The purpose of this study is to identity the representative flower patterns in the Joseon Dynasty and investigate their chronological transitions. In the early Joseon Dynasty (i.e. 16th century), lotus patterns were very popular. Often lotus patterns were twisted around by ivy-leaves or decorated with treasures pattern in the margin. In the mid Joseon Dynasty (i.e. from 17th to mid 18th century), however, lotus patterns evolved from the typical lotus and ivy pattern and diversified into four types. In the 19th century, lotus pattern almost disappeared from the textiles of everyday dresses and were only found in the textiles of formal dresses or in special cases as in the cover pages of Buddhist scriptures. Poeny patterns was rarely used in textiles of 16th century, presumably because of the huge popularity of the lotus pattern. However, suddenly in the 17th century, Poeny patterns appeared quite frequently. There were 3 types of Poeny patterns. Poeny patterns became more popular over the years and it finally became a primary motive in textiles patterns for 100 years starting in the late 19th century. There were two types of Poeny patterns : one was realistic and true to life even in sizes, the other was more symbolic. Textile patterns combining four kinds of flowers started to appear from the late Koryo Dynasty but Flower patterns representing four seasons with distinct shapes appeared only in the 17th century. They could be categorized into three types. In the late 18th century, Flower patterns representing four seasons no longer appears in textile patterns, presumably due to a new preference for lucky omen over natural motives.

What do our mathematics teachers now do in the classroom？ What does it actually mean to teach mathematics？ Every preparatory mathematics teacher is confronted with these questions since they have studied to become a teacher. Almost all in-service teachers are faced by of questions, too, as they evaluate their teaching in the light of that of their colleagues. In this sense, Jon L. Higgins has proposed mathematics teaching patterns of five categories, i. e., exploring, modeling, underlining, challenging, and practicing, for the sake of our all teachers. Next, J. P. Guilford has suggested three faces of intellect presented by a single solid model, which we call the 'structure of intellect' Each dimension represents one of the modes of variation of the factors. It is found that the various kinds of operations are in one of the dimensions, the various kinds of products are in another, and the various kinds of contents are in the other one. In order to provide a better basis for understanding this model and regarding it as a picture of human intellect, I've explored it systematically and shown some concrete examples for its tests. Each cell in the model stands for a certain kind of ability that can be described in terms of operation, content, and product, for each cell is at the intersection uniquely combined with kinds of ope- ration, content, and product. In conclusion, how could we use the teaching patterns of five categories, that is, exploring, modeling, underlining, challenging, and practicing, according to the given mathematics learning substances？ And also, how could children constitute the learning sub- stances well in their mind with a viewpoint of constructivism if teachers would connect the mathematics teaching patterns of five categories with any factors among the three faces of intellect？ I've made progress this study focusing on such problems.

After I stated the characteristics of the ancient Buddha Banners of Shoso-in and Horyuji of Japan, 1 searched for the possible countries they could have been made in. 1 concluded that Japan imported above mentioned Buddha Banners from Korea from the fallowing reasons: 1. Almost no Banners in Heian Period. 2. Difference between Banner patterns of Nara period and them of Heian period. 3. Japan almost always imported Buddhist implements including Banners from Korea from 7th century 4. Resemblances between kinds and forms of the patterns of Shoso-in and Horyuji Banners, and them of Silla period.

This study aims to develop jacquard fashion masks using traditional patterns and investigates the preference and emotions of consumers for them. Nine patterns were designed with the motifs of plum flower, turtle, and geometric patterns using an Adobe Illustrator program. After that, 20 kinds of jacquard fabrics were developed using those patterns, and prototype masks were made. Furthermore, data were collected using a survey of 231 adult consumers to understand the emotional images evoked by jacquard fashion masks with traditional patterns. The results of the research show that the emotional dimension derived from jacquard fashion masks with traditional patterns consists of seven factors: luxurious image, frugal image, feminine image, oriental image, sporty image, geometrical image, generous image. We found that consumers preferred the M6 with the plum flower pattern as the motif as the most preferred design, while M13 with the geometric pattern as the motif was the lowest preferred.

