매년 폐사가 발생해 온 서해안 연안의 고창과 태안에서 채집한 양식 바지락에서 복합포자충류인 Perkinsus sp.가 관찰되었다. 기생충에 감염된 바지락은 육안적으로 아가미와 육질의 표면에서 유백색의 결절이 나타났다. 기생충의 영양체는 편재된 핵을 가지고 있으며, 아가미와 외투막, 간 췌장, 생식소 조직에서 이분열에 의해 증식하며, 육아종의 형성과 혈구의 침윤을 유발하였다. 감염된 바지락을 FTM에 배양한 결과 영양체의 크기가 커지면서 루골용액에 의해 검게 염색된 구형의 유주자낭들 형성하였다. Perkinsus sp.의 평균 감염율은 9개월의 조사 기간 동안 고창이 73.1%, 태안이 94.8%로 나타났으며, 감염율은 각장의 크기가 클수록 증가하는 경향을 나타내었다. Hemacolor kit는 바지락의 대량폐사와 밀접한 연관이 있는 Perkinsus sp.의 영양체의 신속진단에 유용한 것으로 나타났다.

김치의 가수분해효소로서 발효원으로 사용되고 균체증식에 필수적인 아미노산 생산에 관여하는 단백질분해호소를 생성하는 균주를 분리하여 동정하였다. 시판되는 풀무원 김치의 5종(전라도김치, 숙성김치, 열무김치, 포기김치, 맛김치)에서 단백질분해효소 활성을 지닌 균주 중 곰팡이와 효모를 제외하고 총 9주를 분리하여 whole cell protein pattern 및 API kit 으로 동정하여 각각의 균주들을 Lactobacillus sp. 1종, Leuconostoc sp. 1종, Bacillus sp. 6종, Brevibacillus sp. 1종으로 판정되었다. 분리된 9종과 단백질 분해효소 활성이 높은 표준균주인 Bacillus subtilis KCCM 12248와 Bacillus licheniformis KCCM 11851에 대해 단백질분해활성을 비교한 결과 김치에서 분리되는 K-2(Brevibacillus속)가 0.11 unit/mg으로 가장 높은 값을 보였다.

Objectives & Methods : This study was to investigate effect of low frequency electroacupuncture on NADPH-d positive neurons in the brain cortex of rat with adjuvant induced rheumatoid arthritis. Experimental groups were divided into 6 groups ; Normal, Control, $ST_{36}$, $SP_9$, $ST_{36}+SP_9$ and Non-Acupoint. Normal group, non-arthritic group, was injected normal saline, and the other groups were injected FCA. Each acupoint groups were treated by 2Hz electroacupuncture at each acupoints and NA group was treated by 2Hz electroacupuncture at non-acupoint. Each groups were evaluated by the number of NADPH-d positive neurons in primary somatosensory area(S1), secondary somatosensory area(S2), motor area and caudate putamen by using an image analyzer and a microscope. Results : 1. In S1, the number of NADPH-d positive neuron cells in the $ST_{36}$ group were significantly(p<0.05) increased compared with the control group. 2. In S2, the number of NADPH-d positive neuron cells in all electroacupuncture groups were not significantly changed compared with the control group. 3. In motor area, the number of NADPH-d positive neuron cells in $ST_{36}$ group, $SP_9$ group, NA group were significantly(p<0.05) increased compared with the control group. 4. In Caudate putamen, the number NADPH-d positive neuron cells in all electroacupuncture groups were significantly(p<0.05) decreased compared with the control group. Conclusions : Our result demonstrated that low frequency electroacupuncture on $ST_{36}$ & $SP_9$ normalized expression of NADPH-d positive neurons in the brain cortex of the rheumatoid arthritis model in rats.

It has recently been raised main issue how solve the problem of insufficient energy. One of the solution is to increase the thermal efficiency of power generation system. For the purpose of high efficiency, it is necessary to increase the steam temperature and pressure. So, the use of modified $9{\sim}12%Cr$ steel having superior creep rupture strength and oxidation resistance is required to endure such severe environment. The evaluation of creep properties of those heat resistance material is very important to secure the reliability of high temperature and pressure structural components. Since creep properties are determined by microstructural change such as carbide precipitation and coarsening, It is certain that there are some relationship between creep properties and hardness affected by microstructure. In this study, SP-Creep ruptured test for newly developed 9Cr steel being used as boiler valve material was performed, and creep properties of the material were evaluated. Also, hardness test were performed and hardness results were related to the creep properties such as LMP and creep strength to verify the availability of SP-Creep test as creep test method.

This paper describes the high temperature creep characteristics for virgin material of 9Cr1MoVNb steel using small punch creep(SP-Creep) test technique which is developing recently. In addition, the several results of SP-Creep test are compared with that of 2.25Cr- 1Mo steel which is widely used as boiler materials and that of conventional uniaxial creep test. The obtained SP-Creep curves show the creep behaviors of three regimes like that obtained from conventional uniaxial creep test, and SP-Creep properties are definitely depended on applied load and test temperature. The correlation of SP-Creep rate and creep rupture life with applied load has been determined like the correlation between creep rate/rupture life and stress in uniaxial creep test, and also is satisfied with Power law. The creep rupture times of newly 9Cr1MoVNb steel are higher than those of 2.25Cr1Mo steel at the same creep temperature and applied loading condition, and the decrease extent of creep rupture life with loads is very lower compared with 2.25Cr1Mo steel.

Terebelliphilus simplex n. gen., n. sp. and Myxomolgus invulgus n. sp. are described from the tubicolous polychaetes found in the intertidal shores in the Yellow Sea. The new genus Terebelliphilus belongs to the family Sabelliphilidae but is characteristic in bearing the reduced segmentations In legs 1-4, an unusual sexual dimorphism in antennule, and the ventral location of genital areas. Myxomolgus invulgus is readily distinguishable from its congeners by the morphological features of rostrum, antennule, mandible, maxilla, leg 4 and female leg 5.

A bacteial strain which can produce the extracellular fibrinolytic enzyme was isolated from Jeot-Gal (anchovy) that was Korean traditional salt-fermented fish. The isolated bacterium was identified to be a strain of Bacillus sp. The optimal medium for fibrinolytic enzyme production was determined to consist of 5 g maltose, 10 g defatted soybean, 20 g sodium chloride, 1.75 g K2HPO4 per liter (pH 7.0)
