The purpose of this study was to evaluate the morphology of mandibular symphysis and location of lower incisor under the influence of the craniofacial skeleton in skeletal Class III malocclusion. The sample consisted of 132 adults who have severe Class III malocclusion(prognathism group, 33 males and 33 females), and who have normal occlusion(normal group, 33 males and 33 females). They had not received any orthodontic treatment or orthognathic surgery. The lateral cephalograms were evaluated. The results were as follows : 1. Prognathism group were larger than normal group in comparison of facial skeleton (p<0.05) with the exception of ${\angle}FH-Pal$, ${\angle}SNA$. 2. In the morphology of symphysis, measurements of anteroposterior width(LaABBW, LiABBW, SW) of prognathism group were significantly less than that of normal group(p<0.001). 3. In the correlative analysis between the craniofacial skeleton and symphysis measurements of prognathism group, vertical measurements in relation with cranial base and mandibular plane showed reverse correlationship with anteroposterior width of symphysis(LiACBW, LaACBW, LiABBW, SW)(p<0.05). But, there was not distinct difference between horizontal skeletal measurements and symphysis measurements(p>0.05). 4. The probability by regression test between vertical measurements(${\angle}SN-Mn,\;{\angle}FMA,\;{\angle}Pal-Mn,\;{\angle}LFH$) and symphysis measurements(LiACBW, LiABBW, SW, ${\angle}LISA$) were very high(p<0.001).

Delayed eruption and abnormal morphology of the primary incisors following intubation may be due to follicular displacement and localized trauma caused by the process of intubation. Result of such damage included palatal groove formation, defective incisors and acquired clefts. This clinical report presents effect of intubation on the primary dentition of premature low-birth-weight children prior to tooth eruption.

Considering an integral equation governing the motion of unfolding fin, an algebraic equation was acquired to get estimated minimum deployment energy required for the successful fin unfolding under the given wind condition. To complete the integration of moment, some approximations had to be introduced particularly to frictional moment and aerodynamic damping for which deployment angular speed of the unfolding fin was modelled as a function of deployment angle only with assumed profile using expected maximum angular speed. Technique for the estimation of the minimum required deployment energy was finalized by introducing the ideal deployment angular speed representing work done by the fin unfolding device alone during fin unfolding and was confirmed by comparing results from simulation with various aerodynamic conditions and profiles of the hinge torque.

베어링을 이용한 회전축은 모든 회전축의 근간을 이루고 있다. 이러한 회전축은 발전기 터어빈, 고정밀 공작기계 등에 많이 응용되고 있다. 그런데 이러한 대규모의 회전축에 이상이 생긴 경우, 이상을 방치하고 계속 사용하게 되면 기계전체의 파손을 가져올 수 있다. 이러한 기계전체의 파손이 일어나지 않도록 미리 이상을 진단할 수 있는 시스템을 구축하면 많은 비용을 절감할 수 있다. 지금까지 여러 종류 로터시스템 여러 종류의 이상진단을 시도하여 왔으며 앞으로도 많은 종류의 이상진단이 이루어지리라 생각한다. 다양한 형태의 이상진단은 시스템에서 추출되는 데이터를 통계적으로 처리하는 기법과 추출하는 센서의 특징을 파악하여 이상진단 알고리즘을 수립하는 과정을 망라하게 된다. 특히 이상진단 알고리즘에는 측정된 데이터의 불확실성을 감안한 이론이 적용되어야 한다. 본 논문에서는 로터시스템을 이용한 베어링 진단 유무에 대한 이상진단을 통계적 패턴인식 이용하여 정상과 비정상 상태를 구분하여 여러 종류의 이상을 구분하는 작업수행을 연구하고자한다.

The lateral meniscus is morphologically more variable than the medial meniscus. An abnormal lateral meniscus also varies with respect to its size, shape and stability, and such variations can occur in any patient of any age. The most common variant is a discoid lateral meniscus. We recently encountered a patient with a discoid lateral meniscus for which the anterior horn of the meniscus was anomalously inserted into the anterior ACL. The patient was forty five years old women who had persistent pain for three to four years without any specific trauma history. She was preoperatively diagnosed as having discoid lateral meniscus by MRI, and was confirmed the presence of the complex tear and anomalous insertion of the anterior horn of the discoid lateral meniscus into the anterior ACL by arthroscopic examination. Arthroscopic subtotal meniscectomy was performed and the symptoms were improved after surgery.

Morphological characteristics of 16 collected safflower (Carthamus tinctorius L.)accessions were studied at Gyongbuk A.T.A. Uisong Medicinal Plant Experiment Station in 1998. As for plant height, 5 lines were tall(more than 131cm), which were mainly foreign safflower. Middle and small were 5 and 6 accessions, respectively. Number of branch per plant was 11∼13 in 2 accessions of domestic safflowers while foreign safflowers have more than 50 branches per plant. Leaf shapes were oblong(3 lines), lanceolate(10 lines) and broadly linear(3 lines). There were three types of leaf margin shape which were repand(7 lines), serrate(4 lines) and parted serrate(5 lines). Flower color was white(1 line), yellow(13 lines) and red orange(2 lines). As for flower head shape, 14 lines were conical and 2 lines were flattened. There were thorns on bract of flower head in 11 lines but in 5 lines there were not. Domestic safflower lines had seeds of conical shape. Contrastively, seed shapes of foreign saffower lines were oval.
