  • The survey revealed that, due to the discharge characteristics of seafood wastewater, irregular inflow loads were caused, making it difficult to treat the wastewater safely. It is crucial for the operation of pressure and floating tanks for the treatment of high-concentration organic wastewater such as seafood wastewater. The survey of operation factors for the pressure and floating tanks revealed this: A/S ratio 0.05 (design criteria 0.01), the pressurized air pressure 8bar(design criteria 6bar), the pressure tank pressure 6bar (design criteria 4.5bar), and HRT 60sec(design criteria: 10sec). Also, the recirculation rate was changed to over 40%(design criteria: 30%), and the surface load rate was changed to under $13.7m^3/m^2{\cdot}hr$(design criteria: under $17.7m^3/m^2{\cdot}hr$); thus, compared to the initial design criteria, the operation factors were changed according to inflow characteristics, thus enhancing the pressure and floating tank performance. The survey of inflow load revealed BOD 140.7%, $COD_{Mn}$ 120.32%, and SS 106.3%, compared to the inflow design criteria, as well as T-N 135.5% and T-P173.3%, higher than the design criteria. The survey of the treatment facility annual operation cost revealed high portions in sludge treatment cost(27.7%) and chemicals costs(26.0%), and the sludge treatment cost will likely further increase due to the ban on ocean dumping. The unit cost for the treatment of seafood wastewater was found to be KRW 3,858 per ton, more than 27 times higher than the sewage treatment cost(KRW 142.6/ton), presumably because the seafood wastewater contains high-concentration organic substances and nutritive salts.

  • Rapid economic development has led seafood consumption to its quality - oriented pattern as well as consumer's in China. This study concerns about The First, China is Seafood development background. The Second, China become emboldened seafood causes. The third, seafood consumption has characteristic. The fourth, seafood consumption has the organization of society. The study shows that there are economic developmental periods Chinas has three time. The First time$(1961\sim1983)$ is rapid growth. The Second time$(1984\sim1998)$ is growth accumulate. The third time$(1999\sim)$ is changing on seafood consumption as the consumption of seafood is changed according to economic variables changes in income, price, tastes and population. This changing pattern of seafood consumption is based on economic variables appears toward luxury and convenience seafoods. Consumption of food is also affected by non - economic variables. The most typical non - economic variables leading to changes of seafood consumption is local, seafood culture, $et{\ldots}$ Recently seafood consumption pattern shows that consumers paying more money to get their seafood preference for pursuing its hight growth and varienty.

  • Phosphate removal through adsorbent, such as activated alumina, powdered aluminum oxide, flyash, blasted furnace slag and other materials, is commonly and widely practiced. The purpose of this study was to improve the removal efficiency of phosphorus in waste sludge earned at seafood processing factories. To investigate the utility and the feasibility of this sludge disposal process, experiment was carried out with a batch process. As a result, phosphate removal appears to increase with increasing adsorbent does, but shows no changes at an adsorbent does over 5g/l. With increasing ratios of initial phosphate concentration to adsorbent does, the amount of removed phosphate is increased while phosphate removal(%) is decreased. Wasted sludge, treated with zinc chloride chemically, represented a better efficiency than the untreated activated sludge and zinc chloride itself, when they reacted with phosphate solution.

  • 우리나라에서는 70년대 중반 여후 공공요금관리(公共料金管理)가 물가정책의 주요수단으로 인식되어 왔으나, 다른 나라의 경험을 살펴보면 물가상승압력(物價上昇壓力)의 근본적인 해소가 전제되지 않는 가격규제정책(價格規制政策)은 유효한 물가대책(物價對策)이 아니라는 것이 보편적으로 인정되고 있다. 본고(本稿)의 분석(分析)에 의하면, 공공요금(公共料金)의 변동과 기타물가지수(소비자물가지수에서 공공요금 및 농축수산물지수를 제외한 것)의 변동간에는 장기적으로 같이 움직이는 공적분관계(共積分關係)가 존재한다. 그러나 일반의 인식과는 달리 공공요금의 변동이 기지물가변동(其地物價變動)을 초래하는 것이 아니라, 기타물가상승(其他物價上昇)이 공공요금상승을 유발하였던 것으로 나타났다. 이는 과거의 공공요금관리정책(公共料金管理政策)이 물가대책으로서의 유효성은 높지 않았음을 의미한다. 따라서 향후의 물가안정(物價安定)은 공공요금 등에 대한 직접적인 가격억제(價格抑制)보다는 경제전체의 물가상승압력(物價上昇壓力)을 완화시킬 수 있는 안정위주의 거시정책기조(巨視政策基調)를 통하여 이뤄 나가야 할 것이다.

  • This paper tries to estimate Korea's import demand function for fisheries using cointegration analysis. The estimation function consists of one dependent variable-import quantity of fisheries(FTIW) and two independent variables-relative price(RP) between importable and domestic products and real income(GDP). As it has been empirically found out that almost all of time series of macro-variables such as GDP, price index are nonstationary, existing studies which ignore this fact need to be reexamined. Conventional econometric method can not analyze nonstationary time series in level. To perform the analysis, time series should be differenciated until stationarity is guaranteed. Unfortunately, the difference method removes the long run element of data, and so leads to difficulties of interpretation. But according to new developed econometric theory, cointegration approach could solve these problems. Therefore this paper proceeds the estimation on the basis of cointegration analysis, because the quartly variables from 1988 to 1997 used in the model is found out to be nonstationary. The estimation results show that all of the variables are statistically significant. Therefore Korea's import demand for fisheries has been strongly affected by the variation of real income and the relative price.

  • Implementing the automatic identification in supply chain management is essential for effective and efficient process control. Though the GTIN based bar code system is generally used as an automatic identification method in most industries, it can not identify individual item, and is not appropriated for products' reliability and safety management. So the RFID system with EPC is considered as a better solution for resolving those problems. This study reviewed automatic identification code systems and the attributes and characteristics of RFID Gen 2 which became a global standard recently for supply chain management. Particularly, this study analyzed RFID Gen 2 systems' read rates on various conditions including distances between tags and readers and between antennas, condensation, and several packing materials in practical supply chain environment. The results of this study showed that the RFID Gen 2 had high read ratio in practical application and would be adopted as a new automatic identification means for traceability systems.

  • The purpose of this study was to raise some questions about the supply and demand statistics of fisheries products and to find implications for food supply and demand. There are three problems in the statistics of fisheries supply and demand. First, it is a structural problem of supply and demand statistics. Supply and demand statistics are not accurate because the feed, the amount of loss, and the waste rate are not surveyed. Second, the amount of fish used as a moist pellet is missing. Third, although some of the seaweed and kelp production is used as abalone feed, it is not classified as feed. Taking these results into consideration, at least 300,000 tons should be classified as feed for fisheries supply and demand statistics. As mentioned above, the current statistics on the supply and demand of fisheries are incomplete and structural improvement is needed.
