  • 소수는 자연수와의 유사성 덕분에 교수-학습시 용이함과 곤란함을 동시에 지니는 초등 수학의 지도 내용이다. 소수의 창시자로 언급되는 Stevin과 소수 개념을 소개한 그의 저서 '소수(La Disme)'는 소수의 역사에서 빼놓을 수 없는 수학자이고 수학책이다. 그러나 대부분의 수학적 개념들의 발달 과정과 마찬가지로 소수 개념에 대한 인식 및 사용은 Stevin 이전 시대에 이미 있어 왔다. 본 연구에서는 그럼에도 불구하고 Stevin이 소수의 창시자로 언급되는 이유를 '소수'가 수학사에서 지니는 의미와 관련하여 고찰하였다. 구체적으로 표기적 측면, 책의 전개 방식, 개념적 혁명, 실용적 목적 등의 측면에서 의의를 찾을 수 있었다. 그리고 책의 명성에 비해 원전의 상세한 내용은 잘 알려져 있지 않은 <소수>에 대한 상세한 검토를 통해 초등수학교육에서 소수가 지도되는 방법과 관련한 몇 가지 시사점을 논의하였다.

  • During the past few years, various traffic-flow forecasting models, i.e. an ARIMA, an ANN, and so on, have been developed to predict more accurate traffic flow. However, these models analyze historical data in an attempt to predict future value of a variable of interest. They make use of the following basic strategy. Past data are analyzed in order to identify a pattern that can be used to describe them. Then this pattern is extrapolated, or extended, into the future in order to make forecasts. This strategy rests on the assumption that the pattern that has been identified will continue into the future. So ARIMA or ANN models with its traditional architecture cannot be expected to give good predictions unless this assumption is valid; The statistical models in particular, the time series models are deficient in the sense that they merely extrapolate past patterns in the data without reflecting the expected irregular and infrequent future events Also forecasting power of a single model is limited to its accurate. In this paper, we compared with an ANN model and ARIMA model and tried to combine an ARIMA model and ANN model for obtaining a better forecasting performance. In addition to combining two models, we also introduced judgmental adjustment technique. Our approach can improve the forecasting power in traffic flow. To validate our model, we have compared the performance with other models. Finally we prove that the proposed model, i.e. ARIMA + ANN + Judgmental Adjustment, is superior to the other model.

  • The purpose of this study is to research the viewpoint of space practice method through the discussion about social space. The study researched how social practice strategy is unfolded through the understanding about daily life, space manufacture and interaction. As a social practice, space design should adopt the interaction approach method on the basis of social relationship latent in the base of space. As a result of study, the viewpoint of space practice can be summarized into 3 viewpoints as below. First, it is the viewpoint of recognition through the experience meeting daily life. Rural space is the one of experience where daily life and social relationship interact each other. As a delicate sensible experience, it is the recognition of special space detected in the space where daily life occurs. Second, it is the viewpoint of form creation as a media product of society and space. Space is a whole creature of the relationship that has been formed socially as a historical process. Depending on the goal of community, new form is created by sharing the characteristic of space and having sense of kinship. Third, it is the viewpoint of tuning as a practice for subject participation. Rural space is the daily space to practice structured society subjectively through interaction. In the place of subjective life, there should a space practice with the tuning and cooperation method between subject and society. The main vein of space practice, which is analyzed with the discussion about social space, shows that out lives are maintained by space practice and directly connected to social relationship and structure. After all, the space, which is searched for through space design, has a clear subjectivity, ensures abundant subject life and is led to realization of community value.

