The purposes of this study were to classify the anteroposterior and vertical skeletal pattern of normal occlusion samples into specific types with factor and hierarchical cluster analysis, and to evaluate the range and limit of skeletal relationships that permit the establishment of normal occlusion via natural dentoalveolar compensation. Lateral cephalograms of 294 normal occlusion samples were measured, as selected from 15,836 persons through a community dental health survey who cooperated in record taking. Using a factor analysis, two factors representing anteroposterior and vertical skeletal relationships were extracted from 18 skeletal measurements. Then cluster analysis classified the skeletal patterns into nine types. The means and the standard deviations of 8 anteroposterior skeletal measurements and 10 vertical skeletal measurements were determined and comparisons of these measurements among the types were performed. The results obtained in this study showed that the range of normal occlusion included very diverse anteroposterior and vertical skeletal relationships.

ZnO는 직접 천이형 반도체로써, 상온에서 3.4eV에 해당하는 띠틈을 가지고 있다. 뿐만 아니라 60meV의 큰 엑시톤 결합에너지를 가지고 있어 단파장 광전 소자 영역의 LED(Light Emitting Diode)나 LD(Laser Diode)에 널리 사용되고 있다. 하지만 일반적으로 격자틈새 Zn(Zni2+)이온이나 O 빈자리(V02+)이온과 같은 자연적인 도너 이온이 존재하여 n-형 전도성을 나타낸다. 그러므로 ZnO계 LED와 LD의 개발에 있어서 가장 중요한 연구 과제는 재현성 있고 안정된 고농도의 p-형 ZnO박막을 성장시키는 것이다. 하지만, 자기보상효과나 얕은 억셉터 준위, 억셉터의 낮은 용해도로 인하여 어려움을 가지고 있다. 본 연구에서는 고품질의 p-형 ZnO박막을 제작하기 위해 AlN를 도핑시킨 ZnO박막을 RF 마그네트론 스퍼터링 법을 이용하여 Ar과 O2분위기에서 성장시켰다. ZnO와 AlN타겟을 동시에 사용하였으며, ZnO타겟에 걸어준 RF 파워는 80W, AlN타겟에 걸어준 RF 파워는 5~20W로 변화시켰다. 박막의 전기적, 광학적 특성은 XPS (X-ray Photoelectron Spectroscopy), REELS (Reflection Electron Energy Loss Spectroscopy), XRD (X-ray Diffraction), SIMS (Secondary Ion Mass Spectrometry), AES (Auger Electron Spectroscopy), Hall measurement를 이용하여 연구하였다. XPS측정결과, AlN를 도핑시킨 ZnO박막의 Zn2p3/2와 O1s피크는 undoped ZnO박막의 피크보다 낮은 결합에너지에서 측정되었다. 모든 박막이 결정화 되었으며, (002)방향으로 우선적으로 성장된 것을 확인할 수 있었다. 홀 측정 결과, 기판을 $200^{\circ}C$로 가열하면서 성장시킨 박막이 p-형을 나타내었으며, 비저항(Resistivity)이 $5.51{\times}10^{-3}{\Omega}{\cdot}m$, 캐리어 농도(Carrier Concentration)가 $1.96{\times}1018cm^{-3}$, 이동도(Mobility)가 $481cm^2$/Vs이었다. 또한 QUEELS -Simulation에 의한 광학적 특성분석 결과, 가시광선영역에서 투과율이 90%이상으로 투명전자소자로의 응용이 가능하다는 것을 보여주었다.

The objective of this study was to investigate the effect of undergraduates' self-directed learning on the school life satisfaction and interpersonal relation ability. For this purpose, 341 undergraduates were targeted and analyzed. The results of the study are as follows. First, as a result of analyzing school life satisfaction, a sub-factor of self-directed learning, all of gender, grade, and age affected. In addition, sub-factors such as study confidence, study passion, study responsibility seemed to affect positively significantly in order. Second, as a result of analyzing the effect on interpersonal relation skills of self-directed study, there was no significant relation in gender, grade, and age. Based on the results of this study, it was confirmed that school life satisfaction and interpersonal relation abilities are closely related to self-directed learning. This is significant in that to revitalize institutions such as educational service, study support for students, self-directed learning programs development in education field at the university, etc. are required.

Fuel oil mostly used for a ship is made from crude oil by refining process. In order to produce plenty of high-quality fuel oil, the Fluid catalytic cracking(FCC) method is widely adopted to many refinery factories during the decomposition process from high molecule into lower molecule. The major constituents in spent FCC catalysts are Si, Al, Fe, Ti, alkali metals and some others. The spent catalyst is also composed small amounts of rare metals such as Ce, Nd, Ni and V. The big problem in FCC oil is mixing the catalyst in the oil. This reason is unstable separation of FCC catalyst in separator. Such a FCC catalyst will become a reason of heavy wear down in moving parts of engine. The impurity in oil is ash and deposit compound, such as Al, Si, Ni, Fe and V, which will accelerate the wear down on fuel pump, fuel injection valve cylinder liner and piston ring. It is important to find a basic reason of an engine trouble for preventing similar troubles anymore. Insurance compensation will be different according to the reason of an engine trouble which might be natural abrasion or other external causes. In this study, types and reasons of engine troubles related to fuel oil will be covered.

The purpose of this paper is to elucidate the characteristics that make Guillermo del Toro's film Pan's Labyrinth (2006) a fantasy film, and the meaning and function of the labyrinth motifs closely related to it. Tzvetan Todorov defined the 'fantastic' as the hesitation between natural and supernatural interpretations in the face of supernatural events that invade reality. In Pan's Labyrinth, the fantastic continues to be seen, because the film does not allow the hesitation to disappear; thus, the fantastic does not enter the 'uncanny' genre or 'marvelous' genre, and because it keeps its fantastic state. In this case, the labyrinth symbolizes art as a passage into the fantastic world and a space that represents it. Rosemary Jackson saw the fantasy as a "literature of desire to compensate for a lack resulting from cultural constraints" and thus repeatedly dealing with unconscious materials. Del Toro's film shows the character of the fantastic as an expression of desire by allowing 'family romance' to take place in the fantastic world. In this case, the labyrinth symbolizes the mind as a place of desire. Kathryn Hume defined fantasy as a reaction to reality, like mimesis, and 'departure from consensus reality.' The film, operating in a 'vision' genre, satisfies its definition by allowing the fantastic world to illuminate the reality world through 'contrastive' technique, and brings out the fantastic it has. In this case, the labyrinth symbolizes the world as a mirror of the world of reality. Thus, Pan's Labyrinth is representative of fantastic film in that the fantastic functions very effectively, and the labyrinth appearing in this film can be evaluated as a motif that is full of meaning by symbolizing all three elements of art, world and mind. The significance of this paper is to shed light on how a motif works in a particular genre through the above considerations.
