It has been issued to fabricate nano-scale patterns with large-scale in the field of digital display. Also, large-scale fabrication technology of nano pattern is very important not only for the field of digital display but also for the most of applications of the nano-scale patterns in the view of the productivity. Among the fabrication technologies, UV nano imprinting process is suitable for replicating polymeric nano-scale patterns. However, in case of conventional UV nano imprinting process using flat mold, it is not easy to replicate large areal nano patterns. Because there are several problems such as releasing, uniformity of the replica, mold fabrication and so on. In this study, to overcome the limitation of the conventional UV nano imprinting process, we proposed a continuous UV nano imprinting process using a pattern roll stamper. A pattern roll stamper that has nano-scale patterns was fabricated by attaching thin metal stamper to a roll base. A continuous UV nano imprinting system was designed and constructed. As practical examples of the process, various nano patterns with pattern size of 500, 150 and 50nm were fabricated. Finally, geometrical properties of imprinted nano patterns were measured and analyzed.

This study aims to suggest a bag design focusing on the symbol of Bo patterns by developing a pattern-based textile which forms a Korean design with a modern sense of beauty as well as following the conventions of traditional cultures, a design which is based on the previous study on formative characteristics of Bo patterns. That is, seven pieces of motifs are considered as proper patterns that have a symbol suitable for the materials of bags, showing their individual beauty well. This includes Horomum (longevity and prosperity of desendants), Banjangmum (eternity and samsara), Jeonbomum (treasure and luck), Seobomum (innate good fortune), Bangseungmum (it means that things don't break in harmony with one another), Bomum (embroidered patches for royal family representing justice), and Seogakmum (blessed life). With these seven motifs, we developed textile patterns and printed them through DTP. Then, we created a fashion bag design with a high quality using durable canvas fabrics. Therefore, a fashion bag with the Bo patterns symbol has a propitious symbol designed with a propitious shape, not to mention its formative beauty. It is expected to have value as a fashion art item by being redesigned for benevolent patterns with a modern image.

From ancient times. lotus pattern had esthetic factor and symbolic factor. Lotus pattern was introduced to China, and it was grafted together with Chinese peculiar culture symbol system, thereafter it has changed and developed. The Chinese taking a serious view meaning that things include, and they frequently use several lucky omen patterns in their everyday life. In this study, I investigated laying stress on symbolism about Lotus patterns of China lucky omen patterns, and I wanted to present possibility that can approach to Chinese culture in new angle. Through result of this study, symbol of Lotus patterns can divide two directions. First, symbol by natural properties of lotus are same as following. 1. Lotus grows in the mud, but it is uncontaminated - clearness and uprightness, 2. Root, branches, loaves and flowers are vegetative together, and all of basis and branches are exuberant. - plenty, 3. Bear fruit simultaneously with blooming, and it is procreant. - fecundity and many descendants. Symbol that use same pronunciation and intention are same as following. 1. 'Lian(연)'-'Lian(연)' : repeatability, continuance, plenty and intercommunicate, 2. 'Lian(연)'-'Lian(염)': integrity, 3. 'He (하)'-'He(화)' : peace, harmony and combination, 4. 'He(하)'-'He(하)' : clear river, 5.'He(하)'-'He(하)' ; all work goes well. When the Chinese use lotus patterns in lucky omen patterns, same pronunciation and pitch of Chinese language more prominent than natural properties or the image of Buddhism. I guess that it cause praying individual's peace and happiness more serious than philosophical meaning or symbol that base in Buddhism for ordinary people.

The present study investigated what kind of form-focused instruction would yield better results for incidental learning of English verb patterns in two experiments. Experiment 1 compared the effectiveness of focus on form (reading + translation) and focus on forms (verb pattern list + translation) tasks in learning new English verb patterns incidentally in Korean EFL college classrooms. The results of Experiment 1 showed significantly higher results for the focus on forms group. Since it was revealed by Experiment 1 that the learners did not notice unknown target verb patterns, Experiment 2 was undertaken to examine whether the difference between the focus on form and focus on forms conditions found in Experiment 1 would be retained even after the isolated form-focused instruction or focus on forms aiming at teaching students how to recognize verb patterns was provided for the learners before the focus on form and focus on forms tasks were carried out. The results showed that the focus on form group yielded significantly higher incidental learning scores than the focus on forms group. The effectiveness rates of the focus on form in Experiment 2 were statistically higher than those of the focus on forms in Experiment 1. The results of the two experiments indicated that the combination of the isolated form-focused instruction and focus on form was significantly more effective in learning English verb patterns incidentally. In conclusion, form-focused instruction including both isolated form-focused instruction and focus on form is an effective way to incidental learning of English verb patterns.