  • <콜드 케이스>는 미제 살인 사건을 수사하는 미국 필라델피아 강력반의 이야기를 그리는 미국 TV시리즈이다. 시리즈는 여타의 인기 있는 시리즈들과 달리, 과거와 현재의 시간을 오가며 미국 역사의 소수자, 주류 역사에서 지워진 보통의 범죄 희생자들을 주인공으로 한다. 이유는 시리즈의 목표가 과거의 용기 있는 이들의 헌신으로 이루어진 사회적, 정치적 변화에 대하여 현재의 우리들이 미처 기억하지 못한 부분들을 다시 한 번 돌아보게 해주는 것이기 때문이다. 시리즈는 플래시 백 기법, 영혼의 등장, 시대배경과 주제에 정확하게 부합되는 대중음악의 사용을 통해 시청자들의 감정적 몰입을 유도하고, 간접경험으로만 기억하고 있는 역사적 사건들의 숨은 주인공들을 기억하게 한다. 즉, 기존의 기억만으로는 부족한 부분을 좀 더 세밀하게 보완한 "보철적 기억"의 개념으로 시리즈 존재의 가치를 입증한다. 우월한 지식과 권력의 남용으로 구성한 사회적 구조의 변화는 개인들의 끝없는 노력을 통해서만이 가능했고, 절대 그들을 잊어서는 안된다는 것이 시리즈 전체의 이야기 이다.

  • The term 'modern', in broader sense, refers to the concepts like modernity, modernization, modernism and the like, which came from Westernization impling the recognition of indigenous culture as being inferior to Western culture by comparison along with the expanded influences of the Empire of Japan. These concepts, however, rather than evolving from Western standards, came into being as a form of civilization led by Japan which had already tasted the fruits of modernization by 1920s. Since 1920s, the policy of, so-called, reconstructing Asian countries by Japan came to create eastern way of modernism, as a new East Asian trend mainly revealed in China which was against colonization after Japan's invasion and conquest of Manchuria. Therefore, Eastern' modern' unlike Western one could be understood in the widespread terminology, 'Modern(摩登)' in Shanghai, reflecting consciousness like 'Fashion' or 'Trend' in female images on a variety of visual media. By 1930s it was the most notable that 'modern' was accepted as something similar with 'Fashion', or 'Trend' in sociocultural contexts. These atmosphere had led commercial arts to enable to communicate with the public in a great deal of supports and success in Shanghai which was widely regarded as the citadel for the inflow of Western culture, among which transformations in female images were remarkable as a representative form of culture. It is also remarkable that 'historical modernity' transforming from the feudal age to modern society was considered a synchronic modernity, and nationalism was regarded as a sort of being modern, while involved in the newly-changed female images as a fashion mode. Changes in fashion including hair style in Shanghai by 1930s, as a way of expressions showing what was modern through commercial artistic productions, were easily noticed in visual media as an outlet of modern women's inner desire revealing their pursuit for new mode of life in metropolitan cities. As a characteristic of the time creating a new code of visual female images, it is notable that there existed another form of 'modern' satisfying socio-cultural needs of the general public seeking for being 'modern'.

  • Gwangju Metropolitan City has implemented a creative regeneration project of Gwangju Folly in the site of Gwangju-eup Fortress as part of the Gwangju Design Biennale by inviting well-known international architects. This study examined and analyzed the characteristics of location, place, and space through actual survey. The results were as follows. Gwangju Folly were mainly located at the four gates and corners of Gwangju-eup Fortress, main entrances of Asia Culture Complex, and historical places where the May 18 Democratization Movement occurred. The common place of Gwangju Folly was a footpath and common location types were the full location of footpath width and the partial location of footpath width. For the spatial types of Gwangju Folly, the practical type which people can stay was the most common(2/3). In the partial location of footpath width, the type which people take a rest and look out over the surroundings accounted for a half. In the full location of footpath width, the gate type which people pass accounted for 2/5. However, as footpath width was minimum for walking, both partial and full occupation types were narrow in place. It influenced the image of Gwangju Folly. Gwangju Folly did not play as a figure and show architects' intentions clearly because of their narrow locations. Therefore, it is very necessary to make a plan to maintain places so that Gwangju Folly do not have a cramped image and architects' intentions become clear with citizens' cultural competence. Also, urban property which creates the identity and attraction of Gwangju continuously should be settled down through helping citizens recognize the intention and value of artistic works.

