  • 'Headline Database of Newspaper Articles' is a database which contains about 141,500 newspaper articles from 1949 to March, 2009. They are collected from two perspectives; 'language' and 'language life' by KOKKEN. There were 3312 newspaper articles (about 2.34%) which included the word ONNA at 'Headline Database of Newspaper Articles'. The number of newspaper articles related to ONNA started to increase in 1975 but they decreased afterwards. They increased rapidly in 1980 and maintained the condition. However, they started to decrease rapidly in 1990 and maintained the decreased condition. They increased rapidly again in 2004 and 2007. The main causes of rapid increase were the commercial message of instant noodles "I am the one who is making. I am the one who is eating." in 1975, newspaper articles related to "Starting of full-scale studies on female language" in 1980, comments of "active women" and "men's crime" related to a murder case of an elementary school student in Sasebo City and mixed attendance books in 2004, a comment of "Women are machines which give birth to babies" in 2007. Those six causes of rapid increase suggested that the perception of gender such as 'Men need to work outside and Women need to do housework and take care of child' which was fixed until then was changing and becoming a stereotype of virtual reality rather than reality. The vocabulary related to ONNA appeared 3411 times among 3312 newspaper articles which included ONNA. Typical forms of the vocabulary related to ONNA were and . They appeared 2390 times and occupied 70% of the whole data. (3411 times) The form of ONNANOKO among the vocabulary related to ONNA appeared 113 times and occupied a high rate. ONNANOKO(113) and other words such as SHOJO(115), JOJI(28), YOJO(9) (152 in total) implied that appearing of young women at newspaper articles were increasing. Also, the vocabulary related to 'female language' such as ONNAKOTOBA(28) ONNANOKOTOBA(10) and a woman's heart such as ONNAGOKORO(35) and ONNANOKIMOCHI(34) appeared frequently. The vocabulary related to JOSEI were divided into <$JOSEI^{**}$> and <$^{**}JOSEI$>. <$JOSEI^{**}$> were mainly related to an occupation. <$^{**}JOSEI$> were mainly used to express women by regional groups such as or combined with modifiers to express women such as . In case with modifiers, WAKAIJOSEI appeared 35 times and showed the highest frequency. It had negative evaluations in many cases. The vocabulary related to JOSI appeared on the form of <$JOSI^{**}$> and mainly associated with 'a girl's school' and 'a female student'.

  • 본고에서는 음양가(陰陽家)의 등장 과정과 아울러 묵가(墨家)의 음양오행론(陰陽五行論)을 제가(諸家)와의 비교를 통해서 살펴보았다. 사마천(司馬遷)이 열전(列傳)에서 시사한 바대로 추연(鄒衍)으로 대표되는 음양가는 당시 유가(儒家)와도 일정한 관련이 있었던 것으로 보인다. 음양 관념은 본래 햇빛과 관련이 있었지만 전국 중기 이후 기(氣), 혹은 도(道) 관념과 연계되면서 점점 추상화되었다. 오행 관념 또한 본래 일상생활에 필수적인 오재(五材) 관념에서 출발하여 인간과 자연의 모든 것을 포괄하는 분류 기준으로 발전하였다. 오덕종시설(五德終始說)로 대표되는 추연을 비롯한 음양가 혹은 음양오행가의 사상은 근본적으로 왕조 교체의 법칙성을 도출하기 위한 것이었다. 그러나 이러한 관점은 전국말에 이르기까지 백가쟁명의 주제로서 부각되지 못하였다. 비록 제가에서 공통적으로 음양오행론에 대한 기본적인 이해를 전제로 그것을 활용하고 있는 것은 사실이지만 각각의 사상체계에 연계되지 못하였다. 묵가 또한 음양오행 관념을 수용하고 군사학 방면에 활용하면서도 일관되게 합리적인 관점을 유지하고 있다. 이것은 제가의 현실인식과 역사관의 차이에서 근본적인 원인을 찾을 수 있을 것이다.

  • Soils are generally classified as fine-grained or coarse-grained depending on the percentage content of the primary constituents. In reality, soils are actually made up of mixed and composite constituents. Soils primarily classified as fine-grained, still consists of a range of coarse particles as secondary constituents in between 0% to 50%. A laboratory scale model test was conducted to investigate the influence of coarse particles on the physical (e.g., density, water content, and void ratio) and mechanical (e.g., quick undrained shear strength) properties of primarily classified fine-grained cohesive soils. Pure kaolinite clay and sand-mixed kaolinite soil (e.g., sand content: 10%, 20%, and 30%) having various water contents (60%, 65%, and 70%) were preconsolidated at different stress levels (0, 13, 17.5, 22 kPa). The quick undrained shear strength properties were determined using the conventional Static Cone Penetration Test (SCPT) method and the new Fall Cone Test (FCT) method. The corresponding void ratios and densities with respect to the quick undrained shear strength were also observed. Correlations of the physical properties and quick undrained shear strengths derived from the SCPT and FCT were also established. Comparison of results showed a significant relationship between the two methods. From the results of FCT and SCPT, there is a decreasing trend of quick undrained shear strength, strength increase ratio ($S_u/P_o$), and void ratio (e) as the sand content is increased. The quick undrained shear strength generally decreases with increased water content. For the same water content, increasing the sand content resulted to a decrease in quick undrained shear strength due to reduced adhesion, and also, resulted to an increase in density. Similarly, it is observed that the change in density is distinctively noticeable at sand content greater than 20%. However, for sand content lower than 10%, there is minimal change in density with respect to water content. In general, the results showed a decrease in quick undrained shear strength for soils with higher amounts of sand content. Therefore, as the soil adhesion is reduced, the cone penetration resistances of the FCT and SCPT reflects internal friction and density of sand in the total shear strength.

