Despite the fact that corporate real estate ratio accounts for a considerable proportion of the assets, such researches and studies are lacking and there is not enough such policies to utilize real estate more effectively in Korea. In particular, after IFRS adoption, the owner and manager needs to utilize corporate real estate assets as the assets are revalued. In this study, we analyzed the relationship between corporate governance, corporate real estate holding policies and firm value based on financial data from 2010 to 2016. As a result of regression analysis, this study showed that more Dictatorship Portfolio, the higher proportion of corporate real estate holdings. Next, the higher proportion of corporate real estate holdings, the lower the firm value. This study suggests that corporate real estate is recognized an important factor and should have proper holding ratio. I will continue my research to show that the corporate holding policies are an important asset impact by verifying the mediating effect between corporate governance and firm value in the future.

Purpose - The objectives of this study are as follows. First, it aims to suggest an analysis model that has integrated the relationship between the two factors and export performance and conduct an empirical analysis of the factors. Second, the study seeks to analyze the mediating effect by setting direct channel governance as a specific activity to connect market orientation, a cultural asset, to export performance. Third, through these analyses, the study intends to apply the relationship between market orientation and direct channel governance that the existing studies have failed to observe comprehensively on SMEs in Korea. Based on these analyses, the study expects to expand the discussion of previous researches by analyzing the mediating effect of direct channel governance. Research design, data, and methodology - This study developed a model that has integrated market orientation, direct channel governance, and export performance. It established 7 hypotheses including the mediating effect of direct channel governance. Market orientation was consisted of customer orientation and competitor orientation, and 4 latent variables were measured by 18 questions. LISREL, an analysis tool of structural equation model, was used for hypothesis test and there were 183 sample for analysis. Results - The analysis results showed that customer orientation has a positive influence on direct channel governance, but competitor orientation did not have a statistically significant effect. On the contrary, export performance showed an opposite result. That is, customer orientation did not have any influence but competitor orientation had a significant influence on export performance. It was also confirmed that there was a significant influence in the relationship between channel governance and export performance. According to the analysis of mediating effect, direct channel governance had a full mediating effect between customer orientation and export performance. Conclusions - The study results demonstrated that it is important to build a direct channel governance on the export SMEs in Korea, especially since the direct channel governance complements the influence of customer orientation that does not directly influence export performance among market orientation activities. This implies that Korean export SMEs must strive to build an effective direct channel governance.

This paper aims to determine whether the changes in management performance of domestic agricultural cooperatives had an effect on the election results of Korean Agricultural Cooperatives in 2015. Financial performance data (2012-2015) prior to the Nation-wide Cooperatives elections in 2015 were reviewed to determine the impact of the election outcome on the election results. 2SLS Probit regression analysis shows that the significant parameters for incumbent president turnover in the 2015 election were the candidates' age, net profit decrease in 2014, and ROA comparison to similar asset-size group. These results support the conclusion that the union members of KAC consider whether the age of president is over 60, whether the net profits of the cooperatives are worse than the previous year, and compare the results of similar groups' managerial performance (ROA).

The paper examines the ownership structure and the firm value of online firms in the world. Data are gathered by using FACTIVA database for firms in the Dow Jones index for the 2014 fiscal year. The Ordinary Least Squares regressions, the Generalized Linear Model, and the model selection criteria are employed to analyze the relationship between the dependent and the independent variables. The paper tests theories such as the convergence of interest theory, the managerial entrenchment theory, and the eclectic theory. The paper finds that the ownership structure has an influence on the firm value depending on the rank of the large shareholders. While the first large shareholders have a negative association with the firm value, the presence of the second and the third large shareholders have a positive influence on the firm value. The paper also finds that the identity of the largest shareholders whether they are insiders or outsiders have an influence on the firm value. The proportion of shareholding by a large shareholder and her identity are variables which predict a firm value.

This study examined how the households used and combined financing sources to pay for college education. It compared the probability of using each source (current incomes, saving, education loans and grants) by households' socio-economic characteristics and analyzed which factors influence the decision to use each source and the amounts from each source for financing college education. Data for this study were from a questionnaire completed by 4-year college students (n=623) and were analyzed by t-tests, ANOVA and Heckman's two-step estimation models. The findings of this study were as follows: First, the most frequent source for college education was parents' savings and the second one was parents' incomes. Also, the most frequent combination of sources was saving and current incomes and the second was combination of three sources, saving, incomes and education loans. Second, the probability of using incomes was higher for younger students than for older students. The number of siblings showed significant differences among income, savings and education loans. Those who had higher incomes were more likely to use current incomes, saving, but less likely to borrow for financing college education. Middle-class income groups were more likely to borrow for education. Third, household incomes and asset holdings had generally positive impacts on the probability of using incomes and savings for college education, while total debt burden decreased both the probability and amounts of income and saving sources. The college costs had significantly positive effects on both the probability and the amounts of all of financing sources. Total grants received significantly decreased the amounts from incomes, savings and borrowing sources.

Purpose: In this paper, we investigate whether the endeavors for 6 sigma quality management by a firm have positive effects on its financial performance and the length of 6 sigma implemented period affects its financial status. Methods: We conduct the analysis using the data from Workplace Panel Survey 2009. We use multiple linear regression in order to analyze the relationship between the efforts for quality management and financial performance. Specifically, the return on assets (ROA) and return on equity (ROE) are investigated as dependent variables and the efforts for quality management as independent variable. The Box-Cox transformation and Cook's distance are also used. Results: As a result of the analysis, the indication is that companies that put effect into the six sigma quality management have a positive result in its financial status. In detail, the efforts for six sigma quality management have positive effects on total asset turnover ratio and six sigma implemented period on net income to net sales ratio. Additionally, companies with longer(shorter) period of six sigma program have more (less) improvement in its financial status. Conclusion: It can be concluded that the company's efforts for quality management positively influence financial performance.

The purpose of this study is to investigate the factors that affect professor startups and their performances in Universities in Korea. We included 5 categories of factors: University's size and reputation, University's technology commercialization staff number and startup deregulation, University's resources for research and technology commercialization, University's patents and professors' publication, and student startups. We analyzed 150 Universities, using Korean government's Academyinfo database, and additional data for University ranking and government's projects for University startups. Our analysis shows that Universities' fund amount for research and technology commercialization, Universities' amount of patents give a positive impact on Universities statistically significantly, while Universities' size or reputation does not. In addition, the amount of patents and startup projects funded by the government give a significantly positive impact on the annual sales of the professor startups. Furthermore, student startups are in a positive relationship with professor startups and their sales, showing a synergy effect between the two startup groups in Universities. The result implies that Universities and government need to focus on supporting patenting activities, providing technology commercialization funds, and collaboration activities between professors and students for their startup activities.
