The author observed the eruption pattern of mandibular anterior teeth by orthopantonography taken by children who came to pedodontic department, school of dentistry, S.N.U. and then got the following results. 1) In the degree of eruption pattern of anterior teeth, female is slightly faster than male. 2) Eruption pattern of central incisors was similar to lateral incisor, but the degree of lateral incisors movement was more severe. 3) Eruption pattern of canine was out of normal process when the adjacent teeth were abscence and there was not distal movement such as in maxillary canine.

그래프마이닝에서 그래프패턴의 동형판단문제는 지수함수적 계산시간을 요구하기 때문에 그래프마이닝의 전체수행시간에서 동형판단 연산이 차지하는 비율이 매우 높다. 그러므로 그래프마이닝 알고리즘은 그래프동형판단을 최대한 효율적으로 할 필요가 있다. 본 논문은 그래프마이닝에서 빠른 수행시간을 보이는 gaston 알고리즘의 동형판단효율성을 증가시켜 수행시간을 평가해 보았으며, 제시한 방법으로 인해 더욱 향상된 성능을 보인다.

Korean college students' experience in studying English overseas playes the significant role to their perception, not production. Korean Group which experiences foreign-stay for almost 1 year shows the similar pattern with its counterpart, Korean Non- Experiencing Group, in producing the signal of pre-vowel. On the contrary, Korean Experiencing Group shows the similar perceptual pattern with Native Speakers in word-final non-release stops.

To achieve the aim of this study, 9 different types of samples were made to examine mechanical property according to structured pattern and type of Machi of pullover armhole of WholeGarment(seamless knitwear). With respect to samples, from which comparisons are made and anaylzed among basic characteristics of material, tensile strength & elongation and residual elongation due to repeated extension of armhole connecting part, the following conclusions could be obtained. It's revealed that the tensile strength of Machi part as being armhole connecting part of samples is more affected by Machi type than pattern structure. Of Machi types, it showed stronger tensile strength in the order of Normal(Normal Machi)< Machi_B(unilateral Machi)

In this paper, we applied the high-performance PGAP(Parallel Genetic Algorithm Processor) to recognizing rotated pattern. In order to perform this research efficiently, we used Multi-PGAP system consisted of four PGAP. In addition, we used mental rotation based on the rotated pattern recognition mechanism of human to reduce the number of operation. Also, we experimented with distinguishing specific pattern from similar coin patterns and determine rotated angle between patterns. The result showed that the development of future artificial recognition system is feasible by employing high performance PGAPS.

Noncontact measuring methodology of 3-dimensional profile using CCD camera are very attractive because of it's high measuring speed and its's high sensitivity. Especially, when projecting a grid pattern over the object the captured image have 3 dimensional information of the object. Projection moire extract 3-D information with another grid pattern in front of CCD camera. However phase measuring profilometry(PMP) obtain similar results without additional grid pattern. In this paper, new method for grid pattern generation system by polygonal mirror and Laser Diode. This system is applied the projection moire and the PMP.

Pattern-based query processing has not attracted much attention in wireless sensor network though its counterpart has been studied extensively in data stream. The methods used for data stream usually consume large memory and much energy. This conflicts with the fact that wireless sensor networks are heavily constrained by their hardware resources. In this paper, we use piece wise representation to represent sensor nodes' collected data to save sensor nodes' memory and to reduce the energy consumption for query. After getting data stream's and patterns' approximated line segments, we record each line's slope. We do similar matching on slope sequences. We compute the dynamic time warping distance between slope sequences. If the distance is less than user defined threshold, we say that the subsequence is similar to the pattern. We do experiments on STM32W108 processor to evaluate our strategy's performance compared with naive method. The results show that our strategy's matching precision is less than that of naive method, but our method's energy consumption is much better than that of naive approach. The strategy proposed in this paper can be used in wireless sensor network to process pattern-based queries.

The number of sites at which a protein can be readily cleaved by a proteolytic enzyme is greatly influenced by its three-dimensional structure. For native, properly-folded proteins both the rate of cleavage and number of sites at which cleavage takes place are usually much less than for the denatured protein. In order to compare the tertiary structure of recombinant HepG2 type glucose transporter with that of its native counterpart in the erythrocyte, the pattern of tryptic cleavage of the protein expressed in insect cell membranes was therefore examined. After 30 minutes digestion, a fragment of approximate Mr 19,000-21,000 was generated. In addition to this, there were two less intensely stained fragments of apparent Mr 28,000 and 17,000. The pattern of labelling was similar up to 2 hours of digestion. However, the fragments of Mr 19,000-21,000 and Mr 17,000 were no longer detectable after 4 hours digestion. The observation of a very similar pattern of fragments yielded by tryptic digestion of the HepG2 type transporter expressed in insect cells suggests that the recombinant protein exhibits a tertiary structure similar if not identical to that of its human counterpart. Also, the endogenous sugar transporter(s) present in Sf21 cells did not bind cytochalasin B, the potent transporter inhibitor. Therefore, the baculovirus/Spodoptera frugiperda (Sf) cell expression system could be very useful for production of large amounts of human glucose transporters, heterologously.

One of the most important functions of a biped robot is to walk naturally like human. For the human being, toe is very important joint in order to walk naturally. Thus, for a biped robot, the existence of toe joint much affects gait pattern generation and contributes to natural walking, which is similar to the human gait or faster walking like running. Since a conventional biped robot has the feet which consist of soles without toes, it seems difficult to walk naturally. For realizing the gait to be similar to human one, toes are necessary to the biped robot. In this paper, the effect of the toe joint for gait pattern generation is studied. In order to find the effect of toe joint, a biped r...

Study on Hwal-ot, woman's wedding robe of the Joseon Dynasty, has been limited to the Princess Bock-on's Hwal-ot and some folk remains. In this study, I tried to identify formative characteristics of Hwal-ot by studying embroidery design patterns in the royal Hwal-ot. On Mar 26, 2007, I inspected total of 15 pieces of embroidery design patterns for Hwal-ot held at the National Palace Museum of Korea. I classified them into three types of Hwal-ot by considering characteristics in embroidery design patterns as well as composition of embroidery design patterns held by the private. For the Hwal-ot embroidery design pattern type I, there is a calligraphy called "Embroidery Design Pattern of Red Long Robe for leo-dong Palace", which is presumed to be the embroidery design pattern of Princess Deok-on, the third daughter of King Sunjo and a little sister to Princess Bock-on. Its patterns are very similar to that of Princess Bock-on's, with similar flower patterns and treasure patterns, as well as overall stripy structure. The Hwal-ot embroidery design pattern type II maintains the same flower patterns and butterfly patterns as in the type I, but does not have the striped decorative. The Hwal-ot embroidery design pattern type III has illustrative design with waves and mountain at the background and a pair of water birds flying around lotus. In particular, the type III design has a nine phoenix pattern at the front part of the robe, illustrating nine baby phoenixes (four in the left, five in the right) under a mother phoenix, which is closer to characteristics found in the Hwal-ot embroidery design patterns at the end of the Joseon dynasty.
