최근 수산물에 대한 건강식으로서의 인식이 높아짐에 따라 수산가공 공장에서의 가공율도 해마다 높아져 전체 어체의 약 40∼70％를 차지하고 있는 비가식부인 어뼈, 어피, 어두, 내장 등과 같은 부산물의 증가도 동시에 수반되고 있다. 현재까지 이러한 잔사는 일부만이 사료로 이용될 뿐 대부분은 그대로 폐기되어져 심각한 환경오염을 초래하고 있다. (중략)

식품공장에 있어서 Listeria의 중요성은 식품의 가공 및 저장 중에 균의 생존과 성장에 의해 식중독의 발생을 일으킬 수 있으므로 중요한 문제로 부각되고 있다. 외국의 경우 수산물에서의 L. monocytogenes 분포에 관한 연구보고는 많지 않으나 새우, 게살 lobster tail등의 냉동식품에서 분리 보고되었고(Farber et al., 1991), 특히 훈연 연어 등에서는 자주 보고되고 있다(Cortesi et al., 1997). (중략)

EMMC(Entrapped Mixed Microbial Cell) process which is a kind of active cell immobilizing method was applied to treat fisheries processing wastewater biologically. Kinetic constants were calculated for organic and nitrogen removal and effect of effluent recycling on system performance was evaluated also. Yield coefficient, Y showed relatively low value compared with Y value obtained from conventional activated sludge process. It means that EMMC process can reduce amount of excess sludge significantly compared with conventional activated sludge process. Endogenous respiration coefficient $k_e$ of EMMC process also showed relatively low value compared with that of conventional activated sludge process. Yield coefficient Y, endogenous respiration coefficient $k_e$ and half saturation constant $k_s$ obtained from EMMC process in terms of nitrification were compared with reported value from literature based on suspended growth nitrification system. The value of Y obtained from this study has no difference compared with values obtained from literature review and $k_e$ of this study was low but $k_s$ of this study was high compared than values obtained from suspended growth nitrification system. To evaluate the effect of internal recycling on system performance, system was operated with internal recycling ratio of 1.5Q, 2.0Q, 2.5Q and 3.0Q. increase of internal recycling ratio effect more greatly on improvement of denitrification efficiency than that of nitrification efficiency. Accordingly, optimization of internal recycling ratio has to be based on improvement of anoxic reactor performance.

동해안의 수산 가공업은 전체 가공 산업의 30% 가량을 차지하지만, 그 규모면에서 본다면 매우 영세하며 가내 수공업의 수준에서 벗어나지 못하고 있다. 이러한 원인은 수산물이라는 특수한 원료에서 오는 여러 가지 한계들 특히, 가공 특성이 다른 농산물과는 다르기 때문에 대용량의 자동화 시스템을 갖춘 공장화는 어렵기 때문이기도 하다. 또한, 다양한 먹거리의 등장으로 명태알포, 조미오징어의 매출 단가의 하락과 함께 매출도 아주 줄어들어 영동 지역 수산업이 매우 큰 위기상황이다. (중략)

국내 수산가공공장에서는 수산물 가공 중 콜라겐, EPA, DHA, 무기질, taurine 등과 같은 유용 식품성분의 함량이 많은 부산물이 대량으로 얻어지고 있다. 하지만 이들 부산물은 일부 만이 사료 등의 비식용 원료로 이용되고 있을 뿐이고, 대부분이 폐기 되고 있어, 이의 유효 이용이 절실한 실정이다. 한편, 갑오징어는 연체동물 중에서 오징어 다음으로 생산량이 많으면서(the fisheries association of Korea, 1997), 오징어에 비하여 조직감이 특이하여 소비자들의 호응도가 좋아 소비량은 점차 증가하리라 전망된다.

In this study, the feasibility of simultaneous removal of organic materials and nitrogen in the waste-water from fisheries processing plant was evaluated using entrapped mixed microbial cell technique(EMMC) process. The experiment was performed using activated sludge from municipal sewage treatment plant which was immobilized with gel matrix by cellulose triacetate. It was found that the stable operation at the treatment system which is composed of anoxic and oxic tank, was possible when the organic and nitrogen loading rates were increased stepwise. The organic and nitrogen loading rates were applied from 0.65 to $1.72kgCOD/m^3/d$ and from 0.119 to $0.317kgT-N/m^3$ with four steps, respectively. The maximum nitrogen loading rate which could satisfy the regulated effluent standard of nitrogen concentration, was $0.3kgT-N/m^3/d$. The removal efficiency of total nitrogen was decreased apparently as increasing nitrogen loading rates, whereas the removal efficiency of ammonium nitrogen was effective at the all tested nitrogen loading rates. Therefore, it was concluded that nitrification was efficient at the system. Nitrate removal efficiency ranged from 98.62% to 99.51%, whereas the nitrification efficiency at the oxic tank ranged 94.0% to 96.9% at the tested loading rates. The removal efficiencies of chemical oxygen demand(COD) and those of total nitrogen at the entire system ranged from 94.2% to 96.6% and 73.4% to 83.4%, respectively.

This study aims to suggest methods to estimate the agriculture related added value created in the agricultural production sector and the up/downstream agribusiness of Chungcheongnam-do by using the transaction table at producer's price, the domestic transaction table, the wholesale-retail profit table and the freight charge table in the input-output tables, and further aims to estimate regional and industrial agriculture related added values created in the agricultural production sector and the agribusiness of Chungcheongnam-do by using the input-output tables of the year 2005. This thesis suggests the consideration of overall and holistic policy regarding public welfare facilities in healthcare, commission sale market places for fishery products, fishery processing factories, processing factories for medicines, cosmetics, feedstuff, and tobacco leaves and the innovative distribution system with regard to wholesale/retail that Chungnam lacks in. It is also proposed to make comprehensive and cohesive policy to enhance growth and competitiveness of agricultural, forestry and fishery industry.

유조선의 빈번한 왕래로 발생되는 원유의 누출사고, 무절제한 해안환경 파괴 및 생활하수, 공장폐수의 방류 문제가 최근 대중매체를 통하여 빠짐없이 보도되고 있으며 또 그로 인하여 양식장, 바다낚시, 해수욕장 등 생산 및 생활 환경이 오염되어 일반인들도 직접 간접으로 적지 않게 피해를 입게 되므로 그에 대한 관심이 날로 증가되고 있다. 동해 어항의 경우는 수산물 가공폐수 외에 주변에 주거지 및 상가(횟집) 등이 위치하여 생활오수 등이 다량 발생하고 있다. (중략)

Chitosan was prepared from chitin which was abstracted from wasted crab shells. Then itaconic acid was graft-copolymerized onto chitosan using ceric ammonium nitrate as a reaction initiator. To investigate the optimal grafting conditions, the influences of several factors on the grafting were studied, i. e., the concentrations of CAN and itaconic acid, the reaction temperature and time. And to find out its flocculation ability. the flocculation test was carried out with a metal plating factory waste water. The state of graft-copolymer was identified through IR spectra analysis. The optimal grafting conditions and flocculation results were shown to be : concentration of ceric ammonium nitrate is $3.5{\times}10^3M$, reaction temperature is $40^{\circ}C$ and reaction time is 4hrs with 0.25M of the monomer(itaconic acid). Though flocculation tests using chitosan, grafted chitosan and cation, CODcr. metal ions removal rates were measured. The order of superiority is Itaconic acid grafted chitosan>Chitosan>Cationic polymer.
