確率有限要素法을 利用한 Frame 構造物의 信賴性解析

신재철,정원석,한성호,김선훈 忠南大學校 産業技術硏究所 2002 산업기술연구논문집 Vol.17 No.1

In this paper reliability analysis using stochastic finite element method is formulated, and with its result reliability analysis is accomplished. A displacement and member force of frame structure is acquired in SFEMP(Stochastic Finite Element Method Program) using perturbation method, and then DMCSP(Direct Monte Carlo Simulation Program) is used to verify and compare previous results. With the previous two results, approximate reliability analyses of the MFOSM(Mean First Order Second Moment), AFOSM(Advanced First Order Second Moment), and MCS(Monte Carlo Simulation) including a relatively simple limit state function have accomplished and base of a safety estimate could be acquired. Finally, When the reliability analysis of a complicated structure using stochastic finite element method is accomplished, time is efficiently reduced, and the safety of a structure can be easily evaluated. Hence SFEMP may be considered an efficient tool for evaluating the structural safety and reliability of frame structure.

이중 셀 구성에 의한 셀룰라 이동통신 시스템의 채널용량 개선

신창윤,우병훈,조성준 한국항공대학교 1994 論文集 Vol.32 No.-

본 논문에서는 셀에서의 용량 증대를 위하여 셀을 내부 셀과 외부 셀로 나누어 구성하는 이중셀을 적용하였을 경우 반송파 대 동일채널간섭비와 채널용량을 산출하고 분석하였다. 이를 위하여 셀룰라 육상이동통신 시트테에서 규칙적인 주파수재사용 패턴 N을 도출하여 무지향성 안테나 사용시와 지향성 안테나 사용시 셀 패턴에 따른 반송파 대 동일채널간섭비를 계산하였다. 이중 셀을 구성하였을 때 내부 셀에 주파수 재사용 패턴 N을 작게하여 내부와 외부 셀의 주파수 재사용 패턴을 다르게 하면 채널용량이 크게 개선되었다. 실제적인 통화품질 기준인 반송파 대 동일채널간섭비가 24dB 이상이 되는 경우 가장 용량면에서 우수한 주파수 재사용 패턴은 N=7인 3 섹터 셀이었고 이중 셀로 구성하였을 경우 내부 셀 패턴이 N=3, 외부 셀 패턴이 N=7인 3 섹터 셀의 경우였다. 이 경우 이중 셀을 구성하지 않은 N=5인 주파수 재사용 패턴과 같은 용량을 가질 수 있었다. 이것은 이중 셀을 상용하므로서 한정된 주파수의 수용 용량을 1.4배 높일 수 있음을 알 수 있다. In this paper, when the dual cell, a cell which is divided into the inner cell and outer cell, is employed to increase the channel capacity, the carrier power to co-channel interference power ratio (C/I) and channel capacity are evaluated and analyzed. For this evaluation, the regular frequency reuse pattern factor N is calculated and them the C/I is calculated according to the cell pattern when the isotropic antenna is used and the directional antenna is used, respectively. In a dual cell, the channel capacity is incrased by making the frequency reuse pattern factor N of inner cell smaller than that of outer cell. In the case of nondual cell, the channel capacity is the largest when the frequency reuse pattern factor N is 7 in the 3 sector cell on the condition of the C/I is over the 24dB of standard call quality. In the case of dual cell, the channel capacity is the largest when the frequency reuse pattern facotr N is 3 for inner cell and N is 7 for outer cell. In this case, the cell has the same capacity as the frequency reuse pattern factor N=5 of nondual cell. This result shows that the channel capacity with dual cell can be incrased in the limited available frequency by 1.4 times more than the capacity with nondual cell.

