Lee, Chong-min (1994) Recursivenes, ambiguity, and sentence complexity. Linguistics, vol. 2. The purpose of this paper is to discuss the sentence complexity, focussing on the structrural recursiveness and ambiguity. When a person starts to understand the comprehension process of complex sentences, the two factors of recursion and ambiguity should be resolved for a fuller contextual information. Further, the principle of disambiguation is proposed to account for the technical strategies of complex sentences.

Propofol 마취와 Enflurane 마취간의 인지기능 및 정신운동기능의 회복에 관한 비교

박종민,이재민,김성년 대한마취과학회 1996 Korean Journal of Anesthesiology Vol.30 No.3

Backgrounds: For out-patient anesthesia a safe and rapid postoperative recovery, especially, the full recovery of psychological function for $quot;street fitness$quot; has become increasingly important. Up to the present, the scoring system - Steward postanesthesia recovery score - has been frequently used for the decision of discharge. But this system focuses on recovery of vital signs, other objective tests are needed to investigate cognitive and psychomotor function which is suitable for estimation of $quot;street fitness$quot;. Methods: The propofol group(n=70) received fentanyl 0.8 ㎍/kg followed by propofol I mg/kg for anesthesia induction. Continuous propofol infusion was initiated upon induction. Ventilation was supported with N₂O-O₂ mixture. The enflurane group(n=70) was induced with sodium thiopental 4 mg/kg. 2.0 vo1% of enflurane with N₂O-O₂ mixture was initiated immediately upon induction. Both group received vecuronium 0.08 mg/kg as muscle relaxants. We measured Steward postanesthesia recovery score as scoring sm and seven kinds of parameters as cognitive and psychomotor function test. The tests were performed at three measurement points; the day before the operation and 30, 60 minutes after extubation. Results: By the scoring system, no difference in recovery score at postop. 60 min. could be found between two groups. But by the cognitive and psychomotor function test, propofol group showed significantly better recovery than enflurane group at all tests, reaching control values at postop. 60 min. Conclusions: The scoring system is not suitable method for decision of discharge, thus cognitive and psychomotor function test should be performed for $quot;street fitness$quot; after outpatient anesthesia. Propofol was associated with less impairment in cognitive and psychomotor function than enflurane.

열처리에 따른 Cu 박막의 미세구조 및 전기 비저항의 변화를 조사하였다. Cu(hfac)(TMVS)를 원료로 하는 저압화학증착법에 의해 증착온도를 160℃에서 330℃까지 변화시키면서 TiN 기판 위에 Cu 박막을 제조하였고 450℃에서 30분간 열처리하였다. 증착온도에 따라 표면이 평평한 Cu 박막을 형성하는 표면 반응제한지역과 표면이 거친 Cu 박막을 형성하는 물질전달제한지역이 관찰되었다. 열처리 후 Cu 박막은 전체적으로 표면이 평탄해졌고 결정립의 크기는 모든 증착온도에서 증가하였는데 그 편차 역시 증가하여 EM 저항성 측면에서는 큰 효과를 보이지 못할 것으로 판단된다. 비저항은 증착온도 200℃에서 급격히 증가하였고 열처리 후에는 모든 증착온도에서 비저항이 감소하였는데 표면반응제한지역에서는 결정립 성장에 의한 약간의 비저항 감소를 보였으나 물질전달제한지역에서는 응집에 의해 Cu 결정립간의 전기적 연결 상태가 향상되어 급격한 비저항 감소를 보였다. The effects of the thermal annealing on the microstructure and the electrical resistivity of the copper films were studied. Copper film was prepared on TiN substrate by the low pressure chemical vapor deposition (LPCVD) using Cu(hfac)(TMVS) as the precursor at the deposition temperature between 160 and 330℃, and then annealed at 450℃ for 30 min. There were two distinct temperature regions, one is the surface reaction limited region, producing smooth surfaced copper film, and the other is the mass transport limited region which produces rough surfaced film. After annealing, the surfaces of the copper films had tendency to become smooth, and the grain size enlarged in all deposition temperature regions. However, the deviation of the grain size was increased too much to improve the EM resistance. The electrical resistivity showed a rapid increase at the deposition temperature of 200℃. After annealing, the resistivity of the copper film deposited in the surface reaction limited region decreased slightly by the grain growth, but ones deposited in the mass transport limited region decreased drastically by coalescence of the grains, causing the improvements of the electrical connections among copper grains.

