한국인에서 초음파유화흡입술을 이용한 백내장수술시 diclofenac sodium의 축동 방지효과
조희태,안영 동국대학교 경주대학 1997 東國論集 Vol.16 No.1
한국인과 같이 짙은 색을 띤 홍채에 초음파유화흡입술을 이용한 백내장수술시 Diclofenac sodium의 축동방지효과를 알아보고자, 40명의 백내장환자를 각 20명씩 2군(diclofenac치료군, 대조군)으로 나누어 double blind test로 본 연구를 시행하였다. 모든 대상 환자들은 백내장수술시 일상적으로 투약되는 약을 술전에 점안했고 치료군은 0.1% diclofenac sodium을 수술 2시간전부터 30분 간격으로 국소 점안하였다. 초음파유화흡입술로 백내장을 제고하고, 추방인공수정체를 삽입한 후 측정한 수술전 후의 동공 변화는 치료군은 -1.31±0.154㎜, 대조군에서 -2.51±0.232㎜로 diclofenac sodium투여군이 술후 축동이 작게 일어나는 것으로 나타났으며, 두 군 사이에 통계학적 유의성이 있었다(p=0.001). Forty patients undergoing elective phacoemulsification with intraocular lens insertion were divided in to a control group(n=20), treated group(n=20) in a double blind, prospective, randomized clinical study to evaluated the nonsteroidal, anti inflammatory drug, diclofenac sodium chloride as an aid for maintaining pupil dilatation during surgery in darkly pigmented iris like Korean. Both groups received the routine preoperative dilating drops and the treated group also received 0.1% topical diclofenac sodium chloride. After lens remove with phacoemulsifier and posterior chamber intraocular lens insertion, the change in pupil diameter from the preoperative measurement average -1.31±0.154㎜ in treated group and -2.51±0.232㎜ in the control group. The difference between groups was significant(p=0.001), favoring diclofenac sodium for maintaining pupil dilatation

Ganoderma lucidum 균주는 인공 배지 상에서 광에 의하여 자실체 원기가 형성되었으며, 광질이 자실체 원기 형성에 미치는 영향을 조사한 결과, 자실체 원기 형성능을 가지고 있는 5균주중 3균주는 공시한 모든 형광등의 아래에서 즉, BLB, 순청색, 순녹색, 순황색, 순적색 형광등의 아래에서 자실체 원기가 형성되었고, 2균주는 BLB 형광등을 제외한 가시광선 영역에서 형성되었다. 그러나 암상태에서는 공시한 모든 균주가 자실체를 형성하지 않았다. 자실체 원기는 광도 0.05에서 10.0 μmol m^-2 s^-1의 범위에서 형성되었고, 광도가 0.5 μmol m^-2 s^-1 이상에서는 자실체 원기의 수가 감소하였다. 주기적인 광조사가 자실체 원기의 형성에 미치는 영향을 조사한 결과, G1-009 균주는 자실체 원기의 수와 무게가 연속광을 조사한 경우보다 증가하였다. 자실체 원기를 형성하기 위해서는 최소 4일간의 광조사가 필요하였다. 단색광의 조사가 자실체 원기의 형성에 미치는 영향을 조사한 결과 G1-003 균주는 400에서 800 nm의 모든 단색광 처리구에서 자실체 원기가 형성되었고, 그 외의 4균주는 400에서 500 nm, 그리고 700에서 750 nm 범위에서 형성되었다. The objective of this research was to determine the effect of light quality on formation of fruit body primordia (FBPs) of Ganoderma lucidum. To achieve this 5 isolates of the fungus that develops fruit body primordia on nutrient agar media were incubated with or without continuous irradiation. The fluorescent lamps used different colors such as black light blue (BLB), pure blue (P-B), pure green (P-G), pure yellow (P-Y) and pure red (P-R). Effect of periodic light and dark exposures on FBP formation of isolate G1-009 was investigated. The FBP formation in G. lucidum isolates was also tested under nomochromatic light produced by the combination of interference filters and colored glass filters. Three isolates produced FBPs under all kinds of fluorescent lamps, whereas two induced FBPs only under visible light except for BLB fluorescent lamp. However, these isolated did not form FBPs in the dark. The FBP was formed at light intensity from 0.05 to 10.0 μmol m^-2 s^-1, and begun to reduce its number as light intensity increase over 0.5 μmol m^-2 s^-1. When the isolate was incubated under periodic light and dark exposures, the number and weight of FBP increased as compared with those under continuous light. Initiation of FBP requires at least 4 days of light illumination. Although isolate G1-003 produced FBPs in a wide range of 400 to 800 nm, other four isolates had two effective regions 400 to 500 nm and 700 to 750 nm in FBP formation.