본 연구는 탄산가스화법에 의한 탄산칼슘 입자 제조 공정에 있어서, 탄산가스로 채워진 반응기에 수산화칼슘 슬러리를 분사하는 방법으로 탄산칼슘 입자를 제조하였다. 수산화 칼슘의 농도(0.25~1.0wt%), 분사압력(0.5kgf /㎠~1.5kgf /㎠) 및 반응기 온도(20℃, 28℃)의 변화에 따른 생성된 탄산칼슘을 관찰하였다. 수산화 칼슘의 농도가 비교적 높으면(0.75wt%, 1.0wt%), 생성물의 pH와 전도도는 높게 나타났다. 분사압력에 의한 탄산칼슘 제조의 변화는 분사압력이 높아질수록(1.5kgf /㎠), pH와 전도도는 높게 측정되었다. 그러나, 수산화 칼슘의 농도와 분사압력의 변화가 탄산칼슘의 입자크기, 형태, 결정구조에 영향을 미치지는 않았다. 반응기의 온도가 28℃에서 생성된 탄산칼슘은 1.0㎛이하의 칼사이트 상 입자가 제조되었으며, 20℃에서 생성된 탄산칼슘은 0.5㎛이하의 칼사이트 상 입자가 제조되었다. 반응기의 온도가 낮아질수록 탄산칼슘 입자의 크기가 작아짐을 알 수 있었다. For the preparation of calcium carbonate particles from aqueous Ca(OH)2 slurry, carbonation reaction of aqueous Ca(OH)2 slurry was carried out by spouting the aqueous slurry of Ca(OH)2 into reactor filled with CO2 gas. The concentration of Ca(OH)2 varies from 0.25wt% to 1.0wt%, nozzle pressure from 0.5kgf /㎠ to 1.5kgf /㎠, and reactor temperature were set at 20℃ and 28℃. With relatively high concentration of 0.75wt% and 1.0wt% of Ca(OH)2, pH and conductivity of product-stream were observed high value. High pH and conductivity were observed at high nozzle pressure of 1.5kgf /㎠. The concentration of Ca(OH)2 and nozzle pressure, however, did not change the particle size and shape of calcium carbonate synthesized by carbonation reaction. The reaction temperature affected particle size. At reactor temperatures of 28℃ and 20℃, the particle sizes were about 1.0㎛ and 0.5㎛, respectively. Crystal structure of calcium calcium carbonate was of calcite. When reactor temperature was lower, the size of calcium carbonate particle was smaller.

성일용,류성호,신상훈,김욱규,김종렬,정인교,변기정 大韓顎顔面成形再建外科學會 2003 Maxillofacial Plastic Reconstructive Surgery Vol.25 No.1

The authors analyzed retrospectively the 60 patients with ameloblastoma who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from MArch, 1990 to December, 1995. The results obtained were as follows: There were 26 males (43.3%) and 34 females (56.7%). The peak age of patients was the third decade (41.7%). The majority of cases occurred in the mandible 93.3%, especially in the angle region (91.1%). Eighteen of 60 patients (30.0%) were associated with an impacted tooth, by impacted 3rd molar teeth (16.6%), molar (10.0%), and premolar and canine (3.4%) in order., Fifteen of 60 patients (25%) were associated with an odontogenic cyst, by dentigenous cyst(13.3%), odontogenic keratocyst(8.4%), and radicular cyst(3.3%) in order. Radiographically, there were 32 unilocular types(54.2%) with average age of 24.9±10.8 years, 14 multilocular types(23.7%) with average age of 35.7±17.7 and 13 mixed types(22.0%) with average age of 41.4±15.8. Histopathologically, there were 42 follicular types(70.0%) with average age of 33.7±15.1 years and 18 plexiform types(30.0%) with average age of 26±14.6. Conservertive treatment was performed in the 33 patients(55.0%) and their average age was 25.2±13.9 years and radical treatment in the 27 patients(45.0%) and their average age was 39.3±41.8. Overall recurrence rate was 10%. A consistent correlation between the age of the patient and the radiographic or histologic type of mandibular ameloblastoma was observed. There was a tendency for ameloblastomas of the follicular type to show a multilocular or mixed appearance and for those of the plexiform type to show a unilocular appearance.
