The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based o the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

In this paper, we propose a new weaving trajectory algorithm for the are welding of a articulated manipulator. The algorithm uses the theory of Bezier spline. We make a comparison between the conventional algorithms using Catmull-Rom curve and the new algorithms using Bezier spline. The proposed algorithm has been evaluated based on the MATLAB environment in order to illustrate its good performance. Through simulations, the proposed algorithm can result in high-speed and flexible weaving trajectory planning so that it s trajectory cannot penetrate into a base metal compared to the conventional algorithm using Catmull-Rom curve.

This study is aimed to identify effects of import liberalization of chicken products not only on agriculture but also on national economy overall. The extending influences on production and income are generally measured using input-output analysis tool. But the reaction induced by import liberalization of chicken products would not be considered in the open static input-output-model, far example multiplicator effects between income and consumption. In order to overcome the defect of the open static input-output-model, the open static Leontief-model is extended to the income-consumption relation in measuring the extended effects of the import liberalization of chicken products. This study is undertaken using the results of KREI(Jan. 1994) which concluded that the direct losses in agriculture from 1995 to 2001 could be 113 billion won at the constant price of 1990. It was calculated that the indirect production losses of the other related industries could be 165 billion won, and 246 billion won in the view of income-consumption relation. It was also predicted that the indirect income losses of the other related industries would be 89 billion won, and 126 billion won in the view of income-consumption relation. As a result import liberalization of chicken products could possibly bring about larger losses to the other industries than to agriculture. Especially, in the "Other flood preparations" sector, the indirectly largest loses could predict to be occured.

금속산화물들은 각종 산업재료로서 유용하며 더욱이 그것들의 결정형 나노입자를 경제적으로 제조하는 기술은 21세기 첨단산업에 매우 중요하다. 저자들은 前報에서 화학합성법에 의한 각종 금속산화물의 나노입자를 제조하는 표준공정법을 연구하여 보고하였다. 본 연구에서는 그 표준공정법을 이용하여, 가넷의 일종인 BiDy_(2)Fe_(5)O_(12) 결정 나노입자 분말을 제조하고 그것의 자성체로의 응용을 위해 제품특성을 조사하었다. 가네트 제조과정에 필요한 침전물은 제품설계에 의거 몰비로 계산된 Bi, Dy, Fe의 질산염들의 혼합수용액에 침전제로서 pH NH_(3)-NH_(4)CI 완충용액 일정량을 가하여 얻어졌다. 이렇게 제조된 침전은 열처리과정을 거처 BiDy_(2)Fe_(5)O_(12) 결정형 나노입자 분말로 만들어졌다. 얻어진 제품의 입자크기, 조성, 결정구조 및 광자기성 등 특성시험이 SEM, ICP, XRD, 그리고 VSM 등을 사용하여 실시되었다. 각종 분석법을 사용하여 제품의 특성을 조사한 결과, 최초에 설계한 대로의 자성체가 나노 크기의 분말로 얻어졌으며 이것을 통하여 전보에서 확립한 표준공정법의 유효성도 입증되었다. Metallic oxides are useful as various industrial materials. Futhermore, the cost-effective techniques of fabricating the crystalline nanopartides of metallic oxides are very important for the high-tech industries of the 21 century, In the previous study, the authors reported the standard process for the preparation of crystalline nanoparticles of metallic oxides by chemical synthesis, In this study, BiDyzFesOiz nanoparticles were prepared by using the reported standard process and the characteristics of the product were investigated for applicability as magnetic substance. The precipitation needed for manufacturing process of garnet was made by adding the NH_(3)-NH_(4)CI buffer solution of pH 10 to the mixed solution of bismuth (III) nitrate, dysprosium(III) nitrate and iron(III) nitrate. The amount of each nitrate was calculated by the designed mole ratios. The nano-size crystalline powders of BiDy_(2)Fe_(5)O_(12) were earned by heating the precipitation at 800℃ for 4 hours in air. The characterizations, such as particle size, composition, crystal structure and magneto-optical property of garnet were tested by SEM, ICP, XRD, and VSM analyses. The results of the analyses showed the following two facts. First, a good magnetic substance of BiDy_(2)Fe_(5)O_(12) was earned as crystalline nano-size powders according to the original design. Next, the established standard process for the fabrication of METALLIC oxides nanonartieles was approved as a very effective method.

