As Android platform and its applications are widely used, it is necessary to assure the reliability and safety of Android applications. The capture and replay technique is widely used for reproducing the crashes in Java applications. In this paper, we adapt the context-based capture and replay technique to Android applications by considering Android activity structure and its GUI characteristics. Our capture and replay technique uses probe code insertion based on AspectJ for minimizing the original code change and for enhancing the efficiency and reusability of the probe codes. For proving the efficiency of our technique, we provide a case study and execution overhead comparisons with related works, in which our approach has merits in GUI oriented Android applications with relatively low execution overhead.

There is few research about contact problem for a rigid surface with an arbitrary shape in SPH. The variational equation based on the virtual work principle is derived and its solution is obtained by the penalty method. It is proposed a new method that can determine the parameters for a penetration and a penetration rate used in the penalty method. The reproducing condition is adopted to correct the deficiency of kernel on the boundary. In order to calculate a penetration of particles, after checking boundary particles for deformable body boundary normal vectors were determined on the rigid surface. Numerical simulations for models which have rigid surface with an arbitrary shape were conducted to validate the proposed method in 2D. The results of those analysis represent that the contact algorithm proposed in this study works properly.

This paper presents the road simulator control technology for reproducing the road input signal to implement the real road data. The simulator consists of the hydraulic pump, servo valve, hydraulic actuator and its control equipment. The QFT is utilized to control the simulator effectively. The control system illustrates a tracking performance of the closed-loop controller with low order transfer function G(s) and pre-filter F(s) for a parametric uncertain model. A force controller is designed to communicate the control signal between simulator and digital controller. The efficacy of the QFT force controller is verified through the numerical simulation, in which combined dynamics and actuation of the hydraulic servo system are tested. The simulation results show that the proposed control technique works well under uncertain hydraulic plant system. The conventional software (Labview) is used to make up for the real controller in the real-time basis, and the experimental works show that the proposed algorithm works well for a single road simulator.

This paper presents the road simulator control technology for reproducing the road input signal to implement the real road data. The simulator consists of the hydraulic pump, servo valve, hydraulic actuator and its control equipment. The QFT(Quantitative Feedback Theory) is utilized to control the simulator effectively. The control system illustrates a tracking performance of the closed-loop controller with low order transfer function G(s) and pre-filter F(s) for a parametric uncertain model. A force controller is designed to communicate the control signal between simulator and digital controller. Tracking specification is satisfied with upper and lower bound tolerances on the steep response of the system to the reference signal. The efficacy of the QFT force controller is verified through the numerical simulation, in which combined dynamics and actuation of the hydraulic servo system are tested. The simulation results show that the proposed control technique works well under uncertain hydraulic plant system. The conventional software (Labview) is used to make up for the real controller in the real-time basis, and the experimental works show that the proposed algorithm works well for a single road simulator.

This study was conducted to examine how patchwork was expressed in fashion based on theoretical background on its brief history and expression styles and to show its possibility of creating ways for new expression in modern fashion. This study reviewed literatures on definition, history and styles of patchwork and investigated mainly works, which had been presented in collections home and abroad since 2000, to analyze its expressive characteristics shown in modern fashion. According to analysis on the expression of patchwork, it used various painting techniques such as patterns, colors and surface effect. It included patchwork having patterns provoking elusion of fairy tails; containing painting expression of reproducing works of artists; using colors boldly and contrasting strong primary colors directly to establish purity of painting and to pursuit characteristic expression; and using expression techniques of pure art such as gradation and cutting. Second, it used a compromise expression in materials, methods and substances. Patchwork which had used cloth without a pattern or printed fabric, utilized various materials like vinyl, paper, leather, metal and plastic and had a figurative value showing a solid expression as an objet itself with new techniques and changes of connecting methods. Thirdly, it used tradition patchwork techniques. Pieced patchwork, crazy patchwork and images of traditional odd ends of cloth covering a meal were applied to a whole area or a part of cloth to avoid monotony of design and to use it as a decoration.

The purpose of this study is to elucidate that photo, which has been used as original photo's purpose of information transfer in modern age, is now used as romantic reproduction which is the communication methods of architect's idea and thought through photographic vision which is beyond photograph own capabilities. The photos of Mies van der Rohe and Le Corbusier's architectural works are taken as an example for studying and analysing the way of deliverying the concept of creative work in the functional spaces in the modern era. It looked at the way of modern archirecture configuration, which architects wanted to show by pictures, such as concurrency, movement, sense of exhibition and concept of time-space and planarity on photographic vision such as multiview, movement, daily life exclusion, scenography and perspective loss. Reflecting that, I presents Le Corbusier and Mies van der Rohe's intention through photo by analyzing their picture of architecture by way of photograph techniques-camera position moving, over exposure, photomontage, silhouette technic and overlap technic. Mies van der Rohe and Le corbusier demonstrated the change and manipulation of the their architectural photos in different point of view. They express their architectural theories by photos of their works and overcome the limitation of expression of constructed building designed by them. The photos of architects's works in the case study with photos and descriptions introduce to their design concept. The design concept of the architects have become ideal concept for many contemporary architects and keep reproducing through the photos of their architectural works.

Unlike other body arts, body painting illuminates the value of art using eco-friendly formative activity and natural environment and highlights the need of eco-friendly activity. However, although body painting has focused on forming right relationship between human beings and nature, there are few researches which are linked with nature art. Therefore, the purpose of this study is to argue the need to study body painting as nature art in connection with natural environment and analyze body painting according to nature art types. The study methods included both theoretical review and empirical review. The theoretical review examined the concept and characteristics of nature art through previous researches and literature and the empirical review looked into the types and works of nature art and applied them to body painting works. The results were as follows. First, an installation type was possible by arranging and attaching certain materials to the body. Second, a physical type was possible by representing body itself as the part of nature. Third, a symbolic type was possible by making body appearance as a some symbol based on artist's idea. Fourth, a sound type was possible by stimulating auditory hallucination using the nature of objects and sensing a sound. Fifth, an ecological type was possible by conveying the message of living things in nature to the body. Sixth, an interior type was possible by inducing indoor installation of works. Seventh, a poetic type was possible by making one feel a poetic inspiration expressed in nature using the mystery of the sea and a simple sequential pattern of floral leaves. Eighth, a drawing type was possible by adding artist's intentional hand with a pictorical technique. Ninth, a indigenous type was possible by reproducing South American indian's primitive style. The review of this study suggests that body painting works have been expressed in experimental and temporary arrangement like nature art in nature and can be applied according to nine types of nature art.

3D printing technology, which is expected to play a leading role within the Fourth Industrial Revolution, is becoming distinguished not only in the space, automotive, medical and engineering industries, but also in the area of design. The fashion and textile structures created by 3D printing technology were classified into three types - basic structure, unified structure, and a new physical structure. When traditional weaving, knitting, and stitching was reinterpreted through 3D printing, there were apparent limitations in reproducing the characteristics of fabric structures due to differences in the materials and structures of traditional textiles. New physical structures are being developed to break away from merely reproducing traditional textile structures, and to bring out the characteristics of 3D printing technology. As examples of new physical structures, there are the kinematics structure which utilizes the hinge method, mesostructure cellular material, and the N12 disk structure. Such techniques potentially open a new paradigm of fashion and textile structures. Some innovative aspects of 3D printing technology may result in changes in the methods of collaboration, manufacturing, and distribution. Designers are receiving help from specialists of various backgrounds to merge 3D printing technology to create original works. Also, 3D printing not only makes personalized custom designs available, but shortens the distribution channels, foretelling a change within the fashion and textile industry.
