Research addressing international new ventures' social responsibility activities is scarce. Specifically, researchers have little account for the effects of an international new venture's social responsibility efforts on the outcomes of relationships with local customers in emerging economies. Against this background, we attempt to extend the boundaries of an understanding of the effects of international new ventures' social responsibility engagement on local customers' loyalty through customer trust and customer identification in emerging economies. Based mainly on the stakeholder theory and the relationship marketing theory, our study conceptualize two facets of international new ventures' social responsibility efforts: ethical and philanthropic corporate social responsibility engagement. In addition, we identify positive customer relationship-building mechanisms for each facet. Furthermore, our study presents an empirically testable propositions that would explain how international new ventures' social responsibility efforts influence the outcomes of relationships with local customers in emerging economies. Finally, this manuscript provides a discussion of the present study' implications for theory and practice and limitations that naturally lead to future research on international new ventures' social responsibility activities in developing economies.

It has been well known that the use of Saccharomyces cerevisiae can cause fungemia in critically ill patients and flavone shows an antimicrobial effect on S. cerevisiae. Therefore, we have investigated the activities of thirteen flavone analogues on S. cerevisiae in our studies. Because flavonoids including flavones have antioxidative effects, we try to carry out the activity studies of flavone analogues in vitro and in vivo. In addition, the relationships between the structures of flavone analogues and their biological activities, such as antimicrobial and antioxidative effects, were elucidated using Comparative Molecular Field Analysis calculations. Of the flavone analogues tested here, 3,2'-dihydroxyflavone showed both good antimicrobial and antioxidative activities.

The objective of this study was to investigate the biological activities of fermented mugworts and their effects on the lipid metabolism in hyperlipidemia-induced rats. The proximate compositions of two kinds of mugwort, Artemisia capillaris Thumberg and Artemisiae asiaticae Nakai, were compared before and after fermentation. In both types of mugwort crude protein and amino nitrogen contents markedly increased with fermentation. Thrombolytic activity determined from the size of the clear zone on a fibrin plate was higher for the Artemisiae asiaticae Nakai, especially in the fermented sample. Antioxidative activity according to DPPH(1,1-diphenyl-2-picrylhydrazyl) radical scavenging effects was higher for Artemisia capillaris Thumberg but no significant differences were found between the samples after fermentation. The body weights of hyperlipidemia-induced rats that were fed the mugworts for 4 weeks were lower than those of the control group. In all the mugwort-fed rats serum total cholesterol and LDL-cholesterol levels remarkably decreased. Furthermore the fermented mugworts were found to be more effective at decreasing triglyceride (TG) levels. It is also noteworthy that the highest HDL-cholesterol levels were observed in the rats treated with the fermented Artemisiae asiaticae Nakai. And fatty liver weights were higher in the rats fed Artemisia capillaris Thumberg. In conclusion the feeding of fermented Artemisiae asiaticae Nakai was effective for increasing thrombolytic activity and HDL-cholesterol levels as well as reducing TG levels in rats.

Effects of rare earth metals addition and aging treatment on corrosion resistance and mechanical properties of super duplex stainless steels were investigated using optical/SEM/TEM metallographic examination, an X-ray diffraction test, a potentiodynamic anodic polarization test and a tensile test. The performance of the experimental alloy with 0.32% REM addition was compared with commercial super duplex stainless steel such as SAF 2507 when they were exposed to solution annealing heat treatment and aging treatment. The corrosion resistance in CF environments and mechanical properties of the experimental alloy were found superior to those of the commercial duplex stainless steel. The REM with larger atomic radii than those of Cr, Mo and W may fill vacancies inside the matrix and around the grain boundaries, retarding formation of harmful intermetallic σ and χ phases. In addition, fine REM oxides/oxy-sulfides (1-3㎛) seemed to enhance the retardation effects. With REM additions, strength and ductility increased due to the phase and grain refinement caused by fine REM oxides and oxy-sulfides.

