more than two decades. Here, the distribution of property-rights by the government was supporting export industries and at the same time hindering balanced development of the economic structure.

<P><B>Abstract</B></P> <P>Src family kinases (SFKs) are a family of protein tyrosine kinases containing nine members: Src, Lyn, Fgr, Hck, Lck, Fyn, Blk, Yes, and Ylk. Although SFK activation is a major immediate signaling event in LPS/Toll-like receptor 4 (TLR4) signaling, its precise role has remained elusive due to various contradictory results obtained from a certain SFK member-deficient mice or cells. The observed inconsistencies may be due to the compensation or redundancy by other SFKs upon a SFK deficiency. The chemical rescuing approach was suggested to induce temporal and precise SFK activation in living cells, thereby limiting the chance of cellular adaption to a SFK-deficient condition.</P> <P>Using the rescuing approach, we demonstrate that restoring SFK activity not only induces tyrosine phosphorylation of TLR4, but also inhibits LPS-induced NFκB and JNK1/2 activation and consequently suppresses LPS-induced cytokine production. TLR4 normally recruits TIR domain-containing adaptors in response to LPS, however, temporally restored SFK activation disrupts the LPS-induced association of MyD88 and Mal/Tirap with TLR4. Additionally, using kinase-dead SFK-Lyn (Y397/508F) and constitutively active SFK-Lyn (Y508F), we found that the kinase-dead SFK inhibits TLR4 tyrosine phosphorylation with reduced binding affinity to TLR4, while the kinase-active SFK strongly binds to TLR4 and promotes TLR4 tyrosine phosphorylation, suggesting that SFK kinase activity is required for TLR4 tyrosine phosphorylation and TLR4-SFK interaction.</P> <P>Together, our results demonstrate that SFK activation induces TLR4 tyrosine phosphorylation, consequently dissociating MyD88 and Mal/Tirap from TLR4 and inhibiting LPS-induced inflammatory responses, suggesting a negative feedback loop regulated by SFK-induced tyrosine phosphorylation in TLR4.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
ETHICAL BEHAVIOR AND STANDARDS OF INVESTMENT PROFESSIONALS IN SINGAPORE
H Kent Baker,E Theodore Veit People&Global Business Association 1997 Global Business and Finance Review Vol.2 No.1
This study reports the results of a survey about the ethical behavior of securities analysts and portfolio managers in Singapore and compares the responses of investment professionals in Singapore and North America. The evidence shows that most respondents from Singapore view investment professionals as "moderately ethical." They also believe that ethical standards among investment professionals in Singapore have improved during the past decade and are likely to improve over the next ten years. Respondents also believe senior management plays a key role in providing training and education for investment professionals. The most commonly reported ethical or legal violations are trading based on inside information or communicating inside information. The most important deterrent to unethical or illegal behavior is concern about government sanctions. A comparison of the responses from investment professionals in Singapore and North America shows many significant differences, which largely may be explained by different cultural and regulatory environments.
Mechanical robustness of AREVA NP's GAIA fuel design under seismic and LOCA excitations
Brian Painter,Brett Matthews,Pierre-Henri Louf,Herve Lebail,Veit Marx 한국원자력학회 2018 Nuclear Engineering and Technology Vol.50 No.2
Recent events in the nuclear industry have resulted in a movement towards increased seismic and LOCAexcitations and requirements that challenge current fuel designs. AREVA NP's GAIA fuel design introducesunique and robust characteristics to resist the effects of seismic and LOCA excitations. For demanding seismic and LOCA scenarios, fuel assembly spacer grids can undergo plastic deformations. These plastic deformations must not prohibit the complete insertion of the control rod assembliesand the cooling of the fuel rods after the accident. The specific structure of the GAIA spacer gridproduces a unique and stable compressive deformation mode which maintains the regular array of thefuel rods and guide tubes. The stability of the spacer grid allows it to absorb a significant amount ofenergy without a loss of load-carrying capacity. The GAIA-specific grid behavior is in contrast to the typical spacer grid, which is characterized by abuckling instability. The increased mechanical robustness of the GAIA spacer grid is advantageous inmeeting the increased seismic and LOCA loadings and the associated safety requirements. The uniqueGAIA spacer grid behavior will be incorporated into AREVA NP's licensed methodologies to take fullbenefit of the increased mechanical robustness

Background: Classical acupuncture is being used in the treatment of rheumatoid arthritis (RA). To explore the biological response to acupuncture, a network-based analysis was performed on gene expression data collected from an animal model of RA treated with acupuncture.Methods: Gene expression data were obtained from published microarray studies on blood samples from rats with collagen induced arthritis (CIA) and non-CIA rats, both treated with manual acupuncture. The weighted gene co-expression network analysis was performed to identify gene clusters expressed in association with acupuncture treatment time and RA status. Gene ontology and pathway analyses were applied for functional annotation and network visualization.Results: A cluster of 347 genes were identified that differentially downregulated expression in association with acupuncture treatment over time; specifically in rats with CIA with module-RA correlation at 1 hour after acupuncture (-0.27; <i>p</i> < 0.001) and at 34 days after acupuncture (-0.33; <i>p</i> < 0.001). Functional annotation showed highly significant enrichment of porphyrin-containing compound biosynthetic processes (<i>p</i> < 0.001). The network-based analysis also identified a module of 140 genes differentially expressed between CIA and non-CIA in rats (<i>p</i> < 0.001). This cluster of genes was enriched for antigen processing and presentation of exogenous peptide antigen (<i>p</i> < 0.001). Other functional gene clusters previously reported in earlier studies were also observed.<br>Conclusion: The identified gene expression networks and their hub-genes could help with the understanding of mechanisms involved in the pathogenesis of RA, as well understanding the effects of acupuncture treatment of RA.