The study has examined about the origin and change of traditional Japanese dress "Kosode" and classified it according to its ages and also classified its patterns which appeared on the Kosode by its kinds, and divide the patterns with constituent method and expressional method and so, studied and analyzed them with type of patterns according to the change of the times. The result of research were as follows: 1. Subject of patterns that appeared on the Kosode was used with mainly plant pattern, animals pattern, pictorial pattern, artificial pattern, and abstract patterns. 2. Expressional method of this patterns was mostly expressed simply with tie dyeing in ancient times, but it changed complex its expressional method and diversely due to the development of common's culture as time goes on. 3. For the arrangement of its pattern were arranged regularly mostly make demarcate and though they are as if seemed dispersed, but a characteristic that can find regulations in it. 4. Transition of patterns that appeared on the Kosode it developed at the beginning of ancient syouboon, Katasuso pattern and Katamigaori patterns at the samurai's society in the medieval society and developed to Koicho kosode and Kambun kosode in modern times.

This paper suggests a method to recognize the various defect patterns of a cold mill strip using a binary decision tree automatically constructed by a genetic algorithm(GA). In classifying complex patterns with high similarity like the defect patterns of a cold mill stirp, the selection of an optimal feature set and an appropriate recognizer is important to achieve high recognition rate. In this paper a GA is used to select a subset of the suitable features at each node in the binary decision tree. The feature subset with maximum fitness is chosen and the patterns are classified into two classes using a linear decision function. This process is repeated at each node until all the patterns are classified into individual classes. In this way, the classifier using the binary decision tree is constructed automatically. After constructing the binary decision tree, the final recognizer is accomplished by having neural network learning sits of standard patterns at each node. In this paper, the classifier using the binary decision tree is applied to the recognition of defect patterns of a cold mill strip, and the experimental results are given to demonstrate the usefulness of the proposed scheme.

This study was aim to compare the phonological error patterns and PCC(Percentage of Correct Consonants) derived from the single word and spontaneous speech contexts of the speech sound disorders with unknown origin(SSD). The present study suggest that the development phonological error patterns and non-developmental error patterns of the target children, in according to speech context. The subjects were 15 children with SSD up to the age of 5 from 3 years of age. This research use 37 words of APAC(Assessment of Phonology & Articulation for Children) in the single word context and 100 eojeol in the spontaneous speech context. There was no difference of PCC between the single word and the spontaneous speech contexts. Significantly different developmental phonological error patterns between the single word and the spontaneous speech contexts were syllable deletion, word-medial onset deletion, liquid deletion, gliding, affrication, fricative other error, tensing, regressive assimilation. Significantly different non-developmental phonological error patterns were backing, addtion of phoneme, aspirating. The study showed that there was no difference of PCC between elicited single word and spontaneous conversational context. And there were some different phonological error patterns derived from the two contexts of the speech sound disorders. The more important interventions target is the error patterns of the spontaneous speech contexts for the immediate generalization and rising overall intelligibility.

In this paper, cavitation patterns of model tests were compared with those of full-scale measurement for a propeller of crude oil carrier which was suffered from erosions on suction side of blade tip region. Cavitation tests were performed at design and ballast draft using model and full scale nominal wakes. A model ship and wire mesh method was used for the simulation of wake patterns of model nominal wakes. For the prediction of full-scale wake patterns, a RANS solver(Fluent 6.3) was used and wire mesh method was used for the simulation of the full scale wakes. Comparison results show that cavitation patterns using predicted full-scale wake patterns are closer to cavitation patterns of full-scale measurement at ballast draft condition. Also, cloud cavitations were observed on the position of eroded area at both full-scale measurement and cavitation tests using simulated full-scale wake patterns.

We explored localized plasmonic field enhancements using nanowire patterns to improve the sensitivity of a surface plasmon resonance (SPR) sensor. Two different materials, gold and silver, were considered for sample materials. Gold and silver nanowire patterns were fabricated by electron beam lithography for experimental measurements. The wavelength SPR sensor was also designed for these experiments. The material-dependent field enhancements on nanowire patterns were first calculated based on Maxwell's equations. Resonance wavelength shifts were indicated as changes in the refractive index from 1.33 to 1.36. The SPR sensor with silver nanowire patterns showed a much larger resonance wavelength shift than the sensor with gold nanowire patterns, in good agreement with simulation results. These results suggest that silver nanowire patterns are more efficient than gold nanowire patterns, and could be used for sensitivity enhancements in situations where biocompatibility is not a consideration.

Objective : The purpose of this study was conducted to find correct head and neck patterns, manual contact. verbal commands with proprioceptive neuromuscular facilitation(PNF). Method : This is a literature study with books, seminar note and book for PNF international course. Result : Keep the information of the biomechanics and neural science in head and neck patterns and emphasize that manual contact, verbal commands and visual stimulus. Manual contacting for movement guide and stability of the $C_0/C_1$ verbal command and visual stimulus for correcting of the $C_0/C_1$ movements. Conclusion : In reminder for PNF learning, begin with head and neck and upper trunk patterns. In that time, Knott and Voss(1968) had not enough information about biomechanic movement components and neural science movement components. But Knott and Voss(1968) emphasized that head and neck patterns relate with trunk, upper extremities and lower extremities directly. Alar ligaments are relaxed with the head in neutral and taut in flexion. Axial rotation of the head and neck tightens both alar ligaments. The right upper and left lower portions of the alar ligament limit left lateral flexion of the head and neck. Therefore, head and neck patterns has to be modify. When head moving, eye and vestibular stimulus will be change. During head and neck patterns, must be consider about stimulus of eye system and vestibular system also.
