In this paper, an asymptotic method is employed to formulate nano- or micro-beams based on strain gradient elasticity. Although a basic theory for the strain gradient elasticity has been well established in literature, a systematic approach is relatively rare because of its complexity and ambiguity of higher-order elasticity coefficients. In order to systematically identify the strain gradient effect, an asymptotic approach is adopted by introducing the small parameter which represents the beam geometric slenderness and/or the internal atomistic characteristic. The approach allows us to systematically split the two-dimensional strain gradient elasticity into the microscopic one-dimensional through-the-thickness analysis and the macroscopic one-dimensional beam analysis. The first-order beam problem turns out to be different from the classical elasticity in terms of the bending stiffness, which comes from the through-the-thickness strain gradient effect. This subsequently affects the second-order transverse shear stress in which the surface shear stress exists. It is demonstrated that a careful derivation of a first strain gradient elasticity embraces "Gurtin-Murdoch traction" as the surface effect of a one-dimensional Euler-Bernoulli-like beam model.

In wind load calculations based on pressure measurements, the concept of 'tributary area' is usually used. The literature has less guidance for a systematic computational methodology for calculating tributary areas, in general, and for scattered pressure taps, in particular. To the best of the author's knowledge, there is no generic mathematical equation that helps calculate the tributary areas for irregular pressure taps. Traditionally, the drawing of tributary boundaries for scattered and intensively distributed taps may not be feasible (a time and resource consuming task). To alleviate this problem, this paper presents a proposed numerical approach for tributary area calculations on rectangular surfaces. The approach makes use of the available coordinates of the pressure taps and the dimensions of the surface. The proposed technique is illustrated by two application examples: first, quasi-regularly distributed pressure taps, and second, taps that have scattered distribution on a rectangular surface. The accuracy and the efficacy of the approach are assessed, and a comparison with a traditional method is presented.

This paper aims to investigate the vibration analysis of functionally graded porous (FGP) beams using State-space approach with several classical and non-classical boundary conditions. The materials properties of the porous FG beams are considered to have even and uneven distributions profiles along the thickness direction. The equation of motion for FGP beams with various boundary conditions is obtained through Hamilton's principle. State-space approach is used to obtain the governing equation of porous FG beam. The comparison of the results of this study with those in the literature validates the present analysis. The effects of span-to-depth ratio (L/h), of distribution shape of porosity and others parameters on the dynamic behavior of the beams are described. The results show that the boundary conditions, the geometry of the beams and the distribution shape of porosity affect the fundamental frequencies of the beams.

Purpose - The postponement strategy, which delays the form, place, and production of products as late as possible, has been widely considered as a competitive supply chain management scheme in an era of mass customization and modular manufacturing. An interesting business phenomenon is that not all manufacturing/logistics firms choose the postponement strategy. Given that postponement is a counter-measure to speculation, which has some advantages under certain environments, the current imprudent inclination toward the postponement strategy may cause firms to lose the potential of the speculation strategy, an alternative strategy in supply chain management. Building on the logistics and manufacturing literature, this study examines characteristics of two contrasting strategies, postponement and speculation, and major factors favoring each strategy. Research design, data, and methodology - We apply the profiling approach to two business cases, HP printer and LG mobile phone. The profiling approach is a method of choosing a particular strategy aligned with environmental factors. While various approaches have been used to check the fit between a business strategy and environmental factors, the literature on manufacturing strategy and logistics has commonly adopted the profiling approach. Major factors used in profiling variables are derived from the literature. Two samples, HP printer and LG mobile phone, are selected, because they represent major characteristics appropriate for each strategy. The profiling is based on data from semi-organized interviews with managers. Results - The profiling approach shows that the postponement strategy is a suitable one for HP printers. Most factors, such as product life cycle, large production volume, low-price, product value, and monetary density, support delaying end products until as late as possible. Despite some exceptions, such as delivery time and economy of scale, our analysis states that the overall profile of HP printer is favorable for the postponement strategy. On the other hand, LG mobile phone may adapt the speculation strategy. Although it has large production volume and low delivery frequency, most characteristics support the speculation strategy for this product. An interesting finding is that, despite common perception that advanced technology products such as mobile telephones favor the postponement strategy, profiling proposes the speculation strategy for this product. Conclusions - Our analysis shows that speculation is not the universal option for supply chain management, and that, when choosing a specific strategy, one should consider many factors simultaneously. A major implication of our work is to emphasize the role of environmental factors such as supply chain variables in choosing an inventory strategy, and the importance of fit rather than solely strategic orientation. A theoretical contribution is to demonstrate the benefit of the simultaneous consideration of business variables in choosing specific strategies. For practitioners, our work leads us to consider the existence and the potential of speculation as a counter-measure to postponement. In addition, the comprehensive framework in this research may be instantly used in examining a practical strategy.

