Analysis of VolP-Associated Accounting based on Quality-Based Billing

Jung,Youn-Chan 가톨릭대학교 자연과학연구소 2005 자연과학논문집 Vol.26 No.-

Existing accounting functions on the AAA architecture mainly deal with metering connection time between set up and tear down. This paper presents the VolP-associated accounting architecture which enables quality based billing. The NAS functions as an end-user server to collect accounting packets on a real-time basis and as an accounting client to send a batch to the AAA server. In order to explore the operational burden of placing the function of VolP-associated data collection on the NAS, we will develop an analytical model to investigate the effects of the frequency of accounting packet generation, the number of active devices, and NAS processing capabilities on the performance of the packet loss probability and the packet buffering delay at the NAS buffer. Then, we discuss these results focused on the maximum number of active devices the NAS can accommodate for a certain condition.

This study aim at examining the system and characteristics of Soon-Am. An Jung-Bok's elementery edcational thought is very various. His important elementery thought is integrated in problems of daily life, reading, mind control, behavior, human relations and so on. The system of Soom-Am's elementary educational thought is as follows; he is a confucian scholar whose that is based on the neo-confucianism fundamentally, but he rejected resoltely the impractical theories of that. And his the elementary edcational thought is pratical. The characteristics of Soon-Am's the elementary educational thought are as follows: First, it is the education that point for education for living. Seond, it is the education that is linked with knowledge, character and attiude. Third, it is the education that think, act and pratice according to fixing one's am in life. Fourth, it is the education that take a serious view of the human relations

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Rheumatoid arthritis frequently involves the cervical spine and may lead to neurologic impairement. However, direct involvement of CNS structures by inflammatory cells has been reported infrequently. The prevalence of this complication of rheumatoid arthritis is unknown. Inflammatory CNS involvement in rheumatoid arthritis reportedly occurs in the setting of longstanding, active, erosive articular disease and is accompanied by extracranial and extraspinal nodules and vasculitis. This is diagnosed by radiologic finding of CNS nodules or meningeal thickening and by biopsy or autopsy. Treatment with corticosteroid, cytotoxic agent or surgical decompression is helpful. But the majority of patients die within several months of onset of neurologic symptom. Recently, we experienced a case of pachymeningitis caused by rheumatoid arthritis, which resolved repeatedly with azathioprine treatment.

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.

The Multiple Hypotheses Tracking (MHT) algorithm has been shown to be one of the most cost- effective estimation schemes for hybrid systems. Its performance, however, could only evaluated via expensive Monte-Carlo simulations. An effective hybrid approach to the performance evaluation without recourse to simulations is presented here. This approach is based on a scenario-conditional performance measure of hybrid nature in the sense that it is a continuous-valued function of a discrete-valued random sequence. The performance measure is calculated efficiently in an off-line recursion.

As the length of bridges are getting longer recently, use of modulr expansion joints incorporating huge bridge movements are increasing. In this study, the research was performed for the basic elements of a modular joints, their mechanical behavior, and the structural analysis for a failed modular joint during service life. Based on the theoretical and experimental research results, it is found to be extrely important that fatigue behavior must be considered and very careful installation must be needed for modular joints. An analytical result for a failed modular joints showed that a damage on rubber spring is a main cause for an early failure which results possibly from poor installation.

Clothing and Textiles was introduced in the 1950s to Korea and has been developed. At this moment, it seems to be valuable to identify state of art of researches in clothing and textiles field. The purpose of the study was to investigate trends of subject-matter emphasis in clothing and textiles. The data were included clothing and textiles related research articles published in three professional journals from 1959 through 1990 and condensed at 5 year intervals. The identified 620 articles with clothing and textiles subject-matter emphasis were categorized in six areas: clothing construction, textiles, history of costume, design and aesthetics, sociopsychological aspect of clothing, and fashion merchandising. The results were as follows: 1. Since 1959, there has been a significant growth in terms of the number of research as well as in quality of research particulary considering the short history of the field. 2. The number of each area research was ranked as follows: 1) textiles (217) 2) history of costume (173) 3) socio-sychological aspect of clothing (88) 4) clothing construction (79) 5) fashion merchandising (34) 6) design and aesthetics (22) and others (7) 3. In the area of textiles, the most dominant area was clothing management (102 out of 217) and clothing hygenics research was getting increased from the late of 1980 through journal of the Korean Society of Clothing and Textiles. 4. In the area of history of costume, most of the research have been published through Journal of Korean Costume Society. History of korean costume was the most dominant area (120 out of 173) and history of eastern costume area was getting increased from the late of 1980s. 5. In the area of socio-psychological clothing, the research was accelated in the beginning of 1980s through Journal of the Korean Society of Clothing and Textiles, while the research was decreased a little in the late of 1980s. 6. In the area of clothing construction, it was revealed its decrease the percentage of total number of research and most of them were published through journal of Korean Home Economics. 7. In the area of fashion merchandising, there has been continuous increase in the number of research from the late of 1970s to 1990, present. For the future direction, implications for interdisciplinary and ecological approach were suggested.
