In the telecommunications service industry, until now, it has been possible for Network Operators (NOs) to secure a competitive advantage to increase subscribers and profits through network investment. However, amid a big change to digital economy, network investment fails to lead to increase profits. These days platform companies without holing network infrastructure have a more competitive advantage and take more profits. This makes NOs gradually lose interest in network investment. The purpose of this paper is to find policy measures to promote network investment in digital economy. Specifically, we identify the factors influencing the network investment and promising policy measures energizing the investment, and then analyze their priorities and derive policy implications through Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP). The results of this paper show that market competition is more preferred to public intervention in promoting network investment. However, in order to guarantee and expand the universal access to network, it is necessary to consider expanding the role of the public, focusing on non-economic areas.

This study tries to find the possibility of differentiation strategy and looks into N+ advertising campaign of NAMSEOUL University that has been doing since 2011. N+ advertising campaign contains the meaning of educating leaders based on the foundation concept of NAMSEOUL University and develops consistent creativities through medium such as radio advertising, print advertising, on-line advertising and outdoor advertising. On the first of stage, the campaign develops the start and the meaning of N+ and organizes to get sympathy from target customers on the second stage. Nowadays, there are many competitions among universities to promote students. In this situation, the N+ advertising campaign of NAMSEOUL University is differentiate approach. It's also promotion for external publics to introduce the identity of University and effect for inducement of internal publics with pride and unity. Moreover, it suggests to universities what they have to consider.

The error networks due to the measuring systems and the test fixture must be previously calibrated in order to characterize the microwave devices. In this paper, it is presented a new method to characterize the error networks in which only two different microstrip lines are used for the calibration. Once each length of two calibrat- ing microstrip lines is accurately defined, the calibrated data can be easily obtained without acknowledgement for the propagation constant. The end effect is not considered when fabricated the microstrip lines used to calibration. The ATF13736 GaAs MESFET is characterized by means of the calibrating procedure with this method. The range of measuring frequency is 2 to 18 GHz, and the bias voltage and current are $V_{DS}$ =2.5V, $I_{DS}$ =20mA, respectively. Compared the calibrated data with data sheet, it is showed that the magnitude is nearly agreed with each other and the phase is deviated by 0.1 to 12 degrees in lower frequencies.

The emerging ubiquitous environment is improving IT technologies and the popularization of broadband Internet is encouraging creation and sharing of various contents. The contents include the concept of production and circulation of digital information/contents, in forms of characters, codes, voices, sounds, client and videos for being used on the Internet and networks. The contents are widely shared in networks and users can have a wide range of knowledge and gain the freedom of presentation from them. So now users participations are augmented gradually. However, many contents without acquiring agree of copyright are sharing on the Internet, so many problems happen in the manufacturing process of digital contents. To solve this problem, many research projects to limit contents utilization onto legitimate users and to provide secure contents protection and download, are in progress. Therefore, in this paper, we propose a secure D-CAS system (SDCS) which provides security for contents downloading.

In Korea we didn't have fundamental legal system on telecommunication until 'Communication Act'(Act No. 923) of Dec. 1961. After then, with rapid advances of technology and increases of request to telecommunication services in the field of telecommunication, circumstances around the telecommunication market have been changed. The market has been enlarged and slowed. Regulating of that field has been diverse and complex, Specially, as WTO went into effect, it's been recognized that standardization is more important for correspond to openness and liberalization in the field of telecommunication. In our country, national industry standardization began with 'Industry Standard Act of 1961', but it put mainly importance in manufacturing standard or industry standard till 1980's. Telecommunication standardization began to be active as TTA was set up in 1989. Now regulating rules to telecommunication standard are including 'the Fundamental Act of Information Promotion', 'Telecommunication Act', 'Act relating to Telecommunication Network Use Promotion, etc:, 'Software Industry Advancement Act','Knowledge Information Resource Act'. In this paper, we will survey regulating rules to telecommunication standard and Produce the future proposal to that.

The OECD estimates that a high concentration of intangible capital is in the richest countries of the world. Studies show that intangibles have a positive relation with economic growth. However, different types of intangibles can have different impacts on economic performance. Therefore, this paper attempts to distinguish the differences within the intangibles in influencing economic growth by analyzing three different characteristics of the intangibles. Three main types of intangibles (computerized information, innovative property and economic competencies) are analyzed based on the degree of tacitness, the process of creation and diffusion, and the level of embedded value-added. This research uses Polanyi's classification of tacitness of knowledge, the Nonaka-Takeuchi Model and the "smiling curve" to find that not only investing more in intangible capital but also developing more "tacit" type of intangibles are important for economic growth.

