본 논문에서는 메트로 옵티컬 이더넷의 소프트웨어 구조에 관한 연구를 위하여 10기가 비트 이더넷 스위치에 적용될 QoS 지원 소프트웨어의 적용성을 자원할당 방식 시그널링 프로토콜인 RSVP와 트래픽 특성에 따라 CoS를 구분하는 DiffServ가 10 기가비트이더넷 스위치에 활용 가능한지를 네트웍크 프로세스 처리 능력과 확장성 측면에서 분석하였다. 결론적으로 RSVP, Diffserv와 802.1p는 구현 및 상혼 연동이 가능하다. 그러나 이것은 기업 내부망으로 한정된다는 단점을 가지고 있다. 일반적으로 중소규모의 특정 기업의 내부망에 위의 기술들을 구현하는 것은 어려움이 없다. 그러나 공중망에서의 적용은 아직까지는 어려움이 많이 존재하며 서비스 제공자간의 연동은 거의 불가능하다. 따라서 이러한 기술들은 End-to-End QoS를 보장하는 것에 목적을 두고 있다.

These experiments were performed to investigate the effects of plant growth regulators on the tissues culture of red pepper. The best callus growth was observed in Murashige & Skoog's media containing 0.2-2.0㎎/l 2, 4-D plus 0.2㎎/l kinetin or BA on the segments of hypocotyl and cotyledon of red pepper. On the medium with 2.0㎎/l zseatin and 0.01㎎/l 2, 4-D somatic embryos were differentiated from embryogenic cell of immature embryo by suspension culture after 5 week-culture and 8 weeks later they were developed into plantlets, while on the medium with 1.0㎎/l BA and 0.05㎎/l NAA the shoot and root were differentiated from callus mass. The addition of brassinolide retarded the formation of somatic embryo, shoot and root. Key words : Brassinolide - BA - Capsicum annuum(red pepper) - embryogenic callus - 2, 4 - D - kinetin - NAA - somatic embryo - zeatin.

이종장기이식에 의한 면역거부반응에서 IL-18의 역할

Although transplantation immunology as a distinctive field began with the development of experimental models that showed the feasibility of bone marrow tranaplantation (BMT), organ engraftment was accomplished first in humans, and was though for many years to occur by drastically different mechanism. The liver, skin, and gastrointestinal tract are major target organs of acute graft-versus-host disease (GVHD), the major complication of allogenic BMT. The pathophysiology of acute GVHD involves in the dysregulation of pro-inflammatory cytokine cascade and donor T-cell responses to host alloantigens. Interukine-l8 (IL-18) was initially known as interferon-g-inducing factor with potent immunomodulatory effects. The level of IL-18 is increased in acute GVHD, but little has been known about its role in thepathophysiology of acute GVHD. It reduces the severity of acute GVHD as a Thl-inducing cytokine early after BMT to the lethally irradiated recipients. When administered to the donor, it can also reducing the severity of acute GVHD, as a Th2-inducing cytokine. Therefore, IL-18 has the remarkable capacity to modulate acute GVHD when administered either to the donor or the recipient through distinct mechanism. Here, we present our view of the concepts of transplantation immunology and the role of IL-18 in the graft rejection.

In this study, the availability of pig slurry composting and biofiltration (PSCB) solution as an alternative for synthetic nutrient solution was determined by monitoring the growth and phytochemicals of lettuce (Lactuca sativa L. cv. ‘Salanova’). This study was conducted from 16 September 2011 to 31 October 2011. PSCB solution treatments were consisted of 1 time dilution (52N), 13 times dilution (4N), 26 times dilution (2N), and 52 times dilution (1N) which were based on the nitrogen concentration of a commercial liquid fertilizer for leafy vegetables (control). Subirrigation system was used to cultivate lettuce plants in pots containing commercial growing medium. As a result, all growth characteristics were the highest at control. Among PSCB treatments, PSCB 52N induced severe growth disorder at 28 days after transplanting (DAT) probably due to too high salinity. PSCB 1N also retarded the growth of ‘Salanova’ lettuce plants. This may be caused by high pH and/or imbalanced other mineral concentration except nitrogen of PSCB solution. In contrast, polyphenolic compounds with antioxidant properties were more abundant in lettuce with PSCB solution than control. However, further study is required to determine the certain factors of PSCB on the induction of phytochemical biosynthesis pathway. In conclusion, additional strategies should be developed to use PSCB solution as nutrient solution in greenhouses.

The purpose of this study was to standardize the various methods and recipes of Hwajeun (glutinous rice pancake with flower) that appeare in the literature. For this purpose, the effects on sensory and physical characteristics of Hwajeun in various kinds of dipping syrups (S1 : honey, S2 : rice syrup, S3 : com syrup, S4 : sugar syrup and S5 : sugar) during storage for 24hrs were investigated. This experiment consisted of the measurement of water content, color difference meter, texture analyser and sensory evaluation for acceptance (color, flavor, moistness, softness, chewiness, adhesiveness, sweetness and overall acceptability). The moisture contents decreased with increasing storage time, indicating that S1 had a significantly (p<0.01) high value until 12hrs. The colorimetric values of lightness (L), redness (a) and yellowness (b) decreased and the total color difference values (△E) increased with increasing storage time. In the two bite compression test, the hardness of S1 and S3 showed significantly (p<0.001) lower values than other samples. As a result of the sensory evaluation for Hwajeun prepared with various kinds of dipping syrup, S1 and S3 were most preferred in color, flavor, moistness, chewiness, adhesiveness, sweetness and overall acceptability of sensory evaluation.

X-Ray 단결정체 분석에 의한 6,7-디클로로퀴놀린-5,8-디온의 친핵치환반응

서명은,George, Clifford 梨花女子大學校 藥學硏究所 1997 藥學硏究論文集 Vol.- No.6

The compound of the 6.7-dichloroquinoline-5.8-dione has two asymmetric chloro radicals at the position of the C6 and C7. When the compound reacts with ethyl acetoacetate in the presence of sodium ethoxide, it is considered that the C6 and/or C7 position of the compound can be substitued. The exact substitued position of the product (Ⅰ) could not be identified by the NMR analysis in our experiment. Therefore, we synthesized the 3-ethoxycarbonyl-2-methyl-1-N-propyl pyridino (2,3f)indole-4,9-dione by reaction of the product (Ⅰ) with propylamine via intramolecular cyclization to identify the substitued position of the product (Ⅰ) using the X-ray crystallographic structure analysis. The result demonstrates that the the position of nucleophilic substitution of the product (Ⅰ) is at the position of the C6.