  • The purpose of this study is to understand the general process from textile design till fashion design and to understand the relation between the body structure by using the x-ray technique. The research method was to see background of the anatomic feature and human skeletal X-ray projection through historical aspect of publications, the Internet, and paper. In terms of production, in order to present a design that takes into account the unique silhouette of the human body without distorting the shape of the human skeleton, X-ray images that were reconstituted using a computer graphic tool (Photoshop CS) were reproduced into the fabric as intense images through the digital Textile Printing technique that is capable of expressing fine and delicate details, and applied into the design. An original design was developed that emphasized the impression of the human body being projected and the shape of the human skeleton realistically expressed in terms of silhouette and detail. The results are as follows: First, Body has a anatomic formative characteristic and its formativeness becomes as a great motive for the artistic expression and thereby it becomes more unique and available for new design expression. Second, Using the 'body frame' as the motive of the research, there's mainly tried to make an unique expression. Third, according to reconstructing human skeletal X-ray projection by using Adobe Photoshop CS2, it can be expressed strong and unique design. Forth, DTP which is being used as an essential technique, expresses the body frame realistically and being used the special type of functional product and silk. Likewise by discovering the diverse formativeness of our body frame and reflecting the sense of humanity into the pieces there's been able to make and develop an unique fashion design. I sincerely hope there is a hug progress in this research in this area.

  • 현재 컴퓨터공학 교육에 참여하고 있는 여학생들의 전공과 일에 대한 가치관을 조사하고 전공 만족도와 유지율을 증진시킬 수 있는 교육 및 평가 과정 개발을 위한 새로운 방안이 필요한 시점이다. 우리 사회에서 컴퓨터공학 기술 분야의 젠더 다양성을 높이고 여성과 컴퓨터공학 기술 분야의 새로운 관계를 모색하는 데 기여하기 위하여 컴퓨터공학 전공 학생들을 대상으로 정량적 및 정성적 조사를 실시한 결과 여학생의 경우 컴퓨터공학 교육 과정을 접하면서 흥미가 감소되고 멘토가 부족하며 자아 존중감이 저하되는 현상이 나타났고 전공과 직업 선택의 연계 과정이 불일치할 수 있어 여성의 이공계 탈출 현상을 초래할 수 있음이 드러났다. 연구 결과 컴퓨터공학 전공 여학생에게 적합한 ICT교육 방법은 지역적, 역사적, 사회적 맥락에 맞게 재설계되어야 하며 컴퓨터공학 전공 여학생들이 갖고 있는 불안감이나 약한 조직 소속감에서 드러나는 특성을 우선적으로 분석하고 이에 맞는 교수법을 제안해야 할 것으로 보인다.

  • The Gamrotenghwa of the Choson Dynasty is a unique genre of buddhist painting in that the destiny of the dead souls and the guidance to nirvana are expressed in reality. More than 50 of the Gamrotenghwa are known to be present, and the lower part of the paintings includes a wide assortment of folk customary scenes reflecting the social life style of the time when the painting was drawn, such as difficulties in life. public life, punishment and war. Changes in the costume of the people shown on the customary scenes of the Gamrotenghwa according to the time based changes in painting style were investigated in this study. The results are summarized in three points. First, the costumes of bureaucrats showed a tendency of preservation without any major changes in the painting. On the other hand, costumes of public and entertainer in the scenes were very close to those worn by the people at that time. The realistic description of public life in the painting may establish the value of the Gamrotenghwa as the historical documents. Second, the costume of the people in the painting showed a dual structure as the social positions; bureaucrats wore various official hats, large coats and belts to expose their social prestige. while the general public wore simple and convenient clothing which is divided into shirt and pants. The dual structure of the costume in the painting is in well accordance with that of the later period of Choson dynasty, suggesting that the customary scenes in the painting represent the social life style of the period. Finally, the customary scenes in the Gamrotenghwa are very variegated. which shows a variety of beauty of wearing even though they look coarse in a sense. The diversity of wearing beauty in the picture may contribute to the recreation of the beauty of shape in the new design of Hanbok.
