School library programs are a specific strategy connecting user to resources. Accordingly in order to strengthen school libraries, it is necessary for teacher librarians to develop partnerships that can form relationships between internal and external resources. As a result of analyses of partnerships appeared in current middle school library programs, its most programs are based on the internal reading events. In addition to, classroom teachers and external human resources rarely participate in the program. To improve these problems, it is essential to develop teacher librarians' leadership and collaborative networks fostering educational presence of school libraries in a learning community.

In this paper, we propose an efficient forecasting methodology of the mid and long-term frequency demand in Korea. The methodology consists of the following three steps: classification of basic service group, calculation of effective traffic, and frequency forecasting. Based on the previous studies, we classify the services into wide area mobile, short range radio, fixed wireless access and digital video broadcasting in the step of the classification of basic service group. For the calculation of effective traffic, we use the measures of erlang and bps. The step of the calculation of effective traffic classifies the user and basic application, and evaluates the effective traffic. Finally, in the step of frequency forecasting, different methodology will be proposed for each service group.

In this paper, we proposed a Virtual Machine Placement (VMP) method to provide live vertical scaling services for cloud resources. Since free space on the physical server must be secured in advance for vertical scaling, a "general-mixed-vertical" mode conversion algorithm based on the FirstFit placement strategy that variably adjusts the allocation ratio of virtual servers to physical servers for this purpose is presented. Simulations were performed using parameters such as vertical scaling ratio, virtualization ratio, and free resource ratio. When the vertical scaling ratio is 50%, considering free space, 150% of resources are required as a whole, but simulation results of the proposed algorithm show that only up to 125% of free space is required.

Competitiveness of a firm essentially depends on the value of the product or service the firm supply. Product or service of high value derives customer purchase activity. Service mix is the process which creates competitiveness by value creation for customers through optimal combination of physical characteristics of product and service. This research is to contribute competitiveness increase of Korean manufacture industry by study of the effect of service mix as to the business competitiveness. Usually competitiveness advantage approach relies on the industry structure competition theory and the resource-based approach. However, it is said that, while the industry structure competition theory helps finding attractive industry, it rarely helps finding which companies succeed or fail in the specific industry. The resource-based viewpoint approach is limited in that this cannot provide any theory or systematic frame for the analysis even though it has contributed a lot to the competitiveness increase. Power process approach is applied to this study in order to overcome this limit and to Increase the business competitiveness. Power process is the process to create the value, the source of power by interaction of power elements, value, needs, environment and relation, the five power determination elements. Power process is a process that creates value to satisfy the power objective for the attainment of the goals of the power subject. This study is to contribute for the manufacture industry by establishing service mix strategy from the power process viewpoint.

This study is to acquire a thorough understanding of the S&T level of Korea to serve as an important basis for the government policy-making, and to make basic information available to effectively promote the National R&D Program by survey of the overall S&T level in Korea S&T level survey is a comparison to the highest levels in the world to the third 3digit of the technology tree table. And, survey of technological gaps by year, during which Korea is able to reach the current level of the advanced countries. The findings of the surveys should be applied to strategic technology Planning for solving or narrowing the technology gap, e the major criteria for resources allocation in National R&D programs. And, the findings of the surveys should be the fundamental information used to establish strategic S&T policy in government.

The purpose of this work is to explore the role of international entrepreneurship(IE) in explaining internationalization process of Korean ventures and to structure the model of IE with the logics of effectuation. The internationalization of entrepreneurial company is regarded as the realization of entrepreneurship which find out and use opportunities across borders in this point of view, and the realization process gets more realistic and applicable to the internationalization of ventures by effectuation. So we constructed the new concepts of the generating-internationalization-outcome capability(GIOC), which is the effectual capability allowing ventures to go international despite their lack of internal resources and experiences. Its sub-capabilities of GIOC are extemporaneous coping capability, perform-resource-in-hand capability and network-use capability. The empirical analyses of the relations among the capabilities and the performances of internationalization are performed in order to prove the rationale of the model, which provides finally significant evidences of the relationships. The key contribution of this study is that it highlights the important role of IE in internationalization of ventures and shows the possible role of effectuation in explaining the realization process of IE.

현재 전 세계는 IPv4 주소 자원의 고갈에 대비한 IPv6의 도입을 위해 국가 차원의 전략적인 노력을 기울이고 있으며, 이에 따라 IPv4망에서 IPv6망으로의 안정적인 전이를 위한 상호 운영기술이 지속적으로 개발되고 있다. 이러한 기술을 적용하기 위한 다양한 응용 프로그램의 운영을 위해서 IPv6 기반의 DNS 기술은 그 핵심적인 요소라 할 수 있다. 그러나 현재 IPv4로 이루어져 있는 환경에서 바로 IPv6 환경으로의 변경이 어렵기 때문에 IPv6 네트워크 환경으로의 전이 과정에서 발생되는 IPv4와 IPv6의 네트워크의 공존 환경에서 트래픽을 안정적으로 전달하기 위한 기술이 필요하게 되었다. 이런 IPv4와 IPv6 상호 운용 기술을 이용하여 본 논문에서는 IPv4와 IPv6가 혼재한 망에서 안정적인 IPv6 Recursive DNS을 구성하기 위하여 상호 운용 기술 중 터널링 기술을 이용한 IPv6 Recursive DNS 구성 방안을 제시하여 혼재한 IPv4 와 IPv6 DNS를 운영하기 위한 구성모델을 제안한다.

This study is to suggest strategies for the aquaculture of marine fishes in Korea through the analysis of current domestic states and case studies of the advanced countries to enhance the competitiveness of the industry. To reveal the current state, a questionnaire study to the producers was carried out, and cases in Norway, China, Japan, USA were analysed in terms of national development strategies. From those analyses, 3 strategies for the improvement of the competitive edge in the industry were induced as followings. First, it is necessary to implement restructuring such as upsizing through consolidation of small units, networking, etc. Second, it is required to introduce the state-of-the-art technology with the newly-designed equipments to save energy and cost in the operation. Third, it is also required to implement programs to select the national strategic species and concentrate R&D resources on the selected ones.

The firms must perform both exploitation activities that efficiently use current resources and exploration activities that capture new opportunities. A company that simultaneously performs two opposite attributes, exploitation and exploration activities, is called an 'Ambidexerity Organization' or 'Organizational ambidexterity', which is called the Ambidextrous organization. This study examines whether the key factors of entrepreneurial orientation affect a firm's performance using two-handed strategies, and empirically analyzes the moderating effects of environmental dynamics. The results show that the entrepreneurial orientation has a significant effect on a firm's performance in the Ambidextrous organization. In addition, the moderating effect of environmental dynamics showed a moderating effect on the relationship between entrepreneurial orientation and organizational ambidexterity. This study not only suggests practical implications for SMEs, including venture firms and startups, but also has a significant impact on the relationship between organizational ambidexterity and a firm's performance. It is expected to make academic contributions by introducing variables and analyzing influential relationships.
