University books are an important information resource. University book resources can be shared not only in the traditional paper form, but also electronic form under the background of the Internet. In order to better manage the sharing of electronic book resources in universities, this study put forward three resource sharing strategies: centralized sharing strategy, distributed sharing strategy, and centralized-distributed sharing strategy by analyzing the combined development of books and the Internet as well as the significance and development of book resource sharing. The centralized sharing strategy, however simple, was difficult to handle large traffic; while the resource nodes were independent and self-consistent, the distributed sharing strategy was not easy to find and had a high repetition rate. Combining the advantages of both strategies, the centralized-distributed sharing strategy was more suitable for the heterogeneous form of university book sharing. Finally, a teaching resources sharing platform for university libraries was designed based on the strategy of centralized and distributed sharing, and three interfaces including platform login, resource search, and resource release were displayed. The results of the simulated comparison experiment showed that centralized and distributed sharing strategies had limitations in resource searching and had low efficiencies; the efficiency of the centralized strategy reduced with an increase in search subjects; however, the centralized-distributed sharing strategy was able to search more resources efficiently and main stability.

The purpose of this study is to identify the characteristics of the household labors that are performed by dual income families. The methodology that has been applied in this study was a qualitative research based on in-depth interviews of a total of 10 people(8 housewives, 2 husbands) selected from the 8 different families. The 8 different families have been selected in order to identify the different family lives and the various household labor patterns that are conducted by both the working husband and the working wife. As a result, we have found out that working wives still had to manage their time in an extremely busy manner in order to balance their professional work with their household tasks. However, the household work that was being shared by the husbands also seemed to vary dynamically according to the different family situations. Although, it has shown that household tasks are divided by the person's sex, the amount of household tasks that are shared tended to increase according to the life cycle of each family.

LTE-Advanced 네트워크에서 D2D 통신은 기지국의 부하를 감소시켜줄 뿐만 아니라 네트워크 성능을 향상시키는 통신 기술이다. 그러나 이 기술은 셀룰러 사용자와 D2D 페어들간에 자원을 공유함으로써 많은 양의 간섭이 발생할 수 있는 문제점이 있으므로 D2D 통신의 자원 할당 시 간섭에 의한 영향이 고려되어야 함에도 불구하고, 기존 자원 할당 관련 기존 연구는 셀룰러 사용자에 기할당된 자원 중 최고의 CQI 값을 가지는 자원을 재사용하여 D2D 페어에 할당한다. 이로인해 D2D 페어와 셀룰러 통신이 같은 자원을 공유하기 때문에 D2D 페어는 주 통신인 셀룰러 통신에 간섭을 야기하며, 기할당된 셀룰러 자원의 재사용으로인해 계산 복잡도가 높아지는 문제점이 있다. 본 논문에서는 이를 해결하기 위해 셀 내 간섭을 제거하면서 계산 복잡도가 낮은 D2D 자원 할당 알고리즘을 제안한다. 제안 알고리즘은 전체 자원 중 미사용 중인 자원을 임의로 선택하여 할당하고, 할당 받은 자원을 D2D 페어들간에 공유하게 한다. 즉 D2D 페어들 간 간섭이 발생하지 않는다면, 해당 페어들 간에는 같은 자원을 사용하도록 허용한다. 시뮬레이션을 통한 성능 분석 결과 비교 알고리즘에 비해 제안 알고리즘이 수용하는 D2D 페어의 개수에 비례하여 최대 11배까지 계산 복잡도가 낮아지는 것을 확인하였다.

Arabidopsis is well-known to the world's plant research community as a model plant. Many significant resources and innovative research tools, as well as large bodies of genomic information, have been created and shared by the research community, partly explaining why so many researchers use this small plant for their research. The genome sequence of Arabidopsis was fully characterized by the end of the $20^{th}$ century. Soon afterwards, the Arabidopsis research community began a 10-year international project on the functional genomics of the species. In 2001, at the beginning of the project, the RIKEN BioResource Center (BRC) started its Arabidopsis resource project. The following year, the National BioResource Project was launched, funded by the Japanese government, and the RIKEN BRC was chosen as a core facility for Arabidopsis resource. Seeds of RIKEN Arabidopsis transposon-tagged mutant lines, activation-tagged lines, full-length cDNA over-expresser lines, and natural accessions, as well as RIKEN Arabidopsis full-length cDNA clones and T87 cells, are preserved at RIKEN BRC and distributed around the world. The major resources provided to the research community have been full-length cDNA clones and insertion mutants that are suitable for use in reverse-genetics studies. This paper provides an overview of the Arabidopsis resources made available by RIKEN BRC and examples of research that has been done by users and developers of these resources.

