Using biometrics to verify a person's identity has several advantages over the present practice of personal identification numbers (PINs) and passwords. To gain maximum security in a verification system using biometrics, the computation of the verification as well as the storing of the biometric pattern has to take place in a smart card. However, there is an open issue of integrating biometrics into a smart card because of its limited resources (processing power and memory space). In this paper, we propose a speaker verification algorithm using a support vector machine (SVM) with a very few features, and implemented it on a 32-bit smart card. The proposed algorithm can reduce the required memory space by a factor of more than 100 and can be executed in real-time. Also, we propose a hardware design for the algorithm on a field-programmable gate array (FPGA)-based platform. Based on the experimental results, our SVM solution can provide superior performance over typical speaker verification solutions. Furthermore, our FPGA-based solution can achieve a speed-up of 50 times over a software-based solution.

스웨덴 국립 디자인 대학은 150여 년의 역사를 가진 세계에서 가장 오래된 디자인 교육기관의 하나로 스칸디나비아 디잔인 발전에 주도적인 역할을 해왔다. 콘스트 팍(Konstfack)이라 불리워 지는 이 학교는 바우하우스의 영향을 받아 근대적인 모습으로 탈바꿈했으며 1970년대에 이르러 오늘날과 같은 실험적인 교과과정과 독특한 교육방식을 완성했다. 이 학교의 상징 엠블 렘에는 'Insight och Flit'라는 말이 새겨져 있는데 이것은 창조적인 직관과 끊임없는 노력을 중시하는 콘스트 팍의 정신을 그대로 표현한 것이라고 할 수 있다. 우리 나라와 스웨덴은 정치, 경제, 사회제도나 문화적인 측면에서도 매우 다르다. 1800년대 후반의 스웨덴은 유럽 내에서 가장 늦게 산업혁명을 겪은 변두리 국가로서 경제적으로도 매우 낙후된 국가였다. 문화적으로도 영국이나, 프랑스, 독일 등의 유럽의 강국들과 비교하면 열세였고 국가적인 정체성도 채 확보되지 않은 상황이었다. 그러나 1900년대 초반의 스웨덴의 지식인들은 스웨덴 적인 것이 무엇인가 하는 문제로 고민하였고 이들의 그러한 노력은 1950년대에 와서 스칸디나비안 그레이스, 스웨디쉬 모던이라고 하는 스타일을 만들어 내게 하였다. 이러한 과정에서 스웨덴 국립 디자인 대학은 스웨덴 디자인 협회, 디자인 전문잡지 <스벤스크 포름>등과 함께 스웨덴 디자인 발전에 견인차 역할을 해왔다.

사물인터넷(Internet of Things)시대에는 다양한 사물이 연결되어 사물들 스스로가 데이터를 획득하여 이를 바탕으로 학습하고 동작한다. 이는 사물이 사람의 모습을 닮아가고 있다고 볼 수 있고 변화한 사물과 사람이 어떻게 소통하는가를 설계하는 것이 핵심 이슈로 떠오르고 있다. 이러한 IoT 환경이 도래함에 따라 UI 디자인 분야에서도 많은 연구가 진행되었다. 멀티모달리티(Multi-modality)와 인터유저빌리티(Interusability) 등의 키워드를 통해서 UI 분야에서도 복합적인 요소를 고려하려는 연구가 진행됐음을 알 수 있다. 하지만 기존의 UI 디자인 방법론으로는 IoT 환경에서 사용자 인터페이스(UI)를 설계할 때 사물, 사람, 데이터가 상호작용하는 방식에 대해서 구조화하고 테스트하는데 한계가 있다. 따라서 본 연구에서 새로운 UI 프로토타이핑 방법을 제안하였다. 본 논문의 주요 분석과 연구는 다음과 같다: (1) 먼저 사물의 행동 프로세스를 정의하였다. (2) 행동 프로세스를 토대로 기존의 IoT 제품을 분석하였다. (3) 사물성격(Personality of Things)유형을 구분 지을 수 있는 프레임워크를 제작하였다. (4) 프레임워크를 바탕으로 사물성격(Personality of Things) 유형을 도출하였다. (5) 3개의 대표 사물성격(Personality of Things)을 실제 스마트 홈 서비스에 적용하여 프로토타이핑 테스트를 해보았다. 본 연구는 새로운 UI 프로토타이핑 방법을 제안하여 더 총체적인 방식으로 IoT 서비스에 대한 사용자 경험(UX)을 확인할 수 있었다는 데 의의가 있다. 또한, 향후 본 연구를 발전시켜 인공지능(AI) 기술이 발전한 환경에서 지능화된 서비스의 정체성(Identity) 확립의 도구로 사물성격(Personality of Things) 개념을 활용할 수 있을 것이라 생각한다.

