We investigate the effects of inward foreign direct investment on innovation in Korean industries from 1998 to 2015 by first dividing FDI into greenfield and M&A (mergers and acquisitions). Furthermore, we use the number of patent applications as the proxy of innovation. Our empirical results are as follows: First, inward foreign direct investment has a significantly positive effect on the number of patent applications. This result suggests that the transfer of technology or knowledge through the inward foreign direct investment has a positive impact on innovation in Korean industries. Second, the greenfield investment has a positive impact on patent applications. This result is consistent with Liu and Zou (2008)'s assertion that greenfield investment has a positive impact on innovation by increasing facilities or plants. The M&A investment, however, has no significant effect on patent applications. This result is consistent with Stiebale and Reize (2011) who argue that the host countries do not benefit from technology transfer through M&A investments. In addition, this supports Liu and Zou (2008) and Garcia et al. (2013)'s hypothesis that foreign parent firms do not influence the innovation of host countries by employing strategies to increase market power rather than R&D activities through M&A investments. It is meaningful that this study first analyzes the impact of foreign direct investment on innovation in Korean industries and uses the number of patent applications as a proxy of innovation. Our empirical evidence provides policy implications for innovation and attraction of inward foreign direct investments.

This research work presents 3-D behavior of adjacent structures due to tunnelling induced ground movements by means of field measuring data and nonlinear FEM tunnel analysis. The results of the analytical methods from Mohr-Coulomb model are compared with the site measurement data obtained during the twin tunnel construction. It was found that the location and stiffness of the structure influence greatly the shape and pattern of settlement trough. The settlement trough for Greenfield condition was different from the trough for existing adjacent structures. Therefore the load and stiffness of adjacent structures should be taken into account for the stability analysis of the structures.

This study aims to empirically examine the effect of foreign direct investment (FDI) and corruption on the development of public-service sectors in 10 ASEAN countries. It then investigates whether this relationship is different between two FDI compositions including greenfield FDI and FDI in the form of cross-border merger and acquisitions (M&As). Using a panel database of 10 ASEAN countries during the period 1996-2015 from various sources including the World Development Indicators of the World Bank and UNCTAD, we first find that FDI strongly and positively contributes to the development of the public-service sectors in the recipient nations, except for the electricity sector. However, we show that this relationship is dependent on the type of FDI modes of entry. Specifically, while greenfield investment exerts a beneficial influence on the development of telecommunication and transportation sectors, cross-border M&A has no effect on these sectors, perhaps because of the distinct differences among three public service sectors. Finally, we found that in a highly corrupt environment, aggregate FDI might have no influence on all three public-service sectors, possibly because the two contradictory influences of the interaction terms between corruption and two FDI sub-types seem to cancel each other out.

Vertical soil stress near a pile subjected to negative skin friction (NSF) may be reduced due to shear transfer at the pile-soil interface. A three-dimensional finite difference analysis has been performed to clarify the influence of vertical and horizontal stress reductions on the pile behavour. In addition, a simple equation has been proposed to estimate vertical stress reduction of the soil near the pile. The vertical and horizontal stresses are reduced by substantial amount compared to corresponding stress components at the Greenfield condition. The horizontal extent of vertical stress reduction of the soil near the pile is rather limited to about up to 4-8 D, where D is the pile diameter. The findings from the current research indicate that widely used $\beta$-method may result in over-estimation of dragload (compressive force on piles due to NSF) and hence stress reduction needs to be incorporated in the original equation.

Urban tunnelling need to consider not only the stability of tunnel itself but also the ground movement regarding adjacent structures. This paper present 3-D behavior of adjacent structures due to tunnelling induced ground movements by means of field measuring data and nonlinear FEM tunnel analysis.

The purpose of this study is to research the investment environment of Vietnam and analyze the actual investment state of Korean enterprises in Vietnam and seek for the points at issue. In general, the investment environment in Vietnam shows both a positive side and negative side. However Vietnamese market is a attractive one as ever for direct investment of Korean enterprises considering their constant economy growth, investment increase of foreign company for Vietnam, China risk. And the point at issue in investment of Korean Enterprises is as follows. That is, inclining to manufacturing, preference of independence investment, small-sized investment by small and medium enterprises, preference of greenfield investment, restricted purpose of investment, insufficiency of infrastructure for logistics, electric power, legal system. The results of the study indicate mainly that the investment of Korean enterprise into Vietnam needs a switchover of the third service trade-tertiary industry, collaboration with Vietnamese enterprise through joint venture investment, a large-scale investment for Vietnam domestic market and neighboring countries' market, practical use of M&A with existing Vietnamese enterprise and diverse purpose for investment.

Double mitral valve orifice is an unusual congenital abnormality, and is rarely of clinical importance. That abnormality not produce hemodynamic deficits, but it has been associated with other congenital heart diseases, especially atrioventricular canal defects, and so it is surgically important condition. After the first report by M.S. Greenfield in 1876, there are only a few reported cases all over the world. We experienced two cases of double mitral valve orifice with atrioventricular canal defect. The small accessory mitral orifice was placed in anterior mitral leaflet as a hole type in both cases. The A-V canal defects are corrected with a one patch technique, but the accessory orifices are left unclosed because there were no mitral regurgitations through the orifice. On the 4th postoperative day, the patients have been performed echocardiography; both had no mitral regurgitation. Both of patients are now being follow-up and we find no specific problems. A small accessory mitral orifice may be left unclosed and rarely produce significant regurgitation, conclusively.

This paper examine the changing ecosystems in Malaysia, starting with the government policy driven greenfield cluster of Cyberjaya, which is part of the Multimedia Super Corridor (MSC) mega project. In this context of an emerging economy, predominantly production oriented, the role of the government was crucial with respect to implementing policies and building infrastructure for the ecosystems. First, the roles played by the cluster development agency, universities, and industry are explained. As the cluster developed, this paper, taking an entrepreneurial ecosystem approach, explores how some actors evolved and changed their roles to become catalyst organisations established for the cluster now serving nationwide. This was followed by the emergence of new actors in the ecosystems, for example, knowledge intermediaries, and new roles for universities. In addition to actors such as universities and industry, this paper recognizes the emergence of media organisations as new actors in the entrepreneurial ecosystems in Malaysia.

The containment building Kori Unit 1 may require sequential steps for full decommissioning. This study assumes that the containment building is to be used as an auxiliary building that handles nuclear power systems and materials during decommissioning before conversion into a greenfield. Through the derivation of guidelines and dose evaluation, it was confirmed whether the radiation workers were satisfied with the ALARA decision. The specific modeling of the external radiation exposure was performed based on the facility investigation procedures. The external radiation specific derived concentration guideline levels (DCGLs) for radiation workers in containment building were obtained using the RESRAD-BUILD code and were applied to the VISIPLAN 3D ALARA Planning Tool code to calculate the working dose and check worker safety. The derivation of site-specific and realistic DCGLs and dose evaluation via 3D modeling can contribute to the scenario development for the decommission and remediation of containment building.
