This paper focused on meaning, problems and prospect of structural reform of coastal and offshore fisheries in Korea. Structural reform can be defined as effective combination of production factors in order to enhance fisheries productivity and it can be realized mainly through fleet reduction, modernization of fishing vessels and fishing gear etc. However, the structural reform alone will not be sufficient to advance Koreanl fisheries facing with severe challenges from both inside and outside. Domestically, worsening status of fisheries resources, decreasing number of fishermen, worsening financial status of fisheries businesses and severe competition cause structural problem in fisheries sector and internationally the pressure from WTO and OECD to reduce tariff and subsides in fisheries poses severe challenges. The structural reform should be carried out in relation with the general adjustment programs across coastal and offshore fisheries such as M&A among fisheries businesses, adjustment of number of fishing permits and fishing areas. And the policy to enhance the fishing productivity is needed for recovery of fisheries resources and for the reduction of fishing efforts, that is, the approach which combines economic and resources concerns is needed. For the effective implementation of the reform, effect analysis of the reform program is needed and at the same time, eradication of illegal fishing, reduction of fishing fleet and reduction of fishing cost should be realized. However, the most important thing is the will and efforts of the government for successful reform. If the government does not exert sufficient efforts for the structural reform, Korea could be degraded into a backward country in fisheries.

Fueled by ballooning oil prices, waste plastics are now regarded as being cheap and abundant renewable sources, removing their stigma of dirty wastes Catalytic pryolysis of plastics in liquid phase allows recovery of light fuel oil as well as green treatment of polymerics wastes, and therefore significant efforts have been devoted to this research field. In this study, catalytic Pyrolysis of LDPE was carl ied out in semi-batch reactor which equipped a unit of separation and recirculation. The effect of react ion conditions were examined by analyzing liquid oil yield and carbon number distribution of products

In recent, there are tremendous efforts to apply co-generation concept in automobile to improve its thermal efficiency. The co-generation is basically a simple Rankine Cycle that uses the waste heat from the engine exhaust and coolant for heat source. In spite of developed nano technology and advance material science, the bulky co-generation system is still a big concern in automotive application. Therefore, the system should be effectively designed not to add much weight on the vehicle, but the capacity of the waste heat recovery should be still large. With such a goal in mind, the system thermal efficiency was investigated in terms of the system operation condition and working fluid. This paper provides a direction for the optimal design of the automotive co-generation system.

The management of municipal solid waste (MSW) is essential for every community; and, it is currently a major challenge in Nigeria. This paper provides an overview of the current MSW management trends in Nigeria and proposes new sustainable MSW management systems. Across Nigerian cities, MSW management is characterized by inefficient collection and transportation to disposal sites. Collection services do not reach some unplanned areas and slums due to poor street network. Even some planned areas are not reached by collection services. The informal sector contributes to waste collection, resource recovery and recycling; however, their activities are not recognized by the governments. Markets exist for recovered materials but more efforts need to be geared towards intensive recovery of materials and expansion of these markets. Despite the high proportion of putrescible matter in MSW, the only form of treatment commonly used currently is open burning for volume reduction. The high organic fraction presents a great opportunity for composting and anaerobic digestion. Ultimate disposal is currently done in open dumpsites. This needs to be upgraded to engineered landfills that are properly sited and adequately operated by well trained personnel. There is an emerging waste stream of concern, electronic-waste (e-waste), that requires urgent sustainable management as e-waste are currently co-disposed with other waste streams or burnt in the open posing detrimental health impacts.

미국에서는 재난으로 인한 기반시설물의 피해를 줄이기 위해 국가기반시설 리질리언스 확보가 국가기반시설보호계획에 활용되고 있다. 여기서 "리질리언스"는 재난으로 인한 시스템의 영향을 효율적으로 줄일 수 있는 기반시설 시스템의 능력으로, 리질리언스 비용으로 정량화가 시도되었다. 리질리언스 비용은 시스템 영향과 복구노력을 합한 것으로, 리질리언스 평가 사례는 리질리언스 평가시 복구노력을 고려할 필요가 있음을 보여주고 있다. 본 논문은 리질리언스 비용을 설명하고, 연구 사례를 통해 리질리언스 비용의 평가 방법을 보여주고자 한다.

As a part of efforts to establish the positive list system (PLS) in South Korea, a method to determine residual emamectin benzoate (EB) in various aquatic products using QuEChERS-EDTA and LC-MRM was developed. The developed method was validated in the aspects of specificity, linearity (correlation coefficient of at least 0.996), sensitivity (the limit of detection and the lower limit of quantitation ${\leq}5ng/g$), recovery (the recovery range of 87.4 and 96.2), and precision (the relative standard deviation of recovery between 0.9 and 13.5). Additionally, the validated method was successfully applied for monitoring EB contamination in eel, halibut, and shrimp collected from local food markets. To our knowledge, the present method is the first one to determine residual EB in various aquatic products at the level satisfying the PLS and could contribute to the establishment of the PLS in South Korea.

본 연구는 회복지향의 통합재활프로그램이 만성정신분열병 환자의 증상, 인지 사회적 기능, 재활동기, 정신건강회복수준에 미치는 효과를 검증하고자 시도되었다. 이 프로그램은 인지분화, 정서관리, 직업재활, 가족교육으로 구성된 4개의 소프로그램과 함께 동기강화프로그램이 포함되어 있다. 연구대상은 지방소재의 일개 국립병원에 입원한 정신신분열증 환자로, 실험군 18명과 대조군 16명으로 구성된 비동등성 대조군 전후시차 설계를 사용하였다. 수집된 자료는 SPSS 12.0을 이용하여 통계 분석하였다. 프로그램의 효과를 검증한 결과, 인지 사회적 기능에 별다른 효과를 나타내지 못했으나, 재활동기수준(유지단계에서 p=.027)과 정신건강회복수준(p=.039)에서만 실험군과 대조군에서 유의한 차이를 나타내어 제한적인 효과를 나타내었다. 입원세팅에서 단기간의 회복지향의 통합재활프로그램은 증상감소나 기능향상보다는 재활 동기나 정신건강회복수준을 향상시키는데 보다 효과적으로 활용될 수 있는 가능성이 있는 것으로 보인다. 임상세팅에서 보다 회복지향적인 서비스를 제공하기 위한 노력이 필요하다.

The new movement towards green chemistry and renewable feedstocks makes microbial production of chemicals more competitive. Among the numerous chemicals, organic acids are more attractive targets for process development efforts in the renewable-based biorefinery industry. However, most of the production costs in microbial processes are higher than that in chemical processes, among which over 60% are generated by separation processes. Therefore, the research of separation and purification processes is important for a promising biorefinery industry. This review highlights the progress of recovery processes in the separation and purification of organic acids, including their advantages and disadvantages, current situation, and future prospects in terms of recovery yields and industrial application.
