Large access providers (ISPs) are seeking for new types of business agreements and pricing models to manage network costs and monetize better the provision of last-mile services. A typical paradigm of such new pricing norms is the proliferation of paid peering deals between ISPs and content providers (CPs), while on top of this, some ISPs are already experimenting with usage-based tariffs, usually through data-plans, instead of the typical fixed-based charging. In this work we define as common platform, the infrastructure in which a single ISP transacts with several CPs through peering agreements. In this context, we examine whether, and under which market conditions, the profitability of the involved stakeholders improves when the establishment of this platform is accompanied by a monetary compensation from the CPs to the ISP (paid peering), v.s. a scenario where their deal is a typical settlement-free one. In both cases, we assume that the ISP implements a usage-based access pricing scheme, implying that end-users will pay more for higher transaction rates with the CPs. Our framework captures some of the most important details of the current market, such as the various business models adopted by the CPs, the end-users' evaluation towards the ISP's and CPs' level of investments and the traffic rates per transaction for the offered services. By analysing the equilibrium derived by a leader-follower game, it turns out (among other practical takeaways) that whether or not the profitability of a CP improves, it highly depends on whether its business model is to sell content, or if it obtains its revenue from advertisements. Finally, we extract that consumer surplus is considerably higher under paid peering, which in turn implies improved levels of social welfare.

Our overall society circulates in line with the economical situations characterized by production and consumption and companies play the role of providing products and services, thus taking very significant responsibilities for the socioeconomical and cultural aspects in society. Therefore, when designers attempt to think of a way to enable companies and society to share their values and propose specific concepts and visualize outcomes, it is very critical to be able to understand economical philosophy and management strategies that interconnect companies with society and seek out proper design approaches. Recently, the world's enterprise and management culture tend to connect products and services provided by companies through chains of social values. Based on the abovementioned shift in the management paradigm, the researcher investigates and analyzes actual cases of attempts by Samsung Electronics to achieve its social impacts and studies actual roles and approaches of in-house designers with creativity and insights of humanity with regard to these attempts. Each case is selected from various fields such as the company's products and service development, business systems, culture, and external strategies and the ultimate goal is to learn about actual insights and approaches of designers to make contributions to the company's management with social impacts. Especially, humanity and creative thinking of many designers working in the manufacturing industry can have significant contributions to achieving its management with social impacts and effects of sustainable management.

This study provides a framework to assess network design under the regime of QoE (Quality of Experience). Our approach is expected to reveal the necessity of developing the QoE measures and applying this notion to network design, particularly in the mobile environment. Furthermore, our model shows the ample potential that both users and network providers are able to attain a win-win case by shifting the focus on network design and service operations from QoS (Quality of Service) to QoE. Since the former considers only relevant technological specifications, it may fail in capturing critical factors surrounding users, such as a context where the corresponding user is working on. For example, according to one study [13], the bit-rate, a widely employed QoS measure, shows inferior performance in provisioning network resources to the MOS (Mean Opinion Score), a representative QoE measure. Our framework develops the idea and construct a prototype to systematically assess network design and operations in terms of QoE. The proposed prototype aims at achieving a higher level of efficiency without severely deteriorating users' satisfaction level. We also provide some simulation results which support our idea. That is, reducing the chance of over-provisioning on the basis of the QoE paradigm results in a great flexibility. It may give price cut for users or postponement of network investment for providers or both. Our simulation results also seem robust irrespective of the forms of the QoS-QoE relationship.

3D printing has grown tremendously as the most noteworthy new technology in the manufacturing industries. In addition, the rapid development of computer science technology with 3D printing has created a new paradigm called Fractal Geometry, or a new form of digital art. This study explores the formative characteristics of 3D printing jewelry based on presentation of fractal geometry by classification of 3D printing jewelry's morphological types that except for producible shape with traditional mold manufacturing methods. The results of the study are as follows. The morphological characteristics of 3D printed jewelry are divided into their constitutive shapes by the repetition of the unit. The organic shape determined by superposition or overlapping, the systematic shape by distortion caused by distortion, and the variation in scaling by scaling. The formative characteristics, which are drawn from a study on the shape expression of 3D printed jewelry design using fractal geometry, consist of continuity, geometrical characteristics, and exaggeration. Continuity creates a new and self-assigned new space through a recursive structure through a cyclic structure that is formed along a single directional basis. The geometry of the geometry forms a three-dimensional and constructive structure comprised of the same size and structure of the same sized unit under the mathematical order of the geometry of Fractal's geometry. Exaggeration demonstrates the informal beauty and the maximization of the shape by expanding the scaling or superposition of a unit, by scaling the scale or he distortion of the units.

