ATM 망에서 ABR 서비스를 위한 개선된 폭주제어 방법

진광윤,홍주희 三陟大學校 1998 論文集 Vol.31 No.1

ABR(Available Bit Rate) service has highly burst traffic and is not affected by transmission delay but by loss of cells. Because of this performance, it is used effectively in data service of high-speed LAN. In this paper, performance of ABR traffic and control mechanism proposed for ABR service are evaluated. And through improvement of EPRCA(Enhanced Proportional Rate Control Algorithm), model is proposed, which has two thresholds according to cognestion status generated by every switches. One threshold controls transmission rate by use of EPRCA mechanism, and the other controls transmission rate by the giving Backpressure to source and previous switch. Through the use of Backpressure mechanism, fairness of bandwidth allocation between ABR service is maintained as same as EPRCA. And the simulation results show that wide variety of the buffer size is decreased because of more efficiency control in despite of length of distance.

삼차신경절의 뉴런이 구강악안면영역에서의 촉각, 압각,온도각 및 통각 등 다양한 감각을 중추신경계로 전달하는 역할을 하는 것은 주지의 사실이다. 이러한 신경전달에 있어서 이온통로는 감각정보를 전달하는데 핵심적인 역할을 수행하며 특히 소디움 통로는 활동전위의 발생에 중요하다. 소디움 통로는 tetrodotoxin-sensitive(TTX-5) 및 tetrodotox-in-resistant(TTX-r) 통로로 나누어지는 데 이 중 TTX-r 통로에 발생되는 tetrodotoxin-resistant sodium cur-rent(TTX-r INa.)는 capsaicin에 민감한 일차구심신경세포에서 유해자극에 의해 통각신호를 발생시키고 전달하는데 중요하다. 또한 칼슘 통로는 시냅스 전토에 있어서 필수적인 역할을 수행하고 있다. 한편 치과영역에서 치수의 진정 목적으로 eugenol이 흔히 사용되고 있다. 그러나eugenol의 그 작용 기전에 대해서 현재까지 이온통로에 대한 상세한 결과가 없는 실정이며 최근의 보고에 의하면 eugenol이 capsaicin수용기를 통하여 감각신경에 대한 억제작용을 나타낸다고 한다. 따라서 본 실험은 eugenol과 capsaicin이 흰쥐의 삼차신경절의 TTX-r INa와 칼슘통로에 어떠한 영향을 미치는지를 알아보고 eugenol이 capsaicin 수용기를 통하여 작용하는지를 검증하고자 시행되었다 삼차신경절 뉴런은 100-150g의 흰쥐의 삼차신경절로부터 외과적으로 절제하여 통법의 화학적 및 기계적 처리를 통해 단일세포로 분리하였고 이를 Whole-cell patch clamp 방법을 이용하여 시행한 바 다음과 같은 결론을 얻었다. 1.1mM의 dugenol은 흰쥐 삼차신경절 뉴런의 TTX-r INa.와 HVA INa.를 억제하였다. 2.1㎛의 capsaicin은 흰쥐 삼차신경절 뉴런의 TTX-r INa 와 HVA INa 를 억제하였다 3.Capsazepine은 capsaicin의 HVA ICa 에 대한 억제작용을 차단하였다. 4.Capsazepine은 capsaicin의 HVA ICa .에 대한 억제작용을 차단하지 못하였다. 결론적 으로 eugenol과 capsaicin은 tetrodotoxin-resistant sodium current(TTX-r INa )와 high voltage-activated calcium current(HVA ICa )를 모두 억제하는 것으로 나타났으며 , 이러한 작용이 통각의 발생과 시냅스 전달과정을 차단하여 치수 진정 목적으로 많이 사용하는 eugenol의 작용기전으로 판단된다. 한편 capsaicin의 길항제인 capsazepine을 전처치하였을 때에도 eugenol의 HVA ICa 에 대한 억제효과는 변화가 없었다. 이와같은 결과로 보아 HVA ICa 에 관한한 eugenol은 capsaicin 수용기를 통하여 나타나지 않는 것으로 사료된다.

This study was conducted to find out toxicity of compost made of food waste to cucumber seed germination and seedlings growth when it was mixed with Mixlite for bed substrate. Mixlite was solely used as bed soil, or mixed with food waste compost ranging 1% to 100% (w/w). Germination percentage and seedling growth of cucumber were examined in 4 weeks after seedling. When cucumber seeds were sowed in Mixlite mixed with food waste compost at 100, 50, 30, 20, 10 or 1%, germination percentages were 30, 36, 38, 46, 74 and 84% compared to with control(100%), respectively. It showed that germination percentage percentage was adversely affected by the amount of food waste composed mixed in the bed substract. Plant height and hypocotyls diameter, root length and root fresh weight, hypocotyls fresh weight and cotyledon fresh weight of cucumber seedling were similarly adversely affected by the amount of food waste compost. Optimum content of the food waste compost for cucumber nursery substrate was found to be 1% of Mixlite.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.