수은(Hg)에 노출된 토마토 유모에 있어서 Ascorbic acid 산화에 대한 Anthocyanin의 항산화 기능

이종민,손희경,조운행 昌原大學校 基礎科學硏究所 1999 基礎科學硏究所論文集 Vol.11 No.-

토마토(Lycopersin esculentum) 유묘을 Hg에 노출시켰을 때 줄기와 잎에서 anthocyanin농도의 증가가 관찰되었으며, anthocyanin은 Hg에 의한 ascorbic acid의 산화를 억제하였다. 이러한 실험결과들은 anthocyanin의 Hg의 독성효과에 대항하여 Hg와 복합체를 형성하여 항산화제로서 중요한 역할을 할 수 있으며 ascorbic acid도 이러한 반응을 촉진시킬 수 있음을 보여준다. Mercury exposure caused an overall increase of anthocyanins in stems and leaves of tomato (Lycopersicon esculentum) seedlings. Furthermore, mercury increased the oxidation of ascorbic acid, and the oxidation reaction was suppressed by addition of anthocyanin. Our results suggest that anthocyanin not only chelates Hg ions, but also forms an ascorbic acid-metal-anthocyanin complex, which could be the possible protection mechanism from Hg-induced phytotoxicity.

메시지 프레이밍 효과에 대한 재고찰: 개인적 관여도와 상황적 관여도의 조절효과 비교를 중심으로

이종민 한국방송광고공사 2008 광고연구 Vol.0 No.78

This study aims to compare the direction of moderating effects of person-oriented enduring involvement versus situation-oriented(situational) involvement in the message framing contexts(gain vs. loss). This study argues that the directions of moderating effects of these two different types of involvement would be different. This difference is based upon the different role of enduring and situational involvement in information processing. Situational involvement plays a role of motivation and ability together in information processing while enduring involvement plays only a role of motivation. For testing the hypotheses, two experiments were conducted. The findings appeared to be consistent with our grand expectation that enduring involvement and situational involvement differently moderate message framing effects with respect of the directions. Yet the detailed findings revealed to be a little bit mixed or complicated. This study discussed intensively in these regards. 본 연구의 목적은 메시지 프레이밍에 미치는 개인적 관여도와 상황적 관여도의 조절효과를 비교하는 데에 있다. 본 연구는 개인적 관여도와 상황적 관여도가 일반 정보처리 과정에서 보여주는 상이한 역할에 근거하여, 이러한 차이가 메시지 프레이밍 상황에서도 상이한 조절효과를 보일 것이라 상정하고 있다. 부연하면, 일반적으로 상황적 관여도는 정보처리과정에서 동기와 능력의 역할을 동시에 수행하고 있는 반면에 개인적 관여도는 동기의 역할만을 수행하는 것으로 보고 있기 때문이다. 가설검증을 위해 두 차례의 실험이 실시되었다. 실험 결과는 전반적으로 본 연구가 상정했던 대로 두 관여도의 상이한 조절효과를 발견할 수 있었다. 하지만 세부적으로 볼 때 연구 결과가 다소 복잡하게 얽혀 있는 것으로 나타났다.

산딸나무 열매를 100% MeOH로 추출하고, 얻어진 추출물을 EtOAc, n-BuOH 및 물로 용매 분획 하였다. 이 중 EtOAc 분획으로부터 silica gel과 octadecyl silica gel(ODS) column chromatography를 반복하여 1종의 lignan 화합물을 분리, 정제하였다. 화합물의 화학구조는 NMR, Ms 및 IR 등의 스펙트럼 데이터를 해석하여, (+)-pinoresinol (1) 로 동정하였다. 이 화합물은 산딸나무에서 처음 분리되었다. LDL-항산화활성 억제활성이 20㎍/mL 처리농도에서 85.1±1.3%로 나타났다. (+)-Pinoresinol was isolated from the EtOAc fraction of methanol extracts of the fruits of Cornus kousa Burg. The chemical structures of (+)-pinoresinol was determined by spectroscopy method, as well as 1D- and 2D-NMR (^(1)H-^(1)H COSY, HSQC and HMBC) spectroscopy. This compound was the first to be isolated from C. kousa Burg. Also, (+)-pinoresinol inhibited LDL-oxidation with the inhibitory activity of 85.1±1.3% at a concentration of 20 ㎍/mL.

