산과 영역에서 쌍태임신은 고위험임신으로서 조산, 높은 주산기 이환율 및 사망율과 모체에 여러 종류의 합병증을 초래하므로 산과적으로 쌍태 임신은 중요하여 지난 3년간의 쌍태 임산부 및 쌍태아에 대해 임상적 견지에서 조사하여 봤다. The thirty-nine twin deliveries at the Paik Hospital for 3 years front Jan. 1, 1977 to Dec. 31, 1979 were studied retrospectively. Twin delivers carries a considerable fetal & neonatal risk but the maternal mortality is not increased. 1.The frequency of twin delivery was one in 126 births. 2.The mean age was 28. The youngest was 20 years of age. The oldest was 35 years of age. 3.Primiparas were 22/39, 56.4% and multiparas were 17/39, 43.6%. 4.The mean durations of twin pregnancy was 38.9 weeks. 5.The diagnostic accuracy with physical examination & radiological examination before delivery of the twins was 92.3%. 6.The mean numbers of the antenatal care of twin pregnant woman was over 5. 7.The presentation; Head-Head 17/39, 43.6% Head-Breech 15/39, 38.4%. Breech-Breech 6/39, 25.4%. 8.The common maternal complication were anemia (69.23%). Toxemia (43.6%) post-partum Hemorrhage (38.5%). 9.The maternal morbiditiesy of postpartum women were hemorrhoids (12/39, 30.7%). G-I trouble (5/39, 12.8%) & wound abscess (5/39, 12.8%). 10.The methods of twin delivery were C/S (11/39, 28.2%) & vaginal deviveries (28/39, 71.8%). 11.The spontaneous vaginal delivery of placenta after twin birth was 25/28, 89.2% & manual delivery of placenta at vaginal twin birth was 3/28, 7.7%. 12.The mean duration of labor at vaginal delivery was 10 hour 30min 13.The mean interval of first & second birth at vaginal delivery was 5∼10min. 14.The mean birth weight of twin delivery was 2,408Gm. 15.The APGAR score at 1min. over 7 was shown in 32/38, 78.9% of the first twin & 23/38, 89.9% of the second twin. 16.There were both males 18/39, 46.15% & both females 13/39, 33.3% & opposite sex 8/39, 20.5%. 17.The placenta with monochorionic & diamnionic membrane were seen abou thalf of twin. 18.Fetal risk was defined in term of the increased rates of prematurity, stillbirth, & congenital anomalies (craniodidymus twin, cleftlip & palate, & fetal transfusion syndrom). 19.

박광웅,이강영,김치한,최상영,Park, Kwang-Woong,Lee, Kang-Yeong,Kim, Chi-Han,Choi, Sang-Young 한국국방경영분석학회 2007 한국국방경영분석학회지 Vol.33 No.1

본 연구의 목적은 비교항목들의 척도가 서로 상이하고 측정치를 산정하기 곤란한 대안들의 의사결정시 대안 비교를 과학적으로 할 수 있는 지식기반 대안분석모델(KAAM)을 제안하는 것이다. KAAM은 기존의 방법인 Saaty, Delphi/Shang, Consensus, SAW 기법을 근간으로 하는 하이브리드 방식으로 구성되고 엑셀기반으로 구현하였다. 또한, 무기체계 획득사업의 사전분석 단계에서 최적 획득방안을 선정하는 실증적 사례를 적용함으로서 KAAM의 유용성을 확인하였다. In the early stage of weapon system acquisition process, acquisition policy is necessarily established to acquire weapon system in a faster, better, cheaper way. Several alternatives, such as "buy", "domestic research and development", and "technical corporative production", can be considered for the best acquisition policy making. However, the comparison factors for those alternatives have different metrics and values. Therefore, the aim of this paper is to suggest KAAM(Knowledge-based Alternatives Analysis Model) as a scientific method to compare the alternatives having such different metrics and values and giving a weighted and normalized single measurement for the easy comparison. KAAM is a hybrid model incorporating Satty technique, Delphi/Shang method, Consensus method, and SAW method. KAAM is implemented on Microsoft Excel environment and provided tabular form user interface. Finally, an illustrative example is shown using KAAM.