  • Immersive space is a new type of space, which is converged with other domains and expressed in various ways and here, a mutual exchange between space and participants is realized with active intervention of participants. The purpose of this study is to examine boundary changes and characteristics in virtual space and reality or inside and outside, focusing on immersive space. For this study, a case analysis was conducted, based on the key words regarding flow experience and boundary characteristics in immersive space. The boundary characteristics extracted are as follow. First, while immersive space is overlapped in many different ways, the boundary in space gradually changes and one unique and convergent space is formed. Also, a combination of overlap is made with internal and external physical force and a convergent boundary is created. Second, forms are mixed in diverse ways and an unrealistic boundary space is revealed. For new experience, it has familiar, but new experiential characteristics and also shows an expanded boundary by the medium of different domains. Third, a simultaneous space, based on variability of time and space, has an ambiguous boundary due to a meaningless physical boundary of space and changing into a space region constantly, it becomes an unlimited variable space. Fourth, a linear expansion-based emergent space has nonlinearity, which creates a meaningless boundary, recognized as an irregular, dynamic and transformative space and expands to a creative space. In conclusion, it is anticipated that based on diverse characteristics found in immersive space, this study would give unlimited inspiration to many design fields and art creation activities and contribute to a further development through continued research on immersive space.

  • Our time is called as the era of information-oriented society and up-to-date scientific technology, but it can be also called as the era of image. It is because the image has much influence upon our everyday life. In the deluge of images, the delivery of image Is a better and faster synergic tool than the delivery of language, and this trend is consistent with the phases of the times in which the analog modality of synergy is converted into the digital one. The image is a picture that is formed by a physical process, and is all the figures reflected by electronic equipments that reproduce the image. After the discovery of photograph in 1893, the image has been appeared first with the form of movie, and then with the form of TV. However, the appearance of such unidirectional synergic tools as movies and TV. has provided artists with some creative motives with which they intercommunicate their messages via some experimental bidirectional synergic tools. Among image-media arts, the performance of installation and participation is an important example that causes many changes through conceptional conversion, such as the conception of the time in space and formative characteristics. What satisfy this trend have been videos, lasers, holographic, and etc. Furthermore, the appearance of computer has provided a synesthesia, that is, a virtual reality, and mixed a real image with a visional one. The image-media art will realize better synergy through combining brand new machines, informational technology, and art, and have much influence upon our everyday life formatively and artistically in the future. with this study, through analyzing the meaning of relationship between image equipments and space.

  • The underlying purpose of this paper is to interest scholars in 'Trade English'. 'Trade English' has to be recognized as one area of 'International Trade' disciplines and more studies have to be carried out with more attention from the scholars. Although there are many areas to be dealt with in 'Trade English', this paper discusses about the syllabus design of 'Trade English' from an educator's point of view. First of all, this paper reviews some theoretical background researches about needs analysis and syllabus design in 'Trade English' teaching and learning as ESP. With a systematic structure under the decent syllabus, selection and sequence of contents get clear and easier. Secondly, along with the rationals based on theoretical researches, how these theories are being or can be applied to the real classroom are discussed for further studies. A different syllabus would be designed according to needs analysis. In reality, the syllabus for practitioners who are doing their jobs in International Trade areas has to be definitely different from the one for pre-practitioners who are studying in International Trade areas at the tertiary education level. Namely, different learners present different needs and different needs make up the different syllabus. In order to provide these learners with the syllabus which can address their own needs, more researches or studies have to be done in the future. Since 'Trade English' is the discipline where two areas-International Trade and English as a second/foreign language-are mixed, the researches or studies also have to be carried out collaboratively by scholars from both areas.

  • This research explores the idea of digilog for fashion; it would help to conclude the uncertain mixed-phenomena and words as a neologism and find a fundamental concept that would be a reference for a lot of uncertain new words that have been occurring even this year. Furthermore, this research is aimed at analyzing how digilog has been reflected on the contemporary fashion and directing the ways towards the future of fashion. The digilog fashion design is the expression of a combination of opposite extremes, that is to say the combination of a paradoxical mix and directly-opposed elements. The outward expression of fashion design with digilog can be classified into several ways. First of all, it tends to use the elements of paradoxical expression; for example, applying high-technology to express a primitive and natural material. The analog expresses unprocessed. Secondly, using high-tech machine to express the texture of handicraft or rough embroidery. Lastly, digital printing(DTP) is applied to enlarge the several or the whole parts of a natural object or sensitivity. As a result of the analysis, the inside view of the contemporary fashion with digilog delineate followings; it is the attitude that claims to go back to the past and accepts the combination of nature and high-technology to get calmness in the rapidly changing modern world. And it is the will to fly from the utterly exhausted reality through the recurrence of the past when there used to be a lot of energies and used to live in affluence.
