Clothing design is one of design products for human, the end user and corresponds to artifacts. Sometimes artifacts with one mono module exist, and so does artifacts assembled and combined with multi modules of same shape and size or various shapes and sizes and thus all design products can be understood by modularity concept. The purpose of this study was to make a new suggestion for the clothing design and production of high uniqueness and creativity by reviewing and synthesizing the foundation of clothing modularity concept as the original clothing design figures from the history have shown various modularity concept evolution from mono module to multi module stages. The methods of this study were to identify clothing modularity and analyze the type, evolving direction, and category of clothing modularity, and the value of clothing modularization design through comprehensive literature reviews on topic-related books and theses. The original clothing figures with Significance from the clothing history were analyzed in evolution sequence for application direction and value of clothing modularity in flat pattern. Clothing modularity in ancient clothing figures was classified as three types of the fixed, drapery, and straight lined in evolving direction from clothing of mono module to flat patterned clothing. The direction of clothing modularity was identified as mono- dual-triple-multi into another level of multi modularity after intentional devolution. The categorization of clothing modularity was identified in terms of clothing flat construction, clothing design construction, and clothing form modeling. The value of clothing modularization design using clothing modularity was identified as economical efficiency, convenience, promptitude, adaptability, functionality, and creativity.

데니스 게이버(Dennis Gabor)의 음향 양자(Acoustic Quanta) 이론은 음향 합성법의 하나인 그래뉼러 합성법(Granular Synthesis)의 이론적 토대가 되어 많은 컴퓨터 음악 작곡가들과 사운드 디자이너들에게 영감을 주었다. 음향 양자는 1에서 100 ms의 지속시간을 가진, 시간적으로 더 이상 짧게 분해될 수 없는 소리를 뜻한다. 그래뉼러 합성법은 원음을 매우 짧은 시간 간격으로 분할하여 소리 입자들(Sound Grain)로 만든 다음, 이 소리 입자들을 조합하여 새로운 음악 또는 음색을 구현하는 방법이다. 음향 양자 개념은 그래뉼러 합성법의 소재가 되는 소리 입자의 이론적 근거가 되었다. 기존 음향 합성법과는 전혀 다른 음색의 사운드를 만들어 낼 수 있는 그래뉼러 합성법은 사운드 디자인 분야에서 다양한 용도로 사용 가능하다. 본 논문에서는 게이버의 음향 양자 개념을 소개하고 이를 그래뉼러 합성법에 적용하여 활용 가능한 사운드 디자인 방법, 특히 동기식(Synchronous) 그래뉼러 방식에 의한 신디사이저(Synthesizer) 제작 가능성과 그 응용에 대하여 논하였다. 연구결과 가청주파수를 감안한 음향 양자의 지속시간은 0.239에서 33.367 ms 사이가 되어야하기 때문에 음향 양자의 본래 개념과는 차이가 있었다.

우리나라의 자동차 산업은 최초의 고유모델 포니 이후 25년의 시간동안 빠른 성장을 보이며 많은 고유모델 차량을 개발하였다. 초기에는 외부 디자이너에게 의존하는 형태에서 시작되었으나, 점차로 기술개발의 독자성을 확보하게 되어, 다양한 차종의 고유모델을 개발하게 되었으며, 품질도 향상되어 자동차는 우리나라의 주요 수출품목이 되었다. 외부 디자이너에 의하여 시작된 고유모델 디자인이 점차로 우리나라만의 독자성을 가지는 디자인으로 탈바꿈되는 과정 속에 있는 것이 최근의 경향이라고 할 수 있다. 초기에서부터 개발되어온 고유모델 차량의 차체 조형 개념은 크게 네 가지 유형으로 나누어 분석할 수 있는데, 이들의 유형은 각기의 특성과 성격을 가지고 있다. 우리나라의 고유모델 차량 개발 과정은 도입기, 정착기, 발전기, 그리고 성숙기로 나누어 볼 수 있는데, 각 시기에 개발된 차종은 디자인 주체, 그 시기의 국내 기술여건, 시장 상황 등을 반영하여 다양한 조형 양식을 보여주고 있다. 그런데 이들 조형 양식은 발전기와 성숙기를 거치면서 두 가지의 유형으로 압축되고 있다. 이러한 경향은 기술개발에 의한 요인이 크겠지만, 시장에서의 소비자들의 성향을 반영한 것 역시 큰 요인으로 분석된다. 향후의 고유모델 개발에서는 이러한 조형성의 특징 변화를 보다 명확히 인식하고, 독자적인 지향성을 가지는 차체 조형 개념에 의한 작업이 이루어져야 한다.

