Wastewater generated through the food waste recycling process have known high concentration, BOD 20,000~150,000 mg/L, which has to treat to the proper level because of a ban on reclamation. But it is impossible to treat less than 10 days by existing water treatment plant. Ecodays Ltd. is to treat this wastewater during 2~4 days by ER-1, which can simultaneously induce the modified PFR(Plug Flow Reactor) of the oxygen transfer rate, MLVSS concentration, and influent concentration to top from bottom of reactor. We tested the pilot test about low concentration food wastewater(BOD 16,500 mg/L) and high concentration food wastewater(64,431 mg/L) at the food waste recycling plant of H-Gun(20t/d). Hydraulic retention time(HRT) of ER-1 for low concentration food wastewater is 2.5day. In low concentration conditions, ER-1 treatment efficiency is to appear BOD 99%, COD 98%, TN 97%, and TP 96%. While ER-1 process for high concentration food wastewater treatment is composed 2 stages, which are to be HRT 2.5day for law wastewater and HRT 1.5 day for secondary treatment. In high concentration conditions, ER-1 treatment efficiency is to appear BOD 97%, COD 84%, TN 66%, and TP 95%. It is treated without temperature control about high temperature($50^{\circ}C$) to appear low treatment efficiency in high concentration conditions.

The Consultative Meeting of the Convention on the Prevention of Marine Pollution by Dumping of Wastes and other matter, 1972 (London Convention 1972) has requested to International Maritime Organization (IMO) Marine Environmental Protection Committee to collaborate and help clarify a boundary issue between International Convention for the Prevention of Pollution from Shops, 1973 as modified by the Protocol of 1978 (MARPOL) and the London Convention concerning 'dumping' versus 'discharges' during normal operations of ships in 2004, and subsequently established a Joint London Convention/MEPC Correspondence Group. The Contracting Parties to London Convention expressed their environmental concerns on the broad interpretation of the "cargo-associated wastes" by the States, which could be discharged by ships under MARPOL. Regulatory regimes for the cargo residues appear to vary among states. Some countries require fur ships to discharge their cargo wastes into the port reception facility and IMO also recommends doing so. This paper examines the related current national and international legal texts for the regulation of disposal of wastes from ships in order to analyze the current global concern on the marine pollution associated with waste discharge during operations of ships. In particular, we attempt to evaluate the likely marine environmental consequences arising from the disposal of cargo residue using an hypothetical case for the coal cargo residue among bulk cargos in this paper, since location, magnitude and frequency of the discharge of coal cargo residues into the sea adjacent to Korean Peninsula are not readily available. The cargo residues may be discharged to the sea according to MARPOL 73/78; however, its marine environmental consequences can be significant depending upon the characteristics and amounts of wastes to be discharged. Also the public tolerance of the environmental consequences would be widely different among nations. Multilateral environmental agreements, in general, more strictly apply their rules if there are other options to disposal at sea, i.e. port reception facility in this case. Therefore, port reception facilities for the wastes generated by ships are recommended to be further constructed in major national ports in order to reduce the risk of environmental damages during the operations of ships.

Faced with the internationalization of capital markets, Korea needs to protect its investors and markets by applying the relevant laws extraterritorially. The Financial Investment Services and Capital Markets Act ("Capital Markets Act") explicitly introduced a new provision recognizing the extraterritoriality of the Act. While Article 2 of the Capital Markets Act comprehensively provides for prescriptive extraterritorial jurisdiction, the enactment of extraterritoriality alone does not guarantee that the Act will apply to cross-border transactions effectively. The effective extraterritorial application of an act is inseparable from the adjudicative and enforcement jurisdiction of the act. Specifically, active investigations and detections by the public regulators might be the first step for enforcing the Capital Markets Act. Unlike domestic regulations, however, multinational enforcement actions outside a regulator's home country becomes more problematic because of various obstacles. This Article examines difficulties which domestic regulators may confront in enforcing the Capital Markets Act extraterritorially and makes several recommendations for more effective multinational enforcement as follows. First, the Korean regulators should continue to foster cooperation through the IOSCO and provide international markets with the information and tools necessary for successful regulation of cross-border transactions. Second, the principle of dual criminality should be applied in a modified form for the effective mutual legal assistance in criminal matters. Third, there should be a legal device for the domestic regulator to freeze foreign wrongdoer's assets located outside Korea to repatriate those assets for distribution to defrauded investors in Korea.

Artificial or natural artifacts, which have historical, artistic, academic or scenic value as national, ethnic or global assets, are designated as "cultural heritages" under the Act on the Protection of Cultural Heritage. Cultural heritages can be divided into tangible cultural heritages, intangible cultural heritages, and monument and folklore heritages. In addition, depending on the object of designation, a cultural heritage can be designated either as a city or a provincial cultural heritage or a cultural heritage material, by a city mayor or provincial governor, and as a state-designated heritage by the administrator of the Cultural heritage Administration. The regular survey is a part of the policy for the preservation and management of state-designated heritages, which requires that surveys be undertaken every three to five years for the preservation, repair and maintenance of cultural heritages. It was stipulated in the Act on the Protection of Cultural Heritage in 2006, and since then has substantially contributed to the preservation and management of state-designated heritages based on the identification of damage to cultural heritages and the application of appropriate treatment measures. However, some parts of the guidelines on the regular survey, legislated in 2006, occasionally give rise to confusion in managing the regular survey system of state-designated movable cultural heritages, and need to be modified to facilitate the systematic management and improvement of the regular survey system. This study attempts to analyze the structure and operation of the regular survey system of state-designated movable cultural heritages, and proposes plans for improving the way of specifying each department which leads, manages and executes the regular survey, the process of entrusting the survey, and its guidelines and forms. I hope that these plans concerning the regular survey of state-designated movable cultural heritages will contribute to improving the quality and management of the system.