접촉각 측정에 의한 사이즈 분석

이찬용,김철환,최경민,박종열 경상대학교 농업생명과학연구원 2001 농업생명과학연구 Vol.35 No.-

접촉각(Contact Angle)이란 액체가 고체표면 위에서 열역학적으로 평형을 이룰 때 형성하는 각을 의미하며, 고체와 액체 사이에서 이루는 접촉각의 측정은 접착, 표면처리, 폴리머 표면 분석과 같은 많은 분야에서 잘 알려진 기술이다. 이러한 접촉각은 종이의 내수성에 대한 정밀한 예측을 가능하게 하는데 본 연구를 통하여 개발된 접촉각 자동 측정 시스템(AMS-2001)은 종이에 부여된 내수성을 종이 시료 상에 형성된 접촉각 측정을 통하여 정량화 할 수 있었다. 본 연구에서 개발한 AMS-2001을 이용하면 사이징 처리된 종이의 접촉각, 발수각, 액적의 폭, 지름, 표면장력 등을 측정할 수 있었고, 액적이 변화되는 모양을 디지털 화상을 통하여 추적할 수 있었으며 또한 기존의 Stockigt 실험 방법과 거의 유사한 재현성 및 신뢰성을 나타낼 수 있었다. The contact angle formed by a droplet of water used to estimate a repellency property of paper. The conventional systems measuring a contact angle are based on a manual measurement of the angle by a 3-point determination such as a far-left or far-right point, and a top point of a water droplet on a sample sheet. Thus the manual method to analyze a water repellency property can be greatly affected by an operator's bias. The new method to measure a sizing degree by a contact angle was developed using an automatic determination of 3-end point coordinates of the water droplet, which could diminish the operator's bias during measurement. The system could also quantify width and height of a water droplet, a surface tension of a solid specimen, and a time elapsed during complete absorption of water into a sheet. Finally, the values measured by the system were quite reproducible and reliable.

2-차원 IIR 디지탈 필터의 설계

이민호,박종연 江原大學校 産業技術硏究所 1994 産業技術硏究 Vol.14 No.-

This paper develops a design technique for approximating nonseparable frequency characteristics by sums and products of separable transfer functions. Therefore nonseparable frequency characteristics includes the four-quadrant symmetry filters. The desired filter with half plan symmetry is obtained by shifting a low pass characteristic in the frequency domain, and by combining these shifted characteristics. Also the paper develops the technique for designing recursive and nonrecursive two dimensional digital filters by the application of a complex transformation to one dimensional low pass filter.

비호지킨 림프종의 REAL 분류와 cyclin D1, bcl-2, p53및 bcl-6 단백발현

이미자,전호종,정종달,박유환,김민 조선대학교 2001 The Medical Journal of Chosun University Vol.26 No.1

Background and Objectives : There has been a continuous evolution of the lymphoma classification and recently a Revised European-American Lymphoma (REAL) classification was proposed by the International Lymphoma Study Group. This new classification requires information on immunophenotypic and molecular biologic markers in addition to the usual histologic findings. The distinction between mantle cell lymphoma (MCL) and other low grade B cell lymphomas is important because MCL has a more aggressive clinical course. The aim of this study is to determine the clinical characteristics and the relative frequency of malignant non-Hodgkin’s lymphomas (NHL) and analyze the expression of the cyclin D1, bcl-2, p53 and the bcl-6 protein. Materials and Methods : One hundred and twelve cases of NHL were recategorized by the newly described REAL classification categories and investigated for the expression of the cyclin D1, bcl-2, p53 and bcl-6 protein by the immunohistochemical method. Results : There were higher rates of extranodal lymphoma, diffuse large B cell lymphoma, and angiocentric lymphoma and lower rates of T cell lymphoma and follicular center lymphoma compared with Western countries. Cyclin D1 is expressed in all cases of MCL. But no cases except for MCL showed positive for cyclin D1. The expression of bcl-2 had decreased in high-grade lymphomas. Conclusion : It suggests that the cyclin D1 expression in mantle cell lymphoma could be reliably distinguished from its expression in other non-Hodgkin’ s lymphomas. In addition, bcl-2 may be useful for the differentiation of the low grade lymphoma from the high grade lymphoma.
