A vast amount of traffic data is produced every day from detection devices but this data includes a considerable amount of errors and missing values. Moreover, this information is periodically deleted before it could be used as important analysis information. Therefore, this paper discusses the implementation of an integrated traffic history database system that continuously stores the traffic data as a multidimensional model and increases the validity and completeness of the data via a flow of processing steps, and provides a what-if analysis function. The implemented system provides various techniques to correct errors and missing data patterns, and a what-if analysis function that enables the analysis of results under various conditions by allowing the flexible definition of various process related environment variables and combinations of the processing flows. Such what-if analysis functions dramatically increase the usability of traffic data but are not provided by other traffic data systems. Experimantal results for cleaning the traffic history data showed that it provides superior performance in terms of validity and completeness.

This study was undertaken to determine the effects of SNAGs (sustained natural apophyseal glides) and visual convergence biofeedback on the proprioception and neck disability of patients with chronic neck dysfunction. A total of 31 patients with neck dysfunction were assigned to either SNAGs (n = 16) or biofeedback (n = 15). The groups were assessed for proprioception and neck disability, before and after the intervention. The SNAGs were performed using belt with flexion, extension and right-left rotation, whereas biofeedback training included visual feedback training with deep neck flexor. Intervention was implemented for 20 minutes, twice a week for 4 weeks. Biofeedback training a showed significant effect on the joint position sense (left and right rotation) as compared to the SNAGs group (p< 0.05), whereas neck disability index was significantly effective for SNAGs (p< 0.05). Ed. Notes: The previous statement lacked clarity. I have suggested the edit as per my understanding. Please review and revise appropriately, if required. Therefore, the SNAGs technique is effective for neck function, and biofeedback training is a positive intervention method for enhancing the proprioceptive sensation. In future studies on patients with neck pain, it may be possible to select an intervention method based on the characteristics of the disease.

This paper introduces a new search model which can retrieve information instantly and easily about a given search word on Internet and control search spaces diversely. In the existing web searches, because the user has to stop his work, run web browsers, connect to special internet sites, and type the search word by keyboard. it is a long way and not a simple way. Also the search result is too much. The user suffers difficulties of multiple searches for different categories such as dictionary, image, video clips, etc. The software implemented in this paper enables for the user to select search word simply at any documents on the screen and make search started by simply pressing CRTL key and left button of the mouse simultaneously. The software is a mash up style using the Open API which is provided by a web site and can be freely available in any other sites. By calling different Open APIs of several web sites, the mash-up software can integrate search functions of many different sites. We evaluate that the software implemented in this paper will be a good reference of mash-up as one with characteristics of easy and instant search, simple result, diversity of search category, and scalability of search functions.

This study looks at plans for the efficient functions of the current terror response system in Korea. The results are derived from by comparing and analyzing American, British, German, Japanese, and Korean terror response systems. It focuses especially on addressing some problems with Korea's terror response system and how to operate it effectively. The study will systematically compare and analyze each nation's terror countermeasure studying organizational, functional, and legal aspects as standards. This study shows that there is not an exclusive terror response center in Korea compared with other nations such as America, the United Kingdom, Germany, and Japan. Also it is difficult to expect effective and vigorous operations due to weak cooperation across the relevant organizations. The presidential directive of the state's anti-terrorism action guidelines is legally ineffective. This means that on legal grounds, it is difficult to take actions to prevent the terrorism. Therefore, keys to counteracting terrorism derived from this study are summarized below. In the first place, an integrated terror response system should be set up for expansion of information sharing which leads to emergence effect. In the second place, the superior legislative systems should be made for the cleardefinition and extent of what the terror is, rigid enforcement of investigation, immigration, and keeping an eye on the funds raised by terrorists and tracking down the terrorists, the plan for eco-terrorism. In the third place, to augment security of vital facilities and peoples' awareness of terrorism safety should be emphasized and a cooperative system between civil and government organizations need to be built. In the fourth place, system for crisis management must be provided in an effort to maximize management system of terrorism and unify a decentralized emergency countermeasures effectively.

The capacity for tracing relationships among various artifacts which are created at each phase of software system development is essential for software quality management. Software release refers to delivering a set of newly created or changed artifacts to customers. The relationships among artifacts which comprise software release must be traced so that the work for customer's requirement of change and functional enhancement is effectively established. And release management can be effectively realized through the integration of configuration management and change management. This paper proposes the technique for supporting change management of artifacts and for tracing relationships of artifacts which comprise software release through the integrated environment of personal workspace and configuration management system. In the proposed environment, the visualized version graph and automated tagging function are used for tracing relationships of artifacts.

Although, a number of DBMS vendors are scrambling to extend their products to handle XML, there is a need for a lightweight, DBMS and platform-independent XML repository as well. In this paper, we describe such an XML integrated repository system, that solves the following functions : generating relational schema from XML DTDs for storage of XML documents, importing data from XML documents into relational tables, creating XML documents according to a XMLQL(XML Query Language) from data extracted from a database and synchronizing the replicated XML documents. In the XML repository systems, the efficient change detection techniques for XML documents is required to maintain the consistency of replicated XML data because the same data in the repository can be replicated between so many different XML documents. In this paper, we propose a message digest based change detection technique to maintain the consistency of replicated data between client XML documents and a XML data in XML repository systems.
