  • Mathematical symbolizing is an important part of mathematics learning. But many students have difficulties m symbolizing mathematical ideas formally. If students had experiences inventing their own mathematical symbols and developing them to conventional ones natural way, i.e. learning mathematical symbols via expressive approaches, they could understand and use formal mathematical symbols meaningfully. These experiences are especially valuable for students who meet mathematical symbols for the first time. Hence, there are needs to investigate how early elementary school students can and should experience meaningful mathematical symbolizing. The purpose of this study was to analyze students' mathematical symbolizing processes and characteristics of theses. We carried out teaching experiments that promoted meaningful mathematical symbolizing among eight first graders. And then we analyzed students' symbolizing processes and characteristics of expressive approaches to mathematical symbols in early elementary students. As a result, we could places mathematical symbolizing processes developed in the teaching experiments under five categories. And we extracted and discussed several characteristics of early elementary students' meaningful mathematical symbolizing processes.

  • This study investigated the understanding level and the using level of mathematical language for middle school students in terms of Freudenthal' language levels. It was proved that the understanding level task developed by current study for geometric concept had reliability and validity, and that there was the hierarchy of levels on which students understanded mathematical language. The level that students used in explaining mathematical concepts was not interrelated to the understanding level, and was different from answering the right answer according to the sorts of tasks. And, the level of mathematical language that was understood easily as students' thought, was the third level of the understanding levels. Mathematics teachers should consider the students' understanding level and using level, and give students the tasks which students could use their mathematical language confidently.

  • Word representation, an important area in natural language processing(NLP) used machine learning, is a method that represents a word not by text but by distinguishable symbol. Existing word embedding employed a large number of corpora to ensure that words are positioned nearby within text. However corpus-based word embedding needs several corpora because of the frequency of word occurrence and increased number of words. In this paper word embedding is done using dictionary definitions and semantic relationship information(hypernyms and antonyms). Words are trained using the feature mirror model(FMM), a modified Skip-Gram(Word2Vec). Sense similar words have similar vector. Furthermore, it was possible to distinguish vectors of antonym words.

  • The aspects of contemporary society change have been changed rapidly running for function value on the part of part industrialization and information-oriented. The transfer to the society focused on a human being emphasis and symbol value is in progress rising with natural desire of recurrence of human nature accordingly and desires of a human being inborn of sensitivity-oriented and pluralism-oriented are being expressed. Answering these social and cultural demands, concerns about an arbitrary mind world of a human being and pursuit dispositions about impractical and transcendental world are coincided with to the purpose and so various kinds of expressions except for art sphere are being experimented and applied. Here upon also in the field of the contemporary interior design, answering sensual desire of users, various arts and cultural tendency, the concept of surrealism is being applied in design introducing the concept of surrealism positive. And fantastical and unreasonable expression features of surrealism are being used as subjective essential elements to make new spaces. Especially amoung various kinds of the interiors designs, the features like surrealistic expressions in Food & Beverage Space which proper identity and strong symbolism will be expressed can be recognized as appropriate expression patterns to give still more sensitivity stimuli to customers. Thus this research disclosed conceptual and ideological background of surrealism and also analyzed and studied surrealistic expression features applied to the interiors designs of Contemporary Food & Beverage Space through expression disposition, study and classification of techniques. And standing on the result of analyzing surrealistic expression features of Contemporary Food & Beverage Space with a key word of expression features derived we groped for estatescape trend demanded in Food & Beverage Space and direction coming.

  • The costume originated from the idea that it could protect human beings from ferocious beasts. The military costume was from protection against an enemy equipped with weapons. Furthermore, the makers of the costume were afraid of supernatural powers and it made them devise an armour and decorate it by the concept of superstition for the purpose of overcoming it. The function of military uniform was important for increasing the protection against any enemies while they join in battle. However in harmonious time, it represented artwork of peace, dignity, and order. Since the uniform was a king of symbol to show their position, and their role. They could feel proud as a member of a military group they belong to and they gain honor, courage, patriotic sentiment through their military costume. The purpose of this study was to investigate the originality the military costume as it changed and developed continuously from ancient Egypt, Greece and Rome to modern times. This study was performed to show the comparison and characteristic marks of the past, and the influence of them on the modern military uniform. The method used in this study was using past manuscripts of the early times, information attained from domestic and foreign military documents and previously written reports. As a result, the military costume was one of many means of expression of their natural and social environment. It can be said that the most epoche-marking and powerful changes to the social environment are revolution or war. War absolutely has influenced on the changes of the changes of costume and the military armour according to the type of war and the development of weapons. Especially using the amour, the main purpose that of protecting the body has changed into distinguishing our forces from the enemy and instilling fear into enemy, Furthermore, the class who has the power has used it in order to express their power and dignity.