朴光雄,趙陽子,徐仁銖 한양대학교 의과대학 1984 한양의대 학술지 Vol.4 No.1

In recent years the exotoxin of Pseudomonas aeruginosa infection have been observed as an important invasive factors of the toxic substances. So I prepared and isolated the exotoxin from the cultural filtrates of Pseudomonas aeruginosa PA-103 strain, and observed the biologic activity for crude exotoxin. Strain PA-103 was grown in a dialyzed medium of trypticase soy broth enriched with 1% glycerol and 1 M monosodium glutamate and then immediately after centrifugation, Zine acetate was added to the supernatant fluid. The mixture was left for a few hour and then centrifuged to collect the precipitate, which was dissolved in sodium citrate, and then obtained the crude PA-103 strain exotoxin. When mice lethal toxicity of pseudomonas aeruginosa PA-103 strains was inoculated into the peritoneal cavitty, LD? was 10? The supernatant fluid (18 hours) of this strain was showed the 40% low lethal rate on undiluted concentration but LD? of crude exotoxin was 44.54 ㎍. Immunization of rabbit with crude exotoxin resulted in the development of antitoxic serumm. This antitoxic serum was showed distinctly gel diffusion pattern with Ouchterlony method but precipitate values was low as 1 : 16. Skin responses of rabbit with the crude exotoxin was showed the reddish induration and necrosis etc. 1 Minimum Red Dose (MRD) was below 0.125 ㎍. Crude exotoxin of antitoxic neutralization in the skin responses of neutralization test in vitro neutralized the LD? as 1 : 16, and in vivo skin neutralization responses was slightly below than this.

The correlation hetween the serotypes an8 sea.sitivity distribution of Pseudomonas aeruginosa was studied w ith stoek itrains of departmeat, straias isolated from various clinical sources and strains of haspital environment of the yast two years. Two hundred and fi'fty seven strains wete typable and 38 strains were untypable out of 295 clinical sorces. Serotype B was aaoat prevalent (27.6%) followed by serotype G (24.9%), serotype E (23.3%) and serotype A (7.8%) ameng 257 typable strains. However, no serotype j,L and M were observed. Serotypie B,G,B aad A were isolated from pus, sputum, wound, burn site and urine. Seratypes E were most frequeatly isolated from hasal diecbarge aod serotypes K were isolated from pus. There were no apparent differences in sensitivity disttibution of streptomycin, carbenicillin and ampicillin between tbe clinical and The environmevtal origin. However, the strains of environmental origin were found to be relatively more susceptable to tetracycline, gentamicin and fradio- mycin than the strains of clinical sources in bigh concentration. Tbe strains of clinical sources of serotype B,G,E anl A showed different resistant patterns to all aotimicrobial agents except for carbenicillin. Serotype E showed the highest percentage resistance followed by serotype G.B and A.

이대옥,강태하,김학성,박광웅 한국군사과학기술학회 2001 한국군사과학기술학회지 Vol.4 No.2

In this paper, the nonlinear control of high precision pointing stabilization system using feedback-linearization design methodology based on system parameter identification is discussed. Modern nonlinear servomechanism theory is adapted to cope with the hard nonlinearities inherent in the turret system. The mathematical models of electrical turret driving system to develop a high performance control algorithm are derived, and the parameter estimation algorithm identifying the unknown system parameters such as vicious and coulomb frictions, stiffness and inertia is developed. Through computer simulation and experiments, it is shown that pointing and tracking accuracy and stabilization against the wideband stochastic disturbance induced by vehicle running on the bump course are improved. Therefore, it is considered the proposed nonlinear control technique is effective in counteracting the nonlinearities and disturbances.
