This study aims to find out the effectiveness of regulation of promotional gifts and exemption of charges by analyzing the judgement criterion of illegality and the corrective action taken by regulatory agencies and suggests effective way of regulation. The results show that recently the differences of price-cut is getting bigger. In addition, Fair Trade Commission has considered discounts as unfair predatory price only if price is below the cost. But in the telecommunication business law enacted by Korea Communications Commission, 'expected profits per subscriber' has been applied as a key criterion. KCC's criterion is based not on the expected profit of individual service provider but on the averaged profit of services providers. It doesn't consider differences of service quality and the cost structure between dominant firm and late comers. Prohibition act of user discrimination result in the increase of subscriber and operating profits of late comers but this is not direct purpose of regulation. It can be desirable in the aspect of fair competition but since it may reduce consumer welfare, the criterion needs to be reconsidered.

Standard electronic tax invoice is a document standard for electronically exchanging tax invoices, which have been used in the form of paper for proofing business transactions. This standard focuses on the aspect of exchanging electronic documents between businesses and between businesses and NTS(National Tax Service), so it is limited in expressing semantics and contexts of financial information explicitly and economically for reusing them after their exchanges. Above all, it is needed to consider that they can be employed to various applications of businesses including financial reporting and auditing because they contain basic financial information about taxes and that they are reported to NTS. In this perspective, this paper compares and analyzes how to compose standard electronic tax invoice documents in XBRL with concrete examples, focused on the expressability and applicability, and discusses the possibility of XBRL-based standard electronic tax invoices.

The study derives various anticipated benefits resulting from locating small and medium sized IT service firms in a specific industrial cluster area. The study also derives IT service agility factors to obtain competitive advantages vital to real-time global enterprises. The anticipated benefits were then used to analyze how they improve the firms' agility. Using questionnaire data, factor analyses were used to figure out eight anticipated benefit factors including coordination, information sharing, business costs, speciality, communication, trust improvement, mutual business understanding, and reciprocity. The eight empirically derived benefit factors were then used to examine how they affect the IT service agility including flexibility, speed, responsiveness, and lean efficiency. The results of regression analyses showed that each one of the anticipated benefit factors except communication influence one or more IT service agility factors.

The current study is an attempt, in two separate surveys, to explore the role of motivation to lead, which has rarely been introduced into academic leadership research in Korea. For the survey and statistical analysis, the population is defined as the employees working in Korea. The motivation to lead is considered important in practices since without it any leadership development interventions show less possibility to succeed. The motivation to lead was defined in terms of three dimensions as in affective motivation, socio-normative motivation, and non-calculative motivation(Chen & Drasgow, 2001). The study then empirically explored the potential relationships between the three dimensions and leadership styles. Specifically, such leadership styles as transformational leadership, transactional leadership, and self-sacrificial leadership behavior have been correlated to motivation to lead. In addition, using regression analysis, the explanatory power of the motivation to lead on various dependent variables were investigated. As a result, the three dimensions of motivation to lead, that is, affective, socio-normative, and non-calculative motivations each were found to have strong correlations with transformational, transactional, and self-sacrificial leadership, as well as with other criterion-related variables such as organizational commitment and trust. Limitations of the current study, along with future research directions were also discussed.

Integration applications, such as EAI, B2Bi, need stable massive data processing systems during overload state cause by service request congestion in a short period time. In this paper, we propose the PLC (Peak Load Control)-based Worker-Linker pattern, which can effectively and stably process massive I/O transactions in spite of overload state generated by service request congestion. This pattern uses the delay time algorithm for the PLC mechanism. In this paper, we also show the example of applying the pattern to business-business integration framework and the experimental result for proving the stability of performance. According to our experiment result, the proposed delay time algorithm can stably control the heavy overload after the saturation point and has an effect on the controlling peak load.

In ebXML, a representative framework for electronic commerce, a BPS (Business Process Specification) should be finally defined as an instance of XML-version BPSS for the configuration of B2B (Business to Business) runtime systems . In order to define the instance more complete and consistent, it is required to validate all the semantic constraints on the instance . Due to the limitations of XML Schema constructs, however, current XML-version BPSS fails to specify formal semantic constraints completely. This paper presents how to find, express and reuse BPSS semantic constraints that could not be explicitly defined in the XML-version BPSS. The method facilitates the validation of XML-version BPSS instances easily with some useful guides for fixing violations of semantic constraints. Furthermore, B2B business processes can be standardized and applied more efficiently and effectively.

It is requested interoperability and inter-connection among technologies due to inertia and network externalities in the telecommunications industry. for that reason, firms in the telecommunications industry compete intensively against preempting their markets. Consumers' utilties can be increased, but searching or transaction cost of consumers may be decreased by standardization which is the core issue in the telecommunications. Also, standardization may prevent firms in that industry from overplus investment. However standardization may decrease the diversity of goods and technologies, so it can be the constraint factor in the consumption. In this paper, we'll examin the economic effects of standardization in the telecommunication industry and the effects to the industrial structure of standardization. After that, we'll suggest national policies in relation to standardization.

ISO 13584 Parts Library (PLIB) standard is making its way into e-business as a norm for classifying products and their characteristics. PLIB is a multi-parts standard, and the Part 42: Methodology for structuring Parts families Provides the information model and design Principles for the data dictionary of parts library or e-catalog. If e-catalog systems are built using a data dictionary that is constructed based on PLIB dictionary data model, many different e-catalog systems can be easily integrated and interoperated. This paper studies the roles and requirements of the data dictionary in e-catalog, and applies the data model and design principles of PLIB Part 42 to construct a data dictionary from the viewpoint of ontology Based on the analysis results, we propose a data dictionary of die and mold parts, and implementat the B2B e-catalog system.

Business Process Management (BPM) is an emerging trend of managing business process life cycles and integrating heterogeneous systems . Recently, BPM is considered as an essential element for automation of complex business processes involving many companies, particularly for those in an e-Business environment. In such an environment, it is very important for each business partner to trace history of resources. However, it has been a difficult problem for Workflow Management Systems(WFMSs) to support management of resource changes because of limited storage, complex process structure, and absence of formal change model. In this paper. a new framework is proposed, which can support change management for documents, one of core resources of business process. Under a traditional WFMSs framework, all workflow components belong to either build-time or run-time function, and executions of workflow processes are performed by the two functions . To manage changes of documents while process executing. a new framework with additional component modules are required. A version control method is introduced for the purpose of managing document changes. The proposed method includes five models for document structure, process structure, association between process and document, version management, and efficient version storage. A prototype system is developed to demonstrate the effectiveness of the proposed models.

To survive in the trend of the fourth industrial revolution, companies are putting a lot of attention and effort into personalization services using the latest technologies such as big data, artificial intelligence and the Internet of Things, while entrusting third parties to handle personal information on the grounds of work efficiency, expertise and cost reduction. In such an environment, consignors need to check trustees on a more effective and reasonable basis to ensure personal information safety for trustees. This study used AHP techniques to derive the importance and priority of each item of "Personal Information Safety Assurance Measures" for financial companies and trustees, and objectively compared and analyzed differences in perceptions of importance between financial institutions and trustees. Based on this, the company recognizes the difference between self-inspection of financial institutions and inspection of trustees and presents policy grounds and implications for applying differentiated inspection standards that reflect the weights appropriate for the purpose.