Objectives : This study aims to examine the multi-layered meanings of Li Dongyuan's concept of 'internal damage' through examining the origins of the 'internal damage' concept together with discussions derived from his 'Differentiation of Internal and External Damage'. Methods : Rather than Li's original works, those done by later doctors who were influenced by Li were thoroughly examined in this study to determine the relationships among internal and external damage, and external contraction. Results : Based on discussions related to the 'differentiation of internal and external damage' following Li, his concept of 'internal damage' could be understood as multi-layered, as it contains both spatial as well as pathogenic meaning. Therefore the meaning behind categorizations of internal and external damage, and internal damage and external contraction could be different. Li's 'internal damage' concept includes not only internal pathogen but elements of external contraction of wind and cold, which seems to have been integrated into the 'Cold Damage Theory' after Zhu Danxi, seemingly having changed the concept of cold damage. Therefore, discussions on the crossing between internal damage and external contraction have on one hand expanded the boundaries of each concept, while on the other hand, have caused confusion between the two at times. Conclusions : The concept of 'internal damage' has been widely accepted due to Li Dongyuan, on which related discussions have been centered. However, the concept was originally multi-layered, naturally leading to various discussions. Future studies should focus on the relationship of 'internal damage' with 'external damage' or 'external contraction', beyond the theories of Li.

Concept development of a real-time Field Programmable Gate Array (FPGA)-based switched Ethernet data communication network for the Man-Machine Interface System (MMIS) is presented in this paper. The proposed design discussed in this research is based on the systems engineering (SE) approach. The design methodology is effectively developed by defining the concept development stage of the life-cycle model consisting of three successive phases, which are developed and discussed: needs analysis; concept exploration; and concept definition. This life-cycle model is used to develop an FPGA-based time-triggered Ethernet (TTE) switched data communication network for the non-safety division of MMIS system to provide real-time data transfer from the safety control systems to the non-safety division of MMIS and between the non-safety systems including control, monitoring, and information display systems. The original IEEE standard 802.3 Ethernet networks were not typically designed or implemented for providing real-time data transmission, however implementing a network that provides both real-time and on-demand data transmission is achievable using the real-time Ethernet technology. To develop the design effectively, context diagrams are implied. Conformance to the stakeholders needs, system requirements, and relevant codes and standards together with utilizing the TTE technology are used to analyze, synthesize, and develop the MMIS non-safety data communication network of the APR1400 nuclear power plant.

F. L. Wright was, from his early days, influenced by Japanese Culture and endeavored his original concept of orgonic orchitecture. In his 1st Golden Age, he devoted to establish an architectural concept of Organism which was proved by the theories of New Science and also had been universal in ancient Orient. Later, in his 2nd Golden Age, he tried to embody his unique concept in prairie houses and office buildings. The organic structure and spatial unit that actually applied to these works, were good examples of realization of the simplicity and continuity which he found out in Japanese culture. This paper is to study on the influence of Japanese culture on a course of Wright's embodying his organic architecture, and to study on a way of its realization in his works. To be concrete, main contents of the study are as follows; 1) the relationship between Wright's integrate perception and the orientalism 2) the influence of the traditional Japanese painting like woodblock prints and the aesthetic theory of the traditional Japanese pictorial art on Wright's design principles 3) the influence of Wright's experiences in Japan on his design principles 4) the influence of Wright's analysis of the traditional Japanese dwelling on his design principles 5) the course of Wright's embodying his organic architecture concept, and the way of its realization in his works.