For the battlefield analysis, it is required to get correct information about the identification and moving status of target enemy units. However, it is difficult for us to collect all of the information perfectly, because of the technology of communications, jamming, and tactics. Therefore, we need a reasoning function that predicts and analyzes future moving status for target units by using collected moving information and domain knowledge. Especially. since the moving units have characteristics of moving objects, which change their position and shape over time, they require functions to manage and predict locations of moving objects. Therefore, in this paper, we propose a location prediction system of moving units for battlefield analysis. The proposed system not only predicts unknown units, unidentified units, and main strike directions to application domain for battlefield analysis, but also estimates the past or future locations of moving objects not stored in a database.

This study attempts to identify the influence factors on the numbers of visitors and reference room users of public libraries through log-log multiple regression models, using the Korean National Libraries Statistical Data 2018. The fact found is summarized as follows; Even though books collection and seating capacities might be the most important factors in attraction of visitors and reference room users to public libraries in the past when the storage and propagation of knowledge and information was the top function of public libraries, very various and compound factors such as cultural or lifetime education programs, library operation, and user activities have an effect on inducing people to visit and use public libraries at present. This means that these days, public libraries are being transformed into some kinds of comprehensive cultural center where software elements such as cultural programs, user education, events, budget, membership, opening days, building style and age, and group activities rather than hardware elements such as books, literature material, and facilities constitute their essential parts in connection with visitor and user induction.

In this paper, we propose an efficient dynamic workload balancing strategy which improves the performance of high-performance computing system. The key idea of this dynamic workload balancing strategy is to minimize execution time of each job and to maximize the system throughput by effectively using system resource such as CPU, memory. Also, this strategy dynamically allocates job by considering demanded memory size of executing job and workload status of each node. If an overload node occurs due to allocated job, the proposed scheme migrates job, executing in overload nodes, to another free nodes and reduces the waiting time and execution time of job by balancing workload of each node. Through simulation, we show that the proposed dynamic workload balancing strategy based on CPU, memory improves the performance of high-performance computing system compared to previous strategies.

승자독식(Winner Takes All)이라는 글로벌 경쟁원리로 인해 세계 주요 국가들 사이에 R&D 경쟁이 갈수록 치열해지고 있다. 이에 우리나라에서도 R&D 지원 확대 및 다양한 정책기획 활동 등이 전개되었다. 이러한 노력에도 불구하구 국가 차원에서 기획 및 정책조정이 효과적으로 추진되지 못하고 있으며, 국가연구개발사업 차원에서는 "기획의 양척 과다와 질적 부실"이라는 비판이 제기되고 있다. 반면에 기술 융복합화의 가속화 등 R&D 환경의 불확실성은 더욱 높아졌으며 국가연구개발사업의 규모 증가와 함께 연구기획의 복잡성은 더욱 더 높아졌다. 최근에는 국가 차원의 비전수립과 중장기 정책기획에 기초하여 사업기획과 과제기획을 연계 수행하는 등 기획을 통해 과제를 도출하는 하향식 접근이 강조되면서 기획의 중요성은 더욱 커졌다. 최근 연구기획의 새로운 기법으로서 정보분석 방법론(Information Analysis Method)이 대두되고 있다. 국가연구개발사업의 효율적 기획을 위하여 기존 기술기획 위원회(Peer Review) 방식 외에 정보분석 방법론을 통한 보완이 필요하다. 본고의 목적 크게 두 가지로 설명할 수 있다. 첫째, 현재 진행되고 있는 연구기획 및 연구기획 방법론으로 기장 많이 활용되고 있는 전문가 위원회의 한계를 제시하였다. 둘째, 최근 대두되고 있는 정보분석 방법론과 정보분석 시스템 구축, 그리고 이를 활용한 10대 기술(반도체, 디스플레이, 디지털 망원전파, 이동통신, BcN, 차세대 컴퓨팅, SW솔류션, 디지털콘텐츠, 임베디드 SW, 지식정보보안)에 대한 유망기술 발굴 실증분석을 실시하였다.
