In this paper, the author focused on the establishment of structural equation model for cyber copyright ethics based upon literature reviews. And to draw a factors influencing cyber copyright ethics reception, author are applied a human-technology-contents-culture (HTCoC) perspectives. The basic idea is that copyright ethics is one of the most significant solutions to protect copyrighted materials. Among solutions like technology, institution and legal framework, ethics may be the most powerful alternatives to face with copyright infringement. Among variables, copyright culture is appeared that can mediate the other factors in cyberspace. Concluding remarks is that more sound and sustainable cyber copyright ethics is needed to cope with unexpected negative use of information technology in digital convergence era.

In order to improve our knowledge of the characteristics of organic compounds in coastal waters, water samples were collected from the Incheon coastal region, the Hyungsan River in Youngil Bay and the Busan coastal region. Also, mooring was carried out near the Kanghwa Island and Seo Island. In this study, the relationship between the total organic carbon (TOC) and salinity, chemical oxygen demand (COD) and salinity were evaluated and determined. Riverine end-member of TOC into the Korean coastal area and its COD estimated from these relationships were 5.32 mg C/l and 8.87 mg O$_2$/l, respectively. The oxidation efficiency of COD to TOC estimated using the high-temperature catalytic oxidation method was about 47％. The linear relationship between TOC and COD was derived as COD (mg O$_2$/l)=0.61${\times}$TOC (mg C/l) -0.03, (R$^2$=0.66). Therefore, it is possible to estimate total organic carbon using this equation from previously reported chemical oxygen demand.
