Fashion pictorials are recognized as another form of communication method beyond the concept of simply providing information or being artistic photography. Therefore, it is believed that there is necessity to know methods of making a strong impression on people's conscience by effective usage of various presentation techniques that can be used in fashion pictorials. This research studied characteristics of closed form and open form of Wolfflin's precept of forms presented in scene construction. Depaysement technique was classified into three classes which are alien transportation of a part, deformation and ambivalence of an image through literature review of depaysement presentation technique. After studying the concept and characteristics of narrative applicable as the open form, Annie Leibovitz's "Alice's Adventures in Wonderland" published in an actual fashion magazine was analyzed as an empirical study based on the theoretical research. Through this study, potential of applying depaysement technique as a presentation technique of closed form and narrative as a presentation technique of open form on fashion pictorials was identified. Factors that infuse creativity and achieve uniformity in producing fashion pictorials were shown through analysis of actual fashion pictorials.

As mobile devices have developed, flash animations suitable for the existing web have solved part of the weakness caused by the image quality deterioration and the transmission capacity, but it is difficult to express 3D stereo-scopic images. Also, for the real time-randering of visual expressions for animation and the device technique for smartphone to accord with commercial demands, it is required to develop the 3D image processing technique. This paper studied on the image processing method for 3D animation capable of 3D graphic rendering with view system of android and OpenGL M3G in an embedded system device and OpenGL ES 2.0 library.

Mandibular implant overdenture is a good treatment option for complete edentulous patients with restoring removable prosthesis. Mandibular implant overdenture with two implants and locator attachments is widely used. It is tissue-supported overdenture that is made with the concept of conventional complete denture fabrication. There are two patients who provided impressions by open mouth technique and closed mouth technique in each case. In both cases, mandibular implant overdentures were restored with functionally and aesthetically satisfying results.

Purpose: To investigate the early results of limited open repair technique of Achilles tendon ruptures, and to describe the surgical technique. Materials and Methods: From October 2004 to February 2005, a total of 10 patients with Achilles tendon rupture underwent limited open repair. The average age of the patients was 39.3 years, and the average follow-up period was 9 months. The causes of injury were sports injuries in 8 cases, and slip down in 2. The mean interval between the injury and the operation was 9 days. The clinical results were assessed by patient's satisfaction, incision length, hospitalization, the ankle-hindfoot scale of American Foot and Ankle Society (AOFAS), and complications. Results: Of 10 patients, 8 were very satisfied, and the remaining 2 were satisfied. The mean incision length was 2.0 cm, and the mean hospitalization was 2 days. The mean AOFAS score was 97 points, and there was no complications such as infection, rerupture, or nerve injury. All patients returned to work at approximately 2 months, and resumed light exercise such as jogging at approximately 3 months. Conclusion: Limited open repair technique of Achilles tendon ruptures is provided for better cosmetic results, high patient's satisfaction, and functionally successful results without postoperative complications.

Latissimus dorsi tendon transfer is a well-established method for treatment of irreparable posterosuperior rotator cuff tears. We report on an anterolateral mini-open technique with a porcine dermal patch augmentation for latissimus dorsi tendon transfer. Use of this technique would result in avoidance of deltoid damage by anterolateral mini-open approach and reduction of failure rate by patch augmentation.

PURPOSE. This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cement-on crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL AND METHODS. Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test. RESULTS. The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P < .05). The closed tray and the resin-splinted open tray technique showed significantly different vertical gaps according to the angulation of implant (P < .05), but the A-F impression technique did not (P > .05). CONCLUSION. The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.

A depth map can be obtained by projecting/capturing patterns of stripes using a projector-camera system and analyzing the geometric relationship between the projected patterns and the captured patterns. This is usually called structured light technique. In this paper, we propose a new multi-threading scheme for accelerating a conventional structured light technique. On CPUs and GPUs, multi-threading can be implemented by using OpenMP and CUDA, respectively. However, the problem is that their performance changes according to the computational conditions of partial processes of a structured light technique. In other words, OpenMP (using multiple CPUs) outperformed CUDA (using multiple GPUs) in partial processes such as pattern decoding and depth estimation. In contrast, CUDA outperformed OpenMP in partial processes such as rectification and pattern segmentation. Therefore, we carefully analyze the computational conditions where each outperforms the other and do use the better one in the related conditions. As a result, the proposed method can estimate a depth map in a speed of over 25 fps on $1280{\times}800$ images.

This paper reports extensive experimental study done to compare workability and bond strength of five different types of polymer-based bonding agents for reinforcing bars in pinning retrofit. In pinning retrofit, steel pins of 6 to 10 mm diameters are inserted into holes drilled diagonally from mortar joints. This technique is superior to other techniques especially in retrofitting historic masonry constructions because it does not change the appearance of constructions. With an ordinary cement paste as bonding agent, it is very difficult to insert reinforcing bars at larger open times due to poor workability and very thin clearance available. Here, open time represents the time interval between the injection of bonding agent and the insertion of reinforcing bars. Use of polymer-cement paste (PCP), as bonding agent, is proposed in this study, with investigation on workability and bond strengths of various PCPs in brick masonry, at open times up to 10 minutes, which is unavoidable in practice. Corresponding nonlinear finite element models are developed to simulate the experimental observations. From the experimental and analytical study, the Styrene-Butadiene Rubber polymer-cement paste (SBR-PCP) with prior pretreatments of drilled holes showed strong bond with minimum strength variation at larger open times.

AVR parameter tuning for voltage control of power system generators has generally been done with the open-circuit model of the synchronous generator. When the generator is connected on-line and operating at rated load conditions, the AVR operates in an entirely different environment from the open-circuit conditions. This paper describes a new method for AVR parameter tuning using optimization technique with on-line linearized system model. As this method considers not only the on-line models but also the off-line open-circuit models, AVR parameters tuned by this method can give the sufficiently stable performance at the open-circuit commissioning phase and give the desired performance at the operating conditions. Also this method estimates the optimum parameters for desired performance indices that are chosen for satisfying requirements in some practical applications, the performance of the AVR can satisfy the various requirements.
