The Convention on International Interests in Mobile Equipment and the Protocol to the Convention on International Interests in Mobile Equipment on Matters specific to Aircraft Equipment were adopted on 16 November 2001 at a diplomatic conference held in Cape Town under the joint auspices of UNIDROIT and ICAO. The entry into force of the Cape Town Convention and Protocol have occurred on 1 March 2006. The Cape Town Convention and Protocol provides an international legal regime for the creation, perfection and priority of security, title retention and leasing interests in aircraft equipment, which will be underpinned by an international registry. The purpose of this paper is to explain the objectives and principles of the Cape Town Convention and Protocol, to review the provisions relating to the international interests in aircraft equipment and international registry for their protection under the Cape Town Convention and Protocol, and to discuss the Issues on Korea's accession to the Cape Town Convention and Protocol. As the anticipated results of this paper, it will contribute to facilitate the financing of the acquisition and use of aircraft equipment of high value or particular economic significance in an efficient manner, and to save very large sums of money annually in financing charges, also the international interests in aircraft equipment will be recognized and protected universally.

A lot of existing wastewater treatment plants (WWTPs) are rebuilt or retrofitted for advanced wastewater treatment processes to cope with reinforced effluent criteria of nitrogen and phosphorous. Moreover, how to treat the wasted sludge from WWTPs has been also issued since the discharge of the wasted sludge into ocean is impossible from 2011 due to the London Convention 97 protocol. These trend changes of WWTPs get a motivation to assess environmental and economic impacts from the construction stage to the waste stage in WWTPs. Therefore, this study focuses on evaluation of environmental and economic impacts of the advanced wastewater treatment processes and waste sludge treatment process by using life cycle assessment. Four advanced wastewater treatment processes of Anaerobic/Anoxic/Oxic ($A_2O$), 5 stages-Bamard Denitrification Phosphate (Bardenpho), Virginia Initiative Plant (VIP), and Modified University of Cape Town (MUCT) are chosen to compare the conventional activated sludge (CAS) and three waste sludge treatment methods of land fill, incineration, and composting are used. To evaluate environmental and economic impacts of each advanced wastewater treatment processes, life cycle assessment (LCA) and life cycle cost (LCC) are conducted based on International organization for standardization (ISO) guidelines. The results clearly represent that the $A_2O$ process with composting shows 52% reduction in the environmental impact than the CAS process with landfill. On the other hand, the MUCT process with composting is able to save 62% of the life cycle cost comparing with the CAS process with landfill. This result suggested the qualitative and quantitative criteria for evaluating eco-environmental and economic technologies of advanced treatment processes and also sludge treatment method, where their main influence factors on environmental and economic impacts are analyzed, respectively. The proposed method could be useful for selecting the most efficient and eco-friendly wastewater treatment process and sludge treatment method when retrofitting the existing WWTPs to advanced treatments.
