The Korean Veterans' Pension Fund has previously pre-purchased Gibril Tower on Business Complex in Dubai, UAE, via a project-financed construction investment. Although the property is near completion, the investor syndicate's attempt to debt-finance due arrears was foiled in Dubai central bank's credit control of real estaterelated loans. Accordingly, the investment coordinator offered an additional capital injection, a collateralized leverage, and a maturity extension to the syndicate. If the syndicate rejects the offer, they may risk a nearcomplete capital loss and a possible default of the main contractor. Otherwise, the syndicate may still face uncertainties regarding interest receivables, principal re-payment, foreclosure, economic recession in Dubai, and the Islamic bond bill in the Korean Parliament. A possible exercise of the latter option may be due to the agency-prone nature of pension fund managers. Given these qualitative risk factors as at April 1, 2011, a real options approach-implied optimal decision suggests an extended and complete cash augmentation into the project finance deal.

스타는 우리들의 삶과 무척이나 밀착해 있다. 이들이 만든 소비문화가 수용자대중의 의식에서부터 행동에 이르기까지 커다란 영향을 미치는 것만 보아도 그렇다. 스타의 경제적인 역할도 크다. 이들은 소비문화를 확산함으로써 기업들의 상품판매를 촉진하고, 이윤 실현을 돕는다. 더구나 스타는 사람들의 일상에 깊숙이 침투해 있다. 이렇게 스타들이 인기를 바탕으로 사람들의 일상적인 담론을 지배하는데 이런 힘을 두고 스타권력이라 한다. 이에 필자는 스타권력이 어떻게 형성되고, 어떻게 자본 축적에 기여하는지 조사했다. 이 연구는 3가지 연구 문제를 설정하여 스타권력의 자본주의적 성격을 규명하고자 했다. 이 글은 정치경제학을 분석의 틀로써 이용했다. 스타의 정치경제학이란 스타가 자본 증식에 기여하는 한편 지배이념을 확산하는 기능을 행태를 비판하는 학설이다. 논의 결과 스타권력은 경쟁을 통해 인기를 얻고 이에 기초하여 시장에 영향을 준다. 그럼으로써 스타권력은 수용자대중의 일상적 담론을 지배하는 힘을 가진다. 이것이 스타권력의 원천이다.

As implied by the terms of IT productivity Paradox, measuring the Information technology contribution to economic performance has been one of the challenging issues to both policy makers and business professionals. As such, diverse attempts with sophisticate analyses have been reported in the literature to analyze the effect of IT contributions. In this paper, we follow Growth Accounting Method to measure the IT contribution effect to manufacturing firm's economic performance in Korea. Various regression methods and statistical analyses are applied with fourteen years of industry Panel data. Using the Cobb-Douglas function, time lag analysis is made to understand IT effect to economic growth. Instead of capturing data from individual firm, industry level data from the National Statistics Bureau is used for IT capital, non-IT capital, and so on. Statistical analysis following the panel unit test and Panel co-integration test was performed to reveal the exact effect of IT contribution to economic performance. Empirical testing results for non-stationary nature of IT investment effect are reported as well as IT contribution to manufacturing industry's economic performance.

This study is an attempt to explore the nature and characteristics of strategic impact of green strategy by environmental capital, corporate reputation, and technology strengths on the firm's performance across countries. The main question addressed in this paper relates to how corporate sustainability, corporate reputation, technology strength, and capabilities influence the firm's economic performance with respect to diverse dimensions of performance measures including sustained growth through the leading firms across countries in the United States, Canada, Europe, and Asia-Pacific countries. Particularly, this study attempts to empirically explore the directions and magnitudes of the operational links between new emerging strategic core competencies (e.g., sustainability green strategy by environmental focus for more sustainable path, corporate reputation by corporate social responsibility and image enhancement, and technology strengths to develop a new product and market) and the firm's economic performance with respect to diverse dimensions of performance such as accounting (ROE and EOA) - and market-based performance (Market value and Tobin's q). Considering all possible limitations that might exist with regard to selected samples and methods, this study demonstrates that environmental sustainability, corporate reputation, technological capabilities and competencies through R&D intensity and patent are most likely to be significantly associated with most market-based performance measures, but the strategic significance of other variables such as capital intensity, leverage, and administrative cost efficiency on performance tends to be different depending on which performance measure is used across different countries with diverse economic and business contexts.

Young Tolstoy, when he was an already well-known writer, accomplished his first overseas travel in 1857, which gave him imaginable opportunities to compare his country's social strata with others such as serfdom, monarchical Russia and industrial and capital Europe. The present story is, indeed, the work which is influenced by those experiences by young Tolstoy during his first journey into Europe. Written in the form of booklet-like-small-piece, rather than an artistic work, the text presents the writer's severe criticism on the world of nature and civilization. Close to the nature itself, narod are those common people for Tolstoy, and they represent love, while the nature creates a necessity to love, hope and bottomless happiness of life. On the contrary, the civilized or civilization itself is considered artificial, willy, reasonal, and erotic congruity among people. For the writer, the most unsafe and ugly, seamy side of the westernized society is a lack of necessity to unify people to people. Though in its early embryonic stage, young Tolstoy's worldview is reflected in this work, especially his sharp tongue on the western people and their society is also detected when the write imposes his message under the mask of a gypsy singer. In addition, the narrator who seems an obvious Tolstoy's mouthpiece delivers his own ideas and impression on the western world, history, art, and literature. For this very reason, the present work contains numerous signs from which the reader is able to interpret, understand, and figure out what young Tolstoy imposes for his work.