This research was designed to study the Korean dress design trends and different kinds of ancient patterns applied to the Korean dresses in 2001. The trend sources were collected by the HANBOK monthly journal and the symbolism of patterns associated with these patterns being used the prevalent Korean dress collection in markets. The results of the research can be summarized as following; The most of Korean dress image was elegant of ancient mode. Main colors of the traditional Korean jacket were white, yellowish white and green. However, main color of the traditional Korean skirt was represented as red. A plant pattern was the most popular pattern in a practical purpose. It looks beautiful and it is also easily manufactured with open space. Copying other patterns definitely damage the elegance of the Korean dress. It is time for us to not only keep our own traditions but also study and develop new patterns. Designers must study to develop the image and patterns which are agreed with consumer's taste.

In this paper, we proposed an algorithm to detect aggressive driving status by analysing six kinds of driving patterns, which was achieved by comparing for the feature vectors using mahalanobis distance. The first step is to construct feature matrix of $6{\times}2$ size using frequency response of the time-series accelerometer data. Singular value decomposition makes it possible to find the dominant eigenvalue and its corresponding eigenvector. We use the eigenvector as the feature vector of the driving pattern. We conducted real experiments using three drivers to see the effects of recognition. Although there exists differences from individual drivers, we showed that driving patterns can be recognized with about 80% accuracy. Further research topics will include the development of aggressive driving warning system by improving the proposed technique and combining with post-processing of accelerometer signals.

It is studied that the typical garments of Korea Dynasty, especially focused on half-sleeved Saeng jo Po and conspicuous kinds of fabrics,. Characteristics of this Po are doubled collar, pleats, half-sleeved, a partial lining sewed in the back of an unlined coat, a breast-tie, and so on. It is that a girdle of Po had been used from the early Korea Dynasty, contrary to the general theory that a girdle of Po was the special characteristic of early Korea Dynasty in the garments history of Korea. It is that the species, it is that there are may characteristic way of patterns in the Korea Dynasty, such as turtle patterns, cloud patterns, swastika patterns. etc.

This research suggests pattern design methods for motion through an evaluation of the appearance and motion of three existing kinds of original patterns (K type, N type, and L type) and modified patterns designed by the researcher. The results of the study are as follows. First, the evaluation of appearances showed that the modified patterns of a standing posture received a higher evaluation compared to the original patterns only in N type and in a sitting posture. In addition, the degree of lowering or a natural feel by the pulling of the slacks waist belt in a sitting posture received a higher evaluation than the original patterns. Second, the evaluation of motions showed that modified patterns received a higher evaluation than the original patterns in almost all items. Per each pattern, it showed meaningful differences in questions asking about the degree of comfort as the whole in N type in crouching motions. The L type showed low scores as a whole (both in original patterns and modified patterns) and the K type showed meaningful differences in questions asking about the degree of comfort of the crista iliaca and groin region in the motion of walking at a normal walking pace, ascending stairs and bending the waist 90 degree to the front. Third, the measuring distance the between back waist point of the body and the back waist point of original patterns and modified patterns during motions showed that the modified patterns of all three patterns (N type, L type, and K type) showed less lowering compared to the original forms in the whole pattern as well as individual patterns. The design method of back waist point developed in this research can be regarded as a design method appropriate for motions.

The organic acids in 3 kinds of medicinal herbal extracts were screened and compared each other according to their organic acid contents by an efficient gas chromatographic method. It involves solid-phase extraction of organic acids using Chromosorb P with subsequent conversion to stable tert-butyldimethysilyl derivatives for the direct analysis by capillary column gas chromatography and gas chromatography-mass spectrometry. Total of 24 organic acids were reproducibly identified from 3 kinds of herbal extracts. When the GC profiles were simplified to their retention index spectra, characteristic patterns were obtained for each herb sample. As expected, three kinds of herbal extracts showed three distinct patterns.
