  • RTEMS is a real-time operating system using a GPLv2-based license, and is used in the aerospace industry, such as satellites. It is difficult to build a development environment for these special-purpose systems because of problems related to the hardware platform. This can be resolved by applying virtualization technology. However, increased execution time and performance degradation due to virtualization overhead can change timing behavior of real-time application, and needs to be minimized. In this paper, we aim to implement the network device driver of RTEMS for the standardized virtual network device called virtio in order to effectively utilize RTEMS in a virtualized environment. In addition, we describe the process of submitting implemented driver to the RTEMS community for contributing open source software and reflecting the various requirements of the community.

  • Objectives : Our study aims to provide a collaborative Internet terminology dictionary like Wikipedia, where about 30,000 concept terminologies with respect to traditional Korean medicine (TKM) are shared and TKM experts can edit the terminologies. Methods : The concept terminologies have been collected and refined for three years by the terminology management system, a custom-made software built upon the Oracle database, where each terminology is divided and normalized into one or more tables. The operation of Wikipedia depends on MediaWiki, a free and open source wiki software built upon the MySQL database. The database schema of our terminology management system is different from that of MediaWiki so that MediaWiki cannot used as our terminology dictionary. Thus, we propose a way to share and edit TKM terminologies with wiki-like user interface. Results : We devise a new terminology dictionary system to search and edit terminology upon the database of the terminology management system. The online terminology dictionary of TKM has the user interface and functions which is similar to Wikipedia to support collaborative works. Conclusions : Wikipedia is operated on MediaWiki which is can be downloaded and used freely under the GNU General Public License. However, there occur problems to use MediaWiki upon the legacy system. Thus, other wiki projects start, they should be considered.

  • Uniform Computer Information Transactions Act (UCITA) for e-commerce in non-UCC and non-UETA transactions, promulgated in 1999. The Act Drafted by the National Conference of Commissioners on Uniform State Laws. UCITA applies to contracts to license or buy software, contracts to create computer programs, contracts for on-line access to databases and contracts to distribute information over the Internet. UCITA does not apply to goods such as television sets, stereo equipment, airplanes or traditional books and publications. Goods generally remain subject to UCC Article 2 or Article 2A. Many transactions may include more than computer information. If that transaction covers non-goods subject matter, UCITA applies only to the part of the transaction which is computer information and other law applies to the other subject matter. In the event the other subject matter is goods, UCC Article 2 or 2A applies to the goods subject matter and UCITA applies to the computer information part. UCITA is coordinated with existing Articles 2 and 2A, so coverage of each to part of the transaction will be facilitated. With respect to other subject matter (primarily services) UCC Articles 2 and 2A have worked in mixed transactions with the common law applicable to the services.

  • Recently laser scanning technologies become widely used in many areas of the modern economy. In the following paper authors show a potential spectrum of use Terrestrial Laser Scanning (TLS) in diagnostics of reinforced concrete elements. Based on modes of failure analysis of reinforcement concrete beam authors describe downsides and advantages of adaptation of terrestrial laser scanning to this purpose, moreover reveal under which condition this technology might be used. Research studies were conducted by Faculty of Civil and Environmental Engineering at Gdansk University of Technology. An experiment involved bending of reinforced concrete beam, the process was registered by the terrestrial laser scanner. Reinforced concrete beam was deliberately overloaded and eventually failed by shear. Whole failure process was tracing and recording by scanner Leica ScanStation C10 and verified by synchronous photographic registration supported by digital photogrammetry methods. Obtained data were post-processed in Leica Cyclone (dedicated software) and MeshLab (program on GPL license). The main goal of this paper is to prove the effectiveness of TLS in diagnostics of reinforced concrete elements. Authors propose few methods and procedures to virtually reconstruct failure process, measure geometry and assess a condition of structure.

  • Purpose: This study aimed to identify the current status and correlations among scuba divers' knowledge of safety, compliance with safety rules, and ability to cope with emergency situations. Methods: There were 317 study subjects. Data were collected between September 21, 2012 and September 7, 2013, and analyzed using SPSS software version 21.0. Results: Of the participants, 89.3% wanted to be educated in emergency care, while 69.4% indicated that preparedness in emergency situations for divers is insufficient. 78.5% suggested a need to creat a legal standard for the prevention of accidents. The average scores among the participants showed 3.22 points for knowledge of safety, 3.09 points for compliance with safety rules, and 2.91 points for ability to cope with accidents and emergency situations, with strong correlation among them. The lower license level they had, the lower score they indicated. Conclusion: We suggest there is a need to strengthen systematic educations on knowledge of safety, compliance with safety rules, and the ability to cope with emergency situations and emergency care at the open water level. In addition, there is a need to creat legal standards to consolidate the effects of these changes.