A challenge in fostering virtual communities is the continuous supply of knowledge, namely members' willingness to contribute knowledge to their communities. Previous research argues that giving away knowledge eventually causes the possessors of that knowledge to lose their unique value to others, benefiting all except the contributor. Furthermore, communication within virtual communities involves a large number of participants with different social backgrounds and perspectives. The establishment of mutual understanding to comprehend conversations and foster knowledge contribution in virtual communities is inevitably more difficult than face-to-face communication in a small group. In spite of these arguments, evidence suggests that individuals in virtual communities do engage in social behaviors such as knowledge contribution. It is important to understand why individuals provide their valuable knowledge to other community members without a guarantee of returns. In virtual communities, knowledge is inherently rooted in individual members' experiences and expertise. This personal nature of knowledge requires social interactions between virtual community members for knowledge transfer. This study employs the social capital theory in order to account for interpersonal relationship factors and identity theory for individual and group factors that may affect knowledge contribution. First, social capital is the relationship capital which is embedded within the relationships among the participants in a network and available for use when it is needed. Social capital is a productive resource, facilitating individuals' actions for attainment. Nahapiet and Ghoshal (1997) identify three dimensions of social capital and explain theoretically how these dimensions affect the exchange of knowledge. Thus, social capital would be relevant to knowledge contribution in virtual communities. Second, existing research has addressed the importance of identity in facilitating knowledge contribution in a virtual context. Identity in virtual communities has been described as playing a vital role in the establishment of personal reputations and in the recognition of others. For instance, reputation systems that rate participants in terms of the quality of their contributions provide a readily available inventory of experts to knowledge seekers. Despite the growing interest in identities, however, there is little empirical research about how identities in the communities influence knowledge contribution. Therefore, the goal of this study is to better understand knowledge contribution by examining the roles of social capital and identity in virtual communities. Based on a theoretical framework of social capital and identity theory, we develop and test a theoretical model and evaluate our hypotheses. Specifically, we propose three variables such as cohesiveness, reciprocity, and commitment, referring to the social capital theory, as antecedents of knowledge contribution in virtual communities. We further posit that members with a strong identity (self-presentation and group identification) contribute more knowledge to virtual communities. We conducted a field study in order to validate our research model. We collected data from 192 members of virtual communities and used the PLS method to analyse the data. The tests of the measurement model confirm that our data set has appropriate discriminant and convergent validity. The results of testing the structural model show that cohesion, reciprocity, and self-presentation significantly influence knowledge contribution, while commitment and group identification do not significantly influence knowledge contribution. Our findings on cohesion and reciprocity are consistent with the previous literature. Contrary to our expectations, commitment did not significantly affect knowledge contribution in virtual communities. This result may be due to the fact that knowledge contribution was voluntary in the virtual communities in our sample. Another plausible explanation for this result may be the self-selection bias for the survey respondents, who are more likely to contribute their knowledge to virtual communities. The relationship between self-presentation and knowledge contribution was found to be significant in virtual communities, supporting the results of prior literature. Group identification did not significantly affect knowledge contribution in this study, inconsistent with the wealth of research that identifies group identification as an important factor for knowledge sharing. This conflicting result calls for future research that examines the role of group identification in knowledge contribution in virtual communities. This study makes a contribution to theory development in the area of knowledge management in general and virtual communities in particular. For practice, the results of this study identify the circumstances under which individual factors would be effective for motivating knowledge contribution to virtual communities.

Petroleum is the most consumed energy source in Korea with a usage rate of 38.7% among the available primary energy sources. The price of liquid petroleum products in Korea includes taxes such as transportation·environment·energy tax. Thus, illegal production and distribution of liquid petroleum is widespread because of its huge price difference from that of the normal product and its tax-free nature. Generally, the illegal petroleum product is produced by mixing liquid petroleum with other similar petroleum alternatives. The two kinds of gasoline, common gasoline and premium gasoline, are being distributed in Korea. The premium gasoline is often adulterated with cheaper common gasoline that lowers the octane number of gasoline. It is possible to distinguish them with their color difference, green and yellow for different grade gasoline. However, when small volume of common gasoline is added to premium gasoline, it is difficult to determine whether premium gasoline contained common grade or not. In this study, we inspect gasoline, which is illegally produced by mixing common gasoline to premium gasoline. When the ratio of mixing common gasoline is increased, premium gasoline shows decreasing absorbance at 600 nm and 650 nm under UV-Vis spectrometer. Moreover, the detected intensity (mV·s) of green dye in high performance liquid chromatography (HPLC) was decreased by common gasoline under 0.99 correlation value. The more the common gasoline is mixed, the more olefin and naphthene are detected by gas chromatography. In addition, trimethyl pentane as octane improver, paraffin and toluene are decreased by common gasoline mixing. The findings of this study suggests that illegal petroleum can be identified by analysis of components and simulated samples.
