우리나라 해산어 양식의 주요 대상 어종인 넙치의 섭식 촉진 물질을 확인하기 위하여 몇 가지 아미노산, 핵산관련물질, 염기성 물질 및 산가수분해물의 섭식촉진 효과를 수조 실험을 통해 검토하였다. Glycine, IMP, GMP 및 betaine은 다소의 섭식 촉진 효과가 인정되었으며 천연 단백질 자원의 산 가수분해물인 KH가 가장 우수한 섭식촉진 효과를 보였다. KH는 사료 중량에 대하여 $1.05\%$ (w/w)까지 섭식촉진 효과가 증가하였으나 그 이상의 농도에서는 효과가 거의 일정하였다. 산 가수분해물의 pH는 섭식촉진에 영향을 미치지 않았고, 물질의 흔합에 따른 상승효과는 KH와 glycine의 조합이 가장 우수하였다. 대조군 사료는 총 급이량의 $58.2\%$를 섭취한 반면 섭식촉진 사료는 $83.3\%$를 섭취하여 섭식촉진물질의 첨가는 섭식량의 증가 뿐 아니라 사료 효율의 개선에 현저히 기여하였다. 그리고 섭식촉진 물질의 조합에 따른 단가 상승은 기본사료 가격의 $0.05\%$ 이내에 불과하여 경제성이 충분하며 실용화가 가능한 것으로 예상하였다. 한편 본 연구 결과의 적용을 확대하기 위해서는 장차 넙치 성어에 대한 연구도 필요할 것으로 보인다.

Most of life thing including human being have tendency of reaction with inherently their own pattern against environmental change caused by such as light, sound, smell etc. Especially, a sense of direction often works as a very important factor in such reaction. Actually, human or animal lift that can react instantly to a stimulus determine their action with a sense of direction to a stimulant. In this paper, we try to propose how to give a sense of direction to a robot using sound being representative stimulant, and tracking sensors being able to detect the direction of such sound source. We also try to propose how to determine the relative directions among devices or robots using the digital compass and the RSSI on wireless network.

Appetite stimulant ether-soluble neutral extract of a high-grain compound feed was separated into four fractions with an open column of silica gel chromatograph using four carrier solutions containing n-pentane and diethyl ether as 100:0 (Fraction A), 90:10 (Fraction B), 75:25 (Fraction C) and 0:100 (Fraction D). The stimulative effects of the fractions were examined by comparing the intake of hay (with or without the fractions) in two-choice test bioassays with cattle. The Fractions A, B and C of the neutral extract stimulated (p<0.05) hay consumption in cattle, whereas Fraction D had no effect on selective feeding when compared with the control fraction. Furthermore, Fractions A, B and C had higher (p<0.05) feeding stimulative indices (FSI) than that of the Fraction D. The results suggest that chemical stimulants to increase palatability of hay are present in the neutral Fractions A, B and C of high-grain concentrate.

In this study, use to CBS Dust as substitution of cement was explored. And the CBS Dust was intended to be used as a cement substitute, and the possibility as a potential water hardness stimulant for BS was investigated. Test results indicated that it can be used in with BS for a potential hydroponic stimulant.

Intravenous administration of O-acetyliervine (an alkaloid from Vertrum album) produced a dose-dependent (10-100 .mu.g/kg) fall in blood pressure and tachycardia in anaesthetized normotensive rats. Pretreatment of animals with propranolol (1mg/kg) abolished these cardiovascular responses of O-acetyljervine similar to that of isoprenaline $(1\mu/ml)$. In isolated tissue experiments, O-acetyljervine $(10-100\mu/ml)$ produced a dose-dependent relaxation of phenylephrine-induced contraction of the rabbit aorta. In guinea-pig spontaneously beating atria, it caused positive inotropic and chronotorpic responses in a dose-dependent fashion $(10-100\mu/ml)$. These responses were abolished in the presence of propranolol $(1\mu/ml)$ similar to that of isoprenaline. These results indicate that O-accetyljervine is adrenoceptor stimulant $(\beta_1\; and\;beta_2)$ like isoprenaline.

