  • EIA has been introduced as a tool for environment protection into promulgation of the Environment Preservation Act in 1977, which replaced the Pollution Control Act in Korea. EIA system has been improved with the enlargement of project type, public participation, guideline improvement, and regulatory development. Recently, Environmental Impact Assessment(EIA) Act will have an important role for sustainable development. This article deals with regulatory development, implementation order, EIA project type, and EIS preparation guidelines by Act promulgated and amended, also it explains comparison analysis of Environmental Policy Act and Environment Impact Assessment Act Major results are summarized in the table.

  • In this research, a drop impact analysis of a fuel assembly in a research reactor is carried out to determine whether the fuel plate integrity is maintained in a drop accident. A fuel assembly drop accident is classified based on where the accident occurs, i.e., inside or outside the reactor, since each occasion results in a different impact load on the fuel assembly. An analysis procedure suitable for each drop situation is systematically established. For an accident occurring outside the reactor, the direct impact of a fuel assembly on the pool bottom is analyzed using implicit and explicit approaches. The effects of the key parameters, such as the impact velocity and structural damping ratios, are also studied. For an accident occurring inside the reactor, the falling fuel assembly may first hit the fixing bar at the upper part of the standing fuel assembly. To confirm the fuel plate integrity, a fracture of the fixing bar should be investigated, since the fixing bar plays a role in protecting the fuel plate from the external impact force. Through such an analysis, the suitability of an impact analysis procedure associated with the drop situation in the research reactor is shown.

  • The aim of this study is to suggest the introduction of family impact analysis. Family impact analysis is needed to evaluate family policies from the family perspective. This study deals with the definition of family impact analysis and the cases of other impact analysis, such as gender impact assessment and employment impact analysis. In addition, this study suggests the introduction of family impact analysis with evaluation methods, evaluation indicators, and evaluation processes. Evaluation methods are divided into self-assessment and specific-assessment. Evaluation indicators need to be developed based on the family strength. This research also suggests the securing of family time as a basic assessment indicator. The evaluation processes consist of object selection, assessment, evaluation report, and policy improvement. Finally, this study suggests that family impact analysis is a strong strategy for promoting family-friendly policies. In order to introduce family impact analysis in a more systematic manner, further studies on the standards of assessment, formation of research institutions, and the legislative system will be necessary.

  • Purpose - This study addresses an acquisition's impact on a firm's strategic relationship based on findings of existing academic studies and theoretical assertions. Through examining existing research results and theoretical grounds for an acquisition's impact on various stakeholders, this study indirectly approaches the impact on stakeholders including alliance partners. Research design, data, and methodology - This research identified a variety of related theoretical foundations and empirical studies. Research objectives of prior studies mainly focused on merging firms and direct participants of acquisition activity. In addition, academic attention on the impact on rival firms has recently been growing. However, little research on alliance partners was found. Prior studies simultaneously employed event study methodology and cross-sectional analysis to make further theoretical contributions. Results and Conclusions - Based on the findings of prior studies, this research proposed a complementary research model for future academic inquiry into the impact of an acquisition on an alliance partner's return and for predicting an acquisition announcement's effect on alliance partners.

  • The nonlinear dynamic analyses were performed by newly developing an appropriate impact modelling for the evaluation of the CANFLEX fuel bundle structural integrity during the refuelling period. The initial load under the refuelling condition is considered as initial velocity at impact incident, and the impact of one bundle contacted another bundle for at short time is studied by performing several dynamic analysis method. The impact analysis shows to predict an appropriate velocity and acceleration profile according to load time history for two bundles impact.

  • Public participation in the Environmental Impact Assessment(EIA) has been implemented since the August 1 of 1991 with the Environmental Policy Act promulgation in the August 1 of 1991. It is structured to comment on draft Environmental Impact Statement(EIS) through open reviewing, public meeting and hearing. Though public participation has an important role in determining environmental significance, it is room for improvement. With positive public participation and system development such as Environmental Impact Assessment Act on June 11 of 1993, the effectiveness of it will be improved. This article is composed of status of public participation, comparison with other countries, comparison analysis by items of EIS prepared before and after public participation, and contents of public opinions in EIS.

  • The energy-absorbing characteristic of impact limiters affects the cask design so significantly that it should be evaluated as accurate as possible. The objective of this study is to find the influence of the impact limiter's steel case and gusset plates which enclose the shock absorbing cellular material on the impact energy absorption. The influence of impact limiter's steel case and gusset plate stiffeners on the impact energy absorption behavior under horizontal drop impact was evaluated for a radioactive isotope transport cask. Though the impact limiters mitigate the impact damage of the cask, the impact limiter's steel case and gusset plate stiffeners increase the impact force so significantly that should be designed as soft as possible. The impact analysis without considering impact limiter's steel case and gusset plates stiffener gives non-conservative results, so the stiffness of the steel case and gusset plates should be considered in impact analysis.

  • Remote sensing begins to be applied in Environmental Impact Assessment(EIA), and it can systematically assess land use which is an important factor in EIA. This study is to predict land use change of Ulsan region and to assess impact on land use using the past and the present data of remote sensing. Also we analyzed an impact area influenced by EIA projects through the integration of remote sensing and GIS. This technique will be applied to the screening stage in EIA.