  • This study is focused on two things, on the matter of judge's robe(JR) which is worn in the court. First, Korean JR were examined from late 19th century through today(1997)to reveal the entity of the JR : characteristics of each JR has been changed according to the political or international influences. Second, JR from 92 countries were collected and analyzed to figure out the plastic characteristics of the JR among international society. The results are as follows : First, Korean JR were have changed many times according to the social, political influences. The Korean modern judicial system were proclaim in 1895 and JR were adapted in 1906. In 1920, Japanese style JR were worn until 1945 when Korean government have had her Independence. Korean Government have changed JR through which Korean identities were expressed through patterns such as national flower Mukungwha(Hibiscus) and Yang & Yin. In 1966 Korean JR were changed again and adopted western style JR until today (1997) which have many things in common with academic robe of university or clerical robe. Second, the analysis of the 92 international JR were summarized as follows : (1) The JR were consisted of three styles such as Gown style, Cape style and Jacket style. And Gown style has been found as the most popular style(86%) for JR among them. (2) As the main color of JR, black is used among 60% of countries and red is used in 33% of countries. Gold were matched for black JR and gray for red JR as their sub-color. (3) The most popular material were wool and satin were favored as its sub-materials. (4) Natural and Geometric Patterns were used to express the symbol of the country and the court. (5) Decorative items and details such as hat, gloves, shoes, wig, necklace, neck-tie, stole, tassels, rope, ruffles were used to express wearers dignity and symbolism. These results are expected to be adapted for the future design for new JR which has its identity and characteristics.

  • This study aims at analyzing the formativeness of women fashion shoes shown in the high fashion since 2000 along with the necessity of study for such purposes. Fashion shoes designed for the perfection of high fashion have been positioned as an important item to increase the value of fashion. Subsequently, three formative images through the research method under the literature study could be analyzed as follows. First, the Fetishism image appeared from 18th century and the shoe heel has the erotic internal beauty while attracting the erotic nature from the perspective of 'feet confinement'. The high heel came to have an absolute relationship with the feminine beauty, and the feet and shoes are accepted for the erotic symbol regardless of anyone in the East or West. Second, the fashion shoes in the Maximalism image to pursue for the dream and excitement at the same time have been shown at the same time by using various ornaments in an exaggerated manner for the use of ornaments to clothes through designs by shoe designers. Third, the Aristocratism image in the fashion shoes was remarkably highlighted with the use of materials from processing natural materials with the best quality, which was expressed in an exotic manner with roughness and comfort despite the nature of refinement balanced with the simple reactionary tendency and technical senses of handicrafts. It can be perceived that the inner emotions of human beings are expressed by intentionally dismantling the functions of shoes in terms of functionality even in the fashion shoes in completing the ideal images after which are pursued by people.

