In an IPTV system, the rights of the content and service provider can be protected by using Conditional Access System (CAS) and Digital Right Management (DRM). In case of the CAS, only the authorized user who has structured authentication keys can decrypt the encrypted content. However, since the CAS establishes a secure channel only between content provider and Smart Card (SC), it cannot protect the system against McCormac Hack attack which eavesdrops on unsecure channel between SC and Set-Top Box (STB) and SC cloning attack. In this paper, we propose a robust multi-STB assisted SC / STB authentication protocol which can protect the IPTV system against not only McCormac Hack attack, but also SC cloning attack. The previous works which bind a STB and a SC during the SC registration phase against the SC cloning attack does not support multi-STB environments. The proposed system which dynamically updates the STB information in subscriber management system using the bi-directional channel characteristic of IPTV system can support the user's multi-STB device effectively.

Digital Broadcasting serves a variety of broadcasting services for satisfying the requirement of customers. One of main factors for new broadcasting environment is interoperability between providers and consumers. For this interoperability, metadata standards are proposed for the digital broadcasting and TV-Anytime metadata is one of these standards. On the one hand, there are some researches for efficiently managing the broadcasting metadata on Set-Top Box. This paper proposes the metadata management system for efficiently managing the broadcasting metadata based on the STB which is low-cost and low-setting. Our system consists of a storage engine to store the metadata and an XQuery engine to search the stored metadata and uses special index for storing and searching. We expect that our system will keep the interoperability amongst a variety of applications for broadcasting because we adopts the XQuery for searching the metadata and the XQuery is a standard language for searching XML data.

Computer-based systems operating between two or more co-operating organizations as part of their business relationship are generally referred to as inter-organizational systems(IOS). IOS automates aspects of transactional work between organizations and coordinate other activities. These systems facilitate organizational interaction as well as flows of materials, services and information. This planning provides as business direction for IOS applications, coordinates the efforts of participants, and deals with technical and non-technical IOS issues. This paper seeks to research the effect of strategic determinants of IOS to the efficiency of IOS. The determinants that selected from prior researches are top management support, is support and vendor/consultant support. The results show that the effect of top management support to efficiency of IOS was significant and this effect mediates the effect of other factors.

The purpose of this research is to examine the major determinants affecting the usage and performance of information technologies in Daedeok Valley and Zhongguancun venture firms. The development of the research model is based on the theoretical linkages of IDT (Innovation Diffusion Theory) and TAM(Technology Acceptance Model). Seven hypotheses are derived and tested using regression analysis. The results from regression analysis suggest that the usage of Information technologies is affected by innovation characteristics (perceived usefulness) as well as organizational characteristics (top management support, employee capability on information technology acceptance) in Daedeok Valley venture firms. But, The results from regression analysis suggest that the usage of Information technologies is affected by innovation characteristics (perceived usefulness), organizational characteristics (top management support, employee capability on information technology acceptance), and external pressure (environmental uncertainty, intensity of competition) in Zhongguancun venture firms.

A management planning is an index to accomplish the goal of business enterprise and a managing guide of the top manager. It is a top manager's authority with he gives directions at the beginning of the budget year and has something to do with a responsible accounting. If we correlate this management planning with an area of accounting, we can subdivide it into followings; production and marketing schedule, demand-supply program of raw material, demand-supply program of the personnel and lobor cost program, facility investment program, balance fund program, profit and loss, and financial position program. I think, in the field of accounting for the sake of the management planning, there are motivation accounting, responsible accounting, divisional system accounting, evaluating accounting and so on. A management planning should be accomplishe and as it is accomplished, a business is going to be grown up and developed. Especially, it must be set up on the ground of the long-term strategies. When the accomplishment through the management planning, which is a social responibility that all the business enterprise are seeking after, is attained, it makes the development of business possible and we cannot dent that it is closely connected with the national economic development.

The study aims to provide some evidence of the effects of CSR practices on financial-based brand equity in Malaysia. Nowadays, many companies have embraced corporate social responsibility (CSR) practices because CSR is a vital component of the current competitive and complex business arena. It contributes greatly to social, environmental, and economic condition. With CSR practices, companies are able to achieve many benefits and there is evidence that CSR practices predict higher brand equity. However, little evidence has been produced concerning the effects of CSR practices on financial aspects of brand equity in developing countries such as Malaysia. Therefore, this paper aims to investigate the effects of CSR practices on financial based brand equity among Malaysia Top 100 brand. A CSR checklist instrument was used in the current study to examine the extent of CSR practiced. The results indicated that PLCs that were actively involved in CSR practices such as environmental, community, workplace and marketplace, found that this involvement enhanced their brand equity. The findings provide useful support and evidence for the management of PLCs in Malaysia, as well as companies in other developing countries, to engage more in CSR practices as a core element of their strategic and brand management.

In the era of disruptive change, a data-driven approach is vital to Human Resource Management (HRM) of any leading organization, for it is used to gain a competitive advantage. HR analytics (HRA) has emerged as innovative technologies since advanced analytics, i.e., predictive or prescriptive analytics, were widely used in the High Performing Organizations (HPOs). Therefore, many organizations elevate themselves to become HPOs through Data Science on the "people side." This paper proposes a systematic literature review using the Literature Weighted Scoring (LWS) to develop a conceptual framework based on three adoption theories, which are the Technology-Organization-Environment (TOE), Diffusion of Innovation (DOI), and Unified Theory of Acceptance and Use of Technology (UTAUT). The results show that a total of 13 theory-derived factors are determined as influential factors affecting HRA adoption, and the top three factors are "Quantitative Self-Efficacy," "Top Management Support," and "Data Availability." The conceptual framework with hypotheses is proposed to provide a foundation for further studies on organizational HRA adoption.
