Web designers generally use a story board, a site map, a flow chart or the combination of these for representing web sites. But these methods are difficult to represent the entire architecture of a web site, and may be not adaptive for describing the detail flow of web pages. To solve these problems to some degree, there were works using EMFG(Extended Mark Flow Graph) recently. However the conventional EMFG representation method is not adaptive to represent the dynamic interface of web sites because that cover only the static parts of a web site. Internet utilization is rapidly growing in our life and we cannot imagine the worlds of work, study and business without internet. And web sites recently have not only more complex and various architecture but also web pages containing the dynamic interface. Therefore we propose the representation method of these web sites - for example, a web site containing varying pages with time and varying page status or contents with mouse operations - using EMFG. We expect our work to be help the design and maintenance of web sites.

The popularity of the web based education has come the need for variety learning methods and for business to exploit the web not only for interoperability but also standardization. This way of standardization has come to researched for environments, contents and practical uses in ISO. The IEEE has special]y established five technical classes for LTSA which provide advanced e-learning environments. Feedback functions would not be supported and specified in standardization for Query Answer on LTSA. In this paper, we describe the query and answer model which we have developed on layer three of LTSA. We develop the redefined model for transforming data flow oriented into object or component based model. We have developed the Query Answer Metadata (QAM) based on Learning Object Metadata (LOM). We design and showed thing a prototyping implementation the Query Answer Learning Tool (QALT). We have used the QALT to address the problem of efficiency of web based education. We also used it to develop the related tools with quality and productivity.

Electronic commerce creates serious problems for tax administration because of difficulties associated with the identification of traders, coding of trade activities and so on. The core issue with respect to resolving tax-related problems in electronic commerce is first, the identification of individual transactions through internet and their contents as well as traders. Secondly, it is the ability of tax authorities to secure effectively such data and information as identifying taxpayers, taxable amount and tax evasion on time. The tax authorities are studying the way to resolve tax evasion associated with electronic commerce by using payment system. Above of all, it is imperative to establish a systematic international cooperation in collecting value added taxes for electronic commerce. In order to enhance the effectiveness of tax system, the authorities of different nations should make joint efforts to collect taxes by exchanging such information as identification and registration of business as well as details of transactions among nations of production and consumption.

In terms of creating widespread popularity and a high value added business, TV drama is recognized as an unrivaled entertainment content above any other TV program genres Although recently some broadcasting companies have been trying to set up a drama production system, it seems that a well-structured system has not been established, yet. This study analyses the practices and mechanisms of drama producing processes based on the in-depth interviews with the experts in the drama production fields in three major broadcasting companies. It is found that the Korean drama production system is 'a producer-director system' and that the strategies for the windowing effects are not systematically applied from the pre-production stage. For the broadcasting companies to strengthen the competitiveness through drama, the expert-producer system should be introduced, the production elements should be systematically managed, and the multi-use strategies should be effectively established.

This article describes a systematic roadmap master plan for advanced industrial safety and health policy in Korea, with an emphasis on. Since Korean industries had first emergence of industrial safety and health policy in 1953, enormous efforts have been made on upgrading the relevant laws in order to reflect real situation of industrial work environment in accordance with rapid changes of Korean and global business over three decades. Nevertheless, current policy has major defects; too much techniques-based articles, diverged contents in less organization, combined enforcement and punishments and finally enforcing regulations full of commands and control. These deficiencies have make it difficult to accommodate changes of social, industrial and employment environment in customized fashion. The approach to the solution must be generic at the level of paradigm-shift rather than local modifications and enhancement. The basic idea is to establish a new system integrated with a risk assessment scheme, which encourages employers to apply to their work environment under comprehensive responsibility. The risk assessment scheme is designed to enable to inspect employers' compliances afterwards. A project comprises four yearly phases based on applying zones; initially designating and operating a specified risk zone, gradually expanding the special zones during a period of 3 years (2010-2012) and the final zone expanded to entire nation. In each phase, the intermediate version of the system is updated through a process of precise and unbiased validation in terms of its operability, feasibility and sustainability with building relevant infrastructures as needed.

Recently, local broadcast companies are experiencing financial shortages and business deterioration due to difficulties in securing income sources. This is due to the continuous decrease in viewership ratings as the contents of the broadcast companies do not attract the interest and participation of local residents. To resolve this issue, this paper presents a social network service closely coupled with local broadcasting. In the proposed service, the exposure range of articles is limited to a region so that reporters could easily find the interests of local residents. In addition, among the articles written by local residents, the articles requested to be broadcast by reporters are placed at the top section of the main page. From this UI configuration, local residents can easily recognize that their opinions can be directly connected to the broadcast, which is intended to activate their participation. The proposed service was implemented in the form of a prototype system with JCN, a broadcasting company in Ulsan, and this paper discusses its user interfaces, system structure, and an algorithm to estimate the priority of the written articles.
