This study aims to explore the creation of fashion design that embraces the diversity of human culture by examining oriental images that appear in the modern fashion with a focus on new paradigms that significantly affect human life as the latest trends, and by reflecting the trends of the times. The results of this study are as follows: First, this study examined that with regard to paradigm, a theoretical frame to view universe, the dichotomous, determinist, mechanism, linear paradigm collapsed to convert to undetermined, exoteric, pluralistic, indeterministic, organic, and holistic paradigm. The new paradigm is identified to have emerged before and after 1950s, and through the new paradigm, the characteristics of postmodernism such as historicality, popularity, locality, folkways and the characteristics of deconstructionism, internally mutual text, post phenomenon, undeterminability and externally exposure, destruction, poverty, decomposition and analysis, were identified. Second, the Orient is defined as the generic term referring to the entire Asian areas east of Turkey. Through the developmental process of oriental images, it was converted from the Oriental image, which mysteriously and romantically represents oriental elements, into the ethnic image that represents long time oriental traditions and indigenous culture together with the characteristics of the new paradigm. Third, the artistic characteristics of the Oriental costumes presented by Korea, China and Japan are expressed in developmental types, T-type plane structure, layered style, asymmetrical adjustment and easy silhouette, and they show indigenous characteristics of each country, for example, Chinese styles in dragon pattern, red and yellow, Japanese styles in flower design and achromatic color. Fourth, the Oriental Image, combined with the postmodernism and deconstructionism through the new paradigm, has two: one Oriental image highlights traditional elements by creating new Oriental image such as natural image, folk image, hybrid image and deconstruction image; and another is undetermined and vague by combining or decomposing Oriental or Western elements. It is expected that fashion designs that reflect these contexts of the times will contribute to the strengthening of international competitiveness.

The retraction of anterior teeth is one of the fundamental methods in orthodontic treatment and a proper position and angulation of anterior teeth after the retraction are very important for esthetics, stability, and function of teeth. In this research we analyzed, by Finite Element Method, the stress distribution on the periodontal ligament according to the variation of force and moment applied on the crown and predict the pattern of movement of maxillary central incisor. At the same time, the amount of force and moment caused by activation of the loop which was used for retraction of maxillary central incisor was analyzed by Finite Element Method. We observed the following results: 1) We could control the stress distribution on the periodontal ligament by proper moment/force ratio on maxillary right central incisor and predict the pattern of movement of maxillary right central incisor. 2) The amount of stress on the periodontal ligament as well as the moment/force ratio demanded by each pattern of movement increased as the destruction of alveolar bone was worse. 3) The moment/force ratio demanded by each pattern of movement decreased as the angle between the maxillary central incisor and occlusal plane decreased. 4) The force with the open loop was shown to be large compared to that with the closed loop. Also, the force with the helix decreased by 30% compared to that without the helix. 5) Under the same conditions we observed a larger moment/force ratio when the open loop and/or the helix were used.

본 연구는 경상남도 일대의 도로 및 산업단지 시공과정에 발생된 암반사면에 대하여 현장조사 및 기존 조사자료 등을 토대로 붕괴를 일으키는 여러 가지 요인들을 분석하여 붕괴 특성을 파악하고자 하였다. 직접 조사한 사면가운데 붕괴가 발생한 사면의 경우 붕괴특성을 분석하여 붕괴사면 자료의 계속적인 수집 및 데이터베이스 구축과 관리 및 분석을 통해 붕괴사면 예측 및 예방에 활용할 수 있을 것이다. 절토사면의 붕괴특성에 사용된 평가항목은 여러 가지 요인들 중에 기존에 사면 안정성 평가에 많이 사용된 평가항목을 비교하여 중복되는 요소들 중에 객관적인 평가항목으로 볼 수 있는 항목을 선택하여 사용하였다. 암반사면의 파괴유형은 기반암의 암종에 따라 평면파괴, 쐐기파괴, 원호파괴, 전도파괴 등의 양상이 다르게 발생하므로 사면의 안정성을 검토할 경우 반드시 지표지질 조사를 실시하여 기반암의 암종을 분석한 후 그에 따른 사면의 안정성 해석을 수행하여야 한다.

