This paper investigates the determinants of total factor productivity(TFP) growth in Korean logistics industry such as market share, ownership structure, age of firm, firm size and debt ratio. Using financial data on individual firms in Korean logistics industry, we first estimate firm-level TFP growth rate and then, regress the estimated TFP growth rate on individual firms market power and structural characteristics. Our empirical results show that logistics firms market share is negatively correlated with their TFP growth rate. Also, we find that older or larger firms are more likely to have higher TFP growth rate.

Ownership of an asset can be identified with the right to exercise "residual control" where the contract is silent about decision rights, or with the right to receive any "residual returns" that remain after contractual. obligations are fulfilled. Although the concept of "ownership" seems reasonably clear in many of the cases, the concepts of residual control and the residual returns that define ownership are actually quite elusive. For large corporations, there is really no single individual who owns both the residual returns and the residual control. Despite the limited qualifications, ownership is clearly. the most common and effective meas to motivate people to create, maintain, and improve the value of assets. In this paper, we try to clarify the relationships among financial structure, ownership, and corporate control with the concept of ownership defined as the residual control and the residual returns, Financial securities are not just claims to part of a firm's net income. They give the security holder certain rights. A careful matching of rights of control and returns can create incentives that increase total value of the firms. In the corporate firms, managers, lenders, and shareholders have different interests. And the financial structure affects how different those interests are and what decisions management will make. Managers are, in general, better informed than investors about the firm's prospects. The financial decisions by managers may affect investors' beliefs and, therefore, the price of shares and the value of the firm.

Few prior studies investigated the correlation between corporate ownership structure and environmental information disclosure. Using environmental index disclosure in GRI (Global Reporting Initiative) reports of the Korean companies, the study examines the effects of ownership structure on the magnitude of environmental information disclosure. A total of 220 firm-years during 2013-2016 period are analyzed. The empirical results of the study indicate that the institutional and foreign investors' ownership have positive correlations with environmental information disclosure, while the executives' within board of directors has a negative correlation. The ownership by largest shareholders including those with special interests shows no significant relationship with the environmental information disclosure.

We investigate the relationship between ownership structure and firm performance. For this paper, we use the 'donation' figure from the income statement of each firm as a measure of firm Performance lather than short-term financial measure that has been wifely used by previous studies. Our results are consistent with the idea that family ownership is both prevalent and substantial in Korea. More importantly, however, non-family firms are found to give more donations than family firms. This suggests that non-family firms more readily recognize the significance of corporate social responsibility and play an active role in philanthropy.

I investigate whether the efficient ratios used as the proxies of the agency costs maintained by Ang et al.(2000) is significant. Utilizing a sample of 77 manufacturing companies listed on the KOSDAQ from the TS2000 of the KSDA, The results are as follows. Agency costs are found to be decreasing with the ownership share of controlling shareholders and accounting performance becomes higher. But firm value measured by Tobin's Q ratio becomes lower according as the ownership of the controlling shareholders increases. If agency costs decrease in proportion to controlling shareholder's share, firm value should be higher according to the agency theory by Jensen and Meckling(I976). But the results of the empirical test of this study are inconsistent with Jensen and Meckling's(1976). Therefore the following study on the more useful proxies stand for agency costs should be needed.

The oleophobic property of surfaces modified with micro-post structures are investigated for a range of micro-post diameter ($11-23{\mu}m$) and pitch ($20-40{\mu}m$). The contact angle of an oil droplet on surfaces with various micro-post dimensions was calculated using the Cassie-Baxter model and did not show a good agreement with the measured contact angle. From measurement, the micro-post with diameter of $23{\mu}m$ and pitch of $32{\mu}m$ was found to have the highest contact angle ($134.3^{\circ}$).

This paper empirically examines whether ownership disperses when a venture firm its IPO (initial public offerings). The data for this study were collected from 91 firms that were initially listed on KOSDAQ between January 1, 2004 and December 31, 2007. We explored the influence of the underpricing of IPO on the change of large shareholders. The first finding of this investigation is that the number of shareholders of the venture firms who underpriced IPOs still increased after the closing of lockup. This is consistent with the findings of Booth and Chua(1996) and Brennan and Franks(1997). Second, the share of the large stockholders of the venture firms that a venture capital company invested decreased significantly after the end of lockup. Third, the venture businesses with higher ratio of flotation showed a significant decreasing of shareholders after the closing of lockup.

