We proposed a study on optimal clock period selection algorithm for low power RTL design. The proposed algorithm use the way of maintaining the throughput by reducing supply voltage after improve the system performance in order to minimize the power consumption. In this paper, it select the low power to use pipeline in the transformation of architecture. Also, the algorithm is important the clock period selection in order to maximize the resource sharing. however, it execute the optimal clock period selection algorithm.

Tailored for wireless local area networks, the present paper proposes a cross-layer resource allocation scheme for multiple-input multiple-output orthogonal frequency-division multiplexing systems. Our cross-layer resource allocation scheme consists of three stages. Firstly, the condition of sharing the subchannel by more than one user is studied. Secondly, the subchannel allocation policy which depends on the data packets' lengths and the admissible combination of users per subchannel is proposed. Finally, the bits and corresponding power are allocated to users based on a greedy algorithm and the data packets' lengths. The analysis and simulation results demonstrate that our proposed scheme not only achieves significant improvement in system throughput and average packet delay compared with conventional schemes but also has low computational complexity.

Organization's innovation capability is strongly tied to its intellectual capital or knowledge utilization. Employees play a key role in generation of intellectual capital and utilization of knowledge in a firm. Thus, the importance of human resource management (HRM) system for enhancing competency of employees and facilitating knowledge sharing between employees is getting its significance. In this paper, we highlighted the effect of HRM implementation to explain the reason of performance differences among firms, adopting the same ideal HRM system. The successful implementation of HRM system as well as the contents of HRM system was critical to enhance firm performance through HRM system. To investigate the effect of HRM implementation on firm performance, we proposed the three components of HRM implementation (i.e.; TMT philosophy, HR department capability and communication) in perspective of sense making and sense giving theory. Then, we analyzed the moderating effect of HRM implementation on the high commitment HRM - firm performance relationship. Empirical results showed that each component of HRM implementation positively strengthened the relationship between high commitment HRM and firm performance. In addition, the composite index of HRM implementation calculated by average value of three components revealed more significant moderating effect between the two. Furthermore, We discussed the academical and practical implications, and suggested future research directions.

대학도서관 자료의 전문화, 세분화된 학술정보자료의 공동수집 및 공동이용은 대학 내 연구의 활성화와 대학간 다양화, 특성화, 지역화를 추진하게 할 것이다. 이것은 국가 및 대학 차원에서 대학도서관의 특성화, 차별화 정책을 기반으로 할 때 가능할 것으로 보인다. 이에 본 연구에서는 대학도서관의 주제별 특성화를 기반으로 한 국가적 학술정보공동활용체계를 제안했으며, 구체적으로 두 가지 방안을 제시하였다. 첫째 한국교육학술정보원을 중심으로 형성된 협력망을 이용하는 방법과 둘째. 주제 또는 지역별로 형성된 각종 협의회를 중심으로 주제별 특성화를 유도하고 이를 활용하는 방법이다.

Plural governance system in which firms use vertical integration and market governance simultaneously are widely used across various marketing context. Typical examples of plural governance include franchise systems, in which firms own and operate some unit themselves while licensing the operation of some of their units to franchisees. Despite many scholars have attempted to explore the structure of plural governance over decades, there are few insights into its determinants. In this study, we examine the relationship between the proportion of outlets franchised and several franchisor's characteristics based on the perspectives of transaction cost analysis, resource scarcy theory and agency theory. Using franchisor data in Korean Franchise Disclosure Document over the 2006-2009 period, we test the effect of franchisor size, system growth rate, franchise fee, initial investment, and risk sharing on the proportion of outlets franchised. Except for the effect of system growth rate, the results of a series of multiple regression analysis supported the negative effects of franchisor size, franchise fee, initial investment and risk sharing on the proportion of outlets franchised.

The systematic management of technology infrastructure increasingly becomes critical as it represents the driving power for creating competitive advantage of nations and enterprises. In this sense, public facility and equipment, which is one major asset of technology infrastructure, should be managed effectively, systematically and efficiently to increase its overall equipment effectiveness. However, the manual and off-line communication was the unique way to communicate between the suppliers who provide facilities in the public sector and the customers who utilize the facilities in the industrial sector. This communication way caused invisibility of available usage time and increase of idle time, thereby decreasing the equipment effectiveness. This paper presents an web-based scheduling system that enables real-time collaboration and information sharing for increasing the equipment effectiveness. The designed system performs scheduling, facility management, order management and customer relationship management in an on-line platform, and carries out the processing and storing of relevant information in an integrated database. The paper includes a development approach to identify business process models and standardized system models by using object-modeling technique. The deliverable of the present work will contribute to increasing the equipment effectiveness by enhancing visibility, transparency and predictability by means of the integration with a legacy Enterprise Resource Planning.

센서 네트워크는 침입탐지, 원격 감시 등 보안이 꼭 필요한 환경에서 사용될 것으로 예상된다. 이와 같은 센서네트워크에서 기밀성과 같은 보안성을 제공하기 위해서 센서 노드들은 공유키를 가지고 있어야 한다. 현재까지 제안된 기본적인 키 분배 기법은 키가 너무 많이 필요하거나, 노출된 센서에 의해서 키가 너무 많이 노출되는 등 보안 측면에서 취약했다. 이와 같은 문제를 해결하기 위하여 확률적 키 분배기법이라는 적은 수의 키로 노드 간의 키 공유를 확률적으로 보장하는 새로운 키 분배 기법이 제안되었다. 그러나 이 기법은 노드 간에 키의 공유가 항상 보장되지 않기 때문에 물리적인 이웃 노드라도 통신을 진행하지 못하게 되어 비효율적인 라우팅이 발생하거나, 별도의 라우팅 프로토콜을 필요로 하는 문제가 있다. 본 논문에서는 쿼럼 시스템(quorum system)을 이용하여, 노드에서 필요로 하는 키의 수를 줄이면서도 이웃 노드와 키 공유를 언제나 보장하는 새로운 키 분배 방법을 제안한다. 또한 노드 분포 정보(deployment knowledge)를 아는 상황에서 쿼럼 시스템을 확장하여 센서 노드에서 필요로 하는 키의 수를 줄이고 보안성과 연결성을 지원할 수 있는 방안을 제시한다.

This paper proposes a novel framework for virtual content delivery networks (CDNs) based on cloud computing. The proposed framework aims to provide multimedia content delivery services customized for content providers by sharing virtual machines (VMs) in the Infrastructure-as-a-Service cloud, while fulfilling the service level agreement. Furthermore, it supports elastic virtual CDN services, which enables the capabilities of VMs to be scaled to encompass the dynamically changing resource demand of the aggregated virtual CDN services. For this, we provide the system architecture and relevant operations for the virtual CDNs and evaluate the performance based on a simulation.

Infinite competition on ICT industries is starting again. The basis of competence over global dominance will be human resource, a global ecosystem for products and national agenda for science and technology, etc.. This paper presents the six solution for the Global Competitiveness and Coexistence of Korean ICT Industries. Korea should nurture the brand of "World Best Korean ICT Forever" to secure technical competency of ICT related fields in global market. All ICT technologies should be aligned to global standard and market demand from beginning and the ecosystem around product needs to be established. System framework for utilizing the resource of core SW experts must be established. Through global partnership with China as manufacturing base for Korea-developed products, technical competency can be maintained including product planning. Security measure for technical assets is mandatory. Finally, core technology that will drive the future of ICT industries in Korea should be regarded as core subjects.