  • This study purposed to restructure representative traditional patterns formatively, manufacture actual cultural products with traditional dyeing technique using persimmon, and commercialize the results of the research. Traditionally in Korea, the dying of natural fiber such as cotton, flax and silk with persimmon was called Galmul dyeing, and clothes made through Galmul dyeing were called Galot. Galot was very useful because it is strong, does not pick up dirt easily, dries easily, and is cool in summer. In addition, cloth dyed with persimmon becomes stiff, so it does not need to be starched or ironed after washing. Moreover, it does not transmit heat under direct rays and is highly air-permeable, so it is cool and useful for standing the heat. In this study, we used traditional persimmon dyeing technique, printing traditional patterns fit for contemporary people's aesthetic sense not through dip-dying but through printing. When persimmon dyeing is used in expressing patterns, it produces not only visual effect but also embossing effect due to the characteristic of persimmon that makes printed patterns stiff, so we can obtain unique texture distinguished from other printing methods. We chose seven motive patterns, which were lotus pattern symbolizing eternal life, peony pattern symbolizing wealth and rank and prosperity, character Su(壽) pattern widely used as a symbol of health, bird and cloud pattern in the Goryeo Dynasty, Sahapyeoeuisohwa(四合如意小花) pattern printed on brocade in the Goryeo Dynasty, lattice pattern, cloth pattern on wall paintings from the Period of the Three Kingdoms. From each pattern chosen as a motive was extracted unit patterns and the original pattern was restored using Adobe Illustrator. Restored patterns were restructured to be applied to cultural products fit for contemporary formative sense. Fabrics used in dyeing were cotton, linen, ramie, silk, and polyester. Although the same persimmon dyeing was applied, we produced different feelings of patterns using various fabrics and in some cases gold and silver powder was added for the effect of gloss in addition to the embossing of patterns. Using printed fabrics we manufactured tea pads, place mats, cushions, wrapping cloth for gifts, wallet, lampshades.

  • Patterns in clothing symbolize some specific meaning that differs across cultures and religions, although patterns have been mostly used to realize human desires to overcome natural hazards in every culture or religion. This research aims to compare animal patterns of Korea (Confucian/Buddhism culture) with those of Byzantine (Christian culture), based upon a research method of literature survey. It is found through the research that both cultures used common patterns, such as dragon, butterfly, bat, honeybee, peacock, fish, and chicken. In the case of dragon patterns, Korea used it to symbolize emperor, dignity, or authority, while Byzantine used it for devil. Bat patterns had different symbolic meanings in both cultures: they mean happiness, longevity, prosperity or many off-springs in Korea while they mean misfortune or unhappiness in Byzantine. On the other hand, the rest of animal patterns, including butterfly, honeybee, peacock, chicken, had quite a similar symbolic meaning. Butterfly means change of life or beginning of new life in Korea, whereas it means resurrection in Byzantine. Honeybee symbolizes diligence, order, and cooperation. Many animal patterns were used in both cultures at the same time. Another difference can be found in terms of the kind of animals; for example, Korea used wild goose, pheasant, giraffe, deer, mandarin duck & turtle, while Byzantine used eagle, snake, pigeon. Of course, each and every animal has its own meaning, mostly positive. Except dragons and bats, both cultures have a similar meaning in most of animal patterns. Generally speaking, Korea used imaginary animals to pray for human happiness, but Byzantine used real animals to pray for resurrections.

A Study on the Aesthetics of Women's Body in the Chinese Republican Period -Focused on Women's Magazines, Funüzazhi & Linglong- (민국시기 중국 여성들의 인체미 의식에 대한 연구 -푸뉘자즈(부녀잡지(婦女雜誌))와 링롱(영롱(玲瓏))을 중심으로-)

  • The Republican Period of China (1912 to 1949) was when the archetypes of thought (constituting contemporary China) engaged in heated rivalry and were directly influenced by Korea through frequent exchanges. This study analyzes the characteristic of Chinese women's aesthetics towards the human body with a focus on visual materials (such as articles and illustrations concerning hairstyle, makeup, skincare, fashion, and gymnastics) featured in the Chinese women magazines of Fun$\ddot{u}$zazhi (婦女雜誌) and Linglong (玲瓏). This study analyzes these magazines and compares them with Korean counterparts. The movement of the developed and controlled human body was a common characteristic of this period; however, compared to the Chinese, the Japanese colonial period of Korea resulted in an introspective self-examination through excessively objectified eyes. Dress and adornment as the symbol of a new civilization acted as the most remarkable signifier. The overlapping of a western image with a Japanese image led to more resistance in Korea. The criterion for the value of a women's external appearance (that traditionally dualized womanly virtues) collapsed and dress was accepted as an expression of individuality instead of as a social class. The human body was traditionally recognized as a microcosm of the universe that dominated the natural principle of Yin-Yang and the Five Elements. However, the ideal human body was postulated and the aesthetic consciousness of the body changed into an imaginary view of the human body that proceeded to keep the body fit for and gave birth to the concept of supplementing the deficiency of the beauty of the human body with dress and makeup.
