  • 본 연구에서는 해양환경공학과 환경교육의 관계를 환경교육을 위한 환경학의 관점에서 고찰해 보고자 한다. 이는 지속가능한 미래를 위한 현재적 실효성을 지닌 해양환경공학과 미래지향적 이상성을 지닌 환경교육의 상호보완적 발전을 위해 필요하다. 이를 위해 최근 제시된 환경교육을 보는 새로운 이론적 관점인 '환경교육 위한 환경학'의 이론적 틀을 바탕으로 해양환경공학의 성격을 분석하여 해양환경공학이 잠재적으로 가지고 있는 환경교육적 성격과 상호 간의 시사점을 밝혀 두 분야가 서로 관계를 가지며 발전할 수 있는 기반을 마련하고자 하였다.

  • Sediment is a useful natural source but deteriorated continually by anthropogenic and industrial sources. Therefore, it is imperative to search a suitable method for improving or restoring sediment quality. Sediment has been tested to identify the effects of some external agents on a polluted area for 28 days. Chemical analysis and total viable counts (TVC) test have been conducted for 4 days interval to assess their performance. The analyses of chemical oxygen demand (COD), acid volatile sulfide (AVS), total phosphorous (T-P), total nitrogen (T-N) indicate that the chemical agents was more efficient to improve sediment quality whereas the microbial agent was more efficient for nutrient releasing from sediment. Oxygen releasing property of the chemical agent was thought to be providing with more congenial environment for the higher growth of the bacterial community than the direct application of microbial agents.

  • Sediment cell is renewable energy which produces electric energy using immanent ingredients or reducing power of marine sediment as natural resources. Also the cell has an advantage that environmental pollution can be reduced through conversion of organic and inorganic contaminants into inert matter with generation of the energy. In this paper, we compared characteristics of electricity generation of the two different sediment cells, and investigated the regeneration effect of the sediment cells with manipulation of the sediment such as mixing and re-positioning. The results showed that 14.1 $W/m^2$ of power was obtained with the aluminum electrode, and the mixing of the sediment could increase the power by 4 $W/m^2$ compared to the control. Also, mixing the sediment has kept electricity for 4 weeks at a relatively constant level, which implied 'fuel regeneration effect'. Meanwhile, the sediment cell was proved to be effective in reduction of COD, which was up to 28.6%.

  • The exhaust gas emission from marine diesel engines is one of the major environmental issues. The authors focus the use of photovoltaic energy for the electric power system on marine ships. This paper proposes an operation method of a photovoltaic/diesel hybrid generating system for a small ship in consideration of the fluctuating photovoltaic power due to solar radiation. The aim of the proposed operation method is to minimize the fuel consumption and storage capacity of the battery. The validity of the proposed control method is shown by the numerical simulation based on the experimental data of the photovoltaic system.

  • Clean plate education program was applied to change students' perception on food waste in the dormitory cafeteria of T campus G university that is located in Tongyeong, in which 408 students joined the program. From survey and food waste monitoring, it was found that clean plate education program was effective to change students' perception as well as action. Half students (50.5%) answered that their eating habit changed, and among them 30.1 % students left a little food on the plate and 13.1% students left no food behind. Many students become aware of the seriousness of food waste issue (84.5%), and 44.2% students were trying to reduce leftover. Food waste generation in cafeteria was 341.9, 576.1, 344.3g/capita/day in 2005, 2007 and 2008, respectively. And this shows that food waste generations were much less than national average data except 2007. Therefore we could conclude that clean plate education program was satisfactory to change students' perception on food and to change their action, and it could be an excellent new approach to resolve a social issue caused by food waste. In order to reduce food waste generation at dormitory cafeteria, food taste and diet should be improved and students' eating habits also should be changed. For this, a practical program like clean plate education should be organized.

  • Chlorination has been the most common antifouling method, but alternatives are under searching. In this article, we report how the hydrogen peroxide could enhance the effect of chlorination to prevent fouling by inhibiting larvae settlement and abatement of mussel colonization or by extinct of them; through marine mussel Mytilus edulis. The addition of hydrogen peroxide shows synergic effect on the veliger larvae (up to 19 folds) and effectively reduces required time of mussel mortality by 8-22%. For resolution of micro- and macro-fouling caused by the marine mussel, as well as diminishing of time and conventional chlorine dose could be important factor in favour of environment and economics.

  • We studied improvement in marine environmental impact assessment and related management systems of coastal sediments that are dredged inshore but disposed offshore. After reviewing and diagnosing the existing assessment procedures and problems, we recommend to design the core assessment items and improve the reliability of assessment byenhancing the quality assurance/quality control (QA/QC) and verification processes. We proposed eco-friendly disposal plan for dredging sediment such as reuse system in land development was explored. A marine environmental database system was established to support the assessment processes. Guidelines for marine research and modelling were proposed for improving assessment of dredging and disposal of coastal sediment. Also, applying of screening and scoping for marine environmental assessment was reviewed.