Degenerative joint disease(DJD) has hun known as one of the diseases which affect the middleor old-aged people. But as orthodontists are getting interested in the adult orthodontics, it is not rare for them to meet the open-bite patients with the TMJ DJD in their clinics. The purpose of this article is to investigate the cephalometric characteristics of the open-bite cases with TMJ DJD. Twelve TMJ DJD patients($15.1\~39.5$ years old) were selected from the patients who visited Department of Orthodontics, Seoul National University Hospital. Cephalograms were taken and means from 60 measurements were compared by t-test with those of the fifty four healthy adults($20.0\~26.7$ years old) who have normal occlusion and TMJ. In this study male and female are compared respectively, for in the normal samples 26 measurements showed significant differences between the male and the female. The results and conclusions axe as follows: 1 In DJD group, ANB and Angle of convexity decreased, which means the retruding of the mandible. The interincisal angle was smaller than that of the normal group. The means of the overbite were -2.1mm in male and -3.0mm in female, and the means of the overjet were 5.6mm in male and 6.7mm in female. The profile was similar to that of Angle's Class II div.1 open-bite. 2. SN-GoMe and FMA increased in DJD but SN-PP and FH-PP did not show any significant difference. In TMJ DJD open-bite cases, the bony structure lower than the palatal plane seemed to play an important role in developing open-bite. 3. In DJD group, PH-ArGo, SArGo and Y-sxis angle increased significantly, but genial angle showed no significant difference. The means of hか were 50.1mm in male and 40.2mm in female, which were significantly smaller than those of the normal(56.5mm in male, 50.9mm in female). These findings seemed to indicate the posterior rotation of mandible resulted from the shortening of the ramus height. 4. Anterior faical height(AFH), upper anterior facial height(UAFH) and lower anterior facial height (LAEH) of DJD showed no significant increase as compared with those of the noraml group. There was no significant difference in the ratio of upper anterior facial height to lower anterior facial height(UAFH/LAFH). But, lower posterior facial height(LPFH) was significantly smaller than that of the normal group. 5. It was thought that the peculiar profile of the TMJ DJD open-bite was resulted from the posterior rotation of mandible as the ramus became short following the degerative destruction of of the condylar head and neck.

저위교합이란 치아가 출은 이후 유착 등의 원인으로 맹출이 정지되어 주위조직이 정상적으로 성장함에 따라 정상교합보다 낮아진 상태를 말한다. 저위교합을 방치하는 경우 이환치의 만기잔존과 대합치의 정출 및 인접치의 경사에 따른 공간상실, 교합압과 식편압입으로 인한 인접치의 치주 조직 파괴와 치아우식 감수성의 증가, 계승치의 맹출경로 변위 또는 매복과 같은 문제점이 발생할 수 있으므로 정기검진을 통한 진단과 이에 따른 적절한 치료가 필요하다. 저위교합을 보이는 유구치의 치료방법으로는 후속 영구치의 유무, 저위교합의 발생 시기 및 진단 시기, 저위교합의 정도 등에 따라서 주기적인 관찰, 보존적 접근 방법, 수복치료, 교정적 방법을 통한 공간확장술과 발치 등이 있다. 본 증례에서는 상악 제2유구치의 저위교합 및 제2소구치 치배의 변위를 보이는 3명의 환아를 대상으로 가철성 교정장치를 이용한 공간확장술 및 유구치의 발치를 시행함으로써 변위되었던 제2소구치 치배의 정상 맹출을 유도하였다.

치아 우식, 치주 질환, 치아 파절 등으로 다수의 구치가 상실된 환자의 경우 대합치의 정출, 잔존 치아의 과도한 교합 하중으로 인한 교합 외상의 문제가 발생된다. 대합치 정출이 발생된 경우 인접 조직의 성장도 이와 동시에 발생되고 보철을 위한 악간 공간의 상실을 동반하게 되며 교합 외상으로 인한 치아에 동요도 증가 및 교모에 의한 마모도 증가하게 된다. 이러한 구치의 다수 상실, 대합치 정출 및 잔존치의 교모 증가를 동반한 환자에 있어서는 적절한 치주 수술(치관 연장술, 골 절제술 등) 및 수직 교합 고경의 회복을 통한 잔존 치아와 상실된 치아의 수복이 필요하게 된다. 본 증례의 환자는 상실된 구치의 수복을 주소로 내원한 환자로 구치부 상실 및 잔존치의 마모된 치열을 지녀보철 수복을 위한 공간을 위해 수직고경을 증가시켜 치료한 치험예를 문헌 고찰과 함께 보고하고자 한다.
