This paper investigates the way in which environmental responsibility impacts on corporate financial performance, measured by return on equity (ROE) and return on assets (ROA). Using a sample of Korean firms covering the period 2011-2012, and employing two different test methods, namely the OLS and 2SLS methods, we show that the relationships between environmental responsibility performance and firms' ROE and ROA are positive and statistically significant. However, we show that research and development (R&D) intensity (expenditure) does not affect either environmental responsibility or corporate financial performance. The results of this analysis encourage further empirical analysis of the industries, as well as the use of more than one estimation method to determine environmental responsibility and corporate financial performance within firms.

In order to describe the demographics, etiologic and clinical factors, and outcomes of orbital fractures in children, we have reviewed a case series of 17 patients under 18 years of age with internal orbital fractures (i.e., without involvement of the orbital rim) presenting to the Ghil hospital between March 2000 and June 2001. For 15 of the patients, we performed orbital wall reconstruction with Medpor barrier sheet implantation (thickness 1mm) through transconjunctival approach under endoscopic guidance, while maintaining mere observation on the other 2 patients. There were 14 male and 3 female patients. The most common cause of fractures was accident (7 cases). Inferior wall involvement was most commonly seen, and the trapdoor type fracture was the most common. Thirteen patients had extraocular muscle restriction, 9 had nausea/vomiting and 5 had bradycardia. Diplopia of 9 patients disappeared after 43 +/- 23 days. Nausea/vomiting and bradycardia disappeared rapidly after surgical intervention in all cases. These results suggest that trapdoor fractures with soft tissue entrapment are the most common in pediatric orbital wall fractures, and that most of them are associated with nausea/vomiting. We suggest that early diagnosis, and prompt surgical intervention are required for those patients with oculocardiac reflex.

In recent years, the concept of Regional Innovation Systems (RIS) has evolved into a widely used analytical framework for sustainable economic development. But in reality, the RIS does not seem to be workable due to the lack of governance. To reduce this operational risk, the emphasis on the structure as well as network management of the system should be merged into a more market-oriented as well as performance-oriented governance. In Korea, there are seven RISs among 14 regions nationwide. Empirically, they are not very sustainable. Thus, the article proposes the role of metamediary for the facilitation, network service provision, and collaboration of the system.
