This study has attempted to investigate the effect of cubism on fashion and figure out how its formative characteristics have been expressed in contemporary fashion in the 21st century, focusing on the period since 2010. The propose of the study is to broaden research scope in fashion design through analysis and inspection on formative aspects among the cases which have proposed brand - new fashion designs by adapting cubism in fashion. To find out the characteristics of cubism in painting and formative characteristics of contemporary fashion in which the characteristics of cubism are reflected, a literature review has been conducted by referring to domestic and foreign books, previous papers, academic journals and Internet resources on cubism. For an empirical study, in addition, photos of cubism-applied modern fashion have been collected and analyzed through http://www. samsungdesign.net. The following results have been obtained: First, the formative characteristics of cubism were obtained in following categories; character of figure, simultaneity, reiteration and facticity. Second, according to analysis on cases after applying the formative characteristics on contemporary fashion design, the character of figure by the geometric shape of cubism was observed in fashion as well. After dismantling and reconfiguring garments, simultaneity has been expressed in an exaggerated and distorted manner through regular and repetitive overlapping or overlapping of irregular shapes. In terms of facticity, novelty has been delivered with the use of heterogeneous materials, using collage and patchwork techniques. Third, simplicity and functionality in cubism - style garments in the early 20th century have disappeared in contemporary design in the 21st century. Now, a dynamic aspect is only found. Fourth, unlike common paintings, 2D textiles are added to a 3D body in fashion design. In addition, it can be observed from multiple angles depending on the movement so that it can display more diverse shapes. Therefore, it could be the origin of inspiration to many designers.

Rail provides running tract for train and broadly and widely conveys the weight of the train exerted from the train wheels that the rail directly supports onto the cross tie and roadbed, and supports the cross-sectional pressure exerted by centrifugal force at curvatures. That is, stationary rail provides surface on which dynamic train runs and guarantees cross-sectional resistance to enable the vertical snake motion of the train wheels as well as to maintain lateral force at curvatures. Rail provides running surface on which train wheels can run smoothly, and secures vertical and lateral force. However, it undergoes continuous destructive reactions (wearing and damages) and abrasion of the cladding by the train wheels. It is obvious that wearing will result when two metal parts act against each other. However, occurrence of abnormal wearing such as rapid wearing of the rail side due to complex generation of various mechanisms at the contact surface between the rail and train wheel flange. It is not easy to simply examine the causes of occurrence of abnormal wearing of rail and train wheel flange. Although countless number of academicians and specialists are conducting researches on abnormal wearing of rail and vertical wearing of train wheels, I believe it is too early to argue on pros and cons due to insufficiency of officially verified information on the issue. This review will be focusing on the examples of repairs that reduced the generation of abnormal wearing of rail by reviewing and improving characteristics of wearing and slack, speed of the train and cant as well as status of lubricator by choosing the compound curves present in the section between the $Anguk{\sim}Jongno3-ga$ Stations of the Route No. 3 among the compound curve tracks of the Seoul Metro Routes No. 3 & 4 at which abnormal wearing is generated continuously.

Based on monitoring data collected from the Nanjing Dashengguan Bridge over the last five years, this paper systematically investigates the effects of temperature field and train loadings on the structural responses of this long-span high-speed railway bridge, and establishes the early warning thresholds for various structural responses. Then, some lessons drawn from the structural health monitoring system of this bridge are summarized. The main context includes: (1) Polynomial regression models are established for monitoring temperature effects on modal frequencies of the main girder and hangers, longitudinal displacements of the bearings, and static strains of the truss members; (2) The correlation between structural vibration accelerations and train speeds is investigated, focusing on the resonance characteristics of the bridge at the specific train speeds; (3) With regard to various static and dynamic responses of the bridge, early warning thresholds are established by using mean control chart analysis and probabilistic analysis; (4) Two lessons are drawn from the experiences in the bridge operation, which involves the lacks of the health monitoring for telescopic devices on the beam-end and bolt fractures in key members of the main truss.

본 논문에서는 대상테의 움직임이 합성구경 기법에 미치는 영향을 조사하고, 이를 토대로 합성구경 기법의 움직임 긱함을 극복할 수 있는 방법을 제안하였다. 제안한 방법은 일정한 관심영역 내에서 대상테의 대표적인 축방향 움직임을 추정하고 이에 의한 집속 지연 오타만을 관심영역의 모든 영상점에 대하여 동일하게 보상하는 영역 기반의 움직임 보상 기법을 사용한다. 이때 대표 움직임은 관심영역 내에서 접속된 신호의 에너지가 최대가 되는 점에서의 움직임을 상호상관을 이용하여 계산할 수 있다. 또한 자기상관 기반의 도플러 평균 주파수 추정 기법을 이용하여 관심영역 내의 대표적인 축방향 움직임(대표 움직임 속도)을 추정하는 방법을 제안하였다. 모의 실험과 실제 인체 실험 결과 두 방법 모두 합성구경 영상의 움직임 오류를 제거함으로써 양방향 동적접속의 구현을 가능하게 하여 초음파 영상의 해상도 및 SNR을 현저히 개선시킬 수 있음을 확인하였다. 또한 자기상관 방법은 훨씬 적은 계산량으로 상호상관 방법과 거의 동일한 성능을 제공함을 확인하였다.