본 논문에서는 다수의 머신 노드들이 동시에 LTE 시스템에 액세스 요청하고, 상향 링크 패킷을 전송하는 7단계 전송 과정을 고려한다. 모델링을 통해서 무선 자원 사용량을 분석하고, 부하가 집중되는 리소스를 파악한다. 시뮬레이션 결과를 통해 하향 링크 제어 채널인 PDCCH (physical down link control channel)의 사용률이 머신 노드의 수의 증가에 따라 급속도로 증가함을 보여준다. 이를 해결하기 위해 본 논문에서는 하향 링크 공유 채널인 PDSCH (physical downlink shared channel) 자원을 PDCCH에 할당한다. 이를 통해 PDCCH 자원 사용률이 개선 되었음을 보인다.

Originally the concept of the traditional resource sharing has been discussed in the context of bibliographic materials, and has been labor-intensive and high-cost activities. The technology has had a great impact on such pattern of the resource sharing, and has expanded the limited scope of the traditional concept into the sharing of library information in the levels of local, regional and national systems, and expertise, materials, facilities, equipments and personnels of the library system. While the traditional circulation service as a basic method to share library materials by users can provide the resource to a single person at a time, the electronic resource can be shared, by multi-users at a time anytime anywhere. The maximization of the electronic resource sharing requires that publishing process should be fundamentally changed and articles, books, chapters, speech manuscripts, music scores, maps, sound, and other formats of materials should be prepared in machine readable format. This study examined the positive effects of the technology on the resource sharing, but not investigate the concrete and complex problems as to the cost, guidelines, detailed procedures, design details, and intellectual properties and protection involved in the resource sharing. Some findings extracted from the study can be summarized as follows; (1) ILL will lose its meaning as a method to share the materials if they are all in the electronic format and the phrase 'networked information resource' becomes omnipresent. (2) The technology keeps on changing the concept of resource sharing. Today, the scope of resource sharing not only encompasses the sharing of the primary and secondary materials but also the sharing of the processings(eg. cataloging), expertise, user education, special facilities, and the integrated automated library systems. (3) The sharing of the networked resource will be a method to provide better services for library users in the low cost. (4) The a n.0, pplication of the technology to the resource sharing should be focus on the method which allows an end-users to do the direct access to the needed materials, and to be delivered the primary document as soon as possible.

Multicast and Broadcast Service (MBS) provides flexible and efficient transmission of the same information to multiple users using shared radio resources on WiBro network. The advantage of this service is to achieve the most efficient use of radio and network resources as well as to lessen sender's processing load when sending the same information to multiple users. Though radio resources are saved since a multicast or broadcast transport connection is associated with a service flow, it is hard to change MBS service channel dynamically. In this paper, we propose a Radio Resource Management System (RRMS) for supporting dynamic scheduling of MBS service channels. Results show that our proposed scheme using Radio Resource Allocation Table (RRAT) can efficiently support MBS services by providing dynamic schedule for MBS service channels.

In this paper we propose a resource management method which enables to guarantee the quality of experience (QoE) for handover in the overlaid macro-femtocell networks. How to cope with the resource demand of handover calls is necessary to efficiently support the movement of mobile terminals, the QoE degradation or the load control. We attempt to satisfy the QoE requirements of users and maximize the capacity of the system at the same time. In order to achieve this goal, this scheme divides the shared resources into two part for the movement of MT and QoE degradation, and allocates those resources with the competition between four types of handovers. Simulation results show that our scheme provides better performances than the conventional one with respect to the outage probability, data transmission throughput.

The purpose of this study is to analyze leisure studies in human ecology of Korea and to discuss them. For this analysis, the articles which were published on the Journal of Korean Home Economics Association, the Journal of Korean Home Management Association, and the Journal of Korean Family Resource Management Association were investigated by theme, research subject, and research method. Leisure studies in human ecology began with the survey of time-use or activity patterns and they were focused on the housewives. Since the latter half of the 1990' s varied groups -especially the old- are subject to sample, and the shared leisure is studied, varied themes are studied. The research method were deflected to the survey using questionnaire all throughout the period. For the future study, we suggest that the general theories developed and the appropriate research method applied.

In this paper, we propose an efficient interference management technique which controls the number of resource blocks (or subcarriers) shared with other cells based on statistical interference levels among cells. The proposed technique tries to maximize average throughput of a femto cell user under a constraint on non-real time control of a femto cell network while guaranteeing a target throughput value of a macro cell user. In our proposed scheme, femto cells opportunistically use resource blocks allocated to other cells if the required average user throughput is not attained with the primarily allocated resource blocks. The proposed method is similar to the underlay approach in cognitive radio systems, but resource block sharing among cells is statistically controlled. For the statistical control, a femto cell sever constructs a table storing average mutual interference among cells and periodically updates the table. This statistical approach fully satisfies the constraint of non-real time control for femto cell networks. Our simulation results show that the proposed scheme achieves higher average femto user throughput than conventional frequency reuse schemes for time varying number of users.