As the Korean construction market in the apartment housing has changed to a housing consumer focused market, interest and importance on efficient use and management on existing buildings has increased rather than demand for new buildings. Interest of housing consumers on apartment house quality has increased in this market paradigm, and this spontaneously is connected to quality flaw related defect disputes and lawsuits that the importance of defect diagnosis has continuously increased. This defect diagnosis is directly connected to maintenance charges in defect dispute and lawsuit processes that rather objective and highly credible progress of duty is required. However, most defect diagnosis firms today that progress defect diagnosis are using different diagnosis methods and depend on the experience of experienced professionals that there is no standardized defect diagnosis process. Therefore, the purpose of this study is to provide common defect diagnosis process model for defect diagnosis firms utilizing the BPMN (Business Process Modeling Notation) modeling method. It is expected that this will contribute to professional and reliable task performances of concerned defect diagnosis workers. Furthermore, it is expected that design lawsuit damage will be substantially reduced by standardizing defect diagnosis processes.

This study aims to identify the special features of high-concept funology observed in fashion products and expressional media by exploring funology in an era of high-concept, the emotional paradigm of the 21st century. High-concept funology in today's fashion can be explained as follows: First, 'virtual reality', which is often seen in fashion shows and fashion commercials, enhances consumer participation and involvement with blurred boundaries between the real world and the virtual world. With the expansion of various forms of real-time communication with consumers, positive images of the brand are being projected to the consumers. Second, 'form transformability', which is often found in fashion products, promotes customers' purchase desire as they are able to present themselves in a more versatile way in the fashion product that is changeable in various designs. Third, 'integration of different fields', which is easily found in various fashion goods, engages consumers in a mutual interaction under an entertaining setting with the product that is made to satisfy their needs attuned to their digital lifestyle. Fourth, 'interactive responsiveness', which is mainly recognized in fashion stores and commercials, is characterized by its interactive playfulness that encourages consumer participation through entertainment contents and promotes brand intimacy, eventually adding more value to its name.

Recently the computing environment has been moved to open architectures that include Web technologies. Web Service is one of import component of the new paradigm. This paper presents a design and implementation of GIS Web Service for mobile devices. As many mobile devices are equipped with GPS (Global Positioning System), it is required to handle the position information more effectively. We have extended the proxy program in the client device to actively send the context information to the server. Based on the context information the server determines the optimal service mode to a particular client. A working example of location?based GIS Web Service is also presented. By using Web Service standards and XML messages we can achieve the maximal interoperability for heterogeneous mobile devices.

Purpose: Islamic banking products and services have always claimed to be unique from its traditional interest-based counterpart. However, in practice, many Islamic banks are alleged to have drifted away from its paradigm version. The purpose of this study is to gauge the perception of university students in Malaysia towards Islamic banking products. Research design, data and methodology: Data were collected from 250 Malaysian university students. Structural Equation Modeling (SEM) was performed to test proposed hypotheses to identify factors influencing customers' perception toward Islamic banking products. Results: The main finding indicates that most of the respondents are familiar with Islamic banking products and consider Islamic banking products as useful as its conventional counterparts. The regression results show that respondents are less convinced of adherence to Shari'ah, efficiency and helpfulness of existing Islamic banks. Conclusions: This is a cue to the Islamic banks' stakeholders that they need to realign their practices in an ethically responsible way in accordance with Shari'ah if they wish to secure existing customers and attract potential ones. In a competitive banking environment, most banks provide efficient and readily available service; thus, focusing on this as a strategy hardly distinguishes an Islamic bank from an interest-based bank.
