This study empirically examines the correlation between the quality of e-government and trust in government. It used survey data collected in 2013 from the metropolitan areas of Seoul. An index was developed to measure the quality of e-government services, and the Gov 3.0 values were reflected in the analysis, including openness, sharing, communication, and collaboration. The results show a partial correlation between the quality of e-government service and trust in government. In addition, the level of trust varied according to the different type of the digital divide groups. It suggests that as ICT (Information Communication Technology) has become more sophisticated, a willingness to share information among organizations and stakeholders may become a major factor to thoseactively seeking information and resources to make value-added products. It also suggests that more integrated data management including network securityand an open attitude toward information sharing will be more important beyond the level of technical issues.

This communication reports on the b-diketiminatophosphane palladium-catalyzed copperfree Sonogashira coupling of aryl chlorides with alkynes. A catalyst loading of 0.5 mol% is sufficient to achieve high performance under relatively mild reaction conditions. Furthermore, dialkynylbenzenes are efficiently prepared by one-pot double Sonogashira couplings of aryl dichlorides.

A zeolitic 4A type material was successfully prepared from natural basalt rock by applying an alkali fusion process and hydrothermal synthesis. In particular, the optimum synthetic conditions were examined at different crystallization times. Several methods such as XRD, SEM, EDX, and N 2 and CO 2 adsorption analysis were used to characterize the synthesized 4A type zeolite. In addition, CO 2 adsorption equilibrium capacities for this basalt base zeolite were measured over temperature ranges from 283 to 303 K and pressure ranges from 0.1 to 1500 kPa in a volumetric adsorption apparatus. Then the results were compared to those of commercial zeolite. Moreover, to further investigate the surface energetic heterogeneity of the prepared zeolite, the isosteric heat of adsorption and adsorption energy distribution was determined. We found that basalt based zeolite 4A shows a CO 2 adsorption equilibrium capacity of 5.9 mmol g À1 (at 293 K and 1500 kPa) which is much higher than the 3.6 mmol g À1 of the commercial zeolite as its micro-pore surface area, micro-pore volume and surface heterogeneity indicate.