We present a search for the standard model Higgs boson in 9.5 fb<SUP>-1</SUP> of pp@? collisions at s=1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. The final state considered contains a pair of b jets and is characterized by an imbalance in transverse energy, as expected from pp@?→ZH→νν@?bb@? production. The search is also sensitive to the WH→@?νbb@? channel when the charged lepton is not identified. The data are found to be in good agreement with the expected background. For a Higgs boson mass of 125 GeV, we set a limit at the 95% C.L. on the cross section σ(pp@?→[Z/W]H), assuming standard model branching fractions, that is a factor of 4.3 times larger than the theoretical standard model value, while the expected factor is 3.9. The search is also used to measure a combined WZ and ZZ production cross section that is a factor of 0.94+/-0.31(stat)+/-0.34(syst) times the standard model prediction of 4.4 pb, with an observed significance of 2.0 standard deviations.

Loan consultants assist clients with loan application processing and loan decisions. Their duties may include contacting people to ask if they want a loan, meeting with loan applicants and explaining different loan options. We studied the efficiency of service quality of loan consultants contracted to a bank in Korea. They do not work as a team, but do work independently. Since he/she is not an employee of the bank, the consultant is paid solely in proportion to how much he/she sell loans. In this study, a consultant is considered as a decision making unit (DMU) in the DEA (Data Envelopment Analysis) model. We use a principal component analysis-data envelopment analysis (PCA-DEA) model integrated with Shannon’s Entropy to evaluate quality efficiency of the consultants. We adopt a three-stage process to calculate the efficiency of service quality of the consultants. In the first stage, we use PCA to obtain 6 synthetic indicators, including 4 input indicators and 2 output indicators, from survey results in which questionnaire items are constructed on the basis of SERVQUAL model. In the second stage, 3 DEA models allowing negative values are used to calculate the relative efficiency of each DMU. In the third stage, the weight of each result is calculated on the basis of Shannon’s Entropy theory, and then we generate a comprehensive efficiency score using it. An example illustrates the proposed process of evaluating the relative quality efficiency of the loan consultants and how to use the efficiency to improve the service quality of the consultants.
초기 코드백터 결정에 의한 LBG 알고리즘의 성능 개선
홍지훈,조제황,Hong, Chi-Hwun,Ch0, Che-Hwang 한국음향학회 1995 韓國音響學會誌 Vol.14 No.2
Choosing initial codevectors in the LBG algorithm controls the performance of a codebook, because it only guarantees a locally optimal codebook. In this paper, we propose the decision method of initial codevectors by a decision radius which takes for feature vectors DC, low frequency, medium frequency and high frequency terms generated by a DCT. The more the decision radius is increased in order to decide initial codevectors, the more the number of membership vectors and the standard deviation for distance among the initial codevectors are increased. To obtain improved performance for a codebook, the decision radius for DC term is required above 0.9 of the membership rate and those for low frequency, medium frequency and high frequency terms under 0.6 of it. LBG 알고리즘은 국소적 최적 코드북 만을 보장하기 때문에 초기 코드벡터의 결정이 코드북의 성능을 결정한다. 본 논문에서는 초기 코드벡터의 결정에 있어서 이산여현변환 후에 발생되는 DC 항, 저주파 항, 중간주파 항, 그리고 고주파 항을 특징벡터로 하여 결정반지름에 의한 초기 코드벡터 결정 방법을 제안한다. 결정반지름이 증가함에 따라 소속되는 벡터수와 초기 코드벡터의 거리 표준편차가 증가함을 알 수 있다. 초기 코드백터의 결정에 있어서 DC 항은 $128\times128$ 영상과 $256\times256$ 영상의 모든 경우에 있어서 소속률이 0.9 이상인 결정반지름을 선택하고, 저주파 항, 중간주파 항, 그리고 고주파 항은 소속률이 약 0.6 이하의 결정반지름을 선택할 때 보다 우수한 성능의 코드북을 얻을 수 있다.

<P>We present a measurement of the correlation between the spins of t and (t) over bar quarks produced in proton-antiproton collisions at the Tevatron Collider at a center-of-mass energy of 1.96 TeV. We apply a matrix element technique to dilepton and single-lepton+jets final states in data accumulated with the DO detector that correspond to an integrated luminosity of 9.7 fb(-1). The measured value of the correlation coefficient in the off-diagonal basis, O-off = 0.89 +/- 0.22 (stat + syst), is in agreement with the standard model prediction, and represents evidence for a top-antitop quark spin correlation difference from zero at a level of 4.2 standard deviations.
