In the present work we introduce a new flare activity indicator, MAD and examine its characteristics by analyzing a set of successive three days' observations of a typical active region, AR2372. The computed MAD is compared with conventional activity indicator such as separator. It is found that. (1) MAD traces very well the separator, (2) it. singles out. local discontinuity of magnetic field lines and (3) it. is a good measure of describing the evolutionary status of active region.

Environment friendly agricultural material products (EFAMs) in current market were evaluated for their insecticidal or acaricidal activities. EFAMs were evaluated against Tetranychus urticae, Plutella xylostella, Myzus persicae and Nilaparvata lugens in spray method. Several EFAMs indicated high control value in spray method. Hatchability of T. urticae was relatively high after EFAM treatment. some materials show high insecticidal activities against P. xylostella larvae but not against eggs. Few meterials showed more than 80% insecticidal activities against M. persicae and N. lugen. The control value of more than half the materials for pest control was lower than 60%. EFAMs containing S. flavescens, neem oil and Rape showed higher control value

The lutropin/choriogonadotropin receptor (LHR) is a member of the rhodopsin-like subfamily of G protein coupled receptor (GPCRs), that has been shown to mediate the internalization of its two naturally occurring agonist, lutropin and choriogonadotropin (CG). The clustered agonist-receptor complex is internalized by a dynamin-dependent pathway and traverses the endosomal compartment without agonist dissociation Dissociation of the agonist-receptor complex occurs in the lysosomes, where both the agonist and receptor are degrade. Recently, constitutively activating mutations of the receptor have been identified that are associated with familial male-precocious puberty (FMPP). A FMPP is a form of sexual precocious puberty in boys in which testosterone levels are elevated independent of changes in luteinizing hormone-releasing hormone and serum luteinizing hormone levels, We have now analyzed two naturally occurring, constitutively active mutants of the human LHR. These mutations were introduced into the rat LHR (rLHR) and are designated L435R and D556Y. Cells expressing rLHR-D556Y bind human choriogonadotropin (hCG) with normal affinity, exhibit a 25-fold increase in basal cAMP and respond to hCG with a normal increase in cAMP accumulation. Cells expressing rLHR-L435R also bind hCG with normal affinity, exhibit a 47-fold increase in basal cAMP, and do not respond to hCG with a further increase in cAMP accumulation. This mutation enhances the internalization of the free and agonist-occupied receptors ~2- and ~17- fold, respectively We conclude that the state of activation of the rLHR can modulate its basal and/or agonist-stimulated internalization. Since the internalization of hCG is involved in the termination of hCG actions, we suggest that the lack of responsiveness detected in cells expressing rLHR-L435R is due to the fast rate of internalization of the bound hCG. The finding that membranes expressing rLHR-L435R respond to hCG with an increase in adenylyl cyclase activity supports this suggestion. Autonomous Leydig cell activity in FMPP is caused by a constitutively activating LH/CGR.

The most change in this century is supposed to be declination of ideology, and block of world economy. Addition to down full of cold war atmosphere around Northeast Asia, not only economic and social mood in this region is dramatically changed, but also it gave birth to the block of Northeast economy that accerlated new hub of world economy. According to dramatic change of economic surroundings the dynamic potential of growth in this region will be guided to enlarge inter-regional trade and increase volume of trade, thus suggests to grow steadily transportation. cargos in this region will have to arrange the system of delivery and inner transportation, accessary facilities, inter-regional harbors if North America and EC has connected easily. As have accerlated GATT and UR represented multilateralism and regionalism, it has regulated to increase trades of region due to relief of the trade barrier through specific areas has agreed with separately. The flow of regionalism of world economy has appeared to realize EC and NAFTA centered U.S.A, and also has presented to free trade region or one-size market agreement in Asia as APEC, EAEG in Malaysia, and etc. In defense to this block and internationalism of world economy, Pusan has to come forward to the hub of Northeast others has proposed a project to dominate the Northeast, Economy Association Agreement as Far East comprehensive development project in USSR, Hunchun development project in NK, and East Sea development project in PRC, Niigate regional development in Japan, Duman River development project in NK, and East Sea development project in Korea. As this exercise has proceed, Pusan also have arranged development strategy definitely and prepared provisions systematically. Engaging to participate center of delivery system is meant to be completed complex functions, namely the transfer storage processing & assembly function of international commodity. Pusan has ability to be terminal point of TSR. it had been connected to EC as the biggest economy block and TKR as complex transportation root to Far East, it would be the center of inground and seabase delivery terminal to Rotterdom as the biggest container pier and major piers to North-East and South East Asia. In order to provide a Role of 21 century's internationalization, Pusan has appealed to participate in management information research and development connected to Pohang-Ulsan-Changwon-Masan, and has utilized efficiently the resources such as man, material, money and information.

1981년부터 최 등이 재래종 옥수수의 수집종 가운데서 병발한 한계통(MET)을 분얼이 많이되고 또한 개체당 이삭(수)수도 많아서 사료용 옥수수의 육종재료로 가치가 있다고 생각되었으나 이 옥수수에 대한 유전적 분석이 확실히 되어 있지를 않았다. 따라서 본연구에서는 MET와 비분얼성이며 이삭도 하나 밖에 달리지 않는 수원 19호 (Mo17 B68) 교잡종을 이용하여 F1 , F2 , BC1 , 세대를 양성하고 Mather의 세대평균분석법에 의하여 분석한 결과 MET 계통의 다수.다얼성은 염색체상의 유전인자에 의한 다기 보다 세포질적 유전인자에 의한다는 것을 확인하였다. 이같은 결론은 MET계통을 모계로 하여 교잡한 려잡종 세대에서 확실히 얻을 수가 있었다. 즉 MET 계통을 모계로 이용했을 때의 평균분얼과 이삭수는 MET를 부계로 이용했을 때의 분얼수와 이삭수 보다 많았는데 이는 이같은 특성들이 모계유전을 하기 때문이다. 그러나 이같은 특성들이 F1 이나 F2 에서 나타나지 않은 것은 F1 에서 특히 보여주는 잡종강세현상 때문에 옥수수의 정부우세성이 매우커서 상반적으로 분얼이나 이삭의 발달이 억제되었기 때문이라고 생각된다. 그리고 분얼이나 이삭의 절대수가 모계로 이용했던 MET에서 보다 잡종세대가 진전될수록 적어지는 것은 잡종강세외에도 MET계통의 세포질약 내지 유전인자적 축적량(Dose)이 적어지기 때문이라고 생각되어진다. 이같은 MET계통의 특성은 려교잡에 의한 MET계통의 세포질을 유지하거나 축적하므로써 사료용 옥수수의 육종에 이용될 수 있을 것으로 보여졌다.에서 조생종이 높은 발아력을 나타냈으나 16℃ 에서는 조, 중, 만생종 간에 발아력 차이가 없었다. 5. 참깨 종자중과 발아율과의 관계는 단일품종 내에서는 종자중이 무거울수록 발아율이 높았으며 평균 발아일수도 단축되는 경향을 보였으나 공시품종들의 천립중의 경중 특성에 따른 발아력 차이는 없었다.e more the silica filler was added, and the lower the gel temperature was in the epoxy system. In this study it is concluded that the curing of the silica filled epoxy system was found to be accelerated, as silica was added to the epoxy compound.ed by adults who are middle-aged or elderly.