한국은 오래전부터 '고양이 앙화'에 대한 선입견으로 고양이를 많이 꺼리는 문화였지만 근래 들어 반려동물로 고양이가 증가하고 고양이 소재로 그림책과 에세이, 웹툰 등이 국내 독자에게 많은 관심을 받고 있다. 사노 요코 그림책을 살펴보았을 때 국내 출판된 그림책의 약 50%가 고양이를 소재로 한 그림책이며 이중 '100만 번 산 고양이'는 전 세계적으로 밀리언셀러이다. 연구방법은 사노 요코 그림책에 표현된 고양이 캐릭터가 그림책 스토리 주인공 외에 다른 상징적 의미가 있는가? 를 중심으로 국내 번역 출판된 작가의 고양이 캐릭터 그림책 5권을 사례로 분석하였으며 결과로 도출된 그림책의 고양이 캐릭터 성격 및 상징적 의미와 표현기법을 이미지와 함께 제시하였다. 연구 결과로 사노는 고양이를 통해서 고양이가 고양이듯 우리 자신의 '자유의지'를 존중하며 사랑할 것을 그림책에 담고 있다. 결론으로 그림책에서 고양이 캐릭터의 상징적 의미는 대부분 작가자신이고 때로는 아들과 엄마로 상징됨을 알 수 있었다. 공통으로 사용된 캐릭터 색과 유사한 짙은 윤곽선은 온유한 캐릭터와 때로는 독선적인 강한 성격 그리고 정적이거나 동적인 움직임을 극화시키고 있다.

In the solid freeform fabrication (SFF) system using selective laser sintering (SLS), polyamide-12 powder is currently recognized as general material. In this study, some kinds of polyamide-6 powders with different shape and particlesize were fabricated to investigate the formability, the microstructure and mechanical properties. Also, to develop a more elaborate and rapid system, this study employs a new SLS device with a 3-axis dynamic focusing scanner system instead of the existing fe lens used in commercial SLS. Polyamide-6 powders having the average size of 100 m were treated thermally in order to keep the spherical symmetry in shape. These polyamide-6 powders were mixed with polyamide-12 powders having the average size of 50 m to give the bimodal distribution of size. These mixed powders showed the better fabrication in the selective laser sintering process because the smaller particles of polyamide-11 played an important role in the compact packing of powders by filling the void space between the large particles of polyamide-6. Also, Experiments have performed to evaluate the effect of a scanning path and sintering parameters by fabricating the various 3D objects.

This paper investigated the teaching and teaming of contents-related graphing in Korean secondary textbooks and suggested the improved methods of graph instruction through this analysis. reification-the case of function, In Harel, G., Dubinsky(Eds.), The Concept of Function : Aspects of Epistemology and Pedagogy Textbooks are analyzed from the viewpoint of the proportion of graphing contents, their sequencing, the proportion of each domain in graphing activities (interpretation vs. construction, quantitative vs. qualitative aspect, local vs. global aspect) and tasks (prediction, translation, scaling), and the difference in the graphing contents between the sixth and the seventh curriculum. This analysis demonstrates that graphing contents are increasing in textbooks, therefore the high school textbooks appear in almost every content area. The graphing activities concentrate on the construction, the quantitative aspects, and the local aspects, and are gradually focusing on the interpretation and global aspects of high school textbooks. Furthermore, most of graphing tasks favor translation. In contrast, the current seventh curriculum includes a balance of interpretation and construction activities and has more global aspects than the sixth curriculum based textbooks; however, the qualitative approach still rarely appears. For the graphing tasks, translation is still prevalent, but the importances of prediction tasks based on graph have increased in comparison with the sixth curriculum textbooks. Further, the seventh curriculum based textbooks are designed to stimulate more dynamic graphing instruction by introducing new tools such as graphing calculators and computer software. We suggest that the qualitative and global aspects should be emphasized in early graph instruction, a variety of graph activities in realistic contexts should be performed, and educational technology such as graphing calculator and computer can be efficient to implement these ideas.

화성(華城) 연쇄 살인 사건은 공간적, 시간적으로도 현재의 화성시 뿐만 아니라 화성시의 일부인 동탄 신도시와도 관련성이 크지 않다는 리얼리티(reality)에도 불구하고, 대중매체의 선정성으로 인해 사람들은 화성시를 부정적인 지역 이미지(image)를 가진 도시로 인식하게 되었다. 본 연구에서는 화성시의 부정적인 지역 이미지가 영화와 신문기사 등을 통해 어떻게 형성되었는지를 살펴본 후, 동탄 신도시에 거주하는 주민들과 학생들이 이러한 부정적인 지역 이미지를 어떻게 생각하고 있는 지를 주민 인터뷰와 학생들을 대상으로 한 멘탈맵(mental map)의 작성 등을 통해 탐색해 보았다. 이를 통해 장소에 내재된 도시의 부정적인 이미지에 대한 반발로 인해 표출되고 있는 화성시민으로 사는 것과 동탄 신도시 주민으로서 사는 것 사이의 지역 정체성(identity)의 혼란, 살인이라는 무서운 범죄의 장소로서의 상징적 의미와 역동적으로 발전하는 장소로서의 공간적 의미가 양립되고 있는 동탄 신도시의 장소감과 지역 정체성의 혼란의 양상을 드러내고자 하였다.