  • The study of the compatibility of EPUB DRM, granted by the Korea Copyright Commission, as a CT R & D project (Project Title: Development of standard reference software technology for the International Standard EPUB-based eBook DRM) developed standards such as profile standards for encryption, digital signature and authentication certificates and standards for technical terms of rights information. In 2012, these four standards have been established as the Korean Industrial Standards under the names of 'Encryption specification for EPUB DRM', 'the Digital signature specification for EPUB DRM', 'the Certificate specification for EPUB DRM', and 'Definitions of Right Terms for EPUB DRM' through the ODPF(Open Digital Standardization Forum) and the TTA(Telecommunications Technology Association). In spite of the establishment of the eBook DRM standards, however, the absence of the standard technology which supports the compatibility for issues and changes of licenses makes it unable to use eBooks served by different eBook distributors. This study tries to investigate technological approaches to methods of license issues supporting eBook DRM compatibility on the basis of the above-mentioned four EPUB DRM standards and to provide an industrially accepted technological model.

  • In this paper, we propose an efficient car management system based on object-oriented modeling using car number recognition and smart phone. The proposed system perceives car number of repair vehicle after recognizing the licence plate using an IP camera in real time. And then, existing repair history information of the recognized car is be displayed in DID. In addition, maintenance process is shooting video while auto maintenance mechanic repairs car through IP-camera. That will be provide customer car identification and repairs history management function by sending key frames extracted from recorded video automatically. We provide user graphic interface based on web and mobile for your convenience. The module design of the proposed system apply software design modeling based on granular object-oriented considering reuse and extensibility after implementation. Car repairs center and maintenance companies can improve business efficiency, as well as the requested vehicle repair can increase customer confidence.

  • Structure and/or fluid analysis is gradually increased by an essential design process in the small and medium-sized businesses (SMBs) because of the needs for a rapid design process and the certification about the supplement of the parts by the large business (LB). In this paper, we developed the web-based ezSIM platform installed in the resources integrated system server. The ezSIM platform is based on the heterogeneous linux and windows operating system for the user-friendly connection with the part of the analysis for the SMBs. The procedure of the structure/fluid analysis service module using the public software and the license-free open code in the ezSIM platform was explained. The convenience of the ezSIM platform service was presented by the reaction rate of the graphic motion compared with that of a local PC and the solving and pre-post processing interface compared with that of the KISTI supercomputer. The web-based ezSIM platform service was identified as a useful and essential platform to the SMBs for the usage of the structure and/or fluid analysis procedure.

  • The Internet is a highly distributed and complex system consisting of billion devices and has become the field of various kinds of conflicts during the last two decades. As a matter of fact, various actors utilise the Internet for illicit purposes, such as for performing distributed denial of service attacks (DDoS) and for spreading various types of aggressive malware. Despite the fact that numerous services provide information regarding the threat level of the Internet, they are mostly based on information acquired by their sensors or on offline statistical sampling of various security applications (antivirus software, intrusion detection systems, etc.). This paper introduces proactive threat observatory system (PROTOS), an open-source early warning system that does not require a commercial license and is capable of estimating the threat level across the Internet. The proposed system utilises both a global and a local approach, and is thus able to determine whether a specific host is under an imminent threat, as well as to provide an estimation of the malicious activity across the Internet. Apart from these obvious advantages, PROTOS supports a large-scale installation and can be extended even further to improve the effectiveness by incorporating prediction and forecasting techniques.

  • Korean public organizations create electronic documents through electronic document management systems under the e-Government scheme. A majority of these public documents are saved in vendor-dependent file formats, mainly HWP. Vendor-dependent formats can be opened only with specific software, which requires purchase. As the license does not guarantee compatibility between past and future versions, interoperability problems occur in long-term preservation, which need to be solved. Any error from the elimination of styles or no matching elements in document definition during conversion from vendor-dependent formats to the XML-based standard exchange format leads to file open failure or the modification of original documents. This study introduces the Open Document Format (ODF) and investigates the effects of adopting ODF in the creation, exchange, management, and preservation of public records.