Purpose: To compare the clinical outcomes between the open posterior approach and arthroscopic suture fixation for displaced posterior cruciate ligament (PCL) avulsion fractures. Methods: A literature search was performed on MEDLINE, EMBASE, and the Cochrane Library databases. The inclusion criteria were as follows: papers written in English on displaced PCL avulsion fractures, clinical trial(s) with clear description of surgical technique, adult subjects, a follow-up longer than 12 months and modified Coleman methodology score (CMS) more than 60 points. Results: Twelve studies were included with a mean CMS value of 72.4 (standard deviation, 7.6). Overall, 134 patients underwent the open posterior approach with a minimum 12-month follow-up, and 174 patients underwent arthroscopic suture fixation. At final follow-up, the range of Lysholm score was 85-100 for the open approach and 80-100 for the arthroscopic approach. Patients who were rated as normal or nearly normal in the International Knee Documentation Committee subjective knee assessment were 92%-100% for the open approach and 90%-100% for the arthroscopic approach. The range of side-to-side difference was 0-5 mm for both approaches. Conclusions: Both arthroscopic and open methods for the treatment of PCL tibial-side avulsion injuries resulted in comparably good clinical outcomes, radiological healing, and stable knees.

The studies of correspondence between novel and nation-state, among which The Rise of the Novel by Ian Watt is supposed to be the first book, have flourished for more than twenty years, encouraged by Benedict Anderson's and Cathy Davidson's works. According to them, the novel should come simultaneously with, or after the foundation of the nation-state, and testify to its production or the emergence of its subject/citizen. This paper questions about these prepositions, trying to introduce a new paradigmatical approach, "between global and transnational historical approach," to first novels in transatlantic areas including England and atlantic coastal areas. In its complex relation to a variety of colonial, post-colonial, and transnational geopolitics, various cultural practices such as history, traveler's tales and epistolary novels can be included in the genre of the novel. The idea of the sexual contract by Carole Pateman is very useful because it helps more clearly understand the nature of relation between men and women in the capitalist reproduction, while the social contract tells about the relation between men as citizens. Unlike Freud in Totem and Taboo, Zilboorg argues that there were primordial and violent scenes such as rape before the first sexual contract. This paper will illuminate that "the rise of the novel" corresponded with the emergence of the sexual contract. In the so-called first novel Pamela, the heroine Pamela was threatened to be violated by Mr. B., and was really even confined in his cottage. Mary Rowlandson's The Captive Narrative shows that her body was confined as an English female captive, and troubled with imaginary rape by Indians which resulted in the unequal sexual contract between her and her puritan community in America. However, Leonora Sansay's Secret History in an alternative communality, which was not a nation-state, was different from both novels mentioned above, in that it shows the possibility of emancipation from their unequal marriage, the sexual contract. Therefore, it can be argued that "between global and transnational historical approach" has a possibility to provide a new vision of global sisterhood and solidarity to recognize globalized women's violence, and free themselves from the unequal sexual contract.

This study considered movie costumes shown in 'Alice In Wonderland' by Tim Burton based on the Theory of Fantasy in Literature by Tzvetan Todorov and Rosemary Jackson. The research method used was a case study on expression types of fantasy used in movie costumes with a literature research based on the Theory of Fantasy in Literature. The Theory of Fantasy in Literature has significance in suggesting a new theoretical approach for understanding a visual perspective and aesthetic characteristics shown in fashion as well as movie costumes. The conclusions of the study are as follows. First, fantasy can connote characteristics of the marvelous, the uncanny, and the imitative through a consideration of Theory of Fantasy in Literature. Second, the marvelous is what is not beautiful, not ugly, but is strange and surprising, and what escapes from the existing norm. The characteristics of the marvelous in movie costumes are expressed through cross-dressing or displayed by allowing the personified animal to wear clothes. Third, the uncanny is something that causes grotesque, disgusting, comic and recreational responses. The characteristics of the uncanny in movie costumes are expressed through exaggerating and artificially transforming the body. Fourth, the imitative is the property of trying to imitate or follow other things. The characteristics of the imitative in movie costumes are indicated by dismantling and expanding a form through borrowing costumes from various ages.