In this study, we examined the effects of major shareholder's holdings and foreign shareholder's holdings on capital structure with the samples of listed non-financial firms in KOSPI and KOSDAQ. More specifically, we conduct the data on 7,074 large firms and 2,394 SMEs(Small-Medium Enterprises) before and after the adoption of K-IFRS from 2002 to 2019. The main results can be summarized as follows. The results indicate that the adoption of K-IFRS affects the capital structure of large firms more than SMEs. The major shareholder's holdings and the foreign shareholder's holdings of the large and SMEs listed on the KOSPI and the KOSDAQ market have a significant effect on the leverage ratio. It can be seen that major shareholders of large firms and SMEs reduce the leverage ratio by recognizing the use of debt as financial risk. In addition, it can be seen that regardless of whether or not K-IFRS is adopted, foreign shareholders recognize the use of debt as financial risk and reduce the leverage ratio in order to reduce the investment risk.

새만금 유역의 하류 평야지대는 농업 관개 및 배수가 제수문의 영향을 받고 있으며, 상류 축산밀집시설에 따라 농업 비점오염원 유입이 수계 환경오염에 미치는 영향을 평가하는 것이 필요하다. 본 연구에서는 새만금 유역의 하류 제수문을 대상으로 유역 모형과 전산유체역학 모형을 이용하여 유입, 유출 그리고 오염원 등의 영향을 분석하고자 한다. SWAT (Soil and water assessment tool)은 유역 모형으로 수문순환 및 비점오염원을 모의하기 위해 개발한 모형이다. CFD(Computational fluid dynamics)는 구조물을 설계하고 유체, 기체 등의 역학을 모의할 수 있다. SWAT 모형을 이용하여 농촌 소유역을 대상으로 하류 제수문 위치를 출구로 지정하여 수문을 모의하고 그 결과자료는 CFD에 입력할 수 있다. CFD는 하류 제수문 구조물을 설계하고 SWAT 모형의 수문자료를 입력하여 제수문의 유입 및 유출 영향을 평가할 수 있다. SWAT 모형 구축을 위해 2015-2018년까지 기상, 수위, 유량 관측자료를 수집하였으며, 보정기간과 검증기간은 각 2년이며, 모형 성능 검증에 사용한 적합성 평가 지수는 R² (Determine coefficient), RMSE (Root mean square error), 그리고 NSE (Nash-sutcliffe efficiency coefficient)를 사용하였다. 모형의 보정은 SWAT-CUP 자동보정프로그램을 사용하였으며, 모형의 보정지수는 NSE를 사용하였고, 1,000회 반복 수행을 통해 매개변수를 최적화하였다. CFD 모형은 제수문의 실제 규격을 바탕으로 동일한 구조를 고려하였으며, 수문조작을 고려하여 유입 및 유출을 모의하였다. 본 연구는 유역차원과 구조물 차원의 모델링을 연계하는 것으로 최근 기후변화에 따라 급격히 변화하는 유역환경에 대처할 수 있는 방안이 될 수 있을 것이며, 제수문 시설을 관리하는 기관에서도 합리적인 운영방안에 대한 기초자료로 기여할 수 있을 것으로 사료된다.

우리나라는 1997년 IMF 경제위기 이후 기업의 지배구조와 관련한 상법과 증권거래법 등이 수차례에 걸쳐 개정을 통한 정비가 되었다. 기업지배구조에 대한 문제는 우리나라 경우에만 한정되는 것이 아니라 미국을 비롯한 유럽 등 많은 선진국에서 중요한 문제점으로 대두되고 있는 것이 사실이다. 특히 우리나라에서 기업지배구조와 관련하여 많은 문제가 발생되고 있는 것은 지배주주와 경영진의 기업경영에 대한 감독 등이 제대로 이루어지지 않았을 뿐만 아니라 지배주주와 기업 경영진들에게 그에 책임을 제대로 묻지 않았기 때문이다. 그리고 아직도 우리나라 대부분의 기업들에 있어서 오너 경영자의 소유주식 비중이 높은 관계로 의사결정권을 독선적으로 행사하는 등 사실상 경영의 건전성을 확보할 수 없었던 것이다. 따라서 본 연구에서는 이사회가 본연의 기능을 회복하고 바람직한 지배구조를 개선하는데 있어서 걸림돌이 되는 부분을 검토하고 그에 대한 효율적인 개선안을 제시하고자 함이 연구의 목적이다.
