This mobile oriented Ad-hoc network yet steps on development level, related issues and standardization are progressing. This paper presented ad-hoc network's overview and overall property, followed by routing scheme that must be setup for communication between each nodes. Among several routing scheme proposed for standardization, ZRP that is foaled by this paper, is hybrid type algorithm, and only includes advantages of others This paper presented running process and implementation method, result that is made from network simulation, shows analysis of each parameter values's change. Each parameters changed with many differences according to Zone radius and communication node's location from simualtion that was performed changing a number of nodes and a velocity of nodes.

In general, the electronic commerce systems comprise the background system, terminal, network and smart cards. Among them, the smart card systems are expected to take a great portion of applications for the convenience of rapidly improving technology. The technology includes adopting RISC processors or co-processors for cryptography and developing new memory systems based on the standardization. In this paper, we investigate the overall trends of the technology and the standardization process of smart cards. We also propose the guidelines to enhance the capabilities of designing H/W and S/W related to COS(Chip Operating System).

Most software projects inevitably involve various types and degrees of uncertainty. Without proper risk assessment and coordination, software projects can easily run out of control and consume significant additional resource. Thus, risk management techniques are critical issues to information system researchers. Previous empirical studies of U.S. software firms support the adoption of development standardization and user requirement analysis techniques in risk-based software project management. Using data collected from software projects developed in Korea during 1999-2000, we conduct a comparative study to determine how risk management strategies impact software product and process performance in countries with dissimilar IT capabilities. In addition, we offer an alternative conceptualization of residual performance risk. We show that the use of residual performance risk as an intervening variable is inappropriate in IT developing countries like Korea where the role of late stage risk control remedies are critical. A revised model is proposed that generates more reliable empirical implications for Korean software projects.

The Internet provides a new way of doing business, but ease of copying and of sharing valuable digital information illegally across the Internet undermine many viable business models. This paper investigates the Digital Rights Management(DRM) as a means to provide safe protection and proper delivery of digital contents through the Information highway. First, we briefly summarize the current endeavor of DRM technical development and standardization process held in key technical working groups. Then, the paper provides a generic architecture for a DRM framework and shows the implementation of a prototype of DRM system incorporating key conceptual and technical standardization development. This study emphasizes the importance of developing the DRM architecture that provides the proper protection and safe transformation of digital contents in electronic commerce.

The purpose of this study was to develop a scheme to standardize apartment management expenses levy. I have conducted theoretical research on the literature for the foundation of this study. I have also surveyed many different kinds of levies with help from several apartment complex managers in Busan as well as the executive secretaries of Busan Citizen's Coalition for Economic Justice. I held 30 meetings with the experts in this process to discuss the standardization of the levy. The finalized scheme for standardization is in line with the Act for Management of Multiple Family Housing. Because description of the whole standardized scheme is too lengthy for one article, I decided to present it in three parts. This article is the first part of the series. The remaining two parts will be published in future issues.

Recently, Internet of Things (IoT) drives a large variety of research, development, and new type of markets. All type of devices and sensors will be part of the Internet of Things and will be able to communicate not only plain data, but also audio-visual, olfactory, and haptic media data. In addition, as the devices and sensors getting smarter, it is highly probable that they can process acquired media and metadata to extract higher level of information (e.g., semantics). To support such enhanced functionalities, ISO/IEC SC29 WG11 (MPEG) starts a new standard project, ISO/IEC 23093, called Internet of Media Things (IoMT) to provide standard data formats and APIs for media things. This paper presents the standardization activities of IoMT focusing on explaining terms, standard scopes, and major media things with their use cases. One of the use cases, an IoT system for a blind pedestrian navigation assistance, is evaluated to prove its effectiveness.

ISO 10303-112 is an integrated application resource of ISO 10303, commonly known as STEP, and specifies the procedural_sketch schema. The ISO 10303-112 provides general resources for the representation of modeling commands for the exchange of procedurally represented 2D CAD models. Procedural models have the advantage of being easy to edit, simply by changing values of parameters of their constructional operations. Such models are said to embody design intent, in the sense that modifications to them conform to the method of creation used by their original creator, and they also comply with any constraints implied by the particular constructional operations used. This paper introduces the development and standardization process of the ISO 10303-112, and describes the concept of procedural 2D CAD modeling, the way to represent the procedural 2D CAD models in STEP and the harmonization with other STEP resources.

The purpose of this study is to identify in two aspects the relationship between standardization activities and technological development at the firm level. The first aspect is to analyze the relationship between the current Korean industrial standards system and the firm's technological development vis-a-vis quality standards. The analysis reveals that even if Korean firms recognize the importance of standards, the level of product quality of the KS mark is still lower compared to the average world level. The survey also reveals that the reasons for acquiring ISO and KS marks are mainly aimed at enforcing company image and increasing quality management mind, rather than to foster technological innovation. The second aspect explores how much Korean industrial standards (KS marks) affect the firm's technological development in the Process of standards acquisition activities. The survey results show that standardization activities have a less positive impact on technological innovation than on the maintenance of consistent production works.

The purpose of this study was to develop an information system for home care service based on RAI(Resident Assessment Instrument). The standardization of service providing process was conducted using the steps of need assessment, triggers, application of CAPs, and care plan. The structure of MDsoft-HC was composed by MDS-CAPS system and system management system. A database on home care clients was accumulated by putting data, respectively, in general information, MDS-item, and MDS-result. Based on this data, the list of CAPs for the client was selected and monthly and annual statistics were calculated by problem result counts. It was suggested that standardization of a care plan would be integrated and short form of need assessment would be developed in the next stage.

So many countries, including England & Wales. USA, Australia, New zealand. Canada and Korea. now undergo deregulation process in the power system sector. Therefore. new terminologies in this field are generated more and more. It is the same case in our country. However the meanings and uses of these terminologies are so confused. This paper proposes standardization, refinement and explanation principles of new terminologies in electric power deregulation.
