  • In this paper, we recall the definition of soft set, fuzzy soft set, hesitant fuzzy set and hesitant fuzzy soft set and some of their examples. We define the concept of hesitant fuzzy soft multiset which combines hesitant fuzzy soft set and soft multiset theory. We also define basic terms in hesitant fuzzy soft multiset with relevant examples. Some basic operations such as restricted intersection, extended intersection, union, restricted union, AND-product and OR-product and their properties are given, supported with illustrative examples. We finally establish some important results, including De Morgan's inclusions and laws.

  • Buckling of cylindrical structures has been extensively researched, because it is an important phenomenon to be considered in structural design. However, the evaluation of thermal effects on the buckling of cylindrical structures has been insufficient; therefore, this study evaluates this thermal effect using shell elements. In addition, the thermal effect on the buckling of temperature-dependent nonlinear materials was evaluated. Nonlinear and linear buckling analyses were performed using the arc-length method to investigate the behavioral characteristics of a cylindrical structure. The basic theory of the linear buckling analysis of a cylindrical structure subjected to thermal stress was derived and presented by applying the thermal stress basic theory.

  • The present study is concerned with the thermoelastic interactions in a two dimensional homogeneous, transversely isotropic thermoelastic solid with new modified couple stress theory without energy dissipation and with two temperatures in frequency domain. The time harmonic sources and Hankel transform technique have been employed to find the general solution to the field equations.Concentrated normal force, normal force over the circular region, thermal point source and thermal source over the circular region have been taken to illustrate the application of the approach. The components of displacements, stress, couple stress and conductive temperature distribution are obtained in the transformed domain. The resulting quantities are obtained in the physical domain by using numerical inversion technique. Numerically simulated results are depicted graphically to show the effect of angular frequency on the resulted quantities.

  • This article is an application of new modified couple stress thermoelasticity without energy dissipation in association with two-temperature theory. The upper and lower surfaces of the plate are subjected to an axisymmetric heat supply. The solution is found by using Laplace and Hankel transform techniques. The analytical expressions of displacement components, conductive temperature, stress components and couple stress are computed in transformed domain. Numerical inversion technique has been applied to obtain the results in the physical domain. Numerically simulated results are depicted graphically. The effect of two temperature is shown on the various components.

  • The purpose of this study was to explore the various perspectives to read micro-history of Korean housing after the period of Opening the Port for foreigners. This study were designed to adapt original theory for exploring the unique housing perspectives without using strict basic assumption which were already developed in the area of sociology, history, anthropology and philosophy. Research method applied was literature review. Each perspective might give useful insight to read the micro-history of Korean housing on the way of change after the Period of Opening the Port in Korea. Adapted perspectives to housing history were critical theory perspective, microsociological perspective, everyday life perspective(phenomenology tradition, symbolic interaction tradition, Marxist tradition), discourse perspective, exchange theory perspective, conflict theory perspective, and life course perspective. Conclusively, each perspective must be adapted multi-supportively to read the housing phenomena, because housing change derived from complex causes and factors. The fruit of this study was to ensure the adaptable viewpoint to housing were useful to read the micro-history of housing change.

  • Dempster-Shafer Evidence Theory is available for multi-sensor data fusion. Basic Probability Assignment is essential for multi-sensor data fusion using Dempster-Shafer Theory. In this paper, we proposed a novel method of BPA calculation with signal assessment. We took notice of the signal that reported from the sensor mote at the time slot. We assessed the variation rate of the reported signal from the terminal. The trend of variation implies significant component of the context. We calculated the variation rate of signal for reveal the relation of the variation and the context. We could reach context inference with BPA that calculated with the variation rate of signal.

  • The change in radically changing era requires various interpretation of interior space and application according to it Minimalism shows simple and pure geometric structure and has been influencing to every aspect encompassing space till present. The features of minimalism in space is geometric structure and composition of simple and repetitive line, restrained simple space, pure and structural simplicity. When minimalism construction is discussed, the vocabulary of simplicity has been followed incidentally and has been discussed as concept of simplicity in new viewpoint through historical flow. The purpose of this study is analyzing basic features of John Pawson's ways of working and trying to define the semantics of the new simplicity concept in modern interior space. The new simplicity in John Pawson shows interactive relationship of eastern and western through basic consideration of fundamental elements such as space, light and materials. The relational simple in intermediation of the new simplicity expressed by amalgamation of eastern and western further from disparate interpretation for simplicity expressed in eastern and western is to review back the basic meaning of simplicity in minimalism. And I hope this study can offer various directions for new interior space accepting theory of the new simplicity and I think that new constructional alternative is required as physical space which can be matched with era of social, environmental chaos caused by this theory of the new simplicity.

  • Aesthetic consciousness of the body determines the form of clothing, reflecting the time and culture as well as the individual and society. Using 'body' to analyze the clothing form, my study develops a framework by which to classify the representation and non-representation of the body in fashion. Theoretically, this study draws from Jean Baudrillard's Simulation theory which maintains that simulation develops the whole edifice of representation. My study substitutes the successive phases of the image to that of (non) representing body in fashion. The correspondences between them are; first, 'image is the reflection of a basic reality' for the representation of physicality, second, 'image masks and perverts a basic reality' for the manipulation of physicality, third, 'image masks the absence of a basic reality' for the absence of physicality, and fourth, 'image bears no relation to any reality whatever' for the absence of body in fashion. Aesthetic ideal of the body is visualized in the form of a dress. Fashion continues to explore forms and images that transcend the traditional representations of the clothed body. My study suggests a framework to analyze bodily representation in fashion, focusing on the relationship between the clothes and body.

  • Purpose: The purpose of this study was to construct and test a structural equation model of health behavior compliance among patients with percutaneous coronary intervention based on self-determination theory. Methods: A total of 227 participants who received follow-up care after percutaneous coronary intervention were recruited. A structured questionnaire was used to assess health providers' autonomous support, basic psychological needs, autonomous motivation, controlled motivation, type D personality, and health behavior compliance. Collected data were analyzed using SPSS 21.0 and AMOS 21.0 program. Results: The final hypothetical model showed a good fitness with data: GFI=.94, RMSEA=.07, CFI=.96, NFI=.92, TLI=.94. The results revealed that autonomous support of health care providers, basic psychological needs, and autonomous motivation, and D-type personality accounted for 51.8% of health behavior compliance. Conclusion: The findings of this study indicate that enhanced autonomous support of health care providers is essential to promote patients' basic psychological needs and autonomous motivation. This leads to maximized compliance to the health behaviors among patients who underwent percutaneous coronary intervention. We recommend that health care institutions establish various measures to foster the special environments in which health care providers can actively provide and utilize autonomous support for their patients.