본 연구의 목적은 정신장애를 가진 어머니의 심리증상과 자녀의 탄력성과의 관계에서 어머니가 지각하는 모자관계가 매개효과로 작용하는지를 알아보는 것이다. 연구대상은 만7세 이상 15세 이하의 자녀를 양육하고 있는 정신장애를 가진 어머니 255명이었다. 연구결과, 어머니의 심리증상과 모자관계는 자녀의 탄력성에 직접 영향을 미치는 것으로 나타났다. 또한, 모자관계의 매개효과를 알아본 결과, 어머니의 심리증상과 자녀의 탄력성 사이에서 모자관계가 부분 매개효과로 작용하는 것으로 나타났다. 이러한 결과를 통하여 자녀의 탄력성에 대한 실천에 있어서, 어머니의 심리적 어려움의 보호요인으로 나타난 모자관계에 초점을 둔 개입의 필요성이 제기되었다.

본 논문은 국가 경제의 동맥역활을 하는 물류산업에 초점을 맞추고 권역별 물류산업의 특징과 경제적 파급효과를 분석하였다. 이를 위하여 물류산업을 중심으로 6개 권역(수도권, 강원권, 충청권, 전라권, 경북권, 경남권)으로 구분된 지역산업연관표(MRIO표)를 이용하여 지역별, 산업별로 경제권에 대한 분석을 수행하였다. 연구의 목적에 맞게 기존의 산업연관표를 중심으로 29개 부문으로 재구성하였고, 총산출액 비교 및 외생화 방법을 이용하여 생산유발효과, 공급지장효과, 전후방연쇄효과 등을 분석하였다. 분석결과, 물류산업은 생산유발효과보다 공급지장효과가 큰 산업으로 나타났고, 지역간의 거래보다는 지역내의 거래가 상대적으로 많은 것으로 나타났다. 그 밖에 수도권 물류산업은 중간수요적 원시산업 특성을 가지는 관계로 파급효과가 미약한 것으로 나타났고, 경남권의 자동차 및 석유화학, 전라권의 석유화학 등에 미치는 물류산업의 파급효과가 큰 것으로 나타났다.

Purpose The purpose of this study is to verify motivations of corporate Facebook usage and to examine the impacts of usage motivations on brand attachment, trust and loyalty. Design/methodology/approach A conceptual model is developed based on Self-determination theory(SDT) and the previous studies. We conducted a web survey with a convenient sample of 121 Facebook users who clicked "Like" button on the corporate Facebook pages. Findings The followings are the findings of the study. First, intrinsic motivation(Entertainment) turned out to have positive effects on brand attachment. Second, extrinsic motivation(information exchange) turned out to have positive effects on brand trust. Third, brand attachment turned out to have positive effects on brand loyalty. These findings provide a valuable basis for constructing an explanatory model for "Like"-clicking behaviors of corporate's Facebook community platform users, as well as making significant practical contributions to enhance social and commercial benefits for businesses and individuals.

A GDS (Geomagnetic Depth Sounding) method, one of extremely low-frequency EM methods, has been carried out to examine conductivity anomalies in and around the Korean Peninsula. In this study, new GDS data acquired at the five sites in south-eastern area of the peninsula were incorporated into the previous GDS data. In order to quantitatively interpret observed induction arrows, the 3-D MT modeling considering the surrounding seas of the Korean Peninsula has been performed to evaluate sea effect at each GDS site. The modeling results revealed that the observed real induction arrows were not explained by solely sea effects, consequently two conductive structures that are responsible for the discrepancies between observed and calculated induction arrows were proposed. The first one is the Imjingang Belt, which is thought as an extension of Quiling-Dabie-sulu continental collision belt. The effects of the Imjingang Belt clearly appear at the site YIN and ICHN. The second one is the HCL (Highly Conductive Layer), which is considered as a conductive anomaly by mantle upwelling produced in back-basin region. The effects of the HCL are seen at the site KZU, KMT101, and KMT 107 in the south-eastern region of the Korean Peninsula.
