  • Based on the fact that high similarities exist between viewpoints of multi-view images, MV-HEVC achieves high encoding efficiency by performing conventional temporal direction prediction in a single viewpoint as well as inter-view prediction between viewpoints. In this paper, we propose to integrate SHVC and MVC (Multi-view Video Coding) to implement scalable multi-view video encoder using HEVC as a base layer. According to experimental results, it is verified that the BD-PSNR improvement reaches up to 1.5dB while reducing the BD-Bitrate by around 50~60%.

  • Firms or internal exchanges exist to eliminate or at least reduce transaction costs from the separating process in many firms by dealing more efficiently with bounded rationality, complexity, and tendency towards opportunism faced by the markets so that vertical integration is supposed to have a positive relationship with performance. The organizational structure of Korean economy in the latter part of the $20^{th}$ century is much related with this transaction costs' view. I propose to estimate the effect of vertical integration on the firm's performance using the data of the Korean listed corporations from 1991 to 1995, therefore. The estimated results show that vertical integration at firm level is negatively and significantly related with the firm's performance: the higher level of vertical integration the worse performance. However, the group level integration is not related with performance at all.

  • The view can provide the user an appropriate portion of the database through data integration and filtering. Views can be materialized for query performance improvement, and in that cse, their consistency needs to be maintained against the updates of the underlying data. They can be either recomputed or incrementally refreshed by reflecting the relevant updates. Since XML could represent the structural information of the documents, for the XML materialized views, new techniques that differ from the previous ones for incrementally refreshing the relational views are required. In this paper, we propose a framework of XML materialized view management where the XML view derived from the underlying XML documents are materialized and incrementally refreshed against the updates of the underlying documents.

  • Within residential high-rise market there are many value determining factors. Site condition, view, program, units and structure are important parameters that are directly related to the financial aspect of the project. However, most of the studies of high-rise building design focus on the facade and the shape strategies from an esthetic point of view without considering these factors. The objective of this study is to investigate new design approach that incorporates site, program and structural information at an early stage as a generator of building form and explore a wide range of strategies to negotiate these factors in the process of design/decision making. Not being based on designer's subjective preference or style, architects still can create interesting building design through integration and negotiation of various building information. Since this form is based on real data, not just play of form, we can expect that this form has great potential to be developed into real one at the later design phase.

  • When we make a place for people, interior space and exterior space are always connected, each influencing the other. To create a better space or increase the quality of an existing space, it is essential to look at the relationship of inside and outside and their boundaries. Without consideration of the landscape, the building itself gives only limited satisfaction to people. This is an important issue for anyone who deals with space. This study intends to explain the important need for a change in attitude towards our built environment and its intrinsic relationship with its natural context. In the study, I try to find design concepts for integration of inside and outside which have accumulated since early Modernism designers and consider cases with different solutions and approaches that make total design sense when looking at the inside and outside as a whole, then, through observation of the cases, I find 5 design methods(Opening, Continuing, Insulting, Wrapping, Interpreting) in connecting the two spaces and analyze the solutions. The various examples which are shown in each patterns will help us to find ideas for the best solutions of integration of inside and outside. It is true that the idea of integration of inside and outside will increase the quality of our environment and it comes with the current thoughts of ecological and sustainable design. Thereby, I suggest designers to change their manner to continuous and integrated point of view in dealing with built environment.

  • This paper describes a novel MEMS integration technique on a CMOS chip. MEMS integration on CMOS circuit has many advantages in view of manufacturing cost and reliability. The surface topography of a CMOS chip from a commercial foundry has 0.9 ${\mu}{\textrm}{m}$ bumps due to the conformal coating on aluminum interconnect patterns, which are used for addressing each MEMS element individually. Therefore, it is necessary to achieve a flat mirror-like CMOS chip fer the microelectromechanical system (MEMS) such as micro mirror array. Such CMOS chip needs an additional thickness of the dielectric passivation layer to ease the subsequent planarization process. To overcome a temperature limit from the aluminum thermal degradation, this study uses RF sputtering of silicon nitride at low temperature and then polishes the CMOS chip together with the surrounding dummy pieces to define a polishing plane. Planarization reduces 0.9 ${\mu}{\textrm}{m}$ of the bumps to less than 25 nm.

  • Purpose: This study aims to enrich the literature related on Patronage intention in the context of omnichannel in Tunisia. It reveals the determinants of Patronage intention in the fashion retailer context by examining the roles of omnichannel integration quality (IQ), omnichannel perceived value (PV), flexibility, operational logistics service quality (OLSQ) and customer satisfaction. Research design and methodology: A quantitative online survey with 400 customers of fashion retailers was executed. A structural equation modeling approach was applied to test the research hypotheses using AMOS 25 and SPSS 25 software. Results: The findings show that the omnichannel integration quality, omnichannel perceived value, and operational logistics service quality affect play crucial roles in customer satisfaction. A positive relationship between flexibility and operational logistics service quality was also highlighted. And it is also found that a higher omnichannel integration quality led to a higher omnichannel perceived value in the omnichannel retailing context. Furthermore, customer satisfaction within omnichannel retailing can enhance patronage intention. Conclusions: This research adds to the body of knowledge in omnichannel retailing and presents a comprehension of the omnichannel system from the customer's point of view. In addition, this study provides practical implications for omnichannel retailers to improve customer satisfaction and patronage intention.

  • Parallelism and performance enhancement of calculating view factors in KSDS developed by KARI is introduced in this paper. View factor is an essential parameters of radiation thermal analysis for a spacecraft, and the amount of computation of them is not negligible. Especially, independent integration of view factors at each position of the orbit because the relative displace between solar panel and main body of a satellite varies with the position on the orbit. This paper introduces a range of parallelism of computing view factor and their performance, detection of obstructions by spatial search algorithm based on KD-Tree, and the reduction of the calculation of view factors of a satellite with relative motion between solar panel and main body, called updating fractional view factor matrix, for satellite thermal analysis.

  • A mediator-wrapper system, which is one of integration methods of heterogeneous databases, preserves a virtual integrated view rather than physical movement of the contents of each database. In order for a mediator to preserve a virtual integrated view, it requires the schema manager of the wrapper which communicates with local databases. This paper presents a schema manager of a wrapper that provides a mediator with XML schema which is generated from relational database schema. The XML schema manager supports a user-defined XML view. We present the view tree model which is used for materializing the use-defined XML view to generate XML schema, and the conversion algorithm based on the proposed view tree model. This model is can be uniformly applied to all schema managers of heterogeneous information sources.