Background: Toll-like receptors (TLRs) have been extensively studied in recent years. However, functions of these molecules in murine B cell biology are largely unknown. A TLR4 stimulant, LPS is well known as a powerful polyclonal activator for murine B cells. Methods: In this study, we explored the effect of a murine TLR9 stimulant, M6-395 (a synthetic CpG ODNs) on B cell proliferation and Ig production. Results: First, M6-395 was much more potent than LPS in augmenting B cell proliferation. As for Ig expression, M6-395 facilitated the expression of both TGF-${\beta}1$-induced germ line transcript ${\alpha}$ ($GLT{\alpha}$) and IL-4-induced $GLT{\gamma}1$ as levels as those by LPS and Pam3CSK4 (TLR1/2 agonist) : a certain Ig GLT expression is regarded as an indicative of the corresponding isotype switching recombination. However, IgA and IgG1 secretion patterns were quite different--these Ig isotype secretions by M6-395 were much less than those by LPS and Pam3CSK4. Moreover, the increase of IgA and IgG1 production by LPS and Pam3CSK4 was virtually abrogated by M6-395. The same was true for the secretion of IgG3. We found that this unexpected phenomena provoked by M6-395 is attributed, at least in part, to its excessive mitogenic nature. Conclusion: Taken together, these results suggest that M6-395 can act as a murine polyclonal activator but its strong mitogenic activity is unfavorable to Ig isotype switching.

This study was designed to figure out current situation of use of non prescription drugs and psychological factors of high school girl students on drug use, and conducted from Nov. 1 through Nov. 20. 1998. 536 girl students were randomly selected for this study. Symptom Check list-90-Revision questionnaires used for interview. The data obtained were analyzed by SAS program. The results are as follows: 1. 94.8% of students had experiences of using more than one kind of drug; lenitive(57.8%), digestant(74.1%), remedy for colds(84.9%), antibiotic(9.3%), stimulant(3.2%) remedy for constipation(22.4%). 2. Students had experiences of using non prescription drug, lenitive(88.1%), digestant(91.7%), remedy for colds(57.4%), antibiotic(58.0%), stimulant(88.2%) remedy for constipation(88.3%) 3. 19.4% of students had experiences using drugs more than one time a week and 23.5% of students experienced tolerance, prescription group(11.1%) and non prescription group(88.9%) and 21.4% of students were keeping some medicine who experienced tolerance. 4. The scores of Symptom Check list-90-Revision of students' were higher than Kim's standard group and the psychological states were worse than Kim's standard group. 5. There were significant differences among groups(no use of drug, use of less than three kinds of drugs, use of more than three kinds of drugs) in Symptom Dimension without Paranoid Ideation and Phobic Anxiety and between using group and non using group of drug in Psychological factors on Drug use by lenitive, antibiotic, and stimulant.

환경오염 저감을 위해 순환유동층 보일러를 활용한 발전이 증가함에 따라 CFBC 플라이애시가 많이 생산되고 있다. CFBC 플라이애시내는 수화반응 중 시멘트의 팽창과 급격한 초기응결을 발생시킬 수 있는 free CaO를 포함하고 있기 때문에 콘크리트에서의 사용이 제한적이다. 본 연구에서는 고로슬래그시멘트의 초기강도 증진을 위해 CFBC 플라이애시와 인산석고와 같이 혼합함으로서 천연석고를 대체하는 자극제로 활용하고자 하기 위하여 미세구조와 초기강도 특성을 실험적으로 분석하였다. 인산석고는 배면탈황석고와 인산중화석고를 사용하였으며, 이수상태와 무수상태로 각각 혼합하여 실험하였다. 실험결과 CFFA와 dihydrate 형태의 이수석고를 혼합하는 경우에는 상대적으로 초기강도 발현이 낮아지나, CFFA와 anhydriteII 결정형태인 무수인산석고를 혼합한 배합의 강도 증진효과가 천연석고를 사용한 경우와 유사하여 혼합시멘트로 활용 가능성이 높은 것으로 분석되었다.
