통합 캐시 및 개선된 적응형 세미소프트 핸드오프를 이용한 셀룰러 IP의 성능분석

정승호,김남 충북대학교 컴퓨터정보통신 연구소 2004 컴퓨터정보통신연구 Vol.12 No.2

기존 셀룰러 IP는 많은 중복패킷으로 인하여 네트워크에 큰 트래픽 부하가 가중되고, 패킷 손실과 핸드오프 지연이 발생한다. 본 논문에서는 페이징 캐시와 라우팅 캐시를 결합한 통합 캐시와 중복 패킷 발생을 최소화하는 개선된 적응형 세미소프트 핸드오프를 함께 운용할 것을 제안하였다. 컴퓨터 시뮬레이션을 통하여 패킷 손실, 핸드오프 지연 및 네트워크 내 트래픽 부하 특성 등을 고찰하였다. 그 결과 제안한 방식은 액세스 네트워크 내 노드와 이동 호스트의 수, 노드 내 다운링크의 수가 증가할수록 세미소프트 핸드오프를 적용한 기존의 셀룰러 IP와 비교하여 크게 개선되었다는 것을 확인하였다. Existing Cellular IP increases the network traffic load, packet loss and handoff latency because of duplicate packet. In this paper, we propose using a Combined Cache that unites a paging cache with a routing cache and an improved adaptive semi-soft handoff that minimizes the generation probability of duplicate packet. Through a computer simulation, we consider packet loss, handoff latency and traffic load in network. In proportion to the number of nodes, mobile hosts and downlinks of node in access network increased, the proposed method is largely improved in comparison with existing Cellular IP that uses semi-soft handoff.

비볼록 목적함수에서 M-추정법

남호수,조증성,주철민 東西大學校 1998 동서논문집 Vol.4 No.-

일반적인 위치모수의 추정문제에서 로버스트 방법으로 흔히 고려되는 것이 M-추정법이다. M-추정법에서는 추정량이 명시적 형태로 주어지지 않으며, 특히 비볼록(non-convex)목적함수에서의 M-추정에 기존의 뉴튼 방법을 적용할 경우 목적함수의 대역최소점에서 해를 찾는데 실패할 위험이 있다. 본 논문에서는 이런 문제점을 유전자 알고리즘(genetic algorithm)을 이용하여 해결하고자 한다. 즉, M-추정에서 고려하는 목적함수를 미분하지 않고 목적함수 자체를 최적화(최소화)시키는 방법으로 해를 구하는 방안을 제시하고자 한다. 또한, M-추정에서 널리 쓰이는 뉴튼 방법에 의한 해의 문제점을 지적하고 제안된 방법에 의한 M-추정의 타당성을 예를 들어 보이고자 한다. The M-estimation is frequently considered as a robust procedure in the estimation of location parameter. Usually the M-estimator can not be represented as an explicit form. In this paper, we propose an M-estimation method in non-convex object function by using the genetic algorithm. The proposed method cirectly optimizes(minimizes)the object function without differentiating the function, and it approximates the global solution regardless of the initialization. An illustrative example shows that the proposed estimation method is stable and has elegant behavior, compared to the classical M-estimation.

This study is the results of experimental and numerical study on the consolidational behavior of multi-layered soft soil ground installed with plastic board drains (PBD). Centrifuge model tests with a marine clay sampled from field were performed to investigate the consolidational behavior of multi-layered ground where a dredged soil was placed on the soft clay ground and PBDs were installed. Test results were compared with those of numerical analyses, using the 2-D equivalent model previously proposed. From test resuts, it was found that the amount of consolidation settlement occurred in the original ground due to embankment surcharge loads was in the range of 38% of total settlement in the whole ground. From the results of cone penetration tests executed after finishing the centrifuge model tests, the cone resistance was found to increase with depth. The measured water contents inbetween PBDs were in the ranges of 38~50% and their values tended to increase with increasing the distance between PBDs.

Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.

feficotorfer fyf☞ri(Hp)가 위암파 관련이 있다는 역학적인 증거는 많이 있지만 이에 대한 정확한 기전에 대해선 밝혀져 있지 않고 있으며 실험동물 모델도 적절하지 못한 것으로 알려져있다. 본 실험에서는 위암의 원인으로 알려져 있는 f, fyforf'(Hp)를 이용하여 마우스에서 위암 모델을 확립하고 만성염증과정 중에 생성되는 리0와 COX-2 등의 발현이 위암발생에 미치는 명향을 통하여 예방과 치료를 위한 점근을 시도하고자 하였다. 마우스를 7군으로 나누어서 1, 2, 3, 4군의 등물은 MNU를 증류수에 200ppm 농도로 음수병득 이용하띤 10주간 격주로 투여하였으며 MHU 음술 투여 1주 휴씩 후 배양한 f. fyrofi 를 약 109cru/rfll 로 맞춰 한 마리당 0.1ml 씩 이틀 간격으로 세 번에 걸쳐 하룻방 금식시킨 1, 2, 3, 5, 6, 7군기 마우스의 위장에 투입하떴다. 균 투입을 마친 후 다응 날부터 2군쏙 6군은 iNOS 억제제인 aminoguanidine(AG)을 음수병으로 툰여하였으며 3군과 7군은 COX-2 척제제인 nimesulide(NSD)를 투여하였다. 위의 종양발생양상을 샅최보면 bfNU와 Hp만을 투여한 1 관 ; (hfNU +Hp), 2군 : iNO을 inhibitor 투여군(MNU+HP+AG'1. 3군 ;CO딘-2 Inilibitor 투여군(MNU누Hp누 NSD), 4군 ,MNlf 단독투여군, 5군 ;Hp 단독투여춘, 6군 ; 러p 단독에 AG투여군, 7군 , Hp 단독에 NSD투여군의 종양발샐을은 각각 쁜.Bff(l1/16), 70.6%f12/ti), 했.9ff(7/18), 10%(1/10), Off(O/IS)0%(O/S), 0%(O/5)의 발쟁율을 보여 iNOS 억제제인 AC은 좁양발생을 억계하지 못하였으며, COX-2억제제인 NSD 는 종양발생을 유의적으로 감소시켰다. 콩양발생개수에서는 2.62±0.36, 1.41츠0.14, 0.44 르0.12, 0.10±0.10을 보여 AC와 NSD에서 유의성 있게 발생개수를 줄였다.

It is, therefore, essential to have an appropriate animal model for detailed analysis of the role of H. pylori played in gastric carcinogenesis. There is a wealth of evidence to support that over production of inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2) is involved in the pathogensis of various cancer in both rodents and humans. The aim of this study was to establish a mouse model for H. pylori-associated gastric carcinogenesis and to identify the role of inducible nitric oxide synthase(iNOS) and cyclooxygenase-2(COX-2) played during the gastric carcinogenesis in mice. Eighty-three specific pathogen free, six-week-old male C57BL/6 mice were randomly divided into seven groups. Animals of the group 1, 2, 3, 4 were given MNU in their drinking water at the concentration of 200 p.p.m. for total five cycles of one-week regimen with one-week pause. After completion of MNU administration, they were given autoclaved distilled water for one weeks, and groups 1, 2, 3, 5, 6, 7 were inoculated with H. pylori. After completion of H. pylori. inoculation, groups 2 and 6 were given aminoguanidine in their drinking water at concentration of 1000p.p.m. and animals of group 3 and 7 were given the diet containing 200 ppm nimesulide at 12 weeks of age. All animals were killed at 50 weeks of age. The incidences of the glandular stomach tumors in the group 1, 2, 3 and 4 were 87.5%(14/16), 76.4%(13/17), 44.4(8/18), 10.0%(1/10), respectively and the tumor incidence of group 3(MNU→Hp+nimesulide) was significantly lower than those of group 1(MNU→Hp) at the value of P<0.01. The average numbers of tumors of group 2(MNU→Hp+AG : 1.41±0.24) and group 3(MNU→Hp+nimesulide : 0.44±0.12) were significantly lower than those of group 1(MNU→Hp : 2.62±0.36) at the value of P<0.05. Therefore, overproduced iNOS and COX-2 plays an important role in mice gastric carcinogenesis. We concluded iNOS and COX-2 inhibitor have good effects on gastric carcinogenesis.