This study is on the internal and external characteristics along with the phenomena of dress and ornaments expressed in them by analyzing Re-orienting Fashion (which is a system of signs and symbols) based on the theories of semiology in the search for the Korean identity by examining a Re-orienting Fashion that is being reinterpreted. Re-orienting Fashion performs the role of signs that act in the spread of Oriental culture through the globalization of traditional dress and ornaments in the Orient. It also has a meaning that converts the world of fashion to a new direction. When analyzing the system of signs and symbols in Re-orienting Fashion (based on the theories of semiology) the conclusions are that an eclectic symbol system has been formed by the combination of the pursuit of modernization in traditional dress and ornaments with post-modernism. A nature-friendly symbol system has been shaped as a natural silhouette in terms of the combination with Eastern philosophy that searches for a harmony with nature according to ecological trends. The ideal of a symbol system means the introduction of design elements in traditional dress and ornaments of the East as a rejection of Western civilization and as an alternative to the fixed pattern of the West.

Masstige goods aimed consumers who want the fame and the emotional contents with reasonable price are presented overall and around the life style, from all the fashion items like bag and apparel to car, electric household, food, sports goods, furniture, toys, pets and performance of art, etc. Masstige casual, essentially different from the passed casuals which emphasized only price strategy, appeals to teenagers and young of twenties with a definite brand concept. Therefore masstige casual might be separated from business casual of a target aged thirties. Established celebrity brands have launched masstige brands matching the popularization of prestige goods. Armani Exchange from Armani, Marc by Marc Jacobs from Louis Vuitton are representative ones. DKNY from Donna Karen, MiuMiu from Prada, Paul smith Pink from Paul Smith can be added. These are relatively inexpensive, however the quality, design and shop's atmosphere are more exclusive than general brands. Consumers are over middle class and have a pride and fidelity to those brands. Leading Masstige trend, new luxury brands put the importance to the quality and aims middle class. To succeed in this field, companies should know exactly what consumers want, considering not only functional aspect but also emotional pleasure. Even though masstige has a weakness in pricing, it has to keep brand's proper benefit. Its price range could be wide to be in great demand but has to have elasticity and not to be expanded too much. Masstige industry should do its best not to damage original brand's identity. Forming family brand, like Armani made Georgic Armani, Emporio Armani and Armani exchange, system of parent brand and sub brands would be recommendable. From the launching time, masstige needs the effects to create a sensation and bring it into vogue and offer emotional value to the consumers.

The space is formed in close connection with a human life style, and whose significance is interpreted and recognized by characteristics given in the life culture to which they belong to. The spacial concept in terms of recognition plays an important role in the design of spaces. The understandings of its identity is an indispensable factor to forming the proper relation between the human beings and the space. This paper is the inquiry and the arrangement for geographical, thinking, and beauty-conscious features of Japan by the researches on documentary records in order to reveal the relationship between recognition and space as mentioned aboved. Also this paper presents the frame(system) which can draw the method of space construction and its expression and then seize and analyze the reality of space by re-arrangement for these various cultural background on the center of the relationship with Japanese spacial cognition. And this paper analyzed and arranged expressive features for Japanese spacial concepts by applying this analysis frame to contemporary commercial spaces in Japan. In results this research revealed that Japanese spacial features is always in the consciousness for cognitive space on the design of space , and in the features the neutral and several layered spaces are showed in complexed and mutual connected forms. These may be the methods for the relationship establishment between human and space on the ground of unique spacial concepts which is commonly found not only in traditional spaces but also in contemporary spaces in Japan.

The facade, an exterior material of a building, is one of the crucial factors that determine its morphological identity and its functional levels, such as energy performance, earthquake and fire resistance. However, regardless of the type of exterior materials, huge property and human casualties are continuing due to frequent exterior materials dropout accidents. The quality of the building envelope depends on the detailed design and is closely related to the back frames that support the exterior material. Detailed design means the creation of a shop drawing, which is the stage of developing the basic design to a level where construction is possible by specifying the exact necessary details. However, due to chronic problems in the construction industry, such as reducing working hours and the lack of design personnel, detailed design is not being appropriately implemented. Considering these characteristics, it is necessary to develop the detailed design process of exterior materials and works based on the domain-expert knowledge of the construction industry using artificial intelligence (AI). Therefore, this study aims to establish a detailed design automation algorithm for AI-based condition-responsive exterior wall panels and their back frames. The scope of the study is limited to "detailed design" performed based on the working drawings during the exterior work process and "stone panels" among exterior materials. First, working-level data on stone works is collected to analyze the existing detailed design process. After that, design parameters are derived by analyzing factors that affect the design of the building's exterior wall and back frames, such as structure, floor height, wind load, lift limit, and transportation elements. The relational expression between the derived parameters is derived, and it is algorithmized to implement a rule-based AI design. These algorithms can be applied to detailed designs based on 3D BIM to automatically calculate quantity and unit price. The next goal is to derive the iterative elements that occur in the process and implement a robotic process automation (RPA)-based system to link the entire "Detailed design-Quality calculation-Order process." This study is significant because it expands the design automation research, which has been rather limited to basic and implemented design, to the detailed design area at the beginning of the construction execution and increases the productivity by using AI. In addition, it can help fundamentally improve the working environment of the construction industry through the development of direct and applicable technologies to practice.
