In this paper, the downlink resource allocation of OFDMA system with decode-and-forward (DF) relaying is investigated. A non-convex optimization problem maximizing system throughput with users' satisfaction constraints is formulated with joint relay selection, subcarrier assignment and power allocation. We first transform it to a standard convex problem and then solve it by dual decomposition. In particular, an Optimal resource allocation scheme With Time-sharing (OWT) is proposed with combination of relay selection, subcarrier allocation and power control. Due to its poor adaption to the fast-varying environment, an improved version with subcarrier Monopolization (OWM) is put forward, whose performance promotes about 20% compared with that of OWT in the fast-varying vehicular environment. In fact, OWM is the special case of OWT with binary time-sharing factor and OWT can be seen as the tight upper bound of the OWM. To the best of our knowledge, such algorithms and their relation have not been accurately investigated in cooperative OFDMA networks in the literature. Simulation results show that both the system throughput and the users' satisfaction of the proposed algorithms outperform the traditional ones.

It is a challenging task to introduce and apply a theoretical concept like KM (Knowledge Management) to the corporate management by formulating such notion into a computer-based system. Apart from that, a company who suffers financially will be very much reluctant to employ KM, a solution that will not make an immediate impact on profit generation. Nonetheless, the perception of life-long workplace is being replaced by that of life-long career in today's society, and consequently it has become a key importance for the management to minimizing the Joss of valuable knowledge that results from frequent shift of manpower. Furthermore, knowledge is now regarded as a key to corporate competitiveness as its value has become a more important factor than that of physical resource in estimating a company's value. It is therefore necessary to transform such implicit knowledge that one possesses in his/her mind to a formation so that a company can achieve the ultimate goal of implementing KM: increase of profit and cost reduction. The objective of this research is to look into the case examples of the way in which Samsung Electronics implemented KM and help set the direction for those companies who consider employing KM into their corporate system.

최근 국내외적으로 사이버 공격 이슈가 증가하고, 국가 주요 기반시설과 정보통신망 보호가 중요해지고 있다. 이에 따라 정보보호 분야 집중투자 및 전문 인력 양성은 필수적이지만, 우리나라의 경우 정보보호 인력은 매우 부족한 실정이다. 현재 정보보호 인력양성을 위해 노력하고 있는 각 대학 정보보호 관련 학과에서 교과과정 설계에 많은 고민을 하고 있다. 이에 본고에서는 현재 운영 중인 국내 대학 및 대학원의 정보보호 관련 학과들의 교육과정 설계가 어떻게 구성되어 있는지 조사해보았다. 또한, 산업체에서 생각하는 필요 지식 및 기술과의 순위비교를 통해 실제 현장과 얼마나 차이가 있는지 SPSS를 활용한 통계분석으로 알아보았다. 이러한 분석을 통해 교육과정 체계의 미흡한 부분을 보완 할 수 있는 방향을 살펴보고자 한다.

최근 데이터를 활용한 분석에 대한 수요와 함께 분석 데이터인 지식 그래프의 크기는 점차 증가하여, 웹에서 수집한 데이터를 지식 그래프로 추출하였을 때 약 820억개의 엣지(Edge)를 가지는 수준까지 도달하였다. 많은 지식 그래프들은 웹 자원에 대한 메타데이터를 표현하기 위한 W3C 표준인 RDF(Resource Description Framework) 형식으로 표현되며, RDF 특성으로 인해 기존의 RDF 저장소들은 대량 RDF 데이터를 압축하고 저장할 때 처리 시간의 오버헤드가 발생하는 문제점을 가진다. 본 논문은 이러한 문제점을 개선하기 위해, 맵리듀스를 사용하여 대량 RDF 데이터를 정수 ID로 압축 변환하고, 수직 분할하여 저장하는 방법을 제안한다. 본 논문에서 제안한 방법은 RDF-3X와 비교하였을 때 최대 25.2배, H2RDF+와 비교하였을 때 최대 3.7배까지의 높은 성능 향상을 보였다.

An expert network administrator is not always stationed as disasters happen. In that case, it is desirable that a novice administrator is capable of taking part in network recovery operations as well. In this paper, an agent-based network management system in emergency situations is presented. We use the Active Information Resource based Network Management System (AIR-NMS) to relieve the human administrator from parts of her management tasks and present an interface that remotely can control this management system. The effectiveness of the system is demonstrated by experiments using a prototype system.

The purpose of this study is to suggest how the first birthday rite, a practice in Korean culture, has changed over the time. A survey of 250 mothers was undertaken from October 11th to November 6th, 2012. The research questions asked in this study are as follows. What general and expert views are held about the first birthday rite? What type of awareness and knowledge do mothers have about the first birthday rite? Is there any correlation between mothers' awareness and knowledge about first birthday rite? What is the importance of the components of the baby's first birthday rite and the importance of choosing first birthday rite goods? The data were analyzed using SPSS 17.0. Frequency, F-test, correlation were also employed. The results of this study are as follows: The first birthday rite shows a clear link to socializing. It is a family event, but is also seen as an opportunity to enhance relationships with relatives, colleagues, and friends. A banquet hall is chosen as preferred first birthday rite location, and participants are served a meal and receive gifts. The banquet information on first birthday rites was initially collected from the internet, blog cafes, and an experienced. However, it has become gradually more common to hire a consultant to organize the first birthday rite. Awareness of the first birthday rite is high, but knowledge is relatively low. In addition, there is a positive relationship between awareness and knowledge about the first birthday rite. When mothers are preparing for their baby's first birthday, they consider food for the guests' banquet, space and time. Finally, individual positive relationships were found between choosing first birthday rite goods and employee services, contract pricing for goods, and food for guests.

In this paper we describe an application of the lexical resource JurWordNet and of the Core Legal Ontology as a descriptive vocabulary for modeling legal domains. It can be viewed as the semantic component of a global standardisation framework for digital governments. A content description model provides a repository of structured knowledge aimed at supporting the semantic interoperability between sectors of Public Administration and the communication processes towards citizen. Specific conceptual models built from this base will act as a cognitive interface able to cope with specific digital government issues and to improve the interaction between citizen and Public Bodies. As a Case study, the representation of the click-on licences for re-using Public Sector Information is presented.

The 21/sup st/ century is a society based on knowledge, so in economic activities, it has emphasized the importance of information such as intellectual property or intangible asserts. Especially, according to the agreement on trade related as parts of intellectual property rights in WTO, it is used as the method of commercial entente and monopoly for intellectual property in an advanced nation. For this reason, WIPO and UNESCO discussed a complement for intellectual property on the foundation of traditional knowledge such as traditional knowledge (TK), genetic resources (GR) and traditional cultural expressions (TCE, folklore). Korea has a lot of knowledge falling under TK, GR, and TCE because of the long history of the country. In the case of traditional medical care, it has been used in the public health system. It is hard to apply these rights to traditional medical care of Korea because the laws of intellectual property have been established under the ideas of western culture. It is necessary to improve the classification system of traditional knowledge and patents. In the patent classified system of IPC, it needs to be related to the research between the classified system for massive technology and the classified system for traditional clinic technology.
