Anisakid larvae were found from the liver and stomach of the codfish (Notothenia negzecta) caught from the Antarctic Ocean, South Pole, where the Polar Research Center of The Korea Ocean Research and Development Institute is operating- Through observations by scanning electron (SEM) and light microscopy (LM), they were identified as the third stage larvae of Pseunotewnnovo necipiens, a potential agent of human codworm anisakiasis. They measured 25.0-28.5 mm in length, and 0.6-0.8 mm in width. The SEM revealed a prominent boring tooth, three lips, and excretory pore at the anterior end, and a small but prominent mucron at the posterior end. From whole mounts and cross sections of the larvae the ventriculus, intestinal cecum and a Renette cell were found characteristically at the same plane. Raw eating of the codfish caught from the Antarctic Ocean near the South Pole should be avoided so as to prevent human codworm anisakiasis in this area.

For a general ingredients analysis and E Coli-form bacteria surveyed on the marketed milk, samples of bottled milk produced by four different companies were collected in Cholla Buk-do area and examined. The results are: 1) In water content samples A and C exceeded the standard slightly whereas B and D were good. 2) The contents of crude fat and crude protein of all samples were slightly higher than the standard. 3) All samples were deficient in contents of the crude ash and lactose. 4) In spite of the winter, all samples contained more coli-form bacteria than the standard allowance. Through the above results, it could be seen that all samples of marketed milk were a little poor in the contents of general ingredients and contained more coli-form bacteria than the standard allowances. Therefore, considering the general trends of increasing milk consumption and its influence on the national public health. it is necessary for the milk manufacturer to try to streng hen the scientific inspection and improve, the handling of milk products during the distribution.

This experiment was conducted to investigate the effect of transfer date to a growth chamber and low temperature on growth and flowering of Jeffersonia dubia for free control of flowering period. According to transfer date, any plant did not sprout when plants were put in a growth chamber from Aug. 20 to Dec. 20. However, all the plants which were put in a growth chamber on Jan. 20 or Feb. 20 sprouted and resulted in flowering. The effect of beginning time and period of low temperature treatment were also observed. At the beginning time of Aug. 20, sprouting and flowering occurred as plant received more than 60 days of low temperature treatment. However, almost of al l the plants sprouted and flowered by only 30 days of low temperature treatment when the low temperature was given after Sep. 20. 60 days of low temperature given again after about three month growing period after dormancy breaking, resulted in resprouting of all plants and 70% of them flowered in this experiment.

전 세계적으로 기후변화 및 다양한 삶의 패턴이 변화되면서 예상되는 자원의 부족을 해결하기 위한 많은 노력이 진행되고 있다. 특히 범 국가적으로 지속가능한 자원안보 실현을 위한 적정 솔루션을 제공하고 자원의 연계에 따른 효율성과 효과성을 극대화하기 위해 물, 에너지, 식량의 연계를 통한 기술을 개발하고 적용하고 있으나, 아직까지 국가단위의 대규모 사례는 부족하며, Community Scale의 형태로 진행되고 있는 실정이다. 본 논문에서는 국내에서의 물, 에너지, 식량의 연계 기술을 도출하기 위해 국외에서 진행되고 있는 기술에 대한 현황과 효과를 분석하여 국내의 적용방안에 대해 분석하고자 한다. 국외의 사례로는 프랑스 전력공사(EDF)에서는 2000년 초반 기존의 규정대로 물공급을 지속하면 발전에 어려움이 발생하는 것을 인식하여, 주요 농업 관개시설과 물절약협약을 체결하고 물절약에 따른 금전적 보상대책을 마련하였다. 이를 통해 물 절약의 30%는 기존의 관행과 관리방식의 변화에 의해 이루어졌고, 약 70%는 효율적 물 사용기술을 통해 절감효과를 도출하였다. 또한 관개용수와 발전량의 효율적 물사용을 통해 3억2,500만$m^3$에서 2억3,500만$m^3$ 으로의 절감효과를 달성할 수 있었다. 오스틴 수도회사, 텍사스 가수 서비스, 오스틴 에너지 회사 등 텍사스의 3개회사가 상호 협약을 통해 다가구 에너지 및 물효율 프로그램을 개발하고 자원을 효율적으로 관리할 수 있는 주택을 개조하여, 연간 470만 kWh의 전기와 3,785만 리터의 물을 절약하고 있다. 베트남 Red강의 경우 베트남의 근대화 및 산업화를 위해 많은 물과 전기가 필요함에 따라 물사용량을 규제하였고 이로 인해 농작물 재배를 고려하여 장기적이고 다방면적인 전략을 도출하였다. 정유회사 CHEVRON에서는 미국 캘리포니아에서 오일 1배럴을 생산할 때마다 10배럴의 물을 생산하여 오일생산 과정에 이용하며 $182km^2$ 면적의 농장에 농업용수를 공급할 수 있었다. 특히, California 오일 추출과정에서 물과 오일을 분리하고 그 과정에서 발생한 물을 재이용하기 위하여 수처리과정을 통하여 매일 $2,650m^3$의 물 생산하게 되었다. 이러한 외국의 사례들을 바탕으로 하여 국내에서도 다양한 형태의 넥서스 기술을 접목하여 미래에 예측되는 자원 부족을 선제적으로 대응하는 방안을 수립할 때이다.

