This paper provides an overview of the E-learning service education on the last decade, In the early 2000's the emphasis of educational technology was on interactive multimedia- stand alone packages on computer hard disks or portable memory, which integrated a range of media forms in the lately. Customers handle finding the best sources of content.The system then uses social signals such as those coming from Facebook, Twitter, LinkedIn, delicious as well as clicks and views. The SNS and network infrastructure is sufficiently mature that the focus should shift to how to use the technology most appropriately to facilitate learning. As we study environmental conditions of the traditional internet and the mobile internet users in some ways. In this paper, analyze the nature of learning, role of educational and suggest alternative policy, innovation of e-learning service and effective e-learning environment in developing technology.

Spam refers to any unwanted or unauthorized commercial messages. Spam may violate individuals' privacy or other personal rights. Spam often overloads network traffic, wastes individuals' time, lowers productivity and quality of life, and limits the trustworthiness of Internet businesses. As the use of mobile messaging services and social networking services both on mobile communication networks and on the Internet increase, newer and more complex types of IT applications and services are often used as new means of spam. In this research, the characteristics and impact of new and future forms of spam, and anti-spam related policies and regulations are surveyed. To improve the effectiveness of anti-spam policies and regulations in Korea, adding a definition of spam in the law, changing policies to focus on the 'type of services' rather on the medium of transmission, and redefining the scope of 'commercial purposes' in Korean law are suggested.

Two of the main elements of Persian tangible heritage are rugs and gardens, which have evolved together from the dawn of Iranian history. Emerging from the same system of thought and geographical location, together they represent the Persians' world views, desires, dreams, and design paradigms. In this study, the Persian Garden's patterns, elements, typology, and meanings are introduced and compared with the same aspects of Persian rugs. This paper uses a qualitative comparative methodology to analyze rugs' designs and patterns in relation to Persian Gardens' design principles. Data is collected primarily through library study and observation. The author uses two categories for comparison: meanings and forms. First, the author identifies underlying meanings common to the two art forms and then introduces form, function, and general principal patterns into the analysis. There is a type of rug pattern, known as Chahar-Bagh (literally, "four gardens"), that mirrors a garden design, down to the details, which is the focus of this paper. Additionally, other representations of Persian Gardens in rug design, such as Shekargah ("hunting pattern"), are discussed, as are other rug patterns with fewer elements borrowed from garden design. The paper also considers several motifs that represent flora common in gardening on the Iranian plateau, some of which have symbolic meanings dating to the Zoroastrian era. By comparing these two mediums of art (garden and rug) in the context of Persian history and geography, it becomes clear that the Persian rug design, in its roots, is an attempt to bring a garden into interior space. The study shows that the forms, patterns, and meanings reflected in Persian rugs render the study of their designs incomplete without considering the history of gardens.

Non-representation creates difference and change that can be used as a creative design method that satisfies contradictory requirements for similarity and differentiation. This study drew upon the characteristics of the concept of non-representation expressed in contemporary art and architecture, in which Gilles Deleuze's philosophical thinking was reflected, and analyzed the non-representation depicted in contemporary fashion. The non-representation expressed in contemporary art and architecture is as follows. Non-representation of delaying becoming focuses on reverting to preexisting objects and redefining traditional meaning, thereby delaying the representation of latent meaning. Non-representation of non-becoming removes existing values and typical forms and expresses amorphousness. Non-representation of becoming by repetition or reiteration realizes the difference caused by the passage of time by repeating or overlapping shapes. Non-representation of becoming expresses the transformation of space by flowing through time rather than by actual movement. Non-representation in contemporary fashion shows the following expression characteristics. First, the non-representation of deferring becoming deconstructs the traditional values and forms of clothing and expresses designs by displacement or juxtaposition. Second, the non-representation of non-becoming is expressed concepts unrelated to the body and focus upon amorphous objects that do not become concretized forms. Third, generative non-representation by repetition and overlap expresses the possibility of change by overlapping clothing items or details expressed by repeating segmented objects. Fourth, generative non-representation by movement reproduces the meaning of space and time by moving the shape of the clothing or visually changing the surface of the material of clothing. As a result of the study, the non-representation shown in contemporary fashion aims for versatility to conform to social changes. This study provides new insight into the fashion design method by increasing the understanding of the cocnept of non-representation and showing its potential.