Few instruments are available to measure nurses' perceptions of cultural competence in South Korea. Furthermore, the equivalence of factors between original and translated instruments has not been evaluated. The specific aims of this study were to identify the validity and reliability of a Korean version of the Cultural Awareness Scale (K-CAS) and to evaluate the equivalence of factors between the original CAS and the K-CAS. A total of 515 nursing students completed the 26-item K-CAS, 28-item Caffrey Cultural Competence in Healthcare Scale (CCCHS), and eight-item Openness to Diversity and Challenge Scale (ODCS). The K-CAS exhibited good reliability (${\alpha}=.83$) and construct validity by correlating with the CCCHS (r=.344, p<.001) and ODCS (r=.394, p<.001). Confirmatory factor analysis results of the K-CAS confirmed the same factor structure as the original CAS. The K-CAS could be a useful tool to assess the concept of cultural competence among nursing students and nurses.

Combining the concept of self-certified public key and message recovery, Li-Zhang-Zhu (LZZ) gives the proxy signature scheme with message recovery using self-certified public key. The security of the proposed scheme is based on the discrete logarithm problem (DLP) and one-way hash function (OWHF). Their scheme accomplishes the tasks of public key verification, proxy signature verification, and message recovery in a logically single step. In addition, their scheme satisfies all properties of strong proxy signature and does not use secure channel in the communication between the original signer and the proxy signer. In this paper, it is shown that in their signature scheme a malicious signer can cheat the system authority (SA), by obtaining a proxy signature key without the permission of the original signer. At the same time malicious original signer can also cheat the SA, he can also obtain a proxy signature key without the permission of the proxy signer. An improved signature scheme is being proposed, which involves the remedial measures to get rid of security flaws of the LZZ et al.'s. The security and performance analysis shows that the proposed signature scheme is maintaining higher level of security, with little bit of computational complexity.

대규모 데이터 네트워크에서 최적 경로 설정 문제를 해결하기 위해 HAD-GP (hierarchcal aggregation/disaggregation and decomposition/composition gradient projection) 알고리즘이 제안된다. 이를 위해 우선 [7]에서 제안된 IAD-GP (interative aggregation/disaggregation GP) 알고리즘의 성능을 향상시킨다. 원래의 IAD-GP 알고리즘과 변형된 IAD-GP 알고리즘에서 사용된 A/D 개념은 본질적으로 대규모 데이터 네트워크의 계층적 구조에 적합하기 때문에 알고리즘의 수렴에 있어 속도 향상을 기대할 수 있다. 제안된 HAD-GP 알고리즘 역시 대규모 데이터 네트워크의 계층 구조화된 토폴로지를 이용하여, 특히 분산화된 환경하에서 수렴속도의 현저한 향상을 달성할 수 있다. 이 속도 향상 효과는 컴퓨터 모의실험에 의해 HAD-GP 알고리즘을 IAD-GP와 일반적인 GP (ORD GP) 알고리즘과 비교함으로써 보여진다.

논문에서는 워터마크 추출 후 원본 이미지를 복원할 수 있는 리버서블 워터마킹 알고리즘을 제안한다. 대부분의 워터마킹 기법에서는 정보 삽입 때문에 원본 이미지에 열화를 발생시키지만 본 알고리즘은 워터마크 추출 후 워터마크가 삽입된 이미지로부터 열화를 제거하여 원본 이미지를 복원시킨다. 제안한 알고리즘에서는 히스토그램 쉬프팅과 로케이션 맵 구조를 이용한다. 로케이션 맵을 이용함으로써 플립 현상을 제거하고 반복적인 정보 삽입을 통해 정보 삽입량을 크게 증가시킬 수 있었다. 실험 결과 최대 120k bits의 높은 정보 삽입량을 보이면서도 평균 41dB 이상의 우수한 비가시성을 보임을 확인하였다.