Soybean yellow common mosaic virus (SYCMV) has been recently reported, it has been occurred a lot with Soybean mosaic virus (SMV) and Soybean yellow mottle mosaic virus (SYMMV) in soybean field. SYCMV belongs to genus of Sobemovirus and induced viral symptoms with yellowing, mottle and mosaic. A reverse transcription loop-mediated isothermal amplification (RT-LAMP) method allowed one-step detection of gene amplification by simple procedure and needed only a simple incubator for isothermal template. This RT-LAMP method allowed direct detection of RNA from virus-infected plants without thermal cycling and gel electrophoresis. In this study, we designed RT-LAMP primers named SYCML-F3/B3/FIP/BIP from coat protein gene sequence of SYCMV. After the reaction of RTLAMP, products were identified by electrophoresis and with the detective fluorescent dye, SYBR Green I. under daylight and UV light. Optimal reaction condition was at 63 for 60min and the primers of RTLAMP showed the specificity for only SYCMV tested in this study.

배추 시스테인 단백질 분해 효소 억제 유전자 BCPI-1의 발현과 종자 발아 및 유묘 생장과의 연관성

Phytocystatins are protein inhibitors of cysteine proteinases of the papain family that have been identified in both monocot and dicot plants. A cDNA encoding a phytocystatin, BCPI-1 (Brassica Cysteine Proteinase Inhibitor-1) has been isolated from Chinese cabbage (Brassica campestris L. ssp. pekinensis) flower buds. Here, we tested whether BCPI-1 transcription is regulated by hormones, and could be involved in regulating cysteine proteinases during and after germination. BCPI-1 was sensitive to exogenous GA_(3) and ABA, which are important factors controlling seed germination, suggesting that the expression of BCPI-1 is hormonally regulated. We introduced a recombinant plasmid containing the full-length BCPI-1 cDNA under the control of cauliflower mosaic virus 35S promoter into rice embryogenic calli using the particle delivery method, and regenerated a number of transgenic rice plants. Constitutively over-expressed BCPI-1 caused changes in overall plant growth and development, including reduced germination and seedling growth. These data support the role of the BCPI-1 in the regulation of endogenous proteinases during both seed germination and subsequent seedling development. Phylocystatins은 papain계열의 cysteine 단백질 분해 효소 활성을 특이적으로 억제하는 억제자로 다양한 식물 종으로부터 분리되었다. 본고에서는, 배추 화아 cDNA library로부터 분리된 phytocystatin인 BCPI-1(Brassica Cysteine Proteinase Inhibitor-1)의 생체 내 기능에 대해 연구하였다. 먼저, BCPI-1 전사체는 발아 조절에 중요한 영향을 미치는 GA₃와 ABA에 의해 예민하게 증가, 혹은 감소되는 반응을 보임으로써, BCPI-1이 식물 호르몬의 영향을 받으며, 특히 발아나 유묘의 생장 조절에 관련이 있음을 알 수 있었다. Particle bombardment 방법을 통하여 BCPI-1을 벼의 배 형성 세포 내에 도입, 재분화 시켜 형질 전환 벼를 생성하였다. CaMV 35S promoter의 조절에 의해 지속적인 BCPI-1 발현을 보이는 형질 전환 벼의 경우, 발아와 유묘 생장이 현저히 지연되었다. 위의 결과들을 바탕으로, BCPI-1이 식물체 내에서 생성되는 cysteine 계열의 단밸질 분해 효소 활성을 조절하여 종자의 발아와 유묘의 생장에 영향을 미치는 것으로 추측한다.

It is essential that we put the anticoagulant into the blood specimen of the CBC test. However, the value of some parameters in the CBC test can be changed whenever using some anticoagulants. EDTA anticoagulant is mostly used these days. There are 3 kinds of EDTA, that is K_(2-), K_(3-), and Na_(2-) EDTA. The author studies how many effects each the EDTA gets into the true value of blood specimen for MCV of RBCs. Especially we compared the MCV effect of different concentrations of 3 EDTA anticoagulants on the bias with time and instrument. Some results are gotten. In our results, K_(3-)EDTA anticoagulant shows more satisfactory MCV value than K_(2) or Na_(2-)EDTA. On using concentration of EDTA, 1.5㎎ EDTA/㎖ of blood show more satisfactory MCV value than 7.5㎎ EDTA/㎖ of blood. However, the choice of anticoagulant may be dependant on the different instruments.