This study examines the significance of digital fabrication of scaled physical models in the digital design process and highlights the integration of design computing and digital fabrication in architectural education. Advances in CAD/CAM technologies have increasingly influenced building design and construction practices by allowing the production of complex forms that were once difficult to design and construct using traditional technologies. At the advent of digital architecture, schools of architecture introduced digital technologies to their curriculum, focusing more on design computing than digital fabrication, preventing students from completely mastering digital technologies. The significance of digital fabrication for scaled physical models as a design media within the digital design loop is discussed. Two case studies of leading schools of architecture that are successful in building the bridge between both areas are given. These focus on the curricular structure to integrate both areas within design studios. Finally, a curricular structure offering students a balanced approach to these areas of knowledge is proposed based on what was learned from these case studies.

In an ultrasonic motor, a piezoelectric ceramic material forms the active element which vibrates the stator, thus initiating the rotational motion. In the operation of ultrasonic motors, many factors exist that can affect the resonance characteristics of the piezoelectric ceramic component. For examples, these factors are the bonding conditions with the piezoelectric element, the magnitude of the input voltage, the normal force in the frictional drive and the emission of heat due to vibration and friction etc. Therefore, it is important to research properly the inclination for variation of piezoelectric ceramics in the circumstance where complex elements are involved. In this paper, we focus on the analysis of the resonance characteristics of an ultrasonic motor as a function of the magnitude of the input voltage and the normal force.

This study aimed to identify today's religious fashion motifs as elements for design development by examining the expression modes such as religious motifs in contemporary fashion. Methodologically, the study conducted literature review and empirical analysis of pictures and articles in domestic and foreign fashion collection magazines and other related data available on the internet and analyzed the collections of 1990 through 2009 with a focus on Christianity, Buddhism and Islam. As a result, this study identified two expression modes of religious motifs in the contemporary fashion. The first expression mode was to employ the forms of religious costumes and their associated images. The second one was to take on religious symbols and their associated images.

The purpose of this study is to find the characteristics of design council criteria of metropolitan cities in Koreas. For comparative analysis, four main concepts are used ; 1) self-administering vs discretionary 2) prescriptive vs performance 3) conformity vs contrast 4) point system of criteria. The results of this study were as follows; 1) there were three types of cirteria; strong discretionary (DG), discretionary oriented (BS, US) and combination type (SL, DJ, ICN, GJ) 2) structural properties of forms are controlled by prescriptive criteria, and layout or design elements by performance criteria 3) visual openness and diversity are main items of most metropolitan cities 4) street-faced design was neglected but tended to focus on the self-contained layout 5) visual density indexes were diversified from elevation blockage degree. For further advanced research, it is necessary to investigate the actual effects and differences of regulative types - prescriptive vs performance, and of each design criteria, especially prescriptive ones in improving the design quality.

The softening hyperelastic model based on the strain energy limitation is of clear concepts and simple forms to describe the failure of materials. In this study, a linear and a nonlinear softening hyperelastic model are proposed to characterize the deformation and the failure in granular materials by introducing a softening function into the shear part of the strain energy. A method to determine material parameters introduced in the models is suggested. Based on the proposed models the numerical examples focus on bearing capacity and strain localization of granular materials. Compared with Volokh softening hyperelasticity and classical Mohr-Coulomb plasticity, our proposed models are able to capture the typical characters of granular materials such as the strain softening and the critical state. In addition, the issue of mesh dependency of the proposed models is investigated.
