육근영,양규호,최남기,김선미 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.2

전치부 개교는 중심 교합시 수직선상에서 상하악 전치간에 교합이 되지 않는 상태이며, 부정교합의 특성과 원인이 치료계획에 중요한 역할을 한다. 혼합 치열기에 전치부 개교의 치료 목적은 악습관을 조절하고 입 주위 근육의 비정상적인 기능을 제거하며, 악정형 장치를 통해 하악의 수직성장을 수평성장으로 전환하는 것이며, 치료 후의 안정성을 위해 계속적인 관찰이 필요하다. 본 증례에서는 혀내밀기 습관이 동반된 전치부 개교 환아의 치료를 위해 습관을 차단하는 tongue crib과 그 밖에 다양한 가철성 및 고정성 장치를 사용하여 양호한 결과를 얻었기에 보고하는 바이다. Anterior open bite is defined as the lack of contacts between the functional occluding teeth on vertical line at centric occlusion and classified into functional and skeletal anterior open bite based on its causes and characteristics. In mixed dentition, habit control and the elimination of abnormal perioral muscle function and moving the vertical direction development to the sagittal direction of the mandible by the functional appliance is a goal of treatment. This study presents the effective interception of oral habit by the tongue crib and functional-fixed treatment and treatment response of open bite related to tongue thrust habit.

We studied the native defects of dilute magnetic semiconductors Zn₁-xFexSe epilayer by using SAW device. The energy gap of Zn₁-xFexSe for each epilayer(x=0.0213, 0.0915) was 2.57eV, 2.74eV at room temperature (294K). The trap level for x=0.0213, 0.0915 were calculated by measuring Transverse Acoustoelectric Voltage(TAV). Also we can calculated cross section.

영어 등위구조에서의 추출 현상

이남근,정수영 조선대학교 인문학연구소 1998 外國文化硏究 Vol.21 No.1

등위구문은 피접속요소가 서로 대등한 문법적 관계로 접속되는 구조로서 모든 언어에 산재하는 현상으로 많은 언어이론의 연구대상이 되어왔다. 그러나 등위구문을 분석함에 있어서 어떠한 시각에서 접근할 것인가에 대해 견해는 아주 다양하다. 현대 통사론에서 등위구문은 매우 중요한 문제로 다루어져 왔으며 가장 논란이 많은 문제 중의 하나일 것이다. 통사적인 제약이 가해져서 추출이 이루어진다고 판단하는 견해와 의미론적인 또는 화용론적인 관념들이 적용되어서 등위구문에서의 추출이 이루어진다는 견해등이 있다. Ross(1967)가 등위구조제약과 같은 조건을 제시한 이후로 지금껏 많은 학자들이 영어의 등위구조에서의 추출현상을 여러 각도에서 연구를 거듭하여 왔다. 그중에는 등위구조에서의 추출을 의미론적인 면과 화용론적인 면에서 접근하는 학자들이 많이 있다. 이 논문에서는 Lakoff(1986)나 Goldsmith(1985)와 같은 학자들의 의미론적인 입장과 Schmerling(1976)의 화용론적인 입장에서 영어에서의 등위구조의 추출현상을 다룬다. 영어의 등위구문에서의 추출 현상을 본석함에 있어서 이 세가지 측면에서의 분석을 논의하고 각각의 문제점을 제시하고자 한다. Coordinate structures consist of more than two conjuncts. Ross suggested that a conjunct cannot be moved and any element in a conjunct cannot be extracted from that conjunct. The first part of the Coordinate Structure Constraint, the Conjunct Constraint, prevents extraction of a whole conjunct, and the second part, the Element Constraint, prohibits extraction of any element in a conjunct. But not all languages follow that constraint. Ross admitted there is an exception : extraction out of conjuncts is possible only if the extraction is Across The Board. That is, the extraction out of coordinate structures is well-formed only if elements are extraction out of coordinate structures is well-formed only if elements are extracted out of all conjuncts. Violations of the Element Constraint are allowed just in case the ATB condition is met. But not all sentences follow the Coordinate Structure Constraint, the exception of that constraint being Ross's Across The Board. Thus, the fundamental problem is raised of whether the coordinate structure constraint really exists. On this, Goldsmith and Lakoff suggested that the extraction from the coordinate structure can be justified if coordinate sentences are related with some sort of semantic or pragmatic conditions instead of syntactic constraints. It is accepted that coordinate sentences have something to do with some semantic or pragmatic presuppositions like sequentiality.

최영근,최옥,김건남,박은석,지상철 한국약제학회 2003 Journal of Pharmaceutical Investigation Vol.33 No.2

In order to evaluate the effects of vehicles and penetration enhancers on skin permeation of apomorphine, the skin permeation rates of apomorphine from vehicles of different composition were determined using Franz diffusion cells fitted with excised rat skins. Solubility of apomorphine in various solvents was investigated to select a vehicle suitable for the percutaneous absorption of apomorphine. The solvents used were propylene glycol (PG), Transcutol^??, Labrasol^??, Labrafac hydro WL^??, Labrafil WL 2609 BS^?? and isopropyl alcohol. Even though permeation rates of apomorphine from each vehicle were low (0.08-0.36㎍/㎠/hr), the combination of PG and Labrafac^?? increased it significantly. The permeation rates of apomophine from PG/Labrafac^?? mixtures increased as the volume fraction of PG in the mixture increased. The maximum permeation rate of 18㎍/㎠/hr was achieved at 30% of PG, which decreased with further increase of PG fraction. A series of fatty acids, alcohols and monoterpenes were employed as penetration enhancers. Incorporation of each enhancer in the PG/Labrafac^?? (30:70) mixture at the level of 10% improved the skin permeation significantly. The highest permeation rate, 117㎍/㎠/hr, was attained with myristic acid.

