This study analyzes the Western rocking chair style of the middle of the 20th century (1945~1970), and investigates academically characteristics from formative and practical points of view. The purpose of this study is to provide basic information on the design and production of the modern Korean rocking chair. In the 20th century, the production of the Western rocking chair displayed principles of both functionalism and optimism. These rocking chairs are constructed of various industrial materials including reinforced plastics, moulded plywood, aluminium, and steel as well as wood. Furthermore, a rocking chair suitable to the human body is made by industrial growth and innovative fabrication techniques such as designer's plastic from military in the First and Second World Wars. In those days, there are many different types of rocker style - traditional, plastics, structural, moulded plywood & bending, metal tubular, and wire mesh. More specifically, through economic prosperity and plastic development, the rocking chair is able to have light and bright colors, which shows sensible formality of the modern and structure.

The architectural design requires collaboration among various participants, such as architects, clients and engineers in the stages of the design process. Rapid development of information technology enables effective and prompt exchange and sharing of digital architectural information, otherwise should have been exchanged and managed by traditional ways. However, the core technology for supporting this demands has not been fully investigated so far. This paper aims to show the possibility of adopting network based architectural design information sharing system through surveying and analyzing the state-of-the-art network technology and its uses in architectural information exchange among various design actors. To realize these aims, this paper 1) investigates and analyzes the current status of network technology in the architectural and construction practice, 2) suggests systematic information exchange and sharing mechanism for architectural products and drawings data, and 3) demonstrates network based prototypical architectural information system.

Gait recognition, as a promising biometric, can be used in video-based surveillance and other security systems. However, due to the complexity of leg movement and the difference of external sampling conditions, gait recognition still faces many problems to be addressed. In this paper, an improved convolutional neural network (CNN) based on Gabor filter is therefore proposed to achieve gait recognition. Firstly, a gait feature extraction layer based on Gabor filter is inserted into the traditional CNNs, which is used to extract gait features from gait silhouette images. Then, in the process of gait classification, using the output of CNN as input, we utilize metric learning techniques to calculate distance between two gaits and achieve gait classification by k-nearest neighbors classifiers. Finally, several experiments are conducted on two open-accessed gait datasets and demonstrate that our method reaches state-of-the-art performances in terms of correct recognition rate on the OULP and CASIA-B datasets.

For the wear protection of cylinder bore in aluminum cast material the internal plasma spraying technology offers a new economical solution. The size and the weight of the engine blocks significantly can be decreased in comparison with the traditional cast iron sleeves. The coefficient of friction between piston ring and cylinder wall sensitively can be reduced and the wear resistance increased from several factors. The paper gives an overview of the technology from the AlSi cast alloys for engine block to the non destructive testing technology used after the machining by diamond honing. The actual results in engines of different types also will be shown. The economical advantages of the plasma spraying (or the internal coating in cylinder bore also will be discussed in comparison with the different alternatives of technology. The aspect of the market introduction also will be discussed in this paper.

Background: Ginsenosides are the main ingredients of ginseng, which, in traditional Eastern medicine, has been claimed to have therapeutic values for many diseases. In order to verify the effects of ginseng that have been empirically observed, we utilized the reverse docking method to screen for target proteins that are linked to specific diseases. Methods: We constructed a target protein database including 1,078 proteins associated with various kinds of diseases, based on the Potential Drug Target Database, with an added list of kinase proteins. We screened 26 kinds of ginsenosides of this target protein database using docking. Results: We found four potential target proteins for ginsenosides, based on docking scores. Implications of these "hit" targets are discussed. From this screening, we also found four targets linked to possible side effects and toxicities, based on docking scores. Conclusion: Our method and results can be helpful for finding new targets and developing new drugs from natural products.

With the widespread use of multifunctional devices, haptic sensation is a promising type of sensory channel because it can be applied as an additional channel for transferring information for traditional audiovisual user interfaces. Many researchers have shed new light on non-contact haptic displays for their potential use on ambient and natural user interfaces. This paper introduces several of the latest schemes for creating a mid-air haptic sensation based on their transfer medium: ultrasonic phased arrays, air nozzles, thermal and plasmonic lasers, and electromagnets. We describe the principles used in delivering haptic sensation in each technology, as well as state-of-the-art technologies from leading research groups, and brief forecasts for further research directions.

Berlage's importance in the history of the Modern Movements of Architecture lies in his effort to combine several sets of contradictory dual aspects of architectural values. Tradition and modernity are one of the contradictory dual aspects. For Berlage, tradtion and modernity were not tow opposing, but reconciliatory concepts. In this sense, Berlage thought that modernity did not mean a total rejection, but a reinterpretion of tradition. Berlage's concern with his contemporaty architectural situstion was how to revive the stagnant repetion of past styles in Historicism and, at same time, how to prevent an extreme rejection of tradition by the Avant-Gardists. Berlage's architectural belief that neither stagnant imitation of past styles nor extreme revolution can be an ideal model for his era, lies in a traditional art theory of 'style evolution' and the interpertation of Nature's lessons for it. This study is to understand Berlage's concept of 'style evolution' and the meaning of tradition and modernity in the early Modern Movements of Architecture.
