The wide-spread use of the broadband Internet service makes the cloud computing-based gaming service possible. A game program is executed on a cloud node and its live image is fed into a remote user's display device via video streaming. The user's input is immediately transmitted and applied to the game. The minimization of the time to process remote user's input and transmit the live image back to the user and thus satisfying the requirement of instant responsiveness for gaming makes it possible. However, the cost to build its servers can be very expensive to provide high quality 3D games because a general purpose graphics system that cloud nodes are likely to have for the service supports a single 3D application at a time. Thus, the server must have a technology of 'realtime multiple rendering' to execute multiple 3D games simultaneously. This paper proposes a new architecture of 2-tier servers of clouds nodes of which one group executes multiple games and the other produces game's live images. It also performs a few experimentations to prove the feasibility of the new architecture.

This study focuses on the right to self-determination, which has a higher possibility of infringement on rights, for people with developmental disabilities, who are more vulnerable to rights protection than other types of disabilities, and seeks to obtain implications of the basis for academic discussion and practical strategies. To this end, data were collected through a structured survey on 302 social workers in Seoul, Gyeonggi, and Gangwon area to identify the importance and execution degree of self-determination components of the developmental disabled, and descriptive analysis, differences. analysis, matrix analysis was applied. As a result of the analysis, the importance and performance degree were evaluated at an absolute level lower than the positive level, and the overall average standard execution degree was found to be applied relatively later, and the difference between the two levels was statistically significant. Meanwhile, goal setting and achievement, self-management and regulation, branch recognition and perception, etc. were identified as under-action elements as disparity between importance and performance. Therefore, in order to improve the balanced positivity of social workers and people with developmental disabilities in consideration of the reciprocity of human rights protection, applied behavior analysis, positive behavior support, and individualized service plan based on the application of a person-centered program and self-determination improvement program are applied. Suggestions were made on detailed strategies such as accounting.

Recently, the USN (Ubiquitous Sensor Network) technology is emerging as an aspect of digital convergence trends which is being rapidly evolving in the whole society. The technological feasibility for the various application services using the USN is researched in numerous industries, but, in the agricultural field, the market of USN application service, technology adoption and commercialization have been delayed. In the agricultural field, the ubiquitous technologies could lead to huge change in the conventional surroundings such as growth environment of livestock, crop cultivation and harvest. In this paper, to offer a integrated management, we construct a u-swinery(ubiquitous swinery) system which is consisted with USN environmental sensors to collect information from physical phenomenon such as luminance, relative humidity, temperature and ammonia gas. Numbers of CCTV were also installed to monitor inside and outside of the swinery. The u-swinery integrated management system can monitor and control the condition of swinery from remote sites. Furthermore, by gathering the cumulative environmental data from the system, the optimal growth condition for the livestock could be created.

Evaluating ubiquitous computing services is important for the commercialization of the ubiquitous services which will be running on electronic markets. However, despite its importance and usefulness, assessing ubiquitous computing services is still in its early stage. Moreover, sufficient study of making a distinction what are 'ubiquitous computing services' or not has not been provided yet. Hence, this paper aims to propose an integrated methodology to assess the ubiquitous computing services. A multilayered approach is considered to assess not only technical but also behavioral perspectives. To show the feasibility of the assessment model, three use cases are studied and evaluated.

This study investigates methodological implications of cyberspace and information technology for online survey research Online survey method provides useful methodological tools for collecting empirical data for the study of cyberspace, In terms of sampling frame , selection method, and questionnaire from four major types of the online survey research can be found: member survey visitor survey e-mail survey and the electronic survey. Online survey research with sample design(population specification error. sampling frame error, selection error) measurement (measurement instrument bias system-related processing error, nonrespone, and response bias) and research ethics (privacy and netiquette) pose important methodological issues for the survey. The realization of the technological possibilities of online survey will be possible only through a right consideration of these issues.

There are various kinds of applications if one can develop a remote execution system using for legacy 3D APIs. It can be used in implementing a cloud gaming service based on the real-time video streaming technology. Or, it can also be used in implementing a GPU virtualization for simultaneously rendering of many different 3D applications. The OpenGL API consists of independent global functions while the Direct3D API consists of Microsoft COM-based interfaces and their member functions, which makes the implementation of remote rendering system more difficult. The purpose of the paper is to show the applicability of the technology to any legacy 3D API by successfully designing and implementing a remote rendering system using the Direct3D API. It applies the implementation to a sample Direct3D application and also performs a few experimentations to show the technical feasibility.

Blockchain technology has the potential to revolutionize trust models and business processes in a variety of industries. However, it is considered to be the initial stage of the system that pursues autonomy rather than efficiency, and it is necessary to monitor and inspect the distributed ledger technology from the price and introduction time as compared with the existing relational DB transaction technology. However, domestic and foreign private sectors have already been activated by applying block-chain technology in the national domain, and the block chain is devoid of doubt that it is an exaggerated technology, characterized by the invariance of the record, transparency, and autonomous execution of business rules. It has begun to be utilized in history, identity, certification and auditing in the financial industry as well as various industries. In this paper, we analyze the problems such as security weakness, insufficient regulatory environment, technical consensus and lack of common standard. In addition, the business sense and possibility of the block chain technology is expected to be the innovation of the industrial ecosystem by entering into the reality system from the concept through monitoring the actual introduction performance in the field of copyright, logistics, health care and environment.

Web service Technology has been developing rapidly as it provides a flexible application-to-application interaction mechanism. Several ongoing research efforts focus on various aspects of Web service technology, including the modeling, specification, discovery, composition and verification of Web services. The approaches advocated are often conflicting-based as they are differing expectations on the current status of Web services as well as differing models of their future evolution. One way of deciding the relative relevance of the various research directions is to look at their applicability to the currently available Web services. To this end, we conducted a survey on currently publicly available Web service repositories. Our aim is to get an idea of the number, complexity and composability of these Web services and see if this analysis provides useful information about the near-term fruitful research directions.