이수미,김영탁,정동근,남주현,목정은 울산대학교 의과대학 1992 울산의대학술지 Vol.1 No.1

The purpose of our study was to evaluate whether the combined use of serum tumor markers, CA 15-3 and TAG 72 could improve the efficacy for discriminating malignant from benign ovarian masses in patients with elevated serum CA 125 levels. Serum CA 15-3 and TAG 72 were preoperatively measured by immunoradiometric assay in 78 patients with pelvic masses who had elevated serum CA 125 levels above 35 U/ml. In 32 patients with epithelial ovarian cancers, serum CA 125 levels were elevated above 65 U/ml in 97% and serum CA 15-3(>30U/ml) and TAG 72(>10 u/ml) levels were elevated in 59% and 50%, respectively, suggesting relatively low sensitivity of CA 15-3 and TAG 72. However, in 41 patients with benign ovarian tumors, elevations of these two markers were detected only in 7% and 5%, respectively, and particularly, both markers were not elevated among all the aptients over 50 years of age. Coordinate elevations of CA 125(>35U/ml) and CA 15-3(>30U/ml) or TAG 72(>10 U/ml) could discriminate epithelial ovarian cancers from benign masses with a sensitivity of 72% and specificity of 90%. Among patients over 50 years of age, sensitivity and specificity were increased to 79% and 100%, respectively. It is concluded that the combined use of CA 15-3 and TAG 72 with CA 125 could obtain an improved efficacy for discrimination of epithelial ovarian cancer, especially among patients over 50 years of age.

산성 불소가 복합레진 표면에 미치는 영향

양규호,육근영,최남기,김선미 대한소아치과학회 2007 大韓小兒齒科學會誌 Vol.34 No.2

복합레진 수복은 치아우식 및 치아우식 예방치료를 위한 대표적인 술식으로 소아치과 영역에서 널리 시행되고 있으며 불소도포는 치아우식 예방을 위한 대표적인 술식으로 1년에 2번 정도 실시되고 있다. 하지만 이러한 이점에도 불구하고 Acidulated phosphate fluoride(APF)가 복합 레진의 표면을 거칠게 한다는 부작용에 대한 논란이 있다. 이에 본 연구에서는 불소도포가 복합레진의 표면에 미치는 영향을 평가하기 위해 시판용 레진인 Solitaire 2^(®)(Heraeus Kulzer, Germany), Metafil CX^(®)(Sun medical, Japan), Composan LCM^(®)(Promedica, Germany), Charmseal^(®)(DenKist, Korea)을 이용하여 시편을 제작하고, 불소젤은 Topex^(®)(Sultan Dental Products, Canada)를 각각 1분과 4분동안 도포시킨 후 변화를 관찰하여 다음과 같은 결과를 얻었다. 1. 불소젤을 도포시키지 않은 대조군에서 가장 평활한 표면을 보였으며 1분군, 4분군 순으로 표면 거칠기가 증가하였다. 그리고 Composan LCM^(®)을 제외한 모든 제품에서 유의한 차이를 보였다(p<0.05). 2. 국소도포용 불소젤을 도포한 각 레진 시편의 무게 차이를 비교한 결과 대조군, 1분군, 4분군 간에 유의한 차이는 없었다(p>0.05). 3. 주사전자현미경 관찰시 불소젤을 도포시킨 실험군은 대조군에 비해 거친 표면을 나타내었다. Composite resin restorations are widely used to restore decayed teeth or preventive restoration in children. Children often receive topical fluoride treatments on a semiannual basis. However there is concern that topical acidulated phosphate fluorides (APF) may cause deterioration of composite resins. The aim of this study was to evaluate the surface changes in composite resins due to topical fluoride application. Composite resins(Solitaire 2^(®), Metafil CX^(®), Composan LCM^(®), Charmseal^(®)) in topical fluoride agents were immersed and their surface roughness, weight loss and SEM findings were evaluated. The results were as follows: 1. The 4 minutes-immersion group showed more roughened surface than 1 minute-immersion group and the control group showed the smoothest surface among all the materials, and there was statistically significant difference between the groups except the Composan LCM^(®)(P<0.05). 2. There was no significant difference between the 1 minute-immersion group and 4 minutes-immersion group in weight loss (P>0.05). 3. The experimental group treated with topical fluoride gel showed generally more roughened surface than control group in the SEM findings.

선형유도전자펌프내의 자기유체 유동에 관한 수치적 연구

최훈기,유근종,박태봉,은재정,장남영 국립7개대학공동논문집간행위원회 2003 공업기술연구 Vol.3 No.-

Numerical analysis is performed for magnetic and MHD flow fields in Electro-Magnetic(EM) pump. A finite volume method is applied to solve magnetic field governing equations and the Navier-Stokes equations. Vector and scalar potential methods are adopted to obtain the electric and magnetic fields and the resulting Lorentz force in solving Maxwell equations. The magnetic field and velocity distributions are found to be influenced by the magnitude of the Reynolds number and the phase of applied electric current. Computational results indicate that the magnetic flux distribution with changing phase of electric current is characterized by a pair of counter-rotating closed loops. The velocity distribution of the flow field is influenced on the intensity of Lorentz force.