The corrosion of structural steel used in the construction industry is increasing due to the industrialization where many aggressive ions released in the atmosphere. Therefore, in the present study Al coating was deposited by arc and plasma arc thermal spray process and compared their effectiveness in simulated weathering condition i.e. Society of Automotive Engineers(SAE) J2334 solution which mostly contain Cl^- and CO₃^2- ions. Different analytical techniques have been used to characterize the coating and draw the corrosion mechanism. The Al coating deposited by plasma arc thermal spray process exhibited uniform, dense and layer by layer deposition resulting higher bond adhesion values. The open circuit potential(OCP) of Al coating deposited this process is exhibited more electropositive values than arc thermal spray process in SAE J2334 solution with immersion periods. The total impedance of plasma arc thermal spray process exhibited higher than arc thermal spray process. The corrosion rate of the plasma arc thermal sprayed Al coating is reduced by 20% compared to arc thermal spray process after 23 days of immersion in SAE J2334 solution.

This study classified the types of major forest vegetation and analyzed the syngeographical characteristics of the vegetation in the Mt. Deokhang with exhumed lime rocks. The forest vegetation on the ridge of Mt. Deokhang was classified into 1 community group, 3 communities, 2 groups, and 2 subgroups, 5 types in total. The syngeographical form of Deokhangsan fully exhibited the topographical peculiarity, proximity to subalpine, and limestone zone. In addition, Carex ciliato-marginata, Carex humilis var. nana, and so forth which appear as species with high consistency in the well-drained semiarid zone represent the soil environment of the lime stone area and northern plants such as Carex ussuriensis and Asplenium ruta-muraria represent the characteristics of the vegetation in alpestrine in close proximity. Moreover, the Carpinus turczaninowii in the area appears to show the characteristics of migratory vegetation due to the peculiarity of the habitat. The syngeographical characteristics of this study area show both the characteristics of the habitat and phytogeographic characteristics. Furthermore, they are expected to contribute to the diversity in community and habitat form in Korean peninsula in terms of vegetation science.

In order to compare the quality of canned pork products which are called collectively as luncheon meat, residual nitrite, sodium, collagen, total heme pigments and chemical composition were analyzed in 12 products of 8 companies from 4 countries. Also, the proteins of products were compared with that of pork by SDS-PAGE analysis. The level of residual nitrite was low in all the products and sodium levels were similar except in one or two products. As for collagen and total heme pigments content, among imported products luncheon meats were different from chopped meat products while domestic products were similar regardless of label distinction. Collagen contents of domestic products were similar to those of imports but total heme pigments contents were much higher Densitometer scans of gel electrophoretograms of chopped meat were more similar to that of pork than those of luncheon meat. In terms of chemical composition, luncheon meat had more carbohydrate regardless of whether they are domestics or imports. The quality of domestic luncheon meat appears to be the composite of those of imported luncheon meat and chopped meat. Accordingly, the quality standard for luncheon meat as a cheap product should be established in Korea to enable the domestic products to have a competitive power in price.
